->'''Spinnerette''': Dr. Universe, wait! At least tell me something! You were a respected scientist, your work on the Cherenkovkirby Reactor was going to benefit all of mankind! Why would you turn into a supervillain? ''WHY?!''\\
'''Dr. Universe''': I read an Creator/AynRand [[TakeThat novel]].
-->-- ''Webcomic/{{Spinnerette}}''

The Evil Genius is obviously intelligent, and is the one building the WaveMotionGun or shipping the nukes into the country or resurrecting the LostSuperweapon or what have you. This character is usually the one that will demonstrate how to use a particular MacGuffin. They're usually a MadScientist, a [[TheStrategist military tactician]], a specialist in a particular field (such as computers or electronics), or has ties to TheGovernment (or a combination), so they're in the best position to deliver the goodies to the EvilOverlord. In medieval fantasy settings, this role is often played by an evil strategist, rogue/spymaster, or a dark wizard (provided they aren't also the BigBad). The Evil Genius is the most likely person to be the BigBad because they are the brains behind the EvilPlan.

Although they tend to be the most intelligent, that intelligence usually never translates into political savvy, business acumen or leadership ability all of which rely more on street smarts, people skills and charisma than just technical knowledge. As a result, the evil genius is usually never the top dog. But he's still closer to the top than most.

The Evil Genius is a standard character in the FiveBadBand dynamic. They're usually rather high-ranked, commonly below TheDragon but above the QuirkyMinibossSquad. They are almost exclusively male except in fiction that either has an [[ImprobablyFemaleCast unusually high female ratio]] or a female motif for its villains. Because an Evil Genius is not easily replaced and because he's not a realistic contender for the number one spot, his position is often more secure and less precarious than that of The Dragon or even the BigBad. He usually doesn't need to worry about nasty things like KlingonPromotion eliminating him from the game.

Just like his GoodCounterpart in the FiveManBand (which is TheSmartGuy), this character is very frequently described as physically unimposing. Within the FiveBadBand, the Evil Genius tends to rank lowest in the likeability department both InUniverse and with the fan base.

Prone to being BadBoss'd when the [[GambitRoulette ridiculously circuitous plan]] inevitably [[YouHaveFailedMe fails]] or if they are [[YouHaveOutlivedYourUsefulness no longer needed and viewed as a liability]]. Whether this leads to a MistreatmentInducedBetrayal (and by proxy a HeelFaceTurn) is another matter.

An Evil Genius who is also the BigBad will frequently be TheChessmaster and/or a ManipulativeBastard, maybe even to the point of [[MagnificentBastard magnificence.]] They can also show up as members of a QuirkyMinibossSquad, but then are usually made significantly less effective by virtue of their quirkiness. They often are also MorallyAmbiguousDoctorate. Some even qualify as FourEyesZeroSoul.

Not to be confused with the DiabolicalMastermind simulation game ''VideoGame/EvilGenius'', nor [[Literature/EvilGeniusTrilogy the books]] by Catherine Jinks, which involve a SchoolForScheming aimed at creating these.



