I love KH boss music. Battle music was the first type of music I started out with. I've always been fond of percussion as well, as the snare drum was the first instrument I ever learned, and I really liked how Shimomura uses it to her music's advantage when writing these orchestrations.
The battle music can sound totally different with the percussion removed.
This is a newer version of "Light's Triumph" which when I wrote it a few years back, I had always imagined it would fit as a sort of mini boss theme kinda like Rowdy Rumble in KH2. After seeing this new AMAZING trailer, I thought this could fit as a Toy Story specific boss theme. Especially in the Galaxy Toys area
