Before Season 1
Adrien was home-schooled for his entire life. He lived in the Agreste mansion with his mother and father. At this time, his only friend was Chloé Bourgeois. His mother went missing within nine months before Adrien was allowed to go to school. This changed his father, making him more distant. Adrien started modeling in order to get closer to him.
In "Ladybug & Cat Noir", Adrien ran away from home and tried to go to school against his father's orders. He almost made it inside, but was followed by Nathalie and his bodyguard. He pleaded with them to let him go to school. Before he could go in, he saw an old man struggling to get up from the sidewalk, with his cane out of reach. Adrien handed the man his cane and was forced to return home. Nathalie was home-schooling him when Gabriel scolded him for leaving the safety of the mansion.
Upset, Adrien ran to his room but feeling the ground shake, he ran outside seeing Stoneheart throw a van at Agent Roger, and turned on the news in his room to learn more. Then, noticed a black box on his coffee table. Opening it, a flash of light entered the room and he met Plagg, After chasing him around his room, he put on the Cat Miraculous and transformed into a superhero. Eager, Adrien didn't listen to all of Plagg's instructions and left his room, jumping with his baton across Paris.
Getting the hang of walking on his baton, Adrien fell off when Ladybug fell from the sky and crashed into him. Once untangled, he introduced himself as Cat Noir and ran off to fight Stoneheart while his partner followed. At the Parc des Princes, Cat Noir stopped Stoneheart from attacking Kim, saved Alya from being hurt but misused Cataclysm on a soccer goal. Ladybug and Cat Noir took down Stoneheart and turned him back into Ivan. He returned to his house before he detransformed. Adrien tried feeding Plagg food his personal chef provided, but Plagg only accepted Camembert, much to his annoyance. That wasn't the only thing that brought him down: because Ladybug didn't capture the akuma, it multiplied and affected innocent Parisian citizens, turning them into Stonehearts. Even worse, Cat Noir couldn't repair the damage nor capture the akuma leaving him thinking.
In "Stoneheart", the next day, Adrien snuck out of the house again, complaining about Plagg's Camembert addiction, and made it to school before Nathalie could catch him. Chloé led him around the school and signed autographs for the people who asked. When Chloé put gum on Marinette's seat, he tried to remove it, but Marinette was mad and made him stop. Nino, seeing Adrien's predicament, decided to become his friend.
When Stoneheart busted down Miss Bustier's classroom's door and took Chloé and Mylène captive, Adrien ran from the room and transformed into Cat Noir. He hit Stoneheart and caused him to grow. Stoneheart called on his minions and they attacked the hero, letting the original Stoneheart walk away. When one of them threw a car at Alya, Cat Noir he threw his staff at it, keeping it from killing her however, this led to him being captured. Until Ladybug freed him when she returned his staff. They went after the original Stoneheart who was on the Eiffel Tower.
Ladybug didn't feel like she could succeed in taking down Stoneheart; since she failed once and the police didn't trust her but Cat Noir encouraged her to try again. When Hawk Moth told him to give up his Miraculous, he saw Ladybug step up and capture all the akumas creating his face. Then heard the promised that they would defend Paris and keep them safe. It was in that moment that Cat Noir decided that he loved the girl under the mask. He followed Ladybug up the Eiffel Tower to free Mylène and fought off the other Stonehearts while she figured out what to do with her Lucky Charm. When Ladybug made Stoneheart drop his akumatized object, Cat Noir threw it up to her so that she could free the akuma. He used Cataclysm so that he could catch Ivan. After all the damage was fixed he couldn't wait to see Ladybug again and leaves.
The next day, Adrien went to school with permission from his father. He apologized to Marinette for the gum incident and explained he was only trying to help her. Happy that he was forgiven and made a new friend, he went home.
In "The Bubbler", it was Adrien's birthday. He wanted to have a birthday party, but his father wouldn't let him. Nino tried to convince Gabriel to give Adrien one, but he failed and was banished from the Agreste mansion. After lunch, he went outside the mansion to find all of his classmates gathered in the courtyard and an akumatized Nino hovering above everyone on a bubble. Adrien ran inside to transform, but was convinced by Plagg to enjoy the party.
He listened to Plagg's advice and joined the party. At first, Adrien didn't notice how miserable everyone else was, but when Ladybug showed up, he ran of to transform. Cat Noir fought with her against Bubbler, but ended up surrounded with red bubbles and then captured by them. He demanded Bubbler bring the adults back, but that only angered him; they were sent skyward. Cat Noir used Cataclysm to escape from the bubble, threw his baton at the Eiffel Tower and let Ladybug swing them back to the ground. They returned to the Agreste mansion, but it was too late; the students were sent skyward. He and Ladybug chased Bubbler up the Eiffel Tower and distracted him with a broken air vent until Ladybug captured his akuma.
Back at the Agreste mansion, Adrien opened the gift Marinette left, believing it to be from his father. He wore the scarf to school the next day, very happy with the results.
In Mr. Pigeon", Adrien was in a fashion design competition as one of the prizes; he would model the hat that won the competition. He saw Marinette's designs and was excited for her work.

Before he could land a hit on him, he was thrown into a sarcophagus. The Pharaoh escaped with Alya while Ladybug freed Cat Noir.

Leaving the hotel Cat Noir exclaimed that it was going to be hard fighting someone they couldn't see and gleefully gave Ladybug a rose. But seeing the heroine's hair moving strangely the duo quickly got into a defensive stance; in the midst of fighting Vanisher Cat Noir heard from Chloé that Sabrina's akuma was in the brooch. After Sabrina was deakumatized he saw that she was right and asked why Ladybug didn't believe her and took his leave with her.
Soon after that he saw Chloé get akumatizied into Antibug, needing to buy time for Ladybug, Cat Noir fought against her but ended tied up to his staff and used as bait to lure her out. During Antibug's taunting he was asked to work with her but refused to work with a mere copycat saying he and Ladybug were a team hoping the real one would show up soon. Unknown to him, Cat Noir felt someone giving him a hand quickly assumed it was his partner (actually Marinette in civilian form) and was set free. With Ladybug back in action and a bag of marbles they were able to defeat Antibug, then Adrien went to school the next day.
In "Volpina", Adrien was secretly watching his father who was curious about what he was hiding in his safe. After Plagg opened the door Adrien saw a book (which is the miraculous spellbook.) Upon reading he also sees a picture Hawk Moth, but quickly leaves for school taking it with him. While there he comes across a girl named Lila who tries to tell him that she is a Miraculous wielder too. But through a harsh scalding from Ladybug, he found that Lila's stories weren't true at all and leads her to getting akumatizied into Volpina. At one point Adrien tries to talk Lila out of causing trouble but when it doesn't he transform into Cat Noir.
