Their current purpose is to defeat Hawk Moth and his Akumatized villains and Mayura and her Sentimonsters, to prevent them from taking the Ladybug Miraculous and the Cat Miraculous. The heroes also seek to recover the Butterfly Miraculous and the Peacock Miraculous.
In "Ladybug & Cat Noir", when Master Wang Fu and Wayzz figured out that the Butterfly Miraculous was being used for evil, he decided that he would need help in stopping its user. To find suitable users, he 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 respective 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", 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 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 continued to fight any civilians that Hawk Moth akumatizes into villains by exploiting the negative emotions caused by specific individuals 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 and a partner, due to her 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 conquer these 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 was eventually stolen by Marinette and Tikki for the latter's concern. Taking the book to Wang Fu's massage shop, Marinette officially met Master Wang Fu, the last guardian of the Miraculouses.The Collector", Marinette and Fu concluded that whoever was in possession of 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 and after learning that he owned the book. 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 rescind Adrien from his grounding. Like the rest of the previous holders, Marinette received a kwagatama from Tikki on her birthday in "Befana", symbolizing their friendship. Sometime afterwards, as mentioned in "Sapotis", Wang Fu teaches Marinette about the other Miraculouses and everything he learned from the spellbook.
In "Robostus", Ladybug and Cat Noir heard Robostus declare that he wanted their Miraculouses to grant his wish of being human, and they later realized 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 "The Dark Owl", both heroes continued their duties outside of combat, such as helping the hero fan, Mr. Damocles from falling from a tree. However, in an attempt to make his dream come true Mr. Damocles was eventually akumatized into Dark Owl after he got humiliated. As Dark Owl, he trapped Ladybug and Cat Noir in order to force them to hand over their Miraculouses. Ladybug tricked him by apparently giving their jewels, and as part of this plan, 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.
Sometime later, during "Glaciator", both Marinette and Cat Noir both admit to each other that they have relationship problems. When the two heroes meet again, this time with Marinette as Ladybug, Cat Noir treated her coldly but later forgave her afterwards. Once the mission was over, Ladybug said that she was in love with someone else but she considered him a close friend and a partner. As for Marinette, she discovers that the hero's feelings for her alter ego is very real and yet they remain hopeful of each other's love.
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 she 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, 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 is initially reluctant to give up the 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.
Unbeknownst to Adrien, by studying Cat Noir's picture, Gabriel believes that his son is Cat Noir in "Gorizilla" and even akumatizes Adrien's bodyguard to investigate. By having Wayhem, a fan, act as his double, Adrien was able to fool him and keep his identity safe.
In "Frightningale" and "Troublemaker", Marinette faced a similar problem when she accepted Clara's offer to play to her alter ego in Clara's video almost revealing herself until Chloé cancelled the shoot and when Troublemaker took one of Ladybug's earrings almost revealing herself to Cat Noir until she retrieved her earring.
During the events of "Syren", Cat Noir and Ladybug were able to use the other transformation abilities of their kwamis through the Miraculous spellbook to access Aqua Mode for the first time. Cat Noir also struggled with Ladybug who was hiding secrets from him, but after Adrien and Wang Fu officially meet he thanks her for keeping her promise. Gabriel also became more determined to find the guardian.
In "Anansi", as Ladybug and Cat Noir fought against Anansi, a spider supervillain who kidnapped Alya. But found out that she was too strong for them to handle alone with help from Ladybug's Lucky Charm object, which is a candle. She sought out Master Fu for help while Nino held off Anansi. Arriving at his shop, Marinette explained the situation as before he allowed her Marinette to pick a Miraculous along with a trusted ally. Knowing they needed the help of a protective one, she chose Master Wang's Turtle Miraculous and knew of the right person to give it to. As Ladybug, she gave it to Nino under the condition that it must be returned after Anansi's defeat. After Nino transforms into Carapace, with his Shell-ter power the trio was able to save Alya and defeat Anansi. After the mission, Nino returned the Turtle Miraculous to Ladybug and she returned it to Master Wang. However, Hawk Moth notices that the heroes are increasing in allies but has something more sinister planned for them.
