Ah, the IntercontinuityCrossover fight. Everyone wonders once in awhile "If X and Y met, who would win in a fight?" And whether you [[FanWank come up with incredibly thorough theories of your own]], [[FandomRivalry argue it with others]], write a {{fanfic}}, or just [[MyDadCanBeatUpYourDad resort to name-calling]], everyone has their own opinion.

Such bouts between characters from different works will often involve [[TrappedInAnotherWorld one or more of the fighters being pulled into a different continuity]], [[LetsYouAndHimFight the strangers fighting for no logical reason]] and [[PowerCreepPowerSeep handicaps or caveats being introduced to make the fights more interesting]]. Also usually ends with [[PopularityPower the most popular of the combatants winning]], or [[EvasiveFightThreadEpisode no one winning at all]].

The trope is named for the song and flash animation "[[Music/TheUltimateShowdownOfUltimateDestiny The Ultimate Showdown of Ultimate Destiny]]" by Lemon Demon, in which nearly every famous fictional character, pop culture icon and historical personage ''ever'' come together for the sole purpose of knocking the living crap out of each other. [[spoiler: (The last one standing is [[MisterRogersNeighborhood Mister Rogers]].) ]]
Overlaps with MassiveMultiplayerCrossover when more than 2 works are involved. If the characters end up in a relationship instead of fighting, it's a CrossoverShip. Compare to CharacterTiers and GuestFighter. Contrast with StoryBreakerTeamUp.

'''If you were looking for the song, [[Music/TheUltimateShowdownOfUltimateDestiny go here]].'''

!!Examples:
[[foldercontrol]]

[[folder: Anime and Manga ]]
* ''{{Mai-Otome}}'': Put the Otome against the [=HiME=], or, more specifically, their resurrected ''{{Mai-HiME}}'' counterparts.
* ''GundamBuildFighters'' features several models from different series, many of which are modified, fighting it out. So you have situations like the Build [[GundamSeed Strike]] vs. the [[GundamX GX]] Maoh. Heck, the initial episode where these two "fight" has the builders dressed up as Kira and Garrod respectively.
[[/folder]]

[[folder:Comics]]
* ''[[ComicBook/BatmanVampire Batman and Dracula: Red Rain]]'': finally put to rest an age-old debate: The Dark Knight or the Prince of Darkness? Dracula and Batman fight over Gotham City to find out who the true master of fear and deception is.
* Dracula vs. Superman: By hypnotizing Lois, Dracula actually gained the upper hand and succeeded in drinking Superman's blood. However, Superman is solar powered, and seconds after drinking his blood well... [[YourHeadASplode imagine eating a grenade]].
* [[http://www.dialbforblog.com/archives/315/ Superman vs. Muhammad Ali]]
* ''Comicbook/FreddyVsJasonVsAsh''
* Franchise/{{Alien}} vs. Franchise/{{Predator}} vs. Franchise/{{Terminator}}
* [[TheDarkKnightReturns Superman vs. Batman]] [[spoiler:Batman wins]]
** [[http://www.comicvine.com/profile/citizenbane/blog/superman-vs-batman/79268/ Or would he?]]
* Then there's one in ''[[ComicBook/SupermanBatman Superman/Batman]]'' issue 78, which handled the subject masterfully. The fight happens, but suddenly you see a narration, or rather, two narrations arguing against each other. Eventually, it is shown that two kids, one a fan of Superman and the other a fan of Batman, arguing who wins. After much {{Ass Pull}}s done with each argument, [[spoiler:the two kids agreed that the two are friends and would not fight each other]].
** Towards the end, we see Superman and Batman observing the kids. Superman wonders who would win and asks Batman on what he thinks, but Batman just flies away. [[spoiler:Batman believes Superman will win]].
* DoctorDoom vs. {{Magneto}}
[[/folder]]

[[folder:Fan Works]]
* This is the entire premise of ''Fanfic/MyLittlePonyVs''.
* ''Fanfic/FantasyOfUtterRidiculousness'' asks the question: "Who would win in a fight between [[WesternAnimation/MegasXLR Megas]] and [[VideoGame/{{Touhou}} Suika Ibuki]]?" [[spoiler: The answer: Marisa Kirisame.]]
* ''Webcomic/RichsComixBlog'' has a story that pits [[Series/ForeverKnight LaCroix]] against [[Series/DoctorWho the Master]]. Another story pits the [[Series/DoctorWho Daleks]] against some [[Film/{{Alien}} Xenomorphs]].
[[/folder]]

