"I know it's easier for you to think of me as a monster but I've met some of history's monsters, Raymond, and believe me, I'm not one of them."

- Eobard Thawne to Ray Palmer

Professor Eobard Thawne (c. 2151 - May 19, 2015) was a meta-human speedster from the 22nd century, a descendant of Eddie Thawne, a time criminal, and the archenemy of Barry Allen/The Flash as well as an enemy of the Legends. Obsessed with the 21st century's Flash, Eobard recreated the accident that gave the Flash his powers and became a speedster himself. But after his very first travel back in time, Eobard learned that he was destined to become the Flash's archenemy and grew to despise the hero, attempting to prove his superiority as the Reverse-Flash and therefore became the opposite of his former idol. Since then, the two speedsters battled each other for many years, but neither of them were strong or fast enough to defeat each other.

After learning the Flash's secret identity, Eobard traveled back in time to kill Barry as a child in an attempt to erase his foe but he was thwarted by the Flash of a later time who brought the younger Barry to safety. An enraged Eobard then killed Nora Allen and framed Henry Allen for the crime instead. However, Eobard lost his connection to the Speed Force, becoming trapped in the 21st century. Realizing Barry was the only way to return to his time, Eobard forged a life for himself as Dr. Harrison Wells, the director of S.T.A.R. Labs, and pushed through for the creation of a particle accelerator to ensure that Barry would become the Flash. This also caused the existence of countless other meta-humans. Posing as Wells, Eobard mentored the Flash and became the leader of a team he assembled to stop the meta-human threats, to increase his protégé's speed so that Eobard could use the hero's connection to the Speed Force to return to his own time. After his plan was exposed and subsequently foiled, he was erased from existence after Eddie killed himself to stop him.

One year after his non-existence, Eobard was prevented from murdering Nora, creating Flashpoint and held him captive for months. After realizing this mistake, Barry released Eobard, allowing him to kill Nora. As a result of being pulled out of the timeline, Eobard was spared from his fate and continues to exist as a time remnant, while his original actions remain intact. Due to his own nullified state of existence being an aberration, he is hunted by a Speed Force enforcer, forcing him to seek out the Spear of Destiny in order to restore his natural existence. Unable to find the object and outrun the enforcer at the same time, Eobard formed a supervillain alliance with Damien Darhk and Malcolm Merlyn, and later recruits a past version of Leonard Snart/Captain Cold and the reluctant Mick Rory/Heat Wave as well. Eobard and his co-conspirators eventually retrieve the Spear of Destiny, which they use to rewrite reality to their whims. Despite initially succeeding, his plan was foiled by Sara Lance/White Canary who traveled back in time and de-powered the object, and Eobard was killed by the Speed Force's enforcer as his non-existence resumed, restoring the timeline.

Despite his erasure from existance, Eobard's time remnants are preserved throughout history by the Speed Force, keeping his past time travels intact in order to stabilize the timeline (where his manipulations of it spanning years) and prevent further paradoxes.

Early life
Eobard was born in the year 2151 into an affluent bloodline of politicians, scientists, and captains of industry, and is a descendant of Eddie Thawne. A distinguished member of his own family, his first name "Eobard" is even distinguished. In his childhood, he was taught astro-navigation in grade school, and grew up with cows extinct in his time. In his adulthood, Eobard became a scientist, eventually joining the academia as a professor and dedicated his life to unlocking the secrets of the Speed Force. At some point, Eobard designed the anti-speedster rifle which would later be used by the Legends.

In his research into the Speed Force Eobard learned of The Flash, the Central City superhero of the 21st century, and grew to idolize him and eventually became obsessed with and desired to be the Flash himself. In addition to The Flash, Eobard appears quite knowledgeable about numerous other 21st century individuals and events, including history books on the Star City vigilante Oliver Queen/Green Arrow with the hero's recorded death at age 86, Malcolm Merlyn having gained the status of Ra's al Ghul at one point, and the H.I.V.E. leader Damien Darhk who tried to end the world in nuclear fire in 2016 only to be foiled and killed by Green Arrow. He also learned of the first Time Sphere (thinking that the designer was an interesting man), and several key 20th century individuals and events (such as the Justice Society of America). Eobard also appears quite knowledgeable of his family's history, even knowing of Eddie despite history having virtually no record of Eddie's existence, considering his ancestor to be a failure within the Thawne family.

After years of researching, presumably sometime in the 2190s, Eobard learned how the Flash gained these powers and recreated the accident that was originally behind the Flash's powers of super speed, resulting in Eobard gaining super speed himself and the power of time travel through a connection to the Speed Force. After gaining the Speed Force Eobard eventually traveled back in time to an unknown point and under unclear circumstances learned that he was destined to become the "Reverse-Flash", the Flash's greatest enemy and not the Flash himself. While it's unclear exactly what transpired Eobard would later speak as though the Flash had betrayed him, stating that "nothing is forgiven", and ponder of which one of them was right to hate the other. This implies that Eobard had an encounter with the Flash, possibly in retribution for future actions Eobard had yet to commit. Whatever occurred Eobard grew to despise the Flash with every fiber of his being, and made it his life's work to kill the Flash and prove his superiority as a speedster, indirectly fulfilling his destiny in the process as he descended into insanity. Eobard vowed that for everyone Flash saved Eobard would kill more, everyone who Flash was loved by, Eobard would take from his former idol. He also created a suit similar to Flash's but with the opposite colors. He also somehow obtained possession of Gideon, an artificial intelligence program created by The Flash. Eventually Eobard began searching various moments throughout history to find when Flash was active.

Grandfather Paradox
Due to the nature of the Speed Force and Eobard's erasure from existence, the exact temporal mechanism and structure behind his time travels is unknown. The following are possible phenomenons:
 * According to Eobard, the Flash he encountered before ending up stranded in 2000 was originally created by Tess Morgan and Harrison Wells's particle accelerator in 2020. Therefore, his first encounter with the Flash had to happen some time between 2020 and 2024. Specifically, the Flash was described by Eobard as a mature and veteran hero, unlike the rookie he would end up training himself. When explaining his motives to Barry Allen, Eobard was asked by Barry if they were enemies in the future, but Eobard corrected him, saying that their rivalry happened in a future, implying the possibility of alternate timelines; Jay Garrick even states that the future is constantly in motion and there are multiple possible outcomes. This concept means that the man Barry meets was from a possible future that will not exist for Barry's timeline. As Barry exists far into Eobard's past, Eobard goes back to a past timeline that does not develop into his own, as his own interferences create new possible futures. This paradox means that Eobard goes to a fixed past that his own actions develop, yet creates new futures that will never come to pass from Eobard's own experiences.
 * Alternatively, it's possible that Eobard's first travel through time triggered all his future actions that occurred across history to take effect at one, which nullified the existence of his own timeline-of-origin (where Harrison's and Tess's particle accelerator created the Flash in 2020) and trapped him within a time loop, him continuing to exist as a time remnant despite the erasure of his ancestry - thus, he always encountered the Flash in 2016 of a new timeline he inadvertently created, with all the events transpiring between the night of Nora's death in 2000 and the point in time from which Eobard and Barry travel back to the night within the timeframe of the said loop, as well as Eobard's trips back to the future. This is supported by Eobard himself telling Barry that "the reality you and I know will fade away" when the latter created "Flashpoint".
 * If this is the case then while Eobard's existence was preserved through the Speed Force as a time remnant however, sparing him from Eddie's suicide in 2015 which wiped out their family, the future of the current timeline Eobard would return to after his first encounter with the Flash should have been one where the Thawne dynasty never existed. While Eobard's time remnant would be aware of existing as an aberration, Eobard (as Wells) would later speak as though there were still other Thawnes in his time, despite being in the current timeline where they never existed because of Eddie's suicide. This would imply the possibility of Eobard as Wells's timeline-of-origin being preserved by the Speed Force and coexisting with the current one, him somehow being able to travel between them both - intentionally or not, until he caused the timeline rupture that would erase his timeline.
 * It's possible that the events of the aforementioned timeline where Harrison and Tess created The Flash in 2020 never actually occurred, and The Flash was always created by Eobard impersonating Wells in 2013 of the same timeline he would first encounter The Flash in 2016, indicating a time loop. This can be supported by Eobard's very lack of knowledge of Flash's origins, indicating errors in the historical archive, or perhaps deliberate sabotage on Flash's part precisely to preserve the nature of Eobard's time ventures. Furthermore, if Eobard is from the future of the same unchanged timeline, he would originate from a time following Vandal Savage's dictatorship of Earth in 2166 which left millions dead and the world ravaged, and could have destroyed most of the historical archive. Eobard's time remnant who remembered everything his Wells' counterpart lived through also referenced several events that neither one witnessed due to being erased, including Damien Darhk's Genesis Day plan further fueling the possibility of a time loop While this doesn't account for Eddie's suicide wiping out the Thawne family from existence it is possible Eddie may be revived which will restore said loop.

Search for the Scarlet Speedster
After learning he was to be the Flash's destined archenemy, Eobard began traveling back in time to find when the Flash was active and after several searches proved fruitless, he eventually traveled back to the year of Flash's origins, starting their war across time.

First encounter
Reverse-Flash arrived in January 2016, Central City, and after Gideon confirmed his whereabouts, he began searching for the Flash. Eobard rigged a truck to drive at high speeds and collide with a building to lure Flash out, and was successful. Pleased to have located the exact time era Flash was active, Eobard planned his return home to properly plan his next attack and broke into one of Mercury Labs' offsite facilities, and prepared equipment designed to act as a time machine to send him back to his own time. However, Eobard was unable to replicate the Tachyon power source and sought out Dr. Tina McGee.

Storming Mercury Labs and killing 4 guards, he confronted Tina but was interrupted by Flash's arrival. However, Reverse-Flash was surprised when Flash addressed him by his real name, revealing Flash already met him at some point in the future and that Flash had seen him die. However, Reverse-Flash simply thanked Flash for telling him of his impending fate, and told Flash he knew what time period he was from that he would soon die too and knocked Flash out before taking McGee to the offsite facility.

When Eobard showed his device, Tina recalled a "man in a yellow suit" tried to steal another tachyon device the previous year. Upon hearing this, Eobard realized that he'd must have gotten stuck in the past at some point in his future, and was unable to access enough Speed Force energy. Eobard ordered Tina to accelerate the energetic properties within the tachyon device. But when Tina expressed doubts, Eobard vibrated his hand and calmly told Tina to learn or die.

Vibed Timeline: After Tina finished the work at 9:52pm, Eobard killed his hostage anyway and used the tachyon device to return to his timeline. Because Cisco vibed this event 3 hours and 52 minutes in advance Flash was given enough time to locate them.

Changed timeline: After Tina finished the work at 9:52pm, Eobard prepared to kill her anyway but Flash arrived, subdued him, and destroyed the machine. Unwavered by his nemesis's sabotage to his trip home, Eobard said he would find another way to travel to the future and boasted his superiority to Flash before issuing a challenge to catch him. Both Reverse-Flash and Flash began racing throughout the streets of Central City, but Flash managed to anticipate his path and intercepted him, culminating with Flash catching Reverse-Flash. Flash proceeded to severely beat Reverse-Flash almost to death in a fit of rage for his future actions. Only reluctantly stopping himself from delivering a death blow, Flash instead knocked him out and placed him in the pipeline prison at S.T.A.R. Labs.

During his imprisonment, Eobard was visited by the young engineer Cisco Ramon, asking how his ring works. Confused yet curious Eobard talked to Cisco, and deduced he must have history with Cisco in the future, but was confused as to why the engineer wanted to know how his ring worked. However, Cisco told Eobard of being the one that found him because of powers given to Cisco by Eobard's future self. Cisco also reveals that Eobard helped build the very prison he's incarcerated in, leaving Eobard puzzled to learn of his future actions and developed an almost instant fascination with Cisco.

Eobard was later approached by Flash (unmasked but concealed in the shadows) asking his foe the source of his hatred. Eobard explained his obsession with the Flash and his desire to be the Flash himself, so much that he spent years learning how he gained these powers and succeeded in replicating them. Then he traveled through time and learned that he was going to become Flash's greatest enemy, rather than be the Flash himself, and became the reverse of everything Flash was, vowing to kill as many people as Flash saved. As Flash was disgusted to learn what was behind Eobard's motivations, Eobard angrily stated that he'd become better than the Flash, became the one thing the Flash could never stop and promises that one day he'll learn Flash's real name. Shortly after he was approached by a member of Team Flash and Eobard realized that his imprisonment has ruptured the timeline. However Eobard doubted the man knew how to send him back without Tina's tachyon device but the man had instead developed an alternate method to send him home. Fascinated with his warden, Eobard asked the man's name, but the man refused to identify himself, claiming to be no one of consequence to him yet Eobard was unconvinced and was instantly fascinated by the individual.

Eobard was released from his cell and informed of Team Flash's alternate method of sending him back to the future, to have both him and Flash run at high enough speeds to create a wormhole through which Eobard can return to his own time. Eobard also gloated of winning again, mockingly speaking in the past tense for all his future actions. As they prepared Eobard vowed they would meet again and Flash agreed but also vowed to stop him every time, and both Flash and Reverse-Flash speed around the ring of the particle accelerator. After gaining enough speed, the wormhole was created and Flash hurled Reverse-Flash through the portal and Reverse-Flash successfully returned to his own time.

Warring in the past
After his first encounter with the Flash, Eobard would subsequently go on to travel through time again and again to the early 21st century to fight his former idol. The two speedsters would then fight each other in various different times, with neither of them managing to defeat the other, though Eobard was confident that he was always one step ahead of his enemy, and described their fights as spanning over the course of centuries, implying that Flash may have also fought Reverse-Flash in his time as well. Though Eobard hated the Flash over the course of their war, he seemed to grow some respect for his nemesis, acknowledging his former idol as a veteran hero and an intelligent individual who wouldn't use time travel for selfish or foolish reasons, unlike himself.

At some point, he discovered the identity of Dr. Wells, the man who was apparently responsible for creating the Flash via a successful particle accelerator in Starling City in the year 2020, if indeed this information is true. What he didn't realize was the man he encountered in his first encounter with the Flash in 2016 was his Earth-2 counterpart. At some point, Eobard knew of Iris West-Allen (The Flash's future wife), and realized he was responsible for the superhero Vibe's "great and honorable destiny" as Eobard would be the one to give Cisco these powers one day.

Like most speedsters, Eobard also had at least one encounter with a Time Wraith which he came to fear, trying his best to avoid the creatures as no speedster knew how to kill them. Because of the dangers Time Wraiths posed, Eobard became more strategic about his timeline alterations, only making necessary alterations to achieve his primary goal, and not recklessly upsetting history and risk being found by these creatures. He also became familiar with other speedsters.

Eobard also implied that he met Felicity Smoak/Overwatch, a progeny in computer sciences, and a member of Green Arrow's team, as Eobard would later address Felicity's list of achievements as if he already knew the woman, indicating a fondness. He also might have learned Green Arrow's identity during this time. Eobard is also implied to have met Clark Kent/Superman, the Kryptonian superhero of the Earth-38 universe, as he would later speak as though having encountered such an adversary before.

Crisis in 2024
At some point in his past, around midnight on Thursday, April 25 in the year 2024, Reverse-Flash fought The Flash, 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. The speedsters 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 before Flash vanished without a trace.

Travelling to 2000
At some point in his past Eobard eventually learned Flash's real name, Barry Allen, and decided the best way to defeat his enemy was to murder Barry as a child and traveled back in time to the night of March 18, 2000, aiming to murder an 11 year old Barry, but was pursued by his archenemy. The two fought inside the Allen house around Nora Allen, each landing solid hits on each other but their skills were fairly equal. When the 11 year old Barry entered the room Reverse-Flash moved in for the kill, but Flash intervened and transported the younger Barry to safety 20 blocks away, much to Reverse-Flash's outrage. However Reverse-Flash quickly theorized another way to achieve his goal: to kill Nora and frame Henry Allen for the crime in the hopes that such a tragedy would traumatize Barry enough to derail him from his destiny, and he'd be free to return to a future without the Flash.

