->'''Abe Sapien:''' Behind this door -- a [[EldritchAbomination dark entity, evil, ancient, and hungry]].\\
'''Hellboy:''' Oh, well. Let me go in and [[DidYouJustPunchOutCthulhu say hi]].
-->-- ''Film/{{Hellboy}}''

So you're being attacked by TheLegionsOfHell. They're [[DemonicPossession enslaving]] your innocents, terrorizing the citizens, and generally wreaking havoc. WhoYouGonnaCall This guy.

[[TaughtByExperience Experienced]] and equipped with ImplausibleFencingPowers, ImprobableAimingSkills (probably with DepletedPhlebotinumShells), [[StuffBlowingUp demolitions expertise]], or all of the above, this character tends to be WeakButSkilled--relative to their prey, that is. They can come in several varieties, including:

* A [[TheHunter Hunter]] who hunts down and kills demons for {{revenge}} or other personal reasons.
* A [[TheChosenOne Chosen One]] who kills demons because of [[BecauseDestinySaysSo destiny]].
* A Demon or [[HalfHumanHybrid Half-Demon]] [[HunterOfHisOwnKind Hunter Of Their Own Kind]].
* A [[{{Protectorate}} protector]] of the [[WeHelpTheHelpless helpless]].
* Someone [[BountyHunter only interested in money]] who thus offers their services for a price.
* A ChurchMilitant, WarriorMonk, [[ThePaladin Paladin]], or the like on a MissionFromGod who uses a cross or holy water (among other ways to SmiteEvil) to exorcise their enemy.
* A descendant/member of [[BadassFamily The]] [[TheClan Clan]] dedicated to fighting them.
* Someone whose job description doesn't include Demon Slaying, but finds themselves [[RightManInTheWrongPlace having to step up]] and kick demon ass anyway.

They're frequently also an OccultDetective or some kind of [[HiredGuns mercenary]]. Whether they [[{{Masquerade}} hide the existence]] of {{Hell}} or slay demons openly usually depends on the setting and specific [[OurDemonsAreDifferent variety of demons]]. Also keep in mind that HeWhoFightsMonsters...

!!Examples:

[[foldercontrol]]

