Abandon Shipping: Certain patterns in Seasons 2 and 3 have caused viewers to drop the Love Square, namely the entitlement issues both Adrien and Marinette have regarding each other. Cat Noir has shown to disregard Ladybug's feelings and continues to pursue her despite repeatedly being told she's not interested and has feelings for someone else, in addition to not supporting Marinette in her conflicts with Chloé and Lila. On the other side of the Square, Marinette's stalker habits and obsession towards Adrien have been heightened from Season 1, to the point that some fans no longer see it as humorous, especially with regards to how she handles her love rivals Kagami and Lila. It seems the writers might agree, as the penultimate episode of Season 3 has Marinette finally give up on her obsession with Adrien, allowing him and Kagami to kiss, before breaking down in Luka's arms after everything that's happened. But come the first Miraculous World special, and the two still seem to interact with each other, even after that episode.
A small part of the fandom goes even further than that and thinks that ALL major players should be single and alone for the rest of the series, just to give us a break from all the romantic drama.
Accidental Innuendo: Ladybug's plan to defeat Reverser in his titular episode involves having Cat Noir hold on to the back of a kite (front facing away from it), blindfolded, holding her yoyo between his teeth. The way it looks, one would be forgiven for thinking that she coerced him into doing something... kinky.
Alternate Self Shipping: The show already has split identity romance problems with Marinette/Ladybug and Adrien/Cat Noir, but some fans will split up the identities entirely to make them attracted to themselves.
Arc Fatigue: The Love Square, as many fans became tired by how long Marinette's relationship with Adrien took to develop. For now with the end of Season 3, it seems all this has come to a halt for now, as they both decided to start a relationship with different love interests.
For those who want Chloé to undergo a HeelFace Turn, episodes like "Antibug", "Despair Bear", "Zombizou", and the Queen's Fight trilogy all set her on the road to a potential one by showing off her nicer side and having her go through Character Development.
Likely in response to Squick regarding the images in Marinette's imagination spot when she considers that Hawk Moth may be Adrien in the sneak peek from Korean Comic-Con 2017 (not helped that there was no voice audio, so one could easily mistake the scene as Marinette having a crush on Hawk Moth), the images were changed in the final version to Stylistic Suck edits of Adrien's and Hawk Moth's vector images and effects were added to make it more obvious that Marinette is just slippery-sloping her What If?.
Over the course of the series, Hawk Moth had many What an Idiot! moments when it came to ordering his minions on how to obtain the Miraculouses. But the "Heroes' Day" special averts that; he planned for nearly every possible move the heroes could make and those plans didn't backfire, at least not due to his poor thinking, but to the heroes' quick thinking.
To say that many fans were livid about Adrien's leniency towards Lila's manipulations would be an understatement, especially in "Chameleon" where he stops Marinette from (rightfully) preventing Lila from further controlling her classmates. He finally reaches his limit in "Onichan" when her machinations cause emotional harm to his family and friends and almost puts Ladybug in serious jeopardy. He promptly tells Lila where to shove it in both his forms and threatens to break his ties from her in his civilian identity if she doesn't stop hurting the ones he cares about. The fans were further pleased in "Ladybug", where he actively did his best to defend Marinette against Lila's accusations. Those mad at Alya and Nino for apparently believing Lila, a relative stranger, over one of their close friends were also pleased with the episode, in which neither of them buy into Lila's claims either.
Season 3 ends with both of the heroes deciding to try and move on from pursuing their romantic partners for the moment, likely as a response toward how divisive said crushes had gotten.
A number of viewers were getting tired of how the show is constantly dragging out the Love Square. "Cat Blanc" gives us a good reason to wait: we're presented with a Bad Future that started when Marinette and Adrien revealed their identities to each other and hooked up, explaining that it would be a very risky move to make as long as Hawk Moth (or at the very least, Gabriel Agreste as Hawk Moth) is still at large.
A recurring complaint about the show has been about how bland Ladybug's costume looks, especially when compared to the more visually-interesting costumes the later heroes have been getting. Season 4 rectified these complaints by giving her a new costume whenever she summons her Lucky Charm.
Awesome Art: SAMG's animation (for the whole of season 1, and half of seasons, 2, 3, and 4 - as well as the first two specials in the Miraculous World series). They have been known to handle its episodes and finales with the most fights between the characters. It is far above the other studios (DQ, Assemblage, and Symbosis) and many episodes are full of eye candy. It goes a lot further than the storyboards, adding lot of details in the whole animation. Its facial expressions are also one of the best you can get from a All-CGI Cartoon, adding emotion to the characters. The unique rendering can also be immediately recognized and it also loves using night and evening lighting. It's worth noting that this studio released a wonderful artbook of the show, but unfortunately, it was only released in South Korea. The studio stopped being a co-producer after season 1 for reasons unknown.
Badass Decay: Hawk Moth in season 2 had more difficulty keeping his own villains in line (Robostus and Gigantitan being prime examples), when in season 1 he managed to control his minions without any problem. His Benson-like tantrums in "Gigantitan" didn't quite help his seriousness.
Better on DVD: Because the show is notorious for being broadcast Out of Order, watching the episodes in succession does answer a lot of questions left up in the air and a lot of the events in later seasons become more clear.
Whether Ladybug and Cat Noir are truly equal partners. Does Ladybug constantly winning battles singlehandedly and essentially becoming Master Fu's sole confidant make her too overpowered compared to Cat and thus make him unnecessary, is their partnership perfectly fair the way it is now (since Ladybug is the only one who can purify akumas and fix the damages and thus Cat must protect her at all costs), or does Cat not deserve to learn more due to his various displays of immature and selfish behavior?
The events of "Chameleon" and whether or not Marinette, Alya, and Adrien were justified in their reactions are still subject to heavy and volatile debate.
Debates over which characters deserve a Miraculous at this point have been running through the fandom since the series began. It doesn't help that, at the rate the show's been going at, every major character around Marinette and Adrien's age is gonna get a Miraculous, if only temporarily.
Should Marinette/Adrien still be the endgame pairing at this point? On the one hand, you have the fans who love their dynamic both in and out of costume and argue that they have good reasons for not revealing their identities to each other yet and that the slow-burn nature of the romance is what makes it so appealing; on the other, you have the detractors who argue that the romantic tension and near-reveals have long overstayed their welcome and that the various actions Marinette and Adrien have taken as a result (either on solely the former's end, solely the latter's end, or on both ends) have made the pairing too toxic to be viable.
Season 3 as a whole has been contentious amongst the fanbase, largely thanks to debates over the prominence of Base-Breaking Character Lila, the direction taken with Chloé's character arc, and various actions taken by both Marinette and Adrien as a result of the Love Square.
The finale especially gets hit hard with this. Was it a solid conclusion to the season that provided and interesting twist to the show's formula going forward, or is it a hackneyed mess of ass pulls and OOC moments? No one fan can agree on this, let alone which parts of it were well-written (with the handling of the Love Square, Chloé's actions, and Master Fu getting Put on a Bus being especially contentious).
Captain Obvious Reveal: Pretty much every fan suspected that Gabriel Agreste was Hawk Moth before the season 2 premiere made it official.
Not many people were surprised when Jagged Stone was revealed to be Luka's father in the season 4 premiere.
Cliché Storm: Aside from the Paris setting, it's a fairly run-of-the-mill teenage superhero series with Magical Girl elements, what with a thematic Monster of the Week every episode, B-plots involving typical school issues, and archetypical characters.
