Eobard Thawne

The Post-Crisis extended origin storyline "The Return of Barry Allen" revealed that Thawne was once a scientist obsessed with the Flash, even undergoing cosmetic surgery to resemble his hero. Obtaining the Cosmic Treadmill from an antique shop, Thawne gained all of the Flash's powers after replicating the electrochemical accident that created the Flash. Seeking to use the Cosmic Treadmill to travel back in time and meet his idol, Thawne arrived at the Flash Museum several years after Barry's death, discovering that he was destined to become Professor Zoom the Reverse-Flash and die at his idol's hands. As a result, the unstable Thawne convinced himself that he was Barry and subsequently attacked Central City for "forgetting him". Wally West ultimately tricked Thawne into returning to the 25th century with no memory of the incident. Despite this, Thawne still managed to bring the remains of his older self's costume with him, cluing him further into his destiny.[7]

After the events of Zero Hour: Crisis in Time!, it is revealed that Malcolm Thawne is Eobard Thawne's ancestor and Barry's long-lost twin brother, meaning that Barry is Thawne's great-uncle.

In 2009, Thawne was re-imagined as a major villain in the DC Universe by writer Geoff Johns in The Flash: Rebirth.[8] His resurrection is foreshadowed to occur in a near-future event.[9][10] It is later revealed that Thawne's recreation of the accident behind Barry's powers made Thawne able to lure Barry out of the Speed Force during Final Crisis and temporarily turn his nemesis into the Black Flash.[11]

When Thawne reappears, he murders the revived Johnny Quick,[12] before proceeding to trap Barry and the revived Max Mercury inside the negative Speed Force. Thawne then attempts to kill Wally's children through their Speed Force connection in front of Linda Park-West, only to be stopped by Jay Garrick and Bart Allen. Thawne defeats Jay and prepares to kill Bart, but Barry, Max, Wally, Jesse Quick and Impulse arrive to prevent the villain from doing so.[11][13] In the ensuing fight, Thawne reveals that he is responsible for every tragedy that has occurred in Barry's life, including the death of Nora Allen (Barry's mother). Thawne then decides to destroy everything the Flash holds dear by killing Iris before they even met.[13]

As Barry chases after Thawne, Wally joins Barry in the time barrier. They reach Thawne and in doing so, they become the lightning bolt that turns Barry into the Flash as they are able to stop Thawne from killing Iris. The Flashes push Thawne back through time, showing his past and future. They return to the present, where the Justice League, the Justice Society, and the Outsiders have built a device originally intended to disconnect Barry from the Speed Force as the Black Flash. Barry tosses Thawne in and Jay activates the device, severing his connection to the negative Speed Force. As the Flashes tie him up to stop him from running, Iris discovers Thawne's weapon back in the past, which she keeps.[14]

In the present, he is imprisoned in Iron Heights. Hunter Zolomon speaks to him, saying they can help each other be better. In Gorilla City, one of the apes warns that Professor Zoom has done something horrible to their jungles, but just what he has done is something even they do not know.[14]

In the 2009–2010 storyline "Blackest Night", the Pre-Crisis version of Thawne's broken-necked corpse is reanimated as a member of the Black Lantern Corps. The black power ring downloaded the corpse's memories, resulting in him not knowing of Barry's death and resurrection. Declaring himself the new "Black Flash", he hunts down and attacks Barry, who manages to elude him for the moment.[15] When the Black Lantern Rogues attack Iron Heights, the living Thawne is encountered and the Black Lanterns' rings strangely malfunction, displaying a strange symbol.[16] When Thawne's corpse approaches his living counterpart, he stops moving and is then frozen by Captain Cold's "cold grenade".[17] Thawne's corpse is brought back to life by the white light of creation, and manages to escape.[18]

In the follow-up "Brightest Day" storyline, the present Professor Zoom is still imprisoned in Iron Heights.[19] When Deadman activates the White Power Battery, the Entity speaks to the 12 heroes and villains resurrected at the climax of the "Blackest Night" and tells each of them of their mission that must be accomplished in order to restore 'life' to the universe and prevent the Blackest Night from ever recurring. Zoom becomes the first to inadvertently fulfill his mission, which occurred in the events of The Flash: Rebirth when he freed Allen from the Speed Force following the resurrection. The Entity proclaims Zoom has completed his task and his life is restored to him, later revealing that Zoom (having fulfilled his task) is now fully purged of all trace remnants of his Black Lantern ties – both present and future.[20] Zoom is released from Iron Heights by Captain Boomerang, who had hoped to better understand his version of the Entity's message. Zoom does not answer him directly, giving a cryptic response and eventually escaping as Captain Boomerang is confronted by the rest of the Rogues.[21]

Thawne uses his powers to completely rewrite his own history; he erases his younger brother from existence and kills his parents when they try to interfere with his research.[22]Thawne later falls in love with a reporter who had been hired to interview him, thus his future self wipes all of the reporter's romantic interests from existence. After finding out his would-be love interest did not return his affections, Thawne's future self traumatized the reporter as a child, causing the woman to be mute and institutionalized so that they never met each other.[22] He later had his younger self find the time capsule containing Barry's costume to make himself the Flash of the 25th century. He sheds a tear as his altered past self runs past him while saying "It won't last long. You will never find love. You will never be the Flash. Barry Allen destroyed my future. It's time I destroyed his.".

