A psycho supporter follows someone else's beliefs simply because the supporter is ''nuts''.

Used a lot to deconstruct other tropes, most notably the GenkiGirl, TheDragon, and SycophanticServant. If this character is initially a good guy, a FaceHeelTurn will most likely happen.

May also intersect with the PoisonousFriend, {{Yandere}}, LadyMacbeth, and OverzealousUnderling. A lot of Psycho Supporters also suffer from MadLove or the SubordinateExcuse if they're ''really'' devoted to the leader in question. Contrast StepfordSmiler.

Do not confuse with a character who supports a psycho; that's FriendToPsychos.

In real-life situations, they will usually be seen as a liability to the movement they support, and will constantly be told to StopBeingStereotypical.



[[folder:Anime and Manga]]
* In ''Manga/{{Bleach}}'', Tousen plays this to Gin's StepfordSmiler.
* In ''Anime/CodeGeass'', Diethard Reid, a TV producer who joins LaResistance not because he agrees with them, but because they're ''epic''. Rolo and V.V. -- murderous {{yandere}} -- count, too.
** Now now, lets be fair. Diethard was also bored at the time.
*** As Diethard explains in the second season, he hates the way the world has gotten and simply wants it to change, [[spoiler:meaning he'll latch onto whoever can change it. When Lelouch/Zero is chased out of the Black Knights, Diethard gloms onto Schneizel with the same fanatical devotion, which causes his death when he pulls a gun on Lelouch and is shot by a Geassed Schneizel.]]
%%* Misa and Teru from ''Manga/DeathNote''.
* Excel from ''Manga/ExcelSaga'' is a psycho supporter of Lord Il Palazzo. Il Palazzo may be using mind control to gain supporters, but Excel is the only one who acts unhinged around him. She also uses the SubordinateExcuse to hang around him.
* ''Manga/{{Eyeshield 21}}'': Hiromi Kisiragi of the Hakushuu Dinosaurs is a WeakButSkilled cornerback who is absolutely dedicated in his support of team leader Marco and centre Gaou. He is also very quietly insane, preaching a BloodKnight [[TheFightingNarcissist Fighting Narcissist]] philosophy that claims only strength is beautiful. This stems from his past as a weak, bullied chump, and plays directly into his support of [[TheJuggernaut Gaou]] and {{Ma|nipulativeBastard}}rco.
%%* Yuno from ''Manga/FutureDiary''.
%%** As well as Akise.
* ''Franchise/{{Gundam}}'':
** Yazan Gable of ''Anime/MobileSuitZetaGundam'', originally introduced as a PsychoForHire BloodKnight. He's eventually recruited by ManipulativeBastard Paptimus Scirocco, but unlike most of Scirocco's supporters, Yazan has no illusions about Scirocco's goals and seems to be following him purely for [[OnlyInItForTheMoney the long green]].
** Lady Une from ''Anime/MobileSuitGundamWing'' and her not-so-hidden adoration of MagnificentBastard Treize Khushrenada, whom she serves as his [[TheDragon Dragon]]. Her pacifistic "Saint" personality is the one that is most in love with him, but her "bun and glasses" personality is [[TheBaroness exceedingly cold and ruthless]].
*** Treize [[HandWave explains]] to his friend Zechs, and the audience by proxy, that Lady Une developed split personalities due to her feelings for him. She gets better, possessing a combination of "Saint"'s compassion with "Iron Une"'s competence.
* While there are plenty of zealots in ''Manga/{{Hellsing}}'' 'verse, the Iscariots are prepared to commit any sin in the service of the Lord.. because their ultimate goal is to continue the fight [[ToHellAndBack in Hell]].
* ''Manga/HunterXHunter'':
** [[spoiler:Shaiapouf]]. [[spoiler:His goal is to make the Chimera Ant King's plans a reality, and, when Komugi, the human girl the King has taken in and played Gung-gi against, threatens to have the King turn back on his original plans by having him [[MoeCouplet develop human emotion towards her]], Pouf has an epic breakdown and decides that it would be best to kill himself for the King's former ideals. Like Itsuki from YYH, his character seems to also have elements of MadLove and HappinessInSlavery added in.]]
*** It's especially funny because what he melts down about is that he almost just killed the girl to get her out of the way, before realizing that if she died his king could never beat her, never get over her, and never ''forget'' about her, and it would be the worst thing he could do. Therefore suicide pact with himself and screaming while he plays the violin.
** The other two Royal Guards are comparatively sane, though they have basically the same worldview. They're just...a lot more matter-of-fact and less romantic about it. Although when Pitou was on the ground in front of [[TheHero Gon]], begging to be allowed to save the life of the blind girl who was "of importance to one who is of importance to me" before Gon proceeded with the revenge killing attempt, that was pretty...[[WhatTheHellHero impressive]].
* ''Franchise/JoJosBizarreAdventure'':
