In sci-fi and anime you have your HumongousMecha and you have... this.

The Mobile-Suit Human is a MiniMecha designed to look like everybody else (more or less), manned by a tiny (usually about rodent-sized) pilot who can operate it to blend in with the rest of the population without being noticed; or to make himself seem more impressive than he otherwise would be. Nobody is ever afraid of anything tiny if it's not a KillerRabbit.

Most often employed for comedic purposes, the pilot of the suit is usually revealed at one point or another, to the astonishment and shock or amusement of who or whatever is unfortunate enough to be the one to open it up or see inside it.

The trope name is a pun on ''Anime/MobileSuitGundam''.

A potential subtrope of the MonsterSuit and HumanDisguise. For stories that depict ordinary humans as ''metaphorically'' controlled by tiny pilots, see GhostInTheMachine. See BrainWithAManualControl for when an actual human can be controlled like a robot from the inside of their body. For humans who are in mobile life support robots, see ManInTheMachine. See LittleGreenManInACan for different levels of alien and/or mecha.

For a more specific form of this trope, look to TotemPoleTrench.



* [[Creator/{{Syfy}} Sci Fi Channel]] has [[http://www.youtube.com/watch?v=_DH-v2G-aZg this commercial.]]

[[folder:Anime & Manga]]
* A strange, but almost direct play on this occurs in ''Basquash'': actually the HumongousMecha this show focuses on are later revealed to be created originally with the purpose to be a Mobile Suit Giant, allowing the humans to mingle easier with the race of the giants.
* ''Manga/{{Bleach}}'' has Mod-Souls, which are small consciousnesses that take the form of small yellow pills. There are also gigais, which Shinigami commonly use to interact with ordinary living humans. Combine the two (as they did in the Bount arc), and you get this trope.
** Nemu Kurotsuchi, is a Canon implementation of this concept. But unlike the mod-souls of the Bount arc, her artificial soul is permanently attached to her artificial body.
* A fantasy application of this trope: In the ''Manga/FullmetalAlchemist'' manga, [[spoiler:Envy's real body is revealed to be a small monster fetus thing that can generate or hijack a more ''human'' shell around itself.]]
** Similarly, [[spoiler:Father's apparent body is actually a container for a small amorphous blob-like creature which can't survive outside its container.]]
** In both of these cases, their true forms are the reasons for their villainy. [[spoiler:Envy deeply envies humans despite his vocal disdain for them, hence why he disguises himself as a human most of the time. Father desires freedom after spending his entire existence trapped in a container. Father seeks godhood because he believes that is the only way he can be truly free.]]
* Imoko, usually a small floating thing in ''Anime/TheGirlWhoLeaptThroughSpace'', has a [[http://static.tvtropes.org/pmwiki/pub/images/SoraKake-Mobile-Suit-Human-Imoko.jpg "Maid-Droid" human-sized robot]] that she can be seen using. Though she doesn't use the Maid-Droid very often.
* The main character from the ''Anime/JapanAnimatorExpo'' short "I Can Friday by Day!" is actually such a mech, piloted by a squad of tiny military extraterrestrial squirrels going deep undercover to look for a resource of some kind. Somehow, "she" is undercover so deep, she has a younger sister and a mother she lives with who don't know she's a robot. There are at least two other teenagers in the area who are also actually mechs for small animals.
* The titular heroine of ''Manga/KemekoDeluxe'' is actually a Mobile Suit Human that's BiggerOnTheInside.
