"I lost my mom when I was a kid. Lost my dad recently. It's a scary world. People die. Trusts are betrayed. Things change. But change can be a good thing, you know? It can bring new experiences, new opportunities, people. You can treat 'em like a potential enemy or like a new friend. Just trust that everything's gonna be okay."

- Barry Allen

Bartholomew Henry "Barry" Allen (born c. 1989) was a scientist in the Criminal and Forensic Science Division of Central City Police Department. Barry is the son of Henry Allen and Nora Allen, the foster son of Joe West, and the best friend/boyfriend of Iris West. Barry's mother was murdered when he was a child and the blame was wrongfully placed on his father. He was taken in by Joe west and he dedicated his life to proving his father's innocence. After the S.T.A.R. Labs particle accelerator exploded, it caused a giant thundercloud to form and Barry was struck by lightning, falling comatose for nine months. When he woke up from his coma, he discovered that he had developed superhuman speed and various other abilities derived from it. Using these super powers, he began acting as the vigilante and superhero known as Red Streak or The Streak. Soon after, the public recognized him as The Flash, stylized as the Scarlet Speedster.

Early life
Barry Allen was born in 1989 to Henry and Nora Allen as an only child. At some point in his childhood he met Iris West who he became best friends with, and soon after formed a crush on her which her father Joe and both Henry and Nora were aware of. However Barry was also bullied by Tony Woodward and came to greatly resent him.

On March 18, 2000 when Barry was eleven years old, he ran home from school after getting into a fight. Though not being fast enough, his mother promised that he had a good heart, and his father was proud of him for winning the fight. Later that night Barry was comforted by his mother when he admitted he was afraid of the dark but she convinced him he wasn't afraid of darkness itself, just being alone in the dark and wished him sweet dreams. Later that night Barry was awoken by a commotion and went downstairs and saw his mother, surrounded in streaks of red and yellow lighting. Barry attempted to reach his mother but she told him to stay back and a midst the streaks Barry saw a yellow suited figure for a brief second, and his father told him to run. At that very moment however Barry suddenly found himself 20 blocks away. Barry returned home in time to see his father being arrested by police, the former who told him not to enter the house. He entered, seeing Joe standing solemnly over a body. When he walked away, Barry approached the body and discovered, to his horror, that it was his mother. Following the ordeal, Barry was fostered by Joe and Iris. This also caused an inhibitor between Barry and Iris as growing up in the same household prevented their feelings (at least on Iris' side) to mature beyond sibling love.

Initially, Henry asked Joe to not let Barry see him. Not knowing this, Barry kept trying to run away to see his father at Iron Heights, and he was caught and stopped by Joe every time; at one point, Barry called him out for it, telling him that he wasn't his father and that he hated him. Eventually, Barry finally reached Iron Heights before Joe could stop him, and he finally came face to face with his father. Henry told him that he simply did not want Barry to see him in prison. Despite this, Barry begged for his father's release, insisting that the man in the lightning was who killed his mother, not Henry. Henry told him that he couldn't help him and asked that he be a good boy and let Joe raised him. Henry was promptly taken away and Barry became more accepting of Joe as his new guardian.

6 months after the murder Barry was still depressed and became grumpy towards everyone. Joe saw this and understood why he was acting angry because he didn't want to let the pain of the grief in, fearing his father and mother would be disappointed in him if he did. However Joe convinced him it's ok to let the pain in and Barry finally let himself feel the grief and cried, to which Joe comforted him and promised that he'd always be there for him.

In school Barry was relentlessly bullied by Tony Woodward. Joe noticed this and had Barry spar with Iris who easily beat him. Joe then told Barry that if he ever got into a fight he couldn't win that it was okay to run the other way. At the age of 12, Barry went to a reptile camp, which was paid for by Joe. In high school, Barry attempted tryouts for the high school football team, however, failed horribly, making Joe swear to never talk about it again.

Barry had graduated from college majoring in two fields of science. It was with this skill that Barry was motivated by his mother's murder to study criminology, in the hopes of proving that his father was innocent. Barry admired many successful scientists but his idol who he was practically obsessed with was Dr. Harrison Wells, scientist who was in the midst of developing a particle accelerator that would open new fields of science and change the world. Barry came to idolize Wells so much he would have paid for his autograph and ready his autobiography twice.

Visit to Starling City
Years later, Barry arrived in Starling City. He wasn't able to initially get a cab as the driver pulled away, and he soon arrived at Queen Consolidated's Applied Sciences Division to investigate a mysterious break-in as a CSI from Central City with a connecting case, where he met Oliver Queen, John Diggle, Quentin Lance and Felicity Smoak (the latter whom he had an instant connection with).

He was set up in the division with Felicity's help, unknown to Barry, because Felicity believed that they should have used him as an asset seeing as forensic science. The two began talking, and Barry began speculating about The Arrow and his background, making incisive observations about why The Arrow wore green instead of black, the type of arrows he used, and how he theorized that The Arrow has partners, particularly someone who had a background in computer sciences; all of this unnerved Felicity.

Barry was astounded when Felicity asked him to help with a blood sample from an arrow she received from the police both by her "connections" from working for Oliver, and the fact that he was working the same case as The Arrow. During that particular part of their investigation, Felicity invited Barry to a Queen Consolidated function, which was actually a party at the Queen Mansion. However, before the results came in, his cover as a crime scene investigator working for the police was blown by Oliver just after he and Felicity began arguing over a news report about the mass particle accelerator. It was revealed that he was just an assistant CSI and there was no connecting case in Central City. Barry explained what happened to him as a child, and how it had caused him to begin looking into cases with impossible circumstances, in hopes of one day proving one possible, therefore solving his mother's murder and freeing his father. He was later re-invited by Oliver as Felicity's plus one to come to his home where he was throwing a party for his mother. When there, he apologized to Felicity while they danced.

After the party, Barry was contacted by Singh and was told to return to Central City if he hoped to keep his job, and revealed the sedative used was ketamine, informing Felicity it should have been easy to track. He tried to catch the soonest train, though missed the last one of the night. He settled down in to the train station to wait for the next one in the morning, when suddenly he was hit with a tranquilizer dart to the neck. When he awoke, he found himself in Oliver's base with Diggle watching him and Oliver lying on a table in full Arrow costume. Felicity approached him and asked Barry to save Oliver's life, who was not only poisoned with an unknown substance from the A.R.G.U.S. disaster bunker, but also had been beaten by the robber who had stolen the centrifuge from Queen Consolidated, raided the blood bank, and encountered Oliver as The Arrow while stealing large amounts of ketamine from the bunker.

Barry was able to save Oliver's life, which Oliver was not too pleased with at first, as they had revealed his secret without his permission. However, Barry eventually gained Oliver's trust. He recommended that a mask would be better than the green grease he used on his eyes as better concealment of his identity. Oliver later asked him if there were any side effects to the rat poison he injected in him, and Barry told him that it could cause hallucinations and heavy sweating. He then discovered that Oliver's hallucinations weren't from the serum, and that it was psychological. Barry soon after headed back to Central City.

The accident
On his train back to Central City, Barry encountered Martin Stein and the two discuss physics and Harrison Wells' particle accelerator and how it would change the world. After he got off the train, he soon headed back to work, arriving to a crime scene late. He was successfully able to identify the getaway car from the robbery and also grabbed a sample of some animal feces found on the ground, before heading back to his lab to examine the evidence. While processing the feces, he was greeted by Iris. Barry discussed the S.T.A.R. Labs particle accelerator, noting that it provided ideas that were far beyond their current capabilities of science, hence why he was so excited. Detective West approached right as the feces had processed. Barry described the results found, explaining that it had a chemical used only at four different farms around town, suggesting they check them out. Following, Barry and Iris headed to the unveiling and switching on of the particle accelerator. Barry attempted to convey his attraction towards Iris, but she simply misunderstood it. They began listening to Dr. Wells who described how the particle accelerator would lead to a much greater future. As they were listening, a guy stole Iris' bag along with her laptop inside it. Barry ran after him, attempting to catch up to him, however the guy knocked the wind out of him and ran off (only to later get caught by Detective Eddie Thawne). At the police station, Iris and Barry mocked Eddie, a new transfer from Keystone City. Later Barry headed to his lab, watching the news of the S.T.A.R. Labs particle accelerator, but as he watched it, it became unstable. The particle accelerator sent a shock-wave through the city, and only seconds later was Barry struck by a red bolt of lightning through a window in the roof. He was sent backwards through the already-charged chemicals and was knocked unconscious. A red flash of light appeared across his cheek, rising, and then faded away. He was quickly rushed to hospital, where he was kept on life support whilst in a coma.

For the following five weeks, Felicity Smoak visited Barry in the hospital while he was in a coma, and left only to help Oliver. Barry's heart constantly seemed to stop working, however it was concluded by Harrison Wells, who begun to visit him, that his heart was in fact beating too fast to even register. When Barry's condition began to worsen he was moved to S.T.A.R. Labs to be closely monitored and was frequently visited by Iris West. Barry was visited by his friends and relatives at the hospital frequently. When Iris came by one day, she received a static shock as she grabbed Barry's hand.

Becoming the Flash
When he woke up from his coma 9 months later, Barry met Dr. Wells, Cisco Ramon and Caitlin Snow. He learned of his coma and how it had been caused by the explosion of the particle accelerator. Much to their annoyance, Barry chose to leave, claiming that he felt normal. Barry went to meet Iris at her work, where the two embraced, Iris incredibly thrilled to see Barry awake and walking. As they talked, Barry noticed time slow down, then fasten back up again. Iris grabbed her jacket, then they went to visit Joe at the police department. Joe was more than happy to see Barry, though he was called to a robbery at Gold City Bank. Detective Thawne followed West, also expressing his happiness at Barry's return. As they left, Barry noticed a rough detainee, who quickly reached for a police officer's gun. Before he could grab it, Barry sped over to him and back, stopping him from doing anything.

Freaked out by the incident, Barry promised to call Iris that night and left. Once outside, Barry noticed his hand shaking at an unbelievable speed, shortly followed by him accidentally almost running in to a bin at super speed, then breaking the back window of a cop car. Realizing the gifts he had, Barry went off running, testing out his super speed. Before long, he accidentally ran through the back of a van. Sometime later at an airfield, Barry met with Cisco, Caitlin and Wells. He put on a tight suit and got ready to run. Dr. Wells cautioned restraint, whereupon Barry began to run at full pelt.

Partway through, he began to remember the night of his mother's murder, specifically a ball of lightning with a man seemingly inside it surrounding his mother, and he crashed, fracturing his wrist. Back at S.T.A.R. Labs, they discovered that Barry's wrist had healed in under three hours, much to their amazement. Dr. Wells inquired as to what happened, and Barry explained what he'd remembered: a man somehow inside a ball of lightning. Barry raised the question that perhaps there were more people like him, but Harrison rejected the idea, claiming that Barry was unequivocally one of a kind. Following that, Barry went to meet Iris at Jitters. He looked upon Iris and Eddie kissing, and they soon took a walk as Iris explained to Barry how the two of them had met, asking him to promise not to tell her father. As they talked, a police car involved in a car chase slammed on the brakes, leading to Barry pulling Iris out of the way as the car hit the wall under the bridge. As the other car raced by, Barry recognized its driver: the seemingly dead Clyde Mardon. Barry ran after the car, crashing through the side and entering. Before Mardon could get his gun out, Barry grabbed the steering wheel, making the car tumble on its side, on to its top. Mardon exited the vehicle, relatively unscathed and Barry quickly followed.

He called out to catch Mardon's attention, but soon the area was flooded with fog, apparently made by Mardon himself, causing a car to run in to the already overturned car, forcing Barry to speed to a nearby patch of grass for safety. Paramedics soon arrived, along with the police, including Joe. Joe scolded Barry for having Iris out in the open and Iris for having followed the danger. Barry took Joe aside, telling him of his belief that the car was driven by Clyde Mardon, who had apparently survived a plane explosion, also somehow gaining the ability to control the weather. Despite various pieces of apparent evidence, Joe didn't believe him. Frustrated with Barry's seeming fantasies, Joe explained how his claims were impossible, including the ball of lightning with the man inside; he knew Barry's father was the murderer, as did numerous others. Having never asked for anything from Barry, Joe asked Barry to for once be realistic, to which Barry simply walked off, disappointed.

He returned to S.T.A.R. Labs, angry at Wells for lying to him about being the only one affected by the particle accelerator's explosion. Dr. Wells claimed to not be entirely sure, as there had been numerous amounts of radiation including anti-matter, dark energy and x-elements, all apparently theoretical prior to the event. Despite them only being theory up to that point, Wells claimed that Barry was proof otherwise. He went in to more detail, explaining that they'd been looking for more "meta-humans", a term they'd coined for people like Barry. Barry brought up Clyde Mardon, whom they had to stop before he hurt anyone again. Wells cautioned Barry to keep himself safe, as Barry had the potential to unlock previously undiscovered vaccines, medicines and breakthroughs in science, yet he wished to put himself on the line and "play hero". Dr. Wells saw him as nothing special, just a boy who'd been struck by lightning. Upset by Harrison's statement, Barry called Oliver Queen, hoping to get some advice. He visited Oliver in Starling City, where he expressed that he believed Barry could save people, though in an entirely different way to The Arrow. As opposed to The Arrow's tough vigilantism, Barry could be a guardian angel to the people of his city, saving them "in a flash". As he speeds away, Oliver expressed his awe at Barry's powers. Barry headed back to Central City, to S.T.A.R. Labs. He apologized to Caitlin and Cisco, understanding that they'd lost things in the explosion, but there had been an increase in crime, presumed to have led from the creation of meta-humans. They agreed to help, and Cisco even suggested the use of a suit he'd made, initially for a firefighter, but believed it suited Barry well. He put on the suit and raced to Mardon's farm, where they'd noticed an acute change in the weather. He saved Joe and Eddie, who'd come to investigate, after a piece of debris flew at them. With Mardon's tornado heading towards the city, with an increasing wind speed, Barry suggested that he run around the tornado in reverse in order to unravel it. Despite Caitlin and Cisco's belief that Barry might not hold up, he proceeded to run around it. Before he could run fast enough, Mardon knocked him away. Believing him to be too strong, Barry didn't think he could beat Clyde. However, as he was about to give up, Dr. Wells began communicating with him. Despite acting selfishly, Wells expressed that he truly, deeply believed that Barry was special, that he could help stop the havoc he'd created. With the confidence boost, Barry was able to run fast enough, clocking just over 700 mph, ultimately unraveling the tornado. After being knocked to the ground, both Clyde and Barry stood up. Clyde proceeded to point a gun at him, claiming them to be the same, though Barry strongly disagreed. Before he could shoot Barry, Joe intervened. The following morning, still at the crime scene, Joe and Barry discussed Barry's powers and Joe apologized, for not believing him and for also believing his father a murderer. Barry also promised not to reveal anything to Iris so as to keep her safe. Not long after, Barry visited his father in Iron Heights Prison, assuring him that he still believed in him, that he was incredibly proud to be his son. After that, with a lightning bolt symbol added to his suit, Barry ran through the streets of Central City, saving a man from crashing on his bicycle.

Early days and setbacks
Barry continued to save citizens throughout Central City, much to the frustration of Caitlin and Joe. At his day job with the CCPD, Barry investigated a strange robbery and murder scene wherein the surveillance footage showed one man, but evidence indicated that there were at least six present. He later made a casual remark that the perp's footprints were about the same size as those of Captain Singh's but was reprimanded for it by Joe, who reminded him not to tell Iris about his ability. Later, Barry went to Stagg Industries with Iris, where Simon Stagg was set to receive an award from Central City University. Iris was covering the event for her journalism assignment and needed Barry to help her with the scientific parts. At the event, the armed gunmen responsible for the scene Barry had just investigated came arrived and was in the process of taking their valuables when a security guard attempted to stop them. Just before they could shoot him, Barry saved him and went after the robbers, only to lose consciousness along the way. After his fainting, this prompted the S.T.A.R. Labs scientists to investigate Barry's recent weaknesses. After a run at a "Cisco'd" treadmill, it was discovered that Barry had acute hypoglycemia, a condition that Barry developed because of his sped-up metabolism and could be remedied by a more extensive meal plan. Joe then arrived at the lab and called him out for his unnecessary heroics. Because of this, Barry lost confidence in himself and, face to face with Danton Black, the meta-human that infiltrated the Stagg event, he realized that he did not have the ability to really go up against them. At this point, Iris was still trying to get Barry to tell her what was going on with him. Just when he had momentarily quit his association with Wells and the others, Iris revealed that her new journalism topic would be his alter-ego, who has been dubbed the "red streak" by citizens. Caitlin then called Barry back to S.T.A.R. Labs and told him of a way to defeat Black. Joe then arrived to convince Barry to go after him. Barry did and followed Danton to Stagg Industries, where he intended to kill Stagg once and for all. With pep talk from those at the Lab, including Joe, Barry was able to isolate the real Danton from the hundreds of clones and put him down. When Danton momentarily regained consciousness, he attacked Barry only to miss and hit the window. Barry tried to save him from falling but Danton, not wanting to be saved, summoned up an extra hand to pull him from Barry's grip and fell, much to Barry's disappointment. Later, Barry commended the group at the lab, who then fully supported Barry's city-saving, even Caitlin, and made amends with Joe.

