History WalkingSpoiler / FanWorks

[[AC:CrossOver]]

* ''Fanfic/{{Origins}}'' (''VideoGame/{{Borderlands}}'' & ''VideoGame/{{Halo}}'' & ''Franchise/MassEffect'' & ''Franchise/StarWars'' MassiveMultiplayerCrossover): The Flood from ''Halo'' is the BigBad. The fact that ''Halo'' is involved at all is also generally spoiler-tagged in entries related to the work. Depending on context, the same can be said of ''Borderlands''.

** Many of the comic's fans refuse to spoil the minor story arc [[WesternAnimation/LooneyTunes Porky Pig]] stars in, which is sometimes dubbed "The Porkening". The arc itself isn't very spoilerrific in regards to the main story, but the [[TearJerker shockingly depressing]] events which occur are considered too great to be spoiled to first-time readers.

[[AC: ''WesternAnimation/TurningRed'']]

* ''Fanfic/SonOfTheSannin'': Rin Nohara's death was pretty much [[PlotTriggeringDeath the event that set in motion everything that happened]] in the ''Manga/{{Naruto}}'' canon. Her appearance in Chapter 40 is just the last of a long string of shocking events in that same chapter, and the circumstances behind her resurrection change completely the implications behind Obito Uchiha's motivations and everything that comes after that.

* ''VideoGame/CMCPlus'': {{Parodied|Trope}} with a fighter in the AprilFools build called "Spoiler", who's a pink [[Franchise/SonicTheHedgehog Knuckles]] with a [[Manga/{{Naruto}} Sharingan eye]]. There's no direct indication what he's spoiling, but he's treated as one to such an extent by both the April Fools build[[note]]Their appearance in the character select is blocked by a "SPOILER WARNING" tag[[/note]] and the base game[[note]]He's featured as a legendary sticker, one that is blocked from view upon obtaining in the gacha[[/note]] that his name is effectively just that. There's also his sticker description, which gives us nothing much else in terms of an explanation.
-->'''Sticker Description:''' cmc v30 coming soon
* ''Webcomic/CoolAndNewWebComic'': Final Agent, a character similar to Doc Scratch introduced in Act 5 who is a "Last Guardian" powered by the "Pink Sun."[[note]]The whole concept is a nod to the long-disproven threory about ''Webcomic/{{Homestuck}}'' having a Pink Sun as a foil to its Green Sun, with their own seperate brand of Guardians, based on a quick image of a pink-tinted sun appearing in "Seer: Descend."[[/note]] The mere existence of Last Guardians is a huge spoiler for the webcomic, as they are not in canon and are explicitely described by Agent as a three-of-a-kind anomaly across the multiverse. The fact that there even ''is'' a character who is a "second Doc Scratch" is a [[WhamEpisode massive twist]] by the time of his reveal, which is lampshaded by the narrator building up his first appearance with plenty of [[StylisticSuck mispelled]] "wait for it"s.
* ''Fanfic/TheConversionBureauTheOtherSideOfTheSpectrum'' has the TheManBehindTheMan, Tirek. The entire [[Fanfic/TheConversionBureau conversion scheme]] turns out to be part of his revenge against [[DisproportionateRetribution the entire human race]] because one single girl named Megan Williams defeated him over one thousand years prior.
* In the third story of the [[Fanfic/DisneysWarACrossoverStory Disney Crossover Series]], it is not revealed that the "Master of Worlds" is actually Alice from ''Alice in Wonderland'', turned insane and evil, until pretty late in the story, and his identity was already a mystery in the previous story, End of Worlds. The origin of his powers was also pretty mysterious, but all makes sense once we know that "he" is actually Alice, who in the context of the series is one of the most powerful {{Reality Warper}}s in existence.
* It's very difficult to talk about WebAnimation/DoubleRainboom without spoiling the [[WesternAnimation/ThePowerpuffGirls crossover.]]
* ''FanFic/{{Eternal}}'' has [[AnthropomorphicPersonification The Sun]], whose presence is a huge spoiler for not only what's been happening to Celestia for the past millennium - and thus what's currently happening between her and Twilight - but the entire reason for it happening in the first place.
* ''Fanfic/ForEarthAndHerColonies'' has two:

