->''"Time for a new start. Clean slate. A re-made universe. ''My'' universe. Who knows? Maybe one world... one universe-- won't be enough."''
-->--'''Hal Jordan''', ''ComicBook/ZeroHour''

A step above GalacticConqueror but below GuardianOfTheMultiverse and MultiversalConqueror, this villain rules an entire universe with an iron fist. Sometimes ''several'' universes. He's ready to add ours to the list, just as soon as those pesky heroes from Earth are out of the way...

Dimension Lords are usually demons or cosmically powerful mages, or have access to such a high level of AppliedPhlebotinum that their technology [[ClarkesThirdLaw might as well be magic]]. They may be gods or {{Eldritch Abomination}}s. Their universes may be seriously large, or may be pocket dimensions not much larger than, say, Earth. It's still fairly impressive. Despite their [[OffscreenVillainDarkMatter nigh-infinite]] real estate, [[WeHaveReserves minions]], and [[PhysicalGod personal power]], though, Dimension Lords [[TheGoodGuysAlwaysWin seldom have any more success with their evil plans than do lesser villains]]...

Note that unlike the EvilOverlord, the Dimension Lord is often the [[RoyalBlood legitimate ruler]] of his dimension.

If Dimension Lord gets too ambitious, he often becomes MultiversalConqueror.

Trope name by Dean Shomshak, author of the ''TabletopGame/{{Champions}}'' super-hero RPG sourcebook "The Ultimate Supermage."

[[CouncilOfAngels Councils Of Angels]] / CelestialParagonsAndArchangels, DemonLordsAndArchdevils and [[PhysicalGod physical gods]] are fairly often Dimensional Lords.

!!Examples

[[folder:Anime]]
* Emperor Muge Zorbados from ''Anime/{{Dancougar}}''.
* ''Franchise/SailorMoon''
** Queen Metaria (working through Queen Beryl) and behind Metaria is an even higher up entity named Chaos.
** If her name is anything to go by, the manga's Sailor Cosmos might be a benign version of this trope. In the BadFuture whence she hails, all of her allies, every Sailor Scout, and every life, [[PyrrhicVictory is long dead]], and she is the only one still left fighting Chaos, in its purest form. The name "Cosmos" refers to her role to defend the universe.
* The Anti-Spiral from ''Anime/TengenToppaGurrenLagann'', [[WellIntentionedExtremist who did so to prevent the destruction of the universe.]]
[[/folder]]

