[[caption-width-right:304:So [[EvilMentor wise]], so [[TokenEvilTeammate helpful]], he makes [[AmbitionIsEvil achieving your dreams]] a [[SlowlySlippingIntoEvil downhill trip]].]]

->''"He doesn't measure his wealth in private jets, but purchased souls."''
-->-- '''Frank Underwood''' on Raymond Tusk, ''Series/HouseOfCardsUS''

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 BreakThemByTalking and TheReasonYouSuckSpeech 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.



[[folder:Anime & Manga]]
* Schneizel el Britannia from ''Anime/CodeGeass'' has a knack for this, compelling a distraught scientific genius to build a FantasticNuke and turning a sweet young girl against her brother.
* Embryo from ''Anime/CrossAnge'' has a definite knack for this by [[BaitTheDog baiting any desperate soul]]. Midway through the series, [[spoiler:he resurrects and turns Chris against her allies who thought abandoned her, rescues Salia and tempts her with the possibility of upstaging Ange, and resurrects the kids Ersha was protecting and gives her another chance to protect them under his service.]]
* 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]].
** 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]].
* The resident VillainProtagonist Aur from ''LightNovel/MaouNoHajimekata'' does it with an incredibly perverse touch, some women join his cause (and harem) because they don’t like humanity either or are just indifferent towards them; women who saw Aur as they evil being he is however are met with many phases of brainwashing ''through sex'', Aur implants them memories of him always being a lover of theirs, or impersonates their actual lover if the woman in question is already engaged, at any case it ends with the women falling to perverse lust and seeing Aur as the only man in their lives, completely agreeing and assisting him with his evil deeds.
* 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.
** Ryuk plays this role in the TV drama, in which he deliberately drops the book so Light is the one to find it (rather than it being a coincidence like in the original series) and goads him into continuing to use it when Light hesitates.
* 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.
* ''Manga/TokyoGhoul'' plays with this quite a bit.
** 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.
** In the sequel, [[BigBad Eto]] twists numerous individuals through a combination of mind games, torture, and XanatosSpeedChess. She slowly worms her way into Hinami's life, convincing her to [[CorruptTheCutie seek power]] through joining Aogiri and becoming one of their most valuable members. [[spoiler: Takizawa]] and Kanae both end up twisted through her influence, and get used as her [[TheDragon Dragons]] in a larger scheme involving Kaneki. Her various manipulations have resulted in him [[spoiler: regaining his memories, abandoning his comrades and adopting an utterly cold and ruthless persona]]. It isn't clear what her goal in doing this is, but she seems ''awfully'' pleased with the changes her influence has wrought.
* ''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.
* ''Manga/BlackButler'': It's implied that Sebastian's influence in Ciel's life is making the already cynical Ciel even more ruthless.
* Malty in ''LightNovel/TheRisingOfTheShieldHero'' is personally responsible for each of the Heroes awakening their Curse series, resulting in three temporarily going insane and [[spoiler:Motoyasu going ''permanently'' bonkers]]. The extent of her involvement in the King's fall from grace and [[spoiler:Tact]]'s insanity are uncertain.
** [[spoiler:Medea]] acts as this on a global level, corrupting the defenders of [[spoiler:all eight worlds]] to weaken them through in-fighting. Even her own minions are corrupted, rendered insane and dangerous to everyone except her.
* ''Franchise/DragonBall'':
** It is stated by Master Roshi that Shen became corrupted after witnessing King Piccolo's cruelty and humiliating his master. Also, part of the reason why Piccolo frees all the prisoners and abolished all laws is to stroke the darkest aspects of humanity.
** In the Japanese text, Piccolo humored twisting Gohan into his image and turning him against his father. [[{{Irony}} The opposite ended up happening]].
** For a straight example, Frieza. In ''Anime/DragonBallSuper'' Tagoma went from being a NobleDemon and the OnlySaneMan, to a monster who is just as cold and ruthless as Frieza after surviving four months of [[BeingTorturedMakesYouEvil torturous training sessions]]. This in itself is a CallBack to how Frieza corrupted Vegeta to be more coldblooded even by Saiyans' standards by nurturing his dark tendencies and [[FantasticRacism treating him like trash for being a Saiyan]].
* Dartz, and for that matter, the Seal of Orichalcos, from ''Anime/YuGiOh'' do this to anyone who activate its power by bringing out all of the darkness in one's soul.
* Ferid of ''Manga/SeraphOfTheEnd'' is mentioned by Crowley to have the kind of beauty and personality that corrupts people. Indeed, he enjoys killing and screwing people over ForTheEvuls and playing mind games with those he likes, unfortunately for Krul, Mika, and Yuu.
* In ''Manga/{{Kasane}}'', Habuta largely plays this role to the title character. He's so obsessed with making her an actress of her mother's caliber that he constantly encourages her to let go of her qualms and remorses, and throw morality in the bin to achieve success. This includes [[spoiler:keeping a comatose Nina in a dark room for a full year to "use" her face at will, or tricking Nina's father into thinking his wife (who rightfully suspects that their daughter is an impostor) has gone insane.]] Each time, Kasane expresses some doubts, and each time Habuta gives her a little push.
* ''Manga/OnePiece'' has the senior executives of the Donquixote Pirates, who helped Doflamingo become who he is today. While he was already a fairly rotten kid, they're the ones who fed his ego, gave him his signature gun and Devil Fruit, and ''razed a town to the ground because its uneven pavement made Doflamingo trip.'' Trafalgar Law lampshades how twisted it is, since they think that Doflamingo values them as much as they value Doflamingo when really their encouragement has made it so Doffy will always consider himself first and deep down see them as expendable.
** Shockingly, Big Mom's head chef Streusen is revealed to have been this to her. As a very young child Charlotte Linlin was terrifyingly strong and had an eating disorder that led to her going on hunger fueled rampages. She also trended towards being ObliviouslyEvil, thinking she was helping the people she was hurting. The chef was so impressed by her power that he took her in and channeled that power in the direction of piracy by telling her she could carry out her dreams that way.

