After Chloé sets off a false fire alarm forcing the entire student body to do chores as punishment, Adrien scolds Chloé telling her that she needs to be 'nicer' to people if she wants them to remain friends. Chloé's butler, Jean, has her host a party for everyone and encouraging her to what her old teddy bear would do. Confident, Hawk Moth sends an akuma beforehand. During the party, Chloé tries her best, but when seeing Adrien dancing with Marinette, Chloé loses her temper and Jean accidentally reveals her teddy bear, leading Chloé to embarrassment and to fire him. Feeling vengeful, Jean is then targeted by the akuma, and turns into Despair Bear, a doll-sized villain who has the ability to manipulate anyone he touches.
