History DemonicPossession / VideoGames

* ''VideoGame/DawnOfWar II'': If [[spoiler:Jonah]] is the traitor in ''Chaos Rising'', this is the reason. [[spoiler:He suffered severe mental scars when he fought the Tyranid Hive Mind, and between that and Kyras betraying him by handing Chaos the access rites to his psychic hood, he is possessed by a daemon, though he manages to [[FightingFromTheInside keep it corralled]] long enough for his battle-brothers to fight back.]]

* The Phoenix arc of ''Franchise/AceAttorney'' features spirit channeling, in which a spirit medium allows herself to be possessed by a dead spirit. It's not hazardous in itself, but possession by a vengeful spirit can force the medium to do violent acts. [[spoiler: And Dahlia Hawthorne's as vengeful as they get.]]
* The Taken in ''VideoGame/AlanWake'' are an army of this, possessed permanently by the Darkness. The Darkness can do a more limited version of this, which was used on [[spoiler: Rose, Alan, Thomas Zane, and Cynthia Weaver.]]

* [[TearJerker Tragically done]] AND [[SugarWiki/MomentOfAwesome gloriously inverted]] in ''VideoGame/ArcTheLad II'': [[spoiler: the BigBad manages to take control of Kukuru and "absorb" her, only to discover that Arc's girlfriend's soul is stronger than his own: she promptly inverts the demonic possession and gives Arc the time to seal him again]]
* [[spoiler: Mithra]] from ''VideoGame/AsurasWrath'' gets possessed for a short time by [[spoiler: Chakravartin in order for him to use her power to regain his true form.]]

* Survival horror game ''VideoGame/CampSunshine'' has [[spoiler: Isaac Illerman, the serial slasher who turns out to have been possessed all along]].

* Once summoned to a particular location, demons in ''VideoGame/ConradStevensonsParanormalPI'' can exert their influence over vulnerable individuals and eventually take full control of them for certain periods of time, after which the individual is often unable to recall the event. While the [[OccultDetective player character]] can't fall prey to this ability on account of the comparatively brief amount of time he spends at each location and his [[NervesOfSteel collected]] nature, stories of individuals suddenly acting more aggressively without explanation, especially if they've gone on to commit massacres, can be compelling evidence of demonic presence in conjunction with other paranormal indicators.

* This is a big part of ''Morella'', the twelfth game in the ''VideoGame/DarkTales'' series. Not only are you and Literature/CAugusteDupin trying desperately to rescue a little girl who's been possessed, but [[spoiler:in the process of doing so, you inadvertently become possessed yourself and spend much of the rest of the game FightingFromTheInside.]]

* In ''VideoGame/DevilSurvivor'', Amane is possessed by [[spoiler: not only Remiel, an angel, but Jezebel, a demon.]]

* In ''VideoGame/TearsToTiara2'', Metatronius possesses [[BigBad Abraxas]] to break his seal and resume heaven's original plan to turn humans into helpless praying idiots. Melqart, the AxCrazy Godofwar also came close to possessing [[TheHero Hamil]].
* In ''[[RogueLike TOME]]'', Spirits can possess any body on the ground; effectively raising them BackFromTheDead. GameplayAndStorySegregation means there is little difference between a possessed corpse and its original. For clever individuals with a Wish spell, one can create a Familiar Spirit and have it possess ''anything'' with a corpse; making that your familiar. [[Literature/TheLordOfTheRings Gandalf]], the {{Superboss}}, ''anything that you killed with a body that you preserved.'' One of the classes is "Symbiote" which means you can fuse yourself with any Familiar that doesn't move. One of the Bonus Bosses is a Mold...
* In ''VideoGame/{{Unepic}}'' Daniel ends up in a medieval fantasy universe and is promptly possessed by an evil spirit -- which is unable to take over his body due to him having no faith.
* In ''VideoGame/UntilDawn'', [[spoiler: people who commit cannibalism on the mountain are possessed by the spirit of the {{Wendigo}}, and transformed into monsters. When Hannah is forced to eat her dead twin sister to attempt to survive lost in a mine, she is possessed by [[BigBad Makkapitew]], the most powerful Wendigo ever.]]
* All of Ethan's family members in ''VideoGame/TheVanishingOfEthanCarter'' are befallen by a malevolent spirit known as the Sleeper which makes them want to kill Ethan.

