->''"There are forces in the multiverse far beyond anything you've ever dealt with. Ancient, mindless evils that fill in the cracks and eat dimensions just for a snack. Monstrous deities and empires spanning Universe after Universe have risen and fallen in the span of forever! But there is still one individual, one being that they are all horrified of! When I saw him coming near my universe, I fled. Muhahahhahahha. Weep for your Universe, Linkara! Weep for all Universes! For Lord Vyce is coming! Hihihi. And all that he sees, he conquers! HAHAHAHHAHAHAHAHAHA!"''
-->-- '''Doctor Linksano''', ''WebVideo/AtopTheFourthWall'', ''ComicBook/TandyComputerWhizKids: Fit To Win Review''

Sometimes an EvilOverlord, GalacticConqueror, DimensionLord, [[DemonLordsAndArchdevils demon lord, archdevil]], {{Physical|God}} GodOfEvil or EldritchAbomination decides there's only one evil goal big enough that suits him - bring TheMultiverse to its knees. Not only our Earth, but every dimension, every alternate reality, every single planet and life form in the whole multiverse. He may want to conquer it. Or he might want to destroy it. In both cases [[AuthorityEqualsAssKicking he's the]] [[SlidingScaleOfVillainThreat ultimate threat]], more powerful than anyone else our heroes has ever met. He can destroy planets, blow up entire cities with one finger, erase whole dimensions. To [[TheWorfEffect show how strong he is]], he can even kill the GuardianOfTheMultiverse, the very first person that will oppose him. And when he says AGodAmI, he's being modest. Fighting with him is usually our hero's greatest task ever. To defeat him there's usually a gathering of the greatest army of heroes that multiverse has ever seen. If he comes back after being defeated he will most likely be a [[VillainDecay shadow of his old self]].

Is often used as an OriginalGeneration villain or a LegionOfDoom for a IntercontinuityCrossover.

Compare with OmnicidalManiac.

This is one of the two highest-ranking AuthorityTropes, the other being GuardianOfTheMultiverse. The next rank down is DimensionLord.

Note: Technically, the Universe means everything in existence, so if two "universes" have any connection, they are one universe. "Dimension" would be more accurate for a parallel "universe", but this is one of those comic book things you have to let slide. (Although some modern physical cosmological models, such as M-Theory, are beginning to dispense with the classical definition of a universe as "everything" and are now more adapting to the definition of "''one'' everything". ScienceMarchesOn.)



[[folder:Anime & Manga]]
* Several characters in the ''Franchise/{{Digimon}}'' series:
** ''Every'' BigBad who isn't a DiscOneFinalBoss decides that conquering the Digital World isn't enough - they also want the Real World as well.
** ''Anime/DigimonTamers'': The D-Reaper attempted to delete Earth in accordance with its purpose once it was accidentally brought over into it.
** The real king of this trope is Millenniumon who, as revealed in the ''VideoGame/DigimonWonderSwanSeries'', eventually aspired to conquer all alternate-reality Digital Worlds (that is to say, effectively the alternate worlds of every ''Digimon'' canon ever). He comes dangerously close to succeeding, being particularly successful in being TheManBehindTheMan as far as almost every bad thing in the ''Anime/DigimonAdventure'' canon is concerned.
** ''Anime/DigimonXrosWars'': Baguramon is probably the closest in the franchise to rival Millenimumon in this aspect, and is probably second in power to Milleniumon as well.
** The exact nature and source of The Infection of The Digital World in ''Anime/DigimonAdventureTri'' isn't yet known, but the resident GuardianOfTheMultiverse revealed that it poses a threat to all realities; Real, Digital, and everything else Unknown.
%%* [[spoiler: Byakuran]] of ''Manga/KatekyoHitmanReborn''.
* The titular character of ''{{Anime/Noein}}'' who snapped after looking through countless universes to find one that didn't end in tragedy. After failing to do so he decided it would be better to tear down the multiverse and return everything to the void.
%%* Yubel in ''Anime/YuGiOhGX''.
%%* Likewise, the Professor [[spoiler: aka Leo Akaba, founder of Leo Corporation and Reiji's father.]] He's already taken over [[spoiler: Fusion Dimension]], and has his sights set on [[spoiler: both Xyz Dimension (which has been putting up a fight for some time now), and Standard Dimension.]]

