History Main / HijackingCthulhu

* In the ''WebVideo/HitlerRants'' parody ''Hitler becomes a Wizard'', the titular character acquires a powerful magic wand. To prove to his generals that magic exists, Hitler even goes as far as to summon Cthulhu, commanding him to lay waste to Berlin.
* During the final arc of ''WebVideo/CriticalRole'''s second campaign, the Mighty Nein believe that [[spoiler:Lucien]]'s plan is to [[spoiler:[[MindHive join the Somnovem]] and become a part of [[EldritchAbomination the city of Cognouza]], ruling together. However, when the time finally comes, Lucien pulls out a FantasticNuke, explains that the Somnovem are too childish and bat-shit insane to be allowed to rule, and blows them up, [[TheStarscream taking the reigns of Cognouza himself]].]]

* ''Series/UltramanGinga S'' has PrecursorVillain Dark Lugiel revived as an unstoppable mindless beast under the control of [[BigBad Excelier]]. [[spoiler:It doesn’t last long, as Lugiel regains his mind and does away with Excelier.]]

*** The Daedric Prince Jyggalag was feared by the other Princes for his growing power, so they came together and trapped him in the form of Sheogorath, the Daedric Prince of [[MadGod Madness]]. Sheogorath would later device a means to pass the mantle of Sheogorath onto the mortal [[VideoGame/TheElderScrollsIVOblivion Champion Of Cyrodiil]], freeing Jyggalag once again.

* The premise of ''Manga/{{Devilman}}'' is that a teenager named Akira hijacks his own DemonicPossession, which gives him full control over the demon Amon's power. His friend Ryu explains that any human can do this if he/she is able to retain their sense of reason.

* Series/KamenRiderExAid has BigBad Masamune do a FusionDance with intended FinalBoss Gamedeus.
* Series/StrangerThings has [[spoiler: [[Main/BigBad Vecna]] take control of a black cloud while banished in the [[Main/AlternateUniverse Upside-Down]], which gives him the ability to control the entire dimension.]]
* Series/UltramanGinga S has PrecursorVillain Dark Lugiel revived as an unstoppable mindless beast under the control of [[BigBad Excelier]]. [[spoiler:It doesn’t last long, as Lugiel regains his mind and does away with Excelier.]]

* In the GrandFinale of ''WesternAnimation/TheOwlHouse'', [[spoiler: [[BigBad Belos]] pulls a DemonicPossession on the Titan's heart, taking all its power for himself. This covers his palace in a decaying filth that takes the form of a twisted version of the Titan, which Belos uses to start destroying the Boiling Isles. Fortunately, the Titan's spirt passes the last of its power onto Luz, [[SuperMode giving her the strength]] to [[DidYouJustPunchOutCthulhu defeat him]].]]

* ''VideoGame/MortalKombat1'': After the main story is over, [[spoiler: Reiko's Arcade ending has General Shao crossing the GodzillaThreshold after defeats by Kitana's army, and he reluctantly sends Reiko on the impossible mission of taming Onaga. While Reiko is almost certain he will die in the attempt, and [[UncertainDoom there's no word from him about the outcome]], General Shao has pre-battlw dialogue that suggests the Dragon King was successfully brought to heel.]]

* Near the end of ''Manga/FullmetalAlchemist'', the central villain Father eventually uses a massive-scale alchemy technique to [[spoiler:absorb Truth -- the setting's God -- into his body. Father was never weak to begin with, but Truth is definitely far more powerful. This backfires on Father when he eventually loses control and gets dragged to hell.]]

* ''Comicbook/DarkCrisis'' sees Pariah, the SupportingProtagonist of ''ComicBook/CrisisOnInfiniteEarths'', bend The Great Darkness, a being [[TheWorfEffect that has]] beaten all of the Angels in heaven(sans Michael and Luficer) while [[EnemyMine bolstered by]] half of the demons in hell and repeatedly {{curbstomp|battle}}ed otherwise dominant DC Comics villains like Darkseid, to his will. Pariah proceeds to use The Great Darkness's might to mind control villains Darkseid, Doomsday, Eclipso, Neron, Nekron, Upside Down Man and, naturally, Empty Hand, [[DemotedToExtra the traditional strongest villain of DC Comics who traditionally precedes The Great Darkness]]. Even the [[HeelFaceTurn Face Turned]] Ares and traditional strongest DC superhero ComicBook/TheSpectre are forced to serve Pariah via The Great Darkness. How does this {{muggle}} dominate what these Earth shattering fighters he now commands couldn't hope to compete with themselves? [[PowerBornOfMadness Sheer insanity]], to the point [[AchievementsInIgnorance Pariah doesn't even realize what he accomplished]] and assumes The Great Darkness is using him as its MouthOfSauron.

Not to be confused with HijackedByGanon or HijackedByCthulhu. Can involve {{Hypno Trinket}}s, {{Soul Jar}}s, [[FreakyFridayFlip body swaps]] or DemonicPossession.

* This has been a running theme with [[VideoGame/SonicTheHedgehog Dr. Eggman]] since ''VideoGame/SonicAdventure''. It wasn't until [[spoiler:''VideoGame/SonicGenerations'']] that he actually succeeded without it [[EvilIsNotAToy backfiring]].
** He managed to do it again in [[spoiler:''VideoGame/SonicForces'']].

* Belphemon Rage Mode is one of the [[NamesToRunAwayFromReallyFast Seven Great Demon Lords]] in the ''Digimon'' Franchise. In ''Anime/DigimonDataSquad'' Kurata's plan was [[spoiler: originally just to control Belphemon, but when his control device was destroyed he just went ahead and transformed himself into data and hijacked Belphemon instead. Up until that point Belphemon was in the relatively safe "Sleep Mode". Being hijacked transformed him into his fully powered Rage Mode, and at the climax of the fight Kurata's face emerged from his chest to show off just who was in control.]]

** It has [[GodSaveUsFromTheQueen Her Imperious Condescension]], who has reproduced the bronzeblood's animal empathy power and mind-controlled the [=GCat=]. [[spoiler:[=GCat=] just so happens to be the alpha universe incarnation of [[PhysicalGod Becquerel]].]]
** Far earlier, Tavros mind-controlled Becquerel and made him teleport a speeding bullet from "towards Jade" to "towards the adult intruder on her lawn". Unfortunately, Troll culture is unfamiliar with the concept of children being raised by their parents, and the "intruder" was actually her Grandpa.
** The Condesce is also able to control [[spoiler:Jade]]. OhCrap.