Crack Pairing: The two have shown nothing but contempt for each other so far in canon, but a number of fans ship Chloé and Kagami together. Curiously, this seems to go hand-in-hand with anti-Lila fics, where they're often made two of Marinette's allies against Lila.
Crosses the Line Twice: Chloé's actions in "Dark Cupid". Tricking Adrien into signing a poster that she already wrote a fake love confession on and then boasting about it to his fangirls? Not funny. Chloé claiming that one of these girls isn't crying hard enough and having Sabrina shove the poster in her face to make her cry more? Now it's funny.
Chloé badgering Rogercop to punish Marinette for supposedly stealing her bracelet is rather petty. Chloé following him outside and getting into his car to keep bitching about this is just sad. Her still continuing to whine over this alleged infraction while he's blitzing around Paris in a flying car, under attack by Ladybug and Cat Noir, is just hysterical.
Kagami and Luka, being obstacles to the ever-popular Love Square, got hit with this as soon as they were revealed. Arguably, it's worse for Kagami than it is for Luka; while Luka became an Ensemble Dark Horse in his own right whose popularity has only grown, Kagami received a ton of hate from the Ladynoir shippers after episodes like "Animaestro" and "Oni-Chan". The fact that season 3 ended with Marinette and Adrien all but hooking up with Luka and Kagami, respectively, only served to make things worse for both of them.
Adrien/Cat Noir is often hit with this in fics that pair Marinette with someone else, usually being turned into a spineless victim-blamer who harasses Marinette for not going along with Lila and having his Entitled to Have You nature towards Ladybug cranked Up to Eleven.
Don't Shoot the Message: In "Weredad", Cat Noir comes back to the bakery to apologise after Tom gets Akumatized over his rejection of Marinette, but Sabine reassures him that he doesn't have to be ashamed of how he feels, regardless of how Tom chose to react to it. While the advice and who it's given to are fine, the scene has attracted criticism for creating a massive Double Standard considering the treatment of Marinette/Ladybug in previous seasons, especially in the episodes where she rejected Cat Noir and wasn't given any such support.
Rogercop. Up until he seized control of Paris from the mayor, the worst of his crimes was excessive force; he only attacked people that had been proven to have committed wrongdoing, such as the litterer, the mayor for abusing his powers, and Ladybug and Cat Noir for preventing an officer from making an arrest, i.e. knowingly aiding a criminal. But he is still under Hawk Moth's control, who then orders him to take Ladybugs and Cat Noir's Miraculouses. It can be easy to forget that he approached everything he did with equal amounts of seriousness and punishment, especially since he had a sympathetic motivation.
Chloé has a surprising amount of fans for someone who has few Pet the Dog moments in the entirety of the show so far and has singlehandedly Akumatized at least nine people with her cruel antics. Being revealed as one of the Miraculous holders for Season 2 only increased her fans' adoration for her, as many see this as a sign of a redemption arc in the future. To say that these fans were not happy with the season 3 finale subverting that arc would be an understatement.
Gabriel Agreste, even prior to the reveal that he was Hawk Moth, had a lot of fans and people defending his parenting of Adrien. (and post-reveal, his general actions as a supervillain). This often takes the form of people latching onto his Adult Fear reactions regarding Adrien's safety in episodes like "Riposte" and "Gorizilla" as proof of Even Evil Has Loved Ones, while ignoring or at least downplaying the fact that Gabriel put him in danger to begin with.
Lila had a lot of Fanon character development even before she debuted on the show, and after "Volpina", there were many sympathetic interpretations of her. Naturally, several fans were unwilling to give up on these interpretations once the season 2 finale and "Chameleon" proved she was meant to be a Hate Sink, leading to several fan works where she gets hit with this treatment. Usually, this gets achieved by citing a potential Freudian Excuse for her (her being publicly humiliated by Ladybug for telling lies, Hawk Moth manipulating her, her parents being constantly absent, her feelings for Adrien apparently being genuine, etc), ignoring everything she does post-"Volpina", or by writing her into a scenario where she's the lesser of two evils compared to whatever character is getting subjected to the Ron the Death Eater treatment.
Felix is in a similar situation to Lila — he had years of fanon character development as a Jerk with a Heart of Gold, so naturally many fans prefer to use that characterization over his canon Manipulative Bastard tendencies. Part of the reason for this is that, while the original concept for Felix was initially cut from the show because the creator wanted to avoid portraying a bad romantic role model, many fans have complained that his replacement (Adrien) demonstrated equally problematic qualities but had these glossed over by the writers, making Felix's characterization come off as an attempt to make Adrien look better by comparison.
Due to the fact that this is 3D CGI show, fans will theorise from continuity errors and reused item models, even if it's unintentional and just for budgeting purposes. For instance, theories sprung up over Madame Agreste's brooch being the same as the one Chloé gives Sabrina in Antibug, but Thomas Astruc Jossed those on Twitter, explaining they were simply both from the Gabriel brand and were unrelated.
There's a fan theory that posits that the Miraculous go to/work best when they are wielded by individuals who lack the traits the respective Miraculous embodies or represents, with the ideal of making the wielder better, more wholesome people. Examples include: the luckless and seemingly "responsibility incompetent" Marinette gaining the lucky charm Ladybug Miraculous, finding her lucky strides and being able to showcase competency and responsibility; the strait-laced, well-to-do, but trapped introvert Adrien gaining the "unlucky" and "destructive" but nonetheless free Cat Miraculous and becoming more extroverted and outgoing, with an emphasis on whimsical freedom. Likewise, the Butterfly Miraculous representing progression, change and transformation fit well with Hawk Moth's powers, as well as its wielder Gabriel's steadfast adherence to the past and inability to move on with his life, which is then contrasted with the reality that Gabriel clearly rejects what his Miraculous symbolizes, corrupting and twisting the nature of its powers to create super-villains who are weighed down by their on-going negativity that they can't move past from.
Going from this, this theory is also used to predict new potential Miraculous wielders, by seeing what the Miraculous' animals represents and who best fits the need for those traits in their lives. Nino's now confirmed Turtle Miraculous represents Nino's almost juvenile youthfulness being tempered by a sagacious wisdom and understanding, the likes of which the character has been shown to shun at times, whereas Alya, often self-destructive in the pursuit of truth, would do well to embrace at least a healthy dose of illusion and falseness via the Fox Miraculous. Chloé, in turn, could use, among other things, a nice helping of honey-like sweetness and selfless diligence and dedication in her life, as represented by the Bee Miraculous.
Hawk Moth in Season 2 had a much harder time keeping his akumas in check. Does it hint to Nooroo rebelling against him? Is it the consequences of using a Kwami for evil actions? Or is he simply suffering Villain Decay? On the other hand, one might begin wondering just how much control Hawk Moth ever had over his akumas in the first place. After all, the ability of the Butterfly Miraculous is to empower others, not necessarily control them.
A rising theory that has popped up since the release of "Feast" and "Ladybug" is that Adrien is actually a sentimonster created by Emilie when she wielded the Peacock Miraculous.
Evil Is Cool: The akumatized villains are quite popular for their unique designs and powers, and the fact that most of these are transformed from recurring characters. Even those who are only in their debut episode are still fun to watch.
Evil Is Sexy: Between the number of relatively attractive people that get Akumatized and the fact that a number of Akuma outfits involve skin-tight bodysuits, plenty of akumatized villains have gotten this reaction from fans.
