History TheMole / VideoGames

* In ''VideoGame/PerfectDark Zero'', Chandra is secretly working for Zhang Li, which she reveals after killing Dr. Carroll. She herself is sacrificed by Zhang at the end of the game to gain her life force.

* ''VideoGame/WinBack: Covert Operations'': Your squad leader, who happens to be the brother of the BigBad that was offed by TheDragon [[TheStarscream turned traitor himself]]. Before the penultimate battle, he reveals that he sabotaged the helicopter, causing it to explode and faking his death (NoOneCouldSurviveThat), and that he killed the two teammates you found StuffedIntoTheFridge.

** There's more than that, however. One Mages Guild quest requires you to root out a potential Telvanni spy; [[spoiler:It's the Archmages personal assistant]]. A House Hlaalu quest has you delivering new orders to their spy watching their rivals House Redoran, [[spoiler:the upper-class tailor in Ald'ruhn, the Redoran capital]]. Though one doesn't formally come up in the Thieves Guild questline, you can find a few Thieves Guild members deep undercover at the Camonna Tong HQ, the Dren Plantation.

Before the penultimate battle, he reveals that he sabotaged the helicopter, causing it to explode and faking his death (NoOneCouldSurviveThat), and that he killed the two teammates you found StuffedIntoTheFridge.

** ''X8'' has [[spoiler:Lumine]] as this as well as the [[spoiler:BigBad]]. Even the original [[TheMole Maverick Mole]], Sigma, [[spoiler:is demoted to being a mere minion of Lumine]].

** There's also Ricardo from ''VideoGame/TalesOfInnocence''. Man, the Tales series just loves this trope.

* In Persona3, [[spoiler:Ikutsuki, who was TheMentor to the S.E.E.S. team, turns out to have been pulling their strings. Defeating the Bosses of each month, which he claimed would end the Dark Hour, instead brought about the end of the world as they knew it.]]

* In ''VideoGame/Persona3'', [[spoiler:Ikutsuki, who was TheMentor to the S.E.E.S. team, turns out to have been pulling their strings. Defeating the Bosses of each month, which he claimed would end the Dark Hour, instead brought about the end of the world as they knew it.]]

* In ''[[Franchise/ProfessorLayton Professor Layton and the Azran Legacies]]'', [[spoiler: ''Emmy herself'' is revealed to have been a mole for Targent all along. '''OUCH''.]]

* ''VideoGame/FrontMission'' loves this trope. Most of the [[spoiler:PMO]] are ignorant of what goes on in [[spoiler:Sakata Industries]], being on the outside looking in. But there are those [[The Mole Moles]] who are well aware of such things, including [[spoiler:President Koichi Sakata himself!]]

* [[MissionControl Angel]] in ''VideoGame/{{Borderlands 2}}'' is revealed to be a spy for [[MegaCorp Hyperion]] when the player plugs Wilhelm's AI core into Sanctuary's defense systems and she uses it to lower the shields. She spends the next few chapters trying to apologize and convince the player that she's still their ally.

* The plot of the ''VideoGame/SamAndMaxFreelancePolice'' episode "The Mole, The Mob and the Meatball" was for Sam and Max to find a mole who infiltrated [[PunnyName Ted E. Bear's]] [[LegitimateBusinessmensSocialClub Mafia Free Playland and Casino.]] [[spoiler:Turns out the mole was an ''actual'' mole and he switched sides as the new Don]].

* In ''VideoGame/BaldursGateII'' there is [[spoiler:Yoshimo. He is forced to spy on you due to a curse Irenicus put on him]]. Interestingly enough if you kick him out of the party before you visit Spellhold and then visit him when you're done he'll die as soon as you come near him.

* [[spoiler:Reeve, aka Cait Sith]] in ''VideoGame/FinalFantasyVII'', though he's in the middle of a HeelFaceTurn when it's revealed.
* ''VisualNovel/DanganRonpa'' and its sequel ''VisualNovel/SuperDanganRonpa2'' each have one, though both of them are played with. In the first game, it's [[spoiler:Sakura Oogami, who is being blackmailed into being the mole]], while the second game has [[spoiler:Chiaki Nanami as the "traitor". However, both Nanami and the person she's working for (Usami) have the students' best interests at heart]].