[[folder: Comic Books ]]
* Creator/MarvelComics has Dormammu, the immortal and unstoppable god-tyrant of the mystical "Dark Dimension", worshiped as a deity in thousands of other universes, something worse than a demon, older and far more powerful than any elder god, possessor of sufficient might to have defeated cosmic entities such as the Phoenix Force or Eternity in personal combat, able to rewrite entire universes, and creator of kings of hell of the highest order, with the ultimate goal of slaughtering any rival higher powers, assume control of all life and afterlife, and [[DystopiaJustifiesTheMeans turn both into an inescapable neverending torture camp from birth to death and anything beyond]]. Arch-enemy, and most dangerous foe of Comicbook/DoctorStrange, and the first classic Dimension Lord. Arguably the most genuinely terrifying absolutely evil recurring villain in the Marvel roster. Think Comicbook/{{Darkseid}} taken to a much higher scaled ultimate extreme. Some of his plots stretch billions of years before coming to fruition, but luckily he's usually extremely arrogant and not a particularly inventive schemer. Then again he doesn't need to be, as he is one of the most powerful known {{Eldritch Abomination}}s in existence. His twin sister Umar also fills this role. She is the more dangerous of the two, despite being less powerful, because she is intelligent and very patient -- fortunately she doesn't care about destroying our world as much as her brother does.
* Mephisto, lord of one of several Hells in the Franchise/MarvelUniverse.
** An interesting case is ComicBook/IllyanaRasputin[=/=]Magik, who is a Dimensional [[EvilOverlord Overlord]] and (usually) one of the good guys.
** While Meffy is the most commonly used one, we also have other demonic overlords: Satannish, Nightmare, Belasco, etc. etc. Occasionally they claim to be the [[{{Satan}}the same guy]].
** Daimon Hellstrom is also lord of a Hell Dimension and is all powerful when there. He spends more time on Earth, though, and is also usually one of the good guys.
* Trigon the Terrible, demonic overlord of Franchise/TheDCU and father of ''Comicbook/TeenTitans'' member Comicbook/{{Raven}}.
* The Anti-Monitor, ruler of the Antimatter Universe prior to and during DC's ''Comicbook/CrisisOnInfiniteEarths''.
* The Time Trapper from ''Comicbook/{{Legion Of Super-Heroes}}'' offers a somewhat different spin on this in that the dimension he rules over is the DCU itself, during its dying years.
* ''ComicBook/FantasticFour'' villain Hyperstorm is Mister Fantastic's future grandson from an alternate universe, a psychic mutant with a level of power so absurdly off the scale that he was able to conquer his entire universe without much serious effort.
* The titular VillainProtagonist of ''[[ComicBook/NeilGaimansTeknophage Teknophage]]'', by Creator/NeilGaiman, from the mostly forgotten mid-90s publisher Tekno Comix. He was a corporate dimensional conqueror purely for the purpose of satisfying his own gluttonous urgings to eat the most predatory (and thus savory) souls by making worlds so horrible that they produced assassination attempts against him. He was also a powerful telepath and especially immortal. He was also a dinosaur.
* Mojo from ''Comicbook/XMen'' rules a dimension where anyone who has the highest television ratings becomes the leader. This also applies to Mojo II, Mojo V, a babified version of Apocalypse, and in at least one alternate future the heroic Shatterstar. Since television in that dimension takes the form of deadly war games, it tends to have a high turnover in leadership.
* The titular protagonist of ''ComicBook/TheSandman'' is, as Lord of [[DreamLand the Dreaming]], a rare non-villain example. Each of his siblings has a Domain of their own, although his seems to be the only one with a significant number of other inhabitants.
** Interestingly Satan is technically not one due to then-recent events in the DCU mandating a triumvirate. Neil Gaiman plays this as an indulgence on Lucifer's part, and later subverts it: [[spoiler:When Lucifer quits and actually shuts Hell down throwing everyone out and leaving Dream the key. He goes on to lord over a nice bar.]] And then [[spoiler:he makes his own universe]] in ''Comicbook/{{Lucifer}}''. [[spoiler:But he's not very big on the 'ruling' part, basically telling anyone who lives there that his only commandment is that he is ''not'' [[StopWorshippingMe to be worshipped]].]]
* Shuma Gorath, also from Comicbook/DoctorStrange, is another one of these, as well as a MultiversalConqueror. He's even more powerful than Dormammu! ''Comicbook/TheThanosImperative'' reveals that Shuma Gorath is just one member of an entire pantheon of dimension conquering abominations called the Many-Angled Ones.
* The ''Franchise/StarWarsExpandedUniverse'' gives us Emperor Palpatine, once he gets better. When not enough power is enough, he wanted to become a god, so that he could [[GodsNeedPrayerBadly live off the Force of his followers]], and then he would conquer the universe! [[FaceHeelTurn With Luke as his high priest, of course.]]
* ''ComicBook/AstroCity'' has Krigari Ironhand, an interdimensional tyrant and emperor who's already conquered several realities before the heroes have even heard of him.
* ''ComicBook/JudgeDredd'': Judge Death, leader of the Dark Judges, is the ruler of an alternate dimension called Deadworld. He and his brethren (and the Sisters of Death) [[OmnicidalManiac culled their world of all life]] long ago before crossing over into Dredd's dimension to spread the gospel.
[[/folder]]

