->''"Don't ask me to leave you and turn back. I will go where you go and live where you live. Your people will be my people, and your God will be my God. Where you die I will die, and there I will be buried."''
-->-- '''[[Literature/BookOfRuth Ruth]]''', Literature/TheBible

A character characterized by his or her loyalty. Can be a trait of both heroes and villains. Most of them are supporting characters, intended as sympathetic. Indeed, if used on a [[EvilVirtues villain]], it can sometimes be used to [[MoralityPet flesh him out and give him redeeming qualities]]. Alternatively, it can be negatively portrayed as a threat to conscience.

When given to a main character or one in an authority position, expect it to manifest itself in protective instinct: as a PapaWolf or TheCaretaker or someone who is AFatherToHisMen. When given to a {{Sidekick}}, expect it to be an unselfish [[SubordinateExcuse willingness to support]] the main character. It can also be given to friends who, despite their differences, are genuinely fond of the other, and bonus points if it works both ways.

Should the object of this loyalty die, expect generous helpings of DueToTheDead as the loyal one works to honor the fallen one's memory.

See also: MyCountryRightOrWrong, MyMasterRightOrWrong, ThickerThanWater, IWillWaitForYou, IAmSpartacus. An ActOfTrueLove will often be used to prove how loyal one character is to another, by having them perform a great sacrifice to show that they'll put someone else's needs before their own.

Similar to but not to be confused with BlindObedience, where a character follows unquestioningly believing their liege to be infallible. A loyal character isn't necessarily defined as a perpetual YesMan, and may know when to [[TheConsigliere defy or contradict the subject of their devotion]], especially if it's as much for ''[[ToughLove their]]'' well being as their own. At times this trope might actually come at the expense of those they follow, since they will generally not obey an order that comes at their expense or abandonment.

Characters that may exhibit this trope: BattleButler, TheDragon, HappinessInSlavery, TheRenfield, TheIgor, LoyalAnimalCompanion, RobotBuddy, SarcasticDevotee, PsychoSupporter, ExtremeDoormat, WorthyOpponent, TheChampion, {{Sidekick}}, YesMan, SycophanticServant and most of the characters on the SubmissiveBadass index.


[[folder:Anime and Manga]]
* ''LightNovel/Overlord2012'':
** The Floor Guardians toward Momonga. It makes sense, considering they were originally [[NonPlayerCharacter NPCs]] created by Momonga and his fellow guild members, having their unwavering loyalty to their creators (or "Divine Beings," as they so lovingly refer to them) hardcoded into their personalities. Literally the only way to force one of them to turn against Momonga is to use a [[BrainwashedAndCrazy brainwashing]] World Class item on them, an item so powerful that a person could literally rewrite the original game's rules (well, ask the devs to do so) if they possessed one.
** However, it should be noted that each of the Floor Guardians is infinitely more loyal to the guild member who created them than Momonga himself, and would instantly turn on him if their creator requested it. Momonga doesn't mind, as he sees it as proof of how much the [=NPCs=] care for his friends and their legacies just as much as he does. The sole exception is [[{{Yandere}} Albedo]], due to Momonga jokingly rewriting her code to be deeply in love with him moments before being transported to the New World, and who is [[spoiler:currently putting together a team of Guardians to hunt down and kill the other Supreme Beings except her own creator]] who they see as having betrayed them [[spoiler:because they'd stopped playing the game, mostly due to real life getting in the way, and were never aware that their creations would become sentient]], but Albedo's too far gone to understand that.
** It runs both ways: Momonga's offline life was so crappy that the game was his only joy, spending large amounts of his income on it and managing the guild, so his guildmates' NPCs are the closest things he has to being with his friends again. On hearing Evileye nearly killed [[spoiler:Entoma]], he very nearly killed Evileye on the spot if she hadn't been necessary for the plan as a witness.
** Their loyalty is such that Momonga finds it near impossible to get constructive criticism from them, because they're ready to off themselves and each other at the slightest hint of disrespect towards their master, even when said master is asking for them to have different opinions.
** Demiurge is a scheming mastermind who puts together complex plans to take over the world... all because he misinterpreted an offhand comment by Momonga about how it might be interesting to do so as an official order from the Supreme Being. Despite everything about him screaming "eventual traitor", he also genuinely views Momonga as his superior as an EvilGenius (where he expected to bring the Empire to heel only after long attrition and horrendous casualties on both sides, [[spoiler:Momonga convinces the Emperor to submit entirely by accident]] in a few hours just by showing up), and considers every time Momonga congratulates him on his plans working to be praise from Caesar.
* ''Anime/BloodPlus'': Chevaliers are biologically wired to be absolutely dutiful and devoted to the Queen who turned them [[spoiler:though it is possible to overcome this, as shown by Diva's Chevalier, Solomon, when he falls in love with the rival Queen, Saya.]]
** Haji in particular is characterized almost entirely by his unswerving loyalty to Saya. In something of a deconstruction, Haji's devotion makes him reluctant to speak out when Saya makes decisions that might be bad for her; he even promises [[spoiler:to kill her once she succeeds in killing Diva]], and it takes being confronted and berated by Saya's brother Kai before Haji will admit that he would ''much'' rather not go through with it.
* Byakuya from ''Manga/{{Inuyasha}}'' is the only one of Naraku's detachments shown to be completely loyal to him, and he's also the only character in the entire series who doesn't completely despise Naraku and does not betray him.
* ''Anime/KillLaKill''
** [[FiveManBand The Elite Four]] are all unshakably loyal to Satsuki, each one ready to give his or her life for her at a moment's notice (''especially'' Gamagoori).
** Senketsu is completely devoted to protecting Ryuko (earning him the FanNickname "Broketsu").
** Nui is undoubtedly loyal to Ragyo, by the finale she proves this by [[spoiler:killing herself when Ragyo ordered her to.]]
* In [[SuperRobot super robot anime]], ThePowerOfFriendship is pretty much one of the main themes, and there are quite a lot of episodes where people turn their backs on the protagonist, but there will ALWAYS be at least one character who will never abandon him.
* The defining trait of pretty much all Clansmen in ''Anime/{{K}}''. This relationship between Kings and their Clans is a central theme of the series.
** Kuroh Yatogami, who enters the story on a mission from his late master, and [[spoiler: finding a new King to give his loyalty to]]. His faith in his King gives him strength. "I wield my sword only to protect him. My sword will open up the path and lead my to my King!"
** Misaki Yata, third-in-command of the Red Clan, idolizes the Red King [[spoiler: - both Mikoto and his successor.]]
** And most notably, Saruhiko Fushimi, former Red Clansman and third-in-command of the Blue Clan. He felt none of this towards the Red King Mikoto, and scoffed at HOMRA's awe and loyalty towards him. When he left and joined Scepter 4, he didn't want to let himself feel this way towards the Blue King. It wasn't until [[spoiler: Misaki, his friend-turned-enemy-turned-friend again, and the only HOMRA member not to realize he wouldn't stay with them, realizes it and tells him, "You're not a traitor - if you would go this far for the Blue King, that means he was your King all along!"]], that he realizes he feels this.
* ''Anime/CodeGeass'':
** Out of loyalty to [[spoiler:Lelouch]], Jeremiah Gottwald [[RammingAlwaysWorks suicidally charges]] an enemy's [[HumongousMecha giant robot]] with his own giant robot, [[SelfDestructMechanism ''detonates'']] his giant robot, [[OutRunTheFireBall leaps out of his robot's cockpit seconds before the explosion]] and [[CrowningMomentOfAwesome holds the enemy pilot captive at swordpoint]]. The dude even takes the [[InsultOfEndearment shameful and insulting nickname]] that [[spoiler:Lelouch]] originally gave him and wears it as a ''[[AppropriatedAppellation badge of honor]]'' after his [[spoiler: HeelFaceTurn]]. Also, he spiels one of the [[LargeHam hammiest]] one-liners of this trope ''ever''.
--->'''Jeremiah:''' '''''[[PreAssKickingOneLiner TASTE THE]] [[LargeHam STORM]] OF [[EmphasizeEverything MY LOYALTY]]!!!'''''
** To top it off, Jeremiah's loyalty to [[spoiler:Lelouch]] comes from his loyalty to [[spoiler:Lelouch's mother Marianne]]. Now that's truly undying. [[spoiler: He even stuck with Lelouch all the way through the Zero Requiem; he's so loyal that if Lelouch wants to pull a HeroicSacrifice ZeroApprovalGambit ThanatosGambit like that, ''he will support him''.]]
** Gilbert Guilford is the same towards his liege Cornelia. He's just ''much'' quieter about it. He's [[EveryoneCanSeeIt obvious]] enough that [[ManipulativeBastard Lelouch]] can take advantage of it though.
** Kallen Kōzuki/Stadtfeld also holds this toward Lelouch, such that the latter has to seriously go out of his way to have her stand against him during Zero Requiem, by [[BreakHisHeartToSaveHim breaking her heart]] and forcing her to choose to [[LovedINotHonorMore stand by her ideals and fight against him instead of staying by his side]]. Kallen confesses in her character poem that if Lelouch had given any indication that he loved her, even if it had been a lie, she would have followed him to hell. She then goes on to say that although she knows Lelouch had purposely kept quiet for her sake because he had known that she would have chosen to stay with him till the end, she did not fall in love with him because of this [[ItsNotYouItsMyEnemies kindness]] (Implying that she wishes he would have been honest with her, and let her make her own decisions, instead of keeping her in the dark to protect her).
** {{Meido}} Sayoko Shinozaki is totally devoted to the Lamperouge siblings, to the point where [[spoiler:she's the only Black Knight who remains loyal to Lelouch for the entire show]].
* Patrick Colasour embodies this for his superior officer, Kati Mannequin in ''[[Anime/MobileSuitGundam00 Gundam 00]]''. The reason is love. The undying loyalty is his cockroach like tendency to survive any dangerous NoOneCouldSurviveThat situation, especially on her orders. Eventually, it pays off big time [[spoiler:with him [[ThePowerOfLove winning her hand in marriage]]]].
* Agnes to Henrietta in ''LightNovel/TheFamiliarOfZero''.
* Haku from ''Manga/{{Naruto}}'' to Zabuza, who rescued him while he was an orphan struggling to survive in the city.
** Kimimaro to Orochimaru [[spoiler:even after being resurrected.]]
** Konan to Nagato.
** Also Kisame Hoshigaki to Tobi.
** Even after death, Uchiha Itachi is still loyal to Konoha.
** Yashamaru to Hidden Sand Village. As a shinobi, he served as a member of Suna's black ops and as the right hand of the Fourth Kazekage, Gaara's father despite hating him for sealing Shukaku into his pregnant older sister and Gaara's mother. It was because of this loyalty that Yashamaru willingly went through the assassination attempt to test Gaara despite legitimately caring for him and objecting to them.
* ''LightNovel/FateZero'' has an example with Alexander The Great's [[MentalWorld Reality Marble]], Ionioi Hetaroi, which summons the BadassArmy that he controlled in his life. It's ''literal'' undying loyalty. Later on, [[spoiler:Waver Velvet]] proudly shouts that he is not Alexander's [[spoiler:master]], he is his follower. [[spoiler:''[[ItsAllAboutMe Gilgamesh]]'']] [[CrowningMomentOfAwesome spares him because of this]].
* ''Manga/KatekyoHitmanReborn'': Gokudera towards Tsuna is this trope, completely and totally. Heck, his whole character song seems to be a tribute to his undying loyalty towards Tsuna.
** Arguably, Squalo qualifies as this for Xanxus. Not only did he wait 8 years for Xanxus' return, but he grew out his hair and puts up with crap that would make a BastardBoyfriend seem like a pleasant alternative.
* Literally the case of Koinosuke Odago in ''Anime/JubeiChan'', became undead to follow his master's directive through sheer force of will for 300 years.
* ''Manga/MahouSenseiNegima'' has Setsuna [[BodyGuardCrush acting]] [[RomanticTwoGirlFriendship like this]] [[SchoolgirlLesbians toward]] Konoka.
** Fate's female minions act like this toward him as well. [[spoiler:He took them all in as children after their parents were killed in the war]].
* ''Franchise/LyricalNanoha''
** The {{Familiar}}s and [[RidiculouslyHumanRobots Wolkenritter]]. If it's for the sake of their master, the rightness or wrongness of an act doesn't matter, and if it will benefit or save their master, they will gladly give up their lives, powers, and/or freedom.
** In the Wolkenritter's case, this overlaps with MyMasterRightOrWrong, as it was implied that some of the masters of the Book of Darkness were evil. This makes itself prominent in ''[[Anime/MagicalGirlLyricalNanohaAs A's]]'', where Signum stated they would gladly throw their honor away if it means saving their mistress as well as during ''[[Anime/MagicalGirlLyricalNanohaStrikers StrikerS]]'' where Vita stated that she did not have any plans of outliving Hayate. It's also literally undying, since the first thing they said after [[spoiler: being resurrected]] was a BadassCreed about their loyalty to Hayate.
** Fate Testarossa as well, initially toward Precia, then Nanoha.
** Several of the Numbers have this towards each other, most of them going so far as to declare that where one goes, they'll follow. Case in point: Sette to Tre.
* ''Manga/JoJosBizarreAdventure:''
** Robert E.O. Speedwagon is extremely loyal to Jonathan Joestar via DefeatMeansFriendship, combined with his selfless rescue of him from a burning building/Vampire attack. This loyalty would extend to the entire Joestar family, even more than half a century later.
** On the villain side, we have Vanilla Ice. How loyal is he? He ''cuts off his own head when Dio says he needs blood.'' Dio actually turns Ice into a vampire in thanks for this. When he fights Iggy and Polneraff, he delivers a NoHoldsBarredBeatdown to Iggy just for making him destroy an ''effigy'' of Dio.
%% Bjorn to Askeladd in ''Manga/VinlandSaga''.
* ''Manga/OnePiece:''
** Each of the Straw Hats are fiercely loyal to their [[TheCaptain captain, Luffy]], ready to risk their lives for him as soon as he gives the word. At one point, when Bartholomew Kuma wanted to kill Luffy, both Zoro and Sanji, without a moment of hesitation, [[HeroicSacrifice offered their lives]] instead. This loyalty goes both ways. Luffy is just as willing to die for his crew and, ultimately, when he was at his very lowest, [[WorthLivingFor they were the only reason he bothered to keep on living]].
** Donquixote Doflamingo's crew have absolute loyalty and faith in Doflamingo, even to the point of death. Doflamingo himself seems to care for his crew (as long as they don't betray him), but that does not stop him from letting them kill themselves for him.
** One of his minions in particular, Bellamy, serves as a deconstruction; even back when he was little more than a thug with a devil fruit, the one redeeming quality he's always had is his loyalty. Unfortunately, his loyalty is ''wasted'' on Doflamingo, a man completely undeserving of it, who goes out of his way to spit on that loyalty whenever he can. Even as it becomes clearer to Bellamy that he admired the wrong guy (which he later fully admits to Luffy), his principles and his pride refuse to allow him to turn his back on the idol he has been devoted to for so long.
** Also, Daz Bonez towards Crocodile. It's probably why out of all of Baroque Works, it was him Crocodile liked the most and why Crocodile made it a point to free him during the escape from Impel Down.
** Trafalgar Law definitely has this for Corazon, [[spoiler:a.k.a. Donquixote Rocinante]]. He outright states that Corazon is his most cherished person, that he only decided to continue living to fulfill Corazon's wishes, and that he would gladly destroy the entire world as long as it was for Corazon's sake. It is to the point that he dedicates half his life to murdering Doflamingo in order to avenge him, and it is this RoaringRampageOfRevenge that culminates in the Dressrosa Arc.
** During the Dressrosa arc, several characters banded together to fight alongisde Luffy against the Donquixote Family after having come to admire Luffy in the gladiator's tournament many of them participated in and after Usopp saved them from being transformed into LivingToys and made slaves for Doflamingo. At the arc's conclusion, all but a few of them swear formal fealty to Luffy. This is done over Luffy's own objection, as Luffy doesn't want to be some bigshot leader nor be responsible for tying them down. They simply reply that if being free to do as you please is the most important thing to Luffy, then they'll just do what ''they'' want and make their oath.
** The entire Mink tribe were willing to all be tortured and killed, and let their entire civilization be destroyed because they wouldn't [[spoiler:give up one of their allies to an enemy ([[UpToEleven said ally had to be physically chained up so he wouldn't be able to give himself up once he realized something was wrong]])]].
* ''Anime/{{Madlax}}'': Elenore Baker to Margaret.
* Harry Ord from ''Anime/TurnAGundam'' toward Queen Diana. He develops this toward Kihel as well (during her time spent pretending to be Diana), but his feelings toward her are tinged with a romantic interest, while his loyalty to Diana is completely platonic.
* Deconstructed in the anime ''VideoGame/{{Gungrave}}''. [[spoiler:Brandon's personal code which is this trope puts him under much torment when he has to choose between the best friend Harry and the father figure Big Daddy. Brandon's inability to choose ends up being one of the main causes of Brandon's downfall, which in turn leads to suffering of the people closest to Brandon. In the finale, Brandon admits that even though he is supposed to enforce the iron law of the syndicate to never betray, he just cannot shoot his best friend Harry]].
* [[SubmissiveBadass Berias']] attitude towards [[MagnificentBastard King Saralegui]] in ''LightNovel/KyoKaraMaoh'' seems to qualify.
* In ''Manga/{{Claymore}}'', Jean would go to literally suicidal lengths for Clare, as a result of IOweYouMyLife sentiment. Also, [[TheCaptain Miria]] tends to inspire this in most people she meets, especially fellow Claymores.
* Because they effectively [[StreetUrchin picked him off the streets]] and brought him up as one of their own, Firo from ''LightNovel/{{Baccano}}'' is unquestionably loyal to [[TheMafia the Martillo camorra family]] to the point that he'd kill or give up his own life on their order.
* Loyalty is a big deal in the ''VideoGame/SengokuBasara'' anime and games, given the subject matter, but Kojuuro and the rest of the Date clan really stand out in their loyalty to Date Masamune. In the anime's second season, Masamune's followers pile onto him bodily to protect him from Toyotomi Hideyoshi; a flashback in the following episode shows Kojuuro preparing to commit {{seppuku}} because he blamed himself for Masamune's arm being wounded in battle.
** Yukimura's loyalty to his master Shingen is completely unfathomable. He can't even imagine a world where the latter doesn't exist for him to serve.
* Zen from ''Manga/AkagamiNoShirayukihime'' manages to inspire this in all three of his retainers, though most strongly in his first retainer the knight Mitsuhide. Kiki knows she will have to leave his side as one of his knights eventually due to being next in line as head of an important noble family. Obi originally intended to just stick around for a short time since he had a personal policy of never forming strong ties with people, considering them fatal for people in his line of work. Eventually, when he realizes he's stayed too long as he's completely devoted to Zen ''and'' Shirayuki, he says he stayed in a troublesome place but no longer regrets it. The men in the fortresses he manages are also very loyal to him.
* Habaek in ''Manhwa/TheBrideOfTheWaterGod'' gave his first bride Nakbin the right to order his death, tried to follow her in death when she died, endured being separated from his current love Soah just to be with the resurrected Nakbin and when she died again, he honored her command not to look at someone with the same loving eyes he used to look at her [[spoiler:even to Soah when he specifically told her that he will look at Soah only with his one eye (metaphorically though since his damaged eye is completely healed as a god.)]]
* Several instances in ''Manga/FullmetalAlchemist'':
** The Mustang unit to their commanding officer (and also to one another). Particularly true of [[BodyguardCrush Hawkeye]], who at one point, refuses Mustang's direct order to abandon him and save herself if his attempt to expose the GovernmentConspiracy fails. It cuts both ways: Mustang will do anything to protect his subordinates (again, particularly Hawkeye, to the point of jeopardising a secret mission to save her).
** Greed's minions
** Fu and Lan Fan to Ling
** And of course, the Elric brothers to one another.
** The Briggs Brigade to Major-General Armstrong; Pride to Father.
** The Homunculi (sans Greed) to the BigBad of the series (Father in the manga and ''Brotherhood'' anime, [[spoiler:Dante]] in the [[Anime/FullmetalAlchemist 2003 anime]]). Within the Homunculi, Gluttony has this for Lust in both series, and also in both series, [[spoiler:her death affects him very badly]].
* A villain example but in Anime/{{Monster}}, PsychoForHire Roberto is unfailingly loyal to his master Johan Liebert. Though given that this is Johan Liebert, a man often compared to Hitler and the Devil himself, it's unlikely that he feels the same.
* ''Manga/{{Bleach}}''
** Yumichika is [[CoverBlowingSuperpower hiding his power]] because it betrays the divisional code of the 11th division. As a BloodKnight division, [[FunctionalMagic kidou]] and [[MagicKnight kidou-type zanpakutou]] are taboo but Yumichika's power is kidou-based. As a result, he fakes a shikai release so that he can adhere to the 11th division custom, meaning he [[WillfullyWeak doesn't use his abilities]] in battle and instead fights on [[{{Determinator}} sheer willpower alone]]. He's even [[HonourBeforeReason willing to die]] rather than be caught betraying his division. When he does use his abilities, he's [[AlmightyJanitor incredibly powerful.]]
** Tsukishima has an ability to deliberately invoke this trope to anyone he cuts. His power allows him to manipulate existing bonds so that a false bond between himself and the victim can be inserted and supersede the bond it's designed to override. He also has an Undying Loyalty of his own. [[spoiler:Ginjou was everything to him, having found him and looked after him from the time Tsukishima had been a small child. Tsukishima admits that Ginjou had taught him everything...except how to live without him.]]
** When Byakuya is brainwashed, his loyalty to Ichigo is so extreme that it gives him the power to kill his enemy--not because the brainwashing failed, but because he would kill even someone he loved if they were an enemy of Ichigo's. [[spoiler:Tsukishima learned the hard way that he had manipulated the wrong bond when he discovered that the emotional bond that most motivated Byakuya wasn't the bond between mentor and student, it was the bond between Byakuya and Ichigo.]]
** Komamura's UndyingLoyalty to [[BigGood Yamamoto]] stems from Yamamoto having once saved his life and always treating him well despite his appearance. [[spoiler:When Yamamoto enters battle against the Stern Ritters, both he and the Seventh Division are on the verge of catastrophic defeat. His response to Yamamoto's resolve to fight is to rally both himself ''and the entire Seventh Division'', much to the disbelief of Bambietta, who had thought she'd won and all but killed the squad.]]
** Katagiri was raised to be Ryuuken's personal servant and bodyguard. She will protect him no matter what the cost and her loyalty is to Ryuuken ''personally'', over and above her loyalty to the Ishida family. [[spoiler: So, when he [[HeroicBSOD believes]] he's failed his entire clan and tries to slink off forever into the GreyRainOfDepression, Katagiri tells him that if he leaves, she'll [[YouAreNotAlone abandon everything]] to go with him. Her speech brings him back to his senses.]]
** Taken UpToEleven in this case. Even ''after'' being zapped by Auswählen, Haschwalth doesn't consider Yhwach's act as a betrayal, but rather an honor and point of pride that Yhwach sees him as an asset worth absorbing. ''Damn...''
* Three of Shishio Makoto's [[QuirkyMinibossSquad Juppongatana]] in Manga/RurouniKenshin display undying loyalty to him. [[spoiler: Yumi uses herself as a distraction so that Shishio can stab Kenshin through her. Kamatari had to be deceived so that he did not follow Shishio in death. These two were in love with Shishio. The last, Houji, thoroughly subverts EvilChancellor. He is evil and he's Shishio's majordomo but he is utterly devoted to his leader. Enough to take the blame for an unpopular plan and risk the ire of the other Juppongatana. Enough to follow Shishio into hell. Even Shishio himself acknowledges Houji's loyalty]].
* Many Specters from ''Manga/SaintSeiyaTheLostCanvas'', notably [[MyMasterRightOrWrong Wyvern Rhadamanthys]] and [[NobleDemon Bennu Kagaho]].
* After Kotetsu wins his trust in the first half of ''Anime/TigerAndBunny'', Barnaby develops a fierce loyalty towards him to the point that staying by his side becomes his only reason for remaining a hero.
* ''Manga/DragonBall'':
** Puar for Yamcha. She's known him for ages, having been his partner in crime when the series first began.
** In ''Anime/DragonBallSuper'' Ginyu to Frieza. He waited almost two decades to find a proper body so he can return to Frieza's service once he's revived.
* ''Anime/MobileSuitGundam'''s [[SissyVillain M'Quve]] is loyal unto death to his [[LadyAndKnight lady]], [[LadyOfWar Kycilia Zabi]]. He carries out every order she gives him to the letter, lives to serve her, and uses his FamousLastWords to will her his prized possession. Many suspect that SubordinateExcuse is in full effect here.
* ''Franchise/LupinIII'': Inspector Zenigata has the ability (DependingOnTheWriter) to inspire this in cops from all over the world. His subordinates in the Japanese police have ignored orders from the Interpol to follow Zenigata, and in the special ''Voyage To Danger'' the Italian police, after trapping Lupin in an unescapable trap (Lupin himself was desperate), packed and let him go when they learned that Zenigata had been pulled from the case because ''if they got him in that occasion it would have meant that Zenigata hadn't been the one who arrested him''.
* Alucard of ''Manga/{{Hellsing}}'' has this for Integra Hellsing. On the Catholic side, the priests and nuns of Iscariot Section XIII are eternally loyal to BadassPreacher Alexander Anderson, most of whom were raised in his orphanage and view Anderson as a [[ParentalSubstitute surrogate father]].
* In ''Anime/RoninWarriors'', the true virtue the Ancient One imbued in Anubis' armor turns out to be Loyalty. After his HeelFaceTurn, Anubis shows why the armor chose him, remaining loyal to the Ronin Warriors and the Ancient One's memory [[spoiler:to the point of sacrificing himself to save the Warriors and Lady Kyra, the last member of the Ancient One's clan]].
* Rida to Veronica in ''Manga/BokuraNoKiseki''. This is mirrored in their [[{{Reincarnation}} reincarnations]], Takao and Harusumi, which tends to just make Harusumi uncomfortable.
* In ''Manga/{{Beelzebub}}'', the King's Crest is granted to those whose allegiance is sworn to a demon lord, which gives them a massive power boost. [[spoiler:As of Chapter 217, it has been revealed that all four members of the Tohoshinki bear Beel's King's Crest, all but stating that in some way, all of them are loyal to Oga (even if they never admit it)]].
** When questioned by Fuji on this, Himekawa laughs and states that Fuji's inability to comprehend the loyalty many of them have to Oga will be his downfall. [[spoiler:Considering that Himekawa willingly allowed himself to be turned to stone in order to give Oga time to escape and stall Fuji, he certainly embodies the trope as well]].
* In ''Manga/SoulEater'', Soul to his Meister Maka and vice versa, complete with DeclarationOfProtection and [[TakingTheBullet Taking the Bullets]]. This is also the general rule between Meisters and Weapons, and among Shibusen students at large.
* Despite the fact that their boss Dilandau treats them ''horrendously'' the Dragon Slayers in ''Anime/TheVisionOfEscaflowne'' are this to him [[spoiler:literally, since even after Van kills all of them their spirits intervene in order to protect Dilandau and allow him to escape]].
%%* All of the Senshi to Franchise/SailorMoon.
* Sarah Zabiarov from ''Anime/MobileSuitZetaGundam'' is devoted to her superior, Scirocco, something he actually ''reciprocates'' somewhat. [[spoiler:She's so loyal in fact that ''not even death'' stops her, her soul attempting to stop Kamille's Newtype-infused waverider attack on Scirocco himself. It takes Katz for her to finally step aside]].
* [[BattleButler Gilbert Nightray]] from ''Manga/PandoraHearts'' embodies the trope: he made a vow of loyalty to his master [[LonelyRichKid Oz Vessalius]] when they were kids, and [[SubordinateExcuse still calls himself Oz's servant as an adult,]] even after being adopted into [[FeudingFamilies a rival noble family]]. Then it turns out that [[spoiler:Gilbert has TraumaInducedAmnesia and was brainwashed so he would serve his master unconditionally. [[FailureKnight When he failed]], he decided to [[MyGreatestSecondChance atone by protecting Oz]]]]. But ''then'' it turns out that [[spoiler:Gilbert's previous master was Glen Baskerville, who forces him to shoot Oz. In the end, Gilbert breaks the spell binding him to Glen by ''[[AnArmAndALeg burning off his left arm]]'' [[ReconstructedTrope to make sure he will never betray Oz again]]]].
* ''Anime/PuellaMagiMadokaMagica'''s [[spoiler: Homura Akemi has a strong devotion to Madoka. She repeated the same month over and over again so that Madoka would be safe]]. WordOfGod [[spoiler:confirms this, stating that she was nearing the 100th try by the time the series ended]]. In the third movie, their descent into insanity is [[OOCIsSeriousBusiness marked]] by a startling willingness to brainwash this same person and trap her in a GildedCage.
* In ''Manga/MagiLabyrinthOfMagic'', it's common that people of strong standing or character happen to draw others to them.
** Aladdin, Alibaba and Morgiana. They will drop everything and anything to go help each other in need.
** Justified with a dungeon conquer and his/her Household, as such loyalty is needed to activate the Household vessels, such as Sinbad and his Eight Generals.
** Koumei and Kouha towards their older brother [[BigBrotherInstinct Kouen]]. Likewise, Kouha's soldiers are fiercely loyal to him because [[BecauseYouWereNiceToMe he took them in and cared for them]] when they were outcasts.
** The Djinns are this to their chosen king candidates and they are and remained King Solomon's most loyal allies even when [[spoiler:his actions motivated Al-Thamen to destroy Alma Torran]].
** The Three Magi to King Solomon, having been his closest friends and two of them knowing him since he was a young child. [[spoiler:Which makes it sadder that Arba aka Ren Gyokuen betrayed him in the end]].
** Muu to Scheherazade and WordOfGod says it is his fate due to being a descendant of Pernadius, Scheherazade's first king vessel. Meanwhile, the Fanalis Corps will follow him to whatever ends.
* The [[Anime/SailorMoon Sailor Senshi]] have this towards Usagi and Mamoru as their future Queen and King in the manga. In the original anime the Inners have this towards Usagi, but Haruka and Michiru take an entire season to come around.
** Jadeite from the first season is a villainous example. While the other three Generals are relatively obedient to Queen Beryl, Jadeite is the only one who's never questioned her, mouthed off, or given her some sort of cryptic answer when she demands an explanation of his plans. Even when his last failure ensures nothing but punishment for him, he returns to her without question.
** Zoisite has this for his mentor and lover Kunzite, even stating at one point that he would throw away his life for him.
** Sailor Neptune has this for her partner and lover, Sailor Uranus. Given the choice between not risking dooming the entire world and not risking Haruka's safety, she happily chooses to protect Haruka at the potential expense of the world, even surprising the villain forcing her to make such a choice. Though it isn't clear whether Michiru knew the villain was bluffing.
-->'''Sailor Neptune''': Maybe you misunderstood...A world without Haruka isn't a world worth saving. -
* In ''Anime/CrossAnge'', [[{{Meido}} Momoka]] is this for [[FallenPrincess Ange]], despite the latter found out that she's a Norma and thus [[UnPerson removed from human society.]]
* In ''LightNovel/TheBrideOfAdarshan'', Alec is fiercely loyal to his brother, the king of his country, to the point of having few motivations outside of serving him. The idea that he, as the prince, is in a position where he could usurp his brother never even occurs to him, making it a surprise to him when he discovers that others fear this.
* In ''Anime/MobileSuitGundamSEEDDestiny'', the three DOM Trooper pilots, Hilda, Mars, and Herbert, are very loyal to Lacus Clyne.
* Occurs in multiple places in ''Manga/TokyoGhoul'' and its sequel, '':RE''.
** The staff of Anteiku to [[BigGood Yoshimura]]. This results in two different outcomes, with [[spoiler: Yomo given the responsibility of getting the younger members to safety while Koma and Irimi stay with Yoshimura during his LastStand]].
** Banjou may be weak, but his trio of gas-masked followers are utterly loyal to him. When he swears loyalty to Kaneki, they follow suit without hesitation.
** In :Re, the employees of the [[TheClan Tsukiyama Group]] are completely devoted to their master. This is hinted to be a result of [[BecauseYouWereNiceToMe the kindness shown to them]] over the years, and the business empire allowing an untold number of Ghouls to live stable, relatively normal lives in human society. [[spoiler: When it all comes crashing down, [[PrincelyYoungMan Shuu]] is surprised at the massive number of Ghouls that show up to protect him out of loyalty to his father]].
** In a surprising twist, [[TortureTechnician Yamori]] is revealed posthumously to have [[PetTheDog inspired]] incredible loyalty among his followers. His NumberTwo, Naki, likewise inspires incredible loyalty after taking over the gang.
* Hisoka Kurosaki from ''Manga/DescendantsOfDarkness'', to his...[[HoYay "partner"]] Tsuzuki Asato. When the latter is going through the DespairEventHorizon, Hisoka assures him that he will always be there for him even if everyone else isn't. Later, when [[spoiler:Tsuzuki tries to commit suicide]], Hisoka, having given up on trying to reason with him, holds onto him so that [[spoiler:he'll die right by his side]].
* ''Manga/BlackButler'': All of the Phantomhive staff are eternally devoted to Ciel, for various reasons -- Tanaka because he'd been with the family since before Ciel was born, Sebastian because of their [[DealWithTheDevil contract]] (though it's hinted he genuinely likes Ciel, in a VitriolicBestBuds sort of way), and the rest because Ciel saved them from horrible lives and gave them a new purpose. [[spoiler: Though that one's also a TearJerker when we find out that Ciel and Sebastian manipulated them for the sake of their loyalty.]]
** Ciel himself is undyingly loyal to Queen Victoria. Whenever she has a mission for him, he drops everything on the spot in order to carry it out for her, even if he doesn't particularly like the assignment.
* Dune in ''Anime/CasshernSins.'' He was [[spoiler:Luna's bodyguard and was extremely royal to her. When he reunited with her again in the ruined world, he keeps his loyalty until the very end, despite Luna becoming a [[{{jerkass}} jerk]]]].
* Himari from ''Manga/OmamoriHimari'' combines this with a BodyguardCrush (that also happens to be her BerserkButton) towards protagonist Yuuto. Her willingness to die for him borders on being a DeathSeeker ([[spoiler:parially due to her also being [[TheAtoner an Atoner]]]]), and in the finale of the manga [[spoiler:her loyalty is literally undying, allowing her to come back from the afterlife.]]
* In ''Anime/{{Endride}}'', most of the [[LaResistance Ignauts]] feel intense loyalty toward [[RebelLeader Demetrio]], willing to [[TakeMeInstead offer their lives in exchange for his]] even, but Felix and Mischa especially embody this trope, going out of their way to distrust people on Demetrio's behalf because he tends to be [[EasilyForgiven quick to mercy]].
* In ''Manga/Brave10'', many of the Braves end up feeling this towards Yukimura and the lands of Ueda, even Saizo, to his own surprise. The best examples of this trope among the cast are Sasuke, Rokuro and (in the sequel) Nanakuma, all of whom never waver and will pursue loyalty past the point of reason.
* In ''LightNovel/DestructionFlagOtome'', Katarina went from a SpoiledBrat to a CloudCuckoolander almost literally overnight. Her personal maid Anne had pretty much given up on ever thinking of herself as more of a YesMan tool to more important people, but the new Katarina was impossible to predict or suck up to and, more importantly, began treating Anne like a big sister or close friend. Anne is occasionally [[ServileSnarker exasperated]] at her charge but is secretly fiercely loyal and would do anything for her.