* In ''Anime/{{Macross}}'', the Zentraedi are a humanoid species whose members stand about 30 feet tall. The HumongousMecha piloted by the humans are designed, on purpose, to be the same size. In one episode of ''Anime/SuperDimensionFortressMacross'', one of the characters even steals a Zentraedi uniform and puts it on his mecha to [[DressingAsTheEnemy pass as a member of the Zentraedi crew]].
* ''Manga/MahouSenseiNegima''
** The Life Size Host Robot Body Sayo-chan I that Haruna [[ArtInitiatesLife created]] for [[CuteGhostGirl Sayo]] to pilot from its abdominal cockpit with her [[HauntedFetter voodoo doll]] so she can form a Pactio with Negi. [[SuperPoweredRobotMeterMaids It also comes equipped with]] EyeBeams, RocketPunch, and torso-mounted [[GatlingGood Gatling Guns]].
*** The cockpit design is even a ShoutOut to Anime/MobileSuitGundam, it's exactly the same as the orignal Gundam, Guncannon, and Guntank, complete with the bulky fold-out targeting computer.
** There's also Chichigami, a fairly short mercenary who pilots the Paio II,a MiniMecha that wasn't revealed to be such until later.
* A bad guy in the ''Anime/MazeMegaburstSpace'' {{OVA}}s.
* A variant occurs in ''Manga/NewMazinger'', an one-shot painted ''Anime/MazingerZ'' graphic novel done by Creator/GoNagai and released by Dark Horse Comics: the titular super-robot is blasted into a sword-and-sorcery world where he rescues a topless princess (this IS Go Nagai, after all) from invading lizard-men. When the princess attempts to offer herself to the mysterious knight to persuade him to aid her people, he reveals that he is a machine piloted by a human "just the right damn size for a pet!"
* Nagisa Aizawa from ''Manga/MyMonsterSecret'' is a a HumanAlien who's about the size of an action figure and typically rides around in a mech that looks like a human-sized version of herself (the access port is a large screw on the back of her head [[UnusuallyUninterestingSight that nobody seems to notice]]). Her older brother Ryo turns up in a female suit, entirely so he can [[PeepingTom peep on girls in the bath]] -- [[LaserGuidedKarma and it comes back to bite him in the ass]] when fellow pervert Shimada falls for "her".
* ''Anime/NeonGenesisEvangelion'' presents a similar variation to ''Basquash'': the titular Evangelions, typically presented and marketed as HumongousMecha, are actually [[spoiler:humanlike armored mutants that can be piloted by regular humans]].
* Momo from ''Anime/PrettyRhythmRainbowLive'' who is a pink penguin (with hair) wearing a female human suit named Chisato Ibara.
* The alien frogs in ''Manga/SgtFrog'' use fake robot bodies when forced to interact with humans, [[PaperThinDisguise although we still see their normal faces.]] Incidentally, Keroro usually appears disguised as a woman.
** The more tech-saavy Kururu's manages a full body android disguise, but only manages to show off his trademark creepy geek side by making it look exactly like a cutesy teen J-pop idol.
* In ''Anime/SpacePirateMito'', the title character is about the size of a human third-grader, and resembles one. Her [[PoweredArmor battle suit]] is of a normal-sized shmexxy woman. HilarityEnsues when she has to leave it and it splits in half. So traumatizing for her son. It's later revealed that all [[PoweredArmor mail suits]] are modeled after the same woman, giving her son yet another shock when the BigBad's [[SamusIsAGirl helmet comes off]], revealing the same face as his mother.
* ''Manga/ZatchBell'':
** Baltro is an example. It's a foot-tall demon with telekinesis (more specifically, it can telekinetically control anything that has a special kind of flower attached to it). So until its defeat at the end of the story arc, Baltro hides inside an enormous suit of armor that it controls with that power.
** Koral Q, the {{tokusatsu}} madon, also qualifies.