Barry went to the movies with Iris when Cisco and Caitlin informed him of a car chase. Using his speed Barry quickly stopped the robber and returned before Iris knew he was gone. The next day Barry and Joe investigated the death of the Darbinyan crime family. Noting that as the victims were poisoned with gas they would have all died at the same time, yet some of them had time to move. This led to Barry realizing that they were dealing with another meta-human who could control gas. At S.T.A.R. Labs, Joe brought up the topic of finding a suitable prison for meta-humans. Wells and Cisco decided that the particle accelerator would be the best place to hold them until they could cure them of their powers. Caitlin, remembering the death of her fiancé Ronnie, froze in her spot. Seeing her distraught, Barry offered for Caitlin to help him run tests on the poison gas they'd procured. At Barry's lab the two talked about Ronnie until the DNA results came back, revealing that the gas inside the victims also had someone else's DNA. Hearing of the murder of Theresa Howard on the police radio, Barry left despite Caitlin pleads. Arriving at the scene, Barry found himself too late and angrily chased after the meta-human. Before he could fight him, the man transformed in to gas and forced Barry to inhale him. Rushing back to S.T.A.R. Labs, the team were able to painfully extract the gas with a needle. Despite being told to rest, Barry went to talk to Joe and confide in him about his inability to save the judge. He went on to mention his temptation to break his father out of jail, though Joe reasoned that his father would simply be a fugitive, and despite his abilities, Barry would never be able to save everyone. Later Barry apologized to Caitlin for worrying her, only for Caitlin to reveal that what he had said to her were the same last words Ronnie said before he died. Barry decided to help her overcome her fear of walking into the particle accelerator. After finding peace, she thanked Barry and the two embraced. Wells and Cisco soon called them up and revealed that a sedative was also found in the gas. Barry told Cisco to check if anyone was executed on the night of the particle accelerator, as the two chemicals were used when executing death-row inmates. They identified the meta-human to be Kyle Nimbus, a hit-man for the Darbinyan crime family, who turned on Nimbus, leading him to be arrested by Joe West and prosecuted by Judge Theresa Howard. Barry quickly suited up and headed to Iron Heights prison, saving Joe who was visiting Barry's father. Barry then went after The Mist, as Cisco proudly nicknamed him, defeating him by tiring him (meaning he would be forced to revert to his human form eventually). Barry later visited his father and confided in him they he missed his mother. Henry comforted him by telling him the story of how he learned to walk. Barry realized that to honor his mother he had to continue running, as he had always done.

Barry trained the speed of his mind by multitasking by playing a game of chess with Harrison Wells, a game of Operation with Caitlin, and a game of table tennis with Cisco. Barry defeated Cisco and Caitlin but made a mistake which caused him to lose against Wells. Soon after, they had an alert of a bank robbery, to which Barry responded to quickly. At the scene, Barry managed to unmask Leonard Snart, the leader of his crew. After a guard was shot, Barry quickly rushed him to St. Andrews Hospital and quickly returned to the scene for work. When Captain Singh noted that a guard said there were three robbers, Barry corrected him to four, though he quickly justified his reasoning as it had to of been a four-man job. After Singh sarcastically thanked Barry for his insight, Joe asked if Barry saw anything that could help the case, to which Barry told Joe he saw one of them unmasked. At the prescient, Barry quickly identified Snart to which he learned that Snart's father was a dirty cop. Later when Iris brought Barry coffee, Barry was told by Iris that she began a blog about The Streak. Barry failed to convince her to stop with the blog as it only brings crazies and trolls. Barry was shocked when he saw Felicity in his office. Barry caught up with Felicity to which he learned Felicity listened to his entire conversation with Oliver on the rooftop. Barry showed Felicity his powers and brought her to S.T.A.R. Labs. When asked if they could trust Felicity, Barry told Cisco and Caitlin that she works with The Arrow, reassuring them. Barry showed his powers again, using the treadmill to which Barry attempted to show off by running backwards, though he failed. When Barry brought Felicity to Jitters, he was invited by Iris to join her and Eddie to Trivia Night and to bring Felicity. When Iris asks why Barry isn't dating Felicity who she claims to be the perfect girl, Barry states that they are only friends. At trivia night, Barry and Felicity answer a majority of questions correctly. Iris then pushed Barry to ask Felicity out again, assuming Felicity was very interested in Barry based on how she dressed. After Snart was spotted, Barry left and had Felicity cover for him, though she had no excuse that could work for him. Barry arrived in time to save Joe and a few others but due to the fact he was struck by the cold gun when saving Joe, he was slowed down and failed to save a security guard. Barry later was furious at Cisco for building the weapon which caused the death of a man. Barry felt betrayed as he was never notified of such weapon, causing him to be unprepared. Barry quickly learned Cisco originally made the gun to be used on him, had he gone uncontrollable. After the team tracked Snart, Barry decided to take him on his own and turn off all communications. When Barry confronted Snart, Snart notes that Barry's weakness is his altruism always saving others, rather than go after the villain. Snart froze the wheels of the train, causing it to derail as he fled. Barry having no choice, managed to rescue all passengers though he was attacked by Snart. Before Snart could finish him, Barry was saved by Cisco, Caitlin, and Felicity. Back at S.T.A.R. Labs, Barry said his goodbyes to Felicity, though he later chased after her and hopped on her train. The two had conversations on relationships before sharing a kiss.

Barry was hanging out with Cisco, Caitlin, Iris, and Eddie at a bar where he discovered that because of his high metabolism he could not get drunk. Suddenly an explosion was reported at a building Barry raced over to see a window washer about to fall, thinking of no other way to save him Barry asked Cisco and Caitlin how fast he would need to go to run up a building. They told him that if he moved at extremely fast speeds he would be fine but must maintain his speed on the way down or risk serious injuring. Barry rescued the man but was seen by Iris. blurring his face so she couldn't recognize him he quickly left. Later as police investigate Barry noted that he could find no bomb casing to Joe. Searching through the files using his powers Barry found some information that pertained to the incident. Back at the police station Barry was told by Joe to give the military everything they had on the case. Barry handed the files over but using his speed managed to snatch one file from them. Joe told him to consult with the crew at S.T.A.R labs. At the lab Barry told them of what happened. Wells was familiar with the general leading the investigation, Wade Eiling. Wells explained that he worked with Wade to develop gene therapies for soldiers while Wells was concerned for it benefiting civilians only for him to severe their partnership when he found out Eiling's plans for developing mind reading abilities for interrogation purposes. Cisco went through the army's digital records where they discovered the culprit was a woman named Bette Sans Souci, a bomb specialist for the army. Barry found Bette at her last known address however when tried to take her in contact with her caused his clothes to begin to detonate Bette told Barry to get out of his clothes before they exploded which he did just barley escaping the blast. Back at Star labs Barry told a distraught Cisco about the suit and revealed to the others she was a meta-human. Joe came him and asked Barry why he didn't tell him Iris saw him the other night. Barry told him she caught him off guard so Joe told him to tell Iris to stop blogging about him. Barry begged Iris to stop but she refused claiming that he himself wanted to know to find out about the impossible since they were young Barry noted that she wasn't even putting her name on it, Iris told Barry to talk to her when he told her the truth of why he was being so skeptical. Cisco and Caitlin called and told him that Bette was spotted at the location of the surgeon who experimented on her. Barry arrived just in time to save Bette from being captured. Back at Star Labs the others told Bette of how the Particle Accelerator explosion and how it changed her.As they examined her Caitlin discovered a tracked inside her graze wound when the army attacked her, leading Wade right to Star Labs. The others quickly got her got her out while Wells stalled Wade. Outside while testing her abilities Bette asked Barry if the others had tried to help him find a cure. Barry told her how a friend once told him that the bolt struck him for a reason and now because of it he can help people. Joe called and told Barry that Iris put her name on her blog. Barry confronted her as the Flash and told her to stop writing about him. Iris revealed that to him that she was writing to help Barry prove that the impossible does exist. Barry arrived at Star Labs where the others revealed to him and Bette that curing her was at the moment impossible. Barry suggested that they join her but the others pointed out that Bette's powers were to destructive and could put them all in danger despite Barry pointing out she was the first meta-human they encountered who was not a criminal or a person to use their powers to hurt others. Back at his lab in the police station Barry met up with Joe. He told him that by visiting Iris as the Flash he found out that Iris was only writing about him to help. Barry pointed out that the only way to get Iris to stop was to tell her the truth claiming he told her everything only for Joe to reveal he been knew Barry had feelings for Iris since he was a child and noted that Barry has not told Iris his feelings about her. Barry claimed it didn't matter since she was already dating Eddie but Joe told him that went fate wants something to happen whether it be him getting hit by the bolt that gave him his powers or getting two people to fall in love it works things out. Back at Star Labs the others told Barry Bette had left without saying where she was going. When they finally found her about engage Eiling and his men Barry rushed to her location before she could kill him. As Barry talked her out of killing Eiling the general shot her killing her. As her body began to detonate the others told Barry to get her remains out of the city. Barry asked them how fast he would have to go to run on water. The team guessed about 650 miles per hour but told him he must escape the blast once he dropped her. Barry did and just barley managed to outrun the shock wave. Later as Eiling covered up the incident Barry expressed disappointment, as Eiling had killed Bette in cold blood right in front of him and yet they could do nothing to him. Caitlin tried to comfort him telling him that running on water put him in interesting "company". Back at Joe's house Barry told Iris about his situation with Bette without telling her the specific details and asked her one more time to stop writing about the streak. Iris again refused forcing Barry to tell her that they should not talk to each other for a while.

Later Barry visited Iris once again as the Streak and tried to convince her to stop writing about him. However she ignored his request and instead tried to find out more about him. She then asked what she should call him with Barry claiming anything would be better than "the Streak". Their conversation was cut short when they heard sirens. Rushing to the crime Barry saved a kid who was about to get ran over by the culprit. Cutting the criminal off, Barry discovered he was a meta-human when the man rip the door off of the door of Humvee he had stolen and threw it at him. Barry dodged this and attacked the man, only for his skin to turn into a steel like substance which resulted in him injuring his hand and the man brutally back handing him. Beaten Barry escaped but not before the criminal told him that he was "born to take a beating" a phrase that seemed familiar to him. Rushing back to S.T.A.R Labs Barry passed out on the floor. Caitlin examined his injuries and told him he had various fractures, a concussion and a bruised spleen the injuries being so severe to the point that Caitlin told him even with his healing abilities it would take a couple hours for him to recover. Barry then told them about the meta-humans abilities. Barry then asked how he was gonna fight a man made of steel. Dr. Wells and the team assured that they would find a way. The next day Barry reported to the Central Police Department, where he confirmed with Joe that the metal man was indeed a meta-human. Joe told Barry that he was putting him and Eddie on the case so that Barry could explain to Eddie what he saw. Barry then went to see the Central City District Attorney. The DA identified the "man of steel" as Tony Woodward. Barry recognized the name. Woodward was a former classmate of Barry and Iris’, who bullied Barry throughout his childhood. After the meeting, Barry and Eddie ran into Iris. Eddie asks Barry what’s going on between Iris and him, not knowing that Barry was avoiding Iris but Barry told him everything was fine.

At S.T.A.R. Labs, Barry was introduced to a girder dummy built by Cisco so Barry can learn the right speed to take down Tony Woodward. Barry was easily defeated and dislocated his shoulder in the process. Shortly after, he was called by Eddie who had found the missing Humvee. Barry responded and as he arrived, Eddie recommended that he should get a car. Eddie then asked what's happening between him and Iris again where Barry revealed they had a fight. Barry and Eddie then headed to Rusty Iron Ale Brewing Co. after suspecting he had dropped by there due to the kegs in the trunk. After questioning a few men at the brewery, one man ran where Barry and Eddie chased him. Barry ran in front of the two, where the man punched Barry though it slowed him down enough for Eddie to take the man down. They then learn that Tony supposedly died in an accident though they revealed to the man that he lived. Barry visited Iris at Jitters again where he told her that Tony is an example of why she should stop blogging about him. As the cops arrived, Barry ran off to Tony's hideout. Barry was easily defeated by Tony and rendered unconscious. After he was brought back to S.T.A.R. Labs, he was yelled at by Harrison Wells who reminded him that they were still finding a way to stop him. Barry was then told that they had found a way to stop Tony and that is to hit him at 837 mph. At the precinct, Barry and Eddie discussed being victims of bullying as kids. While blowing off heat using a punching bag. They were soon told that Iris was missing where the two quickly rushed down. After learning a fire alarm went off at his old elementary school, he quickly realized that's where Tony and Iris were. Barry fought Tony but was once again defeated. Barry then ran away from the school, 5.3 miles exactly. Barry then ran back towards the school, breaking the sound barrier and knocked Tony down. Barry then greeted an incarcerated Tony, revealing his identity and told him that the particle accelerator made them who they truly were.

After walking away from the makeshift prison, Barry celebrated as he had finally had his revenge on Tony. Barry then greeted Iris at Jitters and the two reconcile. When Iris told Barry more about "The Streak", she told him how he comes and goes in the blink of en eye where Barry interrupted her saying he does it in "A Flash".

Barry went for an early morning coffee run at Jitters, though a trainee was working that morning. After a woman complained about it, Barry sped past and got everyone their coffee and left a large tip for the trainee. As he left Jitters, a man grabbed him and asked for his wallet. Barry laughed at the man, as he chose him out of everyone else in the city. Barry proceeded to take a majority of the mans clothes off and brought a police officer as he ran away. Barry later was called to a crime scene where a man was burned to death. Joe said Barry had to ID him though Eddie asked how Barry was going to do so with the mans face melted off. Barry then bragged about his "mad skills". Barry then brought the photo of the man to S.T.A.R. Labs, where they managed to ID the man as Casey Donahue. Shortly after, the mans ID was used at an electrical plant, which Barry quickly responded to. When Barry arrived, he encountered Farooq Gibran, a meta-human who has the ability to drain electricity. Barry made a few attempts to avoid his attacks though Barry was soon struck by Farooq. Barry later tried to run away, though to his surprise, he had last his super speed. At S.T.A.R. Labs, they had tested him on the treadmill, though to everyone's surprise, Barry ran slow for a normal person. Barry warned Barry about the meta-human who siphoned his abilities and killed the man. Barry later bumped into William Tockman at the precinct, who had complimented him for his watch. At S.T.A.R. Labs, they managed to identify the meta-human who shortly arrived at the lab, demanding to see Harrison Wells. Wells shortly told Barry that they could try jump starting him to regain his speed which Barry quickly agrees to. When Farooq broke into the lab, Barry tried to talk sense into him but Farooq only struck Barry. Cisco managed to close the doors to hold Farooq off for a short while. Barry and Caitlin then went to the treadmill to jump start his powers. When Cisco turned the power back on, Caitlin was hesitant to follow through as she was afraid he would die. Barry told Caitlin that if she doesn't follow through that they would all die. When Caitlin made an attempt to jump start Barry, though they would learn that it had failed. Barry and Caitlin then witness Tony get defeated by Farooq. Barry asked what he was doing outside of the prison where Tony reminded him he never steps away from a fight. Tony then told Barry and Caitlin to get out as Tony died. Barry was then furious at Harrison, who had used Tony to buy some time. They then noticed that Barry's cells were still regenerating though Barry still didn't have his speed. Cisco and Caitlin then believe he has yet to regain his speed is because it's mental and doesn't believe enough. When they made an attempt to escape the lab, they were attacked by Farooq. Harrison then finally faced Farooq.

When Farooq attacked Harrison, Barry finally believed enough to regain his speed and save Harrison. Barry faced Farooq once more but this time he has connected to his powers and the energy overwhelmed Farooq, killing him. Barry then rushed to the precinct, worrying that something had happened to Iris. He was relieved when he saw her safe in Joe's arms. After they locked up Farooq's body, Caitlin noticed that Barry's cells were regenerating faster than before. Barry payed Eddie a visit at the hospital. After Iris left to grab a coffee, Barry briefly left and had a conversation with Iris as the Flash. Barry then told Iris he would never be late again and that Iris is worth being on time for. Barry then ran off and returned to Eddie's hospital room.

Barry arrived at a bank that Roy Bivolo was robbing, only to find everyone attacking each other. Barry managed to save a man from being shot as everyone began to stop attacking. When Joe and a few other police arrive at the scene, Barry suggested to Joe that the people were "whammied". At the precinct, Barry learned that Eddie finally believed the Flash's existence though he learned Eddie believes he's a menace. Barry proceeded to steal Captain Singh's lunch as he went to S.T.A.R. Labs to discuss the new meta-human. Shortly after, Iris called him out through her blog. Before Barry left, Caitlin told him not to get involved in Iris and Eddie's relationship as he would be responsible for their breakup. When Barry arrived at Jitters, he told Iris his name was Ralph. Barry was warned by Iris that Eddie was pushing to get him behind bars. Barry managed to get to the storage facility Roy was hiding at before Joe and two other police officers could be killed. Barry was then greeted by Oliver, who had arrived in time to injure a "whammied" police officer. Barry then raced to the barn Oliver, Felicity, and Diggle were hiding at. When he arrived, he bragged how he gave Oliver a half an hour head start, yet still beat him. Barry asked the three what they were doing in Central City where he learned they were investigating a homicide which possibly connected to Central City, due to the material of the boomerang used to kill. Barry suggested that the two teams should work together, though Oliver refused as he didn't want anymore people in on his secret. Barry then carried Felicity and took her to S.T.A.R. Labs as she volunteered to go help. Barry was later told by Harrison and Joe not to trust Oliver as they feared he was too dangerous. The following day, Barry met up with Oliver and Felicity at CC Jitters, where Barry learned that Oliver had helped get the name of the meta-human. Barry was then asked by Iris how he knew Oliver Queen. She then sarcastically said that Oliver's arms were twice the size of his and told him that Oliver was on her top 3 cheat list. Barry was then glad when Oliver decided to work along with him. The following day, Barry arrived late for the training, despite his speed. Barry was told by Oliver that he always ran in blind and he has a lot to learn. Barry was told to run a distance and run back where he'd get shot by an arrow where Barry told Oliver he wasn't going to be shot. Barry proved him wrong by catching the arrow though he was struck in the back by 2 bolts which Oliver had set up. At the precinct, Barry was told once again not to trust The Arrow, though Barry defended him, saying he's the reason they had Bivolo's name. Barry then decided to cut off the partnership and go after Roy himself. Barry was whammied by Roy but he believed there was no effect on him. Barry proceeded to bring up Ronnie in front of Caitlin. He later met up with Oliver where he told him that he believed Oliver was jealous of him. At the precinct, Barry lashed out at Captain Singh. Later on, Barry attacked Eddie and threw him out of Iris' car. As he was about to beat Eddie, Barry was hit by a trick Arrow from Oliver. Barry then pulled the rope from the arrow and dragged Oliver down an alley. When Oliver fired two arrows, Barry dodged them, believing Oliver had missed, though he failed to realize there was an electricity box behind him. Oliver then injected Barry with two thousand milligrams of horse tranquilizer, though his metabolism burned it all off. Barry then ran circles around Oliver and as Oliver used one of his arrows to get on the roof, Barry reached the roof first and knocked Oliver down. Barry then dodged a few hits from Oliver before punching him several times. Barry then caught two arrows which Oliver had set up to his motorbike. Barry was then shot in the leg with a flechette and then held by Oliver as Joe and Harrison arrived to reverse the effects from Bivolo. Barry and Oliver went on to take down Bivolo and look him in the prison in S.T.A.R. Labs. The following day at Jitters, Barry apologized to Oliver for his actions and his words, but was then told by Oliver that guys like them can never get the girl because of what they do. Barry visited Iris at Jitters though he learned Captain Singh has called the task force to bring him in. Iris proceeded to tell him she doesn't want to see him again after what he did to Eddie. Barry then ran off into the night.

