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-2, the husband of a late unnamed woman, and the father of Jesse Wells. After Jesse was kidnapped by the meta-human criminal Zoom, Harry traveled to Earth-1, joining Team Flash and helping 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-2 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-2, 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-2, Harry decided to rediscover himself on Earth-1 by rejoining Team Flash.

After his excessive use of the 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-2.

In 2019, Harry was presumably vaporized and killed, along with the rest of Earth-2's population, when a wave of antimatter hit and subsequently destroyed the universe.

Early life
When Harrison Wells was 10 years old, he solved Earth-2 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, whom 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 the meta-human awareness app in a new series of next gen gadgets, designed 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. Labs and greeted them. After the conference, confronted by his daughter, she asked him if what the Flash had said was the truth. Although he tried to evade the question, Jesse saw this as confirmation and criticized him for his actions. Harrison 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.

One day, after Harrison watched the news report about Robert Queen being the Starling City vigilante, "The Hood", he saw a newsreel about a meta-human attack at Central City College and that a female student had been kidnapped by Zoom. Upon seeing Jesse's broken cellphone in the wreckage on TV, he was horrified, initially believing that Jesse was dead. Not knowing the fate of his daughter, Harrison dedicated himself to find stop Zoom and find out what happened to his daughter.

After The Flash vanished, Harrison believed that Zoom had killed him in their last duel during the Singularity. Harrison would later discover a breach to Earth-1 after Martin Stein threw a vitals machine through an interdimensional breach, which almost hit him. 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-2 and Earth-1, underneath Earth-1'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 break into 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-1 counterpart, who mistook him for the impersonator using his counterpart's appearance.

Harry 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-2 to come to Earth-1 to kill Barry and then every speedster in the multiverse so he would be the only one.

When another Earth-2 meta-human showed up, Dr. Light, later revealed to be the Linda Park of Earth-2, Harry and Jay came face to face for the first time on Earth-1. 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 his former flair Linda Park during their conversation, however, she blinded him and fled. Harry angrily 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-1 Linda Park might now be in danger, Harry and Jay disagreed once again. Harry wanted them to protect her while 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 before pinning their entire situation on him. 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 Zoom had in fact been hunting him, and Jay had not been doing anything but running from the demonic speedster. 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. Fed up with Harry's remarks, Jay engaged with Harry in a physical fight 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. Barry mentioned that prior to learning he was the Reverse-Flash, Barry looked up to Earth-1 "Wells" as a role model and mentor, prompting Harry to remind Barry that he wasn't his Earth-1 counterpart and Barry needed to take his advice in order to take Zoom down. 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 explained that all the team had to do was give Light's mask to Cisco and exposed his status as a metahuman with the ability to vibe the location of anyone just by using an object that belonged to them.

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 a horrified Harry admitted. Zoom was then shot with the dart by Cisco, but managed to still run with his super-speed and escape, 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-1 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-2 to fight Zoom due to his mistake of thinking he could recruit The Flash to stop Zoom which led 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-1. 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-2 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-2 together to help him save his daughter.

Return to Earth-2
After Barry closed all the breaches with Harry's breach implosion device, he, Barry and Cisco set off for Earth-2 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-1 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 been 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-2 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 most 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-2 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-1. 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-2, as it might affect the people of Earth-1, as well as the fact that those lives weren't theirs.

Stuck on Earth-1
With their path home permanently cut off, Harry and Jesse settle in at Earth-1 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-1.

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-2. However, Barry suggests that Cisco could open a breach, given that he has the same powers as his doppelgänger 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-1 doppelgänger, Hunter Zolomon, expressing familiarity, revealing that Earth-2 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 was nearly effective, but Hunter removed the foot dampener and kidnapped Wally to force Barry to give up his speed to see Wally alive. Harry told 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. As Barry ran on the treadmill, his speed was gradually transferred into Harry's device which Hunter then injected into himself, obtaining Barry's speed. Wally was subsequently released, but Hunter used the opportunity to try and kill a weakened Barry before he was stopped by Caitlin. Zoom then kidnapped Caitlin and took her to his base on Earth-2 (although Team Flash did not know where she was until much later), leaving Harry and the other members of Team Flash in shock.