[[folder:Fan Works]]
* In ''FanFic/SplitSecond'', Sparkle hijacks the magic holding together the pocket dimension inside the ''Power Ponies'' comic book. She temporarily becomes a RealityWarper, with command and authority over the entire dimension and its laws of physics, but is ejected a few seconds later.
* In ''FanFic/Hottie3TheBestFanFicInTheWorld'', Emperor Vakudos is the ruler of a dimension called the Midnight Cage.
* In [[http://alaxr274.deviantart.com/gallery/36864527 Super Milestone Wars 2]], The Biggest Bad is ruuler of the dimension, Voidspace. And there's MultiversalConqueror, King Dyce, who rules over his home AlternateUniverse as well as multiple dimensions.
* In the ''FanFic/PonyPOVSeries'', all of the [[TopGod Elders]] are this to their own realms: Fauna Luster has the realm that her alicorn children live in, the Father of Alicorns has Pony Heaven, Havoc has Pony Hell, and Entropy has Oblivion (in fact it seems that they ''[[GeniusLoci are]]'' their realms). Meanwhile, all of their children have their own separate private realms within the ones controlled by Their Parents that they control themselves, but the Elders seem to be able to override that control. It should be noted that the Draconequi Elders are more neutral entities while the Alicorn Elders are fully benevolent.
** Liberalis, one of the Minor Arcana Alicorns, is a bit different from the others in that her realm isn't in the spirt realm with the others. Rather, as Concept of the Mortal World, mortal reality is her domain.
* ''FanFic/QueenOfAllOni'': If one counts Jade's [[MentalWorld mindscape]] as a dimension, then [[SuperpoweredEvilSide The Queen]], as dominant [[AnthropomorphicPersonification Aspect]] since Jade's FaceHeelTurn, qualifies, especially since she crushed Hero's rebellion. That said, Father still controls Home (Jade's soul), so she doesn't fit the criteria 100 percent.
[[/folder]]

[[folder:Literature]]
* OlderThanSteam: At least in the standard ''Paradise Lost''-influenced portrayal, {{Satan}} is the near-absolute ruler of the dimension called Hell.
* In Creator/JackVance's "[[Literature/DyingEarth Guyal of Sfere]]", the demon Blikdak is evidently foundational for the very existence of his home dimension, Jeldred - when Blikdak is destroyed, Jeldred ceases to exist. He is referred to as its "Ruler-Divinity".
[[/folder]]

[[folder: Live Action TV ]]
* ''Series/{{Angel}}'': The monks of Pylea are hinted to be acolytes of the Senior Partners.
* Dark Specter from ''Series/PowerRangersInSpace'' is the overlord of the Universal Alliance of Evil, which has already conquered most of the universe (excluding [[HumansAreSpecial Earth]]).
* Omega, from ''Series/DoctorWho'', is the absolute, [[AGodAmI godlike]] ruler of an entire universe made of anti-matter. Subverted by the fact that he's the ''only guy there''. And he wants [[SealedEvilInACan out]].
** The Celestial Toymaker occupies a separate universe which he controls absolutely.
** Time, being a dimension, makes every Time Lord one of these. Or, as of 2010, the Doctor himself, since he's the only Time Lord left.
*** It's probably best that he ''[[AGodAmI doesn't]]'' [[AGodAmI start thinking about this too much]], or show what he could really do with this status, as "The Waters of Mars" showed. It almost made the Doctor finally [[JumpingOffTheSlipperySlope go off the deep end]] and he started referring to himself as "[[AGodAmI Time Lord Victorious]]". The one thing what caused him to return to normal is Adelaide (the famous person he saved, who ''wasn't meant to be alive'') killing herself to save the world, and specifically herself, from the Doctor's hubris.
* In ''Series/{{Sliders}}'', the Kromaggs rule multiple dimensions.
* [[EldritchAbomination The Prophets]] in ''Series/StarTrekDeepSpaceNine'' are the masters of [[HyperspaceIsAScaryPlace their own dimension]], though it is unclear how large the inside of the wormhole actually is. However, they seem to display almost absolute power inside it and in the past occasionally helped the natives of the nearby planet Bajor, who in return worship them as gods.
* Glorificus from ''Series/BuffyTheVampireSlayer'' used to be one, until she got banished to earth and forced to [[SharingABody timeshare Ben's body]]. Her entire arc is about her attempt to get back to her own dimension.
[[/folder]]

[[folder: Tabletop Games ]]
* Skarn the Shaper and Tyrannon the Conqueror from the ''TabletopGame/{{Champions}}'' Universe, created by Dean Shomshak as examples of this trope. Not to mention Istvatha V'han, who doesn't call herself "Empress of a Billion Dimensions" for nothing.
* As is Omega, Lord of the Terminus from the ''TabletopGame/{{Mutants and Masterminds}}'' default setting of Freedom City.
* The Demon Lords and Arch Devils of the Great Wheel cosmology in ''TabletopGame/DungeonsAndDragons'' (used in most campaign settings of the 2nd Edition and the setting of ''TabletopGame/{{Planescape}}'') each rule over an entire layer of the Abyss and the Nine Hells. Except for Asmodeus, who has granted the other eight hells as fiefs to the other archdevils, and Graz'zt, whose realm of Azzagrat consists not only of one, but three layers, which elevates him to the same level of power as the much more stronger Demogorgon and Orcus.
* A splatbook for the Palladium Game ''TableTopGame/{{Nightbane}}'' included detailed rules on how to create your own Astral Realm (on the Astral Plane, natch) as a player character, and thus begin play as a (small-scale) Dimension Lord. The Nightlords could also count, ruling over a DarkWorld and seeking to conquer its counterpart: Earth.
* In the original editions of ''TabletopGame/MageTheAscension'', some of those who ascend actually BECAME their own extradimensional realms, where they were absolute, being both Dimension Lord and Dimension at the same time.
* In ''TabletopGame/MagicTheGathering'', this is you. And Yawgmoth was this to Phyrexia.
[[/folder]]