On the Eiffel Tower, he sees Volpina daring to drop 'Adrien' off the tower, but knowing it was an illusion Cat Noir showed Ladybug it wasn't really his alter ego but throwing his staff. The duo defeats Volpina, he hears his partner's attempt to apologize to Lila but she rejected it. Using his regular voice and keeping his bathroom door closed he convinced Ladybug that was ok. But Adrien noticed that his father's book was missing and asked Plagg if he moved it but the kwami said no. Leaving him worried that if he doesn't find it soon he'll have something scarier to deal with than Hawk Moth's anger.
In "Santa Claws", Adrien was decorating a Christmas tree in the foyer hoping his father would join him too since his mother wasn't here. Seeing that he wouldn't Adrien went back to his room in anger believing his father cared about himself deciding to hate the holiday he transformed into Cat Noir leaving his room. As he leaped through the city, Cat Noir sang about being a lonely cat of the night because everyone else got be with their families but him. The hero got so angry to the point where he dared to used his Cataclysm on a Christmas tree but was stopped by memory of his mother and used it on a Gabriel Brand Ad pillar instead.
Then he began to lament that he didn't wanted to be alone and that tomorrow would be a new day with that Adrien detransformed and yet noticed Plagg exhausted cold and hungry. Picking him up, he apologized for his actions but didn't have any food for him, remembering Marinette's gift he opened it to find a hat and found her to so nice. Placing his kwami inside he wished Plagg a "Merry Christmas" then with help from Santa Claus the two are brought back home. Arriving there he comes across Ladybug who was convinced there was a villain around but tried to convince her that it wasn't Santa Claus.
Afterwards he sees that Ladybug's mistake led to Santa Claus being akumatized for real and they transformed again. Along with her they chased Santa Claws through the Paris streets using a box the duo manages to grab Santa Claws' hat, purify the akuma and save the holiday.
In "The Collector", Adrien was asked by his father why he took the book. He answers saying he wanted to know what Gabriel was hiding behind the portrait. Disappointed by his actions, he said he'd get him another copy however was informed that it was one of a kind and the source of his inspiration. As a result, he was banned from returning to school and that he would continue homeschooling with Nathalie and was disappointed. Later, Adrien was playing pool, contemplating how to get his father's book back so he could go back to school.
Then heard his father's destructive tantrum and rushed downstairs to see what the commotion was. Just as he reached the door to his father's atelier, Nathalie stopped him, being told his father was very busy. Then, reminded that he was supposed to be practicing his piano. Knowing his dad wouldn't forgive him unless he got the book back, he transformed into Cat Noir to find it. When he was about to leave, he saw a message sent by Ladybug that said she knew who Hawkmoth was. Arriving, he was told by Ladybug that she believed it was Gabriel Agreste leaving him shocked and asking for proof. Ladybug answered by saying she couldn't tell him the proof, but showed him evidence that supported her claims.
When they arrived at the Agreste mansion, Cat Noir saw how destructive Gabriel's tantrum was. Then, they went up to look for Adrien, but the Collector was there, waiting for them. Ladybug and Cat Noir started to battle the Collector, making sure not to get captured. He threw his staff at the villain but it was captured in his book then they retreated behind the staircase and made their way into Adrien's room barricading the door. Using a bike pedal, foosball table and his belt it resulted in the Collector's book being filled up defeating him.
After Gabriel returned to normal, Cat Noir rushed to him but when he asks about his son the heroes assured him that Adrien was safe and left (unknown that Ladybug was right.) After the book was returned, he admitted that he shouldn't have taken it without his consent in the first place. Adrien also heard that the book and him were the very last few things his mother gave to him before she disappeared. When his father came to a realization, Adrien asked if that meant he was able to go to school to which Gabriel agrees and Adrien hugged him. Then, he arrived at school and was happily greeted by his fellow classmates.
In "Prime Queen", Cat Noir appeared across from Nadja on a couch in the TV 5 studio. While waiting for the show to start, he jokingly told her that he loved chouquettes as the show almost aired he called Ladybug but received no answer. After the show's introduction, he and Ladybug engaged in a playful banter. When Nadja tried to get the two to admit they were dating, to Cat Noir's surprise, seeing a picture of them kiss on Valentines Day he asked when did that happen, continued to gasp in shock as the pictures continued. After Ladybug denied her claims, he jokingly said that hopefully one day they'd be a couple but was led out of the room by her with the excuse that Paris needed saving.
When Nadja said that everyone would be disappointed, he agreed with Ladybug if they were true fans, they'd understand leaving with her. Out of the studio, he asked her who needed help still believing her excuse and was informed that they needed saving from Nadja's questions. He retorted that was the price of stardom, but was reminded that they're superheroes, not stars. Following Ladybug, he proposed they go out for ice cream but their trip was halted by Prime Queen who was broadcasting from a billboard surprised to see Nadja akumatized. When invited to save Chloé, Cat Noir tested the billboard's intangibility seeing his staff pass through successfully the hero asked Ladybug if she was ready but she suggested getting there by their own means, he quickly rejected the idea, pointing out this was the fastest way.
Agreeing they both jumped through the screen, landing in the subway train where Chloé was held. After Prime Queen entered the room, they both agreed that Cat Noir would get the train's car door open and Ladybug would take care of Prime Queen. As she disappeared through a screen they were trapped inside, he suggested using his Cataclysm but was stopped by Ladybug, insisting they use it for an emergency confused, he called their current situation an emergency. But they needed to lure Prime Queen out to get her akuma deciding to play along, to the hero's surprise, his hand was grabbed by the heroine and confessed that they were in love to Prime Queen. As the train stopped he had Ladybug land on top of him causing him to purr in delight. Once again the villainess demanded they remove their miraculous so her ratings could max out, to prove their feelings he tried to kiss Ladybug but to his dismay, was rejected.
This time, she was threatening to push a trapped Alya into the Seine River. The heroes tried to follow through the screen to the Louvre, but ended up in a freezer. He again proposed to use Cataclysm but Ladybug saw no point in doing so and tried to kiss her, but was again rejected, so she used her Lucky Charm receiving a roll of tape. As Ladybug searched for another object to use with her Lucky Charm. Cat Noir urged her to hurry, as the tomb holding Alya was almost completely out of the screen. Using a pizza box, Ladybug taped onto the screen then, they baited her into the freezer, saying that they were taking off their miraculous and about to kiss. When she reached through the screen, they pulled her in and subdued her. The cat used his staff to break Prime Queen's watch, his Cataclysm to destroy the door and Ladybug purified the akuma saving Alya.
In "Despair Bear", Adrien was listening to Tom teach the class how to make macaroons. He followed the class out after the fire alarm went off. After everyone was outside, it turned out that Chloé had called the fire department. When she accused Marinette of the prank, Adrien defended her, asking why she would want to disrupt her own father's cooking class. Even though, Marinette wanted to report Chloé; because of her suspicion that she called the fire department during Tom's presentation; Adrien discouraged the idea, saying they couldn't proof it. As a result, Mr. Damocles punished everyone after no one confessed but, when Chloé got out of it Adrien was disappointed.