* ''Fanfic/GirlsNextTour'' is extremely ''spoilery'' by just looking at the cover art and even a part of Chapter 1 for anyone who hasn't read the entirety of the original [[Manga/GirlsLastTour manga]]. And why is it? Because it clearly takes place AFTER the manga's ending.
* Gouki Namikaze in ''FanFic/AGrowingAffection''. As the GreaterScopeVillain, Naruto's uncle and Minato's brother, the secret mentor of Konan and Nagato, among other attributes, pretty much any important mention of him is going to spoil the last two books.
* ''FanFic/HorseshoesAndHandGrenades'' has many characters with tropes related to them spoiler-tagged. These include: Ryusei Sakuta (who has been brainwashed twice and converted into an android), Kengo Utahoshi (who has become a servant to Ophiuchus as early as Chapter ''2''), Jiro Inseki (the whole reason Ryusei even killed Gentaro in the first place being killed and resurrected), Mei Shirakawa (who was the fortuneteller who pushed Ryusei on the path to kill Gentaro in the first place) and Shotaro Hidari (for becoming a Serpent-bearer and losing his mind.)
* ''FanFic/HuntingTheUnicorn'' has a major spoiler in the form of Alex. He's mentioned in the thirteenth chapter as Blaine's stalker, has a short appearance in the fourteenth, and later appears in the nineteenth chapter where he kidnaps Blaine, Wes, and David. Two more Walking Spoiler characters are Tori Grayson, Nick's divorced father who is secretly a wanted criminal that [[Series/CriminalMinds the Behavioral Analysis Unit]] knows as "Spyke," and Petyr "Littlefinger" Baelish, who broke Alex out of jail because he needs Alex to help him find Blaine's therapist [[Series/GameOfThrones Sansa Stark]].
* ''FanFic/ImperfectMetamorphosis'':
** Rin Satsuki, whose identity, powers (and how she got them) and history are spoilers for the motivations and goals of more than half the cast.
** The Shadow Youkai is a lesser example. Her origins and nature are certainly a spoiler, but her existence is most certainly not, as "Rumia's SuperpoweredEvilSide" has long been a FandomSpecificPlot for ''Franchise/TouhouProject'' fan works.
* It's next to impossible to tell anything about ''[[Fanfic/TheMidnightverse Lost And Found]]'' beyond the first pages until the Rangers encounter whomever Zipper has spotted in the old bomber plane where Gadget used to live. This is because it's her father Geegaw Hackwrench who until then is believed dead. Seeing as ''Lost And Found'' has three acts, Geegaw's presence makes pretty clear whom the other two acts are about.

* ''Fanfic/LulusBizarreRebellion'': An early PointOfDivergence has Lelouch forced to reveal his powers to Suzaku before they even escape Shinjuku, so he is unable to take the role of Zero. However, the big spoiler is that he subsequently convinces Shirley to take up the role instead, as no-one expected for her to have any powers at all, much less be one of the main protagonists. This takes place early into the story, and so it's difficult to discuss Shirley's role without spoiling this twist.

* On the character page of ''Fanfic/AManOfIron'', Sansa's article is almost entirely whited out, due to the game-changing elements of her personal storyline -- namely, her death near the end of the first book and subsequent [[CameBackWrong resurrection as the Night's Queen]] in its epilogue, leading to her becoming a major antagonist in the rest of the series.

