As a child, Barton Mathis went on several 'hunting trips' with his father. During these hunts, he watched as his father killed people and then cannibalized them. He would also witness his father being shot down by a young cop named James Gordon. After spending only a year in foster care, Barton disappeared for years before he resurfaced as the criminal Dollmaker. His mask is partially made of skin from his deceased father. 
He later cut off then reattached the Joker's face.