** Half the supporters of DIO in Stardust Crusaders, special shout out to Vanilla Ice, who's so obsessed with DIO [[AxCrazy he'll outright KILL anyone who makes him destroy any images of the Vampire]]
** But then there's [[SinisterMinister Enrico Pucci]], probably the closest friend of DIO, and also the closest the vampire has ever been to [[HoYay a homosexual relationship]], the main antagonist of Stone Ocean, he has such an obsession with DIO, he's willing to [[spoiler:Achieve Heaven, a secret which was well-kept in DIO's diary, which of course he posseses, and RE-START THE ENTIRE UNIVERSE]], simply to see him again, he might be an insane priest, but he's one amazingly loyal friend.
* ''LightNovel/KyoKaraMaoh'':
** Oddly, some of Shibuya Yuri's most avid followers in are open to this accusation; i.e. following someone because of your own insanity rather than the merits of their position. Yuri's a Demon King, but his goals involve "world peace through people not fighting any more," "not doing his own paperwork" and "playing baseball."
** Gunter--apparently actually an extremely competent academic, highly skilled swordsman, and powerful majutsusha, despite coming off as a brain-damaged SquishyWizard. Being around Yuri just makes him dopey as hell, but also means he intently supports whatever Yuri wants, even when it's counter to every custom of the land.
** Conrad--almost as hypercompetent as he seems, and in fact a decent guy, but ''insane.'' Hard to say whether that first comes through when he tells Yuri that if Yuri gets killed Conrad will 'see him again soon' or when he is firm that to protect Yuri he will kill absolutely anyone, but that's just in the first dozen episodes, and by the end the level of his lifelong codependency issues have been thoroughly plumbed.
*** He doesn't really believe in this peace thing, but he believes in Yuri. Because it's Yuri. And Yuri is the center of his universe. Because someone has to be.
** Wolfram--well, okay, he's just an eighty-four-year-old teenager in love. Pass.
** Hube--his TheAtoner thing seems weirdly noble and is totally crazy, especially with the DeathSeeker element. Especially crazy when you find out that the sin he was banished for was being a gung-ho commander during the last war and being careless with the troops. Which people don't even hold against him because of all the soldiers who died, they hate him because ''the blind WhiteMagicianGirl everyone loved knowingly worked herself to death trying to heal his casualties''. So he's basically a scapegoat for the whole ruling class' guilt about everything that went wrong in that effed-up war. And then he follows Yuuri with dedication for not entirely buying into that, even though ''he'' still does.
* For a more literal interpretation of "Psycho Supporter": Amamiya Yuuhi of ''Manga/TheLuciferAndBiscuitHammer'' instantly pledges his complete loyalty to Princess Sami after she vows to stop the mages' plot to destroy the world so that she can do so ''herself'' with her own fists.
** Although after fighting the mage's golems, befriending his fellow beast knights, and coming to truly love both Sami and the world, he [[spoiler: decides to stop her by his own hands]].
* Baron Ashura and Count Brocken from ''Anime/MazingerZ'' loyally followed Dr. Hell. The remainder Hell's CoDragons do not count because Pygman and Gorgon followed their own agendas.
* Roberto from ''Manga/{{Monster}}'', in a thoroughly creepy fashion.
* ''Manga/OnePiece'':
** Bartolomeo was once a crime syndicate leader, but soon became a fan of Monkey D. Luffy, setting out to sea in hopes of finding him one day. He keeps up to date with all the news regarding Luffy, even knowing of information that the [[OneWorldOrder World Government]] does not want leaked. Bartolomeo finally catches up to Luffy in Dressrosa--while he is normally quite villainous, causing death and destruction wherever he goes, he will gladly support the more heroic Luffy in everything he does (and has thus far been of great help to Luffy). He also cuts the tongues off of or otherwise maims anyone who speaks ill of Luffy within earshot.
** Almost every subordinate member of the Donquixote Pirates falls here. Hell, [[spoiler: Trafalgar Law]] initially joined as a child due to suffering a psychotic break and seeing joining Doflamingo as his best chance to hurt as many people as he could before dying of a terminal illness. Doflamingo's only even become the figure he is today because the four executives of the crew, Pica, Trebol, Vergo, and Diamante, realized the power of his Haki and became his fanatically devoted followers on the spot, to the point of ''burning down a town'' because its uneven pavement caused kid-Doffy to trip. Other crew members are equally fanatical in their devotion, a mentality Doflamingo clearly encourages as it makes them easy pawns.
%%* [[spoiler: Sasame]] from ''Manga/{{Pretear}}''.
