Gym Leader Battle
Pokemon Red / Blue / Yellow
Although this one wasn't as popular as the 2009 Pokemon R/B/Y Trainer Battle, I like this one more.
I like the way I arranged this one. The intro is played note for note on 4 different instruments, first 2 guitars, then keyboard, then bass. Fun stuff. After that we get to the main part where the guitar and keys go at it back and forth, all throughout there is that fast little guitar lead in the background. The composer for Pokemon gets some sort of boner for crazy fast chromatic stuff, so this appears often throughout the song. I threw in a few metalcore-ish breakdowns as well.
The only thing keeping this from being excellent was the fact my mixes at this time sounded cheap. Other than that, this is a decent selection from the 2010 lineup.
