Massive Multiplayer Crossover
"So many heroes from so many dimensions! This is pretty cool!"A crossover that involves characters from more than two works of ficton. More often than not, this is a mash up of series which do not have a strict sense of continuity or a clear Universe Bible. To lessen canon-faulting, especially with series that do have strict continuity, a new 'neutral' setting is made that offers equal footing for all the characters. It also becomes more viable the farther you get from canon, such as one-time TV specials and especially video games. As Story Arcs have become more prevalent, this practice has somewhat lessened, with shifts to strict Verse building and explicit references. This rarely occurs in live action shows, unless a production company can be formed that holds copyrights to everything. Thus, this is much more common in animated works — although you can generally expect The BBC to pull one out of somewhere when Children in Need or Comic Relief rolls around. This trope has become increasingly common in video games, especially those involving both licensed and original properties. These games, depending on how far or how deep they mine, can have interesting effects on the fiction chosen. Many long-gone and/or forgotten Humongous Mecha shows, for example, often get a new lease on life, or even a brand-new sequel or remake, after making an appearance or two in a Super Robot Wars game. Similarly, the Fire Emblem series was finally brought over to the US to great success after two of its characters made an appearance as unlockable fighters in Super Smash Bros. Melee. This trope is Older Than Feudalism. The Argonautica by Apollonius Rhodius (3rd century BCE) features nearly every ancient Greek mythical hero all going on a quest to find the Golden Fleece. Sub Tropes:
- Crisis Crossover (a company-wide Massive Multiplayer Crossover)
- Cross Through (a company-wide event that affects every series involved without having them cross over)
- Deconstruction Crossover (when the main purpose of using a Massive Multiplayer Crossover is Deconstruction)
- Monster Mash (classical movie monsters)
- Ultimate Showdown of Ultimate Destiny (When the Massive Multiplayer Crossover meets Let's You and Him Fight)

Anime & Manga
- The Giant Robo OVA series featured characters taken from several other series Misuteru Yokoyama — the original creator of Giant Robo/Johnny Sokko and His Flying Robot — had written.

Then there was X/1999 where characters from past CLAMP series started appearing, including Subaru, the main character of Tokyo Babylon, as a major character, and during his series set in the early 90s it was said that he would have a role in The End of the World as We Know It that is X, making for a bit of foreshadowing.

- While most Go Nagai series contain cameos here and there, Shin Mazinger goes the whole way. Characters from several alternate versions of Mazinger Z show up, as well as characters from Violence Jack (itself a Deconstruction Crossover) and the title demon from Mao Dante. Unsurprisingly, this series is being directed by the same man behind Giant Robo, Yasuhiro Imagawa.

- A non-canon Judge Dredd story in the 1980 Dan Dare annual had Tharg bring all the popular characters currently being published in 2000 AD as well as the Starlord to Dredd's apartment for a surprise party.

- Many Seltzer and Friedberg works, such as Epic Movie and Disaster Movie, could be considered Massive Multiplayer Crossovers, insofar as they feature many characters and plot elements (or weak parodies thereof) from recent movies and mash them all together. By all rights, this really should produce something worth watching on some level.
- A version of this in Star Trek: Generations, which featured the captains of two Enterprises from completely different eras (Kirk and Picard) in the same film. Star Trek has done this numerous times, if you consider the different series separate entities of the same intellectual property.

Mythology and Religion
- The Argonautica (more commonly known by the adaptation Jason and the Argonauts) by Apollonius of Rhodes (3rd century BCE) is one of the very first Massive Multiplayer Crossovers, arranged in what would become a fairly classic method — basically throwing one or two dozen heroes from various separate Greek myth cycles together on a boat with a common mission. This of course makes the Massive Multiplayer Crossover Older Than Feudalism.
- Many of the same characters also appear in the story of the Kalydonian Boar Hunt - which, Depending on the Author, may occur before or after The Argonautica.
- According to some religious studies texts, this has also gone on in many, many other myths: the most notable involve various saints meeting each other. This goes on even today.
- The Machinima Beans. Firstly, it crosses over characters from three different series and is made by three different machinima directors, then the storyline involves various internet memes... Oh. And it's made on Super Smash Bros.. Making it a crossover on a crossover.
- Technically, any community-made Machinima will have this in spades. Want to see Duke Nukem appear together with some Daleks? It's been done.
- Heroes and Monsters of the Milennium Is a conversion for the Unisystem RPG ruleset, mixing Buffy the Vampire Slayer/Angel with everything from Marvel and DC Comics to Stargate SG-1, Godzilla, Ultraman, Lyrical Nanoha, Gargoyles, Mahou Sensei Negima!, the works of HP Lovecraft, Mazinger Z and many others. With considerable overlap in themes, races, and technology.

