->''"...So they gave me this spear and I said, 'What the hell am I supposed to do with that if we get attacked by giant robots?' and they said, 'First of all, they're called Guymelefs because that sounds more fantasy like...'"''
-->-- '''RedShirt''', ''WebVideo/VisionOfEscaflowneAbridged''

In fiction, HumongousMecha are rarely simply called such. This is particularly true in [[RealRobotGenre Real Robot]]-type shows, where the mecha in question are usually numerous. [[SuperRobotGenre Super Robots]] are typically one-of-a-kind, and such are only called by their [[ICallItVera proper names]]. PoweredArmor may or may not fall victim to this as well.

Keep in mind that, in Japan, the term "mecha" means "anything mechanical," rendering it essentially meaningless -- the word "mecha" specifically means "giant robots" only in the West. Just because a series has a "mecha designer" doesn't mean it has HumongousMecha in it -- the "mecha" designed can even be something like a MagicalGirl's [[Franchise/MagicalGirlLyricalNanoha wand]] (or even [[RobotGirl the Magical Girl herself]], in some settings).

The name used to describe the HumongousMecha tends to be different in just about every series that features them, unless that series is deliberately trying to reference another series.

Similar to NotUsingTheZWord, but the naming is often a matter of trademark law as much as the ScifiGhetto; often, it's also due to RuleOfCool. See also CallARabbitASmeerp.

(By the way, the Japanese generic equivalent to "mech" or "mecha" is ''kitai''.)

'''NOTE''': When adding examples, remember that we're looking for the "generic" name for the mech, not the model designation. In Franchise/{{Gundam}} terms, for example, we're looking for "Mobile Suit" rather than "Zaku", "GM", etc....


