Canon Welding: Difference between revisions

Line 2:

{{quote|''"They were independent, separate stories. But now...the stories are combining, that's why the worlds are becoming one."''|'''[[Kamen Rider Kiva|Wataru Kurenai]]''', ''[[Kamen Rider Decade]]''}}

When an author or creator takes two previously unrelated works and puts them into a single, shared [[Continuity]].

No, it's not about literally welding two weapons together to make a double barrel cannon. Although that would be [[More Dakka|awesome.]]

Line 10:

''Combine them!''

Many long-lived genre authors tend to resort to [[Canon Welding]], usually at a later point in their career. They combine two or more distinct series they've created into a single [[Continuity]]. This isn't just a one-off [[Crossover]]; for series with radically different premises, the foundations of one or both stories can be altered forever.

By combining the two series together, the author can introduce fans of one series to characters they may not be familiar with, inducing them to go out and buy the works in that series, and hopefully attract high sales from fans of both storylines. When done well, it can add a more epic feel to the tale, explore aspects of the two storylines not previously delved into, and make lots of money for the author and his publisher (and there are many examples of this, perhaps most famously ''[[Lord of the Rings]]''). When done poorly, especially with stories with radically different settings or styles, it looks and feels like a shallow money-grab and can potentially be a [[Jump the Shark|shark-jumping]] moment for both series.

Line 32:

*** It's gotten to the point that, near as anyone can tell of the yet-unreleased ''[[Kamen Rider x Super Sentai: The Great Superhero War|Kamen Rider X Super Sentai Super Hero Taisen]]'' movie, nobody except MAYBE Marvelous and Decade know what the hell is going on. Even the narrator is baffled.

* There have been countless ''[[Transformers]]''/''[[G.I. Joe]]'' [[Crossover]] comics and, even worse, the ''[[Transformers]]'' comic character [[Death's Head]], who was then involuntarily sent to the ''[[Doctor Who]]'' universe (in the comics only) and then the [[Marvel Universe]], bringing things full circle...except that ''Who'' [[Crossover|crossed over]] with not just ''Blake's Seven'' as mentioned above, but also [[Sherlock Holmes]] '''and''' the [[Cthulhu Mythos]] in the [[Virgin New Adventures|Doctor Who New Adventures]] novel ''All-Consuming Fire'' and...'''[[Public Domain Character|for the sake of Primus, we better stop at Holmes and the Mythos or else this dysfunctional multiverse will be too big for this page...]]'''in fact, given that ''Doctor Who'' is also part of Westphall's mind, and that Holmes is a member of the Wold Newton Family, what we've got here is a truly dysfunctional mess of a [[Multiverse]], lest we forget that there is also existence of what is most likely a [http://img.photobucket.com/albums/v283/factorialinfinity/prlggallifrey.jpg Post-Time War Gallifrey] in the [[Power Rangers]] Universe.

** That's not even bringing the fact that since [[Marvel]] has a huge [[Multiverse]] there's every universe in that they can [[Crossover]] with and therefor due to [[Marvel Zombies]] [[Evil Dead|Ash]] [[Army of Darkness|Williams]] could very logically have a meeting with the Doctor if they slipped through into the other's universe. This means that we could logically have Ash accidentally awaken Deadites in multiple time periods and have the Doctor (10, in an ideal world) and Ash work together to stop them in all of them. SOMEBODY WRITE THIS AS A [[Fanfic]] STAT!

** The main [[Marvel Universe]] itself still treats their comic book versions of ''[[Godzilla (film)|Godzilla]]'',''[[The Space Odyssey Series|2001: A Space Odyssey]]'' , ''[[ROM]]'', [[Conan the Barbarian]], [[Solomon Kane]], King Kull, [[Fu Manchu]], [[Doc Savage]], Shogun Warriors, ''[[Micronauts]]'', [[The Elric Saga]], and [[Red Sonja]] as canon even if they can't reference them by name.

** With the Doctor's cameo in ''[[Buffy the Vampire Slayer]]'' the ''Doctor Who'' episode where the Devil is trapped on an alien planet is starting to make sense. But that's not all considering how the ''[[Angel]]'' villain Illyria crossed over with [[Peter David]]'s comic [[Fallen Angel]] that heavily implies that the man character is [[Supergirl]] from [[Peter David]]'s run on the book. He even stated in an interview that the character Lee is Supergirl.

*** And with Compati Hero Series ''The Great Battle IV'' this would tie in both ''[[Gundam]]'', [[Ultra Series]],and ''[[Kamen Rider]]'', et al. with the aforementioned ''[[Super Robot Wars]]'' and...well. Just let your imagination go wild, one supposes.

Line 43:

** Due to Lars Alexandersson, ''[[Naruto]]'' is somehow connected to Soul Calibur.

** And with [[God of War|Kratos]] we can add the [[Mortal Kombat]], [[DC Universe]], and [[Nightmare On Elm Street]] to this expanding mess of a universe.

*** Also the franchises from [[Project X Zone]] and Playstation are tied into the Soul Series due to (guess who) Kratos showing up in Playstation All-Star Battle Royale and Project X Zone of course having Capcom which had already crossed over with Tekken as mentioned below.

* Virtually everything in Dozerfleet Comics will eventually end up in either the [[Ciem Webcomic Series|Gerosha universe]] or the [[Stationery Voyagers|Voyager universe]], usually the former. That means that [[Half-Human Hybrid|Candi Levens]] [[Fantasy Kitchen Sink|shares a universe]] with [[Chaotic Good|Navyrope]], [[Emotion Eater|Extirpon]], [[Determined Widow|Jessie]] [[Take Up My Sword|Morcin]] of ''Kozerlen'', [[Masked Rider|Prince]] [[The Frog Prince|Volkonir]] [[In the Name of the Moon|the Cortatian]], and [[Backup Twin|Aaron Stefflin]] of ''[http://dozerfleetwiki2.wiki-site.com/index.php/Blood_Over_Water Blood Over Water]''. And even [[The Ring|Mr. Each-Frame-Is-A-Week]] himself [[Eldritch Abomination|Marzwhatti the Lirquinwir]].

** That's not even counting [[Wicked Witch|Meshaluta]] from ''[http://dozerfleetwiki2.wiki-site.com/index.php/90_Has_No_Secant 90 Has No Secant]''.

Line 60:

*** Except for (presumably) Rudy Foggia of ''The Jaunt'', who is quite dead at the beginning of the story.

** ''[[IT]]'' also contains an appearance by Charles Pickman, from the [[H.P. Lovecraft]] story ''Pickman's Model'' - which ties it to all the Lovecraft stories mentioned below. King's next novel, ''[[The Tommyknockers]]'', not only crossed over with ''It'', but also tied in several of King's other novels, including ''Firestarter'' and ''[[The Talisman]]''.

*** Also Randall Flagg's spell book was heavily implied to be the Necronomicon

*** Also, the books ''Dolores Claiborne'' and ''Gerald's Game'' refer to each other as the female protagonists of the books have a psychic link, having times when they suddenly get the feeling that this other person, who they don't know, is somehow in danger.

