Cosmo Cat worked as a technician at a munitions plant, when he accidentally set off a bomb, U-235 and gained superpowers. Cosmo Cat resided in his moon lab spotting evils on Earth using his tele-finder and then headed to Earth in his cat-rocket. He was assisted by his sometimes sidekick, Dunky Duck.

During one of his adventures, Cosmo Cat helped to save Little Red Riding Hood from the Big Bad Wolf.

He had flight, super strength, and invulnerability. Cosmo maintained his powers by ingesting "Cosmic Catnip Capsules."
