History FaceHeelTurn / VideoGames

* In ''Call of Duty: Modern Warfare 2'', [[spoiler: Gen. Shepherd has one near the end of the game and kills Roach and Ghost.]]

* Kain from ''VideoGame/FinalFantasyIV'', partly because of brainwashing, but also partly because of his envy for his best friends Cecil, who was the boyfriend of the girl he had a crush on.

* The VideoGame/MegaManZero series gives us Elpizo in the second game.

* Subverted in ''VideoGame/PokemonMysteryDungeonExplorers'', when your partner seemingly sides with Darkrai, only for the hero to immediately deduce that they've been trapped in a nightmare due to knowing they'd never give up so easily, and snap themselves back to reality by attacking the latter of the two.

* Both [[spoiler:Dr Sorkin and Yoder]] turned on the team for their selfishness in episode 4 of VideoGame/JurassicParkTheGame.

* In ''VideoGame/FinalFantasyTacticsA2'' there's a pair of paladins who were known for the superb swordsmanship and skills in combat. However, one of the paladins, Frimelda, is superior to her other paladin friend, Luc Sardac, in battle skills. Luc Sardac tries his best to match his skills with Frimelda's, but he could never get any better. Rather than accepting his limitations, Luc Sardac decides to kill Frimelda so that he would be the superior paladin. It didn't stick due to Frimelda's sheer force of will keeping her alive, but as a zombie. When the zombified Frimelda and your party confront Luc Sardac over what happened, he decides to attack you.

* The Wanderer from ''VideoGame/DiabloII'' who is heavily implied to be the protagonist from the first game. In fact, Creator/{{Blizzard|Entertainment}} (who made ''Warcraft'', ''StarCraft'' and ''Diablo'') is so fond of this trope that it has become known as the Blizzard Principle when in a video game you have to take on lasts game's protagonist (or other good guy) who have gone mad.

* The [[BigBad villain]] from the very first ''[[VideoGame/FinalFantasyI Final Fantasy]]'', Garland's {{backstory}} states that he was once a famous hero. [[FaceHeelTurn That all changed]] when he kidnapped [[EverythingsBetterWithPrincesses the princess of Cornelia]] in a bid to take over the kingdom.

* ''VideoGame/KingdomHearts''
** Riku was, unknown to his best friend Sora, gradually making a descent into darkness, desperate to [[IDidWhatIHadToDo save Kairi through whatever means possible]]. He ends up pulling a complete 180 with a return to the good side and a MyGodWhatHaveIDone moment where he realizes just how far he's fallen, spending a majority of screentime until ''Kingdom Hearts 3D'' trying to earn his redemption.

* In ''VideoGame/StarCraft'' you have Sarah Kerrigan, who go from being the protagonist's girlfriend to becoming the Zerg Queen of Blades, then you have Arcturus Mengsk who seems like a nice guy then turn out to be a genocidal dictator. Followed by Samir Duran who first joins up with the United Earth Directorate to bring down Arcturus Mengsk, and then betrays them to the Zerg, then he betrays the Zerg to Amon]].
** Kerrigan is less case of a FaceHeelTurn than forcible corruption by the Zerg, making her BrainwashedAndCrazy. This is supported by the HeelFaceTurn she goes through after being cleansed of the Zerg corruption in ''VideoGame/StarCraftII''... although she is still something of a WellIntentionedExtremist. Duran is actually a subversion as it is revealed that [[spoiler: he was EvilAllAlong.]]
* The Wanderer from ''VideoGame/DiabloII'' who is heavily implied to be the protagonist from the first game. In fact Blizzard (who made Warcraft, StarCraft and Diablo) is so fond of this trope that it has become known as the Blizzard Principle when in a video game you have to take on lasts game's protagonist (or other good guy) who have gone mad.

*** On the Azure Moon route, if not recruited in Part I, [[spoiler:Hanneman and Manuela defect to the Empire during the five-year timeskip and are fought in Dimitri's paralogue, The Silver Maiden]].

** In ''VideoGame/FireEmblemThreeHouses'', midway through the Black Eagles route, [[spoiler:Edelgard and Hubert betray you when the former is revealed to be the Flame Emperor who has been launching attacks on the Church throughout all of Part I, and you outright fight Edelgard as a boss after the reveal. You can join their crusade after defeating her, but doing so causes Flayn to turn against you.]]

* [[spoiler:Aribeth de Tylmarande]] of VideoGame/NeverwinterNights does this. [[spoiler:Bastila from ''KnightsOfTheOldRepublic'']] was [[spoiler:Aribeth]] dropped into an alternate setting and given a more active role in the story.

* ''VideoGame/TheWorldIsYourWeapon'': In the secret ending path, [[spoiler:Weaco picks up all the humans on the island and adds them to her inventory as weapons, and refuses to sell or discard them to restore them to their rightful place]].

* In ''VideoGame/{{MOTHER}} 3'', [[spoiler:Claus is brainwashed by Porky and becomes the Masked Man (also the FinalBoss)]].