[[folder: Anime and Manga]]
* Johan Liebert from ''Manga/{{Monster}}''. He's extremely smart, intellectual, and a sociopathic SerialKiller.
* ''Manga/OnePiece'' makes occasional mention of the World Government's top scientist, Dr. Vegapunk. He is one of the most speculated-upon characters in the manga. Apparently, he's an OmnidisciplinaryScientist, having created a cyborg with Devil fruit powers (Kuma), multiple copies of said cyborg armed with laser weaponry (the Pacifista), catalogued all known devil fruits, revolutionized the power of the sea as uses of Seastone, and figured out a way for inanimate objects to "eat" Devil fruits. For all this, events around the TimeSkip have alluded to Vegapunk being morally ambiguous, and truly any statement of him being "evil" before then was an assumption. [[spoiler: During the TimeSkip, Franky, having burned off all of his skin, rebuilds his body using Vegapunk's technology]]
** To a lesser extent, [[PsychoForHire Gecko Moria's]] right hand man Dr Hogback, a surgeon of legendary skill who assisted Moria in creating a [[ZombieApocalypse zombie army]].
** Vegapunk's rival, Ceasar Clown, is stated by all parties except his underlings as being evil [[spoiler: and then, only because he shifted the blame for his own atrocities onto Vegapunk]], and was arrested by the world government for sabotaging the science team's human experimentation. His arc shows [[BadBoss that]] [[ManipulativeBastard his reputation]] [[AxCrazy is]] [[LaughablyEvil fully]] [[WouldHurtAChild deserved]]
* Uno of ''Franchise/LyricalNanoha'', who is known as the second brain of [[BigBad Jail Scaglietti]] and acts as MissionControl for the [[QuirkyMinibossSquad Numbers]]. Jail himself easily qualifies as BigBad variation.
* John Smith (no, that's ''not'' an alias) from ''Anime/MaiOtome'', with a dash of MadScientist thrown in.
* Solf J. Kimblee from ''Manga/FullmetalAlchemist''. On top of being a standout in a WorldOfBadass, he's as sharp and devious as they come with photographic memory to boot.
* Shader in ''Manga/ChronoCrusade'' serves as the Sinner's main techie. Aion, the BigBad, has elements as this as well, considering he's a bit of [[TheChessmaster a chessmaster]].
* Herr Doktor in ''Manga/{{Hellsing}}'' is the evil genius for Millennium.
* Hakase in ''Manga/MahouSenseiNegima'' probably would have played this part in Chao's evil army if not for the fact that Chao was ''also'' an Evil Genius of an even higher degree. Still, this was essentially her role in that she was the one overseeing the ritual to remove the world's WeirdnessCensor, not actually taking part in the battle
* ''Manga/{{Naruto}}'' has Orochimaru with Sasori for the Akatsuki after Pain's death Tobi the BigBad takes the role until Kabuto joins and is this for Tobi's akatsuk army.
** Whether either of them actually [[AntiVillain qualifies as]] [[GrayAndGrayMorality evil]] is up for debate.
* Professor Nanba ([[AccidentalMisnaming or is it Kimba?]]) is the Evil Genius who gives [[QuirkyMinibossSquad Butch and Cassidy]] orders in ''Anime/{{Pokemon}}''.
* Kururu from ''Manga/SgtFrog'' lives and breathes Evil Genius, though [[TokenEvilTeammate he's technically with]] [[VillainProtagonist the good guys]].
* Sosuke Aizen from ''Manga/{{Bleach}}'' combines this with BigBad (as well as ManipulativeBastard, MagnificentBastard, TheChessmaster, etc).
** Also in ''Manga/{{Bleach}}'', R&D Head and 12th Company Captain Mayuri Kurotsuchi is the Evil Genius [[TokenEvilTeammate for the entire Soul Society]] along with being the MadScientist. His Arrancar counterpart, SmugSnake 8th Espada Sayzel Apporro Granz is more or less the same, but with the addition of {{Squick}}y sexual imagery and SissyVillain to the list. And then there's the AntiVillain 1st Espada Coyote Stark, who's a BrilliantButLazy AwesomenessByAnalysis type.
* Koshiro Kokujo of ''Anime/DuelMasters'' was this, or so he said.
--> '''Kokujo''': I know everything!\\
'''Shobu''': How's that?\\
'''Kokujo''': Because I'm an evil genius!
* The Doctor from ''Manga/BlackCat'' is an EvilutionaryBiologist and psychopath who serves as [[TheBigBad Creed's]] go to guy for technology and weapons, while doing double duty as a villainous example of TheMedic.
* Hoji from ''Manga/RurouniKenshin'' is [[BigBad Shishio's]] [[TheStrategist Strategist]], logistician, and all around PsychoSupporter.
* [[TheDragon Cassius]] from ''Manga/KimbaTheWhiteLion'' tends to make the {{Evil Plan}}s for his boss [[EvilOverlord Claw]].
* In ''Anime/MobileSuitGundamSEED'', Nicol, TheDarkChick, also took on this role to the {{Antivillain}}ous Le Creuset team, relying on stealth, caution and an InvisibilityCloak. It only made him more of an outcast on a team of guys who wouldn't know subtle if it bit them in the ass. One could argue that BigBad Rau Le Creuset also plays this role.
** Amongst the Earth Forces high command, [[ObstructiveBureaucrat General Staff officer]] [[GeneralRipper Captain William Sutherland]] did double-duty as TheDragon and Evil Genius, serving as Muruta Azrael's NumberTwo ''and'' TheStrategist. Every morally reprehensible plan you see the Earth Forces execute? This guy's idea.
* As the OnlySaneMan among a group of AxeCrazy {{Tykebomb}}s, Sting Oakley fullfills this role for ''Anime/MobileSuitGundamSEEDDestiny'''s [[SuperSoldier Extended]], since he's the only one with any common sense. He leads the group in [[TheDragon Neo's]] absence, does his best to keep [[TheBrute Auel]] and [[DarkChick Stella]] out of trouble, and is [[KnowWhenToFoldEm the one who usually has to call retreat]]. The ZAFT team lacked a specific Evil Genius; fortunately, BigBad Gilbert Durandal was able to handle both positions.
* In ''Anime/MobileSuitGundamWing'', [[AxeCrazy Chief Engineer]] [[MadScientist Tsubarov]] was this to the Romefeller Foundation. A brilliant technician, he invented the remote-controlled Mobile Dolls whose useage consumes much of the subsequent plot; he's also one of the few men at the OZ base who realises that using the captive Gundam pilots as test subjects might be a bad idea. Curiously, he had a personality that one would more typically associate with TheBrute being a thuggish {{Jerkass}} and SmugSnake who loathed pacifism, had NoIndoorVoice, dealt with problems by applying as much brute force as possible, and went out in the midst of a truly epic VillainousBreakdown, ranting about how he was invincible.
* The ''original'' Evil Genius in a Franchise/{{Gundam}} series was actually [[MagnificentBitch Princess Kycilia Zabi.]] She's one of the Principality of Zeon's better strategists and admirals, is in charge of Newtype research and the new mobile suits and mobile armours that come with it, ''and'' on top of it she's a LadyOfWar who's not afraid of getting her hands dirty if she has to.
* Alister/Amalda was this to Dartz's group of henchmen in ''Anime/YuGiOh''. Nesbitt plays this role to the Big 5, being their tech guy and weapons expert; oddly enough, he's perhaps their poorest duelist.
* ''Manga/{{Eyeshield 21}}'': JerkJock Clifford D. Louis is TheStrategist and Evil Genius of the American Pentagram, in addition to being a member of the BigBadDuumvirate alongside Mr. Don. Youichi Hiruma and Reiji Marco could also be considered evil geniuses, with the former being an {{Antihero}}ic GuileHero and the latter his EvilCounterpart and the BigBad of the Kantou Regionals Arc.
* ''Manga/FairyTail'' gives a few examples.
** Fried Justine pulls double duty, being both this and TheDragon.
** Brain, leader of Oracion Seis, is a full blown MadScientist who is also the BigBad of his arc. [[spoiler: Only he's not really the BigBad, that's his SuperpoweredEvilSide, Zero.]]
** Byro from the Edolas arc fights using potions and other chemicals, and has also created Edolas's equivalent of a WaveMotionGun.
** Samuel from the Zentopia arc cements his status as this with AwesomenessByAnalysis.
** Seilah of Tatarus is in charge of the technology that gives her guildmates ResurrectiveImmortality.

