Chloé Bourgeois is Marinette's rival and a student in Miss Bustier's class at Collège Françoise Dupont. Her father, André Bourgeois, is the mayor of Paris. In "Antibug", after Ladybug ignores her suggestions on how to beat Vanisher and calls her a liar, she is infected with an akuma by Hawk Moth and becomes Antibug, an anti-Ladybug supervillain.
