->'''Jack:''' [[TransformingMecha You're a motorcycle]], Arcee. Shouldn't you know how to build a motorcycle engine?\\
'''Arcee:''' You're a human, Jack. Can you build me a small intestine?
-->-- ''WesternAnimation/TransformersPrime'', ''"Masters and Students"''

Mechanical Lifeforms are a race of robots or robot-like creatures that are also considered a honest-to-goodness species of living things. They're just like your everyday living organisms, except they happen to have metal for skin, wires for nerves, and so on. They're often [[SiliconBasedLife silicon-based]] as well.

These may be robotic animals, plants, micro-organisms, or sapient creatures. If they are sapient, they would never wish to BecomeARealBoy because, as far as they can see, [[WhatMeasureIsANonHuman they are as real as that boy]].

The origin of such creatures is best left unexplained - they were never built by another race (well, that anyone knows of), and if they were, it would be treated as a ''very'' shocking revelation, due to the audience accepting their mechanical nature as-is. And should any creators arrive to cart them back, expect them to react just the same as humans would (i.e. much anger, denial, violence, and maybe a speech or two about free will).

Contrast OrganicTechnology, which are machines that happen to be organic in nature. Also see MechanicalMonster and MechanicalEvolution.

!!Examples:

[[foldercontrol]]

[[folder: Advertising]]
* Commercials for Omega wristwatches depict the interior of a watch as an entire mechanical world, complete with clockwork people, animals, vehicles, trees, etc.
* A few car commercials have featured robotic horses or greyhounds racing along as symbolic stand-ins for the cars they're selling.
[[/folder]]

[[folder:Anime]]
* The Mecha in ''Franchise/{{Zoids}}'' don't just look like giant animals. They also live in the wild and somehow give birth as well. There's a picture book called the ''Zoids Bible'' which shows the zoids originally evolved from a planet seeded with zoid cores, going through eras of evolution uncannily similar to those of life on our own planet; the zoids as we see them on the show are post-domestication. The Backstory is actually a lot more sinister. Natural wild zoid are mostly reasonably sized (sometimes they're large but nowhere as large as their current form). Their giant mechanical body? It's manufactured specifically for war purposes; Wild Zoid are captured and transplanted on those robots as cores....
* The characters from ''MachineRobo'', which bizarrely has humanoid robots and mech-like robots in the same series.
* The Rune-Gods from ''Manga/MagicKnightRayearth''. Though they're more like EnergyBeings clad in suits of armor than robots. There's even an episode in season 2 where a pilot of a true HumongousMecha tries to scan one of them and is baffled because he ''can't see any moving parts inside''.
* Tekkamen in their transformed states in ''Space Knight Anime/TekkamanBlade'' seem to be actually made of PoweredArmor. Occasionally, when it's dramatic, they retain scars into their human forms.
* ''Franchise/{{Digimon}}'': The "Metal Empire" digimon includes cyborgs and guys wearing metal armor; nevertheless, their numbers primarily consist of full on robots, from the gear-like Hagurumon to the GiantMecha given form, Machinedramon.
** Of course, since they're ''all'' sentient computer data, all Digimon are this regardless of their form.
* ''GaoGaiGar'' really messed around with this trope. First, there's Guy Shishioh, who's a traditional cyborg. The Zonders, Zonderians and 31 Primevals are also worth noting: the Zonders and Zonderians are organic beings that are transformed into some sort of techna-organic lifeform via exposure to Elementary Particle Z-O, which is released by [[GreenRocks Zonder Metal]]. They also have completely transformable bodies, and can assimilate metal, to the point where they can even move ''through'' it. The Primevals are the same. They just happen to [[spoiler: have the ability to assimilate ''anything'', not just humans]]. Then you've got ''Evoluders''...
** Special credit goes to the Zonderian, Penchinon: [[spoiler:it is later revealed that, aside from being a Zonderian, he is actually the A-I system for the J-Ark.]]
* The Neuroi in ''StrikeWitches'' are a mixture of this and Starfish Aliens, as they take forms ranging from rockets and experimental aircraft to humanoid designs, flying manta rays and six-limbed turtles.
* The villains in the new [[{{Galaxy Express 999}} Galaxy Express]] manga and ''Eternal Fantasy'' are a race of these. (The old ones were mechanized humans.)
* The titular Blue from ''BlueDrop''. It's entirely mechanical and is (re)made of nanomachine, but it moves and acts like a [[SpaceWhale mechanical whale]].
* ''AngelSanctuary'': [[EvilTwin Rosiel]] is a [[OrganicTechnology mechanical]] [[OurVampiresAreDifferent vampire]] [[OurAngelsAreDifferent angel-thingy]] as the [[PolarOppositeTwins complete opposite]] of his sister, Alexiel. [[spoiler: [[DeusEstMachina YHWH]]]] also counts. [[MindScrew And no, it's never explained how exactly this works.]]
* The titular Super Robots from ''GetterRobo'' tend to verge on this as the series goes on.
* ''Anime/VividredOperation'', SpiritualSuccessor to ''StrikeWitches'', has this in regard to its primary antagonists The Alone. Unlike Neuroi though, Alones actually have biological parts.
* ''SDGundamForce'' and other SD Gundam gag shorts feature chibi robots living alongside humans.
* ''ShippuIronLeaguer'' is about robots playing sports.
[[/folder]]

