->''"I never deal with what I am. I don't think about it. I just do my job, which usually involves me beating the crap out of things a lot like me. But I don't think about that."''
-->-- '''ComicBook/{{Hellboy}}'''

A trope very common for your {{Dhampir}}, FriendlyNeighborhoodVampires, or [[VampireDetectiveSeries Vampire Detective]]. This is where you have Group X which is AlwaysChaoticEvil. Then there's Character Y, who somehow has the powers of Group X but has a conscience, often because he or she is a PhlebotinumRebel or a HalfHumanHybrid of WarringNatures. So, Character Y becomes TheHunter, allowing him to use his BadAss powers for a good cause. Sometimes, this turns out badly for TheHunter when it is revealed that his targets actually aren't totally evil, and a case of VanHelsingHateCrimes can result.

For [[IHateYouVampireDad some reason]], vampires seem particularly prone to doing this. Maybe it's because they like to turn their [[TheHunter enemies]] out of spite.

!!Examples:

[[foldercontrol]]

[[folder: Anime and Manga]]
* VampireHunterD is one.
* Abel Nightroad of ''TrinityBlood'' is a crusnik, a vampire who hunts and eats other vampires.
** Although it is implied (in the anime) by their dialogue that the Crusnik see themselves as another race entirely, they do need the blood of vampires to survive. Abel is the only one [[spoiler: of the three]] who actually makes it a point to hunt vampires. [[spoiler: His sister]] isn't shown to hunt anyone (in fact, [[spoiler:she's the empress of the vampires]]), and [[spoiler: Cain]] doesn't care who he hunts/hurts.
* Alucard and his fledgling Seras Victoria from ''{{Hellsing}}''. Alucard is an interesting case; he's frequently as bad or ''worse'' than the vampires he's hunting (''[[EvenEvilHasStandards maybe...]]'') and takes far too much glee in killing them, often getting [[FamilyUnfriendlyDeath 'creative']] in his methods.
* The Shikabane Hime of ''ShikabaneHime'' are undead girls who hunt and kill other undead.
* Both Robin and Amon in ''WitchHunterRobin'' are witches who hunt other witches.
* Setsuna in ''MahouSenseiNegima'' is a half-demon who hunts demons. They asked for it, however, by kicking her out for her [[HeroicAlbino albinism]].
** Similarly, [[spoiler: Mana Tatsumiya]] is also a half-demon who specializes in exorcisms.
* [[spoiler:Yusuke]] in ''Manga/YuYuHakusho'' ends up being one when it's revealed he has a little demon in him towards the end of the series.
** Hiei also qualifies. Ever since he could walk, he's been brutally slaughtering demons left and right, all because he enjoyed killing. Although for a time, his primary motivation was to kill all the ice maidens from his birthplace.
* [[spoiler: Darcia]] in ''WolfsRain'' is a villainous example, hunting the wolves despite being part wolf via a traitorous bloodline.
** Blue Yaiden is one ''unwittingly.''
* The main character in Kei Kusunoki's ''OgreSlayer''.
* In ''{{Macross}}''[=/=]''{{Robotech}}'', [[http://en.wikipedia.org/wiki/Milia_Fallyna_Jenius Milia]], a Zentraedi (or is that Meltran?) who is [[ArchEnemy obsessed with defeating]] the human ace [[http://en.wikipedia.org/wiki/Maximilian_Jenius Max]]. When she is captured by Max, not only does she do a FaceHeelTurn, she becomes his partner fighting the Zentraedi, but tends to [[VanHelsingHateCrimes shoot down her opponents with nonlethal shots when possible]].
* In ''Manga/FullmetalAlchemist'', the assassin Scar only targets alchemists, despite using alchemy himself.
** Of course, Scar never identifies himself as an alchemist (as his religion considers it a sin) and brushes it off when people point out that his arm performs alchemy. [[spoiler:He gradually overcomes this]].
** And [[spoiler:Greed]] spends quite some time fighting other homonculi after his HeelFaceTurn.
* [[spoiler:Rei Ayanami]] of ''Anime/NeonGenesisEvangelion'' is an artificially created Angel/Human hybrid who pilots an Evangelion to fight Angels.
** And of course, [[spoiler:the [=EVAs=] themselves are reverse engineered from the first two Angels]].
* Dark from ''DNAngel'' was described as such by Argentine.
* Zero from ''VampireKnight''.
* Saya from ''Anime/BloodTheLastVampire'', ''Anime/BloodPlus'', and [[AmbiguouslyHuman possibly]] ''Anime/BloodC'' [[note]][[NamesTheSame different girl, mind you]][[/note]].
* Nagasawa from DawnTsumetaiTe is immune to the worst effects of [[TheCorruption Nightshift]], whose [[BodyHorror not-so-fortunate victims]] he must hunt down and kill using the very mutations that the Nightshift has given him. [[GenreSavvy He knows it, too.]]
* Both Merry and Engi from ''YumekuiMerry'' are nightmares who hunt other nightmares. That said, Merry just sends them back to the dream world, and Engi tries to avoid killing them, letting Merry finish the job when possible.
* [[AntiAntiChrist Rin]] from ''Manga/BlueExorcist''. Mephisto even lampshades this in a recent chapter.
* [[spoiler: Natsuno]] aids in the efforts to stop the vampires infesting Sotoba Village in ''{{Shiki}}'', ultimately [[spoiler: killing TheDragon and himself in the process]].
* The Rogue Titan from ''Manga/AttackOnTitan'', as it attacks other Titans while ignoring the nearby humans. [[spoiler: This is because it's actually Eren, on a RoaringRampageOfRevenge after his VoluntaryShapeShifting powers manifested. Armin successfully invokes this trope, convincing the military that Eren can become their trump card in the battle to reclaim first Wall Rose, and eventually Wall Maria from the Titans.]]
** [[spoiler: Ymir also becomes this, when her unarmed squad is cornered in a castle tower by a horde of Titans. WordOfGod confirms her decision to reveal herself and fight is because she's in love with Krista. She gets overhelmed, but luckily the Survey Corps [[BigDamnHeroes arrives in time to save her.]]]]
* I think Carl Van Helsing from Crimson Cross counts.
[[/folder]]

