Miraculous Tales of Ladybug and Cat Noir Season 5: to Be Released in Late 2024 on Disney Channel

During a school field trip, Ladybug and Cat Noir meet the American superheroes, whom they have to save from an akumatized super-villain. They will also discover that Miraculous exist in the United States, too.

Marinette helps Alya babysit the latter's twin sisters, Ella and Etta. When they keep staying up and refuse to go to bed, Alya forbids them from going to the amusement park the next day and confiscates one of their hats. The twins, sad over the fact they now can't go the amusement park and have to listen to their older sister's orders, are fighting over the other hat, then Hawk Moth akumatizes them both into "Sapotis", a pair of small but totally unpredictable monsters that multiply and cause havoc. When Ladybug and Cat Noir are overwhelmed by the creatures, Ladybug is prompted by her Lucky Charm to visit Master Fu, who loans her the Fox Miraculous. Ladybug gives the Miraculous to Alya, who, with the command of Trixx the kwami, transforms into the fox-themed superheroine, "Rena Rouge". After the three heroes overcome the Sapotis menace, Alya reluctantly returns the Fox Miraculous to Ladybug and keeps the details of her adventure a secret. However, a new superhero made Hawk Moth realize that there are more Miraculouses in Paris, as well as their Guardian.

Marinette, Alya and her other friends go to eat some ice cream together at a cart owned by André, a famous ice cream maker in Paris. According to a legend, the couple who eats an ice cream at André's place will love each other forever! Marinette hopes that Adrien will be there, but he did not come. For a good reason: he transformed into Cat Noir to prepare a candlelight dinner for Ladybug. Disappointed in Adrien's absence, Marinette refuses to eat the ice cream André gave her. Depressed over the failed romance, André becomes akumatized by Hawk Moth and shapes into "Glaciator", a giant ice cream snowman who solidifies 'single people' into ice cream and they start to melt! Ladybug and Cat Noir must not get cold feet if they want to stop him. In the midst, Marinette comes to know Cat Noir's genuine and sensitive side.

Principal Damocles starts cosplaying his favorite hero, Knightowl, and tries to act like him in real life as well. However, he becomes the laughing stock of Paris when his heroic exploits go horribly wrong and accidentally reveals his identity from his heroes. Humiliated, Damocles is akumatized by Hawk Moth and transforms into "Dark Owl", who has real superhero powers. Dark Owl manages to trap Ladybug and Cat Noir in a chamber where they will drown unless they hand over their Miraculouses, which would also mean revealing to each other their true identities. With Ladybug not ready to know that yet, they de-transform with their eyes closed, unaware that Tikki and Plagg see not only each other but also learn the identity of the other's owner. The two kwamis feed each other, so Marinette and Adrien can regain their powers, while they trick Dark Owl and Hawk Moth by giving them fake Miraculouses made out of salt dough. Ladybug and Cat Noir eventually defeat the owl-themed supervillain, and then help Mr. Damocles to become a superhero on a smaller scale by doing good deeds.

Today is a great day for Marinette: she and her friends, Mylène, Rose, Juleka, Alix and, of course, Alya, have come up with a flawless plan to help Marinette propose a romantic stroll to Adrien. But nothing is going as planned and Adrien's bodyguard, annoyed by the girls, becomes Hawk Moth's target. However, while the latter tries to akumatize him, the bodyguard calms down when he sees Adrien. Instead, Hawk Moth has to deal with something unexpected: the akuma goes and transforms a young baby child, who is upset and crying, turns into "Gigantitan", a fifty-foot (disobedient) giant baby, who would stop at nothing for a lollipop!

When Max builds Markov, a miniature robot capable of real human emotions, he is hesitant to even reveal him. After helping prevent a computer virus from wiping the school's servers, Principal Damocles instead confiscates Markov, thinking that he's a toy. Separated from his friend, Markov even becomes akumatized, and Hawk Moth converts him into "Robostus", a techno-threat capable of giving life to mechanical devices. When Hawk Moth tells Robostus to bring him the Miraculouses, he mistakenly informs him of their power to grant wishes. Robostus takes Max with him in his new mega-sized body to the stadium, where he ambushes Ladybug and Cat Noir. When Robostus is about to obtain the heroic duo's Miraculouses, he intends to take them for himself to gain mortality; only for Max, wanting his friend back, to free Ladybug and Cat Noir, who capture and de-evilize Markov. Marinette later asks Master Fu, who elaborates the Miraculouses' ability to grant wishes. Due to the universe needing to maintain balance who ever is granted a wish, someone else must lose the very thing wished for. Marinette promises Fu to not allow this, and continue guarding her own Miraculous.

