->''"...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 [[MagicalGirlLyricalNanoha wand]] (or even [[RobotGirl the Magical Girl herself]], in some settings).

The name used is usually different in just about every series that features HumongousMecha, unless it's 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/{{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.
* ''Franchise/{{Gundam}}'', of course, started all this when they called theirs '''Mobile Suits''' (humanoid mecha) and '''Mobile Armor''' (jet- or tank-like 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... though nowadays the difference is more in whether it's humanoid (MS) or not (MA) [[/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 ''Gaia Gear'' add '''Man Machine''', which look like mobile suit, but with advance technology that's on completely another level.
* '''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).
** The established term for this in sci-fi is a "waldo", or maybe "voodoo control". Whether this is better or worse term is dependent on the beholder.
* '''B'ts''' in ''Anime/BtX'', themed mostly for legendary animals.
* '''Variable Fighters''' (TransformingMecha, with the mecha mode additionally being refered to as a '''Battroid''') and '''Destroids''' (Non-Transforming) in ''Anime/SuperDimensionFortressMacross''. 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.
** ''{{Robotech}}'' mostly uses the same names, although they call the fighters and other human transforming mecha '''Veritechs'''. It should be noted, however, that the series often ''did'' refer to them collectively as "Mecha."
* ''Anime/CodeGeass'' has '''Knightmare Frames'''.
** Joined later in the series by the '''Knight Giga Fortress''', which is essentially a giant flying cockpit with '''KMF''' technology (equivalent to the Mobile Armor in ''Gundam'').
* ''Anime/SoraOKakeruShoujo'' has '''QT ARMS''' (or '''Q'''uantum '''T'''echnology '''A'''dvanced '''R'''einforced '''M'''aneuvering '''S'''hroud) for the main girls, with the '''B.O.A.R''' Ship ('''B'''eyond '''O'''rbit '''A'''zonal '''R'''unabout) 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]]
* ''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 LatAm dub made in LA they're known as "Genies", in the OVA's dubbed in mexico they are just "Gods"
* ''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.
* '''Guymelefs''' in ''VisionOfEscaflowne''.
** Smaller ones were simply known as '''Melefs''' but these never played much of a role in the series.
* ''TheFiveStarStories'' call theirs '''Mortar Headds'''. (No, that's not misspelled.)
* '''Megadeuses''' in ''Anime/TheBigO''. Their pilots are called '''Dominus Megadeus'''.
* ''{{Gasaraki}}'' has one side calling their mechs '''Tactical Armor''', ('''[=TAs=]''') while the other calls them '''(Metal) FAKES'''.
** Not to mention the giant demoic creatures dressed in samurai armor known as '''Kugai''' that both of the above were based on. (though the group that calls their mechs '''FAKES''' refer to the '''Kugai''' as '''Originals'''.)
* '''[=KLFs=]''' and '''[=LFOs=]''' in ''Anime/EurekaSeven''. Stands for '''K'''raft '''L'''ight '''F'''ighter and '''L'''ight-'''F'''inding '''O'''peration respectively.
* Its successor, ''EurekaSevenAo'' refers to its mecha as '''IFO'''s, which is short for '''I'''ntelligent '''F'''lying '''O'''bject. Other [[FlyingCar airborne vehicles]] are referred to as '''FP'''s, for '''F'''lying '''P'''latform
* ''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'''.
* In ''SuperDimensionCenturyOrguss'', the Chiram faction call mecha '''Device'''s.
** The sequel ''Orguss 02'' simply called them '''Armor''' in the original Japanese, while the dub called them '''[[{{Woolseyism}} Decimators]]'''.
* ''SoukouNoStrain'' had '''[=STRAINs=]''' ('''STR'''ategic '''A'''rmored '''IN'''fantry) and '''[=GAMBEEs=]''' ('''G'''eneral '''A'''xis '''M'''otorized '''B'''attle '''E'''xoskeleton '''E'''quipment).
* ''SakuraTaisen'' calls theirs '''Koubu''' (or Kohbu, whichever spelling you prefer); the now-defunct European Star Troupe had '''Eisenkleids'''. The English translation of 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".
* ''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.
* ''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).
* ''{{Flag}}'' merely refers to them as '''Bipdedal Weapons'''.
* ''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.
