History HumongousMecha / AnimeAndManga

* ''Literature/AsuraCryin'' has the Asura Machina, which is at least mecha-like.

* ''Literature/FullMetalPanic'', like ''Gasaraki'', attempts to show "realistic" robots in a "modern" setting, but is considerably more relaxed about what constitutes "realistic", and much lighter-hearted. It also acknowledges that man-shaped robotic fighting machines are at the very least unlikely, but promptly [[HandWave handwaves]] the objection away with a mysterious source of ultra-advanced technology.\\\
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.

* The eponymous Objects from ''Literature/HeavyObject'' are armored fighting machines which possess vastly superior offensive and defensive capabilities, and outclass normal armies and weapons with their ability to decimate an entire base in a short period. Unlike most examples, they do not have a humanoid form.

* The main villains in ''Literature/ScrappedPrincess'' are capable of transforming into Humongous Mecha. They are forced to use {{power limiter}}s to maintain a normal human guise until they are authorized to carry out their mission.

* The Guardian robot in ''Literature/AWindNamedAmnesia''. Originally created to enforce law and order in Los Angeles, it continued to function long after the pilot died and now hunts down and kills any humans it finds. It becomes a SuperPersistentPredator to Wataru after he shoots it the first time.

* ''Anime/TengenToppaGurrenLagann'' takes the "humongous" part to ridiculous extremes, with each incarnation of the main mecha being [[MetaMecha piloted by the smaller mecha]]. The show starts with the MiniMecha, Lagann, which was discovered by [[TheHero Simon]]. After [[HotBlooded Kamina]] hijacks an enemy mecha, which he names Gurren, he [[CombiningMecha 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 TimeSkip, Team Dai-Gurren acquires the Arc Gurren Lagann, which is about the size of a city. Then [[ThatsNoMoon the moon turns out to be]] a huge [[TheBattlestar starship]] which [[TransformingMecha is transformed]] into the appropriately moon-sized Super Galaxy Gurren-Lagann. Finally, in the FinalBattle, [[spoiler:Simon and the Team Dai-Gurren combine their [[EvolutionaryLevels Spiral Power]] to manifest [[TitleDrop the Tengen Toppa Gurren Lagann]], which is [[WordOfGod confirmed to be]] ten million light years in height.]] The second movie, ''Lagann-hen'', does takes it to the next level, but [[spoiler: the Super Tengen Toppa Gurren Lagann is more of an EnergyBeing -- a humanoid figure made out of Spiral Energy flames, with Kamina's cape and Simon's CoolShades which are actually the Tengen Toppa Gurren Lagann floating ''in the middle of the Super TTGL's face''.]] In other words, if you like humongous mecha, this is porn for you.
* ''Tetsujin #28'', or ''Anime/{{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.

* ''Anime/SpaceRunawayIdeon'' features unusually large mecha for its time, with the Ideon being 105 meters tall. While the most numerous {{Mooks}}, Adigo, are 48 meters tall when standing straight, and considered as ''small'' class mecha, most of the {{Elite Mook}}s are taller than Ideon.

* ''Anime/{{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.
** The "incomprehensible mass of mysticism" also gave the series the Kugai, ancient Japanese proto-mecha in the form of giant suits of samurai armour, brought to life by ritualistic Noh dancing, with the dancer sitting inside the suit's abdomen once the Kugai was activated and controlling it by their will. The one time a Kugai is activated in the story's present, it attacks a Tactical Armor and rips it apart with its bare hands, and in the ancient period in which they were created they (unsurprisingly) made the clan who owned them almost invincible in battle.

* ''Manga/OnePiece'':
** Vegaforce-01 is a giant mecha built by [[WorldsSmartestMan Vegapunk]] and piloted by Lilith, measuring around 300 meters in height and strong enough to carry the Going Merry in one hand. [[spoiler:It is modeled after the Iron Giant, a 900 year old ''autonomous'' mecha the size of a city slumbering in Egghead's scrapyard.]]

* ''Manga/AttackOnTitan'': No really. [[spoiler:The Shifters' Titan forms]] are a flesh-and-bone version of this, with some fight scenes sceaming ''Anime/NeonGenesisEvangelion''.