Stranded in the past
Reverse-Flash grabbed a kitchen knife and stabbed Nora in the heart and fled the scene to return to his own time which he hoped would now be one without The Flash, but he was stopped by his sudden loss of connection to the Speed Force. After Gideon confirmed that his powers have been drained due to his latest time jump, Reverse-Flash realized that he was now stranded in the 21st century with no way back to his time, and so screamed in frustration.

Becoming Wells
Eobard realized that the reason for his loss of connection to the Speed Force, was because his own status as a speedster was dependent upon Barry's. Therefore, if Barry never became The Flash in the past, then Eobard never would have become Reverse-Flash in the future. With this revelation Eobard realized he needed Barry to become the Flash in order to harness his speed to return to his own time. Eobard traveled to Starling City to stalk Dr. Harrison Wells and Tess Morgan. Knowing the couple's supposed important future roles in creating the Flash in the year 2020, Eobard plotted to use Harrison's reputation and his own futuristic knowledge to re-create the particle accelerator himself as quickly as possible. Eobard spied on Harrison and Tess while on a date where Harrison proposed the idea of S.T.A.R. Labs to his wife, downtown in Starling City.

Later that night Eobard rigged the road with a spike strip and caused Harrison's car to crash, killing Tess and injuring Harrison, then dragged Harrison out of the car. Identifying himself to the terrified scientist, Eobard then took out his appearance-stealing device, attached one end to Harrison and to the other to himself. He absorbed his victim's DNA and literally made himself look exactly like Wells while Harrison died in the process. After Harrison's death, he buried the body in a field near the bridge and took his victim's place in the car. When the police found him he introduced himself as Wells and subsequently took the identity. After the accident Eobard told the police the car crashed due to a tire blowout, thereby keeping Harrison's murder a secret. Eobard then moved to Central City to carry out his plan and build S.T.A.R. Labs there instead to ensure Barry gained powers, giving the cover story that he moved away from Starling City because of too many reminders of Tess.

As Wells, Eobard subsequently devoted his life to S.T.A.R. Labs' creation and its particle accelerator, using past knowledge but took precautions to ensure his plan would work and kept close observation throughout Barry's whole life by setting up cameras all over Central City even in the West house where Barry lived following Nora's death. However to avoid the attention of the Time Wraiths Eobard took precautions to avoid unnecessary timeline alterations. Eobard also came to like Big Belly Burger, considering it was one the few reasons to stay in the 21st century since cows are extinct in his time. However Eobard ultimately despised living in the 21st century deeming it "barbaric", and compared it to "living among the dead".

After opening S.T.A.R. Labs, Eobard built a secret room accessible only via hand print where he kept his belongings, including the Gideon program which was still able to stay informed of future events, including a news paper article written by Iris on the 2024 crisis. This paper acted as a deadline as to how long Eobard had to harness Barry's speed and if it changed because of time changes, Eobard would take the necessary steps to ensure the future remained on track. Eobard also kept his Reverse-Flash suit on a display case, and also stored a second suit away in the room. He also set himself up in a mansion, but he never kept any future belongings in his house itself for security reasons.

Shortly after he began construction of the particle accelerator but made some alterations first to ensure the dark matter released would spread throughout Central City, with the aim of creating a lightning bolt that would strike Barry and give him his Speed Force connection, though did not care that other people would either be killed or become meta-humans themselves. To ensure Barry's co-operation when the time came he built the accelerator to act as a sort of time machine that Barry, when fast enough, could use to go back and prevent Nora's death while Eobard used a Time Sphere to return to his time in the wormhole Barry would leave behind as a result of his time venture. To account for the possibility of Barry using his increasing speed against him instead Eobard planed to exploit Barry's speed only when Barry was fast enough to time travel not one second later, thereby giving him enough opportunity to kill him if necessary. To motivate Barry further when the time came, Eobard began working on a way to restore his own Speed Force connection through various Tachyon technologies, thus giving him significantly faster speed than what Barry's novice abilities. However, because of his own unstable connection to the Speed Force these fixes of Tachyon energies would only be temporary and would unexpectedly vanish from time to time, leaving him powerless.

Eobard observed his nemesis's life including science fairs and soccer games as an unseen influence on his life, looking upon Barry with nothing but hate but would eventually begin to grow genuinely fond of Barry (as he hated but the Flash's original future counterpart). Despite his newfound fondness, he still vowed that Barry would die. He also kept just as close observation of Eddie Thawne and took whatever precautions were needed to ensure his ancestor would continue the Thawne family bloodline, thus ensuring Eobard's existence. Through Harrison's previous connections Eobard also became associated with a younger version of Tina, though Tina always sensed something was different about "Wells" after Tess's death.

He also knew Simon Stagg, the supposed philanthropist who was famous for others' scientific achievements and knew how greedy and corrupt the man really was. Eobard also once met Robert Queen at a charity event, one of their subjects of discussion was Robert's son. In his search for promising young minds to help with his work he became aware of Felicity and foresaw "great things" from the woman. Eobard's actions had profound impacts on Barry's life both as the "man in yellow" and as "Harrison Wells". As the former he became Barry's greatest fear and driving force to become a C.S.I. with the Central City Police Department, hoping to one day find some evidence of Henry's innocence and uncover Eobard's identity. As the latter Barry would grow to idolize Eobard and was described as being obsessed with him without knowing who he really was, an ironic reverse of events as Eobard had once been obsessed with the Flash without knowing his former idol's identity either.

In 2004, Eobard was approached by General Wade Eiling to work on a military project together to create soldiers with physic abilities, presenting new opportunities financially and scientifically and Eobard agreed. While working at S.T.A.R. Labs Eobard adopted a pet gorilla named Grodd that he kept at S.T.A.R. Labs who he became close to and Grodd would view Eobard as a "father". In 2009 Eobard learned that Eiling had been using Grodd as a test subject and tortured the gorilla. When Eobard did discovered this, he cancelled the project but still had "big plans" for Grodd.

Some point prior to 2011, Eobard hired employees Dr. Caitlin Snow, Ronnie Raymond, and Hartley Rathaway. Eobard also grew especially close to Hartley during his assistance in the particle accelerator's construction. It's possible he also hired them because of his future knowledge their achievements. Eobard and Hartley often bonded through activities such as games of chess, and Hartley was the only other person who knew how to speak Latin. He also hired Arthur Light, a man who developed a lethal high powered shockwave rifle. But around 2012 Eobard fired Arthur for apparent insanity, according to Caitlin.

In 2013, Eobard discovered the Cisco of his this time and hired the youth, knowing Cisco's engineering talents (based on interactions with Cisco's future self), and started growing close also much to Hartley's dismay (though Eobard still assured that Hartley was still "his guy"). When Hartley realized the particle accelerator could fail and cause an explosion, Eobard was threatened so Eobard had Hartley fired and threatened to ruin Hartley's career if anyone was ever told. After Hartley's firing, Eobard grew closer to Cisco and came to view Cisco as a surrogate son.

Explosion of the particle accelerator
On December 23, 2013, Eobard held an event at which he planned to switch on S.T.A.R. Labs' particle accelerator, which he had created. He began speaking on stage, claiming that the particle accelerator would create a brighter future, bringing advancements in power and medicine, as well as physics as they knew it. Later that night, the particle accelerator was switched on. However particles began to behave abnormally, such as liquids floating in the air, followed by a loud bang from the particle accelerator. Eobard sent Ronnie and Cisco down to manually shut the particle accelerator down before anything bad happened.

After Ronnie had vented the system, assuring S.T.A.R. Labs' safety but sacrificing himself in the process, Cisco called Eobard down to the chamber. Eobard made his way down but not before entering his secret room and watching Barry be struck by the lightning bolt as planned, and was pleased to see his plan worked. The wave of energy from Eobard's resulting explosion also created countless meta-humans and led to at least 16 people dying. In addition to Barry, Eobard also ensured that Grodd was affected by the particle accelerator and the dark matter combined with the drugs Eiling injected years earlier activated and mutated into a hyper-intelligent gorilla and escaped the cage, though Eobard allowed Grodd to roam free in the sewers, continuing to grow in intelligence and size. He also suspected that Cisco was affected by the dark matter, due to having interacting with his future self, but could never confirm his suspicions as Cisco showed no signs of having powers.

After the explosion Eobard begun pretending to be paralyzed from the waist down not just to keep suspicion of his future activities as the Reverse-Flash away from himself, but also rigging it with a machine to feed him the Speed Force via tachyons and make him faster than even Barry and maintain his already ruptured connection to the Speed Force. After Barry was put in to a coma due to the lightning strike caused by the shock-wave, Barry's condition eventually went critical, at which point Eobard convinced Joe West (Barry's foster father) to allow him to move Barry to S.T.A.R. Labs. However, Joe was never fully trusting of Eobard and knew something wasn't right but was too desperate to see Barry awake that Joe ignored these feelings.

While Barry was at S.T.A.R. Labs, Eobard one day remarked how amusing it was to see how helpless Barry was, how easy it would be to just kill. He also remarked the irony of him going back to kill and now needing to ensure Barry's existence to return to his own time, and though remarking how interesting it's been watching Barry grow up. However Eobard firmly stated that nothing is forgiven and that one day Barry will die. Due to S.T.A.R. Labs' reputation being tarnished, Eobard ordered their Starling City branch shut down and the supplies moved back to Central City. Eobard sent Caitlin and Cisco to inventory supplies where the two unexpectedly encountered Deathstroke's army.

Working with the Flash
After Barry woke from the coma, Eobard was called down to the lab to talk to Barry. He took Barry around S.T.A.R. Labs, explaining what had actually happened on the night of the particle accelerator explosion and how they'd moved Barry. Before they could run more tests, Barry left. After having realized Barry had the ability to run super fast, Eobard and the team went to an airfield where they sought to test Barry's speed. Eobard cautioned restraint, though Barry instead ran at full pelt, accidentally running in to barrels of water. Back at S.T.A.R. Labs, Barry told Eobard the story of Nora's murder and suspected belief that perhaps there were more powered humans, perhaps like the man who murdered Nora, oblivious that Barry was in fact talking to the very man responsible. Keeping his secret safe Eobard told Barry of being most definitely unique.

Following a later run-in with Clyde Mardon's weather manipulation, however, Barry returned, angry that Eobard had seemingly lied. He admitted fault, explaining that the explosion had released various forms of seemingly theoretical energy across the city, including anti-matter, dark energy, and x-elements. Barry mentioned planning to stop Clyde, though Eobard attempted to stop Barry from taking the risk, as Barry was incredibly important in terms of scientific advancement. Despite Eobard's claims that Barry was not a hero, only simply a boy who was struck by lightning.

Though seemingly for scientific reasons, Eobard's words were clearly an attempt to sway Barry away from the heroic destiny, and exploit Barry's powers without worrying about an impending death at the hands of other meta-humans. Regardless Barry headed out to find Clyde anyway. Eobard eventually realized the only way to make Barry faster was to allow the boy to fight the other meta-humans, to push himself to the limits. As Barry struggled to unravel a tornado Clyde had made, Eobard intervened over the communication, apologizing, reassuring Barry that he did in fact believe, that Barry could undo Eobard's wrongs and succeeded in defeating Clyde. Later Eobard went into his secret room and checked up on the future and was relieved to see the future was intact.

After having acted as a hero, Barry returned to S.T.A.R. Labs, where Eobard again cautioned restraint to Barry, telling his protégé to make sure to know limits. Barry later tried to act the hero again, though he passed out. He was taken to S.T.A.R. Labs and despite being scolded, they decided to try some tests. Barry began running on a modified treadmill, causing him to eventually pass out. Eobard identified that it had to do with his glucose levels, due to an extremely fast metabolism processing it too fast. They hooked Barry up to 40 IV bags before he finally awoke. As they began discussing a new diet for Barry, Joe entered the room; Eobard was surprised to see Joe. He reassured Joe that they were looking out for what was best for Barry, though Joe disagreed that what they were doing was the way to do it. Barry yelled at Joe, causing him to get upset and leave. A while later Barry returned to S.T.A.R. Labs, having been beaten up by another meta-human identified by blood samples as Danton Black. Barry decided against trying to take him down, and despite Eobard's support, he was adamant that what they were doing was a mistake.

Following that, Eobard went to talk to Joe. He claimed that next time Barry suited up, he would doubt himself. Eobard headed back to S.T.A.R. Labs, where Caitlin was able to grow a clone of Danton Black from a replicating cell, so they called Barry in and explained this. The clone promptly awakened, presumably due to the prime Black activating some clones, and Joe hurried in through the doors, shooting the clone and reassuring Barry that only he could stop meta-humans, being one himself. They talked to Barry when he reached Stagg Industries and Eobard noted that he had to find the prime one, the original Danton Black. Ultimately, Danton was knocked over an edge, but despite being caught by Barry, forced himself to drop, killing him. The team watched a news report of it on the TV afterwards. Barry said that he tried to stop him but Eobard reflected that sometimes when people break, they can't be put back together. Following that, Eobard visited Simon Stagg. After Stagg claimed that he wanted to find and use the streak, Eobard stood up from his wheelchair and stabbed the man, claiming that The Flash (as he would one day come to be known as) had to be kept safe.

After the Darbinyan crime family were gassed to death by a presumed meta-human, the S.T.A.R. Labs team began researching what they could, all of them excited by the potential prospects. Joe noted that they would have to find somewhere to hold them, as Iron Heights was less than ideal, and Cisco suggested the particle accelerator. Cisco and Eobard went down to the particle accelerator's core chamber. Eobard had to go do some modifications while Cisco waited, using information he acquired from his own imprisonment within it in 2016. The two later assisted Barry when he went after a mist-controlling meta-human inside the Central City Shopping Mall. However, Barry discovered that the man could turn himself in to gas, and inhaled some of his toxic gasses, before racing back to S.T.A.R. Labs where the team painfully extracted the poisonous gas. The team was soon able to identify the makeup of the gas: hydrogen cyanide with traces of a sedative. Barry figured that the two would be mixed in a death row execution and they identified the meta-human as Kyle Nimbus, proudly nicknamed The Mist by Cisco. Barry went to protect Nimbus' next target, Joe, and the team supported him. Unable to outrun The Mist, they suggested he make him tired, as he would have to revert to his physical, human form eventually. Barry succeeded and Nimbus was taken back to S.T.A.R. Labs, where he was locked up in the particle accelerator prison.

Eobard defeated Barry in a game of chess while Barry also played a game of table tennis with Cisco and a game of Operation with Caitlin. When Felicity visited S.T.A.R. Labs, Eobard greeted her and was more than pleased to meet her, noting he's aware of all her accolades and that he always keeps an eye out for such talent. When Felicity questioned about the possible dangers of what Barry does, Eobard reassured her that everything they do is to ensure Barry's safety and that Barry is in good hands. Eobard was later furious at Cisco who built a weapon, a cold gun, powerful enough to kill Barry despite his speed without any consent, though Cisco built it prior to Barry waking from his coma which was stolen by master thief Leonard Snart. Eobard ordered Cisco to track down where the cold gun is and to do so immediately after telling him weapons don't belong in S.T.A.R. Labs. After Felicity left, Eobard noted she was a remarkable young woman. Eobard told Cisco to never do anything as to build such a weapon again, though he was unaware of another similar weapon that Cisco had built which was also stolen.

When a metahuman named Bette Sans Souci seemingly begun destroying facilities around the city Barry revealed that Bette was also being pursued by General Eiling, and Eobard revealed his history with Eiling. After Barry met with Bette and convinced her not to kill a scientist she had a grudge against and she was taken to S.T.A.R. Labs where Eobard and Caitlin tended to her. The team learned that Bette was affected by thermite when the accelerator went off and everything she touches explodes, and as a result she was captured by Eiling and experimented on. However Eiling himself tracked Bette there but Eobard distracted him long enough for Barry to get Bette out of the facility. Later when the team learned that Bette's condition couldn't be reversed Eobard met with Bette, and manipulated her into killing Eiling. However she was stopped by Barry and killed by Eiling but her body began building up to an explosion, and Eobard coached Barry on running on water where he dropped Bette's body in the water where it exploded safely. Later Eiling visited S.T.A.R. Labs and proposed an alliance with Eobard again but he refused and threatened his life if he ever tried to blackmail him again.

