Ma Bagge is the mother of Eustace and Horst, and also one of the main supporting cast on the show. She despises Eustace's presence as well as Muriel's, but enjoys Courage's company, except when he is foiling her plans. She is bald and wears a red (sometimes pink) wig. She appears in an episode where she steals people's hair for profit and makes wigs. Ma lives in a trailer that is a quick walk away from the Bagge farmhouse. Ma Bagge is one of the primary antagonists of the show. She was voiced by the late Billie Lou Watt.