* [[spoiler:Kirika Kure]] from ''Manga/PuellaMagiOrikoMagica'' is willing to do absolutely everything for her best friend [[spoiler:Oriko]] (who she's in love with), [[spoiler:to the point where she kills other magical girls because Oriko tells her to.]]
* Ukuleleman from ''Anime/SpaceDandy'' is a huge fan of Space Dandy (the character), particularly in awe of his smile. Ukuleleman likes Dandy's smile so much that he invites Dandy to come visit his planet, where he intends to kill Dandy while he's smiling and preserve him as a statue so that Ukuleleman can admire Dandy's smile forever.
* Ralph Werec from ''Anime/StrainStrategicArmoredInfantry'' is one of these, and relies on the expectation of MadLove as a motive; he only pretended to be in love with Vivian Medlock and to have made his FaceHeelTurn for her sake. His motivations were far more scarring ([[GoodScarsEvilScars in more ways than one]]) and left him flat-out insane, and once [[YouHaveOutlivedYourUsefulness Captain Medlock outlives her usefulness]], he turns on her too.
* ''Manga/RurouniKenshin'''s Yumi Komagata and her love for the ([[ManOnFire literally]]) flaming Makoto Shishio.
** At least Yumi is secure in the knowledge that, [[MadLove in his own twisted way]], Shishio ''does'' love her back. [[spoiler: He ''does'' fatally injure her, but then he cradles her in his arms as she dies so [[LetThemDieHappy she can pass away in peace]].]]
*** CreepyCrossdresser Kamatari Honjou, on the other hand, is ''fully'' aware that he'll never be loved like Yumi (because he's not a real woman) or favored like Soujirou (because he's not as good a fighter), and yet he is ''still'' obsessively loyal to Shishio to the point that Misao has to knock him out and Chou has to ''lie'' to him in order to keep him from [[{{Seppuku}} killing himself in disgrace]] after he fails to carry out Shishio's last command to him.
** And then there's [[EvilGenius Hoji]], who is clearly insane. He follows Shishio out of a near fanboyish belief in the latter's ability to change the world, and [[spoiler: kills himself at the end when he realizes that he won't be able to spread Shishio's philosophy to the rest of the world]].
*** But he gets to go help Shishio and Yumi conquer Hell! Look how happy he is when Shishio asks if he's coming!
* Ni Jieni in ''Manga/{{Saiyuki}}''. Interesting in that he is both a Psycho Supporter of Gyokumen.
** Arguable since it's very possible that Ni Jieni is the one manipulating Gyokumen.
** At any rate, just using her. He's psycho, and he's backing her up, but his psychosis doesn't instill loyalty or associate him with her cause.
* Michiko of ''Anime/{{Texhnolyze}}'' is a seemingly quiet secretary/driver for Onishi. Then we see her collecting the Texhnolyze parts, many of which are still attached to living people...
* In ''Manga/{{Trigun}}'', Dominique the Cyclops seems to be following Legato like this, just as Legato follows Knives (which is far more obvious in the manga than the anime). Knives isn't exactly sane either, though.
** Dominique never gets much character development. Legato, though...even the comparatively sane anime version of him is, in fact, fucking nuts, and this is presumably most of the reason he's so dedicated to helping Knives KillAllHumans.
** Since Knives himself isn't human, his desire to kill them could be considered rational in light of his and his species experiences with them. But any human who knows the extent of his omnicidal plan and follows him anyway would be a psycho supporter. Legato hates all humans including himself and believes they deserve to die, an attitude which Knives considers enlightened for him.
%%* Dilandau in ''Anime/TheVisionOfEscaflowne''.
* Itsuki from the ''Manga/YuYuHakusho'' anime ''loves'' [[BigBad Sensui]] because... Sensui is beautiful. In all kinds of senses, with a stress on the functional beauty of tremendous power.
** In the manga, where Itsuki is more twisted, it's because he's gotten the opportunity to see all that [[IncorruptiblePurePureness purity]] get twisted and warped and spit out a shattered genocidal maniac who's more powerful than ever and still charismatic and brilliant. He compares it to [[CorruptTheCutie "a little girl who believes babies come from storks growing up to star in pornos"]]. He loves that kind of thing. He plays this ''so'' straight.

