Beware of spoilers!
Adrien and Marinette's class
- A Day in the Limelight:
- Their individual akumatization episodes serve as this; we normally learn a little about their family lives, personalities, or motivations so the akumatization is more understandable.
- Starting in Season 2, we see them undergo Character Development and reveal more about themselves beyond their akumatizations; either they help Marinette and Adrien out with their civilian problems, or they assist Ladybug and Cat Noir because they are in/directly involved with the episodes Akuma.
- Several of them get another episode where they're gifted a Miraculous for a day.
- Disney Death:
- In "Timebreaker", most of the class become victims of Timebreaker as the result of stealing their life energy, which made them freeze then fade from existence. Luckily, after she and Ladybug went back to the past, all of them are back.
- In "Cat Blanc", all of them including the other Parisians become ashen statues as the result of Cat Blanc's Mega Cataclysm in a Bad Future. Thanks to Bunnyx's help, Ladybug was able to fix the timeline, which prevents those events, including Cat Noir's akumatization, to ever happen.
- Heroic Bystander: As of season two, the class as a whole is more active against akumas. Special mentions go to Chloé and Max, who directly save Ladybug and Cat Noir's lives. Season 3 takes this further by having several of them graduate from bystanders to full fledged heroes.
- Opposites Attract: Other than Marinette/Alya and Adrien/Nino, each best friend pair in the class is made up of students who contrast in looks or personality, such as Light Feminine and Dark Feminine Rose and Juleka or Ivan and Mylène's Brooding Boy, Gentle Girl dynamic.
- Shipper on Deck: Most of the girls in the class are 100% rooting for Marinette's crush on Adrien.
- Teens Are Short: Most of them are shorter than the series' average adult. The exception is Ivan, lampshaded in "Reflekta" when the photographer doesn't know where to put him because he's so huge.
- Took a Level in Badass: From Season 3 onward, Ladybug begins choosing them one by one to wield the Zodiac Miraculouses, in addition to Kagami and Luka.
- True Companions: Barring Chloé, the class as a whole is a pretty united bunch.
- Unwitting Muggle Friend: Most of them are on good terms with Marinette and Adrien, but nobody seems to have any idea that the two are Ladybug and Cat Noir.
- Wacky Homeroom: The class is relatively close and provides a sense of normalcy to Marinette and Adrien's lives. Each of the students has a distinct design and personality (some based on stereotypes such as Alpha Bitch, Nerd, etc.).
- Weirdness Magnet: The school as a whole seems to be a frequent target for akuma. Besides the main class, the students' family members and other staff and students at the school have also been targeted. Turns out that Hawk Moth is counting on this, due to Chloé's poor attitude being extremely liable to upset people and make them vulnerable to akumatization. Lila also helps a lot, especially by the third season.
Akumatized forms: Vanisher, Miraculer
A soft-spoken classmate of Adrien and Marinette, and Chloé's "best friend". Sometimes she's Chloé's aider and abetter in wicked schemes, other times she's the first and worst victim of Chloé's meanness.
- All Girls Want Bad Boys: A possible same-sex version where "Sole Crusher" sees her clinging to Zoé's arm (even closing her eyes happily) and asking if Sabrina can do her homework right after Chloé impelled Zoé to insult Marinette. It might have just been Sabrina assuming that's what Chloé would want her to do, but considering her relationship with Chloé, one could also interpret it as Sabrina actually liking someone being a public and haughty jerk.
- Ambiguously Bi: She has a toxic yet very close relationship with Chloé, yet shows interest in an American boy during the New York special.
- Beta Bitch: To Chloé's Alpha Bitch. Whenever Chloé comes up with one of her mean deeds, Sabrina is usually the one who does the dirty work while Chloé paints her nails or fixes her hairdo.
- Clingy Jealous Girl: Platonic version. She's a very clingy friend and tends to seethe or despair when the object of her single-minded affection (usually Chloé, but on occasion Marinette) either stops hanging out with her or has other, non-Sabrina related things to do.
- Daddy's Girl: Sabrina has a close relationship with her father.
- Depending on the Writer: In some episodes, Sabrina comes off as an extremely docile but nice girl, while in others she is shown to have a mean streak.
- Distracted by the Luxury: With the right impetus, she's willing to call Chloé out for her exploitative behaviour now and again... but she's also susceptible to flattery and luxurious gifts.
