Brainiac 5 is a member of the Legion of Super-Heroes in the 30th Century. Born on the super-intelligent planet Colu, he is a 12th-level intellect considered a genius even by their standards. This makes him an incredible scientist, inventor, and strategist in combat. His ancestor is the super-villain Brainiac, and he takes this name to redeem his family's lineage. His longest romantic partners have been Supergirl, Andromeda, and Dream Girl. Brainiac 5 was created by Jerry Siegel and Jim Mooney, first appearing in Action Comics #276. (1961)
