Once upright, they have a long slender humonoid body with roten skin, a slender torso, long legs, with the chest as the head, long arms and tounge sprouting from the chest, the chest rimm lined with needle like teeth. they will begin to aggressively pursue the user. Mimic is fast, tough, and deal high damage; they can easily kill the unprepared user.