[[folder: Comic Books]]
* In ''Franchise/{{Superman}}'' comics, Lex Luthor was originally this trope with shades of BigBad. ComicBook/PostCrisis the roles were inverted: Luthor was a BigBad with shades of Evil Genius. He also has some other Evil Geniuses on his payroll.
** The Intergang mob had Dabney Donovan as their Evil Genius.
** The Cyborg Superman builds all of the technology used by the [[Franchise/GreenLantern Sinestro Corps]], including the Manhunter robots who recharge yellow rings and the space station they used as a base.
* [[ComicBook/{{Shazam}} Captain Marvel]] a.k.a. SHAZAM's enemy Dr Sivana is another early textbook example of this. He's the guy in the picture above. When he's in teams, he finds himself here.
* ComicBook/CaptainAmerica foe ComicBook/RedSkull is often depicted this way.
* ComicBook/SpiderMan has described ComicBook/DoctorOctopus as one, and seeing as Ock is a brilliant engineer and inventor, he fits, although unlike most, whenever he's part of a group, he's usually the one in charge.
* TeenageMutantNinjaTurtles baddie Baxter Stockman can be viewed as a kind-of failed evil genius in most versions.
* Darth Maladi from ComicBook/StarWarsLegacy is both a [[MadScientist Sith alchemist]] and the head of Sith Intelligence. She's generally portrayed as one of the most cunning Sith characters in the comic, but seems to enjoy her schemes and experiments more [[ForTheEvulz for their own sake]] than from the hope of doing anything constructive with them.
** Also Vul Isen as he is believed to be a scientist. He never accepts anything without a proof.
* In ''ComicBook/AllFallDown'', IQ is VERY bitter about not being one of these anymore.
%% * In ''ComicBook/UltimateFantasticFour'', there is Rhona Burchill, the Thinker, who is physically deformed but has a genius-level intellect.
* ''Franchise/{{Batman}}'' has The Riddler, who provides to be the biggest mental challenge out of his RoguesGallery.

[[folder:Films -- Animated]]
* Lord Shen from ''WesternAnimation/KungFuPanda2'' doubles as this and the BigBad.
* Jumba Jookiba from ''Franchise/LiloAndStitch'' likes to [[CardCarryingVillain call himself this]], although the "evil" part is eventually subverted. He was even ''smarter'' as an "evil genius child prodigy!" And ''adorable''.
-->'''Baby!Jumba:''' "Haha! Ewil! Ewil!"

