"SO in case you didn't notice in my last fight the UFC did NOT use my nickname when I fought. Turns out some gay ass wrestling federation threatened to sue them because they recently named one of their wrestlers The War Machine Rhino and trademarked the name. Too f*ckin' bad that I have been using this name for 6 years, have it tatted on my body and it is what my fans yell out when I'm fighting. If you know my personality then you know damn well I am not gonna let some faggot ass, FAKE wrestler steal MY name. SO 6 weeks ago I filed a change of name request and today I had court to make my name officially WAR MACHINE. lol. F*ckin' funny right? Didn't really wanna have to do it but I am sure as hell not lose MY nickname."
-- Former contestant on season six of The Ultimate Fighter (TUF) and current UFC fighter, Jon Koppenhaver, has legally changed his real name to his nickname, "War Machine." It's apparently legit. TNA is the professional wrestling entity that has trademarked that name for one of its stars simple known as, "Rhino." Koppenhaver, er, War Machine, must really, really, like his nickname.