[[folder: Comic Books]]
* Some comics have played with the idea that Harley Quinn of ''Franchise/{{Batman}}'' was at least slightly cracked ''before'' she met SelfDemonstrating/TheJoker and that he simply unleashed her inner crazy, or that she'd still be just as nuts were he out of the picture...
* Glory to the chaos king in ''ComicBook/TheIncredibleHercules''

[[folder:Fan Works]]
* In ''Fanfic/ACrownOfStars'', former BigBad Winthrop was a psychopath, a rapist and a blood-thirsty dictator. His DragonWithAnAgenda -and current BigBad- Jinnai was a paranoid, megalomaniac, power-thirsty, rapist, raving lunatic. And after replacing his former boss he got ''worse''.
* Chiron in ''Fanfic/SOE2LoneHeirOfKrypton'' is Gendo's subordinate and he's even more depraved, more blood-thirsty and pettier than his boss. Gendo is a Manipulative Bastard and an asshole, but he's pragmatic: he doesn't go out of his way to mess someone up and he may deem torture as necessary but not enjoyable. Chiron? Chiron enjoys it.

[[folder: Films -- Animated ]]
* Implied with Le Fou in ''Disney/BeautyAndTheBeast''. Not only does he continue to follow Gaston and like him despite being treated like trash, but the literal translation of his name is "The Fool" or "The Madman".
* ''WesternAnimation/BatmanBeyondReturnOfTheJoker'': We see that Nanna Harley paid the Delia and Deirdre Dennis (better known as Dee Dee, Harley's granddaughters) bail to keep them out of jail. Even when Harley was calling them out, she '' paid their bail''. In an alternate timeline, those two managed to kill all the Justice League.

