History TheDogBitesBack / WesternAnimation

* On many ''WesternAnimation/LooneyTunes'' and TexAvery cartoons, a silly little character will come out of nowhere as a RunningGag. Eventually, the villain would get fed up and ask him who he is. The response: "Why, don't you know? I'm the hero in this picture", followed by a HyperspaceMallet to the head.

*** He really did this two-fold. Batman is obviously not one of the Joker's underlings, but Batman did spend a series enduring the latter's verbal and physical assaults and crazy plots while maintaining as calm of a facade as he could. But when the Joker kidnapped and tortured Tim Drake, this sent Batman over the edge. Bruce would've likely had no qualms killing him if Drake hadn't done it first.

** Harley Quinn also attempted to do this regarding the Joker twice: First was in the episode where he tried to destroy Gotham City with a nuclear device (since he was perfectly willing to abandon her and their friends among the other inmates, AND Harley's much beloved pet hyenas), downing the Joker's plane by shooting him in the head with her grappling hook, causing him to shoot the plane down himself. The second time was when she met Poison Ivy and attempted to kill The Joker for his earlier abuse towards her when it went too far. It's subverted twice: First, when she had the perfect opportunity to kill him when they meet again face to face, it turns out she was using a bang flag gun, and the second time, she ends up just forgiving him when he apologizes, to Poison Ivy's disgust.

*** The ''WesternAnimation/JusticeLeague episode "Twilight (Of The Gods)" has Superman in response refusing to help Darkseid when Darkseid in turn needs the League to save Apokolips from Brainiac, thinking "If you're a God against a planet destroyer, ''save your Own Self, because '''I''' won't.''" And knowing Darkseid might be trying to sucker the League. Batman calls Superman on that, but what does Superman say at the end? "You know Bruce...you're not always right."

* In later seasons of ''FamilyGuy'', the Griffin's punching bag Meg has been prone to more psychopathic outbursts, leading to several occasions [[OhCrap they realize too late they can actually push her too far]]. She has dealt a NoHoldsBarredBeatdown to both [[AbusiveParents Peter]] and her high school bully Connie D'maico for example.

* ''JonnyQuest'' TOS episode "Dragons of Ashida" has an island ruled by a mad YellowPeril scientist experimenting with genetically modified lizards and his YellowPeril bodyguard, a hulking brute who is the only one able to train the savage beasts. Dr. Ashida bullies, abuses and slaps Sumi several times throughout the episode, until Sumi decides he's not going to take it any more, hoists his "master" off of his feet and throws him to the lizards, which kill and eat him. Unlike most examples of this trope, Sumi did not take advantage of Dr. Ashida's weakness, nor did he die while exacting revenge (though FridgeLogic suggests that when the authorities arrive, they drop down on Sumi's head as they would have originally done Ashida).

*** The JusticeLeague episode "Twilight (Of The Gods)" has Superman in response refusing to help Darkseid when Darkseid in turns needs the League to save Apokolips from Brainiac, thinking "If you're a God against a planet destroyer, ''save your Own Self, because '''I''' won't.''" And knowing Darkseid might be trying to sucker the League. Batman calls Superman on that, but what does Superman say at the end? "You know Bruce...you're not always right."

* On a related note, thirteen episodes of ''TomAndJerry'' had Jerry getting his comeuppance by Tom, almost always when Jerry dealt the first blow or took his retribution to far too vindictive levels.
* Muttley will take physical abuse from [[WesternAnimation/WackyRaces Dick Dastardly]] just so far before he literally bites back. And he enjoys it, too, not only on ''Wacky Races'', but also on ''YogisTreasureHunt'' and ''DastardlyAndMuttleyInTheirFlyingMachines''.
* After Ms. Finster ends up injured from accidentially slipping on some candy (or so it would seem), virtually all of the kids on the playground took advantage of her current injury by ensuring that her running the playground would result in her experiencing a living hell as revenge for her strict policies. It's deconstructed in the ending.

* ''SheRaPrincessOfPower'': In "A Loss For Words", Mantenna jumped at the opportunity to drop Hordak down the same trap door Hordak usually drops him down.

* The Disney's Disney/{{Aladdin}} sequel ''The Return Of Jafar'' begins [[spoiler: and ends]] with Iago turning his back on Jafar after one insult too many.

* In the Porky Pig cartoon "The Case of the Stuttering Pig", the villain [[BornInTheTheatre brags to the audience]] that there is nothing they can do to stop him. "Especially ''you!'' You in the third row! You big softie!" In the end, the villain is dispatched by a theater seat hurled into the screen...

* On a related note, three episodes of ''TomAndJerry'' had Jerry getting his comeuppance by Tom.

* In the ''WesternAnimation/SouthPark'' episode "Christian Rock Hard" after Cartman suffers a HumiliationConga due to his plan to show up Stan and Kyle failing, Butters, who like in most of his schemes is playing the role of his underling, then adds one more humiliation to top it off by farting Cartman's face and flipping him off.
** And in the same episode, Cartman was constantly being racist and treating Token like crap. Token finally has enough and beats the crap out of him.

* Baxter Stockman of ''Franchise/TeenageMutantNinjaTurtles'' fame is an often abused and mistreated lackey of the Shredder, and in both the [[TeenageMutantNinjaTurtles1987 1987]] cartoon ("Curse of the Evil Eye") and [[TeenageMutantNinjaTurtles2003 2003]] cartoon ("Return to New York") he's eventually attempted a nearly-successful coup to destroy both the Turtles and his master after reaching the breaking point. If anything, history will likely repeat itself in the [[TeenageMutantNinjaTurtles2012 2012]] cartoon.

* A mild case in ''[[GeorgeOfTheJungle Tom Slick]]''. One episode featured a racing couple. The wife constantly berated the husband. In the end, he told her to "shut up". She actually started to respect him for it.

** The same trope ultimately [[spoiler:causes the death of the Animated Series Joker]]. As revealed in ''BatmanBeyondReturnOfTheJoker'', the Joker kidnapped Tim Drake, the second Robin, and subjected him to torture and a steady stream of mind-altering drugs. [[spoiler:He molded him into a "Joker Junior" in order to hurt Batman, and, after gaining the upper hand on the Dark Knight, tossed a lethal trick gun to Robin. Instead of shooting Batman, [[HoistByHisOwnPetard Robin turned the gun on the Joker and killed him]]]].

* In ''TheSimpsons'', when Homer has to take over Smithers' duties to Mr. Burns while Smithers goes on vacation, Homer was frequently met with a large amount of abuse by Mr. Burns. Eventually, he reached his breaking point and ended up ''punching'' Mr. Burns in the eye, initially fearing he killed him when he actually survived, but was also deeply traumatized by the event. Smithers chose Homer so Mr. Burns would want Smithers back, but it backfired.
* Muttley will take physical abuse from [[WackyRaces Dick Dastardly]] just so far before he literally bites back. And he enjoys it, too.

* In the two-part season 3 premier of WesternAnimation/MyLittlePonyFriendshipIsMagic, King Sombra enslaved the crystal ponies, and when he was [[SealedEvilInACan defeated]] he cast a curse to make the empire vanish for a thousand years. After their return, the mere memory of Sombra brings the crystal ponies pain, and they react with extreme fear when he returns. Then, after [[spoiler: [[BigDamnHeroes Spike]]]] retrieves the Crystal Heart, the crystal ponies, along with Princess Cadance (who incidentally has been losing energy trying to protect the empire from Sombra), unleash the power of the Crystal Heart, which [[LiterallyShatteredLives destroys]] Sombra.
