Hammerhead was originally a small-time gunman employed by one of the "families" of the criminal organization known as the Maggia. Hammerhead's real name is unknown even to himself. Years ago, he was found beaten, disfigured, and delirious with pain in an alley in New York City's Bowery by Jonas Harrow, a surgeon who had lost his medical license due to his illegal experiments. Apparently, Hammerhead had suffered a certain degree of brain damage and he was now an amnesiac. However, he was obsessed with the last thing he saw before losing consciousness: a poster in the alley for a movie called The Al Capone Mob. Seeing the opportunity both to save this man's life and to redeem his reputation, Harrow operated on the gunman for three days, replacing much of his shattered skull with a strong steel alloy. During this time the gunman dreamed about the images in the poster he had seen. Upon recovering, the gunman decided to become a gang leader in the style of Capone and other mobsters of the 1920s. He even dressed as if he were living in that decade. Ultimately the gunman, who became known as Hammerhead, took over a gang from the Maggia family of organized crime.