[[folder:Comic Books]]
* Franchise/{{Batman}} has had his ups and downs throughout the years, and had his scrapes with many a hero, but he will ''never'' be abandoned by Alfred.
** Perfectly demonstrated in ''Film/BatmanBegins'':
--->'''Bruce Wayne:''' I wanted to save Gotham. I've failed.\\
'''Alfred:''' Why do we fall, sir?\\
'''Alfred:''' So that we can learn to pick ourselves up.\\
'''Bruce:''' You still haven't given up on me?\\
'''Alfred:''' Never.
** Well, usually. Sometimes Batman's jerkiness is too much for him and he'll leave for a time. "Venom" and "Officer Down" are two such stories where this happened.
*** Sometimes, Alfred quits when Bruce has decided to ruthlessly risk his own life only for his stubborness. Alfred said that he would not allow him to destroy himself and so, by abandoning Batman he could show his true loyalty to him.
** [[ComicBook/RobinSeries Red Robin]]/Tim Drake is this. Batman notes that loyalty is his prime motivation, and his loyalty to his father caused his TenMinuteRetirement. So when Batman apparently dies, he goes DarkerAndEdgier, and tries to prove he is alive. Undying loyalty doesn't change regardless of who dies.
** In the story arc "Death of the Family", [[spoiler: the Joker's torment of the Batfamily via Joker venom has shaken them physically and caused a great loss of faith in each other and in themselves. So when Bruce calls a meeting, no one except Alfred attends. However, outside the Wayne Manor, someone still stands, the first Robin, Dick Grayson.]]
* If any MarvelUniverse hero inspires and has this as a defining trait, it's ComicBook/CaptainAmerica. Every single hero worth his salt in the Marvel U trusts Cap unconditionally, [[NoOneGetsLeftBehind cause Cap will go through hell and back to not leave any of them behind]]. Even someone as hard to work with as ComicBook/TheIncredibleHulk has Cap as the one person he'd never raise a finger to.
** Cap himself has undying loyalty to not America as a ''nation'' but rather America's ''ideals''. When the government has asked him to do things that he felt were against those ideals, he's either quit being Captain America or gone rogue.
--->'''Captain America:''' I'm loyal to nothing, General... except the Dream.
* ComicBook/KryptoTheSuperDog. Not even being cloned makes him less loyal to the Kryptonians.
-->'''Max Lord:''' We talked about this! Don't clone the dog! Dogs are weird! The whole loyalty thing just seems to be branded right in on a genetic level, for Pete's sake!
* Extreme loyalty (to Superman) was intended to be ComicBook/JimmyOlsen's foremost quality. (Because of the PublicityDerailment of UsefulNotes/{{the Silver Age|of Comic Books}}, it wasn't always portrayed very well.) This is exemplified in the ''Franchise/{{Superman}}'' storyline, ''ComicBook/SupermanTruth'', ComicBook/JimmyOlsen stands by Superman's side after ComicBook/LoisLane blows his secret identity to the entire world (it probably helps that Supes revealed his identity to him just prior to the shit hitting the fan). Jimmy also shows that there's an entire neighborhood who is happy to have Superman around and renamed their area as "Kentville".
* Dexter of the [[GreenLantern Red Lantern Corps]] is a former housecat who actually became an AntiHero[=/=]AntiVillain out of sheer loyalty to his former owner.
--> I find ones who hurt you. I kill. [[TearJerker I good kitty]].
* Comicbook/DoctorStrange
** Wong, Strange's manservant and friend, is his one constant companion. He even sticks around after Strange relinquishes the title of Sorcerer Supreme and joins the New Avengers.
** Wong's loyalty is most assuredly returned. In the Doctor Strange story, "The Oath", Strange goes through great lengths to save his manservant when he discovers Wong is suffering from an inoperable brain tumor.
* ''ComicBook/DuckTales'': In "Down But Not Out in Duckburg", Scrooge comes home to discover that Glomgold has gotten control of all his businesses and even the city in his absence. Despite the fact that he's now just a poor old man, the others stick with him until he finds a way to restore the status quo.
* [[http://9gag.com/gag/2478950 This]] one panel strip.
* In ''Franchise/{{Tintin}}'' album ''[[Recap/TintinCigarsOfThePharaoh Cigars of the Pharaoh]]'', LoyalAnimalCompanion Snowy thinks that Tintin is dead, so he resigns himself to spending the rest of his life at his grave.
* ComicBook/{{Richie Rich}}'s butler, Cadbury. Try to bribe him, and you're entering BullyingADragon territory. Emphasized in one story where a foreign government [[SecretTestOfCharacter did it to test him]] because they wanted to offer him a position as Prime Minister; he ''turned down the offer'' because he felt the test only showed he was needed in his current job.
* Harley Quinn to [[SelfDemonstrating/TheJoker her "puddin'"]]. Of course given that this is the Joker we're talking about it is not returned. [[spoiler: ''ComicBook/DeathOfTheFamily'' subverts it. She ends up fighting back, and escapes him. She also declares that while she may love him, that does not mean that she belongs to him]].
* In ''StarWars'' ''ComicBook/{{Legacy}}'', this is expected of all of the [[ReligionOfEvil One Sith]] towards their Dark Lord, [[DarkMessiah Darth Krayt]], and his cause. In practice, however, considering how ambition is a cardinal Sith trait, the main Sith characters tend to interpret this very differently:
** [[DarkActionGirl Darth Talon]] is easily the most loyal to Krayt personally; she makes it plain she'd kill herself if she thought he needed her to and [[spoiler: after he comes BackFromTheDead, she's the first he contacts]].
** [[BloodKnight Darth Stryfe]] is totally loyal to the position of Dark Lord, which normally means Krayt, and he's [[LargeHam not exactly shy about making sure everyone knows]]. [[spoiler: However, when Krayt and Wyyrlok fight it out for the title, Stryfe stays out of it, assuming that whoever wins will be the superior leader. When that's Krayt, Stryfe reaffirms his loyalty]].
** [[MadScientist Darth Maladi]] is more ambiguous; she's loyal to Krayt, but unlike the above two she's perfectly willing to question his judgment or operate independently for a time if it suits her. At the end of the day, though, everything she does is ultimately put to the use of Krayt's cause, though Krayt himself thinks Maladi [[ForTheEvulz would do it all for its own sake anyway]].
** [[TheStarscream Darth Nihl]] defies this; he was an independant warlord before he was a Sith, and he's loyal to Krayt only for the power he grants his followers and fairly openly questions him and schemes against him. [[spoiler: When Krayt dies his final death, Nihl ''immediately'' takes command, has Krayt's EliteMooks killed when they object, and gets the heck out of dodge]].
** [[TheConsigliere Darth Wyyrlok III]] is easily the most interesting. He is ''absolutely'' loyal--to the Sith cause, which Krayt and everyone else takes to mean loyalty to Krayt himself. [[spoiler: Not quite. When Krayt goes into an extended VillainousBreakdown, Wyyrlok decides he's become a liability, promptly kills him off, and takes command himself, all in the name of the greater glory of the Sith. Pity for Wyyrlok that Krayt CameBackStrong]].
* It's rather disturbing to see how unflinchingly loyal most of the minions of the ComicBook/RedSkull are to their horrible monster of a boss. Of course, most of them are almost as evil as him. The most notable example of this is Crossbones, who hero-worships Red Skull, searched constantly for him when Magneto abducted him and nursed him back to health despite Skull being on the verge of suicide, and made it his mission to kill and destroy as much of America as he could after Skull's apparent death.
* [[TragicVillain Time may pass, and hearts may break]], [[Franchise/{{Batman}} but Victor Fries]] [[IWantMyBelovedToBeHappy will always be a married man]].
* In the ''ComicBook/TransformersShatteredGlass'' [[MirrorUniverse universe]], Starscream is not just loyal, but almost disturbingly devoted to the heroic Megatron.
* [[ComicBook/StarWarsDarthVader Doctor Aphra]] is absolutely devoted to Darth Vader. Not just out of fear (though there is a fair helping of that), but also because she's a [[AdmiringTheAbomination massive fangirl]]. She continues to serve him, even knowing that he'll probably [[YouHaveOutlivedYourUsefulness eliminate her eventually]]; in fact, she fully expects it, and at the end of their first mission together outright tells him to do it because she's now [[HeKnowsTooMuch too much of a security risk]], calling him stupid to his face when he refuses.