[[folder:Film]]
* ''Film/TheAvengers'': Thor vs. Iron Man, with Captain America joining in at the end, and we get to see Mjolnir vs. Captain America's shield. Thor vs. The Hulk.
* ''MegaSharkVsGiantOctopus'': ExactlyWhatItSaysOnTheTin, and [[http://www.youtube.com/watch?v=2LpjxWF7C6E Vs. R. Lee Ermey]], [[spoiler: with a cameo from Creator/BillyMays.]]
* ''Jungle Drums'': a 1953 wilderness-adventure film crew stages a fight between a tiger and a lion.
* ''TheForbiddenKingdom'': JetLi vs. JackieChan. It was a draw, though Jet Li has gone on record as saying that in a no holds barred fight, Jackie would wipe the floor with him.
* ''Series/{{Star Trek|The Original Series}}'': Had an episode in which aliens set up an Ultimate Showdown: Kirk, Spock, Abraham Lincoln, and Surak versus Colonel Green, Kahless, Zora, and GenghisKhan.
* ''Film/AlienVsPredator'' and ''AliensVsPredatorRequiem''
* ''Film/KingKongVsGodzilla''
* ''Film/FreddyVsJason''
* ''Film/FrankensteinMeetsTheWolfMan'', the very first Famous Monster vs Famous Monster movie. Universal then did two more, adding Dracula to make it a Triple Threat.
* ''Film/WayOfTheDragon'': BruceLee vs. ChuckNorris. Bruce wins in the movie. Norris, like Li above, says that Lee would have destroyed him had they fought for real.
[[/folder]]

[[folder:Literature]]
* "Shark vs. Train": Parodied in the children's book which takes the more common sense approach, with hilarious results (it matters, for instance, whether the competition is under water, or involves trying to sell lemonade.)
* 1906: ''[[Literature/ArseneLupin Arsène Lupin]] vs. SherlockHolmes'', by Lupin's author Maurice Leblanc, as an AffectionateParody. Soon afterwards, Arthur Conan Doyle complained and, from the following edition onwards, the story became ''Arsène Lupin vs. [[WritingAroundTrademarks Herlock Sholmes]]'' (or, in some versions, "Holmlock Shears").
* ''Literature/{{Animorphs}}'': huge fanboys Jake and Marco from like to argue about whether Batman could beat Spider-Man.
* OlderThanDirt: TheIliad is this to a significant portion of [[ClassicalMythology Greek mythology]], including the gods themselves.
** It also makes clear that Zeus would win with one arm behind the back if he decided to join the frame (so he claims, and the gods, ''speaking from experience'', don't dare to contradict him)... [[BigNeutral And that's why he stays out of it]].
* And how about David Weber's [[Literature/OutOfTheDark Out of The Dark]] and [[spoiler:vampires versus aliens]]? And that's just the first part of the trilogy!
[[/folder]]

[[folder:Live Action TV]]
* In ''Series/HowIMetYourMother'', Barney, Marshall and Lily go to the event "Wrestlers Vs. Robots" where Mexican-style wrestlers battle a variety of robots.
* ''DeadliestWarrior'': A Spike TV show which explores "history's greatest killing machines", look at their historic backgrounds and the science behind their equipment and fighting styles, and pair them off in a one-on-one computer simulated fight. Showdowns include "Gladiator vs. Apache", "Ninja vs. Spartan", "Taliban vs. IRA", "Yakuza vs. Mafia", and "William Wallace vs. Shaka Zulu".
* ''Jurassic Fight Club'': A History Channel show, similar to ''Deadliest Warrior'' in that it uses best available knowledge to establish the abilities, strengths, and weaknesses of the animals, then [=CGIs=] the actual fights. Match-ups include Allosaurus vs. Ceratosaurus; Mega-Lion vs. the Short-Faced Bear; and Megalodon vs. Brygmophyseter, the "biting sperm whale".
* Animal Planet had a short lived series ''Animal Face Off'', which was basically ''Jurassic Fight Club'' done with living species that plausibly might confront one another in the wild.
* ''Series/HarryHillsTVBurp'': "Well, I ''like'' X, but then I ''also'' like Y. But which is better?" ''[Costumed/made-up/bewigged representations/impersonators of X and Y crash into studio from opposite directions and make a beeline for each other]'' "FIIIIIIIIIIIGHT!!"
* ''Series/DoctorWho'':
** The original series episode "The Mind Robber" eventually, through convoluted means, features a sword fight that involved Cyrano de Bergerac, D'Artagnan, Blackbeard, and Sir Lancelot.
** And "Doomsday" brings the fight people had been wanting for ''decades''; Daleks vs Cybermen.
** The novel "All-Consuming Fire" had Sherlock Holmes and the seventh Doctor square off with the Cthulhu Mythos.
* ''SaturdayNightLive'': Spoofed in a recurring sketch in which George Wendt leads a cadre of football fans who speculate on the scores of hypothetical games pitting the Chicago Bears against other teams, with the Bears facing increasingly unlikely handicaps, such as being shrunk to the size of midgets. (Hint: Da Bears win.)
-->'''Wendt''': Who would win, the Death Star or the Enterprise?
-->'''Others''': Ditka!
* SuperSentai do this about once a year [[BigDamnMovie as a movie]], usually by having the current SuperSentai meet up with the previous year's SuperSentai in a LetsYouAndHimFight scene before teaming up to take on the BigBad of the film.
** ''Series/SamuraiSentaiShinkenger'' met up with ''Series/TensouSentaiGoseiger'' for a movie in 2011.
** ''Series/KaizokuSentaiGokaiger'' then met up with ''Series/TensouSentaiGoseiger'' before taking on ''Series/SpaceSheriffGavan'' and going on to fight ''Series/KamenRiderDecade'', the last done '''two months after their own series ended.'''
** ''Film/KamenRiderXSuperSentaiSuperHeroTaisen'' pits the Kamen Riders (led by Decade) against the Sentai warriors (led by [=GokaiRed=]). ''Series/KamenRiderFourze'' and the ''Series/TokumeiSentaiGoBusters'' eventually pop up and [[EvasiveFightThreadEpisode ask why they're even fighting in the first place]].
* ''Series/KamenRiderDecade'': For the ''Franchise/KamenRider'' series. Decade can take on the form and powers of the last nine hero Riders, allowing match-ups like Kuuga vs. Kiva, Kiva vs. Knight and so on.
* ''Series/{{Angel}}'': In one episode, Angel and Spike argue vehemently over who would win if astronauts and cavemen got into a fight.
-->'''Wesley''': Ah. You've been yelling at each other for 40 minutes about this? ...do the astronauts have weapons?
-->'''Angel''' and '''Spike''' (in unision): [[SeriousBusiness NO!]]
** Even better, they somehow manage to get all of the other main characters at the time to argue over this. Through the entire episode.
* One episode of ''GameOfThrones'' opens with [[PunchClockVillain two Lannister soldiers]] discussing who's the best fighter in Westeros. They've narrowed it down to Ser Jaime [[RedBaron "Kingslayer"]] Lannister, Ser Gregor [[NamesToRunAwayFromReallyFast "The Mountain"]] Clegane, and Ser Loras [[AgentPeacock "The Knight of Flowers"]] Tyrell. Their discussion is cut short by [[spoiler:the Stark army]].
--> ''What about Loras Tyrell?''
--> ''He's been [[UnusualEuphemism stabbing]] Renly Baratheon for years, and Renly ain't dead!''
* ''Series/BuffyTheVampireSlayer'' had an episode called "Buffy vs. {{Dracula}}". The titular fight ends inconclusively, with Buffy killing the Count, but with him clearly able to come BackFromTheDead at will. The show also had to break many of its [[MagicAIsMagicA own rules]] about [[OurVampiresAreDifferent how its vampires work]] [[labelnote:*]] though season 8 reveals his powers are a result of his skill in magic.[[/labelnote]] in order to pit Buffy against a recognizable version of Dracula; the whole episode relied heavily on RuleOfCool.
* Discussed in ''Series/TheBigBangTheory'' when the guys [[CavemenVsAstronautsDebate argue over]] which fictional characters, mostly superheroes, would best who in a fight.
[[/folder]]