After Barry failed to stop Tony Woodward, Eobard told Barry they'd find a way to stop him, but told Barry to rest and heal for the time being. A day later, Joe visited Eobard, asking for help on Nora's murder case, ironically not knowing that man Joe was looking for was right in front of him. When Joe asked if his particle accelerator was possibly involved, Eobard reminded Joe that the murder occurred 14 years ago long before his accelerator was even thought of. After a few other suggestions from Joe, Eobard told him that they were all highly unlikely. After Barry tried to stop Tony alone, Eobard was furious as they had yet to find a way to stop him. When Barry told him that he could just heal, Eobard told Barry he can't heal if he was killed. Eobard then told Barry could stop Tony if he moved fast enough as any material can be struck at a high enough velocity.

The following day, Eobard had a drink with Joe, where Joe suggested that he was involved as Eobard arrived in Central City shortly after Nora was murdered. Eobard told Joe to look up Tess Morgan before leaving. Joe visited Eobard at S.T.A.R. Labs, having looked up Tess, and apologized for accusing him for murder. Eobard then told Joe about "his" past and why he moved to Central City as there were too many painful memories to endure. Later that night as Joe was reviewing the evidence of Nora's murder, Reverse-Flash reappeared and encircled him to make him scared, briefly allowing his suited face to be seen and stole the evidence. Before leaving Reverse-Flash left a death threat towards Iris by pinning a photograph of her to the wall with a knife, and the words "stop or else" to scare Joe away.

In an entry in his personal log, Eobard noted that Barry was driven to use his powers to help people, but stated that this was keeping Barry from realizing his full potential. He later told Barry that he had to "kick it up a notch" in his training. When Farooq Gibran attacked a transformer station Barry confronted him but lost his powers, and when Eobard went to check on the future he learned the timeline had altered. Instead of the crisis in 2024 the future now told of the permanent shutdown of the post office, and there was no record of The Flash or Barry Allen. While searching for a solution Farooq attacked S.T.A.R. Labs seeking vengeance for the deaths of his friends caused in the explosion of the accelerator, and caused a blackout that rendered the lab completely exposed to attack.

To stop Farooq Eobard theorized that Barry's cells were still altered and if they could redirect dark matter directly into him, they could recharge his cells. As Cisco worked on using the treadmill as a conduit to achieve this Eobard released Tony, offering him his freedom in exchange for killing Farooq to buy them enough time to achieve their plan though this came at the cost of Tony's life. Later, he had a brief argument with Barry about sacrificing Tony to stall Farooq, angrily insisting that he had merely done what was necessary, though Barry became disgusted that Eobard would so willingly sacrifice someone's life.

When Farooq cornered Team Flash, Eobard confronted him, reciting from memory the names of everyone who died in the particle accelerator disaster, and demanding that Farooq leave the others alone, saying that he was the only one who deserved to be punished. Farooq agreed and blasted Eobard out of his chair and while seemingly helpless to move, though in reality was faking it, Barry finally regained his speed and allowed Farooq to drain his speed once more but the amount of power overloaded Farooq and killed him, while the resulting energy fed back on him and charged uphis speed further. After Flash defeated Farooq, Eobard made another log entry, stating that he had previously been mistaken and that Barry's desire to help others was the key to developing the Flash's potential, not an obstacle as he had thought. He then took a blood sample from Blackout's corpse, whilst signaling Mist to stay quiet, saying that he was interested in finding out how the latter had drained the Flash's powers.

After Rainbow Raider robbed a bank by forcing everyone inside to go angry and attempt to murder each other, Eobard aided the team in figuring out how he did. However they were distracted by the appearance of Starling City's The Arrow who both Eobard and Joe distrusted, due to his previous body count and the terrorist attacks committed by Dark Archer and Deathstroke since he became active. Barry however defend Arrow saying he was a hero and insisted they were wrong but they told Barry to see that Arrow is out of Central City by tonight. However Barry ignored them and when Felicity visited he asked her to make him trust Arrow more, and asked for his name but Felicity refused but Eobard insisted he'll figure it out on his own. Presumably because of his future knowledge Eobard was already aware of Arrow's true identity as Oliver Queen, having once red a history book on him. Later when Barry suffered the effects of Rainbow Raider's powers he went crazy and tried to murder Eddie, and Eobard insisted Felicity call Oliver Queen, The Arrow, for help deliberately revealing his identity to Team Flash. Preparing a device to make Barry regain his senses by correcting his emotions via the colors of the emotional spectrum, Eobard and Joe arrived just as Flash and Arrow fought and used the device to restore Barry's stability. After capturing Bivolo Oliver addressed Team Flash and noted the importance of keeping his identity. Eobard also thanked Oliver for his help but as Oliver left, he felt that something was off about Eobard.

As a thank you for their help Barry gave Eobard, Cisco and Caitlin a Christmas present each, but Eobard declined Barry's offer of eggnog. To motivate Barry further Eobard planned to attack him as Reverse-Flash. A few hours later Reverse-Flash stormed Mercury Labs looking for a tachyon prototype device, killing the guards but was unable to reach the device due to the doctor sealing it away and he stormed off. Eobard "helped" Joe and Barry track down Reverse-Flash by building a trap as Joe and Barry secured the bait. Later Reverse-Flash spied on Barry as the youth talked to Iris then when Barry noticed him and ran after him, demanding to know why he killed Nora, but Reverse-Flash instead challenged Barry to a fight in a stadium. Reverse-Flash proved to be the better speedster, severely beating Barry down using several coordinated attacks, but told Barry already knew the youth's identity, that they'd fought for a long time with Barry always losing. He also told Barry it would be destiny to die at his hands, as it was Nora's leaving the young speedster very confused.

Later S.T.A.R. Labs orchestrated the trap using the tachyon prototype and lured the Reverse-Flash in, aided by Eddie's taskforce. But Eobard rigged a hologram of himself as Reverse-Flash, that would answer only to him. Once the hologram was active, Eobard, Joe, Eddie and his taskforce went down stairs to "confront" it. As Eobard addressed his hologram, the force-field appeared to fail as nobody was inside for it to stabilize, Eobard rushed into the force-field so fast that no one had time to think and were all frozen, making it look like the Reverse-Flash pulled him into the field, and trapping himself inside. In the field, Eobard created a lifelike speed mirage of himself then suiting up as Reverse-Flash in the place of his hologram and repeatedly punched his after image, making it appear to everyone else that Reverse-Flash was trying to kill him. After the field disappeared when Joe sabotaged the machine, Reverse-Flash grabs the device and takes it to his secret room then reappears in the basement, and while still bouncing back and forth to maintain the speed-mirage of Eobard. Reverse-Flash kills Eddie's task-force in seconds without any effort but hesitates when he approaches Eddie, shoving the detective to the side rather than killing (since this would risk his own existence), and attacks Joe.

Reverse-Flash reminds Joe he was warned but before he can kill him Flash intercepts him and drags him outside. However, Reverse-Flash again proved superior to Flash, but he was timely stopped by a seemingly alive Ronnie, now a pyrokinetic meta-human. Reverse-Flash vowed their fight wasn't over and ran off. Arriving back in time to take the place of his speed mirage Eobard was tended to by Caitlin and Cisco who profusely apologies for the force-field failing. Though Eobard assured Cisco it wasn't his fault he expressed annoyance towards them for not informing him of Ronnie's survival, but assures Caitlin that they will find Ronnie and bring him home. Later Eobard place the tachyon prototype on his Reverse-Flash suit and while watching it harness it's power, says "Merry Christmas" with his distorted voice as his wounds healed.

Eobard, Cisco, and Caitlin continued to train to improve Barry's speed using a drone to fire at. After Cisco called the man in yellow "the Reverse-Flash", Eobard approved of the name unlike Caitlin. After Snart returned, Barry decided to pursue Snart, though Eobard warned Barry the Reverse-Flash is a greater threat. Due to Snart's threat, Eobard and Cisco presented the CCPD with a shield that could withstand Snart's cold gun. During Barry's battle with Snart and Mick Rory, Eobard realized the best way to let Snart's and Mick's guns cross streams is to move slower.

Eobard guided Barry to detour the Royal Flush Gang. After a suggestion from Cisco, Barry, Cisco, Caitlin, and Eobard all took a group picture together. Later that night, Eobard went to his mansion and got off his wheelchair. He received a phone call and was attacked by Hartley. After Barry, Cisco and Caitlin arrived, Eobard told them he won't require their help with the case. Barry realized it couldn't have been a teenage prank and Eobard told Barry he knew who it was.

Original Timeline: After Barry stopped Hartley from attacking the Rathaway families' company, Hartley told Barry of knowing of Eobard's secret. After Hartley was locked up in the meta-human prison, Eobard asked how Hartley figured out that The Flash worked with them and Eobard was told Hartley figured out through triangulation. When Eobard was leaving Hartley taunted him by claiming to know his "deep dark secret", prompting a level of worry from Eobard. Eobard returned to his team and admitted he knew there was a chance of the particle accelerator explosion, yet choose to proceed because of the reward it could offer. After Hartley escaped the prison, Eobard ran out of his Time Vault but collapsed to the ground after losing his speed. Hartley approached Eobard and asked him if Hartley was still "his guy". Eobard later decided to regain his team's trust by publicly admitting he was aware of the chance of the particle accelerator exploding. He was then asked by Mason Bridge if he had any plans in the future of turning the particle accelerator on. After Hartley attacked the Keystone Cleveland Dam, Barry went to stop Hartley. Barry was quickly stopped with sound waves though Eobard transmitted waves through the cars at the damn, stopping Hartley. Eobard then told he wished to one day regain the trust of the team but Barry told him he already had. Later, Eobard returned to his Time Vault, reporting to Gideon that his speed comes and goes. Gideon reported that it is unsure how longer the Tachyon device is viable and Eobard told Gideon that it was only meant to be a temporary fix and the real end game was coming.

Due to a timeline change caused by Barry from 2016 most of these events have been erased and replaced by the following. Current Timeline: When Hartley attacked the Rathaway family's company, The Flash stopped Hartley. However, during the fight, the communication system in Barry's suit started to malfunction, leaving Eobard confused about what was happening but everything went well when The Flash defeated Hartley. After Hartley was locked up in the meta-human prison, Barry deduced that Hartley had EMP weapons rigged to his hearing aids which surprised Eobard when Cisco discovered this was right. Barry approached Eobard later and presented a new equation to getting faster, but Eobard was surprised to see that Barry had devised such a complex equation with Barry's knowledge in such a short time. When Barry returned after facing a threat in the C.C.P.D. Barry told Eobard and the team of the ghost-like creature that had attacked (which Cisco dubbed a "Dementor" from the Harry Potter books). But when Barry mentioned seeing the creature whilst running to stop Hartley, Eobard realized the answers to his confusion. The youth with them was from the future and the ghost-like "Dementor" was a Time Wraith who'd followed back. Eobard invited Barry into his quarters to discuss the equation. When Barry's back was turned, Eobard stood up and knocked Barry out.

Eobard took Barry, handcuffed, into the Time Vault and interrogated Barry but the youth played dumb and still addressed him as Wells, but Eobard sped in front of his nemesis and saw Barry didn't even flinch. Barry then attempts to phase out of the cuffs but fails, further identifying himself as from the future as Eobard had yet to teach his protégé how to phase. Finally Barry referred to him by real name, thus Eobard’s theory was confirmed. Barry told Eobard of needing him to teach how to get faster. However Eobard quickly realized that if Barry was alive in the future then his plan failed and tried to kill Barry, but Barry quickly claimed that Eobard did win, that he'll be successful into using Barry's speed to get back to his time. Unfortunately a singularity had formed and that was why Barry was there, to get faster in order to stop it but needed Eobard's help. Furthermore, Barry claimed that was a letter left for his younger self if something happened to Barry, detailing Eobard's true name and impersonation of Wells, how Eobard's plan worked, and how to stop him. Eobard reluctantly listened to Barry.

At the same time the Time Wraith found its way to S.T.A.R. Labs and attacked Cisco, Caitlin and Hartley but they were able to fend it off. When Cisco and Caitlin left Barry asked Eobard how to kill a Time Wraith but Eobard revealed there is no known way to kill them hence why speedsters try to avoid them. As Barry searched the police department for any clues Eobard searched S.T.A.R. Labs, but Cisco and Caitlin were unable to replicate the frequency Hartley used to stop the Time Wraith. As they debated how to stop the Time Wraith Barry of the present day showed up just as Barry of the future returned. Barry of the future accidentally begun to reveal future knowledge trying to convince the team of being from the future. To shut Barry up Eobard played dumb and pretended that he'd just met the future Barry, and told the team to prepare the particle accelerator, telling future Barry to travel through time to outrun the Time Wraith, while they build a sonic weapon to stop the Time Wraith for good when it returns in future Barry’s time along. Before sending future Barry back Eobard gave his nemesis a drive with information on increasing speed via tachyon enhancement, and future Barry successfully made it back to the future with the information he came for. Other altered events are unclear though Hartley's reformation and the slightly different circumstances of locating Ronnie appear to be the only major changes and the following events appear to remain mostly intact.

After Shawna Baez broke Clay Parker out of Iron Heights, Joe deduced Clay was a meta-human, however, Eobard corrected Joe, stating there was a woman's DNA matched with Clay's. Using the DNA, they learn the DNA belonged to Shawna. After learning Shawna's powers, Eobard told Barry they should focus on learning Shawna's limits. The following day, Eobard learned from Cisco that the latter let Hartley out of the meta-human prison, much to his disappointment. Later, Eobard learned Shawna can't teleport in dark space, as she can only teleport to what she can see. When Barry went after Shawna, he reminded Barry that she can't teleport if she couldn't see, leading to Barry busting out all the lights in the tunnel.

After Firestorm attacked Quentin Quale, Eobard told the team letting Ronnie roam free was no longer an option. Eobard deduced the reason why Martin Stein was in control of Ronnie's body was due to simple Darwinism. Eobard and Caitlin decide to have a stakeout outside of Professor Stein's home assuming Martin would be nearby to watch over his wife. While waiting for Stein, Eobard swore to Caitlin his work won't be finished until he brings Stein and Ronnie back to normal. Shortly after, Firestorm came by and the two quickly contacted Barry. While Barry and Firestorm battled, the two followed, though accidentally hit Barry as the latter fell. After learning Martin claimed he could be separated, Eobard said it was possible, but only theoretically as splitting a human and an atom were different concepts.

Eobard learned that Ronnie's body was rejecting Stein, causing an exothermic reaction and a possible nuclear explosion. Due to them only have hours before Ronnie's body detonates, Eobard suggested they may have to kill Ronnie. While the team were outraged of the concept, Eobard told them if Ronnie and Martin knew the consequences, they'd likely sacrifice themselves. In his time vault, Eobard pulled a hand gun and Gideon told him it was a crude weapon. Eobard then decided to make a quantum splicer using the tachyon device, though Eobard was told it would delay his timeline. Eobard told Gideon there would be no timeline if Central City was blown up. Cisco and Eobard built the tachyon device and gave it to Barry and Caitlin to take to Firestorm. After the splicer was placed on Firestorm, Eobard told the two to get away from Firestorm.

Eobard greeted Ronnie as he returned, thanking him for sacrificing himself to protect those around him and was introduced to Martin. Eobard then did medical work on Martin, checking if he still had the ability to harness nuclear energy. Eobard learned he was unable to and reported this to the team. After Wade Eiling attacked Ronnie, he payed a visit to the former. Eiling asked Eobard to surrender Firestorm, though Eobard refused. Later, Eobard spiked Martin's drink before conversing with him. After Martin passed out, Eobard contacted Eiling, and Eiling took Martin away. Eobard claimed to the team he was left helpless when Eiling came by to take Martin. When Barry said he would go after Eiling, Eobard reminded Barry what Eiling could do to him.

In search for Martin, the team used Ronnie as he was still connected with Stein and Eobard convinced them both to use the quantum splicer to merge against, but this time accept the balance they successfully became a more stable Firestorm. To silence Eiling, Reverse-Flash abducted him from his office and took him Grodd's home in the sewers, and revealed himself to Eiling. Upon unmasking Eobard told Eiling that he protected his own and unleashed Grodd upon him both to silence him, and for vengeance for what Eiling did to him years before.