[[folder:Comic Books]]
* ComicBook/{{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.
* A mid-70s Marvel villain (who faced off against ComicBook/{{Nova}} and Thor) was actually called The Corruptor- he was a worker at a factory that made pharmaceuticals until a fire doused him in a mix of stuff -- it made his hateful and violent parts of his psyche take full control, granted him the power to have others go crazy or follow his orders just by touching them, [[ArsonMurderAndJaywalking and turned his skin a dark blue and his eyes red]].
* Creator/TheJoker is this to Harleen Quinzel, a promising psychiatrist who [[LoveMakesYouEvil falls]] [[LoveMakesYouCrazy in love]] with him after hearing one of his many [[MultipleChoicePast fabricated back stories]] and becomes his right-hand woman, Creator/HarleyQuinn.
** While Jason Todd was definitely an AntiHero from the beginning, it was his death at the Joker's hands and his thirst for vengeance after [[DeathIsCheap being brought back]] that ''really'' pushed him [[FaceHeelTurn over the edge]].
** Jason really wasn't, he was impulsive as Robin but he only had one instance where he slipped into AntiHero territory, but the Joker murdering him and his resurrection did a number on him, and Talia al Ghul only made things worse with finding him teachers to train him to be a better killer and wanting revenge against Bruce herself by the end of ''Comicbook/RedHoodTheLostDays''.
** DependingOnTheWriter, Joker's burning ambition is to prove to people in general (and Batman in particular, though sometimes he'll focus on other individuals like [[ComicBook/TheKillingJoke Commissioner Gordon]]) that they'd be just as insane and twisted as he is if they were pushed far enough. This became key to his entire persona in the Nolan films.
* The main villain of ''ComicBook/TheUltimates2015'' is one of these on a multiversal scale. The opening monologue of the second series elaborates that it's draining life, hope and joy from the universe. By that point, it's also corrupted Master Order and Lord Chaos, [[spoiler:as part of its plan to destroy the current multiverse.]]

