Intercontinuity Crossover: Difference between revisions

* ''[[Slayers]] VS [[Sorcerer Stabber Orphen|Orphen]]''

* Rodimus's backstory in ''[[Transformers Energon]]'' states that he left Cybertron with a band of Autobots and "traveled into the future", which reflects the ending of ''Transformers: The Headmasters'', in which he ventures off into space to find/found a new home planet.

* It's not much, but in G Gundam, during the finale episode where all the world's Gundams had banded together to fight the Dark/Devil Gundam, you can see Gundams from other series in the mob. For example, both the standard RX-78-GP01 and the RX-78-GP01 Full Vernian, the Wing Gundam, RX-78-2, etc. They weren't kidding when the said they had all the Gundams!

* Beginning with ''[[Alien vs. Predator|Predator vs. Aliens]],'' the two extraterrestrials have done battle (either one-on-one or multiplayer deathmatch) with essentially every superhero ever created, no matter how illogical the match-up. Taken to ridiculous extremes in ''[[Superman]] and [[Batman]] vs. Aliens and Predator.''

** Perhaps the most famous of these stories was ''[[Wild CATS]]/Aliens'' which actually had an impact on the former's continuity and saw the deaths of several members of ''Stormwatch'' to allow [[Warren Ellis]] to clear the decks to create ''[[The Authority]]''

** An interesting example: [http://30.media.tumblr.com/tumblr_lnacm5QoMK1qkz9yno1_500.jpg X-Men and Teen Titans]. Starfire learns languages by kissing people, and Nightcrawler thinks ''that's terrific''.

** An unfortunate side-effect of this is that the closest Jubilee has ever come to a serious relationship is with a guy who lives in another universe.

** On Elric's side this makes sense, as his home continuity is explicitly one of many parallel worlds.

* [[Judge Dredd (comics)|Judge Dredd]] has teamed up with [[Batman]] on at least three occasions; given Bats' vigilante status and Dredd's fascist asshole status, there was some distinctly [[Teeth-Clenched Teamwork]] on both sides. Dredd has taken on ''[[Alien (franchise)|Aliens]]'' and the ''[[Predator]]'' as well.

** ''[[Superdickery]]'' has some that are even worse.

**** ''[http://www.viruete.com/articulos/fotos%20articulos/superman-heman/HE-MAN%20vs%20SUPERMAN.jpg Superman/He-Man]''. It didn't suck as much as you thought it would, chiefly because this was ''before'' the cartoon debuted, and He-Man behaved more like the loinclothed barbarian he is. [http://www.encyclopedia-obscura.com/printcomicshemansuperman.html Also, no Orko.]

* When it was originally planned as a four-issue limited series, ''[[Transformers]]'' shared the same 616 universe as other Marvel characters. J. Jonah Jameson sent Peter Parker to Oregon to investigate the Transformers ([[Memetic Mutation|he wanted pictures of Optimus Prime]]) and thus Spidey and the Autobots teamed up. When the title became a monthly ongoing series, however, the crossover was [[Canon Discontinuity|quietly forgotten]]. The ''[[Transformers]]'' letter column even asked fans to please ignore the earlier Marvel crossover stories.

** A recent company crossover between IDW and Marvel did have the Avengers and Autobots team up. It's considered ambiguously canon by IDW.

* The original Mirage ''[[Teenage Mutant Ninja Turtles Mirage]]'' have crossed over with several other indy comic book characters, most notably [[Usagi Yojimbo|Miyamoto Usagi]], [[Cerebus]], the [[Wild West C.O.W.-Boys of Moo Mesa|Wild West Cowboys of Moo Mesa]], and [[Savage Dragon]].

** Playmates' TMNT toy line even had a [[Usagi Yojimbo|Miyamoto Usagi]] action figure at one point.

** Not to mention Usagi's appearance in several episodes of both TMNT cartoons.

** They also showed up in ''[[Turtles Forever]]'', crossing over with both TMNT cartoons.

* The [[Fantastic Four (Comic Book)|Fantastic Four]] piloted [[Combattler V]] once.

** To be accurate, this was when Marvel was publishing a ''Shogun Warriors'' comic book under license from Mattel, who released several Japanese [[Giant Robot]] toys under the banner. The Warriors were fully integrated members of the Marvel 616 universe.

