History WhamEpisode / FanWorks

* ''Fanfic/TheBridge'':

[[AC:''VideoGame/{{Fallout}}'']]

** "Magical Deja Vu" and "The Aftermath" are more in-universe examples, but still count. An ordinary coronation has several oddities happen for the tangled crew, with Rapunzel reacting to something cold when Elsa walked by her, to Elsa's odd habit of rubbing her gloved hands, to Elsa's sudden snappy demeanor when they request creating trade relations between their kingdoms. However, everything changed for them when Elsa revealed her ice powers. Suddenly, they're made aware of a backstory they could never have guessed about, and what began as an ordinary honeymoon is now as much about the sisters as it is about them.

** "Bonds Tested": Eugene and Rapunzel's secrets are revealed, testing the fledgling bonds they'd formed with the sisters (particularly elsa), and essentially throwing the plot sideways from all the drama it creates.
** "Broken": Kristoff gave Eugene a bad sled when he still hated him, resulting in a broken arm.

* ''Fanfic/IgnitedSpark'':
** Chapter 14 - Storms (Part 1): The Villain Consortium initiates the attack at the USJ. It's confirmed that they were the ones who stole the Trigger gallons from the Humarise cell that was stationed in Japan, and Nine gave a syringe filled with the drug to all the villains at the place (over a hundred or so of them), and by the end of the chapter, he orders them to inject with it, leaving Aizawa and the students surrounded by an army of villains with their Quirks powered up to eleven. And if that wasn't bad enough, is highly implied (and eventually confirmed on the following chapter) that the hooded figure standing alongside Nine, Slice and the Nomu at the plaza is Hood, the High End Nomu that nearly killed Endeavor during the Pro Hero arc.
** Chapter 17 - Aftermath: All for One makes his appearance on the story. Except, he is not on his crippled state, with his head covered in scar-tissue, but his previous one, with white hair and red eyes, which means somehow the mastermind got his hand on Quirk that reversed all the damage from his fight with All Might. He also reveals that while Aoyama failed the entrance exam, he still has a mole inside U.A, and this person was problably at the USJ fighting against the Consortium to keep their disguise. And is confirmed that Hood is actually a merge between Muscular and the unnamed cagefighter.
** Chapter 18 - Realization: All Might confirms that All for One's corpse was destroyed following their fight six years prior, which raises questions over how the villain is not only alive, but very healthy. Meanwhile, Teko reveals himself to be an old guard member of the Yakuza, and discretly decides to gather information about the Consortium with his contacts of the Shie Hassaikai, who also reveal that his son is working alongside Overhaul.

** Chapter 59: Sakura [[spoiler:is once again pregnant... but this time Ronan ''[[ArtisticLicenseBiology and]]'' Naruto are the fathers]]

** The climax of Part I's final arc happens in Chapter 40. For starters [[spoiler: Obito/Tobi tricks Sasuke into believing that he ''killed'' Naruto [[MyGodWHatHaveIDone so the trauma]] [[TraumaticSuperpowerAwakening awakens his Mangekyo Sharingan]]. Then goes the InternalReveal of his true identity to Kakashi and the rest of the adult cast, who believed him long dead, and the icing on the cake, the reveal that he brought [[TheLostLenore Rin Nohara]] [[BackFromTheDead back to life]].]]
** Later on, though, this one is topped by Chapter 122. [[spoiler:Madara Uchiha, [[CameBackStrong fully restored to his prime and stronger than ever]], wreaks havoc all over the Second Division as a display of his new power, fighting and defeating the likes of AdaptationalBadasses Hanabi Hyuga (who has the Tenseigan), Itachi and Sasuke Uchiha together (both with Eternal Mangekyo Sharingan), and Rin Nohara (who, aside from being resurrected with Wood Release, learned to use Sage Mode). It's only through the HeroicSacrifice of Maito Gai, who uses the Gate of Death to fight him, that Madara is put out of comission, albeit only temporarily]].

** Chapter 79: The Akatsuki successfully captures its first jinchuriki. [[spoiler: It’s Killer B, and the Raikage believes Konoha is responsible.]]

* ''Fanfic/EqualAndOppositeAttraction'' has been fluctuating between WAFF slice-of-life and mind-raping Nightmare Fuel. Chapter 25 comes and [[spoiler:Yunno and Chrono, who have been in New York, appear to have been attacked and the Asura can't do a thing to save them.]]

** Arc II, Chapter 21: [[spoiler:Amanda Waller sends [[ComicBook/{{Supergirl}} Kara]] to collect Mari [=McCabe=], and proposes the formation of the [[Franchise/JusticeLeagueOfAmerica Justice League]]]].
** Arc II, Chapter 25: [[spoiler:Tommy gets shot, and thanks to a blood transfusion to save him, [[Franchise/GreenArrow Oliver]] is revealed to be the biological son of Malcolm Merlyn, instead of Robert Queen]].
** Arc II, Chapter 27: [[spoiler:Oliver realizes that Malcolm is the rogue Al Sa-Her, the same time [[Franchise/TheFlash Barry]] discovers the Time Vault and learns that Dr. Wells is the Man in the Yellow Suit. Kara learns that it is her Aunt Astra who is leading the Fort Rozz forces after meeting her Uncle and Astra's husband Non again, and promptly kills Non as a warning to Astra]].

** There was also "Cry for Vengeance" where Dr. Light had the ''entire'' JLA on the ropes, had ''cut off'' Green Arrow's right arm, and almost turned Ralph Dibny in a pile of melted plastic. Cue Sue Dibny, armed with a Franchise/GreenLantern ring and beating the shit out of Light.

* In chapter 5 of ''Fanfic/MarianosBrother''[[spoiler: Camilo is killed protecting Dolores. This completely sets the course for the rest of the fic.]]

* ''Fanfic/LovedAndLost'': The eleventh chapter is mostly a huge JustBetweenYouAndMe moment between [[TheUsurper King Jewelius]] and the imprisoned heroes -- Princess Celestia, Shining Armor, Spike, and the Mane Six (sans Twilight Sparkle) -- whom [[HeroWithBadPublicity he has disgraced]] by tricking everypony to blame them for the Changeling invasion. [[spoiler:Jewelius has [[EvilAllAlong for years before the story began]] secretly hated his aunt Celestia and cousin Cadance [[GreenEyedMonster due to]] their HundredPercentAdorationRating and wanted to overshadow their legacy. He allied with Queen Chrysalis to conquer Equestria on Cadance and Shining Armor's wedding day, but as he became a LoveInterestTraitor for Twilight, he double-crossed the Changelings [[XanatosSpeedChess at the last minute]] by helping Twilight herself to stop them with [[ChekhovsGun the shrinking spell he showed her]], only to immediately afterwards scapegoat all the other heroes for the invasion. During the week the disgraced heroes spent in exile, [[CorruptTheCutie he manipulated Twilight to lose all trust in her friends, brother and mentor]] for [[MadeOutToBeAJerkass their earlier treatment of her]], successfully proposed to her [[DarwinistDesire in hopes of getting powerful descendants]], [[ThePurge murdered all the royal guards]] who [[SickbedSlaying were injured]] during the invasion yet [[UndyingLoyalty remained loyal]] to the princesses, and [[TradingBarsForStripes replaced them with bribed convicts]].]]

* The ''Franchise/TouhouProject''/''LightNovel/TheFamiliarOfZero'' crossover ''[[https://www.fanfiction.net/s/10104947/1/Border-of-the-Void Border of the Void]]'' had a rather suspicious absence of Reimu from the Touhou side. Chapter 32 finally reveals why, as well as why the previous chapter revealed [[spoiler: Flandre]] to be the Blood Devil of the Scarlet Devil Mansion. [[spoiler: Not only is it set 100 years after the Touhou games, but a vampire hunter had managed to kill both Reimu Hakurei and Remilia Scarlet.]]

