These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Here be spoilers. Any thing that has not been aired on the free versionnote one week after the paid version of Crunchyroll should be spoiler-tagged.
Artistic License - Biology: Transplanting organs is a snap, don't worry about them getting rejected or dying from an infection. On the other hand, averted on the matter of DNA — playing with it has killed plenty.
Sasuke's egregious Great Snake Escape. He summoned a giant snake, hypnotized it, jumped in its mouth and teleported it and himself out of harm's way all to avoid a massive 10-kilometer-radius explosion. All of that was done after said explosion had already gone off a few feet away from him, and in spite of both techniques consuming massive amounts of chakra.
Some fans see Itachi 's true reasons for killing the entire Uchiha clan in this light.
Hanzô giving Mifune the antidote to his poison at the conclusion of their battle, because from their initially diametric philosophies they seemed to reach some sort of mutual understanding during the course of the battle by a process nobody was able to follow.
In chapter 562, it's revealed that three minor characters know the Hiraishin no Jutsu, a secret technique of the Fourth Hokage that he never taught to anyone else, even his own students or teacher.
Itachi Uchiha having Izanami just so he could defeat Kabuto with it.
Madara apparently being able to Edo Tensei summon himself to counteract Kabuto releasing the jutsu.
Episode 101 of the original series. The village idiots conspire to exact revenge upon Kakashi by means of hiccuping, laughing and crying powder.
Complete Monster: Naruto is an idealistic series with most villains achieving redemption or having redeeming qualities. That said, two of them outstrip others in atrocity and have nothing redeeming whatsoever to them.
Orochimaru was the series' first monster, and one of its worst. Formerly one of the three Sannin, and a hero of the village, Orochimaru was driven out when it was revealed that he was a Serial Killer and Mad Scientist, who had performed sick experiments on captured villagers, genetically altering infants in order to create super soldiers, and murdering others in an effort to unlock the secrets of immortality. He joined up with the Akatsuki, but was expelled after he tried to body jack Itachi Uchiha, and struck out on his own, recruiting lost children into his Hidden Sound Village with promises of power. He infiltrates the Chunin exams, corrupts Sasuke with the curse mark, and then triggers a war between the Sand and Leaf Villages. During his battle with his former mentor, The Third Hokage, Orochimaru sacrifices three of his men in order to summon the First, Second, and Fourthnote this one fails to fight against the third; resulting in the Third's death. He later does his best to kill his former friends Jiraiya and Tsunade, completes Sasuke's turn to the dark side, and is defeated while trying to steal his body. Having long ago shed any good qualities he once had, Orochimaru shows how low even those with once good intentions can fall, having reached the point where he does not even remember them anymore.
Hidan, unlike the rest of the Akatsuki, has no real Freudian Excuse. An Axe CrazyPsychopathic Manchild and member of a Religion of Evil, Hidan worships violence and death, and sees mercy (or indeed, anything other than full-scale slaughter) as a sin. He and his partner, Kakuzu, corner and capture the Two-Tails jinchuuriki, Yugito Ni, delivering her to Pain for draining and, eventually, death. The two of them subsequently slaughtered a temple's worth of monks in order to collect the bounty on the head monk, Chiriku. During the battle at the bounty station, Hidan engaged Asuma Sarutobi in combat, and used a religious ritual to bind their souls together, then began mutilating himself in order to torture Asuma, ultimately leading to the Leaf Ninja's painful death. When Asuma's student Shikamaru confronted Hidan, Hidan mocked his mentor's memory, and attempted to inflict the same fate on Shikamaru.
Fanon: The tongue-in-cheek sentiment that Sasuke is "Emo".
Faux Symbolism: Danzo's conversation with Itachi in chapter 590. He gives Itachi the choice between siding with the Uchihas, represented by a statue of the Buddha, and siding with the Leaf, represented by a statue of a three faced demon that looks very sinister.
Foe Yay: Gaara was a bit too obsessed with Sasuke before their fight at the Chuunin exam, basically stalking him while he was training, and calling him his "prey". Madara taking the trouble to come and see Naruto in the latter's hotel room just to chat can also be seen this way. Mind you, it seems he watched Naruto sleeping for a while, and he didn't even try to capture him!
Franchise Original Sin: Even in early episodes you could already see that Sasuke was going to be really important and tips about how the Uchiha clan's Myth Arc is key were dropped. Then Sasuke became really important, and the Uchiha clan's Myth Arc swallowed the plot.
Growing the Beard: Any moment in part 1 that serves the methodical advancement from crass jokes/filler to epic sacrifices can qualify, but the introduction of Orochimaru and his ambitious plot are probably the turning point.
Harsher in Hindsight: The bloodline purges in Mist Village were already bad enough when we were first introduced to them by Haku, whose family was torn apart by them, but later we learn that they were orchestrated by Tobi, manipulating the 4th Mizukage, who had a very big grudge against the Hidden Mist since they were responsible for Rin's death. Suddenly, the genocide and civil war take on a whole other layer of meaning as a senseless and cruel act of Disproportionate Retribution, and then they become even more cruel when we learn that Madara orchestrated the Hidden Mist's role in Rin's death, all in order to get Obito under his control.
Jumping the Shark: It's hard to tell amidst all the noise of fans crying how the series has been ruined if this happened at all, or when. Judging by most of the complaints, though, the most prominent candidates are:
Part II's second arc, dubbed the "Penis Arc" in honor of Sai's incredulously tactless comments, which stretched on without purpose due to the Anime team trying to avoid more fillers at all costs (see Arc Fatigue above).
Butt Monkey Tobi introducing himself as a very much alive Madara Uchiha and going on to become the Big Bad.
Orochimaru probably crossed it in his fight with the Third Hokage for the viewers. In-universe, that's peanuts compared to the extremely perverse things he had been up to long before that.