[[folder: Comic Books]]
* Andrew Bennett, from DCComics' "I, Vampire" series in ''HouseOfMystery'', was a vampire determined to hunt down the line of evil vampires which [[WhatHaveIDone he himself had started]].
* {{Blade}} is a {{Dhampir}} vampire hunter. Him being part vampire, the thing he hates the most has caused him no small amount of grief.
** [[ComicBook/UltimateSpiderMan Ultimate]] ComicBook/{{Morbius}} is a true vampire and Vlad the Impaler's brother. It is implied that he was the inspiration for Bram Stoker's ''Literature/{{Dracula}}''.
* If you want a not-so-sunny example of this trope, look at {{Lobo}}. He hunted down and killed every single member of his own race. For fun.
* ComicBook/{{X-Factor}} began as a team that hunted down mutants. The general public didn't know that the team members were mutants themselves and [[spoiler:that they were actually trying to help the mutants they "hunt" down]].
** The ComicBook/{{X-men}} in general fight evil mutants quite often when they aren't fighting anti-mutant racists.
** Would you believe that Sentinels are mutants themselves? Seriously, some people who build them (like Sebastian Shaw) have tried to put a failsafe program into them to use in case they go rogue, which reveals that, since their abilities were "inherited" and improved upon from from the original Mach-1 Sentinels, they are techincally mutants. In theory, this would act as a LogicBomb, causing a rogue Sentinel who has this revelation thrust upon it to destroy itself, as its directive is to destroy mutants. However, this idea hasn't had as much success as whoeveer thought it up had hoped.
* {{Venom}} was like this. One of the few reasons he'd [[EnemyMine willingly ally himself]] with SpiderMan was to fight Carnage or another Symbiote; he simply ''hated'' them. This became a far-more prominent goal when he later became Anti-Venom.
** In fact, this seems to be a trait of Symbiotes in general. The one time Venom and Carnage were ''ever'' willing to cooperate with each other was to fight a more powerful Symbiote that had been spawned from Carnage's Symbiote.
[[/folder]]

