->''"You know what I love about machines? They do what they're told."''
-->-- '''Doctor Ivo "Eggman" Robotnik''', ''Film/SonicTheHedgehog2020''

A scientist who specializes in building or maintaining robots.

If he is a MadScientist, this skill will probably manifest as an ability to effortlessly manufacture MechaMooks in bulk. Robots don't have to be his only area of expertise (as a mad scientist, he's probably also an OmnidisciplinaryScientist), but he's a Robot Master if robot-making is far and away his most commonly displayed skill. For instance, Doctor Doom is a scientist who builds robots periodically, but fellow ''ComicBook/FantasticFour'' enemy the Mad Thinker builds robots virtually every time he appears.

[[SmartPeopleBuildRobots Just building one robot doesn't qualify you for this trope.]] This is for people whose resumés are more than 50% taken up with robot-building or at least robot-fixing.

Not to be confused with the ''VideoGame/MegaManClassic'' Robot Masters, though this trope does apply to their creators.

May or may not overlap with MarionetteMaster. Many [[TheIgor Igors]] qualify, depending on their bosses' area of expertise. Compare with DroneDeployer and TheTurretmaster (for different kind of "robots") and WickedToymaker. If you were looking for a robot that ''is'' a master, see MasterComputer.

[[folder:Anime & Manga]]
* Dr. Gero from ''Anime/DragonBallZ'' made many robots to fight Goku, though some of them are cyborgs (17, 18, and himself) or artificial lifeforms (Cell).
* Dr. Vegapunk of ''Manga/OnePiece''. This may change later on, as he's pretty much stated to have [[OmnidisciplinaryScientist a whole plethora of other accomplishments under his belt]], but his most prominent role in the story thus far is creating a small army of [[MechanicalMonster Pacifistas]] for the World Government.
* Jail Scaglietti from ''Franchise/LyricalNanoha''. He also builds cyborgs.
* Winry of ''Manga/FullmetalAlchemist'' is constantly repairing robotic limbs and such.
* All Incarnations of Dr. Hell from [[Anime/MazingerZ the]] ''[[Anime/{{Mazinkaiser}} Mazinger]]'' [[Anime/ShinMazinger series]] are this to varying degrees.
* Dr. Rotwang from ''Anime/TigerAndBunny''.
* Engineer Sakaki from ''Franchise/{{Patlabor}}''.
* Doctor Tenma and Doctor Ochanomizu from ''Manga/AstroBoy''.
* ''Doll'' by Mitsukazu Mihara is an anthology series about humans interacting with robots, so it's only natural that many of its characters are robot specialists.
* Norman Burg in ''Anime/TheBigO'' knows how to maintain a [[HumongousMecha megadeus]] -- though being an [[LaserGuidedAmnesia amnesiac]] like everyone his age in Paradigm City, he doesn't remember how he learned this skill. He repairs and maintains the Big O for Roger.
* Biko Daitokuji (B-Ko) from ''Anime/ProjectAKo'' is this as Tony Stark levels, a high school student capable of building a new {{Super Robot|Genre}} mecha to battle A-Ko every night.
* Metal Knight, and to a lesser extent Child Emperor, from ''Webcomic/OnePunchMan''.
[[/folder]]