On the fencing court, Marinette has hopes of joining to impress Adrien. Armand assigns the new recruits to pair with the experienced ones. A new student, Kagami Tsurugi, the daughter of a famous fencer, moved in Paris and challenges Adrien to show everyone she's the best fencer. After the duel, Marinette; the referee, unsure how the battle ended, due to Kagami chasing Adrien around and battling roughly, declares Adrien the winner, much to Kagami's dismay and humiliation, causing her to depart from the school. Hawk Moth akumatizes Kagami, and turns her into "Riposte", a silver armor samurai villain with the power to slice and cut anything in half with one armed saber. To make matters worse, Adrien hurts his leg and has to cover it while helping Ladybug as Cat Noir at the same time without revealing his identity.

Marinette is excited because today is her birthday. Not only that, but her grandmother, Gina Dupain, is also visiting. Despite being excited to visit Marinette, Gina is surprised to see how much Marinette has grown up, but is saddened when Marinette does mostly new things. While hanging out, Marinette heads to where her friends planned her surprise party and ditches Gina. Thinking she was rejected, Gina is akumatized by Hawk Moth, turning her into "Befana", a motorcycle baddie with the ability to turn people who do bad things into coal and those who do good into angels, who become her servants, with a gun filled with candy she wanted to give Marinette.

Marinette has to babysit Manon, but realizes Ladybug has to interview for a television show Face to Face, so she invites Alya over and excuses herself to help her parents downstairs. Realizing she needs higher television ratings, host Nadja resorts to asking about Ladybug and Cat Noir's romantic relationship, which causes Ladybug to storm off, dragging Cat Noir along with her. The studio is dissatisfied and cancels Nadja's show. Laid off, Nadja gets akumatized, and Hawk Moth turns her into "Prime Queen", a haughty reporter whose ability to teleport through television screens and posters; she creates a show in order to capture the two heroes, going to great lengths to prove that Ladybug and Cat Noir is truly in love.

Chloé's butler, Jean, has her host a party for everyone and encouraging her to what her old teddy bear would do. Confident, Hawk Moth sends an akuma beforehand. During the party, Chloé tries her best, but when seeing Adrien dancing with Marinette, Chloé loses her temper and Jean accidentally reveals her teddy bear to everyone, leading Chloé to embarrassment and fires him in the kitchen. Feeling vengeful, Jean is then targeted by the akuma, and turns into "Despair Bear", a doll-sized villain who has the ability to manipulate anyone he touches inside a small teddy bear in which he controls.

Marinette is formally introduced to Master Fu, whom she knew as Tikki's healer, learning that the man is the last Miraculous Guardian due to a past mistake he made that destroyed his temple with the Butterfly and Peacock Miraculouses lost in the chaos. Fu reveals the book Marinette brought to be a spell book covering Miraculouses, suspecting its owner could be Hawk Moth, with Marinette fearing Adrien could be the masked figure. But she learns from her classmates that the book belonged to Adrien's father Gabriel, who prevent Adrien from going to school for losing the book. Marinette heads to the Agreste estate as Ladybug, finding out that Gabriel had been akumatized into "The Collector", a supervillain with the ability of trapping anything that touches the pages of his blank sketchbook. After Ladybug and Cat Noir eventually defeat and restore Gabriel, Marinette and Fu concludes that he cannot be Hawk Moth. Fu copies the book's contents onto a smartphone before Marinette returns it to Gabriel, admitting that she was the one who held the book, not Adrien. Gabriel reveals that he obtained the book while visiting Tibet and that it is a memento of his wife, rescinding Adrien's grounding as he returns to school to the joy of his classmates. But Gabriel is revealed to have copied the book along with being Hawk Moth, having akumatized himself as a ploy to cover his tracks.

As Nino completes his challenge, the next contestant, a hypnotist named Jacques Grimeau, is given the challenge to hypnotize Adrien's father Gabriel Agreste. However, Gabriel refuses to participate in the challenge, causing Jacques to fail. Angry that he was not given the chance to at least try, Jacques becomes influenced by Hawk Moth and turns into Jackady, an extravagant villain who can hypnotize someone by throwing playing cards at them.

The next morning, Marinette brings her earrings to school and slips them into Alya's bag, still upset for forgetting to purify the akuma and convinced Alya would be a better Ladybug.