[[folder:Card Games]]
* In ''TabletopGame/MagicTheGathering'':
** The Mirrodin plane that the [[PhysicalGod Planeswalker]] Karn created has plenty of these. Probably because [[RobotBuddy Karn himself]] was one of these before he became a planeswalker.
** Phyrexia was inhabited by mechanical lifeforms, even before Yawgmoth took control of it.
* In ''TabletopGame/YuGiOh'':
** Ancient Gears are an entire Archetype of these.
** Most Monster Cards with the ''Machine'' type are either this, or Cyborgs.
[[/folder]]

[[folder:Comic Books]]
* ''NYC Mech'' features an entire world populated entirely by robots, who look and act exactly like people.
* At least one version of DC's ''ComicBook/{{Legion of Super-Heroes}}'' includes Robotica, a planet inhabited by a robot civilization, as well as the Linsnarians, a species of techno-organic people. In the cartoon version, the Coluan race (organic in the comics) is a civilization of humanoid robots not unlike the Linsnarians.
* Marvel has the Phalanx (and a related race, the Technarchy), which has recently been taken over by [[spoiler:Ultron, easily the most evil robot on Earth]]. Additionally, the Transformers sort of exist in Marvel continuity as part of their own timeline.
* At least one of them exists in ''Comicbook/{{Empowered}}'''s verse. She has the shape of an attractive human woman and is anatomically correct. One of the Superhomeys sleeps with her, and her nanites turn him into a mecha.
* The ''Franchise/MarvelUniverse'' has several.
** * The Celestials are technically [[EnergyBeing Energy Beings]], but they need to use HumongousMecha bodies to interact with anything.
** ''ComicBook/FantasticFour'': The Thing once befriended a robot named Torgo from the planet Mekka; Mekka's organic population had died out in a disaster long ago, but their robot servants had survived and gone on to build a civilization of their own.
** ComicBook/{{Warlock}}'s people the Technarchs presumably started out getting built by ''somebody,'' but they haven't answered to anybody else in a very, very long time.
** ComicBook/{{Quasar}} once fought a being called Skeletron, last survivor of an ancient race of robots called the Tugentine Techenium; he claimed that his race once tyrannized a huge chunk of Marvel space, but the organic races of that era united to destroy them.
** One of [[NextWave Aaron Stack the Machine Man's]] earliest foes was Ten-For, an agent of a race of robotic conquerors called the Autocrons.
** And there's even been a couple crossovers with ''Franchise/{{Transformers}}'', a franchise revolving around a race of TransformingMecha from the planet Cybertron; see the Toys section for more on that.
* The alien Malev robots in ''ComicBook/MagnusRobotFighter.''
* One specimen appears in one issue of ''PaperinikNewAdventures''. The comic doesn't give an explanation (only theories) about how such lifeforms and subsequent civilizations started... but one about [[AlienInvasion how it ended]].
[[/folder]]

[[folder:Films -- Animated]]
* ''WesternAnimation/{{Robots}}'': The robots from the computer-animated movie. They've formed their own society, and humans are nowhere to be seen or mentioned.
* ''WesternAnimation/{{Cars}}''. Even all the animals in their world are also vehicles: we have farm and construction equipment standing in for cattle, tiny [[StealthPun VW Beetles]] for insects, toy cars for dogs/cats/rodents, remote control aircraft for birds, and model trains for snakes.
* ''Franchise/{{Bionicle}}'' features biomechanical beings of a variety of different races [[spoiler: living inside the body of Mata Nui, who in turn is a living HumongousMecha around the size of [[GurrenLagann Chouginga Gurren Lagann]]]].
* ''WesternAnimation/TheIronGiant''. He can heal himself and he eats metal to live. His "stomach" even starts growling if he goes too long without food.
* In ''WesternAnimation/{{Nine}}'', the sackdolls are mechanical lifeforms imbued with the spirit of their creator.
[[/folder]]