Eobard and Cisco passed the time at S.T.A.R. Labs watching an old Buster Keaton movie though Cisco was shocked that he'd never seen it before, and Eobard sarcastically remarked "must have been before my time" and approved Cisco's request to make a list of movies to see. However Eobard also reminded Cisco of his brother Dante's birthday party but Cisco said he'd decided the best thing was to not go at all, and remarked how things had been much better since he stopped seeing them. Though Eobard was saddened to learn Cisco was still on bad terms with his family they were distracted by an alert of a break in at the Central City Morgue, though Eobard was confused as to why anyone would rob a morgue.

Identity revealed
Original Timeline: When Barry returned he told them all that Mark Mardon was the killer and was on a vendetta to avenge Clyde and Eobard deduced Mark was affected by the particle accelerator the same way Clyde was. Eobard was later told by Barry the former saw himself while running toward the morgue. Eobard told it could've been a speed mirage or an illusion. Eobard then told he would further investigate it after Mark is taken in, though Eobard seemed to be aware that Barry saw a future version of himself. A couple days later, Caitlin took Eobard to Jitters for a coffee. When Caitlin insisted they enjoy their drinks at Jitters Eobard reluctantly agreed, but noticed Caitlin was acting very nervous around him. While talking Eobard realized that Caitlin was trying to keep him distracted and away from S.T.A.R. Labs. Eobard suggested if they adjusted the S.T.A.R. Labs satellite, they could possibly pick up a storm, helping catch Mark. When Eobard told Caitlin they should go to S.T.A.R. Labs to alert Cisco, Caitlin turned around to get their coffee's in to go cups but Eobard, now positive Caitlin was distracting him, took off leaving behind his chair and revealing his deception to Caitlin.

When Cisco had just discovered a hologram was used the night they "trapped" Reverse-Flash, Eobard revealed himself to Cisco and reveals his true identity. Eobard his intent to kill the child Barry and not Nora, and revealed that he'd only been training Barry as a means to an end, as his sped was the key to returning to his time. Eobard told Cisco nothing would stop him from returning to his home, though Cisco offered help. Eobard noted Cisco to be smart, but not smart enough to bring him back. Eobard told Cisco he showed him what it was like to have a son, before phasing his arm through Cisco's chest, killing him and left the building.

Because Barry time traveled by accident for the first time and manipulated events to stop Mark Mardon, this event never occurred and instead is replaced by the following.

Current Timeline: While running, Barry stopped, confusing Eobard and Cisco and reminded him to get to the morgue but he'd claimed to have been yesterday, confusing them both. When Barry returned he told them all that Mardon was the killer and was on a vendetta to avenge Clyde and Eobard deduced Mark was affected by the particle accelerator the same way Clyde was. However Barry finished Eobard's sentence and correctly guessed almost every word Cisco and Caitlin were about to say to each other before they did, and with this Eobard realized that Barry had in fact time traveled. After learning he had traveled back one day Eobard stressed the importance of keeping history intact which meant not telling him and tells Barry that he is to repeat the events of the day again without and to not tell anyone or alter anything. Eobard checked in with Gideon but was assured the future remained in tact.

Barry however, ignoring Eobard's advice, went after Mark anyway and captured him before he could commit his crimes. Eobard, angered that Barry had altered time, reminded him that whatever tragedies he'd averted time would somehow replace it and maybe even worse than before. Eobard had Barry run at his to speed on the treadmill in an attempt to re-create the conditions that allowed Barry to time travel in the first place, but even his highest speeds couldn't achieve it. After learning that Leonard Snart had returned with his sister Lisa Snart and kidnapped Cisco, Eobard begun trying to track him down but Barry begged Eobard to let him talk about the previous yesterday and Eobard reluctantly agreed. Barry states that Mark was about to destroy the city and Iris admitted to have feelings for Barry but now she doesn't and though Barry claimed that Iris still had them, Eobard reminded him they were buried deep in her consciousness and without Mark's actions they remained unrealized. Furthermore, that Barry's powers are dangerous could cause serious havoc upon the world, though Barry knew he would have the chance Eobard suggests maybe he shouldn't since more people could die if Nora lives.

Cisco then came back to S.T.A.R. Labs, Leonard having released him but only if Cisco told Leonard who The Flash is or he'd have killed Dante and Cisco tearfully quits the team in shame. However Eobard talks to him and reminded him that choosing between loved ones is an impossible choice and regardless he is still family and Cisco stays. Later Reverse-Flash went to Central City Picture News where Mason was writing an article implicating Eobard (Wells) to the murder of Stagg and disappearance of Eiling, and attacked Mason. After learning from Mason that everything he knew about him was on his drive Reverse-Flash killed him, hid his body and fixed the office to cover his tracks. Reverse-Flash then looked at Mason's computer and noted that he really was onto him and destroyed all his evidence.

When a terrorist named The Trickster attacked the park by dropping bombs disguised as presents Eobard assisted the team in searching for a means to locate this new Trickster. However Eobard noticed Barry seemed cranky but Joe assured him that Barry was just having a bad morning. Later however when the Trickster made another broadcast Barry showed further signs of angst towards Eobard but he surmised it must be because of Barry's previous visit to see James Jesse in prison, bringing back memories of Henry's incarceration. When The Trickster uploaded a broadcast informing the public of a bomb in the city and left it's rough location Flash failed to find it, but Eobard realized it was a trick but Flash refused to listen to him much to everyone else confusion. Eobard was proven right as there was no bomb and it was a diversion so the Trickster, now identified as Axel Walker, could break Jesse out of prison and take Henry hostage.

When both Tricksters made their move to poison everyone at a fund raiser held by Mayor Bellows, Iris called Joe on his cellphone to clue him in and Eobard begun working on the antidote to the poison. However Barry had a bomb placed on him by Axel which would explode if he didn't run faster than 600 miles an hour or try to remove it, so Eobard taught Barry how to phase through a truck which separated him from the bomb and saved him. After succeeding in foiling The Trickster's plot Barry brought Henry to S.T.A.R. Labs to meet everyone where he thanked all of them for their efforts, especially Eobard. When Eobard remarked how remarkable Henry was and how lucky Barry is to have him, Barry said the same about Eobard. However Eobard knew that Barry was beginning to suspect he knew who he really was.

Eobard helped Barry investigate the strange death of Lindsay Kang at the hands of numerous honey bees, but where interrupted when Felicity arrived with her new boyfriend and aspiring superhero Ray Palmer/The Atom, seeking help on Ray's suit. After the bees took a second victim, Bill Carlisle, one of the bees followed Barry back to S.T.A.R. Labs while Barry, Felicity and Ray were out to dinner with Iris and Eddie leaving only Caitlin, Cisco and Eobard to fend off the bees. When it came for him Eobard almost broke his cover to evade it but Barry arrived in time to stop it. They shockingly discovered it wasn't a bee at all but a robot and learned the previous victims worked at Mercury Labs and paid a visit to an "old friend" Tina McGee. Dr. McGee confirmed the bees were the work of Brie Larvan but the bees went after Tina while Brie herself was sheltered some miles away, so Barry and Ray teamed up to stop Brie and the bees while Eobard and Felicity assisted over communications.

After Flash failed to catch up to a thief who could change into any person of any age Eobard became worried that this meta-human if he/she were to copy Barry, then he/she may be able to copy Barry's speed and told him to stay away from the criminal. After confirming the meta's identity as Hannibal Bates Barry and Eddie went after Bates but failed when Bates (using Eddie's appearance) goes on a killing spree. Meanwhile, Bates (disguised as Barry) infiltrated S.T.A.R. Labs and came close to killing Iris and Caitlin but Eobard figured out his deception, as he was left-handed whereas Barry was right-handed, and used a taser to force Hannibal into unconsciousness. After Joe and Cisco returned from Starling City Eobard gave his regards to Eddie and talked to Joe about his visit, but Joe questioned why he never went back. Eobard again lied and claimed it was because of Tess but reflected that they had one trait in common of being widows, regarding Iris' mother who Joe never talked about and presumed her dead as a result, and Eobard offered to have another drink with him sometime which Joe agreed to.

Eobard later returned to his secret room to ask for an update from Gideon but she assured him everything was fine, unaware Barry, Cisco and Caitlin were in the room just seconds before. Later helped Cisco and Caitlin work on a device to induce lucid dreaming, which they claimed was for physiologists dealing with people traumatized by meta-human incidents. Later Eobard called Barry and informed him of a fire in a building nearby but Flash was unable to retrieve all the civilians before the fire burnt out of control, but Eobard told him to rotate his arms at high velocities which extinguished the flames. After Eobard returned from a conference Caitlin informed him that Cisco finally figured out how the Reverse-Flash "escaped" and Eobard realized his cover was blown. Eobard instead sent Bates to pose as him and spring the trap the team had set for him as a means to get to confess to Nora's murder. After Joe killed Bates, Eobard finally dropped his facade and addresses the team over the intercom and admits to using Bates as a distraction in exchange for his freedom. Barry and Caitlin expressed their anger for ruining their lives but Eobard claimed to understand their anger, but tried to assure them that his actions have actually improved their lives. Barry then angrily tells Eobard to face him and he assures him that they will fight again, very soon.

To secure leverage, Reverse-Flash ambushes Eddie and Iris, just as Eddie is proposing, and knocks out Eddie before moving in on Iris. However, before Reverse-Flash can kill her Flash arrives and Reverse-Flash abducts Eddie instead. Reverse-Flash takes Eddie to his secondary lair underneath S.T.A.R. Labs. Upon hearing that Eddie is already aware he isn't Wells Reverse-Flash decides to reveal his true identity and relation to Eddie, answering his questions as to why Reverse-Flash didn't kill Eddie at Christmas, and informs him he is his "insurance".

To distract Team Flash, Eobard ordered Grodd to distract them using whatever means he saw fit while he constructed a device to re-power the particle accelerator, while keeping Eddie tied to a chair. While Eddie questioned Eobard's claims but Eobard stood by his pride to be a member of their family but revealed that history has virtually no record of Eddie and is considered to be the one Thawne in history that was a failure, and even shows Eddie the newspaper showing that Iris is destined to marry Barry. Later Eobard finished his device and activate the accelerator. Before leaving Eobard tries to justify himself to Eddie by asking to reflect on his own life and think of all the things that define it and what would he do if he lost everything, if he would accept his new life or get back everything he lost.

After the accelerator activates, Reverse-Flash escapes the facility with Barry in pursuit but releases Shawna as a distraction for the rest of the team. Despite Barry's efforts he is unable to keep up and Reverse-Flash escapes. Eobard returns 36 hours later when the accelerator is ready for activation, but Barry meets him outside. Eobard commends Barry's failed but brave attempt to transport the meta-human prisoners to safety, having been foiled by Captain Cold earlier after being forced to reluctantly work with him, but justifies his actions as necessary and only doing what he needed to. However, as Barry asks about his plan Eobard invites him inside but Barry doesn't fall for his deceptions, but Eobard questions Barry's plan to face him again since he failed every time before. At that moment, Firestorm and Al Sah-him (Oliver Queen), arrive and despite being outnumbered Eobard was unphased and confident he could fight them, and he engaged them all at once.

Reverse-Flash and Flash fought but Reverse-Flash manage to subdue Flash and sent Firestorm flying miles away forcing Flash to save him, but Al Sah-him was able to hit him with an arrow laced with nanites, courtesy of Ray, which disabled Reverse-Flash's speed forcing him to fight Oliver in hand to hand. When Reverse-Flash recovered he pinned Al Sah-him to the ground, taunting about Oliver's apparent original future death at age 86, and prepared for the kill only for Flash to save him and both speedsters fought above S.T.A.R. Labs. While both Flash and Reverse-Flash fought Firestorm intervened and blasted Reverse-Flash off the roof before Al Sah-him finished him off with another arrow.

Ceasing to exist
Eobard was placed inside the pipeline and after sometime Barry visited him to get answers, addressing him by his real name, and asked why Eobard killed Nora. Eobard explained his feud with Barry, the circumstances and reasoning for his murder of Nora, and that he needed Barry to become The Flash in order to generate enough Speed Force to create a wormhole though which he could return home, and in the process Barry could return to the night of Nora's murder and Henry's imprisonment thus undo Eobard's actions. Barry didn't believe him but eventually opened up to Eobard's plan and explained that his plan required using the particle accelerator, explaining that Barry would have to run at Mach-2 speed through the accelerator and collide with a single hydrogen particle. Doing so would send Barry back to any time desired and create a wormhole behind which could be used by Eobard to return to his time. However what Eobard neglected to tell Team Flash is that doing so would result in the creation of a singularity. When he was chastised he assured Team Flash they would have enough time for both to achieve their goals, 1 minute and 52 seconds, and once accomplished they would be able to close the portal.

Later while building a time machine for Eobard, Cisco visited him for advise on materials. Cisco also asked how his Reverse-Flash ring worked (reminiscent of when Eobard first met Cisco in 2016). After he told Cisco what was required Eobard became infuriated and confused that Cisco didn't have as much sympathy for his predicament. Cisco then revealed to Eobard that he'd killed his surrogate son in an alternate timeline. Eobard apologized, not for killing Cisco and justifying that he had a good reason, but to learn that Cisco had indeed become a meta-human as he'd suspected for sometime and informed Cisco that a "great destiny" awaited his protégé. Eventually Barry prepared for the jump and ran at the speed required and Eobard tutored on how to access the time Flash wanted, and successfully time jumped to the night of Nora's death.

After the portal opened, Eobard admired Cisco's Time Sphere, admitting that its original creator would be impressed. After a strange helmet arrived Eobard knew it was time to leave and bid farewell to Cisco and Joe but before he could take off, Flash returned and destroyed the pod. Enraged, Reverse-Flash asked why Flash didn't save Nora and would have had everything Barry wanted, but Flash simply told him he already did. Reverse-Flash spitefully charged at Flash and fought his nemesis. As Team Flash worked to close the portal, Reverse-Flash beat Flash into submission and prepared to kill his former protégé, vowing to kill everyone else Barry loved including Henry. As he declared his victory and dived in for the kill however Eddie shot himself in the heart, causing Reverse-Flash's body to flux uncontrollably as his existence began to fade. As Eddie's heart failed Eobard started fading out of existence as his face reverted from his Wells likeness back into his original as Eddie having just erased the entire Thawne family by killing himself before he carried on the bloodline.

When Eddie died of his self-inflicted injuries, Eobard's body begun to crack apart. Eobard arrogantly told Barry that he had controlled his life for so long, and asked how Barry'd get along without him, right before his body was incinerated and his existence erased from the timeline. However his removal from existence while his actions remained intact caused a paradox that reopened the singularity, which also served as a doorway to Earth Two. Eobard's paradox singularity also caused Ronnie's death when Firestorm was forced to help Flash to close it.

Legacy
In the event of his death where his plan to use Barry's speed to return to his own time were to fail, Eobard arranged for Barry to inherit S.T.A.R. Labs and also made the confession video to Nora's murder for Barry to give to the police for Henry's freedom. Eobard's actions continued to affect Barry even 6 months later who blamed himself for Eddie and Ronnie's deaths, for which Barry blamed Eobard for causing. 6 months later, Barry received Eobard's message. Before confessing Eobard stood his ground in saying that his former protégé will never truly be happy, but believed he himself was never really the enemy but the real enemy was in fact himself. Eobard then confesses to Nora's murder much to Barry's shock and delight. However Barry was left tormented by Eobard's words and believed maybe he was right as he'd felt a void since he failed to save Nora, and as Eobard did know Barry's future self. Eobard's future actions also dictated the actions of his younger self when he arrived in 2016 for the first time, and learned many important facts about his future he'd later exploit as Wells. While Barry did still hate Eobard for everything he did Barry eventually chose to forgive him, not wanting to hate him anymore, and later did realize that despite all he did, he truly was a father figure to the team.

Eobard's deception made Barry initally skeptical skeptical to trust Hunter Zolomon (under the guise of "Jay Garrick"). While Team Flash trusted Hunter, Barry didn't, believing Hunter too also sought to exploit Barry's speed for Hunter's personal gain just like Eobard, despite Hunter's claims of wanting to help them against the evil speedster Zoom. However Iris convinced Barry that not everyone is Eobard and to not be distrusting people because of that experience. While Barry listened to Iris and soon began to trust Hunter, Barry would later discover that Hunter actually was Zoom and was there to exploit the Flash's powers for his own use, thus Barry blamed himself believing Hunter's façade and should have known better after Eobard's actions as Wells.

