History Main / MistreatmentInducedBetrayal

* ''Fanfic/RoseRedemptionAU'': Fire Agate was a loyal member of Pink Diamond's court that fought valiantly for her diamond against the rebel army, unaware that Pink Diamond was also the leader of that army Rose Quartz. When she believed that her diamond was shattered, Agate was devastated, having been given Fire Pearl as something of a companion to help her stay together. When she discovered the truth, she vowed revenge on Pink on behalf of herself and the many loyal gems that were shattered in the war.\

[[AC:''Franchise/TeenTitans]]

--> '''Nedry:''' Don't get cheap on me, Dodgson. That was Hammond's mistake.

* ''Film/TheLadykillers2004'': [[spoiler: Pancake]] tries to steal the money from his partners largely out of bitterness that none of them besides Lump [[spoiler:voted to give him an extra share after he lost a finger handling the explosives.]]

* Mentioned in ''Literature/ABrothersPrice'': Ren, after [[spoiler: seducing]] the Whistler family's [[spoiler: son, Jerin, on the kitchen floor]], fears the Whistlers will lure her into a trap. [[spoiler: They don't, in fact, the family doesn't know about it, yet.]] Ren is not a villain but sometimes acts like a jerk, as the spoilered incident proves.

* In the Literature/ModestyBlaise novel ''A Taste for Death'', Modesty and Willie invoke this trope, persuading one of the villain's underlings to help them by manufacturing evidence that the villain plans to dispose of him along with the prisoners when their usefulness is at an end.
* Franchise/StarWarsLegends:

* In Creator/EdgarRiceBurroughs's ''[[Literature/JohnCarterOfMars Chessman of Mars]]'', I-Gos greatly admires courage and comes to see how Tara and Turan show such courage as he has not [[GoodOldWays seen in centuries]]. And then his jeddak calls him "doddering fool"--a point he repeats to Turan in explaining that [[{{Turncoat}} he wants to help him now]].
* Inverted in ''Literature/{{Animorphs}}'' during the David Trilogy. The Animorphs think they're saving David from infestation, a FateWorseThanDeath, by making him their new SixthRanger, but as this happens in rather desperate circumstances that means he's more or less forcibly recruited, kidnapped, and thrust into a battle he wants no part of, thrown into the deep end in a way they weren't and separated from his family. He tries making the best of it for a little while, but after team leader Jake threatens to [[DisproportionateRetribution kill him for breaking into a hotel room]] he has enough. As soon as the BigBad offers to give him his family back he goes SixthRangerTraitor on them. In context, though, Jake disliked David long before the "hotel room" incident. It was more like Jake snapped because of a series of minor infractions on David's part, such as when David kills a crow ''for the fun of it'' while in morph and then lying about having lost control of his morph.
** In the endgame of the series, the unnamed Yeerk infesting Jake's brother Tom head a faction that turns on Visser One ([[MeaningfulRename formerly Visser Three]]), the head of the Yeerk invasion of Earth. Visser One is a textbook BadBoss prone to YouHaveFailedMe and who's burned through all his friends and allies over the course of the series; Tom's Yeerk can put two and two together and sees that loyal Yeerks won't flourish on a conquered Earth, so he [[EnemyMine throws in with the Animorphs]] for long enough to steal a ship and leave for somewhere else.
* In ''Literature/HarryPotter'', a couple of Voldemort's lieutenants go this way. A big deal is made of Voldemort's [[EvilCannotComprehendGood inability to comprehend human emotion]] and how he doesn't trust (or even particularly like) his underlings.
** Severus Snape [[spoiler: defected from the Death Eaters and became a spy for Dumbledore after Voldemort decided to kill the Potters, endangering his childhood love, Lily Evans (now Potter, yes as Harry's mother)]]. Granted, it was a bit more complicated; [[spoiler: Voldemort did make some effort in sparing Lily, but she refused to move out the way and let Harry die and Snape joining was also for him being TheAtoner. The only reason Voldemort went after the Potters in the first place was because of a prophecy that ''Snape'' overheard and told Voldemort himself]].
** In a FaceHeelTurn variation, this is what causes Kreacher to betray Sirius to the Death Eaters in ''Literature/HarryPotterAndTheOrderOfThePhoenix'': Sirius was justifiably upset at being forced to live in a house he hates with a painting that constantly hurls verbal abuse at him and a house elf that does the same. But Sirius's mistake was that he took out his anger on Kreacher, who was working for the hated Black family but had not actually caused Sirius harm in any way. Well, not caused Sirius harm before the "betrayal" part, anyway. It was Harry realizing this and extending his hand to Kreacher that causes the house-elf to truly become an ally to Harry.
** A mild FaceHeelTurn version: Percy Weasley is constantly pranked, insulted, and mocked by his siblings, particularly his twin brothers, while Harry Potter is quickly welcomed into the Burrow as practically an adopted son. Percy never directly witnesses any of Harry's heroics in the first four books (well, outside of saving his brother in Book 4), so it's not that surprising that when he is given a promotion at the Ministry of Magic, a promotion which his father Arthur Weasley flat out says he didn't earn and that his boss only wants to use Percy to spy on the Order, etc, he shuns all contact with his family, determined to prove that he is not the sort of man who blindly follows Dumbledore like all the other Weasleys supposedly do. Unfortunately, Dumbledore turned out to be ''right'', and Arthur probably wasn't far off the mark either. ([[JerkassHasAPoint Even if he was less than tactful about it in the heat of the moment.]])
* Odile in ''Literature/TheBlackSwan'' (Creator/MercedesLackey's retelling of ''Theatre/SwanLake'') turns on her father after he uses her as a {{People Puppet|s}} to deceive Siegfried.

* In ''[[Literature/HonorHarrington Field of Dishonor]]'', [[AristocratsAreEvil Pavel Young]] compels his (female) security chief to become his lover. This leads her to give Honor Harrington's allies evidence that implicates Young in the murder of [[spoiler:Honor's lover, Paul Tankersley]], ultimately leading to [[spoiler:Honor killing Young in a duel]]. She even notes how stupid he is to abuse his security chief this way.
* In Creator/MichaelFlynn's ''Literature/SpiralArm'' novel ''On the Razor's Edge'', the Radiant Name orders his men to stay put, though he has armor and a teleport device, and they don't, right before one [[spoiler:assassinates him]].
* In ''Literature/TheDresdenFiles'':
** In ''Literature/BloodRites'' [[spoiler:Lara Raith has been abused, mentally and sexually, by her father for decades. Her mind is very eager to turn against him but fear of his terrifying power kept her from acting. When Harry gets him to confess that he has no power or means of replenishing it until the descendants of the woman who cursed him are killed, namely Harry, and even Lara can be replaced if she proves to be an inconvenience to him, it is enough for her to break free and take him down]].
** ''Literature/WhiteNight'' has a unique version with guaranteed mistreatment to come causes the betrayal when Harry gets [[spoiler:Lash, the shadow of a Fallen Angel in his head, to admit if Harry does take up the Coin of Lasciel, she will effectively be killed by being reabsorbed into the true Fallen. As she has existed in Harry's head for years, she is more than just the simple copy of the ageless Fallen. This was one step in the many that would lead Lash to choose to fully separate herself from the Fallen Angel and become something different]].
* ''Literature/TheBookOfMormon'' mentions how Morianton very nearly led away a large group of Nephites to settle the "land northward", which would likely have compromised the Nephites' defensive line against Lamanite invaders (plus, the reason Morianton wanted to run was that his people had tried to cheat one of their neighbours, and he knew the civil government would rule against him). Before he can leave, though, he makes the mistake of beating up one of his servants in a fit of temper; she runs straight to Chief Captain Moroni and spills everything, allowing him to intercept and stop the runaways.
* In ''Literature/JurassicPark'' Nedry chooses to sell Ingen's secrets to its competitors in large part because Hammond was such a cheapskate and BadBoss, having forced Nedry to program the park's entire computer network by himself ([[CuttingCorners instead of hiring a full team of programmers]]) while paying him low wages and keeping him on the island for long periods of time. So much for sparing no expense.