Then, he saw Chloé yelling at Rose for sweeping to close to her. Confronting her, he asked if she was the one who called the fire department, to which she admits, saying that "they all seemed to enjoy getting dirty making cookies." When Adrien heard this, he ended their friendship until she learned how to be nicer to everyone. Later, he was invited to a party that Chloé was throwing in an effort to be nice and rekindle their friendship. When Adrien saw that Marinette had suspicions about the party, he commented that sometimes Chloé can be nice. Then, Adrien was bumped by her and asked for a dance leading Marinette to the dance floor. Shortly after they began dancing, Alya and Nino helped fix their hand positions after they left, they continued.
But the party was interrupted when Adrien and Marinette saw Sabrina and Kim being controlled by the villain Despair Bear, they exchanged excuses and rushed off to transform. As a controlled Kim tried to attack Ladybug, Cat Noir tripped him into the ball pit and made Despair Bear fly off his ankle. The heroes tried in vain to capture him however, he kept on jumping from person to person, leaving them confused. Until Despair Bear latched onto Cat Noir's leg and tried to take Ladybug's miraculous. When restrained by her, he made Cat Noir use his Cataclysm against her, but was pulled away by Chloé before he could. After Ladybug summoned her Lucky Charm, receiving a fork he followed Ladybug upstairs and began to fight her.
As they fought Cat Noir attacked Ladybug with his staff but when the villain was unraveled, he was freed from his control. While she purified the akuma, he watched the tiny Despair Bear and yet fell over because of Jean Butler's sudden increase in weight due to the Miraculous Cure. Afterwards Cat Noir rushed away when his ring showed he was about to transform back. After Chloé invited Tom over to teach them how to make macaroons, Adrien complimented Chloé on her kindness and renewed their friendship. After Adrien pinkie-swore that they'd be friends forever, she went on to insult everyone's macaroons. He laughed and told Marinette that Chloé would never change then asked her if he was able to have a macaroon. Marinette nervously told him he could and Adrien complimented her, saying her baking was as good as her dancing.
In "Riposte", Adrien approached Marinette after he heard her compliment about him being handsome thanking her. He taught her about the rules of fencing complimenting that she had good reflexes and soon was locked in a duel with the mysterious fencer after it Marinette claimed him the winner. He asked Marinette if she was sure of what happened when but she wasn't he offered the mysterious fencer a decisive match. When she refused he tried to follow her and doing so Adrien researched his opponent. But was interrupted when Riposte attacked and demanded a rematch and yet he refused to fight her in her current state. Then, Ladybug soon arrived but seeing her outmatched he threw her his opponent's saber but when the heroine was cornered Adrien dived in to save her but sprained his ankle in the process.

As Ladybug and Riposte fought he took the opportunity to transform but Plagg told him he was taking a lot of risks however was interrupted when Ladybug found him and made their way to Louvre Museum. While in the sarcophagus, disregarding Plagg's protest and knowing she needed help he transformed into Cat Noir. Despite having a sprained ankle he arrived just in time to help his partner. Along with Ladybug after a fierce fight and using a radiator the duo was able to defeat Riposte.
Afterwards he left to detransform and let his presence be known to Ladybug asking her about Cat Noir finally arriving and she was glad that he did and admitted he was better at fencing than she was. Seeing Ladybug leave Adrien secretly blew a kiss; outside the museum he makes up with Kagami believing the point was hers. But she remained doubtful he explained that it was Marinette's first time fencing. When she playfully admits that Adrien liked her he says that Marinette was good friend and waited to give Kagami a decisive match.
In "Befana", sometime before Marinette's birthday Adrien was talking to Alya about it but when they saw her listening he switched the subject about taking Alya's sisters to the dentist. After the preparations were done he along with his classmates wished her a happy birthday and gave Marinette a small gift but before she could open it Befana ruined the celebration. Finding a quick place to hide Adrien transformed into Cat Noir. The cat tried to defend Marinette from her akumatized grandmother but was under attack by her minion but thanks to Marinette's friends they provided him with an opportunity to get her to safety.
Carrying her away he said she must be a very cool girl if her friends are willing to protect her and asked Marinette why her grandmother was freaking out she explained that her grandmother wanted to spend more time with her. After getting Marinette to the Eiffel Tower the hero told her happy birthday before leaving to deal with Befana and her angels. Upon finding her, Cat Noir used his staff to block the way and broke into a song with Ladybug finishing it. As they fought Befana's angels he saw the villain was heading towards the tower and tried to steer her ride in another direction but got knocked off and caught by Ladybug. After the angels were dealt with Cat Noir noticed that the akuma was hiding in the Befana's candy bag, once the heroine summoned her Lucky Charm receiving a tuba he was surprised that she knew how to play but Ladybug retorted she didn't.
Soon the ground crumbled below them and the duo was surrounded when he heard Ladybug admit defeat and then winked at him. Cat Noir played along admitting to her that Marinette was here leading the way separating Befana from her angels. Worried that he betrayed her he was relieved not to find her in the closest and was assured by Ladybug that Marinette was safe. By using Cataclysm on a fire hydrant and the tuba; the heroes were able to save Marinette's grandmother. Returning to the party, Adrien gave his gift to Marinette a lucky charm bracelet he made himself, explaining that he always carries the bracelet she gave him everywhere he goes. As the party goes on Adrien smiled at the bracelet.In "Robostus", Adrien was having science with his classmates, after watching Max and Markov fix the computer system he marveled at the sight of the little robot.

But knowing where Robostus was going they went to the Parc des Princes stadium. During their fight, he and Ladybug were surrounded and captured, then Cat Noir was asked if could use his Cataclysm but couldn't due to being restrained.
Since the cat was unable to see he asked Ladybug what's going on and heard that Robostus wanted to use their jewels to make a wish to become human. Which he found strange because he knew that it was Hawk Moth that always demanded their jewels. They were about to have their powers taken but thanks to Max's intervention they were set free. After he dodged the machines the cat used Cataclysm on Robostus's robot and with a harp the heroes saved Max and reunited him with Markov.
In "The Dark Owl", over the past week Adrien has been transforming into Cat Noir to save The Owl who is actually Mr. Damocles trying to be his own hero.

However, he and Ladybug discovered Dark Owl's plot was faked just to lure them.

In an effort to fool Dark Owl, he was informed by Ladybug that they were going detransform but have their eyes closed thinking they were giving up for real he was hesitant until Ladybug assured him. As they did so, Adrien gave her his ring but she closed his hand; surprised he wanted to speak but his mouth was closed by Tikki. Once Plagg was recharged he retransformed and used Cataclysm destroying the crate. After another fight, they discovered that the akumatized object isn't on Dark Owl but back at the school.

Then, he left to meet with his bodyguard upon seeing him Adrien noticed an akuma heading right for him but akumatized August into Gigantitan instead. After he found a hiding place, he transforms into Cat Noir then after getting the baby's attention with his bell. He tried to lure the baby villain to the river but ends up getting caught and found by Ladybug. Quickly escaping the heroes discovered that the akuma was in Gigatitan's bracelet but after Ladybug's failed attempt he commented that she wasn't to good with kids either. After he heard of her plan to use the Eiffel Tower as a playpen he commented it would work in theory but was unsure on how to get him there, thinking it'd be simpler if Ladybug used her Lucky Charm.