* ''FanFic/{{Fade}}'': After reading his half of the Kira story and becoming addicted to the Death Note, L resolves to become TheMentor to Kira and teach him how to use the Death Note the "right" way. However, once Kira (Light) shows himself nowhere near as corrupted as his story counterpart (sticking only to the worst of criminals and no one else), L, angered that his "villain" isn't acting like the villain he needs to stop, [[spoiler:uses his Death Note to kill criminals undeserving of death, both to frame Light and [[InsaneTrollLogic to convince him to kill like that so L can redeem him and teach him to use the Death Note "correctly"]]]]. After ''that'', any illusions that L will be TheMentor to Light are shattered for both the audience and Light himself once he figures out what L has done. The only person L is really fooling is himself.
* ''FanFic/TheUzumakiTalesReturnOfTheWhirlpool'': PlayedForLaughs. Jiraiya and Kakashi corrupt Naruto and Sasuke, respectively, by turning them into perverts. Naruto is designated as the next writer for the Icha Icha series after Jiraiya's death or retirement (whichever comes first) while Sasuke becomes addicted to the series like Kakashi is. Understandably, once their girlfriends find out, they are ''not'' happy. Jiraiya was also the one to teach a young, innocent Hiashi about the... ''[[CovertPervert advantages]]'' of having a Byakugan.

[[folder:Films -- Animation]]
* The anthropomorphic fox J. Worthington Foulfellow in the Disney version of ''Disney/{{Pinocchio}}''.
** The coachman even more so.
* ''Disney/{{Frozen}}'': While it's known that [[spoiler:Prince Hans]] tried to seize control of Arendelle through manipulation, the TieInNovel ''Literature/AFrozenHeart'' reveals that [[spoiler:[[GreaterScopeVillain his father, the king of the Southern Isles,]] manipulated and corrupted most of his thirteen sons into becoming his sycophantic enforcers. It took an attempt to escape his father's abusive and toxic influence for Hans to finally resort to his family's twisted actions that he once refused to do.]]

[[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...in fact he [[HeelFaceTurn ''de-''corrupted his original corruptee]] in his attempt against his son).
** Most Sith Masters in the Franchise/StarWarsExpandedUniverse are like this too, particularly when [[WeCanRuleTogether recruiting apprentices.]]
** Supreme Leader Snoke, the leader of [[TheRemnant the First Order]] in ''Film/TheForceAwakens'', corrupted Kylo Ren [[spoiler:(formerly called Ben Solo)]] at a young age, when he was still training under Luke Skywalker, culminating with Kylo eradicating the New Jedi Order.
* ''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.
* Hornsby, from ''Film/TheMiracleWoman'', manipulates Florence to believe that she needs to get even with her father's former churchgoers. Hornsby's only motivation is that he knows he can make a lot of money, but only with Florence's help.
--->'''Hornsby''': You think you beat those people, don't you? Well you didn't. There's only one way to lick a mob, sister, join them. You're not a hypocrite if you admit it. Most of the trouble in this world comes from people who have beliefs. The answer is: don't have any! If you have none, you can assume the ones that happen to pay.
* ''Film/TheWorldOfKanako'': [[spoiler:Akikazu's daughter Kanako]] gets the narrator being caught and handed to a [[spoiler:prostitution ring]], where he gets physically abused and later beaten up and thrown into a river. He now wants vengeance and follows a girl from the gang and tortures her to get [[spoiler:Kanako’s]] location. However, when they finally meet, he is unable to [[spoiler:kill her as he is still in love with her]].
* ''Film/CloudAtlas'': Old Georgie, the future Hawaiian imagery of the devil. Zachry's tribe have a strong storytelling culture and smoke a ''whole'' lot of weed, so for them, seeing and hearing Old Georgie is as normal as anything. He very appropriately looks like a Hawaiian witch doctor in the film version.

