Crisis Crossover - TV Tropes
- ️Thu Jun 14 2007
This is one way they can start.
"So first there was The Infinity Gauntlet, then Infinity War, and now there's Infinity Crusade. It must be like an annual convention for super heroes that Warlock runs for them. It gives them all a chance to get together and network and catch up on each other's continuity, exchange business and trading cards, pose for holograms with each other, stuff like that. They probably just wish the things were held in San Diego or someplace fun, where everyone could hang out at the beach."
— Marvel Year in Review 1993
A company-wide Massive Multiplayer Crossover which sweeps all the "mainstream" characters in a ficton into a single storyline and, often, takes their own series along for the ride.
The original was Marvel Comics's Secret Wars (1984), but the trend only really caught on with Crisis on Infinite Earths, the event which changed The DCU so much that its history is permanently defined as "pre-Crisis" and "Post-Crisis". It went from April 1985 to March 1986, tying in almost every other series DC Comics published at the time.
After this, it became more and more popular, with not just Marvel and DC but other companies — Malibu, WildStorm, etc. — getting into the act. Eventually, though, readers were sick of it, and it tapered off, before returning to the scene in 2004 when DC and Marvel both launched new Crisis Crossovers that started Metaplots that are still running today. Time will tell how long it takes for readers to get sick of it this time (if they aren't already).
The advantage of a Crisis Crossover to a publisher is that people reading the main story will want to read the various crossovers, thus increasing sales. The disadvantage is that people who only want to read one of the titles that cross over may be turned off by having to buy all the tie-ins to understand it, thus decreasing sales. In practice, it can go either way, but there's a reason the technique was abandoned for awhile.
In-story, the scope is usually more massive than what may be found in the stories at ongoing comics. Things like the death of a flagship character or events where Nothing Is the Same Anymore for the whole setting usually take place in those stories. But what about the event that kickstarts it all? It may simply take place in the first issue, it may be expanded in a dedicated one-shot (with titles such as "Crisis Alpha", "the road to Crisis", and "Prelude to Crisis"), or even have been brewing for quite some time already in a previous Comic Book Run elsewhere by the author. For example, Secret Wars (2015), King in Black and War of the Realms are the culmination of The Avengers (Jonathan Hickman), Venom (Donny Cates) and Thor (2014) respectively.
In comics, there are several subtypes:
- The classic is a single mini- or maxi-series, with other titles having a couple issues branded with the crossover's title. Crisis on Infinite Earths itself and Secret Wars II are of this type.
- A second kind is the all-annuals crossover. Many comic series have, in addition to their twelve monthly titles per year, a thirteenth plus-sized annual. An all-annuals crossover takes place entirely in one year's annuals (plus, perhaps, a special bookending issue or two). Armageddon 2001 and Atlantis Attacks! are examples.
- Fifth Week Events. Most comics come out monthly, most comics come out on Wednesday, and most months have four Wednesdays. Four times a year, however, there will be a month with a fifth Wednesday. Instead of moving titles around so that (for example) some comics that usually come out on the fourth Wednesday are pushed to the fifth, the publisher may just schedule an event for that week. Example: Sins of Youth
- Self-contained: A crossover that doesn't crossover. The heroes take a break from their own books to participate in a mini-series, then return to their own books. Examples: Secret Wars and Cosmic Odyssey.
- The opposite is the crossover without a self-titled mini-series; the whole crossover takes place in extant books. Marvel used to do this a lot, as with Inferno and Acts of Vengeance.
- The current format is an expansion of the first type: There will be a core series, one or more spinoff series, probably some one-shots, and crossover into regular titles. Blackest Night, for example, had a core mini-series, seven multi-issue spinoffs, a slew of one-shots (nominally numbered as "new" issues of long-dead series), and heavy crossover into both Green Lantern titles, among others.
When a comic slaps a big, visible "Crisis Crossover" logo on the cover, but only has a token Shout-Out to the Big Event that only peripherally affects the plot of the issue in question, that's a Red Skies Crossover. When a Crossover occurs that involves a couple of characters and their support, but doesn't necessarily affect the large universe, it's a Bat Family Crossover. When the various sets of characters do not interact with each other but still deal with a universal threat, it's a Cross Through. When the same characters from different Alternate Universes work/clash together in a Crisis Crossover, then it's an Intra-Franchise Crossover.

Anime and Manga
- The Pretty Cure Magical Girl metaseries have their own Crisis Crossover movie series labeled "Pretty Cure All Stars", featuring heroines from all series released until then.
- However, after quite a few All Star movies and too many heroes to work with, the franchise's Crisis Crossover movie series may be going in a new direction with its upcoming film, "Pretty Cure Dream Stars;" which feature only two Precure teams teaming up and possibly meeting a member of a new team.
- Then a canonical crossover happened in HuGtto! Pretty Cure when one of the villains froze time and all the Cures had to stop him.
- The 2nd part of the Time Bokan OVA in 1993 involves the Dorombo Gang from Yatterman invading a city populated by other Tatsunoko Production characters, and who should show to stop them but the Science Ninja Team Gatchaman, Casshern, Hurricane Polymar, and Tekkaman?
- Tsubasa -RESERVoir CHRoNiCLE- features characters, Spin-Offspring, Expys, and/or cameos from more or less everything CLAMP has ever written.
- The Majokko Club Yoningumi A-kūkan kara no Alien X OVA is a crossover between Studio Pierrot's most successful Magical Girl series. Creamy Mami, Magical Emi, Pastel Yumi, and Persia all team up to fight alien forces on the moon.
- Digimon Xros Wars: The Young Hunters Who Leapt Through Time has one in its final few episodes, which saw the return of all the leaders and various other members of all previous Digimon teams.
- Yu-Gi-Oh!: Bonds Beyond Time is one between the protagonists of the first three series. It's spawned a fair few fanfiction imitations as well.