[[folder: Video Games ]]
* Lord Dominion in ''VideoGame/FreedomForce'', a loose pastiche of Galactus and Darkseid. A tad unusual in that the dimension he's lord over is the "normal" universe -- Earth is the ''only'' planet he hasn't conquered yet (he peppered the world with the superpower-causing agent to watch the humans destroy themselves for his amusement).
* ''VideoGame/CityOfHeroes''
** Rularuu the Ravager, a Galactus clone turned into a Dormammu clone when he was exiled to the Shadow Shard.
** DJ Zero, is a rare non-evil Dimension Lord who has turned his own private pocket dimension (possibly a sealed-off section of the Shadow Shard) into a dance club for superhumans.
** [[BigBad Tyrant]] has to qualify as well, what with ruling the entire MirrorUniverse with an iron fist and having already conquered several other dimensions, and setting his eyes on ours...
** [[SteamPunk Nemesis]] counts as well.
** By the same token, Lord of War [[MeaningfulName Hro'Dohtz]] of the Rikti a good chunk of the plot in the RWZ is trying to destabilize his control of the Rikti Homeworld.
* The various Overlords of the various Netherworlds from Creator/NipponIchi's strategy games. In particular, Laharl from ''VideoGame/{{Disgaea|HourOfDarkness}}'' and Zetta from ''Videogame/MakaiKingdom'', who're main characters of their respective games. Interestingly, the title of Overlord is inheritable -- [[AsskickingEqualsAuthority you only get to keep it until someone stronger beats the crap out of you for it]].
* While not necessarily villainous, The Elemental Lords from ''VideoGame/WorldOfWarcraft'' are an example of this. Each of them banished to their own PocketDimension of a PocketDimension that they're free to rule over to prevent their in-fighting from causing chaos on Azeroth. In ''Cataclysm'' the two that were villains were actually subservient to the expansion's BigBad Deathwing and BiggerBad [[EldritchAbomination N'Zoth]], most actually follow BlueAndOrangeMorality based on their element.
** Dimensius the All-Devouring is presented this way in ''The Burning Crusade''. He rules over a PocketDimension known as the Void (where all the Voidwalker demons come from) and emerges to devour worlds - most recently, Ka'Resh, where the Ethereals come from.
* The main villain of ''VideoGame/SoulNomadAndTheWorldEaters'' is a literal Dimension Lord as well. And the BigGood Haephnes is a token good guy example of this, since she rules the CrapsackWorld where the game takes place (it's not crapsack through her fault, mind, but manipulations of the BigBad).
* The sixteen Daedra princes in ''Franchise/TheElderScrolls '' games each rule over their own plane of ''[[VideoGame/TheElderScrollsIVOblivion Oblivion]]''; the eponymous game in the series allows the player to explore Mehrunes Dagon's and Sheogorath's planes.
* Tabuu in ''SuperSmashBros: Brawl'', [[spoiler: rules over Subspace]]. [[AllThereInTheManual In the Smash Bros. Dojo]], Master Hand is described as the Lord of the Smash Bros. world. [[spoiler:At least, until Tabuu makes it a [[PeoplePuppets puppet]]...]]
* The Guardian from the later ''Franchise/{{Ultima}}'' games. Arguably Lord British from ''VideoGame/UltimaIV'' on.
* ''Franchise/TheLegendOfZelda''
** In ''VideoGame/TheLegendOfZeldaTwilightPrincess'', Zant rules the Twilight Realm (though he usurped the position from [[spoiler:Midna]]); he then sets his sights on the World of Light. Unsurprisingly, [[HijackedByGanon Ganondorf is behind it]].
** Ganondorf is, of course, ruler of the Dark World/Sacred Land in ''VideoGame/TheLegendOfZeldaALinkToThePast''.
* [[spoiler:Dimentio]] in ''VideoGame/SuperPaperMario'' tries to take this position by destroying all the dimensions and rebuilding them in his own image.
** Also in ''VideoGame/SuperPaperMario'', Count Bleck rules from a castle floating in its own empty void-like dimension, possibly earning him the title. Even if there isn't much there.
** Also Smithy in VideoGame/SuperMarioRPG.
* The Forgotten God rules over the abyss. Later the protagonist, the titular ''VideoGame/{{Overlord}}'', can take over the god's role, ascending from an EvilOverlord to this position.
* Chzo, from the games of the ''VideoGame/ChzoMythos'', is a pain elemental that rules the World of Magick as it's King.
* ''Franchise/MortalKombat'': Shao Kahn rules as [[EvilOverlord Emperor]] of the evil, mutant-infested dimension known as Outworld. He is constantly scheming to conquer Earth. Kahn goes up to MultiversalConqueror, but [[EvilIsPetty he hates Earth for defeating him]].
* This is Ultimecia's goal in ''VideoGame/FinalFantasyVIII'', to absorb all time and space into herself and create a new universe in her image.
* In ''VideoGame/FinalFantasyXI'', [[DarkIsNotEvil Diabolos]] is the overlord of the [[DarkWorld Dynamis Dimension]].
* This was [[spoiler:Illua's]] goal in ''FinalFantasyTacticsA2'' -- [[spoiler:she made a pact with the Neukhia in order to gain more power, and planned to harness the Zellea Rift to achieve total domination over time and space.]]
* [[spoiler:[[VideoGame/FinalFantasyII The Emperor's]]]] goal in ''VideoGame/DissidiaFinalFantasy'' is to [[spoiler:arrange for Cosmos and Chaos to die while he uses a Dark Crystal to seize a portion of power from one of them (it's unclear which the Crystal takes power from)]], leaving him to rule over World B. Note that in ''Dissidia'', "World B" isn't an actual planet, closer to being an alternate dimension that rests atop the VoidBetweenTheWorlds that acts as the hub of the ''Final Fantasy'' multiverse.
* ''VideoGame/AsurasWrath'': [[spoiler: The Golden Spider[=/=]Chakravartin rules the dimension between life and death, Naraka.]]
* If you choose the Infinity Ball as your first invention in the Asura Storyline of ''VideoGame/GuildWars2'', the final boss of the story chain is one of these who has set their eye on your version of Tyria. [[spoiler:They also happen to be [[FutureMeScaresMe you]].]]
[[/folder]]