[[folder:Fanfic]]
* Many a MarySueHunter can fall into this by accident - one of the main criticisms of the genre (beyond "WHY DID YOU KILL MY CHARACTER I HATE YOU") is that said Hunters often end up being {{Mary Sue}}s themselves.
** If you think about it having a character beat an over-idealized character as such a MarySue (with the exception of AntiSues) has a high probability of accidentally becoming one him-or-her-self because having beaten an over-powered character requires you to be even more powerful or extremely lucky. A way to around this can be to have them have a hard time at first and work hard to defeat the {{Mary Sue}}(s) or {{Marty Stu}}(s) & then succeed.
[[/folder]]

[[folder:Film]]
* According to one version of ''Film/BladeRunner'', the main character who hunts rogue androids is an android himself. If true, this is a rather dark spin on the trope. Basically, androids are detected by being tested for moral feelings and reveal themselves to be amoral. As the androids turn out to be [[TinMan "tin men"]], this would mean that he is actually worse than his targets. The amorality is explained as resulting from lacking real childhoods and formative years of experience. There is at least one android in the film (two if you count the main character) who has/have memory implants of growing up with a family and loved ones (even if those loved ones died or left). They both show that they have a sense of right and wrong and the definite android is only exposed after hundreds of times more testing than any previous android.
* Film/{{Hellboy}} is a demon who fights other demons and supernatural monsters. Sometimes, the creatures he fights accuse him of betraying his kind, but he seems to be more worried about becoming like them.
** ''HellboyII: The Golden Army'' uses this in the opposite manner from the comic books--to make the monsters that HB fights more sympathetic and to make HB resign from the BPRD.
** Notably, in the first movie, he attempts to negotiate with the demon Sammael before resorting to violence.
[[/folder]]

[[folder:Literature]]
* [[TheLegendOfDrizzt Drizzt Do'Urden]] from ''ForgottenRealms'' is another poster boy contender considering how badly he breaks his vow to never kill drow elves.
** He discards the vow in the third group of books after realizing it's stupid to kill goblins and other evil monsters, but not drow.
** His father too. More coherent than Drizzt, Zaknafein ''prefers'' to kill drows, because they are the most cruel creatures he knows.
* While we're at it, Jander Sunstar from ''ForgottenRealms'' and ''{{Ravenloft}}'' is yet another vampire hunter vampire.
** Also from ''{{Ravenloft}}'', Ivan Dragonov has continued to hunt monsters after contracting lycanthropy himself, using his bestial form as a weapon of last resort.
* This backfired ''badly'' in the backstory of the sci-fi novel ''Candle'', although it only becomes apparent towards the end. [[spoiler:As one HiveMind after another ravaged the world, seeking only to [[TheVirus add more members to their ranks]], a benevolent hive mind was created to protect the minds of those in it. It, too, sought to spread itself, initially as a counter to the other hive minds, [[JumpingOffTheSlipperySlope until at last it became no different than them]]]].
* The eponymous NightHuntress, at least at first.
* ''Literature/NightWatch''. Both Light and Dark Others persecute their kindred who break the Treaty and threaten to disrupt the Balance between Light and Darkness. Also invoked in that in order to hunt down renegade vampires, Night Watchers need to tune in to the [[CompellingVoice "Call"]] they use to attract victims. It is only audiable to other vampires, so the Watchers undergo a special ritual that nearly turns them into a vampire.
* The protagonist of Richard Morgan’s “Black Man” (“Thirteen “ in the U.S.) is a pretty good example of this.
* The White Council and its Wardens in ''Literature/TheDresdenFiles'' have distinct shades of this. While wizards aren't considered ''inherently'' evil (after all, the Council is itself a wizardly organization), breaking the Laws of Magic even once carries a death penalty and ignorance of said Laws is not considered an excuse. Of course, at least according to the Council Lawbreaking ''is'' a highly slippery slope that is [[JumpingOffTheSlipperySlope easy to jump off of]]...
[[/folder]]