[[folder:Music]]
* Defied in Ookla the Mok's "Stop Talking About Comic Books or I'll Kill You":
--> I don't care if the {{Hulk}} could defeat [[{{Superman}} the Man of Steel]]\\
I'm gonna rearrange your face if you continue to debate\\
Whether [[{{Wolverine}} Logan's]] claws could pierce [[CaptainAmerica Steve Rogers]]' shield
[[/folder]]

[[folder:Video Games]]
* ''DissidiaFinalFantasy'': The game, and 012 pit the lead characters from the first ten FinalFantasy titles against each of their respective arch-foes from their respective worlds with the fate of TheMultiverse at stake.
* ''{{Scribblenauts}}'': allows for a nearly infinite number of these. Bigfoot versus Longcat, God + Shotgun + Skateboard versus Cthulhu, [[MemeticMutation T. Rex versus Robot Zombies...]] The fourth video found [[http://www.1up.com/do/previewPage?cId=3175442 here]] takes this to absurd lengths.
* {{MUGEN}}: A custom FightingGame system which allows characters from different fighting games to battle aginast each other. It's gotten popular on Website/YouTube, especially [[Anime/DragonBallZ Perfect Cell]] vs. [[Manga/JoJosBizarreAdventure Dio Brando]], where Dio wins using his famous steam roller attack.
* CapcomVsWhatever: The [[IntercontinuityCrossover Intercontinuity]] MassiveMultiplayerCrossover FightingGame series where a bunch of unconnected Capcom properties and unconnected properties from another company come together to see who's the best.
* ''WarriorsOrochi'': Koei's video game crossover between their Three Kingdoms China ''DynastyWarriors'' and their Sengoku Japan ''SamuraiWarriors'' franchises. By ''Warriors Orochi 3'', they also tossed in {{Guest Fighter}}s NinjaGaiden's Ryu Hayabusa, and the TrojanWar's [[WarriorsLegendsOfTroy Achilles]].
* AlienVsPredator
* VideoGame/CartoonNetworkPunchTimeExplosion and its updated sequel basically answers the question, what would happen if WesternAnimation/{{Ben 10}} and WesternAnimation/SamuraiJack met in a dark alley, [[WesternAnimation/CodenameKidsNextDoor Father]] and [[WesternAnimation/SamuraiJack Aku]] had a little fiery feud, [[WesternAnimation/ThePowerpuffGirls Blossom]] and [[WesternAnimation/DextersLaboratory Dexter]] teamed up to fight Vilgax and [[WesternAnimation/TheGrimAdventuresOfBillyAndMandy Grim]] in [[WesternAnimation/TheMarvelousMisadventuresOfFlapjack Stormalong Harbor]]. The game answers these questions, and more.
* A mod for ''VideoGame/{{Doom}}'' Source ports, ''Samsara'' allow you to play as VideoGame/{{Doom}}guy, [[VideoGame/ChexQuest Chex Warrior]], [[VideoGame/{{Heretic}} Corvus]], [[VideoGame/Wolfenstein3D B.J. Blazkowicz]], [[VideoGame/{{Hexen}} Parias]], VideoGame/{{Duke|Nukem3D}}, [[VideoGame/{{Marathon}} Security Officer]], and [[VideoGame/{{Quake}} Ranger]]. And in any game outside their own, their characters even have respective IdiosyncraticDifficultyLevels depending on which one you chose. They're also balanced for class based gameplay in deathmatches, capture the flag, etc.
** VideoGame/{{Doom}}guy: Damage
** [[VideoGame/ChexQuest Chex Warrior]]: Defense
** [[VideoGame/{{Heretic}} Corvus]]: Utility
** [[VideoGame/Wolfenstein3D B.J. Blazkowicz]]: Marksman
** [[VideoGame/{{Hexen}} Parias]]: Brawler
** VideoGame/{{Duke|Nukem3D}}: Crowd Control
** [[VideoGame/{{Marathon}} Security Officer]]: Suppression
** [[VideoGame/{{Quake}} Ranger]]: Artillery
* ''VideoGame/MortalKombatVsDCUniverse'': The final epic battle ends in a draw with only Superman and Raiden left standing, but the storyline does feature DC characters winning more fights than MK characters, due to their side of the story being a chapter longer. Perhaps most notable is a scene where a ''weakened'' Captain Marvel is able to defeat Scorpion, Baraka, and Shang Tsung in quick succession.
* ''VideoGame/SuperSmashBros'' is the Nintendo example of this trope. It pits the Nintendo characters against each other outside their respective worlds. The final boss is the Master Hand to represent this is the characters in toy form fighting in the child's imagination.
