Biography
In 2002, Tony Zucco helped murder John and Mary Grayson on the orders of the Maroni crime family, who were performing at Haly's Circus. Years later, Tony was arrested on charges of racketeering and tax evasion, but Gotham Police Department let him walk away relatively free, because he could help them arrest members of the Maroni crime family. Detective Dick Grayson was unhappy of this decision and decided to attack him as Robin. During the attack, Tony was killed by Maroni's thugs for snitching.
