When the MadScientist gains enough knowledge of [[ClarkesThirdLaw technology, genetics, or the innermost workings of the laws of the universe]], as they sometimes do, and [[TakeOverTheWorld the ambition]] to go along with it, they sometimes go ahead and act on it, unleashing hordes of [[GeneticEngineeringIsTheNewNuke genetically engineered]] beings created according to [[EvilutionaryBiologist their own designs of a perfect form of life]], SuperSoldiers created and trained by them, [[RealityWarper reality-bending]] [[DoomsdayDevice physics projects]], or other such means of takeover, and thus become [[TheEmperor the supreme ruler]] of [[TheEmpire a world or galactic superpower]]. The Emperor Scientist is born.

It's important to note that not all Emperor Scientists are [[EvilOverlord Evil Overlords]] working their way on up towards becoming the next GalacticConqueror or DimensionLord. At least one out of every three you'll see will usually be a ReasonableAuthorityFigure, or at least a WellIntentionedExtremist (or KnightTemplar... or DarkMessiah) presiding over an empire that, while it still may be... well... Imperial (meaning it may not ''quite'' be TheGoodKingdom), is not evil, but instead [[IDidWhatIHadToDo does what it has to do]] to ensure the Advancement and Prosperity of Human Civilization. In rare cases, he may even be a benevolent and pacifistic ruler, which would make him a [[ThePhilosopherKing Philosopher King]].

Emperor Scientists can commonly be found hanging about in various types of {{Dystopia}}n, [[AfterTheEnd Post-Apocalyptic]], SchizoTech, FutureBadass, and UsedFuture [[TheVerse worlds]], where they will typically be the guy (or gal) in charge of one of the two [[TheEmpire Empires]] or [[BlackAndWhiteMorality warring factions]] that tend to be battling it out over what's left of those sorts of places. Bonus points if it was their superscience that actually ''caused'' [[TheEndOfTheWorldAsWeKnowIt The Cataclysm]], either indirectly or unintentionally, or directly and intentionally. Expect them to try to pursue {{Transhuman}}ism and {{immortality}}, and/or outright make the jump (but may not) to actual GodEmperor territory, using their superscience to [[AscendToAHigherPlaneOfExistence partially ascend to a higher plane of existence]] while still keeping enough of their physical form around to be visible to their subjects. It is also common for an Emperor Scientist to rule over a ProudScholarRace.

* In ''Anime/VoltesV'', [[spoiler: Prince Gohl, a man from a SlaveRace despite his RoyalBlood, overthrows corrupt Emperor Zambajil Zu after creating a SuperRobot to thwart off the Boazanian's AlienInvasion and spearheading a slave rebellion aided by the Earthlings]].
%%* Caesar from ''Return of the Overfiend''.

* ComicBook/DoctorDoom, main enemy of the ''ComicBook/FantasticFour'', with a side-order of SorcerousOverlord -- he started out as just this, but more and more stories have been building up his use of magic.
* Subverted in the original ''ComicStrip/BuckRogers'' comics. It turns out the YellowPeril villain he'd been fighting was actually a nice guy who'd just got caught up in his scientific pursuits & left the running of his kingdom to corrupt advisors.

** Warlord Julian Kintobor, AKA Dr. Ivo Robotnik from ''ComicBook/SonicTheHedgehogArchieComics''. The whole [[UnwillingRoboticisation "turn everyone into mindless robots"]] thing is only the tip of the iceberg of the mad science he unleashes to conquer the world and then enforce his rule. And then there's his AlternateUniverse counterpart, Eggman, who replaces him in the main universe after [[spoiler: the original's death]], and manages to be even more depraved in his actions.

* ''ComicBook/LegendsOfTheDeadEarth'': In ''[[Franchise/{{Superman}} Superman: The Man of Steel]]'' Annual #5, ComicBook/LexLuthor plundered the ruins of the dead Earth to locate advanced pieces of technology (including a [[ComicBook/GreenLantern Green Lantern Power Battery]] and ComicBook/DoctorFate's helmet) which he could use to conquer other planets and establish an empire.
* The High Evolutionary in the Franchise/MarvelUniverse created a race by forced evolution of animals and called them New Men. Then he created an entire planet, Counter-Earth, where they could live. Then he evolved himself into a godlike being and outgrew this trope.
* In ''[[ComicBook/LesLegendaires Les Légendaires]]'', the BigBad [[EvilSorcerer Darkhell]] is hinted to have been this in the country of [[{{Mordor}} Shiar]]: the only army he ever used for his world-conquest projects was mostly made of creatures he [[{{Magitek}} Maginetically]] [[LEGOGenetics engineered himself]]. [[spoiler:Even his own daughter Tenebris is later revealed to have been conceived through his magic.]]
* In the first ''ComicBook/{{Micronauts|MarvelComics}}'' comic series, the main villain, Baron Karza, was originally Chief Scientist of a benevolently ruled Microverse. He was a figure of high influence with the the ruling family for a thousand years due to his ability to extend life via his body banks. Then, when he was ready, he made his coup and slaughtered the ruling family (except for Princess Mari) and ruled with an iron fist except for the interference of TheResistance.
* ''Franchise/WonderWoman'' [[ComicBook/WonderWoman1942 Vol 1]]: Queen Atomia is the MadScientist ruler of her Atom World and every single one of her "subjects" has been subjected to her experimentation and forced to become mindlessly loyal to her.

* ''Fanfic/ASparkOfGenius'': A ''Series/BuffyTheVampireSlayer'', Franchise/DCUniverse and ''Webcomic/GirlGenius'' crossover has Xander, that's right. Xander become the ruler of Romania which he rapidly turns it into the leading scientific nation which all began with the infamous 'Halloween episode' turning him into the son of Agatha Heteordyne and Gilgamesh Wulfenbach, son of the man in the picture above.

* King Malbert, the ruler of the country Malaria, from ''WesternAnimation/{{Igor}}'' is a MadScientist just like all of his citizens.

