Giganta was a super-criminal with the ability to increase or decrease her size at will. She befriended Grodd and became a member of his Secret Society.

History

According to a story Grodd told Clayface, Grodd transformed Giganta from an ape into a human woman with the power to increase her size to tremendous heights, with a proportionate increase in her strength and durability. For this, she was hopelessly devoted to Grodd, and the member of the Secret Society most loyal to him.