When a version of Barry from 2018 and Nora West-Allen traveled back in time to 2016 in order to collect Harry's device to stop Cicada, Harry found 2018 Barry and alarmed him by aiming at him with his gun, before asking him how he changed so quickly out of his suit (mistaking 2018 Barry for his past self, who had just lost his speed to Zoom). Still reeling over Zoom's victory and success in stealing 2016 Barry's speed, Harry found the device and almost destroyed it in rage, but Barry managed to calm him down by telling Harry how he could save his daughter by locating her due to the different frequency at which individuals from Earth-2 vibrate. A frustrated Harry then told 2018 Barry to work to find Caitlin, still unaware that he was from the future.

Finding his daughter and having a realization
Harry blamed Barry for the loss of Barry's speed and Zoom gaining the upper hand. Iris and Joe tried to make him stop saying that as giving Barry's speed to Zoom was a decision taken by the team, although Harry disagreed while implying that he, for one, was not fully on-board with Barry's decision. Harry finally figured out the whereabouts of his daughter since Earth-2 people vibrated at a different frequency, and he used cellular dead zones to track her down. When Harry arrived at the place in which Jesse stayed, he found her flatmate, who mocked Harry's gun before Harry asked her for Jesse. However, Jesse didn't want to go with him, blaming him for what happened and saying that his murder of Russell Glosson was a line that Harry crossed when trying to protect her, and demanded that Harry leave.

A visibly saddened Harry drove back to S.T.A.R. Labs and in his distraction, crashed into Griffin Grey, who used his super-strength to absorb the blow and direct it back at Harry's van, leaving Grey unharmed but harming Harry. Having stood directly in front of the van for a reason, Grey then kidnapped the unconscious Harry and took him to the Central City Amusement Park. After awakening, Harry learned Griffin's name and situation. Griffin was a meta-human created from Thawne's particle accelerator and wrongly thought Harry was the "Harrison Wells" who caused his situation. Griffin claimed that his powers were a curse and showed Harry his super-strength, but Harry said that Griffin's powers were impressive and Grey had no reason to hate it as much as he did. However, Grey then revealed the side effect of his powers: every time he used it, he would age rapidly and uncontrollably, and desperately needed a cure before he died of old age, kidnapping Harry so he could create said cure. While Team Flash, with Jesse's help, learned about the situation and tried to rescue him, Harry sought to make a cure to no avail. Griffin told Harry of his plans to marry and have a life with his girlfriend, all of which were ruined when he became a metahuman. Griffin scolded Harry and accused him of ruining lives with the particle accelerator, while still confusing him with Earth-1's "Harrison Wells".

Harry tried to fool Griffin by diluting the compound repeatedly, but Griffin saw through the act, having developed an apt knowledge of chemistry. Once Harry said that there was no fixing him, an enraged Griffin threw him to the ground. 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 told Jesse that his protective attitude came from the fear of losing her, the only other person Harry loved, after the death of Harry's wife. Jesse asked his father to stop being so overprotective of her to the point that he murdered, and Harry promised to be a father she could be proud of so long as Jesse didn't try to run away again. They hugged each other and Harry called her "Jesse Quick".

Later, Harry commented with Barry that, despite Griffin confusing Harry with Earth-1's "Harrison Wells" and speaking about him and not Harry, he couldn't help but feel that he had not fully repented for his own actions on Earth-2 and the fallout of his own particle accelerator explosion. As a result, when Barry asked how Team Flash would get his speed back, Harry said that he intended to right his wrongs and proposed the idea of recreating the particle accelerator explosion on Earth-1.

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 doppelgänger, Rupture, Harry explained to the team how Zoom created his own meta-human army on Earth-2 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 dinner, Zoom murdered Henry, which broke Barry. Most of the other teammates, including Harry, were 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-3 counterpart of Henry Allen.

Before Harry, Jesse and Jay went to Earth-2, they bade farewell to their Earth-1 friends. Harry thanked Barry for making him a better person.

Post-Flashpoint
On Earth-2, 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 in Earth-1, 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-2, but they were trapped.

Harry left Jesse on Earth-1 and went back to Earth-2, but asked Wally to take care after her.

Joe, Iris, and Wally went to Earth-2 to keep Iris safe from Savitar (a future evil time remnant 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-1, Jesse asked him to send Wally a break-up cube. He was first accused of lying because he had already tried to sabotage their relationship prior. 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 deduce it logically. After the Flash arrested Becky, Harry clunkily apologized to Cisco for his rude behavior and Cisco received him into the team.

