History BewareTheNiceOnes / WebOriginal

* In Literature/DeadWest, Gervas, the narrator is a KindHeartedCatLover, and a perfect gentleman. Cross him, and expect to be pulverized. The Porcelain Doctor is this combined with BewareOfTheQuietOnes; he is the sweetest, most polite, meek Bishounen in dainty glasses and always dressed sharply. But if you press a BerserkButton, prepare to die. The effect is more shocking since his aura will make you look at him like the most fragile and precious little thing in the world.

* Jay from ''WebVideo/MarbleHornets''. He is a normal, nice guy who tries to find out what goes on around him and his friends, but if, say, [[Franchise/TheSlenderManMythos The Operator]] does stuff like threaten Jessica, he will ''[[DidYouJustPunchOutCthulhu tackle]] [[{{Badass}} and wrestle]] [[CrowningMomentOfAwesome him]],'' even if it gives him 7 months of LaserGuidedAmnesia.

* ''TheGunganCouncil''. Io Akima seems to be one of the most lovable, playful persons around. That is, until Adira smashed her datapad, which was a gift from a friend that had died. Cue Io going from wanting to tease Adira to outright attempting to murder her.

* Codex of ''TheGuild'' is shy and accommodating to the point of being an ExtremeDoormat, but when she found out her boyfriend had dumped her for another man she set fire to his cello.

* TheAnnoyingOrange: It pays not to anger Marshmallow, even the title character warns about this, through Grapefruit found this [[https://www.youtube.com/watch?v=56SA_C9o9VU out the hard way]].

* In the web serial ''Literature//AshAndCinders'', Cinder first stands up for herself when she [[TakingYouwithMe threatens to kill the Forest Queen and the rest of her kingdom]] if they refuse to give her her brother back.

** In fact, let's put the entirety of Team Kimba, plus Carmilla, on the list. Hell, through in Aquerna and Dragonrider while you're at it, as they've both been shown to bring the whoopass when needed.

* Gohan's adherence to this trope is parodied in ''WebVideo/DragonBallZAbridged''. When he is a shy, meek, nerdy kid with good manners, a lot of the characters in the series abuse him in hiarious manners. When he loses it ([[PrecisionFStrike And you'll know it when he does]]), it's a sign that someone is going to get hurt.

* In ''WebAnimation/DeathBattle'', between two combatants, if one of them is nice and the other pretty much isn't, the nice one usually ends up winning.
** [[WesternAnimation/MyLittlePonyFriendshipIsMagic Rainbow Dash]] ''only'' attacks [[Franchise/TransformersGeneration1 Starscream]] when he threatens to kill her, [[spoiler:then delivers a [[CurbStompBattle thorough beating]]. Then, she '''[[YourSoulIsMine eats]]''' his [[OurSoulsAreDifferent Spark]]!]]
** [[VideoGame/YoshisIsland Yoshi]] is described in the intro as a "cute, happy dinosaur". [[spoiler:His fight with [[VideoGame/KillerInstinct Riptor]] ends with him throwing the ferocious fighter over a cliff, after drenching the latter's face [[HoistByHIsOwnPetard in his own acid]].]]
*** This one is particularly notable as for most of the fight, Yoshi just stands there getting beat up.
** [[Franchise/SuperMarioBros Princess Peach]], the somewhat ditsy, happy-go-lucky girl who can't take ten steps without getting kidnapped, [[spoiler:kicks [[Franchise/TheLegendOfZelda Zelda's]] face so hard [[YourHeadAsplode her head explodes]].]]
** And then there's the loud-mouthed, fun-loving {{Spider-Man}} [[spoiler:slingshot-kicking Franchise/{{Batman}}'s torso off?]]
** [[Anime/DragonBallZ Goku]] vs. Franchise/{{Superman}} is a battle between two incredibly friendly and kind, not to mention incredibly powerful beings. Goku is noted as being a family man outside his fights, and Superman is... well, Superman. [[spoiler:Their clash results in the utter destruction of the Earth, and it's implied Superman was ''still'' holding back tremendously]].
** [[WebAnimation/{{RWBY}} Yang Xiao Long]] is, BloodKnight tendencies aside, a laid-back teenage girl who's fond of puns and a joy to hang out with. [[spoiler:She also brutally kills Tifa via {{Recoil Boost}}ed NeckSnap]].