In "Sandboy", The kwamis in the Miracle Box attempt to contact Nooroo on his birthday, but instead contact Hawk Moth, so now he knows the existence of the other kwamis and seeks to enslave them all. More information about the kwamis is revealed. For example, the active kwamis bring gifts of all kinds from their owner's home to share with the inactive kwamis, and that all kwamis are put under a magic spell that prevent them from saying their wielder's real names to other kwamis.
During Fashion Week in "Style Queen", Chloé's mom Audrey Bourgeois makes an appearance for the show meanwhile Gabriel Agreste is below his mansion talking to someone which is revealed to be his wife who has an unspecified condition, and is the reason he wants the Miraculouses in the first place. As the show started, Audrey was akumatized into Style Queen, Hawk Moth's masterpiece. To make matters worse, Adrien becomes the villainess' first victim, leaving Ladybug to fight on her own. When she tells Master Fu what happened, Marinette is greeted by Plagg, who has already told him.
Plagg offered to help her, but he said it was out of the question and allowed Marinette to pick a Miraculous, along with a trusted ally. Returning to the Eiffel Tower, Ladybug finds Alya and offers her the Bee Miraculous, but was attacked before she could use it. She was on her own and cornered until Plagg arrived and saved her with Cataclysm, (which reveals that kwamis can use their owner's abilities) leading to Style Queen's defeat and Hawk Moth losing hope. Meanwhile back at the fashion show, Tikki reminded Marinette of the Bee Miraculous and realized it's missing, but unbeknownst to her it was found by Chloé who opens it and is greeted by Pollen.
During the events of "Queen Wasp", Gabriel loses hope to the point where he relinquishes Nooroo and appears at the fashion show to embrace his son. As the show closed he and Adrien commended Marinette for derby hat design which impressed Audrey that she gave her the opportunity to come to New York. But Chloé was so angry and desperate to prove herself to her mother she unveils the Bee Miraculous and transforms into Queen Bee in front of everyone. Continuing to do so Chloé creates a fake emergency by using her powers to cause a speeding train. After being saved by the duo Ladybug demanded that she return the jewel but things get worse when Hawk Moth is renewed with hope and akumatizes her. The duo was able to deakumatize Chloé, now calm, they told her that the Bee Miraculous must be returned but she begged them for another chance. That's when they explained that everyone makes mistakes and it's important to fix them with that in mind Chloé returned the jewel and apologized to her idols. Meanwhile Marinette turns down Audrey's offer deciding to stay with her friends and family and helps Chloé make things up with her mother.
In "Malediktator", after everyone tells Chloé off about not being a hero she gets so angry and leaves for New York. But when André becomes akumatized into Malediktator a commanding supervillain, Chloé begins to realize her mistake and to make matters worse Cat Noir falls under the villain's control. Knowing she needed help Ladybug sought out Master Fu and chose the Bee Miraculous again this time knowing how to use it. After finding Chloé the heroine helped her come clean with her mistake and encouraged her to fix it now accepting full responsibility Chloé was given the Bee Miraculous. As Queen Bee, Chloé followed Ladybug's lead with her Venom power and Cat Noir's help they were able to stop Malediktator and save the city. This time not disobeying her idols, Chloé returned the Bee Miraculous willingly earning her teammate's recognition.
Ladybug and Cat Noir continued their duties outside of combat in "Frozer". However, they began to question their relationship, thinking they can only be just friends and nothing more, and seek help from Luka and Kagami. When dealing with Frozer in their new Ice Mode, the two went their separate ways but realized they work best as a team bringing their ideas together.
On Heroes' Day in "Catalyst", Hawk Moth commences his biggest plan yet through the help of Volpina he makes everyone vulnerable to akumatization and by turning Nathalie into Catalyst to amplify his powers Hawk Moth becomes Scarlet Moth. Using his increased powers, he reakumatized almost all the villains the heroes had ever faced, creating an army. Meanwhile Cat Noir and Ladybug summoned their allies to fight him.
