Its maw is filled with various, sharp teeth, seeming to stem from SCP-087-B's face, a characteristic derived from A-246, the entity it is in place of. It has two, oval shaped eyes, with its pupils drastically smaller than its black sclera, similar to A-80's old jumpscare image. Generally the entities palette is white, encapsulated by a violet purple, with this hue additionally being emitted from the entity itself.