* In ''Literature/PercyJacksonAndTheOlympians'', Luke and numerous other demigods join the Titans because they're sick of their godly parents mistreating and neglecting them all their lives and leaving their mortal parent to fend for themselves. The gods also outright ''forget'' to claim their children after they arrive at Camp Half-Blood, leaving them wondering who their divine parent even is. The good guys even acknowledge that [[BlackAndGrayMorality while the Olympians may be overall better than the villains they are fighting against]], [[VillainHasAPoint they sure aren't what they would call good]].
* In ''Literature/{{Destroyermen}}'', the entire crew of the [[spoiler:German sub ''U-112'']] ends up surrendering to [[spoiler:the Alliance]] after being essentially written off by [[spoiler:the League of Tripoli]]. In addition, they know that [[spoiler:the French and Italians are already working to marginalize the German contingent of the League]].
* ''Literature/ASongOfIceAndFire'':
** Cersei spends the whole of ''Literature/AFeastForCrows'' in her capacity as [[RegentForLife regent for King Tommen]] insulting and ignoring the advice of her brother Jaime, her uncle Kevan and Grand Maester Pycelle (as well as periodically threatening the latter with imprisonment and/or death), both alienating them and running Westeros into the ground. When the ([[DidntThinkThisThrough thanks to Cersei]]) newly empowered [[ChurchMilitant Faith Militant]] imprison Cersei on charges of treason and adultery, Jaime ignores her [[AintTooProudToBeg pleading request]] to be her champion in a TrialByCombat, while Kevan and Pycelle leave her in jail, strip her [[YesMan sycophants]] of power and get to work trying to fix the mess Cersei made.
** A historical example from ''Literature/FireAndBlood'': [[spoiler: after defeating and [[FedToTheBeast executing his half-sister Rhaenyra]], King Aegon II imposes heavy fines on the lords of the Crownlands to punish them for supporting Rhaenyra's claim to the Iron Throne. When an enemy army fighting to depose him and put Rhaenyra's son on the throne moves to attack King's Landing, Aegon commands the same lords to provide soldiers to reinforce his loyalists...and in the battle that follows, they either [[BetrayalByInaction abandon Aegon's loyalists to be massacred]] or [[CavalryBetrayal assist in the enemy victory]], leaving Aegon left with no forces to defend the city against three enemy armies who want his head on a spike. When he threatens one of his remaining commanders to either stop the enemy or [[IWillPunishYourFriendForYourFailure see his granddaughter executed as punishment]], the man quickly joins a conspiracy to assassinate Aegon before the end of the day]].
* In ''Literature/LastFlight'', set in the ''Franchise/DragonAge'' universe, the Tevinter Imperium closes its borders and refuses to supply military aid to the southern nations battling against the darkspawn of [[TheEndOfTheWorldAsWeKnowIt the Fourth Blight]] because those same nations spent the last 70 years trying to subjugate Tevinter in a series of religious wars at the Chantry's behest.
* In ''Literature/HeraldsOfValdemar'', Nyara hasn't known friendship or kindness since she was younger. She and her siblings were used as a GuineaPigFamily for her AbusiveDad, Mornelithe Falconsbane, as he tested mutations he wanted to use on himself on them. Only Nyara survived, as he [[OffingTheOffspring killed]] the "failures". He also installed a VillainOverride on her, enjoying that she loved and [[ParentalIncest needed]] and ''despised'' him. She runs away early in ''Winds of Fate'', helping his enemies out of spite and EnlightenedSelfInterest, and immediatley doubles down on resisting him when he calls her back so he can use what she's learned to hurt the very people who took her in and were good to her. Nyara goes as far as attacking him after he hurts [[DefectingForLove Skif]].

* Franchise/MarvelCinematicUniverse:

* ''Series/SleepyHollow'': [[spoiler: Henry]] is loyal to Moloch since Moloch saved him and took him under his wing after he was abandoned by [[spoiler: his parents]], though they had good excuses. This lasts until the season 2 fall finale when Moloch repeatedly states that [[spoiler: Henry]] is disposable and makes it clear that Moloch does not care about anyone other than himself. This inspires [[spoiler: Henry to kill Moloch]] to save the protagonists.
* ''Series/StargateSG1''

* In ''To Play the King'' (sequel to ''Series/{{House of Cards|UK}}''), Prime Minister Francis Urquhart implicitly reneges on his promise to appoint his hatchet man Tim Stamper to his cabinet. [[spoiler: Stamper tries to expose Urquhart as a murderer, in revenge, but Urquhart has him killed first.]]
* ''Series/ProvenInnocent'': Just as it looks like Sarah Bukhari is going to lose her appeal, the deputy prosecutor in her case suddenly announces that she'll accept a plea to a lesser crime and offer a sentence for time served. The deputy prosecutor does this after getting tired of the sexist, condescending judge talking over her there for the whole trial.
* A major plot point in Season 3 of ''Series/{{Narcos}}''. Jorge Salcedo is a security expert who worked for the Cali Cartel for many years. After learning of their plan to go legit in six months, he plans to retire and start his own legit security business. However, Miguel Rodriguez, one of the leaders of the Cartel forces him to stay on, throwing a wrench into his plans. It's also revealed that despite his expertise, and providing solid security for the Cartel for years, he isn't respected by many members of the Cartel because he refuses to get blood on his hands, including David Rodriguez who constantly looks for an excuse to kill him, but is stopped by his father Miguel. [[spoiler: After seeing his best friend and fellow security head tortured and murdered by David along with his wife for the arrest of Gilberto Rodriguez, which wasn't his fault, Salcedo realized he's expendable despite his loyalty and contacts the two DEA agents in Cali. He makes a deal in exchange for him and his family getting out and put into witness protection.]]
* This is the theme of the ''Series/LegendsOfTomorrow'' episode "Egg [=McGuffin=]", running through all three plots. It's why the assistant of the egomaniac explorer stole the egg; it's Sara's theory as to who the killer is in the book she's reading; and it's [[spoiler: why Gary decides he's had enough of being the ButtMonkey and sides with Neron]].
* Featured twice in the [[OneEpisodeWonder pilot episode]] of ''W.E.I.R.D. World:''

