In different sports an athlete who wins five crowns, titles, medals, belts, or other distinctions is called a Quintuple Champion.
In boxing, a quintuple champion is a boxer who has won world titles in at least five different weight classes.
The first man in boxing to earn this distinction was Thomas Hearns on November 4, 1988.
He moved down in weight to net the Middleweight (160 lbs) crown and finally moved back in weight up to Super Middleweight (168 lbs) to become the first Quintuple Champion in the history of boxing.
Mick Doohan won five consecutive 500 cc World Championships starting in 1994.
