* [[FanFic/{{Alex}} Alex]] wants to make Marceline [[LaserGuidedKarma pay for everything she has done]] by getting her position as the new Vampire Queen. How does she do that? Turn the Land of Ooo into a dark swamp and blame her for it.

* The Northern Water Tribe in ''Fanfic/ReluctantHero'' tries to restore balance in the world and searches for the Avatar in order to fulfil this goal. When they find the teen, they abduct him - [[TheKindnapper while thinking they're rescuing him from the Fire Nation]] - basically imprison and force him to follow their customs, and consider wiping his memory clean from everything related to the Fire Nation in order to help him progress. Is that such a wonder that the kid escaped?
* ''FanFic/AnotherBrother'' has Prince Iroh, who's determined to bring his nephew home. Unfortunately, the nephew is very keen on avoiding this and constantly flees away. Iroh's reaction to that is burning anyone and everything trying to help the boy.

[[AC: ''Series/BabylonFive'']]
* In ''FanFic/TheDilgarWar'' Supreme Warmaster Gar'shan, the saner members of the Warmaster Council (like the protagonist Jha'dur, also known as [[NamesToRunAwayFromReallyFast Deathwalker]]), and the Dilgar emperor are trying to save the Dilgar race from the imminent explosion of their homeworld's sun. To do so they invaded the League of Non-Aligned Worlds, with the intent of conquering a paradise planet with adequate infrastructure already present for their people and the rest of the League for their advanced technology and worlds in which their population would be able to move when they'd grow too much for a single world, and intend to kill or enslave ''and'' work to death every single inhabitant of the League to make space and have the workforce they'll need for the first period. To be fair, they know exactly what they are, and their plan also includes making sure the next generation of Dilgar will be better people than themselves.

* In the ''Manga/{{Bleach}}'' fanfic ''FanFic/AProtectorsPride'', Ichigo says this about Aizen. Ichigo claims that Aizen might have wanted to change Soul Society for the better, but he unfortunately picked up a GodComplex. Along with his inability to talk to others as equals, this led to the monster he became.

