* In the ''Franchise/AceAttorney'' series, each of the games' main antagonists count, as well as many of the murderers in each individual case. Naturally, discussing much about them would reveal that they're responsible, as well as, in some cases, [[BeneathTheMask their true personalities]].
** Probably the biggest example is Bobby Fulbright from ''Dual Destinies'', who is introduced 5-2 as the InspectorLestrade role that Gumshoe and Ema filled. Then the game drops a bombshell by revealing that he's actually Phantom, an emotionless agent who murdered Fulbright prior to the story's events and stole his identity, as well the killer of both Clay Terran and Metis Cykes. This is revealed ''very'' late into the game's events, but is a massive twist, especially since Fulbright is one of the last characters one would suspect as the BigBad given his role and much of the {{Foreshadowing}} towards the revelation is very subtle.
** Matt Engarde from ''Justice for All'' is a very special case as his true personality is denoted by his TwoFaced scars, hidden by PeekABangs until Phoenix Wright gathers enough evidence to reveal his secret. Therefore, anyone foolish enough to Google his name before finishing the game will find the majority of image results to show Engarde with his obviously evil scars and SlasherSmile.

*** It's almost impossible to discuss Zelgius without revealing that he's the Black Knight, which is a huge spoiler for both Radiant Dawn and its prequel.

** ''VideoGame/FireEmblemTheSacredStones''
*** Orson is impossible to talk about without revealing that he's TheMole and pulls SoLongAndThanksForAllTheGear on you. The fact that most advice to newcomers to the game will suggest never using him and stripping his inventory at the end of Chapter 5x is itself telling.

** When you finally meet President Eden face-to-face in ''VideoGame/Fallout3'', you were probably not expecting him to be an A.I.
** It is very hard to talk about Shaun from ''VideoGame/Fallout4'' without revealing that he is the leader of the Institute.
*** Also, from the Nuka World DLC of that game, the fact that John-Caleb Bradberton is alive with his [[BrainInAJar head in the jar]] makes him a huge WalkingSpoiler.
* ''[[VideoGame/{{Onmyoji}} Onmyōji]]'' has [[BigBad Kuro Seimei]]. It's pretty much a spoiler to mention that this guy ''exists'' in the first place without also revealing his [[EvilCounterpart inherent]] [[LiteralSplitPersonality connection]] to Seimei. He's [[SirNotAppearingInThisTrailer never mentioned]] in any of the game's promo material, and Creator/NoriakiSugiyama is only ever credited as voicing Abe no Seimei ''and nobody else'' in these materials.
** And then there is [[GreaterScopeVillain Yamata-no-orochi]]. Sure, you can talk about him as the PinataEnemy in the ''mitama'' dungeons, but mentioning any of his involvements with the plot reveals his being an even bigger threat than Kuro Seimei, [[BitchInSheepsClothing Yaobikuni]]'s [[TheDragon working for him]] [[EvilAllAlong all along]] and the Sword of Kusanagi's being a ChekhovsGun necessary to destroy him once and for all.
** If you try to talk about Kairaishi's role in the story, you'll find that there's nothing much to speak of beside the fact that she ''has a Kusanagi fragment in her chest''.
* ''Franchise/{{Pokemon}}''
** In ''VideoGame/PokemonBlackAndWhite'', N has one of the largest character pages of any character in the ''Pokémon'' games. It is at least 50% spoilered. [[TheManBehindTheMan Ghetsis]] is even more so, with at least 65% of his page spoilered before ''VideoGame/PokemonBlack2AndWhite2'' came out.
** ''VideoGame/PokemonXAndY'' brings us Lysandre and AZ. While the game makes few attempts to hide the fact that Lysandre is the leader of Team Flare, it does drop a bombshell regarding AZ being a 3,000 year old immortal who built The Ultimate Weapon.
** ''VideoGame/PokemonSunAndMoon'' has the entirety of the Aether Foundation, which turn out to not only be the game's [[EvilAllAlong second villainous team]] but the main villains of the game with Team Skull assisting them in getting Cosmog back. Lillie and Gladion also qualify due to their connection to [[BigBad Lusamine]]. Talking about UB-01 is also a little spoilerific, and Cosmog is nigh-on impossible to discuss without spoiling TheReveal of its evolutions.
** Blake Hall, the president of Altru Inc., in ''[[VideoGame/PokemonRanger Pokemon Ranger: Shadows of Almia]]'' is this, as he turns out to be [[BigBad the leader]] of Team Dim Sun.
** Purple Eyes from ''[[VideoGame/PokemonRanger Pokemon Ranger: Guardian Signs]]''. He comes in after the supposed ending as the new leader, and directly leads into the next villain. Also, all members of the Societea.
** Darkrai from the [[VideoGame/PokemonMysteryDungeonExplorers second set]] of ''VideoGame/PokemonMysteryDungeon'' games is an example of TheManBehindTheMan who appears [[YourPrincessIsInAnotherCastle after you think the story is over]].
*** From the same game[[OneGameForThePriceOfTwo (s)]], Grovyle and Dusknoir. Neither is what they appear to be at first glance, and spoiling Grovyle's identity also carries major reveals for the player character with it.
** Hydreigon and Munna in ''VideoGame/PokemonMysteryDungeonGatesToInfinity''. The former appears to be ObviouslyEvil initially, but turns out to be the BigGood, while the latter appears to be a DamselInDistress, but ends up being a DecoyDamsel who's plotting to eliminate the hero.
*** The Bittercold, being an EldritchAbomination that's a manifestation of the Pokemon world's misery, the true BigBad of the plot, and the motive behind Kyurem and Munna's actions.
** Bringing up Nuzleaf in ''VideoGame/PokemonSuperMysteryDungeon'' can easily spoil most of the game considering his status as TheMole thanks to Dark Matter, who due to being an OutsideContextProblem similar to Bittercold, is also a walking spoiler.
*** Talking about Mew will inevitably spoil his status as a replacement for the partner character and the ending's MetaTwist.
* ''VideoGame/RuneScape''
** How do you describe [[HarmlessVillain Wizard Grayzag]] without giving away that he TookALevelInBadass, killed a bunch of Void Knights and becomes the BigBad for the quest series?
** Kharshai's entire character pretty much bases on the fact that he is actually in disguise as Koschei the Deathless.
* In ''VideoGame/DragonAgeOrigins'', every mention of major villain Teyrn Loghain Mac Tir as a possible PlayerParty member is always covered in spoiler tags because the very fact that he can become one is a major plot twist. When that is not possible, he is conventionally referred to as "Secret Companion".
** Corypheus manages to be a Walking Spoiler two games in a row, being the secret BigBad of both ''VideoGame/DragonAgeII'''s ''Legacy'' DLC and ''VideoGame/DragonAgeInquisition''.
** Thom Rainier from ''VideoGame/DragonAgeInquisition'', a mercenary who became TheAtoner after [[MyGreatestFailure his role in an atrocity]]...by [[DeadPersonImpersonation taking on the identity of the deceased Warden-Constable Blackwall]].
** After TheStinger, it became very difficult to discuss Solas in a meaningful capacity without also bringing up the fact that [[GodWasMyCopilot he's actually Fen'Harel,]] [[TricksterArchetype the elven trickster god.]]
* The infamous Hidden Fun Stuff from ''VideoGame/DwarfFortress''. It's an UnusualEuphemism for Hell and its resident horde of demons, which will invade your fortress if you dig too deep. Many players use circus-themed euphemisms in reference to it, such as calling the demons 'clowns', and referring to the adamantine metal that usually stands between the surface world and 'the circus' as 'cotton candy'.
* The 16th playable character in ''VideoGame/TheReconstruction'', Tezkhra, is first heard of as the god worshiped by certain groups of shra.
* ''Franchise/MassEffect'':
** Sovereign as [[TheManBehindTheMan the true]] BigBad of ''VideoGame/MassEffect1'' is treated as extremely sensitive. [[AbusivePrecursors The Reapers]] in general are not considered spoiler information, but ''he'' is.
** Legion from ''VideoGame/MassEffect2'', not only as a geth ''protagonist'' (as they'd been the major enemy in the previous game), but also that [[PronounTrouble they]] can join the player's squad.
** Morinth from the same game. You can recruit her in place of her mother, Samara, if you choose to betray the latter during the climax of her loyalty mission, though to get the option to do so you need a sufficient Paragon or Renegade score. Even the fact that the Ardat-Yakshi is Samara's daughter is a twist.
** The Human Reaper, final boss of ''[=ME2=]'', whose existence has the entire Collector plot revolving around it, as well as being a ''huge'' reveal for the motivations of the Reapers.
** Javik in ''VideoGame/MassEffect3'', since his very existence spoils the fact that not all the Protheans are dead, since the first game had the few survivors' life pods run out of power while on Ilos, and by the time Shepard and company reach it they've all been powered down. Also ties into TheReveal in ''Mass Effect 2'' that the Collectors are actually indoctrinated Protheans.
** The Catalyst from the same game, since he literally only appears in the last scene of the game. This also spoils that he is an individual rather than an object.
** The creatures from the ''Leviathan'' DLC of the same game, since they're the last remnants of the first race to be turned into a Reaper and give an epically spoileriffic InfoDump.
** The ''Citadel'' DLC of the same game has its ArcVillain who turns out to be a clone of Commander Shepard. There's also Maya Brooks, who turns out to be EvilAllAlong and TheDragon to the Clone Shepard.
* ''VideoGame/{{Xenoblade}}'':
** Fiora is by far the most spoiler-heavy character in the game, considering she was implied to have died a few hours in but got turned into a RobotGirl instead. She's so spoileriffic that it is a common courtesy on forums and this wiki to refer to her by the euphemistic FanNickname "Seven." That said, her trophy in ''VideoGame/SuperSmashBros for Wii U'' and her later cameo in ''VideoGame/ProjectXZone2'' have [[LateArrivalSpoiler no such issues]].
** Metal Face's true identity is treated as a big reveal, as is Jade Face's.
** Dickson claims that he's "full of surprises." He's '''not''' joking, especially during the Mechonis Core events, when he shoots Shulk and reveals himself as TheDragon and later a member of the extinct Giant race.
** Describing Alvis as anything beyond "mysterious guy who teaches Shulk how to use the Monado" will reveal something big, mainly due to his actions after Mechonis Core and his role in [[GainaxEnding the ending]].
** Zanza, who seemed to be a semi-important character introduced and swiftly killed off at the end of the Prison Island storyline. Turns out that ''technically'' wasn't even him, and not only is he the BigBad and the FinalBoss, but one of the two gods of the world and the Monado itself!
* ''VideoGame/XenobladeChroniclesX'':
** Lao is, starting with Chapter 9, impossible to talk about spoiler-free due to his FaceHeelTurn, [[FreudianExcuse his motives for doing so]], and becoming the FinalBoss.
** Elma is the subject of a massive Reveal in the last few chapters about her true nature and her role in the overall plot.
** A few minor, unassuming [=NPCs=] who eventually become the antagonists of missions fall into this, especially Powell, Alex, Ornella, and Justin.
** The existence of the Tree Clan Prone is largely kept secret until a good way through the game ([[InterfaceSpoiler unless you take a peek at the achievements list]]), at which point they are involved in many missions thereafter.
* ''VideoGame/TheLegendOfHeroesTrailsOfColdSteel'' has several, both from the first game and the sequel. Note that all [[WalkingSpoiler Walking Spoilers]] for the first game become {{Late Arrival Spoiler}}s in the sequel (to the point where watching the trailer for the sequel spoils almost the entire first game).
** From the first game:
*** Crow Ambrust. He's a student at Thors a year above Rean who loves gambling. And this is all you can say about him without major spoilers.
*** Vita Clotilde and Misty. Them being the same person is the ''least'' of it. Vita is presented as such a minor, irrelevant character that the fact she even is a WalkingSpoiler [[TheDogWasTheMastermind is itself a huge spoiler.]]
*** Emma and Celine. It's clear there's ''something'' odd about Emma right from the start, but her and Celine's true purpose is only revealed at the very end of the game.
** From the sequel:
*** Rufus Albarea. Starts off as just Jusis' AloofBigBrother, but he turns out to be central to the single biggest plot twist in a game already full of them. As this reveal puts all his previous actions in a totally new light, it's difficult to talk about him without spoiling anything.
*** Giliath Osborne. You know you're one of these when you manage to derail the villains' plans simply by ''showing up''.
* The above game's prequel, ''VideoGame/ZeroNoKiseki'' also has quite a few:
** Joachim Gunther. Introduced as a friendly doctor at St. Ursula. Turns out he's [[BitchInSheepsClothing anything but]]: He's actually one of the few remaining members of the D∴G Cult, which kidnapped children and performed various painful experiments on them.
** Ian Grimwood, Crossbell's public lawyer. He's presented as such a minor character that his role in the sequel is a huge twist: He's the one who murdered [[TheHero Lloyd's]] brother.
* Wheatley turning out to be an antagonist in ''VideoGame/{{Portal 2}}'' is meant to be a big twist. Thus, spoilers. Everywhere.
** Cave Johnson being a character in the game, albeit [[PosthumousCharacter posthumously]], as he is only "present" in the ruins of the old Aperture labs that are the setting for the second Act. Which for extra points are only visited after aforementioned Wheatley becomes the antagonist.
** Similarly, it's hard to talk about Caroline without revealing that [=GLaDOS=] is the result of the aforementioned Cave Johnson [[BrainUploading uploading her into the database without her consent]].
* ''VideoGame/BlazBlue'': One for every game just about, and almost always revealed in the game's GoldenEnding to boot.
** ''Calamity Trigger'':
*** It's nigh-impossible to talk about Hakumen without revealing that he is [[TheRival Jin Kisaragi]] from a previous iteration of the time loop.
*** The mild-mannered pacifist Captain Hazama was one himself, being the vessel for one of the BigBadEnsemble, Yuuki Terumi.
** ''Continuum Shift'':
** Saya appears to be Ragna and Jin's missing little sister. Turns out that she's actually TheManBehindTheMan and the head of the organization the two have been fighting against the whole time.
*** Mu-12 was one as well, being Noel Vermillion's SuperpoweredEvilSide and revealing that she was created just like her sister units and being a clone of the aformentioned Saya.
** ''Chronophantasma'':
*** Izayoi for ''Chronophantasma'' continues the tradition of each game having one such character introduced. Specifically, it's the true form of the weapon that Tsubaki Yayoi has been using throughout the entire series.
** ''Central Fiction'':
*** Susanoo is Yuuki Terumi's OneWingedAngel form, and reveals his true identity as the original consciousness of the Susanoo Unit. Terumi also slayed Hakumen to achieve this form AND was the one who enabled humanity to find the Susanoo Unit and thereby make contact with the Master Unit kickstarting the events the entire series to begin with.
*** The game's title refers to Ragna himself, being the "dream observed by god" or more simply, the primary reason the time loops keep occurring. The Master Unit would constantly reset and change the world whenever Ragna died and so to ensure the world moves forward without interference, Ragna [[{{Retgone}} removes himself from the world as well as any memory that he ever existed.]]
* Yomiel, the mysterious BigBad of ''VideoGame/GhostTrick''. When he shows up, the game pretty much heads into one MindScrew and PlotTwist after another. For that matter, Ray and Sissel (the player character himself) also count since the game is about finding out [[AmnesiacHero what his identity was before he was killed]].
* ''VideoGame/BatmanArkhamCity'':
** Clayface, who for those familiar with [[VoluntaryShapeshifting his powers]] merely mentioning his name gives a big clue to a major twist just before the end of the game. Overlaps with InterfaceSpoiler as looking at The Joker with Batman's Detective Vision shows he has no bones or internal organs.
** Simply mentioning Hush spoils the ending to the "Identity Theft" sidequest. Although, those familiar with the character can already guess who is responsible.
** Discussing anything about the Mad Hatter spoils a (admittedly very short) sidequest as well as the source for a lot of Hugo Strange's influence and resources.
* Joshua, and, to a lesser extent, Hanekoma in ''VideoGame/TheWorldEndsWithYou''. Kitaniji too, as you don't really learn his real role in the plot until the very end. And Eri to an extent, as merely ''describing her appearance'' can spoil a significant plot twist regarding Shiki.
* Many villains from ''Franchise/{{Kirby}}'' end up as this trope, due to most of them being [[VileVillainSaccharineShow quite darker than the rest of the franchise]]:
** Magolor from ''[[VideoGame/KirbysReturntoDreamLand Return to Dream Land]]'' and Marx from ''VideoGame/KirbySuperStar'' are both notable for betraying Kirby and his friends by using them as {{Unwitting Pawn}}s.
** Queen Sectonia from ''VideoGame/KirbyTripleDeluxe'' comes along with almost no foreshadowing whatsoever, and is quite notable for being one of the only cases of LightIsNotGood in the franchise.
** Zero and his undead form, appearing in ''VideoGame/KirbysDreamland3'' and ''VideoGame/Kirby64TheCrystalShards'' respectively, come off as a major surprise due to the fact that both of them [[FamilyUnfriendlyViolence bleed in what's supposed to be a family-friendly franchise]].
** The true form of Star Dream from ''VideoGame/KirbyPlanetRobobot'' is arguably the ''largest'' plot twist in the entire franchise's history, as it ties back to [[VideoGame/KirbySuperStar one of the franchise's oldest games]] in a very unexpected way.
*** President Haltmann's personal motives are kept tight-lipped until much later in the game, and [[TheWoobie for good reason]].
* Normally, Kor from ''VideoGame/JakIIRenegade'' would just be your typical old man. Most of his tropes come from the fact that he's really [[BigBad the Metal Head Leader]] in disguise. What's particularly ''clever'' about this one is that Kor acts as TheMentor to The Kid and a CoolOldGuy towards Jak and Daxter. Most players likely won't bat an eye at some of the spoiler-tags because they might ''assume'' he suffers MentorOccupationalHazard (justifying his absence from later games), and even then they might be misled into thinking that the secrets he's obviously hiding are considerably more benevolent than they turn out to be.
* ''VideoGame/KnightsOfTheOldRepublic'':
** Revan being the PlayerCharacter of the first game is a major plot twist, causing the former Dark Lord of the Sith to become the main source of spoilers of the game. This makes the ''first sentence'' of the plot synopsis for the game on Wookieepedia (unless it has been changed by the time you read this) a huge spoiler for TheReveal more than halfway down the plot.
** The second game has Kreia. She casually mentions early on she used to be a Sith Lord, and that's the ''least'' of the spoilers regarding her.
* ''VideoGame/StarWarsTheOldRepublic'':
** It's hard to mention much about Master Syo Bakarn without bringing up that he's a [[ManchurianAgent Child of the Emperor]] and the Jedi Consular's final boss.
** Likewise, just try talking about the Jedi Knight's TokenEvilTeammate Lord Scourge ''without'' using spoilers.
** The Smuggler storyline has Darmas Pollaran, who is revealed later in the story to be an Imperial agent who has been manipulating the Smuggler to do the Voidwolf's bidding throughout their career as a Republic privateer.
** It's difficult to discuss much about more than a few characters from the Imperial Agent storyline without spoiling the various plot twists, though the biggest examples would be Darth Jadus, who turns out to be the BigBad of the Agent story's Act 1, and Hunter, who is not only the final boss of the Agent storyline, but also revealed to be a woman.
** With Revan ''and'' the Exile making final performances in the game, there are a couple of flashpoints that are nothing but spoiler tags.
* ''VideoGame/KidIcarusUprising''
** After you defeat Medusa and the fake credits roll, [[TheManBehindTheMan the true villain, Hades]], comes in and takes over the Underworld Army. And since we were led to believe that Medusa was the villain with no hints of Hades being in the game…
** To a lesser extent, pretty much everyone who is introduced after Chapter 9, which is built to look as much like the final dungeon as possible. The Chaos Kin is an especially strong example, since talking about it not only spoils that the game goes on after Chapter 9, but it is also likely to reveal much about the Chaos Kin's [[WhamEpisode story arc]], particularly Pit being trapped in a ring for three years and Palutena turning evil.
* The Golden Spider/Chakravartin from ''VideoGame/AsurasWrath'', seeing he is the true BigBad and the {{god}} of his universe, having manipulated all the events in the game for his own interest. [[note]]Before the character page was redone with unmarked spoilers, only one trope applying to him was unspoiled at best.[[/note]]
* ''Videogame/DeadlyPremonition''
** Forrest Kaysen. Many spoilers are required to conceal that the fat, jolly tree salesman is not only the BigBad of the game, but a HumanoidAbomination to boot.
