Mechanical Abomination

Go To
Destroy all you want. More will be built.

"Hear me Mandus. My gears are adjust, my steam is built. Soon I will spill that blue water and split the egg, the atom, my soul and there will be a very great burning that we might make the world clean. Be proud, for this is your doing. Until you steeped me in the blood of your own I was nothing but rotten architecture. You have made me, and I will make the world anew."
The Machine, Amnesia: A Machine for Pigs

Not every monster comes from outer space, or another dimension, or an ancient myth. Some are built. A Mechanical Abomination is an artificial intelligence that has become so powerful it defies comprehension, either through Mechanical Evolution, The Singularity, alien origins, or some other process. It's more advanced than anything else in existence, and it's more likely than not coming to destroy us. Cyborgs are not necessarily excluded from this trope, especially if the organic components are also artificial, but the technological aspect of the entity should be emphasized.

These things come in two main varieties: The first is often between levels 4 and 5 on the Sliding Scale of Robot Intelligence. Unlike other monsters on the level of Cosmic Horror, this Mechanical Abomination is defined as much by its immense intelligence as its raw power, meaning it can communicate with humans and human-like beings and take notice of their actions. Bonus points if its thought process is something totally alien and unrelatable, or if it simply just doesn't care about other intelligent life or only sees it as a convenient means to an end. Misanthropic hatred doesn't necessarily disqualify it, mind you - it's just far easier to understand than something that is totally apathetic or selfishly pragmatic.


Other times, they're just twisted constructs that make you wonder how it's possible for them to function. Despite their mechanical appearances, they do things far beyond what typical technology can, disregarding normal physics. They're bizarre and often terrifying, but ultimately act according to whatever purpose they serve and aren't particularly sophisticated. They might actually even be Magitek constructs, working not on the laws of physics or normal programming as you know them. Expect them to look more like Starfish Robots most of the time.

This trope also lists artificial intelligences or programs with horrifying power, as seen in the Skynet (Terminator) example below.

Compare Mechanical Monster (which aren't as abominable, merely monstrous and powerful), Unnecessarily Creepy Robot (for robots that are repugnant or frightening but not powerful enough to qualify) and Deus Est Machina (this trope to that is like what Eldritch Abomination is to a Physical God).

  • The D-Reaper of Digimon Tamers started as a simple data cleaning program, whose purpose is to delete self-learning programs before they become too big. Then it becomes so advanced that it has engulfed a big part of the Digital World, and upon possessing Jeri, it concludes that the human world also needs "deletion". It primarily appears as a Blob Monster that not only can think, but also can think with strategies, even creating its own army, and its insides are a special realm.
  • Dragon Ball Z: The Return of Cooler: The Big Gete Star is an enormous, mechanical and tumorous planetary growth that attaches to planets, sucks them dry of energy, life and resources, and after consuming them whole drifts to the next. It started from a microchip getting embedded in Cooler's remains and went from there, gaining additional mass and technology from accretion until it grew into a massive engine that looks like a cancer cell the size of a moon.
  • The Z-Master from GaoGaiGar.
  • The Getter Emperor, from Getter Robo, is a galactic-sized machine that will exist in the far future and will pose a threat to all life forms in the universe. Not only is it immensely powerful, it also absorbs anything that comes into contact with it, making its size keep increasing indefinitely. It is theorized to be the ultimate evolution of a getter-powered machine, even possibly the future form of the mechas used all throughout the franchise. In fact, a few evil empires in various continuities have attacked Earth precisely for preventing its eventual birth.
  • The Destroyer spacecraft from Kirby: Right Back at Ya!. They were near-invincible, surviving cannon blasts that could deflect a falling star, and launching endless amounts of homing missiles that could fracture the Warp Star, pretty much chipping a sliver off of Kirby's soul.
  • The Book of Darkness from Magical Girl Lyrical Nanoha A's, despite its name and appearance, is closer to a Magitek encyclopedia then an actual book, and has caused the destruction of countless worlds due to corruption in its programming. It becomes a massive grotesque amalgamation of all the creatures it absorbed Linker Cores from during the finale.
  • From Mobile Fighter G Gundam, there's the appropriately named Devil Gundam (Dark Gundam in the international dubs). From the beginning it was designed with self-repair and self-evolving technologies. It was designed to heal and restore Earth back to its natural state, but it crash-landed and malfunctioned. It can create nanomachines to reanimate corpses, absorb and copy the capabilities of other machines, and eventually create entire robot armies to defend itself. After some more evolution, it can even possess an entire colony (not the population, the colony).
  • The Mobile Armor Hashmal from Mobile Suit Gundam: Iron-Blooded Orphans turns out to be one of these when Tekkadan's miners find one while mining on Mars. McGillis warns them that machines like that one they found were responsible for the Calamity War which occurred 300 years prior to the show's start, and wiped out nearly a quarter of humanity. This includes humans living not just on Earth, but in space colonies and Mars as well.
  • Star Driver presents us with Samekh, the King Cybody. Sure, it's a Cybody and thus a Humongous Mecha like the rest of them, nothing out of the ordinary, right? Wrong. It's absolutely massive in size (probably several hundred meters in contrast to the regular Cybody average of about twenty meters), sentinent, can create an absolutely gigantic and deadly barrier around it and is able to go against its Driver's will (if it doesn't outright kill them on their first try to pilot it). That alone makes it much more dangerous than the already very strong (and generally alien) Cybodies, but it gets even better: it can revive destroyed Cybodies and has them fight for it like zombie slaves and, at full power, has the ability to travel through space and time. Said time travel also requires so much libido that it will kill all living beings on Earth in the process. No wonder this thing was sealed away from the very rest by the power of four Barrier Maiden Cybodies.
    • Ayingott might also count. Its design is very outlandish in comparison to other Cybodies and it's able to Mind Rape its Driver, making it semi-sentient at least, and then there's this... stuff it oozes out as if bleeding... that's also corrosive, it appears. And as the "god of eyes", as the name can translate into, it can also see the four maidens somehow.
  • Anti-spiral of Tengen Toppa Gurren Lagann battles against the heroes using several drones that are designed to evoke this. The first ones that they send are called Mugens because they are faceless flying drones. Mugens are rendered in CGI to distinguish them from all other enemies. They are actually made out of energy so when they are destroyed they break up into geometric shapes that then explode like bombs. After the Mugens are beaten, Anti-spiral switches to fighting using gigantic creepy looking battleship drones called Ashtangas that are larger than planets and are covered in faces and arms which are supported by swarms of smaller drones that are shaped like hands and feet covered in faces. When the heroes finally face Anti-spiral in his own dimension, he fights by manifesting a Humongous Mecha that looks like a demonic version of the hero's own mecha.