[[folder:Comic Books]]
* Dr. Will Magnus, creator of the ''ComicBook/MetalMen''.
* The Mad Thinker from ''ComicBook/FantasticFour'' is this trope combined with TheChessmaster. His most well-known creation is a [[OrganicTechnology biological robot]] called the Awesome Android.
* The Toyman from ''ComicBook/{{Superman}}'' can build lifelike androids, but prefers to [[WickedToymaker make his killer robots look like toys]].
* ''ComicBook/JusticeLeagueOfAmerica'':
** Dr. T.O. Morrow, creator of ComicBook/RedTornado, Tomorrow Woman, and assorted other bots. They [[AIIsACrapshoot tend to rebel on him]], but since he's evil, that's usually a good thing. Ironically, Morrow has at times expressed pride that he's capable of creating androids so intelligent they're ''capable'' of going against their programming and rebelling against him.
** Professor Ivo built Amazo, a robot capable of [[PowerCopying mimicking his enemies' powers]].
* ''ComicBook/SpiderMan'':
** Spencer Smythe, creator of the Spider-Slayers. After his death, his son, Alistaire Smythe, continued his legacy by building more Spider-Slayers, eventually turning himself into a cyborg.
** Also minor Spidey antagonists Armada and Future Max.
** And minor character Mendel Stromm, who actually calls himself "Robot Master".
* Dr. Abel Stack, who built Aaron Stack the ComicBook/MachineMan. He also helped build all the previous robots in Aaron's series, who all [[MurderousMalfunctioningMachine went mad]]. The reason Aaron turned out all right is that Abel actually [[RoboFamily raised him as a son]]. Of course, [[CharacterizationMarchesOn years later]], [[SufficientlyAdvancedAlien the Celestials]] kidnapped Aaron, causing him to suffer a nervous breakdown and turn into the [[DeadpanSnarker snarky]], [[JerkWithAHeartOfGold endearingly neurotic]] {{Jerkass}} we know from ''ComicBook/{{Nextwave}}'', but that's another story.
* Bolivar Trask, creator of the ComicBook/XMen's robot nemeses, the Sentinels.
* The (possible) {{Trope Namer|s}} from ''ComicBook/TheTransformersMarvel'' is actually an [[InvokedTrope invocation of this trope]]: failing comic-book writer Donny Finkelberg is enlisted by the government to pose as his character "Robot Master" and claim credit for the Transformers' battles, as this was judged [[TheWorldIsNotReady less publicly frightening than an alien civil war]]. HilarityEnsues when the 'cons found out that some dumb squishy was pretending to be their master. In fact, when Megatron awakens, he decides to keep Finkleberg around to continue the charade, since he could make it look like ''all'' robots are under his control, [[HeroWithBadPublicity making it harder for the Autobots to enlist human allies]]. It doesn't ''quite'' work in the long run, since it's kind of hard to explain why one guy would have two sets of robots fighting each other, but it becomes moot when Finkleberg manages to escape.
* ''ComicBook/TheAvengers'': Despite being a robot himself, Ultron would certainly count. He built ComicBook/TheVision, Jocasta, [[Comicbook/{{Runaways}} Victorius]], and Alkhema, as well as countless duplicates of himself -- usually just replacement bodies for when he inevitably gets destroyed at the end of each appearance, but he has built armies of these duplicates on a couple of occasions (with the predictable ConservationOfNinjitsu in full effect). His unique creations have a tendency to rebel against him and become superheroes.
* The Followers of the Light from ''ComicBook/ShogunWarriors'' are aliens who built the titular HumongousMecha to fight [[{{Kaiju}} giant monsters]].
* Tyranik from ''ComicBook/ManTech'' was [[MadScientist driven mad]] by the same [[NeglectfulPrecursors ancient]] "knowledge ray" that taught him about robotics, so he wants to wipe out mankind and replace it with robots.
* The Katayanagi twins from ''ComicBook/ScottPilgrim'', though the building itself happens off-screen. In the comics, anyway; [[Film/ScottPilgrimVsTheWorld the film]] changes them to techno-themed {{Musical Assassin}}s.
* Baxter Stockman from the original ''Franchise/TeenageMutantNinjaTurtles'' comics is a computer expert who builds small "Mouser" robots and uses them to commit crimes.
* ''ComicBook/AstroCity'':
** The first Assemblyman creates rampaging robots for anyone who pays.
** Vivi Vector is a female example who thinks big -- she's spent ''decades'' infiltrating robotics and electronics systems worldwide with her creations.
** Ellie Jennersen was a robotics genius even before she got into college and broadened her expertise. Unfortunately, [[spoiler:her potential was cut short after her roommate {{Mind Rape}}d her and stole her work]].
** Dr. Saturday is a MadScientist who builds giant robots that resemble cartoon characters.
* ''ComicBook/WonderWoman'':
** ''ComicBook/WonderWoman1942'': Byrna Brilyant, the "Snowman", is a brilliant roboticist who used her chemist father's notes to create a weather machine, and her own know how to make a battalion of identical rocket propelled robots and matching PoweredArmor equipped with a FreezeRay.
** Doctor Cyber traditionally has a legion of robotic assassins at her beck and call.