- TV Tropes has one for the works of the Walt Disney Company called Friends And The High Council.
- Dramatic Dream Team (basically a parody of American wrestling), Pro Wrestling NOAH (American style matches only with a more realistic take and a more formal presentation), Pro Wrestling Zero 1 (even more emphasis on technical matches than NOAH but have tendencies toward exaggerated gimmicks and bizarre angels), Michinoku Pro Wrestling (largely based on Mexican Lucha Libre though there are some "Japanese strong style" staples) and IWA Japan (features "hardcore" wrestlers and has a strong Puerto Rican Lucha Libre influence) all got together to do a show, which was as odd and entertaining as that many collaborating together sounds could be.

- The BBC Radio 4 series The Rivals is a series of adaptations of various Victorian detective stories by people who weren't Arthur Conan Doyle, based on the short story collections The Rivals of Sherlock Holmes edited by Hugh Green. What makes the radio series a Massive Multiplayer Crossover rather than a sequence of unrelated dramas is that Inspector Lestrade is added to every story as The Watson, placing them all in the same Verse.
- The Big Finish Doctor Who "Sixth Doctor and Jamie" series, which is set entirely in the Land of Fiction:
- Night's Black Agents is a Scottish Gothic fest, featuring Merodach from "The Brownie of the Black Haggs" by James Hogg, Lucy Ashton from The Bride of Lammermoor by Sir Walter Scott and Thrawn Janet from the Robert Louis Stevenson story of the same name.
- Legend of the Cybermen features the Artful Dodger, Little Lord Fauntleroy, Alice Liddel, Dracula,Long John Silver and Captain Nemo.

- The Fictional ISOT Map Game series of AlternateHistory.com takes its premise as being about 2-dozen or so nations from different works of fiction suddenly being transported to a "blank" Earth without sentient life.

- The Massive Multi-Fandom RPG, taking place right here on our own forums. Princess Tutu, Naruto, Pokémon, The Legend of Zelda, No More Heroes, and Discworld- and that's just for starters.
- Destroy The Godmodder : And how. Players can summon, as entities, anything from any fictional work to fight for them. This is the plot at the moment (in DTG 2):
- Minecraftia, the setting of the game, is threatened by the Godmodder, a mysterious employer who convinced Doc Scratch, Lord English, and the Condescence to invade it, and team of Well Intentioned Extremists known as the counter-operation that was set up my the U.S Government and is made up of an AI called Project Binary, GLaDOS, and Bill Cipher.
- The heroes consist of the insane king of the Nether accompanied by Midna, who wields the Twili version of the Master Sword, an elven mage who happens to be an alien from a Sburb session, a warrior-engineer from the Warhammer 40K universe, another elf, this time an engineer who is companions with an iconic drunken robot and owns a space station populated by a small army of kerbal researchers and run by HAL 9000.
Stand Up Comedy
- There's a Star Trek-related comedy routine in which Mr. Spock, HAL 9000, and Obi-Wan Kenobi all appear on Jeopardy, in a mental variant of an Ultimate Showdown of Ultimate Destiny. Kenobi is declared the winner, but only because he uses the Jedi Mind Trick on Alex Trebek.
- Stand-up comedy troupes sometimes feature a series of comedians who usually headline their own shows:
- The Original Kings of Comedy
- The Blue Collar Comedy Tour
- The Comedians of Comedy
- The Spelljammer and Planescape settings were designed with this in mind. Spelljammer in particular has rule books dedicated to detailing the Crystal Spheres of settings such as Krynn, Abeir-Toril, and Oerth. Where as Planescape has portals to every type of world imaginable.
- Collectible Card Games that operate off of a Universal System allow for this; the Universal Fighting System lets you pit Chun-Li against Nightmare, the VS System crosses over Marvel Comics and DC Comics, and the Crusade System lets you pair Spike Spiegel, Edward Elric, and Cutey Honey with Humongous Mecha from Macross, Super Robot Wars Original Generation, and countless others.
- Similarly, the Hero Clix tactical miniature combat game works on a Point Build System basis and includes characters from many comic books (Marvel and DC, but also "indie" ones); Superman, Dhalsim and Dark Phoenix against Dr. Manhattan, Beta Ray Bill and someone else to match character points is a perfectly reasonable battle.
- Ani-Mayhem, a Collectible Card Game produced in the middle 1990s by Pioneer Entertainment that set characters from many different anime settings — surprisingly including many series licensed by companies other than Pioneer — in a grand romp across their various worlds.
- Seussical has characters from several of Dr. Seuss' books
- The Game in which Life In A Game takes place seems to take all video games as true, with Zelda appearing alongside Master Chief, and Frog serving as the hero's Jerkass Mentor.
- That Guy with the Glasses
Ask That Guy: (speaking to the various reviewers present) In fact, I think there's a lot of you who want to do crossovers, aren't there? Because everybody really eats that shit up.
- The one year anniversary video. Basically, in a Chicago hotel 20 contributors of Video Review Shows beat up one another in an Ultimate Showdown of Ultimate Destiny, climaxing in Super Mega Death Christ vs. Giant Robotic Donkey Kong Jesus riding a puff of smoke blowing up. You know what? Just watch it.
- All the cast stayed in Chicago for a couple more days to film crossovers after this. Highlights include Linkara being force-read his own Massive Multiplayer Crossover fanfiction by the Sage, the Ultimate Warrior writes a comic series so bad that reality breaks down and Linkara and Spoony keep changing into different Alternate Universe selves and the Critic and Nerd joining forces to review... a Making Of of a Teenage Mutant Ninja Turtles Tour. Yeah.
- Later on when faced with Uwe Boll's Alone in the Dark (2005), the Nostalgia Critic gave up on reviewing it. Until! Spoony and Linkara arrived to assist him.
- 2010 kicked off with an epic review of Dragon Ball Evolution, starring Paw, LordKat, Rollo T, Hopewithinchaos, and Y Ruler of Time, with guests including LittleKuriboh, MasakoX and The Happy Video Game Nerd. This was recorded while everyone was attending MAGFest.
- The Two Year Anniversary is another huge crossover event. And in turn, it allowed some once-in-a-lifetime crossovers as by this point, quite a few reviewers are from around the world.
- In 2011, things repeated. Y Ruler of Time used MAGFest to do another multiple reviewer crossover (The Last Airbender, with Todd in the Shadows, JesuOtaku and RolloT, plus various cameos). And Year Three had a crossover series and various individual joint reviews (Todd even opens his one saying that the trip means crossovers... and gets shot down by three people before Film Brain accepts to watch a movie with him).
- And once again in 2012. However, this time it was Linkara that used MAGFest for a multi-reviewer crossover (Southland Tales), and Year Four had a mini series that's a sequel to the previous one and more individual crossover videos.
- The original The Ultimate Showdown of Ultimate Destiny flash video. Good guys; bad guys; explosions as far as the eye can see. Way too many pop culture icons to count.
- Symphony Of The Blood, a fake video game crossover between all the characters of the Star System of Osamu Tezuka.
- The Slender Man Mythos stories tends to have the blogs mix together. For example, M of The Tutorial regularly participates in Damien's blog, Dreams in Darkness.

