->''"Go ahead. Take it. You'll be so very powerful... And what harm can it do?"''
-->-- '''FlavorText''' for [[http://gatherer.wizards.com/Pages/Card/Details.aspx?multiverseid=24601 Agent of Shauku]], ''TabletopGame/MagicTheGathering''

Not to be confused with TheCorruption, which is more of an impersonal force, this character's primary role in the story is to bring out the worst in everyone around them. Often, their ultimate goal is getting the hero to do a FaceHeelTurn.

They fulfill this role willingly and knowingly -- perhaps they are doing it ForTheEvulz, or because they seek validation by dragging others down to their level. Perhaps corrupting the hero advances their own agenda in some way -- perhaps opening the hero to [[WeCanRuleTogether recruitment as an ally]], perhaps [[HiddenAgendaVillain something more subtle]]. Or maybe they just think that HumansAreBastards and are trying to prove it.

In any case, do not expect these guys to get a whole lot of development themselves -- they are less characters in their own right than they are the [[GoodAngelBadAngel metaphorical devil on someone else's shoulder]] given physical form. If they ''do'' get much CharacterDevelopment, they will probably be a ShadowArchetype for the character they are trying to corrupt. Expect them to be very smooth and clever, though precise competence level will vary.

This character will almost always be a serious villain, though they can be parodied by being made particularly inept. If they're ''not'' the BigBad, expect them to still be an important villain with a lot of screen time -- this trope doesn't work too well if you can't interact with the characters you're corrupting.

Do not expect these guys to pull a HeelFaceTurn; they are more likely to go into a VillainousBreakdown if they are definitively rejected. If they fail, it will probably be because they [[EvilCannotComprehendGood cannot comprehend good]]. Perhaps they want to [[WeCanRuleTogether rule with the hero]], though this is by no means a universal trait, and not everyone who makes that offer is an example of this trope. May offer a DealWithTheDevil at some point, but is just as likely to use mental and emotional manipulation to force their victim's hand without any sort of formal bargain -- see HannibalLecture and BreakTheCutie for some favorite tactics.

Sometimes the Corrupter cares more about turning the hero than his own life, and invites them to StrikeMeDownWithAllOfYourHatred.

Can be of any evil alignment; a LawfulEvil who wants a new minion, a NeutralEvil who wants an apprentice to continue their work, or a ChaoticEvil who just likes screwing with people. If it turns out that it was all a SecretTestOfCharacter or otherwise necessary, see AChatWithSatan.

Closely related tropes are ManipulativeBastard and TheChessmaster. See TheVamp or LadyMacbeth if female. Will often overlap with an evil WarriorTherapist, an EvilMentor or TreacherousAdvisor. See TheCorruptible for the typical victim of this kind of villain, and IncorruptiblePurePureness for those immune to their wiles.

The [[GoodAngelBadAngel Shoulder Devil]] is a literal version of this trope, though these days is one more likely to be played for comedy.

!!Examples

[[foldercontrol]]