* ''VideoGame/RomancingSaGa'' [[spoiler: Red Mage, who really is Spite; one of the Minions of Saruin; but if you saw Red Mages' clothes, the golden buckles on his front and the red coat with blueish-green hue on it is a dead give away since that quest is late in the game and you may have already fought Strife and Scorn who have a similar design other than Spite who took a human form]]

* Scias from ''VideoGame/BreathOfFireIV''. Though to be fair, he never was ''supposed'' to be on their side in the first place - apparently the party sort of forgot that he was the guard assigned to keep an eye on them.
** Fortunately, Scias takes his orders literally. He was told to keep an eye on them, not to ''stop them from leaving the castle.'' He points this out to his employer, who, annoyed, has to agree that Scias fulfilled his contract. [[spoiler: At which point Scias gives the money back when he has a case of BecomingTheMask.]]
* ''VideoGame/{{Ever17}}'' has [[spoiler:'Takeshi']] which is revealed in the final route. Minor subversion in that [[spoiler:it was being done as part of a plan orchestrated by the good guys who simply couldn't tell anyone what was going on.]]
* In ''VideoGame/LunarTheSilverStar'', [[spoiler:Nash eventually turns out to be a traitor who was working for Ghaleon, helping him spy on your every move. And depending on the version you played, Nash either turns out to be a double mole, or has a SexFaceTurn after the actions of another party member, Mia.]]
* [[spoiler:Jenkins]] is this in ''VideoGame/RedFaction: Guerrilla''. He's a variation of this though, in that he's not really with the EDF, but [[spoiler:is simply batshit insane]].
** In the first game, Hendrix is one of these for the player and the titular Red Faction. He works as Ultor's security technician, but secretly helps the Faction by providing them with information and hacking into Ultor's security systems.
* In ''VideoGame/{{Strife}}'' it's revealed about mid-way through the game that [[spoiler: Macil has a piece of the Sigil]]. He must be dealt with to finish the game but when you do so determines which ending you receive.

* ''VideoGame/MetroidOtherM'': The Deleter aka [[spoiler: James Pierce]]
* [[spoiler:Dusknoir]] in ''VideoGame/PokemonMysteryDungeonExplorers''. There's also [[spoiler:Snover]] in ''Sky''.

* ''VideoGame/SleepingDogs'' revolves around the protagonist Wei Shen being an undercover policeman within the [[TheTriadsAndTheTongs Sun On Yee]], but ''so'' deep undercover that at one point his handler voices suspicions that he'd "gone native", not least since he'd ended up killing to "prove" that he's not an undercover, and by that point had killed many, ''many'' more.
** A minor subplot has a minor character reveal his belief that Wei is a cop... except this guy is himself a police informant.
* In ''VideoGame/PerfectDark Zero'', Chandra is secretly working for Zhang Li, which she reveals after killing Dr. Carroll. She herself is sacrificed by Zhang at the end of the game to gain her life force.
* In ''VideoGame/RenegadeOps'', [[spoiler:Natasha, the scientist you've been charged with protecting for the first seven missions]], turns out to be working for the same faction as Inferno. Furthermore, [[spoiler:she's actually Inferno's superior, sent down by her organization to watch over him after one screw-up too many]].
* ''VideoGame/RescueOnFractalus'' has aliens sometimes disguise themselves as human pilots, trying to trick you into "rescuing" them, only to kill you when you let your guard down.
* Albert Wesker from ''Franchise/ResidentEvil''. Since being outed and subsequently "killed off", he returned as a superhuman, {{badass}} villain.
* The plot of the ''VideoGame/SamAndMaxFreelancePolice'' episode "The Mole, The Mob and the Meatball" was for Sam and Max to find a mole who infiltrated [[PunnyName Ted E. Bear's]] [[LegitimateBusinessmensSocialClub Mafia Free Playland and Casino.]] [[spoiler:Turns out the mole was an ''actual'' mole and he switched sides as the new Don]].
* In ''VideoGame/StarCraft'' Brood War, Samir Duran helps the Terran forces at the early missions of the campaign. Halfway through the game, he manipulates the Terran Commander Gerard Dugalle that his childhood friend, Vice-Admiral Alexei Stukov was a traitor to the United Earth Directorate. Dugalle then gives Duran the mission to kill Stukov, after which Duran reveals himself as the real traitor and works with Sarah Kerrigan.
** Then the trope is fulfilled again when Duran betrays Kerrigan at a critical hour, later revealing himself as "a servant of a far greater power" which will likely figure prominently in the sequel.
*** And now has.
* [[spoiler: Sanchez]], of ''VideoGame/SuikodenI'', turns out to be a traitor. He pledges allegiance immediately when discovered, and, despite his hand in some horrific events [[spoiler: from Odessa's death to sabotaging the Resistance's raid on the Empire's most important fortress]], [[JokerImmunity the hero doesn't execute him on the spot]]. He does spend the rest of his life in a prison though. Really, you should have known: [[spoiler: he has a [[NominalImportance face portrait]] and hangs around you, but is ''not'' one of the [[OneHundredAndEight 108]] warriors]].
* ''VideoGame/SuperRobotWars: Original Generation'' has a variation on this. He's really in with the good guys, but he's mentally programmed by the bad guys so that he can't do anything that directly goes against them. So he made a female clone of himself that doesn't have the programming before he activated.
** The sequel does this with a twist. The Shadow Mirrors sends Lamia Loveless a [[RidiculouslyHumanRobots robot]] created by the MadScientist Lemon Browning, to act as a mole to spy on Kyosuke Nanbu. The player knows she's a mole right off the bat, and the drama is that Lamia is becoming self aware, and wonders if what she is doing is right.
* In ''VideoGame/TeamFortress2'', this is the point of the Spy. You disguise as a member of the enemy team, infiltrate headquarters, act like an ally... and then stab your "teammates" in the back as soon as you get the chance.

