[[folder: ''Franchise/Alien'' ]]

* While it was made in 2007, [[https://www.youtube.com/watch?v=RXaCZe2xZkM this recut trailer]] of ''Aliens'' proved to be [[Film/{{Avatar}} eerily prophetic]].

[[/folder]]

[[folder: ''Literature/Animorphs'' ]]

* ''Fanfic/AllAssortedAnimorphsAUs'': In "What if they saved Jake's family?", the Animorphs come up with a plan to get Tom's Yeerk to leave his host, then Tom crushes the Yeerk in his fist as soon as it exits his ear. A few years later, [[spoiler:Rachel]] would do the same thing in ''[[Fanfic/{{Eleutherophobia}} How I Live Now]]'' by the same author.

[[/folder]]

[[folder: ''Film/Avatar'' ]]

* ''Fanfic/AvatarsIIWhenQwaritchTakesRevenge'' begins with Quaritch(or Qwaritch, as the fic calls him) returning, since the fic refuses to accept that he died in the movie. ''Film/AvatarTheWayOfWater'' has Quaritch's consciousness implanted in a Na'vi body, enabling him to return and reprise his role as a villain.

[[/folder]]

[[folder: ''Western Animation/Avatar The Last Airbender'' / ''Western Animation/The Legend Of Korra'' ]]

* The first popular ship from ''WesternAnimation/TheLegendOfKorra'' was shipping Korra with Yue (from ''WesternAnimation/AvatarTheLastAirbender''). A lot of fanart existed for the pair prior to the release of the series, despite (or because of) it being a crack ship. The actress that played Yue in the LiveActionAdaptation ''Film/TheLastAirbender'' voices Asami in ''The Legend Of Korra''. The two were initially stuck in a love triangle involving the same boy, but [[spoiler:the triangle broke up]] by the end of Book 2. At the [[LastMinuteHookup end of the series]] [[spoiler:Korra and ''Asami'' end up the OfficialCouple.]]
* This [[http://booter-freak.deviantart.com/art/Avatar-LOK-Discovers-Shipping-311589894 piece of fanart]] for ''The Legend of Korra'' depicts several characters discussing their reactions to fan pairings involving them. Panel 4, where [[spoiler: Asami is trying to convince her father that there's nothing going on between her and Korra]] is hilarious if you've seen the show's finale. It even gets [[LampshadeHanging lampshaded]] [[http://booter-freak.deviantart.com/art/Avatar-LOK-Discovers-Shipping-Season-4-506429170 in the last panel for the follow up fanart of Book 4]].
* A hilarious moment for the GrandFinale moment of ''The Last Airbender'' comes from a piece of fan art called "[[http://fc01.deviantart.net/fs30/f/2008/072/b/b/How_we_roll_by_alexds1.png How we roll]]," Zuko [[WhatTheHellHero complains to the heroes for sitting around doing nothing while his evil relatives plot]]. Four months later, the GrandFinale airs, and Zuko's doing the exact same thing.
** Go Devil Dante's Flash [[https://www.youtube.com/watch?v=5dN0JUBpCXI Zuko Dance]] is even funnier in the wake of the Earthbender [[https://www.youtube.com/watch?v=Jau77pwpvkk Pebble Dance]] in the LiveActionAdaptation.
* ''FanFic/TheStalkingZukoSeries'' has tension growing between the Northern and Southern Water Tribes, with North viewing the South as uneducated yokels and the South view the North as stuck-up busybodies who didn't lift a finger to help them when they facing genocide from the Fire Nation. Then Season 2 of ''WesternAnimation/TheLegendOfKorra'' comes out...

[[/folder]]

[[folder: ''Franchise/Barbie'' ]]

* In Creator/SamAndMickey's Oscar-spoofing "Award Show," Barbie expresses frustration that since her ''Finding Nemo''-inspired porno didn't qualify for any Doll Actor's Guild Awards, she won't get to sing "Touch My Boat" live at the ceremony, [[spoiler:and spitefully hijacks the In Memoriam sequence to play the original clip]]. After "[[Film/Barbie2023 I'm Just Ken]]" received a Best Original Song Oscar nomination, Creator/RyanGosling and his living Ken chorus fulfilled the thought of Creator/{{Mattel}} dolls singing live at an award show.

[[/folder]]

[[folder: ''Franchise/Buffyverse'' ]]

* During his JourneyToTheCenterOfTheMind in ''[[https://www.fanfiction.net/s/9663877/35/And-Another-Thing-I-Hate-About-You And Another Thing I Hate About You]]'', [[Series/BuffyTheVampireSlayer Xander and Cordelia]] had to travel through and experience events that had a major impact on him (though out of sync with each other). Xander made a habit of grabbing whichever Cordelia he came across and kissing her stupid. He and Cordelia would also at times help out, thinking everything was a memory so they weren't actually affecting anything. Once they're back in the real world, Buffy mentions that [[RealAfterAll for the past few years Xander would show up in places he shouldn't be or places he already was]].

[[/folder]]

[[folder: ''Comic Strip/Calvin And Hobbes'' ]]

* Rupert and Earl's crew from ''Fanfic/CalvinAndHobbesTheSeries'' [[TrademarkFavoriteFood love peanut butter milkshakes]]. In 2012, Denny's introduced a peanut milkshake as part of a promotion.
** Calvin calls ComicBook/HarleyQuinn [[Webcomic/{{Homestuck}} "Hardly Quinn".]]
** The film ''Free Birds'' has the same premise as "Calvin, Hobbes, and the Pilgrims".
** Two for "Wild Movie":
*** One of Calvin's ideas for a movie is ''Tornado Sharks'', which is almost ''exactly'' what the 2013 MadeForTVMovie ''[[http://en.wikipedia.org/wiki/Sharknado Sharknado]]'' is about.
*** Also, the sequel's name, as proposed by Calvin, is ''Tornado Sharks 2: I Think Things Just Got a Little Windier''. The sequel to ''Sharknado'' [[http://www.cnn.com/2013/08/08/showbiz/movies/sharknado-sequel-title-ew/index.html was named]] the equally stupid ''Sharknado 2: The Second One''.

[[/folder]]

[[folder: ''Franchise/Castlevania'' ]]

* In a ''Franchise/{{Castlevania}}'' fanfic called [[http://www.fanfiction.net/s/3323568/1/Castlevania_Wisps_of_Dracula Castlevania: Wisps of Dracula]], Simon's son was "dead of the skick". While a slight spelling error, it becomes a very funny joke to ''Franchise/SuperSentai'' fans when considering the [[Series/TensouSentaiGoseiger Skick Tribe]].

[[/folder]]

[[folder: Crossover ]]