[[folder:Films -- Live-Action]]
* ''Film/BatteriesNotIncluded'': The little robots can eat scrap metal and use it to build accessories for themselves, or even baby robots.
* Possibly applies in ''Film/TheDayTheEarthStoodStill1951'', the original one at least, based on Klaatu's statement.
-->"Klaatu":...We created a race of robots, and gave them absolute power over us."
** Klaatu also seems to indicate the Gorts are sentient to a point or at least capable of making decisions, when he says that without him, Gort could destroy the Earth
* ''Film/TheFifthElement'': It's hard to tell if the Mondoshawan are MechanicalLifeforms or aliens in PoweredArmor. It's vaguely implied that they are the former.
* As mentioned in the Toys folder, the [[TransformersFilmSeries Transformers]] are described as "autonomous robotic organisms." The term "Autobot" is apparently an abbreviation of this term.
** The films series plays heavily with the "lifeform" part as they eat, bleed, ''urinate'' and reproduce like any other lifeform despite being mechanical. During a fight, Optimus Prime even spits out a tooth!
** This trope becomes something of a plot point in ''TransformersDarkOfTheMoon.'' [[spoiler: Sentinel Prime's disdain for humanity partly stems from how the humans (particularly the US Government) view the Cybertronians, especially the Primes, as just machines. As he is quick to remind Optimus, "On Cybertron we [the Primes] were [[AGodAmI GODS]]!"]]
** Turned on its head in ''Film/TransformersAgeOfExtinction.'' [[spoiler:According to Lockdown, the Transformers were built by another race. Like the more antagonistic humans, these builders also view the Transformers as nothing but machines. Machines that they intend to reclaim.]]
* In the French film ''[[Film/LeGendarmeDeSaintTropez Le Gendarme et les extra-terrestres]]'' (''The Gendarme and the Extra-Terrestrials''), police sergeant Ludovic Cruchot discovers that aliens have arrived to Saint-Tropez. They turn out to be metallic inside, consume oil, but able to impersonate anyone and have MindOverMatter powers. Additionally, when exposed to water, they quickly rust and die.
* ''Film/EarthToEcho'' features a tiny mechanical alien who has been blinded needs assistance to get back home.
[[/folder]]

