Hands of Stone The Hitman Sugar Michael "Second to" Nunn Homicide Hank Iran "The Blade" Barkley Lights Out The first ones that come to mind.
"Iron" Mike Tyson Simple, easy to remember, accurately describes his physique and chin, and vaguely patriotic in a time when people felt better about America.
The Perpetual Motion Machine, which is a name used for the great Harry Greb. It wasn't his main nickname, but I like it a lot. There are others that I really like, but you guys have pretty much covered them.
Jim 'Bang Bang Bang Bang' Lampley Larry 'I'd Kick Your Ass' Merchant Harold 'Associated Rules of Boxing...Jim!' Lederman Joe 'The Terminator' Calzaghe Manny 'The Terminator' Pacquaio David 'The Terminator' Tua
This one was great too. The best ones are the ones where people can call you out on the street by, and Iron Mike fits just as well
That's not really a nickname though. "Ghost" is a nickname but "the Ghost with a Hammer in his Hand" sounds like the name of a Scooby Doo episode.
My favorite is Manny "The Destroyer" Pacquiao. I dont like "Pacman" so much. I also like Juan Manuel "Dinamita" Marquez.