* The [[FanVid AMV]] ''Anime Academy Heroes'' had [[Anime/FullmetalAlchemist2003 Edward Elric]] piloting a Franchise/{{Gundam}}. Then, the director of ''Anime/FullmetalAlchemist2003'' went on to direct ''[[Anime/MobileSuitGundam00 Gundam 00]]''.
* In the MassiveMultiplayerCrossover fanfic ''[[Fanfic/EyesOnMe Be Wherever You Are]]'', a humanized Arthur Read is depicted as a college professor teaching at Rutgers, the university [[WesternAnimation/StevenUniverse Ruby and Sapphire]]'s granddaughter Hope is currently attending. Six months after the fanfic was first published, the DistantFinale of ''WesternAnimation/{{Arthur}}'' aired, and [[spoiler:one of the characters was actually shown to be a college professor (though it's Buster who has the job, not Arthur)]].
* ''Fanfic/DReincarnation'' is about the Devil-Fruit users from ''Manga/OnePiece'' reincarnated as ponies as ''WesternAnimation/MyLittlePonyFriendshipIsMagic'', with Luffy reincarnating as [[{{Cloudcuckoolander}} Pinkie Pie]]. This becomes hilarious in the Wano arc of ''One Piece'' [[spoiler:where Luffy's Awaken Devil Fruit power gives him ToonPhysics akin to what Pinkie uses]].
* Back in 2001, an author named [[https://www.fanfiction.net/u/50988/Kanius Kanius]] did Digimon Fusion (Digimon characters play the roles of DBZ) and is doing a remake called [[FanFic/DigimonFusionKai Digimon Fusion Kai]] around 2010. Comes 2013, that the english version of [[Anime/DigimonFusion Digimon Xros Wars]] is titled 'Digimon Fusion'.
* In ''Fanfic/TheGreatStarshipBattle'', Chewbacca dies and is later resurrected. In 2014, the year after the story was written, the Franchise/StarWarsExpandedUniverse was rebranded as ''Franchise/StarWarsLegends'' and declared to be non-canon. This meant that Chewbacca's death in the novel ''Vector Prime'' was essentially undone and he subsequently appeared alive and well in the Sequel Trilogy.
* From the ''Fanfic/HalloweenUnspectacular'' series:
** In the first chapter of the first collection, [[WesternAnimation/DannyPhantom Danny, Sam, and Tucker]] express their belief that [=E350=] is going to fail to complete his self-imposed Halloween challenge (to do one chapter every day of October). Considering that there ultimately ended up being ten collections in the ''Halloween Unspectacular'' series, this comes off as extra hilarious.
** One of the "Twenty Terrible Theories" in [=HU6=] is that [[spoiler: [[WesternAnimation/StevenUniverse Rose Quartz was Pink Diamond]]]], with [=E350=] being exasperated by it. Two years later, this theory was confirmed by canon.
** The main villains of [=HU3=] are the Witchfinder-Generals, who are shown to go after any magic, regardless of the harm destroying it will cause. [=E350=] would later start writing fics for ''WesternAnimation/TheOwlHouse'', which revealed that main villain Emperor Belos [[spoiler:is a witch hunter who wants to wipe out the Boiling Isles simply because they use magic, regardless of the harm it would cause.]] Building on this, he reveals that [[spoiler:he actually wants to be called a Witch-''Hunter'' General.]]
* In chapter 25 of the ''Anime/LoveLive'' / ''Manga/JojosBizarreAdventure'' crossover ''Fanfic/HonokasBizarreAdventure'', Umi had updated the training chart from the episode "No 'Senpai' Allowed" to include an hour and a half of Stand sparring. The sequel to the anime, ''Anime/LoveLiveSunshine'', reveals that Dia had acquired the same training chart Umi that made so Aquors can use it to prepare for Love Live. Unless Aquors also has Stand Users, the new group of idols is going to be really confused.
* In Chapter 77 of ''FanFic/Hottie3TheBestFanFicInTheWorld'', which involved {{fusion|Dance}}, all three [[WesternAnimation/StevenUniverse Crystal Gems]] fused into one being. A few months later, the ''Steven Universe'' episode "Giant Woman" aired on TV and established that Gems have the ability to fuse with others. Even better, they would fuse together for real into Alexandrite in another episode, and it was revealed late in the first season that Garnet is a fusion herself.
* ''Fanfic/HuntersOfJustice'' (Franchise/TheDCU & ''WebAnimation/{{RWBY}}''):
** The Condiment King who appears in the story is a CompositeCharacter between his comic book name and his original DCAU incarnation, and a version of Condiment King exactly like that debuted in ''WesternAnimation/HarleyQuinn2019'' a few months later.
** On chapter 40, the Bat-family faces Clayface, King Shark, Dr. Psycho, and a brainwashed Ren and Jaune, who were being controlled by Poison Ivy. A few weeks later, also on the ''Harley Queen'' series, Dr. Psycho enhances his powers and mind controls Clayface, King Shark ''and'' Poison Ivy.
** The existence of this story itself now that there'll be an actual ''RWBY/Justice League'' crossover in April 2021.
* ''Fanfic/MoxxieMorningstar'' (''WebAnimation/HazbinHotel'' and ''WebAnimation/HelluvaBoss''): The fic's premise revolves around Moxxie being raised as a prince of the Morningstars (the most wealthy and powerful family in Hell), eventually leaving, and his adopted father forcing him to return to the family. A couple years later, the episode "[[Recap/HelluvaBossS2E3ExesAndOohs Exes and Oohs]]" would reveal that Moxxie's canonical backstory involves him growing up in and eventually leaving an influential mafia family in the Greed ring, while the episode's plot involves his biological father trying to force Moxxie to go home.
* ''Fanfic/NecessaryToWin'' (''Anime/GirlsUndPanzer'' & ''Manga/{{Saki}}''): In Chapter 7, Yukari [[TheInfiltration infiltrates]] Anzio, which, instead of Saunders, is Oarai's first opponent. In the Anzio OVA, she ends up infiltrating Anzio as well, but unlike in the fic, doesn't get caught.
* ''Fanfic/TheOwlAndTheFrog''
** "Chapter 33: Maddie, Marcy and Luz" reveals that a wind glyph was created by [[spoiler:Sheresade]] when she visited the Boiling Isles and met Philip Wittebane. " In [[Recap/TheOwlHouseS2E15ThemsTheBreaksKid Them's the Breaks, Kid]]" (which aired a few weeks after the chapter's publishing), Luz discovers a glyph combo for wind.
** Shuffollower complained in a review for Thomas Holmes' canonized story "Premonition" that with how slowly the story is updated, it'll likely take [=ChampionElCid=] two more years to finish the story after Arc 5 was completed. Champion outright confirms this in the author's notes at the end of "Froggy Little Christmas".
* ''Fanfic/RisingOfTheSleepingSoldier'' (''WesternAnimation/Castlevania2017'' & ''Literature/TheRisingOfTheShieldHero''): When Alucard explains what he world was like to Ren, Itsuki and Motoyasu, Motoyasu thinks that Alucard's friends Trevor and Sypha are his harem, only for Alucard to tell him that they are both men just to mess with him. This leads to Motoyasu [[MistakenForGay thinking that he's gay]]. [[spoiler:Both WordOfGay and Season 3 of the show confirms that Alucard's canon counterpart is bisexual.]]
* ''Fanfic/TheSearchForVictory'' is a crossover between the Franchise/StargateVerse and the Franchise/MarvelCinematicUniverse written in 2014 (the author specifically states that this continuity disregards the events of ''Film/GuardiansOfTheGalaxy2014''). One element of this crossover features Carol Danvers as a pilot in the F-302 program, years before ''Film/CaptainMarvel2019'' would introduce the MCU Carol Danvers as a test pilot for a government program using alien technology before she received her powers.
* ''Fanfic/ShinnenNewYear'': Somewhat an inversion of ascended fanon. The English dub version of ''Anime/GuiltyCrown'' in the final episode's epilogue, the casts last words are "To the New Year!", then co-authors are doing this mega crossover fanfic based on New Years Eve.
** Then plays straight in other parts. In Chapter 8, Captain Ginyu mentions his thanks of Freeza getting back his own body back. I wonder what happened officially in ''Anime/DragonBallSuper''?
** Chapter 1 has Kirito mention himself being ''WesternAnimation/SamuraiJack'', alongside the Minions of Set appears and Arago's super form looks like Aku. Then, Adult Swim renews the cartoon for 2016.
** Chapter 32 shows the Powerpuff Girls (2016 versions) siding with the Green Lanterns (John Stewart, Razer, and Aya). Promos of ''WesternAnimation/ThePowerpuffGirls2016'' show the girls creating similar constructs.
* ''Fanfic/TimeAnomaly'';
** During Tony and Steve's time in the past, the two bond with the Williams family (''Series/DoctorWho''). When ''Film/AvengersEndgame'' aired, one of the earliest scenes was Tony bonding with Nebula, played by Creator/KarenGillan.
** Since this fic was written, the MCU version of Kang the Conqueror has been introduced in ''[[Series/Loki2021 Loki]]'' and ''Film/AntManAndTheWaspQuantumania'', both of which established that there are multiple alternate versions of Kang in existence in the multiverse. With this in mind, where the Kangs depicted in the MCU have been considered the most dangerous ones, such as He Who Remains controlling time to allegedly stop the creation of his worse variants and the Conqueror believing that he has to destroy his counterparts to stop their own devastation, it's tempting to theorise that the Kang depicted here is basically the dumb counterpart, who ''thinks'' he's a genius but doesn't know enough to realise that his plans, methods and technology are flawed at best.
* An ''Manga/DragonBall Z'' and [[RealPersonFic Anne Frank]] crossover fanfic, ''Fanfic/UntilTheEndOfTime'', had UsefulNotes/AdolfHitler going Super Saiyan. Cue ''Manga/TheLegendOfKoizumi'' and the "Legendary Super Aryan".
* ''[[https://www.fanfiction.net/s/13336479/ A Very Scary Thought]]'' (incomplete, author DiedDuringProduction): [[WhatCouldHaveBeen Before]] [[DiedDuringProduction his death]], Jim Bader was going to make Ranma and Nabiki’s next child be an {{Expy}} of [[Manga/FairyTail Erza]], this time with Nabiki as the [[Anime/{{Vandread}} Fama]] and Ranma as the [[MisterSeahorse Ouma]]. When Erza’s mother Irene Belserion is finally revealed, she is a voluptuous redhead who used to be known as the Dragon Empress. To be more specific, Ranma’s ability comes from forming a pact with [[ElementalEmbodiment five Elemental Dragons]].
* The now-deleted ''[[https://www.fanfiction.net/s/11348911/1/RWBBYVerse-Clash-of-Heroes RWBYverse: Clash of Heroes]]'' crossover had [[WesternAnimation/{{Ben 10}} Ben Tennyson]] and [[WebAnimation/{{RWBY}} Yang Xiao Long]] [[BattleCouple as a]] [[CrossoverShip couple]] and they got along pretty well. Then Volume 3 of ''RWBY'' arrived and Ben's (post-timeskip) voice actor, Creator/YuriLowenthal, became the voice of Mercury Black and he and Yang are enemies.
* The training Ranma gave Vegeta in ''Human Saiyajin'' is pretty much the same training given to him by Whis is ''Anime/DragonBallSuper''. I.e showing him how to overcome the DBZ universe’s UnskilledButStrong approach to martial arts by training him how to better control his ki and body.
* In the ''VideoGame/{{Splatoon}}''/''WesternAnimation/TotalDrama'' crossover, ''[[https://www.fanfiction.net/s/13514051/1/Three-Stays-Fresher Three Stays Fresher]]'', since the Squid Sisters are a trio, there are three way Splatfests, with each girl championing a team. Come ''VideoGame/Splatoon3'' and three way splatfests (as well as a three person idol group) are introduced. The author admitted to actually being blown away by this, admitting that they never thought it would happen for real.
* The ''Fanfic/TheInfiniteLoops'' has several.
** ''Naruto Loops:'' Even in the original Innortal loops, Naruto and Kurama manage to become friends as time goes on. Fast forward to the later arcs in the Manga, where they actually ''do'' manage to become something resembling friends. (Albeit, Kurama is a bit of a {{Tsundere}} about it...)
** One of the first ''Franchise/{{Kirby}}'' loopers was Marx, who, at the time he began looping, was currently still dead. Cue ''VideoGame/KirbyStarAllies'', which not only revived Marx, but also had him do a HeelFaceTurn, much like he had in the loops.
** In the ''VisualNovel/DokiDokiLiteratureClub'' Loops, Monika and Natsuki bet that if sexy Bowser became a meme, they'd have to become bad Sonic OCs for a Loop. At the time, it was obviously not going to happen due to the obvious niches a sexy Bowser could be... And then ''JustForFun/{{Bowsette}}'' happened and the two had to follow through.
** In one ''VideoGame/FiveNightsAtFreddys'' loop, Mike stops the owners of the restaurant from putting the animatronics in 80s themed outfits. Then comes ''VideoGame/FiveNightsAtFreddysSecurityBreach'', which has the ''very'' 80s themed Glamrocks. Seems like the owners didn't listen.
** One ''VideoGame/XenobladeChronicles2'' snip reveals that Rex decided to date both the Aegis girls as well as Nia. Come ''VideoGame/XenobladeChronicles3'' and it turns out that's exactly what he ended up doing in canon. With at least one child per girl, as well.
* In the ''VideoGame/MegaMan'' and ''Franchise/{{Pokemon}}'' crossover [[https://www.deviantart.com/slurexe/gallery/443092/megamon Megamon]], Mega Man is transformed into a Vaporeon. The two of them would eventually be the unlockable characters in ''VideoGame/SuperSmashLand''.

