Of course! And there are several r!charas created by non-mods. Off the top of my head, there’s Max, Chrys, and Luis. Many other characters that just kind of appeared from the TAU collective consciousness, like Toby, where someone comes up with a headcanon and someone else runs with it, etc. Hell, if you trace back RRR and Belle  to their origins, they started with an anonymous ask to the blog! It’s a pretty communal experience.

Anyway, there aren’t any hard and fast rules to making r!charas. Just try to stick to the hard rules of canon. For example: a human soul most likely isn’t going to reincarnate into a demon or generally anything but a human (with kitty!Mabel a rare exception). Physical traits don’t pass over, nor do abilities, memories (except very rarely) or powers. Things like that.

Creating an r!chara is always a tricky balance between making a distinct, new character and giving them traits that the “original incarnation”, so to speak, had so the shared soul between the two incarnations can be seen. But again, there’s no rules to that process! Sometimes a character is a lot like their preincarnation, and sometimes they share few traits at all. In strange cases like Toby, they’re total opposites! But we’d say the real rule is to have fun with it!