** And [[Peter David]], writer of ''Dark Tower'' comics prequels has a character from his comics [[X Factor]] visiting place that is implied to be the same one Roland comes from, adding [[Marvel Universe]] into the mix. And considering Marvel also has ties to abovementioned Super Robot Wars clusterfuck, we better leave it at this.

Line 70:

** And the sequel threw ''[[Eberron]]'', ''[[Teenage Mutant Ninja Turtles]]'' and ''[[30 Days of Night]]'' into it. Which makes a lot of things mentioned above even more messed up than they already were.

** With the ''[[Doctor Who]]''/''[[Star Trek: The Next Generation|Star Trek the Next Generation]]'' crossover [[Star Trek the Next Generation Doctor Who Assimilation 2|Star Trek: The Next Generation/Doctor Who Assimilation]]<sup>2</sup> coming out the IDW ''Doctor Who'' comics are part of the IDW multiverse.

** Let's not forget that there was an ''[[The X-Files|X-Files]]'' ''[[30 Days of Night|Thirty Days of Night]]'' crossover a while back. Which considering how ''X-Files'' crossed over with ''[[Law & Order|Law and Order]]'' brings in every spin-off and international version of ''Law and Order'' into the IDW multiverse but also ''[[In Plain Sight]]'', ''[[Homicide: Life On the Street]]'', and ''[[Hawaii Five-O|Hawaii Five O]]'' and to a lesser extent ''[[The Wire]]'' and ''[[Arrested Development (TV series)|Arrested Development]]''.

*** [[The Simpsons (animation)|The Simpsons]] might fit somewhere what with the Mulder and Scully appearing in a Simpsons episdoe as a parody of the X-Files.

* Prior to the [[Tomb Raider]] Top Cow comic book Lara Croft would crossover with Witchblade. Since then she would have tons of other crossovers with Witchblade to the point it was impossible to say she wasn't part of the Top Cow universe, until her series ended and Top Cow lost the rights to Lara. A notable example is Lara being part the Monster War event.

* [[Hack Slash]] is treated to part of the same universe of the ''[[Re-Animator]]'', the Living Corpse comic, ''[[Child's Play (film)|Child's Play]]'', as well as the [[Lady Death]] Multiverse since Evil Ernie was reborn into the Hack/Slash universe after his latest death. Plus by extension [[Nightmare On Elm Street|Freddy]], [[Friday the 13th|Jason]], and [[Evil Dead|Ash]] are part of this universe because of the Evil Dead Re-Animator crossover.

** It makes sense seeing as how the creator of Hack/Slash believes that all slasher films and comics take place in the same universe.

* [[Savage Dragon]] treats the [[Mars Attacks!]] crossover as canon by having Damien Darklord a character who was created as a consequence of the crossover. This means at least the [[Savage Dragon]] part of the Image Universe is canon to [[Mars Attacks!]].

** Believe it or not there was a [[Sonic the Hedgehog]] and [[Image Comics]] crossover... that's STILL CANON!

* Terminator has had crossovers with [[Alien (franchise)|Alien S]] and [[Predator]], [[RoboCop]], [[Superman]] ,and the comic book [[Painkiller]] with each one considering Terminator to be canonically part of their universe. However thankfully every setting Terminator has crossed over obviously can't be in the same universe and at best all these storys can be considered [[Elseworlds]] preventing this becoming really confusing.

== Anime and Manga ==

* Manga creator [[Go Nagai]] does this often with his various works, although ''[[Mazinger Z]]'' and ''Grendizer'' were already part of one continuity from Grendizer's get-go.

** [[Shin Mazinger Shougeki! Z-hen]] is quickly reaching a critical level of this, with a woman from ''Violence Jack'' turning out to be {{spoiler|Kouji Kabuto's ''mother''.}}

** [[Violence Jack]] has incorporated [[Devilman]] and later [[Devilman Lady]] as taking place in one Universe {{spoiler|that resets itself and all main characters are really incarnations of Akira Fudou}}. And because the series is also [[Deconstructor Fleet]] for all other [[Go Nagai]]'s manga, there are many theories incorporating them into it {{spoiler|in all incarnations, which is possible thanks to the nature of this world}}. Cameos and crossovers between his works are so often it's pretty easy.

* Gosho Aoyama's three main works ''[[Detective Conan]]'', ''[[Magic Kaito]]'', and ''[[Yaiba]]!'', have the tendency to merge into one universe. ''[[Magic Kaito]]'' was more or less put on hold in favor of ''[[Detective Conan]]'', but its characters occur so frequently in ''[[Detective Conan]]'' to be the latter's recurring characters. Although, Aoyama also drew the line: ''[[Detective Conan]]'' does not deal with the daily life of the ''[[Magic Kaito]]'' characters.

** On the other hand, ''[[Magic Kaito]]'' is definitively ''in'' the same universe of ''[[Yaiba]]!''; the characters went to the same school called Ekoda, and the ''[[Detective Conan]]'' OVA Conan vs Kaitou Kid vs Yaiba was originally a ''[[Magic Kaito]]'' story arc (and not [[All Just a Dream]]), in which Kaito attempts to steal a magic sword, just before he found out what he was meant to be going after. Not to say, Aoko's gossip mill friend Keiko's "very reliable source" is Sayaka, the main girl in ''[[Yaiba]]!''.

* ''[[Turn a Gundam (Anime)|Turn a Gundam]]'' broadly hinted that each of the different [[Alternate Continuity|Alternate Continuities]] of the ''[[Gundam]]'' [[Ficton|franchise]] to date were part of a grander history -- with plenty of [[The End of the World as We Know It|disasters]] to [[After the End|reset the clock]] between settings.

* ''[[Turn A Gundam (Anime)|Turn a Gundam]]'' broadly hinted that each of the different [[Alternate Continuity|Alternate Continuities]] of the ''[[Gundam]]'' [[Ficton|franchise]] to date were part of a grander history -- with plenty of [[The End of the World as We Know It|disasters]] to [[After the End|reset the clock]] between settings.

* The mangaka group [[CLAMP]] has been known for self-crossovers for many years, but their twin series ''[[Tsubasa Reservoir Chronicle]]'' and ''[[xxxHolic]]'' are meant to tie all their works--both present-day and fantasy--into a single continuity.

* ''[[Pretty Cure All Stars]].'' 14 magical girls from 4 different continuities save the day. Awesome.

Line 108:

== Comic Books ==

* [[Jack Kirby]] is the [[Trope Codifier]].

** Nowhere is it more extremely apparent than The Secret City Saga (an unsuccessful imprint of Topp Comics created by Kirby using unused ideas from other company's all set in the same universe). Among the most notable was Captain Victory being heavily implied to be [[New Gods|Orion's son]], Teen Agents meeting The Liberty Project from Eclipse Comics, and [[Friday the 13th|Jason Voorhees]] appearing in an issue of Satan's Six (which it was taken even further with them battling in hell suggesting that this took place in between Friday the 13th: The Final Friday) .

* The [[The DCU|DC]] and [[Marvel Universe|Marvel]] universes were born from this trope; originally, the titles published by each company did not overlap, but over time, cameos, [[Crossover|Crossovers]], and inside references combined to form the comic books into one big, interconnected web. That's not even counting the Amalgam universe.

