The inspiration for Dr. Manhattan, Captain Atom is another old-school hero. In the Charlton Comics version, he was a technician who accidentally launched in a nuclear rocket, and it exploded, although the technician got powers from the radiation.

It fused to his body a metal with energy-absorbing properties and thus he became Captain Atom under a government program.
