King Charles is an incompetent black bear who wears a crown.
He once got a hot hand at Glasses’ dice table, winning the money from “the wrong people” (he won it from Glasses). He has already spent the money on buying his crown and his car (a 1965 Cadilac el Dorado red convertible) and so Glasses arranged for his to assist with the HoneyCon heist to pay back what he owed.