As Eobard's various actions completely destroyed Harrison's reputation to the public with the truth of his deception known only to Team Flash and several of their allies, this made it hard for his identity theft victim's alternate-reality doppelgangers. Team Flash were skeptical to trust Harry Wells of Earth Two, believing Harry too was evil like Eobard. However Team Flash continually ignored the fact that Eobard wore the face of Harry's Earth One counterpart, a fact that Caitlin seemed to remember while Harry was forced to continually reminded of. Barry was ironically more open minded to trusting Harry than the rest, especially Cisco and Joe, despite Harry's face was a reminder of Eobard's betrayal. Over time, Team Flash realized that Harry is inconsiderate and blunt but wasn't evil like Eobard was. Because Eobard's destroyed reputation caused as Wells, Harry often found himself targeted by other people who weren't aware of the deception. This included Patty Spivot shooting Harry with only Hunter's timely intervention with the use of Velocity-6 saving Harry's life, and Harry later kidnapped by Griffin Grey mistaking Harry for Eobard trying to force to develop a cure for the meta-human condition. While Team Flash was more open minded about welcoming HR Wells of Earth Nineteen to the team, Eobard's actions as Wells also made it equally hard for HR to be seen in public. HR was highly irritated that Team Flash neglected to be informed of Eobard's façade beforehand. Unlike Harry HR was able with a facial transmogrification device to be disguised Randolf Morgan to remedy this problem caused by Eobard.

Flashpoint timeline
When the Reverse-Flash grabbed a kitchen knife and attempted to stab Nora, he was attacked by another version of the Flash from 2016, viciously knocking him down. Refusing to let Reverse-Flash kill Nora, and refusing to let him ruin anyone's life ever again, the Flash knocked the Reverse-Flash out, radically altering the future and undoing many of Reverse-Flash's future crimes. Flash then took Reverse-Flash back to the new version of 2016, took his ring from him, and constructed a speed-dampening cell using carbine material to imprison him in an abandoned factory. Barry made frequent visits to Eobard to give him food. Unfortunately for both speedsters, Barry's intervention created an entirely new reality all together. Due to Barry creating a new reality than what they knew, Eobard was aware Barry's memories would fade in order to adapt to the new timeline. However simply for amusement Eobard kept this to himself wanting to see how long it would take Barry to realize this himself, but was unsure as to why he wasn't losing his own memories. Eobard would remain imprisoned for over three months, eventually getting a bearded look. When Barry visited him again to deliver Big Belly Burger, Eobard jokingly named the new timeline "Flashpoint", and still promised to destroy Barry's world. However Barry didn't take Eobard's words seriously and reminded him he had everything back that Eobard and Zoom stole from Barry and was finally whole (having saved Nora and Henry), but Eobard told Barry that Flashpoint is nothing more than a mirage, and it's effects will end them both unless Barry lets him correct what been done. Eobard also remarked how selfish Barry was being after being told there was another individual who was the Flash in this timeline, letting someone else endanger themselves' in pursuit of Barry's own happiness. However Barry simply scoffed at Eobard's words and reminded him that Barry changed time because of what Eobard did to him, but Eobard stated that once Barry started to feel the effects, Barry would beg him to kill Nora "again". When starting to lose memories Barry returned to question Eobard, relieved to see his nemesis was finally feeling the effects. Eobard explained to Barry that the new reality was beginning to overwrite the reality they were familiar with, and soon Barry wouldn't remember his original life. When Eobard was asked why he wasn't losing his memories he replied that he wasn't sure, but he finally realized why after a few moments. The more Barry used speed the faster Barry'd lose memories, and since Eobard hadn't used his speed at all his memories remained intact, laughing hysterically at this ironic revelation. However Barry believed Eobard was trying to manipulate into releasing him from his cell.

Eobard then frustratingly remarked that the Flash he knows and fought for years is far more intelligent than Barry is now. Eobard stated that soon Barry will forget being the Flash and neither of them will be able to fix reality, that time would set permanently like concrete and not be able to be changed again. Barry told Eobard being fine with it but Eobard pleaded that he needed to take him back to 2000 and correct what was done, that Nora's death needed to happen in order to make things right. Barry spitefully told him to go to hell, but Eobard angrily retorted that his nemesis's arrogance would take them both there. As Barry left Eobard angrily yelled "Now who's the villain, Flash?! Now who's the villain?!".

Barry returned later with Iris, having finally realized Flashpoint is too dangerous to continue living in, and agreed to release Eobard, though Eobard forced Barry to state why in words, as Barry did so expressing hate while Eobard simply returned the same expressions, questioning whose anger is justified. Eobard was then released and given his ring back. As Barry started to fall unconscious, Eobard expressed his desire to just kill his nemesis before telling Barry that this time he got to be the hero, and hauled Barry through the Speed Force and returned to 2000 moments after Flash and Reverse-Flash's younger selves had fought for the second time. Arriving moments after the younger Flash had knocked out his past self, the current Reverse-Flash taunted past Flash while trying to assure that Nora was ok, saying that actually Nora wasn't. As a result, the younger Flash and Reverse-Flash dissipated as the current Reverse-Flash grabbed a kitchen knife and stabbed Nora in the chest, correcting the major changes to the timeline.

Altered reality and being hunted by Black Flash
Rather than restore the timeline however Reverse-Flash's actions had created another newer timeline where most of the Pre-Flashpoint events remained intact, though a few events significant to Barry were altered. Being pulled from the timeline, Eobard's existence paradoxically remained intact and he also retained vague memories of his life as Wells. After returning Barry to 2017, Eobard, no longer sporting his beard as Flashpoint had been erased, claimed that everything was back to the way it was, at least for him, but tauntingly told that Barry's present wouldn't be the same and would have to simply wait and find out. When Barry asked him what he meant, Eobard appeared pleased to have tormented his foe yet again and simply said he would see him sometime soon, speeding off to an unknown time and place.

Shortly after however Eobard found himself pursued the Black Flash, a black-clad demon-like speedster who now serves as an enforcer of the Speed Force. Whilst initially mistaking Black Flash for a Time Wraith Eobard quickly realized the monster after him was far more dangerous than any Time Wraith he'd encountered. As a result, Eobard was forced to keep running through time and space to avoid the monster. Eobard eventually realized that the enforcer was after him because Eddie's suicide had erased him from existence in 2015, but because of Flashpoint and Barry bringing him to 2017 after restoring the timeline when he's not supposed to exist, he now existed as a time remnant, and Black Flash was trying to kill him to eliminate the paradoxical threat and restore the ruptured timeline.

Searching for the Spear of Destiny
Realizing he couldn't run from Hunter forever, Eobard set out to locate the Spear of Destiny, a mystical weapon foretold to have the power to re-write reality itself to restore his own existence to the timeline. However the spear was divided into several pieces and guarded by members of the Justice Society of America from 1956, and Time Master Rip Hunter, scattered throughout time. To find it Eobard required the Askaran Amulet, a compass detailing the locations of the other spear pieces and their respective guardians. However Eobard discovered the compass itself was divided into two pieces but Eobard discovered one half was in possession of Nazi Germany in 1942 while the other half was in the possession of the Soviet Union in 1987.

Aiding the Nazis
First he traveled to 1942 and began secretly aiding high-ranking members of the Nazi party to obtain the first half of he amulet, providing them with future information and the means to win World War II in exchange for it. During this time he encountered the 1942 version of the Justice Society of America and had several encounters with its leader Rex Tyler/Hourman, and met the Legends, a team of time travelling heroes who were trying to prevent the achievement of his plans. During Reverse-Flash's last encounter with Hourman he discovered Reverse-Flash's plans and was instructed by Rory to take the Waverider to 2016, and stop the Legends arrival to 1942 and prevent Reverse-Flash from achieving his plans before they begin. While Reverse-Flash tried to stop Hourman the Legends opposed him and while Reverse-Flash succeeded in killing all of them, their sacrifices bought Hourman enough time to pilot the Waverider through time to complete his mission. To stop his plans being exposed to the Legends, Reverse-Flash traveled back further in 1942 to start his plans over, erasing his past actions but also erasing the Legends' deaths.

Realizing he couldn't stop the Legends, find the amulet and outrun Hunter all at once Eobard was forced to seek out partnerships with various individuals to have them find the amulet pieces for him, promising to alter past or future events for them, while he kept outrunning Hunter. Eobard's first candidate was Damien Darhk, the leader of H.I.V.E. Eobard hired Damien to join Adolf Hitler's plan to build an atomic bomb and destroy New York City, in the hopes the Legends would perish trying to prevent it.

Aberration timeline: The information Eobard provided with Damien aided in Adolf Hitler's plan to kidnap Albert Einstein and force him to develop an atomic bomb, which would destroy New York City. The aftermath of this would also cause World War II to end October 8, 1947 instead, and would cause the death of an additional 12 million more people. This caused an aberration, resulting in a time quake that alerted the Legends as planned.

Fixed timeline: Damien succeeded in constructing the bomb by kidnapping Mileva Maric instead of Einstein, and forcing her to build the bomb. However, as planned the Legends were forced to use the Waverider to intercept the bomb, and they were scattered throughout time. As a result, Eobard's plan succeeded as he had drastically altered the Legends first encounter with Hourman. When a German officer tried to kill Damien after refusing to help him build another bomb, Reverse-Flash slayed the U-boat's crew members before he and Damien greeted each other.

To obtain the first half of the amulet without interference this time Eobard began working with Baron Krieger and met with him in Paris. Krieger told him the amulet was in Berlin though Hitler refused to part with it. Eobard presented a sample his newly developed biomolecular enhancer, which could be used to create an army of super-soldiers to oppose the Justice Society of America. He also claimed it would let Hitler plant his flag above the White House within months. Eobard gave Kreiger a small dose for one person for him to confirm the serum's properties, promising to deliver the means for mass production, but only if he obtained the amulet. Reluctant, Kreiger agreed and Hitler arranged for the amulet to be transported to Eobard's custody.

While Kreiger did obtain the amulet, he was intercepted and killed by the combined efforts of the JSA, Legends and the United States Air Force while in route to Eobard and the amulet fell into Hourman's possession. Reverse-Flash later attacked Hourman at the JSA's headquarters. Reverse-Flash told him of their previous history, as Hourman in this timeline hadn't met Reverse-Flash yet, and his plan to stop the Legends. He then phased his hand through Hourman's chest. As Hourman bled to death Reverse-Flash stole the amulet and sped off before Amaya Jiwe/Vixen came into the room. Killing Hourman at this point also caused his older self in the original timeline who'd arrived in 2016 to warn the Legends to fade out of existence before revealing Reverse-Flash's plan, only succeeding in warning them not to travel to 1942.

The Legion of Doom
Eobard then traveled to 1987 to retrieve the other half of the amulet and aided his "old friend" Damien as he was about to caught by members of the DEA while trading drugs with dealers in exchange for a relic. Eobard offered Damien a partnership to aid him in his plans in exchange for rewriting his own destiny. However Damien initially refused but Eobard warned him he knew of his plan and it's outcome and promised that he could give Damien actual power, rather than symbols of power. Interested, Damien agreed and Eobard had him arrange a meeting with the Soviets to obtain the second half of the amulet. When the Legends confronted Damien at his deal Reverse-Flash traveled there to stop them from killing him and risk losing the amulet.

Just as Sara Lance/White Canary had taunted him about the ultimate unlucky outcome of Darhk's plans for H.I.V.E., Eobard sped Damien out of the facility. When Damien realized that Sara had snatched his relic, he demanded Eobard to take him back, but the speedster reminded him the Legends had left the time period and were beyond reach. Damien then reconsidered Eobard's offer and begged him to take him back to his next destination, insisting he needed to change his destiny. Accepting his answer, Eobard showed him a Time Sphere and when Damien was inside Eobard sped around it to open a portal into the Speed Force where he traveled to his next destination with Damien.

Eobard and Damien then traveled to 2016 to recruit Malcolm Merlyn/Dark Archer, the former Ra's al Ghul and former leader of the League of Assassins. Eobard sped himself and Damien into Malcolm's apartment, as he had descended into alcoholism after losing the League of Assassins and H.I.V.E. following Damien's death in 2016. Malcolm was highly confused to see Damien alive as he'd just watched Green Arrow kill him on the news but Eobard elaborated that he was from the future, and Damien was from the past, and they were on a quest to change their fates and offered Malcolm the opportunity to do the same in exchange for his services. While skeptical at first Malcolm agreed and accompanied the duo through time. Following this the trio traveled to the ruins of the former Time Masters base of operations in the Vanishing Point and began using it as their own base.

Chicago trap
Planning to cause an aberration to lure the Legends out and retrieve the Askaran Amulet Eobard's team traveled to 1927 and offered their assistance to crime lord Al Capone.

When they approached Capone he initially refused and tried to have them killed Eobard slaughtered his men, and Capone listened to his proposal. Eobard would ensure Capone would remain out of police custody and become mayor of Chicago. In exchange Capone would aid them against the Legends. Intrigued Capone agreed. As per their deal and part of the plan Eobard informed Capone that he was destined to be apprehended by Prohibition agent Eliot Ness, and Capone had Ness abducted and plotted to kill him. As planned the Legends arrived and foiled his plan. As the Legends searched one of Capone's clubs for evidence against him, Eobard abducted Sara and Professor Stein. Eobard had Stein brought to him and used the appearance-stealing cord on him, planning to infiltrate the Waverider and find the amulet himself.

Taking Martin's place, the Legends came to his "rescue" though Eobard had Capone attack them to avoid drawing suspicion. On board the Waverider, Eobard began searching for the relic but could not find it and was soon stopped when Sara came to speak with him about Martin's daughter as an aberration. However Eobard, having no knowledge of Martin's daughter, questioned her claims leaving her suspicious. Then Nate Heywood came into the library asking to speak with Sara about Jefferson Jackson though Eobard insisted Jax could wait, though Sara immediately noticed him refer to him as "Jax" and not "Jefferson" as Martin had a tendency to do.

Realizing Nate was aware of his deception and was trying to warn Sara, Eobard attacked them, dropped the disguise, and sped off. In the hallway he was subdued by Jax with a speedster weapon but Eobard quickly recovered and attack Jax. Before he could kill him Atom attacked him, but before he could finish him Eobard sped off towards the bridge and sealed himself within. Dropping the ship's cloaking technology, Eobard opened the cargo bay doors and allowed Malcolm and Capone's men on board to kill the other Legends as he continued searching for the relic. Finding Mick with a bag of valuables he believed Mick was trying to steal Eobard believed he'd found the amulet but realized too late Mick tricked him, and was blasted from behind. Eobard was surprised to see Rex's lover, Amaya, was his attacker and attacked her. Before he could kill her though Eobard was alerted that Black Flash was close and sped off to avoid him.

However Malcolm had managed to force Sara to give up the amulet in exchange for Stein's location. By the docks Eobard elaborated the amulets were in fact one in two pieces as Malcolm pointed out to a confused Damien, displaying a holographic compass. However Malcolm initially mistook it for a "portable planetarium" much to Eobard's annoyance. Elaborating that the compass was a guide to finding the Spear of Destiny to a confused Malcolm and Damien. Eobard informed them finding it would be complicated but the first step is locating the former leader of the Legends; Captain Rip Hunter, one of the protectors of the spear.

Locating Rip in 1967, Eobard sent Malcolm and Damien to capture him so they could acquire his piece of the spear while Eobard went on the run from Black Flash. After managing to outrun him and escape, Reverse-Flash returned as Malcolm and Damien fought the Legends, and swiftly knocked them all to their feet. As Eobard questioned who should die first Rip revealed himself and pulled a gun on them, only for it to be a film prop which amused the Legion, unaware Rip was suffering amnesia. After the Legends retrieved the spear piece they retreated to the Waverider but Eobard swiftly kidnapped Rip before the Legends could retrieve him. Taking Rip their facility Eobard demanded he tell him about the spear but he claimed not to know anything, and had Malcolm and Damien torture him to make him talk.