[[folder:Anime and Manga]]
* ''Anime/AldnoahZero'' gives us Kataphrakts, named after the heavy cavalrymen of the Byzantine Empire and ancient Persia.
* ''Manga/{{Appleseed}}'': Regular Powered Armor are called Protectors, while the larger MiniMecha are Landmates. And the giant Spider Gun Platforms are referred to as Land Master at least once.
* ''Anime/ArmoredTrooperVotoms'' has Armored Troopers. And VOTOMS actually stands for Vertical One-man Tank for Offense and [=ManueverS=]. Or not.
* ''Anime/AuraBattlerDunbine'' has Aura Battlers which are humanoid-type Aura Machines. It also has the non-humanoid Aura Bombs and Aura Fighters.
* Megadeuses in ''Anime/TheBigO''. Their pilots are called Dominus Megadeus.
* ''Anime/BlueCometSPTLayzner'' refers to piloted models as Super Powered Tracers and unmanned models as Terror Strikers.
* ''Anime/BlueGender'' has Armored Shrike.
* ''Anime/BrainPowerd'' has Grandchilds or Grand Chers (depending on your translation) on the antagonist side, and the titular Brain Powerds on the protagonist side. Universally, a machine with a pilot is called an Antibody (although the term is also used to describe the pilot himself, sometimes).
* ''Manga/BreakBlade'' features {{Golem}}s. Only the titular one is a mech in the traditional sense; modern Golems are more magical / psychic in nature.
* B'ts in ''Anime/BtX'', themed mostly for legendary animals.
* ''Anime/BubblegumCrisis'' calls the PoweredArmor used by the heroines Hardsuits and their transforming motorbike / exoskeletons Motoroids or Motorslaves. Other armors are Battlesuits, and large mechs are called Battlemovers. Genom's ubiquitous synthetic soldiers are known as Boomers. Or, if you prefer mistranslations-made-canon, Voomers.
* ''Anime/BuddyComplex'' uses Valiancers.
* ''Anime/CodeGeass'' has Knightmare Frames (a wordplay between "nightmare" and a "knight's mare"). Later in the series comes the Knight Giga Fortress, which is essentially a giant flying cockpit with KMF technology (equivalent to the Mobile Armor in ''Gundam'').
* ''Anime/CrossAnge'' has Para-Mails, which are based on ancient machines called Ragna-Mails. [[spoiler: The Dragons' Ragna-Mail replicas are called Ryuu-Shin-Ki, or "Dragon Sacred Treasures".]]
* [=KLFs=] and [=LFOs=] in ''Anime/EurekaSeven''. Stands for Kraft Light Fighter and Light-Finding Operation respectively.
* ''Anime/EurekaSevenAo'' refers to its mecha as [=IFOs=], which is short for Intelligent Flying Object. Other [[FlyingCar airborne vehicles]] are referred to as [=FPs=], for Flying Platform
* ''Anime/FangOfTheSunDougram'' has Combat Armor.
* ''Manga/TheFiveStarStories'' call theirs Mortar Headds. (No, that's not misspelled.)
* ''Anime/{{Flag}}'' merely refers to them as Bipdedal Weapons.
* Arm Slaves appear in ''LightNovel/FullMetalPanic'' Arm Slave is for "Armored Mobile Master-Slave System" and is often shortened to just AS. Arm Slaves essentially mimic the [[MotionCaptureMecha movements of their pilots]], so the name actually makes some sense (although you'd think people would come up with a better name for them then that).[[note]]The established term for this in sci-fi is a "{{Literature/waldo}}", or maybe "voodoo control". Whether this is better or worse term is dependent on the beholder.[[/note]] In a author's note in the novel, it's mentioned that when the Americans first revealed the "AS" acronym, the general public thought it was short for "Assault Soldier". So even though Arm Slave is the official term, Assault Soldier is the popular name among civilians mostly because it just sounds better.
* Normal mechs in ''Anime/GadGuard'' are called Heavy Metals while the entities created from the titular Gads are called Gadrians. This is futher divided into the living Super Robots the protagonists use which are Techodes, and the a giant monsters called A-Techodes that are created if a Gad falls into unworthy hands,
* ''Anime/GaikingLegendOfDaikuMaryu'' refers to its mechs as Giants of Flame, since they're powered by an AppliedPhlebotinum called "Flame".
* ''Anime/GaoGaiGar'' is a [[CombiningMecha Super Mechanoid]]; its components are a Mechanoid and a set of Gao-Machine vehicles. The related ''Anime/{{Betterman}}'' mecha are called Neuronoids because their power relays and controls are affected by their pilot's nervous systems. The sequel novel ''[=GaoGaiGar=] vs Betterman'' (formerly known as ''Project Z'') features [=GaoGaiGo=], a hybrid design referred to as a Neuro-Mechanoid.
* ''Anime/{{Gasaraki}}'': One side calls their mechs Tactical Armor, ([=TAs=]). The other -- (Metal) FAKES. Both were based on the giant demonic creatures dressed in samurai armor known as Kugai (the group that calls their mechs FAKES refer to the Kugai as Originals.)
* In the ''Manga/GetterRobo'' metaseries, the airplane components are known as Getter Machines, while the actual combined unit is known as a Getter Robo. Robots that aren't powered by [[AppliedPhlebotinum getter rays]] are simply called Super Robots.
* ''Anime/GiganticFormula'' has Gigantic Figures.
* ''Anime/GingaHyouryuuVifam'' call them Round Vernians. While Earthling use the term to classified all mech, the alien actually call them as "machine".
* ''Anime/GingaKikoutaiMajesticPrince'' uses AHSMB devices which means: Advanced High Standard Multipurpose Battle.
* ''Anime/{{Gravion}}'' brings us the Gran Divas, the name for the individual parts that make up Gravion, the Gran Kaiser, its central core, and the Gran Troopers, the [[RealRobotGenre Real Robot]] variants that show up in Gravion Zwei.
* ''Anime/{{GunBuster}}'' has the [[RealRobotGenre RealRobot]] Machine Weapons, and the [[SuperRobotGenre Super Robot]] Buster Machines.
* ''Franchise/{{Gundam}}'' started all this when they called theirs Mobile Suits (humanoid mecha) and Mobile Armor (jet-like, tank-like, and other non-humanoid mecha).[[note]]The specific difference is that Mobile Suits take advantage of limb momentum to change their position in a weightless environment, while Mobile Armors do so largely through thrusters[[/note]] A "normal suit", if you're wondering, is a regular spacesuit. (And a "pilot suit" is the LatexSpaceSuit version, easier to move in and fit into cramped cockpits.).
** ''[[Anime/MobileFighterGGundam G Gundam]]'' adds Mobile Fighters, which mostly differ in their MotionCaptureMecha controls (and the fact that they're [[SuperRobotGenre Super Robot]]s). Regular Mobile Suits still exist, but they're far less present in the series. They're actually more ''numerous'' than the Mobile Fighters (being mass produced for military and police duty), it's just that Mobile Suits are incidental to the story, and absolutely no match for a Mobile Fighter.
** ''[[Anime/MobileSuitGundamWing Gundam Wing]]'' adds the automatic Mobile Dolls...
** ...and ''[[Anime/AfterWarGundamX Gundam X]]'' gives us Mobile Bits, which are like Mobile Dolls except controlled [[PsychicPowers telepathically]] instead of by computer.
** Novel ''Literature/GaiaGear' add Man Machine, which look like mobile suit, but with advance technology that's on completely another level.
* ''Anime/GunXSword'' calls theirs Yoroi, Japanese for "armor".
* ''[[Anime/HeavyMetalLGaim Heavy Metal L-Gaim]]'' also call them Heavy Metal.
* ''Anime/InnocentVenus'' has Gladiators.
* ''Anime/KiddyGrade'' has Guard Robots (which double as vehicles), and the (non-pilotable) Genetech Beasts which range from dog-sized to [[HumongousMecha humongous]]. The ''Anime/KiddyGirlAnd Pure'' manga also has a variety of unnamed piloted mecha and a humanoid Humanic Frame.
* ''Anime/M3TheDarkMetal'' has MA-Vess
* The titular Machine Robos of the ''Toys/MachineRobo'' franchise.
* ''Anime/{{Macross}}'': Variable Fighters (TransformingMecha, with the mecha mode additionally being refered to as a Battroid) and Destroids (Non-Transforming). The Zentraedi also have their Battle Pods. Also, variable fighters are frequently referred to as Valkyries, which was the actual nickname of the first regular production VF.
* ''Manga/MagicKnightRayearth'' In Cephiro, a Rune-God is basically a mecha that's controlled by a Magic Knight's spirit. This is an attempted {{Woolseyism}}--the original Japanese PunnyName is "Mashin", both "Demon-God" and "Machine". In the [[UsefulNotes/LatinAmerica LatAm]] dub made in LA they're known as "Genies", in the OVA's dubbed in mexico they are just "Gods".
* ''Anime/MarsDaybreak'' has Round Bucklers. They are further separated into Corded and Cordless, the difference being that the former are remotely controlled through EVA-style umbilical cables linked to a "Seahorse" command craft and the later have a conventional cockpit.
* ''Anime/{{Megazone 23}}'' has transformable Maneuver Slave.
* Metal Armor from ''Anime/MetalArmorDragonar''.
* ''Anime/OvermanKingGainer'' has two different type of mechas, the mass produced Silhouette Machine which are a type of RealRobot, and the Overman which are rarer (usually only one type) and can use the Overskill.
* In ''Anime/PanzerWorldGalient'', each mech line is classified with the prefix word Panzer. For example, Galient is Panzer Blade, centaur mechs like Promaxis are Panzer Trampler, while flyable Wingals are Panzer Gust. Collectively, they're called Armored Soldiers (Kikouhei).
* ''Anime/{{Patlabor}}'' calls them Labors since they're mostly used for industrial work. The series name refers specifically to police Labors, being a shorthand for ''Patrol Labor''.
* ''Manga/{{Pluto}}'' by Urasawa Tezuka has Brando using a Combat Suit in a war and a Pankration for championship fighting.
* ''Anime/{{RahXephon}}'' has Dolems, smaller craft called Dotems and the titular [=RahXephon=], often shortened to "Xephon." The humans also field giant Vermillion robots near the end of the series. However, the Dolems and Dotems are not actually mecha, as they are actually made of clay [[spoiler:(and one of ice)]], feature no actual mechanisms and are shown to be completely solid when broken open. The Rah-Xephon itself is made of similar material and seems to operate in much the same way, bar the remote control, so while it shares a lot of mecha characteristics, it is not a mecha as such, though it still qualifies, as it features what amounts to a cockpit.
* ''Anime/RegaliaTheThreeSacredStars'': There's the Regalia, which are young([[Really700YearsOld -looking]]) girls that transform into giant robots and Regalia Gear, which are normal super robots that the pilots fuse with.
* ''Anime/RinneNoLagrange'' has Ovids (standard-issue mechas) and the Vox (superpowered ones used by the protagonists). For the lead protagonist and up to the last moment a clueless more-or-less ordinary schoolgirl Madoka, the terminology is hardly relevant, she usually refers to them as robots, quickly settling to refer to her personal Vox as "Midori", a color-pallette-based nickname.
* ''Anime/{{Robotech}}'' mostly uses the same names as ''Anime/SuperDimensionFortressMacross'', although the fighters and other human transforming mecha are called Veritechs. Although the series often ''did'' refer to them collectively as "Mecha." The VF-1 Veritech was [[RetCon retroactively renamed]] the "VF-1 Valkyrie Veritech Fighter" after the Macross original in time for the 20th anniversary release of ''WesternAnimation/RobotechTheShadowChronicles'' in 2006.
* ''Anime/ShiroganeNoIshiArgevollen'' has Trail Kriegers.
* ''Sinna 1905'' (an early manga by Creator/MohiroKitoh) has Tomikrots.
* ''Anime/SkyGirls'' has the Sonic Divers.
* ''Anime/TheGirlWhoLeaptThroughSpace'' has QT ARMS (or Quantum Technology Advanced Reinforced Maneuvering Shroud) for the main girls, with the B.O.A.R Ship (Beyond Orbit Azonal Runabout) for two employees of the Space Police, and a mechanised force called Existence [[spoiler: who were made to serve the titular Girl Who Leapt Through Space]]
* In ''Anime/SpaceRunawayIdeon'', the Buff Clan actually use the term Heavy Mecha.
* ''Anime/StarDriver'' gives us Cybodies.
* ''Anime/StrainStrategicArmoredInfantry'' has [=STRAINs=] ([=STRategic Armored INfantry=]) and [=GAMBEEs=] (General Axis Motorized Battle Exoskeleton Equipment).
* The Galactic Alliance in ''Anime/GargantiaOnTheVerdurousPlanet'' uses Machine Caliburs. On Earth, they call similar machines Yunboroids.
* In ''Anime/SuperDimensionCenturyOrguss'':
** In the original, the Chiram faction call mecha Devices.
** The sequel ''Orguss 02'' simply called them Armor in the original Japanese, while the dub called them [[{{Woolseyism}} Decimators]].
* ''Anime/TengenToppaGurrenLagann'' has the [[SuperRobot Gunmen]], while the mass-production Gurren Lagann replicas are called [[SpellMyNameWithAnS Grappal/Gurapural/Grapearl]]. However, the word "mecha" ''is'' actually used in-show at least once.
* ''Anime/{{Utawarerumono}}'' has the (Eva-like) Avu Kamuu or [[SpellMyNameWithAnS whatever it's spelled]].
* ''Anime/{{Vandread}}'' has the mecha used by the men called Bangata ("Barbarian" - although the translations call them "Van-type" instead) which the women call Vanguards; while the spacefighters that the women use are Dreads. [[TitleDrop When the two combine]]...
* ''Anime/TheVisionOfEscaflowne'': Guymelefs. Smaller ones were simply known as Melefs but these never played much of a role in the series.
* ''Anime/{{Xabungle}}'' has Walker Machines. The titular WM gets the Combat Mecha due to the fact that dedicated combat [=WMs=] are rare.
* ''Manga/YuukyuuMokushirokuEidronShadow'' calls them Shadows.
* ''Franchise/{{Zoids}}'' has, well, Zoids.
** Its SpinOff ''Soukou Kyoshin Z-Knight'' start with Armored Titans, six SuperPrototype powered by zoid core, Battle Armor which is smaller and entirely built by Earthlings, and Metal Foot which is even smaller and unmanned.

