Eobard Thawne (Arrowverse)

Hailing from the 22nd century, Professor Eobard Thawne was obsessed with a superhero speedster known as the Flash, and eventually managed to replicate the accident that gave him his powers, inadvertently creating a "negative" version of the Speed Force.[1][2][3] However, Thawne became bitter and jealous when his idol, having traveled through time, saves a crowd that Thawne had intended to rescue.[4] Upon traveling through time himself and learning that he was destined to become the Flash's greatest enemy, Thawne became obsessed with ruining his former hero's life as the Reverse-Flash.[1][5] At some point, Thawne traveled to the year 2016 and learned what time period the Flash hailed from.[1] The two would battle each other across centuries, with both speedsters equally matched and neither ever prevailing.[6]

Thawne eventually learns of the Flash's secret identity–Barry Allen–and travels back in time to the year 2000 to kill him as a child. In this time period, he encounters a version of Barry from the year 2023, who warns Thawne of the potential consequences of his actions. Barry attempts to convince Thawne to give up his hatred and end their rivalry for good, but Thawne refuses and continues his attempt to kill Barry’s younger self.[7] When his plan fails due to the 2023 Barry's interference, Thawne kills Barry’s mother Nora and frames his father Henry instead, hoping that losing his parents will cause the Flash to cease to exist. In doing so, Thawne inadvertently severs his own connection to the Speed Force, stranding himself in the 21st century.[8] He murders and assumes the identity of Dr. Harrison Wells to found S.T.A.R. Labs and spends the next fourteen years building a particle accelerator with the intention of creating the Flash ahead of schedule.[9][6] As Wells, Thawne mentors Barry in defeating metahuman criminals created by the explosion of the particle accelerator and helps to increase his protege's speed with the goal of using Barry's pure connection to the Speed Force to return to his own time.[10][11] Thawne also taunts and bests Barry in combat as the Reverse-Flash to push Barry into getting faster.[12][13]

After Thawne's secret is discovered, Barry captures him with the help of Oliver Queen, Ronnie Raymond and Martin Stein.[14] Thawne offers Barry a chance to travel back in time to save Nora in exchange for a time machine to return to the future once the Speed Force wormhole is open, but Barry ultimately refuses and destroys Thawne's machine. Before Thawne can kill Barry, one of his ancestors, police detective Eddie Thawne, shoots himself which seemingly erases Thawne from existence.[6] A flash drive containing Thawne's will as Wells both bequeaths S.T.A.R. Labs to Barry and includes a video-recorded confession to Nora's murder, which allows for Henry's exoneration.[15] Barry would travel back in time and return to this period in which Thawne masquerades as Wells to seek Thawne's help on multiple occasions.[16][17][18]

Thawne survives his erasure following Eddie's sacrifice because of his connection to the Negative Speed Force, which is immune to timeline changes.[19][20] He allies with Dark Arrow and Overgirl of the Nazi-dominated Earth-X to invade Earth-1.[21] During the final battle, Barry defeats Thawne but spares his life, and Thawne speeds off while his allies are killed.[22][23]

Thawne is captured and imprisoned in Iron Heights Penitentiary in 2034.[24] He is sentenced to death and routinely tortured by a corrupt prison guard[24] while a dagger that had belonged to the metahuman serial killer Cicada[20] dampens his super-speed. In 2049, Barry and Iris West-Allen's future daughter, Nora West-Allen, seeks Thawne's help in solving a police case and controlling her own newly discovered super-speed.[24] Thawne becomes Nora's mentor and claims that he seeks to create a more noble legacy for himself before his execution,[18][5][24] but he actually plans to destroy Cicada's dagger and escape Iron Heights, so he sends Nora to travel back in time and help Barry defeat Cicada. Thawne's plan succeeds as the dagger is destroyed, freeing him moments before his execution in 2049. He briefly fights Barry, Nora, and Team Flash before Nora begins fading from existence because of the changes in the timeline. After Barry witnesses Nora's temporal erasure, Thawne makes his escape.[20]

Thawne becomes a being of negative tachyons and is fused with Harrison Nash Wells following the multiversal Crisis, after which Nash becomes the 'repository' for the consciousness of every version of Wells, which includes Thawne because of his time spent as Wells. Thawne takes control of Nash's body, but Barry captures Nash and imprisons him in S.T.A.R. Labs.[25] Before Thawne can regain his connection to the Negative Speed Force, Team Flash expels him from Nash, leaving him bodiless.[26]

Barry and Iris later have the Speed Force reconstitute Thawne's corporeal form in exchange for his aid in subduing Godspeed. Thawne double-crosses Barry by incapacitating Godspeed before making an attempt on Barry's life, but Barry easily defeats him. Seeing that Barry is now faster than him, Thawne vows revenge and flees.[27]

To seize control of Barry's life as revenge, Thawne uses the Negative Still Force to alter the timeline and create a "Reverse-Flashpoint" reality in which he is the Flash and Barry is the Reverse-Flash. Barry uncovers Thawne's machinations and reconnects to the Speed Force to avert the impending "Armageddon" and restore the timeline,[28] causing Thawne to begin fading from existence. To save Thawne's life, Barry strips him of his powers and has him remanded into A.R.G.U.S. custody.[4]