Toyed with regarding one particular character who seems to constantly teeter on the edge of it. He'll successfully commit his final, irreversible act of abhorrent villainy any second... aaaannny second now... Some argue that it's the thought that counts, and he has already crossed it.
One aspiring Big Bad held a newborn baby under the threat of death at the ripe old age of one minute. That's not very nice.
Kabuto has the power to resurrect dead ninja. Using that power to zombify the dead Akatsuki makes sense, and they're all villains anyway. It gets worse when he starts resurrecting other fallen ninja, including Zabuza and Haku. Then he has the gall to resurrect the good guys like Asuma, Chiyo, Neji's dad, and the Jinchuriki. All of these ninja gave their lives defending their family and friends, and now they're brought back from the dead as zombies, fully aware of their actions but unable to do anything, for the purpose of killing the people they died to protect.
Older Than They Think: Jiraiya, Tsunade and Orochimaru were characters in Japanese mythology long before they showed up in this manga. They show up in the story Jiraiya Gōketsu Monogatari (literally "The Tale of the Gallant Jiraiya"), a Japanese folktale. In it, Jiraiya is a ninja who has the ability to transform into a giant toad. He falls in love with and later marries Tsunade, a beautiful young princess (in contrast to the manga, where she is Older Than She Looks) who is a master of snail magic, and battles his arch-enemy, Orochimaru, a master of snake magic who used to be his follower.
Many elements of this series are actually drawn from old Japanese folklore or other fiction. Some of these include: Bunshin, Kagebunshin (including the distinction between the two), using these kagebunshin in a combo, Windmill-Shuriken, Kusanagi, XYZ-Release-techniques (XYZ-ton in Japanese), ninja called Sasuke, Sarutobi, the Element-Kage as ninja leaders, ninjas being able pin shadows to the ground or otherwise manipulate their or other shadows, Ninja Log, etc.
Itach Uchiha, the man who murdered his entire clan, joined the evil organization the Akatsuki, and Mind Raped his little brother twice turns out to be a loving brother and under orders from his village the entire time.
The entire plot involving Kaguya, as it was not even hinted at until late in the World War Arc and less than fifty chapters after she was first mentioned she was made into the series' true Big Bad with Black Zetsu as her Dragon who set all of ninja history in motion solely for her resurrection to occur so she could take over the world.
Strawman Has a Point: Danzou did have a point. Konoha was in bad shape. Having a top-class missing-nin running around planning to further run it to the ground was not a good idea (the irony of Danzou's brand of political solutions in the past being partially to blame for causing this mess in the first place notwithstanding).
Gaara's getting a new level of Woobiedom piled on him as of Chapter 547.
Woolseyism: The Viz translation of "Sexy Jutsu" has it translated as "Ninja Centerfold". However most people like "Sexy Jutsu" Better as it's something more people would get without realizing what "Centerfold" is a reference to.
Writer Cop Out: A common accusation hurled at the ending of the Pain arc, which basically undid nearly every shattering twist of plot that had happened during this huge Wham Arc, including several major character deaths.
Naruto's western fanbase is divided on Sasuke, while he is more consistently popular in Japan. The degree to which this is true varies throughout western fandom (very high in America; slightly more moderate in Latino America and Europe).
Sakura is one of the most hated characters in American fandom alongside Sasuke. In Japan, not so much.
Awesome Art: The quality of the animation varies wildly over the series, but Hirofumi Suzuki's team has been nicknamed "Team God" for a reason. In their first episode, Shippuuden 82, they made playing Shogi more dramatic — and beautiful◊ — than any action scene.
Critical Backlash / Hype Aversion / Hype Backlash: This is probably the most popular ninja-based anything ever and also one of the most looked-down upon in terms of how much of a "generic shonen manga" it is, and the backlash from both directions is proportionate.
Sasuke Uchiha. Many girls in the series had a crush on him or expressed interest, probably some pre-emptive Truth in Television. There are even fans who think of him as more of a Chew Toy than a Jerk Ass, and then there are fans who think he is just as justified in his actions as Naruto is.
Itachi Uchiha since day one, even before The Reveal.
Fridge Logic: With all the wheels within wheels of agendas, over-the-top ninjutsu, Schizo Tech and outrageous twists of plot, if you want to enjoy the show it might be a good idea to nevereverquestion anything that happens. Every once in a while you'll be surprised with a nice Lampshade Hanging by way of Retcon (Why is a supposedly stealthy ninja running around wearing orange? Ah, there's a story behind that. No, seriously.)
Germans Love David Hasselhoff: While the anime is moderately popular in Japan, it's even bigger in America and Europe (and the manga is comparatively more popular, though as with all manga sales they are much lower in foreign markets).
Internet Backdraft: Don't bring up any of the following issues on a Naruto forum. Just don't.
Who's more powerful- Itachi or Jiraiya? When Itachi said he and Kisame could have fought Jiraiya to a draw, was he telling the truth of bluffing to convince Kisame to back out of the fight? What about the fourth hokage in his prime? Where does he fit in all of this? (To further exacerbate things, the databooks have them tied...)
Geez, are the girls in the manga getting the short end of the stick or what? Are we ever going to get a female character who 1. actually has impressive abilities and can win important fights here and now, 2. has more than a tangential bearing on any important plot at all and 3. is alive?
And, last but definitely not least, who should/will Naruto end up with- Sakura or Hinata? (see below, in Ship-to-Ship Combat).
Like You Would Really Do It: Averted; fans seemed resigned to the idea that Choji, Neji, Kiba, Shikamaru, Kakashi and Hinata were going to die, each in turn, despite them being relatively important and well-loved characters.
Madonna-Whore Complex: Extremely present in the fandom when comparing Sakura to Karin. Take a wild guess who is almost always presented as "The Virgin" and who is almost always called "The Whore". Which leads to-
Hinata often being the sweet and pure virgin when compared to Sakura. And all the time when compared to Karin.
