- Chicks Dig Giant Robots, Opening Theme of Megas XLR

This item is available from the Trope Co catalog

Who needs an Abrams tank when you can have a 100-foot man-shaped robot with a glowing sword and a fist that fires off like a missile? There's no argument - fighting robots are just infinitely cooler than ordinary vehicles. Whatever their shape, though, they are all known as "mecha".

The "mecha", or "giant robot", concept is ubiquitous in Japanese pop culture, and is more than adequately represented in Anime. Despite the name, the robots need not actually be "giant" - some are merely human-sized, and some even smaller. Mecha themselves usually divided between the "Super Robot Genre" and the "Real Robot Genre", the distinction typically being where they belong on the Mohs Scale of Sci Fi Hardness, though there are as many different kinds of settings for mecha as there are genres.

The giant robot genre is considered to be the creation of Mitsuteru Yokoyama, creator of Tetsujin #28 (Gigantor) and Giant Robo (Johnny Sokko and his Flying Robot). Both of these featured the early trope of The Kid with the Remote Control. The genre was further defined and refined by Go Nagai. His Mazinger Z (Tranzor Z in the United States) holds the distinction of being the very first piloted giant robot. In that series and others (Getter Robo, UFO Robo Grendizer, etc.), Nagai singlehandedly invented nearly every classic trope of the Super Robot Genre: the rocket-fist, the blazing sword, the amazing entrance from a secret launch bay, and the first transforming and combining robots.

Yoshiyuki Tomino (Brave Raideen, Zambot 3, Combattler V) started out emulating Nagai. Wanting to write a serious war story but under contract to crank out robot anime, he finally said "let's watch both!" and created Mobile Suit Gundam, the first step toward the Real Robot Genre. In its wake, such series as Dougram and VOTOMS refined the concept with robots that looked as though actual military people had designed and built them. Macross, in this context, was merely the first anime to come up with transforming robots that still looked like reasonable examples of military hardware.

Mythology as a whole is also replete with artificial humans and similar automatons (eg. Talos, the great bronze automaton built by Hephaestus), but special mention goes to Hindu Mythology. One of the three barriers the gods set to protect their elixir, the Amrita, was a robot with rotary saws for hands.

In more "realistic" works, such variations as the Spider Tank and Powered Armor are more common.

See also Combining Mecha, where the mecha is comprised in turn of smaller mecha or vehicles, and Transforming Mecha, where the mecha transforms to and from another form. If a mecha is small but still piloted as opposed to "worn", it's a Mini-Mecha; otherwise, see Powered Armor. Walking Tank is simply a bipedal tank with no humanoid design. Spider Tank is a variant which replaces humanoid and animal configurations with an insectile design.