** Mind, Marvel started this with the first issue of ''[[Spider-Man]]''. And even before that, Marvel started this 21 years earlier in the Timely Comics era, when Human Torch faced off against Namor the Submariner for the first time. They teamed a few more times over the next few years, and some of the less prominent characters occasionally got involved. Then, in 1946, Timely launched the All-Winners Squad, teaming up existing characters like Captain America, the Human Torch, and the Sub-Mariner (among others)

** DC started it twenty years earlier in All-Star Comics #3 with the Justice Society's first meeting. To this day, it's generally accepted that the Justice Society is the first-ever example of a super hero team lasting longer than a single issue in comics history.

** DC has also historically made a habit of assimilating the characters of other comics companies into their multiverse - Quality Comics (Uncle Sam and the [[Freedom Fighters (comics)|Freedom Fighters]], [[Plastic Man]], [[Blackhawk]]), Fawcett Comics ([[Shazam|Shazam, Captain Marvel and the Marvel Family]]), [[Charlton Comics]] ([[Captain Atom]], [[Blue Beetle]], [[The Question]]), [[Wildstorm]] Comics ([[The Authority]], [[Wild CATS]]), [[Milestone Comics]] ([[Icon]], [[Hardware (comics)|Hardware]], [[Static (comics)|Static]], etc) and most recently, [[Archie Comics]]' Red Circle superhero characters. Generally, these characters start off in alternate timelines, and then some sort of universal crisis reboots the DC Universe yet again, merging the timelines.

* Back when comic crossovers where more common [[Marvel Comics|Marvel]] and [[DC Comics]] would have crossover one shots that would treat the Marvel and DC characters being in the same universe. However as time progressed most crossovers between the two companies involved inter-dimensional travel until in 2003 Marvel and DC crossovers outright stopped after JLA/Avengers. But Marvel would continue to have crossovers that would have characters be in the same universe and thus Earth-7642 of the Marvel Multiverse was born.

** ''[http://www.marvunapp.com/Appendix3/earthcrossoverall.htm A list of all the crossovers that happen on this Earth as well as an accurate timeline can be found here]''

* [[Strikeforce Morituri]] was a Marvel comic book about an alien race known as The Horde invading Earth and as a result a scientist creating a process to give any four people super powers and enhanced physical abilities. A few years after the Strikeforce comic ended it was designated as Earth-1287 in the Marvel Multiverse. However despite being part of the Marvel Multiverse Strikeforce has no real connection to the Marvel Universe except the Horde having [[Captain America]]'s shield, [[Silver Surfer]]'s board, and Galactus's helmet as trophies and the Weapon X member, Maverick from ''[[Exiles]]'' being a resident of this reality where he works for S.H.I.E.L.D. And let's be clear that the first example was a just gag and the second has been said to be a mistake made by the writer.

And let's be clear that the first example was a just gag and the second has been said to be a mistake made by the writer.

* Recently DC made a comic called [[First Wave DCU|FirstWave]] that crossed over ''[[Batman]]'', [[Doc Savage]], and [[The Spirit]] as well as having Rima the Jungle Girl having a small role and [[The Avenger]] being a back up story in the Doc Savage ongoing. It makes sense considering how it's supposed to be an alternate universe with no heroes outside of pulp characters.

** Interestingly [[Doc Savage]] and [[The Shadow]] where for a brief time a part of the main DCU (albeit the Silver Age Earth One back when it was the main universe) before [[Crisis on Infinite Earths]] happened.

* ''[[Image Comics]]'' is an interesting case. Originally, all of its titles took place in a shared universe. Over time, the original Image partners focused on their own corners of the Image Universe, causing the continuity to split into several distinct sub-continuities. The ''Shattered Image'' crossover made the split official. But Image partners still occasionally "borrowed" each others' characters, so the sub-universes still interacted. As new, non-partner creators become more prominent in Image Comics, they started building universes of their own, and they occasionally used the Image partners' characters. For example:

** Characters from Jay Faerber's creator-owned series (''[[Noble Causes]]'', ''Venture'', ''Firebirds'', & ''[[Dynamo 5]]'') appear in each other's books all the time, creating a loose-knit "Faerberverse".

** Robert Kirkman's characters occasionally cross over in a similar fashion (and some times become supporting cast - especially in ''[[Invincible]]'').

*** The Kirkmanverse and Faerberverse intersect at a number of points, especially The Pact mini-series. Other Image characters, such as [[Savage Dragon]] and [[Shadow Hawk]], often pop up. So far, however, [[Spawn]] had yet to make an appearance...

*** ...Until the recently announced ''Image United'', which brings together characters of all of the current Image partners (Erik Larsen, Rob Liefeld, Todd McFarlane, Marc Silvestri, Robert Kirkman, and Jim Valentino), as well as Whilce Portacio and several other creators.

Line 127:

* [[Teenage Mutant Ninja Turtles (comics)|Teenage Mutant Ninja Turtles]] is an interesting case as just about every crossover is canon to some degree.

** Miyamoto Usagi has crossed over with the turtles in three separate continuity's: the original comic book, the 1987 cartoon, and the 2003 cartoon. However in each incarnation it's stated that Usagi comes from a different dimension.

** The turtles are also part of the Savage Dragon side of the Image Universe having multiple crossovers with him (including the second Savage Dragon issue) and having their own series made by Image.

** [[Cerebus the Aardvark]] crossed over with the turtles in their eighth issue due to the time traveler Renet bringing them to 16th century England. Also despite Renet being an original crossover character she would continue to appear in later [[Teenage Mutant Ninja Turtles]] comics and the 2003 cartoon.

** Cerebus and the turtles would team-up again in Miami Mice.

** The Archie version of the turtles would crossover with Archie Andrews himself after Cudley (a giant inter-dimensional cow head) accidentally sent them there. [[Atop the Fourth Wall|Linkara]] had a review saying how stupid that sounds.

** The turtles had a crossover special with the Last of the Viking Heroes through, you guessed it time travel.

** The turtles are connected to the Big Bang Comics universe after a crossover with Knight Wathcmen.

* The ''Harlem Heroes'' strip in ''[[2000 AD|Two Thousand AD]]'' (about a basketball team with jetpacks in 2050) appeared to be totally unconnected to the 22nd centuy of the ''[[Judge Dredd]]'' universe until the son of one of the Heroes (John "Giant" Clay) joined the Judges (as Judge Giant). The ''[[Judge Dredd]]'' story "Hammerstein" suggested ''ABC Warriors'' was also set in the past of the Dreddverse, but later ''ABC Warriors'' stories contradicted this.

** Dredd has also had crossovers with other ''2000 AD'' strips whenever the writers felt like it, most notably ''[[Strontium Dog]]'' and the story Helter Skelter (where [[Garth Ennis]] basically crossed ALL his favourite strips over with Dredd).

** Meanwhile, ''2000 AD'' stalwart Pat Mills has crossed over ''everything he's ever written for 2000 AD'' with each other. Invasion!/Savage, Flesh, Ro-Busters, ABC Warriors, and [[Nemesis the Warlock]] all slot together.

** Ian Edginton does the same thing with his ''2000 AD'' strips: both ''Stickleback'' and ''The Red Seas'' share a secret organisation, little mentions and character cameos abound, and the same brand of [[Cosmic Horror]] appears in ''Stickleback'', ''Ampney Crucis Investigates'', and arguably ''Detonator X''.

