->''"Constructicons! UNITE!"''
-->-- '''Scrapper''', ''WesternAnimation/TransformersTheMovie''

When two or more independent {{mecha}}[[note]]Or other vehicles, but mecha are most common[[/note]] can combine to make another, larger mecha. It can be a decent way to hide a [[HumongousMecha really big robot]] in plain sight, by breaking it up into pieces.

After the merge (accompanied by the stock TransformationSequence), the new mecha will have powers and abilities greater than the sum of its parts. CombiningMecha are frequently a metaphor for TeamSpirit and/or ThePowerOfFriendship because of this.

It's common to find these in the same places as TransformingMecha -- indeed there are many that can do both. A frequent source of TechnologyPorn.

Who controls the combined form, and where the crew ends up after the merge, also varies. In some settings (such as ''{{Voltron}}'') the crew remains in their separate individual cockpits (with the leader responsible for most of the robot's control), while other settings like ''Franchise/SuperSentai'' and ''Franchise/PowerRangers'' transfer the heroes to a central "bridge" area in the core of the mecha and they control the robot as a group (again, usually under the leader's direction).

In most cases each mecha comprises one specific piece of the resulting robot, with the group's leader (i.e. TheHero) [[LeaderFormsTheHead forming the robot's head or torso]] in the process -- after all, the leader ''is'' the 'head' of the group, so why ''not'' have them [[WhatDoYouMeanItsNotDidactic become the literal head of the combined form]]? This also eliminates the requirement for more than one TransformationSequence, since the component mecha will always form the same result in the same manner. On the other hand, some mecha can mix-and-match their configurations to form any part of the combined robot, and it doesn't necessarily matter who forms which piece.

In many series, if a team of mecha is revealed to have a combined form, expect to see the individual mecha's abilities reduced to SoLastSeason status, with the mecha rarely used for anything ''other'' than their ability to combine. This is certainly the case with, for example, most ''Franchise/SuperSentai'' and ''Franchise/PowerRangers'' series, where once the team's Megazord is revealed (usually within the first couple of episodes, sometimes inside of the PilotEpisode), they will never use anything less. (Probably because hiring PeopleInRubberSuits to fight the MonsterOfTheWeek is a lot less expensive than the StopMotion or CGI required to animate individual mecha doing the same.)

In cases where the mecha are sapient beings with no outside pilot (such as ''Franchise/{{Transformers}}''), the resulting personality of their combined form is frequently some manner of collective consciousness formed by the component members -- this merged mind is often the result of whatever its component members can actually agree on, usually resulting in little more than a mechanized DumbMuscle whose vocabulary [[HulkSpeak consists primarily of one-syllable words]] and who can only focus on one task at a time: For the good guys, this creates a GentleGiant; For the bad guys, this simply results in breaking and smashing stuff. Lots of stuff. And killing people, don't forget the killing.

In any case, it's often unclear where the necessary parts to operate this new robot came from -- all the physical implausibilties of TransformingMecha apply, to a greater degree.

More often than not, the legs-and-feet component of a combining robot is not as cleverly disguised as the other parts. It may appear as a giant, rectangular machine with obvious foot-shaped parts protruding from behind. In contrast, the head of the combining robot is almost always hidden in some sort of recess; in the TransformationSequence, it usually emerges from said recess as a final step.

If the vehicle is a single thing to begin with but breaks apart to fight, you could be looking at DetachmentCombat.

See TotemPoleTrench and TheWormThatWalks for similar tropes involving living things.

Not to be confused with MergingMachine.

!!Examples:

[[foldercontrol]]

[[folder:All of the following]]
* ''Franchise/SuperSentai'', and therefore ''Franchise/PowerRangers'', of course. 35 years of the former and 20 years of the latter with 2-3 super robots per season mean everything's been covered. ''Everything.'' For the purpose of simplicity, ''Power Rangers'' terms will primarily be used here - ''Super Sentai'' has few cross-series terms like 'zord,' without which this becomes a lot harder to describe.
** To expand, the first Sentai, ''Series/HimitsuSentaiGoranger'', and its successor, ''Series/JAKQDengekitai'', never had mechas. It was on the third Sentai, ''Series/BattleFeverJ'', that the series had a mecha (an idea taken from the Japanese tokusatsu SpiderMan), and even that mecha wasn't a combining mecha. It was only until ''[[Series/TaiyouSentaiSunVulcan Sun Vulcan]]'' did they introduced the combining mecha idea. And even then, it was usually two or three machines combining - the ''eleventh'' series, ''Series/HikariSentaiMaskman,'' was the first to give each member a personal robot that shared his or her theme. "Great Five" was so named because it was the first robot to actually be made from five components.
** The most common system is: each of the five Rangers has a Zord corresponding to whatever the series' general "theme" is. They combine into a humanoid Megazord, which handles the fighting for the early parts of the season when the villain decides to MakeMyMonsterGrow. Then SixthRanger comes with his MechaExpansionPack which doubles the power of the ensemble. However, the variety of Zords mean there's no combining scheme we haven't seen.
** Group of vehicles to giant robot? Pick a series, any series, with a vehicle theme, or the ''Super Sentai'' that predate the Zord-per-Ranger rule (the 2-3 Zords were usually a giant plane-thing and 1-2 giant ground vehicles.)
** Group of humanoid robots to giant robot? This is perhaps the least-seen scheme, but it happens. The Shogun Zords/Ginat Beast Generals were all humanoid and formed the Shogun Megazord/Muteki Daishogun, and the Turbo Rescuezords/Victory Rescue Vehicles were like Franchise/{{Transformers}} (vehicle-to-humanoid transformation) as well as being able to make Rescue Megazord/VRV Robo. [[Series/PowerRangersZeo Super Zeo Megazord]]/[[Series/ChourikiSentaiOhranger OhBlocker]] and [[Series/PowerRangersMysticForce Titan Megazord]]/[[Series/MahouSentaiMagiranger MagiKing]] even managed to have completely symmetrical formations rather than the Voltron-style one-on-each-side. You may choose to count the times Megazords combine into bigger Megazords, but it's rare for it to ''truly'' work that way (instead, the two Megazords' component Zords can recombine and make a larger formation.)
** Group of animal robots to giant robot? Pick a series, any series, with an ''animal'' theme.
** Group of vehicles to bigger vehicle? Rare, but a ''few'' Megazords have a vehicle mode as well as a robot mode. If the components are themselves vehicles, you get five Time Jets becoming the Time Force Megazord Jet Mode, or Operation Overdrive's Battle Fleet Carrier (whose components only exist in StockFootage, sadly.)
** Mix and Match? Time Force again. There's the speedy Mode Blue, the strong Mode Red, and the too-expensive-to-CGI-often Jet Mode, all with the same components. Also, Mystic Force has a dragon formation and a Megazord formation. The first two Megazords also had a tank mode and a robot mode.
** MechaExpansionPack? More and more recent series have "auxiliary Zords" that can replace limbs to add new powers. Every year starting around 2000, both shows tend to feature a wide range of individual animals or vehicles who would start doing this with the base combined mecha. At times like this, instead of "'''''GATTAI!'''''" (combination), get used to "'''''BUSOU!'''''" (armament.) Once they acquire enough of these, they usually end up combining together to form a second complete mecha such as [=DaiTenkuu=] in ''Series/SamuraiSentaiShinkenger''/the Samurai Battlewing in ''Series/PowerRangersSamurai''; or the Dual Drive Megazord of ''Series/PowerRangersOperationOverdrive'' (presented as a 'quick and dirty' emergency combination of the spare vehicles once too many of the usual vehicles had been damaged). Sometimes they ''all'' pile onto the main mecha at once. Also, some SixthRanger mecha do this with the combined robot of the other Rangers.
*** Parodied in ''Series/SamuraiSentaiShinkenger''/''Series/PowerRangersSamurai'' when the Origami, in their emblem forms, attempt to "combine" by stacking one on top of the other. The formation isn't very effective.
** A rarer variant of this occurs when the Red Ranger's Zord can change into a humanoid robot, which then forms the Megazord by "wearing" the rest of the team's Zords as armor. So far there are only two examples: ''Series/GoseiSentaiDairanger''[='s=] Dairenoh (AKA the [[Series/MightyMorphinPowerRangers Thunder Megazord]]) and ''Series/TokumeiSentaiGoBusters''[='s=] Go-Buster[=Oh=].
* ''Franchise/{{Transformers}}'' has had combination in just about every permutation imaginable over the years; see examples in the individual folders below.

