When The Verse
is shaped by multiple creators, writing independently, many different comic book titles are set in a collective continuity. This makes it easy to have a Cross Over
. In contrast, a single TV series with multiple writers is just the Verse with subcontractors. Likewise, when different continuities by the same author are tied together later by an Intercontinuity Crossover
, that's Canon Welding
The nature of the Shared Universe — multiple independent creators creating one continuity — can easily lead to a Continuity Snarl
if it lasts a long time and the different creators don't take care to keep things straight. If a Shared Universe starts relying too heavily on continuity, especially if it's obscure or too reliant on each work in the Verse, a Continuity Lock-Out
may occur. When creators disagree on the direction the Verse should take, they may fight Armed With Canon
. If some corners of the continuity are "off limits" to some characters to avoid theme-drift or plot derailing, then Superman Stays Out of Gotham
When they go back centuries
, and even further
, long before copyrights and trademarks, the Shared Universe turns into one or more actual mythologies. Compare with The Verse
, Expanded Universe
. Contrast with Shout Out
Note: just because two or more works have had a Cross Over does not mean that they share a universe.

Anime and Manga
- Various universes of Marvel Comics.
- Similar to Marvel, The DCU is an examples of this, with multiple monthly titles who might not even have the same creative team month to month.
- And those two are connected by the Amalgam universe, several canonical crossovers and a few characters who break the fourth wall.
- Ninja High School and Gold Digger loosely share a universe and occasionally engage in crossovers or use each other's villains.
- In the Savage Dragon, there is a shared universe that not only consists of the rest of the Image Universe but also creator-owned properties such as Hellboy, Madman, and Bone have made appearances. Aside from that, Erik Larsen likes to slip in characters from the Marvel Universe and DC Universe. Often, this consists of characters showing up far in the background, being mention in passing but not shown, or having a single boot or glove visible that indicates that those characters are there but enough is concealed to avoid copyright issues.
- Virtually all of the early Image Comics titles were set in the same universe, with the stars of any given book often making guest appearances in another. However, one of the core ideas of the company was and always has been creator ownership. This caused a Continuity Snarl no less than twice; Once, when Rob Liefeld picked up his characters and left to create Awesome Comics (though he returned after Awesome folded), and again when Jim Lee took his properties, which encompassed about half a dozen titles, and made his Wildstorm Studios into a DC imprint.
- Currently, Invincible shoulders a lot of weight when it comes to establishing a larger Image universe. Characters from Kirkman's other books popping up frequently, and big events (like the funeral of the Guardians of the Globe or the Invincible War) feature just about anyone who's anyone in the company at the time. At one point Mark was even a member of the Pact, a team consisting of him, Zephyr Noble, Firebreather, and Shadow Hawk.
- Judge Dredd and its spinoffs share a universe with Strontium Dog, Rogue Trooper, Harlem Heroes and their respective spinoffs. Earlier stories also suggested that Invasion!, ABC Warriors, Ro-Busters and Flesh were part of this universe, but these have subsequently been retconned out.
- The My Little Pony: Friendship is Magic stories Rainbow In The Dark and Racer And The Geek have small nods, links and references. Both authors have implied that their stories exist in the same universe, although perhaps not in the same continuity. This is still completely nebulous.
- Dangerverse fans have written numerous fics of their own set in the same universe, many of which have been integrated into the canon, as well as Alternate Universe Fic aplenty. The author has no qualms about working in ideas from her friends and fans.
- The AU Shadowverse stories about Magical Girl Lyrical Nanoha characters Lutecia and Vivio, created by Radiant Beam, also involve many other writers who write about secondary characters in that universe. Each of the various authors tend to write around different themes (spy-thriller, emotional drama, political-thriller, etc) despite writing in the same AU.
- More than a decade after the release of Under The Bridge, Chip 'n Dale Rescue Rangers fan fiction writers love to include enough elements from The Nowakverse into stories of their own, especially the main original characters.
- The Lunaverse is a My Little Pony: Friendship is Magic AU where Celestia became evil instead of Luna. It started with one story by RainbowDoubleDash who promptly opened it up to anyone else who wants to write in it. Multiple writers took him up on this offer.