* 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 the epitome of this in Middle Earth. From corrupting Sauron from a beautiful servant of the Valar to the nightmare he is now, to torturing elves into orcs in some versions of the story, all the way to pouring his will into Arda so that it has more potential for evil to rise and flourish.
** 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.
** The very essence of the One Ring is to bring out the worst in a person by catering on his/her desires and twisting them into selfishness and narcissism. Sauron is through it more and of a Deceiver and a Corrupter than ever.
** Gríma Wormtongue was 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/RunningWithTheDemon'' and the changeling from its sequel ''Literature/AKnightOfTheWord''. 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'' is a questionable one.
* 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.
* Creator/MarkTwain's "The Man That Corrupted Hadleyburg" centers on a stranger who was snubbed by the people of this "incorruptible" town. The stranger takes vengeance and shows 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.
* Ellsworth Toohey in ''Literature/TheFountainhead'' dedicates himself to dragging the talented into averageness.
* 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 and pushing them into committing treason.
* Bergdahl in ''Literature/TheDinosaurLords'' to Falk. He manipulates him into going further along with the plan, riles him up to rape Melodía (which is the only thing Falk resists) and pushed Falk further down the slippery slope whenever the man hesitates to KickTheDog.
* Eugen von Frenzel in ''Literature/ThePearlandtheCarnelian'', being a Nazi propagandist, acts this way towards Lady Lucy - a [[SpiritedYoungLady curious, intellectual young noblewoman.]]
* The Crippled God from ''Literature/MalazanBookOfTheFallen'' specialises in bringing out the worst in people, typically [[DealWithTheDevil offering them exactly what they want]] in exchange for their inclusion in his House of Chains. He has taken up the cause of recruiting 'broken' individuals that can emphasize with him, but if the victim isn't broken already he has no problem breaking them.
* In the ''Literature/DreambloodDuology'', the Prince does his best to make Ehiru stray from Hananja's path. Since Ehiru only escaped being killed senselessly as a child because he had already been chosen by Hananja, the prospect of stopping the internal infighting of the royal family has its appeal. However, [[spoiler:his brother's]] methods go against everything Ehiru believes in.
* In ''Literature/TheSpiritThief'', the Master of the Dead Mountain corrupts, or at least tries to corrupt, all demonseeds, starting with offering useful advice and bursts of power and slowly increasing both until the target surrenders to DemonicPossession.