[[folder:Films -- Live-Action]]
* A very frequent minion type in the ''Film/JamesBond'' series.
** ''Film/DrNo'': Dent to Dr. No. Dr. No himself is this to [[BiggerBad Blofeld]].
** ''Film/FromRussiaWithLove'': Kronsteen to Klebb
** ''Film/{{Goldfinger}}'': Ling to Goldfinger
** ''Film/{{Thunderball}}'': Kutze to Largo
** Osato (''Film/YouOnlyLiveTwice'') and later Metz (''Film/DiamondsAreForever'') to Blofeld
** ''Film/TheManWithTheGoldenGun'': Hai Fat to Scaramanga
** ''Film/AViewToAKill'': Mortner to Zorin
** ''Film/LicenceToKill'': Krest to Sanchez
** ''Film/GoldenEye'': Boris to Trevelyan
** ''Film/TomorrowNeverDies'': Gupta to Carver
** ''Film/TheWorldIsNotEnough'': Arkov to Renard
** ''Film/DieAnotherDay'': Popov to Graves
** There are occasional subversions: Whitaker, Khan, Kananga, Drax, Kristatos, and Le Chiffre were all the "main brains" in their operations as well as the leaders while Stromberg has kills both of his early in the film to cover his tracks.
* Theo to Hans Gruber in the first ''Film/DieHard''.
* ''Franchise/StarWars'':
** Grand Moff Tarkin from ''Film/ANewHope'' could count, as he has the Death Star, and is a strategist with his own doctrine.
** And in the prequel trilogy era, Nute Gunray and the Separatist Council fit the role as they are the brain of everything, and later [[YouHaveOutlivedYourUsefulness when they are no longer needed,]] they are killed by their [[BadBoss boss]].
** Palpatine himself has traits of this.
* James [=McCullen=] and the Doctor in ''Film/GIJoeTheRiseOfCobra''. [[spoiler: At the end of the film, the Doctor becomes the BigBad, Cobra Commander, and turns [=McCullen=] into Destro.]]
* ''Film/MysteryMen'''s Casanova Frankenstein is an evil Disco genius. Even his archnemesis asks him for help with his quips. He wears a set of golden finger cuffs that carry sonic rays and hyper-lasers, and a pair of slippers that emit poison gas. And that's just what his enemy knows he's ''wearing'' while he just sits around in his dressing gown.
* ''Film/PiratesOfTheCaribbeanOnStrangerTides'', has Quartermaster, a zombie who can always predict a future, and he is the one who guides [[BigBad Blackbeard]] to the Fountain of Youth.
* ''Film/TheDollarsTrilogy''
** In ''Film/AFistfulOfDollars'', Ramon Rojo is a non-stereotypical example. In a family of archetypal Mexican {{bandito}}s, Ramon is TheStrategist, concocting the plan to steal the gold from under the Mexican army's nose, and orchestrating the eventual massacre of the rival Baxter family. He's also the only one to see through Joe, and keeps a wary eye on him throughout the film, eventually deducing that he is the traitor in their ranks.
** in ''Film/ForAFewDollarsMore'', El Indio is a similar case.
* Soundwave plays the Evil Genius role in ''Film/TransformersRevengeOfTheFallen'' and ''Film/TransformersDarkOfTheMoon'' as an intelligence specialist as well as overseeing a decades-long scheme in the latter movie.
* Pete from ''[[Film/{{Neighbors2014}} Neighbors]]''.
* ''Film/XMenFilmSeries''
** Magneto, with truly amazing schemes. In ''Film/XMenDaysOfFuturePast'', [[spoiler:he was able to steal a file containing the details of the Sentinels, after reading it over he was somehow able to reprogram them while inserting metal tracks within the bodies.]]
** Toad from ''Film/XMen1''. He's even seen tampering with Magneto's machine.
* In ''Film/ThePinkPantherStrikesAgain'', Professor Fassbender is a total subversion. [[TokenGoodTeammate A full-blown good guy]] [[KidnappedScientist who was kidnapped]] along with his daughter Margo by henchmen of [[BigBad former Chief Inspector Dreyfus]], he was forced to build a doomsday machine and be part of Dreyfus' criminal organization against his will [[IHaveYourWife when Dreyfus used the professor's daughter as leverage.]] He still hated having to work for a madman bent on world domination. [[spoiler: And probably things didn't get better after Dreyfus' defeat as he might have had to face charges for crimes committed against his will (like the destruction of the United Nations building), especially with Dreyfus himself too destroyed to be arrested [[CanonDiscontinuity (assuming the events of the later sequels never happened, including Dreyfus']] UnexplainedRecovery).]]
* ''Film/WhiteHouseDown'' has a classical example in Skip Tyler, a computer hacker working for the White Supremacist militia, who spends most of the film in the computer room while listening [[WickedCultured to classical music]]. In the end, [[spoiler: he gets [[HoistByHisOwnPetard killed by one of his own traps]].]]
* ''Film/TheHungerGames'': The unnamed male tribute from District 3 to the the Career Tributes' group.
* Hannibal Lecter in ''Film/TheSilenceOfTheLambs'' is probably the most famous example of this trope.

[[folder: Literature]]
* [[BigBad Lord Voldemort]] from ''Literature/HarryPotter''. He discovered and implemented the Horcrux system himself. Though he does carry the VillainBall occasionally.
** [[HypercompetentSidekick Barty Crouch Jr.]] is a better example. He replaces a teacher, kills his father, and lures Harry away from potential protectors, and no one realizes until nearly the last moment what he's up to.
* Professor Moriarty, the ArchEnemy of Literature/SherlockHolmes, is described [[WorthyOpponent by Holmes himself ]] as "a genius, a philosopher, an abstract thinker." Moriarty uses his brilliant mind to run his criminal organization,and, unlike many other evil geniuses, he is clearly [[BigBad the boss]].
* In ''Literature/TheElenium'', by Creator/DavidEddings, Krager is this to [[BigBadWannabe Annias]] and [[DragonInChief Martel]]. Annias [[SinisterMinister himself is this]] to [[GodOfEvil Azash]].
** Its sequel, ''Literature/TheTamuli'', gives us [[EvilSorcerer Zalasta]].
* The FiveBadBand in Eddings' ''Literature/TheRedemptionOfAlthalus'' has Argan, a SmugSnake and SinisterMinister who does most of [[BigBad Daeva's]] talking for him, and has a distinctive rivalry with [[TheDragon Ghend]].
* In ''Literature/TheWitcher'', we have Vilgefortz. He is easily the most smart and powerful wizard in the North, and he let it get into his head.
* Tyrion Lannister from ''Literature/ASongOfIceAndFire'', an educated, smart, and calculating dwarf sort of qualifies. However, he wasn't really an ally of House Lannister and he was enemies with [[AbusiveParents Tywin]]. He embodies this trope in his own organization, in which he is also the BigBad. He isn't really that evil though.
** Also, from the group of Brave Companions we have [[MadScientist Qyburn]] and [[SinisterMinister Septon Utt]].
* The ''Literature/ArtemisFowl'' series is full of these, which makes sense, since the protagonist himself is a TeenGenius, and that requires antagonists to match. We have Artemis himself in book 1 (in his status as VillainProtagonist), Opal Koboi in book 2, Jon Spiro in book 3, Opal Koboi ''again'' in book 4, Minerva in book 5, Opal Koboi ''AGAIN'' in book 6. [[spoiler:Turnball Root in book 7, and Opal yet AGAIN in book 8.]]
* ''ComicBook/TransformersTransTech'' Shockwave, master of PlayingWithSyringes, is a self-proclaimed "[[InsistentTerminology morally ambiguous]]" genius.
* The Franchise/StarWarsExpandedUniverse gives us Bevel Lemelisk, chief designer of the Death Star, although the actual designers were superintelligent alien children whose planet was being held hostage.
* Literature/TrappedOnDraconica: Lucia's the one with the magical know-how for the evil beasts and teleportation spells and other magic to power [[EvilOverlord Gothon's]] army.
* Several members of [[QuirkyMinibossSquad the Forsaken]] in ''Literature/TheWheelOfTime'', including [[TheAntichrist Ishamael]] (specializes in philosophy, theology, and metaphysics), [[TheVamp Graendal]] (specializes in personal manipulation) and [[FourStarBadass Demandred]] (specializes in millitary strategy).
* The main character of ''Literature/PleaseDontTellMyParentsImASupervillain'' is a MadScientist who comes up with both most of the technology and most of the plans her team uses.
* In Creator/AgathaChristie's story "[[Literature/TheMysteriousMrQuin The Face of Helen]]", the villain is a brilliant chemist who specialized in poison gas during World War I, and attempts to murder the object of his unrequited love with an elaborate death trap involving a glass sphere full of gas and a GlassShatteringSound.
* In the ''Literature/MalazanBookOfTheFallen'', Iskaral Pust's competence is the only reason Shadowthrone keeps him around. His results reinforce this decision: if something needs to be done, Pust will somehow manage to do it, obstacles notwithstanding. He even manages to become [[spoiler:The Magus of High House Shadow]], personally appointed to the task by Shadowthrone himself, by merit alone.