- Invoked in-universe in Re:CREATORS, where in order to empower the Creations against Altair, the government formulates a plan to have their creators make a crossover event film in which the characters join forces to defeat Altair due to the fact that the Creations' power-ups rely on the general public to accept and embrace them. The final result is that Altair curb-stomps the whole lot of them because the audience loves her much more and a really twisted version of Only the Leads Get a Happy Ending, with Altair being "the lead" in question.
Fan Works
- Cap-Force is basically a Capcom version of Marvel Comics' The Infinity War. A mysterious and powerful entity has caused most of the Capcom multiverse to become dust which nearly caused The End of the World as We Know It. Heroes from most of Capcom's franchises (Street Fighter, Darkstalkers, Mega Man X, Resident Evil, Devil May Cry, Final Fight, Phoenix Wright: Ace Attorney, Dead Rising, Power Stone, Rival Schools, Captain Commando, Ōkami, etc.) are brought together to combat this threat and hopefully undo the damage done to the multiverse.
- Coreline involves a tremendous amount of characters from various fictional sources (DC and Marvel Comics and Anime such as Neon Genesis Evangelion and cartoons like Inspector Gadget, to give examples) trying to deal with an Earth that has become a bunch of universes struggling for room a la Convergence and Secret Wars (2015).

Until the Final Battle of the Dark World timeline, when Twilight uses her connection with Minty Pie and the temporal paradoxes created by Nightmare Eclipse's "Groundhog Day" Loop plan to summon the G1, G2, G3 and G4 (pre-Reign of Chaos) mane casts in order to use multiple sets of the Elements of Harmony to defeat Eclipse and her Psycho Ranger Co-Dragons.

Film — Live-Action
- DC Extended Universe:
- The climax of Batman v Superman: Dawn of Justice has Superman, Batman and Wonder Woman teaming up to stop Doomsday.
- Justice League has Batman, Wonder Woman, The Flash, Aquaman and Cyborg teaming up to prevent an invasion by the New Gods of Apokolips led by Steppenwolf on behalf of Darkseid.
- Disaster Movie can be seen as this, with various movies crossing over as the end of the world occurs.
- Godzilla has had several:
- Ghidorah, the Three-Headed Monster is a somewhat smaller-scale version of this. Mothra had already crossed over into the Godzilla universe in Mothra vs. Godzilla after having her own earlier film, but this one also adds Rodan, who had his own separate film, so that all three monsters could team up against King Ghidorah. This also started the tradition of eventually having all of Toho's various Kaiju showing up in this fused universe.
- Destroy All Monsters once again had Godzilla, Mothra and Rodan, but also added other Godzilla monsters like Anguirus, Minilla and Kumonga, along with other Toho monsters like Gorosaurus, Manda, Baragon and Varan, all ultimately fighting King Ghidorah.
- Godzilla: Final Wars features almost every monster introduced in the Showa era facing off against Godzilla.
- Kamen Rider:
- The first film-length crossover was Birth of the Tenth! Gather All Kamen Riders!!, which featured all nine previous Riders and introduced the tenth, Kamen Rider ZX.
- Kamen Rider Kiva began the trend of each Rider season having a crossover movie with its immediate predecessor, usually to deal with a villain based on both of their shows or an agent of the Nebulous Evil Organization Foundation X. Some of these movies also feature appearances by a smattering of previous Riders whose actors were available at the time, who show up to help when the main pair need the cavalry.
- Kamen Rider × Super Sentai: Super Hero Taisen and its followups are larger crossovers featuring not just every Kamen Rider, but every Super Sentai as well. Usually only the current Rider, the current Sentai, and a few previous characters have appearances out of costume. Everyone else only appears in costume, and is either voiceless or played by soundalikes of questionable accuracy.
- Marvel Cinematic Universe:
- The Avengers (2012) is a crisis crossover for all Marvel Studios movies starting with 2008's Iron Man. However, this was the plan from the very start, as it was first set up in The Stinger of Iron Man and just building with each new film released in the next three years.
- Avengers: Age of Ultron reunites the team in reaction to events laid out in the intervening films, as well as being influenced by events in Agents of S.H.I.E.L.D. (though the Agents of S.H.I.E.L.D. don't appear).
- Captain America: Civil War crosses over the cast of the Captain America movies with the cast of the Avengers movies (sans Thor and The Incredible Hulk), as well as unaffiliated heroes Black Panther, Ant-Man, and Spider-Man.
- Avengers: Infinity War once again ties together various sub-franchises from across the MCU, including ones not included in the previous two Avengers films, in order to both deal with the Greater-Scope Villain of Phases 1-3 (namely Thanos), and to finally tie off the Infinity Stone Myth Arc that has been running through The 'Verse since mid-Phase 1. It has the largest number of superheroes in any MCU film to date.
- Avengers: Endgame is the direct continuation of the events of Infinity War, climaxing in a Big Badass Battle Sequence between the Avengers and their many allies verses Thanos's army.
- Spider-Man: No Way Home is such a big Crisis Crossover that it brings together the characters, and therefore universes, of the Spider-Man films already in the Marvel Cinematic Universe (and also Doctor Strange with Stephen's supporting role and a cameo by Wong), with the two cinematic predecessors and pits the three Spider-Man incarnations against a Legion of Doom consisting of most of their villains. It also crosses over further with a mid-credits cameo of Tom Hardy's Eddie Brock and Venom.
- Space Jam: A New Legacy brings together a vast menagerie of Warner Brothers franchises.
- Ultra Series movies tend to do this:
- Ultraman Saga has Ultraman Zero of the M78 universe working together with Ultraman Dyna and Ultraman Cosmos, despite the latter two being from completely different dimensions: the reason of their unity is because Dyna summoned them through a dimensional portal. They're working together to defeat Hyper-Zetton, an empowered incarnation of the already powerful monster known as Zetton, after all.
- Ultraman Ginga S The Movie: Showdown! The 10 Ultra Warriors! features Ultraman Ginga and Victory being trained by the aforementioed Zero, to unleash a more powerful fusion form and release various imprisoned Ultras - Ultraman Tiga, Ultraman Dyna, Ultraman Gaia, Ultraman Max, Ultraman Nexus, Ultraman Mebius, and his latest addition, Ultraman Cosmos - so they may work together and defeat a powerful Space-Time Demon, Etelgar, who intends to enslave Ultras and seeks Ginga, Victory and Zero as latest additions to his collection.