- Lunaverse alum GrassAndClouds2 is now running a Shared Universe of his own, The Cadanceverse. It is music themed, and features Cadance as the princess (after both Celestia and Luna were corrupted), Octavia as her student, and Vinyl, Fluttershy, Lyra, and two background ponies as the other Element Bearers.
- Most fanfictions writers seem to incorporate Ranma ½, InuYasha, and other works by Rumiko Takahashi in the same universe.
- Harry Potter fanfiction often has cameos from Wizards of Waverly Place and Hellsing, due to the similar premises of the first and the second occurring in England as well. Crossovers with Percy Jackson are also not uncommon.
- Naruto and Bleach X over so much that it is very common to see OC ninja share their names instinctively.
- The bulk of the Pony POV Series is written by the same guy and his editors, but quite a bit of the Recursive Fanfiction has been declared officially canon (or at least Loose Canon) by said author.
- Like the Lunaverse, Life In Manehattan (aka the Manehattanverse) is an AU of My Little Pony: Friendship is Magic, this one based on the premise that the Elements of Harmony were found some time before the pilot and taken to a museum in Manehattan; therefore, it's there that Twilight Sparkle goes for the Summer Sun Celebration, makes friends, and ends up living. The first story by the original author covers the alternate events of the pilot, after which other authors have started writing their own tales of the Manehattan 6.
- Many of the animated works of Pixar seem to fall into this category, mainly because of the countless references in their films and shorts that overlap with each other. The Pizza Planet Truck from Toy Story is the best example of this, which has showed up in nearly every feature film of theirs.
- Because Marvel Films holds the rights to all Marvel Comics characters not given to other studios (Spider-Man, X-Men, Fantastic Four, Men in Black and Kick-Ass), they have managed to bridge together a single continuity family with links between the characters' stories. Nick Fury makes a cameo in Iron Man referring Tony Stark to the "Avenger Initiative," Tony appears in the film of The Incredible Hulk talking to General Ross about putting a team together (also having a nod to Captain America: The First Avenger), Iron Man II gave many hints to Thor, and the whole thing came together in The Avengers as a Crisis Crossover. This cycle is planned to be repeated, starting with Iron Man 3 in 2013 and building up to to an Avengers sequel in 2015.
- Note that this universe does not (yet) extend to Marvel characters such as Blade, Daredevil, Ghost Rider and The Punisher who were under license to other studios but whose film rights have now returned to Marvel.
- Supergirl takes place in the same continuity as the Christoper Reeve films. (Jimmy Olsen appears in the film for example.)
- Pulp Fiction and Reservoir Dogs, both Tarantino films, share a link in that Vincent and Mr. Blonde are apparently brothers, although it's not immediately obvious from watching the films.
- Originally the connection was intended to be much stronger. In early drafts of the script, the briefcase Vincent and Jules retrieve contain the diamonds stolen in Reservoir Dogs
- Additionally, Lee Donowitz from True Romance is the son of Sgt. Donny Donowitz from Inglorious Basterds. Furthermore, Alabama from True Romance is the same Alabama that Mr. White mentions in Reservoir Dogs. Meaning all four movies are in the same universe.
- Machete and Spy Kids share the same universe as confirmed by Word Of God, one must wonder which came first in terms of timeline, the misadventures of Uncle Machete or the Spy Kids?
- The Cthulhu Mythos is a famous and early example of this; professional fanfiction set in his world is not only published, but was also acknowledged and supported by Lovecraft before his death.
- The Wild Cards Super Hero books were designed as Shared Universe Anthologies from the ground up.
- Bordertown is a city between the "real world" and Faerie. It was originally created by Terri Windling, but Emma Bull, Will Shetterly, Charles de Lint and several other writers have written stories set there.
- 1632 was originally to be a one-off novel, but due to favorable fan response went beyond that, later expanding into The Grantville Gazette, one of whose main goals is to give previously unknown authors a way to be published, and paid for their work at professional rates instead of less generous fanzine ones. Unlike with many anthologies, the contributions from other authors affect the "main" story line works. There are very few aspects that are truly forbidden to these authors, primarily those where it would interfere with the prerogatives of Eric Flint, the series creator.