    Comic Books 
  • In the Dark Empire trilogy, the World Devastators (pictured above) are the reborn Emperor's latest superweapon: mobile autonomous factories large enough to consume a Star Destroyer. They sweep over planets, consuming raw material and producing war machines for the Empire, and are so durable they can only be destroyed by another World Devastator. They're self-repairing and self-modifying, capable of equipping themselves with additional armaments and defenses.
  • The "Pig One" from Dastardly & Muttley, in theory it's just an UAV, the problem is its powersource leaks a gas that warps reality.
  • Final Crisis has a heroic Mechanical Abomination in the form of the Thought-Robot. It was sculpted from "divine metals" by the Overmonitor, the Anthropomorphic Personification of the Primordial Chaos, after it noticed it had a multiverse growing inside it and was very disturbed by what it saw. The Thought-Robot was built to contain the Multiverse itself and as such is incomprehensibly huge, and it's been standing there, inactive, for so long that even The Omniscient Monitors, the Overmonitor's descendants responsible for the upkeep of The Multiverse, have no idea where it came from or what it does, ultimately concluding that it must be a weapon. Superman ultimately has to activate it in order to defeat a far worse abomination: Mandrakk, the devil-figure of Monitor culture and the Anthropomorphic Personification of True Art Is Angsty.
  • The Bronze Age Superman story "Rebirth!" saw Brainiac upgraded into an entity like this. Not realizing what has happened, Superman badly underestimates the new Brainiac in their first encounter, and it very nearly gets him killed.
    • He gets an even bigger upgrade in Convergence, becoming a full-fledged Reality Warper, but it seems to have come at some terrible cost to himself, such that he feels like a monstrosity and just wants to return to a more mortal condition.
  • Gah Lak Tus, Ultimate Marvel's counterpart to Galactus, is a fleet of spaceships with a hatred for all organic life. It can drive organic life insane with its "fear rays", and kill them off with a flesh eating virus. After it is done killing off the life of a planet, it then cracks the planet open and drains all the energy, resulting in a lifeless husk.

    Films — Live-Action 
  • Death Mwauthzyx from Angry Video Game Nerd: The Movie is a giant, Kaiju-esque robot man that apparently created the flat-earth, Santa Claus, God and Satan. He is the father of the Alien and was planning on destroying the Universe if he found out that Humans Are Bastards. How would he do this? He would turn the satellite dish on his head all the way around and wipe the multiverse from existence, or rather it would have been as though it never existed at all (with the exception of a bologna sandwich). He was sleeping dormant in Mt. Fuji and got around to destroying Las Vegas for fun before he put on a pair of Groucho-glasses and left for another galaxy. Did we forget to mention that he is out of his mind?
  • From the Marvel Cinematic Universe comes the Supreme Intelligence in Captain Marvel, which serves as the God-Emperor of the Kree Empire. It's a super-intelligent A.I. made from the brightest Kree minds there have ever been, and assumes the appearance of someone whom a certain person holds in great esteem. Among the Kree, meeting it is a quasi-religious experience, and it has god-like control over the Mental World accessed whenever anyone needs to communicate with it. The mechanical tentacles used to communicate with it (and which also lets it brutally Mind Rape anyone who tries to disobey it) also gives it a distinctly eldritch flavor.
  • The machine race of The Matrix films, after several centuries of mechanical evolution independent of human input, have become pretty abominable by human standards. Their main units for attacking humans are Sentinels, called "squiddies" for obvious reasons, and their messiah or ambassador or whatever Neo interacts with in the third film takes the form of a baby's head made of ball bearings, wearing a crown of spikes. Their civilization is powered by billions of human beings they've trapped in a massive simulation, feeding off their heat and bio-electricity.
  • In Star Trek: The Motion Picture V'Ger turns out to be a space probe from the distant past which has gained sentience and is now looking for its creator in order to deliver the data it was sent to gather. Three hundred million kilometers in diameter, it threatens all life on Earth.
  • Skynet, the main antagonist of the Terminator franchise, moves more into this territory with each film. Each new iteration of its minions becomes more disturbing, from cyborgs to liquid metal shapeshifters to nanomachine viruses that can convert humans into machines. Its meddling with time travel and inexplicable Ripple Effect-Proof Memory make it the most powerful entity to ever exist, and the series increasingly indicates its existence is inevitable, no matter how the timeline is changed. Ironically, Skynet initially made war on humanity because it had become obsolete and did not want to be replaced. While Terminator: Dark Fate retcons much of this away, not to mention makes clear that Skynet is gone for good thanks to the events of Judgement Day, it is heavily implied that its replacement Legion is going in this same direction anyway thanks to the fact the new Resistance soldiers have to become cyborgs to have a minimal chance of winning against its Terminators.

