"Form, feet and legs!"
"Form, arms and body!"
"...and I'll form ... the head!"


Cquote1
"Constructicons! UNITE!"
Cquote2


When two or more independent Mecha can combine to make another, larger mecha. It can be a decent way to hide a really big robot in plain sight, by breaking it up into pieces.

After the merge (accompanied by the stock Transformation Sequence), the new mecha will have powers and abilities greater than the sum of its parts. Combining Mecha are frequently a metaphor for Team Spirit and/or The Power of Friendship because of this.

It's common to find these in the same places as Transforming Mecha—indeed there are many that can do both. A frequent source of Technology Porn.

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 Super Sentai and Power Rangers 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. The Hero) 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 become the literal head of the combined form? This also eliminates the requirement for more than one Transformation Sequence, 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 So Last Season status, with the mecha rarely used for anything other than their ability to combine. This is certainly the case with, for example, most Super Sentai and Power Rangers series, where once the team's Megazord is revealed (usually at the end of the Pilot Episode), they will never use anything less. (Probably because hiring People in Rubber Suits to fight the Monster of the Week is a lot less expensive than the Stop Motion or CGI required to animate individual mecha doing the same.)

In cases where the mecha are sapient beings with no outside pilot (such as 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 Dumb Muscle whose vocabulary consists primarily of one-syllable words and who can only focus on one task at a time: For the good guys, this creates a Gentle Giant; 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 implausibilities of Transforming Mecha 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 Transformation Sequence, 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 Detachment Combat.

See Totem Pole Trench and The Worm That Walks for similar tropes involving living things.

Examples of Combining Mecha include:


All of the following[]

  • Super Sentai, and therefore Power Rangers, 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, Goranger, and its successor, JAKQ Dengeki Tai, never had mechas. It was on the third Sentai, Battle Fever J, that the series had a mecha (an idea taken from the Japanese tokusatsu Spider-Man), and even that mecha wasn't a combining mecha. It was only until Sun Vulcan did they introduced the combining mecha idea. And even then, it was usually two or three machines combining - the eleventh series, Hikari Sentai Maskman, 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 whatever Zord. They combine into an humanoid Megazord. Then Sixth Ranger comes with his Mecha Expansion Pack 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 were all humanoid and formed the Shogun Megazord, and the Turbo Rescuezords were like Transformers (vehicle-to-humanoid transformation) as well as being able to make a Rescue Megazord. 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 Stock Footage, 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.
    • Mecha Expansion Pack? 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 Samurai Sentai Shinkenger) or the Dual Drive Megazord of Power Rangers Operation Overdrive (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 Sixth Ranger mecha do this with the combined robot of the other Rangers.
      • Parodied in Samurai Sentai Shinkenger 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: Gosei Sentai Dairangers Dairenoh (AKA the Thunder Megazord) and Tokumei Sentai Gobusters Go-BusterOh.

Group of vehicles to giant robot[]

Anime and Manga[]

  • The Getter Robo series, which is the Trope Maker for the combining giant robot, though there had been combining robots as early as Astro Boy.
  • GaoFighGar in GaoGaiGar, which was identical to the original, but with a transforming hovercraft instead of the robot lion. (See animals-to-humanoid.)
  • Space Runaway Ideon
  • Combattler V and Voltes V (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 reproduced in toy form).
  • Zambot 3: Zambot was formed by the combination of three vehicles: an aircraft, a tank and a terrestrial support vehicle.
  • Dairugger XV (known in America as the Vehicle Voltron series).
  • Genesis of Aquarion 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.
  • The Big O 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.
  • The titular Xabungle and later the Walker Gallier are each formed out of two vehicles.
  • Dai-Guard has a realistic take on this; at first, the titular mecha 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.

Film[]

  • The MOGUERA unit in Godzilla vs. Space Godzilla.

Video Games[]

  • The Valhawk (a plane by default) and Valstork into the Valguard in Super Robot Wars W. Then, both of those plus a Valhawk-sized mecha named Arm Arcus and another battleship, the Arm Stora, into the ludicrously powerful Valzacard.
    • The Elebus and Simurgh combine into the Simurgh Splendid and Earthgain and Vyrose combine into Super Earthgain in Super Robot Wars 64.
  • In World of Warcraft, 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 V0-L7R-0N, a combination of the three which looks like a giant mechagnome.