- In Ultraman X The Movie: Here Comes! Our Ultraman!, Ultraman X ends up working with the original Ultraman and Ultraman Tiga to defeat Zaigorg, the Ultramen universe equivalent to Satan, who had been unleashed into the world. The ending also features five other Ultras, including Ginga, Victory and Zero, battling Zaigorg's monster army across the globe while X takes on Zaigorg with Ultraman and Tiga assisting him.
- Ultraman Taiga The Movie: New Generation Climax has eleven Ultra heroes, from Ginga to Taiga, working in tandem in order to destroy the Malicious Demonic Monster Grimdo.
Literature
- Eugene Sue's 3rd major novel Mysteries Of A People in its final chapter brings the Hero of his First Rodolph into the story as well as the villain of his second (An Evil Jesuit) to do battle with each other.
- A Jane Austen version happens in Death Comes to Pemberley. Wickham's situation ends up briefly binding Pride and Prejudice with Persuasion and Emma.
- Star Trek: Destiny: An epic (and we do mean epic) trilogy of novels of the Star Trek Expanded Universe, bringing together characters from The Next Generation, Titan, Enterprise, Deep Space Nine and Voyager to tell the story of the apocalyptic final war between the Federation and the Borg.
- The Thursday Next series can be seen as a variant of this in later volumes, with literary characters such as Miss Havisham and the Cheshire Cat playing roles in the salvation of all written literature. It runs closer to a Kingdom Hearts-style crossover than a comic-style crossover, though.
- The first phase of the Family Chronicles have this. Heroes And Villains, Death In The DEEPS and Darkness Falls are separate rosters of characters, but the other two books in the phase, Blood And Fire and The Blackest Night combine the three separate casts into one fight for the world.
- The Grand Finale of Warrior Cats, The Last Hope is as close as you can get to a self-contained Crisis Crossover, with loads of screentime for all past and present protagonists, the final battles with all the past villains, and cameos by nearly every ThunderClan cat from the first arc.
- Kim Newman's superhero deconstruction "Coastal City
", about what it would actually be like to live in a typical comicbook universe, mentions that "once a year, there would be a crossover free-for-all, frequently involving something enormously powerful from another galaxy, and all the hypers would destroy the city while saving the universe."
- Michael Moorcock has the "Agak and Gagak" incident, in which no less than four incarnations of the Eternal Champion (Elric, Erekose, Corum and Hawkmoon) are summoned to fight two Eldritch Abominations who threaten the entire Multiverse. It is depicted in two separate novels, from Elric's perspective in The Sailor on the Seas of Fate and Hawkmoon's in The Quest for Tanelorn.
- SD Gundam The Last World features characters from throughout the SD Gundam universe trying to survive an Involuntary Battle to the Death in the titular "Last World". To wit, alongside Sen-Pu Ninja Exia and Gundam the Gold, there's also characters from the Knight Gundam series, BB Senshi Sangokuden, SD Command Chronicles, SD Gundam Force, Gundlander, and SD Gundam Space Time Transfer Gun Voyage just to name a few.
Live-Action TV
- CSIVerse has been known to cross storylines and characters between its various incarnations, as has the Law & Order series. This most commonly takes place during sweeps.
- The most prominent CSI example is their "trilogy" from Nov of 2009, which concerned a nation-wide human trafficking ring Ray Langston was after due to young woman being kidnapped. It starts on CSI: Miami with "Bone Voyage," travels up the East Coast to CSI: NY with "Hammer Down," and wraps up in Vegas with CSI's "The Lost Girls."
- There was in fact a Law & Order massive crossover in the works, involving a terrorist plot to attack NYC and several teams of detectives from different squads all working the case together. The idea got shelved after 9/11.
- During the winter of 1999, in line with its plans to air the Miniseries Storm of the Century, ABC had a raging winter storm strike all four of its soap operas. Fitting, as two were set in upstate Pennsylvania, while the other two (one of which was a Spin-Off of the other) was set in upstate New York.
- American Horror Story: Apocalypse is effectively one of these for the American Horror Story universe, as it combines several characters and story threads from different seasons (but especially Murder House and Coven) to reverse its titular apocalypse.
- The CW's Arrowverse has been doing these ever since The Flash premiered; it's not uncommon for characters to visit each other, but the ones that air each fall just before the winter break are advertised as big event TV. Originally they were just with the parent show, Arrow, they've gotten bigger each year as more and more shows are added to the franchise. They are in order:
- The 2014 event, Flash vs. Arrow, where Flash and Arrow face off and visit each other's cities to understand each other better.
- The 2015 event, Heroes Join Forces was used to promote the third Arrowverse show, Legends of Tomorrow by having Teams Arrow and Flash team-up to help Kendra Saunders and Carter Hall escape the wrath of Vandal Savage, the Big Bad of Legends Season 1.
- The 2016 event, Invasion!, an adaption of the Invasion! arc of the 1980's expanded the crossover by having play across all four shows: Supergirl, The Flash, Arrow, and Legends of Tomorrow by having Barry Allen unite all the heroes he knows to stop an impending invasion from an alien race called the Dominators.
- The 2017 event, Crisis on Earth-X is even bigger. Whereas Invasion! was technically only a three part event (with Supergirl being just a tie-in to the main event), this crossover fully plays out over all four episodes, equally juggling the storylines of each show, as well as serving as a lead-in to Freedom Fighters: The Ray. And it actually has lasting repercussions for the Arrowverse's future, as Barry and Iris get married, as do Oliver and Felicity, while Martin Stein is Killed Off for Real.
- The 2018 event, Elseworlds, dials things back somewhat, "only" being a crossover between The Flash, Arrow, and Supergirl, though in a surprising twist the 1990 Flash ended up making an appearance.note That said, it is notably a Breather Episode compared to the previous year's crossover and is used to promote the then-upcomingBatwoman. Ultimately, it is just a setup for the following year's event.
