History Main / MechanicalMonster

* ''Franchise/MassEffect'': Reapers go a bit beyond this into MechanicalAbomination, but they'd have to count the few times you fight one on foot -- most notably Priority: Rannoch, which famously involves syncing up a target pointer to the biggest fleet in the galaxy and having them rain Thanix projectiles on its weak point. It takes one hell of a pounding to down it, and it's the ''smallest'' type of Reaper -- a mere 160 meters tall[[note]]the same height as [[https://commons.wikimedia.org/wiki/Category:160-meter-tall_buildings all of these tower blocks]][[/note]], unlike its two-kilometer long siblings.

* ''Manga/OnePiece'': The Pacifistas. These guys are made of an incredibly hard material, making them NighInvulnerable to typical physical attacks, possess [[EnergyWeapon Frickin' Laser Beams]] in a story that presumably takes place in the [[AnachronismStew 15th century]], and share the appearance and physical strength of [[BearsAreBadNews Bartholomew Kuma]], one of [[TheDreaded the most feared men in the One Piece world.]] It's said that one of these things is the equivalent of a ''battleship'', and it took all of the main characters working together with everything they had to beat a single one pre-Time Skip. Double Subverted after said TimeSkip. Two Pacifistas fall victim to TheWorfEffect to demonstrate how powerful the Straw Hats are now, [[CurbstompBattle proving to be absolutely no challenge for them anymore]]. However, immediately after that, it's been stated that there are far more powerful Pacifista out there now, although they haven't been shown nor has it been stated exactly what's improved over the originals.

* The manga ''Manga/SeiketsuNoHagurama'' has a literal blue-blooded prince and GadgeteerGenius construct SteamPunk looking machines like a [[http://www.mangahere.com/manga/seiketsu_no_haguruma/c001.1/16.html whale-shaped ship]] and a [[http://www.mangahere.com/manga/seiketsu_no_haguruma/c001.2/22.html pilot-ridden steam blowing minotaur]] whom he thought were being used for peaceful purposes (but were actually used to eradicate the remaining red-blooded people by his father and king).

* ''ComicBook/FantasticFour'': Doctor Doom had one, [[http://marvel.wikia.com/Doomsman_II_(Earth-616) The Doomsman]].

* ''Series/SpiderManJapan'': A very early example of this trope in live action television appears here, where the MonstersOfTheWeek are called the Machine [=BEMs=].
* ''Franchise/SuperSentai'': Whenever the enemy group is mechanical in nature, there is a high chance the MonstersOfTheWeek they employ are this trope. Examples are the Machine Beasts of ''Series/ChourikiSentaiOhranger'' (adapted into Machine Empire monsters in ''Series/PowerRangersZeo''), the Barbaric Machine Beasts of ''Series/EngineSentaiGoOnger'' (adapted into the Venjix Attack Bots in ''Series/PowerRangersRPM'') and the Metaroids of ''Series/TokumeiSentaiGobusters'' (adapted into the Robotrons in ''Series/PowerRangersBeastMorphers'').

* When they were still a legion and had their primarch Lion running around, the Dark Angels had the Ironwing company which specialized in war engines. If things got ugly, sometimes they'd bring out the Excindio-class Battle Automata which are powerful and vicious robots. Being a mechanical monster is a step down for these machines as they were previously part of the [[MechanicalAbomination Silica Animus that nearly destroyed humanity]].

While mecha-mooks are often fragile, incompetent, and generally gentle at their jobs, expect the Mechanical Monster to be far less kind to its prey. Slashing, stabbing, soul stealing to fuel their infernal engines, and [[ArsonMurderAndJaywalking loud noises]] are all par for the course. Lastly, in extreme cases, it may also be much bigger size-wise than a standard mecha-mook, with some even doubling as HumongousMecha opponents.

* ''[=Mazinger=]'':
** The MonsterOfTheWeek MechaMooks in ''Anime/MazingerZ'' are called "Kikaijuu", which is made of the words for "machine" and "monster" in Japanese.
** And then you have the Mykene War Beasts ("Sentoujuu") in ''Anime/GreatMazinger'', Mykene soldiers grafted into gigantic mechanical bodies. They had shape of humanoid warrior, evil spirit, mammal, bird, reptile, fish or insect.
** The Saucer Beasts and Vega Monsters from ''Anime/UFORoboGrendizer''. They are animalistic mechanical monsters resemble flying saucers pre-transformation.

