The Wolfman was originally a man called Larry Talbot who was bitten by a werewolf and later transformed into a werewolf himself on the night of the fullmoon.
Upon his transformation into a werewolf Larry is very violent and spread terror in his home town of Blackmoor where he killed several townspeople without mercy. Each morning he would change back into a human and shocked at what he had done in his werewolf form. Later he is captured and placed in a asylum and is mocked by people and Doctors who came to watch him, Larry tries to warn them that he will become a werewolf as soon as the fullmoon comes out but they continue to mock him. Then as soon as the moon comes out he transforms into a werewolf and kills several of the people and Doctors in his way. In the end he is eventually shot by a silver bullet and dies in his human form.