[[folder:Literature]]
* Many of Creator/StanislawLem's short story collections explore this notion, notably ''Literature/TheCyberiad'' and ''Mortal Engines''.
** In ''Peace on Earth'' and ''The Invincible'' by Lem self-replicating robots did "evolved away". In ''The Invinsible'', the pinnacle of mechanical evolution is TheSwarm of nano-machines, which is destructive of any other lifeform, organic or mechanical.
* Creator/TerryPratchett's novel ''Literature/TheDarkSideOfTheSun'' has an entire planet, Laoth, covered in artificial robotic life. Trees with solar panel leaves, tiny mechanical insects that eat other tiny mechanical insects, and ''[[MechanicalHorse talking robot horses]]''.
* ''Code Of The Lifemaker'' has a whole robot ecosystem. An autonomous alien mining colony [[GoneHorriblyWrong Goes Horribly Wrong]], developing into an elaborate ecosystem on Saturn's moon Titan. There are power-generator trees, mechanical animals up to and including intelligent, civilized forms (humans call them Taloids, they call themselves "robeings"--or a [[TranslationConvention word translated as "robeings"]], since they actually communicate via ultrasound bursts[[note]]You'd think it'd be radio, but the ultrasound was originally designed by the original aliens to serve as a local backup for when radio was impossible; part of Going Horribly Wrong was that the factories couldn't figure out how to make proper radios anymore; the few "robeings" who have vestigial radio capability are treated as prophets, since they receive transmissions but can't make head or tail of them[[/note]]) and factories as "farms" and birthing places, as well as electricity-based food. Being on Titan, there are hydrocarbon seas and an assortment of organic compounds, which the Taloids/robeings use to make tools and vehicles. They also have a form of civilization, with remarkable resemblances to late medieval Europe and particularly late medieval Italy (a [[CrystalDragonJesus Catholic-like church]], feuding city states, a scientist ostracized for suggesting that the world is round, and one state with a ruler famous for supporting the arts and sciences) that has recently undergone a scientific revolution, invented the gun, and is about to get hit with a major religious upheaval on account of FirstContact.
* The Gaijin from StephenBaxter's ''ManifoldSpace''. Extra points for being a naturally-evolved species. Characters first wonder who built them, but later travel to their home-planet (named 0-0-0-0) and observe an organism that was probably to the aliens what a chimp is to us--a metal crab.
* Terry Bisson's ''[[http://www.terrybisson.com/page6/page6.html They're Made of Meat]]'' is a short story which is entirely dialogue by aliens discussing their latest discovery: The messages they've recently encountered have originated from a planet which they're currently investigating, and it appears to originate from, well, ''meat''. The creatures are made of meat. Not creatures that are ''part'' meat, not creatures that go through a meat ''phase'', but creatures who live their entire (horribly short) lives in a stage of complete and utter meat. What's more, the messages are made by - you know how you can make a sound by hitting one piece of meat against another? They send out whole messages made entirely of meat-flapping sounds. Ghastly. [[spoiler: They're talking about humans.]]
** ArthurCClarke's short story ''Crusade'' is very similar, but the machines go further in their disgust and decide to wipe out the meat-creatures. Here they're explicitly rather than implicitly machines, and the exception that decides to destroy the rule.
* The ''YoungWizards'' series has the mobiles, computer wizards (that is, computers which ''are'' wizards) whose bodies are made almost entirely from silicon. There's traces of other elements too, which are apparently necessary for the forming and destruction of chemical bonds which give the mobiles energy.
** ...whose [[IncrediblyLamePun motherboard]], the planet from which they were created, was ''already'' sentient (although [[AndIMustScream completely lacking in sensory apparatus]]) before a certain wizard-on-Ordeal started messing with things. Also, the mobiles in question are [[RuleOfCute unutterably adorable]].
*** Said Wizard on Ordeal also pretty much counts as the entire race's mother/father due to this. [[spoiler:A Power That Be actually pretty much calls her that.]]
* In [[Creator/IainBanks Iain M. Banks]]'s [[Literature/TheCulture Culture]] novels, the Culture rates any lifeform, biological or machine, at a given level of intelligence to be a sapient creature, including the Minds that operate ships and colonies and run the Culture itself, Drones (for whom the word "robot is inadequate) and some spacesuits. And some weapons.
* Creator/GregoryBenford's ''Galactic Center'' novels include "mechs" which are implied to have evolved from self replicating von neumann machines. Left to their own devices after their biological creators destroyed themselves, errors and changes have occured in their templates over the millenia until their original functions were replaced by sentient self-direction. They seem to fear biological life [[spoiler:to the point of genocide.]]
* In the ''Literature/{{Animorphs}}'' books, the Chee are a race of fully sentient robots who were created by a long-extinct species of sapient dogs, the Pemalites. They hid on Earth after the Pemalites were hunted to extinction and use holograms to pass as humans; The Animorphs consider them sentient, but while whales are sentient enough that [[{{Trickster}} the Drode]] can't kill them, he can destroy the Chee because [[WhatMeasureIsANonHuman "they're robots"]].
* The {{Precursors}} in ArthurCClarke's ''TwoThousandOneASpaceOdyssey'' went through a stage of this as a part of their self-guided evolution, before going onward into {{energy being}}s.
* Both played straight and then inverted in a novel by German SF author Walter Ernsting (a.k.a. Clark Darlton) in which a human expedition not only makes first contact with an ancient peaceful robot civilization but discovers that [[spoiler:humanity itself]] evolved from an experimental line of organic androids once created by said robots.
* ''Striking Steel'' by Lyubov and Yevgeny Lukin featured replicating "antipersonnel complexes". One side in the interplanetary war deployed them, but with generations [[GoneHorriblyWrong the sum of the tolerable limits]] falls out of the friend-or-foe compatibility. So the whole planet was quickly [[AfterTheEnd stoneaged]] by mini-robot swarms, each [[MacrossMissileMassacre blasting to crumbles]] anything metallic it "see" moving save close relatives, and assimilating metal that doesn't move. Survivors adapted to such circumstances and developed some... quirks. The protagonist got there alive only because his suit and parachute were radar-invisible, after his shuttle's ECM [[StuffBlowingUp was proven not cool enough]].
* The Literature/{{Bolo}} Tanks are treated this way by their author, and they certainly meet the criteria, even if it has lacklustre representation from the characters in the books. One of the major themes is the disconnect between how they are treated in-universe and the fact that from the reader's objective perspective they are clearly the most honorable beings in the setting.
* The unexpected occurrence of this trope is the theme of Phillip K. Dick's short story "The Second Variety".
* ''TabletopGame/{{Warhammer 40000}}'': In the ''{{Ravenor}}'' series of books, a hive world (urban planet) is infested with robotic ravens of uncertain origin, known as [[MeaningfulName The Unkindness]], whose role appears to be simply to clean up rubbish from the ecosystem. However, it later transpires that a secret society knows how to control them, using them to kill their enemies and strip their bodies down to skeletons.
* Creator/GeneWolfe's ''[[Literature/TheBookOfTheNewSun The Urth of the New Sun]]'' has an interesting variant: Sidero is clearly some kind of mechanical man, but it turns out that his particular type of robot evolved out of [[spoiler:spacesuits with built-in artificial intelligence.]]
* The Inhibitors from ''RevelationSpace'' [[spoiler:were organic lifeforms that became sentient, self-replicating machines millions of years ago]].
* In SergeyLukyanenko's ''LineOfDelirium'' (inspired by ''VideoGame/MasterOfOrion''), the Meklar are LizardFolk who have replaced most of their organs with mechanical parts, including integrated weapons (plasma cannons and stunners in the chest plates). They are also superb unarmed combatants, given their machine-like reflexes. Their leader is known as the Perfect One, presumably because he replaced as much of his body as he could. A human sect views the Meklar as the most perfect beings in the universe and attempts to cyborgify themselves.
* An interesting case in Creator/IsaacAsimov's short story "Victory Unintentional", where humans send three highly-durable robots to [[ScienceMarchesOn the surface of Jupiter]] in order to study the Jovians (an advanced race that evolved on the planet), who wish to destroy humanity. After a series of mishaps, during which the aliens note the robots' durability, they sue for peace. The robots realize that they never told the Jovians that they were artificial lifeforms. The Jovians simply assumed that all humans are extremely tough mechanical organisms.
** Early MarvelComics character Doctor Druid once pulled this scam intentionally. He's a telepath, so he sat inside a gigantic crane with a wrecking ball and communicated telepathically with the alien invaders while slamming the wrecking ball into their ship. Fearing they would face an entire planet of such beings, they retreated.
* ''[[BillTheGalacticHero Bill the Galactic Hero on the Planet of Robot Slaves]]'' by HarryHarrison has the titular character end up on a planet locked in a civil war between two factions of mechanical lifeforms. According to one of the leaders, they have naturally evolved on the planet from primordial oil pools, although this doesn't stop them from building new ones.
* According to the poem ''Nothing in Heaven Functions as It Ought'', everyone who goes to {{Hell}} is turned into one of these. [[FateWorseThanDeath It's much less cool then it sounds]], since they're still in Hell.
* In the book ''All Tomorrows'' by Nemo Ramjet, a species of genetically engineered humans known as Ruin Haunters "evolves" itself into robots known as [[http://www.sivatherium.narod.ru/library/Ramjet/07_en.htm Gravital]] as their planet's sun begins to expand. They have no real definite shape and have human-level intelligence, individual personalities and opinions (having evolved from an organic human species). Although explained as not being "evil" they "simply did not acknowledge the life of their organic cousins", and [[OmnicidalManiac began wiping out all life in the galaxy]]. They ruled with an [[IncrediblyLamePun iron]] tentacle for 50 ''million'' years. Eventually they wage war with [[NinjaPirateZombieRobot insect-like human space-gods]] and are defeated. Afterwards, they simply become "normal" citizens of the New Empire but are [[FantasticRacism usually discriminated]] due to the "sins of their fathers".
* The dolls of ''Literature/TheDollmaker'' are an odd example. They're more golem than robot (although The Knife has clockwork parts), though they are defined as sentient beings with free will.
[[/folder]]

