Sasha Blouse from Attack on Titan really suffers from this: despite being a well-fleshed-out character with hopes and a personality, an excellent soldier, and something of a badass, the vast majority of fan art and references have to do with her undying romantic love for potatoes. Because she was introduced by comically eating a potato. Granted, the other cadets called her "Potato Girl" for a bit, but that died down after their three years of training with her. But Jean brings it back up again in chapter 51. Even acknowledging that her gluttony is one of her most prominent traits, she's actually much more obsessed with meat.
Bleach has Orihime. You get kidnapped by the Arrancar ONCE, and suddenly, you're the Princess Peach of anime. Even Kairi didn't have it this bad.
Not to mention, it just wasn't a mere kidnapping. Ichigo and the others were barely recovering after a huge battle that they lost, Orihime was trying to cope with her feelings for Ichigo and her recent depression over feeling left behind. She does fine for a bit, with Rangiku helping her to deal with her jealousy of Rukia and Rukia herself taking it upon herself to train Orihime for the fight with the Arrancar. It was only after that when Ulquiorra came with the Sadistic Choice. The radical detractors of Orihime's character basically threw every insult they could at her and wanted her to die, but other sides of the fandom were disappointed that, in their view, she folded after promising to herself that she would no longer be a burden to Ichigo and fight alongside him and everyone else... (Though she ultimately managed to get out of the pit and, in the Vandereich arc, she finally got to fight alongside Ichigo and the other True Companions — without folding. Tragically, by that point, her rep had been solidified for a good eight years.)
Orihime's screams for Ichigo to help her know what to do during the climax of the Lust arc is most likely the biggest Never Live It Down moment for Orihime in the entire fandom. Say My Name is a VERY common trope in manga as a whole and Bleach isn't an exception, many other characters have also screamed each other's names at least once per chapter, and Orihime only took to screaming it repeatedly when she was having a massive meltdown. However, to a loud part of the fandom, that simply doesn't matter: Orihime can't even mutter Ichigo's name without fandom calling her "whore" and "clingy", whereas everyone else can get away with it.
A good chunk of the negativity comes from just how long she was captive.
There's a scene in the second season where Schneizel engages Lelouch in a game of chess, which became infamous all over the Internet when Schneizel moved his King next to Lelouch's, which is illegal AND impossible in chess. This tends to get portrayed as the writers being idiots who know squat about chess...ignoring that the actual game was already over and Schneizel was just testing Lelouch to see what kind of leader he is.
Princess Euphemia is likely going to be forever remembered for slaughtering thousands of innocent Japanese under the influence of the Geass, never mind that she would never do such a thing of her own volition.
Crayon Shin-chan: Misae Nohara suffers through this for her infamous hypocritical behavior towards her husband Horoshi. She would beat him either if he flirts with random women or for trivial reasons. She is also known for constantly striking their son, Shin-chan in the head whenever he misbehaves.
No matter how much more of the comparatively tame materials see release Stateside, Cutey Honey has never quite been able to shake its reputation in the American fandom as a hentai series ever since the first official release to hit the States, which was of the Hotter and Sexier (not to mention Bloodier and Gorier) OVA series New Cutey Honey.
Lenalee from D.Gray-Man suffers from this. No matter how many Akuma she defeats, it seems she'll always be best known for that one time when she was Brought Down to Normal after a massive fight (that she did win anyway), and became unable to fight for a while. Even after she recovered from her injuries, got her powers back and curb-stomped a Level 4 Akuma, fans didn't stop portraying her as a whiny Damsel in Distress. What makes it even worse is that Allen went through the exact same thing, but nobody bashes him for it.
TV Asahi will likely never hear the end of that one time when they censored the national anime of Japan after they partially obscured a single vacuum-induced Panty Shot in the 2013 film Doraemon: Nobita's Secret Gadget Museum ~Museum Adventure~.
When Vegeta crushed his scouter after it was unable to register Goku's power level, famously accompanied by his declaration that it was "Over 9000!"note "Over 8000" in Japanese. It has long since spawned a meme about Vegeta shouting random numbers and crushing electronics he's holding.
Vegeta's distaste for worms in a filler episode of the Majin Buu Saga. Fans always make jokes and many photos on DeviantArt about his dislike of worms along with Goku's fear of needles.
Krillin is often mocked because he dies a lot. While he does die 3 times (4 counting Dragon Ball GT), there's another character who dies just as much, but never gets brought up: Chiaotzu. However, Krillin's first two deaths were important, memorable events that had a lot of emotional impact, the non-canon fourth one like this too, and only the third was minor (Albeit the anime made it a bit better). Chiaotzu's first two deaths were Senseless Sacrifices, and the third wasn't even pointed out, just inferred. But nobody remembers this. It should be noted that if one discounts GT and counts Dragon Ball Super, Goku himself has died the same amount of times as Krillin. Of course, he gets a pass, given that he's Goku and his third death literally lasted a minute and was in a Breather Episode.
Krillin's subsequent deaths are far more notable because he was revived with the Dragon Balls once already (and before they came up with new rules, the Dragon can only revive a person once). Krillin effectively cheated death twice, first by being revived and again when his friends circumvented the 1 revival rule. This may have contributed to his dying being memetic. Still, the same things could be said of Chiaotzu (As they die at about the same time; hell, Chiaotzu's second death comes well before Krillin's), but the show focuses more on Krillin, so it's understandable he's remembered more.
Counting all the series, Android 17 and Piccolo have also died four times, but nearly all of Android 17's deaths were offscreen, so it's hard to remember.
Yamcha is often noted for dying to the Saibaman enemy's Suicide Attack, but fans often neglect to note that he was canonically taken off-guard and in the manga had no time to react at all. Fans also tend to ignore that as stated in the series, Yamcha also went ahead in the fight as a favor for Krillin who had already died once and thus couldn't be revived by the Dragon Balls, instead believing Yamcha was doing it for the glory or selfish reasons (see Ron the Death Eater). Yamcha's Undignified Death has become so well-known in the fanbase that it's largely the thing he's best-known for. His pose upon dying is an Ascended Meme, with multiple video games making him unusually vulnerable to the normally-ineffective Suicide Attack of Saibamen, and in Dragon Ball Xenoverse, falling into the "death pose" is actually a move of his. It even crops up in Dragon Ball Super. By Dragon Ball Fighter Z, the joke had become so universal that it even got subverted, as Yamcha naturally has a Dramatic Finish when defeated by Nappa... but he can also return the favor, defeating Nappa in exactly the same way.
DBZ is often poked fun at for its dragged out fight scenes... However, the only time it was really as bad as the jokes made them out to be were during the Namek Saga. Other times were not as bad.
At the end of the Saiyan Saga, Chi-Chi was completely neglectful of Goku, caring nothing for his health and only showed concern for Gohan. This is what most fans best remember her for, and will use this incident as a supporting point in arguments on whether she's a good wife for Goku.
Mr. Satan has yet to live down taking credit for beating Cell. Despite him redeeming himself by helping Goku save the world from Kid Buu, fans still wont let him live this down.
This is pretty much intentional though, since even in Toriyama's version (non-GT), he is portrayed as being all too eager to protect his inflated reputation. (as shown when he risks DEATH in a match against Trunks in a later tournament). Toriyama sort of subverted/played with this, in the final arc, the super Genki Dama is only successful due to Satan having inflated his reputation to the extent he is famous worldwide as savior of the world, whereas 99.99% of Earth's population is "Goku? Who is Goku?". A case for "humility isn't always a good thing".
Goku gave Cell a Senzu Bean and threw Gohan into a fight with him, with Gohan being helpless and scared at the time. This incident is mentioned a lot when fans question his nobility and his good nature in general, ignoring all the times he protects Gohan. It's just that he thought the kid was ready when he really wasn't, and did not understand that Gohan wasn't the Blood Knight his father was. Goku has yet to live this down.
Comic shop owner Miami Mike was immortalized in an infamous credits potshot from a Ctenosaur Video fansub of the series for doing something to a Ctenosaur person at DragonCon, revealed in March 2018 to be stepping on Ctenosaur's toes via sale of their tapes.
