Christophe's Mom appeared in South Park: Bigger, Longer & Uncut. After her son says bad things about God, she grounds him, suggesting she is Christian. She and Christophe speak with French accents, suggesting that she and her son are from France.
Christophe's Mom has long, straight brown hair with a hairband. She wears a white collared shirt under a blue and white sweater, with a long navy blue skirt. She also wears a white headband and gold earrings.
She does not seem to have a very good relationship with her son, and according to Christophe, she had attemped to kill him by stabbing him in the heart with a clothes hanger. She does show strength over her son. Christophe appears to be intimidated by her, still listening to her. Christophe's Mother does not agree or allow her son's misotheism, and grounds him for saying such things.