** John Smith did a similar thing from the start in order to make his stories stand out: all his initial ''Future Shocks'' linked in to an organisation called Indigo Prime, and a couple of Indigo Prime agents also appeared in ''Tyranny Rex''. Indigo Prime then got its own series, and eventually crossed over with Smith's [[DC Comics]] series, ''Scarab''.

Line 142:

** As an aside, Moore is a close friend to Moorcock, close enough that Moorcock has allowed Moore to put in some Moorcock characters into the ''League'' series free of charge.

* [[Frank Miller|Frank Miller's]] [[Batman]] stories: ''[[The Dark Knight Returns]],'' ''[[Batman: Year One]],'' ''[[The Dark Knight Strikes Again]],'' and ''[[All-Star Batman and Robin The Boy Wonder|All-Star Batman and Robin]]'' were originally supposed to be in separate universes, with only ''[[The Dark Knight Returns]]'' and ''[[The Dark Knight Strikes Again]]'' having any clear continuity with each other. With the restoration of the DC [[The Multiverse|Multiverse,]] all of the [[Frank Miller]]-penned Batman stories are now set in Earth-31, which makes ''Year One'' unique in being canon to both Earth-31 and the main DCU.

** Subverted with the Spawn/Batman crossover that was originally canon to Earth-31 but has been ignored due to legal issues. Also the only real thing making it canon in the first place was Batman obtaining the robotic gloves he had in [[The Dark Knight Strikes Again]].

* [http://www.bleedingcool.com/2009/10/01/the-mark-millar-tie-up-athon-spoilers/ This article] suggests that all of [[Mark Millar]]'s recent Marvel work (''1985'', ''[[Fantastic Four]]'', ''[[Kick-Ass]]'', and ''[[Wolverine|Old Man Logan]]'') is all interconnected.

** Even ealier Millar estabilished connections between three comics published by different companies - ''[[Wanted]]'', ''[[Chosen]]'' and ''[[The Unfunnies]]''. The reason why at the end of the ''Chosen'' {{spoiler|media doesn't report Antichrist's miracles is that they're controlled by supervillains from ''Wanted''}}. And Troy Hicks from ''Unfunnies'' {{spoiler|helped Satan rape Antichrist}}. Never published ''Run!'' was supposed to be set in that world too.

** Even though Millar has stated many times that there will never be a sequel to Wanted he did allow Erik Larsen to write a two part story where The Fraternity looting the Image universe and fighting Savage Dragon. Considering how Mister Rictus appears in it, it's safe to say it isn't a follow up to the actual Wanted comic itself and more of an [[Interquel]].

* [[Grant Morrison]]'s ''[[All-Star Superman]]'' and ''[[DC One Million]]'' seemed to be tied in the same continuity.

** Of course, [[Grant Morrison]] is one of the architects of [http://www.hyperborea.org/flash/hypertime.html Hypertime] (the other being Mark Waid) which posits that it is all true. Under this concept, the events of ''DC vs. Marvel'' exists somewhere in continuity.

** Arguably, almost all of Morrison's DC works are tied to each other, ''as well to the [[Real Life|real world]]'', forming a big "Morrisonverse". Here's how it goes: In ''All-Star Superman'' Superman creates the infant universe Qwewq. In ''[[Justice League of America|JLA]]'' we see the heroes discover (a version of) Qwewq. Both in ''ASS'' and in ''JLA: Confidential'' we see that Qwewq actually contains "our" Earth, i.e. a realistic Earth with no superheroes. The final Morrison-penned issues of ''[[Doom Patrol]]'' and ''[[Animal Man]]'' take place in a realistic world with no superheroes (and they both share the same colour scheme, meaning it's the same world in both), which is presumably Qwewq, i.e. "our" world. In ''[[Seven Soldiers]]'' we find out the ultimate fate of Qwewq (or at least one version of it). ''[[Final Crisis]]'' (which takes place in the same universe as ''JLA'') refers to Bleed (the "sea" that separates different universes in the DC multiverse) as "ultramenstruum", and the same term is used is ''[[The Invisibles]]'', implying that the Invisibles universe is a part of the larger DC multiverse. Finally, if we accept that Qwewq is "our" universe, this means our universe exists inside a larger universe populated by superheroes. Both ''[[Flex Mentallo]]'' and ''[[The Filth]]'' feature the "real" world to which superheroes from outside this world burst in; thus, the real world in both these comics could be (a version of) Qwewq. To sum it up, almost all of Morrison's major works for DC are welded together, though admittedly some of the links between them are vague.

** A huge chunk of the story's featuring the future adventures of Damian Wayne are interconnected through lots of his work too. In [[DC One Million]] there is a reference to 2 Face 2 by Batman 1000000 who says that Bruce Wayne's successor managed to reform him after showing that 2 Face 2 despite using the coin gimmick did more evil than good. Next in Batman #666 Damian Wayne is shown to have taken full control of the mantle after Bruce's death and making a deal with the Satan to live forever in exchange for his soul, that way he can properly defend a nearly destroyed Gotham. Years later in Batman #700 Damian finally has a fight with 2 Face 2 who has kidnapped and given Joker venom to [[Batman Beyond|Terry McGinnis]] thinking he is the son of a rich software magnate. In the proceeding battle Terry is cured and a injury to 2 Face 2's head brings out his good side. Damian proceeds to give Terry the title of Batman after he retire's.

* When Semic Comics, a French comic publisher, decided to revive the characters it inherited from defunct ''Editions Lug'', editor Jean-Marc Lofficier set out to link over 2000 largely unrelated characters from just about every comic book genre into a single continuity. Some characters had to be revamped fairly drastically to fit in, and a few had to be revamped to avoid duplication.

* There's a curious variation of this with Marvel's UK comics, their British branch. In addition to reprinting Marvel Comics, they also created their own, original characters (Death's Head probably being the best known) that were assumed to be part of the [[Marvel Universe]] from the start; many Marvel heroes [[Crossover|guest starred]] in their series, but the American comics rarely if ever acknowledged them. Technically they are still canon, though most of them haven't been seen since the 90's and almost never get mentioned today.

* The entire premise of Killraven is that centuries ago in original the Guardians of the Galaxy continuity the Martains of [[War of the Worlds]] invaded Earth and destroyed all superheroes with only freedom fighters left to fight back. Furthermore another version of Killraven known as "Ape Slayer" appeared in the UK [[Planet of the Apes]] comics. So yeah... [[Planet of the Apes]] and [[War of the Worlds]] are part of the Marvel Multiverse.

* Before the various legal issues of ''[[Miracleman]]'', he appeared in one panel of Captain Britain where he lived on Earth-238 and married to Captain UK. Of course to prevent legal issues he was killed in that same panel. However this is interesting as this issue was the first time he was even called Miracleman, which would be his new name in later years.

* With Shi this is [[Turned Up to Eleven]] because she's crossed over ''[[Vampirella]]'', [[Lady Death]], Grifter, Razor from London Night Studios, Omega One (a team from Ant), Avengelyne, [[Fallen Angel]], ''[[Gen 13]]'', ''[[Wolverine]]'', and ''[[Daredevil]]''.