** George gets quite a few spoilers too, by virtue of being both the Sheriff "helping" York with the investigation (and thus receiving a lot of screen time throughout the game) and the New Raincoat Killer; as does Thomas, due to his relationship with George, his own status as a minor villain, etc.
** Zach, York's NotSoImaginaryFriend. The first reveal of his origins, given midway through the game, is a big enough spoiler on its own, but there are spoilers ''behind'' those spoilers, escalating all the way up until the end of the game, when Zach's true nature as the [[DecoyProtagonist real protagonist]] is revealed, and [[TomatoInTheMirror York is shown to be the imaginary one.]]
* About 2/3 of the way through ''VideoGame/FinalFantasyV'', the party meets Krile. She is a friendly young girl. This is the most detail you can describe her with if you don't want to reveal that she is Galuf's granddaughter, a princess (because he is really a king), or that she [[TakeUpMySword takes his place]] upon his death.
* ''VideoGame/FinalFantasyVI'' has Terra Branford. These days the fact that she is half-Esper has entered ItWasHisSled territory, even being a central part of her combat methods in ''VideoGame/DissidiaFinalFantasy'', but at the time it was a pretty big surprise only revealed several hours into the game (although it was {{foreshadow|ing}}ed before then).
* ''VideoGame/FinalFantasyIVTheAfterYears'' has the Creator. Not only is it impossible to describe without spoilers, its name and even its very ''existence'' are major spoilers.
* ''VideoGame/TheBindingOfIsaac''
** The game takes the cake with '''five''' different examples, primarily due to the abundance of [[BrutalBonusLevel bonus levels]]. The first two, Mom's Heart and It Lives, are mostly out of this territory since their section of the dungeon is almost immediately unlocked. Satan, secret boss of Sheol, is considerably more of a spoiler, but probably more well-known since the Halloween update has been out for a while. The biggest is Isaac, the boss of the Cathedral in the DLC Wrath of the Lamb.
** The Chest. It's the ''*deep breath*'' mega ultimate super-secret final level. It can only be reached by defeating, well, yourself in The Cathedral while holding The Polaroid (it's a Polaroid photograph depicting three people, most likely Isaac, his mother and his father). Getting through ''that'' and beating its boss (???/Blue Baby) will give you what the developers of the game themselves call the closest thing the game has to a canon ending.
** The remake ''Rebirth'' adds a few more. The first is the Dark Room, a floor of equal standing to the Chest. You reach it by beating Satan enough times and unlocking a dark version of the Polaroid called the Negative. Its boss is a demon called The Lamb, and beating it unlocks an ending where Isaac goes missing.
** Beating either ??? or The Lamb allows you to fight the statues in the Angels Rooms, who formerly just gave you an item in the Wrath of the Lamb DLC. Beating two angel statues allows you to fight the definitive true final boss of the game: Mega Satan.
** There's also the infamous SecretCharacter known as The Lost. He's a OneHitPointWonder who has a ''[[GuideDangit very complicated]]'' unlock process.
* In ''VideoGame/DiabloIII'', the true identity of the Stranger that fell from the sky is not revealed until the very end of Act I, where it turns out to be a newly-human Tyrael who has sacrificed his angelic status to aid humanity directly against the last two Lords of Hell. He plays a major role in the rest of the game, serving as the de facto leader of your small party and even taking up his sword, El'druin, to battle alongside you at certain points in the final two acts.
* Tiki Tong in ''VideoGame/DonkeyKongCountryReturns''. If you lose a life in any level, you get a silhouette of the instrument tiki's face as the screen transitions to the lose a life screen. In the volcano, which is the last world, Tiki Tong's face is replaced with a question mark before you meet him.
* In ''VideoGame/JadeEmpire'', the three main antagonists - Death's Hand, Emperor Sun Hai and Master Sun Li - fall under this trope. Said characters play with the BigBad and TheManBehindTheMan tropes, causing a lot of spoiler tags on their entries in the character sheet.
* ''Videogame/FireEmblem:''
** ''VideoGame/FireEmblemAwakening:''
*** "Marth" not actually being the [[VideoGame/FireEmblemShadowDragonAndTheBladeOfLight original Marth]] is one of the few things that ''can'' be left unspoilered... but only if you construct the sentence without gendered pronouns, because this Marth is in fact Lucina, the main character's ''[[KidFromTheFuture daughter]]'' [[KidFromTheFuture from the future]].
*** The Hierophant is introduced as simply someone high up in the Plegian order, but then they take off their hood and it's revealed they have the same appearance as the player-created Avatar...because they're actually the Avatar from the BadFuture, possessed by Grima.
** ''VideoGame/FireEmblemFates:''
*** King Garon is a major one. The fact that he's the BigBad of ''Birthright'' and ''Conquest'' [[ObviouslyEvil isn't much of a spoiler]], but what ''is'' is that he ''isn't really Garon'': the real Garon is DeadAllAlong, the Garon we see is a monster posessing his corpse.
*** Takumi is the other big one. Originally introduced as the younger brother of the Hoshido siblings who [[DislikesTheNewGuy doesn't trust the main character very much]], it's hard to talk about him without mentioning that his envy and MiddleChildSyndrome [[MoreThanMindControl results in him]] being posessed by the GreaterScopeVillain, and that he's the FinalBoss of the ''Conquest'' route.
*** Flora, one of Corrin's maids, also counts, as her becoming an AntiVillain on the ''Birthright'' route, and being DrivenToSuicide after being defeated, comes as a major shock.
*** Gunter is set up as the CrutchCharacter, but seemingly suffers an unavoidable PlotlineDeath very early in the game. On ''Conquest'', this is revealed to be a DisneyDeath, but his true role doesn't become clear until ''Revelation''.
* ''Franchise/ProfessorLayton''
** Clive, from ''VideoGame/ProfessorLaytonAndTheUnwoundFuture''. AKA, Future Luke. It's difficult to talk about Clive's real personality without spoiling the time travel disaster from 10 years ago, or the fact that one of your traveling companions is the BigBad.
** Dimitri Allen AKA, Dr. Alain Stahngun and Future Layton also counts, especially given his ties to the backstory.
** From ''VideoGame/ProfessorLaytonAndTheMiracleMask'' we have Randall Ascot, AKA The Masked Gentleman. Referring to him by name reveals that Randall actually ''didn't'' die in the backstory. Though, the amount of buildup they give the character in his backstory, it's almost impossible to not see that twist coming.
** From ''VideoGame/ProfessorLaytonAndTheAzranLegacy'', there's Leon Bronev, who is not only the BigBad, but Layton and Descole's father, Emmy's HonoraryUncle and boss, and a somewhat more sympathetic character than he initially seems.
* Pat Sprigs in the first ''VideoGame/MegaManStarForce'' is at first just a student in Geo's class. Then it's revealed he was abandoned by his parents in Dream Island, has a SplitPersonality and also hosts an FM-ian. And that's just the tip of the iceberg...
* ''VideoGame/{{MOTHER 3}}''
** The Masked Man had many of his tropes spoilered because he was actually Lucas' brother Claus. This warranted a hard split between the Masked Man's tropes and Claus' tropes.
** Porky, since before he appears there's little indication that the game's plot is actually directly connected to [[VideoGame/EarthBound the previous game]].
** [[VideoGame/{{Mother 1}} The first game]] had [[LukeIAmYourFather George, Maria]] and [[BigBad Giegue]], and their connections to the main character.
* ''VideoGame/ShinMegamiTenseiII'':
** Zayin is advertised alongside Aleph, Beth, Gimmel, and Daleth as a major character. The twist is that, of those characters excluding [[TheHero Aleph]], Zayin is the only one who actually stays as a major force throughout the game. He ultimately becomes a BigBad in his own right and is the direct leader of the Law faction in God's name. Furthermore, he is actually Satan, and he redeems himself on the Law route.
** The Center Elders are actually the Archangels. Gabriel is a decent person, but Michael, Raphael, and Uriel are far worse than they were in [[VideoGame/ShinMegamiTenseiI the last game]] and are the main antagonists for a good portion of the game, at least until Aleph and Hiroko kill them.
** YHVH, the GreaterScopeVillain for Law, is the FinalBoss and final antagonist of the game. This one, [[NoExportForYou against all odds]], fell into ItWasHisSled category, to the point where it's the first thing people generally find out about the game.
* ''VideoGame/ShinMegamiTenseiIIINocturne'':
** Hikawa, Isamu, and Chiaki go OneWingedAngel and are, in their separate fights, all the penultimate bosses of the game. This is especially true for the latter two, who go crazy as a result of their experiences.
** Futomimi and Sakahagi are actually the incarnations of the positive emotions of a child serial killer and the negative emotions of a failed businessman, respectively.
** Hijiri is also a Manikin, though a special one who, like Futomimi and Sakahagi, comes from one human. Furthermore, he may or may not be [[VideoGame/ShinMegamiTenseiII Aleph]], but at the very least, he was punished by God for committing the ultimate sin.
* ''VideoGame/ShinMegamiTenseiStrangeJourney'':
** The Three Wise Men are the leaders of the Law faction. There's not much else to them, but they end up being defined by this.
** Mastema, rather than being a polite, caring angel, is actually a twisted, hate filled, prejudiced monster. This is only revealed on the Chaos path, but his actions go as far as to disgust Lucifer.
** Captain Jack and his subordinates seem to be affable folks looking to gather forma for a business client, offering their services if you obtain some rare forma for them. You later find out that [[HumansAreTheRealMonsters they're some of the biggest monsters in the game]], tearing apart demons and putting them back together in a crude attempt at demon fusion as experiments on behalf of said client and attempting to fuse your comrade Jimenez -- also a human -- with his pet demon.
** Mem Aleph by virtue of Maia Ouroboros from three sectors before [[DiscOneFinalBoss being presented like the final boss of the game]].
* ''VideoGame/ShinMegamiTenseiIV'':
** The Black Samurai is Lilith. She, along with Tayama, is a major antagonist up until the White show up.
** Tayama does not have Tokyo's best interests at heart and harvests brains from children and dissenters.
** The White's existence is a spoiler, but their goals of omnicide and their despair are even worse.
** Merkabah and Lucifer, the alignment leaders. Neither are brought up until the end of the game, yet they become the main antagonists.
** Masakado is your greatest ally in the Neutral path and the presumed leader of the National Defense Divinities. He is also the last of the DLC bosses. He doesn't even appear at all or gets mentioned to on any non-Neutral path unless you buy and use his DLC.
** Mastema isn't really DemotedToExtra, but rather, a figure that plays upon both the idea that he made a HeelFaceTurn and the idea that he hasn't changed a bit. He also sealed away the Archangels.
* ''VideoGame/ShinMegamiTenseiIVApocalypse'':
** Shesha grows sentient throughout the game and eventually impersonates Flynn from Tsukiji Konganji until after Merkabah and Lucifer's deaths, where he delivers the game's biggest WhamEpisode.
** Merkabah and Lucifer are actually Satan. Satan has been perpetuating the ForeverWar through his two halves.
** YHVH is, once again, the FinalBoss. He was the one responsible for Satan's actions.
** Jonathan and Walter return to help in the final battle with YHVH on the Peace Route.
** [[VideoGame/ShinMegamiTenseiI The Hero]], [[VideoGame/ShinMegamiTenseiII Aleph]], and [[VideoGame/ShinMegamiTenseiIIINocturne the Demi-fiend]] return in the final DLC to fight against Stephen, who in turn turns out to be more powerful than YHVH.
** The Great Will aka the Axiom, the ambiguous divine entity that's been alluded to many times throughout the series, is finally revealed in this game to be a ''BigGood'' to humanity, having created the messiahs Nanashi/Akira and Flynn/previous-summoner-of-Masakado to defeat YHVH, who is a rogue avatar of it.
* ''VideoGame/{{Persona 4}}''
** Namatame and Izanami. Both were introduced in the very beginning of the game, but their characterization was so minor that the player is likely to have forgotten them completely- particularly Izanami, who's a nameless gas attendant who only shows up near the beginning and on rainy days. The revelation of what Namatame did marks the beginning of the point where the game becomes a conga line of plot twists, and Izanami turns out to be TheManBehindTheMan [[OverlyLongGag Behind The Man Behind The Man Behind The Man]] that was responsible for just about ''everything'' that had happened up until that point.
** Tohru Adachi is the murderer. The amount of tropes that comes with this revelation is just staggering, to the point that the post-reveal tropes about him were moved to a different page.
* ''VideoGame/{{Persona 3}}'':
** Ikutsuki is introduced as the BigGood, but in reality, he tricked you into killing the Shadows to cause the Fall.
** Ryoji initially seems like just another transfer student, but in reality, he's Death. Talking about him also spoils that the game doesn't end after you kill the Hanged Man, the last of the Full Moon Shadows.
** Aigis for [[SealedEvilInACan sealing Death inside the protagonist 10 years ago]].
** The protagonist's homeroom teacher Ms Toriumi, since it's pretty much impossible to talk about her without mentioning she's actually the Hermit Social Link, something that's hidden until near the end of the game, after you complete the link.
* ''VideoGame/{{Persona 5}}''
** Kunikazu Okumura and his daughter Haru. It's relatively difficult to talk about them without revealing that after Kunikazu's heart is stolen, the Conspiracy kills him, to [[HeKnowsTooMuch keep him quiet]] and frame the Phantom Thieves for his murder, which also profoundly impacts Haru.
** Lavenza, who's the true avatar of power in this game, and a fusion of Justine and Caroline. Discussing her spoils several plot twists, such as ''why'' she was split in two.
** Goro Akechi. He's initially introduced as a detective investigating the Phantom Thieves, until he joins the party (which, unlike with the other Thieves, was not officially publicized). He turns out to be [[TheMole the traitor in the party]] that was mentioned at the start of the game, the "Black Mask" Persona user who killed Futaba's mother and Haru's father, a Wild Card user like the protagonist, and the [[BastardBastard illegitimate son]] of [[BigBad Masayoshi Shidou]].
** Yaldabaoth, the Demiurge. Like Izanami, his true identity and role are only properly revealed at the end of the game, and among them is the fact that he impersonated [[BigGood Igor]] and has been manipulating you for the entire game.
* In ''VideoGame/EVOSearchForEden'', the FinalBoss and Big Bad, Bolbox, as well as the {{Greater Scope Villain}}s and {{Well Intentioned Extremist}}s, the Whispers/Martians, are extremely spoilerifc. Bolbox isn't even hinted at until the end and the Whispers only appear in secret areas before the ending.
* The FinalBoss of ''VideoGame/{{killer7}}'', Greg Nightmare, deals with this due to being killed before his debut and being involved with a massive conspiracy about the power of America.
* In ''VideoGame/HyperdimensionNeptuniaVictory'', Rei fits this trope like a glove. Prior to release, she's only billed as one of the Seven Sages, aka the villains of the game. What Compile Heart ''doesn't reveal'' is that she's the one who sends Neptune into the past, pulls off an epic SlasherSmile, and surprising a lot of gamers, is the TrueFinalBoss instead of Magiquone/Arfoire.
** Its sequel ''VideoGame/HyperdimensionNeptuniaVictoryII'', we have Kurome Ankokuboshi. Unlike Rei, she doesn't have any mention in some preview articles. However, one of the premises suggesting one of the main characters will fall into the dark side. At a first glance, many player believes Neptune is the one who fell into dark side, but it reveals that Uzume (particularly the original one) ''is'' the one who fell, as well as the one who responsible for the destruction of her Zerodimension's counterpart dimension and Gold Third incident.
* ''Franchise/MetalGear''
** Big Boss in ''VideoGame/MetalGearSolid4GunsOfThePatriots'' appears for the last hour (give or take) of the game[[note]]A game that, on a player's first playthrough, would take at least ''nine hours'' to complete from start to finish[[/note]]. His whole presence is a spoiler in on itself, along with Major Zero, since Big Boss was supposed to have been dead for almost twenty years and Zero would be clocking in ninety years old at the very least. Both of them, their presence, and their allegiances are also crucial to understanding about half the plot of the series, so anything they say can become a spoiler.
** Senator Steven Armstrong in ''VideoGame/MetalGearRisingRevengeance''. While seemingly a behind-the-scenes villain, one could not have guessed that the guy turns out to be a nanomachine-enhanced freak of nature capable of tossing Raiden around like a ragdoll. However, he's quickly becoming a FountainOfMemes for this very reason, as well as being an absolutely hilariously hammy villain.
** ''VideoGame/MetalGearSolidPeaceWalker'' has Paz Ortega. Fans can't talk about her without discussing her reveal as TheMole near the end of ''Peace Walker'', her [[DisneyDeath apparent death]] at the end of said game and, more recently, confirming said DisneyDeath in ''[[VideoGame/MetalGearSolidVThePhantomPain Ground Zeroes]]'' only to kill her off ''again''.
** ''VideoGame/MetalGearSolidVThePhantomPain'' has Ishmael, the Medic from ''[[VideoGame/MetalGearSolidVThePhantomPain Ground Zeroes]]'', and Venom Snake himself. Giving details about any of them will spoil the major TwistEnding the game has, as all three are directly connected to it.
* ''Franchise/TheLegendOfZelda'':
** ''VideoGame/TheLegendOfZeldaOcarinaOfTime'' has Sheik, the enigmatic {{Ninja}} who helps Link enter the various temples in the second half of the game and who is revealed right before TheVeryDefinitelyFinalDungeon to actually be Princess Zelda in disguise.
** ''VideoGame/TheLegendOfZeldaMajorasMask'' has the Mask itself. For most of the game, you're led to believe that all the problems was the Skull Kid's doing, then you find out that [[DemonicPossession The Mask itself was controlling the Skull Kid]].
** Demon King Demise from ''VideoGame/TheLegendOfZeldaSkywardSword'', due to being [[BigBad Ghirahim]]'s master, and [[GreaterScopeVillain the very reason for Ganondorf's existence]], who himself is a Walking Spoiler [[HijackedByGanon depending on the game]].
** Hilda from ''VideoGame/TheLegendOfZeldaALinkBetweenWorlds'' due to her TragicVillain BigBad status, where the previous BigBad was made out to be only Yuga. She's the one who wants to revive Ganon in this game. Ravio also counts since he's actually the Lorulean counterpart to Link himself, which isn't revealed until after defeating the FinalBoss.
** Dorian from ''VideoGame/TheLegendOfZeldaBreathOfTheWild'', due to him turning out to have been a defector from the Yiga Clan whose wife was killed by them in retaliation and who was forced to spy on Kakariko Village and eventually steal the Sheikah Heirloom to keep them from killing his daughters as well. Before the quest to retrieve the Heirloom, you are lead to believe he is just a minor guard [=NPC=].
* Everything about Oersted from ''VideoGame/LiveALive'', other than maybe the first half hour of his chapter, is a pretty big spoiler.
* The Trinity in ''VideoGame/{{Skullgirls}}''. As of the non canon storylines they haven't made an actual appearance in the game, other than an EarlyBirdCameo in the GainaxEnding[=/=]{{Cliffhanger}} ending upon beating Double's Storyline, which suggests that none of the storylines are canon, and that the True Ending turns out to be a SequelHook.
* Franchise/SonicTheHedgehog
** ''VideoGame/SonicHeroes''
*** Mentioning that Shadow the Hedgehog is in this game would clue you in to the fact that he didn't really die in [[VideoGame/SonicAdventure2 the previous game]]. Then again, the fact that [[VideoGame/ShadowTheHedgehog he had his own game after that]], and has appeared in most ''Franchise/{{Sonic|TheHedgehog}}'' games in some fashion since then, the fact that anyone ever thought he was actually dead is taken for granted.
*** Metal Sonic being the BigBad in that game, [[TrailersAlwaysSpoil although spoiled by trailers and even in-game cinematics and other materials]], was a ''very big'' revelation at the time of ''Heroes''' release (and the page here still treats it as such by keeping the entries pertaining to Metal Sonic and his actions during the game, both directly and indirectly, spoiler tagged), [[ItWasHisSled although it's not so much heavily under wraps these days]].
** In [[VideoGame/SonicStorybookSeries Sonic and the Black Knight]], Merlina's really the BigBad throughout the entire game, despite her benevolent actions at first which hides her ulterior motives.
** ''VideoGame/SonicMania'' has Infinite's involvement. It is implied that the entire plot of the game is chasing after power that is connected to Infinite and the events of the end of the game sets the entire stage of ''VideoGame/SonicForces'' in motion.
