|“||I don't feel like being a superhero tonight. And I also don't feel like being alone tonight. Would you mind if I hung out here for a little while?||”|
—Cat Noir, "Glaciator"
Adrien Agreste is one of the main protagonists of Miraculous: Tales of Ladybug & Cat Noir. He is a student in Miss Bustier's class at Collège Françoise Dupont in Paris, France. He is also a fashion model for his father's brand. With the Cat Miraculous, when it is inhabited by Plagg, Adrien transforms into the superhero Cat Noir ("Chat Noir" in the French version), gaining the power of bad luck and destruction to stop Hawk Moth and his akumatized villains. He is also the second-in-command of the French Miraculous superhero team.
In "Desperada", Adrien temporarily obtains the Snake Miraculous, which when inhabited by Sass, will be able to transform him into Aspik, gaining the ability to go back in time for a Second Chance.
In "Cat Blanc", in an alternative future, Adrien, conflicted between his loyalty towards his mother and the girl he loved, is akumatized by Hawk Moth into Cat Blanc, a cat-themed supervillain with the power of infinite destruction.
Adrien is a handsome fair-skinned slender teenage boy with brushed-back blond hair that is swept to the right, emerald green eyes, and has a rosy tint on his cheeks, nose, and the tips of his ears. He is about half a head taller than Marinette Dupain-Cheng.
Adrien wears a white button-down shirt with an upturned collar and sleeves rolled up above his elbow, which he keeps unbuttoned. Underneath, he wears a black shirt with five horizontal stripes around the chest which are colored, from top to bottom, yellow, olive green, bright green, dark green, and periwinkle. He wears blue jeans and orange sneakers with white laces and a logo of a black butterfly in a circle on the sides. On the ring finger of his right hand, he wears the Cat Miraculous, which is silver when he's not transformed.
As Cat Noir
Cat Noir has cat eyes with green sclerae, dark green irises and oval pupils. His hair becomes longer and untamed and it covers his normal ears. Cat Noir wears a textured black skin-tight catsuit with metal details. He wears matching gloves that have claws on the fingertips and boots with a hidden wedge, silver toes, and paw-shaped treads. He has a golden bell on his neck, connected to a zipper on the front of his costume, and a long belt that wraps around his waist and hangs out from the back like a tail. He wears black cat ears and a black mask around his eyes. When transformed, his ring turns black and gains a bright green paw print on its face.
As Mister Bug
He wears a skin-tight ladybug patterned suit with black accents on the knees, upper arms, hands and neck. He also has a yo-yo around his waist. Like Cat Noir, his hair becomes longer and untamed, which covers his normal ears.
Aspik wears a green and turquoise skin-tight suit with yellow accents. He wields a lyre as his Miraculous tool.
As Snake Noir
Snake Noir is a hybrid form of Cat Noir and Aspik. He has a black suit with turquoise parts.
As Cat Blanc
Cat Blanc looks like Cat Noir, except that his catsuit is completely white, including the bell and the cat ears. His hair, despite still being longer and untamed, is also white, his skin is pale, and his eyes possess white irises and blue sclera.
Adrien is a dreamer and charismatic, but is also often shy, a bit reserved, and considerably innocent — particularly due to his unfamiliarity to much of the world beyond his father's reach. Even though he is not very openly emotional to most people, he is friendly, empathetic, understanding, supportive and encouraging to others in hard times. His will for exposure, change, and making friends definitely complements his personality, although it is a bit of a struggle for Adrien due to his busy schedule. Because of his innocence and kind heart, Adrien is very willing to give second chances to others that have cruel or mean intentions, like Lila and Chloé, believing that with enough patience and time anyone can change. However, he will defend his friends if matters go out of hand.
Due to his kind heart he can be oblivious at times to the darkness or mischief that are in hearts of others like his father or his cousin Felix.
Adrien's shyer, gentler characteristics can be observed in awkward or uncomfortable situations, or scenarios with particular people. This was shown when he nervously asked Marinette to sign his copy of Jagged Stone's new album, shyly greeted Ladybug in "Simon Says", posed with Marinette as their alter-egos in Clara Nightingale's music video, displayed shyness about going on a date with Kagami alone in "Frozer", and tried to make Marinette more comfortable around him but froze up and instead played a joke during "The Puppeteer 2".
While liking to have fun, Adrien is more serious, obedient, somewhat insecure, and less lively due to his strict upbringing. If something makes him sad, he usually tries to downplay his feelings on it, like his relationship with his father. He has an easier time letting his feelings show to those whom he is close to. However, Adrien will act on impulse if he is emotional enough, like lying to Théo Barbot out of jealousy about his relationship with Ladybug and sneaking out into the night while unhappy on Christmas, missing his mother. He feels that his father is overprotective, causing him to occasionally act rebelliously, like going places with his friends or alone without informing his family and taking things that don't belong to him, though the former case was caused by his father's over-protection.