%%* Ming the Merciless was more or less portrayed as such in the old ''[[Film/FlashGordonSerial Flash Gordon]]'' movie serials.
%%* Another YellowPeril example: Sax Rohmer's Dr. Literature/FuManchu, who aspired to become literal Emperor of the World by eliminating the white race..
* Then there's a rare female example from Sax Rohmer's ''Film/TheMillionEyesOfSumuru''. The scientifically-savvy title character wants to eliminate love and control an Empire where women are in charge.
* The BigBad from the second ''Film/HeroicTrio'' film fit this trope as a mad scientist taking over Hong Kong using his scientific intellect.

%%* More Creator/AEVanVogt novels had a character like this, then didn't.

* Justinian in Literature/BelisariusSeries is a subversion. He is a scientist and he is an Emperor, but he became emperor by ordinary means of political scheming and his scientific side was just a hobby until the war with the Malwa made him put his mind to new military technology.
%%* Creator/MarkTwain's ''Literature/AConnecticutYankeeInKingArthursCourt'' decides not to overthrow Myth/KingArthur's Court, finding it easier to co-opt them into his new order. The new title he devises for himself? [[spoiler:The Boss. ]]
* ''Literature/CityOfNoEnd'': Lord Pontius Arkentek, like all prior Lords of [[StarScraper Fibre Tower]], is a Sorcerer who practices SufficientlyAdvancedTechnology and leads a [[ProudScholarRace Proud Scholar]] society.

** Leto Atreides II has actually become the [[Literature/GodEmperorOfDune God-Emperor of the Universe]] to carry on with a gigantic genetic breeding experiment.
** Before him, Dr. Kynes became leader of the Fremen because of his attempts to terraform the planet Arrakis.
** The [[BrainInAJar cymek]] [[HumongousMecha titans]], philosopher kings and scientists, particularly ones that dealt with robotics, cybernetics, and artificial intelligence.
** Though not canon, the prequels state that one former Padishah Emperor, working under a false name, was an accomplished chemist that discovered the properties that made Spice so important. The original books state it was a chemist working ''for'' that emperor, so it all depends what you want to believe.
** Muad'dib himself was known as the Mentat Emperor. Considering he was the prophesied [[AscendToAHigherPlaneOfExistence Kwisatz Haderach]], this isn't surprising. Subverted in that ultimate trajectory of events was beyond even his control, and he knew it.
* Mercedes Lackey's [[Literature/HeraldsOfValdemar Mage Wars trilogy]] has both types: the evil Ma'ar, creator of the makaar, and the benevolent Urtho, creator of the gryphons (who regard him as an almost godlike being who created them as an improvement over all other sentients)

%%* This is the goal of the King in ''Anna in the Court of the King of Siam'', abbreviated to ''The King And I'' for most adaptations.
* In the ''Literature/NewJediOrder'', the [[GodEmperor Supreme Overlord]] of the [[ScaryDogmaticAliens Yuuzhan Vong]] is ideally supposed to excel at the areas of all the major Vong castes, including the [[MadScientist Shapers]], and the current Supreme Overlord, Shimrra, frequently indicates that yes, he ''is'' a skilled MadScientist. [[spoiler:Except that Shimrra is a mind-controlled shell. TheManBehindTheMan is the MadScientist]].
* In ''Literature/{{Noob}}'', the Empire, the technology side of TheMagicVersusTechnologyWar, started out as an alchemist finding ImportedAlienPhlebotinum, figuring out how it worked and using the knowledge to make new appliances. His descendants have added on to his work with the long-term purpose of gaining independence from the world's {{Physical God}}s and were eventually OfferedTheCrown of an Emperor who had no heir. Keynn, the current-day descendant, is still perpetuating the tradition via a consequential BioAugmentation program and is actually a millennia-old man who looks in his thirties thanks to the more recent discoveries on longevity.* The concept of ThePhilosopherKing from {{Creator/Plato}}'s ''The Republic'' might just as well be the UrExample in an era when what we know as Science per se is but a subgenre of Philosophy.
* In Hannu Rajaniemi's ''Literature/TheQuantumThief'' the seven Sobornost Founders are implied to have been the first group of scientists who figured out human mind uploading and quantum entanglement, and realized that this puts them above any corporation or government on Earth in terms of power if they keep it for themselves. By the time of the book is set in they rule most of the inner Solar System.
* Dayless the Conqueror in ''Literature/ShadowOfTheConqueror.'' Despite the martial title he later acquired, he always thought of himself as [[TheEngineer an engineer]] first and foremost, born just high enough to be thoroughly educated. When he set out to TakeOverTheWorld, he put his GadgeteerGenius skills to work in creating engines of war that allowed him to forge [[TheEmpire the Dawn Empire]].* ''Literature/TheSilmarillion'': Fëanor, the High King of Noldor. Likewise, Sauron in ''his'' empire, albeit more a subversion.

** Rassilon, who basically made the people of Gallifrey into the [[SufficientlyAdvancedAlien Time Lords]]. An impressive scientist even by immortal standards, he found time to invent a bewildering number of [[JustForFun/AbusingTheKardashevScaleForFunAndProfit absurdly advanced technological artifacts]]. Also had a bit of an [[ItsAllAboutMe ego]] and may have been into kidnapping beings from across space and time to fight in games for his amusement. Subsequent indolence in Time Lord society may have been a deliberate effort to curb the potential of individual members of their race from also becoming Emperor Scientist types.
*** In the Expanded Universe, Rassilon comes across as a more villainous figure, with it being heavily implied he was behind the accident that left his friend Omega trapped in a black hole. In AudioPlay/BigFinishDoctorWho he is a massive EvilutionaryBiologist, stealing the power of regeneration from the peaceful Vampires and preventing any race evolving that could threaten the Time Lords by imprisoning them in another Universe.

** The Doctor himself ends up an unconventionally ''unwilling'' version of this: by [[Recap/DoctorWhoS34E12DeathInHeaven "Death In Heaven"]] the nations of Earth have agreed that in the event of a major threat to the whole planet, a President of Earth will be installed to coordinate the defense, and the obvious candidate they've all agreed on is the Doctor. The Doctor really ''does not want'' this kind of power, so UNIT has to literally tranquilize and kidnap him to force him to do the job.

