He is a mute and experienced assassin, always giving all three Angels a run for their money in a fight.
He never said a word ever since he was an orphan right after he was found by the police to the orphanage. The nuns never see him but they do get presents from sometimes. The Thin Man may be best remembered because of his attraction/fetish towards a woman's hair which he was shown sniffing and rubbing on his face in ecstasy on more than one occasion. During his first haircut, he ripped a hair bang out of the nun and sniffs on it. Ever since then, he has a fixation with ripping out women's hair and smelling it. He is the most recurring (and the most popular) character in the films, as he has appeared more than any other villain. In the sequel, he redeems himself from Dylan Sanders but is stabbed by Seamus O'Grady before falling from a roof, probably fatally injured. The Thin Man could however have survived because it then uses Seamus as a human shield when letters fall on them.