[[folder: Films -- Live-Action]]
* ''Film/TheDarkKnight'' incarnation of the Joker's various minions have a healthy proportion of madmen among their numbers, who follow him because of his own crazed will.
* The photojournalist played by Dennis Hopper in ''Film/ApocalypseNow''.
* ''Film/RepoTheGeneticOpera'' has the three Largo children for their father Rotti, and later, [[spoiler:Luigi and Pavi for Amber in her bid to get control of Gene Co.]] In both cases, the leader isn't really outright evil until you take into account that not only do they turn a blind eye to the activities of their supporters, they actively enable them. Pavi Largo is the creepiest example of this; he seems fairly well adjusted as far as scarred sex addicts go until the crazy comes out to play.
* ''Film/HappyGilmore'': Shooter [=McGavin=] is more than happy to use his borderline stalker as a weapon against Happy Gilmore, up to and including [[spoiler: running him down with a VW Beetle on a fairway]], so long as he can get away from him as fast as possible afterwards.
* In ''Film/FromDuskTillDawn'', Richie is unquestionably devoted to his more mature brother Seth. Of course, this could be simply because they're brothers. On the other hand, Richie seems to enjoy - really ''[[ForTheEvulz enjoy]]'' - being a criminal in ways that [[EvenEvilHasStandards even Seth finds repellent]]. When Richie rapes and murders a woman the brothers were holding hostage, for instance, it's hard to tell if Seth is upset because he's ashamed of Richie or because [[PragmaticVillainy Richie's psychosis has put a crimp in their carefully-laid plans]].
* In the horror movie ''Film/{{Nightwish}}'', a MadScientist who uses his graduate students as bait to investigate poltergeists at an OldDarkHouse, makes use of several patients from a mental asylum to control them because they're easy to order around.

* The Dennis Hopper character in ''Film/ApocalypseNow'' was modeled on "The Harlequin", a young Russian man in a harlequin-like suit in Joseph Conrad's ''Literature/HeartOfDarkness''. He views the AntiVillain of the novella, Kurtz, as some sort of religious cult figure (of course, Kurtz is plenty psychotic himself) -- and it is implied (cautiously, as the story was written in 1899) that [[HoYay he and Kurtz have been in a homosexual relationship]].
* Bellatrix Lestrange, in ''Literature/HarryPotter''. WordOfGod states that "her true love was always Voldemort," but he had no discernible affection for her, merely using her loyalty.
** Likewise Barty Crouch Jr. and a few others who are truly SycophanticServants and not in it for the power involved.
* The Vengeance in ''Literature/ATaleOfTwoCities''
* From the ''Literature/AlexRider'' series: Conrad, TheDragon of General Sarov. Sarov at least has a noble goal from his mindset. Conrad just wants to kill things.
* In the sequel to ''Literature/CharlieAndTheChocolateFactory'', ''Literature/CharlieAndTheGreatGlassElevator'', the President's [[GeneralRipper chief general]] is a PsychopathicManchild. ("[[StuffBlowingUp Let's blow everybody up!]] [[SayingSoundEffectsOutLoud Bam bam boom blam blam!]]") The President and the Vice-President have to constantly keep him from going rogue...and he does respectfully, if unhappily, defer to them, thus fitting this trope.
* In ''Literature/TheWheelOfTime'' there is Masema, a fanatic devoted to serving [[MessianicArchetype the Dragon Reborn]], whether he wants it or not. He raises a rabble and mostly terrorizes the countryside. The Dragon makes some perfunctory efforts to get him under control, but in the end he has to be put down.
* In ''Literature/TheLostStars'', one of [[TheHero general Drakon]]'s aides is colonel Roh Morgan, who, in addition to being an excellent assassin and bodyguard, is a bloodthirsty madwoman who has to be held back from murdering everyone she sees as a threat and who latched onto Drakon with enthusiasm of a {{yandere}} because she's convinced she's destined to [[spoiler:give birth to his child, whom she intends to raise to conquer all of human space]]. When Drakon realizes just how badly messed up she is, he's horrified.