* In ''Fanfic/ChildOfTheStorm'' and its sequels, it's revealed that Doctor Strange is this. Thanks to his unsurpassed skills as a master of [[TimeMaster Time Magic]] and as a {{Seer}}, he saw that in the vast majority of futures, humanity fell to Thanos, along with the rest of the universe. As a result, he set about weaponising the ForWantOfANail trope (he even quotes the original poem in chapter 80 when explaining himself, then asking how the Avengers thought he would have helped more, as just one more knight on the battlefield, or as a travelling blacksmith, there to replace the horseshoe) via extensive time travel and [[ManipulativeBastard epic scale personal manipulation]], to guide Earth to the best possible future, one where it can take on Thanos and win, shaping Harry into the tip of the spear. The measures he takes to ensure this happens, and the things he allows to happen lead to him sadly [[FallenHero reflecting that]] [[HeWhoFightsMonsters in many ways he is as much a monster as the creatures he fights]] in the sequel, ''Ghosts of the Past.'' His main redeeming features, such as they are, are that [[PetTheDog he does little kindnesses where he can]], he will not put anyone through something that he won't put himself through, his methods of shaping Harry into a soldier involve giving him a strong support system in the form of a loving FamilyOfChoice, and when he [[MyGreatestFailure fails]] [[spoiler: Rachel/Maddie]], he almost kills himself frantically rearranging the timeline to make amends and give her a happy ending.
* The ''Franchise/ShinMegamiTensei'' and ''Sono Hanabira Ni Kuchizuke Wo'' crossover ''Fanfic/MegamiNoHanabira'' has Shusui Naito, the leader of the Yakuza Demon Tamers. During his battle with the girls he reveals his ultimate goal: to spread the Demon Summoning Program outside the city, to as many people as he can. When Yuuna protests that it would likely cause a societal meltdown as people abuse the Summoning Program, Naito counters that that is what he's counting on: when social order breaks down, people who have been historically oppressed will have a chance to use the Summoning Program to take revenge on their oppressors and claw their way to the top without being held back by arbitrary societal constraints. Ultimately, he dreams of an {{Ubermensch}} that will prove themselves worthy of ruling the world through skill with the Summoning Program and the charisma to rally people beneath them, leading the world to a [[UtopiaJustifiesTheMeans golden age.]] The death, destruction and mayhem that would likely ensue in the meantime means very little to him.
* The ''WesternAnimation/JackieChanAdventures'' and ''WesternAnimation/{{WITCH}}'' crossover fanfic ''Fanfic/{{Kage}}'' (part of ''FanFic/ProjectDarkJade''), has one of these, in the backstory -- long ago, a disciple of Kandrakar, Althair the Mad Sage, led a crusade across the Known Worlds, killing thousands (especially children) in order to prevent Oracle N'ghala's vision of the "Incoming Darkness" from coming to pass.
** Nerissa ''believes'' she is one, but thinks that the best way to a peaceful universe is through obedience to her and her alone.
* ''FanFic/DeathNoteEquestria'' offers up several examples:
** [[VillainProtagonist Twilight Sparkle]], as Kira, has set upon a quest to eliminate all crime in Equestria, by killing all criminals. And she's willing to kill innocents as well, in order to protect herself.
** [[spoiler: Fluttershy]], the Second Kira, likewise believes in Kira's message, and is willing to kill anypony who speaks against her. [[{{Hypocrite}} Twilight objects to this.]]
** [[HeroAntagonist L]] is willing to go to any lengths to stop Kira, no matter how morally objectionable.
** Ace, leader of the Kira Neutrality Movement, believes that the only way to stop Kira is to remove her motivation (crime), and is thus pushing for harsher laws. That this would border on turning Equestria into a PoliceState and in no way prevents Kira from being a KarmaHoudini are acceptable consequences to him.
* An interesting case in FanFic/DungeonKeeperAmi. Both [[spoiler: Empress]] Mercury and The Light qualify in different ways. Mercury wishes to return home, despite bonding to a Dungeon Heart, wich means if she succeads she will draw the Dark Gods after her. The Light knows that Mercury is an unwilling Keeper and has no intention of harming her native world, or the world she now lives in. However, they see no alternative but to oppose her as there seems to be no way to help her without also helping the Dark Gods.
* ''Fanfic/FalloutEquestria''
** Red Eye is this, and naturally fits FaceHeelTurn too. He started his own personal quest to rebuild Equestria, probably long before Littlepip even found her Cutie Mark, but became so driven to reach this huge goal that he let go of his morals. Soon, he had built up an empire upon the backs of slaves, hired merciless mercenaries to protect his assets, and forged a deal with The Goddess (which he planned to break once he worked out how to become a God himself, and kill The Goddess), who was a genocidal maniac herself. All of the things he did, no matter how horrible, were done to achieve the noble goal of rebuilding Equestria and bettering the lives of its inhabitants.
** Littlepip can classify as one too, or at least she have shades of it. [[spoiler:Scootaloo]], on the other hand, is a more straight example.
* In ''[[FanFic/JusticeLeagueOfEquestria Mare of Steel]]'', this is how [[GeneralRipper Steel Wing]] sees himself, willing to do whatever it takes to [[BewareTheSuperman defend Equestria from Supermare]]. However, it's clear both in and out of universe that he's just a paranoid KnightTemplar putting innocents in danger for no good reason.
** [[ComicBook/LexLuthor Alexander Silversmith]] also tries to present himself as one, who does despicable deeds as part of a larger plan to make Equestria a better place. However, he's just a CorruptCorporateExecutive using it as an excuse.
* Averted in ''Fanfic/KyonBigDamnHero''. Koizumi absolutely refuses to use his new powers on unwilling subjects, seeking consent before experimenting on them, which makes it difficult for him to practice his powers.
