History MoralityChain / FanWorks

* In ''FanFic/ACureForLove'' L becomes Light's Morality Chain. Even after Light [[spoiler:[[MemoryGambit regains his memories]]]] [[NobleDemon he shows more restraint as Kira]] than he did before (to the point that a fellow KnightTemplar thinks he’s gone soft) and Light even considers L to be his [[EnemyMine "partner" in destroying another enemy.]] But then when L "[[EtTuBrute betrays]]" Light [[spoiler:by suggesting he should be committed; Light snaps, [[TheUnfettered abandons any remaining moral constraints]], and essentially [[TakeOverTheWorld takes over the world]] in an afternoon]].

* In ''[[https://www.fanfiction.net/s/9919015/1/Voiceless Voiceless]]'' the Third Hokage seems to be this for Naruto. In the fourth chapter, the narration mentions how he sometimes despises Kakashi, and frequently thinks of leaving the village due to not having any other attachments.

* In ''Fanfic/IncarnationOfLegends'', Bell is this for Kojiro, who would normally simply look for opponents to amuse himself with. If not for Bell, Kojiro would have simply ignored Haruhime's plight as something that isn't his own business. But Bell's admiration of him instills in Kojiro a desire to prove himself worthy of it that even [[MagneticHero Ritsuka Fujimaru]] could not.
* ''FanFic/InnerDemons'': In a way, [[TheDragon Trixie]] serves as this to [[BigBad Queen!]][[FaceHeelTurn Twilight]], as the former's UndyingLoyalty brings out what little compassion and good is left in the latter. [[spoiler: When Trixie dies, Queen!Twilight suffers a full-blown VillainousBreakdown and shifts from an EvilOverlord to an OmnicidalManiac.]]
* An InvokedTrope in ''FanFic/{{Heir}}'' when Voldemort worries about what kind of monster he might become without [[SlashFic Severus.]]
* In the ''[[Literature/TheHungerGames Hunger Games]]'' fanfiction ''Fanfic/SomeSemblanceOfMeaning'', heroine Vale holds onto the promise she made to her younger sister that she wouldn't sacrifice her morality in the arena, whenever she considers doing anything morally reprehensible (not that such a ShrinkingViolet would probably start chopping her friends and allies to pieces, anyway, but her promise to Laurel ensures it). An even better example would be the way that Vale herself serves as a Morality Chain to [[spoiler: Obsidian]].
* In ''Fanfic/ChildrenOfTime'', Professor Moriarty tells Dr. Watson that Literature/SherlockHolmes is "drowning" without his Watson. Heartbreakingly true.
* In ''[[http://www.fanfiction.net/s/9101451/2/Kaleidoscope-of-Magic Kaleidoscope of Magic]]'' Hermione becomes the one thing keeping Harry gray-not-dark after Dumbledore and Algernon Croaker throw him into Azkaban and have him tortured to give him a superpower which only awakens in response to extreme misery.
* In ''Fanfic/IfThemsTheRules'', a TimeTravel fic where Harry raises young Tom Riddle. Tom is still a Sociopath but he behaves himself out of loyalty to Harry [[BecauseYouWereNiceToMe because Harry is the only person to ever show him kindness.]]
* In ''FanFic/DiariesOfAMadman'', Taya and Flo often act as this for Navarone, putting a damper on some of his more unethical behaviour.
* In ''[[https://www.fanfiction.net/s/7934083/1/He-Is-Not-One-of-Us He Is Not One of Us]]'' Snape finds out that Harry is secretly studying the Dark Arts and advises him to keep some humanity in order to avoid their seductive aspects and Harry replies (referring to Hermione) "She's outside the door."
* In ''[[https://www.fanfiction.net/s/5725656/1/Fates_Favourite Fate's Favourite,]]'' Harry serves as this for teenage Tom Riddle, who considers Harry to be his equal and his best friend (despite having that pesky moral code) and does not want to make him too upset.
* In ''FanFic/MegaManReawakened'', Robert was this to Tron when he was human. When she finds out he's still alive, she turns good. Later it's reversed, with Tron helping to keep him on the straight and narrow.
* Molly Weasley is this to Harry in the one-shot ''[[https://www.fanfiction.net/s/8788731/1/Harry-Potter-and-the-things-that-could-have-happened After The Final Battle]]''. Harry easily admits to himself the only reason he doesn't kill Ron is because he knows it would devastate her and she's the only adult who's ever acted like a parent for him. Especially after seeing her boggart (which shows a person's greatest fears) is her family dead, which includes Harry.
