Reverse flash

Eobard Thawne, also known as the Reverse-Flash. Is a supervillain. 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. Thawne has frequently died, but has made multiple returns through resurrections and time travel. 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.
