I'm not sure what would be my final battle theme, I guess it would depend on the mood.
Really.
For most cases, I guess "Hallowed be thy name"

would be a good choice.
"The La2t Frontiier" might also be neat, although short

For Ironic battles, "Always look on the bright side of life"
http://www.youtube.com/watch?v=WlBiLNN1NhQ
or maybe "Dance of death"
http://www.youtube.com/watch?v=MZDB0mAMkA4
or even: "Only the good die young"
http://www.youtube.com/watch?v=c9Gtsukhh8A
"perfect gentlemen"
http://www.youtube.com/watch?v=ZiKfmG0nW40&playnext=1&list=PLB92F606D97F5876F&index=12
If it's MY struggle.. I guess I'll go with either of those
"For the greater good of god"
http://www.youtube.com/watch?v=3lP8rbMpHx8
"No more lies"
http://www.youtube.com/watch?v=ihpxdZFV3Ck
"Rainmaker"

I CAN'T DECIDE!!!(oh well, I probably cheated by placing way more then one....Shuffle button?)
Edit: a lot a Dethklok might be good, like Dethharmonic. go forth and die or even black fire upon us