[[folder: Live-Action TV ]]
* Athena from the 2000s ''Series/{{Battlestar Galactica|Reimagined}}'' is a Cylon who fights against other Cylons. And then there's [[spoiler:Tigh, Tyrol, and Anders]] who were fighting against the Cylons for years, [[TomatoInThemirror unaware of their true nature]].
* The title character of ''Series/{{Angel}}'' is a vampire who hunts other vampires, and the character Spike also fits this description. When Angel first meets Buffy in ''Series/BuffyTheVampireSlayer'' he tells her that what he wants is to kill them, to kill them all. It turns out that he wants to kill them to make up for his own monstrous actions.
** Spike initially inverts some parts of the trope since he starts out fighting vampires and demons not because he wanted to be good, but because he could no longer attack humans and [[BloodKnight REALLY missed violence]].
** Angel's {{Dhampyr}} son Connor takes this and runs with it. Not only did his adoptive father teach him to fight vampires and demons, he groomed him to fight his biological father.
* Examples from ''Franchise/KamenRider'':
** In ''Series/KamenRiderFaiz'', [[spoiler:[=Faiz/Takumi=] is actually the wolf Orphenoch.]]
** In ''Series/KamenRiderKiva'', [[spoiler:Wataru is part Fangire, making him sort of a {{Dhampyr}}.]]
** In ''Series/KamenRiderOOO'', [[spoiler:Eiji does not start this way, but he slowly becomes a Greeed near the climax of the series.]]
** In ''Series/KamenRiderWizard'', [[spoiler:It's double-subverted with the Dragon Phantom. Haruto (Kamen Rider Wizard) summons it to fight against unreleased phantoms, but still need to control it in order to do so. Afterwards, though, the phantom decided to lend Haruto its own power.]]
* Eric Cord from ''Werewolf'' did this for the entire series.
* Ruby on ''Series/{{Supernatural}}'' is a demon who fights other demons and helps Sam fight them. Sam is arguably another example of this trope, because his PsychicPowers are caused by having been fed demon blood. Of course, it turns out [[spoiler: Ruby is among the worst of the lot and was driving Sam to his destiny to release Lucifer from his prison. [[NiceJobBreakingItHero Which he did]]]].
* In ''TheSarahConnorChronicles'', [[RobotGirl Cameron]] is frequently tasked with hunting and destroying other Terminators. Most often, she does this to protect others, but one episode involves her going into full-on detective mode to track down a Terminator she discovers entirely by accident, and then destroying it.

[[/folder]]

[[folder:Music]]
* [[http://www.jamendo.com/en/track/125694 "Princes of the Dreams"]] by Doug the Eagle ("[[TomatoSurprise So you've just discovered you're a soul-eating monster...]]")
* In the music video for the song A Little Less Sixteen Candles, A Little More Touch Me by {{Falloutboy}}, the bassist Pete Wentz is a vampire while the rest of the band are humans who all hunt vampires.
[[/folder]]