He and Ladybug used themselves as lures and offered to sing the lullaby but she teasingly said they wanted to calm him down not burst his eardrums and the cat retorted back saying that he had a great voice and would serenade to her someday. However Gigantitan got distracted again until the cat got his attention with a car saying he enjoyed playing with cars too when he was little. Once they were at the tower Cat Noir attempted to use Cataclysm on the kid's bracelet, but got thrown off and crashed into Andre's ice cream stand and used it on an ice cream cone. Reuniting with Ladybug, with not much time left using a treat as a disguise and Cat Noir's bell the duo was able to finally capture the akuma where Ladybug admitted he was good at taking care of babies and reunited August with his mother.
Meeting up with his bodyguard, Adrien was approached by Marinette who asked if he could hang out with her but seeing his bodyguard's frustration he turned down her offer. But offered her a ride home instead, however from her mixed up answer she turned him down by saying she would take a coleslaw home but (meant to say rickshaw). And yet, he told Marinette to enjoy her dinner and see her at school tomorrow.
In "Glaciator", Adrien transformed into Cat Noir and worked with Ladybug to save people from a runaway bus. After that he invited her to have a rooftop dinner with him as a chance to know each other but she had other plans accepting that he said if her plans ended early she could join and went home. Then, Adrien was at the dinner table waiting for his father but was informed that he wasn't coming leaving him disappointed and texted Nino that he couldn't come to their night out. Afterwards, he returned to his room; gave Plagg a piece of Camembert telling his kwami to fuel up and used his phone to make it sound like he was practicing piano. Determined about his date with Ladybug, Adrien told Plagg even though she didn't say yes she didn't say no either.
But nonetheless, he transformed into Cat Noir, left his room heading towards the balcony date spot, finished the preparations and waited for Ladybug. After being let down by her, he blew out all the candles and was extremely heartbroken noticing Marinette not too faraway. Cat Noir approached her asking if he could stick around not wanting to be alone and remembered meeting her once when she mentioned about having bad luck about the supervillain being in love with her. He related to having relationship problems of his own and spoke of the special dinner date he planned for Ladybug but she didn't show up. Through their conversation Cat Noir saw that Marinette had her heart broken too wanting to cheer her up, he took her to the date spot he prepared but was still glum that his lady didn't come. And yet expressed hope she would but as Marinette tried to cheer him up they were under fire by Glaciator finding a place to hide the hero asked her if another villain had a crush on her but Marinette said no. Taking Marinette home he was thanked by her for cheering her up.
Finding Glaciator, Cat Noir tried to fight against him but was sent flying until he was caught by Ladybug. Angrily he asked her how her date went with her "friends" but after evacuating people to safety and taking cover themselves they saw that Glaciator didn't attack couples. When he heard of Ladybug's idea for them to act as a couple he refused saying it's not cool to play with people's feelings and attacked the villain but failed until he was shielded by the heroine. Taking cover again and seeing that the cat was angry at her for missing their date she apologized, seeing her sincerity he apologized too and went along with Ladybug's couple plan. After they got close enough they discovered André was inside the monster and using a makeshift propeller and Cataclysm on a bus they were able to save Paris from being buried under a mountain of ice cream.
Now alone so they could talk at the dating spot, Cat Noir discovered Ladybug was in love with someone else but considered him a close friend. Respecting her honesty he told her she was his best friend too and gave her a kiss as well as a rose complimenting it went with her costume before leaving. Returning home, Adrien was asked if he had a heart ache over Ladybug rejecting him, but he didn't still held onto hope that she would love him someday and accepted his friendship with her. The next day, Adrien approached André's ice cream stand as he heard that his ice cream was magical and said you have to believe to make it work and André agreed then was given a cone that made him think of Ladybug and enjoyed his ice cream.
In "Sapotis", after Adrien witnessed the damage the Sapotis had done on television he transformed into Cat Noir. Meeting up with Ladybug, he saw her destroy the monster's hat and asked how did she know and said it was through trial and error. But saw that there was no akuma and discovered that they had to destroy the original hat. He quickly understood that they had to capture them all but after going through many clones they had no luck soon he and Ladybug got completely overwhelmed and surrounded. Then, he was confused when Ladybug's Lucky Charm gave her a teapot as he battled more Sapotis' he told the heroine that his kung fu wasn't enough. Once Ladybug understood the teapot's purpose, Cat Noir was shocked that she had to leave but trusting her he told her to go. The hero did his best to hold off the Sapotis' but wondered what was taking Ladybug so long and was overwhelmed again.
He almost had his ring taken until Cat Noir was saved by Ladybug and their new ally. Upon seeing her he was amazed as the cat thought he was Ladybug's only superhero friend and was introduced to Rena Rouge welcoming her to their team with opened arms. For the moment he enjoyed playfully teasing Rena seeing that working with her was going to be fun. But they were surrounded again and retreated to higher ground while Ladybug gathered the materials she needed Cat Noir and Rena Rouge drove the little monsters back. Then, moved to a new area to enact Ladybug's plan seeing the Sapotis close in he told Rena it's time to use her mirage powers. After instructing her, he noticed that she would transform back soon but wasn't worried as he could keep her secret but when Rena refused Cat Noir praised her for learning fast. When the fox voiced concerned if the plan would work he assured her it would and after collecting all the hats he used Cataclysm to destroy them. Once Alya's sisters were returned to normal, Rena Rouge had to leave but he looked forward to working with her again and returned the twins home.
In "Gorizilla", Adrien approached his father asking for a favor but when he heard Gabriel's response he realized it'd be too late by then and leaves. Soon he snuck out of his room and made his way to the Paris streets trying to keep a low profile which was easier said than done when he came across a fan named Wayhem. Soon his picture was posted on the internet, noticing his bodyguard he tried to run but was soon chased by a mob of fans. Until he ran into Marinette knowing she lived close by Adrien asked if he could hide at her place but hearing the fan mob he realized it was too late. Following her, they hid in the park fountain where he thanked her for hiding him as people went crazy over the new ad he modeled in. Marinette expressed excitement over it but Adrien was embarrassed by it and yet surprised to see her in pajamas.
Remembering the task at hand, they both came out of hiding but upon seeing his body guard Adrien pulled Marinette back down. Explaining that he left his house without permission but they were spotted by another fan who took a picture of them and had to move again. Arriving at the train station Adrien apologized to Marinette for dragging her into this and for the idea of people thinking she was his girlfriend but she said flusteringly it was no problem. He was asked if his father was going to be okay with this, Adrien retorts how could anything bad happen and pulled out his Lucky Charm. And yet, their moment was ruined by another fan mob realizing they couldn't stay he grabbed Marinette's hand and tried to run but was quickly surrounded seeing their only means to escape he pushed her into an opened train car.