Memetic Badass: Many. Aoba, Iruka, Kisame and the Raikage come to mind.
Memetic Molester: Orochimaru, for his tendency to lust over the bodies of teenage boys. Also the 5th Mizukage, for her tendency to cuddle her teenage bodyguard and the rather interesting comments she makes about Gaara and Sasuke.
Possession Sue: Due to the belief that main characters should be awesome, the fans love doing this to Naruto. Then again, due to the belief that their favorite character should be awesome, the fans love doing this to their favorite characters, which pretty much covers everyone.
Was the aftermath of Sakura making her confession to Naruto the end of the story for them? When Word of God says she "used his feelings for her" what exactly does it mean? What does she feel for him romantically, if anything? When Yamato said that despite how Sakura treats Naruto he can see that "in reality, she..." did he mean it that way? Given everything that happened with Sasuke, does Sakura still loving him have any meaning at all for the purpose of this exercise? Was the confession a Take That to the whole idea of Naruto and Sakura together?
What about Naruto's mom's comment that Naruto should find someone "like her" and not someone "weird", when she is conspicuously similar to Sakura and Naruto used the word "weird" to describe Hinata once? It can't possibly be taken seriously In-Universe, but if you look at it as a message from beyond the fourth wall doesn't it spell out plainly how things are going to turn out? Or is this whole thing a coincidence or an instance of, well, for lack of a better word, trolling?
The Scrappy: Sakura has had varying shades of this throughout the series. Out of Team 7 she's had by far the least characterization drive plotted into her (Naruto wants to become Hokage; Sasuke wants to avenge his clan; Sakura wants... What?). Though she has her moments and a solid fanbase (mainly thanks to her immediately-post-time-skip bout of Character Development), her subsequent reChickification has not been very well-received by her fans, let alone by her non-fans.
Squick: In Chapter 513, finding out that armadillo's gender was not necessary. Kishimoto evidently didn't agree, so he treated us to another panel full of it in the next chapter. Yes, we love biology.
They Wasted a Perfectly Good Character: Many Akatsuki fans feel this way about those who were killed off, at least before those who were resurrected by Kabuto's Edo Tensei spell returned. Notable examples include Hidan and Kakuzu.
Neji's father had to die because of a diplomatic incident with the Hidden Cloud Village. At the time they were Hufflepuff House and we weren't expecting this to be anything more than background for Neji's grudge; but later the Hidden Cloud Village actually becomes prominent in the plot and even forms an alliance with the Hidden Leaf, with Neji working in the same division as a Cloud-nin. We'd expect to get a resolution on the inevitable hard feelings, but it doesn't even get an obligatory "we're at war here, let's let old grudges go" exchange. On the other hand, Neji has already made his peace with what happened, and from an In-Universe point of view it would be ridiculous of him to start rambling about old grudges and people who've been dead for over ten years in the midst of a world war when the people he's rambling to are his allies.
Danzo. So many questions surround him: Why he was after the Kyuubi, how he got the sharingans, what role he exactly played in the Uchiha massacre, the extent of his involvement with Madara and Orochimaru, and not least how his ideology was the opposite of Naruto's— all this could've made for an interesting plot. Instead he is sacrificed to hype up Sasuke's new powers before any of this gets resolved.
If it weren't for the fact that names ending in -maru indicate that they're male, Gaara's uncle Yashamaru would have most people fooled as well. To the point that in some translated versions of the manga, the producers mistook him for a woman.
Deidara deserves a mention too. Seriously, he looks like Ino's evil older sister.
Sai was mistaken for a girl by some fans at his very beginnings. Admittedly, his midriff T-shirt isn't helping his manliness.
What an Idiot: Some fans feel this way about the seal Kakashi used to try and seal Sasuke's Curse Mark way back during the chunin exams. Yes, give the kid whose sole motivation is power the seal based on willpower: aka he can only suppress the Curse Mark (which grants tremendous power) if he wants to suppress it aka denies himself that power that seems right there for grabs. Yes, that will totally work. It's like telling a kid who loves candy that there's some Reese's on a shelf, but that they shouldn't want to go get that step stool in the closet to get them.
What Measure Is a Non-Badass?: Aside from a small pool of elites, a lot of sympathetic characters (especially girls) constantly get the short end of the stick in their fights and appear to be physically incapable of accomplishing anything that matters. This generates resentment from fans who every once in a long while find themselves subjected to the hopeless, pointless, doomed antics of these characters failing at life until the Big Damn Heroes show up to save the day. "Character X is too weak/useless to deserve screentime" is a common sentiment in forums.
Ass Pull: Some fans view the true reasons behind his massacre of the entire Uchiha clan in this light.
Base Breaker: Itachi was insanely popular at the start of the manga, and still is in many circles, but he's also become a much more divisive character as his true nature's been revealed. Fans are now divided over whether Itachi is a cool, stoic Bad Ass with an interesting character arc or an insufferably preachy and insanely overpowered character that exists purely to make everyone else look bad in comparison. A huge part of reaction to Itachi is whether people view his character as a Deconstruction of God-Mode Sue, where his overwhelming power and near-invincibilty in battle highlights his many shortcomings as a human being, or God-Mode Sue played depressingly straight and absorbing a disproportionate amount of praise from others despite the many terrible things he did, only admitting his failings to look humbler and even more praiseworthy.
Draco in Leather Pants: Some fans tried to rationalize his participation in the Uchiha massacre, saying that he was under orders. To a degree, they were right. It still does NOT justify the repulsive extremes that the fandom will reach to excuse his Moral Event Horizon crossings, and there's also the fandom's extremely creepy refusal to aknowledge that his actions are a big part of the reason why Sasuke is now fucked up to the degree that he is.
Dying Moment of Awesome He was captured and he was going to fail his mission, because the information he collected was intercepted and he was going to be interrogated which is impossible to resist. What did he do? He used the last of his chakra to summon sharks that ate him alive in a matter of seconds. His whole body. Oh, and that seal on the information had a trap that paralyzed everyone around it for long enough that the jutsu could bring it to the Akatsuki. What a way to go down.