* ''[[Star Trek]] / [[X-Men]]''

* ''[[The League of Extraordinary Gentlemen]]'' series by [[Alan Moore]] runs off this principle -- that all of fiction exists. So you get [[King Solomon's Mines|Allan Quatermain]] teaming up with [[Twenty Thousand Leagues Under the Sea|Captain Nemo]], [[Dracula (novel)|Mina Murray]], [[The Strange Case of Dr. Jekyll and Mr. Hyde|Dr. Jekyll & Mr. Hyde]], and [[The Invisible Man (novel)|Dr. Hawley Griffin]]. Then you get characters like Mycroft and [[Sherlock Holmes]], Professor Moriarty, [[James Bond (novel)|James Bond]], Edward Prendrick of ''[[The Island of Doctor Moreau]]'', the Martians from ''[[The War of the Worlds]]'', [[Alice in Wonderland]], [[Mary Poppins]], an unnamed Dr. Fu Manchu, and just about the entire litany of late-19th century to mid-20th century fiction showing up. There are books out that detail all of the references Moore crams in there.

* ''Marvel Team-Up'' #74 (October 1978) teams Spider-Man with [[Saturday Night Live|The Not Ready For Prime-Time Players]] to fight Silver Samurai after [[John Belushi]] accidentally gets Silver Samurai's ring.

** In a similar vein, ''[[The Avengers (Comic Book)|The Avengers]]'' once appeared on ''[[David Letterman|Late Night With David Letterman]]''.

** The ongoing crossover series by the same author called ''[[Dead Fantasy]]'', consists primarily of stunt-laden over-the-top battles between characters from ''[[Dead or Alive]]'', ''[[Final Fantasy]]'', ''[[Ninja Gaiden]]'', and ''[[Kingdom Hearts]]''.

* Anything by [http://www.fanfiction.net/u/1044838/ Ten-faced Paladin] that isn't an [[Alternate Universe Fic]] is a crossover (sadly, a couple of them are [[Dead Fic]]).

* There's a ''[[Sonic the Hedgehog]]''/''[[The Mighty Ducks (animation)|Mighty Ducks]]'' crossover (no, seriously) [http://www.fanfiction.net/s/6217246/1/Sonics_Trip_to_Anaheim here] which definitely qualifies, while also doubling as an [[Original Flavour]] story.

* ''[[The Princess Bride (film)|The Princess Bride]]'' which featured Harry as [[You Killed My Father|Inigo]], Hermione as Buttercup, and Dumbledore as the omniscient dream narrator who broke the [[No Fourth Wall|fourth wall]] repeatedly.

* [http://www.furryconflict.com/ ''Trek Wars: The Furry Conflict''] not only has one of the worst names in fiction, but is also one of the best and [[Schedule Slip|longest running]] [[Star Wars]] vs. [[Star Trek]] crossovers out there, having been started in 1996 and continuing to this day. Several things set TFC apart from the rest are that (a) all the characters are [[Rubber Forehead Aliens|furries]] with [[Starfish Aliens|few exceptions]], (b) [[Sliding Scale of Idealism Versus Cynicism|the ST universe turned out a lot better then canon w* hile the SW universe took a decided turn for the worse]], (c) the whole script is played out in a [[Role Playing Game|roleplay]] then transcribed to the net, and (d) none of the main characters from either franchise get more then a passing mention. In other words: it's a self-described [[Dramatic Parody]] that does a fairly good job of meshing the two universes, thanks to a big fat [[Negative Space Wedgie]]. [http://www.furryconflict.com/galactopedia/index.php/Main_Page It even has it's own wiki]!

* An early ''[[Star Trek]]'' fanfic (created after Season 2) crossed over with ''[[The Muppet Show]]'' with the excuse that Doctor Bob (Rowlf) was the ship's new doctor. [http://www.st-minutiae.com/humor/muppets.html Read the resulting hilarity here.]

* ''[[Both Syllables]]'' is a fairly well-known crossover between ''[[Invader Zim]], [[Buzz Lightyear of Star Command]]'', and ''[[Lilo and Stitch: The Series|Lilo and Stitch The Series]].''

* An online fanfic crossover between ''[[Star Trek: The Next Generation|Star Trek the Next Generation]]'' and ''[[Babylon 5]]'' contained a scene where Data turned to Captain Picard and said "sir, we appear to be in a universe where we are expected to obey the laws of physics".