** In [[Recap/DoctorWhoS12E1Robot "Robot"]], Helena Winters is trying to become one of these. She's a blue sky researcher whose followers want to reform the world based on scientific principles, which means PuttingOnTheReich, murdering people with a robot, and trying to start a nuclear war.
** [[Recap/DoctorWhoS38E10TheTimelessChildren "The Timeless Children"]] has [[spoiler:Tecteun, a Gallifreyan scientist who discovered a [[ResurrectiveImmortality regeneration]] gene in a seemingly immortal child, extracted it and spliced it into their own DNA. They then shared it with some of their closest friends and elevated them to become the elite of Gallifreyan society, becoming the first Time Lords]].
* ''Series/{{Intergalactic}}'': Dr. Benedict Lee is the Commonworld's Director (elected head of state), who's a very ruthless scientist (it's revealed that his regime dabbles in things like {{synthetic plague}}s). It turns out that Commonworld's constitution ''mandates'' all Directors be scientists.
* In ''Series/{{Salvation}}'', [[spoiler:tech billionaire and OmnidisciplinaryScientist Darius Tanz becomes one of these after ascending to the presidency after due to his predecessor being assassinated shortly after naming him her vice president]].
%%* In ''Series/StargateSG1'', Daniel Jackson became one of these in "Absolute Power." Fortunately it was AllJustADream.
* Franchise/StargateVerse:
** The Goa'uld OmnidisciplinaryScientist Anubis and Stargate expert Ba'al also started out as scientists before ascending to the role of GodEmperor.
** In ''Series/StargateAtlantis'', the commanders and scientists of the Wraith are usually the same people (always at least the same caste); most prominently, recurring BigBad Michael and recurring LovableTraitor Todd, both of whom had great skill in genetic manipulation. (The Wraith are normally ruled by a Queen, but the Queen of Todd's Hive died and Michael created his own armies from scratch.)
** Todd also has extensive knowledge of nanite programming, which is amazing considering the last time they had to do that was 10,000 years ago. Then again, the Wraith have a HiveMind of sorts that allows one to tap into the collective psychic network. It's possible that this knowledge rests there.
%%* Dr. Chaotica, Ruler of the Cosmos! from the [[Film/FlashGordonSerial Flash Gordon]] {{Expy}} ''The Adventures of Captain Proton!'', a [[ShowWithinAShow holodeck program]] in ''Series/StarTrekVoyager''.

%%** The trope is PlayedForLaughs with Dr Chaotica in the Captain Proton holodeck program.

* In Music/JonathanCoulton's "The Future Soon," the narrator aspires to become this when his warrior robot race takes over the world. [[WoobieDestroyerOfWorlds But he'll still feel so alone....]]

* ''TabletopGame/Warhammer40000'':
** While he may also be lots of other things (DarkMessiah, CrystalDragonJesus, etc.), it is made clear in no uncertain terms that The GodEmperor of Mankind was, during his lifetime on Terra, first and foremost a scientist who spent his time laboring away in the vaults beneath the planet building space marine genetics, creating his "children", etc, and that this was the source of his great power. Seriously. [[AllThereInTheManual Read those Horus Heresy art books]].
** Technically, the Fabricator-General of Mars also counts as this since he rules the Adeptus Mechanicus, which is pretty much a self-contained, semiautonomous political entity within the Imperium and is only part of it by treaty. They are mostly left to self-govern by the other branches of Imperial government, even the Inquisition, since without the Mechanicus everyone else in the Imperium would quickly lose any ability to maintain a technological society.
** Sometimes, an Orkish [[GadgeteerGenius Mekboy]] or [[MadDoctor Painboy]] might get influential enough that they become ''de facto'' Warbosses of a Waaagh!, known as Big Mek or Painboss. Waaaghs led by Big Meks tend to be highly mechanized, sporting lots of complicated war machines and consisting mostly of Ork troops specializing in heavy firepower and vehicular warfare, while Painboss-led tribes are motely bands of apprentices Painboys and surgically-altered "Cyborks" intended mainly to collect interesting specimens for their leader. Some Warbosses consider this a sad state of affair, however, as evident by the page quote.

* Malachite from ''TabletopGame/{{Champions}}''; a super-intelligent genetic experiment GoneHorriblyRight who sets himself up as ruler of [[{{Egopolis}} the Malachite Isles]] and uses them as a base for his plans of world conquest.

* Grand Warlord Voss in ''TabletopGame/SentinelsOfTheMultiverse'', who invented a process to "gene-bind" minions to him...and used them to conquer not only his own race but several others. He was already quite high-ranking, but not quite all-powerful; his gene-bound armies changed that.
** There's also a more minor example in Baron Blade, who doesn't rule an empire but he does rule a small technologically advanced european country called mordengrad. He also has created numerous inventions and if he wasn't so single-mindedly focused on exacting revenge on Legacy, who's father killed his father, he might actually be able to take over the world.

* The Great Beings of ''Toys/{{Bionicle}}'', though they tired of the day to day workings of ruling Spherus Magna and made the Element Lords to do that part of the job for them. [[NiceJobBreakingItHero It didn't work out well]].
* ''ComicBook/BeastWarsUprising:'' Thunderwing, known as the Last Decepticon Emperor, was apparently fond of scientific innovations in his spare time, being the one who produced the Micromaster technology, and discovering the ultimate application of Targetmaster powers, which eventually led to the extermination of the Targetmasters when both Autobots and Decepticons were terrified by the results. His reign ended when he went mad and fused with his flying fortress, forcing both sides to team up to put an end to him.

*** Emperor Gestahl sets out to conquer the world with an army of high-tech-- or at least, high-{{Magitek}}-- mechanized infantry [[PoweredByAForsakenChild powered by draining the life out of magical super-beings]].

*** On the darker side of this trope, there's Garland: the de facto ruler of all Terra, he's also a powerful mage and an innovative scientist; by the time you meet him, he's successfully created an entire species of soulless drones and planted an organic siphon-refinery on Gaia [[spoiler:to slowly vaccuum Gaia's soul-cycle away]]. And then there's his greatest creations, his Angels of Death. [[spoiler:[[BigBad Kuja]] and [[TheHero Zidane]]]].
** ''VideoGame/FinalFantasyXIII2'': Hope Estheim grows up to become the director of the Academy, a science-based organization, and the Academy goes on to become the main governing body of mankind. This is subverted by the time Academia is built, however; Hope used a time capsule to jump ahead a few hundred years, and when he arrived he decided to take a strictly advisory role in the government of that era.

