I dunno, probably Rejuvination - Funky Fly. Lara Emily (a poster on here) made me a theme song.
But if I were to use something else, it might be any of these:
James Brown - The Boss
Nas - Get Down
Lacuna Coil - Tight Rope (this would be a kick ass theme for just about anyone)
Children of Bodom - Triple Corpse Hammerblow
Children of Bodom - Black Widow
Children of Bodom - Hate Me!
Children of Bodom - Angels Don't Kill
Children of Bodom - Everytime I Die
Talib Kweli - Gun Music
Dilated Peoples ft Talib Kweli - Live On Stage (Remix)
Stratovarius - Destiny
Manowar - Brothers of Metal (check my sig
)
Pharoah Monch - Fuck You
Run DMC - Kings of Rock