[[folder:Comic Books]]
* ''Comicbook/TheAmazingScrewOnHead'' by ComicBook/{{Hellboy}}'s creator Mike Mignola is a {{steampunk}} AlternateUniverse where the title character is, for reasons unexplained, a head with a threaded bolt for a neck that can screw into various robot bodies, mainly humanoid.
* ''ComicBook/GoldDigger'' has the minor {{recurrer}}s the Vaulton Force, a parody of the main cast of ''Anime/{{Voltron}}'' as Leprechauns defending a vault full of gold. Their title mecha is about six feet tall when combined.
** It can also combine with its support mecha to a far more powerful ultimate form!... that stands seven or eight feet tall.
* ''ComicBook/TopTen'' features an intelligent talking Doberman Pinscher in a humanoid mechanical suit of armor.
* ''ComicBook/{{Hellboy}}'' villain Herman Von Klempt is simply a head in a jar. In the story ''Conqueror Worm'' he gains a robot body with the original biological head concealed in the chest.
-->'''Von Klempt''': Are you shocked at my true form?!
-->'''Hellboy''': We've met before! I KNOW you're just a head!
** {{ComicBook/BPRD}} agent Johan Krauss, who's pretty much a cloud of gas in a pressurized suit.
* In the Creator/MarvelComics' {{Retcon}} series ''Franchise/{{Marvel|Universe}}: The Lost Generation'', a [[UsefulNotes/TheGoldenAgeOfComicBooks Golden Age]] BrainInAJar hero called the Eternal Brain was given a robot named Walkabout to provide him with mobility.
* Franchise/TheDCU:
** Mr. Mind (a tiny but very evil Venusian worm) has been seen to use large robots as bodies when he's not taking over humans.
** The Brain went from, urm, [[BrainInAJar being a brain]] to possessing a certain robotic supervillain later on, then [[{{Squick}} professing his love to his French talking Gorilla, Monsieur Mallah]]....
* ComicBook/TheBeezer (and later ComicBook/TheBeano) had the {{Numskulls}} who controlled a real person, with various skulls in charge of different bodily functions.
** There were a number of [[{{Expy}} similiar strips]] in other BritishComics to The Numskulls with small variations the most common of which were changing the setting to a television rather than a human or having the characters inside the person be Germs. ComicBook/TheBeano currently runs both [[http://lewstringer.blogspot.co.uk/2012/04/variations-on-small-theme.html The Numskulls and The Germs.]]
* Number None, ''ComicBook/{{Nextwave}}'''s second DiscOneFinalBoss, turned out to be a robot piloted by a baby MODOK.
* One strip of ''ComicStrip/CalvinAndHobbes'' has Calvin imagining that this is what's going on inside of him as he trips down the stairs, and the ensuing panic that the tripping is causing among the crew. A later strip uses this as a metaphor for the phenomenon of dreaming, with the crew of Calvin's brain descending into the subconscious to gather random reels of tape and then playing them out of order.
* Early on, the original ''[[Comicbook/TeenageMutantNinjaTurtlesMirage Teenage Mutant Ninja Turtles]]'' comic book introduced the Utroms, as species of vaguely brain-like aliens who, after being stranded on earth to to Mobile Suit Human exoskeletons in order to blend in with the population.
* The "Hero Machines" in ''Danger Club''. They're from Micro-Tokyo, which is something like the Tokyo metropolitan area after being shrunk down and moved to another dimension. Pilots are around 6 inches tall, while the mechs themselves are roughly 6'10 or 7'; massive from their perspective, but simply large from ours.

[[folder:Comic Strips]]
* A Sunday strip of ''ComicStrip/CalvinAndHobbes'' has a fantasy spot in which Calvin is a Mobile-Suit Human being operated by a crew of little Calvins.

[[folder:Films -- Animation]]
* The main characters in ''WesternAnimation/{{Ratatouille}}'' played with this trope: one is a pilot/Chef and the other is an expert at being/[[ShapedLikeItself appearing human]], at least [[CharacterDevelopment at the beginning]].
* According to ''[[AllThereInTheManual The Art of]] WesternAnimation/ToyStory2'', the evil Emperor Zurg is actually a miniature alien in a suit of armor.

[[folder:Films -- Live-Action]]
* In a very ''un''-comedic example, the aliens in ''Film/DarkCity'' used corpses as {{Mobile Suit Human}}s.
* Done hilariously in a skit in the Creator/WoodyAllen movie ''Everything You Wanted to Know About Sex'', complete with a control center in the brain (infiltrated by a religious "spy" mid-coitus) and paratrooper sperm. Seriously.
* Got a rare serious turn in ''Film/IndependenceDay'' -- [[spoiler:the roughly human-sized alien invaders turnes out to be biomechanical suits; the real deal are child-sized. They are implied to be physically weaker, but [[TheGreys by no means disarmingly cute]].]] In the novelization, it is explained that they're not ''just'' [[spoiler:biomechanical suits]]... They are literally [[spoiler:ANOTHER alien species that the BigBad conquerors had defeated, found them to be useful, and [[BodyHorror TURNED THEM INTO THE SUITS!]] Or perhaps they somehow evolved some sort of symbiotic/parasitic relationship... psychic revelations like that tend to be unclear.]]
* The 2008 Film ''Film/MeetDave'', an Creator/EddieMurphy vehicle, takes this to extremes, featured a suit that looks like... Eddie Murphy. And is captained by... a miniature Eddie Murphy (actually a tiny humanoid alien). And is also a spaceship with about a hundred crewmen, making it a HumongousMecha at the same time.
* ''Film/MenInBlack'':
** The alien prince of the Arquillian Empire who had the Galaxy was piloting a Mobile Suit Human, the better to hide from enemies -- and to pet his cat.
** Subverted with a side of BodyHorror by the villain of the movie -- while he is using a human guise for the majority of the film, referred to as an "Edgar-suit"; it's actually the skin of a farmer he killed in the beginning of the movie. Also could be considered an inversion, in that the "pilot" of the suit is somehow ''much'' bigger than the human he's pretending to be (or the ship he arrived in for that matter).
* A truly excellent example in the ''Film/ScoobyDoo'' movie. [[spoiler: The villain turns out to be Scrappy inside one of these.]]
%%* ''Film/StarKid''

