[@EchoWolff]: I'd rather there be no OCs of that nature in the RP, if possible. The only 'gray area' I can think of in this case is characters whose appearances are variable but whose personalities can be defined to some degree(e.g. Fire Emblem's Robin/Corrin, Mass Effect's Commander Shepard, and so on).

Again, if a choice is too nebulous, run it by me and I'll give it a check over (just so people don't commit on a form that I might take issue with).