*** And now has.
* In ''VideoGame/NeverwinterNights'', Desther Indelayne served under Lord Nasher Alagondar when Neverwinter was infested by the Wailing Death. He has the complete trust of the elven cleric Fenthick Moss and was rather suspicious of the player character's motives. After the 4 Waterdhavian reagents are recovered and a cure was created, Desther and his false Helmite priests steal the cure, revealing that they are serving the cult of the Old Ones who were behind the Wailing Death.

* [[spoiler: Sanchez]], of ''VideoGame/SuikodenI'', turns out to be a traitor. He pledges allegiance immediately when discovered, and, despite his hand in some horrific events [[spoiler: from Odessa's death to sabotaging the Resistance's raid on the Empire's most important fortress]], [[JokerImmunity the hero doesn't execute him on the spot]]. He does spend the rest of his life in a prison though. Really, you should have known: [[spoiler: he has a [[NominalImportance face portrait]] and hangs around you, but is ''not'' one of the [[OneHundredAndEight 108]] warriors.]]
* Albert Wesker from ''Franchise/ResidentEvil''. Since being outed and subsequently "killed off", he returned as a superhuman, {{badass}} villain.

* ''VideoGame/ShiningForce 2'' had a blind, injured boy named Oddler who the party takes around with them for part of the game, and later turns out to be a greater devil named Odd Eye. Interestingly, he is a redeemable evil, as he [[RedemptionEqualsDeath sacrifices himself]] to pave the way to the FinalBoss after the party defeats him in battle.
* The major subplot of the first ''VideoGame/{{Crusader}}'' game was that there was evidently a mole at the Resistance base. The character--and, in some cases, the player--[[spoiler:didn't find out it was Major Vargas until one of the last missions of the game, at which point the damage had been done]].