[[/folder]]

[[folder: ''Franchise/Danganronpa'' ]]

* ''Fanfic/DespairsLastResort''
** The author notes that ''VideoGame/DanganronpaAnotherEpisodeUltraDespairGirls'' also happens to have a character named Masaru, and learned of Masaru Daimon's name after giving her Masaru his name. The fic started in May 2014, and DRAE came out in September of that year.
** This fic has [[spoiler:an Ultimate Assassin who turns out to be one of the good guys]]. In ''VisualNovel/DanganronpaV3KillingHarmony'', it's revealed in the midgame [[spoiler:Maki's true identity is the Ultimate Assassin, and she's one of the good guys]]. Even better yet, [[spoiler:Shuuya nearly kills [[BigBad Saemi]] in revenge for Miyako's HeroicSuicide (and kills her during her execution to prevent her from going out on her own terms). Maki tries to kill Kokichi (the supposed mastermind at the time) after he abducts Kaito, and later offers to kill the real mastermind, Tsumugi.]]

[[folder: ''Web Animation/Death Battle'' ]]

* This [[http://www.deviantart.com/art/Death-Battle-Lion-O-vs-Link-The-Battle-393726460 fanmade]] ''DEATH BATTLE'' has Link use his strength-enhancing gauntlets to use a pillar as a club. Come ''VideoGame/HyruleWarriors'', he now has this as an attack.
* [[http://kermitthefrog223456.deviantart.com/art/Erza-vs-Zoro-Death-Battle-575547566 This]] fan-made battle between [[Anime/OnePiece Roronoa Zoro]] and [[Anime/FairyTail Erza Scarlet]] at the climax has [[SurprisinglyRealisticOutcome Erza summoning 200 swords at once via Heaven's Wheel, at which point it becomes clear that Zoro is way in over his head]]. When Ben and Chad did [[Recap/DeathBattleS03E13ZoroVsErza the actual battle]], it was determined that despite this ability of Erza's she really had nothing in her arsenal that could bring down Zoro's superior speed and destructive capability.

[[/folder]]

[[folder: Franchise/The DCU ]]

* In early 00's fanfiction ''Fanfic/AForceOfFour'', ComicBook/PowerGirl tells her father fitted her ship with a simulation because they didn't know enough about suspended animation... a technology which has played a role in every Kara's [[ComicBook/TheSupergirlFromKrypton2004 canon]] [[ComicBook/LastDaughterOfKrypton origin]] written since.
* ''Fanfic/TheGoldenBoysLastTemptation'': In this 2001 fanfic, a demonic figure tries to tempt Kara Zor-El by showing her several dark timelines, including one universe called New Earth where her cousin died and she never existed. Three years later, DC would publish ''ComicBook/TheSupergirlFromKrypton2004'', introducing Kara to New Earth continuity.
* The ''ComicBook/{{Supergirl}}'' story ''Fanfic/HellsisterTrilogy'' provides several moments of this kind:
** Kara Zor-El and Dev-Em become lovers. Flash-forward several years and Dev-Em is one of her enemies in ''[[ComicBook/NewKrypton the main universe]]'' and ''[[ComicBook/ManOfSteelPrequel the DCEU]]''.
** An alternate universe Saturn Girl is brunette, right like ''Series/Supergirl2015'''s Imra Ardeen.
** Kara having a Legionnaire lover who wants her to move to the 31st century with him, several years before the ''WesternAnimation/JusticeLeague Unlimited'' episode where Kara fell in love with Brainiac 5 and moved to the ''ComicBook/LegionOfSuperHeroes'' future.
** Satan Girl planning to force entire worlds to worship her like a goddess several years before [[ComicBook/Supergirl2005 Supergirl's Sterling Gates' run]] reimagined the character like a death and love alien goddess.
** A Kryptonian doppelganger of a hero of the House of El plus Mordru plus the Legion of Super-Villains come together to destroy the Legion? And the Supergirl of Earth-One gets to do some fighting? It sounds like the plot of ''ComicBook/FinalCrisis'' tie-in ''ComicBook/LegionOfThreeWorlds'', which came out nine years later, isn't it? Compounded by the fact Darkseid was the next BigBad.
** Kara isn't sure what she wants to join the League. A few years later, Supergirl would join the Justice League in the comics.
* ''Fanfic/KaraOfRokyn'' (''ComicBook/{{Supergirl}}''): During a scene, Superman's uncle mutters he'd look stupid in a pair of trunks, years before the "Trunks: Yay or Nay?" arguments among Superman fans.
* In ''Fanfic/SupermanOf2499TheGreatConfrontation'', Supergirl has a descendant called "Katherine", long before [[ComicBook/Supergirl2005 Catherine Grant]] became a personal nemesis in the comics.

[[/folder]]

[[folder: ''Western Animation/The Fairly Odd Parents'' ]]

* In ''Fanfic/NeverHadAFriendLikeMe'', the idea of [[Literature/TheLordOfTheRings using a volcano as a way to destroy magical objects]] and [[spoiler:Timmy almost dying by an anti-fairy dropping him into lava]] both showed up in this story a few months before the premiere of ''Film/AFairlyOddSummer''...

[[/folder]]

[[folder: ''Video Game/Fate Grand Order'' ]]

* Chapter 4 of ''[[https://www.fanfiction.net/s/13786415/4/Chaldea-Selects Chaldea Secrets]]'' has Ritsuka "defeating" [[GenderFlip a female Kirschtaria Wodime]] by revealing that he is a mediocre mage, knowing her pride will make her teach him to be a better mage and eventually get her to fall in love with him. The Olympus Chapter of the game reveals [[spoiler:that not only was Kirschtaria GoodAllAlong (albeit an AntiVillain variant) but that his plan involved elevating humans, including [[WorthyOpponent the protagonist]], into gods]], which paralleled female Wodime's action in the fanfic.

[[/folder]]

[[folder: ''Franchise/Final Fantasy'' ]]

* A ''VideoGame/FinalFantasyXIII'' post-game fanfic written in June 2010 called [[http://www.fanfiction.net/s/6045426/1/ New Dawn]] has Lightning, feeling empty and unfulfilled though happy her friends and family are doing well, go off on her own as if beckoned to go on another journey. Late that year, the [[http://dilly-shilly.blogspot.com/ Episode One novellas]] were released and the next month after, ''VideoGame/FinalFantasyXIII2'' is announced. What do they portray? Lightning, feeling empty and unfulfilled though happy her friends and family are doing well, go off on her own as if beckoned to go on another journey.

[[/folder]]

[[folder: ''Franchise/Fire Emblem'' ]]

* A common FandomSpecificPlot in ''VideoGame/FireEmblemThreeHouses'' is to have Dimitri and Claude, whose nations bear no ill will toward each other, join forces to put a stop to Edelgard's empire, who attacks both nations in the war that makes up the second half of the game. While such a team-up never comes to pass in ''Three Houses'' due to the lords all dealing with their own personal issues, ''VideoGame/FireEmblemWarriorsThreeHopes'' ''does'' feature two of the three leaders joining forces: [[spoiler:Claude and ''Edelgard'', who put aside their hostilities after learning they both have grievances with the Church of Seiros, whose army has integrated itself into Dimitri's kingdom due to Faerghus' long-standing support of the church]].

[[folder: Fusion Fic ]]

* In 2011, someone made [[https://www.youtube.com/watch?v=XZI2TZVWOxM a video of]] the Genie from ''WesternAnimation/{{Aladdin}}'' "singing" the theme for ''Series/TheFreshPrinceOfBelAir''. All the comments note how the editor somehow predicted Creator/WillSmith as the Genie in the [[Film/Aladdin2019 live action remake]].
* [[http://dennisculver.deviantart.com/art/Nicktoon-Avengers-304287918 This fanart]] from 2012 depicting the 1990s Franchise/{{Nicktoons}} characters as [[Film/TheAvengers2012 the Avengers]] becomes this after it was announced that there will be an ''Avengers''-esque crossover film with the classic Nick characters.
* [[https://www.deviantart.com/prettyoddchild/art/fairly-odd-deathnote-305537046 This]] fanart made in 2012 featuring [[WesternAnimation/TheFairlyOddParents Timmy Turner]] dressed as [[Manga/DeathNote Light Yagami]] becomes hilarious after the [[Film/DeathNote2017 2017 American film adaptation of Death Note]] [[AdaptationNameChange changes Light's surname from Yagami to Turner]]. Most of the comments in the comment section are about how this fanart predicted the future.
* ''[[https://www.fanfiction.net/s/9990992/1/Tears-of-Revelry Tears of Revelry]]'' (''WesternAnimation/AvatarTheLastAirbender'' & ''Anime/MobileSuitGundamWing'') was (by the author's admission towards the bottom) written prior to ''WesternAnimation/TheLegendOfKorra'' airing, and was first posted some months prior to Season 3. The prologue narrative briefly mentions that the Air Nomads "had regrown in strength" over a period of 150 years post-A:TLA, but not how. Then [=LoK=] Season 3 hit and it turns out that Harmonic Convergence caused a number of non-benders to become Airbenders...