Discovering Clifford DeVoe
After Barry revealed that a possible enemy of his would be named "DeVoe" as told to him by Savitar and Abra Kadabra, Harry and Cisco attempted to determine who DeVoe was but found it nearly impossible as they only had a surname to go off of. As a result, Harry assembled the Council of Wells, a group comprised of the smartest Harrison Wells doppelgängers in the multiverse, to help him with the task, and they were able to successfully determine DeVoe's identity as Clifford DeVoe and his location.

Harry subsequently provided backup with his gun as Barry and Joe went to confront Clifford at his home, but stood down when he found that Clifford was just a regular man in a wheelchair (although initially unknown to him and the rest of Team Flash, Clifford was just feigning innocence and he truly was the enemy Savitar described). However, once Clifford revealed his true colors during a confrontation with Barry, Harry learned of Clifford's real intentions and began to work with Team Flash to stop whatever he had planned.

Harry worked alongside Team Flash as they unraveled Clifford's history and continued to help them subdue other rogue bus metas that they encountered.

Crisis on Earth-X
During Barry and Iris's wedding ceremony, Harry was present and witnessed the attack by Prometheus-X, Dark Arrow, Overgirl, and the Nazi soldiers of Earth-X as they laid siege to the church.

Following the attack, Harry explained that there was a 53rd Earth in the multiverse outside of the known 52 nicknamed Earth-X due to the horrific conditions on the planet, so much so it was a place no sane person ever traveled to. Harry further explained that Earth-X's timeline was similar to those of other Earths but with one critical difference: the Nazis developed the atomic bomb before the Allies and won World War II, with the Earth-X Schutzstaffel obliterating major cities and establishing outposts throughout Europe and the Americas, later creating the New Reich. He additionally revealed that Hitler continued his brutal reign, supported by world leaders, until his death in 1994.

Harry worked with Team Flash, the Legends, Team Arrow, and Superfriends to prevent Kara Danvers from being killed to save her Earth-X counterpart and stop Earth-X's invasion of Earth-1, during which he learned that Eobard Thawne survived his supposed death at the hands of Black Flash and traveled to Earth-X where he assumed a Harrison Wells likeness (something Harry openly despised) and formed an alliance with the leaders of the New Reich. Despite his best efforts, Harry, along with Cisco, Dinah Drake, and Caitlin, were imprisoned in the S.T.A.R. Labs pipeline as the heroes were captured on Earth-X, allowing Thawne, Dark Arrow, and Overgirl to take over S.T.A.R. Labs in order to transfer Supergirl's heart into Overgirl.

Destruction of Earth-2
He, alongside with every other citizen of Earth-2, with the exception of Laurel Lance, presumably died after a wave of antimatter destroyed Earth-2.

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

- Cisco Ramon

As noted by his daughter, Jesse, Harry was once very similar in nature to his Earth-1 counterpart, being very kind and cheerful with an upbeat nature. However, after losing his wife, Harry grew bitter and 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 the former. 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-2 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 particle accelerator was responsible for the creation of Earth-2 meta-humans, he did not divulge this information to the public, instead trying to profit from the subsequent scare. Harry felt justified in this by the fact that his work was unraveling the mysteries of the universe. It wasn't until Jesse was kidnapped by Zoom did Harry 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 favor 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-1 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-1, as doing so would undoubtedly make Patty a prime target for Zoom, just like his daughter was.

Harry 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 discovered 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-2 Barry to go easy on Earth-1 Barry, after Earth-2 Barry finds out his Earth-1 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-2 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-2 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-2, 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-2, something he would have never done before.

Harry 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 advice from Cisco he learned to consider them his friends eventually.

With his interactions with the far smarter Thinker, Harry has shown a strong 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 even been willing to put himself at risk to boost his intelligence to try matching his intellectual rival. After the creation of his Thinking Cap, Harry became addicted to using the device to the point where he would apply it as a common part of his daily life just for menial tasks, concerning Joe to the point he compared his obsession with using the device to Francine West's drug addiction. Even this dissuasion wasn't able to permanently stop Harry's addiction to the device, as he had became so obsessed with becoming able to outsmart DeVoe that he even finally had Gideon add dark matter to his thinking cap, despite knowing how it had corrupted DeVoe.