Nightmare Fuel: Late in the series, his BFS. His sword is alive and it eats chakra. It feeds him the chakra it eats and heals his wounds. On top of that, it has a mouth as large and sinister as a shark that it can hide in its spikes. When you actually see the uncovered, it is a huge blade made up of dozens of long pointed ends that are meant to tear flesh like a shark's jaw.
From Bad to Worse: Kisame fuses with his BFS and turns into a two-legged shark hybrid.
Squick: Suggesting they cut Naruto's legs off so it would be harder for him to get away, and almost does this to Killer Bee before he grabs the pencil he threw at the start of the fight.
Nightmare Fuel: Everything about him. He is half plant and he is actually two people in one. Besides from the large, green fly catcher like mouth that usually covers his head, his body is divided in half vertically. Half is body is pure black and the other half is pure white (yin/yang). Which half is a person with his own mind and they have different personalities to boot. He can "tear" himself in half which causes the personalities to split.. into two half bodies (not many people see a man with half his body missing, but still running around). He records battles from a distance since he can phase shift into any object. The black half is a bad ass assassin and the white half is a shape shifter that can appear as any person. Madari/Tobi clones him and the clones infiltrate the combine shinobi force and they kill a lot of people. Whew. If anyone know how he became what he was it might help or it could just make things a lot worse.
Broken Base: Not Deidara himself, but Sasuke has this effect on almost every Deidara fan after Sasuke lived and not Deidara.
Though some of his fans insist it's more that he was defeated with an Ass Pull than that he was defeated (he was a villain, after all)
Dying Moment of Awesome His motto is "art is an explosion" so he blew himself up in an explosion so big it wiped out miles of forest and it probably could've been seen from miles away. He did it just to try to kill Sasuke.
Ensemble Darkhorse: In one poll he was more popular then the titular character himself (this was his first poll ever and he ranked #3, higher than any Akatsuki member then or since). In the last poll he was still a very high #6. Likely linked to...
Evil Is Cool: Many fanboys will forever love him for the number he did on Sasuke.
Worse is during the 4th War, he realizes that as a zombie he can use his suicide technique over an over, and his reason for not doing it is that he thinks it cheapens the art, not that it's, oh, I don't know, constant suicide?
Younger than They Look: He was 19 when he died, two years younger than Itachi, but because some think he does look 19, others think he looks older. His attitude fits right in with this age, of course...
But it makes some of the Ho Yay moments with Tobi much creepier since Tobi was thought to be Madara Uchiha (aka around 200) and now he's at least been shown to be somewhat old.
Draco in Leather Pants: His human puppet form is quite attractive, but some forget he's killed hundreds, maybe even thousands, of people, and maybe provoked a war by abducting and killing the 3rd Kzekage.
Sasori: Do you know how I add to my collection? First I tear out the organs. Once I've washed it clean, I drain out all of the blood. After I've made sure it won't decay, I fill it with weapons and traps, and add it to the collection. As grandma said, Hiruko is part of my collection. With you and Chiyo, I will have exactly 300 puppets in my collection! This is my art!
Tobi/Madara Uchiha/Obito Uchiha
Can't Un Hear It: Many fans consider Megumi Han's performance as young Obito to be a lot more memorable than that of his original voice actor, Sosuke Komori.
Common Knowledge: He is absolutely not the mastermind of Mist's policy to exterinate bloodline users, largely because no such policy actually existed. While bloodline users were persecuted in the Water country, that was by ordinary people, not the Mist village; the only clan the Mist wiped out was the Kaguya clan, and that was only in self-defence. Nowhere in the manga is it stated that the Mist conspired to annihilate bloodlines or that he had any problem in particular with non-Uchiha bloodlines.
It Was His Sled: Tobi not only isn't the real Madara Uchiha, he's also Obito. Both were huge spoilers when first revealed, but by the time they were animated, both facts had become almost impossible to hide.
Magnificent Bastard: Or at least he gets points for trying. Gets props for infiltrating his own organization pretending to be and convincing many people he was silly, goofy Tobi when he was actually The Man Behind the Man of the organization, seemingly because he can.
Memetic Molester: The infamous SURPRISE BUTTSECKS panel before Sasuke fights Danzo.
Motive Decay: Zig-Zagged. We are led to believe that he initially wanted to protect the Uchiha clan, but eventually grew bitter after his clan ostracized him, and wanted to (and helped to) destroy them along with the rest of Konoha. And now we just do not have an inkling of a clue about who the hell he is in the first place.
Squick: You know those amusing scenes that painted Tobi as a complete goofball? Rewatch those with the knowledge that he's an evil, creepy old man and try not to be a little disturbed.
It's worse when you look at the databooks and realize that person he's being all Ho Yay with, Deidara, is only 19 years old. Dirty Old Man much?
Alternatively, it's Hilarious in Hindsight, because he's apparently just screwing with people for the hell of it.
Wangst: Many consider his reason for turning evil - the death of Rin, his childhood crush - to be poorly executed as a Freudian Excuse.
Base Breaker : Just don't mention the words "Hidan" and "Shikamaru" together on any forum. Hidan and Shikamaru fans will appear and rumble. Remember though, there are plenty of fans who like both. And even some who ship them.
Faux Affably Evil: Easily the most sadistic of all of Akatsuki and devoid of any redeeming qualities, but his arguments with Kakuzu make for some good humor, as do his Large Ham tendencies (which are much more apparent in the anime). Obviously Your Mileage May Vary as to which one you believe him to be.
Draco in Leather Pants : Some of Hidan's fans seem to totally ignore that he's a violent psychopath and hate Shikamaru for killing him. Even though Hidan had previously brutally killed Shikamaru's mentor and was going to return to Konoha to capture Naruto. If Shikamaru didn't take him out, someone else would have.