* There's been a few ''[[Zero no Tsukaima]]'' stories on fanfiction.net where Louise instead summons a different familiar from another series. So far we've had [http://www.fanfiction.net/s/3703802/1/The_Alchemist_of_Zero Edward Elric] from ''[[Fullmetal Alchemist]]'', [http://www.fanfiction.net/s/5285567/1/Tsukaima_no_Chrono Chrono Harlaown] from ''[[Magical Girl Lyrical Nanoha]]'' and [http://www.fanfiction.net/s/4784134/1/Zeros_Dinobot Grimlock] from ''[[Transformers Generation 1]]''.

** And Shirou EMIya (partial caps intentional) of [[Fate/stay night]] in [[The Hill of Swords]].

* There is an obscure [[The X-Files|X-Files]] and [[Mystery Science Theater 3000|MST3k]] fanfic called [http://www.fortunecity.com/lavendar/pimlico/131/project.html The Project] (link leads to a [[MST|MST-ing]] of the fanfic). While the plot is rather generic for an X-Files fanfic, the real [[Narm|charm]] of it comes from the fact that the author seems to have seen about five minutes of MST3k, leading to [[Emo|Joel being emo]], having people [[Refuge in Audacity|die from watching bad movies]] and {{spoiler|Dr. Forrester [[Took a Level In Badass]] and kills Joel}}; it's absolutely hilarious.

* ''The Doctor and the Enterprise'', a Crossover [[Fanfic]] that predates the Internet, was eventually published with the ''[[Star Trek]]'' and ''[[Doctor Who]]'' serial numbers filed off.

* The ''[[Sin City]]'' and ''[[Batman]]'' fanfic called [[A Dark Knight Over Sin City]].

* ''[[Battlestar Galactica Reimagined]]'' and ''[[BattleTech]]'' crossovers have a bit of popularity due to the similarity of their FTL systems.

* [[Connecting the Dots|"Connecting the Dots."]], a intercontinuity crossover between the [[Justice League of America]] and [[Naruto]], along with a few thousand random cultural references. Think Superman fighting Naruto.

'''Beast and Bones:''' [[Name's the Same|Yes?]] }}

** [[Atop the Fourth Wall|Ladies and gentleman, the entire comic was leading up to that. That was the whole reason for this thing.]]

*** This is made even funnier by the realisation that the book was published over a year before ''[[X-Men 1]]'' was filmed. There are apparently very few charismatic bald actors to go round...

* Diane Duane is a ''[[Doctor Who]]'' fan, and as a result the Doctor (in different incarnations) has appeared in both her [[Young Wizards]] series and in one of her [[Star Trek]] novels.

* Since [[Discworld|L-Space]] means that libraries of sufficient size and/or complexity are interconnected, it's entirely possible for a crossover with anything. One wonders whether Havelock Vetinari and [[Girl Genius|Klaus Wulfenbach]] would get along...

* The basic concept of the ''[[Thursday Next]]'' books is that all novels are connected through the Bookworld, and Thursday can travel to them. For obvious reasons, the books Thursday enters are mostly [[Public Domain Character|public domain]], but the cast of [[Enid Blyton]]'s ''Shadow The Sheepdog'', Beatrix Potter's Mrs Tiggywinkle and Kathy Reichs' [[Bones|Temperance Brennan]] have all appeared with permission. (Of the estates in the first two cases, obviously.)

** The ''[[Doctor Who]]''/''[[Eastenders]]'' crossover (of very dubious quality, but it was for charity) ''Dimensions in Time'' could also be mentioned, although it's [[Fake Crossover|actually not in either of the shows' continuities]] (and indeed, since then they've [[Mutually Fictional|both featured each other as fictional programmes]]).

** The ''Kaldor City'' [[Doctor Who Expanded Universe]] audio dramas written by Chris Boucher and produced by Magic Bullet are set in the titular city from the ''[[Doctor Who]]'' story ''The Robots of Death'' (also by Boucher), but feature Scott Fredericks reprising the role of Psychostrategist Carnell from the ''[[Blake's Seven|Blakes Seven]]'' story "Weapon" (also by Boucher). The ''A History'' by Lance Parkin (an un-official history of the [[Whoniverse]]) makes a valiant attempt to claim that ''B7'' may well be set in the [[Whoniverse]], but really it's probably best to assume he's an [[Alternate Universe]] counterpart. Or just [[MST3K Mantra|don't worry about it]]. (There's also a cynical manipulator played by Paul "Avon" Darrow, who knows more about Carnell's Federation background than the Kaldorians, but let's not even get started on that...)