[[folder:Anime & Manga]]
* Johan Liebert, the eponymous ''Anime/{{Monster}}''.
* In ''Webcomic/TowerOfGod'', Grace Luslec Mircea is this to 25th Baam, to the point he adopts his name and become Jyu Viole Grace (Jyu Viole, adopted by Grace). In a way, the Tower itself, a GeniusLoci, corrupts its inhabitants with the promise of having everything you wish for at the top.
* ''Manga/{{Naruto}}''
** Tobi/[[spoiler:Obito Uchiha]], who in turn appears to have been corrupted by [[spoiler:Madara Uchiha]]
** Orochimaru when he was still alive was one of these as well.
** Danzo also acts as an indirect example given all the people who he has caused to make a FaceHeelTurn through his actions. All of these combined examples add up to a GambitPileup.
** It is implied that Zabuza had a similar effect on Haku, though Haku never saw him as anything other than a loving master. More like, they met each other halfway. Zabusa taught Haku how to be harder and more ruthless, but Zabuza also learned to care about someone other than himself.
* In [[Anime/FullmetalAlchemist the 2003 anime version]] of ''Manga/FullmetalAlchemist'', Lust's job is to be The Corrupter who tempts desperate alchemists into seeking the forbidden knowledge of how to make Philosopher's Stones. Envy also ends up creating Wrath by tempting the nascent homunculus with incomplete Philosopher's Stones.
* Pasder and the Zonderians in ''Anime/GaoGaiGar'', [[spoiler: and the Primevals later on]].
* Naraku from ''Manga/InuYasha'' frequently tries to corrupt the hearts of the heroes; sometimes this is for a practical purpose (usually corrupting the Shikon Jewel), while sometimes it's [[ForTheEvulz just for the sake of evil.]] At one point, he tries to force Kagome to choose between killing the priestess he has mind-controlled (which would allegedly both condemn the priestess to hell and corrupt Kagome's heart for killing her knowing that) or being killed by her; at another, he tries to get Sango to kill an innocent little girl in order to kill him, which is also the only way to save her love interest's life [[spoiler: ([[MagnificentBastard only Naraku wouldn't have died anyway because she was only talking to an illusion of himself]]).]]
* The Beast from ''Manga/{{Berserk}}''. The Berserkerverse's resident [[SuperPoweredEvilSide super-powered evil]] {{hellhound}} entity that [[EnemyWithin dwells within]] [[ByronicHero our main character,]] this mean puppy constantly tries to egg Guts into killing his friends - [[MurderTheHypotenuse especially Casca]], who is [[MoralityChain the only person who stops Guts from becoming a sociopathic killing machine.]] However, the Beasts wants this to happen in order to [[SplitPersonalityTakeover take over Guts' soul]], so whenever he gets the chance, whether Guts is emotionally fragile from longing for intimate affection from [[StarCrossedLovers his lost love]] or mentally vulnerable from wearing the [[AdaptiveArmor berserker armor,]] the Beasts tells Guts a range of hideous things: that he doesn't really love Casca anymore and only uses her experience as way to [[ThePowerOfHate fuel his hate for Griffith]], or that he enjoys being a heartless killing machine [[EvilFeelsGood because it gives him power]]. The Beast comes in and out of the picture, but always reminds Guts that [[WeWillMeetAgain it'll be back...]]
* Despite being the BigBad, Dakki of ''Manga/SoulHunter'' counts as this. One of her Paope gives off a sent that eventually drives men to her side and makes them devoted slaves. Mix in her own skills at manipulation with just her looks and words and you have a nasty combo to deal with. Just look at the Emperor. He starts off normal [[spoiler:and many chapters in, gets turned into a human paope weapon that is barely aware of who he originally was.]] And she's been doing this for hundreds of years as well.
* ''Manga/SoulEater'' has Asura and his Clowns as well as Medusa for Crona.
* [[VillainProtagonist Light]] [[BrokenAce Yagami]] of ''Manga/DeathNote'' plays this role for the (albeit less-than-heroic) [[MadLove Misa]], [[SmugSnake Takada]], and [[KnightTemplar Mikami]], turning each of them in turn from moderately unpleasant people with mild psychological problems to unrepentant mass murderers. Then, of course, there's his cult and the unnamed masses he screwed up ''there''...
** Light also inadvertently causes [[spoiler: his father]] to make a deal with Ryuk [[spoiler: that results in his death]], bringing the most innocent character in the series into the mess and [[spoiler: nearly making him a murderer too. Though in the end, Soichiro turns out to be too pure-hearted to ever use the Death Note, which Ryuk notes meant he was able to die free from its curse of misery and fear.]]
** Light himself was corrupted in the first episode by the {{Shinigami}} Ryuk and the [[ArtifactOfDeath Death Note]] itself, though he was definitely TheCorruptible to begin with.
* In the ''Anime/MonsterRancher'' anime, Moo has the ability to change good monsters into bad ones.
* In ''Anime/UmiMonogatari'', Sedna corrupts the islanders, sea creatures, and Urin to suit her needs.
* Played with in ''Manga/TokyoGhoul''. Although she's already dead, [[TheVamp Rize]] appears to Kaneki as a hallucination and encourages him to surrender completely to his HorrorHunger. Eventually, she walks him through his DarkAndTroubledPast to convince him to accept her -- she's merely the form he chose to represent his own anger and resentment, so he has someone else to blame. He embraces these emotions, and his Ghoul nature, by symbolically (and messily) eating her, then spends the next six months on a RoaringRampageOfRevenge.
* ''Manga/RosarioToVampire'': [[ANaziByAnyOtherName Kuyou]] seems to have served this role to the [[AbsurdlyPowerfulStudentCouncil Public Safety Commission]]. Before he took charge of the group, they were actually a good, necessary institution; it was largely under him that they deteriorated into the band of corrupt {{yakuza}}-esque thugs we all know and love to hate.
[[/folder]]

[[folder:Comic Books]]
* {{Darkseid}}, being the GodOfEvil of the DC Universe, has played this role from time to time. The one he bragged about to Eclipso? He once visited New Genesis long before he took on the mantle of Darkseid and saw a beautiful young boy, pure and innocent. With little more than words and the death of a pet bird, Darkseid twisted the youth and gave him a new name -- ''[[TortureTechnician Desaad]]''.
* In ''ComicBook/AllFallDown'', [[spoiler:Phylum]] becomes this to [[spoiler:Pronto]], thanks to a booby-trapped voice-box that gives poisonous advice.
* In ''ComicBook/{{Hellblazer}}'', Nergal attempted to corrupt a young John Constantine by disguising himself as a boy and offering him a cigarette. John took the cigarette and Nergal privately gloated that he had started the boy down a path of corruption. Then he noticed that John had managed to steal the entire pack from him when he wasn't looking. The two eventually become archenemies.
* The first Comicbook/{{Grendel}} Hunter Rose. Everyone in his life who isn't one of his victims become worse due to his influence.
[[/folder]]

[[folder:Films -- Animation]]
* Scar from ''Disney/TheLionKing''.
* The anthropomorphic fox J. Worthington Foulfellow in the Disney version of ''Disney/{{Pinocchio}}''.
** The coachman even more so.
[[/folder]]