[[folder:Comic Books]]
* ''Spitfire and the Troubleshooters'', from Marvel's original ComicBook/TheNewUniverse series, revolved around the team's escapades with the M.A.X. (Man-Assisted eXperimental) Armor.
** Warren Ellis' rebooted ''newuniversal'' series reimagined this with the H.E.X. (Human Enhancement eXperimental) Initiative, a project to create a robotic battle suit and hunt metahumans.
* For DC Comics, there's the Rocket Red Armor, Soviet-based PoweredArmor built by Franchise/GreenLantern Kilowog.
* Doesn't matter how tall they are or if they're piloted or not, those mutant-hunting robots that give the ComicBook/XMen hell are all known as Sentinels.

[[folder:Fan Works]]
* ''Fanfic/ACrownOfStars'': The Star Striders and Black Knights warmech units of the Avalon Army. A Star Strider is a TransformingMecha looks like a ''[[Anime/PanzerWorldGalient armored soldier]]''/''[[Anime/MobileSuitGundam mobile suit]]''/''[[Anime/{{Patlabor}} labor]]'' hybrid... or like if a ''[[Anime/MazingerZ mazinger]]'' and a [[Anime/SuperDimensionFortressMacross valkyrie]] got a child, and their offspring fused with a ''[[Franchise/TheTransformers autobot]]'' and grew ''Anime/GunBuster'''s double cockpit.
* ''Fanfic/TheChildOfLove'': The Evangelions. At the end of the story Shinji and Asuka learn what those half-organic giant robots hide inside due to [[spoiler:Gendo's actions.]]
* ''Fanfic/DoingItRightThisTime'': The cybernetic giant robots Evangelions, as well known as "the secret anti-kaiju weapon that will work."
* ''Fanfic/{{HERZ}}'': The Evangelions, bio-mechanical giant robots. Many nations try to produce their own Evas, and one of the missions of HERZ is preventing this from happening.
* ''Fanfic/LastChildOfKrypton'': The Evangelions, humongous half-biological robots. Dr. Akagi calls them “artificial human”. Touji’s sister calls them "big robots".
* Being a crossover fic, ''Fanfic/ThousandShinji'' gives us two examples: the Evas of the ''Evangelion'' universe, and the Titans of the ''Warhammer 40000'' franchise.

