{{Fanfiction}} is a popular medium, and thanks to the nature of SturgeonsLaw, some of it can indeed be quite good to read.

And some of that fanfiction may actually become so interesting to some readers, that those readers are inspired to write fanfiction based on those stories, despite the fact (or perhaps ''because'' of it, in some cases) that the original story is fanfiction in and of itself…

This is '''Recursive Fanfiction'''.

Care should be taken with this trope, as the story that said fanfic is based on ''must'' be a fanfiction as well. If the fiction that it is based on is not itself based on another work of fiction, then that’s a normal FanFic, and not this trope.

Or, schematically:

Original fiction → regular fanfiction → Recursive Fanfiction → still Recursive Fanfiction, but of a higher (deeper?) level.

Not to be confused with MetaFic. When fan fiction spawns enough recursive fan fiction set in the same continuity, a FanVerse is born.

[[folder:Anime and Manga]]
* ''FanFic/NobodyDies'' has several sidestories written by both the author and others, including ''Six [=AIs=], One Continent'' and ''The Kei Files''.
* ''[[FanFic/KyonBigDamnHero Kyon: Big Damn Hero]]'' has [[http://www.fanfiction.net/s/7106575/1/ Traveller]].

* ''[[FanFic/NeonGenesisEvangelionR Eva-R]]'' has ''[[http://fanfic-mausoleum-n-grill.dreamwidth.org/tag/evangelion+redemption Evangelion: Redemption]]''.
* The ''Manga/DeathNote'' fandom has at least two fanfics that inspire recursive fanfiction:
** [[http://www.fanfiction.net/s/3813281/1/Poison_Apple Poison Apple]] by RobinRocks and Narroch has five: [[http://www.fanfiction.net/s/4823586/1/Human Human]], [[http://www.fanfiction.net/s/6807006/1/Doom Doom]], [[http://www.fanfiction.net/s/6807013/1/My_love My love]], [[http://www.fanfiction.net/s/7339651/1/The_End The End]] and [[http://www.fanfiction.net/s/4304231/1/Broken_Fairytale Broken Fairytale]].
** [[http://www.fanfiction.net/s/5154854/1/PITCH PITCH]] by uberneko-zero has two: [[http://www.fanfiction.net/s/7274051/1/A_Different_Shade_of_Pitch A Different Shade of Pitch]] and [[http://www.fanfiction.net/s/6836104/1/Lips Lips]].
** [[http://www.fanfiction.net/s/3529129/1/ True Elision]] very recently inspired a KinkMeme fill: [[http://www.fanfiction.net/s/7595429/1/The_End The End]] which in turn got its own sequel [[http://www.fanfiction.net/s/7543896/1/Heart Heart]]. Ironically, the first two [[{{GuyonGuyIsHot}} are yaoi]] and the last one is {{Het}}.
** ''Fanfic/LightAndDarkTheAdventuresOfDarkYagami'' has inspired several fan sequels: [[http://www.fanfiction.net/s/9793696/1/Light-and-Dark-Returning-of-D-ark Returning of D'ark]], [[http://www.fanfiction.net/s/9232528/1/Light-and-Dark-DEUX-The-New-Adventures-of-Dark-Soichiro Light and Dark DEUX]], [[http://dn-kink2.livejournal.com/1491.html?thread=1606355 SAD GOODBYES]], and a RoundRobin [[http://dn-kink2.livejournal.com/1491.html?thread=1638099 post game]].
* [[http://lesswrong.com/lw/18g/the_finale_of_the_ultimate_meta_mega_crossover/ The Finale of the Ultimate Meta Mega Crossover]] technically counts, since it contains references to at least three different fanfics ("Thousand Shinji", "Shinji and Warhammer 40,000", and "Once More With Feeling"). However, it's more notable for being infinitely self recursive.
* [[http://www.fanfiction.net/s/1230438/1/Shadow_League Shadow League]] is a fanfic based off the infamous DarkFic ''FanFic/PokemonMaster'', amongst countless others.
* Say what you will about the infamous ''AxisPowersHetalia'' "Economic Crisis Gangbang" KinkMeme fill and its [[RapePortrayedAsRedemption content]], but it proved popular enough to spawn a plethora of spinoffs about America's PTSD after the event, what would have happened if the other nations had mistaken Canada for America or if America had [[ForgotICouldFly actually put his]] SuperStrength [[ForgotICouldFly to good use]] or [[WhatTheHellHero chewed out the other nations for their heartlessness]], a consensual or at least less disturbing version of it, etc.
** The TearJerker ending of the US/UK [[{{Doujinshi}} doujin]] ''Silencer'' affected some readers enough to write/draw FixFic for it.
** The infamous {{Gorn}} fic ''Debt'' has a recursive parody fanfic written by its own authors, in which the first chapter is rewritten as a cosplay game GoneHorriblyWrong in which the China cosplayer turns out to be a psychopath and breaks out the knives. Taking this as an implication that the writers wouldn't mind it being parodied (particularly since they expressed pride that the original ''Debt'' nearly ended up on the SoBadItsHorrible page), someone made a [[http://chelonianmobile.deviantart.com/art/Repaid-292831424?q=gallery%3Achelonianmobile&qo=3 fanart piece]] depicting China confronting his VillainSue replacement (not work safe for swearing, blood, and suggested extreme violence).
** Not to mention all the fanfics on what the ending could've been for HetaOni...
** ''FanFic/HumanCuriosity'' has a prequel fic, ''What Curiosity Brings'', which is being written with permission by the original fanfiction's author.
* ''FanFic/DungeonKeeperAmi'' has spawned several of these (though most of them are short one-shots).
* ''Fanfic/InFlight'' has spawned several spin-offs, most notably ''Fanfic/TheEmiyaClan''.
* The ''LightNovel/DirtyPair'' fanfic ''[[http://www.fanfiction.net/s/157673/1/I-Am-One I Am One]]'' by Sean Gaffney is a followup to Larry Mann's [[WordOfDante influential story]] ''[[http://www.eyrie.net/ETC/DP/E-101E/Experiment101.txt Experiment 101-E]]''. (The story covers the same basic ground as the sequel Mann co-wrote with Ryan Matthews, ''[[http://www.eyrie.net/ETC/DP/Reunions/ Reunions]]'', but goes in a different direction.) Gaffney's sequel to ''I Am One'', ''[[http://www.fanfiction.net/s/228050/1/Won-t-Get-Fooled-Again Won't Get Fooled Again]]'', raises the stakes on this trope by including several other authors' Dirty Pair original characters as cameos ([[FusionFic along with the multiple]] [[IntercontinuityCrossover crossover characters]]).
* ''[[{{Fanfic/BoyScoutsOneHalf}} Boy Scouts ˝]]'' is a ''RanmaOneHalf'' ElsewhereFic centering on a group of SelfInsert characters from Massachusetts. When three acquaintances of the creator of ''Boy Scouts ˝'' were given cameo appearances in one story, one of those acquaintances began a [[{{Main/Spinoff}} spinoff]] series called ''Perspectives.''
* ''Fanfic/GameTheory'' served as a large inspiration for ''[[http://forums.spacebattles.com/threads/ragazza-magica-renza-veneti-pmmm-lyrical-nanoha-fusion.247741/ Ragazza Magica Renza Veneti]]'', a crossover with ''Anime/PuellaMagiMadokaMagica'', though more in the way of setting than plot.
[[/folder]]