His desire to be loved makes him vulnerable whenever disappointed by those he cares for, as seen when Ladybug didn't show up for their date in "Glaciator". Family related issues also strike him emotionally, even the simple situation when his father doesn't show up to spend dinner with him. Or when Mayura's deception lead him into trouble, meaning that he follows his heart at the most inconvenient times.
Adrien usually thinks reasonably and will express distress and frustration when someone is being difficult or something is going wrong, especially in Plagg's case. However, according to Gabriel, Adrien is very similar to his mother, describing them as "dramatic" and "headstrong when in comes to other people's safety". He can be rather reckless with or without the mask, insisting on fighting Riposte with a sprained ankle in order to protect his crime-fighting partner. This was seen again to a more dangerous extent, like when he had his ribs broken as a result of his Cataclysm being used against him. On the verge of dying, he insisted on continuing to fight anyway showing his will and determination to help even if restrained. On certain occasions, Adrien (as Cat Noir) can be hasty sometimes, evidently when rushing to face certain akumatized villains without a plan. Due to this rashness, he often needs to be restrained or stopped by Ladybug or Master Fu.
At times, Adrien can be persistent and curious about his Miraculous powers or when wanting to figure something out, as seen when he continuously bribed Plagg with cheese until he spilled the truth about what Ladybug was hiding from him. This trait is highly apparent in his romantic pursuit of her, to the point where both Marinette (referring to Cat Noir) and Kagami believe that he is stubborn. However, like Alya Césaire, he places extreme values on the mutual trust he has with Ladybug, respecting her decision to keep her identity secret and eventually her secrets with the Guardian. According to Ladybug, Cat Noir does annoy her a lot, but he has never lied to her. Per her wishes, he is secretive to others about his personal life such as his love towards her, partially telling his true feelings to her aforementioned friends.
As Cat Noir, Adrien has the freedom to act however he desires outside of his normal life, letting his wilder side come out.  More optimistic and open, he says whatever comes to his mind and has a habit of cracking cat-related jokes and puns. As he said in "Plagg", being Cat Noir is the only time Adrien can be himself. Much of his exaggerated personality, especially his flirtatious behaviour with Ladybug, stems from entertainment such as anime, television, and movies due to his lack of experience with people his age beyond Chloé. According to Plagg, Adrien often takes after him and is one of his most irresponsible owners in 5000 years, though the latter might be an exaggeration since he also considered him the best "Cat Noir". It is rare for Cat Noir to reveal his vulnerable side, but it does come through at times. Examples of this are when he quietly comments that not all parents are loving, tries in vain to tell Ladybug about his love for her before their transformations wore off, and opens up to Marinette about his struggles in the love department.
Since he became Cat Noir, like Marinette, Adrien has grown in confidence and developed characteristically. This can be seen during the time he lashed out at his father and courageously asked Nathalie if he could bring his friends with him to the wax museum. In his attempts to get Ladybug's attention, as well as interacting with certain other people, he acts cocky and brags, liking to boast about himself in a comedic way. In "Cat Noir as seen by Marinette", was described by Ladybug in the same way. However, Cat Noir very occasionally shows insecurity and compares his abilities to Ladybug or their new partners.
He displayed his biggest sense of insecurity when he failed to save those he cares about. In "Desperada", he briefly expressed his intense frustration and sadness to Ladybug about repeatedly not being able to save her and not knowing what to do anymore. His romantic feelings towards her stemmed this situation and distracted him from fighting the villain at hand, observable in other fights and episodes as well. It often sparks his instincts to protect Ladybug before himself, as well.
Despite all these traits, Adrien's change to his superhero status doesn't diminish his kindness and concern for others, among his other personality traits, such as his reasonable character and reckless behavior. He usually tries to persuade the supervillains to calm down and stop their rampage before fighting them, when able to do so. While more prone to goofing off, Cat Noir gets serious when it is a lethal situation. He understands that it takes more than just superpowers to be a hero or useful, using his wits to help Ladybug out of a tight spot even without his powers. He also knows how to cheer up his partner during their hardest times and encourages her to try to fight again. Deeply loyal and determined to help others and save the day, he really cherishes being uninhibited by his civilian life as a superhero.
