This version was a robot who was the hope for mankind. Captain Marvel had a 10-year-old sidekick named Billy Baxton and a love interest named Linda Knowles.

As a civilian, he masqueraded as Roger Winkle, whose occupation varied from journalist to college professor.

Powers and Abilities

Shouting the word "Split" would allow his body to separate down to fingers from hand. Individual parts could fly off independently, doing whatever he willed of them. By shouting, "Xam," he would be reassembled. He also had a pair of astro boots that would allow him to fly into space. His power had to be renewed daily by rubbing the emblem on his chest.