- The 2019-2020 event is Crisis on Infinite Earths, having been foreshadowed steadily since The Flash Season 1 and sporadically throughout the other shows, it featured five episodes that span all recurrent Arrowverse series, including Supergirl, Batwoman, The Flash, Arrow, and Legends of Tomorrow (the last of these actually began its forthcoming season after the Crisis). This was the last time Arrow got to participate, as the show ended in 2020 and its final season focuses on Tonight The Hero Dies in the lead-up to and the aftermath of the Crisis. It is an adaptation of the classic comic of the same name AKA the Trope Namer. In addition to the return of 1990 Flash, it also features a cavalcade of guest and cameo appearances from other DC live-action adaptations from outside of the Arrowverse continuity, including Tim Burton's Batman, Titans, the 1960s Batman series, Smallville, a merger of Superman: The Movie and Superman Returnsnote , Birds of Prey, Lucifer, Black Lightning, Swamp Thing, Doom Patrol and the DC Extended Universe. It also marks the debut of the titular character of Stargirl, ahead of the series' premiere on the DC Universe streaming service (which includes the aforementioned Titans, Doom Patrol and Swamp Thing)note . As with the comic book, this crossover has a huge impact on the franchise, as it ends up merging the Black Lightning Earth with Earth-38 (the universe where Supergirl is set) and Earth-1 (where the other four shows are set) into a single new reality.
- The Defenders (2017) is the self-contained type. It is an eight episode miniseries that sees Matt Murdock, Jessica Jones, Luke Cage, and Danny Rand team up to fight the Hand, a villainous organization built up in Daredevil season 2 and Iron Fist season 1. The crossover has lasting repercussions for the next phase of the Netflix shows, as Matt's "death" in the climax, and subsequent turning up at a convent, sets up the third season of Daredevil to do a loose adaptation of the renowned Born Again storyline.
- Doctor Who:
- Pre-revival, the show would occasionally have multi-Doctor special episodes. They had "The Three Doctors" (First/Second/Third), "The Five Doctors" (First/Second/Third/Fourth/Fifth), and "The Two Doctors" (Second/Sixth).
- The two-part Series 4 finale, "The Stolen Earth"/"Journey's End", crosses over with spinoffs Torchwood and The Sarah Jane Adventures, and also brings in almost all of the Doctor's companions (a majority of the companions of the Russell T Davies era as a whole) to appear in the revived series to date. (Although it should be noted that this did not have any on-screen content or long-term consequences in either of the spin-off shows.)
- "The Day of the Doctor" sees the Tenth, Eleventh, and retroactively introduced War Doctors work together to end the Time War. Eventually, all 13 Doctors (including the 12th, yet to debut Doctor) come together to end the Time War and prevent the destruction of the Time Lords.
- "Twice Upon a Time" has the Twelfth Doctor team up with his original incarnation, the First Doctor himself.
- A rather famous "Hurricane Saturday" event that happened on The Golden Girls and its spinoffs Empty Nest and Nurses (Nurses was technically a spinoff of Empty Nest, but go with it.) A hurricane hit during The Golden Girls and Empty Nest and the hospital of Nurses dealt with the aftermath. A similar even happened with a full moon, but that better fit as a Cross Through.
- Ten years of Kamen Rider's Heisei era (and much later on, the franchise's 38 years up to that point) were celebrated in Kamen Rider Decade, where Decade (obviously the tenth) must travel across the Kamen Rider multiverse to save it from total destruction.
- The two-part Grand Finale of Kamen Rider Wizard features all fourteen Heisei era Riders up until that point (as well as an Early-Bird Cameo appearance from Kamen Rider Gaim) teaming up to prevent a new villain from unleashing all of the franchise's past Monsters of the Week upon the Earth.
- The Grand Finale of the Heisei era is Kamen Rider Zi-O, guest starring returning characters from previous series. Zi-O must avoid his fate of becoming an Evil Overlord in the future while preventing the antagonists from successfully grooming a substitute with the Another Riders they create, and the key to both parties' goals lie in the legendary Riders of the past.
- The three crossover episodes that NCIS: New Orleans has shared with its parent show—one of which was its Back Door Pilot—had a case beginning in Washington on NCIS before evidence took them to New Orleans.
- Power Rangers has done something like this a few times (not counting traditional two-season teamups), in what was originally meant to be the Grand Finale and as part of Milestone Celebrations.
- The first, Countdown to Destruction during the sixth season, featured Dark Specter and the United Alliance of Evil declaring war on the entire universe. While the Space Rangers are the main protagonists, making this a Downplayed Trope, the Aquitar Rangers and Zeo Gold are shown fighting elsewhere.
- Ten Red Rangers would later unite for a special mission in the tenth season, to stop the Machine Empire's remaining generals from re-activating Zedd's war Zord Serpentera as part of the 10th anniversary celebration.
- The twenty-first season took the previous Rangers examples up to eleven with its Grand Finale The Legendary Battle, where every Ranger team to ever lead a season (including two from other planets, one from the future and one from an Alternate Continuity for some reason) come together to fight an Armada dwarfing the United Alliance of Evil declaring war on Earth. Most of the war is actually off-screen, with the Legendary Rangers fighting and rescuing people elsewhere while the season's own Mega Rangers fight the Emperor and high command; they all come together in time for the final battle against the last remnants of the army. This served as the 20th anniversary celebration, though the post-Channel Hop scheduling of the show delayed it to the 21st year.
- The finale of Power Rangers Cosmic Fury features multiple teams attempting to stop a Reverse Z-Wave from destroying all good in the universe; serving as the Grand Finale to 30 years of the franchise ahead of an upcoming reboot.
- Space Squad: Space Sheriff Gavan Vs. Tokusou Sentai Dekaranger involves Geki/the new Gavan and the Dekarangers teaming up to fight an alliance between Metal Heroes villains, with Madgallant as the movie's main villain. On top of this, the establishment of a space squad was done in response to another universe being dominated by evil, to prevent such an event from happening again.