* ''Literature/TheMoteInGodsEye'' by Creator/LarryNiven and Jerry Pournelle. A human spaceship is overrun by "Brownies" - monkey-like animals that breed like crazy and use advanced technology by instinct. When the humans evacuate the ship, several Brownies try to tag along inside a human space suit. They operate the limbs from inside, and put a severed human head into the transparent helmet for camouflage.
* Creator/HarryHarrison:
** In ''Literature/BillTheGalacticHero'', the spoof of military sci-fi, SpaceCadet "Eager" Beager turns out to be a Chinger spy living in the head of a human-looking robot. The Chinger aliens were presented as giant lizards in the official military propaganda, but they are actually seven inches tall.
** The inverse (a human concealed inside a robotic alien suit) happens often in Creator/HarryHarrison sci-fi, such as ''Repairman'', ''Literature/StarSmashersOfTheGalaxyRangers'', and ''[[Literature/TheStainlessSteelRat The Stainless Steel Rat Wants You]]''.
* And an even earlier version comes from Creator/EdgarRiceBurroughs' ''Literature/JohnCarterOfMars'' series; the Kaldanes are head-sized insectile beings who symbiotically live atop the bodies of Rykors, which resemble headless humans, connecting themselves to the Rykors' spinal columns to "drive" them.
* ''Literature/{{Animorphs}}'' features a subversion. Normally the Yeerks enslave humans by basically turning them into biological versions of this. Eventually an android captures one and places it in his skull, unable to enslave it the Yeerk is trapped in a Mobile Suit Human with no access to the controls.
* ''Literature/BrokenAngels'' by Creator/RichardKMorgan. A child is seen using the brain-dead body of a cyborg soldier this way; he rides on his back.
* [[spoiler:Skool]] from the novel ''Literature/UnLunDun'' by Creator/ChinaMieville. For most of the story, he appears as [[spoiler:a big strong human in a diver's suit]]. Turns out, [[spoiler:the suit is actually full of water and inhabited by a school of fish, hence his name]]. Also, [[spoiler:the mercenary Mr. Cavea]]'s human body turns out to be just a suit. And the examples can go on.
* ''Man-Fac'' by Creator/MartinCaidin: the main character suffered crippling burns. He built a "Man-Facsimile" to allow him to get around. Although his body had been somewhat shriveled and shrunken by his injuries, the facsimile still needed to be of a very ''large'' man, seven feet tall or thereabouts, to fit him inside along with the mechanical muscles.
* Deconstructed in Rog Phillips' short story "Rat in the Skull", in which a newborn white rat is placed in control of a MobileSuitHuman as a psychological experiment, and grows up thinking the robot body ''is'' its body.