Hunt for the Spear of Destiny
As his patience began to wane, Eobard was informed by his associates Damien and Malcolm that torturing Rip would not work because Rip literally couldn't tell where the Spear was as his memories had been wiped. Infuriated, Eobard derided them for losing the medallion and violently accosted Malcolm when he and Damien pointed out that Eobard was responsible for losing it too. Malcolm reminded Eobard that he needed them and suggested using hypnosis on Rip. However Malcolm's methods failed as Rip's memories had been wiped too thoroughly. Eobard exasperatedly remarked on the results of working with a washout (Malcolm) and a dead man (Damien) and sped off. Later when Eobard returned Damien had successfully extracted on of Rip's teeth which had a barcode symbol for a back account in 2025 Zurich, Switzerland which Eobard theorized must contain the rest of the spear. At that moment, Eobard's watch began to sound an alarm, prompting Thawne to order Damien and Malcolm to take the Time Sphere back to 2025 before running off without an explanation.

Having outrun Black Flash, Eobard arrived in 2025 Zurich just in time to find his associates having successfully broken into the bank vault and discovered that Rip's box contained a Mnemonic Archive which held Rip's memories. As he examined it, Malcolm suddenly sealed the vault door, trapping them all inside and declared that he and Damien were going to re-negotiate their deal with Eobard, starting with him revealing why he needed the Spear and why he was always running out on them. While Eobard amusingly threatened to kill Malcolm he was unable to as he was the only one who knew the vault door code, while Damien chose to simply watch. As his associates started questioning him more Eobard's watch alerted him to Black Flash's presence. Visibly scared, Eobard begged to be let out or they would be killed. When pressed about who by his associates, Eobard finally told them about Black Flash trying to kill him hence why he keeps vanishing. Satisfied, Malcolm and Damien resolved to help Eobard escape his pursuer.

The trio set up an ambush in the bank with Eobard as bait to draw the dark speedster in, though Eobard was able to remain invisible to it by not using his speed as it raced throughout the bank searching for him. As the spectral speedster was about to zero in on him, Malcolm and Damien attacked Black Flash from both sides, distracting it long enough for Eobard to use a speed-punch to send Black Flash hurtling into the back vault, at which point Eobard sealed it inside. Know that his enemy would not be contained for long, the trio departed the bank but not before Eobard acknowledged Damien and Malcolm as his fully equal partners.

After escaping, Eobard used the Mnemonic archive to restore Rip's memories, but reprogrammed his mind and made him the fourth member of his syndicate, and sent him to 1776 to kill George Washington on Christmas Day to cause an aberration to alert the Legends and lure them out. Eobard and Rip then traveled back a few days earlier and Eobard made an alliance with the British army promising to ensure their victory in the American Revolutionary War, in exchange for their assistance in retrieving the spear. To aid the British Eobard also supplied them with 21st century assault rifles which Rip presented to a platoon of British soldiers entrusted under his command. Pleased to see Rip's reprogramming is successful Eobard entrusted him to retrieve the spear piece from the Legends and succeeded.

After this, Rip told Eobard about the other fragments being in the possession of the JSA and each period of where they were. Eobard then sent Rip to Chicago in the year 3000 to retrieve another spear piece from Dr. Mid-Nite, and succeeded and killed him in the process. Eobard then sent Rip and Damien to Camelot in the year 503 to retrieve Stargirl's piece though unfortunately Rip was captured and the spear piece lost to the Legends. Learning that Commander Steel hid his piece within the Apollo-11 flag pole on the Moon itself Eobard himself traveled to 1970 and posed as a doctor for NASA, to see one of the astronauts, John Swigert, one of the astronauts meant to go on Apollo-13's mission to the moon. Eobard took the man's appearance and place on Apollo-13 and ventured into space. However since Eobard repaired the oxygen tank that was meant to explode he caused an aberration that alerted the Legends. After Apollo-13 was in space Eobard knocked the other astronauts out and dropped his Swigert disguise and made the preparations for landing. However he discovered Atom has sneaked aboard and they fought, though Eobard was unable to use speed in zero gravity, but Atom managed to beat him and tied him up.

After Ray got the fragment, he learned that he had to use the LEM to get back to the Waverider but it was damaged. Eobard told him that he could help Ray repair the LEM and offered a temporary truce, which Ray grudgingly accepted. As they moved to repair the ship, Eobard told Ray that it was nice to work with a fellow scientist again reflecting on his times with Cisco and Caitlin. He also informed him that it was easy for Ray to see him as a monster but he had seen history's greatest monsters and he wasn't one of them. Ray scolded him for his claim as he'd killed Nora twice, killed Hourman and brainwashed Rip into killing Dr. Mid-Nite. However Eobard said that they were more alike than he would admit as they were both scientists that chased after the impossible and that Ray didn't have to be ashamed of reaching for higher feats. They managed to take off and re-connect with the Waverider and Eobard was quickly thrown in the brig. When the Waverider had to enter the atmosphere without the aid of Gideon, Ray went to Eobard to find out the correct angle to enter without burning up. Eobard told him the angle instantly and told Ray that he would have to trust him as he wanted to live just as they did.

When the Waverider managed to land safely, Eobard phased himself out of the cell easily to look for the spear pieces but was quickly met with Ray who had a speedster weapon ready. He laughed at the irony as he was the one that invented the weapon in the first place. Ray told him that he knew that he would try and escape, and was aware he is a time remnant because of Eddie's death, and something was after him to try and correct the aberration. Eobard confirmed his suspicions as his watch alerted him that Black Flash was close, and Ray told him the'd have no time to search the ship. Eobard smirked at him and told him that they would meet again before he sped off.

After failing to retrieve the last fragments of the spear, He sent Malcolm and Damien to get the Calebros Manuscript in order to activate the spear to rewrite reality. While he was making a plan to try and track the Legends, he discovered that they'd infiltrated the Vanishing Point and stolen their two fragments of the spear and fled before Eobard could stop them. When Damien returned and learned of what happened he scolded Eobard for his recklessness, but Eobard realized that now that the Legends had all the fragments, they no longer had to hunt for it piece by piece. However, Damien insisted that in order to succeed, they would need to up their strategy besides just the three of them. Eobard then traveled back to 2014 and located Snart before he had joined the Legends and turned from his criminal ways. They told him of his future death and he agreed to help them in getting the spear. After Leonard successfully manipulated Mick into betraying the Legends and steal the spear from them during World War I, Eobard sped into the war-zone and transported Leonard, Darhk and Mick to the Vanishing Point. After Malcolm return with the Celebros Manuscript the five Legion members held onto the spear as Malcolm read the incantation and they began to use its power to re-write reality to their whims.

Rewritten reality
In this rewritten reality, Eobard remains in 2017 but is now the official C.E.O. of S.T.A.R. Labs with world-wide recognition. He is also a close friend of the President of the United States. However, Eobard did not remove (or perhaps could not remove) the Black Flash from the new reality. Regardless, Eobard built a dampening cell in S.T.A.R. Labs that he kept Black Flash imprisoned in, leaving the demonic speedster unable to escape, running around the inside of his cell in murderous rage, with Eobard commenting that he wants to somehow bend the speed demon to his will, to no avail. As per his agreement with the Legion, Eobard also altered their fates based on their desires.

First Eobard revived Malcolm's wife and son, improved his relationship with Thea, ensured Nyssa al Ghul was living a "miserable closest life in Ohio" and made Malcolm C.E.O. of Merlyn Global Group and Ra's al Ghul once more. Eobard then made Damien the Mayor of Star City and restored Damien's magic who then killed many vigilantes who opposed him, including Barry thus finally ridding Eobard of his archenemy. This also led to several other heroes' deaths including Oliver, John Diggle/Spartan, Rene Ramirez/Wild Dog, Rory Regan/Ragman, Evelyn Sharp/Artemis, Vigilante, Laurel Lance/Black Canary and a vigilante Felicity Smoak. Finally Eobard improved Leonard and Mick's lives and while they remained criminals as they desired, the police allowed them to carry out their thefts without interference though they carried out assassinations for Eobard when called for.

He also changed the fates of the Legends as retribution for their interference in his plans. He kept Rip stuck inside a powerless Waverider which was shrunken down and put on display on his desk, driving him insane with nothing else to do but bake cakes. He made Jax and Martin employees at S.T.A.R. Labs and made Jax a much crueler individual who was often abusive towards Martin, who was not permitted to leave S.T.A.R. Labs until his projects were completed and sometimes remained there for months. He also made Ray a janitor at S.T.A.R. Labs. He also reduced Nate to being a conspiracy theorist that no one believed while living with his mother, and turned Sara and Amaya into Damien's personal assassins. To ensure nobody could reset the new reality Eobard destroyed the manuscript and had Martin work on developing a fusion reactor equivalent to the power of the sun, intending to incinerate the spear entirely.

As he considered his partnership with Malcolm and Damien over he ignored any calls from them. Eventually Malcolm confronted Eobard in person as there were still some things he wanted changed, but Eobard insisted that the spear was best kept in his possession as he was the only one who knew how to use it. They were interrupted by Jax informing him the reactor was taking longer than anticipated but Eobard, calmly made subtle threats to motivate him. After leaving Eobard broke into a hard laugh as Malcolm scolded him for keeping the Legends around as pets when they should be erased altogether, though Eobard considered it poetic justice. Eobard then told Malcolm to leave and enjoy his new life as he, frustratingly, left. Fearing Malcolm may become a problem he asked Leonard and Mick to keep an eye on him. Before they could go on further Nate arrived past security, having no knowledge of Eobard, and told him reality was't right. Realizing Nate was starting to catch on to their actions he ordered Leonard and Mick to take him away and kill him. Later Eobard checked up on Martin and he completed the reactor though Eobard insist he remain behind until it reached full power. However Eobard was alerted by Martin via silent alarm of intruders. Reverse-Flash sped into the lab to find Martin confronted by the Legends, having successfully restored their memories. Reverse-Flash annoying mused at this revelation before unmasking and holding the Spear of Destiny over the reactor, ready to throw it in. Eobard annoyingly remarked that Malcolm was right before also being confronted by the Legion who demanded the Spear of Destiny. Eobard tried to tell the Legends and Legion that he was trying to destroy the Spear of Destiny for their sake but Leonard abruptly shot him with his cold gun, rendering him unconscious.

Eobard awoke as the Legends and Legion fought over the spear and tried to re-obtain it, only for Nate to use it on him sending Eobard flying across the room and knocking him out again. Eobard awoke again after Leonard just killed Amaya as she attempted to use the Spear of Destiny and took it back, and tossed it into the reactor and destroying it. While the Legends and Legion both expressed desire to kill him Eobard was unwavered by their words as without weapons or powers, they're hopelessly outmatched against his speed. However Eobard did not wish to see the Legends dead, not out of sentiment, but rather to watch them suffer as they remain trapped in the new reality where everything they've ever accomplished no longer matters. He also allowed the Legion to live despite their mutiny, but promised to kill them if they tried to oppose him again. Telling all of his opponents to remember this mercy of his, he ordered them to leave the premises of his laboratories.

Ceasing to exist again
Shortly after the Legends managed to restore Rip and the Waverider to size and traveled back to 1916 to stop the Legion from obtaining the spear in the first place, by altering the events of their past selves thus erasing their present day selves from existence. Anticipating this Eobard traveled back to 1916 and as Atom re-discovered the blood of Christ Eobard stole it, and crushed it. Remarking that the Legion was right about disposing of his enemies Eobard phased his hand through Atom's chest, and removed his heart and amusingly watched as Atom died. Later Eobard found Merlyn as he searched for the manuscript and brought him back to 1916 and met with Leonard and Damien. Explaining he was from the future where they had retrieved the Spear of Destiny and altered reality Eobard told them of the Legends plan and instead of deceiving Mick as planned, ordered them to attack the Waverider and take the spear by force. As the trio did this Eobard went to get back up and created dozens of Reverse-Flash time remnants.

Returning after the Legends defeated the Legion, though they'd still succeeded in killing the older versions of Jax, Nate and Mick, Eobard and his Reverse-Flash time remnants arrived and encircled them. After they refused to hand over the spear the Reverse-Flashes attacked them, killing the older Rip in the process, and Eobard stole the Spear of Destiny from the younger Sara as she attempted to rewrite reality. Taunting Sara over her failure Eobard promised to erase them from existence but the spear wouldn't power up, and Eobard realized that Sara already used the spear to erase it's own powers rendering it useless. Enraged, Eobard tried to use it to physically kill Sara instead only to be confronted by Black Flash, due to the fact that he was never trapped in STAR Labs as Doomworld never existed because the Spear of Destiny was neutralized, as well as Eobard having carelessly left his warning device in Doomworld. As Eobard panicked he attempted to flee only for Black Flash to swiftly catch up and phase his hand into Eobard's chest, stopping his heart. After doing so Eobard's existence ceased yet again, along with the Spear of Destiny, and he helplessly screamed. After being erased the Reverse-Flash time remnants also ceased to exist.

Personality

 * -|Younger years=

In his first encounter with the Flash, Eobard was petty, somewhat short tempered and unstable. When Barry found out Eobard's hatred was because he couldn't be just like the Flash, Barry expressed disgust, causing Eobard to snap, yelling that he's "become better than" the Flash, arrogantly stating he's the one person Barry can't stop. This trait can be further seen in his murder of Nora Allen after Barry's younger-self is saved from danger (though he reasoned that he did that to try and ward off Barry from becoming the Flash).

Though polite, Eobard is also shown to be rather arrogant, self-righteous, overconfident, somewhat cruel and sadistic. During his first encounter with the Flash, these traits were evident, Eobard believing the Flash couldn't keep up with him. Despite his superior speed, the Flash outsmarted Eobard, beat him unconscious and imprisoned him. Upon meeting Cisco for the first time, Eobard was impressed by Cisco's powers, even curious, maintaining politeness for the most part. However, he still smirked with sarcasm when Cisco taunted him of his imprisonment. Eobard is also shown to take great joy in mocking his enemies for the fall-out of their own actions, demonstrated when Harry Wells came to free him and send him back to his own time so as to repair the damage to the timeline.

Another notable personality trait is his deep and insatiable hatred for the Flash. Eobard admitted that he used to be a huge fan of the Flash, going as far as to find out how his hero came to be and how to become like the man, even succeeding in gaining super-speed himself. But realizing that he was fated to be his idol's greatest enemy caused him to go insane with hatred and rage, to the point he was determined to erase the Flash from existence, even going as far as to kill Barry as a child and killing Nora when he failed to do that, partly out of rage but partly out of his strong desire to ward Barry off from becoming the Flash.

Eobard tends to justify his murders by stating that all those whom he had killed had already been dead for centuries from his perspective. In particular, he has used this rationale to justify his murders of Nora and Tess Morgan. In reality, Eobard couldn't care less about his victims, seeing how he killed them out of convenience, despite those acts harming the timeline. According to an older Eobard, he once felt rage every time he looked upon the Flash, a hate shared by his adversary.

"I know that rage. I used to feel that rage every time I looked upon you. And now, somehow, I know what Joe and Henry feel when they look on you with pride. With love."
 * -|As Harrison Wells=

- Eobard Thawne to Barry Allen

Under his Harrison Wells façade, Eobard is a scientific genius responsible for numerous achievements in the scientific field and had a large sense of respect from the scientific community, as was the very genius behind the particle accelerator's existence. After finally being able to orchestrate the accident behind Barry Allen's powers, Eobard was presented with Barry, helpless, lying in a coma, so easy to kill. While observing Barry's coma, his anger at the Flash became evident, when he began vibrating his hand threateningly as his voice slowly became a furious hiss.

However, despite Barry lying beside him completely helpless, Eobard refrained from killing Barry, knowing that the Flash was needed for him, if the time traveler ever wanted to return home, but still claimed that "nothing was forgiven", vowing that he still wished to kill Barry as soon as it was possible. Whether Eobard changed his mind later on is unknown.

Eobard was a character of dual-identities towards his team and himself as he openly appears caring and compassionate, guiding Barry's journey of becoming the Flash, but had been shown to be willing to kill to ensure Barry's safety, and willing to sacrifice the meta-human prisoners to ensure this protection. Eobard was also willing to sacrifice other people as he activated the particle accelerator after being warned of its possible malfunction at the risk of the city, all to ensure Barry would be struck by the lightning bolt to turn into the Flash. Though seemingly caring and compassionate towards Team Flash, he also did appear somewhat tortured, a combination of "losing" his "wife" Tess and the number of people killed because of his accelerator.