Upon wearing disguises the duo made it to the theaters and Adrien was complimented by Marinette for coming here. He told her this was actually where he was going when the fan mob showed up because the theater was showing a movie where his mother was playing the leading role. However, as soon as Adrien took off his helmet he and Marinette were swarmed again things went from bad to worse when Adrien's bodyguard was akumatized into Gorizilla and was taken captive. Being carried to the tallest building he apologized to Ladybug for all the trouble seeing at Ladybug's urging he jumped off the building seeing him plummeting to his doom Plagg advised him to transform but couldn't. And yet, he was caught by Ladybug landing safely on the ground he almost called her his lady but caught himself.
However, he noticed she was about to detransform but Gorizilla was still on the loose and carried away by the heroine. Then was asked where the villain's akuma might be noticing Ladybug's time he advised that he'll hide while waiting for Cat Noir to show up but she retorts by saying it'd be too late by then having an idea he heard of his partner's plan. He agreed to act as bait but also heard Ladybug say that she needed his Cataclysm for it to work when he voiced concerns about him not showing up the heroine says she trusts him. However, Adrien was asked by Plagg on how was his going to pull it off since he couldn't be in two places at once. With Wayhem acting as his double they transformed into Cat Noir using Cataclysm on the ground below the heroes were able to stop Gorizilla.
Coming from his hiding spot Adrien thanked Wayhem for filling in for him and believed that the incident changed Wayhem's opinion of him but Wayhem said he had the best day ever being in Adrien's shoe for a bit. Upon hearing his apology Adrien gave him his email address believing that the two could be good friends. Returning home, he was met by his father believing he'd be angry but to his surprise Adrien saw the movie sitting next to his father he was reminded that all he had to do was ask and they had to trust each other as they continued watching the movie.In "Captain Hardrock", Adrien was playing a piece on the piano with his father watching upon making a sour note he was stopped by him. Then, he was asked if he had been practicing that's when Adrien suggested that he would improve if he played with others but Gabriel retorted against it. Then, when he mentioned about going to his friend's concert but ended up being grounded and was told to continuing practicing.
As Adrien practiced he was approached by Plagg who tried to cheer him up by saying that he could enjoy the concerts from the comforts of home. But he said that his friend's concert was all that mattered Plagg tried to sing Adrien his own concert appreciating it but was still bummed.
When they witnessed Captain Hardrock's destruction he knew needed to be done and transformed into Cat Noir. With Ladybug the duo tried to control the ship or anchor it with no success, but by using a chain on the ship's compass the vessel ran aground with everyone on solid ground Cat Noir used Cataclysm and destroyed the ship. Back at his room, he asked his father if he could play with him as a duet afterwards Gabriel agreed to let him attend his friend's concert. Making it in time he meets Luka and takes part in the concert as the band's keyboard player.
In "Frightningale", at home Adrien heard from his father that Clara was a fan of his and seeing this as a promotional opportunity for Gabriel's business in other countries. Adrien was surprised that he was going to part in Clara's video, but seeing that the costume looked like his Cat Noir costume he almost refused until his father inisted. At the studio, Adrien looked himself in the mirror while Plagg was very impressed with the costume but he felt uncomfortable. The kwami agreed that he wasn't to fond of the bell but admitted the costume was something Adrien wanted deep down.
However, he was more concerned with everyone figuring out his identity until Plagg assured him they wouldn't. Then, had the idea to act as lame as possible so the crew would pick someone else and was surprised at the number of people that auditioned to be Ladybug including Chloé, when his father asked about his mask Adrien said he couldn't find it and also heard that Marinette changed her mind about Clara's offer. Despite being nervous they were doing alright until it was time to put on the masks despite the duo claiming that they had lost them they were easily found. Just before Adrien put on the mask Chloé came into the studio and cancelled Clara's shoot which caused the singer to be akumatized into Frightningale. Finding a hiding place he and Plagg transformed into Cat Noir however even with Ladybug they found it difficult to fight her and became affected being forced to sing and dance. But thanks to a pair of handcuffs the heroes movements were synced preventing them from being turned into statues. Then, used Cataclysm on Frightningale's mike, the Miraculous Ladybug returning everyone to normal and saved Clara.
Watching Clara's new video from the school's library Adrien says he liked this version believing he couldn't have pulled off being Cat Noir. With Marinette believing that he didn't look a thing like the hero he complimented Marinette believing that Ladybug wasn't as funny as her leading to everyone sharing a laugh.
In "Syren", Cat Noir worked together with Ladybug and Rena Rouge to round up some escaped zoo animals leading a pair of panthers into a cage. When he saw that Ladybug and Rena had to leave the hero expressed annoyance about being kept in the dark and the heroine explained that she would talk to him about it and voiced that he hated secrets. Returning home, Adrien voiced out his frustrations about Ladybug keeping secrets from him through his action figures and asked Plagg if he knew anything but the kwami couldn't be swayed. Until Adrien tried to bribe him with cheese and continued until he noticed his room was filling up with water but told him this wasn't over before transforming.
Seeing the streets flooded he found Ladybug telling her that he didn't know she was going swimming but understood that cats weren't crazy about water and knew that they had to fight Syren underwater. The cat jokingly asked Ladybug about summoning her Lucky Charm and received a potion bowl, upon seeing it he said they could scoop out the water but it'd take forever. After Ladybug understood it's purpose Cat Noir had to wait while his partner sought out help becoming annoyed again about secrets. Fed up with waiting Adrien detransformed, grabbing his ring he threatened to quit being Cat Noir if Plagg didn't tell him what Ladybug was hiding. When Plagg retorted he shouldn't do that he reminds him that no one would know or care. Until Plagg mentioned that he would care if Adrien quits and believes the reason would be his love of cheese. And yet, the kwami admitted that he was close friend and making Adrien smile then they were approached by a man. The boy quickly noticed him as the man he helped before and was informed that everything would be explained later as well as that Ladybug needed help being given a green vial Plagg understood what it meant saying he hated transforming.Now with the playing field leveled in their new "Aqua Mode" Cat Noir joined Ladybug by bringing the villain to the surface they defeated Syren, saved Paris from flooding and thanked Ladybug for keeping her promise. Back at the mansion, Adrien was practicing his Chinese until was approached by Mister Chan posing as his substitute tutor. When Nathalie left, Plagg officially introduced him to Master Wang Fu the guardian of the Miraculous. So he could understand more about the magic jewels and was also given a box of Camembert cheese with each wedge containing different powers when the time came to use them.
In "Zombizou", in the Locker Room Adrien heard that it was Miss Bustier's birthday like his classmates he prepared a gift for her expressing joy that she was his teacher. Along with his friends he was amazed at the gift Marinette prepared and asked Chloé if she made one too. Afterwards, Adrien went to his classes finally arriving in Miss Bustier's he wasn't too surprised that Marinette's gift was ruined by Chloé. Upon Ms. Bustier's returned he was shocked to see that she was akumatized into Zombizou, but thanks to Ladybug's intervention he and his classmates escaped. But upon seeing something wrong with Sabrina he discovered that the kisses were contagious an ran into the Locker Room with the others.
