* The Panda King and Dmitri were bad guys in previous ''Franchise/SlyCooper'' games, and they get recruited into the Cooper gang in ''VideoGame/Sly3HonorAmongThieves''.
* Miles Edgeworth of the ''VisualNovel/AceAttorney'' series. Edgeworth was raised by his foster father Manfred Von Karma after his real father Gregory Edgeworth was murdered. Miles became obsessed with proving defendants guilty convinced that he needs to be perfect. [[spoiler: Manfred Von Karma turns out to be the murderer and allowing Edgeworth to reconsider his perfectionist record and the Turn is complete in Justice For All.]]
* In ''VideoGame/BaldursGate II: Throne of Bhaal'', you can resurrect [[spoiler:Sarevok, the BigBad from the first game,]] and have him join your team. This is also what happens in the book adaptation. He is still evil, though, but that can be changed (all the way to good) if you make the right choices (he partially falls again, per his epilogue, torn between his old ChaoticEvil self and his new ChaoticGood self in his actions).
* Leliana in ''VideoGame/DragonAgeOrigins''. At the start of the DLC Leliana's Song, she is a thief, a troublemaker, and a murderer. Once she is betrayed by her mentor and lover, and escapes from prison after being tortured, the Chantry takes her in. She becomes the pious bard in the main game, and is the most pure good aligned member on the team.
** Zevran starts off as an assassin who tries to kill the Warden, but depending on the player's choices, can wind up being part of the team.
* Miranda in ''VideoGame/MassEffect2'' starts out as a [[IceQueen cold]] and pragmatic, though [[WellIntentionedExtremist well-meaning]], high-ranking officer in a terrorist organization. Due to Shepard's friendship and influence, (particularly if Paragon), at the end of the game, she has [[DefrostingIceQueen warmed up]] significantly and submits her resignation to the Illusive Man particularly dramatically. By ''VideoGame/MassEffect3'', [[TookALevelInKindness she continues to get better.]]
** Shepard has a similar effect on Jack, who goes from being an AxeCrazy murderer and criminal, to a reformed, genuinely beloved BadassTeacher at Grissom Academy, helping biotic children hone their powers. The ''Citadel DLC'' reveals she also rescued a biotic Varren from an animal shelter and helped it overcome it's past mistreatment, though she apparently doesn't realise the obvious parallels to herself.
** ''VideoGame/MassEffect3'': In two of the game's four endings, this trope is used on [[spoiler:the [[EldritchAbomination Reapers]]. In the Control Ending, [[PlayerCharacter Shepard]] becomes the new leader of the Reapers and promises to rebuild the galaxy and protect its people. In the Synthesis Ending, Shepard triggers a galaxy-wide event that transformers all life into a new form of synthetic-organic life. The Reapers, their original purpose no longer needed, help the galactic races rebuild their homes, sharing the wisdom of the civilizations they harvested in the past.]]
** Paragon Shepard and Nyreen are able to push [[NobleDemon Aria T'Loak]] further into JerkWithAHeartOfGold territory over the course of the ''Omega DLC'', convincing her of better ways to retake the station instead of sacrifice innocent lives. This eventually seems to reach her and at the end, she declares to the masses that "''[[WeAreStrugglingTogether We]]'' [[SubvertedCatchphrase are Omega]]" and appears amazed when she realises they are cheering for her out of [[MachiavelliWasWrong adoration]], not ''fear''.
* In ''VideoGame/ChronoTrigger'', it is possible to talk the villain Magus into joining your party. This is represented less as a change of heart on his end than as a realization that he could achieve his goals [[EnemyMine by working with the heroes]]. By the time the option to have him join comes about, his intent and motivation have been revealed, perhaps making him more of an AntiVillain. On the other hand, when he becomes a party member he appears to become somewhat less of a sociopath.
** In its sequel, ''VideoGame/ChronoCross'', many characters you can eventually play are former bosses. One will even apologize for fighting you earlier in the game.