[[folder:Live-Action TV]]
* ''Series/ItsAlwaysSunnyInPhiladelphia'' has the main characters: Dennis, Dee, Mac, Charlie, and Frank; AKA “The Gang”. Just interacting with the Gang consistently causes SanitySlippage or some other life-ruining outcome, almost completely without fail. Victims of the Gang's corruption include Rickety Cricket (goes from a clean-cut priest to a horribly mutilated CrazyHomelessPerson), Maureen Ponderosa (has become a ''[[PettingZooPeople literal]]'' CrazyCatLady), Bill Ponderosa (Dee helped ruin his marriage, and with Frank as his AA sponsor he's become a drug-fueled suicidal maniac), Mac's dad Luther (whose murder case was horribly mismanaged by Mac and Charlie, [[WhatHappenedToTheMouse which may have gotten Luther killed in prison]]), The Waitress (is driven insane by Charlie's stalking and Dennis' sociopathic manipulation, and also gets fired from her job, causing her to sink further and further into poverty), and The Lawyer (despite outsmarting the Gang on multiple occasions to his own benefit, they've ruined at least one of his marriages and indirectly caused his eye to be pecked out in court).
* ''Series/{{Fargo}}'' has Lorne Malvo, who drives innocent do-gooders into [[ProtagonistJourneyToVillain evil]], [[SanitySlippage insanity]], and [[ArsonMurderAndJaywalking general mischief]] for no apparent reason other than fun. [[spoiler: The finale reveals that his suitcase is full of tapes recording his favorite victims' pleas and accusations toward him, which he spends his time alone listening to.]]
* ''Series/{{Gotham}}'': Theo Galavan is being set up to be this to Gotham in general and [[spoiler:Jim]] specifically.
* ''Series/{{Arrow}}'': Malcolm Merlyn to [[spoiler:Thea,]] starting at the end of Season 2.
** Spin Off series ''Series/TheFlash2014'' has Zoom try to pull a NotSoDifferent with Barry.
** Somewhat PlayedForLaughs in the ''Series/LegendsOfTomorrow'' episode [[Recap/LegendsOfTomorrowS2E5Compromised "Compromised"]], where Mick encourages NiceGuy [[TheAtom Ray Palmer]] to act more like [[JerkWithAHeartOfGold Jerk with a (really well-hidden) Heart of Gold]] Captain Cold, [[spoiler: who is currently dead]]. However, Ray's attempts at acting like Cold [[spoiler: just upset Mick, since they remind him of his dead friend]] and he tells Ray to knock it off and be himself.
* 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}}''
** {{ComicBook/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.
* ''Franchise/{{Buffyverse}}'':
** A number of demons, including Moloch the Corrupter.
** Angelus, to a practically legendary degree.
** The Senior Partners of Wolfram and Heart could have squashed Angel like a bug at any point during the series, but they care more about [[WeCanRuleTogether trying to get Angel on their side during the Apocalypse]] than they do about the damage he is doing to their organization. In the final episode Angel finally pisses them off enough that they stop trying and decide to [[WhyDontYouJustShootHim just send everything they have at him to take him out.]]
* 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.
* ''Series/{{Supernatural}}''
** In season 4, [[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 [[spoiler:tricks him into releasing Lucifer from Hell.]]
** Crowley is this to a lesser extent for Dean as the series goes on. In Season 11 he briefly fantasizes about a world where everyone is evil, but then quickly decides that he ''doesn't'' want that because the ''real'' enjoyment comes from tempting good people into doing evil.
* 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 {{serial kill|er}}ing and the [[ImAHumanitarian cannibalism]], ''this'' is what he gets off on: [[PsychoPsychologist 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 Meredith for it, who he was sleeping with at the time]].
* ''Series/KamenRiderExAid'': This is usual part of conversations between {{P|sychopathicManchild}}arado and [[TheHeart Emu]]. Kind doctor he is, all that matters to Emu is saving his patients and ''overally'' making them feel better. On the flip side, all that matters to Parado is playing ({{video|gameTropes}}[=/=]{{m|anipulativeBastard}}ind) games without care if anyone gets hurt. He tries to convince Emu to abandon his mission and play with him at every other turn. [[IncorruptiblePurePureness Emu]] is not amused and doesn't off Parado because a) he is busy with doctor stuff and b) he believes that Parado can be better. [[spoiler: By the end, Emu basically acts as [[InvertedTrope TheUncorrupter]] for Parado, pulling him into HeelFaceTurn.]]

[[folder:Myths & Religion]]
* Literature/TheBible
** {{Satan}} as portrayed in the Gospels.
** The Serpent from Genesis, often identified with Satan.
** James the Lord's brother warns believers in [[Literature/EpistleOfJames his epistle]] not to accuse God of being this by saying "I am being tempted by God", for he says God cannot be tempted by evil, nor does He tempt anyone.
* The demon Mara from Buddhist mythology, who led Buddha into temptation to prevent him achieving enlightenment.

