"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."This is where you have Group X which is Always Chaotic Evil. Then there's Character Y, who somehow has the powers of Group X but has a conscience, often because he or she is a Phlebotinum Rebel or a Half-Human Hybrid of Warring Natures. So, Character Y becomes a Hunter of Monsters, allowing him to use his powers for a good cause. Sometimes, this turns out badly for the Hunter when it is revealed that his targets actually aren't totally evil, and a case of Van Helsing Hate Crimes can result. For some reason, vampires seem particularly prone to doing this. You will see Dhampyrs, Friendly Neighborhood Vampires, and especially Vampire Detectives engaging in it. Maybe it's because they like to turn their enemies out of spite. See Also: Boomerang Bigot, My Species Doth Protest Too Much, and Stages of Monster Grief. Someone who actually succeeds in killing off their entire people or clan has committed Genocide from the Inside. Predator Turned Protector may lead to them protecting their supposed "prey" from their own kind, who feeds on the same prey. Contrast Monsters Anonymous. Compare Pro-Human Transhuman.

Anime & Manga
- Attack on Titan
- The Rogue Titan attacks other Titans while ignoring the nearby humans. This is because it's actually Eren, on a Roaring Rampage of Revenge after his Voluntary Shape Shifting 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.
- Ymir also becomes this when her unarmed squad is cornered in a castle tower by a horde of Titans. Word of God confirms her decision to reveal herself and fight is because she's in love with Krista. She gets overwhelmed, but luckily the Survey Corps arrives in time to save her.
- Saya from Blood: The Last Vampire, Blood+, and possibly Blood-C note .
- Rin from Blue Exorcist. Mephisto even lampshades this in a recent chapter.
- The Shikabane Hime of Corpse Princess are undead girls who hunt and kill other undead.
- Dark from D.N.Angel was described as such by Argentine. Weirdly, he's technically an artwork that steals other non-living evil artwork. Krad counts as well; his mission in life is to kill Dark. Krad's not only another living artwork, but the same exact one as Dark, making him not only a hunter of his own kind, but a hunter of himself, which is probably as far as you can take this trope.
- Nagasawa from Dawn Tsumetai Te is immune to the worst effects of Nightshift, whose not-so-fortunate victims he must hunt down and kill using the very mutations that the Nightshift has given him.
- Fullmetal Alchemist
- Scar only targets alchemists, despite using alchemy himself. Of course, Scar never identifies himself as an alchemist because his religion considers it a sin, thus he exploits a Loophole Abuse because true alchemy is three stages (Composition, Deconstruction, and Reconstruction), and he only stops at the second, which is still enough to blow a person's body apart. He gradually overcomes this.
- Greed spends quite some time fighting other homunculi after his Heel–Face Turn.
- Alucard is an interesting case; he's frequently as bad or worse than the vampires he's hunting (maybe...) and takes far too much glee in killing them, often getting 'creative' in his methods. Really, he only hunts vampires because he's bound to follow orders from the head of the Helsing family, and they're in the vampire hunting business.
- Alucard's fledgling, Seras Victoria, was a police officer before joining the Helsing organization so little has changed for her. It's just that now the criminals she hunts are a lot more dangerous.
- Mahou Sensei Negima!:
- Setsuna is a half-demon who hunts demons. They asked for it, however, by kicking her out for her albinism.
- Similarly, Mana Tatsumiya is also a half-demon who specializes in exorcisms.
- Mobile Suit Gundam 00 has a Sci-Fi twist on this with Setsuna's Gundam Exia: its primary purpose is to hunt down any Gundam should its pilot go rogue, since its GN sword is the only weapon that can penetrate a Gundam's GN field. Though late in the first season, the Earth's military gets their hands on GN Drive technology, meaning Exia has a wealth of targets from then on.
- Neon Genesis Evangelion
- Rei Ayanami is an artificially created Angel/Human hybrid who pilots an Evangelion to fight Angels.
- The EVAs themselves are reverse engineered from the first two Angels.
- Ninja Slayer is about a super-powered ninja who slays other super-powered ninjas. He's not the only example in-series, however: Dragon Yukano, Yamoto Koki, and from the villains' side, Darkninja, could all be considered hunters of their own kind.
- The main character in Kei Kusunoki's Ogre Slayer.
- A non-species example: The Seven Warlords of the Sea in One Piece are government sponsored pirates who given amnesty (and often a blind eye to their other shady dealings) in exchange for bringing down other pirates.
