Thinking about it more, in addition to those Biigohs, we could also have a sort of "youkai-ish" Biigoh, but not like how we talked before where it's a gestalt warring states era, but one that has a lot more Rumiko elements, like Ranma 1/2, since, you know, "martial arts" as a theme, but we could still have this Biigoh be a shitty hanyou in the warring states era