* In a series of stories written by ''[[https://www.fanfiction.net/u/1640403/WithoutHesitation WithoutHesitation]]'', Film/{{Beetlejuice}} is a complete monster who frequently and indiscriminately commits acts of extreme violence... except when Lydia is around, and only because he doesn't want her to view him in a negative light. Ironically, later in the series it's implied that his relationship with Lydia ultimately resulted in Beetlejuice murdering many, many ''more'' people than he would have if he'd never met her, all due to his aggressively possessive and protective behavior.
* Zigzagged in ''Fanfic/{{Cultstuck}}''. Karkat is Gamzee's moirail, and Gamzee sobers up, [[spoiler:which makes him evil]], so he can protect Karkat effectively. During Gamzee's POV chapters, his love for Karkat is basically the only thing keeping him coherent. The creepiness of this is ''[[NightmareFuel not]]'' ignored.
* Inverted in the ''Batman'' fanfic ''[[https://www.fanfiction.net/s/9503887/1/Macushla Macushla]]'', where Stephanie Brown, due to a [[ItMakesSenseInContext long series of events]], becomes Damian's bodyguard and caretaker/MoralityPet. After Talia al Ghul [[KickTheDog has Stephanie killed]] [[spoiler:or at least, that's what she tells Damian]], Damian joins the Batclan to honor her memory.
* In ''[[https://www.fanfiction.net/s/10645463/13/Hail-Odysseus Hail Odysseus]]'' James Potter's shade heavily implies that a Slytherin Ginny Weasley serves this function for Harry.
* In ''[[https://www.fanfiction.net/s/11155989/6/Serenity Serenity]]'' Tom Riddle snapped and became an OmnicidalManiac after unintentionally killing Myrtle with the basilisk.
* In ''[[Fanfic/{{Cinderjuice}} The Bug Princess]]'', Lady Delphine observes that WesternAnimation/{{Beetlejuice}} is unusually benign for a poltergeist. He admits that Lydia "[[KidWithTheLeash holds the leash]]" and that it's for love of her that he's so well-behaved, though he adds that the longer they're apart, "the more mindless and chaotic" he's likely to be.
* In ''[[https://www.fanfiction.net/s/11567521/4/Is-Your-Great-Aunt-an-AI Is Your Great-Aunt an AI?]]'' Franchise/HarryPotter is the one thing which enables [[VideoGame/{{Portal}} GLaDOS]] to preserve a sliver of humanity and morals.
* Donquixote Rocinante considers his sister-in-law Evelyn Potter and nephew Atticus as this to his brother Doflamingo in ''[[https://www.fanfiction.net/s/12113081/1/The-Emerald-Rose The Emerald Rose]]''. Doflamingo is still a sociopathic grade-A jerkass, but Rocinante really doesn't want to imagine how he would be without his wife's humanizing influence.
* In ''[[https://www.fanfiction.net/s/4754974/12/Forgotten Forgotten]]'', Dracula is perfectly happy to let live humanity as long as his beloved wife is besides him. His servants are not happy about it and decide to kill Mina Hakuba - the latest reincarnation - and destroy her soul to ensure she would be unable to redeem Dracula again. Soma disagrees with it. Quite violently.
** Alucard later begs Mina to teach Soma how to live without her, pointing how she could die from illness or old age and ''still'' Soma would fall into the darkness because of it. She promises she will.
* Itachi becomes this to Sasuke in ''Fanfic/SonOfTheSannin'', always working hard to keep him from losing his path.
* In ''Fanfic/AdviceAndTrust'', Rei is the one thing keeping Kaworu from giving into his Angelic instincts and becoming [[SuperpoweredEvilSide Tabris]]. [[spoiler:When she dies in a HeroicSacrifice against Armisael, it's only thanks to a combination of his knowledge that she usually gets better in other timelines and a well timed pep talk from Mrs Horaki that keeps him from trying to start Third Impact right then and there.]]
* In the ''WesternAnimation/MiraculousLadybug'' fic ''[[https://archiveofourown.org/works/14792883/chapters/34223034 Fox Rain]]'' Trixx acts as this to Lila, keeping her from her canonical descent into villainy by giving her the courage to not become a shut-in and fester on her anger and later [[spoiler:warning her she was being manipulated by [[BigBad Papillon]] into mistrusting all her friends]].
* In ''[[https://www.fanfiction.net/s/12986165/5/A-Monster-s-Marriage A Monster's Marriage]]'', Jaune is married to [[BigBad Cinder Fall]]. His genuine kindness actually rubs off on Cinder, making her ''slightly'' less of a controlling bitch. Even Mercury and Emerald find themselves feeling like normal people when interacting with Jaune.
* In ''Fanfic/GazDreamsOfGenie'', Dib turns out to be this for Professor Membrane. In the new reality Gaz creates by accidentally [[RetGone wishing Dib was never born]], the Professor's disappointment at his only child being an apathetic video game junkie causes him to give up on humanity and become TheQuisling to the Irkens after they conquer Earth, saying with comedic specificity that if he had a child like Dib he wouldn't have.