[[folder:Film]]
* ''FanFic/ThePrivateDiaryOfElizabethQuatermain'' apparently has several.
* The ''[[{{FanFic/LostInTimeSeries}} Lost in Time Series]]'' has one called ''Lost in Time: Destiny''.
* The well-known ''Film/HowToTrainYourDragon'' fanfiction ''Fanfic/{{Hitchups}}'' got one, a oneshot based off the story with the author's permission called ''The Elder's Prediction.''
* This occurs at least three times in Disney/TheLionKing fandom:
** ''Fanfic/TheLionKingAdventures'' is the most famous example, with no shortage of fan fiction being made by the fans. Even the [[{{Spinoff}} spin-offs]] have fanfics.
** "Chronicles of the Pridelands" invented the character Tanabi, Simba’s son. Nearly every TLK fan began using the character in their own {{Next Gen Fic}}s. His popularity soon declined though, due to the release of the semi-official Six New Adventure book series, which gave Simba a different son, Kopa. The release of the second film with the arrival of Kiara made all but the oldest fans forget Tanabi.
** [[http://tlk-fancomics.deviantart.com/gallery/42286638 Joanna-TLK’s fancomic]] continues on from the last chapter of [[http://tlk-fancomics.deviantart.com/gallery/?set=30863120&offset=0 Savu0211’s fancomic]], which by then, had almost nothing to do with the original films.
[[/folder]]

