Formerly crooked investor Warren "The Great White Shark" White, avoided prison time by pleading insanity and was sentenced to Arkham Asylum. There, he suffered great indignities and torture, including Killer Croc slicing a set of "gills" into the "prison fish"'s neck. White was assaulted and locked in a refrigeration unit by the villainess Jane Doe, who was attempting to claim his identity. His injuries, sustained by excessive frost bite, left White deformed: His skin turned a pale white, and the frostbite claimed his nose, lips, hair, and several of his fingers, which, along with his set of "gills" leave him very much resembling a great white shark. Driven partially mad, he now uses his business connections to serve as a liaison and fence for many of his fellow inmates.

One Year Later the Great White Shark has been using his mob connections (as well as the the assassin Tally Man) to kill those associated with the Penguin, as well as to frame the newly rehabilitated Harvey Dent for their murders. The Great White Shark remains in Arkham, directing these actions from within as an alibi. Batman has since confronted him, and has threatened to tell Dent, who had redisfigured his face and returned to crime, about the frame job, promising to let Two-Face have a shot at the Great White Shark when Two-Face is captured and returned to Arkham.