[[folder:Films -- Live-Action]]
* Sebastian in ''Film/BladeRunner''. "They're just toys, really..."
* Nathan from ''Film/ExMachina''.
* ''Franchise/{{Frankenstein}}'': The original DrFrankenstein (named [[DependingOnTheWriter Victor or Henry]]) comes from [[Literature/{{Frankenstein}} the novel]], but the ExpandedUniverse of the movies gives him various relatives and assistants to carry on his legacy.
** ''Film/BrideOfFrankenstein'' introduces his sinister old mentor, Dr. Pretorius.
** ''Film/SonOfFrankenstein'' is ExactlyWhatItSaysOnTheTin with the doctor's son, Wolf Frankenstein, and also introduces the doctor's old assistant, [[TheIgor Ygor]].[[note]]In [[Film/Frankenstein1931 the original film]], the doc's hunchbacked assistant is named Fritz, but Creator/BelaLugosi's character Ygor is the assistant everyone remembers.[[/note]]
** ''Film/TheGhostOfFrankenstein'' introduces the doc's ''other'' son, Ludwig.
** ''Film/FrankensteinMeetsTheWolfMan'' has the generally well-intentioned Dr. Mannering revive the monster. Dr. Frankenstein's beautiful granddaughter Elsa is hanging around, too.
** ''Film/HouseOfFrankenstein'' has Dr. Neimann, implied to be Ygor's brother. And he has his ''own'' [[TheIgor hunchbacked assistant]]!
** ''Film/AbbottAndCostelloMeetFrankenstein'' has the evil Dr. Sandra Mornay revive the Monster (in the service of Count Dracula!).
** ''Film/YoungFrankenstein'' has the doc's descendent, Dr. Frederick [[InsistentTerminology "Frahnkensteen"]], and ''his'' [[TheIgor hunchbacked assistant]], Igor (pronounced EYE-gor).
** And in the AlternateContinuity of the Film/HammerHorror films, Creator/PeterCushing's [[Film/TheCurseOfFrankenstein Dr. Frankenstein]] picks up his own assortment of assistants and sidekicks, including a hunchback played by Roddy [=McDowell=].
** ''Film/JesseJamesMeetsFrankensteinsDaughter'' has (despite the title) Frankenstein's granddaughter Maria as the MadScientist, with her brother Rudolph as her sidekick.
* The ''Franchise/MarvelCinematicUniverse'' version of Tony Stark/Iron Man is portrayed as one. While he prefers to build high-tech armor for himself, he has also programmed complex AIs such as JARVIS and keeps a couple of robotic arms that he built as a kid as his pets. This escalates in ''Film/IronMan3'' when he has JARVIS take control of his extra suits; and then in ''Film/AvengersAgeOfUltron'' he has a set of autonomous "Iron Legion" bots and is a major factor in creating both Ultron and Vision.
* Rotwang from ''Film/{{Metropolis}}'' built an android he intended to turn into the likeness of his lost love, but he gets persuaded to turn her into an evil doppelganger of the saintly Maria instead. It's certainly implied that he would have liked to go back and finally make that android replacement for his lost love, but [[spoiler:he gets killed]].
* Gene Simmons' Dr. Luther from ''Film/{{Runaway}}'' not only builds killer drones, he also sabotages existing household robots so they'll [[TurnedAgainstTheirMasters go berserk]] on command.

* Doctor Impossible, from ''Literature/SoonIWillBeInvincible'', uses a wide variety of tech but specialises in robots and doomsday devices.
* Dr. Emil Lang from ''{{Anime/Robotech}}'' is the world's leading authority on Robotechnology. "Robotechnology" actually refers to ''all'' types of alien-derived technology on Earth, but the most visible type is all the HumongousMecha running around. He eventually succeeds in building a [[RidiculouslyHumanRobot sentient android,]] [[RobotGirl Janice Em.]] Lang is a [[AscendedExtra major character]] in the ''Robotech'' [[ExpandedUniverse novels and comics,]] although he only has a couple of brief cameos in the original TV series.

In the end, we learn that [[spoiler:the real Korby was dead before the start of the episode, and we've been watching his [[RobotMe robot duplicate]] all along]].
* ''Series/StarTrekTheNextGeneration'': Dr. Noonian Soong, creator of Data, Lore, and B4. In ''Series/StarTrekPicard,'' we learn he had a son, Altan, who [[spoiler: helped create a hidden civilization of androids.]]
* Grant Imahara on ''Series/MythBusters'', who created various bots for that show, worked on R2-D2 for the ''Franchise/StarWars'' prequels, and created [[SkeleBot9000 the robot skeleton Geoff Peterson]] for [[Series/TheLateLateShowWithCraigFerguson Craig Ferguson]].
* The MadScientist in "The Cybernauts" episode of ''Series/TheAvengers1960s'' builds two robots, which Steed foils by getting them to destroy each other. In "Return of the Cybernauts", the scientist's assistant is contracted to build [[ExactlyWhatItSaysOnTheTin another one]].
* ''Series/BuffyTheVampireSlayer'': Warren built the April-bot, the Buffy-bot, and finally a robot of himself. Willow shows herself to be quite good at fixing/reprogramming the Buffy-bot when needed. In [[ComicBook/BuffyTheVampireSlayer season 9]], Andrew uses Warren's lab to create another Buffy-bot and switches its consciousness with the real Buffy.
* ''Series/WonderWoman1975'': "The Deadly Toys" features Frank Gorshin of the Riddler fame from ''Series/Batman1966'' as a WickedToymaker. His [[EvilPlan plan]] involves making a robot Wonder Woman to challenge the real Amazon Princess.