In the second part of the season finale, despite Rena Rouge's, Carapace's, and Queen Bee's best efforts, they were akumatized into scarlet versions of themselves and turned against Ladybug and Cat Noir. But with help from the people of Paris, the duo was able to hold them off and square off against Scarlet Moth. By destroying his cane, they were able to deakumatize everyone, including their allies. Backing their archenemy into a corner, they were about to take his Miraculous until a new Miraculous wielder named Mayura entered the scene, leading to Hawk Moth escaping and the heroes suspecting he has the Peacock Miraculous wielder by his side. Nonetheless, the team rebels in their victory but knows the fight isn't over.
The duo continues their fight against Hawk Moth, however Lila makes her return and tries to win Adrien's affections as well at war with Marinette. In "Weredad", when Marinette believes that Cat Noir was going to discover her identity as Ladybug. She tells the hero she loves him however, during a brunch date he tells Marinette that he has feelings for Ladybug. With that Marinette was very happy but her convincing act lead to her father Tom's akumatization after a sky high battle, Cat Noir explains that he thought Marinette was one of his fans. When she accepts the hero's feelings for Ladybug they continue being friends.
And yet, little by little Gabriel gains more clues to finding the guardian in "Backwarder" when he akumatizes Master Fu's friend Marianne Lenoir. He learns that the guardian has been hiding under a false name, though he doesn’t know what it is.
With their memories restored and upon seeing the picture Marinette becomes shocked that she kissed Cat Noir while Adrien remains hopeful of his love with Ladybug and yet Hawk Moth has also discovered about their love for each other.
During "Silencer", Marinette discovers that Luka has developed feelings for her. And like him Kagami has developed feelings for Adrien in "Oni-Chan". After that Adrien warned Lila that they would no longer be friends if she harms his loved ones. But unknown to Ladybug and Cat Noir, that while seeing Lila's actions Hawk Moth as Gabriel struck an alliance seeing her as an good ally.
Rena Rouge, Carapace, and Queen Bee continue to help Ladybug and Cat Noir fight against Hawk Moth and Mayura in "Miraculer". Aware that their enemies know Chloé’s identity Ladybug has been hesitant on giving the Bee Miraculous to her out of fear of her and her loved ones being in danger. However, Hawk Moth and Mayura know this and use this to their advantage, using Lila Rossi's manipulation. After Miraculer's defeat, Ladybug finally explains to Chloé as to why she's been inactive recently. Chloé, albeit slowly, comes to an understanding and returns the jewel, but remains hopeful they'll call on her again. However, she stops worshiping Ladybug and views her as any other person. Hawk Moth also remains hopeful that they would get Chloé on their side someday.
During Adrien's trip to the Musée Grévin wax museum with his friends in "The Puppeteer 2", he received a mixed up message from Nino; thinking that Marinette hated him. Meanwhile Marinette had trouble keeping her cool when Alya left her alone, not wanting to lose her friendship Adrien tried to find a way to make her more comfortable but he froze. When he heard her say all those things about him, Adrien unfroze but upset Marinette and apologized. Then asked if she was for real about what she said but retorted saying she wasn't. Afterwards, having a moment alone they apologized for what happened and continued to be friends but Marinette was downhearted when Adrien admits that he had a crush on another girl but was encouraged by Tikki not to give up on him.
During "Stormy Weather 2", everyone laments on how much they've change through the powers of the Miraculous jewels and their feelings too.
During "Timetagger", it's revealed that in the future Ladybug and Cat Noir are still fighting akumatized villains who are now controlled by a new Butterfly Miraculous holder. It's also revealed they had assemble a superhero team that includes a future Alix Kubdel who holds the Rabbit Miraculous, using it to turn into Bunnyx.