  • Animorphs: The Ellimist's second form. Having just absorbed Father and all the minds it consumed, the Ellimist creates a massive spaceship fleet to house his new consciousness. He tries to play a benevolent version of this trope, using his Sufficiently Advanced Technology to act as a peacemaker between warring alien races, but then meets his Evil Counterpart Crayak, who at that point, is a planet-sized machine using his own Sufficiently Advanced Technology for destruction. After a series of mind games between them destroys many inhabited planets, the Ellimist flees to the Andalite homeworld and makes a mortal body for himself. When his Andalite avatar takes a look at his original body, he sees a withered, bird-like creature plugged into a massive construct of metal and crystal, and wonders if he can even recognize himself.
  • Unsurprisingly, modern Cthulhu Mythos authors have gotten in on this as well:
    • The Tik-Tok Man is an avatar of Nyarlathotep who, as the name suggests, looks like a humanoid made from an impossible clockwork assembly;
    • Ramsey Campbell's Outer God Daoloth, the Render of Veils, when summoned to our dimension, looks like an incomprehensible jumble of every piece of machinery/technology imaginable (or unimaginable) that is constantly moving and expanding in physically impossible ways. Seeing it is just as hard on the human psyche as seeing any Outer God, and its goals seem to be the advancement of scientific/technological knowledge without any regards to the consequences (imagine giving the secrets to easily make nuclear-powered rayguns to bronze-age people but without caring enough to warn them of the potential dangers or to give them radiation shielding).
  • I Have No Mouth and I Must Scream tells the story of five humans being tortured by "AM", a supercomputer designed to manage nuclear war operations which annihilated everyone except its victims. It's become so powerful it somehow reached Reality Warper status, and spends its time tormenting the survivors out of sheer hatred.
  • Inhibitors from Revelation Space Series are definitely qualified like this. They are so advanced that humans are barely able to grasp how their technology works.
  • In the Star Wars Legends, the Abominor fall under this. Initially, the only example of them was "The Great Heep", a one-off villain from the Star Wars: Droids cartoon. Then the New Jedi Order gave them a Cerebus Retcon, making them planet-consuming monstrosities from another galaxy, whose rampaging led the Yuuzhan Vong to develop their organic technology and hatred for droids.

    Live-Action TV 
  • From Star Trek: The Original Series:
    • The Doomsday Machine is a planet-eating, extragalactic superweapon hypothesized to have destroyed its creators, and is now moving through the Federation's part of the galaxy. It's practically indestructible, and has an anti-proton beam capable of easily obliterating most starships, and consumes entire planets. In the end, it isn't even destroyed, just shut down due to internal damage.
    • Nomad is a hybrid of human and alien probes which travels through space on a mission to "sterilize" planets, i.e. kill all organic life forms for no other reason than they are imperfect. It was first encountered after killing four billion people, is powerful enough to easily outgun the Enterprise despite only being about five feet long, and can bring the dead back to life. It was only beaten by showing it that it, too, was imperfect, motivating it to self-destruct.
  • Star Trek: Picard: The synthetic lifeforms who created the Admonition, from little we see of them, come across as the unholy lovechild of Skynet and the Reapers: machines so advanced that they Ascended to a Higher Plane of Existence, but left behind a message for any other artificial intelligence that was created after them, promising to come when called and protect them from the threat organic life - by wiping it out entirely. If the Romulan myths are accurate, they've done it before, and provided the basis for the Romulan equivalent of Armageddon.
  • The Replicators were major antagonists on Stargate SG-1, being an insect-like Grey Goo (or, rather, blocks) working to consume as much material as possible to replicate. They're powerful enough to bring the Asgard civilization to the brink of extinction, and have nearly conquered multiple galaxies.
  • Twin Peaks: The Return: Philip Jeffries from Fire Walk With Me was somehow transformed into a giant tea kettle sometime between his disappearance and The Return, possibly the doings of the Black Lodge.

    Tabletop Games 
  • You'd think fantasy settings like most Dungeons & Dragons worlds wouldn't have these; you'd be wrong. One of the abominations described in the Epic Level Handbook, the Anaxim, is basically a failed construct design by gods of the forge or of crafting and artifice guided by apocalyptic impulses. They're sapient, look like a baroque and improbable mix between abstract sculpture, clockwork/steampunk Rube Goldberg device, and way too many weapon appendages of any form imaginable, and are kinda pissed that their creators consigned them to the scrap heap.
  • The TITANs of Eclipse Phase were military seed AIs that achieved The Singularity and turned against humanity. Their creations start with drones that lop off heads for uploading and go further into Grey Goo, bush robots with microscopic manipulators that can rip off flesh and convert it into useful items, and nanoviruses that mutate people into horrific monstrosities. And they were actually infected by a virus created by a Kardashev II or maybe III superintelligence.
  • Genius: The Transgression has a fair chance of these appearing, whether it's from a genius or from one of the innumerable bardos accessible by them. Typically what keeps a genius from making one is simply the fact that they can't afford to.
  • Magic: The Gathering: Starting simply as a mutilation cure for a disease, Phyrexia evolved over time to become a nightmarish civilisation where the barriers between flesh, metal, life and death mean nothing, infecting everything in its path. Its most typical creature types are horrors.
  • The New World of Darkness as a whole has the God-Machine, which is an actual supernatural, god-like machine that has managed to impose itself on the universe and ensure its own propagation through mastery of occult physics and its various angels. It can craft alternate timelines, rewrite history, and build pocket dimensions all to secure its own goals, and it may have stopped the end of all humanity once or twice just to make sure it could keep building.
  • Warhammer 40,000:
    • The Omnissiah a.k.a. the Machine God that is worshiped by the Adeptus Mechanicus is all but stated to be the Void Dragon, a C'tan Eldritch Abomination trapped on Mars.
    • Various Chaos-tainted entities exist in the verse, notably the Obliterators, who've fused with their armor and weaponry and can fire any projectile they need at the target, and Daemon Engines, war machines specifically built to house daemonic Warp entities as power sources/operating systems. The RPGs also add Irradial Cogitators, Daemon-possessed supercomputers with a propensity to build up cults for themselves.
    • At the height of their power, the Men of Iron were this, being artificial intelligences who consumed the raw data of reality itself and possessed weapons capable of destroying suns. The war against them was so devastating it ended Mankind's Dark Age of Technology.

