9) Marvin Hagler/Marvelous Marvin Hagler
Marvin Hagler will go down in boxing history as one of the best ever, of that there is no doubt. Between 1980 and 1987, Hagler was the Undisputed World Middleweight Champion, and till date holds the highest KO (Knock Out) percentage at 78%.
But there was something that was annoying Hagler, and that was the commentators and network announcers not referring to him by his nickname “Marvelous”.
So, to solve this particular annoyance, Hagler decided to legally change his name to Marvelous Marvin Hagler in 1982.
