Harrison Wells (Earth-2)

"Sometimes you’re a hardass, you’re a hero. Sometimes... you’re a wizard, Harry."

- Cisco Ramon to Harry

Dr. Harrison "Harry" Wells is the founder of S.T.A.R. Labs on Earth Two and the father of Jesse Wells who was taken by the meta-human criminal Zoom. Harry then traveled to Earth One, joining the team led by Barry Allen to take down Zoom. While he was at one point forced to work as a mole for Zoom, Harry eventually turned on the speedster criminal, and with the help of Barry Allen and Cisco Ramon, freed his daughter from captivity. He continued working with Team Flash as its main scientific mind to defeat Zoom before returning to Earth Two with his daughter and Jay Garrick after Zoom was no more.

After Jesse developed her meta-human powers as a speedster and began establishing herself as vigilante protector in Earth Two, Harry's overly protective and controlling nature caused a strain in their relationship, making Jesse determined to work alone. Feeling he had no other reason to be on Earth Two, Harry decided to rediscover himself on Earth One by rejoining Team Flash.

After his Thinking Cap dramatically decreased his intelligence to the point of barely being able to speak comprehensively, he only managed to retain any intelligence due to Marlize DeVoe. With the majority of his intelligence gone and back in touch with his emotional side, Harry returned to Earth Two.

Early life
When Harrison was 10 years old he solved Earth Two Einstein's riddle.

At some point in his life, Harrison met a woman whom he later fell in love with and married. Harrison initially didn't want children, but his wife later convinced him to change his mind, and they had a daughter together, Jesse Chambers Wells, who Harrison would affectionately call Jesse Quick due to her genius intellect.

Creation of S.T.A.R. Labs
In 1991, Harrison founded S.T.A.R. Labs. At one point, sometime after his particle accelerator exploded and created numbers of meta-humans, he held a press conference to unveil a new series of gadgets and apps to alert the user of a meta-human presence. During the conference he was confronted by Jay Garrick, who wanted to expose his involvement in the meta-humans' creation, but Harry rebuked him by encouraging him to do his job and stop Zoom. Sometime later, Harrison happened upon a tour group of children walking through S.T.A.R. Laboratories and greeted them. He was later confronted by his daughter, who asked him if what the Flash had said was the truth. Although he tried to evade the question, she saw this as confirmation and criticized him for his actions. He replied that he had been trying to unlock the mysteries of the universe, and that if sometimes one doesn't have the key for a lock, he must kick the door open. Some time later, Harrison saw a newsreel about a meta-human attack at Central City College and that a female student had been kidnapped by Zoom. Seeing Jesse's broken cellphone in the wreckage on TV, he was horrified. This later made Harrison believe that Jesse was dead. He would later discover a breach to Earth One after Martin Stein threw a vitals machine of Caitlin's through the breach, which almost hit Harrison. This would give him the idea to go to another world to find help against Zoom.

Hunting Zoom
He found his way through a breach between Earth Two and Earth One, underneath Earth One's S.T.A.R. Labs. Wells lurked around S.T.A.R. Labs for some time, watching the efforts to save Martin Stein. He then proceeded to Mercury Labs where he stole a prototype weapon from the Applied Sciences Division. In doing so, he set off the alarms but managed to evade the guards. He was, however, spotted by Tina McGee, an old friend of Harrison's late Earth One counterpart, who mistook him for the impersonator using his counterpart's appearance.

He later arrived in time to use the gun he stole on King Shark, a meta-human sent by Zoom, and knocked him out as he was attacking The Flash and Patty Spivot. When he walked away, Flash chased after him and demanded to know who the hell he was, and Harry pulled his hood off, revealing his identity to him.

Harrison went to S.T.A.R. Labs where he met Cisco Ramon, Caitlin Snow, and Joe West, who were skeptical of him due to the actions of Eobard Thawne. Joe tried to shoot him when he first walked into the room, only to have Barry catch the bullets. He then explained that his intentions were to help them stop Zoom, who was ordering meta-humans from Earth Two to come to Earth One to kill Barry and then every speedster in the multiverse so he would be the only one.

When another Earth Two meta-human showed up, Dr. Light, later revealed to be the Linda Park of Earth Two, Harry and Jay came face to face for the first time on Earth One. This caused an immediate argument because the two despised each other. Harry accused Jay of cowardice and hiding from Zoom in another universe. Jay disputed this, but Harry dismissed his arguments in favor of the matter at hand, dealing with Dr. Light. Harry wanted to capture her for information, insisting that she was a threat to Barry's life. Jay disagreed, saying that she was a thief rather than a killer and could be reasoned with. Shortly thereafter, they were alerted to a bank robbery in progress, and Barry rushed off as the Flash. Following Jay's advice, Barry, as the Flash, made the attempt to persuade her to stop fighting and let him and his team help her. When he recognized her as Linda Park during their conversation; however, she blinded him and fled. Harry pointed out that if they had followed his advice rather than Jay's, Barry wouldn't have been injured.