Barry arrived in time to intercept two boomerangs from striking Oliver. Barry ran to the arrow-cave and performed the salmon ladder at super speed in front of Caitlin and Felicity. Barry then stated the salmon ladder made him hungry for sushi, which he quickly grabbed before rushing back. When Barry returned to the arrowcave, he had blown his identity to Lyla Michaels, to who he thought was Diggle's wife. Barry offered to help with the case, though Oliver told him that things are a lot different. Barry told Oliver that he had begun to approach cases more carefully rather than just running into them. Oliver then accepted his help and told Barry they needed to reassemble the boomerangs to which Barry did swiftly. Barry and Oliver visited Quentin Lance where Quentin had forgotten has name and believed it to be "Bart." Quentin also believed that Barry was hit by a bus, rather than lightning, though Barry corrected Quentin. Barry asked Quentin about Klaus Markos where he learned enough information to track Klaus down. Barry was later surprised that Oliver was part of the Bratva, where Oliver told him that he's no longer a member. At the Bratva's hideout, Barry managed to subdue the members before Oliver arrived. After Oliver tortured Klaus, Barry brought Klaus to the Starling City Police Department and cuffed him to a drawer. When Barry returned, he admitted that he should have listened to Harrison Wells and Joe West. When Oliver told him that Starling City isn't always sunny and that he had friends and family murdered, Barry interrupted Oliver, saying he watched his mother get murdered also. Barry then told Oliver that he doesn't use his own personal tragedies to torture whoever pissed him off. When they believed they had tracked Digger Harkness, Barry and Oliver arrived at the warehouse, though they realized that they were played. When they returned, they found Lyla in critical condition where Barry rushed her to Starling General Hospital. After Oliver blamed himself, Barry reassured him it wasn't his fault. When Oliver told Barry that everything he had been through taken away his humanity, Barry told him his humanity is what got him through everything. Barry and Oliver arrived later arrived a the train station where they had tracked Digger. Digger told them that they can stop him, or 5 bombs from detonating. Barry left to defuse the bombs while Oliver dealt with Digger. When Barry arrived at the first bomb, the team quickly realized that the bombs are linked and if one is defused, the remaining will detonate. Cisco told Barry that he needed to cut all 5 wires at the same time though Barry reminded him he wasn't Multiplex. Barry then quickly grabbed Felicity, Caitlin, Roy, and Cisco to the other four bombs where the five of them managed to cut the wires simultaneously and stop the bombs from detonating. At the arrow-cave, Barry was surprised when he had a mannequin set up for a future team-up. When Oliver said he will still be calling the shots, Barry told him that they'll see about it. Barry and Oliver then went to a warehouse to settle once and for all, who would win in a fight. Before the dueled, Barry told Oliver that he could still inspire people, but as Oliver Queen. Barry managed to catch two arrows from Oliver before charging towards him and dodging multiple arrows.

Barry visited the West household for Christmas. When he set up the Christmas tree using his speed, he was told to remove what he had added as the only red suited man Joe wanted to see in the house was Kris Kringle. Iris shortly arrived with egg nog using her grandmother's famous recipe. Barry and Iris shortly exchange gifts where he gave Iris a replica of her mother's wedding band. Iris gave Barry a microscope which she thought was lame but Barry claimed he loved it. They were shortly interrupted by Eddie who joined them for tree trimming. Barry went to S.T.A.R. Labs where he brought the team gifts as well as Grandma Esther's eggnog. After an attack at Mercury Labs they discovered it was the work of the man in yellow. Barry quickly wanted to go after him but was told by Joe that the speedster took all the evidence and threatened to kill Iris. At the precinct, Barry had memories of the night as he looked upon his bulletin board. He was visited by Iris who had been calling his name multiple times. Iris told Barry that Eddie had asked her to move in and she said yes. She then asked if Barry had feelings for her as Eddie was under the influence that he liked her. Barry quickly denied the suggestion. As Iris left, Barry sulked to himself but moments later saw the man in yellow, the Reverse-Flash, watching him just across from the precinct. Barry chased after Reverse-Flash and begging to know why he killed his mother, but Reverse-Flash told him if he wanted to know he'd have to catch him. The two race down towards a stadium where they battled though Reverse-Flash quickly defeated Barry. Barry asked Reverse-Flash who he really was but the man claimed Barry already knew who he was, that they had been fighting each other for years. As Barry tries to fight back Reverse-Flash subdued him and told Barry it was his destiny to die at his hands, just like it was mother's. The following day, Barry told the team about what had happened. After Barry believed he couldn't catch him, Wells reminded that force fields are impervious to speed. Barry and Joe are visited by Tina McGee at the precinct who brought an unsigned warrant. Barry blackmailed Tina into giving them the tachyon prototype within the hour. Barry was then told by Barry that it's best for him to stay away while they capture the man in yellow. Barry argued that it's his fight though they still shut him down. Barry visited his father and told him that he had found the man who murdered Nora. When he apologized for failing to catch the man, his father reassured him that it wasn't his fault. Barry was then told to stop pursuing that man as everything that happened to Barry was influenced by the murder. His father noted that he had given up the chance to be with Iris because he was too consumed with what happened. His father then told Barry to not let the man take anymore from him. Barry then went to visit Iris and confess his feelings, leaving Iris in tears. Barry received a text from Caitlin that Reverse-Flash was attacking S.T.A.R. Labs. When Flash arrived he attacked Reverse-Flash though was quickly defeated again. Before Reverse-Flash can kill him however Flash is saved by a seemingly alive Ronnie who quickly fled shortly after. Back at the precinct, Barry and Joe recount the early days of Barry moving in. Joe claimed that Barry changed the atmosphere of the house and asked Barry to move back in. They then return to Joe's home for a Christmas gathering where he gave his best wishes to Eddie and Iris.

Upset he couldn't stop the Reverse-Flash in their last encounter, Barry trained harder. He had Cisco use a drone to fire ammunition at him, all of which he evaded. He then had Cisco fire a missile, which Barry successfully grabbed and threw towards the drone. Shortly after Snart re-emerged, Barry quickly realized Snart was setting a trap for the Flash. Barry vowed to take Snart down but Wells told Barry to set his priorities straight and focus on taking the Reverse Flash down. Barry went to Joe and told him he was going to focus on the Reverse-Flash and left Snart to Wells and Cisco, much to Joe's dismay. At S.T.A.R.L.A.B.S., after Caitlin brought up how Ronnie brought her scuba diving, Barry realized Firestorm wasn't a word but indeed an acronym. After Leonard Snart and Mick Rory steal the Fire & Ice painting from the Ratahway's, many of the CCPD were injured and Barry admitted to Joe he should've listened and focused on the current situation. Wells apologized to Barry for pushing him to focus on the Reverse-Flash but Barry told Wells he made the decision on his own. After Snart and Rory made their public address to the Flash, Barry goes after them, making himself public for the first time. Though Snart and Rory get the upper hand at first, Barry realized in order to cancel the two's weapons out, he had to move slower. When Leonard told Barry he won this time, Barry responded that there won't be a next time. The following day, after Iris had moved out, Barry moved back in with Joe.

With the assistance of his team, Barry took down the Royal Flush Gang with ease. When he returned to S.T.A.R. Labs, the team took a group photo. After Wells was attacked by Hartley Rathaway, Barry went over to his mansion. When he noticed the shatter of the glass, he realized it couldn't have been a teenage prank. At his lab at CCPD, Barry demonstrated how Hartley likely used some sonic technology when he attacked Wells. After Eddie reported an attack on Rathaway Industries, Caitlin called Barry but Barry told Caitlin he already knew why she was calling. Barry quickly took down Rathaway, who told Barry he can hear Cisco, Caitlin, and Wells through the radio waves. After Wells admitted he knew the chance of failure of the particle accelerator, Barry told Wells he owed Caitlin and Cisco more than an apology, as they stuck around when everyone abandoned him. Later that night, Barry and Iris had a coffee at Jitters discussing how people they admire aren't who they seem to be. When Hartley broke out of the prison, Barry rushed to S.T.A.R. Labs though Hartley had left by then. When Hartley attacked the Keystone Cleveland Dam, Barry rushed over and arrived in time to save a woman who Hartley threw off. Hartley used the data on Barry's molecular scans to stop Barry once he was disarmed. Hartley was then stopped after the team hacked into the frequencies after the cars at the dam to send out waves powerful enough to stop Hartley. When Wells told Barry he wished to regain the trust of the team one day, Barry told him he already had.

Barry saved a couple from a burning car, Cisco told Barry he couldn't be mad for dirtying his suit, to which Barry asked when he could start calling it "his" suit. While Barry was investigating Clay Parker, he was greeted by his father. When Barry brought the DNA samples to S.T.A.R. Labs, they realized Shawna Baez was also involved. Barry and Caitlin discuss how they both don't have much of a social life where they were interrupted with a sighting of Shawna Baez and Clay Parker. Barry rushed to the scene and was shocked when he learned Shawna can teleport. He was shot at in the neck by Clay Parker but managed to stop the bullet, though the two escaped. Barry stopped by to help Iris with a report, though she already had plans with Eddie. Barry then decided to drop by a south-side dive bar with Caitlin to check if Shawna and Clay returned to old habits. After Caitlin had a few drinks, she walked up to the stage drunk and called Barry out to join her. The two then sang "Summer Nights" where Caitlin was shocked Barry could sing well. After their duet, Barry was greeted by Linda Park, who offered him her phone number. Barry then took Caitlin back to her apartment and put her to bed. The following day, Barry teased at Caitlin for what happened the night before. Barry was called and told that his father was beaten by Julius. Barry asked who attacked him and went after Julius. Barry broke Julius out and told him he wouldn't return him to prison, causing him to face more time if he didn't give him Clay and Shawna's next heist. After Barry was told they were in St. Louis, Barry decided to leave Julius out for beating his father. While chasing Clay and Shawna, Barry busts out all the lights in the tunnel they were in, disabling Shawna's teleportation abilities and locking her in a one way glass. Later, Barry decided to call Linda Park and asked her to go on a date. Barry gave Iris information on Clay Parker to use for a report for the Central City Picture News. He then picked Linda up and the two go for a date. That night, Barry went back to Iron Heights to check on his dad. When Henry began putting the pieces together that Barry was the Flash, Barry claimed he would've told his dad if he was the Flash. Barry was then told that the world is dangerous and told to be careful and that his father was proud of him for saving many lives.

Barry took Linda on a dinner date at a Mexican restaurant. While Linda went to wash her hands, Barry was notified of a robbery at a convenient store and quickly settled the robbery. The following day, Barry had another date with Linda but had to end the date early after Wells and Caitlin spotted Firestorm. Barry tried to stop Firestorm and told him they could help but Firestorm attacked Barry and flew off. Barry and Caitlin then tried a different approach, bring Martin Stein's wife along this time, which Martin finally agreed to get help. Linda called Barry to break up with him as she felt he didn't care enough in the relationship as he often ran off and made excuses. Linda told Barry that it's hard to date someone new when you aren't over someone and understood. Barry went to ask Iris why she told Linda she had feelings for her still and told Iris he no longer had feelings for her. At S.T.A.R. Labs, the team learn that Ronnie and Martin could go nuclear and level the entire city, unless the host body was killed. Barry went to offer Ronnie/Martin some pleasantries though Ronnie told Barry he overheard the conversation. Barry went to Central City Picture News and told Linda he was going to eat a ghost pepper if she didn't agree on another date. Barry took a bite after she believed he was bluffing and Linda agreed to go on another date and offered him some milk. Barry returned to S.T.A.R. Labs and the team decide to use a quantum splicer on them two separate but learn Martin had left already. Barry and Caitlin rush over to Martin and the two told Martin that they have a way to separate them. After the quantum splicer was placed, Firestorm reacting, believing they had failed, Barry grabbed Caitlin and ran off to safety as an explosion set off.

After they got to safety, Caitlin worried they were exposed to radiation, though Cisco informed them there were none. They went back and were pleased when they learned they successfully separated and took them back to S.T.A.R. Labs. Barry was contacted by Joe and was informed what he learned with Cisco the previous day. They brought the news to Wells who told them time travel is indeed possible. Barry then went to ask more about time travel with Martin Stein who suddenly had a panic attack when General Eiling attacked CC Jitters. Barry rushed over to stop Eiling but the latter used kinetic needles to stop Barry. They later learn that Martin and Ronnie are still connected. At his home, Barry asked how Joe knew who's blood sample to match and was told that Joe asked Cisco to match the sample with everyone who worked at S.T.A.R. Labs. Barry then told Joe to not worry as he was sure Wells had nothing to do with his mothers murder. After Martin was captured, the team track him down and Barry, along with Ronnie go to rescue Martin. Barry was hit with a weaponized phosphorous and began running in circles to burn it off. After Eiling had the upper hand, he prepared to kill Firestorm though Barry stopped Eiling in time and Barry returned to S.T.A.R. Labs with Firestorm. Later, Barry told Joe that when the time came, he wouldn't fail like he believed he had in the past and he would save his mother.

After Barry loses a USB drive containing information on various crime scenes and searches for it at S.T.A.R. Labs with little success, but his attention was quickly diverted when Cisco told him of a possible metahuman, Mari McCabe whom Cisco nicknames “Vixen”. However Cisco also informs Barry that Mari was currently living in Detroit and not knowing what to expect Barry went to Oliver for help and the two headed to Detroit to confirm whether or not she is a threat. Flash and Arrow arrived at the house of Mari’s foster father Chuck but when she saw the vigilantes she immediately ran and they gave chase. Flash gave chase to Mari whose speed was just as fast as his and asked her to stop but she refused and displayed incredible strength caused Flash to fly back several blocks, but eventually resumed the chase with Arrow. Mari then displayed the ability to run up a building forcing Flash and Arrow to take the fight to the rooftops. Despite the combined efforts Mari continued to outrun Flash and dodge Arrow’s shots, even crushing his arrows with her bare hands. Mari also displayed the ability to camouflage but Arrow attempted to restrain her with a jettisoning arrow but she outran it, only to slip off the side of the building but then displayed the ability of flight which highly impressed Flash. As Mari attempted to fly away Arrow convinced her to come back as they just wanted to talk, though Flash wanted to handle the talking claiming to be better at it but Arrow simply reminded him he just puts meta-humans in the pipeline. However Mari shot down Flash and Arrow’s claim that she was a meta-human claiming that she wasn’t in Central City when the particle accelerator exploded, which Felicity was able to confirm. Though Flash was unconvinced Arrow offered their help to Mari to understand what she can do but she turned them down as she was uninterested and warned them that if they ever showed up at Chuck's house again, she’d kill them and flew off.

Ignoring Mari's warning Flash and Arrow returned later to her house, where they discovered she'd become a vigilante herself, and Arrow questioned her intentions to take on Detroit's criminals without training. However Mari convinced them to let her try things her way for a while and Arrow agreed and wished her luck as Flash reminded her they could still help if she needed them to. After Mari asked if they had an idea of a name for her Flash told her that Cisco had been calling her Vixen, and he quickly tried to cover up mentioning Cisco causing Arrow to ask if Barry and Felicity were separated at birth. Arrow also learned that Flash kissed her causing him to speed off in worry.

Barry took Linda bowling where they bumped into Iris and Eddie. The two join them but later, Eddie and Barry were called after a silent alarm went off at the Central City Morgue. Barry ran ahead and investigated the crime scene prior to returning as his CSI job and on his way, he noticed another Flash running beside him. After listening to a recording, they learned that it was Mark Mardon who attacked the Morgue. The following day, while Barry and Joe were discussing over a drive, they were attacked by Mark Mardon, though Barry got Joe to safety in time. Barry and Iris later went to CC Jitters where the latter told Barry that she suspects Wells had to do with Stagg's murder. Barry told Iris that Wells is a great man and she won't find such a story. Barry later told Cisco and Caitlin from what he heard from Iris but still denied the fact that Wells had involvement in Stagg's disappearance. After Mark attacked the precinct, Barry ran over in time to stop Mardon with the Wizard's Wand, though Mark escaped. The following day, Barry dropped by and conversed with Mason Bridge about Harrison Wells. Barry asked Mason what evidence he had on Wells and was told to read about it like everyone else. After Joe was kidnapped and held hostage by Mark Mardon, the latter called Iris to meet him at the waterfront. Barry went to help Iris. Linda stopped by the precinct to talk to Barry, though Barry told Linda there was something more important, though not what she thought was going on. At the waterfront, realizing the danger, Barry told Iris to get out and get to safety, though Iris confessed her love for Barry. The two share a kiss before Barry revealed his alter-ego to Iris. To stop Mark Mardon's wave from destroying the city, Barry ran back and fourth the seawall to create a barrier of wind and doing so, he accidentally traveled back in time as he watched his past self run towards the morgue.

At the morgue, Barry was confused at what was going on, quickly solving everything. At S.T.A.R. Labs, Barry finished off everyone's sentences and Wells quickly realized that Barry had traveled back in time. Wells then warned Barry to not alter any events, big or small as it could cause a cataclysm. Ignoring Wells instructions, Barry tracked down Mark Mardon and brought him to the S.T.A.R. Labs particle accelerator prison. Wells told Barry that even though he may have saved many lives, time would find a way to repair itself. Barry ran as fast as he did previously in an attempt to go back once again, though to no success. At Central City Picture News, Linda told Barry that she knows he still had feelings for Iris and broke up with him, though wished him luck with Iris. Barry then told Mason he knew he suspected something wrong with Wells. Later that night, Barry and Cisco grab a drink but Barry ended up leaving Cisco with Lisa, unknown to him who she really is. The following day, Barry confessed his feelings to Iris, though to his surprise, she didn't feel the same way. After a report of Snart and the Santini crime family casino, Barry rushed over and held Lisa hostage. Snart told Barry to let her go as he told Barry he has Cisco hostage. After the two left, Barry returned to the labs as a CSI where he was punched by Eddie for trying to win Iris over earlier. The following day, Cisco showed up at S.T.A.R. Labs and quit, feeling guilt for revealing Barry's identity. Barry told Cisco that he shouldn't feel sorry but Cisco still felt the guilt. Barry and Caitlin later realize the casino wasn't the target but a way to trigger a money transfer. Barry chased after Leonard, Lisa, and Mick and captured Leonard. Barry told Leonard he could lock him up for good but Leonard told him then there would be no way of stopping his broadcast of him revealing Barry's identity. Barry told Leonard that if he was good as he claimed he is, he shouldn't need to kill. Barry then told Leonard if he hurt anyone close to him, he would go after him, no matter who Leonard told his secret to. At Jitters, Eddie apologized to Barry for hitting him and learned that Caitlin told Iris and Eddie about his "lightning psychosis". Barry later went to ask Wells about Stagg but before he could ask, he saw a report of Mason Bridge missing. He later called Joe and admitted that he was right about Wells.