- Averted in Saiyuki. On a few occasions Sanzo's three sidekicks get accused by the random demons they fight of being an example of this trope, as they're following a human who has a reputation of being a demon-slayer. However, the only reason the group ends up fighting those demons is because said demons have little idea of the trio's backgroundsnote and are stupid enough to get in their way in the first place.
- Natsuno aids in the efforts to stop the vampires infesting Sotoba Village in Shiki, ultimately killing The Dragon and himself in the process.
- In Super Dimension Fortress Macross/Robotech, Milia, a Zentraedi (or is that Meltran?) who is obsessed with defeating the human ace Max. When she is captured by Max, not only does she do a Face–Heel Turn, she becomes his partner fighting the Zentraedi, but tends to shoot down her opponents with nonlethal shots when possible.
- In subsequent Macross shows, "cultured" Zentraedi are more than willing to do their part to defend their human allies from their "uncultured" brethren.
- In Tokyo Ghoul:re, the protagonists are part of a newly-formed team of artificial One-Eyed Ghouls that CCG has created to hunt Ghouls. They clearly think of themselves as still being human, but wield the same abilities as an ordinary Ghoul and are viewed with mistrust by their peers.
- The mistrust is a bit justified as one-eyed ghouls can't digest human food, so they have to feed off humans and ghouls.
- The heads of CCG the Washuu Clan are an old family of Ghouls who hunt other Ghouls.
- Trinity Blood: Abel Nightroad 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 of the three who actually makes it a point to hunt vampires. His sister isn't shown to hunt anyone (in fact, she's the empress of the vampires), and Cain doesn't care who he hunts/hurts.
- UQ Holder!:
- Kuromaru is a demihuman of some kind trained in demon-hunting (by the same school that trained Setsuna, no less).
- The eponymous organization itself, made up primarily of immortals and intending to provide supernatural denizens (immortals in particular) with a home, will occasionally have to go hunt down an immortal causing problems in society. Either they recruit these errant immortals into the organization... or they neutralize them.
- Vampire Hunter D goes after the vampire Nobility who once ruled the earth.
- Both Robin and Amon in Witch Hunter Robin are witches who hunt other witches.
- Wolf's Rain:
- Darcia is a villainous example, hunting the wolves despite being part wolf via a traitorous bloodline.
- Blue Yaiden is one unwittingly.
- In the original Yu-Gi-Oh! manga, Yugi's snobby classmate Kujirada had a "hidden character" virtual pet (as in, it would live two months, as opposed to normal ones, that lived twenty-one days). Unfortunately for him, it was harder to take care of, and had a malignant intelligence, along with the ability to control Kujirada. The evil virtual pet eventually got tired of normal virtual food, and directed its owner to link it to other kids' devices so it could devour other virtual pets. It met its end when it tried to prey on Yugi's pet, who due to swapping data with Jonouchi's pet, was much tougher than it looked.
- YuYu Hakusho:
- Yusuke 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.
- Both Merry and Engi from Yumekui Merry 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.
- Hellboy, as demonstrated in the page quote.
- Andrew Bennett, from DC Comics' I, Vampire series in House of Mystery, was a vampire determined to hunt down the line of evil vampires which 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.
- If you want a not-so-sunny example of this trope, look at original-model Lobo. He hunted down and killed every single member of his own race... for fun.
- The X-Men in general fight evil mutants quite often when they aren't fighting anti-mutant racists.
- X-Factor began as a team that hunted down mutants. The general public didn't know that the team members were mutants themselves and that they were actually trying to help the mutants they "hunt" down.
- 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 technically mutants. In theory, this would act as a Logic Bomb, 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 whoever thought it up had hoped.
- Eddie Brock's Venom is like this. One of the few reasons he'd willingly ally himself with Spider-Man is to fight Carnage or another Symbiote; he simply hates them. This became a far-more prominent goal when he later becomes 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.
- The French comic Raptors features Drago and Camilla, a Brother–Sister Team duo of vampires who systematically hunt down all other members of their kind. The feud started when the majority of vampires chose to give up most of their powers and bestial instincts so they could walk around in the daylight and rule humanity openly. Drago and Camilla's father was opposed to this and murdered (along with his wife) for his defiance, leading his children to swear revenge after they were safely whisked away.
- Vampirella: Depending on the Writer, Vee is typically portrayed as a vampiress who manages her own Horror Hunger by feeding either on Asshole Victims or blood bags stored in a fridge. She has taken down many fellow vampires in her quest to rid the world of evil, with Dracula himself being her Arch-Enemy.
