ALOPEX IRONGALL
The History Professor Who Makes His Own Lessons
Battle music:
- Alopex's boss battle would likely be a bullet hell battle, taking place in some kind of time vortex.
- His bullet patterns for "nonspell" segments of the battle would use fire-type bullets that spin around like the hands on a clock, but his "spell card" segments would probably evoke various historical events, potentially with the implication that they're ones that Alopex has influenced on his travels, be they intentional or otherwise, direct or indirect.
- Fitting his "professor" motif, he'd likely be either right at the start of the game or right at the climax (or maybe both?), serving as a sort of "final exam" to see whether you're ready to embark on the rest of your adventure/whether you've become strong enough to have a fighting chance against the final boss.
