Miraculous Ladybug Season 2 episode 24 Catalyst
After facing another supervillain late at night, Marinette and Adrien go home and fall asleep. However, they are soon awoken only seconds later and reminded that it’s Heroes’ Day: a day where every Parisian has to do a good deed in honor of their superheroes. Marinette panics since her time as Ladybug prevented her from preparing hers, but she is saved by Tom and Sabine, who give her a box of macarons to give to her classmates.
Meanwhile at the Agreste mansion, while getting ready for school, Adrien sees his father through his bedroom window staring at a stone statue of Emilie Agreste. As he goes downstairs, Nathalie tells Adrien that she booked the Chinese and fencing rooms for him as he requested and reminds him that he much also make an appearance at the Agreste Foundation’s Heroes Day Gala. After Adrien leaves for school with his bodyguard, Nathalie goes to talk to Gabriel and tells him that it’s time to implement his plan, pointing out how his target, Lila Rossi, has had months to brood her anger over Ladybug. It will be peaked now that everyone is celebrating her on Heroes Day. Gabriel asks Nathalie if she’s really okay with helping him, to which Nathalie says that she’ll always be there for Gabriel.
At school, Lila speaks to Miss Bustier’s class through a video chat. She tells them that she is in the country of Prince Ali (The Kingdom of Achu) and had been invited by him to his palace. Marinette, aware of Lila’s deceitful nature, attempts to expose her lies by pointing out that Prince Ali is in America, but Lila says that Prince Ali wasn’t actually with them. Marinette vows to herself that she’ll expose Lila’s lies one day, but Alya, who overhears, believes that Marinette is just jealous because Lila had once tried to date Adrien. When asked by Miss Bustier what she has prepared for Heroes’ Day, Lila says that she has received permission from other countries to work on a project to reduce pollution and is meeting with Prince Ali to get his approval. The class and Miss Bustier, excluding Marinette and Adrien, are amazed and thank her on behalf of planet Earth. She then claims that she has to go because it is getting late where she is. Once she hangs up, it is revealed that she actually still lives in Paris and is hiding in her room. When her mother comes in and asks who she was talking to, Lila says she was talking to her boyfriend, Adrien. Lila’s mother also asks her about the school, which Lila claims is closed from all the akuma attacks. Lila’s mother then receives a call from Mr. Damocles, but Lila convinces her not to answer it since he’s probably been akumatized. The two are then interrupted by the noise of the ongoing Heroes’ Day Parade, which irritates Lila.
Miss Bustier tells the class that even if they don’t have Prince Ali as a friend, there are other ways to do good deeds. Mr. Damocles bursts into the room dressed as The Owl and talks about how Ladybug and Cat Noir have saved Paris from Hawk Moth. He then asks everyone what heroic deeds they’re doing. Nino says that he will be playing music for the retirement home. Adrien says that he will give a Chinese lesson to his fencing class and a fencing lesson to his Chinese class. Alya says that she has met with the mayor to discuss building handicap facilities. Hearing everyone’s good deeds makes it hard for Marinette to admit that all she did was bring macarons for the class. Chloé mocks Marinette for doing so little, but Alya defends her by saying that it’s better than nothing. Angry that Alya would imply that she didn’t prepare anything, Chloé says that since she is a superhero, she is offering her autograph to anyone who wants one. However, Marinette still feels embarrassed by not having much done, so she tells the class that she is organizing a party for the whole school with countless amounts of pastries.
Once home, Marinette asks her father for help in making the treats, but he cannot since he has to finish baking a giant Ladybug cake for the mayor. Sabine advises Marinette to just be honest with her classmates, but Marinette decides to make the treats herself instead.
Nathalie and Gabriel wait inside the lair for the first part of their plan to unfold. In her room, Lila angrily scrolls through a bunch of news feeds about Ladybug until coming across an interview with Gabriel and Nadja Chamack. In it, Gabriel announces that he is funding a tribute to Ladybug due to her saving him and his son countless times. After he says that Volpina is a false hero in comparison to Ladybug, Lila becomes enraged and flings her laptop against the wall. With her negative emotions hitting their peak, Gabriel transforms into Hawk Moth and sends an akuma to Lila. It infects her wristbands and Hawk Moth offers her the power of illusion once more. Lila agrees, and she is transformed back into Volpina.
“Akumatized Ladybug” and “Cat Noir” are fighting, with the latter warning everyone to stay back from his possessed friend. The two of them fight briefly, with one of the news reporters recording the battle. “Akumatized Ladybug” tells “Cat Noir” to give his Miraculous to Hawk Moth, but “Cat Noir” tells her if Hawk Moth wants a ring he can make one himself. “Akumatized Ladybug” tells him that it is not nice to deny a request of from a friend. “Cat Noir” tells her that they won’t probably be friends again until she is deakumatized. “Akumatized Ladybug” traps “Cat Noir’s” hand in her yo-yo. Just then, “Cat Noir” summons his Cataclysm and attempts to use it on the yo-yo to stop her. However, “Ladybug” is too fast and pulls him towards herself, and she plants his hand on his own chest: “Cat Noir” disintegrates into black dust, which shocks everyone dearly. “Akumatized Ladybug” picks up Cat Noir’s ring and announces that she will give it to Hawk Moth.
With the people of Paris drowning in despair, Hawk Moth seizes his opportunity to continue the second part of the plan. He deakumatizes Lila and then creates another akuma in his lair for Nathalie. It infects her tablet and transforms her into Catalyst, a supervillain who has the ability to boost powers. Catalyst infuses Hawk Moth’s cane with energy, which transforms him into Scarlet Moth, allowing him to release as many akumas as he desires. With his boosted powers, Scarlet Moth sends a swarm of akumas all over the city.