** In ''VideoGame/MetalGearSolidPeaceWalker'', [[spoiler:Paz and Kaz]] are revealed to be spies for Cipher, with the former presumed killed in the final battle against ZEKE.
* ''[[VideoGame/MegaManX Mega Man X4]]'''s Double initially introduces himself to X during the Maverick Hunters' conflict with their sister organization Repliforce as a rookie Maverick Hunter. He is small, clumsy and chubby, and seems pretty harmless. He presents X the 8 Repliforce bosses and acts every bit X's ally, even pleading with him to not go fight Repliforce's Colonel. However, once X has taken care of them and heads to their space station [[KillSat Final Weapon]], Double receives a transmission from Sigma to stop the Hunters from reaching Final Weapon at all costs, right in the middle of being teased by some of the Reploids in X's unit who were gearing up to follow X into space. He then proceeds to [[TransformationSequence transform into his TRUE form]]... An ass kicking demonic looking bot with laser blades on the back of his hands. Turns out he is actually semi-made of liquid metal a-la T-1000, and able to change between his real form and a smaller innocent looking one. He then proceeds to slaughter every single one of the Hunters in the Hangar in probably the most [[HighPressureBlood graphic scene ever put in a Mega Man game.]] He then goes to Final Weapon himself, and intercepts X in his small form, bursting out laughing, claiming both the Hunters and Repliforce as idiots. He transforms, much to X's shock, as he had trusted his new ally, and attacks him. After he is defeated, he reveals had been sent as a spy from the very beginning to keep an eye on X.
* ''VideoGame/WinBack: Covert Operations'': Your squad leader, who happens to be the brother of the BigBad that was offed by TheDragon turned traitor himself. Before the penultimate battle, he reveals that he sabotaged the helicopter, causing it to explode and faking his death (NoOneCouldSurviveThat), and that he killed the two teammates you found StuffedIntoTheFridge.
* Jansen Friedh of ''VideoGame/LostOdyssey'' starts off the game as The Mole, but is very bad at it, probably as a result of just not caring that much about his employer's instructions. Not suprisingly, he quickly [[BecomingTheMask discovers that he likes Kaim and Seth a lot more than he likes his boss]].
* ''VideoGame/BatenKaitos'' is an interesting case in that [[spoiler:the mole is the main character, and you don't know until the second disc. He goes on to become The Dragon for a while until his defeat at the hands of his former friends, and then performs a genuine Heel Face Turn.]]
* In ''VideoGame/TheElderScrollsIVOblivion'', several of the random citizens in Cyrodiil are actually Mythic Dawn cultists. Usually, you won't discover this until your actions make the Mythic Dawn faction sufficiently mad at you that they start to attack you on sight, although you may find this out ahead of time - say, if you burgle their house and find a set of cultist robes, or if they get attacked by something and [[ArtificialStupidity blow their cover by summoning their trademark armor]].
** In ''[[VideoGame/TheElderScrollsIIIMorrowind Morrowind]]'', [[spoiler:The Nord leader of Vvardenfell's Fighter's Guild is revealed to be a Mole for the Cammona Tong, the EvilCounterpart to the regular Thieve's Guild that wants them dead. You can either help the Nord eradicate the Thieves' Guild, or help the second-in-command of the Fighter's Guild expose and kill him.]]
** There's more than that, however. One Mages Guild quest requires you to root out a potential Telvanni spy; [[spoiler:It's the Archmages personal assistant]]. A House Hlaalu quest has you delivering new orders to their spy watching their rivals House Redoran, [[spoiler:the upper-class tailor in Ald'ruhn, the Redoran capital]]. Though one doesn't formally come up in the Thieves Guild questline, you can find a few Thieves Guild members deep undercover at the Camonna Tong HQ, the Dren Plantation.

* In ''Mission: Impossible'' for the N64 and PS1, Ethan is framed for being Max's mole in the CIA halfway through the game, then later it is revealed that the real mole is Phelps, as in the movie.
* In ''VideoGame/{{Arcanum}}'' the Mole is immediately (and unnecessarily) lampshaded by TheLancer as soon as he offers to join. If you gather the right information to convince the leader of the entire organization to do a HeelFaceTurn, then he confesses and asks to remain in your party, otherwise he invites you to an ambush ("There's something I must tell you, but you must come alone! Otherwise the information will be LostForever!")
* Reiko from ''Oneechanbara 2''. She's an agent of an organization that joins Aya in her attempt to rescue her half-sister, Saki. Turns out said organization is ''evil'', and she tagged along so that when Aya defeated the villain that had kidnapped Saki, Reiko could ''eat'' her heart and gain Baneful Blood powers. However, since this game only came out in Japan and the PAL territories, most US players only know this from the summary of the previous games included in the guides and manuals for the US-released ''Oneechanbara'' games.
* In ''VideoGame/TeamFortress2'', this is the point of the Spy. You disguise as a member of the enemy team, infiltrate headquarters, act like an ally... and then stab your "teammates" in the back as soon as you get the chance.
* ''VideoGame/WingCommander'' has several of them:
** [[spoiler: Zachary "Jazz" Colson]], in ''Wing Commander II''
** From the manual for ''Wing Commander Privateer'', the story of a station destroyed by Retros involves one, named [[spoiler: Furstenburg]], that shut down the station's defenses at a critical moment, allowing the Retros to attack unimpeded.
** [[spoiler: [[ManchurianAgent Ralgha "Hobbes" nar Hhallas]]]], in ''Wing Commander III''

