Doppel

Doppel is a shapeshifter of unknown real name who serves as MON's infiltrator. Her usual appearance is a small girl with dark skin, very long light hair, and black sclera, but this is not her true form; Doppel herself suggests that a human mind could not handle seeing what she really looks like. Seemingly a natural trickster, she enjoys using her abilities for pranks and particularly likes targeting people she feels deserve them.
