Eobard Thawne

Born in the far future, Eobard Thawne became obsessed with the legacy of the Flash, ultimately using reverse-engineered Speed Force technology to grant himself super-speed — and transform himself into the Flash's most personal and dangerous enemy, Professor Zoom, the Reverse-Flash.

Few villains in DC's Silver Age canon have cast as long a shadow as Eobard Thawne, who first menaced readers in The Flash #153 back in 1965. Emerging from that era's rich tradition of speedster mythology, Thawne has kept remarkable company across six decades — sharing pages with Barry Allen, Wally West, Green Lantern, and even Batman — a roster that speaks to just how deeply he's woven into the fabric of the DC universe. His appearances span The Flash and Batman titles across roughly sixty years, a testament to a character whose pull on collectors and readers alike has never faded. With a key issue already on the books and a presence that stretches from the Silver Age all the way to 2025, Thawne is essential reading for anyone serious about DC history.