- The Dog Bites Back:
- In "Evillustrator", after some encouragement from Marinette, Sabrina finally confronts Chloé about how badly she treats her. Sadly, old habits are hard to break, and Sabrina ends up forgiving Chloé.
- In "Antibug", Chloé spurns Sabrina when she accidentally embarrasses her in front of Jagged Stone, pretending Sabrina is invisible. This allows Hawk Moth to corrupt Sabrina and turn her into the Vanisher, whereupon Sabrina uses her new power to torment Chloé.
- Dramatic Irony: Part of the reason Sabrina is so loyal to Chloé and lets her treat her as a slave is because without Chloé she would not have any other friends. But it's clear to the viewer it's the other way around, and if their friendship ends Chloé would be the one without friends and Sabrina would probably be able to befriend her classmates.
- Extreme Doormat: She has been doing Chloé's homework for her, and generally obeying her every order, since they were in elementary school.
- Foil: To Adrien — Both are the only two individuals who consider Chloé a friend among their peers, but act quite passively in regards to her mean behavior, fearing the loss of the only friendship they've ever had. Adrien is practically doted on by Chloé because of her crush on him, thus acting as her Morality Pet, and after some Character Development on his part, he begins to call her out on her behavior. Sabrina is more like Chloé's servant than friend, as the latter hardly ever shows her loyal "friend" any kindness outside of the rare occasion, and while Sabrina has hurt Chloé in retaliation for her cruelty, she goes right back to being Chloé's doormat "friend".
- Four Eyes, Zero Soul: Downplayed. She wears glasses and, depending on the episode, can be a Nice Girl or a shameless Beta Bitch.
- Friendship Trinket: A brooch Chloé gave her means the world to her, and when Chloé tells her their friendship is over, it's what the akuma possesses to turn her into Vanisher.
- Ink-Suit Actor: Her resemblance to her first English voice actress Marieve Herington is quite striking.
- Innocent Beta Bitch: In the earlier episodes, she is a Nice Girl who gets disrespected and bossed around by Chloé.
- Meganekko: To emphasize her quietness and intelligence, she wears glasses.
- Nerd: Subverted, although she has the look and outfit of one, she's the Beta Bitch. Between her and Chloé, however, Sabrina is by far the more book-smart and diligent one.
- Never Bareheaded: Always a white hairband in her hair.
- Only Friend: Is this for Chloé.
- Punny Name: The name Sabrina Raincomprix is pronounced similarly to the French "Sabri n'a rien compris", or "Sabri didn't understand anything", alluding to how Chloé manipulates her.
- The Resenter: For all her slavish devotion to Chloé, it's implied that, deep down, she feels this way about their unequal friendship. Notably, when Marinette stands up to Chloé and tells Sabrina that she could do better, Sabrina immediately christens Marinette her new best friend and is ecstatic about no longer having to deal with Chloé's freeloading. She even outright accuses Chloé of treating her like a slave, in Marinette's words, despite the latter never actually saying that...
- Satellite Character: Sabrina is pretty much completely defined by her relationship with Chloé, to the point that both of her akumatizations involve them falling out in some way.
- Shipper on Deck: Sabrina supports Chloé's affections towards Adrien.
- Smart People Wear Glasses: Sabrina wears glasses, and between her and Chloé, she's the academically smarter.
- Tights Under Shorts: Wears black tights under blue jean shorts.
- Took a Level in Jerkass: Earlier in the series she was a mostly Nice Girl who simply went along with Chloé's schemes because she was her Only Friend and likely out of fear of her as well, but later episodes depict her as willingly going along with them and behaving more hostilely towards others.
- Undying Loyalty: Deconstructed. Out of all their classmates, Sabrina is staunchly loyal to Chloé. However, their relationship is proven to be nothing but unhealthy, as Sabrina is shown to be an Extreme Doormat because of this and going along with whatever selfish scheme or cruel action Chloé does...which means that if Chloé ever does end their friendship, Sabrina won't have any other friends because of her loyalty to Chloé.
- Yes-Man: Sabrina basically agrees with everything Chloé says.
Akumatized form: Stoneheart
Ivan is a big guy who seems tough and scary, but actually has trouble expressing his feelings. He is in a relationship with Mylène.
- Affectionate Nickname: Mylène calls him "Teddy Bear".
