Normally I'm not terribly keen on metal as a genre, but I particularly like this song, probably in part just because I have a special fondness for this tune, but also because it's extremely well done. I appreciate the sheer quantity of energy in this song, and the fact that you've managed to combine both heavy guitar and drums with the 8-bit sound such as at 2:08 without making it sound silly. Obviously, they are two very different instruments that might not combine easily, but not only have you managed to make the combination work well, you've made them jell perfectly.
Also, the Dragonite cry works very well in the two places where you've put it in.
Overall, an excellent battle theme.