[[folder:Comic Books]]
* The Anti-Monitor from Creator/DCComics ''ComicBook/CrisisOnInfiniteEarths''. {{Superman}}'s EvilCounterpart Superboy Prime from its sequel, ''ComicBook/InfiniteCrisis''. And Mandrakk the Dark Monitor from ''ComicBook/FinalCrisis''. Yes, DC loves this trope.
** Infamous ''ComicBook/CountdownToFinalCrisis'' gave us Monarch, who gathered an army of supervillains from the whole multiverse to fight its protectors, the Monitors. At the same time one of the Monitors, Solomon, plotted with Darkseid to conquer the multiverse. It's hard to say which one was worse.
** Monarch was actually introduced much earlier in the (not very well-received) CrisisCrossover ''Armageddon 2001'', but he had nothing to do with the Multiverse (or the current Monarch, either).
** {{ComicBook/Darkseid}}, while normally a GalacticConqueror, ascends to a MultiversalConqueror in ''ComicBook/FinalCrisis'', and stays there into the ComicBook/{{New 52}} reboot, where we see him sending up multiple fronts of an invasion force to attempt to conquer several Earths within the Multiverse simultaneously.
* ''Comicbook/{{Exiles}}'' enemy Hyperion was a member of another team sent to repair alternate realities who killed everything in his world and become both a DimensionLord and completely alone. However, instead of helping alternate realities he tried to conquer them.
* In a ComicBook/FantasticFour storyline, the Marquis of Death traveled through Alternate Earths, destroying them, killing everything, or any sort of villainy he felt like. All [[ForTheEvulz for fun]].
* The ''ComicBook/MarvelZombies'', after their ZombieApocalypse conquered their own universe, started looking for a way to spread it across the whole multiverse, and tried to attack both the MarvelUniverse and the UltimateUniverse. It's hard to say if they are Multiversal Conquerors, or if it's TheVirus that controls them.
** [[spoiler: The "Marvel Zombies Return" mini subverted that: the zombies are struck between two Earths - when they conquer one, they end up being sent to the second's past in an endless circle.]]
* Another Marvel villain, Abraxas, wants to conquer the whole multiverse, but is kept in check by Galactus - as long as Galactus lives, Abraxas can't even exist. Also yet another Marvel villain, the Beyonder. Marvel loves this trope too.
** And then you have Hyperstorm, another Fantastic Four villain who's the future son of Franklin Richards and Rachel Summers. Let's drive this point home, shall we? ''Daddy can alter reality with his mind, and mommy is a cosmic-level telepath/telekinetic that can access the Phoenix Force.'' Obviously, their kid was tremendously powerful and conquered several universes in his adult life.
** Another Marvel villain who semi-fits this trope is Kang The Conqueror, time-traveling military genius who's conquered universes, not through raw power, but through tactics and strategy.
** Yet, another Marvel villain - Amatsu Mikaboshi, [[ComicBook/TheIncredibleHercules Chaos King]], who is a void that existed before creation of the first Universe and TheMultiverse and seeks to destroy it all, until nothing but him will remain.
** And another Marvel villain, or rather bunch of those - the [[EldritchAbomination Many-Angeled Ones]] of the Cancerverse, beings that killed Death and conquered their Universe, and wanted to do the same to other Universes, starting with main MarvelUniverse. [[Comicbook/DoctorStrange Shuma Gorath]] is probably the most well known, and is the ruler of over a hundred universes.
** Another one - Comicbook/DoctorStrange's ArchEnemy Dormammu, EldritchAbomination and GodEmperor of the [[EldritchLocation Dark Dimension.]]
*** Same applies to his sister, Umar, though fact she is second to him in power tends to limit her a bit.
* ''ComicBook/TwoThousandAD'':
** ''ComicBook/{{Shakara}}'': Subverted. The Overlord orders the construction of the Infinity Engine, a galaxy-sized device that he claims will allow The Hierarchy to conquer other universes. In fact, he means to use it to [[OmnicidalManiac destroy all of reality]].
** ''ComicBook/JudgeDredd'': The Dark Judges are an unconventional example, given that their real objective is to wipe out all life across the multiverse, but given what we've seen of [[TheNecrocracy their decimated homeworld]], the result fits the spirit of the trope. Judge Death, for instance, stresses that his jurisdiction is "limitless".