Questioned by his classmates, nobody believes Ivan when he claims not to remember anything; he storms off in anger when Chloé mocks him. Marinette comforts Ivan; encouraged by her, Ivan sings Mylène a love song, but accidentally scares her off. Ivan turns into Stone Heart again with Hawk Moth's akuma, and takes control of his duplicates around Paris, which come to life.

Adrien rushes to stop Stone Heart as Alya takes chase to film the battle; Marinette runs after her, wanting to pass her the earrings. Stone Heart's duplicates catch Cat Noir as he saves Alya from being crushed by a flying car. Marinette has no choice but to transform; breaking Cat Noir out, they rush to Trocadéro. Ladybug catches Chloé when Stone Heart throws her towards Pont d'Iéna from the Eiffel Tower's lower deck. A swarm of akumas fly out of Stone Heart's mouth, forming Hawk Moth's face, who declares that Paris will be spared if Ladybug and Cat Noir's Miraculouses are surrendered. Ladybug refuses, stating that Hawk Moth is the one at wrong, and cleanses the akuma cloud. Hawk Moth orders Stone Heart to take their Miraculouses; he and his duplicates begin to climb the Eiffel Tower. Ladybug climbs to the top of the tower, using her yo-yo to make Mylène kiss Stone Heart's chest; surprised, he drops the paper ball the akuma is in. Ladybug crushes it and cleanses the akuma. After her magic cleans up the damage, Ladybug passes Mylène Ivan's song lyrics. Mylène hugs Ivan; Ladybug and Cat Noir run off to transform back. Later, Adrien's father allows him to go to school while Marinette stands up to Chloé, taking the latter's seat. That evening after school, it's raining outside; Adrien hands Marinette his umbrella, and the two share an intimate moment before parting ways. Master Fu and Wayzz watch from afar, satisfied with their decision to give them the Miraculouses.

It's Marinette's first day of school. Hawk Moth captures a butterfly kwami named Nooroo and forces his allegiance. Hawk Moth's butterfly brooch allows him to give someone a superpower they desire and to make that person obey his will. He plans on using his new powers for evil purposes, intending to create villains to lure the heroes out to fight them, so he can steal their Miraculouses and gain absolute power. Master Fu, a 186-year-old Chinese man,is notified of Hawk Moth's capture of Nooroo through Wayzz, his own kwami, a turtle. However, he is too old to fight anymore, so he pretends to be a weak old man, travelling Paris to find suitable charges for the Black Cat and Ladybug Miraculouses, hoping they can stop Hawk Moth and free Nooroo. He is helped by Marinette when he crosses a road and is almost hit by a car, and Adrien when he pretends to have fallen down. As school is dismissed, Ivan and Kim, two of Marinette's classmates, have a dispute, after Kim sends Ivan an offensive message on paper. Upset and angry, Ivan becomes Hawk Moth's first ever victim, turning into Stone Heart, a giant rock monster who grows in size after taking damage. Master Fu learns of this, and has no choice but to quickly deploy both the Black Cat and Ladybug Miraculouses, sending them to Adrien and Marinette. Marinette and Adrien both find a small box in their room, and after touching them, are quickly greeted by Tikki and Plagg. Both kwamis give their charges a quick explanation; soon Marinette and Adrien transform into Ladybug and Cat Noir and rush to stop Stone Heart. Despite their lack of experience and poor fighting skills, they manage to defeat Stone Heart and free the akuma. However, Ladybug forgets to purify the akuma after the fight; it flies off, duplicating itself and infecting many people, turning them into immobilised Stone Hearts. The episode ends as Marinette learns of her fatal mistake, and in her despair, thinking that she can't do her job as Ladybug, removes her earrings and puts them away under her dressing table, causing Tikki to disappear.

Believing that she'll always stay cursed and unnoticed, Juleka becomes influenced by Hawk Moth and turns into Reflekta, a flamboyant villain who can zap people into making them look exactly like her.

Marinette is babysitting Manon. They are playing with hand-crafted dolls that Marinette made herself, Marinette playing as Ladybug and Cat Noir and Manon playing as Lady Wifi, Rogercop and Evillustrator.

However, Nadja Chamack, Manon's mother, doesn't want her to borrow it, as she complains that Manon already has too many toys; they get into a dispute, resulting in the Ladybug doll getting torn. Despite that, Manon still wants to borrow the Ladybug doll, so she asks Marinette for it behind her mother's back.
