I love most of these but one I don’t think anyone knows about is Bloody Roar on PS1. Typical fighter but each character could also transform into a different beast mode with a new move set. Tons of fun although I don’t think it’s aged well at all.
That was BR2. BR1 was kinda distinct because instead of the bat lady it had a heavyset middle-aged warthog woman - most anime-styled fighting games only include female characters for T&A (like the bat lady).