Discovering Wells' true identity
Barry and Joe discuss over Wells and while Barry believed he could be the Reverse-Flash, Joe told Barry that the blood at the house didn't match his. Barry then rushed over to a terrorist attack by Axel Walker, who claimed himself as the Trickster. They learn that Axel is a copy cat of James Jesse, who had killed 10 civilians and 2 cops prior and now facing life sentences at Iron Heights. Barry and Joe head over to Iron Heights where James Jesse told them Axel likely found his lair. On their way out, Barry stopped by his fathers cell and told him he has gotten closer than he had before in investigating his mothers mother. Iris later called the Flash to ask for help for the investigation on Mason Bridge's disappearance. Axel then made an address that he had planted a bomb somewhere in Central City. When Barry couldn't find the bomb, Wells told him it was a trick but Barry refused to listen. As Barry kept looking, Wells theory was indeed correct as Axel broke James Jesse out and took Henry Allen hostage. Upset his father is held hostage and possibly killed, Joe was comforted by Barry and while the latter no longer trusted Wells, Joe told Barry it didn't matter why Wells was helping and the only thing that mattered was that he did. After they tracked down the Tricksters, Barry ran over but Axel planted a kinetic bomb so if Barry didn't run over 600 mph, the bomb would go off. Barry was told by Wells to phase through a wall but Barry refused to listen. Wells told Barry to feel the power and electricity and that he was now part of a speed force. Barry ran through a truck, getting the kinetic bomb off and returned to City Hall to give everyone an antidote. Barry then went to rescue his father before knives could drop on him. Barry then confirmed his fathers prediction that he is indeed the Flash. At S.T.A.R. Labs, Henry thanked Wells for taking care of Barry, though Barry didn't seem to happy. The two share a hug before Henry was brought back to Iron Heights. At the precinct, Barry revealed his identity to Eddie and told Eddie to get Iris to stop looking in on Mason Bridge. Barry then described Wells' speech and deduced that he is indeed the Reverse-Flash.

Barry, Eddie, and Joe quickly took down a group of robbers and apprehended them. The following day, they went to Hudson University where Lindsay Kang was stung to death. Barry brought a sample back to S.T.A.R. Labs and they were soon joined by Felicity and Ray Palmer, though Barry told Felicity it wasn't the best time for a visit. At Jitters, Barry and Felicity were interrupted by Eddie and the three ended up making dinner plans between Eddie, Felicity, Barry, Ray, and Iris. Soon after, Bill Carlisle was attacked at Folston Tech but Barry was too late by the time he got there. He was then attacked by Brie Larvan's bee's and went unconscious. With a defibrillator Cisco built in, the team regained Barry's consciousness. Later that night at the dinner, Barry informed Felicity who Wells really is after Ray discussed how Wells was his personal hero. After things at dinner went downhill with Eddie and Iris, Barry was called back to S.T.A.R. Labs where they learned the bee's were all robotic. At Jitters, Felicity told Barry to inform Caitlin and Cisco about Wells, though Barry told Felicity it could backfire. Barry later told Iris to trust Eddie and that Eddie only wants to keep her in the light. The team later learned Brie went to her next target, Tina McGee and Barry went to Brie's hideout while Ray went to save Tina. Brie sent bee's to attack Barry but Felicity hacked into the software and shut the bee's down and restrained Brie. Barry rushed over to Cisco after he was stung by a bee and vibrated his hand to use as a defibrillator.

After Tina thanked Barry for the help, Barry asked what happened between her and Wells and learned one day Wells became a completely different person. Barry later called Caitlin and Cisco over and told them about why he and Joe had learned about Wells. When Caitlin was hesitant to believe them, Cisco told them he has had dreams of Wells murdering him.

Barry ran over to Coast City and returned to Central City with pizza. At Joe's house, they inform the rest of the team that Joe and Cisco are headed to Starling City to investigate Wells. Later, Eddie called Barry when there was a report of a male who was trying to sell jewelry which was stolen the night before. Barry rushed over but learned the man was a shape-shifting meta-human. When the team feared the meta-human could copy Barry's powers, they told him to keep hid hands off him. When Caitlin went to Wells' mansion, Barry rushed over and took her away and told her not to tell Wells anything. Eddie and Barry went to contact Mrs. Bates though soon realize it was actually Hannibal Bates. After Hannibal framed Eddie, Barry ran Eddie out of the precinct and told him S.T.A.R. Labs could keep him off the grid until they cleared his name but Eddie told him to do it the right way and Barry returned him to the precinct. Barry later got a visit from Eddie and was told Captain Singh called in a favor. As Barry turned his back, Eddie, who actually was Hannibal, hit Barry and hid him. Barry was later found by Caitlin and they return to S.T.A.R. Labs. Caitlin presented Barry with a serum which could disable his shape-shifting abilities. They then got a ping from Barry's phone at the airport and Barry ran over. Barry quickly spotted Hannibal and the two quickly fought before Hannibal was shot with the serum. Barry later gave DA Cecil a full list of everyone Hannibal had impersonated. Later, Joe and Cisco presented with their discovery in Starling City, the corpse of the real Harrison Wells. Upon seeing this Barry realized that Tina's words about Wells being a different person were true as the "Wells" they knew was an impostor. While Cisco was looking through the schematics of S.T.A.R. Labs, they spotted a hidden room. As they entered the room, they saw the Reverse-Flash suit as well as an article from 2024 reporting the disappearance of the Flash.

They realized that "Wells" was from the future. Barry, Caitlin, and Cisco were then greeted by Gideon who told Barry of his future. Barry, hoping to get some information out of it asked why Wells came to this timeline. Gideon revealed the grim, cold-hard truth: he came here to kill Barry. When they learn Wells was on his way, Barry quickly asked why he killed Nora Allen that night, where Gideon revealed that he did so out of anger after Barry escaped from him. When Wells was heading to the Time Vault, they quickly left. The team then help Cisco see his "dream" properly by constructing glasses that allowed lucid dreaming. At the precinct, Eddie asked Barry to ask Joe why he did not give his blessing for his proposal to Iris. Later, while Cisco was in his lucid dream, the team learned Wells' true identity, Eobard Thawne, who called them shortly after Cisco woke up. Eobard told him of a fire that just broke out and Barry rushed over. When Barry was unsure what to do, Eobard guided him to use his arms like a vacuum by rotating them fast enough. Later, Eobard told Barry that the only thing stopping him from achieving his goals, 9s himself. Barry later told Joe that they need to recreate the events that happened in Cisco's dream. At S.T.A.R. Labs, Cisco had rigged the force field so instead of keeping a speedster in, it kept them out, which Barry had tested. Later, when Eobard returned from his lecture, Eobard managed to enter the force-field. As he prepared to kill Cisco, Joe fired three bullets at him, though Barry stopped most of them. The final one Barry was unable to reach and Eobard was shot and killed. Barry was upset that Eobard would never be able to confess however, it turned out to be Hannibal Bates. They were then reminded by Eobard that he was always one step ahead. Barry told Eobard he could kill him if he'd just let his father out but Eobard told Barry he needed Barry alive. Cisco got a ping from Eobard's time vault and Barry ran over. Barry learned Eobard had camera's everywhere and had access to CCTV footage. Barry warned the team before running over to save Eddie and Iris. Eobard captured Eddie as Barry arrived. Barry told Iris everything was going to be ok and swore that he would bring Eddie home. As he ran off, Barry sent a static shock, much like he had when he was in a coma as Iris realized who the Flash really is.

Barry looked everywhere for Eddie but to no success. When Captain Singh asked where Eddie was, Barry and Joe told Eddie was taking personal time off. When the gold reserve was being attacked by Grodd, who had controlled Eiling, Barry ran over but was quickly stopped as Grodd "whammied" both Eiling and Barry. Back at S.T.A.R. Labs, the team was greeted by Iris, much to the teams shock. Barry explained to Iris that there had been many times he wanted to tell Iris his secret but learned that Joe was right. Barry and the CCPD later set a trap and capture Eiling. They locked him in the meta-human prison and learn he was controlled by Grodd. With the help of Iris, they learn of sewer workers going missing and Barry, Joe, and Cisco headed down to look for Grodd. Barry was whammied and knocked unconscious and Joe was kidnapped by Grodd. Later, Barry had Cisco build a tech so Grodd couldn't get into his head again. When Iris told Barry that he had been lying to her on the things that mattered most, Barry told Iris she had been lying about her feelings for him also. Barry cut himself off when he realized he couldn't have told Iris about the other timeline. Barry went 5.3 miles away from Grodd and ran toward him in an attempt for a super-sonic punch, though he had failed as Grodd cut his distance down. Grodd threw Barry on a train track and as Barry's tech broke, Grodd had gotten into Barry's mind once again. As a train went toward Barry, Iris told Barry that he could defeat Grodd and save Joe. Inspired by Iris' words, Barry got out of the tracks on time and as the train passed, challenged Grodd. As Grodd jumped toward him, Barry got out of the way and another train passed and hit Grodd. Barry saved Joe and freed Eiling from the meta-human prison. Barry later told Iris that it's the thought of her that always kept him going. Iris then told Barry that she did have feelings for Barry but Eddie is her boyfriend and missing. Barry then told Iris that he would do the best he could to bring him back.

After continuously searching, Barry told Iris he has yet to still find Eddie but promised he was trying his best. Barry was then called by Cisco who had learned Eobard had been using his wheelchair to absorb Barry's speed. When they learned the particle accelerator was turned on, they realize the reason they couldn't find Eddie and Eobard was because Eobard was holding Eddie hostage at S.T.A.R. Labs. When they opened the particle accelerator, Eobard escaped and Barry chased after him, though Eobard had gotten away. Later Barry apologized to Eddie for not finding him sooner. Barry said they needed to get the meta-humans out as though they are dangerous, they don't deserve to die. Barry suggested they transfer them to the super-max on Lian Yu. Desperate, Barry looked to Leonard Snart to help transfer the meta-humans, under one condition, Barry erase all criminal records of him, though Joe was very disappointed Barry looked to such lengths. They had the meta-humans placed in a truck owned by Cisco's family and used the device from Eobard's wheelchair to disable the meta-humans powers temporarily. Once they reached the hangar, the meta-humans had escaped and began attacking Barry, Cisco, Caitlin, and Joe. They then learned it was Leonard who had sabotaged the truck and let the meta-humans escape. Leonard told Barry he had done so as they all now owe him and could be useful as a part of his Rogues Gallery. When Barry asked why he had spared him, Leonard told him he now owes him as well.

At S.T.A.R. Labs, Barry felt guilt having his plan failed and wondered how Oliver could do whatever it took to get what he needed. The particle accelerator then was fully charged and online. Eobard approached S.T.A.R. Labs and Barry ran out to face him. Eobard told Barry he couldn't stop him if he had tried as Eobard was always faster. Barry was then joined by Firestorm and Oliver. Barry and Eobard faced off as Oliver tried to get a clear shot at Eobard. Barry was thrown towards a S.T.A.R. Labs sign and as Eobard used his hands as a vacuum to blow Firestorm away, Barry ran over to grab Firestorm. Barry ran back and stopped Eobard before he could kill Oliver. Barry and Eobard fought on the roof of S.T.A.R. Labs and Eobard was thrown off S.T.A.R. Labs by Firestorm.Eobard was then shot by Oliver with another nanite arrow, disabling Eobards speed and making him unconscious. Barry thanked Oliver and Firestorm for their help and looked over Eobard, finally taking down the man who murdered his mother. Barry ran off to Nanda Parbat and freed Oliver's friends. When Felicity asked to help save Starling City, Barry said he had a long overdue conversation with Eobard.

Barry asked why Eobard he murdered his mother, Eobard told him he hates him for something future Barry had done. He reveals that killing Nora was not his original intention, as he really went back 15 years to kill Barry when he was still a child. When Barry got his past self to safety, Thawne was so angry that he took it out on Nora by killing her. Eobard then told both of them could get what they want, Barry return to save his mother which would allow Eobard to return to his time. Barry presented this information to the team who all agreed he should do so. Barry asked Joe why he was so supportive and Joe told him though he had been a great son, he wants Barry growing up with his mother and his real father. Barry told his father he could save his mother but Henry told him it was to dangerous due to the repercussions of time travel. Iris told Barry she knew of a possible future of them being married in the future and joked she was never a fan of hyphenated names. Eobard explained how Barry was going to go back to the night his mother was murdered, he warned Barry that he could die if he didn't reach the right velocity. Later, Barry was informed that as well as dying, Barry could cause a singularity which could destroy earth and continue even after the earth is gone. Barry along with the rest of the team attended Ronnie and Caitlin's wedding before Barry prepared to save his mother. Barry said his goodbye's to his friends and foster family. Barry was then told he had 1:52 seconds otherwise a singularity would form. Eobard told Barry he holds both of their futures and then told him to run. As Barry ran, he saw the past, present, and future before traveling back to the night his mother was murdered. When Barry arrived to the night, Barry looked on as his future self battled Eobard. His future self then signaled him to stay back and Barry looked away as his future self rescued his younger self and Eobard murdered his mother. When Eobard had left, he went and told his mother that he and his father turned out to be ok. His mother looked at him, proud of her son, and Barry tells her goodbye, before she dies in front of him, her last words being "Goodbye, Barry."

Barry returned and broke Eobard's time machine. Eobard asked why he didn't save his mother and have everything he had wanted and Barry told Eobard he already has. Barry and Eobard battled though Eobard quickly has the upper hand. When Eobard told he was going to kill as his friends and family, Eddie shot himself and Eobard fell back. Cisco quickly realized that Eobard was being erased from existence and before Eobard vanished, Eobard told Barry he controlled his life all his life and wondered how he would go on without him. A singularity formed in the particle accelerator and the team rushed out. As they watched the singularity eat Central City, Barry told the team he had to try and stop it, even with little chance of success. Barry ran through Central City and jumped towards the singularity. As he stabilized the singularity, Firestorm flew toward the singularity and Barry watched as the two separate, causing the singularity to close. As Martin Stein plummeted to the ground, Barry caught him. When Caitlin arrived at their location and learned Ronnie didn't make it, Barry hugged Caitlin and looked toward the sky. For the next six months, Barry lived in solitude, blaming Eddie and Ronnie's deaths on himself.

Going Solo
Eobard Thawne, as Harrison Wells left S.T.A.R. Labs to Barry in his will, yet six months after the issue with the singularity, Barry had still not dealt with the mail he'd been getting regarding the property.

Flash Day
Barry investigated the crime scene involving the death of Al Rothstein. Barry identified that Rothstein was strangled by someone large, though assured Joe that it wasn't Grodd. That night, Barry cleaned up Jitters from the destruction caused by the singularity. Iris arrived and joked Barry should be a contractor, as she noticed night after night, buildings had been rebuilt. Barry told Iris he wasn't going to his rally, though Iris told him he should just go as the citizens of Central City deserve to see the man who saved the city. Barry then told Iris that he wasn't the man who saved the city. After Iris left, Barry remembered it was Firestorm who closed the singularity, causing the death of Ronnie Raymond. The following day during his rally, Barry decided to show and accept the key to the city, much to the cities joy. As the key was handed over, Atom-Smasher threw a grill toward the mayor, though Barry got the mayor away in time. After Atom-Smasher grew, the Flash picked up and threw two propane tanks for Joe to shoot. After the tanks exploded, Atom-Smasher shrank and his mask unfolded. Barry and Joe noticed that he resembled Al Rothstein and Atom-Smasher fled. Later at the precinct, Greg Turk from Weathersby & Stone LLP gave Eobard's last will on a USB, stating it was meant for only him to view. Barry then had an alert of unauthorized entry in S.T.A.R. Labs, only to learn it was his team in the building. Barry told his team he didn't want them there, though he was told by Joe that he needed his friends. After Atom-Smasher was tracker, Barry ran out with his Flash suit, leaving the communication system behind. After landing a few hits on Atom-Smasher, the latter grew and strangled Barry with ease. After Cisco caused a distraction setting off the alarms, Barry managed to escape and run back to S.T.A.R. Labs, though he passed on soon after. When he woke up, Joe told Barry that he can't blame himself on the death of Eddie and Ronnie and that it was on the entire team. Barry then went to Caitlin to apologize for not saving Ronnie, though Caitlin told Barry it was her fault as at one point, Ronnie asked her to get away from Central City, though she refused. Barry and Caitlin then watched Eobard's last will, where he confessed to murdering Nora.

Barry and Caitlin return to S.T.A.R. Labs and the former told the team he realized that the only way to stop Atom-Smasher was as a team. Barry attracted Atom-Smasher with a Flash signal. Barry had Atom-Smasher chase him to a local plant, where the former trapped the latter in an enclosed room, forcing Atom-Smasher to absorb more radiation than he could. Barry asked Atom-Smasher why he wanted to kill him and Atom-Smasher told Barry a man named Zoom would've brought him home if he killed him. Later, Barry then greeted his father at Iron Heights and brought him to Joe West's home, where Henry was greeted with a surprise party. Barry pulled his father aside to discuss future plans, though his father told him they can't live a life together as he didn't want to get in the way of his son being a hero.

Meeting "Jay Garrick"
At S.T.A.R. Labs, Barry was told on the increased security, where they were interrupted by Jay Garrick who warned them on an oncoming danger in the form of the evil Speed Demon named Zoom. Barry was told by Jay that when the singularity formed, it created a breach between both their worlds. Barry was then told by Jay that he was the Flash of his world. Jay told the team that he lost his powers and Barry quickly asked Jay how he lost them. Barry then told the team to do tests on Jay, warning the latter if he could have more enemies if they learn what he said was false.

