Eobard Thawne (Earth-Prime)

"Almost two centuries from right now, we meet for the very first time. For my part, I'd finally discovered ways to possess speeds. Speeds faster than anyone alive. And just as I was about to present myself to the world... You showed up in pursuit of some stupid case, dazzled the crowd. Ah, you were dazzling. And then... and then you saved the crowd. A crowd that I was meant to save. A crowd that was meant to thank me. You stole my greatest moment. I admired you. And you humiliated me. And it was in that moment that I knew that I had to get faster than you."

- Eobard to The Flash

Professor Eobard Thawne is a metahuman time criminal and arch-enemy of The Flash, who operated under the alias of the Reverse-Flash.

Early Life
Eobard Thawne was born at some point in the twenty-second century, coming to idolise the twenty-first century hero, The Flash, to the point of searching for a way to gain superhuman powers similar to his. He eventually successfully built a Speed Force machine which granted him these powers, becoming a speedster and the fastest man alive. As he was about to reveal his abilities to the world, The Flash showed up in pursuit of a case, dazzling the crowd by saving them from a danger which Thawne believed was his to deal with. This began a lifelong hatred of The Flash, with Thawne making it his life's work to become faster than him in order to ruin his life. In this pursuit, he created the Negative Speed Force to power himself, and created a suit with the reverse colours of The Flash, which he used to become the criminal known as the Reverse-Flash.

Life as Harrison Wells
Thawne eventually learned of The Flash's true identity and so travelled back in time to the year 2000 to kill Barry Allen, though he ended up killing Nora Allen instead, resulting in him being trapped in the twenty-first century. He then killed Dr. Harrison Wells, stealing his identity using the appearance-stealing cord, and burying Wells using his superhuman speed, though he was resurrected moments later to balance out the loss of the other versions of Wells from the multiverse. Now operating as Harrison Wells, Thawne founded S.T.A.R. Labs, forming a close relationship with Hartley Rathaway. He, alongside Caitlin Snow, were also responsible for testing Grodd, with the pair becoming quite fond of him and often visiting him in his cage.

Encounters with Team Flash
Eventually, Thawne began creating a particle accelerator, which he set to explode in 2013 in an attempt to return to his own time. This resulted in numerous people becoming metahumans, including leading to Barry Allen becoming The Flash. For months afterward, Thawne trained Barry to become a hero, including teaching him to throw lightning. Numerous events during this time period occurred differently than they did on Earth-1, as shown by both Girder and Everyman still being alive, and Hartley Rathaway still being a villain. Thawne was eventually defeated in 2015 after his ancestor, Eddie Thawne, committed suicide in order to erase him from the timeline, resulting in the singularity occurring. However, a version of Thawne did survive after he was pulled from the timeline by Barry during Flashpoint, ultimately surviving as a time remnant.

At some point after this, Thawne was resurrected. He later met Nora West-Allen, who wrote information about the Negative Speed Force in her journal before being erased from the timeline. Thawne also kept notes on how to create an artificial Speed Force.

Possessing Nash Wells
A few months after the creation of Earth-Prime, the consciousness of Eobard's pre-crisis counterpart was transferred into the body of Nash Wells, due to his DNA and appearance matching the other Wells doppelgängers, and he saw this as an opportunity to regain a physical body. The other Wells doppelgängers restrained Thawne in Nash's subconscious, while Harry and Sherloque attempted to get Nash to seek the help of Team Flash. However, Thawne managed to escape before they could be alerted, trapping Nash in his own memory of losing his adopted daughter, Maya.

Once in control of Nash's body, Thawne attempted to murder Cisco Ramon, only to realise that he no longer had his powers. After a short fight with Cisco, Thawne was incapacitated by Cecile Horton and locked in the Pipeline. He was then interrogated by Barry Allen, revealing his goal was to kill him and his loved ones, before taunting him over the death of the Speed Force.

