If you had to fight someone......

spitfire by prodigy...i'd walk up in slow motion with that song playing and look all badass...and then proceed to get beat to within an inch of my life.

The key to a really good entrance is that it is sudden and instantly recognisable. The better ones are more about the music than catchy lyrics, so don't go for something that you'd want to sing along to (few exceptions). With that said, it seems logical that I should go for the Chicken Dance.

Alternatively...
Def Leppard - Pour Some Sugar On Me
INXS - Guns in the Sky
Jurassic Park - Main Theme (for when I get up myself)
Los Lobos - La Bamba (for when I somehow turn Latino)
Kris Kross - Jump (for when I turn into a badass gangsta after tiring of my old routine)

Eye of the Tiger... Because I'm a cliché like that :P

What would your entrance music be? I'd have to go with the Star Wars Imperial March. I remember watching A New Hope and the scene when Darth Vader boards Princess Leia's ship, he walks down the hall like a bad mofo. I'd so want to emulate that.

Just to nitpick..."The Imperial March" does not play in A New Hope. That's a common misconception. But it is a cool tune and Vader is definitely worth emulating when "entering the ring".