** ''VideoGame/FinalFantasyXIV'': One of the final emperors of Ancient Allag was Amon, a brilliant (though VERY flamboyant) scientist responsible for designing the the Crystal Tower and the artificial moon Dalamud as a power source for the empire, and created cloning technology which resurrected the first emperor, Xande to lead Allag back into a new golden age. After he let Xande take back the role of emperor, Amon took on the role of Xande's chief scientist.
* Emperor Solomon Petresun from the ''VideoGame/{{Tribes}}'' video game series was originally a scientist who invented [[AIIsACrapshoot Cybrids]], fought them into nigh extinction when they TurnedAgainstTheirMasters, made himself immortal for that purpose, and eventually took over the Earth to protect it from the Cybrid's imminent revenge. It should be noted that the above example is a {{retcon}} that first appeared in the manual to ''Starsiege''; none of the previous games (Earthsiege, it's expansion or sequel, or Missionforce Cyberstorm) mentioned the Emperor at all.
* The Pig King in ''VideoGame/{{Mother 3}}'' has aspects of an Emperor Scientist despite [[spoiler:not being a scientist at all, and just stealing all of his technology from the aliens in the previous game and/or having Dr. Andonuts do the work for him]].
* Count Raum from ''VideoGame/{{Primal}}'' for the [=PS2=].
-->'''Scree:''' He may be a vampire, sadist, and mass murderer but he's also quite the scientist by the look of things.
* The Cybran Nation in ''VideoGame/SupremeCommander'' is apparently ruled by Gustav Brackman (now a BrainInAJar ), inventor of the symbiotic AI technology that defines his people. He's the least imperial of the setting's rulers, though.
* Andrew Ryan from ''VideoGame/{{BioShock|1}}'', the "best electrical engineer of our generation" and "the bloody king of Rapture". However his actual in-game backstory indicates that he was actually an industrialist with little actual ability in regards to science.
* [[BigBad Dr. Eggman]] of ''Franchise/SonicTheHedgehog'' fame is the self-proclaimed ruler of the "Eggman Empire", with his life goal being to establish and expand it worldwide through his robotic expertise, along with reverse-engineering whatever supernatural power sources he can get use out of. There are strong implications that this Eggman Empire ''does'' already have a degree of territory, as Eggman has owned multiple companies, factories, amusement parks and cities across the franchise's history, but it isn't until ''VideoGame/SonicForces'' where he [[TheBadGuyWins succeeds]] in taking over the world... [[TheGoodGuysAlwaysWin for about six months until Sonic and pals do their usual thing.]]

%%* [[spoiler:Larkeicus]] was once this in ''VideoGame/FinalFantasyCrystalChroniclesEchoesOfTime''. Though the [[{{Precursors}} civilization]] fell 2,000 years ago.
* Kane from the ''VideoGame/CommandAndConquerTiberianSeries'' is not only the leader of a militant cult whose power rivals that of every first-world nation combined, he's also a brilliant inventor (of weapons, naturally). [[EvilPlan He started the Third Tiberium War intended to]] [[spoiler:lure aliens to Earth so he could reverse-engineer their technology]].
* High Tinker Gelbin Mekkatorque of ''VideoGame/WorldOfWarcraft''. It counts because gnomes choose their supreme leader based on his intelligence and technological skill. Also, he will [[BadassBookworm kick your ass]].
%%* Ansem of ''Franchise/KingdomHearts''. [[spoiler:Both of them. Ansem the Wise is a non-evil version (though he did become [[AntiHero somewhat]] [[GoodIsNotNice bitter]] after being deposed), while Xehanort is most certainly an evil version.]]
* ''VideoGame/FalloutNewVegas'':
** Robert House, autocratic ruler of New Vegas, InsufferableGenius, and a [[TheChessmaster a bit of a chessmaster as well]]. Prior to the war, he was one of the world's richest men, with his fortune entirely self-made through his inventions. He's also the main reason why the city and the surrounding areas survived the war relatively intact, as he nearly anticipated ''the exact day'' of the impending nuclear apocalypse[[note]]he was off by 20 hours for how much time he had, which is why the Platinum Chip was never delivered[[/note]] and spent over a decade of his life on planning for the event and its aftermath.
** Father Elijah became Elder of the Mojave chapter of the Brotherhood of Steel, not as a Paladin, like most Brotherhood Elders, but as a Scribe. He is described as a [[GadgeteerGenius genius with machines]] but he was TheSociopath with NoSocialSkills and his [[GeneralFailure tactical incompetence]] almost caused the total destruction of his chapter.
** The Think Tank of the Big Mountain facility from the ''Old World Blues'' DLC are this, being a collection of [[MadScientist mad scientists]] who survived the Great War by preserving their [[BrainInAJar brains in jars]]. Most of the Mojave's resident GoddamnBats are the result of their experiments, having escaped the facility.
** The Courier, if played with High Intelligence and maxed out skill in Science, in the Wild Card Ending and at the end of ''Old World Blues''. Bad Karma Couriers play this straight, while Good Karma Couriers are a mixture between a more benevolent version of this and a ScienceHero.
** Caesar (Edward Sallow) is a [[HardOnSoftScience rare example related to social sciences]], he was an anthropologist and a linguist working for the Followers of the Apocalypse and due to his knowledge of both, he was not only able to communicate with the Black Foot tribe, which captured he and his crew, but also to teach them tactics of warfare so they could conquer their enemies. He ended up becoming their leader and turning the tribe into the Caesar's Legion, a faction that dominated the entirety of Arizona and New Mexico and most parts of Colorado and Utah, and as well conquered 86 tribes at the time the Courier finds them in game.
* ''VideoGame/Fallout4'': The Institute is ran by these, being a [[TheDreaded shadowy cabal]] of [[MadScientist mad scientists]] hidden from the Wasteland at large. [[DeconstructedTrope Deconstructed]] in that while they have made serious scientific advances they're only scientists and as such don't always make the best decisions.