[[folder:Films -- Live-Action]]
* Angelica claimed that Jack was this towards her in ''Film/PiratesOfTheCaribbeanOnStrangerTides''.
-->'''Jack:''' You displayed a great deal of technique for someone I supposedly corrupted.
* Many versions of the Joker have shades of this, though the one from ''Film/TheDarkKnight'' is perhaps most explicit about it.
-->'''Joker:''' [[MagnificentBastard I took Gotham's White Knight and I brought him down to our level.]]
* ''Franchise/StarWars''
** [[BigBad Emperor Palpatine]] is a classic example, particularly in ''Film/RevengeOfTheSith'' (where he is ''very'' successful) and ''Film/ReturnOfTheJedi'' (not so much...).
** Most Sith Masters in the Franchise/StarWarsExpandedUniverse are like this too, particularly when [[WeCanRuleTogether recruiting apprentices.]]
* ''Grudge Song'', the fourth of the ''[[Film/JoshuuSasori Female Prisoner Scorpion]]'' films, features a desperate attempt by the protagonist to do this to a calm, earnest Buddhist inmate in order to cause enough havoc to escape from [[spoiler:Japan's equivalent of death row]].
* In ''Film/GhostShip'', it's [[spoiler:Ferriman]]'s job to bring out the absolute worst in people, because if they commit enough sins they'll effectively damn their souls, which he can then harvest and take to Hell. He pressures a segment of the crew on the Graza into starting a complete orgy of violent murder of everyone else on board so they can get their hands on all the gold he brought with him. [[spoiler:He tries the same routine on the present day salvage crews, but it's only Epps who takes a definite stand against his material offers at the end.]]
* In ''Film/XMenFirstClass'', Sebastian Shaw is responsible more than any other figure in the X-Men Universe for Magneto's StartofDarkness.
[[/folder]]

[[folder:Literature]]
* The Un-man from ''[[Literature/TheSpaceTrilogy Perelandra]]'', which is fitting, since he's {{Satan}} possessing a human, in a sci-fi setting.
* Sang-drax from ''Literature/TheDeathGateCycle'', who is evil incarnate (or rather, a piece of it) and feeds off of hatred, fear, and suffering -- convincing mortals to do evil is his equivalent of popping a frozen dinner into a microwave.
* Calesta from the ''Literature/ColdfireTrilogy''.
* Franchise/TolkiensLegendarium
** [[{{Satan}} Melkor]] is this. He corrupted several elves and other creatures to become hideous forms of the former selves.
** Sauron -- not so much in ''Literature/TheLordOfTheRings'', but definitely in the Downfall of Númenor chapter in ''Literature/TheSilmarillion'' -- stripped of all other resources, his last resort is to corrupt the entire Númenórean Empire and then sit back and watch their civilization spectacularly implode (unfortunately on top of him). He also corrupted the nine mortal kings who would later become the Nazgûl.
** Gríma Wormtongue corrupted King Théoden. Who was in turn corrupted by Saruman who was corrupted (somewhat indirectly) by Sauron who was corrupted by Melkor. Suffice it to say, Tolkien was fond of this trope.
* Explored in detail in ''Literature/TheScrewtapeLetters'' by Creator/CSLewis.
* The point of Agatha Christie's ''Curtain''. [[spoiler: The person displaying this trait is actually an extremely timid person on the surface, taking revenge on others for being physically weaker than them this way]].
* The unnamed demon from Terry Brooks' ''[[Literature/TheWordAndTheVoid Running with the Demon]]'' and the changeling from its sequel ''[[Literature/TheWordAndTheVoid A Knight Of The Word]]''. The demon in particular seeks to corrupt all of humanity as part of [[UltimateEvil The Void's]] plan.
* Randall Flagg in ''Literature/TheStand'', who is very much a Devil-figure in the novel and [[strike:one]] ''many'' of Creator/StephenKing's most diabolical villains.
* ''Literature/ILucifer'' a novel written from the devil's perspective details his various efforts to corrupt mortal souls.
* [[OmnicidalManiac Ruin]] from ''Franchise/{{Mistborn}}'' isn't exactly encouraging people to be ''evil'' (he considers himself AboveGoodAndEvil), but he ''does'' work to make them more destructive, which usually amounts to the same thing. [[spoiler: Even the heroine was one of his pawns, at least for a while and without knowing it]].
* First Mate Cox in ''Literature/{{Nation}}''. He makes other people like himself.
* The BigBad himself, Kullervo, from ''CompanionsQuartet'' has this kind of effect on others having been able to convert the Seagullls, Cassandra Lang, and the Chimera amongst others.
