The Mask: The Animated Series
Dr. Pretorius: The main villain (See Villains section). Pretorius is a unique Mask wearer as he completely managed to retain his personality and consciousness in control, possibly due to him having no inhibitions which the mask releases in the wearer. He tries to kill Stanley and Peggy by eating them, but is defeated after his invention Sister Mask is used against him. Pretorius wore the mask in Sister Mask.
