7[[caption-width-right:350:In this instance, [[WesternAnimation/TeenageMutantNinjaTurtles1987 1987]] meets [[WesternAnimation/TeenageMutantNinjaTurtles2003 2003]], with a pinch of [[ComicBook/TeenageMutantNinjaTurtlesMirage 1984]].]]

9Sometimes when a series is rebooted or adapted to another medium, the different iterations of the franchise will crossover with each other. This is much more likely to happen in series that are fantasy or sci-fi bent or if the successor doesn't have the same cast.
10
11In particular, when a [[LongRunners Long-Runner]] does a {{crossover}} with itself, there will usually be so many iterations that it has to narrow down which ones to focus on. Sometimes they focus on the original version which started the franchise, sometimes they focus on the most popular. It could also be some sort of education about the more unknown versions for casual viewers, and can be the most recent version since that's what is producing more money now. Regardless of which, such crossovers usually give equal focus to two or more versions if both are loved and well-known.
12
13The explanation for how such crossovers can happen may vary: the most common is that all the different versions of the same characters exist as part of a [[TheMultiverse Multiverse]], and once the characters can jump from one universe to another with the [[AppliedPhlebotinum required Phlebotinum]], they can meet themselves. Another (similar but more rare) explanation is that all these versions exist in the same universe, but are separated by a time period and so once they have TimeTravel, the SuperTeam from the recent cartoon can meet themselves from the original 1960 cartoon. This can get weird when the old characters aren't meeting their descendants or substitutes, the characters are the same -- but thanks to a redesign or a ToneShift, they will look similar but still different enough to stand apart, and you're expected to believe that the character changed his looks and his personality over time, so, usually, the "new one" doesn't remember being the "old one".
14
15MeetYourEarlyInstallmentWeirdness is common when the two iterations have major differences between each other. See also CrisisCrossover, BatFamilyCrossover, TheVerse, TheMultiverse. Compare SpinoffSendoff, where a new iteration of a franchise is launched with a supporting appearance by someone from the immediately previous version. SisterTrope of AllianceOfAlternates, where the crossover happens in the same iteration of the franchise (but overlap between the two tropes is not unheard of). DreamMatchGame is a very specific variation found in {{Fighting Game}}s where (nearly) every playable character in the series up to that point [[TheBusCameBack will be brought back for a single installment]], [[CanonDiscontinuity usually ignoring continuity in the process]]. Should not be confused with IntercontinuityCrossover, in which two ''different'' franchises clash together.

17!!Examples:
18[[foldercontrol]]
19[[folder:Anime & Manga]]
20* ''Franchise/{{Digimon}}'':
21** Three of ''Manga/DigimonVTamer01'''s bonus chapters involve Taichi and Zero encountering characters from later Digimon works. Namely, Daisuke (''Anime/DigimonAdventure02''), V-Mon (ditto), Ryo Akiyama (''Videogame/DigimonWonderswanSeries''), Monodramon (ditto) and Takuya (''Anime/DigimonFrontier'').
22** In the last two episodes of ''Anime/DigimonXrosWarsTheYoungHuntersWhoLeaptThroughTime'', the protagonists of the prior seasons of ''Digimon'' shows (Taichi and Agumon from ''Anime/DigimonAdventure'', Daisuke and V-Mon from ''Anime/DigimonAdventure02'', Takato and Guilmon from ''Anime/DigimonTamers'', Takuya from ''Anime/DigimonFrontier'', and Masaru and Agumon from ''Anime/DigimonDataSquad''/''Savers'') arrived to help the heroes against Quartzmon. In addition, Mimi, Palmon, Jou, Gomamon (all from ''Adventure''), and Ruki and Renamon (''Tamers'') also appear in that set of episodes.
23* ''Anime/SuperDragonBallHeroes'' is this for ''Franchise/DragonBall'' to an extent. Specifically, the Prison Planet saga sees Son Goku from ''Anime/DragonBallSuper'' meets Son Goku from ''Anime/DragonBallGT''. Also, some characters from other media like [[VideoGame/DragonBallZArcade Ozotto]] and [[Anime/DragonBallZLordSlug Slug]] appear as enemies in the series.
24* The seven seasons of ''Toys/{{Jewelpet}}'' take place in {{alternate continuit|y}}ies, with the main settings and human characters changing each season along with the Jewelpets' personalities. In Episode 21b of ''Anime/JewelpetMagicalChange'', Ruby gets a call from her ''Anime/Jewelpet2009'' self and learns about her human partner Rinko and her search for the Jewelsticks, followed by the Rubys from the remaining five seasons giving the ''Magical Change'' Ruby a call as well. This culminates in ''the Magical Change Ruby somehow calling herself on her Jewel Pod'', which the Ruby receiving the call doesn't seem to be confused by.
25* ''Franchise/LyricalNanoha'':
26** A one-shot made to celebrate the release of ''[[Anime/MagicalGirlLyricalNanohaAs Magical Girl Lyrical Nanoha: The Movie 2nd A's]]'' featured characters from four separate points in the main continuity's timeline talking with each other about the movie, a direct mention of ''[[VideoGame/MagicalGirlLyricalNanohaAsPortable Gears of Destiny]]'', and a joke involving ''Manga/MagicalGirlLyricalNanohaInnocent''.
27** Due to time-travel shenanigans, ''VideoGame/MagicalGirlLyricalNanohaAsPortable: The Gears of Destiny'' features an encounter between the protagonists of the Portable continuity (an AlternateTimeline where [[spoiler:Reinforce Eins]] survived the Book of Darkness Incident) and several characters only existing in the Primary continuity (where [[spoiler:Eins]] died), effectively creating a crossover between different, mutually exclusive timelines of the series.
28** A drama CD for the game has it cross over with the second movie. Note that the movies are [[RecursiveCanon propaganda produced by the TSAB]] and shouldn't even exist as a separate continuity.
29* ''Anime/PrettyCure'' has ''Anime/PrettyCureAllStars'', a series of crossover movies that teams up all of the ''Pretty Cure'' teams. Each film features Cures from all continuities joining forces to combat a new powerful foe, with focus given to the teams from the currently-airing season and the recently-ended one.
30[[/folder]]
31
32[[folder:Comic Books]]
33* The comic book ''Battlestar Galactica vs. Battlestar Galactica'' is a crossover between the [[Series/BattlestarGalactica1978 two]] [[Series/BattlestarGalactica2003 versions]] of the show.
34* Franchise/TheDCU:
35** Of all {{Crisis Crossover}}s DC Comics has had in its history, among the most fitted to this trope is ''ComicBook/FinalCrisis'', especially when ComicBook/{{Superman}} goes into the [[ComicBook/TheMultiversity Multiverse]] in the ''Superman Beyond'' tie-in and meets a lot of his [[AlternateSelf Alternate Selves]] from parallel universes, with a lot of known Supermen like the [[ComicBook/SupermanRedSon Red Son]], as well as new versions of him, like Overman (an ex-Nazi Superman) and President Calvin Ellis (basically UsefulNotes/BarackObama as the Son of Krypton). All of them work together to stop Darkseid and end the Crisis. It has a spiritual sequel in the ''ComicBook/SupermanRebirth'' storyline "Multiplicity", with Supermen from across the multiverse being kidnapped by a new enemy.