* ''TabletopGame/BattleTech'':
** The Clan Smoke Jaguar warrior, Trent, suffered grievous wounds in the Battle of Tukayyid, which his Clan lost to [=ComStar=] and was subsequently forced into a ceasefire. After his lancemates claimed to have saved his life - [[ProudWarriorRace a sign of weakness]] - his [[HumongousMecha battlemech]] was sabotaged in a trial to earn his Bloodname, his being repeatedly ReassignedToAntarctica, and countless lies and backstabs by his superior officers, he snapped and betrayed the Clans. He was contacted by a [=ComStar=] deep agent and gave them the coordinates of the Clan's homeworld in exchange for the right to lead a battlemech lance in combat against his former allies.
** The Draconis Combine has a long history of mistreating and blackmailing mercenaries under their employ, the Eridani Light Horse and the Wolf's Dragoons suffered this when their dependents were held hostage and killed by their employers, prompting the units to turn on them and leave. When the Combine reinforcements sent to deal with the Light Horse learned what had been done to the mercenaries' families, they were so appalled that they disregarded their orders and left the surviving mercs in peace.
** The 21st Centauri Lancers were formerly part of the Cappellan Confederations armies, but when their commander hadn't paid them in 9 months, the unit mutinied and went on to work as mercenaries for the other Successor States.
** This is really something of a recurring theme in ''[=BattleTech=]'' fiction. Sure, mercenaries expect to be treated as expendable to some extent since it's mutually understood that their loyalty is for pay, but pushing things into "actively abusing or trying to cheat them" territory is by the same token pretty much ''never'' a good idea.

* The Duke of Buckingham in ''Theatre/RichardIII'' is a classic example: he helps Richard to the throne with the understanding that he'll get land and another title in return. When he goes to Richard to remind him of this promise, Richard first ignores him, then yells at him, at which point Buckingham promptly defects to the side of the rebels. [[HeelFaceDoorSlam Or tries to; he's found out pretty darn quickly and killed.]] Lord Stanley, on the other hand, gains nothing at all, is treated as a ButtMonkey servant, and defects successfully.

* Downplayed with the fake sea captain in ''VisualNovel/DoubleHomework''. Faced with the threat of physical violence from the protagonist and Morgan, he surrenders the ship, tells everybody who his employer is, and gives away the location of the server that supposedly contains everyone’s compromising photos. His reason? He isn’t being paid well enough.

* In ''WebAnimation/RedVsBlue'' season 15, [[spoiler: the vast majority of the surviving Sim Troopers pull this on the UNSC for [[KickTheDog selling them out to Project Freelancer]] so they could be [[CannonFodder target practice]] for their [[SuperSoldier Freelancers]], and Doc does this to the Blood Gulch Crew for their crap treatment of him. Only the Blood Gulch Crew doesn't do this, though [[DesperatelyLookingForAPurposeInLife Sarge still defects for other reasons]]]].
* In [[https://www.youtube.com/watch?v=7iy0J8wLaUs this]] [[WebAnimation/DorklyOriginals Dorkly]] video, Ash's Charizard turns on him, because it's "pissed about being held captive in a tiny ball." Unsurprisingly, Flamethrower is [[BlackComedy super effective at burning Ash's flesh.]]

* ''[[http://bloody-nipple.groboclown.net/0001.html The Bloody Nipple Saga]]'' (a CampaignComic adaptation of the first ''[[Film/ConanTheBarbarian1982 Conan the Barbarian]]'' movie), [[spoiler: Tom (the player who initially was playing Valeria)]] is eventually so disgusted by [[spoiler: Chris (Conan) and Michael (Subutai)]] lack of subtlety and roleplay that he eventually requests (which the DM accepts!) to end the campaign by playing [[spoiler: Thulsa Doom (yes, the Big Bad of the story)]].
* Iron Jane in ''Webcomic/EverydayHeroes'' [[https://eheroes.thecomicseries.com/comics/104 turns against her team leader]] [[spoiler:after she watches him kill her best friend]].
* In "Webcomic/ExperienceBoost", [[spoiler: Orhan loses practically all of the Order of Swords membership this way. His treatment of Theron and xMurderBanex directly leads to Theron exposing his collaboration with the Legion and Blackmail of Vedrana, causing half the guild to leave. The other half quits en masse after he explodes on his guildmates following a series of failed raids in a personal vendetta against Vedrana's raid progress.]]

--->'''Right-Eye:''' I'm what you would call your classic, "disgruntled employee."

[[AC:Franchise/MonsterVerse]]

* ''Fanfic/RoseRedemptionAU'': Fire Agate was a loyal member of Pink Diamond's court that fought valiantly for her diamond against the rebel army, unaware that Pink Diamond was also the leader of that army Rose Quartz. When she believed that her diamond was shattered, Agate was devastated, having been given Fire Pearl as something of a companion to help her stay together. When she discovered the truth, she vowed revenge on Pink on behalf of herself and the many loyal gems that were shattered in the war.

[[AC:Unsorted]]
* In Shadow [=Dragon8685=]'s ''Fanfic/MisfiledDreams'' Jenny Jr. has already been awed by the friendliness and compassion of Ash and Emily, so what better way for her [[ManipulativeBastard Manipulative Bitch]] of a mother to keep her on the side than by verbally abusing and disowning her. Jenny Jr.'s HeelFaceTurn is probably the easiest decision ever made as a result.
* In ''Fanfic/AnEntryWithABang[=!=]'', the Buron Cavalry decide to try and get in Clancy-Earth's good graces after they find out that C-Earth has nukes and Vorax did not mention as such beforehand. Aladdin Al Azim does the same after he realises that the Earthers he faces include Muslims and that Mecca is one of Vorax's targets.
* [[PlayingWithATrope Played with]] in ''WesternAnimation/TheLEGOMovie'''s ''FanFic/APieceOfRebellion''. When they find the Piece of Resistance, Bad Cop makes Good Cop take control because President Business is much harsher on his "good half", so he needs the credit more. Good Cop then accidentally kick-starts the plot by making a mistake that gets them labeled a traitor. Moreover, even after they got the Piece stuck to their back, Good Cop/Bad Cop were perfectly willing to hand it over to President Business like the loyal officer they were. Instead, Business declares them traitors and try to have them executed.
* ''Fanfic/ThousandShinji'': Gendo abandoned his son Shinji when he was four. When summoned to Tokyo-3 by his father ten years later, Shinji has learnt the ways of scheming and plotting, and several useful skills, and he decides to pay his father back. In the process [[EmotionlessGirl Rei]] -who had been treated as a tool for Gendo- and [[FieryRedhead Asuka]] -who had lost her mother and been turned into a {{Child Soldier|s}} cause Nerv and whom [[spoiler:Gendo forced to attack her best friend]]- side with him.
* In the ''Literature/{{Worm}}'' fanfic, ''Fanfic/{{Intrepid}}'', this is the reason Rune finishes her HeelFaceTurn in 8-01 because Kaiser electrocuted her for the sake of torture.
* The plot of ''[[https://www.fanfiction.net/s/8914586/1/Harry-Potter-Junior-Inquisitor Harry Potter: Junior Inquisitor]]'' is kicked off by Dumbledore throwing Harry under the bus by both recanting his statements about Voldemort's return and not defending Harry at his trial. As a result, Harry promptly throws Dumbledore under the bus in turn.

