Eobard Thawne, known as the Reverse-Flash, is a major antagonist in The CW's Arrowverse, primarily in The Flash. Hailing from the 22nd century, Thawne is a brilliant but embittered scientist obsessed with Barry Allen, the Flash.

Fueled by jealousy and a desire to usurp Allen's legacy, Thawne replicates the accident that grants Barry his speed, becoming a speedster himself. However, he learns his destiny is to be Allen's nemesis and subsequently travels back in time to kill Barry as a child.

This action is thwarted by the future Flash, leading Thawne to kill Barry's mother, Nora, permanently altering the timeline. Stranded in the past without his powers, Thawne assumes the identity of Harrison Wells, a respected scientist, manipulating events to ensure the creation of the Flash. He becomes a mentor to Barry, secretly molding him into the hero he desires to defeat.

Ruthless and cunning, Thawne is driven by a need to erase Barry Allen from existence and claim his role as the Scarlet Speedster. His actions have profound and lasting consequences on the Arrowverse, shaping the lives of its heroes and the world they inhabit.