[[folder:Fan Works]]
* Every BigBad in [[http://alaxr274.deviantart.com/gallery/37280372 Hottie 3: The Best Fan Fic in the World]] and it's sequels.
* ''Fanfic/TheConversionBureauTheOtherSideOfTheSpectrum'' has the MirrorUniverse EvilCounterpart of Princess Celestia, [[GodSaveUsFromTheQueen Queen Celestia]]. It's very clear once she's done with [[AssimilationPlot ponifying all of humanity]], Canon Equestria is next, and according to [[spoiler: Discord]], she'll only keep going...
--> [[spoiler: '''Discord''']]: "TheMultiverse is vast, each world having vastly varied ways of existing, all with different ideals. Something the corrupt queen wouldn't be able to stand. Oh, there are powers out there that can rival, yes, or even beat her. But she will play it smart; she will gather power from other worlds before finally striking, [[WeHaveReserves with a]] [[ZergRush limitless army]] at her beck and call from dozens, if not hundreds, of worlds."
* ''FanFic/JewelOfDarkness'': The [[GuardianOfTheMultiverse Endless Council]] fears that [[BiggerBad Trigon]] will become this if [[VillainProtagonist Midnight]] fails to fight off his influence and let him win. This is why they decide to [[ShootTheDog send an assassin after her]].
* Titan from ''Fanfic/MyBravePonyStarfleetMagic'', [[WordOfGod according to the author]].
* The ''FanFic/PonyPOVSeries'' has [[KnightTemplar Nightmare Mirror]] ([[spoiler: Applejack]]'s potential SuperpoweredEvilSide), who was planning on moving onto this after [[TheAssimilator absorbing all her alternate selves]]. Fortunately, this backfired on her when several alternate [[spoiler: Applejack]]s (including the primary series one) teamed up to use the Elements of Harmony and defeat her.
* Princess Jody in [[http://alaxr274.deviantart.com/gallery/33810717 Super Milestone Wars]], the Biggest Bad and King Dyce in [[http://alaxr274.deviantart.com/gallery/36864527 Super Milestone Wars 2]].
* ''Fanfic/TheEquestrianWindMage'': According to Grogar (when he's recruiting Tirek for the growing LegionOfDoom), [[GodOfEvil Majora]] isn't planning at stopping with the conquest of Hyrule and Equestria, or even their attached dimensions. He's planning on establishing himself as GodEmperor of ''all'' worlds.
* ''Fanfic/TheLastDaughter'', a crossover between ''Superman'' and ''Literature/{{Worm}}'' have the Destroyers, a race of parastic energy worms. They arent "conquerors" in the traditional sense, but function more as a hive-mind. They grant superpowers to a species, then absorb all useful knowledge before destroying that particular species from every possible version of itself throughout the multiverse. Krypton was one of the few that was spared because alternate Kryptons are extremely rare and was thus useless for the Destroyers experiments.

[[folder:Films -- Live-Action]]
* Ultraman Belial in ''Film/UltramanZeroTheRevengeOfBelial''
* The rulers of Outworld from the 1995 ''Film/MortalKombat'' movie have to win 10 consecutive MK tournaments in order to conquer the realm of Earth. So far they've won 9.
* Yulaw, from ''Film/TheOne'' (2001). His ultimate goal is to kill all 124 alternate versions of himself from parallel universes to absorb their life force believing he'll become an invincible, [[AGodAmI god-like]] entity.
* Gozer the Traveler from ''Film/Ghostbusters1984'' will conquer your dimension and to be a sport he/she'll adopt any form you choose first.