- Super Sentai. In the seasonal crossovers, the series from Bakuryuu Sentai Abaranger to Engine Sentai Go-onger are nominally connected by mentions of the Dino House where one character from series A met a character from series B.
- Kamen Rider X Super Sentai Superhero Taisen is starting to look like this as well, with Decade's Dai-Shocker being ressurected, with their opposite number being the similarly-structured Dai-Zangyack Fleet led by GokaiRed of the Gokaigers. Both the Super Sentai 199 and the All Riders are at the very middle, wondering just what is going on.
- The Super Hero Taisen series has become an annual tradition, though the focus has been shifting more and more toward the Rider side of things.
Magazines
- This trope is spoofed in MAD's article about The 8 Greatest Comic Books of All Time, with one of them being the fake issue Multiple Issues: Infinite Identity Countdown to Final Crisis Ad Infinitum: The Introducing. This issue follows on from Exigency Climax: Final Crisis Across Multi-Realities: The Finality, with every DC Hero from every universe introducing themselves to each other... before the next crossover event happens.
Multi-Media
- The Doctor Who Expanded Universe has had multi-media crossover events involving multiple different spin-off works.
- Time Lord Victorious (2019-22 — intended to be 2019-20, but some works were delayed by the COVID-19 pandemic), which centered on the Eighth, Ninth and Tenth Doctors, and included New Series Adventures novels, Big Finish Doctor Who dramas, comic arcs in both Doctor Who (Titan) and the Doctor Who Magazine comic strip, webcasts, a T-shirt
, and two live theatrical events, A Dalek Awakens and Time Fracture.
- Doom's Day (2023), which was set in a single 24-hour day from the perspective of the assassin Doom, in search of the Doctor, and included a webcast, text stories on the BBC website, arcs in both the Titan Doctor Who comic and the Doctor Who Magazine strip, content in the Doctor Who: Lost in Time mobile game, a prose novel, and audio dramas from both Big Finish and BBC Audio.

Mythology and Religion
- Older Than Feudalism: Greek Mythology knows at least two major crossover events: the Argonautica (the story of Jason, the Argonauts, and the Golden Fleece) and the Calydonian Boar Hunt a few years later. Large arc-based events like the Theban Wars and the Trojan War may also count.
- The earliest stratum of Arthurian Legend drew folk heroes and gods from lots of disparate Celtic myths and legends to form King Arthur's court.
- The Æsir-Vanir War, where the two pantheons of Norse gods the Æsir and Vanir (whom some suggest originated from two different religions that was merged) fight and ultimately becomes one tribe, and Ragnarök, where characters from all over Norse mythology meet up to kill each-other.
Podcasts
- Are You Afraid Of The Dark Universe aims to revive the Dark Universe by mimicking the style of the Marvel Cinemtic Universe, so naturally each Phase of film pitches ends in one of these. Phase One had Dark Legion: House of Dracula, followed by Dark Legion: The Mummy's Hand, Dark Legion: Death's Door, and Dark Legion: Hell on Earth. This also applies to some of the other film pitches. Van Helsing sees a major team-up between their various characters and is described as their version of Captain America: Civil War. Their version of Mystery Men also takes this form, as while it's tonally akin to the original the cast is actually made up of secondary characters and characters introduced in various guest pitch episodes.
Professional Wrestling
- The Invasion storyline in the WWE was meant to be this, with top WCW talent (the then WWF had bought out WCW) "invading" WWF. However contract issues meant that many of the WCW's top stars weren't involved.
- Rather than being involved in every aspect of a single company, The Hostile Youth Project was out to invade every North Carolina promotion in 2002.
Tabletop Games
- The Abyssal Plague, a series of Dungeons & Dragons Tie In Novels which started out in the Nentir Vale setting but grew to involve other D&D worlds too, including the Forgotten Realms, Eberron and Dark Sun.
- The D&D settings Planescape and Spelljammer are made of this trope, explicitly designed to allow travel and storylines across D&D's other universes. While it was implied for years that all D&D games belonged to the same multiverse, these were two official company lines that supported it.
- The book Die, Vecna, Die had the titular lich escape the Mists, leading the party to fight in Greyhawk, across various planes, and culminating in an attack on Sigil. Canonically, this module is the story reason for the changes from 2nd Ed. to 3rd.
- The 50th Anniversary adventure, Vecna: Eve of Ruin crosses over Forgotten Realms, Planescape, Spelljammer, Eberron, Ravenloft, Dragonlance, and Greyhawk as heroes and characters fight to stop Vecna, who's now an aspiring Multiversal Conqueror.
- The Old World of Darkness had a few thematic ones toward the end of its line, but an official one with the Time of Judgment series of books, officially ending the old settings.
- Rifts is this to the Palladium systems of games. The setting is of Earth a couple hundred years in the future, after having been transformed into a multidimensional hub, with beings from all over time and space arriving, either by choice or forcibly.
- More specifically, Palladium ran a series of Sourcebooks called "Minion Wars," detailing a conflict between two different versions of Hell that spilled out across the Megaverse. Sourcebooks were written for several Palladium titles, describing how those specific settings were affected by the war.
- Reality Storm: When Worlds Collide, a crossover between Silver Age Sentinels and Champions.
- The OblivAeon event in Sentinels of the Multiverse, which not only sees villains turn hero (permanently or otherwise), but includes heroes from alternate universes rushing to help fight in the grand finale.
- In Wargames, characters and factions beating the crap of each other is their entire point, but sometimes events in the story get too out of hand and several facions are drawn into the ensuing conflict. These wars are commonly told in special supplements commonly named "Campaign Books". These books usually include the background of the conflict, special rules and scenarios to replicate in the tabletop the battles of the mentioned conflict and the rules of units, soldiers and characters who got involved in said conflict, regardless of faction or allegiance. Sometimes, these camapigns and their resolution gets it's way into the story itself and becomes a part of it, specially in the ficitional wargames.
