 The trauma from Ludo's childhood comes out when he fashions dolls in the likeness of his parents.After imagining them saying loving, supportive things for a while, the caricatures revert to memory and he compulsively puppets the abusive, denigrating personalities his parents actually have.Ludo Avarius (voiced by Alan Tudyk) is a major avarian from Mewni with a round head and a beak and wears a cap made out of the upper part of a creature's skull.