[[foldercontrol]]

[[folder: Anime and Manga ]]

* The ''Manga/GetterRobo'' series, which is the TropeMaker for the combining giant robot, though there had been combining robots as early as Manga/AstroBoy.
* [=GaoFighGar=] in ''{{GaoGaiGar}}'', which was identical to the original, but with a transforming hovercraft instead of the robot lion. (See animals-to-humanoid.)
* ''Anime/SpaceRunawayIdeon''
* ''Anime/CombattlerV'' and ''Anime/VoltesV'' (similar designs, from the same anime director). Combattler was the first such mecha to have a combination sequence that could actually be visibly followed (and as Bandai had become a sponsor, not coincidentally [[MerchandiseDriven reproduced in toy form]]).
* ''Anime/{{Zambot3}}'': Zambot was formed by the combination of three vehicles: an aircraft, a tank and a terrestrial support vehicle.
* ''DairuggerXV'' (known in America as the ''Vehicle {{Voltron}}'' series).
* ''GenesisOfAquarion'' has three fighter planes called Vectors combine into one huge robot with special abilities depending on which Vector forms the head. One forms the head, torso and arms, one forms the pelvis, legs and feet, and one forms a set of wings that attches where the abdomen would be.
* Tidal Wave in ''Anime/TransformersArmada'', who is composed of three ships called the Dark Fleet, that can also form a larger ship, and become a Mecha Expansion Pack Augment for Megatron.
* ''Anime/TheBigO'' episode 18 "The Greatest Villain". Simon Beck uses a megadeus that combines from three smaller vehicles.
* ''{{Gunbuster}}'' is formed from 2 spaceships.
** The sequel, ''{{Diebuster}}'' has the mecha in question formed from HUNDREDS of monster-like ships.
* Xabungle from ''CombatMechaXabungle'' and later the Walker Gallier are each formed out of two vehicles.
* ''{{Dai-Guard}}'' has a realistic take on this; at first, Dai-Guard must originally be carted to the site and assembled from its component parts. It later receives an upgrade that allows the sections to move on their own and assemble the mech automatically; however, they are not equipped with weapons or anything else that does not serve simply to transport Dai-Guard, and must return to their "parts" form to assemble the machine.

[[/folder]]

[[folder: Film ]]

* Devastator from ''Film/TransformersRevengeOfTheFallen''. The individual vehicles may have had their own transformations (indeed, they were used to fill the Decepticons' ranks), but the transformation started as vehicles.
* The MOGUERA unit in ''Film/GodzillaVsSpaceGodzilla''.

[[/folder]]

[[folder: Video Games ]]

* The [[RealRobot Valhawk]] ([[TransformingMecha a plane by default]]) and [[TheBattlestar Valstork]] into the Valguard in ''VideoGame/SuperRobotWarsW''. Then, both of those plus a Valhawk-sized mecha named [[SuperRobot Arm Arcus]] and ''another'' battleship, the Arm Stora, into the [[GameBreaker ludicrously powerful]] Valzacard.
** The Elebus and Simurgh combine into the Simurgh Splendid and Earthgain and Vyrose combine into Super Earthgain in ''VideoGame/SuperRobotWars64''.
* In ''Videogame/WorldOfWarcraft'', the fight against the boss Mimiron in the Ulduar dungeon goes through four distinct phases: the first against the Leviathan Mk. II (a miniature version of the tank fought as the first boss in the instance), second against the VX-001 Anti-Personnel Cannon (a turret with two guns on the side), and the third against the Aerial Command Unit (a helicopter). The * fourth* phase consists of fighting [[ShoutOut V0-L7R-0N]], a combination of the three which looks like a giant [[MechanicalLifeforms mechagnome]].

[[folder: Western Animation ]]

* ''WesternAnimation/TheVentureBrothers'' does have one legitimate (read: not made-up) Mecha, Jonas Venture Jr.'s Ventronic, which is most definitely a Voltron parody.
** Also, During a FakeActionPrologueSimilarly, we see Hank and Dean "Form up" (or to be more accurate, one sits on the others shoulders) in order to form "Mecha-Shiva".
* Parodied in ''WesternAnimation/RobotChicken'' with a sketch where Voltron's combination sequence takes an agonizingly long time to finish (as well as the group having to start over after messing up the sequence) while the monster proceeds to destroy the space station.
** For those curious, it was the vehicle Voltron used in this sketch, which as its Japanese name (Dairugger XV) suggests, has over a dozen parts.
** Another sketch has the evil giant monster challenge Voltron to a dance battle. And it was awesome.
-->'''Commander Keith:''' We just got ''served'', team!
-->'''All:''' ''VOLTRON REPRESENT!''
* Multiple ''Franchise/{{Transformers}}'' groups do this, most famously the Constructicons, who form Devastator. Generation 1 (Original) Devastator was formerly used as the picture for this page.
** From the original G1 series alone there were the Constructicons (Devastator), Stunticons (Menasor), Combaticons (Bruticus), Predacons (Predaking), Terrorcons (Abominus), Seacons (Piranacon), [[http://en.wikipedia.org/wiki/Monster_Pretenders Monster Pretenders]] (Monstructor), Aerialbots (Superion), Protectobots (Defensor), and Technobots (Computron). And that's not even counting the Japanese-exclusive teams (Trainbots, Multiforce...) ''or'' the subsequent series. Technically, the combiner teams could be classified as either "robots into mecha" or "vehicles into mecha", but since most of them had to transform into vehicle forms before combining, "vehicles into mecha" seems more accurate.
*** Aside from Tidal Wave, mentioned above, the truest example of this form in Transformers would be the Duocons: two vehicles (one land and one air in both cases) combining into a single robot, with no robot modes for the individual vehicles. The cassette teams of Raindance (cassette/jet-fighter) and Grand Slam (cassette/tank), who combine into the robot Slamdance, and Beastbox (cassette/gorilla) and Squawktalk (cassette/parrot) who combine into the robot Squawkbox, also count.
** ''WesternAnimation/TransformersAnimated'' is a special case regarding Transformers, as there was only one combiner robot, and he was formed from only two components: the Twins Jetfire and Jetstorm, who symmetrical dock to form Safeguard.
** The movie Constructicons are a bit of a blurry case; [[spoiler:explicitly, they only ever go from vehicle to combined mode on-screen, but other 'cons in the larger battle had the same vehicle designs - and individual robot modes.]] Meanwhile, the [[MerchandiseDriven toyline]] isn't helping matters; the $100 "Supreme" Constructicon Devastator goes vehicles-to-Devastator with no individual robots, but it also has its own screen inaccuracies, like, for example, completely omitting one of the Constructicons. On the other hand, there's a set of all seven Constructicons available in the "EZ Collection" (Legends class; really small) class that can form both individual robots and a combined form. WordOfGod is that Devastator is one robot who had to be split into seven (eight?) vehicles because nothing on Earth was big enough. There are others that don't technically qualify as Constructicons; it's just that their vehicle modes are coincidentally the exact same as Devastator's separate components.
*** Don't forget the movie Arcee: in the toyline, she is composed of three motorcycles that combine into one robot. The combined form was originally going to appear in the movie, but was ultimately cut.
** [[CrowningMomentOfFunny Hilariously subverted]] in ''ComicBook/TransformersLastStandOfTheWreckers'':
--->'''[[TheAce Rotorstorm]]''': Wreckers, COMBINE!\\
''[{{beat panel}}]''\\
'''Rotorstorm''': Well, '''''I''''' thought it was funny.
*** What's really great about that moment is that there are exactly five Wreckers present--the number needed for a typical Transformers combiner.
*** And Overlord himself is a one-mech combiner, with his top half forming a jet and his bottom a tank.
*** The ''VideoGame/TransformersFallOfCybertron'' would later actually give the Wreckers a CombiningMecha form called Ruination, who was a remold of Bruticus from the same line. (Sadly, this did not include a "Fall of Cybertron" version of Rotorstorm himself.)
** Of particular note is the ''Power Core Combiners'' toyline, which features combining as its central gimmick. However, its combiners aren't what TF fans are used to; instead of five separate mechs, each combiner is composed of one mech and a number of drone vehicles that only transform for the sake of the combination.
** Transformers is another series that gives us a number of types. Vehicles/beasts to robot, check. Humanoids combine, check - though if it doesn't involve a return to vehicle mode it's usually a two-bot combiner. Vehicles into vehicle, check - again, typically applies to two (Dreadwind and Darkwing become Dreadwing, which is a jet with no robot mode. Jetfire and Jetstorm combine one way to become Safeguard's robot mode or another to become Safeguard's jet mode.) Interchangeability, check. Expansion pack... many versions of Optimus Prime can combine with one other bot to become Optimus Prime [Something] Mode, so the story treats it that way, though the combinations are involved enough you'd think it was "two become new robot" rather than "Optimus is wearing Wing Saber" to look at them. RID's Omega Prime, though, is the only Optimus combo to be treated as not exactly either of his components. Heck, there's even a few ''really'' weird ones, like three vehicles/humanoid robots combining into ''weapons for larger robots to use'' (the Star Saber, Requiem Blaster, and Skyboom Shield from ''Anime/TransformersArmada''), and a couple really off-the-wall instances of ''animals combining into a larger animal'' (Sky Lynx from G1 and Magmatron from ''Anime/BeastWarsNeo'', the latter's organic beast modes resulting in a particularly bizarre combined alternate mode.) Even some cases where two Transformers have separate robot modes, but must combine to form a vehicle. And then there's Six-Gun, made mostly from Metroplex's guns.
* [[AffectionateParody Parodied]] in ''WesternAnimation/TitanMaximum'', down to the letter. (While they have shown the animation of the transformation sequence, most times they cut away to observers commenting on how long the transformation takes.)
* Parodied in VH1 Illustrated where George W. Bush suggests building 5 giant robots that can combine to form a even bigger robot to fight (fake) nuclear monsters.
* One episode of ''Mighty Man'' featured a HumongousMecha whose pieces were disguised as Chinese Ships (called Junk).
* The ''WesternAnimation/SuperRobotMonkeyTeamHyperforceGo''! Super Robot has this one. [[{{Troperiffic}} As well as about every other Super Robot trope...]] {{Inverted}} in that the Super Robot is usually seen as one big robot, and only rarely separates.