- All Drummers Are Animals: Averted. Ivan is the drummer for Kitty Section, but he's a Gentle Giant.
- Amazon Chaser: Implied. The translation for his love letter to Mylène in "Stoneheart" had these specific lines in them:"Stronger than oak, for others you fight..."
- Big Ol' Eyebrows: Ivan has the biggest eyebrows of his peers.
- Bruiser with a Soft Center: He comes off as the typical tough guy, but is kind and gentle with Mylène. When the Horrificator attacks, he's shown protecting and comforting his classmates from the akuma. Hawk Moth even lampshades how sensitive he actually is in the origins episode.
- Cannot Spit It Out: In the origins episode, he gets akumatized because he has trouble confessing his feelings for Mylène.
- Dreadful Musician: His attempt to confess to Mylène through song fails because his singing comes across as unintelligible screaming. However, in "Captain Hardrock", he proves to be a reasonably skilled drummer.
- Dark Is Not Evil: Dresses in black and is almost always a Perpetual Frowner, but is one of the nicest in the class.
- Face of a Thug: He generally looks like a typical tough guy, is a Perpetual Frowner, has dyed hair and usually wears a black shirt, but he is actually a fairly gentle and easygoing person most of the time.
- Gentle Giant: He's by far the largest in the class, but is usually quiet and gentle unless provoked. In his own webisode Marinette even calls him one.
- Huge Guy, Tiny Girl: Mylène is practically half Ivan's height.
- Multicolored Hair: His hair black, except for a tuft of long, dyed blond hair above his forehead.
- Nice Guy: He may look intimidating, but he has a tender heart.
- Official Couple: With Mylène as of "Stoneheart".
- Opposites Attract: He's a surly Perpetual Frowner while Mylène is gentle and caring.
- Perpetual Frowner: He seems to be always scowling, except around Mylène.
- Real Men Wear Pink: You'd expect his sweet girlfriend to be the one with the pink backpack, and yet, somehow it works for him.
- Relationship Upgrade: At the end of "Stoneheart", him and Mylène.
- Youthful Freckles: He has some freckles on his nose and cheeks, emphasizing that, despite his height, Ivan is still a teenager.
Akumatized form: Evillustrator
A shy artist who harbors a crush on Marinette (and in season 2, on Ladybug). However, he becomes close friends with Marc Anciel at the end of "Reverser".
- Ambiguously Bi:
- Although he has a crush on Marinette (and later on Ladybug), by the end of "Reverser", he becomes friends with Marc Anciel... who's easily flustered in his presence, and whom he seems to reciprocate the feelings.
- He can be seen alongside Marc in "Frozer" (when Adrien is looking the nearby couples in the school) and "Mayura" (during the picnic at the end of the episode).
- Ambiguously Jewish: Going by his surname and his noticeable absence from the Christmas special (most of the rest of the class showing up at the Agreste mansion for Christmas dinner).
- Be Careful What You Wish For: He dreams of becoming a superhero who can save Marinette from the many villains plaguing Paris. His akuma form's appearance and powers are identical to the superhero persona he made for himself.
- Berserk Button: Being mocked over his crush or getting his romantic hopes up (Chloé mocking his crush on Marinette got him akumatized in the first place, Marinette pretending to go on a date with him in "Evillustrator," and believing Marc and Marinette led him to think Ladybug liked him in "Reverser") tends to turn the normally nice, shy, quiet Nathaniel real mean real quick.
- Birds of a Feather: He and Marc are both nice, shy, quiet, introverted artists.
- A Birthday, Not a Break: Like Alix, he gets akumatized on his birthday.
- Even the Guys Want Him: Fellow art classmate Marc has feelings for him.
- Fan Art: Makes this of himself and Marinette.
- Fiery Redhead: Inverted. His hair is a deep red, but he's one of the quietest and shyest characters.
- Her Code Name Was "Mary Sue": His comics have shades of this, given that they center on the exploits of Ladybug (who he is implied to have a crush on) and his Self-Insert superhero Mightillustrator.
- Hopeless Suitor: He's in love with Marinette. Needless to say, she doesn't reciprocate. The ending of "Evillustrator" and "Reverser" imply that his affections have moved to Ladybug, who is...still Marinette and still unlikely to return his feelings.
- In-Universe Nickname: "Nath", as shown in "Reverser".
