The only thing here that has given me a genuine pause is her origins since in Halloween, you only come into existence via
two ways. IDK if you have gotten GM clearance on the origins, in which case this is irrelevant, but, your origins posts seem to contradict shop canon. She's patchwork but...not an undead. I'm...hesitant to really identify her as monster or undead since 99.9% of patchworks ARE undead. And you could make the case that by using the skin of dead plant matter she herself is also undead, having been made from dead organic matter, FEAR infused or not.
All this aside, I am concerned with her goals to make a baby when...in shop you only get kids in one of two ways. You don't...physically make them? The story is certainly creative, but I would contact a GM about it and get it cleared unless you have already done so, in which I'd make a point to quote the approval so you don't get people like me asking.