Moral Event Horizon: He seems to be a nice Affably Evil villain (more so in the anime) who gives out reasonable complaints about his job, ritual and his partner's line of work, a while acting more like a understandable complainer. This goes all out the window once he goesinsane and kills Asuma and later insults his students about how weak he was.
Nightmare Fuel: The Earth Grudge Fear, that relies on tearing the living hearts of his victims. Also the black beast that emerge from his back.
They Wasted a Perfectly Good Character: The patron saint of this trope in Akatsuki. He was one of their most powerful and terrifying members, he had an interesting backstory and a good personality...but he was one of the only villains that didn't get his flashback as he was dying despite having a much less trite backstory than some future villains, and he died offscreen during the Edo Tensei battle of the Ninja War.
No Good Deed Goes Unpunished: This is a man whose only desire in life was a world of peace and compassion, and he struggled to make life better for everyone. Fate's response was to destroy everything he held dear in the meanest possible way, thus causing his Start of Darkness.
Too Dumb to Live: Dances extremely close. He deliberately provoked Naruto as cruelly as he could to "teach him pain", assured that he had the power to defeat even the fully-unleashed Kyuubi. He was wrong. And the only reason he wasn't dead wrong was the 4th Hokage's emergency measure.
Ensemble Dark Horse: One of the more popular female characters with a massive fanbase. Her status as this trope was basically confirmed based on the collective freak out the fanbase had when they thought Pain had killed her, then re-confirmed in a publication 2011 character popularity poll, where she was the most popular female character and the 10th most popular character overall. This is Lampshaded several times in the anime, where a character (usually an annoyed Sakura) comments about Hinata's large popularity despite not being the main heroine. The episode 165 omake flat out states that even the anime producers are Hinata fans.
Never Live It Down: She faints once on-screen in the manga and all of a sudden the fanbase and the anime team are convinced that she can't be near Naruto or hear his name without fainting. Although to be fair, Kiba does confirm that Hinata has fainted around Naruto more than once.
Purity Sue: Fanart sometimes portrays her in this light.
Real Women Never Wear Dresses: Often bashed for being more traditionally feminine and more stacked than the other female ninjas, as well as for her shyness around Naruto. She's an interesting inversion as far as wardrobe goes, though; Hinata typically wears pants (with the exception of two short scenes, one in a flashback to her third birthday), while Sakura and Ino tend to wear skirts.
Too Dumb to Live: Brave though it was, it has to be said that charging in to attack Pain, an opponent far stronger than her - and who she knew she had no chance against - with no support, no backup and no plan, was a really bad idea. Changed in the anime which gives her a better gameplan.
Base Breaker: Never ever mention his and Hidan's name together. You'll be in for a huge flamewar. And never ever ask if his arc as a whole was a Broken Aesop about the theme of revenge. You'll risk seeing a mighty bloodbath among Sasuke fans and Shikamaru fans. Andthird parties.
Launcher of a Thousand Ships: Despite having so called "canon" ships with Temari, Shiho, and Ino, you'd be surprised how much he gets around.
What Were You Thinking?: leaving Choji and Ino, both of whom are primarily support ninja and neither of whom have elemental ninjutsu, to fight Kakuzu. Good thing Kakashi was there too and that Team 7 showed up.
On the other hand, keeping Kakuzu and Hidan together could have been suicidal for Team 10 in general. The duo's combined and synchronized attacks had been shown to force Team 10 and Kakashi onto the complete defensive and would've arguably kept them there if not for Shikamaru's quick thinking. Even if Team 10 had gone back to fighting as they did before, it would probably only have been prolonging the inevitable. Shikamaru leaving behind his teammates in a literal Taking You with Me ploy may have been the only way to deal any sort of damage to the immortals at that point (even if it hadn't been part of his plan all along).
Squick: His bugs live inside him. Even the Big Bad was grossed out by it.
Die for Our Ship: At the beginning of the series, she was hated by Sasu/Saku fans for having a crush on Sasuke and being better endowed than Sakura. Now that Karin has come into the picture, they mostly leave her alone. She's still not very well-liked by Shikamaru/Temari fans though.
Woolseyism: Lee speaks formal, polite Japanese. In the English dub, he does not use contractions at all in an attempt to convey this, and in the Latin-America Spanish one he uses a military speech pattern with an enthusiastic accent.
Harsher in Hindsight: When Naruto first defeated Neji in the chuunin exam, he convinced him that he isn't bound by fate, just as Naruto is able to defeat him even though he is a failure, while Neji is born with a pedigree that makes him strong. Later we learn that Naruto's father was the Fourth Hokage (arguably the most powerful Hokage to live), and his mother came from a clan that was related to the first two Hokages, making his pedigree even better than Neji's, and meaning that if fate existed, it was fated for Neji to be defeated by Naruto. Now, is Neji really free from his fate, or does he only act like he is, not knowing that he is doing exactly what was fated for him?
Too Cool to Live: He could actually kill Pain, the enemy who his entire Village, the Hokage, his animal companions and even his student having perfected his strongest technique and backed up with the power of the strongest Tailed beast at the same time couldn't, if he had knew his secret.
It should be noted that most of her "violent" outbursts are Flanderization of the anime, as with her alcoholism which was actually requested to be toned down by Kishimoto's editor. Her strength, however, remains to be seen given that she hasn't had a fight since getting back into shape after her twenty year hiatus from the ninja lifestyle.
Iron Woobie: As if you didn't feel bad for her when she worked herself up into a coma trying to heal everybody in the Leaf Village...
Even Evil Has Standards: MAY have shades of this. He did defect from Akatsuki for as-of-yet unknown reasons. Tobi hints that he knew more than he let on, and Orochimaru does outright tell Tsunade after a failed attempt on Naruto's life that if the boy lives that to paraphrase: "worse things will occur."