* ''VideoGame/KnightsOfTheOldRepublic II'':

* [[spoiler: Bastila]] in ''VideoGame/KnightsOfTheOldRepublic''. In the backstory, we also learn that [[PredecessorVillain Darth Revan]] and [[BigBad Darth Malak]] were Jedi war heroes who saved the Republic from a previous invasion before they turned to the dark side and invaded the Republic themselves.
* Arguably, both [[spoiler: Kreia]] and [[spoiler: Atris]] in ''VideoGame/KnightsOfTheOldRepublic II''. Yes, both were already Grade-A bitchy, but neither was definitively evil until the end of the game.
** Can also happen to anyone you have a high influence with in the sequel, if you're [[KarmaMeter going]] [[VideogameCrueltyPotential dark]].
** The Jedi Masters could easily be interpreted as this.

*** To be fair though, it's heavilly implied that Jin is doing this just so that he can kill off his own bloodline by any means necessary, bringing both Kazuya and Heihachi out for him to fight up front. Though [[spoiler:no one is aware of Lars, Heihachi's illegitimate son.]] Though quite villainous and menacing still, this does make Jin more of an AntiHero, or an AntiVillain maybe.

** In MortalKombat11, Frost, once Sub-Zero's most promising pupil, has joined Kronika, Sektor and the Cyber Lin Kuei, turning Sub-Zero's ninjas into Cyber Lin Kuei and seeking to destroy the Shirai Ryu and carry out Kronika's evil will. Sub-Zero is saddened and disappointed at [[APupilOfMineUntilHeTurnedToEvil what his former student has become]].

** ''VideoGame/MortalKombatX'' sees several good characters go heel. [[spoiler:Kung Lao, Kitana, Smoke, Kabal, Stryker, Nightwolf, and Liu Kang end up staying as revenants, while Scorpion does a HeelFaceDoorSlam. Raiden himself goes rogue, after his HeroicSacrifice at the end of ''MKX''.]]

* In ''VideoGame/StarCraft'' you have Sarah Kerrigan, who go from being the protagonist's girlfriend to becoming the Zerg Queen of Blades, then you have Arcturus Mengsk who seems like a nice guy then turn out to be a genocidal dictator. Followed by Samir Duran who first joins up with the United Earth Directorate to bring down Arcturus Mengsk, and then betrays them to the Zerg, then he betrays the Zerg to [[BiggerBad Amon]].

* Not to mention the Wanderer from ''VideoGame/DiabloII'' who is heavily implied to be the protagonist from the first game. In fact Blizzard (who made Warcraft, StarCraft and Diablo) is so fond of this trope that it has become known as the Blizzard Principle when in a video game you have to take on lasts game's protagonist (or other good guy) who have gone mad.

Followed by Samir Duran who first joins up with the United Earth Directory to bring down Arcturus Mengsk, and then betrays them to the Zerg, then he betrays the Zerg to some unknown higher power.

* In ''VideoGame/KidIcarusUprising'', [[spoiler: Pyrron]] is just your everyday, LargeHam, [[KillItWithFire fire happy]] [[spoiler: sun god]]. He's just about the only guy who knows what the [[spoiler: Auron]] are all about, and while he's mostly an idiot, he certainly knows how to make them hurt. [[spoiler: Until you reach the Auron brain, and in the middle of the boss fight he dives right in and completely takes over the alien hive mind.]]

* The player character and his FiveManBand in ''Mechwarrior 4: Vengeance'' becomes the FiveBadBand in the ''Black Knight'' expansion.

* [[spoiler: Bastila]] in ''VideoGame/KnightsOfTheOldRepublic''. In backstory, we also learn that [[PredecessorVillain Darth Revan]] and [[BigBad Darth Malak]] were Jedi war heroes who saved the Republic from a previous invasion before they turned to the dark side and invaded the Republic themselves.

* Riku from ''VideoGame/KingdomHearts'' was, unknown to his best friend Sora, gradually making the FaceHeelTurn, desperate to [[IDidWhatIHadToDo save Kairi through whatever means possible]]. He ends up going a similar way as Kain from ''VideoGame/FinalFantasyIV'', complete with a return to the good side and a MyGodWhatHaveIDone.

This is supported by the {{Heel Face Turn}} she goes through after being cleansed of the Zerg corruption in ''VideoGame/StarcraftII''... although she is still something of a {{Well Intentioned Extremist}}. Duran is actually a subversion as it is revealed that [[spoiler: he was {{Evil All Along}} and a servant of the series' {{Bigger Bad}}.]]

* In ''MOTHER 3'', [[spoiler:Claus is brainwashed by Porky and becomes the Masked Man (also the FinalBoss)]].

* This isn't a trope that Starscream in ''VideoGame/TransformersWarForCybertron'' would go down as he's more related to TheStarScream, but he starts out as an Autobot Scientist at the beginning of the Decepticon campaign. After Megatron bests his defenses, Starscream switches from the Autobots to the Decepticons. He later pulls his own trope off.

** In ''VideoGame/ShinMegamiTenseiStrangeJourney'', after Jimenez [[spoiler:fuses with Bugaboo]] and Zelenin [[spoiler:transforms into an angel]], their loyalty to the mission becomes increasingly shaky. At the conclusion of Sector Grus, both of them formally desert the Red Sprite for the demons and Mastema, respectively. A short while later, the protagonist can join them.