* ''Anime/BubukiBuranki'' has the [[CombiningMecha Buranki]], which are controlled from the ''outside'' by their component [[EmpathicWeapon Bubuki]]'s users, each perched on the top of the part of the Buranki which they wield individually.

** [[Recap/NeonGenesisEvangelionEpisode07AHumanWork Episode 7]] features Jet Alone, a more conventional mecha that is purely mechanic and powered by a nuclear reactor. It was a private attempt at a replacement for the Evangelions that fails [[spoiler:partially because of NERV's sabotage]].

* ''Anime/NeonGenesisEvangelion'': The titular Evas are [[MeatSackRobot biological robots]] in the form of [[spoiler:cloned EldritchAbomination]] humanoid beings plated in restraining armor and having their spine and nervous system fitted with cockpit housing units. This is important because the Entry Plugs, designed to mentally and physically synchronize the pilot with the Eva in conjuction with LCL, will vary in effectiveness depending on their depth and the pilot's psyche, [[spoiler:to the point that going too far can and will result in the synchronization transcending metaphysical levels]].
** Jet Alone is this trope played straight.

** The "incomprehensible mass of mysticism" also gave the series the Kugai, ancient Japanese proto-mecha in the form of giant suits of samurai armour, brought to life by ritualistic Noh dancing, with the dancer sitting inside the suit's abdomen once the Kugai was activated and controlling it by their will. The one time a Kugai is activated in the story's present, it attacks a Tactical Armor and slices its arm off with a giant katana, and in the ancient period in which they were created they (unsurprisingly) made the clan who owned them almost invincible in battle.

* ''LightNovel/AsuraCryin'' has the Asura Machina, which is at least mecha-like.

* ''LightNovel/FullMetalPanic'', like ''Gasaraki'', attempts to show "realistic" robots in a "modern" setting, but is considerably more relaxed about what constitutes "realistic", and much lighter-hearted. It also acknowledges that man-shaped robotic fighting machines are at the very least unlikely, but promptly [[HandWave handwaves]] the objection away with a mysterious source of ultra-advanced technology.\\\

Unlike most examples, they do not have a humanoid form.

* ''Anime/{{Patlabor}}'' focus on MundaneUtility of Humongous Mecha anime tropes, featuring short, non-combat robots used for civilian purposes such as construction. The combat robots belong to the police, who prevent mecha-related crimes, the military like the Japanese Self-Defense Force, and MegaCorp like the Schaft Enterprises.

* The main villains in ''LightNovel/ScrappedPrincess'' are capable of transforming into Humongous Mecha. They are forced to use {{power limiter}}s to maintain a normal human guise until they are authorized to carry out their mission.

* ''Anime/CrossAnge'': The [[AntiMagic Normas]] who are shipped to Arzenal to become a part of the ArmyOfThievesAndWhores there are trained to pilot Paramails, [[TransformingMecha mecha that can shift between a fighter mode and robot mode]]. With the Paramail, the pilots of Arzenal fight the vicious interdimensional [[OurDragonsAreDifferent DRAGON]] invaders that portal into the main world. [[FallenPrincess Ange]], the main character, uses a more ancient model called Villkiss, which is a much older ''Ragnamail.'' [[spoiler:The Ragnamail are an invention of the BigBad, [[AGodAmI Embryo]], who pilots his own Ragnamail named Hysterica (which is also an extension of himself). He also provides several other black Ragnamail to his Diamond Rose Knights, which vaguely resemble Villkiss aside from color.]]

[[FallenPrincess Ange]], the main character, uses a more ancient model called Villkiss, which is a much older ''Ragnamail.'' With the Paramail (and sole Ragnamail), the pilots of Arzenal fight the vicious interdimensional [[OurDragonsAreDifferent DRAGON]] invaders that portal into the main world.

* In ''Manga/FairyTail'', [[spoiler:King Faust owns one called Doroma Animu, a mecha dragon]].

*** The Galahad unit used by the Knight of One is 9.5 meters tall and so heavy its sword sheath needs its own rocket booster. Tt also wields a BFS, Excalibur, about as large as itself.