* ''Literature/HarryPotter'': Lord Voldemort recruited [[spoiler:Quirrell]] this way, and presumably some other followers as well.
* ''Literature/ASongOfIceAndFire''
** Cersei Lannister is this to her brother Jaime. He isn't the nicest person anyway, but where she is concerned his moral compass (such as it is) shuts down completely. Once he's separated from here for a long period of time, [[HeelFaceTurn he begins to become a much better person]].
** [[MagnificentBastard Littlefinger]] is taking this role in regards to [[BrokenBird Sansa Stark]], teaching her how to evolve from pawn to player in the [[TitleDrop "Game of Thrones"]]. This in itself is a metamorphosis of sorts for Littlefinger, as judging by his backstory, he UsedToBeASweetKid and was corrupted by his severe BreakTheCutie process and the general [[CrapsackWorld Crapsack nature of Westeros.]]
* ''Literature/TheDresdenFiles''
** [[FallenAngel Lashiel's shadow]] fills this role, although [[spoiler: Harry corrupts her, for lack of a better term, more than she does him, and in the end she pulls off a HeroicSacrifice for him.]]
** ''Cold Days'' reveals that the ManBehindTheMan for most of the series is [[spoiler:the Outsider saboteur, Nemesis, whose machinations turned a good man into an abusive husband, four good FBI agents into vigilantes addicted to their new power, and turned two Fae Queens into threats against the natural world]].
* In ''Literature/LucifersHammer'', Sargent Hooker and his cannibal army qualify as this. People who they capture are forced to choose between helping to kill and eat other captives, or be killed and eaten themselves. Once they've done this, most don't ever feel they can go back, so they survive by committing themselves to their new comrades. (An interesting example, because we get to see how the army becomes corrupted, then becomes the The Corrupter in order to gain new recruits.)
* ''Literature/TalesOfKolmar'': Berys managed to become Archchancellor of the College of Mages through demon-summoning, and regularly when seeing students and established healers frustrated by their limits he would offer them greater power in exchange for a lock of hair and the promise of aid when he needed it. [[spoiler: He never tells them that said aid takes the form of sudden DemonicPossession and their magic feeding his, whenever he wants it.]]
* Wyrm in ''Literature/TheBookOfTheDunCow'' uses his DreamWeaver powers to persuade the old rooster Senex to father a son, although Senex is infertile, and makes the rooster desperate and dangerously obsessive. This son turns out to be the monstrous Cockatrice, who eventually [[spoiler: murders Senex when he realizes that Wyrm tricked him.]] Senex's corruption allows Wyrm to begin freeing himself from his prison beneath the earth.
* Humorously subverted with Crowley from ''Literature/GoodOmens'': he was the literal snake in the Garden of Eden and as a demon, corrupting hapless mortals is sort of his job description. He just goes about it in a very half-assed sort of way.
* ''Literature/ThoseThatWake'' has Man In Suit, who corrupts people through hopelessness.
* [[PsychoLesbian Calabah]], from ''Literature/TheMarkOfTheLion'', fulfills this role in [[spoiler:Julia�s]] life by making immorality seem glamorous; it�s implied that she has done this to many other young women.
* Lord Henry Wotton in ''Literature/ThePictureOfDorianGray''.
* In the third book in the ''Literature/WaysideSchool'' series, while the teacher is pregnant, there is a substitute teacher who fulfills this role, turning all the students against each other and creating a very tense and hate-filled classroom.
* Mark Twains' ''The Man That Corrupted Hadleyburg'' centers on a stranger who was subbed by people this "incorruptible" town. The stranger takes vengeance and would show them all how arrogant they are with nothing more than a sack of gold and a promise for it to be given to a person who would know a key piece of advice.
* The Dark Forest cats in ''Literature/WarriorCats'' have been convincing Clan cats to train with them and betray their Clanmates by joining their army. Out of all the Dark Forest trainees, only two stayed evil: Redwillow and Breezepelt.
* Melisande Shahrizai in ''Literature/KushielsLegacy''. She excels at corrupting powerful men & pushing them into committing treason.
[[/folder]]