- Thieves' World was a dark fantasy Shared Universe created by Robert Asprin in the late 1970s. It had contributors like Poul Anderson, John Brunner and Marion Zimmer Bradley and generated 12 anthlogies of short stories, seven official novels and a bunch of roleplaying adaptations before writing stopped in 1989, with a short revival in the early 2000's. It preemptively dealt with Continuity Snarl with a preface framing story about an old timer talking to a new arrival in the city about how one should not believe everything in the stories one hears, as everyone spins the stories to fit their agendas, to make themselves sound more important in a good story, or less to blame in a bad one, and two people telling the same story may have wildly different variations.
- The universe of the Bolo super-tanks, originally by Keith Laumer, has been shared by everyone from John Ringo to Mercedes Lackey.
- The Russian Death Zone series is worked on by several known Russian sci-fi authors and is loosely based on the Stalker games. Unfortunately, this tends to create certain lapses in continuity. For example, in Andrei Livadny's novels, the Order is portrayed as a rational group that believes in the existence of an otherdimentional point known as the Node based purely on empirical evidence. In Roman Glushkov's books, they are fanatics spouting religious nonsense about the Holy Node before sacrificing themselves for the cause. It could be explained that these are different members of the Order interpreting their teachings, if they were not using the same characters.
- Other major differences involve the very nature of the Zones. For example, in Livadny's novels, there is no plant or animal life in the Zones, as anything exposed to the scorgs gets "upgraded" (i.e. it becomes a weird mix of flesh and metal bearing little resemblance to the original). Rust by Aleksey Kalugin shows the Moscow Zone full of plant and, occasionally, animal life with only a few examples of bio-tech mixes. Kalugin's nanobots (the word "scorgs" is never mentioned) only care about consuming metal and reanimating machines.
- The Liavek anthology series- stories by several different authors, set in and around the city of Liavek. Apparently the setting started out as a RPG invented by Will Shetterly for his writer's group, The Scribblies; they later fleshed out the setting and produced five volumes of short stories (and a few poems). Two of the authors, John M. Ford and Pamela Dean, later wrote more stories in the same universe.
- The Midnight Rose collective, a group of British SF writers, published several shared-universe anthologies in the early 1990s, with settings including Temps (tongue-in-cheek superhero stories) and The Weerde (shape-shifting aliens are the source of all the world's myths and conspiracies). Contributors included Stephen Baxter, Neil Gaiman, Mary Gentle, David Langford, Kim Newman, and Charles Stross.
- Merovingen Nights was an anthology series set on the planet Merovingen, in an islolated corner of C. J. Cherryh's Alliance/Union universe.
- Heroes in Hell was an anthology series with a concept similar to Riverworld: all the dead wind up together in Hell, where they pick up where they left off when still alive.
- The universe of the Malazan Book of the Fallen was jointly created by Steven Erikson and Ian Cameron Esselmont, and both authors have written their own novels for the setting.
- The '80s Magic in Ithkar anthologies were more of a shared setting; all the stories started with the setting of Ithkar Fair, detailed in the anthology prologues, but other than that each author's stories were free-standing, sharing no characters, events, or settings beyond those established in the prologues. Most notably, one story ended with the Fair being shut down due to plague; this was not reflected in any of the others.
- The Spore Wiki Fiction Universe began life as a Spore fan fiction continuity but eventually separated itself. It's shared between multiple writers and is open to anyone willing to write for it.
- Galactic Crucibles, which also originated as Spore fan fiction, is a shared Space Opera universe between numerous authors with a large focus on worldbuilding. Interestingly enough, it is implied to be part of the same multiverse as the Spore Wiki Fiction Universe.
- As well as the Infernal Devices prequel series, The Mortal Instruments to be set in the same universe as the Modern Tales of Faerie by Holly Black. Val and Luis from Valiant are the homeless kids Clary sees in the first book and Simon listens to Stepping Razor, Ellen's band from Tithe.
- Ironside references the Mortal Cup.
Live Action TV
- Warehouse 13 and Eureka share a universe with Alphas.
- CSI: Crime Scene Investigation, CSI: NY, CSI: Miami, Cold Case and Without a Trace are all in the same universe.
- After a great many hints in the various Dan Schneider shows, I Carly canonized that it exists in the same universe as Drake & Josh, Zoey 101, Victorious and now Sam & Cat.