* ''Franchise/StarWars'' usually calls them Walkers or [=ATs=] (All Terrain).
* ''Film/TheMatrix'' series has [=APUs=], standing for Armored Personnel Units. Though looking at them, 'armored' is somewhat less than accurate.
** ''Anime/TheAnimatrix'' did show the early [=APUs=] having armor during The Human-Machine War. [[ArmorIsUseless 01's Combat Harvesters cut them open like tin cans with their lasers and ripped apart the pilots inside.]] The Zion [=APUs=] most likely never had them in the first place or were removed later to save space and collect resources.
* In ''Film/{{Avatar}}'' they are known as Amplified Mobility Platforms, or simply AMP suits.
* ''Film/PacificRim'' calls its mechs Jaegers which is German for [[MeaningfulName "Hunter"]].

* Going a [[OlderThanRadio fair ways back]], Creator/HGWells simply called his Fighting Machines. They're also frequently refered to as Tripods, although the original book rarely used the name.
* There was also the novel named ''Warstrider'' that called its, guess what...
* Creator/DaleBrown's ''Act of War'' duology has CID or Cybernetic Infantry Device. Other books have a [[PoweredArmor skinsuit]] colloquially called Tin Man, or officially BERP (Ballistic Electro-Reactive Process), because its inventor has a juvenile sense of humor.
* Mechs in ''Literature/TheHistoryOfTheGalaxy'' series by Andrey Livadny are officially called serv-machines. Alternatively, they are often referred to as "walking machines".
** Oftentimes, they are simply referred to by their class, with the two most famous ones being the "Phalanxer" (heavy, long-range mech) and the "Hoplite" (lighter, scout mech). Others are sometimes mentioned, such as the "Raven" (between a "Phalanxer" and a "Hoplite") and the "Golden Eagle" (a discontinued model).
* The mecha used by the Japan Self-Defense Force in ''Literature/StoneKing'' are known as titans.
* Mechs in ''{{Literature/The Osmerian Conflict}}'' are simply known as mechina.
* Silhouette Knights, the {{Magitek}} mecha from ''LightNovel/KnightsAndMagic'' are distinctly not robots, but massive, magically powered suits of armor.

[[folder:Live Action TV]]
* ''Franchise/PowerRangers'' has Zords, named for the sage Zordon from the early seasons (though seasons with no connection to Zordon and company also call their HumongousMecha "zords," and the [[CombiningMecha combined forms]] "Megazords"). Since Bruce Kalish came along, villain-used mecha are just called 'giant robots'. More specifically, "Zord" was originally a shortening of "Dinozord", a play both on the sage who had created them and the ancient animals on which he had modeled several of his designs.
** The ''Franchise/SuperSentai'' source material doesn't have a standardized name for all the mecha (and some seasons even neglect to add that name), but in some amusing {{Mythology Gag}}s, ''Series/MiraiSentaiTimeranger'' featured a villain mecha called the G-Zord, and ''Series/TokumeiSentaiGoBusters'' classifies ''all'' of their villainous giant robots as "[=MegaZords=]" (with that capitalization).
*** Come the climactic battle in the [=Go-Buster/Gokaiger=] crossover movie, both teams are given the ability to use [=MegaZord=] Keys to transform their mecha, using the term for several previous series' robos, as well
** However, The ''Super Sentai Battle Dice-O'' card game classifies all forms as Mecha, while the individual forms are called Machines and the combined forms are called Robos.
** Not for ALL the mecha, but each season tends to use a different one. Vehicular mecha are sometimes called 'Machines', bestial ones are 'Animals' or '-Ju' (meaning animals), and combined mecha are sometimes called 'Robo' (usully tech-themed seasons) 'King', or the Japanese '-Oh' (meaning 'king') or 'Jin' ('god', both in the mystically-aligned seasons). There's lots of single-season terms sometimes lampshaded in the season title, like 'Kidenjuu' (''Series/GoseiSentaiDairanger''), 'Bakuryu' (''Series/BakuryuuSentaiAbaranger'') 'Majin' (''Series/MahouSentaiMagiranger''), and 'Origami' (''Series/SamuraiSentaiShinkenger''). Sometimes it gets rather inconsistent ('Vehicles' referred to the regular vehicles in ''Dekaranger'' and the ''mecha'' of ''Boukenger''.)
** In an aversion of the usual naming system, the celestially-derived mecha of ''Series/TensouSentaiGoseiger'' are called Gosei''Machines''.
** The individual mecha from ''Series/ShurikenSentaiNinninger'' are called "[=OtomoNin=]", whcih roughly translates into "ninja buddies".

