Episode Title:
Reverser.
Episode Description:
A shy student named Marc is invited to the Art room. Marinette asks Marc if he could assist Nathaniel in script writing. She reads a fictional journal of Ladybug that Marc drops. Giving the journal to Nathaniel really inspires him and Marinette sets up a scenario where he can meet the author. However, he gets the wrong idea when seeing Marc, accuses him of trying to fool him, then tears the journal and leaves. The misunderstanding causes Marc to be akumatized by Hawk Moth, transforming him into "Reverser", a supervillain whose paper planes can alter people's personalities in the opposite direction. Reverser has Mr. Bourgeois direct outer space garbage dumps to descend towards Paris, and to make matters worse, he hits Ladybug and Cat Noir, making them clumsy and scared; forcing Nathaniel and Alix to help save them from further chaos.