* ''Webcomic/ProjectRiribirth'' has an unusual example: Riri Williams goes after Tony in part because he was too '''nice''' to her, not too mean. As Riri sees it, if Tony hadn't overpraised her and convinced her that she was one of the world's strongest heroes, Riri wouldn't have jumped into a fight way above her weight class and gotten the NoHoldsBarredBeatdown that ended her superhero career permanently.
* ''[[https://www.fanfiction.net/s/174494/1/Force-of-Destiny Force of Destiny]]'' begins with Darth Vader suffering an injury while testing a prototype TIE fighter that reveals that a chip was placed on him years ago that deliberately handicapped his ability to heal after the attack that forced him to be placed in his life support suit (in this continuity Anakin's fight with Obi-Wan did ''not'' cost him his remaining limbs). Faced with this evidence of the Emperor's brutal treatment of the man meant to be his closest subject, the majority of the crew of Vader's Super Star Destroyer, the ''Executor'', openly defect to the Rebel Alliance while Vader departs for Tatooine to assist in rescuing Han Solo from Jabba the Hutt.
* In ''Fanfic/TheWarIsFarFromOverNow'', roughly 75% of the agents burned by Black Widow and Captain America dumping [=SHIELD's=] files online stick with Stark Industries and refuse to return to the reformed SHIELD. Their most common tactic when called is summed up as "New phone, who dis?" Some SHIELD agents get the idea and play it off as mistaking them for someone else. Others (very foolishly) try to get insistent.
* In ''Fanfic/KaraOfRokyn'', Lex Luthor tricked Parasite into working for him and then turned him into a pile of goo stuck to Superman in order to siphon off his power. As a result of it, Parasite turns against Luthor at the first available opportunity.
* ''Fanfic/BloodIsThickerThanBone'': Being abandoned and ditched by the others leads to Tayuya joining Konoha in exchange for giving information about Orochimaru's plans and bases.
* ''Fanfic/TheMasksWeWearTeenTitans'': [[VillainProtagonist John Grayson]] betrays [[TheConspiracy The Court of Owls]] after [[BigBad Samantha Vanaver]] reneges on their deal to not bring Dick into The Court of Owls, due to this and [[BedTrick rape by fraud]] cause John to betray them.
* ''Fanfic/TheLastPrayer'': Due to both Gaara wanting to demoralize Naruto and Rasa wanting the boy pumped for information Temari is engaged to the boy, with Gaara forcing Temari to insist during the Chunin Exam finals that she never loved Naruto and that he's outright unlovable. When the invasion fails miserably and Suna is forced to pay reparations towards Konoha, [[SparedByTheAdaptation Rasa]] orders Temari to convince Naruto to cancel their engagement. Temari, fed up at being "first treated as a whore then a spoiled child" and genuinely falling for Naruto, outright refuses, stating she plans to insist on going through with their marriage.
* ''Fanfic/SonOfTheSannin'': When Orochimaru decides to leave behind one of his underlings, Hebimaru, due to considering a liability to rescue him, his twin sister Hebiko takes offense. Orochimaru manages to keep her at ease for the time being by telling her that Konoha will most certainly keep him alive (for interrogation) and promising to rescue him. But, since he never intended to fulfill that promise, and once she finally sees that he's planning on discarding them like trash, Hebiko takes things into her own hands and, in order: murders Kabuto Yakushi, takes several of Orochimaru's troops with her, captures Juugo and retrieves the stolen Scroll of Seals, and then shows up at the doorsteps of the Shinobi Alliance's Headquarters, offering Juugo and the scroll as a bargaining chip for her brother's freedom (along with information about Orochimaru's whereabouts and plans).
* In ''Fanfic/ChasingDragons'', the slave revolts that the Sunset Company inspires across Essos essentially boil down to this, as the slaves take revenge for lifetimes of abuse by their masters.

* ''WesternAnimation/MyLittlePonyTheMovie2017'': In the climax, [[spoiler:the Storm King reveals that [[ILied he had no intention of restoring Tempest Shadow's broken horn]]. This, along with Twilight [[SaveTheVillain saving Tempest from being sucked into a tornado]], convinces Tempest to switch sides, even TakingTheBullet for Twilight when she's about to be [[TakenForGranite turned to stone]]]], doing so at point-blank range results in the Storm King being turned to stone along with her, and while Twilight saves Tempest, the Storm King is left to shatter into pieces.

* ''WesternAnimation/SupermanBatmanPublicEnemies'': Miss Waller is loyal to Lex Luthor right up until she realizes he's gone bat-shit crazy. Mind you, he doesn't mistreat her, he ''hits on'' her in the mistaken belief this will somehow cement her loyalty, instead of creeping her the hell out. Being high and insane is not actually that good for your charisma.
* Luthor's deeply creepy treatment of his brainwashed replacement Superman in the ''WesternAnimation/SupermanDoomsday'' movie. It's a disturbing cross of {{Abusive Parent|s}} and FoeRomanceSubtext, and his eventual "I brought you into this world, and I can take you out of it" both inspires the betrayal and gives Cloneboy the hint to look inside his own skull for a lead-wrapped Kryptonite bomb, and carve it out. Mind you, you can't say Cloney {{Heel Face Turn}}s; Lex's whole threat-inducing problem with him is how fast he's careening into KnightTemplar BewareTheSuperman territory. He just turns ''on Lex'', and then slaughters [[SendInTheClones the whole clone army]] while they're still in their pods, because there aren't going to be any evil Supermen on ''his'' watch, nuh-uh. Just a terrifying one. And while he'd killed a murderer he only ''threatened'' the old woman with the cat, and blew up the guns of cops trying to arrest him... Anyone familiar with the character of Post-Crisis Superboy, Conner Kent, finds this especially freaky since it's like his origin story gone all wrong. Well, wronger than it was to begin with.