During the fight against the titular villain in "Ikari Gozen", Ladybug temporarily lends the Dragon Miraculous to Kagami Tsurugi when she is taken prisoner by her akumatized mother. With it, Kagami becomes Ryuko and uses her power over certain elements to help Ladybug and Cat Noir defeat Ikari Gozen. However, because Hawk Moth got to know her civilian identity when she was freed, Ladybug, after having the Dragon Miraculous returned from Kagami, tells her she won't be able to give her back the Miraculous because of the risk of putting her love ones in danger. As Marinette and Kagami spend Friendship Day together, she starts to see another side to her due to her mother's strict upbringing Kagami doesn't have any friends but has a strong desire to make them. Despite losing the contest the two have a better understanding of each other.
"Reflekdoll" and the remaining episodes held many surprises for the heroes starting that they not only had to fight against Hawk Moth's akumatized villain Reflekta, but also a sentimonster created by his ally Mayura. However, that wasn't their only problem due to the destruction caused by Reflekdoll it led to the duo jewels becoming swapped. Despite walking a mile in each other's shoes as Lady Noir and Mister Bug they defeated them (unknown that Peacock Miraculous was damaged). Thanks to the experience Ladybug and Cat Noir have a better understanding of each other.
In "Desperada", two heroes come to the rescue for the price of one seeing the titular villain as a formidable opponent the Snake Miraculous' power of Second Chance was needed. However, due to Marinette having a "troubled heart", as Ladybug she picked Adrien to wield the jewel and due to him wanting to impress his crush as Aspik, it led to the heroine being captured several times over until he couldn't bare it anymore. Relinquishing the Snake Miraculous, Adrien informed her of what's been happening for the past few months. When Ladybug had no idea who else could use the Snake Miraculous that's when Adrien recommended Luka, with him becoming the cool, calm and focused Viperion. By observing Desperada and using the power of Second Chance to save his allies, the duo followed his lead in defeating her. Even though, Adrien didn't make a good impression as Aspik he decided to stick with what he's good at being Ladybug's partner as Cat Noir. As for Marinette, one day she'd have to choose between which boy she truly loved.
In "Startrain", due to battling constant villains by Hawk Moth, Adrien and Marinette were exhausted and ready for a vacation (but took the Horse Miraculous in tow in case trouble came.) And trouble it did, Max's Mother was akumatized into Startrain taking everyone on board the train to space. But knowing they'd need extra help Ladybug gave the Horse Miraculous to Max who became their new ally Pegasus and with his powers of teleportation the trio were able to take the train back down to earth.
By the time of "Party Crasher", even Ladybug and Cat Noir's team of five wasn't enough to stop the titular villain and they were all captured. Until Kim is chosen by Master Fu to become the holder of the Monkey Miraculous, known as King Monkey and rescued his teammates.
"Ladybug" turns into one of critical points for the team, through Lila's deception and lies, Marinette ends up getting expelled from school as well as almost akumatized into giving Hawk Moth her earrings (but was unknowingly saved by Nathalie). However, knowing that Lila was behind this Adrien told her of his earlier warning and convinced her to tell another lie that would prove Marinette's innocence letting her be reinstated in school. Meanwhile, Cat Noir and Ladybug begin to learn more about the Peacock Miraculous understanding that sentimonsters are more than just simply creatures. But that they also have their own will and feelings especially the elaborate ones like the heroine's sentimonster doppelganger. As well as how cruel the powers of the jewels can be when used for evil fearing that Mayura's power is more dangerous than Hawk Moth's. And yet, the continued use of the damaged Peacock Miraculous causes Nathalie to get sick ending her time as Mayura for now.
Plagg's obsession with cheese causes one of the biggest problems for the duo yet in "Kwamibuster". He and Tikki are spotted by Ms. Mendeleiev who wishes to prove their existence but it leads to her akumatization as the titular villain. As well as to Ladybug and Cat Noir believing that they may know each other in civilian form. During the confrontation the heroes lose their kwamis, in order to save Tikki, Marinette pulls off her greatest feat yet by becoming Multimouse with Mouse Miraculous and fusing the powers of the other Miraculouses. She was able to save her Kwami and the heroes were able protect their identities. However, upon seeing the power of the kwamis Hawk Moth's lust and desire for power continues grow.
