Thomas Hearns (born October 18, 1958) is an American former professional boxer who competed from 1977 to 2006. Nicknamed the "Motor City Cobra", and more famously "The Hitman", Hearns' tall, slender build and oversized arms and shoulders allowed him to move up over fifty pounds in his career and become the first boxer in history to win world titles in five weight divisions: welterweight, light middleweight, middleweight, light heavyweight and super middleweight.
