->''Choirs of daemons howl in salute as they sense his flagship exiting from warpspace at the edge of the system. Chains of cities across the surface of the planet are set ablaze in welcome as his battle barge slides into orbit. Thousands of slaves are sacrificed in celebration as he sets foot upon the surface, the very earth beneath him soaked in the blood of his victims.''
-->-- ''ComicBook/{{Bloodquest}}'', ''TabletopGame/Warhammer40000''

Generally below the DimensionLord but above TheEmperor and the EvilOverlord lies this guy.

Maybe he wants to conquer the universe. Maybe he wants to [[OmnicidalManiac kill everyone in it]]. Whatever he does, he'll be crazy-mad [[PhysicalGod powerful]], so it's going to take a whole [[HeroesUnlimited boatload of heroes]] to take him down.

Sometimes he'll have an army to back him up, but more often than not, he'll work alone, relying on his incredibly vast cosmic powers to crush the good guys. Many have both.

These characters are usually male, although modern works are offering more and more females the opportunity to enslave entire galaxies. Distinguishable from the EldritchAbomination in that these guys have somewhat human motives for what they do. Often, this is what the SealedEvilInACan turns into once it's unsealed. Take this UpToEleven, and you get a MultiversalConqueror.



[[folder:Anime & Manga]]
* The Holy Nightmare Corporation, the BigBad of the ''Anime/{{Kirby|Right Back At Ya}}'' anime, is [[InformedAbility stated]] to have ''already'' successfully conquered the universe and defeated at least one major [[LaResistance resistance movement]]... but a KidHero is shaping up to take them down.
* King Vega from ''Anime/UFORoboGrendizer'', one of the ''Anime/MazingerZ'' sequels. He was emperor of a warrior race and ruled over a planet was dying due to overexploitation from one of its resources -a radioactive and highly unstable ore named Vegatron-, so he started to conquer other planets to find another world to settle on. He used to say his army was the most powerful one in the universe.
* ''Franchise/DragonBall'' examples:
** Freeza - immensely powerful to the point of being considered invincible, he nonetheless [[OrcusOnHisThrone usually has his army to do the actual fighting]]. Known for exterminating large portions of planets' populations and enslaving the rest, or simply killing off the ''entire'' population and selling the planet to the highest bidder, his name was feared by all spacefaring civilizations throughout the galaxy. The fact that he could [[EarthShatteringKaboom blow up your planet on a whim]] just served as further incentive to surrender.
** Lord Slug from ''Anime/DragonBallZLordSlug'' is a CompositeCharacter of Freeza and King Piccolo from early ''Manga/DragonBall''.
* Zoltar from ''Anime/BattleOfThePlanets'' (and ''only'' Battle Of the Planets. The original ''Gatchaman'' was set entirely on Earth, villains and all!)
* Zarkon and his son, Lotor from ''Anime/{{Voltron}}.''
* Reinhard von Lohengramm, the protagonist of ''Anime/LegendOfGalacticHeroes'' is a rare heroic example of this trope (although he ''might'' count as an AntiHero. Might.) He wants to unite all of space under his rule. The thing about it is that his Empire is actually pretty awesome because he's a superb ruler. They're opposed by the democractic Free Planets Alliance. A huge topic in the series is basically the conflict between a ''good'' autocracy and a ''rotten'' democracy.
** Subverted twice: first, Yang Wen-Li, his rival from the Free Planet Alliance is a much better conqueror than him (a pissed Yang can [[spoiler: fight Reinhard to a standstill with a tenth of his troops]]), the only thing stoping him from conquering the galaxy being his lack of ambition and distaste for playing political games; and second, the [[spoiler: real GalacticConqueror is not Reinhard but his wife, Hilda, the only character in the verse who actually manage to outgambit Yang]]
* Empress Ramaj from ''Literature/CrestOfTheStars'', like above-mentioned Reinhard von Lohengramm, is also a rare heroic example. She is an empress of a militaristic feudal space empire that conquers every world it encounters and the show revolves around her empire's war against TheAlliance of democratic states. The goal of TheEmpire is to subjugate humankind to its benevolent authoritarian rule and lead it to an era of endless peaace and prosperity. She is not the protagonist, though, but a BigGood and grandmother of the protagonist.
* The aptly-named Sailor Galaxia from ''Franchise/SailorMoon''. No points for guessing what is [[EarthIsTheCenterOfTheUniverse that last planet]] she needs to conquer to complete her quest.
* ''Manga/ToLoveRu'' has Lala's father being one of these.
* Boros form ''Anime/OnePunchMan'' is an expy of [[Anime/DragonBallZ Freiza]] and conquered most of the universe. He grew bored of having no challenge but came to Earth to fight Saitama after a prophet pointed him in the right direction.

