'Scrap Iron' Johnson 'Pinky' Thomas 'Boom Boom' Mancini Bash Ali (Not really a nickname, but awesome nonetheless)
"Buster" Douglas "Iron" Mike Tyson "the truth" Williams" is my favorite. "Money" Mayweather is tge worst. "Pretty boy" suited him better,it would have been a better persona IMO.
Among my favorites: "Sugar Baby" Rojas Andrew "Six Heads" Lewis "The Whitechapel Whirlwind" Jackie Fields "Merciless" Ray Mercer Least favorite: Carl "Squirrel" Daniels
