Fan Verse

Go To

When a fanfiction writer, or group of writers, do several (not just a few, several) fics for the same fandom taking place in the same continuity as each other, that's a Fan Verse. Another variant of this is when you have a few stories that utilize a popular Fandom-Specific Plot and become so well-loved themselves that several other writers treat them as a framework from which they base their own stories on, creating their own Recursive Fanfiction. The original fanfic writer may or may not then acknowledge these as being part of their continuity. Any fanfic that has a copious amount of worldbuilding counts a lot toward this label as well.

If they keep it coherent and get enough interest, Fan Verse writers can single-handedly influence Fanon, possibly to the point of being canonized as an Expanded Universe. Compare Shared Universe.

    Anime and Manga 
  • Legacy Of The Rasengan by Tellemicus Sundance has spawned its own fan verse in recent years, especially now since he has given up on Chuuten and has chosen a successor to continue it.
  • The Sailor Moon Expanded community was a prime example of a Fan Verse. The writings of over a dozen authors were combined with the goal of adding new and interesting characters, stories, and information to the Sailor Moon universe without contradicting established canon. In many instances, particularly in the works of Mark Latus, the expanded material is more interesting and concise than the original source. It hasn't been updated with new material in quite some time, however.
  • Richard Lawson created two such Fan Verses for Ranma ½ during the late 1990s:
    • Thy Inward Love is a continuation fic that picks up at the end of the Ranma manga and attempts to resolve the series' Love Dodecahedron and corresponding web of honor entanglements; in addition to the main storyline there are several prequels and side stories, and a sequel series.
    • Thy Outward Part is an Alternate Universe Fic where Ranma is locked in female form permanently in the wake of a different, more tragic outcome to the Chisuiton arc of the manga. Pushed away by Akane, Ranma goes to college alone and unhappy, until she meets a young man who finds her attractive and wants to learn martial arts from her. Long thought to be "closed", this 'verse was revived when Lawson started writing stories in it again.
    • Lawson has also written a series of five All Purpose Cultural Catgirl Nuku Nuku fics that describe the remarkable life and evolution of the ostensibly comedic title character.
  • There is a truly awesome one of these for Urusei Yatsura called ''The Senior Year'', started by Fred Herriot. It takes the original setting, characters and runs with them, adding new and interesting characters, places, cultures (including many ShoutOuts to other anime) and spans at least 20 years through its various sequels.
  • The Neon Genesis: Goddess series by Slayer combines Neon Genesis Evangelion and Ah! My Goddess for an interesting effect on the story of NGE. It also has about two dozen spinoffs and continuations.
  • Neon Genesis Evangelion R was all written by one author but it has two branching continuities and has itself spawned fan fiction (such as Neon Genesis Evangelion: R: Redemption). It's also unusually detailed for a piece of fan fiction and elaborates substantially on the nature of the Angels compared with the original series.
  • The Superwomen of Eva series (of which Superwomen of Eva 2: Lone Heir of Krypton is one example) has several stories that cross over amongst themselves (in a very Broad Strokes fashion), creating a shared universe (and a few alternate universes to the two "main" ones). Of interest is that the series has two different shared universes, one which takes inspiration from Marvel Comics and one which takes inspiration from DC Comics.
  • MegaTokyo has spawned at least three Fan Verses to date. The oldest is the MegaTokyo: the Clans game that started in 2001 on the MegaTokyo Forum, and which is still going (look for threads labled [Mt:tC] in the RP subforum). More recently is the Story Discussion Fanworks game that is hosted off site in its own dedicated forum. Most recently is the energetic Megatokyo Campfire Story that can be found in the fanart subforum.
  • In Naruto fandom, the Lace and Strawberries or Saki-chan Fan Verse, started by Asuka Kureru or Askerian. The basic premise is Sasuke dealing with his issues via cross-dressing as a Gothic Lolita that goes by the name of Saki. Not actually crack. While she has written only three fics in this verse, the number of fan-fan works has possibly reached triple digits, and includes writers such as chibirisu-chan, ice-dark elf, and crazy-toffee.
  • The Continuance of Haruhi Suzumiya by Hejin57. This series branches directly off the anime adaptation of The Melancholy of Haruhi Suzumiya. Starting with The Attraction of Haruhi Suzumiya, this story has already seen three completed sequels, and another already in the works. Set for six stories in total, this fanfic series easily qualifies as a fan verse. All the stories in the series are great, too!
  • One Piece has one in the Crew of the Axe due to the main fanfic crossing over with several other fics, and those fics crossing over with more fics.
  • The very NSFW fan verse Wild Horses and Pokegirls where Ranma is sent to a very twisted Pokemon altverse where, at some point in history, women were crossed with pokemon so that now, everyone has some level of poke DNA, and very few girls look human, especially after puberty. Those that do, don't usually stay that way for long. It's very much a fetish fanfic crossover, but it's been around for a long time and spawned many storylines, including multiple interactive "Choose Your Own Adventure" style stories.
  • Debbie (Dai-chan) began The Powers of Crests universe for the Digimon fandom on FanFiction.Net, which was expanded upon by Creedogmon, and an author named DayDreamer9 has begun a third imagining.
  • The 1983: Doomsday Stories AU for Hetalia: Axis Powers has expanded to included contributions from other artists and authors.
  • The Ranma ½ Elsewhere Fic Boy Scouts ½ has had multiple authors (many of whom are also Self Inserted characters, some before writing and some after), and has two Spinoffs and a Sequel.
  • An author named Kanius has a set of fan-anime verses. The first is Digimon Fusion Kai, which retells Dragon Ball Z under the Kai format with Digimon characters playing the roles of said characters. It is also a rewrite of his previous series back in 2001.
  • The Elemental Chess Trilogy is effectively this. With four novel-length installments, plus one collection of side stories and a fifth volume currently in production, it is known as one of the largest Fullmetal Alchemist fanworks.
  • The Pokemon fanfic Pokémon Reset Bloodlines has expanded with side stories by both the original and several other writers, covering a wide variety of characters with expanded backstory and lore in a new universe Ash Ketchum Peggy Sued himself into. The continuity as a whole has now been dubbed as the Resetverse.
  • The Tiesverse is a Fullmetal Alchemist (2003) AU where Edward gets involved with vampires and dhampirs while on the other side of the Gate.
  • Path Of Needles is a Sasuke/Sakura-centered fan verse based around Boruto. The main story revolves around Sakura becoming unexpectedly pregnant with a second child.
  • The Altered Destinies is a huge series of Alternate Universe Fic that look into alternative histories for the characters from Ranma ½. The reason it is so big is that it is actually made up of multiple Fan Verses including some in This Very Wiki. In fact due to its size even the author’s aren’t entirely sure which fanfics are a part of it. note 
  • The Shadowchasers Series is a collection of fanfics by several authors, set in an Alternate Universe of Yu-Gi-Oh!, where monsters of myth and legend - called Shadows - have always existed on Earth alongside humanity, only seen by a select few, with the titular Shadowchasers acting as a law enforcement organisation. Other than the fics centered around the Shadowchasers, there are also fics taking place in the same universe, such as the redux of Yu-Gi-Oh! The Thousand Year Door.