* All the player characters other than Max, the main character, in ''VideoGame/{{Sanitarium}}'' are hard to talk about because they're actually forms/alternate personalities that [[TheNthDoctor Max shapeshifts into]]. By itself, that might not matter, but the shapeshifting doesn't occur until about 1/3 of the way into the game and is meant to be a [[ShockingSwerve VERY unexpected plot development]]; it's not something that the player is intended to know ahead of time.
* ''VideoGame/MegaManX''
** Lumine in ''8'', who's kidnapped at the very beginning of the game and isn't seen again until the end, when he (allegedly) [[KilledOffForReal kills Sigma off for real]] and reveals himself as the true mastermind of the game's events.
** Sigma ''would'' count in some ''MMX'' games (just like Dr. Wily would technically count for the [[VideoGame/MegaManClassic classic series]]), if him being TheManBehindTheMan wasn't so common that someone else being the BigBad of the game [[MetaTwist is a bigger twist.]]
* ''VideoGame/MegaManXCommandMission'' has Colonel Redips, who sends Maverick Hunters X and Zero on a mission to quell the rebellion army. After you defeat Epsilon however, Redips quickly stabs them in the back after they return the supra-force metal to him, revealing himself as TheManBehindTheMan to Epsilon and the real mastermind behind the game's events. Spider even more so, because he was Colonel Redips the ''whole'' time.
* Killabilly from ''VideoGame/LollipopChainsaw'', who appears [[NiceJobBreakingItHero only after Juliet has killed all five Dark Purveyors.]]
* Angel in ''VideoGame/{{Borderlands 2}}''. It is very difficult to talk about her in any respect without revealing that she is working for Handsome Jack, is a Siren, and is also Handsome Jack's daughter. Technically referring to her as Angel rather than The Guardian Angel is itself a spoiler.
* ''Franchise/SuperMarioBros''
** Dimentio from ''VideoGame/SuperPaperMario'' is near impossible to talk about without revealing SOMETHING about his motives.
** The very fact that the final boss of ''VideoGame/MarioAndLuigiPartnersInTime'' is ''not'' [[BigBad Princess Shroob]], but her older sister, and that the Cobalt Star Mario and Luigi spent the whole game assembling is actually [[SealedEvilInASixPack her can]], is a massive twist, making the Elder Princess Shroob a definite example.
** The Zeekeeper in ''VideoGame/MarioAndLuigiDreamTeam''. He's only ever encountered about three quarters of the way through the game, is the mystical deity of the island and completely subverts most expectations about how a god like figure is supposed to behave. And plays a major part in the ending.
** ''VideoGame/SuperMarioSunshine'' features the true identity of Shadow Mario, who goes on to become a recurring character in the series.
* Getting a good look at Dracula from ''VideoGame/CastlevaniaLordsOfShadow2'' and ''VideoGame/CastlevaniaLordsOfShadowMirrorOfFate'', or even hearing him speak, gives away the big [[TheReveal twist]] from the end of the first ''VideoGame/CastlevaniaLordsOfShadow''.
* ''VideoGame/TheWalkingDead''. The Mysterious Stranger, when finally revealed, is one huge spoiler since his life is ruined by your group. He questions all of your hard choices. The fact that he's an AntiVillain instead of a BigBad, makes him a walking spoiler.
** Kenny in the Season 2 can count as one too, since his last appearance in Season 1 implied that he died.
** The final battle of Episode 5 Season 2 is a massive spoiler, because it's a fight to the death and it happens between two of your allies; Kenny and Jane.
* ''Franchise/AssassinsCreed''
** Haytham Kenway was successfully kept a secret from audiences for years up until the game's release, yet the first three sequences are played as him and not the main character, his son Connor. The end of [[VideoGame/AssassinsCreedIII the third game]] reveals him to be a templar, and he serves as the BigBad alongside Charles Lee for the rest of the game. Since much of the game's major twists involve him and his relationship with his son, it's pretty hard having a spoiler-free discussion about him.
** ''The FramingDevice of the entire franchise'' is a huge spoiler in and of itself. The existence of [[GeneticMemory the Animus]] was kept secret during the development of [[VideoGame/AssassinsCreedI the first game]], and official media for the sequels continue to say as little about the modern-day plot as humanly possible.
* ''VideoGame/ProjectXZone'': Meden Traore definitely counts and the Portal Stone by extension. He is the leader of the Oros Phlox Organization that keeps hounding you throughout the game, and until he actually appears halfway through the game we're led to believe that Due Flabellum (who turns out to be his wife) is the leader. [[WellIntentionedExtremist His goal is to merge all worlds into one world to make it all a better place then they were individually]], [[RealityWarper completely messing with the boundaries of time, space, life, and death to accomplish this]]. He's also the FinalBoss in the game, opening the intro movie tells you that much once you recognize him. And the kicker is that he and the rest of the Oros Phlox are [[AnthropomorphicPersonification the manifested will]] of the [[ArtifactOfDoom Portal Stone]] itself, making the very artifact thought to be stolen from Mii's mansion the BigBad pulling the strings from behind the scenes ''the entire time.''
* ''VideoGame/{{Ib}}'': Since nearly all of Mary's screen time lends itself to her being a JerkassWoobie CreepyChild [[AxCrazy with a palette knife]] (after being introduced as a CheerfulChild foil [[TheStoic Ib]]), it's very difficult to have a spoiler-free discussion regarding her character.
* Everything in the Sacred Grounds in ''VideoGame/CaveStory'' due to the area's existence being a huge spoiler, which includes both of its bosses, the Heavy Press and Ballos.
* Pretty much every character in ''Videogame/StarStealingPrince''. Astra's not really a DamselInDistress, Snowe's parents are not really dead, Snowe's parents aren't even the rightful rulers of the land, the rightful ruler was even worse than they were and they were pretty awful, and there's also the whole demon thing. Even the girl who appears in Snowe's dreams is not just a dream representation of Astra but a character in her own right, and you'd never guess that unless you went for the BonusDungeon.
** In ''Literature/EphemeralPrince: Fleeting'', the webnovel sequel to the game's bad ending, Hiante gets to join the "Walking Spoiler" pile of characters simply for still being alive. [[DemBones For a given value of "alive" anyway.]]
* ''VideoGame/{{Iji}}'' has an entire ''species'' of this trope, the Komato, whose existence spoils both the true motivations of the Tasen and the second half of the game. Fortunately just mentioning their name them won't spoil anything, as there is a very early InterfaceSpoiler.
* ''VideoGame/WorldOfWarcraft''
** Drakuru in Grizzly Peaks initially seems like just another questgiver, until you discover that he's collaborating with the Lich King against the Drakkari trolls. The latter part is why most people remember and talk about him.
** Archbishop Benedictus initially seems to be nothing more than the leader of Stormwind's clergy, but it turns out that he's actually the Twilight Prophet, and one of Deathwing's highest-ranking followers.
** Y'Shaarj is quite difficult to discuss without spoiling many of the plot twists in Mists of Pandaria. He is the Old God beneath Pandaria who is the source of the Sha, having been killed long ago by the Titans, and the Mantid were created to serve him. Garrosh obtains his heart and plans to use his power against the True Horde's enemies, devastating the Vale of Eternal Blossoms in the process.
* ''VideoGame/SpecOpsTheLine''
** In a rare protagonist example, on the character sheet well over half of the character-specific tropes for Cpt. Martin Walker are spoiler-tagged out. For one thing, knowing that he's actually an [[ObliviouslyEvil unintentional]] VillainProtagonist '''massively''' changes how you view both the game and how you're playing it.
** Col. John Konrad, since for starters, he's, well, [[TheUnfought not really]] [[DeadAllAlong a villain]].
* No less than four of the love interests in ''VisualNovel/HatofulBoyfriend'' have a ton of associated spoilers for the KudzuPlot of the darker routes and backstories. Most of these come up in fandom discussion and/or sequels and manga expansions. In particular:
** Nageki Fujishiro is the ghost of a mourning dove who immolated himself five years prior to the game to prevent the virus he carries being used as a biological superweapon.
** Dr. Shuu (a false identity) works for the Hawk Party to destroy humanity out of affection for Ryouta Kawara's late father.
** Nanaki Kazuaki was "assisted in suicide" and his identity stolen by Nageki's childhood friend Hitori Uzune to seek revenge for Nageki's death.
** Yuuya Sakazaki is a TeenSuperspy working for the Dove Party.
* ''VideoGame/Bioshock1'' has pretty much anything involving Fontaine. The game presents him as being a rival to Ryan, a smuggler, and he died several years ago.
** In addition, the last name of the player character is a major spoiler. though the game does foreshadow it a bit before hand if you find several audio diaries.
* In ''VideoGame/BioShockInfinite'', reading anything online about [[TheHero Booker]], [[RealityWarper Elizabeth]], [[BigBad Father Comstock]], or [[ThoseTwoGuys the Twins]] is a good way to spoil a ''huge'' chunk of TheReveal and the ending, as the spoilers are a core part of each characters' background. Even Comstock's real NAME is a spoiler as to the final revelation.
* ''[[VideoGame/SoulSeries Soul Calibur V]]''
** The names of Alpha Patroklos and Pyrrha Omega give away that those characters will be getting alternate versions somewhere in the story.
** Any discussion of Elysium will give away that the supposed ghost of Sophitia isn't what she appears.
* ''VideoGame/TalesOfDestiny2''
** It's hard to talk about Reala without mentioning she's an ArtificialHuman.
** It's even harder to talk about anything to do with Judas and not mention [[LovableTraitor Leon]] and the fact that he dies betraying the party, though the fact that they're one and the same (barring CharacterDevelopment) isn't really meant to be a huge surprise to the player ([[LateArrivalSpoiler Provided you've played Destiny]]).
* ''VideoGame/TalesOfSymphonia''
** Even if we ignore the fact that Kratos Aurion is [[LukeIAmYourFather the main character's father]] ''and'' that [[ReallySevenHundredYearsOld he was one of the legendary heroes]], you still can't talk about his morality and motivation without spoiling ''something'', be it that he was EvilAllAlong in the first part... or was actually GoodAllAlong at the end.
** Mithos Yggdrasill's name is a spoiler, since we're familiar with two Mithoses--a young boy directly, and an ancient legendary hero from hearsay--(who are actually the same one) and also another, seemingly older, character named Yggdrasill who is the BigBad. Oh, and you're even ''allied'' with boy Mithos for a while.
** Likewise, ''everything'' about Martel. The fact that she is not a goddess is just the beginning.
* ''VideoGame/TalesOfTheAbyss'' has a weirdly literal version with Asch. His powers as the "Light of the Sacred Flame" (or remnants thereof), his reasons for joining Van, his backstory, and even his ''physical appearance'' are all spoiler-tastic. Even seeing his face or hearing his [[Creator/YuriLowenthal incredibly familiar voice]] will probably tip you off to the game's first major plot twist: Luke is Asch's replica. Sync would count for the same reasons, but due to his dramatic voice differentiation from Ion and his signature mask, and due to the fact that his motivations aren't as plot-critical, it's much harder to pick up on.
** Florian is yet another replica of Ion, as well as one who first appears after the Ion replica you know and initially assume to be the original is dead.
* ''VideoGame/TalesOfVesperia'': You can say very, very little about Captain Schwann without revealing that he's Raven. The game is also very careful not to show Schwann's face or have him speak for the same reason.
* You can't talk about Emeraude from ''VideoGame/TalesOfGraces'' without revealing that she's from another planet, goes crazy with power, inhabits a fake body and/or is directly responsible for Lambda's StartOfDarkness. Lambda is even worse for this, since you have to explain that he's a ReallySevenHundredYearsOld OmnicidalManiac {{Energy Being|s}} inhabiting either Richard's brain or Asbel's, depending on the point in the story. As such, some aspects of Richard, like the DemonicPossession, also make him kind of hard to discuss.
* In ''VideoGame/TalesOfXillia'', Maxwell, the Lord of the Spirits is a huge spoiler -- not just for the fact that he's the real [=McCoy=] and not Milla like she claims to be. He also sets the entirety of the game's plot into motion -- he separated humanity into two groups: those who can cast spirit artes and those who can't; placed those two groups into the worlds of Rieze Maxia and Elympios, respectively; created a schism so that the two worlds never meet; and also created Milla, Muzét, and the Four Great Spirits as his pawns to ensure his status quo. When a group of Elympions (Exodus) decides to invade Rieze Maxia for its resources, he directly interferes and plans to exterminate Elympios and its people; until Jude, Milla, and their allies put a stop to his schemes.
** Victor, Elle's father in ''VideoGame/TalesOfXillia2''. He initially is seen in one of the opening cutscenes, setting the game's story into motion by sending Elle away and is then seemingly shot dead by a mob of Clanspia agents, only to mysteriously recover and kill the whole lot of them. He's never seen or even mentioned again until late in the game when you travel to his alternate universe, finally meeting him in person and learning his name (Which is actually more of a title). Shortly after, the truth comes out that he's actually an older version of Ludger who gained the ultimate Corpse Shell by killing off all of the others who possessed the ability, but as a side-effect, has become a Time Factor and has little time left to live. He also happens to harbor one of the Guideposts of Canaan within him, which ultimately makes his death necessary, much to Elle's horror.
* Neyla of ''VideoGame/Sly2BandOfThieves''. She starts out as TheRival, but suddenly pulls a FaceHeelTurn on the main characters and frames her partner. She's soon revealed to be TheDragon to the game's [[DecoyProtagonist Decoy Antagonist]], but then betrays and KILLS him to steal the body of the first game's antagonist, revealing herself to be the second game's BigBad. At the end of the game, she crushes Bentley with her beak, paralyzing his legs and causing Murray to cross the DespairEventHorizon, causing the game's DownerEnding.
** For ''Videogame/SlyCooperThievesInTime'', Penelope's role in the story is a massive spoiler due to her SuddenSequelHeelSyndrome.
* From ''VideoGame/FarCry3BloodDragon'', we have the Battle Armored Dragon Assault Strike System or '''[[FunWithAcronyms B.A.D.A.S.S.]]''' for short, a Blood Dragon that you get to pilot near the end of the game. It also talks and shoots lasers out of its fucking eyes.
* ''VideoGame/RhythmThiefAndTheEmperorsTreasure''
** The only thing not a spoiler about Jean-François is that he takes care of Marie at the convent where she lives. He doesn't take any active role in the story until he assists Leonard at the Eiffel Tower as TheDragon by shooting Phantom R in the foot, taking the protagonist out of commission for a while. Jean-François then shows that he is the "Graf" that Inspector Vergier had been trying to find for several years and that he has the royal blood needed to unearth a superweapon beneath Paris, albeit missing some other necessary ingredients. This new information about him also puts his encounter with Elizabeth in a new light: Elizabeth denied being Marie's mother not because she isn't, but because Elizabeth knew what Jean-François was up to.
** Leonard Bonar himself, as he shows up right at Chapter 1, passing himself off as a resurrected UsefulNotes/NapoleonBonaparte until Phantom R finally defeats him in Chapter 9, when he admits he's a fake. This reveal then sets up subsequent reveals that the ''real'' Napoleon is TheManBehindTheMan and that Raphael's father Isaac may be a more powerful figure in this conspiracy than was previously thought.
* The Phoenix [=MkII=] from ''VideoGame/RefleX'' is a main protagonist example with the majority of its tropes being of spoiler nature. At first, it seems like a simple CoolShip with an AttackReflector and an anonymous pilot, but after it is severely damaged and its pilot killed about 7/8ths into the game, its true nature, unbeknownst to even the pilot, unfolds: the Phoenix is in fact a vessel for the ZODIAC Ophiuchus's core, which has been a major target for the Raiwat army for centuries. The Ophiuchus then causes the destruction of the other 12 ZODIAC units, making the Raiwat retreat out of fear but causing the destruction of a horrifying percentage of Earth and its population in the process. ZODIAC Ophiuchus then makes its HeroicSacrifice and seals itself along with the other 12 ZODIAC cores...only to be revived in the previous ([[BackToFront in release order]]) game ''VideoGame/{{KAMUI}}'' as the "Super KAMUI" fighter that serves as the Area 4 boss.
* It's virtually impossible to talk about [[DudeLooksLikeALady Ren]] and [[TheMentor Lindow]] A.K.A [[FinalBoss Corrosive Hannibal]] from ''VideoGame/GodsEaterBurst'' without completely spoiling the plot.
* The various endgame, bonus and twist bosses in the ''VideoGame/MegaManBattleNetwork'' series. In rough chronological order: The [[TheVirus LifeVirus]], [[PersonOfMassDestruction Bass.EXE]], [[TragicMonster Zero.EXE]], [[BackFromTheDead LifeVirus-R]], Gospel, [[EldritchAbomination Alp]][[PsychoPrototype ha]], [[UltimateLifeForm Serenade.EXE,]] and [[FusionDance BassGS.]]
* You cannot go into a discussion in ''[[VideoGame/SuperRobotWarsOriginalGeneration The Second Super Robot Wars Original Generation]]'' without mentioning that Arteil Steinbeck is really [[VideoGame/SuperRobotWarsAlpha Euzeth Gozzo]] who is the same BigBad from ''a different VideoGame/SuperRobotWars game''. And it's not even an alternate universe version of him, it's ''really him'' thanks to {{Reincarnation}} from the Cross Gate Paradigm System. [[MemeticMutation Sore mo watashi da]] indeed.
* Clare from ''VideoGame/BraveSoul'' is the answer to the game's biggest mystery. She's Rudy's "Moon Goddess," who's been [[GirlOfMyDreams appearing in Rudy's dreams for ten years]]...and she's also Shell, the dragon whose life he saved ten years ago, and his constant companion ever since. The two facts are related.
* ''Franchise/RatchetAndClank'':
** Captain Qwark has a problem with this in the first 3 games. In ''VideoGame/RatchetAndClank2002'', it's hard talking about him without revealing that he's a FakeUltimateHero who backstabs Ratchet and Clank on Umbris. In ''VideoGame/RatchetAndClankGoingCommando'', it's hard talking about him without revealing that he's the BigBad of the game. In ''VideoGame/RatchetAndClankUpYourArsenal'', it's hard talking about him without revealing that he's the one who defeated Dr. Nefarious previously, that he has a DisneyDeath on-board Nefarious' ship in the Zeldrin Starport and that he's FakingTheDead.
** In ''VideoGame/RatchetAndClankSizeMatters'', the little girl who likes to take pictures, Luna, is ultimately revealed to be the TheDragon to Otto Destruct. Not only that, she's actually revealed to be a [[NoBiologicalSex genderless]] warship/puppet built to lure Ratchet into a trap.
** Dr. Nefarious gets this for backstabbing Chairman Drek in ''VideoGame/RatchetAndClank2016''. There's not much else to say about him before the event.
* In ''VideoGame/StarCraftII'', the very fact that Samir Duran appears in the game at all, along with Alexei Stukov. Also the existence of GreaterScopeVillain Amon, since he has basically run the entire plot since Day 1, [[SpannerInTheWorks with the exception of the terrans]].
* ''VideoGame/YsSeven''
** Tia appears as a simple flower girl that Adol [[TheDulcineaEffect just has to help]]. Later you learn that she's really eldress Tialuna of the Moon Tribe, the BigBad, out to destroy the world to return it to its proper balance.
** Cruxie appears as an IllGirl that her brother Mustafa takes care of. After you gain the Fire Dragon Stone, she gets better and ''replaces'' her brother for the remainder of the game. That's right, Mustafa is really the GuestStarPartyMember.
* ''Videogame/DarkSouls'' has all the bearers of the Lord Souls, who are little more than shadows of their former selves compared to their appearance in the prologue. This is mostly pronounced with the Witch of Izalith, who got turned into the Bed of Chaos after a disastrous attempt to re-create the First Fire, and ultimately gave birth to demons all over Lordran. ''[[DownloadableContent Artorias of the Abyss]]'' adds Artorias himself, who is corrupted beyond recognition, and Manus, the BigBad of the content and the former's corrupter.
* ''VideoGame/RuleOfRose'': Despite the game's AllJustADream [[MindScrew Mind Screw-y]] nature, one thing is for certain: avoiding spoilers is near-impossible when discussing [[{{Yandere}} Wendy]], [[DeadAllAlong Joshua]] or [[CryForTheDevil Gregory]] in any kind of depth.