[[folder: Anime and Manga ]]

* The Symmetrical Docking pairs in ''{{GaoGaiGar}}'', and Big Volfogg in the same series.
* The original ''Manga/AstroBoy'' manga (which predates ''Manga/GetterRobo'' by a good 20 years) had two of these. First there was Gadem, a group of 47 androids who combind to form a giant centipede (although he was later redesigned as a collection of magnetized gold particles in the remake) & one story even had Astro himself becoming part of a combiner made up of other humanoid robots in order to fight a giant snow leopard who was actually a combination of billions of electricity eating space amoebas.
* ''MagicKnightRayearth'' has a variation with its three Legendary ''Mashin'' (Rune Gods). The ''Mashin'' are {{Humongous Mecha}}s that initially have the appearance of a dragon (Seles), a phoenix (Windam) and a lion (Rayearth). When the three spirits merge, the result is again a HumongousMecha with all three Magic Knights inside.
* [[http://www.youtube.com/watch?v=AxU_NFrleDY&fmt=18 Happens all over]] ''TengenToppaGurrenLagann''.
** The eponymous Gurren-Lagann is a double subversion: when Kamina first puts it together, Leeron protests that it makes no sense to combine the mecha, and the results seems to be [[http://www.youtube.com/watch?v=2S884cwZ5mQ&list=FLcrebS8RqTIrC13jwiLWb-A&index=51&feature=plpp just one mecha with another drilled into its head]]. Then comes the TransformationSequence.
** In the second movie, Lagann-hen, [[spoiler:After Lord Genome converts the [[WaveMotionGun Infinity Big-bang Storm]] after Tengen Toppa versions of the ENTIRE Dai Gurren-dan's ganmen appear (Kittan is the only one who died before this as the {{Mauve Shirt}}s were spared in the movie. Nia also gets to use her own ganmen) they AGAIN combine to form the SUPER Tengen Toppa Gurren Lagann which resembles a body made of spiral power more than an actual mecha. Not just any body either - it's an enormous Kamina on fire with Simon's shades and the Tengen Toppa Gurren Lagann for a face.]]
** They do this all the time. The Gurren-Lagann is the combination of Gurren and Lagann. Gurren-hen has this in ClippedWingAngel form with the [[spoiler: Dai Gun Doten Kaizan, a combination of the 4 Generals Flagships. It fires one volley of missiles, then gets promptly Giga Drilled.]]
*** Lagann's special ability is that it is able to fuse with other mecha. In fact, Gurren Lagann itself is a fusion of no less than ''six'' mechs: The three Gunmen that were combined into Gurren, Lagann, A bit of the Enkidu (Viral's Gunman- specifically the helmet), and a flying Gunman.
** Lagann actually combines with several other mechs in the various incarnations of the show- for example, it fuses with what is eventually the Dai-Gurren during the Volcano battle, and in the Manga, Yoko fuses it with her own mecha.
** The combinations of mecha reach MIND-BOGGLING EXTREMES as Gurren Lagann finds new ways to transform. [[spoiler: First, the regular Gurren Lagann, combines with Arc Gurren to form the metropolis-sized Arc Gurren Lagann. Then, both machines are hooked up to a drill-powered energy plant inside the Super Galaxy Gurren Lagann to transform it into the lunar-sized mecha of the same name. And then... it goes UpToEleven times [[ReadingsAreOffTheScale Over 9000]] with the Tengen Toppa Gurren Lagann- and that behemoth '''dwarfs''' '''''GALAXIES.''''' But even ''that'' isn't the biggest mech! In the second movie adaption, the combination of the former mech and the equally-sized Space Gunmen creates the Super Tengen Toppa Gurren Lagann, a GOD-SIZED [[EnergyBeing CELESTIAL ENERGY]] MECHA NO SMALLER THAN '''''1.8% of the ENTIRE UNIVERSE.''''' With that, it is the undisputed king of this Trope! You may pick up your jaw now... Try not to have an aneurysm on the way out.]]

* ''BBSenshiSangokuden'' uses demonic possession to explain the combining of ''living'' robots: Shiba-En's summoning of Shuu Neue Ziel leads the demon to grab him, ''both his brothers'', and a robot-shaped artifact to form Senjin Gasshin Shuu Gundam.
* ''{{Bionicle}}'' sets had this as their earlier gimmick for you to buy all 6 sets, where you can combine three particular sets (although since they all shared the same template, any set could be subsituted for the "right" one you didnt have) into one giant "Kaita" model. Since they all looked like robots, it's safe to say they go for this trope. Also overlaps with FusionDance.