Several kwamis who have been introduced in the show don't have an owner yet, leaving much room for fans to imagine other heroes.
The kwamis and the Miraculouses have existed for millennia long before humans even did (Plagg apparently killed the dinosaurs) and have been used by various people to be heroes over the course of History, with few details given about the previous owners. Have fun imagining previous generations or Miraculous users.
The future alluded to in "Timetagger" has lots of potential for fanfics.
Since Mayura created a copy of Ladybug, some people suspect every character to secretly be a sentimonster. The most popular targets of this theory are Adrien and Nathalie.
Princess Justice in general is a prime target for fanfics for a couple of reasons. She is a canonical Akumatized form of Marinette, which on its own has plenty of potential in the same vein as Cat Blanc. Additionally, while she has technically appeared on the show, she never actually transformed, leaving her appearance and powers wide open for fan interpretation.
Thanks to its status as a major base-breaker, fans also have a tendency to rewrite or just ignore the majority of season 3.
Fan-Preferred Couple: A strange example of Felix (from the original PV) and Bridgette (the Fan Nickname for the Marinette also from the original PV). They are characters that technically don't even exist anymore, but many of the fandom enjoy them and their dynamic regardless (it also helps that the canon Felix is quite a Base-Breaking Character). As a result, many Miraculous fanfics feature them as actual characters and often as a couple.
Fashion-Victim Villain: A lot of the akumatized villains often fall under this, wearing extremely bright and clashing colors, not helped by many of them also having bizarre skin tones and ridiculous hairdoes. Bubbler, Simon Says, Reflekta, Style Queen and especially Party Crasher stand out the most.
First Installment Wins: For Zagtoon as a whole; the only other shows they currently have out are ignored for the most part and considered So Okay, It's Average by the people who have seen them, and most of the shows they have in production have been ignored or accused of ripping off other shows, including this one.
Franchise Original Sin: One of the major complaints fans had about season 3 was the characterization of both Adrien/Cat Noir and Alya; the former was lambasted for his Extreme Doormat behavior in the face of Lila and his entitled behavior towards Ladybug (and Karma Houdini status in regards to this behavior), the latter for her exceptionally poor journalism skills (to the point of blindly trusting a comparative stranger over her supposed best friend). However, all of these traits have been present in the show since season 1; Adrien's always been a doormat in the face of his childhood friend Chloé (and that at least had the excuse that she was his Only Friend for years) and has been poorly handling his crush on Ladybug with no consequences since at least "Copycat", and Alya's poor journalism skills were what got her akumatized in "Lady Wifi". They were forgiven back then because the show was still new, so these traits hadn't been overused, and there were signs of Character Development that the fans thought would stick.
Fans of Code Lyoko and Miraculous Ladybug tend to get along (with several people belonging to both fandoms). This is due to the similarities between both shows (Animesque French shows dealing with Parisian unsung heroes) and the fact that Miraculous's creator Thomas Astruc also worked on a few Code Lyoko episodes.
With the Shugo Chara! fandom. Mostly because both series have cat boys as one of the main love interests, which is notable since cat girls are much more common in both western and Japanese media. There is plenty of fan art with Ikuto and Adrien interacting in their cat forms. There are other similarities too, like Marinette and Amu being more confident as their alto egos and being fashionistas. They even have identical crushes: one romantic interest is the cool, older guy who plays a stringed instrument with blue hair and the other romantic interest is the school idol in the heroine's class who has blonde hair and is known for their kindness.
My Hero Academia is also popular amongst the Miraculous fandom due to their similar plots: a young dark-haired Asian hero is scouted by a experienced hero and has been given superpowers. Although the role of Adrien/Cat Noir is divided into three other main characters: Bakugō as the blonde foil (and rival), Todoroki as the one with the mysterious and intriguing home life, complete with the abusive father, and Uraraka as the canonical love interest.
When it comes to crossover fanfiction, Miraculous Ladybug fans are quite cozy with Persona fans. This probably has something to do with the fact both series really like butterflies. Now somewhat Hilarious in Hindsight, with one of the new season 4 episode being called 'Truth', and Cristina Vee (Ladybug's English VA) being the co-host of AnimeTV with Johnny Yong Bosch (Yu Narukami's English VA).
Hawk Moth's name refers to a particular family of moths, the best known of which are the death's-head hawk moth, made famous by the poster for Silence of the Lambs.
Antibug. There really are ladybugs that come in black with red spots, variants of ladybugs known as harlequins. However, they are an invasive species and considered pests in North America and Europe due to their damage to crops, infesting houses, and aggressiveness.
In Weredad, the akuma that turns Tom Dupain into the titular villain is a flower. Him becoming a werewolf-like creature is most likely a reference to the curse of lycanthropy being caused by a certain flower and a possible cure for such a bane being the destruction of said flower.
The Reflekdoll from the episode of the same name appears to be a reference to the Royal de Luxe "Little Giantess" giant marionette.
In Startrain, at one point we see another galaxy out the front window of the train: the Large Magellanic Cloud, from roughly 11,000 light years away. Startrain and Pegasus are both capable of ultra-fast intergalactic travel.
While previous French animated series such as Wakfu had niche English-speaking fandoms, Miraculous has a huge following in the English-speaking world, which goes even further into this trope as many of its fans are also fans of Japanese media (anime and manga).
Adrien/Chat Noir tends to get more attention than Marinette/Ladybug from North American fans, though it's downplayed by his status as a Base-Breaking Character.
Girl-Show Ghetto: Despite the fact that the show is presumably meant to have a unisex demographic, the majority of the merchandise has been aimed at young girls. Additionally, the female characters have far more prominence than the male characters — Adrien/Chat Noir only has a few toys to his name, and Nino/Carapace is practically nonexistent.
Growing the Beard: The cluster of episodes towards the end of season 1 (beginning with "Simon Says", the first episode providing a glimpse into the Myth Arc), is the point where the series starts to sprinkle intrigue and a sense of continuity into its Monster of the Week hijinks. Also see Better on DVD, as the series being broadcast Out of Order naturally muddies this.
Harsher in Hindsight: In "Startrain", Marinette is afraid to leave Paris because she fears that Hawk Moth will attack in her absence and she'll be unable to do anything about it. The New York special brings her fears to life, much to her horror.
He Really Can Act: Bryce Papenbrook (Adrien/Cat Noir) really shows off his range in "Cat Blanc", when he manages to vocally cover every aspect of the titular akuma's twisted personality.
In "Simon Says", Gabriel refuses to participate in the game show and initially refuses to heed Cat Noir's orders, saying that no one can control him or tell him what to do. He's... kind of right, since as Hawk Moth, he can akumatize himself.
A Crack Fic, Miraculous Headache, does a retelling of Season One episodes with the characters' personalities flanderized. The "Timebreaker" chapter has Alix become a frequent time traveler for future chapters, some of which have her travel back in time to secretly help Ladybug and Cat Noir, particularly for its final chapter. Come "Timetagger", Alix indeed becomes a time-traveling warrior that aids the main heroes, wielding the Rabbit Miraculous to do so.
A rabbit-themed super heroine from the future who (occasionally) travels to the past to help the younger selves of the people she knows defeat threats? Are we talking about Future Alix/Bunnyx or Chibiusa Tsukino/Sailor Chibi Moon from Sailor Moon?