* ''SoulCalibur'' 3, 4, and 5 all have the Create-A-Soul mode, which lets you build completely original characters. The games provide armor and equipment that lets you create characters from pretty much any franchise (within reason) and pit them against each other to see who's best. Some characters can be recreated with a striking degree of accuracy. You want one of [[Series/DoctorWho the Doctors?]] You can do it. Franchise/{{Batman}}? Harley Quinn? SelfDemonstrating/TheJoker? No problem. [[WesternAnimation/{{Futurama}} Zoidberg?]] WHY NOT ZOIDBERG? [[Wrestling/{{WWE}} The Undertaker?]] Absolutely. [[VideoGame/StreetFighterXTekken Bad Box-Art Mega Man?]] Paunchy stomach included. [[VisualNovel/AceAttorney Phoenix Wright?]] No objections here. Want to make the PowerRangers? Just pick a color. [[ComicBook/XMen Cyclops? Jean Grey?]] Other mutants too. [[VideoGame/{{Pokemon}} Pikachu?]] I CHOOSE YOU! TheMissingNo? Somehow... yes. DoctorDoom? Heck yeah! Film/AustinPowers? YEAH, BABY! ChuckNorris? Do you even need to ask? [[WesternAnimation/AdventureTime Finn, Jake, and Princess Bubblegum?]] MATHEMATICAL! [[Series/MythBusters Jamie Hyneman?]] Myth Busted. [[Franchise/StarWars Queen Amidala?]] The Force is strong with this one. [[Anime/GhostInTheShellStandAloneComplex Motoko Kusanagi?]] 5 lets you recreate her right from the moment you first pop in the game. The characters are nearly endless, and all yours to pit against each other as you wish. [[http://fuckyeahsoulcaliburcreations.tumblr.com/ Just check out this Tumbler for hundreds of recreations from 5 alone.]]
* ''VideoGame/AsurasWrath'': Lost Episodes 1 and 2 pits Asura against ''VideoGame/StreetFighterIV'''s Ryu[=/=]Evil Ryu and Akuma[=/=]Oni. The latter had to be buffed up to Asura's level to stand a chance, of course.
* ''VideoGame/QuakeIIIArena'': pits ''VideoGame/{{Doom}}'', ''VideoGame/{{Quake}}'', ''VideoGame/QuakeII'', ''VideoGame/Wolfenstein3D'' and OriginalGeneration characters against each other in a fight for supremacy.
* ''Sherlock Holmes versus Arsène Lupin'': The Frogware 2007 game, known in some countries as ''Sherlock Holmes: Nemesis''.
* The ''WesternAnimation/FamilyGuy vs. WesternAnimation/AmericanDad'' web fighting game in promotion of the series' DVD releases; [[StreetFighter Ryu]] is the game's boss.
* VisualNovel/FateStayNight: Revolves around KingArthur, [[Literature/TheEpicOfGilgamesh Gilgamesh]], [[ClassicalMythology Hercules]], Theatre/{{Medea}}, {{Medusa}}, [[CelticMythology Cu Chulainn]], [[MiyamotoMusashi Sasaki Kojirou]], TheHashshashin and [[{{Zoroastrianism}} Angra Mainyu]] being summoned into modern day for a fight to death.
** LightNovel/FateZero: Follows KingArthur, [[Literature/TheEpicOfGilgamesh Gilgamesh]], [[KingArthur Lancelot]], [[CelticMythology Diarmuid Ua Duibhne]], AlexanderTheGreat, [[JoanOfArc Gilles de Rais]], TheHashshashin and [[{{Zoroastrianism}} Angra Mainyu]] in a similar war.
** VideoGame/FateExtra: Changes it to [[TheRomanEmpire Nero]], [[JapaneseMythology Tamamo-no-Mae]], [[CelticMythology Cu Chulainn]], [[RomanceoftheThreeKingdoms Lu Bu Feng Xian]], [[TheVirginQueen Francis Drake]], [[KingArthur Gawain]], RobinHood, [[DynastiesFromShangToQing Li Shu Wen]], [[Literature/AliceInWonderland Alice]], [[{{Dracula}} Vlad III]] and [[UsefulNotes/{{Buddhism}} Vairocana]], along with the creators' own [[VisualNovel/{{Tsukihime}} Arcueid Brunestud]] and [[LightNovel/KaraNoKyoukai Shiki Ryougi]].
** Anime/FatePrototype: Had KingArthur, [[Literature/TheEpicOfGilgamesh Gilgamesh]], [[ClassicalMythology Perseus]], [[CelticMythology Cu Chulainn]] and [[Literature/BookOfRevelation The Beast]] in a fight to the death instead.
* In the ''VideoGame/HalfLife1'' mod ''The Specialists'', most character models are from some action movie (and two from video games): Smith Agents and Morpheus, from The Matrix; Castor, from Face/Off; Agent 47, from the Hitman series; and Gordon Freeman wearing a black trench coat. This means that it is impossible to play the game without an epic battle between action icons, unless everyone is using the generic Mercenary and Seal skins.
* ''VideoGame/ProjectXZone'' gives us [[TalesOfVesperia Yuri (with Estelle)]], considered as the biggest badass protagonist of the TalesSeries versus [[VideoGame/SuperRobotWarsOriginalGeneration Sanger]], Banpresto's biggest walking badass for one fight.
** This game also gives us [[DevilMayCry Dante]] (with Demitri), versus [[VideoGame/{{Darkstalkers}} Jeddah]], a fight we wanted to see back in VideoGame/CapcomFightingEvolution.
* ''VideoGame/SuperRobotWarsZ'' has one battle where half of the cast filled with famous HumongousMecha anime fight with another half the cast filled with famous HumongousMecha anime. Who wins? The side you control has to win, so you can progress through the game.
* ''VideoGame/PlayStationAllStarsBattleRoyale'': [[ExactlyWhatItSaysOnTheTin it's right there in the title.]]
* In-universe example in ''VideoGame/BrothersInArms: Road to Hill 30'': [[ThoseTwoGuys Allen and Garnett]] start two missions by having an argument regarding who would win a fight between Batman and Superman.
[[/folder]]