* ''Fanfic/MarieDSuesseAndTheMysteryNewPirateAge''
** Monkey D. Madelyn. To make a long story short, she, a World Noble, got her hands on a special Devil Fruit, and used it to fall in love with Trafalgar Law. Unfortunately, as his personality slowly changed because of her influence, she assumed he'd given up on winning the race for ''Manga/OnePiece'', and used her powers to arrange for her brother Luffy to get captured by the Marines so that Law would once again have a shot at winning. Doing so resulted in Luffy getting executed, and his crew dying one by one; overwhelmed by shame, she retreats to the real world, gets married and gives birth to the main character, before events result in her being taken back to the One Piece world 20 years after her departure. If you mention anything about her except her name or status as the "Pirate Queen", you'll give away a plot twist at some point.
** The Disinfector, a.k.a. Trafalgar Law, who also plays a major role in the backstory as Madelyn's lover, and whose identity is kept secret for much of the fic.
* The [[RoboticReveal true nature of the title characters]] in ''Fanfic/{{Marionettes}}'', as the TomatoInTheMirror reveal is a major PlotTwist just before the DiscOneFinalBoss confrontation with [[TheHeavy Gear Shift and Cover Story]].
* ''Blog/{{Moonstuck}}'' has Discord. His very presence spoils not only the ending and the nature of one of the two other villains, but also that the whole thing is set during [[TheDarkTimes his original reign of Equestria]] (and ''not'', as many fans initially assumed, set during [[SealedEvilInACan Luna's imprisonment in the moon]]).
* ''Fanfic/NecessaryToWin'' has Mizuho Miyanaga, who happens to be based on the girl from Chapter 102 and 104 of ''{{Manga/Saki}}''. She was Saki and Teru's adoptive sister and a distant relative, until she died in a tankery match, as a result of Teru saving Saki rather than her, being only to save one. Saki forgetting about Mizuho and Teru's own conflicting feelings about her decision is the cause of Teru's enmity toward her, and Mizuho's death also caused the Miyanagas to break apart. Essentially, mentioning anything about Mizuho, including her name, spoils some part of the Miyanaga sisters' subplot.
* Claire Thompson in ''FanFic/TheNewRetcons'', who's Elly's illegitimate daughter from when she was a teenager. Later, Fiona Brass (who takes a crazed runaway Elly in) and Kortney Patterson, nee Krelbutz (who John had cheated on Elly with, and eventually married).
* Fanfic/ItsNotTheRaptorDNA:
** [[GoodAllAlong Dr. Henry Wu]] is revealed to have done what he did out of UndyingLoyalty to John Hammond, deliberately using Rexy, Sobek and Big One's DNA to make Elise hard to control, alongside using [[LukeIAmYourFather John Hammond's DNA]] in Elise, hoping for Indominus Rex to backfire on Jurassic World and Ingen.
** Tacet the Indomitus Rex's mere existence answers several questions about Elise and Small One.
* In ''Anime/PokemonTheSeries'' fanfic ''Fanfic/{{Obsession}}'', a certain character is referred to only as "Lucrezia's son", covering that he's a certain [[TheDon canon criminal mastermind]].
* In ''Fanfic/{{Origins}}'', a ''Franchise/MassEffect''[=/=]''Franchise/StarWars''[=/=]''VideoGame/{{Borderlands}}''[=/=]''VideoGame/{{Halo}}'' MassiveMultiplayerCrossover, the Flood from ''Halo'' is the BigBad. The fact that ''Halo'' is involved at all is also generally spoiler-tagged in entries related to the work. Depending on context, the same can be said of ''Borderlands''.
* In ''Fanfic/PerfectionIsOverrated'', Meiko is thought to be a friend of Mai's, but it turns out that she's Bachiko's accomplice, having rewritten everyone's memories so that Bachiko could pretend to be an OldFriend of Mai's and she could pretend to be a newer friend, while the two scheme to manipulate various characters' relationships.
* ''Franchise/AceAttorney'' fangame ''VideoGame/PhoenixWrightAceAttorneyConflictOfInterest'' has a similar absence example with Shelley de Killer. It's hard to mention him without spoiling his central PlotTwist... he isn't involved in the game at all. The character two witnesses assumed was de Killer was someone else, and Obadiah Williamson faked de Killer's involvement in the case to lure Phoenix into accepting it.
** The fangame also has Frincisco Mendirez, given that only two things about him are publicly known: his name, and the fact that he's the BigBad. His identity is the fangame's DrivingQuestion. The ''real'' reason Mendirez is a WalkingSpoiler is that ''both these assumptions are lies''. Mendirez is not the game's BigBad, most of the crimes attributed to him were done by the actual BigBad using his name, in an attempt to ruin his reputation with the mafia. Said BigBad? Carlo Luciano, fellow mafia member carrying out an elaborate revenge plot against Mendirez, hoping to fully destroy his reputation to the point where he's begging for death, ''then'' kill him.
* The ''FanFic/PonyPOVSeries'':

* ''FanFic/ThePowersOfHarmony'': Pretty much anything to do with the Guards' true natures, [[BigBad Cetus]], [[TheDragon Eclipse]], [[PoweredByAForsakenChild Horizon]], or [[SealedGoodInACan Harmony]] are spoilers.
* In ''Fanfic/AProtectorsPride'', Hell is a spiritual being and the second arc's BigBad, and the dimension of Hell was actually named after him.
* ''Fanfic/QueensOfMewni'':
** Discussing anything about the "Aurora, the Princess of Another Dimension" chapter not only requires one to know about the GrandFinale of ''WesternAnimation/StarVsTheForcesOfEvil''-in which Star decides to destroy magic, and with the last bit of it she and Marco unconsciously cleaved Earth and Mewni together-but the aftermath of it-a devastating War of Two Worlds that left most of Mewni's population dead (including Moon, Eclipsa, and Meteora) and Star being forced to bring magic ''back''.
** Then there's the big twist that makes all of the canon series and the Aurora chapter even more tragic and hard to discuss otherwise-everything Star did, in particular giving the throne to Eclipsa because she believed herself and Moon to be illegitimate heirs to the throne, was BasedOnAGreatBigLie perpetrated by Eclipsa's ''first'' daughter, Luna the Child, who had tried to erase Eclipsa from history, and whom Star and Moon are descended from.
** Bringing up Comet is hard without noting that RelatedDifferentlyInTheAdaptation is in effect, Comet is actually Moon's aunt, and Comet was technically queen ''regent'' since Moon was queen at a few days old since her biological mother, Sky the Weaver, died from complications from childbirth (and a bit of despair too).
* The ''VisualNovel/KatawaShoujo'' fic ''Fanfic/{{Reconciliation}}'' has an interesting variant in a character whose conspicuous ''[[PosthumousCharacter absence]]'' serves as a Walking Spoiler. It's revealed early on that Hisao has died of a heart attack, setting the plot into motion. Only the most basic description of the setting can avoid mentioning his death, and doing so spoils Hanako's bad ending.