[[folder:Comic Books]]
* Franchise/MarvelUniverse:
** This is a general characterization for most cosmic-centric supervillains within the Marvel Universe. Some prominent terran-centric supervillains like Doctor Doom and Kang The Conqueror occasionally branch off into this trope, when their ambition exceeds their normal boundaries.
** ComicBook/{{Thanos}} of Titan has embodied this trope in the past, with his obsession with ultimate power and Death being his primary motivations. His first appearance had him conqueroring his home planet of Titan with similar plans for Earth. CharacterizationMarchesOn, however, and he is now simply a GeniusBruiser [[OmniDisciplinaryScientist Omni-Disciplinary]] MadScientist whose motivations range from ItAmusedMe to OmnicidalManiac, the latter to impress his girlfriend (or, currently, because she dumped him and he's going to take it out on everyone else).
*** And when we mean "Obsession with Death" we mean the StalkerWithACrush kind of obsession. Said girlfriend ''is'' Death.
** Annihilus, The Supreme Intelligence, at times the Skrulls and, mostly whenever Lilandra isn't in charge, the Shi'ar emperor/empress tends to fill this role too, especially when Vulcan was in charge.
** [[OurGiantsAreBigger Terminus]] the cosmic strip-miner.
** A large percentage of the [[{{Kaiju}} giant monsters]] from Marvel's pre-super hero days were alien invaders (Goom, his son Googam, etc.). Even [[WhenTreesAttack Groot,]] who has since done a HeelFaceTurn, started out this way.
** A lesser known one is Arm'Chedon(Armeggedon), an enemy of TheHulk from the 90s and leader of the Troyjan Empire. He was so busy conquering planets that he didn't even notice he had two sons running around until one of them got killed harassing the Pantheon(Hulk's team at the time) on Earth, and the other died in trail by combat with the Hulk. He swore vengeance, but got all of one appearance until well over a decade later.
* Franchise/TheDCU:
** Across countless worlds, for countless eons, not a voice is raised in hope or joy. Across these worlds, these infinite lands throughout the cosmos, there is only ComicBook/{{Darkseid}}.
** ComicBook/{{Brainiac}}. His goals and methods have varied a lot over the years, but he still usually fits this trope.
** Mongul (both of them), the despotic ruler of War World. Galactic domination has always been his end game.
** Despero and Kanjar Ro are much lower-tier versions of this trope. Kanjar Ro is usually treated as a [[VillainDecay joke villain]] these days.
** Starro the Conqueror, although his more powerful appearances drift him more towards being an EldritchAbomination.
* Megatron from the various ''{{Franchise/Transformers}}'' canon.
* ''ComicBook/KhaalTheChroniclesOfAGalacticEmperor'' is ExactlyWhatItSaysOnTheTin, but granted he doesn't start out as one in the comic proper: he is introduced as a fearsome warlord in a prison spaceship that gets invaded by superior aliens, but Khaal manages to kill their leader and take control of the invaders. He turns his attention to the rest of the galaxy and aims to conquer every world in his way. [[spoiler:The comic ends with him finding and conquering ''[[DownerEnding Earth]]'']].