[[folder:Traditional Games]]
* ''Anachronism'': A card game that lets you pit various historical (or somewhat historical, like RobinHood) characters against each other. For more fun, trade the character's goodies around -- give Achilles Beowulf's chain mail and Miyamoto's katana.
* ''Who Would Win?'': ExactlyWhatItSaysOnTheTin. Two players each get a random character, and then an event. Argue why your character would win. Santa Claus vs. Genghis Khan in synchronized swimming? Babar vs. Einstein in ping pong?
[[/folder]]

[[folder:Web Original]]
* ''TheAnnoyingOrange'': In one episode, Liam the Leprechaun forces the orange to see if he was more annoying than {{Fred}}. It appears to end in a stalemate, only for Fred to get the last laugh.
* ''WillItBlend'': Anything, at all, versus a Blend-Tec blender.
* The now-defunct [[http://www.grudge-match.com/ WWWF Grudge Match]] though the archives are still there, listing the more than 200 fights the site has run.
* [[http://www.electricferret.com/fights/ The Comic Book Universe Battles]], which started in 1997 as a sub-section of a ''Series/XenaWarriorPrincess'' fan's Callisto fansite and eventually grew into something all its own. Seen as a friendly rival by the above Grudge match it later stopped proposing scenarios [[http://www.electricferret.com/cbub/ and let users submit, debate and vote on them]]. Currently user voting is down indefinitely but some of the scores are still in the database.
** In the late 2000's (around 2008 or 2009) the site was revamped to include 2 vs. 2 and 3-way battles as well as reintroducing the ability to submit characters to the database, however unfortunately at the end of 2013, the site's creator and owner stated that the CBUB (and its sister site the Fantasy Powers League) would be shutting down permanently.
* ''TheSpoonyExperiment'': had ''[[http://spoonyexperiment.com/2010/12/05/the-deadliest-character/ Deadliest Character]]'', a direct take-off of the aforementioned ''DeadliestWarrior'', featuring the [[PowerRangers Megazord]] vs. [[Franchise/{{Godzilla}} MechaGodzilla]]. [[spoiler:Megazord wins by summoning TheSixthRanger and tearing [=MechaGodzilla=] apart]].
** The [[WhatMightHaveBeen uncreated]] second episode promised a showdown between [[Series/DoctorWho Dalek]] and [[Franchise/StarTrek Borg]].
* WebVideo/TGWTGYearOneBrawl brought together dozens of gamers and reviewers from Website/ThatGuyWithTheGlasses for an epic throwndown. The winner: [[spoiler: It's a huge draw as a truce is declared when they raelize that they are all on the same team at the end of the day.]]
* ''Webcomic/TalesFromThePit'' exposes "Who Would Win" as a favorite conversational topic of the ''MagicTheGathering'' R&D team. Pairings include Franchise/{{Robocop}} vs. The Franchise/{{Terminator}} and Franchise/MyLittlePony vs. the Franchise/{{Transformers}}.
* [[http://screamsheet.wordpress.com/fights/ The Screamsheet]] has done weekly fights between a variety of characters since 2000. The fights have a loose continuity and several running jokes, such as Superman always losing and the Earth being destroyed multiple times.
* ''Webcomic/EightBitTheater'''s FourthWallMailSlot Twinkin' Out With Red Mage] ran several columns dedicated to Red Mage answering "who would win" fights suggested by readers, starting Twinkin' Out 7: Superfight Spectacular. Reader suggestions ran the gambit anywhere from comic book heroes and villains to real life celebrities and historical figures, including Lincoln versus John Wilkes Booth and Gandhi versus Martin Luther King Jr. The feature concluded its 2004 run with a Superfight elimination tournament that pitted Wolverine against Link (the latter of which had just defeated a three-man team of Pyro, Superman, and God to reach the finals) in the final match which remains unconcluded five years later.
** And don't forget the Flash animations featuring matchups between the webcomic's characters (removed from the official website, but still available [[http://www.newgrounds.com/portal/search/author/Meddros here]].
** Also, once the comic spent [[http://www.nuklearpower.com/2003/10/16/episode-342-hypothetically-speaking/ two]] [[http://www.nuklearpower.com/2003/10/18/episode-343-check-mate/ installments]] with RM and Black Mage discussing on who'd win, Franchise/{{Batman}} or DoctorDoom, with BM finishing the argument with "Doom's machinations are such that even if Batman wins, [[XanatosGambit his victory will somehow further Doom's schemes]]". [[http://www.nuklearpower.com/2005/08/27/episode-591-hypothetically-speaking-again/ Another]] had the two discussing on Bullseye vs. Green Arrow, with BM arguing against [[ImprobableAimingSkills precisely shooting several arrows at once]] -- until he [[TwangHello received it]] himself.
* [[http://thelonelywinds.com/phpBB2/index.php The Lonely Winds forum]] has three sub-forums dedicated to various [=USoUDs=] in eight different leagues of various power level and compositions.