** In fact it surprisingly gets worse seeing as how in the one shot crossover Shi/Cyblade has both these characters crossing over with ''[[Spider-Man]]'', [[The Darkness]], ''[[Witchblade (Comic Book)|Witchblade]]'', ''[[Hellboy (comics)|Hellboy]]'', ''[[Madman (Comic Book)|Madman]]'', [[The Tick]], [[Usagi Yojimbo]], Mr.Spook, Samaritan (from [[Astro City]]), [[Cerebus the Aardvark]], Hellshock, [[Scud the Disposable Assassin]],[[Strangers in Paradise]], ''[[Bone]]'', Ash (the one from Event Comics not from [[Evil Dead]]), Eudaemon (from [[Dark Horse Comics]]), [[Fun With Milk and Cheese]], ''[[Johnny The Homicadal Maniac]]'', Kabuki (from [[Icon Comics]]), and Bryd (from the comic Mr. Monster)!!! And let's remember that all these characters crossed over in only a ONE SHOT COMIC!!!!

** In fact it surprisingly gets worse seeing as how in the one shot crossover Shi/Cyblade has both these characters crossing over with ''[[Spider-Man]]'', [[The Darkness]], ''[[Witchblade (Comic Book)|Witchblade]]'', ''[[Hellboy (comics)|Hellboy]]'', ''[[Madman (Comic Book)|Madman]]'', [[The Tick (animation)]], [[Usagi Yojimbo]], Mr.Spook, Samaritan (from [[Astro City]]), [[Cerebus the Aardvark]], Hellshock, [[Scud the Disposable Assassin]],[[Strangers in Paradise]], ''[[Bone]]'', Ash (the one from Event Comics not from [[Evil Dead]]), Eudaemon (from [[Dark Horse Comics]]), [[Fun With Milk and Cheese]], ''[[Johnny The Homicadal Maniac]]'', Kabuki (from [[Icon Comics]]), and Bryd (from the comic Mr. Monster)!!! And let's remember that all these characters crossed over in only a ONE SHOT COMIC!!!!

** And let's not forget that these titles have crossed over with other comics too. Madman has teamed-up with ''[[Powers]]'' and ''[[Superman]]'', ''[[Hellboy]]'' crossing over with [[Savage Dragon]], [[The Goon]], Ghost, and [[Beasts of Burden]], Mr. Monster crossing over with Airboy, [[Fun With Milk and Cheese]] appearing in ''[[Hack Slash]]'', [[Usagi Yojimbo]] being a part of the [[Teenage Mutant Ninja Turtles]] multiverse, Johnny the Homicidal being in the same universe as [[Invader Zim]], and many characters not mentioned above being apart of the Image Universe. In other words almost every comic book in existence is part of a messed up multiverse all because of one character!

* A robot known as Tin is heavily hinted to be Tintin and lives on a post apocalyptic future of Earth-Eleven of the Pre-Crisis DC Multiverse.

== Film ==

* Present in horror films long, long before [[Freddy vs. Jason]]. In the [[Universal Horror]] series, ''[[Frankenstein Meets the Wolf Man]]'' triggered the tendency to pile on the monsters, insisting that Dracula, the Wolf Man and Frankenstein's Monster all existed in a common universe. This does not work well with continuity (''[[The Wolf Man]]'' takes place in the present day while the others happen in a dimly-characterized past), but they didn't care much by that point (Universal's horror films of the 40s are strikingly dumber and more juvenile than those of the 30s).

* [[Quentin Tarantino]] did this by [[Word of God]] with his viarous movies including ''[[Reservoir Dogs]]'', ''[[Pulp Fiction]]'', ''[[Inglourious Basterds]]'', ''[[True Romance]]'' and ''[[Kill Bill]]''. Connections may be spreaded to the point of setting almost every movie he ever worked on into the same Universe.

** Not so much [[Word of God]] given the fact that the characters do make passing references to each other. Even though [[True Romance]] was already sold to pay for [[Reservoir Dogs]] production, Alabama is still mentioned by Mr White.

** What [[Reservoir Dogs|colour]] is a [[Pulp Fiction|Pumpkin]]? The answer is why Tim Roth played the part.

** Also, Red Apple Ciggarettes

* In all honesty [[Alien (franchise)|Alien]] and [[Predator]] where never really meant to part of the same universe. The Xenomorph head from Predator2 was only meant as a joke but inspired dozens of video games and comic books until the connection was made completely canon in the [[Alien vs. Predator]] movies.

Line 171:

* Fantasy author [[Michael Moorcock]] gradually connected almost every single character he'd created into a [[Myth Arc]] revolving around the concept of the [[Cosmic Plaything|Eternal Champion]]. Indeed, this article was originally titled "The Moorcock Effect" in reference to him.

** Given that his [[Doctor Who]] novel ''The Coming of the Terraphiles'' features a ''Captain'' Cornelius, who may or may not be another aspect of the Eternal Champion (much like [[Jerry Cornelius]]) that probably ties the Eternal Champion into the Whoniverse as well! There's also a "Second Aether", which, spelling aside, ties the Whoniverse to the ''Second Ether'' sequence.

** [[Michael Moorcock]] also helped write a Conan and [[The Elric Saga]] crossover for Marvel Comics.

* [[Robin Hood]] went through several rounds of this, along with [[Adaptation Displacement]]. Maid Marion, Friar Tuck, and Alan-a-Dale were all characters from separate folk tales, and it was only later that Robin Hood stories had anything to do with Richard the Lionheart or Prince John.

* In the 1980s, [[Isaac Asimov]] wrote a series of novels that linked his ''Robots'', ''Empire'', and ''[[Foundation]]'' novels into a single continuity. He also even went so far as to in ''Foundation and Earth'' suggest (via throwaway reference in dialogue) a tenuous connection between the Robots/Empire/Foundation series and an otherwise seemingly unrelated, comparatively obscure time-travel novel, ''[[The End of Eternity]]'', which he wrote in the 1950s (interestingly enough, if they ''were'' in the same continuity, the end of the novel would effectively have caused the ''entirety of the events in the rest of the series'', because said ending {{spoiler|revolves partly around allowing humanity to expand into space instead of mouldering on Earth}}).

** Don't forget throwing in a reference to his standalone novel Nemesis in one of the later Foundation books, despite the fact that Nemesis and the Robots/Empire/Foundation books taking place in the same universe makes no sense whatsoever (not even the space-travel physics work the same way).

Line 188:

* [[Larry Niven]] originally had two continuities: the first was the "slowboat" stories of early colonization of space by humanity (featuring the novels "World of Ptaavs", the Gil Hamilton stories, and "A Gift From Earth"), while the second featured faster-than-light travel and aliens (featuring the stories of Beowulf Shaeffer, Louis Wu, and the [[Ringworld]]. And then he wrote his short story "Relic of Empire", which combined the two continuities and created the ''[[Known Space]]'' universe.

* The first novel in [[Terry Pratchett]]'s [[Nomes Trilogy]], ''Truckers'', takes place in the (real) town of Grimethorpe, but in the later books the Store is relocated to Blackbury, which is also the setting of the [[Johnny Maxwell Trilogy]].

* [[Edgar Rice Burroughs]] did this when ''[[Tarzan]]'' first traveled to the underground world of Pelucidar to rescue that title's hero. It grew from there under his pen and under the pen of others using his characters.

