History WalkingSpoiler / VideoGames

** ''VideoGame/PaperMario64'' has Tubba's Heart. He was separated from Tubba Blubba's body and given sentience to make the main body invincible until you defeat the heart and it reunites with the body.

* The ''Franchise/D4DJ'' franchise, particularly its video game branch ''VideoGame/D4DJGroovyMix'' has Lumina Ichihoshi, who at first appears to be a human VirtualYouTuber with a cosmos theme; during a meeting discussing the formation of the DJ unit [=UniChØrd=], the three people who are present in-person for the meeting notice a stranger door labeled as forbidden, assuming it's where Lumina operates and, out of respect for her (since [=VTubers=] generally keep their real-life identities secret), choose not to pry in. Later, when curiousity gets the better of them during a blackout, they enter Lumina's studio and find it empty, upon which Lumina reveals that she's actually an ArtificialIntelligence, a reveal that completely changes every perception of her.

** Guertena, as well, is very difficult to discuss without revealing the fact that he's behind the creations of every artwork that came to life including Mary and how it (in)directly led to the main conflict of the game.

* ''VideoGame/{{Ib}}'': Since nearly all of Mary's screen time lends itself to her being a JerkassWoobie CreepyChild [[AxeCrazy 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.

* ''VideoGame/{{Omori}}'' has Omori, Mari and Basil, initially presented as (respectively) the protagonist, a nurturing figure who provides the game's save points and a missing friend, but whose connected backstories are all very pertinent to the overall story. And tied to them all is Sunny, whose existence reveals that Omori is a DecoyProtagonist and that everything thus far has occurred in his dreams.

* ''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.

** Originally a BonusBoss that [[GiantSpaceFleaFromNowhere had little rhyme or reason to it]], ''VideoGame/PokemonUltraSunAndUltraMoon'' makes Necrozma into the first non-human BigBad, with its backstory and strange appearance being explained. There's also the manner of its unique Ultra Burst technique; something never alluded to until [[ClimaxBoss the final confrontation with it]], and a major revelation into Necrozma's true nature.

* In ''VideoGame/{{Starsector}}'', nothing can be said about the [[BonusBoss Omega]], whether their ships, weapons, or even where they reside without spoiling a major surprise of space exploration.

** For ''Videogame/SlyCooperThievesInTime'', Penelope's role in the story is a massive spoiler due to her SuddenSequelHeelSyndrome.

** 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/SonicFrontiers''

** Queen Sectonia from ''VideoGame/KirbyTripleDeluxe'' comes along with almost no foreshadowing whatsoever, and is one of the only cases of LightIsNotGood in the series.

** Fecto Forgo in ''VideoGame/KirbyAndTheForgottenLand'' gets absolutely no foreshadowing until the end of the game, being the one manipulating the events of the game by brainwashing [[KingOfBeasts Leongar]] and [[TheHeavy King Dedede]] into doing their bidding and leading the Beast Pack to capture the Waddle Dees and power Lab Discovera. While Leongar isn't as bad given that the cages the Waddle Dees get trapped in have lion heads on them, his backstory and relationship with [[SexyCatPerson Clawroline]] are kept hidden until the post-game. There's also Morpho Knight, returning from ''Star Allies'', and just as spoiler-heavy as ever.

** Marx from ''VideoGame/KirbySuperStar'' and Magolor from ''VideoGame/KirbysReturnToDreamLand'' are both notable for betraying Kirby and his friends by using them as {{Unwitting Pawn}}s.
** Zero and 0, appearing in ''VideoGame/KirbysDreamLand3'' and ''VideoGame/Kirby64TheCrystalShards'' respectively, come off as a major surprise; not only because they're the TrueFinalBoss of the games featuring them, but also because they use gratuitous amounts of FamilyUnfriendlyViolence.

