Tex Colorado, the Arizona Assassion (the one from North Dakota ... South Dakota was his brother, from West Virginia)
Tommy preferred 'The Motor City Cobra' moniker. But either way, you know you have a special fighter, when they have two iconic nicknames. Another original one I liked was 'Six Heads' Lewis. I doubt he was the originator but Lenny 'Boom Boom' Mancini was the first I can think of to use the Moniker. 'Bam Bam' Hines rolls off the tongue. LaMotta's 'Bronx Bull' gets overshadowed. 'Bomber' Graham and Bruno worked. 'Razor' Ruddock deserves a nod.
Elmer 'Violent' Ray and 'Vicious' Victor Galindez sounded so badass. But comedically, I recall there was a fighter - I believe from Venezuela but could be wrong - named Jose 'The Threat' Baret who was making a lot of noise coming up until they prematurely matched him with Marlon Starling, who demolished him in about 3 rounds. After that fight they started calling him Jose 'Not Yet' Baret and Jose 'No Sweat' Baret. Too funny.
Curtis 'The Hatchetman' Sheppard. (That's a hitman or an IRS agent. Spooky either way) Homicide Hank (and Hammerin' Hank. AND Hurricane Hank for that matter). The Barbados Demon, The Boston Terror. ('nough said. Both describe little pockets of mass destruction.) Golden Boy (either of them. Catchy and g4y like Cindy Lauper.) 'Kitten' Hayward. (I mean KITTEN. And at his own volition. The twelve year old in you can't resist it.) Eric Crumble for real name. (Could've been a pastry chef but no. Had to tempt fate.) Also Will-o-the-wisp, Scotch Wop (nice sound), Babyfaced Assassin, Marvelous (also Cindy Lauperish), Manos de Piedra (and bowels of lava), El Flaco Explosivo, Nonpareil, El Feo (for the honesty), Sweet Pea (unlikely you'll find another one), The Upstate Onion Farmer (they ran out of ideas I guess), Joseph 'Sandy' Saddler (a more stripperish name like Crystal or Candy would've been better but that's good enough).