** Marvel also linked ''Doctor Who'' with ''[[Transformers]]'', by way of bounty hunter (sorry, "freelance peacekeeping agent") Death's Head. This is a borderline case, however, as the linkage only occurred when Death's Head fell through a dimensional rift from the Marvel UK ''[[Transformers]]'' universe and ran into the Doctor as a result.

*** In a more solid (possibly) example, the obscure character Octus has been stated to have a Dalek altmode. He was never seen transformed, but [[Word of God]] says that's what he turned into.

* It appears that the soap opera ''[[Passions]]'' has set itself up as a sequel of sorts to the classic [[Fantastic Comedy]] ''[[Bewitched]]''. It features Juliet Mills as Tabitha Lennox, a genuine witch whose daughter is named Endora and whose parents are a mortal named Darrin and a witch named Samantha. Furthermore, Bernard Fox has made two appearances on the show as his ''Bewitched'' character, Dr. Bombay.

* The ''[[Power Rangers in Space]]'' encountered the five Turtles from ''[[Ninja Turtles: The Next Mutation|TMNT: The Next Mutation]]''... but, uh, [[Fanon Discontinuity|we don't like to talk about the latter group around here]] ([[Canon Discontinuity|and neither do Eastman and Laird]]).

** On the other side of the Pacific, the world of the ''[[Samurai Sentai Shinkenger]]'' had an unexpected visitor in ''[[Kamen Rider Decade]]''. The crossover is in continuity for both shows; in fact, the fact that the ''Shinkenger'' world is the only world in ''Decade'' that is the genuine, canonical universe of the show in question rather than an [[Alternate Universe]] (original worlds aside) is a plot point for the arc. <ref>Speaking of which, ''[[Power Rangers]]'' already beat ''[[Super Sentai]]'' at a ''[[Kamen Rider]]'' crossover long ago with ''[[Mighty Morphin Power Rangers]]''' [[Poorly-Disguised Pilot]] for ''[[Masked Rider]]''.</ref>

*** The upcoming special ''Super Hero Wars: Kamen Rider vs. Super Sentai'' will be bringing together 240 heroes across both franchises, and once again [[Kamen Rider Decade|Decade]] is involved.

* The ''[[Friends]]'' episode "The One With Two Parts" introduces Phoebe's twin sister Ursula, who was a character on ''[[Mad About You]]''. Both had been played by Lisa Kudrow, so it was an obvious choice (to the network, at least) to make the previously unrelated characters twins. That same episode had Jamie and Fran from ''Mad'' mistake Phoebe for Ursula.

*** ''[[Martial Law]]'' also had a crossover with ''[[Walker, Texas Ranger]]''. The first episode takes place on Martial Law and begins with the characters standing in their station discussing a recent crime. Then a voice rings out from off-screen, saying "I hear you could use some help." And then the camera shifts to a pair of cowboy boots and slowly pans up to reveal Ranger Cordell Walker, illuminated by a bare lightbulb overhead like some pagan godling. Then he and Sammo team up to stop violent, genocidal white supremacist militia members attempting to steal chemical weapons to use to ethnically cleanse Los Angeles.

**** This is followed by an episode of ''[[Walker, Texas Ranger]]'' where Sammo visits Texas to help finish up the case. Sammo's extra-sensory and clairvoyant Chinese Daoist powers are accepted by the Rangers without a word of doubt. As Walker's long-suffering partner Trivette explains, "Around here, we call that sort of thing "Cherokee."

* Despite concepts seemingly custom-made for crossovers, ''[[JAG]]'' and ''[[NCIS]]'' only crossed over for one two-parter. Though NCIS didn't exist as a separate show when the crossover happened. In other words, a [[Poorly-Disguised Pilot]].

* It's not quite ''Archie Meets The Punisher'' bizarre, but the special ''Alice'' two-parter that featured a visit from Boss Hogg, Roscoe and Enos from ''[[The Dukes of Hazzard]]'' (Boss Hogg was <s>Not-Flo</s> Joleene's cousin) is up there.

* ITV drama series ''Footballers' Wives'' briefly exported popular character Tanya Turner to ''Bad Girls'' (also produced by ITV) when Tanya was jailed during the plot.