[[AC:''LightNovel/DemonKingDaimao'']]

[[AC:''LightNovel/HighSchoolDXD'']]

* ''Fanfic/{{Apprentice}}'' in chapter 9 when [[spoiler:the original Dr. Robotnik is resurrected]].

[[AC:''Literature/{{Twilight}}'']]
* ''Fanfic/{{Luminosity}}'' diverges from the original ''Literature/{{Twilight}}'' plotline fairly early on, and diverges from it radically some time later, but there aren't really many wham points, just Bella's decisions building. [[spoiler:Then Edward dies.]]

* ''Fanfic/MegaManReawakened'' has a couple.
** Arc 2, Chapter 5, which introduces the Bonnes in the middle of chapters about Wily and the Powered Up Robot Masters.
** Arc 3, Chapter 8, where Robert has a huge argument with Dr. Light, nearly shattering their familial bond beyond repair.
** Arc 3, Chapter 11, which has a rematch against the Robot Masters wherein Wood Man reveals he's a Reploid, and Robert finally manages to let go of his hate. Tron then convinces Dr. Light to do likewise.
** Arc 4, chapter 4, with Wily being released from jail and apparently reforming, an attack by Quentin Emerald, more details of Project Blues being revealed, Protoman appearing in combat for the first time, and Wily closing the chapter by mentioning Project Gamma.
** The Arc 4 finale has Blues, in his Break Man persona, utterly curbstomping Bass, Wily being accepted onto Project Gamma, the return of the original Robot Masters, an introduction of a new character named Darian Darhk, and the reveal that Blues and Robert are brothers.

* ''All the Laughs We Had in the Past'' serves as one for ''Fanfic/TheOneToMakeItStay''. After witnessing [[AlphaBitch Chloe]] bullying Aurore about being akumatized and calling her on it only to be dismissed, Marinette realizes that she has no interest in changing her ways and confronts her as Ladybug, making clear that she will ''never'' be allowed to be Queen Bee again. Chat then blames Ladybug for Chloe's akumatization into Miracle Queen, and the tension that had been building between them ''explodes'' as he attempts to [[NeverMyFault blame her for everything]] while she [[WhatTheHellHero calls him out in return]]. He then refuses to work with her, splitting off to try and handle Chloe on his own. Miracle Queen and Mayura then exploit this and [[spoiler:successfully steal the Black Cat Miraculous, exposing his identity and getting the ring to Hawkmoth]]. And just in case that wasn't enough of a wham, this ''also'' means that [[spoiler:Master Fu feels it necessary for him to leave Paris, since Adrien knows his identity as the Guardian and has just been compromised]].

* ''Fanfic/MastermindStrategistForHire'' delivers two in a row:
** Chapter 13 concludes with Izuku murdering All Might during the attack at the USJ.
** Chapter 14 has Nedzu reveal that All Might died before finding a successor, meaning One For All died with him.
* ''Fanfic/ViridianTheGreenGuide'': Chapter 4 has Izuku getting into his first official fight as a vigilante to prevent a rape, after which the would-be victim Hina Yu contacts the paper she works at, giving him the name of Viridian in the process.

* ''Fanfic/ErasedPotential'': The USJ arc goes ''much worse'' here than it does in canon. By the time the dust settles, over half of Class 1-A needs medical attention, with several requiring serious treatment. Shigaraki actually ''succeeded'' at getting his hands on one of the students, partially disintergrating their face, and seriously injured ''himself'' while disintergrating Izuku's eskrima rods, which exploded in his hands -- something he blames Izuku for. On top of all this, the injuries that Aizawa himself incurred are serious enough that he may have [[GameBreakingInjury permanently lost his ability to use his Quirk]].
* ''[[https://archiveofourown.org/works/29573091/chapters/73756062 Prophetic]]'': After the Sports Festival, Izuku comes home to realize the lights he accidentally left on are still on. Looking around the apartment, Izuku notices that none of the chores his mother normally does have been done in quite some time and her entire bedroom is coated with dust. The following chapter reveals that Inko abandoned him some time ago.
* ''Fanfic/OneForAllAndEightForTheNinth'':
** Chapter 40: Not only is Izuku taken by the League of Villains, but he's also hit by a Quirk erasing bullet (a temporary one, thankfully).
** Chapter 42: When All for One tries to steal One for All, Izuku, the Vestiges and the Ennead turn the tables and steal eleven Quirks (including Search and Overhaul) that immediately get added to One for All, while destroying another twenty-three.

* ''Fanfic/EscapeFromTheMoon'': The entirety of chapter six, which reveals the full truth of Doa’s identity and why she’s on the moon... and the source of the voice that she’s been hearing.

* The ''FanFic/PonyPOVSeries'' has several:

* The definite wham chapter of ''FanFic/TheConversionBureauTheOtherSideOfTheSpectrum'' is certainly ''For Whom The Bell Tolls''. It is the single darkest chapter of the story so far, [[spoiler: detailing how Queen Celestia corrupted the TCB!Elements, detailed description of TCB!Twilight's experiments to make the [[MutagenicGoo ponification serum]] work and the '''three thousand''' human test subjects she used to test out the FlawedPrototype versions (topped off with enough {{Squick}}, BodyHorror and NauseaFuel to fill out an entire NightmareFuel page), and Canon!Luna (once she sees the aforementioned) flying into an UnstoppableRage, [[SuperpoweredEvilSide turning into Nightmare Moon]] and charging at the Solar Tyrant herself.]]
* ''Fanfic/{{Misunderstandings}}''
** Raising the Stakes: [[spoiler:The magic Peter has been absorbing has in fact been sent to Earth, which means that a way home for Peter could be possible.]]
** Untethered: [[spoiler:Peter escapes from the Astral Plane, only to discover his connection to Earth has been severed, which means the magic he has been channeling toward will build up inside of him, and unless something is done, Peter will explode in at least three weeks. Now there is a RaceAgainstTheClock, with ponies struggling to find a solution before time runs out and the magic in Peter reaches a critical mass.]]
* ''[[Fanfic/AftermathOfTheGames Integration]]'':
** "Ponies II": Sunset finally returns to Equestria to make peace with Celestia [[spoiler:only to discover she ascended possibly during the Friendship Games and became an alicorn]].
** "Humans IV": [[spoiler:Sci-Twilight is nearly kidnapped by [[TheMafia the human Changelings]]]], which makes everybody realize that there's other humans who know about Equestrian magic and want to use it for their own personal gain.