When Barry expressed the concern that the Earth One Linda Park might now be in danger, Harry and Jay disagreed once again. Harry wanted them to protect her, Jay wanted them to watch and wait and try to talk to Dr. Light. Despite her earlier attack on the Flash, they continued to follow Jay's plan, which led to Jay and Caitlin being attacked and knocked out while they watched the Central City Picture News office from outside and the death of Linda and Iris' boss, Eric Larkin.

Harry blamed Jay for believing that someone under Zoom's influence could be reasoned with, and he claimed that Jay was the reason Barry doubted himself. When Jay tried to defend himself with the argument that he had hunted Zoom for two years, Harry turned the argument back on him, saying that Jay had been running from Zoom for two years, not hunting him. He compared Barry to Jay, stating that unlike Jay, Barry could beat Zoom because he was not a coward and was willing to rush towards danger and not away from it. At this point, Jay started a physical fight with Harry that Barry had to stop. Shortly thereafter, Barry approached Harry to suggest that he was being hard on Jay, but Harry defended his position, stating that Jay should be learning from Barry instead of the other way around. During this conversation, Barry told him that they had gotten hold of Light's mask in the confrontation at the CCPN office. In order to find Dr. Light, Harry revealed the secret that Cisco was a meta-human with the ability to see alternate timelines and other dimensions.

After Dr. Light was captured, Harry watched as Barry, Caitlin, and Cisco celebrated.

Harry built a gun that would fire a dart that would dampen Zoom's speed once they lured him into the trap. Zoom however knew of the trap and Harry didn't get his chance to take down the demonic speedster. After Zoom brought an unconscious Flash back to S.T.A.R labs after defeating him in battle, Zoom told Harry that he made a mistake trying to use Barry to stop him, which Harry admits his mistake. Zoom is then shot with the dart by Cisco, but manages to still run with his super-speed and escaped, upsetting Wells. Joe slammed Harry against a wall, blaming him for what happened to Barry. Cisco told Harry that he vibed on him earlier as he worked in the office, revealing that his daughter, Jesse, was alive but being held captive by Zoom. Harry told Joe that he overestimated his ability to stop Zoom and thought he could stop Zoom on Earth One and he was doing whatever it takes to keep his daughter safe just as Joe would do anything to keep Barry safe.

Harry decided to leave and go back to Earth Two to fight Zoom due to his mistake of thinking he could recruit The Flash to stop Zoom which lead to Barry getting injured. He is convinced into staying and helping out Team Flash by Caitlin, as they conspire to close all of the breaches except for the one under S.T.A.R. Labs to force Zoom through it the next time he returned to Earth One. Harry helped out the team with the Grodd situation during Barry's recovery by masquerading as Thawne in the Reverse-Flash suit to trick Grodd. While the plan initially went perfect, Grodd was able to see that his "father" was a doppelgänger due to Harry asking Grodd's permission to release Caitlin. Harry was injured but managed to inject Grodd with the tranquilizers. Harry and the team used the Speed cannon to transport Grodd to a gorilla refuge on Earth Two where gorillas who underwent lab experiments were able to roam freely.

With Barry unable to gain more speed, Harry decided to create his Velocity 6 serum, which would temporarily boost a Speed Force user's speed. He and Caitlin remained in Central City while Barry and Cisco took Kendra Saunders to seek shelter with Team Arrow from Vandal Savage. Caitlin later brought in Jay to test Velocity 6, believing that as a former speedster he'd be a perfect test subject. Jay refused to take the "speed drug", stating that the Speed Force could not be lab-made and the drug's effects could not be predicted, and warned Caitlin not to let Barry use the serum. Harry subsequently went out to gather the chemicals needed to synthesize Velocity 6, unaware that Detective Patty Spivot had spotted him. As Harry got Velocity 6 ready, a concerned Caitlin was willing to heed Jay's warning, to which Harry dismissed Jay as a coward. Just as Caitlin left the Cortex, Spivot confronted Harry, accusing him of breaking into Mercury Labs. Harry attempted to approach her but accidentally pointed the syringe gun in his hand towards her, causing Patty to panic and shoot him in the chest. After Joe dismissed Patty, Caitlin had a reluctant Jay take Velocity 6, enabling him to phase his hand through Harry's chest to retrieve the bullet. As Harry recovered, he thanked Jay for saving his life but Jay, other than saying he would never take the drug again, retorted that he could thank him by keeping Velocity 6 away from Barry.

Betraying Team Flash
Zoom made a deal with Harry: Harry would help him steal the Flash's speed and in return he would get his daughter back. After killing The Turtle, and stealing his blood and some brain matter to come up with a speed force reduction serum, Harry designed a drainer which stole Barry Allen's speed every time he tapped into the Speed Force. However, after this nearly cost Iris West her life in a fight with Tar Pit, Harry confesses and is later forgiven by Barry and the members of Team Flash, who tell him that they are going to go to Earth Two together to help him save his daughter.