* ''StreetFighter'' has Sagat, who joins the BigBad's organization after losing to Ryu in the first game, and switches sides in ''VideoGame/StreetFighterAlpha'' ({{retcon}}ning away his status as a villain in ''VideoGame/StreetFighterII''), after realizing that his hatred does nothing but cause him to waste his life. For the entire rest of the series he is more of a WorthyOpponent to Ryu than anything else.
** Also, Cammy, though this is a case of being cured of Bison's MindControl rather than choosing to switch sides. After being cured, she joins the British government in order to bring him down.
* ''VideoGame/StarGladiator'''s [[BigBadassBirdOfPrey Zelkin Fiskekrogen]] had started out as a member of [[BigBad Dr. Edward Bilstein]]'s Fourth Empire, hoping to get revenge against Earth and the humans for a past war that had occurred between them and his home planet of Klondike. However, after fighting against [[TheHero Hayato Kanzaki]] and realizing that not all humans were bad (not to mention having to also realize that Bilstein was far worse than the humans), Zelkin had defected from the Fourth Empire and joined up with Hayato and his friends, determined to set things right while [[TheAtoner atoning]] for his past crimes.
** Aside from Zelkin, Blood Barbarians was also a member of the Fourth Empire as well (albeit when was BrainwashedAndCrazy) and upon having to break free from Bilstein's brainwashing, Blood was also determined to set things right while [[TheAtoner atoning]] for his own past crimes, joining up with Hayato and the rest of the Star Gladiators.
* In ''AdvanceWars: Dual Strike'', Hawke and Lash come to the Allied Nations' aid after being saved by them.
** Tasha and Gage reluctantly join the Rubinelle Army in ''Advance Wars: Days of Ruin'' following [[spoiler:the death of their original commander, Forsythe]], when Will decides not to kill them.
* Alma from the Xbox remake of ''VideoGame/NinjaGaiden'' fights Ryu twice, proving to be a difficult foe both times. However, when Doku, TheDragon, attempts to sacrifice Alma's twin sister Rachel, Alma has a change of heart and throws herself in the way of Doku's blade.
* The good character Faust from ''VideoGame/GuiltyGear X'' onward is incredibly strongly implied to be the villainous character Dr. Baldhead from the first game in the series, after undergoing a Heel Face Turn and taking a new identity.
* The Arbiter in ''VideoGame/{{Halo 2}}'' initially works against the humans to atone himself in the eyes of the Covenant Prophets. When the Prophets betray his species the Elites, and the AI 343 Guilty Spark reveals to him the truth about the Great Journey they want to bring about, namely that it will destroy all life on a galactic scale, he and many other Elites reluctantly side with the humans.
** By the end of the original ''Franchise/{{Halo}}'' trilogy, though, he and his faction have become earnest allies. By the ''VideoGame/{{Halo 4}}'' era, though, he's still fighting against Elite holdouts who ''still'' want to finish the job against humanity.
* ''VideoGame/{{Avernum}}'' 4 has [[spoiler: Rentar-Ihrno]] at the very end of the game, if you make the right dialogue choices.
* [[spoiler:Vivian, one of the Shadow Sirens working for the BigBad]] in ''VideoGame/PaperMarioTheThousandYearDoor'', joins up with {{Mario}} after he's kind to her, er, [[ShesAManInJapan him?]] Of course, one could argue that [[spoiler:Vivian]] was probably GoodAllAlong, or at least was never truly evil.
** Rawk Hawk in the same game (In the Wrestling sense as well)
** [[spoiler:Count Bleck, O'Chunks, Mimi, and Nastasia]] in ''VideoGame/SuperPaperMario''.
** Lakilester in the original ''VideoGame/PaperMario''. When you first meet him he's working for the current chapter's boss, but after a quick battle and a love scene he decides to join you.
* Shiro Amakusa Tokisada from ''VideoGame/SamuraiShodown'' turns into a good spirit in ''Samurai Shodown IV''.
* Magnus Armstrong, one of the antagonists from ''VideoGame/NoOneLivesForever'' is convinced to join the good guys in the sequel, ''No One Lives Forever: A Spy In H.A.R.M.'s Way''.
* Happens all the time in ''VideoGame/SuperRobotWars'', if a character has the least bit of sympathy he will usually do a Heel Face Turn. This is so common that in Original Generation 2 they start {{lampshad|eHanging}}ing it by mentioning that they can expect a recent convert by mentioning all the other people who have done it.