[[folder:General/Crossovers]]
* ''[[http://www.equestriadaily.com/2011/08/fallout-equestria-project-horizons.html Project Horizons]]'' by Somber -- a Recursive Fanfiction for the WesternAnimation/MyLittlePonyFriendshipIsMagic[=/=]{{VideoGame/Fallout}} crossover fanfiction ''Fanfic/FalloutEquestria'' by Kkat -- has already spawned fanfiction of its own.
* ''[[Fanfic/DrunkardsWalk Drunkard's Walk]]'' has inspired a number of fanfics, collectively known as ''The Drunkard's Stagger''.
* ''EdventureOfTheThousandYearDoor'' has ''[[http://www.fanfiction.net/s/7145922 As This Train Goes]]'', a WhatIf fic asking what would happen if Sarah was the legendary hero and if Edd and the others weren't charged of collecting the Crystal Stars. Sadly, it's a DeadFic.
* ''WebAnimation/TurnaboutStorm'':
** {{Invoked|Trope}} for the "[[IncrediblyLamePun Wright]] a Bad Ending" contest, where fans were invited to write what would have happened if no one had shown up to save the day [[DarkestHour when everything seemed lost]].
** Many fan works based on the series have been made, including [[http://youtu.be/OP5JNpe6j_o a cancelled spin-off]], [[http://www.fimfiction.net/story/6177/phoenix-wright-turnabout-storm an unofficial novelization]] that adds an InterspeciesRomance subplot, and several {{Fan Sequel}}s.
* The MegaCrossover FanWebcomic ''Webcomic/{{Roommates}}'' has a whole ExpandedUniverse worth of fanfiction based on it called the ''{{Franchise/Buildingverse}}''. With five separate spin-offs (''Webcomic/GirlsNextDoor'', ''Webcomic/DownTheStreet'', ''Webcomic/{{Superintendent}}'', ''Webcomic/MeanwhileUpstairs'' and ''Fanfic/OnlyADream'') having trope pages and if we wanted to be perfectly precise ''Webcomic/DownTheStreet'' is a ''Webcomic/GirlsNextDoor'' fancomic.
** To make things even more complicated a lot of these works add even more {{Crossover}}s or take characters / concepts from yet other fanfiction creating a TangledFamilyTree that rivals the magical people's[[note]](In this 'verse each and every magical being from every fanon EVER is related somehow)[[/note]].
** And then there's the fact that ''Webcomic/{{Roommates}}'' [[AscendedFanon sometimes uses ideas and OCs from]] ''Webcomic/GirlsNextDoor'' (and its other spin-offs), to the point where they could almost be considered fanfics for ''each other''.
** To make it "clearer" a flowchart of the relationship between the three main troped ones (misses ''Meanwhile Upstairs'' and ''Only A Dream'' also adding all would be bad for sanity) and the world [[http://static.tvtropes.org/pmwiki/pub/images/Building-verse_relationships_6402.jpg here]]. Block arrow main relationship, normal arrow other influence / ascended fannon / etc..
* ''FanFic/BetterLivingThroughScienceAndPonies'' spawned a Chapter 4.5.
** There is now ''[[http://www.fimfiction.net/story/109545/a-trusted-friend-in-science-and-ponies A Trusted Friend in Science and Ponies,]]'' which is a direct sequel.
* ''FanFic/TheInfiniteLoops'' loves to play with fan concepts, having loopers discover a variant of their own reality based on fanon and a few fanfics. The My Little Pony loops even bring [[FanFic/PastSins Nyx]] into the cast, and Twilight flat out states they do not talk about [[FanFic/TheConversionBureau the bureau.]]
* ''Fanfic/AceCombatEquestriaChronicles'' has a spin-off, ''[[http://www.fimfiction.net/story/116859/ace-combat-gryphon-wings Ace Combat: Gryphon Wings]]'', which takes place ten months after ''The Equestrian War'' and serves as a tie-in between the two main stories.
[[/folder]]

[[folder:Music]]
* There are multiple fanfics based around ''Act 1'' and ''The father of Death'' by Music/TheProtomen. Which themselves are a set of two [[DarkFic Dark]] AlternateUniverse Fics based on the original ''VideoGame/MegaMan'' game.
[[/folder]]