[[folder:Live Action TV]]
* In ''Series/StarTrekTheOriginalSeries'', the episode "I, Mudd" has an entire planet of androids that created new members as needed (e.g. the extra 500 Stellas).
** There is also Data from ''Series/StarTrekTheNextGeneration'', an android.
* The Replicators of ''Series/StargateSG1'' are a big nasty planet-eating HiveMind of MechanicalLifeforms. Also Asurans.
* ''[[Series/BattlestarGalacticaReimagined Battlestar Galactica]]'': The Cylons (which stands for [=CYbernetic=] Lifeform Node), especially in the new series where they are going organic. A bit different to some of the other entries as they make the transition from machine to living race within the timeframe of the setting. Interestingly no one on the Battlestar Galactica, no matter how much they hate the crazy toasters, ever seems to question the fact that they are alive and sentient.
** There was a ''lot'' of questioning this early in the series that went on all the way to the second season, with statements like "you have programming, not a soul", or "you can't rape a machine". Only after the occupation of New Caprica the general populace has had enough experience of the Cylons to realize that they are really people, even though machine people mostly considered somewhat unfairly, but for a fairly good reason (almost destroying the human civilization), evil.
** What's more, the Cylons can reproduce biologically. The current generation have only done so once and not amongst themselves - rather producing a HalfHumanHybrid - but [[spoiler:their forebears, the Thirteenth Tribe, reproduced amongst their own people all the time - resulting in a self-sustaining purely Cylon population: Cylon kids, Cylon grannies, Cylon aunts, etc. - until they built their own robots and got almost wiped out.]]
** The Original Series Cylons were LizardFolk who turned themselves into robots. Unlike most who do this, they still act just like any normal race, only they happen to be robots.
*** In the ExpandedUniverse novels, they go on to have a civil war between the all-mechanical Cylons and the partly-organic Cylons. This gets them off the Colonials' backs for a while, but they fear that whichever side wins will be that much stronger when the war ends and they turn their attention back to humanity.
* The Engines in ''Series/EngineSentaiGoOnger'' are mechanical lifeforms from a parallel universe.
** And the Guardian Beasts in ''Series/KyoryuSentaiZyuranger'' are actually ancient gods that for some reason look like HumongousMecha with cockpits and everything.
** The Power Animals of Series/HyakujuuSentaiGaoranger are (not entirely) mechanical lifeform ''nature spirits''. Their bodies are formed from the Earth itself. They just look like robots because they use metals for their skins.
** ''Series/SeijuuSentaiGingaman''. And the Franchise/PowerRangers counterparts of Gingaman and Gaoranger, [[Series/PowerRangersLostGalaxy Lost Galaxy]] and [[Series/PowerRangersWildForce Wild Force]], keep these qualities (Zyuranger's counterpart, the first season of ''Series/MightyMorphinPowerRangers'', on the other hand, turned the gods into "magical" giant robots with some degree of sentience - how much was never really explored, though they act on their own at times, and one episode had the Sabertooth Tiger Zord showing Trini the way to something needed to break the MonsterOfTheWeek's spell. Just one more area where MMPR kept the line between the tech and magic components of the same powers and equipment vague.)
[[/folder]]