[[folder:Live-Action TV]]
* ''Series/{{Arrow}}'': Malcolm Merlyn to [[spoiler:Thea,]] starting at the end of Season 2.
* In the third season of ''Series/AshesToAshes'', this is the whole motivation of Jim Keats. He wants to see Gene Hunt brought down and, resenting him for bringing good police officers under his sway, plans to turn the others against Gene. [[MoralDissonance It seems like he]] [[DesignatedVillain may have a point]]... then he grows into more of a ShadowArchetype of Gene Hunt, just as brutal but considerably more evil, and he becomes an almost Satanic figure. [[spoiler:Then he becomes an ''actual'' Satanic figure, as it's revealed the whole reason for his corrupting of the others was so that he could lure them down to Hell. It's that kind of show.]]
* Méléagant in ''Series/{{Kaamelott}}'' (seasons 4, 5 and 6). Who or what he is stays unclear, but it is hinted he's incredibly ancient. With a mix of guile and carefully-used magic powers, he works at corrupting Lancelot even further than he already was, and [[spoiler:push a depressive KingArthur toward suicide]].
* Mr. Morden on ''Series/BabylonFive'', who is introduced by going around the station asking the ambassadors [[ArmourPiercingQuestion "What do you want?"]]. His job under the Shadows is to find pliable people that he can tempt into a DealWithTheDevil by making them accept Shadow aid.
* ''Series/{{Smallville}}''
** {{Darkseid}} and his minions [[PropagandaMachine Godfrey]], [[StraightEdgeEvil Granny Goodness]], and ''especially'' [[NightmareFetishist Desaad]] fullfill this role in the tenth season, turning the entire world against the JLA while strengthening their own power in the process.
** Earth-2 Lionel did this to Lex, Tess, and Clark in his home universe, and tries it on Alexander when he makes his way to Earth-1.
* On ''Series/BurnNotice'', Larry's goal in life is to get Michael to cross the MoralEventHorizon and then go into business with him.
* ''{{Buffyverse}}'':
** A number of demons, including Moloch the Corrupter.
** Angelus, to a practically legendary degree.
* Barney Stinson on ''Series/HowIMetYourMother'' is a PlayedForLaughs version, especially towards Ted, and is constantly trying to get Ted to become [[TheCasanova more]] [[ManipulativeBastard like]] [[JerkAss him]]. However, when he's ''not'' doing this, Barney ''is'' a genuinely good friend.
* ''Series/TheTwilightZone'': The aliens in "The Monsters Are Due on Maple Street", [[spoiler:by way of suggestion]].
* An episode of ''Series/NinjaTurtlesTheNextMutation'' revealed that [[BigBad Dragonlord]] was this for the entire Rank race.
* In Season 4 of ''Series/{{Supernatural}}'', [[spoiler: Ruby]] is revealed to be one of these. Over the season she drives Sam away from his friends, gets him addicted to demon blood and tricks him into [[spoiler: releasing Lucifer from Hell.]]
* The Man In Black from ''Series/{{Lost}}''. Not only is his smoke form a ''literal'' corruption of the Light in the Island's center, his modus operandi is to corrupt people with nightmares and apparitions, or sometimes even infect them, so he can use them as pawns to defeat Jacob.
* [[BigBad Great Professor Bias]] of ''Series/ChoujuuSentaiLiveman'' sends tests to three students of Academia in the beginning, corrupting them and causing them to work for him. [[spoiler: It turns out one of them, Goh, was corrupted by the other two and was simply let in out of pity. As such, he was ultimately saved, though the others were not.]]
* Morgause from ''Series/{{Merlin}}''. Her first appearance is her attempting to get Arthur to kill Uther by telling him the truth about his conception. When that fails she whisks away [[spoiler: Morgana]] for a year and has corrupted her completely when they return in season 3.
* Klaus Mikaelson from ''Series/TheVampireDiaries''. He made the hero of the show (Stefan) do a FaceHeelTurn by bringing out his sociopathic alter ego, the Ripper.
* In ''Series/PrincessReturningPearl'' the role is played by conniving servants Rong Mou Mou and Gui Mou Mou.
* In ''Series/BreakingBad'', [[VillainProtagonist Walter White]] is this both in a {{Downplayed}} intentional fashion and in an unintentional fashion. While Jesse was already in the meth business, Walt coerces and manipulates him into doing things that he would never have considered doing beforehand. Unintentionally, Walt's influence has a similar effect on everyone around him. One of the writers noted, "Walt has corrupted everyone."
* [[Series/{{Hannibal}} Dr. Hannibal Lecter]]. More than the [[SerialKiller serial killing]] and the [[ImAHumanitarian cannibalism]], ''this'' is what he gets off on: [[PsychoPsychiatrist using his psychiatric training]] to manipulate his patients into become killers themselves. Sometimes he's motivated by [[ForTheEvulz morbid curiosity]], and other times he is, [[BlueAndOrangeMorality in his own twisted way]], being a good psychiatrist by helping people realise and accept their true self.
* In the ''Series/StarTrekVoyager'' episode "Alice", the titular ship through its female avatar plays this role to Tom Paris, getting him to steal parts from ''Voyager'' and to drive himself and the ship into a particle fountain which she calls "home." Near the end of the episode, Tom's girlfriend B'Elanna Torres acts as TheConscience to draw his attention away from ''Alice'' long enough to transport him out of the ship before it is destroyed.
* ''Series/PrettyLittleLiars'':
** CanonForeigner Cece Drake acted as this for Alison [=DiLaurentis=], giving her several of her traits and mannerisms, [[ConsummateLiar exacerbating her already considerable penchant for lies and manipulation]]. [[spoiler:It goes so far that the two of them act like twins at times, and Cece has been mistaken for Alison several times - particularly as Red Coat]].
** Alison herself acted as TheCorrupter to her GirlPosse, making them accessories to [[spoiler:arson and Jenna's (accidental) blinding]], encouraging Hanna's body image issues and eating disorder, and helping Aria [[spoiler:trash her father's office and frame it on Meredith, who he was sleeping with at the time]].
[[/folder]]