Return to Earth Two
After Barry closed all the breaches with Harry's breach implosion device, he, Barry and Cisco set off for Earth Two through the S.T.A.R. Labs breach. Upon arrival, Harry became annoyed when his companions took in the sights and panicked upon meeting lab assistant Henry Hewitt, whom the Earth One visitor know as an evil metahuman on their Earth. Subsequently, they learned that Zoom had escalated his reign of terror. Cisco then tried to vibe Zoom, only to discover that his goggles had were non-functional, as the two Earths vibrate on different frequencies, making it impossible for Cisco to vibe. Upon seeing Barry's doppelganger on TV, he replaced him, hoping to get CCPD's information on Zoom in hopes of finding him. Unfortunately, Barry forgot Jay's advice not to get sucked in emotionally and became involved with Iris and Joe's doppelgängers, before Joe was incidentally killed in a confrontation with Caitlin and Ronnie's doppelgängers, Killer Frost and Deathstorm. Harry scolded Barry for forgetting his objective, stating that the inhabitants of Earth Two are not the people he knows but Barry rejected his words.

Subsequently, Barry and Cisco try to help Iris Two track down Killer Frost and Deathstorm, but something went awry and Zoom captured Barry and started tearing Central City apart looking for Harry. After ordering S.T.A.R. Labs evacuated, Harry nearly pulled his gun on Cisco, who revealed that Zoom had killed his doppelgänger Reverb and Deathstorm, but spared him and Killer Frost and took Barry; Harry suspected that Zoom left Cisco alive for a reason. They then remembered they left Barry Two locked up and free him, before Zoom attacked S.T.A.R. Labs. The trio took shelter in Harry's time vault, hiding behind a fake wall when Zoom entered. Afterwards, they explained everything to Barry Two and later Iris Two. Knowing that Barry and Jesse would mostly likely be in Zoom's lair, the group decide to seek out Killer Frost, as only Zoom's henchmen would know. After a brief fight, Cisco is able to convince Killer Frost to take them to Zoom's lair, Ascension Cliffs, which Harry noted is only accessible for speedsters. They get inside with Killer Frost producing an ice staircase. Though Harry is able to free Jesse, Barry's cell was lined with carbine, which he couldn't phase through because of the frequency differential. Thankfully, Barry Two is able to coax his doppelgänger into getting the courage to phase through. Unfortunately, Zoom then arrived, having been summoned by Killer Frost. Zoom declared he would everyone but Barry and Harry, starting with Jesse. But then Killer Frost had a change of heart and held off Zoom long enough for everyone to escape. Once back at S.T.A.R. Labs, Harry grimly tells Jesse that they had to leave Earth Two forever. As the meta detectors go off, indicating Zoom was near, Barry got Cisco and Jesse through the breach, but when he got back, Zoom had Harry in his clutches, declaring he needs the two of them to get his speed. Unseen, Harry drew a speed dampening dart and asks Barry to give his love to Jesse, before stabbing Zoom with the dart, stunning him long enough for Harry and Barry to get back to Earth One. Jay then used the breach implosion device to close the breach, but not before Zoom reached through, phasing his hand through Jay's chest and dragging him back through. This broke Caitlin's heart and Harry had to grimly tell Barry that there's no way to reopen the breach. Later, he advises Barry and Cisco not to tell anyone of their experiences on Earth Two, as it might affect the people of Earth One, as well as the fact that those lives weren't theirs.

Stuck on Earth One
With their path home permanently cut off, Harry and Jesse settle in at Earth One S.T.A.R. Labs. Within a few weeks following Jay's death, the team was visited by John Diggle and Lyla Michaels, who revealed that King Shark had not been killed by Harry, but had in fact been taken in by A.R.G.U.S. to find a way to weaponize metahumans. King Shark had recently escaped A.R.G.U.S. custody and was heading back to Central City to fulfill his original objective to kill Barry. Harry was then asked if he had any information on King Shark, to which he identified him as Shay Lamden and that finding him the first time was pure luck after he first arrived on Earth One.

Harry later began working on an algorithm to track King Shark. Jesse offered her help, though it took a bit of convincing. Later on, Harry stood with Jesse and Cisco at the Cortex while Barry and A.R.G.U.S. set a trap for King Shark. When the trap failed, Barry challenged the man shark to a race at sea, before creating a whirlpool of electricity, trapping King Shark before stunning him with the lightning toss.

After King Shark was returned to A.R.G.U.S., Barry assembled the whole team at the Cortex, placing Jay's helmet in a glass case and vows to get faster to beat Zoom.

Jesse runs away
Harry later becomes part of an experiment to increase Barry's speed by having him run across a gorge; the attempt failed and Barry would've fallen to his death had not Cisco's drones rescued him.

Deciding to take a break, Jesse pleads with her father to let her go out clubbing with the team. He consented, but not before giving her his meta-detector. This later proved to be a mistake, as Jesse accidentally discovered the recording where he confesses to murdering Turtle.

After the appearance of another speedster who robbed the same club where Jesse was, incidentally framing the Flash, Harry and Caitlin are forced to reveal the existence of the Velocity serums to Barry and warn him of the fatal side effects. Harry later caught Barry stealing the one vial of Velocity 9 and talks him out of using it on himself, encouraging him to be more like Jay.

