Eobard Thawne (Arrowverse)

Eobard Thawne, also known as the Reverse-Flash, is a character in The CW's Arrowverse media franchise. Based on the DC Comics supervillain of the same name, he is primarily portrayed by Tom Cavanagh and Matt Letscher. Letscher played the character's original likeness, while Cavanagh portrayed him in the form of Harrison Wells. Thawne is introduced and featured most prominently in the television series The Flash, though he has also appeared in spin-off shows and crossover events set in the shared fictional universe.

As in the comics, Professor Eobard Thawne is depicted as a scientist-turned-metahuman criminal speedster from the future and the archenemy of Barry Allen / The Flash. He originally idolized the Flash and replicated the accident that gave him his powers, but became obsessed with ruining his life upon learning that he was destined to become his greatest enemy–the Reverse-Flash. After traveling back in time, Thawne inadvertently strands himself in the 21st century and is forced to orchestrate the Flash's creation to return to his own time period. He has since returned to torment the Flash numerous times, which has brought him into conflict with other heroes, including Green Arrow, Supergirl, and the Legends.