[[folder:Myths & Religion]]
* Literature/TheBible
** {{Satan}} as portrayed in the Gospels.
** The Serpent from Genesis, often identified with Satan.
* The demon Mara from Buddhist mythology, who led Buddha into temptation to prevent him achieving enlightenment.
[[/folder]]

[[folder:Pro Wrestling]]
* Wrestling/RingOfHonor stable Special K rapidly expanded its membership by drugging other wrestlers, particularly from JAPW, and turning them into drug addicts who only cared about their next fix. Wrestling/SamoaJoe was the one to finally put a stop to them. (The Spanish Announce Team, The Carnage Crew and Wrestling/LowKi all beat them up but Joe actually convinced them to do something else)
* This was the entire character of Sean O'Haire's last Wrestling/{{WWE}} gimmick -- he'd pop up to try and convince folks backstage to [[FaceHeelTurn turn heel]], in between vignettes urging ordinary people to do things like cheat on their wives simply for kicks.
* Héctor Garza was the one who turned Perro Aguayo Jr. evil in Wrestling/{{CMLL}} after Los Guapos had successfully got people to like him. Thus, Garza could be seen as the real {{big bad}} of Perros Del Mal and PDM Producciones, even though Jr. was the one in charge.
* Wrestling/JimmyJacobs has been this way in Ring Of Honor during his Age Of The Fall and Decade runs. [[Wrestling/HunterJohnston Delirious]], Adam Page and Ta'Darius among his "successes". He also played this role in Wrestling/{{Chikara}}, toward the promotion's first grand champion Wrestling/EddieKingston.
* This is the current character for Wrestling/{{Kane}}, as he's attempting to get Wrestling/JohnCena to "embrace the hate", and presumably, turn heel.
* Likewise [[Wrestling/TheWyattFamily Bray Wyatt]] not to only Cena but beforehand, Wrestling/DanielBryan.
* Wrestling/SummerRae acted as this towards Wrestling/SashaBanks on NXT. After suffering a few losses, Summer got into Sasha's head and convinced her she was worthless. After losing an important match to {{Wrestling/Paige}}, Sasha turned heel and allied herself with Summer. Charlotte later also turned heel to join them so we can assume Summer could also have done this offscreen to her too.
* Wresling/TheAuthority has been known to be this, convincing wrestlers to turn against their friends and loved ones. Examples include Wrestling/SethRollins and [[Wrestling/BellaTwins Nikki Bella]] being convinced to betray Wrestling/TheShield and Brie Bella respectively.
[[/folder]]

[[folder:Tabletop Games]]
* Gargauth, a literal god of corruption from the ''TabletopGame/ForgottenRealms'' world.
* Shedim from ''TabletopGame/InNomine'' '''are''' this trope; an alternate name for this particular type of demon is "Corruptors". They accomplish their corruption by DemonicPossession and driving their hosts to do things of escalating levels of evil every day, and the host thinks it was their idea in the first place.
* ''TabletopGame/OldWorldOfDarkness''
** The Followers of Set from ''TabletopGame/VampireTheMasquerade'' consider it their holy mission to tempt others into vice and sin.
** In ''TabletopGame/VampireTheRequiem'', they are replaced by the Mercy Seat (nicknamed {{Faust}}ians), a faction of Belial's Brood.
* Just about every Abyssal entity from ''TabletopGame/MageTheAwakening''. Through EvilIsEasy and EvilTastesGood they attempt to draw mages into a closer relationship with the Abyss in order to better work towards destroying, well, [[OmnicidalManiac everything]].
** In ''TabletopGame/MageTheAscension'', the Nephandi play basically the same role as the Abyssal below.
* Most any daemon or Chaos cultist could fulfill this role in ''TabletopGame/{{Warhammer 40000}}''. However, probably the most infamous Corrupter is Erebus of the Word Bearer's legion. Generally seen as the author of the Horus Heresy (and all the hell that brought on the Imperium and the rest of the galaxy), Erebus turned his Primarch to Chaos when Lorgar was having his CrisisOfFaith and also was the driving force behind the corruption of Horus himself.
** Other notable Corrupters from the setting include Calas Typhon of the Death Guard (who unleashed the Destroyer Plague on his legion, turning them into Plague Marines and becoming Typhus the Traveller) and Ahzek Ahriman of the Thousand Sons (who, in an odd twist, was attempting to ''save'' his legion from corruption when he became their ultimate undoing).
[[/folder]]

[[folder:Theater]]
* Arguably Cassius in ''Theatre/JuliusCaesar'' who persuades Brutus to join the conspiracy to kill Caesar by poisoning his mind and telling him that Caesar wants to make himself a dicator. However, there is debate other whether Cassius himself actually believes what he tells Brutus.
* ''Theatre/{{Macbeth}}''
** LadyMacbeth has some elements of this. See the trope for details.
** Also the Three Witches, who are there just to start the title character's headlong rush down [[JumpedOffTheSlipperySlope the slippery slope]]
* Iago of ''Theatre/{{Othello}}'' who feeds the title character's jealousy about his wife until it destroys him, [[ForTheEvulz just because he can]] (yes, he was passed over for a promotion, but it's generally accepted that his actions are [[DisproportionateRetribution too incredibly disproportionate to the slight for it to be his underlying motivation]]).
[[/folder]]