* The [[spoiler: OriginalCharacter]] BigBad from ''FanFic/TheManWithNoName'' is this.
* In ''[[FanFic/SovereignGFCOrigins Origins]]'', a ''MassEffect''[=/=]''StarWars''[[spoiler:[=/=]''[=Borderlands=]''[=/=]''[=Halo=]'']] MassiveMultiplayerCrossover, Sarah [[spoiler:the Force-sensitive Siren]] falls into this category. Stopping an alien invasion that ends up taking over a galaxy and nearly taking over a second in the span of ''[[CurbStompBattle a few years]]'' may seem to cross the GodzillaThreshold, especially when the aliens in question are [[spoiler:the Flood]]. However, Samantha Shepard, et. al. take issue with killing hundreds of millions of people, or leaving the Terminus systems as a sacrifice to save Council Space--which [[AllForNothing doesn't even work in the end]].
* ''FanFic/ShepherdOfTheStars'', a ''Franchise/MassEffect'' and ''VideoGame/SwordOfTheStars'' FusionFic, features the Liir as these. After several years of slaver raids from the Batarians, their agents come to the conclusion that peace will never be possible and that Batarian culture will always cause them to attack their neighbors. So they try to [[FinalSolution completely exterminate]] the Batarians to keep them from [[ShootTheDog hurting anyone else.]] Only at the end of their attempted xenocide do the Liir realize that they've been duped by the same [[BigBrotherIsWatching information control]] the Batarians used on their citizens and that most of the Batarians they killed were decent people.
* The Order Triune in the ''Literature/TheDresdenFiles'' and ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' crossover fanfic ''FanFic/TheDresdenFillies False Masks'' see themselves as this. They seek to wipe out any trace of a reincarnated EvilOverlord called Obisidian. This is all well and good, until they've mistaken Harry Dresden, someone they've never even ''met'', as this reincarnated villain. In the process of trying to kill them, they've [[spoiler: kidnapped Twilight and Trixie, spied on many ponies, released a hydra that could have killed bystanders, and summoned '''He Who Walks Behind''' '''''TWICE''''', severely injuring the princess. In their final act, before they were themselves [[KarmicDeath sacrificed to summon a demon]] was to attack the Mane 6 and a disguised Princess Celestia to get to Dresden. When in turns out Obsidian ''never'' resurrected, Vigilant Watch, one of the surviving members of the Order Triune, is extremely remorseful for all her crimes, and is dismayed when she is let off so easily by Princess Celestia.]]
** [[spoiler: Novel Notion, who manipulated the Order into going after Harry, orchestrated their sacrifice, and planned to the same thing to the Mane 6 and Princess Celestia to become powerful himself, claims to be this, trying to create a society rule by ponies (specifically his own cohorts) by eliminating Princess Celestia and getting rid of the Order, and he totally unrepentant about it. While his reasoning for destroying the Order is pretty sound (it also made him what he was), and Princess Celestia admits that she is a tyrant, she also tells him that he would have killed many more ponies to cement his rule.]]
* ''Fanfic/SuddenContact'': The [[VideoGame/StarCraft Overmind]] seeks to end the [[Franchise/MassEffect Reaper cycle]] by assimilating the entire galaxy to present a united front against the Reapers.
* The Dumbledore from ''[[https://www.fanfiction.net/s/10964874/1/Dark-Dynasty Dark Dynasty]]'' is so desesperate for a powerful saviour he decides to abduct Cora's unborn child. Wiping the mother's memory is no big deal, because hey, she's a ''bad'' mother so she doesn't deserve a kid (okay, he's [[VillainHasAPoint kinda right]] but ''still''). And he manipulates Harry's life without remorse, as the kid shows a great potential for Dark magic, and it would be ''such'' a travesty to let another Dark Lord rise when you can force him onto the the proper way since the beginning, right?
* In the ''Manga/{{Bleach}}'' and ''VideoGame/WorldOfWarcraft'' crossover ''Fanfic/{{Transcendence}}'', the Bronze Dragonflight are understandably freaked out about Ichigo's unexplainable ability to permanently alter Azeroth's carefully maintained timeline simply by getting involved in events, leading to changes in time that the dragons can't predict. His presence has already led to the survival of both Adelina and Codexia, both of whom were supposed to die in the main timeline, and Anachronos foresees that Ichigo may completely derail the entire plan of events of Azeroth's future as they are supposed to happen, which in turn may lead to something cataclysmic. As such, they are determined to fix this before it goes any further. Unfortunately, their method of fixing the problem is to simply murder Ichigo when they find him. After all, he can't derail Azeroth's knowable future if he's dead, right? The worst part is that Ichigo doesn't know that he's somehow changing events at all, so he isn't even aware that the Bronze Dragonflight is actively hunting him. Thankfully, his summoning to Azeroth granted him some sort of seal that he's also unaware of that hides him from the dragonflight's ability to locate him through the timestream, meaning that the dragons have to find him the old-fashioned way, something they are having a very hard time doing.
* ''Fanfic/EarthsAlienHistory'':
** Torchwood, as per canon, is a black ops organization determined to protect humanity (and their allies) from potential threats no matter the cost. If that means unleashing chemical weapons on populated planets or breeding enslaved super soldiers, so be it.
** The Harvesters, as it turns out, aren't destroying planets ForTheEvulz. They deem it as a necessary evil to prevent life from evolving in a way that would bring back the Reapers, and/or enabling them to strengthen themselves for when the Reapers do come back.
** The Vinn parasitically possess people, turning them into drones. But this is for the sake of unifying the galaxy to take on the Reapers.

