Basically she is just like roy.she died and was brought back to life by a parasite :).hmm lets say she was thrown into a lake and couldn't swim ir something and since the parasites only live underwater(i might draw a picture of it)she was came back probably a year later when barely anybody remembered.she doesn't remember anything that happened beore she died but can only remember things like how to eat walk breathe talk and her name.when a parasite takes over a body it gives that body an ability.and with roy his ability is that he can't feel pain physically.with Nancy hmmmmm she can shapeshift!yes.she can shapeshift into anything.object,animals,maybe even ppl!but she can only look like them.she cant change her skin color so if she shapesshifts into roy or sherly or tiffany then she will look like them she will just be pink.also she can onnly turn into things she's seen before.so if she doesnt know what a lamp is she can't turn into one.umm she is still 20 but died when she was 19.uhhh ig thats it