[[folder:Live-Action TV]]
* ''Series/DoctorWho'':
** The Slitheen from [[Recap/DoctorWhoS27E4AliensOfLondon "Aliens of London"]]/[[Recap/DoctorWhoS27E5WorldWarThree "World War Three"]] wear skinsuits to disguise themselves as humans. In an inversion, however, they're much bigger than the humans they're impersonating, and use compression technology to shrink down to fit. It still ends up looking like the humans in question gained large amounts of weight, though. In ''Series/TheSarahJaneAdventures'', however, the Slitheen eventually develop improved versions of the technology that allow them to fit into skinnier bodies.
** In a "Meanwhile in the TARDIS" extra.
--->'''Amy:''' What kind of an alien [are you]?\\
'''The Doctor:''' Well, a nice one; definitely one of the nice ones.\\
'''Amy:''' So you're like a-a space . . . squid? Or something... are you like a tiny little slug in a human suit? ''[The Doctor gives her a sour look]'' Is that why you walk like that?
** The Teselecta, in the episode [[Recap/DoctorWhoS32E8LetsKillHitler "Let's Kill Hitler"]], is a shapeshifting humaniform robot piloted by miniaturized humans who traveled back in time to, you guessed it, [[HitlersTimeTravelExemptionAct kill Hitler]].
* The short lived Saturday Morning show ''Series/LosLuchadores'' had an evil chihuahua who operated a man-sized robot.
* In ''Series/NinpuuSentaiHurricaneger'', villain Sargain was a small, ant-like alien operating a man-sized armored robot. His ''Series/PowerRangersNinjaStorm'' counterpart Zurgane didn't include this and was... uh, we're not sure (although his action figure incarnation did have a removable helmet showing the bug piloting the robo-suit, which surely confused a few fans unfamiliar with the original show). Sargain would then operate HumongousMecha, meaning he was piloting a robot to ''[[MetaMecha make it pilot another robot.]]''
* Kevin is purported to be one of these in an episode of ''Series/TheOfficeUS''.
* ''Franchise/{{Stargate|Verse}}'':
** The Goa'uld are a biological variant, usurping control of a living human host. It's explained that the reason humans were popular for this role (as opposed to their previous hosts, the Unas) were because human bodies were easy to repair.
** The Tok'ra (a rebel faction of Goa'uld) defy this trope by sharing control with their human host rather than forcibly taking it from them.
** Jaffa, the soldiers of the Goa'uld, additionally serve as incubators for Goa'uld larvae, which they carry in a pouch on their stomach. However, they cannot control the Jaffa soldiers directly.

[[folder:Puppet Shows]]
* ''Film/TeamAmericaWorldPolice'': Turns out there is a cockroach that was piloting Kim Jong Il.

[[folder:Tabletop Games]]
* In the ''TabletopGame/{{Trinity}}'' RPG by Creator/WhiteWolf the alien Qin use these, but most of the time it's subverted, since the suits, though human shaped, are obviously alien. They're just more practical for interacting with humans than their natural small 'furry squid/slug' form. In one particular plot a faction of Qin tried to use 'perfect human replica' suits to infiltrate a radical, racist, Slavic supremacist terror group, but only having a limited understanding of human culture, they used a suit modelled on an ethnic African appearance. Needless to say, HilarityEnsued.
* In ''TabletopGame/HcSvntDracones'' [[PettingZooPeople Vectors]] with the "Lateral" morphism look like normal animals, what with their size and lack of hands (or even limbs in the case of snakes) they have a bit of trouble functioning in technological society. A Body Socket is a robotic rig that gives them hands and upright posture.

[[folder:Video Games]]
* ''VideoGame/EarthwormJim'' is a foot-tall worm piloting an indestructible supersuit. A few scenes boot Jim out of his suit and he has to chase it down/endure the boss until he can reclaim it.
* ''VideoGame/CaptainCommando'' has [[http://www.arcadeflyers.com/?page=flyer&db=videodb&id=182ℑ=7 a playable character]] that is a super-intelligent baby riding a human-sized, headless robot. During the game, characters and enemies [[http://www.arcadeflyers.com/?page=flyer&db=videodb&id=182ℑ=5 can ride other headless mechas]], so you can have a baby riding a mecha that rides a mecha.
* In ''VideoGame/MeatBoy'', Dr. Fetus sits in a mobile glass container. Which wears a tuxedo and a monocle and is occasionally able to fly.
* The [[https://wiki.teamfortress.com/wiki/Tiny_Texan Tiny Texan]] item in ''VideoGame/TeamFortress2''.
* Sir Waddlelot from ''VideoGame/RibbitKing'' is a wind-up penguin piloted by a small ghost creature. According to the [[AllThereInTheManual bottlecap descriptions]], the ghost creature is a MadScientist named Dropsie.
* In the ''VideoGame/KatamariDamacy'' series, wearing the Mask present as Velvet makes her face open up like a hatch and reveal a smaller version of herself "piloting" her.