Subsequently, the new speedster, Trajectory, whom Caitlin recognized as her Mercury Labs colleague, Eliza Harmon, arrived at S.T.A.R. Labs, locking Barry in the Pipeline and taking Jesse hostage to force Caitlin and Harry to make more Velocity 9. Once they had done so, Eliza injected Jesse with the serum to test if they had put a sedative in it, causing Jesse to get a seizure. Eliza then runs off, giving Cisco an opening to release Barry, who chases after her but loses her.

Harry later sat by his daughter's side as she recovered and had to endure her anger at how he gambled with her life. Later on, Harry discovers a farewell letter from Jesse, who had left to explore a whole new world.

After Barry and Eliza's confrontation resulted in the latter disintegrating from an overdose of Velocity 9, Barry tells the team that he witnessed Eliza's lightning turn blue before she died. Harry then realized that Zoom is dying from Velocity 9 and needs Barry's speed to cure himself. Barry notes that Jay had the same disease. Harry then turned to Cisco, knowing his vibes could verify the truth. Cisco then confessed that he had been vibing Zoom since they closed the last breach, always in proximity to Jay's helmet. Upon vibing on it, Cisco sadly confirms that Jay is Zoom.

Harry later searched for Jesse for weeks to no avail. When he returned to S.T.A.R. Labs, he overhears Barry discussing his plan to go back in time one year to learn from Eobard Thawne how to get faster to defeat Zoom. Harry deplored his plan, reminding that Eobard had fifteen years to study Barry and would likely deduce what's going on, as well as the fact that he'd risk altering the timeline. Nonetheless, Barry went through with his plan.

Trapping Zoom
Barry's successful time travel trip gave him information on tachyon enhancement, enabling the team to construct a tachyon enhancer. After a successful test run, Harry tells the team that there's no way to return to Earth Two. However, Barry suggests that Cisco could open a breach, given that he has the same powers as his doppelganger Reverb.

Harry later visited Joe to ask him to try and convince Barry not to fight Zoom, but Joe stated that Barry can't be stopped when he's put his mind to something and that Harry should instead help him. Harry did just that by modifying Cisco's goggles to assist him in manipulating multi-dimensional energies. He joins Barry and Cisco at an abandoned hospital, which was a hotspot for multiversal energies. Cisco nearly opened a new breach, only to hesitate.

Later, Harry overhears Caitlin telling Barry about "Jay's" Earth One doppelganger, Hunter Zolomon, expressing familiarity, revealing that Earth Two Hunter is a convicted serial killer, "Jay's" true identity. He explained Hunter's backstory, how his father killed his mother, resulting in Hunter being sent into the foster care system. When Harry's particle accelerator exploded, Hunter was undergoing electro-shock therapy at the time when the dark matter hit, creating Zoom. Realizing that Hunter thinks his past is a secret, Barry decided to use this information to his advantage. He prepares himself and Joe with pulse rifles.

The trap is almost effective, but Hunter removes the foot dampener and kidnaps Wally so Barry gives Hunter his speed. Harry tells Hunter that he would erase Hunter's smug smile before being forced to calibrate the devices he used to steal some of Barry's speed. When Barry is in a treadmill, Harry robs his speed and takes the devices to get the speed. Wally is released, but Hunter almost kills Barry and manages to kidnap Caitlin.

When Barry and his daughter came from 2018 to collect Harry's device to stop Cicada, Harry found Barry and scared him by aiming him with his gun. Angry for Zoom winning, Harry almost destroyed his device, but Barry managed to calm him down by telling Harry how he could save his daughter by locating her due to different frequency Earth-2 people vibrate.

Finding his daughter and having a realization
He blamed Barry for the aftermath of Zoom's healing. Iris and Joe tried to make him stop saying that as giving Barry's speed to Zoom was a decision taken by the team. Harry finally knew where is his daughter since Earth-2 people vibrate at a different frequency. When Harry arrived to the place in which Jesse has stayed he finds her flatmate, who mocks Harry's gun before knowing he wants to meet Jesse. However, Jesse didn't want to go with him, blamed him for all what happened and mentioned his murder of Russell Glosson and his general immorality when it comes to protect her.

In his road to S.T.A.R. Labs, his car is stopped by Griffin Grey, a superstrong metahuman who also kidnapped him in Ace Chemicals. After awakening, Harry learned Griffin's name and situation. Griffin was a metahuman from Thawne's Particle Accelerator and wrongly thought Harry was the "Harrison Wells" who caused his situation. Griffin's super-strength had a deadly effect on him every time he used it, that is, making him age rapidly. The reason Griffin kidnapped Harry is to have him make a cure. While Team Flash with Jesse's help learnt about the situation and tried to rescue him, Harry sought to make a cure to no avail. Griffin told Harry that he (Griffin) had a girlfriend he loved and that he wanted to marry her and have children with her, but his transformation as a metahuman ruined that possibility. Griffin scolded Harry and accuses him of ruining lives with the Particle Accelerator while still confusing him with "Harrison Wells".