Anime and Manga
If we forget about the question how they actually work, their combat efficiency is not shown as overwhelming (unless using even more ultra-high tech), unlike most examples. In the first episode of the anime taking out Hind helicopter is seen as a show of great mastery, and later, a single tank is designated by AS on-board AI as a serious threat.
 * Tetsujin #28, or Gigantor as it was originally known in North America, was probably the first "giant robot" anime imported to the United States. This black-and-white series was aired during the 1960s in many markets.
 * Go Nagai's Mazinger Z was the first series to feature giant robots piloted by humans, the convention which came to define the entire genre. It also created the Super Robot Genre as we know it, featuring, if not originating, many of the tropes that have come to be associated with the genre. The series, along with sequels Great Mazinger and UFO Robo Grendizer, have been aired worldwide.
 * The caption for the page image is in fact a good example of Hilarious in Hindsight. Go Nagai, trying to come up with an idea for a giant robot story that wouldn't rip off Tetsujin, was observing a gridlock one day when he mused to himself that the drivers in back must be wishing for a way to bypass those in front. From that idle thought came the concept of a man-driven robot, and the rest is history.
 * The Gundam metaseries launched the Real Robot Genre, and its dozen or so sequels, prequels, and Alternate Universes refined it perhaps more than any other series. The original series had Transforming and Combining Mecha, due to its Super Robot Genre roots, but these were retconned out in the movies. Mobile Suit Zeta Gundam brought back Transforming Mecha, and its immediate sequel, Mobile Suit Gundam ZZ, features a new Combining Mecha, the modular-design ZZ Gundam.
 * In Gundam Wing, a bit of Justified Trope goes on for the humongous mechas in the series where Lt. Noin explains that the advent of the mechas came about when the Alliance wanted a physically intimidating weapon.
 * Technically, both Transforming Mecha and Combining Mecha have been in most Gundam shows. Gundam, ZZ Gundam, V Gundam, V2 Gundam and Impulse Gundam all use the same principle, with being module based and all. Freedom and Justice can both combine with the METEOR Units, and Exia and Dynames both have the GN-Arms Type-E and Type-D respectively. 00 Gundam also had the 0 Raiser and Arios had the GN Archer. In the Gundam 00 Movie, the large backpack on Raphael Gundam turned out to be an upgraded Seravee Gundam, transformed into a giant weapons-platform.
 * As for Variable Mobile Suits, the Z Gundam, ZZ Gundam, Methuss, Re-ZEL, Re-GZ, and a lot other UC Suits qualify. Also, the Wing Gundam, Wing Gundam Zero, Airmaster, Airmaster Burst (the latter two from Gundam X), Aegis, Murasame and Savior (from Cosmic Era (SEED and SEED Destiny)). And Kyrios/Arios/Harute and Gadelaza, Regnant, Empruss, GN Archer, Flag (and variants) Enacts, Hellions, Realdos and Reborns Gundam/Reborns Cannon are all Variable Mobile Suits from 00. And there are probably some that were left out.
 * For truly Humongous Mecha, see the Psycho Gundam and Destroy Gundam. Both are 400 tonne Weapons of Mass Destruction that more or less serve as mobile tactical nukes.
 * Super Dimension Fortress Macross features some of the earliest transforming mecha, with the Valkyrie jet/space fighters that could turn into humanoid robots and a hybrid semihumanoid/semijet ("gerwalk") form. The Macross itself was a huge spaceship that could rearrange itself into a pointlessly humanoid configuration.
 * When SDF-1 performed Hypespace Fold at the beginning of the show, it's fold drive mysteriously disappeared along with a chunk of other machinery and major powerlines. So, the whole point of Modular Transformation was to reconnect Macross Canon to the power supply.
 * This, however, was completely ignored in the following series on the same universe, and "Macross" type spaceships always have to transform into some pointless humanoid form to fire their main gun. Rule of Cool all the way.
 * Macross Frontier doesn't always follow this, however. Both the Macross Quarter and Battle Frontier are seen firing their primary weapons while in "ship" mode.
 * The humanoid configuration also allows the capital ships to use the Macross Attack without compromising the firepower, safety, or maneuverability of the entire ship.
 * It was intercut and dubbed with with Mospeada and Southern Cross by Carl Macek to create the frankenseries that is Robotech.
 * Another mech that's particularly iconic to the series is the Destroid Monster, which has an appearance and speed that wouldn't look out of place in BattleTech.
 * Which itself can be considered as not looking out of place because in the early pre-1995 versions of Battletech, various mecha there were licensed from anime, including Macross.
 * Getter Robo, the first transforming and Combining Mecha, which also features some of the most humongous mecha in the medium. The mecha progressively increase in size and ridiculousness over the series, ending with the Getter Emperor which.
 * On the other hand Freeder Bug, also created by the late Ken Ishikawa has some of the least humongous Humongous Mecha in anime or manga, not counting power suits. They're essentially just heads with stumpy limbs and a chair fixed to the back, and are smaller than an adult man.
 * Giant Robo is a descendant of a 1960s live-action series brought to the U.S. as Johnny Sokko and His Flying Robot.
 * Subverted in 20th Century Boys. The Big Bad, Friend, holds a robotics engineer hostage so that he can construct a fifty-foot giant mecha to use on the Bloody New Year's Eve. However, throughout the brainstorming process, the aforementioned engineer is on the verge of snapping because he can't get them to understand that a robot constructed in such a way probably couldn't even stand, much less cause massive havoc and destruction.
 * Nevertheless, the final arc plays this straight when said robotics expert finally succeeds in making a working one. It's kind of justified in that by then it's been about years since the first time.
 * Gasaraki attempts (amidst an incomprehensible mass of mysticism) to show a "realistic" view of giant war robots in a contemporary setting. The "Tactical Armors" of Gasaraki are not much larger than a main battle tank, require extensive support squads, and can have their joints fouled by blowing sand.
 * Infinite Ryvius subverted this by having the characters burst into laughter when they first saw a giant humanoid robot because it seemed so impractical. Needless to say, they were proven wrong.
 * Full Metal Panic, like Gasaraki, attempts to show "realistic" robots in a "modern" setting, but is considerably more relaxed about what constitutes "realistic", not to mention much lighter-hearted. It also acknowledges that man-shaped robotic fighting machines are at the very least unlikely, but promptly handwaves the objection away with a mysterious source of ultra-advanced technology.
 * As Neon Genesis Evangelion is both a subversion and a Deconstruction of the Humongous Mecha genre.
 * Jet Alone is this trope played straight.
 * Parallel Trouble Adventure Dual gently parodies Evangelion and giant robots in general while still having an upbeat and entertaining plot. It features an Ordinary High School Student who gains The Unwanted Harem when he turns out to be the only male capable of operating a "Core Robot", an apparent real robot, but later updates to a super robot similar in appearance to the mecha of Escaflowne.
 * Eureka Seven also uses mecha similiar to Evangelion, where the mecha are more than simple robots. The LFO and KLF units, as they are called, have a form of sky surfing applied to their operation. Additionally, the units are Transforming Mecha, as most can change into land vehicles.
 * The immensely popular Martian Successor Nadesico not only features a battle mecha class called the "Aestivalis", but also incorporates a 1970s-style Super Robot Genre anime called Gekiganger 3 as a Show Within a Show. "G3" is a clear homage to the early classic Getter Robo, and manages to hit all the classic melodramatic cliches of the genre.
 * The popular Japanese franchise Sakura Taisen employs not-so-Humongous mecha (only about 10-12 feet tall), powered entirely by steam (and empowered by the pilots' psychospiritual ability, or "reiryoku"). The mecha fight demons and evil spirits who, in turn, pilot their own appropriately evil steam-powered robots. The franchise's mecha are entirely super, though, with a whole list of named super-moves and various highly improbable weapons, including a revolver, gun-barrel sword, and giant psychically animated teddy bears.
 * Patlabor is likely the most feasible Humongous Mecha anime, featuring short, non-combat robots used for civilian purposes such as construction. The only combat robots belong to the protagonists, the police, who prevent mecha-related crimes and the military, like the Japanese Self-Defense Force.
 * Soukou no Strain, which, though it may not be what it seems, is certainly about mecha pilots.
 * Utawarerumono has a nation composed of a religious minority who have giant mecha given to them by their god to defend themselves. Considering the rest of the world hasn't even invented gunpowder, this is probably overkill.
 * Tenchi Muyo!! GXP:
 * The leaders of the Nobuseri bandits in Samurai 7 are massive cyborgs, with swords the size of houses.
 * Sky Girls contains about every cliche in this trope, including female pilots wearing extremely skin-tight and revealing g-suits.