Hours later, Thawne began to impersonate Nash, managing to trick Team Flash into activating his gauntlet, which generated a pulse of energy that allowed him to escape. He attempted to flee using a time sphere, but was prevented from doing so by The Flash, who he then attempted to trick into using his last remaining speed to kill him. However, he was prevented from doing so by Cisco, who used a tranquillizer to subdue him. After Cecile transported Barry and Cisco's consciousness into his body, Nash managed to overcome the memory of Maya dying, resulting in Thawne being expelled from his body and being reduced to negative tachyons.

Godspeed War
During the Godspeed War, The Flash, and Iris West-Allen realised that Godspeed's ability to siphon speed from Speed Force users meant that they couldn't defeat him on their own. For this reason, the Speed Force connected to the Negative Speed Force in order to reconstitute Thawne's body so that he could assist The Flash in battle. Once he regained his physical form, Thawne attacked Godspeed before greeting The Flash, and the pair then engaged Heart with swords made of lightning. They managed to distract Godspeed long enough for The Flash to surprise him with a sonic boom and for Thawne to impale him with his sword.

Worried that Thawne may have killed Heart, The Flash rushed to check his vitals and was relieved to find that he was just knocked unconscious. Barry then scolded Thawne for this, though he merely responded that he should have been prepared for that possibility when they reached out to him for help. Thawne then attempted to punch Barry at superspeed, but was thrown forward after Barry entered into Flashtime. Frustrated that The Flash was now faster than him, he asked how this was possible, with Barry responding that he had gotten faster, mockingly asking Thawne if he had not done the same. Thawne responded that he had not before telling Barry that he will return once he had and running off.

Reverse-Flashpoint
After his humiliating defeat by The Flash, Thawne created the Negative Still Force to change timeline without being detected. He used this to change numerous events, including planting evidence associating Barry with Black Hole, causing a radiation leak at S.T.A.R. Labs, and murdering Joe West, all of which eventually lead to Armageddon. He was also responsible for the attack on Central City while wearing The Flash's face, travelling back in time to murder the 11-year-old Barry Allen, and making it so he was struck by lightning and thus became the leader of Team Flash and the fiancé of Iris West, all of which created a Reverse-Flashpoint.

The involvement of the Negative Still Force in changing the timeline was eventually noticed by Iris West and Deon Owens, who used his powers to send Barry ten years into the future to discover who was altering the timeline. Once he arrived in 2031, Barry interrupted a speech by Thawne at Robern's in which he stated to some of Barry's friends that he was engaged to Iris West. Barry and Thawne then suited up, revealing to Barry that they were in the opposite suits to what they would be in the original timeline. The two fought briefly, with Barry throwing a lightning bolt at Thawne, only for him to be saved by Ryan Choi using Ray Palmer's shrink ray. Once the battle was over, Barry brought Iris outside to convince her that he is actually her husband, but Thawne followed him and confronted Barry. He then revealed all the changes he made to the timeline and that Barry would be completely erased from the timeline at midnight.

Some time later, Thawne confronted Barry again as he was trying to convince Iris of who he really was, only for Thawne to be temporarily paralysed by Iris. The Flash then attempted to travel through time to undo the Reverse-Flashpoint, only to be chased by Thawne. Running this fast resulted in the planet being destroyed, but this reversed by Barry after the timeline was reset. Thawne then arrived in 2021 wearing the version of the Reverse-Flash suit that Barry had been previously, and stating that he would change the timeline again from inside the Time Vault.

Avoiding Fate
Not long afterward, Thawne began to notice that he was being erased from existence, due to the effects of the time stone, and so he decided to run to the Central City Police Precinct to get the attention of The Flash. Instead, he was met by the Green Arrow, who believed he had something to do with William Clayton's disappearance. As Thawne was being interrogated, he began to fade out of existence before attempting to kill Mia. However, he was prevented from doing so by The Flash, and he then admitted he was there to get his help.