Dragon Ball Z Kai is sometimes thought to be heavily censored. However, this isn't the case - while the original version does have some censorship (the scene where Piccolo blows a hole through Goku and Raditz is edited and shots of genitalia and Flipping the Bird are removed), it's largely negligable. This mistaken assumption can be largely attributed to the original broadcasts done on Nicktoons and Toonzai, which were heavily censored, removing blood and profanity, and, in the latter's case, removing all references to death and making Mr. Popo blue. However, the Toonami and home versions of the show don't have these changes, and when one compares the English dubs of the original show and Kai, Kai is much less censored.
In the Durarara!! novels, a new character is introduced named Aoba Kuronuma. There is no official artwork of him, however he has shown up a lot in fan art. How? Because he's most remembered by being stabbed with a pen by none other than Mikado and is always drawn with a bandage on his hand. He has shown up as of the second season of Durarara.
An incredible amount of Fairy Tail fan art dedicated to Zeref has him in tears. While he did cry during one scene, he then went on to take down two of the biggest Jerkasses in the manga's history, one while giving a speech on how the man is a worthless scum who has wasted his life. The manga also spent 200 chapters throwing out occasional references to what an absolute monster he was prior to the events of the story. Much of what isn't him crying is still him clinging to Natsu and looking mournful.
Sting of the Sabertooth Guild is widely regarded as a Memetic Loser for simply surrendering at the end of the Grand Magic Games, instead of taking advantage of their weary condition as we had been led to believe he would do. This is mostly because he started off as a Smug Snake, even though he has become much more likable.
The Familiar of Zero: The infamous scene where Louise beat up Saito with a horse whip and we see him unconscious bruised and bleeding. While Louise's treatmentof Saito as a whole has been quite the point of contention, that particular scene stands out, probably because having a character actually bruised instead of covered in, say, cartoonish bumps make it hard to take the scene as slapstick violence.
Yamakan's disastrous anime Fractale not only failed to sell well but it became the new running gag for "Saving Anime Line" and torpedoed Yamakan's career and anything he touches.
There was one instance in Fullmetal Alchemist where Colonel Mustang is seen slacking off at work and avoiding paperwork until the last second. This wasn't even a very important episode, just a little fanservice since he hadn't shown up in a while. However, try to find ONE Royai fic (or even just a fic about the colonel in general) that doesn't at least mention this 'tendency'. Just one.
Author example. Al hides a kitten in his armor once, and this is repeatedly parodied in the manga omakes (for example having an enormous cat that breaks out of the armor or multiple cats that claw Marta when she tries to hide in there, resulting in Al recovering his memory of being at the Gate).
In one of the GBA games a sidequest involves him finding and collecting dozens of cats, all of which boost the power of his special attacks where he releases a swarm of them to maul opponents.
Fushigi Yuugi as a series is prone to this. What plot? What Coming-of-Age Story? All most fans remember is Miaka and Tamahome screaming each other's names, pretty boys and attempted rape.
Miaka is only remembered as "that dumb bimbo who eats a lot and makes all the pretty boys fall in love with her". As if she never did anything else. Yui? Oh, she just went Yandere for Tamahome and tried to kill herself. Suboshi gave Amiboshi a Medicine Kiss, so obviously they're canonically doing each other. Soi sleeps with Nakago, Tasuki sets everything on fire, Chichiri says "no da", Nuriko's gay, Tomo wears makeup, let's stop here, shall we?
In Ghost Hunt, Naru is shown drinking tea maybe 3 or 4 times in 25 episodes, and other characters are often given tea as well when they come into the SPR office. The fandom, however, always portrays Naru as a tea addict. Find one fanfiction featuring Naru that does not mention tea multiple times, I dare you.
Before the Anzio OVA was released, Anchovy was shown in the manga as obsessed with victory and harsh toward Miho, which is how she's most often portrayed.
Averted with Anteater Team. They only join in the Final Battle and their sole contribution to it is being taken out almost immediately, by accidentally reversing into the path of a shot aimed at Anglerfish Team. In fan works, they typically have at least a passable understanding of how to fight, even if they're not one of the better teams.
While some people are starting to warm up to Shiho after Der Film, a large number of fans mainly remember her for 1) scolding her daughter for sacrificing a victory to save lives, 2) announcing that she's going to disown said daughter (quite a few fanfics have Miho's disownment as a plot point), and 3) calling any way of tankery besides hers "heresy."
Quite a few fans who haven't read Little Army or saw Der Film tend to conclude Maho is a textbook Aloof Big Sister, rather than a more complex and sympathetic character who actually cares for Miho.
Kageyama in Haikyuu!! and his love for milk. He is seen drinking milk or buying milk from a vending machine a few times in the series in passing. It is never talked about nor emphasized enough but looking at the fandom you would think he'd crumble down and cry without his carton of milk.
Mikuru herself is a Time Traveler with a significant role in The Movie of book 4 (the most popular volume). But, for some reason, people's memories tend to fixate on either that time Haruhi forced her into a Bunny Girl costume—not only are there official figurines of this, but embarrassed bunny Mikuru is also in the page image for that trope—or the scene where she told Kyon about the mole on her breast. The latter is especially unfair to teenage Mikuru, who technically hasn't done it yet.
Hetalia: Axis Powers has a case that's odd in that it's based on an event that hasn't even been shown in canon. As the series' characters are Anthropomorphic Personifications of nations, their characterization in fanworks are often based to some extent on real-life historical events that their representative nations, which is pretty much inevitable as it's impossible for canon alone to delve completely into the nations' histories. But sometimes certain writers may dwell on these events too much to strain the relations between characters who get along fine in canon, or worse, even if the event in question no longer affects the real life nations in question. Though canon Hetalia has been known to do similar things (e.g. England and the Revolutionary War), it gets especially noticeable and even somewhat jarring when neither the canon characters nor the real life citizens of the countries care anymore.
APH fanon in general tends to be inundated with this. Especially in the Japanese fandom. As many fans got into the series through the anime and may not keep up with the comics, or merely read only the early strips, they often tend to use outdated characterizations, despite the fact that Characterization Marches On may have phased them out.
France being a Quagmire-esque rapist/pedophile. He is indeed shown doing... unsavory things towards younger characters in older strips and borderline to actually sexually assaulting many others (in the Hetalia Gakuen game, he even drags poor Seychelles away with the game heavily implying hes going to force himself on her), but this has largely been phased out, in favor of him being a somewhat melancholy romantic who likes to flirt a lot and values consent deeply in his sexual conquests. The fandom has also largely moved on from it... well, the western fandom at least. A lot of the Japanese fandom meanwhile tends to still cast him as a creep or even as a straight-up stock Hentai protagonist.
Spain also gets this too. Fanon likes to think he's a yandere or a Cute and Psycho because of unpleasant elements of Spanish history and the fact that Hidekaz Himaruya said in his notes that he was originally going to be a two faced character like Russia that was only kind toward Romano. Himaruya mostly discarded that idea many years ago, but decided to play upon it on the 2011 Fool's Bath where Spain seems to snap at France when he revealed who the culprit was (which was indeed Spain, who sent the threatening letters to everyone and if they didn't come to this location at a certain time, he would reveal their most embarrassing picture of them). However when Spain appears to take his anger out on America and England, he switches back to his cheery self and explains that he just wanted to hang out with everyone and France twisted the words of what he really wanted. It was obvious that his anger was because he was drunk, but the fans now declare that he is officially yandere / Cute and Psycho despite it being Played for Laughs.
Another popular perception was that Spain is a pedophile due to the fact that in older strips he acted rather... oddly towards Child!Italy/Chibitalia (and common perception was he acted like this towards Romano as well due to the popularity of the Spamano ship), in one comic strip even anally penetrating the poor kid with his finger, though its implied that he didnt fully know what he was doing. The comic has been deleted, and Spain doesnt show this questionable behavior anymore, but it still lives on in Fanon, even if to a lesser extent than it used to.
Poland; he crossdressed all of three times in the entre webcomic, none of which were recent and one of which was deleted from the site due to Old Shame, but fandom seems to love putting him in skirts near-constantly.
A couple older strips and the anime had jokes involving Canada being unnoticeable, with only one of them making him explicitly invisible. He does not bring this up that much. In his vast majority of appearances, everyone sees him just fine, even if they occasionally think he is America (and even that only seems to really bother him when he gets beat up because of it). Recent strips, in fact, show him as being popular even; in the 2011 Halloween event all the other nations saw and recognized him just fine and cheered for him. Yet fandom still portrays Canada as the poor little nation nobody ever sees or even remembers the existence of, he is always whining and angsting about that (often to super-emo extents), and it's sometimes mixed with different degrees of America bashing.
