Vanny

Vanny is a human woman, Vanessa, who wears a homemade-looking rabbit costume and mask to hide her identity and serve as an alter-ego for William Afton. Her costume is mostly white, with patches of different fabrics like a checkerboard pattern and a blue ribbon around her neck. The mask has a creepy smile and large, glowing red eyes, and she often carries a large knife.  She is psychotic and sadistic.