"Lady Wifi" stands out as this, relying on Alya being a poor investigator and a Horrible Judge of Character (when she suspects Chloé of being Ladybug) and Hawk Moth being a terrible strategist (when, after Lady Wifi has Ladybug restrained, he tells her to release her, force her to use her Lucky Charm to save Cat Noir, and then let her transformation run out, rather than just pull out the earrings immediately). The former point becomes even stupider after the Origins two-parter revealed that Ladybug saved Chloé from falling on her second day in the suit, which Alya, Nino and Adrien seem to have forgotten about.
"Chameleon." Lila's web of lies would have fallen apart if Ms Bustier had ever asked her to bring in a doctor's note, if Marinette had contacted Jagged or Penny about whether any part of the cat-rescuing story was true, if Alya had tried to verify Lila's stories the same way she expects Marinette to, if Max (or anyone else) remembered he was wearing glasses when Lila was supposedly trying to shield his face from a scrunched-up napkin, or even if Lila had just not bothered trying to get closer to someone who already knows her to be a liar.
In "Syren", the titular akuma ends up flooding the entire city. How many people drowned? Were the deaths undone with Lucky Charm like the rest of the damage usually caused by akuma, or did everyone who died stay dead?
It appears that after the episode, "Timetagger", people who died to akuma related attacks can indeed be brought back to life, as one person who got sent back in time ended up becoming the Mona Lisa.
The ending of "Timebreaker" has Alix stating that she should never have asked someone else to hold onto the watch for her, and learning a lesson about her responsibilities. But it's hard to see why this is presented as irresponsible considering that her only other option at that point was to carry the watch while racing Kim, meaning an obvious risk of dropping it and breaking it. At best, you could argue she should have left it with her father at the restaurant to take home, but that just raises the question of why he didn't suggest as much when he knew she was about to leave to go skating. Really, Alix's only mistake was not choosing someone smart enough to remember they have pockets (or a purse, in Marinette's case).
"Rogercop" presents Marinette trying to look for other suspects as being no better than Chloé and her father's kneejerk accusations, which isn't entirely fair. It becomes especially jarring when she still gets called out for making non-specific, conditional statements like, "If there's a culprit, they're in this room."
In "Malediktator", Marinette and the rest of the class are portrayed as in the wrong for wanting to celebrate that Chloé is leaving Paris. Adrien objects to this because she's his friend, but he's been witnessing her bullying up close for a long time now and the story doesn't allow Marinette to point out that she has been getting away with it for years.
Sabrina. Yes, she's allied with Chloé and occasionally is as much of a jerk as she is, but she also has no idea what real friendship is, and gets easily crushed. Her father gets fired in one episode and turned into an akuma, forgetting who she is, and she can't understand that Marinette needing to handle a personal thing the day before a project is due is not the same as Chloé refusing to do schoolwork. Heck, when she gets akumatized the first time she doesn't even get a cool Evil Costume Switch! She's just invisible, and her outline shows that her outfit hasn't changed.
Chloé of all people became one in "Despair Bear": in the past it's revealed that her mother walked out on her when she was just a child (complete with a picture of her crying her eyes out when it happens), stunting her emotional growth and leaving her clingy to Adrien because he was there to comfort her. In the present, Adrien threatens to break up his friendship with her, and the prospect of this turns her into a miserable, anxious wreck, showing just how damaged her psyche is.
Nathaniel may not be a major character, but it doesn't prevent him from being shipped with a lot of other characters in the show. This includes, but isn't limited to, Marinette/Ladybug, Adrien/Cat Noir, Chloé, Sabrina, Lila, and Juleka. As of "Reverser", the list includes Alix and Marc.
Misaimed Fandom: A lot of fans want Marinette/Ladybug to call out Lila publicly for her lying, and cheered her on when she did so in "Volpina"; however, the end of that episode (and the aesop in later episode "Chameleon") make it clear that Marinette would be in the wrong to do so for various reasons. (Whether or not said stance is the correct one to take is hotly debated by fans.)
Mis-blamed: Some fans complain that the dubbers of the English version ruined the dialogue by putting in ridiculous words and phrases, especially "de-evilize." However, it was the show's writers at ZAG, not English dubbers, who wrote the English version, which the animation of the show was built around. Thomas Astruc even admitted that "evilize" was his idea.
Marinette/Ladybug, of course. She's a Cute Clumsy Girl that's awkward around her crush, gets easily flustered and stammers when she receives any attention in school, and frequently blushes and assumes the worst when things are going bad for her.
Sabrina as well. She's something of a jerk, but she really is pretty sweet and supportive when she's not directly aiding in one of Chloé's schemes. With all the suffering she endures from Chloé, you really want to give the poor thing a hug.
Most of the fandom agree that Adrien as Cat Noir is one of the cutest things ever, due to his funny personality, his silly puns, and especially his cat-like antics such as purring, running on all fours (occasionally), or allowing Ladybug to pet him the way one would pet a cat.
Chloé crossed it in the two-part season 3 finale by joining Hawk Moth and getting akumatized willingly just because Ladybug didn't come to give her the Bee Miraculous when she wanted it (even though Ladybug had previously told her she couldn't because Hawk Moth knew her identity and could use it against her), and ultimately feeling no remorse for it afterwards. It doesn't help that her actions led to all the Miraculous users so far except for Ladybug and Cat Noir (and Bunnyx because Alix in the present hasn't used it yet) having their identities revealed to Hawk Moth, potentially robbing them of the chance to use them again. Thomas Astruc himself has rather bluntly confirmed on his Twitter account that Chloé's actions here have made her irredeemable◊.
Hawk Moth crossed it in "Cat Blanc": in the alternate timeline, he blackmailed Marinette into breaking up with Adrien so he could akumatize her, learned his son was Cat Noir when he transformed to save her, revealed Emilie's condition to him and attacked him when he refused to team up with him, and took advantage of his emotional turmoil to create one of his most dangerous akumas to date. All of this proved that, if push came to shove, he'd be willing to harm his own son if it meant achieving his goals.
For those who discount the above due to it taking place in an alternate timeline, he gleefully crosses it in the New York special: first, he had Nathalie use a Sentimonster to wreck Paris in an attempt to distract Ladybug, causing irreparable damage because Marinette didn't stop it before it disappeared. Then, he has Techlonizer use the Eagle Miraculous to relieve the New York superheroes of their fears and inhibitions, allowing them to cause all sorts of destruction, which included Majestia attempting to move the moon towards earth. Finally, he has Victory prepare to launch nukes if Ladybug and Cat Noir didn't show up.
Lila crossed it in "Chameleon" by being the first person to willingly become akumatized, making it perfectly clear how much of a Hate Sink she is.
Bob and XY crossed it in "Silencer", where they not only plagiarised Marinette and Luka's band, but also threatened to shift the blame onto Marinette when she demanded justice, leading to the normally calm Luka being akumatized into Silencer. Bob even went as far as to use illegal techniques and defamation threats in order to promote his son's career for money, which would've gotten him in serious legal trouble in a more realistic setting. If that didn't push Bob over the line, using Ladybug as a Human Shield to save his own skin when Silencer attacked almost certainly does the trick. Is it any wonder why Jagged doesn't get along with them?