Taiwan is a PluckyGenki Girl who gets along with almost everyone but China and even then she helps China when needed (though her methods are... unorthodox.) People only seem to remember that she once told China "leave Japan ALONE!" in a single-panel sketch, however, and thus they tend to believe that either she's a Clingy Jealous Girl to Japan (when she has never clung to him in the canon strips) or that she truly loathes China (when their relationship is actually much, much friendlier than it would be if Hetalia was super close to history).
Ukraine and Belarus's song Carrots and Sticks plays the Yandere archetype for laughs and makes some throw-away allusions to Ukraine possibly also loving Russia in a way similar to Bela's, only more passive-aggressively. Now some people seem to think that Ukraine is 'totally a super obsessive yandere, despite how this supposed "darker side" of her never really arises in the strips/series.
Because of being an obscure character, Bulgaria will always be remembered as that guy who smacked Italy with a stick in his anime debut, purely because he he felt like it.
While most Higurashi: When They Cry characters can, and have, gotten past their violent reputations and their respective arcs, Shion Sonozaki is still most well-known for her acts in Meakashi. It seems like most fans don't know, or care, about the fact that her personality isn't like that. It doesn't help that Shion is Yandere (in the anime, at least, since it skips out on an extremely important Inner Monologue from the visual novel about her true motives near the end of her arc), though not to the level she is when Hinamizawa Syndrome is involved.
There's also the case of Rena Ryuugu, who is perceived by many to be the series' trademark Ax-Crazy, Cute and Psycho, cleaver-wielding girl. The truth is, she is only truly like this in the sixth arc; her psychotic behavior in the first arc was merely a hallucination out of extreme paranoia by its main protagonist, under effects of the Hate Plague.
In fact, the entire franchise will never live down having oodles of gory murder scenes.
Remi from Horimiya is usually remembered for her first appearance when she blamed Hori for losing a book for the student council (when she was the one that lost it). This despite the fact that all of her subsequent appearances showing the two to be on good terms.
Discussions of Gon's morality will inevitably bring up his unquestionably lowest moment in the series: threatening to kill Komugi, an innocent, disabled, confused little girl who he was essentially holding hostage, if Pitou dared to delay him. His nightmarish expression made it clear he wasn't bluffing (not to mention he had previously come very close to attacking Pitou who was mid-surgery on a critically wounded Komugi, only stopping because he realized he needed Pitou to live rather than any concern for Komugi's wellbeing). This is made even worse by the fact that he never addresses any of this while recounting the events of the arc later on, and by the fact that much earlier in the series he chastised the Phantom Troupe for... killing people who have nothing to do with them.
Whenever Gon and Killua's friendship is discussed, fans will always remember the time Gon harshly criticizes Killua's behavior and tells him "It means nothing to him/It's none of your business" when Killua did everything to help him. Adding his morality above, many fans never forgave Gon for hurting Killua's feelings and began to label him as a selfish and toxic friend while simultaneously turning a blind eye to Killua's Poisonous Friend tendencies. Many also forget that he was slowly breaking down from guilt for Kite's death or don't realize the reason why Gon lashes out to the latter is that he has nowhere to direct his anger due to the circumstances and he was never told what Killua did for his sake in the entire arc.
Inuyasha: fan perceptions of Kikyo are heavily colored by her initially vengeful behavior after she was resurrected against her will, the most infamous example being when she tried to drag Inuyasha to hell with her, plus at least one attempt on Kagome's life. In fact, these events occur fairly early in the series, and Kikyo gradually mellows as she lets go of her misdirected anger and turns her focus toward defeating Naraku. A substantial camp of fans still have yet to forgive her for it, however, especially given the fierce Ship-to-Ship Combat between Inuyasha/Kikyo and Inuyasha/Kagome shippers.
Kakyoin Noriaki is a loyal companion with a sufficient Character Development, but he's mostly known for hunting for hot moms and licking a cherry in an extremely weird way, the former coming from him admiring Jotaro's mom once, and the latter of which is done by someone impersonating him (though he does end up performing it as a Brick Joke at the end of the arc).
Many fans like to joke about how the TV broadcast of the anime constantly censored any instance of the 17-year old Jotaro smoking, yet were completely fine with showing nudity involving the much younger Anne and Mannish Boy.
While the series isn't a stranger to violence against animals (usually dogs), Iggy being repeatedly kicked to death by Vanilla Ice is often seen as the pinnacle of this, and is the one that stands out in many fans' minds.
Killer Queen's Off-Model debut in the anime is often remembered by detractors of the anime, despite the fact that cases of characters being Off-Model like that are rather rare.
Despite the fact that the event wasn't actually his fault, fans still like to make jokes about Josuke burning down Rohan's house.
Because of how unexpected and frankly silly the event is, Kira's accidental Death by Ambulance at the height of the climax is by far the most remembered thing about the Part's climax, to the point that the ambulance has even become a Memetic Badass of sorts.
Abbacchio's constant Jerkass attitude towards Giorno seems to be the most remembered thing about his character, to the point that many fan works turn it into his sole defining character trait.
Despite later translations of the manga as well as the anime doing a better job at explaining King Crimson's ability, fans seem to mostly remember it for how confusing the ability's explanation in early translations is.
While Jotaro's parenting skills aren't anything to praise, many fans like to exaggerate him into being actively neglectful of Jolyne. Alternatively, fans who view their relationship in a more positive light tend to exaggerate him into being violently protective of her.
While Pucci is only implied to have an attraction to DIO, fans tend to exaggerate said attraction into being his defining character trait.
If one only ever looked at Kill la Kill's fandom, they'd swear that all Mako Mankanshoku ever did was become president of the Fight Club and almost killed her friend Ryuko for wealth and power and be in a relationship with Ira Gamagoori. This is despite Mako having an effective (if bizarre) skill at pep-talking that helps Ryuko numerous times when she's in tight spots, and that she and Ira never quite got to a romantic relationship (albeit not without Ira having to loudly deny his obvious attraction to Mako later on in the story).
A darker example would be in the case of episode 16 of the series, which exposes the shocking twist that Life Fibers are an alien life form, but the moment that most people remember from this episode is the infamous "Bath Scene," which establishes beyond a shadow of a doubt that Ragyo is sexually abusing Satsuki and that she's been doing that to her daughter for her whole life, casting her past overly touchy interactions with Satsuki in a more horrifying light.
And she always tries diplomacy first. It's just that her opponents are never willing to just talk, so she has to force them to listen to her.
Ironically, the only character Defeat Means Friendship was played straight for was Fate and the only other character it was used for, if subverted, was Vita. The fandom would have you think that she beats the crap out of all of her friends despite befriending Yuuno, Chrono, Amy, Arisa (arguably not a Defeat Means Friendship), Suzuka, Hayate, among others without being locked in battle.
Interestingly enough, Dieci, whom Nanoha defeated quite easily, turned good, but the two of them have never been shown interacting after their battle.
Hayate's Cosplay Otaku Girl tendencies are also subject to a great deal of exaggeration, based off her designing the Wolkenritters' barrier jackets in a deliberate attempt to make "knight-like clothing".
Shamal's Lethal Chef tendencies tend to get exaggerated in fan works, despite Hayate suggesting in the first A's sound stage that her cooking has improved significantly and the Wolkenritter conceding that it's not as good as what Hayate makes, but it's "not bad." It doesn't help that the other Wolkenritter like to remind her about her mistakes. One suspects that the makers caught on when they included this scene◊ in The Battle of Aces.
First impressions are a large part of how a character is portrayed, and it's somewhat unfortunate that Cypha had to debut easily dispatching Signum while mocking her status as a knight.
Dozle Zabi only says "Once the Big Zam is mass produced..." once. And it's one of the most memorable lines in the series. Same applies to Ramba Ral's "This is no Zaku, boy! No Zaku!!!"
Char. One fleeting romance with Lalah, who was about 5 years younger, and an implied relationship with the slightly younger Haman and you're forever labelled a paedophile.
