Gambol was Gotham City's African-American mob boss. His personality was very arrogant, impatient, tough, and confrontational. Although wealthy, Gambol consistently wore fancy suits and professional attire, as he dressed like a well-off businessman. He is an enemy of the Joker throughout the film, and he foolishly believes that he can beat him. He was used to being in charge and powerful. This, coupled with his arrogance, helps to lead to his ironic downfall.