* ''VideoGame/HauntingGround'': Lorenzo, who spends 3/4 of the game as a MysteriousInformant, can't be talked about without giving much away (especially given that his ''first'' cutscene is a MotiveRant about how [[IHaveYouNowMyPretty he now has Fiona all to himself]]). [[CloningBlues Riccardo]] is also pretty spoiler-heavy.
* ''VideoGame/TheWitchsHouse'': Literally'' [[UpToEleven everyone]] ''in the game, due to its CruelTwistEnding and VillainProtagonist status. [[TheDogIsTheMastermind Even the cat leads to immense spoilers.]]
* Iris Zeppelin from ''VideoGame/{{Rosenkreuzstilette}}'', for being an OmnicidalManiac and the true BigBad of both games instead of the innocent girl she first appeared to be.
* For ''Videogame/{{Scratches}}'', the fact that Robin is still alive and in the mansion is the biggest PlotTwist of the game.
* Isabela Keyes becomes this big time in ''VideoGame/DeadRising3''.
* In ''VideoGame/DisneyPrincessEnchantedJourney'', BigBad Zara appears only for the final boss fight.
* ''VideoGame/FTLFasterThanLight'' has the Crystal race, which is designed to be a secret in-universe and out. However, due to the requirements for their sector and ship being so [[ThatOneSidequest infamously]] [[LuckBasedMission dependent on the RNG]], they are squarely a case of ItWasHisSled.
* ''Franchise/SilentHill'' has Alessa Gillespie, whose existence and backstory are major spoilers for the setting of [[VideoGame/SilentHill1 the first game]] and [[TomatoInTheMirror a major twist]] in [[VideoGame/SilentHill3 third game]], as well as being the ultimate cause of the series as a whole.
* ''VideoGame/TheBlackwellSeries'' has Madeline. Very little is known about her, and even ''that'' small bit of information is full of spoilers.
* ''VideoGame/SyphonFilter 2'' has Jason Chance who was working for the Agency all along..
* In the ''Franchise/AceAttorney'' series, each of the games' main antagonists count, as well as many of the murderers in each individual case. Naturally, discussing much about them would reveal that they're responsible, as well as, in some cases, [[BeneathTheMask their true personalities]].
** Probably the biggest example is Bobby Fulbright from ''Dual Destinies'', who is introduced 5-2 as the InspectorLestrade role that Gumshoe and Ema filled. Then the game drops a bombshell by revealing that he's actually Phantom, an emotionless agent who murdered Fulbright prior to the story's events and stole his identity, as well the killer of both Clay Terran and Metis Cykes. This is revealed ''very'' late into the game's events, but is a massive twist, especially since Fulbright is one of the last characters one would suspect as the BigBad given his role and much of the {{Foreshadowing}} towards the revelation is very subtle.
** Matt Engarde from ''Justice for All'' is a very special case as his true personality is denoted by his TwoFaced scars, hidden by PeekABangs until Phoenix Wright gathers enough evidence to reveal his secret. Therefore, anyone foolish enough to Google his name before finishing the game will find the majority of image results to show Engarde with his obviously evil scars and SlasherSmile.
* ''Franchise/FiveNightsAtFreddys'' has many spoiler-heavy characters, as each of the four games have a rather hidden and complex backstory:
** Golden Freddy, Shadow Freddy and Shadow Bonnie, the former from the first game and the latter two from the sequel. Knowing even a little bit about them can ruin the surprise on the rare chance you run into them, and the former slowly comes into importance in the backstory.
** The Purple Man and the Puppet, both debuting in [[Videogame/FiveNightsAtFreddys2 the sequel]], are incredibly important characters in the franchise's backstory. In fact, it's nearly impossible to not spoil the former since he ''only'' shows up in the backstory.
** Springtrap in the third game is a massive one. It's hard to describe it without giving away the fact that there's a human corpse inside the suit. However, thanks to [[http://vignette3.wikia.nocookie.net/fnaf/images/8/88/Springtrap_Rare_3.jpg/revision/latest?cb=20150319192901&path-prefix=pl a few randomly-occurring boot-up screens]], [[ItWasHisSled a good portion of the fanbase knows this already]].
** Both the child protagonist and his BigBrotherBully in ''Videogame/FiveNightsAtFreddys4'' are filled to the brim with spoilers. Without giving too much away, let's just say that they ''[[AmbiguousTimePeriod might]]'' have a very important connection to the franchise's NoodleIncident.
** Fredbear from the same game has more than one [[TheReveal reveal]] to be had, both of which make it harder to explain him without giving them away.
** Circus Baby from ''[[Videogame/FiveNightsAtFreddysSisterLocation Sister Location]]'' is more than players may assume her to be, making discussion of her role difficult. From the same game is Ennard, and talking about it is flat-out impossible without giving away a few major twists revealed on Night Five. And as of the Custom Night update, the true identity of protagonist Eggs Benedict is a massive twist on the franchise's lore.
* The Judge in ''VideoGame/{{Poacher}}''. He's present from the beginning as the game's narrator, but knowing his ''name'', let alone who he really is, is a massive spoiler for the secret ending.
* ''VideoGame/DragonFable'': How do you mention the Mysterious Stranger without revealing that he was the true mastermind behind everything that happened over the entire first chapter of the game? You don't. How do you talk about Wargoth without revealing that the one you fight throughout the second chapter is actually Warlic's demonic half that split from his human half and took form after Warlic [[PhlebotinumOverload overloaded his mana pool]], by creating a light sheild to protect Falconreach from the Mysterious Stranger? You don't. How do you mention Jannia, the ArcVillain of the third chapter, without addressing how she used to be a friend of both Warlic and Xan until she got frozen in everlasting ice during the same duel that turned Xan into the insane pyromancer he is, and that both of them lost their minds due to spending at least several decades trapped in their own mutually-exclusive magical prisons, immortal, but totally awake and aware of the passage of time? [[RuleOfThree You don't]].
* Jergingha in ''VideoGame/TheWonderful101'', the leader of the GEATHJERK, goes un-mentioned until the fifth (of nine) chapter.
* Erim, the Sinistral of Death, in the ''VideoGame/{{Lufia}}'' series. She appears in different mortal guises throughout the series, and her role varies from game to game. One game has her unknowing reincarnation, one game has her observing and manipulating the heroes, and one game has her work ''with'' the heroes to try to stop the Sinistrals for good. Needless to say, it's very difficult to describe Erim's role in the plots without revealing who she is in each game.
* Gamall from ''VideoGame/ThiefDeadlyShadows'' once it's revealed she's been DeadAllAlong and the entity known as The Hag [[DeadPersonImpersonation has been pretending to be her]].
* Iovara from ''VideoGame/PillarsOfEternity''. She reveals that the gods are artificial constructs, and that there is no deeper meaning to the universe, the cycle of death and resurrection, et cetera. It was for revealing all this that Iovara was tortured to death and her soul imprisoned by those who believed the gods were the only way to ensure peace and stability in the world. [[AntiNihilist She takes the world's meaninglessness well]], but the player character has a number of options to deal with the revelation, including deciding TheseAreThingsManWasNotMeantToKnow and telling nobody else.
* ''VideoGame/MegaManV'' has Sunstar, which no mention of whatsoever is brought up until after you've defeated Dr. Wily. He turns out to be the ultimate Stardroid and becomes the FinalBoss of the game.
* ''VideoGame/MegaManUnlimited'' has [[Franchise/MegaManX Zero's]] prototype form, who only shows up in the final Wily Stage and is a PostFinalBoss and HopelessBossFight.
* In ''VideoGame/MegaManRockForce'', Justice Man is revealed to be the one behind the events of the game, having decided to ensure freedom for him and all robots by starting a rebellion against humans and capturing the Rock Force.
* For ''VideoGame/MegaManRevolution'', we have Dr. Remir, who is revealed to be the true BigBad of the game and actually hijacks the plot ''from'' Dr. Wily! In addition, he's also an alien whose race basically created the Evil Energy.
* ''VideoGame/{{Splatoon}}'':
** DJ Octavio is an unusual example in that he's not a Walking Spoiler due to plot reasons (though he has a few surprises). Rather, his characterization and boss fight are so unique and fun that players are very reluctant to give away details to unknowing players. None of this is shown prior to his battle (which is the FinalBoss of the single-player story mode), which adds on to the trope.
** Judd the Cat is a straight example, as his backstory is entirely tied to the spoiler-heavy history of the ''Splatoon'' world, which is not revealed until close to the end of the single-player mode.
* Given [[MindScrew the ways that]] [[AnachronicOrder the plots work]] in ''VideoGame/HotlineMiami'' and [[Videogame/HotlineMiami2WrongNumber its sequel]], most characters and their goals are quite spoiler-heavy:
** Jacket, in a main character variation, is one because of the revelation that he has been in a ConvenientComa for 3/4 of the game, and that most of the MindScrew that happens during it is a result of his coma dream blending together various memories of his.
** The Biker, who is unexpectedly PromotedToPlayable after the player ''thinks'' that the plot has been resolved, and actually goes out of the way to resolve a handful of plotlines at the end. He also returns in the sequel (albeit in a possibly non-canon EasterEgg), which spoils the fact that he survives his fight with Jacket in Neighbors.
** Richter, the one who shoots Jacket's girlfriend, becomes this ''twice''; Not only does he become the cause of Jacket's coma by way of YouHaveOutlivedYourUsefulness, but his role in the second game ([[CuttingOffTheBranches and the fact that he is alive during the 1990s]] as well) shows that he is much more sympathetic of a character than the first game led players to believe.
** The Janitors, who turn out to be the duo who run 50 Blessings, the organization that the above three work for, in order to take out TheMafiya. The fact that they [[CuttingOffTheBranches are also alive in Wrong Number]] counts as well.
** Manny, The Detective, who turns out to be a AttentionWhore RabidCop, instead of an UnscrupulousHero CowboyCop.
** The Solider/Beard, who [[NewJobAsThePlotDemands ran the various establishments that Jacket went to between levels]] in the first game. Not only was he DeadAllAlong before Hotline Miami began, but it turns out his death was the reason that [[RoaringRampageofRevenge Jacket chose to work for 50 Blessings in the first place]].
** The [[TheSquad Ghost]] [[TheDreaded Wolves]]' unnamed commanding officer, whose FreakOut in one of The Soldier's later missions heavily implies that he's the person who originally founded 50 Blessings.
** The Son, whilst not having that many backstory-related spoilers (aside from being [[MeaningfulName the son]] of the first game's FinalBoss), becomes this due to the fact that his death is what most likely is what causes the SuddenDownerEnding.
* ''VideoGame/AkibasTrip'' has Rin, a local pop idol who turns out to be Shizuku's younger sister and like her, a [[OurVampiresAreDifferent Nighteater]] investigating Daishihon Pharmecuticals for their connection to the Synthisters.
** Soga also qualifies, due to being the BigBad as well as Shizuku and Rin's older brother and the one helping Zenya Amo and Koma Sakaguchi.
* The Mother from ''VideoGame/LaMulana'' is impossible to talk about much without going into spoilers about just who she is and her importance to the plot. In fact, the opening cinematic even does its share of spoiling. Some might also argue the existence of Hell Temple as well as the "Treasure That Must Not Be Seen," though those are pretty squarely in ItWasHisSled territory at this point.
* In ''VideoGame/TimeCrisis II'', Robert Baxter is a run-of-the-mill VSSE agent and the player 2 character. In ''Time Crisis 5'', released over fifteen years later, he pulls a big-time FaceHeelTurn and becomes the BigBad, something you don't learn until late into the game. This reveal is quite shocking for series veterans who bother to follow the {{Excuse Plot}}s.
* ''Videogame/{{Disgaea}}'':
** The mere existence of real Overlord Zenon spoils the first half of ''VideoGame/Disgaea2CursedMemories''. The identity of this person (revealed in the final five minutes AFTER the final boss) spoils the entire game.
** Geoffrey is Mao's incredibly efficient butler in ''VideoGame/Disgaea3AbsenceOfJustice''. Anything beyond that description will turn the game on its head.
** Nemo of ''VideoGame/Disgaea4APromiseUnforgotten'' is a mysterious figure working behind the scenes in the Corruptment. To say anymore about him would spoil a huge chunk of the game.
** Xenolith from ''VideoGame/DisgaeaDimension2''. Even his ''character design'' is a pseudo spoiler, since his resemblance to Etna exposes a major plot twist.
** In ''VideoGame/{{Disgaea 5}}'', the only things you can talk about regarding Liezerota without spoiling many critical plot twists are her leoine features and that she's a {{Nice G|uy}}irl. She's that much of a spoiler that Creator/NipponIchi accidentally spoiled one of the game's major twists several months before the release date with a seemingly harmless update to the game's website.
* Given the amount of HiddenDepths its characters have, almost '''all''' major ''VideoGame/{{Undertale}}'' characters have some massive spoilers, which it's barely possible not to mention, but the biggest offenders are:
** Asgore, whose mere appearance is spoileriffic, let alone his personality and actions.
** Both Asriel and the Fallen Child, who, just by existing, mark a turn for either [[GoldenEnding the best]] or [[DownerEnding the worst]].
** Sans, for his role in the No Mercy route and the real reason for his laziness.
** The Amalgamates (and by extension, the True Lab), for their existence being kept a secret (for good reason) and for being heavily involved in one of the characters' backstories and motives.
** Flowey, due to his backstory, true identity, and the nature of his powers.
** W.D. Gaster, who is only mentioned in the spoileriffic True Lab and is involved in a mystery so secret and enigmatic it's [[DummiedOut not even in the game]]. Then again, given his nature, one is extremely unlikely to learn about him without spoiling his existence for themselves unless they either have a field day with their save file or, in the updated version, get lucky with the RandomNumberGod.
** Even the ''player character'' is one. Not Frisk, but ''you'' -- the twist is that the two are entirely separate entities.
** The six human souls are instrumental to defeating the Neutral route's final boss. Problem is, that boss is built around trying to make you feel hopeless, so if you know how to beat him going in, the effect is ruined.
** Let's put it this way: there's [[Characters/UndertaleSpoilerCharacters an entire page with no spoiler tags dedicated to the game's most spoilerrific characters]].
* ''VideoGame/ThreeTheHardWay'' has Anderson, a travelling monk who joined the party seeking for new challenges. That latter claim is a lie, but saying anything about him beyond those facts is going to spoil many important plot points.
* ''VideoGame/ValkyriaChronicles''
** For ''VideoGame/ValkyriaChronicles2'', there's Dirk, one of the members of House Gassenarl (the villains of the game) and also the [[SuperPrototype first Artificial Valkyrur]]. After the attack of Lanseal, he's revealed to actually be Leon Hardins, Avan's brother, who was said to have been killed during a secret mission.
** There's also Baldren, another member of House Gassenarl, who is seen as TheDragon to his father Gilbert and serves as one of the bosses in the game alongside Dirk and Audrey. Then in September, after his father decides to give Gallia to TheFederation and stop the Darscen purges, Baldren snaps, [[TheStarscream kills his father]], takes over as leader of the Gallia Revolutionary Army, and during the game's climax, becomes the [[OneWingedAngel perfect Artificial Valkyria]] and the FinalBoss.
** Headmaster Laurence Kluivert is also this, when it turns out that he was part of the Asgardian Council, helped with Project Valhalla, which involved the research and creation of Artificial Valkyria, and is thus partially responsible for the loss of Leon Hardins' sanity/humanity and also the death of Juliana Everhart.
** In the first game, there's a second character named Isara Gunther seen during the post-credits scene. She's Welkin and Alicia's daughter, spoiling that they get married and [[BabiesEverAfter have a child together]] after the game's end.
* ''VideoGame/ShovelKnight'':
** The Enchantress, who's actually an evil spirit possessing the body of Shovel Knight's long lost friend, Shield Knight.
** Directly tying into the above is Black Knight, whose true motive behind his loyalty to The Enchantress is protecting Shield Knight.
* ''VideoGame/NuclearThrone'' features the titular throne itself, which is the MacGuffin the mutants are searching for. The twist is that the Throne is ''not'' controlled by the skeleton sitting on it, but is in fact a sentient object which serves as the game's FinalBoss. The [[OneWingedAngel Throne II]] fight brings in even more spoilers, as it reveals that the Throne is some sort of EldritchAbomination and may be related to the purple portals that you've been using for the entire game.
* ''[[Webcomic/TeamFortress2 Team Fortress Comics]]'' (supplementary comics for ''VideoGame/TeamFortress2''):
** Bill-Bel and Lar-Nah not only dig into the backstory of one of the nine mercenaries/classes, but their actions kickstart the TraumaCongaLine Miss Pauling's team goes through at the end of ''Blood in the Water'' and all throughout ''Old Wounds''.
** The fact that the mercenaries/classes from ''VideoGame/TeamFortressClassic'' play a big role in the story is already a huge twist, but [[TheStarscream their role]] in ''Old Wounds'' is what really drives the point home.
** The Medic's supposed FaceHeelTurn was also a huge twist before ''Old Wounds'' came out, but said comic reveals that he still cares about his team.
* For ''VideoGame/FairyFencerF'', there's Sherman, a handsome nice guy that believes in justice, wishes to bring peace to the world, and joins Fang and his group at one point. However, he later attacks Tiara shortly before the [[TimeTravel singularity]] happens and in the second timeline, he shows an evil side, kills the president of the Dorfa Corporation, [[KlingonPromotion taking his place]], plans on sacrificing Tiara in order to awaken the [[GodOfEvil Vile God]] so that he can create a new world of peace, is revealed to be the one that killed Tiara in the first timeline, and finally [[OneWingedAngel merges with the Vile God]] and becomes the FinalBoss.
* For ''VideoGame/ToadetteStrikes'', we have not a character, but a ''whole world'' as this. The world in question happens to be Subcon from ''VideoGame/SuperMarioBros2'', except having gone to hell and falling apart due to the dream virus that [[BigBad Kammy Koopa]] has been using to put the Toads in eternal sleep.
** There's also Reckloo, the pair of eyes seen in shadows at various points in the game. He turns out to be the GreaterScopeVillain and TrueFinalBoss ([[AmbiguousSituation and possibly Mario 2's main villain]]).
* In ''VideoGame/DustAnElysianTail'', we have the protagonist himself, Dust, who due to him being an AmnesiacHero on a QuestForIdentity, has a massive amount of spoilers regarding who he really is and what's in his past.
* At the end of the Soviet campaign in ''VideoGame/CommandAndConquerRedAlert'', Stalin's secretary is revealed to be none other than the BigBad of the ''VideoGame/CommandAndConquerTiberianSeries'', Kane.
* Just about every character aside from the six main animatronics in ''VideoGame/{{POPGOES}}'' has a secret to hide. Special mention goes to Strings, one of the other animatronics, who is actually the playable character.
* Thorn in ''VideoGame/{{Caligula}}'' is hard to talk about without getting into heavy endgame spoilers. They at first appear to be Shougo's friend that he got killed (which is quite a spoiler in and of itself) come BackFromTheDead, but turns out to actually be another character entirely.
* Although ''VideoGame/RaymanOrigins'' isn't very concerned with having a plot, it's still difficult to read about the Magician without spoiling the character's significance to the game, as well as its biggest twist. ''VideoGame/RaymanLegends'' makes it even more difficult since [[LateArrivalSpoiler it assumes you know what his deal is by then]].
* Since the plot revolves around trying to understand and defeat the monsters of ''VideoGame/{{Evolve}}'', which initially appear to be nothing more than another dangerous species on [[DeathWorld Shear]], any discussion that involves more detail than that carries major spoilers. Unusually, the biggest spoilers will occur in discussions instead of playing the game, as the expiration of TRS's contract and 2K subsequent cessation of support means TheReveal never got to happen in-game but was instead revealed by the developers in the last few hours when they had creative control.
* In ''VideoGame/StardewValley'', we have Krobus and the Dwarf. Seeing as they're meant to be {{secret character}}s that even have their own {{secret shop}}s, simply mentioning their names can prove to be spoilers.
* ''VideoGame/MonsterHunter 4'' has the Shagaru Magala, the mature form of the Gore Magala who's been hounding you throughout the entire game, infecting some monsters with the Frenzy Virus while it's at it.
* ''VideoGame/Bayonetta2'' has the BigBad Loptr, who masterminded the events of the game.
* ''VideoGame/BanjoKazooie'' has [[DeusExMachina The Mighty Jinjonator]] deliver the final blow to the final boss.