Mobile Suit Gundam SEED Destiny: If you listen to the internet, Lunamaria Hawke couldn't hit the broad side of a barn if she was standing inside it because she missed a shot on a civilian shuttle moving on a relatively predictable course. On the one hand, episode 7 establishes her as a lousy shot in person when she couldn't get a bullseye at the shooting range. On the other, her ZAKU's Weapon of Choice is a long-range beam cannon...
Also, she wasn't the only person to have missed the shuttle in other Gundam shows; in an episode of Zeta Gundam, Char tried to shoot down a fleeing shuttle (carrying Jamitov), but he missed as well. Also, in the Destiny manga adaptation, Shinn, Kira, and Athrun tried to shoot down a shuttle and missed as badly.
Even Kira Yamato isn't immune. Fans seem to have clung to the idea that he's actually a poor pilot that relies on Freedom's Beam Spam abilities and only sits in the corner letting his computer do all the work. This was only true in his first battle with Freedom, in which he does indeed use full burst mode for almost the entire fight, but that's understandable because he's getting the hang of it, and the show wanted to hammer "THIS IS FREEDOM'S GIMMICK! IT HAS MANY GUNS!" into the audience. But after that he mostly sticks to sabers and his one rifle (which doesn't use the targeting computer) and in fact moves around in battle quite a bit. He never uses his Beam Spam more than once or twice per battle after that, yet the fandom seems only remember him sitting in one spot and letting his computer do all the work for the rest of Seed and all of Destiny. Of course, this probably wasn't aided by the copious use of Freedom's Full Burst attack via Stock Footage.
This is also in part because in the first part of the series, Kira pulled some tricks with the Strike Gundam that even detractors will call clever. After he gets the Freedom, this pretty much disappears in favor of the aforementioned "beat viewers over the head with the fact that Freedom has lots of guns".
Athrun has also gained a measure of infamy because he self-destructed both his suits in Mobile Suit Gundam SEED. You'd think he blew himself up more times than he did enemy mobile suits.
Nena Trinity crossed the Moral Event Horizon of the wedding shooting. Then afterwards, things got rather worse for her and she's forced to lay low, be less psychotic, helping Wang Liu Mei and when she mistreats her, Nena starts with leaking information that Liu Mei withheld to the Celestial Being, saving many lives, and when Liu Mei got even worse, Nena snapped again and killed her. While she's definitely a nutcase and generally not caring about other people's life, she's able to do both good and evil, and she's got a really tragic existence too which, while not absolving her of ANY crime, does mean she is perfectly able to be pitied. Fans only remembered that one wedding incident and think that's all Nena ever did, thereby she's an unforgivable evil little bitch.
Every member of the primary cast of Gundam Wing has at least one minor trait or (in)famous moment that ended up being their standard fanfic portrayal. Sadly, this blatantly ignores the Character Development that sees the characters grow out of those attitudes, which in turn results in people savaging the series for having shallow, one-dimensional characters.
At the start of the series Heero is full of self-loathing and tries to atone by putting his life on the line constantly - so much so that an off-hand line of dialog ("Life comes cheap, especially mine") has become a tertiary Catchphrase. He also attempts to kill himself twice early onnote in Episode 1 he tries to activate a self-destruct device in his spacesuit but it misfires, and in Episode 3 he jumps out of a tall building and doesn't pull his parachute cord, but Relena shouting his name somehow convinced him to pull it close to the ground and in one of the show's more memorable moments, he self-destructs the Wing Gundam (to keep it out of OZ's hands) and nearly dies in the process. Shortly after this he undergoes Character Development and starts getting over his self-loathing, to the point where at the climax of the series he defiantly shouts "I WILL NOT DIE!"...but this all tends to get ignored by both fans and detractors, who portray him as suicidal from start to finish.
Because self-destructing comes up prominently several times throughout the show (the five Wing boys and Zechs all attempted it at least once, with varying degrees of success, and The Movie ends with them getting rid of the Gundams once and for all), it's essentially seen as Wing's gimmick, with video games like Super Robot Wars and Gundam Breaker giving the Wing Gundams the ability to self-destruct on command regardless of how useful this actually is in context.
Relena only yelled Heero's name out loud thrice in the series (plus once more in the dub), yet people bash her as if she finished every episode with a Say My Name scream. She's also treated as a Yandere or a Stalker with a Crush despite the fact that she went to visit Heero all of once and remarked about it a few scenes laternote "I've come all the way here just to chase after a guy. Are you surprised, Father? But I couldn't help myself; I wanted to see him so badly. Can you understand how I feel, Father? Heero's the support I need to have around until I can get over my sadness over you. But he keeps running away from me...". (She did track him down a second time, but that was because she was afraid he would try to kill himself and had something she thought would convince him otherwise.)
There are also people who claim that she's constantly being kidnapped and in need of rescue, rather like Orihime later on. Relena was kidnapped all of once in the anime (Endless Waltz), but people also tend to label her imprisonment by Romefeller as a kidnapping, ignoring that it was intentional and had a positive outcome. And late in the series, she's held hostage on the space fortress Libra, but that was a snap decision by the person responsible and done while ignoring the chain of command, rather than orders by White Fang's leader to detain her.
Relena might as well get an award for this, since even the first thing she ever says gets this. In the first episode she asks her father to "leave yourself a little bit of free time" on his business trips, causing some to call her an Attention Whore who demands that he ignore his very important work to spend time with her. This ignores quite a few things, like her father's obvious displeasure with the situation (he isn't happy when the Alliance comes to sweep him off to do more work shortly after they land back on Earth), and the fact that just four episodes later they're on another business trip and Relena handles Minister Darlian's being tied up with work much better.
Wu Fei is possibly the biggest victim of this in all of Wing (yes, even moreso than Relena). In an early episode he denigrates a female opponent, leading people to assume he's a psychopathic misogynist. Late in the series, he takes up the ideal of justice and becomes something of a Jerkass. It's typically ignored that there are reasons for his attitudes (Freudian Excuse, My Greatest Failure, and Values Dissonance from a strict, traditionalist Chinese upbringing), or once again that he gets over it.
Another often-cited complaint with Wu Fei is his hypocrisy, as some say his repeated statements about honor and fair fights conflict with his terroristic actions (like blowing up a dormitory full of sleeping soldiers in his debut episode). However, the show actually presents Wu Fei's internal conflict over his actions, particularly in the episode where Team Mom Sally helps pull him out of his Heroic BSoD.
The big problem with Wu Fei is that a lot of his characterization is centered around the death of his wife and how that affected his worldview. Some of you reading this just went "Wait, what? He had a wife!?" The anime never even mentions Meiran Chang, nor how her death weighs on his mind. This is only revealed in the Episode Zero manga, which goes into the pilots' backstories (it was planned to be in the anime, but got replaced by a Recap Episode due to production issues). With her taken into account, a lot of Wu Fei's more controversial actions take on a new, much more sympathetic light.
Wing even has a non-human example: The Leo mobile suit used early in the series has a reputation all over the internet (even on this Wiki) as being a shoddy piece of crap that falls apart if it's so much as breathed upon. Granted, it is a Mook Mobile that's 15 years old when the show starts, but Leos tend to do quite when not facing a Super Prototype, and going purely by the numbers they're are actually superior to some better-liked Gundam staples like the Zaku II. The main problem is that unlike the Zaku, the Leo never really got the chance to shine and didn't have a dedicated pilot like Char Aznable to show what they could do; the show's Char Clone Zechs Merquise only gets a couple of battles in his Leo (managing to simply stalemate the Wing Gundam in free-fall) before he pulls the Leos' Super Prototype, the Tallgeese, out of the museum.
Gundam Wingitself is an example of this, much like Fushigi Yuugi above. Because the show features Bishōnen characters prominentlynote The fact that all seven of the male leads have female counterparts, most of whom are their Love Interests, is conveniently ignored, many anime fans automatically assumed that it was nothing but Yaoi-bait and wrote it off as trash. This impression wasn't aided by the fact that the show attracted a massive Fujoshi fanbase, who tend to produce fanworks that ignore of the "giant robots" and "war between Earth and space" aspects in favor of having the boys fall in love and make out, while the girls either cease to exist or (as is usually the case with poor Relena) go crazy and/or die horribly.
Gundam Build Fighters produced a humorous example: In Episode 23, Ricardo Fellini's Gundam gets a Luminescent Blush when his girlfriend Kirara's Gerbera Tetra grapples it during an exhibition battle. After the episode aired, animation director Masashi Obari jokingly tweeted "Now I have to live with being the man who made a Gundam blush for the rest of my life..."