* ''BreakBlade'' features '''{{Golem}}s'''. Only the titular one is a mech in the traditional sense; modern Golems are more magical / psychic in nature.
* ''Anime/GunXSword'' calls theirs '''Yoroi''', Japanese for "armor".
* ''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.
* ''{{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.
* ''Manga/{{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]]...
* ''InnocentVenus'' has '''Gladiators'''.
* ''Anime/{{Utawarerumono}}'' has the (Eva-like) '''Avu Kamuu''' or [[SpellMyNameWithAnS whatever it's spelled]].
* ''EidoronShadow'' calls them '''Shadows'''.
* ''{{Patlabor}}'' calls them '''Labors''' since they're mostly used for industrial work. The series name refers specifically to police Labors, being a shorthand for '''''Pat'''rol '''Labor'''''.
* ''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.
* ''SkyGirls'' has the '''Sonic Divers'''.
* ''ArmoredTrooperVotoms'' has '''Armored Troopers'''. And '''VOTOMS''' actually stands for '''Vertical One-man Tank for Offense and [=ManueverS=]'''. Or not.
* ''AuraBattlerDunbine'' has '''Aura Battlers''' which are humanoid-type '''Aura Machines'''. It also has the non-humanoid '''Aura Bombs''' and '''Aura Fighters'''.
* ''[[{{Xabungle}} Combat Mecha Xabungle]]'' has '''Walker Machines'''. The titular WM gets the '''Combat Mecha''' due to the fact that dedicated combat WMs are rare.
* ''{{Pluto}}'' by Urasawa Tezuka has Brando using a '''Combat Suit''' in a war and a '''Pankration''' for championship fighting.
* ''Anime/GaoGaiGar'' is a '''[[CombiningMecha Super Mechanoid]]'''; its components are a '''Mechanoid''' and a set of '''Gao-Machine''' vehicles. The related ''{{Betterman}}'' mecha are called '''Neuronoids''' because their power relays and controls are affected by their pilot's nervous systems. The abandoned sequel ''GaoGaiGo'' would have featured a hybrid design referred to as a '''Neuro-Mechanoid'''.
* 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/HeavyMetalLGaim Heavy Metal L-Gaim]]'' also call them '''Heavy Metal'''.
* ''Anime/FangOfTheSunDougram'' has '''Combat Armor'''.
* ''BlueCometSPTLayzner'' refers to piloted models as '''Super Powered Tracers''' and unmanned models as '''Terror Strikers'''.
* 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/GingaHyouryuuVifam'' call them '''Round Vernians'''. While Earthling use the term to classified all mech, the alien actually call them as "machine".
* In ''SpaceRunawayIdeon'', the Buff Clan actually use the term '''Heavy Mecha'''.
* '''Metal Armor''' from MetalArmorDragonar.
* ''{{Megazone 23}}'' has transformable '''Maneuver Slave'''.
* The titular '''Machine Robos''' of the ''MachineRobo'' franchise.
* ''Anime/StarDriver'' gives us '''Cybodies'''.
* ''Anime/BlueGender'' has '''Armored Shrike'''.
* ''{{GunBuster}}'' has the [[RealRobotGenre RealRobot]] '''Machine Weapons''', and the [[SuperRobotGenre Super Robot]] '''Buster Machines'''.
* ''GiganticFormula'' has '''Gigantic Figures'''.
* ''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'''.
* 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/RinneNoLagrange'' has '''Ovids''' (standard-issue mechas) and the '''Vox''' (superpowered ones used by the protagonists).
* The Galactic Alliance in ''SuiseiNoGargantia'' uses '''Machine Caliburs'''. On Earth, they call similar machines '''Yunboroids'''.
* ''Anime/GingaKikoutaiMajesticPrince'' uses '''AHSMB''' devices which means: '''A'''dvanced '''H'''igh '''S'''tandard '''M'''ultipurpose '''B'''attle.
* ''Anime/BuddyComplex'' uses '''Valiancers.'''
* ''Anime/AldnoahZero'' gives us '''Kataphrakts,''' named after the heavy cavalrymen of the Byzantine Empire and ancient Persia.
* ''ShiroganeNoIshiArgevollen'' has '''Trail Kriegers.'''