* ''Numerous'' websites dedicated solely to what faction from ''Franchise/StarWars'' and ''Franchise/StarTrek'' would lay the ultimate smackdown upon all the others. Website/StarDestroyerDotNet is a particularly (in)famous one, and Website/{{Spacebattles}}.com caters to all kinds of sci-fi matchups but is invariably dominated by ''Trek'' vs. ''Wars'' as well as the occasional just-for-fun curbstomp (the Orcs from ''Literature/TheLordOfTheRings'' vs. modern machine guns, [[SuperiorFirepower carpet bombing from B-52s]], ''an orbiting Imperial Star Destroyer'', and finally, the real kicker, [[TabletopGame/{{Warhammer 40000}} doze udda Orkz]]). Both of these websites more or less grew out of the Usenet newsgroup alt.startrek.vs.starwars.
* "Dream Tournament", a popular series of vote-driven fanfics on the Usenet group rec.games.video.arcade from the mid-'90s, pitted FightingGame characters from different games against each other. The Tournament gave rise to several spinoffs, as well as many {{Fanon}} personality traits for the characters.
** There was an old fanfiction Dream Tournament called the ''FanFic/UltimateVideoRumble'', where some truly memorable fights happened both within and without the arena. Highlights include Haohmaru and Genjuro of ''SamuraiShodown'' fame clashing swords furiously, while everyone who attempts to break their battle gets tossed aside, and dysfunctional organizers and security staff who make Eddy Gordo of ''VideoGame/{{Tekken}}'' fame suffer after he got eliminated from the ring.
*** The UVR was a deliberate spiritual successor to the first three Dream Tournaments, continuing many of the fanon events and characterizations from the DT.
* Stefan "Twoflower" Gagne organized a RoundRobin tournament featuring characters from all over anime (and sometimes, beyond) called [[http://www.mtcffultra.com/ Magical Troubleshooting Crossover Fighting Federation ULTRA.]] The various writers used and abused pretty much the entire ProfessionalWrestling trope list, with backstage plots ranging from mere personal power grabs and MindControl to [[Anime/NeonGenesisEvangelion Third Impact]] and wresting Godhood from [[RanmaOneHalf Kasumi Tendo]] Herself.
** The golden rule staving off the inevitable FanBoy [[FlameWar flame wars]] was understood to read, "Anyone, under the right circumstances, can defeat anyone else in a fight." The only systemic exceptions to this idea were made to account for anime-style "weight restrictions."
** It's worth noting that the story of ''how'' Kasumi became God and several other plot points such as Dark Sakura originated from MTCFF '''Beta''' which was a single-elimination tournament decided by votes rather than by individual authors, with such oddities as [[FusionDance Fusion character]] "Nario" resulting from Naru of ''VideoGame/BattleArenaToshinden'' and Mario of ''Franchise/SuperMarioBrothers'' tying in votes.
* "Hitler continued laughing, then finally said 'Goku! You came here expecting to find a madman, but instead, you found a GOD!' Hitler had become a Super Saiyan." How's that for a CrackFic-style showdown? See it [[http://smallcave.net/goferchan/afgoku01.html right]] [[http://smallcave.net/goferchan/afgoku02.html here]] in all its Not Safe For Sanity glory. By the way, it also [[{{shipping}} ships]] Goku x Anne Frank.
* Ultimate Showdown tournaments are a [[http://board8.wikia.com/wiki/Most_Powerful_Character_Contest common occurrence]] on Website/GameFAQs' "Board 8", allowing users to debate to the most extremely geekish limits possible about who'd win. The arguing can lead to some, hmmmm, very curious victories (Apparently, Film/TheMask can just barely beat [[Anime/DragonBallZ Broly]] with cartoon physics, the most powerful ''VideoGame/{{Darkstalkers}}'' can win left and right merely based on their '''vague backstories''' alone, Voldemort can upset [[LyricalNanoha Nanoha's]] constant nuking of areas and people and [[Series/DoctorWho the Doctor]] can defeat ComicBook/TheFlash with, uhhh, timey wimey stuff. Or prep time. Or whatever).
* History nerds are somewhat fond of debating Alexander the Great vs GenghisKhan. This battle actually happens in ArthurCClarke and Stephen Baxter's collabaorative novel, ''Time's Eye''.
* [[http://www.rpgdl.com/ The RPG Duelling League]] is a site dedicating to deciding which VideoGame RPG characters would win in a fight. The site is organized into 6 week long elimination tournaments (refered to as seasons) with four different CharacterTiers (Light, Middle, Heavy, and Godlike). The voters who decide who wins are also ''strongly'' encouraged '''NOT''' to vote according to [[PopularityPower popularity]] or [[GameplayAndStorySegregation plot powers]], but rather comparative in-battle capabilities and performance.