After a long time and a lot of Character Development, several fans still remember the fact Bakugou was Midoriya's bully and that he never apologized or faced consequences for it, which is still a Broken Base among the fans on why he hasn't even been called out on it by anyone yet and whether or not he should be. One particular example is the part where he told Midoriya to kill himself and hope he reincarnates with a Quirk. While he never says anything that terrible for the rest of the story, and Horikoshi says Bakugo wasn't meant to be this bad, many of Bakugo's detractors hold it against him to this day, seeing it as an act so heinous, they cannot forgive him. It's gotten a little better as Bakugou does eventually apologize to Midoriya for all the things he said and did.
On that note, the fandom also tends to make jokes about Midoriya himself, on his tendency to break his bones whenever he used his acquired Quirk, One for All. Along with all of his corresponding hospital/infirmary visits. Regardless of the fact that his control over his Quirk's overwhelming power has improved massively to a point that the aforementioned visits have certainly diminished ever since season 3.
The early dub for the anime involved a large amount of "believe it"s to cover for Naruto's peculiar speech pattern (appending "dattebayo" to his sentences). While this was reduced later on as the anime gained American popularity and eventually scrapped all together, many believe he says "believe it" every five words.
Naruto is usually seen as a Big Eater who regularly polishes off a dozen, if not dozens, of ramen bowls in one sitting. The incident that spawned this was when Naruto slugged back a dozen or so bowls while receiving a lecture from Ebisu, who was paying. While never stated, it's likely Naruto was just eating that much to screw with Ebisu.
Sasuke Uchiha's detractors who claim he was always an impossibly huge Jerkass, instead of just aloof and somewhat rude - mostly in response to Naruto and Sakura genuinely irritating him (he gets worse later, but this is about how he acted at the start). For example, many are quick to cite all the times that he's put down Naruto, but forget that Naruto is the same way towards him and much louder about it. People also tend to exaggerate how many times he's told Sakura she was annoying. He said it twice. Once when she actually was being annoying, and when he barely knew her, and the other time was him joking/being sarcastic when he was about to leave Konoha and goes to Orochimaru.
People who hate the Sasuke/Sakura pairing also tend to claim that he constantly tried to kill her, ignoring the fact that that only happened twice, they were enemies at the time and he didn't treat her differently from any other opponent, and that both times she either attacked first or was planning to.
Sai asked Naruto a few times when they first met if Naruto had male genitalia, as an insult no less. But from the way fans talk you'd think every other word out of Sai's mouth is penis, even as he runs around brandishing a measuring tape.
Neji was a total Jerkass to Hinata prior to his Character Development. Even after the development transpires and Neji starts very clearly treating Hinata with care, fandom still doesn't let go of his past misdeeds.
Particularly notable is the insistence that he's a "woman beater". When he fought Hinata, it was in a Chunin Exams match-up, officially moderated by jonins from the village, and she was fighting him just as hard as he was fighting her. It wasn't until she actively provoked him by pointing out the logical flaw in his beliefs (he claims destiny is inescapable, but refuses to accept his lot in life) that he tried to seriously injure her, and he was stopped by the Jonin that were watching before he could.
The fandom also tends to exaggerate Hinata's fainting spells despite the fact that she only fainted twice in the manga, (once while going into the hospital and seeing Naruto injured, and once while he unexpectedly walks up on her when she hasn't seen him in almost three years). It doesn't help that she is more prone to fainting in the anime.
Hiashi gets this treatment. While he was negative and apathetic towards Hinata for years he learns to respect her by Shippuden. Fans will constantly portray him as an evil abusive, sometimes sexually abusive, father who wants Hinata dead or considers her completely useless.
And as for Naruto himself...y'know that "Sexy No Jutsu", an actual, honest-to-goodness ninja attack that involves turning into an alluring female (and is a regular super in the fighting games)? In the manga, he does this a couple of times in volume 1, and it's a long, long, LONG time before we see anything like it again. (Mainly because it's not a serious ninja technique, it's just a bit of goofing around, an extremely rare luxury in the world of Naruto.)
She seems to be more temperamental in the anime, as in the manga, the angriest she gets with Naruto after the Search for Tsunade Arc is raising her voice at Naruto for not showing respect to Fukasaku. Sakura suffers from the same problem. Not helped by Character Exaggeration in the anime, where one of the more forms of Padding is "Sakura beats up Naruto for no clearly defined reason."
Kakashi very often suffers from this. He invariably teaches Sasuke the Chidori and all of a sudden he plays favourites and all he wants is to train Sasuke, while hating Naruto, ignoring that teaching Sasuke this was for Sasuke's own good beyond mere strength as a ninja, and generally Kakashi plays favorites the least out of the various sensei (like Gai with Lee, Asuma with Shikamaru, or Kurenai with Hinata.)
The Accidental Kiss between Naruto and Sasuke back in episode 3 still gets talked about a lot.
What about Orochimaru? Bite one boy on the neck and you're labeled a molester for life. It tends to be forgotten that biting on the neck is Orochimaru's method of giving the Cursed Seal to a recipient, and that Sasuke isn't the only one he's done it to.
Orochimaru's case isn't helped by the fact that fans often exaggerate his obsession with getting Sasuke's body for himself into a case of him wanting to rape Sasuke or groom him for sex, especially pre-Shippuden when Sasuke would have clearly been underage; typing in certain key-words in Google will give you a variety of results that show "proof" that the Snake Sannin is a pedophile. What isn't pointed out, however, is that Orochimaru's obsession with Sasuke's body is primarily so he can transfer his own consciousness into it in order to get the Sharingan so he can learn more jutsu more quickly, which has always been a main objective for him. In addition, he was particularly concerned with getting Sasuke during the Retrieve Sasuke Arc because his then-current body was giving out on him and he needed to do the transferal quickly (Kimimaro, an earlier candidate for the procedure, was rejected due to having a terminal illness, and in the end Orochimaru had to transfer into one of his random prisoners because Sasuke didn't reach him in time). Plus, Orochimaru had previously tried to do the same with Itachi back when the Snake Sannin was with Akatsuki, but got schooled by Itachi for his efforts.
There's plenty of things in Naruto to snark about, and a not insignificant number of them have to do with the ultimate Uchiha ninjutsu, Amaterasu. When Sasuke used it to try to capture the Eight Tails for Tobi, while it was writhing in fake agony, it accidentally hit Karin, and her coat caught fire. Sasuke's got high level reaction speeds and has complete control over his Amaterasu so he was able to extinguish it before Karin was burned, but nevertheless, it's become a meme that "Amaterasu doesn't work on people wearing black" (Team Hawk was wearing Akatsuki cloaks at the time).
It's come to the point where Amaterasu is considered to be the most useless ability given to the Mangekyo Sharingan. Detractors point out that it has never killed anyone, it burns slow enough to be removed, Killer Bee was literally faking it when he was hit by it, and its nothing more than a nuisance (Madara even calls it a jutsu beneath his notice) by high level ninja. The hype it got in the databook was so big it would have been impossible to live up to though (Amaterasu burning hotter than the sun after all).
In Boruto: Naruto the Movie, an adult Naruto is busy working, and sends a clone to attend his daughter Himawari's birthday party instead of going himself. Cue a huge portion of the fandom labeling him a neglectful father who doesn't care about his family despite the fact that Naruto trying to balance his role as a dad with his duties as Hokage is a major conflict in his adult life, while the fact that he loves his kids and wants to be there for them is constantly emphasized in next generation materials.
Boruto himself has fallen prey to this trope. Yes, he started out as a Bratty Half-Pint with simmering resentment over his father not being there in person for important events (such as the aforementioned incident of Naruto sending a Shadow Clone to celebrate Himawari's birthday party) and over Naruto just generally being busy with work instead of spending time with him. The thing is, though, Boruto eventually does get Character Development as he comes to better appreciate the importance of his father's work as the Hokage and becomes less selfish overall. However, certain sections of the fanbase will ALWAYS see Boruto as an Attention Whorepar excellence (something not helped by the fact that Naruto, who was also that way at that age, at least had an excuse for it, in contrast to Boruto who grew up more privileged) and will NEVER forgive him for his initial dismissive-to-the-point-of-disrespectful reaction to Naruto'spast (to the point of flinging Naruto's old jacket out a window). On a related note, there are some fans who will immediately point to Boruto's admiration of Sasuke despite the man being a (mostly) Disappeared Dad as a terminal case of Selective Obliviousness.