He is shown to be a very secretive man, as not neither Cisco Ramon nor Caitlin Snow had ever visited his house, and had either killed or manipulated people to their deaths. He did, however, seem to care about Barry's life, as he nearly gave up his own secret to rush to Barry when he chose to take a missile head on, instead of running from it. He was also willing to confront Blackout, in a bid to divert from attacking Barry, Cisco and Caitlin, and spurring the return of Barry's powers. He also protected Grodd from being tortured by Wade Eiling's inhumane experiments. Despite at first being tempted to kill Firestorm, Eobard decided to help separate into two people again. This can be either from the fact that killing Ronnie Raymond and Martin Stein would cost Eobard the trust and respect of Barry, Cisco and Caitlin or the fact he genuinely had a change of heart.

Eobard is a man of sophistication, it's unknown if he was raised in this manner of upbringing, or if it was another thing he had picked up from Harrison, in any case he is a man of the finer things in life, such as his own private collection of scotch, showing an interest in classical orchestra and was able to fluently speak in Latin, a trait he shared with his former protege Hartley Rathaway.

When his real personality is shown to Team Flash, after abandoning his Wells identity during his time under that persona, Eobard stated that everything he's done has made his own team's lives better, despite the fact that he had been selfishly using Barry to get back to his own time, and both Cisco and Caitlin were pariahs from the particle accelerator incident. This shows, even after 15 years hiding behind a different identity, he remains a self-righteous sociopath that tries to justify his immoral actions.

Eobard remains somewhat sadistic and unstable, shown by his numerous threats to Iris West and the rest of Barry's loved ones whenever his plans start to fail, attempting to kill seemingly on a whim. He also continues to take great joy in mocking his enemies for their vain attempts to stop him and not understanding his plans, demonstrated when Team Flash thought Hannibal Bates was him. Though he continues to justify his murders by stating that all those whom he had killed had already been dead for centuries from his perspective, shown with his killing of Cisco, he expressed a bit of remorse for some of these murders, though it wasn't enough to dissuade him from returning to his time by any means necessary.

In addition to taking on Harrison's complete genetic makeup and physical appearance, Eobard also ended up taking on some of his victim's personality traits, particularly the love for Tess as Eobard admitted. This love supposedly affected him to the point that he even admitted to feel like he would burst into tears when thinking of Tess and the fact that he was Tess' killer. Also Joe West rationalized the reason Eobard was willing to go so far to return to his home and time, even committing acts of murder, identity theft and espionage, was because he deeply loved the people and life he had back home - a love not unlike what Joe had for his children, namely Barry and Iris.

Due to hiding behind his Wells identity, adapting and evolving every situation to better suit his agenda under his disguise and being Wells himself for fourteen years, Eobard has become even more skilled at plotting and manipulating since he time-travelled, coming close to believing his own lies. But he is not flawless in his deceptions and though he is able to fool those who know him to an extent, Tina McGee, who were said to have been "thick as thieves" as the real Harrison's close friend, could detect that he became a "different person" ever since Tess's death. He presents himself as a kind, humbled benefactor, even that is extensive to what situation better suits his multi-layered personality and he is more than capable of acting ruthlessly pragmatic to one which requires such behaviour, even in front of Barry, Cisco and Caitlin at times. Up until his true nature was revealed, he rarely killed directly but preferred to silently bend others and systematically destroy any threats to his designs or life using his vast intelligence. In moments of desperation or with no foreseeable alternative than violence, he would have no problems with threatening or straight-up murder.

As long as none of his "friends" knew his secret, he treated them like they were his own children. Before Barry changed the timeline, Eobard wanted to keep Cisco from finding out most of all because he wanted to avoid killing Cisco if necessary. But when Eobard found out he killed Cisco in that alternate timeline, he stated he didn't care nor was he sorry for it because he was certain he had a good reason for doing so.

For the most part, Eobard hated the Flash and was originally tempted to kill younger Barry, seeing his protégé as little more than a means to an end. However, he grew to care for Barry, having looked after and raised him as a student, and in some ways, even as a son. When exposed as the Reverse-Flash and trapped in the Pipeline, Eobard even stated that he could understand and empathize with the paternal love that Joe and Henry Allen had for Barry. Though Barry was initially disgusted by Eobard's words and wanted nothing to do with them, Barry later admitted Eobard may have been genuine. In spite of this, Eobard's hatred for Barry seemingly resurfaced when Barry reneged on their deal, which included Barry going back in time to save Nora and Eobard returning to his home in the future - this was evident when Eobard violently pummeled Barry just before vowing to kill not only the Flash, but Barry's friends and Henry too. Although he seemingly calmed down shortly before fading from existence, he still used his last seconds to mock Barry about how his nemesis would get on and survive without him there to control.

In his will, though Eobard stated that Barry would never truly be happy, implying that his disdain for Barry may have never died completely, yet he also acknowledged that the two of them were never truly enemies and that it was not he who Barry truly hated. As a favor, he was going to give what Barry wanted: a confession to his guilt in Nora's murder, which would free the unjustly accused Henry from prison - and allowing Barry to inherit S.T.A.R Labs officially, but only after watching the video first. This final, posthumuous act shows that in spite of all his villainous traits, Eobard does have honor in him, and in spite of his very complicated feelings about the Flash, which still included resentment and a desire to be on top of the Flash even in death, showed that he on a certain level genuinely cared about Barry's well-being.

Eobard was also very laid-back about what happens to him, though this usually happened when he believed that his plan will not be affected. Even when confronted with the combined forces of the Flash, the Arrow and Firestorm, Eobard showed absolutely no signs of fear or concern and instead smirked, remarking "this would be fun". It is probable that Eobard was holding back the entire time and was planning on being thrown into the pipeline anyway, so he could gain S.T.A.R. Labs' full cooperation with helping him return to his time.

Eobard's calm, laid-back attitude to dangerous situations against his own life actually hid decades of pent-up rage and hatred. After discovering the only way to return to his timeline was to create the Flash, a man who he felt pure loathing for in its entirety, he found the situation almost laughably ironic claiming it was fate's way to spite him one last time as the only reason he traveled through time was with the sole purpose of killing his so-hated archenemy and with these plans in array, it would contribute to Eobard's already vast anger, causing him to snap out on Barry and threaten to kill the whole of Team Flash and Henry.

Suffice it to say, Eobard as Wells had an extremely complex psychological makeup, with an adaptable and malleable nature. He ranged from being a self-focused and egotistical sociopath of the highest order, to a truly compassionate and honorable man in his later years, albeit with a very twisted sense of honor. Overall, he was a very morally gray man, much less the monster that many people tend to see him as, and had shown himself as a very tortured man, cursed to fight his own hero and become his enemy. Ultimately, his motivation for all the good and evil he has done throughout fifteen years was claimed to be a return to his old life as Eobard Thawne in the 22nd century, to leave the "barbaric" 21st century and come back to the people he cared about. Since it was all for naught, with Eddie Thawne erasing the lives of the Thawne family that was supposed to come after him, this burden of reuniting Eobard with his century fell onto the next version of Eobard, one that survived erasure by reversing Flashpoint.


 * -|Post-Flashpoint=

Trapped and imprisoned in an alternate timeline version of 2016 (which Eobard dubbed "Flashpoint") by Barry Allen, Eobard has shown contempt and ridicule toward his heroic counterpart. His hypocrisy came through as he called Barry out for being "the villain", despite Barry only changing the part of timeline that was wronged by Eobard's time travel in the first place, when ironically, his future self as Wells was gonna let him save his mom as part of his endgame. Eobard's more twisted and demented demeanor was turned directly against Barry, with him stating he would take great pleasure tormenting his nemesis, for the timeline to be "restored", despite the "true timeline" also being a product of Eobard's machinations.

Eobard's hypocritical nature showed itself further in his attempt to erase Rex Tyler from the timeline, which altered Rex's encounter with the Legends in 2016. Despite blaming Barry, Eobard implied that he clashed with Rex in multiple variations of the timeline, yet did not care for the damage to the timeline that killing Rex preemptively would cause.

After traveling through the Speed Force to 2016, Eobard somehow gained memories of the life his other self lived through in the new timeline, shaped by him masquerading as Harrison Wells since the year 2000. Eobard would claim to have fond memories of his work alongside Caitlin Snow and Cisco Ramon, commenting that he did not see himself as an absolute monster, especially in comparison with monsters he has witnessed throughout centuries that he's seen through time travel.

Unwilling to let anything stand in his way, Eobard would cause multiple historical aberrations for the Legends to clean up on his quest to find the Spear of Destiny, being so low on morals that he was ready to provide Nazi Germany with his meta-human biomolecular enhancer that could allow the Nazis to win the war, all just to get a part of the Askaran Amulet from Baron Krieger. Eobard has also shown a willingness to work with various terrorists, such as Damien Darhk and Malcolm Merlyn, and had zero compunctions about helping Damien double-cross the Nazis in 1942, slaying them all with his own hands. Furthermore, according to Damien, it was Eobard who had him be a part of Adolf Hitler's plan to nuke New York City in the first place, for no discernible reason other than the possibility of gaining an artifact from Hitler.

Armed with the knowledge of the future(s), Eobard would show great pride and cockiness, creating an aura of the all-knowing mastermind around himself. He's shown it both to his enemies, implying to Martin Stein that a version of him knew the Professor, and to his allies, goading his "partner" Damien Darhk for more than forty years before finally revealing the possibility to change Damien's unlucky fate, and acting condescending towards Malcolm, amused at Malcolm knowing the Askaran Amulet's lore, despite him seeming like nothing but a "pretty face" to Eobard. However, he would also show himself eager to tell the others of his knowledge of history and myths, detailing how the Amulet would help his allies find the Spear of Destiny. Despite his arrogant and overconfident traits, Eobard is not without fear, as shown when he was pursued by the demonic enforcer of the Speed Force once known as Hunter Zolomon, now described by Eobard to be a beast worse than even the Time Wraiths. He was shown to be in true terror of the beast when describing it and when he took part in attempting to bait Zolomon into a trap.

Eobard would often toy with his enemies, the Legends in particular, showing them how easy it would be for Eobard at his full power to slaughter them all. He directly threatened to kill Jefferson Jackson, but was stopped by Ray Palmer. For one reason or the other, Eobard seemingly tries to keep the Legends alive deliberately, in particular since he modified his appearance-stealing cord to allow its victims, such as Martin Stein, to stay alive, a courtesy that he would not show to the innocent Harrison Wells. He even showed mercy to the rebelling Legends and Legion members in the new reality that the Legion created, though he claimed that this was not out of sympathy but simply to serve as a means of punishing their defiance by forcing them to be trapped, powerless, in a timeline that they tried to change, but only for the worst. Proud of his decision, Eobard told the mutineers to "remember this mercy". However, this arrogance worked against him as it gave the Legends a chance to reunite with Rip and the Waverider to travel back and undo Thawne's reality reset.

Eobard has also shown a more contemplative, philosophical side. When he taunted Barry and was met with another declaration of hate from Barry, Eobard replied that he, too, hates the Flash, and yet sometimes he wonders just which one of them is in the right, implying some hidden reasons for him to hate Barry that are much more grievous than those claimed by his younger self.

Despite the fact that his actions would be characteristic of a remorseless sociopath, Thawne's time remnant would still show a certain degree of humanity. With the knowledge of his ancestry and own mortality, the new Thawne now wanted not to best the Flash, but simply to continue living, something that he mentioned while trying to get sympathy from Raymond Palmer while the two were stranded on the moon together. Eobard even acknowledged that it is understandable for him to be thought of as a monster by heroes like Raymond, but he does not consider himself as such, having previously met history's worst monsters. When he did rewrite reality, Thawne successfully stopped global warming, the melting of ice caps and the extinction of the polar bears. As he previously told Dr. Palmer, Thawne greatly enjoyed working with Caitlin and Cisco at S.T.A.R. Labs, which is why he engineered a reality where he could still lead S.T.A.R. Labs without having to pretend to be Harrison Wells.

Powers

 * Speed Force connection/Meta-human physiology: Replicating the circumstances that created The Flash's powers, Eobard Thawne gained access to the Speed Force, albeit his connection is actually the opposite in nature compared to the Flash's. Thus, his physiology has been greatly augmented to beyond peak human performance, letting him handle extreme physical exertion and performance. His powers as the Reverse-Flash make him arguably one of the most powerful characters known, with only the Flash capable of rivaling him.
 * Accelerated healing factor: The Speed Force in someone's blood gives it regenerative properties. Eobard's body heals much faster and more efficiently than a normal human. His wounds from being attacked by the "Man In Yellow" were completely gone without a trace afterwards, which he covered up by isolating himself to avoid speculation of any kind. After being viciously pummeled by the Flash in 2016 he was able to recover as if he had never been hurt.
 * Accelerated perception: Eobard's speed also extends to his senses and mental capacities. He can take in information and process it at much faster rates than a normal human, as well as see and hear clearly when moving at super-speed. This ability allows Eobard to see the world as if it is in slow motion, which, combined with his physical speed, lets him perform thoughts and actions long before a normal human around him could even perceive them. When Barry was running at mach 2, Eobard was able to follow these movements with ease, and does this again when Barry travels to the past under his guidance.
 * Bodily vibration/Intangibility: Eobard has the ability to vibrate any part of his body at different frequencies on command, with varying effects. When done, this is seen as a haze that normal people can't perceive clearly. It can also garble his voice into a deep growl to disguise it. He can also seamlessly phase his arm through a person, killing them instantly without outwardly damaging them. As Cisco Ramon remembered his own death at Eobard's hands despite it being erased from time, Cisco described Eobard as having crushed the heart with his fist. By vibrating the cells in his body, Eobard can pass through people or objects unharmed. This ability appears to have damaging effects on electrical equipment, as it shorted out Mason Bridge's computer. By vibrating rapidly, Eobard was able to reverse the effects of the modified appearance-stealing cord, which the device could also do for him with a push of a button.
 * Electrokinesis: As a speedster, Eobard can produce powerful red electricity from his body. The intensity of his lighting is so great that the moment he arrived at the stadium for Barry's first fight with him, the electrical lights and video screens around it started glitching and flashing. Eobard is also capable of making his eyes glow bright red, which most likely is another effect of his electrokinesis.
 * Enhanced strength: Reverse-Flash has displayed a degree of enhanced strength, exerting inhuman amounts of force without using his speed. From a stationary position, he was able to throw The Flash into S.T.A.R Labs' sign several yards away with one arm. He was also seen punching Mason which made Bridge go all the way up to the roof and as the man came falling down he once again punched his victim, making Mason go all the way across the room. As means of intimidation and/or restraining, he has repeatedly been shown able to easily hold down, or even pick up, a full-grown adult with a single hand, usually by their necks. He was also was able to effortlessly break a man's neck from behind while protecting Damien Darhk in 1987.
 * Superhuman agility: Eobard possesses inhuman bodily coordination, balance, equilibrium and dexterity. He is able to change direction immediately, thus allows him to make sharp turns on city streets without sliding or losing his balance.
 * Superhuman durability: Eobard's durability is well-above that of human, able to endure attacks and exertions much quicker than normal and survive impacts that would be fatal or at least permanently disabling to normal humans. He was able to both withstand and quickly recover from pyrokinetic blasts from Firestorm on multiple occasions, being shot with multiple of arrows, and being pummeled by Barry, who also has enhanced strength and momentum. During his fight with Flash, Firestorm and the Arrow, he also hardly fazed after falling from S.T.A.R. Labs' roof to land from several stories up unfazed by moving at super speed at the same time.
 * Superhuman speed: Eobard is able to move at levels of speed well above Mach 2.2, easily outpacing Barry Allen's limit during 2014-2015. Using this speed, he can easily move on vertical structures and ceilings. Barry said that he's so fast that he could kill everyone in the police precinct in seconds. His tremendous speed was later revealed to be greatly influenced by tachyon particles in his body. As revealed by Caitlin Snow, this allows Eobard to with each stride his feet spend less time on the ground, thus propelling him forward much faster, similar to Zoom with the Velocity serums. He is later shown to be able to effortlessly beat the Legends. However, he's not fast enough to escape from the Black Flash in their final showdown.
 * Aerokinesis: Using his speed, Eobard can generate air flow as vacuums on various levels. He can create fierce waves and vacuums of air by shaking a body part very fast. His speed vacuum is very powerful, as he was able to blow Firestorm blocks away by rotating just one hand.
 * Speed mirages: By using his speed to bounce back and forth so quickly, Eobard can create after-images with his speed, making it appear like he's in two places at once. This image is so realistic, human mind can't perceive the difference.
 * Superhuman momentum: The Reverse-Flash can generate an inhuman amount of physical force from any part of his body, especially while using super speed. This allowed him to exert inhuman physical strength with almost absolute ease, commonly to restrain opponent at super speed and pinning them down with little effort, as well as to kill his opponents through high-speed collision. By channeling this force to his strikes, even The Flash was quickly pummeled and rendered unable to fight back despite healing powers. When he faced the Black Flash in 2025, Eobard punched it with enough force to send the creature flying through several rooms before slamming against the far wall. He could also punch clean through people, as he did do impale Bridge on his arm and even to punch through his chest-piece of the A.T.O.M. Exosuit to tear out the Atom's heart from his chest.
 * Time travel/Chronokinesis:  Using the Speed Force, speedsters such as the Reverse-Flash are able to conduct chronokinesis, or temporal manipulation, which allows him to travel throughout time. Unlike other speedsters, Eobard is eventually able to freely travel throughout time with little to no effort. Because of his connection to the Speed Force and his previous travels through time, he is able to travel throughout time without causing serious ramifications to his existence. This has also allowed Eobard to continue existing despite his ancestor Eddie Thawne killing himself.
 * Time remnant construct: By shifting momentarily back in time, Eobard is able to "create" a time remnant. As each one is as real as the other, it allows Eobard to overwhelm his enemies with multiple copies of himself.
 * Superhuman reflexes: Eobard's increased speed also augments his reaction time, allowing him to react to danger and events far faster than a normal human.
 * Superhuman stamina: Eobard's body can handle the stresses of superhuman racing without noticeable distress. His body's enhanced stamina allows him to function much longer than a normal human without getting tired or weak. Therefore, he is also adapted to the extreme amounts of force exerted on him while he is moving at super speed, as well as the extreme temperatures and lessened amount of breathable air.

