During Career Day in Marinette's class, Chloé loses an expensive bracelet (to Plagg) and accuses Marinette of stealing it, as she had just slipped over Chloé's bag. Chloé persuades her father, Mr. Bourgeois, to order Officer Roger to handcuff Marinette and search her belongings. Roger, however, refuses, saying that he cannot do that, unless there is evidence Marinette stole Chloé's bracelet, as it is against the law. As a result, Mr. Bourgeois, who is the Mayor of Paris, fires Roger. Infuriated at the mayor over this issue, Roger becomes akumatized by Hawk Moth and changes into "Rogercop", a RoboCop-themed villain who wants to bring justice to those who break the law. Not to mention that his police car turns into a futuristic flying car.