For the same reasons, nobody will probably forget Robot Girl Chachamaru's "winding" incident. It was even popular enough to get done a secondand third time. Pity how the OVA failed to translate this scene into audio-visual form.
From hearing the so-called "Fans" talk, you'd think all Neon Genesis Evangelion's Shinji Ikari ever does is sit around wangsting ineffectively and endlessly about his daddy and how he doesn't want to be an Evangelion pilot, only ever ceasing to do so to masturbate over comatose girls. Actually, he spends most of the series being a kind and helpful, if not very confident young man who risks his life to save the world in battles against reality defying Eldritch Abominations despite the fact that he's understandably terrified of them. He is also quite efficient in battle, so much that Asuka is jealous of him. You gotta forgive him for ending up as a mental wreck after his relationship with his father (which was never all that good to begin with) was utterly shattered, his best friend (Toji) was maimed (killed in the manga adaptation), his mentor/father figure (Kaji) was murdered which caused his mother figure/guardian (Misato) to fall into depression, one of his love interests (Asuka) was brutally Mind Raped, became suicidal, and was placed in a coma as a result, shortly while other love interest (Rei) pulled a Heroic Sacrifice to save him, all that while Shinji was forced to watch helplessly by circumstances he had no control over. Rei was then replaced by a clone that looked the same, but did not exactly act the same.Then, Shinji met a nice boy (Kaworu) that thought he was really awesome and wanted to be his friend (and possibly more...) — turns out he is actually the Monster of the Week and Shinji has to kill the only person who ever said "I love you" to his face. Did we mention that he still saves the world after this? After ending it, that is.
While Shinji is known for being a whiny Memetic Loser who constantly angst, Shinji, as a matter of fact, rarely ever angsts out loud, instead being mostly just brooding and quiet. If anything, Asuka is actually shown to be more angsty and emotionally unstable. Yet many people are more lenient towards Asuka.
As for Shinji's reluctance towards being an Evangelion pilot, it is not that overshadowing in the larger scope of the series, being a minor arc that only really last for about the first four episodes, with Shinji having a minor relapse in Episode 6. After that, it only comes up two times, the first being in Episode 19, where it just ended up forming the basis for a 10-Minute Retirement plot that only lasted for that episode, and then finally in The End of Evangelion, where Shinji spends most of the plot reeling from having crossed the Despair Event Horizon.
Also, Rei. The first episode to properly focus on her clearly establishes her as a Sugar-and-Ice Personality who does have emotions, but apparently, four episodes of sitting around enigmatically are enough to brand yourself as theEmotionless Girl.
Toji is known for being violent because of a fight with Shinji. Toji is normally a pacifist, and it relates to the same reason he picked a fight with Shinji: the reason he was pissed at him was how his sister was injured in an Eva battle.
Misato is often characterized as a crazy driver by fans due to a scene in the anime where she deliberately (and playfully) acted like one to give Shinji a scare.
Kaworu in the manga was introduced by strangling a kitten to death. This was never forgotten by fans.
No matter what character development they obtain, particularly after the Time Skip, there are certain people among the One Piece fanbase who see Nami as a pirate-hating complainer who bitches whenever she gets a bounty and Usopp as an utter coward.
James in one episode remarked that he wanted a doughnut once. In the show's earlier days, he seemed to be known for wanting doughnuts.
Same thing can be said for Pikachu and ketchup. He carried a bottle of it around for half of the episode "Showdown at Dark City" and was never seen touching the stuff again. It's still brought up in fanfics to this day, all because the scene was just too funny to forget.
The second episode of Advanced features Pikachu happily licking a ketchup bottle while Ash and May are eating.
The XY episode "Mega Revelations" had Korrina dip Pikachu's hand into some ketchup in order to get his pawprint. After she was done, Pikachu licked his hand in joy.
And then there's the ending theme Pikachu's Song, and it's all about his love for the stuff.
Ash, in one episode, complained about the idea of helping Team Rocket's Pokemon because "they're the bad guys". Fanon (particularly rabid Rocketshippers) has since latched onto the idea of him being a heartless Jerkass when it comes to Team Rocket, even going out of his way to hurt them or anyone else who would help them in any way.
Ashs Charizard gets a lot of fan backlash for being disobedient in general, but the worst moment, and the one he will never be forgiven for, is getting Ash disqualified at the Indigo League. Even after he gradually improved and started to genuinely develop a bond with Ash, fans refused to forgive him for his earlier attitude.
James crossdressed well over a dozen times but has almost completely stopped since Johto ended, and he was always Disguised in Drag. People ignore Jessie's also frequent crossdressing (she most notably does it in "The Misty Mermaid", where it even serves as the page image for our recap) and act like James has Wholesome Crossdresser tendencies. Even in the first couple of seasons, only about 10% of his costumes were crossdressing.
He'll never live down wearing inflatable breasts in the Missing Episode "Beauty And The Beach". On this website, him in a bikini makes up half the images on his character profile.
Despite all the accomplishments that Ash has done over the years, fans still think he's a great failure of a trainer because, until he won the Alola League (which was rather oddly made), he's never managedto win any qualifier tournaments. Even if more than half of those were because of something that wasn't due to his ability, like Charizard's disobedience combined with a persistent Team Rocket in the Kanto League or Tobias using Legendaries and Mythicals in the Sinnoh League.
Ritchie gets this for causing Ash to unfairly lose the Indigo League. This is despite the unfair parts were caused by everyone except Ritchie specifically Team Rocket for capturing Ash leaving his team exhausted save for Charizard, the judges for not giving time for them to recover despite this and ruling "fell asleep" as "knocked out" which has never counted before or since, Charizard disobeying Ash, Ash's friends showing him No Sympathy despite the circumstances being out of his control while Ritchie convinced the referee not to award him the match by forfeit giving Ash as fair a fight as possible.
While it has subsided since, Erika sometimes still gets a lot of flak for not allowing Ash in her gym to battle for the badge, due to him disliking her perfume when he and the others stopped by the shop earlier that day. Let's start counting: first, he was causing trouble in her shop that could drive her customers away, so she had legitimate reasons to get him out; second, it wasn't Erika herself who kicked Ash out of the gym, but her staff (and for what we know, they could have done so without her consent); and three, he got in cahoots with Team Rocket to sneak inside, and at this point he had to know they were up to no good. Some even forget that Erika not only accepted his challenge afterwards, but actually awarded Ash the badge without a victory just because he rescued Gloom from the fire (which considering the above, was partially his fault to begin with).
Ash's Greninja will never, ever live down losing by Alain's Charizard and its Blast Burn, which had the side effect of handing Ash his most infamous League loss. It had been hyped up for the entire season and it's an incredibly strong Pokemon in-game, but losing to an opponent while it had type advantage, and to a move that didn't make sense for a Mega Charizard X anyway, created countless jokes along the lines of Greninja secretly being the world's most flammable Water-type.
Ash only dressed up as Ashley once, but the fandom still seems determined not to forget it. (His crossdressing did become a Once a SeasonRunning Gag, though, with the other twerps sometimes getting involved either along with him or in his place.)
Pokémon Adventures has a reputation amongst Pokémon fans for being "edgy" and is frequently mocked for being seen as awkwardly violent and making characters into antagonists. A large portion of what people complain about - like the Arbok being cut in half or three Kanto gym leaders being made into Team Rocket members - count under Early Installment Weirdness. The series has been toned down considerably since Johto, though stuff like Norman being an Abusive Parent to Ruby and Shauna being made into a Little Miss Snarker still are relatively recent and are prime hate bait.
Did you know that Mami from Puella Magi Madoka Magica actually does more things in the series than using the Tiro Finale and getting her head eaten? Because from the way the fans talk about her, you'd think that was all she ever did. Even the official merchandise is getting in on it - a lot of it includes the Witch who killed her in some way. It also doesn't help that in the Portable game her witch form is small enough to be bite-sized.
