"A serial killer who terrorized London in the 19th century. He killed prostitute after prostitute in the slums of London, then mutilated their bodies. The media was quick to cover the murders, and the case was the talk of the town. Scotland Yard came up with a few suspects after a thorough investigation, but the case went unsolved. This unusual case still piques the imagination today, with aspiring detectives coming up with their own theories. Whether or not this Jack is the culprit remains a mystery. Perhaps the image of the murderer conjured up this demon."
He is one of the three titular Jack Brothers that make up the games playable cast alongside Jack Frost and Pyro Jack. In the North American release, he was renamed to Jack Skelton. Unlike his brothers, he lacks a ranged attack, but has one of the strongest attack stats in the game to compensate. His character-specific ending focuses on the enemies arguing after he escapes.