* ''Anime/M3TheDarkMetal'' has '''MA-Vess'''
* In ''Anime/CrossAnge'', they are called '''Para-mails''' which the cast got the design based on the more powerful '''Ragna-mail'''.

[[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. ('''M'''an-'''A'''ssisted e'''X'''perimental) Armor.
** Warren Ellis' rebooted ''newuniversal'' series reimagined this with the H.E.X. ('''H'''uman '''E'''nhancement e'''X'''perimental) 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 ComicBook/GreenLantern Kilowog.
* Doesn't matter how tall they are or if they're piloted or not, those mutant-hunting robots that give the ComicBook/{{X-Men}} hell are all known as '''Sentinels'''

* ''Franchise/StarWars'' usually calls them '''Walkers''' or '''[=ATs=]''' ('''A'''rmored '''T'''ransports).
* ''Film/TheMatrix'' series has '''[=APUs=]''', standing for '''Armored Personnel Units'''. Though looking at them, 'armored' is somewhat less than accurate.
** A more heavily armored version is seen during "The Second Renaissance: Part 2" in ''Anime/TheAnimatrix''. However, the armor did it little good as it was cut open by a robot's laser and the pilot was forcibly torn out, screaming for help as his arms and legs were still trapped in the suit.
* 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 '''[[ExactlyWhatItSaysOnTheTin 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...
* {{Dale Brown}}'s ''Act of War'' duology had '''CID''' or '''C'''ybernetic '''I'''nfantry '''D'''evice. Other books had a [[PoweredArmor skinsuit]] colloquially called '''Tin Man''', or officially '''BERP''' ('''B'''allistic '''E'''lectro-'''R'''eactive '''P'''rocess), because its inventor has a juvenile sense of humor.
* Mechs in ''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'''.
* ''Literature/WyvernDiary'' calls its war machines '''Battleframes'''. Subverted by the fact that the characters call them mechs anyway

[[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 even seasons that ''don't'' still call 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''.

[[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, no canonical name ever given, versions 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 ''Battle'''Droids''''', but someone ''[[Franchise/StarWars else]]'' held the trademark for ''that'' term.
** Actually, [=IndustrialMechs=] exist. It's just that they are so varied that there really is no one "category" of [=IndustrialMechs=]. You have [=LoggerMechs=], [=LifterMechs=], I mean the list is pretty long (They even have [=CattleMechs=]). They have a partial list in one of the older Tech Manuals.
** That would be the 3025 Tech Manual. Which, because of the Unseen designs, was redone and all the [=IndustrialMechs=] went away for "Star League Era" designs from the even more out of print 2750 TRO. More recent manuals have a short list of some of the [=IndustrialMechs=] you might see modified for battle or in use. (Such as the [=SalvageMechs=] designed to haul damaged BattleMechs back to base.)
** In addition to various sorts of Mechs, both sides also use '''[[PoweredArmor Battle Armor]]''', and the Clans field MiniMecha called '''Protomechs'''.
* The title of ''{{Mekton}}'' is also the default name for mecha in it, though plenty of others exist on a 'verse by 'verse basis.
* ''TabletopGame/{{Warhammer 40000}}'' has ''tons'', enough to spawn the ''Titan Legions'' GaidenGame:
** The Imperium refers to enormous walking war machines as '''Titans'''. Imperial Titans range 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. '''Knights''' are smaller, one-man "mini-Titans" approximately nine meters tall, usually deployed in squadrons based on the feudal households of the Knight Worlds. '''Dreadnoughts''' are MiniMecha about four meters tall, in the Imperium's case piloted by a [[EmergencyTransformation mortally-wounded]] SpaceMarine's life-support sarcophagus.
*** 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).
* ''JovianChronicles'' had '''Exo-Armors''' (battlesuits are referred to as Exo-Suits), and HeavyGear and GearKrieg had '''Gears''' in {{Dream Pod Nine}}'s series of mecha TabletopGames. HG's bigger mecha are called '''Striders'''.
* '''Engel'''s from ''TabletopGame/CthulhuTech'', which have [[OrganicTechnology more in common]] with Evangelions than they do anything else on this list.
* ''BlissStage'' has the '''[=ANIMa=]''', or '''A''' lien '''N''' umina '''I''' nversion '''Ma''' chine. It's not [[EmpathicWeapon literally a giant robot,]] though.
