Power Girl is the Earth-Two equivalent of Supergirl, native Kryptonian and cousin to Superman. Her origins have changed several times in continuity when the Multiverse was erased Post-Crisis. The distinctive costume she wears lacks an emblem, and she uses this as an advantage to distract others in combat. She has been a member of the Justice League, the Justice Society, Infinity, Inc., Birds of Prey, the Suicide Squad and the Sovereign Seven. Power Girl was created by Gerry Conway, Ric Estrada and Wally Wood, first appearing in All-Star Comics #58. (1976)