[[AC:''Manga/{{Naruto}}'']]

* ''Manga/{{Naruto}}'' fanfic ''FanFic/Team8'' chapter 20. [[spoiler:[[DeathByAdaptation Kurenai dies]], which shatters Naruto and causes the team to be officially disbanded.]]
* ''FanFic/AFathersWrath'':
** Chapter 1: [[spoiler:Orochimaru is Naruto's Father.]]
** Chapter 6: [[spoiler: Itachi reveals he knows that Orochimaru is Naruto's real father]]
** Chapter 12: Naruto after using Kyuubi's power [[spoiler: Breaks the Genjutsu placed on him at birth by Sarutobi and his appearance changes looking more like Orochimaru and is taken by him]]
** Chapter 39: Orochimaru find out that [[spoiler: Sarutobi told Minato to seal Kyuubi into Naruto and Naruto is wounded critically by an Akatsuki agent.]]
** Chapter 50: [[spoiler: [[BigBad Keiji Sosano]] takes over Iwagakure and vows to start a Fourth Ninja War where everyone shall worship Jashin]]

* Due to liberal use of the ButterflyEffect, the OriginalCharacter SelfInsert fic ''FanFic/{{Vapors}}'' has several:

* ''Fanfic/DreamingOfSunshine'' has a few:
** Chapter 70: Shikako's near-death in front of her brother in the Gelel arc. Before this, the twins were extremely close and could rely on each other as allies. After Gelel, Shikamaru is convinced that Team Seven's missions are too dangerous and tries to sideline Shikako for her own protection. Shikako--who knows at least part of Akatsuki's plan, and has pretty much dedicated her life to stopping them--is unwilling to let him, and doesn't think Konoha is that safe anyway. The twins have been fighting off and on ever since.
** Chapter 115: Shikamaru loses his arm, on a mission Shikako commanded.
** Chapter 139: Shikako is captured by Jashin cultists and her mission partner Aoba is murdered. Rather than be sacrificed to summon their GodOfEvil into the world, she [[TakingYouWithMe activates her black hole seal]]--which her captors disrupt, causing a massive explosion. The next chapter reveals that said explosion took out ''the entire Land of Hot Springs'', including an occupying force of Kumo ninja, and Shikako herself survived only due to the intervention of her summons. And although tensions have been rising between Kumo and Konoha for at least a year (and ''eighty chapters''), it's this event that finally causes war to break out.
* ''Fanfic/SonOfTheSannin'':
** The climax of Part I's final arc happens in Chapter 40. For starters [[spoiler: Obito/Tobi tricks Sasuke into believing that he ''killed'' Naruto [[MyGodWHatHaveIDone so the trauma]] [[TraumaticSuperpowerAwakening awakens his Mangekyo Sharingan]]. Then goes the InternalReveal of his true identity to Kakashi and the rest of the adult cast, who believed him long dead, and the icing on the cake, the reveal that he brought [[TheLostLenore Rin Nohara]] [[BackFromTheDead back to life]].]]
** Later on, though, this one is topped by Chapter 122. [[spoiler:Madara Uchiha, [[CameBackStrong fully restored to his prime and stronger than ever]], wreaks havoc all over the Second Division as a display of his new power, fighting and defeating the likes of AdaptationalBadasses Hanabi Hyuga (who has the Tenseigan), Itachi and Sasuke Uchiha together (both with Eternal Mangekyo Sharingan), and Rin Nohara (who, aside from being resurrected with Wood Release, learned to use Sage Mode). It's only through the HeroicSacrifice of Maito Gai, who uses the Gate of Death to fight him, that Madara is put out of comission, albeit only temporarily]].

** Chapter 10 starts with news of [[spoiler:Shinji and Gendo having been kidnapped by SEELE simultaneously.]]
** Chapter 11 reveals the Children’s plan: [[spoiler:Rei mind-controls the new batch of MP-Evas. Shinji and Asuka become willing sacrifices to set off their own version of Third Impact. They destroy all original samples taken from Adam and Lilith. Rei seals herself, the Evas, the Seeds and the Spear into a new Moon. Oh, and Asuka is pregnant again.]]

** Chapters 21 and 22: [[spoiler:The Disinfector turns out to be Trafalgar Law, who was in love with Madelyn as a result of her using her Devil Fruit powers. She also used said powers to arrange for Luffy's capture in an attempt to put Law in a better position to reach One Piece]]
** Chapter 30: [[spoiler:Madelyn is actually Mar's mother]].
** Chapter 32: [[spoiler:Madelyn/Blake, Mar and Garreth have, together, the ability to wish the ''One Piece'' world back to normal... but as a result of doing so, Mar's parents will never meet and she will never have been born]]

** Chapter 57 sees [[spoiler: Vivi finally consuming the seed of the Gust-Gust Fruit, making her a Logia.]]

** Chapter 82: [[spoiler: The Revolutionaries intervene at Marineford (with Dragon personally removing Akainu's arm to save Luffy), with the Supernovas also showing up to act as TheCavalry. X Drake intentionally exposes himself as a Marine spy only to then renounce the Marines for real. Blackbeard's crew of Impel Down escapees now includes ''Shiki and Byrnndi World''. Whitebeard [[InSpiteOfANail still dies]], but ''[[SparedByTheAdaptation Ace lives]]'', and he works in tandem with Hawkins to destroy Whitebeard's body before Blackbeard can steal his Devil Fruit powers. Hearing about all this days later when Coo manages to deliver a paper to him isn't enough to stir Cross from his HeroicBSOD, so BROB intervenes directly to reveal that Cross was supposed to die numerous times over, and that saving Merry and Ace was meant to be ''literally impossible'', [[ScrewDestiny but Cross did it anyway]]. This snaps Cross out of his funk, and he declares a RousingSpeech to the whole island about his intent to escape, [[HopeBringer inspiring hope in many of its prisoners for the first time]].]]
** Chapter 85, appropriately titled "Epilogue", is very short compared to the rest of the chapters... except it also has a newspaper article from Apoo and Coo's Free-Feather Report, detailing [[spoiler: Cross' apparent death in Serpent, with the front page even showing his crucified body being burned at a pyre. One person watching the event [[MythologyGag has their arm raised in solidarity, revealing an "X" tattooed on their forearm]].]]

** ''The Incipience''

* The Pokemon fan fic ''FanFic/SpeakUp'' has two: chapters 14 and 20. In chapter 14 [[spoiler: Red realizes his Pikachu accidentally killed Green's Raticate and [[MyGodWhatHaveIDone feels awful about it.]]]] In chapter 20, [[spoiler: Red tries to save Mr. Fuji only for Team Rocket to step in and claim Red abuses his Pokemon. Red tries to tell them otherwise but can't [[PoorCommunicationKills because he's mute.]] In a surprising twist, Mr. Fuji actually ''believes'' Team Rocket!]]
* In Chapter 16 of {{FanFic/Darkfire1220sChallenger}}, Team Rocket attacks the St. Anne with the express purpose of ''murdering Ash and Gary''. After they barely beat Proton, it's revealed he's been toying with them the entire time as Petrel revives his Pokemon and Proton unleashes a ''Hydreigon''. Then a device Team Rocket set up goes off and forcibly evolves hundreds of Magikarp into Gyarados who swarm the ship. Ash barely escapes when he's caught in a Gyarados's horns and ends up in the hospital with severe injuries only to learn that while his friends survive, less than a tenth of the nearly six thousand people on board made it.
* Chapter 23 of ''Fanfic/PokemonResetBloodlines'' implies very strongly that Ash and [[KnightOfCerebus Belladonna]] are half-siblings, and that most, if not all, of the other Ash lookalikes are also his half-siblings.
** And that one falls short to Chapter 34: [[spoiler: Sabrina kidnaps Ash to force him to challenge her gym, and reveals that she knows ''everything'' about him (up to and including his memories of the past timeline). She then proceeds to tell him all she knows about his father and birth circumstances, though she ends up leaving the most important detail out (that he's the ''Bloodline King''). The crowner, however, is that during the fight, Ash ends up creating a Z-Crystal, and immediately uses it to defeat Sabrina's Mega Alakazam with a Z-Move.]]
* ''[[Fanfic/PokemonXDEnigmaShadowSeries Pokemon XD^3: The Waves of Truth]]'': It becomes pretty clear early on that Chapter 21 is a Wham Episode, but you can literally ''feel'' the trajectory of the entire story change the moment the doctor tells Rich that Anabel just miscarried twins that he didn't know about.
* ''[[https://www.fanfiction.net/s/14108691/1/Blasting-Off Blasting Off!]]'':
** Chapter 22 reveals that Blue isn't Professor Oak's grandson; he's his ''great''-grandson. Daisy got pregnant when she was a teenager, only for her boyfriend Gary to abandon her, and was only allowed to come back if she pretended Blue was her younger brother rather than her son.
** Chapter 39: Anyone familiar with the original mod knows that Red is actually a clone. The change is that "Red" is actually a backup clone Oak made and she was originally named Yellow. The original Red ran away and seemingly died in the wild, which is why "Red" started her pokemon journey eight years late: Oak had never bothered training her and needed the extra years to make up for lost time. However, the real Red is still alive, he just happens to be the VillainProtagonist. Lastly, Gary never abandoned Daisy; Oak murdered him because the young man wanted to take the Oak family name when he took on the pokemon league, something that would draw too much attention to Professor Oak.