** Robot Gladiators supplement. Dr. Anton Wolcott, Chief Roboticist of the Interstellar Gladiator Authority.
** Mechanon probably counts: as a robot, he used automated factories to make improved versions of himself.
* EvilSorcerer variant: Xin, the High King of ancient Thassilon in ''TabletopGame/{{Pathfinder}}'', was enamored with powerful clockwork automatons, and in fact was entombed in a "living" clockwork sarcophagus.
** House Ardoc in the city of Kaer Maga specializes in animating golems and other magical constructs.
* The wizard Trioband in ''TabletopGame/ForgottenRealms'', who created various specialized metal automatons.

* Gaige the Mechromancer and her KillerRobot / ScienceFair project D374-TP a.k.a. "Deathtrap" from ''VideoGame/{{Borderlands 2}}''.
* Robotics Masterminds in ''[[VideoGame/CityOfHeroes City of Heroes/Villains]]'' are playable robot masters.
* Dr. Proton, in ''VideoGame/DukeNukemI'', took over an entire city with the [=TechBots=] he'd built, not to mention the moon base (in Episode 2) and a city in the far-flung future (in Episode 3). This aspect was very much downplayed by the time of his appearance [[VideoGame/DukeNukemForever the 2011 game]]'s DLC, "The Doctor Who Cloned Me", though [[WhatCouldHaveBeen the 2001 version]] might've seen him play a larger role, Robot Master status included.
** Mech Morphix, the Dr. Proton {{Expy}} in ''VideoGame/DukeNukemManhattanProject'', could also qualify, though his army had fewer varieties of robot. Morphix had been intended to ''be'' Dr. Proton, but [[WhatCouldHaveBeen Proton was still in line to be the villain in ''Forever'' at the time]].
* ''Franchise/TheElderScrolls''
** In the series' {{backstory}}, the extinct [[OurDwarvesAreDifferent Dwemer]] were masters at creating mechanical "[[MechaMooks animunculi]]", ranging from miniature [[SpiderMech spider centurion]] workers to sphere and steam centurion soldiers to full blown HumongousMecha. As the Dwemer were known to tinker with the "earthbones" (essentially the laws of physics and nature in the ''ES'' universe), they could make their creations [[RagnarokProofing impervious to wear and tear]], meaning that many are still up and running even thousands of years after their disappearance.
** ''[[VideoGame/TheElderScrollsIIIMorrowind Morrowind]]'':
*** Edwinna Elbert, Stewardess of the Ald-Ruhn Mages Guild, studies Dwemer creations. If one brings her a copy of a certain rare book, she'll mention how she wants to be one of these, believing [[GlorySeeker it will make her famous]].
*** In the ''Tribunal'' expansion, one can meet Ignatius Flaccus in Mournhold. Ignatius spends his time restoring Dwemer centurions to use as combatants in his robot arena. [[spoiler:Of course, he quickly learns the hard way that Dwemer creations tend to [[AIIsACrapShoot behave erratically]] if taken outside of Dwemer ruins]].
* ''Franchise/{{Fallout}}'':
** ''Videogame/FalloutNewVegas''
*** Mr. House of New Vegas has elements of this himself -- while his skills extended quite a bit beyond robots, it ''was'' a major focus of him and the company he created, [=RobCo=], and in the modern day his influence on the outside world mainly occurs through controlled and sometimes modified Securitrons. He's also implied to have had a hand in the creation of [[HumongousMecha Liberty Prime]].
*** In theory, this is 0's ''job'' in Big MT in ''VideoGame/FalloutNewVegas Old World Blues''. In practice, while he's not too bad at the mechanical side of things (his modification of [=RobCo=]'s Securitrons ''are'' more powerful, despite having been in the open seemingly without maintenance for centuries), his software skills are... not quite up to the task (his robots either a) have gone berserk or b) hates their job).
** ''VideoGame/{{Fallout 4}}''
*** The Mechanist is an expert of robotics and has an army of robot for terrorizing the Commonwealth and killing everything coming across their path, complete with a factory as the lair to mass produce the robots. You can become one after acquiring the Robot Workshop as well.
*** The Institute, and Father, also qualify to some extent with their synths: machines that emulate the appearance and behaviors of humans. While Gen 1 and Gen 2 synths look more like mannequins than people, Gen 3 synths are [[RidiculouslyHumanRobots practically indistinguishable from humans]]. How much the Institute qualifies as robot masters is largely dependent on [[WhatMeasureIsANonHuman whether one considers synths to be mere machines or living beings]].
* In ''Franchise/FiveNightsAtFreddys'', BigBad William Afton was a roboticist and SerialKiller who used his talents to create his own line of SuckECheeses to [[ChildHater prey on children in]].
* Dr. Elvin Atombender in ''VideoGame/ImpossibleMission'': "Destroy him, my robots!"
* Lord Agony from ''VideoGame/LocksQuest''.
* Dr. Wily and Dr. Light from the ''VideoGame/MegaManClassic'' games, whose main robots are coincidentally known as Robot Masters.
* Lightspeakers from ''[[VideoGame/NexusWar Nexus Clash]]'' are fragile, cheerful angels devoted to defending justice and protecting the innocent by building and maintaining an army of relentless robotic minions. They're much more positive than most examples of this trope, but their armies can be incredibly dangerous if they fall prone to the BlackAndWhiteInsanity that often tempts angels in the Nexus.
* In ''VideoGame/ProfessorLaytonAndTheCuriousVillage'', we have Bruno, [[spoiler:who built ALL of the inhabitants of St. Mystere with the exception of the late Baron Reinhold's daughter, Flora]]
* ''Franchise/SonicTheHedgehog'''s diabolical Doctor Eggman, whose portfolio includes trying to turn everyone in the world into a robot.
* Purge from ''VideoGame/SpaceChannel5 Part 2'' makes hundreds of robots to face off against Ulala. Apparently he's so talented, he mass-produced the Peace Carrier 8 times in under a day.
* ''VideoGame/{{Spyborgs}}'' have it's BigBad, Jackal, being a rogue roboticist whose army of machines dominates the city, and you need to stop him.
* Ju Shifang from ''VideoGame/SwordAndFairy6'' is a playable example. He [[SchizoTech builds remotely-controlled robotic bears]] in {{Wuxia}} setting! He carries one of them around in backpack form, and deploys it when battle begins.
[[/folder]]