* Anthony of ''VideoGame/EternalDarkness'' isn't a spoiler in himself, and neither is his death; after all, he lived in the year 814, and the game's present day is 2000. What ''is'' a spoiler is that he technically survives his chapter as an [[ZombifyTheLiving undead abomination]] that must be finally put to rest by the next chronological visit to the cathedral, Paul Luther, as a miniboss. A full ''670'' years later.
* Sirius in ''VideoGame/Bomberman64'' initially appears as a friendly ally to Bomberman. After you collect all 100 Gold Cards, it's revealed that Sirius was the original owner of the Omni Cube and had trapped even more galaxies in there than Altair, as he had a proper knowledge on how to use the cube. Sirius makes up lies to Bomberman that Altair had killed his family; however these are false and he uses them to get Bomberman on his side. After he reveals his true intentions to Bomberman, he callously throws him away and nearly destroys Planet Bomber.
----
** When you finally meet President Eden face-to-face in ''VideoGame/Fallout3'', you were probably not expecting him to be an A.I.
** It is very hard to talk about Shaun from ''VideoGame/Fallout4'' without revealing that he is the leader of the Institute.
*** Also, from the Nuka World DLC of that game, the fact that John-Caleb Bradberton is alive with his [[BrainInAJar head in the jar]] makes him a huge WalkingSpoiler.
* ''[[VideoGame/{{Onmyoji}} Onmyōji]]'' has [[BigBad Kuro Seimei]]. It's pretty much a spoiler to mention that this guy ''exists'' in the first place without also revealing his [[EvilCounterpart inherent]] [[LiteralSplitPersonality connection]] to Seimei. He's [[SirNotAppearingInThisTrailer never mentioned]] in any of the game's promo material, and Creator/NoriakiSugiyama is only ever credited as voicing Abe no Seimei ''and nobody else'' in these materials.
** And then there is [[GreaterScopeVillain Yamata-no-orochi]]. Sure, you can talk about him as the PinataEnemy in the ''mitama'' dungeons, but mentioning any of his involvements with the plot reveals his being an even bigger threat than Kuro Seimei, [[BitchInSheepsClothing Yaobikuni]]'s [[TheDragon working for him]] [[EvilAllAlong all along]] and the Sword of Kusanagi's being a ChekhovsGun necessary to destroy him once and for all.
** If you try to talk about Kairaishi's role in the story, you'll find that there's nothing much to speak of beside the fact that she ''has a Kusanagi fragment in her chest''.
* ''Franchise/{{Pokemon}}''
** In ''VideoGame/PokemonBlackAndWhite'', N has one of the largest character pages of any character in the ''Pokémon'' games. It is at least 50% spoilered. [[TheManBehindTheMan Ghetsis]] is even more so, with at least 65% of his page spoilered before ''VideoGame/PokemonBlack2AndWhite2'' came out.
** ''VideoGame/PokemonXAndY'' brings us Lysandre and AZ. While the game makes few attempts to hide the fact that Lysandre is the leader of Team Flare, it does drop a bombshell regarding AZ being a 3,000 year old immortal who built The Ultimate Weapon.
** ''VideoGame/PokemonSunAndMoon'' has the entirety of the Aether Foundation, which turn out to not only be the game's [[EvilAllAlong second villainous team]] but the main villains of the game with Team Skull assisting them in getting Cosmog back. Lillie and Gladion also qualify due to their connection to [[BigBad Lusamine]]. Talking about UB-01 is also a little spoilerific, and Cosmog is nigh-on impossible to discuss without spoiling TheReveal of its evolutions.
** Blake Hall, the president of Altru Inc., in ''[[VideoGame/PokemonRanger Pokemon Ranger: Shadows of Almia]]'' is this, as he turns out to be [[BigBad the leader]] of Team Dim Sun.
** Purple Eyes from ''[[VideoGame/PokemonRanger Pokemon Ranger: Guardian Signs]]''. He comes in after the supposed ending as the new leader, and directly leads into the next villain. Also, all members of the Societea.
** Darkrai from the [[VideoGame/PokemonMysteryDungeonExplorers second set]] of ''VideoGame/PokemonMysteryDungeon'' games is an example of TheManBehindTheMan who appears [[YourPrincessIsInAnotherCastle after you think the story is over]].
*** From the same game[[OneGameForThePriceOfTwo (s)]], Grovyle and Dusknoir. Neither is what they appear to be at first glance, and spoiling Grovyle's identity also carries major reveals for the player character with it.
** Hydreigon and Munna in ''VideoGame/PokemonMysteryDungeonGatesToInfinity''. The former appears to be ObviouslyEvil initially, but turns out to be the BigGood, while the latter appears to be a DamselInDistress, but ends up being a DecoyDamsel who's plotting to eliminate the hero.
*** The Bittercold, being an EldritchAbomination that's a manifestation of the Pokemon world's misery, the true BigBad of the plot, and the motive behind Kyurem and Munna's actions.
** Bringing up Nuzleaf in ''VideoGame/PokemonSuperMysteryDungeon'' can easily spoil most of the game considering his status as TheMole thanks to Dark Matter, who due to being an OutsideContextProblem similar to Bittercold, is also a walking spoiler.
*** Talking about Mew will inevitably spoil his status as a replacement for the partner character and the ending's MetaTwist.
* ''VideoGame/RuneScape''
** How do you describe [[HarmlessVillain Wizard Grayzag]] without giving away that he TookALevelInBadass, killed a bunch of Void Knights and becomes the BigBad for the quest series?
** Kharshai's entire character pretty much bases on the fact that he is actually in disguise as Koschei the Deathless.
* In ''VideoGame/DragonAgeOrigins'', every mention of major villain Teyrn Loghain Mac Tir as a possible PlayerParty member is always covered in spoiler tags because the very fact that he can become one is a major plot twist. When that is not possible, he is conventionally referred to as "Secret Companion".
** Corypheus manages to be a Walking Spoiler two games in a row, being the secret BigBad of both ''VideoGame/DragonAgeII'''s ''Legacy'' DLC and ''VideoGame/DragonAgeInquisition''.
** Thom Rainier from ''VideoGame/DragonAgeInquisition'', a mercenary who became TheAtoner after [[MyGreatestFailure his role in an atrocity]]...by [[DeadPersonImpersonation taking on the identity of the deceased Warden-Constable Blackwall]].
** After TheStinger, it became very difficult to discuss Solas in a meaningful capacity without also bringing up the fact that [[GodWasMyCopilot he's actually Fen'Harel,]] [[TricksterArchetype the elven trickster god.]]
* The infamous Hidden Fun Stuff from ''VideoGame/DwarfFortress''. It's an UnusualEuphemism for Hell and its resident horde of demons, which will invade your fortress if you dig too deep. Many players use circus-themed euphemisms in reference to it, such as calling the demons 'clowns', and referring to the adamantine metal that usually stands between the surface world and 'the circus' as 'cotton candy'.
* The 16th playable character in ''VideoGame/TheReconstruction'', Tezkhra, is first heard of as the god worshiped by certain groups of shra.
* ''Franchise/MassEffect'':
** Sovereign as [[TheManBehindTheMan the true]] BigBad of ''VideoGame/MassEffect1'' is treated as extremely sensitive. [[AbusivePrecursors The Reapers]] in general are not considered spoiler information, but ''he'' is.
** Legion from ''VideoGame/MassEffect2'', not only as a geth ''protagonist'' (as they'd been the major enemy in the previous game), but also that [[PronounTrouble they]] can join the player's squad.
** Morinth from the same game. You can recruit her in place of her mother, Samara, if you choose to betray the latter during the climax of her loyalty mission, though to get the option to do so you need a sufficient Paragon or Renegade score. Even the fact that the Ardat-Yakshi is Samara's daughter is a twist.
** The Human Reaper, final boss of ''[=ME2=]'', whose existence has the entire Collector plot revolving around it, as well as being a ''huge'' reveal for the motivations of the Reapers.
** Javik in ''VideoGame/MassEffect3'', since his very existence spoils the fact that not all the Protheans are dead, since the first game had the few survivors' life pods run out of power while on Ilos, and by the time Shepard and company reach it they've all been powered down. Also ties into TheReveal in ''Mass Effect 2'' that the Collectors are actually indoctrinated Protheans.
** The Catalyst from the same game, since he literally only appears in the last scene of the game. This also spoils that he is an individual rather than an object.
** The creatures from the ''Leviathan'' DLC of the same game, since they're the last remnants of the first race to be turned into a Reaper and give an epically spoileriffic InfoDump.
** The ''Citadel'' DLC of the same game has its ArcVillain who turns out to be a clone of Commander Shepard. There's also Maya Brooks, who turns out to be EvilAllAlong and TheDragon to the Clone Shepard.
* ''VideoGame/{{Xenoblade}}'':
** Fiora is by far the most spoiler-heavy character in the game, considering she was implied to have died a few hours in but got turned into a RobotGirl instead. She's so spoileriffic that it is a common courtesy on forums and this wiki to refer to her by the euphemistic FanNickname "Seven." That said, her trophy in ''VideoGame/SuperSmashBros for Wii U'' and her later cameo in ''VideoGame/ProjectXZone2'' have [[LateArrivalSpoiler no such issues]].
** Metal Face's true identity is treated as a big reveal, as is Jade Face's.
** Dickson claims that he's "full of surprises." He's '''not''' joking, especially during the Mechonis Core events, when he shoots Shulk and reveals himself as TheDragon and later a member of the extinct Giant race.
** Describing Alvis as anything beyond "mysterious guy who teaches Shulk how to use the Monado" will reveal something big, mainly due to his actions after Mechonis Core and his role in [[GainaxEnding the ending]].
** Zanza, who seemed to be a semi-important character introduced and swiftly killed off at the end of the Prison Island storyline. Turns out that ''technically'' wasn't even him, and not only is he the BigBad and the FinalBoss, but one of the two gods of the world and the Monado itself!
* ''VideoGame/XenobladeChroniclesX'':
** Lao is, starting with Chapter 9, impossible to talk about spoiler-free due to his FaceHeelTurn, [[FreudianExcuse his motives for doing so]], and becoming the FinalBoss.
** Elma is the subject of a massive Reveal in the last few chapters about her true nature and her role in the overall plot.
** A few minor, unassuming [=NPCs=] who eventually become the antagonists of missions fall into this, especially Powell, Alex, Ornella, and Justin.
** The existence of the Tree Clan Prone is largely kept secret until a good way through the game ([[InterfaceSpoiler unless you take a peek at the achievements list]]), at which point they are involved in many missions thereafter.
* ''VideoGame/TheLegendOfHeroesTrailsOfColdSteel'' has several, both from the first game and the sequel. Note that all [[WalkingSpoiler Walking Spoilers]] for the first game become {{Late Arrival Spoiler}}s in the sequel (to the point where watching the trailer for the sequel spoils almost the entire first game).
** From the first game:
*** Crow Ambrust. He's a student at Thors a year above Rean who loves gambling. And this is all you can say about him without major spoilers.
*** Vita Clotilde and Misty. Them being the same person is the ''least'' of it. Vita is presented as such a minor, irrelevant character that the fact she even is a WalkingSpoiler [[TheDogWasTheMastermind is itself a huge spoiler.]]
*** Emma and Celine. It's clear there's ''something'' odd about Emma right from the start, but her and Celine's true purpose is only revealed at the very end of the game.
** From the sequel:
*** Rufus Albarea. Starts off as just Jusis' AloofBigBrother, but he turns out to be central to the single biggest plot twist in a game already full of them. As this reveal puts all his previous actions in a totally new light, it's difficult to talk about him without spoiling anything.
*** Giliath Osborne. You know you're one of these when you manage to derail the villains' plans simply by ''showing up''.
* The above game's prequel, ''VideoGame/ZeroNoKiseki'' also has quite a few:
** Joachim Gunther. Introduced as a friendly doctor at St. Ursula. Turns out he's [[BitchInSheepsClothing anything but]]: He's actually one of the few remaining members of the D∴G Cult, which kidnapped children and performed various painful experiments on them.
** Ian Grimwood, Crossbell's public lawyer. He's presented as such a minor character that his role in the sequel is a huge twist: He's the one who murdered [[TheHero Lloyd's]] brother.
* Wheatley turning out to be an antagonist in ''VideoGame/{{Portal 2}}'' is meant to be a big twist. Thus, spoilers. Everywhere.
** Cave Johnson being a character in the game, albeit [[PosthumousCharacter posthumously]], as he is only "present" in the ruins of the old Aperture labs that are the setting for the second Act. Which for extra points are only visited after aforementioned Wheatley becomes the antagonist.
** Similarly, it's hard to talk about Caroline without revealing that [=GLaDOS=] is the result of the aforementioned Cave Johnson [[BrainUploading uploading her into the database without her consent]].
* ''VideoGame/BlazBlue'': One for every game just about, and almost always revealed in the game's GoldenEnding to boot.
** ''Calamity Trigger'':
*** It's nigh-impossible to talk about Hakumen without revealing that he is [[TheRival Jin Kisaragi]] from a previous iteration of the time loop.
*** The mild-mannered pacifist Captain Hazama was one himself, being the vessel for one of the BigBadEnsemble, Yuuki Terumi.
** ''Continuum Shift'':
** Saya appears to be Ragna and Jin's missing little sister. Turns out that she's actually TheManBehindTheMan and the head of the organization the two have been fighting against the whole time.
*** Mu-12 was one as well, being Noel Vermillion's SuperpoweredEvilSide and revealing that she was created just like her sister units and being a clone of the aformentioned Saya.
** ''Chronophantasma'':
*** Izayoi for ''Chronophantasma'' continues the tradition of each game having one such character introduced. Specifically, it's the true form of the weapon that Tsubaki Yayoi has been using throughout the entire series.
** ''Central Fiction'':
*** Susanoo is Yuuki Terumi's OneWingedAngel form, and reveals his true identity as the original consciousness of the Susanoo Unit. Terumi also slayed Hakumen to achieve this form AND was the one who enabled humanity to find the Susanoo Unit and thereby make contact with the Master Unit kickstarting the events the entire series to begin with.
*** The game's title refers to Ragna himself, being the "dream observed by god" or more simply, the primary reason the time loops keep occurring. The Master Unit would constantly reset and change the world whenever Ragna died and so to ensure the world moves forward without interference, Ragna [[{{Retgone}} removes himself from the world as well as any memory that he ever existed.]]
* Yomiel, the mysterious BigBad of ''VideoGame/GhostTrick''. When he shows up, the game pretty much heads into one MindScrew and PlotTwist after another. For that matter, Ray and Sissel (the player character himself) also count since the game is about finding out [[AmnesiacHero what his identity was before he was killed]].
* ''VideoGame/BatmanArkhamCity'':
** Clayface, who for those familiar with [[VoluntaryShapeshifting his powers]] merely mentioning his name gives a big clue to a major twist just before the end of the game. Overlaps with InterfaceSpoiler as looking at The Joker with Batman's Detective Vision shows he has no bones or internal organs.
** Simply mentioning Hush spoils the ending to the "Identity Theft" sidequest. Although, those familiar with the character can already guess who is responsible.
** Discussing anything about the Mad Hatter spoils a (admittedly very short) sidequest as well as the source for a lot of Hugo Strange's influence and resources.
* Joshua, and, to a lesser extent, Hanekoma in ''VideoGame/TheWorldEndsWithYou''. Kitaniji too, as you don't really learn his real role in the plot until the very end. And Eri to an extent, as merely ''describing her appearance'' can spoil a significant plot twist regarding Shiki.
* Many villains from ''Franchise/{{Kirby}}'' end up as this trope, due to most of them being [[VileVillainSaccharineShow quite darker than the rest of the franchise]]:
** Magolor from ''[[VideoGame/KirbysReturntoDreamLand Return to Dream Land]]'' and Marx from ''VideoGame/KirbySuperStar'' are both notable for betraying Kirby and his friends by using them as {{Unwitting Pawn}}s.
** Queen Sectonia from ''VideoGame/KirbyTripleDeluxe'' comes along with almost no foreshadowing whatsoever, and is quite notable for being one of the only cases of LightIsNotGood in the franchise.
** Zero and his undead form, appearing in ''VideoGame/KirbysDreamland3'' and ''VideoGame/Kirby64TheCrystalShards'' respectively, come off as a major surprise due to the fact that both of them [[FamilyUnfriendlyViolence bleed in what's supposed to be a family-friendly franchise]].
** The true form of Star Dream from ''VideoGame/KirbyPlanetRobobot'' is arguably the ''largest'' plot twist in the entire franchise's history, as it ties back to [[VideoGame/KirbySuperStar one of the franchise's oldest games]] in a very unexpected way.
*** President Haltmann's personal motives are kept tight-lipped until much later in the game, and [[TheWoobie for good reason]].
* Normally, Kor from ''VideoGame/JakIIRenegade'' would just be your typical old man. Most of his tropes come from the fact that he's really [[BigBad the Metal Head Leader]] in disguise. What's particularly ''clever'' about this one is that Kor acts as TheMentor to The Kid and a CoolOldGuy towards Jak and Daxter. Most players likely won't bat an eye at some of the spoiler-tags because they might ''assume'' he suffers MentorOccupationalHazard (justifying his absence from later games), and even then they might be misled into thinking that the secrets he's obviously hiding are considerably more benevolent than they turn out to be.
* ''VideoGame/KnightsOfTheOldRepublic'':
** Revan being the PlayerCharacter of the first game is a major plot twist, causing the former Dark Lord of the Sith to become the main source of spoilers of the game. This makes the ''first sentence'' of the plot synopsis for the game on Wookieepedia (unless it has been changed by the time you read this) a huge spoiler for TheReveal more than halfway down the plot.
** The second game has Kreia. She casually mentions early on she used to be a Sith Lord, and that's the ''least'' of the spoilers regarding her.
* ''VideoGame/StarWarsTheOldRepublic'':
** It's hard to mention much about Master Syo Bakarn without bringing up that he's a [[ManchurianAgent Child of the Emperor]] and the Jedi Consular's final boss.
** Likewise, just try talking about the Jedi Knight's TokenEvilTeammate Lord Scourge ''without'' using spoilers.
** The Smuggler storyline has Darmas Pollaran, who is revealed later in the story to be an Imperial agent who has been manipulating the Smuggler to do the Voidwolf's bidding throughout their career as a Republic privateer.
** It's difficult to discuss much about more than a few characters from the Imperial Agent storyline without spoiling the various plot twists, though the biggest examples would be Darth Jadus, who turns out to be the BigBad of the Agent story's Act 1, and Hunter, who is not only the final boss of the Agent storyline, but also revealed to be a woman.
** With Revan ''and'' the Exile making final performances in the game, there are a couple of flashpoints that are nothing but spoiler tags.
* ''VideoGame/KidIcarusUprising''
** After you defeat Medusa and the fake credits roll, [[TheManBehindTheMan the true villain, Hades]], comes in and takes over the Underworld Army. And since we were led to believe that Medusa was the villain with no hints of Hades being in the game…
** To a lesser extent, pretty much everyone who is introduced after Chapter 9, which is built to look as much like the final dungeon as possible. The Chaos Kin is an especially strong example, since talking about it not only spoils that the game goes on after Chapter 9, but it is also likely to reveal much about the Chaos Kin's [[WhamEpisode story arc]], particularly Pit being trapped in a ring for three years and Palutena turning evil.
* The Golden Spider/Chakravartin from ''VideoGame/AsurasWrath'', seeing he is the true BigBad and the {{god}} of his universe, having manipulated all the events in the game for his own interest. [[note]]Before the character page was redone with unmarked spoilers, only one trope applying to him was unspoiled at best.[[/note]]
* ''Videogame/DeadlyPremonition''
** Forrest Kaysen. Many spoilers are required to conceal that the fat, jolly tree salesman is not only the BigBad of the game, but a HumanoidAbomination to boot.
** George gets quite a few spoilers too, by virtue of being both the Sheriff "helping" York with the investigation (and thus receiving a lot of screen time throughout the game) and the New Raincoat Killer; as does Thomas, due to his relationship with George, his own status as a minor villain, etc.
** Zach, York's NotSoImaginaryFriend. The first reveal of his origins, given midway through the game, is a big enough spoiler on its own, but there are spoilers ''behind'' those spoilers, escalating all the way up until the end of the game, when Zach's true nature as the [[DecoyProtagonist real protagonist]] is revealed, and [[TomatoInTheMirror York is shown to be the imaginary one.]]