    Comic Books 
  • Batman has an epic series known as the Cat Tales universe which some people think of as better than some of the published stuff. It has lots of awesomeness for many characters, but the main thread is attempting to create a realistic romance between Batman and Catwoman without sacrificing any of their characters' awesomeness. This is mixed in with liberal amounts of drama, humor, believable character development, and tons of great action. The first story is A Girl's Gotta Protect Her Reputation. And best of all, the author is still going strong after 54 stories and nine years — the first chapter of the first story was published on March 8, 2001. With regular updates every few weeks, no less! Also has a fair number of sidestories in the same verse co-authored by others, fan-art and its own website, here
  • There is a fanfic version of the Marvel Universe that puts much more of an emphasis on lesser-known heroes and villains, such as the 1990s superhero Sleepwalker, rather than mainstays such as Spider-Man, the Fantastic Four or Captain America, who usually guest star in the C-listers' own stories rather than get the main spotlight. Many aspects are also heavily reimagined, such as Gwen Stacy being alive and well as Peter Parker's one true love, and Mary Jane Watson developing her own spider-powers as Spider-Woman, with her own rogues gallery and supporting cast entirely separate from Peter's.
  • There are several fanfics written by the same author using The DCU heroes set during the 1940s mixing elements of modern continuity with Golden Age tropes. Word of God says the basic impetus of this retro-style Fan Verse was an excuse to write a story where Superman actually gets to punch out Hitler.
  • On LiveJournal, the DC Universe RP of JLA Watchtower and its spinoff DC Nation has been going strong since 2004, using a combination of adapted DC Comics storylines and original plots. There have also been "flashback" posts that go into earlier parts of DC continuity.
  • The best-known Watchmen fan verse is a magnificent Zombie AU, of all things.
  • The Shadowchasers fan verse, started by the Fan Fiction great Black Panther, has spawned several continuing fanfics on
  • All Dark Mark's DC Universe fanfics are set in the same Multiverse kicked off by his first fanfiction "Kara of Rokyn". Hellsister Trilogy and Superman of 2499: The Great Confrontation, "Batman and the Outsiders", "With this Ring"... are set in the same timeline. A Force of Four is set in a parallel universe, but the main characters take part in the main timeline's events. Superman and Man happens after "Kara of Rokyn". Similarly, some of their Marvel Universe fanfics are set in the same universe.
  • DC Fan Universe is a huge subreddit reimagining several DC characters in one shared universe, with wickedly creative twists on each.

