History
Hunter Zolomon was a survivor of tragedy. His parents had died on the same day, his mother killed by his father, and the police killed his father. He worked for a career in the FBI, but he made a mistake that led to the death of his father-in-law, his wife leaving him, a bad knee, and his discharge from the bureau. He tried once more to build a life in Keystone City as a profiler with their police department, which made him a target for Gorilla Grodd, who broke his back with a single snap, leaving him paralysed from the waist down.Hunter was driven into the depths of depression by his feelings of helplessness, and insisted the Flash take him back in time to prevent the mistake that cost him everything. The Flash knew first-hand that changing history can easily make things far worst and refused. Undeterred, Hunter took the F.B.I.'s theories on the workings of the Cosmic Treadmill and attempted to hot-wire the device so that he could use it himself. Instead it exploded, taking the Flash Museum with it, and shifting Hunter onto a faster timeline, effectively giving him super-speed. With his grasp on reality deteriorating, Hunter latched onto a recent discussion about Professor Zoom, and decided he needed to become a new Reverse Flash. He would make the Flash face ultimate tragedy. He would force the hero to understand he must risk everything to prevent it. Zoom was born.
