* In the ''ComicBook/{{Asterix}}'' story ''Recap/TheMansionsOfTheGods'', [[DreadfulMusician Cacofonix]] being evicted from the titular mansions serves as the Gauls' ''casus belli'' to tear them down. It helps that Cacofonix had already driven away all the civilians with his singing already and the mansions were occupied by the Roman soldiers.

** Whitebeard is such a PapaWolf to his subordinates that he's willing to go to an all-out war if one of them gets in danger. This is pretty much what started the Marineford arc.
** Arlong is like this. If any human attacks one of his henchmen, it'll mean bringing down the wrath of the entire Arlong Pirates- if you're ''lucky'', they'll only kill you. If you're ''unlucky'', they'll wipe out your entire town and god knows how many of your neighbors as an 'example' to the other towns they control.

** Article 5 came under the spotlight once again when UsefulNotes/{{the New|Russia}} UsefulNotes/{{Russia}} launched a full scale invasion of UsefulNotes/{{Ukraine}}. Many lament that the latter country was prevented from joining NATO as soon as 2008, which gave UsefulNotes/VladimirPutin much leeway, while the opposite likely would have prevented said invasion (and likely the 2014 annexation of Crimea and war in Donbas).

* Article 5 of the NATO charter explicitly states this. It was originally envisaged to discourage the Soviet Union from getting too expansionist in Europe, as any attack on a NATO country would draw every other member into the war -- most notably, the United States and its nuclear arsenal. Thankfully, it never was invoked against the Soviet Union; the only time NATO has ever invoked Article 5 was after the September 11 attacks in the United States.
** These good intentions were strained twice in TheSeventies, when NATO was forced to ask what would happen if two of its member states were dragged into a shooting war... ''with each other''. Iceland and Britain exchanged shots in a disagreement over fishing rights. Then, more seriously, Greece and Turkey ended up on the brink of all-out war over Cyprus. As a politician pointed out at the time, it makes the all-for-one principle a little bit less clear cut, as well as bloody embarrassing.[[note]]The Warsaw Pact had its woes too - what with invasions of Hungary and Czechoslovakia by the fellow alliance members...[[/note]]

* ''LightNovel/SoImASpiderSoWhat'' has Anogratch, a monkey-like monster. Killing one will cause every single anogratch in large radius to target whoever killed the original one, and killing those causes more to get enraged. They are downright suicidal in their pursuit, to the point of actively sacrificing themselves to give their brethren a chance to kill the offender. [[spoiler:The Demon army successfully takes down a human fort by sneaking in one and letting humans kill it, causing a massive herd of anogratch to overrun the fort. The downside is that now not even demons can take the fort from its new residents.]]

** In the prequel ''[[Recap/BabylonFiveFilm01InTheBeginning In The Beginning]]'', the disastrous first contact event that results in a Human attack on a Minbari fleet which kills their leader Dukhat is taken as an assault on the entire Minbari race, and they embark on a genocidal holy war of revenge.

* In ''Film/SpiderMan1'', the Green Goblin tries to force Spidey into making a SadisticChoice - save his LoveInterest, or a bunch of school children? What Goblin doesn't expect is for all the people on the bridge to try to help Spidey by pelting him with various objects. Over the din, two men's voice can be heard shouting:

'''Mal''': Oh, but ''you did'', Jayne. You turn on ANY of my crew, you turn on ME. But since that's a concept you can't seem to wrap your head around, then you got no place here. You did it to me, Jayne, and that's a fact.

* ''Manga/FairyTail'': The ''Fairy Tail'' Guild itself. Hurting ''any'' of their members is the same as declaring war. The best example is the Phantom Lord arc. The Phantoms trash their guild hall? They turn the other cheek. [[spoiler: [[KickTheDog Attack some of their weaker members and crucify them on a tree?]]]] [[RoaringRampageOfRevenge Nice knowing ya.]] And when it turns out [[spoiler: they were actually hired to kidnap [[TheChick Lucy]], they make sure that no one can get near her, despite the threat of [[WeaponofMassDestruction annihilation]].]]

* In the ''Literature/GentlemanBastard'', series, the Bondsmagi are {{Super Supremacist}}s who have a simple rule for dealing with non-mages: they do whatever they want, and any harm to a Bondsmage is answered with ''ruthless'' DisproportionateRetribution.

--> '''Burgess''': "Thank you for taking this (her sister's rape) on."
--> '''Voight''': "An attack on your family is an attack on ''our'' family."

** Played very straight with the dwarfs. Harm a dwarf without immediate recompense, and you [[ThisIsUnforgivable create a Grudge]] [[RevengeBeforeReason that dwarf will spend the rest of their life trying to pay back]]. If they fail or die, their family picks up the slack. Then their hold. If left unanswered long enough, your Grudge will end up copied into the Great Book of Grudges held by TheHighKing, at which point getting revenge on you ([[AndYourLittleDogToo or whatever descendants or community you leave behind]]) becomes a sacrament for the Dwarf race itself. Oddly enough, a culture based entirely on collective revenge for harm done to individuals has rendered the Dwarfs something of a DyingRace.

* Subverted in ''TabletopGame/WarhammerFantasy'', where Brettonian nobles who go full FeudalOverlord (including DroitDuSeigneur) can look forward to being besieged by a coalition of their neighbors. Not for the peasants' sake, of course, dirty, filthy little mongrels, but because such a thing reflects badly on all Brettonian nobs.