Incarcerated in a supermax prison on Lian Yu, Thawne is visited by John Diggle who seeks his help in unlocking a mysterious cube. Seeing it as a chance to escape, Thawne helps open it but is frustrated when Diggle declines its power. The Negative Still Force materializes in Thawne's cell, seeking to restore him as the Negative Speed Force's avatar after Barry severed his connection to it. To that end, Thawne is aged to death before Iris is sacrificed so that he can be "resurrected" in his redeemed time remnant's body, allowing him to be the Reverse-Flash once again.[29]

After taunting Barry, Thawne goes into the Negative Speed Force and absorbs the powers of the other Negative Forces, which transforms him into their avatar. Thawne attacks Central City and kills dozens of civilians until Barry absorbs the powers of all the Positive Forces to be Thawne's equal. The two speedsters engage in a battle that threatens to bring about Armageddon and destroy the city. Realizing that neither of them will ever win, Barry surrenders and tricks Thawne into unleashing the full power of the Negative Forces, only to redirect the negative energy back into him, destroying Thawne for good.[30]

After losing his father to Zoom, Barry decides to travel back in time and save his mother from Thawne, creating an alternate "Flashpoint" timeline in which Thawne is imprisoned. Barry realized the mistake in manipulating time and releases Thawne and allows him to kill Nora to restore the timeline.[31]

Once he escapes the Flashpoint timeline,[31] Thawne enters a nullified state of existence as a time remnant,[32] causing him to be hunted by the Black Flash, the Speed Force's demonic enforcer.[33] Seeking to cement his existence, Thawne forms a legion of villains to locate the fabled Spear of Destiny.[32][34] While Thawne and his co-conspirators succeed in using the Spear of Destiny to rewrite reality to their whims,[35] the Legends travel back in time to de-power the holy object, causing him to be vaporized by the Black Flash.[36]

Sometime later, the Speed Force brings Thawne's time remnant back to life, removes his powers and assigns him to defend the assassination of Archduke Franz Ferdinand – a "fixed point" in history – from time travelers. When the Legends visit the fixed point to attract an evil Gideon's attention, Thawne decides to aid the group.[37] Thawne is then killed by Sara Lance's android doppelgänger, after which Nate Heywood's android doppelgänger is tricked into taking his place as the fixed point's defender.[38]

As a reward for his sacrifice in protecting the timeline, Thawne's time remnant is offered an opportunity for redemption when the Speed Force resurrects him without his memories. Feeling inexplicably compelled to be a speedster again, he works with Dr. Meena Dhawan, CEO of Fast Track Labs, to create an artificial Speed Force device. Thawne falls in love with Meena and sacrifices his dream when he uses their invention to save Meena's life via super-speed after she suffers a cardiac arrest, inadvertently connecting her to the Negative Speed Force. Thawne later works with Barry to free Meena from its corruption.[3] This time remnant of Thawne is ultimately sacrificed by the Negative Forces so that the original timeline's version of Thawne can be revived, much to Meena's horror.[29]

Cavanagh has stated many times that he enjoys playing the character of Eobard Thawne as the character is interesting, complex, and challenging.[46][47][48] When speaking with the Television Academy about playing Thawne he said: 'The Reverse Flash has what I like to a call timeless way of speaking. He doesn't use colloquialisms from 2016, he's a little more formal, and he takes joy in destroying people. He has a larger perspective because he comes from 100-plus years in the future and has seen it all. It's easy to play a character like that. He's the arch in arch-villain.'[49] He also sat down with Rolling Stone to discuss his supervillain voice in which he said: "If you're doing it right, you can be charismatic, you can win people over, and you can have so much fun. You build a cage and then you just rattle that cage more than the leading guy can a lot."[50] Kreisberg insisted that Thawne was not evil because his fatherly affection for Cisco was genuine, and "he has a reason for doing what he's doing and he has an agenda and he thinks of himself as the hero ... bad people are capable of incredible amounts of kindness and generosity".[41] Though Thawne is frequently shown to return from death throughout his appearances, Eric Wallace (The Flash showrunner since 2019) intended for his death in the season eight finale to be permanent.[51] However, Letscher returned as the character in the ninth and final season, as Wallace stated that they wished to bring Letscher one more time for a "bittersweet" episode featuring Thawne, later revealed as "A New World, Part One".[52] Wallace later confirmed that Cavanagh would return one final time for the series finale "A New World, Par Four", feeling that Barry Allen's story had to end with one last confrontation with his archenemy, assuring that bringing the Reverse-Flash back for the finale was always part of the show's plan.[53]

When asked by the Television Academy about wearing the Reverse-Flash suit, Cavanagh replied with "That's a lot of what acting is. Often times, you're tapping into the things you did as a youth. You pretended. A lot of us pretended to be Batman, to be our favorite super-hero. A lot of times, you pretended to have the power of imagination at your side. And the first time you put it on, the cameras are rolling, and off you go at superspeed. I've gotten to do some great, great thrilling stunts in the suit. It is a dream come true. I understand that it's a job, and I'm getting paid, but the second that a director yells, "Action", all that disappears, and you're a guy in a supersuit. It's extremely thrilling. I've said before that I wish that anyone who is a legitimate comic book fan could have this opportunity. It really feels like a privilege."[49] Cavanagh also said "I benefited from all the trial and error that went into that. ... I think they did a marvelous job with the suit, I'm always very flattered and honored to put it on," when speaking with Access Hollywood.[54]