[[folder: ''Series/Game Of Thrones'' / ''Literature/A Song Of Ice And Fire'' ]]

* ''Fanfic/TheRavensPlan'':
** Sansa's friendly attitude towards Dany comes off as this considering the tension between the two in Season 8.
** That [[spoiler: a PeggySue was needed to stop the Long Night in this fic]] is this after [[spoiler: Arya single-handedly averting the Long Night by killing the Night King]] in canon. [[FridgeLogic Maybe the fact that]] [[spoiler: Arya]] died fighting Euron in the backstory of the fic had something to do with the difference in outcomes between canon and the fic?
** Repeatedly throughout the story, people react with disgust to finding out that Jon and Dany are in a relationship despite being related, until others point out that they're Targaryens, so that makes it okay. When this big InternalReveal comes about in canon, no one other than Varys even acknowledges the incest aspect, and it's quickly brushed off when he brings it up.
** Jon accepting the throne considering his adamant refusal in the show.
** There is something darkly amusing about Jaime's angst over killing Cersei considering he died with his arms wrapped lovingly around her in the show.
** Also amusing is that, in ''The Raven's Plan'', Jaime killed the Mountain before killing Cersei, and the Hound went down fighting Euron, whereas in the show, [[spoiler: it was Jaime who was killed by Euron and the Hound who killed the Mountain]].
** Bran's adamant acknowledgement that Jon is their King considering [[spoiler: in the end of the TV series, he became the King of Westeros]].
** Edmure Tully is presented as having [[TookALevelInBadass become much more dangerous and embittered]] after everything he went through. His final appearance in canon shows that even after everything, he's still as much an idiot and wimp as he ever was.
** Yara and Theon's reunion sees her welcoming him back warmly, then kicking him in the balls to remind him what he's regained. In canon, their reunion when he rescues her from Euron involves her headbutting him before embracing him.
* ''Fanfic/TheKingNobodyWanted'' and ''Fanfic/LetTheGalaxyBurn'' both have Targaryens or their allies having visions of the White Walkers invasion. The pilot of ''Series/HouseOfTheDragon'' says that Aegon the Conqueror himself had such a vision and suggests it motivated many of his actions and those of his descendants.

** From Episode 2, Chibodee Crocket, voiced by Creator/Takahata101 using a Southern accent, tells a rambling story starting with the phrase "I ever tell you that story 'bout my best friend?" Later, Taka would play Ellis in Team Four Star's ''VideoGame/Left4Dead2'' LetsPlay.
** In Episode 4, Taka voices the commissioner using the same voice he would later use for Dartz on ''WebVideo/YuGiOhTheAbridgedSeries''.

[[folder: ''Literature/Harry Potter'' ]]

* Released in 1999, ''[[https://www.fanfiction.net/r/3674/ Love Is]]'' proposed the notion that Snape loved Lily, even mentioning that the Mauraders almost turned him into a werewolf. Come Book 7, and it reveals that Snape loved Lily.
* Tara Gilesbie, author of ''FanFic/MyImmortal'', predicted in an author's note before ''[[Literature/HarryPotterAndTheDeathlyHallows Deathly Hallows]]'' came out that [[spoiler:Harry would have to let himself die in order to defeat Voldemort, because he himself is a Horcrux.]] Fast forward to when the book came out, and ''she was right!'' A lot of people had the same idea, to be fair, but the fact that ''Tara'' of all people figured it out is hilarious.

[[/folder]]

[[folder: ''Series/House'' ]]

* In ''I Am Not The Walrus'', Chase inadvertently admits furries make him nervous, which House finds hilarious, sarcastically asking him if he was "ravaged by a herd of My Little Ponies". This was written before ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' existed.

[[/folder]]

[[folder: ''Western Animation/Invader Zim'' ]]

* ''Fanfic/TheNewAdventuresOfInvaderZim'' has a couple of examples:
** The first chapter, written prior to the release of the first issue of the ''WesternAnimation/InvaderZim'' [[ComicBook/InvaderZimOni continuation comic]], features Dib almost getting into a dogfight with Zim with Tak's ship, only to realize that he doesn't know how to operate the ship's weapons, leading to Zim [[CurbStompBattle curb-stomping him]]. In Issue 2 of the comic, Dib is facing down Zim in a spaceship dogfight, and realizes he doesn't know how to use the weapons... and [[TooDumbToLive Zim tells him how]], leading to ''Zim'' being curb-stomped.
** Episode 4 of Season 1 has, as one of MIMI's hallucinations, a ShoutOut to ''Film/TheShining'' in the form of a pair of meat children asking her to come play with them forever. This was published in 2015; flash-forward to 2017, and the comic series has a similar joke, wherein Dib ([[FreakyFridayFlip in GIR's body]]) imagines a bunch of copies of GIR asking him to come play forever.
** Senior is a CommunicationsOfficer on the ''Massive'' who has no problem talking back to the Tallest rather than deferring completely to their orders. Then along comes [[WesternAnimation/InvaderZimEnterTheFlorpus the movie]], which features the otherwise unnamed Comms Officer, who keeps trying to call out the Tallest on their TooDumbToLive actions regarding the Florpus.
** Episode 4 of Season 1 is loosely based on the unproduced episode "GIR's Big Day", which would later go on to be adapted as the first issue in the quarterly format that the comic series switched to in 2020.

[[folder: ''Franchise/Kingdom Hearts'' ]]

* The fanfic ''[[http://www.fanfiction.net/s/4291045/1/ Harvey Birdman versus Organization XIII]]'' has [[WesternAnimation/HarveyBirdmanAttorneyAtLaw Harvey]] going to The Castle That Never Was to arrest [[VideoGame/KingdomHeartsII Xemnas]], alleging that his ethereal blades were violating copyright from ''Franchise/StarWars'' and [[EpicFail fails horribly]] to enforce it. Then, in 2012, Disney buys Lucasfilm.
* ''Fanfic/TheOldLifeAliveAgain'':
** Marluxia's GreenEyedMonster attitude towards Axel makes more sense with ''[[VideoGame/KingdomHeartsX Kingdom Hearts Union X]]'' revealing that Marluxia and Larxene's Somebodies knew each other in the past.
** Here, Xigbar somehow managed to manipulate Xemnas into thinking Roxas and Xion's love was getting in the way of the Organization's goal. Come Kingdom Hearts 3, and it's revealed Xigbar was manipulating Xehanort all along.
** In a side comic in which Roxas repeatedly asks Xemnas to change Organization XIII's name to Organization XIV (mostly because he was feeling that Xion, being Number XIV, was left out), Ansem's Guardian attacks Xemnas. His motive is revealed in Kingdom Hearts 3: being Terra's heart, he was most likely seeing Roxas as Ventus, and figured out Xion as Roxas's motive behind annoying Xemnas with this question, since Roxas was feeling Xion was left out. Knowing Terra's BigBrotherInstinct towards Ventus, Guardian most likely wanted Roxas to be happy.

[[folder: ''Franchise/Kung Fu Panda'' ]]

* ''Fanfic/ADifferentLesson'' happens to contain numerous plot points that come across as funny compared to plot points in later stages in the franchise.
** When Tai Lung is attempting to 'lighten the mood' on the way to Chorh-Gom by helping Tigress and Shifu reconcile, Tigress has this to say: "And since when have you become an expert on entertainment and leisure? Did you take up clowning when I wasn't looking?" No...but [[WesternAnimation/KungFuPandaLegendsOfAwesomeness at one point in the series]], [[http://images1.wikia.nocookie.net/__cb20110909082428/kungfupanda/images/0/02/Kungfupandamrclowntriestocheeruptigress.png Ping practices clowning]]. (And now that that image is in your head, just try and keep from imagining Tai Lung doing and saying all the things the goose did when Tigress was sick.)
** In Chapter 38, Tai Lung's thoughts: "No one needed to know he'd been so caught up in romancing Tigress he might not have noticed if Po had started dressing up in a ''cheongsam''. ''Oh gods...why did I have to go there? Someone kill me now, please...or at least murder my imagination.''" Well, it may not be a ''cheongsam'', but we have gotten to see Po dressed as a woman in "[[WesternAnimation/KungFuPandaLegendsOfAwesomeness Ladies of the Shade]]". And Tai Lung's reaction is pretty appropriate.
** On a related note, Song herself being a violet-eyed snow leopardess who is nominally on the side of the bad guys, performs a HeelFaceTurn to help fight her former allies, and has a ShipTease with Po sounds a lot like Jia.
** Monkey getting put under MindControl (with RedEyesTakeWarning), something which was utterly PlayedForDrama (and horror) in the fic, becomes a lot funnier after seeing "The Scorpion's Sting".
** The BigBad is a dark master of chi who used to be allied with Master Oogway, but was eventually corrupted by his lust for power, leading Oogway to seal him away until he finally made his return centuries later, after Oogway's death. Are we talking about Heian Chao or [[WesternAnimation/KungFuPanda3 Kai]]?
** The third movie also has a moment where a panda dons Master Flying Rhino's armor (and which Po himself admitted to fantasizing about), and the statues of the Vault of Heroes appearing uncovered and open on the mountain around the stairs... And considering both Heian Chao and Kai are spirits, it's surely the case that Chao was also [[spoiler:immune to the Wuxi Finger Hold]], which makes Tai Lung warning Po not to use it incredibly prescient. [[FridgeHorror It's a good thing the possibilities he suggested never happened with Kai, isn't it?]]
--->'''Tai Lung''': Just what d'you suppose would happen if you used the ultimate ''chi'' move on the ultimate master of ''chi''? The least that would happen is it blowing up in your face and doing absolutely nothing. Worse, you might just make him stronger...or allow him to turn it back on you, corrupt you, vaporize you...
** Another more minor point of amusement: in the author's about me page, he notes that the voice he had in mind for Bao (Po's father in this fanfiction) was Bryan Cranston. Out comes ''WesternAnimation/KungFuPanda3'', and guess who Po's canon father is voiced by?

[[folder: ''Franchise/The Legend Of Zelda'' ]]

* The fangame ''VideoGame/TheLegendOfZeldaTheMissingLink'' featured a brand new item called the Magic Hourglass that allowed Link to rewind his location to where he was standing while the rest of time flowed normally to solve puzzles. Three years later, ''VideoGame/TheLegendOfZeldaTearsOfTheKingdom'' would have a very similar ability in the form of Recall, just with objects instead of Link.

[[folder: ''Western Animation/The Loud House'' ]]

* A fancomic for ''WesternAnimation/TheLoudHouse'' featured the Loud siblings, over the course of the comic, cosplaying as various different Nickelodeon cartoon stars (Lincoln as several male leads and Leni as [[WesternAnimation/SpongebobSquarepants Patrick Star]] for example) but the one that's this trope is Luna. Her cosplay is being stylized to look like [[WesternAnimation/DannyPhantom Sam Manson]], who turns out to share the name [[spoiler: and gender]] of Luna's ultimate crush.