[[folder:Web Comics]]
* ''Webcomic/CinemaBums'' features a [[http://www.cinemabums.com/?p=187 strip]] where Mr. Potter from ''Film/ItsAWonderfulLife'' is actually one of these.
* ''Webcomic/SluggyFreelance'' has Bun-Bun build human-sized mechanical costumes for himself and Kiki (a rabbit and ferret, respectively) so they can masquerade as Riff and Torg on Halloween and steal candy from Trick-or-treaters.
** Similarly, Frog's Frech (Frog-Mech), which parodies [[Franchise/StarWars Darth Vader]].
* ''Webcomic/MechagicalGirlLisaANT'' takes this to an interesting conclusion, as the heroine's Powered Armor was supposed to be a Humongous Mecha for its inventors.
* Sam Starfall of ''Webcomic/{{Freefall}}'' is a boneless squid-like creature occupying a humanoid suit that provides an exoskeleton to allow him to keep a humanoid form for interacting with a human world, walk on dry land, and provide him with [[http://freefall.purrsia.com/ff1000/fv00907.htm a breathable atmosphere]]. As a bonus, the suit protects him from being added to the dinner menu of just about every terrestrial animal he encounters. And from what he firmly believes to be a human nurturing instinct (when they see his true form, they regurgitate their last meal.)
** It's necessary not only because of how Sam's ''looks''. He also [[http://freefall.purrsia.com/ff2200/fc02109.htm sweats ammonia.]]
* In ''Webcomic/ItsWalky'', [[spoiler:Alan]] is revealed to be an alien in such a suit.
* ''Webcomic/PastelDefenderHeliotrope'''s follow-up series ''Webcomic/ToSaveHer'' has an unusual inversion: Kaye is an amorphous [[BlobMonster blob]] who wraps herself around a skeletal armature to assume a humanoid form.
* [[spoiler:Sin]] from ''Webcomic/SamAndFuzzy'', is one of these.
* A few [[OurAngelsAreDifferent angels]] from ''Webcomic/{{Blip}}'' used these near the beginning.
* Occasionally used by smaller species in ''[[Webcomic/TwentyFirstCenturyFox 21st Century Fox]]'', though mostly in [[http://techfox.comicgenesis.com/d/20040105.html emergency situations]]
* In ''Webcomic/PvP'', Scratch Fury turns the Ottobot into one of these. After learning to use it to (somewhat) convincingly pass himself as a human, he tries uses it to try to take over the Mayor's office. [[RealityEnsues He's immediately thrown in jail]], forcing him to leave the empty suit behind.
* In ''Webcomic/GeneralProtectionFault'' [[spoiler:Mr. Intertia]] turns out to be one of these operated by a pair of greys.
* One of the Wulfenbach allied Mechanicsburg attackers in ''Webcomic/GirlGenius'' is revealed to be a mass of mice masquerading as a human after he gets a hole in his torso. Either that or he's a Spark who for some reason decided to modify his torso to house mice, which is also possible.

[[folder:Web Original]]
* Doctor Infanto, a supervillain active in the ''Roleplay/GlobalGuardiansPBEMUniverse'' is a super-intelligent infant who interacts with adults while wearing a "grown-up suit" that allows him the full range of motion that his still-underdeveloped body makes difficult. Imagine a baby's head on Creator/ArnoldSchwarzenegger's body and you have the right idea.
* In the Literature/WhateleyUniverse, Rack fits this trope. He looks pretty much like a normal-sized guy in power armor. But he's really a small dwarf in Mobile Suit Human hardware that he built. He operates it using hand controls and telekinesis.
* In the ''Duke Forever'' chapter [[http://absurdwordnerd.blogspot.com/2014/06/mister-heavy.html Mister Heavy]], the titular character is at first mistaken for a {{Superhero}}, but is later revealed to be a spaceship for a race of intelligent, alien caterpillars.

