Captain Atom is a nuclear-powered super-hero. Beginning his career in the military as a member of the U.S. Air Force, he was framed for a crime he did not commit; to avoid a death sentence, he was forced to undergo scientific experimentation. His powers stem from an ability to tap into the quantum field. He has also been a member of the Justice League and the Living Assault Weapons.
Captain Atom was created for Charlton Comics by Joe Gill and Steve Ditko, first appearing in Space Adventures (Volume 2) #33. (1960) Cary Bates, Greg Weisman and Pat Broderick reimagined him when Charlton was bought out by DC Comics, beginning in Captain Atom (Volume 2) #1. (1987)