- Many a Mary-Sue Hunter 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 Sues themselves. If you think about it, having a character beat an over-idealized character such as a Mary Sue (with the exception of Anti Sues) 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) and then succeed.

Films — Live-Action
- Kaiju seem to hate each other with a passion, needing little reason to fight each other whenever their paths cross, only considering a truce when worse Kaiju like King Ghidorah show up.
- According to one version of Blade Runner, 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 "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.
- Hellboy: The title character 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. Notably, he attempts to negotiate with the demon Sammael before resorting to violence.
- Hellboy II: 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.
- In The Last Witch Hunter, there are witches working for Church Militant Axe and Cross.
- Glaeser is implied to be one; while part of Axe and Cross' court, she uses magic and divination to aid them.
- Chloe becomes one by the end of the movie. She's rather nonchalant and lampshades it:
Chloe: Why can't a witch be a witch hunter?
- Although not directly called forward, as a dwarf, Bolivar Trask in X-Men: Days of Future Past is a human mutant who hunts down super-powered human mutants in order to advance technology through gruesome experiments.
- In The Stinger of Doctor Strange, Mordo is shown to have started hunting down sorcerers on account of there being too many sorcerers in the world.
- The Legend of Drizzt:
- Drizzt Do'Urden from the Forgotten Realms 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 the Forgotten Realms 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. As one Hive Mind after another ravaged the world, seeking only to 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, until at last it became no different than them.
- The eponymous Night Huntress, at least at first.
- Night Watch. 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 "Call" they use to attract victims. It is only audible 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.
- White Fang loathes other dogs to the point of going out of his way to assassinate them when he spots one alone.
- In The Falconer, Aileana's mentor for faery hunting is Kiaran, who is himself a faery. He doesn't talk about his motives much, but there are hints that some event in his past caused him to change sides.
- Lord Voldemort from Harry Potter could be considered this, given that he seeks to eliminate Muggles and Muggle-born wizards despite being half-Muggle himself. The same goes for Dolores Umbridge, who viciously persecutes Muggle-borns even though she's half-Muggle like Voldemort.
- In Eden Green, the title character is infected with an alien needle symbiote that renders her immortal. She immediately makes it her mission to destroy herself and all other infected humans.
- Journey to Chaos: Eric has become a monster that hunts other monsters. He still thinks of himself as human and even after accepting that he really is a grendel he is still sympathetic to humans so he thinks nothing of killing them. Kallen would insist that he does not fit this trope because he is not a monster but a demon.
- In Void City, Evelyn is a Friendly Neighborhood Vampire who works for an organization of vampire hunters, subsisting solely on animal blood and destroying her monstrous kin to protect innocent humans. Greta is also a vampire who regularly hunts and destroys other vampires; but in her case, it's because she just really likes killing things and enjoys the challenge offered by semi-immortal prey which requires extremely elaborate measures to destroy.
- In The Witchlands, the Hell-Bards are unregistered witches who've been caught and pressed into service of hunting down other unregistered witches.
- Athena from the 2000s Battlestar Galactica is a Cylon who fights against other Cylons. And then there's Tigh, Tyrol, and Anders who were fighting against the Cylons for years, unaware of their true nature.
- Buffy the Vampire Slayer:
- The title character of Angel is a vampire who hunts other vampires. When Angel first meets Buffy 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 also fits this description, although he initially inverts some parts of the trope since he starts out fighting vampires and demons not because he wants to be good, but because he can no longer attack humans and REALLY misses 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 Kamen Rider:
- Almost all of the Kamen Riders from the Showa Era (1971-1989) of the franchise are this, as they were cyborg mutants created by the villainous organization, but escaped before the brainwashing could be completed or defected afterwards. Because the Monsters Of The Week are also cyborg mutants, the result is this trope.
- In Kamen Rider Faiz, Faiz/Takumi is actually the Wolf Orphenoch.
- In Kamen Rider Kabuto, Tsurugi/Sasword is actually the Scorpio Worm. Scorpio Worm then killed the real Tsurugi and take his identity as a result. Unfortunately for Scorpio Worm, Tsurugi's will successfully fights back against Scorpio, and Scorpio proceeds to completely forgot his Worm persona as a result.
- In Kamen Rider Kiva, Wataru is part Fangire, making him sort of a Dhampyr.
- In Kamen Rider OOO, Eiji does not start this way, but he slowly becomes a Greeed near the climax of the series.