[[folder:Western Animation]]
* The recurring villain for ''[[WesternAnimation/ThreeTwoOnePenguins 3-2-1 Penguins!]]'' is Baron Von Cavitus, in actuality a mechanical suit driven by a hamster named Bert Bertman.
* ''WesternAnimation/AdventuresOfTheGummiBears''- in one episode, one of the Gummis used a ClockPunk human-sized suit of armor to masquerade as a human. It did well for a while, but then the limbs started coming off...
* ''WesternAnimation/Ben10AlienForce'' has Vulcanus. Deprived of his PoweredArmor, he turns out to be only 2 feet high, and half of that is his head.
** There's also the creator of the Onmitrix, who turns out to be an older version of Ben's Grey Matter alien, but only when we first see him in ''Ben10SecretOfTheOmnitrix''. His other-dimensional counterpart in ''WesternAnimation/Ben10Omniverse'' episode "Store 23" also appears in one.
* A gag in the title sequence of ''WesternAnimation/BountyHamster'' shows Cassie trying to hire a bounty hunter, and selecting a hulking figure in powered armour - which immediately falls apart, revealing the title character. (The armour never appears or gets a mention during the actual episodes.)
* One episode of ''[[ComicBook/BuckyOHareAndTheToadWars Bucky O'Hare]]'' features one of these played as TheMole. Or technically, the walrus, or the chairman.
* ''WesternAnimation/BuzzLightyearOfStarCommand'' had the (ironically named) Gargantuns who were six inches tall. Dissenting Gargantuns would often times use normal sized suits to blend in and attack their targets. (One such case featured framing Buzz Lightyear by wearing one of these suits and attempting to kill the Galactic President who was signing an important treaty. They then attempted a Xanatos Gambit by demonstrating a suit that looked like the President and pretending to use it to derail the peace treaty, all to get the real Buzz to shoot the real President.)
* Technically, Grizzle from ''Franchise/CareBears: Adventures in Care-a-Lot''. He wears a suit that makes him appear to be large and intimidating, but in reality he's slightly smaller than the Care Bears.
* An episode of ''WesternAnimation/ChipNDaleRescueRangers'' had Gadget make a matador machine out of random junk so the team could bullfight El Emenopeo.
* In his debut episode, Skulker from ''WesternAnimation/DannyPhantom'' is a metallic ghost, revealed to be a tiny ghost about the size of a gerbil, who wears a pretty badass suit of armor. Fortunately for him, that detail seems to have been dropped.
* One episode of ''WesternAnimation/FamilyGuy'' has Stewie use a robo-Peter suit [[ItMakesSenseInContext in an attempt to prevent the real Peter from having another baby]]. Seeing Stewie emerge from the robot's stomach after it falls out the second-story window causes Cleveland to ''freak out'' a-la ''Series/HogansHeroes''.
-->'''Cleveland:''' ''(walks away)'' I see nothing. I see nothing.
* One of the {{Couch Gag}}s in ''WesternAnimation/TheGrimAdventuresOfBillyAndMandy'' has Mandy's face opening to reveal a smaller Mandy, who then utters [[Franchise/StarWars "Echuta"]].
* ''WesternAnimation/InvaderZim'' has "Government Man", a robotic [[TheMenInBlack Man in Black]] piloted by GIR that looks even more like and android than him.
* In the ''WesternAnimation/MenInBlack'' cartoon series, there were many Arquillians living on Earth, and their suits were [[SuperPoweredRobotMeterMaids very powerful compared to humans.]] In one episode, another similarly-sized race, the Fmek, ran around body-jacking the pacifist Arquillians to use their suits against them.
** It goes even further with Microcephalopoids, aliens so small that they use Mobile Suit ''Arquillians'' to ''[[MetaMecha pilot]]'' Mobile Suit Humans.
* One episode of ''WesternAnimation/PhineasAndFerb'' showed Mr. Flynn-Fletcher's body being revealed to be a suit piloted by Perry the Platypus at one point in said episode. Another had an alien in a Mrs. Flynn-Fletcher suit so he could learn about the habits of Earthling mothers while Phineas and Ferb repaired his spaceship.
* Brain's human outfit from ''WesternAnimation/PinkyAndTheBrain'' is a mechanical human body topped off by Brain's own head. He claimed his tiny head and large ears were the result of a "medical condition". On another occasion, he stated outright, "[[SarcasticConfession Actually, I'm a laboratory mouse in the advanced stages of a plot to take over the world.]]"