[[folder:Video Games]]
* [[spoiler:Mephistopheles, the BigBad of]] ''VideoGame/NeverwinterNights: Hordes of the Underdark''. Especially towards your followers...
* Alexander from ''VideoGame/AmnesiaTheDarkDescent'' fills this role quite well, especially with respect to [[spoiler:Daniel. Taking advantage of Daniel's growing paranoia, he transforms him from a naive young man to an AxCrazy [[ColdBloodedTorture torturer]].]]
** Then again, one could argue that both men had already been corrupted by [[spoiler:[[AdvancingWallOfDoom the Shadow.]]]]
* While Chaos is the BigBad of ''VideoGame/DissidiaFinalFantasy'', he is just as much a victim of the GroundhogDayLoop as everyone else. [[spoiler:His [[TheDragon dragon]] Garland]], on the other hand, remembers every iteration of the cycle and always pushes Chaos into waging war on Cosmos.
* Mephiles in ''Sonic 2006'' fills this role, or tries to. He tries to tempt Shadow into turning evil again to "help Mephiles" in a desire for revenge, when all Mephiles actually wants to do is destroy everything. He also manipulates Silver into getting him to kill Sonic, which sticks for most of the game until Shadow convinces him of better. Luckily, it turns out Shadow is the only character with a clue. [[spoiler:At the end, Mephiles takes matters into his own hands, and kills Sonic.]]
* ''VideoGame/KnightsOfTheOldRepublicII''
** If you're playing Light-Sided, Kreia can ''definitely'' be this, viciously berating selfless actions, inflicting MindRape on your companions, and encouraging you to "use" and "discard" everyone like tools to advance yourself.
** [[LightIsNotGood Atris]] repeatedly accuses the Exile of being this to the Handmaiden, after she decided to stowaway on the ''Ebon Hawk'' to join their quest, then later broke their oath by asking the Exile to teach her the ways of the Jedi.
** The Jedi Exile can implicitly cause people to do things they normally wouldn't. [[SourSupporter Vrook]] remarked that though The Exile was never a very powerful Jedi they were remarkably good at making people seeing their way, by unconsciously creating and drawing on force bonds even with people they'd just met. For an example Mira the bounty hunter never usually kills, but is unhappy to note that she doesn't hold back when fighting in The Exile's party.
* ''VideoGame/StarWarsTheOldRepublic''
** You play this role as a Sith Inquisitor, particularly during the Taris storyline in which you recruit a Jedi Padawan into your team by staging an ambush in which you come to her rescue, and then goad her {{Hot Blooded}} tendencies in a series of follow on encounters until she becomes convinced that she was {{Evil All Along}}.
* "Master User" J. D. Thorne in ''VideoGame/TronTwoPointOh'' was a User sent into {{Cyberspace}} without the necessary protocols to keep him stable, turning him into a living computer virus that seeks out Programs and twists them into Z-lots.
* ''Franchise/TheElderScrolls''
** Molag Bal, the Daedric Prince of Domination. He's even called The Corrupter in-universe.
** Most of the overtly evil Daedric Princes dabble in this role in one way or another, relishing every chance to turn a mortal (particularly a [[PlayerCharacter Hero]]) to their way of thinking.
* Xana from ''VideoGame/DarkMessiah'' spends the entire game trying to convince Sareth to accept his demonic heritage, all the while making pretty blatant come-ons and innuendo (she is a succubus after all). She also tries to convince him [[spoiler:to ''not'' free the Demon Sovereign, and instead claim the Skull's power for himself, with her at his side.]]
* Skelter Helter and Pizza Batt Jr. try to be this towards Travis in ''VideoGame/NoMoreHeroes2DesperateStruggle'', making him feel the pain he made them feel and become a monster just like them. [[spoiler:They fail at killing the remaining friends he has, however]], and also sort of forgot that Travis was already pretty corrupt to begin with.
* When [[spoiler:Adachi]] tried this in ''VideoGame/{{Persona 4}}'', the main cast [[spoiler:pointed out how childish and pathetic his view points were.]] [[spoiler:He]] [[NotGoodWithRejection does not take it well.]]
* ''Franchise/ShinMegamiTensei'' has the ultimate example in Lucifer. He [[SatanIsGood may not be evil]], but that does ''not'' mean he's selfless or entirely benevolent. In fact, it's hinted by WordOfGod that Lucifer's true role is the tester of the human spirit, the entity meant to embody this for Humanity as a whole, offering, taking away and generally gambling with power as only gods can.
* From the ''Franchise/KingdomHearts'' series, we have Xehanort. In [[VideoGame/KingdomHearts the first game]], his Heartless and [[Disney/SleepingBeauty Maleficent]] turn Riku into a RivalTurnedEvil in order to steal his body. In ''VideoGame/KingdomHeartsBirthBySleep'', his original incarnation convinces Terra that it's okay to use the power of Darkness because of the BalanceBetweenGoodAndEvil for the '''exact same reason''', then uses Ansem the Wise's own apprentices to overthrow him before turning them into Nobodies. In the [[VideoGame/KingdomHeartsII the second game]] his Nobody, Xemnas, recruits an amnesiac Roxas into Organisation XIII to help unlock Kingdom Hearts by implying that Roxas can reclaim his own heart in the process, though his true goal is to TakeOverTheWorld. ''KingdomHeartsDreamDropDistance'' gives us his past self Young Xehanort, who combines this trope with MindRape and {{Troll}} in order to turn [[spoiler: Sora]] into his 13th vessel. [[spoiler:And according to a flashback, Y. Xehanort was turned to evil by his aforementioned time-travelling Heartless!]]

[[folder:Web Comics]]
* Anakin is this in ''Webcomic/DarthsAndDroids'', particularly focusing on Palpatine in a reversal of their roles from [[Franchise/StarWars the source material]]. [[spoiler:Unfortunately for him, he succeeds a little too well with Palpatine...]]
* Doc Scratch from ''Webcomic/{{Homestuck}}'' is this for a species, turning the Trolls of Alternia from PerfectPacifistPeople into the ultimate [[ProudWarriorRaceGuy Warrior Race]].
* The IFCC from ''Webcomic/TheOrderOfTheStick'', who may have a behind-the-scenes EvilPlan going on, but are also just as interested in claiming souls as any other fiends. Sabine states that she'd seen them take down mortals way more righteous than TrueNeutral Vaarsuvius.
* In ''Webcomic/{{Sinfest}}'', [[http://www.sinfest.net/view.php?date=2012-01-29 Baby Blue accuses the Sisterhood of this.]]
[[/folder]]