[[folder:Newspaper Comics]]
* There's a lot of unofficial [[Fanfic/TheCalvinverse Calvinverse]] stories out there. Among them is ''Fanfic/ThePezDispenserAndTheReignOfTerror''.
[[/folder]]

[[folder:Literature]]
* ''Fanfic/HarryPotterAndTheMethodsOfRationality'' has not only inspired its own fanfics, such as ''Once Upon a Tower'' and ''Nightmares of Azkaban'', but "Rational" fics have become a kind of sub-genre.
** The most famous Rational fic beside ''Methods'', ''FanFic/{{Luminosity}}'', has spawned several fan short stories.
* The large ''Literature/HarryPotter'' projects ''The Shoebox Project'', ''Dumbledore's Army and the Year of Darkness'' and the Fanfic/{{Dangerverse}} have their own fanfic.
* All the sequels to ''MyImmortal''.
* Fanfic for ''Literature/{{Wicked}}'' is recursive, since the book is a derivative work (like fanfic, but it's legal to publish) of TheWizardOfOz. And fanfic for the musical would be...fanfic for a musical based on a book based on a movie based on a book.
* ''Fanfic/HarryPotterAndTheNightmaresOfFuturesPast'' has inspired [[https://www.fanfiction.net/s/10213764/1/ G for Ginevra]].
* The ''Literature/HarryPotter'' fanfic [[https://www.fanfiction.net/s/2318355/1/ Make a Wish]] was the inspiration for [[https://www.fanfiction.net/s/9510186/1/ Terminal Justice]].
[[/folder]]

[[folder:Live Action TV]]
* There are quite a few stories written by authors other than the original CP Coulter that use original characters from the ''{{Glee}}'' fanfic ''Dalton''.
* ''TheHarmonverse'', a series of ''{{Glee}}'' fanfics centred around the OriginalCharacter of Jack Harmon. It includes four ongoing novelizations of ''{{Glee}}'' and over 40 stories altogether.
* ''Fanfic/TheContract'' has ended up spawning a number of other fanfics, forming [[TheVerse a world]] known as the Contractverse. They include:
** ''[[http://www.fanfiction.net/s/2896318/1/Lifeline Lifeline]]'', a companion piece to ''The Contract''.
** ''[[http://www.fanfiction.net/s/3388312/1/Exigencies Exigencies]]'', a ContinuationFic for ''The Contract''.
** ''[[http://www.fanfiction.net/s/3428758/1/ Recovery]]'', ''[[http://www.fanfiction.net/s/3557391/1/ Where the Rails Converge]]'', and ''[[http://www.fanfiction.net/s/5092702/1/A_Gentle_Knock_at_the_Door A Gentle Knock at the Door]]'', all separate sequels to ''Exigencies''.
** ''[[http://www.fanfiction.net/s/5412732/1/PATIENT PATIENT]]'', a sequel to ''A Gentle Knock At The Door''.
** ''[[http://diysheep.livejournal.com/20287.html#cutid1 Creepy Pencil Story]]'', a short "What-If" story,
** ''[[http://alex51324.livejournal.com/32577.html Pencils are Dangerous]]'', a sequel series to ''Creepy Pencil Story''.
** ''[[http://www.fanfiction.net/s/5299378/1/The_Kindness_of_Strangers The Kindness of Strangers]]'', a oneshot addition to ''Pencils are Dangerous''.
* ''[[http://archiveofourown.org/works/180121/chapters/264839 Two Two One Bravo Baker]]'', a military ''[[Main/AlternateUniverseFic AU]]'' of the ''Series/{{Sherlock}}'' universe, has spawned its own works of fanart and fanfic.
* Series/TheMightyBoosh fandom has several rather famous fanfictions, notably Stockholm Syndrome, that were so popular that they spawned countless fanfictions based on it from other authors. The number of fanfictions and fanarts based on Stockholm Syndrome ballooned after it was revealed Creator/NoelFielding himself was a fan of the fanfiction and inserted references to it into a live performance.
[[/folder]]