[[folder:Tabletop Games]]
* The Machine People in the ''{{Rifts}}'' Phase World setting.
* ''TabletopGame/{{Alternity}}'': The mechalus from TSR's short lived game are an alien race that merged with machines at some point in their history. Essentially, each mechalus is born as a cyborg, pre-implanted with {{Nanotechnology}} from its family line. They were later adapted for the ''TabletopGame/D20Modern'' book ''d20 Future'', under the name "aleerin".
* ''{{Eberron}}'''s warforged were mass produced by humans as pseudo-living soldiers for the Last War, and when the war ended they suddenly found themselves without a purpose. Which would be fine if they weren't sentient beings with the same emotional range as their creators. By the time the setting opens warforged are facing FantasticRacism while trying to either integrate into humanoid society or create their own.
** Bizarrely while they don't need to eat, drink or sleep as expected 4e versions are still vulnerable to disease, poison and mind effecting attacks.
*** Justifiable on a meta and an InUniverse level; on the meta, it makes the game unbalanced if they are completely immune to disease, poison and mind-affecting attacks. From an in-universe perspective, one needs to remember that warforged are not "clockwork androids", but crystaline organs, stone bones, wood-fibre "flesh" and various alchemical reagents for blood wrapped in steel plating skin; poison and disease effects pollute their "blood" or affect the living wood that makes up their flesh. As for mind-affecting attacks, the basic idea is that any creature capable of such an attack can "tweak" the attack so it affects anything targeted.
* ''DungeonsAndDragons'': The modrons, clockwork beings from Mechanus, the Plane of Law in the ''Planescape'' setting. It's debatable whether they're actually mechanical, though, since they're basically the spiritual embodiment of Law in the same sense that angels represent Good and demons Evil. Supplanted by the Inevitables for third edition, who are more clearly robotic in nature (visible gears and whatnot).
* ''TabletopGame/{{KULT}}'' has the symbiotic lifeforms called Techrones. Aside from that, any mechanic equipment can be a vile lifeform in disguise.
* Subverted in ''Warhammer40k'' -- Necrons are ''undead'' robots, having turned to such in their [[ImmortalityImmorality quest for immortality]]. And now some of them want to turn ''back'' because they figured immortality isn't so awesome after all. Make of that what you will.
[[/folder]]