* In ''CityOfHeroes'', two Hercules Class Titans can combine into a Zeus Class Titan.
** And as an unfortunate beta tester memorably discovered, an allied Hercules Titan can also successfully combine with a ''player'' to form a Zeus Class Titan.

* ''VideoGame/{{Xenogears}}'', generally a SuperRobot game, featured one combining mecha with Dominia and her compatriots.
* This was later given a homage in the ''VideoGame/XenoSaga'' games with Erde Kaiser. In ''VideoGame/XenoSaga'' 1 and 2, Erde Kaiser was created from various parts which then combined into one big robot (in episode 1 the parts could actually be summoned in battle). In episode 3, Kaiser starts off already assembled.

* In ''IlivaisX'', prototypes Q through U combine to form STRUQ, which, in alphabetical order, are the head, body, legs, right cannon arm, and left blade arm. Though the individual mecha are very incompetent when in humanoid form, with the exception of [[PoweredArmor Q]].
* Parodied in Machinima/TeamServiceAnnouncement ''[[http://www.youtube.com/watch?v=xYN7RxpumU8 Fake Players]]''. Several AI controlled players, i.e. "bots", combine to form a single bot with people for legs and arms.

* Again, the ''Franchise/{{Transformers}}'' combiner teams, as listed above. Depending on the series and combination, though, the process isn't perfect, as it turns out creating a single composite mind from five or more very different robots isn't exactly easy.
** Energon has this as the main gimmick for the Autobots. Just about ''any'' two Autobots were capable of combining with one another, with one forming the upper body and the other forming the lower body. Whoever was the top half was the one in control of the combination.
* ''MightyOrbots'' is a combination of types: the components are independent robots, but their human leader and his assistant enter inside, as their craft becomes the united form's control room. Once achieved, the pair control the movements of the united form, while the robots operate their specific internal functions at the command of their leader.
* ''SymBionicTitan'' has the main characters form the title Titan by connecting their 2 sets of humanoid armor, plus the autonomous robot Octus, to form an actual humanoid robot.
* ''WesternAnimation/LegionOfSuperheroes'' has possibly the ultimate example: after his FaceHeelTurn, Brainiac 5 takes control of his entire species--composed of metamorphing robots linked in a HiveMind--and when challenged by the Legion, turns ''all of them'' into a single gigantic battlebot.

* ''Golion'' (in America, the Lion ''{{Voltron}}'').
* ''Anime/DigimonXrosWars'' has this as its core gimmick setting it apart from the preceding ''Franchise/{{Digimon}}'' series, referring to the combining process as [=DigiXrossing=]. A majority of component Digimon don't look robotic (nor do most of the resulting combinations beyond the main characters), but the combined forms of lead Digimon Shoutmon were clearly designed with classic combining mecha styles in mind.
** While not ''robots'' per se, the Advance Hybrids and Ancient Digimon for Takuya, Kouji and Kouichi from ''Anime/DigimonFrontier'' were also clearly designed in this fashion, as amalgamations of the Human and Beast Spirits they were composed of. Susanoomon (an Omegamon expy) was similarly an obvious amalgamation of Kaiser Greymon and Magna Garurumon.
* [[GaoGaiGar Genesic GaoGaiGar]]. A dolphin, shark, two moles and a bird thing were substituted for the vehicles, going the opposite way from [=GaoFighGar=].
* ''GunXSword'' has the El Dorado V. Despite being crewed by senior citizens, it easily surpasses all other examples on this list when it comes to being fueled by [[HotBlooded hot blood]].
* ''{{Dancougar}}'' probably has the most extreme version of this. Each of the robots can transform between animal, vehicle AND humanoid forms, and they can all combine into a giant robot.
* Magmatron, of the Japanese-only ''{{Transformers}}'' series ''Anime/BeastWarsNeo''. Unlike most of the examples from ''Transformers'', Magmatron was actually one individual that could separate his body into three smaller dinosaurs. The dinosaurs could also combine to form a [[MixAndMatchCritters bigger dinosaur with three heads]].

* The 15 "small" vehicles of ''DairuggerXV'' (the "other" Voltron series) could not only combine into one gigantic robot, but also combine (in three specific groups of five) into three larger vehicles.
* Each unit in the BraveSeries ''TheBraveExpressMightGaine'' had a train form. Each of the different "teams" (Might Gaine, Might Kaiser, the Bombers, and the Divers) were also capable of taking on a combined train form, which, along with Might Gunner's train form, could lock together to perform their ultimate (and sadly, only used once) FinishingMove, the Joint Dragon Fire. Given the fact that the hero of the series is a teenage train magnate, this is about as surprising as finding sand in the Sahara Desert.
* Gattiger in ''SupercarGattiger'' is formed by combining its five component cars -- the Center Machine, Left Machine, Right Machine, End Machine, and Back Machine.

* In the {{Xbox 360}} freeware title ''AegisWing'', when two or more player ships come within a certain range of each other (you can tell because a line of dots show up with a blue X in the middle), a player can press X to flip and connect to the other guy. The one who initiated the merge becomes an omnidirectional gun turret, while the mergee steers and fires the forward gun.
* Two Player Mode in ''{{Blasteroids}}'' can have one player with a ship in Speeder mode (small, fast and maneuverable with little armor or firepower in exchange) combine with the other's ship in Warrior mode (large, slow but heavily armored) to form the Starlet: The Speeder becomes a player-controlled turret that has firepower increased for its role, while the Warrior body of the Starlet loses its firepower but gains maneuverability in exchange.
* In ''Videogame/WingCommander: Prophecy'' one common enemy fighter is the skate. They are able to form a "cluster", capable of laying mines, launching torpedos, and carrying out bombing runs with a cannon that can damage capital ship components. Needless to say, it's safest to knock apart any clusters and destroy the individual ships before they can combine.
* ''VideoGame/StarForce'' has an enemy like this called Larios, which is a core that summons other fortresses to combine with it. Destroying the core before the fortresses combine with it is worth a bonus 50,000 points.
* In ''VideoGame/{{Dogyuun}}'', player 1 can fuse with player 2 to combine into a larger plane. This allows the players to get massive firepower, but it also comes with a price- if it gets hit, ''both'' players lose a life.

* A small handful of ''Franchise/{{Transformers}}'' combine into larger alt modes instead of larger robot modes. Dreadwing is probably the best example. Of course, they all had their own robot modes anyhow... save for Tidal Wave, who was a big robot, a big ship, or three small ships.
* The concept was parodied in an episode of ''{{Reboot}}'' when the characters piloting the individual animal-mechs (in this case, insects) first couldn't figure out how they were supposed to arrange themselves to form the giant robot, and then when they did, the resulting robot looked nothing at all like it had been formed from the components that made it up.
[[/folder]]

[[folder:Mix and Match]]
Several combinations, each of which has a distinct merged form.