[[folder: ''Manga/Lucky Star'' ]]

* A fan-meme involves "Kurokona", a pale, black haired version of Konata who plays her character [[SurprisinglyRealisticOutcome more realistically]] than her canonical OtakuSurrogate version.

[[folder: ''Franchise/Marvel Cinematic Universe'' ]]

* ''[[https://archiveofourown.org/works/881056/chapters/1695818 The Battle for New York: Take 2]]'' features numerous real-life actors getting cast in various roles in a pair of InUniverse films based around the events of ''Film/TheAvengers2012''. The story was first published in 2013; as of 2022, several of these actors -- specifically Benedict Cumberbatch (Dr. Strange), Karen Gillan (Nebula), Michael Keaton (the Vulture), Forest Whitaker (Zuri), and Christian Bale (Gorr the God-Butcher) -- have joined the MCU proper.
** Additionally, Fincher's choice of actor to play Captain America is Jensen Ackles, who would end up playing an {{Expy}} of him in ''Series/TheBoys2019''.
* ''[[https://archiveofourown.org/works/37186546/ Tingle]]'':
** Peter Parker, Yelena Belova and Kate Bishop face the Spot in their first team-up almost a year before trailers for ''WesternAnimation/SpiderManAcrossTheSpiderVerse'' revealed that the Spot would be the villain in that film.
** The final chapter has Peter mention how he fought a man in a frog suit, months before the MCU Leap-Frog would ‘officially’ debut in the ''Series/SheHulkAttorneyAtLaw'' ep “[[Recap/SheHulkAttorneyAtLawS1E8RibbitAndRipIt Ribbit and Rip It]]”

[[folder: Franchise/Marvel Comics ]]

* ''[[Fanfic/UltimateSleepwalker Ultimate Sleepwalker: The New Dreams]]'' had multiple {{Take That}}s aimed at Creator/JohnKricfalusi, with one character in particular condemning him as a pretentious hack who constantly insults other animators' work while his own work is utter garbage. As of 2019, this view of Kricfalusi became widespread in real life, particularly after the universally-loathed ''WesternAnimation/CansWithoutLabels'' was finally released six years after its due date.
* In ''Fanfic/XMen1970'', ComicBook/JeanGrey leaves the Xavier's Mansion and looks for a teacher job. In the comics, the Xavier's Mansion became a real school one year later.
* ''Fanfic/XMenTheEarlyYears'': The next paragraph was written over one decade before Jean Grey encouraged Iceman to come out.
-->Bobby Drake was currently in the library, too, thinking and plotting. He owed Hank, and it was going to be the prank of a lifetime. He'd just finished a session with Professor Xavier, who'd explained that the reoccurring dream that Bobby had been having was "a classic fear of abandonment," and not what Hank had told him it symbolized. Now that he actually thought about it, how many ways could you interpret a dream of getting launched into space alone? Hank had told him it symbolized his wanting to explore new frontiers, and the rocket ship had represented a certain part of the male anatomy. He'd then suggested that maybe Bobby should go talk to Jean, because she could introduce him to some nice guys, and then his dream would go away.

[[folder: Western Animation/Miraculous Ladybug ]]

* Many ''Miraculous Ladybug'' fics where someone else wields the Butterfly Miraculous, such as [[spoiler:Nathalie Sancouer]] in ''Fanfic/CrimsonAndNoire'' or Nathaniel Kurtzberg in ''Fanfic/MiraculousTalesOfScarletBeetleAndIkatiBlack'', go by the name Monarch, base on the Monarch Butterfly. Season 5 would have Hawkmoth changing his villain name to Monarch [[spoiler:after acquiring ''all'' the Miraculouses save for the Ladybug and Black Cat]].
* The fanfic ''[[https://archiveofourown.org/works/37853032/chapters/94520563 A Gift of Worms]]'' has Cat Noir fusing the Cat and Rabbit Miraculous and becoming a hero named Rabbit Noir. During the very first episode of Season 5, Adrien does indeed fuse the two Miraculous and become Rabbit Noir. Mind that the episode aired two months later the fic ended.
* ''Fanfic/HeroChat'' has it hinted that Luka is Jagged Stone's illegitimate child and eventually confirmed in the story's version of "Truth" when Jagged finds out that Luka is his son and Anarka hid it from them. [[spoiler:A later season 4 episode reveals that both Luka and his twin-sister Juleka are Jagged's children]].

[[folder: Western Animation/My Little Pony Friendship Is Magic ]]

* ''Fanfic/TheDearSweetieBelleContinuity'': "Cutie Mark Crusaders Dream Warriors" has Princess Luna help the CMC fight back against their nightmares. As of season 5, all three of them [[Recap/MyLittlePonyFriendshipIsMagicS3E6SleeplessInPonyville have received aid]] [[Recap/MyLittlePonyFriendshipIsMagicS4E20ForWhomTheSweetieBelleToils from the night princess]] [[Recap/MyLittlePonyFriendshipIsMagicS5E4BloomAndGloom within their dreams]].
* Creator/DakariKingMykan always wanted to make a more action-oriented story than ''[[WesternAnimation/MyLittlePonyFriendshipIsMagic Friendship Is Magic]]'', and thus wrote ''Fanfic/MyBravePonyStarfleetMagic''. Come [[Recap/MyLittlePonyFriendshipIsMagicS4E26TwilightsKingdomPart2 the season 4 finale]], suddenly the show he hates actually gets an amazing action sequence that blows any he could make out of the water.
* ''Fanfic/UnderTheNorthernLights'': In chapter 30, after seeing through Twilight's evil sorceress charade and realizing that she has a good heart beneath it, Princess Ljufa concludes that Twilight is a villain who, deep down, wants to be good, and decides to convince her to that she doesn't have to be a villain and is actually a good person who deserves to love herself. Twilight finds this absolutely mortifying, since it's pretty obvious that Ljufa cast them as the heroine and villainess of, well, a kids' cartoon, and is ''especially'' mortified when Ljufa and her handmaidens pull out instruments and start singing. The humorous part is that this story is old enough to entirely predate the show proper's long track of redeeming villains and assorted antagonists; the only redemption in the show up to that point had been done with a magical rainbow laser, with no speeches or song involved. The scene is quite humorous on its own, but it becomes hilarious in light of how often the main characters ended up following in Ljufa's shoes in time, and how often Twilight herself ended up engaging in the same behaviors that her version in this story found cheesy and embarassing.
-->''This is... this is the "reform the villain speech"! The one that you always give to the mean pony in stories! Like... well, like in a cartoon for... for little fillies! She is trying to reform me!''
* ''[[http://www.fimfiction.net/story/71487/fallout-equestria-snowfall Fallout: Equestria: Snowfall]]'' introduces crystal pony unicorns. Crystal pony unicorns appear in ''ComicBook/MyLittlePonyFiendshipIsMagic #1''.
* ''Fanfic/DiscordsNewBusiness'': Chapter 13, published in June 2017, revolves around the Cutie Mark Crusaders being aged up and going to Manehattan. A little over two years later, the exact same basic plot -- the Crusaders being aged up and going to another town -- happened in canon's [[Recap/MyLittlePonyFriendshipIsMagicS9E22GrowingUpIsHardToDo season 9]].

[[folder: ''Manga/Naruto'' ]]

* [[Fanfic/ShirukaYo The first]] completed ''Manga/{{Naruto}}'' fic on FF.net was a [[SlashFic Naruto/Sasuke]] fic (in fact, many early fics were). It ends with an author note that says "More ''Naruto'' fics, I think, are needed". Within six years ''Naruto'' would be one of the biggest manga fandoms and is only behind ''Literature/HarryPotter'' as the fandom with the most fanfics on the site.
* ''Fanfic/SonOfTheSannin'' has two of these in relation to the ''[[Anime/BorutoNarutoNextGenerations Boruto]]'' anime:
** Naruto and his friends learn to tree-walk and water-walk in the Academy, since the author thought it was a very useful skill, yet basic and easy enough to be taught in the Academy. Later, a ''Boruto'' episode that this is also the case in the Academy of the new era.
** The Chunin Exam Finals has an even bigger example: Naruto, Sasuke and Gaara make it to the final round and are about to have a three-way fight, but Rasa protests and claims that the two Konoha Genin are going to double team his son. In the ''Boruto'' adaptation of the movie's Chunin Exams, Boruto (Naruto's son), Sarada (Sasuke's daughter) and Shinki (Gaara's adoptive son) make it to the final round, where they fight in a three-way match, and Boruto and Sarada, the Konoha Genin, end up double teaming Shinki, the Suna Genin.

* ''Fanfic/TheChildOfLove'': The title of chapter 8 is "You Are Not Alone". Keep in mind that chapter was published at least seven years before the first ''Anime/RebuildOfEvangelion'' movie was a thing.
* ''Fanfic/{{HERZ}}'': In chapter 4, Asuka calls her daughter Akiko "Aki-chan". Several years later, when Jimmy Wolk wrote ''Fanfic/TheSecondTry'', [[spoiler:he named Shinji and Asuka's daughter "Aki-chan".]]

[[folder: ''Series/Odd Squad'' ]]

* The BigBad of ''Fanfic/AllMixedUp'', who owns an aquarium as a FamilyBusiness, used to be employed with Odd Squad and had the name Ocean when she was an agent. A year after the fanfic was completed, an Odd Squad agent with the same name would appear in Season 2 as a side character, working in the newly-established Creature Care department and being a FriendToAllLivingThings, but being firmly on the heroes' side and not displaying any villainous tendencies.
* "Slipping into mathness", which is a more eloquent and odd term for SanitySlippage in the ''Odd Squad'' universe, was called in ''[[Fanfic/PatternsOfThePast Patterns of the Past]]'' long before it was revealed to be a thing in [[Recap/OddSquadS2E7OlympiasDayOtissDay "Olympia's Day"]]. In Chapter 6, Old Missie explains to Olesya that "Mathness" is when an agent taps into the hidden world of math using only their brain, eliminating the need to go to the Mathroom. Doing so, however, comes at a cost in the form of them being completely consumed by it to the point where they suffer from a loss of sanity. Unlike with Olympia, who was pulled out of her sanity slippage by Dr. O fairly quickly and took a long while to fully slip into mathness, Old Missie explains that some of her agents have gone so far off the deep end that it took Odd Squad Doctors an incredibly long time to pull them out and restore their sanities, and it can only take the tiniest exposure to mathematics for an agent to start losing it.