** ''Shin Getter Robot'' is a rare heroic example, at least in the original manga arcs (Its more monsterish aspects get ''severely'' toned down in other appearances such as [[VideoGame/SuperRobotWars SRW]] or the getter OVAS)
** Mechasauruses and Mecha Oni play it straight, though: the former ones are robotical dinosaurs, and the seconds are horned, demonic-looking mechanical beasts.
* ''Anime/RobotRomanceTrilogy'': The standard MonsterOfTheWeek:
** The bio-mechanical Slave Monsters and Magma Beasts from ''Anime/CombattlerV''
** The Beast Fighters and later Super Beast Fighters from ''Anime/VoltesV'', resembling robotical Earth animals.
** The Battle Robots and Mecha Warriors from ''Anime/{{Daimos}}''.
%%* ''Anime/Zambot3'': The Mecha Boosts.
* ''Anime/Daitarn3'': The Megaborgs, although they start out as less-monstrous Meganoids before mutating themselves.

* ''Manga/Reborn2004'': Gola Mosca. It is powered by [[spoiler: the LifeEnergy of the Ninth Vongola Boss]].
* ''Anime/{{Kakurenbo}}'': The "oni", which resemble giant animatronic puppets.
* The manga "Manga/SeiketsuNoHagurama" has a literal blue-blooded prince and GadgeteerGenius construct SteamPunk looking machines like a [[http://www.mangahere.com/manga/seiketsu_no_haguruma/c001.1/16.html whale-shaped ship]] and a [[http://www.mangahere.com/manga/seiketsu_no_haguruma/c001.2/22.html pilot-ridden steam blowing minotaur]] whom he thought were being used for peaceful purposes (but were actually used to eradicate the remaining red-blooded people by his father and king).

* ''Anime/{{Voltron}}'': Nearly every episode of the American translations -- both for the lion-team Voltron and the vehicle-team Voltron -- culminates in a fight against a giant enemy [=RoBeast=]. Once or twice on the vehicle-team Voltron show, these robotic engines of destruction are shown with normal-sized pilots inside. (Since this was a NeverSayDie translation, the pilots were themselves android stormtroopers.)

[[folder:Card Games]]
* ''TabletopGame/MagicTheGathering'': Some of the more impressive artifact creatures easily qualify as this rather than the standard MechaMooks of dragon engines and myr. The main villains of the series, the Phyrexians, have the purpose in life of turning all living things in existence into this, and are themselves a collection of nightmarish, twisted biomechanical monstrosities.
[[/folder]]

* ComicBook/{{Batman}} has a robot dinosaur in the TrophyRoom of the Batcave; a souvenir of a case called "Dinosaur Island".
* In Creator/MarvelComics's [[MerchandiseDriven toy tie-in]] comic ''The Toys/{{Starriors}},'' the title characters are about evenly split between semi-humanoid robots and animal and dinosaur-shaped ones. They're all perfectly sentient.

* ''ComicBook/TheTransformersMarvel'' features the Guardian Units, which are bright yellow, ridiculously huge by Cybertronian standards, and have a distressing tendency to turn against their owners. They are also incredibly over-powered and very strong, to the extent that even one of them is enough to give [[BigGood Optimus Prime]] trouble. They reappear in ''ComicBook/TransformersMoreThanMeetsTheEye'', where an army of them is sent up against Overlord, [[TheWorfEffect who quickly ploughs through them]].

* ''WesternAnimation/DragonRider'' The Villianous metal Dragon-eating monster Nettlebrand.

* ''WesternAnimation/{{Nine}}'': The villains fit the bill, being a collection of animal-like robots sent to hunt down and destroy the protagonists, and all of them are appropriately horrific. The Big Bad, [[BuffySpeak the huge, multi-armed artificial brain thing]], ''DEFINITELY'' fits the bill.
* ''WesternAnimation/AtlantisTheLostEmpire'': The Leviathan is a {{Magitek}} version of this, somewhere in the vicinity of a ''couple miles long'', [[PerpetualMotionMonster capable of staying intact without recharging for thousands of years]], [[TheJuggernaut immune to direct torpedo hits]] and equipped with shearing claws and a particle beam-like BreathWeapon. Only one of them still functions by the time the heroes arrive at the gateway to Atlantis -- there used to be an entire fleet of them back in Atlantis' heyday that had the ability to fly as well-- but it's more than enough to trash their sub and kill over a hundred people.

* ''Film/HellboyIITheGoldenArmy'': The title Golden Army. Saved from being simple mecha-mooks by their sheer hardiness. And a [[PullingThemselvesTogether self-repair function]].
* The giant Harvester from ''Film/TerminatorSalvation'' would most definitely count, as would the semi-humanoid tanks from the earlier movies.
* ''Franchise/{{Godzilla}}'': The original Showa-era [[EvilKnockoff Mecha-Godzilla]] was a vicious alien robot built with the intent of first discrediting, and then killing Godzilla. Powerful enough to battle Godzilla and King Caesar at the same time, the robot proved a match for anything that the more heroic kaiju could throw at it.