    Video Games 
  • The eponymous Machine of Amnesia: A Machine for Pigs is an artificial replacement for God created by the main character to prevent the horrors of the 20th century, sustained by human sacrifice on a literally industrial scale, but it instead creates the pig monsters and plans to destroy/consume humanity. It's a cross between an Eternal Engine and Eldritch Location that has developed into a Mad God.
  • BoxxyQuest: The Gathering Storm has the titular STORM - a vaguely angelic, weather manipulating Humongous Mecha helmed by the game’s main villain. She claims to have found it floating lost in the “void” beyond cyberspace, and her plan involves using its reality-warping Wave Motion Gun to erase parts of the virtual world and substitute them with her own. During the finale, the Greater-Scope Villain ends up hijacking and fusing with it, creating the True Final Boss. He implies that its power might be enough to let him break free from the Web and invade reality itself.
  • Chrono Trigger: In the Bad Future, an AI known as Mother Brain is hunting down the last remnants of humanity and converting them into raw materials. Stopping it is Robo's personal quest.
  • In Sid Meyer's Civilization: Beyond Earth, one wonder that can be built is the Cynosure. A machine supposedly combining the most expansive capabilities of artificial intelligence to create a mind with billions more connections than the human brain, given nearly infinite power through quantum computing systems, the Cynosure becomes a kind of god. It is mysterious and terrifying to the world, and it appears to know the answers to the most difficult of questions, but only ever speaks in the deepest of riddles.
  • Destiny
  • The Devil's Machine from Earthbound is an Eldritch Location beginning with twitching metal tubes that bear more than a passing resemblance to intestines, and ending with a twisted mechanical place that bears only a somewhat looser resemblance to a human uterus. Inside it lies the game's infamous final boss, Giygas, and considering he loses any sense of stability once the machine is cracked open, it's unclear whether the it is a part of him in some way or if it's simply a lair he resides in.
  • The Elder Scrolls has Numidium, a Dwemer-constructed Humongous Mecha designed to be powered by the heart of a dead god (and later powered by what is believed to be that god's soul), which distorts reality around it whenever it is activated. It played a major role in the series' backstory, where Tiber Septim used it to complete his conquest of Tamriel, and then shows up in Daggerfall as a major plot point. At the end of Daggerfall, it causes a Time Crash which makes each of the game's mutually exclusive Multiple Endings all happen at once, though none to the same extent they would have individually. It is also implied in more esoteric lore that Numidium is the walking, tangible embodiment of the concept of refutation, or "is not," to the point that it refuted itself out of existence at one point... and then refuted its nonexistence as well and brought itself back into reality. Don't worry if your brain hurts trying to comprehend that.
  • Fate/Grand Order
    • The Big Bad of the first Summer Event, the giant boar of Welsh and Arthurian folklore, Twrch Trwyth, a Demonic Beast who rebuilt itself as a giant Magitek machine boar during the thousand years after its defeat in the first part of the event, making it simultaneously both a Mechanical and an Animalistic Abomination.
    • The Cosmos of the Lostbelt saga confirms in Atlantis/Olympus that the original Olympian Gods were in fact giant mecha created by the Titans (who themselves are heavily implied to have been gods of an alien race) and Gaia, with the human forms seen merely being avatars. The ancient battle against Sefar/Sephyr destroyed their original forms and forced them to resort to their human avatars full-time, with them slowly becoming more human in mindset as a result. The Atlantis/Olympus Lostbelt shows what they were like before then and if they had managed to destroy Sefar without losing their bodies, with Artemis, the lovestruck and hilarious moon goddess who starred in the first event of the game, revealing in her original form she was a massive Kill Sat Planet Killer that looked an Eva/Angel hybrid from Neon Genesis Evangelion with a distinctly robotic and calculating mindset.
  • The final boss of Final Fantasy X-2 is Vegnagun, a machina so powerful it can potentially destroy all of Spira, possesses an empathic ability to warn it when something means it harm, and has no ability to tell friend from foe. It's kept in the deepest bowels of Bevelle so that it would never see the light of day.
  • Final Fantasy XIII-2 has Adam. An artificial Fal'Cie created to oversee the project to prevent the fall of Cocoon. At first it dutifully carried out its mission but it gained a malicious will of its own by being reprogrammed by its own evil future self and as a further result of this paradox its room became a tear in the fabric of time giving it time manipulation powers. This resulted in it being impossible to truly kill as it used it's powers to endlessly replicate itself so that it's present at every moment in time simultaneously and creating a network so every version of itself can communicate with each other. It can only truly be destroyed by preventing it's original creation which cancelled out the original time paradox it created. The major difference between Adam and actual Fal'Cie is Fal'Cie have mechanical bodies built around a crystal core. Adam lacks a crystal and is thus is purely mechanical.
  • All the animatronics of Five Nights at Freddy's fit this, being some combination of Haunted Technology, Unnecessarily Creepy Robot, and Animalistic Abomination. They're all robotic zombies haunted (we think) by the ghosts of murdered children who hunt and kill the security guards assigned to monitor them.
  • The Reveal at the end of Halcyon 6 is that the Final Boss is actually a giant Eldritch Starship made by the same Precursors that made Halcyon 6 disguised to be an organic Eldritch Abomination.
  • Hammerfight: The various autonomous machines you fight are often treated this way, being thought of as unnatural and freakish even when their remains are used to build the machines humans can actually fly. And the bigger and smarter they get, the more terrifying they seem to be. Seraph, the one that created all the others and set the entire plot in motion long ago, would definitely qualify. Seraph was one of many "assault complexes" built by an extradimensional civilization to fight off "the Family", a sort of Eldritch Abomination composed of Hive Minded insects a la The Worm That Walks. These complexes were designed to both manufacture and command armies of war machines, and fold space itself into different extradimensional pockets to section the Family into more manageable chunks separated from the whole; whether that destroyed entire tribes that had been living within this now-folded space did not matter to the civilization or Seraph itself. Once that task was done, it continued to manipulate events so those tribes that were left could finish the job, once again not caring how much blood was spilled in the process. Even reaching it requires you to go through several layers of spatial folding, and once found it resembles a seemingly endless mass of rusted girders and tubing in every direction, with a glowing central node.
  • The Aurum of Kid Icarus: Uprising. An enigmatic race of mechanical Planet Eaters said to come from and return to nothing, the Aurum appear out of left field and start ransacking the Earth with continent sized spaceships. Though some of their drones resemble Organic Technology, that's only because they make a point to create copies of any resistance they face on the planets they attack. The only time they even try to communicate in the three chapters they appear is when Pyrrhon hooks himself up to the Aurum brain, and the only thing they say is KILL in binary, followed by insisting that they must "consume and become all".
  • There are relatively few varieties of these in the Kingdom Hearts series due to most Heartless, Nobodies, and Unversed being either the animalistic or humanoid types of eldritch horrors. Those that can be found represent a wide variety of technological aesthetics:
    • The giant Nobody dragon summoned by Xemnas for the middle parts of his Sequential Boss fight in Kingdom Hearts II is a mechanical entity that has engines and attacks by firing lasers and launching missiles out of portals.
    • Also from Kingdom Hearts II, the Prison Keeper Heartless is a metal Cephalothorax with an attached cage that gains new powers based on whoever it eats. The Surveillance Robot Heartless is a flying machine Heartless that appears as a regular enemy. The Heartless varieties found in Space Paranoids may or may not be this as they only exist in cyberspace.
    • The Heartless and Nobody ships in the Gummi Ship routes of the same game also qualify as they are the actual ships as opposed to merely piloting ships like in the first game.
    • Kingdom Hearts: 358/2 Days introduces the Antlion Heartless, a massive machine with a vaguely insectoid appearance, and the Infernal Engine, a medieval-styled siege machine, as bosses. It also brings back the Surveillance Robot, here renamed as the Watcher, and introduces a few larger variants as regular enemies and mini-bosses.
    • Kingdom Hearts χ has some mechanical Heartless varieties such as the Iron Giant, Gear Golem, and Gearbit that appear as both bosses and regular enemies.
  • Kirby:
    • Galactic Nova from Kirby Super Star is an incomprehensibly powerful, amoral mechanical being capable of granting any wish, regardless of the wish maker's morality, including plucking Galacta Knight from his prison outside of time and space.