* ''Fanfic/CobysChoice'':
** During the Little Garden arc, Coby finds and eats a Devil Fruit that lets him turn into a Triceratops. In chapter 998 of the manga, Sasaki, a member of the Beast Pirates Flying Six, is revealed to have eaten the Dragon-Dragon Fruit: Model Triceratops. As there is only one of any particular Devil Fruit power (whether as a fruit or already eaten) in existence at a time, it has some interesting implications in how the author will handle it.
** At the end of the Syrup Village arc, Kaya gives Usopp a good luck kiss before he joins the Straw Hats on their journey. [[Series/OnePiece2023 The 2023 live-action series]] would also have Kaya giving Usopp a BigDamnKiss.

[[folder: ''Western Animation/The Owl House'' ]]

* The main premise of ''Fanfic/TheForbiddenDrink'' is a divergence from "[[Recap/TheOwlHouseS3E1ThanksToThem Thanks to Them]]" wherein Luz drinks the vial of Titan's Blood to keep Belos from getting it, causing her to transform into a half-Titan hybrid. A month after the story was first published, the series finale "[[Recap/TheOwlHouseS3E3WatchingAndDreaming Watching and Dreaming]]" aired, and a main plot point of the episode is Luz being transformed into a half-Titan by the Titan's spirit in order to defeat Belos in the FinalBattle.

* The ''WesternAnimation/MonstersInc'' fanfiction series ''Fanfic/AngelasPetMonster'' was published two years before ''WesternAnimation/MonstersUniversity''. And yet, there's some interesting foreshadowing, including, but not limited to...
** Randall turning a heart pattern.
** Randall being nicknamed "Randy".
** Mike making an offhand reference that scaring was his "past life's dream".

[[folder: ''Franchise/Pokemon'' ]]

* ''Fanfic/TheEditWarForAshsFreedomToNotBeBetrayed'':
** Arceus briefly ponders introducing an Alolan form for Golem. About a week after the fic's publication, Alolan Golem was revealed.
** Darkern repeatedly tries to give Ash a Riolu; despite Arceus blocking his initial attempts to do so, Ash ''does'' end up with a Riolu during his first six months on the island. Four years after the fanfic was written, Ash really did get a Riolu in ''Anime/PokemonJourneysTheSeries.''
** At one point, Darkern claims that all of Ash's adventures end in failure; later, he trashes Alola as a "gym-less reject of a region" and refuses to send Ash there for that reason. [[spoiler:Not only did Ash win his first official Pokémon League in Alola, the following series saw Ash facing off against other regional champions and winning.]]
** Darkern constantly tries to get Ash to catch a Legendary, only to fail because Arceus stops him (read: Cross hates the idea of Ash having Legendaries, period). In Alola, Ash catches a Meltan that befriended his Rowlet after Rowlet defended Meltan from Team Rocket, and that Meltan later evolves into Melmetal, who is a Mythical Pokémon, much like Arceus. (Mythical Pokémon are the one class above Legendary Pokémon.)
** Darkern dismisses Farfetch’d and is opposed to Ash having one on his team. ''VideoGame/PokemonSwordAndShield'' introduced a pure Fighting-type regional variant of Farfetch'd with an evolution in Sirfetch’d, boosting its appeal and usefulness... and Ash caught a Galarian Farfetch'd for real in ''Anime/PokemonJourneysTheSeries''.
** One of the hipsters that challenges Ash early in the fic has a Gengar. Ash would catch a Gengar himself in ''Anime/PokemonJourneysTheSeries''.
* ''Fanfic/PokeWars'' has plenty of cases where Pokémon fight alongside armed humans and in at least one case, use firearms. Now look at what ''VideoGame/{{Palworld}}'' has to offer.
* ''Fanfic/TooManyAshes'' was published prior to the publication of any promotional material for ''Anime/PokemonTheSeriesSunAndMoon'', resulting in the author guessing what Pokemon Ash would be most likely to have on his Alola team or would work as counterparts to the former. Despite this, the Ash clone representing the Alola main team (Ash 13) shares his Rowlet starter with the canon version of Ash, while the clone with the counterpart Alola team (Ash 14) has a Litten akin to the one Ash actually caught. Additionally, the other Pokemon on Ash 14's team (Popplio, Bounsweet, Charjabug, and Alolan Vulpix), along with Ash 13's Alolan Marowak, are all species his friends at the Pokemon School own.

[[folder: ''Anime/Pretty Cure'' ]]

* ''Fanfic/PrettyCurePerfumePreppy'':
** In episode 32, a Spanish Pretty Cure explains that there are other Pretty Cure teams around the world. A few years later, [[Anime/HappinessChargePrettyCure that would become canon.]]
** ''Perfume Preppy's'' main character is named Chloe. When ''Anime/SmilePrettyCure'' was dubbed as ''Glitter Force'' in 2015, one of the dub names revealed was Chloe (but the Chloe in question is Reika/Cure Beauty).

[[/folder]]

[[folder: ''Web Animation/RWBY'' ]]

* ''Fanfic/WeissReacts'': The fic featured the HumongousMecha [[Anime/TengenToppaGurrenLagann Gurren Lagann]] as a regular plot element, had Jaune crossdressing for a [[VisualNovel/FateStayNight Saber cosplay]] and Cinder joining the school as a teacher. [[spoiler: Months later, the [[HumongousMecha Atlesian Paladin]] is unveiled as a regular plot element of Volume 2, Jaune ends up crossdressing to cheer Pyrrha up, and Cinder ends up in Beacon as a student.]]
** Similarly, plushies of Weiss are a RunningGag- and one EnsembleDarkhorse, Vivi, is an animated Weiss plushie. Now that Rooster Teeth have actually started ''selling'' Weiss plushies....
* ''Fanfic/{{White Sheep|RWBY}}'': The stoic and esteemed General Ironwood being unable to bring even himself to ask his kingdom's naive teenage girl android about her diary's... mistakenly ''salacious''-sounding account of what she and her new friends did while she was unsupervised among the populace of Vale is already pretty damn funny. But the idea that Ironwood was so disturbed that he couldn't bring himself to talk to Penny gains an ''extra'' layer of hilarity when one factors in ''RWBY'' canon's later confirmation that Ironwood can enforce inhuman stoicness on himself as a Semblance, and assume that Ironwood couldn't bring himself to talk to Penny ''even with that''.

[[/folder]]

[[folder: ''Western Animation/She Ra And The Princesses Of Power'' ]]

* ''Fanfic/CatRa'': Each season was written without the author having seen any further ahead, leading to some big misjudgements about where the show was going...or being quite prescient.
** Catra ApologizesALot whenever she talks to Adora, when her HeelFaceTurn on the show ended up being doing so for the first time in her life, to anyone.
** Spinarella and Netossa are repeatedly described as "friends."
** The physical effects of Adora's shadow powers are uncannily like Horde Prime's possession.
** While acting like a cat from the First Ones' virus, Catra licks Glimmer's face. Later in the actual show, she licked Glimmer's arm.
** In "Reunion" Bow's story about the academy has the extra complication of Catra supposedly being his girlfriend, to which Glimmer is quite put out that she couldn't have played the role. Catra even gives a further embellishment that Glimmer had a crush on him too.
** Monokub himself points out that the false reality at the end of Season 3 bears quite a resemblance to his version of what happens in Catra's mind when she's infected with the First Ones' virus: waking up with no initial memory but quickly thinking the new reality is real, things disappearing with no one else noticing, and finally having to run from a destructive white force obliterating all in its path.

[[folder: ''Franchise/Star Trek'' ]]

* The first line of the [[http://www.fanhistory.com/wiki/A_Fragment_Out_Of_Time first published]] [[Series/StarTrekTheOriginalSeries Kirk/Spock]] fic is "Shut up. We're by no means setting a precedent." Of course, K/S went on to spawn SlashFic as a genre, setting quite possibly the most important precedent in the history of fandom.
* In Letter 55 of [=Zelda12343=]'s ''[[https://www.fanfiction.net/s/7742541/55/Dear-Fanfiction-Writers-TOS-style Dear Fanfiction Writers TOS Style!]]'', [[Series/StarTrekTheOriginalSeries Khan]] speaks out against the Kirk/Khan pairing, even though the author herself acknowledges she'd never seen this pairing on [[Website/FanFictionDotNet FFN]]. After ''Film/StarTrekIntoDarkness'' came out, Kirk/Khan became a popular pairing over at the ''Film/StarTrek2009'' on FFN.

* ''Fanfic/AllInTheFamily'' has a character named Acacia Castro-Avila whose FamousAncestor is supposedly UsefulNotes/FidelCastro himself. This is HilariousInHindsight when you realize that a year after the fanfic was published, Fidel Castro was revealed to have had [[ReallyGetsAround many lovers]].

[[folder: ''Video Game/Super Mario World'' ROM hacks ]]


Oftentimes, ROM hacks will predict mechanics and other stuff in official Mario games. For more specific examples:
* In ''VideoGame/BrutalMario'', the final world is Peach's Castle transformed into a hellish lavascape. ''VideoGame/NewSuperMarioBrosU'' not only features such a final world, but also uses the same Koopaling order as this hack.
* ''VideoGame/VanillaLevelDesignContest'' had a mechanic where you can't take Yoshis or powerups with you into other levels. ''VideoGame/SuperMarioMaker'' would do exactly that.
* In 2015, a Bubble Flower powerup appeared [[https://www.smwcentral.net/?p=viewthread&t=79053&page=1 on SMW Central]], being used in hacks like ''The 12 Magic Orbs'' and ''VideoGame/GrandPooWorld3''. Come 2023, and one of the major new powerups in ''VideoGame/SuperMarioBrosWonder'' is a Bubble Flower that [[https://www.youtube.com/watch?v=Eg6wJbrcYEs looks exactly like the one in SMW]].