36** Another fitting version of this is ''ComicBook/{{Convergence}}'', in which versions of DC characters from virtually every AlternateUniverse they published up to that point are forced to fight.
37** An earlier form of this happened in ''ComicBook/CrisisOnInfiniteEarths'', where Superman met his Earth-2 and later Earth-Prime counterparts, which became a major part of the plot of its sequel ''ComicBook/InfiniteCrisis''.
38** And going even further backward, it all started with "[[ComicBook/TheFlash Flash of Two Worlds]]", in which Earth-1 Flash (Barry Allen) first encountered Earth-2 Flash (Jay Garrick) after Barry accidentally crossed the "vibration barrier" between [[AlternateUniverse dimensions]]. This was just the start of the CrisisCrossover events DC would have across all of its history.
39** Issue 13 of the ''WebAnimation/DCSuperHeroGirls: Spaced Out'' digital series features Zatanna showing the Super Hero High students [[SpinoffSendoff a peek]] into the universe of [[WesternAnimation/DCSuperHeroGirls the television series]] that premiered in 2019.
40** A case is seen in the events surrounding ''ComicBook/TheFinalDaysOfSuperman''; the [[ComicBook/New52 pre-New 52]] Superman and Lois Lane have ended up in the New 52 timeline, staying off the radar as they raise their son Jonathan. After the N52 Superman falls in battle against a powerful enemy, the pre-N52 Superman decides to take over for him. At least until much later in ''ComicBook/SupermanReborn'', when [[spoiler:the two Supermen and Loises merge with each other.]]
41** There's also ''ComicBook/TheButton'' and ''ComicBook/DoomsdayClock'' which featured [[SlidingScaleOfIdealismVsCynicism the ultimate confrontation between idealism and cynicism]]; Franchise/{{Superman}} vs. [[ComicBook/{{Watchmen}} Dr. Manhattan]].
42* ''ComicBook/GhostbustersIDWComics'': After a crossover with the ''Franchise/TeenageMutantNinjaTurtles'' taught them how to travel the multiverse, the original Film/{{Ghostbusters|1984}} from the 1984 movie encountered those from ''WesternAnimation/TheRealGhostbusters'' cartoon. In a sequel, the crossovers expanded to include [[Film/Ghostbusters2016 the 2016 remake]], ''WesternAnimation/ExtremeGhostbusters'', and several video game versions.
43* The ''ComicBook/JudgeDredd'' story "Trinity" sees Dredd pulled into an {{alternate universe}}, where he has to team up with his counterparts from [[Film/JudgeDredd both]] [[Film/{{Dredd}} movies]] to catch the perp and return home.
44* ''ComicBook/MarvelZombies'' has had multiple crossovers with its SpiritualSuccessor franchise, ''ComicBook/MarvelApes''.
45* ''ComicBook/SpiderMan'':
46** ''ComicBook/SpiderVerse'' is a major example based on the Spider-Man character; promising "Every Spider-Man Ever", it's a comic book arc focused around the many different versions of the hero, joining forces in a quest to fight a villain who wants to wipe out all of them. Along with the multiple Spider-Men from comics, ranging from alternate universes, alternate timelines, alternate identities and other superheroes that also have a spider theme, they also mixed in other Spider-Men from animated and live-action series, manga and video games.
47** Among the weirder versions of the character featured in that arc, we find Spider-Man from [[WesternAnimation/SpiderMan1967 the corny 60s cartoon]], Six-Armed Spider-Man, ComicBook/SpiderHam, the pig from an alternate universe populated by {{funny animal}}s, and Takuya Yamashiro AKA [[Series/SpiderManJapan Japanese Spider-Man]], from the 70s live-action series where he has a giant robot (which he brought to the crossover) as well as [[Manga/SpiderManManga both Japanese versions from the manga]].
48** However, thanks to copyright issues, they couldn't include every version of Spider-Man as promised. In particular, the famous versions from live-action movies couldn't be shown on panel, but one Spider-Man mentions that he saw another one that looks like the guy from ''Film/{{Seabiscuit}}'', another movie by Creator/TobeyMaguire, and another one mentions one that looks the guy from ''Film/TheSocialNetwork'', another movie by Creator/AndrewGarfield.
49** Also, there's the ''ComicBook/SpiderMen'' series (2012 and 2017), in which Miles Morales meets Peter Parker from Earth-616 (before the ''ComicBook/{{Secret Wars|2015}}'' CrisisCrossover) and learns some lessons about how to be Spider-Man. This plot and ''Spider-Verse'' were combined to make the 2018 CGI movie ''WesternAnimation/SpiderManIntoTheSpiderVerse''.
50* ''Franchise/{{Transformers}}'': The ''Transformers Universe'' comic book was about Unicron abducting Autobots, Maximals, Decepticons and Predacons throughout the multiverse. The later collectors' club comics take an approach more akin to a CrossThrough, with fixed protagonists traveling through the many Transformers universes.
51[[/folder]]
52
53[[folder:Fan Works]]
54* ''Fanfic/AllAssortedAnimorphsAUs'': "What if they were all from different [=AUs=] á la Into the Spider-Verse?" has one Animorph from each official alternate universe being transported to the "prime timeline". Cassie is from book canon, Jake is from #11, Marco is from #41, Rachel is from Megamorphs #3, Ax is from Megamorphs #4, and Tobias is from the TV show.
55* ''Fanfic/ArcRoyale'' is a rare example of a fanfic author doing this with their own fics. In it, the Gods are tired of watching the stalemate between Oz and Salem, and decide it would be more interesting to have the matter settled through a combat of champions. In the supposed interest of fairness, the main combatants are all various incarnations of Jaune Arc (the weakest member of the main cast), each hailing from one of Creator/CoeurAlAran's many ''WebAnimation/{{RWBY}}'' AU fics and bonded to one of the other characters ala the ''Franchise/FateSeries''.
56* ''[[https://www.fanfiction.net/s/3293028/1/Carefree Carefree]]'' is a ''Franchise/SonicTheHedgehog'' {{crossover}} oneshot where [=SegaSonic=] canon meets ''ComicBook/SonicTheComic'' canon. Fleetway's Sonic gets stranded on [=SegaSonic=]'s Earth. He's surprised by how different their Sonic is and how more carefree he seems.
57* ''Roleplay/DarkWorldRolePlay'' (''VideoGame/{{Deltarune}}'', ''VideoGame/{{Undertale}}''): Even though the roleplay takes place mainly in Cyber World, [[spoiler: Jevil]] also has found his way into the world. There are also channels for specific [[AlternateSelf AUs]], and channels so that those [[AlternateSelf AUs]] can interact with each other.
58* ''Fanfic/{{Erutcarf}}'' is one that features nearly '''every''' Sonic continuity, including obscure ones like the French [[https://sonic.fandom.com/wiki/Sonic_Adventures#Sonic_Adventures:_Dans_Les_Griffes_De_Robotnik Sonic Adventures]] comic and the [[https://sonic.fandom.com/wiki/Virgin_Books Virgin Books]] novels. The catalyst for this being the result of Shadow and Silver attempting to fix the [[WesternAnimation/SonicPrime Paradox Prism]] before it completely shatters, only to [[GoneHorriblyRight wind up fixing it too well]] and causing it to bring various realities together instead of splitting them apart. It's stated that this is because the Paradox Prism seen here itself is a fragment of the ''original'' Paradox Prism whose shattering created multiple different dimensions/continuities, but so much time has passed since that initial shattering that the dimensions have "grown out" and stabilized, hence why bringing them back together results in not a clean remerging, but [[RealityBleed realities blending together violently and trying to force themselves out as the "dominant" one]].