    Fan Works 
  • The "Fanfic Domain", created by's Crazyeight, is both Fan Verse and metafictional masterpiece. One of its central premises is that authors are bodily transported to the Fanfic Domain and meet characters face-to-face; canon events actually happened to the characters and they actually experience the fanfics into which they are written. Enter Fan Dumb, and with it, plot.
  • Possibly the largest Fan Verse is Eyrie Productions' Undocumented Features, with nearly twenty years of work and a coherent setting spanning at least 500 years of in-story time (and thousands of years of history), and incorporating dozens upon dozens of sources.
  • The Infinite Loops is a Massive Multiplayer Crossover by countless authors on Spacebattles Dot Com, where every work in existence is a branch of the supercomputer Yggdrasil, and because of the Crash all those branches are now trapped in a "Groundhog Day" Loop. There are specific guidelines that each loop must follow, interactions between settings, and even a masterlist that determines which snippets are canon or not.
  • Infinity Train: Blossomverse was originally a main trilogy of stories that was a crossover of Infinity Train and Pokémon: The Series before expanding on numerous variations and inspired other crossover fics.

    Film — Animation 
  • The original, darker concept for Zootopia, where prejudice against predators was so strong that preds were forced to wear shock collars, was popular enough with fans to inspire a host of fan works set in "Zoodystopia".
  • Becoming Free is a Frozen fic that has various spinoffs and more than one sequel. It's a series where Elsa falls for her new female horse farrier.