* Dr. Edward Bilstein of ''VideoGame/StarGladiator'' definitely qualifies for this. Once the top physicist for the Earth Fedearation who was responsible for the discovery of Plasma Power, Bilstein was later arrested and exiled from Earth after it was discovered that he was experiminenting on various human bodies in order to further his Plasma Power research. Breaking out of prison while placing himself into a cyborg body and gathering a cadre of fighters and forces, Bilstein had soon declared himself the emperor of his organization, known as The Fourth Empire, and that he now seeks galactic domination of the universe while continuing his MadScientist experiments.
* Dr. Weil from ''VideoGame/MegaManZero'' may have initially been a mad scientist, but via various {{plan}}s and Chessmaster moves that landed himself as ruler of Neo Arcadia, he became a full blown Emperor Scientist. However, he has more interest in making everyone suffer a fate far worse than death than actually ruling over people.
* By ''VideoGame/ResidentEvil5'', Albert Wesker has set his sights on this. Already a capable scientist, he decided to [[spoiler:exterminate most of mankind, sparing only genetically superior individuals with himself as their ruler.]]
* Kastore and three companions in ''VideoGame/MightAndMagic VII'' play a small version of this in that game (leveraging their superior scientific knowledge into becoming advisors to King Archibald, then leveraging that position to usurping the throne of Deyja), and had plans of becoming a full-scale version. Canonically, their plan failed and they never showed up again, but they ''were'' originally going to pull off the initial phase and become enough of a threat through Ancient-level science that the good guys has to resort to a magical doomsday weapon to stop them. Their 'Forge' town caused a massive backlash, however, so that plan was abandoned.
* Mao from ''VideoGame/Disgaea3AbsenceOfJustice'' effectively becomes this. The Netherworld he lives in is one gigantic demon school called Evil Academy, his father is both Overlord and Dean, and he inherits these titles by the game's end. Unlike his father, however, Mao is a MadScientist whose idea of dealing with a defeated enemy is to drag them off to his lab for vivisection.
* Grandmaster Meio from ''VideoGame/StriderArcade'' appeared over Earth one day and took over [[FailedFutureForecast a futuristic Soviet Union]]. He then led russian research teams into manufacturing weapons and machines such as a [[GravityMaster gravity-control computer]] to which take over the other half of the world, while researching the mysteries of CreatingLife on the side for [[ApocalypseHow ulterior]] [[GodhoodSeeker motives]]. In ''Strider 2'', he also dables in genetic engineering to [[BioAugmentation perfect his human race]].
* In ''VideoGame/CrusaderKings'', the Learning Focus can lead to a character becoming this; especially if they build an observatory and [[spoiler:come up with a heliocentric theory of the universe centuries before Copernicus]]. Of course Crusader Kings taking place when it does, the potential wrath of religious authorities and zealots may force the character in question to keep their discoveries a secret: openly being a scientist may (rarely) lead to a violent revocation of the Emperor part -- or Excommunication.
** The expansion pack ''Monks and Mystics'' takes this further, by allowing the player to join the [[https://en.wikipedia.org/wiki/Hermeticism Hermetic Society]] (early scientists, thinkers and mystics), who do stuff like publishing Research Papers, experimentation, building and operating laboratories, inventing stuff like gunpowder and doing chemical studies, but with somewhat supernatural elements thrown in ([[FridgeBrilliance though this can be assumed as a misinterpretation]] of natural phenomenon, [[ScienceMarchesOn as was common for that time]]).
* ''VideoGame/SidMeiersAlphaCentauri'':
** The Academician Prokhor Zakharov is the leader of the University of Planet faction and believes that the key to human survival lies on science and technology. He values research over other unnecessary things, like [[BeliefMakesYouStupid theology]] or [[MadScientist ethics]].
** Lady Deirdre Skye, the former head of hydroponics on the ''Unity'', the current leader of the Gaia's Stepdaughters faction, and a genius biologist and botanist. This helps her faction greatly in coexisting and utilising the planet's ecosystem.
* In ''VideoGame/{{Starbound}}'', the Greenfinger of a given Floran village. Greenfingers have a natural knack for technology and excellent intellects by any standards, able to create SufficientlyAdvancedBambooTechnology. Unfortunately, most of their efforts are spent dealing with the fact that the vast majority of their fellow Florans, [[GeniusDitz though not as stupid as they seem]], are [[PsychopathicManchild childish and quite frequently insane]].
* ''VideoGame/TheLegendOfZeldaBreathOfTheWild'': Princess Zelda aspires to be a benevolent version of this. An avid researcher into the recently rediscovered {{Magitek}}, she is more knowledgeable about the Ancient Sheikah Technology than any other non-Sheikah. During her excursions with Link, she also gets excited studying the various flora and fauna of the fields. But her father King Rhoam [[FantasyForbiddingFather tells her to "stop playing the scholar"]] because he thinks it distracts her from her efforts to unlock her RoyaltySuperPower to defeat the soon-to-return Ganon (efforts that have been fruitless up to that point despite Zelda's fervent dedication to the task). [[note]] [[{{Irony}} This is actually what prevents Zelda from unlocking her power]], since Zelda carries the Triforce of Wisdom and [[WrongGenreSavvy by stifling her from learning the king also stifled her power]]. [[MyGodWhatHaveIDone He only realises this as his kingdom crumbles around him, well too late for it to do any good]].[[/note]] A straighter example would be the unnamed Hyrulian monarch who had the Ancient Technology built in the first place 10,000 years ago (at least until he grew fearful of said tech), though said monarch doesn't get any real characterization.
* ''VideoGame/TheLegendOfZeldaTearsOfTheKingdom'': continuing from above, after Zelda returned one of her first official acts was having a school built. [[spoiler:And becoming one of its teachers.]]
* ''VideoGame/LittleBigAdventure'': Dr [=FunFrock=], in addition to being the supreme tyrant of the planet Twinsun, also has knowledge of cloning, which he used to create a CloneArmy which subjugates the planet under his will, and teleportation, which he uses to transport his army across the planet.
* ''VideoGame/CityOfHeroes'' Gives us quite a few, but premiere among them [[BigBad Lord Recluse]] and later Dr. Aeon. Lord Recluse originally designed his army's weaponry and gear, but later recruited Dr. Aeon for that and gave him his own city to rule in-between dooms-day operations. This is all for an organization which regularly plots to take over the world with laser-rifles, inter-dimensional transport, and cybernetic spider-mutants with psychic powers.
* ''VideoGame/TheSecretWorld'' features a well-concealed one in the form of [[spoiler:Lilith]]. Known throughout history as [[NamesToRunAwayFromReallyFast the Queen of Demons]], she's led armies of monsters into battle, been worshiped as a virtual goddess by vampires, controlled entire kingdoms [[TheManBehindTheMan from behind the scenes]], and once legitimately ruled over one of the greatest cities of the Third Age. Plus, she's also a HumanoidAbomination [[spoiler:who just so happens to be serving as the current chairwoman to the world's most powerful corporate group]]. However, what a lot of people forget -- [[MinoredInAssKicking much to her disappointment]] -- are her scientific achievements: over the course of her career, she created vampires, werewolves, the Deathless, and countless other monstrous races through the blending of magic and science, and later went on to create her own special trio of assassins by extracting a troubled young woman's multiple personalities and giving them bodies of their own. [[spoiler:In the meantime, she's currently trying to harness the awesome power of the [[CosmicKeystone Gaia Engines]].]]
* ''VideoGame/StreetsOfRogue'': You can become this. The Mayor has absolute power in the sprawling WretchedHive of the setting's MegaCity and by beating the game as a scientist you can secure that power for yourself. Technically due to the game's [[ImmersiveSim open-ended nature]] there is nothing forcing you to actually use your science to seize that power instead of just shooting everyone in a bloody revolution but the playstyle of the class does strongly push you towards a more strategic approach and completing your Big Quest objectives requires conducting experiments upon the population.
* ''VideoGame/{{Stellaris}}'': several governments such as Technocratic Dictatorship and Rational Consensus only allows for scientists as leaders. In addition, some federations choose their leaders by contests, and some of these contests are related to research.