* The Astraea organization in ''FanFic/ACureForLove'', especially [[spoiler: V]]. When the original [[Manga/DeathNote Kira]] disappears they take it upon themselves to "cleanse the world" in his absence.
* ''FanFic/{{Fade}}'': L's StartOfDarkness is a combination of this and getting DrunkWithPower.

* Professor Osmond Stone from [[https://www.fanfiction.net/s/9830239/1/The-Sleeping-Survivors The Sleeping Survivors]] is kidnapping people to put them in suspended animation but does it out of a belief it will help humanity survive an alien attack.

* Alphamon in [[http://www.fanfiction.net/s/7623289/1/ Transcendence: Digital Curse]] seems to truly want to protect the Digital World. However, he believes that every problem that has endangered it originated within the real world. As a result, he wants to completely sever any links the two worlds have to each other. Gennai notes that if such a thing were to actually happen it could even destroy the digital world, but it's unknown if Alphamon actually knows this fact as well. So far, none of his actions seem to have contributed much to this goal. [[spoiler: His attempts to eliminate Agumon even seem to be just to spite humanity by stopping them from having a relationship with digimon.]]

* ''Fanfic/WalkingInCircles'': As in per canon, Solas is this trope with his goal of taking down the Veil and thus destroying the current world, along with many lives in it. But later, his lover Evelyn also becomes one due to her experience before and during the Mage Rebellion. Even Solasís taken surprised by her decision and he griefs for her loss of innocence to become like that.

* Fanfic/WhatChapter372OfFairyTailShouldHaveBeen: Unlike Kyouka who tortured Erza ForTheEvulz, Erza is torturing Kyouka because she believes she is punishing an evildoer, which she thinks is a noble thing.

* Generals Berg, Kristiani and Olafsen in ''Fanfic/WhatAboutWitchQueen''. Their plan has shades of InsaneTrollLogic ([[spoiler: ''start war with Weselton to prevent war with Weselton'']]), but they honestly believe that what they do is for the good of Arendelle, even if the queen clearly doesn't see it that way.