[[folder:Web Original]]
* ''Roleplay/TheGunganCouncil'' has many Sith, like Darth Apparatus, tempting Jedi to the dark side.
* WebVideo/TheNostalgiaCritic has been established in-universe and out as a horrible influence on people. Problem is, he doesn't know he's doing it and he's the one who usually ends up getting killed, raped or otherwise hurt in some way.
* ''Literature/{{Worm}}''
** Tattletale is this to Taylor, offering her friendship without reservation and a place in her supervillain gang, which given Taylor's status as a bullied fifteen-year-old almost immediately earns her affection. This example is notable in that Tattletale genuinely does want what's best for Taylor, and thinks that she can get a sense of fulfillment and empowerment with the Undersiders that she won't get if she just keeps going to school and being bullied.
** Later, Taylor herself gains this reputation after [[spoiler:she convinces both Parian and Flechette to defect to the Undersiders.]]
** Jack Slash ''excels'' at this, but his motives aren't nearly as benign. He even [[spoiler:talks [[PhysicalGod Scion]] into pulling a FaceHeelTurn and deciding to wipe out humanity.]]
* Sigma and to a lesser extent Gamma played this role in Machinima/RedvsBlue, using Maine's rage to lead him to being controlled by his own AI, Carolina's jealousy of Texas causing her to [[spoiler: try to use two AIs at once]], trapping [[spoiler: Alpha Church]] in a simulation to torture him and playing an indirect but major role in the eventual [[spoiler: destruction of Project Freelancer itself]] from their search for the [[spoiler: Alpha]] to combine with.
* [[spoiler: The Forbidden Power]] in {{TOME}} does this to Alpha by convincing him that he needs it to keep his friends.

[[folder:Western Animation]]
* Slade from ''WesternAnimation/TeenTitans'', especially in Seasons One and Two.
* Darkseid from ''WesternAnimation/SupermanTheAnimatedSeries'' has elements of this, though he has bigger plans than ''just'' turning Superman to his side.
* Nerissa from ''WesternAnimation/{{WITCH}}'' has elements of this, though she's unusual in that she's a WellIntentionedExtremist -- it's just that she's ''also'' a big-time control freak and finds people's moral flaws to be an easily-exploitable weakness she can use to control them.
* In ''WesternAnimation/AvatarTheLastAirbender'', [[MagnificentBitch Azula]] fits this. While she doesn't bring down someone who was good, [[spoiler:she did corrupt her brother Zuko right before he could complete his HeelFaceTurn at the end of Season 2. Despite their uncle's protests he joined her. Though he did eventually make up for it with a real HeelFaceTurn in Season 3.]]
** Azula also manages to turn the [[SecretPolice Dai-Li]] against the Earth Kingdom, understanding they follow who looks most powerful.
** The second season of ''WesternAnimation/TheLegendOfKorra'' has [[spoiler:Unalaq, a dark priest]] who can turn normally good or neutral spirits into Dark Spirits.
* From the 2010 French AnimatedAdaptation of ''WesternAnimation/TheLittlePrince'', [[BigBad the Snake]] is this trope in its purest form. His modus operandi is to compel the most important person on every planet to indulge into their whims, with always disastrous results for their world. Naturally, he attempts it with the title hero too, trying to convince him to return to Asteroid B612 and leave the Snake free to corrupt people.
* ''WesternAnimation/SouthPark'': Cartman is exceptionally adept at pulling along otherwise decent, if not pottymouthed kids into his horrible schemes. Usually happens to Butters and Kyle.
** "Crack Baby Athletic Association" has Cartman corrupt the normally morally uptight Kyle to the point that Stan calls Kyle on sounding just like Cartman.
* ''WesternAnimation/XiaolinShowdown''
** Chase Young spends almost the entire second season working to corrupt Omi and convince him to join the forces of evil.
** Third season introduces Hannibal Roy Bean, the one who successfully corrupted Chase.
** Wuya successfully turned Raimundo against his friends by offering him power and respect after he felt snubbed by Master Fung near the end of the first season. Hannibal tried to corrupt Raimundo again but failed miserably.
* Discord from ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' does this to most of the Mane Six [[ForTheEvulz for fun]] [[spoiler:and to keep the Elements of Harmony powerless]]. When [[spoiler:Fluttershy]] proves [[IncorruptiblePurePureness immune to his mindgames]], he throws a [[VillainousBreakdown hissy fit]] and forcefully brainwashes her anyway.
** [[spoiler:He's later on the receiving end of this trope in the Season 4 Finale by Lord Tirek]].
* HIM in ''WesternAnimation/ThePowerpuffGirls'' could easily end the planet if he wanted to. He chooses his schemes based on tearing down the morality of the Girls, especially Bubbles, and admits defeat even when he doesn't have to, if the plan fails.
* Mumm-Ra in WesternAnimation/ThunderCats2011 shows some signs of this. He manages to use Grune's ambition and paranoia to make him betray the Cats, and he uses the Lizards' hatred of the Cats to recruit them into his army. [[spoiler: And in the finale it's revealed Mumm-Ra used a dying Pumyra's hatred of Lion-O for supposedly abandoning her to make her work for him as TheMole.]]