    Film — Live Action 

  • The DAYDverse, a darker take on Harry Potter started by Thanfiction and expanded upon, with the primary protagonist being Neville Longbottom. Starts with a parallel story to Harry Potter and the Deathly Hallows and continues with the second of three books called "Sluagh," as well as numerous one-shots, missing scenes, and character profiles.
  • The Dangerverse, also for Harry Potter. Started by whydoyouneedtoknow (and yes, that is a The Incredibles reference), the story reimagines the canon. At last count the mainline story was at 1.18 million words and counting. As with the Dumbledore's Armyverse, there are numerous one-shots, missing scenes, and numerous Alternate Universe fics by the author. At last count there were at least four alternate universes written by other authors.
  • Author bedlamsbard on LJ has three Narniaverses — Warsverse, Petaverse, and now possibly Casverse. Also Dustverse, which is really a continuation of Warsverse. Maybe.
  • The Les Misérables fanfic Paris Burning is the root of one of these. The author of the initial fic and various other fans have taken the premise (Hetalia-esque personifications of cities, with a rather darker tone) and run with it to create stories that, at this stage, bear little relation to the events of Les Misérables itself.
  • What Happened In Oregon and What Happened In Edmonton are set in the Oregonverse, a timeline inspired by the Steelheart novels. The main difference is the setting, with different parts of the world being explored and minor variations in how the mechanics of the Epic corruption works.
    • Vanilla Sabotage Bad End is a Fan Verse of the already existing Oregonverse, where several of the few human characters gain abilities. "Fan Verse" might be a stretch, considering it is primarily written by the original creators of the characters.

  • The Hamilton fanfic it feels more like a memory, written by savrenim, has two In-Universe musicals based on the fic’s events long after the fic’s events have become historical events In-Universe. One musical (also titled Hamilton) has a synopsis, the other (Burr: An American Musical) an incomplete script and audio files of some of its songs for people to peruse in real life. In-Universe, if there's a reason, is the fanfiction the In-Universe version of savrenim wrote after hearing Burr: An American Musical. Out of universe, it feels more like a memory has fanfic of its own.

    Theme Park Attractions 
  • The Haunted Mansion and the Hatbox Ghost is a fan verse created on DeviantArt by users Kelly-M-Mortal, Benthehyena and Scrooge Mac Duck. It focuses on the Haunted Mansion ride from the Disneyland parks, and includes short stories, a multi-chaptered fanfic, and various illustration and one-panel comics, all set in an unique Fan Verse of which the most important character is the Hatbox Ghost.