** In ''Destiny'', some could only join if they were convinced [[spoiler:Glacies, Wintos, Margue, Chronicle, Katajina, Roze, Gabil]]. [[EvilChancellor Haman Karn]] of all people can join you if Judau, Char, and Camille rack up an obscene number of kills. It's nearly impossible on your first playthrough, but NewGamePlus all but assures it on later runs.
** While it is very common in OG, the one most notable and most impressive Heel Face Turn would be the one pulled by [[spoiler:Axel Almer]] in OG Gaiden. He doesn't just do normal defection like the others, he shows his Heel Face Turn by [[spoiler:saving a BrainwashedAndCrazy Lamia, who was once thought to be dead and was now about to die again and sticking a metaphorical knife to the team for failing to save her again. So awesome that this scene becomes Axel's definitive CrowningMomentOfAwesome, and also counts as a CrowningMomentOfHeartwarming as he lets go of his hatred for ArtificialHuman in general, and while he doesn't officially join the group, he has forever earned the trust of the heroes as a good guy]].
** ''VideoGame/SuperRobotWars3'' kickstarted this trend by letting ''[[{{Gundam0083}} Anavel Gato]]'' join up if you take a certain route through the game.
** Master Asia in Advance. Given that he was always a WellIntentionedExtremist rather than evil, it's not terribly surprising.
* In ''VideoGame/GuildWars: Nightfall'' General Morgahn is one of Varesh Ossa's generals and quite devoted to his religion, and tolerant of Varesh's. While he appears to be a villain who is not actually evil, just loyal, he actually makes a heel-face-turn and joins the player character, and being required to face Varesh Ossa.
* In ''[[VideoGame/SuperSmashBros Super Smash Bros. Brawl]]'' The Ancient Minister is thought to be the remorseless leader of the Subspace Army, but actually regrets his actions. In truth [[TheManBehindTheMan he isn't the true mastermind]], and thus lost control of of his R.O.B. Squad when Ganondorf stepped in to complete the job of destroying the world with Subspace Bombs. The Ancient Minister then interferes, only to be attacked. It is then his true form is revealed, a R.O.B. From there is only referred to as such and becomes playable.
** In a case of AllThereInTheManual, it is revealed that [[spoiler:Mr. Game & Watch]] is actually a villain, until [[spoiler:Peach gives him her parasol]]. He was apparently not really evil, just incapable of telling the difference between good and evil. Hence, the ease of his turn.
* Sparda in ''VideoGame/DevilMayCry'', who "woke up to justice."
** We've replaced Sparda's unbidden evil with Folger's Crystals. Let's see if he notices...
* Raiden, a cruel, gigantic wrestler from the ''FatalFury'' series of fighting games (and ''Capcom vs. SNK 2''), eventually underwent a ''literal'' Heel Face Turn, taking off his mask and becoming the benevolent Big Bear. The fact that wrestling is fake has become a little ''too'' real for him
** Similarly, ''3 Count Bout'' features one of Raiden's old rivals, the vicious heel Big Bomberder, working a face gimmick by donning a mask to become Gochack Bigbomb. In this case, it isn't a sincere character shift -- it's Big trying to get over with the fanbase (and not doing so hot).
* [[VideoGame/TheWorldEndsWithYou "First you gimme some lame special op and make me snipe my friends, and now you gonna pick on a defenseless Player?! Don't you Reapers have any honor?! Maybe the Composer's down widdat, BUT I AIN'T HIM!"]]
** This one is a HeelFaceRevolvingDoor of sorts, because [[spoiler:Beat starts as a player, becomes a Reaper and a villain, but then performs the Heel Face Turn for the last Game.]]
* After defeating Zidane and friends three times in ''VideoGame/FinalFantasyIX'' and getting a PyrrhicVictory after the third battle upon realizing Garnet's condition, General Beatrix joins your party for a couple of fights and seeks to atone for what she has done.
** An unusual, less extreme example, but it counts. Steiner, even though he's in your party for a greater portion of the game, spends most of his time trying to sabotage the party and deliver Dagger back to the queen. Zidane and the others win his loyalty, eventually.