[[folder: Live Action TV]]
* ''Series/GameOfThrones'': Even by the high standards of Westeros' top schemers, Tywin is regarded as TheAce. Littlefinger, Varys and Olenna Tyrell all have high respect for his intelligence and ruthlessness. His son Tyrion even allows that "father has a good mind for strategy"
* Most incarnations of ''Franchise/PowerRangers'' and ''Franchise/SuperSentai'' have one of these among the villains, with responsibilities commonly including mass-producing Mooks and the MonsterOfTheWeek, [[MakeMyMonsterGrow making monsters grow]], and generally being the one who knows the most about the finer points of the magic/technology of the season. In ''Franchise/PowerRangers'', the first and probably the most iconic among fans was [[Series/MightyMorphinPowerRangers Finister]], the series' first monster maker.
* ''Series/{{Smallville}}'' had plenty of {{Evil Genius}}es, with Lionel Luthor, ComicBook/LexLuthor, ComicBook/{{Brainiac}}, and Winslow "The Toyman" Schott running around. One interesting example was [[TheBaroness Tess Mercer]], who started out as a villain, but eventually pulled a HeelFaceTurn. She became one of two [[TheSmartGuy Smart Guys]] on the heroic side, but still in traditionally [[DarkIsNotEvil evil]] areas, being TheChessmaster, a ManipulativeBastard, and TheCracker to [[OmnidisciplinaryScientist Emil Hamilton's]] [[TheMedic Medic]] and GadgeteerGenius.
* Giller from ''Series/LegendOfTheSeeker'' is both MadScientist and EvilSorcerer; the two most typical archtypes that fall under this trope.
* Elizabeth from ''Series/WickedScience'' becomes a genius and she uses her new intelligence as a way to try to get money, fame and Toby's affections. The evil part is that she has little morals when it comes to use her inventions, including using a teleporter to sneak in Toby's laboratory so her goon can destroy/steal/sabotage whatever Toby is creating in the episode, or trapping him in a GroundhogDayLoop so he accepts the new universe in which he's trapped, where they are a couple and his friends hate him.
* Depending on whether you see them as {{Antihero}}es or {{Antivillain}}s, Hardison of Series/{{Leverage}} Consulting & Associates is either TheSmartGuy or Evil Genius. His EvilCounterpart, Colin "Chaos" Mason is a non-ambiguous example being an InsufferableGenius and {{Jerkass}} extraordinaire who seems to view committing crimes as a way to stroke his own ego, and constantly betrays his own allies.
* ''Series/{{Revenge}}'': If you go by AlternateCharacterInterpretation, Mason Treadwell seems to take this role later in the first season, although he isn't fully aware of his role in Emily's scheming.
* ''Series/BuffyTheVampireSlayer & Series/{{Angel}}'':
** Pretty much all of the [[BigBad big bads]] both the Scoobies and Angel Investigations go up against - though definitely except [[DumbBlond Glory]]. Much straighter variations though are Warren Mears and Angelus. While both are [[ManipulativeBastard Manipulative Bastards]] Warren is a more straight-up MadScientist, while Angelus is TheChessmaster.
** Toru especially - he builds a device capable of projecting a hologram, a giant Mecha-Dawn, and a device capable of casting a spell worldwide to {{Depower}} the Slayers.
* ''Series/BreakingBad'' is a {{Deconstruction}} of this in a more realistic setting.
* The campy 60's ''Series/{{Batman}}'' series had ''lots'' of villains who were {{Canon Foreigner}}s but one of the few who was entertaining enough to make return appearances was the Evil Genius Egghead, played by Vincent Price (who often commented publically how much he enjoyed playing the role).
* ''Series/DoctorWho'': Davros, creator of the Daleks. Though crippled with only one working arm, he created the most dangerous life form the universe has ever seen and set them on a path of [[OmnicidalManiac genocide against all other forms of life in existence]]. His intellect is so great that the Daleks often will refuse to kill him, despite him being an "inferior" creature by their doctrine, simply because his intelligence is too useful to them. Even the Doctor readily admits Davros' genius, and he is not one inclined to praise other's mental capabilities (at least not without stating [[InsufferableGenius how much smarter he is]]). As for why he's doing any of this? If the Daleks win, and all life is wiped out save for them... it would be ''his'' hand that set it all in motion. He would be the one who killed the universe.
-->'''Davros''': That power would set me above the gods! And through the Daleks, I shall have that power!