[[folder: Tabletop Games ]]
* Martin [=DeVries=] of ''TabletopGame/{{Shadowrun}}'' deliberately became a vampire in order to hunt them on their own terms.
* One of the potential racial backgrounds for the Shardmind in [[DungeonsAndDragons D&D]] 4e is Shard Slayer, a Shardmind which believes that, since their kind was born from shards of the living gate, then a dead Shardmind's life force returns to it and mends the gaps that allows the influence of the Far Realm to seep through. This mentality is taken to a logical extreme as Shard Slayers hunt down and kill other Shardmind and destroy unawakened shards in the hopes of closing the gate back up.
** The Ranger class has the Favored Enemy ability, where the character chooses one or more species and gains several benefits fighting that species. Only an evil Ranger can choose their own species, however, in which case they qualify for this trope.
** In ''Van Richten's Guide to Witches'' (an accessory for the ''{{Ravenloft}}'' campaign), the good doctor claims that he wrote the book with the help of a greenhag who despised other members of her species and was all to willing to aid him in publishing a book that could be used against them. (Why? According to Van Richten, she refused to say.)
* A few examples from [[TabletopGame/NewWorldOfDarkness the World of Darkness]]:
** ''TabletopGame/VampireTheRequiem'' has VII, a mysterious group of Kindred who, for some unknowable reason, kill other vampires. Their minds can't be read and they can't be interrogated. Most vampires regard them as an urban legend; however, they do have a book that offers three possible backstories.
** ''TabletopGame/MageTheAwakening'' has Banishers, mages whose Awakenings went [[MindRape horribly, horribly wrong]]. As a result, they view magic as something filthy and wrong with the world (they can't use it without feeling innate revulsion) and spend most of their time hunting down other Awakened and killing them to try and "heal" the world in their own way.
** ''TabletopGame/HunterTheVigil'' has the Lucifuge, a conspiracy made up of those who believe they carry the blood of Hell in their veins. They spend their days fighting against demons, their brethren who went over to the side of the Devil, and things darker still.

[[/folder]]

[[folder: Video Games ]]