[[folder:Tabletop Games]]
* ''TabletopGame/BattleTech'':
** Often actually ''does'' call them 'Mechs, short for a variety of giant robot applications, but ''usually'' meaning Battlemechs or Omnimechs. Civilian 'Mechs for agriculture, Agromechs, and industrial 'Mechs, with no canonical name given, are also known to exist. They actually hold the trademark for the term "mech", which is why one runs into "mecha" frequently. The ''very'' first edition was called ''TabletopGame/BattleDroids'', but someone ''[[Franchise/StarWars else]]'' held the trademark for ''that'' term.
** [=IndustrialMechs=] exist as well. It's just that they are so varied that there really is no one "category" of [=IndustrialMechs=]. You have [=LoggerMechs=], [=LifterMechs=], the long list even includes [=CattleMechs=]. There are even [=Securitymechs=] and [=MilitiaMechs=], Industrialmechs built with military grade armor and weaponry as a cheaper alternative to the more advanced Battlemech in defensive roles. [=Industrialmechs=] have been a part of the setting since the beginning, but only received official rules for use and construction relatively recently, with earlier appearances being background lore or novel based only. Many of these early appearances have since had official stats created for them, and the Mechwarrior Dark Age spinoff added a number of new designs in its early waves of figures, most of which have since received official stats in the core battletech game as well.
** In addition to various sorts of Mechs, both sides also use [[PoweredArmor Battle Armor]], and the Clans field MiniMecha called Protomechs.
* The title of ''TabletopGame/{{Mekton}}'' is also the default name for mecha in it, though plenty of others exist on a 'verse by 'verse basis.
* ''TabletopGame/{{Warhammer 40000}}'':
** The Imperium has ''tons'', enough to spawn the ''Titan Legions'' GaidenGame. While it has some elements of [[RealRobotGenre "realism"]] with how it's handled, like the rest of 40k, it runs on RuleOfCool.
*** That said, the Imperium has two broad classes that their mechs fall under. The first is Knights, who come from the noble families of feudalistic worlds and have ties to the [[MachineWorship Adeptus Mechanicus]]. They serve as a minority part of the Imperium's military force, though there are Knights Errant roaming the galaxy, looking for other humans to help. Most Knight chassis are a humpbacked mech about 7 meters tall, though there are some rarer chassis that are up to a few meters taller. They typically have a gun, sometimes a melee weapon, on each arm, and a relatively tiny medium machine gun for support fire; and are crewed by one, maybe two pilots. Political associations aside, the main difference between Knights and Titans is that Titans are (broadly speaking) larger and have access to more, bigger, and deadlier guns.
*** Then comes the Titans of the Adeptus Mechanicus, which is fully a splinter faction of the Adeptus Mechanicus. Unlike the Knights, these things are considered actual God Machines, and they get more guns the higher up you get on the scale. Their chassis ranges in size from the 15-meter-tall Warhound Scout Titan to the gargantuan Imperator-class Titan, a 55-meter walking cathedral-fortress able to house a company of soldiers and sporting weapons rated against capital ships. And sometimes they get a few offshoots in the process, either from a lost blueprint or after one too many retrofits. The canon is ''massively'' inconsistent on actual scale; Imperators especially can be anywhere from 40 to 100 meters tall depending on source.
*** The Imperium also has Dreadnoughts. MiniMecha about four to about four-and-a-half meters tall, piloted by a [[EmergencyTransformation mortally-wounded]] SpaceMarine's life-support sarcophagus. The standard is the boxy Castraferrum chassis, which looks like an ornate metal crate with arms and legs. Then there's the taller and more humanoid Contemptor Dreadnought, which has the benefit of loosely resembling the Space Marine inside. There was also the five meter Leviathan Dreadnought, which was a heavily armoured beast designed for sieges and heavy assaults and originates from the Horus Heresy; but the exotic technologies involved and limited numbers built means that the secrets of its construction disappeared into history. There are few Space Marine Chapters that have any Contemptor Dreadnoughts, and even fewer that have Leviathans, and either one is rarely used if they're present.
*** The Imperium will use these designations when referring to other races' war machines, such as [[HordeOfAlienLocusts Tyranid]] [[OrganicTechnology Bio-Titans]] or [[SpaceElves Eldar]] "Dreadnoughts" (which the Eldar call Wraithlords, and are actually piloted by the [[SoulJar Spirit Stone]] of a departed warrior. The Eldar don't seem to have a different name for their own Titans, though).
** Orks call their Titan-sized walking junkheaps Gargants, refer to roughly Knight-sized walkers as Stompas, and have Deff Dreads or Killa Kans for their Dreadnought analogues. That said, Ork design is so non-standardized that there's a bit of overlap between these categories.
** The Tau consider Titans to be AwesomeYetImpractical, and favor using MiniMecha-sized Battlesuits that at 2.8 meters tall are a bit smaller than an Imperial Dreadnought. However, they're recently begun fielding the twice as large [=XV104=] "Riptide" Battlesuit that comes closer to an Imperial Knight.
* ''TabletopGame/{{Exalted}}'' calls their mecha Warstriders.
** Variants include the Colossus (actually Alchemical Exalts who, at an age of over 100, have grown to mecha-scale) and the Hellstrider (which is a warstrider made from living demons).
* ''TabletopGame/JovianChronicles'' has Exo-Armors (battlesuits are referred to as Exo-Suits), and TabletopGame/HeavyGear and TabletopGame/GearKrieg has Gears in Dream Pod Nine's series of mecha TabletopGames. HG's bigger mecha are called Striders.
* Engels from ''TabletopGame/CthulhuTech'', which have [[OrganicTechnology more in common]] with Evangelions than they do anything else on this list.
* ''TabletopGame/BlissStage'' has the [=ANIMa=], or '''A'''lien '''N'''umina '''I'''nversion '''Ma'''chine. It's not [[EmpathicWeapon literally a giant robot,]] though.
* ''[[TabletopGame/IronKingdoms Warmachine]]'' gets its name from its big, steam powered robots called Warjacks. The predecessors to modern warjacks were the much-larger Colossals, which were obsolete for a while but have started being produced again by all the major nations of Immoren.
* ''TabletopGame/{{Rifts}}'' typically uses the term Robots to refer to piloted humanoid combat machines, though the lines between them and PoweredArmor are frequently blurred. The training skills are referred to as "robot combat" and the most prominent series of designs is the IAR; Infantry Assault Robot.
* ''TabletopGame/{{GiantGuardianGeneration}}'' has the General Enforcement Anthropomorphic Robot, or [[FunWithAcronyms Gear]].
* The [=CAMELOT Trigger=] setting for the ''TabletopGame/FateCoreSystem'' (contained in the second "Fate Worlds" supplement) simply calls them Armour. Complete with British spelling to match [[Myth/KingArthur its obvious inspiration]].
* Outrider Studios' ''Remnants'' refers to its LostTechnology robots as Ishin. This is because in-universe everything left over from the apocalyptic war that destroyed the society is referred to as a Remnant, or "Ishi", and the giant robots are the leftovers that are most likely to be functional due to really neat self-repair systems.
* The MiniMecha of ''TabletopGame/{{Infinity}}'' are referred to as Tactical Armoured Gear, or simply [=TAGs=].
* ''TabletopGame/MobileFrameZero'' features MiniMecha called Mobile Frames, which players individually [[BuiltWithLEGO build by hand from LEGO pieces]].
* The relatively unknown ''CAV'' tabletop game by Reaper Miniatures features its eponymous "Close Assault Vehicles." The game's visual inspiration owes a lot to ''TabletopGame/BattleTech'' and ''[[VideoGame/{{Starsiege}} Earthsiege]]''.