** The true form of Star Dream from ''VideoGame/KirbyPlanetRobobot'' is arguably the largest plot twist in the series' history, as it ties back to [[VideoGame/KirbySuperStar one of the franchise's oldest games]] in a very unexpected way. Additionally, President Haltmann's personal motives are kept tight-lipped until much later in the game, and [[TheWoobie for good reason]].
** ''VideoGame/KirbyStarAllies'' is especially bad about this. Not only is [[BigBad Lord Hyness]] an absolutely [[AxCrazy batshit insane]] high priest of an ApocalypseCult, but the FinalBoss is an unfathomably powerful EldritchAbomination whose role in the overarching MythArc seems to tie [[TomatoInTheMirror Kirby himself]] to the Dark Matter race. Even the postgame isn't safe from this, as the FinalBoss of Guest Star ???? mode is [[ButterflyOfDeathAndRebirth a seemingly innocuous butterfly]] that can transform into the ''Kirby'' equivalent of TheGrimReaper by casting judgment on a popular recurring foe.

* ''VideoGame/ToukenRanbu'' gives us the ''other'' Yamanbagiri, the SecretIdentity of the mysterious hooded figure.

* ''VideoGame/IWasATeenageExocolonist'': The game is about a single group of people SettlingTheFrontier on a new planet and the player gets introduced to everyone within that group relevant to Sol's life quite quickly. A second ship always shows up mid-way through the game with no warning from Sol's perspective and it's possible to discover that the sentient species the planet had a long time ago left still-working elaborate OrganicTechnology behind. Both of those facts come with the existence of a few named characters who are quite difficult to talk about without getting into their affiliation with their second ship or their nature as alien ArtificialIntelligence.

*** It's nearly impossible to talk about Lusamone without spoiling that she's the BigBad of Sun and Moon or her changed role and true personality in Ultra Sun and Ultra Moon.

*** For ''Mega Man X: Nightshade'', Bass is the true identity of the BigBad.

* ''VideoGame/IWasATeenageExocolonist'': The game is about a single group of people SettlingTheFrontier on a new planet and the player gets introduced to everyone within that group relevant to Sol's life quite quickly. Eventually, another ship from Earth shows up and it's possible to find out that the sentient species the planet had a long time ago left still-working OrganicTechnology behind. Both of those come with the existence of a few named characters who are quite difficult to talk about without getting into their affiliation with their second ship or their nature as alien ArtificialIntelligence.

** Spamton in particular was the first character to get his own page on this wiki, with almost all of them being spoilers to some degree. The fact that this seemingly random salesman NPC, who is introduced as a rambling homeless guy living in a dumptster, is actually Chapter 2's [[SuperBoss Shadow Crystal holder]] is already enough of a surprise, but he's also very hard to talk about without revealing his role in the [[EarnYourBadEnding secret Weird Route]], or his past and motivations.

* 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.

* Vernon Locke in ''VideoGame/PAYDAY2'', a cyber hacker sent by Murkywater to cripple [=Crime.net=], but instead offers jobs to Bain and his crew instead, [[{{Turncoat}} stealing from his former employer]]. He becomes a walking spoiler when the story gets more serious in 2017, and his role as contractor gets an upgrade to replace Bain after he was kidnapped by [[TheIlluminati the Kataru]]. After the events of "Alaskan Deal" and ''especially'' after Day 1 the Film/ReservoirDogs heist, pretty much all of his actions are spoileriffic to some degree. [[https://tvtropes.org/pmwiki/pmwiki.php/Characters/PAYDAY2ContactsAndContractors His entry on the contractor character page]] used to be mostly spoiler-free before 2017, but now it's pretty much all redacted in spoiler tags due to how deeply woven he is in later events.

* Fake Peppino, the fourth boss of ''VideoGame/PizzaTower'', intentionally has zero foreshadowing/buildup to make his appearence more of a shocker. The FinalBoss, Pizzahead, also falls under this as he [[TheDogWasTheMastermind is revealed to be the one pulling the strings as Pizzaface]] and isn't properly seen in the flesh until after defeating Pizzaface's first phase.

* ''Franchise/{{Pokemon}}''