[[folder:Fan Works]]
* ''Webcomic/AxisPowersHetalia'' fanfic ''[[https://www.fanfiction.net/s/11886910/1/Gankona-Unnachgiebig-Unità Gankona, Unnachgiebig, Unità]]'': It was because of their immense trust in Italy that Germany and Japan even agreed to share him. It was because of their immense trust in Italy that neither tried to undermine the other while being in a relationship with Italy. [[spoiler:This leads to a [[{{Polyamory}} polyamorous]] among the three [[OneTrueThreesome with all being in love with each other]].]]
* ''Fanfic/ACrownOfStars'': Shinji refuses leaving Asuka alone because he did it in the past and the consequences were horrible. She tried to commit suicide, she got torn into pieces and eaten alive, she was raped by monsters... so that he promised that he would always get her back and would never leave her side.
** In chapter 54, after an episode of strong self-doubt Shinji declares Asuka he loves her, he is completely devoted to her, he would do anything for her and he is hers for as long as she wants her. Asuka feels utterly overwhelmed because she thinks she does not deserve that level of loyalty.
* ''Fanfic/AdviceAndTrust'': In chapter 2 as -he believes- Asuka sleeps, Shinji swears he will be hers always and forever. Throughout the story he sticks by her through thick and thin, and insists he will go whenever she goes.
* ''Fanfic/TheChildOfLove'': Shinji told Asuka he would never leave her or cheat on her and if he hurts her he will only hurt himself.
* ''Fanfic/ChildrenOfAnElderGod'': In chapter 23 Shinji pleaded Asuka not leaving him. She replied she will not leave him, ever. Later [[spoiler:when they are considering leaving human civilization after the war,]] Asuka tells plaintively she will go wherever Shinji goes. She never considered parting with him.
-->'''Shinji''':''"I love you too, Asuka. Don't ever leave me. Please."''\\
'''Asuka''':''"I won't, [...] Never."''
* ''FanFic/TheDifferentverse'': Coco has this to Applejack and her family after Applejack, on the way out of Manehatten, found her crying from being bullied (due to having recently lost her parents) and, knowing how she felt from personal experience, offered her a home.
* ''Manga/{{Evangelion 303}}'': In chapter 13 [[spoiler:Shinji pops the question to Asuka.]] She asks if he really wants to tie himself to a nutcase like her and if he can promise he will be true to her for the rest of his life. He does.
* In ''Fanfic/GhostsOfEvangelion'' Shinji promised that he would take care of Asuka. And he looked after her until the end. He never dated other women, either.
* ''Fanfic/{{HERZ}}'': Since he met her Shinji was single-mindedly fixated on Asuka, even if for many years she seemed hating him. In chapter two, during a breakdown Asuka pleads Shinji not leaving her, and he answers he is and has always been hers and he would never leave her.
* ''Fanfic/LastChildOfKrypton'': In chapter 9 of the rewrite when Shinji confesses his feelings Asuka demands this from him. He answers she already has it.
* ''Fanfic/NeonGenesisEvangelionGenocide'':
** When Asuka tells Shinji that he should just leave her before she hurts him, he replies he will not leave her because he wants to be with her forever.
--->'''Asuka:''' Please, leave. Just leave. I don't want to hurt you anymore.\\
'''Shinji:''' I'm … not going to leave.\\
'''Asuka:''' Then I'm just going to keep kicking you.\\
'''Shinji:''' I am not going to leave! I don't care how much you hurt me. Break every bone in my body if it makes you happy, but I am not going to leave you!\\
'''Asuka:''' But...\\
'''Shinji:''' Why can't you understand? I want to be there when you need me!\\
'''Asuka:''' I don't need you! I don't want to need you!\\
'''Shinji:''' But I need you! And I want to be with you forever!\\
'''Asuka:''' You … what? Why?\\
'''Shinji:''' You told me that if I couldn't live for myself, then … I should live for those around me. I … I can't live for myself, Asuka. So I'll live for someone else instead. I'll live for you."
** Argued by Misato and Ritsuko, and in chapter 7 by Gendo and Fuyutsuki:
--->'''Gendo:''' “Loyalty never dies.”
* ''Fanfic/TheOneILoveIs'': When Asuka [[spoiler:falls in a coma after the FinalBattle]] Shinjij promises he will always wait for her, not matter what.
-->''"I'll wait for you, Asuka. Even if it means waiting all my life..."''
* ''Fanfic/ScarTissue'': After Third Impact Shinji told Asuka his life was hers and she could do whatever she wanted with him. Unfortunately her mind was so broken due to all she had gone through that she abused him for months until she realized what her actions were wrong and stopped. Even so he remained by her side trying to support her until she got better.
* In the ''WesternAnimation/JackieChanAdventures'' fic ''FanFic/QueenOfAllOni'', [[CoDragons Left and Right]] (Left especially) feel this way towards Jade. As Left puts it, in his thoughts,
-->"They were her bodyguards, she was the one who had raised them to awareness and granted them power. Thought and the power to act on it, boons that to Left could never be fully repaid."
** Ozeki, the General of the Sumo Khan, feels this way to Jade as well, having only served Tarakudo until female Shadowkhan could rise again.
** [[DarkActionGirl Hebi]] [[spoiler: ([[FaceHeelTurn formerly Viper]])]] is specifically [[BrainwashedAndCrazy conditioned]] to be this to Jade as well.
* ''FanFic/InnerDemons'': [[TheDragon Trixie]] to [[BigBad Queen]]![[FaceHeelTurn Twilight]], out of [[BodyguardCrush love]]. [[spoiler: Until literally her last breath, as she [[TakingTheBullet takes a sword]] for her and dies]].
** As the sequels prove, it's a literal case of undying loyalty, Trixie's love for Twilight having lasted over millennia, due to {{Reincarnation}}.
* The PeggySue fic ''[[http://www.fanfiction.net/s/5193644/1/Time-Braid Time Braid]]'' has this between [[AllLovingHero Naruto]], [[{{Yandere}} Hinata]], and [[DivineParentage Sakura]]. It's especially prevalent with Hinata to Naruto as well as Sakura and Hinata to each other. Hinata whether she's [[BrainwashedAndCrazy brainwashed]] or has [[DealWithTheDevil sold her soul]] refuses to fight Naruto. Sakura (to whom Hinata sold her soul) gives up a chance at godhood because [[YouAreWorthHell Hinata is damned for selling her soul]].
* In ''Fanfic/ChildOfTheStorm'', while rarely explicitly stated, [[TrueCompanions the Avengers]] all have this towards each other.
** In reference to the above, Natasha's former mentor and father figure Ivan Petrovich comments on how the Avengers have her loyalty, in tones that imply that this is a very rare thing indeed.
** If Harry decides that you're his friend, there is no limit to how far he will go for you.
** [[spoiler: The Winter Soldier's]] loyalty to Natasha is perhaps one of his defining traits, and she is a key motivator in his [[spoiler: breaking free of his brainwashing and resultant HeelFaceTurn]].
* In ''FanFic/FallenKing'', Joey is constantly asking himself what Yugi would do, and a lot of his actions stem from wanting to honor Yugi's memory.
* Taken to an unhealthy level in ''{{FanFic/Zenith}}''. Spike is always loyal to Twilight, [[spoiler:even as she's lying comatose in the hospital]].
* In ''Fanfic/{{Cultstuck}}'', [[NobleBigot Equius]] betrays [[TheEmpire Alternia]] to protect Nepeta, a suspected rebel against the Condesce.
* In the ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' fanfic Fanfic/MLPCollateralDamage, Princess Ceymi feels this for the other Changelings of Hive Chrysalis, even as she is increasingly-alienated from Queen Chrysalis herself.
* In ''[[https://www.fanfiction.net/s/6348510/1/Rising-of-the-Dark Rising of the Dark]]'' Manga/{{Naruto}}, [[OurDwarvesAreAllTheSame Hagwin]], and [[OurElvesAreBetter Celia]] all share absolute loyalty for each other, going so far as to willingly wage war on roughly half the world for each other.
* [[Fanfic/DeliverUsFromEvilSeries Mortality]] has this and definitely between Holmes and [[TheLeader Watson,]] though [[HyperCompetentSidekick Wiggins,]] Mary, [[TheLestrade Lestrade,]] [[JerkWithAHeartOfGold Gregson]] and Mrs. Hudson qualify as well, but Holmes and Watson especially. If you think about it, despite the fact that Holmes was [[ColdBloodedTorture getting tortured with an inch of his life]] he wasn't afraid to exchange his life for his friend's. For his part, Watson [[TranquilFury calmly and coldly]] told the criminal he was interrogating "''[[BewaretheNiceOnes if your]] [[TheDragon master's]] [[TheDragon actions]] [[BewaretheNiceOnes destroy him whom I regard as,]] [[BewaretheNiceones as the best and wisest man I have ever known]]'' ''[[DeadlyDoctor make no mistake that I shall hunt down, to a man,]] [[DeadlyDoctor everyone who played a part in his destruction."]]'' He even ''killed'' Culverton Smith, most likely with his [[DeadlyDoctor medical skills]] and also [[ScrewTheRulesImDoingWhatsRight broke the law with no regrets]].
** Oh, and Watson most likely [[GoodIsNotSoft murdered the captured criminal]] when he [[VillainsWantMercy stupidly begged for mercy]]. [[TooDumbToLive Nice going, you idiot.]]
* Creator/RoseOfPollux's ''Doctor Who'' fanfics have this between Jamie and all of the Doctors in spades. This makes for many heartwarming moments.
* ''FanFic/QueenOfShadows'': The Shadowkhan race as a whole has this for [[GodEmperor the Queen lineage]]. Whatever other divisions they may have amongst themselves, they are all united in serving the Queens no matter what, and striking down anyone who threatens them.
* ''Fanfic/ThousandShinji'': When Asuka tells Shinji that she is afraid of losing him, Shinji replies she will never lose him. When Asuka muses he can not promise that, Shinji replies he can and he does and, even if he died, his soul would find his way back to her from whatever afterlife he found.
* In ''[[https://www.fanfiction.net/s/8501689/1/The-Havoc-side-of-the-Force The Havoc Side of the Force]]'', Harry Potter manages to inspire this in everyone he befriends on any level, partially because he's such a BenevolentBoss. Anakin's mother was offered a position in Chancellor Palpatine's retinue but turned it down so she could stay a kitchen hand on Harry's ship. A minister goes out of her way to have a former lieutenant in Naboo's military work for Harry and openly lies to the committee investigating him. Lastly, Anakin makes it clear that his friendship to Harry far outweighs his loyalty to the Jedi Order (at least partially because Harry's the reason Anakin could buy his mother's freedom).
* In ''FanFic/RobbReturns'', Quill, one of Jon Arryn's men, has this towards the Lord of the Eyrie himself.
** The North in general to Eddard Stark, particularly now that it is obvious that it will fall upon him the task of leading Westeros in the fight against the Others.
* [[https://www.fimfiction.net/story/346369/chrono-reflect Chrono Reflect]] has Standard and Machine Rainbow Dash. However, with Standard Rainbow this is portrayed negatively, as she is a loyal friend to Standard Fluttershy, a bully who goes out of her way to treat her like dirt.
* Theirs may be an OddFriendship, but FireForgedFriends Mahanon and Victoria have this for one another without question in ''[[Fanfic/TwiceUponAnAge All This Sh*t is Twice as Weird]]''. Even when they're not anywhere near one another, they will defend each other without hesitation.
* ''[[https://www.fanfiction.net/s/12519489/7/A-Dragon-s-Flight A Dragon's Flight]]'' gives this at House Velaryon for the Targaryens. When Visenya Targaryen comes to them for help, they ''immediately'' grant her shelter, showing her the respect a royal princess is due and already plotting to give her back the Iron Throne.
* ''FanFic/WarOfTheBiju'': Much like in canon, not even ''death'' will break Itachi's loyalty to Konoha. Even though Naruto is younger than him by several years and was named Hokage ''after'' his death, Itachi still willingly goes to one knee before him and acknowledges him as his Hokage.
* ''FanFic/SonOfTheSevenKingdoms'': William tends to inspire this in those around him. The Blades, the Legions, and the Dawnguard are all loyal to him to the last member, and his closest friends view him as a brother.
* ''Fanfic/{{Dauntless}}'': Everyone who works for Lelouch is loyal to literally suicidal extremes. When Lelouch is badly injured in Area 11, his entire former squad (including their Number mechanic who'd be executed for it) go AWOL to be by his side, unknowing that Lelouch requested their transfer over a month prior and thus they wouldn't be court-martialed. One of Lelouch's squad mates was furious with another member because Lelouch had to put himself in danger to save him. Most notably, Lelouch's former comrade Lukas declines an offer to be Euphemia's knight (one of the highest honors any soldier can receive) because he wouldn't be able to serve under Lelouch if he accepted.

* Khan to Disney/{{Mulan}}. Seriously, he was prepared to go into the middle of a raging avalanche to go save her.
* ''WesternAnimation/ToyStory'': Woody to Andy. He won't, under any circumstances, ever turn his back on his owner and religiously believes it's his duty to be there when Andy needs him.
** Slinky to Woody, to the point where it almost destroyed him.
** Bullseye to Woody, fitting the television series they are toys of. In the beginning of ''Toy Story 3'', he's the only toy who wants to return to Andy's with Woody, only to be stopped because Woody doesn't want him to be alone in the attic.
* In ''WesternAnimation/TheCurseOfTheWereRabbit'' Gromit stays loyal to Wallace even after it turns out [[spoiler:Wallace is the were-rabbit]].
-->'''Victor Quartermaine:''' Your loyalty is moving. Sadly, you won't be.
* [[PluckyComicRelief Olaf]] from ''Disney/{{Frozen}}''; even when he discovers that [[spoiler:fire will melt him, he still stays to warm Anna as her curse freezes her]].
* In the ''WesternAnimation/HowToTrainYourDragon'' movies, this is the bond which develops between dragons and their riders, and most particularly between Hiccup and Toothless. In the [[WesternAnimation/HowToTrainYourDragon2 second film]], we see that this loyalty [[spoiler:actually allows Hiccup to break the MindControl being held over Toothless by the BigBad]].
* In ''WesternAnimation/InsideOut'', [[spoiler: Bing Bong]] is faithful to Riley to the point of [[spoiler: pulling a HeroicSacrifice to save her from her depression.]]
** More humorously, Riley's imaginary boyfriends die to help Joy get back to headquarters.
* ''WesternAnimation/{{Coco}}'': The animal companions of the Riveras.
** Dante remains loyal to Miguel [[spoiler:even after the latter refers to him as a dumb dog. It turns out Dante was trying to help Miguel stay away from the man who murdered his great-great-grandfather]].
** Pepita, Imelda's large alebrije cat, has remain loyal to the Rivera family since their deaths. [[spoiler:She is ultimately the one who punishes Ernesto De La Cruz for the crimes he's committed against them since murdering her master's husband]].

[[folder:Film - Live Action]]
* In the ''Franchise/BackToTheFuture'' series, Marty [=McFly=] shows this towards anyone he cares about. No matter how much his parents' actions in both the past and present annoy or upset him, he will never let anyone get away with hurting George or Lorraine in the long run. He shows this towards Doc as well. In the first movie, he tried everything he could think of to make sure that Doc found out about his death in the future, and in the third movie, he refused to go straight home to the future once he found out that Doc was killed in 1885, insisting on going back to rescue him despite Doc's explicit directions to the contrary and saving Doc repeatedly from Buford once he got there.
* [[BadassNormal Anguirus]] is Franchise/{{Godzilla}}'s most loyal ally, even willing to risk his own life if it means helping his fellow kaiju.
** Ironically enough, Anguirus was the very first monster Godzilla ever fought. DefeatMeansFriendship, indeed!
** A prime example of Anguirus's loyalty towards Godzilla can be seen in the 1974 film ''Film/GodzillaVsMechagodzilla''. In it, after [[spoiler:losing to the Mechagodzilla (disguised as the real Godzilla)]] he goes to warn Godzilla about the impending danger even after [[spoiler:Mechagodzilla had broken Anguirus's jaw and pretty much beat the living daylights out of him]].
** In ''Film/GodzillaFinalWars'', Anguirus is released by the Xilians alongside Rodan and King Caesar (Godzilla's other two allies in the Showa series) to stop Godzilla at Mount Fuji. Anguirus and Godzilla have a short conversation before Godzilla gives a sharp backward jerk of his head after Anguirus roars something and charges into battle, as if he's shocked that Anguirus would actually fight against him. Fortunately, Godzilla leaves his three former allies in a comical heap, sparing them from death.
* Bob from the 1989 ''Film/{{Batman}}'' film proves this trope isn't just for good characters. He always, ''always'' has The Joker's back covered and follows his boss' every order without question, even when Joker asks to borrow Bob's gun so he can [[spoiler: [[KickTheDog shoot Bob dead just for the hell of it]]]].
* Bane's henchmen display this in ''Film/TheDarkKnightRises''; one of them is willing to die in a plane crash just because Bane needs his enemies to find the right number of bodies in the wreckage, and another two dutifully carry out his orders even after he's made it perfectly clear that [[YouHaveFailedMe their actions have potentially jeopardized his plans and he intends to execute them as punishment]].
* By the end of ''Film/StarTrekIntoDarkness'', it's become obvious that the crew of the ''Enterprise'' have [[TrueCompanions developed this with one another]] [[spoiler: after they refused Spock's orders to abandon ship]]. Even early into the movie, both Scott and Spock continue to refer to Kirk as Captain despite him (temporarily) losing his rank.
%%* Holmes and Watson are this to each other in ''Film/SherlockHolmes2009'' and ''Film/SherlockHolmesAGameOfShadows''.
* ''Film/XMenFilmSeries''
** ''Film/TheWolverine'':\\\
Harada to Mariko, despite his allegiance with Viper. [[DeclarationOfProtection He pledges to protect her at her grandfather's funeral]]. He also chooses to [[spoiler:help Mariko and Wolverine in the end of film at the cost of his life, despite [[IWantMyBelovedToBeHappy it's also pretty clear for him]] that Mariko and Wolverine are already bordering on OfficialCouple]].\\\
Yukio To Mariko, her fictive [[spoiler:and later officially adoptive]] big sister.
** Hank [=McCoy=] to Charles Xavier. From the Cuban Missile Crisis in 1962 to the rise of the Sentinels in the BadFuture, Hank always remains at Xavier's and the X-Men's side. And he won't hesitate to protect him, either.
*** In ''Film/XMenDaysOfFuturePast'', there are plenty of other things that Hank could do with his time, yet he chooses to take care of Charles during the latter's decade-long HeroicBSOD. Hank may even be a little ''too'' loyal because he serves as an enabler by providing a serum which worsens his friend's already bad case of substance abuse.
* Franchise/MarvelCinematicUniverse: Arguably the biggest overarching theme of the three ''Captain America'' films is the relationship between childhood best friends Steve Rogers and Bucky Barnes. The level of devotion they have towards each other gives them both a reason to live, but also an incredible amount of pain.
** In ''Film/CaptainAmericaTheFirstAvenger'', Steve went AWOL and went behind enemy lines ''alone'' just to go rescue Bucky, and Bucky would follow him through hell and back.
** The sequel, ''Film/CaptainAmericaTheWinterSoldier'', highlights the strength of this relationship, where after [[spoiler:it is revealed that Bucky is the Winter Soldier]], Steve admits that "Even when I had nothing--I had Bucky." [[spoiler:When Sam tries to tell Steve that no matter who Bucky used to be, Steve may have to stop him, not save him, Steve says that he recognizes that, but that he also recognizes that if it ever came to that point, he wouldn't be able to do it. In turn, the Winter Soldier's 70 years worth of programming and brainwashing started to crack from hearing Steve say his nickname ''once'']].
-->"[[MeaningfulEcho I'm with you to the end of the line]]."
** The last film of the trilogy, ''Film/CaptainAmericaCivilWar'', establishes that there is nothing in the world Steve wouldn't do for Bucky. [[spoiler:He becomes a fugitive, desecrating his reputation and legacy, and splits up the Avengers, all just to protect Bucky, who, after the death of Peggy Carter, is the last tie to his old life and the only family he has left. On Bucky's end, according to his [[Creator/SebastianStan actor]], the only reason he has't put a bullet through his head after regaining his memories and committing suicide is because of Steve. He's so wracked up with guilt over the crimes he committed as the Winter Soldier that he believes that he isn't worthy of the lengths Steve is willing to go to protect him, and deliberately stays away because of that. That being said, killing himself would only cause Steve even more pain and make things worse. The entire conflict of the film boils down to the fact that Steve will never abandon Bucky, for as long as they live]].
* Diaval maintains this for his oddly Evil-But-BenevolentBoss, {{Film/Maleficent}}, after she saves his life. Even if he doesn't always like what she asks of him, he still does it, and when she tries to send him away rather than insist he risk his life fighting by her side, he (with comedic grumpiness) refuses. To her credit, Maleficent genuinely seems to appreciate his loyalty; he's pretty much the only one she trusts at all.
* One of Eggsy's strongest and most important traits in ''Film/KingsmanTheSecretService''. His refusal to rat out his friends to the police nearly got him imprisoned and it's clear that even the threat of death won't make him betray the Kingsmen, particularly [[ParentalSubstitute Harry]]. In this regard, his EvilCounterpart would be Gazelle.
* Villainous example in ''Film/BigGame'' - Hazar's helicopter pilot refuses to leave his boss even after Morris shoots his fellow mook and threatens to do the same with him.
* In ''Film/JurassicWorld'':
** Despite the ''I. rex'' standing right behind them, all it takes is some close contact with ParentalSubstitute Owen for Delta, Echo, and Blue to [[spoiler: turn against the ''I. rex'' and fight to the death to protect him.]] Charlie also hesitates and appears to reconsider their betrayal as soon as she sees Owen in the firefight. [[spoiler: [[TearJerker It gets her killed.]]]]
** Lowery Cruthers, the main member of MissionControl, has this towards both Claire and the titular park. Despite his less-than-pleased view on Claire's more questionable decisions (approving of the ''[[ObviouslyEvil Indominus rex]]'', for example) he's there for her until the very end, willingly staying behind even as the rest of the control room is evacuated because, as he puts it, "someone has to". It's a good thing he did, too, because [[spoiler:Claire's next plan involved releasing the ''T. rex'' to fight the ''Indominus'', something she never could have done if Lowery had left the control room]].
* ''Film/RiseOfThePlanetOfTheApes'': Caesar seems to inspire this in most of the apes he meets. He let the gorilla Buck out of his cage and [[spoiler:Buck ended up sacrificing himself to protect him]]. He defeated Rocket and [[DefeatMeansFriendship offered him cookie]] and Rocket in time became one of Caesar's most loyal followers.