[[folder:Pro Wrestling]]
* The Masked Miser Angelo Poffo was usually a baby face, both as a wrestler and as manager, in his earlier years but could easily be convinced to turn heel by evil managers Bronco Lubich, particularly during his Chicago run of the 1950s, and [[Wrestling/BobbyHeenan Bobby "The Brain" Heenan]], who paired him together with Chris Markoff to form "The Devil's Duo" TagTeam during the 1960s.
* Wrestling/KevinSullivan took hold of a mild mannered photographer from New York passing through [[Wrestling/NationalWrestlingAlliance Championship Wrestling From Florida]] and transformed him into [[Wrestling/PaulHeyman Paul E. Dangerously]], who remained a self serving menace wherever he went from then on out. Sullivan also turned the innocent reporter Trudy Herd into the deranged Wrestling/LunaVachon, though that was more like BrainWashing since he had knocked her unconscious first and though the name stuck Luna would eventually go through a much more convincing HeelFaceTurn than Paul ever did away from Sullivan.
* Wrestling/VinceMcMahon tried to corrupt Wrestling/StoneColdSteveAustin in 1998, but failed. He was more successful in 2001.
* Pin up lady Miss Maulie, in addition to being a seductress, has a reputation for leading people towards gambling and alcoholism.
* 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 faces 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.
* Michael Kovac approached the distressed, the frustrated, the luckless and the like with promises of help which, if he had his way, lead to them joining him as Apostels of Hell.
* This is the current character for Wrestling/{{Kane}}, as he's attempting to get Wrestling/JohnCena to "embrace the hate", and presumably, turn heel. In the end, it was Wrestling/EveTorres who became the heel instead, although Kane likely didn't intend of that happening.
* Likewise Wrestling/BrayWyatt and Wrestling/TheWyattFamily not to only Cena but beforehand, Wrestling/DanielBryan. It worked on Bryan (although only for two weeks) but not Cena.
* Wrestling/WadeBarrett during his [[Wrestling/TheNexus Nexus]] days, tried to corrupt Cena as well. Once again, he failed.
* 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 (or maybe Sasha) could also have done this offscreen to her too.
* Wrestling/JohnLaurinaitis did this to Wrestling/TheBigShow in 2012.
* Wresling/TheAuthority has been known to be this, with Wrestling/TripleH and [[Wrestling/StephanieMcMahon Stephanie]] convincing wrestlers to turn against their friends and loved ones. Examples include Wrestling/SethRollins and [[Wrestling/BellaTwins Nikki Bella]] being convinced to betray [[Wrestling/DeanAmbrose the rest]] [[Wrestling/RomanReigns of]] Wrestling/TheShield and Brie Bella respectively. The Authority also got Wrestling/TheBigShow to go to the heel side at Survivor Series 2014.

[[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.
* Creator/GamesWorkshop games:
** Any daemon or Chaos cultist could fulfil this role in ''TabletopGame/{{Warhammer}}'', ''TabletopGame/WarhammerAgeOfSigmar'' and ''TabletopGame/Warhammer40000'' with the minions of Tzeentch, god of fate, and Slaanesh, the god of pleasure, being particularly adept at turning the innocent from the path of righteousness.
** ''TabletopGame/{{Warhammer 40000}}'' specific examples:
*** Probably the most infamous Corrupter is Erebus of the Word Bearers legion. Generally seen as the instigator 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. From there the corruption spread throughout the Word Bearers and then to other legions.
*** Calas Typhon of the Death Guard, who manipulated his legion into having the Destroyer Plague unleashed on them, setting them up to turn to Nurgle and become Plague Marines. Typhon was rewarded by becoming Typhus the Traveler, a Chaos Champion of [[PlagueMaster Nurgle]].
*** 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).
** When Sigmar’s followers returned to the Mortal Realms in ''TabletopGame/WarhammerAgeOfSigmar'', the Herald of Tzeentch known as the Changeling disguised itself and moved through the new cities that had been established, leading countless followers of the God-King astray with its lies and promises of power