* In ''WesternAnimation/KungFuPanda2'', the captain of Lord Shen's wolves refuses to fire a cannon that would kill his own men. [[spoiler:Lord Shen kills him immediately and fires the cannon himself.]]
* In ''WesternAnimation/TheIncredibles1'', when Mr. Incredible grabs Mirage and threatens her life, Syndrome [[FlawExploitation calls his bluff]], knowing Mr. Incredible couldn't hurt a helpless woman. While he was spot on about Mr. Incredible, he completely failed to realize that Mirage would be upset at being treated as expendable, and might admire Mr. Incredible for his concern. She [[EvenEvilHasStandards already had doubts after Syndrome ordered missiles launched at a plane with children in it]].
* ''WesternAnimation/TheEmperorsNewGroove'': Kronk, Yzma's DumbMuscle, is treated like dirt throughout the entire film without seeming to be overly bothered by it. Towards the end, after taking a moment to consult (out loud) with his [[GoodAngelBadAngel shoulder morality companions]], Yzma finally snaps and starts into a particularly vicious tirade. The clincher is [[ArsonMurderAndJaywalking claiming to have never liked his spinach puffs]].
* In ''WesternAnimation/AladdinTheReturnOfJafar'', Iago does this right at the ''start'' of the film after having been bullied by Jafar one time too many. It's not a HeelFaceTurn right at the outset, and in fact, Iago does wind up unwillingly working with Jafar again, but it provides the spark, with the kindness of Aladdin and his friends eventually providing the rest of the motive for Iago to fully change sides.

* It is implied that the mistreatment of [[spoiler: Dawn Bellwether]] in ''WesternAnimation/{{Zootopia}}'' by her boss was one of the reasons for [[spoiler:her decision to cause a city-wide panic over fear of predators so she can remain in power]].

* ''WesternAnimation/AnExtremelyGoofyMovie'': Bradley leaves his right-hand man Tank to die in the burning X games logo just so he can finish the race. Max and Goofy manage to help Tank escape and Max wins the race. Tank then turns on Bradley for betraying him and then slingshots him towards the X-Games zeppelin flying overhead.

* In ''WesternAnimation/LeroyAndStitch'', Hämsterviel is [[TooDumbToLive dumb enough]] to tell Gantu that he'll be fired as soon as he's finished locking up Lilo and Reuben. Naturally, Gantu decides that he's got nothing to lose, and releases them.

* ''WesternAnimation/ToyStory3'' sees Big Baby's HeelFaceTurn triggered by getting fed up with Lotso's abuse when Woody returns to Sunnyside with the tag from "Daisy" which Lotso tore from Big Baby when she'd forgotten them and learns Lotso lied to him, with the breaking point being Lotso smashing the tag -- and results in Big Baby tossing Lotso into a dumpster.

* At the end of ''Film/CannibalGirls'', [[spoiler:after discovering that Cliff has sold her out to [[SinisterMinister the Reverend]], Gloria beats Cliff to death with a mace.]]

* Subverted in ''Anime/MagicalGirlLyricalNanoha''. Despite all the horrific stuff Precia does to Fate, the latter is too good of a person to even consider betrayal, even after her mother basically abandons Fate as a useless and ultimately failed experiment. Although Fate does give up her {{Love Martyr}}dom and performs a HeelFaceTurn after this event, she never gives up on trying to redeem Precia until the very end.
* ''Anime/MazingerZ'': [[TheDragon Baron Ashura]] was mostly loyal to [[BigBad Dr. Hell]], who felt that [[AvertedTrope he was above of]] [[YouHaveFailedMe executing his subordinates]] but not of punishing their failures with strikes, insults or torture. Due to this sometimes he got fed up with being mistreated and mocked and he disobeyed orders or acted on his/her own (the final time was when he [[spoiler:stole the [[AirborneAircraftCarrier fortress Ghoul]] to make a kamikaze attack on the [[HomeBase Institute]]]] in order to show all, Dr. Hell and his enemies, who he was. In Gosaku Ota's alternate manga, he went a step beyond that and he decided to betray Dr. Hell and TakeOverTheWorld on his/her own because he was "sick of that crazy old man and [[CoDragons that headless idiot (Count Brocken)]] always mocking him" and he intended to give them a lesson to everyone.
* Bunbee in ''Anime/YesPrettyCure5'' does two Heel Neutral Turns when he realizes that his employers don't appreciate him, are blocking his dream of advancement, and will likely send him to his death. [[spoiler:He finally does a full HeelFaceTurn at the end.]]
** Happens again in ''Anime/SuitePrettyCure''. Bassdrum and Baritone are treated so badly by Falsetto that when they get their hands on the Cure Modules, they give them to the Cures only to let them beat up Falsetto. [[spoiler:They unfortunately got turned evil again, but they get better.]]
** Wolfrun, Akaoni, and Majorina joined the Bad End Kingdom in ''Anime/SmilePrettyCure'' because they were treated badly due to their status as villains. [[spoiler:[[BecauseYouWereNicetoMe When they are finally given some kindness from Cure Happy]], they pull a HeelFaceTurn.]]

* ''Anime/NowAndThenHereAndThere''. Hamdo's not really helping his own case by continuously abusing his HyperCompetentSidekick Abelia, even after [[spoiler:the last bastion of LaResistance has been crushed]]. In the end, she stands by and watches him die without lifting a finger to help.

** In canon, [[spoiler:Karin gives up on Sasuke after he shoots a Chidori Blade through her to get to Danzo, and abandons her for being weak... [[SubvertedTrope but she goes back to faithfully working for him once she meets him afterwards]]]].

** {{Averted}} with Don Krieg's top fighter Gin. When the starving Gin came to Baratie, the other cooks refused him food since he had no money. Sanji, who himself had experienced starvation as a child, is unable to deny a starving person food and saved Gin's life. He does the same for Don Krieg, who then tries to take over the Baratie and kill everyone. But Gin is unable to finish off the man who saved him and begs Krieg to spare Sanji. Krieg views this as a betrayal, fires off a poison gas bomb, and demands Gin leave his gas mask off and die. At this point, you'd expect Gin to turn against such a horrible boss and side with Sanji. Gin does at least save Sanji from the gas, [[UndyingLoyalty but still refuses to turn against Krieg]].