* Hagrid is extremely loyal to Dumbledore in ''Literature/HarryPotter'', probably more so than any other person.
** [[spoiler:Sirius Black]] has put himself through a ''lot'' out of loyalty to [[TheHero Harry]] and [[BrilliantButLazy his (now-deceased) father]], who was Sirius's best friend.
** Possibly the best example of this trope in the series is [[spoiler: Severus Snape]]. Readers (and every character, except for [[spoiler:Dumbledore]]) don't learn of [[spoiler:Snape's]] loyalty, sacrifice, or the circumstances of it until the end of the last book, though it has defined him the whole time. In addition to [[spoiler:Snape's]] loyalty to [[spoiler:Dumbledore, he devoted the rest of his life to protecting Harry Potter, the son of his lost love Lily, and ultimately dies in his efforts to save him]].
** Also, [[TheLancer Ron's]] loyalty to [[TheChosenOne Harry]] is repeatedly mentioned. They have a couple of instances where they're on the outs (they ''are'' teenage boys), but on the whole they're practically brothers, and Ron stands wandless on a broken leg to get in between Harry and someone he thinks is trying to kill him in ''[[Literature/HarryPotterAndThePrisonerOfAzkaban PoA]]'' saying they'd have to kill him to get at Harry. [[spoiler:The "practically" is erased after [[OfficialCouple Harry marries Ginny]] in the epilogue as they become brothers-in-law]].
** Harry's loyalty to Dumbledore is tested throughout books 5, 6, and 7. Even after learning about Dumbledore's DarkAndTroubledPast and his FeetOfClay, Harry's loyalty to his mentor is unquestionable. "Dumbledore's man, through and through" indeed.
** Villainous example: [[TheDragon Bellatrix Lestrange]] is completely loyal to [[BigBad Voldemort,]] to the point of proudly going to Azkaban for him.
** Dobby is always willing to help Harry, whether it's [[Literature/HarryPotterAndTheGobletOfFire helping him in the Triwizard Tournament]], [[Literature/HarryPotterAndTheOrderOfThePhoenix finding him training space for his rebellion]], or [[Literature/HarryPotterAndTheChamberOfSecrets warning him of danger]], he'll do it. [[spoiler:His loyalty eventually [[Literature/HarryPotterAndTheDeathlyHallows costs him his life]].]]
* [[TheChampion Sam Gamgee]] is Frodo's servant in ''Literature/TheLordOfTheRings''. [[{{Determinator}} He followed him into]] ''{{Mordor}}'' for no other reason than loyalty. It is proverbial among Tolkienites.
** Aragorn, Gimli and Legolas spend several ''days'' giving chase on foot to the orcs who captured Merry and Pippin. Aragorn outright states that they will continue looking for them even, if in the end, all they can do for them is starve to death together.
** Also, Merry towards Éowyn, Éowyn towards Théoden, and Pippin towards Faramir.
** The Goblins of Goblin-town in ''Literature/TheHobbit'' to the Great Goblin, even after he is [[NiceJobBreakingItHero killed by Gandalf trying to save the dwarves and Bilbo]]. The Great Goblin and his minions believed the dwarves were plotting against them when they discovered the dwarves in their territory, but we know they were really trying to head to the Lonely Mountain to confront Smaug the Dragon. This was cemented further when the Great Goblin saw the blade that slew many Goblins beforehand in possession of Thorin. When the Great Goblin was killed, all the other Goblins with their Wargs followed Thorin's company to avenge their ruler, [[spoiler:[[FromBadToWorse and believed they were more of a threat when Smaug was killed and the dwarves' treasure was reclaimed, regardless of the fact that the dwarves, elves and men were not interested in sharing]]. The Goblins lost the battle of Five Armies to the [[EnemyMine allied dwarves, elves, men and Eagles]] despite managing to kill Thorin, Fili and Kili. [[Literature/TheLordOfTheRings Years later, they would get more revenge by wiping out the Moria dwarves, including Balin, Ori, and Oin]]]].
* ''Literature/NightfallSeries'': A villainous example – Tristan is completely devoted to Vladimir, so much that many call him the Prince’s puppy.
* Boxer, the horse in ''Literature/AnimalFarm''. "Napoleon is always right." Unfortunately, Napoleon didn't [[YouHaveOutlivedYourUsefulness return the sentiments]]... Particularly tragic because the reason Boxer outlived his use was he was working extra hard to please Napoleon.
* [[Franchise/StarWarsExpandedUniverse Mara Jade]] isn't the kind to give away her loyalty easily, but when she does, she'll defend whatever she chose with her life. She tends to be loyal to specific people rather than a large group; to Palpatine as an [[ProfessionalKiller Emperor's Hand]], to Talon Karrde as a smuggler, and to Luke and Ben as a Jedi, wife and [[MamaBear mother]].
** The ThreeAmigos ([[TheHero Luke,]] [[TheChick Leia]] and [[TheLancer Han]]) of the [[StarWars Original Trilogy]] qualify even better. It's what Palpatine used to tempt Luke to fall to TheDarkSide, and almost succeeded.
* ''Literature/TheDresdenFiles'': Harry Dresden and Thomas Raith, the first because he never had any family aside from his father who died when he was small, and Thomas because his family was so messed up that he always protected his siblings, and that was the attitude Lord Raith instilled in his family (as a method of control), [[spoiler:especially, his younger siblings, i.e. Harry and Inari]]. Family is important.
-->'''Harry:''' ''[in ''Proven Guilty'' when they are about to attack Arctis Tor and, having given a you-don't-have-to-come-with-me speech, his companions all step forward]'' I don't care whose DNA recombined with whose. When everything goes to hell, the people who stand by you without flinching--they are your family.
** In the later books, he develops this with Murphy too.
--->'''Murphy:''' [[spoiler:Don't you start taking the highway to Hell]]. Because I'm going to be right there with you. All the way.
** Molly to Harry. Harry's not too happy about this, given all of the questionable deeds she's done for his sake. Mab goes so far as to [[NotSoDifferent compare him]] to his old EvilMentor Justin.
* Gunner Ferik Jurgen is completely loyal to Commissar Literature/CiaphasCain, HERO OF THE IMPERIUM, who trusts him more than himself (because he [[HeroicSelfDeprecation "knows"]] [[FakeUltimateHero he isn't as trustworthy as people say]]). Jurgen will obey any order from Cain, no matter how crazy it sounds.
* Mary Ann Patten in ''Literature/TheCaptainsWife'' . Which is BasedOnATrueStory.
* Andrew [=LaFollet=] in ''Literature/HonorHarrington'' is the titular character's personal armsman, sworn to die for her service if necessary. [[spoiler: Despite Honor's trying to save him as the last surviving original armsman by having him guard her son, he dies saving his cousin and Honor's son and mother]]
** Not just Andrew, but ALL of her armsmen display this. It's a 100% volunteer service and they all joined as they feel they owe a personal debt to her.
** Then there's Horace Harkness's loyalty to Manticore. Caught, given a chance to surrender and or die, he switches sides. Then proceeds to manipulate his keepers until he can personally free his commander in a rather epic way.
* Jacopo to Dantes in ''Literature/TheCountOfMonteCristo'', as well as Haidee and Ali.
* Creator/LordByron wrote a poem dedicated to a beloved dog who died of rabies titled ''[[http://en.wikipedia.org/wiki/Epitaph_to_a_Dog Epitaph to a Dog]].'' The dog's unflinching love and loyalty are described in great detail:
-->''But the poor Dog, in life the firmest friend\\
The first to welcome, foremost to defend\\
Whose honest heart is still his Master’s own\\
Who labours, fights, lives, breathes for him alone''
* In ''Literature/{{Dune}}'', the servitors of the Atreides [[spoiler:except Yueh]] are loyal to their House. [[spoiler:And even Yueh took steps to ensure that Paul and Jessica would survive his betrayal.]] Duncan Idaho sacrifices himself to buy time for Paul and Jessica's escape, Gurney Halleck quickly renews his service to Paul when he discovers he is alive, and Thufir Hawat kills himself rather than follow through on orders from the Emperor to kill Paul.
-->'''Thufir:''' You see, your Majesty? See your traitor's needle? Did you think that I who swore my life to the Atreides would give them less now?
** The Atreides dukes are similarly loyal and protective toward their retainers. Paul Atreides is even willing to sacrifice his life to save the much, ''much'' older Hawat:
--->'''Paul:''' For I say to you, Thufir, that in payment for your years of service to my family you may now ask anything you wish of me. Anything at all. Do you need my life now, Thufir? It is yours.
*** And it's ironically the Atreides' ability to command this sort of fanatical loyalty which makes the Emperor nervous enough for his own throne to [[spoiler:assist the Harkonnens in their overthrow]] in the first place.
* ''Literature/TwentyThousandLeaguesUnderTheSea'': Exaggerated with Conseil, TheProfessor Aronnax's servant. He risks his life to save his employer not once, but twice in the novel. When Aronnax talks with Ned Land about the GreatEscape, Lampshaded when Conseil considers himself one with his master's decision.
-->"Your friend Conseil," the fine lad replied serenely, "has nothing to say for himself. He's a completely disinterested party on this question...He's in Master's employ, he thinks like Master, he speaks like Master, and much to his regret, he can't be counted on to form a majority. Only two persons face each other here: Master on one side, Ned Land on the other. That said, your friend Conseil is listening, and he's ready to keep score."
-->"I couldn't help smiling as Conseil wiped himself out of existence."
* In ''Literature/ASongOfIceAndFire'', Davos is forever loyal to King Stannis Baratheon, even after [[spoiler: losing four sons in Stannis's service]].
** Catelyn orders Brienne to bring Sansa back to her from King's Landing. By the time Brienne arrives, Sansa is no longer there, so Brienne starts searching for Sansa desperately, despite the dangers of the road [[spoiler:and the fact that Catelyn is already dead by the time, and there is no safe place Brienne could bring Sansa to anyway]].
** House Manderly is the only noble Andal House in the North. They were taken in long ago by the Starks and given the key port of White Harbor. They have repaid the debt with utter loyalty. ''The North Remembers.''
*** The entire North ([[spoiler:except for the Boltons and possibly the Karstarks, Ryswells and Dustins]]) exhibit this trope toward the Starks. The Northmen, both lords and smallfolk alike, are willing to march through blizzards, bone-chilling cold in a state of near starvation, or just keep on fighting even when all hope is faded, for the sake of the Starks. [[spoiler:The North's loyalty to the Stark family is the reason why King Stannis Baratheon wants to legitimize Lord Eddard Stark's [[HeroicBastard illegitimate son Jon Snow]] (who was openly raised by Eddard as his son alongside his trueborn offspring) so Stannis can win the North's support via a son of Eddard Stark -- Jon -- but Jon turns Stannis down for the sake of duty to the Night's Watch and out of loyalty to his siblings.]]
*** Special mention should also go to Greatjon Umber, who is one of Robb's staunchest supporters and is furious if anyone even insults Robb.
** The Kingsguard are ''supposed'' to be this in regard to the King of Westeros. Jaime Lannister is reviled as TheOathbreaker for betraying his vows, even though everyone knows that Aerys II was a [[TheCaligula madman]].
*** Of course, he keeps up the pattern by betraying the next king by sleeping with his wife. Said wife also happens to be [[{{Squick}} Jaime's twin sister]].
** Like the Northern Houses, the Vale Lords are completely loyal to House Arryn -- particularly to [[TheGoodChancellor Jon Arryn]] and, by proxy, to his son [[IllGirl Robert Arryn]].
* [[TheDreaded Luca Brasi]] from ''Literature/TheGodfather'' has this towards [[TheDon Vito]] [[TheChessmaster Corleone]]. In the backstory it is mentioned that during the [[MobWar Olive Oil War]] some mobsters tried to kill Vito and Luca proceeded to go on a RoaringRampageOfRevenge that ''only'' ended when Vito became well enough to call him off. However, this trait ultimately backfires on him when Vito has him pretend to leave the Corleone family to infiltrate a rival mafia family and they see right through it.
* Sancho Panza claims to be this for ''Literature/DonQuixote'', but there are limits for patience when in the service of a LordErrorProne who always manages to get himself and Sancho in an HumiliationConga [[OnceAnEpisode Once A Chapter]]. Several times in the book, Sancho considers leaving Don Quixote's service, but he is so fond of him he never does it.
-->"...if I were wise I should have left my master long ago; but this was my fate, this was my bad luck; I can't help it, I must follow him; we're from the same village, I've eaten his bread, I'm fond of him, I'm grateful, [[ItMakesSenseInContext he gave me his ass-colts]], and above all I'm faithful; so it's quite impossible for anything to separate us, [[NeverSayDie except the pickaxe and shovel]]."
* The first book of ''Literature/TheSwordOfTruth'' series is dealing with a ritual the BigBad uses to get into the world of the dead and back. It involves brainwashing a young boy into complete loyalty, killing him (by making him drink molten lead), and then using his spirit to travel to the underworld and back. As a case of taking the trope UpToEleven, the boy must remain loyal ''until the traveler returns''. In a later book, Richard uses this ritual as well, except he already had a spirit loyal enough to him since book one.
* ''Literature/SongAtDawn:'' According to Raoulf, all soldiers should have this for their liege lord.
-->'''Raoulf:''' She's just a woman. He's your liege Lord, my boy, and if it was you instead that he wanted, Viking fashion, why, you'd just have to bend over and take it.
* Lucy Pennykettle to David Rain in ''[[Literature/{{Dragons}} The Last Dragon Chronicles]]''.
* Dr. Watson to Literature/SherlockHolmes. He repeatedly risks his life to accompany Holmes, puts up with repeated cruel manipulations and deceptions from the man with little reaction except relief that Holmes is safe, and adamantly refuses to leave whenever Holmes suggests that what they're doing might be dangerous/illegal/insane and that Watson would be safer staying out of it. Once he even forces Holmes to take him along on a burglary, when Holmes is reluctant to risk Watson getting thrown in jail too if they're caught, by threatening to turn Holmes in himself. He doesn't only exhibit this loyalty towards Holmes, though--Watson also muses about being willing to die for Sir Henry Baskerville about three days after first meeting him, and vows to dedicate his life to searching for Mary Morstan's lost treasure equally quickly, even though it would put her far out of his league.
* In ''Literature/DangerousSpirits'', Konstantine retains his loyalty to the Tsars even a hundred years after his death during the Revolution.
* Giovanna from ''Literature/OfFearAndFaith'' inspires this in the soldiers under her command, and they strive to follow her example ([[HonorBeforeReason for better or worse]]).
* In ''Literature/SweetPiglet'', we have this with the piglet, after its master dies.
* The ''Literature/AgeOfFire'' series:
** Shadowcatch takes his oaths seriously (in fact, those who willingly break them are a bit of a BerserkButton to him). As such, when he pledges himself as Tyr [=RuGaard's=] bodyguard, he stays utterly loyal [[spoiler: even after [=RuGaard=] is ousted in a coup and exiled, following him into it. Years later, he says that he still considers [=RuGaard=] the only real Tyr]].
** There's also [=RuGaard's=] pet bats. They might be easily bribed with blood meals from other dragons, but they're ultimately loyal to their original benefactor. This is best shown [[spoiler:during the FinalBattle with [[BigBadDuumvirate Infamnia and Rayg]], who betrayed [=RuGaard=], [[NeverFoundTheBody seemingly to his death]]. The bats end up swarming the two en masse, with shouts of "Revenge for our Tyr!", contributing to their demise]]. [=AuRon=] comments on his brother's ability to inspire loyalty in others, and seems impressed by it.
* ''Literature/WolfHall'' portrays Thomas Cromwell as being very close to Cardinal Wolsey. After Wolsey is kicked out of his office and exiled north for failing to get Henry's marriage to Catharine of Aragon annulled, Cromwell spends most of his time trying to restore Wolsey to the King's good graces--unsuccessfully, and Wolsey dies on a journey back to a trial for treason. Cromwell often thinks about Wolsey and what he would do in a given situation and still refers to him as his "master". Later, when the King wants Anne Boleyn gone, Cromwell uses the opportunity to avenge Wolsey by having the five men who he deems most responsible convicted and executed alongside her.
* Peeta Mellark towards Katniss Everdeen in ''Literature/TheHungerGames''. Their mentor Haymitch notes after their first arena that there was no point in trying to save Peeta because he didn't want it - he wanted Katniss to win. [[spoiler:Even brainwashing (or "hijacking") designed to make him hate and fear Katniss, essentially turning him into a weapon against her, is able to change this for more than a few weeks or months at the most. This in comparison to every other person who has been subjected to this - Peeta is the ''only'' one who has been able to overcome it.]]
* Melanie Wilkes towards Scarlett O'Hara in ''Literature/GoneWithTheWind''. It doesn't matter what Scarlett does, what social norms she breaks, or how uncomfortable Melly might feel about some of these things. She is Team Scarlett 100% and she will cast aside people she has known and loved since childhood if they speak against Scarlett. She doesn't seem to notice that Scarlett for a long while despises her - they are sisters in law and family and to Melly that's that. Of course, it helps that Melly is the only one who was there and saw everything Scarlett suffered and all the sacrifices she made so that those in her household could have food, clothing and a roof over their heads.
* Spinnock Durav from ''Literature/MalazanBookOfTheFallen'' will do pretty much anything Rake asks him to, even if that means not acting on his newly discovered feelings for Salind, or having to fight [[spoiler: Kallor]] for a whole night straight.
* Giacomo, the protagonist of ''Literature/RebelGenius'', is revealed to be [[spoiler:a Tulpa, an artistic being of destruction]] near the end of the book. Instead of treating him coldly like they had before (though Aaminah had been friendly), his new friends (especially Savino, who is TheRival for Giacamo) decide that he's ultimately their friend, and they start [[spoiler:seeing Tulpa in a different light]].
* In ''Literature/TheSpiritThief'':
** Nico and Josef are insanely loyal to one another, to the point that either is perfectly willing to put the fate of the entire world on the line for the other's sake.
** For Miranda, her spirits will openly defy their all-powerful goddess.
* ''Literature/TheWanderingInn'': The Seven never stopped being loyal to Flos, the King of Destruction, even when he lost all motivation, and for 10 years just sat on his throne, letting his kingdom slowly waste away.

