Giganta - Wonder Woman: Bloodlines

An enemy of the Amazonian princess Wonder Woman, Giganta joined Villainy Inc. as a mercenary, hoping that she could kill her foe and make a profit while doing it. There she would act as a bodyguard for Doctor Poison, in exchange for chemicals that could increase her strength. 

During a deal between Villainy Inc. and Vanessa Kapatelis, she fought off Wonder Woman, using the mutagen as a power boost. While she was defeated and taken into A.R.G.U.S custody, she did buy Poison enough time to escape with the desired artefact. 

No good to the team now that she was a prisoner, Giganta would be replaced by Cheetah and Silver Swan.