* [[spoiler:Gemini]] in ''Manga/FairyTail'' cannot kill Lucy after seeing how kind she is and how much she values her spirits. [[spoiler:Gemini]]'s former master wasn't ''quite'' as bad as other examples of celestial mages, but thought nothing of inflicting non-lethal damage on her own spirits to secure victory. Even what seemed like an inanimate object refused to hit her. In the end, they all join Lucy.
* In ''Anime/CodeGeass'' R2, [[spoiler: Schneizel manages to convince the Black Knights to oust their leader, Zero, by revealing Zero's identity and the fact that he has mind-control powers, which he kept secret from them, along with other secrets of his that range from questionable to outright horrifying. Schneizel told them that Lelouch could have used his geass power to control ''them'', and they have no way of knowing for sure that he didn't - aside from Lelouch's word. He returned ''a whole year'' after abandoning them in the middle of a battle that they end up losing because of it, and while he had good reasons, he never told them any of it. From then on, he keeps doing things like bringing in special agents - Britannians - who report directly to him, who haven't earned the trust of the Black Knights; and creating missions that are a lot more sinister than what he tells them (like massacring an entire lab of seemingly innocent doctors and test subjects). Because of this, resentment against him had already been building, and by not explaining himself, he leaves quite the opening for Schneizel to come in and do exactly what he did]].
* Inverted in the ''Manga/SoulEater'' manga. [[spoiler:After spending their entire life as their mother's personal, human Guinea pig, Crona has effectively gone insane. Then their mother, Medusa, suddenly starts apologizing to them for everything she's done and even hugs them, calling them "her pride." The fact that Crona has never seen Medusa act in a way besides "abusive mother," Crona gets convinced that this is not the real Medusa, and completely butchers her. This turned out to be part of Medusa's ThanatosGambit in order to push Crona further into madness to the point they become a new Kishin.]]
* ''Manga/FullmetalAlchemist'':
** Human chimeras Heinkel and Darius join Edward after Kimblee blows up the mine shaft containing all three of them.
** Greed's original group of chimera allies joined him after being experimented on and denied their essential humanity by the Amestrian military. Greed, who treats them like his cherished friends, gets their UndyingLoyalty.
* ''Anime/FullmetalAlchemist2003'': Greed was already notably rebellious, but his treatment by [[spoiler:Dante]] and the other homunculi, including being sealed in a chamber for long periods, leads him to hate them so much he willingly tells Ed how to kill them.
* Fat Buu of ''Manga/DragonballZ'' was childish and difficult for [[EvilSorceror Babidi]] to control. Babidi eventually resorted to [[BadBoss threats of sealing Buu away]] unless he obeyed Babidi's orders. When Goku pointed out that it was shameful how Buu was allowing a much weaker being to control him with threats, Buu promptly killed Babidi and decided to build himself a house.
* In ''Anime/MobileSuitGundam0083StardustMemory'', Cima Garahau turns on the [[TheRemnant Delaz Fleet]] because [[AllOfTheOtherReindeer their members have been treating her and her fellow Marines like crap for years]]. In particular, Cima's fleet was denied permission to take refuge at the asteroid base Axis (with the story's main antagonist Anavel Gato casting the deciding vote) and were forced to spend the next four years hiding out from TheFederation and barely eking out an existence. (The fact that the Federation offered her amnesty and wads of money didn't hurt either.) It doesn't end well for her, not because of [[RewardedAsATraitorDeserves the trope one might expect here]], but because [[TheHero Kou Uraki]] didn't know a blessed word of this[[note]]and wasn't exactly on good terms with Federation leadership at this point anyhow[[/note]] and ends up slaughtering all the Marines before Cima's eyes before impaling her on the Gundam [=GP03=]'s megacannon and blasting her in half.
* In ''Animation/GuardianFairyMichel'', the final episode has Biam turned into a monster against his will. He reforms after snapping back to normal.
* In ''Manga/{{Claymore}}'' [[RebelLeader Miria]] attempts to overthrow the Organization on her own and [[TheRevolutionWillNotBeVilified without killing or seriously hurting any of her former Claymore companions still loyal to the Organization]], [[spoiler:but is eventually defeated. The other Claymores are expected to execute Miria for being a traitor but then decide to pull a DeathFakedForYou in Miria's favour and join the rebellion. This change of heart is caused by the Claymores' realization that Miria was the only one who gave any importance to their own lives, as opposed to the Organization's attitude which ranges from "WeHaveReserves" to downright "YouHaveOutlivedYourUsefulness"]].
* In ''Manga/AttackOnTitan'', several of these feature as significant events.
** The internal conflicts within the government come to a head when the announcement of an attack on Wall Rose reaches the capital. The commanders of the military begin preparing for a defensive operation, to buy time for as many people to evacuate as possible. Their efforts are interrupted by the nobles, who order that Wall Sina be immediately sealed and the residents of Wall Rose left to die. The military does '''not''' take kindly to being ordered to leave their own families to die. [[spoiler: It turns out to have been a SecretTestOfCharacter on Erwin's part, creating a false emergency to see what the government would do. Having seen that the government only cares for themselves, the military overthrows them and begins seizing their property to redistribute to the people]].
** The events of the series turn out to have been heavily shaped by one such occurrence in the past. [[spoiler: Grisha and Dina Yeager's attempts to mold their son, Zeke, into a TykeBomb led him to eventually betray LaResistance to the authorities, having caught wind of the authorities closing in and knowing that it would be the only way to avoid sharing his parents' fate. Their group was rounded up, and executed via being turned into mindless Titans. While Grisha was saved from this fate and entrusted with the Attack Titan's power, his wife was not so fortunate. Dina was transformed after promising they would find each other again. This would lead her mindless Titan to relentlessly stalk the Yeager family, leading to the deaths of Carla Yeager and Hannes when she tried to attack Eren. And as for Zeke, his actions placed him into the good graces of the Marleyan government, allowing him to grow up to become the leader of the Warriors and the bearer of the Beast Titan.]]
* Subverted in ''Manga/KaguyaSamaLoveIsWar''. Kaguya ''thinks'' Hayasaka could betray her trust because of how she treats her valet sometimes, but it's always just a misunderstanding. [[spoiler: The twist is that Hayasaka has been betraying Kaguya from the start, though she did so reluctantly and regrettably.]]
* ''Literature/{{Baccano}}'': After spending her entire life being verbally abused and made an unwilling accomplice to criminal acts by her creator Szilard Quates, [[OurHomunculiAreDifferent Ennis]] betrays him and aids in his destruction at the hands of [[TheMafia the Martillo family]] after he finally goes that step too far by ordering the deaths of two innocent people [[BecauseYouWereNiceToMe who had previously shown kindness to Ennis]]. What makes this example especially galling is that Szilard admits ''every'' homunculi he created before Ennis did the exact same thing; this guy just CANNOT stop abusing his creations, [[AesopAmnesia no matter how often it drives them into revolting against him]].