[[AC: ''VideoGame/RagnarokOnline'']]

[[AC: ''RealPersonFic'']]

[[AC: ''WebAnimation/RedVsBlue'']]

* The fanfic ''[[https://www.fanfiction.net/s/10062463/1/Soulbound Soulbound]]'' starts off innocently enough as an expanded-upon {{Novelization}} of events in the series following the initiation, right up until it gets to the Battle of the Harbor: [[spoiler:Roman's sucker-punch shot fatally injures Ruby, Penny misses most of the fight due to taking Ruby to Weiss, Yang and Blake drive the White Fang off, and Weiss is forced to bind her Aura with Ruby's to revive her.]] The author flat-out stated when it was all over that the fic would be branching off into an AU story.
* ''Fanfic/WeissReacts'': The Cockerel Festival Arc starts off as a relatively normal TournamentArc, until [[spoiler: the reveal that [[BigBad Siegmund Schnee]] plans to make his move during the festival. Several other reveals are made [[HeroKiller involving]] [[BigBad Siegmund's]] [[AbusiveParents actual]] [[WouldHurtAChild crimes]].]]
* During Chapter 42 of ''FanFic/RWBYReckoning'', while Darrel is in a coma, Yang learns from his protectorate Kimba that [[spoiler:his body is Remnant-borne, and that there is some kind of power in his soul.]] Meanwhile, Darrel [[spoiler:discovers the origins of humanity on Earth: Adam and Eve escaped from slavery and a doomed rebellion against their masters, arriving on Earth. Thus, he is descended from the pair.]]

* ''Fanfic/TheChampionAndTheSinger'' is a SugarWiki/{{WAFF}} fic that ships Weiss and Pyrrha together. It's cute fluff until the end of chapter 5, where the White Fang target one of Weiss' concerts and she is shot.

* Episode 65 of ''FanFic/SonicXDarkChaos''. [[spoiler: On the eve of the Demon New Year celebration, Jesus launches an Angel invasion of the galaxy and restarts the Eternal War, killing trillions of innocent people]].

** Episode 74, fittingly titled "''The Mystery Revealed''". [[spoiler: Sonic and friends - and a crippled Tsali - land on Cosmo's devastated home planet Seedrius]]. They soon discover a vault of stolen Demon data files hidden in underground tunnels beneath the same research facility where Tsali was made. [[spoiler: These files reveal that Maledict was literally manipulating ''everything'' in the backstory, from the destruction of the Seedrians to the entire Metarex war, and it was all part of a gigantic GambitRoulette to end the Eternal War and conquer the universe]]. Tsali is so enraged by this discovery that he decides to ally with Sonic and try to go kill Maledict. The Metarex leaders and Dr. Eggman are also captured by Demon special forces.

[[AC: ''Franchise/StarTrek'']]

** And the ''Series/StarTrekEnterprise'' fanfic ''Divergent Paths'' by the same author: thanks to [[spoiler: time-travel]] being well-established in ''Franchise/StarTrek'' canon the [[spoiler:Xindi attack Earth with the ''finished superweapon'']].
** ''And'' chapter three of the ''Franchise/StarWars'' fanfic ''The Unseen War II: Shattered Dreams'' by the same author: Winter, Tycho, Han, Jacen, and Jaina [[spoiler: all appear to have been killed when the ''Millennium Falcon'' was ambushed]].

* The human AlternateUniverse fanfic ''Fanfic/EyesOnMe'' has Chapter 8 where Sapphire receives a NoHoldsBarredBeatdown from her father when he finds out about her being pregnant from Ruby, and it lands her in the hospital. Oh yeah, and then her mother reveals that [[spoiler: they've been thrown out of their house]].

* ''Fanfic/{{Luminosity}}'' diverges from the original ''Literature/{{Twilight}}'' plotline fairly early on, and diverges from it radically some time later, but there aren't really many wham points, just Bella's decisions building. [[spoiler: Then Edward dies.]]
** Then there's the sequel, where we find out [[spoiler: he isn't dead, and it manages to be another Wham, due to what's left of him.]]

* Fanfic/YoungJusticeTitans

* ''Fanfic/LifeOreDeath'' has several.
** ''Episode 4 Learning Experience'' has Ferris almost hospitalize Black Canary after a mistake in a training session. The event psychologically triggers her into a breakdown, and she copes by suppressing her Identity to such an extent that she no longer cares about keeping her secrets, meaning she tells Kaldur about [[spoiler: killing her own eldest brother]]. It's the first big hint most readers have as to exactly how dark her history is.
** ''Episode 17 The Walls'' first has Ferris borrow the Lasso of Truth to make Ultra-Humanite reveal the existence of the Light. Then the Team splits in two groups for two separate missions. Ferris, Robin, Artemis, and Miss Martian end up in Tangiers, chasing after Jackal. [[spoiler: Jackal has kidnapped [[Characters/{{Deathstroke}} Joseph Wilson]] in an attempt to buy back his life from the Light for his failure. Joseph gets his throat cut, and Miss Martian saves Joseph the same way she saved Garfield, suggesting that this may be the birth of Jericho.]]
** ''Episode 25 Childhood's Hour'' is the Season 1 Finale, so it's expected to be big. [[spoiler: When Klarion splits the world, Ferris puts on the Helmet of Fate. She and Nabu decipher the spell craft, get the Team and the League moving to save everyone, then go off to battle and ''kill Klarion.'' Ferris suffers his death curse, though, and collapses as the Helmet falls off of her. Just as the Team rushes over to help her, Wotan, Felix Faust, and Blackbriar Thorn prepare to attack, so Zatanna lunges for the Helmet.]]
* ''Fanfic/WithThisRing''
** At first, the Renegade timeline was just a WhatIf that the author decided to write for a couple of chapters. However, the ill-fated training simulation, in "Contingency" and "Reordered", cements the divergence between the Paragon and Renegade timelines, setting them on quite different paths. The Paragon bonds with the Ophidian and gains [[EnlightenmentSuperpowers orange enlightenment]], while the Renegade instead encounters the Forever Children, steals a Father Box from the Apokoliptian scientist Desaad, and uses it to craft a soul for himself, becoming [[AGodAmI New God of Conquest]] and permanently taking on the identity of Grayven, son of Darkseid. From that point onward, the events of each timeline increasingly don't match up with the other, until eventually they're doing completely different things.

** Chapter 53 ends with the biggest one yet. [[spoiler:Seto is ''sent back down'', rendering all of his progress before null and void]].