[[folder:Anime and Manga]]
* Sango from ''Manga/{{Inuyasha}}'', and her entire village, for that matter. They fit into the demonic protector and mercenary type.
** Itinerant monks like Miroku and shrine maidens and priestesses like Kikyo and Kaede also perform a good number of exorcisms, which may range from waving ofuda at an incorporeal spirit to beating monsters with a ceremonial staff.
* Guts in ''Manga/{{Berserk}}''. As the Black Swordsman, his role fits squarely into TheHunter, thanks to him being madder than hell about the events of the Eclipse, and the [[MoralEventHorizon actions]] [[FaceHeelTurn of]] [[DarkMessiah Griffith]] in particular. Eventually, he stops actively seeking out [[OurDemonsAreDifferent Apostles]] to kill in order to focus on healing Casca's insanity, but still runs into them, largely because of [[MagneticPlotDevice the Brands of Sacrifice]] borne by both of them.
* The Demon Hunter Organization, the [[TheClan Nanaya clan]], and (to a degree) TheChurch in the ''{{Nasuverse}}''.
* ''Anime/DevilHunterYohko''. [[RoleCalled Make three guesses on what it's about]].
* The Shinmeiryu in the [[KenAkamatsu Akamatsu]][[TheVerse verse]] (used by [[MahouSenseiNegima Setsuna]] and [[LoveHina Motoko]]) is a demon-slaying sword style. Within the ''Negima'' series is also Mana Tatsumiya, who fits into both the mercenary ''and'' priestess type (yep - a price on spirituality). Setsuna's job as a demon slayer is rather ironic, though, [[spoiler: considering she's [[HalfHumanHybrid half crow]] [[{{Youkai}} demon]] [[HunterOfHisOwnKind herself]]. Mana is also [[HalfHumanHybrid half demon]], making her a [[NinjaPirateZombieRobot half-demon mercenary priestess]]]].
* Manga/FairyTail: After the [[TheDragonSlayer Dragon Slayers ]] and the God Slayers, we learn of a new type, Devil Slayers. They function pretty much the same. [[spoiler: Ironically enough, the first and only known user of this type of Magic so far happens to be a [[HunterOfHisOwnKind Demon himself]].]]
* ''{{Kekkaishi}}''. It's really their entire ''raison d'Ítre''.
* The titular characters in ''Manga/{{Claymore}}'' are an entire organization that exists purely to hunt down and destroy demons preying on humanity, provided the side that's being preyed on requests their aid and pays an adequate fee afterwards. [[AFateWorseThanDeath If they don't...]]
** It's only made worse that [[spoiler: the central organization of the Claymores are the ones creating the demons as ''an experimental weapon''.]]
** The Claymores are actually part of a centuries long project to create the ultimate [[spoiler:[[TheDragonSlayer dragon slayers]].]]
* ''Manga/YuYuHakusho'': The job of the [[TheHunter Spirit Detective]]
* ''Manga/DororonEnmaKun''. Technically, Enma isn't supposed to slay the demons he fights (only capture them), but he doesn't care.
* TetragrammatonLabyrinth has [[ChurchMilitant the Organisation]], which was created several hundred years ago [[spoiler: by one of the main characters]] to fight demons.
* ''[[Manga/BlueExorcist Ao no Exorcist]]'' is basically this, only with exorcists. Most of them fall under a job or family business, with a few for personal reasons. [[AntiAntiChrist Rin]] falls under [[SurvivorGuilt personal]] reasons and HunterOfHisOwnKind due to his HalfHumanHybrid status. He's not the only one there, as it's mentioned that there are ''other'' half-demons out there who work as exorcists.
** Judging by what we know from Rin, the half-demons serving as Exorcists or otherwise getting involved in the war against demons isn't far-fetched; they naturally can see demons, due to their bloodline, while others have to have a masho (spirit wound) inflicted to see them.
* The [[spoiler: new magical girl system]] in ''Anime/PuellaMagiMadokaMagica'' changes into this.
* DGrayMan's baddies are called akuma, which normally gets translated into "demons". So yep, DGrayMan is pretty much this.
[[/folder]]

[[folder:Comicbooks]]
* ''ComicBook/{{Hellboy}}'', naturally.
* Devil-Slayer from ''MarvelComics''.
* John Constantine of ''{{Hellblazer}}'' from the DC. Not only does he slay demons, but he [[DidYouJustScamCthulhu cons]] them classically.
* ComicBook/{{Spawn}} always ends up fighting them sooner or later.
[[/folder]]

[[folder:Fan Fiction]]
* The raison d'etre behind the existence of NGOSuperpower [=WIC=] in ''FanFic/TheReturn''. Though they use the term "Pattern D."
[[/folder]]

[[folder:Film]]
* In the film ''Film/{{Constantine}}'', based ''ever-so-lightly'' on the ''ComicBook/{{Hellblazer}}'' comics, the titular character hunts down demonic "halfbreeds" who violate the Balance and sends them back to Hell. In the comic, he's more of a street magician who basically fights anyone who pisses him off or helps people who come to him (if he doesn't laugh them away). See TrenchcoatBrigade.
* While the ''Film/{{Ghostbusters}}'' don't target demons ''specifically'', preferring "Ghost"-busting and all, they're more than happy to zap-n-trap any demon who makes trouble in NYC.
* Ash Williams of the ''Franchise/EvilDead'' universe has the unenviable task of battling demon-possessed undead and not a few demons as well, being that ''he'' was the one who accidentally unleashed them upon the world through mishandling of a certain ArtifactOfDoom.
[[/folder]]

[[folder:Gamebooks]]
* The FightingFantasy book ''Dead of Night'' was this trope IN SPADES. The main character was a Demon-Slayer, a WarriorMonk specifically trained to hunt down and destroy the demons of the setting. During the course of the book, he averts a demonic invasion of Gallantria engineered by the Demon Prince Myurr. Virtually every opponent in the book is either a demon or someone working for them. The overall tone of the book was very dark.
** This was a recurring trope throughout the series in general, as the reader would be pitted against everything from Fire Demons to Mirror Demons to Hell Demons to Ice Demons at different times.
[[/folder]]