Villain Decay: After facing a Kage, the other two Sannin when he didn't have arms, and fighting Four-Tails to a draw while sick and dying Sasuke unceremoniously kills him. After coming back from being sealed inside Sasuke's body, he's ultimately killed in the course of about ten pages by someone much farther along on the Sorting Algorithm of Evil: Although doing so did contribute to said character's death.
Angst? What Angst?: When Naruto discovers he's the host of a demon that nearly destroyed his village, he's awestruck. The next morning, he just goes about his business as if nothing happened.
Base Breaker: While not as prevalent as fandom's reaction to Sasuke, Naruto's characterization in Shippuden rubbed a lot of fans the wrong way.
Since Naruto is only Stupid Good in regards to Sasuke, this may be less to do with Naruto, and more of a side effect of Sasuke's Base Breaking. Imagine that.
Waaaaaay back when the show started, Naruto was also this in early episodes of the anime series (especially in the dub) due to being a loudmouthed, hyperactive Idiot Hero, causing quite a few potential fans to be turned off immediately.
Iron Woobie: Taken to ridiculous levels in fanfictions, where he is beaten at least ONCE A WEEK most of the times he doesn't know about Kyuubi yet he still forgives them. Not that his assaulters learn anything.
Special mention must go to a particular clone of his during the Shinobi World War arc, which lasted for an impressive eighteen chapters rather than disappearing as soon as it got hit. Some people actually prefer this clone, which people have called "Datclone", and would have liked to see it as the main character instead of the real Naruto.
Stupid Good: When it comes to anything involving Sasuke.
Woolseyism: "Believe It!" was meant to fill in the mouth movements for "Dattebayo" in the dub. Over time, he stops doing this.
Alternate Character Interpretation: One can argue his quest for revenge falls under filial piety rather than self relief. Filial piety is a critical feature of Asian civilizations (including Japan). Hence, the only people he will ever recognize allegiance to are his dead parents and clan. He basically lives for the dead ones. The fact that he totally ignores Itachi's will can also be explained this way, because Itachi was only one among many others. Pretty much confirmed after he kills Danzo, where he rants about how good it feels to clear his clan's name by killing people, and sees it as his mission to do so. May be one of the sources of Values Dissonance between Japanese and Western fandom.
Alternatively, he is on to Tobi and biding his time. Tobi is directly responsible for the demise of the Uchiha Clan, if he is Madara exiled and not part of the family. After waking up, Sasuke had little other choice than to pretend to join or he would have been killed easily. He ignored the genjutsu which he should have seen through cast by Bee to get out of the mission, dumped Karin not fatally wounded on the most skilled medic nin he knows and left Juugo and Suigetsu to their own devices so that Tobi couldn't use any of them as leverage against him. After he has a power upgrade and enough knowledge to beat his opponent he will set out to complete his revenge. In the meantime he's probably hiding out in Itachi's room.
Evilis Cool: As is noted below, many people like him better now that he's gone from an anti-hero to full-fledged villain.
Fashion-Victim Villain: His first outfit at the start of the timeskip has been described by some as making him look like a "fat gay pirate". He's wisely ditched it since then for slightly more dignified costumes.
Foe Yay / Ho Yay: With Naruto, depending on your interpretation. Also with Suigetsu and Juugo.
For those who don't know, "Nii-san" is Japanese for brother. He just stabbed Danzo through the heart with an electric blade, but Danzo had Karin as a hostage, so he hit her also just so he can get Danzo. That statement just shows how easily manipulated Sasuke has been since he believes without a doubt that Tobi is telling the truth. The Fridge Horror comes along if you didn't know what Nii-san meant and then you looked it up.
Well, Danzo confirmed Tobi´s words.
Only that Konoha had its hand in the Uchiha Massacre, not the sob story Tobi cooked up to make the Uchiha look sympathetic.
Hollywood Pudgy: Has been called "fat" by fans, even though he's really got an average (or even athletic) build. (Adopting Orochimaru's sense of style didn't help.)
Iron Woobie: For all the wangst the character is accused of, for the most part Sasuke had keeped quiet about the Massacre and his pain, only stating in short sentences very sporadically to justify his goal. Hell, the reason Sasuke crying after Itachi's death was so powerful was because it was the only instance in the actual Time Line he had ever done so.
Motive Decay: Actually averted, despite his behavior. It's his methods which have decayed. He has always wanted to restore the Uchiha clan's name and his own pride but how he thinks he should do so has gone from killing Itachi —> destroying Konoha —> killing Danzo —> killing every last man, woman and child in Konoha and erase the bad name of the Uchiha clan from history.
Ron the Death Eater: His portrayal in the earlier parts of the manga is subject to this, despite the above leather pantsing. People tended to crank whatever negative traits he had Up to Eleven, like constantly insulting his teammates or thinking that he's better than everyone else. While he was an Arrogant Kung-Fu Guy before the timeskip, he had at least the decency to keep it civil for the most part. In the first part, he's willing to pull a Heroic Sacrifice to protect Naruto and Sakura. Even in the second part he was strongly reluctant to kill without reason. But since chapter 480, he canonically got (much) worse.
Stoic Woobie: Fanon notwithstanding, this was the first characterization of Sasuke, only breaking momentarely after being brutally tortured by Itachi a second time and a small gloating to Naruto in the Valley of the End. This went to eleven after the Time Skip, being almost emotionless. In fact almost anything we knew about him and the clan where by short monologues during his spotlight and some flashbacks.
Values Dissonance: One of the reasons why American Fandom is so divided regarding the character: His sense of justice and Vengeance (to personally kill the Masterminds of the Uchiha Massacre so the spirits can rest, going against the wishes of Itachi and loyalty the Family, the clan above all else) are very rooted in (ancient) Japanese/Chinese morality. Yes, he is barking mad at this point, but is easier to swallow if looked with this mindset instead of a "modern" one.