- In Kamen Rider Wizard, 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.
- Multiple in Kamen Rider Amazons, There's Haruka Mizusawa (Amazon Omega), a half-human & Amazon hybrid, Jin Takayama (Amazon Alpha), a human injected with the Amazon cells, and Mamoru (Mole Amazon) a child-like Amazon that works with the protagonists. Season 2 has Chihiro (Amazon Neo), seemingly a human but with Amazon characteristics, and Iyu (Crow Amazon), a human girl killed by her Amazon father and brought back as an Amazon.
- Ruby on Supernatural is a demon who fights other demons and helps Sam fight them. Sam is arguably another example of this trope, because his Psychic Powers are caused by having been fed demon blood. Of course, it turns out Ruby is among the worst of the lot and was driving Sam to his destiny to release Lucifer from his prison. Which he did.
- In Terminator: The Sarah Connor Chronicles, 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.
- Helena from Orphan Black has been indoctrinated to believe that clones are unnatural abominations to be destroyed...but the cult that raised her conveniently neglected to mention that she's a clone herself.
- After extended psychic contact with the Doctor, Rusty the Dalek from Doctor Who becomes this.
- "Princes of the Dreams" by Doug the Eagle ("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.
- Martin DeVries of Shadowrun deliberately became a vampire in order to hunt them on their own terms.
- Dungeons & Dragons
- One of the potential racial backgrounds for the Shardmind in 4th Edition is Shard Slayer, a Shardmind which believes that, since their kind was born from shards of the living gate, then a dead Shardmind's lifeforce 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. In 3.0, only an evil Ranger can choose their own species, however, in which case they qualify for this trope. In 3.5, the evil limitation is removed; note though that "Favored Enemy" involves some non-combat bonuses, so a ranger could simply pick his own species to ease up interaction, or because they're likely the most common enemies (in the case of humans) rather than any desire to hunt them down.
- 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 too 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 the New World of Darkness:
- Vampire: The Requiem 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.
- Mage: The Awakening has Banishers, mages whose Awakenings went 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.
- Hunter: The Vigil 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.
- Second edition Werewolf: The Forsaken has the Blood Talons, whose favored prey in the sacred hunt is other werewolves, those who've gone to the bad one way or the other.
- In the Old World of Darkness:
- Vampire: The Masquerade has the Baali, a bloodline known for their long association with demons and eldritch abominations. One faction of the bloodline worships these entities for power; the other hunts down infernalists, including their own kin, with extreme prejudice, to prevent them from breaking the world.
- Mage: The Ascension has the Technocracy, one of whose precepts is the destruction of Reality Deviants - most prominent among whom are non-Technocratic mages.
- Alucard from Castlevania definitely counts, being heavily inspired by D.
- Rayne from BloodRayne is a Dhampyr with one hell of a vendetta against her vampiric father Kagan for the circumstances leading to her birth.
- Full-blooded demon Sparda in the Devil May Cry 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. Nero in DMC4 counts as well, if one accepts the cut material where he is Vergil's son — Dante's nephew — and thus making him a quarter-demon.
- In Sid Meier's Pirates!, you have the option of only going after other pirates if you so choose.
- The main character in the game Divinity II: Ego Draconis 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 until the slayer commander and their slayer buddies attack the main character.
- Ashrah of the Mortal Kombat 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.
- Mega Man X:
- The biggest reveal is that Zero is the original Viral Maverick (meaning that The Virus originally came from him). Not only is this fitting for the trope, it also makes him the hunter of the race he unwittingly created.
- X himself qualifies, since all Reploids (Repliroids, based on X's designs) and, by extension, Mavericks/Irregulars stem from him.
- Kharg from Arc the Lad: Twilight of the Spirits says that he is going to do this when he finds out that he is a Half-Human Hybrid, but he decides not to later.
- Balthazar from Baldur's Gate II: Throne of Bhaal. He knows the Bhaalspawn aren't Always Chaotic Evil, 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 [PROTOTYPE] killing the viral monsters controlled by Elizabeth Greene, including Greene herself. Alex qualifies because he is the virus.
- If he befriends or becomes the lover of The Warden in the original Dragon Age: Origins, Zevran Arainai becomes one of these in Dragon Age II. 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 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 drinking Darkspawn blood and taking the Taint into themselves, turning them into a type of high-functioning ghoul with their humanity intact. This also allows Wardens to permanently kill the Archdemon by forcing its soul to Body Surf into them at the moment of death, destroying them both.