He was then taken to S.T.A.R. Labs and placed into a forcefield to monitor his condition and to ensure that he does not hurt anyone. As Team Flash and the Green Arrow were discussing how to deal with Thawne, he was visited by Caitlin and told that he had two hours before he was erased from the timeline. Thawne then gloated about Caitlin being with Team Flash rather than having lived a future with Ronnie Raymond, before stating that despite this taunting, she would not let him die due to being a doctor. Caitlin then replied, stating that she has hated him for eight years for being responsible for Ronnie's death. After this conversation, Barry entered the room and asked Thawne why he created the Reverse-Flashpoint timeline and why he hated him so much in the first place. Thawne then recounted how Barry had supposedly stolen his opportunity to become a hero at some point in the future, and how this led him to his hatred of The Flash. Barry responded that only a sociopath would react to something so small with that kind of rage, though Thawne replied that what he calls rage is what he calls commitment. He then stated that he would go right back to finding new ways to kill The Flash if he were saved.

After debating what to do about Thawne, Team Flash decided to save him despite everything that he has done, whereas Despero decided that he must be killed to prevent further damage to his time period. He then attempted to control Mia in order to kill Team Flash, though she was unsuccessful, and The Flash later defeated Despero. With thirty seconds remaining before Thawne was erased from existence, Barry used his lightning to sever Thawne's connection to the Negative Speed Force, saving his life but also removing his powers. He was then transported to an A.R.G.U.S. prison.

Possible Future
In a possible future visited by Despero, Thawne had returned once again and had regained his connection to the Negative Speed Force.

Former Powers

 * Speed Force/Negative Speed Force Connection: Thawne possessed a natural connection to the Speed Force after he recreated the accident that gave his idol, Barry Allen, his powers. After discovering that he was destined to become the arch-enemy of The Flash, he gained a connection to the Negative Speed Force to avoid the limitations of the Speed Force. This connection was later severed by The Flash in order to save his life.
 * Accelerated Healing Factor: Thawne's body healed much faster and more efficiently than regular people, meaning he could survive injuries that would prove fatal to most people.
 * Bodily Vibration: Thawne was able to vibrate his body on command at different frequencies, which meant that his face was not clearly perceivable by normal people.
 * Electrokinesis: Thawne's body produced red lightning, which he could throw as a weapon or use to turn his eyes red.
 * Electrical Constructs: Thawne was able to create as sword made out of lightning during his fight with Godspeed.
 * Superhuman Durability: Thawne was able to endure attacks and impacts which would prove fatal to normal people.
 * Superhuman Perception: Thawne was able to think and preform actions before most people could perceive them.
 * Superhuman Senses: Thawne's senses were much greater than the average person, allowing him to hear properly even when exceeding the speed of sound.
 * Superhuman Speed: Thawne was able to move at superhuman speeds, to the point where he was able to run on walls and ceilings with ease.
 * Superhuman Agility: Thawne was able to maintain superhuman coordination and balance whilst running on unstable surfaces. This allowed him to change direction immediately whilst running at superhuman speeds.
 * Superhuman Momentum: Thawne was able to generate and withstand extreme kinetic energy and completely stop when running at superhuman speeds.
 * Superhuman Reflexes: Thawne was able to respond to events much faster than normal people.
 * Time Travel: Thawne was able to travel through time by creating a portal to the Negative Speed Force.
 * Time Remnant Creation: Thawne was able to create a time remnant of himself, which protected him from being erased from the timeline.
 * Superhuman Stamina: Thawne was able to run at superhuman speeds without becoming visibly tired or weakened.
 * Superhuman Strength: Thawne was able to generate immense amounts of physical force and direct it at his opponents.
 * Possession: After the Crisis, Thawne survived as negative tachyons, which allowed him to possess Nash Wells. He lost this power after he was given a physical body by the Speed Force to assist The Flash during the Godspeed War.

Abilities

 * Genius-Level Intellect: As a scientist from the twenty-second century, Thawne is an exceptionally intelligent individual.
 * Business Acumen: Thawne is a skilled businessman as he was able to found and effectively run S.T.A.R. Labs for fourteen years before his defeat by Team Flash.
