French Miraculous superhero team

The  is a superhero team of Miraculous holders in Paris, France. Their current purpose is to defeat Hawk Moth's akumatized villains and prevent him for taking the Ladybug Miraculous and Cat Miraculous.

Television series
In "Ladybug & Cat Noir (Origins - Part 1)", when Master 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, Master Fu 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, and the need to save Paris to Marinette and Adrien respectively. Adrien eagerly accepted the responsibility to become Cat Noir, and 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 Alya didn't discover it before she rushed 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 Cat Noir, love-struck, 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, along with doing heroic acts outside of fighting the villains. While Cat Noir developed romantic feelings for Ladybug, Ladybug only saw him as a friend and had a crush on a teenager in her civilian life, Adrien. Some notable events include Marinette finding out about past Ladybug Miraculous holders in "The Pharaoh" and meeting Master Fu without finding out his role with the Miraculouses in "Princess Fragrance".

Things began to change for the team in "Volpina" when Adrien unknowingly found the Miraculous spellbook in a safe in his father's atelier. Adrien took the book from the safe, and the book eventually ended up with Marinette and Tikki. Taking the book to Master Fu's massage shop, Marinette officially met Master Fu.

Miraculous Adventures
At an unknown time after the events of "The Collector", in the second issue, 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 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 and Sparrow, 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.

System
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. Cat Noir is skilled in fencing and understanding various languages, due to his education in his civilian life, and he has useful 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.

After Fu translates some of the spellbook, Ladybug and Cat Noir gain new superpowers related to particular situations, like ice-skating and underwater modes in dealing with particular villains. Also, for times where they need more support and assistance for defeating a villain, they have part-time superhero team members.