[[folder: ''Franchise/Super Sentai/Franchise/Power Rangers'' ]]

* In ''Fanfic/SuperSentaiVsPowerRangersTheLiveblog'', part of the reason why [[{{Tropers/Arcadiarika}} the writer]] chose Sean in the first act of the arc was that she wanted to have him take part in a ''Gokaiger''-related arc, especially when [[Series/PowerRangersSamurai Alex]] and [[Series/PowerRangersJungleFury Jason]] would have their own episodes in ''[[Series/PowerRangersMegaforce Power Rangers Super Megaforce]]'' later on. About a week after covering ''Kaizoku Sentai Gokaiger vs. Power Rangers Samurai'', [[http://www.rangercrew.com/forum/showthread.php?26517-Power-Rangers-Super-Megaforce-Pre-Discussion&p=1099419&viewfull=1#post1099419 there was an announcement]] that confirmed Sean's appearance in the final episode of ''Super Megaforce''.
* Speaking of ''Super Sentai VS Power Rangers'':
** A case of RougeAnglesOfSatin occurs when [[Series/EngineSentaiGoonger Miu Sutou]]'s name is misspelled as ''Mio''. [[Series/ResshaSentaiToqger Not too long]] after the chapter where the error is written is published, the Sentai at the time does have a character named Mio [[spoiler: Natsume]].
*** Compounding the Toqger reference, there was a case of a "Samurai Girl" within the story, written long before Kagura willed the imagination of it to life.
** ''Series/ShurikenSentaiNinninger'''s cameo of Yoshi Sudarso literally proves the fanfic dead wrong in that the Power Rangers cast can't really be forced to speak Japanese when in the ''Super Sentai'' universe. In his appearance, he speaks clear English, making it a point that this universe isn't a FisherKingdom.
** The USSPRA uses a selection system that decides who gets sent to the timeline. Not too long after this crossover was published, ''Series/UchuSentaiKyuranger'' would be an official Sentai show who would use such a system.
** There's ''definitely'' no coincidence that Toei must've picked up this fanfic's plot (time-travelling to past seasons and meeting with their heroes while dealing with a threat from the future)...and applied it to its [[Franchise/KamenRider sister]] [[Series/KamenRiderZIO franchise]]. In fact, had he wrote this during the time that series was airing, he would've cited that as well.
** The [[CrackPairing crack pairings]] are virtually an infamous thing about the fanfic. especially considering its crossover setting. It wouldn't take a bit longer for the popularity of [[Series/MightyMorphinPowerRangers Jason]]/[[Series/PowerRangersSamurai Lauren]] to rise thanks to ''Shattered Grid'', and that displayed arguably better chemistry. The fact that one of them is from a series Akizuki despises is a bit of an insult to injury as well.
** A prominent Red Ranger consistently taking the spotlight at the expense of others in this story? Sounds like a common criticism for modern Sentai shows, and this was written before that criticism became widespread amongst the fandom. So much in fact, one could say this fic was ahead of its time.
** Werezilla rages out in his reading of Chapter 32, demanding that the fanfiction readers "want this fanfiction to burn in hell". The fic got deleted by the author because he believed that it should be "burnt and ripped". Almost verbatim to what he said.
** In Cole's debut chapter, he was said to have people "treat him like a deity". Many years later, and we get another ranger that wouldn't seem to be treated similarly given the [[Series/AvataroSentaiDonbrothers hordes of people he arrives with carrying him on a pedestal]].
** Flurious' treatment of being a house slave becomes a bit interesting in retrospect when ''Zenkaiger'' comes along and gives us Vroon, who is introduced as a janitor on the receiving end of punishment from Boccowaus. Eerily similar is how Flurious comes from ''Operation Overdrive'', adapted from ''Boukenger'' to which Vroon is based on.
* On 23 July 2010, a ''Franchise/PowerRangers'' fanfic called "[[http://www.rangercrew.com/forum/showthread.php?16268-Mythic-Rangers Mythic Rangers]]" was started, with one character named Hector. On 5 August, the names of the cast for the new 18th season of the franchise were leaked... the new green ranger is played by ''Hector'' David Jr. While the fanfic contains some deliberate Power Ranger references, this one was not intended.
* In 2006, a VideoGame/{{Tekken}} story based off the ''Franchise/SuperSentai'' franchise, [[http://www.fanfiction.net/s/3020541/1/Tekkenshu_Sentai_Shinkenger Tekkenshu Sentai Shinkenger]], was written and published on various websites. Two years after the fanfic was finished, cue ''Series/SamuraiSentaiShinkenger''; this is even funnier due to all the times Chiaki/[=ShinkenGreen=] is shown playing ''VideoGame/{{Tekken}} 6: Bloodline Rebellion''.
* [[https://www.fanfiction.net/s/5950255/1/Power-Rangers-Public-Enemies Power Rangers Public Enemies]]
** The fic reveals that a Ranger team, the Power Rangers of the New Frontier, operated during the sixties. Then Boom! Studios comes along and introduces the 1969 Rangers sent on a mission to the moon.
*** The PRNF's Red Ranger, John Hill, serves as a paragon of sorts during his last moments before stopping the meteorite, effectively dying for the sake of humanity. Though she has yet to prove this, the 1969 Rangers' Red Ranger, Grace Sterling, proves to be a key ally to the Rangers despite rarely showing her powers again.
** George Sears shows fascination with regards to Hartford Industries' android technology. Jeremy Irons also revealed to have been dabbling into this side of Ranger tech as well. While it isn't for government purposes, ''Series/PowerRangersDinoFury'' would give us J-Borg, an android created by Hartford Industries nonetheless, and if things were to go by, it's far more commercially-used than the government-owned sect it would be portrayed as in the fic.
** The fic features a scene where [[spoiler: Rose kills Madison in an enclosed area]]. Look at it this way: the Blue Mystic Force Ranger and the Pink Operation Overdrive Ranger; swap the colors around, and though it's not exactly a Sentai, it does form the basis of ''Series/KikaiSentaiZenkaiger'''s ZenkaiOh VrooMagine. Not to mention how both of the characters composing said mecha are close teammates on their own.
** Three of the "Nameless heroes" in the fanfic [[spoiler: during the Rangers' civil war]] are named Troy, Amy, and Joe. The former would be the name of a later [[Series/PowerRangersMegaforce Red Ranger]] and the latter two would be used in Super Sentai in [[Series/ZyudenSentaiKyoryuger two]] [[Series/KaizokuSentaiGokaiger teams]].
** There is an [[TheAbridgedSeries abridged version]] of the fic, and in it, a sequel is detailed. The antagonist of the sequel is Power Lord Tommy, a version of the ''Power Rangers'' mascot that turned evil and stayed that way until the end. In other words...this fic predicted ''Lord Drakkon'' by seven years!
** One of the main catalysts for Billy's cynicism in the story basically amounts to [[spoiler: Trini's death at the hands of Count Dregon]]. [[spoiler: The Netflix special ''Once and Always'' has Trini's death as a plot point, and a key character arc in the story is how her daughter takes up the mantle. Not to mention Billy ''doesn't'' become a cynic and manages to persist through.]]
* The [[https://archiveofourown.org/series/2531404 Bugrangers]] fanfic series is based on an original bug themed Sentai team, and it was started long before ''Series/OhsamaSentaiKingOhger'' started airing.
** Even better, the fic's lineup included a female yellow mantis themed ranger, a butterfly themed female ranger, and a spider themed SixthRanger, all who made it into the official lineup.

[[folder: ''Western Animation/Teen Titans'' ]]

* Creator/DakariKingMykan's reasons for creating ''FanFic/TheEndOfEnds'' become extremely laughable when the finale to another one of his stories, ''Fanfic/CyborgDavis'', has an ending that's exactly like the ending to [[Recap/TeenTitansS5E13ThingsChange Things Change]].

[[folder: ''Series/Thats So Raven'' ]]

* ''Fanfic/{{Support}}'': Chelsea ends up pregnant by her abusive boyfriend and turns to her old friend Raven for support. ''Series/RavensHome'' later features an adult Chelsea and her child (a boy, not a girl like in ''Support'') living together with Raven, and her twins, after Chelsea divorces her implied-abusive husband.

* ''Series/TheVampireDiaries'' GenderFlip story, 'The Sara Diaries', features Stefan as a girl named Sara Salvatore. In Season Six, it was revealed that there actually was a Sarah Salvatore, Zach's long lost daughter.

Later materials in both ''Series/MsMarvel2022'' and the mainstream comics would reveal that Kamala is part-mutant.

[[folder: ''Franchise/Yu Gi Oh'' ]]

* ''WebVideo/YuGiOhTheAbridgedSeries'':
** In episode 27, Tristan states that [[Anime/YuGiOh5Ds "In the future, card games will be played on motorbikes."]] A few months later, Frank Frankson was revealed to be Yusei Fudo's voice actor.
** The Second Anniversary Spectacularthon had a few teasing shots at a couple [=VAs=]. I mean, no ''way'' Creator/VicMignogna would've watched it, recommended by a few of his Rangers, right? [[https://www.youtube.com/watch?v=Nejwl0QZlFs Wrong.]] Thankfully, he took it well and the two have met a few times since.
** Another one with LK and Vic -- for their first Kamicon promo, Martin calls him Creator/YuriLowenthal[[note]]Sasuke Uchiha from ''Manga/{{Naruto}}''[[/note]]. Vic voiced an Uchiha later in ''Shippuden''.
** Also, a good two years before the Abridged Series came out and made these types of jokes, the dub had a military captain in the Doma filler arc (who played the whole situation straight in the original) say that "as strange as it sounds, the fate of the world now depends on a card game."
** This:
--->'''Joey:''' Be careful, Yug. This guy means business. He wasn't even remotely intimidated by my Brooklyn Rage.\\
'''Yami:''' Joey, stop trying to turn 'Brooklyn Rage' into a catchphrase. It's never going to work.
*** [[https://www.youtube.com/watch?v=m0MHPYkmfh0 Take a wild guess on what Wayne Grayson's favorite line is?]]
** Episode 50: "Joey Wheeler Ace Attorney" had Joey up against the guy that banned the series twice already. The judge said that third time's the charm .. and a few weeks later, Little Kuriboh was temporarily suspended on Website/YouTube for the third time.
** Episode 25 featured a short sequence of Yami and Tea singing a duet, and the end stinger said 'that's the closest you're gonna get to yu-gi-oh: the abridged musical'. Several years and a ''lot'' of [[FilkSong cover songs]] later...