** Even BigBad Kuja pulls this off before he dies at the end of the game. [[spoiler: Just when Zidane comes to pull off a HeroicBSOD to pick him up just as the Iifa Tree is about to crumble.]]
* [[spoiler:Meliadoul]] in ''VideoGame/FinalFantasyTactics'' (too bad this happens after Orlandu's already joined, however; everything she can do, he can do better). Also, Mediators can use their Invite skill on most enemies (as in, those who aren't plot characters), recruiting them on the spot to your cause (well, with a bit of luck, anyway).
* In ''VideoGame/FinalFantasyVI'', Celes betrays the Empire, and joins the Returners after Locke saves her from torture. Kefka's plan to poison the entire town of Doma crosses her MoralEventHorizon. However, burning down Maranda is simply Empire evil, because she did participate in that.
** Emperor Gestahl pretends to pull one of these creating a Disc One Ending following a DiscOneFinalDungeon, but it's a trap. The party [[TrapIsTheOnlyOption realizes this beforehand]], but they underestimate how far deep they are in.
*** When the above happens, General Leo actually pulls this off, and [[RedemptionEqualsDeath dies for his mutiny]].
* Judge Gabranth in ''VideoGame/FinalFantasyXII'' sides with TheEmpire after believing that his brother, Basch, betrayed them and his men. He even fights the party a few times but near the FinalBattle, [[spoiler: he realizes who the true evil is and assists the party for one battle. Gabranth dies after the war is over and Basch lives on in his name.]]
* ''VideoGame/StarWarsTheOldRepublic'' Elara Dorne, a companion for the Trooper class, use to serve the [[TheEmpire Sith Empire]] before defecting to the Republic.
* Happens in every ''VideoGame/FireEmblem'' game, sometimes more frequently than others. Usually you have to talk to the recruitable enemy with a certain character, but sometimes a former villain will automatically join your side. ''Binding Blade'' had Miledy and Douglas, ''Sword of Flame'' had Heath and Vaida, ''The Sacred Stones'' had Duessel and Amelia, and ''Path of Radiance'' had Jill, Muarim, and Ena. Additionally, Awakening gives you the option of recruiting two former villains, [[spoiler:Gangrel and Aversa.]]
* [[spoiler:Achenar]] in ''[[{{Myst}} Myst IV Revelation]]''
* In the ''VideoGame/{{Persona 2}}'' games, this happens quite a bit, although most of them don't end up joining the party, just being good guys instead of bad guys. [[spoiler:In ''Innocent Sin'', Jun does this after breaking free of Nyarlathotep's influence. As well, Principal Hannya would either die or end up pulling a Heel Face Turn depending on a rumor the protagonist ended up starting with a throwaway dialogue choice. Finally, depending on choices, Anna Yoshizaka would either pull a Heel Face Turn or be replaced by a Shadow counterpart created by Nyarlathotep. In ''Eternal Punishment'', many of the previous villains were forced into Heel Face Turns as part of making a MergedReality; however, Tatsuya Sudou was so deranged and irredeemable that he was instead imprisoned in a mental institution... and Ginji's Heel Face Turn doesn't end up sticking as he is pulled back into essentially the same role he played the first time around.]]
* Judith Mossman in ''VideoGame/{{Half-Life 2}}''. At first she seems to be one of the good guys, but then it is revealed that [[spoiler:she is actually working for Dr. Breen. At the end, she pulls a Heel Face Turn and betrays Breen]].
** Also the Vortigaunts in the series itself can be interpreted as a Heel Face Turn. They go from attacking the player in the first game to worshipping him in the second, though it is because Gordon freed them of the influence of the Nihilanth (but that may not be something the player expects to know right away).
* Klungo in ''[[VideoGame/{{Banjo-Kazooie}} Banjo-Tooie]]'', after he realizes battling with Banjo and Kazooie is making him less and less handsome, and now Mrs. Klungo won't want him anymore!