Barry later discussed with the team that nothing Jay said added up. Martin Stein then presented the team with the multiverse theory, telling them they need to find the breach and close it. Barry was later told by Caitlin that she ran a lie detector test while testing Jay and he passed it. Barry still reluctant to believe Jay, told Caitlin to continue running tests. Barry locked "Jay" in the meta-human prison and was told by the latter that he only wants to help, not harm. Barry was then told by Cisco about a fire and Barry ran off to extinguish it. Soon after he extinguished the fire, he was attacked by Eddie Slick. Barry went to tackle Eddie but Slick got away with his powers. The following day, Barry returned the scene as part of his job. Barry deduced that the fire was from an arsonist and was then greeted by Patty Spivot, who claimed to be a big fan of his due to his forensic reports. Patty told Barry she'd been trying to crack Joe's "no-code" and asked for any advice as she knew Barry grew up with Joe as his father. Barry told that it was unfortunate as he'd been trying to pick that since he was 11. Later, Barry told Patty he would try to put in a good word for her.

Joe told Barry that the Eddie Slick they have in custody is proven innocent. Joe asked if it was possible if the Slick that started the fire was from Earth Two. Despite evidence piecing together, Barry told the team he still refused to trust Jay. When Cisco said Jay was right about Zoom, Barry reminded Cisco that they don't even know anything about Zoom. After Barry told the team they need to be extra careful, Iris pulled him aside. Iris told Barry she knew he's only being extra-cautious was because of Eobard Thawne. Iris reminded Barry that not everyone is the same and he only was able to beat him because he trusted in others. After Eddie Slick took Patty Spivot hostage, Barry looked to Jay for help. Jay told the only way he could stop Slick was by hurling lightning at him, as lightning and sand creates glass. For an hour, Barry ran in circles and hurled lightning at a dummy, with Jay continuously telling him to go slower so he could direct the lightning accurately. Cisco and Martin Stein then reported the two on Slick's whereabouts. Barry then told Jay that they could distract Slick, with Jay, as Slick is unaware Jay lost his powers. The team return Jay Garrick's helmet and the two Flash's join hands before leaving to rescue Patty. While Jay distracted Slick, Barry saved Patty from a concussion bomb. When Slick grabbed "Jay" by the throat, Barry ran in circles around Slick and successfully hurled lightning toward Slick, turning him into glass and shattering. Later, Barry apologized to Jay for not trusting him because of a former mentor. Later, Martin Stein told the team that the most significant breach was in S.T.A.R. Labs but shortly after, Martin collapsed.

Snart Family Issues
While doing forensic work at the Central City Police Department, Barry was called by Iris, who was at Baldwin Tower investigating a real-estate scam. Barry told Iris to jump out the window as Barry ran over to catch her. As Barry got Iris to safety, Barry ran back to the tower and subdued the two men. At S.T.A.R. Labs, Barry and the team investigated the wormhole in the basement. Barry was told that they've tried sending objects in but they've all jumped back. Barry told the team Zoom may have been able to cross worlds due to him being a speedster and Barry man an attempt to cross the breach. Unfortunately, Barry bounced back like the objects. The team deduced there's a hallway between the portals which continuously moves, therefore they need to create a "Speed cannon". Martin then told the team that they should all rest for the day. The following day at the grand-reopening of CC Jitters, Barry was shocked when he learned a beverage was named after him. Barry ran into Patty and they briefly conversed. Lisa Snart then bumped into the team, asking Cisco for the Flash's help as her brother was kidnapped. At S.T.A.R. Labs, the Flash asked Lisa why they should trust her due to them previously double-crossing them. When Cisco tracked Snart, the Flash told Lisa that they would see if she was lying and ran off. When Barry arrived, he found Snart, though he seemed fine. When Barry told Snart that his sister thinks he's kidnapped, Snart froze him. Barry was then introduced to Snart's father, as the two left. Cisco then used the thermal-threading he used on Barry's new suit to melt the ice. Barry returned to S.T.A.R. Labs and told Lisa that Leonard wasn't kidnapped and was doing work with their father. When the team asked why they should trust her for a final time, Lisa showed them a scar that was given to her by her father. Barry approached Leonard at a bar and asked why he was working with a man he despised. Barry was told things were complicated but Barry asked what was wrong so he could help. Barry told Snart that he may have a code of honor now but his father doesn't, leaving no choice but to stop the two. Snart reminded Barry that he could still reveal his secret and left Barry to pay for his bill. Later, Barry was told by Joe that lied about his wife as she never died. Barry assured Joe that it was for the best as Iris may have gone down the wrong path with Francine West, giving Leonard Snart as an example. Barry then told Joe that he should still tell Iris the truth. The following day, Barry, Joe, and Patty investigate a body that was decapitated. Patty asked if it could've been by a meta-human but Barry told her it wasn't. Barry then quickly discovered that Leonard is only working for his father as Lewis had planted thermite in Lisa. Barry contacted the team, who discover Lisa was indeed injected with thermite. When Barry and Caitlin search for the thermite with a magnet, Cisco told them to stop as the magnet cut set off the thermite. While Cisco told the team he would search for a way to extract the thermite, Barry told the team he should volunteer to replace Lewis Snart's new tech guy. Barry met with Leonard and told him of his plan. When their father arrived, Barry introduced himself as "Sam" and volunteered to join the team. To prove himself, Barry told Lewis that he helped his son steal the Khandaq Dynasty Diamond the previous year. Barry, Lewis, and Leonard arrive for a heist. When their ID's were failing, Barry told the security guards they should let them go before the managers start making complaints about the clogged toilers. When they arrived at the twenty-seventh floor, they find two security guards and Barry ran to subdue them as Leonard and Lewis argued. After Barry hacked into the security lock, Lewis fired a bullet at Barry, though Barry caught the bullet and faked being shot. Before Lewis and Leonard could get away, Barry intervened. Lewis told Leonard to fire his cold gun at him or Lisa dies. Barry told Lewis that the bomb was extracted by Lisa and Barry was then shocked when Leonard killed his father. As Leonard looked over his father, Barry took Leonard's cold gun, leaving him to be arrested. Barry payed a visit to Leonard at Iron Heights, telling him that he has good inside of him. As Barry left Iron Heights, he was told by Joe that the latter took his advice on told Iris of Francine. At Jitters, Barry ran into Patty yet again and was given her number. At S.T.A.R. Labs, the team learn Jay Garrick had completed the "speed cannon". Before he left, the team managed to convince him to stay until they defeat Zoom.

Finding a new Firestorm partner
Barry and the S.T.A.R. Labs team aided Martin Stein who had yet another reaction. After Cisco used the stabilizer Eobard used on his wheelchair, Barry was told the stabilizer would be transferred over to a power cane. Barry was then told by Caitlin that the latter found potential candidates that could be compatible with Stein. Barry then ran over to the two, quickly snatching blood samples from them for Caitlin to further examine if they are indeed compatible with Stein. Barry was later told by Patty Spivot of a “man-shark” sighting. When Patty asked if they could work on the case together, Barry told her he isn’t into meta-humans, though told her he would run tests on the shark tooth. Barry was then called back to S.T.A.R. Labs, where the debated with Caitlin who was more compatible for Stein. Barry pointed out Jefferson Jackson had the physical attributes and his alleles matched more than Henry Hewitt. Caitlin told Barry that Hewitt is a scientist and someone who was trying to make something for his life. Barry and Stein went to Jackson, telling him they’re an agency collecting data on everyone affected by the particle accelerator. They were told that he doesn’t like talking about the night as his life fell apart because of it. Barry gave him their number and asked him to think on it. When Barry and Stein returned to S.T.A.R. Labs, they found Hewitt. When Stein and Hewitt made an attempt to merge, they were unsuccessful. Jax later accepted his offer and arrived at S.T.A.R. Labs, where Barry revealed they couldn’t fix his knee. The team tell Jackson he could be a hero, though when they told him he’d need to merge with Stein, Jackson left. After Caitlin scolded Jackson for turning down being a hero, Barry told Caitlin that a decision like that can’t be made lightly. Later, Barry told Patty the “shark tooth” had human DNA. Barry was later told by Joe that he was aware of his feelings for Patty. Barry told Joe that she’s great but not Iris. After Henry Hewitt went on a rampage, the team found his police record. After Jax accepted his destiny as Firestorm, Barry, Stein and Jax left to face off Henry Hewitt. They managed to evade his attacks until he became unstable and blew his fuse. Barry and Firestorm then brought Hewitt to the pipeline. The following day, the team said their goodbyes to Stein and Jax as the two left for Pittsburgh. Later that night, Barry ran off and watched Patty from a distance. When he was caught off guard, the man-shark grabbed him and told him Zoom wanted him dead. As Patty walked out, she shot the man-shark several times and the man-shark dropped Barry. The man-shark was suddenly shot by a hooded man. Barry chased after the man, who unveiled his hood and Barry was shocked seeing the face of Harrison Wells.

Meeting Earth Two Wells
Barry brought Harrison Wells of Earth Two to S.T.A.R. Labs. Barry asked if he had any evidence if he was from Earth Two and Wells presented the team with Caitlin's bag which Martin Stein threw into the portal. Cisco asked if he could be trusted and Barry told him that Wells saved his life. Barry proceeded to ask why and Wells told him it was to help him stop Zoom. Joe arrived and fired multiple bullets at Wells, though Barry caught them all. Barry pulled Joe aside, telling him that was Wells from Earth Two and not Eobard Thawne. Joe asked how Barry could even look at him and Barry told Joe that he had to resist the urge to kill him. Later, Barry took Cisco to Jitters, though the latter expected alcohol rather than coffee. The two were interrupted by Patty, who told the two she was right about King Shark. Barry was asked if he could help Patty with a police report but told her he was busy. After Patty left, Cisco asked why Barry hadn't asked her out yet. Barry asked Cisco when was the last time Cisco asked a girl for their number. Cisco made an attempt to ask Kendra Saunders out but was shut down. Cisco then had a vision of Dr. Light robbing Central City Bank and immediately reported to Barry. Barry asked how Cisco knew but Cisco told him to just hurry. When Barry arrived, Dr. Light used a blast of energy to escape. Barry managed to get a few civilians to safety, though Dr. Light escaped. Back at S.T.A.R. Labs, Wells told Barry that she was a small time thief on Earth Two. He suggested they capture her and use her as bait against Zoom. Jay barged in and told him that Wells is insane. He told Barry that though Dr. Light is a thief, she isn't a killer and can be reasoned with. At the CCPD precinct, Barry asked Patty on a date, which she agreed on. Later, the team tracked down Dr. Light. When Barry went to confront her, he told her they could protect her from Zoom. Dr. Light told him that no one could protect her from Zoom, she flashed a light at Barry. Barry told her for just a normal conversation and Dr. Light agreed. Dr. Light unmasked herself and Barry hesitated seeing Linda Park. After saying her name, a confused Dr. Light blinded Barry and fled. Fearing Dr. light may go after her Earth-1 doppelganger, Barry told them they should look after her. After crashing into Caitlin and multiple objects, Jay and Caitlin told Barry to stay behind as they volunteered to look after Linda. Later, Barry went on with his date with Patty, wearing sunglasses with built in cameras for Cisco to guide him. Though he went on with the date smoothly, Patty eventually told Barry she knew he was blind. Barry told Patty that he had his pupils dilated prior and didn't want to cancel. After the date, the two kiss and Barry regained his sight, complimenting Patty's dress. The two were then called to report to Central City Picture News after Eric Larkin was killed by Dr. Light. At S.T.A.R. Labs, Jay apologized to Barry as he never thought Dr. Light would ever kill. After Wells argued with Jay, the two fought, though Barry stopped the two. After Barry told Wells he had retrieved Dr. Light's mask, Wells revealed to the team Cisco is indeed a meta-human, using his Next gen watch to prove so. Barry asked why Cisco never told them and Cisco told the team he was going to eventually. After failed attempts at using his powers to locate Dr. Light, Wells forced it on Cisco. Cisco told Barry Dr. Light was trying to leave town at the South Plaza Train Station. Barry left and confronted Dr. Light once more. After evacuating the train station, he asked how he is supposed to stop Dr. Light. Wells told him to confused Dr. Light by creating speed mirages. Barry told Wells he isn't able to but was told if he was able to travel through time, he should have no problem creating the after images. Barry went on and created speed mirages but Dr. Light sent a blast of light around her, knocking Barry away. Barry told him he couldn't do it but Jay told him he could. Barry went on to create the after images once more and knocked Dr. Light out. After locking Dr. Light up in the pipeline, Barry told them they should listen to Wells and use Linda as bait. A frustrated Jay told them once more they can't trust Wells as he has as many secrets as the one they knew. At Jitters, after Caitlin suggested Cisco should have a nickname, Barry suggested the name "Vibe".

First battle against Zoom
Barry asked Dr. Light for help to stop Zoom, though Light urged him not to, though she eventually agreed. Barry told the team of the trap while Harrison Wells told them he developed a serum that could dampen Zoom's speed. Barry and Joe were then called to the CCPD precinct. At the CCPD, Barry was told by Patty that Joe shut her down on a case and asked if it was because of their kiss, though Barry told her he never told him. After Dr. Light escaped, Barry rushed over to S.T.A.R. Labs but was too late. In fear of Dr. Light going after Earth-1 Linda again, Barry had Iris take Linda into her home. Barry and Joe then had an argument that they shouldn't go after Zoom just yet. Barry reminded Joe that he always said it's good to play offense rather than defense at times but Joe told him that was for football tryouts. At Iris' house, Barry suggested they use Linda to lure Zoom, though realizing what he was saying was wrong, Iris told him it was a good idea. At S.T.A.R. Labs, Barry greeted Linda. The S.T.A.R. Labs team took Linda on a practice run. After a few attempts, Linda eventually succeeded. When he went to hi-five Linda, the latter accidentally fired a blast of light to the former, though he managed to evade it. Later, Joe told Barry that Linda wasn't ready but Barry told him otherwise. Later that night, the Flash went to visit Linda. When Linda said she wasn't ready, the Flash told her she's one of the strongest woman he knew. When she asked what he based that on, he revealed his identity. The following day, Barry was asked by Patty if he could go out for dinner but Barry told her he had something else to take care of that night. At night, Barry and Linda faked a battle where the latter came victorious, though Zoom never showed. Later when Zoom eventually arrived and kidnapped Linda, Barry ran over. Zoom told him that he isn't the only one who fished with bait and proceeded to drop Linda off the roof of S.T.A.R. Labs. Barry ran down and slowed her fall down and caught her. Barry then ran around S.T.A.R. Labs in circles and hurled lightning at Zoom, though the latter caught the lightning and hurled it back at him. Barry then made an attempt a free fall fight for equal velocity though Zoom still came on top. Zoom proceeded to beat Barry and broke his spine. When Wells tried shooting Zoom with the speed dampening serum, Zoom caught it and used it against Barry. Zoom then dragged Barry to Central City Picture News and the CCPD, announcing their hero had been defeated. Barry was dragged back to S.T.A.R. Labs where Zoom shoved his claw like hands into Barry's abdomen, rendering Barry unconscious. When Barry woke up, he was told Linda left for Coast City. Barry then told the team he couldn't feel his legs.

Grodd returns
Barry began walking around with a cane. At one point, he made an attempt to walk without it but to no success. Barry asked how much longer until he should be recovered and Caitlin told him he was almost completely healed. When Wells told the team he was returning to his earth, Caitlin tried to stop him but Barry told her to let him be. When Cisco had a reminder of his date, Barry teased him. Barry then had a call from Patty, who offered to make him chicken soup for his "sickness". Barry went to test his speed on the treadmill. When he tried to push himself, he had flashbacks of being defeated by Zoom and soon collapsed. When Joe asked what was up, Barry told Joe that he couldn't get over being destroyed by Zoom. Barry then told Joe he felt as if the city no longer see's him as the man strong enough to protect them. Later, Joe alerted Barry and Cisco that Grodd had returned. The three chased after Caitlin but were too late. Barry felt guilty he couldn't do anything about it but Joe told him there was nothing he could do to help Caitlin. Later, when Barry ran on the treadmill again, he was greeted by his father, who was called by Iris. Barry caught up with his father and was told that it's good to slow down to get back where he wanted to be. They were then interrupted by Cisco, who had found where Grodd was hiding. When Cisco told Barry he had a plan, Wells revealed himself in Eobard's suit and Barry tackled him. Cisco quickly rushed over and reminded Barry that was a different person and Barry quickly apologized. Barry introduced Wells to his father and told him he would explain "Earth-2" to him later. While Cisco and Wells went looking for Caitlin, Barry was told by Henry he saw what happened against Zoom. He told him that though the city may not believe in him, he would get through it as he had himself when he was framed for Nora's murder. Barry was told that he needed to accept it and believe in himself to get through anything. Barry was also told that him believing his innocence when he was just a kid gave him all the hope he needed. When Wells and Caitlin returned to S.T.A.R. Labs, Wells suggested that they should send Grodd through a breach which would bring him the closest to home he could be. The team had Caitlin lure Grodd and as soon as Grodd caught her attention, Barry got her out of the way. Barry told Grodd that if he wanted Caitlin, he would have to catch him first and Barry ran toward the area of the breach. When Grodd caught up, Barry once again had flashbacks of being defeated by Zoom and was knocked down by Grodd. Barry was pinned down by Grodd with a single foot and was asked where Caitlin was. Caitlin revealed herself and told him they now understand what he wanted. Grodd released his foot off Barry and the team turned the speed canon on, opening the breach and Barry took Caitlin to safety. When Grodd resisted to go through, Barry ran around the city and "super sonic" punched him into the breach. At S.T.A.R. Labs, Barry asked if Cisco could reverse engineer the Eobard's Reverse-Flash ring so he wouldn't need to carry a bag around, in which Wells said he could help. At Joe's house, Barry, Joe, and Iris showed Henry photos of Barry growing up with them. When Joe told Barry Patty wasn't buying his "sick" story, Henry asked if Patty was his girlfriend. Barry told him that he would tell him about her on the way to the bus station. At the CCPD, Barry explained he was keeping secrets was because his father was in town and was afraid that Patty wouldn't have a good image of him, despite his conviction being overturned. Barry was told by Patty that she isn't that kind of person and told her he should of given her more credit but Patty told him he should've given himself more credit. Barry and Patty then share a kiss.