* ''Fanfic/SunsetOfTime'' has the BigBad, Vesper Radiance, wearing a BlackCloak for the first several chapters. The reason is that her eventual identity is not only a big reveal, but completely shifts the tone of the story.
* ''Webcomic/TailsGetsTrolled'':
** Franchise/{{Sonic|TheHedgehog}} is pretty difficult to discuss without mentioning either [[AnyoneCanDie Chapter 4's twist]] or the backstory told through Chapter 19-20.
** [[Franchise/SuperMarioBros Mario and Luigi]] may not seem like this at first since they are portrayed as members of the Troll Slaiyers, but it's soon revealed that they are intentionally PlayingBothSides.
** Many of the comic's fans refuse to spoil the minor story arc [[WesternAnimation/LooneyTunes Porky Pig]] stars in, which is sometimes dubbed "The Porkening". The arc itself isn't very spoilerrific in regards to the main story, but the [[TearJerker shockingly depressing]] events which occur are considered too great to be spoiled to first-time readers.
** Chester Cheetah may initially appear to be the embodiment of TheStoner, but Chapter 20 reveals that he and the other Defenders are ''not at all'' what they seem.

* Widget Hackwrench a.k.a. The Gray Mouse from ''[[Fanfic/TheNowakverse Under the Bridge]]''. In the first two chapters, it's only revealed that she's known as The Gray Mouse, that she's got a submarine, and that she's after the Rescue Rangers. Her name alone is a dead giveaway that she's Gadget's sister. If you know it before you read ''Under the Bridge'' beyond the first chapters, you'll have a pretty accurate idea of things that the fic itself reveals much later. Also, calling her a ByronicHero gives away ''the end''.
* ''Fanfic/WhatTheCatDraggedIn'' has its FinalBoss, Peacemonger. It's practically impossible to talk about him without giving away just who gets [[BrainwashedAndCrazy Akumatized]] into him -- even the name is a pretty big giveaway, thus all references to him on the story's page are entirely whited out.

* ''Fanfic/WashedDownTheDrain'': The summary sells the story as being about Woojin's grief. Like Woojin, the reader spends most of the first chapter believing Joonyeong has perished and Woojin has to move on. The fact that half the chapters are from Joonyeong's perspective would probably indicate that [[ReportsOfMyDeathWereGreatlyExaggerated he's not so dead after all]].

** Bringing up Comet is hard without noting that RelatedDifferentlyInAdaptation is in effect, Comet is actually Moon's aunt, and Comet was technically queen ''regent'' since Moon was queen at a few days old since her biological mother, Sky the Weaver, died from complications from childbirth (and a bit of despair too).

* ''Fanfic/LulusBizarreRebellion'': An early ForWantOfANail situation has Lelouch forced to reveal his powers to Suzaku before they even escape Shinjuku, so he is unable to take the role of Zero. However, the big spoiler is that he subsequently convinces Shirley to take up the role instead, as no-one expected for her to have any powers at all, much less be one of the main protagonists. This takes place early into the story, and so it's difficult to discuss Shirley's role without spoiling this twist.

* ''Fanfic/OneDayAtATimeFanfic'': The Joker's character entry is almost entirely whited out, due to the revelation that there are ''multiple'' Jokers as a result of a thus-far unidentified curse.

* ''Fanfic/LulusBizarreRebellion'': Lelouch is forced to reveal his powers to Suzaku before they even escape Shinjuku, so he is unable to take the role of Zero, but no-one expected him to hand the role to Shirley, or indeed for her to have any powers at all. Since this was revealed in the first fourth of the story, and so it's very hard to mention later events without giving it away.