- John C. Wright has come up with a campaign setting (further down the page) which revolves around "anything goes", and incorporates roughly a billion various setting and universes into one complex setting rife with secret societies and inter-universal conflicts.
- Warp Zone Project happens in a world where all fiction is actually piece of earth's true history, which implies this trope coming into play.
- Disney owns all the characters it uses plus a whole network. House of Mouse has Mickey and Co. as hosts of a nightclub/theater, with the characters of the feature films as the audience.
- Many classic Hanna-Barbera characters have been used across the board, in shows like Laff-A-Lympics and Yogi's Gang; this is still done, but with a more satirical bent (e.g., Harvey Birdman, Attorney at Law). The largest gathering of characters, however, came with a Hanna-Barbera 50th anniversary special in 1989 as all the characters gather together to pay tribute. This doubles as Roger Rabbit Effect as they interact with Joe and Bill themselves, along with special hosts Tony Danza and Annie Potts.
- Another Hanna Barbera effort issued in 1981, Space Stars, featured a "Space Stars Finale" crossover at the end, where the coalitions from at least two of the segments — "Space Ghost," "The Herculoids," "Space Teens" and "Astro and the Space Mutts" — teamed up in the final segment to defeat the bad guys. Often, there were at least three of the coalitions, while at least once all four teamed up.
- Nearly all recent Warner Bros. animated television series made references and overt cameos with one another.
- The early-90s public service announcement Cartoon All-Stars to the Rescue had characters like the Teenage Mutant Ninja Turtles, The Smurfs, Winnie the Pooh, the cast of Ducktales, and many others team up to teach a single kid about the dangers of drugs and save his sister from same. Although, if you can see Smurfs, there's a good chance you're tripping balls already.
- The '80s cartoon Defenders of the Earth starred King Features' most famous adventure-hero characters: Flash Gordon, The Phantom, and Mandrake The Magician (along with his sidekick, the strongman Lothar).
- Much earlier, in 1972, the one-off animated special The Man Who Hated Laughter united all of King Features' popular characters — meaning not only Flash, the Phantom, Mandrake, and Lothar, but also the likes of Popeye, Blondie, Snuffy Smith, and Beetle Bailey.
- Captain N: The Game Master featured a mishmash of characters who appeared on the Nintendo Entertainment System done wrong. Most of the episodes took place in the neutral Videoland, with characters like Simon Belmont, Mega Man (Classic) and Pit hanging around, even if In Name Only. Link and Zelda from The Legend of Zelda (more accurately, from the Zelda cartoon) appeared too.
- The Children in Need music video "Peter Kay's Animated All-Star Band", which features nearly every significant British Stop Motion characters with a few 2D British and American characters broadcast "live via satellite", including Roary The Racing Car, Fifi And The Flowertots, The Wombles, In the Night Garden, Angelina Ballerina, Scooby-Doo, Bagpuss, Bob the Builder, Ben 10, Thunderbirds, Postman Pat, Spongebob Squarepants, Fireman Sam, Camberwick Green, and Paddington amongst others.
