Eobard Thawne

Professor Eobard Thawne (born c. 2524) is a meta-human speedster from the 26th century, a descendant of Eddie Thawne, a time criminal, and the archenemy of Barry Allen/The Flash. Obsessed with the 24th century's Flash, Eobard recreated the accident that gave the Flash his powers and became a speedster himself. But after his very first travel back in time, Eobard learned that he was destined to become the Flash's archenemy and grew to despise the hero, attempting to prove his superiority as the Reverse-Flash and therefore became the opposite of the Flash. Since then, the two speedsters battled one another for many years, but neither of them were strong or fast enough to defeat each other.

After learning the Flash's secret identity, Eobard traveled back in time to kill Barry as a child in an attempt to erase him from existence but he was thwarted when the Flash brought his younger self to safety. An enraged Eobard then killed Nora Allen and framed Henry Allen for the crime instead. However, when Eobard attempted to travel back to his own time, he lost his connection to the Speed Force, becoming trapped in the 21st century. Upon realizing the Flash was the only way to get back to his time, Eobard forged a life for himself as Dr. Harrison Wells, the director of S.T.A.R. Labs, and pushed through for the creation of a particle accelerator to ensure that Barry would become the Flash. This also caused the existence of countless other meta-humans. Posing as Wells, Eobard mentored the Flash to increase his speed so that Eobard could use the hero's connection to the Speed Force to return to his own time. Though his identity was eventually revealed, Eobard moved on with his plan. He was seemingly erased from existence after Eddie killed himself. However, time remnants of Eobard were preserved throughout history by the Speed Force, ensuring that his previous time travels would be left intact.

After some time, Eobard partnered himself with Damien Darhk and Malcolm Merlyn to change their destinies. But Eobard is tracked by Hunter Zolomon, who is now an enforcer of the Speed Force, because him and Barry travelled in time after Flashpoint. He escaped briefly thanks to Damien and Malcolm after he promised to take them as partners.