* 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: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]].]]
* 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 the Dark in ''VideoGame/SonicTheHedgehog2006'' 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.]]
* [[DemonLord Mephisto]] from ''{{VideoGame/Diablo}}'' fits this. His influence was so strong that even after he was [[SealedEvilInACan sealed away]] he was able to corrupt the originally good and noble Church of Zakarum into a [[CorruptChurch zealous, murderous and warmongering Church]]
* ''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}}.
** A Sith Warrior has the ''option'' of doing this to Jaesa through TraumaCongaLine. She ends up completely insane if you go down this route, but even the kinder path exposes her master as a fraud, sends her parents to a comfortable life in the Empire, and convinces her the Sith are a better deal.
* "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. In ''Killer App'' a Program called The Corrupter is turning Programs into drones on the order of his User, masking his presence from the ICP forces and civilians so they can't recognize him as a threat. Tron is sent to cut off the malevolent User's access while Mercury takes down the Corrupter himself.
* ''Franchise/TheElderScrolls''
** Most of the [[OurGodsAreDifferent 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. A few stand out, having this as a major part of their M.O. To note:
*** Molag Bal, the Daedric Prince of Domination and Corruption, is the ''embodiment'' of this trope. One of his RedBaron NamesToRunAwayFromVeryFast is "The Corrupter". One of his favorite things is to corrupt a good and noble mortal, then seeing them snap, fall, or break, be it through ColdBloodedTorture, {{Manipulati|veBastard}}on, or flat out MindRape. He especially loves it when mortals do this to ''each other''.
*** Mephala is a Daedric Prince whose sphere is "obscured to mortals", but who is associated with [[ManipulativeBastard manipulation, lies, sex, and secrets]]. She loves to see how she can fray the "web" of human relationships, and takes a particular joy in the betrayal of trust or minor slights tearing entire towns or ''nations'' apart.
*** Sanguine, Daedric Prince of Hedonism and Debauchery, is a case of this being both a significant part of their theme ''and'' downplayed. Tempting mortals to sinful lives is firmly part of his sphere and M.O.... but the sinfulness is ''his'' sins, so he is more likely to push you towards being a lazy glutton than anything outright ''evil'', for all that he doesn't care about consequences.
* 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.]]
** In ''[[VideoGame/Persona2 Persona 2 Innocent Sin]]'', Joker is a wish-granting demonic force who makes the people he helps join his cult, the Masked Circle. The Masked Circle proceed to steal Ideal Energy and spread rumours, rapidly turning Sumaru City into a place where "reality" is just a suggestion. [[spoiler:As it turns out, Joker himself is a victim of a more powerful corrupter: Nyarlathotep, the BigBad, who twisted the kind-hearted Jun Kurosu into a revenge-bent, murderous monster.]]
** ''VideoGame/Persona5'' has [[spoiler:Yaldaboath, who gives both Black Mask and Joker their powers and does his best to make them the enactors of his enslavement of humanity. By the time of the game, Black Mask has become the enforcer of a conspiracy that proves everything Yaldaboath proves about humanity. Joker can break away, but in the second BadEnding he chooses to work with Yaldaboath and act as a KnightTemplar.]]
* ''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. ''VideoGame/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!]]
* ''Franchise/TheLegendOfZelda'':
** [[BigBad Ganondorf]] and {{T|heDragon}}winrova in ''VideoGame/TheLegendOfZeldaOcarinaOfTime'' served as this for the Gerudo tribe. Their cultural [[PlanetOfHats hat]] of being a race of DesertBandits who kidnap Hylians stems largely from their evil influence, with Twinrova in particular using brainwashing magic to keep them in line. The Gerudo characters are less aggressive once Twinrova is defeated, and by the time of ''VideoGame/TheLegendOfZeldaBreathOfTheWild'', which takes place after millennia of lacking any similar evil influence, they've dropped the banditry hat and are much nicer on average.
** [[ArtifactOfDoom Majora's Mask]] from ''VideoGame/TheLegendOfZeldaMajorasMask'' serves as this for the Skull Kid. Originally, the Skull Kid was a mischievous imp who played various pranks on the people of Termina but underneath [[IJustWantToHaveFriends just wanted to have friends]]. Upon stealing the Mask from the Happy Mask Salesman and putting it on, however, the Skull Kid's pranks became increasingly cruel and petty before escalating into full-on region-wide curses, the worst of which is [[ColonyDrop pulling down the Moon to crash into and destroy Termina]].
* [[BigBad The Devil]] can be this in ''VideoGame/{{Cuphead}}'': [[spoiler:Toward the end of the game, he offers a "WeCanRuleTogether" to Cuphead and Mugman after he has forced them to collect the Soul Contracts from the inhabitants of the Inkwell Isles. If the brothers agree to join him and hand over the contracts, it leads to a bad ending where the Devil will turn them into his demonic servants.]]