[[folder:Fan Works]]
* Warlord Kroz from ''FanFic/Tech10Rebooted'' is a NobleDemon variety of this, having conquered around 72 planets on his quest to find a WorthyOpponent, but simply leaving them alone afterwards.
* In ''Fanfic/TheShapeOfTheNightmareToCome'' and ''Fanfic/TheAgeOfDusk'', Abaddon finally manages to take over all of Segmentum Obscurus.

[[folder:Films -- Live-Action]]
* Palpatine from ''Franchise/StarWars'' is the consummate example of this trope, though he did it through pure {{Magnificent Bastard}}ry rather than outright force. [[spoiler:He got ''voted'' into absolute power, after masterminding a ''civil war'' after a millenium of peace (in which he was secretly the leader of both sides), resulting in him receiving ''popular support'' for his authoritarian reforms. By the time he declared himself Emperor, he already had absolute control of the Republic...or, as he declared it, '''[[PunctuatedForEmphasis the first! Galactic! EMPIRE!]]''']]
-->'''Padmé Amidala:''' So this is how liberty dies: with thunderous applause...
* Ming the Merciless from the ''Film/{{Flash Gordon|1980}}'' film is referred to as the Emperor of the Universe and the Galaxy. The fact that he can casually cause moons to collide with planets and rain down "natural" disasters on every solar system when he wants to test them definitely places him on the level of Galactic Conqueror. However, he only exercises direct control over his homeworld and it's moons.
* The Lord Marshal, leader of the Necromongers from the ''[[Franchise/TheChroniclesOfRiddick Riddick]]'' franchise. They're basically space-faring KnightTemplar crusaders led by a "holy-half dead" leader who move from planet to planet, converting anyone they can find and killing anyone who refuses.
* The Beast in ''Film/{{Krull}}.''
* ''Franchise/MarvelCinematicUniverse'':
** Thanos - while he usually [[OrcusOnHisThrone has others do the grunt-work for him]], he is widely regarded as the most powerful being in the universe, and commands at least one army of killer cyborgs and a retinue of elite warriors. His ultimate goal is to assemble the six Infinity Stones and use their power to wipe out ''half'' of all sapient life as a twisted form of PopulationControl.
** ''Film/ThorRagnarok'' revealed that [[spoiler:Odin, of all people]] used to be this, before changing their ways. The BigBad even noted how she used to be their favored tool of conquest, and lamented that such glorious days were long gone.

* Emperor Zhark in the ''Literature/ThursdayNext'' series. In his book series he regularly destroys and enslaves whole worlds. In person he's a pretty nice guy, though he does tend to overreact a bit, like responding to a shoot out in a Western book by deploying {{Space Marine}}s.
* Paul Atreides, the hero of ''Literature/{{Dune}}'', brought his dynasty to supreme power by threatening to destroy the all-important Spice.
* The Mule, in the ''Literature/{{Foundation}}'' series, damn near scuttles the Seldon Plan, as psychohistory can't predict things like mutants with mind control powers and attitude problems.
* The Real goal of Mesa in ''Literature/HonorHarrington'', as part of their goals overthrowing the anti-transhuman culture.
* In ''Literature/PleaseDontTellMyParentsImASupervillain'', the mentioned but unseen Conquerors seem to be an entire race of these.