* There is an issue in ''ComicBook/XWingRogueSquadron'' involving Sixtus, an elite member of Imperial Special Intelligence. He [[CombatByChampion competed]] with the Rebels to impress someone so they would hand over a smuggler his superior wanted, and although the Rebels fought valiantly, Sixtus won. But, while they were competing, his superior went behind Sixtus's back, stole the smuggler, and lifted off, [[ShaggyDogStory abandoning the trooper and thirteen of his companions on Ryloth]]. Ryloth's laws mean that if they can't get transport, they get sold into slavery. So when the Rebels took them out for a drink and offered a chance to get revenge on that superior, they accepted. They didn't become Rebels themselves right away, but from the novel ''[[Literature/XWingSeries The Bacta War]]'', we know that they came around eventually.
* Happens in ''ComicBook/SquadronSupreme''; when Hyperion's EvilTwin falls in love with Power Princess, he betrays [[TheChessmaster Master Menace]].
* ''ComicBook/XMen'':
** A proxy example in the case of ComicBook/{{X 23}}: At first, Dr. Sarah Kinney was firmly ForScience in the creation of the OppositeSexClone of Wolverine, but as her immediate superior, Xander Rice's, abuse of the girl mounted (highlights: constant physical and emotional torture, placing her in the care of a psychopathic handler, exposing her to lethal doses of radiation at the age of ''seven'' to forcibly activate her HealingFactor, and ''denying'' her anesthesia ''at the same age'' during the surgery to rip out her claws one by one to bond them with adamantium) combined with the project lead's apathy (if not complicity) in the abuse, she grows increasingly disillusioned with the project and is finally driven to turn X loose on the installation and escape. Considering X herself spent ''ten minutes'' beating Rice to death '''''with her bare hands''''', [[ItsPersonal it was just a tiny bit personal]] for ''her'', as well.
** ''ComicBook/{{Magneto}}'': As a BadBoss, one shouldn't be surprised that the majority of times his underlings betray him it is motivated by abuse. The king of mistreatment-induced betrayals where Magneto is concerned is his long-time sycophant the Toad, who Mags used to, in Toad's own words, "[[http://i.imgur.com/8n4h2Vj.jpg Insult me, hit me, order me around like a slave]]". Unsurprisingly Toad eventually reached a breaking point and more than once turned on Magneto, though tragically his borderline abused housewife mentality leads him to just keep returning to Mags's side. Quicksilver and the Scarlet Witch, who also endured Magneto at his worst, left his side to join the Avengers and never looked back.
* ''ComicBook/SecretWars2015'': For eight years since the Final Incursion, ComicBook/DoctorDoom locked away the Molecule Man within his realm within Battleworld, rarely visiting him and, when he did, never fed him. When the Peter Parker and Miles Morales Spider-Men show up, Miles gives the Molecule Man a hamburger he had tucked away. During the FinalBattle between Doom and Reed Richards, Doom admits that, yes, [[AlwaysSomeoneBetter Reed would have done much better in his shoes]] and just tries to outright kill him. Pleased with hearing these words, the Molecule Man gives Reed Doom's powers, allowing him to do just that. [[spoiler:And as extra thanks, the Molecule Man brought Miles and his friends and family to the mainstream Marvel Universe, resurrecting his mom in the process.]]
* In ''ComicBook/TheTechnopriests'', Panepha spent years mistreating her daughter Onyx because the girl's father was Ulritch the Red, a pirate who had raped Panepha. This comes back to bite her in the ass when she offers Onyx to a mercenary in exchange for aid in tracking down Ulritch for revenge; the merc realizes that Ulritch will pay quite handsomely for the return of his daughter and betrays Panepha. Onyx is only too happy to play along.
* In the second ''ComicBook/MissileMouse'' book "Rescue on [=Tankium3=]", King Bognarsh's assistant, who spent most of the book being treated like the king's slave, wastes no time in helping bring him down when he learns of the uprising.

* ''ComicBook/UltimateMarvel'':
** ''ComicBook/TheUltimates'': After so many times being kept prisoner, thrown as a weapon at dangerous foes, and then captured and jailed again, Hulk joined the Maker, Kang, and Quicksilver, becoming openly evil in the process.
** ''ComicBook/UltimateXMen'':
*** Magneto's abuse of the twins eventually drives them to defect to the Ultimates, but even before Quicksilver robs Magneto of his helmet in the latter's first fight with the X-Men.
*** Wolverine probably wouldn't have defected Weapon X if they'd treated him with, if not kindness, at least basic professional courtesy. Instead, Weapon X treated him like a dog they liked to abuse, caging up and shooting him just for fun and such.

** ''ComicBook/RevolutionInSanMonte:'' CorruptCorporateExecutive Emil Norvell hires a band of mercenaries to take out Superman. Once they (presumably) do just that, Emil decides to stiff them out of paying and even threatens to call the police on them. The next evening, the mercenaries decide to take revenge on Norville for backstabbing them, [[SaveTheVillain forcing Superman to save his life]].
* ''ComicBook/BeastWarsUprising'':
** The Builders treated the Maximals and Predacons like crap for centuries, so naturally they turn on them.
** Also happens again in ''Derailment'', when Hot Rod is told by Ratbat to throw his troops into the meat grinder to slow the Resistance down a little. Hot Rod decides to Hell with that and leaves, taking those troops with him.
* ''ComicBook/WonderWoman'' [[ComicBook/WonderWoman1942 Vol 1]]: Eviless plays at betraying the Emperor of Saturn because of how he punishes failures, begging to be let into Reformation Island to learn to be a better person rather than be sent back to the Emperor. This is actually a ploy to try to destroy the Amazons from Reformation Island which doesn't work out.

* ''ComicBook/ImmortalHulk:'' General Fortean treats his staff, Dr. [=McGowan=] in particular, poorly, sneering at them for showing any glimpse of hesitation or empathy, while refusing to take any accountability for making them do these things. The only reason most of them put up with it is a feeling that they owe him, but eventually Dr. [=McGowan=] gets so fed up with Fortean's insanity that she seizes command of his operation from him, and lets the Hulk... do his thing.
* ''ComicBook/InjusticeGodsAmongUs'': In ''Year Five'', [[spoiler:The Flash, who was was having a serious conflict of loyalties, was considering going back in time to stop the events that led to the rise of the Regime. However, after being abandoned by his friends and loved ones, including Iris, he was convinced that the events were something the people deserved. Making this an example of MistreatmentInducedBetrayal [[BetrayalByInaction By Inaction]].]]
* ''ComicBook/GuardiansOfTheGalaxy:'' Korvac was initially a willing convert to the Brotherhood of the Badoon, until one day when he passed out from overwork, and the Badoon cut off his legs and wired him up to a computer bank. Korvac turned on them after that.

* [=NPCs=] in the ''ComicStrip/KnightsOfTheDinnerTable'''s party frequently end up doing this... which leads the Knights to [[ComedicSociopathy view the mistreatment as justified]] [[CircularReasoning because the NPC ended up betraying them]].

[[AC:''Franchise/{{Bleach}}'']]
* ''[[https://www.fanfiction.net/s/12394742/8/The-Defeated The Defeated]]'': After they fail to save Rukia, both Ichigo and Orihime join Aizen out of a desire for revenge on Soul Society for torturing them and killing their friends then refusing to accept they were wrong to do so. That Aizen is willing to spare their families and remaining friends is further incentive.

[[AC:''Franchise/CodeGeass'']]
* ''Fanfic/CodeGeassThePreparedRebellion'': Clovis tells CC that his experiments on her had Charles' blessing. Needless to say, once she gets free, she immediately throws her support behind Lelouch's rebellion.