 * Tengen Toppa Gurren Lagann takes the "humongous" part to ridiculous extremes, with each incarnation of the main mecha being piloted by the smaller mecha. The show starts with the Mini-Mecha, Lagann, which was discovered by Simon. After Kamina hijacks an enemy mecha, which he names Gurren, he combines it with Simon's Lagann to form the regular sized (by mecha standards) Gurren Lagann. Simon uses Lagann to capture Thymilph's Dai-Gunzan, an enormous mecha/warship, which is renamed Dai-Gurren and serves as the base of Team Dai-Gurren. After the Time Skip, Team Dai-Gurren acquires the Arc Gurren Lagann, which is about the size of a city. Then the moon turns out to be a huge starship which is transformed into the appropriately moon-sized Super Galaxy Gurren-Lagann. Finally, in the Final Battle, . The second movie, Lagann-hen, does takes it to the next level, but  In other words, if you like humongous mecha, this is basically porn for you.
 * Gunbuster and its sequel Diebuster have Mecha even more Humongous than most- Gunbuster is hundreds of meters tall, and Diebuster is approximately the same height as the Earth itself.
 * Probably worth noting that Gunbuster and Diebuster were made by the same studio as Gurren Lagann. In fact the Tengen Toppa Gurren Lagann was probably partly to upstage the Diebuster, which in turn upstaged every other Humongous Mecha that came before, except maybe Unicron.
 * The Xephon from RahXephon, although obviously and definitely not mechanical, follows many of the genre's tropes to a T.
 * The Rune Gods in Magic Knight Rayearth take form of not just beastly creatures, but also Humongous Mecha based on those said creatures.
 * This funnily creates a fan-wishing to include Magic Knight Rayearth in Super Robot Wars, despite the difference in theme of story. Well, who wouldn't want to see Rayearth teaming up with, say, GaoGaiGar?
 * All of the Humongous Mecha that Team Rocket wields in the Pokémon anime. One has to wonder where they get the money for all those giant robots, considering that they're both deep in debt and far out of favor with their boss...
 * In one episode in the Diamond and Pearl series, it was noted that Team Rocket stole various parts from a factory, which they used to build that episode's mecha. That seems to help keep their expenses down.
 * They also occasionally mention buying cheaper "build-it-yourself" mechas online, especially in the Johto story arc. That's one explanation for why most of the mechas have at least one glaring weakness.
 * Played with in an episode of Wolf's Rain in which the wolves accidentally reawaken an ancient defensive mecha while making their way through a ruined city.
 * The main villains in Scrapped Princess are capable of transforming into Humongous Mecha. They are forced to use power limiters to maintain a normal human guise until they are authorized to carry out their mission.
 * Mecha are part of the central conflict in Code Geass. A one-sided war was won with them, and now they're being used to reclaim the country from The Empire. And in a case of Fridge Brilliance, dodges the whole too-vulnerable-to-having-it's-legs-shot issue by adding landspinners, making the mechas too friggin' fast to target their legs accurately. Or in the case of the Lancelot, target the whole mecha accurately.
 * Though most of them are Mini-Mecha, each only being a few meters tall. The truly humongous mecha are Knight Giga Fortresses like Siegfried (which is really the only one) which is 5 times as tall as most mecha in the series, and 8 times as heavy, but is less a robot, and more a flying spiked ball. Gawain is the largest true Knightmare Frame, but is only 6.5 meters tall, when most Knightmares are 4 to 5 meters.
 * In Gad Guard, the mecha aren't piloted, per se. Rather, the person they "belong to" rides around on their shoulder, or some such. While some of them occasionally give their mechs orders (especially the villain), they tend to act on their own. In battle at least...
 * The Armor Troopers from VOTOMS (Verticle One Man Tank for Offense and Maneuvers) are perhaps among the most perceivable (combat based) humongous mecha in real life. They are no taller than 4 meters, do not transform, don't fly, and generally don't have any unique powers. They are more like bipedal tanks than anything else.
 * See also many of the other series created by Ryosuke Takahashi, such as Dougram and SPT Layzner. While they're not as realistic as VOTOMS, they are compared to the majority of mecha shows and have a similar gritty atmosphere.
 * Not to mention that the protagonist builds an AT from scrap parts several times over the course of the show. They're repeatedly shown as disposable and cheap.
 * Geneshaft has a very weird mecha, which looks more like a set of cranes welded together to vaguely resemble a human outline. It is also totally unclear why it should look remotely human anyway, given its function in the story.
 * Funnily enough, Saber Marionette J parodies this when the Imperial Palace eventually transforms into a Giant Robot, who is then used to attack and stop a Giant Bomb.
 * The Brave Series franchise is a series of mecha shows each starring a different Super Robot and their respective crews. They will often feature a pair of main characters, rather than a single one (usually a young boy and a grown man, who often serves as a big brother feature). By far the most famous of these is The King of Braves GaoGaiGar, a series which managed to recapture the feel of fun and Hot bloodedness of mecha from the 70's amidst a wave of Darker and Edgier mecha series in the wake of Evangelion. Also had a sequel OVA a few years later which managed to be of better quality (especially the fight scenes!) than most series of its kind. And even that proved so popular it got a special edition just five years later, linking it to Betterman, a much different kind of mecha show from the same company. Also, had a brief Follow the Leader series, Brave Police J-Decker, which featured sentinent, non-piloted robots a la Transformers.
 * The Big O puts Victorian-looking giant robots in a creepy retro-future film noir setting reminiscent of Batman the Animated Series.
 * Ramrod from Saber Rider and the Star Sheriffs.
 * Dai-Guard turns its focus on the giant robot's pilots and all of the red tape they have to cut through to save the world.
 * The robots from Bokurano are freaking enormous. Zearth is half a kilometer tall, and is estimated to be able to destroy the entire military forces of the U.S. in two days. They are also piloted by untrained, inexperienced children which isn't silly as you thought...
 * Each of the different nationality random girls in Rizelmine has one, each almost more ridiculous than the last.
 * The mecha in Irresponsible Captain Tylor seem to be specifically designed to subvert the "Humongous" part of this trope, in fact most of their pilots are huge and shown to be very cramped inside their mecha. The big butch leader is in a pink one. The general design of the mecha is similar to the squat egg-shaped ones found in Sakura Wars.
 * Even a series like Mahou Sensei Negima has them (maybe the series is just like that). They were created using the Proto Type data from a sealed demon god.
 * (Much) Later on, Haruna uses her artifact to create a life-size robot body for Sayo. Of course, Sayo can only use the robot body by possessing a small voodoo doll and climbing inside the robot body and piloting it Humongous Mecha style.
 * Zoids manages to buck the trend in giant robots by having its eponymous robots patterned after nearly every animal imaginable except humans. This ranges from tractors shaped like beatles to flying battleships that look like whales. A recurring theme through the various editions of the franchise is that the hero tends to pilot a Zoid based on a large feline (usually called a "Liger"), while his rival pilots a robotic dinosaur.
 * In Project A-ko B-Ko creates these although she is perhaps better known for her Bikini Battlesuit.
 * Busou Renkin has an example in the form of Great Warrior Chief Shosei Sakaguchi's Busou Renkin, Buster Baron, which resembles a 57m knight armed with a pair of knuckle dusters and a jet pack and is capable of using giant forms of the Busou Renkin of alchemy warriors who are riding in it.
 * The eponymous Escaflowne is a 20-something-foot-tall Magitek mecha that can transform into a dragon-mech.
 * Zettai Muteki Raijin-Oh, the first of the Eldoran franchise, is a Transforming Mecha-slash-Combining Mecha piloted by untrained, inexperienced children. This concept would be later taken up in the later series, Genki Bakuhatsu Ganbaruger and Nekketsu Saikyo Gosaurer.
 * In a MAR Filler arc, a trio of sisters can summon their mecha 'Rotkappchen Waltzer'.
 * Those with ghost AR Ms can themselves be considered human-sized mecha as well, as they combine with the person.
 * The Deucalion(Mecha Form) in Kiddy Grade. Just watch the last 4 episodes(and mind the statistic of the Deucalion) then you'll understand why.
 * 65.000 fucking kilometers (which should actually be 65 fucking megameters) in length. You can't go wrong with that.
 * Until you need to find a place to keep the thing.
 * The Cybodies of Star Driver are Motion Capture Mecha that can be operated only by their chosen drivers, who are marked.
 * The eponymous mecha of Galactic Whirlwind Sasuraiger.
 * One appears in Moonlight Mile. It's tested underwater first to prevent the dangers of it falling over.
 * Hanaukyo Maid Tai. In one episode Ikuyo Suzuki demonstrates her latest creation: a giant robot resembling the Loch Ness Monster.
 * Zeorymer.
 * Gaiking.
 * Voltes V.
 * Kotetsu Jeeg.