* ''[[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 as of the most recent book.
* ''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 [[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=]'''.

[[folder:Video Games]]
* '''VideoGame/CustomRobo'''
* ''VideoGame/CityOfHeroes'' have the Malta's '''Titans''' (Hercules, Zeus and Cronos class) Vanguard has their '''HVAS''' ('''H'''eavy '''V'''anguard '''A'''ssault '''S'''uit) and the Longbow have their Cataphract (it's equivalent, the Arachnos Heavy Blaster, is a SpiderTank instead)
* ''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.
* '''Virtuaroids''' in ''VideoGame/VirtualOn''.
* '''Wanzers''' (Short for the German: ''Wanderung Panzer'', which means "Walking Tank") in the ''VideoGame/FrontMission'' series.
** Which would be a really bad translation, as "Wanderung" is the word for the group activity. "Wanderpanzer" would be gramatically correct, though "Laufpanzer" would be the actual german term, as it's unlike to be supposed to be a tank that is "going for a walk".
* ''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.
** Interestingly, the term Armored Core is actually a nickname-turned-regular term for the AC. Originally, the units were called '''Armored Muscle Tracers''', or '''AMT's'''.
* The ''VideoGame/{{Gungriffon}}'' series has the '''AWGS''' which stands for '''Armored Walking Gun System'''.
* The ''Videogame/StarSiege'' / ''[=EarthSiege=]'' series has '''[=HERCULANs=]''' ('''Humaniform-Emulation Roboticized Combat Unit with Leg-Articulated Navigation'''), though they're generally referred to as '''[=HERCs=]'''
* ''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.
** In ''VideoGame/{{Xenoblade}}'', they're called '''Face 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/GunparadeMarch'', they're called '''Humanoid Walking Tanks''', or '''HWTs'''.
* '''Franchise/MetalGear'''
** [[ParrotExposition Metal Gear?!]]
** Early Kojima nomenclature (''[[VideoGame/MetalGear1 Metal Gear]]'', ''VideoGame/MetalGear2'' 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 ''VideoGame/MetalGear2'', suggested that the term "Metal Gear" was just an affectionate nickname for Heavy Walkers. ''VideoGame/MetalGearSolid4'' [[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/MetalGearSolid2'' was more of a [[spoiler:submarine.]]
* ''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.
* ''RingOfRed'' (An early Playstation 2 game, not that problem with your Xbox 360) called them '''[=AFW's=]''' (Armored Fighting Walkers).
* In addition to most of the above (i.e.: you may have Mobile Suits, Variable Fighters, ''and'' Arm Slaves in the same universe), ''VideoGame/SuperRobotWars'' also 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).
** SRW is pretty much the king of this. They also have '''Dynamic General Guardians''', '''Elemental Lords''', '''Supermechanical Gods''', '''War Machine Dolls''', '''Assault Dragoons''', '''Assault Scouters''', '''Valkyries''', '''Multi Walker''' and more that we've definitely missed. They invented the terms '''[SuperRobot Genre Super Robot]]''' and '''[[RealRobotGenre Real Robot]]''' to provide a more general term for the units, and when they need an all-encompassing name they just go ahead and call them mechs.
** Although justified in that these names are assigned to them by their ''manufacturers''. Personal Troopers were developed by '''Mao Industries''', the Lion series are manufactured by '''Isurugi Heavy Industries''', the Grungust super robot-types originated from the '''Tesla Leicht Institute''', '''Fremont Industries''' built Assault Dragoons while '''Z&R Company''' develop Valkyries.
** The ''[[VideoGame/SuperRobotWarsGaiden Masoukishin]]'' subseries is a more straight example, with inhabitants of La Gias using {{Magitek}} mecha called '''Masouki''' ("magically-clothed machine", usually translated as '''Elementals'''), and referring to any outside mecha they see by that name. There also exist four '''[[SuperRobot Masoukishin]]''' ("magically-clothed machine god", 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.
* In ''TotalAnnihilation'', the infantry units (which are essentially mechs) are called '''[=KBOT=]s'''.
** Which stands for [[FunWithAcronyms 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 ('''s'''upport) '''A'''rmored '''C'''ommand '''U'''nit.