[[folder:Video Games]]
* Robots in ''VideoGame/SimEarth'', which can be obtained by nuking a nanotech city.
* An interesting example is the ''Franchise/MegaMan'' universe. What started as ordinary robots in the [[VideoGame/MegaManClassic original]] series were replaced by the ridiculously human Reploids in the ''VideoGame/MegaManX'' series. After many events and a brush with TheEndOfTheWorldAsWeKnowIt, they finally receive equal standing with humans in ''VideoGame/MegaManZX'', where they start blurring the lines between the two races. A few millenia pass, and both humans and sapient robots had pretty much become one species sometime around the extinction of traditional humans in the Legends backstory.
** ''VideoGame/MegaManLegends'' also include the Reaverbots, which are techno-organic creatures. Even in the MassiveMultiplayerCrossover, ''VideoGame/NamcoXCapcom'', they were labelled as unknown life forms and distinct from normal robots.
** The series also demonstrates some very odd background art. In ''X'', for example, humanity has seen fit to construct robotic woodpeckers that pluck robotic worms from robotic trees on robotic cliffs. [[RuleOfCool Yeah.]]
* The dragons of the ''{{Wild ARMs}}'' series are a race of living TransformingMecha. The demons, which have bodies made of metal, blood made of mercury, and astral forms made of electric signals, also count.
* The Mmrnmhrm race of ''StarControl''. Except they can't reproduce without the Mother-Ark, which has apparently not made any more after the initial batch (which was in the millions).
* Many [[ExtraOreDinary Steel-type]] ''Franchise/{{Pokemon}}'' belong to this trope. (Magnemite and evo's, for example)
* In ''{{Okami}}'', this is mixed with ScienceIsBad in that [[spoiler:Yami, the God of Darkness is the source of all technology and as such appears as a giant mechanical orb.]] This also applies to Lechku and Nechku, demonic Owls whose outer body take the form of {{Clockwork Creature}}, and several other demons.
* The Asuras in ''Franchise/ShinMegamiTensei: DigitalDevilSaga: Avatar Tuner''.
** Other examples in the series include the most powerful [[OurAngelsAreDifferent Angels]], such as Metatron, Sandalphon, Melchizedek and Ophanim, and the Innocents from IMAGINE.
* The bosses in the ''VideoGame/{{Darius}}'' series of side-scrolling shooters appear to be enormous spaceships in the shape of fish (or occasionally other aquatic life). According to the official backstory, however, these "huge battleships" are actually themselves alive.
* ''BioMetal'': The titular antagonists of the SNES ShootEmUp are these. Not surprising, [[MeaningfulName what with the name]].
* An odd borderline example presents itself in the S'pht race of ''VideoGame/{{Marathon}}'', which are apparently non-sentient creatures bonded with a special BlackBox upon birth which grants them sentience (courtesy of the [[SufficientlyAdvancedAliens legendary Jjaro]]). They think absolutely nothing of it until the first time they examine a normal sentient lifeform, they are completely flabbergasted and horrified by the very idea that their "birthing operation" may be what grants them sentience.
* In the ''GalacticCivilizations'' series of games, the Yor were originally created by the Iconians as servants but revolted against them, nearly wiping them out and forcing them from their homeworld.
* The Meklar from the ''VideoGame/MasterOfOrion'' series probably count. Although they originally started out as cyborgs, the Meklar race gradually became more and more robotlike to the point that it ultimately split in two in the third installment. Those who ultimately became purely mechanical kept the Meklar name, while their still partially-organic counterparts became the Cynoids.
* ''Franchise/MassEffect'':
** The geth. It is in fact common knowledge that they were created by the quarians, an alien race which is ''not'' extinct or long-disappeared, but their quick development from [[DoAndroidsDream questioning if they have souls]] to mechanical lifeform species raises some taut ethical conversations.
** The [[SapientShip Rea]][[EldritchAbomination pers]] are an even more straightforward example, although they get testy if you ask who "built" them. ''VideoGame/MassEffect2'' reveals that [[spoiler: they're at least partially organic. They reproduce by rounding up thousands of people, liquefying them, and pumping the genetic paste into a shell]].
-->'''Sovereign:''' Organic life is nothing more than a genetic mutation, an accident.
* While ''{{Spore}}'' leaves their exact origins a mystery, this, and their incredibly violent tendencies, are the two biggest traits about The Grox.
* In ''VideoGame/WorldOfWarcraft'' the Mechagnomes are fully sapient [[ExactlyWhatItSaysOnTheTin gnomelike mechanical lifeforms]] native to Northrend. It also turns out that [[spoiler:the regular, fleshy gnomes were actually devolved from the mechagnomes by [[EldritchAbomination Yogg-Saron]]'s Curse of Flesh.]]
** Most of the Titan (who were themselves made out of metal) constructs fall into this category, including the Earthens (who would become the Dwarves as a result of the Curse of Flesh) and the Vrykul (who would also become flesh because of th Curse and are the ancestors to the humans).
*** Barring the Mechagnomes, most of the Titan creations appear to have started as living or magically animated sculptures rather than machines. Some of the apparently uncursed giants can actually be mined like mineral nodes as opposed to dropping parts.
* Smithy and the Smithy Gang in general in ''VideoGame/SuperMarioRPG'' are this, living evil weapons in particular...
* Three planets in ''VideoGame/{{Meteos}}'' are inhabited by mechanical life forms (or at least deemed as such): Machines on the planet Grannest/Smogor, [[WesternAnimation/{{WALL-E}} built to serve the original inhabitants who have left without them]]; the robots on Mekks, who are fully sentient and run a [[AsteroidMiners space mine]]; and the electrical beings on Wiral/Neuralis, who tend to the surface while the actual population lives inside their world. Some of the Wiralons/Neuralisians are made of electricity and can also be considered as EnergyBeings.
* Platformer ''B.O.B.'' is a story of an adolescent robot driving his robotic parent's car to pickup his robotic girlfriend, complete with "where were you" remarks.
* Flash game ''Alchemia'' involved life forms created by an elixir of life. This results in a mechanical life form that became a ghost when it crashes and need to inhibit a new metal body.
* The Minirobots from ''VideoGame/MiniRobotWars'', who are created by the artificial planet they live on.
* The Xenon of the ''[[VideoGame/{{X}} X-Universe]]'' series began life as artificially intelligent terraforming drones created by Earth. [[AIIsACrapshoot A faulty software update made them go rogue]] and eventually they became fully sapient and "the greatest threat to biological life that ever existed throughout the whole universe." They have their own shipyards to build more of themselves. Predating them by roughly 500 million years are the Sohnen, a robot species used by the [[{{Precursors}} Ancients]] as an intermediary to the young races.
* The Mechon from ''VideoGame/{{Xenoblade}}'' are a race of {{Mechanical Monster}}s originating from Mechonis that have been in a long conflict against the [[HumanAliens Homs]] of Bionis. [[spoiler:They are also NOT lifeforms, much to the surprise of the protagonists. The real mechanical lifeforms are the Machina, the true humanoid inhabitants of Mechonis. The Mechon are just the creation of one of them]].
* Basically everyone in ''VideoGame/{{Primordia}}'' is a robot of one sort or another, what with humans having gone extinct.
* The Armada from ''VideoGame/{{Pirate101}}'' consist of clockwork soldiers that were built to help Valencia win the Polarian War. They were highly successful but have since taken over Valencia and have been threatening to take over the entire Spiral. They to not tire, they do not give up, they do not die![[note]]But they break if you hit them hard enough.[[/note]]
* The Exo in ''{{VideoGame/Destiny}}'' were created during the Golden Age to fight some sort of war, but later achieved sentience through some sort of subroutine. They're now counted as a separate species, though they still fight alongside humanity as Guardians along with the humans and Awoken.

* The Machine Men from ''RiceBoy'' actually grow as they age. One of them nearly dies from ''poisoning''.
** Some of the backstory provided in "Order of Tales" indicates that they even evolved from a more primitive rock-based form to their metallic, mechanical appearance in the present-day of the setting.
* Webcomic/{{Homestuck}} has quite a few examples. One of them is Jade's dreambot, which acts as a surrogate body when she's asleep. Another is [[spoiler: Liv Tyler the Rabbit, who is at least semi-sentient]]. Aradia's soul remains inside a robotic body for much of the Hivebent Arc. In addition, Dirk's Autoresponder is a computerized copy of his brain that lives inside of a pair of glasses.
* The [=TicTocs=] of ''Webcomic/GunnerkriggCourt'' aren't revealed to be robots until one of them gets autopsied. [[spoiler:It then takes root in the ground and starts growing.]] Did we mention that, aside from making their distinctive tic-toc noise, they look like ''birds''?
** The precursors to the Court's modern robots are part this and part golem as well. Kat does what is effectively ''heart surgery'' on one.
* ''SluggyFreelance'': The inflatable Dig Bots. They're self-replicating, have their own nightclubs, malls, religion, and fast food restaurants. They've even got a movie theatre where they play an edited version of ''WesternAnimation/{{Up}}'' that [[http://sluggy.com/comics/archives/daily/20100203 is much more sympathetic to their balloon brethren]].