* ''Fanfic/JauneArcLordOfHunger'': Pyrrha becomes one for Jaune as he is gradually corrupted by the Dark Side. Jaune's attachment to Pyrrha and desire to do right by her ends up being the only thing that keeps him from undergoing a full FaceHeelTurn and embracing his worst impulses.
* In [=Starfox5=]'s Franchise/HarryPotter fanfic [[https://www.fanfiction.net/s/13045929/1/Reformed-Returned-and-Really-Trying "Reformed, Returned, and Really Trying"]], Gellert Grindelwald tries to stay on the side of good, but his idea of ethics is largely "things Albus said to do."
-->Unfortunately, none of the remains had been in a condition to be repurposed as [[UndeadIndex Inferi]] - no, wait, Albus had been quite clear about how that wasn't acceptable.

* In ''Fanfic/FateStarryNight'', Jack would have gone on a killing spree in Fuyuki if not for her fear of being scolded by Ritsuka, instead venting her impulses on the mud copies of him that have been sprouting up around the city.
* In ''Transformers Meta ItsPersonal'' Hound inwardly ''directly states'' that Bumblebee is this to Grimlock while he is contemplating their friendship.
* ''Fanfic/ACrownOfStars'':
** In chapter 52 Shinji realized he was just like his father and he would also burn the world for the woman he loves. So that he asked Asuka keeping him from becoming a monster.
** Shortly before Asuka had wished punishing a bloody dictator and rapist with extreme prejudice, but she held back because she thought that Shinji -who hates hurting people and killing- would have a trouble with punishing him too severely.
* Fluttershy becomes this for Rainbow Dash in ''Fanfic/RainbowDoubleDashsLunaverse'', as Rainbow Dash in this continuity never became the Element of Loyalty, thus never forming the TrueCompanions like in the main story. This also deconstructs this trope in that with just a MoralityChain and no one else, she is unable to extend that sympathy to other people or really relate to them.

