* ''Literature/TheSpaceTrilogy'': Weston shows signs of this after being possessed by ''Satan himself'' in ''Perelandra'', although it's not clear whether it's real or an attempt to trick Ransom (always a risk with this sort of thing). Leads to an unplanned "What The Hell, man" moment from readers, as Weston appears to [[DyingAsYourself die as himself]].

* ''Film/{{The Avengers|2012}}'':

* In the often slapstick ''Film/EvilDead2'', this trope's played surprisingly straight. Ash is possessed by the evil and about to kill Annie when he spots the necklace he'd earlier given his girlfriend, still lying on the floor. That memory weakens its control enough that he hesitates and roars in inner turmoil. The camera cuts away as the roar turns into Ash's human screams and sobs, and returns to show that he's himself again.
* In ''Film/GetOut2017'' when Chris talks to Georgina, the Armitage's African-American housekeeper, she tries to have a civil conversation with him, while trying to fight back tears. Later, right as Chris is packing up to head back home from a weekend in Rose's parents' home, [[spoiler: Georgina laves [[CreepySouvenir a box full of pictures of several missing young black people]], including her own picture.]] Which implies that [[spoiler:Grandma Armitage's brain is having a lot trouble keeping "Georgina's" consciousness in [[AndIMustScream "the Sunken]] [[ForcedToWatch Place"]].]]
* ''Film/GIJoeTheRiseOfCobra'': [[spoiler:The Baroness was apparently the only person to ever fight off the nanomites' brainwashing at all.]]
* ''Film/TheHungerGamesMockingjayPart1'': [[spoiler: After being hijacked by the Capitol, Peeta's real self struggles to show through.]]
-->[[spoiler:"How do you think this will end? What will be left? No one is safe. Not in the Capitol. Not in the districts. And you... In Thirteen... Dead by morning!"]]

* In Jeramey Kraatz's ''Literature/TheCloakSociety'', [[spoiler:Lone Star]] discusses how they learned to resist telepaths; when asking how, then, can Shade control [[spoiler:Dr. Photon]], he explains that he is resisting, as witness she has to be physically present to keep him in line.
* In ''Literature/TheDarkElfTrilogy'', Drizzt's father is [[spoiler: sacrificed to Lolth, and turned into a super-zombie to hunt down Drizzt. His memories were deleted, resulting in sub-par swordsmanship, so more were returned. Drizzt and his father fought over a pit of acid. Drizzt's father ended up breaking through the zombification just long enough to make his corpse fall into the acid, permanently re-killing it.]]
* In the ''Literature/{{Discworld}}'' novel ''A Hat Full of Sky'', Tiffany Aching fights this battle against the possessing Hiver, but is unable to prevent it from insulting a friend, humiliating a supercilious shop assistant and, more importantly, murdering a teaching witch (luckily, said witch has two bodies).

* ''Literature/AFireUponTheDeep'' by Creator/VernorVinge plays with this with Flenser/Tyrathect battling for control and showing various outward signs of the battle. In a subversion of the usual application of this trope, EvilOverlord Flenser is the "original" personality, that tries to break to the surface and overcome "possession" by Tyrathect fragments. [[spoiler:While he thinks for a moment that he succeeded, actually they merge in the end.]]
* Subverted in ''Literature/{{Grunts}}'' by Mary Gentle[[spoiler:: The BigBad gives the Messiah -- whose body she has possessed -- one last brief look around before obliterating her]].

** This trope could also apply to Harry's fear in the fifth book that he had physically been attacking people. Similarly, [[spoiler: Ginny]] really ''was'' being controlled by Riddle in the 2nd book.