Abilities

 * Expert computer hacker: Eobard's shown to be a skilled computer hacker, being able to hack into the radio signals of multiple cars in order to destroy Hartley Rathaway's weapons.
 * Genius-level intellect/Great business acumen/Master tactician/Manipulator/Leader: Eobard was considered a genius in the more advanced era of the late 22nd century which makes him potentially more intelligent than most if not all individual of the early 21st century. He has a superb knowledge of meta-human biochemistry and molecular structure, creating a biomolecular enhancer. He has also shown in-depth knowledge and understanding of time-traveling like the Time Masters. With this, he was able to effectively evade any encounters with a Time Wraith and confidently travel back over 150 years to change the past with no fear of affecting his own future, as well as to give the Legends trouble balancing the timeline. Eobard is a great tactician, as evidenced by him coming up with plans to help Barry Allen defeat the meta-humans. He managed to for nearly a year to prevent Barry's team from figuring out that he is the Reverse-Flash. Eobard is a capable manipulator, he managed to manipulate Tony Woodward and Hannibal Bates into helping him. Eobard is a skilled business man, as evidenced by the crucial role he played in Team Flash and creating the particle accelerator. Eobard managed to run S.T.A.R. Labs very successfully for 14 years, until the particle accelerator explosion incident caused the company to shut down. Eobard was later able to run S.T.A.R. Labs again after rewriting reality with the Spear of Destiny, having become a prominent figure in the world of business. He is also skill with contingency plans. Despite losing to The Flash, The Arrow, and Firestorm, set in place the necessary tools to force everyone to go back into the pipeline of S.T.A.R. Labs.
 * Occult knowledge: He also has knowledge relating to mystical artifacts. He knew that the Askaran Amulet was a Judeo-Christian artifact which acted like a compass for the Spear of Destiny as well as knew the Spear's divine capabilities. He even related some knowledge of the Fasces Axe which Damien Darhk was purchasing.
 * Master engineer: Eobard has shown to be very proficient in the art of engineering, being able to recreate the tachyon device into a Quantum splicer for Firestorm with Cisco, creating a ring which compresses and stores his suit, using futuristic technology to reactivate and modify the particle accelerator as well as creating his own Time Vault. Eobard also managed to modify the appearance-stealing cord to be nonlethal to the person whose appearance is being mimicked, however, it still caused the victim a great deal of pain, as this happened with Martin Stein.
 * Skilled hand-to-hand combatant: Though suffering a beating at the hands of the Flash from 2016 in his first encounter with him, Eobard eventually became an expert hand-to-hand combatant, fighting on par with the Flash of the future. Whereas the novice Flash from 2014-2015 relied primarily on speed to overwhelm slower opponents with random striking, the older Eobard was shown to be a very methodical fighter, striking at precise spots to systemically wear down his opponent. He easily defeated the younger Flash from 2014-2015 in multiple fights. Even when his speed was temporarily deprived, he was shown to be able to temporarily hold his own against decent fighters like Oliver Queen and Ray Palmer.
 * Speed Force expert: Eobard is shown to have great intelligence about the Speed Force and its usage. He has many times helped and guided Barry to use it better. He knew it has powers to create vacuums, move seamlessly pass through any solid target and was able to direct Barry on how-to use the Speed Force to time travel. He also used it fluently in combat, much better than Barry initially was able to due to a greater experience. He's also revealed he knows about time remnants, when he went up against the Legends.

Weaknesses

 * Anti-speedster weapons: The Legends have an arsenal of anti-speedster guns, invented by Eobard himself, which would allow the user to momentarily slow Eobard down. However, Eobard showed himself resistant to the weapon, restoring his powers after mere moments.
 * Nanites: When he was shot with a nanite arrow, Eobard lost his powers for a short amount of time even though Oliver said it'd take away his speed for "quite awhile", and he could somewhat vibrate, allowing him to phase the nanites out of his body, instantly restoring his powers.
 * Residual tachyon energy: When Eobard accessing the Seed Force near liquid, it floats in the air, giving a hint that he is present. This is caused by tachyons he is exposed to when working with them, helping him run faster. It can also be caused if Eobard has recently moved through time, as tachyons usually have this effect when around time traveling speedsters who have used this power or where temporal distortions have been, causing massive change in time and having marked the area to have tachyons.
 * Time alterations: While willing to make huge leaps through time and likewise meddle with events, Eobard still has a great respect and fear of time manipulation done recklessly. This is from fear of both undoing his own future and the existence of the Time Wraiths who act as guardians to the Speed Force's energy. Even more while existing as a time remnant as his past self was erased from existence, Eobard was forced to constantly run, even through the timeline itself, to avoid getting killed by the relentlessly hunting of the Black Flash, of which Eobard was utterly terrified of facing.
 * Irregular levels of gravity: Eobard is unable to access his speed while in space or on the moon. While Ray suggests this is because of the lack of gravity, Eobard is still unable to phase or vibrate himself while tied up on the moon, which does possess a gravitational force. However, this may simply be because of the differing gravitational forces of Earth and the moon, meaning that Eobard would be able to phase in that particular level of gravity. Also, he needed to manually restore his normal appearance with the appearance-stealing cord instead of vibrating on his own power. He can however still access his speed and phasing abilities to its fullest abilities when Earth-level gravity is artificially replicated (e.g. on the Waverider).
 * Extreme cold: Much like other speedsters, Eobard seems to be weakened or at least momentarily stunned when exposed to an extremely cold environment. This was proven when Leonard Snart's Cold Gun knocks Eobard unconscious for a short period of time.
 * Mortal wounds: Despite his accelerated healing, he can still be killed by massive damage done to vital organs like his heart or brain. This was seen when Black Flash drove a hand through Eobard's chest and impaled his heart, killing Eobard and erasing him from existence as well.

Former weaknesses

 * Speed Force connection flux: While originally having access to the Speed Force similar to Barry Allen, Eobard severely damaged his connection to the Speed Force from having traveled back in time to kill Barry as a child, due to altering the youth's future destiny as the Flash and damaging Eobard's own past. While later regaining his super speed and most of its related powers, he still lacked a proper connection to the Speed Force, rendering him unable to travel through time and stranded in the distant past. At the same time, his recovered speed was unstable, randomly working, and also appeared to effect his ability to work. To compensate somewhat, Eobard relied on the tachyon prototype to stabilize his powers for longer durations. However the version of Eobard that now exists after Flashpoint never experienced these damaging event and thus is able to use his powers to their fullest with ease.

Equipment

 * Earpieces: On his suit's cowl, there are two lightning-bolt shaped earpieces, also similar to those on Barry Allen's Flash suit.
 * Gideon: Eobard uses Gideon, an advanced artificial intelligence created by Barry Allen, to aid him during his travels through time.
 * Reverse-Flash ring: Eobard owns a ring with a Reverse-Flash lightning-bolt symbol on it that can open secret rooms within S.T.A.R. Labs. He uses it to open up a wall that contains a mannequin which his Reverse-Flash suit is draped over. Eobard is able to hold his entire costume in his ring, and shoot it out of the top, allowing him to change into it at super speed and always have it ready for wear.
 * Reverse-Flash suit: Eobard wears a protective suit while acting as the Reverse-Flash, to hide his identity from his victims. It is similar to the Flash's future suit, but only reversing the colors (red to yellow, white to black).
 * Various future technologies: Eobard has several devices and gadgets from his time at his disposal. Some have been displayed and their functions have been shown, though there are those that are still unknown.
 * Appearance-stealing cord: This device has two cords that are connected to two organisms, corroding one while transferring that one's genetics (especially phenotypes) to the other, allowing the survivor to physically resemble the other in every way. Eobard used this to physically become Harrison Wells but also gained his victim's memories and love for Tess Morgan. After Flashpoint, Eobard modified this device (or an identical one) to be used without killing the person he uses it on, only causing the victim pain, and allowing him to revert to his normal appearance when he wishes so he is not trapped with any one appearance. Eobard used the modified device on Martin Stein and others during his quest for the Spear of Destiny.
 * Biomolecular enhancer: Eobard gave this to the Nazis in 1942 as a bargaining chip in a trade with Adolf Hitler. It was used to mutate Baron Krieger into der Übermensch. Ray Palmer modified Eobard's enhancer into a drug to cure Nate Heywood's hemophilia. As a result, Nate also received meta-human powers of his own identical to Tony Woodward's.
 * Watch: Eobard has a futuristic watch which can indicate whenever the Speed Force enforcer is near.

Former equipment

 * Tachyon device: After his connection to the Speed Force began fluctuating, he stole this device from Mercury Labs, using it with the intentions to get faster and stabilize his fluctuating Speed Force connection for longer durations. However, once the effects of this device could no longer help him, he converted it into a Quantum splicer for Firestorm.
 * Wheelchair: After the particle accelerator exploded, Eobard pretended he became paralyzed in his legs to hide his identity from the team. In addition, a device was stored on the underside of the wheelchair that was charging his super speed which Cisco Ramon eventually discovers. After his identity was revealed to Team Flash, Eobard abandoned this wheelchair which is currently in S.T.A.R. Labs.

Trivia

 * Eobard's bloodtype is AB-Negative.
 * As noted by Cisco, Eobard shares a similar fondness for movies with him. He appears to be a fan of the Back to the Future film trilogy, the film Ghostbusters and implies he's seen It's a Wonderful Life. However he also claims to have never seen any Buster Keaton movies even in his time.
 * As Wells, Eobard seems to have a liking for food from Big Belly Burger as cows are extinct in his era and has an interest in curly fries. Interestingly, he shares this love for Big Belly Burger with Harrison's doppelgängers (Harry Wells and HR Wells), implying he inherited this fondness from Harrison's DNA. Yet he is shown to have a liking for 'curly fries' in Flashpoint, a timeline in which he never stole Harrison's appearance.
 * The electricity that radiates off of the Reverse-Flash is red for unknown reasons. He is one of the few speedsters to have red lightning (the others being Edward Clariss and Hunter Zolomon after becoming the demonic enforcer of the Speed Force). It's possible that his lightning is red due to having an artificial connection to the Speed Force.
 * Even after Eobard was revealed to be an impostor, his former allies still have a habit of referring to him as Wells (sometimes "Evil Wells" or "the Other Wells"), even after several encounters with his younger self prior to adopting Wells' appearance. This often annoys actual Wells counterparts.
 * Ironically enough, it is revealed that Eobard Thawne is the one that invented the Anti-Speedster rifles kept by Rip Hunter on the Waverider, and he went on to become a speedster himself.
 * It is stated that Eobard was a match for Barry's speed in the year 2024.
 * Eobard has been erased from existence twice both while attempting to kill another major Arrowverse protagonist. First he was erased by Eddie's suicide while trying to kill Barry and second by Hunter while trying to kill Sara.
 * Eobard is the first main Flash villain to be killed by another main Flash villain.
 * While Eobard is responsible for numerous individuals becoming meta-human criminals he is also indirectly responsible for numerous individuals becoming meta-human vigilantes outside of Barry. These include Cisco Ramon/Vibe, Firestorm, Dinah Drake/Black Canary, Jesse Quick and Nate Heywood/Steel.
 * Thawne is currently the only character to have been a regular on two different Arrowverse series (The Flash and Legends of Tomorrow), as well as the only character to have been the main antagonist for two different seasons (The Flash Season 1 and Legends of Tomorrow Season 2). However, on The Flash he was predominantly portrayed in his "Wells" disguise, while he was almost entirely in his true form on Legends of Tomorrow.
 * On Cisco’s blog, Chronicles of Cisco, Post-Flashpoint Eobard Thawne appears as one of the suspects of being Savitar. How Cisco knows this is not explained, but it's presumed he saw him when he vibed the Flashpoint timeline, or a still existing alternate timeline of it.
 * Ironically, Eobard's time remnant was killed the same way he killed Cisco, Mason Bridge, and threatened to kill many others, including Malcolm Merlyn. By having the Black Flash phase his hand into Eobard's chest, stopping his heart.

Behind the scenes

 * In DC Comics, Eobard Thawne is Barry Allen's greatest enemy, operating under the alias "Professor Zoom", also known by the title of "the Reverse-Flash". After Flash: Rebirth storyline on New Earth, and a later one in Prime Earth, Eobard was depicted as the man who killed Barry's mother.
 * Unlike his comic version, Eobard Thawne is never referred to as "Zoom" or "Professor Zoom", but only as the "Reverse-Flash". In the comics Eobard Thawne is the second Reverse-Flash, (official alias "Professor Zoom", commonly referred to as "Zoom") encountered by Barry Allen and Wally West. His role as the Flash's nemesis is continued by the Wally West Flash's greatest enemy, Hunter Zolomon (also known as both the new "Reverse-Flash" and the second "Zoom", sans the "Professor" moniker). In the show this continuity between the two characters is removed.
 * Eobard Thawne, posing as Harrison Wells, appears to be an amalgamation of several comic book characters.
 * In the DC Comics, Garrison Slate is the founder and CEO of Star Labs. He backs superhero teams such as Power Company and The Conglomerate.
 * Also a senior member of Star Labs, a villain only known as "Dr. Wells", appeared in the tie-in DC comic book of the 1990s The Flash TV series titled, Flash TV Special #1 (January, 1991). Interestingly enough, the character was also a wheelchair-bound villain who when wearing a yellow, red, and black suit, had the ability to be in two places at once, similar to how Eobard Thawne (disguised as Harrison Wells) was introduced on the show. He was crippled by an accident at Star Labs as Eobard as Wells pretended to be, and like him, Wells had modified his wheelchair to give him power.
 * Even before that, a villainous character known as Dr. Wells, sporting similar looks, appeared in the 1973-1985 animated series Super Friends episode "Elevator to Nowhere". Like the CW version, Dr. Wells was associated with time travel, likely due to their shared namesake H. G. Wells, and he forced Wonder Woman and the Atom to participate in his time machine experimentation.