* The White Witch Jadis in ''Literature/TheChroniclesOfNarnia'' is a downplayed example. She starts out as an empress of Charn (which she ultimately destroys to avoid being overthrown), then comically fails to conquer Earth, and finally plunges Narnia into a hundred-year ice age and rules with an iron fist. Jadis doesn't rule more than one universe at a time, but she probably would given the opportunity.
* In ''Literature/TheDeathGateCycle'', [[NeglectfulPrecursors the Sartan]] broke the world down into seven parallel dimensions - [[FloatingContinent Arianus]], [[HollowWorld Pryan]], [[LethalLavaLand Abarrach]], [[WaterIsAir Chelestra]], the Vortex, [[DeathWorld the Labyrinth]], and [[GhibliHills the Nexus]] - millennia ago. As of the present story, [[SorcerousOverlord Lord Xar]], ruler of the Sartan's rivals the Patryns, indends to conquer them all, and already controls the Nexus and parts of the Labyrinth.
* Metatron and his angels in ''Literature/HisDarkMaterials''. While they apparently do not want to rule physically, they do want to install their religious ideals everywhere. Considering the size of the angelic army in the final book compared to the sheer amount of universes with creatures in them to which the concept of "Religion" is propably very alien (the Mulefa), not to mention that several significant events (such as Jesus being born) may not even have happened in some of them, their prospects are propably not very good, although the books never bring that issue up. They get defeated nonetheless, by a - comparably - small opposing force consisting of locals of "only" a few universes and the final battle of the two armies, while fitted with grand and bombastic visual displays (such as the angelic cloud fortress) seems to be on a smaller scale than World War II and is certainly shorter - hardly worthy of a multiverse-deciding conflict.
* Arguably ''Franchise/TheHitchhikersGuideToTheGalaxy'''s [[AIIsACrapshoot Mark II]].
* In ''Literature/WitchesBrew'', Rydall of Marnhull claims to be one of these, planning to make Landover his next conquest. [[spoiler:Turns out he's actually a local nobleman, working with the titular witch to overthrow Ben]].
* The "Black Hats" from Creator/RobertAHeinlein's ''Literature/TheNumberOfTheBeast''. They don't openly rule, but they have agents on many worlds who assassinate anyone else trying to develop interdimensional travel.
** Also a bit of a subversion. [[LeaningOnTheFourthWall They exist because otherwise]] [[AnthropicPrinciple interdimensional travel would be less dramatic.]]
* Appears in ''Literature/SkulduggeryPleasant'' as an unintended consequence [[spoiler:of banishing the Faceless Ones. Although thousands of years ago they were thrown out of the main universe, it taught them the secret of dimensional travel, and for the past few millienia they have been jumping from universe to universe, devouring them entirely as they go...]]
* The empire of the Dark Tower in the ''[[Literature/{{Somewhither}} Tale of the Unwithering Realm]]'' has taken over nearly all of the alternate Earths in the multiverse, with only a handful (including our Earth) remaining.
* In the Tramorea saga, this is what the Dark God [[spoiler: actually a Sufficiently Advanced human]] Tubilok aims to do.
* Possibly Creator/HPLovecraft's Mi-Go. In "Literature/TheWhispererInDarkness" it's mentioned that the ones present on Yuggoth are but a small outpost of an impossibly ancient and powerful civilization that originates from outside our universe. It's implied that they conquered their own universe and possibly others, and are now invading ours.
** They don't seem ''that'' ambitious, at least on Earth, possibly because it's the reserved playground of Cthulhu et al. They're universally widespread, but don't seem interested in outright conquest unless it brings them extremely good payoff.
* The later ''Literature/StarCarrier'' novels introduce a race, whose technological level is far beyond even the [[TheEmpire Sh'daar Masters]]. This race (or a group of races) has an empire that spans several ''universes'' and their next target appears to be ours. The humans visit a distant future through a [[PortalNetwork TRGA cylinder]] and are shown the Milky Way sealed in a galaxy-wide DysonSphere.

[[folder:Live-Action TV]]
* Davros fills this role in the series 4 finale of ''Series/DoctorWho'', although he wants to [[OmnicidalManiac destroy them]] rather than rule them, leaving only Daleks.
** In the Eighth Doctor [[Magazine/DoctorWhoMagazine DWM]] comic ''The Glorious Dead'', [[spoiler:the Master seeks to remake the entire ''omniverse'' in his image.]]
* Gorm conquerer of a 1000 realms in ''Galidor: Defenders of the Outer Dimension''.
* The [[LegionOfDoom Dai-Shocker]] organization and its leader [[spoiler:Tsukasa Kadoya]] from ''Series/KamenRiderDecade''.
* The Kromaggs in ''Series/{{Sliders}}''.
** One episode has Maggie wake up at a military base and told that the people of this world were able to fight off the Kromaggs and captured their sliding technology. Several holographic displays behind the general leading the campaign show worlds in the process of being retaken from the Kromaggs. Maggie quickly spots inconsistencies, such as a one-star general leading a multi-universe military campaign. This turns out to be a LotusEaterMachine, apparently designed for healing purposes.
* ''Series/{{Supernatural}}'': The finale of Season 12 introduces Apocalypse World, a run-down wasteland ruled by the ArchangelMichael in the aftermath of the war between heaven and hell. He's planning on invading the main universe that the heroes live in, which he refers to as Paradise World, since he wants to "trade up".