** One episode reveals [[strike: Bill Gates]] [[LawyerFriendlyCameo Gill Bates]] to be a suit piloted by Brain's archrival Snowball the Hamster.
* Roach Coach, from ''WesternAnimation/ThePowerpuffGirls'': a one-off villain who despises humanity and has a device that let him control roaches. He appears at first to be an ordinary man (with antennae), but he turns out to be a roach in a robot human suit.
* Right on the line between this and HumongousMecha, in ''WesternAnimation/SamuraiJack'' Episode XVI, "Jack & the Smackback" (aka the Dome of [[DoomyDoomsOfDoom Doom]]), Jack fights The Aqualizer, which, while quite large, we discover after Jack lays the smackdown on it is controlled by a rather tiny sea slug-looking critter.
* One episode of ''WesternAnimation/{{Sealab 2021}}'' sees most of the crew of the eponymous research station's bodies turned into these for mice, while the crew themselves have their brains put into giant robots. It is made more amusing by the fact that the whole cycle was started because the captain of the station had scandalous photos of the science officer engaged in sexual acts with a fat intern, which said captain was threatening to show to said science officer's girlfriend...and the science officer spent 90% of the episode drunk.
* ''WesternAnimation/TheSecretFilesOfTheSpyDogs'' had Humanesks, which pretended to be fat humans. They had spy dogs as pilots.
* On ''WesternAnimation/SpongebobSquarepants'', Plankton will sometimes dress up in robot contraptions that make him equally big as the rest of the cast. Not exactly ''human'', though. Generic fish or Mr. Krabs himself are his favourites.
* ''WesternAnimation/StarWarsTheCloneWars'': In [[Recap/StarWarsTheCloneWarsS2E17BountyHunters "Bounty Hunters"]], one of the titular characters is a hulking armoured figure named Seripas -- who, true to this trope, turns out to be a diminutive alien about half a metre tall.
* ''Franchise/TeenageMutantNinjaTurtles'':
** Krang from the [[WesternAnimation/TeenageMutantNinjaTurtles1987 first cartoon]] was loosely based on the original concept of the Utroms, although his own humanoid exoskeleton was decidedly not designed for blending in.
** [[WesternAnimation/TeenageMutantNinjaTurtles2003 The second series]] brought the Utroms (from the original books--see above). An Utrom named Ch'rell, in particular, was one of the series' main antagonists, and was almost always in one of these.
** [[WesternAnimation/TeenageMutantNinjaTurtles2012 The third series]] has these piloted by the Utroms' {{exp|y}}ies, the [[AlienInvaders Kraang]], who turn out to be a a rouge splinter group of the Utrom themselves mind-controlled by Kraang Prime and commanded by Kraang Sub-Prime.
* The Pretenders in ''{{Transformers}}'' were suits ''for'' the titular giant robots, either disguised as humans or monsters. It was never explained ''how'' the Cybertronians could hide with these suits, considering they were still giant robots. The concept works fine in animation (due to Transformers often changing sizes, known in the fandom as "mass-shifting") and the Decepticon Pretenders (almost all of them have monsters for shells), but for the Autobot Pretenders (who are basically all humans), it causes major scale discrepencies in the toyline.
** In the comics, some planets happened to have Transformer-sized humans. Which explains the Pretenders, but [[FridgeLogic opens up a whole new set of questions]].
** In the Japanese continuation series ''Transformers Masterforce'', the Pretenders are shown to basically be improved Micromasters: they are only human sized.
** Considering the size of the Transformers from the ''Beast Wars'', it isn't unlikely that this is prelude to the "Great Upgrade" that allowed them to don more energy efficient, human-sized bodies.
* The OneEpisodeWonder "Troy Ride" from ''WesternAnimation/ShortyMcshortsShorts'' is based on this trope.
* ''WesternAnimation/YoungJustice'' has the Kroloteans who pose as kidnapped humans.

[[folder:Real Life]]
* Though not mobile, the Mechanical Turk -- an 18th century "chess-playing automaton", which was secretly operated by a man hidden in its base -- is perhaps the closest RealLife has come to one of these. Its clockwork arm ''did'' move, via a complex series of levers.
* When you think about it, the body is like a mobile suit for the brain...