Comic Books

 * X-Men has the Sentinels, mutant-hunting Humongous Mecha. They started out small (when compared to Evangelion, Super Sentai, etc.) but worked their way up to standard mecha size. Much worse (in terms of design impracticality) is that they were created in a "Master Mold," which is actually a much larger Sentinel. Since AI Is a Crapshoot, Sentinels are known for getting out of their creators' hands in short order (Especially Master Molds, Sentinel-shaped factories which wouldn't need any decision-making ability.) The Literal Minded A Is in fact point out their creators' fallacies - "Hunt mutants? You do know that humans are mutant monkeys, right? Humans are mutants."
 * It seems the government types finally learned their lesson, because lately, Sentinels tend to be standard Humongous Mecha - Sentinel-shaped vehicles piloted by humans. One character points out the irony when some of those human-piloted Sentinels are assigned to protect mutants; "It's like a black man being protected by a burning cross."
 * Does anyone remember First Comics' Dynamo Joe? (Sometimes scripted by Phil Foglio.)
 * The BGY-11 of The Big Guy and Rusty the Boy Robot is secretly a humongous mecha; the world at large and Rusty in particular assume that it is a sentient robot, and maintaining this secret complicates several episodes.
 * Back when Marvel had licenced Godzilla as a character, they also created the Red Ronin giant robot to fight him. Godzilla has faded away from the Marvel Universe, but the Red Ronin still shows up. Occasionally.
 * In Earth X, Tony Stark has secretly redesigned the Red Ronin into a Transforming Mecha that spends most of its time as his "Iron Avenger" factory. We don't know this till the end of the story (making Tony appear to be a useless recluse), when he pilots it into battle against the even larger Celestials, who are energy being versions of the same--their energy bodies need Humongous Mecha to give them shape.
 * Iron Man also built one to fight Megatron in a crossover between the Avengers and Transformers. He also has his various designs of the Hulkbuster armor which approach this trope and War Machine's satellite turns into this trope.
 * Marvel also, for a short time, ran a Shogun Warriors comic, featuring the Super Robots Combattler V, Brave Raideen, and Dangard Ace
 * Kazu Kibuishi's Amulet
 * Warren Ellis' Tokyo Storm Warning.
 * The Man-Robots from the Disney Comics story "The Giant Robot Robbers" by Carl Barks.
 * Jack Hawksmoor of The Authority can actually turn cities into Humongous Mecha. As in, walk into the middle of Tokyo, ask it very nicely, and come out wearing battle armour made of concrete and skyscrapers.
 * The Guardians in Doug TenNapel's Gear.
 * Nothing quite like mecha being piloted by anthropmorphic cats who look like they could have easily been extras on Steamboat Willie
 * Doug TenNapel seems to like this trope, because he used it again in Ghostopolis, where
 * In the Crapsack World of the Kingdom Come series, an aged Batman fielding an entire army of computerized mecha is the reason why Gotham City, along with the Flash's Keystone City (constantly patrolled by the Flash at ultraspeed), are the only two really safe places for a normal human to live.
 * Though rare, giant robots do show up on occasion in Judge Dredd. The majority are from Hondo City, appropriately enough.
 * Whether S.T.R.I.P.E. is a Humongous Mecha or a suit of Powered Armor depends on the writer and the situation, although it started out as a Humongous Mecha in the Stars and Stripe series.
 * In SHIELD Infinity, the Colossus of Rhodes was a Humongous Mecha, piloted by Archimedes to battle a Kree Sentry.
 * In the Crapsack Future of Give Me Liberty, the "Fat Boy" fast-food chain uses a humungous mecha mascot in their war to raze the Amazon rainforest into farmland.

Commercials

 * Several advertisements for the Citroën C4 feature the car transforming into a Humongous Mecha.
 * There's also a Singapore Army ad featuring a Navy Cruiser Transforming Mecha. Now that's what I call firepower!
 * In the same spirit as the Singaporean ad, this commercial for the Republic of China's army basically promises recruits that they'll get to ride mechas to combat.
 * One Vonage ad showed a man using his laptop to pilot the walking machine he was riding, which consisted of an armchair and two stilt-like legs.

Film

 * Spaceballs has Spaceball One/Mega Maid, which is apparently so big it can take the entire atmosphere of a planet. It is also a Transforming Mecha.
 * The Star Wars AT-ST's and the AT-AT's are among the most visually distinctive mecha in popular culture.
 * And then there's the Transformers: Crossovers toy line which features an AT-AT which transforms into a giant robot.
 * In Canon: AT-AT's actually move close to 60KMH. They look slow, but the 12 tons of mecha doesn't slow or stop easily. Remember when Luke caught one, he got jerked off his feet.
 * The AT-TE seen in Attack of the Clones, despite being "older" technology, has a much more sensible beetle-like design, with six legs and a low profile for stability.
 * The explanation is that the AT-TE was far to vulnerable to mines, being only a few feet off the ground.
 * And remember, AT-ST soccer games are strictly against Imperial Army proctocols (668).
 * The live-action Transformers movie series, also played straight with Transforming Mecha.
 * Mechagodzilla and Kiryu from the Godzilla series. There are also Mechanikong, MOGUERA and Jet Jaguar (though Jet Jaguar doesn't start out humongous).
 * Special mention should go to Mog(u)era, alien terror weapon of the eponymous villains in the 1957 film The Mysterians (Chikyū Bōeigun). It appeared on the big screen a mere year after Tetsujin-28 was first published and a full six years before the anime, and showed up again 37 years later in Godzilla vs SpaceGodzilla.
 * Most of WALL-E's robots are smaller than the average human (let alone the obese humans of the future), but at one point we meet two giant versions of the eponymous trash compactor robot.
 * The Iron Giant The title says it all.
 * Matrix: Revolutions: Humanity fights off a flood of enemy machines with 20' tall humanoid mecha. Hilariously, the pilots are almost completely exposed in the suits, making them pretty worthless once the machines get close.
 * Word of God said that even with the armor, the machines tore through it like butter, meaning there was no point it keeping it there if it was just going to be useless anyway
 * Robot Jox was a low budget western attempt to exploit this genre. In a dystopic future, wars are resolved by duels between two giant mecha, much like a sporting event.
 * Aliens: Ripley in the Power Loader, leading to a Crowning Moment of Awesome.
 * Similiar in size to Aliens' Power Loader, but far more militarized, were the AMP Suits from Avatar, from the same director. With a giant freakin' mecha combat knife equipped. Colonel Miles Quaritch used one in the final battle for The Tree of Souls.
 * The climax of District 9 features a rampage by a highly mobile, heavily armored and DEVASTATINGLY well armed Mini-Mecha in the main character's Crowning Moment of Awesome.
 * A rare, non-humanoid example: in the 2005 version of War of the Worlds, it's revealed that the aliens piloting the giant tripods look like human-sized versions of their death machines, making them the extraterrestrial equivalent of humongous mecha.
 * A giant Transforming Mecha appeared in the latest Terminator movie.
 * The climax in We Are the Strange has a giant mecha fighting a giant monster.
 * There is a giant robot that guards the gates to the Goblin City in Labyrinth
 * The monstrous heroes of Monsters vs. Aliens face villain Gallaxhar's enormous Robot Probe. The Probe withstands a military strike and destroys half of San Francisco in its conflict with the monsters before being destroyed by Ginormica. It's later revealed that Gallaxhar has an entire army of Robot Probes at his command, but when he orders them to destroy Ginormica, they end up smashing into each other like dominoes.
 * The Incredibles: The bad guy makes giant robots to destroy all the Supers, improving his design each time a super manages to destroy one.
 * The Destroyer from Thor.

