A demon who changes into the form of a person that alredy exists and copies them in any aspect, personality, voice, and qualities... Sometimes, it does look a little off, though. Their voice is distorted, the more angry they get, the more distorted it is. They try to manipulate the people into letting them in or get their trust. Looking at them in their original form is lethal. Their original form is a black tall creature with sharp claws, with the only thing on their face being wide eyes.
