Great White Shark (Warren White) is a villain in Batman. He was a crooked financier who embezzled millions of dollars and had scored a legal victory when his insanity plea went through. But when he arrived at Arkham Asylum, he realized his mistake; driven insane by the other inmates, Mr. Freeze soon turned his skin to chalk white and left him without hair, nose or lips. Calling himself Great White Shark, Warren filled his teeth into points to better resemble his new alias.
Putting his financial skills to good use, he was a major player in Gotham City's underground crime scene, running a number of rackets from his cell in the asylum.