* ''[[Literature/TheMazeRunner The Maze Runner Trilogy]]'':

* In Creator/AlanGarner's fantasy novel ''Literature/TheMoonOfGomrath'', the heroine Susan is possessed by the Brollochan, an age-old Celtic spirit of evil, and has to fight to regain possession of her own body.
* In Creator/CJCherryh's ''Literature/MorgaineCycle'', the villain of the original trilogy used a [[CoolGate time/space Gate]] to [[GrandTheftMe steal]] the body of the viewpoint character's cousin. In the third book, it's revealed that millennia of body-theft has eroded his soul to the point where his latest victim can take back control. "If anything of your cousin has influence ... then he may yet defeat the man who killed him." [[spoiler: He does; the epilogue [[BittersweetEnding commemorates his death from old age]].]] The fourth book includes '''arguments''' within the mind of another victim who retains much of both personalities. He's quite shocked to discover that the evil lord he'd battled is a much more reasonable person than he'd thought (despite taking over his body).

* In the ''Literature/WarriorCats'' book ''The Place of No Stars'', [[spoiler:Ashfur [[BrainWashedAndCrazy mind-controls]] Squirrelflight's mate Bramblestar into attacking her. As he does so, Bramblestar tries his best to resist Ashfur; at one point, Ashfur even ''shouts' at Bramblestar out of frustration of how hard it is to control him.]]
* ''Literature/TheWheelOfTime'': Rand al'Thor. They don't call him the Dragon Reborn because just because he's a phenomenally powerful channeller and a stone-cold bastard. He actually gets Lews Therin Telamon, the Lord of Morning, in his head along for the ride! Only, nobody told Lews Therin. He thinks he just blacked out and someone is inside ''his'' head. Independent of that, Lews Therin is batshit crazy and the Dragon Reborn will be soon, too, with Rand staving this off by promising Lews Therin that they will both die at Tar'mon Gaidon, the Last Battle. As a result, he gains Lews Therin's reluctant assistance and advice, though this is leavened by the fact that Lews Therin is, again, ''completely insane''. [[spoiler: Eventually, as he's on the cusp of a SuicidalCosmicTemperTantrum that would have blown up the world, Lews Therin is suddenly lucid for a moment and muses that perhaps they are born again so they can try again - so that this time, they can get it right. Cue EpiphanyTherapy and a SplitPersonalityMerge that leaves Rand with flavourings of Lews Therin's personality, a much calmer nature, and all the latter's vast knowledge]].

** In ''The Death Cure'', [[spoiler:Newt is infected with [[HatePlague the Flare]]; due to having been mentally overstimulated by all of the tests over the preceding few years, the disease’s progression speeds up to the point where he’s teetering on the edge of the Gone by five days. While he tries to fight the symptoms (aggression, paranoia, sudden violence) as the disease progresses in an effort to keep his friends safe, he eventually succumbs, and Thomas has to MercyKill him]].

* An early [[UsefulNotes/TheSilverAgeOfComicBooks Silver Age]] example is when ComicBook/CaptainAmerica was treated with a mind control drug by the Red Skull and ordered to join a German paratrooper raid to assassinate Gen. UsefulNotes/DwightDEisenhower. They get as far as invading the General's office and Cap takes aim at him as ordered. At that point, Cap's subconsciousness rebels and keeps him from moving, much less pulling the trigger and the mind controlled superhero is at a loss to understand why. The German commando leader tries to manipulate Cap's hand to fire, but that physical force allows Cap's mind to break free of the drug and fight all the commandoes in Eisenhower's defense while the general calls security.

* Marvel UK's cyborg [[ComicBook/DeathMetalMarvelComics Death Metal]] is a MindHive in a body that's made from a tainted magical metal, leaving him subject to ArtifactDomination.

[[spoiler:Which is exactly why Argon's manipulative father arranged for him to be killed and assimilated]].

** ''ComicBook/WonderWoman1987'': Deimos finds out quickly that taking possession of ComicBook/TheJoker might not have been the best idea he'd ever had, and Franchise/WonderWoman and ComicBook/{{Batman}}'s plan to defeat Deimos is centered on the fact that they know the Joker is going to win the fight for control of his own mind once they realize he's fighting the god instead of in cahoots with him.