In the 2011 Flashpoint storyline, a new timeline is created through the alteration of history.[23] The Reverse-Flash reveals that his body is permanently connected to the Speed Force, enabling him to create a negative version, with which he escaped prison. He was unable to alter Barry's transformation into the Flash, however, as that would effectively erase himself from existence. Instead, Thawne decides to ruin Barry's life during the latter's childhood, killing his mother, Nora. [24] Thawne later reveals that the Flashpoint timeline was created when Barry went back in time to stop the Reverse-Flash from killing Nora. After Thawne is killed by this reality's Batman with a shot to the head, the Flash travels back in time to stop Barry's younger self from altering history but instead, under Pandora's manipulations, a third, new timeline is created, in which DC Comics' continuity takes place from 2011 onward.[25]

In The New 52 reboot of DC's continuity, Thawne's origin is re-established as hailing from the Central City of a 25th-century devoted to the Flash. As a child, Thawne witnessed his father murder his mother and subsequently get arrested. One day, he is struck by lightning and gains the ability to control the flow of time around him, making it appear as if he is moving at superhuman speeds. Believing himself to have been "chosen" by the Speed Force as the Flash's replacement, Thawne dons a costume similar to the hero's and begins to terrorize the Gem Cities as "Zoom", demanding the citizens accept him as a king. However, he is enraged when people rebel against him in the Flash's name.[26] Jealous and bitter that the Flash is worshiped and loved by the people despite their similar powers, Thawne uses Rip Hunter's notes to travel back in time, where he starts recruiting four individuals "touched by the lightning" (the Speed Force) across history, after "saving" them from situations he himself put them into under the false pretense that he requires their help in order to vanquish the "evil menace" of the Flash.[27]

Thawne then makes an acquaintance with Dr. Henry Allen (Barry's father), funding Henry's research lab. But when Henry refuses to help him with an unknown cause, Zoom subsequently murders Nora in order to make Barry endure and give them both an "equal start", and forces Henry to take the blame for his deed, with the threat of Barry's life. Laying low for many years, Zoom reemerges following William Selkirk's defeat, recruiting as an "acolyte" of his. Zoom and his acolytes then cause havoc in the city and put the blame on the Flash, desiring to destroy his nemesis's legacy.[28]Thawne then kidnaps Henry when some inmates escape from prison in order to divert Thawne's attention away from Barry, and forces Henry to construct a power-stealing glove. But when his closest "ally" Magali (who has been keeping Thawne alive for centuries via powers) discover the truth about him, he uses the glove to steal Magali's abilities of affecting the age of organic and inorganic matter, leading to his true nature being exposed to the rest of his acolytes, who join forces with the Flash to destroy the device.

After the failure of his plan to be a god, Zoom then takes Henry to the Allen house, with Barry in pursuit. Revealing his backstory to Barry, Thawne proceeds to best Barry in combat and is about to kill him until the Flash realizes how Thawne's powers work, and then proceeds to counter by moving time forward – finally defeating him. After talking Henry out of killing Thawne, Barry has him arrested and imprisoned at Iron Heights Penitentiary.[26]

The serial-killing speedster Godspeed later attempts to kill Thawne and every other inmate at Iron Heights as a twisted gesture of friendship to Barry, only to be stopped by the hero.[29]

In the DC Rebirth relaunch, Thawne's powers are retconned back to Negative Speed Force superspeed, his origin is revised to be closer to his pre-Flashpoint ones (albeit with some differences and an altered motive), and the Reverse-Flash mantle is returned to him, now as his primary moniker. In spite of these retcons, his New 52 history is shown to have somehow still occurred, to some extent.[30][31]

An only child when his parents died in an accident, Eobard Thawne grew up obsessed with the Flash. After finding a time capsule with the speedster's costume, he uses traces of the Speed Force in it to turn himself into a Flash. Due to a lack of threats in the 25th century, Thawne creates his own by endangering people, before "saving" them. He is overjoyed when Barry Allen travels to his time and teaches him new tricks, but his deceit is soon found out. After Barry defeats him and has him arrested, Thawne promises to rehabilitate himself, to that end undergoing therapy and becoming a professor. He also eventually becomes the curator of the Flash Museum. Seeking to show Barry how much he's changed and become his partner, Thawne travels to the past. However, he is enraged after he witnesses Barry give Wally West a talk on how "every second is a gift", similar to one that Barry gave him, and realises that he wasn't treated specially by the Flash. Still seeking to spend time with the Flash and be his friend, Thawne becomes the Reverse-Flash, vowing to making Barry's life a living hell until he learns to "make time" for him.[30][31]