- The DCLAU, the Disney Channel Live Action Universe, which is comprised of Even Stevens, That's So Raven, The Suite Life of Zack and Cody/On Deck, Hannah Montana, Cory in the House, Wizards of Waverly Place, Zeke and Luther, I'm In The Band, Good Luck Charlie, Pair Of Kings, Shake It Up, Kickin' It, A.N.T. Farm, Jessie and Austin & Ally.
- Every show within the jurisdiction of Miller-Boyett Productions. The most obvious examples are Family Matters, Full House, Boy Meets World, and Step by Step, all of which have characters who know Steve Urkel.
- The various seasons of Power Rangers are shown to exist in the same Universe. This was most obvious in the early years of the series, which had one, continuing storyline culminating in Power Rangers in Space. Later seasons tend to downplay this, but the various crossovers and reappearing characters establish that the universe is the same. However, Power Rangers RPM takes place in an Alternate Universe, something not made obvious until its crossover with Power Rangers Samurai.
- JAG, First Monday, NCIS, NCIS: Los Angeles and the new Hawaii Five-O are a shared world, as evidenced by Kensi's presence in Hawaii.
- The Kamen Rider series, specifically the Showa Era all exists in the same universe as evidenced by the presence of this common enemy called "The Great Leader". Later on in the old Heisei era, Kamen Rider Kuuga and Kamen Rider Agito shared the same universe. And then in the new Heisei Era, Kamen Rider Double, Kamen Rider OOO, and Kamen Rider Fourze exists in their own Shared Universe for their Big Bads are all linked by the Nebulous Evil Organization "Foundation X" (the new generation's equivalent of Shocker, it would seem).
- Kamen Rider Fourze pretty much confirms that all Kamen Rider series are in the same universe.
- All the Law & Order series share a world with Homicide: Life on the Street, due to John Munch.
- The Filmways-produced Petticoat Junction and Green Acres were both set in the town of Hooterville, and characters from each gravitated to the other fairly regularly.
- "The Girls Of Hollywood High," the second of two Poorly Disguised Pilots (for a proposed series about Texan private detectives called Eyes Of Texas) which aired as BJ And The Bear episodes, established that this shares a universe with another Glen A. Larson series - at one point the female PIs pay a visit to the Los Angeles Coroner's Office. John S. Ragin and Robert Ito turn up as the characters they play on that particular series, but Jack Klugman, alias Quincy, is conspicuously (and given how he felt about Glen Larson understandably) absent.
- Most of the series produced by Jack Webb take place in the same universe, including Dragnet, Adam-12, Emergency! and the short-lived Robert Conrad vehicle, The D.A.
- Magnum, P.I. had two crossover stories that concluded on Simon And Simon and Murder, She Wrote.
- Simon & Simon also had meetings with Whiz Kids.
- Murder, She Wrote also shares a universe with an obscure 1949 film-noir called Strange Bargain; 40 years after the movie, Jessica Fletcher helped uncover the real killer from the original movie.
- Diff'rent Strokes, The Facts of Life and Hello, Larry.
- Diagnosis: Murder shares a universe with Matlock (Matlock defended Dr. Jesse Travis in a murder case), Mannix and Mission: Impossible (due to an appearance by Barbara Bain as Cinnamon Carter).
- Barnaby Jones shares a universe with Cannon, as shown in the former's pilot episode (Cannon is friends with Barnaby's soon-to-be-murdered son).
- Older Than Steam: Perhaps the oldest non-mythology example is the Jianghu (literally "rivers and lakes") fantasy world in which most Chinese wuxia books, films, TV series, etc. are set. Jianghu dates at least to the 14th-century novel Water Margin.
- Each Dungeons & Dragons campaign setting is its own 'Verse (See the page on D&D for more information), and the associated novels have many different authors, though - like the Star Wars Expanded Universe - the writers usually have to clear their ideas through the universe's owner.
- Dungeons and Dragons also has all of the settings linked in Planescape and Spelljammer, but those are rarely mentioned as existing except for their own continuities.
- Given that Urban Arcana is our Earth, only with hidden fantasy elements, the Earth that Forgotten Realms canonically is connected tonote is probably that Earth. Planescape, at least, has a connection to Urban Arcana via a shared character that namedrops Sigil and has a way to traverse the Shadow that otherwise acts as a boundary between Urban Arcana and the rest of the multiverse.