** Also, the {{spoiler|big "cork" on the bottle of evil}} at the end of the show pretty closely resembles {{spoiler|a [[Buffy the Vampire Slayer|Hellmouth]].}} Probably not intentional, but wouldn't it explain just about ''everything''?

* Speaking of ''[[Lost]]'', one of Chef Robert Irvine's missions on ''[[Dinner Impossible]]'' was to cook for the cast of ''[[Lost]]''. Though it was clear to everyone that ''[[Lost]]'' is only a television show, Nestor Carbonell did appear in character as Richard Alpert and Robert was given several Dharma food drops to work with, so it qualifies somewhat for this trope.

* ''[[Crossing Jordan]]'' and ''[[Las Vegas]]'' crossed over so often that it probably doesn't even qualify as [[Intercontinuity Crossover]]. They certainly take place far enough apart geographically that it's plausible that they're within the same continuity. I think that the ''[[Crossing Jordan]]'' characters made one more appearance in ''[[Las Vegas]]'' after their own show had been canceled, though both shows are now finished.

** In one LV episode, Mary made a reference to booking a conference room for [[The Office|Dunder-Mifflin]], and ''[[Heroes (TV series)|Heroes]]'' and the 2008 ''[[Knight Rider]]'' series have both made references. Linderman being involved would certainly explain the Montecito's high owner turnover rate. Don't combine it with the ''[[Lost]]'' bit above, though, or your head might explode.

* ''[[Fringe]]'' has a particularly interesting example of this trope. The Observer, or rather {{spoiler|one of them, specifically September}}, whose task it is to police inter-dimensional travel and interferences with the timeline, has managed to crossover from the ''Fringe'' continuity... into the "real world". He appeared in the audience of ''[[American Idol]]'' and has been spotted in various stadiums during Fox sports broadcasts.

** It's unclear whether the fact that Fringe Division's job used to be called [[The X-Files|the "X-Designation"]] is this or a [[Shout-Out]].

* An episode of ''[[Warehouse 13]]'' included [[Butt Monkey|Douglas Fargo]] of ''[[Eureka]]''.

** And an episode of ''Eureka'' included Claudia Donovan from ''Warehouse 13''.

* [[R. Lee Ermey]] turned up in Season 1 Episode 4 of ''[[Pawn Stars]]'' in full ''Lock n' Load'' gear.

* ''[[Ally McBeal]]'' and ''[[The Practice]]'' had a two-part crossover special that started on ''[[Ally McBeal]]'' on Fox and was resolved in the next hour on ''[[The Practice]]'' on ABC, with several characters from each show appearing on the other show. Both shows were produced by David E. Kelley.

** 1997's ''[[Prime Suspect]] [[Cracker]]'', in which Fitz and DCI Tennyson hook up and decide that now they have a relationship they don't ''care'' who the killer is.

** 1997 also had ''[[Ballykissangel]][[The Vicar of Dibley|Dibley]]'', in which Geraldine desperately tried to convince a visiting Father Peter that her parishioners were normal.

* When [[Hulk Hogan]]'s first movie, ''No Holds Barred'', hit theaters, the [[WWE|WWF]] thought it'd be a good idea to bring in the villain of the film, [http://www.thewrestlinglegendsforum.com/wrestlecrap/zeus.html Zeus], to battle Hulk in a WWF ring. They were never really clear on whether this was supposed to be the movie character come to life, or the actor assuming the character's persona to wreak havoc (in some promos, he'd lean one way, in others, the other), but one thing was absolutely clear throughout the entire angle: it was [[Wrestlecrap]].

* [[RoboCop]] (yes, RoboCop!) appeared at [[WCW]]'s ''Capital Combat 1990'' to rescue [[Sting (wrestling)|Sting]] from a cage he was placed in by the Four Horsemen.

== Toys ==

* Matt Trakker of ''[[MASK]]'' recently re-emerged as an action figure in the ''[[G.I. Joe]]'' line, presumably because Kenner (''[[MASK]]'''s manufacturer) merged with Hasbro (''[[G.I. Joe]]'''s manufacturer) years ago.

** And don't forget G.I.Joe's original [[Intercontinuity Crossover]] character, [[WWE|WWF]] wrestler Sgt. Slaughter.

** Hasbro has also done ''G.I. Joe'' action figures for [[Rocky (film)|Rocky]] Balboa and William "The Refrigerator" Perry as team trainers.