* In ''[[https://www.fanfiction.net/s/9919015/1/Voiceless Voiceless]]'' the Third Hokage seems to be this for Naruto. In chapter 4 the narrator mentioned how he sometimes hated his trainer, Kakashi, and often thought about leaving the village because he didn't have many other attachments.
* In ''FanFic/ACureForLove'' [[Manga/DeathNote L becomes Light's]] Morality Chain. Even after Light [[spoiler: [[MemoryGambit regains his memories]]]] [[NobleDemon he shows more restraint as Kira]] than he did before (to the point that a fellow KnightTemplar thinks he’s gone soft) and Light even considers L to be his [[EnemyMine "partner" in destroying another enemy.]] But then when L "[[EtTuBrute betrays]]" Light [[spoiler: by suggesting he should be committed; Light snaps, [[TheUnfettered abandons any remaining moral constraints]], and essentially [[TakeOverTheWorld takes over the world]] in an afternoon.]]
* In ''Fanfic/AllYouNeedIsLove'' [[Manga/DeathNote Naomi Misora]] realizes, to her horror, that she's the Morality Chain so she sticks around [[WithFriendsLikeThese Light]] even while knowing he's a [[ManipulativeBastard manipulative]], [[{{Narcissist}} narcissistic]], mass-murderer because she knows he could be ''so much worse.''
* ''Fanfic/ChildOfTheStorm'' has Carol as Harry's in the sequel, after a horrific TraumaCongaLine at the hands of the Red Room which led to him briefly becoming [[spoiler: the Dark Phoenix]]. While there are a lot of candidates for this role, and some initially know him better than she does, she has the advantage of an accidentally created PsychicLink with Harry. This means that she's a very good judge of [[MasterActor his]] [[ConsummateLiar actual]] mood and tends to keep him grounded - either through kindness or BrutalHonesty. As he recovers, this role becomes less necessary (though [[spoiler: her death is explicitly what would set him off again]]), but the likes of Peter Wisdom still see her as something like the KidWithTheLeash.
** Unusually, despite their long-running romantic tension, LoveRedeems is firmly dismissed. As both agree, they both have far too many issues to date anyone - at best, it would be a horribly co-dependent relationship, with Harry using Carol as a LivingEmotionalCrutch. They instead [[AnchoredShip opt to leave the door open]] for something when they're both (particularly Harry) more stable. [[spoiler: Lo and behold, in chapter 46 of the sequel, after Harry definitively proves his ability to get through not one, but two major crises while comprehensively resisting the temptation to use his inner Phoenix, and Carol's got over most of her trust issues, they get a RelationshipUpgrade.]]
* In the ''[[WesternAnimation/AvatarTheLastAirbender Avatar]]'' [[Fanfic/MoralityChainAvatarTheLastAirbender fanfic by the same name as this trope]], Zuko (and to some extent Ursa) is a morality chain for Azula. Striving to earn her mother's affection, she goes along with her promise to watch over Zuko. She is still a manipulative psychopath with little concept on base emotions like [[EvilCannotComprehendGood love]] and still out to capture the Avatar, but she shows genuine care and concern for not only her brother but her friends Ty Lee and Mai as well. You cannot help but to root for her in some scenes.

* ''Fanfic/MoralityChainAvatarTheLastAirbender'': As should probably be expected from the title. Azula actually cares deeply for Zuko, which indirectly taught her enough empathy to maintain a cordial relationship with her uncle and real friendships with Mai and Ty Lee, instead of just treating them as servants. She is still evil for the vast majority of the fic, but tends to engage more in PragmaticVillainy, uses the carrot-and-stick approach to motivation instead of just constant threats, and several times does things for no reason than because it would make her family or friends happy. Even after they join Team Avatar, though, it takes her a long time to be anything like ''good''.

You cannot help but to root for her in some scenes.