* ''VideoGame/CryingSuns'': Oberon invented many of the advanced technologies that exist in the setting, such as the positronic chip (which made artificial intelligence possible), the first thinking machines (which would create the [=OMNIs=] on his behalf), and his immortality technology (which has kept him alive for hundreds of years). These inventions let humanity colonize the stars and allowed him to establish a galactic empire which he has ruled for seven centuries.
* ''VideoGame/MarvelStrikeForce'': Recurring villain Spider Supreme (an evil version of Spider-Man who leads Advanced Idea Mechanics) has conquered his [[ExpendableAlternateUniverse world]], [[TheBadGuyWins killed all opposition]] (both [[HeroKiller hero]] and [[EvilerThanThou villain]]) and gleefully develops superweapons for BigBad Ultimus's campaign of multiversal domination. Not because Ultimus orders him to, mind you. [[ForScience He]] just [[ForTheLulz enjoys]] [[ForTheEvulz the challenge]].
* In ''Videogame/GenshinImpact'', the nation of Sumeru is a technocracy lead by the Sages, the heads of the various schools of the Akademiya, with the Grand Sage as the overall leader of both the nation and the Akademiya. While technically they're meant to be regents for their god "Lesser Lord Kusanali", worship of Kusanali has been actively condemned due to her being scapegoated for the loss of the previous god "Greater Lord Rukkhadevata". As a group, they're treated less as a think tank of brilliant scientists and more as a group of [[DeanBitterman exceedingly pompous college deans]] with way too much power who among other things [[HardOnSoftScience also consider the arts to be a waste of time]] to the point of outlawing festivals and theater performances.

** Most governments in the ''GG'' 'verse are ruled by Emperor Scientists; small, independent technocracies seem most common, but even most of the known royals (such as Albia of Britain and the Storm King's line) are powerful [[ScienceRelatedMemeticDisorder Sparks]]. However, there are exceptions: the more traditionally noble "Fifty Families" still exert some power, but seem to be in decline as their bloodlines peter out.

* Emperor Nicholas the Puissant from the Negaverse in the ''Webcomic/GeneralProtectionFault'' webcomic. Conquered the earth (and at least one alien race) through a combination of HollywoodHacking, [[RealityWarper reality-bending]] inventions, [[MindControlDevice mind-control drugs]], and [[RankScalesWithAsskicking sheer ruthlessness]].
* In a ''Webcomic/SluggyFreelance'' AlternateUniverse "His Masterness" appears to be one of these. In the main universe, Dr. Steve and Dr. Schlock have this as their long term goal.
* The wizard emperor Brian Souballo, from ''Webcomic/OurLittleAdventure''. He implemented the process of transferring the [[OurSoulsAreDifferent Cosmic Lifestrand]] into clones grown in laboratories known as 'Training Facilities.' He has some powerful wizard lackeys who know how to use the machines but its shown that Brian or Angelo may be the only ones who truly knows how the process works.
* Kit Darling of ''Webcomic/PoppyOpossum'' is a queen and a dedicated magical ([[SufficientlyAnalyzedMagic scientific]]) researcher, not to mention an inventor. Unfortunately, she's failing to achieve what she wants in either role. As a queen, she's only a nearly powerless puppet in a more-or-less self-sufficient state, propped up by her family and [[OccupiersOutOfOurCountry resented by the local population]]; and despite being uniquely qualified for research due to a quirk of nature, she pushes herself to exhaustion and into dangerous subjects trying to find [[spoiler:a cure for her father]] without success.
* ''Webcomic/PlushAndBlood'': Doctor Brown takes over 80% of the entire world, using a peace-oriented political party and lots and lots of brainwashing. Unfortunately for him, two mercenaries decided they didn't want to live in a world where everyone drowns in liquid that destroys their free will, so they supernuke his capital city.