[[foldercontrol]]

[[folder: Anime and Manga ]]

* ''{{Vandread}}'': A different merged form for each girl's Dread fighter when joined with Hibiki's Vanguard mecha, plus one big gestalt robot with all four. Usually the combinations were [[DoesThisRemindYouOfAnything metaphors for sex]], with Hibiki's robot merging with a female's fighter and the sum being greater than the parts. The operators would sit in positions indicative of the relationships. [[spoiler: However, for the final form involving a male, three women, a malfunctioning robot, and an alien lifeform (praxis) all lumped together, perhaps the writers dodged the orgy metaphor and went with something like friends working together to save the day.]]
* ''Manga/GetterRobo''. The first combiner robot, with three separate combinations depending on the order of its three component vehicles.
* The same idea was taken further with ''Lightspeed Electrogod {{Albegas}}'' (the "lost ''Voltron''" -- plans to be incorporate it as a third chapter were scrapped, but Voltron-branded toys were still distributed in America); its three component robots had six combinations.
* X-Head Cannon, Y-Dragon Head, and Z-Metal Tank from ''Anime/YuGiOh'' can each combine with one other of those three to create XY-Dragon Cannon, XZ-Tank Cannon, or YZ-Tank Dragon. Or, they can all combine together to create XYZ-Dragon Cannon. In ''Anime/YuGiOhGX'', V-Tiger Jet and W-Wing Catapult were added: these could combine with each other to form VW-Tiger Catapult. That could then combine with XYZ-Dragon Cannon to form VWXYZ-Dragon Catapult Cannon, the most blatant version of this trope in ''Yu-Gi-Oh''. GX also features Assault Cannon Beetle, a monster which uses an identical set-up to XYZ.
* In '' SonicX'', Dr. Eggman has creations called Bang, [=BaBang=], and [=BaBaBang=] (admittedly, he had trouble coming up with the names) that combine into two forms, the [=EggFort=] 2 ([[ShoutOut which bears a suspicious resemblance to the]] [[Franchise/StarTrek Starship Enterprise]]), and the HumongousMecha E-99, the Egg Emperor (or Eggsterminator in the dub). Additionally, his [[MechaMooks robot henchmen]] Decoe and Bocoe had a few combination features of their own (although the one featured in episode 48 was pure fantasy, and the monster they were facing off with [[DisneyDeath appropriately reacted when its expectations were crushed]]).
* ''ZettaiMutekiRaijinOh'''s featured combination sequence merges the humanoid Ken-Oh, the lion Juu-Oh, and the avian Hou-Oh to form Raijin-Oh.
* In ''GaikingLegendOfDaikuMaryu'', the skulls of the Daiku Maryu and Daichi Maryu, and the crest of the Tenku Maryu all combine with the respective Parts 1 and Parts 2 units to form Gaiking, Vulking, and Raiking, respectively. Gaiking can combine with any of three support vehicles to form either: Buster Gaiking, giving it a BFG; Sky Gaiking, allowing it to fly; Diver Gaiking, allowing it to operate underwater; or finally Triple Gaiking, in which all three of the support vehicles combine with it at once. Finally, later on in the series, the strongest parts of each of the mecha - Daiku Maryu's skull, Raiking Parts 1, and Vulking Parts 2 - can combine together to form a robot with ten times the [[AppliedPhlebotinum Flame Power]] of the original Gaiking, called Gaiking The Great.

* The Choukijin in ''VideoGame/SuperRobotWars'', based on TheFourGods.
* In ''{{Contra}} [[NintendoHard Hard]] [[PunnyName Corps]]'', [[http://www.youtube.com/watch?v=bmFCAdLWZnc one of the stages]] had your character(s) fight against [[NinjaPirateZombieRobot an aeroplane robot, a sea-urchin robot and a dolphin robot]] as the [[MiniBoss minibosses]]. After the three get their asses handed to them (and escape), they merge together to form [[SequentialBoss a large running robot, a robot bird, and a robot-tank hybrid respectively]] before attempting to merge one last time and [[StuffBlowingUp exploding spectacularly instead]]. The boss, is in fact similar to ''GunstarHeroes''' Seven Force.
* ''GroundControl 2'' has the alein race using bio-technology, allowing them to combine to form totally diffrent units.
* ''GanbareGoemon'' 3 had the Big Bad, Jurokubei, use a huge lion mech flanked by two small snake mechs, eventually the lion would become a torso with head and legs while the snakes became the arms, creating a giant samurai robot. It then glides up to Impact, drawing it's swords threateningly... then the incompetent cross-dressing second in command, Bismaru, flies in his nun-head escape pod and lands right on top of the enemy mech, offering no benefit at all and making it look plain ridicuous. Jurokubei is left wailing about how Bismaru ruined his big scene.

* Gofotron in the "GOFOTRON: Champion of the Cosmos" storyline [[http://www.sluggy.com/daily.php (starts here)]] in '''SluggyFreelance'', a parody of ''Voltron''. It consists of six sections. [[spoiler:Including the crotch.]]

[[folder: Western Animation ]]

* The Seacons, Generation 1 ''[[WesternAnimation/TheTransformers Transformers]]'' latecomers, used the usual "four limbs plus the commander as torso" combination, but actually had six members; whichever subordinate was left out could transform into a gun for the combined form.
** The aforementioned "four limbs plus the commander as torso" configuration was actually used for several combiners starting in the second season of G1--called the "Scramble City" combiners after a [[NoExportForYou Japan-only]] {{OVA}} that heavily involved them and showed off the limb-switching gimmick. They were originally the Aerialbots/Superion, the Protectobots/Defensor, the Stunticons/Menasor, and the Combaticons/Bruticus, and season three would add the Technobots/Computron and the Terrorcons/Abominus. They could use the four smaller robots as limbs completely interchangeably--even switching arms/legs between teams (at least with the toys). Behold [[http://tfwiki.net/wiki/Abomenaticus Abomenaticus]]! (Takes parts from Abominus, Menasor, and Bruticus.)
*** And in ''Anime/TransformersEnergon'', there were three combiners that worked like this, named in homage to G1 combiners: Superion Maximus, Bruticus Maximus, and Constructicon Maximus. They couldn't interact with the G1 toys but they could interact with each other in the same ways that the G1 Scramble City combiners could. In a similar vein, almost every Autobot in ''Energon'' had the [[FusionDance Spark of Combination]]; any two Autobots of similar size with this ability could combine into a (slightly) larger robot.
**** The toys even represented this with a more one-size-fits-all transformation, as each Autobot could turn into the legs or the torso. The potential combinations were many - far more than the show could feature.
**** The Japanese-exclusive Multiforce also did this. They could also all combine into a single large robot.
** ''Anime/TransformersRobotsInDisguise'' had non-Scramble City types that could still take on different configurations, as well as the Scramble City-type [[NamesToRunAwayFromReallyFast Ruination]], who had two preferred formations.
*** Of course, since Ruination was a redecoed G1 Bruticus, this should not be surprising.
** ''Franchise/{{Transformers}}'' likes this. A sub-line called the [[http://tfwiki.net/wiki/Micromaster_Combiner Micromaster Combiners]] consists of pairs of robots who combine to form single vehicles. Though each had a specific partner, one of the selling points was that any two Micromaster Combiners could combine, even if the resulting vehicle was... [[http://tfwiki.net/wiki/Image:Micromastercombiners-mixandmatch.jpg unconventional]]. Or, for that matter, ''[[http://tfwiki.net/wiki/Image:Micromastercombiners-fronttofront.jpg outright insane]]''.
*** This was later played on and deconstructed in the second film. Skids and Mudflap have the combined form of a 1930's ice-cream truck. However, during the opening chase scene, they take a corner too sharply, split apart, and careen into a wall.

[[folder:Mecha Expansion Pack Augment]]
A smaller mecha simply attaches to a larger one, usually as a weapon or a bit of armor.

