The French Miraculous superhero team is a superhero team of Miraculous holders in Paris, France. Their current purpose is to defeat Hawk Moth's akumatized villains, prevent him from taking the Ladybug Miraculous and Cat Miraculous, and possibly recovering the lost Miraculouses.
In "Ladybug & Cat Noir (Origins - Part 1)", when Master Wang Fu and Wayzz figured out that the Moth Miraculous was being used for evil, Fu decided that he would need help in stopping its user. To find suitable users, Fu went into the streets and tested people by pretending to be feeble and needing help. Marinette pulled him across the street and out of the way of a rushing vehicle, while Adrien handed him his cane and helped him stand up from the ground, despite the sacrifices both teenagers made to assist him. Afterwards, Wang sneaked the Ladybug Miraculous and Cat Miraculous in tiny chests into their rooms.
Adrien and Marinette opened the chests, unleashing the Miraculouses' kwamis. Tikki and Plagg explained their powers, Hawk Moth's akumatization, and the need to save Paris to Marinette and Adrien respectively. Adrien eagerly accepted the responsibility to become Cat Noir, while Marinette reluctantly transformed into Ladybug. The heroes met up while testing their new abilities, and both figured out how to stop Stoneheart, not without some mistakes and complications along the way. Ladybug gained confidence in herself, while Cat Noir became smitten with her. However, Ladybug forgot to purify the akuma, leading it to multiply and transform many people into frozen copies of Stoneheart. Crestfallen, Marinette decided she wasn't meant to be a superhero, taking off the Ladybug earrings.
Marinette attempted to give the Ladybug Miraculous to Alya at school by sneaking it into her bag in "Stoneheart (Origins - Part 2)", but she didn't discover it before rushing off to see the re-akumatized Stoneheart. Trying to get Alya's bag to her, Marinette witnessed Cat Noir being overtaken by the Stoneheart copies and Alya being pinned to a building by a thrown car. Desperate to save them, Marinette put the Ladybug Miraculous on again and transformed into Ladybug. She saved both Alya and Cat Noir, and she took responsibility for failing to stop Stoneheart when she was called out by Roger Raincomprix. Cat Noir cheered her up by reminding her that she had saved lives, but before more could be accomplished, an image of Hawk Moth appeared, comprised of akumas. Hawk Moth demanded for Ladybug and Cat Noir to give up, but Ladybug argued back about his villainous deeds and the heroes' intention to stop him. With Cat Noir's help, Ladybug purified all of the akumas, saved Ivan and Mylène, and returned Paris back to normal with Miraculous Ladybug. Ladybug and Cat Noir split ways, with the latter admitting he can't wait to see her again soon.
After their origins, the duo of Ladybug and Cat Noir continued to fight any akumatized villains Hawk Moth sent their way constantly by daily accidents to saddened moments to specific individual such as Chloé and even themselves accidentally, along with doing heroic acts outside of fighting like protecting the mayor's daughter. While Cat Noir developed romantic feelings for Ladybug, she only saw him as a friend, already having a crush in her civilian life. Some notable events include the temporary death of Cat Noir in "Timebreaker", Marinette almost having conflicts with Cat Noir and finding out about past Ladybug Miraculous holders in "The Pharaoh indirectly with Alya's help", and meeting Wang Fu as a healer for Tikki without finding out his role with the Miraculouses in "Princess Fragrance". During "Lady Wifi" and "Simon Says" there had been heavy suspicions about their secret identities along with almost losing their Miraculouses, but the team managed to surpass this events. Things began to change for the team in "Volpina" when Adrien unknowingly found the Miraculous spellbook in a safe in his father's atelier with Plagg's help. He took the book from the safe, and the book eventually ended up with Marinette and Tikki for the latter's concern. Taking the book to Wang Fu's massage shop, Marinette officially met Master Wang Fu.
In "The Collector", Marinette and Fu concluded that whoever previously had the book had to be Hawk Moth as it was stolen along with the Butterfly and Peacock Miraculouses during the destruction of the temple of the Order of the Guardians.
After wondering if it was Adrien, Marinette suspected Gabriel was the true culprit as he's an eccentric artist who never leaves his home. However, Gabriel threw them off by akumatizing himself, which the heroes and Wang didn't know was possible. Once she and Cat Noir defeated Gabriel's akumatized form, Marinette returned to book to Gabriel after Wang took pictures of it with his phone in order to rescinds Adrien from his grounding. Like the rest of the previous holders, Marinette received kwagatama from Tikki in her birthday in "Befana", symbolizing their friendship. Sometime afterwards, as mentioned in "Sapotis", Wang Fu teaches Marinette about the other Miraculouses and anything he learns from the spellbook.