[[folder:Visual Novels]]
* As of Episode 6 of ''VisualNovel/UminekoWhenTheyCry'', the new Territory Lord of Beatrice's Fragment, the Endless [[spoiler:Sorcerer BATTLER.]]
[[/folder]]

[[folder:Webcomics]]
* Mynd of ''Webcomic/BobAndGeorge'' [[http://www.bobandgeorge.com/archives/010708c claims this when he first meets Bob, but the author admits in his notes that he's probably lying, or that his dimension is tiny.]]
* ''Webcomic/ElGoonishShive'' brings us Lord Tedd. Or, rather, did; with the NewFirstComics, he appears to have [[ChuckCunninghamSyndrome vanished from the series entirely]]. Lord Tedd was later mentioned (and {{lampshade|Hanging}}d) when Elliot was talking to Tedd's father on the phone after being attack by the Bloodgrem.
* ''Webcomic/SluggyFreelance'':
** The Dimension of Pain is ruled by an entity known only as the Demon King. The Demon King gets relatively little face time, however, and leaves most of the running of the place to his subordinate Demon Lord. (The guest strips by Ian [=McDonald=] also have the demons beholden to some kind of interdimensional fiendish bureaucracy.)
** Deplora (a "Demon Queen" but equivalent to a Demon Lord, not King) seems to rule the Dimension of Grief, except when the above mentioned guest strips introduce the Demon King's counterpart, the Grief Monarch. So probably he rules the Dimension of Grief.

[[folder:Western Animation]]
* ''WesternAnimation/FelixTheCatTheMovie'': "You think you can stop me? The Duke of Zill? The new King of Oriana? The ruler of our dimension?!"
