Announcement:
Don't be afraid to make the spirits come from generic enemies like I did with Fiora! They do not have to be from the same franchise. There are mechon led by Metal Face, demons/vampires led by Dracula, and darknuts that operate on their own, but may end up in a villain's army. Get creative, include whatever generic enemies you want.
Again, the generic enemies do not have to house spirits from their franchise. I could have stuck Fiora in a darknut for example.