In "Feast", Master Fu's mistake is fully revealed when he comes across a sentimonster he created long ago that he thought was gone. When he was very young he had no interest in being a guardian and was angry that he'd have to give up his normal life. During one of his training sessions Wang grew hungry and used the Peacock Miraculous to create a companion to get him food. But the creature Wang created wasn't only fueled by his hunger but also his anger at the Miraculous which resulted in him losing control of the creature and it destroying the temple, swallowing the guardians and the remaining Miraculouses. So he tried to escape his creation in doing so, Wang lost the Peacock and Butterfly Miraculouses and Miraculous spellbook.
Knowing that Hawk Moth and his partner Mayura would bring his creation back to life and hunt him or anyone with a Miraculous down. Refusing to let Marinette and Adrien suffer the same fate he took their jewels and tried to leave Paris and yet seeing his disciples stand up to the creature even without their powers. They showed Wang why he chose them, seeing their bravery he followed their example and stood up to his creation at the cost of revealing his identity to Hawk Moth. Knowing what needed to be done he returned the heroes jewels and by diving into the belly of the beast they destroyed the creature. With Feast destroyed, the Order of the Guardians was restored with Wang being eternally grateful towards Ladybug and Cat Noir freeing him from his burden of the past.
After seeing her actions, Wang calls Marinette a full fledged Ladybug and begins her training to become the new guardian. With his shop no longer safe, Wang decided to keep a low profile but refused to leave Paris until Hawk Moth was stopped. Assuring Marinette and Adrien that he'd always be there for them when they need him. However, now that Gabriel knew the identity of the Guardian, he started to find a way to put it to use.
"Felix", "Cat Blanc" and the Season finale, involves both loves and losses for everyone. As Adrien and his father celebrate the year anniversary of Emilie's "departure" they are greeted by family Adrien's aunt Amilie and his cousin Felix. However, due to Felix's mischief tension is caused between Marinette's friends who sent a video package but was answered with a nasty note but duo the managed to save Felix and make up with Adrien thanking his friends for their support.
The duo and Hawk Moth make their greatest mistakes, for Ladybug by not leaving Adrien's room quick enough, she unknowingly led him to figuring out her identity leading to an alternate future. With Bunnyx's help Ladybug was led to said future where she was surprised to find her partner akumatized into Cat Blanc and wanting her earrings to activate the ultimate wishing power. And yet even more so that he knew her identity with Bunnyx viewing the past she sees that despite the two ending up together Gabriel threatened to break them up so he could have another villain. Refusing to let Marinette go and seeing an akuma head towards her, Adrien transformed revealing himself to his love and unknowingly his greatest enemy.
Wanting to use this his advantage, even being cornered in his secret place, Hawk Moth unveiled his identity and purpose to the heroes. Causing his own son's greatest breakdown so close his goal Gabriel akumatized him but with Adrien so hurt and confused he caused his own demise as well as everyone on the planet. Meanwhile in the future Ladybug manages to save her partner and by fixing her mistake she changed the future, before Bunnyx leaves she revealed that her leader picked her was because she knew how to keep secrets. After facing everything she experienced Ladybug went off to enjoy a peaceful moment with Cat Noir.
Through "Battle of the Miraculous", everyone experience losses in their lives, upon seeing Adrien and Kagami get along so well Marinette decides to give up her romantic pursuit of him. Leading to her making a broken hearted decesion by going to Master Fu as Ladybug not only by taking the Dragon Miraculous, she unknowningly led Hawk Moth and Mayura right to him being captured and them obtaining the miracle box. After the mission, seeing that she put Master Fu in danger Marinette breaks down in front Luka about the stress of being her alter ego.