[[folder:Live Action TV]]
* ''Series/TwentyFour'': Chloe O'Brian towards Jack Bauer.
* In ''Series/TheAlmightyJohnsons'', Stacy is the goddess Fulla, handmaiden to the goddess Frigg. So when she meets Frigg, not only is she the only one who is one hundred percent sure of who she is (everyone else can immediately tell she's a powerful goddess, but everything else is up in the air), she's also perfectly willing to do anything for her despite having known her for less than a day. Example: Stacy hates taking orders, but the episode after Frigg is introduced, she's seen helping her with her hair without a word of complaint. [[spoiler:Unfortunately, that's not Frigg. Whoops]].
* ''Series/AgentsOfSHIELD'': Nearly everyone under Phil Coulson's command is willing to follow him to the ends of the Earth--literally, on occasion. Special note goes to Melinda May, the TeamMom to Coulson's TeamDad. When Coulson refuses to join HYDRA, the Clairvoyant doesn't even bother making the same offer to May.
-->'''The Clairvoyant:''' I know you'd follow him to the grave so...
* ''Series/TheATeam'': So very much. Their loyalty to one another is so strong that in the beginning of Season 5, [[spoiler:Hannibal, Face, and B.A. are willing to face the firing squad so Murdock won't have to. Don't worry. They all make it out just fine]]. And in the second season episode "[[Recap/TheATeamS2E23CurtainCall Curtain Call]]"', Face makes it quite clear that he is willing to risk capture and being sent to prison in order to get the proper medical supplies to save Murdock's life. And those are just two examples. The whole show is filled with moments like those.
* ''Series/BabylonFive'':
** Lennier to Delenn, Vir to Londo.
** Also Ranger Marcus Cole to Delenn, who once fought a DuelToTheDeath against a rival Warrior who wanted to assassinate her. The fact that she could inspire such loyalty, particularly in a human, convinced her rival that she deserved leadership of the Rangers.
* ''Series/BreakingBad'': This trope is {{lampshaded}} with near OnceAnEpisode regularity regarding Walt and Jesse. It's a rather interesting case, as they're frequently at each other's throats, sometimes just because they're mad at one another, and sometimes much more seriously than that. Mike mentions it more than others as he is fond of Jesse's loyalty, but loathes who the loyalty is directed at. Towards the end of the half-fifth season, [[spoiler:Jesse breaks it when he finally realizes [[ProtagonistJourneyToVillain how far Walt has gone and]] and he, himself, becomes TheAtoner]].
* ''Series/BurnNotice'': Michael, Sam and Fiona (and later Jesse) go to rather extreme lengths to look out for each other. Sam and Fiona start off pretty rocky, and Jesse's loyalty wavers when he finds out the truth of who burned him, but ultimately, they're all willing to risk their lives to help each other.
* ''Series/{{Chuck}}'': Loyalty is a common theme, but perhaps most notable in Morgan. He repeatedly risks life and limb for the gang without a moment's hesitation. He's so loyal and daring that even [[spoiler: [[ColonelBadass Casey]]]] is impressed.
* ''Series/{{Daredevil 2015}}'': [[TheDragon James Wesley]] to [[ComicBook/TheKingpin Wilson Fisk]]. [[VillainousFriendship His loyalty extends beyond even the business aspect of it all]]. He attempts to help his boss woo the woman that he's infatuated with and seems only want to make sure that he's as happy as possible. At one point, he even breaks Fisk's explicit orders that he be left alone during an internal crisis, in order to bring Vanessa in so that she can help him through it.
* ''Series/DoctorWho'':
** Rory Williams. Rather than jumping forward in time with the Doctor, quick and easy, he chooses to stay behind and guard the Pandorica for 2,000 years (knowing that he will be conscious the whole time) to ensure that Amy is safe locked inside of it, despite the Doctor assuring him that Amy will be fine and warning him that the wait will drive him insane. Not even a little inconvenience like [[RetGone being erased from history]] is going to keep him away from Amy.
** Martha Jones, a loyal friend if there ever was one, endures months of mistreatment and racist harrassment, and later, a full year of walking a dystopian wasteland all by herself, for the sake of the Doctor's safety.
** If anything is remotely possible within the laws of physics, the Doctor is probably willing to do anything in his power to achieve it if Clara Oswald asked it of him. An interesting example in that this is in large parts born out of gratitude for multiple significant incidents where she went to great lengths to support ''him'', and that you wouldn't guess it at all by the way they usually argue, boss each other around, and address each other with very little courtesy. It is only after a major personal tragedy drives her to a crass breach of trust that the full extent of his devotion becomes clear:
---> "Do you think I care for you so little that betraying me would make a difference?"
*** Cranked up to eleven in Series 9 when not only does Clara exhibit dangerously undying loyalty towards the Doctor (to the point of starting to believe him invincible and, by extension, herself), but when she is KilledOffForReal, the Doctor spends ''billions'' of years on a self-torturing BatmanGambit to get her back.
* ''Series/{{Firefly}}'':
** [[TheChampion Dr. Simon Tam]] is devoted to being TheCaretaker and, when required, the PapaWolf to his [[TheWoobie disturbed little sister River.]] Naturally, she responds in the BigDamnMovie. In his case, he usually leads, because he is, of course, the big brother. He is, like [[Literature/TheLordOfTheRings Sam Gamgee,]] very much a {{Determinator}}.
** Effectively he [[HeroicSpirit takes on]] the traditional jobs of [[BigBrotherInstinct Brother]], [[DaddysGirl Father]], [[DotingParent Mother]], [[TheMedic Doctor]], [[TheCaretaker Therapist]], and [[PapaWolf Bodyguard]] [[{{Determinator}} all at once, probably for the rest of his life]], all the while [[NobleFugitive fleeing from the law]]. All [[HeroicSacrifice for Mei-Mei]].
--->"Mei-Mei, all I have is right here."
*** And he gives up a guaranteed life of safety, prestige, power, luxury and riches to do it.
** River herself does this, as well.
--->[[NowLetMeCarryYou "No. You take care of me, Simon. You've always taken care of me.]] [[YouShallNotPass My turn]]."
** And Mal. Because if you turn on '''any''' of his crew, ''[[ThrownOutTheAirlock you turn on him]]''.
** Zoe's characterization is primarily based on her loyalty to Mal. The main source of tension in her marriage is that she seems more devoted to Mal than to her husband.
* ''Series/TheFlash2014'':
** Cisco and Caitlin remained loyal to Dr. Wells even after the particle accelerator explosion. This all changed when they discover [[spoiler: he was in fact Eobard Thawne, the Reverse-Flash]].
** Grodd remains loyal to his "father" Eobard Thawne and goes ballistic when he finds someone impersonating him.
** King Shark is perhaps the only meta of Earth-2 whose loyalty to Zoom is genuine. Even after spending weeks in prison, all he talks about is how Zoom wants the Flash dead.
* The whole ''Series/{{Friends}}'' gang. They'll defend and support each other against anything and anyone, and several times drop outsiders for the sake of the gang. Joey is probably the most stand-out example.
* ''Series/{{Fringe}}'':
** Most of the team [[spoiler: (actually, both teams)]] towards each other, but especially the core family of Peter, Walter, and Olivia.
** In later seasons, Lincoln Lee [[spoiler: in both universes]] comes to be one of the most loyal characters in the show.
** Also, heartbreakingly, [[spoiler: Nina]] towards the end of Season 5.
* ''Series/GameOfThrones'':
** While House Tyrell [[spoiler: joined the Lannisters out of a desire to gain more political power, Ser Loras Tyrell himself only wanted to avenge Lord Renly Baratheon's murder. Commanding a cavalry charge while wearing his deceased lover's armour is quite a GrandRomanticGesture, as it was Loras' way of honouring the vow he had made to Renly in Season 1]].
** [[TheLancer Davos]] [[NumberTwo Seaworth]] towards [[BrutalHonesty Stannis]] [[NoSocialSkills Baratheon]], so very much. He doesn't hold any grudge towards Stannis for cutting off the top halves of his fingers on one hand (considering it a just punishment), and serves him as a highly competent adviser who makes up for Stannis's lack of social skills. Despite his misgivings about waging war against enemies that outnumber them, he remains loyal to Stannis and will follow wherever he leads. Stannis, for his part, is well aware of this, and rewards Davos by appointing him as his Hand of the King. The two are also basically HeterosexualLifePartners. His loyalty is frequently displayed in-universe.
*** His loyalty despite Stannis cutting off his fingers is lampshaded in-universe by Salladhor. Davos explains it's because Stannis raised him up to nobility, which ensured Matthos a future Davos could never have dreamed of providing for.
---> '''Salladhor Saan:''' You Westerosi are funny people. Man cuts off your fingers, you fall in love with him!
*** A more subtle instance of this happens when Davos is stranded on an islet in Blackwater Bay after the destruction of Stannis's fleet. When a ship sees him and sends out a boat to investigate, they ask him which king he serves. Davos knows fully well that they might well be serving Joffrey, and he doesn't even know if Stannis is alive. He still answers "Stannis Baratheon".
*** When he's thrown in a dungeon under charges of treason, Davos remains loyal to Stannis and when Shireen asks him if he really is a traitor, he accepts that he is. Furthermore emphasised in "Mhysa", when Stannis prepares to sentence him to death for letting Gendry escape, Davos informs him that he'll fully accept that if it's his will, but since he's not removed him as Hand of the King yet, then as Hand, he'd advise Stannis that it would be a mistake.
** Following Stannis' death, Davos has now shifted it to Jon Snow as he is one of the many among the crowd to proclaim him King in the North.
** After [[HeroicBastard Jon]] [[TheStoic Snow]] learns [[LovableCoward Samwell]] [[FatBestFriend Tarly's]] rough backstory, he [[{{Protectorate}} takes Sam under his protection]] and sticks up for him against Ser Alliser and some other bullies in the Night's Watch. In return, Sam develops this for Jon, and is able to overcome his cowardly nature several times for Jon's sake. A great example is when, in Season 5, [[spoiler:he nominates Jon to run against Ser Alliser as Lord Commander of the Night's Watch--despite knowing that Alliser will make Sam's life hell for doing this if Alliser wins anyway--because Sam knows that Alliser will make ''Jon's'' life hell otherwise, and that Jon deserves it more but is too honorable to nominate himself]].
** Despite Tyrion's fall from power, his squire, Podrick Payne still remains loyal to him, even more so than Bronn, as he's not even paid by Tyrion. He even returns back to Tyrion the fee the latter paid Pod's whores, despite Tyrion not expecting it back. In season 4, Tyrion is accused off Joffrey's death but Pod refuses to betray or abandon him even after [[spoiler:Tyrion himself]] warns him that remaining loyal to him will likely lead to torture and/or death. [[spoiler:Tyrion has no choice but to ''[[ShooTheDog order]]'' Podrick to leave his service and King's Landing since he does not want Podrick to die for him]]. Tyrion's parting words to him: "There has never lived a more loyal squire."
** Brienne is a double example and this almost leads to disaster. She remains dedicated to King Renly, even after his death, swearing to avenge him and becoming furious and forceful when Jaime insults his homosexuality one time too many, forcefully grabbing his head and looking like she wants to ''kill'' him. Her vow to bring the prisoner to King's Landing alive is the only thing that prevented her from carrying out her wish. She still refers to Renly as her king in "Two Swords." At the same time, Brienne swore loyalty to Catelyn Stark directly after Renly's death and vowed to retrieve her daughters and protect her. She points out to Jaime "I dont serve House Stark, I serve Lady Catelyn". Later, she still insists on bringing Sansa and Arya to safety after Catelyn's death.
** Even though Daenerys has already purchased the unquestioning obedience of the Unsullied, when she frees them she earns the vast majority's loyalty even beyond their Unsullied conditioning.
** This is the job description of a Dothraki bloodrider. If their ''khal'' dies, they are to avenge his death, escort his ''khaleesi'' to Vaes Dothrak, and then join their ''khal'' in death.
** The people of the North, both the high lords and the smallfolk have this for their Stark overlords, so much that they will refuse to follow anyone else even on pain of death. This is a bit of a deconstruction as no one in the North will ally themselves with one of the few people who can and is willing to help them because he is both of the south and not a Stark, even if its in their best interest. This dates back to even Robert's Rebellion as Stannis Baratheon notes that even with the much loved Ned Stark, the future and charismatic king Robert had trouble controlling them. Tragically season 6 reveals Robb's actions in the War of Five Kings have broken this, with many in the North blaming him and his house for all they've lost, especially at the Red Wedding. Not only have the Karstarks and Boltons betrayed them, but the Umbers use Jon's actions as Lord Commander (letting the Wildlings through the Wall) to side with the Boltons, the Glovers refuse to aid Sansa and Jon in taking back Winterfell and the Mormonts refuse to give their help until heavily persuaded. However, by the end of season 6, the bonds of loyalty are seemingly restored as the Starks claim victory over the Boltons and many Northern Houses are ashamed of not standing by them when Jon and Sansa first called for aid which leads them to not only re-declare for House Stark, but also crown Jon Snow the new King in the North. Specific examples of Northerners with Undying Loyalty to the Starks include:
*** Even though maesters are supposed to serve the realm and no particular family, it's clear Luwin is more loyal to the Starks. Even when advising Theon, he's attempting to protect Bran and Rickon.
*** Osha to the Stark boys in particular, but she reveals in "The Rains of Castermere" that she has this loyalty to the entire house due to their taking her in despite having no reason to do so.
*** Rodrik Cassel. This results in his death and he seems to literally fall under this trope since he tells Bran that he'll be seeing Ned soon, implying that he intends to serve Lord Stark even in the afterlife.
*** Septa Mordane to the Starks and Sansa, hence her HeroicSacrifice.
*** Nymeria to Arya. She's forced to leave her, but is never too far.
*** House Reed to House Stark, moreso than even other Northern Houses. Even with the Starks defeated and Winterfell burned, the Reed children continue to follow and protect Bran Stark as his brother Robb's heir (and to guide him to his magical destiny beyond the Wall).
*** Howland Reed to Eddard Stark. He was one of Eddard's personal companions during Robert's Rebellion.
*** House Mormont. Lyanna Mormont lets Stannis know in no uncertain terms that House Mormont will only follow House Stark telling him "House Bolton knows no king but the King in the North, whose name is Stark". When Jon and Sansa call upon her to aid them against the Boltons, Lyanna eventually decides to uphold their millennia old alliance and fight with them once again. Once the Stark alliance reclaims Winterfell, her scathing words shame all the other northern lords, many of which did not answer the Starks' call, and then she becomes Jon's kingmaker. Despite being unable to devote not even a hundred troops to the Battle of the Bastards, she turned out to be by far the most valuable ally that Jon and Sansa recruited.
---> '''Lyanna:''' House Mormont has kept faith with House Stark for a thousand years. We will not break faith today.
*** House Glover, until Lord Robett's reign, as Robett refuses to be dragged into a war he doesn't believe can be won. Following the restoration of House Stark after the Second Battle of Winterfell, Lord Robett reaffirms their loyalty.
*** House Cerwyn stand behind the Starks when the Boltons take the North. Unfortunately, this causes the death of the entire House except one heir, Cley Cerwyn, who only kneeled to the Boltons under direct threat. When that passes, he's a proud bannerman to House Stark again.
*** Small though they are, Houses Mazin and Hornwood still join the remnants of House Stark.
** Ramsey insists that his dogs are loyal to him, but this is proven untrue when they proceed to feast on him in "Battle of the Bastards" after being starved for a week by him.
** One of Meera's dominant traits. She protects her brother and Bran with her life, the latter even in the face of certain, grisly death at the hands of an army of wights, and never so much as considers wavering in it.
** Kevan Lannister follows the King's commands, no matter what they are.
** Varys. At least that's how he puts it, describing what appears to be an extreme ChronicBackstabbingDisorder as being constantly loyal to the regular people who will suffer because of the high-ranking person he's just turned against.
* ''Series/GossipGirl'': Dorota is always loyal to Blair on , no matter what happens. Chuck Bass is also incredibly loyal to those he cares about.
* ''Series/{{Gotham}}'': By the end of the first season, Jim Gordon has earned this from Harvey Bullock, a [[KnightInSourArmor knight whose armor is so sour]] he needs a couple of drinks in the morning just to sober up.
* ''Series/InspectorLynley'': DI Thomas Lynley and his partner DS Barbara Havers, to each other. Any attempt to turn them against each other ''will'' fail.
* ''Series/KaizokuSentaiGokaiger'':
** The crew are amazingly loyal to Captain Marvelous, but especially the first mate, Joe Gibken/Gokai Blue.
** Later in the series this is proven to be a trait of [[spoiler: [[Series/ChoujinSentaiJetman Gai Yuuki]]]], who keeps his former teammates from getting involved in further fighting, [[spoiler: [[DeadAllAlong despite not even being alive]]]].
* ''Series/LawAndOrder'': The partnered detectives on these shows frequently exhibit this toward each other, although Goren and Eames on ''[[Series/LawAndOrderCriminalIntent Criminal Intent]]'' are perhaps the franchise's TropeCodifier. Eames even went so far as to [[spoiler: resign from the force after Goren was fired in the season 9 opener]].
* ''Series/{{Lexx}}'': Kai is a dead assassin who has been reanimated. He has no emotions and no motives, but for some reason, he always sets out to save Stan and Xev.
* ''Series/LogansRun'': Rem: In the first episode of the TV series, Logan and Jessica meet Rem, an android. He helps them escape from other androids, then is completely loyal to them for the rest of the series, although he has no reason to do so, even putting himself at risk of being destroyed several times to save them, sometimes harming other humans in the process. He's not programmed to do this. He just does it.
* ''Series/MarriedWithChildren'': Al Bundy has this toward his wife Peggy, even if he hates the marriage with a passion and wish for it to be undone; any time another woman offer herself to him, he'll (grudgingly) reject the offer in respect to his wife. Sure, he'll cry afterward but you've got to give him credit for the loyalty he shows to something he always says he hates with every fiber in his body.
* ''Series/TheMentalist'': Lisbon towards her entire team - but especially towards Jane. For him she's blackmailed one of her closest friends, blackmailed her ''boss's boss'', punched a robber in order to get his case thrown out of court, gotten locked in a box, and repeatedly gotten suspended from the job that is basically her whole life. Not to mention six months of anger management classes.
* ''Series/{{Merlin 2008}}'':
** Merlin to his loved ones, particularly Arthur, Guinevere, Morgana (before her FaceHeelTurn) and Gaius.
** No matter what happens, he always stands by Arthur, and by extension albeit very reluctantly, Uther.
** Lancelot to Gwen and the Knights to Arthur. Arthur would be completely ''stupid'' not to include him in the Knights of the Round Table.
** Against all legendary expectations, Guinevere to Arthur. Morgana had to resort to enchantments to force her into cheating on him with Lancelot. Even after Arthur banishes her from Camelot after believing her unfaithful, she continues to wear her engagement ring around her neck, and comes to his aid in his hour of need.
* ''Series/MillionYenWomen'': Shin's publicist Seiji stands by him despite his lack of success as an author, and blames said lack of success on a failure to do his own job properly.
* ''Series/{{NCIS}}'':
** Gibbs in has this toward his team. Abby undoubtedly does too, as she is just that kind of person, but has fewer chances to show it spectacularly.
** When Ziva is accused of a non-sanctioned assassination of a defected Syrian official in Witness Protection the whole team forms an extra-legal "conspiracy" to rescue her.
** [=McGee=] risks his career in another episode to [[BigBrotherInstinct save his sister]].
--->'''[=McGee=]'s Sister:''' But he loves NCIS...
--->'''Gibbs:''' Evidently he loves you more.
** Tony to Gibbs. He refused the chance to a promotion in a location of a lifetime on the knowledge that another promotion wasn't going to come up again anytime soon.
* ''Series/{{Nikita}}'':
** [[EliteMooks The Guardians]], along with [[TheBrute Roan]], are completely loyal to [[BigBad Percy]], and remain so even after [[GovernmentConspiracy Oversight]] [[spoiler: locks him up]] at the beginning of Season 2, [[spoiler: eventually helping him escape]].
** Michael, when he was TheDragon, also qualified, remaining loyal to Percy despite his misgivings about the latter's methods. That is, until he discovered [[spoiler: that Percy was behind the murder of his family]], which is what prompted his HeelFaceTurn.
* ''Series/OrphanBlack'': Foster siblings Sarah Manning and Felix Dawkins are very loyal to one another, mostly to Felix's detriment.
* ''Series/PersonOfInterest'': Reese towards Finch.
--> '''Reese''': Keep yourself alive, Harold. I'll be coming for you.
* ''Series/PrisonBreak'': Linc and Michael.
* ''Series/{{Revolution}}'': A number of Monroe militia soldiers display this toward Sebastian Monroe. However, it seems to be mostly due to fear rather than an actual loyalty, considering how foolish and deranged Monroe is. Still, Jeremy Baker, one of his oldest friends stuck with him in "[[Recap/RevolutionS1E17TheLongestDay The Longest Day]]". [[spoiler: When Monroe is about to have Baker executed out of paranoia, Baker gives him a speech about how Miles Matheson and Tom Neville betrayed Monroe because Monroe made them do so, Baker stuck with him through it all because he thought they were making a better world, Monroe will be all alone when he conquers the continent, and that Baker wouldn't wish that on his worst enemy, let alone his friend]].
* ''Series/{{Rome}}'': Vorenus. Once he swears fidelity to a cause or a person he will remain loyal to the end. Or as Octavian puts it, "''The man turns loyalty into a vice.''"
* ''Series/TerminatorTheSarahConnorChronicles'': [[RobotGirl Cameron]] is completely loyal to John Connor, and perfectly willing to be destroyed to protect him, to the point that she [[spoiler: implants a bomb in her head and gives the detonator to John]] in case she "goes bad." This is juxtaposed with a termination protocol that Skynet hardwired into her to kill John Connor specifically, which activates when she takes severe damage at the start of the series' second season. She is eventually able to override this protocol, but her fears that the damage she took will make her hostile again form a major part of her internal conflict over the series.
* ''Series/{{Scrubs}}'': JD towards Dr. Cox, one of the most prominent hallmarks of their relationship, especially whenever Cox is pitted against an outsider (or Kelso).
* ''Series/{{Sherlock}}'': [[HeteroSexualLifePartners John Watson.]] He refused to believe that [[LivingEmotionalCrutch his best friend]] was a fraud, [[spoiler: even when ''[[TearJerker Sherlock himself]]''[[note]]under duress from [[BigBad Moriarty,]] [[TearJerker who'd threatened to kill John and everyone else Sherlock cared about]][[/note]] [[TearJerker was telling him so before jumping off a rooftop to his]] [[FakingTheDead "death"]].]]
** [[AllOfTheOtherReindeer Sherlock himself]] should count for something, which proves it works both ways. [[spoiler:He jumped to keep [[FriendlessBackground the select few he cared about safe,]] saved [[LivingEmotionalCrutch John's]] [[CrowningMomentOfAwesome life by physically getting into and pulling him out of a fire,]] [[ThePowerOfLove stopped himself from being clinically dead since he thought John was in danger]], [[WhatAnIdiot and even killed]] [[BigBad Magnussen]] [[WhatAnIdiot (thus ending his career as a detective and possibly his life with the mission he was assigned)]] so [[HappilyMarried John could be happy with]] Mary]]. [[HeartwarmingMoments Awww. How sweet.]]
** [[PregnantBadass Mary]] too. She said that, even though she was an assassin, she didn't want her relationship with John to be ruined, and wanted to prevent that from happening. [[FridgeBrilliance You know, there's probably a reason why she should trust Sherlock. John trusts his friend to look out for Mary, so.....yeah. Wouldn't it make sense for her to trust Sherlock as well? Most likely.]]
** Molly too. She helped Sherlock fake his death for [[CoolBigBro John,]] [[TeamMom Mrs. Hudson]] and [[FriendOnTheForce Lestrade,]] but John especially, since she ''knows'' how important [[LivingEmotionalCrutch John]] is to Sherlock. Oh, and like Lestrade and John, didn't believe Sherlock was a fraud.
** Also, Sherlock and John ''did'' [[BigBrotherInstinct bust each other out of kooky situations.]]
** And, even though it was a risky case, [[ScrewtheRulesImDoingWhatsRight John was willing to betray the British government]] for [[BadassAdorable Mary.]]
** And Lestrade refused to believe Sherlock was a fraud as well.
** Mycroft, too, apparently, to Sherlock. He wanted to see if John was loyal to Sherlock, and not a spy for Moran, or Moriarty. He ''did'' interrogate John, and capture him, [[CrowningMomentOfHeartwarming which leads to John leaving Mycroft for Sherlock's sake.]]
** Since John is a doctor, he's most likely this for the human race.
* ''Series/{{Smallville}}'':
** He only appeared in six episodes, but [[CorruptCorporateExecutive Regan Matthews]] was characterized by his complete and undying loyalty to ComicBook/LexLuthor.
** [[MissionControl Chloe Sullivan]] may be PlatonicLifePartners with Clark Kent, but she demonstrated this more than once.
--->'''Chloe:''' I'd never tell anyone [about his secret]. I'd die before I'd ever betray you.
* ''Series/StargateSG1'': Samantha Carter would walk through fire for Jack O'Neill. Jack O'Neill "would rather die than lose Carter". And of course, SG-1 "is a team. No one else can begin to understand what that really means".
* ''Series/StargateAtlantis'': Like the example above, Stargate Atlantis's command team will risk anything and everything for each other and the city. Particularly John Sheppard and Elizabeth Weir who make it clear they won't lead the city with anyone else but each other: John will risk his neck defying his military commanders to support her and she'll call on every resource she has to protect him from their superiors.
* ''Franchise/StarTrek'':
** ''Series/StarTrekTheOriginalSeries'': The crew of the ''Enterprise''. This has three major variations: [[HeterosexualLifePartners Kirk]] and [[HoYay Spock's]] loyalty to each other, [[PowerTrio Kirk, Spock and [=McCoy=]'s]] loyalty to each other, and [[TrueCompanions the whole crew's]] loyalty to each other. It only gets more blatant the more films you watch.
** ''Series/StarTrekTheNextGeneration'': Fast forward a century from Kirk and Spock, and you have Picard and his crew. Any of them would lay down their life without hesitation for each other.
** Hell, [[Series/StarTrekDeepSpaceNine the]] [[Series/StarTrekVoyager other]] [[Series/StarTrekEnterprise spinoffs]] also feature crews who'd do anything for each other.
** ''Series/StarTrekDeepSpaceNine'' features a dark variation in the form of the [[AffablyEvil Vorta]] and the [[ProudWarriorRaceGuy Jem'Hadar]], who are genetically programmed to be unquestioningly loyal to the [[AGodAmI Founders]]. It's to the point that if the Jem'Hadar are ordered to commit mass suicide or allow themselves to be killed, they will do so, simply because it's "the order of things."
* ''Series/{{Supernatural}}'':
** The Winchester boys take the "undying" part ''literally''.
** This is Meg's defining character trait and possibly the only reason she's been able to slide so far into [[SociopathicHero heroic sociopath]] territory, despite committing numerous atrocities completely un-apologetically and being Lucifer's staunchest supporter. At one point, she gives Dean a speech about why she didn't sell them out, ending with the line: "I'm talking cause, douchebag, as in reason to get up in the morning".
** Since the show is basically about family relationships, this trait is fairly common. Other characters who exhibit strong tendencies towards loyalty include John, Bobby, Cas (before and after the civil war lead to the complete breakdown of his moral code), Balthazar (towards Cas), Gabriel (towards Lucifer and Michel), Rufus (towards his dead wife and Bobby), Ellen, and Jo. The MonsterOfTheWeek episodes frequently feature humans and monsters who readily sacrifice their lives or hang around after death in order to protect their loved ones.
*** Castiel's loyalty to Dean is so strong that when Naomi attempted to brainwash him into killing Dean, she had to force him to [[NightmareFuel kill hundreds of realistic facsimiles]] in order for the brainwashing to take--[[spoiler:[[ThePowerOfLove and it still didn't hold]]]]!
* In ''Series/TheThickOfIt'', a series where every other professional alliance and relationship is completely destroyed at least once, Sam stays on as Malcolm's PA for the entirety of the show's eight-year run.
* ''Series/TheWestWing'':
** The White House senior staff are strongly characterized by their devout, unshakable loyalty to President Bartlet ([[AFatherToHisMen who is similarly loyal to them, freely risking political capital rather than throw members of his staff under the bus]]), occasionally to the point of MyMasterRightOrWrong. However, they are also [[TrueCompanions similarly protective of each other]], putting their loyalty to their fellow staffers [[HonorBeforeReason before morality or reason]], comparing their relationships to [[ThickerThanWater family ties]].
** Special note must be taken of Charlie Young and his utter devotion to the President. How strong is this man's loyalty to his boss? The Secret Service cannot keep him away from President Barlett during a White House lockdown. And in the episode "Two Cathedrals", Charlie forgoes wearing a raincoat out into a hurricane's bow, just because the president chooses not to wear one.
* As in the book, Thomas Cromwell in ''Series/WolfHall'' is Cardinal Wolsey's man. They gain a quick affinity when Cromwell confesses his origins as the son of a Putney smith, and Wolsey the butcher's son is delighted to find another clever lowborn man in his world of {{Upper Class Twits}}. After Wolsey's death in disgrace and the celebratory masque thrown by those who brought him down, Cromwell tells his friend George Cavendish not to pray God for vengeance; he'll take it in hand. The show makes his hatred for Wolsey's enemies much more explicit; Cromwell hardly looks at them without flashing back to watching them laugh backstage.
* ''Series/TheXFiles'': It doesn't seem to matter what you throw at them, nothing so far discovered can break Mulder and Scully apart for more than a few hours - and even then, they just rebound with a tighter bond than before.

* The Music/{{Vocaloid}} song [[http://www.youtube.com/watch?v=NwnyPIbt1BA Servant of Evil]] is a companion song to [[http://www.youtube.com/watch?v=q46Osg9C4pA Daughter of Evil]] tells of the loyalty a servant has to his twin sister, whose cruel and evil acts led to the destruction of her kingdom. The brother, despite being a good man, follows her into evil willingly, even going so far as to murder the woman he loved by her order. In the end, when the sister's castle was about to fall to an army after her head, the brother switches places with her, allowing himself to be executed in her place.
** *VOiCE is a pretty upbeat song about a robot and his undying loyalty to his master (played by Hatsune Miku) who was taken away from him because of a war. Even till his last breath, he still protects his master's house, hoping to see her one more time.
* Bianca Ryan's song "I Will" is about the loyalty of the singer to the object of her affection and her support for him no matter what.
-->''I will come running to you''
-->''Nothing I wouldn't do.''
-->''I will never desert you, hurt you''
-->''I want you to know''.
* "I'll Stand by You" by The Pretenders (and other artists) promises love and commitment no matter the mood and circumstances of the person to whom it is addressed.
* Rick Astley is [[RickRoll never gonna give you up, never gonna let you down]]...
* Music/HeatherAlexander summed up the core of what every pet owner sees in [[LoyalAnimalCompanion their friend's]] eyes in "[[http://www.youtube.com/watch?v=Lx0ap6PBHac&list=PL-vqfuntBkU4qeN37YvabisSpsO8emVWk Familiar's Promise]]".
-->If it's courage you seek, I am yours to command.
-->I don't outwardly speak, but I still understand.
-->Through your joy and your strife, I'll attend to any task;
-->I will lay down my life; all you need do is ask.

-->Lay your hand on my head
-->As the firelight dies,
-->And believe what I've said,
-->For this love never lies.

* The speaker of "Quiet Little Voices" by We Were Promised Jetpacks is this in full:
-->In any which direction, call me
-->I will run for you, I'll come for you
-->I'll die for you, I'll come for you
* Music/DeathCabForCutie's "I Will Follow You Into the Dark".
-->''If Heaven and Hell decide that they both are satisfied\\
Illuminate the "No"s on their "Vacancy" signs\\
If there's no one beside you when your soul embarks\\
[[TitleDrop Then I will follow you into the dark]]''

* Hanuman, as described in the ''Literature/{{Ramayana}}'' is completely devoted to Rama, to the point he swears he will live as long as Rama's name is spoken and revered, ''effectively becoming immortal''.
* ''Literature/TheShahnameh'' When Manijeh's father, Afrasiab learns of her relationship with the Persian warrior Bijan, she is degraded, roughed up, kicked out of her home and all her possessions are confiscated. The princess goes door to door each day begging for food so she can keep Bijan, who's chained at the bottom of a hole sealed by a giant boulder alive.
* Penelope to Odysseus in ''Literature/TheOdyssey''.
** For that matter, Odysseus' dog in the same tale. The dog waited patiently for twenty years in abject neglect for his master to return, and when Odysseus does (albeit incognito), the dog recognizes him enough to wag its tail, then dies.
* Achates to Aeneas in ''Literature/TheAeneid''.
* Hagen to Gunther in ''Literature/{{Nibelungenlied}}''.

* In ''[[Pinball/WHODunnit WHO dunnit]]'', Butler has this for his employer, Victoria, despite her terrible treatment of him and her BlackWidow tendencies. [[spoiler:Justified, as he is secretly her father, and treasures her as his only surviving link to her late mother]].