[[AC:''Disney'' in general]]
* The Master of Worlds from ''Fanfic/DisneysWarACrossoverStory'', the Master of Worlds at first seems one, as he invokes the UtopiaJustifiesTheMeans trope in his justifications, claiming that merging all the Disney worlds into one, removing all the troubles caused in the past by travels unbalancing the various worlds, would be a greater good for which the death of the magical beings is a lesser, necessary evil. However, TheReveal that [[spoiler: a much more nefarious force controls the Master of Worlds since the beginning]] pretty much proves that the Master of Worlds was not so "well-intentioned".

* In ''Franchise/HarryPotter'' fanfic [[http://www.fanfiction.net/s/4842696/1/Reparations Reparations]], Draco works in the St Mungo's Department of Magical and Chemical Dependence (Chem Dep for short), which is basically rehab for magic folk. Most of the patients are addicted to a wizard drug called [[FantasticDrug Chromia]], but there's also a new drug called Chromia X, which is stronger, more addictive and thus more dangerous than regular Chromia. It turns out that the department is constantly running the risk of being shut down because the [[ExecutiveMeddling the board]] doesn't understand its importance, so the head of the department, Draco's boss, creates and distributes Chromia X because he figures that if the number of patients increases, the board can't justify shutting down the department.

* ''FanFic/{{Hivefled}}'''s Lereal Belsai genuinely wants to do what's best for the warmbloods. Unfortunately, [[FantasticRacism he thinks this involves overthrowing and enslaving the coldbloods in turn]]. He also masterminds an attack in which all 250 of the ChildSoldiers of the Sufferist cult attack the thousands-strong Alternian fleet, relying on the protective magical powers Karkat Vantas has repeatedly and truthfully insisted he doesn't have.

* In ''Fanfic/{{Intercom}}'', one of Riley Andersen's classmates, a girl named Tracy, begins antagonizing her about HearingVoices (which for Riley are actually her emotions). While Tracy is a bully toward Riley, she ''does'' want her to get psychological help since it appears Riley has a mental illness that's getting worse by the day.

* Damballa in the ''FanFic/{{Horseshoes and Hand Grenades}}'' story ''A Month of Sundays'', [[spoiler: transformed Shotaro, Haruto and Eiji into {{Creepy Doll}}s because he has been trying to find a way to revive his own grandson who got lost in the struggle of the War of the Stars. Unfortunately, he's forcing the transformation on them, shattering their minds in the process and he truly cannot grasp the idea of a human mind. Thankfully, [[TheHeart Jun]] helps him see the light and reunites him with his grandson.]]

* In Fanfic/TheShroudedPath, [[spoiler: Vanitas]], the BigBad behind Franchise/SilentHill, is responsible for the torture (and often death) of the people who enter the town. However, he honestly thinks he is doing the universe a favour by ridding it of those people's evil.

* Hausmann in ''Machinima/ClearSkies'', who just wants to get his planet back. [[spoiler:When the battle with the Caldari fleet turns against him, he chooses to surrender rather than get any more of his people killed]].
--> '''Hausmann:''' [[spoiler:I came here to get our planet back, but I've lost more of my people in the last five minutes than in the last two years! No more!]]