Literature

 * Empire, by Orson Scott Card.
 * Built in secret by evil liberal pacifists to slaughter U.S Service personnel out of naked hatred for American men-in-uniform, no less.
 * The Star Wars Expanded Universe, again, features lots of big walking war machines aside from the AT-AT and AT-ST models.
 * Perhaps, collectively, the in Making Money.
 * Moist also introduces the idea of thirty foot killer golems, since "If you don't invent thirty-foot killer golems first, someone else will".
 * The Sholan Alliance Series has a unique version featured on the cover of the eighth book. Apparently, it is also given some page time.
 * William Keith's Warstrider series.
 * The Martian machines from The War of the Worlds. They practically founded the genre.
 * If The War of the Worlds is almost certainly one of the key Trope Makers.
 * The Evil Librarians of the Alcatraz Series has giant robots as part of their army, as well as flying robotic bats known as robats.
 * Older Than Dirt: Parts of the Sanskrit Rig Veda appear to describe air-to-air missiles traded between flying mecha and floating cities.
 * Most of the books by John Ringo have these.
 * Dangerous Fugitives subverts this by having giant animal robots instead of giant human ones.
 * Deconstructed by a simulated Humongous Mecha battle that takes place between two diplomats in the Dream Park novel The Barsoom Project. Their battle is staged in the middle of a simulated city, complete with tiny terrified civilians who die in droves every time the robots make a move, as a psychological ploy to get the bickering diplomats back to the negotiating table.

Live Action TV

 * In live-action, giant transforming and combining mecha have been a staple of the Super Sentai franchise since its third installment, Battle Fever J, having borrowed the concept from a live-action Japanese adaptation of Spider-Man. Yes, that Spider-Man.
 * Later installments of the franchise (from Kyoryu Sentai Zyuranger onwards) would be adapted into Power Rangers, which terms all its mechas as "Zords" and the combined forms "Megazords".
 * The absolute biggest would have to be Daijinryu/Serpentera. To make it clear: Dairenoh/Thunder Megazord is 54 meters tall and Daimugen/Tor the Shuttlezord is 95 meters. Daijinryu/Serpentera is 500 meters long and 345 meters height when standing. We once got a distant shot of Serpentera standing in the city, and buildings were about the size of one claw. If it were to lie down, its head could be downtown and its tail could be in a suburb. In franchise history, its size has yet to be topped.
 * Doctor Who had a  in the 2008 Christmas special.
 * The K-1 robot from Robot eventually grew into one of these?
 * Double the Fist gives us the shortlived Depot in Series Two.
 * The Swiss-army knife that is Drago from Superhuman Samurai Syber-Squad, which manages to fit every category (excpet 'mini...' but then again, they're inside computer systems, so maybe it counts, too!) It can transform from plane to dragon and back, combine with Servo to make Phormo, split to make Tor and Jam, and Jam alone can transform into the Dragon Cannon to be used by Servo. The toy probably had to be a freakin' jigsaw puzzle.
 * If anything, its counterpart, Xenon, was the jigsaw. Vitor folded about 8 billion different ways depending on whether you wanted it in jet form, Xenon form, or Synchro (Servo combination) form. Borr, the Drill Tank, split into 4 different parts to make Synchro's shoulders/fists, and to change Tracto from Xenon's legs to Synchro's you basically had to turn it inside-out. Adding insult to injury was the fact that not only that did its Xenon form hate staying together, but that it looked like a really lousy Optimus Prime knock-off.

Newspaper Comics

 * Dick Tracy had TRAZE-R, a thirty-foot high robot Dick Tracy that fought an enemy robot to the death. Like everything else about Dick Tracy, TRAZE-R was absolutely bugnuts insane.
 * Brick Bradford faced a remote-controlled robot about ten stories high in Brick Bradford and the Metal Monster (02/13/1939–03/16/1940).

Music

 * Parodied in the Beastie Boys' "Intergalactic" video.
 * The video for Jason Forrest's 'War Photographer' features a pair of humongous mecha. That transform out of giant robots. Crewed by vikings. Who battle it out with the power of rock and roll. No, seriously. And you know what? It's awesome.
 * Linkin Park's video for "Pts.OF.Ahrty" features CGI Humongous Mecha, each of which is based on the band members. So if the trope wasn't Awesome but Impractical enough already, you have one that's as skinny as the lead singer.
 * There are also the videos for "Somewhere I Belong" and "New Divide".
 * Whore Moans and MC Frontalot have a song, "Mecha Mechanic", that is an ode to a giant robot.
 * An army of giant robots is Doctor Steel's back-up plan for world domination, if the whole "domination through entertainment" idea doesn't pan out.

Tabletop Games

 * The classic western Humongous Mecha RPG is Mechwarrior, the role-playing side of the BattleTech tactical miniature games. Both series feature everything from 3-meter tall battle frames to hulking 25-meter tall Humongous Mecha, and even had Transforming Mecha before their botched design licensing contract fell through with Harmony Gold. Originally created by FASA Corporation in 1984, it was sold to Wiz Kids in 2000, and has been owned since 2003 by Topps.
 * Possibly the weirdest Humongous Mecha RPG is the Dungeons and Dragons-based Steampunk/Magitek crossover Dragon Mech.
 * Combining Cthulhu Mythos, Macross, Guyver and Neon Genesis Evangelion, you get Cthulhu Tech. Irony, while it's even more weird than Dragon Mech, it has too much Captain Ersatz and thus not as unique.
 * Exalted's Warstriders.
 * Also, high-Essence Alchemical Exalts...until they turn into cities.
 * Also also Hellstriders. They're made of demons.
 * Every race in Warhammer 40000 has at least one type of giant mech, though the Tyranids' uses Organic Technology; the sizes grow from Space Marine Dreadnoughts and Tau Battlesuits about thrice as tall as a man to at least 150 foot tall (the accounts contradict each other; some claim the heights go all the way up to 2km) Emperor-class Titans mounting cathedrals, housing a full company of troops in their legs and able to pull ground-to-orbit duty against enemy spaceships. It is said there are mechs large and powerful enough to metaphorically mop the floor with even Emperor-class Titans...
 * It's been said that an Emperor Titan, built to scale with the actual Space Marine figures, would be the size of a 10-year-old. Anything large enough to take down an Emperor is probably large enough that if a model was ever made, with a bit of work with power tools you could wear it to a tournament.
 * It should be noted that the Imperial Guard has specialist tanks designed for anti-Titan work. Shadowswords are armed with a Volcano cannon, which is itself a Titan gun. Titans are somewhat less impressive when a tank on the ground vaporises one of its knee joints...
 * Here's a size chart for the most popular huge Ork vehicles. This is only a guideline, not a limit.
 * Even Dungeons and Dragons gets in on the act with the Eberron campaign setting. The warforged are a playable race. Their "ancestors"--or more accurately, prototypes--called warforged titans, are not.
 * Some golems can get pretty humongous, as well, in particular the iron, mithral, and adamantine golems. However, the biggest autonomous constructs are undoubtedly the colossi, 100-foot tall humanoids of stitched flesh, hewn stone, or cast iron, only ever created by the mightiest wizards.
 * Dating back the the first edition Dungeon Master's Guide is the Mighty Servant of Leuk-o, something of a giant mecha which is controlled from a cockpit containing something like one hundred unlabelled levers, each with a different function.
 * Also in old D&D, an obscure module called "Earthshaker", which was set in and around a gigantic dwarf-crewed robot.
 * D&D's sister product, D20 Modern goes for the direct route. The magazine supplement Mecha Crusade puts forth options for mecha that go from large Powered Armor all the way to true Humongous Mecha (or, in game parlance, "Colossal Mecha"). These rules were later touched up slightly (the highlight being conversion to D20 Modern's built-in economy instead of the clumsy level-based Point Buy System used by Mecha Crusade) and included as an entire chapter of D20 Future.
 * Heavy Gear, which features smaller robots than BattleTech's average, but which are definitely more than just body armor.
 * Rifts features a wide variety, from the Triax Devistator which can step on things up to the size of a two-story house, to designs such as the Ultimax and Terror Trooper which stand about twice the height of a man and blur the line between powered armor and mecha.
 * And the famous Glitterboy, which is fairly small for a mecha but has to use built-in drills to secure itself to bedrock in order to not fall over from firing its ground-to-orbit "Boom Gun" railgun.
 * GURPS Mecha gives players the wherewithal to design and build just about any of the above concepts every example on this page and then some. Of course, some finds that doing this results in a quite startling mix of Tech Levels for any but the simplest battlesuit (quick note: GURPS Mecha defines a "battlesuit" as powered armour where the pilot's arms and legs extend into the suit's arms and legs. A "mecha" is piloted from a cockpit. So the Iron Man armour is a battlesuit, while an AT-AT is a mecha).
 * The Pyramid Magazine adventure for GURPS Discworld "A Little Job For The Patrician" features a Discworld Mecha. Based (of course) on a design by Leonard of Quirm, adapted by a brilliant Agatean nobleman whose narrative causality tends towards anime tropes, and powered by five trolls. The trolls even go through an Invocation as the thing assembles ("Other leg troll, put it together!"), although since they're trolls in a warm climate, it's possible they'd forget which one went where otherwise.
 * The mix of Tech Levels makes sense. Steel (TL 3) is still quite common as a building material today (TL 8).
 * Mekton is a tabletop RPG that is meant to run just about any humongous mecha. Admittedly, there is no size scale for something on par with the Tengen Toppa Gurren Lagann, bust still...
 * Ahem. Excessive scale. Page 113.
 * The scaling system in Mekton Plus is used to build five main scales of vehicle (of pretty much any kind): 1/10 (human), 1/5 (roadstriker - motorbikes and cars), 1/1 (Imperial Guard tanks, Gurren Lagann, most Transformers), 10/1 (really big combiners, mecha that turn into buildings for concealment, Dai-Gurren, Imperial Titans, the Millennium Falcon), and 100/1 (the Space Battleship Yamato, the Transformer Metroplex, Arc Gurren-Lagann). There are rules to expand this scaling system to take care of "mecha bloat", so you might use a 1000/1 or 10000/1 scale to build a moon-sized structure like the Cathedral Terra or Unicron, or a 1/100 scale to build Rock 'Em Sock 'Em Robots. Excessive Scale is reserved for the really, really unbelievably big things...as written, it would be used for Unicron and up, but for a TTGL-style game, it's probably best to reserve it for light-year scaling. And, of course, you can invest in huge amounts of Expanding Plasma to turn your Optimus Prime figure into a galaxy-sized war engine.
 * The Mutants and Masterminds supplement Mecha & Manga has a chapter devoted to creating your own Humongous Mecha.
 * The satirical game Macho Women With Guns had an enemy called BattleWarMechBots.
 * The Iron Kingdoms game WARMACHINE is overflowing with mecha.
 * The G.U.A.R.D. in Monsterpocalypse use these.
 * Dust combines this with Stupid Jetpack Hitler and Ghostapo. Nazis find a Cool Ship while drilling for oil and adapt the tech into mechs, flying wing planes, bio-engineered cyborg gorillas, and zombies.
 * In Magic: The Gathering, during the Invasion block storyline, Urza created mecha to fight the Phyrexian invasion. They can be seen on such cards as Urza's Rage and Pledge of Loyalty and despite the name are represented on the card Power Armor.
 * Un related are Darksteel Juggernaut, and Darksteel Colossus.
 * Adeptus Evangelion, obviously.