[[foldercontrol]]

[[folder: Anime and Manga ]]

* ''Anime/MazingerZ'' is the first example - the robot is powered by dropping a small aircraft (the "pilder") onto its head. And then it is combined with a JetPack to allow it fly.
** ''Anime/GreatMazinger'' is also powered by a small aircraft docks on its head.
** ''Anime/UFORoboGrendizer'' combines with a space ship to shape a starship. It also combines with different JetPack to allow it move on space, underwater or underground.
** ''Anime/ShinMazinger'' took this up a notch with the [[JetPack God Scrander]] which allowed Mazinger Z to transform into ''a giant fist''.
* Lagann of ''TengenToppaGurrenLagann'' has the power to hijack and combine with any other significantly sized machine, and can even combine ''those combinations''. First with the Gurren to form the Gurren-Lagann, and that with the city-sized [[CoolStarship Arc-Gurren battleship]] to [[http://www.youtube.com/watch?v=9rfKf8JLnbY form]] the [[MetaMecha Arc-Gurren-Lagann]], and finally [[spoiler:''that'' with the moon-sized [[CoolStarship Hyper-Galaxy DaiGurren]] to form [[MetaMecha Hyper-Galaxy Gurren Lagann]]]]. Kamina literally ''cites'' the [[strike:RuleOfCool]] [[HotBlooded Rule of Manly Spirit]] as justification, and haphazardly shoves his partner's mech into his by the drill protruding from the bottom of it in the third episode, looking incredibly stupid for his efforts until ''it actually works.'' Unlike most other instances, the combination is incredibly kickass.
---> '''Viral''': ''How is he suddenly able to power up like this?! All he did was tack on the mini-Ganmen!!''
** However it's subverted/parodied in one instance of the manga, when Kamina decides combining them the same way every time isn't "artistic" and [[http://www.onemanga.com/Tengen_Toppa_Gurren_Lagann/7.5/07/ tries to form "the Lagann-Gurren"]].
** There's actually a subtle, and ''really'' bad pun in that Simon, whose name is based on ''below'' is on the top and Kamina whose name roughly means ''above'' (it's a series thing; everyone lives underground), is on the bottom of the Gurren Lagann combination. Told you it was a bad pun.
** Amidst all of this, one of the lesser known one was Gurren Lagann's wings, which is literally another stolen mecha (one that Simon skewered) and morphed into it's engine and wings. Unlike other examples, this was a rather permanent addition (It was removed once, but to be used ''as a makeshift weapon'').
** You all forgot to mention when the Chouginga Gurren Lagann combines with the ''hotblood of the Dai-Gurren Brigade'' to form [[TitleDrop the mech the series was named after]]. The resulting combination [[spoiler:''erupts through the center of a galaxy it stands on top of, is [[IncendiaryExponent constantly on fire]], and has like 13 heads, including one IN THE MOUTH OF ANOTHER''.]]
*** ''[[UpToEleven Taken even further]]'' in the second movie, a recap of the second part of the series. [[spoiler:Tengen Toppa Gurren Lagann is torn apart, but the dozen+ pilots are able to form their own individual giant mecha ''on the same scale, '''then combine those'''''. [[http://www.youtube.com/watch?v=aS62KmYlm4k Words cannot describe it, so watch it in action.]]]]
* Certain ''Franchise/{{Gundam}}'' series had CombiningMecha of this type, most notable among which are the original Gundam, where the combined forms were added due to [[MerchandiseDriven merchandising concerns]].
** Most notable: ''[[Anime/MobileSuitGundamZZ Gundam ZZ]]''[='=]s Gundam was formed by three fighters, and ''[[Anime/MobileSuitGundamSeedDestiny Gundam SEED Destiny]]'' had the Impulse which was made up by variable fighter jets. In ''[[Anime/MobileSuitGundam00 Gundam 00]]'' Gundam 00 can also be powered up by enabling the 0 Raiser as a kind of attached catalyzer.
** ''[[Anime/MobileSuitVictoryGundam Victory Gundam]]'' had not only Victory Gundam as a combination of three fighters, but some of the atmopheric mobile suits had an upper torso that could turn into a helicopter, and a seperate "leg unit" that followed the cockpit around which would be attached to make a full mobile suit.
** In some sort of weird variation of this, the S-Gundam from ''Manga/GundamSentinel'' has the components and trappings of a Combining Mecha, including separate cockpits, but is usually piloted by one human pilot and a very advanced AI.
* The BraveSeries (which ''GaoGaiGar'' hails from) does this with incredible frequency. Every single series has the main hero mecha combine with at least one larger support vehicle to form his main "super" robot mode. This form then almost always mid series gets a second robot who combines with it as well to form a "Great" form. Additionally, one of the secondary mecha teams usually gets an extra member (who becomes additional armor and weapons). From Brave Express Might Gaine onwards, there is also typically one mecha in the series who forms a weapon for the main robot. Usually this is a gigantic cannon, but on some occasions, it takes the form of a huge sword or the legendary Goldion Hammer in ''Gao Gai Gar''.
** ''{{GaoGaiGar}}'', where several vehicles combine with a central lion-robot to make it larger and more powerful. (Original only - later versions from ''FINAL'' replaced the core or the peripherals.)
*** Oddly on its first appearance they were still working on some of the sequence and it ended up banging the parts up pretty badly.
* ''{{Gravion}}'', likewise has four vehicles combining with a central bot.
** In Gravion Zwei, the second season, there is a second mecha with also four vehicles upgrading the central bot. The vehicles cas be swapped between the two bots, and one of the bots can be upgraded by the eight vehicles and the other bot.
* In ''DennouCoil'', Satchii and its copies can dispatch spherical patrol units, equipped with beam weapons. These can be re-assembled into pre-allocated slots, enabling the base unit to [[BeamSpam fire them all at once]]. Satchii differs from the other examples by being ''purely virtual'', but since most of the show's characters dwell in cyberspace it is still considered a major threat.
* ''Blocker Gundan IV Machine Blaster'' combined the concept of ''MazingerZ'' with Franchise/SuperSentai - instead of one robot with a piloted aircraft that would attach to it, there was a team of four, each robot with its own piloted aircraft that formed the robot's head.
* The Magnemite, Beldum, and Klink lines from ''Franchise/{{Pokemon}}'' actually do this to evolve.

* The Heisei era [[Franchise/{{Godzilla}} Mechagodzilla]] could dock with a futuristic aircraft called the Garuda for extra firepower and flying capability.

* This is effectively how the Chimerae in the ''Visions'' expansion of ''MagicTheGathering'' work. Each chimera is an artifact creature that can be sacrificed to put a token granting its own power, toughness, and special ability (flying, trample, vigilance, or first strike) on another chimera. If you combined one of each of those chimerae together (just make sure you never sacrifice the one you put the first token on), you'd end up with an 8/8 monstrosity with all four of the above-mentioned abilities. Amusingly, since the rules text don't specify ''artifact'' chimerae, it would become possible to attach the Visions creatures first to Mistform Ultimus, then the changelings in Lorwyn and Morningtide (in both cases, we're talking about creatures that count as every creature type at once--chimerae included), and finally ''actual, biological'' chimerae in ''[[ClassicalMythology Theros]]''.

[[folder: Video Games ]]

* The Huckebein MK III in ''VideoGame/SuperRobotWars'' could combine with the R-Sword into the Huckebein Boxer, or ''be'' combined with the AM Gunner ship to form the Huckebein Gunner.
** ''[=SRX=]'' also had an addon in the form of the R-Gun, a mecha whose main purpose is to transform into a huge gun. It was decent on its own, but could perform the ridiculously powerful Heaven And Earth One Shot Sure Kill Cannon combo attack with SRX, an attack so powerful that in at least one game, it could kill ''the final boss'' in one shot.
* Rush and Treble to ''VideoGame/MegaManClassic'' and Bass, respectively.
* An AwesomeButImpractical example of this is [[NamesToRunAwayFromReallyFast Nod Avatar Warmech]] from ''CommandAndConquer 3''. It would literally rip pieces off of allied vehicles to upgrade itself; in the end you could have an invisible GiantRobot with dual [[ArmCannon lasers]], with a flamethrower and stealth detectors for good measure. This is somewhat worse that it sounds, since not only do you have to sacrifice a unit for every Avatar you upgrade, it takes time and micromanagement away from a better purpose (like using your tanks AND Avatars to crush your enemies). It could be somewhat useful, however, if your opponent is also Nod, because you could make your Avatar stronger and instantly destroy their vehicles.
** It's strong armor does make up for the traditional NOD weakness where their tools can [[{{GlassCannon}} dish out the pain but can't take it.]] Of course multiplayer is too fast paced to ever get the upgrades done but in the campaigns you can just turtle up untill you are ready to unleash the unstoppable mecha goodness.
* In ''VideoGame/{{Xenogears}}'', Jessiah's Buntline [[HumongousMecha Gear]] transforms into a mecha-sized handgun for his son's Renmazuo... with the cockpit as the bullet.
** [[spoiler: Hey, he made sure to fix that little design flaw before he piloted it.]]
* The Sturmvogel from ''VideoGame/{{Einhander}}''. Once you damage the main body enough, it calls in an armored unit to attach on top, starting the [[SequentialBoss second part]] of the boss fight.