* ''[[Garry's Mod|Garrys Mod]]'' allows you to do all kinds of crossovers with the right mods. Want [[Halo (series)|John-117]] to team up with [[Half-Life (series)|Gordon Freeman]] and fight [[Mass Effect|Saren]]? Have fun.

* ''[[Mario and Sonic At The Olympic Games]]'' featured the first meeting of [[Super Mario Bros.|Mario]] and [[Sonic the Hedgehog]]. Since the pair were the mascots of former [[Console Wars|warring console makers]] [[Nintendo]] and [[Sega]] (respectively), [[Cue the Flying Pigs|this was something of a big deal for old-school gamers.]]

* ''Mario Hoops 3-on-3'' and ''[[Mario Sports Mix]]'' add ''[[Final Fantasy]]'' characters to the traditional cast of Mario sports games.

* The ''[[Itadaki Street|Fortune Street]]'' series eventually added ''[[Dragon Quest]]'' characters to the game. Sony installments of the series crossed them over with ''[[Final Fantasy]]'' characters, while the Wii and DS installments mixed them up with the ''[[Super Mario Bros.]]'' cast.

* ''[[Wario Land]] Blast: Featuring [[Bomberman]]!'' which is pretty much what the title says. (Except in Japan, where it was ''GB Bomberman'' and had nothing to do with Wario.)

** The ending of ''[[Bomberman]]'' for the NES had Bomberman turning into the player character from [[Hudson Soft]]'s NES version of ''[[Lode Runner]]''.

** For that matters, the ''[[Super Robot Wars]]'' series itself is ''built'' on the idea of [[Mazinger Z]] and Shinji Ikari teaming up to beat up Char Aznable.

* ''[[Mortal Kombat vs. DC Universe]]''.

** And in ''[[Mortal Kombat 9]]'' DLC, vs [[A Nightmare On Elm Street 2010|Freddy Krueger]].

* DJ Atomica, the (some would say) [[Dumbass DJ|annoying announcer]] in ''[[Burnout]] Paradise,'' is the same guy who provided the commentary for ''SSX 3''. In ''Paradise,'' he makes reference to ''SSX'' several times, suggesting it's supposed to be the same character.

* A couple of recent ''[[Yes! Pretty Cure 5|Yes! Pretty Cure 5GoGo!]]'' video games have incorporated characters from the [[Futari wa Pretty Cure|previous]] [[Futari wa Pretty Cure Splash Star|universes]]. The story implications of the ''[[The Idolmaster (video game)|iDOLM@STER]]'' knockoff are probably not significant, but the DS game has a plot suggesting they all share a universe and simply never ran into each other before (which does happen in the ''[[Pretty Cure]] All Stars DX'' movie).

* ''Super Puzzle Fighter II Turbo'' has characters from ''[[Street Fighter]], [[Darkstalkers]],'' and ''[[Cyberbots: Full Metal Madness|Cyberbots]]''. There's only one character from the latter, though.

* [[Capcom]]'s [[Capcom Versus Whatever|"Vs. series"]] started life as such with ''[[X-Men vs. Street Fighter]]'' and ''[[Marvel Super Heroes vs. Street Fighter]]'' before stepping into [[Massive Multiplayer Crossover]] territory; it hasn't looked back since.

* ''[[Kingdom Hearts]]'' is a crossover between [[Disney]] and ''[[Final Fantasy]]''.

* ''[[My World, My Way]]'' features two characters, the mysterious dungeon diggers Owen and Kate, who were the protagonists of a previous [[Atlus]]/Global A game entitled ''Master of the Monster Lair''. Owen even carries around the magic shovel that he had in ''Monster Lair'', and the dungeon layouts are similar in both games.

* [[Telltale Games]]'s latest game, ''[[Poker Night At the Inventory]]'', features Tycho Brahe, Max, Heavy Weapons Guy, and Strong Bad, from ''[[Penny Arcade (Webcomic)|Penny Arcade]]'', ''[[The Adventures of Sam & Max: Freelance Police|Sam and Max Freelance Police]]'', ''[[Team Fortress 2]]'', and ''[[Homestar Runner]]'', respectively, all playing poker together, plus an assortment of characters milling around the background. Plus, it could theoretically cross over with just about any property that's ever had a game made of it, period.