[[folder:Live-Action TV]]
* ''Series/StargateSG1'':
** The Goa'uld as a whole already control most of the Milky Way Galaxy, but the most ambitious Goa'uld [[EvilOverlord System Lords]] usually try to conquer all of the galaxy by absorbing the territories of their rivals, assuming the BigBad mantle in the process. Successively, Apophis, Anubis, and Ba'al came the closest to actually succeeding.
** As well as the Ori, who have already conquered one galaxy. They're [[AscendToAHigherPlaneOfExistence ascended]] EnergyBeings who rule through a ReligionOfEvil called Origin, and build an armada to embark on a crusade to convert the Milky Way.
* ''Series/StargateAtlantis'':
** The Wraith in the Pegasus Galaxy, although they don't so much rule as they do ''[[ToServeMan feed]]''. Also, the Wraith do a lot of fighting amongst themselves, on account of there not being enough food to go around. Thus, no one person (or hive queen) actually controls their galaxy.
** The former Wraith named "Michael" became such a threat in his own right in the later seasons. After he started his Hybrid project he started lusting after power for its own sake. His end goal became to supplant both humans and Wraith with his Hybrid minions by annihilating everything else.
* ''Series/DoctorWho'':
** The Master in the classic series, whenever they weren't just messing with the Doctor ForTheEvulz. In the revived series, the John Simm Master planned to establish a "New Time Lord Empire" in his first appearance, taking over Earth and building a fleet of warships during "the year that never was". The Doctor, Martha and Jack stopped him before he could launch his first attack.
** Davros, creator of [[AbsoluteXenophobe the Daleks]], is the OmnicidalManiac variety. He comes close to succeeding in "[[Recap/DoctorWhoS30E12TheStolenEarth The Stolen Earth]]"/"[[Recap/DoctorWhoS30E13JourneysEnd Journey's End]]".
* Pretty much any villain race in ''Franchise/StarTrek'' at some point has aspirations of galactic conquests. But as far as individuals in the series go, the Borg Queen is the best example.
* His Divine Shadow in ''Series/{{Lexx}}''.
* ''Franchise/SuperSentai'' and ''Franchise/PowerRangers'' have a few:
** Dark Specter from ''Series/PowerRangersInSpace''. He is also a DimensionLord, and so badass that [[spoiler:it takes a [[EarthShatteringKaboom planet-destroying missile]] and more to take him down.]]
** Emperor Akudos Gil, head of the Zangyack Empire in ''Series/KaizokuSentaiGokaiger''.
** Don Armage, the ruler of the Space Shogunate Jark Matter, who has conquered pretty much the entire galaxy, including earth, in ''Series/UchuSentaiKyuranger''.

[[folder:Myths & Religion]]
* Xenu in the ChurchOfHappyology conquered many worlds and dropped his excess population into Earth's volcanos, leading to many of the evils that plague mankind.