Seeing that Ladybug chose Ryuko over her and thanks to Hawk Moth's manpulation Chloe betrayed the team by turning into Miracle Queen putting their teammates in danger. Thankfully, to their aqua powers Ladybug and Cat Noir managed to avoid the wasps upon reuniting the duo discovered that the situation up top seeing that their enemies had their allies, Master Fu and the miracle box. Ladybug breaks down again in front of Cat Noir about this being her fault but hero comforts her knowing that everyone makes mistakes and that it's important to fix them making her extremely greatful to have him by her side. With her confidence restore the duo enacts a plan to save everyone and with the powers of Dragon Bug and Snake Noir they managed to save their allies and deakumatize Chloe.
Shocked by her actions, Ladybug tried to remind Chloe that Hawk Moth was their enemy but Chloe retorted that she was fed up with being overlooked by heroine despite her attempts to help. Wanting her revenge Chloe dared to use the remaining jewels against her former idol but the kwamis refused to help. Still under the power of protection, Wang Fu encouraged his disciples to continue on and passes his role as Guardian to Ladybug with her owning the Miracle Box. With the knowledge he planned to take from the former guardian and the box lost Hawk Moth and Mayura make their escape. After Chloe's failed escape attempt she told Ladybug off and that they are no longer friends. Due to her terrible actions, the heroine takes the Bee Miraculous from Chloe banishing her from the team.
What the duo also discovers is that due to Master Fu passing his role Marinette because of the Guardian's Code all of his memory about the Miraculous was erased and couldn't be restored. However, it wasn't a total lost for villains either by obtaining Master Fu's tablet of the decoded spellbook Gabriel was able to fix the Peacock Miraculous. Marinette takes Master Fu to Marianne at the train station despite with his memory erased he felt like he knew her forever and the two leave Paris. Meanwhile Marinette finds a note from her former master about understanding of experiencing losses in life, moving on and with more to come.
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.
After Wang 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.
For times where they need more support and assistance for defeating a villain, they have part-time superhero team members. One of them is Rena Rouge, who proved to have remarkable resourcefulness and cunning thinking. Then there is Carapace, who proved to have considerably combat skills and exceptional bravery. Another one is Queen Bee, who isn't impressed by people in power and, despite her obnoxious personality, has proven that she can be a very good teammate. Viperion who gives his teammates another chance, Pegasus who is fast and King Monkey who is a quick learner and brave.
Ryuko who has power over the elements and is an amazing sword fighter. In the future the heroes will also receive help from Bunnyx, a hero whose Miraculous power is to travel through time. She is called as a last resort, when all the other superheroes of the team fail to defeat the villain, as meddling with time is dangerous.
The two main members of the team, Ladybug and Cat Noir, aka Marinette Dupain-Cheng and Adrien Agreste, decided from the outset, by mutual agreement, to keep their respective civilian identities secret, even from each other.
Even the temporary Miraculous heroes they call for help try to respect this rule, with only Ladybug and (usually) Cat Noir as the only heroes in the team who know their secret identities.
However, there have been a few exceptions:
- Since "Queen Wasp", Queen Bee, aka Chloé Bourgeois, is the only hero whose civilian identity is in the public domain, having transformed in front of the cameras to show everyone (but specifically her mother) her value. Despite the recklessness of her actions, Ladybug, who was in a desperate moment and despite understandable doubts, chose to give her a second chance, and since then Queen Bee has helped the team for some important missions, only to be suspended by Ladybug due to her public civilian identity.
- In "Catalyst", Rena Rouge and Carapace, aka Alya Césaire and Nino Lahiffe, get to know each other's secret identities. While at first Alya had suspicions about Nino, the latter had no suspicion about the former, but in the Heroes' Day, Ladybug, who was in an emergency situation and didn't have a good justification in mind to separate the couple, was forced to ask both temporary heroes on the spot for help, revealing to each other the other's secret identity. Since then, she has made the two heroes swear to not reveal each other's civilian identities to anyone.
