Boxing Nicknames or Aliases that fitted the fighter to a tee?

Like Rocky " The Rock" Marciano, "Sugar" Ray Robinson and Leonard, " The Greatest" Muhammad Ali, Manny "Pacman" Pacquiao, "Sweet Pea" Pernell Whitaker, Thomas "The Hitman" Hearns, "Iron" Mike Tyson who I believed deserve and gave justice to their battle names. I don't think "Iron Boy" Ivan Calderon lived up to his nickname. So does "Pretty Boy" Floyd Mayweather.who is not pretty at all! Could you give me others you know who fit their boxing aliases to perfection as far as boxing style, performance and looks are concerned.
