History BewareTheNiceOnes / WesternAnimation

* ''WesternAnimation/{{Rugrats}}'': Chas Finster may be a nervous and awkward NiceGuy like his son Chuckie, but he knows when he's had enough. In one episode, Stu and Didi are having a petty feud with Howard and Betty, both factions hating and insulting each other with poor Chas stuck in the middle and unable to make them calm down and reconcile. Near the end, the babies have wandered off (as usual) and when the families do nothing about it but argue some more, Chas is [[RageBreakingPoint absolutely]] ''[[RageBreakingPoint furious]]'' and calls them on their childish behavior, bringing them all to shame and ending the feud. As he delivers his [[TheReasonYouSuckSpeech reason-you-suck speech]] to them all, he even sounds like he's ''[[BerserkerTears crying]]''!

* ''WesternAnimation/HazbinHotel'': Charlotte "Charlie" Morningstar is an incredible polite and affable lady who desires to see the best in people, which is why she's hellbent on the idea of rehabilitating Hell's sinful population. She's also the Princess of Hell and thus one of the most powerful demons around. The only reason why the amount of people who take Charlie seriously can be counted on one hand is because she's NiceGirl in a world full of jerkasses who only respect displays of unadulterated power, and it takes ''a lot'' to push her into even showing a small fraction of her full abilities.

---->'''Nibbler''': Why are you choking me?

** Donatello is no slouch, either. In the episode of the [[WesternAnimation/TeenageMutantNinjaTurtles1987 1987 series]] titled "Night of the Dark Turtle", a shock from an altercation with one of Shredder's machines transforms him into a rage-filled vigilante hell-bent on ending the Shredder. Raphael lampshades this:
*** '''Raphael:''' "I think I liked him better when he was the meek, brainy one."

*** Oh, and did we mention that in the [[WesternAnimation/TeenageMutantNinjaTurtles2012 2012 series]], he's the one who [[spoiler: ultimately ends the Shredder's life to avenge his master?]]

** Leonardo is second only to Michelangelo as the nicest of the Turtles, but as we've seen in ''[[WesternAnimation/BatmanVsTheTeenageMutantNinjaTurtles]]'', harming his brothers is a good way to enrage him.

* "Franchise/TeenageMutantNinjaTurtles": Leonardo, Donatello and Michelangelo all have shades of this, regardless of which version.

* ''WesternAnimation/TheVentureBrothers'':

* ''Franchise/DonaldDuck'': In ''Donald's Better Self'', donald's shoulder angel may be resistant to fighting at first, but as his shoulder devil learns the hard way, even he has his limits.

* ''WesternAnimation/TheAdventuresOfTintin1991'''s Professor Calculus is normally a soft-spoken, mildly eccentric, rather charming old man, who, by virtue of his poor hearing and generally good demeanor, does not notice most of the jokes at his expense, and doesn't care about those he does hear. But then in "[[Recap/TintinDestinationMoon Destination Moon]]" Captain Haddock mocked his ambitions for space travel and accused him of "acting the goat"...

** Gi is usually the TeamMom and peacemaker who tries to [[RousseauWasRight see the good in all humans]]. She also tried to drown someone when she found out he shot her good friend, and it's hinted that when they went undercover to find guns she was going to shoot him. You wouldn't like her when she's angry.

** The title character is typically extremely tolerant and obnoxiously optimistic. However, in one episode Squidward resigns from his job and ends up homeless as a result. [=SpongeBob=] finds him and takes him into his home until he can find a new job. He takes it too far and stays a lot longer than necessary, turning [=SpongeBob=] into his personal slave (even forcing him to wear a ''[[DraggedIntoDrag maid's uniform]])''. While [=SpongeBob=] doesn't completely lose his temper, he snaps a bit and drops some '''very''' obvious hints that Squidward should go look for a job already. Squidward still doesn't get said hints (or, more likely, deliberately chooses to ignore them), so [=SpongeBob=] ''furiously'' takes Squidward, still in bed, all the way to the Krusty Krab. He tries to convince Mr. Krabs to hire Squidward back, and when that didn't work, the sponge finally snaps, outright ''strangles his boss'', calls him a cheapskate, and finally yells at him on how stupid the situation is (which in turn causes the first dime to appear -- [[ShaggyDogStory it was in Mr. Krabs' pocket the whole time!]]). It shows that even ''[=SpongeBob=]'' [[RageBreakingPoint has his limits...]] and it used to be the page image for a ''good'' reason.

** Hei Bai is a kind forest spirit--after all, who would fear an entity who takes the form of a [[PandaingToTheAudience panda]]? Messing with his forest is still a bad idea.

* ''WesternAnimation/{{Arthur}}''

* ''Franchise/DonaldDuck'': In ''Donald's Better Self'', [Donald's shoulder angel may be resistant to fighting at first, but as his shoulder devil learns the hard way, even he has his limits.

** Blossom. She is friendly, calm, and sweet, but she's amazing at kicking bad-guy buttocks. Also, in "Slave The Day", she yells at Big Billy.

* ''WesternAnimation/TheSpectacularSpiderMan'': Just like the comics,Spider-Man is an example.

** Spinel counts as this as well, understandable when you know what happened to her before the series even began. When she's cheerful, she's the loveliest friend you could ever dream of. When provoked, Spinel has the ability to take out the Crystal Gems AND Steven, [[spoiler: bear in mind he is [[DidYouJustPunchOutCthulhu Pink Diamond,]]]] without any difficulty.

** Lovable and quirky Beast Boy, who usually runs away from anyone powerful and evil, when sufficiently provoked is [[LetsGetDangerous quick to bring the pain]]. All of which are surpassed by the penultimate episode of Season 5 (which starts off with his growling "NOW try and follow me!" and blowing up some fallen robots, right after the Brain is done gloating over his victory over '''all''' the other Titans), in which Beast Boy assembles a rag-tag team, leads it properly, and takes on '''all of the show's villains''' at the same time. He closes it by quipping "Brain Freeze", after freezing the Brain. Never cross a guy who can [[Animorphism turn into some of nature's most powerful and dangerous animals]].

** Arnold tries to see good in everybody and is always willing to help someone out. If you're beyond reforming, he will not hesitate to let you know. The maddest Arnold has ever been was most likely when he helped [[LazyBum Oskar Kokoshka]] get a job as a newspaper deliveryman only for the latter to [[PlayingSick feign illness to get out of it and manipulate Arnold into doing it for him twice in a row]]. Arnold told Oskar he was a "huge loser" while [[TheReasonYouSuckSpeech calling him out on his lies]].

** At the climax of ''WesternAnimation/LendAPaw'', Pluto's [[GoodAngelBadAngel shoulder angel]] gets fed up with being pushed around and gives Pluto's shoulder devil what-for.

* [[TheChick M'gann]] from ''WesternAnimation/YoungJustice2010'' is a sweet bubbly girl most of the time. She also turns out to have PsychicPowers that dwarf those of any other Martian her uncle has ever met. When the villain [[EvilCounterpart Psimon]] threatens to expose her greatest secret -- the fact that she's [[spoiler: actually a White Martian, not a Green one]] -- she's willing to do anything to stop him -- including knocking her own friends unconscious before they can see her, then [[MindRape Mind Raping]] Psimon into a coma.