* ''{{VideoGame/ARMA}} 2'' had CDF officer Nikola Nikitin, whose treachery [[spoiler:gets Razor Team captured.]] And after [[HorribleJudgeOfCharacter Miles trusts Nikitin enough to get them into this mess,]] [[spoiler:[[KilledOffForReal Lopotev shoots Miles.]]]]
* ''VideoGame/{{Wolfenstein}}'' has [[spoiler: this happen twice! The first is expected, the second isn't.]]
* In ''VideoGame/{{Anachronox}}'', [[spoiler:the first person who joins your party, Grumpos]] is The Mole and has the symbol of the Dark Servents under [[spoiler:his beard]] but it is not revealed until the final cutscene when [[spoiler:he activates The Fountain Spiral to free the Dark Servents]]. The player generally suspects nothing, the only foreshadowing is when he refuses to go to [[spoiler:Limbus, a planet which has experience with the Dark Servents and so would recognise him]], but since he plays it as being afraid because of the place's reputation, it's not telling.

* In ''VideoGame/AlphaPrime'' there is Coral Snake. Your first hint of them being the Mole is while watching a report from the villain requesting permission to terminate them because he no longer trusts them, and he later warns ''you'' not to trust them. The latter half of the game deals with the main characters accusing each other, finally leading the hero to wonder if the villain made up Coral Snake to turn the heroes against each other. [[spoiler: He didn't. Coral Snake turns out to be [[BigBadFriend Livia]], who was working for the villain's superiors the whole time. Though she probably didn't have nice plans for the villain either.]]
* ''VisualNovel/AceAttorney'' villains are really good at being moles, especially [[spoiler:Matt Engarde who you'd think would be incapable of simply brushing his teeth without his manager, much less kill someone.]] Other examples include [[spoiler:Calisto Yew aka Shih-na]] in the fifth game, and [[spoiler:Kristoph Gavin who is the player's ''[[TreacherousAdvisor freaking boss]]'']] in the fourth game.
** The DetectiveMole. [[spoiler: Both of them. Byrne Faraday and Tyrell Badd worked together on the Yatagararasu case--and also ''were'' the Yatagarasu, together with Yew.]] And [[spoiler: Luke Atmey, who claimed to be hunting GentlemanThief Masque*Demasque while he was secretly the one funding and manipulating him.]] Starting to see a bit of a pattern here...
* In ''VideoGame/BaldursGateII'' there is [[spoiler:Yoshimo. He is forced to spy on you due to a curse Irenicus put on him.]] Interestingly enough if you kick him out of the party before you visit Spellhold and then visit him when you're done he'll die as soon as you come near him.
* In ''VideoGame/WorldOfWarcraft'', the ''Cataclysm'' expansion reveals that [[spoiler:formerly relatively minor NPC Archbishop Benedictus is, and [[EvilAllAlong always has been]], a fanatical member of the [[ReligionOfEvil Twilight's Hammer cult]] that has been spying on Stormwind.]]
* ''VideoGame/DeusEx'', being a pastiche of conspiracy theories, has a large number of moles, starting with the mole paramilitary group [[spoiler:UNATCO, working for [=MJ12=]]] and tycoon Bob Page [[spoiler:working for himself]]. On a more personal level there's Harley Filben, working for [[strike:the NSF]] [[spoiler:UNATCO]] - or, more accurately: [[spoiler:[[strike:[[DoubleReverseQuadrupleAgent the Illuminati]]]] [[OverusedRunningGag MJ12]]]] and Morgan Everett's mechanic, who places [[spoiler: a bomb on Jock's helicopter.]]
* In the ''VideoGame/MassEffect2'' [[DownloadableContent DLC]], ''Lair of the Shadow Broker'' there's [[spoiler:Tela Vasir, an Asari spectre who acts as the mole to the Shadow Broker. [[{{Badass}} Ironically she provides a boss fight that is arguably even tougher than the fight with the Broker himself]]]]
** And in ''Mass Effect 3'', [[spoiler:Udina]] becomes this.
* In ''VideoGame/AssassinsCreedBrotherhood'', the evidence seems to point La Volpe towards [[spoiler:Machiavelli]] being the mole, but it really is [[spoiler: some one-eyed thief briefly glimpsed in the first Sequence.]]
** In "The Lost Archives" DLC of ''VideoGame/AssassinsCreedRevelations'', it's revealed that [[spoiler:Lucy Stillman]] was a Templar sleeper agent since before the original ''VideoGame/{{Assassins Creed|I}}''.
* In ''VideoGame/AlphaProtocol'', [[spoiler: Mina]] is a mole for the NSA, tasked with looking into the Alpha Protocol operation and bringing it down.
** Oh, there's so much more than that: [[spoiler:Parker]] is Halbech's mole within Alpha Protocol, [[spoiler:Omen Deng]] is a DeepCoverAgent for [[spoiler:Taiwan]], [[spoiler:Surkov]] is Halbech's real arms supplier in Russia, [[spoiler:Scarlet]] is the assassin sent to kill President Sung, and it's heavily implied that [[spoiler:Steven Heck]] was the one who set up the assassination plot in the first place. Plus there's all the traitors within the organizations you fight who are willing to sell you intel on their friends.