- Years ago, Games Workshop hosted events called "World Campaigns" which involved every faction of their main games Warhammer or Warhammer 40,000 and threw them into a war where everyone had someting at stake, with different levels of focus (Usually both Empires being the highest) in the story. These campaigns were to be played by players all around the world and games deciding (usually) the outcome of said wars. Some Campaigns were reinforced by Campagin books like normal campaigns. The most famous are included in their games entries.
- 40K had campaign suppements way back to 2nd Edition, like Storm of Vengeance, but other, more recent ones are Armageddon and Eye of Terror related to the World campaign of the same name. The most recent ones are The Red Waagh and Shield of Baal series of books and boxed sets wich the firt Series pits the Astra Militarum, and Space Wolves aganist the Orks, and the second the Astra Militarum, Sisters of Battle, Blood Angels and Necrons aganist the Tyranids.
- Warhammer also had its share of campaigns, usually in the form of "campaign boxes", normally centered in two or three of the factions that included the campaign books and special markers or scenery, all capboard. Some of most famous of these Campaign boxes are Idol of Mork and Tears of Isha. 6th Edition onwards, the campaign box format was dropped in favor of the traditional book, being the most famous campaigns The Shadow over Albion, Storm of Chaos and The Nemesis Crown also World Campaigns (albeit The Nemesis Crown was retconned the istant the campaign ended and Storm of Chaos suffered the same fate in the beggining of 8th Ed., The Shadow over Albion sticked). The most famous (and controversial) of the recent campaigns is the Warhammer: The End Times series of books. The End times tells the story of the final days of the world and the efforts of EVERYONE to stop it or bring it. No one knows for sure if it will stick, but everyone fears that it will. No need to say that it didn't end well.

Video Games
- Astro Boy: Omega Factor is a retelling of some sagas from the original Astro Boy manga and its anime adaptations, but featuring characters and events from other Osamu Tezuka series. Sharaku from The Three-Eyed One is the Big Bad who conspires against the heroes. The game received a follow-up in the form of Black Jack: Hi no Tori Hen, which does the same for Jack's story. Astro is portrayed as the A.I. for the U-18 super computer before Dr. Tenma built his body, and the story involves an evil scheme by Alabaster and the pursuit for the Phoenix.
- The King of Fighters series of fighting games is a Crisis Crossover for SNK, featuring characters from Art of Fighting, Fatal Fury, Ikari Warriors and Psycho Soldier, as well as creating several characters exclusive to the series (Iori Yagami, Kyo Kusanagi, and Rugal Bernstein being the most notable).
- Super Smash Bros.:
- Super Smash Bros. Brawl has the story of Subspace Emissary. It involves all of Nintendo's major heroes (and a couple of others) teaming up to stop the titular Subspace Emissary from destroying the Smash Bros. universe. However, unlike the typical Crisis Crossover, this explicitly takes place in an Alternate Continuity where the characters are all trophies that come to life and fight.
- Super Smash Bros. Ultimate brings together every single Smash Bros. fighter ever, plus a few new ones (with even more joining the fray later on), to take down the "ultimate enemy" named Galeem and his just-as-evil counterpart Dharkon in World of Light.
- EXTRAPOWER: Attack of Darkforce is technically this for the EXTRAPOWER series, despite being the first game released. Characters created over the course of Lucky Lamp Project's members lives unite together to face the threat of Dark Force's universal conquest. Later games would release these teams to their own stories and settings.
- Dissidia Final Fantasy has the evil god Chaos revive villains from Final Fantasy through Final Fantasy X in an attempt to sieze the Crystals and change history. Chaos' opposite number, the goddess Cosmos, calls on the heroes from the same games to unite and save the universe.
- Gundam Vs. Gundam NEXT has the Devil Gundam come to life and take over arcade games representing the entire Gundam franchise from the original series through Gundam 00, forcing the characters to team up to deal with the threat.
- .hack//Link is going this way, as characters from both of the "revisions" of The World are in it. (Tokkio's first two party members are Tsukasa from SIGN and Haseo from G.U., for example.)
- The Nicktoons Unite! series serve as this for Nickelodeon, with SpongeBob SquarePants, Danny Phantom, Jimmy Neutron, and one or two other universes deal with a multiuniversal threat, differing each game.
- Nickelodeon All-Star Brawl 2 features a single-player mode where the main fighter cast and other characters and elements from their shows fight enemies in a roguelike campaign to stop Danny Phantom villain Vlad Plasmius from taking over the minds and worlds of the Nicktoons multiverse.
- Cartoon Network has the MMORPG FusionFall, though its art style makes it clear it is an Alternate Universe.
- Similiary to the Kamen Rider Decade example above, ASCII Media Works celebrated the 15th anniversary of their Dengeki Bunko imprint of Light Novels with the Nintendo DS RPG Dengeki Gakuen RPG: Cross of Venus, where an evil organization is attempting to derail the storylines of eight of their series and so your not-so-nameless protagonist and Shana must form a rag-tag group with their worlds' heroines to save their printed existences.
- Inverted in Poker Night at the Inventory, where Strong Bad, Max, The Heavy, and Tycho (from Homestar Runner, Sam & Max: Freelance Police, Team Fortress 2, and Penny Arcade respectively) team up to play poker. The sequel has Brock Samson, CL4P-TR4P, Ash Williams, Sam, and GLaDOS (from The Venture Bros., Borderlands, Evil Dead, Sam & Max: Freelance Police, and Portal, respectively.)
- The Marvel vs. Capcom series is this for both Marvel and Capcom.
- The original Marvel vs. Capcom: Clash of Super Heroes reused the plot of the Onslaught saga and adding in Capcom characters.
- Marvel vs. Capcom 2 has a more straightforward plot where Ruby Heart was gathering characters from both companies to deal with Abyss.
- Marvel vs. Capcom 3 has Wesker and Doctor Doom team up, crossing over the Marvel and Capcom universes, and awakening Galactus in the process.