And, of course. There's Homura. In canon, she went through hell, going through a "Groundhog Day" Loop to find a way to save Madoka. In fandom? She's a hugepervert, usually wearing Madoka's panties over her head while trying everything to molest/spy on her. It does sometimes look like she's stalking Madoka—such as when she appears outside her bedroom in the middle of the night to deliver an ominous message—but she has completely non-perverse reasons for doing so.
Rebellion did not help matters, considering that it becomes amply clear in that movie that Homura is obsessed with Madoka to a very unhealthy degreeto the point of breaking the laws of reality itself with what she herself refers to as The Power of Love to basically undo Madoka's sacrifice.
Even the title character doesn't get away from this. Though the circumstances of the series make it perfectly understandable, Madoka is often the least favored of the cast due to her spending much of the series standing on the sidelines and being indecisive and not knowing what Soul Gems were (never mind that Kyouko didn't know either). Some fans let it go after watching episode 10 and learning that not only was she actually a badass who leapt at the chance to be a magical girl dozens of times, but in the current timeline it's Homura who's keeping her sidelined so she doesn't recklessly lose her life again.
Thanks to the predominance of Fanon for Ranma ½, many of the characters suffer Never Live It Down to some extent.
Akane Tendo used a mallet to hit her Jerk with a Heart of Gold fiancé twice in the anime, and only a few times in the manga... but lots of people in the manga also used mallets, including Ranma (who actually uses it more often than Akane does there), Soun, Genma, and a few oneshot characters. In fanfiction, she's the only one who's ever known to use a mallet when things get violent, despite the fact she canonically prefers her fist (and a shinai, to a lesser extent, in the anime version).
Ranma Saotome claims he Wouldn't Hit a Girl three times at most. Possibly influenced by the prevalence of the Armor-Piercing Slap, fanfic Ranma is infamous for looking down on women's combat abilities, something he never does in either version of the canon, and for refusing to strike back at women even if they're actively trying to kill him.
Please remember, too, that there's a difference between trying to kill someone and actually having a shadow of a phantom of a prayer of succeeding. Ranma doesn't go full out against Akane, Ukyo, or Shampoo because they're no threat to him. That has nothing to do with them being female either; he's just that good. And to a lesser extent Kodachi, although that was more a case of Rumiko Takahashi needing a way for that fight to last longer than 3 panels.
Shampoo once made usage of special mushrooms that made the consumer vulnerable to hypnotic suggestions, and twice tried to take advantage of a piece of love magic that fell into her hands. She didn't even plot the mushroom incident on her own in the manga, where the mushrooms were sent to her restaurant by accident (it was implied to be her idea in the anime, though). Fanfiction portraying her as a villain invariably plays up her as being a kind of "mistress of love potions and mind-controlling poisons". In canon, chemical usage is the specialty of Kodachi Kuno. And even Kodachi sticks with paralysis and sleeping powder.
There was also that incident with the memory erasing shampoo (even if it was really pressure points).
Also, according to fandom "Obstacles are for KILLING!". There were only TWO times when she either seriously said so in front Ranma and/or Akane (her first story, when she grumbles this "excuse" when Ranma begs her not to attack Akane, and during the Phoenix People story, when she actually was under More Than Mind Control and was ordered to kill Ranma) or thought so (when Taro kidnapped Akane, Shampoo quite obviously intended to kill her and lay the blame on Taro, although she never actually voiced the plan, and she fell victim to a cold water trap that Taro set to keep anyone to approach Akane). The others involved more the "I'm an Amazon and you're my love rival, so it can't be helped!" gig than trying to murder Akane bloodily just for shits and giggles or to cruelly and venomously spite Ranma for not choosing her.
Akane stopped calling Ranma "pervert" relatively early on in the manga, and when she used it again after many, many volumes of absence, the obvious Call-Backmade it very funny. To the fandom, it's pretty much her Catchphrase. Though she does frequently accuse him of lecherous intentions, it's rare that she actually says "pervert".
Amongst those who dislike Akane, a commonly listed complaint is that she's a hypocrite with a blatant double-standard — this references her very first argument with Ranma, where she angrily responds to Ranma pointing out that Akane was the one who walked in on him in the bath by asserting that "it's different for girls". In fairness, it's not her only moment as The Unfair Sex, but it's the one everybody seems to remember.
Everybody assumes that Genma Saotome was constantly selling Ranma's hand in marriage for petty reasons, to the point that in the fandom's heyday, it was a standard gag for a new female character to be accused of being (if not actually be) a new fiancee for Ranma. Whilst this has its basis in the Ukyo and Martial Arts Dining storylines, it mostly stems from the anime rendition of the Martial Arts Takeout story, in which the plot focuses on a girl that Genma promised Ranma's hand to in exchange for a bowl of rice, some grilled fish and some pickled vegetables (he was lost and starving at the time), and which ends on yet another "father in law" showing up. In fairness, if Genma has done it at least twice, it's reasonable to assume he's done it even more, because Genma's kind of a douche.
Ryoga shouted "Ranma, prepare to die" whilst attacking Ranma out of nowhere exactly once, in their first confrontation in the series. In fanfiction, this is basically his trademark introduction.
There's one particular episode of Sailor Moon Stars where Setsuna/Sailor Pluto scares the living daylights out of the girls on about three occasions by popping up out of the blue. The girls are eating ice cream when she appears. She pops up holding a popsicle. This episode made her famous in fandom for the Stealth Hi/Bye.
Mamoru, in the anime, broke up with Usagi once, during a storyline in which he was having cryptic nightmares that Usagi would die if he didn't stay away from her. They got back together when Usagi had a nightmare too and realized what was really going on. They basically vow to Screw Destiny and fight off whatever threat comes together. During the entire storyline, Mamoru was shown privately grieving their separation and several times deigning on the Screw Destiny route himself but stopping out of fear for what would happen to Usagi. The eventual source was proven to be a future form of himself trying to test the strength of their relationship because of the powerful threats they would face from the Black Moon. The way some people (especially Seiya/Usagi fans) tell it, Mamoru despised Usagi throughout the entire series, constantly abused her or ignored her, and only got back together with her out of duty to the relationship they had in their past lives. Not even the fact that they hooked up rather fast after The Reveal completely washes it down, as he didn't exactly loathe her beforehand despite all the times he teased her.
In the DiC dub, Rei went from a Tsundere who cares deeply for Usagi despite constantly needling her in the first season to a bullying Commander ContrarianLeader Wannabe. This, plus her past romance with Mamoru/Darien, meant she was ripe for demonization by fans; some fanfics even twisted her into a vengeful harpy who would have Usagi killed just to get back into Mamoru's pants and be leader of the Senshi.
Nephrite was seen taking a drink of whiskey in episode 21 of the original anime, and had a brief, fleeting romance with the 14-year-old Naru. Fandom forever branded him as a drunk and a pedophile.
In the first season finale, the Inner Senshi all died and Usagi had to go on to fight Queen Beryl and then Metalia alone, drawing strength from her friends' spirits to keep her going. The only other season to do anything remotely similar was Stars, but from the way some fans talk about it you'd think every single big battle ended with Usagi whimpering as all her friends tuned into cannon fodder and finally using her power when their ghosts came back to pat her back. This Very Wiki has even accused her of such.
Jadeite's sexism in the 90s anime, especially in his final episode, has led a good chunk of fandom to see all of his incarnations as a raging misogynist.
Sailor Mercury has an unfortunate reputation for being a "weak" Sailor Senshi because of her first season attack, Sabão Spray. Because its purpose was creating a fog out of bubbles, many fans joke about it being useless despite it being Boring, but Practical. It reduced enemy visibility, allowing another Senshi to attack while the enemy was blinded. Despite getting more offensive abilities in later seasons that were on par with her teammates, many fans still view Sailor Mercury as the one with lame powers.
Usagi's Crystal incarnation is forever treated like a pathetic selfish bitch who only wants her True Love and doesn't care about her friends despite plenty of evidence to the contrary.
The Inners are forever accused of "being desperate to find husbands by 15" because of their past life romances with the Shitennou and daring to be sad when the guys were killed. (Granted, the scene wasn't handled well, but still) There's also constant cries of "Faux Action Girl!!" over them being shown to get hurt or flattened during battles instead of curb-stomping every enemy they came across, even though in the end they always managed to pull themselves up and kick some ass anyway.
