First appearance: The Flash #139 (1963)
Created by: John Boome and Carmine Infantino
Most villainous act: Killing the Flash’s wife.

Sure Batman and Spider-Man’s villains are household names, but the most diverse and underrated rogues gallery in the comic book world belongs to The Flash. And who better to highlight than his mirror image, Eobard Thawne, a.k.a. Professor Zoom, a.k.a. The Reverse Flash? This inverted menace isn’t just about posturing and ego like other villains. Possessing the same super speed as The Flash, Thawne made a name for himself by vibrating his hand through the chest of The Flash’s fiancé, Iris West. Damn.

The backstory of Thawne is complicated, involving time travel and cosmic treadmills that we simply don’t have the patience to recount here. Boiled down to its essence, Professor Zoom is a man who traveled back in time to become a hero like The Flash, but his homicidal tendencies drove him down a path to comic book infamy. Ultimately, this bitter rivalry culminated in shocking fashion when The Flash broke Thawne’s neck to protect the new love in his life. Double damn.
