Captain Atom (DC Animated Universe)

Captain Atom first appeared on the Justice League during the team expansion that followed the Thanagarian invasion of Earth. During his first mission he helped Green Arrow, Green Lantern and Supergirl stop an atomic-powered juggernaut during a rampage through the Chong-Mai region of China, though it caused his containment suit to rupture. He was also part of an orbital defense team that was set up by the Justice League to prevent the evolved Amazo from reaching Earth, to no avail. Later, he was re-commissioned by the U.S. military for the purpose of protecting Project Cadmus and attempted to use his powers to stop Superman and Huntress from taking The Question out of the facility during an interrogation, but was defeated by Superman and brought to the Watchtower for repairs on his containment suit. During that time, Captain Atom helped defend the team from hordes of Ultimen clones that were sent by Project Cadmus to board the satellite and attack them.

He was voiced by George Eads for the episode "Initiation" and Chris Cox for the remainder of the character's appearances.