* About 2/3 of the way through ''VideoGame/FinalFantasyV'', the party meets Krile. She is a friendly young girl. This is the most detail you can describe her with if you don't want to reveal that she is Galuf's granddaughter, a princess (because he is really a king), or that she [[TakeUpMySword takes his place]] upon his death.
* ''VideoGame/FinalFantasyVI'' has Terra Branford. These days the fact that she is half-Esper has entered ItWasHisSled territory, even being a central part of her combat methods in ''VideoGame/DissidiaFinalFantasy'', but at the time it was a pretty big surprise only revealed several hours into the game (although it was {{foreshadow|ing}}ed before then).
* ''VideoGame/FinalFantasyIVTheAfterYears'' has the Creator. Not only is it impossible to describe without spoilers, its name and even its very ''existence'' are major spoilers.
* ''VideoGame/TheBindingOfIsaac''
** The game takes the cake with '''five''' different examples, primarily due to the abundance of [[BrutalBonusLevel bonus levels]]. The first two, Mom's Heart and It Lives, are mostly out of this territory since their section of the dungeon is almost immediately unlocked. Satan, secret boss of Sheol, is considerably more of a spoiler, but probably more well-known since the Halloween update has been out for a while. The biggest is Isaac, the boss of the Cathedral in the DLC Wrath of the Lamb.
** The Chest. It's the ''*deep breath*'' mega ultimate super-secret final level. It can only be reached by defeating, well, yourself in The Cathedral while holding The Polaroid (it's a Polaroid photograph depicting three people, most likely Isaac, his mother and his father). Getting through ''that'' and beating its boss (???/Blue Baby) will give you what the developers of the game themselves call the closest thing the game has to a canon ending.
** The remake ''Rebirth'' adds a few more. The first is the Dark Room, a floor of equal standing to the Chest. You reach it by beating Satan enough times and unlocking a dark version of the Polaroid called the Negative. Its boss is a demon called The Lamb, and beating it unlocks an ending where Isaac goes missing.
** Beating either ??? or The Lamb allows you to fight the statues in the Angels Rooms, who formerly just gave you an item in the Wrath of the Lamb DLC. Beating two angel statues allows you to fight the definitive true final boss of the game: Mega Satan.
** There's also the infamous SecretCharacter known as The Lost. He's a OneHitPointWonder who has a ''[[GuideDangit very complicated]]'' unlock process.
* In ''VideoGame/DiabloIII'', the true identity of the Stranger that fell from the sky is not revealed until the very end of Act I, where it turns out to be a newly-human Tyrael who has sacrificed his angelic status to aid humanity directly against the last two Lords of Hell. He plays a major role in the rest of the game, serving as the de facto leader of your small party and even taking up his sword, El'druin, to battle alongside you at certain points in the final two acts.
* Tiki Tong in ''VideoGame/DonkeyKongCountryReturns''. If you lose a life in any level, you get a silhouette of the instrument tiki's face as the screen transitions to the lose a life screen. In the volcano, which is the last world, Tiki Tong's face is replaced with a question mark before you meet him.
* In ''VideoGame/JadeEmpire'', the three main antagonists - Death's Hand, Emperor Sun Hai and Master Sun Li - fall under this trope. Said characters play with the BigBad and TheManBehindTheMan tropes, causing a lot of spoiler tags on their entries in the character sheet.
* ''Videogame/FireEmblem:''
** ''VideoGame/FireEmblemAwakening:''
*** "Marth" not actually being the [[VideoGame/FireEmblemShadowDragonAndTheBladeOfLight original Marth]] is one of the few things that ''can'' be left unspoilered... but only if you construct the sentence without gendered pronouns, because this Marth is in fact Lucina, the main character's ''[[KidFromTheFuture daughter]]'' [[KidFromTheFuture from the future]].
*** The Hierophant is introduced as simply someone high up in the Plegian order, but then they take off their hood and it's revealed they have the same appearance as the player-created Avatar...because they're actually the Avatar from the BadFuture, possessed by Grima.
** ''VideoGame/FireEmblemFates:''
*** King Garon is a major one. The fact that he's the BigBad of ''Birthright'' and ''Conquest'' [[ObviouslyEvil isn't much of a spoiler]], but what ''is'' is that he ''isn't really Garon'': the real Garon is DeadAllAlong, the Garon we see is a monster posessing his corpse.
*** Takumi is the other big one. Originally introduced as the younger brother of the Hoshido siblings who [[DislikesTheNewGuy doesn't trust the main character very much]], it's hard to talk about him without mentioning that his envy and MiddleChildSyndrome [[MoreThanMindControl results in him]] being posessed by the GreaterScopeVillain, and that he's the FinalBoss of the ''Conquest'' route.
*** Flora, one of Corrin's maids, also counts, as her becoming an AntiVillain on the ''Birthright'' route, and being DrivenToSuicide after being defeated, comes as a major shock.
*** Gunter is set up as the CrutchCharacter, but seemingly suffers an unavoidable PlotlineDeath very early in the game. On ''Conquest'', this is revealed to be a DisneyDeath, but his true role doesn't become clear until ''Revelation''.
* ''Franchise/ProfessorLayton''
** Clive, from ''VideoGame/ProfessorLaytonAndTheUnwoundFuture''. AKA, Future Luke. It's difficult to talk about Clive's real personality without spoiling the time travel disaster from 10 years ago, or the fact that one of your traveling companions is the BigBad.
** Dimitri Allen AKA, Dr. Alain Stahngun and Future Layton also counts, especially given his ties to the backstory.
** From ''VideoGame/ProfessorLaytonAndTheMiracleMask'' we have Randall Ascot, AKA The Masked Gentleman. Referring to him by name reveals that Randall actually ''didn't'' die in the backstory. Though, the amount of buildup they give the character in his backstory, it's almost impossible to not see that twist coming.
** From ''VideoGame/ProfessorLaytonAndTheAzranLegacy'', there's Leon Bronev, who is not only the BigBad, but Layton and Descole's father, Emmy's HonoraryUncle and boss, and a somewhat more sympathetic character than he initially seems.
* Pat Sprigs in the first ''VideoGame/MegaManStarForce'' is at first just a student in Geo's class. Then it's revealed he was abandoned by his parents in Dream Island, has a SplitPersonality and also hosts an FM-ian. And that's just the tip of the iceberg...
* ''VideoGame/{{MOTHER 3}}''
** The Masked Man had many of his tropes spoilered because he was actually Lucas' brother Claus. This warranted a hard split between the Masked Man's tropes and Claus' tropes.
** Porky, since before he appears there's little indication that the game's plot is actually directly connected to [[VideoGame/EarthBound the previous game]].
** [[VideoGame/{{Mother 1}} The first game]] had [[LukeIAmYourFather George, Maria]] and [[BigBad Giegue]], and their connections to the main character.
* ''VideoGame/ShinMegamiTenseiII'':
** Zayin is advertised alongside Aleph, Beth, Gimmel, and Daleth as a major character. The twist is that, of those characters excluding [[TheHero Aleph]], Zayin is the only one who actually stays as a major force throughout the game. He ultimately becomes a BigBad in his own right and is the direct leader of the Law faction in God's name. Furthermore, he is actually Satan, and he redeems himself on the Law route.
** The Center Elders are actually the Archangels. Gabriel is a decent person, but Michael, Raphael, and Uriel are far worse than they were in [[VideoGame/ShinMegamiTenseiI the last game]] and are the main antagonists for a good portion of the game, at least until Aleph and Hiroko kill them.
** YHVH, the GreaterScopeVillain for Law, is the FinalBoss and final antagonist of the game. This one, [[NoExportForYou against all odds]], fell into ItWasHisSled category, to the point where it's the first thing people generally find out about the game.
* ''VideoGame/ShinMegamiTenseiIIINocturne'':
** Hikawa, Isamu, and Chiaki go OneWingedAngel and are, in their separate fights, all the penultimate bosses of the game. This is especially true for the latter two, who go crazy as a result of their experiences.
** Futomimi and Sakahagi are actually the incarnations of the positive emotions of a child serial killer and the negative emotions of a failed businessman, respectively.
** Hijiri is also a Manikin, though a special one who, like Futomimi and Sakahagi, comes from one human. Furthermore, he may or may not be [[VideoGame/ShinMegamiTenseiII Aleph]], but at the very least, he was punished by God for committing the ultimate sin.
* ''VideoGame/ShinMegamiTenseiStrangeJourney'':
** The Three Wise Men are the leaders of the Law faction. There's not much else to them, but they end up being defined by this.
** Mastema, rather than being a polite, caring angel, is actually a twisted, hate filled, prejudiced monster. This is only revealed on the Chaos path, but his actions go as far as to disgust Lucifer.
** Captain Jack and his subordinates seem to be affable folks looking to gather forma for a business client, offering their services if you obtain some rare forma for them. You later find out that [[HumansAreTheRealMonsters they're some of the biggest monsters in the game]], tearing apart demons and putting them back together in a crude attempt at demon fusion as experiments on behalf of said client and attempting to fuse your comrade Jimenez -- also a human -- with his pet demon.
** Mem Aleph by virtue of Maia Ouroboros from three sectors before [[DiscOneFinalBoss being presented like the final boss of the game]].
* ''VideoGame/ShinMegamiTenseiIV'':
** The Black Samurai is Lilith. She, along with Tayama, is a major antagonist up until the White show up.
** Tayama does not have Tokyo's best interests at heart and harvests brains from children and dissenters.
** The White's existence is a spoiler, but their goals of omnicide and their despair are even worse.
** Merkabah and Lucifer, the alignment leaders. Neither are brought up until the end of the game, yet they become the main antagonists.
** Masakado is your greatest ally in the Neutral path and the presumed leader of the National Defense Divinities. He is also the last of the DLC bosses. He doesn't even appear at all or gets mentioned to on any non-Neutral path unless you buy and use his DLC.
** Mastema isn't really DemotedToExtra, but rather, a figure that plays upon both the idea that he made a HeelFaceTurn and the idea that he hasn't changed a bit. He also sealed away the Archangels.
* ''VideoGame/ShinMegamiTenseiIVApocalypse'':
** Shesha grows sentient throughout the game and eventually impersonates Flynn from Tsukiji Konganji until after Merkabah and Lucifer's deaths, where he delivers the game's biggest WhamEpisode.
** Merkabah and Lucifer are actually Satan. Satan has been perpetuating the ForeverWar through his two halves.
** YHVH is, once again, the FinalBoss. He was the one responsible for Satan's actions.
** Jonathan and Walter return to help in the final battle with YHVH on the Peace Route.
** [[VideoGame/ShinMegamiTenseiI The Hero]], [[VideoGame/ShinMegamiTenseiII Aleph]], and [[VideoGame/ShinMegamiTenseiIIINocturne the Demi-fiend]] return in the final DLC to fight against Stephen, who in turn turns out to be more powerful than YHVH.
** The Great Will aka the Axiom, the ambiguous divine entity that's been alluded to many times throughout the series, is finally revealed in this game to be a ''BigGood'' to humanity, having created the messiahs Nanashi/Akira and Flynn/previous-summoner-of-Masakado to defeat YHVH, who is a rogue avatar of it.
* ''VideoGame/{{Persona 4}}''
** Namatame and Izanami. Both were introduced in the very beginning of the game, but their characterization was so minor that the player is likely to have forgotten them completely- particularly Izanami, who's a nameless gas attendant who only shows up near the beginning and on rainy days. The revelation of what Namatame did marks the beginning of the point where the game becomes a conga line of plot twists, and Izanami turns out to be TheManBehindTheMan [[OverlyLongGag Behind The Man Behind The Man Behind The Man]] that was responsible for just about ''everything'' that had happened up until that point.
** Tohru Adachi is the murderer. The amount of tropes that comes with this revelation is just staggering, to the point that the post-reveal tropes about him were moved to a different page.
* ''VideoGame/{{Persona 3}}'':
** Ikutsuki is introduced as the BigGood, but in reality, he tricked you into killing the Shadows to cause the Fall.
** Ryoji initially seems like just another transfer student, but in reality, he's Death. Talking about him also spoils that the game doesn't end after you kill the Hanged Man, the last of the Full Moon Shadows.
** Aigis for [[SealedEvilInACan sealing Death inside the protagonist 10 years ago]].
** The protagonist's homeroom teacher Ms Toriumi, since it's pretty much impossible to talk about her without mentioning she's actually the Hermit Social Link, something that's hidden until near the end of the game, after you complete the link.
* ''VideoGame/{{Persona 5}}''
** Kunikazu Okumura and his daughter Haru. It's relatively difficult to talk about them without revealing that after Kunikazu's heart is stolen, the Conspiracy kills him, to [[HeKnowsTooMuch keep him quiet]] and frame the Phantom Thieves for his murder, which also profoundly impacts Haru.
** Lavenza, who's the true avatar of power in this game, and a fusion of Justine and Caroline. Discussing her spoils several plot twists, such as ''why'' she was split in two.
** Goro Akechi. He's initially introduced as a detective investigating the Phantom Thieves, until he joins the party (which, unlike with the other Thieves, was not officially publicized). He turns out to be [[TheMole the traitor in the party]] that was mentioned at the start of the game, the "Black Mask" Persona user who killed Futaba's mother and Haru's father, a Wild Card user like the protagonist, and the [[BastardBastard illegitimate son]] of [[BigBad Masayoshi Shidou]].
** Yaldabaoth, the Demiurge. Like Izanami, his true identity and role are only properly revealed at the end of the game, and among them is the fact that he impersonated [[BigGood Igor]] and has been manipulating you for the entire game.
* In ''VideoGame/EVOSearchForEden'', the FinalBoss and Big Bad, Bolbox, as well as the {{Greater Scope Villain}}s and {{Well Intentioned Extremist}}s, the Whispers/Martians, are extremely spoilerifc. Bolbox isn't even hinted at until the end and the Whispers only appear in secret areas before the ending.
* The FinalBoss of ''VideoGame/{{killer7}}'', Greg Nightmare, deals with this due to being killed before his debut and being involved with a massive conspiracy about the power of America.
* In ''VideoGame/HyperdimensionNeptuniaVictory'', Rei fits this trope like a glove. Prior to release, she's only billed as one of the Seven Sages, aka the villains of the game. What Compile Heart ''doesn't reveal'' is that she's the one who sends Neptune into the past, pulls off an epic SlasherSmile, and surprising a lot of gamers, is the TrueFinalBoss instead of Magiquone/Arfoire.
** Its sequel ''VideoGame/HyperdimensionNeptuniaVictoryII'', we have Kurome Ankokuboshi. Unlike Rei, she doesn't have any mention in some preview articles. However, one of the premises suggesting one of the main characters will fall into the dark side. At a first glance, many player believes Neptune is the one who fell into dark side, but it reveals that Uzume (particularly the original one) ''is'' the one who fell, as well as the one who responsible for the destruction of her Zerodimension's counterpart dimension and Gold Third incident.
* ''Franchise/MetalGear''
** Big Boss in ''VideoGame/MetalGearSolid4GunsOfThePatriots'' appears for the last hour (give or take) of the game[[note]]A game that, on a player's first playthrough, would take at least ''nine hours'' to complete from start to finish[[/note]]. His whole presence is a spoiler in on itself, along with Major Zero, since Big Boss was supposed to have been dead for almost twenty years and Zero would be clocking in ninety years old at the very least. Both of them, their presence, and their allegiances are also crucial to understanding about half the plot of the series, so anything they say can become a spoiler.
** Senator Steven Armstrong in ''VideoGame/MetalGearRisingRevengeance''. While seemingly a behind-the-scenes villain, one could not have guessed that the guy turns out to be a nanomachine-enhanced freak of nature capable of tossing Raiden around like a ragdoll. However, he's quickly becoming a FountainOfMemes for this very reason, as well as being an absolutely hilariously hammy villain.
** ''VideoGame/MetalGearSolidPeaceWalker'' has Paz Ortega. Fans can't talk about her without discussing her reveal as TheMole near the end of ''Peace Walker'', her [[DisneyDeath apparent death]] at the end of said game and, more recently, confirming said DisneyDeath in ''[[VideoGame/MetalGearSolidVThePhantomPain Ground Zeroes]]'' only to kill her off ''again''.
** ''VideoGame/MetalGearSolidVThePhantomPain'' has Ishmael, the Medic from ''[[VideoGame/MetalGearSolidVThePhantomPain Ground Zeroes]]'', and Venom Snake himself. Giving details about any of them will spoil the major TwistEnding the game has, as all three are directly connected to it.
* ''Franchise/TheLegendOfZelda'':
** ''VideoGame/TheLegendOfZeldaOcarinaOfTime'' has Sheik, the enigmatic {{Ninja}} who helps Link enter the various temples in the second half of the game and who is revealed right before TheVeryDefinitelyFinalDungeon to actually be Princess Zelda in disguise.
** ''VideoGame/TheLegendOfZeldaMajorasMask'' has the Mask itself. For most of the game, you're led to believe that all the problems was the Skull Kid's doing, then you find out that [[DemonicPossession The Mask itself was controlling the Skull Kid]].
** Demon King Demise from ''VideoGame/TheLegendOfZeldaSkywardSword'', due to being [[BigBad Ghirahim]]'s master, and [[GreaterScopeVillain the very reason for Ganondorf's existence]], who himself is a Walking Spoiler [[HijackedByGanon depending on the game]].
** Hilda from ''VideoGame/TheLegendOfZeldaALinkBetweenWorlds'' due to her TragicVillain BigBad status, where the previous BigBad was made out to be only Yuga. She's the one who wants to revive Ganon in this game. Ravio also counts since he's actually the Lorulean counterpart to Link himself, which isn't revealed until after defeating the FinalBoss.
** Dorian from ''VideoGame/TheLegendOfZeldaBreathOfTheWild'', due to him turning out to have been a defector from the Yiga Clan whose wife was killed by them in retaliation and who was forced to spy on Kakariko Village and eventually steal the Sheikah Heirloom to keep them from killing his daughters as well. Before the quest to retrieve the Heirloom, you are lead to believe he is just a minor guard [=NPC=].
* Everything about Oersted from ''VideoGame/LiveALive'', other than maybe the first half hour of his chapter, is a pretty big spoiler.
* The Trinity in ''VideoGame/{{Skullgirls}}''. As of the non canon storylines they haven't made an actual appearance in the game, other than an EarlyBirdCameo in the GainaxEnding[=/=]{{Cliffhanger}} ending upon beating Double's Storyline, which suggests that none of the storylines are canon, and that the True Ending turns out to be a SequelHook.
* Franchise/SonicTheHedgehog
** ''VideoGame/SonicHeroes''
*** Mentioning that Shadow the Hedgehog is in this game would clue you in to the fact that he didn't really die in [[VideoGame/SonicAdventure2 the previous game]]. Then again, the fact that [[VideoGame/ShadowTheHedgehog he had his own game after that]], and has appeared in most ''Franchise/{{Sonic|TheHedgehog}}'' games in some fashion since then, the fact that anyone ever thought he was actually dead is taken for granted.
*** Metal Sonic being the BigBad in that game, [[TrailersAlwaysSpoil although spoiled by trailers and even in-game cinematics and other materials]], was a ''very big'' revelation at the time of ''Heroes''' release (and the page here still treats it as such by keeping the entries pertaining to Metal Sonic and his actions during the game, both directly and indirectly, spoiler tagged), [[ItWasHisSled although it's not so much heavily under wraps these days]].
** In [[VideoGame/SonicStorybookSeries Sonic and the Black Knight]], Merlina's really the BigBad throughout the entire game, despite her benevolent actions at first which hides her ulterior motives.
** ''VideoGame/SonicMania'' has Infinite's involvement. It is implied that the entire plot of the game is chasing after power that is connected to Infinite and the events of the end of the game sets the entire stage of ''VideoGame/SonicForces'' in motion.
* All the player characters other than Max, the main character, in ''VideoGame/{{Sanitarium}}'' are hard to talk about because they're actually forms/alternate personalities that [[TheNthDoctor Max shapeshifts into]]. By itself, that might not matter, but the shapeshifting doesn't occur until about 1/3 of the way into the game and is meant to be a [[ShockingSwerve VERY unexpected plot development]]; it's not something that the player is intended to know ahead of time.
* ''VideoGame/MegaManX''
** Lumine in ''8'', who's kidnapped at the very beginning of the game and isn't seen again until the end, when he (allegedly) [[KilledOffForReal kills Sigma off for real]] and reveals himself as the true mastermind of the game's events.