Die for Our Ship: Many fangirls acknowledge her only as the obstacle for Sasuke and/or Naruto to get together, either with each other other people or even her because how she easily switches between between the two of them.
Iron Woobie: His father committed suicide out of shame. Everyone who was on his first ninja team is dead or hinted at being dead. And his once promising student defected to the side of the sworn enemy of Konoha and has recently passed up any chance of being redeemed. Despite all this, he has spent very little on-screen time angsting.
Ron the Death Eater: He is sometimes accused of playing favorites towards Sasuke. Also, some fanfictions have him hating Naruto for having the Kyuubi sealed in him since Minato sacrificed his life in order to do it.
Memetic Badass: In addition to being revealed to be an enormous Badass in real life, the First Hokage is generally considered capable of curb-stomping anyone in the Narutoverse besides fellow Memetic Badasses the Fourth Hokage, the Raikage, and Zabuza's sword, which cannot be beat.
Broken Pedestal: Sure, everything Tobi said about his part in organizing the Konoha Military Police Force and keeping tabs among the Uchiha might be bullshit, but the fact that he was unable to tame their grudges enough can still speak volumes.
Harsher in Hindsight: By all accounts, the Second Hokage was a just, kind-hearted man of honor and a beloved leader to most of Konoha, but his legacy has contributed greatly to the success of evil in the story and been used to harm the very people he wanted to protect. Edo Tensei, a forbidden jutsu he "conceptualized"? Hijacked by Orochimaru to revive him as a weapon against his own student and indirectly condemning all of the Hokage so far to a Fate Worse than Death, then later "perfected" by Kabuto to unleash a Zombie Apocalypse. His Heroic Sacrifice to save his students at the cost of his own life? Later contributed to Danzo's extremist philosophy, which got a lot of people killed. His formation of the Konoha Police Force, and giving his former enemies the Uchihas command of that force? While debate rages on if this was a pure-intentioned peace offering or an attempt to tie the Uchiha to the new village, there's still the fact that Madara and Danzo both hijacked whatever intentions the 2nd had to serve their own ends with the Uchiha massacre. Some even speculate that the space-time abilities he was said to have might still be in use...by TOBI.
Ron the Death Eater: He was a man with both good qualities and failures, like any man, but Tobi painted him as a villain in his slanted account of the Uchiha massacre, and ever since then, if a Kage is going to get demonized, it's this guy. It does bear pointing out that most of the bad things that are traced back to him happened some time after his own death and were more the result of other people perverting what he left behind for their own use; see Harsher in Hindsight above.
Ensemble Dark Horse: To the extreme; an essentially minor character that has a huge fan following, to the point where he's been in the top 5 of most popularity polls.
Ho Yay: Some fans see this between him and Kakashi although the two barely even interact in the manga. Nonetheless, Kaka/Iru is a popular slash pairing. It probably comes from the fact that they interact and hang out much more in the anime, specially in the many, manyFillers.
Memetic Badass: Despite only managing to get wounded with a kunai and getting hit in the back with a giant shuriken in his only real battle in the manga, against an opponent that Naruto defeats in the first episode/chapter, Iruka has quite a reputation on the Internet. Supplemental material supports this, indicating that the only reason he's not a Jonin is that he prefers to remain an academy teacher, and that he's actually stronger than the Special Jonin Anko. His stats are fairly good all around and better than most of his former students. He's actually too nice to be a field jonin. The Third Hokage calls him out on this in a flashback.
Crowning Moment of Heartwarming: In possibly what seemed to be an emotional and horrifying struggle for Naruto in Chapter 497 since the Invasion of Pain when the Nine-Tailed Demon Fox once again infects him with the hatred he sought to abandon to control that Eldritch Abomination, Kushina appears to reassure her son that the village he protects (and the Nine-Tails sought to destroy) loves him.
Internet Backdraft: One of her final words to the newborn Naruto, asking him to date a girl "like his mother," has already re-erupted the NaruHina vs NaruSaku Ship-to-Ship Combat. Fun. Curiously enough, Naruto specifically thinks of how he has followed (or will follow) all of her advice except this part. Who said "Kishimoto is a Troll" ?
Iron Woobie: His jerkass tendencies can be at least partly explained by watching the Caged Bird Seal tear his family apart, the fact that his daughter was nearly kidnapped, setting in motion a chain of events leading to his brother's death, which he was helpless to prevent, the fact that his nephew nearly killed his daughter, and the strong implication that his wife is dead.
Ron the Death Eater: He is a Jerk Ass, yeah. But still not to the horrifying degrees that fanfic writers use sometimes, like him raping and abusing either Hinata, Hanabi, Neji or even Hizashi For the Evulz.
Die for Our Ship: About the only thing Shikamaru/Temari and Shikamaru/Ino fans can agree on.
Memetic Badass: One of the biggest in the series. He IS kicking the asses of the five Kages, and barely taking them seriously at that.
Ass Pull: Some fans see Rin's involvement in Obito's Face-Heel Turn as including several examples, such as having been made into the Ten-Tails Jinchuriki, then forcing Kakashi to kill her, and later these events, down to the compulsion to commit suicide, being the result of Madara's plan.
Base Breaker: Rin's heroic sacrifice, wherein she jumped in the way of Kakashi's Raikiri attack: the right thing to do in order to save Konoha, or grabbing the Idiot Ball and making a stupid, Senseless Sacrifice? Then there's the issue of her death being the entire reason for Obito's Face-Heel Turn, and the rest is history.
What an Idiot: Rin's decision to jump in the way of Kakashi's attack, so she wouldn't need to worry about unleashing the Sanbi in Konoha, instead of listening to Kakashi. To elaborate, Kakashi refused to kill her when she asked him to do so, and and added that there must be another way.
Die for Our Ship: Fans of Shikamaru with Ino generally dislike her for obvious reasons.