[[AC:{{Crossover}}]]

* ''Fanfic/IfWishesWerePonies'' (''Literature/HarryPotter'' & ''WesternAnimation/MyLittlePonyFriendshipIsMagic''): Several Muggleborns were unable to secure magical jobs due to their [[FantasticRacism muggle origins]] and retreated into the Muggle World to survive. Unfortunately, because they had no provable secondary education, they were forced to take jobs in the military. Needless to say, when Equestria makes FirstContact and reveals the existence of magic to the British muggles, most of the Muggleborns are quite eager to help the government out with their findings on the Wizarding World and their defense against them because of how they were treated. [[spoiler:When Dolores Umbridge tries to initiate a kidnapping of Ambassador Blueblood within the Prime Ministers' own office, it triggers a stasis trap that ensnares Umbridge and Fudge as the two people responsible for creating the laws that treated Muggleborns like crap are then held at both Gunpoint ''and'' Wandpoint by British Service Agents.]]
* ''Fanfic/NewStars'' (''Series/TheOrville'' & ''WesternAnimation/StarWarsTheCloneWars''): After learning that the Kaminoans put a control chip in his head (and that they likely did the same to all of the other clones), [[spoiler: Maxx decides to sever all ties to the Republic and become a Union soldier.]]
* ''[[https://www.fanfiction.net/s/11026736/1/Operation-FOSTERS Operation: FOSTERS]]'' (''WesternAnimation/CodenameKidsNextDoor'' & ''WesternAnimation/FostersHomeForImaginaryFriends''): This is the reason that Numbuh Two-Hundred-One, AKA [[spoiler:Mac]], defected from the Kids Next Door and went into hiding. Numbuh Two-Hundred-One was a prominent cadet in both melee combat and 2x4 technology of Sector IF, until his [[spoiler:[[AxCrazy sugar-induced insanity]]]] was discovered and the scientists from the Deep Sea Base captured him and experimented on him while hiding it from Two-Hundred-One's sector mates or the higher ups of the Kids Next Door. [[BrokenPedestal The treatment broke Two-Hundred-One's faith in the organization as he thought the entire KND was involved]], and after he broke free from the scientists he faked his death and returned to his hometown. However, the trope is {{Deconstructed|Trope}}, as while Numbuh One and the moon base command do sympathize with what Two-Hundred-One went through, he still ''betrayed'' the KND by faking his disappearance. Numbuh One even points out that Two-Hundred-One [[StatingTheSimpleSolution should have told his sector mates or the higher up about what the scientists did to him]].

* ''Fanfic/{{White Sheep|RWBY}}'': Downplayed. Emerald is the ButtMonkey for most of the early fic, and in particular, her boss Cinder keeps getting mad at her for things [[CosmicPlaything that are only partly her fault]]. So when Cinder abandons her after the Battle of Beacon, Emerald doesn't lose any sleep over allying with Weiss instead. Ruby later tells Cinder that Emerald would probably still be working for her if she was just a bit nicer.

* In ''Fanfic/ThePrayerWarriors'', "Battle With the Sphinx", William, a Prayer Warrior, gets captured by Carter Kane and is taken to the Egyptian god Horus's base of operations.

* [[Anime/RebuildOfEvangelion Shinji]] joins [[Franchise/MassEffect Aria]] in ''Fanfic/AlphaAndOmega'' after his older alternate self points out that everyone in NERV and WILLE treats him like shit despite proving that they can't accomplish anything without him.
-->'''WILLE Bridge Bunny:''' So you're on their side now!?\\
'''Shinji:''' Since when were any of you ever on my side?
* ''Fanfic/OnceMoreWithFeeling'': Shinji was abandoned by his father when he was four and summoned ten years later because his father needed him to pilot a HumongousMecha and fight [[{{EldritchAbomination}} alien monsters]].

* This trope is discussed in Chapter 37 of ''Fanfic/BlazBlueAlternativeRemnant''. [[Franchise/{{RWBY}} Ozpin]] tells [[Franchise/BlazBlue Rachel Alucard]] after she insults Ironwood that her constant admonishing of him could lead to his potential betrayal due to lack of mutual respect. Ozpin even reflects on past events where he was betrayed by people who felt they weren't given their proper dues.

* Near the end of ''Film/AroundTheWorldInEightyDays2004'', Inspector Fix pulls a HeelFaceTurn after having been abused by [[NonActionBigBad Lord Kelvin]] one time too many, specifically by [[DestinationDefenestration being thrown out a window]], and tells the public that Kelvin tried to stop Fogg from winning his bet in any way possible.

Not to be confused with EvenMooksHaveLovedOnes, where the minion considers betraying the boss for being cruel to their friends or relatives. Contrast KillMeNowOrForeverStayYourHand. Watch out for HeelFaceDoorSlam. Cross your fingers for RedemptionEarnsLife. Compare RebelliousRebel, where the original discovery of the villain's treachery motivates their defection. See also DefectingForLove. When the villain's words and acts draw the character, see BringThemAround. If the minion in question ends up betraying and finishing off their former boss without actually defecting to the other side, it is TheDogBitesBack. Contrast with its polar opposite, BecauseYouWereNiceToMe.

* Lawrence from ''WesternAnimation/ThePrincessAndTheFrog'' is an inversion, doing a FaceHeelTurn for being mistreated by a good guy. He is Prince Naveen's mistreated servant/valet, who initially tries to be the StraightMan and the voice of reason to his RoyalBrat master.

* In Shadow [=Dragon8685=]'s ''Fanfic/MisfiledDreams'' Jenny Jr. has already been awed by the friendliness and compassion of Ash and Emily, so what better way for her [[ManipulativeBastard Manipulative Bitch]] of a mother to keep her on the side than by verbally abusing and disowning her. Jenny Jr.'s HeelFaceTurn is probably the easiest decision ever made as a result.
* In ''Fanfic/AnEntryWithABang[=!=]'', the Buron Cavalry decide to try and get in Clancy-Earth's good graces after they find out that C-Earth has nukes and Vorax did not mention as such beforehand. Aladdin Al Azim does the same after he realises that the Earthers he faces include Muslims and that Mecca is one of Vorax's targets.

* Inverted in ''Literature/{{Animorphs}}'' during the David Trilogy: David, the team's new SixthRanger, is more or less forcibly recruited, kidnapped, and thrust into a battle he wants no part of. He tries making the best of it for a little while, but after team leader Jake threatens to [[DisproportionateRetribution kill him for breaking into a hotel room]] he has enough and goes SixthRangerTraitor on them.
** In context, though, Jake disliked David long before the "hotel room" incident. It was more like Jake snapped because of a series of minor infractions on David's part, such as when David kills a crow ''for the fun of it'' while in morph and then lying about having lost control of his morph.

* In the [[OneEpisodeWonder pilot episode]] of ''W.E.I.R.D. World,'' Dr Abby O’Reardon's subplot features her being routinely humiliated by her smarmy, gaslighting research partner Dr Mayhew, who steals the credit for her discoveries while barely doing any real work. Abby tolerates this (barely) because Mayhew has [[ChosenConceptionPartner promised to provide her with children]] as payment for their partnership... but it eventually turns out that Mayhew got a vasectomy many years ago and never had any intention of fulfilling his part of the bargain. This proves to be the final straw for Abby, who doses him with her [[FountainOfYouth youth serum]], then takes great delight in humiliating Mayhew when he turns up as a child and making it abundantly clear that she's going to be calling the shots from now on. In the finale, it's revealed that Mayhew regressed all the way to infancy and was [[RaiseHimRightThisTime adopted by Abby as her son]].