- Marvel vs. Capcom: Infinite has Death and Jedah Dohma intend to fuse the two worlds together, resulting in a fusion of Ultron and Sigma with two of the Infinity Stones who seeks to dominate all life.
- The Suikoden series is headed this direction nowadays, but with original characters in an attempted re-invention. Suikoden Tierkreis introduced the multiverse concept and the next game is said to be focused around this.
- Resident Evil 6 is this for the Resident Evil franchise. Including Leon Kennedy, Chris Redfield, Ada Wong, and even the returned Sherry Birkin and a son of Albert Wesker, all face off against a new, global bioterrorism threat, rather than confined to certain locations to chase down a singular threat.
- EndWar is one of these for the Tom Clancy game verse, including former members of the Ghost Recon and Rainbow, along with the H.A.W.X. squadron and Third Echelon.
- Magical Girl Lyrical Nanoha A's Portable: The Gears of Destiny, which featured an unstable Humanoid Abomination whose out of control powers dragged in characters across time and space and produced Virtual Ghosts of dead people, incidentally allowing characters from the various recent installations of the franchise at the time (The Movie First, Vivid, and Force) to join in the fray against the new threat.
- As part of Artix Entertainment's 10th anniversary celebration, six of their active online games at the time (AdventureQuest, DragonFable, MechQuest, AdventureQuest Worlds, EpicDuel, and HeroSmash) were attacked by Chairman Platinum and his company, EbilCorp, sparking a cooperative war in which the playerbases of all six games had to band together as one and eliminate the invading forces in every single game within a week. The players won.
- Prior to this, there was a St. Patrick's Day event (known in game as the Blarney War or Lucky War in-universe) that united the AdventureQuest, DragonFable, and MechQuest timelines in a successive war, and a war against Shearhide that was a crossover between AdventureQuest and WarpForce.
- Bringing the tradition into video games, Mortal Kombat vs. DC Universe has a plot along these lines with Darkseid being somehow and involuntarily merged (for the third time), now with Shao Kahn into an Humanoid Abomination who grinds the two universes into destruction just by existing. Midway considers it an Elseworld for the DC side of the story, though they did write the Kombat side so as to implicitly fit in between Mortal Kombat 3 and Mortal Kombat 4 (as well as hand it a Continuity Nod in Mortal Kombat 9: the Training Mode description for Shang Tsung's M-rated Captain Ersatz version of The Joker's gun fatality is "Shang Tsung has picked up a few tricks from previous opponents."). In real life, the crossover had the effect of Warner Bros., DC's parent company, being allowed to acquire Midway's Mortal Kombat division (now named Netherrealm Studios) when Midway went bankrupt.
- Though Jump Super Stars and its sequel have an Excuse Plot, it still does amount to Dr. Mashirito from Doctor Slump stirring up trouble, while the J-Heroes/Heroines try to stop him.
- What could possibly be powerful enough that all of the numbered Shin Megami Tensei protagonists, each of which powerful enough to fight against YHVH Himself, would have to team up with Nanashi, who actually does kill Him? Of course none other than Stephen, establishing his position as All-Powerful Bystander once and for all with a boss fight that is essentially YHVH on steroids.
- The crossover event Accel World vs Sword Art Online: Millennium Twilight, involves the Accel World and Sword Art Online characters being brought together and being forced to team-up against the threat that transcends time, Persona Vabel.
- Fate/Grand Order features nearly every Servant, and many non-Servant characters (some now summonable as Servants), from Fate/stay night, Fate/Zero, Fate/EXTRA, Fate/Apocrypha, and even Fate/Prototype and Fate/kaleid liner PRISMA☆ILLYA, in a storyline where the Chaldea Security Organization must fix time anomalies that could destroy the world. There are even characters from non-Fate works such as The Garden of Sinners.
- The Detectives United series is this for three of the Elephant Games mystery game series (Haunted Hotel, Mystery Trackers, and Grim Tales), with the three player characters coming together to combat supernatural forces that even their individual Occult Detective skills would not be able to overcome.
- Magia Record brings in all notable magical girls from the entire Puella Magi Madoka Magica franchise, including Kazumi Magica, Oriko Magica, Tart Magica, and Suzune Magica. In addition to a rather large cast of new characters. Most spinoff characters only appear in side-stories (within the game) and are not directly involved in the main storyline, but they all interact with Magia Record's main cast in some way.
- Worlds Align is this for AMAX Interactive. It posits that their games each take place in separate dimensions, which are connected, and the heroes of each series are "Watchers" who protect their worlds. When a great evil threatens the worlds of Dark Tales, Puppetshow, and Haunted Halls, they reach out to another Watcher - the player, who has been appointed to this role for the "real world." You actually play the games as yourself, assisting characters in ending the crisis, with No Fourth Wall keeping the characters from acknowledging that you're a real person who knows them from games.
- The Super Robot Wars series is built around bringing together Humongous Mecha from many different anime series to team up and fight.
Webcomics
- In late 2008, Irregular Webcomic! had most of its separate "themes" converge when simultaneous paradoxes occur and the universe imploded. Eventually the characters managed to restart the universe, but most themes suffered a Continuity Reboot in the process.
- Every theme set in the real world once again converged for the Grand Finale in 2010-2011, all being transported to the 1940s to defeat Hitler and fix what remained of the temporal paradoxes from the previous crossover arc.
- Least I Could Do parodied this with the storyline "Ultimate Final Civil War Invasion Crisis Thing", where the gaming webcomics (including Penny Arcade and Ctrl+Alt+Del) are attempting to take out the "straight comedy" comics and reassert their dominance. Receives several lampshades, such as when Faye calls the plot weak, and Rayne counters, "So was a cosmic vampire, but that didn't stop DC."
- When Emily and Tesrin of All Over the House crash-landed
in The Life of Nob T. Mouse, it kick-started a crossover that changed both comics permanently.
- The Crossoverlord is one between several superhero webcomics, including Lightbringer, Mechagical Girl Lisa ANT , Mindmistress, Dasien and Dead Debbie from Indefensible Positions. The sequel, Crossoverkill, retains Mindmistress and adds Energize, Yuuki from Sparkling Generation Valkyrie Yuuki, Fusion, Captain Perfect from Bad Guy High, Majestic Knight and Magellan Hoodoo.