* Even [[BigBad final bosses]] can get into this. In the DS remake of ''VideoGame/DragonQuestIV'', a 6th chapter is added in which allows you to revive [[spoiler:Rose]], and use ThePowerOfLove to convince Psaro the Manslayer (the aforementioned final boss) to not only stop his plans for world domination/destruction, but also to join your team! His EvilChancellor then takes over the main villain position.
* [[VideoGame/WorldOfWarcraft Knights of the Ebon Blade]].
** More an EnemyMine situation. The Knights have no interest in being heroes, or even being liked (most death knight [=NPCs=], in fact, have quest and gossip text that can be summed up to "Are you useful? If so, good, I've got work for you. If not, piss off."). Their sole motivation for allying with the Argent Crusade is to see the Lich King's head on a pike.
* ''VideoGame/DeusEx'' has Daedalus, an AI programmed by [[AncientConspiracy MJ12]] to hunt down terrorist groups who might threaten their regime. Unfortunately for them, when the AI examined his creators and their actions, he classified them as a terrorist organisation themselves and left to help the player bring them down.
* Saki from the ''{{Oneechanbara}}'' series. Initially the villain, she's revealed to have a pretty good excuse.. and kidnapped by Eva. After Aya rescues her, she stops trying to kill Aya and joins her.
* Axel from ''VideoGame/KingdomHeartsII'', which [[RedemptionEqualsDeath results in him sacrificing himself for Sora.]]
** [[spoiler: Now Lea[[note]] AKA, Axel's Somebody[[/note]] seems to be firmly in Sora's camp, as of DDD. And he seems to have convinced Aeleus[[note]] Lexaeus's Somebody[[/note]] and Ienzo[[note]] Zexion's Somebody[[/note]] to do the same.]]
** Also Cloud, who was technically a villain because he worked for Hades, but he eventually became Sora's ally.
* In ''VideoGame/TheLegendOfDragoon'', the character [[spoiler:Lloyd has his Heel Face Turn moment at the end of the game, just before he dies, giving Dart the Dragon Buster Sword and Divine Dragoon Spirit as proof.]]
* Captain Qwark in the ''VideoGame/RatchetAndClank'' games is a FakeUltimateHero, who periodically sells out to villains or fakes his own death to [[DirtyCoward avoid the shooting]], leaving Ratchet to do the hard yards. Until ''[[GettingCrapPastTheRadar Up Your Arsenal]]'', in which after a HeelRealization he [[spoiler:comes right out of nowhere in a BigDamnHeroes moment to shoot Dr. Nefarious' HumongousMecha]]. Since then he's been Ratchet's ally in all his subsequent appearances. An incompetent ally, though an ally nonetheless.
* Sly, in ''VideoGame/TyTheTasmanianTiger''. Although it is a rather speedy one at that, because he gets beaten ''once'', then is saved on another occasion, and before you know it - he's handing Ty the Doomerang.
* Many of Franchise/{{Sonic|TheHedgehog}}'s allies started off as enemies. These include [[VideoGame/Sonic3AndKnuckles Knuckles]], [[VideoGame/SonicAdventure2 Shadow]], [[VideoGame/SonicRushSeries Blaze]], and [[SonicRiders Jet]].
* [=LeChuck=], of all people, makes a turn after the various Voodoo curses that have been powering him are removed in ''TalesOfMonkeyIsland''. Too bad they're now [[HatePlague infecting the entire Caribbean]]! [[spoiler:[[HeelFaceMole It was just an act]].]]
* Bianca in ''VideoGame/SpyroYearOfTheDragon'', after she realizes [[EvilOverlord The Sorceress']] true plan was [[NotWhatISignedOnFor not what she signed on for]].
* Darth Vader's secret apprentice in ''VideoGame/TheForceUnleashed''. Although the fact that [[spoiler:he just found out that his entire life was based around the fact Vader wasn't using him to help kill the Emperor but, rather, bring those who would speak against the Emperor out into the light]] probably helped a lot.