Harry tried to fool Griffin by diluting the compound repeatedly, but Griffin was not fooled, for he knew chemistry. As a retaliation, Griffin threw Harry to the floor. Team Flash found Griffin and tricked him to use his powers to make him age rapidly and die, although Barry wanted him to stop. When Harry was rescued; Jesse opened his cuffs and hugged him. He and Jesse went to their room in S.T.A.R. Labs, where they discussed. Harry tells Jesse that his protective attitude comes from fear of losing her after he lost his wife. Jesse asked his father to stop being so overprotective of her and Harry promises her to be a better father if she doesn't escape again. They hug each other and Harry calls her "Jesse Quick".

Later, Harry commented with Barry that Griffin was right about what he said despite mistaking Harry with the fake Wells and promised Barry to restore his speed as a means to atone for what he did.

Restoring Barry's powers
Barry, however, was reluctant to recreate the particle accelerator explosion, and was instead content with projecting a hologram of the Flash to do crimefighting. Harry pointed out the flaws with his hologram in terms of actual combat and insisted that he could contain the accelerator explosion to S.T.A.R. Labs.

After Cisco escaped a near-death encounter with his brother Dante's doppelganger, Rupture, Harry explained to the team how Zoom created his own metahuman army on Earth Two and killed those who would not submit, making another appeal to restore Barry's powers.

Ultimately, Barry conceded to Harry's plan when Zoom murdered a number of officers, along with Rupture for failing him. After confining Wally and Jesse in the Time Vault, Harry recreated the circumstances of how Barry got his powers, with Cisco on the roof using the Wizard's Wand to summon a lightning bolt. However, the resulting accelerator explosion seemingly vaporized Barry. Zoom appeared soon after, mocking Team Flash for killing their hero before running off.

Henry was disgusted with him, but still assisted his daughter. Barry was released from the Speed Force by Iris and could defeat Tony Woodward easily.

Defeating Zoom
After Black Siren destroyed Mercury Labs, Barry rescued Tina McGee and she revealed him that she'd known his identity all along. She was sent to S.T.A.R. Labs, where she asked if Harrison Wells had to do with the assault, to which Harry answers no, but confessing he did the first time. He and the team then filled her in on everything that'd happened.

Jesse noted that Harry genuinely cared about Team Flash.

After a dinner, Zoom murdered Henry, which broke Barry. Most of the other teammates, including Harry, was among the ones who put him in the pipeline to prevent him from killing Hunter Zolomon. Wally disagreed and released him. Barry defeated Zoom by sending a time remnant of himself to sacrifice his life to stop the magnetar and to attract the time wraiths. After that, Cisco and Harry unmasked the prisoner, who was Jay Garrick, the Earth Three counterpart of Henry Allen.

Before Harry, Jesse and Jay went to Earth Two, they bade farewell to their Earth-1 friends. Harry thanked Barry for making him a better person.

Post-Flashpoint
On Earth Two, Harry explained to Jay what happened to Barry and why he was shocked of seeing him. Jay was afraid that Barry would take a bad decision, so he decided to keep an eye on him. Jay's fears were proven correct, since Barry created Flashpoint and was trying to undo everything to mend the present issues with his partners.

Harry and Jesse were unaffected by Flashpoint, since they were on another Earth when that timeline was created. They came because Harry wanted the team to dissuade a Speed Force-powered Jesse from doing heroics. Harry finally desisted from that and gifted her Trajectory's suit.

To find a substitute for him, Harry sent his alternate selves on the multiverse an equation. When his Earth-19 counterpart appeared, Harry was very suspicious of him. After said counterpart, named H.R. Wells, arrived to Earth One, Harry returned to his Earth alongside Jesse.

Harry was eventually kidnapped by Grodd. Jesse went to warn Team Flash, who helped her. Then they went to Earth Two, but they were trapped.

Harry left Jesse on Earth One and went back to Earth Two, but asked Wally to care after her.

Joe, Iris and Wally went to Earth Two to keep Iris safe from Savitar (a future evil clone of Barry Allen). After H. R. accidentally revealed Savitar that Iris was with Harry Wells, Savitar went after them. After that, Savitar apparently killed Iris, but H.R. was the real dead there, since he used the transmogrification device to switch likeness and place with Iris. While Harry despised H.R., he was saddened to learn that and appreciated his efforts as a hero. He persuaded Tracy Brand (H.R.'s girlfriend) to help Barry and Iris to create a means so Savitar did not get erased.

Finally Savitar disappeared and Barry was taken into the Speed Force, so Harry decided to remain with Team Flash for a while.

Return to Team Flash
After contributing to Cisco's plan to rescue Barry from the Speed Force, Harry returned to his Earth. There, he and Jesse formed a team similar to Team Flash. However, Harry Wells was so demanding and bossy that all of the other members, including Jesse, kicked him off the team. It may have also had to do with Jesse's attempt to have him accept the death of his wife.

