In his comic book appearances, Professor Eobard Thawne is depicted as a scientist from the 25th century who originally idolized the Flash. He replicated the accident that gave the Flash his powers, but was driven insane and became obsessed with ruining the Flash's life upon learning that he was destined to become his greatest enemy–the Reverse-Flash. Fueled by jealousy and hatred, Thawne travels throughout time to torment and destroy the Flash's life. He has been established as one of the fastest speedsters in the DC Universe. Thawne has frequently died, but has made multiple returns through resurrections and time travel.