* ''Literature/TheBattleOfMaldon'':
-->Here lies our [[MagneticHero leader]]\\
In the dust of his [[WarriorPrince greatness]]\\
Who leaves him now be [[HonorBeforeReason shamed forever]]\\
I who am [[BadassGrandpa old]] will not leave this [[LastStand battle]]\\
But will lie by his side in the dust with my [[MyMasterRightOrWrong Master]]

* Wrestling/AJStyles was known for his loyalty to Wrestling/{{TNA}}, having been one of the few constants in the ever-changing company. However, their continued incompetence and misuse of his talents and those of his coworkers caused him to leave for good in December 2013. That was taken as a sign by many fans that TNA was going down the drain. [[TheParagonAlwaysRebels When AJ left]], Bad Influence (Wrestling/ChristopherDaniels and Wrestling/FrankieKazarian) and Wrestling/SamoaJoe followed him, along with the ''founder'' of TNA, Wrestling/JeffJarrett. Then Wrestling/BobbyRoode, and Eric Young left. Leaving Abyss as the only original who refused to jump ship, even if it was sinking. Though Wrestling/JamesStorm left for monetary reasons, he came back to TNA when they offered him a deal no other company was willing to beat.
* For most of 2004, when ROH happened to be going through its worst crisis, the Briscoes were not there, as Mark Briscoe was injured in a motorcycle accident and despite being considered the better wrestler ROH and other companies like Wrestling/{{CZW}} were willing to push solo, Jay refused to return to pro wrestling without his brother. This resulted in him only taking bookings for three months of the year and was the ''only'' time he voluntarily took an extended leave from ROH, a company he otherwise wrestled for his entire adult life.
* Wrestling/RingOfHonor formed the Decade, comprising of Wrestling/JimmyJacobs, BJ Whitmer, and Wrestling/RoderickStrong, all three of whom had been with the company for ten years. They targeted wrestlers who left the company for WWE and/or TNA and then came back for whatever reason, more-or-less ''invoking'' this trope.
* As for the Wrestling/{{WWE}} itself, today the only ones who can truly count are Wrestling/TheUndertaker (who still wrestles whenever he can despite his broken down body), Wrestling/{{Kane}}, and Wrestling/JohnCena (he stated that he would only ever wrestle for the WWE). The rest who have stuck for the WWE for so long are retired or got KickedUpstairs.

[[folder:Tabletop Games]]
* In ''TabletopGame/{{Gurps}}'' this is called "Sense of Duty".
* ''TabletopGame/LegendOfTheFiveRings'' gives us the story of the [[MagnificentBastard Scorpion Clan Champion]] Bayushi Ujiro and his bodyguard Shunsen. Ujiro issued a challenge to the other Clan champions to determine which clan best understood the concept of loyalty. The challenge involved all the champions and their bodyguards performing an action to be set by Ujiro. If the bodyguards do not follow through with the command, that clan is disqualified. So, Ujiro gives Shunsen the command, [[WhatTheHellHero "Kill me"]]. [[CrowningMomentOfAwesome He did, then committed suicide]]. The gathered Clan champions and bodyguards, shocked, conceded defeat. And then the Crane go and adapt the event for [[TheMovie Winter,]] because that's just how the Crane are!
* In the ''TabletopGame/{{Planescape}}'' setting, the modrons (little, clockwork creatures native to Mechanus) are like this. As the living embodiments of Law, they obey the orders of their immediate superior without question, as that is part of their nature, and they cannot comprehend disobedience. Unfortunately, with some of the weaker, less intelligent ones, they can't use their own judgment to interpret orders, and have to be told to do ''everything''. For example, if a group of monodrones (the lowest type) are told to "attack", they do so until they are slain or the superior tells them to stop attacking, even if that means fighting each other when all enemies are defeated. (Their description in the manual says that it is fortunate they don't have to eat, or they'd have to be ordered to do ''that''.)
* In the ''TabletopGame/YuGiOh'' game, the appropriately-named [[http://yugioh.wikia.com/wiki/Blindly_Loyal_Goblin Blindly Loyal Goblin]], so named because he cannot be controlled by the opposing player. (InUniverse, he appears to work for Dark Ruler Ha Des, as seen on the Trap Card, [[http://yugioh.wikia.com/wiki/Order_to_Smash Order to Smash]].)
* In ''TableteopGame/{{Warhammer40000}}'', many of the Space Marines felt this towards their Primarchs. Tragically, this meant that when the Traitor Primarchs turned to Chaos, they dragged their Legions down with them.

* In ''Franchise/{{Transformers}}'', Megatron usually has at least one Decepticon like this. Soundwave gets a gold star for consistency; '''GLORIOUS''' [[WesternAnimation/TransformersAnimated Lugnut]] for effort.

[[folder:Video Games]]
* The Heroine to the Hero in ''VideoGame/ShinMegamiTenseiI''. She ditches her role as the Messiah to follow whatever he believes in. She's a bro.
** Normally, in ''Shin Megami Tensei'' games involving demon summoning, [[WeCannotGoOnWithoutYou your death means a Game Over]], handwaved by your demons abandoning their now-dead master. However, in ''VideoGame/ShinMegamiTenseiIV'', should you fall in battle, any of your demons that are still alive will continue to fight until victory is achieved or they perish alongside you.
--->''The rest of the team is trying their best...''
** In ''VideoGame/Persona3'', Koromaru is a FictionalCounterpart of UsefulNotes/{{Hachiko}}. Even a year after his owner was killed, Koromaru would still go on the same walk that his owner used to take him on every day. [[spoiler:Koromaru is eventually revealed have a human-like intelligence and joins the party as a TeamPet to avenge his master, who turns out to be killed by Shadows.]]
* In ''VideoGame/DevilSurvivor'', Atsuro Kihara is the only character who will never abandon you no matter what path you take.
* Missile, from ''VideoGame/GhostTrick'', is ''literally'' this. After he dies [[spoiler:for the second time, this time with ghost tricks of his own, he opts to stay dead just to help save Lynne and Kamila]]. If that's not enough, the ending reveals that [[spoiler:Ray is actually Missile from a previous BadFuture where he couldn't save anyone with his swap trick, so he [[TheSlowPath goes back in time and]] [[UsefulNotes/{{Hachiko}} waits ten long years]] to make the black cat Sissel think he was the man in red, knowing that said main was tied to Lynne and Kamila's murders and Sissel is only concerned about discovering his identity]]. If that isn't the Crowning Moment of Undying Loyalty, what is?
* In ''VideoGame/ProfessorLaytonAndTheMiracleMask'', it's revealed at the end of the game that [[spoiler:everything that Henry had done for the last 18 years was part of his effort to find Randall and prepare for his possible return. He even entered into a false marriage with Randall's girlfriend, Angela, just to save her from being essentially married-off to another man]].
* T3-M4 in ''VideoGame/KnightsOfTheOldRepublicIITheSithLords'' (contrast the first game, where his only sense of personality is as a foil to HK-47) is noted by other characters as being loyal to The Exile and becomes quite the sociopath (but played for laughs as his victims are droids) when [[spoiler:she is captured by Goto]] and it needs to help rescue her.
** Also from the second ''[=KotOR=]'' [[spoiler:every single member of your party except Kreia due to the Jedi Exile's unique force bonds with them]], and even [[spoiler:Kreia likes the exile for being The Force's {{Ubermensch}}]].
** HK-47 is himself an example, as he is loyal to Revan almost to the degree of hero-worship.
* In the ''Franchise/MassEffect'' series, the defining characteristic of [[PlayerCharacter Commander Shepard]] (apart from being the Ultimate Badass Of The Known Space) is the ability to inspire UndyingLoyalty [[MagneticHero in his/her squad and crew members]]. This is {{Lampshaded}} a lot in ''VideoGame/MassEffect2'' by the Illusive Man, and most of the second game is, in fact, spent gaining the complete loyalty of his/her crew members (or at least making sure they won't be distracted by any personal business). [[WhatAnIdiot Or]] [[DownerEnding not]].
** The two returning squadmates from ''[=ME1=]'', Tali and Garrus, are already devoted to Shepard even before their loyalty missions in the second game. In particular, if you bring Garrus to the entrance of a quarantine zone for an epidemic that ''kills his species but not humans,'' he'll offer to follow you in even though you have human teammates available: "It's your call, Shepard. If you need me, I'm not going to let a damn cough keep me back."
*** Tali makes her hatred for Cerberus, the terrorist organization that Shepard is forced to work with in ''VideoGame/MassEffect2'', clear from the very beginning and tells Shepard that she's only joining the mission for his/her sake.
** Although she only joins the squad in {{DLC}}, you can learn that Liara's devotion to you drove her to absurd lengths between games. First, she went out of her way to find Shepard's body and prevent it from falling into the wrong hands. Then, she handed the body over to Cerberus despite her fears and mistrust of them because they were the only ones offering a small chance of Shepard coming back. Then, she embarked on a RoaringRampageOfRevenge against said "wrong hands", namely the Shadow Broker, the mightiest crime lord in the galaxy [[BerserkButton for daring to try to harm Shepard]]. And the reason she was so cold to you in the second game? She was scared senseless that Shepard CameBackWrong due to Cerberus' manipulation. But even with that fear, her loyalty to Shepard's cause never wavered, maybe even being the most loyal to Shepard's cause, which is saying a lot.
*** Can also fit into ViolentlyProtectiveGirlfriend to Shepard if s/he romanced Liara in ''VideoGame/MassEffect1''.
** In [[SuperSoldier Grunt's]] case, even before his loyalty's solidified he pretty much already has nothing but total respect for Shepard and is quick to defend him/her to those who dare spit on his/her name. All thanks to their very first exchange, when Shepard stood up to him (when Grunt had him/her pinned against a wall) and had a gun on him without him noticing it. Being a total badass will have that effect on [[ProudWarriorRaceGuy krogan]].
--->'''Grunt:''' Shepard is my battlemaster. S/he has no match.
** Then there's [[AcePilot Joker]] and Dr. Chakwas who are willing to follow Shepard into hell and back and even join Cerberus partly because they were bringing Shepard back.
** This loyalty also applies to Javik, the [[spoiler:last of the Protheans]]. This is probably because Shepard helps Javik's personal mission to defeat the Reapers.
** [[PapaWolf And of course Shepard him]]/[[MamaBear herself to his/her crew]]. [[BerserkButton Threatening the people under his/her command]] is ''not'' advised. EVER!
** Shepard can even inspire this in people (s)he's only worked with once or twice: in ''VideoGame/MassEffect3'', speaking to Kirrahe on the salarian homeworld will result in him promising to support you in retaking Earth, regardless of the salarian government's decision on the matter. [[spoiler:If the salarian government does decide not to support you, most likely because you cured the krogan genophage against their wishes, Kirrahe goes AWOL in order to join you... and takes the ''entire salarian Special Tasks Group with him!'']]
** Both subverted and played straight with Miranda Lawson. Subverted with the Illusive Man, as while she consistently proclaimed her undying loyalty to him and Cerberus, she eventually lost her idealistic vision of the organization and made a HeelFaceTurn. Despite some initial tension, it is eventually played straight towards Shepard.
** In ''VideoGame/MassEffect3'', [[spoiler:if the genophage is cured (and Wrex is still alive), then the entire krogan species get this towards humanity and Shepard in particular, with Wrex even promising that the krogan people would gladly lend areas of Tuchanka for displaced human refugees from Earth. This is a pretty significant gesture, since the krogan are about to undergo a massive population boom and desperately need all the land they can get]]. With the exception of humanity, they also provide more war assets than any other single race in the entire game.
** This point is finally [[SomeAnvilsNeedToBeDropped rather unsubtly driven home]] in the "Citadel" DLC for ''[=ME3=]'', where it is demonstrated that the main difference between Shepard and [[spoiler:his/her secret ShadowArchetype clone]] is that the former has ''friends'' who'd walk into a fire for him/her, while the latter only has ''minions''. Shepard's ability to inspire this kind of loyalty is so great that [[spoiler:his/her clone]] derisively refers to the Normandy crew as "The Cult of Shepard".
** The geth to the quarians, on a race-wide scale. Even though their quarian creators once warred with them and are still to this day utterly hostile to them, the geth value little more than the lives of their creators, and are horrified by the implications of having to destroy them, [[spoiler:which makes that very possible scenario in ''Mass Effect 3'' [[TearJerker all the more tragic]]]].
* In ''VideoGame/DragonAgeOrigins'', every party member's opinion of you will fluctuate depending on your actions. Be too evil and some will hate you, too noble, others likewise. It ''is'' possible to get them all to 100% approval, but their approval can drop without warning if you do the wrong thing in their eyes. The sole exception is your [[BigFriendlyDog Mabari war hound]], whose approval of you is eternally maxed out. Additionally, if the player character is of [[BlueBlood Human Noble]] [[MultipleChoicePast origin]], the Dog will have UndyingLoyalty from even before the game starts. Little Daddy's Boy/Girl got a purebred Mabari pup sometime in the past and by the time of the game, that pup has become [[HelloInsertNameHere Dog]].
** Also, Alistair. All of the other humanoid party members can be asked/directed to leave the party, but that's not an option with him, and even if his opinion of you drops down to nothing he will stay with you. For Alistair, the Grey Warden order was the only family he ever truly had, and you are the only other surviving member of the group in Ferelden. [[spoiler:He will only leave after the Landsmeet, and only if you decide to spare and recruit Loghain. It's actually a gameplay mechanic to ensure that there is at least one male Grey Warden at all times]].
* ''VideoGame/DragonAgeII'' promotes this trope to a gameplay mechanic: once you've maxed out a companion's Friendship or Rivalry, it will remain permanently locked there, signifying his or her unyielding loyalty to Hawke. In the endgame, this means that with a single exception ([[spoiler:Sebastian, whose loyalty to the [[TheChurch Chantry]] is greater than to Hawke]]), party members will stick with Hawke no matter what agenda s/he pursues.
** Varric, in particular, never abandons Hawke and is even willing to kill old friends of his to protect him/her. At the end of the ''Legacy'' DLC, if done late in Act 2 or Act 3, he tells of a conversation that Hawke has with his/her [[spoiler:dead mother]] and admits that it didn't actually happen. He took the liberty because he wanted his friend to get the closure he felt s/he deserved but never got. In ''VideoGame/DragonAgeInquisition'', it's revealed that, [[spoiler:despite telling everyone he had no idea where Hawke was, even when being threatened, he knew all along where s/he was and could get in touch with him/her at anytime. He never said this because he wanted desperately to protect his closest friend.]]
* As in ''Origins'', it's possible in ''VideoGame/DragonAgeInquisition'' to max out the Inquisitor's friendship with any/all of the nine companions. The ''Trespasser'' DLC, which takes place two years after the end of the main game, can show just how deeply the loyalty runs. Possible outcomes include [[spoiler:Dorian giving the Inquisitor a communication crystal that will let them talk to each other at any time, Iron Bull refusing to turn on the Inquisitor when ordered to do so by a high-ranking Qunari, and Varric presenting the Inquisitor with a noble title and estate in Kirkwall so they will always have a home]].
* ''VideoGame/DarkSouls'': Sif, the Great Grey Wolf. [[spoiler:Sif stands watch over his master's grave and will fight to the death in a [[FieldOfBlades field of the rusted blades]] of would-be grave robbers to protect it, even if he is [[PlayerPunch too weak to swing his sword without falling over]], and even if he recognizes you as the one who saved his life in the DLC]].
* In ''VideoGame/DemonsSouls'', there's [[AntiVillain the knight Garl Vinland and Maiden Astraea]]. [[spoiler: When Astraea accepted the Demon's Soul, all of her knights turned on and tried to kill her, save for Garl, who remained by her side. Garl refers to her as "Dearest Astraea", and will defend her to the death. Astraea herself is equally devoted to her knight, and will [[DrivenToSuicide commit suicide]] out of grief after [[YouBastard the player kills him.]]]]
* Generally, the noble antagonists in ''VideoGame/FireEmblem'' have like this as a key character trait which leads to their death. Also UndyingLoyalty to the main character is a common trait of most [[CrutchCharacter Jeigan characters]] including Jagen/Jeigan himself.
** [[spoiler:Wolf to Hardin]] in ''[[VideoGame/FireEmblemMysteryOfTheEmblem Mystery of the Emblem]]''.
** Ishtar to Julius in ''[[VideoGame/FireEmblemGenealogyOfTheHolyWar Genealogy of the Holy War]]''.
** Brenya and Murdock to Zephiel in ''[[VideoGame/FireEmblemTheBindingBlade Binding Blade]]''.
** Selena to Vigarde in ''[[VideoGame/FireEmblemTheSacredStones Sacred Stones]]''.
** Bryce to Ashnard in ''[[VideoGame/FireEmblemPathOfRadiance Path of Radiance]]''.
** ''VideoGame/FireEmblem'' has a musical theme in several of the games called "[[CrowningMusicOfAwesome A Knight's Oath]]." It plays when a character with a backstory in military service to the Hero's nation joins.
** In ''Path of Radiance'' and ''Radiant Dawn'' there is also Soren, the very blunt, cynical tactician who is distant and distrusts everyone...except his commander and best friend, Ike. His loyalty is ''so'' undying that if he actually ''[[FinalDeath dies]]'' in the final chapter of the second game (he is ordinarily spared for plot reasons) his final words tell Ike that he must outlive Armageddon, he tells multiple people including Ike himself that he will ''never'' leave Ike's side, and if Ike [[RelationshipValues chooses to leave him behind]]? He still thinks about Ike for the rest of his life. [[spoiler:Well, it's hard not to be loyal to the guy who was the first to treat you with any dignity at all ''and'' saved your life]].
** In ''[[VideoGameRemake New]] [[VideoGame/FireEmblemMysteryOfTheEmblem Mystery of the Emblem]]'', [[HelloInsertNameHere My Unit]] is ''intensely'' loyal to [[TheHero Marth]]. In return, Marth considers him/her a [[TheConfidant trusted ally and friend]].
** Ditto in ''[[VideoGame/FireEmblemAwakening Awakening]]'' between [[HelloInsertNameHere the Avatar]] and [[TheHero Chrom]]. [[spoiler: Notably, Chrom returns the favor in a late-game confrontation, telling another hero who is threatening the Avatar that even if the latter is an unwilling ManchurianAgent for the BigBad, he trusts him/her with his life]].
** In ''VideoGame/FireEmblemFates'', most playable characters will not join you if you turn against their country. Your retainers Felicia and Jakob, on the other hand, will follow you to the ends of the earth. In addition, Silas will join you on the ''Birthright'' and ''Revelation'' routes after you pummel him due to his intense personal loyalty to you.
** Mae and Boey are Celica's mage bodyguards in ''VideoGame/FireEmblemGaiden'' and are among the few people who know she's actually the last surviving heir to the Kingdom of Zofia. While they only had a couple lines of dialogue in the original game, the 3DS remake ''Shadows of Valentia'' expanded their characterization and made it pretty clear they are willing to die for her sake.
* Youmu Konpaku from ''VideoGame/{{Touhou}}'' is intensely loyal to her mistress, Yuyuko Saigyouji. In the fighting game, ''Immaterial and Missing Power'', Youmu briefly questions Yuyuko's actions but just as promptly castigates herself harshly for it.
** The same can also be said of Sakuya and her mistress Remilia. ''VideoGame/KoumajouDensetsu II'', one of the franchise's fangames, has her going on a RoaringRampageOfRescue for her mistress' sake.
* Possibly the TropeCodifier for Video Game examples would have to be The Boss from ''VideoGame/MetalGearSolid3SnakeEater''. "Loyalty To The End" is her BadassCreed and her primary motivation to the exclusion of all else. [[SerialEscalation The sheer scale of the sacrifices she makes in the name of that creed border on ridiculousness]]. [[spoiler: In short (no easy task), she killed her own lover and father of her child under orders, was irradiated during nuclear testing, shot in the head, horrifically injured while being a top secret participant in the Mercury Project, betrayed all of her friends to their deaths and ultimately murdered by her most beloved pupil after a lifetime of painful sacrifices without solace or reward, and condemned to be remembered as a traitorous war criminal. All in the name of the United States government, which she had known since childhood to be corrupt from within by a dying conspiracy, and purely so that conspiracy could steal a huge amount of money from Russia. And yet, "Loyalty To The End." The revelation in ''VideoGame/MetalGearSolidPeaceWalker'' that she was suffering from brain damage may undermine all this an iota however]].
** Her and the Sorrow's [[GenerationXerox counterparts,]] Solid Snake and Otacon. Even when the entire world is against them, [[HeterosexualLifePartners they will]] [[HoYay absolutely NEVER]] abandon each other. [[spoiler:Even at the very end of the series--the very end of Snake's life--[[CrowningMomentOfHeartwarming Otacon outright refuses to leave Snake's side]]. Snake's ''last word'' in the series is Otacon's name]].
*** Gray Fox is another great example in this series. Raised as a child soldier in Africa during the Mozambique Civil War during the 1960s where he was nicknamed Frank Jaegar by his enemies for his "frank" appearance as a boy which he tricked them with until he killed them as a fierce "hunter" (Jaegar is German for hunter). Big Boss defeated the young Frank when he attacked him on patrol one day and rescued him from the war and brought him back to a U.S friendly safe zone but unfortunately the Philosophers experiment on him and turn him into a mind-controlled super soldier and years later Big Boss rescues him from this fate as well. Frank joins Big Boss's FOXHOUND Unit and from the 1970s until the 1990s serves under Big Boss's command in conflicts all around the world and earns their highest title of Fox, but despite his prowess as a warrior Fox tells Snake of how once again Big Boss came to his rescue when he had been captured by the enemy and they tortured him. In Gray Fox's eyes Big Boss is a father figure and the man to whom he owes his life; this undying loyalty to the man is so extreme that he betrays America and joins Big Boss's Outer Heaven cause even going so far as to fight his friend Solid Snake in a battle to the death. Fox's loyalty wasn't to a country or an ideal but to a man, Big Boss.
** While he may be the TropeNamer for ChronicBackstabbingDisorder and a MagnificentBastard of the highest order, Revolver Ocelot will never betray [[spoiler:Big Boss]].
** Whether it's MSF or the Diamond Dogs, there will always be soldiers under Big Boss' command that will never betray him, the ones who won't leave you even if you're in the red. Never is this more evident to the player than in the [[spoiler:[[WhamEpisode quarantine mission]] in VideoGame/MetalGearSolidVThePhantomPain. Once you get past the soldiers that are either too afraid or too far gone from the infection, you'll find yourself in the lowest level you can get on the platform, where there are soldiers who aren't sure of what to do and will leave it to Big Boss to decide ([[ButThouMust even if they all must die as there's no way to cure them]]). They then salute and wait for you to kill them, humming the theme song of ''Peace Walker'' the whole time.]]
--->[[spoiler:"We live and die by your order, Boss."]]
*** Also, the wandering Mother Base soldiers who are wandering the wilderness and have gone feral, only to come to their senses and salute when Big Boss comes around to rescue them.
---->"I've been waiting for this day for so long!"
* Lyon from ''VideoGame/SuikodenV'' is very devoted to the Prince, on whom she also develops BodyguardCrush.
* ''VideoGame/TalesOfSymphonia'' demonstrates both the good and bad sides of this trope:
** Kratos's feelings of loyalty toward [[spoiler:Mithos]] have him lingering on the wrong side of morality for [[spoiler:thousands of years,]] including nearly all of the game.
** Botta's loyalty to his leader is his primary character trait, and even leads to [[spoiler:his HeroicSacrifice in order to save the party]] and thus make sure someone gets a message back to said leader.
** An odd example considering how he [[spoiler:[[HeelFaceRevolvingDoor spends a lot of the first game]]]], but Zelos can become like this towards Lloyd if you play a path that earns his trust. While the first game shows this a little, the second game drives it home as Zelos is the ''only'' character to have complete faith Lloyd's innocent (even ''Colette'' is shown to have a few doubts). He even ditches the party ''twice'': one time because he feels finding Lloyd is more important than their quest ''to save the world'', and the other time simply because Emil badmouthed his friend.
* Guy to Luke in ''VideoGame/TalesOfTheAbyss.'' Sure, he has a brief moment of weakness after [[spoiler: Luke destroys Akzeriuth,]] but he's the only one who returns to Luke's side voluntarily. After that, ''nothing'' will keep Guy from backing Luke up. When [[ColonelBadass Jade]] - in-universe, easily the most terrifying party member - suggests that Luke [[spoiler: pull a HeroicSacrifice,]] Guy lifts ''[[DidYouJustFlipOffCthulhu Jade the Necromancer]]'' off the ground by his collar. It gets to the point where he'll willingly hold Tear back, despite his pathological fear of touching women, at Luke's request, so Luke can [[spoiler: perform said HeroicSacrifice uninterrupted]]. Of course, as it happens, he's on the verge of tears.
** And don't forget [[TeamPet Mieu]]. He didn't give up Luke at any moment and recognized him as Master even [[spoiler:when everybody got sick of him over the Tartarus when they first got into the Qliphoth]].
** Luke himself had this towards Van, the only person to scold him and praise him and was his ParentalSubstitute. [[spoiler: Then it turned out he had [[YouHaveOutlivedYourUsefulness outlived his usefulness]] after Van used him to destroyed Akzeriuth and was just an UnwittingPawn that he didn't even see as human.]]
* Part of ''VideoGame/TalesOfXillia'''s plot revolves around [[DeconstructedTrope deconstructing]] this trope. Jude falls into a slump [[spoiler: after Milla dies]] as without the one he's loyal to he has no purpose. Muzet completely ''flips'' at being abandoned and is desperate enough to latch on to the FinalBoss to give her a purpose and someone to be loyal to. Wingul, meanwhile, loses himself in his loyalty to the point he most likely does things that his King would actually ''not'' approve of considering certain actions and lines.
* Deekin in ''VideoGame/NeverwinterNights'' is able to resist the BigBad, one of the rulers of the Nine Hells, and who is simultaneously offering him great power to crush the Dragons he served under and is using his TrueName to force him into helping. Merely telling Deekin you will miss him grants him will enough to fight off the most powerful magic in the planes.
-->'''M:''' Come, join me. What has done but hold you back from your potential? I could make you a force that all dragons would bow down to in fear! All the world would know your name, Deekin, and fear it!
-->'''D:''' No! You may be bigger than the boss, but...but...DEEKIN NOT LIKES YOU!!
-->'''M:''' You dare defy me, reptile?!
-->'''D:''' "That's right! Deekin defies you! Deekin stands by the boss...to the end!
* In ''VideoGame/FinalFantasyIX'', Steiner is portrayed as loyal to the royal family of Alexandria, there in which lies his [[ConflictingLoyalty personal conflict]] when he's forced to choose between loyalty to Queen Brahne and his sworn duty to protect Princess Garnet.
* In ''VideoGame/GodOfWar 3'', the spirits of the fallen Spartans will come to Kratos' aid when he invokes the "Army of Sparta" magic. Even in death his soldiers remain loyal to him.
* [[DragonInChief Sergei Vladimir]] to the Umbrella Corporation as a whole and Ozwell E. Spencer in particular in ''VideoGame/ResidentEvilTheUmbrellaChronicles'', for a stark contrast with his [[TheRival rival]], [[WildCard Albert]] [[ChronicBackstabbingDisorder Wesker]]. Unlike most of his coworkers, he is absolutely determined to go down with the ship that is Umbrella; this largely stems from Umbrella having given him a home and a purpose following the collapse of the USSR. By the end of the game he's the only person still trying to hold Umbrella together, and he goes so far as to deliberately transform into a monster to try and stop Wesker from taking over the remnants of the company. When he dies, the company falls apart, as Sergei was the only one who was really keeping it intact.
** [[VideoGame/ResidentEvilCodeVeronica Alfred Ashford]] displays similar tendencies with regards to his sister Alexia, to whom he is obsessively loyal, even going so far as to create a split personality version of her during her absence.
* [[VideoGame/TeamFortress2 The Heavy]] is intensely loyal to his teammates, [[HeterosexualLifePartners especially]] [[HoYay towards]] [[FanPreferredCouple the Medic]]. In the supplemental comics, the Soldier is this too, albeit more out of his ComedicSociopathy turning him into an EagleLand-flavored idiot whose brain seems to only classify others as 'good people to trust' or 'people to violently kill.'
** Ironically, [[AllThereInTheManual the comics]] reveal that the RED Medic doesn't reciprocate.
* Fenrich to Valvatorez in ''VideoGame/{{Disgaea 4|APromiseUnforgotten}}''. Hell, Fenrich's CatchPhrase is "All is for my Lord". Doubles as a subversion to FurAgainstFang, with Fenrich and Valvatorez, respectively.
* ''VideoGame/KidIcarus'': Palutena, goddess of wisdom, gets this from her angel (who is [[OneManArmy pretty much her entire army]]) Pit. He is very quick to get into a shouting match with all sorts of divinities that insult her, and [[spoiler:even when she was possessed and sent his lifeless body to slaughter untold amounts of innocent people, he gave everything to bring her back to herself again]].
* Captured Franchise/{{Pokemon}} will follow a trainer's every command, provided they like the Trainer enough.
** In ''VideoGame/PokemonBlack2AndWhite2'' there is the Shadow Triad, three mysterious, shadowy figures who are utterly loyal to Ghestis for some unknown reason. Even when Ghestis is defeated and is [[VillainousBreakdown driven mad]], making him no longer a threat, they will show up at a spot every month, challenging you out of desire for revenge. (They won't force you, however.)
** Before them, in ''[[VideoGame/PokemonGoldAndSilver HeartGold and SoulSilver]]'', Archer, top Team Rocket executive, displayed this to [[TheDon Giovanni]]. Despite being the current boss of a powerful crime syndicate, his entire plan revolved around getting Giovanni to come out of hiding and reclaim his place as leader of the organization.
** You have the option of releasing a Pokemon into the wild from the PC. If you try to do this to your very first Pokemon, it will come back and the game tells you "It was worried about you." Even if you've kept it in the PC ever since that was allowed.
** With the introduction of Pokemon Amie in ''VideoGame/PokemonXandY'', you can form close bonds with your Pokemon that can result in them overcoming status afflictions, dodging hits, hitting critically more often, and even REFUSING to faint all out of loyalty and love for their trainer.
** Gardevoir, in particular, deserves special mention. Throughout the games, one fact continually gets mentioned in the Pokedex: It will protect its trainer, even at the cost of its own life. Damn...
*** Similarly, Unfezant's Pokedex entry states that it will never allow itself to be close to anyone but its trainer.
* A defining trait of the character [[VideoGame/SoulSeries Voldo]] is his great devotion to his long deceased master, Vercci.
* Three characters in ''VideoGame/BlazBlue'' exhibit this trope, all of which have [[JustifiedTrope good reasons]] for doing so.
** [[GeniusBruiser Iron]] [[HollywoodCyborg Tager]] is a field officer and research assistant working under [[MadScientist Professor Kokonoe]], and would follow any order she gives him with minimal hesitation--he may question it at first, but that doesn't stop him from obeying. [[spoiler:He was an Ikarugan officer who was horribly injured during an operation to recover [[ArtifactOfDoom Deus Machina: Nirvana]] from the NOL, and Kokonoe [[WeCanRebuildHim literally had to reconstruct him]] into a demon-esque cyborg. She wiped some of his memories of a particularly traumatic incident soon thereafter, and had programmed him into total loyalty, but that is not to say programming and personality cannot overlap--even when he finds out about that incident, he is still loyal to her]].
** Valkenhayn [[BattleButler R. Hellsing]] is one of the Six Heroes who fought off the [[EldritchAbomination Black]] [[{{Orochi}} Beast]] over ninety years ago and is a massively hardened badass, [[spoiler:but well before it erupted from the cauldron in Japan he was a mere vigilante. One of his missions set him upon Claudius Alucard, who while trouncing him offered him a position as a butler to his house--Valkenhayn accepted and has been loyal to Claudius ever since. When Claudius set out to help Jubei and Hakumen banish Terumi to the Boundary, Valkenhayn swore to look after his daughter Rachel--ninety years in multiple timelines has passed and not once has he swayed from that vow, and he is one of the very few people Rachel genuinely respects]].
** [[GenkiGirl Makoto Nanaya]] had faced some of the worst FantasticRacism in the world and had grown a JerkassFacade just to get away from it all, but found herself opening up to Noel and Tsubaki when they stood up to the [[UpperClassTwit "noble" twats]] that took it upon themselves to bully her. The three became very close friends over the Academy years, and she came to accept Jin and Carl as well. To say that her friends are the framework of her new identity is not hyperbole - her "[[{{Determinator}} unyielding will]]" is all her own, but for their sake she is not afraid to make the rest of the world her enemy, going so far as to [[spoiler:defect from the NOL and send a thinly-veiled threat to Sector Seven through Tager]] just to protect Noel, and these bonds are literally ''half'' the reason (said "unyielding will" is the other half) [[spoiler:she manages to survive a round trip between timelines '''through the friggin' [[EldritchLocation Boundary]].''']]
* ''Franchise/JakAndDaxter'': Though [[DirtyCoward a coward]] who has a penchant for [[MilesGloriosus telling tall tales]] that primarily [[ItsAllAboutMe revolve around himself]], Daxter is defined by his undying loyalty to his HeterosexualLifePartner Jak. Even if he has no qualms [[SnarkyNonHumanSidekick voicing his dislike]] of all the situations Jak drags him into.
* Billy Kane of ''VideoGame/FatalFury'' and ''VideoGame/TheKingOfFighters'' is the right-hand man of Geese Howard. Before everything else, he is the right-hand man of Geese Howard. In the ''Maximum Impact'' sideseries, he abandons Southtown for England when Geese dies... but as soon as a new gang moves into Southtown, Billy goes back, because ''only Geese can rule Southtown''. When fighting Rock Howard, Geese's son, Billy's prefight dialogue is anger that Rock isn't taking up Geese's legacy.
* In ''VideoGame/{{Dishonored}}'', there's a villainous example in the form of [[ProfessionalKiller the Whalers]] to their leader, Daud. They are willing to risk their lives against a man more powerful and skilled than they are to defend Daud, and will only let Daud fight alone if he commands it; [[spoiler:after being badly wounded so that he can no longer fight, Daud has to tell them to leave a ''second'' time to get them to back off]]. A heroic example is [[PlayerCharacter Corvo]], who has UndyingLoyalty to the Empress and her daughter, Emily.
* VideoGame/FalloutNewVegas has the Ferocious Loyalty perk, which gives companions a serious boost to their damage resistance [[BerserkButton when the Courier is wounded badly]].
** Members of Caesar's Legion are all fiercely loyal to Caesar, at least to a point. In certain cases, there's at least one Legionnaire who is not above considering Caesar a megalomaniac who is clearly losing it (due to a severe brain tumor) and Ulysses was a former Legionnaire who has lost faith in the Legion, but still feels a certain kinship with it's men.
* Over the course of the ''Franchise/KingdomHearts'' series, Donald and Goofy become very loyal to Sora; a noteworthy example is when [[spoiler: they initially switch sides with Riku after his FaceHeelTurn because the Keyblade was intended for him all along and they have to serve whoever wields it. They immediately [[{{ScrewDestiny}} rejoin]] Sora and protect him when Riku tries to kill him, and as soon as this happens the Keyblade chooses Sora over Riku]].
** They also hold undying loyalty towards [[{{MickeyMouse}} King Mickey]], but [[spoiler: betray him at one point to help Sora fight alongside their allies in the [[{{TheWarSequence}} Battle of the 1000 Heartless]]. At least Mickey understands why they defied his order and forgives them]].
** And then, there's the [[{{Mon}} Dream Eaters]], particularly Meow Wow and Komory Bat, the respective starters of Sora and Riku.
* ''VideoGame/{{Boktai}} 3'' reveals some of the undead who actively oppose [[BigBad Ratatosk]] due to their loyalty to Queen Hel. [[spoiler:It turns out ''[[TheMole The Count]]'' is one of them and [[StealthMentor Stealth Mentors]] Django during their fight]].
* Stern and Levi towards their Lord Dearche in ''VideoGame/MagicalGirlLyricalNanohaAsPortable: The Gears of Destiny''. While they may infuriate her her several times and will flatly refuse Dearche's orders if they don't agree with it, everything they do, they do it for Lord Dearche's benefit. If they need to sacrifice their lives to ensure that their king survives and achieves [[SheIsTheKing her]] goal, they will do so without hesitation.
-->'''Stern:''' I am the flame that opens the path of my king...Even if I am extinguished, I will have no regrets.
* The Companions guild of ''VideoGame/TheElderScrollsVSkyrim'' exhibit this in spades for one another. They refer to each other as "Shield-Brother" and "Shield-Sister," and most if not all of them consider the guild to be their true family. This is driven home when the player character goes through their initiation rite, and a senior guild member essentially swears to die defending him/her if necessary.
** Housecarls and stewards exhibit this uniformly toward the Jarl or Thane to whom they have pledged their service.
* The Phone Guy from ''VideoGame/FiveNightsAtFreddys2'' loves the pizzeria (especially the animatronics) and just wants it to be a place where families can enjoy themselves. [[spoiler: When he finds out that someone killed a lot of children and realizes that the pizzeria is going to be closed down, he sounds very upset in his sixth message. This motivates him to take the night shift at some point just to figure out what's going on.]]
* The final installment of ''Monster Girl Quest'' introduces Eden, TheDragon to [[spoiler:[[BigBad Ilias]]. She is so unswervingly loyal to her master that it ''almost'' makes you [[CryForTheDevil Cry For The Angel]] when you learn Ilias doesn't care in the slightest about her and sees her as only a means to an end.]]
* In ''VideoGame/SuperPaperMario'', Blumiere and Timpani have this. Even though Blumiere [[spoiler:tried to destroy the multiverse]], Timpani still loved him.
** A one-sided example of this is Nastasia's love for Count Bleck.
*** All of Count Bleck's minions are like this[[spoiler:, except for the ones who are brainwashed or named Dimentio.]]
* ''VideoGame/KingdomsOfAmalurReckoning'': [[JadedWashout Agarth]] is this to [[PlayerCharacter The Fateless One]]. As he admits he used to be a hero before he [[spoiler: foresaw his own death]] and this flung him into a deep depression until he met you. He goes on to say that thanks to you he has a new lease on life and helps you more as a friend than because it's the right thing to do.
* N Gin is generally presented as such to Dr Neo Cortex in the ''Franchise/CrashBandicoot'' series, being both the SycophanticServant and TheIgor. He ditched Cortex only once, and even then indirectly to collect treasure. When given a true opportunity to betray Cortex to serve Nina, he fights with his conscience, but ultimately cares about Cortex too much and willingly gives Crash info to stop Nina and get him back in control.
** Tiny Tiger is a CharacterizationMarchesOn case. In the second game, he is Nitrus Brio's ally in stopping Cortex. Ironically in all games after he is Cortex's most loyal and consistent mutant. Especially evident in ''Crash Nitro Kart'' when Nash and [[spoiler:Real Velo]] [[GoThroughMe try to threaten Cortex.]]
** Pasadena Opossum in ''Crash Tag Team Racing'' is presented as such to Ebeneezer Von Clutch. She introduces herself in the racing contest as having competed solely to make sure Von Clutch keeps his park. Compare this to the rest of the park's workers, who openly despite Von Clutch and want to ditch the job the moment they can while [[spoiler: his other NumberTwo, Willie Wumpa Cheeks]], who is actually trying to off the guy and ruin the park by stealing it's gems.
* Throughout the multiple interpretations of ''Franchise/SonicTheHedgehog'', Tails being Sonic's devoted right hand man is usually one consistent.
* ''Franchise/TheLegendOfZelda'':
** This is showcased rather tragically in ''VideoGame/TheLegendOfZeldaMajorasMask''. The Ikana warriors encountered in the game guard the long abandoned and ruined Ikana Kingdom even in death, their ghoulish spirits still roaming the area out of a devotion to their commander. Link encounters the Captain of the Guards in this area and helps him find peace so he can pass onto the afterlife at long last; his last order as the Captain is for Link to let his soldiers know that the war is over. When told this, the soldiers in question finally let go of their obligation to the Kingdom and move on. The King of Ikana also still haunts his Kingdom, and even in death he protects his throne when he sees Link, thinking him to be an enemy. When Link defeats the King in battle, he laments to Link his sadness over the fall of his Kingdom and how foolish he was to let it happen, but he acknowledges that it is finally time to let go and rest in peace. As a parting gift, he gives Link the tools he needs to defeat the final dungeon of the game.
** About the only redeeming quality to the BigBad of ''VideoGame/TheLegendOfZeldaSkywardSword'', Demon Lord Ghirahim, is his unwavering loyalty to his master the Demon King Demise. All of his efforts in game are to free his master from his imprisonment.
*** This continues in ''VideoGame/HyruleWarriors'', where he follows Ganondorf due to sensing he is his master reincarnated.
** Since their introduction in ''VideoGame/TheLegendOfZeldaOcarinaOfTime'', the Sheikah tribe's loyalty to the Royal Family of Hyrule has been their [[PlanetOfHats cultural hat]] to the point of it making them a willing ServantRace. Impa's personal loyalty to Zelda in either's various incarnations is the most prominently portrayed, but there's also the devotion of the Sheikah Monks in ''VideoGame/TheLegendOfZeldaBreathOfTheWild'', with them spending 10,000 years in meditative stasis waiting for Link to complete their trials and give him Spirit Orbs and other items to help him defeat Calamity Ganon.
*** ''Breath of the Wild'' also subverts it by introducing the Yiga Clan, an offshoot of the Sheikah tribe. Unlike the rest of the Sheikah, the Yiga could not forgive Hyrule for turning on them. They still have UndyingLoyalty as their hat...but that loyalty is given to '''Ganon'''.
* In ''VideoGame/SaintsRow'', this is by far the most important quality of the Boss. He[[note]]or she, but called "he" here for simplicity's sake[[/note]] will ''never'' let a Saint down. If you're one of the crew, he will stand beside you no matter the circumstance. Get hurt? He'll pull you back to your feet. Get in trouble? No one will stop him from helping you. Someone kills you? God forgive whoever did it, '''''because he won't.'''''
* In older versions of ''VideoGame/{{Stellaris}}'', you could [[AndroidsArePeopleToo sign an AI Rights Accord]] and permanently etch the rights of synth pops as thinking, sentient beings into your empire's legal framework so they could never be enslaved or destroyed. This meant that if the [[RobotWar AI Uprising]] [[FinalBoss Crisis]] occurred in another empire, then your pops would refuse to join it and instead help their creators fight it.