59* ''[[https://www.fanfiction.net/s/14261834/1/Fractal-Chaos Fractal Chaos]]'' is a ''RWBY'' fanfic revolves around a failed experiment causing members of Team RWBY and JN_R (plus Neo) to start swapping places with versions of themselves or their friends some other timelines. Some of these alternates are from Creator/Vendetta543's other ''RWBY'' fanfics, such as ''Fanfic/AnArcForEverySeason''.
60* ''Fanfic/UltimateSonicFighters'' combines the dimensions of [[ComicBook/SonicTheComic all]] [[ComicBook/SonicTheHedgehogArchieComics three]] [[ComicBook/SonicTheHedgehogIDW major]] comic book runs, the classic and modern video games, the [[WesternAnimation/SonicUnderground three]] [[WesternAnimation/AdventuresOfSonicTheHedgehog DiC]] [[WesternAnimation/SonicTheHedgehogSatAM cartoons]], [[Manga/SonicTheHedgehog1992 a manga]], [[Anime/SonicTheHedgehogTheMovie two]] [[Anime/SonicX anime]], and the [[Film/SonicTheHedgehog2020 movies]].
61[[/folder]]
62
63[[folder:Film -- Animation]]
64* ''WesternAnimation/ScoobyDooAndTheCyberChase'' has the early-2000s version of Mystery Inc. meet virtual versions of their 1969 incarnations. Fred and Daphne comment on how their costumes have changed; Shaggy and Velma, who have changed less, not so much. The film’s villian, the Phantom Virus, also teams up with five previous monsters the gang busted in the past to fight them.
65* ''WesternAnimation/SpiderManIntoTheSpiderVerse'': Just like in ''ComicBook/SpiderVerse'', the movie is about Spider-Men from different universes landing in the home dimension of Miles Morales, fighting together to defeat the Kingpin and struggling to get back to their own dimensions. Its sequels would flip the script and have Miles team-up with other Spiders by traveling to their dimensions. The sequel, ''WesternAnimation/SpiderManAcrossTheSpiderVerse'', dials it up by including Spider-Men from previous media incarnations of the franchise, such as ''VideoGame/SpiderManInsomniac'' and ''WesternAnimation/TheSpectacularSpiderMan'' (both of whom are reprised by their original voice actors in cameo roles; Creator/YuriLowenthal and Creator/JoshKeaton respectively).
66* ''WesternAnimation/TeenTitansGoVsTeenTitans'' is a crossover between ''WesternAnimation/TeenTitans2003'' and ''WesternAnimation/TeenTitansGo'' . [[spoiler:It also has Titans from various dimensions helping both teams in the climax with the most notable versions being from the WesternAnimation/DCAnimatedMovieUniverse, the ''ComicBook/TinyTitans'' comics and even ''[[ComicBook/TeenTitans The New Teen Titans]]'' comics which the 2003 show was based on.]]
67* ''WesternAnimation/TurtlesForever'' is a textbook example, with the Franchise/TeenageMutantNinjaTurtles from [[WesternAnimation/TeenageMutantNinjaTurtles2003 the 2003 animated series]] meeting up with the Turtles from [[WesternAnimation/TeenageMutantNinjaTurtles1987 the 1987 animated series]]. The two versions of the Turtles exist in alternate dimensions and meet each other when messing with interdimensional travel. In the end, both versions meet the original Turtles from [[ComicBook/TeenageMutantNinjaTurtlesMirage the 1984 comic books]], who are presented as the prime Turtles. Erasing the existence of the 1984 Turtles would do the same to all the other versions. Also, a computer screen shows the Multiverse, which features the many dimensions populated by other versions of the Turtles like [[WesternAnimation/{{TMNT}} the 2007 CGI movie]], [[Film/TeenageMutantNinjaTurtles1990 the live-action]] [[Film/TeenageMutantNinjaTurtlesIITheSecretOfTheOoze movies from]] [[Film/TeenageMutantNinjaTurtlesIII the '90s]], and even [[Anime/TeenageMutantNinjaTurtlesLegendOfTheSupermutants the bizarre two-episode anime]]. However, missing from the screen are some {{Old Shame}}s like [[Series/NinjaTurtlesTheNextMutation the live-action TV series]] and the rock musical.
68[[/folder]]
69
70[[folder:Film -- Live-Action]]
71* ''Film/SpiderManNoWayHome'': The movie crossover between the three live-action film iterations of Spider-Man, as a result of Peter Parker accidentally causing Doctor Strange to open up TheMultiverse. This rift allows villains from the previous Creator/SamRaimi's ''Film/SpiderManTrilogy'' and the ''Film/TheAmazingSpiderManSeries'' to enter the Franchise/MarvelCinematicUniverse. Naturally, the Spider-Men from those movies then show up to allow for an AllianceOfAlternates, with all of the original actors [[RoleReprise reprising their roles]].
72* ''Film/TokumeiSentaiGobustersReturnsVsDobutsuSentaiGobusters'' revolves around an alliance between the main universe's Tokumei Sentai Go-Busters and the DenserAndWackier Dobutsu Sentai Go-Busters from an alternate universe to stop a villain, [[TheBadGuyWins whose victory]] led to the creation of the second universe.
73[[/folder]]
74
75[[folder:Live-Action TV]]
76* The 2019 ''Series/{{Arrowverse}}'' CrisisCrossover, ''Series/CrisisOnInfiniteEarths2019'', features cameos from many different versions of characters from throughout DC media, with some of them being [[AlternateSelf alternate versions]] of each other. These include the ''Series/{{Supergirl|2015}}'' Clark Kent meeting the ''Series/{{Smallville}}'' Clark Kent and later the Clark Kent from ''Film/SupermanReturns''. Meanwhile, Barry Allen from Earth-1 (''Series/TheFlash2014'') meets his Earth-90 counterpart (''Series/TheFlash1990'') along with the version from the ''Franchise/DCExtendedUniverse''.
77* ''Series/DoctorWho'':
78** The Multi-Doctor specials, where different versions of the Doctor will team up to face a common threat. More applicable to specials where the Doctor from the New Series teams up with one from the Classic Series (starting with the special "[[Recap/DoctorWho2007CiNSTimeCrash Time Crash]]"), such as "[[Recap/DoctorWho50thASTheDayOfTheDoctor The Day of the Doctor]]" and "[[Recap/DoctorWho2017CSTwiceUponATime Twice Upon a Time]]".
79** There was also the big Torchwood/Sarah Jane crossover for The Stolen Earth/Journey's End two parter on the parent show.
80* David Brent, the [[PointyHairedBoss hopeless boss]] from the British version of ''[[Series/TheOfficeUK The Office]]'', made a couple of guest appearances on [[Series/TheOfficeUS the American version]], even meeting his US counterpart Michael Scott.
