Season 1
In "Ladybug & Cat Noir (Origins - Part 1)", Adrien opened the box that held the Cat Miraculous, releasing Plagg. Plagg greeted Adrien then flew around his room, searching for food until Adrien caught him. Plagg explained to Adrien what he was (a kwami), the powers he granted (Cataclysm), the duty that was given to Adrien (stopping the akuma and akumatized villains), and how Adrien would be able to transform. He emphasized that Adrien could not tell anyone about his existence. Before he could finish telling Adrien about his powers, Adrien transformed into Cat Noir. Together, with the help of Ladybug, they took down Stoneheart. However, because Ladybug did not capture the akuma, it multiplied and spread, creating more Stonehearts. Plagg explained to a disheartened Adrien that he did not have the power to purify the akuma and that only Ladybug could do it. He then went back to eating Camembert.

In "Stoneheart (Origins - Part 2)", Plagg escaped with Adrien to Collège Françoise Dupont where he hid in Adrien's shirt until Stoneheart reappeared. Adrien and Plagg transformed into Cat Noir and went after the Stonehearts. With the help of a parachute and Ladybug, they took down Stoneheart again. The next day in the rain, Plagg called Marinette "Adrien's girlfriend."

In "The Bubbler", Plagg started off the day by gifting Adrien a piece of Camembert for his birthday, but Adrien didn't want it, so he ate it. At lunchtime, Plagg convinced Adrien to not fight Nino--who had been transformed into Bubbler--and to party instead. When Ladybug landed at the Agreste mansion, Plagg danced until he and Adrien transformed into Cat Noir. They and Ladybug were bubbled, freed with Cat Noir's Cataclysm. Together with Ladybug's help, they defeated Bubbler.

In "Mr. Pigeon", Plagg and Adrien transformed into Cat Noir to help take down Mr. Pigeon. When they were captured by pigeons with Ladybug, Cat Noir used Cataclysm to escape into Le Grand Paris. Adrien detransformed in one of the hotel suites and Plagg complained, saying he was tired and his body ached. After devouring a wheel of Camembert, they transformed back into Cat Noir and followed the pigeons to the Grand Palais. By turning Mr. Pigeon's pigeons against him with a bag of popcorn, they defeated him with time to spare before the design competition.

In "Stormy Weather", Plagg hid in one of the containers at Adrien's photoshoot until Adrien enticed him out of hiding with the promise of a slice of Camembert. Because of Stormy Weather terrorizing people in the park, they transformed into Cat Noir. Ladybug and Cat Noir chased Stormy Weather across Paris, cornering her on the KIDZ+ studio roof. One smartly placed Cataclysm on a billboard and one captured akuma later, Ladybug and Cat Noir saved the day. Adrien detransformed and he and Plagg returned to the earlier photoshoot.

In "Timebreaker", Plagg went with Adrien to the Trocadéro to watch Kim's and Alix's race. When Alix was akumatized into Timebreaker, they transformed into Cat Noir and tried to help Ladybug. Unfortunately, they were erased from the timeline while protecting Ladybug. Back in the past, Cat Noir helped the two Ladybugs defeat the two Timebreakers.

In "Copycat", Plagg was eating Camembert in Adrien's bag on his cellphone while Adrien was at fencing practice. When Adrien opened his locker, Plagg told him about the new message on his phone and then they transformed into Cat Noir to go to the statue ceremony. Afterwards, they went back to the school and detransformed. Adrien grabbed his bag and they went home. However, they immediately returned to the school because Adrien's phone was missing. (Adrien blamed Plagg, but Plagg swore he didn't eat his phone.) On the way, they saw another Cat Noir stole the Mona Lisa. They transformed once again and hurried over to the Louvre but were captured by the police. They escaped through the subway system and detransformed. Plagg guessed the thief was akumatized and Adrien agreed. He then accused Adrien of being jealous, but Adrien ignored him. They transformed again and went to Théo's studio where Cat Noir was captured by Copycat. Ladybug arrived and freed Cat Noir with Copycat's Cataclysm. Using a spoon, Ladybug and Cat Noir defeated Copycat and returned the city (and the Mona Lisa) to normal.

In "The Pharaoh", Plagg was eating cheese and ignoring Adrien's attempts at discussing whether Ladybug went to his school and cheese being better than girls. When Adrien saw Alya's new livestream, he and Plagg immediately transformed into Cat Noir and went to the Louvre. Plagg was impressed with the Pharaoh's face changes. Cat Noir arrived just as the Pharaoh was trying to leave. Before they could land a hit, Cat Noir was thrown into a sarcophagus. The Pharaoh escaped with Alya while Ladybug freed Cat Noir. They were still trapped in the room, so Cat Noir used Cataclysm to break the bars of the exhibit. Cat Noir left Ladybug to detransform and feed Plagg cheese. When Plagg was filled up, they transformed again and freed Ladybug from a time-shifting bubble. Cat Noir then went to distract all the mummies and give Ladybug time to save Alya. They trapped the mummies in a bus. When Ladybug saved Alya and the city, they went home.

In "Lady Wifi", Plagg was Cat Noir with Adrien, late to an akumatized villain battle, and helped Ladybug defeat the villain. The next day after Adrien learned about Alya's theory of Chloé being Ladybug, Plagg teased Adrien for being in love with Chloé. Adrien rebuked him and then they transformed into Cat Noir. They went to Le Grand Paris to stakeout Chloé's room with Ladybug. They entered her room when Lady Wifi appeared, tried to trap her in the basement, and were themselves led to Lady Wifi's trap in Le Grand Paris' restaurant. Cat Noir was trapped in the kitchen's freezer, the impact of being thrown in there forcing the Cat Miraculous off Adrien's finger. Adrien found it before Ladybug managed to free them and re-transformed, protecting his identity. Cat Noir followed Ladybug's plan to defeat Lady Wifi and destroyed the WiFi antenna above the hotel, thus cutting her off from her powers. Ladybug appeared and helped defeat Lady Wifi and return the city to normal. With only a minute left on her Miraculous, Cat Noir followed Ladybug downstairs. She detransformed in a closet. Cat Noir left the building and detransformed. Plagg thought Adrien was crazy since he didn't look to see who she really was. Plagg didn't understand humans and went home with Adrien for the night.

In "The Evillustrator", Plagg was with Adrien when he went to the library to research his group's particle physics presentation. When Chloé was attacked by several berets and a hairdryer, Adrien and Plagg transformed into Cat Noir. They helped Ladybug take down the hairdryer and tried to go after the villain, but he escaped. Instead, Ladybug and Cat Noir went to Le Grand Paris to investigate why the Evillustrator was after Chloé. Ladybug left in an angry huff, leaving Cat Noir behind to guard Chloé. Cat Noir stayed with Chloé until Ladybug called later in the day about the Evillustrator's crush on Marinette. Cat Noir left Chloé in order to guard Marinette on her date with the Evillustrator. The date wasn't successful because Cat Noir was heard when he boarded the Evillustrator's boat. After saving Marinette from the sinking ship, Cat Noir chased after the Evillustrator and went back to Le Grand Paris to save Chloé. Ladybug met them in Chloé's room and together, they took down the Evillustrator. The next day, Plagg went to school with Adrien.