Shiryu from Saint Seiya was blinded during a fight, and quickly became a Handicapped Badass, before being healed. Then, when fighting a Medusa saint, he blinded himself again, to take advantage of the skills he already had without being turned to stone. But ask the fans, and they'll tell you Shiryu becomes blind every other episode.
School Days is a unique deconstruction of the Harem genre of anime, but its lasting legacy can be summed up with two words: "Nice Boat".note The series finale featured the brutal deaths of two main characters. The day before the final episode aired, a Japanese youth killed her father with an axe. To prevent controversy, many TV channels in Japan replaced the episode with a half hour of peaceful scenery, including images of a boat, set to classical music. Not helping matters is the fact that the last shot of the final episode is of one of the surviving love interests sailing away on a boat with the dismembered head of the protagonist.
In Sekai-ichi Hatsukoi, Hatori gets a LOT of flak for what he did to his love interest (and childhood friend) Chiaki. Basically, he was stressed out from having an unrequited love for twenty years, his childhood friend was dense and his rival was rubbing it in his face that he would get Chiaki first. So what does he do that's so horrendous that that's all what people remember him for? He brutally rapes Chiaki despite him begging him to stop and being physically, mentally psychologically broken during that moment. And then he gets Karma Houdini when the two hook up later. Needless to say, mention the pairing online and the results won't be pretty.
What makes this most noticeable from other yaoi series is that Sekai Ichi Hatsukoi actively tries to avoid using rape to lead to love (making this series more realistic than some others) and so far, the three other pairings have successfully avoided it. This is the only pairing that has rape leading to a relationship, but it falls under Rape as Drama and Stockholm Syndrome. Add to the fact that Chiaki doesn't handle the situation realistically telling Hatori not to leave him instead of distancing himself like a normal person would and also not pitying Hatori during the rape scene also does not help Hatori or Chiaki's case.
Chiaki himself has a Never Live It Down moment from the above but also because of his inability to understand love. Apparently, there is a limit to how stupid you can be when it comes to romance. It's been established that Chiaki while not the sharpest tool in the shed is rather observant of certain things (like knowing Hatori's Berserk Button (since Hatori is a hard person to read) but pushing it anyway as well as knowing what his female audience wants and doesn't want when it comes to his manga along with wanting what's best for his friends and the people around him, he will always be labeled as the stupidest, most insensitive character in the series thanks to his oblivious nature and this attitude is what leads to his best friend Yanase's breakdown.
Episode 10, 15 and 16 doesn't help his cause. Episode 10, Yanase confesses to Chiaki when he's drunk. Chiaki responds by leaving him at the hot springs to run to Hatori. Episode 15, he acts like it's Yanase's fault that the previous incident happened and hits multiple Berserk Buttons in the episode. He denies that Yanase confessed to him in his head and then tells Yanase that he should hook up with one of the female assistants, effectively setting him off. End of the episode has Chiaki get Yanase's hopes up by implying that he'll think about having a relationship with him. Episode 16...Chiaki flips out at Hatori because he saw him with his ex girlfriend and goes to Yanase's place knowing full well that his best friend is in love with him and setting his expectations high. Then the rejection scene comes that leads to Yanase breaking down crying asking why he chose Hatori over him, and Chiaki can't come up with a response. Finally, Chiaki tells him that he'll see him at work tomorrow implying that he just ignored the confession a third time.
Shima Shima Tora no Shimajirō will forever be known in the west as the anime with the weird toilet training episodes (or worse, Pants-Man), all because the first video of the anime ever uploaded to the Internet and promptly discovered by westerners was that one toilet training episode.
Fans of Shugo Chara! think that since Ikuto is very flirtatious with Amu, he is a playboy. He isn't, because Utau once even said that Amu was the only girl he ever loved.
Slam Dunk has Kogure and his episode-long flashback three-point shot, to the point where every sports anime is expected to have those.
Many fans of Sonic X will never forgive Chris Thorndyke for infamously taking Amy Rose's part with Shadow, despite other characters doing the exact same thing to her in other adaptions of the Sonic franchise.
The eponymous protagonist of Space Dandy only commented on how much he liked a woman's arse rather than her boobs in the first episode. Yet, ever since then, and even after saying he doesn't think like that anymore in the following episode, he's known memetically by the fandom as an ass lover.
This isn't quite true. He mentions liking booty multiple times over multiple episodes, including during the Chameleonian episode where he claims to be a slave to "the booty", and the High School episode where he sings a song in praise of Freckles' ass as well. He does however talk much more about "Boobies" throughout the series.
For Yu-Gi-Oh!, people who complain about shows they don't watch have always made fun of Yu-Gi-Oh! characters for having strange hair. In the original show however, only Yugi had exceptionally strange hair. The only other people who came close (like Honda and Otogi) were really no different than any traditional cartoon caricatures. Of course the later series (not made by the original creator) ran with this, and led to another lead character with strange hair in 5Ds.
Anzu/Tea is often bashed for her speeches about friendship. However, the friendship between the four protagonists is the central theme of the show aside from Duel Monsters, which was a Plot Tumor; friendship was the main original point. There's also the fact that A—this is mostly a dub-only trait of hers, she's much less preachy in the Japanese version, and B—as it is the central theme of the show, the other four give speeches about The Power of Friendship just as much as she does, especially Yami Yugi. The main reason she gets hit with this particular stick is that she's mostly uninvolved with the plot, which means that while most characters do talk about friendship, Anzu has considerably fewer moments besides, with only a small handful of duels to her name.
Mai has her skills frequently called into question because most of her on-screen duels ended as losses. Fair enough on its own, except for three things: she never went beyond recurring character status, effectively reducing the number of on-screen duels she had to begin with, the most significant duels she had were up against one of the key characters, namely either the protagonist or the arc Big Bad, and even so, she put up a strong fight each and every time and came within victory's reach.
Jack and Aki, due to losing to Andre back to back in the WRGP. Regardless of how much Jack improved himself afterward, that massive upset pretty much forever placed a massive gap between him and Yusei in the eyes of the fandom. Meanwhile, Aki, despite going out on her own terms by getting Stardust Dragon out on the field before Yuseis turn, was largely left Out of Focus throughout the season, and therefore only received any kind of credibility in the near start of the season and the last arc.
Jean, the leader of Team Unicorn, is pretty much exclusively associated with foregoing a strategy which would have won him the duel (namely, Yusei's Deck had been emptied, so just ending his turn would have won the match) in favor of a more aggressive strategy that cost him the game. His team may have come only one move away from handing the good guys a major early loss, and he had played fairly well beforehand, but him making such a boneheaded move handily cancelled out all the menace generated by his compatriots in the eyes of the fandom, especially after his comrade Andre made a much stronger showing.
Yusei, the eventual victor of the Duel, got hit by pretty much exactly the opposite effect: after defeating the whittled-down Andre, beating Breo in succession, and winning to Jean due to Jean making the aforementioned misplay, he became forever remembered among fans as the king of Plot Armor who outclasses everyone and makes all his friends useless by comparison. Yusei did struggle a lot more early on, and had an implied loss or two beforehand, including major setbacks outside of Duels, but from that point onward, him being an Invincible Hero became by far the most common talking point about him.
In Yu-Gi-Oh! ZEXAL, Yuma's Dueling skills. He suffers a handful of losses early on, but acquits himself fairly well thereafter; after ZEXAL II kicks in, he doesn't lose even once. Still, the fact that most protagonists in the franchise fall into Invincible Hero, along with Astral coaching him early on, means that any losses got remembered a lot harder by the fanbase—particularly his first rematch with Shark.
If Zoids fanfiction were to be believed, one would think Bit and Leena were constantly stealing each other's snacks, but it's only happened maybe once or twice on the actual show.
Hell, people have never lived it down for dubs in general! As subbing purists equate even the act of dubbing with Macekre as a result of these, as if this applied to all dubs even the ones for adults.
For many Western viewers, The Rising of the Shield Hero might as well be called The Rising of theFalse Rape Accusation. Doesn't help that many of those viewers didn't watch past the first episode, so they don't know (or care) that the false accuser has done far worse in the past and future, and gets her comuppance for all of it, eventually. Or that This was part of a conspiracy against the very position of Shield Hero. The timing of Shield Hero's Western premire probably didn't help this: The "#MeToo" movement (and the pushback against it) was still in high gear and the similar controversy over Goblin Slayer's first episode hadn't quite cooled off yet.