* Whosthebitch.com was the HQ for a fun and easy game; simply match any two given personalities (or even inanimate objects) and answer the question, "Who's the bitch?" Basically pick which one would be the 'bottom' in a relationship between the two, and justify your answer with an explanation.
* [[http://www.youtube.com/watch?v=ryH1TB4gEUY Dead Fantasy]] shows what happens when a bunch of girls from the ''FinalFantasy'' series go up against a bunch of girls from the VideoGame/DeadOrAlive series. [[spoiler:In case you didn't figure it out by yourself, it's {{fanservice}}.]]
* Sites like Comic Book Resources and Hero Chat have their own (Comic Book Rumbles and It's Clobberin' Time!, respectively), among many, many other websites. They often [[FlameWar don't like each other.]] Most infamous incident was a flame war and board raid between Rumbles and Star Destroyer, after Rumbles determined Borg Cubes can destroy the Death Star. Cue FanWank and board raid.
* The Galactic Watercooler podcast has a recurring feature called [=Fantasy Sci-Fi League=] in which participants choose teams based on specific roles (warrior, pilot, reconnoissance, etc) and place them in a scenario such as the rescue of one of the podcasters from a [[Franchise/StarTrek Klingon]] prison planet, and give them some basic equipment (such as Carl Sagan's [=Starship of the Imagination=]). The winner is chosen based on the most entertaining way of completing a mission.
* ''WebVideo/EpicRapBattlesOfHistory'' does this, but with rapping.
* ''Blog/TheBraveAndTheBoldTheLostIssues'' often sets Franchise/{{Batman}} or [[ComicBook/FantasticFour The Thing]] against various characters.
* [[http://www.factpile.com/ Factpile]] mostly runs on this trope. It has branched out to include other topics, but is still mostly battles between fictional characters. It has also determined the outcome of the page image [[spoiler: Superman easily wins.]]
* MakeYourMove: applies this to VideoGame/SuperSmashBros with movesets for everything from King K. Rool to Socrates.
* ScrewAttack's ''WebAnimation/DeathBattle'': sets characters up against each other as well, from [[StarWars Boba Fett]] vs. [[{{Metroid}} Samus Aran]] to [[FinalFight Mike Haggar]] vs. [[StreetFighter Zangief]] to [[{{Transformers}} Starscream]] vs. [[WesternAnimation/MyLittlePonyFriendshipIsMagic Rainbow Dash]]. Notably not decided by votes, but by a look at each side's actual capabilities and extrapolating based on that.
** And they've done one for [[Anime/DragonBallZ Goku]] and {{Superman}}. [[spoiler:Superman won.]]
* Dark Horse Comics asked who would win; [[Webcomic/TheAdventuresOfDrMcNinja Dr McNinja]], or [[VideoGame/TeamFortress2 Saxton Hale]]? At the time of this edit, votes are [[http://www.darkhorse.com/Blog/686/dark-horse-vs-dr-mcninja-vs-saxton-hale still being accepted]]. Each character asked fans to vote for them on their [[http://drmcninja.com/ respective]] [[http://www.teamfortress.com/ websites]].
** Votes are already done. Winner: [[spoiler:Saxton Hale.]]
* DeadliestFictionWiki: using the formula from Deadliest Warrior, but for warriors of any media and franchise, with the warriors chosen by logical debates from the members of the site. It's essentially TheWikiRule for UltimateShowdownOfUltimateDestiny.
* Tor.com: Tor Books' website holds yearly "cage matches" pitting various fantasy characters against each other in a single-elimination tournament, with the characters' creators invited to write how ''they'' think each of their characters' battles would go.
* [[http://www.youtube.com/watch?v=yMgnNI0Puxo "Valve World"]], showing ''VideoGame/TeamFortress2'' Then ''VideoGame/CounterStrike'', ''VideoGame/{{Dota 2}}'', ''VideoGame/Left4Dead 1 and [[VideoGame/Left4Dead2 2]]'', ''VideoGame/HalfLife2'', ''Deathmatch Classic'', ''Day Of Defeat'', ''VideoGame/AlienSwarm'', ''VideoGame/{{Portal}}'' and then ending on ''VideoGame/HalfLife1''.
* TheOutskirtsBattledome exists for people to speculate who would win in a fight between two fictional characters or real-world people.
* ''The Alterverse War'':Kristofer Straub, the author of ''StarslipCrisis'', put togheter ''[[StarslipCrisis Fuseli]]'' vs. the ''[[Webcomic/SchlockMercenary Touch and Go]]'' [[spoiler:the ''Fuseli'' won, but only due to some clever maneuvering]].
* ''WebVideo/VideoGameChampionshipWrestling'' is an ongoing web series that uses recreations of both famous and relatively obscure video game characters (as well as some from non-game-based franchises and even a few people from real life) in the ever-glitchy VideoGame/WWEVideoGames in AI versus AI matches. It maintains a regular roster of wrestlers, so rematches where a previous winner lost and a previous loser won have happened before, such as [[VideoGame/BarkleyShutUpAndJamGaiden Charles Barkley]] versus [[Franchise/DragonBall Vegeta, and Nappa]] versus [[Creator/ValveSoftware Gabe Newell]].