In "Lady Wifi", Marinette recognizes that Alya is the Villain of the Week by the charm on her cell phone. It may not seem narm-y, until you see that aside from her outfit and mask, she looks exactly the same as she always does. It becomes even more so in "Rogercop" when Sabrina is able to immediately recognize that Rogercop is her dad even though his face and outfit is obscured.
Some of the villains can qualify, regardless of if they turn out to be Not-So-Harmless Villains. For example, the Bubbler and Mr. Pigeon; while they both may be legitimate threats in practice — those bubbles could have potentially suffocated every adult in Paris leaving vulnerable children alone, and pigeons and their waste are a genuine health concern, being considered "flying rats" — it's still hard to take their motifs seriously, which really isn't helped by both men's rather embarrassing-sounding monikers, the Bubbler's attempts to be Totally Radical, and Mr. Pigeon acting like a pigeon, complete with cooing and flapping his arms like wings.
"Princess Fragrance" was the audience's first taste of a Musical Episode, albeit not one that could qualify entirely as one (the dialogue was sung but there were no numbers). The musical elements were overlooked. Then the Christmas Episode rolled around, this time a bona fide Musical Episode to boot, with numbers impossible to look away from without missing plot-important sequences. It wasn't... pleasant.
The term "de-evilize" can be awkward to listen for some English-speaking people.
The Christmas special may be the first example of singing one's attacks, as Cat Noir sings "Cataclysm!" as he rushes to destroy a giant Christmas tree. The angst of his preceding anti-Christmas musical number doesn't help matters.
Chris, despite looking no older than 7, is voiced by an adult male voice actor in the English version, and he plays him with such an annoyingly screechy voice.
Gabriel is supposed to be a renowned fashion designer, but it's hard to take that seriously when the cloak he designed to symbolize Audrey and Andre Bourgeous' "eternal love" in "Heart Hunter" looks like a glorified get-along shirt. Of course, he did specifically make it to piss them off.
The use of cheesy one-liners, predictable story beats, and a few truly laughable villains make the show hard to take seriously at times, but it fits well with the classic Magical Girl and superhero shows it's a throwback to. Also, all of Cat Noir's terrible puns.
Cat Noir, when under the control of "Princess Fragrance", sings everything he says with the most ridiculously-sounding deep voice.
The costume designs, while ridiculous to an extent, are still fitting for the respective characters.
Never Live It Down: The saltier side of the fandom holds a powerful grudge against just about anyone who did anything to wrong Marinette in the episode "Chameleon", especially Alya and Lila. That said, it's hard to overstate just how much that single episode has changed the fandom itself.
While Adrien may have used the phrase "She is just a friend" when referring to Marinette only once or twice in canon, the fandom still ran with it like no tomorrow, and now he is forever remembered as the most oblivious teenage boy ever.
Chloé's butler in "Antibug" when he's pretending to be an akuma villain while playing with Chloé with a moustache. Eventually became an Ascended Extra in Season 2, even getting his own Akumatized form and episode.
The photographer in "Reflekta" (Vincent) who won't take Chloé's nonsense.
Periphery Demographic: The show has a good amount of teen-to-adult viewers, perhaps due to the franchise having been planned for those viewers before it was toned down for a younger audience. Most adult fans seem to like it well enough regardless. It even won the Teen Choice Award for Choice Animated Series in 2018.
The Love Square, where we have four different ship names just for the two main characters; LadyNoir is a popular term for the pairing in the fandom for Ladybug/Cat Noir, Ladrien for Ladybug/Adrien, MariChat for Marinette/Cat Noir, and Adrienette for Adrien/Marinette. As they act quite differently in their hero roles than they do in civilian life, each of those really is quite distinct.
Adrien/Nino = Adrino, while Cat Noir/Nino = Ninoir.
Adrien/Alya = Alyadrien
Adrien/Nathaniel = Adrinath, while Cat Noir/Nathaniel = CatNath.
Adrien/Luka = Lukadrien.
Adrien/Kagami = Kagadrien or Adrigami
Marinette/Luka = Lukanette
Marinette/Kagami = Kagaminette
Marinette/Alya = Alyanette, while Ladybug/Alya = Alyabug. Fans who avert the One Mario Limit and use Lila's Akumatized name for Fox Alya refer to Marinette/Fox Alya as Volpinette, and Ladybug/Fox Alya as Volpibug, which causes some overlap with the L Square below. Since the TFOU leaks in August revealed Alya's heroine name to be Rena Rouge, it's likely the ship names will change to reflect that.
Marinette/Chloé = Chlonette, while Ladybug/Chloé = Chlobug. Chloé's Bee heroine Fan Nickname is Queen Bee, Marinette/Queen Bee = Maribee, and Ladybug/Queen Bee = Ladybee. Her official name was leaked in August as Queen B, which may not affect the present ship names.
Marinette and Lila constitute the L Square, created before the SDCC 2016 spoilers confirmed Lila wouldn't be the Fox Miraculous holder. Marinette/Lila = Lilanette, Marinette/Volpina = Volpinette, Ladybug/Volpina = Volpibug, and Ladybug/Lila = Lilabug.
There is also the massivelycontroversialSin Square comprising of Gabriel Agreste and Marinette. Gabriel/Marinette = Gabrinette, Gabriel/Ladybug = Gabribug, Hawk Moth/Ladybug = Ladyhawk, and Hawk Moth/Marinette = Marimoth.
Realism-Induced Horror: "Troublemaker" shows that even in a fantasy setting where various transformation trinkets give people superpowers, the threat of someone invading your privacy and broadcasting your private affairs to the world remains very real —and that despite her powers, there's nothing Marinette can do to stop it.
In the original pilot short, Cat Noir was a boy named Félix; he was scrapped and replaced with Adrien when the show began actual production as the creator decided Félix was too cliché and unpleasant. Fans still loved him either way, and in fanfic, Félix often appears as Adrien's older/twin brother, who may have been his predecessor as Cat Noir or is even sharing the role with him. Félix's continual popularity eventually got him an appearance in the show, in which he's been made Adrien's cousin.
To go with Félix, fans created Bridgitte, who is supposedly Marinette's counterpart from the pilot short. In reality "Bridgitte" is just Marinette with a slightly different design, but as with Félix, fanfic often makes her and Marinette siblings.
Fans have also brought in versions of the heroes that were originally meant to fight alongside Ladybug and Cat Noir. The most common are counterparts to Melodie, Mercury, and Kid Mime (almost always named Allegra, Allan/Alan, and Claude).
Romantic Plot Tumor: The love square between Marinette/Ladybug x Adrien/Cat Noir. While it was a creative aspect when the show first began, after three seasons of the same predictable plots of Will They or Won't They? and close calls in finding out they had been loving their alter egos, many fans have gotten sick of it and just wish the two of them could find out each other's secret identities and wrap this aspect up, or at bare minimum make it go away. It doesn't help that Marinette's paranoia about even them knowing each other's secret identities has led to a lot of trouble when they couldn't contact each other or know where the other was, far more than the potential trouble that could be caused by them knowing, and it's really transparent that keeping the love square alive is the only out-of-universe reason.
Considering that Evillustrator indulged in Poke the Poodle moments before it seemed that Marinette betrayed him, and he only wanted to take her out for a romantic cruise on the Seine and on his birthday, it is really hard to sympathize with Marinette and Cat Noir's well-intentioned attempt to disarm him.
Few, if any, viewers found themselves eager for Ladybug and Cat to hurry and stop Rogercop before he could get to the Mayor, even more so when Rogercop simply forced the jerk to resign on live television instead of outright murdering him or anything.