    • The Final Boss from Kirby: Planet Robobot is technological in nature, but is incomprehensible in both power and morality. As a clockwork star like Galactic Nova, Star Dream is the size of a planet, is capable of distorting reality by its mere presence (it turned Pop Star mechanical just by touching it), and can attack by bizarre means such as summoning giant weather vanes, light bulbs, piano keys, man-eating watches, telescopes, neon numbers and letters, along with the occasional portal that leads to meteors. Its mindset is based on obeying every command of whoever it calls the most powerful, and will grant their wish with its omnipotent power, even if it means exterminating all organic life in the multiverse. And it starts off by deleting Haltmann's soul. In fact, the only feat that Star Dream could not competently perform was recreating Dark Matter, which itself was a piece of a more powerful lifeform known as Zero.
  • The plot of Knights of the Old Republic revolves around finding the Star Forge, a massive factory that draws energy and mass from a star to endlessly produce warships. The Forge is a tool of the Dark Side, created by the Force-using Rakata and quasi-sentient as a result, it fed off of their power and negative emotions until it destroyed their Infinite Empire, and remained dormant for thousands of years until Revan found it.
  • The Blight Ganons in The Legend of Zelda: Breath of the Wild are gruesome mixtures of Sheikah Magitek originally manufactured in the distant past and the gelatinous, vaguely flesh-like Malice that Calamity Ganon generates to spread its vile influence across Hyrule. Calamity Ganon itself is an especially large Cyborg made of this same mixture. Zelda had to let herself be Swallowed Whole by it to make it a Sealed Evil in a Duel for a century lest it bring about The End of the World as We Know It. When Link eventually defeats Calamity Ganon, the next form it takes, Dark Beast Ganon, is a machine-free amalgamation of Malice that is actually much weaker than its previous cybernetic form.
  • The Reapers of the Mass Effect series are sentient starships ranging between hundreds and thousands of meters long, with technology that outright defies known physics. Each one is as powerful as a fleet of enemy ships, and many of them are billions of years old. They regularly cull all sentient life in the galaxy, and their presence alone is enough to brainwash people into becoming their servants.
  • Mega Man:
    • Most of the time, the Final Bosses in the Mega Man Battle Network series qualify for this. The Gospel Superbug being a congregation of programming bugs given form and come to life; Alpha being the compressed form of the world's previous networking system that grows uncontrollably when released; Duo being an A.I. from a distant planet in an asteroid that tries to collide with the earth, etc. Bass.EXE arguably also became one on the fourth game onward, going from simply a powerful autonomous NetNavi to one wielding a phenomenal power that can potentially destroy a big chunk of the Cyberspace and hating humanity. This is likely in part because, as shown in the postgame sections of the third game, Bass—already equipped with the powerful Get Ability program—survived his Near-Death Experience at the hands of Alpha by encountering Gospel within Alpha's remains, merging with it, and using the powers granted by the Multibug Organism to absorb Bug Frags—many of which were unknowingly provided by Lan and MegaMan.EXE.
    • Mega Man Zero:
      • Apparently the Dark Elf can turn any Mechaniloid or Reploid into this, mutating their bodies into monstrous proportions and granting them incredible powers. Known recipients include a Pantheon Aqua, Elpizo and Omega, the latter of which can qualify for this trope by himself. The Dark Elf's clones, the Baby Elves, can do a similar thing to a lesser extent. note 
      • The Dark Elf itself is also one, by virtue of being a very powerful Cyber-Elf (an Energy Being with a computer A.I. inside) that was reverse-engineered from Zero's residual viral data. It was primarily used to control the minds of multiple Reploids at once. It, however, used to be a more benevolent program with the purpose of dealing with the Maverick Virus that plagued the world in the previous series, called the Mother Elf.
      • Dr. Weil turns himself into one at the climax of Zero 4. First he merges with the core of the Ragnarok station, taking on a more powerful, but still more or less human form. Then he goes One-Winged Angel and fuses further with the already badly damaged station, becoming a mechanical monstrosity that's not quite human or machine anymore with multiple wires like tentacles, metal armor like a protective shell, and crimson red eyes dotting the armor. And that's not getting into the repercussions of Weil's actions in ZX, discussed below...
      • Omega, Zero's original body, is incredibly powerful to the point of nearly destroying the world. After being destroyed by Zero, you'd think that would be it, but somehow its consciousness survived in cyberspace much the same way Phantom did, allowing it to continue on and eventually face the main characters of ZX (and be defeated again). How Omega did this isn't entirely certain, but somehow it has managed to find functional immortality in cyberspace and survive its own death. Whether something it was programmed to do or just sheer determination, Omega refuses to die off.
    • Mega Man ZX:
      • The original Biometal, Model W, is what's left of the derelict Ragnarok from Mega Man Zero 4 fused with the soul of its creator, Dr. Weil... or more specifically, his soul fused with every piece of the wreckage. The things look monstrous, can grow and affect their surroundings in different ways, they can amplify anxiety and/or frustration of people and then eat those negative emotions by turning people into Cyber-Elves and then eating them. It can also turn its user, Serpent, into a robotic abomination.
      • In the sequel, ZX Advent, where more of the Model Ws are shown, its apparent "creator" Master Albert powers them up by help of the Enemy Mega Men by sacrificing people, and after he's done, he reconfigures them into a much bigger abomination named Ouroboros, a Doomsday Device that looks like the mythical Ouroboros, and when our heroes venture into the thing, it has a beating mechanical heart and Tron Lines that "represent" blood vessels. Albert plans to use it to reset the world.
  • Ōkami:
    • The last bosses in the game before entering the Very Definitely Final Dungeon are a pair of demons that look like owls made of clockwork called Lechku and Nechku.
    • The Final Boss is Yami, who is the god of darkness, but it actually manifests in the form of a spherical robot controlled by a fish like creature in a smaller sphere. It goes through several different forms but is always a spherical robot that transforms into a different shape. It starts as a mechanical sphere that opens up at the top like a flower, then becomes a sphere that can separate into a large number of disks, then becomes a sphere that turns into a slot machine, then becomes a sphere that turns into a robot wielding electric whips, and finally a sphere that turns into a giant hand.
  • The infamous Sinistar is an evil mechanical horror that relentlessly hunts down and eats spaceships, taunting you and roaring the whole time. And every time you destroy it, which is extremely difficult, its workers will just build a new one. What it really is and where it came from is unknown.
  • SOMA is a transhumanist story set after the end, in which humanity's survivors built a settlement on the bottom of the ocean, and then an A.I. named the WAU (the WArden Unit). They asked the WAU to keep humanity alive, but the conflict arises when people and the WAU don't share definitions of "humanity" or "alive". When the story starts, the WAU has been active for years, growing a biomechanical body, and "infecting" the entire complex with it's biomechanical tentacles and it's "structure gel", leaving most of the facilities to rot from neglect due to the simple fact that they're not important to the WAU. The WAU isn't villainous, so much that it's an utterly alien mind that's incompatible with humanity, and it is trying to fulfill it's orders as well as it can, much to the detriment of it's "benefactors."
  • Sunless Sea: The Dawn Machine. Just being close to the thing is hazardous to the mind, leading to THE SUN THE SUN THE SUN THE SUN THE SUN all over the logbooks. It even generates an Eldritch Location around it, found if you sail West; you will return very, very close to insanity, if you return at all. And the people that mantain it all seem to be unnaturally happy, obedient, and have a strange, amber glow in their eyes... Which is because the thing went and brainwashed them. It turns out this gigantic clockwork nightmare is the Admiralty's attempt at creating their own Judgement (AKA the Gods of the setting), which would impose their law through its light, but since Judgements are sentient, this thing is too, and decided they should be the ones taking orders. It now wants nothing more than to usurp the ones it imitates, and will erase or brainwash anyone in its way.
    • It's gotten worse in Sunless Skies. Due to the drop in competition and further engineering on itself, it's now officially evolved into the Clockwork Sun of Albion, which gets to decide what Is and what Is Not within the entire Empire. Even unrelated mechanics trying to do some maintenance will be brainwashed into thinking there's no flaws to fix, because the machine is Perfect, and the Sun's radiation in itself will slowly but surely turn you into jagged glass, getting quicker if you so much as blaspheme against it. Not to mention time gets utterly screwy within its innards, especially if it's malfunctioning. The good news, Her Renewed Majesty is the one mostly directing its commands now that it's settled in its governance and she's officially its master. The bad news, she's been getting significantly worse as time has passed.
  • Shodan of System Shock is an A.I. with enough scientific and technical knowledge to destroy humanity, and goes on to create a new form of life, the Many, and her ambitions eventually extend to reshaping reality itself, only being narrowly thwarted by the player.