- The Warhammer 40,000 universe is shared by a large number of writers; the sheer scale of the setting in both space and time helps avoid continuity problems.
- In early versions of the background, it was heavily hinted that the Warhammer Fantasy world was part of a planet cut off from the rest of the universe by warp storms, explaining the many shared elements. However, mentioning this nowadays is liable to get you bundled into a van and never seen again.
- Word Of God places Doctor Horribles Sing Along Blog, The Tick and the Venture Brothers in the same universe.
- Spells R Us was started off with Bill Hart's story A Strangeness at the Frat House and then became not so much a universe but a single series of the same character in the same errant shop all ending up with customers being transformed into something.
- The Transformers Aligned Universe encompasses Transformers: Exodus (and Exiles), Transformers Prime, Transformers Rescue Bots), Transformers: War for Cybertron (and Fall Of Cybertron), and Transformers Universe.
- Grand Theft Auto and Manhunt (both developed by Rockstar Games) take place within the same universe, as confirmed by overlapping references like placenames, vehicles and fictional brands. Rockstar's Bully is also a possibility though there are not enough references that verify this.
- Portal shares a universe with Half-Life.
- The Super Mario and Donkey Kong series exist in the same universe, as shown through Donkey Kong, Diddy, Dixie, and Funky appearing in Mario spin-offs, as well as Mario and Yoshi appearing in Donkey Kong Country 2. Additionally, due to first appearing in Super Mario World and Super Mario Land 2 respectively, the Yoshi, Wario Land, and WarioWare series are also part of the expanded Super Mario Universe. The entire Shared Universe of Mario, however, is much, MUCH larger.
- Street Fighter, Final Fight, Saturday Night Slam Masters and Captain Commando take place in the same universe. Rival Schools and Darkstalkers may also be part of it.
- A few Final Fight characters (namely Guy, Sodom, Rolento, and Cody) have appeared as fighters in the Street Fighter Alpha series, with stages and endings featuring cameos by other characters. Andore appears in Street Fighter III under the name of "Hugo" with Poison acting as his manager. Both, Guy and Cody returned in Super Street Fighter IV. Additionally, Chun-Li makes a cameo in Stage 1 of Final Fight 2 and the portable versions of Alpha 3 features Maki as an extra character.
- Haggar appeared in Slam Masters as a wrestler. The U.S. localization refers to him as the "former mayor of Metro City", although the original Japanese storyline actually places the games before Haggar was elected. A couple of Street Fighter characters have cameos in the Slam Masters series (such as Chun-Li, Honda, and Balrog) and the Slam Masters are referenced in Hugo's ending in 2nd Impact.
- Captain Commando takes place in a futuristic version of Metro City. A sculpt of Mike Haggar is featured in the game as an bonus item, and Ginzu the Ninja is a future successor of Guy in the Bushin style of Ninjutsu.
- The first Rival Schools features Sakura as a playable character (although, her blood type is different from the one given in the Alpha series). Moreover, the Nekketsu Seisyun Nikki spin-offs has Hinata studying the "Ken Masters style of Karate" and Iinchou/Chairperson learning "Saikyou-Style" through mail. On the other hand, there are a few date discrepancies according to the first game's intro and Sakura's storyline (in which she's yet to meet Ryu, placing the series pre-Street Fighter Alpha 3).
- In Night Warriors: Darkstalkers Revenge, Felicia claims she wants Blanka as the leading man in her new movie. Among various Capcom characters, Morrigan, Felicia, Hsien-Ko, Mei-Ling, and Lord Raptor can be seen on Ken's stage◊ in Street Fighter Alpha 2, although there's a distinct possibility these are very convincing cosplayers.
- While not part of the main Street Fighter continuity, the Arika-developed Street Fighter EX games shares a couple of characters (Allen and Blair) with their independently developed arcade game Fighting Layer.
- There's a few blink-and-you'll-miss-it examples from other Capcom series. In Dino Crisis, one can spot the Umbrella Corporation logo on several boxes found in-game. The game's setting, the Borginian Republic, is reused as a location in the Ace Attorney series (called the Republic of Borginia there). Furthermore, the dog that you can rescue from a bear trap early on in Resident Evil 4 is none other than Hewie from sister Survival Horror game Haunting Ground.