Toys

 * LEGO Exo-Force is LEGO's incredibly Animesque foray into the genre, a take on the standard tropes and themes of a Humongous Mecha series.
 * Bionicle: Mata Nui is a Super Galaxy Gurren Lagann-sized robot containing the entire "Matoran universe" within himself. It was inhabited and piloted by a "Great Spirit", also named Mata Nui, who was exiled by Makuta when he committed Grand Theft Me. Makuta apparently had plans to use this new body to conquer the universe, but they... kinda fell through.
 * During his exile on Bara Magna,

Video Games
(* Not to spoil anything but the Big Bad in Fallout: Tactics uses robots, including ones that qualify as Humongous Mecha. "Vox: And now, an audience favorite-the giant mech climactic battle!"
 * The Mechwarrior video game francise is based on the Battletech/Mechwarrior pen&paper/miniatures universe.
 * The orginal Mechwarrior game takes place at the end of the Third Succession War.
 * Mechwarrior 2, Mechwarrior 2 Ghost Bear's Legacy, and Mechwarrior 2 Mercenaries deal with the events immediately before, during and immediately after the Clan Invasion of the Inner Sphere.
 * Mechwarrior 3, MechWarrior 3 Pirate's Moon, and Mech Commander are concerned with different parts of "Operation Bulldog", the combined Inner Sphere counterattack against the Clans, targeted at the Smoke Jaguars.
 * Mechwarrior 4 Vengence, Mechwarrior 4 Black Knight, Mechwarrior 4 Merrcenaries, and Mech Commander 2 all deal with the Federated Commonwealth Civil War.
 * A new Mechwarrior game, with preview video on YouTube, returns to the Third Succession War, assuming it actually comes out.
 * Mechwarrior Living Legends, a total-conversion fan-made Game Mod for Crysis Wars. Multiplayer only.
 * The Heavy Gear video games are based on a Pen & paper game universe published by Dream Pod 9. Heavy Gear and Heavy Gear 2, published by Activision in 1997 and 1999, were developed after Activision lost the rights to the Mech Warrior series. Heavy Gear primaraly features powered armor, which called "Gears" in-universe, but it also features larger mechs, called "Striders."
 * Starsiege A game very similar to Mechwarrior.
 * The entire premise of the Artix Entertainment game Mechquest is to fight aliens while in a giant bipedal mecha.
 * A Humongous Mecha in the form of a  is used in an epic battle (Unfortunately in one of the worst puzzles in a Monkey Island game) at the end of Escape from Monkey Island. No, really.
 * But if you know what to do, you can win really easily by.
 * Xenogears and Xenosaga? Humongous Mecha for days. In some cases, there are battles against giant foes where the characters have to enter said mecha, or get stepped on.
 * Xenogears has the Super Dimensional Gear Yggdrasil IV. if the name wasn't a send up enough as it was, the fact that it transforms from battleship mode to humanoid mode makes the Macross homage even more obvious.
 * There seems to be something of an arms race near the end of the game as to which side can bring out an even bigger giant robot that, for whatever reason, they didn't bring out sooner to an extreme advantage. Eventually, we get to SDGY 4 and Fort Hurricane, each of which is the size of large cities.
 * In Xenosaga, the Erde Keiser sidequest is a send-up of the more light-hearted Mecha shows (in a game that's more dark and serious). And a send-up the G-Elements in the predecessor, Xenogears.
 * Xenoblade continues the tradition. There's an entire god who fits the trope. The setting of the game takes place on the two gods, so it constitutes for roughly half of the game's landmass.
 * The Steel Kossack from early PSX video game Krazy Ivan. As the trope description says, it approaches the line between Power Armor and this trope; the eponymous Ivan controls it by doing the actual movements himself. This one falls straight into this trope, however, as the Mecha is far larger than a human.
 * Live a Live gives us Buriki Daioh, a giant ancient Babylonian giant robot. It appears in the Near Future chapter expressly for the purpose of stomping tanks, shooting lasers at airplanes, shooting missiles at larger airplane aircraft carriers, and punching (video game edition!)
 * Super Robot Wars/Taisen and Another Century's Episode. For the most part, the series consists of crossovers from an astoundingly large number of Humongous Mecha anime, though not all in the same game, or even timeline. Most games have also included original creations, both Real and Super, such as the Elemental Lord Cybuster. The original creations then got their own crossover with each other in the Original Generation subseries.
 * Size actually is a factor in combat calculations. When units with two different sizes are fighting, the bigger mech will gain defense and attack bonuses, while the smaller mech will gain evasion and accuracy bonuses. However, some attacks, like a Wave Motion Gun, can bypass these bonuses.
 * These also feature in Spin-Off OG Saga: Endless Frontier, but there, they tend to be less "as big as a building" and more "quite a bit larger than a person."
 * The Visual Novel Demonbane feature both mundane Destroyer Robot and Magitek-based Deus Machina. While the eponymous Demonbane is 50 meters tall, the form it take in prequel novel, Gunshin Kyoshuu Demonbane ([[media:demonbane-HUGE_9947.jpg|War God Demonbane]]) is the largest mecha in fiction, so big that actually destroys the universe it was in and collides with the neighboring ones. The final form, Elder God Demonbane, while not as large, has an ability known as Athleta Aeternum which allows it to summon itselves from all infinite universes, including those from realities that shouldn't exist. Nyarlathotep gets rid of the Gunshin Kyoshuu by altering the timeline of the multiverse, removing it from existence. She still keeps losing to Elder God form in their eternal fighting.
 * Metal Gear in all its stomping, nuke-launching incarnations. There's always a rationale (a missile platform which isn't limited to normal terrain) but the series makes light of the implausability anyway. Implicitly, as REX from MGS was designed by a brilliant but eccentric otaku, and the rest of the world has been caught in a REX-pirating arms race ever since. Explicitly in the prequel MGS3 when the idea of a walking tank is openly derided.
 * The fourth game
 * In Emperor: Battle for Dune, one of House Atreides' mechs bears a suspicious resemblance to REX.
 * Also of note is Hideo Kojima's Zone of the Enders series, which plays it straighter.
 * Sengoku Basara portrays mighty samurai general Honda Tadakatsu as a Humongous Mecha, thus he got the nickname Hondam.
 * Also, giant war machines usually in the style of AT-ATs are occasionally fielded as Mini-Elite Mooks, especially if the enemy commander is Chosokabe Motochika.
 * The Giant of Babil (spelled as Babel in Final Fantasy IV Advance) of Final Fantasy IV. The entire plot of the game, wherein the Big Bad's forces steal the elemental Crystals, was all performed so they could use the Crystals' power to send the Giant from the Moon, through the Tower of Babil, and to the surface of the Earth, whereupon it would raze the entire planet. Although scale is difficult to convey with super-deformed characters, it is implied that the Giant is several thousand feet tall.
 * Easier to determine in the 3D DS remake. One of the Dwarves' tanks barely reaches to what would be the Giant's toe.
 * The various incarnations of Alexander in the Final Fantasy series seem to be built out of enormous castles which were then modified into mobile robots. The first iteration, in Final Fantasy VI, even has towers and smaller castles built on top.
 * And, also in Final Fantasy VI was the Magitek Armor
 * Final Fantasy VII had a mecha called 'Proud Clod' as a boss in the later part of the game.
 * Final Fantasy IX has the summon Ark. It's not just a summon; it's a Transformer!
 * Final Fantasy XI has one in the lore and one in assumption. While the version of Alexander that is fought as a final bossfight in the Aht Urghan expansion is only about 3 or 4 times the size of a player character, the fight itself takes place in a clockwork decorated undersea ruin that has been broken into five separate pieces but connected by teleport pads. Take a wild guess what Alexander's last incarnation was.
 * The second reference is made by one of the personality types for the player's NPC ally, who muses about how the legs, head and body of a secret weapon could be hidden under three of the larger features of three of the cities (A chapel, a giant tree and a tower).
 * Not to be outdone, Dark Cloud 2 (also known as Dark Chronicle) also has a gigantic flying fortress, Paznos. Although it was only supposed to be a mobile battle station, Max and Monica's tampering with the timestream further allowed its creators to transform it into a humanoid mecha strong enough to catch, stop, and toss an equally huge flying castle which was about to fall on top of a city.
 * Goemon Impact of Ganbare Goemon. People tend to remember him by his Image Song, which begins with a shout of "DA-DA-DASH!" (He's actually an alien that just happens to look like a robot. All righty, then...)
 * Don't forget, of course, that Impact is also an international movie star that wears roller sandals and shoots bullets out his nose. No, really. And why, you ask?
 * The One Must Fall video game series was designed as a fighting game where hundred-meter tall robots remote-controlled by people smacked the [...] out of each other for profit.
 * StarCraft II features the Thor, a mecha so humongous that for a time it had the distinction of being the only Terran unit unable to be produced from a structure (and had to be built in the field). Its ridiculous size becomes the target of numerous in-game jokes. The Protoss, meanwhile, have access to the deadly Colossus, a ground unit so tall it can actually be fired upon by Anti-Air.
 * They are all trumped by the April Fools unit known as the Terratron, a unit that consists of a bunch of Terran buildings combined into a Super Robot sized killing machine that makes the Thor look tiny. Terratron, terrorize!
 * The Warcraft series gained Humongous Mecha with the third installment, which introduced large golems. The Frozen Throne, the expansion pack for Warcraft III, introduced very large golems.
 * The Burning Crusade expansion for World of Warcraft also introduced the Fel Reaver, which is essentially a giant steampunk robot powered by demonic energy. And they are terrifying.
 * The goblin-made shredders are giant robots primarily used for chopping down trees, but are also more than capable of chopping down people.
 * In Ulduar, one mech stands out... obviously I'm talking about XT-002 Deconstructor! This is an ENOURMOUS mecha, able to tear a warrior apart in a matter of seconds. Oh, and did I mention that it has the mentality and even the voice of a little child? And that it considers you, the raiders as his toys? And when he kills someone, he says, "I guess it doesn't bend that way..."? Funny, yet somewhat creepy at the same time. There are guilds raiding XT for the first time... seeing the towering mecha and preparing for an epic battle... and wiping because as soon as the boss was aggroed, everyone started rolling on the floor laughing over his voice. "New toys? For me? Oh, I promise I won't break them this time!"
 * Also, Mimiron's final form.
 * In the final battle of Fallout 3,.
 * Quadraxis from Metroid Prime 2: Echoes. That is all.
 * The Mogenar of Bryyo from Metroid Prime 3: Corruption count as well. Yes, you even fight one.
 * The mechs in the Crusader series of video games aren't humongous, per se, but they can get bigger than any human and pack some serious firepower. Also, the end boss of No Regret wears a battle suit that appears to be about ten feet tall.
 * In Command and Conquer, GDI had plenty of mecha in Tiberian Sun, from the chaingun-toting Wolverine scout walkers, to the Titan walking tanks, to the Juggernaut walking artillery platforms, to the Mammoth Mk II, which sports railguns. C&C Tiberium Wars, on the other hand, was mostly a subversion: the Juggernaut was carried over, Nod got an Avatar walker, and the alien Scrin got a tripod straight out of The War of the Worlds, but in-game fluff material mentioned how the factions were discontinuing walker production, because commandos kept running up and disabling the things with a well-placed explosive on a leg joint. Indeed, the factions' commando units can do just that in-game, taking down an enemy walker instantly. Meanwhile, Red Alert 3 introduces the "King Oni" mecha on the Japanese side and the official website data does some Lampshade Hanging on the concept, noting that it "flies in the face of decades of conventional mechanized warfare".
 * Slightly less awesome are smaller Mecha Tengu, which are in essence Valkyries designed to look as a 50s jet fighter, Striker VX, chicken walkers that transform into helicopters(Transformers, anyone?), and Steel Ronin, Wave Motion Glaive-armed Humongous Samurai Mecha. Which somewhat resemble those from Tengen Toppa Gurren Lagann. What, Gundams suddenly became less awesome, judging from the complete lack of Gundam ripoffs?
 * Or the Nod Redeemer, an Avatar on steroids with the added ability to cause a Hate Plague.
 * There's also CABAL's Core Defender that appears in Tiberian Sun: Firestorm. It makes Mammoths Mk. II look puny, its BFGs can kill anything in 2-3 hits, and they have rate of fire like machine guns. It literally takes an army to beat it. The Kane's Wrath expansion to Command and Conquer III also has an upgraded version of the Scrin's tripod mech called the Reaper Tripod. The Scrin also have a giant 6-legged bug monster mech called the Eradicator Hexapod, though people tend to say it's the worst epic unit because its special ability is bad.
 * Metal Fatigue is an RTS built on this trope. There are non-mecha units, but even the one designed specifically against mecha is pretty much useless against decently armored models.
 * In Supreme Commander, three of the four factions get in on the act-the Aeon use the Galactic Colossus as the sci-fi equivalent of a battering ram and the Seraphim Ythotha is a relatively inexpensive multipurpose superheavy assault unit. The Cybran Monkeylord diverges from the standard Humongous Mecha type a bit, being a vaguely insectoid six-legged weapons platform, aptly nicknamed the spiderbot. They also have a crab-shaped amphibious mecha called the Megalith. And there are the ACU/SCU and Siege Assault Bots for each faction.
 * Most walkers in Supreme Commander are Humongous Mechas, with the exception of Light Assault Bots. The aforementioned Monkeylord dwarfs base structures. EVERY SINGLE ONE OF THEM.  The Galactic Colossus is at least humanoid, but an ACU is about chest-height to it.
 * It should be noted even the LIGHT 'mechs', such as the UEF Mech Marines, are the height of full grown spruce trees.
 * The community eventually worked out that 1 'unit' in the first game is about 19.5 meters. The aforemntioned Mech Marine, the smallest unit in the game, is 1 unit tall. The smallest thing in the game is bigger than your house.
 * Tech Romancer, an obscure Dreamcast fighting game featuring humongous mecha inspired by super robot and real robot anime series. Did I mention that this game is in english? It doesn't get any better than this, folks!
 * To clarify- The game's in English, but all the vocal sounds are in Japanese. Even better!
 * The Elder Scrolls III: Morrowind has Steampunk Pint-Sized Mechas scattered across the game's Dwemer ruins.
 * The Elder Scrolls II also had Numidium, from the shock of it being turned on. According to Backstory, Tiber Septim could never have built an empire without it to fight. The Elder Scrolls III followed this up with Akhulakhan, which
 * Most of the Big Bads in the Ratchet and Clank series use mechs for their final showdown with Ratchet. (About the only one who doesn't is the in "Going Commando") Semi-lampshaded by Gleeman Vox in "Deadlocked"
 * Most of the Big Bads in the Ratchet and Clank series use mechs for their final showdown with Ratchet. (About the only one who doesn't is the in "Going Commando") Semi-lampshaded by Gleeman Vox in "Deadlocked"