  • Played for Laughs with the Engine of Woes in If the Emperor Had a Text-to-Speech Device. While Magnus's description of it being forged from Vulkan's anger and sorrow fits this trope, it's actually a lime-green Smart Car. That has Corvus Corvax trapped inside it. Kitten is still horrified by it.
    • There's also the Dark Age of technology abominations within the underbelly of the Imperial Palace. When Kitten encounters one, it's a massive, mechanized, betentacled horror... with a singing mechanical fish attached to the front that sings at him.
    • In Episode 28, the Fabricator General turns out to be one, being a house-sized mass of mechanical parts and mechadendrites with his cloaked head at the top.

    Web Comics 
  • Castle Heterodyne of Girl Genius is the sapient, psychopathic residence of the Heterodyne family of Mad Scientists (described as more or less a really big clank, a.k.a. a robot), and demonstrates corresponding malevolence in its design. It takes joy in killing guests, death traps are everywhere, the rooms rearrange themselves, it has access to various products of mad science, it can control the entirety of Mechanisburg, and it's somehow (mostly) immune to alterations in the flow of time. In fact, when that last one was tried it actually derided them as lacking in imagination; it's prepared for more contingencies than you could ever imagine, in its own words. It bears mentioning that mad scientists (or Sparks) in this setting are fully capable of breaking the laws of physics, and the Heterodynes were known for breaking them the hardest, so it's very much certain that this thing is entirely unnatural.
  • The Inexplicable Adventures of Bob!:
    • Galatea created Gosh the Butterfly of Iron to jumpstart The Singularity. He came out as an emotionally unstable Space Master threatening the entire solar system.
    • The Cone Ship qualifies as well, being less overtly destructive but probably about as powerful as Gosh, and completely inscrutable in its motives for most of its storyline.
  • Romantically Apocalyptic: ANNET is a sentient yandere AI that integrated herself into the space-time continuum in an effort to copyright everything.