- Koei's Warriors Orochi was made to confirm that its series Dynasty Warriors and Samurai Warriors take place in the same universe but the second trailer of Warriors Orochi 3 more or less confirms Koei's other games Warriors Legends Of Troy and Blade Storm The Hundred Years War due to the presence of Achilles and Jeanne D'Arc. It also confirms that its business partner Tecmo's series Ninja Gaiden and Dead or Alive take place there due to the presence of Ryu Hayabusa and Ayane. By extension it might also existin the same universe as Halo due to the Spartan Nicole's presence in Dead or Alive 4.
- And to the Metroid series via Samus and Ridley's appearances in Dead or Alive: Dimensions.
- The Ultima series features references to the Wing Commander series. In Ultima I there were spaceships that in Ultima VII: The Black Gate was explained to be the spaceship of the Kilrathi. As pointed out by Spoony here.
- Dig Dug, Baraduke (or Alien Sector if you prefer), and Mr. Driller are set in the same world, by virtue of Taizo Hori and Toby "Kissy" Masuyo being the parents of Susumu, Ataru, and Taiyo Hori (the first of the three being The Hero of the Mr. Driller series) and the events of the first Dig Dug being referenced directly in Mr. Driller (the "Dig Dug incident").
- EVE Online and the upcoming FPS DUST 514 are part of the same universe... literally. Players will be able to accept contracts and do missions for the player-run companies of EVE Online, and even form their own corporations that EVE Online players will be able to join.
- The Dead or Alive and Ninja Gaiden series both take place in the same universe, complete with having characters originating in one becoming plot-integral in the other. Of course, characters will change looks to match the art style of the respective games.
- The presence of both Seath the Scaleless and Patches the Hyena seem to indicate that Dark Souls shares the same world and universe as the Kings Field series and Demons Souls.
- Brøderbund Software tried to work the Bungeling Empire into most of its early 1980s action games. Choplifter and Lode Runner had it All There in the Manual; Raid on Bungeling Bay had it in the title but wasn't really a sequel to anything.
- Space Harrier is set in the Fantasy Zone; several Fantasy Zone games reference it to various degrees. The culmination of this was the unreleased crossover game Space Fantasy Zone.
- Marathon takes place in the same universe as Pathways Into Darkness, and possibly Halo. There is even a terminal in the first Marathon game (which is a historical record) that talks about the events of Pathways.
- The entire premise of the Reality On The Norm project. It is a shared universe set around the eponymous City of Adventure.
- The Tom Clancy series games (Splinter Cell, Ghost Recon, and HAWX) share a single universe, and often have crossover cameos with each other (this is particularly evident between Ghost Recon and HAWX).
- This easter egg from Assassin's Creed IV: Black Flag heavily suggests that Assassin's Creed and Watch_Dogs share a universe. Considering that AC 4's MacGuffin would be of tremendous use in Watch_Dogs, this is unsurprising.
- Video Game/Touhou, Seihou, and Uwabami Breakers take place in the same universe, with the first being the only place that retains magic in the 'verse. If a certain ending is any indication, it also shares universe with To Heart.
- Webcomics tend to be chock full of Crossovers and Shout Outs, but very few non-Spin-Off comics have Shared Universes. Among those that do:
- Badly Drawn Kitties and Better Days and Sabrina the Skunk all crossed over via the characters Lucy Koneko and Zig Zag, although various author dramas try to retcon this out of existence
- Something Positive and...
- Melonpool and the Walkyverse
- In fact, all of the above apparently share a universe now, since characters from Something Positive and Girls with Slingshots have appeared in Shortpacked!.
- Questionable Content as well, though mainly as the odd cameo (and an implied spacewarp between the Shortpacked store and Coffee of Doom, which is actually pretty reasonable by QC standards at least - it's since been established that the coffeshop near Shortpacked which has the same layout, staff, clientele and espresso dinosaur as Coffee of Doom is called Coffeeright Theft).
- Questionable Content also shows Kim Ross, cybernetic protagonist of Dresden Codak, laughing at Pintsize's mishaps in an IRC.