* In ''VideoGame/RenegadeOps'', [[spoiler:Natasha, the scientist you've been charged with protecting for the first seven missions]], turns out to be working for the same faction as Inferno. Furthermore, [[spoiler:she's actually Inferno's superior, sent down by her organization to watch over him after one screw-up too many]].
* The plot of the ''VideoGame/SamAndMaxFreelancePolice'' episode "The Mole, The Mob and the Meatball" was for Sam and Max to find a mole who infiltrated [[PunnyName Ted E. Bear's]] [[LegitimateBusinessmensSocialClub Mafia Free Playland and Casino.]] [[spoiler:Turns out the mole was an ''actual'' mole and he switched sides as the new Don.]]

* In ''VideoGame/DiabloIII'', [[spoiler:Adria turns out to be the high priestess of Diablo, with whom she conceived Leah for the sole purpose of being Diablo's vessel to be reborn as the Prime Evil]].
* An interpretation of [[spoiler: Iwazaru]] in ''VideoGame/{{Killer7}}''

* In ''VideoGame/DuelSaviorDestiny'' it becomes clear early on that the forces of Ruin have some sort of agent inside the academy, though their identity isn't uncovered until some time later. The mole, [[spoiler:Downy Reed]], almost acts offended when accused of being a traitor. After all, to be a traitor requires being on your side in the first place.
* One of the endings in the VisualNovel ''VisualNovel/BionicHeart'' creates a DetectiveMole for the BigBad. If you choose to free Tina and flee with Tanya without learning of Richard's whereabouts, it is revealed that [[spoiler:Tina was already under Richard's control and is now his personal mole for the police.]]

* One side quest in ''VideoGame/FalloutNewVegas'' involves exposing a Legion double agent posing as an NCR captain.
* [[spoiler:Katarine/Eine]] from [[VideoGame/FireEmblemAkaneia Fire Emblem Shin Monshou No Nazo]] is a spy that wants to kill Marth. [[HeelFaceTurn You can recruit her again later on.]]
* ''VisualNovel/DanganRonpa'' and its sequel ''VisualNovel/SuperDanganRonpa2'' each have one, though both of them are played with. In the first game, it's [[spoiler:Sakura Oogami, who is being blackmailed into being the mole]], while the second game has [[spoiler:Chiaki Nanami as the "traitor". However, both Nanami and the person she's working for (Usami) have the students' best interests at heart]].
* [[MissionControl Angel]] in ''VideoGame/{{Borderlands 2}}'' is revealed to be a spy for [[MegaCorp Hyperion]] when the player plugs Wilhelm's AI core into Sanctuary's defense systems and she uses it to lower the shields. She spends the next few chapters trying to apologize and convince the player that she's still their ally.

* In ''WesternAnimation/StarCraft'' Brood War, Samir Duran helps the Terran forces at the early missions of the campaign. Halfway through the game, he manipulates the Terran Commander Gerard Dugalle that his childhood friend, Vice-Admiral Alexei Stukov was a traitor to the United Earth Directorate. Dugalle then gives Duran the mission to kill Stukov, after which Duran reveals himself as the real traitor and works with Sarah Kerrigan.

* ''RomancingSaGa'' [[spoiler: Red Mage, who really is Spite; one of the Minions of Saruin; but if you saw Red Mages' clothes, the golden buckles on his front and the red coat with blueish-green hue on it is a dead give away since that quest is late in the game and you may have already fought Strife and Scorn who have a similar design other than Spite who took a human form]]