* The ''OneMustFall'' series of robot fighting games called 'em '''H.A.R'''s (Humanoid Assisted Robots), though most characters in-game still referred to them as just robots or "'bots."
* The SNES game ''{{Battle Clash}}'' called their mechas '''Standing Tanks''' (or '''S.T.''''s for short)
* ''VideoGame/VanguardBandits'' had '''All-Terrain Armored Combatants''' ('''A.T.A.C.'''s).
** Does that remind you of [[Franchise/StarWars something]]?
* ''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.
* ''{{VideoGame/Exteel}}'' has '''Mechanaughts'''.
* Although largely forgotten later on in the series, ''VideoGame/MegaManX'' had the '''Ride Armors'''.
* The old BioWare game ''VideoGame/ShatteredSteel'' had '''Planet Runners'''.
* ''VideoGame/{{Battlefield}} 2142'' has '''Battlewalkers''', or just Walkers for short.
* ''{{PlanetSide}}'' has the '''[=BFRs=]''', fully known as '''Big F--''' err, I mean, '''Battle Frame Robotics''', and nicknamed '''Biffers''' by players.
** And the Mechanized Armored Exo-Suit {{PoweredArmor}}, abbreviated as '''MAX'''
* Pox's [[VideoGame/DestroyAllHumans Big Willy]].
* ''VideoGame/ShogoMobileArmorDivision'' has '''[=MCA=]''', '''M'''obile '''C'''ombat '''A'''rmours.
* ''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.
* '''HOUNDS''' of ''ChromeHounds''. 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}}.
* '''Power Loaders''' in ''PowerDolls'', because these vehicles were built upon, well, [[ExactlyWhatItSaysOnTheTin heavy loader]]'s chassis.
* The mechas in ''VideoGame/ArmoredWarriors'' and ''VideoGame/{{Cyberbots}}'' are called '''Variant Armors''' (also [[SpellMyNameWithAnS misromanized]] "Valiant Armors").
* ''LostPlanet: 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.
* '''Golems''' in the ''{{Wild ARMs}}'' series, which have much more in common with HumongousMecha than, well, {{Golem}}s.
* ''VideoGame/SenkoNoRonde'' has '''Rounder'''.
* ''Bumpy Trot'' aka. ''VideoGame/SteambotChronicles'' has '''Trotmobiles'''.
* ''Metal Fatigue'' has '''Combots'''.
* ''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/{{Half-Life 2}}'' and the Episodes have classic HG Wells tripods known as Striders. However, seeing as Dog ripped the brain out of one in Episode 2 they might not be mecha so much as an engineered organic weapon.
** 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."
* ''VideoGame/FinalFantasyVI'' has '''[[MagiTek Magitek Armor]]''' as the most recognizable, but others exist as well.
* 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).
* ''{{Demonbane}}'' has two types. A mundane '''Destroyer Robot''' and {{Magitek}}-based '''Deus Machina'''.
** [[Series/TheDailyShow "God Machine"?]]
* 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.
* In ''JakIIRenegade'', we have the '''Titan Suit'''.
* ''Metal Warriors'' for the SNES has '''Battledroids'''.
* '''Dolls''' in ''Heavy Nova''.
* ''Metal Brigade Tactics'' calls them '''Vertical Armor'''.
* ''Franchise/StarCraft'': Sometimes used, sometimes not.
** 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 presumably merely "heavy"). 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.
* ''G-Nome'' has the '''Heavily Armored Weapons Chassis''', or HAWC.
* 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.
* ''VideoGame/MadStalkerFullMetalForce'' has '''Slave Gears'''.
* Terran Empire from ''GroundControl II: Operation Exodus'' have '''Combat Striders''' and '''Missile Striders'''.
* ''VideoGame/IronBrigade'', true to its WWI roots (and its former title, ''Trenched'') has '''Mobile Trenches'''.

[[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]]
* 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.
* ''{{Transformers}}'' has quite a few...
** First up, '''Transformers''' are generally sentient robots that can [[ExactlyWhatItSaysOnTheTin transform]] into vehicles and animals, although in [[Film/{{Transformers}} the films]] and ''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 ''TransformersMasterforce'' manga plays like the American version above: the robots' bodies are '''Transtectors,''' and the Headmasters are the humans who transforms into their heads.
*** In ''[[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 ''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.