[[folder:Video Games]]
* ''VideoGame/ArmoredCore'' has... well, Armored Cores. They're subdivided further into MT ("Muscle Tracer") which are precursors to Armored Cores, Normals, which are the average Armored Core until ''Armored Core 4'', and [=Nexts=] which use the series' newest {{Phlebotinum}} Kojima Particles to make them vastly more powerful.
* The mechas in ''VideoGame/ArmoredWarriors'' are called Variant Armors (also [[SpellMyNameWithAnS misromanized]] "Valiant Armors").
* The SNES game ''VideoGame/BattleClash'' called their robot vehicles Standing Tanks (or S.T.'s for short). This is because the "Battle Game" was originally fought with outdated tanks until it got popular enough for the participants to build machines from the ground up. Even when the machines start flying, the term "standing tank" sticks.
* ''VideoGame/Battlefield2142'' has Battlewalkers, or just Walkers for short.
* HOUNDS of ''VideoGame/ChromeHounds''. The name doesn't actually stand for anything, it's a reference to the way squads of them act like a pack of hounds. HOUNDS are actually evolutions of Advanced Combat Vehicles or [=ACVs=], which act as the game's {{Mecha Mooks}}.
* ''VideoGame/CityOfHeroes'' have the Malta's Titans (Hercules, Zeus and Cronos class) Vanguard has their HVAS (Heavy Vanguard Assault Suit) and the Longbow have their Cataphract (it's equivalent, the Arachnos Heavy Blaster, is a SpiderTank instead)
* ''VideoGame/CustomRobo'' has Custom Robo.
* ''VideoGame/{{Cyberbots}}'' makes use of Variant Armors'' for mooks, borrowing them from ''VideoGame/ArmoredWarriors''.
* ''VideoGame/{{Demonbane}}'' has two types. A mundane Destroyer Robot and {{Magitek}}-based Deus Machina.
* ''VideoGame/DestroyAllHumans'': Pox's Big Willy.
* ''{{VideoGame/Exteel}}'' has Mechanaughts.
* ''VideoGame/FinalFantasyVI'' has [[MagiTek Magitek Armor]] as the most recognizable, but others exist as well.
* The ''VideoGame/FrontMission'' series has Wanzer's, which is a portmanteau of ''Wanderung Panzer'' (German for "Walking Tank").
* ''G-Nome'' has the Heavily Armored Weapons Chassis, or HAWC.
* Terran Empire from ''[[VideoGame/GroundControl GroundControl II: Operation Exodus]]'' has Combat Striders and Missile Striders.
* The ''VideoGame/{{Gungriffon}}'' series has the AWGS which stands for Armored Walking Gun System.
* In ''VideoGame/GunparadeMarch'', they're called Humanoid Walking Tanks, or [=HWTs.=]
* ''VideoGame/HalfLife2'' and the ''Episodes'' have classic HG Wells tripods known as Striders. Nearly all [[TheEmpire Combine forces]] are species that have been previously enslaved, surgically implanted with weapon systems, and forcibly evolved around them. These various types of semi-organic enemies are collectively referred to as "synth." As such, Dog rips the brain out of a Strider in ''Episode 2''.
* Dolls in ''Heavy Nova''.
* ''VideoGame/HeroesOfMightAndMagic IV'' has Dragon Golems as one of the two top tier units of the [[TheMagocracy Order faction]]. A huge mechanical dragon piloted by dwarves may be called a Golem, but it is a HumongousMecha.
* ''VideoGame/IronBrigade'', true to its WWI roots (and its former title, ''Trenched'') has Mobile Trenches.
* ''VideoGame/{{Ironcast}}'' has the eponymous Ironcasts, {{Steampunk}}-style mechs ranging from the normal 20 ft. models to the humongous Gargantuan-class.
* The UsefulNotes/AtariJaguar game ''Iron Soldier'' is named after the Iron Fist Corporation's Iron Soldiers (abbreviated IS), 42-foot tall humanoid robots with a single pilot and a modular weapons system. The player is a member of LaResistance who has stolen a prototype IS and is out to fight through the IFC's armies of tanks, helicopters, and Soldiers.
* In ''VideoGame/JakIIRenegade'', we have the Titan Suit.
* ''VideoGame/LostPlanet'':
** ''Lost Planet: Extreme Condition]]'' has the Vital Suit, or [=VS=]. Models range from simple open-cockpit machines to advanced [[SpiderTank quadrupedal]] models that [[TransformingMecha can turn into tanks]] and ones with arms (with hands and [[BladeBelowTheShoulder mounted]] [[ChainsawGood chainsaws]]) and hover jets.
** ''Lost Planet 2'' adds multi-seaters, tamed Akrid, and even [[CombiningMecha one that can combine with another]].
** ''Lost Planet 3'', being a prequel, uses Rigs, which are much cruder and meant for exploration and mining.
* ''VideoGame/MadStalkerFullMetalForce'' has Slave Gears.
* ''Franchise/MassEffect'':
** The security robots in ''VideoGame/MassEffect2'' are simply referred to as mechs (although only some of them are humongous). The geth in both games use humanoid troopers, four-legged Armature support, scaled-up-humanoid Destroyer units for melee combat, and lizard-like Stalkers for ECM support.
** Averted in ''VideoGame/MassEffect3'', by the [[NGOSuperpower Cerberus commissioned]] Atlas Mechs, who's name is borrowed from ''TabletopGame/BattleTech''. They can lift a person up in the air and crush them, and [[PlayerCharacter Commander Shepard]] can hijack them.
* ''Videogame/MechWarrior'', set in the ''Tabletopgame/BattleTech'' universe, likewise has the signature 10 meter tall [=BattleMechs=], commonly known just as 'Mechs. A few games also feature [=OmniMechs=], which use modular weapon pods for the DesignItYourselfEquipment. The games also typically feature man-sized "Battle Armor" PoweredArmor, but only ''[=MechWarrior=]: Living Legends'' and the modded re-release of ''[=MechWarrior 4=]: Mercenaries'' allows players to use them
* ''VideoGame/MegaManX'' has the Ride Armors, which are largely forgotten later on in the videogame series. To a lesser extent are the Mechaniloids, self-controlled robots that are nevertheless not humanoid like a Reploid, and which are often created for specific tasks and aren't programmed to be able to make their own decisions as a result.
* ''Metal Brigade Tactics'' calls them Vertical Armor.
* ''VideoGame/MetalFatigue'' has Combots.
* ''VideoGame/MetalGear'': Early Kojima nomenclature (''VideoGame/{{Metal Gear|1}}'', ''VideoGame/MetalGear2SolidSnake'' and ''VisualNovel/{{Snatcher}}'') made Metal Gears a subgroup of mechs as a whole, which were referred to as Heavy Walkers. The presence of Metal Gear Gustavs, a rejected boss from ''Metal Gear 2'', suggested that the term "Metal Gear" was just an affectionate nickname for Heavy Walkers. ''VideoGame/MetalGearSolid4GunsOfThePatriots'' [[RetCon clarified]] the issue by saying that the difference between a Metal Gear and a Walking Tank is that the Metal Gears are useful in terms of the global nuclear map, and Walking Tanks (like the Gekkos) are simply weapons. This was probably brought into the canon because the main Metal Gear of ''VideoGame/MetalGearSolid2SonsOfLiberty'' was more of a [[spoiler:submarine.]] Regardless, by ''VideoGame/MetalGearRisingRevengeance'' the term "Metal Gear" has essentially taken over for concepts similar to real [=UAVs=] and [=UGVs=], as AI-controlled weapons similar to the Gekko are now referred to as "Unmanned Metal Gears", or more simply "Unmanned Gears".
* ''Metal Warriors'' for the SNES has Battledroids.
* The ''VideoGame/OneMustFall'' series of robot fighting games called 'em H.A.Rs (Humanoid Assisted Robots), though most characters in-game still referred to them as just robots or "'bots."