Cat Noir is welcoming and friendly when it comes to accepting new additions to the team, having open arms for Lila in "Volpina" and Rena Rouge in "Sapotis". He is also open to accepting help from others like Alix and Nathaniel during battles, as shown during the time he was reversed from "puss to wuss", becoming a complete coward, contrasting to his brave and confident nature. Like Ladybug, he is good at providing advice to others when they need it.  As Cat Noir, Adrien has the people's loyalty, respect, trust, and help when he needs it.
Through spending time with his other allies, Cat Noir like Ladybug; also values their support and help. Thanks to his time as his alter ego and daringly wanting to see outside world, Adrien got to experience something his father may have forgetten the love of others. Starting to feel that Ladybug and others are like his second family. As well as valuing the support, companionship and help of his friends.
As Mister Bug, Adrien retains most of his personality as Cat Noir like his hastiness and his confidence in his abilities. However, according to Lady Noir, he has lost some of his sense of humor, getting a taste of Ladybug's careful side and creative thinking.
As Aspik, Adrien retains more of his personality as a civilian rather than as Cat Noir. However, despite being still trustworthy and faithful, but was unfocused as his crush on Ladybug prevented him from doing a good job fighting Desperada. Desperate to impress her as Adrien, he disregards the villain's movements and keeps using his power to go back in time to try to prevent Ladybug from being captured. Eventually, he comes to conclusion he cannot be of any help to her as Aspik and returns the Snake Miraculous to Ladybug understanding that what he was doing brought more harm than good.
As Cat Blanc, he retains most of his personality as Cat Noir, but in a more twisted way. His flirtatious behavior is used as a facade to get close to his opponents so he can attack them. His love for Ladybug had become more obsessive and, while still showing to care for her, he still tries to get her Miraculous, even if that means destroying her. His temper becomes even more intense, as he tried to destroy the whole galaxy, if not more, in anger for Ladybug not giving him her Miraculous. Also, he started to act like his father when he was Hawk Moth, having his heart go twisted by sadness, despair, and was desperate to get what he wanted despite the price.
Also similar like him, Adrien seemed to overlook easier solutions to fixing a problem as he tried to use the Ultimate Power to change everything back but he forgot that Ladybug's powers can fix everything without putting the universe at risk.
As a civilian
Studious and formerly home-schooled, Adrien is the top student in his class, his lowest grade being an A- in Math. He is especially good at physics. Having many extra lessons, Adrien can speak fluent Chinese and Japanese, and can even understand Morse code. He is also very skilled at piano playing and enjoys sharing musical joy with others.
Adrien is able to fight on equal grounds with his fencing teacher and fend off most of his students effortlessly with the exception of Kagami, showing great reflexes and skill for offensive or defensive movements. Other than fencing, Adrien does Karate and Kung Fu, which enables him to fight in hand-to-hand combat and briefly fight his akuma-controlled bodyguard. Furthermore, Adrien takes basketball lessons. He took interest in video games as well, being able to beat Max Kanté in Ultimate Mecha Strike III and achieve one of the top scores in the entire school (despite being surpassed by Marinette later). It is shown in "Mr. Pigeon" that he can whistle.
Like Marinette to a possible lesser extent Adrien has great stamina and endurance as he was able to outrun a fan mob and was able to handle to both the physical and mental strain of wielding two Miraculous together without struggle.
Though often looked down compared to Ladybug and being more simple, straightforward-minded, Adrien is very intelligent and capable. He is able to look for loopholes in his father's rules, which his friends considered "sneaky". Though restless and reckless, Cat Noir is observant, noticing where the akumas are hidden several times and finding ways to save his Miraculous even when captured. He tricked Ladybug (and indirectly the suspicious Hawk Moth) in believing he wasn't Adrien.
He further demonstrated his wits in his use with the Snake Miraculous as Snake Noir. He also suspected that Marinette was Ladybug after discovering that her kwami was in school and considering her regular disappearances (although he was tricked by her in the end).
From his lessons with Master Fu, Adrien has received the same knowledge about the history of the kwamis and the Miraculouses as Marinette, though likely less, as he wasn't prepared to become a guardian.
As Cat Noir
Cat Noir has enhanced skills such as speed, agility, and near-invulnerability. He is fast enough to outrun a pair of panthers, meaning he is capable of running at least between 35-50 mph. His increased strength allows him to do things such as being able over shoulder throw his own bodyguard into an elevator, round house kick, punch and stomp vending machines and kitchen appliances with just one strike. His increased stamina and endurance allows him to survive being flung by Gigantitan and take a crash landing through Andre's ice cream stand without being dazed or injuried. He also has good hand-to-hand combat skills when needed. Even out of "Aqua Mode" Cat Noir is a good swimmer. He can even handle temperatures as severe as absolute 0.