Web Original
- Critical Role: The third campaign revolves entirely around Ludinus Da'leth's plan to unleash an Eldritch Abomination that will devour the gods, and the forces of Exandria gathering together to fight them. Bell's Hells encounter multiple player characters from previous campaigns (they meet Keyleth, Percy, Vex, and Pike from Vox Machina while trying to resurrect Laudna, and Caleb and Beau from the Mighty Nein during their attack on the Malleus Key), and temporarily gain Essek Thelyss, a beloved NPC from Campaign 2, as a traveling companion. The end of the campaign makes the crossover complete, as the players reprise their roles as Vox Machina, the Mighty Nein, and Bell's Hells for a three-pronged assault on the enemy base — the Hells and the Nein even travel to their respective destinations together, forcing each player to play two characters at the same time.
- These have become the main storyline in I'm a Marvel... And I'm a DC, as is to be expected in a meta series for both Marvel and DC. Having Deadpool around means that inter-series continuity is now lampshaded.
- The blogosphere side of The Slender Man Mythos has had a few. Some examples include the Winter Solstice story in Observe and Terminate and A Hint of Serendipity, and the Wedding crossover from Take The Myth.
- The Fear Mythos, a spin-off of The Slender Man Mythos, had one early in its existence: The Birth of the Manufactured Newborn. It involved four different blogs intertwining their stories: The Hunter, The Devil and God Are, They Sought It With Thimbles, and Hidden in the Trees. The crossover involved a conspiracy by the Fears to birth a new one into their ranks, while the human characters either try to stop them or try to help them.
Western Animation
- Dexter's Laboratory: Last But Not Beast had the Dexter, Monkey and Justice Friends segments connected via the giant monster destroying Japan. The Monkey segment even skips its usual opening credits to continue the story.
- Turtles Forever: It deals with the 2000 Shredder returning from his exile, taking over the 1980s Shredder's Technodrome, and, after learning of the TMNT Multiverse, he plans to go conquer it, until he learns that there are teams of TMNT in each and every reality. He goes after the original Mirage Turtles in order to destroy all the Turtles, and three sets of Turtle Teams set off to stop him.
- Hanna-Barbera did this with the "Council of Doom" storyline in Space Ghost with Space Ghost eventually meeting Moby Dick, Mighty Mightor, Shazzan, and The Herculoids. Sometimes, the Cartoon Network (and later, Boomerang) would show the whole thing.
- The later Space Stars series did this at the end of each show with a "Space Stars Finale" which features a team up of characters from two or more of the show's segments (Teen Force, Space Ghost, The Herculoids, and Astro and the Space Mutts).
- Another Hanna-Barbera example would be Yogi's Ark Lark which by definition featured characters joining together to deal with a crisis. Except the crisis in question wasn't a comic book level event as much as the planet has too much pollution kind.
- The Phoenix Saga of X-Men: The Animated Series was a borderline example. Although there were no actual team ups, it used appearances of other Marvel Comics characters to emphasise the seriousness of the whole thing. Captain Britain and Doctor Strange were seen reacting to the Phoenix and Spider-Man (albeit only his silhouette and his hand) and War Machine were seen protecting civilians in New York. In the sequel, the Dark Phoenix Saga, Doctor Strange briefly appeared again, along with Thor, a Watcher and Eternity.
- A made-for-TV animated movie called The Man Who Hated Laughter brought together a big group of newspaper comic strip characters — Blondie, Popeye, Beetle Bailey, Hi and Lois, Snuffy Smith — who are ultimately saved from a comics-hating villain by the combined forces of a group of newspaper adventure strip heroes (Mandrake the Magician, Flash Gordon, Prince Valiant, The Phantom, and Steve Canyon). All the characters are owned by King Features Syndicate.
- Hurricane Flozell blew her way into all three Seth MacFarlane shows, The Cleveland Show, Family Guy and American Dad! culminating in the final scene of the American Dad episode where Cleveland, Stan, and Peter have a standoff with guns.
- The feature-length special Rudolph and Frosty's Christmas in July by Rankin Bass, which brought back several characters from all of their holiday specials and many of the voice actors from the previous specials as well. It involves Rudolph, Frosty, and Santa trying to stop an evil wizard named Winterbolt. It also contains a bounty of Continuity Porn, with callbacks to other previous specials such as Santa Claus is Comin' to Town, Rudolph's Shiny New Year, and Frosty's Winter Wonderland (with the notable exception of The Year Without a Santa Claus, leaving the poor Miser Brothers snubbed).
- Spider-Man: The Animated Series: While the show had many crossovers, the series had two of this nature near the end of it's run. "Secret Wars" which saw Spider-Man drafted to be a leader in a literal battle of good vs evil where he picks the Fantastic Four, Storm, Captain America, Black Cat and Iron Man to help take on the likes of Dr. Doom, Dr. Octopus, The Lizard, Alister Symthe and Red Skull. The final arc of the series, "Spider Wars", saw him teaming with various Spider-Men from different alternate universes (one with six arms, one with Doc Ock's metal tentacles, one who was a billionaire and built his own tech, one who didn't have any powers, and one who was the Scarlet Spider) to stop Spider-Carnage, a murderous version of Spider-Man who fused with the Carnage symbiote.
- Teen Titans Go! vs. Teen Titans features the 2013 Teen Titans meeting up with their 2003 counterparts to do battle against both Go!Trigon and a freshly resurrected 2003 Trigon. Multiple incarnations of Teen Titans throughout the multiverse are eventually summoned to do battle with this new threat alongside the two main teams.
- The premise of Pibby, as shown in the trailer, is that an Eldritch Abomination is destroying several different cartoon shows (fictional and real, the latter all owned by Warner Bros.) and killing their casts. Pibby is forced to dimension-hop into these shows and meet with other characters in the hopes of stopping it.