[[folder: Mythology]]
* Shakuni, EvilUncle of EvilPrince Duryodhana in the Literature/{{Mahabharata}}.

[[folder:Professional Wrestling]]
* Manager turned wrestler turned manager "{{Pretty Boy}}" Wrestling/BobbyHeenan, while perhaps not thinking of himself as "evil", is {{insufferable|genius}} on anything he believes to be correct and almost completely immoral. In Wrestling/{{WCW}} it turned out he didn't approve of the Wrestling/{{new World order}} though but true to the trope, was the only one to suggest Wrestling/HulkHogan ''might'' be a part of it, though he had been critical of Hogan since the Wrestling/{{A|mericanWrestlingAssociation}}WA. Another irony is that Heenan had to drop out of school as a child due to a lack of money got his first managerial role after carrying wrestler bags to support his family. His loud mouth "Brain" persona may have been a front.
* Lightning Hernandez was described as "an evil genius" on the Dominican Republic television program "International Wrestling" and was implied to be [[EvilIsOneBigHappyFamily directing all the bad wrestlers and managers]](but then, Jack Veneno was implied to be behind all the {{tecnico}}s).
* In the remnants of the Wrestling/NationalWrestlingAlliance, "The Mastermind" Dave [=DuPont=] is an {{expy}} of Heenan, shifting between wrestler and manager.[[/folder]]

[[folder: Tabletop Games]]
* In ''TabletopGame/MagicTheGathering'', Yawgmoth is this and the BigBad, but in New Phyrexia, with its five-color theme, Jin-Gitaxis, the blue praetor, takes this role.
* ''TabletopGame/Warhammer40000'' has Fabius Bile, former Apothecary of the Emperor's Children. Unlike most examples, he's very much imposing, being seven feet tall and wearing PowerArmor, makes the TrainingFromHell and surgical procedures to make Chaos SpaceMarines even more restrictive, and has even declared that the four gods of Chaos have nothing left to offer him.