Vandal Savage
Determined to defeat Zoom, Barry continued to hone his speed. However he, quickly realized that he was not getting any faster, which Wells confirmed by pointing out that there were a number of reasons Zoom was more faster and stronger then Barry. Barry however concluded that they would just need to figure it out fast. He then went off to meet Patty. The next day Barry told Joe and Patty that a recent murder at the docks was committed by one man with the only evidence found being traces of a crystal that broke off the killers knives. Later at Jitters Cisco and Kendra were attacked by the same man. Barry quickly came to their aid and saved Cisco when the man threw a knife at him, which Barry stopped. This resulted in a grateful Cisco accidentally revealing Barry's identity to Kendra, much to Barry irritation. Later at S.T.A.R. Labs, Barry and the team determined that the man who attacked them was the same one who killed the others at the docks, with Barry noticing that the daggers were centuries old, and that the man kept referring to Kendra as a "priestess Chay-Ara," and seemed to know her despite Kendra claiming she grew up in Wisconsin and had never left the states. Knowing that the police could not protect Kendra, Barry decided to got to Oliver and his team for help in Star City. Barry proceeded to rescue Oliver, Thea, and Diggle from Damien Darhk and his soldiers from H.I.V.E. At the new Foundry, Kendra was introduced to the rest of the Arrow team. When Thea suggested a description of the mysterious man, Barry used his abilities to draw a sketch of the man. Felicity proceeded to use face recognition software to find a match. When she did she discovered that the only known photo taken of the man was from 1975 meaning that the man should at least be in his 80's. Oliver proceeded to question Kendra more. When his questioning started to get harsh Barry stepped in, only for Oliver to point out that by asking them to help protect Kendra, and by bringing her to Star City, Barry put all of them in possible danger. Felicity proceeded to calm him down and suggested they all go back to their home to relax and catch up.

At Oliver's loft, Barry and Felicity proceeded to catch up and tell each other about what changes had happened recently in their lives. Barry then proceeded to go to Oliver and apologize only for Oliver himself to apologize and tells him that he was glad Barry came to them for help as it showed real maturity, something Oliver claimed he lacked. Soon after Oliver made a toast about how great it was to see everyone again. Later Barry went to Cisco to reassure him that they would keep Kendra safe. Cisco proceeded to tell him that when he kissed Kendra he got a "vibe" of seeing her with wings like a bird with a suit to match. When Barry asked him why he didn't share this information sooner, Cisco told him it was because he thought it was unrelated until now and asked Barry not to tell her about his powers. Not wanting to risk damaging their relationship, Barry agreed to not say anything. Suddenly the man broke through the window of the loft. Barry quickly fetched Oliver's bow and arrows but the attacker begun throwing knives at everyone, forcing Oliver to engage him while Barry protected everyone. Eventually Oliver managed to shoot two arrows into the man's shoulders but Thea impulsively shot the man in the chest and he fell off the balcony. To their surprise, however, the man was nowhere to be found. Back at the Foundry the group tried to find out more about the mysterious man, until Barry suggested they use Cisco's powers. Cisco proceeded to tell Kendra about his abilities and the vision he got of her. Suddenly Malcolm Merlyn and the League of Assassins appeared and revealed the man's name was Vandal Savage: an immortal who has lived over centuries. Malcolm told them they could not protect Kendra, but Barry told Malcolm he was wrong and they could. Later when Hawkman abducted Kendra, Green Arrow and Flash searched for her and found Hawkman, and the two engaged him. He proved capable of fighting them both. After working together they managed to subdue Hawkman and brought him back to the foundry where they questioned him, but he was only interested in Kendra who he also addressed as Chay-Ara. Upon being asked the man identified himself as Carter Hall but revealed that he was really the Egyptian Prince Khufu, and he and Chay-Ara were lovers who have reincarnated over the centuries after their deaths to find each other in each life. Carter also revealed that Savage has, for centuries, hunted down both Kendra and himself and has killed them 206 times, as their life-force is tethered to his, and every time he kills them, he becomes stronger with his immortality and healing reinforced. Barry was confident they could kill Vandal but Malcolm arrived again to inform them Savage has left and is now searching for the Staff of Horus, which will make him near impossible to defeat. Carter suggested that he be allowed to show Kendra how to activate her powers and memories.

Going to the top of a building Carter suggested Kendra jump off to unlock her potential. When she began to hesitate Carter pushed her only for Barry to save her. When he suggested she try again, Barry and Cisco refused. Oliver then pulled Barry aside and asked why he was acting the way he was, with Barry admitting that he felt the rules of how they stop evil keeps changing and how even with powers he still feels powerless. Oliver told Barry however that he had already done enough and after making a joke about Kendra giving him a "lift" back to Central City, they realized that's where the staff was located after remembering Kendra felt drawn to Central City, and came to the conclusion that both her and Carter are attracted to the items that destroy them, or are from their past. Felicity located the staff at a church in Central City. Oliver and Barry raced towards Central City to try and stop Savage, only for him to beat them to it. Oliver and Barry proceeded to try and take the staff away from Savage only for him to overpower them with the staffs power. Savage proceeded to blow the church up using the staff with Barry racing both him and Oliver to safety. Doubting Savage blew himself up the two considered the current situation a tie.

As Malcolm Merlyn arranged a meeting to negotiate with Savage along with Green Arrow and the Flash, while running to the meeting, Barry saw a transparent version of himself come out of a wormhole before dissipating, hinting he would travel back in time soon. Savage demanded Kendra and Carter, or Central and Star City would be annihilated. As Cisco developed gloves to take the Staff of Horus from Savage to kill him, Barry and Oliver go and free Kendra and Carter before Savage kills them. Kendra's powers don't work, leading to her and Carter's death, making Savage near impossible to hurt. Barry uses the Staff against him to little effect along with Oliver. Oliver tells Barry to run, as he's fast enough, before Savage takes the Staff and wipes out Central City with a magical blast, but not before Barry runs through a wormhole to allow him to re-live the last day. With encouragement from Oliver, Barry helps fix what went wrong before, allowing him and Green Arrow to vaporize Savage into ash with the Staff, destroying the weapon itself, and ending Savage for a time.

The Reverse-Flash returns
As Flash was on patrol Cisco informed him of a runaway chemical truck but Flash was unable to stop it as someone rigged it, and was set to collide with a building and destroy an entire city block. Fortunately Flash found a spanner and literally unbolted all the tires, causing the truck to stop. However Flash was soon informed by Cisco that Turtle was dead and sped back to S.T.A.R. Labs, unaware he was being watched. At S.T.A.R. Labs Caitlin examined Turtle and deduced the cause of death was severe brain trauma and Jay noted it occurred the same night he was captured. Jay was quick to blame Harry but he denied any involvement as Barry went back to the precinct to follow up on the runaway truck case. While there however he was very shut off with Patty in regards to her leaving which she couldn’t understand, but Barry simply stated that everyone he loves leaves eventually. Later Flash responded to a break in at Mercury Labs but was horrified to see the trespasser was a still alive Reverse-Flash, though Reverse-Flash was surprised to hear Barry call him by his real name and didn’t seem to be aware of his death. Instead Reverse-Flash simply told Flash that he knew what time period he was from and that soon he would die, and Reverse-Flash knocked him out and abducted Tina McGee. At S.T.A.R. Labs Harry surmised that Eobard is still alive because this is a younger version who hasn’t yet traveled back in time to kill Nora, and travelling through the Speed Force protected him from timeline changes thus protecting him from Eddie’s death thus leaving a timeline remnant of the Eobard who would eventually go back in time and kill Nora. While the team worked on finding Eobard, Barry talked to Caitlin about Tina’s abduction but she revealed that Jay was dying of an illness caused by Zoom taking his speed, but believed the way to cure him was to replace his dying cells with healthy ones but there was only one way to achieve this: His Earth-1 doppelganger.

At the police station Patty asked Barry to look over the evidence from the truck incident which he agreed to but was distant with her, which Patty didn’t understand why he was doing so but he simply said that everyone he loves leaves him eventually. Much later Patty, after looking over old case files and after learning of Barry and Joe’s connection to S.T.A.R. Labs, learned Barry was the Flash and confronted him about it. Barry played dumb but Patty desperately told him he didn’t need to lie to her anymore, understanding why he didn’t tell her, but begs him to be honest now and she’ll stay. However Barry, not wanting another person for Zoom to target or stand in the way of her own future, refused to admit he was the Flash causing Patty to walk away in tears.

Later when Cisco was harnessing his powers to find Zoom he saw a vision of Eobard murdering Tina and taking off back to the future, but Harry was unable to find any trace of a tachyon device being used. However, when Cisco said he saw a clock with the time 9:52pm Harry revealed it was currently 6:00pm, revealing that he can see the future and the team begun searching for Tina. With a mere few minutes left almost 3 hours later Cisco finally found Eobard and Flash spend in after him, stopping him from killing Tina and destroying the tachyon machine. However Reverse-Flash simply said he’d find another way back to his time and challenged him to a race and both Flash and Reverse-Flash sped around the city, but Reverse-Flash was faster. However Flash this time managed to intercept his paths and dragged him into a warehouse where he proceeded to brutally beat Reverse-Flash out of vengeance, ignoring Joe’s protests not to but eventually listened and locked him in the pipeline.

At S.T.A.R. Labs Barry decided to talk to him to get some answers but Harry immediately protested as Eobard would learn more about him and the more he would alter the timeline, but Barry argued that Eobard killed his mother but Harry reminded him that this Eobard hasn’t done that yet and doesn’t know he’s the Flash and he needs to keep it that way. Joe argued however that Harry already stated that Nora was going to die no matter what but Harry elaborated that Nora’s death isn’t set in stone, but altering her death will cause changes which no one can predict. Against Harry’s advice Barry confronted Eobard anyway, remaining in the shadows so Eobard didn’t see his face, and asked Eobard why he despised him so much. Eobard explained that once he was obsessed with the Flash so much he wanted to be the Flash and spent years learning how he came to be, and replicated the reaction that gave Barry his powers. Unfortunately after travelling through time he learned that he was never going to be the Flash but was destined to be his greatest enemy. Following this he grew bitter with resentment towards Flash, believing himself to be superior he dedicated his life towards killing his opposite as “Reverse-Flash”. Barry however was disgusted to learn that Eobard murdered his mother, accidentally informing Eobard that he murders his mother in his future, because he couldn’t be him but Eobard angrily claimed to have become better than him, that he is the one thing Barry will never stop.

However their argument was interrupted when Caitlin informed him that Cisco had begun seizing uncontrollably, and despite getting him stable Cisco physically begun to fade out of existence. As everyone was stunned and clueless Harry realized that Eobard’s capture ruptured the timeline and Cisco is being affected by the effects, and the only way to save him is to send Eobard back to the future. Barry however protested to sending away his archenemy enemy but Joe supported Harry and begged Barry to agree. Barry reluctantly listened but reminded them he destroyed the tachyon device but Harry told them that he and Eobard running around the inner ring of the accelerator in unison, will provide enough the speedsters with enough momentum to break the time barrier and allow Eobard to go home. In the pipeline Eobard was released as Harry talked to Flash, reminding him that this was Eobard’s origins story and there is nothing that can be done to stop it but now he can send him home and move on. Flash however argued that no matter how far he sends him he’ll always be a part of his life. As Flash and Reverse-Flash stood side-by-side at the entrance into the pipeline Reverse-Flash vowed they’d meet again, and Flash agreed but promised that every time he’ll be ready for him and both sped off. After gaining enough momentum the two opened a portal into the future and Flash hurled Reverse-Flash into the portal and returned Reverse-Flash to the future, and Cisco’s life was saved. Shortly afterward Patty called Barry telling him there is a man with a gun on the train she’s taking out of town but as Flash arrived he found no one, except Patty claiming it to be a false alarm. Knowing she knew his secret and was leaving Barry finally stopped speaking with his altered voice and bid Patty farewell as she left for Midway City.

Going to Earth Two
Using Harry’s breach closing device Flash sped through Central City and used them to close the other 50 remaining breaches except the primary one in S.T.A.R. Labs. Afterward Barry, Cisco and Harry prepared for their journey to Earth Two giving their goodbyes to Joe, Iris, Caitlin and Jay and when ready, Jay activated the Speed Cannon and Barry sped himself with Cisco and Harry into it and ventured through the Multiverse. Within he saw numerous other Earths throughout the Multiverse itself and various individuals and objects through existence itself including an Connor Hawke/Green Arrow, parallel Barry Allen/The Flash, Kara Danvers/Supergirl, Grodd, Jonah Hex and a Legion ring. After arriving on Earth Two Barry and Cisco were in awe of how technologically advanced Earth Two is, but they were caught off guard when they ran into the Earth Two version of Henry Hewitt. Unlike Hewitt’s Earth One counterpart this Henry was much more polite, much to Barry and Cisco’s surprise. While in Wells’ office Vibe attempted to use his goggles to find Zoom but the goggles wouldn’t activate and Harry realized they were malfunctioning because the frequency is imbalanced, as Earth Two vibrates at a different frequency. However amidst their shock Barry saw his Earth Two doppelganger on TV being interviewed concerning an attack orchestrated by Zoom, trying assure everyone that “Detective West” has every cop searching for Zoom and promises to stop them. Knowing that he is still a CSI on Earth Two and Joe is still a cop also Earth-1 Barry speeds after Earth-2 Barry and brings him to S.T.A.R. Labs who, understandably, is shocked to see Earth-1 Barry but becomes distracted when he sees Harry and admits how much of a fan he is. This also shocks Earth-1 Barry to see how much more geeky he is on Earth Two but Harry distracted Earth-2 Barry while Earth-1 Barry uses a taser on him to knock him out. Switching his clothes with Earth-2 Barry, Earth-1 Barry goes to the C.C.P.D. of Earth-2 posing as Earth-2 Barry.

At the precinct Barry saw that Captain Singh’s doppelganger was a criminal and that Floyd Lawton/Deadshot’s doppelganger was a police officer. This version was also nicknamed “Deadshot” but not for his perfect aim but rather for his poor aim though he claimed he had gotten better. More surprisingly Barry discovers that Iris’s doppelganger is a police detective and realizes she is Detective West, but Barry is caught off guard when Iris sneaks him into the hallway and starts kissing him revealing she and Barry Two are married. With little choice Barry goes “home” with Iris to the Earth Two version of Joe’s house where Iris tells him his mother left a message, much to Barry’s shock. Barry calls Earth Two Nora and talks to him about the plane tickets to Atlantis “he” gave them and afterward Barry barely held back tears, as he and Iris went to Jitterbugs (the Earth Two CC Jitters). There Barry was shocked to see Earth-2 Joe is a singer but after his performance when Barry talked to him, he coldly reminded him his name was Joseph not “Joe” and addresses him as “Bartholomew”. Barry then quickly realizes that Barry Two’s relationship with Joe is not what it is on Earth One. When Barry talks to Joseph further he coldly blames him for putting Iris’ life on the line to further his own career, stating that Iris had to become a cop so they’d have enough money for his P.H.D., but Iris defended herself saying that writing for C.C.P.N. was boring and she loves being a cop. As they watched Joseph perform they were interrupted by the arrival of two metahuman criminals looking for Barry, but Barry was horrified to see they were the Earth Two versions of Caitlin and Ronnie. When Iris attempted to arrest them Caitlin tried to murder her but Barry tried to reason with Caitlin but she simply stated that she hated the name “Caitlin”, that she is “Killer Frost” and attacks them. When Ronnie fires a fireball at Iris, Joseph pushes her out of the way and takes the hit. While Joseph and Iris are distracted Barry speeds Caitlin and Ronnie outside trying to reason with them but Caitlin attacks with her powers of cryokinesis, then Ronnie flies after Barry as he speeds through the city. However Barry finds a statue of Jay and uses the helmet of it to redirect a fireball onto Caitlin distracting Ronnie long enough to escape.

At S.T.A.R. Labs Harry reveals he’s familiar with the two, “Killer Frost” and “Deathstorm”, but scolds Barry for getting involved into the lives of Iris Two and Joe Two insisting they don’t exist as far as they’re concerned and that Jesse will be dead soon when Killer Frost and Deathstorm inform Zoom of his presence. However Barry angrily insists Jesse has time and Iris and Joseph need him, insisting they are his family no matter the universe. Barry accompanies Iris Two to the hospital as comforts her when Joseph passes away from his injuries and Barry and Cisco, using a weapon build to disable Killer Frost’s power, choose to aid Iris as she and Lawton attempt to bring Caitlin and Ronnie in. Flash hides in secret as Cisco, Iris and Lawton lure Caitlin and Ronnie about but is shocked to see Cisco’s counterpart Cisco Ramon/Reverb who is one of Zoom’s henchmen. As Cisco Two tried to tempt Cisco One into joining him Flash intervened and engaged Killer Frost, Reverb and Deathstorm all at once but was soon overpowered and knocked unconscious. Flash was continually attacked by Reverb and Deathstorm until Zoom appeared and murdered them both for disobeying orders and kidnapped Flash. Awakening in a cell opposite Jesse, Barry tried to assure her he’d get them out but Zoom appeared and scolded him for making promises he can’t keep but promises Barry that his cell is the last place he’ll ever see.

Barry kept looking for a way out of his cell with no luck and tried to keep Jesse hopeful that Harry will find them, after she expresses doubts and believes he only cares for himself, but Zoom returns to remind them Jesse only lives so he can kill her in front of Harry. Barry then notices a man in an iron mask in another cell tapping against the window but whereas Jesse believes he’s insane, Barry suspects he may be trying to tell them something. After agreeing to work together Barry and Jesse discover the “iron mask” is using a 5-5 tap code and become to decode the message. The message turns out to be “J-A-Y” as in Jay Garrick but when Barry tells him he’s alive “iron mask” repeatedly smacks his head against the wall of his cell in frustration for reasons unclear. When iron mask attempts to tell them more Zoom returns and angrily reminds him not to speak again, then phases into Barry’s cell and proceeds to brutally beat him in a fit of rage. Barry then realizes the answer is to phase through the wall but is unable to achieve the frequency.

