* ''WesternAnimation/RickAndMorty'': Jerry openly sees his father in law [[Characters/RickAndMortyRickSanchez Rick Sanchez]] as a corrupting influence on not only his children but also Beth. Morty ends up doing horrible things in his adventures with Rick, including several acts of murder which have traumatized him emotionally and psychically, and Rick's constant humiliation and undermining of him makes Morty and even Summer into darker people. Likewise, Evil Morty more or less implies that he was the product of Rick's abuse and treatment.

* Darkseid from ''WesternAnimation/SupermanTheAnimatedSeries'' has elements of this, though he has bigger plans than ''just'' turning Superman to his side.

* ''Film/GodzillaKingOfTheMonsters2019'': [[Characters/MonsterVerseAlanJonah Alan Jonah]] plays this role to Emma Russell, nudging her to do evil in the name of the so-called greater good.

* ''WesternAnimation/{{Amphibia}}'': [[Characters/AmphibiaTheCore The Core]], [[spoiler:or more specifically its latest assimilee King Aldrich]], is responsible for molding King Andrias into the person he's become, and more than that he ultimately tries to tempt Marcy into becoming permanently absorbed by the Core using a LotusEaterMachine.

*** In ''Super'', he is this to Tagoma. In the film, he merely killed Tagoma by throwing him out into space. In ''Super'', he tortures him by shooting him in the kneecaps, then has him assigned as his sparring partner during his four month training regiment. After four months of brutal training, Tagoma's sanity is shot to hell and he becomes every bit as cold and ruthless as Frieza, so much so that he ruthlessly kills Shishami in an attempt to kill Gohan. Frieza is so impressed by his ruthless cunning that he offers Tagoma his own planet if he kills the Z fighters.

* ''Manga/SoulEater'' has Asura, the Kishin who irradiates Madness, and his Clowns (being Madness given physical forms), as Madness is a force of chaos that affects humans and other supernatural beings and thus threatens the balance of the world; as well as Medusa for Crona, ''her own child'' who she treats as nothing more than a lab rat for her experiments with Black Blood, and raised them as a killer in order to hunt innocent souls in a bid to create the ultimate Kishin.

** 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.

* ''Fanfic/JauneArcLordOfHunger'': Darth Nihilus became a master of this trope after his soul was trapped in his mask. Over the course of several months, he influences Jaune into drawing from the Dark Side and encourages him to embrace his worst impulses. More than a century ago, he was also responsible for corrupting [[WarriorMonk Petros Krizoz]] and turning his sect of the church into a death cult worshipping himself. He also tried to be this to Jaune's ancestor Alix, but Alix was able to resist him through his HeroicWillpower.

* ''Fanfic/AllForLuz'': All for One is this to Luz throughout all the horrible situations she's in, with some results to his liking. This includes getting her to steal more Quirks, GainingTheWillToKill, and having some resentment towards her mother. He's essential trying to be the Palpatine to her Anakin Skywalker.

* ''Fanfic/CodePrime'': Megatron, as always. [[spoiler: He's deliberately trying to push Suzaku down a darker path, mostly for his own amusement]].

* ''Film/{{Pearl}}'' (2022): Since this film is the prequel to ''Film/{{X|2022}}'', where [[spoiler:Howard]] is shown to be in cahoots with the murderous [[spoiler:Pearl]], yet here [[spoiler:he]] is repeatedly talked about as a hard-working and patriotic [[spoiler:young man]] who does not mind [[spoiler:working on a farm and jumping at the call to serve in [[UsefulNotes/WorldWarII WW2]], despite his]] high socioeconomic status, thereby presuming a person of good ethics, it is safe to say that [[spoiler:she]] has got [[spoiler:him]] very agreeable to [[spoiler:her]] lifestyle between the times not covered by ''Pearl'' and ''X''.

* Moira MacTaggart of the ''ComicBook/XMen'' who's goal was to break Charles Xavier of his idealism, getting him to a point he was willing to do all sorts of shady things out of desperation to avoid yet ''another'' mutant genocide [[YouAreWhatYouHate which he obviously regrets]]. Even before that point though her plans involved a lot of manipulation and secret keeping which would have only exacerbated Xavier's own manipulative and secretive tendencies, something that would carry over to affect more than just his work with her, which without Moira's influence he would have kept more in check and/or worked to overcome. It also happens to provide a in-universe explaination for the {{Flanderization}} his character has undergone with post-Claremont writers as even his pre-Claremont characterisation was not ''that'' much of a jerk.

Even before that point though her plans involved a lot of manipulation and secret keeping which are two of Xavier's worst tendencies and exacerbating would have affected more than just his work with her.

-->'''Professor X''': There's no denying what you have done, Moira. You shaped us into this... you made us into this... we are the perfect tools for an imperfect age. You should celebrate what you have done for you have done it well. But now it is time for you to step aside and let us do the good work for which we were created.

* ''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 ([[spoiler:what with being a former [[AristocratsAreEvil World Noble]] and all]]), 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.
