Another akumatized guy called Strikeback is destroying Paris, but it's later known that he's actually Hawkmoth's first illusion "also known as sentimonster, but here is called illusion".
Marinette goes to Felix's prom, trying to keep their relationship. Meanwhile, Hawkmoth learned already how to create illusions, so he creates an illusion of himself as Gabriel akumatized into The Collector.
Ladybug and Cat Noir fight The Collector until they realise he's Gabriel, so they try to make him reject his Akuma, but it will be hard when it's secretly right him behind this.
Ladybug suggests Luka "Viperion" and Alya "Volpina" to create a team with her and Cat Noir. Unfortunately, this breaks Cat Noir's plan of having a relationship with Ladybug.
Plane-shaped giant alien birds called "Birdvasion" attacks earth to find food source and bring it on their planet. All 4 team up and fight them. P.S. : Cat Noir's jealous on Viperion.
Ladybug and Cat Noir are fighting face to face with Hawkmoth for the first time. After Hawkmoth plays with Cat Noir's feelings, he gets mad and cataclysmes him on purpose.
After all, Cat Noir accepts to make a team with Viperion and Volpina. Hawkmoth is now weaker because of his cataclysm, but he uses so much power, that creates a giant Akuma, and sends it to fight the heroes.
Because of Gabriel's weakness, he can't create illusions or akumatize any longer. Nathalie, his housemaid, uses the peacock miraculous turning into Mayura. Now she is the one who can create illusions, and also find a cure for Gabriel.