[[folder:Visual Novels]]
* Several of the Servants in ''VisualNovel/FateStayNight'' would qualify. Saber, Berserker and Rider are probably the best examples, though the latter two are not immediately obvious. Archer has signs of this towards his master Rin from time to time [[spoiler:despite flat out betraying her in the route centered around him]].
** Especially notable in Saber's case, as she was betrayed by Kiritsugu in ''LightNovel/FateZero'' along with Irisviel, who she had true loyalty to. But even in arcs where Saber is bound and/or corrupted by magic, she still has an overriding protectiveness of Shirou.
** None in the franchise embodies it more than the Fourth Grail War's Rider, [[spoiler:Iskander, King of Conquerors]], whose men are so loyal to him that he [[spoiler:can create a Reality Marble from which to summon them to fight by his side once more. And later on, when Waver loses his Command Spells, Rider still sticks with him because, in his words, "Whether or not [you] are a Master, you are my friend, and that will never change."]]

* In ''Webcomic/{{Skins}}'', Jordan has stood by her werewolf lover despite the terrible thing he did during the Kettletown mission. She risks her own career to use an upcoming mission to give him a chance to redeem himself.
* In ''Webcomic/GirlGenius'' '''Everyone''' in Mechanicsburg, from [[SuperSoldier Jäger]][[BloodKnight monsters]] to the town butcher to every minion and constructed monstrosity in between, are loyal to the Heterodyne family, to the point of twenty years later they are still waiting for them to come back.
** [[LargeAndInCharge General Goomblast]] explicitly states that the Jägers are ''voluntarily'' loyal to the Heterodynes, having made a solemn decision to serve the house for the rest of their unending lives before drinking the SuperSerum that transformed them. The sole exception to this is Vole, who abandoned his oath and is no longer considered a Jäger by the rest.
*** It seems as though this, more than anything, is what gave the Heterodynes their power. Most [[MadScientist Sparks]] use various flavors of mind control on their creations, who eventually [[TurnedAgainstTheirMasters turn on them]]. Most--if not all--Heterodyne creations serve their masters voluntarily, even after centuries of service.
*** Heterodynes, apparently, gain the loyalty of both their own creations and those of others by [[http://www.girlgeniusonline.com/comic.php?date=20130710 NOT demanding it]].
** Natural minions will remain loyal to their Sparks, even against their better judgment. Mechanicsburg, ancestral home of the Heterodynes, happens to be completely populated with natural minions loyal to House Heterodyne, each one of them as much a latent-blooded brigand as their masters.
* ''Webcomic/SomethingPositive'': The entire oddball band of TrueCompanions has this as their primary virtue. Whatever else you can say about them, they're devoted to each other.
* ''Webcomic/{{Homestuck}}'': Becquerel, Jade's [[PhysicalGod First Guardian]] dog, is so completely devoted to her that [[spoiler:when he is prototyped, [[OmnicidalManiac Jack Noir]] (the resulting creation) inherits his loyalty to her and not only can't bring himself to kill Jade, but actually ''[[NiceJobFixingItVillain puts into motion the process of]] [[CameBackStrong reviving her after she is killed]]'']].
* In ''Webcomic/TheChallengesOfZona'', main character Mentl uses this trope to describe his feelings for Zona, swearing that he would die beside her, and ordering her never to tell her to save himself after [[spoiler:wiping out an army of monsters in a fireball that was hot enough to MELT the cave they were in to slag]].
* After the Kane arc in ''Webcomic/SonicTheComicOnline'', Tails is the only person who still believes in [[HeroWithBadPublicity Son]][[BrokenPedestal ic]].
* Durkon from ''Webcomic/TheOrderOfTheStick'' is so loyal to his TrueCompanions that he remains faithful to and helpful to them even after [[spoiler: being killed, turned into a vampire, and his alignment shifted from Good to Evil. Sadly, it turns out that this was all an act by the evil High Priest of Hel possessing Durkon. The real Durkon is trapped in his own body]].

[[folder:Web Original]]
* CrazyAwesome Jade Sinclair (Generator) to PersonOfMassDestruction Billie Wilson (Tennyo), in the Literature/WhateleyUniverse. To the point that she now has a demon mark on her [[spoiler:because part of Tennyo is not human]], and feels Billie's pain [[spoiler:through that mark]].
* While the real people of WebSite/ThatGuyWithTheGlasses show this off all the time (see real life), Ma-Ti in ''WebVideo/{{Kickassia}}'' lampshaded how WebVideo/TheNostalgiaCritic will do anything for the people he cares about.
* A villainous example in ''Literature/{{Worm}}'': Trickster, the leader of the Travelers, is incredibly devoted to his girlfriend, Noelle, [[spoiler:whom he [[NiceJobBreakingItHero dosed with a power formula]] that [[BodyHorror turned her into an anorexic's nightmare]]]], to the point that he's willing to [[spoiler:[[CavalryBetrayal betray]] ''everyone'', including his own team]], at her request, even when it means [[DidYouJustPunchOutCthulhu taking on the most powerful superhero on the planet]].
* [[http://cjcroen1393.tumblr.com/post/56257221009/fuckingradfems-barbellebeast This]] comic summarizes the loyalty of dogs. [[TearJerker Very accurately]].
* The Gaoians of ''Literature/TheJenkinsverse'' are so ferociously loyal to their Clan and friends, that when Ayma and Regaari learn that their friend (and Ayma's honorary Sister and clan member) Xiù Chang has made it home, they make an extraordinarily dangerous trip to [[DeathWorld Earth]] just to see her and make sure she's alright.
* ''WebAnimation/DSBTInsaniT'': Despite how little Dave seems to think of him, Evil Balloon still sticks around with him.