[[folder:Tabletop Games]]
* ''TabletopGame/{{Traveller}}'':
** Cleon I, founder of the Third Imperium. In something of a subversion, he not only succeeds, but his empire is actually a more-or-less nice one once it is created - whatever one can say of ''[[DirtyBusiness how]]'' he created it. Cleon was a skillful politician, businessman, and diplomat. He knew when to [[ManipulativeBastard entice]], when to [[GunboatDiplomacy bludgeon]], and how to [[TheChessmaster weave together multitudinous plans]], and in general he was a very MagnificentBastard.
** Albadawi might count. He was a FourStarBadass who pretty much won the Interstellar Wars himself. In his case he was acting as a servant of the Terran Confederation rather then for his own ambition.
* ''TabletopGame/Warhammer40000'' has more than its fair share of these, some evil... some ''[[BlackAndGreyMorality really]]'' evil. (See page quote.)
** The most successful was undoubtedly [[MessianicArchetype the Emperor of Man]], the founder, and later god of [[TheEmpire the Imperium]], the setting's [[BlackAndGrayMorality "good" guys]]. The Imperium had been the at its most reasonable and expanded most rapidly under his direct rule, growing from the solar system to spanning most of the galaxy in just a few short centuries (in spite of their life extending technologies, the Emperor was already immortally youthful, purportedly ''38,000 years old'' when he founded the Imperium). It was also secular, reasonably tolerant of mutants and nonhostile aliens, and presumably had reasonably efficient governance. The the Horus Heresy happened and the Emperor was interred into the [[ImmortalityInducer Golden Throne]] to survive and lost most ability to communicate; he more or less as a figurehead and his Imperium became a psychotic, dystopian, totalitarian, theocratic empire. The Imperium never fully recovered after that, while it still makes some gains in territory and technology from time to time, it sits somewhere between stagnant and failing by inches. Between most of its resources being sucked up by wars on all sides, including the occasional civil war between parts of it and the occaisional galactic crisis, the Imperium, and humanity's last hope (suchas it is), tottering on between a lasting victory and permanent collapse has been a lasting theme of [=40K=].
** The other [[ALighterShadeOfGrey "good guys"]] of 40k, the [[TheFederation Tau Empire]], also have this as a goal, believing it to be a part of their manifest destiny. Though they have a long, long way to go. They currently sit have a tiny, yet densely packed empire on the opposite side of the galaxy, preferring to use diplomatic, economic, and political means to bring other species into their empire, including Human-held worlds left behind or left to their own devices. However, [[DependingOnTheWriter depending on who you listen to]], they might be the optimistic, hopeful beacon of reason and tolerance they present themselves as, or they might be an Orwellian, authoritarian society ruled by a caste of scheming, charismatic masterminds [[CrapsaccharineWorld given a bright coat of paint]]. A recurring theme is that the Tau are naive and overly eager to extend a hand of friendship, sometimes to their own peril. However, most of the other races are more interested in some combination of killing, raping, torturing, or just eating everyone. BlackAndGreyMorality indeed.
** Not to mention Abaddon the Despoiler, Warmaster of Chaos. The foremost of Chaos Lords, and blessed by all the Chaos Gods. He is recognized by the Imperium as an existential threat, and they devote a great deal of resources and manpower to keeping him and the rest of the hordes of Chaos contained to the [[NegativeSpaceWedgie Eye of Terror]]. He led thirteen Black Crusades which broke out including his [[TabletopGame/BattlefleetGothic 12th to the Gothic Sector]] against the Imperium. He'll show up to harass the Imperium once in a while, and every now and then he'll launch a Black Crusade to collect superweapons and to weaken and undermine the Imperium around the Eye as part of the LongGame. ({{Fanon}} likes to think of these as [[GeneralFailure repeated failures]], though it wasn't until relatively recently [[{{Revision}} that we learned about them in detail]]. And before that point, any permanent, meaningful victories against the Imperium was [[FailureIsTheOnlyOption outside the bounds of allowed narrative]].) Now, he's gathering up his weapons and unifying the forces of Chaos at a level unprecedented for nearly 10 millennia for the [[ThirteenIsUnlucky 13th Black Crusade]] to make an assault on Terra after all this time, to finally succeed in what Horus didn't.
*** That said, [[GreaterScopeVillain Chaos itself]] hopes to engulf the galaxy, and would if their mortal followers ever succeed in bringing down the Emperor. Chaos is broken up into four major gods, each representing its own unique portfolio and domain, and possibly lesser gods of an unknown number. Hypothetically, they could take over realspace ''right now'', but such is the nature of Chaos is that their energy and attention is mostly spent against one another in the Great Game, a war that, by definition, is [[ForeverWar destined to never end]].
** The Craftworld [[SpaceElves Eldar]] dream of retaking their former place as the masters of the galaxy. The more realistic ones know that the odds of them ever doing so are almost zero, but keep fighting anyway since it beats laying down and accepting extinction.
** Surprisingly {{Averted}} with the [[AlwaysChaoticEvil Dark Eldar]], the most vicious and sadistic of the factions ([[CrapsackWorld which is saying something]]) and the only Eldar faction who has managed to thrive, who don't want to bother with conquering the galaxy. Yes, they do make regular raids into realspace for [[VampiricDraining food]] and [[MadeASlave slaves]] (often one and the same), and will occasionally make a grab for resources or territory. But they don't bother since being in realspace for an extended period is a hazard for them: the Chaos God Slaanesh is constantly "sipping" out their souls, the effect is strongest in realspace, and dying out there carries the most risk against revivification should they fall in battle. That aside, they're having too much fun or too occupied in their home city of Commorragh, where murder and intrigue is rife and the kabals (something between a noble house and a pirate syndicate) are too busy competing to undermine or exterminate one another. The other subgroups of the Dark Eldar, [[MadScientist Haemonculus covens]], [[GladiatorGames wych cults]], [[HoverBoard Hellion gangs]], and the [[EliteMooks Incubus shrines]] typically lack the resources to go out into realspace and attach themselves to kabal raids as mercenary cohorts.