    Video Games 
  • Fritz Fraundorf's Massive Multiplayer Crossover comedy writings, borrowing from every Role-Playing Game he's ever played.
  • Eric "Erico" Lawson's Legacy of Metal consists of over a million words of Mega Man (Classic) and Mega Man X fanfic spanning nearly two centuries of history (2039-2222). Much of it expands on the plot points of Rockman: The Robot War in Broad Strokes as well. The author has posted a timeline and retrospective descriptions of each fic (scroll down).
  • All of the works within the Warcraft fandom by Weiila take place in the same universe.
  • Xanrivash on fanfiction has created a fan verse for Kingdom Hearts that gives the Organization members larger backstories and fleshed-out personalities.
  • Thanks to the fact that the canon characters are largely skeleton characters made of tropes specifically to give the fan fic writers more latitude, Touhou Project largely relies upon a collective subconscious understanding of what each character is, with each fan fic author slighly altering the character more in line with their own tastes (such as a violently self-centered Reimu to a just plain ambivalent Reimu), but relying upon the same tacitly agreed-upon traits. A few have proper names and are based on popular or highly-exposed fanwork; these include Walfas's math-joke-heavy Flash cartoons and the action/parody Advent Cirno. There is a minor, infamous (at least on Pooshlmer) 'verse called the 'Soak.
  • Fan verses are extremely common in Mass Effect fandom, to the point where most fanwriters have their own verse, usually revolving around their particular Shepard. See also the Cerberus Daily News forum where fan characters interact and RP with each other whilst still existing in the confines of the canon.
  • As the game Oolite is itself a Fan Remake of the classic Elite, its Expanded Universe is basically a Fan Verse for that game by proxy.
  • Immortality Protocol Cy Fox is a fanfic-verse derived from Sonic the Hedgehog which takes place exty years in the future in what is perceived to be our reality (minus the obvious creation of the Sonic games in the 1990s)
  • The Pokéumans series has been successful to build an entire community on the website with literally hundreds of members. They have admins, group contests, special events and even annual awards.
  • Final Fantasy RPG was a collaborative verse set in a world based on Final Fantasy I, IV and VI, and shared continuity with Nu RPG, a Massive Multiplayer Crossover verse set in a world based on Chrono Trigger.
  • Feynite of Dragon Age fandom has two fan verses based off of two large multi-chaptered stories, The Dread Wolf's Heart (complete) and Looking Glass (WIP). Definitely qualifies, with fanon, fanart and Recursive Fanfiction abundant on their Tumblr and Archive of Our Own account, and perhaps unsurprisingly, crossovers. Potentially widens to three fan verses with their modern-day Alternate Universe stories, or just one massive multiverse.
  • Dragons Unite is a saga of many stories and accompanying pictures, based on Spyro the Dragon but set on Earth and expanded way beyond the game's original lore, and occasionally intentionally contradicting is. It might as well be called Anthropomorphic Dragons On Earth - the 'Verse at this point.
  • The Skyhold Academy Yearbook series is growing into one of these, with multiple stories and even in-universe fanfic penned by two of the original characters in the series. Because it's a Bat Family Crossover for Dragon Age, it can't help being an enormous project, and the authors admit that even they aren't sure just how big of a verse it's going to ultimately be.
  • The Skyverse is a fan universe about an Alliance of Alternates of Sky, Boyfriend's Loony Fan, after the success of the Vs Sky mod, featured both in Friday Night Funkin' fan works (like Nusky Plus Skyverse and Sky Remanifested) and outside of them. It goes to the point to even have its own wiki.
  • Pokemon Light AU is a series of dark Pokémon Sword and Shield fics that begin after Gloria is Driven to Suicide.
  • In the Undertale fandom, the Fandom-Specific Plot of creating What If? Alternate Universes, such as Underswap and Underfell, has essentially been turned into one gigantic effort by countless creators to insert them all into one multiverse, with a number of Alternate Selves of the canon characters operating on a multiverse level. For example, Ink is the protector of all the AUs, CORE!Frisk can travel between all of them, Error wants them destroyed, and so on.
  • Star Trek Online:
    • The War of the Masters was a sprawling Shared Universe that developed on the official forums during what became known as "The Great Content Drought".note  Very much Darker and Edgier than the canon game, it posited Eldritch Abominations called the Good Masters as threats, along with political corruption in the Federation that led to a cluster of planets along the Klingon border declaring independence. Naturally it ended up very much Outdated by Canon once storyline development resumed.
    • Bait and Switch (STO) is a smaller 'verse of mostly short fiction written mainly by StarSwordC, with later contributions from worffan101 and takeshi6. It began to diverge quite strongly from the official storyline starting at the Iconian War, including among other things a story arc dealing with a resurgent Cardassian True Way insurgency that declared itself a new Cardassian Empire.

  • There are several fanfics by the same author with Terinu set in the period prior to the canon storyline, set just after the Varn Dominion's conquest of the Earth, one set in Vulpine Prime's past just prior to their conquest by the Dominion, and a notable crossover with the Season Five Stargate SG-1 team. At least a couple of fanfics by other authors have crossed over OC's, and a couple of bits of Fanon were incorporated into the main storyline by author Peta Hewitt.
  • The Homestuck fandom has a few. For instance, there's the TROLL!COPS AU, which puts the characters in a Cop Show-like modern setting. Or the Population series — where the twelve trolls settle down on Earth after the canon plot is over. The stories tell about how the trolls and their numerous progeny try to integrate themselves into Earth society, have wacky interpersonal hijinx, and lots and lots of sex.
  • Inonibird's Metal Gear Solid 3: Snake Eater universe from The Cobra Days became so popular that other fans started writing in the same universe. Some notable fics to come out of it include "Strange Wind" and Ryuichifox's art and writings about the Fear and the Fury.