!!Other examples

[[AC:''WesternAnimation/AdventureTime'']]
* ''Fanfic/AlexMovieVillain'' has two of these:
** Chapter 4 has, for the first time ever, Marceline is finally called out for her actions by the Candy People when her opponent, the titular antagonist, exposes her actions from "What Was Missing".
** Chapter 10 has Marceline and Princess Bubblegum finding out that Alex has been watching their every move as well as being the BigBad of the entire animated series all along. The biggest wham of this is that Alex [[MoralEventHorizon is responsible]] [[NoodleIncident for their falling out]].
------
[[AC:Literature/{{Animorphs}}]]
* ''Fanfic/{{Daemorphing}}'': ''Welcome Home'' starts with the Yeerks figuring out the Animorphs' identities, so they have to rush to evacuate their families. They save Cassie's family for last, allowing Michelle to get lured into The Sharing and infested by a sub-visser. Then at the end, [[ADayInTheLimelight Tom]] becomes a Hork-Bajir [[ShapeshifterModeLock nothlit]].

Stevie is revealed to be TheMole in the group, Robin is revealed to have willingly joined the Yeerks, and Kyle is saved by the Animorphs and taken to safety.
* ''Fanfic/WhatTomorrowBrings'':
** At first, it seems like this will be a standard PeggySue fic where only the Animorphs were sent back in time, but chapter 6 reveals that [[AscendedExtra Tom]] was sent back as well.
** In chapter 32, Cassie accidentally kills Visser Three, and she realises that Loren is the reason why the Ellimist created the splinter universe.
------

** Arc II, Chapter 16: [[spoiler:Slade finally reunites with the leads after escaping A.R.G.U.S.]].

Kara learns that it is her Aunt Astra who is leading the Fort Rozz forces after meeting her Uncle and Astra's husband Non again, and promptly kills Non as a warning to Astra]].
** Arc II, Chapters 34-35: [[spoiler:The leads finally capture Dr. Wells, who reveals his true identity as Eobard Thawne. Thawne then reveals that there have been changes to the timeline that he was not responsible for, among which include Kara and Kal-El landing together on Earth instead of just the latter at first. He also reveals their superhero names from the alternate timeline, and that Barry will one day marry Iris. S.T.A.R. Labs is then attacked by the remaining Fort Rozz escapees and the metahuman criminals that Barry captured and were imprisoned by A.R.G.U.S. Cisco awakens his powers.

** Arc III, Chapter 43: [[spoiler:A breach opens up in the basement in S.T.A.R. Labs, and spits out Zoom's helmet, much to the confusion of Cisco, Caitlin, and Ronnie, and the apprehension of Barry]].

** The Battle of the Citadel, Parts I and II: [[spoiler:Indo reunites with his wife, Xira, who reveals that the brain surgeons of the Dai Li were originally the servants of the FN Royal Family, and thus it is concluded that Aizo ordered that Zotu's memories of his mother be expelled. The Avatar seizes control of Ain and uses its immense power to demolish the Fire Nation Naval Forces, killing thousands of soldiers. However, as the waterbenders are celebrating their victory, word is received that while the battle was taking place, a legion of soldiers swept through the remains of the Border Forest and up the coast, having claimed nearly all of the Earth Kingdom, aside from Ba Sing Se.]]

[[AC:''Manga/{{Bleach}}'']]
* ''Fanfic/{{Downfall|Bleach}}'' has [[spoiler:Chapter 19. Rukia dies.]] what makes it even more of a sucker-punch is that, up to that point, this AU's differences were[[spoiler: were mostly characters being alive, when they ought to have been dead.]]
------
[[AC:''Series/BuffyTheVampireSlayer'']]
* In chapter 95 of ''[[http://www.tthfanfic.org/Story-28404-95/DianeCastle%2bXendra.htm Xendra]]'', Buffy learns that Faith was being magically controlled ''after'' fatally wounding her. Meanwhile Kennedy is called as the third active slayer.
** The following chapter suggests there might be as many as ''five'' Slayers after Buffy flatlined from forcing Angel to feed on her and Faith flatlined twice while in the hospital. [[spoiler:Turns out there's only three.]]
** While the WhamLine from chapter 152 suggested Xander is now the Key instead of Dawn, 159 shows it's actually ''Xendra''.
-------
[[AC:''ComicStrip/CalvinAndHobbes'']]
* ScriptFic ''Fanfic/CalvinAndHobbesTheSeries'' has "Thunderstorm", which brings in a ''competent'' and ''serious'' villain to a series which has had mostly easily-defeated villains. [[spoiler:What's more, Calvin ''finally'' calls Hobbes out on his [[DirtyCoward cowardice]] with an epic TheReasonYouSuckSpeech. As a result, he actually starts making more of an effort to help.]]
** "Black Rain", being the SeriesFinale, has one [[spoiler: when Slenderman kills Dr. Thunderstorm and Shadow]].
* In Chapter 19 of ''Calvin's Quest'', part of Fanfic/TheOmniverseEvent, Calvin and Hobbes have finally gathered together all six Pillars. However, [[spoiler: as soon as they do so, they are transported to the Paradox Dimension, where they encounter Nivlac, an evil duplicate of Calvin. Over the course of Chapters 19 and 20, it's revealed that the entire Quest was a trap orchestrated by Nivlac to complete the Pillar Mechanism and take Calvin's place in reality.]]
-------

** Chapter 39: [[spoiler: [[MagnificentBastard Grand King Ghidorah]] kicks off his plan. First he goads Monster X into fighting him, and after a short fight, breaks down Kaizer Ghidorah's cage, with the other hunters ForcedToWatch. Then [[BrainwashedAndCrazy Starlight Glimmer]] attacks Junior in Canterlot, not long after she took her sister's Cutie Mark. After luring him back to her village (with Rarity and Night Glider, a member of Starlight’s village who wasn’t in town when GKG kidnapped everyone else), Starlight shows that she’s taken [[WouldHurtAChild Chibi Moon]] hostage. Oh, and then [[FromBadToWorse freakin Nightmare]] [[GrandTheftMe takes over Junior during a moment of weakness.]] The result? Nightmare a.k.a Shin Godzilla.]]

* The ''Manga/DeathNote''[=/=]''WesternAnimation/MyLittlePonyFriendshipIsMagic'' FusionFic ''Fanfic/DeathNoteEquestria'' has chapter 12, which is fittingly styled as a season finale: [[spoiler: Following Ray Painter's death, Rarity suffers severe SanitySlippage until she finally snaps when she deduces that Twilight Sparkle is Kira. She then takes Pinkie Pie hostage and threatens to kill her if Twilight doesn't confess on a live broadcast directed towards L's investigation team. Things spiral out of control, and Rarity ends up actually killing Pinkie while attempting to kill Twilight; when she realizes [[MyGodWhatHaveIDone what she's done]], she [[DrivenToSuicide kills herself]]. And then we find out that Twilight ''engineered this entire sequence of events'' with the power of the Note in order to create a scenario wherein she could earn enough sympathy to be allowed on the team. [[{{Shinigami}} Byuk]] is as stunned as the readers.]]
** How about chapter 14's [[TheReveal reveal]] that the Second Kira is [[spoiler: ''Fluttershy'']], of all ponies, who kills [[spoiler: Sweetie Belle]] to make an example of her.
** Chapter 23's ending strongly implies that [[spoiler: Applejack]] is the Third Kira.
** Then Chapter 25 has L deduce that Third Kira is actually [[spoiler: all ''three'' apple siblings]], and they've been coerced into the role by [[spoiler: Granny Smith's murder]].