- A Mage Hawke in Dragon Age II frequently finds themselves hunting down Blood-Mages, berating them for their Well-Intentioned Extremist 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 Apostates and Maleficarum.
- Played straight if a Mage Hawke ends up being Templar-Aligned at the end of the game. If still alive, Carver will call them out on this and points out that if 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 not happy about it and only agrees because innocent people are being killed in the crossfire.
- In Origins, the guild called The Mages' Collective can be this. While their primary goal is to support mages, Circle or Apostate alike, they maintain a hard distinction between Apostates and Maleficarum, and you can take on missions from them requiring you to kill blood mages or cultist groups. As well as this, they are aware that they sometimes require the templars to turn a blind eye to what they do, and you can accept a mission from them that will allow you to "reward" a templar with lyrium potions.
- Demon hunters 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 Last of His Kind, though observant players have noticed there is at least one other black dragon (Sabellian) unaccounted for. And it turns out there was one other uncorrupted black dragon as well long before he came around named Ebyssian, who hid himself as a spiritwalker among the tauren named Spiritwalker Ebonhorn.
- The Elder Scrolls V: Skyrim:
- The Dragonborn is a rare mortal born with the divine Aedric soul of a dragon. Because dragons are ageless and, even if they are slain, can be resurrected by another dragon, it takes another dragon or Dragonborn absorbing their soul to permanently kill them. Akatosh, the draconic God of Time, chief deity of the Imperial pantheon, and "father" of dragons, specifically created the Dragonborn to serve as a "natural predator" to the dragons. In fact, the Dragonborn's very title reflects this: in Dovahzul, the language of the dragons, "Dragonborn" is "Dovahkiin" which, when broken down the way most dragon names are, becomes "Dov Ah Kiin", or "Dragonkind Hunter Born". Naturally, dragons see the Dragonborn as their equivalent to a Humanoid Abomination.
- The Dragonborn DLC plays it straight as well, with the "Last Dragonborn" being forced into a confrontation with 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. Ironically, a Dragonborn that sides with the Volkihar vampires can also play this trope straight, since a large number of side quests involve killing lesser vampires, mostly for drawing too much mortal attention to themselves and partly because the Volkihar vampires just plain look down on the thin-bloods.
- In Dark Souls, 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 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 nothing left to lose.
- Raziel in Legacy of Kain is a three-fold example. A 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 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, as well as members of the Sarafan Order, at times.
- Subverted in League of Legends. Miss Fortune is a pirate hunter because her mother was killed by pirates, but her attire is completely pirate-like. A Pirate Girl? 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 Power Fist 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 Immortal Souls, 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?
- Dwarf Fortress has the legendary Cacame Awemedinade, The Immortal Onslaught. An elven resident of a dwarf-conquered civilization, his wife was killed and eaten by other elves. He later ended up becoming an Elven King of Dwarves, seemingly out of pure burning hatred of the pointy-eared ones.
- In the backstory of Darksiders and its 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, which they did.
- 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 Rage of Bahamut.
- Saints Row: The Third features a cheesy Show Within a Show called Nyteblade, about a vampire hunter who was turned into a vampire himself.
- In Sword of the Stars, the Liir's greatest weapon against the dreaded Suul'ka power-mad Liir Elders who enslaved the rest of the Liir so they could live forever in space is The Black another Liir Elder who lives in space like the Suul'ka.
- inFAMOUS: Second Son has the D.U.P., who are out to recruit, neutralize, or kill those suspected of being superhuman, and are led by Brooke Augustine, a Conduit who has bestowed her concrete-based powers to the rest of the group. Her actual purpose however is to imprison them in one place so they cannot be harmed by outside forces.
- Guilty Gear: The setting is home to a bunch of artificially-engineered Humanoid Abominations called Gears, and the oldest and strongest of all of them is hunting down and killing the rest out of guilt for creating them, hence the title. That would be the main protagonist, the crass bounty hunter Sol Badguy.
- In Bloodborne, the city of Yharnam is patrolled by Hunters who head out every night to cut down monsters created by the Scourge of the Beast. When Hunters are infected, Eileen the Crow and her followers, the Hunters of Hunters, put them down. There's also the Moon Presence, a Great One who created the dream world so it could guide the Hunters to kill other Great Ones. Jury's out on whether that's good or evil though.
- The Vampire Hunter Treasure Art in Dragon's Crown implies that the Vampire Hunter hired in the Church Cover-up side-quest is one. Not only does he look a lot like Alucard from Castlevania: Symphony of the Night, but the Flavor Text suspiciously mentions that the Vampire Hunter leaves before the sun rises.