* The Zerg Overmind from ''VideoGame/StarCraft'' wants to assimilate all life in the universe into the Zerg Swarm.
** Later succeeded by his [[TheDragon Dragon]] Kerrigan, who is -- by her own words -- ''"pretty much the queen bitch of the universe"''.
** ''VideoGame/StarCraftII'' The Dark Voice [[spoiler: the true master mind who programed the Overmind to attack the Xel Naga, and lead the Zerg into assimilating the Protoss to create Zerg/Protoss Hybrids. His grand scheme is to wipe out all life in the galaxy so he and his Hybrids will rule it.]]

** Before the ''Galaxy'' games, he planned to use the power of the Star Children to take over the universe in ''VideoGame/YoshisIslandDS''.
* ''VideoGame/KnightsOfTheOldRepublic'' has both Darth Revan in the BackStory of the game and Darth Malak as the current BigBad. In TheDarkSide [[MultipleEndings ending]], the PlayerCharacter becomes one.
* ''VideoGame/FreedomForce'' has Lord Dominion.
* ''VideoGame/{{Civilization}}'' ''InSpace''! games like ''VideoGame/MasterOfOrion'' usually have this as an option for winning the game.
* In ''VideoGame/FreedomPlanet'', by the time [[BigBad Arktivus Brevon]] makes his way to [[PlanetOfHats Planet]] [[{{Wutai}} Avalice]], he's already conquered a large swath of the galaxy. Taking the Kingdom Stone hidden on Avalice would allow him to continue his conquest unopposed.
* Sargeras the Fallen Titan from the ''VideoGame/{{Warcraft}}'' universe, whose goal is to lead the [[LegionsOfHell Burning Legion]] to destroy the entire universe.
* ''Franchise/MassEffect'': [[spoiler:[[EldritchAbomination The Reapers]]]] are an interesting variation of this. [[spoiler:In a way, they already control the galaxy, as it is a gigantic coral where they alow humanoid races to develop and return to harvest them every 50,000 years. The entire ancient network of self-repairing hyperspace jumpgates and the gargantuan space station at its center, and most of the highly advanced technology found in ancient ruins was made by them for the sole purpose of creating new galactic civilizations that provide exactly what they need.]]
** Javik is a WellIntentionedExtremist, mundane version of this. The plan was to get a million protheans to survive the Reaper Harvest by hiding in stasis, then force the primitive races into servitude against the Reapers. Unfortunately, that plan got royally screwed.
* The [[HiveMind Gravemind]] and its [[TheVirus Flood]] forces in ''Franchise/{{Halo}}''. According to its words, the Flood had already conquered galaxi''es''-worth "of flesh and bones" and now were planning on conquering the Milky Way. Despite the courage and highly advanced technology of the Forerunners, the Flood could only be slowed down, until the former made the decision to [[HeroicSacrifice to sacrifice themselves and all non-indexed sentient life in a effort to starve them to death]]. 100,000 years later, the Gravemind (being effectively immortal) is finally reformed but was again defeated, this time by humanity and the Arbiter-affiliated Elites, who [[EnemyMine put aside their differences]] and use [[spoiler:the Ark and the replacement Halo 04 to lure in and destroy the Gravemind and all the Flood it could muster before the infection became too big to stop]]. However, given that there are still a lot of Flood in storage on various Forerunner research facilities, and the fact that the Flood are ''extra-galactic'' in origin (hence why none of the before-mentioned samples were simply destroyed), the Gravemind is likely not finished yet.
* BIOS from ''VideoGame/ForgottenWorlds'', who has created ''gods'' to serve as his enforcers as he travels the galaxy, conquering and reducing worlds into barren wastelands.
* The Grandmaster from ''VideoGame/{{Strider}}'' and its sequel, who couples it with his desire to create new lifeforms at will to [[AGodAmI become a new god]].
* [[NamesToRunAwayFromReallyFast Genocide]] / [[DubNameChange Scumocide]] from ''VideoGame/CaptainCommando'' has already established a Criminal Syndicate of [[BioAugmentation bio-engineered]] super criminals that has taken over the entire galaxy by the time the game kicks in.
* One boss in ''VideoGame/VisionsAndVoices'' is called the "Minor Galactivore." This guy is not even ''close'' to being the final boss.
* Orbulon from ''VideoGame/WarioWare'' tries to be this in the first game. He ''really'' sucks at it.
* In the [[VideoGame/KirbysDreamLand2 first]] [[VideoGame/KirbysDreamLand3 two]] games of the ''VideoGame/{{Kirby}}'' Dark Matter Trilogy, Dark Matter threatens to take over, respectively, Dream Land and all of Pop Star. By ''[[VideoGame/Kirby64TheCrystalShards Kirby 64]]'', it threatens Pop Star and all of the nearby planets.
* ''[[Franchise/{{Metroid}} The Metroid Prime Trilogy]]'' has [[HumanoidAbomination Dark]] [[EvilCounterpart Samus]], who finally settles on trying to become this after [[MindControl taking control of the Space Pirates]] and [[AGodAmI having them treat her as a goddess]]. How? Using the [[GeniusLoci planet Phaaze]], the source of all [[SentientPhlebotinum Pha]][[ToxicPhlebotinum zon]], to infect all the planets in the galaxy with it to either kill the inhabitants or turn them into corrupted monsters under her control.
* From ''VideoGame/{{Battleborn}}'' is [[BigBad Lothar Rendain]], [[TheEmperor leader of the Jennerit Imperium]] who has decided to ally with [[HordeOfAlienLocusts the Varelsi]] and aid them in their destruction of the universe on the promise that he and those who follow him would be spared from the universal end and be granted "ascension" to "the passage" to "the other side".
* ''VisualNovel/{{Sunrider}}'' has Veniczar Arcadius, the [[MalevolentMaskedMan masked dictator]] of the galactic superpower PACT. He already controls a good chunk of the galaxy in this capacity and is keen on taking over the rest, steamrolling the independent worlds of the Neutral Rim with his overwhelming military might.
* In ''VideoGame/{{Stellaris}}'', this can be a goal for many an interstellar empire. However, in terms of characterization, the Great Khan of ''Apocalypse'' most clearly qualifies. They are a [[VisionaryVillain visionary leader]] who unites first the squabbling marauder tribes, and then attempts to turn the rest of the galaxy into satrapies. How well this goes varies; sometimes they succeed (until [[KeystoneArmy their inevitable demise undoes most of their work]]), and sometimes they pick a fight with [[HigherTechSpecies a Fallen Empire]] well before they stand a chance of not being wiped out.