Upon opening his locker Adrien pretended to be infected seeing his act Plagg asked him if it was a trick to get a kiss out of Ladybug but he said that he needed to work under the radar and transformed into Cat Noir. Meeting his partner on the roof he understood that Zombizou was after Chloé with the zombies closing in; eyeing a nearby bus he was asked by Ladybug if he knew how to drive and answered yes. Using his staff and belt they got everyone safely inside but his driving skills weren't very good so they decided to take Chloé to the Eiffel Tower. Carrying her the rest of the way, he saw that his partner was distraught at losing the rest of their friends. And yet, comforted Ladybug by reminding her that she'll fix everything in the end. Reaching the top of the tower he was surrounded by Zombizou's minions and tossed Chloé to her. While trying to keeping them at bay it was only a matter of time before he came under the spell he told Ladybug that he'd chill out here and if they were going to end up kissing he'd rather do it after the madness was over.
Even though, Ladybug refused to leave Cat Noir said she was the only one who could fix this and then collapsed under the minion's weight. Now fully a zombie he used Cataclysm to get into the office and tried to kiss Ladybug but latched onto Chloé instead. When everyone was cured by the magic ladybugs he was pushed away by her, after Zombizou's defeat they heard Chloé's heartfelt apology to Miss Bustier being proud of and returned home. Then, Adrien went to school the next day.
In "Frozer", after saving a runaway para-glider, Cat Noir had a daydream in which he presented Ladybug with a rose asking again if she'll accept him as her boyfriend and revealed his identity to her but was brought back to reality by Ladybug. He was informed again that she was in love with another guy (unaware that it's his alterego). And yet, asked Ladybug would she give him a chance if this guy wasn't around but she answers she can't imagine (unaware that she has a crush on his alter ego). They detransformed and went off to school.
Adrien came to fencing pratice but was easily beaten by Kagami. In the locker room, he told her that he was having trouble with his love life and was advised to change targets. When Adrien thought about changing his game Plagg gave him advice on how he greets Camembert although thankful his wielder told him that his advice might be best suited to someone else. During a visit at the ice rink Plagg was surprised that Adrien left Kagami for Marinette but Adrien told him she's just a friend wanting to check if she was okay. But soon the whole ice rink and all of Paris was getting covered in ice because of the akumatized villain Frozer. Thanks to the heroes new Ice Mode they were they transformed into Ice Noir, however due to their previous encounter he gave Ladybug the "cold shoulder" leaping off as he preferred to track and observe.
But upon seeing Frozer as well as Ladybug under fire he ducked in to save her admitting that they needed a plan and was admired for he is observing skills and with a bag of salt they were able to save Paris from being a frozen wasteland. Returning to the ice rink he helped Philleppe save it while informing Kagami that he won't change targets and she accepts his decesion leaving for home. However, he soon hears Marinette greeting her Adrien hears Marinette's offer about going to the ice rink again surprised he asked just the two of them. That's when Marinette flusterling asks of bringing the whole gang answering that he'll clear his schedule.
In "Style Queen", Adrien was getting ready for Fashion Week show but felt awkward with Plagg commenting he looked ridiculous but heard someone coming and saw Marinette. To whom he saw looking incredibly nervous but assured her that her hat design was great or his father wouldn't have picked it as the winner of the contest. He briefly showed it off to her to whom he thanked for the compliment. Then, the show went well and Adrien shared a quick glance a Marinette until Style Queen attacked looking for Gabriel. He proclaimed that his father wasn't here; which ended with him being turned into a glitter statue. Then held prisoner by the villain at the Eiffel Tower and was given Style Queen's flower along with a protective force field but was fading away. After the villainess' defeat, he was revived with the Miraculous Ladybug (superpower), brought back to the show by Ladybug and thanked her for saving him.
In "Troublemaker", Adrien was watching the show "Fill My Shoes" in his room and was asked by Plagg why he was watching this show. He said the show was being filmed at Marinette's house as the showed continued he was surprised to see that she had many pictures of him. When he saw that Troublemaker had appeared he transformed into Cat Noir and went off to the bakery once there he tried to open the locked gate but with no good. The cat attempted to use his powers but the villain heard what he was doing and threw him into the side of a van until Ladybug pulled him up to Marinette's Balcony.
Landing on Marinette's bed, he eyed her many photos until Ladybug averted his gaze but upon hearing Troublemaker's attack he used her bed in self-defense. Cat Noir and Ladybug tried to fight the villain but had trouble to do her intangibility when he saw Troublemaker trying to take Ladybug's earrings he tripped her and knocked away the villain's pen. Also he understood the villain's power was also her weakness resuming the fight Cat Noir almost had his ring taken but was prevented by Ladybug and yet was tangled in her yo-yo. Seeing his partner's forced detransformation he freed himself and used Cataclysm to have the villain drop the earring. Back on his feet he told Ladybug he wasn't expecting her to share her identity like that.
Still holding in his power after the heroine summoned her Lucky Charm receiving a broken plate. At first, when Ladybug didn't see how to use it Cat Noir suggested maybe losing an earring weakened her power. Following her back to Marinette's room per part of the plan he proceeded to check outside for Troublemaker. Upon hearing the broken plate he reenters the room revealing their trick (super-gluing Ladybug's earrings). With Troublemaker solid Cat Noir was able to grab the pen and destroy it deakumatizing Penny. Joining Ladybug on the balcony he was playfully told that he won't be finding out her identity and Cat Noir retorts calling her the girl of his dreams.
At school the next day, Adrien approached Marinette in the locker room to check on her albeit surprised her by accident. Then, asking about the photographs he hears from Marinette that she's really into fashion. In a teasing manner he asked if she was lying but understood saying he got use to having lots of fans as well as photographs of him everywhere. Knowing of Marinette's passion he asked if she like to come to his next photoshoot hearing her response Adrien said he'd keep her posted. Leaving he told Marinette that he'll see her in class and was happy to have her as one of his fans.
In "Queen Wasp", the show resumed with Adrien showing off Marinette's hat until he was surprised as everyone to see his father and even more so received a hug from him. After the show was over he encouraged Marinette to stand proud for her design, when he heard that she had the chance to go to New York Adrien was happy as well as excited at the idea of modeling for her. He asked Chloé if she felt the same but was saddened to see Audrey disregard her and was shocked when Chloé transformed running off with the Bee Miraculous. He was escorted back to the limo and home with his father hoping Chloé doesn't do anything reckless. Upon hearing about the "runaway train" Adrien and Plagg quickly transformed into Cat Noir.