[[folder:Web Original]]
* [[MadScientist Doctor Insano]] of ''WebVideo/TheSpoonyExperiment'', who became President of the United States by voters being TooDumbToLive. From [[SmallNameBigEgo his view point]], however, it's just a brilliant scheme of...running and being elected. Er...'''WITH SCIENCE!!!'''
* Music/DoctorSteel wishes to take over the world and become it's emperor, by force of giant robots if necessary, so that he can turn it into a better place (for him).
* Gizmatic, the Literature/WhateleyUniverse supervillain and King of the Caribbean island country of Karedonia, complete with supervillain time shares.
* [[WebVideo/DoctorHorriblesSingAlongBlog Doctor Horrible]] aspires to this, wanting leverage his "[=PhD=] in Horribleness" and knack for invention to [[WellIntentionedExtremist solve the world's social ills]] by plunging it into "anarchy... [[ItsAllAboutMe that I run!]]"
%%* Razikale of ''Roleplay/ToRule'' is patron to both the magics and the sciences.

* ''WesternAnimation/{{Amphibia}}'': King Andrias is this, as he's as smart as Marcy (which is the main reason why he was so charmed by her) [[spoiler: and uses an army of robots and advanced technology as his personal army.]]

** Vandal Savage. In the "The Savage Time", he builds a TimeMachine and sends technology and information to his past self. Past-Vandal then uses this knowledge to take control of Nazi Germany, design [[StupidJetpackHitler crazy war machines]], and win UsefulNotes/WorldWarII.
** From the same show, Chronos becomes one, also via TimeTravel, ruling over future!Gotham (and possibly the world, it's not certain) with a gang of cybernetic Jokerz as his enforcers.
%%* Overlord from ''WesternAnimation/SpiralZone''. Yeah, from TheEighties.
* In ''WesternAnimation/SonicTheHedgehogSatAM'', Doctor Robotnik conquered Mobius with his machines, and held on to it for 11 years.
%%* Although the canon is, uh, dubious at best on his precise social role, Trevor Goodchild of ''WesternAnimation/AeonFlux'' appears to be this much of the time.
%%* Dr. Doofenschmirtz from ''WesternAnimation/PhineasAndFerb'' wants to be one of these.
%%** [[WesternAnimation/PhineasAndFerbTheMovieAcrossThe2ndDimension His counterpart from the second dimension]] did become one and believed Doof-1's inability to recognize Perry the Platypus [[ClarkKenting without the hat]] to be the reason he didn't.
* ''WesternAnimation/PinkyAndTheBrain'': The Brain, a genetically enhanced super-genius laboratory mouse, comes up with a scheme to take over the world and become this OnceAnEpisode.
%%* Zurg, the BigBad from ''WesternAnimation/BuzzLightyearOfStarCommand''.
* Ever since she ascended into an alicorn, dorky and studious [[Characters/FriendshipIsMagicTwilightSparkle Twilight Sparkle]] from ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' is a benevolent princess and she also focuses on science as well as [[BenevolentMageRuler magic]] while being [[ModestRoyalty humble royalty]].
* Most of ''WesternAnimation/{{Kim Possible}}'s'' MadScientist [[RoguesGallery enemies]] have this as a goal. It [[FailureIsTheOnlyOption never works out]] for them.

->''"Everything was a game to the Sovereigns. That's what came of a life lived completely completely disconnected from real consequences. Especially to the basilisks of the Vritra Clan, who looked at the world like one big laboratory, everything inside of it an experiment. War, disease, natural disasters...little more than opportunities for the Vritra to dissect the aftereffects."''

When the MadScientist gains enough knowledge of [[ClarkesThirdLaw technology, genetics, or the innermost workings of the laws of the universe]], as they sometimes do, and [[TakeOverTheWorld the ambition]] to go along with it, they sometimes go ahead and act on it, unleashing hordes of [[GeneticEngineeringIsTheNewNuke genetically engineered]] beings created according to their own designs of a perfect form of life, SuperSoldiers created and trained by them, [[RealityWarper reality-bending]] [[DoomsdayDevice physics projects]], or other such means of takeover, and thus become [[TheEmperor the supreme ruler]] of [[TheEmpire a world or galactic superpower]]. The Emperor Scientist is born.

* ''WesternAnimation/{{Amphibia}}'': [[Characters/AmphibiaKingAndrias King Andrias]] is this, as he's as smart as Marcy (which is the main reason why he was so charmed by her) [[spoiler: and uses an army of robots and advanced technology as his personal army.]]

** Davros from ''Series/DoctorWho'' definitely meets ALL the definitions of this trope. When his Daleks haven't turned against him, anyway. They usually do that on Thursdays.

* The concept of ThePhilosopherKing from {{Creator/Plato}}'s ''The Republic'' might just as well be the UrExample in an era when what we know as Science per se is but a subgenre of Philosophy.
* ''Literature/TheSilmarillion'': Fëanor, the High King of Noldor. Likewise, Sauron in ''his'' empire, albeit more a subversion.
%%* This is the goal of the King in ''Anna in the Court of the King of Siam'', abbreviated to ''The King And I'' for most adaptations.

%%* More Creator/AEVanVogt novels had a character like this, then didn't.
%%* Creator/MarkTwain's ''Literature/AConnecticutYankeeInKingArthursCourt'' decides not to overthrow Myth/KingArthur's Court, finding it easier to co-opt them into his new order. The new title he devises for himself? [[spoiler:The Boss. ]]

* The Risen Emperor of ''Literature/TheSuccessionDuology'' invented a form of {{Immortality}} to save his dying sister, and leveraged this into becoming GodEmperor of eighty worlds.
* ''Literature/TheWonderfulWizardOfOz'', a carnival barker from Nebraska, comes off as a SufficientlyAdvancedAlien in isolated Oz and becomes its absolute ruler through his knowledge of stagecraft and showmanship.
* The Eternal Emperor of the ''Literature/{{Sten}}'' series. A brilliant engineer, his twin discoveries of the super-efficient power source Anti-Matter Two and the means of obtaining immortality allowed him to become ruler of the known Universe for thousands of years.
* In Hannu Rajaniemi's ''Literature/TheQuantumThief'' the seven Sobornost Founders are implied to have been the first group of scientists who figured out human mind uploading and quantum entanglement, and realized that this puts them above any corporation or government on Earth in terms of power if they keep it for themselves. By the time of the book is set in they rule most of the inner Solar System.