* The [[Franchise/{{DCAU}} DC Animated Universe]] covers many different generations of heroes, across different decades (even centuries) and facing varied and divergent foes, but none can compare to the ultimate BigBad, whose mere presence is enough to cow raging mobs of bloodthirsty beasts.

** "The Greater Hater" introduces Lord Dominator, a villain who [[AlwaysSomeoneBetter seems to out-match Hater on every level]] (a bigger ship, better weapons, and an army of ruthless MechaMooks instead of [[SurroundedByIdiots the bungling Watchdogs]]).
** The galaxy is actually full of these, all competing to get the highest ranking on "Galactic Villain Leaderboard". Such characters include [[TotallyRadical Emperor Awesome]], [[AnthropomorphicFood Sourdough the Evil Sandwich]], [[SinisterGeometry The Black Cube of Darkness]], [[LaughablyEvil Dr. Screwball Jones]], and countless others. This even includes some [[OfficialFanSubmittedContent fan characters]].
* Aku of ''WesternAnimation/SamuraiJack'' has not only conquered Earth, but the galaxy at large, which is why the BadFuture he rules over is filled with aliens.

* Not content with ruling most of the earth, Richard Branson has founded Virgin Galactic, a company which according to Wiki/TheOtherWiki intends to provide sub-orbital spaceflights to the paying public, along with suborbital space science missions and orbital launches of small satellites but come on, we all know what it's really for.
* We have space stations, probes have landed on Mars and collected rock samples, there is an American flag on the moon. Scientists are talking about terraforming planets. It won't be long now....