* In ''FanFic/ChroniclesOfHarmonysEnd'', Array desires nothing more than to erase [[OrderVersusChaos his counterpart, Discord]] and considers backstabbing the TopGod (the only one keeping them - especially Discord - in line) a price worth paying for the chance. [[spoiler:[[NiceJobBreakingItHero He then proceeds to lose to Discord.]]]]
* ''FanFic/EquestriaAHistoryRevealed'':
** According to the LemonyNarrator, the canon version of Discord is an example of this, at least when compared to the "[[BlatantLies ultimate evil]]" of Celestia. Given she says this at the end of a chapter describing all that occurred during his Age of Chaos makes such a claim very questionable, especially when Celestia's regime doesn't seem to do anything as obviously destructive as his.
** In a more serious example, the former pegasus war hero Thunderhide is a clearer example of this, joining [[spoiler: Luna's side after losing faith in the Celestia-Equestrian system, and believing that joining her in destroying it is the only way true change can occur.]]
* ''FanFic/InnerDemons'': [[spoiler: Scootaloo]], having performed a FaceHeelTurn and joined up with Twilight (who herself had been consumed by her [[EnemyWithin Queen of Darkness persona]] and become the BigBad), is this mixed with TheStarscream. She admits that, unlike [[TheDragon Trixie]] and [[spoiler: Sweetie Belle]] (who both also had {{Face Heel Turn}}s around the same time she did), she's known all along what a monster Queen!Twilight is, and has only served her in order to get close enough to kill her and end her rule over Equestria. However (and this is where the Starscream angle comes in), she is ''clearly'' enjoying the pain and suffering she inflicts on the heroes, and more to the point, she has no intention of returning the throne to the Princesses -- once Queen!Twilight is dead by her hoof, she intends to set herself up as the great [[TheHero Hero]] who saved the day, and then take the throne for herself.
** After [[spoiler: her HeelFaceTurn]] she admits to having gotten DrunkWithPower and lost sight of her original goal.
* ''[[FanFic/RealityChecksNyxverse Nightmare Night and Nyx]]'': The conspiracy trying to eliminate Nyx are all convinced she's still evil and has brainwashed the Princesses, and thus has to be destroyed. [[spoiler: They all have a collective MyGodWhatHaveIDone moment when they realize how wrong they were.]]
* ''Fanfic/PagesOfHarmony'' also portrays Twilight as this. All she seems to want is for Harmony to reign in Equestria... which she plans to achieve through [[spoiler: performing torture and MindRape on her friends to extract their Elements, as well as anypony who gets in the way of her plans]].
* In the ''FanFic/PonyPOVSeries'', the second BigBad, Princess [[spoiler:Gaia, Fluttershy's SuperpoweredEvilSide]], is this. She only wants to create a utopia were no one suffers and everyone is happy...by ''brainwashing'' everyone into being happy and [[spoiler:[[FountainOfYouth turning every pony into foals in both mind and body.]]]]
* ''[[FanFic/PoniesOfOlympus Rolling in Beaches]]'': King Kenbroath and his clan honestly believe that ponies are descended from cursed dragons (it's actually the other way around) and that they must use the Rainbow Pearl to revert it. He doesn't care to ask anypony's permission first because he figures granting them all substantially longer lives and great power would be a blessing.
* ''FanFic/SlyWitsParadise'' has the Unicorn chief Phantom Spell. He is an autocratic Unicorn chief stallion, is very (large emphasis on "very") strict on his orders and rules and has zero tolerance on misbehaviour and internal conflict, but he did so to keep his herd safe from the frequent dangers of the Everfree Forest where they live in (such as the Ursa Major that passed through the Unicorn territory later).
* ''Fanfic/{{Misunderstandings}}'': The conspiracy against Peter Collins, a human who ends up Equestria, is actually a subversion but in different ways. For many of the nobles out to get Peter, it is subverted on the "well-intentioned" part. They seek to target Peter, but only because they see him as a way to discredit Princess Twilight in the eyes of Princess Celestia and seek other personal gains, and show almost no concern for who gets hurt in the process. For Sergeant Peppermint York, it is subverted on the "extremist part". She genuinely believes Peter is a dangerous monster [[spoiler: and in all fairness Peter did almost fatally shoot Aircolt Swift Wind]] but is unwilling to hurt other ponies to get to him, and finds herself more and more [[EvenEvilHasStandards infuriated by the actions of the conspirators which have endangered lives]] than with Peter being free in general. [[spoiler: When Peter is proven to be totally innocent of any wrongdoing, she confesses to the role she played.]]
* ''Fanfic/RainbowFactory'': The workers want to keep Cludsdale full of Rainbows, which are an important part of their society. [[spoiler:They do this by killing failed fliers, all of them children]]. Though depending on the version you are reading, there are hints that they have other reasons for [[spoiler: [[ANaziByAnyOtherName killing the "weaker" children...]]]]
* ''FanFic/{{Asylum}}'':
** Dr. Rose, Twilight's doctor who uses highly questionable methods, but it is to make sure that no unicorn ever has to be "cured" by a Keratotomy[[note]]A procedure that lobotomizes unicorns by removing their horns and a good chunk of their brains[[/note]]. Or at least, that's what claims. Just like most things in ''Asylum'', it is hard to say if this is true or just a lie used to cover a much more sinister motive.
** Arguably Twilight as well, as she repeatedly uses manipulative tactics and other morally questionable actions that could harm her own friends to try to prove herself right, but only because it's what she believes has to be done to save Equestria.
* ''Fanfic/TheLifeAndTimesOfAWinningPony'': In ''The Lunar Rebellion'', Ephor Swift Blade is essentially one such extremist who got his facts wrong. He truly, honestly believes that Celestia is a tyrant, that Nightmare Moon was a better leader who was banished unjustly and should be returned to power, and that Equestria would be genuinely better off as a Pegasus-run military dictatorship. He's wrong, of course, but even if he were right, that still doesnít excuse [[spoiler: allying with [[BadPowersBadPeople warlocks and lunar cultists]], violently overthrowing other governments, and using [[HumanSacrifice equine sacrifices]] and BloodMagic to turn a fellow ephor into the Avatar of Nightmare Moon.]]
* ''[[https://www.fimfiction.net/story/79743/love-in-all-its-forms Love, in All Its Forms]]:'' Celestia banishes her niece, Luna's changeling daughter Antumbra, to a desert wasteland, to stop her from draining Luna dry of all love and accidentally killing her. She then lies to Luna that Antumbra is dead to keep her from searching for her daughter. The story has NoEnding, leaving readers to decide whether or not Celestia was justified in her actions.
* ''[[https://www.fimfiction.net/story/162801/best-friends-forever Best Friends Forever]]'' (written by the same author as ''Love, in All Its Forms''): After Fluttershy died of old age, Twilight, not wanting to outlive her remaining friends, devised a method to keep them immortal by isolating them and herself in a castle, magically regressing them into babies and having them live out their lives with her, then turning them into babies again when they get too old. According to Twilight, they weren't happy being regressed at first, but "came around" eventually.