* Interesting crossover here, in ''[[Devil May Cry]]''. Dante receives the sword named Alastor, imbued with an electrical motif. Later on in ''[[Viewtiful Joe]]'', a character named Alastor appears, complete with the electrical motif. The connection is later made in the [[PlayStation 2|PS2]] port of ''Viewtiful Joe'' in which Dante guest stars and Alastor harbors some unfriendly feelings towards Dante.

** After this, the connection is pushed forward in [[Tatsunokovs Capcom|Tatsunoko vs. Capcom]] in which Morrigan's win quote vs. Viewtiful Joe mentions that she was disappointed in him after talking to Alastor. Leading to an implication that ''[[Darkstalkers]], Devil May Cry'', and ''Viewtiful Joe'' are all part of the same universe.

== Web Comic ==

** Now has a sequel called [http://www.drunkduck.com/Crossoverkill/index.php?p=752922 Crossoverkill]

* Unwinder of ''[[Unwinder's Tall Comics|Unwinders Tall Comics]]'' adopted ''[[Marmaduke (comic strip)|Marmaduke]]''. Then, in the ''[[Watchmen (comics)|Watchmen]]'' parody comic, the big dog dies à la Jon Osterman. According to the author, "It's not ''Tall Comics'' canon, but it IS ''Marmaduke'' canon."

* ''[http://www.whiteponyproductions.com/comicstrips/ctc/present.htm Cross Time Cafe]'': Characters from at least five different webcomics are regular cast members - though half the cast appears more here than in their own comics (the main exceptions being [[Freefall|Florence]], [[21st Century Fox (webcomic)|Jack and Jenny]].

* ''[[Something Positive]]'' is practically some sort of [[Massive Multiplayer Crossover]] nexus of webcomics. (See that article for more.)

== Web Original ==

* ''[http://www.starwreck.com/ Star Wreck: In The Pirkinning]'', a Finnish ''[[Babylon 5]]''/''[[Star Trek]]'' crossover movie that took seven ''years'' to make. So good, it's apparently the most-watched Finnish film, and Universal Studios are distributing an updated version.

* ''[[I'm a Marvel And I'm a DC]]'' has Marvel and DC characters (and occasionally characters from other continuities, such as ''[[Hellboy (comics)|Hellboy]]'') arguing with each other about whose comics and movies are best. Then there's the "After Hours" series which has actual storylines involving characters from both continuities, in the same vein as the official Marvel/DC crossovers.

* [[Dragon Ball Abridged|Ghost Nappa]] has been in a [[Yu-Gi-Oh!: The Abridged Series|duel]], [[Vision of Escaflowne Abridged|Atlantis]] and [[Lanipator]] and Kaiser Neko's hotel room.

** And the fact that, by extension, ''[[American Dragon Jake Long]]'' is set in the same universe as ''[[Lilo and Stitch (Disney film)|Liloand Stitch]]'', ''[[Kim Possible]]'', and ''[[Recess]]'' has lots of strange implications...

** It's ''very'' confusing with ''[[Recess]]'', as it's made explicitly clear in the series that it takes place over the course of the Fall of 1997 until the Summer of 1998 (and then Fall 1998 for ''Recess: Taking the Fifth Grade''), even for the episodes made in the 2000s (this is firmly established in ''[[Recess: School's Out|Recess Schools Out]]'')

** The episode name, for the curious, is ''The Green Loontern''. And in another episode (''Samurai Quack'') Dodgers takes the place of [[Samurai Jack]]. Complete with <s>Aku</s> Achoo, voiced by Mako himself.

* On ''[[The Simpsons (animation)|The Simpsons]],'' Homer's claim to having had a close encounter with an extraterrestrial is investigated by none other than [[The X-Files|Agents Scully and Mulder]].

** [[Cheers|"Just gimme another beer, you braindead hick! I'll kill you! I'll kill all of you!"]]

** [[Dragnet|"Gee, Joe. You haven't been the same since your son went crazy in Vietnam"]]

** There were also plans to do a crossover when it seemed there would be a series version of ''[[Atlantis: The Lost Empire|Atlantis the Lost Empire]]'', called ''Team Atlantis.'' Set in the '20's, it would have involved the ''Atlantis'' cast getting involved in a battle between Demona and a former Hunter.

* In an ad for ''[[Metalocalypse]]'', [[Brütal Legend|Eddie Riggs]] apparently served a stint as a roadie for Dethklok.