[[folder: Live Action TV ]]
* ''Series/BuffyTheVampireSlayer'': Caleb of the First, whom he basically sees as God.
* Beautifully subverted on an episode of ''Series/{{Shark}}'', when [[spoiler: SerialKiller Wayne Callison's love-smitten publisher turned out to actually be [[TheMole a spy]] planted by Stark]].
* Connor on Season 4 of ''Series/{{Angel}}'', regarding his loyalty to Jasmine.
** With maybe an unhealthy dose of PapaWolf thrown in for good measure.
* A Season 5 episode of ''Series/{{Smallville}}'', called "Fanatic," features one of ComicBook/LexLuthor's political campaign supporters going berserk and trying to kill his opponent [[spoiler:Jonathan Kent]].
* ''Series/TrueBlood'': Roy, the little toad who cheers Marnie's wholesale destruction and mayhem. She has her tortured backstory as the reason he does this; he just seems to think it's fun.
* ''Series/TheOfficeUS'': [[PsychoForHire Dwight]] to {{M|anChild}}ichael.

[[folder: Professional Wrestling]]
* [[Wrestling/StevieRichards Steven Richards]] was like this to Wrestling/{{Raven}} and [[Wrestling/LisaMarieVaron Victoria]], even as the latter got BoredWithInsanity.
* The Basham Brothers to Shaniqua, who was the "center of their universe". She treated them well, all things considered, or at least as well as you could expect, [[{{Dominatrix}} given her profession]].
* Jon Heidenreich was like this to Wrestling/BookerT who "showed him the light" in the form of a steel folding chair to his skull. Jon then moved on to [[Wrestling/TheRoadWarriors Road Warrior Animal]].
* Wrestling/MickieJames, until she realized her obsession with Wrestling/TrishStratus was unhealthy and mellowed out.
* Wrestling/RosaMendes, who debuted on ''Raw'' assaulting Wrestling/{{Melina}} for "stealing" Wrestling/BethPhoenix's championship (as in winning in a wrestling match). Beth's boyfriend Wrestling/{{Santino|Marella}} had advice on [[TeamPet how they could make the relationship work for them]] but Beth just took her support for granted.
* [[Wrestling/NickDinsmore Eugene]] to Wrestling/TripleH. Unlike most examples, Eugene wasn't violent, overly obsessive or a danger to Triple H's reputation. No, he was just [[UnwittingPawn blind]] to the fact Triple H was no good for him, or anyone else.
* If it's a [[Wrestling/RingOfHonor Women Of Honor]] segment or [[GirlsNightOutEpisode show]] and you see BJ Whitmer appear, then chances are you're about to hear about Kelly Klein, ''[[CharacterFilibuster a lot]]'' about Kelly Klein. Up until their Fight Without Honor at ''Best In The World'' she was the one thing that could take his mind off of destroying Steve Corino. Klein for her part seems to appreciate it on some level, because she will attack those who try to shut Whitmer up.

* Mrs. Lovett, the female lead of ''Theatre/SweeneyToddTheDemonBarberOfFleetStreet''. Spurred on by obsessive (unrequited) love for the title character, she shelters him despite his tendency towards psychopathic murder and comes up with the plan of disposing of the corpses he produces by baking them into meat pies and selling them for, to her great satisfaction, a tidy profit.