** There was a series of action figures: "Tarzan on Mars". Of course, poor Edgar had nothing to do with it.

** In ''A Fighting Man of Mars'', Jason Gridley appears. Since Gridley met Tarzan in Tarzan At the Earth's Core, a Pellucidar novel, this links Tarzan, Barsoom, and Pellucidar.

*** Gridley is also mentioned in the Amtor (Venus) series, linking those five books as well.

*** Tarzan is mentioned by the narrator as having participated in some historical event prior to the main story of the first story. Even then, the Tarzan books, and by association, everything Tarzan had appeared in, were part of the Amtor universe within the first twenty five pages of Pirates of Venus.

**** Also, the technology for the Moon mission from ''The Moon Men'' was Barsoomian in origin.

Line 205:

** [[Clark Ashton Smith]]'s Xiccarph and Zothique series were not originally connected to the [[Cthulhu Mythos]]. They were tied into the Mythos by later writers.

** Lovecraft and others also tied some works by earlier writers into the Mythos:

*** [[Robert W. Chambers|RW Chambers]]' ''[[The King in Yellow]]'' (referenced in "The Whisperer in Darkness").

*** Occasional references to [[Lord Dunsany]]'s fiction, such as the city of Bethmoora.

*** A few references to [[Arthur Machen]], such as the Aklo language.

Line 212:

** Though to be fair, from the beginning the Chee stories (which came second) would reference Leaphorn and characters and events from his stories--they just weren't featured in the same books for a while.

* First ''The Poet'' and ''Blood Work'' got sucked into [[Michael Connelly]]'s Harry Bosch universe, now ''Void Moon'' has been caught in the gravity well, too. Of course, unlike many of the other entries here, Harry Bosch's "world" is that of LAPD Homicide, and so referencing or including a few of Michael Connelly's stand alone novels doesn't really require much in the way of a [[Retcon]].

* Before he's done, F. Paul Wilson's ''Adversary Cycle'' bids fair to weave in practically every book and short story the man has ever written.

* [[Mercedes Lackey]]'s assorted [[Urban Fantasy]] stories seem to be set in different continuities, until mention is made of the west coast elfhames (from the ''Bedlam's Bard'' series) in the SERRAted Edge novels, and of Tannim, the mulleted protagonist of the SERRAted Edge novels appearing as a bit character in his teens in ''Jinx High'', a Diana Tregarde investigation.

** Since ''Jinx High'' was Tannim's first appearance, and the ''Bedlam's Bard'' events were namechecked in the first SERRAted Edge novel, this one was evidently intended from the start, or nearly so.

Line 225:

** Tommy and Tuppence can also be linked to the others through a mysterious character who is only referred to as Mr. Robinson. This character appears with Poirot in ''Cat Among the Pigeons'', Marple in ''At Bertram's Hotel'', and Tommy and Tuppence in ''Postern of Fate''. He also appears in ''Passenger to Frankfurt'', which does not feature any of Christie's series detectives.

* While [[Kim Newman]] has seeded connections between his books since the beginning, the short story "Cold Snap" seems to be a concentrated effort to tie them ''all'' together. A "[[Diogenes Club]]" story (and therefore featuring characters whose [[Alternate Universe]] selves appear in the ''[[Anno Dracula]]'' novels) it adds characters from his early work such as ''Jago'', and even features the villain from his ''[[Doctor Who]]'' novella ''Time And Relative''.

** Under the pseudonym Jack Yeovil, Newman wrote a number of books based on Games Workshop properties. ''Krokodil Tears'', one of the ''[[Dark Future (novel)|Dark Future]]'' books, had its [[Big Bad]] have a vision of an alternate version of himself as the Big Bad from his Vampire Genevieve series of ''Warhammer'' books.

** Krokodil Tears goes futher with Jason Voorhees and other film murders stated to be asylum inmates.

*** [[Kim Newman]] also helped Eugene Byrne write a book called Back in the USSA that mentioned Genevieve Dieudonne being a normal sixteen year old girl living in a Communist America and had a love song written for her.

*** Genevieve was also was mentioned to be part of a [[Charlie's Angels]] type of group led by Erik of [[The Phantom of the Opera]] in a story called Mark of Kane that was collected in Tales of the Shadowmen Volume 4. Futhermore Tales of the Shadowmen is an anthology series that takes place in a universe where all characters of adventure literature are in the same universe.

* [[Kim Newman]] isn't the only author to tie his personal [[Verse]] into the [[Whoniverse]]. Iris Wildthyme was a character in Paul Magrs' [[Magic Realism]] novels, before he revealed she was an extremely eccentric Time Lady.

** Iris Wildthyme, in her appearances in novels and audios, occasionally interacts with an organisation called MIAOW, The Ministry for Incursions And Other Wonders (simultaneously a parody of [[Torchwood]] and ''[[Doctor Who]]'''s UNIT). This organisation has also turned up in his Brenda and Effie series of novels set around Whitby. Charaters from his [[Eighth Doctor Adventures]] novel ''Mad Dogs and Englishmen'' have also appeared in this series. A character from one of Magrs' Tenth Doctor novels also reappeared in an Iris Wildthyme short story, along with a character from the Brenda and Effie series.

Line 288:

** Which is mostly a case of converting some things to MDC. Other than that, every Palladium game uses the same basic rules. Another bit of [[Canon Welding]] comes in-universe. Hints have been dropped in the books that Rifts Earth is either a future version of ''Beyond the Supernatural'', ''Heroes Unlimited'', or a bizarre combination of the two.

* The ''[[Warhammer Fantasy Battle]]'' and ''[[Warhammer 40000]]'' universes (universi? universeses?) used to be linked, although the linking statements were made by mad characters. The whole saga/background is told through an [[Unreliable Narrator]] anyway. [[Word of God|Games Workshop]] has stated that the link is now done away with, since it was mostly silly anyway.

** To elaborate, Warhammer world used to be a planet in the 40k universe, surrounded by warp storms that made it inaccessible for the rest of the galaxy. Nowdays they exist in separate universes, but there appears to be a small link between them in the form of the Warp (the Chaos Gods are the same in each universe, and some people in Warhammer world have gotten visions of Chaos in 40 universe. For example, in ''Liber Chaotica: Book of Khorne'', it's all but outright stated the author is having visions of Abaddon's 13th Black Crusade. Also the [[Precursors|Old Ones]] in ''Warhammer'' appear to be the same as the ones in 40k, and a fan theory suggests they escaped from 40k universe to ''Warhammer'' one after the War in Heavens). There is no real interaction between the two universes, however, unless you count some daemon characters popping up in both universes and a few magic items that have a suspicious resemblance to 40k technology.

** It also used to be fairly heavily implied that Sigmar (the fantasy Empire's messiah figure and founder) was one of the missing Primarchs (genetically enhanced superhuman offspring of 40k's Emperor).

** Warhammer 40 000 is now considered to be simply the [[Spiritual Successor]] where everything is an [[Expy]] of the original Warhammer Fantasy.