[[folder:Western Animation]]
* TJ from ''WesternAnimation/{{Recess}}''. He may seem like a [[ClassClown thoughtless goof]] at times, but the heights he'll go to for people he cares about--mainly [[TrueCompanions the Recess gang]]--are beyond belief.
** Examples include ripping his ''own'' pants so Mikey [[SelfSacrificeScheme won't endure humiliation alone]], deliberately calling a teacher "Mama" so the [[TakeMeInstead bullies pick on him instead of Spinelli]], pulling an all-nighter to get [[AFriendInNeed Gretchen the "A" she wanted]] and sending a ''telegraph message across the world'' to make sure Gus [[IGaveMyWord gets to the state fair]]. It even extends to authority figures and other random kids on the playground, as he refuses to befriend a cool new teacher out of [[MyMasterRightOrWrong loyalty to Miss Grotke]], [[SomeoneHasToDie endures the Dodge Ball Wall]] while putting the rightful king back on the throne and [[ZeroApprovalGambit pretends to be taken in by a public prank]] so playground order will be restored. He may be a pain in the arse for teachers, but as a friend, he will literally go to hell and back for you.
** Let's not forget the episode "Some Friend". In that episode, it's revealed that [[spoiler:TJ and Menlo were friends when they were four years old. As they got older, their interests changed, and they grew apart. At the time, TJ was such a huge part of Menlo's life that it was hard to let him go. So what does TJ do? Promise Menlo that, no matter what happened, TJ would come to Menlo's birthday party every year. He's still doing it.]]
* ''WesternAnimation/AdventureTime'': Marceline is shown to be incredibly loyal to Simon (AKA The Ice King) in the 5th season premier, where she, in an alternate reality where the Lich never existed, defended his body for 1000 years, making sure that nobody stole his crown.
* Chris in ''WesternAnimation/DanVs'' is this to the titular character. No matter how many times Dan has gotten him in a pickle, Chris still sticks by his side, even when he knows that [[AesopAmnesia Dan will never learn his lesson of his revenge schemes]].
* ''WesternAnimation/DarkwingDuck'': Launchpad is always loyal to Darkwing, in spite of the duck knight's HeroWithBadPublicity status, GlorySeeker nature, and snarking at his expense. Even on the (extremely rare) occasions when he's angry at him, he'll usually step up to help him again if Darkwing is actually in trouble.
* ''WesternAnimation/DuckDodgers''
** The show used a variant which featured a robot (a rare Warner Bros. acknowledgment of ''WesternAnimation/TheIronGiant'') serving as this to Dodgers, to the point of taking a meteor for Dodgers. In two different episodes.
** The Cadet is also no slouch in this department. He keeps [[{{Jerkass}} Dodgers]] out of trouble in spite of virtually never getting rewarded for it.
* In ''WesternAnimation/DuckTales1987'':
** By his own declaration, [[TheJeeves Duckworth]] "loves serving Mr. [=McDuck=]", and he'll continue under him even in cases like "Down and Out in Duckburg", "Super [=DuckTales=]", and ''WesternAnimation/DuckTalesTheMovieTreasureOfTheLostLamp'' where Scrooge loses his money and hence is not Duckworth's boss anymore.
** Although Mrs. Beakley originally came to the mansion because she needed work and a home for herself and Webby, she quickly becomes devoted to Scrooge, to the point of continuing with him even when he's lost his money and can't pay her as well as supporting him and helping him in ways (like saving him from drowning in shark-infested waters) that were not in the original contract.
** Launchpad's loyalty to Scrooge goes above and beyond the call of duty, to the point where he's helped him in some pretty big ways (like letting him and his family "crash" at his house) even when Scrooge has lost his fortune and thus he has no monetary reason for doing so.
** [[HeroWorshipper Doofus]] believes in [[IdiotHero Launchpad]] till the end, even when the whole world is picking on him. Launchpad returns the favor by being a PapaWolf towards his "little buddy", to the point where he's willing to fight hostile aliens and the Beagle Boys to protect him.
** Huey, Dewey and Louie might be rambunctious troublemakers at times, but they are infinitely loyal to Scrooge in his adventures. When Scrooge was framed for stealing a priceless painting (with very convincing evidence) neither the boys or any of the above in his employment believed it for a second and took measures to prove his innocence. This has been proven vice versa for Scrooge, as much as he treasures his fortune, it has been revealed his ''true'' worst nightmare is losing his nephews.
* From various ''Franchise/{{Transformers}}'' cartoons:
** Soundwave throughout the entire ''[[WesternANimation/TheTransformers Transformers Generation 1 Animated Series]]'', most notably in ''WesternAnimation/TheTransformersTheMovie.''
** Cyclonus of ''[[WesternANimation/TheTransformers The Transformers: Season 3]]'' towards Galvatron. In contrast to [[TheStarscream his predecessor]] as second-in-command.
** Glorious Lugnut from glorious ''WesternAnimation/TransformersAnimated'' Gloriously showed gloriously fanatical loyalty to glorious Megatron.
** Inferno and Scorponok from ''WesternAnimation/BeastWars''. Both acted as TheDragon, and both were the ''only'' Predacons to never turn on Megatron. Inferno is simply incapable of trechary or disobedience. Megatron loved having a minion with that kind of attitude. This particular version of Megatron [[WeHaveReserves views his troops as expendable]], but Inferno was the one pawn he ''wouldn't'' risk losing. As gleefully violent as Rampage ''and'' super loyal to boot? There's no wonder he's Megs' favorite.
** [[SilentAntagonist Sound]][[EvilGenius wave]] in ''WesternAnimation/TransformersPrime'' is undyingly loyal to Megatron, to the point where his presence is probably the only thing that stops Starscream from pulling the plug on the BigBad. This is pretty typical for Soundwave across multiple continuities, actually. VillainOfTheWeek Skyquake displayed similar loyalty (and in fact took it to LawfulStupid levels), refusing to work for Starscream because only Megatron could give him orders, and following the last set of orders Megatron gave him to the letter.
*** To really drive this home, Soundwave is more than willing to [[DefiantToTheEnd crash his own hard drive]] to prevent the Bots from hacking it.
*** Even when he returns in ''WesterAnimation/TransformersRobotsInDisguise'', breaking free from [[spoiler:the shadowzone]], his only interest is to contact Megatron.
** Skyquake's twin Dreadwing is also loyal to Megatron [[spoiler:but he reaches his breaking point after his sense of honor clashes with Megatron's ruthless pragmatism]].
** Predaking pledges undying loyalty to Megatron after revealing his sentience, but Megatron remains suspicious. He tries to reduce the potential threat Predaking poses [[spoiler:by wiping out the other Predacons]], which backfires [[spoiler:once Predaking finds out]].
** Ravage in ''WesternAnimation/BeastWars''. A former Decepticon rebuilt as a Predacon, he still remains loyal to the original Megatron long after the Great War. He is unimpressed by the current Megatron. [[spoiler:Seeing the message the original Megatron inscribed on the Golden Disk convinces Ravage to help the current Megatron. When Rattrap manages to blow up Ravage's ship, Ravage's last words are "Decepticons, forever!"]]
* Double D in ''WesternAnimation/EdEddNEddy'' has ''a lot'' of patience and tolerance for his friends' antics. In spite of Ed's unhygienic and otherwise gross nature and Eddy's scheming ways, Double D still sticks by them, [[ChronicBackstabbingDisorder even when Eddy would screw him over]]. With that being said, [[TheDogBitesBack it still doesn't stop him from getting back at Eddy whenever Eddy really goes far]], as shown in "Brother, Can You Spare an Ed?".
* Fry's dog Seymour in the ''WesternAnimation/{{Futurama}}'' episode "[[Recap/FuturamaS4E7JurassicBark Jurassic Bark]]". The night before Fry was frozen, he told Seymour to wait for him, and [[spoiler:he does just that. The dog spent the rest of its life laying outside the pizza joint, year after year, waiting for his master to return until he ultimately dies of old age, and ''you have to watch it during the end credits'']]. This was so [[TearJerker heartbreaking]] that the creators ultimately [[spoiler:retconned the entire thing with a complicated plot about time travel which involved a second Fry back in the past who stayed with the dog his entire life]].
* ''WesternAnimation/MyLittlePonyFriendshipIsMagic'':
** Rainbow Dash represents this as her Element of Harmony.
*** This is best demonstrated by the trial Nightmare Moon put her through in [[Recap/MyLittlePonyFriendshipIsMagicS1E2ElementsOfHarmony the second episode]].
*** Deconstructed by Discord in the second season premiere through a SadisticChoice and ConflictingLoyalty ([[spoiler:what's more important--your friends or your hometown?]]), with brainwashing thrown in for good measure.
*** In the season 3 episode where [[spoiler:Rainbow Dash goes to the Wonderbolts Academy]], after another recruit nearly kills her friends with a tornado and shows no remorse, she goes to [[spoiler:Spitfire, the Wonderbolts' leader]] and says that if they're going to promote recklessness in the pursuit of improvement, then she quits! Rainbow Dash, who's been [[spoiler:wanting to join the Wonderbolts since the pilot episode, is willing to give up her greatest and dearest wish]] if it promotes the behavior that put her friends in mortal peril.
** Spike feels this way towards Twilight, as the 2nd episode of season 3 shows that [[spoiler:his greatest fear is her not needing him anymore]]. Twilight's greatest fear, as shown in the same episode, [[spoiler:is the same but with Celestia]].
* Pets of the [[WesternAnimation/AvatarTheLastAirbender Avatar]] have been proven to be loyal until the very end.
** Momo displays this for Aang and Appa. When Aang is captured in Book 1's finale, he chose to stay in the oasis and wait for him. During his time in Ba Sing Se, he desperately searched the city in hopes of finding his big, furry friend.
*** On the opposite end of the spectrum is Appa during the time ''he'' was captured. He did everything in his power to get away from his captors to rejoin Aang and his friends. He even developed some loyalty to the Kyoshi Warriors after they cleaned him up and fed him.
** Roku's dragon, Fang, shows his loyalty by staying with his master while a volcanic eruption is taking place on his island. Even in his last moments, he curled around him (possibly trying to shield him from the eruption) and died with him.
** [[NonHumanSidekick Naga]] is this for team Avatar, especially to Korra in ''WesternAnimation/TheLegendOfKorra.'' She even goes outside of Republic City to find Korra when [[spoiler: Tarrlok captures her]].
* Kenny in ''WesternAnimation/SouthPark'' appears to be capable of this. In the movie he goes to hell so his friends can go back to the world as it was before the war. Also in a later episode he acted as a guardian angel for his sister Karen and protected her from bullies at school and their abusive agnostic foster parents.
* While Pinky is usually a regular oblivious BumblingSidekick in ''WesternAnimation/PinkyAndTheBrain'', his devotion to Brain is displayed in rather poignant levels at times. Despite the constant abuse and contempt Brain conveys over his stupidity, Pinky considers him his best friend and cheerfully goes through with every one of his orders. This is the guy who outright ''sold his soul to the devil'' in hope it could give Brain what he desired.
* In ''WesternAnimation/TeenageMutantNinjaTurtles2003'', the Guardians, were an organization of high-tech Ninja who were this towards the Utroms, acting as unflinchingly loyal agents bodyguards. [[spoiler:Splinter's deceased master Hamato Yoshi was one of them, and was regarded as one of the ''most'' loyal. As such, he was trusted with their greatest secrets, which is why he was targeted by the Shredder. It turned out to be pointless for the villain, as Yoshi was willing to die before he told them anything. (And sadly, he did.)]]
* PJ has this for Max on ''WesternAnimation/GoofTroop'', to the point where he will go out of his way to help Max even after Max spends the entire episode blatantly ignoring him or decides that they aren't friends anymore by falsely accusing him of being disloyal. [[TheSoCalledCoward Overall, he's apprehensive to a fault but he has saved Max's life multiple times without hesitation]]. When taken in conjunction with the fact that he has an [[AbusiveParents awful home life]] and a FriendlessBackground, and that [[LivingEmotionalCrutch Max provided a sanctuary for him to actually be happy sometimes]], this is close to inevitable.
* The DC Animated Universe:
** {{ComicBook/Darkseid}} is as villainous as you can get. Yet, when Superman defeats him with his own Omega Beams and throws him down to the slaves in [[Recap/SupermanTheAnimatedSeriesS3E12E13Legacy "Legacy"]], what do they do? Carefully carry him away, genuinely worried about his safety. When Superman seems confused as to why people he believe he had freed would help him, Darkseid himself musters enough strength to answer:
-->'''Darkseid:''' I am many things, Kal-El. But here, I am God.
** In ''WesternAnimation/JusticeLeague'' Darkseid ends up killed by the explosion of Brainiac's base, leaving Apokolyps in a civil war. When he's resurrected and comes back, everyone kneels and reaffirm their loyalty to him.
** A lighter DCAU example is ComicBook/JimmyOlsen. His loyalty to Superman never wavers, not even after Darkseid's {{brainwash}}ing him has made him a pariah to most of the planet. When asked for his opinion by a news crew, he vehemently retorts, "Superman's saved the world a million times. We ''owe'' him another chance!"
* Taken to disturbing degrees by Cyclops on ''Wolverine and the X-Men'' wherein he refuses to give up hope that his missing long time girlfriend Jean Grey may still be alive, despite his then current comic girlfriend Emma Frost being on hand.
* [[BattleButler Owen]] to David Xanatos in ''WesternAnimation/{{Gargoyles}}''. So much so that in "The Gathering" [[spoiler:Owen, aka ''Puck'' in a mortal guise, eventually overcomes his own perfectly justified fear of Oberon and fights his former liege to protect Xanatos and his family]].
* A turning point in ''Riders Of Berk'' is when the dragons move to protect their riders, without being commanded to do so.
* Ms Bellum is this to the Mayor in ''WesternAnimation/ThePowerpuffGirls''. In the BadFuture episode she's even shown becoming vicious and obsessed with his hat, years after he died.
* ''WesternAnimation/StevenUniverse''
** Pearl had this for Steven's late mother, Rose Quartz. She accepted exile from her home planet to be with Rose. She threw herself into extreme danger to protect Rose. Even after Rose's death, she's staying to defend Earth and Steven out of that loyalty. In "Sworn to the Sword", we find out just ''how'' loyal Pearl was to Rose; she was loyal to the point where she considered herself inferior to Rose, and [[StupidSacrifice constantly let herself get "poofed" to protect her]]. And if an argument with Steven is anything to go by, it got to the point where even Rose herself was concerned for her.
** Lapis also has this for Steven after he freed her and healed her gem. She warned Steven about two gems, namely Peridot and Jasper, that were coming to earth, and later fused with Jasper in order to keep her trapped in the ocean so she wouldn't hurt Steven, [[spoiler:though it's later confirmed that her [[InUniverseCatharsis motives]] for doing this [[SecretlySelfish weren't entirely selfless]], or at least she doesn't believe so.]]
** [[spoiler:Jasper]], of all [[VileVillainSaccharineShow characters]], is revealed at the end to have had this as a motivation in her hatred of [[spoiler:Rose Quartz]]. [[spoiler:Rose had allegedly shattered Pink Diamond, the original Diamond of both her and Jasper, in order to save the Earth.]] Thousands of years after her death, [[spoiler:Jasper]] remains completely devoted to avenging her - because it's the entire reason she ''exists''.
* Though a bundle of nasty vices most of the time, one of the few virtues the character Imp displays in ''WesternAnimation/SheRaPrincessOfPower'' is a fanatical loyalty to his boss, BigBad Hordak. This even applies to situations where it would be in the little guy's best interest not to be, something not always typical for bad guys.
* Waylon Smither's loyalty and devotion to Mr Burns comes off as downright romantic in episodes of ''WesternAnimation/TheSimpsons''. In one episode, situations left Burns bankrupt and thus Smithers no longer his employee. He took Burns to live in his home and continued doting over him and referring to him as "sir" as usual. He's not ''blindly'' loyal however, as episodes like "Sideshow Bob Roberts" and "Who Shot Mr. Burns" demonstrate.
* ''WesternAnimation/JackieChanAdventures'': After reforming, Tohru becomes devoted to the Chan family. In one such episode, Valmont uses an amnesia potion to make Tohru his servant again. It works until Jackie saves him after Valmont abandons him, and Tohru feels that "something inside" tells him Jackie is his friend.

[[folder:Real Life]]
* Dogs to mankind. [[http://www.theblaze.com/stories/heart-wrenching-image-dog-keeps-watch-over-fallen-seals-casket-during-funeral/ This dog]], for example, refused to leave the casket of his Navy Seal master.
** This dog Fido was the CanineCompanion to Jason Ellis, a police officer killed in the line of duty. [[TearJerker Fido put his paw on Jason's casket at the funeral, to show respect for his fallen friend]].
** There are multiple stories of dogs that have stood guard over the bodies of their masters, including [[http://www.telegraph.co.uk/news/newstopics/howaboutthat/2645720/Dog-who-stayed-by-dead-masters-side-for-11-weeks-honoured-with-statue.html a man who disappeared during the winter in the Welsh mountains]], [[http://www.denverpost.com/news/ci_25696727/dog-who-guarded-masters-body-colorado-wilderness-back here a man who went missing while skiing in Colorado]], [[https://en.wikipedia.org/wiki/Charles_Gough_(artist) and an artist who fell to his death in the Lake District]].
** [[https://www.youtube.com/watch?v=WEQ_-yJrL_Y Wiley crying at Gladys Eisenstadt's grave]].
** UsefulNotes/{{Hachiko}} would accompany his master to the train station every morning, then return later to await his return and accompany him home. Even after his master died at work, Hachiko would continue to come to the train station to wait for him. His undying loyalty made him an international legend, and helped to characterize loyalty as one of the traits of the Akita breed of dog.
** Britain's ultimate example of this is the legend of "Greyfriars Bobby", a Victorian terrier who allegedly guarded the grave of his owner in Greyfriars Kirkyard in Edinburgh for fourteen years, until he himself died. Not unnaturally, some attempts to debunk the story have been made, with the most recent one arguing that Bobby was simply a stray who made his home in the Kirkyard and was mistakenly assumed to be attached to a specific grave, and even that the original dog died and was secretly replaced by a second one to continue to attract free-spending sightseers.
** In general, it says a ''lot'' that Wiki/TheOtherWiki has a [[https://en.wikipedia.org/wiki/List_of_individual_dogs#Faithful_dogs list of dogs who were faithful to their masters.]]
* Marriage vows are often some form of a declaration of the trope:
-->"[Name], will you have this wo/man to be your husband/wife; to live together in the covenant of marriage? Will you love him/her, comfort him/her, honor and keep him/her, in sickness and in health; and, forsaking all others, be faithful to him/her as long as you both shall live?"
** They answer:
--->"I will."
* The RCA logo is an example of this. Painter Francis Barraud inherited from his brother a cylinder phonograph player, a cylinder of his brother talking, and his brother's dog. Francis noticed that whenever he played the cylinder, the dog would instinctively go to it and listen intently. He painted the scene, and RCA used it as their logo.
* Joseph Goebbels, in contrast to [[ScrewThisImOuttaHere Himmler]] and [[TheStarscream Goering]]. He remained at Hitler's side until the last minutes of the battle of Berlin and committed suicide two days after Hitler did.
** Ditto for his wife, Magda. And for that matter, Eva Braun, who committed suicide together with Hitler.
* One German officer told a story from UsefulNotes/WorldWarII when he was attached to a unit of [[UsefulNotes/FinnsWithFearsomeForests Finns]]. The Russians abducted a wounded Finn and subjected him to ColdBloodedTorture to lure his [[TrueCompanions comrades]] to come to his aid and walk into an ambush. The Finns instinctively grabbed their weapons and walked into the forest ''knowing perfectly well'' what the Russians were up to.
* At the beginning of the [[UsefulNotes/TheWinterWar Winter War]], a party of Finnish soldiers went to the house of an old [[DeterminedHomesteadersWife peasant woman]] and told her that the Russians were coming and they had to be [[KillItWithIce deprived of shelter]]. She went into her hut, solemnly cleaned and swept it and then lit the fire herself. She said, "This is my gift to Finland."
* During Stalingrad, a squad of Soviet troops were pinned down by German fire and tanks, with only [[EmergencyWeapon one belt of ammo]] for their turret left. One of them gets captured by the Germans. The captured Soviet then lies to the Germans and tells them his squad is completely out of ammo, and leads them to the one place where he knows his squad will be able to mow down the Germans with what little firepower they have. The captured Soviet soldier was later executed in front of his still-pinned down comrades, who were eventually killed when the Germans called in tanks to run them out.
* Similar to the above - during the siege of Malta a knight was captured in the opening skirmishes and was tortured for information on which part of the wall was the weakest and least defended. He instead directed them to the strongest section in the wall resulting in heavy Ottoman casualties. He was executed in front of his comrades in a very drawn out and painful manner.
* During the Sengoku Jidai, an ashigaru (non-samurai peasant foot soldier) named Torii Suneemon volunteered to go for help when the garrison at Nagashino, held by UsefulNotes/TokugawaIeyasu's forces, came under siege by Takeda Katsuyori. He successfully navigated his way through the Takeda defensive line and warned Ieyasu and UsefulNotes/OdaNobunaga about the siege, then volunteered to go back to report to the garrison ahead of the combined Oda-Tokugawa relief force. He was captured during his return, strung up on a cross in front of Nagashino castle, and was told to shout to the garrison that no help was coming and that they should surrender instead. Instead, when the Takeda expected him to demoralize the garrison with such tidings, Suneemon instead loudly proclaimed that relief was coming and for the garrison to hold the castle. He was promptly exected by the Takeda, but after winning the battle for Nagashino, Ieyasu was so moved by reports of Suneemon's bravery and unflinching loyalty, even in the face of painful execution, that he elevated Suneemon's family from peasants to the ranks of the samurai.
* [[https://en.wikipedia.org/wiki/Yi_Sun-sin Admiral Yi Sun-sin]], arguably one of the most gifted naval strategists the world has ever seen, was repeatedly betrayed and brought down by a corrupt, DeadlyDecadentCourt and [[WeAREStrugglingTogether political infighting]] in a time when they could ill afford it: the Japanese invasion of Korea under UsefulNotes/ToyotomiHideyoshi. He is renowned for setting very high standards for naval combat--namely, utter {{Curb Stomp Battle}}s, costing the Japanese dozens of ships while suffering no losses among his own fleet. None of his court-appointed predecessors or replacements accomplished anything remotely close, instead suffering devastating losses. In a time where other men would've simply thrown in the towel and abandoned any further efforts to work to save a government that was effectively shooting itself in both feet with every decision, Admiral Yi continued to fight to save Korea even when he was demoted or accused of treason repeatedly by jealous individuals. He likely did not do so out of loyalty to the court, but instead did so [[MyCountryRightOrWrong out of loyalty to his nation and its people]]. Yi was loyal even unto death, his sheer charisma motivating his fleet to win the day after he had been killed by a Japanese rifle shot in the middle of his final battle.
** He was even granted a title to honour this: ''The Martial Lord of Loyalty''.
* Some species of animal will remain faithful to their breeding partner for all its life. For example, the [[http://en.wikipedia.org/wiki/Tiliqua_rugosa Shingleback]] has been known to even stay by the side of their partner if they die for days on end.
** Pretty much all monogamous birds also qualify. Ravens have been known to sink into [[DespairEventHorizon depression]] when their mates die, sometimes to the point of [[DrivenToSuicide intentionally starving themselves to death]].