* Another ''Franchise/DeathNote'' fanfic, ''Fanfic/AndTheStoryContinues'', poses [[OriginalCharacter Erin]] as this for {{Shinigami}} Umbra. He only pays much mind to what she says, and she's basically the reason he eventually defects to Near's side rather than continue to work with [[spoiler:the new Kiras Kiyomi and Teru]] and do who knows what afterwards. [[spoiler:Umbra may be drawn to her because of the past relationship they'd developed back when he used to be human.]]

* In ''Fanfic/GazDreamsOfGenie'', Dib turns out to be this for Professor Membrane. In the new reality Gaz creates by accidentally [[RetGone wishing Dib was never born]], the Professor's disappointment at his only child being an apathetic video game junkie causes him to give on humanity and become TheQuisling to the Irkens after they conquer Earth, saying with comedic specificity that if he had a child like Dib he wouldn't have.

* ''Fanfic/JauneArcLordOfHunger'': Pyrrha becomes one for Jaune as he is gradually corrupted by the Dark Side. After falling to the Dark Side and [[TookALevelInJerkass taking a huge level in jerkassery]], Jaune's attachment to Pyrrha and desire to do right by her ends up being the only thing that keeps him from undergoing a full FaceHeelTurn.

* Fluttershy becomes this for Rainbow Dash in ''FanFic/RainbowDoubleDashsLunaverse'', as Rainbow Dash in this continuity never became the Element of Loyalty, thus never forming the TrueCompanions like in the main story. This also deconstructs this trope in that with just a MoralityChain and no one else, she is unable to extend that sympathy to other people or really relate to them.

* In [[https://www.fanfiction.net/s/12986165/5/A-Monster-s-Marriage A Monster's Marriage]], Jaune is married to [[BigBad Cinder Fall]]. His genuine kindness actually rubs off on Cinder, making her ''slightly'' less of a controlling bitch. Even Mercury and Emerald find themselves feeling like normal people when interacting with Jaune.

* ''Fanfic/ChildOfTheStorm'' has Harry end up with Carol as this in the sequel, after a horrific TraumaCongaLine at the hands of the Red Room which led to [[spoiler: his briefly becoming the Dark Phoenix]]. While there are a lot of candidates for this role, and some initially know him better than she does, she has the advantage of an accidentally created PsychicLink with Harry. This means that she's a very good judge of [[MasterActor his]] [[ConsummateLiar actual]] mood and keep him grounded - either through kindness or BrutalHonesty.

* ''Fanfic/ChildOfTheStorm'' has Harry end up with Carol as this in the sequel, after ''Forever Red'', a horrific TraumaCongaLine at the hands of the Red Room which led to [[spoiler: his briefly becoming the Dark Phoenix]], which remains as a kind of SuperpoweredEvilSide. While he has a number of friends and loved ones who might also play this role (and as she freely admits, in most scenarios, they know him better than she does - though the number of scenarios decreases rapidly as time goes on), Carol has the advantage of a two-way PsychicLink with Harry, which he accidentally created in the first chapter of the sequel as a side-effect of some clumsy, consensual psychic surgery to deal with nightmares. This means that she's a very good judge of his moods and what he's [[MasterActor really]] [[ConsummateLiar thinking,]] and can therefore spot the warning signs, and keep him grounded - either through getting him to open up, or by employing BrutalHonesty. As he recovers, this role becomes less necessary - though her dying is explicitly stated as the one circumstance where Harry would even ''consider'' unleashing [[spoiler: the Dark Phoenix]].
** Unusually, despite their long-running romantic tension and the two of them admitting their feelings for each other, the idea of dating because LoveRedeems is firmly dismissed. As both agree, they both have far too many issues to date at this point (WordOfGod points out that at best, it would be a horribly co-dependent relationship, with Harry using Carol as a LivingEmotionalCrutch).

* In ''[[https://www.fanfiction.net/s/11567521/4/Is-Your-Great-Aunt-an-AI Is Your Great-Aunt an AI?]]'' HarryPotter is the one thing which enables [[VideoGame/{{Portal}} GLaDOS]] to preserve a sliver of humanity and morals.