When he wanted to go to Earth One, Jesse asked him to send Wally a break-up cube. He was first accused of cruel because he already tried to sabotage their relationship. However, Wally eventually discovered that Harry was telling the truth when he went to verify with Jesse.

Becky Sharpe ("Hazard") was causing bad luck in Central City that the particle accelerator turned on; while Cisco and Harry tried to stop, Harry had the idea to let it go so the bad luck would be negated. Harry was right, but he did not deduced it logically. After Barry as The Flash arrested Becky, Harry clunkily apologized to Cisco for his rude behavior and Cisco received him into the team.

Personality
"You know, our Dr. Wells may have been evil, but you're just a dick."

- Cisco Ramon

As noted by his daughter, Harry was once very similar in nature to his Earth One counterpart, being very kind and cheerful with an upbeat nature. However, after losing his wife, Harry became cynical. Almost similar to Eobard Thawne, Harry carries himself in a very sardonic, egotistical manner. However, unlike Thawne, he is very blunt and inconsiderate. For example, he straight up told Cisco Ramon that they don't have to like each other in response to Cisco's initial wariness of Harry. He laughed in amusement when told of Cisco's murder by Thawne in an alternate timeline and he bluntly told the man known to him as Jay Garrick that the Flash of Earth Two wasn't hunting or even fighting Zoom but was hunted by Zoom instead, even though he never knew the truth of the matter. Wells lacked a certain point of sarcasm which seemed strange to most Team Flash's members.

Harry also seems to be rather unrepentant about his actions; despite knowing that his actions are responsible for the creation of the meta-humans, he did not divulge this information to the public, and tried to profit from the subsequent scare. He felt justified in this by the fact that his work was unraveling the mysteries of the universe. Only after his daughter was kidnapped by Zoom did he begin to get involved in the quest to stop the evil speedster. Harry’s experiences with Team Flash seemed to have awoken the conscience he ignored in the past in favour of progress as he now questions what good he has done when confronted with his character flaws that ultimately drove away his daughter, only for his friends to remind him that in spite of all his rough edges he is a hero to his core.

However, Harry's harsh attitude, appears to be derived from a desperation to save his daughter, showing that he does indeed actually care quite a bit for others that are close to him. His devotion to his daughter makes him emotionally blind, resulting in him endangering Barry Allen's life in his desperate attempt to get his daughter back but even so, he felt guilty for getting Barry injured. He is even willing to kill bystanders he deems necessary for the sake of saving his daughter, as seen from him killing Russell Glosson to harness power against Zoom, much like Eobard similarly willing to murder anyone seen an obstacle of returning to his own time. Harry's problem is that he is so heartbroken after losing his wife that he has become more bitter and very fearful of engaging to people to then lose them.

Despite his reclusive nature, he does care about those around him. He felt guilty for getting Barry injured when he first confronted Zoom, almost leaving to go back to his earth to prevent any more of Team Flash from being hurt. He was also willing to risk his life to save Caitlin from Grodd dressing up as the Reverse-Flash to try and trick Grodd into releasing her.

Since the start of his collaboration with Team Flash, Harry has become noticeably more humble and open with others, like his Earth One counterpart. While still desperate to save his daughter, he is willing to risk his own life to help and protect others, such as when he was shown trying to collect all the bombs (albeit in a manner that made him look like the Grinch) distributed by Trickster and Weather Wizard as Christmas gifts to the children of Central City as insurance that the Flash would not fight back. He advised Barry to not tell Patty Spivot of being the Flash of Earth One, as doing so would undoubtedly make Patty a prime target for Zoom, just like his daughter was.

He also achieved a reconciliation with Jay of sorts after the latter saved his life. His greatest relationship improvement has been with Cisco, where initially they both could barely stand to be in the same room. However, over the course of their war with Zoom, Cisco and Harry has been shown to build a rapport, work together on difficult tasks, even engage in friendly banter, such as the duo simultaneously calling Barry's new plan to deal with the zombie Girder, Plan H, after Cisco had mentioned to Wells that Plans A through G had failed minutes earlier. Harry has single-handedly helped Cisco hone and discover more about Cisco's vibe abilities than anyone else on the team. The duo still manages to annoy one another, such as Cisco by slurping his coffee as loudly as possible despite Harry asking him not to, and Harry tossing Cisco nitrous grenades, which had the potential to bring the entire S.T.A.R. Labs down.

Sometimes, Harry is even shown to have a rather dry sense of humor. Some notable examples include him instructing Joe West, a seasoned police officer, to fire a specialized gun simply by pointing and shooting, telling Earth Two Barry to go easy on Earth One Barry, after Earth Two Barry finds out his Earth One counterpart kissed his wife, and pretending to Joe that he had little idea of what Team Flash's latest invention to get rid of all Earth Two meta-humans actually did, in order to Joe feel better about his technological ineptitude, who was disappointed that he had been had once Harry revealed he knew exactly what it did. Like Cisco, he is also an avid fan of movies. He is shown making a "Godfather" reference by asking why Central City was not swimming with the fishes when inquiring as to how Weather Wizard's original attack had not succeeded. When Cisco was surprised that Earth Two has the Godfather, he replies "Every Earth has the Godfather, Vito". The Duo also thought that their plan to rescue Jesse was similar to the Princess Leia rescue plan from Star Wars, except without a trash compactor. Right before leaving for Earth Two, Cisco was complaining about how he had no split. Harry mistook this as Cisco making a Jaws reference.