[[folder:Literature]]
* SolomonKane in the Creator/RobertEHoward book series. If he counts, then so do King Kull of Atlantis and Conan of Cimmeria. None of them slay demons as their day job, but have been forced to the task by the circumstances more than once in their careers.
** Solomon Kane fights evil in general and is happy to kill bandits and pirates. It's just that he keeps running into supernatural monsters. Conan kills whoever has the most loot.
* Creator/ColtRegan's first book is titled ''Demon Hunter'' for a reason
* Many, many government-employed wych-hunters (despite the name, they hunt gribblies (wych-kin), not witches) in ''Literature/TheHauntingOfAlaizabelCray'', and for most of the reasons above. The protagonist, Thaniel Fox, is also following in his father's footsteps: "the only reason [his mentor and friend] Cathaline Bennet needed was that she was odd."
* The title character of ''Literature/{{Magnus}}'' is a demon slayer. His FlyingBrick powers along with immortality makes any demon fighting him suicidal.
* The ''Literature/SpecialCircumstances'' unit is occasionally called upon for doing this, as part of their job to battle supernatural villains.
* The Shadowhunters' whole schtick in ''Literature/TheMortalInstruments'' and ''Literature/InfernalDevices''.
* In books by Raymond .E Feist, most temples are said to have a 'material' segment of the order, who mostly deal in fighting demons, along with whatever that particular God finds offensive. They tend to be able to hurt demons with mundane weapons, despite others not being able to, and many have traditional demon-banishment spells.
[[/folder]]

[[folder:Live-Action TV]]
* ''Series/{{Supernatural}}''. Much of the show's mythology revolves around them.
* ''Series/BuffyTheVampireSlayer'' is usually, well, a vampire slayer. [[OurVampiresAreDifferent Vampires in her world are demon possessed corpses]]. But she's also been fighting other demons since the very first season.
* ''Series/{{Angel}}'' was mostly this as well, although he befriended some of the less evil demons. He also slays other vampires.
* ''{{Demons}}''
* Pretty much the job description of a Makai Knight in the ''{{Garo}}'' universe.
* The girls from ''Series/{{Charmed}}'' do a lot of demonslaying during the course of the series.
* ''Series/PoltergeistTheLegacy''
[[/folder]]

[[folder:Music]]
* Voltaire's [[http://www.youtube.com/watch?v=8fDlJsYr0sY "Goodnight, Demon Slayer."]]
[[/folder]]

