[@BangoSkank] I was going to ask about the manager, I think that's a good idea. Sort of a Gedo type of role where it's a former wrestler turned manager who still steps in the ring occasionally. And like you said, since Gerald Shaw is the major star, Mr. Watanabe could eat pins and it's not a big deal. 

And for the Muta character, I'd definitely rather they be a PC as opposed to an NPC since it's such a classic gimmick. My take on it was an enigmatic face-painted wrestler named Orochi (who sort of had a snake-themed vibe going on). He was silent of course, but had a manager/valet named Kasumi (a name that literally translates to "mist"). 

And as far as the men's vs women's divisions, I've given it some thought and I wonder if it's just easier to have everyone in the same division, as is the case with most e-feds you'll find online. It makes things easier when you have a smaller roster overall, and you can just focus on the characters above everything. Just treat it like a fighting videogame sort of, where it doesn't matter.
