Mutant Zero

Mary has dissociative identity disorder, causing her to have two other abnormal personalities in addition to her main, seemingly normal one. "Mary" is a demure, quiet pacifist; "Typhoid" is audacious, lustful, and vicious; and "Bloody Mary" is merciless, brutal, and hates all men. Mary occasionally manifests a fourth personality, "Walker", who acts as a moderating influence on the others.