[[folder: Unsorted/Dormant/Dead ]]

* Written four years prior to ''ComicBook/SupermanRedSon'', ''Fanfic/SupermanAndMan'' has the [[Franchise/{{Superman}} Man of Steel]] wonder aloud: "What if Superman landed on a Communist country?"
* ''Fanfic/{{Starbound}}'': [[WhatCouldHaveBeen Originally]], chapter 6 was going to have an alternate opening scene involving Miyuki, after having finished a spinoff conversation with the twins from the others, spacing out and subconsciously [[FemaleGaze focusing her gaze further and further on Mondo's butt]] as her tendency to space out combines with a high state of sexual arousal following him and Rokuna showing themselves off in some skimpy swimwear to everyone just a few days earlier. The author was told that not only would this still be OutOfCharacter even with the setup, and that it not only does not equate with any of her previous blunders from the anime (which would result more from poor spatial awareness, hyper-immersion while reading, etc.) but said blunders are probably why she would be ''more'' careful not to act offensively, but that male and female sexuality do not even work the same way, with focus on anatomy being mostly a male thing. In a last-minute edit when Economy revised the entire chapter following his main beta-reader's return to business, Rokuna actually scoots behind Mondo to obscure her own body from Konata's view when she comments on how her PimpedOutDress could easily do with a CleavageWindow. Surely, that would've snapped Miyuki out of her gaze if she ''were'' to have gawked at Mondo in the first place.
* The ''Anime/DragonBallZ'' fanfic "[[https://www.fanfiction.net/s/130189/1/Atrocities Atrocities]]" features Goku getting possessed and turning evil thanks to a wish from the Dragon Balls, and causing his energy to get colored black. It's also a crossover with a few other series including ''Series/BuffyTheVampireSlayer'' and prominently features Spike. Over a decade and a half later, [[Creator/JamesMarsters Spike's actor]] [[Anime/DragonBallSuper voices a villain]] who uses the Super Dragon Balls to [[spoiler:switch bodies with Goku]] with the evil Goku being called Goku Black, who appropriately has black energy. You have to wonder if Toei and[=/=]or Funimation knew about this.
* ''Manga/RanmaOneHalf''[=/=]''Anime/PokemonTheSeries'' crossover [[https://www.fanfiction.net/s/16165/1/Fist-of-the-Pikachu "Fist of the Pikachu"]] has Ranma catch a Sandslash, and when he reaches Goldenrod City, his training causes it to evolve into a Steel-type new species. Its physical description is glaringly similar to Sandslash's Alolan form in ''VideoGame/PokemonSunAndMoon'', which also happens to be part Steel-type.
* A throw-away gag in WebVideo/BerserkAbridged44 has two [[StrawCharacter Strawman Political]] parodies arguing, which devolves into childish taunting, including the liberal one of the two calling the conservative parody a teabagger... this was made at the end of 2007, cue a certain political movement that appeared a year later.
* A NSFW [[WebAnimation/HomestarRunner Homestar/Strong Bad]] [[http://cartoon.adultfanfiction.net/story.php?no=544179072 slashfic]], somewhat infamous within the fandom, was reputedly written ''before'' the "Long Pants" email.
* In the ''VideoGame/FinalFantasyVIII'' fic [[http://ff.adultfanfiction.net/story.php?no=600080741 "Phantom Dreams"]], there's a joke about Zell's hair looking like a chocobo (and that's why Seifer called him a chicken) which was merely painfully unfunny until ''VideoGame/FinalFantasyXIII'' gave us a character with a chocobo living in his hair.
* In 2004, a [[UsefulNotes/FurryFandom furry-based]] anthology comic featured a mini-comic involving a lupine boy band who turns out to be secretly gay behind the scenes. Obviously, it's meant to parody the rumors of homosexuality within real boy band members at the time, but with the coming out of Lance Bass and the outing of Ricky Martin (though many don't know he was a part of Music/{{Menudo}}), you've got to wonder if the creator knew something we didn't. And, to make things even more hilarious, one of the band members in the comic is even named "Rickay"!
* ''Fanfic/YouGotHaruhiRolled'' is a ''Literature/HaruhiSuzumiya'' CrackFic. It has been running long before the preview to the tenth novel was even suspected, let alone released. In a chapter from before the preview, [[UncannyValleyGirl Kuyou Suou]], who could not talk without ridiculously-long pauses between words, is suddenly able to speak articulately and [[TheReasonYouSuckSpeech chew out the characters who made fun of her speech issues.]] Guess what happens in the tenth novel?
* A ''Literature/HarryPotter'' fanfic titled ''[[http://www.fanfiction.net/s/5755433/1/Gears_of_Potter Gears of Potter]]'' had Marcus Fenix and Dominic Santiago from ''VideoGame/GearsOfWar'' team up with Harry Potter and his friends. Then EA Games released the video game adaptation of ''Harry Potter and the Deathly Hallows'', which was basically [[RecycledINSPACE Gears of War with MAGIC SPELLS]].
* Early in ''Hogwarts Exposed'' Jamie unveils her pet, [[VideoGame/RobotUnicornAttack a robot unicorn with the power to chase away bad dreams.]]
* In the VisualNovel/KatawaShoujo fic "From Shizune's perspective," which was published before the full game was released, Shizune is surprised to find out that Emi is a lesbian, and Shizune says that "The track team captain being a lesbian is the sort of thing high school students would talk about," but that she gets left out of the loop because of her deafness. In Emi's route, while Emi is heterosexual, it turns out that the track team captain Hisao assumed was a romantic rival is [[IncompatibleOrientation gay]], and Hisao appears to be the only one who knows of the captain and yet is unaware of his sexuality.
* In episode 7 of ''FanFic/FutariWaPrettyCureDragon'', Hanzo Hattori (yet another fictional descendant of the RealLife UsefulNotes/HattoriHanzo), a self-proclaimed ''Franchise/StarWars'' fan, demonstrates a working model of a lightsaber. About one month after the episode was posted, [[http://www.swtorstrategies.com/2012/07/build-of-master-satele-shans-lightsaber.html?utm_source=zergnet.com&utm_medium=referral&utm_campaign=zergnet_27066 someone else made his own working model of a lightsaber in real life.]]
* The ''FanFic/NecromancersOfChinaSaga'', a series of ''Franchise/KungFuPanda'' {{fanfic}}s, tells about a group of necromancers that raise an army of the undead to take over China. One year later, this became the plot of the ''WesternAnimation/KungFuPandaLegendsOfAwesomeness'' episode, "The Po who Cried Ghost".
* [[http://magicrat.deviantart.com/gallery Magicrat of deviantART]] wrote a ''VideoGame/TeamFortress2'' fanfic where Teams RED and BLU join forces to battle the GRN team. Skip forward one year, and we now have Mann Vs Machine.
* In the second story of ''Fanfic/TheJillGilbertSaga'', [[spoiler: Bonnie]] sacrifices herself to bring Elena back to life. In the fourth season finale, she did end up sacrificing herself, but to bring back [[spoiler: Jeremy]]
* In early 2013, a fanfic was published that consisted of Music/SelenaGomez telling Music/BridgitMendler why [[Series/WizardsOfWaverlyPlace Alex and Juliet]] should be together. Bridgit remarks that a lesbian pairing would never happen on Creator/DisneyChannel. A few months later, it was announced Mendler's show ''Series/GoodLuckCharlie'' would feature a lesbian couple in its final season.
* Two fanfics by writer [=TakaiTotem=] -- ''[[https://archiveofourown.org/works/13197339/chapters/30188601 Send Read Receipts]]'' and ''[[https://archiveofourown.org/works/12053685/chapters/30985665 Peter Parker's Phone Calls]]'' -- have a chapter or two each revolving around a waterfowl who only seems to exist to create chaos for the protagonists, doing things like stealing objects and delivering [[CurbStompBattle one-sided beatdowns]] to them (keep in mind that all of our main characters are ''superheroes''). Sounds like a ShoutOut to ''VideoGame/UntitledGooseGame'' and the MemeticBadass reputation of its titular character...until you realize that the chapters he shows up in were written before the game was even ''announced''.
* ''Fanfic/BetweenMyBrotherAndMeMorsOmnibus'' has Xavier (using a Fabled deck) fighting off against Yuzu and questioning why Fabled didn't have better support, particularly in the Spell and Trap department. The chapter was updated around the time the ''Blazing Vortex'' booster pack was revealed that has more Fabled support and both a dedicated Field Spell and Trap card for it.
* ''Fanfic/BoysUndSenshado'' adds two new tank crews of male {{original character}}s -- Shark Team and Alligator Team -- to Oarai's roster. In ''Anime/GirlsUndPanzerDasFinale'', there's a new crew of (female) {{delinquent}}s called Shark Team.
* ''[[https://www.fanfiction.net/s/1074226/1/Golden-Darkness Golden Darkness]]'' by Matita Pere is a fanfic written in 2003, set in Tolkien's Legendarium, and probably the oldest known fanfic about Galadriel and Sauron being love interests. The premise of the fanfic is about Sauron, under the disguise of Annatar, who is in Eregion, manipulating the Elves to create the rings of power while developing a VillainousCrush on Galadriel. Two decades later, Amazon creates ''Series/TheLordOfTheRingsTheRingsOfPower'', where Sauron under the disguise of a human, has the hots for Galadriel while trying to create the rings of power. Of course that Sauron and Galadriel became over the night one of the most popular ships in the Lotr fandom. That fanfic writer must be very happy now for predicting Sauron/Galadriel.
