Giganta is a super-villainess appearing in DC Comics publications and related media. A longtime enemy of Wonder Woman and an occasional foil for The Atom, Giganta possesses the superhuman ability to increase her physical size and mass, effectively transforming into a giantess. Her first appearance (Wonder Woman #9, volume 1, published in 1944), written by Wonder Woman creator William Moulton Marston, presents her as a brutish strongwoman with no super powers other than unusual strength. Later adaptations (including appearances on Hanna-Barbera's popular cartoon series Challenge of the Super Friends in the 1970s) introduced Giganta's size-changing ability, a feature of the character which has been retained to date.