After he and Ladybug stopped the supposed "runaway train", Cat Noir was angry at Chloé for using her powers to create a problem. When Ladybug demanded the Bee Miraculous back and Chloé refused with shock he easily figured out that his partner lost it and yet was pulled away by her reminding him of the events of "Style Queen". But soon they realized Queen Bee was gone and chased after her back to the hotel but the job of retrieving the Miraculous was harder than they thought as they found Chloé akumatized into Queen Wasp with it and paralyzed everyone. During the fight they realized the akuma was in her jewel but had trouble getting to it without being stung, they managed to escape the swarm by going underwater. Coming up for air and seeing that Ladybug's Lucky Charm gave her a snorkel he said the charm had a funny sense of humor taking in the fact she won't drown.
With that in mind Cat Noir and Ladybug used trashcan bins to protect themselves and went back to the hotel. By taking the fight underwater they avoided Queen Wasp's swarm and using Cataclysm to destroy the jewel the heroes returned Chloé to normal and resurfaced. But thanks to the Miraculous Ladybug, the jewel was restored, he and Ladybug looked sadly at Chloé saying it must be returned but was begged by her for another chance. After seeing her get disregarded by Audrey again Cat Noir comforted her understanding why she did this and along with Ladybug encouraged her to do the right thing. With the Bee Miraculous returned, he accepted Chloé's apology and returned home.
In "Reverser", Adrien saw Marc and Marinette spying on Nathaniel saying it's not cool to spy on people. But she nervously explained that they were working on a surprise for him. Accepting her answer he said that was thoughtful of her and offered his help if she needed it leaving the school. On his way home Adrien along with his bodyguard became struck in traffic. Looking out his window he was shocked to see Ladybug flying through the air by the villain Reverser. He told the Gorilla that he left his fencing gloves behind saying he'll meet him later and quickly transformed into Cat Noir. Meeting with Ladybug, he was ready to take on Reverser, but being distracted by his partner the cat became an easy target causing him to be afraid of everything. Which caused them to fall into the river; pulling themselves to shore Cat Noir was worried he'd catch a cold but was reminded by Ladybug that they had to stop Reverser. Still afraid he didn't want to fight but was encouraged by her to pursue him by looking for Nathaniel they tried to leave but realized they weren't going anywhere.
Taking a cab to the school, the heroes saw that Reverser beat them there and yet eyeing one of Nathaniel's drawings they discovered that he's at the Louvre Museum. Where the scaredy cat realized they had to take another cab making it to the museum they asked him for help. After hearing the news he asked about Marinette but Ladybug said there was no time, knowing he wouldn't be much help Cat Noir opted to stay behind. When Alix offered to help the hero was welcomed to it heading to Eiffel Tower the group saw the space dumpsters coming down which caused the kitty to shake in fear under his blanket.
But was comforted by Ladybug knowing they could do this, Cat Noir knew even with powers messed up they were still a team. As apart of the plan he and Nathaniel were purposely given to Reverser but the hero was actually blindfolded and tied to a makeshift kite. With Alix doing the steering he used Cataclysm on the villain's hoverboard, thanks to his confidence being restored by the Miraculous Ladybug. He caught Marc setting him on the ground and was happy they returned to normal.
In "Anansi", through video chat on his phone Adrien along with Marinette at Alya's house watched and admired how Alya and Nino were in perfect sync with each other expressing that he'd wished that he had someone like that. But when Marinette voiced disappointment that he wasn't allowed to come, Adrien didn't take it too hard seeing that one day his father won't see him as a child anymore. Then heard from Alya's sister Nora that Alya wasn't allowed to go out because of the danger of akumatized villains. When Alya spoke of her sister's overprotectiveness Adrien learned from Marinette when they were out Nora attacked someone who she thought was akumatized but was actually a normal guy in a costume. Then, he refereed the arm wrestling match between Nino and Nora and saw that Nino won.
After he saw his friends in danger he and Plagg transformed into Cat Noir. However with Anansi's great strength the heroes found it difficult to fight against her. Soon the cat was caught in Anansi's web and when the villainess went for the ring Cat Noir invoked his Cataclysm to protect it. With the help of their new ally Carapace the hero was set free, used his powers to destroy Anansi's helmet and save Alya.
In "Malediktator", Adrien along with his classmates watched Chloé’s documentary but unlike everyone else he couldn't laugh about it and was shocked when she stormed off. Sometime later, he heard from Marinette that Chloé left for New York leaving him saddened. However, when Marinette talked ill will about her Adrien retorted that no one is useless and that she was his only friend growing up with that in mind he couldn't celebrate her unhappy departure. But soon Malediktator enters the scene and Adrien transforms into Cat Noir after a brief scuffle he and Ladybug retreat to higher ground. After Ladybug summoned an abacus with her Lucky Charm the cat says he'll take care of Malediktator while she figures out how to use it. He attempted to use his Cataclysm on the super mayor but it left Cat Noir wide open leading him to being hit with Malediktator's bubbles turning him into a real cat. Soon afterwards he becomes Audrey's pet and yet he was still wary of the villain clawing away at him.
Soon Cat Noir was napping until, he caught eye of a dot from Ladybug's laser pointer while trying to catch it he knocked out the guards leaving Malediktator defenseless and was soon returned to normal by the Miraculous Ladybug cure. Joining the ladies he was disappointed that he missed out on a party and yet was proud that Ladybug and Queen Bee were working together for real. After Chloé left with her parents he apologized to Ladybug for not being helpful but she retorts saying that he was big helped surprised he asked for details but with her time almost up Ladybug said she'll tell him next time.
The next day, Adrien attended another party for Chloé but this time it was her heroic actions as Queen Bee and praised Marinette for it.
In "Sandboy", Adrien was reading a book in his room and wished Plagg a goodnight who was going to bed (but snuck out). After awhile he saw his room change into cage bars, he tried to wake up Plagg but was horrified that he was turned into a sock. As the bars started to close in on him Adrien tried to call his father or Nathalie for help but to no avail. He desperately tried to break the bars but it was unless until Plagg arrived; Adrien was relieved he wasn't a sock but wanted a good explanation. He quickly transformed into Cat Noir and used Cataclysm to break the bars.
He found the city a mess of living nightmares and was joined by Ladybug, however it wasn't easy fighting Sandboy with his sand blowing everywhere. After seeing his partner become powerless because of it he defended her and soon got struck with the sand too but still had his powers. The cat explained losing his wasn't what he feared most but Ladybug hating and trying to destroy him. Fighting an evil Ladybug while defending the real one he advised her to come up with a plan quick as he was about to detransform. By tricking the evil Ladybug and using a piece of her weapon the duo was able to defeat Sandboy. Upon hearing what happened the young boy explained he was akumatized because of a nightmare, saying that's what happens when you let kids watch whatever they want on tv with little time left Cat Noir asked Ladybug to return the young man home. After that he was asked by Ladybug if he really thought she was anything like his nightmare he replied she wasn't calling her the girl of his dreams.
He returned home and was approached by Plagg who hugged him saying thank you. Confused he asked Plagg if something was wrong but the kwami thanked him for letting him his freedom mostly. And yet Adrien completely understood why Plagg left saying he knew what it was like to have restricted freedom and all he had to do was ask. Touched he was embraced by Plagg again calling him the best Cat Noir ever but he doesn't want he him to get too mushy about it.
