depends on if i'm going full Scuff Aura or not; maybe it could be a buildup of glitching along the course of the game...

so in that case, i'd guess for my themes, my regular boss theme would be Fight Back A Chap from Galaxian3: Project Dragoon

because it's just SO good and gives that feeling of "you've got this!!! i believe in you!!!" which, i wouldn't wanna be a MALEVOLENT boss, y'know? i'd wanna cheer my opponent on as they kick my ass lmao

and my final boss theme when i'm at my most corrupted would be Squeaked Hours from Armored Core: Last Raven