* The Mini-Cons from ''Anime/TransformersArmada'' were mostly this.
** To confuse the matter, several Mini-con teams could combine into something larger - Perceptor was the main three Minicons combined into a robot, but other teams could combine into Transformer-sized weapons; the [[CoolSword Star Saber]], [[LuckilyMyShieldWillProtectMe Skyboom Shield]] and [[WaveMotionGun Requiem Blaster]].
** Also in ''Transformers Armada'', Optimus Prime's combinations with Jetfire and Overload (sometimes at the same time) and Megatron's combination with Tidal Wave were exactly this. This also showed up in several other series:
-->* ''Masterforce'' - Ginrai + Godbomber (aka "God Ginrai")
--> ''Victory'' - Starsaber + Victory Leo (aka "Victory Saber")
-->* ''[[Anime/TransformersRobotsInDisguise Robots in Disguise]]'' - Optimus + Ultra Magnus (aka "Omega Prime")
-->* ''[[Anime/TransformersRobotsInDisguise Robots in Disguise]]'' - Optimus + his vehicle mode's rear section (aka "Battle Mode")
-->* ''[[Anime/TransformersArmada Armada]]'' - Optimus + Jetfire (aka "Jet Convoy" and "Jet Optimus" at different times; see InconsistentDub.)
-->* ''Armada'' - Optimus + Overload
-->* ''Armada'' - Optimus + Jetfire + Overload
-->* ''Armada'' - Optimus + his vehicle mode's rear section (aka "Super Mode")
-->* ''Armada'' - Megatron/Galvatron + Tidal Wave
-->* ''[[Anime/TransformersEnergon Energon]]'' - Optimus + Wing Saber (in a "Flight" configuration and a "Lots of Guns" configuration)
-->* ''Energon'' - Optimus + Omega Supreme (aka "Optimus Supreme")
-->* ''Energon'' - Optimus + ''drone vehicles contained in'' his vehicle mode's rear section (aka "Super Mode" Again)
-->* ''Energon'' - Optimus + Omega Supreme + super mode drones
-->* ''[[Anime/TransformersCybertron Cybertron]]'' - Optimus + Leobreaker (aka "Savage Claw Mode")
-->* ''Cybertron'' - Optimus + Wing Saber (again, aka "Sonic Wing Mode." This name is not used in ''Energon.'')
-->* ''Cybertron'' - Optimus + his vehicle mode's rear section (aka "Super Mode.") ([[OverlyLongGag Yet Again.]])
-->* ''Cybertron'' - Megatron/Galvatron + Nemesis Breaker (aka "Dark Claw Mode")
-->* And in the second movie, ''Film/TransformersRevengeOfTheFallen'' - Optimus + Jetfire (again)
-->* And in the ''third'' movie, ''Transformers: Dark of the Moon,'' Optimus + his vehicle mode's rear section (as usual.)
* In ''Franchise/TransformersGeneration1'', Megatron turned into a gun which was wielded by other Decepticons, usually ''Starscream,'' [[TheStarscream of all 'cons]] in what could be most bland combination ever ([[MundaneMadeAwesome Gun Combined with person to become person with a gun!!!]])
** Megatron is usually thought to be unable to fire on his own, but he is seen firing himself in the opening sequence and ''once ever'' in show, suggesting he can when he really, really wants to. Maybe it's aiming that's the problem.
** The Headmasters, Targetmasters, and Powermasters, in which mobile suits for human(oid) partners became the heads, weapons, or ''engines'' for larger Transformers, respectively.
** In the Japanese post-G1 sequels, Headmasters were smaller Cybertronians from the planet Master linking up with giant non-sentient robot suits called Transtectors (basically, think of the cartoon version of Scorponok and Fortress Maximus. The larger robots that Zarak and Spike[=/=]Cerebros combine with would be called Transtectors in Japan.) Powermasters were called Godmasters and were humans in mobile suits[[note]]They're donned ''PowerRangers'' style by the use of [[TransformationTrinket Master Brace wrist devices]] and a [[ByThePowerOfGreyskull transformation call]] linking with Transtectors.[[/note]] Headmaster Juniors were also suited human sidekicks linked with Transtectors. Targetmasters were Master robots partnered with real, living Transformers.

* Parodied in ''Manga/OnePiece'', where, to fight the massive zombie Oars, Franky, Chopper, Usopp, Zoro and Sanji "combine" (really just stand on each other) into a massive humanoid figure dubbed "Big Emperor". It didn't do anything besides add extra comedic value, because Robin refused to "dock in" as the left arm, claiming that it would be "too embarrassing".
** In ''One Piece: Unlimited Cruise 2'', they do this again, with Luffy and Brook joining in.
*** And then there's Chapter 636, where they play the trope completely straight, with the [[RhinoRampage Black Rhino]] [[CoolBike FR-U #4]] combining with [[StockDinosaurs Brachio]][[TankGoodness Tank #5]] to form the humanoid "Iron Pirate Franky Shogun".
** At least, ''One Piece'' protagonists are physically strong enough to "combine". Normal people, on the other hand... courtesy of SluggyFreelance, see [[http://www.sluggy.com/comics/archives/daily/20060419 here]].
** Similary done in the LIVE-ACTION Hong Kong film Holy Weapon (1993). The Seven Virgins are played by some of Hong Kong's most famous actresses. And they actually fight. Don't miss it!
* ''{{Gekiganger 3}}'' from ''MartianSuccessorNadesico'', which includes both a Mix-And-Match style robot (an {{Expy}} of GetterRobo) and ''two'' augmentations for its MidSeasonUpgrade, Gekiganger V (Dragonganger and Spaceganger).
* ''Manga/GetterRobo'' is the ''ultimate'' example of CombiningMecha as it is capable of combining with absolutely anything, mechanical or not and transforming them into mecha. This has included living people, nuclear missiles, ''THE DINOSAURS'', Mars and other planets and eventually [[spoiler: an entire freakin' ''GALAXY'']].
* The Scavengers team from ''[[BattleAngelAlita GUNNM: Last Order]]'' ended up being cannon fodder when Toji just punche the crap out of them once they combine like Voltron with a series of Electromagnetically accelerated punches. To make it even worse, their appearance did not last 2 panels.
* In ''SuperDimensionFortressMacross'', the title's vessel was originally a [[NeglectfulPrecursors Supervision Army]] gunship capable of space travel. When it [[PortalCut sliced away Macross Island and a bit of the surrounding ocean]], the submersible landing vessel and aircraft carrier ''Daedalus'' and ''Prometheus'' were taken along for the ride, and somehow attached to the Macross ship. ''Then'' they reconfigured the vessel to turn into a HumongousMecha, with these ships taking the place of its arms. In the visual continuity sprouting from ''[[TheMovie Do You Remember Love?]]'' the ''Daedalus'' and ''Prometheus'' were replaced with two ARMD defense cruisers that were already in orbit when the Macross folded into outer space.
** IIRC, ARMD I and II were supposed to link to the Macross anyway, but the Zentradi prevented them from achieving this in the series. And then when the Macross used the [[FasterThanLightTravel Fold system]] they took along the ''Daedalus'' and ''Prometheus'' (killing the crews of both ships in the process) and so had no choice but to use them instead. They needed the defensive weaponry and runways provided by the two ships.
* Not sure where else to put it, since the characters are both the pilots and somewhat their own Mecha. Anime only ''{{MAR}}'' characters, the Flat Sisters: Grave, Allegro and Moderato form Rotkappchen Waltzer, what looks like a giant rag doll.
* ''Anime/KotetsuJeeg'', from the creator of ''Anime/MazingerZ'' and ''Manga/GetterRobo'', has an interesting version: the protagonist is a cyborg who transforms into a giant head, which then combines with man-made parts to form a HumongousMecha. In the {{Revival}}-slash-AlternateUniverse sequel ''KoutetsushinJeeg'', a transforming motorcycle forms the head of Koutetsushin Jeeg, which otherwise functions exactly like its precursor.
** Which was probably the inspiration for the Headmasters of various ''Transformers'' series, which were people in special PoweredArmor that lets them turn into the head of a Transformer to make it stronger.
*** There's also Targetmasters (gun) and Powermasters (engine.)
* The Machine Emperors from ''YuGiOh5Ds'', made up of five different types of monster cards ('Core', 'Top', 'Guard', 'Attack', and 'Carrier'). The 'Wisel' cards form a giant humanoid, the 'Skiel' cards form a giant bird, and there's supposedly [[RuleOfThree a third set]] which has yet to be revealed. They can be powered up by using stronger versions of the individual cards. They can even be mixed between two different creatures, i.e. creating Wisel with a Skiel Carrier card produces a Wisel with wings where it's legs should be.
** As of episode 110, the 3rd Machine Emperor, Grannel, has been revealed, taking the appearance of a giant gold golem-like creature.
** It has the form of a tank, with a cannon.
* ''MiraiRoboDaltanious'', which was originally intended to ''Voltron'', involves a combination of a humanoid robot, a lion, and a vehicle - the same types of mecha used by Albegas, Golion, and Dairugger, the shows that '''did''' become ''Voltron''.