** Sigma ''would'' count in some ''MMX'' games (just like Dr. Wily would technically count for the [[VideoGame/MegaManClassic classic series]]), if him being TheManBehindTheMan wasn't so common that someone else being the BigBad of the game [[MetaTwist is a bigger twist.]]
* ''VideoGame/MegaManXCommandMission'' has Colonel Redips, who sends Maverick Hunters X and Zero on a mission to quell the rebellion army. After you defeat Epsilon however, Redips quickly stabs them in the back after they return the supra-force metal to him, revealing himself as TheManBehindTheMan to Epsilon and the real mastermind behind the game's events. Spider even more so, because he was Colonel Redips the ''whole'' time.
* Killabilly from ''VideoGame/LollipopChainsaw'', who appears [[NiceJobBreakingItHero only after Juliet has killed all five Dark Purveyors.]]
* Angel in ''VideoGame/{{Borderlands 2}}''. It is very difficult to talk about her in any respect without revealing that she is working for Handsome Jack, is a Siren, and is also Handsome Jack's daughter. Technically referring to her as Angel rather than The Guardian Angel is itself a spoiler.
* ''Franchise/SuperMarioBros''
** Dimentio from ''VideoGame/SuperPaperMario'' is near impossible to talk about without revealing SOMETHING about his motives.
** The very fact that the final boss of ''VideoGame/MarioAndLuigiPartnersInTime'' is ''not'' [[BigBad Princess Shroob]], but her older sister, and that the Cobalt Star Mario and Luigi spent the whole game assembling is actually [[SealedEvilInASixPack her can]], is a massive twist, making the Elder Princess Shroob a definite example.
** The Zeekeeper in ''VideoGame/MarioAndLuigiDreamTeam''. He's only ever encountered about three quarters of the way through the game, is the mystical deity of the island and completely subverts most expectations about how a god like figure is supposed to behave. And plays a major part in the ending.
** ''VideoGame/SuperMarioSunshine'' features the true identity of Shadow Mario, who goes on to become a recurring character in the series.
* Getting a good look at Dracula from ''VideoGame/CastlevaniaLordsOfShadow2'' and ''VideoGame/CastlevaniaLordsOfShadowMirrorOfFate'', or even hearing him speak, gives away the big [[TheReveal twist]] from the end of the first ''VideoGame/CastlevaniaLordsOfShadow''.
* ''VideoGame/TheWalkingDead''. The Mysterious Stranger, when finally revealed, is one huge spoiler since his life is ruined by your group. He questions all of your hard choices. The fact that he's an AntiVillain instead of a BigBad, makes him a walking spoiler.
** Kenny in the Season 2 can count as one too, since his last appearance in Season 1 implied that he died.
** The final battle of Episode 5 Season 2 is a massive spoiler, because it's a fight to the death and it happens between two of your allies; Kenny and Jane.
* ''Franchise/AssassinsCreed''
** Haytham Kenway was successfully kept a secret from audiences for years up until the game's release, yet the first three sequences are played as him and not the main character, his son Connor. The end of [[VideoGame/AssassinsCreedIII the third game]] reveals him to be a templar, and he serves as the BigBad alongside Charles Lee for the rest of the game. Since much of the game's major twists involve him and his relationship with his son, it's pretty hard having a spoiler-free discussion about him.
** ''The FramingDevice of the entire franchise'' is a huge spoiler in and of itself. The existence of [[GeneticMemory the Animus]] was kept secret during the development of [[VideoGame/AssassinsCreedI the first game]], and official media for the sequels continue to say as little about the modern-day plot as humanly possible.
* ''VideoGame/ProjectXZone'': Meden Traore definitely counts and the Portal Stone by extension. He is the leader of the Oros Phlox Organization that keeps hounding you throughout the game, and until he actually appears halfway through the game we're led to believe that Due Flabellum (who turns out to be his wife) is the leader. [[WellIntentionedExtremist His goal is to merge all worlds into one world to make it all a better place then they were individually]], [[RealityWarper completely messing with the boundaries of time, space, life, and death to accomplish this]]. He's also the FinalBoss in the game, opening the intro movie tells you that much once you recognize him. And the kicker is that he and the rest of the Oros Phlox are [[AnthropomorphicPersonification the manifested will]] of the [[ArtifactOfDoom Portal Stone]] itself, making the very artifact thought to be stolen from Mii's mansion the BigBad pulling the strings from behind the scenes ''the entire time.''
* ''VideoGame/{{Ib}}'': Since nearly all of Mary's screen time lends itself to her being a JerkassWoobie CreepyChild [[AxCrazy with a palette knife]] (after being introduced as a CheerfulChild foil [[TheStoic Ib]]), it's very difficult to have a spoiler-free discussion regarding her character.
* Everything in the Sacred Grounds in ''VideoGame/CaveStory'' due to the area's existence being a huge spoiler, which includes both of its bosses, the Heavy Press and Ballos.
* Pretty much every character in ''Videogame/StarStealingPrince''. Astra's not really a DamselInDistress, Snowe's parents are not really dead, Snowe's parents aren't even the rightful rulers of the land, the rightful ruler was even worse than they were and they were pretty awful, and there's also the whole demon thing. Even the girl who appears in Snowe's dreams is not just a dream representation of Astra but a character in her own right, and you'd never guess that unless you went for the BonusDungeon.
** In ''Literature/EphemeralPrince: Fleeting'', the webnovel sequel to the game's bad ending, Hiante gets to join the "Walking Spoiler" pile of characters simply for still being alive. [[DemBones For a given value of "alive" anyway.]]
* ''VideoGame/{{Iji}}'' has an entire ''species'' of this trope, the Komato, whose existence spoils both the true motivations of the Tasen and the second half of the game. Fortunately just mentioning their name them won't spoil anything, as there is a very early InterfaceSpoiler.
* ''VideoGame/WorldOfWarcraft''
** Drakuru in Grizzly Peaks initially seems like just another questgiver, until you discover that he's collaborating with the Lich King against the Drakkari trolls. The latter part is why most people remember and talk about him.
** Archbishop Benedictus initially seems to be nothing more than the leader of Stormwind's clergy, but it turns out that he's actually the Twilight Prophet, and one of Deathwing's highest-ranking followers.
** Y'Shaarj is quite difficult to discuss without spoiling many of the plot twists in Mists of Pandaria. He is the Old God beneath Pandaria who is the source of the Sha, having been killed long ago by the Titans, and the Mantid were created to serve him. Garrosh obtains his heart and plans to use his power against the True Horde's enemies, devastating the Vale of Eternal Blossoms in the process.
* ''VideoGame/SpecOpsTheLine''
** In a rare protagonist example, on the character sheet well over half of the character-specific tropes for Cpt. Martin Walker are spoiler-tagged out. For one thing, knowing that he's actually an [[ObliviouslyEvil unintentional]] VillainProtagonist '''massively''' changes how you view both the game and how you're playing it.
** Col. John Konrad, since for starters, he's, well, [[TheUnfought not really]] [[DeadAllAlong a villain]].
* No less than four of the love interests in ''VisualNovel/HatofulBoyfriend'' have a ton of associated spoilers for the KudzuPlot of the darker routes and backstories. Most of these come up in fandom discussion and/or sequels and manga expansions. In particular:
** Nageki Fujishiro is the ghost of a mourning dove who immolated himself five years prior to the game to prevent the virus he carries being used as a biological superweapon.
** Dr. Shuu (a false identity) works for the Hawk Party to destroy humanity out of affection for Ryouta Kawara's late father.
** Nanaki Kazuaki was "assisted in suicide" and his identity stolen by Nageki's childhood friend Hitori Uzune to seek revenge for Nageki's death.
** Yuuya Sakazaki is a TeenSuperspy working for the Dove Party.
* ''VideoGame/Bioshock1'' has pretty much anything involving Fontaine. The game presents him as being a rival to Ryan, a smuggler, and he died several years ago.
** In addition, the last name of the player character is a major spoiler. though the game does foreshadow it a bit before hand if you find several audio diaries.
* In ''VideoGame/BioShockInfinite'', reading anything online about [[TheHero Booker]], [[RealityWarper Elizabeth]], [[BigBad Father Comstock]], or [[ThoseTwoGuys the Twins]] is a good way to spoil a ''huge'' chunk of TheReveal and the ending, as the spoilers are a core part of each characters' background. Even Comstock's real NAME is a spoiler as to the final revelation.
* ''[[VideoGame/SoulSeries Soul Calibur V]]''
** The names of Alpha Patroklos and Pyrrha Omega give away that those characters will be getting alternate versions somewhere in the story.
** Any discussion of Elysium will give away that the supposed ghost of Sophitia isn't what she appears.
* ''VideoGame/TalesOfDestiny2''
** It's hard to talk about Reala without mentioning she's an ArtificialHuman.
** It's even harder to talk about anything to do with Judas and not mention [[LovableTraitor Leon]] and the fact that he dies betraying the party, though the fact that they're one and the same (barring CharacterDevelopment) isn't really meant to be a huge surprise to the player ([[LateArrivalSpoiler Provided you've played Destiny]]).
* ''VideoGame/TalesOfSymphonia''
** Even if we ignore the fact that Kratos Aurion is [[LukeIAmYourFather the main character's father]] ''and'' that [[ReallySevenHundredYearsOld he was one of the legendary heroes]], you still can't talk about his morality and motivation without spoiling ''something'', be it that he was EvilAllAlong in the first part... or was actually GoodAllAlong at the end.
** Mithos Yggdrasill's name is a spoiler, since we're familiar with two Mithoses--a young boy directly, and an ancient legendary hero from hearsay--(who are actually the same one) and also another, seemingly older, character named Yggdrasill who is the BigBad. Oh, and you're even ''allied'' with boy Mithos for a while.
** Likewise, ''everything'' about Martel. The fact that she is not a goddess is just the beginning.
* ''VideoGame/TalesOfTheAbyss'' has a weirdly literal version with Asch. His powers as the "Light of the Sacred Flame" (or remnants thereof), his reasons for joining Van, his backstory, and even his ''physical appearance'' are all spoiler-tastic. Even seeing his face or hearing his [[Creator/YuriLowenthal incredibly familiar voice]] will probably tip you off to the game's first major plot twist: Luke is Asch's replica. Sync would count for the same reasons, but due to his dramatic voice differentiation from Ion and his signature mask, and due to the fact that his motivations aren't as plot-critical, it's much harder to pick up on.
** Florian is yet another replica of Ion, as well as one who first appears after the Ion replica you know and initially assume to be the original is dead.
* ''VideoGame/TalesOfVesperia'': You can say very, very little about Captain Schwann without revealing that he's Raven. The game is also very careful not to show Schwann's face or have him speak for the same reason.
* You can't talk about Emeraude from ''VideoGame/TalesOfGraces'' without revealing that she's from another planet, goes crazy with power, inhabits a fake body and/or is directly responsible for Lambda's StartOfDarkness. Lambda is even worse for this, since you have to explain that he's a ReallySevenHundredYearsOld OmnicidalManiac {{Energy Being|s}} inhabiting either Richard's brain or Asbel's, depending on the point in the story. As such, some aspects of Richard, like the DemonicPossession, also make him kind of hard to discuss.
* In ''VideoGame/TalesOfXillia'', Maxwell, the Lord of the Spirits is a huge spoiler -- not just for the fact that he's the real [=McCoy=] and not Milla like she claims to be. He also sets the entirety of the game's plot into motion -- he separated humanity into two groups: those who can cast spirit artes and those who can't; placed those two groups into the worlds of Rieze Maxia and Elympios, respectively; created a schism so that the two worlds never meet; and also created Milla, Muzét, and the Four Great Spirits as his pawns to ensure his status quo. When a group of Elympions (Exodus) decides to invade Rieze Maxia for its resources, he directly interferes and plans to exterminate Elympios and its people; until Jude, Milla, and their allies put a stop to his schemes.
** Victor, Elle's father in ''VideoGame/TalesOfXillia2''. He initially is seen in one of the opening cutscenes, setting the game's story into motion by sending Elle away and is then seemingly shot dead by a mob of Clanspia agents, only to mysteriously recover and kill the whole lot of them. He's never seen or even mentioned again until late in the game when you travel to his alternate universe, finally meeting him in person and learning his name (Which is actually more of a title). Shortly after, the truth comes out that he's actually an older version of Ludger who gained the ultimate Corpse Shell by killing off all of the others who possessed the ability, but as a side-effect, has become a Time Factor and has little time left to live. He also happens to harbor one of the Guideposts of Canaan within him, which ultimately makes his death necessary, much to Elle's horror.
* Neyla of ''VideoGame/Sly2BandOfThieves''. She starts out as TheRival, but suddenly pulls a FaceHeelTurn on the main characters and frames her partner. She's soon revealed to be TheDragon to the game's [[DecoyProtagonist Decoy Antagonist]], but then betrays and KILLS him to steal the body of the first game's antagonist, revealing herself to be the second game's BigBad. At the end of the game, she crushes Bentley with her beak, paralyzing his legs and causing Murray to cross the DespairEventHorizon, causing the game's DownerEnding.
** For ''Videogame/SlyCooperThievesInTime'', Penelope's role in the story is a massive spoiler due to her SuddenSequelHeelSyndrome.
* From ''VideoGame/FarCry3BloodDragon'', we have the Battle Armored Dragon Assault Strike System or '''[[FunWithAcronyms B.A.D.A.S.S.]]''' for short, a Blood Dragon that you get to pilot near the end of the game. It also talks and shoots lasers out of its fucking eyes.
* ''VideoGame/RhythmThiefAndTheEmperorsTreasure''
** The only thing not a spoiler about Jean-François is that he takes care of Marie at the convent where she lives. He doesn't take any active role in the story until he assists Leonard at the Eiffel Tower as TheDragon by shooting Phantom R in the foot, taking the protagonist out of commission for a while. Jean-François then shows that he is the "Graf" that Inspector Vergier had been trying to find for several years and that he has the royal blood needed to unearth a superweapon beneath Paris, albeit missing some other necessary ingredients. This new information about him also puts his encounter with Elizabeth in a new light: Elizabeth denied being Marie's mother not because she isn't, but because Elizabeth knew what Jean-François was up to.
** Leonard Bonar himself, as he shows up right at Chapter 1, passing himself off as a resurrected UsefulNotes/NapoleonBonaparte until Phantom R finally defeats him in Chapter 9, when he admits he's a fake. This reveal then sets up subsequent reveals that the ''real'' Napoleon is TheManBehindTheMan and that Raphael's father Isaac may be a more powerful figure in this conspiracy than was previously thought.
* The Phoenix [=MkII=] from ''VideoGame/RefleX'' is a main protagonist example with the majority of its tropes being of spoiler nature. At first, it seems like a simple CoolShip with an AttackReflector and an anonymous pilot, but after it is severely damaged and its pilot killed about 7/8ths into the game, its true nature, unbeknownst to even the pilot, unfolds: the Phoenix is in fact a vessel for the ZODIAC Ophiuchus's core, which has been a major target for the Raiwat army for centuries. The Ophiuchus then causes the destruction of the other 12 ZODIAC units, making the Raiwat retreat out of fear but causing the destruction of a horrifying percentage of Earth and its population in the process. ZODIAC Ophiuchus then makes its HeroicSacrifice and seals itself along with the other 12 ZODIAC cores...only to be revived in the previous ([[BackToFront in release order]]) game ''VideoGame/{{KAMUI}}'' as the "Super KAMUI" fighter that serves as the Area 4 boss.
* It's virtually impossible to talk about [[DudeLooksLikeALady Ren]] and [[TheMentor Lindow]] A.K.A [[FinalBoss Corrosive Hannibal]] from ''VideoGame/GodsEaterBurst'' without completely spoiling the plot.
* The various endgame, bonus and twist bosses in the ''VideoGame/MegaManBattleNetwork'' series. In rough chronological order: The [[TheVirus LifeVirus]], [[PersonOfMassDestruction Bass.EXE]], [[TragicMonster Zero.EXE]], [[BackFromTheDead LifeVirus-R]], Gospel, [[EldritchAbomination Alp]][[PsychoPrototype ha]], [[UltimateLifeForm Serenade.EXE,]] and [[FusionDance BassGS.]]
* You cannot go into a discussion in ''[[VideoGame/SuperRobotWarsOriginalGeneration The Second Super Robot Wars Original Generation]]'' without mentioning that Arteil Steinbeck is really [[VideoGame/SuperRobotWarsAlpha Euzeth Gozzo]] who is the same BigBad from ''a different VideoGame/SuperRobotWars game''. And it's not even an alternate universe version of him, it's ''really him'' thanks to {{Reincarnation}} from the Cross Gate Paradigm System. [[MemeticMutation Sore mo watashi da]] indeed.
* Clare from ''VideoGame/BraveSoul'' is the answer to the game's biggest mystery. She's Rudy's "Moon Goddess," who's been [[GirlOfMyDreams appearing in Rudy's dreams for ten years]]...and she's also Shell, the dragon whose life he saved ten years ago, and his constant companion ever since. The two facts are related.
* ''Franchise/RatchetAndClank'':
** Captain Qwark has a problem with this in the first 3 games. In ''VideoGame/RatchetAndClank2002'', it's hard talking about him without revealing that he's a FakeUltimateHero who backstabs Ratchet and Clank on Umbris. In ''VideoGame/RatchetAndClankGoingCommando'', it's hard talking about him without revealing that he's the BigBad of the game. In ''VideoGame/RatchetAndClankUpYourArsenal'', it's hard talking about him without revealing that he's the one who defeated Dr. Nefarious previously, that he has a DisneyDeath on-board Nefarious' ship in the Zeldrin Starport and that he's FakingTheDead.
** In ''VideoGame/RatchetAndClankSizeMatters'', the little girl who likes to take pictures, Luna, is ultimately revealed to be the TheDragon to Otto Destruct. Not only that, she's actually revealed to be a [[NoBiologicalSex genderless]] warship/puppet built to lure Ratchet into a trap.
** Dr. Nefarious gets this for backstabbing Chairman Drek in ''VideoGame/RatchetAndClank2016''. There's not much else to say about him before the event.
* In ''VideoGame/StarCraftII'', the very fact that Samir Duran appears in the game at all, along with Alexei Stukov. Also the existence of GreaterScopeVillain Amon, since he has basically run the entire plot since Day 1, [[SpannerInTheWorks with the exception of the terrans]].
* ''VideoGame/YsSeven''
** Tia appears as a simple flower girl that Adol [[TheDulcineaEffect just has to help]]. Later you learn that she's really eldress Tialuna of the Moon Tribe, the BigBad, out to destroy the world to return it to its proper balance.
** Cruxie appears as an IllGirl that her brother Mustafa takes care of. After you gain the Fire Dragon Stone, she gets better and ''replaces'' her brother for the remainder of the game. That's right, Mustafa is really the GuestStarPartyMember.
* ''Videogame/DarkSouls'' has all the bearers of the Lord Souls, who are little more than shadows of their former selves compared to their appearance in the prologue. This is mostly pronounced with the Witch of Izalith, who got turned into the Bed of Chaos after a disastrous attempt to re-create the First Fire, and ultimately gave birth to demons all over Lordran. ''[[DownloadableContent Artorias of the Abyss]]'' adds Artorias himself, who is corrupted beyond recognition, and Manus, the BigBad of the content and the former's corrupter.
* ''VideoGame/RuleOfRose'': Despite the game's AllJustADream [[MindScrew Mind Screw-y]] nature, one thing is for certain: avoiding spoilers is near-impossible when discussing [[{{Yandere}} Wendy]], [[DeadAllAlong Joshua]] or [[CryForTheDevil Gregory]] in any kind of depth.
* ''VideoGame/HauntingGround'': Lorenzo, who spends 3/4 of the game as a MysteriousInformant, can't be talked about without giving much away (especially given that his ''first'' cutscene is a MotiveRant about how [[IHaveYouNowMyPretty he now has Fiona all to himself]]). [[CloningBlues Riccardo]] is also pretty spoiler-heavy.
* ''VideoGame/TheWitchsHouse'': Literally'' [[UpToEleven everyone]] ''in the game, due to its CruelTwistEnding and VillainProtagonist status. [[TheDogIsTheMastermind Even the cat leads to immense spoilers.]]
* Iris Zeppelin from ''VideoGame/{{Rosenkreuzstilette}}'', for being an OmnicidalManiac and the true BigBad of both games instead of the innocent girl she first appeared to be.
* For ''Videogame/{{Scratches}}'', the fact that Robin is still alive and in the mansion is the biggest PlotTwist of the game.