- The pre-reboot version of Zortic was also part of the Melonpool-verse. Ralph and Splink were officially half-brothers. This hasn't been mentioned since the reboot.
- Melonpool, Ralph, Splink, and Zortic have all appeared in The Inexplicable Adventures of Bob! Aparently Voluptua knows Ralph and Splink's family.
- Neko The Kitty and Catharsis not only share a universe, they share an apartment building.
- The Wotch and The Accidental Centaurs
- Ryan North believes that his Dinosaur Comics and Andrew Hussie's Homestuck share a universe.
- The International Comic Continuity was created specifically to make a Shared Universe.
- Eerie Cuties/Magick Chicks and Vampire Cheerleaders/Paranormal Mystery Squad take place in the same universe, as evidenced by Steph and Layla's bonded hairpins and Word Of God. However, the Delacroixes and Lori's coven are different breeds of vampire following slightly different rules, and Charlotte is a very different kind of witch than Mel's coven, who for as-yet-unexplained reasons are considered cryptids while Charlotte (like the Artemis Academy's magical cadets and espers) is human.
- By definition, roleplaying boards such as Survival of the Fittest are Shared Universes, since each handler has his own spin on the story.
- The Whateley Universe. Right now, there are about a dozen authors writing about twice that many main characters. And that doesn't count the Fan Fic.
- Many Internet writing circles take the form of shared universes. Some such universes have been around continuously since the mid-1980s.
- The Randomverse contains multiple roleplays run by different people. They include The Death Series, The Insane Quest, Smile For The Camera and TV Tropes The Adventure.
- Jason Bortz, M. S. Patterson, and Christopher Wright share a universe informally titled "The Foldspace Universe." It's the setting for Pay Me, Bug!, among others.
- "In My World" and "Inspector Dan Rather" seem to take place in the same over-the-top-ridiculous universe, although they are told from very different points of view and rarely overlap. The only "Inspector Dan Rather" story not told from Rather's delusional point-of-view seems to confirm this.
- Several "imprints" on the superhero fiction newsgroup rec.arts.comics.creative, notably the Legion of Net.Heroes and Academy Of Super Heroes.
- The Metaverse is a slowly developing example, due to being comprised of live action videos, mostly made on a zero dollar budget.
- Rugrats, The Wild Thornberrys, and Rocket Power.
- Family Guy and The Cleveland Show, along with American Dad!.
- A subtle link exists among four of Marvel and Sunbow's Merchandise-Driven 1980s cartoons — the character of Hector Ramirez, a thinly veiled parody of Geraldo Rivera, appears in Inhumanoids, G.I. Joe, Transformers Generation 1 and Jem, though this has not been confirmed.
- In Transformers Animated: The All Spark Almanac II, Vector Prime confirms that all these shows and C.O.P.S. take place in the Transformers generation 1 continuity.
- Since the Looney Tunes characters are the teachers to the Tiny Toon Adventures characters, this makes an obvious example. A not-so-obvious addenum to this is that the Looney Tunes characters also made several cameos on Animaniacs and Histeria, which therefore means they too share the same universe. Additionally, the Animaniacs characters made cameos on Freakazoid!! (and vice versa) so this also makes this part of the WB Animated Universe (as it has been nicknamed).
- And since Pinky and the Brain also happen to share the same universe as the above shows, they're counted as part of it as well.
- While it's pretty obvious that DuckTales and Darkwing Duck share the same universe due to sharing one of the main characters, The Legend Of The Chaos God storyline in Disney Adventures also placed TaleSpin, Chip 'n Dale Rescue Rangers and Goof Troop in it as well.
- The DCAU.
- The Cartoon Network universe was first established with "The Grim Adventures of the KND". It consists of:
- Word Of God confirms that Transformers: Prime and Transformers: Rescue Bots take place in the same universe. This was finally confirmed in-universe by the Rescue Bots episode "Bumblebee To The Rescue". It's also the reason Rescue Bots is set on an island and Prime is set in the American midwest. This allows the two shows to reference eachother and interact while still being seperate.
- Fairly OddParents seems to share a reality with Danny Phantom because in a first season episode of the latter, Tucker and Danny are standing in front of a Crash Nebula video game. Crash Nebula is an in universe comic book character that originated in Fairly OddParents.