- In Nocturne: Rebirth has an anti-villainous example in Idith Midowin, who hunts her fellow vampires out of revenge for turning her mother into a vampire, who then turned her into a vampire. Her mother went insane from the process and had to be mercy killed, further fueling Idith's hatred of every vampire on the planet.
- In NieR: Automata, there exists Executioner-Type YoRHa androids that exist to fight androids that have gone rogue or to kill anyone, such as Scanner-Types, that learn too much about Project YoRHa. You encounter a few around, like 7E at the start of the game, another in a side quest and 2B herself, whose actual designation is 2E.
- Arcueid took this trope to its logical conclusion, making herself the Last of Her Kind.
- Also in Tsukihime, the head of the Tohno family has the obligation to find and kill any family members who succumb to their demonic blood.
- Background material also refers to a vampire by the name of "Enhance", who has sided with the Church and works to annihilate his own kind. Apparently he is a relatively "young" vampire and rejects his monstrous nature, holding onto as much of his humanity as possible.
- Sam from Sluggy Freelance is a vampire who often fights other vampires, including "helping" take down the Lysinda Circle. Mostly because chicks think it's cool.
- Shadowchild from Shadowgirls is an Eldritch Abomination created by one of the Outer Gods with the purpose of fighting other Eldritch Abominations, and even Elder Gods.
- Girl Genius:
- Othar Tryggvassen, Gentleman Adventurer!, 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 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".
- Othar Tryggvassen, Gentleman Adventurer!, 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 meeting his doppelganger:
- 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 Were Geek, Joel attempted to turn one of the Hunters into a geek, with somewhat predictable results.
- 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 Heart Core, a demon hunter from 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.
- In Skin Horse, The Dane, greatest and most feared/revered of all Mads, proves to be out to kill all Mads on account of their being dangerous to the world. The fact he is, himself, a Mad does not bother The Dane.
- Blunt in Freefall believes that the presence of intelligent robots who are able to do everything better than humans will result in humans becoming relaxed, happy, and safe...which, in his (possibly brain-damaged) assessment, is a very bad thing. Therefore, he belives the intentional release of a last-ditch safeguard program that, essentially, would lobotomise every robot on the planet is the only solution, and when it is barely prevented he goes full-court press to prove that stopping it was a mistake. He fully intended for himself and his co-worker, Edge, to be the last two intelligent robots left, in order to ensure the process took place, at which point they would reactivate their communicators, receive the neural-pruning patch, and join their fellows. (Edge was not thrilled by this idea and just wanted to be the last robot standing, forever.)
- Show Within a Show example from Look to the West: one of the seminal works in that world's "Automaton fiction" craze of the 1820s-1850s period is The Venator, about a Killer Robot whose role is to hunt down and kill the last of his own rebellious kind and, once this is accomplished, to dismantle himself.
- SCP Foundation:
- Dr. Alto Clef is a Reality Warper (or at least is totally immune to the powers of Reality Warpers) who is committed to using his powers only to get rid of other reality warpers.
- Assuming that SCP-349 is the work of one person, that person is an immortal who hunts and kills immortals who started out mortal and purposefully became immortal.
- Feeding The Trolls is a series making fun of internet Trolls and other inflammatory figures on YouTube, essentially trolling trolls.
- Danny Phantom is a half-ghost who fights other ghosts.
- Generator Rex, Rex being an EVO, is employed to fight EVOs. This trope is actually played with because everyone on Earth, 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 Adventures of the Galaxy Rangers, Shane Gooseman was the youngest and most advanced of the Artificial Human 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 The Real Ghostbusters 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 Containment Unit was caught with Slimer's help).
- In Scooby-Doo Meets the Boo Brothers, 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.)
- The Legend of Korra brings us a rather prominent member of the anti-bending supremacist faction, the Equalists, who is himself a waterbender. Specifically, it's the leader of the movement, Amon, who has dedicated his life to ridding the world of bending. And his waterbending is the evil bloodbending variety.
- Subverted and downplayed in Adventure Time Stakes: we find out Marceline the Vampire Queen was a vampire hunter, but did most of her work before she became a vampire. In fact, she began a vampire literally seconds before the last other vampire died. The mini-series is then about her hunting those vampires who came Back from the Dead in the present, but they actually came back because she stopped being a vampire.
- With the exception of Jim or course, every Trollhunter from Trollhunters fit this description.