- In "Desperada", after a failed attempt to woo Ladybug with the Snake Miraculous, Adrien suggests that Luka Couffaine wields it. Since nobody besides Wang was aware that Cat Noir and Adrien are the same person, from Ladybug's and Luka's points of view, Adrien is just another temporary Miraculous holder, but who is aware that Luka is the new holder of the Snake Miraculous.
- In "Startrain", when Ladybug chose to give the Horse Miraculous to Max Kanté, besides her and Cat Noir, even Markov, Max's robot, was present at that time; it is very likely that Markov will keep the secret to protect Max.
- In "Ikari Gozen", Hawk Moth learns that Kagami Tsurugi is Ryuko after she is able to free herself from her akumatized mother's prison. Because of that, Ladybug tells her she may not give her back the Miraculous as it may put Kagami's loved ones in danger. Despite that, in "Heart Hunter", Ladybug asked again for her help, to secretly prevent her from dating Adrien at that time.
- In "Kwamibuster", when Plagg's gluttony nearly gets Ladybug's secret identity exposed to Cat Noir, Marinette takes up the Mouse Miraculous as Multimouse to defeat Kwamibuster. Afterwards, she deliberately outs herself as Multimouse to Cat Noir and uses the Fox Miraculous to trick him into thinking she and Ladybug are two separate individuals.
Ladybug, who is usually the one who recruits new heroes, knows all their civilian identities, as well as Master Wang Fu. Instead, while Cat Noir unquestionably knows the civilian identities of Queen Bee, Bunnyx, Ryuko, Viperion and Pegasus, and even though several important pieces of information have been revealed to him after having officially met Master Fu, it's still ambiguous if he knows the secret identities of Rena Rouge, Carapace and King Monkey, since Ladybug often sends him to re-recruit Queen Bee, who does not have a secret identity.
The situation, however, changed dramatically in "Miracle Queen"; the titular villain, aka Chloé, who allied herself with Hawk Moth and Mayura, took control over all Paris and commanded all the Miraculous holders to come to her, allowing Hawk Moth, Mayura and Chloé to learn the secret identities of Rena Rouge, Pegasus, Viperion, King Monkey, Carapace and Ryuko (Ladybug and Cat Noir escaped being affected by her powers, while Alix Kubdel, future Rabbit Miraculous holder, has not used yet her Miraculous in the present).
In order to save the other Miraculouses, and prevent Hawk Moth from extracting valuable informations from him, Master Fu definitively renounced his position as Guardian and Miraculous holder, and officially made Ladybug the new Guardian, at the expense, however, of his own memories of everything concerning the Miraculouses, including the secret identities of the heroes.
Later, because of Chloé's despicable actions, Ladybug seized the Bee Miraculous from her and definitively ousted her from the team.

- Aside from the kwamis of the superheroes, and Nooroo and Duusu who are captured by Hawk Moth, the kwamis in the Miracle Box are trying to help the team and save Nooroo, as shown in "Sandboy". The same team-up happened at Marinette's side to save Tikki and Plagg in Kwamibuster.
- Volpina — An akumatized villain who tricked Ladybug and Cat Noir into thinking she was the real Fox Miraculous holder and a superhero. With the use of her illusions, she made it look like she saved Paris from a meteorite and requested their help in stopping Hawk Moth, who appeared to be teleporting throughout Paris' rooftops. Cat Noir accepts her warmly, but Ladybug was suspicious and jealous of her. Once Volpina revealed herself to be an enemy accidentally, Ladybug and Cat Noir turned against her to revert her back into Lila.

After the villains' defeats though, the team doesn't hold anything against the victims, even calming down from the stress of being a victim.

When she is deakumatized, Chloé tries to use all the other Miraculouses, but her lack of knowledge prevents her from doing it. When Ladybug becomes the new Guardian of the Miracle Box, she is able to recover it and the Miraculouses from Chloé who then declares to Ladybug she's no longer her fan.