81* ''Franchise/PowerRangers'':
82** Following the example of ''Franchise/SuperSentai'' below, the series has various episodes when Rangers from previous seasons (usually called as "Retro Rangers" and "Legendary Rangers"), made mostly for [[MilestoneCelebration Anniversary Specials]] of the series. The yearly tradition similar to Sentai's sadly came to an end during the Disney era, as such episodes were deemed too expensive, especially without toys to promote (the returning team being off the toy shelves by this point.
83** The 10th Anniversary Special has the "[[Recap/PowerRangersWildForceForeverRed Forever Red]]" episode in ''Series/PowerRangersWildForce'', in which Red Lion Ranger teams up with all the previous Red Rangers from past nine seasons, including Creator/JasonDavidFrank as [[Series/PowerRangersZeo Zeo Ranger V Red]].
84** The 15th Anniversary Special has the "[[Recap/PowerRangersOperationOverdriveS1E20OnceARangerPart1 Once a]] [[Recap/PowerRangersOperationOverdriveS1E21OnceARangerPart2 Ranger]]" double episode, in which the Rangers of ''Series/PowerRangersOperationOverdrive'' get replaced temporarily by (and teams up with) the team called as the "[[http://powerrangers.wikia.com/wiki/Retro_Rangers Retro Rangers]]", formed by [[Series/MightyMorphinPowerRangers Black Ranger]] (Adam Park, TheLeader), [[Series/PowerRangersNinjaStorm Blue Wind Ranger]], [[Series/PowerRangersDinoThunder Yellow Dino Ranger]], [[Series/PowerRangersSPD S.P.D. Red Ranger]] and [[Series/PowerRangersMysticForce Green Mystic Ranger]].
85** The 20th Anniversary Special has "[[Recap/PowerRangersSuperMegaforceS2EP20LegendaryBattle Legendary Battle]]" as the SeasonFinale of ''Series/PowerRangersSuperMegaforce'' in which appear '''every''' Ranger incarnation ever made in ''Power Rangers'' franchise. Also, there's [[http://powerrangers.wikia.com/wiki/The_Legendary_Battle:_Extended_Edition "The Legendary Battle: Extended Edition"]] which apart of this episode, includes the previous one that starts everything ("[[Recap/PowerRangersSuperMegaforceS2EP19TheWrath The Wrath]]") and also 43% of [[BonusMaterial extra]] [[DeletedScene footage]], all of this packed as [[DirectToVideo a DVD movie]].
86** The 25th anniversary gives us "[[Recap/PowerRangersNinjaSteelS02E10DimensionsInDanger Dimensions in Danger]]", with a villain trying to invade TheMultiverse (since ''[[Series/PowerRangersRPM RPM]]'' takes place in an alternate BadFuture and ''[[Series/PowerRangersDinoCharge Dino Charge]]'' alters history pretty drastically in its final arc, alternate universes are the excuse that lets them join in team-up occasions alongside teams in the normal universe). The main returning Rangers are [[Series/MightyMorphinPowerRangers Tommy]], [[Series/PowerRangersTimeForce Wes]], [[Series/PowerRangersRPM Gemma]], and [[Series/PowerRangersDinoCharge Koda]], each representing one of the four past eras of the franchise, with [[Series/PowerRangersTurbo Katherine]], [[Series/PowerRangersInSpace TJ]], [[Series/MightyMorphinPowerRangers Rocky]], [[Series/PowerRangersSamurai Antonio]], [[Series/PowerRangersMegaforce Gia]], and [[Series/PowerRangersDinoThunder Trent]] joining in the final battle.
87* ''Franchise/SuperSentai'':
88** The series traditionally had a team up with their previous counterparts from the previous seasons. The former does this as a late season team up movie, while the later does this as an episode that adapts footage from the movie. The Super Sentai movies also feature a quick sequence that marks the first debut of the upcoming season.
89** Special mention goes to ''Series/KaizokuSentaiGokaiger'', which features an appearance by one member of every team from all previous 34 incarnations.
90** Recently, the series has begun featuring team ups of teams from various teams with similar themes. ''Film/ZyudenSentaiKyoryugerVsGobusters'' featured team ups with the previous two dinosaur teams (''Series/KyoryuSentaiZyuranger'' and ''Series/BakuryuuSentaiAbaranger'' plus the Cameo from ''Series/ResshaSentaiToqger''). ''Series/ShurikenSentaiNinninger'' featured the return of the respected red rangers from ''Series/NinjaSentaiKakuranger'' and ''Series/NinpuuSentaiHurricaneger'' and a cameo from the red ranger of ''Series/HimitsuSentaiGoranger'' to commemorate the 40 year-to-the-day anniversary of the first episode of Super Sentai.
91* Series/UltramanTiga: While the majority of the show takes place in a separate continuity from the previous installments of the franchise, Episode 49 (The Ultra Star) features Tiga teaming up with [[Series/UltraMan the original Ultraman]] after time-travel shenanigans awaken a kaiju in the 1960s. In turn, this inspires the Neo-Frontier universe's Creator/EijiTsuburaya to create the Ultraman TV show.
92[[/folder]]
93
94[[folder:Manhua]]
95* In one strip of the ''Animation/PleasantGoatAndBigBigWolf'' manhua, Wolffy in his ''Mr. Wolffy, Mr. Right!'' design meets Sparky and Weslie in their designs from the normal show. Wolffy doesn't stick around for very long.
96[[/folder]]
97
98[[folder:Tabletop Games]]
99* ''TabletopGame/WarhammerFantasy'' and ''TabletopGame/Warhammer40000'' are no longer the same franchise, but because there are several common elements (chiefly the Chaos gods), some of their units can be used interchangeably between games.
100** The Liber Chaotica is an in-universe book written by a (Fantasy) Imperial scholar on Chaos daemons, with one section on 40K daemon engines related faithfully despite his utter lack of comprehension at what's going on.
101** Some extremely destructive weapons can occasionally be found in the Chaos Wastes (a GrimUpNorth place where the Warp intersects with reality) that can be recognized as 40K weapons such as power swords and plasma guns.
102[[/folder]]
103
104[[folder:Video Games]]
105* If it's a ''VideoGame/{{Bomberman}}'' work, chances are ''VideoGame/PowerBomberman'' has represented it in some way, mainly through characters. It doesn't just limit itself to the main series of games, either, as it also takes from the spin-offs, cancelled titles, the various manga, the two anime series (''Anime/BombermanBDamanBakugaiden'' and ''Anime/BombermanJetters''), and even promo art.
106* ''VideoGame/CastlevaniaJudgment'': The character [[VideoGame/KidDracula Galamoth]] plots to send the [[TheDragon Time Reaper]] from 10,000 years in the future into the past to destroy his rival {{Dracula}} and change history. A man named Aeon discovers this and pulls together champions from [[Franchise/{{Castlevania}} different eras of history]] into a time rift, in order to find a chosen one capable of destroying Galamoth's servant, the Time Reaper.