[[folder:Video Games]]
* There's been at least one doujin based on ''[[VideoGame/PatchCon PatchCon! Defend the Library!]]''.
** People seems to like the concept of [[AdventChildren Advent]] [[RecycledINSPACE Cirno]] a lot, and there are a lot of fanarts of it in {{Pixiv}}.
* ''PokeWars'' has spawned at least ''twelve'' fics based on Cornova's world.
** Another ''{{Pokemon}}'' example: there have been multiple fanfics written based on ''BlackAdventures''.
** And a huge community based on ''Fanfic/{{Pokeumans}}'', with literally hundreds of members.
* The ''VideoGame/{{Portal}}'' fandom is involved in a [[http://dl.dropbox.com/u/29956148/doodles/2012-01-15%2016.40.54.jpg rather complex graph]] of RecursiveFanfiction. From top to bottom:
** ''Webcomic/{{Homestuck}}''; ''Videogame/{{Portal}}''; ''Videogame/TeamFortress2''
** ''Portal'' [[http://www.moddb.com/games/portal/mods mods]]
** ''[[FanFic/PortalThe4thMillenniumFranchise Portal: The 4th Millennium]]''; ''[[FanFic/{{ITSMYLIFE}} ITS MY LIFE! & TEEN FORTRESS 2]]''
** ''[[http://www.fanfiction.net/s/7158102/6/The_Inevitable_Sunset The Inevitable Sunset: An Impossible Continuation]]''; [[TheHalfWorld Skepkitty's MSTs]]; [[http://www.fanfiction.net/s/7187436/1/MarissaxChell MarissaxChell]] & Portla 3 (LostForever)
** [[http://trollinmahpantz.wordpress.com/ HIT THE BERSERK BUTTON! MSTs]]
** And that's only counting 2011. 2012 brought us fictional ''Horrible Fanfictions'' and ''Portal: The 4th Millennium: The {{Trollfic}} [[https://docs.google.com/document/d/1f2-6gM-bSu2gyHQnFzg6ZybsgPXVCvh0TdhkssXFWzY/edit Edition]]''.
* ''[[http://forums.darknestfantasyerotica.com/showthread.php?260-Ethereum-Gladiator-Kynrind-s-Capture Kynrind's Capture]]'' is one based on the PornWithPlot ''VideoGame/{{Warcraft}}'' fic, ''Ethereum Gladiator''.
* Subverted with ''FanFic/{{Morphic}}'', where a new author was supposedly going to write his own sequel to the original fic... only it turns out the whole thing was planned out ahead of time by the original author as part of an elaborate April Fool's prank.
* The ''VideoGame/{{Oolite}}'' project is a FanRemake of ''VideoGame/{{Elite}}'', so all ''Oolite'' fan works are essentially ''Elite'' fan works by proxy. Additionally, the game is also highly moddable; well-received [[GameMod Oolite Expansion Packs]] inspire authors to incorporate their features into their fics, and new ideas from fanfic writers in turn inspire new [=OXPS=]. Furthermore, developers and community regulars frequently [[{{Tuckerization}} include versions of one another's in-game personas]] in their own fan works.
* Hang around an active GameMod community long enough and eventually you'll start seeing mods of mods.
[[/folder]]

[[folder:Web Comics]]
* {{Homestuck}} out the wastechute. Fans will create alternate universes, the alternate universes will become popular, people will write fanfics set in the alternative universes... and then there's the ''fanart'' of alternative universes.
** TheGrandBattle is the most notorious in having fanart and other fan stuff based on itself.
** There is genderbent fanart of a cosplay of a fanart of a memetic guy that randomly got into a picture of cosplay.
* ''Unwanted Free Ugly Troll'' gets one in ''Loophole''.
[[/folder]]

[[folder:Web Original]]
* There is a [[http://www.fanfiction.net/community/Yu-Gi-Oh_The_Abridged_Series_Fanfiction/80293/ whole community]] of people writing fanfiction based on ''WebVideo/YuGiOhTheAbridgedSeries''.
* ''WebVideo/VaguelyRecallingJoJo''
** There's a edit of Jean Pierre Polnareff in VideoGame/{{MUGEN}}, which uses Polnareff's OhCrap face and vanilla.ice's voice and sounds.
** A fan also recreated the scene where they confronted the truck in the Miku Miku Dance 3-D modelling program.
* Much, if not most, of the fanworks in the [[Creator/ThisIsIt Don't Hug Me I'm Scared]] fandom are based on a particular piece of fanart depicting the Clock and the Notepad [[HumanityEnsues in humanoid form]], and center around their [[{{Flanderization}} flanderized]] {{fanon}} personalities, which really have [[InNameOnly nothing much to do with the original videos]].
[[/folder]]