* Happens a few times in the ''VideoGame/WildArms'' series.

* In ''VideoGame/PaperMarioTheThousandYearDoor'', Grodus [[spoiler: summons the Shadow Queen, who then possesses Princess Peach. Fortunately, Mario arrived just in time]].
** [[spoiler: Just in time to be forced to beat up his ImpliedLoveInterest, that is]].
** This happens a lot in the Mario [=RPG=]s. [[spoiler: Especially to Bowser, who gets possessed three times so far for the final battle. First by Cackletta in ''[[VideoGame/MarioAndLuigiSuperstarSaga Mario & Luigi: Superstar Saga]]'', then the Elder Princess Shroob in ''[[VideoGame/MarioAndLuigiPartnersInTime Partners In Time]]'', and then the black paint in ''VideoGame/PaperMarioColorSplash''. Even Luigi becomes a victim of this in ''VideoGame/SuperPaperMario'', fusing with the Chaos Heart and Dimentio to form the FinalBoss.]]
** Antasma does this to a few people in ''VideoGame/MarioAndLuigiDreamTeam'', possessing Broque Monsieur in the intro and Bowser in a battle part way through the game.
** Not even sports games are immune: ''VideoGame/MarioTennisAces'' sees Luigi, Wario and Waluigi all get possessed by the evil racket Lucien.

** ''VideoGame/KirbysReturnToDreamLand'': The Master Crown. [[spoiler:It may look like it only grants its wearer limitless power, but when it does so, it corrupts their heart with darkness and turns them into [[OmnicidalManiac Omnicidal Maniacs]] hellbent on destroying everything. This is what happens to Magolor when the crown corrupts him after letting all of the power go to his head. Magolor Soul is even worse considering that he's described as an EmptyShell for the crown to control. Hammering this point home is Magolor Soul's True Arena boss fight in ''Deluxe,'' where he faintly be heard crying for help after the ThemeMusicPowerUp kicks in.]]

* In ''VideoGames/{{DONTLOOKAWAY}}'', the Entity is implied to be an intangible demonic force that is possessing the [[MurderousMannequin mannequins]].

* Once summoned to a particular location, demons in ''VideoGame/ConradStevensonsParanormalPI'' can exert their influence over vulnerable individuals and eventually take full control of them for certain periods of time, after which the individual is often unable to recall the event. While the [[OccultDetective player character]] can't fall prey to this ability on account of the comparatively brief amount fo time he spends at eavh location and his [[NervesOfSteel collected]] nature, stories of individuals suddenly acting more aggressively without explanation, especially if they've gone on to commit massacres, can be compelling evidence of demonic presence in conjunction with other paranormal indicators.

Hammering this point home is Magolor Soul's True Arena boss fight in ''Deluxe,'' where he faintly be heard crying for help after the ThemeMusicPowerUp kicks in.]]

** In ''[[VideoGame/KingdomHeartsBirthBySleep Birth By Sleep]]'' it's revealed that [[spoiler: that Xehanort, the BigBad from the previous games, is actually a Keyblade master named Terra, who, like Riku, gave into the darkness in his desire for revenge, thus allowing the original Xehanort, an old Keyblade master, to possess his body, and become the Xehanort that we all [[PerverseSexualLust know and love]].]]

** There's also ''VideoGame/KirbyAndTheForgottenLand'' with [[spoiler:Fecto Forgo, who uses mind control to control the members of the Beast Pack and drive them insane (King Dedede acting like a enraged boar as Forgo Dedede). This is most prominent with Leongar, whom Soul Forgo completely possesses in the post-game under the new name "Forgo Leon".