In "Robostus", Ladybug and Cat Noir heard Robostus declare that he wanted their Miraculouses to grant his wish of being human, connecting that the ability to make a wish is also what Hawk Moth wants. Later, Marinette asked Wang Fu about it, who explained that the Ladybug Miraculous and Cat Miraculous together (along with a using a special invocation) can grant a person's wish and alter reality. However, in order to keep the universe in balance, there is a price to pay for each wish; for example, if Robostus had wished to be human, someone else would've lost their humanity in turn. With the new knowledge, Marinette determinedly vowed to keep her Miraculous and Cat Noir's Miraculous from ending up in anyone's hands, including Hawk Moth's.
During "Dark Owl" and "Glaciator", both heroes continued their duties outside of combat, such as helping the hero fan, Mr. Damocles of falling from a tree, and stopping a bus crashing, respectively. After Mr. Damocles was akumatized into "The Dark Owl" after he got humiliated being a superhero as Knightowl, he trapped Ladybug and Cat Noir in order to force them to hand over their Miraculouses. As part of Ladybug's plan to trick him in apparently giving their jewels, Ladybug and Cat Noir de-transformed while keeping their eyes closed. Tikki and Plagg discovered each other's partner's secret identity, but they kept quiet on their new knowledge.
When Ladybug and Cat Noir faced Sapotis, duplicating akumatized villains which caused chaos throughout Paris and were too many for the two heroes to defeat alone, Ladybug gets the idea from her Lucky Charm object, a teapot, to seek Wang Fu for help. When Wang realizes that Ladybug and Cat Noir need the help of another Miraculous holder to succeed, albeit reluctant about any Miraculouses being taken out in fear of a Miraculous falling into the wrong hands. He gave Marinette permission to choose a Miraculous, giving it to a trustworthy person, and have the person return it to her after the villain's defeat. After careful consideration, Marinette takes the Fox Miraculous, and as Ladybug, she gives it to Alya while making her promise to hand it back to her afterwards. Alya transforms into Rena Rouge, and with her assistance and quick-thinking despite being new at the job, the heroes stopped Sapotis. Although she initially struggles with not wanting to give up the Fox Miraculous, Alya returns it to Ladybug. Marinette returns the Miraculous to Wang, who congratulates her for making a wise choice. Meanwhile, Hawk Moth figures out that a guardian has to be in Paris like he predicted because of the Fox Miraculous' appearance.
Unknown to Adrien by studying both rings Gabriel believes that his son is Cat Noir in "Gorizilla" as Hawk Moth, he even akumatizes Adrien's bodyguard to prove his point. By having Wayhem, a fan act as his double, Adrien was able to fool him and keep his identity safe.
At an unknown time after the events of "The Collector", in the second issue, Wang Fu explained the origins of the kwamis and the Miraculouses to Marinette. Later that day, she and Cat Noir were summoned to New York City through a portal by Doorman. As detailed in the third issue, various superheroes requested their help in fighting a huge threat, the Trash Krakken. While reluctant with their leader Victory's plan, which involved catastrophic destruction followed by the Miraculous Ladybug fixing all of the damage, Ladybug and Cat Noir agreed to help. However, theorizing that a stuffed animal called Mr. Squid could be related to the monster, Ladybug decided to directly face the monster against orders, Cat Noir loyally following her. Knightowl, Sparrow, and Majestia, with persuasion, were willing to temporarily try the plan to snatch Mr. Squid from the Trash Krakken's body in the fourth issue. While Sparrow was caught in the Trash Krakken's body, Ladybug, Cat Noir, and Knightowl successfully took the toy. The Trash Krakken reverted back into a human man, and the toy was purified with Ladybug's yo-yo. With New York City saved, the duo and the other superheroes confirmed their alliance, and the duo returned to Paris through another portal.
Whenever they realize there are villain attacks happening, Marinette and Adrien transform with their kwamis and Miraculouses into their superhero personas. Both have enhanced physical abilities, such as strength, durability, and agility. While both are skilled fighters in their own rights, they have their unique knowledge and skills: Ladybug is very clever and quick at thinking up plans, able to figure out how to use her Lucky Charm object to benefit her situation. For his part, Cat Noir is skilled in fencing and understanding various languages, along with having calm observations and reactions in serious situations. Ladybug is the only hero able to purify akumas, but outside of occasions where Ladybug or Cat Noir have to battle villains on their own, they usually work best as a team by utilizing their strengths together.
