Faust: Love of the Damned

John Jaspers, an amnesiac wearing metal gauntlets with claw-like blades, kills multiple people before being detained by Lt. Dan Margolies. John's memory is recovered after Doctor Jade De Camp uses a death metal CD to drive him into a rage, revealing he had sold his soul to M to avenge the death of his girlfriend Blue. John, now transformed into the devil Faust, uses his supernatural powers to kill M's henchmen and protect Jade, but is ultimately defeated by M, only to later kill him when Jade breaks free from their contract.