* Alucard from ''Franchise/{{Castlevania}}'' definitely counts, being heavily inspired by D.
* Rayne from ''VideoGame/BloodRayne''.
* Full-blooded demon Sparda in the ''VideoGame/DevilMayCry'' back story turned against his fellow demons and sealed them in their own world. His son Dante, a half-demon himself, carries on by hunting demons who sneak into our world.
* In ''SidMeiersPirates'', you have the option of only going after other pirates if you so choose.
* [[spoiler:Adell]] in ''VideoGame/Disgaea2CursedMemories''. Of course, [[spoiler:he's unaware that he's not human]].
** And Sardia the demon slayer in the first game.
** The Prinny Extermination Squad in ''[[VideoGame/Disgaea4APromiseUnforgotten A Promise Unforgotten]]''. [[spoiler:They were supposed to be prinnies themselves, but there were too few skins to go around. This applies to their latest recruit, Fuka Kazamatsuri, as well.]]
* The main character in the game ''VideoGame/DivinityIIEgoDraconis'' is on their way to being initiated as a full dragon slayer when they get turned into a dragon. Your dialogue options allow them to protest this and act as if they are still a slayer [[spoiler:until the slayer commander and their slayer buddies attack the main character]].
* Ashrah of the ''MortalKombat'' series is a demon who wields a holy sword that purifies her bit by bit with every one of her fellow demons that she kills. She hopes to become completely purified and holy this way.
* Pretty much the biggest {{reveal}} for ''VideoGame/MegaManX'' is that [[spoiler:Zero]] is the ''original'' Viral Maverick (meaning that TheVirus originally came from him). Not only is this fitting for the trope, it also makes him the [[TheAtoner hunter of the race he unwittingly created]].
** [[TheHero X]] himself qualifies, since all Reploids (Repliroids, based on X's designs) and, by extension, Mavericks/Irregulars stem from him.
* Karg from ''VideoGame/ArcTheLad 4'' says that he is going to do this when he finds out that he is a HalfHumanHybrid, but he decides not to later.
* [[spoiler: Balthazar]] from ''BaldursGate II: Throne of Bhaal''. He knows the Bhaalspawn aren't AlwaysChaoticEvil, but thinks they're still too dangerous, and he intends to kill himself last in a ritual designed to stop this from bringing Bhaal back. He actually works with some of the other powerful Bhaalspawn because they want to kill all the others ''except'' themselves.
* Alex Mercer spends most of ''VideoGame/{{Prototype}}'' killing the viral monsters controlled by Elizabeth Greene, [[spoiler:including Greene herself]]. Alex qualifies because [[spoiler:he ''is'' the virus.]]
* If he befriends or becomes the lover of The Warden in the original ''VideoGame/DragonAgeOrigins'', [[ProfessionalKiller Zevran Arainai]] becomes one of these in ''VideoGame/DragonAgeII''. In the seven years between the end of the first game and the point at which Hawke meets him in the second, he has sown chaos in the ranks of his former employers, the [[MurderInc Antivan Crows]], managing to assassinate one of the seven Guildmasters while simultaneously forging an alliance with two more as well as several other disaffected assassins.
** The Grey Wardens technically qualify, as becoming a Warden involves [[spoiler: drinking Darkspawn blood and taking [[TheCorruption the Taint]] into themselves, turning them into a type of high-functioning [[OurGhoulsAreDifferent ghoul]] with their [[ProHumanTranshuman humanity intact]]]]. This also allows Wardens to permanently kill the Archdemon by [[spoiler: forcing its soul to BodySurf into them at the moment of death, [[TakingYouWithMe destroying them both]]]].
** A Mage Hawke in ''VideoGame/DragonAgeII'' frequently finds themselves hunting down Blood-Mages, [[TheReasonYouSuckSpeech berating them]] for their WellIntentionedExtremist actions and pointing out that it's only made the situation ''worse'' and caused innocent Mages to suffer at the hands of certain Templars who see little difference between [[LaResistance Apostates]] and [[EvilSorcerer Maleficarum.]]
** Played straight if a Mage Hawke ends up being Templar-Aligned at the end of the game. If still alive, Carver will [[WhatTheHellHero call them out]] on this and points out that if [[DeadLittleSister Bethany]] was still alive, Hawke would be turning against ''her'' as well.
** Bethany can be convinced to do this in the Templar Ending by a Warrior or Rogue Hawke, although she's ''[[WhatTheHellHero not]]'' happy about it and only agrees because innocent people are being killed in the crossfire.
* Demon hunters in ''VideoGame/{{Warcraft}}'' study and use fel magic in order to more effectively hunt demons. Since the magic is innately corrupting, many of them become partially demonic themselves and may or may not retain their original noble intentions.