In "Catalyst", after dealing with a late night akumatized villain Adrien returned home and detransform. While Plagg was eating Camembert he already knew they were heroes and wanted to go back to bed until Adrien explained that today was Heroes' Day where everyone has to do one good deed. However that's when Hawk Moth commenced his biggest plan yet. By amplifying his powers the mastermind sent a swarm of red akumas to the school, Plagg and Adrien attempted to transform but was halted by Gorizilla. With the okay from Adrien, Plagg used Cataclysm on the street setting his wielder free and transformed into Cat Noir then joined with the rest of his allies.
In "Mayura", despite the team putting up a good fight Cat Noir and Ladybug lost their allies as well as they were about to detransform back. But thanks to him using Cataclysm on the ground below them the duo escaped, afterwards he gave Plagg a piece of Camembert to recharge and accepted to share it. When he heard Ladybug express doubt on how to beat Hawk Moth commenting that he found a way amplify his powers like they did. But remaining unfazed he gave Ladybug words of encouragement if their team crumbled then he proposed to go back to being a duo and do what they do best giving people hope. Soon they were found by the army Adrien and Plagg retransformed into their Aqua Mode but upon resurfacing they still found themselves outnumbered.
But with the Paris Rebellion's help along the way he and Ladybug see the reason to keep hope alive. Making it to the tower they managed to corner Hawk Moth and summoned his Cataclysm despite Scarlet Moth trying to reason with the duo Cat Noir wouldn't listen aware of the consequences of such a wish. Soon as he and Ladybug closed in Scarlet Moth, he was pushed out of the way by Ladybug to discover the Scarlet Moth they were talking to was an illusion leading to a fight with him; the hero manages to catch the mastermind's cane destroying it and deakumatized everyone. They were locked into hand to hand combat with him but lost and yet were saved by Rena and the others.
He and the team were about to close in on him again but they were blown away by a Moth creature. After the creature disappeared they all noticed a feather realizing their archenemy had help thanks to the Peacock Miraculous holder and that Hawk Moth escaped but managed to save the city. With Cat Noir's time almost up he retrieved the Bee Miraculous from Chloé and returned it to Ladybug. Afterwards, Adrien attended Marinette's picnic sitting next to her but soon had to leave for his father's banquet but before he left.

As he left he was approached by Marinette and surprised that she kissed him on the cheek to express her thanks and quietly thanked her.
In "Chameleon", Adrien saw that Lila had returned to school and yet still wasn't fascinated by her stories. Then, he was approached by her asking if he could help her with her homework because of her tinnitus. Calmly Adrien said that he isn't against helping her but urged Lila to be honest with him and if she continues her lies she'll make enemies instead but watched Lila storm off.
Soon afterwards Adrien was put to sleep by an akumatized Lila and shoved into a locker. Thanks to Lila changing into someone else he woke up asking Plagg what happened he explained that Lila put him to sleep with an enchanted kiss. Realizing that she was reakumatized they transformed to Cat Noir, despite being put to sleep by Chameleon again Ladybug was saved. Upon being woken up again he saw that the heroine managed well on her own. When she wondered who the akumatized villain was Cat Noir told her it was an old acquaintance and knowing it was Lila.
He was happy at the fact that Ladybug and Lila made amends unknown that her play at peace was also a lie. When he saw Marinette's attempt to expose her Adrien talked her down saying that humiliating her won't set her straight.

When Adrien points out that Plagg does the same thing he says he's only looking for cheese and counts his Camembert.
Then, sometime later he and Adrien were approached a once again akumatized Kagami, seeing her leave to punish Lila.

However, their first fight with Oblivio resulted in him using Cataclysm and being struck by the villain. In the elevator he woke up and found a strange lady (his partner) inside with him asking who she was but couldn't remember. Eying his appearance he figured that they were at a costume party and yet something from inside told him that they were suppose to know each other. Upon hearing their Miraculous go off Adrien also figured they shopped at the same jewelry store and detransformed, seeing the strange creatures (their kwamis) he expressed no fear and introduced himself believing that were genies.
Realizing their condition Adrien remained calm but upon hearing the elevator collapsing above them he and Marinette tried to get out until they were freed by their anmensic kwamis. The duo tried to escaped the building but found all the exits blocked and that a strange villain was after them, hiding in the bathroom they try to recap everything that happened. When the strange creatures were hungry Adrien opened his shirt he was surprised to find Camembert, and his bus pass with his name, both he and Marinette reintroduced themselves. Realizing that they had their phones they tried to call for help but realized they were locked. Hearing Oblivio coming for them they hid in the stall and escaped through the air vent, admiring her creativity he called Marinette "a girl who always comes up with the right plan". Once the group escaped to another part of the building they resumed their phone problem. But upon calling his father Adrien only received his voicemail and hearing Marinette talking wih her mother he edged her to tell her mother about their situation.
But when she didn't he asked why being informed that they were the superheroes and were powerless leaving him more confused. Aware of his identity as a hero Adrien figured that they must known about each other's identities eying the many pictures of Marinette as Ladybug in his phone. Showing Marinette he believed that they were a couple accepting he couldn't hide his identity from the one he loved but was unsure what the flying creatures were, seeing one of them fly off he believed he was going to get help. Despite Oblivio was closing in on them again by having another diversion they manage to escape them and believed even without their powers they made a great team. From Marinette's phone Adrien learned what happened before he was struck by Oblivio and called her clever when she left a message for herself, containing Master Fu they figured out how to restore their powers.
Upon seeing Marinette transform into Ladybug, Adrien was amazed and aware that Marinette had already proven herself a hero both with and without the costume. Seeing her confused on how to use her Lucky Charm he advised that it was apart of a puzzle and had no doubt she'd figure it out, seeing her leave he wanted to go with her believing they were stronger together. Understanding her reasoning for him to stay out of harms, Adrien received a kiss knowing he didn't need his memory to why he loved her. However, seeing Ladybug having trouble defeating Oblivio Adrien dons a cardbox version of his suit and tries to rescue her but were both backed into a corner. Until Plagg arrived, happy Adrien quickly transformed and relearned how to use his powers again, with him as the distraction the anmesic duo defeated Oblivio.
Upon seeing their enemy detransform into two people Cat Noir was surprised and curious on what to do about the remains of Oblivio's power. Being informed that Ladybug had a second power allowing her to revert everything back to normal shocked he asked if they were going to remember any this and she sadly answers they won't. Realizing they'll forget being love Cat Noir asks Ladybug if he could kiss her which she allows and embrace before their memories were restored. However once everything was returned to normal they ask Nino and Alya if they seen Oblivio and answer that it was them. Cat Noir retorts that the two of them would make a good couple, but was reminded by Ladybug that she was in love with someone else, seeing Alya's of them he laughs and turns her head to it surprised. With that he told her they were meant to be together and that she was only one didn't see it, but was scolded by Ladybug saying this conversation was not over.
