Parent's Career Day at Marinette's school gets interrupted after Plagg accidentally steals Chloe's new bracelet, and everyone is a suspect. After Officer Roger refuses to arrest Marinette without proof, Chloe's father fires him. Roger soon seeks revenge as akumatized Rogercop.
- By-the-Book Cop: Roger is a positive example, refusing to break the law even when the mayor orders him to.
- Continuity Nod: Marinette's dad recalls a time when he had to bake a cake in the shape of the Eiffel Tower.
- Curb-Stomp Battle: Once again, the local police are no match for Cat Noir.
- Dramatic Irony: Neither Adrien nor Marinette knows how right Chat Noir is when he's teasing Ladybug:Chat Noir: I'd stick around, but then you'd see me without my mask, and you wouldn't be able to resist me.
- Everyone Is a Suspect: Invoked by Marinette to avoid being the only suspect. Her father calls her out on it.
- Flying Car: Roger's police car is affected by the akuma too, becoming a futuristic flying car and taking to the air to try and lose Cat Noir and Ladybug.
- Gullible Lemmings: The police go right along with Rogercop's obviously illegal takeover, and then follow his orders without question.
- Incredibly Obvious Bug: The tracking device that Rogercop attaches to the mayor's car is fairly small, but has a blinking light on it.
- No Badge? No Problem!: Rogercop enforces the law despite being fired. Of course, it's his own brand of justice.
- Pet the Dog: Plagg asks Adrien if he's okay after he learns that his father won't show up. The rest of the episode is a better example of how helpful he usually is.
- Police are Useless: The police just go along with a robot cop taking over the city, fighting Ladybug and Cat Noir on his orders.
- Rage Against the Legal System: Admittedly, Roger was only fired rather than wrongly imprisoned, but the general idea of the trope still applies.
- Rank Up: Officer Roger earns the rank of Lieutenant at the end of the episode.
- Robo Cam: Seen in shots from Rogercop's POV.
- Super Cop: Rogercop is a villainous and Knight Templar example.
- Ship Tease: While filming the class presentation, Nino briefly focuses on Marinette and winks at her. Doubles as Foreshadowing for a later episode.