[[folder:Tabletop Games]]
* The Inquisition of ''TabletopGame/{{Warhammer 40000}}'' has the Ordo Malleus, an entire branch of investigators dedicated to finding and rooting out daemonic influences. Most of their agents are a mixture of StateSec and [[KnightTemplar holy warrior]], but they can also call upon a specialist [[SuperSoldier Space Marine]] chapter for aid: the Grey Knights. ''These'' guys are considered badasses even by other Space Marines, armed and armored with consecrated wargear and protected by formidable psychic powers that make them extremely good at what they do. Even the less experienced ones kick serious ass. The more veteran ones tend to turn up wearing suits of armour that can endure being stomped by a HumongousMecha, fitted with equipment like flamethrowers that burn souls.
* Demons and devils are among the most powerful enemies that ''DungeonsAndDragons'' PlayerCharacters can face, and high-level adventures will often have [=PCs=] heading ToHellAndBack, usually to destroy a particularly powerful demon lord such as Orcus.
** The Knight of the Chalice is a Prestige Class that is dedicated to fighting demons and devils. Many characters who take this class are some combination of ranger and either cleric or paladin.
** The Church of the Silver Flame in ''{{Eberron}}'' have their entire ''religion'' built around this. When they are not a CorruptChurch or [[KnightTemplar Knight Templars]], they do this, and they do it fairly well, having developed a few unique tricks like Silver Flame Exorcists and Silver Pyromancers. Aside from evil outsiders, they also hunt undead and lycanthropes (and not all of the latter are really evil, which has earned them a bit of a bad rep among them and their Shifter cousins).
*** The Druidic Sect of the Gatekeepers have been doing it for longer (not saying much, as the Silver Flame as an independent religion isn't very old), focusing more on {{Eldritch Abomination}}s from Xoriat than actual demons, however.
*** The members of The Chamber are also prone to this. However, it's worth noting that the Chamber is an organization composed entirely of ''dragons''.
*** The Giants of Xen'drik also, presumably, had something similar to tackle Quori possession, but since their solution to the Quori problem all but annihilated their own civilization, no one's entirely sure anymore.
** In TableTopGame/{{Pathfinder}}, there are several classes that can be tooled specifically for this, such as Rangers, Inquisitors, and Paladins. Of course, any character class can have DemonSlaying as a job as far as roleplay is concerned, but these three classes are highly conducive to the job as far as class mechanics are concerned.
* This is, in theory, what the Wyld Hunt in ''TabletopGame/{{Exalted}}'' is all about. Of course, the dogma of the Immaculate Faith being [[PathOfInspiration what it is]], their definition of 'demon' includes most typical player characters...
* Dwarf Daemon Slayers in ''TabletopGame/{{Warhammer}}''. In a twist, Daemon Slayers aren't in it for any greater or more noble purposes beyond the purely personal: if you are a daemon slayer, that means you've already [[DeathSeeker tried to meet your end in glorious battle against trolls and giants]]...[[SpringtimeForHitler And]] ''[[SpringtimeForHitler failed]]''. Daemons and Dragons are pretty much all that's left to challenge you, and dragons in the Warhammer setting are rare.
* The Demon Hunter template from the third edition of ''BigEyesSmallMouth'' is dedicated to fighting demons, many of which come from the hell dimension of Bazaroth.
[[/folder]]