[[folder: Video Games]]
* [[TheDragon Arl Rendon Howe]] from ''VideoGame/DragonAgeOrigins''. As opposed to his boss, Teryn Loghain, who is a very complex WellIntentionedExtremist and AntiVillain, or Ser Cauthrien, Loghain's other Dragon and a conflicted and honorable woman suffering from MyMasterRightOrWrong, Arl Howe is a nasty piece of work, who is only in it for power and who participates in the dirtiest dirty work that Loghain [[IDidWhatIHadToDo unfortunately feels needs to be done for the sake of his homeland.]] This actually hurts Loghain quite a bit, as other people in power are disgusted by Howe's actions, as well as his plain {{Jerkass}} behavior.
* Kefka in the first half of ''VideoGame/FinalFantasyVI''. Unfortunately for his boss, Emporer Gestahl, he [[TheStarscream proves]] to be a little bit ''too'' [[OmnicidalManiac psycho]].
%%* Xenobia from ''VideoGame/LunarTheSilverStar''.
* [[DesignerBaby Grunt]] from ''VideoGame/MassEffect2'' is a [[DownplayedTrope subdued]] example of this. He doesn't much care about defeating the Collectors or saving the galaxy, and follows Shepard mainly because Shepard has many powerful enemies, which amongst [[ProudWarriorRaceGuy his culture]] is [[EnemiesEqualsGreatness a sign of greatness]]. Plus it gives him an excuse to [[BloodKnight kick lots of ass.]] He basically sums this up on Tali's recruitment mission, upon seeing the [[SpiderTank Geth Colossus]]:
-->'''Grunt''': ''This is why I follow you Shepard, big things!''
* In ''VideoGame/MetalGearSolid'' Psycho Mantis supported Liquid Snake's armed revolution... only because it meant he's allowed to [[AxeCrazy kill more people]]
* ''VideoGame/MegaManXCommandMission'' has Dr. Psyche, a member of the Rebellion forces and the boss of Chapter 4. Epsilon may not be mad--he swings closer to WellIntentionedExtremist than some kind of OmnicidalManiac--but Psyche is wholly dedicated to the Rebellion and way too pleased to basically be a MadScientist stereotype, stunning lack fo ethics, empathy, and all.
* Subverted in ''VideoGame/MegaManX4'': [[TheDragon Colonel]] was motivated by pride when he followed General who led Repliforce on a non-violent secession from humanity after being labeled Mavericks due to a tragedy where Repliforce weapons were used. [[spoiler: Sigma manipulated Magma Dragoon into making the attack so Dragoon could fight with X and Zero]]. The fact that Repliforce was "the most powerful army in history" and ''wasn't'' leaving their weapons behind for the secession didn't gel too well with the powers that be.
** Actually, Colonel may fall under TooDumbToLive. See, the entire conflict started when Colonel refuses to surrender and come in for questioning so an investigation as to why Repliforce robots were seen at Sky Lagoon (which had been crashed into a city by Mavericks, leading to untold amounts of devastation). The reason this is TooDumbToLive is because X/Zero flat-out state to him (not an exaggeration; I cannot stress enough that it is said to his face) that if he does not come in, the officials will have no choice but to assume Repliforce crashed Sky Lagoon and declare them Mavericks. And Colonel states that [[HonorBeforeReason his pride is more important]], leading to his death, his sister's death, his army's death, and his leader's death. Great going, Colonel.
* Used straight in ''VideoGame/MegaManX5'': Our introduction to Dynamo has him begging Sigma to be allowed to let an orbiting colony crash to Earth, so he can draw out the top Maverick Hunters for a fight. As far as we know, that is his only excuse for teaming up with Sigma (he doesn't even show up in Sigma's fortress at the end, like the ally/patsy typically does).
* Strega member Jin, from ''VideoGame/{{Persona 3}}''.
** Hell, [[spoiler: Takaya supporting Nyx in the end of the world]] is right there too.
* [[ColonelBadass Colonel]] [[FormerRegimePersonnel Sergei]] [[DirtyCommies Vladimir]] is this in ''VideoGame/ResidentEvilTheUmbrellaChronicles'' with regards to [[TheManBehindTheMan Ozwell E. Spencer]]. Spencer and his MegaCorp, Umbrella, gave Sergei a home after the collapse of the USSR, and the mentally unstable Russian is obsessed with repaying Spencer for this. He tries to hold Umbrella together long after everyone else has jumped ship, goes out of his way to cover up the corporation's mistakes, and finally [[OneWingedAngel transforms himself]] into a monster in a [[UndyingLoyalty last-ditch effort]] to prevent [[ChronicBackstabbingDisorder Albert Wesker]] from taking over the company's remnants. As Sergei himself puts it, "All for Umbrella!" It's a motto that Sergei takes very, very seriously.
* A subplot in ''VideoGame/{{Sam And Max|FreelancePolice}} Season One'' is [[AxCrazy Max]] being a fan of Hugh Bliss, the founder of the [[ChurchOfHappyology Happyology-esque]] religion Prismatology.
** While he took his own share when [[spoiler:he and the Molemen (and Norrigton) were the only sane in a world of Psycho Supporters of Sammun Mak, in the third part of ''They Stole Max's Brain'']]. This can also double as BrainwashedAndCrazy.
* Nouhime in ''VideoGame/SengokuBasara'' is an example of this. She is unquestionably loyal to her husband UsefulNotes/OdaNobunaga, but the said husband pretty much didn't care, just enjoying being the BigBad.
** In the third game, Ishida Mitsunari was this for Hideyoshi, despite not showing up in the second game. Upon his lord's defeat he goes on an AxCrazy RoaringRampageOfRevenge against Tokugawa Ieyasu. Mitsunari all but worships the man as a god.
%%* ''VideoGame/SkiesOfArcadia'': Ramirez.
* Albel the Wicked for roughly the first third of ''VideoGame/StarOceanTillTheEndOfTime''.
* [[spoiler: Nagito Komaeda]] from ''VisualNovel/SuperDanganRonpa2'' idolizes the Super High School Level students that are trapped on the island, and is willing to do anything to help them excel, even if it means sacrificing himself in the process. [[spoiler: Unfortunately, this also means setting up the first murder of the game, and then roping Hanamura into it without him realizing. With team leader Togami dead, he hoped to drive the rest to despair, only for them to regain their hope and overcome it in the end.]]
%%* Caina from ''VideoGame/WildARMs2''.
* In ''VideoGame/{{Xenogears}}'', Ramses to Emperor Cain. He loses his marbles by the end and pulls a Kefka.
* Pellegri to Margulis in ''VideoGame/{{Xenosaga}}'', though she occasionally proves more conscienable than he is. Still, the crazy is strong in this one, which becomes particularly apparent on Michtam.