  • Anthony Bault took up the reins of a (relatively) well-known Fan Verse called Arcadia. It's loosely based off the "Captain N: The Game Master" theory, that all the game universes (Sonic The Hedgehog, Super Mario, Legend of Zelda, he's even crammed in every single anime he's ever watched into an "Ani-Earth") are connected. His work can be found here.
    • Ani-Earth is a completely different story altogether - it was a series of stories by another author that started out as a simple crossover between Sonic the Hedgehog and Tenchi Muyo! and spiraled out of control there!
  • The Sanza Salazar trilogy, a series of Teen Titans fics branching off from the end of season four which explore the identity of the thief Red X, whose identity went unrevealed in the original series. The second fic of the trilogy is a Fix Fic in which Terra is revived under different circumstances than in the original series finale "Things Change", while the third re-envisions the fifth season that the trilogy itself disregards.
    • The Sanza Salazar series is now getting a fourth installment taking place shortly after the third and written by an entirely different author than the original trilogy.
    • The so-called LegendVerse, also in the Teen Titans fandom, has existed since the end of the first season and has been added to by more than half a dozen writers, though only the originator consistently contributes to it at this point.
  • Daria fanfic has expanded outwards into what's actually known as the ' Daria Expanded Universe ', with such fandom-created characters as Lynn Cullen, Jim Vitale, Pat Hackney VII, Richard Rawlings, Steve the security guard, Julia Carlyle, Michael Fulton, Alfred Phelps, Veronica Morgendorffer and Col. Kyle Armalin (and that's just a partial listing) of Daria Expanded Universe original characters freely interacting with the canon characters. (Daria fans know these folks as if they had been on the show itself.) On the fandom's Wiki, there's actually a listing for the ' Daria Multiverse ', and many of the original characters have Wiki entries and histories as fully fleshed-out as the canon characters.
  • An impressive collaborative series was written for the Gargoyles series. What was notable about this was it based its story arcs on Word of God information about the future of the cartoon series, had it not been canceled. It included three "seasons" for the main Gargoyles stories, but also branched out with Brooklyn's time travel stories, the adventures of King Arthur and the London clan, and the story of the Scotland clan before its destruction.
  • The Arthur Goes Fourth fan-verse. Yes, an Arthur fan verse. It has two spin-offs, each set in a different grade.
  • MASK has seperate fan verses active on, the M.A.S.K Legacy series co-authored by Darster and Lisa J which is packed with original characters and crossovers with G.I Joe, and a universe shared by authors Zarius and Miratete, which attempts to be a little closer in spirit to the original cartoon, whilst still finding room for more adult subject matter
  • Transformers: Animated has three prominent authors who influence each other and built their own Fan Verses by bouncing off their ideas. There are a ton of minor universes they write about, and they seem to have a blatant disregard for canon, so avoid if that doesn't work for you.
  • The Chip 'n Dale: Rescue Rangers fandom has a couple of its own, started as a continuous series of Fan Fic and often picked up by other authors than the original one. The first one was the series The Adventures Of Gadget Hackwrench which, after the success of the epic hallmark Rhyme and Reason, encouraged Rangerphiles to start writing and sort of launched the Ranger fandom's rich Fan Fic tradition. The most famous example, however, is The Nowakverse. Others are, for instance, Chip Noir Dale's Rescue Rangers or The Midnightverse.
  • In the early days of the Sonic the Hedgehog cartoons (specifically Sonic the Hedgehog (SatAM)), several Fandom VIPs, such as Bookshire Draftwood and Dan Drazen, did this. In fact, they did it in such a way that their own verses could theoretically fit into each other's with little difficulty. These Fan Verses got so large and popular that dozens of other writers over the years contributed with episodic stories that could also slip right in, culminating in a pretty massive web with hundreds of connected stories.
  • My Little Pony: Friendship Is Magic fan-verses:
  • The Piratesverse, a series of fics that serve as a continuation of The Pirates! In an Adventure with Scientists.
  • The Starlight Series, a series of fanfics crossing Lilo & Stitch: The Series with Star Trek and Cardcaptor Sakura.