- Jerkass Ball: In "Reverser", Nathaniel reacts very poorly when he finds out the "mysterious writer" he was set to meet was not the person he expected, mistaking the situation for a prank at his expense. He is usually a nice boy, even other times when people mocked him, he simply left rather than lash out at the other person. Though he does have a track record of reacting badly when he thinks someone is mocking his crush (Chloé) or getting his romantic hopes up (Marinette), as seen in "Evillustrator."
- Meaningful Name: The "Kurtz-" part of his last name is a Jewish surname meaning "short in height" — which is fitting since he's tinier than most of his classmates.
- Mr. Imagination: He's rather dreamy, and fantasizes about being a superhero and saving a swooning Marinette from villains.
- Named After Somebody Famous: His last name is a homage to Jack Kirby (born Jacob Kurtzberg), innovative comic book artist who created various characters for Marvel and DC.
- Opposites Attract: A platonic version. Since they both love art, Alix is one of his closest friends. But she prefers street art while comics are more his taste.
- Peek-a-Bangs: His hair covers his right eye and is of the "shy and demure" variety.
- Pretty Boy: Not as dashing as Adrien, but he still has rather fine facial features.
- The Quiet One: Shares this role with Juleka. Nathaniel doesn't speak much, preferring to express himself through art.
- Those Two Guys: With Marc.
- Shrinking Violet: And like most male examples is treated as a bit of a Butt-Monkey, which is what leads him into getting akumatized.
- Shout-Out: The logo on his shirt is based on that of the band Magma, which creator Thomas Astruc and art director Nathanaël Bronn are fans of.
- Tiny School Boy: He's noticeably tinier than the majority of his classmates, to the point that Miss Mendeleiev is able to lift him with one hand.
- Twofer Token Minority: Jewish + Ambiguously Bi.
- Tuckerization: His name is an homage to Nathanaël Bronn, chief art director of the show.
- Wrong Genre Savvy: Considers himself the real hero while Chloé is the villain. He's wrong on both counts.
Akumatized form: Stormy Weather
One of the finalists for KIDZ+'s Miss Weather Forecaster contest. She is a student in Ms. Mendeleiev's class.
- Fangirl: In some of her recurring appearances, she is seen fangirling over Adrien.
- Girlish Pigtails: She's a girly teenager, so these are present in her design.
- Hopeless Suitor: She has a crush and/or attraction to Adrien, but given his intense interest in Ladybug, the feelings won't be returned.
- Parasol of Prettiness: She carries a parasol to the contest, to complement her image as a weather girl.
- Pride: Aurore is quite prideful and because of her arrogance she becomes upset when Mireille wins against her.
- Punny Name: "Aurore Beauréal" is a pun on the aurora borealis, an electromagnetic phenomenon that causes waves of colorful light to appear in the sky.
- Recurring Extra: Less so than Théo, but in later episodes Aurore sometimes appears as a student at Marinette and Adrien's school.
- Screw This, I'm Outta Here!: In "Stormy Weather 2", Chloé is picking on her when Marinette and co. rush to the rescue. Aurore promptly takes the opportunity to "nope" right out of the conversation.
- She's Got Legs: Thanks to her rather short blue dress, Aurore really shows off her long legs.
- Sore Loser: Downplayed. Aurore is visibly upset over losing the contest, but she just runs off the set and rants to herself rather than get violent or snippy to Mireille.
- Throw the Dog a Bone: "Ikari Gozen" has her and Mireille host a show together.
One of the finalists for and winner of the KIDZ+'s Miss Weather Forecaster contest. She is a student in Ms. Mendeleiev's class.
- Ambiguously Brown: She appears to be of Asian descent.
- Fangirl: Yet another member of Adrien's fanclub. She's the one hugging Adrien's new poster in Dark Cupid.
- Hopeless Suitor: Like Aurore, she has a crush and/or attraction on Adrien, but it obviously won't be reciprocated.
- Recurring Extra: Like her classmate Aurore, Mireille is often used as filler in crowd scenes.
- You Gotta Have Blue Hair: She has dark blue hair. If she didn't dye it, it's probably a case of Hair Color Dissonance.
Akumatized form: Magician of Misfortune
A student in Ms. Mendeleiev's class.
- Loony Fan: Part of the mob following Adrien everywhere in the beginning of "Gorizilla".
