Gargouille very much looks like a Gargoyle, giving her gray skin, large bat-like wings which allows her to fly, and sharp horns and talons on both her hands and feet. Her diminutive height (3 feet, 8 inches) and highly dense body are reminiscent of a fantasy dwarf. She has enhanced strength, speed, reflexes, agility and stamina. She has hyper-keen senses to an unknown degree. Gargouille is one of the few mutants to retain their powers after M-Day.
Gargouille was created by John Ostrander, Joe Edkin, and Ivan Reis in 1998 and first appeared in Quicksilver #9