[[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.
* Larisa from ''Webcomic/SandraAndWoo'' started trying to convince her friends to take the sexier option about whatever they're doing after she made a DealWithTheDevil to become a succubus upon her death.

[[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.]] She also uses tactics from other corrupters such as Jack Slash and Tattletale.
*** [[spoiler: Ultimately, however, Taylor inverts this. The other Undersiders, already anti-villains from the get go, slowly become less and less evil through her influence, until they're more of a heroic vigilante group than a criminal one by the end.]]
** 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.]]
** Of the Endbringers, which include a [[spoiler:monster that can automatically ignite anything within fifty feet of him, a kaiju that can sink islands the size of Newfoundland, a temporal manipulator that can teleport anywhere in the world, a creature that can copy the powers of anything it wants, and a thousand foot tall tower that turns the surrounding landscape into hell on earth,]] the most feared is the Simurgh. She is weaker physically than any other, though her combat skills are still beyond the level of most cape. [[MoreThanMindControl What's terrifying is that she exerts a telepathic force that acts like the proverbial flap of the butterfly's wings, meaning that anyone caught in the effect for too long is not so much driven insane as turned into a living guided missile that only becomes active years after the fact.]]
* 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 ''{{WebAnimation/TOME}}'' does this to Alpha by convincing him that he needs it to keep his friends.

[[folder:Western Animation]]
* Darkseid from ''WesternAnimation/SupermanTheAnimatedSeries'' has elements of this, though he has bigger plans than ''just'' turning Superman to his side.
* Slade from ''WesternAnimation/TeenTitans'' wanted Robin and Terra as apprentices to make them as sadistic and merciless as he is. He has relatively little effect on Robin, only managing to [[HeWhoFightsMonsters make him slightly unhinged in opposition]] and temporarily [[TrappedInVillainy force Robin to do his bidding by taking his friends hostage]]. Terra, [[TheCorruptible who is much more emotional vulnerable]], he [[MoreThanMindControl turns into]] a full-blown supervillain.
* 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'', [[TheDragon 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. This is thanks to being a disciple of [[spoiler: Vaatu]], a powerful dark spirit. Korra learns how to invert this trope, and turns the spirits back to normal.
* 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. Butters his most frequent victim.
** "Crack Baby Athletic Association" has Cartman corrupt the normally morally uptight Kyle to the point that Stan calls Kyle on sounding just like Cartman.
** "Doubling Down" has Cartman corrupt his girlfriend Heidi Turner into eating junk food and become anti-semestic. By the next episode, [[DistaffCounterpart Heidi become another version of Cartman]] thanks to his influence.
* ''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.]]
* Zarm on ''[[WesternAnimation/CaptainPlanetAndThePlaneteers Captain Planet]]'' is this as well. He managed to corrupt four of the Planeteers with power gauntlets called Iron Fists. If it weren't for [[OnlySaneMan Ma-Ti]] [[HeartIsAnAwesomePower who resisted the temptation]] and informed Gaia of this all, the others would have started a nuclear war.
* ''WesternAnimation/YogisGang'': Each VillainOfTheWeek wants to make people have the character flaw they're named after.
* ''WesternAnimation/MiraculousLadybug'': The BigBad, Hawk Moth, has this as his M.O.: he [[TheEmpath is able to sense negative emotions]], and when he finds them, he sends an akuma to that person, promising to grant them powers to right the wrongs done to them or otherwise achieve their goals...so long as they steal [[TheHero Ladybug]] and [[TheLancer Chat Noir]]'s [[TransformationTrinket Miraculouses]] for him, of course.
* ''WesternAnimation/RandyCunninghamNinthGradeNinja'' Has The Sorcerer, an ancient evil entity who lives under the highschool. Whenever someone is experiencing emotional distress he 'stanks' the victim. Then they turn into a giant monster. To stop said created monster you have to destroy their favorite possession at the time.