  • Gravity Falls seems to be a magnet for fan-made alternate universes:
    • Reverse Falls AU, in which Gideon Gleeful and Pacifica Northwest are the heroes and Dipper and Mabel Pines are the villains (with Bill Cipher as their wimpy bound demon servant), with the overall tone being Darker and Edgier.
    • Transcendence AU, in which rather than the actual events of the show's finalenote , Dipper ends getting possessed as a last-ditch effort by a dying Bill Cipher. Although Dipper is able to fight Bill off and kill him, he fused with the leftovers and became a demon who goes by the name Alcor, albeit one with an unusually strong connection to the physical world and no upper cap on his power level. It also caused Gravity Falls' weirdness to spread out over the world in an event known as the Transcendence. Dipper's demonic upgrade makes him immortal, and he spends the next several million years trying to hold onto his humanity and watching over the descendants and reincarnations of his loved ones, until his suicide after the heat death of the universe. It's a bit unusual in that there's no central fic: rather, there's a blog whose mods are the authorities on what is or isn't canon for the verse (particularly Mod Z, or Zilleniose on Tumblr), but in general the verse's canon is pretty loose and open to contribution from anyone.
    • Monster Falls, in which the people of Gravity Falls are some way or another (usually by Bill Cipher's influence) turned into various monsters: Dipper is usually a deer-centaur or faun (also known as "Deerper"), Mabel is either a mermaid or a unicorn-centaur, Grunkle Stan is a gargoyle, Wendy is a werewolf, and so on.
    • Relativity Falls, an age-swap fan 'verse in which young Stanley and Stanford Pines spend the summer with their "Grauntie Mabel" investigating the weird goings-on in Gravity Falls with a teenage Manly Dan and handy-woman Maria Ramirez (Soos's grandmother). They later meet Dipper, who is the Author in this universe.
    • Sailorleo's Reunion Falls, in which Dipper and Mabel were Separated at Birth, and Mabel comes to Gravity Falls to meet her long-lost twin. Other notable features of this AU include an increased role for Grenda and Candy, and some Mabel x Pacifica shipping.
    • The Mystery Farm AU by lemonfordrizzleart stars Stanley and Stanford who run their family farm as it becomes the center of strange activities after a UFO is discovered in the area.
  • In the Star vs. the Forces of Evil fandom, the Ship-to-Ship Combat that sprung up in the aftermath of "Bon Bon the Birthday Clown" inspired the Ship War AU (AKA "Diaz Half-Siblings"), inspired by this fan comic where Star and Marco's Kid from the Future butts heads with Jackie and Marco's kid from an alternate future over which mother will be the one with whom their father ends up. Related to this is the Fandom-Specific Plot that said comic also inspired, which has Marco's future children from various timelines traveling back in time for a variety of reasons (though ship-to-ship combat naturally results, however briefly).
  • The Loud House managed to build one based around the popular (if incredibly controversial) Incest Yay Shipping fandom known as Sin Kids AU, which chronicle the adventures of Lincoln's children fathered with his sisters and/or the various other females in the series, as well as how both generations deal with the fallout of said children, over various fanarts and fanfictions by different authors.
  • The Powerpuff Girls Declassified Universe is a fan-verse of dark The Powerpuff Girls reimaginings starting with Project Powerpuff: Declassified.
  • After Steven Universe: Future ended with Steven leaving Beach City to travel the country, a popular crossover AU known as "Steven's Summer Job" had Steven end up in Gravity Falls, where he settles for a while (usually reluctantly, after his car gets wrecked by a local monster), and takes a part-time job at the Mystery Shack. Hilarity Ensues as he bonds with the Pines Family and is open about his Gem half even as Dipper remains an Agent Mulder around Steven.
  • The Heroverse is one of The Loud House where all of the Loud Siblings are superheroes and each story focuses on one of them in some adventure.
  • Another The Loud House example is the Neu House. Created by BRSstarJV, the story follows Lucas Mackenzie as he gets tangled up in the adventures of the Neu Family, a family of magical, supernatural, and scientific people beyond his wildest imagination! While originally using Lincoln as the protagonist, the AU underwent a reboot when RaishaGS, LibraryWizard, and Ch53transportheli joined the scene, demoting most of the Loud House characters to extras. As of 2021, the series has been on hiatus, but a webcomic is still planned.