** Chapter 29 [[spoiler: has the L Team/Coalition of Justice, with help from Princess Luna, set up a sting to expose the Tri-Kira, in the process ending up having to [[RightHandVersusLeftHand detain Straw Bolt when he unknowingly interferes]]; Rainbow Dash becomes convinced that Twilight is Kira and breaks off from the team; Applejack takes on the Eyes of the Shinigami, but is captured and [[NoHoldsBarredBeatdown nearly beaten to death]] (by ''[[BewareTheNiceOnes Derpy]]'', of all ponies); Mer uses her Death Note to reveal herself to the team, and the cliffhanger suggests that she's restored Twilight's memories and exposed her to the team.]]
** Chapters 30-31 see the resolution of both Twilight's MemoryGambit and the GambitPileup between her, L, and Mer, resulting in the deaths of [[spoiler: Applejack, Big Mac, L, Bon Bon (who turns out to have been a changeling) and Mer]]. Oh, and it turns out there never really was a Fourth Kira, those deaths being set up in advance as part of the GambitRoulette. [[spoiler: Though then one of the Death Notes ends up in Rainbow Dash's possession...]]

** Chapter 25: The implication about the VillainTeamUp is confirmed [[spoiler: Callahan's partner being Captain Smek]]. Furthermore, unlike in their various canons, [[spoiler: Abagail didn't end up in hyperspace, but instead encountered the Boov, the Boov are apparently working for the Gorg, and the Gorg egg container fell through the portal back to Earth]].

* In ''Fanfic/HarryPotterAndTheIcePrincess'', Chapter 29 of Book Two reveals that [[spoiler:Anna has regained her memories of Elsa’s magic and also has magic herself, with the result that she will attend Hogwarts next year; prior to this Elsa didn't know if Anna would show any sign of magic and didn't want to think about it for fear of getting her hopes up]].

** And in the next chapter [[spoiler:Shinji fights Zeruel. Kaji extracts Misato and Asuka from Nerv and takes them to his own batcave. Shinji realized twelve nukes were coming his and the Angel's way so he grabbed Zeruel's and rocketed upwards. The nukes struck them and everyone believed he died.]]
* ''Fanfic/MyLittleAvengers'' has two back-to-back. First, chapter 13 introduces the [[ThePsychoRangers Dark Avengers]], who [[CurbStompBattle effortlessly]] defeat their Avengers counterparts. Then chapter 14 has [[BigBad Loki]] reveal that the ''entire plot'' up to that point was a GambitRoulette, which ends with him [[spoiler: forcing Big Mac to surrender Thor's power]]. This is the story's DarkestHour, and things definitely [[FromBadToWorse worse]] before they get better.

** [[spoiler:[[AlienInvasion Brainiac attacking]]]] and Asuka finding out about [[spoiler:Krypton.]]

* ''Fanfic/{{Paradoxus}}'': Massive wham when Altalune decides to stay in the past and risk it all to eliminate [[BigBad Eudora]] before she kills Bloom (her mother) and Stella. Risky because she is bound to eventually disappear from existence. This is the exact PlotPoint where CharacterDevelopment starts for her and her sister Trisha. The aftermath of this decision marks the start of Trisha's DespairEventHorizon which will lead to her FaceHeelTurn and Altalune's epiphany about who she truly loves and what matters the most which will lead to her trying to save her sister and finally accepting her mother's death. And not only that, but from here onwards, the angst takes off to heart-wrenching levels and doesn't seem to be decreasing soon.

* In the 13th chapter of ''[[http://www.tthfanfic.org/Story-29754-13/ChefJackButler+Origin+Story.htm Origin Story]]'', appropriately entitled "Ragnarok!", the protagonist, who had up until then thought that a male-to-female gender-swapped [[Series/BuffyTheVampireSlayer Xander Harris]] is revealed to be a magically created copy of [[ComicBook/PowerGirl Kara Zor-El]] who merely ''thought'' she was Xander Harris. The stress of this revelation was one of the spurs behind her RoaringRampageOfRevenge against the ''ComicBook/{{Thunderbolts}}''.
* Chapter 86 of ''FanFic/GameOfTouhou'', [[spoiler:Mugetsu's entourage finds Yuugenmagan by chance and kills him, Nazrin, capturing Jaime and thwarting any communication between Queen Byakuren and the House Okazaki, effectively dooming her reign.]]
* ''Fanfic/NecessaryToWin'':
** Chapter 9. Mako’s grandmother is hospitalized and Hana is disowned for doing tankery.