* Jin Kisaragi from ''VideoGame/BlazBlue'' is an unrepentant [[{{Jerkass}} Class S Asshole]], mostly due to his extreme possessive attitude that he wants to make Ragna his and his only and hates his little sister Saya for that. However, [[spoiler:after turning into Hakumen, he becomes a ''much'' better person who doesn't obsess on his brother and has never mentioned his little sister again; and also became one of the Six Heroes, saving humanity. In fact, Hakumen himself feels ''really'' disgusted at the depravities he caused as Jin, and now all his fights are [[TheAtoner his way to atone for his sins]].]]
** By ''Chronophantasma'', [[spoiler:Relius Clover]]. {{Downplayed|Trope}}: He's still hardly a good guy, but he's working with the heroes because they've stripped him of all his resources and generally put him through a HumiliationConga that he's completely powerless against them, and they're just bringing him along [[spoiler:because Carl needs him to cure Ada]].
* [[spoiler:Byrne]] from ''VideoGame/TheLegendOfZeldaSpiritTracks'', after Anjean, Link and Zelda nurse him back to health, despite everything he did to them. He also received a harsh beating from the guy he helped revive before that.
** In ''[[VideoGame/TheLegendOfZeldaOcarinaOfTime Ocarina of Time]]'', Ingo the spiteful ranch hand later becomes Ganondorf's minion and takes over the ranch. He kicks Talon out and makes people pay to visit. He mysteriously changes his ways after you escape with Epona[[note]]It's implied that Ganondorf [[YouHaveOutlivedYourUsefulness just leaves him[[/note]]]].
** Bomb-Master Cannon from ''[[VideoGame/TheLegendOfZeldaTheWindWaker The Wind Waker]]'' overcharges prices for bombs until [[PirateGirl Tetra's]] [[ThePiratesWhoDontDoAnything Pirate Crew]] steals them. Afterwards, he realizes he could lose his business if he doesn't start selling his bombs at reasonable prices and people resort to stealing, so he sells his bombs at a much more reasonable price.
** Chudley/Malver from ''[[VideoGame/TheLegendOfZeldaTwilightPrincess Twilight Princess]]'' sells items at ridiculously high prices[[note]] The cheapest of which is 10 arrows for 2000 rupees.[[/note]] until Malo buys out his store. After which, he becomes nice and will actually warn Link if he's wasting his money.
** Groose from ''[[VideoGame/TheLegendOfZeldaSkywardSword Skyward Sword]]'' goes from being the jerk of the town who hates Link and constantly bullies him (he even hides Link's Sacred Loftwing so he can't win the big race), to [[spoiler:actually respecting and helping Link near the end of the game]]. For example he builds the "Groosenator", a huge catapult, that helps you in the final [[spoiler:Imprisoned fight]], and he even turns up for a ''BigDamnHeroes'' moment during the [[spoiler: second to final fight agasint Ghirahim when he turns up just in time to save Zelda from falling to her death]].
* King Bulblin in [[http://zelda.wikia.com/wiki/The_Legend_of_Zelda:_Twilight_Princess Twilight Princess]] has one when [[spoiler: during the last of Link's many battles with him, he surrenders as he prefers to follow the stronger side of the war, which he recognizes Link to be.]]
* There are many characters in the ''{{Suikoden}}'' series that join you this way.
** A good example comes from ''VideoGame/SuikodenI'': [[spoiler:All but two of the [[TheDragon Great Generals]] will join you if you opt to show them mercy rather than have them executed. The only two who don't join you are your father, and Ayn, both of whom die at your hands. The Generals who do join you are required for the best ending, in which Gremio is resurrected.]]
* The plot of ''VideoGame/NoMoreHeroes2DesperateStruggle'' is centered around [[VillainProtagonist Travis]] [[AntiHero Touchdown]] gradually turning from a mostly remorseless killing machine into a better person. Although a point can be made that he treads the line between heel and face during the course of the first game and a good portion of the sequel too. Indeed, if he weren't a merciless assassin, this would almost be a case of NeutralNoLonger, due to his attitude during most of the series.
** And then there's one of the ranked assassins, Shinobu, whom Travis spared, who becomes his ally and self-proclaimed apprentice.
* In ''VideoGame/{{Fallout 3}}'', [[spoiler:you can convince President Eden to do this. Though [[TheDragon Colonel Autumn]] has gone against the president and ordered his men to attack you on sight, President Eden counters by having all the Sentry Guns and Security Turrets attack the Soldiers so you can get away easier]].