Harry is also shown taking unconventional methods and was willing to risk his own life to obtain results since the beginning of his collaboration, such as when he dawned Eobard's suit in order to go rescue Caitlin Snow from Grodd, which led to him being attacked by both Grodd and Barry, and later again to help Cisco better hone the latter's abilities. This is in stark contrast with the Harrison Wells who kept his particle accelerator mishap a secret and instead opted to create meta-human detectors from the catastrophe the mishap led to. Though, his willingness to down anything he needs to, has not always been used for the betterment of the team, as he is also shown stealing Barry's power in an effort to get his daughter back (albeit later confessing to Barry and his team). Harry was very guilt-ridden for this betrayal, to the point that he finally admitted it openly. Wanting to correct his mistake, he instructed Barry to close all bridges between Earths One and Two so Zoom can't return and face the consequences of his actions. He is also shown asking others for help, such as when he asked Joe to plead to Barry to not re-open the breaches to Earth Two, something he would have never done before.

Harry also appeared prejudiced against French people, disregarding his Francophone doppelganger from another universe, saying that he "can't trust a mime", despite French Wells's solving of the equation.

Despite his intelligent and egotistical nature, Harry has displayed a great dislike towards doppelgängers of himself. His interactions initially with H.R. were of a latent hostility about him lacking the genius Harry had and outwardly called him a “moron”. It’s implied this dislike was only a result of H.R. being the preferred Wells on Team Flash compared to Harry. However after H.R.’s sacrifice to save Iris West from Savitar leading to his own death, Harry showed a high level of respect to his doppelgänger's bravery and even attended the latter's funeral. Also, Harry found the Council of Wells insufferable at first due to sharing many of the negative traits that he shared despite being the founder of said council, though with advise from Cisco he learned to consider them his friends eventually.

With his interactions with the Thinker, Harry has shown to an inferiority complex when his intelligence is beaten. When he can't find a solution, he feels useless as he takes pride in the fact that he could find an answer to anything. But when he can't out-think DeVoe, he becomes closed off and irritable to everyone around him. He has shown that he is even to willingly put himself at risk to try and boost his intelligence to try and match his intellectual rival. After the creation of his Thinking Cap, Joe compared his obsession with using the device to Francine West's drug addiction.

When he finally had Gideon add dark matter to his thinking cap, it made him gradually lose his intelligence. However, with help from the Council of Harrisons, he learned to be more empathetic, which allowed him to predict that Marlize DeVoe abandoned her husband and that she would be the key to stop him. After DeVoe was defeated Marlize left a program to restore Harry's intelligence. The program gave him a human mind, his memories of his loved ones and knowledge about popular culture, but failed to restore his scientific knowledge. Harry thought of this as a blessing, since for him he now had a balance of mind and heart.

Abilities

 * Agility: Harry proven himself to be very nimble and agile at times, such as when he did a dolphin-dive and shot a blast from his energy rifle at Zoom.
 * Keen intellect/Leader: Harry is very insightful to everyone’s plans. He is also a skilled businessman, as he managed to run S.T.A.R. Labs very successfully for over two decades. Harry is skilled in acting, having managed to fool the entirety of Earth Two in regards to where the meta-humans came from. His impression of Eobard Thawne was accurate enough for Cisco to appear nervous and to fool Grodd. Despite losing the majority of his mental parameters, Harry's brain damage came with a trade-off advantage of being able understand others emotions and use them to predict their behavior as he accurately inferred Marlize DeVoe abandoned her husband.
 * Skilled combatant: Harry has some experience in unarmed combat, as he was able to go head-on with Hunter Zolomon, yet the exact level of his fighting skills is unknown, as the fight was broken up by Barry.
 * Expert marksman: Harry has proven himself to be very proficient with his Mercury Labs energy rifle.

Former abilities

 * Genius-level intellect: Harry was an extremely hyper-intelligent, excelling in several fields of science and having 7 PhD's. His intelligence was noted to even exceed Eobard Thawne's, a well-regarded genius even by the late 22nd century's standards. Very methodical and calculating, he was able effectively recreate the dark matter explosion that gave birth to the first generation of Earth One meta-humans. He was master engineer as he was able to create a watch to detect meta-humans, a particle accelerator and a modified version of the Thinking Cap. However, after overloading the Thinking Cap's capacities with an overdose of dark matter, Harry's mind was permantely damaged, unable to apply his highest- mental performances anymore.

