Thomas Hearns (born October 18, 1958) is an American former professional boxer. Nicknamed the "Motor City Cobra" and more famously "The Hitman," Hearns' slender build allowed him to move up over fifty pounds in his career and he became the first boxer in history to win world titles in four divisions. He would also become the first fighter in history to win five world titles in five different divisions. Hearns was named fighter of the year by The Ring magazine in 1980 and 1984, the latter following his one punch knockout of Roberto Durán. Hearns was known as a devastating puncher throughout his career, even at Cruiserweight even though he had climbed up five weight classes.