** [[WebAnimation/{{RWBY}} Yang Xiao Long]] may be a Huntress in training who wants to travel the world and [[BloodKnight fight everybody just for the thrill of it]], but she's a also fun-loving and laid-back teenage girl who's famous for her puns and a joy to hang out with. [[spoiler:Sure enough, she initially treats her clash with Tifa as a fun bar brawl, but eventually, once Tifa has injured her and - worse - [[NobodyTouchesTheHair messed with her hair]], Yang goes all out against Tifa, shatters her weapon, pounds the absolute crap out of her and finishes her off by ''violently snapping her neck!'']]

* ''WebVideo/{{Carmilla}}'': Laura Hollis, AllLovingHero, truly wants to save everyone possible at her CrapsackWorld AcademyOfAdventure. She's an upbeat, eager [[TheDeterminator Determinator]], who will withstand utter hell if it will keep people safe. But if you [[BreakTheCutie push her too far]], she ''will'' break... and chances are ''very good'' that you will not survive. When she crosses her DespairEventHorizon in season two she [[spoiler: flat out kills [[CompleteMonster Vordenberg]]]], and then there's her actually ''ordering'' [[LesbianVampire Carmilla]] to kill the cannibal baker in the Christmas Special...

* In Literature/SuperPowereds, hurting people Vince cares about is a ''very'' bad idea. Best exemplified at the end of Year 2, when [[spoiler: he has a vision of a girl from his past dying and goes on a rampage]], and near the end of Year 3 when [[spoiler: Sasha dies and he [[TranquilFury goes to kill]] the man who did it.]]

* Skitter from Literature/{{Worm}} is in many ways the nicest of the Undersiders, a group of villains [[spoiler: trying to take over Brockton Bay]] and will go to any lengths for those she takes under her protection, even for complete strangers. She's also the most powerful, dangerous and terrifying of the group, despite it containing darkness manipulators and a girl with an army of monster dogs. This is because she wants to use her power for good and has resolved to make full use of intimidation to scare people into submission rather than harming them and, failing that, is prepared to use brutal combat pragmatism to take down stronger threats that herself as quickly as possible.

* [[ChakonaSpace Chakats]] are usually nice to a fault -- empathic, social, family-oriented, and almost too good to be true except that they normally actually are; their designers did a good job. ''Don't'', however, threaten one's cubs or even hir best friends and family will have trouble keeping hir from shredding you on the spot...

* Alfred, the [[TheBigGuy massive]] construction worker from ''DarwinsSoldiers'', is explicitly described as not "the kind of person to pick fights". And it takes a lot to provoke him into physical action. But anger him enough and you'll see why angering someone with SuperStrength is ''[[TemptingFate extremely]]'' [[TooDumbToLive stupid]]. His most extreme case was when he got so angry that he threatened ''to dismember someone and beat them to death [[GrievousHarmWithABody with their own limbs]]''. And if [[TheHero Dr. Zanasiu]] hadn't calmed him down, there was no doubt he would have done so.

* The title character of ''Erika's New Perfume'' is normally a loving, soft spoken ShrinkingViolet, but when [[BigBrotherBully Big Sister Bully]] Marie tries to [[spoiler:reverse [[CoolBigSis Sarah's]] PlotRelevantAgeUp,]] she ''snaps'' and lays into her with an epic combination TheReasonYouSuckSpeech / WorldOfCardboardSpeech that leaves her flabbergasted. In a ''wet diaper,'' no less.

* In ''EndlessSaturdays'', Kara, while perhaps the most quiet and normal of the three, gets annoyed enough by her siblings to try and ensure that they get permanently lost in the wilderness.

** Another is a [[http://scp-wiki.wikidot.com/scp-054 sentient mass of water that takes the form of a woman]]. She's was nice friendly to male staff, but the experiments performed on her by them traumatized her so much, she finally had enough and lashed out at them which temporarily changed her object class to Euclid.
