Zzzax (Marvel Animated)

Zzzax was formerly technician Mitch McCutcheon who attempted to help Robert Bruce Banner use machines at a research facility to remove the gamma radiation from his body. Unfortunately, the experiment was interrupted, charging McCutcheon with electrical energy and transforming him into Zzzax. He battled the Hulk for a time, draining more power, until he was dunked in the waters of Hoover Dam and restored to normalcy.