* Chapter 38 of ''[[https://www.fanfiction.net/s/8702285/38/The-Ninth-Sekirei-Pillar The Ninth Sekirei Pillar]]'' reveals the reason for the Sekirei Plan and even the existence of the Sekirei themselves. [[spoiler:Orochimaru created them and the Sekirei Plan to use the Jinki (which are the former Bijuu) to ascend to godhood and remake the world. The Sekirei Plan was so that Naruto would bond to a few, the first causing Kurama to slowly be turned into a Jinki and each following one massively accelerating the process. Furthermore, almost everything Naruto's done, including collecting the Jinki from Orochimaru have been a part of Orochimaru's plan. All he needed was knowledge of how Naruto reversed Causality years prior, which he just gained.]] FromBadToWorse doesn't even begin to cover it.
* ''Fanfic/TheInfiniteLoops'': "The Crash", which was caused by a failed fused loop between the ''ComicBook/MegaManArchieComics'' universe and an unknown universe. [[ExactlyWhatItSaysOnTheTin As the name indicates]], it crashed nearly every single running loop at the time -- the end result was that several new universes were knocked into looping and several new Loopers were Awakened. It was also responsible for creating the ''VideoGame/FusionFall'' fused loop for the Cartoon Network universes.
** ''Fanfic/TheRWBYLoops'': The Tale of Two Sisters, a four-chapter update chronicling Cinder Fall's attempt to Ascend. An army of evil duplicates is unleashed, a set of side characters who had been dying slowly decide to go out fighting (and die permanently without any chance of being restored by loop reset), and Remnant just barely avoids being destroyed. On the positive side, Ruby manages to talk Cinder down and start healing her insanity, Blake takes the opportunity to finally propose to Yang, and four new loopers are activated...
** The Crisis Across The Infinite Loops. Because of one bumbling admin, every loop is set to activate someone, but no one can tell who it is. This forces all the loopers to either kill anyone they don't want to see looping, or risk a very dangerous looper.
* ''Fanfic/AShadowOfTheTitans'':
** Chapter 9 ends with [[spoiler: Jade TakingTheBullet for Jinx, which results in her being left comatose. Susano then throws her body into the Shadow Realm, where Tarakudo intends to use her as a means to escape his prison.]]
** Chapter 10 has [[spoiler: Tarakudo making a [[DealWithTheDevil deal]] with [[EnemyWithin the Queen]] (as Jade's light side is MIA), with the Queen regaining physical form (albeit without hair) and breaking Tarakudo's mask to free him and the Oni Generals, who proceed to [[EvilVersusEvil take over the HIVE]] and create a dome of shadow over Jump City, with a second wave of shadow that repels any beings that aren't normal humans (even ''Superman''), with the intent of covering the entire Earth in shadow so they can drag it into the Shadow Realm]].
** In Chapter 14, [[spoiler: Jade rats out Joker to Batman in order to get out from under him, but after he's inadvertently freed from police custody by the mutated Kitten, he tracks Jade down and proceeds to torture her by [[GlasgowGrin carving up her face]]. The pain causes her to undergo an EmergencyTransformation into a Higher Shadowkhan, turning her into a bird-like creature. She then almost [[StrikeMeDownWithAllYourHatred kills Joker]] before Batman intervenes and sends her fleeing.]]
* In [[https://www.fanfiction.net/s/10546586/1/A-Darker-Direction A Darker Direction]], the storyline for the first season of ''Series/TheVampireDiaries'' seems to be completely in tact before Chapter 14 features a huge curveball when Ben [[spoiler: snaps [[GenderFlip Faith's]] neck after being fed Damon's blood the night before]].
* ''Fanfic/TheSecretLifeOfDolls''' "Paradise Lost". Edward Tallen makes good on his claims that he's dangerous, and kills Ellowyne Two.
* ''Fanfic/TangledAdventuresInArendelle'' has quite a few.
** "Magical Deja Vu" and "The Aftermath" are more in-universe examples, but still count. An ordinary coronation has several oddities happen for the tangled crew, with Rapunzel reacting to something cold when Elsa walked by her, to Elsa's odd habit of rubbing her gloved hands, to Elsa's sudden snappy demeanor when they request creating trade relations between their kingdoms. However, everything changed for them when Elsa revealed her ice powers. Suddenly, they're made aware of a backstory they could never have guessed about, and what began as an ordinary honeymoon is now as much about the sisters as it is about them.
** "Gothel's Gift": The Duke of Wesselton tries to kill Rapunzel, ending on a cliffhanger as she's left out to freeze.
** "Bonds Tested": Eugene and Rapunzel's secrets are revealed, testing the fledgling bonds they'd formed with the sisters (particularly elsa), and essentially throwing the plot sideways from all the drama it creates.
** "Broken": Kristoff gave Eugene a bad sled when he still hated him, resulting in a broken arm.
** "Unwound": Where do we begin? There are no secrets between Kristoff and the others, but it costs him his respect, his relationship with Anna, and eventually he leaves the town in penance for what he did. Elsa meanwhile is showing cracks in her control, putting her kingdom at odds with her yet again after trying to make up with them all. Furthermore, this chapter lead to a temporary breaking of relations between the humans of the 2 casts, angry at the events that unfolded.
** "Promising Princesses Part 2": After an ordinary day trying to make up with each other, Sven bursts in and reports that Kristoff is missing.
** "The Clock Strikes Eleven": We get an expanded origin about Rapunzel's magic flower, hints that her powers are still returning further, and even an idea that Anna really did die on the fjord, restored to life by Elsa's love. Also, Rapunzel and Anna finally bury the hatchet, hopefully for good, and we find out that Rapunzel is actually the youngest of the females despite being the first to get married.
* ''Fanfic/TheNextFrontier'': [[VideoGame/KerbalSpaceProgram Kerbin's]] first FTL spacecraft has been quietly hanging around on the outer edge of a solar system they know to contain intelligent life, [[AliensStealCable recording stray satellite TV broadcasts]] to learn a bit about their new neighbours, and are doing some ice mining on a small asteroid to top off their reaction mass. Jeb's on EVA setting up the drilling rig, trading idle banter over the radio... and then [[OOCIsSeriousBusiness Bob uses a real swearword]] and everyone goes into panic mode because a local ship just entered detection range. And then the point of view shifts, and the readers finally find out just what this story is a crossover ''with''...
* ''Fanfic/TheReactsverse'':
** The [[Fanfic/WeissReacts Best]] [[Fanfic/LucinaReacts Reactsverse]] Crossover has one, the chapter 'Serial Escalation'. [[spoiler: It reveals that [[{{Yandere}} Tharja]] simply [[IJustWantToHaveFriends wants]] [[IJustWantToBeLoved to be loved]] by the first person to ever show her respect, [[SingleWomanSeeksGoodMan Robin]]. It also reveals the ''[[GoodFeelsGood true]]''' reason Velvet acts like a ClingyJealousGirl...]]
* The ''VideoGame/MassEffect''/''VideoGame/SwordOfTheStars'' crossover ''Fanfic/ShepherdOfTheStars'' has a few, with the two largest actually [[LampshadeHanging lampshaded]] by removing the notations that say if a chapter is a Codex or Story entry. All have had serious effects on the chapters that followed, with the second even kicking off its own arc.
** The first is when [[spoiler:the Ghost Ship arrives at Thessia under Benezia's insane control and bombards it with antimatter missiles.]]
** The second comes when [[spoiler: the Peacekeeper Enforcer enters Turian space and immediately begins tear its way through their fleets.]]
* ''Fanfic/ThousandShinji'': Chapter 14, where several flashbacks reveal Shinji's plans going badly wrong. In few words: [[spoiler:Asuka and Rei broke their friendship off after a brutal fight, Touji got crippled, Hikari got killed, Kaji got assassinated, Rei died several times, Asuka was in a coma after being mind-raped and Misato was under arrest after killing Ritsuko.]] Some reviewers claimed that he was screwed over even worse than in canon.
* ''Fanfic/OutOfTheCornerOfTheEye'':
** Chapter 5 has Shendu first reach out to Jackie to try and [[EnemyMine form an alliance]] against the Outer Gods. More importantly, in the final scenes, [[spoiler: Paco reveals he's [[DealWithTheDevil cut a deal]] with Hsi Wu for [[YouKilledMyFather revenge on Guerra]]; upon its completion, Paco and Hsi Wu are [[FusionDance fused together into a new being]]]].
** Chapter 12 reveals that Uncle's brother Jie (Jade's grandfather) was involved in the [[ReligionOfEvil Whateley Project]], and also that [[spoiler: [[VillainTeamUp Bai Tza has allied with the Deep Ones]]]].
** Chapter 13 hints that Uncle's DarkSecret has something to do with his brothers. The Chan Clan are forced to witness Barnabas Marsh and [[spoiler: Bai Tza]]'s wedding (officiated by Dagon and Hydra), giving them a taste of [[EldritchAbomination just what]] they're up against. And in the final scene, [[spoiler: Nyarlathotep reveals that Jade is actually a human/Thousand Young [[HalfHumanHybrid hybrid]]]].
%%* Luigi's World in ''VideoGame/BrutalMario'', which signals the change from a lighthearted MegaCrossover to a dark storyline.
* ''Fanfic/GuardiansWizardsAndKungFuFighters'':