- Noodle Incident: At some point before "Princess Fragrance", he was akumatized and wanted to make the Eiffel Tower disappear.
- Recurring Extra: Jean's character model is often used as a background character.
- Suddenly Voiced: After having no lines for a season and a half, he finally speaks in "Gorizilla".
Akumatized form: Reverser
An aspiring and shy writer who joins the school's Art Class. He seemingly has feelings for fellow art classmate Nathaniel, which he seems to reciprocate after the events of "Reverser".
- Birds of a Feather: He and Nath are both kind, shy, quiet and introverted artists.
- Break the Cutie: After Nathaniel accused him of pulling a joke on him and ripped apart his notebook out of anger, he couldn't do anything but kneeling and crying over its remains. The look on his face is just heartwrenching.
- Cannot Spit It Out: He greatly admires Nathaniel's art (and probably Nath himself), but is too nervous to tell him so.
- Early-Bird Cameo: Made one in "Frightningale", two episodes before his debut.
- Fingerless Gloves: He wears a pair of black ones.
- Idiot Hair: The hair at the back of his head sticks up in all directions. While he is not stupid, he can be a bit clumsy.
- In the Hood: He wears a red hoodie.
- Nice Guy: He is generally polite and friendly, even if he is very timid.
- Possession Sue: In-Universe; given his fondness towards Nathaniel, the story he writes where Ladybug expresses her feelings for Nathaniel's fictional alter-ego comes off as this.
- Punny Name: "Marc Anciel" sounds like "arc-en-ciel", which is French for "rainbow". Fittingly, he wears a rainbow-colored t-shirt.
- Queer Colors: He has a rainbow-colored shirt and blushes around Nathaniel.
- Rainbow Motif: He's LGBTQ+, wears a rainbow t-shirt and his name is a pun on "arc-en-ciel", which is French for "rainbow". This is especially appropriate in-contrast to his akumatized form Reverser, who is entirely black and white.
- Shrinking Violet: He is painfully shy and insecure about his writing skills.
- Straight Gay: Wears a rainbow-colored T-shirt, his shy demeanor towards Nathaniel has romantic undertones and he is based on Hope Morphin, a bisexual and genderfluid friend of Thomas Astruc's, Feri Gonzàles later confirmed on her Twitter account that Marc is indeed LGBTQ+ and has a fondness towards Nathaniel. Yet, aside from his androgynous appearance, he doesn't display any camp mannerisms.
- Those Two Guys: With Nathaniel.
Miss Caline Bustier
Akumatized form: Zombizou
A teacher at Marinette and Adrien's school; she teaches literature and is the kids' homeroom adviser.
- All There in the Script: Her first name is Caline, not that this is ever said onscreen.
- Badass Teacher: The only person in the show to resist akumatization, at least at first. Even when it does infect her, she manages to briefly resist being evilized. While she does fall, it's still more success than any other akuma victim has ever had.
- Babies Ever After: She is revealed to be expecting a child in the New York special.
- A Birthday, Not a Break: She gets akumatized on her birthday.
- Characterization Marches On: In early season one, she was as quick to show no sympathy and dole out punishments as any other teacher (usually trips to the principal's office). By Season 2, she's a Nice Girl and Cool Teacher.
- Cool Teacher: All her students adore her, and have nothing but good things to say about her. Even Chloé feels the same, even if she doesn't show it in public.
- Gotta Get Your Head Together: Assumes this stance when fighting off Hawk Moth's influence.
- Heroic Sacrifice: In protecting Marinette from an akuma, she herself becomes infected.
- Heroic Willpower: Caline initially manages to fight off the akuma infecting her. While she does eventually succumb to its influence, no one has ever even partially resisted an akuma before, a testament to just how nice a person she is.
- Horrible Judge of Character: Her attempt to inspire the class to heroism uses Lila as an example.
- Hot Teacher: It's downplayed, but she is considerably physically attractive with a kind, but firm personality...and it's probably not a coincidence her akumatized form is basically an Attractive Zombie that spreads kisses all over the place.
- Mama Bear:
- A pacifistic example. If a villain or another threat appears, Caline gets nervous and will suggest to her students that they hide or leave if it becomes potentially dangerous. It gets played completely straight in "Zombizou", when she tries to physically fight off an akuma to keep it away from Marinette.
- In a Freeze-Frame Bonus, Miss Bustier can be seen protecting Nino, Sabrina and Nathaniel from Stoneheart in the second Origins Episode.
