Eobard Thawne

Professor Eobard Thawne, also known as Professor Zoom and the Reverse-Flash, is one of the main antagonists of the DC Comics universe, specifically serving as one of the two main antagonists (alongside Gorilla Grodd) of The Flash franchise and media.

He is a scientist from the 25th century obsessed with Barry Allen, the speedster hero known as The Flash, who developed the means to channel the Speed Force in order to replicate the Flash's powers, eventually creating his own Negative Speed Force. After encountering his idol and discovering that he was destined to become the Flash's archenemy, Thawne dedicated himself to destroying Flash's allies and making his life miserable; most notably, killing his mother Nora and framing his father Henry for the crime.

Following the events of Flashpoint, he became a "living paradox"—a being completely disconnected from the timeline—allowing him to use his abilities without consequence, and return from death indefinitely. He is one of the three arch-nemeses (alongside Gorilla Grodd and Captain Cold) of Barry Allen, being his most personal adversary, He also appears as an enemy towards Batman and the Justice League.