Robostus may have started out just like any other akuma in the show, and then he turns on Hawk Moth and starts firing his own security system of missile launchers against him. Many viewers, especially those who despise Hawk Moth, will find themselves finding it hard to wish that Ladybug and Cat Noir take him down quickly.
Considering that Bob Roth threatened Marinette in front of him, it's hard not to root for Silencer wanting to get a confession out of him. He doesn't even seem that interested in getting the Miraculous. It also helps that he promised not to hurt Marinette and then confessed his feelings for her. Cat Noir even briefly feels this way In-Universe, but Ladybug shoots him down because she doesn't believe in forced confessions. Engineered public confessions, however...
One of the most popular Fanfic Fuel plots is for an episode where Hawk Moth succeeds in akumatizing Marinette and/or Ladybug. It very nearly happens in "Chameleon" and "Ladybug", but was ultimately subverted.
Scapegoat Creator: Thomas Astruc has become the main target of fans' complaints about the show. His rather controversial behavior on Twitter hasn't helped matters.
Mayor André Bourgeois, Chloé's father and the mayor of Paris. He spoils his daughter rotten, doesn't acknowledge that she causes a lot of trouble, and is as helpless as any authority figure to handle akuma. On top of that, he very blatantly abuses his position to order people around, making it very clear where Chloé gets it from. He seems, however, to get better by "Malediktator", which rescues him for some.
Self-Fanservice: Fan Art of Cat Noir frequently depicts him as much more muscular than in the show itself, and though Ladybug's skin-tight suit is, well, skin-tight, some artists make her bustier and curvier than she actually is. The same applies for the other heroines and a number of akumatized victims.
In a non-romantic example, Alix and Nathaniel are this to all of the platonic relationships in the cast. They are the only two in their class without official best friends, so fans like to make them close so that nobody in the class is alone. This was eventually canonized in "Reverser".
It's also popular to pair Nath with Chloé or Lila, taking care of both his crush on Marinette and the girls' on Adrien.
Often Myvan, Julerose, and Kimax shippers come hand-in-hand, as ships that involve minor classmates unrelated to the Love Square.
Chloé/Nathaniel has become a very popular pairing among fans, despite their only interaction being in "Evillustrator", where the latter tried to kill the former as the titular villain. Fanfics, fanart, hell, even fanmade comics based around them have become quite common.
And that's not even going into the popularity of Lila/Nathanäel, even before they wound up sitting next to each other in class.
Chloé/Luka is a surprisingly popular pairing despite the two never interacting. They've got a bit of an Opposites Attract appeal.
Luka and Lila have never met in the show (and would likely dislike each other), but are still shipped.
When the trailer for "Félix" came out, people immediately started to ship the titular character with Lila. The episode's plot only reinforced this.
Luka did not join the trip to New York, that doesn't stop people from shipping him with Jess since both are great at playing the guitar.
The season two premiere. You hear that sound? That's the sound of most of the fandom screaming "I KNEW IT!" after Hawk Moth finally reveals who he is. Then he Akumatizes himself.
Dark Owl started as what seemed to be a lighthearted filler episode, and then the following things happen in succesion: Dark Owl imprisoned Ladybug and Cat Noir, threatening to kill them unless they hand over their Miraculouses. Ladybug and Cat Noir unmask in front of each other, but keep their eyes closed the whole time, causing Tikki and Plagg to not only see each other but see who the other hero's secret identity is. And in the final standoff in Monsieur Damoclès' "lair", Dark Owl succeeded in pulling an earring off, causing Ladybug to start detransforming right there and then. The fandom just about had a collective meltdown.
"Zombizou". SO! Did you want an in-series confirmation that Marinette and Adrien weren't immune to Akumatization? Well, you're in luck! Besides that, Miss Bustier becomes the first person to try and resist the akuma's influence after keeping it from infecting Marinette, Chloé gets some actual Character Development, and we get further confirmation that Hawk Moth/Gabriel's goals involve bringing back Emilie!
The "The Queen's Battle" duology. Hoo boy. Between the two episodes, we get the following: Chloé getting the Bee Miraculous and quickly breaking the rules by transforming in front of others (including Gabriel); the reveal that kwamis are seriously overpowered (with Plagg unleashing a Cataclysm that, in the past, apparently wiped out the dinosaurs); the reveal of Chloé's mother in all her bitchy glory; Gabriel almost giving up his pursuit of the Miraculouses, and Ship Tease between him and Nathalie; the current location and condition of Emilie Agreste; and a confirmation that, not only can people get akumatized more than once, but Miraculous holders aren't immune...even if they're transformed when the butterfly is sent after them.
"Catalyst", period. Highlights include Volpina back in action; the first time an Akuma voluntarily leaves its target; illusion Cat Noir being killed by Akumatized illusion Ladybug; Hawk Moth empowering himself via his latest villain which leads to the return of a majority of the past Akumatized villains; and the very first time all five of the Miraculous holders gathering to battle!
The follow-up episode, "Mayura" is no slouch either. Hawk Moth is finally fought head-on; Nathalie dons the Peacock Miraculous (becoming the titular character), which reveals both its power set and that something happened to it that now causes its powers to be Cast from Lifespan (which paints a good picture of what might have happened to Gabriel's wife to put her in a coma); and Marinette finallyacts on her feelings for Adrien!
"Ladybug". HOLY. SHIT.Hawk Moth brings back Catalyst and transforms into Scarlet Moth. He then proceeds to Akumatize most of Marinette's class, Sabine Cheng, and (thanks to Lila) Marinette herself, at least until Nathalie's health problems force him to withdraw the butterflies before Marinette gets transformed... which is good, because she'd started removing her earrings the second Hawk Moth gave his get-me-the-Miraculous speech. It bears repeating: Hawk Moth almost won. On top of that, what does end up being the plan of the week is darker than usual. Knowing the stakes and risking her life to become Mayura again, Nathalie puts so much power into a Sentimonster copy of Ladybug that once she loses the object the feather was placed in, which allows her to control the Sentimonster, it proves to be fully sentient. When she chooses to help the heroes defeat her former master, Nathalie simply withdraws the feather, causing the clone to vanish - this time, the death of a human being, or at least someone who was clearly as sentient as one, is not an illusion, not a case of Fridge Horrornote If you think about it, not everyone in Paris could've managed to get to high ground during "Syren", and things like people getting turned into glitter or ice cream don't seem reversible outside of Ladybug's Reset Button, without which this could be a much darker show. But, well, you're not supposed to think about it and there is the Reset Button., and not undone at the end.
"Feast". Not only do we finally learn Master Fu's backstory and how he became the last Miraculous guardian, we also find out that there are more Miraculouses that were eaten by the titular monster, only to be restored when it is defeated. And now Hawk Moth knows who Master Fu is, putting the heroes in more danger. Also, it turns out that there is no time limit on the ability of Ladybug's World-Healing Wave to undo akuma/sentimonster damage. When the title monster is defeated, the temple and all the other Guardians are restored after nearly 200 years! Mind you, that changes the heroes' status quo less than you might think. Hawk Moth still has the Peacock and Butterfly Miraculous, which means there will still need to be heroes to oppose him, so the need for our dynamic duo and Master Fu to keep up their activities and secrets remains.