* ''VideoGame/PhantomCrash'' and its sequel ''VideoGame/SLAISteelLancerArenaInternational'' feature a variety of [=SCUBIs=] or Scoot-Vehicles, commonly referred to as "Scoobees" or "[=SVs=]".
* ''VideoGame/{{PlanetSide}}'' has the [=BFRs=], fully known as Big F-- err, I mean, Battle Frame Robotics, and nicknamed Biffers by players. The Mechanized Armored Exo-Suit {{PoweredArmor}} is abbreviated as MAX.
* ''VisualNovel/{{Policenauts}}'', another Kojima game, referred to its mechas as Extravehicular Mobility Police Suits or EMPS, which are named as such because they're piloted by members of the Advanced Police unit of the Beyond Coast Police.
* Power Loaders in ''VideoGame/PowerDolls'', because these vehicles were built upon heavy loader's chassis.
* ''VideoGame/RingOfRed'' called them [=AFWs=] (Armored Fighting Walkers).
* ''VideoGame/RobotAlchemicDrive'' gives us Meganites for the human controlled robots. The enemy aliens are all called Volgara, but this is more a species name than a type of mech.
* ''Videogame/SakuraWars'': The Tokyo and Paris Flower Divisions call theirs Koubu (or Kohbu, whichever spelling you prefer), the now-defunct European Star Division has Eisenkleids, and the New York Star Division (at least in the English translation of [[VideoGame/SakuraWarsSoLongMyLove the fifth game]]) calls them S.T.A.R.s. Those are model names; the generic term is Ryoushi Katchuu (bless you), which translates as "psychic particle armor".
* ''VideoGame/SenkoNoRonde'' has Rounder.
* Creator/BioWare game ''VideoGame/ShatteredSteel'' has Planet Runners.
* ''VideoGame/ShogoMobileArmorDivision'' has [=MCA=], Mobile Combat Armours.
* ''VideoGame/StarCraft'': Sometimes.
** In ''VideoGame/StarCraftI'' and the single-player campaign of ''VideoGame/StarCraftIIWingsOfLiberty'', the manual [[AvertedTrope uses "mech"]] for the Goliath.
** ''VideoGame/StarCraftII'' calls the [[TransformingMecha Viking's]] ground mode an "assault walker". The [[HumongousMecha Thor]] and its story-only SuperPrototype the [[HumongousMecha Odin]] don't actually get a description like this, but are best described as self-propelled artillery pieces.
** In its introductory mission in the campaign, the Odin is described as a "superheavy siege walker" (the less-humongous Thors are "heavy assault mechs"). In general, such units are referred to as "walkers" because "mech" is a [[FanNickname metagame term]] for "mechanical" as a general class, and therefore includes tanks and other vehicles too.
* The ''Videogame/StarSiege'' / ''[=EarthSiege=]'' series has [=HERCULANs=] (Humaniform-Emulation Roboticized Combat Unit with Leg-Articulated Navigation), though they're generally referred to as [=HERCs=]
* ''Bumpy Trot'' a.k.a. ''VideoGame/SteambotChronicles'' has Trotmobiles.
* ''VideoGame/SteelBattalion'' has the Vertical Tanks ([=VT=]). This includes ''Heavy Armor'', which otherwise has a [[ContinuityReboot very different setting]], down to computer-less [=VTs=] that actually look more like {{Walking Tank}}s.
* The ''VisualNovel/{{Sunrider}}'' series has Ryders.
* ''VideoGame/SuperRobotWars'':
** The original game brings Mobile Suits, Variable Fighters, ''and'' Arm Slaves together in the same universe and gives you Personal Troopers (derived from the Gespenst series, which may or may not have started as PoweredArmor) and Armored Modules (derived from jet fighters, with the early models being essentially planes with arms). They also have Dynamic General Guardians, Elemental Lords, Supermechanical Gods, War Machine Dolls, Assault Dragoons, Assault Scouters, Valkyries, Multi Walker and more. The names are assigned to mechs by their ''manufacturers'' (Personal Troopers were developed by Mao Industries, the Lion series are manufactured by Isurugi Heavy Industries , etc.)
** SRW has invented the terms [[SuperRobotGenre Super Robot]] and [[RealRobotGenre Real Robot]] to provide a more general term for the units, and when an all-encompassing name is needed, they just go ahead and call them mechs.
** The ''[[VideoGame/SuperRobotWarsGaiden Masoukishin]]'' subseries is a more straight example, with inhabitants of La Gias using {{Magitek}} mecha called Masouki ("magically-clothed machines", usually translated as Elementals), and referring to any outside mecha they see by that name. There also exist four [[SuperRobot Masoukishin]] ("magically-clothed machine gods", translated as Elemental Lords) and the Chou Masouki (Super Masouki) Duraxyll.
** And in ''VideoGame/EndlessFrontier'', denizen of Kagura Amahara use term Karakuri to call all mechs.
** ''VideoGame/SuperRobotWarsX'': Autowarlocks, which are {{Magitek}}-based robots with magic amplifying abilities used by the Keepers of Order, the guardians of law and order in Al Worth. The original protagonist unit, Zelguard, is one of them.
* Anise Tatlin of ''VideoGame/TalesOfTheAbyss'' carries a small doll ("Tokunaga") on her back which transforms to mecha-sized proportions when deployed and is controlled by Anise for fighting. Interestingly, there's a wide variety of dolls to be found and equipped for different effect, but Anise will ride Tokunaga even when stripped of all equipment. This is because she cannot otherwise fight (even though she can be equipped with a melee weapon).
* ''VideoGame/TitanFall'' has the eponymous Titans, which have limited AI to act autonomously or can be boarded and controlled by their Pilot.
* ''VideoGame/TotalAnnihilation''
** In original game, the infantry units (which are essentially mechs) are called [=KBOT=]s, which [[FunWithAcronyms stands for]] Kinetic Bio Organic Technology.
** Its spiritual sequel, ''VideoGame/SupremeCommander'', features numerous variations of mechs, all called Bots. Except for the one who actually have human pilots. Those are called ACU and sACU. It stands for (support) Armored Command Unit.
* ''VideoGame/VanguardBandits'' has All-Terrain Armored Combatants (A.T.A.C.s).
* Virtuaroids in ''VideoGame/VirtualOn''.
* ''VideoGame/VoxMachinae'' gives us Grinders, very industrial, Real Robot mining and military mechs, for the player to pilot and slug it out in.
* Golems in the ''VideoGame/WildArms'' series, which have much more in common with HumongousMecha than, well, {{Golem}}s.
* In ''VideoGame/{{Xenoblade}}'', they're called Faced Mechon, or Faces for short. [[spoiler:You later learn that this is meant to differentiate the purely-robotic regular Mechon from those that are piloted by converted Homs.]]
* In ''VideoGame/XenobladeChroniclesX'', the soldiers of BLADE pilot mechs called "Dolls" in the Japanese version of the game, and "Skells" (as in "exoskeletons") in the English version.
* In ''VideoGame/XenobladeChronicles2'', they are called "Artifices."
* ''VideoGame/{{Xenogears}}'' has Gears, while ''VideoGame/{{Xenosaga}}'' refers to them as A.G.W.S. (Anti-Gnosis Weapon System), A.W.M.S., E.S.' and such.
* ''VideoGame/ZoneOfTheEnders'' has two names, Laborious Extra-Orbital Vehicle (or [=LEVs=] for short) and Orbital Frame. The differences are the construction and the level of technology used. Generally, Orbitral Frames make extensive use of the series' AppliedPhlebotinum, Metatron, and are as such almost universally higher-performance than an LEV (the only [=LEVs=] shown to be on-par with an Orbital Frame are hybrids of tech from both, like Leo's [[VideoGame/{{Gradius}} Vic Viper]] in ''The 2nd Runner'').

