What I have done is taken the Pokemon game title screen theme (specifically the one from Crystal) and arranged it for Drum Corps. After that, it goes into a percussion feature where the drumline has a drum break and the mallet percussion play the trainer battle theme from Red, Blue, & Yellow. After that, it goes back into a softer slow feel of the original theme leading up to an exciting ending.
Although, the cheap finale sounds are terrible. So here's another link to a GPO version.