** Death Knights, former slaves of the Lich King, use their knowledge of necromancy and Scourge tactics to fight the undead in Northrend. A lot of the more vengeful Forsaken fall into this category as well.
** Wrathion is a black dragon that, due to the unique circumstances of his birth, is free of the Old God corruption that has taken over the rest of the Black Dragonflight. He's on a crusade to eliminate the tainted black dragons, and the rogue legendary Fangs of the Father questline is centered around helping him do this. By the end of the quest, he claims to be the LastOfHisKind, though observant players have noticed [[WhatHappenedToTheMouse there is at least one other black dragon (Sabellian) unaccounted for]].
* The Dragonborn in ''VideoGame/TheElderScrollsVSkyrim'' is a mortal with an Aedric dragon soul who fights other Dragons. [[spoiler:The trope is played even straighter in the ''Dragonborn'' DLC, when the Dragonborn is forced into a confrontation with [[EvilCounterpart Miraak]], the First Dragonborn]].
** If you choose to side with the Dawnguard vampire hunters against Lord Harkon in the ''Dawnguard'' DLC, Harkon's daughter Serana will join you and eventually be permitted to take up residence in the Dawnguard's headquarters. She ''can'' be convinced to cure herself of vampirism... but only if you say the right things, and only ''after'' Dawnguard's main quest.
** If the Dragonborn is a Vampire or Werewolf, this trope can occasionally come into play. Defied in ''Dawnguard'', as Isran will frequently chastise and refuse to deal with a Vampire Dragonborn until they cure themselves.
* In ''DarkSouls'', the most common enemies the Chosen Undead will encounter are other Undead who have long since gone Hollow and insane.
* ''Off-Road Velociraptor Safari.'' The driver is a velociraptor [[RuleOfCool for no particular reason]]. Its motivation is not really explored, but the way it is beamed away when time runs out suggests it may just have [[TheLastDance nothing left to lose]].
* Raziel in ''LegacyOfKain'' is a three-fold example. A [[spoiler:former Sarafan vampire-hunter, resurrected as a]] vampire, he was betrayed by Kain, the vampire who sired him, and executed, then reborn as an ethereal wraith and accepted an offer from the [[EldritchAbomination Elder God]] to become an Angel of Death. His purpose is to hunt down and destroy the vampires who were once his brothers, but he also hunts and kills other ethereal beings, [[spoiler:as well as members of the Sarafan Order,]] at times.
* Subverted in ''VideoGame/LeagueOfLegends''. Miss Fortune is a pirate hunter because her mother was killed by pirates, but her attire is completely pirate-like. A PirateGirl? Nope, she's just dressing up like one, she's a full time pirate hunter.
** Played straight with Vi, however. She was once a normal criminal, but then found a set of PowerFist in a mine. Afterwards, she redirects her passion into hunting down other criminals by punching them in the face, before becoming an official police in Piltover.
* In ''VideoGame/ImmortalSouls'', Raven had herself turned into a vampire specifically so she could take revenge on the vampires that killed her family and is well-known for her enthusiasm about the matter.
-->'''Raven:''' You wanted to see me, Isis?
-->'''Isis:''' Indeed, Raven. I have a new mission for you.
-->'''Raven:''' Do I get to kill vampires?
-->'''Isis:''' Still holding a grudge against your own kind?
-->'''Raven:''' Always.
* ''DwarfFortress'' has the legendary [[http://dwarffortresswiki.org/index.php/Cacame_Awemedinade Cacame Awemedinade, The Immortal Onslaught]]. An elven resident of a dwarf-conquered civilization, his wife was killed [[ImAHumanitarian and eaten]] by other elves. He later ended up becoming an Elven King of Dwarves, seemingly out of [[ScrewYouElves pure burning hatred of the pointy-eared ones]].
* In the backstory of ''Videogame/{{Darksiders}}'' and its [[Videogame/DarksidersII sequel]], the Four Horsemen were the only Nephilim who believed the Nephilim's campaign of universal conquest was wrong. The offered their services to the Charred Council to help set things right. The newly christened Horsemens' first order was to slay the rest of the Nephilim.
* The vampire twins Vania and Veight, as well as the player (who gets vampirized by them) in the "Memories of the Dark" event in the mobile trading card game ''VideoGame/RageOfBahamut''.
* ''VideoGame/SaintsRowTheThird'' features a cheesy ShowWithinAShow called ''Nyteblade'', about a vampire hunter who was turned into a vampire himself.
* In ''VideoGame/SwordOfTheStars'', the Liir's greatest weapon against the dreaded Suul'ka [[spoiler:power-mad Liir Elders who enslaved the rest of the Liir so they could live forever in space]] is The Black [[spoiler:another Liir Elder who lives in space like the Suul'ka.]]
* ''Videogame/InfamousSecondSon'' has the D.U.P., CapeBusters led by Brooke Augustine, a Conduit who has bestowed her [[DishingOutDirt concrete-based]] powers to the rest of the group.