[[folder:Web Comics]]
* ''Webcomic/GirlGenius'' has Clanks, which are a steampunk version and vary in size from passing-as-a-pocket-watch to roughly-human all the way up to terrifyingly-large. The most common ones are humanoid, but there have also been examples of animal shaped (both normal and mythological) and there was even an entire [[spoiler: circus caravan of trailers]] that sprouted limbs (and/or wings) and brought the pain on some very surprised soldiers.

[[folder:Web Original]]
* ''Literature/BabeRuthManTankGladiator'' uses man-tanks.
* The term is only ever used once, but ''Literature/HyperFightingMachineMarmalade'' officially calls them Mechanical Giants. The words "mecha" or "mech" are still used in text, though, [[JustifiedTitle as shorthand]].

[[folder:Western Animation]]
* ''WesternAnimation/ExoSquad'' calls theirs E-Frames. This was originally short for Exo-Frames, but then the writers found out that ''WesternAnimation/{{Centurions}}'' used the name first, and compromises were made. The fact that the pilots are visible from outside is somehwat of a rarity.
* ''Franchise/{{Transformers}}'' has quite a few...
** First up, Transformers are generally sentient robots that can transform into vehicles and animals, although in [[Film/{{Transformers}} the films]] and ''WesternAnimation/TransformersAnimated'' [[NotUsingTheZWord they're not referred in such words]] (save for the second film, when the former Sector 7 guy calls them that).
** Vehicons are soulless, mass-produced models controlled by a single commander.
** Autroopers are similar, but are each partnered with a girl who can kiss it to merge with it and increase its power. [[http://tfwiki.net/wiki/Autrooper Seriously.]]
** Targetmasters are a type of PoweredArmor that can transform into a Transformer-scale gun.
** Transtectors are (generally) lifeless bodies that must combine with a smaller being, often of the organic variety, to function.
** Headmasters in the American continuity are much the same as standard piloted mechs, with the exception that the mech itself has its own mind and soul, which can cause trouble if the body and the pilot don't get along. In the Japanese continuity, it is simply the fusion a (generally) human-sized robot which forms the head of a Transformer-sized Transtector.
*** The Headmasters in the Japan-only ''Anime/TransformersSuperGodMasterforce'' manga plays like the American version above: the robots' bodies are Transtectors, and the Headmasters are the humans who transforms into their heads.
*** In ''[[WesternAnimation/TransformersAnimated Animated]]'' the Headmaster unit is something else entirely: namely, a robotic head that cuts off other robots' heads to take over their bodies (and can turn into a small full robot in emergencies).
** Powermasters (Western name) and Godmasters (Japanese name) are similar to the ''Masterforce'' Headmasters, but instead of heads, they transforms into the Transtectors' engines.
** Similarly, the Japanese ''Anime/TransformersVictory'' series has Brainmasters, where the smaller driver/pilot becomes the face (and brain) of the larger robot.
* Beyond the PoweredArmor in the ''WesternAnimation/RoughnecksStarshipTroopersChronicles'', there exist the Marauders, relatively small mechs in two forms - ape or chicken. More of a MiniMecha though.
* The giant robots in ''WesternAnimation/{{Robotix}}'' were called, well, robotix. It's a non-pluralizing word.