Leading up to the 2017 "The Button" crossover, Thawne's memories of his Pre-New 52 self are restored after a mysterious wave of energy strikes him, and he recalls being killed by Batman (Thomas Wayne) during Flashpoint.[32] Seeking to teach the Dark Knight's son a lesson, Thawne attacks Bruce Wayne in the Batcave and destroys Thomas's letter as retribution. Thawne brutally beats and verbally taunts Bruce before picking up the Comedian's smiley-face pin, which teleports him away to an unknown location. Thawne is then teleported back to the Batcave, having been bathed in radiation by a mysterious entity. As he collapses, Thawne says "God...I saw...God."[33] After discovering traces of his energy siganture on Thawne's corpse, Barry ponders if he kills the Reverse-Flash at some point in his future (but Thawne's past).[34] Batman and the Flash come across Thawne in possession of the Button shortly before his apparent death, and follow him in an attempt to prevent it.[35] As he follows the traces leading to the entity, Thawne muses that he may go back in time to raise his nemesis as a "family friend" after killing Nora, but is killed by Doctor Manhattan and teleported back to the Batcave.[36]

In the aftermath of "The Button", Thawne's corpse is taken to S.T.A.R. Labs, but he is resurrected via his connection to the Negative Speed Force and returns to the future, to examine the difference between the pre and post-Flashpoint timelines. He is present at Iris West's house when she arrives with Wallace West,[37] who Thawne brutally beats and denounces as a fake, before kidnapping Iris and bringing her to the 25th century.[38] When Barry arrives, he is quickly beaten by Thawne, who reveals his identity as the Flash to Iris. Thawne subsequently shows the couple's future and tricks Barry into becoming trapped in the Negative Speed Force, but Flash becomes connected to it and escapes. A pleased Thawne implores Barry to "ditch the loser sidekicks" and become his friend and partner, but Flash refuses and strips him of his speed. Nevertheless, Thawne vows to regain his powers and keep coming back to torment Barry, before being killed by Iris with a vaporisation gun.

It is later revealed that Thawne pulled Thomas Wayne out of the Flashpoint timeline just as Manhattan erased it, in order to torment Thomas with the main timeline, where Bruce is Batman.[39]

Thawne is revealed to be the only person to have defeated the chronokinesis-wielding new Flash villain, Paradox.[40][41][42] To learn how to do so, Barry pulls an earlier version of Thawne out of the timeline, from the night he killed Nora.[43]

Eobard Thawne, as the Reverse Flash, appears in Justice League Adventures #6 (June 2002).

In an alternate timeline created when Impulse kills an insect in the Devonian Age, most super-villains are government bureaucrats. Professor Zoom is the National Science Advisor to President-for-Life Julian Tremain. In subsequent changes to the timeline, Zoom defected to the rebellion against Tremain led by Gorilla Grodd; turned into a gorilla fighting against an army of flying turtles led by Grodd, now a flying turtle himself; and was a gorilla in a modern society identical to that of ancient Egypt.[46]

• Thawne first appears as the main antagonist of Justice League: The Flashpoint Paradox (2013). He hires the Rogues to ambush the Flash (Barry Allen) at the Flash Museum before betraying them by placing explosives on their belts. The Justice League then arrive to disarm the bombs and apprehend Thawne. Barry travels back in time to prevent Nora Allen's murder and inadvertently alters all of reality, creating a world where Aquaman's Atlantean army is at war with Wonder Woman's Amazon forces. Thawne also enters this reality via the Speed Force, saving Lois Lane from the Amazons to alert Barry of his presence. While Cyborg's metahuman team tries to put an end to the war, Thawne appears and subdues Barry. As the Atlanteans' doomsday device destroys the world, Thawne is shot in the head by Batman, thus allowing the Flash to tap into the Speed Force once more to stop Barry's past self from altering time, effectively creating a new reality similar to the original.
• Thawne returns as the main antagonist in Suicide Squad: Hell to Pay (2018), set in the new reality. It is revealed that Thawne managed to stretch his last moments before death by months, consolidating his speed to keep himself alive despite having a gaping gunshot wound in his head from Batman's gun, and was able to use the Speed Force to phase into the new timeline with his memories mostly intact. Living on "borrowed time" due to only possessing a limited amount of Speed Force energy left and forced to use his powers sparingly or accelerate the time of his death, Thawne attempts to acquire a "Get Out of Hell Free" card which would allow him to escape his fate, only to be killed when Bronze Tiger cuts off his fingers so that he would drop the card before Deadshot shoots him through the head once again. A version of Zoom native to this timeline is mentioned by Deadshot, and mentions they used to know each other, which he comments on the second Thawne's handicap, noting he wasn't nearly as weak before and never needed help from other villains.