 * The Thugs 4 Less leader in Going Commando uses two.
 * And Giant Clank probably qualifies as one too.
 * Surprising no one's mentioned the Xbox game Steel Battalion, which required a massive controller with tons of buttons costing $200 which was supposed to resemble the cockpit controls of the Humongous Mecha.
 * Steel Battalion is pretty much a Crowning Moment of Awesome for video games. It's also pretty hard core. One of the controls is a red ejector button that flashes when you take critical damage and is covered with a lift up cover. If you don't eject in time your saved game is wiped and you have to start the game again.
 * Final Fantasy X has loads of these. At one point, it's a boss (as you attempt to leave the Calm Lands), but they basically live in the Zanarkand Ruins. Inexplicably.
 * Dr Eggman really loves these, and will usually be riding one during the non-Super final boss portion of each game.
 * And then there's the Gaia Colossus (do golems count?), which is made from temples! I couldn't [...] this one if I tried.
 * Viewtiful Joe, as an Affectionate Parody of Sentai, loves this trope. In particular, the escalating size of Joe's "Six Machine" mecha starts to look like Tengen Toppa Gurren Lagann after a while.
 * First there's Captain Blue's mecha, Six Majin. It's about as big as Voltron, and towers over city buildings.
 * At the end of the first game, Joe upgrades it to Great Six Majin, who is big enough to circle the earth in a few strides.
 * Things get truly ridiculous in the second game, where Six Majin and Great Six Majin combine to form 6x6 Majin, who is bigger than the planets (its fist is only a few times smaller than the Earth). This is itself a counter to the final boss' Black Kaiser, which is bigger.
 * Metal Wolf Chaos, though some would argue it is more of a Mini-Mecha, if not a Powered Armor.
 * You never actually fight Dist himself in Tales of the Abyss, but you do fight a series of mechs he constructs using fontech.
 * Likewise in Tales of Innocence, where Mad Scientist Osbald is working on powering Humongous Mecha using People Jars filled with Reincarnated. First you free a party member being used as the fuel cell, then you find the mass-production model on a battlefield, and finally Osbald pilots one against you himself, using as the power source.
 * Don't forget the recurring enemy Murder and his ilk, who range from dog-sized Spider Tanks to full-blown mecha that reach to the top of the screen.
 * A steam-powered mecha appears in the fourth chapter of Limbo of the Lost to save the day.
 * The first part of the final boss in Disaster: Day of Crisis turns out to be
 * Armored Core: High-speed (in the later games) combat using mecha that you build yourself from the ground up. The biggest appeal of the game is that whatever mech you use, you built it yourself. Which of course requires the mention of it's younger brother;
 * Chromehounds. Just as much, if not more customizable, with the major difference between it and the Armored Core series being about 300 MPH. Loved/hated because of it's speed, it places mecha combat in a more realistic (all things being relative) setting, keeping the focus on blowing stuff up while changing the game from "fly fast and Shoot Everything That Moves" to a more tactical game. Squads that fail to utilize the different role types and don't have an effective commander quickly find themselves scrap metal.
 * During the Neroimus War, each nation has its own "Unidentified Weapon" that acts as a superboss to help out a country on its last legs. The Sal Kari Unidentified Weapon, the Ghalib, is about 210 feet tall, but has a maximum height of around 330 feet when it opens up its heat-seeking missile silo. A large ACV squad accompanying you, seeing this silo, open fire. The Ghalib not only receives virtually no damage from their combined attacks, but then proceeds to wipe them all out with a single salvo.
 * City of Heroes has the Titans used by the Malta Group- the Kronos Class Titan is the size of a building. But, that's nothing compared to
 * There are
 * Also,
 * Power Dolls, unusual in that authors both Justified it (colonists weaponized a line of power loaders to defend themselves) and considered tactical problems: first, there is beyond-visual-range action, but stealth "shields" shorten the detection range, big target or not; second, PLD got lesser Endurance than a main battle tank (60 X3A/75 X3AC vs 70 M43T/90 M58T) and thus have to use good tactics relying on artillery support, stealth and slightly better sensors.
 * In Road Runner's Death Valley Rally, the Final Boss is the "Solid Tin Coyote" from the episode of the same name. Real Nightmare Fuel.
 * The Ray Series has Humongous Mecha... in ship-based Shoot Em Ups.
 * In Universe At War: Earth Assault, the Novus heroes Mirabel (a Human Alien with a tatoo on her head) and Victor (Her powered armor with an AI package) tower over the human sized Ohm Robots and Masari, and let her go toe-to-toe with Heirarchy hero Orlok and Grunt troopers.
 * There's the Hierarchy's War of the Worlds-inspired walker units, which also serve as their production structures. They are heavily armed with guns that fire plasma projectiles the size of small cars for standard weapons, and be customized with more guns like those, anti-air guns, heavier, bigger guns, and the ability to bring in different units. They are the apex of the Mighty Glacier, they are so big that they can crush most anything, including structures, but they are the slowest units in the game. The Hierarchy's units as a whole as the slowest, but their walkers move at a snail's pace even compared to them.
 * In the Civilization IV mod Next War, you are able to build Juggernauts, the second most powerful unit (behind Dreadnoughts) in terms of raw Strength, which are basically walking tanks. The Civilopedia lampshades how impractical mechs are compared to regular tanks, but notes that the world's militaries poured tons of money into them because they're just too cool.
 * The Mod Fall From Heaven has the Mithril Golem, which is a unique Unit that can only be build in the Runes of Kilmorph Holy City and requirea (besides Mithril) you to have Runes of Kilmorph as state religion and the Armageddon Counter is at least 70. It is very much larger then any unit except some other similarly powerful units like one of the four Dragons, the Meshabber of Dis, the Avatar of Wrath and Auric Ascended.
 * Civ V has Giant Death Robots if you reach the Future Era.
 * The Jak and Daxter games have several: one serves as the final boss in the first, and the third has two: one that wraps up the first act, and one that is as big as a freakin' city serves as the final boss.
 * Megaleg in Super Mario Galaxy is a giant three legged Snifit-shaped robot that fires Bullet Bills, and is literally bigger than the moon it's standing on. There's also Mecha Bowser in this game and Super Mario Sunshine.
 * Although not in terms of design, there was King Boo's Bowser mech in Luigis Mansion, although very intricately designed and powered on magitech. Could be one of those fake Bowsers from the original Super Mario Bros.. for the NES though.
 * Similarly, in Mario & Luigi: Bowser's Inside Story, you've got the Giant Bowser bosses the Tower of Yikk and Super Peach Castle (the robotised Princess Peach's Castle).
 * In the second game, there's a giant humanoid robot called Megahammer (according to Mario Wiki) with multiple Bullet Bill/rocket launchers fought as a boss, as well as a smaller version of Megaleg (Digga-Leg) to be defeated using the drill powerup.
 * In No More Heroes 2: Desperate Struggle, you go up against a football player and his horde of assassin cheerleaders who pilot one of these... with your own Humongous Mecha, Glastonbury (from a Show Within a Show). After the fight it gets confiscated, though.
 * In Mass Effect, among other bad boys, you fight a "non organic" species called Geth,  that range from small sentry turrets, to Humongous spider like mechas that are almost imposible to kill without a tank.
 * in Mass Effect 2.
 * Mass Effect 3 has Reaper Destroyers, small Reapers used for ground assault. Yep, "small". This is how big they are.
 * In Mass Effect 3, Cerberus soldiers sometimes use large Atlas mechs, which are outfitted with rocket launchers, a scaled-up shotgun, and can one-hit-kill anyone in melee range. If your aim is sharp enough, you can kill the pilot without destroying the mech, then commandeer the mech for yourself.
 * Evil Twin Cypriens Chronicles has the Sea Sewers, robots so huge that they are able to cross the sea by walking over the sea bottom. They are tasked with decimating every last trace of the old world.
 * Hope from Final Fantasy XIII seems to be a Mecha fanboy. He twice shows a knack for commandeering Pulsian Dreadnoughts. The first time he rides one he has it wade through a sea of enemies, utterly curbstomping them. The second time he takes command of one, it summons a dozen other Dreadnoughts to save Hope from being crushed by the Fal'Cie Atomos and tame it in the process. Yeah, that's right; Hope activated a Giant Robot that then brought in a dozen more Giant Robots to pull a Big Damn Heroes moment by punching out and taming a robot god. It should come as no surprise that Hope's Eidolon is this game's incarnation of Alexander -- one that can transform into a huge fortress armed with divine lasers.
 * This is one of the monster types available in Crush Crumble and Chomp, most notably Mechismo.
 * Towards the end of Enslaved: Odyssey to the West, you and your allies capture the Leviathan, a truly humongous mecha, which dwarfs all other humongous mechs in the game.
 * Kingdom of Loathings MagiMechTech MechaMech: "It fires a torpedo at you. A pink torpedo. KAWAIII!! I mean, OW!". It's more of a Mini-Mecha, but even more Fun Size versions are the MagiMechTech MicroMechaMech (say that three times fast) and MagiMechTech NanoMechaMech.
 * Okami's final boss, Yami, the lord of darkness, is a small fish-shaped thing. He pilots a spherical mech, capable of numerous different forms and attacks, including one that extinguishes all light in the area.
 * Okamiden has the Daidarabotchi, a superweapon from the moon tribe shaped like a giant rabbit that is capable of destroying Nippon. Unfortunately, we never see it move.
 * The golems in Wild Arms.
 * Sanae and Cirno's respective story lines in Unthinkable Natural Law (12.3) involve them chasing after a huge human-shaped shadow, which Sanae believes to be a giant robot. Subverted at the end of Sanae's story though, when you find out that
 * Vanquish is crawling with these.
 * Two of the eponymous monsters in War of the Monsters, Ultra V and Robo-47.
 * Musha Aleste and Robo Aleste are mecha-based Shoot Em Ups.
 * Raidou Kuzunoha vs. the Soulless Army has the Soulless Gods Oumagatsu and Yasoumagatsu, Taisho-era dreadnoughts retrofitted into towering, bipedal monstrosities which still happen to be very heavily armored and loaded with enough cannons to level cities and thermic rays. The main flaw of the model? It requires absurd amounts of spiritual energy to work, and once cut off them, the organic parts just melt.
 * Not a mecha so much as being a cyborg, but Asura