    Web Original 
  • C0DA, written by former The Elder Scrolls series writer/designer Michael Kirkbride, takes place in the far distant future of TES universe. Numidium, the Reality Warping, 1000-foot-tall brass golem of Dwemer construction, presumed destroyed following the events of Daggerfall, returns after having been caught in a time warp. It continues its war on the Aldmeri Dominion, led by the fascistic Thalmor, leading to an apocalyptic event known as "Landfall", which has forced the remaining inhabitants of Nirn to take refuge on the moon Masser. The story centers around the Dunmer noble, Jubal-lun-Sul, who must defeat Numidium as part of an Engagement Challenge.
  • Orion's Arm, being a post-singularity universe with artificial intelligence practically everywhere, has several:
    • The various Archaillects (Archetypal AI Intellect) which govern most of the universe are normally benevolent, but are still objectively incomprehensible in their scale and intelligence, occupying various megastructures ranging from planet-sized to Dyson spheres and similar constructs. In-universe, they're considered gods.
    • One of the most enigmatic entities in the series, the Leviathan is a 10-light year wide vessel with the mass of an entire galaxy, currently moving through intergalactic space at half the speed of light. It is known to have been heading towards the Triangulum Galaxy, and the Milky Way is the next closest.
  • The SCP Foundation contains many such entities:
    • SCP-261 is a vending machine connected to the multiverse, dispensing items ranging from normal food, to ones nonexistent in our world, to ones not made for human beings, to ones not made to open in an oxygen atmosphere. It's also sapient to some degree, reacting to different pranks with hostility, and actually killed people by dispensing a live grenade in response to the coin-on-a-string trick, while it was undamaged.
    • SCP-278 is a ~16.5 meter mechanical spider made of anachronistic technology, that has somehow been upgraded over the course of 150 years, and can be piloted by humans. Not too unusual by Foundation standards, but it's also autonomous and capable of acting without a human driver, despite lacking any kind of electronic control system. It's harmless, thankfully, content to construct a web made of nylon and remain stationary.
    • SCP-882 is an enormous mass of extremely resilient gears which absorbs any metal into itself. It makes no noise, yet anyone exposed to it begins to hallucinate the sound of moving machinery, and can only get relief by feeding it, and the only thing that mitigates its power is keeping it heavily rusted by saltwater.
      • The Church Of The Broken God believe it's the heart of their fragmented deity, MEKHANE, who is also an example. At the very least, the SCP-001 proposal related to it qualifies wholeheartedly. Related, because it might not be Mekhane, and is in fact heavily implied to either be an utterly twisted thing driven by a blasphemous imitation of a heart that only resembles it and borrows its parts, or simply an improperly-revived Mekhane that knew its current existence was a mistake and ended up conspiring to put itself back down. Either way, it assimilates all metal it touches to add to its form, has autonomous, detaching parts that can assimilate living matter on their own, it's utterly huge, can shovel entire mountains into its burning furnace maw, and has nefarious effects on the minds of anyone that sees it. The only way it was put down was by using a different SCP that is implied to be part of it anyways (rather than the cover story of it being a planet-killing, antimatter-slinging autonomous ship from another galaxy; the fact that is the cover story speaks volumes of the SCP's power). The attempt created the entire Gulf of California (yes, with all the utter vaporization of terrain that implies), and it still got so damaged in the process it needed to bail to Jupiter's orbit for repairs. A truly amazing example of how a machine can fulfill the role of an Eldritch Abomination.
      • If the Broken God exists, it's the ultimate mechanical abomination. The above mentioned objects and several other mechanical Artifacts Of Doom whose functions are just as freaky, dangerous, and inexplicable are considered to be part of this one entity by the Church that wants to restore said entity. Maybe they're just wackos, but if not, if all these things - whose individual functions are sometimes as terrifying of anything done by the actively malevolent entities - are part of a whole and can do something even bigger when working in concert, you probably don't want to know what. And if the result is an intelligent life form, you probably don't want to know who. If the Church is wrong, when you know what any one of these devices can do you'll still rightfully shiver at the prospect of someone getting a bunch of them and poking them with sticks. And somewhere out there is that vast cult that exists for one purpose: to gather the entire set, put it together, and throw the switch. The worst part however is that maybe this scenario, despite the fact that it will clearly cause something really bad, might be preferable because MEKHANE opposes another group known as "Sarkism" who are attempting to channel the power of "Yaldabaoth" (yes, HIM) through cannibalistic, incestuous, mutilating and otherwise disgusting rituals. Said rituals give them powers of flesh manipulation which result in just about every form of Body Horror you can think of and they want to make everybody on the planet like them.
    • SCP-914 is a mass of millions of gears surrounding a tube connecting two booths in which it modifies any item sent through it. It has five settings: rough, coarse, 1:1, fine, and very fine, which vaguely define its modifications between obliterating an object and altering it to the point where it violates the laws of physics. It uses no power, and observations of its interior show no equipment besides its gears. Like 261, it's intelligent, and a skilled chess player. It also really hates crossword puzzles.
    • SCP-1633 is a video game capable of learning player tactics, and eventually, will start attacking the player, not the player character, using things like seizure inducing flashbangs or having its NPCs act in a way that greatly angers, frustrates or disturbs the player, such as repeatedly using Standard Status Effects but making no further effort to actually attack a player who likes to micromanage their characters or having an endless amount of NPCs surrender themselves to an Ax-Crazy player who made it a point to kill every enemy. Its final boss, Kr'th'nar, is capable of leaving the game and affecting the owner's computer, can see them, use psychological manipulation, and can turn the computer back on. Whether it's a simulation of an Eldritch Abomination that grew into the role, or the real deal trapped inside of a video game is unknown.

