* Choji Akimichi from ''{{Naruto}}'' is constantly prodded into battle by his allies and enemies who call him fat.
-->'''Choji:''' ''(after one of the Sound Genin calls him "fatso")'' "I'M NOT FAT! IIIII AAAAAAM BIIIIIG BOOOOOOONEEEEEEEED!"
** One of the Sound Four, Jirobo, hits ''three'' of Choji's berserk buttons in a single fight--calling him fat and useless, [[LostFoodGrievance eating his last potato chip]] and insulting Shikamaru. In response, Choji takes [[DeadlyUpgrade the third and most powerful of his special food pills]], and it [[spoiler:makes him skinny, gives him magical glowing butterfly wings, and enough raw power to kill Jirobo(in his own Final Form) in one strike.]]
* This exchange from TheMovie is pretty self-explanatory:
--->'''Naruto:''' Man, I don't know where you got your taste in men, Sakura, but it stinks.\\
'''Sakura:''' ''(furiously)'' WHAT DID YOU SAY?!\\
'''Naruto:''' ''(with BlankWhiteEyes and a small voice)'' I'm sorry, what was the question?
** On a more serious note, even mentioning Orochimaru in a respectful fashion in front of Naruto is a good way to activate Naruto's SuperpoweredEvilSide.
** After the timeskip, Naruto and Sakura are both angered by anyone who badmouths Sasuke, or suggests that he is too far gone for them to bring back.
* Lee gets quite angry whenever anyone speaks ill of his mentor Might Guy.
* In ''Shippuuden'', a surefire way to push Kankuro's Berserk Button is to [[BigBrotherInstinct badmouth Gaara in front of him]].
* Never! '''EVER'''! Call Tsunade an [[ObaSan old hag/grandma]]! '''EVER!'''
** Except if you're Naruto, who uses it more as an affectionate nickname.
* [[ChristmasCake The Fifth Mizukage]] does NOT like anyone implying that she's in danger of ending up an old maid. [[TwistingTheWords Even if they're not]].
* Those examples are NOTHING compared to Naruto's biggest berserk button; killing or appearing to kill his friends ( Hinata in that exemple. ). When Pain pushed that button in his legendary MoralEventHorizon in chapter 437, it triggered an UnstoppableRage that would make the fury of the Incredible Hulk seem like a child's tantrum.
** Also accounting for foreshadowing, this specific {{Berserk Button}} is what pushed Naruto through his ''first'' {{Unstoppable Rage}} when Haku nearly killed Sasuke during the Wave Country arc.
*** Speaking of Naruto, you should ''never'' insult the title of Hokage in front of him. He won't care if you're one of the legendary sannin. He won't care if you're a woman. [[PunctuatedForEmphasis He...will...]][-[[PunctuatedForEmphasis KICK]]-][[PunctuatedForEmphasis ...]][-[[PunctuatedForEmphasis YOUR]]-][[PunctuatedForEmphasis ...]]'''[-[[PunctuatedForEmphasis ASS]]-]'''!
*** One filler arc pre-TimeSkip gives Naruto another BerserkButton. An imposter is going around Konoha, ruining Naruto's reputation (and his good credit at the local restaurants). Worn out from trying to clear his name, Naruto starts to head home...then has a major OhCrap moment and rushes all the way back there to find that [[spoiler:the imposter ate his entire supply of beef ramen that he was stockpiling]]. Cue SuperpoweredEvilSide breaking out.
*** Don't insult his dad in front of him, too. Not even a NighInvulnerable PhysicalGod can get away with it scot-free.
* Initially, Sasuke's berserk button was simply mentioning his brother, now it's mentioning his brother in a disrespectful way.
** Or if you mention his clan...or have a Sharingan "That you don't deserve".
* Shikamaru may be the hardest guy to rile up in the entire series. You might see him irritated, but it's a rare thing to catch him genuinely angry for long. The first guy to do it gets hunted down, [[ImmortalityImmorality blown to pieces]], [[FateWorseThanDeath and buried alive]]. Moral of the story: killing people Shikamaru cares about is a bad idea.