[[folder:Tabletop Games]]
* The ''TabletopGame/{{Champions}}'' verse had Tyrannon, an immensely powerful dimensional lord who seeks to conquer all dimensions. His being manifests in 888 bodies at once, of varying levels of power; his primary or "true" form, which resembles a gigantic tree and cannot move, lives at the heart of Thulkos, his native dimension. When he conquers one dimension completely, he merges it with his home dimension and forces its inhabitants to worship him and commit sacrifice. Doing so increases his power and his hunger.
** The Fifth and Sixth editions of the setting added Istvatha V'han, Empress of a Billion Dimensions. She takes a more technological approach to dimensional conquest, as opposed to Tyrannon's mystic nature, and rather than merging dimensions, she consolidates her power through BreadAndCircuses.
* In ''TabletopGame/MagicTheGathering'', there's Elesh Norn, the Grand Cenobite. She has seen that Mirrodin will merely be the first plane to fall to the new Phyrexia.
** She inherited this from Yawgmoth, who built the ''old'' Phyrexia and set off to conquer every plane he didn't destroy. [[DystopiaJustifiesTheMeans For]] [[BodyHorror their]] [[AssimilationPlot own good]].
** Phyrexians aren't the only ones. Demon Ob Nixilis was conquering countless of planes ever since becoming a Planeswalker. This also seems to be the main goal of dragon Planeswalker Nicol Bolas.

