Nightmare is a rather evil and solitary Single Father. He had black hair and it covered his left eye in front. His eyes were teal and his skin was very pale. He had many scars or scratches all over his body, not just his face. His body was really muscular. He always dressed in black but elegantly and wore a pair of white gloves, a golden crown on his head with a thin moon-shaped crest on it. He is a mafia boss. He loved reading and to be alone. His son is named Crescent.