107* ''Franchise/FateSeries'':
108** ''VideoGame/FateGrandOrder'' pulls from all over the ''Fate'' series, including its alternate universes (''[[Anime/FatePrototype Prototype]]'' and the universe Musashi comes from, for starters), offshoot timelines (''[[VisualNovel/FateHollowAtaraxia Hollow Ataraxia]]'', ''[[VideoGame/FateExtra EXTRA]]''), and even its gag series (''Koha-Ace'' and ''[[Webcomic/LearningWithMangaFGO Learning with Manga!]]''). Unfortunately, not everyone could make it to the game, as most of the cast of ''[[Literature/FateStrangeFake strange fake]]'' is on embargo until it wraps up.
109** ''Grand Order'' incorporates the greater Franchise/{{Nasuverse}} even outside the ''Fate'' subseries; one of the first "collaboration" events of the game was with ''Literature/TheGardenOfSinners''.
110* For ''Franchise/FireEmblem'', there were ''two'' attempts to make a crossover from all over the franchise in 2017. [[VideoGame/FireEmblemWarriors One]] was a ''[[VideoGame/DynastyWarriors Musou]]''-[[HackAndSlash styled]] game featuring characters from [[VideoGame/FireEmblemShadowDragonAndTheBladeOfLight Arch]][[VideoGame/FireEmblemMysteryOfTheEmblem anea]], [[VideoGame/FireEmblemAwakening Ylisse]], [[VideoGame/FireEmblemFates Hoshido, and Nohr]] along with two girls from [[VideoGame/FireEmblemGaiden Valentia]] and [[VideoGame/FireEmblemTheBindingBlade Eli]][[VideoGame/FireEmblemTheBlazingBlade be]] respectively and a few OriginalGeneration people. [[VideoGame/FireEmblemHeroes The other]] was a gacha that has a more complex variety of characters, not only adding units from the previously mentioned worlds, but also from other worlds like [[VideoGame/FireEmblemGenealogyOfTheHolyWar Jug]][[VideoGame/FireEmblemThracia776 dral]], [[VideoGame/FireEmblemTheSacredStones Magvel]], [[VideoGame/FireEmblemPathOfRadiance Tell]][[VideoGame/FireEmblemRadiantDawn ius]], [[VideoGame/FireEmblemThreeHouses Fódlan]], [[VideoGame/FireEmblemEngage Elyos]], and even ''freaking [[VideoGame/TokyoMirageSessionsFE Tokyo]]''. This concept was revisited again in ''[[VideoGame/FireEmblemEngage Engage]]'' nearly six years later, and this time at least one character from each mainline game released up to this point take the form of spirits known as "Emblems" that inhabit rings or bracelets that fight alongside characters original to the game, while a vast majority appear as bond rings, with the added bonus that the "crossover" bit plays a major role in the game's plot.
111* While many ''Franchise/{{Gundam}}'' games are adaptations of a single work or serve as WhatIf[=/=]ExpandedUniverse material, several others are more traditional {{Crisis Crossover}}s between the various timelines, often with an ExcusePlot thrown in. Examples include the first ''Gundam Battle Assault''[[note]]which featured a Story Mode where [[Anime/MobileSuitGundamWing Heero Yuy]] faces off against various [[Anime/MobileSuitGundam Universal Century]] characters along with Treize Khushrenada and Valder Farkill (the latter hailing from the ''[[ExpandedUniverse G-UNIT/Last Outpost]]'' manga that serves as a side story to ''Wing''); the game ''Battle Assault'' was {{reformulated|Game}} [[RemadeForTheExport from]], ''Gundam: The Battle Master 2'', featured OriginalGeneration characters, whereas the first ''Battle Master'' lacked a story and ''[[VideoGame/GundamBattleAssault2 Battle Assault 2]]'' and ''Battle Assault 3'' opted for recreations of specific events for certain MS pilots[[/note]], the ''VideoGame/GundamVsSeries'' starting from ''Gundam vs Gundam'' and ''VideoGame/DynastyWarriorsGundam''.
112* ''Franchise/TheLegendOfZelda'': In ''VideoGame/HyruleWarriors'', all the playable characters in the base game of the original Wii U version that aren't legacy characters or original come from the Adult Link games: ''[[VideoGame/TheLegendOfZeldaOcarinaOfTime Ocarina of Time]]'' (original and popular), ''[[VideoGame/TheLegendOfZeldaTwilightPrincess Twilight Princess]]'' (popular) and ''[[VideoGame/TheLegendOfZeldaSkywardSword Skyward Sword]]'' (modern). There's also an entire mode dedicated to the original NES ''VideoGame/TheLegendOfZeldaI''. Eventually, through DLC and updated versions such as ''Hyrule Warriors Legends'' on the 3DS, characters from other Zelda games were added to this game, including ones from ''[[VideoGame/TheLegendOfZeldaMajorasMask Majora's Mask]]'', ''[[VideoGame/TheLegendOfZeldaTheWindWaker The Wind Waker]]'', ''[[VideoGame/TheLegendOfZeldaLinksAwakening Link's Awakening]]'', ''[[VideoGame/TheLegendOfZeldaPhantomHourglass Phantom Hourglass]]''/''[[VideoGame/TheLegendOfZeldaSpiritTracks Spirit Tracks]]'' and ''[[VideoGame/TheLegendOfZeldaALinkBetweenWorlds A Link Between Worlds]]''.
113* ''VideoGame/MarioAndLuigiPaperJam'' is an installment from the ''VideoGame/MarioAndLuigi'' series where characters from the ''Franchise/SuperMarioBros'' games meet [[VideoGame/PaperMario their paper counterparts]].
114* This is commonly seen in the ''Franchise/MegaMan'' series:
115** In some other media apart of video games, this is commonly seen when VideoGame/{{Mega Man|Classic}} meets [[VideoGame/MegaManX X]], like in an episode of the [[WesternAnimation/MegaManRubySpears Ruby-Spears American cartoon]] and in one of the ''ComicBook/MegaManArchieComics'' comics.
116** In ''VideoGame/MegaManII'', there's Quint, a Mega Man from the future who was brought to the present and modified by Dr. Wily to be one of "Mega Man Killers", who also returns in future games of the Classic franchise.
117** Also seen in various of ''VideoGame/CapcomVs'' games in which various Mega Man versions (or characters from different game series) can be seen together, like ''VideoGame/SNKVsCapcomCardFightersClash'' series in which you can see Character Cards of all ''Mega Man'' games in the same deck. Another good example is ''VideoGame/TatsunokoVsCapcom'', in which [[VideoGame/MegaManLegends Rock Volnutt]] is present alongside [[VideoGame/MegaManClassic Roll]] (and, in ''[[UpdatedRerelease Ultimate All-Stars]]'', [[VideoGame/MegaManX Zero]]) despite the wide gaps in time between their respective series.
118** ''Rockman.EXE Operate Shooting Star'' is a Japan-only Platform/NintendoDS remake of the first ''VideoGame/MegaManBattleNetwork'' with an added chapter in which Geo Stelar of ''VideoGame/MegaManStarForce'' travels back in time and teams up with his predecessors.
119** A literal example is seen in ''VideoGame/SuperSmashBrosForNintendo3DSAndWiiU'', in which the original Mega Man is a GuestFighter, and his [[LimitBreak Final Smash]] is a CombinationAttack in which [[LegacyCharacter various other Blue Bombers]] (X, Rock Volnutt, [[VideoGame/MegaManBattleNetwork MegaMan.EXE]] and [[VideoGame/MegaManStarForce Mega Man/Omega-Xis]]) appear alongside him to [[AllYourPowersCombined fire a joint Charge Shot together]]. This was retained for the next game in the series, ''VideoGame/SuperSmashBrosUltimate'', only with the addition of [[AloofOlderBrother Proto Man]] and [[TheRival Bass]] from the Classic series.