* [[spoiler:Ruecian]] also makes one in ''VideoGame/ThreadsOfFate'' with Rue's story.[[spoiler:When Valen binds Rue with a doll binding magic Ruecian casts a spell that unleashes Rue's true power, but ends up killed by Valen]] that also counts as HeroicSacrifice.
* Happens in one of the [[MultipleEndings endings]] in ''VideoGame/VanguardBandits''. [[spoiler: NinjaMaid and [[TheMole mole]] Cecilia can betray her contract master and join the hero if one pursues her ending.]]
* The ''Franchise/{{Disgaea}}'' series is full of these kind of characters, though what exactly is a heel face turn and what is instead a FaceHeelTurn can be confusing given disgaea's peculiar brand of BlueAndOrangeMorality. In fact, the first and third Disgaea games are mostly ABOUT the gradual change from villain to anti-hero.
** [[spoiler:Gold Knuckle]] in ''VideoGame/{{Disgaea 3|AbsenceOfJustice}}'' refers to his side change as "turning face!".
* ''VideoGame/RogueSquadron'': Kasan Moore, head of the 128th TIE Interceptor Squadron, defects to the Alliance and provides valuable information. She was from Alderaan, so yeah.
* The Orcish Horde from the ''VideoGame/{{Warcraft}}'' video game series. In the first two games the orcs were AlwaysChaoticEvil, their leaders having sold them into the service of the demonic Burning Legion. But prior to the start of ''Warcraft III'' the orcs, under the guidance of their new warchief Thrall, rediscovered their ancient traditions and the concept of honor, and became a ProudWarriorRaceGuy society.
** This gets escalated even moreso in the MMO ''VideoGame/{{World of Warcraft}}, where the entire Horde not only becomes playable, but is seen as also fighting for similar goals that their enemies the Alliance wants. In fact, the main enemy itself ends up shifting from the Orcs to different people (Old Gods, Deathwing, The Lich King).
* [[spoiler:GLaDOS,]] from ''VideoGame/{{Portal 2}}'', [[spoiler:after being put in a potato and spending the middle to the end of the game with your character. She then becomes very nice to you, then is reset back to disliking you, but is still good enough to just want you gone instead of dead.]]
* The General, from ''VideoGame/{{Mega Man X}}4'', returns to the course of duty after the death of the BigBad, claiming that [[spoiler:Sigma]] had "blinded him to the truth", which may or may not have implied brainwashing. Probably not, considering that at the beginning of the game, he ignored him until the Sky Lagoon's crash forced his hand.
* Uruka, [[spoiler:Kouin and Kyouko]] in ''VisualNovel/EienNoAselia'' all start out on various enemy sides. [[spoiler:The first is kicked out and nursed to health when she loses the ability to fight and the latter two switch after the mind control over Kyouko is broken.]]
* Three of the Fake Evil Kings ([[spoiler: Big Bull, Linda, and Epros]]) in ''VideoGame/{{Okage}}: Shadow King'' end up joining you after being defeated.
* ''VideoGame/SepterraCore''. Araym; Selina [[spoiler: twice]]; Lobo, years before he meets our heroes; in-game mythology ascribes one to Dogo, god of mischief, who helped save the world. [[spoiler: Doskias does one in the ending, but alas, RedemptionEqualsDeath.]]
* The Kuvasz Guild of ''VideoGame/{{Solatorobo}}'', after [[spoiler:Opéra takes over due to the death of Bruno.]]
* In ''VideoGame/SaintsRowTheThird'', assuming [[GreyAndGrayMorality the Saints are the Faces]], Viola [=DeWynter=] pulls a HeelFaceTurn after her sister, Kiki, is killed by their supposed ally.
** Matt Miller, leader of the Deckers in ''The Third'', joins the Saints in ''VideoGame/SaintsRowIV''.
* In the final two routes of ''VideoGame/DuelSaviorDestiny'', [[spoiler:Imnity]] switches sides out of concern for the life of her master, who is not really on the same side as her. Nobody comments on the whole 'she was just trying to end the world' thing either.