 * Web Comic subversion: In Mechagical Girl Lisa A.N.T., the A.N.T is a Humongous Mecha... for ants. To a human, it looks more like a Powered Armor.
 * In Megatokyo, the police cataclysm division (which facilitates cataclysms like 'zilla, zombie, and alien attacks, as long as they are done in an orderly fashion) employs mecha. They turn out to be less effective than robot-girl Ping.
 * In this Loserz strip. Just for fun, in this case.
 * Sluggy Freelance parodies this a few times, most notably in the GOFOTRON arc.
 * Torg thinks their machines transform into humanoid mode at all because they'd rather have each unit Walk the Plank on a glorified space barge than build proper catapults.
 * Girl Genius has plenty of them, given that Sparks love to build stuff like that.
 * The first time that Agatha is without her Restraining Bolt, she builds one out of spare engines and parts in her sleep. It leads Baron Wulfenbach straight to her door.
 * An even better example might be the Duke D'Omas' Walking Gunboats. Which are, well, Exactly What It Says on the Tin. It should be noted that the Duke D'Omas was "mad as a bag of clams ," though the gunboats do look most impressive.
 * Medical Mecha
 * Molly's robot lion from The Inexplicable Adventures of Bob.
 * Chicanery has the might of The 2000" TV's Frank.

 * Titanzer, the main character's robot and title of the webcomic.
 * Stubble Trouble once showed a giant robot tearing up the city while fighting several superheroes. Guests from another webcomic (in a crossover appearance) wondered why nothing this cool ever happened in their town.
 * Kiwi Blitz has these for war and sport, though none of them so far were humanoid - the protagonist drives, well, a fancy kiwi bird built for stunts, and the only true military model shown was an "arachbot" - 8-legged armored box with cloaking device and a few missile bays and gun/missile pods.

Web Original

 * The Impossible Man dedicated an entire chapter to a giant robot called, The Clipperstein Mark 100 Version Beta II X Turbo.
 * The prototype in The First Run.
 * Neutro from Atop the Fourth Wall.
 * Ilivais X is basically a mecha anime in Web Serial Novel format, using both Real Robot and Super Robot influences. The eponymous mech (and the others like it) are more streamlined and shiny and just futuristic in general than other examples present.
 * 'Tiny Tim' in the Whateley Universe, which the inventors are still working on, since - in keeping with real physics - it is so big it can't take a real step.

Western Animation

 * Transformers and the various series showcase a Western version of the archetypical transforming mecha. It's especially notable because unlike the usual mecha show, there are no pilots or crew to be the stars - the mecha themselves are the stars, being sentient robots.
 * It has been speculated that the on-and-off popularity of Transformers in Japan is because it lacks pilots or other very important human characters... usually. When annoying kids are put in, the American fanbase, which is much larger and more consistent, shudders.
 * The Japanese versions of Transformers appear to support the theory that giant transforming robots without pilots are alien concepts in Japan. While the Western series give reasons for their alternate modes (disguise, protection from radiation, etc.), the Japanese series, such as Transformers Armada, generally disregard them-although, as the series exist to advertise toys, they transform anyway. This reached ridiculous heights in Transformers Energon, where the Transformers, capable of flying around in space in robot mode, transform and drive in space.
 * Something else to be noted is that, even in a show of humongous mechas, some of them were EXTREMELY humongous. There was Sky Lynx and Omega Supreme, who were overshadowed by the fortress-bots Metroplex and Trypticon, who were in turn dinky compared to the city-bots Fortress Maximus and Scorponok. To say nothing of the Chaos Bringer, Unicron, or the Transformers' creator god, Primus, who are freaking planet-sized Transformers.
 * Voltron was, for a time, the best-known example in America. It was a Macekre of two fairly obscure shows, GoLion (Lion Voltron) and Dairugger XV (Vehicle Voltron), along with some Lion Voltron episodes produced by Toei especially for the American market.
 * Cartoon Network's Megas XLR is possibly the best Western parody, with an alien robot from the future crash-landing in a New Jersey junkyard, where the main character, Coop, buys it for two bucks... which he never actually pays.
 * Parodied occasionally in Dexter's Laboratory and The Powerpuff Girls.
 * Parodied in Total Drama Island, where Duncan, while trying to catch a raccoon, faces a horde of raccoons forming a huge machine-like army by standing on top of one another. Duncan comments that it's "more than meets the eye!"
 * Parodied again during Action. Harold and Beth have to fight in ones during the Kung Fu challenge, but they turn out to be very simple, giant versions of Rock 'em Sock 'em Robots with Duncan and Courtney controlling them.
 * As another American example, Codename: Kids Next Door had too many mecha count, probably because its creator is an anime fan. These are normally possessed by their enemies, especially the Delightful Children from Down the Lane, who have a seemingly inexhaustible supply. However, Numbuh Three (who is, incidentally, of Japanese descent) has her own mecha, Hippy Hop (A robot bunny). Then again, Hippy Hop never seems to get the chance to do anything each time it's deployed.
 * In one episode of South Park Chef's giant plasma TV transforms into a humongous mecha at the end and goes on the rampage.
 * In another episode of South Park, Barbra Streisand transforms into a humongous mecha and goes on the rampage. However, it's not a not humanoid but a godzilla-like machine. The word 'mecha' is used in the episode to describe Ike, who's merely giant and not mechanical in any way.
 * And who could forget when Brian Boitano traveled through time to the year 3010, fought the evil robot king and saved the human race again?

 * Leave us not forget Mighty Orbots.
 * Insektors had Koa the Frog/Operation Frogbucket, which resulted in an army of giant mechanical frogs.
 * Aladdin: the Series: Clock Punk inventor Mechanikles must have read this entry, because most of his giant mecha are based on arthropods. One exception was a Humongous Mecha shaped like himself, but he soon lost it to a boy who fell into the cockpit.
 * Kim Possible has plenty of giant mechas. Examples the robot from the pilot, the robots from The Movie, the robots from the Grand Finale and a big flamingo.
 * Parodied in Pinky and The Brain: Brain and his archnemesis Snowball the hamster are battling in their robotic human disguises when suddenly Snowball's suit transforms into a Humongous Mecha, complete with rockets blasting out of its shoulders...
 * In an homage to Lex Luthor's Powered Armor, resident Rich Bitch Alexis apparently built her own (relatively small) mecha-suit on Legion of Super Heroes.
 * The Lizard Slayers in Godzilla: The Series.
 * Super Robot Monkey Team Hyperforce Go! is about a kid and a bunch of robot monkeys who live in a Mecha.
 * Parodied in The Venture Brothers. Season 1's "The Trial of the Monarch" features Hank & Dean's fanciful retelling of a battle with the Monarch in which they become "Mecha-Shiva". Season 3's "The Lepidopterists", Jonas Jr.'s team form a Voltron like mecha to take on the Monarch.
 * Rugrats in Paris: The Movie features a Humongous Mecha Reptar.

Other

 * Code Guardian, set during WW 2, has a giant German mecha duke it out with a giant American mecha as the former tries to destroy a naval ship yard only to have.
 * Kotobukiya's Frame Arms. The background story provide that the Frame Architect was originally suppose to be labor machine in grand scheme known as Project Re Sphere. After 10 years of trial and error, they finally get Frame Architect 001 which can mimic human movement perfectly and can use in all environment by swapping parts. Unfortunely, Project Re Sphere doesn't get launch and Frame Architect instead got turn into weapon known as Frame Arms by various nations.

Real Life

 * Some kind of weaponized excavator would come pretty close to a more feasible version of the same concept, as demonstrated on one double-length Scrapheap Challenge special (albeit with smaller excavators then you'd need to really be this trope). Summary here.
 * A company called Boston Dynamics developed a four-legged Mini-Mecha capable of carrying 88 pounds and withstanding significant force without falling over.
 * Though not a military vehicle, the civilian-made, six-legged Timberjack Walking Machine probably deserves a mention.
 * Carlos Owens, a former army mechanic, spent four years and $25,000 to build an 18-foot tall steel mecha. No, really.
 * California-based Mechanized Propulsion Systems is working on designing and building a humanoid bipedal mecha within the next 25 years.