Like a cat, Cat Noir has enhanced senses such as hearing, smell, night vision, and has super stealth, which he sometimes used to find opponents. Also like a cat, Cat Noir can use his claws to climb up surfaces or use them to cut through things.
Cat Noir uses his staff efficiently, wielding it as a sword, throwing it with great precision and having it be deflected back to him. He is able to spin it at high speeds to form a shield or take advantage of its duplication and length-changing features. To travel long distances, he uses his staff and its variety in length to vault over obstacles. In and out of "Aqua Mode", he can also use his staff as a breathing apparatus for those who can't breathe underwater.
His special power, Cataclysm, allows him to negatively affect and essentially destroy anything that he touches with his ring hand. While it is usually used for object destruction, it can be used for a variety of different effects, for example, causing a bus' controls to go haywire and creating a platform in a structure. However, like other superheroes, using Cataclysm drains his Miraculous' power, causing him to revert back to Adrien five minutes afterwards.
When accessing his aqua powers, Cat Noir has the ability to breathe underwater and enhanced swimming capabilities.
When accessing his ice powers, Cat Noir has the ability to handle extremely low temperatures, as well as move freely and quickly on the ice.
As Mister Bug
He has the same abilities as Ladybug: enhanced skills like speed, agility, and strength, and near invulnerability to physical damage.
Like Ladybug, Mister Bug can wield his yo-yo remarkably well, like using it as a grappling hook, a rope to restrain others, a projectile, and a shield if he spins it fast enough. After an evil akuma is released from its corrupted object, he can open his yo-yo, throw it to grab it, and remove the energy-charged it with, releasing it as a normal butterfly.
Along with his special power, Lucky Charm, creates an object that helps him to achieve his objective, it often being to stop a villain. Though usually confused at first, his cleverness help enable him to perceive where the object can be used to help him achieve his goal. However, Lucky Charm drains his power and causing him to revert back to Adrien shortly afterward, so he has to use it wisely. Once the villain is dealt with, Mister Bug can throw his Lucky Charm object into the air and use the Miraculous Mister Bug which will make it revert back to energy and fix all of the damage done since the villain appeared.
Like Viperion, Aspik has much more enhanced skills, such as speed, agility, and strength, and he is almost invulnerable to physical damage. Like a snake, he also has enhanced senses like hearing and smell as well as infrared vision and possibly the ability to feel vibrations but it is yet to be seen.
His special power, Second Chance, allows him to reverse time and change the outcome of an event, in which the power activates by sliding his finger on his Miraculous.
As Snake Noir
As Cat Blanc
As Cat Blanc, he possesses power of infinite destruction. He can use a super enhanced version of the Cataclysm, known as the Mega Cataclysm. He can also release his destructive power at long range, as a blast or as a ray. He is capable of unleashing destructive energy that could potentially destroy whole galaxies in a single strike. He can use his power an infinite number of times without his transformation dropping.
= Gender Unknown
- Emilie Agreste mysteriously disappeared before the events of Season 1. In "Style Queen" and "Queen Wasp", it was revealed that she is underneath the Agreste Mansion in the same room seen in "Gorizilla", inside something resembling a coffin, in which she appears to be in a comatose state.
- In “Félix”, it is said that Gabriel did not let Adrien go to Amelie's husband's funeral.

- The character of Adrien was created around 2012.
- The earliest known appearance of Cat Noir was on the fake cover of Issue #12 of The Mini Menace Ladybug.
- In Polish, the pronunciation of Adrien's surname "Agreste" means gooseberry.
- Fans originally called him Félix, after a famous cartoon cat. For some time, this name appeared on the original French version of Zagtoon's official website, but later disappeared with newer, equally reliable sources calling him "Adrien."
- Adrien's appearance changed immensely from Félix's design (seen in the Ladybug PV) to his own design. Félix's design included more formal clothing with black and gray colors, desaturated green eyes, and a tidier hairstyle. As Cat Noir, Félix wears higher boots and doesn't have a staff for a weapon.
- Their personalities are also different. Félix is less social, not openly friendly, and unkind to Marinette.
- Unlike Félix, Adrien's ring can come off anytime. This is seen in "Lady Wifi" when he, as Cat Noir, gets locked into a freezer and the impact causes his ring to fall off his finger, which makes him revert back to normal.
- Because Félix was Cat Noir in the Ladybug PV, Adrien was never seen in 2D form until the Miraculous: Tales from Paris webisodes. He will be seen again in 2D in the Miraculous Ladybug OVA, as Adrien is confirmed to still be Cat Noir instead of Félix.