Ensemble Darkhorse: Directly behind Hinata in terms of popularity among fans for the reasons cited below, despite not being featured that much.
Misaimed Fandom: Due to being one of the sole female characters to be actually Badass and successful in practically all the fights she engages in, she is often glorified as a "feminist icon" by her fanbase. See below.
Internet Backdraft: It's been hotly debated on whether his rematch with Sasori and his levels taken in Badass are legitimate,as Sasori was forced to make due with human victims,instead of his regular puppets,and each of Kankuro's appearances has him using another one of Sasori's puppets instead of creating his own. There's also the claim he made that his techniques have surpassed Sasori's,despite the move being shown is simply a slightly different version of his older technique.
To the point where Deviant Art has specific fan-clubs for "bashing" and "protecting" her (though the "protect" club is really just all the pics that don't bash her and the other seems to have a lot more...)
Moe: When she isn't shown dying in childbirth, the panels showing Karura display a woman who looks insanelyMoe. In particular, a panel in 548 shows her and her brother Yashamaru together: she has very wide eyes, is wearing loose-fitting clothes, has the sweetest smile, and seems to be on the petite side if the fact that she's smaller than Yashamaru (who according to the databooks is only about 5'7") is anything to go by.
Ensemble Darkhorse: One of the most popular characters in the series, usually making the top 10 in every opinion poll.
Memetic Badass: "ZABUZA SWORD CANNOT BE BEAT!" Until the Raikage breaks it. And even then, just give it time and blood and it'll be as fresh as just forged.
Hide Your Gays: Nothing is officially confirmed about this but there is... subtext between him and Haku. It is heavily hinted that their relationship might have been more than mentor/student, especially when he requests to die next to Haku and wishes to go to the same place as him in the afterlife. In fact, solely changing Haku's gender would have probably made the pair Canon. Zabuza's parting words really speak for themselves:
Zabuza: "Is it you, Haku? Are you weeping? You were always at my side. The least I can do is to be beside you at the end. I know I cannot be, but I wish I could go to where you have gone...How I wish I could join you there...Haku..."
Moral Event Horizon: Holding Konan hostage to make Nagato kill Yahiko, and once Yahiko commits suicide to prevent Nagato from making the choice, he orders Nagato killed as well. Suffice to say, that didn't go as planned.
Moral Event Horizon: Could be kicking the crap out of Tsunade and nearly killing young Naruto but spamming Kuchiyose:Edo Tensei, implicitly killing many people and violating sanctity of the dead is probably the better pick.
Heck, even TOBI was repulsed by his Edo Tensei spell, and blackmailed into going along due to Kabuto summoning the real Madara Uchiha.
Ass Pull: A Meta example: She is now the fifth named Uzumaki, behind Naruto, Kushina, Mito, and Nagato.
Die for Our Ship: IN. FUCKING. SPADES from SasuSaku fans but also from SasuNaru fans to a lesser degree, who detest her even more than Ino, if only for the fact that she's more..."proactive" in her ways of trying to get in Sasuke's pants. It won't get better, as Sakura has been ordered to heal Karin after Sasuke tried to kill them both which she does. To further infuriate them, Karin not only lives but is seen smiling gently whilst being taken back to Konoha on Kakashi's back.
Designated Girl Fight: Due to this, SasuSaku fans were roaring for a showdown over Sasuke between her and Sakura, which unfortunately for them will never happen now in light of the most recent events.
Irony: A Meta example. Sakura stopped Sasuke from finishing her off and then healed her afterwards. Karin is very grateful and affable afterwards to the point that she willingly goes with them without even trying to put up a fight. Brilliant Take That, Audience!, Kishimoto...
Never Live It Down: The supposed rape that she planned, which was actually the result of a mistranslation. Nonetheless, the allegations are still being brought up years afterwards.
Rescued from the Scrappy Heap: Partially. Used to be one of the most hated characters in the manga but her being so badly hurt by Sasuke and her warning Sakura about Sasuke intending to kill her made her strangely turn into a Jerk Ass Woobie for a good fraction of the fandom. But now stuffed back into the heap because she accepted Sasuke's apology, and in many eyes, too easily.
Slut Shaming: Another meta example. Die for Our Ship aside, the main reason why fans hate her is because she allegedly intended to rape Sasuke, and that, being older, she's more mature in her flirting with Sasuke, much more than Sakura or Ino ever were, who were twelve when they were crushing. Her more open sexual advances, which are taken Up to Eleven in the anime, frequently elicit this trope in fan fora.
Jerkass Woobie: You'd never believe it, but after the downright ridiculous asskicking that it endured, just to have its power taken from it and to be locked away again seems like it would be very depressing for the Fox. This sentiment is starting to be recognized by the fandom..
Even Naruto feels sorry for it, and apologizes for trapping it in its prison again. (not that it deserves any sympathy, but Naruto is an All-Loving Hero after all).
Considering how Ch. 572 depicts not only Kurama, the Fox, but all the Tailed Beasts as embittered entities who considered the Sage of the Six Paths as a father figure, this has grown into Canon.
Add onto that he's spent at least close to a century either mind-raped into slavery by others or imprisoned and treated as a weapon to be used by his jailers, and you can certainly sympathize with him.
Or better yet, strip it of its skin and tail flesh/bone, and you get the eight-tailed state.
Rule 63: To the point (in fanfic) where it is not completely unknown to have people who actually think this is canon. Goes with Draco in Leather Pants.
Base Breaker: She became one immediately after her resurrection. Generally, people who like her disliked Madara as a villain due to her being very direct and serious (where he was prone to bouts of arrogance and show-boating, and seemingly had very strong Plot Armor), or for finally giving the series an undeniably relevant and extremely powerful female character. People who dislike her tend to call her a poorly-written Giant Space Flea from Nowhere who had no place in the Senju vs Uchiha, Ashura vs Indra myth arc that the series had been building up for years.