* Ho-oh from ''Fanfic/PokeWars'' wants Pokémon-kind to live in a utopia. He plans to achieve this utopia by engaging in a genocide against humanity. [[spoiler: He later goes JumpingOffTheSlipperySlope by doing things like ordering wanton killing of Pokémon, contrary to his ideals, utterly ruining the environment and not giving a damn about it, and generally being a filthy hypocrite.]]
* The Sky Soldiers from ''[[https://www.fanfiction.net/s/9495178/1/Return-of-the-Hero Return of the Hero]]'' just want to rid the world of all evil...at the cost of Ho-Oh's life and unleashing Pure Impurity, which would result in the destruction of the entire universe.

* ''FanFic/RosarioVampireBrightestDarkness Act III'': When Akua and Kahlua are revealed to be working for Kiria and participating in his plan to [[TimeTravelForFunAndProfit use the Chrono Displacement spell to change history so monsters rule the world]], they insist they're doing it for their father Issa, wanting to make him one of the top dark lords of the Earth once humanity is subjugated. However, in doing so, they killed their father's servants and stole the Chrono Displacement spell from the Shuzen family archives in the first place, and it all turns out to be for nothing when they discover that Kiria's plan would have put him in place as the only dark lord of the world, and [[NotWhatISignedOnFor part of said plan would be Issa's death]].

* In ''FanFic/ClashOfTheElements'', Joe Dark [[spoiler: THINKS]] he is one of these, but as Alex points out to him [[spoiler: after learning of his backstory]], his ends don't really justify the means.
