Candice's Father (only referred to as Daddy) is a very rare example of a character whose voice is heard, but is never actually seen. He seems to side with Chick Hicks, and his sole role is to upgrade antagonist Candice.
Cars: Race-O-Rama Edit
He was heard in the end scene for Candice's Glam Tour, after Candice loses to Lightning, she calls her father on the phone in the back of her hauler, which was parked there, saying that she wants new everything, and then he agrees to get what his daughter wants. Candice then drives off, presumably to meet up with him.