120* Commonly seen in ''VideoGame/{{MUGEN}}'', in which you can make the roster as you like, so you can put the same character from different games in the same created fighting game you like. As example, you can put [[Franchise/StreetFighter Ryu]] from ''VideoGame/StreetFighterII'', ''VideoGame/StreetFighterAlpha'', the ''VideoGame/MarvelVsCapcom'' series, the ''[[VideoGame/SNKVsCapcom Capcom vs. SNK]]'' series, ''VideoGame/SNKVsCapcomSVCChaos'', and even the original ''VideoGame/StreetFighterI'' in the same roster and make them fight against each other.
121* ''Franchise/{{Persona}}'':
122** ''VideoGame/Persona4Arena'' is a FightingGame sequel to the events of ''VideoGame/Persona4'' wherein the Investigation Team crosses paths with a few former members of [[VideoGame/Persona3 S.E.E.S.]] (Mitsuru, Akihiko, and Aigis), now calling themselves the Shadow Operatives, as well as Elizabeth, the third game's Velvet Room attendant. Where this trope really kicks in is the sequel, ''VideoGame/Persona4ArenaUltimax'', which sees not only the majority of the other ''Persona 3'' party members return to action (though Fuuka remains on the sidelines, unlike fellow SupportPartyMember Rise), but several [[NonPlayerCharacter NPCs]] from ''Persona 4'' (''[[UpdatedRerelease Golden]]'') get PromotedToPlayable, accounting for most of the [[spoiler:still living]] major players in ''P3'' and ''P4''. [[spoiler:And even then, it turns out that Ikutsuki, the MoleInCharge for S.E.E.S., [[VillainousLegacy is responsible for one of the main antagonists]] and gets several fakes in his likeness to cameo throughout ''Ultimax'' despite being confirmed dead.]] Unlike the ''Persona Q'' titles below, this duology is canon.
123** ''VideoGame/PersonaQShadowOfTheLabyrinth'' is a non-canon game featuring the playable characters from ''VideoGame/Persona3'' and ''VideoGame/Persona4''. Oddly, despite the original games being only a few years apart in places so close that characters from ''4'' have visited the setting of ''3'', this game still had to resort to [[TimeyWimeyBall Timey-Wimey shenanigans]] due to [[spoiler:the protagonist's death at the end of ''Persona 3'']]. [[spoiler:Once the RealityBreakingParadox that brought both groups together is dealt with, they return home without any knowledge of what happened, hence why no one recognizes each other during the events of ''VideoGame/Persona4Arena''.]]
124** Its sequel, ''VideoGame/PersonaQ2NewCinemaLabyrinth'', reunites the ''P3'' and ''P4'' casts on top of bringing in [[VideoGame/Persona5 the Phantom Thieves of Hearts]] ''and'' the female protagonist exclusive to ''Persona 3 [[Platform/PlayStationPortable Portable]]'' (who is implied to be an AlternateSelf to [[CuttingOffTheBranches her mainline counterpart]]). While the same Timey-Wimey shenanigans ensue [[spoiler:once again to get around the ''P3'' protagonist's canonical death (as well as the fact that ''P5'' is at least a few years further along in the timeline than ''P4'' was)]], [[spoiler:Joker, the PlayerCharacter of ''5'' and ''Q2'', appears to be the ''only'' person outside of the Velvet Room attendants to exhibit RippleEffectProofMemory after returning to his time, as he recognizes [[OriginalGeneration Hikari]] while attending a high school film festival in the epilogue]].
125* ''Franchise/{{Pokemon}}'': The "core" games are generally treated as one continuity, the long-running ''[[Anime/PokemonTheSeries Pokémon]]'' anime another, and each "spinoff" game its own separate [[{{Pun}} pocket]] universe. This doesn't stop the anime from periodically passing through other continuities, though:
126** ''VideoGame/PokemonRedAndBlue'': Despite being a canon game, the third of the trio, ''Special Yellow Pikachu Edition'', uses the anime designs instead of the ones from ''Red'' and ''Blue''/''Green''. This includes replacing the generic Team Rocket grunts with Jessie and James (and Meowth). The main character is locked into a Pikachu as a starter instead of being able to choose from Bulbasaur/Charmander/Squirtle (but later can obtain them anyway), like Ash did in the anime, and starting off the rival with Eevee, just like Gary did.
127** ''VideoGame/PokemonSunAndMoon'': Special "Ash's Cap" Pikachus were given out for the 20th anniversary of the franchise, as well as for a tie-in with the ''[[Anime/PokemonIChooseYou I Choose You!]]'' movie. Meanwhile, a Greninja with the Ash-Greninja ability from the anime was given out as a thank-you for playing the game's demo. These Pokémon also showed up in ''Pokémon Shuffle'' and ''Tretta''.
128** ''VideoGame/PokemonMasters EX'': In addition to being a crossover between all the core series games [[VideoGameLongRunners up to that point]] (2019) and beyond (complete with characters either explicitly confirmed to hail from {{Alternate Universe}}s, such as the ''[[VideoGame/PokemonUltraSunAndUltraMoon US/UM]]'' versions of [[VideoGame/PokemonRedAndBlue Giovanni]] and [[VideoGame/PokemonDiamondAndPearl Cyrus]], or characters implied to be [[AlternateSelf AU variants of one another]], such as [[VideoGame/PokemonRedAndBlue Leaf]] and [[VideoGame/PokemonLetsGoPikachuAndLetsGoEevee Green]]), the game featured special collaboration events with the anime, bringing in Ash and Jessie & James as playable characters. Furthermore, while Ash is indicated to have arrived in Pasio at some point during the events of ''[[Anime/PokemonJourneysTheSeries Journeys]]'', Jessie & James instead hail from the {{alternate|Continuity}} film continuity that began with ''I Choose You!'', being pulled from around the time of ''[[Anime/PokemonSecretsOfTheJungle Secrets of the Jungle]]''.
129* ''VideoGame/PowerRangersBattleForTheGrid'' features a host of characters from across [[Franchise/PowerRangers the franchise]] (including a villain from the [[ComicBook/MightyMorphinPowerRangersBoomStudios comic book adaptation]] that had never appeared in the series proper).
130* ''Franchise/SonicTheHedgehog'':
131** ''VideoGame/SonicGenerations'':
132*** The game features the modern Sonic from the [[Platform/SegaDreamcast Dreamcast]] era, who was redesigned with green eyes, longer legs and smaller belly, meeting through time travel the classic Sonic from the [[Platform/SegaGenesis Genesis/Mega Drive]] era, who is pudgy, has black eyes and short legs, and also [[TheVoiceless never talks]].
133*** The gameplay is divided between the two characters, the Classic Sonic levels are played just like the Genesis 2D platformers but with 3D graphics, while the Modern Sonic levels are similar to ''VideoGame/SonicUnleashed'' and ''VideoGame/SonicColors'', having 3D gameplay but some 2D sections, but in those 2D sections, Modern Sonic can use moves that his classic counterpart can't.