[[folder:Videogames]]
* Dante of ''VideoGame/DevilMayCry'', who [[Pantheon/{{Combat}} is the god of this trope]], even before we listed it. He mostly fits into the mercenary type. As a [[HalfHumanHybrid half-demon]], he also happens to be a HunterOfHisOwnKind.
** Nero as well in the fourth game.
* Dante of ''VideoGame/DantesInferno'' is also a DemonSlayer, though this Dante is more of a crusader/paladin with holy power and a scythe taken from Death himself. He's in this to rescue his beloved from Hell.
* Enoch of ''VideoGame/ElShaddaiAscensionOfTheMetatron'', a human who wields the weapons of God to punish and purify the Watchers, a group of angels bent on corrupting mankind.
* Demon Hunters in the ''VideoGame/{{Warcraft}}''-verse. They follow the path of the (in)famous Illidan Stormrage, using the demons' own Fel powers against them. Also, [[WarriorMonk Paladins]], who have Light-granted abilities that specifically deal damage, or deal extra damage, to demons and undead.
* Both the [[TabletopGame/OldWorldOfDarkness Old]] and [[TabletopGame/NewWorldOfDarkness New]] versions of Worlds of Darkness have Hunters (detailed in ''[[TabletopGame/HunterTheReckoning The Reckoning]]'' and ''[[TabletopGame/HunterTheVigil The Vigil]]'' respectively), humans with supernatural abilities to fight the [=PCs=] from the other games.
* [[Franchise/SuperMarioBros Mario]], amid all the many other myriad things he has done over his career, took care of a demon in ''VideoGame/PaperMarioTheThousandYearDoor''. [[spoiler:It was the Shadow Queen, the BigBad.]]
* Most non-Persona Franchise/ShinMegamiTensei games have the main characters act as this, [[{{Mon}} while allying with a handful of 6-12]]. Though [[SummonMagic only]] [[RaidouKuzunohaVsTheSoullessArmy one]] [[RaidouKuzunohaVsKingAbaddon group]] actually does so for a living.
** Atlus has registered a "Devil Hunter" trademark. One can only assume [[ExactlyWhatItSaysOnTheTin it will involve this trope]].
* [[{{Badass}} Adell's]] title in ''VideoGame/{{Disgaea 2|CursedMemories}}'' game is Demon Hunter. Before Disgaea, this was the mission of the Church of the Maiden of Light in ''LaPucelle.''
* Amaterasu of ''VideoGame/{{Okami}}'' spends her time roaming the ancient land of Nippon and hunting down demons strewn across the land.
* Inverted in ''VideoGame/{{Bayonetta}}'' where the title character kills angels instead of demons. Is it ironic that her game, ''VideoGame/{{Okami}}'', and the first ''VideoGame/DevilMayCry'' were all made by the same guy, Hideki Kamiya? He deserves his own page for the amount of tropes that he and Clover Studios (and Platinum Games) use, this one included.
* The protagonist of the ''VideoGame/{{Doom}}'' games, affectionately nicknamed Doomguy. As a SpaceMarine, killing demons isn't exactly in this guy's job description, but when the monsters from hell go on the loose, it's up to him to blast them right back where they came from with a heaping helping of serious firepower.
* The ''VideoGame/{{Diablo}}'' series is ALL about demon slaying.
** ''VideoGame/DiabloIII'' has the [[ExactlyWhatItSaysOnTheTin Demon Hunter class]]. They are composed of people who have survived devastating demon attacks and dedicated their lives to eradicating them wherever they are found.
* The Onikiri from GirlsLove VisualNovel ''AkaiIto'' and its sort-of sequel ''AoiShiro''. But then, their definition of "demons" [[WhatMeasureIsANonHuman is very loose...]]
* Garcia Hotspur of ''ShadowsOfTheDamned'' is a professional Demon Hunter on a quest to save his girlfriend Paula from Fleming, Lord of Demons.
* Many of the Heroes in the ''DragonQuest'' series have slain countless demons (BigBad, {{Mook}}s, and everything in between) in the numerous installments. In fact, most DragonQuest games are more about fighting ''Demons'' than Dragons.
* While templars in ''VideoGame/DragonAgeII'' function mostly as [[MageKiller Mage Killers]], they also have bonuses to damage while fighting demons, likely because [[BloodMagic blood mages]] will often have demons in their service.
* In ''DemonsSouls'', the player character becomes a demon slayer out of necessity since demon souls are the only currency accepted in the Nexus.
* Played with in ''VideoGame/AsurasWrath''. The Gohma heavily resemble Demons and might as well be them for setting and story purposes, and the job of the protagonist and the other Demigods is to fight them. [[spoiler:They're not actually Demons or anything like it at all]].
* This is the job of the Vigil of Stendarr in ''VideoGame/TheElderScrollsVSkyrim'', formed after the events of the previous game.
* In ''VideoGame/TheElderScrollsIVOblivion'', your job as the Player Character is to close the [[{{Hellgate}} Gates of Oblivion]] by stepping through, killing your way through lots of Daedra, and grabbing the Sigil Stones used to power the gates.

[[folder:Webcomics]]
* Torg during the "That Which Redeems" StoryArc from ''Webcomic/SluggyFreelance''. He tries organizing a larger LaResistance of demon fighters, but since the only people he has to work with come from the [[ActualPacifist Dimension of Lame]] ...
* Main characters from {{Shadowgirls}}, especially [[spoiler: Shadowchild - they don't call her Slayer of the Elder Gods without a reason]]. However, only if we count beings from the CthulhuMythos and its [[EldritchAbomination Eldritch Abominations]] as demons.
* WebComic/DemonHunterKain - It's in the name.
* Freija and Rachel have a bone to pick with any demons they come across in ''Webcomic/TheSenkari''
* ''Webcomic/TheFoxSister'': Yun Hee describes being a Mudang as: "This is what I do. I kill demons."

* Jefferson Twilight from the ''[[WesternAnimation/TheVentureBrothers Venture Brothers]]''. When not running around with the Order of the Triad, he hunts Blaculas to avenge his mother. And no, he doesn't call them African American Vampires. Sometimes he hunts British Vampires. He doesn't know the P.C. term for Blacula.
* Hoss Delgado of ''WesternAnimation/TheGrimAdventuresOfBillyAndMandy'' is an equally opportunity monster fighter.
