Superwoman is an evil counterpart of Wonder Woman from a parallel universe and a member of the Crime Syndicate of America, a villainous counterpart of the Justice League of America from the parallel world of “Earth-Three” (vs. the Justice League’s world of “Earth-One”). Superwoman, like Wonder Woman, was an Amazon, and possessed similar powers of super-strength and flight. Unlike most/all other versions, her magic lasso could change shape into any form she desired. The Earth-3 Superwoman was created by writer Gardner Fox and artist Mike Sekowsky and first appeared in Justice League of America, Vol. 1, Issue #29 (August 1964).