- Meaningful Name: Her first name Caline means "cuddly" in French, and her last name is the name of a piece of lingerie. Rather fitting for a Friend to All Living Things Hot Teacher.
- My God, What Have I Done?: Once she turns back, she's distressed that she hurt people and calls herself "terrible". Ladybug comforts her by telling her that the blame rightly lies on Hawk Moth.
- Nice Girl: Caline is pleasant and instructive. She is kind to her students, but stern with them if they misbehave, and she will send them to Mr. Damocles' office if she thinks it's necessary. Caline also encourages her students to be nice to one another in part because it's the moral thing to do but also to protect them from being victim to akumas.
- "Not Important to This Episode" Camp: She misses out on the New York special because she's pregnant.
- The Pollyanna: Rather than being offended or angry when Chloé defaces Marinettes birthday gift to her, she instead considers it a gift from both of them and optimistically calms an enraged Marinette down, preventing her from being akumatized in the process. She is so overwhelmingly positive, she only becomes akumatized by the akuma that was meant for Marinette when she tried to swat it away, the fear of her student's safety being the emotion it becomes attracted to, and was even able to briefly fight off the akumatization. The only other person in the show who forced an akumatization-in-progress to stop is, suprisingly, Chloé.
- Properly Paranoid: She tries to teach her students to be kind and positive to protect them from akumas. Doing so kept Marinette from falling victim to one...unfortunately, this same drive to protect her students and fear of them becoming akumatized left her open.
- Psychologist Teacher: Two of her class-time routines includes leading her class in yoga and breathing exercises (which Mylène admits helps her with her anxiety) and encourages each student to say at least one nice thing to each other at the start of the day to build better relations.
- Reasonable Authority Figure: She is kind to the kids, and encourages them to run against Chloé for class president. She also encourages them to try to make friends with Chloé to make her a better person and takes Marinette outside to cool her off when she gets into a conflict with Chloé that nearly gets her akumatized.
- Redhead In Green: Downplayed. She wears a mint-green shirt that stands out against her white suit. It matches her green eyes and contrasts with her red hair.
- Well-Intentioned Extremist: Ms. Bustier is so cheerful and pure of heart that Hawk Moth is forced to take this track when akumatizing her: rather than convince her to indulge in her dark impulses or lash out at the world, Hawk Moth convinces her to use her powers to bring love to those around her. It manifests as Zombizou, who deliriously goes around changing people into lovestruck zombies, convinced she's making the world a better place.
Akumatized form: Kwamibuster
A science, mathematics, and physics teacher at Marinette and Adrien's school.
- Beauty Mark: Has one above her lip.
- Cool Teacher: At least cool enough to demonstrate what would happen with Rose's perfume if it hit an ignition source as opposed to just explaining it.
- For Science!: In "Kwamibuster", she is determined to prove the existence of kwamis to the world for this very reason.
- Icy Blue Eyes: She has deep blue eyes and is one of the most frosty teachers of the school.
- Jerkass Has a Point: She is right that Rose messing around with flammable perfume in a science lab is a massive danger to Rose and the rest of the class.
- Jerk with a Heart of Gold: Despite her grouchy, sharp-tongued, easily irritated and demanding nature, she doesn't hesitate to attempt to protect Max in "Robostus".
- Labcoat of Science and Medicine: She's the science teacher, so of course she wears one. Because of the show's Limited Wardrobe, she also wears it outside the school.
- Lean and Mean: Mendeleiev's angular features and lean physique suit her less than friendly demeanour.
- Meaningful Name: Dmitri Mendeleev was the founder and compiler of the modern periodic table of elements.
- Secret-Keeper: In "Kwamibuster", she learns about the existence of kwamis, but Cat Noir convinces her to keep quiet in order to keep them safe.
- Stern Teacher: In contrast to Miss Bustier, she seems to have a harsher and sterner personality.
- Terrible Artist: Her sketches of the kwamis on Alternative Truth are dreadful. Chloé — who has personally seen a kwami during her time as Queen Bee — is unsure of what they're even supposed to be.
- You Gotta Have Blue Hair: She has purple hair.
Mr. Armand D'Argencourt
Akumatized form: Darkblade
The P.E. coach and fencing instructor.
- Blue Blood: Claims to descend from a noble family that used to rule over Paris; thus, Paris is his birthright.