* ''Franchise/{{Transformers}}'' contains the most popular examples of this trope. Most versions of the race's origin even hold that they were created by Primus, either a SufficientlyAdvancedAlien or an actual god depending on who you ask. Starting with ''WesternAnimation/BeastWars'', Transformers even have ''souls'', called [[OurSoulsAreDifferent "sparks"]].
** In the original cartoon, however, the Quintessons (themselves either mechanical or cybernetic) built Cybertron as a factory to produce robot slaves (non-transforming proto-Transformers). The robots rebelled, and kicked the Quintessons off Cybertron. Millions of years later, the Transformers have forgotten all about them, but the Quintessons still want their planet back. This has since been [[RetCon left out]] of almost all the following continuities, mostly in favour of the Primus origin. Notably, the ''Franchise/TransformersAlignedUniverse'' does feature the Quintessons as part of Cybertronian history, but that rather than building them for slave labour, they were an ''outside'' alien race who merely enslaved the already existing Cybertronian race and then ''lied'' about being their creators before they were rebelled against and kicked off-planet.
** In the comics, their original backstory was that they evolved from naturally occurring gears, levers and pulleys. Uh... yeeeeeah. This was eventually quietly forgotten in favor of the Primus origin, in which the Transformers were to be his trump card against his EvilCounterpart, Unicron.
*** Oddly, this is superficially similar to an origin provided in an obscure text story from a Japanese magazine. Basically, Cybertron was once a space station that developed sentience, absorbed materials from throughout the galaxy, and eventually changed itself into a planet with robot inhabitants.
** ''WesternAnimation/TransformersPrime'' goes into depth about their nature, when the Autobots meet the main human cast for the first time, Raf asks "So, if you guys are robots, who made you?" Ratchet is actually insulted by the implication that they were manufactured.
*** A humorous moment in "Masters and Students" has Jack trying to work on a regular motorcycle and Arcee (a motorcycle Transformer) is referring to parts as "doohickey." As Jack points out the irony that she doesn't know how a motorcycle works she asked if he could replicate a small intestine.
*** "Operation Bumblebee" has Starscream flat out state that what they have is more biology than machinery, as when Bumblebee gets his T-Cog [[OrganTheft stolen]] (Transformation Cog) it is stated that it is basically an organ and Ratchet can't just make a replacement from junkyard scrap. Given that some parts ''can'' be replaced, though, (Starscream gets a new arm at one point) it's probably akin to human prothetics where things like limbs can get replacements but internal organs are a lot harder to do.
*** Another episode of the original series involved a Decepticon and an Autobot ending up with each others transformation cogs. They had to be precisely adjusted in order to work properly (having only allowed unstable, partial transformation before the adjustments), which conforms to the idea that they function similarly to organs.
*** Things like surface plating appear to be fairly easily replicated and replaced. The "cosmic rust" incident began with Megatron having his chest plating damaged by a high speed projectile and Starscream telling him after they got back to base that a replacement would be fabricated "when they get around to it".
*** They even have ''genetic material'', cybonucleic acid (CNA). No, the name ''doesn't'' make sense, [[BellisariosMaxim lay off]]. The concept of MechanicalLifeforms having a "genetic" method of reproduction; however, ''does''. This has even been done in RealLife with digital creatures.

[[folder:Puppet Shows]]
* Though the mechanical characters in ''ThomasTheTankEngine'' know that they are artificial and even talk about being built by humans, they still fit this definition:
** The engines mention, often to other motorized characters, like cars or helicopters, that they don't want to be anything other than locomotives.
** There are a few sets of 'twin' engines that are canonically referred to as brothers.
** When the issue crops up, the steam-powered and diesel-powered engines appear to be considered two separate races. (Electric locomotives haven't come up yet.) Early stories even had noticeable FantasticRacism between the two, tied closely to the source of a lot of AscendedFridgeHorror. (LongStory.) Perhaps mercifully, this has since been quietly buried.
** The original books also had sentient coaches and freight wagons, and the mind boggles at where Diesel or Electric Multiple Units would fit into all this. [[note]]There's probably fanfic out there somewhere using them as an allegory for MalignedMixedMarriage.[[/note]]
** In short? This franchise gets really, ''really'' weird [[FridgeLogic if you think about it too hard]] and we suggest applying the MST3KMantra for the sake of your mental health.

* The ''AnimalMechanicals'' world is entirely populated by these, including the titular Animals, all designed to look like kid's building blocks.
* ''WesternAnimation/{{Futurama}}'': Professor Farnsworth unwittingly creates some. The life-forms evolve so fast that, within a few days, they put him on trial for promoting creationism.