Line 303:

* When SNK made ''Art of Fighting 2'', they decided to officially make the ''[[Art of Fighting]]'' series part of the same [[Continuity]] as the ''[[Fatal Fury]]'' series. To explain why the ''[[Art of Fighting]]'' cast were not around during the events of the ''[[Fatal Fury]]'' games, they made the ''[[Art of Fighting]]'' series a [[Prequel]] to the ''[[Fatal Fury]]'' series by setting it ten years before and putting a young Geese Howard as the [[True Final Boss]] in ''Art of Fighting 2'' (back when he was still the police commissioner of South Town). When SNK later wanted to cross the ''[[Fatal Fury]]'' cast with the ''[[Art of Fighting]]'' cast in ''[[The King of Fighters]]'' games, they had to place the third series in a separate [[Continuity]].

** And from there, it starts getting ''really'' weird, with Ralf and Clark from ''[[Ikari Warriors]]'' and Athena from ''[[Psycho Soldier]]'' (who is the descendant/ambiguously-the-reincarnation of the Athena from ''[[Athena (video game)|Athena]]'') appearing in ''[[The King of Fighters]]'' -- despite ''Psycho Soldier'' involving an invasion of monsters from beneath the Earth that you'd kind of think would get mentioned at some point in ''King of Fighters'' canon if it happened -- and then both Ralf and Clark and ''King of Fighters'' original Leona appearing in ''[[Metal Slug]] 6'' and ''[[Metal Slug]] 7''. At this point, the only sane response to the [[SNK]] canon is to throw up your hands and shout "I don't know!"

* The ''[[Final Fantasy]]'' series has a few counts of direct crossover, such as Gilgamesh (seems to be the same person in every game he appears in) and Cloud (who features as a guest character in ''[[Final Fantasy Tactics]]'').

** Ivalice Alliance series was the first attempt to make a Final Fantasy universe that included more than one game and in fact includes games without the Final Fantasy name. ''[[Vagrant Story]]'', ''Final Fantasy Tactics'',[[Crystal Defenders]], and the [[Development Hell|not yet released]] Fortress, and [[Final Fantasy XII]] series are among the comfirmed games to take place in the Ivalice universe.

** Similarly, hints have been dropped [[Final Fantasy X 2|here and there]] (and [[Word of God]] has outright stated) that ''[[Final Fantasy VII]]'' takes place in the far future of the ''[[Final Fantasy X]]'' world, on a different planet.

** Similarly, hints have been dropped [[Final Fantasy X-2|here and there]] (and [[Word of God]] has outright stated) that ''[[Final Fantasy VII]]'' takes place in the far future of the ''[[Final Fantasy X]]'' world, on a different planet.

** And then ''[[Dissidia Final Fantasy]]'' made it so they're all parallel worlds in a shared multiverse, although it's canonicity is uncertain. Would make sense, though. It is a series.

** ''[[Final Fantasy IV: The After Years]]'' reveals that every crystal-based Final Fantasy game is in the same universe. {{spoiler|The crystals are placed on a planet with promise, both to guide and record the evolution of the planets; hence why they all have humans, and not-entirely-different environments from the other Final Fantasies. To prove it, the party fights such recorded monsters as [[Final Fantasy I|The Four Fiends]], [[Final Fantasy III|the Dark World Crystal Guardians]], [[Final Fantasy V|Gilgamesh, and the superbosses Omega, Shinryu]], [[Final Fantasy VI|Death Gaze and Ultima Weapon]].}}

* When the Czech developers of ''[[Operation Flashpoint]]: Cold War Crisis'' (their first game) Bohemia Interactive Studios split with the publisher, they were able to keep the "assets" (i.e. the game engine) but not the name, so they ended up creating a [[Spiritual Successor]] called ''ARMA''. However, BIS has since come out and said that both series are in a [[Shared Universe]], as will be BIS' spin-off Take On Helicopters.

** The latest patch for Operation Flashpoint even renames it to ''ARMA: Cold War Assault''. Talk about paying attention to details.

* In a strange example, the version of ''[[Super Mario Bros.]]. 2'' that was released in the U.S.A. was, in fact, nothing more than a remake of another Japanese game called ''Yume Kōjō: Doki Doki Panic''. Since then enemies from ''Yume Kōjō: Doki Doki Panic'', such as Shy Guys, have made their way into Mario canon, despite being from a game that was never intended to be part of the Mario series.

Line 316:

* [[Elemental War of Magic]] shares a ''lot'' of its terminology (especially in its backstory) with [[Galactic Civilizations]], indicating that the game may be set on ancient Altaria and the channellers are [[Sufficiently Advanced Aliens]].

* ''[[Betrayal at Krondor]]'' and ''[[The Riftwar Cycle|Riftwar]]''.

* [[Easter Egg|Easter eggs]] in [[Sierra]]'s adventure games point to a shared continuity.

* [[Namco Bandai]] seems to have merged parts of the previously unrelated (despite numerous [[Shout-Out|Shout Outs]]) ''[[Galaxian]]''/''[[Galaga]]'' series, ''[[Ace Combat]]'' series, ''[[Ridge Racer]]'' series, and some other games into an overarching ''[http://acecombat.wikia.com/wiki/United_Galaxy_Space_Force United Galaxy Space Force]'' series.

* In the PC game series ''[[Dark Parables]]'', [[All Myths Are True|all fairy tales are true]], and they're all pretty much part of one gigantic story. [[Sleeping Beauty]] is sister-in-law to [[The Frog Prince]] and [[The Snow Queen|Gerda]] is descended from [[Hansel and Gretel|Hansel]], for starters.

Line 322:

** If the Space Core Mod in [[Elder Scrolls]]:Skyrim is canon then Nirn is a far off planet in the Half-Life Universe. Or an alternate dimension that the space core landed in through a Wormhole...[[Epileptic Trees|or something]].

* ''[[Commander Keen]]'' and ''[[Wolfenstein 3D]]'' are linked together by way of Commander Keen's Billy Blaze being the grandson of Wolfenstein's B.J. Blazkowicz. A common fan theory is that the protagonist of ''[[Doom (series)|Doom]]'' is also part of the family. The RPG versions of their respective games go with this - the "Harbinger of Doom" from ''Wolfenstein RPG'' is basically ''Doom'''s Cyberdemon without prosthetics, and the hero of ''Doom RPG'' is explicitly given the last name "Blazkowicz".

* Ever since [[Ninja Gaiden]] got rebooted in 2004 it has been part of the [[Dead or Alive]] with Ryu Hayabusa canonically winning at least one tournament. Also if one takes the Spartan-458 (Nicole) and the Ridley stage from Dead or Alive Dimensions (Samus originally being part of the game but only getting a cameo after each match) seriously then [[Halo]] and [[Metroid]] part of the Ninja Gaiden universe. It would definitively explain the Spartan Hayabusa armor.

** To a lesser extent [[Dynasty Warriors]] is connected to [[Ninja Gaiden]] too but it's pretty much stated that the Dynasty Warriors games take place in an [[Alternate Universe]].

* [[Super Smash Bros]] takes place in a universe where nearly every Nintendo character from a popular franchise exists as well as [[Sonic the Hedgehog]] and [[Metal Gear|Solid Snake]]. However the Super Smash Bros. Universe is an [[Alternate Continuity]] that has no effect on the other franchises at all.