[[folder: Western Animation]]
* ''WesternAnimation/AvatarTheLastAirbender'': Princess Azula's devotion to Fire Lord Ozai. Though it's kind of unclear with her whether she follows the world-conquest thing so intently because she's insane, or because she was raised to conquer the world, or because of bad genetics Zuko managed to avoid, or...anyway, she follows Ozai as much because [[DaddysLittleVillain he's her father]] and she wants to please him as because she's a megalomaniac. A little more megalomania and she could have offed him at a some point.
* Harley Quinn from ''WesternAnimation/BatmanTheAnimatedSeries'' is an interesting take in the trope, because without someone to lead her, Harley doesn’t have the motivation to commit crimes. Unfortunately, [[MadLove her love for]] SelfDemonstrating/TheJoker [[MadLove keeps dragging her back to his side]].
** The Joker abuses her with glee, until his death. After that, is implied she chose a tranquil life.
** Poison Ivy also abuses Harley and doesn’t want to give her enough credit for her part at their heists.
* Inferno, the pyromaniac fire ant from ''WesternAnimation/BeastWars'', is kind of an interesting case. Due to his beast mode instincts being so overpowering he firmly believes that he is an ant and that Megatron is Queen of the colony. This means Inferno is literally incapable of disobeying orders from his Queen, a trait that makes him one of Megatron's most valuable troops.
* ''WesternAnimation/CountDuckula'': Igor is a CardCarryingVillain who was loyal to all of Duckula's predecessors and thus to the current one, though not without expressing his displeasure and disappointment with his master's friendliness and harmlessness. That is why he tries, without betraying him, to turn him more to his liking like the forebearers.