* MTV's ''WesternAnimation/CelebrityDeathmatch'' is a {{claymation}} version of ExactlyWhatItSaysOnTheTin. Matches have included [[TheXFiles David Duchovny and Gillian Anderson]] vs. [[Film/MenInBlack Tommy Lee Jones and Will Smith]]; Bono vs. Fabio vs. Yoko Ono; Bette Midler vs. Cher; and [[Franchise/{{Batman}} Adam West vs. Christian Bale]].

* ''WesternAnimation/AdventureTime'': A college for worms has a "Theoretical fightonomics" class. According to the professor, the winner is always "Werewolf Queen".
** Invoked and Deconstructed in "Frost & Fire" where Finn tries to get Flame Princess to fight the Ice King in a Fire vs Ice themed battle. [[spoiler: It ends ''catastrophically'' with the Ice Kingdom getting razed, The Ice King almost getting killed, and Flame Princess breaking up with Finn when she learns of the details, because he hurt her. [[NiceJobBreakingItHero You blew it, Finn.]]]]

* [[http://www.artleo.com/images/201108/artleo.com_7634.jpg This image]], called ''War of the Worlds'' (Война миров), painted by the Russian contemporary artist Nikolai Kopeikin depicts an epic but gruesome battle between cartoon characters of mostly Western Animation and [[EasternAnimation Russian Animation]]. Not only this picture is an example of the trope but it also stresses the [[FandomRivalry rivalry]] between domestic and foreign animation in Russia.
* Don Bradman and Babe Ruth, widely recognised as the greatest ever players in cricket and baseball, respectively, met each other in 1932. While they didn't play against each other, certainly not in any formal capacity, Bradman offered Ruth the chance to try his hand at cricket. Ruth started by trying to bat cricket-style, and struggling to lay bat on ball, before switching to his baseball stance and hitting the Australian bowlers around the park. Ruth also took Bradman to watch a Yankees game, where Bradman surprised his host by spotting a double-play.
* Yalta, 1942. [[WinstonChurchill Winston "Brandy for Breakfast" Churchill]] and [[JosefStalin Josef "Steel Liver" Stalin]] have what is, in effect, [[http://www.bbc.co.uk/news/uk-22623251 a drinking contest]]. They go at it until three o'clock in the morning, but by one o'clock Churchill, suffering a "slight headache", has switched to wine. At which point Stalin presumably called him a pussy, fist-bumped Molotov, and cracked another bottle of vodka.
* The FinalBattle of ''Roleplay/DinoAttackRPG'' gives us Dino Attack Team, Alpha Team, Agents, Ogel Drones, Chinese soldiers, Rogue Knights, and Brickster-Bots battling the Maelstrom, Mutant Dinos, Inferno agents, and Fright Knights, with XERRD [[HeelFaceTurn switching sides midway through]].
** Even one specific fight within that battle can qualify for this trope: [[{{Cyborg}} Cyri]][[{{Mutant}} sta's B]][[TyrannosaurusRex ane]] versus [[MadScientist Dr. Inferno's]] [[HumongousMecha Robot Mech]].