[[folder:Western Animation]]
* ''WesternAnimation/AdventureTime'' has an InUniverse example. Ice King wrote a Rule 63 fanfic of the show, in the episode "Fionna and Cake." The episode "Bad Little Boy" has Marceline then writing her own continuation of it. Followed by LSP in "The Prince Who Wanted Everything".
* ''WesternAnimation/MyLittlePonyFriendshipIsMagic,'' due to the inescapable hold over the Internet it had for a while, has had several of these:
** There's the ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' fanfic ''FanFic/TheConversionBureau'', which has spawned ''tons'' of [[http://www.equestriadaily.com/2011/04/conversion-bureau-compilation.html fics set in the same setting or a variant thereof]]; no wonder, since it is a very convenient setting for WishFulfillment and satisfying one's desire to live in the story. Its [[HumansAreTheRealMonsters misanthropic]] [[PunyEarthlings tone]] has, however, spawned responses like ''Fanfic/TheConversionBureauNotAlone''.
** ''FanFic/FalloutEquestria'' has a [[http://fallout-equestria.com/stories number of sub-fics]]. Though that's understating the case: "a number of sub-fics" means ''over 200'' of them. The most notable is ''[[FanFic/FalloutEquestriaProjectHorizons Project Horizons]]'', which has even spawned fanfic of its own.
** ''FanFic/{{Cupcakes}}'' has several alternate ending fanfics written, and a few sequels.
** ''{{Fanfic/FiveScoreDividedByFour}}'' has tons.
*** [[http://www.fanfiction.net/s/7284396/1/Rainbow_Leap Rainbow Leap]] is a ''Series/QuantumLeap''-inspired ponyfic wherein Rainbow Dash tries to fly faster than ever [[FandomSpecificPlot with some]] AppliedPhlebotinum [[FandomSpecificPlot from Twilight Sparkle]], and ends up dimension travelling through not only ''Cupcakes'' but several of the fanfics based on it, making it a recursive recursive fanfic.
** ''{{Progress}}'', focused on [[OCStandIn Princess Luna]] adjusting to the changes in Equestrian society over the last thousand years, has inspired ''[[https://docs.google.com/document/d/1CmPYe0YbUOokWei-j_qVp7FeB7EKy7znwOfQZvze6bE/edit?hl=en_GB Luna Vs. Videogames]]'', ''[[http://www.fanfiction.net/s/7377858/1/FiM_Progress_Celestia_vs_Time Celestia vs. Time]]'', and the {{NSFW}} ''[[https://docs.google.com/document/d/1xbFwj2RnKEnN_EqUJ71nHk2DqwD7sYYgSCRkka_5PE8/edit?hl=en_US Luna Vs. Threesome]]''.
*** Luna having an abacus is mentioned in several otherwise unrelated fics.
** ''{{Fanfic/Silent Ponyville|Chronicles}}'' has gone on to spawn at least ''three'' different fanon continuities, some of which have had a [[AscendedFanon significant influence]] on the central continuity. Also has a [[http://silentponyville.deviantart.com/ DeviantART group]] with plenty of fanon works.
** ''The Fanfic/PonyPOVSeries'' has spawned [[http://c8lin-the-hedgie.deviantart.com/art/Discorded-Ponies-HaterSketch-263929712 another Discorded Ponies Series fanfic]] and [[http://teyandee05.deviantart.com/gallery/33150793 The Letters To Ponies]] series.
** ''FanFic/{{Xenophilia}}'' has [[FanFic/IntoTheHedge gone]] on [[FanFic/DividedRainbow to spawn]] a [[http://www.fimfiction.net/story/67231/xenophilia-further-tales significantly]] [[http://www.fimfiction.net/story/115322/xenophilia-advanced large]] [[http://www.fimfiction.net/story/70619/no-room-for-regret number]] of [[http://www.fimfiction.net/story/107717/xenophilia-flesh-and-thorns other]] [[http://www.fimfiction.net/story/57315/the-xenophiles-guide-to-equestria recursive]] [[http://www.fimfiction.net/story/103616/xenophilia-shotglass-oneshots stories.]]
** Also, ''VideoGame/StoryOfTheBlanks'' is referenced as a real occurence in a lot of fanfiction.
** A couple of fics are set after ''FanFic/PastSins'', though it's usually just an excuse to use Nyx without being a direct sequel to the story. ''FanFic/RealityChecksNyxverse'' is very much a sequel.