"Cat Blanc". Holy shit, "Cat Blanc". We're treated to a Bad Future where Hawk Moth finds out Adrien is Cat Noir and takes advantage of the fact to Akumatize him. The end result? Cat Blanc kills everyone in Paris before flooding the city. Thank god Bunnyx managed to Set Right What Once Went Wrong.
"Heart Hunter" and "Miracle Queen". Chloé betrays Ladybug and joins Hawk Moth; losing her Miraculous permanently as a consequence. Thanks to Chloé, Hawk Moth learns the identities of almost all heroes except Ladybug and Cat Noir. He also manages to fix the Peacock Miraculous. Master Fu makes Ladybug the new Guardian of the Miracle Box, loses his memories and leaves Paris together with Marianne. Adrien/Kagami and Marinette/Luka grow closer, almost to the point of being Official Couples.
Good Lord, the ending of "Gang of Secrets". Marinette tells Alya she's Ladybug!
The series was animated to English scratch voice dialogue. Being redubbed with the official English cast led to some lines being just a hair out of time, all the more noticeable with the very well-pronounced mouth animation.
Paris — a popular tourist destination — is glaringly shown with only about fifteen different incidental characters filling up small crowds. While the show does have a higher budget than most cartoons, it would seem it burnt off most of the money on other special effects and ran out of budget for crowd scenes more accurate to real life.
Common consensus has it that the animation has taken a noticeable drop in quality since the start of Season 2.
Squick: Theo Barbot's infatuation with Ladybug can fall into this due to her being visibly in her mid-teens and him seemingly in his early-twenties. And even if you assume that people aren't supposed to notice the heroes' ages due to the magic of the Miraculous, the fact that he's also been linked◊ to the similarly-aged Mireille raises some questions. Eventually, Word of Godconfirmed that he was around 16-18, lessening this trope.
Starboarding: Some fans like the idea of Chloé having a crush on Ladybug, without necessarily having those feelings requited.
In "The Pharaoh" the professor is right to point out Don't Touch It, You Idiot! about the Staff of Anubis because ancient artifacts are delicate and can easily become damaged.
In "Darkblade", Armand D'Argencourt's seeming Sore Loser tendencies after losing the Mayoral election. Given his Humiliation Conga from his Jerkass opponent (Chloé's father, of course), it being a textbook Ironic Echo of said opponent's ancestors doing something similar to Armand's family long ago, and the public constantly hounding Armand for said loss, you really can't blame him for being so frustrated — and are probably surprised that he does nothing worse than Poke the Poodle (at least before Hawk Moth turns him into Darkblade) during his Rage Breaking Point.
Ladybug not taking Chloé's advice in "The Antibug." As she points out to Cat Noir, Chloé had lied to them earlier about her fight with Sabrina and was otherwise useless in battle as The Millstone and a bystander. She had no reason to trust Chloé's word.
Marinette in "Guitar Villain" when producer Mr. Ross wants her to design Jagged Stone's album cover to mimic that of XY's. Although Tikki tells her to stick to her guns and design it the way she would, Marinette has a good point in saying that Mr. Ross told her to design it a certain way; most graphic designers have to compromise their styles to satisfy clients. Marinette was just really lucky that Jagged had enough power as a musician to override what Mr. Ross wanted and tell Marinette to design it in her style.
When making her peace offering to Marinette in "Chameleon", Lila states that all their classmates are idiots. Considering how easily she manipulates them and some of the lies she gets away with, she may have a point. She also stated earlier that they ought to be friends instead of enemies because nothing good or productive would come from her and Marinette fighting over a boy, and given what happens when Marinette and Lila do officially become enemies, it's hard to see this as a lie when the sentiment seems so true.
It was revealed in "Catalyst" that Marinette's attempts to expose Lila's lying have so far been brushed off by her friends, who think she's jealous of Lila for having feelings towards Adrien. It's not hard to see why they think this, since Marinette's crush on Adrien often causes her to make poor decisions in scenarios relating to him (including her first confrontation with Lila), not to mention many of her antics have fallen into unhealthy stalker territory.
During the year and a half long hiatus between the end of Season 1 and the start of Season 2, a lot of future canon developments have been spoiled through con previews, leaks, and creator reveals. New character concepts and hinted plots have especially divided the fandom as the show adds more and more Game Changers. This has especially applied to the new Love Interests, Kagami and Luka, to the point that Brand Ambassador Ferisae had to reassure fans to give the characters a chance.
"Chameleon" was alienating fans even before it premiered, thanks to a preview clip of the scene where Marinette is forced to move to the back of the classroom. Naturally, the fandom's opinions failed to improve when the episode fully premiered.
Most characters such as Sabine, Marlena, Prince Ali, and Mireille have yet to receive their A Day In The Lime Light episodes.
While she's still a major Base-Breaking Character, a number of fans agree that Lila has been fairly underutilized, especially in season 3. In her first few episodes, it looked like she would take the Alpha Bitch role from Chloé after the latter went through a HeelFace Turn, with her alliance with Hawk Moth providing a number of story opportunities. Instead, Lila never really had any involvement in season 3's ongoing plot, and in a case of Shocking SwerveChloé ended up undergoing a FaceHeel Turn and being Hawk Moth's ally in the season finale instead.
Rose's subplot with Prince Ali was likely dropped after season 1.
Chloé's entire character arc has been considered one of these. While episodes like "Despair Bear", "Zombizou", and the Queen's Fight trilogy seemed to plant the seeds for a potential redemption, or at least her making the transition to a Lovable Alpha Bitch, she failed to retain any of the lessons she learned from these episodes, and ended up becoming even worse in season 3, to the point that she willingly worked with Hawk Moth when Ladybug (understandably) refused to give her a Miraculous again. To add insult to injury, all of this meant that Lila — whom many fans agree is a more interesting antagonist — was pushed to the background, even though it's already been established that she's a willing ally of Hawk Moth. To say that many fans were frustrated would be an understatement.
"Mayura" has attracted a few complaints about the show bringing back akumas from previous episodes while not showing the heroes had learned anything from those battles. One example is when Rena Rouge gets hit by one of Dark Cupid's arrows. In the villain's debut, it was shown that true love's kiss could reverse the effects, but Carapace (despite being Rena's boyfriend) never thinks to try it, leading to both of them being akumatized.
Some fans who were disappointed with the season 3 finale wished that "Ladybug" or "Cat Blanc" took its place instead; after all, what better way to give us a high-stakes finale than getting one of the main characters akumatized?
The Season 3 Finale ends with Adrien dating Kagami, and Marinette dating Luka. Season 4 Episode 1 opens with Marinette's Ladybug double-life straining and finally ending her relationship with Luka, while the following episode had Adrien and Kagami breaking up for similar reasons (and unlike Luka and Marinette, their friendship was strained as well). Regardless of where you stand on the shipping wars, it does beg the question why have Marinette agree to date Luka and Adrien to date Kagami at all if their relationships were going to end immediately after that? Even fans who don't support those pairings and/or the fans who guessed that they would break up eventually didn't expect that those pairings would last as little as they did.
Tough Act to Follow: The Season 2 finale two parter "Heroes' Day" is considered one of the best episodes of the series so far for its sheer epicness... though maybe, it's a little too epic for its own good, given that many fans wondered what other seasons could do to top it. And indeed, after the Season 3 finale "Battle for the Miraculous" was seen as lackluster in comparison, a lot of people looked back at "Heroes' Day" and thought that maybe they should have saved it for the Grand Finale.