** Chapter 11 is a smaller scale one, mostly being a setup chapter for the Rebellion's attack on Torus Filney. But near the end, there are two major twists — [[spoiler: Drake, one of the Rebellion's more levelheaded leaders, is actually [[TheMole Cyrus Ludmoore in disguise]]. Which is revealed as he seemingly kills [[PunchClockVillain Tynar]] by feeding him to Sandpit, long before he can make his canon MookFaceTurn.]]
** Chapter 19 starts off looking like a BreatherEpisode dealing with everyone recovering from the climax of the Dark Hand arc, but then there are several twists in its final scenes: [[spoiler: Cornelia's father Harold is an immortal, who helped found the Dark Hand (which [[RunningBothSides secretly runs]] Section 13) as part of a gambit to get Earth's governments to start using magic, [[WellIntentionedExtremist to protect the world from other worlds]]. Oh, and Harold's original identity centuries ago? ''King Arthur''.]]
** Chapter 22 sees Tarakudo force Oni masks on Jackie and Viper, [[TheCorruption corrupting them]] into fighting the other heroes [[spoiler: as a distraction while he steals the Hana Fuda cards]]. And as a result of this fight, [[spoiler: Matt and Alchemy learn about the Guardians' and Jade's powers]]. Meanwhile, [[EvilVersusEvil Nerissa tries to eliminate Wong]], but while this ends in a stalemate, it allows her to steal his potion for making Shapeshifters. [[spoiler: It's also implied that the Master of the [[EldritchAbomination Cavalcade of Horrors]] somehow [[RippleEffectProofMemory knows about]] the MergedReality]].
** Chapter 24 sees Wong finally makes [[TheStarscream his move]] against Phobos. In the end, [[spoiler: he's betrayed by Cedric, Miranda and [[MookLieutenant Roberta]] and left mortally wounded, forced to flee. Taking advantage of his desperation, Ludmoore is able to trick him into accepting a deal to save his life, but which results in Ludmoore [[DePower stealing all of Wong's magic, Talismans included]]. With no other options, Wong returns to Earth and [[VillainTeamUp allies]] with a Jiangshi, becoming its student and a vampire himself.]]
** Chapter 29: [[spoiler: Drago]]'s plan to escape from [[TheAlcatraz Cavigor]] causes the fortress to collapse; [[MisplacedRetribution blaming the Guardians for this]], and the subsequent [[AFatherToHisMen deaths of her men]], Sidriss swears revenge. Meanwhile, the collapse also allows the Guardians to [[spoiler: take Cedric prisoner after he's knocked out by debris.]]
** Chapter 31: The [[BigBadassBattleSequence Battle of the Meridian Plains]] results in [[spoiler: the nobility's army being crushed and their leaders made to surrender]], while at the Castle [[spoiler: Jackie [[TalkingTheMonsterToDeath convinces]] Tristan to abandon his hatred and [[HeelFaceTurn switch sides]]]]. However, these {{Hope Spot}}s are then crushed as [[spoiler: Phobos manages to steal Elyon's power for himself, becoming a PhysicalGod]].
** Chapter 32: [[spoiler: Phobos transforms the Whisperers into new {{Mooks}} and [[YouHaveOutlivedYourUsefulness unleashes them on the Guards]], leading to an EnemyMine between them and the Rebellion. Drake/Cyrus shapeshifts into his Beast form to join the fight. Nerissa intervenes to take Roberta out of the fight. Caleb overuses the Sword of Thanatos for the fight, and is fully corrupted by it. And the chapter ends with [[HeroKiller Phobos killing Uncle]].]]
* ''Fanfic/CitadelOfTheHeart'': It's a common practice by the author to have a KnightOfCerebus debut at around Chapter 12-14 who changes everything known prior in the fic, as to emulate the very first WhamEpisode in the continuity.
** The above refers to ''Truth and Ideals'' Chapters 12-14 which is the debut of a Lucario named Regulus. At first sounds normal, except a few things. 1; the only Non-Unova Pokémon to appear thus far is a Pichu, which is a given considering the lead protagonist is Ash. 2; Lucario is ''nicknamed'', something that one of Ash's Pokémon would never have. 3; he carries with him [[VideoGame/PokemonXAndY a Key Stone and Lucarionite]], meaning he has long since been capable of [[SuperMode Mega Evolution]]. 4; not only can he telepathically communicate with Ash, but he's shown very quickly to be very much prone to extreme hostility and knocking Ash unconscious for a few days straight, and actually ''unnerves'' N when the two meet. Lastly, 5; [[spoiler:because of the fact Ash has his AuraVision inherited from his unknown father, and the fact Regulus was a former Pokémon of his, Ash ultimately resolves the arc by catching Regulus and taking him along with him for the journey, which then proceeds to make ''every'' future gym battle Ash has to face next using a very beefed-up team from the teams they had in the games.]]
** Chapter 13 of ''Sword Art Online: Special Edition'', we finally get to see who Chronicler's ''real'' dad is, and it isn't exactly pleasant for ''anyone''. [[spoiler:Imagine a guy with the general appearance and clothing of [[WesternAnimation/EdEddNEddysBigPictureShow Eddy's Brother]], now imagine him as be virtually [[NighInvulnerable indestructible]], incredibly ''[[SuperStrength strong]]'' and capable of extremely fast [[TeleportersVisualizationClause line-of-sight teleportation]] coupled with supernaturally keen vision. Next take into consideration Chronicler is a [[SemiDivine demigod]], meaning one of his parents is a full-fledged god; Grandis both outright states, as well as by all means shows in the next few chapters, that he's indeed a full-on PhysicalGod. What results is just about everyone in the cast freaking out because of the sheer OutsideContextProblem Grandis poses which ultimately results in Grandis heavily brutalizing Chronicler, traumatizing Nobuyuki, making Ken ''even more'' paranoid, and having every other person in the cast completely clueless as to how to process the fact the guy ''exists''.]]
** Considering ''Digimon Re: Tamers'' has ''two'' of such characters appearing in a short span of time from each other, Chapter ''8'' is when this character properly appears. [[spoiler:Devimon and Taomon find themselves face to face with an Ultimorian Deity named Darigus, who much like Grandis above, presents an OutsideContextProblem that causes Taomon [[OOCIsSeriousBusiness to try and find Guilmon and Terriermon first to use Trinity Burst against it]], and everything slowly but quickly converting into a FireAndBrimstoneHell because of various bodily material from Darigus being shed with each attack against him, and while the Digimon characters are just fine, the human characters are half-way transformed into stone and unable to do anything. While Darigus is ultimately defeated with some additional assistance from Grandis, Chapter 9 reveals the aftermath of Darigus' appearance [[DespairEventHorizon damaging Ruki's sanity]] because Darigus just ''barely'' was stopped from ''flat out murdering Ruki'', [[GodzillaThreshold Monodramon Warp Digivolving into Millenniummon to deal with an adversary]] [[TheWorfEffect which easily curb-stomps him before he can successfully trap it]], and Ruki and Ryo both deciding that the DomesticAbuser of Ruki's mother finally needs to be gone with the implication that they would rather ''[[OOCIsSeriousBusiness outright kill him]]'' than try and jail him.]]
* ''Fanfic/LelouchOfTheWingsOfRebellion'':
** Chapter 33, "Blooming Villain": [[spoiler:Shirley sees Lelouch and the Knights leaving the Metaverse, with Milly throwing an errant line that reveals them as the Black Knights. This, combined with seeing Lelouch falling for Kallen, causes her to form her own Palace over Ashford in the Metaverse, and given how much repressed jealousy she has, [[NotHisSled it's likely she will NOT accept her shadow]].]]
** Followed by "Tanabata", that ends in with a series of startling revelations: [[spoiler:Shirley has a Palace, she represents the [[SevenDeadlySins Deadly Sin]] of {{Lust}}, the Black Mask works for someone that sounds and acts as V.V., they know who the Black Knights are and where to find them, and the only reason they haven't killed or captured Lelouch yet is because ''Emperor Charles'' decided that Lelouch will serve their objectives better if [[INeedYouStronger he's left alone to grow into a stronger Persona user]].]]
** Chapter 41, aptly named "Revelations". Hoo boy, where do we even start... [[spoiler:Mao [[DisneyDeath survives Shirley's Palace]] and comes back to kidnap Nunnally. Lelouch is [[InternalReveal forced to come clean]] to Sayoko about the Metaverse in order to recruit her help. Lelouch loses the rematch fight against Mao, but two members of the Irregulars [[BigDamnHeroes save his life]]. The two Persona Users turn out to be Nunnally's suspicious friend Alice and ''Nunnally herself'', who not only has been visiting the Metaverse in secret just like her brother, but is also able to ''[[DisabilityNegatingSuperpower see and walk]]'' in there. Then Lelouch decides to straight-up murder the knocked out Mao, but [[{{Pacifist}} Nunnally]] strongly opposes him. Alice, however, completely agrees with Lelouch that there's really no other choice and [[CoupDeGrace puts a bullet in Mao's heart]] [[DoubleTap and head]] before the siblings can stop arguing. ''And then'' the Black Mask arrives, thanks them for killing Mao for him, and reveals he's a ''government-sanctioned ProfessionalKiller'' who triggers mental shutdown on Britannia's orders. He also says the only reason he hasn't killed the Black Knights and the Irregulars is because he's yet to receive an official order to do so, but warns them that he will eliminate them if they cross paths with him in the Metaverse again. As a parting gift, the Black Mask also reveals he's ''not'' the same "Black Mask" Clovis was talking about before the prince got KilledMidSentence, meaning there's ''another'' SerialKiller using the Metaverse to commit murder with impunity.]]