* Isabela Keyes becomes this big time in ''VideoGame/DeadRising3''.
* In ''VideoGame/DisneyPrincessEnchantedJourney'', BigBad Zara appears only for the final boss fight.
* ''VideoGame/FTLFasterThanLight'' has the Crystal race, which is designed to be a secret in-universe and out. However, due to the requirements for their sector and ship being so [[ThatOneSidequest infamously]] [[LuckBasedMission dependent on the RNG]], they are squarely a case of ItWasHisSled.
* ''Franchise/SilentHill'' has Alessa Gillespie, whose existence and backstory are major spoilers for the setting of [[VideoGame/SilentHill1 the first game]] and [[TomatoInTheMirror a major twist]] in [[VideoGame/SilentHill3 third game]], as well as being the ultimate cause of the series as a whole.
* ''VideoGame/TheBlackwellSeries'' has Madeline. Very little is known about her, and even ''that'' small bit of information is full of spoilers.
* ''VideoGame/SyphonFilter 2'' has Jason Chance who was working for the Agency all along..
* In the ''Franchise/AceAttorney'' series, each of the games' main antagonists count, as well as many of the murderers in each individual case. Naturally, discussing much about them would reveal that they're responsible, as well as, in some cases, [[BeneathTheMask their true personalities]].
** Probably the biggest example is Bobby Fulbright from ''Dual Destinies'', who is introduced 5-2 as the InspectorLestrade role that Gumshoe and Ema filled. Then the game drops a bombshell by revealing that he's actually Phantom, an emotionless agent who murdered Fulbright prior to the story's events and stole his identity, as well the killer of both Clay Terran and Metis Cykes. This is revealed ''very'' late into the game's events, but is a massive twist, especially since Fulbright is one of the last characters one would suspect as the BigBad given his role and much of the {{Foreshadowing}} towards the revelation is very subtle.
** Matt Engarde from ''Justice for All'' is a very special case as his true personality is denoted by his TwoFaced scars, hidden by PeekABangs until Phoenix Wright gathers enough evidence to reveal his secret. Therefore, anyone foolish enough to Google his name before finishing the game will find the majority of image results to show Engarde with his obviously evil scars and SlasherSmile.
* ''Franchise/FiveNightsAtFreddys'' has many spoiler-heavy characters, as each of the four games have a rather hidden and complex backstory:
** Golden Freddy, Shadow Freddy and Shadow Bonnie, the former from the first game and the latter two from the sequel. Knowing even a little bit about them can ruin the surprise on the rare chance you run into them, and the former slowly comes into importance in the backstory.
** The Purple Man and the Puppet, both debuting in [[Videogame/FiveNightsAtFreddys2 the sequel]], are incredibly important characters in the franchise's backstory. In fact, it's nearly impossible to not spoil the former since he ''only'' shows up in the backstory.
** Springtrap in the third game is a massive one. It's hard to describe it without giving away the fact that there's a human corpse inside the suit. However, thanks to [[http://vignette3.wikia.nocookie.net/fnaf/images/8/88/Springtrap_Rare_3.jpg/revision/latest?cb=20150319192901&path-prefix=pl a few randomly-occurring boot-up screens]], [[ItWasHisSled a good portion of the fanbase knows this already]].
** Both the child protagonist and his BigBrotherBully in ''Videogame/FiveNightsAtFreddys4'' are filled to the brim with spoilers. Without giving too much away, let's just say that they ''[[AmbiguousTimePeriod might]]'' have a very important connection to the franchise's NoodleIncident.
** Fredbear from the same game has more than one [[TheReveal reveal]] to be had, both of which make it harder to explain him without giving them away.
** Circus Baby from ''[[Videogame/FiveNightsAtFreddysSisterLocation Sister Location]]'' is more than players may assume her to be, making discussion of her role difficult. From the same game is Ennard, and talking about it is flat-out impossible without giving away a few major twists revealed on Night Five. And as of the Custom Night update, the true identity of protagonist Eggs Benedict is a massive twist on the franchise's lore.
* The Judge in ''VideoGame/{{Poacher}}''. He's present from the beginning as the game's narrator, but knowing his ''name'', let alone who he really is, is a massive spoiler for the secret ending.
* ''VideoGame/DragonFable'': How do you mention the Mysterious Stranger without revealing that he was the true mastermind behind everything that happened over the entire first chapter of the game? You don't. How do you talk about Wargoth without revealing that the one you fight throughout the second chapter is actually Warlic's demonic half that split from his human half and took form after Warlic [[PhlebotinumOverload overloaded his mana pool]], by creating a light sheild to protect Falconreach from the Mysterious Stranger? You don't. How do you mention Jannia, the ArcVillain of the third chapter, without addressing how she used to be a friend of both Warlic and Xan until she got frozen in everlasting ice during the same duel that turned Xan into the insane pyromancer he is, and that both of them lost their minds due to spending at least several decades trapped in their own mutually-exclusive magical prisons, immortal, but totally awake and aware of the passage of time? [[RuleOfThree You don't]].
* Jergingha in ''VideoGame/TheWonderful101'', the leader of the GEATHJERK, goes un-mentioned until the fifth (of nine) chapter.
* Erim, the Sinistral of Death, in the ''VideoGame/{{Lufia}}'' series. She appears in different mortal guises throughout the series, and her role varies from game to game. One game has her unknowing reincarnation, one game has her observing and manipulating the heroes, and one game has her work ''with'' the heroes to try to stop the Sinistrals for good. Needless to say, it's very difficult to describe Erim's role in the plots without revealing who she is in each game.
* Gamall from ''VideoGame/ThiefDeadlyShadows'' once it's revealed she's been DeadAllAlong and the entity known as The Hag [[DeadPersonImpersonation has been pretending to be her]].
* Iovara from ''VideoGame/PillarsOfEternity''. She reveals that the gods are artificial constructs, and that there is no deeper meaning to the universe, the cycle of death and resurrection, et cetera. It was for revealing all this that Iovara was tortured to death and her soul imprisoned by those who believed the gods were the only way to ensure peace and stability in the world. [[AntiNihilist She takes the world's meaninglessness well]], but the player character has a number of options to deal with the revelation, including deciding TheseAreThingsManWasNotMeantToKnow and telling nobody else.
* ''VideoGame/MegaManV'' has Sunstar, which no mention of whatsoever is brought up until after you've defeated Dr. Wily. He turns out to be the ultimate Stardroid and becomes the FinalBoss of the game.
* ''VideoGame/MegaManUnlimited'' has [[Franchise/MegaManX Zero's]] prototype form, who only shows up in the final Wily Stage and is a PostFinalBoss and HopelessBossFight.
* In ''VideoGame/MegaManRockForce'', Justice Man is revealed to be the one behind the events of the game, having decided to ensure freedom for him and all robots by starting a rebellion against humans and capturing the Rock Force.
* For ''VideoGame/MegaManRevolution'', we have Dr. Remir, who is revealed to be the true BigBad of the game and actually hijacks the plot ''from'' Dr. Wily! In addition, he's also an alien whose race basically created the Evil Energy.
* ''VideoGame/{{Splatoon}}'':
** DJ Octavio is an unusual example in that he's not a Walking Spoiler due to plot reasons (though he has a few surprises). Rather, his characterization and boss fight are so unique and fun that players are very reluctant to give away details to unknowing players. None of this is shown prior to his battle (which is the FinalBoss of the single-player story mode), which adds on to the trope.
** Judd the Cat is a straight example, as his backstory is entirely tied to the spoiler-heavy history of the ''Splatoon'' world, which is not revealed until close to the end of the single-player mode.
* Given [[MindScrew the ways that]] [[AnachronicOrder the plots work]] in ''VideoGame/HotlineMiami'' and [[Videogame/HotlineMiami2WrongNumber its sequel]], most characters and their goals are quite spoiler-heavy:
** Jacket, in a main character variation, is one because of the revelation that he has been in a ConvenientComa for 3/4 of the game, and that most of the MindScrew that happens during it is a result of his coma dream blending together various memories of his.
** The Biker, who is unexpectedly PromotedToPlayable after the player ''thinks'' that the plot has been resolved, and actually goes out of the way to resolve a handful of plotlines at the end. He also returns in the sequel (albeit in a possibly non-canon EasterEgg), which spoils the fact that he survives his fight with Jacket in Neighbors.
** Richter, the one who shoots Jacket's girlfriend, becomes this ''twice''; Not only does he become the cause of Jacket's coma by way of YouHaveOutlivedYourUsefulness, but his role in the second game ([[CuttingOffTheBranches and the fact that he is alive during the 1990s]] as well) shows that he is much more sympathetic of a character than the first game led players to believe.
** The Janitors, who turn out to be the duo who run 50 Blessings, the organization that the above three work for, in order to take out TheMafiya. The fact that they [[CuttingOffTheBranches are also alive in Wrong Number]] counts as well.
** Manny, The Detective, who turns out to be a AttentionWhore RabidCop, instead of an UnscrupulousHero CowboyCop.
** The Solider/Beard, who [[NewJobAsThePlotDemands ran the various establishments that Jacket went to between levels]] in the first game. Not only was he DeadAllAlong before Hotline Miami began, but it turns out his death was the reason that [[RoaringRampageofRevenge Jacket chose to work for 50 Blessings in the first place]].
** The [[TheSquad Ghost]] [[TheDreaded Wolves]]' unnamed commanding officer, whose FreakOut in one of The Soldier's later missions heavily implies that he's the person who originally founded 50 Blessings.
** The Son, whilst not having that many backstory-related spoilers (aside from being [[MeaningfulName the son]] of the first game's FinalBoss), becomes this due to the fact that his death is what most likely is what causes the SuddenDownerEnding.
* ''VideoGame/AkibasTrip'' has Rin, a local pop idol who turns out to be Shizuku's younger sister and like her, a [[OurVampiresAreDifferent Nighteater]] investigating Daishihon Pharmecuticals for their connection to the Synthisters.
** Soga also qualifies, due to being the BigBad as well as Shizuku and Rin's older brother and the one helping Zenya Amo and Koma Sakaguchi.
* The Mother from ''VideoGame/LaMulana'' is impossible to talk about much without going into spoilers about just who she is and her importance to the plot. In fact, the opening cinematic even does its share of spoiling. Some might also argue the existence of Hell Temple as well as the "Treasure That Must Not Be Seen," though those are pretty squarely in ItWasHisSled territory at this point.
* In ''VideoGame/TimeCrisis II'', Robert Baxter is a run-of-the-mill VSSE agent and the player 2 character. In ''Time Crisis 5'', released over fifteen years later, he pulls a big-time FaceHeelTurn and becomes the BigBad, something you don't learn until late into the game. This reveal is quite shocking for series veterans who bother to follow the {{Excuse Plot}}s.
* ''Videogame/{{Disgaea}}'':
** The mere existence of real Overlord Zenon spoils the first half of ''VideoGame/Disgaea2CursedMemories''. The identity of this person (revealed in the final five minutes AFTER the final boss) spoils the entire game.
** Geoffrey is Mao's incredibly efficient butler in ''VideoGame/Disgaea3AbsenceOfJustice''. Anything beyond that description will turn the game on its head.
** Nemo of ''VideoGame/Disgaea4APromiseUnforgotten'' is a mysterious figure working behind the scenes in the Corruptment. To say anymore about him would spoil a huge chunk of the game.
** Xenolith from ''VideoGame/DisgaeaDimension2''. Even his ''character design'' is a pseudo spoiler, since his resemblance to Etna exposes a major plot twist.
** In ''VideoGame/{{Disgaea 5}}'', the only things you can talk about regarding Liezerota without spoiling many critical plot twists are her leoine features and that she's a {{Nice G|uy}}irl. She's that much of a spoiler that Creator/NipponIchi accidentally spoiled one of the game's major twists several months before the release date with a seemingly harmless update to the game's website.
* Given the amount of HiddenDepths its characters have, almost '''all''' major ''VideoGame/{{Undertale}}'' characters have some massive spoilers, which it's barely possible not to mention, but the biggest offenders are:
** Asgore, whose mere appearance is spoileriffic, let alone his personality and actions.
** Both Asriel and the Fallen Child, who, just by existing, mark a turn for either [[GoldenEnding the best]] or [[DownerEnding the worst]].
** Sans, for his role in the No Mercy route and the real reason for his laziness.
** The Amalgamates (and by extension, the True Lab), for their existence being kept a secret (for good reason) and for being heavily involved in one of the characters' backstories and motives.
** Flowey, due to his backstory, true identity, and the nature of his powers.
** W.D. Gaster, who is only mentioned in the spoileriffic True Lab and is involved in a mystery so secret and enigmatic it's [[DummiedOut not even in the game]]. Then again, given his nature, one is extremely unlikely to learn about him without spoiling his existence for themselves unless they either have a field day with their save file or, in the updated version, get lucky with the RandomNumberGod.
** Even the ''player character'' is one. Not Frisk, but ''you'' -- the twist is that the two are entirely separate entities.
** The six human souls are instrumental to defeating the Neutral route's final boss. Problem is, that boss is built around trying to make you feel hopeless, so if you know how to beat him going in, the effect is ruined.
** Let's put it this way: there's [[Characters/UndertaleSpoilerCharacters an entire page with no spoiler tags dedicated to the game's most spoilerrific characters]].
* ''VideoGame/ThreeTheHardWay'' has Anderson, a travelling monk who joined the party seeking for new challenges. That latter claim is a lie, but saying anything about him beyond those facts is going to spoil many important plot points.
* ''VideoGame/ValkyriaChronicles''
** For ''VideoGame/ValkyriaChronicles2'', there's Dirk, one of the members of House Gassenarl (the villains of the game) and also the [[SuperPrototype first Artificial Valkyrur]]. After the attack of Lanseal, he's revealed to actually be Leon Hardins, Avan's brother, who was said to have been killed during a secret mission.
** There's also Baldren, another member of House Gassenarl, who is seen as TheDragon to his father Gilbert and serves as one of the bosses in the game alongside Dirk and Audrey. Then in September, after his father decides to give Gallia to TheFederation and stop the Darscen purges, Baldren snaps, [[TheStarscream kills his father]], takes over as leader of the Gallia Revolutionary Army, and during the game's climax, becomes the [[OneWingedAngel perfect Artificial Valkyria]] and the FinalBoss.
** Headmaster Laurence Kluivert is also this, when it turns out that he was part of the Asgardian Council, helped with Project Valhalla, which involved the research and creation of Artificial Valkyria, and is thus partially responsible for the loss of Leon Hardins' sanity/humanity and also the death of Juliana Everhart.
** In the first game, there's a second character named Isara Gunther seen during the post-credits scene. She's Welkin and Alicia's daughter, spoiling that they get married and [[BabiesEverAfter have a child together]] after the game's end.
* ''VideoGame/ShovelKnight'':
** The Enchantress, who's actually an evil spirit possessing the body of Shovel Knight's long lost friend, Shield Knight.
** Directly tying into the above is Black Knight, whose true motive behind his loyalty to The Enchantress is protecting Shield Knight.
* ''VideoGame/NuclearThrone'' features the titular throne itself, which is the MacGuffin the mutants are searching for. The twist is that the Throne is ''not'' controlled by the skeleton sitting on it, but is in fact a sentient object which serves as the game's FinalBoss. The [[OneWingedAngel Throne II]] fight brings in even more spoilers, as it reveals that the Throne is some sort of EldritchAbomination and may be related to the purple portals that you've been using for the entire game.
* ''[[Webcomic/TeamFortress2 Team Fortress Comics]]'' (supplementary comics for ''VideoGame/TeamFortress2''):
** Bill-Bel and Lar-Nah not only dig into the backstory of one of the nine mercenaries/classes, but their actions kickstart the TraumaCongaLine Miss Pauling's team goes through at the end of ''Blood in the Water'' and all throughout ''Old Wounds''.
** The fact that the mercenaries/classes from ''VideoGame/TeamFortressClassic'' play a big role in the story is already a huge twist, but [[TheStarscream their role]] in ''Old Wounds'' is what really drives the point home.
** The Medic's supposed FaceHeelTurn was also a huge twist before ''Old Wounds'' came out, but said comic reveals that he still cares about his team.
* For ''VideoGame/FairyFencerF'', there's Sherman, a handsome nice guy that believes in justice, wishes to bring peace to the world, and joins Fang and his group at one point. However, he later attacks Tiara shortly before the [[TimeTravel singularity]] happens and in the second timeline, he shows an evil side, kills the president of the Dorfa Corporation, [[KlingonPromotion taking his place]], plans on sacrificing Tiara in order to awaken the [[GodOfEvil Vile God]] so that he can create a new world of peace, is revealed to be the one that killed Tiara in the first timeline, and finally [[OneWingedAngel merges with the Vile God]] and becomes the FinalBoss.
* For ''VideoGame/ToadetteStrikes'', we have not a character, but a ''whole world'' as this. The world in question happens to be Subcon from ''VideoGame/SuperMarioBros2'', except having gone to hell and falling apart due to the dream virus that [[BigBad Kammy Koopa]] has been using to put the Toads in eternal sleep.
** There's also Reckloo, the pair of eyes seen in shadows at various points in the game. He turns out to be the GreaterScopeVillain and TrueFinalBoss ([[AmbiguousSituation and possibly Mario 2's main villain]]).
* In ''VideoGame/DustAnElysianTail'', we have the protagonist himself, Dust, who due to him being an AmnesiacHero on a QuestForIdentity, has a massive amount of spoilers regarding who he really is and what's in his past.
* At the end of the Soviet campaign in ''VideoGame/CommandAndConquerRedAlert'', Stalin's secretary is revealed to be none other than the BigBad of the ''VideoGame/CommandAndConquerTiberianSeries'', Kane.
* Just about every character aside from the six main animatronics in ''VideoGame/{{POPGOES}}'' has a secret to hide. Special mention goes to Strings, one of the other animatronics, who is actually the playable character.
* Thorn in ''VideoGame/{{Caligula}}'' is hard to talk about without getting into heavy endgame spoilers. They at first appear to be Shougo's friend that he got killed (which is quite a spoiler in and of itself) come BackFromTheDead, but turns out to actually be another character entirely.
* Although ''VideoGame/RaymanOrigins'' isn't very concerned with having a plot, it's still difficult to read about the Magician without spoiling the character's significance to the game, as well as its biggest twist. ''VideoGame/RaymanLegends'' makes it even more difficult since [[LateArrivalSpoiler it assumes you know what his deal is by then]].
* Since the plot revolves around trying to understand and defeat the monsters of ''VideoGame/{{Evolve}}'', which initially appear to be nothing more than another dangerous species on [[DeathWorld Shear]], any discussion that involves more detail than that carries major spoilers. Unusually, the biggest spoilers will occur in discussions instead of playing the game, as the expiration of TRS's contract and 2K subsequent cessation of support means TheReveal never got to happen in-game but was instead revealed by the developers in the last few hours when they had creative control.
* In ''VideoGame/StardewValley'', we have Krobus and the Dwarf. Seeing as they're meant to be {{secret character}}s that even have their own {{secret shop}}s, simply mentioning their names can prove to be spoilers.
* ''VideoGame/MonsterHunter 4'' has the Shagaru Magala, the mature form of the Gore Magala who's been hounding you throughout the entire game, infecting some monsters with the Frenzy Virus while it's at it.
* ''VideoGame/Bayonetta2'' has the BigBad Loptr, who masterminded the events of the game.
* ''VideoGame/BanjoKazooie'' has [[DeusExMachina The Mighty Jinjonator]] deliver the final blow to the final boss.
* Anthony of ''VideoGame/EternalDarkness'' isn't a spoiler in himself, and neither is his death; after all, he lived in the year 814, and the game's present day is 2000. What ''is'' a spoiler is that he technically survives his chapter as an [[ZombifyTheLiving undead abomination]] that must be finally put to rest by the next chronological visit to the cathedral, Paul Luther, as a miniboss. A full ''670'' years later.
* Sirius in ''VideoGame/Bomberman64'' initially appears as a friendly ally to Bomberman. After you collect all 100 Gold Cards, it's revealed that Sirius was the original owner of the Omni Cube and had trapped even more galaxies in there than Altair, as he had a proper knowledge on how to use the cube. Sirius makes up lies to Bomberman that Altair had killed his family; however these are false and he uses them to get Bomberman on his side. After he reveals his true intentions to Bomberman, he callously throws him away and nearly destroys Planet Bomber.
