The Doppleganger

The majority of her background is fairly unknown, the basic premise of her is a little girl who is extremely shy and creates clay molds of people to hide behind and control, puppets of sorts. if she needs to she can focus more energy onto the puppet to make it look more accurate, She also gets the primary traits from the person she's trying to replicate by default, so she can conjure up a puppet and obtain these abilities even if the puppet has several deformities, although the puppets are relatively weak, considering they're made out of a clay like substance. Whether or not she's human is unconfirmed, however there is an argument to be made for "insidious entities"

Her appearance depicts a small girl in a dark dress, semi-short hair in the same dark color, and a small crown-like head piece with strange symbols. Despite her appearance depicting a young lost girl, it could be stated that she is much older than her appearance lets on. It is entirely that the primary appearance she dawns is just another way for her to hide herself from onlookers.