* In ''Film/RedSonja'', the bad guys unleash a killing machine in the form of a robotic alligator. It's completely invulnerable to the heroes' weapons, except for the eyes, which they manage to carve out while its thrashing about.

* ''Film/DeathMachine'': The Warbeast is essentially a ten-foot tall, nigh-invulnerable collection of hydraulics, claws, and teeth. Given that it's creator was very much a MadScientist and it's official role would be a "Frontline Morale Destroyer", it's intentional.

* Franchise/StarWarsLegends:

* ''Series/ThePrisoner1967'': If the smoke monster counts, then its grandfather Rover deserves a mention too. It's a white floating plastic sphere, and acts as a security device for the Village, but it's also ''alive'' somehow; it roars and groans and has a mind of its own, even killing the wrong person once. Rover was originally a more straight [[http://en.wikipedia.org/wiki/Rover_%28The_Prisoner%29 robotic example]] of the trope, until the prop [[SpecialEffectFailure sank in the waters off Portmeirion]] during the initial stages of filming.[[note]]Actually the wikipedia page confirms that story is apocryphal; the robotic version just didn't work very well.[[/note]]

* ''Series/SpiderManJapan'': A very early example of this trope in live action television appears here, where the MonstersOfTheWeek are called the Machine [=BEMs=].
* ''Series/DoctorWho'': The Raston Warrior Robot in "The Five Doctors". Built as the ultimate killing machine, a single one is able to destroy an entire squad of Cyberman without taking a scratch in return.
* ''Series/KamenRiderDrive'' has [[MonsterOfTheWeek Advanced Roidmudes]], the forms taken by [[KillerRobot Roidmudes]] who've successfully evolved through use of a Viral Core, granting them a monstrous form and special powers.
* ''Series/KamenRiderRyuki'' and ''Series/KamenRiderDragonKnight'' has the vicious MirrorMonster[=s=] of the supernatural variety.

* ''TabletopGame/DungeonsAndDragons'': There are several [[CallARabbitASmeerp "constructs"]] that fit this category, most notably the Hellfire Engine, a GiantMecha made out of cold iron and powered by (as well as shooting) hellfire and the Anaxim, basically the twisted mechanical abortion produced by a god of the forge getting a little too crazy.
* ''TabletopGame/IronKingdoms'': Warjacks are large (seven to twelve feet tall) steam-powered robots used to protect and assist the setting's Not-So-{{Squishy Wizard}}s. 'Jacking is a form of capital punishment in some countries and, if that wasn't bad enough, the ''WARMACHINE'' {{wargam|ing}}e introduced [[NamesToRunAwayFromReallyFast Deathjack]], a semi-autonomous Orgoth warjack powered by ''souls.''
* ''TabletopGame/GammaWorld'': Whenever you want to tell your players to [[ThatOneBoss go f*** themselves]] in your game, you use the [[ExactlyWhatItSaysOnTheTin Death Machine]], the setting's [[OhCrap mechanical equivalent to the]] [[TabletopGame/DungeonsAndDragons Tarrasque]].
* ''TabletopGame/{{Exalted}}'' has its fair share of these, such as the Thousand-Forged Dragons and the Brass Leviathan.
* ''TabletopGame/FabulaUltima'': The Razorbird is a large {{Magitek}} construct resembling an enormous bird of prey. It has razor-sharp feathers with which to make melee attacks and an arsenal comparable to that of a real-world fighter jet, complete with missiles and gatling guns. Militant empires often make use of these machines in their air forces.

%%* ''VideoGame/PuzzleAndDragons'': Some of the monsters , especially the higher-level monsters, are definitely this.%%How?
* The Deimos of ''VideoGame/ThirteenSentinelsAegisRim'' certainly fit the description, with them being aggressive {{kaiju}}-like robots with a [[RedAndBlackAndEvilAllOver red and black color scheme]] and [[GlowingMechanicalEyes glowing]] [[RedEyesTakeWarning red eyes]]. Strangely enough, [[spoiler: they are revealed to be construction equipment. Why they are such [[UnnecessarilyCreepyRobot Unnecessarily Creepy Robots]] is anyone's guest.]]
* ''VideoGame/{{Crysis}}'': The alien Hunter. It's a house-sized HumongousMecha with a decidedly inhuman design (looking more like a deep-sea [[GiantEnemyCrab crustacean]]), bristling with {{Freeze Ray}}s and {{Wave Motion Gun}}s. It also has several moving parts on its front, which seem to be there only because they look threatening. Also, it can ''roar''.