[[folder:Webcomics]]
* Agatha Heterodyne of ''Webcomic/GirlGenius''.
* In ''Webcomic/{{Homestuck}}'', the {{Troll}} Equius Zahhak is quite skilled at building robots and cybernetic limbs. He does this so that he can blow off steam by fighting killer robots.
* Rika, a British example from ''Webcomic/RPGWorld''.
* In ''Webcomic/TheAdventuresOfDrMcNinja'', Sean "Dark Smoke Puncher" [=McNinja=] likes to build robot animals with laser vision and stuff. Their main job is to guard the family home, but that's just an excuse--he just likes making the suckers.
* Molly from ''Webcomic/TheInexplicableAdventuresOfBob'' builds lots of robots, [[SmartPeopleBuildRobots mostly for fun]]. Only one of them has turned out [[InstantAIJustAddWater sentient]] -- the one made out of a milking machine. Two of the others are made of ''[[{{Snowlems}} snow]]'', and of those, [[https://bobadventures.thecomicseries.com/comics/608 one]] can [[TransformingMecha transform]] into a giant ice [[SiegeEngines ballista]]. Yes.

[[folder:Web Original]]
* ''Music/DoctorSteel'', creating an army of giant robots, and having a robot band. And a lot of robot toys.
[[/folder]]