Papillon/Hawk Moth, due to his extremely tight face mask, thin face shape and huge eyes making him look decidedly... off. Considering he's the main villain of the series so far, this may be on purpose. He looks especially creepy in "Dark Owl".
Rose falls into this sometimes due to her enormous eyes, which are overly large even compared to the already large eyes of the rest of the cast.
Chloé can also be this since some of her expressions, specifically the ones where she narrows her eyes, unintentionally make her skin look really tight and plastic-y. Though some Fridge Brilliance kicks in when you consider she's exactly the sort of person who'd have a lot of "work" done on her face.
The photo Adrien has of his mother as his desktop background, which is clearly his mother's head superimposed on Tara Strong's body, meaning she's a cartoon head superimposed on a human body.
Prime Queen's design is great and all, but there is just something off about her, especially the face. It really works.
Auguste, the baby in "Gigantitan". He's remarkably ordinary in design except for having extremely bright green eyes, almost neon-colored, giving him a slightly artificial and off-setting appearance.
Due to the (lack of) detail on some of these models, this moment◊ from Gorizilla is especially unsettling.
A few people have been put off by Luka's apparent lack of eyelashes.
Audrey Bourgeois, in part due to only having eyelashes on the outer halves of her eyelids, and having lower quality eye textures.
XY in "Guitar Villain". Jagged and Marinette dislike him for being "young" and considered a better musician, having overtaken Jagged on the music charts, and XY makes some catty remarks about Jagged Stone being a dinosaur. With that said, his fear when Guitar Villain kidnaps him and makes him Walk the Plank at the Eiffel Tower makes him endearing; he is also very childlike in his maturity and has a human reaction to Jagged after Ladybug purifies the latter.
Kagami Tsurugi. We're supposed to be rooting against her because she's yet another obstacle to the Love Square, and consequently that Marinette's actions against her are justified. However, she's nowhere near as bad as Chloé or Lila; she's a Jerk with a Heart of Gold at her worst, and she's perfectly willing to be civil with Marinette, which makes all of Marinette's plans against her (including teaming up with the aforementioned Chloé at one point) just look like mean-spirited bullying. As of "Ikari Gozen", this tropes seems to have been played deliberately; Marinette realizes her attitude towards Kagami has been way too harsh and ultimately befriends her.
Chloé Bourgeois. Word of God is adamant that she's Beyond Redemption, but a number of fans think differently, pointing to the various times she was capable of being nicer in the show (even if they never stuck) as proof. As such, her sudden FaceHeel Turn in the season 3 finale (followed by the aforementioned statement by Astruc) was considered highly jarring to these fans, since a number of her actions beforehand seemed to point towards her getting a redemption.
Lila Rossi. Like with Chloé, Word of God stated she's meant to be a Hate Sink and completely unsympathetic. Some fans, however, feel that her actions are at least rooted in a Freudian Excuse (whether it's the fact that Ladybug publicly called her out on her lies, the idea that Hawk Moth is manipulating her, and/or the prolonged absences of her parents), thus making her at least slightly more sympathetic than the writers intended.
Marinette/Ladybug in the season 3 finale. While her picking Kagami over Chloé to wield a Miraculous was presented as her merely trying to get the former away from Adrien (thus resulting in the latter pulling a FaceHeel Turn), several fans have pointed out that Chloé has done absolutely nothing to become a better person since getting the Miraculous the first time; therefore, giving a Miraculous to Kagami made more sense no matter what Marinette's reasons were. It doesn't help that Word of God admitted Chloé was meant to be irredeemable, yet the episode still implies Marinette made the wrong choice.
The Un-Twist: Gabriel Agreste being Hawk Moth was so blatantly telegraphed throughout season one that a portion of the fandom didn't believe it was going to be true, since it was far too obvious to be considered a twist. Turns out that the show was just being very heavy-handed, and dropped The Reveal rather unceremoniously in the first episode of the second season.
Trixx was introduced to Miraculous fans outside of the context of the show and was mistakenly believed to use she/her pronouns until Trixx' introductory episode where viewers were slightly shocked to hear an unmistakably male voice.
Duusu was initially believed to be a girl (despite being based on the male version of an animal) because he's referred to as "she" in "Sandboy". However, that was stated to be a dubbing error and Duusu is actually male.
The other Kwamis also fall into this, as the tiny creatures all have high-pitched voices that make it hard to tell, and actually, they're all sexless, being personifications of whatever it is they represent. Not even the visible eyelashes that some of them have make it easier to tell, and it doesn't help that some of their genders are different across dubs.
Visual Effects of Awesome: As noted on the main page, the CG version of Miraculous Ladybug was produced for $11.5M, more than most Western productions. This has blessed the show with highly-detailed visual design, dynamic battle choreography, expressive animation and particle effects.
Adrien, who is a Stepford Smiler about his home life, does a suffocating modeling job to make his dad happy but leaves no time for him to hang out with his friends, and crushes on a Magical Girl whom he thinks is better than he is and rebuffs his romantic gestures. Heck, in his birthday episode only one person remembered to give him a present and his best friend got turned into an akuma on his behalf.
Marinette. She's bullied at school constantly (by both Chloé and Lila), she has to deal with the fate of Paris constantly resting on her shoulders as well as her normal, also stress-inducing responsibilities on a daily basis with little to no free time, and she has to deal with her clumsiness and constant heartache over Adrien on top of that. Is it any wonder she ultimately breaks down during the season 3 finale?
Nooroo, the kwami of the Butterfly Miraculous, is enslaved by Hawk Moth and forced to aid him in a terrorist campaign against Paris. His relationship with Hawk Moth is routinely shown to be emotionally and occasionally physically abusive; he is forbidden contact with the outside world, not allowed to be more than a few feet away from Hawk Moth, yelled at whenever he questions his master's decisions, and he has had his mouth magically shut on two separate occasions when he has truly angered Hawk Moth. Finally, he is completely powerless to save himself and can only wait for Ladybug and Cat Noir to bring him salvation, and with the reveal that there's still a Hawk Moth active in the future in "Timetagger", it doesn't look like that will happen anytime soon.
Jagged Stone's British accent conveys the kind of foreign rockstar appeal the American French accent goes for in the original. Seeing how they're all in France anyway, the reverse would just be awkward. In addition, since the character's name has obvious references to The Rolling Stones and Mick Jagger in particular, one could argue that a British accent would have been more appropriate to begin with.
There's an accent difference between how Lila's name is pronounced in French and in Italian (in French the accent is on the "a", but in Italian is on the "i"). In the Italian dub, most characters pronounce her name the French way, with only the rare Italians pronouncing the Italian way.
In "Sapotis", the original French has a doozie of aBat Deduction where Ladybug figures out that she has to go to Master Fu when Cat says hes too young to drink tea. The dub changes this line to My Kung-FUs getting rusty., which seems a lot more plausible for such a leap in logic.
In "Timetagger", among the future villains Bunnyx mentions is an Evil Counterpart to Majestia named Ignoblia. In the English dub, she's said to be Majestia's evil sister; in the French dub, she's Majestia's akumatized form.
In the French version, Cat Noir's nickname for Ladybug is "Buginette". The suffix "ette" in French means "little", so it literally means "little bug". However, English viewers would probably find it suspicious that he would just happen to pick a name that's so similar to her real name, Marinette. Thus, in the English dub it was changed to "Bug-a-Boo".