%%* ''VideoGame/ChronoTrigger'': The ROB line could be a good example of these. Also, Lavos' core seemed very Mecha-esque.
* ''VideoGame/MegaManClassic'', being a robot-based series, has its share of these, mostly as Wily Fortress bosses, most notably [[ThatOneBoss The Yellow Devil]] and all the other Devil series robots.
* ''Franchise/FinalFantasy'': [[{{Superboss}} Omega Weapon]] from is often depicted as this. Other times he's a ''bio''-mechanical monster. The very first ''VideoGame/FinalFantasy'' has fellow {{Superboss}} [[BossInMookClothing in mook clothing]] Warmech, an extremely durable, regenerating, nuke-tossing monstrosity with a DeathRay.
* ''VideoGame/CastlevaniaLordsOfShadow'' has a giant robot scorpion BrainInAJar built by Doctor Frankenstein.
* ''VideoGame/AgentUSA'': The [=FuzzBomb=] from used to be a normal television set, until an experiment GoneHorriblyWrong gave it malevolent sentience (with angry eyes!), and it's now trying to turn everyone in the entire United States into mindless, walking TV static.
* ''VideoGame/MetalSlug 2/X'': Most players wouldn't know what the second boss ([[http://metalslug.wikia.com/wiki/Aeshi_Nero Aeshi Nero]]) is when they first see it. It's a gigantic excavator robot designed to look like a cobra.
* ''VideoGame/MetalGearSolid4GunsOfThePatriots'': The Gekko are as much life-form as machine; they're about as smart as an animal, make appropriate sounds when they're in distress, and, of course, have organic legs. They also follow the basic use of the Mechanical Monster trope in that they are much more dangerous and intimidating than a simple robot would be.

* ''VideoGame/MiniRobotWars'': The Frost Orca is a large, whale-submarine bot that spits out deadly ice balls, has a TON of health, is more tenacious than the regular mooks, and acts as a BossInMookClothing. [[ArsonMurderAndJaywalking It also practices good dental hygiene]].

* ''VideoGame/QuakeIV'': The Harvester {{Spider Tank}}s seem to be partially organic like the aforementioned Scarabs, by the sounds they make. They're easily the most threatening Strogg faced by Kane, being a MiniBoss when on a vehicle and when on foot, an obstacle to be evaded instead of an enemy to be fought.
* ''VideoGame/WonderBoy'': The Meka Dragon.
* ''VideoGame/{{Descent}} 3'' has the Homunculus, which looks like a mechanical version of the Rancor from ''Film/ReturnOfTheJedi''.
* ''VideoGame/XenobladeChronicles1'': The Mechon are all walking machines of death and mayhem, but they couldn't be called monsters, at least not individually. The faced Mechon, however, are the ones who could be called monsters [[spoiler:[[ManInTheMachine but they aren't really machines]].]]
* ''VideoGame/XenobladeChroniclesX'' has various large, mechanoid Tyrants across the continent of Cauldros. Among them is Leva'el the Terminus, a {{Superboss}} that only appears in the PlayableEpilogue.
* ''Videogame/SimCity4'': The Autosaurus Wrecks is basically a ''T. rex'' (or perhaps Franchise/{{Godzilla}}) made of cars, which when summoned rampages around wrecking everything it finds.
* ''VideoGame/SlyCooperThievesInTime'': The Moat Monster, one of the Black Knight's twisted inventions.
* ''VideoGame/ShantaeAndThePiratesCurse'' has the Steel Maggot ([[BossSubtitles Patent Pending]]), a giant, [[ExactlyWhatItSaysOnTheTin robotic maggot]] that serves as the boss of the [[TechnoWreckage Abandoned Factory]].
* ''VideoGame/JakAndDaxter'': The Precursor robots, with one of them being piloted by Gol and Maia during their FinalBoss battle. You also get to encounter the occasional Dark Maker robot in the third game.
* ''Franchise/MassEffect'': Reapers go a bit beyond this into "Mechanical EldritchAbomination", but they'd have to count the few times you fight one on foot -- most notably Priority: Rannoch, which famously involves syncing up a target pointer to the biggest fleet in the galaxy and having them rain Thanix projectiles on its weak point. It takes one hell of a pounding to down it, and it's the ''smallest'' type of Reaper -- a mere 160 meters tall[[note]]the same height as [[https://commons.wikimedia.org/wiki/Category:160-meter-tall_buildings all of these tower blocks]][[/note]], unlike its two-kilometer long siblings.