[[folder:Western Animation]]
* Jack Spicer from ''WesternAnimation/XiaolinShowdown'' uses a wide array of robots in addition to the series's magical {{MacGuffin}}s.
* ''WesternAnimation/TheTransformers'':
** The Quintessons, [[AmbiguousRobots who may or may not be machines themselves]], are perhaps the biggest example in the franchise. They're the original creators of the entire Transformer race, and seem to have created several species of metallic minions like [[ServantRace their Sharkticons and Allicons]]. Some media credits them with the direct creation of the animalistic Decepticon [[CombiningMecha combiner teams]] of the Predacons and Terrorcons. They seem to have a thing for making transforming [[AnimalMecha animal robots]].
** The supercomputer TORQ-III from the episode "Day of the Machines" is described as a "machine that can build other machines." When [[JerkAss Megatron]] reprograms TORQ to be hostile, TORQ commands all of the robots he's built to go on a rampage.
** Any of the [[TheMedic "medic" characters]], like Ratchet or First Aid, would qualify for "maintaining" robots. As MechanicalLifeforms, they just think of it in different terms. Wreck-Gar and Alpha Trion would probably count, too.
** Dr. Fujiyama, creator of Nightbird the robot ninja.
* ''WesternAnimation/TransformersAnimated'''s Isaac Sumdac, who reverse engineered technology from Megatron's head, resulting in Detroit being a center of robot production.
* Ming's flunky Dr. Tav from ''WesternAnimation/FlashGordon1979''. Dr. Tav invented Ming's army of MechaMooks.
* Though he has many other accomplishments, Dexter from ''WesternAnimation/DextersLaboratory'' is constantly building robots.
* Tobey from ''WesternAnimation/WordGirl'', with his mega-giant-attack robots.
* Dr. Von Richter from ''WesternAnimation/{{Cybersix}}'' specialized in biological androids.
* ''WesternAnimation/DuckTales1987'': [[BunglingInventor Gyro Gearloose]]. After [[RobotRebellion one disaster]], Scrooge [=McDuck=] specifically forbade Gyro from making robots, because AIIsACrapshoot. At least once Gyro attempted to get around this restriction by building [[GiantMecha piloted robots]], and rather than causing mayhem on their own, the Beagle Boys simply stole them and caused mayhem anyway. He tried once more in the third season, building a sentient [[SuperPoweredRobotMeterMaids robot maid]] who promptly fell in MadLove with Fenton and went berserk; Gyro ''was'' ultimately able to pacify her without having to junk her, though. Third time's the charm, apparently.
** Gyro's bad track record with robots is played up even more in [[WesternAnimation/DuckTales2017 the 2017 reboot.]] Frustration with his robots "turning evil" is actually what drives him to bypass A.I. entirely and build the piloted Gizmoduck suit instead. He did manage to create one robot that never went evil on its own, though: [[spoiler:2B0, AKA B.O.Y.D.]]
* Ziv Zulander from the appropriately titled ''WesternAnimation/TheBotsMaster'', a TeenGenius responsible for introducing semi-advanced robots, called [=3As=][[note]][[AddedAlliterativeAppeal Auto-Activated Androbots]][[/note]] to his world. He also built a bunch of even more advanced robots, who are sentient with human-like personalities, called BOYZZ[[note]]Brain-Operated Young Zygotopic Zoids[[/note]].
* In ''WesternAnimation/BoltsAndBlip,'' all the robots on the Moon were built by Dr. Tommy, except the evil MechaMooks who were built by [[NamesToRunAwayFromReallyFast Dr. Blood.]]
* Nora Wakeman, Jenny's "Mom" from ''WesternAnimation/MyLifeAsATeenageRobot.''
* Dr. Nightmare, a ''WesternAnimation/SpaceGhost'' villain who builds {{Mechanical Monster}}s.
* ''WesternAnimation/{{Kaeloo}}'': Olaf the emperor penguin has his own robot, which he uses to get anyhing he wants or needs. He also once [[spoiler: turned Stumpy into a cyborg]], and he built a robot army [[spoiler: in the second season finale]].
* Sunfire's [[MadScientist crazy]] uncle in the ''WesternAnimation/SpiderManAndHisAmazingFriends'' episode "Sunfire" first built a bunch of samurai-themed MechaMooks, then created a giant artificial fire monster (you know, the one from the show's opening credits).
* ''WesternAnimation/WanderOverYonder'':
** KnightOfCerebus Lord Dominator has an army of lava-powered robots as a DarkerAndEdgier counterpoint to Lord Hater's live army of [[AdorableEvilMinions Watchdogs]]. Amusingly, Lord Hater seems to ''think'' he's one of these (arguably a MythologyGag in that the Watchdogs were originally conceived as [[DoAnythingRobot Do-Anything Robots]]:
--->'''Hater:''' You know those eyeball guys I have? How often do I need to change their batteries?
** Aging villain Mandrake the Malfeasant has an appropriately retro army of [[TinCanRobot Tin-Can Robots]].
* ''WesternAnimation/OKKOLetsBeHeroes'': Lord Boxman creates all of his robotic minions, making a whole business out it. His corporation supposedly sells them to other villains, but his own obsession with destroying the plaza tends to stymie much of his sales.