[[folder: Video Games]]
%%* [[MadScientist Professor Hojo]] in ''VideoGame/FinalFantasyVII'' is this to President Shinra.
* ''VideoGame/{{Wild ARMs 1}}'' had the MadScientist demon Alhazad. ''VideoGame/{{Wild ARMs 4}}'' had part scientist, part strategist Augst.
* Albert [[TheStrategist Silverberg]] of ''VideoGame/SuikodenIII''.
* [[spoiler:Izuka]] in [[VideoGame/FireEmblemTellius Fire Emblem 10]] (Radiant Dawn).
* In ''VideoGame/AdvanceWars Black Hole Rising'' and ''Dual Strike'', PerkyGoth Lash provides the bad guys with all of their advanced technology.
** Caulder/Dr Stolos in ''Days of Ruin'', who eventually becomes the BigBad.
* Hazama/Terumi Yuuki from ''VideoGame/BlazBlue''. The most dangerous thing about his genius, however, isn't his trancendental knowledge of alchemy, which allowed him to create the titular [[ArtifactOfDoom Blaz Blue]], the [[{{Orochi}} Black Beast]], [[EldritchAbomination Arakune]] and some other unpleasant things, but rather his tactical genius, which, so far, has allowed him to [[DefeatingTheUndefeatable outmaneuver an omniscient supercomputer with three minds]] (although he got help from the guy below). Then again, Hazama himself would qualify in any positions given in the FiveBadBand.
** There must also be a mention of Relius Clover, a brilliant researcher who sought only perfection and has performed horrendous experiments and {{plan}}s, as shown during his EX Story where he played Sector Seven and Kokonoe for chumps. Though he had less time to shine than Hazama it could be said that Relius is an even purer example of this trope: We learn that much of Hazama's apparent genius comes from his ability to [[RippleProofMemory remember previous timeloops]] and he loses this edge once the loops stop, while Relius' defining characteristics are his [[MadScientist intellectual brilliance]], [[ForScience scientific curiosity]], and [[TheSociopath lack of concern for the fallout]].
* In ''VideoGame/KingdomHeartsChainOfMemories'', Vexen, a sterotypical MadScientist fits for this role. Then, in ''VideoGame/KingdomHeartsII'' we have Luxord, a strategic gambler.
** In the original ''VideoGame/KingdomHearts'', [[Disney/{{Aladdin}} Jafar]] definately owned this role.
* Galak Fyyar from ''VideoGame/JediOutcast''.
* In ''VideoGame/EpicMickey'', WesternAnimation/TheMadDoctor appears to be TheDragon for the [[BlobMonster Shadow Blot]]. Later however, it is revealed that the Shadow Blot himself is TheDragon for the real Shadow Blot (the other Blot revealed to be just a disconnected part). This moves our MadScientist, to the position of this trope.
* Agnus fills this position for [[SinisterMinister Sanctus]] in ''VideoGame/DevilMayCry 4''. Although one could equally argue that he's TheDragon, as he appears to be the only member of the Order beyond Sanctus who truly understands what's going on, killing him is the last thing that needs to be done before the final confrontation, and the nominal Dragon is a HonorBeforeReason HeroAntagonist.
* The player character in ''VideoGame/EvilGenius'', CaptainObvious.
* Murzhor in ''VideoGame/HerosRealm''. He's got a bit of MasterofIllusion to boot.
* Dr. Elvin Atombender from the ''VideoGame/ImpossibleMission'' games is a genius computer programmer and former university professor. Although he has been unstable his whole life, he officially became criminally insane when a power failure caused the deletion of an artificial intelligence program that he had nearly finished. The player must stop him from hacking into the defense networks of the world's superpowers and starting a nuclear holocaust.
* Dr. Vu in the ''VideoGame/SimCity'' and ''VideoGame/TheSims'' series.
* ''VideoGame/LunarTheSilverStar'' has Taben, who creates a mechanical army for the Vile Tribe and Magic Emperor.
* ''VideoGame/{{Strider}}'' has Herzog Schlange in ''Strider 2'' and Professor Schlange in the HD ''Strider'' remake. Both are (mad) geniuses in charge of building the bizarre mechanical monsters and weapons used by the Grandmaster's army. In the latter's case, he's charged over the Grandmaster's entire research complex, and seems to be only below [[TheDragon Juroung]] in terms of ranks. Though this didn't save him from being [[OffingTheAnnoyance offed]] in the end.
** The Grandmaster himself has shades of this, though he leans more toward genetic engineering instead of robotics, in his quest to create a new race to which replace "the sons of old gods" and rule Earth as a true God.
* Dr. Kimaira in ''VideoGame/{{Tenchu}}: Wrath of Heaven'', notably because he's a MadScientist who creates ''wooden automatons with hidden machine-guns'' in '''medieval Japan'''.
* Crow from ''VideoGame/{{Nefarious}}'', who doubles as the playable VillainProtagonist.
* Though most of [[NebulousEvilOrganization Umbrella's]] scientists in ''VideoGame/ResidentEvil'' counted as this, the most developed and well-known of them all was William Birkin. Not only was he one of the few scientists to ''not'' be completely unstable and insane, as he managed to have a (relatively) normal family life with a wife and child, but he was also responsible for creating both the T and G viruses which drove the entire plot up to ''VideoGame/ResidentEvil4''. Albert Wesker's also pretty darned intelligent too, though his skills are more of the ChessMaster / MagnificentBastard variety rather than lab work[[note]]He ''did'' work in the laboratory, though what he created (if anything) hasn't been revealed[[/note]].
* ''VideoGame/AssassinsCreedIVBlackFlag'' has Julien du Casse playing this role for the [[AncientConspiracy Templars]], serving as the Order's main supplier of weaponry and ammunition.
* [[BigBad Dr. Eggman]] from ''Franchise/SonicTheHedgehog''.

* In [=ClockUp=]'s ''Euphoria'', [[spoiler:this is what Kanae turns out to be, [[BitchInSheepsClothing among]] [[MadScientist other]] [[BettyAndVeronicaSwitch things.]]]]

[[folder: Webcomics]]
* ''Webcomic/FollyAndInnovation'' uses this trope [[http://follyandinnovation.com/2010/08/facebook-a-devious-scheme-nah-theres-no-way/ here]] speculating Website/{{Facebook}}'s origins
* ''Webcomic/GirlGenius'' is crawling with them. Even some protagonists, on a few occasions.
* ''Webccomic/DrNonami'' has Dr. Mechano, an eccentric yet dangerous evil mastermind.
* ''Webcomic/TheOrderOfTheStick'': General Tarquin is sort of this to his own team of aging adventurers ([[https://twitter.com/richburlew/status/435651746556149760 nicknamed]] "The Vector Legion"). According to [[WordOfGod Word of the Giant]], the other team members see him as the 'ideas guy', who comes up with plans that a group of very powerful evil adventurers [[PragmaticVillainy can all join in on for their mutual benefit without backstabbing each other]]. Tarquin himself thinks this makes him their leader. The others don't, but think he's useful enough not to press the issue. They also have two actual evil geniuses who takes care of all the actual planning and minutiae.
* ''Webcomic/WaywardSons'': Doctor Chu, who very much enjoys performing torturous experiments on live subjects.
* Elia of ''Webcomic/TrueVillains'' takes over most Evil Genius duties. Just replace technology with magic.