* Justinian in Literature/BelisariusSeries is a subversion. He is a scientist and he is an Emperor, but he became emperor by ordinary means of political scheming and his scientific side was just a hobby until the war with the Malwa made him put his mind to new military technology.
* In ''Literature/{{Noob}}'', the Empire, the technology side of TheMagicVersusTechnologyWar, started out as an alchemist finding ImportedAlienPhlebotinum, figuring out how it worked and using the knowledge to make new appliances. His descendants have added on to his work with the long-term purpose of gaining independence from the world's {{Physical God}}s and were eventually OfferedTheCrown of an Emperor who had no heir. Keynn, the current-day descendant, is still perpetuating the tradition via a consequential BioAugmentation program and is actually a millennia-old man who looks in his thirties thanks to the more recent discoveries on longevity.
* Dayless the Conqueror in ''Literature/ShadowOfTheConqueror.'' Despite the martial title he later acquired, he always thought of himself as [[TheEngineer an engineer]] first and foremost, born just high enough to be thoroughly educated. When he set out to TakeOverTheWorld, he put his GadgeteerGenius skills to work in creating engines of war that allowed him to forge [[TheEmpire the Dawn Empire]].

* The Great Beings of ''Toys/{{Bionicle}}'', though they tired of the day to day workings of ruling Spherus Magna and made the Element Lords to do that part of the job for them. [NiceJobBreakingItHero It didn't work out well]].

->''”Dem Orkz got a Mek for a boss! Dat's just sad, dat is.”''

* ''In ''Anime/VoltesV'', [[spoiler: Prince Gohl, a man from a SlaveRace despite his RoyalBlood, overthrows corrupt Emperor Zambajil Zu after creating a SuperRobot to thwart off the Boazanian's AlienInvasion and spearheading a slave rebellion aided by the Earthlings]].

* ''WesternAnimation/AdventureTime'': Princess Bonnibel Bubblegum is a scientist first, a princess second. The series reveals in its first few seasons that PB built the Candy Kingdom and all of its inhabitants herself, and regularly conducts experiments [[OmnidisciplinaryScientist in various fields of science]] to better the lives of her subjects. Despite the ethical questions raised by her making a kingdom and naming herself ruler, she proves to be [[TheGoodKing the Good Princess]] and is shown to care deeply for her subjects, regularly doing whatever she can to make sure that they are protected and happy.

* ''WesternAnimation/{{Amphibia}}'': King Andrias is this, as he's as smart as Marcy (which is the main reason why he was so charmed by her) [[spoiler: and uses an army of robots and advanced technology as his personal army.]]

* Princess Bubblegum of ''WesternAnimation/AdventureTime'' ''created'' a kingdom for herself by converting biomass into candy citizens.

* Ever since she ascended into an alicorn, dorky and studious Twilight Sparkle from ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' is a benevolent princess and she also focuses on science as well as [[BenevolentMageRuler magic]] while being [[ModestRoyalty humble royalty]].

* ''WesternAnimation/SheRaAndThePrincessesOfPower'': Entrapta is shown to be this from the moment she appears. She's one of the show's smartest characters who loves science, invention, and robotics more than anything. She's shown to not give too much thought to ruling her kingdom as a result, as the soul three organic people working for her are terrified of her robots, and she defects to the Horde with minimal prompting (all it took was the promise of working somewhere where her technical expertise is appreciated).

* The Great Beings of ''Toys/{{Bionicle}}'', though they tired of the day to day workings of ruling Spherus Magna and made the Element Lords to do that part of the job for them. It didn't [[AGodAmI work]] [[NoBloodForPhlebotinum out]] [[EarthShatteringKaboom well]].

** Sometimes, an Orkish [[GadgeteerGenius Mekboy]] or [[MadDoctor Painboy]] might get influential enough that they become ''de facto'' Warbosses of a Waaagh!, known as Big Mek or Painboss. Waaaghs led by Big Meks tend to be highly mechanized, sporting lots of complicated war machines and consisting mostly of Ork troops specializing in heavy firepower and vehicular warfare, while Painboss-led tribes are motely bands of apprentices Painboys and surgically-altered "Cyborks" intended mainly to collect interesting specimens for their leader. [[VideoGame/DawnOfWar Some Warbosses consider this a sad state of affair, however.]]

** Robert House, autocratic ruler of New Vegas, InsufferableGenius, and a [[TheChessmaster a bit of a chessmaster as well]]. Prior to the war, he was one of the world's richest men, with his fortune entirely self-made through his inventions. He's also the main reason why the city and the surrounding areas survived the war relatively intact, as he anticipated ''the exact day'' of the impending nuclear apocalypse and spent over a decade of his life on planning for the event and its aftermath.

* ''VideoGame/TheLegendOfZeldaTearsOfTheKingdom'': continuing from above, after Zelda returned one of her first official acts was having a school built.

* ''VideoGame/TheLegendOfZeldaBreathOfTheWild'': Princess Zelda aspires to be a benevolent version of this. An avid researcher into the recently rediscovered {{Magitek}}, she is more knowledgeable about the Ancient Sheikah Technology than any other non-Sheikah. During her excursions with Link, she also gets excited studying the various flora and fauna of the fields. But her father King Rhoam [[FantasyForbiddingFather tells her to "stop playing the scholar"]] because he thinks it distracts her from her efforts to unlock her RoyaltySuperPower to defeat the soon-to-return Ganon (efforts that have been fruitless up to that point despite Zelda's fervent dedication to the task). [[note]] [[{{Irony}} This is actually what prevents Zelda from unlocking her power]], since Zelda carries the Triforce of Wisdom and [[WrongGenreSavvy by stifling her from learning the king also stifled her power]]. [[MyGodWhatHaveIDone He only realises this as his kingdom crumbles around him, well too late for it to do any good]].[[/note]] A straighter example would be the unnamed Hyrulian monarch who had the Ancient Technology built in the first place 10,000 years ago, though said monarch doesn't get any real characterization.

* Emperor Andross from the ''VideoGame/StarFox'' games, who invented all kinds of crazy warships and bio-weapons to conquer the Lylat system, and incidentally turned himself into a giant brain for some reason.
