Action Noticing a lot of plastic pollution in the Seine, Marinette, Adrien, and their friends decide to campaign against it. The source of their problem is Bertrand King, a plastic tycoon, who had introduced plastic hand fans across the world with the help of Gabriel and Mayor Bourgeois. After the latter two are convinced to reverse their stance, Bertrand is akumatized into the "King of Plastic", who has the Bee Miraculous' power of Action and can turn anything he touches into plastic. After his defeat, Marinette's anti-plastic movement grows worldwide.