[[folder: Web Original]]
* ''Machinima/ArbyNTheChief''
** Brian in Season 5, on account of being an OMN Administrator, though he's [[AntiVillain not really evil]] and he's only an antagonist because he's associated with [[BigBad Trent Donnovich]].
** Justin "[=SniperDeathAngel00=]" in Season 6 plays this more straight, being the creator of the Fragban hacks used by Chaos Theosis and the Underground Hackers.
** Season 7 has Colin Hunt, the inventor of the Fragban 2.0 hacks.
* [[PuttingOnTheReich Führer]] [[GodSaveUsFromTheQueen Katrina Seran]] from v2 of ''Roleplay/OpenBlue'' was a [[TheStrategist strategist]], ChessMaster, and [[TheCaptain ship captain]] who became ruler of her country at the [[ImprobableAge age of 20]], possibly due to her own machinations.
* Belial in ''Literature/TheSalvationWar'' is one of these, and is the one Baldrick who actually inflicts serious damage on the humans.
* Music/DoctorSteel. Naturally.
* The ''Roleplay/GlobalGuardiansPBEMUniverse'' has several. Doctor Simian, the Evil Mastermind, Brainchild, and Baron Malthus are the most notable examples.
* In the Literature/WhateleyUniverse, there are lots of MadScientist types. The ones who work for other supervillains tend to be characters like Chessmaster or Nimbus. The two of them nearly destroyed [[SuperheroSchool Whateley Academy]] on Halloween.
* Dr. Spectre from ''Blog/TheTyrannosaurChronicles''.
* Tattletale fills this role in ''Literature/{{Worm}}'', though it should be noted that she's not supersmart, instead her power makes her a master of the SherlockScan, which she uses to great effect in social, combat, and political situations.

[[folder: Western Animation]]
* Tarantulas of ''WesternAnimation/BeastWars'' is this all over the place.
* ''WesternAnimation/DarkwingDuck'' gives as Bushroot, a member of the Fearsome Five group, which makes perfect example of FiveBadBand.
* Mandark from ''WesternAnimation/DextersLaboratory''.
* ''WesternAnimation/ExoSquad'' has a ''race'' of Evil Geniuses called Neo Megas.
* Heloise on ''WesternAnimation/JimmyTwoShoes'', [[ChaoticNeutral whenever it suits her]] to work for Lucius.
* Wraith in ''WesternAnimation/TheMightyDucks'', distinguished for mainly using [[FunctionalMagic magic]] when the BigBad [[MagicVersusScience prefers technology]].
* As per usual, Doctor Octopus is a super villain who is also a brilliant engineer and inventor. He goes the extra mile by having "Evil Genius" printed on the side of his coffee mug in ''WesternAnimation/TheSpectacularSpiderMan''. Although he is subordinate to no one.
* Alistair Smythe works as an evil genius for the Kingpin in ''WesternAnimation/SpiderManTheAnimatedSeries''
* Two examples from ''WesternAnimation/TeenTitans''- Gizmo is the resident GadgeteerGenius of [[QuirkyMinibossSquad the HIVE Five]], though his utter lack of people skills keeps him from rising any higher, while [[BrainInAJar the Brain]] pulls double duty as Evil Genius ''and'' BigBad of the Brotherhood of Evil.
* Cartman himself from ''WesternAnimation/SouthPark'' is this in "Scott Tenorman Must Die", [[spoiler:where he tricked Scott Tenorman into eating his parents after calculating a painstaking amount of detail, up to Cartman's friends betraying him]].
* ''WesternAnimation/XiaolinShowdown'': Though he doesn't fit all of the character tropes, Jack Spicer (himself a self-proclaimed Evil Genius, with emphasis on ''self-proclaimed'') calls Chase Young "the greatest Evil Genius in the world" and there's no denying that it's true. As for Jack himself - there's no denying that he ''is'' a genius, it's just whether or not he's actually, you know, ''evil''.
* In ''WesternAnimation/TheLegendOfKorra,'' both [[GeniusDitz Varrick]] and [[AntagonisticOffspring Baatar Jr.]] (who's also TheDragon and [[DoctorGirlfriend Doctor Boyfriend]]) could be considered this for [[TheConqueror Kuvira]]'s army, being {{Mad Scientist}}s; when Varrick [[HeelFaceTurn defects]], Baatar takes the role full-time. Of course, it's more or less clear Baatar is much better than Varrick, a fact the latter is loathe to put up with.
* In ''WesternAnimation/IronManArmoredAdventures'', there is Rhona Edwin, who was the best student at the Tomorrow Academy before Tony Stark showed up. After becoming convinced that Tony has been cheating, she takes the entire school hostage and forces Tony into a sort of game show from hell to prove his intelligence.
* Dr. Stinger from ''WesternAnimation/SuperDuperSumos'' is an interesting example because, while none of the other villains showed him any respect at all, he was really the only one on the villains' side who ever actually ''did'' anything.
* Doofenshmirtz from ''WesternAnimation/PhineasAndFerb''. A DitzyGenius to be sure, but like the title characters, he's nevertheless smart enough to invent ''anything'' in only a few hours, even to the point of [[BeyondTheImpossible flagrantly defying the laws of physics]].
* Brain in ''WesternAnimation/PinkyAndTheBrain'''... [[DownplayedTrope kinda]]; despite attempting to TakeOverTheWorld every night, he's not really evil.
* ''WesternAnimation/{{Kaeloo}}'': Both [[GadgeteerGenius Mr. Cat]] and [[RobotMaster Olaf]] fit this trope.