* ''Franchise/{{Metroid}}'': Despite its futuristic setting, the series has a bigger focus on large monsters instead of large machines when it comes to bosses and antagonists. However, some cases still exist:

* In ''VideoGame/PuellaMagiMadokaMagicaPortable'', the witch Gisela is a TransformingMecha made of motorcycle parts that can cloak itself in a whirlwind.
* The boss Fernus from ''VideoGame/{{Teslagrad}}'' is a mechanical dragon (it looks a lot like the Truckasaurus, actually) that lairs in the bottom of the Tower. It has the requisite firebreath, and has magnetic powers.
* ''VideoGame/ProfessorLaytonAndTheMiracleMask'': The game has a large robot (only known as "mechamutt", due to its dog-like face) fought in the last regular level of the Toy Robot minigame. Unlike the smaller, weaker dog robots that appear in the other levels, the Mechamutt is large, strong and capable of moving around while covering a wide area, thus being a lot more dangerous. The main character (a small toy robot built by Emmy) has to use a windup key to ram at the monster and damage it (the process has to be done twice to defeat it).
* ''VideoGame/EtrianOdyssey'': Mechanical bosses aren't too frequent in the series, because of the fantasy setting, but they exist:
** ''VideoGame/EtrianOdysseyI'': Though the original game averts the trope, ''The Millenium Girl'' remake adds two robotic bosses in the also-added dungeon Gladsheim: The first is Gimle, which is capable of shooting powerful missiles at the player's party even before its boss battle properly begins; and the second is [[spoiler:M.I.K.E., which by the point it's found goes haywire and must be destroyed]]).
** ''VideoGame/EtrianOdysseyIIITheDrownedCity'': The Gatekeeper is a black robot that serves as the boss of the Molten Caves, and aims to protect the entrance to the Abyssal Shrine at all costs (it was originally build by the Abyssal King to prevent outsiders from going further). Its attack repertoire is also very varied, including laser beams and missiles, and its individual parts can be separated to attack more efficiently.
** ''VideoGame/EtrianOdysseyIVLegendsOfTheTitan'': The Cradle Guardian is the KingMook of the robotic F.O.E. that roam the Echoing Library, and is capable of switching its strengths and weaknesses at will. It's summoned by [[spoiler:Prince Baldur, who in that moment is being corrupted by the influence of Yggdrasil, and is kidnapping the Medium to revive the Yggdrasil]].

* In ''Webcomic/TheInexplicableAdventuresOfBob,'' [[GadgeteerGenius Molly]] [[https://bobadventures.thecomicseries.com/comics/377 builds one,]] seemingly just for fun.

* Franchise/{{Transformers}} has several, including the Terrorcon combiner team, the Monsterbots, the [[MixAndMatchCritters Fuzors]] and Trypticon.

* The old ''WesternAnimation/StarWarsDroids'' cartoon featured one of these in the form of the villainous Great Heep, which eats other droids to refuel and maintains a droid harem. [[Franchise/StarWarsExpandedUniverse Later on he is revealed]] as a member of the Abominor, an entire species of these creatures from outside the main galaxy. They were at war with the Silentium (who are made up of AlienGeometries), which is implied to be the reason for [[Literature/NewJediOrder the Yuzhaan Vong leaving that galaxy]].
* One of the ''WesternAnimation/SupermanTheatricalCartoons'' is actually named "WesternAnimation/TheMechanicalMonsters", featuring a MadScientist with a small army of robots that he built to steal for him. They have twisted, ogre-like forms, grasping claws, a stilted range of motion, and eye-mounted flamethrowers.
* ''WesternAnimation/SamuraiJack'', due to the nature of the setting [[WhatMeasureIsANonHuman and the former rating]], has a lot of those. [[https://www.youtube.com/watch?v=32a7xRs47i0 The fused assassin droids]] in ''Samurai vs Samurai'' really stand out in that regard.

** ''VideoGame/TheLegendOfZeldaBreathOfTheWild'': The Guardians and the Divine Beasts]]. The Guardians are massive SpiderTank machines capable of firing extremely strong lasers, while the Divine Beasts are four HumongousMecha shaped like animals. While the Guardians and the Divine Beasts had been built to protect Hyrule, all of them were literally HijackedByGanon 100 years before the game takes place, and have since been a very high threat for the lives of everybody living in Hyrule.

* In ''WebOriginal/{{Mortasheen}}'', the genocidal villain civilization of Wreathe has nine of these called Celestial Engines, all of them named and themed after planets, as well as the model for all Wreathe's MechaMooks.
