DC Comics character

Giganta is a fictional supervillain appearing in DC Comics publications and related media. A longtime enemy of Wonder Woman and an occasional foil for Atom, Giganta possesses the superhuman ability to increase her physical size and mass, effectively transforming into a giantess. Her first appearance, written by Wonder Woman creator William Moulton Marston, presents her as a brutish strongwoman. Later adaptations introduced Giganta's size-changing ability, a feature which has been retained to date.