[[folder:Video Games]]
* ''VideoGame/CityOfHeroes'' brings us the Rikti, who at first seem to be the classic AlienInvaders and are actually referred to as such throughout the [[{{Backstory}} First Rikti War]]. Turns out that they're actually mutated humans from a parallel Earth, who are going dimension-by-dimension and forcing the change one world at a time. It's implied that Primal Earth (the "main" world) was one of the first to successfully fight them off due to the presence of superheroes; they didn't fare much better on Praetorian Earth because about 95% of it is either blasted with nuclear fallout or overrun with the [[GaiasVengeance Devouring Earth]].
* ''VideoGame/DissidiaFinalFantasy'': Most ''Franchise/FinalFantasy'' [[BigBad Big Bads]] have nothing to do with this. [[VideoGame/FinalFantasyII Emperor Palamecia]] wants to rule the world. [[VideoGame/FinalFantasyIII Cloud of Darkness]] and [[VideoGame/FinalFantasyV Exdeath]] want to make everything fall into [[CessationOfExistence the Void]]. [[VideoGame/FinalFantasyVI Kefka]] wants to destroy everything ForTheEvulz. [[VideoGame/FinalFantasyVIII Ultimecia]] wants to conquer the structure of time and create a world where past, present and future are one. But thanks to [[VideoGame/FinalFantasyI Chaos]] who gathered them all, revealing that there's more than one Universe, they started to think at a completely new level. OhCrap indeed.
* In ''VideoGame/PokemonUltraSunAndUltraMoon'' you encounter an AlternateUniverse version of [[TheDon Giovanni]] who attempts to become this by gathering other [[BigBad evil team leaders]] and forming a LegionOfDoom in order to create an army of [[EldritchAbomination Ultra Beasts]].
* The Combine of ''VideoGame/HalfLife2'' and its episodes fit the bill as parallel-universe conquerors, having already taken over an unknown number of realities and adopting their lifeforms for use as highly-specialized weapons or slave labor, and stripping the realities of their resources until it's nothing more than a lethal rock. They're also capable of quick travel between these universes, but it's rather limited. The Xen and Race-X aliens (and arguably even humanity) of ''VideoGame/HalfLife1'' may be parallel-universe warmongers on a smaller scale. Notably (and uniquely), it's not clear that the Combine even possess the space flight technology necessary to conquer multiple worlds within any given universe; they may simply invade the same planet again and again, across an infinite number of parallel realities.
* Several of the ''VideoGame/KingdomHearts'' villains.
** This is actually what Xemnas becomes when he absorbs the titular MacGuffin in ''VideoGame/KingdomHeartsII'', given the multiversal nature of the Disney worlds in the series mythos.
* The rulers of Outworld from ''VideoGame/MortalKombat'' must win an MK tournament within a realm in order to conquer it. They've won every single time and the realm of Earth is next. Its heavily implied they are being subtly influenced by a entity known as [[GreaterScopeVillain the One Being]], whose corporeal body is revealed to be the many realms that were split by the Elder Gods and it seeks to reunite them and become whole once again. Most main villains' endings (which are non-canon) involve the One Being being reawakened after the realms were combined.
* [[OriginalGeneration 99]], the BigBad of ''VideoGame/NamcoXCapcom''. When player finally faces it, 99 is still missing half of [[VideoGame/SoulEdge its essence]] and instead use [[TheDragon Saya]] for replacement. Yet it still has enough power to merge four dimensions together and resurrect groups of {{Big Bad}}s to [[BossRush aid it]] upon its awakening. And this is just the beginning of its process to rule new - single - world.
* Tyrant Overlord Baal from the ''Creator/NipponIchi''-verse. Most high-level [[DimensionLord Overlords]] can and will conquer any netherworlds they'll get their hands on, but Baal is the most well-known, showing up as a BonusBoss is almost all of the Nippon Ichi games.
** Overlord Zenon from ''VideoGame/{{Disgaea 2|CursedMemories}}'' used to act this way in his youth, but seems to have settled down by the beginning of the game and is content with ruling only Veldime -- [[spoiler:or so everyone thinks up until it's revealed he's a fake and the real Overlord Zenon tries to go right back to destroying everything once released.]]
* YHVH, the Great Will, is implied to be this in ''VideoGame/ShinMegamiTenseiIIINocturne''. Untold billions of Earths rise and fall at his command only to rise again and over and over ad infinitum, all as part of a grand experiment to create a perfect society that will never question his rule.
* Count Bleck from ''VideoGame/SuperPaperMario''. He's only going to conquer part of it, and then use the power gained from that portion to destroy the entire multiverse so he can [[spoiler:not]] make a new one. [[spoiler: Dimentio also counts.]]
* Dark Brain from ''VideoGame/SuperRobotWars'' game series travels through alternate universes and destroy them. Subversion, since Dark Brain doesn't care much about conquering the universes as seeking the [[McGuffin 12 keys]].
* The Guardian from ''VideoGame/UltimaUnderworld II'' is capable of spanning multiple planes of reality at once and aims to conquer each one.
* [[BigBad Trillion]] from ''VideoGame/TrillionGodOfDestruction'' is explicitly stated to be from an entirely different dimension, although it's not so much a "conqueror of worlds" as a "devourer of worlds", with the Underworld being just being the most recent dimension on the menu [[spoiler:after the Human World, most of Heaven, Faust's dimension, and who knows how many others beforehand]].
* In ''VideoGame/TheWitcher3WildHunt'', the Wild Hunt are actually the military force of a faction of elves from another dimension called the Aen Elle. They regularly raid other dimensions for slaves, but their means are imperfect, limiting their numbers during said raids and making them appear as spectral wraiths. They seek to become this trope in full by obtaining the Child of the Elder Blood, the last descendant of a eugenics project of theirs, who would give them the power to transport the full might of their military to other worlds. Too bad for them that said Child of the Elder Blood is the adopted daughter of a certain badass Witcher.
* The Domain in ''VideoGame/FreedomForce'' and its leader Lord Dominion. In fact, the only reason he doesn't just crush Earth, the last remaining free world in TheMultiverse, is because he's bored with the easy conquests. His plan is to give the worst of the worst of humans the Domain's secret weapon - [[SuperSerum Energy X]]. He then plans to sit back and watch Earth tear itself apart. Luckily, an alien spy named Mentor overhears this and steals the ship carrying the canisters of Energy X. The Domain chases him and shoots him down over Earth, with the canisters spilling all over Patriot City, empowering both heroes and villains.