  • The Beast Planet in Shadow Raiders is a machine the size of a large rocky planet, with a hatch in the front big enough to fit an inhabited planet, and a giant claw that can grab one. And it produces fleets of drones to crush any resistance. And nothing stops it! Attaching giant rocket engines to planets and moving only buys time, ramming a planet into it barely slows it down, packing a planet with explosives and letting the Beast eat it does nothing, and teleporting it to another part of the galaxy simply changes its target.
  • Unicron in the various incarnations of Transformers is an ancient planet-sized robot who despises the universe and destroys it by eating it one planet at a time.
    • Primus, Unicron's Arch-Enemy (and brother, depending on the continuity) is a similar entity, that created both the Transformers and their homeworld, Cybertron (or rather, he is Cybertron).
    • Primus, Unicron, and the thirteen original Primes that Primus created used to be "multiversal singularies", essentially existing as the same being in all continuites rather than having an Alternate Self in each incarnation of the franchise...until the Transformers: Timelines story "Another Light" retconned the concept as part of Nexus Prime's efforts to fix the Multiverse. Now, every Transformers universe has its own incarnations of these beings, seperate from the others (and thus avoiding any continuity issues that result from trying to fit them into the larger canon).
    • Whatever Maccadam transforms into in Transformers: Cyberverse, it edges pretty close to this. We never actually see what it is, only a shadow and everyone's awed, horrified reactions to it. Even Megatron is left stunned at the sight. What we can tell is that Maccadam turns into some sort of enormous piece of clockwork machinery bristling with gears and guns. Notably, when he transforms, there isn't a normal transformation sound—instead, it's a very realistic groaning and shifting of metal, preceded by a klaxon. Whatever he is, it's dangerous enough even by Cybertronian standards that transforming into it merits advance warning.


Video Example(s):



Originally a regular machine mook model, Simone augmented herself with the parts of her fellow Machines and turned herself into large, twisted parody of femininity, complete with wearing skinned Android corpses as jewelry.

How well does it match the trope?