134*** The game features levels based on all main series games, dividing them up into three categories, Classic (Genesis/Mega Drive era), Dreamcast (which includes ''VideoGame/SonicHeroes'') and Modern (''[[VideoGame/SonicTheHedgehog2006 Sonic '06]]'' and onward). Back are iconic level themes like [[VideoGame/SonicTheHedgehog1 Green Hill Zone]] and [[VideoGame/SonicTheHedgehog2 Chemical Plant Zone]], and also modern levels like [[VideoGame/SonicAdventure2 City Escape]] and [[VideoGame/SonicHeroes Seaside Hill]], and all levels are divided in two parts for the two characters, modern levels and their gimmicks are adapted for the pure 2D classic gameplay, and classic levels are adapted with gimmicks from the 3D games for the modern gameplay.
135*** Each Era has its own boss fights too; there is the final boss of ''VideoGame/SonicTheHedgehog2'' fought by Classic Sonic, and Perfect Chaos (''VideoGame/SonicAdventure'') and Egg Dragoon (''Sonic Unleashed'') fought by Modern Sonic, the 3DS version has different bosses, and there's also rival battles, with Metal Sonic being the first and fought by Classic Sonic, Shadow and Silver being the second and third and fought by Modern Sonic.
136*** The FinalBoss is [[spoiler:both Classic and Modern Sonic uniting themselves and using the Chaos Emeralds to fight the Time Eater, controlled by Modern Dr. Eggman and Classic Dr. Eggman, the latter of which is called Dr. Robotnik by Classic Tails, [[LampshadeHanging prompting him to point out no one calls him that anymore]].]]
137** Classic Sonic and Modern Sonic once again team up in the sequel game ''VideoGame/SonicForces'', the [[VideoGame/SonicMania other part]] of the [[MilestoneCelebration 25th anniversary celebration]] of the franchise, in which the player can choose between three different styles: Classic Sonic style, Modern Sonic style, and an [[PlayerCharacter Avatar]] style, a mode in which the player can create their own character. However, ''Forces'' seemingly retcons ''Generations'' by stating that Classic Sonic is not Sonic from the past, and is instead another Sonic from [[AlternateUniverse another dimension]], [[FanDislikedExplanation something fans weren't pleased to learn]]. However, Creator/IanFlynn would assure fans that the Classic and Modern eras are all one timeline rather than [[AlternateTimeline a new splitting of timelines]] through TimeTravel, brushing off that dialogue as potential translation error.
138* ''Franchise/SpiderMan'':
139** ''VideoGame/SpiderManShatteredDimensions'', a game in which you can manage Spider-Men from different alternate realities, the [[Franchise/MarvelUniverse mainstream one]] (Peter Parker), [[ComicBook/SpiderManNoir Noir one]] (also Peter Parker), [[ComicBook/SpiderMan2099 Marvel 2099 one]] (Miguel O'Hara) and [[ComicBook/UltimateSpiderMan Ultimate one]] ([[RuleOfThree Peter Parker once again]]), to find a shattered cosmic MacGuffin and stop their respective villains from using the pieces to become immensely powerful.
140** There was a follow-up called ''VideoGame/SpiderManEdgeOfTime'', although this one was only about the mainstream one and the Marvel 2099 one working together to prevent the death of the former from happening, which somehow caused Alchemax from the Marvel 2099 reality to TakeOverTheWorld.
141* The ''VideoGame/SuperSmashBros'' series is about multiple franchises crossing over, but some examples fit the trope:
142** Just like in ''VideoGame/HyruleWarriors'', the ''Franchise/TheLegendOfZelda'' franchise has multiple characters from different eras. In ''[[VideoGame/SuperSmashBros64 Smash 64]]'' and ''[[VideoGame/SuperSmashBrosMelee Melee]]'', Link, Zelda, Sheik, Young Link and Ganondorf are based on their ''[[VideoGame/TheLegendOfZeldaOcarinaOfTime Ocarina of Time]]'' designs. ''[[VideoGame/SuperSmashBrosBrawl Brawl]]'' and ''[[VideoGame/SuperSmashBrosForNintendo3DSAndWiiU 3DS/Wii U]]'' change them to their ''[[VideoGame/TheLegendOfZeldaTwilightPrincess Twilight Princess]]'' designs, but Young Link is replaced with Toon Link from ''[[VideoGame/TheLegendOfZeldaTheWindWaker The Wind Waker]]''. ''[[VideoGame/SuperSmashBrosUltimate Ultimate]]'' embraced the multiple eras, as Link has his ''[[VideoGame/TheLegendOfZeldaBreathOfTheWild Breath of the Wild]]'' design (with Sheik having a ''Breath of the Wild''-based design, despite not being in that game), Ganondorf and Young Link use their N64 designs, Zelda has a design based on ''[[VideoGame/TheLegendOfZeldaALinkToThePast A Link to the Past]]'' and ''[[VideoGame/TheLegendOfZeldaALinkBetweenWorlds A Link Between Worlds]]'', while Toon Link of course represents ''The Wind Waker'' again. The series also has many [[AssistCharacter Assist Trophies]], stages and music from different ''Zelda'' games that don't have a playable fighter.
143** ''Franchise/FireEmblem'' has multiple playable protagonists from across the series in the roster; for its debut in ''Melee'', Marth from ''[[VideoGame/FireEmblemShadowDragonAndTheBladeOfLight Shadow Dragon]]'' and Roy from ''[[VideoGame/FireEmblemTheBindingBlade The Binding Blade]]'' were implemented as newcomers. ''Brawl'' would drop Roy, but keep Marth and bring in Ike from ''[[VideoGame/FireEmblemPathOfRadiance Path of Radiance]]'' and ''[[VideoGame/FireEmblemRadiantDawn Radiant Dawn]]''. The next instalment, ''for 3DS/Wii U'', would bring back Marth and Ike while adding Robin and Lucina from ''[[VideoGame/FireEmblemAwakening Awakening]]'', then reintroduce Roy as DLC and also bring in Corrin from ''[[VideoGame/FireEmblemFates Fates]]'' as one of the last downloadable fighters. ''Ultimate'' would bring all of them back, while also introducing Chrom from ''Awakening'' in the base game and Byleth from ''[[VideoGame/FireEmblemThreeHouses Three Houses]]'' as DLC. Like ''Zelda'' above, it also has secondary content from other games without a fighter.
144** The only playable character from the ''Franchise/MegaMan'' franchise is VideoGame/{{Mega Man|Classic}} from the Classic series, but his Final Smash features X from ''VideoGame/MegaManX'', [=MegaMan=] Volnutt from ''VideoGame/MegaManLegends'', [=MegaMan.EXE=] from ''VideoGame/MegaManBattleNetwork'', and Star Force Mega Man from ''VideoGame/MegaManStarForce''. ''Ultimate'' added Proto Man and Bass to said Final Smash, and the game also has Zero from ''Mega Man X'' as an Assist Trophy.