- Born in the Wrong Century: He espouses the idea of medieval knights and chivalry.
- Butt-Monkey: In "Riposte", where he spends a noticeable chunk of his screen time receiving Amusing Injuries.
- Master Swordsman: His fencing academy is the most prestigious one in all of Paris.
- Meaningful Name: Possibly. While his name does sound like a realistic French noble name, it can be translated as "Of money short"note , which could explain why he's a P.E. coach.
- Signature Move: The "dark blade", created and named by his ancestor. It involves deliberately leaving yourself open for an attack, only to quickly shift back into position and strike when your opponent decides to attack.
- Sore Loser: Downplayed. On the one hand, part of what turns him into Darkblade is the shame of losing the election by such a large margin; the other is Nadja Chammack's interview questions. However, on the other end, given his Jerkass opponent and the seeming Kick Them While They Are Down treatment from the public for said loss, it's kind of hard to blame this guy.
- Ye Olde Butcherede Englishe: How he speaks in the English dub.
Akumatized form: Dark Owl
The principal at Collège Françoise Dupont. In "Dark Owl", he tries his hand at vigilantism, becoming The Owl.
- Animal Motifs: He resembles an owl, befitting his principal status. He also has pictures of owls in his office. Fittingly, when he tries to become a superhero himself, he models himself after Knight Owl.
- Badass Normal: Subverted. The Owl has no powers...and is regarded as a loser due to his ill-thought-out decisions and general physical ineptitude.
- Big Ol' Eyebrows: He has large, bushy black eyebrows, reminiscent of the feather tufts on horned owls.
- Captain Ersatz: The comic book hero Damocles imitates as "The Owl" is this to Batman.
- Catchphrase: "Hoo-hoo!" as the Owl.
- Gadgeteer Genius: Subverted. His grappling hook is clearly a toy, with a ludicrously short range. He does manage to replace the string with a longer one, although he's not good at using it.
- Hero Does Public Service: After he's de-evilized, Damocles still runs around as The Owl, but he dials back his heroism to community service projects which are received much more favorably than his previous attempts.
- Hidden Depths: "Robostus" reveals that he is interested in computer science.
- I Just Want to Be Special: "Dark Owl" reveals that he's wanted to be a superhero ever since he was a young boy.
- Meaningful Name: His first priority is to be fair with his students, but he is unfortunately cowed by Chloé's threats, much like the Sword of Damocles.
- The Millstone: During his antics as "The Owl", he usually ends up in as much danger as the people he tries to "save", causing Ladybug and Cat Noir to come in and save him. Not only does it cut in on what little free time that they have in their civilian lives, but it is also obvious that should he involve himself with an akuma attack, it would lead to himself, Ladybug, Cat Noir and other civilians getting harmed in his efforts to help. After he is de-evilized, he dials it back a bit.
- Mission Control: Albert, a computer program who isn't as helpful as intended because of its poor voice recognition software.
- Non-Powered Costumed Hero: He tries to become one in the episode "The Dark Owl", but he doesn't really have the skills to pull it off. At the end, he decides to channel his heroic spirit into community service activities, like helping the homeless or rescuing stray animals.
- Reasonable Authority Figure: Mr. Damocles is serious, courteous, and authoritative, and generally tries to be this, but he struggles under pressure, especially when the Bourgeoises are the ones putting him under pressure.
- Super Zeroes: The Owl's incompetence and recklessness are quickly noted by the citizens of Paris.
- Wrong Genre Savvy: The Owl responds to Ladybug's insistence that he should wear a helmet by pointing out that she and Cat don't wear helmets. The fact that they get their powers from magical gems, while he is a wannabe Badass Normal, seems to slip his mind.
Mr. Fred Haprèle
Akumatized form: The Mime
Fred is an assistant educator at the school, a pantomime performer, and Mylène's father.
- Curtains Match the Windows: Fred has brown hair and eyes.
- Good Luck Charm: He keeps a picture of his daughter in his coat pocket for good luck.
- Good Parents: Fred loves his daughter very much and even keeps a picture of her in his breastpocket as a good luck charm.
- Hidden Depths: "Party Crasher" reveals that Fred is a fairly skilled trumpet player, as shown when he's jamming with Jagged Stone and Luka.
- Nice Guy: He is quite friendly and genial.