Later Barry and Jesse are found by Harry, Cisco, Iris, Caitlin and Barry Two but whereas Caitlin is able to free Jesse, she is unable to freeze open Barry’s cell which Harry confirms is because it’s made of a form of carbine. Barry tells everyone to leave but Barry Two refuses and confronts him about all they’ve been through to get to him, all the things he’s done, impossible things, because he had to prove to himself and Iris that he could, reminding Barry One that he is The Flash. Motivated by Barry Two’s words Barry One finally manages to phase through his cell only for Zoom to appear after Killer Frost tells them of their plan. Barry One pleads with Zoom to let everyone else go as Zoom only needs himself and Harry and while Zoom acknowledges this, he makes no exceptions for everyone else and grabs Jesse. Before he can kill her Caitlin blasts him with her ice beams and everyone escapes except for Barry who refuses to leave without iron mask, but Harry insists there isn’t enough time. Before leaving Barry promises to get iron mask which he accepts and Barry flees. At S.T.A.R. Labs Barry One urges Barry Two and Iris Two to find shelter and reminds Barry two that though he isn’t a superhero like he is, he’s still a hero. When Zoom approaches Flash manages to get Cisco and Jesse to Earth One but when he returns to Earth Two Zoom is waiting with Harry hostage who insists he close the breach. However Harry has a dart and Flash distracts Zoom long enough for Harry to stab Zoom and Flash speeds Harry back to Earth One and Jay closes the last breach. However, as the team is happy to see the last breach closing Zoom reappears and stabs Jay right through the chest, and drags him back to Earth Two leaving the team to believe him dead. After the horrific tragedy, Caitlin starts to deny Jay's death, not wanting another lover to pass away. Cisco then brings her upstairs. Barry then demands Wells to open up the breach again, only for Harry to tell him that he can't, as the device they used was strong enough to close and prevent any breach from opening, ever, telling them that they can't do anything now, as they are now safe. When Barry went upstairs, he talked to Cisco about how Caitlin was doing, and what this incident is going to do to her. Wells chimes in, telling them that it will be all right and not to tell anyone about their experience from Earth Two. They reluctantly agree.

Return of King Shark
After the incident, Barry went to his life as usual. Although secretly he wanted to tell about his adventures, feeling frustrated about his circumstances, wanting a distraction for him to ignore all of it. He though started to act strange around his foster family, not wanting to play games with them. One day, a week later from their trip to Earth-2, two guests arrived, known to Team Flash, John Diggle and his wife. They notified the team of King Shark, believed to be dead. John notified them that he was in A.R.G.U.S. prison until recently where he escaped, intent on going after Barry. They also revealed that A.R.G.U.S. was keeping track of meta-humans, weaponizing them. John told Barry that they were going to take care of him but Barry obliged. Though Diggle insisted that A.R.G.U.S. recapture King Shark, Barry refused, as he was the last of Zoom's henchmen and was going to take care of him himself. They then worked together to try to stop King Shark. During the search, Joe called Barry, asking him to come over to help Wally with his engineering project. Though not wanting to go, due to the situation at hand, Barry accepts, much to Joe's surprise and delight. Barry then searches for King Shark, with the help of A.R.G.U.S, but in the end, they couldn't find the shark meta. Barry ran to John, telling him the results and asked him about Felicity, knowing that she was in the hospital after Dahrk's attack on Christmas, Diggle says she was okay, as she is a tough woman. John then remarked that he was like Oliver, "holding the world on his shoulders." However, it was during this conversation when King Shark attacked A.R.G.U.S. then ran off.

Revelations of Zoom
Following the confrontation with new speedster Trajectory, her reaction to Velocity 9 helped Barry and his allies realize that Jay Garrick was actually Zoom. Seeking a means of increasing his speed, Barry traveled back in time to the previous year to talk with Eobard Thawne/Harrison Wells, reasoning that his old mentor/enemy would know the secret of increasing speed if anyone did. Although his plan to simply pose as his past self failed due to the intervention of a Time Wraith, Barry was able to trick Eobard into providing him with the information he needed by claiming that Eobard would return home in his time and he had left information about Eobard's real identity where his past self would find it unless he was allowed to return to his own time. With Eobard's information, he and his STAR Labs friends helped him build a new tachyon device. While testing this out, he accidentally opened a wormhole to another Earth and met Kara Danvers/Supergirl. She helped him get home after he helped her fight two of her enemies Livewire and Silver Banshee, but when he returned only a second had passed and nobody knew it. After the team discovered new revelations about Zoom's real history as Hunter Zolomon, Barry attempted to lure Zoom into a trap, but this backfired when Zoom escaped and captured Wally, forcing Barry to surrender his speed.

Powerless
Now deprived of his powers but with Central City still endangered by metahumans, Barry attempted to continue to act as a hero when Doctor Wells was abducted by Griffin Grey, but his subsequent beating made it clear that this plan was never going to work. Despite the team attempting to compromise by using a holographic recreation of the Flash to fight crime, after Zoom returned to attack Central City, Barry decided to go along with a risky plan of recreating the particle accelerator explosion on a smaller scale in the hope that it would restore his speed. Although this effort seemingly vaporized Barry, he was actually sent into the Speed Force itself, where his encounters with aspects of the Speed Force masquerading as Joe, his mother and himself helped him accept his mother's death and his identity as the Flash before he returned home, his powers restored and even increased.

In April 2016, Barry traveled to Star City to attend the funeral of Laurel Lance, but was held up due to the encounter with Zoom, causing him to miss the funeral but arrived afterward to talk to Oliver at the grave-site. Upon asking Oliver if there was anything he could do for him, Oliver told him that he wished to be left alone, which Barry acknowledged and then sped off.

Return
With his powers back, Barry faces off against platoons of Earth-2 meta-humans that Zoom unleashed upon Central City, with one of them being the doppelganger of a recently deceased friend., Laurel Lance. Barry takes it upon himself to fight her after she attacks Mercury Labs. Team Flash had manages to build a machine that will render all Earth-2 beings unconscious. The device works and Earth-2 Laurel is locked up. However Hunter kidnaps Henry and tells Barry that his inability to be selfish made him weak, and kills Henry in front of him. Henry's funeral is held shortly after that, with Barry wanting to take revenge on Zoom. However doing so made him emotionally uncontrollable, so he is locked up for some time. Wally later releases him, and Barry finds out that the team tried to take down Zoom on their own, with Joe taken. They realize they have no choice, so Barry (with the help of Cisco's vibes) arranges the race with Zoom. Zoom reveals he plans on destroying the Multiverse, leaving only Earth-1 behind, with a pulsar he built. Barry races against him, summoning Time Remnants to help him. Zoom is finally defeated and is taken away by Time Wraiths. Sometime after that, Team Flash returned to Earth-2 and rescued the man in the iron mask, and his identity as it turns out was the actual Jay Garrick and Henry's Earth-3 doppelganger. They open up the Speed Cannon and send Harrison, Jesse, and Jay back to their worlds. That night, Barry and Iris declare their love for each other and kissed. Barry, to distraught after his father’s death sped back to the past to the night his mother was killed to save her, shortly after his older self sped off with his 11 year old self he ran into the house and grabbed Eobard seconds before he stabbed Nora after which he knocked him out, thus drastically changing the timeline and causing his younger self to fade from existence to which he assured Nora that she was safe.

Flashpoint timeline
After defeating Eobard, Barry took him to back to 2016 and used a abandoned building to lock up his nemesis in a specially designed cell to keep him from harming people. Barry sees that that time has changed, most noticeably being that his parents are alive and well. While his past self has lived happily with them all these years, this also left Iris never having grown close to or even really knowing Barry and Joe as an alcoholic with a strained relationship with Iris, and a new speedster vigilante as the Flash. After three months of bliss with his new life, and periodically bringing food to Eobard in secret, Barry finally works up the nerve to ask Iris on a date, which she agrees to. Soon after, the new Flash begins struggling against an evil speedster called the Rival. After narrowly saving the other Flash, Barry learns that his replacement is in fact Wally. Barry also starts to lose his memories of the first timeline, which Eobard theorizes is from Barry reckless use of his powers in a timeline that he never actually obtained them.

Eventually, Barry reveals his true identity to Wally and Iris, the latter who is aiding Wally as the Flash. They got for help from Cisco, who is now an obnoxious and self-absorbed billionaire businessman. After convincing him to help them track down the Rival, Barry and Wally team up to battle the Rival. Though Barry defeats the Rival, Wally is mortally wounded. Realizing that the new timeline is worsening his friends, Barry releases Eobard to lets him kill his mother. When gets back to the reset timeline Barry discovers that the timeline wasn't reset right due to him learning that Iris and Joe haven't spoken to each other in months.

Post-Flashpoint timeline
Barry eventually went to Felicity to explain some of the changes to the timeline: Joe and Iris haven't spoken due to Joe not telling her about her mother, Cisco is depressed due to Dante dying in a drunk driver accident, a new cynical co-worker, Julian, and to their horror, Sara being replaced with John Diggle Jr. One finished, Felicity advises that Barry finds a way to make things right. While attempting to clear the air with Team Flash, he also learns that the distance between him and Cisco was also due to him not turning back time to save Dante. Suddenly, an alert went off, and Barry discovers that Edward Clariss was able to become The Rival again, and speaks with him for a bit before facing him in a close fight which ended when Barry managed to ram into him, casing him to flying across city blocks into the bay and out of sight. Iris later confronts Barry over what she learn from watching Barry and Clariss talk, and demands the truth or their relationship won't have a chance. Barry apologizes, saying he's been trying to fix things, but now believes that there is only one way to do so, before racing off to try and time travel again before being stopped by Jay Garrick, who then speaks to him about how he can't just keep trying to use time travel to fix every mistake.

He then explains to the team how he created it then attempted to put things back the way they were, but with a few variations so far. While he finally tracked down The Rival, he was attacked and injured by a hooded figure calling himself "Alchemy", who explain some of his intentions before being attach by Clariss again and overwhelm The Flash, being to injured to fight back properly. He was about to be impaled when Cisco came to the rescue, and helped defeat Rival, somewhat forgiving him in the process. He later learns that Iris and Joe have reconciled and he and Iris start dating.

Return of the Wells' family
Later during a date with Iris, a breach was open in S.T.A.R. Labs, Wells came back with an unexpected surprise: a super-fast Jesse. Barry and the group goes to the speed lab to test Jesse. when Barry learns that Wally stepped into the street to try to get his speed. He screams at him for his careless idea. Later he and Wells talk about the mistakes that they made. Soon, he and Jessie team up to defeat Magenta. Later, he and Joe watch a security video of Clariss get killed by an invisible meta-human in Iron Heights.

Various events
In the future Barry has a museum built in his honor. In another unspecified time, presumably erased, Flash teams up with Atom, Captain Cold and White Canary against the The Leviathan. At another unspecified point in time, Barry is arrested and sent to Iron Heights for an unknown crime, and appears to be talking either to Jay Garrick or his father while in prison. For reasons unknown he also created Gideon, an artificial intelligence, and became the founding member of an organization. Before 2024 Barry and Iris' feelings grow deeper and they marry resulting in Iris changing her name to Iris West-Allen. Also, according to Eobard, his speed at this point is limitless and he also says that he's experienced and a veteran hero. However, since Eobard's memories are that of an older timeline, it's possible that in the current timeline Barry's fate is different.

Crisis in 2024
Around midnight at an unknown point in the year 2024, Flash battled Reverse-Flash with Green Arrow, Atom and Hawkgirl in the streets of Central City causing the most destruction the city had ever seen. The fight also somehow caused the sky to turn a deep crimson color. Their fight caused several trucks to start leaking their contents onto the streets, and caused power outages spread over 20 blocks throughout the city. Reverse-Flash and Flash then started battling over two overturned tanker trucks, and the lightning emitted from them caused the oil from one of them to ignite. While sounded by smoke both speedsters had a very heated conversation on an unknown matter, then the two sped off leaving Green Arrow, Atom and Hawkgirl behind. The two then continued their fight up and down an unknown avenue then vanished without a trace.

Travelling back to 2000 moments after the Reverse-Flash had arrived, and followed his arch-foe to the Allen house and the two fought around Nora. During the fight, Flash saw his 2015 self during his first trip into the past and for reasons unclear, though presumably because of the effects of Flashpoint, signaled his younger self not to interfere. Flash then continued to fight his enemy before taking his 11 year old self out of the house and transported him 20 blocks away, before vanishing into the night. It is possible that these events were exclusive to the original timeline, before Eobard Thawne's alterations, and won't happen in the new one, or happen in a different way.

Contacting Rip Hunter in 2056
At some point in 2056 a 67 year old Barry contacted former Time Master Rip Hunter, leader of the Legends and told him that a war is coming, but made him promise not to tell the rest of his team.

As a civilian
Barry is described as someone who complements Felicity Smoak's intellect level, both when it comes to forensics, as she claims it's not her strong suit, and science in general. He is also someone who is regularly late as he missed a train, boarded a late train, and misses a cab all to get to Queen Consolidated's warehouse, and missed the last train back to Central City. He is also considered a comic geek.

Much like Oliver, he has a strong sense of justice, due to the fact he knows his father is innocent of a crime he was convicted of. He joins the forensics department to both learn how to investigate crimes, and study cases with unexplained elements, to prove his personal account of his mother's murder true, and ultimately, free his father. Barry is very intelligent, like Felicity, he is socially awkward, as he sometimes gets nervous and babbles.

Barry has good morals, as he does not like to lie about who he really is, like when he first met, Oliver, Felicity and Quentin, and told them he was a forensic scientist, this was only because he knew they wouldn't take him very seriously if they knew he was only an assistant forensic scientist. When Oliver confronted him, after he found out who Barry really is, he did not try to deny it, but also explained the reason why he did it.

Barry has a lot of respect for the vigilante known as the Arrow. When he found out that Oliver/the Arrow are the same person he is amazed, he also saved his life after he was injured by Cyrus Gold and consequently poisoned, despite the fact that he barely knew Oliver at the time, he also keeps his secret. Despite his respect for Oliver, Barry is not above standing up to him, like when he pointed out that Oliver was being a jerk to Felicity, though he said this in a respectable way.

Additionally, as said several times by Joe and seen many times throughout the series, once Barry makes up his mind about something, makes a decision, or sets his mind to something, it is impossible for anyone to talk him out of it, including Joe, Iris, and even Henry Allen.

As the Flash
When he first discovered his new-found powers, he wanted to help people. When he first tried to stop Clyde Mardon, someone unintentionally got killed because of his actions, and he lost his confidence. However, after getting advice from Oliver, he regained his confidence. As the series progresses, Barry becomes more and more confident.

Oliver mentions Barry is very stubborn and isn't likely to learn from his flaws until experiencing them firsthand, as shown during his training with Oliver. This prompted Oliver to show Barry a potential consequence of not surveying his surroundings before charging at an enemy by shooting him with two remote controlled crossbows.

Despite his dislike of crime and meta-humans who use their new-found powers for evil intentions, killing and torturing his enemies is a line that Barry would never cross, as he criticized Oliver for torturing Klaus Markos to gain the location of Digger Harkness. He even stated that he does not use his bad experiences as an excuse to torture people in general who makes him angry.

Barry is shown to be selfless and honorable, like when he found out that Eddie was going to ask Iris to marry him, Barry did not try to stop this engagement, despite recently discovering future events; that Iris will become his wife, instead of Eddie's. Also, he pushed Patty away partly because he didn't want her to sacrifice her dream of being in CSI for him.

However, after Eddie sacrificed himself so that his descendant Eobard would have never been born and Ronnie had done the same so Central City could be saved, Barry's personality became slightly darker. He became more reclusive, distant and cold to his friends, he broke up Team Flash and went "the Lone Wolf". He also began to doubt himself as a superhero as he couldn't have saved Eddie and Ronnie and even considered not going to Central City's Flash Day, but after being motivated by Iris, he decided to go and reunite Team Flash. Even with this, he still remains somewhat guarded, especially after being brutally beaten by Zoom, he became even more so, even in his love life, as shown with Patty to point to let her go for her own safety and happiness.

He became less trustful of people, when Jay Garrick claimed that Earth One was in danger by another speedster called Zoom and that he was the Flash of Earth Two Barry did not believe it, even though most of his friends did but this was mostly due to the fact that Jay reminded him of Eobard Thawne, he eventually overcame his suspicions and allowed Jay to train him to defeat Sand Demon.

Barry began to show less concern for his enemies' well-being as he gave Atom Smasher an overload of nuclear energy which killed him and solidified Sand Demon which again kills him however Barry probably didn't expect it would kill them. His killing of Atom Smasher was due to his strong belief he would harm others. However, he did apologize to Atom Smasher before he died as he felt guilt, care and remorse, while he felt none for Sand Demon's death. This is likely because the latter villain was a homicidal maniac who did nothing to try to avoid the death of innocents. Finally, he was willing to kill a reanimated and mindless Tony Woodward, but felt it as a mercy killing and said that despite them being enemies, he still wanted Tony to be at rest.

Barry is a forgiving person, after Eobard was erased from existence, it took him months before he finally forgave the latter for murdering his mother, and framing his father for his crime.

Despite his honorable ways and proclivity for pacifism in the face of deadly and often ruthless and sociopathic enemies, Barry does harbor some very disturbing and homicidal feelings towards some of his enemies in particular. These two being Zoom and the Reverse-Flash, due to their parts in the deaths of his father and mother respectively. After the capture of Eobard Thawne in the particle accelerator on the first occasion, Barry expressed an unhinged and blood-thirsty desire to kill him, even spitting with rage when he voiced this overwhelming need of his. This is in almost direct opposition to his normally restrained and merciful attitude towards his enemies. His desire to kill Hunter Zolomon may even be greater, due to how thoroughly Hunter had betrayed Barry and his friends, and how Hunter tortured Barry by kidnapping his father and then stabbing him through the chest with a vibrating hand, all the while this death took place in the same room where, approximately 17 years prior, Barry's mother was murdered by Eobard. This replication of his mother's murder with his father profoundly affected Barry, and has awakened a need for cold-blooded vengeance in him that he has never felt before, having had the pain of losing both parents in the same way, each to a deranged speedster, compound one another, tearing him apart emotionally.

Because of all the tragedy Barry had suffered and being unable to cope with it, he made a trip back in time, saving his mother, reforming the current timeline. Despite him seemingly recovering, Barry does not hesitate to kill the Rival after he impaled Wally West in the back, the only thing stopping him from doing so is his memories fading away. Once he realizes how big a mistake he made once seeing Wally injured, he attempts to correct the time, yet is only somewhat successful. When Jay Garrick intervenes his attempts to correct the damage timeline, he taught Barry that time travel must not be abused, and he must learn to live with his mistakes, instead always trying to undo them.

Barry's heroic and peaceful nature hid a more complex and powerful set of emotions that he does not fully express but has always harbored on a subconscious level. While as both civilian and the Flash or when pushed over the edge by enemies, Barry has been known to act on nearly 14 years of repressed anger and emotional stress. These emotions are obvious after being exposed to Roy Bivolo, voicing unfounded contempt for others unusual in Barry's usually calm nature and respectful attitude such as snapping at Joe for imprisoning and criminalising his father, speaking down at David Singh for his constant barking/disrespect and condescendingly voicing jealousy for the Arrow. Barry admits that after being cured that although it was Bivolo's doing, he did mean some of the things he said during his fight with Oliver.