** Each chapter of Fanfic/TheSweetieChroniclesFragments is set in the universe of a different pony fanfic. Stories covered so far include ''Fanfic/OfMaresAndMagic, Nightmares Don't Last Forever, The Light Never Goes Out, Fanfic/OnACrossAndArrow, Fanfic/FalloutEquestriaPinkEyes, Fanfic/TheBestNightEver'' and ''Fanfic/TheImmortalGame'', and the second April Fools episode takes a turn through several of the author's own other stories. Furthermore, ''Fanfic/ThisPlatinumCrown'' (the sequel to ''The Best Night Ever'') is said to treat the events of that chapter as canon.
** ''FanFic/FriendshipIsOptimal'' has a group, [[http://www.fimfiction.net/group/1857/the-optimalverse “The Optimalverse”]], for its fanfiction. Several stories also have their own pages, including ''FanFic/FriendshipIsOptimalAlwaysSayNo'', ''FanFic/FriendshipIsOptimalCaelumEstConterrens'', ''FanFic/FriendshipIsOptimalTheLawOfficesOfArtemisStellaAndBeat'' and ''FanFic/LetsPlayEquestriaOnline''.
** ''TheLifeAndTimesOfAWinningPony'' has its own group to handle spinoffs and derivative works.
** And ''[[EakinsHardReset Hard Reset]]'' picked up a fanfic picking up ... um ... somewhere in the mess. ''Hard Reset 2: Reset Harder'' splits off on the premise that why should Twilight be the only one who gets the GroundhogDay treatment?
** Topping everything off, we have fanfics about the ''canon in-universe'' fanfic that the canon Rainbow Dash was writing in ''Spike At Your Service''.
** ''Fanfic/CrisisOfInfiniteTwilights'' is a rare one that is a recursive fanfiction that has also created Recursive Fanfictions.
*** The story itself includes appears of ''Fanfic/FaithandDoubt Faith and Abstract Twilight'', Nyx, and Lunaverse Twilight.
*** It has also caused the creation of several other fics, including ones based on Twiley and Green Lantern Twilight.
** ''Fanfic/AllAmericanGirl'' likewise has [[http://www.fimfiction.net/group/202027/the-allamerican-girl-saga its own group]], with a handful of third-party stories set in its universe.
* The ''{{Daria}}'' fanfic ''GodSaveTheEsteem'' has spawned a prequel, ''Moving Pictures'', as well as numerous other stories up to and including the obligatory lesbian SlashFic.
** They both started being written at around the same time, so it's more likely that it's two different, but similar series that ended up sharing their continuity.
* The KimPossible fanfic ''A Small Possibility'', with the author's given permission, has spawned many a Kim/Shego fanfic featuring their spawn from the original, Kasy Ann and Sheki Go.
* The fanfic ''{{Fanfic/Strays}}'', hosted in the ''WesternAnimation/YoungJustice'' KinkMeme, has several future-fics set to it and attached its thread despite the story still being in its early stages and in the process of being fleshed out. There is also fanart for it, featuring the costume designs for the Batkids' new hero identities.
* [[http://kateboat.deviantart.com/art/Fixed-331610708 This]] ''{{Superjail}}'' one-shot fic is actually a sequel/epilogue to ''[[http://www.fanfiction.net/s/6079358/1/Fix-You Fix You]]'', written with the original author's given permission of course.
** ''[[http://www.fanfiction.net/s/9742382/1/Et-Mundus-Eos Et Mundus Eos]]'' is a sequel to ''Fanfic/ExtendedStay'', written with the original author's consent.
* PhineasAndFerb fandom has a NextGenFic pairing that many people have taken to writing fanfic for, Thomas Fletcher (son of Ferb and Vanessa) and Marie Garcia-Shapiro Flynn (daughter of Phineas and Isabella). They have their own PortmanteauCoupleName (Thomarie) and a ton of art for them on DeviantArt. There's even artwork of them signed by the Latin-American voice actors for the show.
* In the ''WesternAnimation/GoofTroop'' fandom, there are several stories based on one fan's extensive mythos surrounding an AlternativeCharacterInterpretation of [[JerkJock Bradley Uppercrust]]'s backstory (specifically one that makes him a JerkassWoobie); ''[[http://www.fanfiction.net/s/8439426/1/Turning-Back-Time Turning Back Time]]'' is one such story that [[AdaptationDisplacement seems to be better-known than anything the original author did]].