* Don't mess with Gamabunta's sons or underlings, it's not a good idea, even if you're a tailed beast.
* Very few things seem to bother Tobi (being immortal and all) but he gets pretty ticked off if somebody betrays Akatsuki. Of course he has quite the FreudianExcuse.
** Interestingly enough, this might stem from the fact he is [[spoiler: Obito]], who highly regarded friendship & teamwork.
** [[spoiler:Also the fact that Kakashi's "betrayal" (ie. killing Rin) was his StartOfDarkness.]]
* Kakashi REALLY hates Orochimaru and Kabuto's Edo Tensei (Summoning: Impure World Resurrection) technique, which they use to revive dead shinobi and force them to fight. In fact having to fight an Edo zombie is the first thing in the manga that visibly made him rage. In fact he really seems to hate Kabuto in general.
** He also values his comrades, and dislikes people betraying their own. Notably, back during Land of Waves mission in Part I, Zabuza's repeatedly kicking Naruto (who is also [[spoiler:Kakashi's sensei's son, mind]]) and belittling his students pushed him into quite the {{Tranquil Fury}} - once he was freed from Zabuza's Water Prison, the DeathGlare he gave the Missing-Nin was quite impressive. Then, he handed Zabuza his rear end on a platter.
** Another one, but anime only. Don't bring up Rin's death (unless you're Obito). If you do, then he will have no qualms doing exactly the same thing he did to Rin on you.
* Aside from being a StepfordSmiler, [[TheStoic Sai]] doesn't really seem to get fazed by much of anything, whether comical or serious. However, all that changes when [[spoiler:his resurrected brother's body gets blown up by [[AxCrazy Deidara]], who boasts that he can do the same thing as many times more as he likes]]. [[http://img833.imageshack.us/img833/7262/naruto1536625.jpg This is Sai's response.]]
* Hinata doesn't like it when Naruto is in danger. She'll stare you in the eye and try to attack you even if you did just destroy the village.
* Neji had it serious whenever somebody managed to turn his own words about [[YouCantFightFate fighting your own destiny]] against him. Hinata almost got killed for it. Naruto, however, managed to snap him out of it for good.
* Implying that those with a bijuu sealed in them is NotEvenHuman or the use of the term [[NWordPrivileges jinchuuriki]] by anyone who either a jinchuuriki or good friends with one is a major one for Naruto.
* It doesn't take much for Deidara to flip a shit but if you call his art inferior (or a cheap rip-off)...run.
* Don't ever claim that names don't matter to Kabuto.
* The Nine-Tailed Fox, Kurama, really, really hates [[spoiler:Madara]]. His mere presence was enough for Kurama to instantly offer an EnemyMine team-up with Naruto.
** It was understated at the time, but [[spoiler: Kurama ''really did not like'' Pain's view of the world.]] It irritated to much that he inadvertantly [[spoiler: synchronized his own chakra to match Naruto's and the natural chakra Naruto had gathered]] just to have a part in the fight. [[spoiler: doubles as ExoticEyeDesigns, because his fox eyes overlapped with Naruto's frog eyes to give him some kind of freaky orange cross eyes.]]
* Do NOT mention the 1st Hokage around [[spoiler: Madara]].
** One other BerserkButton for him: [[spoiler: Don't stand behind him when he pees, it '''irritates''' the hell out of him. Something Hashirama was fond of doing, just to get a rise out of him. No wonder he hates the man to this day.]]
* [[spoiler:'''[[RoaringRampageOfRevenge Killing Rin in Obito's line of sight.]]''' Don't do it. It doesn't matter if you are a squad of Kirigakure-nin.]]
* Don't call Yagura a kid. He may look like one, but he's actually an [[OlderThanTheyLook adult]] [[spoiler: and the Fourth Mizukage as well]].
* Threatening Konoha in front of [[spoiler: Tobirama aka the Second Hokage]] is a ''bad'' move. It made [[spoiler: Orochimaru, Sasuke and Suigetsu]] freak out by his DeathGlare alone. You better hope that [[spoiler: Hashirama/First Hokage]] is there to stop him.