145** For ''Franchise/{{Castlevania}}'', ''Ultimate'' introduced both Simon Belmont, [[VideoGame/CastlevaniaI from the original game in the series]], and Richter Belmont, from ''[[VideoGame/CastlevaniaRondoOfBlood Rondo of Blood]]'', as playable fighters, with Alucard also appearing as an Assist Trophy deliberately designed after his ''[[VideoGame/CastlevaniaSymphonyOfTheNight Symphony of the Night]]'' incarnation. Likewise, there's various music tracks and Spirits of characters from multiple games in the series.
146** The ''Franchise/DragonQuest'' franchise has four different heroes from four different games in one fighter slot: Luminary from ''VideoGame/DragonQuestXI'', Erdrick from ''VideoGame/DragonQuestIII'', Solo from ''VideoGame/DragonQuestIV'', and Eight from ''VideoGame/DragonQuestVIII''. Luminary is the main character, and the other three work as alternate costumes.
147** {{Subverted|Trope}} with ''VideoGame/XenobladeChronicles''. While [[VideoGame/XenobladeChronicles1 the first game]] and ''[[VideoGame/XenobladeChronicles2 2]]'' can be enjoyed as standalone adventures and the representatives from each in ''Smash'' (Shulk for the first game and Pyra/Mythra for ''2'') don't meet each other canonically in the series proper (they do get crossover DLC in ''2''), the big twist of ''2'' is that their respective worlds were split apart from each other and that their adventures are happening [[SimultaneousArcs simultaneously]]. Not only that, but ''VideoGame/XenobladeChronicles3'' drops all pretenses of this being a spoiler of any kind by explicitly being set in the future of both worlds and having characters from both meet each other, albeit not Shulk and Pyra/Mythra.

150[[folder:Western Animation]]
151* The ''WesternAnimation/AlvinAndTheChipmunks'' episode spoofing ''Film/BackToTheFuture1'' has the 1980s Chipmunks meeting their 1960s counterparts from ''WesternAnimation/TheAlvinShow''.
152* The final episode of ''WesternAnimation/Ben102016'' was ''Alien X-Tinction'', a one-hour special that had Ben team up with the all the differently aged versions of himself from the "Classic" continuity, as well as [[WhatIf the version of Gwen]] who got the TransformationTrinket instead.
153* An InUniverse example happens in ''WesternAnimation/TheFairlyOddParents''. In the episode "The Crimson Chin meets Mighty Mom and Dyno Dad", the Crimson Chin meets several wildly different versions of his EraSpecificPersonality, from the '30s pulp-fiction Chin, to the "super-edgy" 1985 Chin, who got cancelled for swearing.
154* The ''WesternAnimation/JusticeLeague'' episode "Legends" was [[WhatCouldHaveBeen initially intended]] to feature the ComicBook/JusticeSocietyOfAmerica. [[ExecutiveMeddling The rights weren't cleared]] (possibly because the superheroes involved were portrayed as [[InnocentBigot somewhat bigoted]]), so the writers instead used a CaptainErsatz version called "The Justice Guild".
155* ''WesternAnimation/TheSimpsons'':
156** In one version of the CouchGag, the Simpsons run in and find the original versions of themselves already sitting there.
157** In "[[Recap/TheSimpsonsS7E18TheDayTheViolenceDied The Day the Violence Died]]", the day is saved by Lester and Eliza, who are basically the Bart and Lisa from ''Series/TheTraceyUllmanShow'' shorts.
158** In the [[Recap/TheSimpsonsS14E1TreehouseOfHorrorXIII thirteenth]] ''WesternAnimation/TreehouseOfHorror'' episode, Homer makes clones of himself during the segment "Send in the Clones". After the clones cause trouble, Homer attempts to abandon them and the hammock that created them, but the clones just use the hammock to create even more clones; one of the degraded clones looks like Homer from the early ''[[Series/TheTraceyUllmanShow Tracey Ullman Show]]'' shorts, who says "Let's all go out for some frosty chocolate milkshakes!"
159** In a later ''Treehouse of Horror'' segment ([[Recap/TheSimpsonsS26E4TreehouseOfHorrorXXV XXV]]'s "The Others"), the Simpsons are haunted by the ghosts of the ''Tracey Ullman''-era Simpsons. The ending of that segment featured various derivatives of the family wanting to move into the Modern Simpsons' house after they were killed. Most of the alternate Simpsons were created specifically for this scene, but three previous versions do make an appearance here -- the "Island of Dr. Hibbert" ("[[Recap/TheSimpsonsS14E1TreehouseOfHorrorXIII Treehouse of Horror XIII]]") Simpsons in their animal forms (Panther Marge, Spider Bart, Aardvark Maggie, Owl Lisa, and Walrus Homer), the [[BuiltWithLEGO LEGO Simpsons]] from "[[Recap/TheSimpsonsS25E20BrickLikeMe Brick Like Me]]", and Creator/SylvainChomet's version of the Simpsons from "[[Recap/TheSimpsonsS25E12Diggs Diggs]]"' CouchGag.
160* ''Franchise/SpiderMan'':
161** ''WesternAnimation/SpiderManTheAnimatedSeries'' has the "Spider Wars", which (along with the later ''VideoGame/SpiderManShatteredDimensions'', mentioned in the Video Games section) actually inspired the ''ComicBook/SpiderVerse'' comic book storyline. Here, Madame Web (and later the Beyonder) first recruited Spider-Man from the main universe of the series and later recruited various alternate versions of him, including [[https://marvel.fandom.com/wiki/Spider-Armor_MK_I Armored Spider-Man]] (a kind of "[[ComicBook/IronMan Tony Stark]]" version of Peter Parker), Six-Armed Spider-Man (a mutated version of him that permanently has six arms, seen in comics and the same series but GoneHorriblyWrong), Spider-Man with ComicBook/DoctorOctopus' arms (predating ''ComicBook/{{Superior Spider|Man2013}}-Man'' by decades), Spider-Man [[Creator/TobeyMaguire as]] [[Creator/AndrewGarfield an]] [[Creator/TomHolland actor]], and even the ComicBook/ScarletSpider (Ben Reilly as in ''ComicBook/TheCloneSaga''). This group is simply named the ''[[https://marvel.fandom.com/wiki/Spider-Men_(Multiverse) Spider-Men]]''.
162** ''WesternAnimation/{{Ultimate Spider|Man2012}}-Man'' did its third season serve as this, having Peter interact with Noir, Spider-Ham, 2099, Spyder-Knight, Spider-Girl (in this case, a GenderFlip version of him named Petra Parker), and Miles Morales (who made his animated debut with this show). It even got a sequel in which the obscure Blood-Spider and Spider-Gwen (likewise making her animated debut here) got to join the fun.
163* ''WesternAnimation/TeenageMutantNinjaTurtles2012'' did something similar to ''WesternAnimation/TurtlesForever'', with an episode crossing over with [[WesternAnimation/TeenageMutantNinjaTurtles1987 the 1987 cartoon]] with a plot similar to ''Turtles Forever''. Since the 1987 cartoon was hand-drawn but the 2012 cartoon was CGI, the episode uses ArtShift, alternating between hand-drawn animation and CGI depending on which universe the scene takes place, and converting the look of the Turtles in the process. For some reason, 1987 and 2012 Donatello stay in their original 2D and 3D forms when they enter [[ComicBook/TeenageMutantNinjaTurtlesMirage the 1984 comic universe]], even having colors when the whole comic book world is black and white.
