#1 Muhammad Ali
Arguably the greatest boxer in history, Muhammad Ali will always be a name held in great reverence.
Born Cassius Clay, Ali made his name in the boxing world, losing only 5 fights, and is also known for his work as a campaigner for equal rights for African-Americans
In wrestling, Ali was the guest referee for the main event of WrestleMania 1, which saw Hulk Hogan and 2014 Hall of Famer Mr. T, defeat Roddy Piper and Paul Orndorff.