- The French name "Adrien" comes from the Roman cognomen "Hadrianus," which means "from Hadria." In the days of the Roman Empire, Hadria was a town in northern Italy and the namesake of the Adriatic Sea. The Adriatic Sea is known for the dark-colored sand on its beaches, and for this reason, the name is also commonly translated as "dark one."
- In "Copycat", Adrien's phone number is shown to be +33635124.
- As he says in "Pixelator", he got to go to his first concert.
- According to Gabriel Agreste's voice actor, Adrien is not allowed to play Pokémon Go.
- The name "Chat Noir" is French for "Black Cat." Some sources have called him "Black Cat" instead of Chat Noir or Cat Noir.
- In the Korean, Hebrew and Serbian versions, Adrien's superhero name is "Black Cat."
- In the Russian version, Adrien's superhero name is "Super Cat."
- Cat Noir's legacy is as old as ancient China, as revealed in "Volpina".
- His responsibilities as a superhero not only include fighting akumatized villains, but also patrolling among many other things.
- Adrien doesn't appear to have as many issues juggling his normal life with his superhero work as Marinette does. However, he does struggle on occasion, as seen in "Princess Fragrance" when he misses his chemistry class, in "Simon Says" and "Gorizilla", where he had to be in two places at the same time, and in "Backwarder" where he had to hurry back to the train before his father noticed he was gone.
- This might be because Nathalie arranges most of his activities (extra studying, photo shoots, fencing, Chinese and piano lessons, etc), unlike Ladybug who arranges her things alone, but it is still suffocated.
- Cat Noir has been turned evil several times so far, having fallen under the influence of Dark Cupid's hate arrows, ending up under the control of The Puppeteer, being affected by Princess Fragrance's perfume, becoming controlled by Despair Bear, then being affected by Zombizou's kiss and lastly being affected by Malediktator's declaration bubbles.
- Unlike the others, Malediktator didn't use Cat Noir to fight against Ladybug.
- As Cat Noir and himself, Adrien has been affected the most times by akumatized villains out of the French Miraculous superhero team with a total of 18 times.
- According to Thomas Astruc in a joking matter, Cat Noir's suit is made of "boyfriend material".
- The suit is not made of leather but it is the closest material.
- The ears are made of the same material as the rest of the suit.
- The bell functions as a zipper and was added "because it looks cute."
- The bell on Cat Noir's suit is a reference to a domestic kitten, conveying his inner desire for a loving home.
- In "The Collector" reveals that Cat Noir’s tail is detachable.
- Cat Noir's cat ears and tail are clearly fake. However, they respond to his mood and enhanced senses.
- During "Dark Cupid", when Cat Noir isn't able to confess to Ladybug because their transformations are about to run out, his ears move down.
- In "Animan", his cat ears move when he hears Animan coming.
- Again in "Troublemaker", where he heard the villain's incoming attack.
- Cat Noir has done many catlike actions, caressing his tail after Ladybug pulled it in "Stormy Weather", Ladybug scratching his chin in "Animan", cleaning himself by licking water off in "Princess Fragrance", purring in "Prime Queen", as well as growling at the villain, Audrey petting and cuddling him, licking his paw and chasing the toilet paper roll and the light of Ladybug's laser pointer, playing with Audrey's necklace and taking naps in "Malediktator". In other episodes he runs on all fours like a cat.
- As well as use his claws to climb up surfaces but unlike a real cat he can use them to cut through things.
- In the French version of "Copycat", Cat Noir calls Ladybug "Buginette" (in French, adding "-nette" to the end of a word is a way of showing affection). In the English version, he calls her "Bugaboo."
- In the French and Korean versions of "The Evillustrator", he called Marinette "Princess". In the English version, he calls her "little lady".
- According to Marinette in "Gigantitan", he always leaves his personal items in the car when he's on a photo shoot.
- In "Gorizilla," Adrien's email address is revealed to be firstname.lastname@example.org.
- The first time he went to the theaters with a friend was with Marinette in "Gorizilla".
- In "Syren", it is revealed that Adrien has Ladybug and Cat Noir figurines.
- He also says he has always wanted a goldfish.
- In "Sandboy", as himself, Adrien's greatest fear is being trapped alone, and as Cat Noir, his greatest fear is Ladybug hating him.
- As in "Weredad", Adrien as Cat Noir reveals that this is the first time a girl admits being in love with him.
- Thomas revealed on Twitter that Adrien and Marinette will be seen as a "real couple" at some point in the show.
- In "Gorizilla", she was referred to as Adrien's girlfriend, though in that case, it was due to public misperception.