[[folder:Web Comics]]
* Smiling Man from ''Webcomic/TheCrossoverlord''.
* Evil Overlords United from ''Webcomic/CrossoverWars''.
* Lord English from Webcomic/{{Homestuck}}.
* Each of the [[SevenDeadlySins Seven Demiurges]] in ''Webcomic/KillSixBillionDemons'' rules over [[NumerologicalMotif a seventh of Creation's 777,777 worlds]] after the treaty following the Second Conquest was made.

[[folder:Web Original]]
* ''Literature/{{Defection}}'': One of the many dangers that seems to close in on the Marsh family.
* ''WebOriginal/ProtectorsOfThePlotContinuum'': The Sunflower Emperor, leader of the PPC's EvilCounterpart, the Enforcers of the Plot Continuum.
* In ''WebVideo/TheSpoonyExperiment'' and ''WebVideo/AtopTheFourthWall'', Alternate Doctor Insano was once trying to destroy entire Multiverse with [[http://thatguywiththeglasses.com/videolinks/bt/spoonyone/reviews/7238-warrior1 Warrior #1]] comics.
** It was recently revealed that [[spoiler: [[WebVideo/AtopTheFourthWall Mechakara]] was attempting this as well]].
** Ano now, as seen at page quote, Lord Vyce. [[spoiler: It's revealed by none other than Vyce himself that he only does this to protect the multiverse from something [[EldritchAbomination worse.]] And he takes out ''[[Franchise/SilentHill Pyramid Head]]'' with a single stab from his weapon, in between beating Linkara [[CurbStompBattle senseless]] with his bare hands.]]
*** Vyce may be a subversion: [[spoiler:In a later episode, Linkara says that he did some checking and discovered that Vyce would only conquer a couple of planets before moving on to the next parallel world. Vyce makes the point that conquering an universe would cost a lot of time and resources that he didn't have, but Linkara still uses it to mock him for not being as awesome as he claims to be.]]
*** Vyce also shares a history with 'The Smiling Man' mentioned above, since the villain appeared in the 'Lightbringer' webcomic which was also created by Lewis Lovehaug. As well as [[spoiler: A similiar punishment upon defeat. Since both are stranded on a world in another reality with no intelligent life and only basic supplies for survival.]]
* ''WebOriginal/{{Inglip}}'': The Dark Lord Inglip has, at the very least, footholds in [[http://i.imgur.com/zPrsO.gif over one hundred realities.]]

[[folder:Western Animation]]
* Towards the end of ''WesternAnimation/SpiderManTheAnimatedSeries'', a different universe Carnage-Spiderman goes psycho (more than usually Carnage goes) and tries to destroy all the Universes. It's up to a group of alternate-Peter-Parkers to stop him.
* ''WesternAnimation/TeenageMutantNinjaTurtles2003'': While the Shredder isn't nearly as powerful as the average MultiversalConqueror, he still decides to give it a go after discovering the multiverse in ''WesternAnimation/TurtlesForever''. Unfortunately for the multiverse, all he needs to do in order to destroy it is to [[spoiler:kill the turtles in "[[ComicBook/TeenageMutantNinjaTurtlesMirage Turtle Prime]]", the universe of the first issue of the original TMNT comic book. Unfortunately, that act would ''destroy'' the multiverse -- however, by the time the Shredder finds out, he doesn't care, having gone mad from the revelation that ''every'' single universe has a team of mutant turtles to thwart him and his plans, and goes through with it if it means he can ''finally'' win]].
* In ''Franchise/{{Transformers}}'', Unicron is a PlanetEater who wants to eat ''everything''. One planet at a time, one timeline at a time, one universal stream of branching timelines at a time, in sequence. When he says he wants to be completely alone, ''he damn well isn't beating around the bush''. Even if he's destroyed in any one universe, he just gets shunted to another to start over again thanks to mucking about with different flows of time across the multiverse. Oh, sure, there are a ''few'' permanent methods of dealing with him, like trapping him in a physical form to slow him down, [[Anime/TransformersCybertron but if they go horribly wrong, well...]]
** One Comic has another Multiversal constant state that he has so far consumed some 47% of the known Multiverse. Yeah. Not mucking about.
