Mandy

Mandy is a cynical and arrogant girl with blonde hair with a black hairband, black shoes, and a light pink dress with a yellow flower on it. Mandy, unlike Billy, is smart and loves absolute power, order, chaos, and control, which is something she uses to make Grim her obedient servant and slave. Billy and Mandy are best friends, although sometimes it is hard to tell. She almost never smiles, and denies it when she actually does. Her parents are also scared of her. Mandy usually gets what she wants and she does not hesitate to speak her mind