Powers

 * Speed Force connection/Meta-human physiology: Barry's powers come from his connection to the Speed Force, which was established after being struck by dark matter lightning and exposure to various chemicals. This altered his DNA and supercharged his cells, augmenting his physiology into a lean-muscular frame that is well-beyond peak human condition. This lets him properly handle the rigors of his powers, including resistance to high levels of friction, inertia, air pressure, reduced oxygen, and kinetic impact. By directly access the Speed Force, he can use more advanced abilities. When trying to regain his powers, Barry entered the Speed Force itself. The experience made him consciously aware of the Speed Force and strengthened his connection to it, realizing much of his true potential.
 * Accelerated healing factor: Barry has dramatically heightened healing capacities. His molecules move at accelerated rates, causing his metabolism to mend and even restore any damages much quicker and efficiently than regular humans. He needs only hours if not minutes to recover with no treatment or lingering signs of the injury ever happening. Even normally permanent damage, like becoming a paraplegic, will completely repair itself within days. He recovers from any illness or contaminant instantly if not completely immune to it. Even when injected with 2,000 milligrams of horse tranquilizer, Barry was only momentarily slowed down until his body burned through it. His accelerated healing also enhances his vitality, drastically reducing his aging process while extending his health and longevity.
 * Bodily vibration: Barry can vibrate different body parts for various effects. Vibrating his entire body can mask his form from being clearly perceived or distort his vocal cords to disguise his voice. Similar, he can vibrate his cells to forcibly expel any toxins that do affect him. He can also generate great amounts of heat to recover and even be kept thermally insolated from extreme cold. By vibrating at varying frequencies and with different levels of force, he can create small tremors to induce extreme amounts of jolt on any target he touches, even disrupt the inter-molecular bonds and cause it to shatter. Offensively, he can vibrate his limbs, creating a buzz-saw effect to seamlessly grind through a target as he did to free Joe from his metal confines. If he desires, he can use this technique to harm or kill a person, as he was tempted to do to Zoom.
 * Intangibility: By vibrating his molecules at the same frequency as air, Barry can physically phase through solid objects. He can even phase people through things as he did with Joe West and Eddie Thawne, while they were persecuting criminals in a car chase. His efficiency with this skill has continued to grow as he became able to use it to pass through living individuals as he did to escape Atom Smasher's grasp. He could even phase through the highly complex material of carbine while in another universe that's vibrational frequencies differed from his own.
 * Electrokinesis: When moving at high enough speeds, Barry can produces a yellow electricity from his body and can use it in many ways. He can generate enough friction on a specific part of his body, such as his hands, to produce a strong static shock. After training by Hunter Zolomon, Barry learned to harness this build-up of electricity, to which he can repeatedly hurl lightning bolts and electrify water.
 * Speed Force sharing: After regaining his connection to the Speed Force and obtaining a greater understanding of its nature, Barry learned to use the Speed Force in more passive means. He can allow another target to temporarily experience the energy of the Speed Force. Doing this, he can make a person to heal as fast as himself, as shown when he made Jessie recover immediately from a coma by touching her with the Speed Force electricity from his hand.
 * Enhanced mental process: Barry's speed enhances and extends to his mental capacities, making his system and thought processing able to take in information just as fast and efficiently. Even while using his raw speed, he can clearly think, react to events, and perform actions long before normal humans can perceive them. This lets him learn in a small fraction of the normal time, able to familiarize himself with Earth-Two science within minutes.
 * Enhanced perceptions: Barry's speed extends to and enhances his senses. This allows Barry to perceive the world as if it is nearly frozen, as well as see and hear normally, even while moving at speeds faster than sound, where this would normally be impossible.
 * Enhanced strength: Barry's physical strength has been heightened to peak human capacities, greatly belying his slim built. He is able to carry multiple people at once while speeding away with them. He can also smash through machinery with his bare hands.
 * Superhuman agility: Barry has demonstrated flawless coordination, equilibrium and dexterity. He can change direction with immediate sharp turns without sliding or losing balance. He can jump and run along falling debris and launch himself tremendous distances with little build-up.
 * Superhuman durability: Barry possesses inhuman resilience to injury, taking attacks and exertion much easier than normal humans. While not invulnerable nor immune to pain, he withstood Weather Wizard's lightning and Grodd's powerful strikes, only being momentarily stunned. After regaining his powers, his resilience increased as he could quickly rebound from the zombie Girder's attacks, who could seriously injure him during their last encounter. Barry could also withstand sonic blasts from Black Siren that are powerful enough to kill normal humans.
 * Superhuman reflexes: Barry's reaction time is augmented to superhuman levels, allowing him to react to danger and events far faster than normal humans. When shot in the neck on his blindside, Barry caught the bullet and minimize the damage before it could fully penetrate his skin.
 * Superhuman speed: Barry can move at vast speeds, able to run across vertical structures and over large masses of water. Using this for his various daily activities, he can near-instantly complete his different tasks. He is faster than Supergirl, ranking him among the fastest in the multiverse. While reaching Mach 3.3 on his own and later Mach 13.2 from tachyons, since strengthening his connection to the Speed Force, Barry has naturally gotten considerably faster than ever, able to outpace Hunter Zolomon, who became much faster after stealing Barry's original speed energy. Even when weakened in the Flashpoint timeline, he outmatched Edward Clariss/The Rival. Barry's speed is potentially limitless, according to Eobard Thawne, who in one future his speed matches the evil speedster's.
 * Aerokinesis: Barry can use his speed to generate air flow as vacuums on various levels. He can create vortexes to suffocate people or extinguish fires by forming it around them. He can create large and strong tornados, able to repel massive targets. Alternatively, he can use this skill to propel himself through the air as a pseudo-form of flying. He can completely removing the physical force from massive tidal waves, stabilize a giant singularity, or dispel F3 tornadoes, by running around them.
 * Speed mirages: Barry can make it appear like he's in many places at once, when in reality, he is simply bouncing back and forth too fast for the human mind to perceive the difference. He can create dozens of after-images, allowing him to disorientate his enemies and then catch them off guard.
 * Superhuman momentum: Barry can generate great amounts of physical force through kinetic energy, simulating superhuman strength, even in a stationary position. He can propel himself through the air and create substantial frictional force with any object he comes into contact with. His speed lets him channel the force into powerful strikes, propelling targets several feet. Barry can hurl a bullet with enough force to penetrate a powerful barrier and still pierce clean through a person.
 * Time travel: Barry's can breach the temporal barriers, letting him enter different points in time. While originally only accessed by accident when under extreme stress, Barry learned to use it at will arrive at a destination with pinpoint accuracy. He is able to use this power in one of two ways; either travelling to timelines independent from himself and unaffected by his actions or perform a time do-over, wherein he essentially "merges" with his temporal counterpart to be fully immerse in the timeline. Regardless of the changes, Barry's powers can leave him unchanged and retain all memories of the previous timeline in addition to the new timeline and differentiate between the two.
 * Time remnant construct: Barry is able to "create" a time remnant by time traveling back to moments before his current self time travels, hailing from a future that no longer exists. This effectively allows Barry to be two places at once, enabling him to interact with world for two separate actions simultaneously. However, Barry admits he cannot use this ability often.
 * Interdimensional travel: Another more advanced ability, Barry is capable of moving fast enough to break open portals between dimensions, allowing him to travel to different universes. If desired, Barry can also bring others with him as he did with Harry and Cisco to Earth-Two. While originally he could not consciously control this, as his first solo use was done by accident and required assistance to return to his own world, after greatly increasing his Speed Force connection, he can break open portals to other worlds of his own accord.
 * Superhuman stamina: Barry can handle the stresses of extreme racing without noticeable distress, letting him function much longer than normal humans unhindered. His enhanced stamina is due to his augmented physiology, which builds up little to no lactic acid or fatigue toxins. Even after running from coast to coast of the country to pick up a pizza, Barry remained unfazed from the prolonged running.

Abilities

 * Artistic: Barry is shown to be an effective sketch artist as he redrew an image of Vandal Savage's face, which freaked out John Diggle.
 * Expert computer skills: Barry has became adept with computers, as he was the only one who could write an algorithm to find Livewire that monitored the electrical manipulations to the network that her powers cause.
 * Expert engineer: Barry has very advanced skill in technology. He was skilled enough to recreate from memory a variation of the earpieces used against Hartley Rathaway to help himself and Supergirl confront the sonic-powered Silver Banshee. He was also able to build a prison from which Reverse-Flash couldn't escape. In one possible future he creates Gideon, a very sophisticated artificial intelligence unit that's system was so complicated that even Cisco had no idea of how it works.
 * Expert scientist/Forensic expert: Barry is a highly skilled forensics examiner. From a single glance of the crime scene, he can quickly determine much of the events that transpired. Barry has repeatedly been able to quickly analyze any given data and quickly form accurate theories on the given situation. With the Arrow, Barry correctly determined the Arrow's training background from his green attire, and that the Arrow has at least one accomplice.
 * Genius-level intellect/Skilled tactician/Leader: A keen-minded individual, from a young age, Barry quickly showed a natural understanding and quick capacity to learn, making it hard for his foster-father Joe to help him with homework by the time he was twelve. Barry is also very well-read, greatly impressing the award-winning professor Martin Stein. Barry is a capable tactician and leader. After Eobard Thawne was exposed as Reverse-Flash, Barry was able to keep his team together and lead it well. Barry's intelligence made Eobard trust him enough to make Barry the new CEO/Owner of S.T.A.R. Labs. The same can be said for his growing tactics in battle. He is also proven to be a quick study and sharp memory as after reading through the various Earth-Two advances in physics, he instantly began making effective use of it.
 * Marksman/Firearms: Being in the Central City Police Department, it is possible that Barry was trained to standard handguns. In, Barry is shown using a tranquilizer gun down in the sewers.
 * Physics/Chemistry expert: Barry's knowledge and skill in chemistry is very advanced, shown when he was terrified at how certain dangerous chemicals were stored at a lab at Queen Consolidated. He was also able to cure Oliver Queen using only a small amount of rat poison and consequently dosed with a blood coagulant. He could also use unknown types of chemicals to make a compressible micro-fabric green domino mask for Oliver so he could conceal his identity more effectively than with grease paint without affecting Oliver's sight and, by extension, his aim. Barry's knowledge on physics possibly ranks among the best on Earth One and Two as he was able to apply to apply a newfound science and figure out how to close the various breaches between worlds.
 * Singing: While not a fan of performing and being quite modest about this skill, Barry is shown to be a high quality singer. When being dragged into singing at a dive bar, it ultimately attracted the attention of Linda Park.
 * Skilled hand-to-hand combatant: Despite not having much training or experience in unarmed combat, Barry's superhuman speed and reflexes combined with his intelligence makes him a formidable opponent. In, he was able to fight Oliver as an equal, despite the latter being more experienced in unarmed combat than Barry. Through his various battles however, Barry continued to improve his prowess, becoming a highly proficient self-taught brawler as he decisively defeated three fellow speedsters, Hunter Zolomon and Eobard Thawne, along with the Flashpoint timeline speedster while being affected by memory altercations of Flashpoint, Edward Clariss.
 * Speed Force expert: As of, after receiving the speed equation from Eobard, Barry now has great intelligence about the Speed Force and its usage. He can now also use it fluently in combat, something he was previously unable to do, due to his lack of experience at the time. After regaining his connection to the Speed Force in , Barry gained a greater understanding of its nature. Also with his newfound awareness and understanding of it, Barry can instantly use more advanced abilities and likewise improved his natural performance for much longer durations unhindered. Furthermore, he knows how to nullify another speedster's power as he did to Eobard for three months, which he may have learned from Zoom's prison.

Weaknesses

 * Carbine: Barry's intangibility has difficulty passing through this compound, requiring him to build up even more momentum to get past.
 * Cold temperatures: Because speed is produced by a build-up of heat in the target's atoms, Barry is vulnerable to extreme cold temperatures. Under these conditions, Barry's speed will be greatly reduced. Also, direct exposure to such cold will temporarily stunt his healing capacities.
 * Electricity absorption: Barry's unique biology causes his body to produce massive amounts of electricity, which charges his molecules to allow for his accelerated movements. Should Barry be drained of this electrical energy, he will lose his powers. However, as this power is genetically coded to his DNA, he can potentially regain his speed by using more electricity to jump-start it.
 * Hyper-metabolism: While moving at accelerated speeds, Barry burns calories much faster than a normal person. While breaking down food far more efficiently, this also requires him to consume large amounts of nutrients. Continued usage of his speed while deprived renders him disoriented and weak before ultimately passing from low blood glucose. Also, because of his accelerated healing, he is unaffected by painkillers or sedatives as he burns through them too quickly to have any effect. He also cannot experience joys like getting drunk as even consuming a 500 proof alcohol only intoxicated for a few seconds. After naturally increasing his connection to the Speed Force, his performance noticeably increased, requiring less nourishment in-between his vigilante exploits.
 * Kinetic energy absorption: Because Barry's abilities are derived from movement, the removal of the kinetic energy he builds up will leave him in a state of temporary paralysis. However, if he can build back up enough kinetic energy within himself, the effect can be instantly negated.
 * Time alterations: While Barry's speed can break through the temporal barrier, it is not without drawbacks. In addition to potentially causing unforeseeable, damaging changes to the timeline, such reckless actions can alert the Time Wraiths. These temporal guardians become instinctively drawn to the careless speedster, driven to capture him and draw the person into the Speed Force. Also, as shown in, using his powers in a timeline he didn't actually acquire them will gradually deplete them and make him forget the original timeline.

Equipment

 * Earpieces: On his suit's cowl, Cisco installed two lightning-bolt shaped earpieces on Barry's suit to maintain a communication link, which he can manually turn off. The devices also include headset cameras to maintain video coverage.
 * Hidden camera: Before "The Brave and the Bold", Cisco installed a mini-camera in the emblem on Barry's suit to give his team live video coverage in order to see where he is and better assist him.
 * The Flash suit: Barry wears a protective suit as the Flash, to hide his identity when fighting crime designed by Cisco Ramon. The suit is made out of a reinforced tri-polymer and is heat and abrasive resistant, organically designed to replace firefighter turnouts. It was re-purposed to help protect Barry from the vigor's of his speed and survive certain environments. It also includes built-in sensors to track Barry's vitals, location, power output, speed level, and to stay in contact with S.T.A.R. Labs.

Former equipment

 * Tachyon unit: After travelling back in time in "Flash Back", Barry convinced Eobard Thawne to give him the knowledge of how to produce a Tachyon unit, amplifying his ability to absorb the Speed Force into his system. When using his speed while wearing the device, it also gives Barry the extra benefit of lowering his calorie burning rate to a normal level, allowing him to keep moving longer without drawback. However when Earth Two Harrison Wells later "miniaturized" the device to fit securely beneath the Flash emblem on the suit's chest by using the Speed Force transmitter, this device became useless.
 * Speed Force transmitter: While testing the tachyon unit, Barry felt some limitations to the machine despite its benefits. Because of this, Harry redesigned the Speed Force transmitter to transfer the tachyons directly into Barry. With its smaller design, it can be concealed under the Flash suit's chest emblem. It also retains all the tachyon unit's benefits with the addition of letting Barry act with less movement restriction and without being weighted-down. It was presumably destroyed when Harrison attempted to recreate Barry's powers. Due to his Speed Force connection being enhanced, Barry was able to beat Zoom without it.
 * Voice filter: After Barry temporarily lost his powers he became unable to naturally disguise his voice. To compensate while talking to Wally West, he was given a voice filter similar to Oliver Queen's.

Trivia

 * In the original timeline, Barry did not become the Flash until the year 2020.
 * According to Barry's Facebook page, his favorite song is Lady Gaga's Poker Face.
 * Barry is the first character to discover that Oliver is the Arrow (or the Green Arrow) in his first appearance. Other characters are Kendra Saunders, Carter Hall, Connor Hawke, Grant Wilson and Nate Heywood.
 * Despite his aversion towards intense violence and killing due to past experiences with his mother and with the Arrow, Barry has occasionally had to kill his enemies due to not having any others options to safely contain them at the time. His victims include Al Rothstein of Earth Two, Eddie Slick of Earth Two, and Vandal Savage (with Oliver Queen; though he was later resurrected). Though, as noted by Zoom, he has never deliberately killed anyone with another choice unlike Oliver.
 * Barry and Cisco have watched Star Trek II: The Wrath of Khan together multiple times. At the end, Cisco always says to Barry, "I have been and always shall be your friend".

Behind the scenes

 * Barry tends to be late for everything, a homage to the fact that in the DC comics Barry would be late for everything to keep his identity as the Flash a secret, though in the shared multiverse it's just because he is unlucky.
 * The original DC comic book version of Barry Allen has blond hair and blue eyes, whereas the Barry Allen in Arrowverse has dark brown hair and hazel eyes.
 * In the DC multiverse Barry Allen is the second person to take up the superhero mantle of the Flash, after Jay Garrick.
 * Just like his DC comic book version, Barry has a hyper-accelerated metabolism and must regularly take in a very high caloric intake to avoid losing energy and passing out. To remedy this, Cisco Ramon created a very calorie-dense series of protein bars for Barry to eat in order to avoid hypoglycemia, apart from these he also eats about 30 meals of Big Belly Burger and large Pizzas.
 * Despite Barry's Flash suit being red, when he runs at high velocity speeds, the electricity that radiates off of him is actually yellow not red, another homage to the DC comic book Barry Allen.
 * In the DC comics, Barry got his powers by being struck by normal lightning and having unknown chemicals falling on top of him. In the Arrowverse universe, Barry gets his powers from the particle accelerator enhanced lightning and being knocked into a wall of unknown chemicals, having them fall onto him.
 * Both Barry Allen and Eobard Thawne, aside from wearing masks, conceal their identities by vibrating the molecules of their faces. This is very similar to how Jay Garrick, the original Flash, hid his identity whenever his helmet fell off during The Golden Age of Comic Books (1938-1957).
 * The Streak is a name from DC Animated Universe in which the Justice League entered an alternate earth and discovered a group of superheros knows as the Justice Guild. Among them, one is named The Streak, who also utilized superspeed.