[[folder: Visual Novels ]]

* Arcueid from ''{{Tsukihime}}'' took this trope to its logical conclusion, making herself the LastOfHerKind.
** Also in ''Tsukihime'', the head of the Tohno family has the obligation to find and kill any family members who succumb to [[TheDarkSide their demonic blood]].

[[folder: Web Comics ]]

* Sam from ''Webcomic/SluggyFreelance'' is a vampire who often fights other vampires. Mostly because [[GenreSavvy chicks think it's cool]].
* [[spoiler: Shadowchild]] from ''{{Shadowgirls}}'' [[spoiler: is an EldritchAbomination created by one of the [[CthulhuMythos Outer Gods]] with the purpose of fighting other Eldritch Abominations, and even Elder Gods]].
* Othar Tryggvassen, '''GentlemanAdventurer!''', from ''Webcomic/GirlGenius'', is a Spark on a quest to kill Sparks (eventually even the good ones, but for now just the bad ones). He's even outright stated that after he rid Europe of all the other Sparks, he'll end his own life just to ensure that the Spark is no more.
** On [[http://www.girlgeniusonline.com/fun/twitter_othar_01.php meeting]] his ''{{doppelganger}}'':
---> A puzzler. All Sparks must die, yet I am a Spark. I will kill myself when my mission is complete, but now I can kill myself first. Tempting.
** Also, in the card game, there is a "vampire hunter" character that ironically is the only card that counts as "vampire".
* In ''{{Chirault}}'', Kiran is a demon and employed by the demon hunter guild. That said, in ''Chirault'', "demon" is a pretty broad term, and Kiran's "species" of demon (horned humanoids) seems pretty rare. Many of the demons that Kiran kills seem to be non-sapient.
* In ''WereGeek'', Joel attempted to turn one of the Hunters into a geek, with somewhat predictable results.
* ''[[http://www.ringtailcafe.com/starfireagency/ Starfire Agency]]'' had Timothy Madoc, a vampire hunter who was turned as a sort of sick joke. He and his living siblings made a pact that when they wiped out every other vampire on the planet they would slay him. Unfortunately he outlived the rest of them by several hundred years, and eventually he actually became an enforcer for the vampire council after they banned killing mortals. And he's the "uncle" of main character Alexandra Maddock.
* Ryo from ''HeartCore'', a demon hunter from [[DomedHometown New Ayers.]] The story heavily implies that she is a demon herself, being able to sence their precense from long distances and surviving falling off a skyscraper. Her reasons for killing demons are not yet fully known.

* ShowWithinAShow example from ''LookToTheWest'': one of the seminal works in that world's "[[SteamPunk Automaton fiction]]" craze of the 1820s-1850s period is ''The Venator'', about a KillerRobot whose role is to hunt down and kill the last of his own rebellious kind and, once this is accomplished, to [[NoPlaceForMeThere dismantle himself]].
* Dr. Alto Clef of the ''Wiki/SCPFoundation'' is a RealityWarper[[note]]or at least is totally immune to the powers of RealityWarpers[[/note]] who is committed to using his powers only to get rid of other reality warpers.
** Assuming that [[http://www.scp-wiki.net/scp-349 SCP-349]] is the work of one person, that person is an immortal who hunts and kills immortals who started out mortal and purposfully became immortal.

* In ''FernGully'', Zak, the human, plays this role for the nonhuman locals, though he [[VanHelsingHateCrimes doesn't actually hurt anyone]]; he just tries to stop them.
-->'''Zak:''' Guys, things have got to change.
* WesternAnimation/DannyPhantom is a half-ghost who fights other ghosts.
* ''GeneratorRex'', Rex being an EVO, is employed to fight [=EVOs=].
** This trope is actually [[PlayedWith played with]] because everyone on Earth, [[spoiler: except White Knight,]] is infected with nanites, the things that cause people to turn into [=EVOs=]. That means ''everyone'' at Providence is hunting down their own kind and anyone of them could randomly turn into one at ''anytime'' without warning.
* In the {{Backstory}} of ''WesternAnimation/AdventuresOfTheGalaxyRangers'', Shane Gooseman was the youngest and most advanced of the ArtificialHuman [[{{Tykebomb}} Supertroopers]]. When the 'troopers rioted, Shane was the only one to remain loyal. However, the Earth Government only allowed him to live on the condition that he hunt down and kill his renegade ex-comrades -- or bring them back to Earth to be sent to their deaths in cryo. Shane hates this hellish bargain, but can't see a way out.
* Slimer from TheRealGhostbusters is a ghost that lives with the Ghostbusters and helps them against other ghosts from time to time (i.e., almost every other ghost in the ContainmentUnit was caught with Slimer's help).
* In ''ScoobyDooMeetsTheBooBrothers'', the Boo Brothers are ghosts that work as ghost exterminators. They claim that that's the whole point. ("It takes one to catch one in this business," they claim.)
* ''WesternAnimation/TheLegendOfKorra'' brings us a rather prominent member of the anti bending supremacist faction, the Equalists, who is himself a waterbender. [[spoiler: Specifically, it's the leader of the movement, Amon, who has dedicated his life to ridding the world of bending.]]