Equipment

 * Mercury Labs energy rifle: Shortly after coming to Earth One, Harry stole a pulse rifle from Mercury Labs. It can fire a beam of energy which is very powerful, capable of blasting holes through walls and hurting durable enemies like King Shark.
 * Thinking Cap: In order to help Team Flash defeat Clifford DeVoe/The Thinker, Harry created a modified version of the Thinking Cap that DeVoe used. It increased Harry's intelligence to the point he was able figure out the names of the last two remaining bus meta-humans, something the entirety of Team Flash was unable to do.
 * Speedster Protection Nanite Infusion: After his battle with Savitar, Harry injected a nanobot infusion into his body. This infusion gives Harry immunity to a Speedster's attempt to vibrate their hand into his body.

Trivia

 * Harry had repeatedly been mistaken for the counterpart of Eobard Thawne by members of Team Flash when he is actually the Earth Two counterpart of Harrison Wells from Earth One, as he had to repeatedly correct them. But the team still continues to differentiate Harry by referring to Eobard as the "other Wells".
 * Since Harry has out in public since returning to Team Flash, it's possible that he either was given or gained access to H.R.'s identity concealment tech.
 * However, given that Harry wears a cap and sunglasses when out in public on Earth One, it's unlikely.
 * Cisco Ramon refers to Harry as the "dickish Wells" due to his poor people skills.
 * Harry's blood type is PZ Negative, something that doesn't exist on Earth One.
 * Harry brushes his teeth front to back.
 * He has 7 PhDs.
 * It's implied that Harry cannot speak Latin, unlike Eobard.
 * Apparently, Harrison Wells doesn't exist on Supergirl's Earth. However as shown by Jay Garrick being Henry Allen's counterpart from Earth Three, same versions of people do not necessarily have the same name.
 * Harry shares similarities with Martin Stein:
 * Both have provided central technical support to Team Flash in Eobard's place.
 * Both have had encounters with Eobard involving identity theft.
 * Both are incredibly challenging fathers to their respective daughters.
 * He is the only version of Harrison Wells who has appeared on all four Arrowverse shows.
 * He is also the only version of Harrison Wells who has met all four main antagonists
 * Harry is the seventh character in the Arrowverse to have his civilian name in an episode title, after Sara Lance, Felicity Smoak, Harrison Wells, Oliver Queen, Alex Danvers and Zari Tomaz.
 * He is also the first character to have two episodes named after him.
 * Harry calls Ralph Dibny "Disney" due to the latter's cartoonish personality.

Behind the scenes

 * Harry's bloodtype PZ Negative may be a reference to his impersonator Eobard Thawne (in DC Comics) having the title of Professor Zoom and is the wielder of Negative Speed Force.
 * Even though Harrison Wells does not originate from the DC comics, as he is an original character specifically created for the show, another brief character, 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).
 * Even before that, a villainous character known as Dr. Wells, sporting similar looks, appeared in the 1973-1985 animated series Super Friends.

List of things he created, modified, contributed

 * 1) Particle accelerator: Like Eobard Thawne (masquerading as Harrison Wells of Earth One), Harry Wells of Earth Two created a Particle accelerator. Unlike Earth One "counterpart", he didn't create an explosion, but rather let the dark matter outburst flow underneath Central City, thus creating metahumans.
 * 2) Meta-human detector app: This app was created by Harry to instantly detect Meta-human, know their presence and to find them.
 * 3) Speed dampening serum: Wells was working on a serum on Earth Two to stop Zoom. He finalized it in Earth One. He tried to use it to stop Zoom but ended up using it on Barry Allen.
 * 4) Velocity 6: This serum was created in order to help increase Barry and Hunter Zolomon's speed temporarily in the fight against Zoom. It is used by Hunter reluctantly years later in order to phase through Harry's chest and remove a bullet after he was shot by Patty Spivot.
 * 5) Vibe Glasses: Harry also modified the glasses to help control Cisco Ramon's powers, as well as increasing them. He did this by calibrating them in a different frequency. By doing this Cisco's powers have increased to the point where Cisco can now open breaches to other Earths.
 * 6) Tachyon unit: Harry created a variant of the tachyon prototype for Barry to use in order to increase his speed.
 * 7) Speed Force transmitter: Initially created to steal Barry Allen's speed for Hunter Zolomon, Harry later converted this into a "miniature tachyon device" to increase Barry's speed.
 * 8) Time Vault: Like Eobard Thawne, Harry created a Time Vault, though only using it as a hidden bunker in the likelihood that Zoom were to be hunting him. It is well stocked with a variety of weaponry and food supplies.
 * 9) Thinking Cap: Like DeVoe, Harry created a thinking cap in order to help Team Flash figure out the identities of the last two bus metas.
 * 10) Sonic Scepter: An item to launch sonic waves strong enough. Since they do not depend on electrical technology, Kilg%re's powers would not work on it. It was built as a means to combat Clifford DeVoe, since he was weak to sonic waves and he'd absorbed Ramsey Deacon's powers.

List of individuals he nicknamed

 * Sam Scudder as "Mirror Master"
 * Neil Borman as "Fallout" (co-named with Cisco and Caitlin)