This had devastating results, as his neurons were catastrophically killed and he began to steadily lose his intelligence. Effectively disillusioned and finally seeing just how far he had became and now was facing true inevitable uselessness, Harry felt deep shame over this and hid his condition from everyone, effectively disillusioned from using the device, to the point of revealing it to Cisco to stop him from making the same mistake. 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, shortly before which Harry's brain finally expired, going into a catatonic state, often mumbling insanely and mostly despondent, Marlize left a program with Team Flash to restore Harry's intelligence. Although the program gave him a human mind, his memories of his loved ones and knowledge about popular culture, it failed to restore his scientific knowledge but at this point, Harry, having gained a more empathetic and kinder nature as a result, thought of this as a blessing, since for him he now had a balance of mind and heart, and he also became humbled, as he openly admitted to Team Flash that he could no longer be held in regard to his intellect, and no longer possessed 7 PhDs due to the decreased state of his mind.

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-2 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 due to a dark matter overload, Harry's brain damage came with a trade-off advantage of being able to understand others emotions and use them to predict their behavior as he accurately inferred Marlize DeVoe abandoned her husband.
 * Skilled hand-to-hand combatant: Harry has some experience in hand-to-hand combat, as he was able to go head-on with Hunter Zolomon, yet the exact level of his combat skills is unknown, as the fight was broken up by Barry Allen.
 * Expert marksman: Harry has proven himself to be very proficient with his Mercury Labs energy rifle.

Former abilities

 * Genius-level intellect/Master engineer/Scientist: Harry was an extremely hyper-intelligent man, excelling in several fields of science and having 7 PhDs. 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 to effectively recreate the dark matter explosion that gave birth to the first generation of Earth-1 meta-humans. Harry was a master engineer, his most notable inventions being an app that could detect meta-humans, a particle accelerator which caused less damage than the one on Earth-1, 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 permanently damaged, unable to apply his high-level mental performances anymore, which even reached to the point where he entered a catatonic and unresponsive state. Even after the program Marlize created and gave to Team Flash managed to restore him to his original state, he still had lost his scientific knowledge, although it was strongly implied that over time, his full intellectual capability will be eventually reconstructed.

Equipment

 * Mercury Labs energy rifle: Shortly after coming to Earth-1, 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 to figure out the names of the last two remaining bus meta-humans, something the entirety of Team Flash was unable to do.
 * Phasing immunity via nanite infusion: After encountering both Zoom and Savitar, Harry injected a nanobot infusion into his body. This infusion is designed to attack any foreign cells that try to speed into Harry's system, which makes him immune to a speedster's ability to phase through his body (and, as Eobard Thawne loves to do when killing his victims, crush, or completely remove, their heart).

Trivia

 * Harry had repeatedly been mistaken for the counterpart of Eobard Thawne by members of Team Flash despite being the Earth-2 counterpart of the genuine Harrison Wells from Earth-1, as he had to repeatedly correct them. Despite this, the team still continues to differentiate Harry by referring to Eobard as the "other Wells."
 * Due to Thawne's actions on Earth-1 while under the guise of Harrison Wells, Harry is forced to conceal his face by using a cap and sunglasses while out in public. It is unknown whether Harry gained access to HR's identity concealment tech to make this easier, although this is unlikely.
 * There have been few instances where Harry's life was actually in danger because Earth-1 residents believed that he was Eobard Thawne.
 * For example, Harry was nearly fatally shot by police officer Patty Spivot while she was under the impression that he was a criminal. He was on the verge of death before being saved by "Jay Garrick." Likewise, the first time Joe walked into S.T.A.R Labs when Harry was there, he shot on sight and would've killed him if Barry hadn't caught the bullets.
 * Harry was also kidnapped by Griffin Grey as revenge for Thawne's particle accelerator failure which caused Grey to receive super strength but age uncontrollably. Grey demanded that Harry reverse his condition while believing that he was talking to the Earth-1 "Wells." Harry was later rescued by Team Flash while Grey succumbed to his condition and died of old age.
 * Cisco Ramon refers to Harry as the "dickish Wells" due to his poor people skills.
 * Harry's daughter's blood type is PZ Negative, something that doesn't exist on Earth-1. Harry's specific blood type is unconfirmed, but he's stated that he's a compatible match.
 * Harry brushes his teeth front to back.
 * 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-3, 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, having been featured in all four parts of the crossover.
 * 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.
 * Harry is also the first character to have two episodes named after him.

Behind the scenes

 * Harry's blood type, "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-1), Harry Wells of Earth-2 created a Particle accelerator. Unlike Earth-1 "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-2 to stop Zoom. He finalized it in Earth-1. 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)