* Magolor from ''VideoGame/KirbysReturnToDreamland''. After Kirby and his friends defeat Landia, Magolor steals the Master Crown and goes off to take over the universe. He is defeated, but in the next game, ''Kirby's Dream Collection: Special Edition'', he has reformed and made an amusement park for Kirby.
* ''VideoGame/EpicMickey2ThePowerOfTwo'' uses this trope for all its worth, to the extent where this borders on HeelFaceRevolvingDoor: the Mad Doctor's showed up and offered to help the heroes save the world, but Mickey and Oswald [[HeelFaceDoorSlam find it hard to trust him]]. Turns out, the BigBad was [[spoiler:[[NotMeThisTime Prescott]]]]. [[spoiler:Except [[BrainwashedAndCrazy he wasn't]], and the Mad Doctor was the BigBad [[EvilAllAlong the whole time.]]]] [[spoiler:But if you pick the good ending, the Mad Doctor reforms for real.]]
* Tatjana from ''VideoGame/ArcTheLadTwilightOfTheSpirits''. However, she proves to be an interesting case - in a lot of these cases, the person who does this becomes completely good - but Tatjana still retains her old personality. She never shows remorse for the things she had done to Camilla or other Deimos.
* After being maimed and disfigured by Outworld warriors in ''VideoGame/MortalKombat3'', Kabal renounces the vile Black Dragon organization and becomes a crimefighter at the tournament's end--only to pull a FaceHeelTurn ''[[VideoGame/MortalKombatDeception three games later]]'' when he's unable to shed his thuggish past.
* ''VideoGame/{{Bioforge}}'': Caynan, one of the [[{{Cult}} Mondite]] guards. Unfortunately, it didn't turn out well for him and he was made into a test subject himself.
* Near the climax of ''VideoGame/EmeraldCityConfidential'', [[spoiler:Cutter]], who was working with the BigBad, suddenly has a HeelFaceTurn when he accesses the magical powers of [[MacGuffin the Spirit Rod]] and learns the truth about his past. Specifically, he realizes that the protagonist is [[spoiler:his older sister, who has been trying to find him ever since he went missing as a baby]]. This leads to him working with her to defeat the BigBad.
* Kharad from ''VideoGame/EvilIslands'' used to be a part of Khadaganian Army before defecting to {{La Resistance}}.
* Dr. Morbile, the villain responsible for the events of ''Sacra Terra: Angelic Night'' helped the main character to defeat {{Big Bad}} Lilith in ''Sacra Terra 2: Kiss of Death''.
* In ''VideoGame/BravelyDefault'', Edea starts out as a member of the Eternian Sky Knights and assists them in their pursuit of the Wind Vestal, Agnès Oblige. However, when she witnesses the {{pyromaniac}} BlackMage Ominas Crowe kill his own men when Agnès' party draws near, she becomes thoroughly disgusted with his actions and switches sides right then and there.
* In ''VideoGame/{{Robopon}}'', Bisco saves you from Dr. Zero's collapsing tower at the end of the game.
* In ''VideoGame/DisneyPrincessEnchantedJourney'', after you clear the game, the Bogs remaining in Belle's world have become friendly and play a game of tag.
* In ''VideoGame/TearsToTiara2'', Aemilia does one as soon as [[DefeatMeansFriendship Hamil proves to her there's still hope and he's worthy of her considerable skills by defeating her]]. Of course she had originally been Hamil's father Hasdrubal's ally at court, and is quite fed up with TheEmpire.
** Laelius is ordered by Izebel to massacre a village. He then finds out a separate force is on its way to massacre the village so those villagers would die even if he disobeyed orders. So he does one to save the villagers.
* In ''VideoGame/KirbyTripleDeluxe'', [[spoiler: TheDragon Taranza ends up pulling one, after BigBad Queen Sectonia rewards his loyalty and efforts throughout the game with an ultimately non-lethal YouHaveFailedMe for accidentally kidnapping King Dedede instead of Kirby. She would have won in the end if she had treated him with the respect he deserved, but his defection allows him and King Dedede to pull a BigDamnHeroes right when Kirby needs it most.]]