* This was the main gimmick of the {{Capcom}} ShootEmUp ''SideArms'': by picking a certain power-up, one player could combine their mecha with the other player's to form a more powerful mecha controlled by both.
* As an April Fool's Day joke, [[BlizzardEntertainment Blizzard]] showcased a new unit for the [[VideoGame/{{Starcraft II}} Terrans]]: The [[http://us.starcraft2.com/features/terran/terratron.xml Terra-tron]], which is formed by combining ALL OF THE BUILDINGS IN THE AREA into a [[BiggerIsBetter huge]] [[ImmuneToBullets mecha]]. It is loaded with shout-outs to other famous uses of this trope, just listen to [[StopPokingMe its dialogue]].
* The [[http://accelagirl.deviantart.com/art/ZOMBITRON-109055272 special infected in this]] VideoGame/Left4Dead FanArt.
* In ''Film/TheMatrix: Path of Neo'', the final boss is [[spoiler:a giant Agent Smith constructed by all the Smiths from various debris, topped with giant sunglasses ripped from a billboard]].
* In ''VideoGame/MarioAndLuigiDreamTeam'', Earthwake, one of the [[AttackOfThe50FootWhatever giant bosses]] is one of these composed of ''buildings.''

* Parodied again in [[http://nedroid.com/2010/06/battle-ready-extra-ready/ this]] ''{{Nedroid}}'' comic, along with HotBlooded mecha animé in general.
* Also parodied in [[http://pbfcomics.com/?cid=PBF186-Guntron_Alliance_Force.jpg this]] ''PerryBibleFellowship'' comic.
* When ''{{Wonderella}}'' gets lazy, [[http://nonadventures.com/2006/12/16/fae-to-black/ "Faerie Force is GO!"]]
* Both parodied and played straight in ''{{Operator}}'': After forcibly combining his opponents' mech with his own [unusually, an irreversible process that forced the other guy to abandon ship], Griff later has a dream about 'combining' that is a direct ShoutOut to GurrenLagann
* Similar to the OnePiece example above, {{Paranatural}} also features humans attempting to combine into a mecha form, in this case three bullies standing on each other's shoulders, a.k.a the "Friendship Fusion!"

* In the [[ImageBoards /v/]] [[http://www.youtube.com/watch?v=YVys7jcCJDs Rage Flash]] a mecha is made out of VideoGameSystems, but it collapses because:
-->'''Concoles can't combine you FAGGOT'''

[[folder: Western Animation ]]

* ''WesternAnimation/MegasXLR'' has animal-to-robot ones that were damaged when Coop uses them as impromptu augmentation for Megas. This shows why they must be ''designed'' for that purpose, as he more or less just crammed his arms and legs up their mecha asses, and wrecked them so heavily as to drive one of the pilots to tears and [[EvenEvilHasStandards elicit shock from]] the EvilOverlord: "I thought ''I'' was evil. That's just ''mean''." Though ironically, it still manages to give Megas the needed power boost to defeat said EvilOverlord.
** As another example from the same series, in the first episode (and the ''Lowbrow'' pilot), five Glorft robots combine into a giant humanoid mecha... and six of ''those'' mecha combine into an even bigger mecha, with Gorrath's spider-like mecha forming the head. It's as ridiculous as it sounds.
* Joe and his wheelchair buddies from ''WesternAnimation/FamilyGuy'' apparently have the power to form [[http://www.youtube.com/watch?v=H5p90_0SFRw Crippletron,]] and unlike the other parody examples, the thing actually ''works''.
* In the fight on ''WesternAnimation/CelebrityDeathmatch'' between Music/{{NSYNC}} and The Music/BackstreetBoys, each boy band had a combiner form they used in the ring.
** Actually The Backstreet Boys were the only ones to form one. It was called the "Backstreet Beast"
*** *NSYNC did form some spinning rotor-like object that had their toenails as blades
** This was also parodied/[[{{Homage}} homaged]] in WesternAnimation/RobotChicken with "Enter the Fat One" (along with Film/EnterTheDragon and Film/TheKarateKid--including Pat Morita); Music/BritneySpears [[BodyHorror "combines"]] with fellow artists Music/ChristinaAguilera, Music/AvrilLavigne, Music/JessicaSimpson, [[MyFriendsAndZoidberg and]] [[Music/AshleeSimpson Jessica Simpson's sister]] as the FinalBoss. Joey in turn gains the [[ThePowerOfFriendship power of his bandmates' souls]] and grows to an equal size to defeat the girl-monster.
* In ''WesternAnimation/TheVentureBrothers'', the Venture twins' overactive imagination during a witness testimony in a court case against the Monarch culminates in them combining together to form "Mecha Shiva", which they reenact in the court room.
* The villains of ''TheFairlyOddparents'' HalloweenEpisode were four pumpkin-like robots called the Jack O'Bots who formed into one big machine called the Pumpkinator (or rather, the four [[RichBitch popular kids]] wearing the costumes when Timmy [[BecomingTheCostume made his wish]]).
* Anubian in ''{{Huntik}}'' is a [[{{mons}} monster]] that acts like a CombiningMecha. Five flying bug-eyeball-things combine with a torso to create the creature.
* ''WesternAnimation/DextersLaboratory'' has a parody of this in one episode - all of Dexter's family members control a different section of the combined robot, and thus are out of sync until they figure out how to work together. In fact, they even have to switch places early on because they had no idea how to properly use the individual limbs.
* ''WesternAnimation/AdventureTime'' did this with the Body parts people that the Magic Man created.
-->'''Jake''': ...and I'll form...the pants.
* The three magic totems in ''PawPawBears'' played this role.
* ''SuperRobotMonkeyTeamHyperforceGo'': The Super Robot can split into six combat vehicles and reform whenever the Hyperforce wants it to.
* Duncan of TotalDramaIsland found capturing a raccoon to be more difficult than anticipated (even with [[NoKillLikeOverkill his chainsaw]]), when a swarm of them combine into a giant raccoon-bot, complete with GlowingEyesOfDoom.
--> Duncan: [[ShoutOut Well that's]] [[Franchise/{{Transformers}} more than meets the eye]]...