* [[Super Smash Bros.]] takes place in a universe where nearly every Nintendo character from a popular franchise exists as well as [[Sonic the Hedgehog]] and [[Metal Gear|Solid Snake]]. However the Super Smash Bros. Universe is an [[Alternate Continuity]] that has no effect on the other franchises at all.

* Thanks to Playstation All-Stars Battle Royale [[Twisted Metal]], [[Sly Cooper]], ''[[Killzone]]'', [[Parappa the Rapper]], [[Fat Princess]], and many other series featured in Playsation franchises are all part of the one big multiverse.

* Capcom is probably hands down the all time God of this trope. With the the [[Marvel Universe]], [[Tekken]], [[SNK]], [[In Famous]], [[Pac-Man]], a majority of the [[Tatsunoko Production]] series, and numerous [[Namco]] series all crossing over, [[Capcom vs. Whatever]] isn't that much of a stretch.

** Since we're focusing on Capcom at the moment it's interesting to note that more series are connected to [[Street Fighter]] outside of the realm of fighting. [[Darkstalkers]] characters appeared in [[Cross Edge]] bringing in [[Mana Khemia]], Spectral Souls, [[Ar tonelico]], the [[Atelier Series]], and [[Disgaea]] and there's also ''[[Professor Layton vs. Phoenix Wright: Ace Attorney|Professor Layton vs. Ace Attorney]]'' to consider.

* [[Project X Zone]] is a massive crossover between [[Namco]], [[Capcom]], and [[Sega]] connecting a ton of their franchises to one another. However seeing as how Namco has connections to [[Super Robot Wars]] and Capcom has ties to everything [[Marvel Comics]] has crossed over with, we better stop talking before our heads explode.

== Webcomics ==

Line 368:

** The ''[[Kingdom Hearts (video game)|Kingdom Hearts]]'' series of video games, has most major Disney world, or rather, explicitly AU versions of them, existing in a larger multiverse.

* If one is to take [[Nicktoons Unite!]] and it's sequels seriously then [[SpongeBob SquarePants]], [[Danny Phantom]], [[Fairly Oddparents]], [[Jimmy Neutron]], [[Invader Zim]], [[My Life as a Teenage Robot]], [[Tak and the Power of Juju]], [[The Ren and Stimpy Show]], [[El Tigre]], and [[Catscratch]] form a [[Nickelodeon]] multiverse.

** The successor [[Nicktoons MLB]] might bring in [[Avatar: The Last Airbender]], [[Tuff Puppy]], and unfortunately [[Fanboy and Chum Chum]] into the Nick Toons continuity but seeing as how that it's just a sports game with no plot or explanation outside of ''Nicktoons characters are part of MLB teams'' there's no proof to say no or yes to this theory completely.

* In the ''[[South Park]]'' episode "Super Best Friends", there is a brief scene of the cast of ''[[That's My Bush]]'' in the White House, indicating that the two series (both created by Matt Stone and Trey Parker) take place in the same universe (which is particularly silly, since ''[[That's My Bush]]'' is a live-action show).

* In the ''[[South Park]]'' episode "Super Best Friends", there is a brief scene of the cast of ''[[That's My Bush!]]'' in the White House, indicating that the two series (both created by Matt Stone and Trey Parker) take place in the same universe (which is particularly silly, since ''[[That's My Bush!]]'' is a live-action show).

** And another [[Comedy Central]] show, ''[[Dr. Katz, Professional Therapist]].''

* There were reportedly plans to weld the canons of ''[[Exo Squad]]'' and ''[[Robotech]]'' back when the former was produced. Considering that their primary motivation seemed to be that both shows were [[Merchandise-Driven]], your mileage may vary on whether it's a good or bad thing that this never happened.

Line 378:

* ''[[Static Shock]]'' was welded into the ''[[DC Animated Universe]]''.

* ''[[The Critic]]'''s Jay Sherman once showed up to judge the ''[[The Simpsons]]''' Springfield Film Festival, though Matt Groening was so against the idea that he took his name off the opening credits for that episode.

* [[Transformers Generation 1]] have already been listed, but deserve special mention here; in the 80's, it was broadly hinted that the original cartoon shared a universe with the G.I. Joe cartoon, and not-quite-as-broadly that the same was true for ''[[Jem and The Holograms]]'' and ''[[Inhumanoids]]''. This has been taken much further in the 21st century, where not only were the previous hints confirmed, but now ''every'' Hasbro cartoon from the time period has been stated to be part of the same universe, and pretty much every other Hasbro property exists within the Transformers multiverse.

* Saying that ''[[Ben 10]]'' and [[Generator Rex]] are in the same universe is near impossible. Ben 10's about a kid protecting the Earth from alien menaces with a [[Lego Genetics|watch that can transform him into over a million different alien species]] and Generator Rex is about a teenager who helps a government agency know as Providence deal with a nanite infestation [[Inferred Holocaust|that makes every single person on the planet infused with nanites that can turn them into dangerous monsters at any given time.]] So when a crossover was announced between the shows they were both declared a [[Parallel Universe]] to one another. It makes some sense considering how every inconsistency in Ben 10 is said to be an [[Alternate Timeline]].

* While the [[Space Ghost]] crossover on [[Batman: The Brave And The Bold|Batman the Brave And The Bold]] was awesome, it makes things way too complicated since [[Space Ghost]] was originally in the same universe as Dino Boy, [[The Herculoids]], Shazzan, Mighty Mightor, and [[Moby Dick]] as well as being part of the [[Adult Swim]] universe consisting of [[Space Ghost Coast to Coast]], [[Aqua Teen Hunger Force]], [[The Brak Show]], [[Perfect Hair Forever]], [[Harvey Birdman, Attorney at Law|Harvey Birdman Attorney At Law]], and [[12 oz. Mouse]].

** But it gets even better seeing as how [[Batman: The Brave And The Bold|Batman the Brave And The Bold]] reminded us that [[Scooby-Doo (animation)|Scooby Doo]] fits in here somewhere. Additionally because of [[Scooby-Doo (animation)|Scooby Doo]] Batman and [[Space Ghost]] are connected to [[The Addams Family]], [[Speed Buggy]], [[The Three Stooges]], and [[Josie and the Pussy Cats]].

** While the two shows never fully crossed over [[The Powerpuff Girls]] and [[Dexter's Laboratory|Dexters Laboratory]] both had The Justice Friends appear once or twice implying that the two where part of the same universe. Also judging by the Space Ghost cameo they might be part of the Space Ghost Verse.

*** Furthermore due to numerous cameos, references, The Grim Adventures of the Kids Next Door, and Cartoon Network: Invaded it seems that [[The Grim Adventures of Billy and Mandy]], [[Ed, Edd 'n' Eddy]], [[Foster's Home for Imaginary Friends]], [[My Gym Partner's a Monkey]], and [[Camp Lazlo]] all these series seem to be part of the [[Powerpuff Girls]] universe.

*** It's probably a bad time to mention that [[Yogi Bear]] and [[The Flintstones|Fred Flintstone]] appeared in Billy and Mandy isn't it.

** [[Cartoon Network]]: [[Fusion Fall]] is a MMO that has almost every Cartoon Network show in existence in the same universe. This can create a lot of confusion seeing as how many shows contradict one another... but who cares!