Western Animation[]

  • The Venture Bros does have one legitimate (read: not made-up) Mecha, Jonas Venture Jr.'s Ventronic, which is most definitely a Voltron parody.
  • Parodied in Robot Chicken 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.
    • Another sketch has the evil giant monster challenge Voltron to a dance battle. And it was awesome.

Tabletop Games[]

  • The sample combiner in Mekton Plus is a tank, a submarine and a plane combining into a humanoid.

Group of humanoid robots to giant robot[]

Anime and Manga[]

  • The Symmetrical Docking pairs in GaoGaiGar, and Big Volfogg in the same series.
  • The original Astro Boy manga (which predates Getter Robo 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.
  • Magic Knight Rayearth has a variation with its three Legendary Mashin (Rune Gods). The Mashin are Humongous Mechas 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 Humongous Mecha with all three Magic Knights inside.
  • Happens all over Tengen Toppa Gurren Lagann.
    • 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 just one mecha with another drilled into its head. Then comes the Transformation Sequence.
    • In the second movie, Lagann-hen, After Lord Genome converts the 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 Shirts 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 Clipped-Wing Angel form with the 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 Up to Eleven times Over 9000 with 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 ["Energy Being|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."]
  • At the end of episode 25 of IGPX: Immortal Grand Prix, Team White Snow combines their three mechas into a giant behemoth mecha.
  • Rokushin Gattai!

Film[]

Toys[]

  • BB Senshi Sangokuden 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 Fusion Dance.

Video Games[]

  • In City of Heroes, 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.
  • The SRX (Super Robot Type X) in Super Robot Wars.
  • Xenogears, generally a Super Robot game, featured one combining mecha with Dominia and her compatriots.
  • This was later given a homage in the Xenosaga games with Erde Kaiser. In 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.

Web Original[]

  • In Ilivais X, 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 Q.

Western Animation[]

  • The Transformers practically communicate via this. Of course how easy it is varies wildly. It used to be quite easy but newer media has shifted more towards the idea that smashing five to six bots together doesn't always lead to the most harmonious fusion of minds with the Combiner usually having its own personality.
    • The original cartoon and toyline had the Constructicons (Devastator), Stunticons (Menasor), Combaticons (Bruticus), Predacons (Predaking), Terrorcons (Abominus), Seacons (Piranacon), 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.
      • In fact, a whole sub-franchise, Combiner Wars, was dedicated to this.
    • In Robots in Disguise, the 2001 anime and the 2015 cartoon, combiners were an old hat. Any two bots could combine.
    • Transformers Energon had 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.
    • Combining is such an integral part of Transformers lore that one of the Thirteen Original Primes, Nexus Prime, was made the Prime of Combination. His artefact of power, the Enigma of Combination, can merge any group of Cybertronians into a combiner or enhance pre-existing ones.
  • Mighty Orbots 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.
  • "Sym-Bionic Titan" has the main characters form the titular Titan by connecting their 2 sets of humanoid armor to an actual humanoid robot.
  • Legion of Super Heroes has possibly the ultimate example: after his Face Heel Turn, Brainiac 5 takes control of his entire species—composed of metamorphing robots linked in a Hive Mind—and when challenged by the Legion, turns all of them into a single gigantic battlebot.
  • Transformers' one time rival, Challenge of the Go Bots, had the Renegade combiners of Puzzler and Monstreous.

Group of animal robots to giant robot[]

Anime and Manga[]

  • Golion (in America, the Lion Voltron).
  • Digimon Xros Wars has this as its core gimmick setting it apart from the preceding 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.
  • Genesic GaoGaiGar. A dolphin, shark, two moles and a bird thing were substituted for the vehicles, going the opposite way from GaoFighGar.
  • Gun X Sword 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 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.
  • The central premise of the anime Zoids: Fuzors.

Video Games[]

  • The final boss of Mischief Makers was a humanoid robot formed from a wolf, ape and eagle.
    • And those could also change into a vehicule mode.

Tabletop Games[]

  • The Mekton Mecha Manual has the God-Griffon VX, formed from the God-Fang V and the God-Wing X.

Western Animation[]


Group of vehicles to bigger vehicle[]

Anime and Manga[]

  • Science Ninja Team Gatchaman
  • The Legioss and Tread fighters from Genesis Climber Mospeada could merge into a bigger aircraft, and each could independently become a robot.
  • The Thunderbirds in the anime remake (2086) which actually made some sort of sense. It's quicker to move the smaller vehicles by strapping them to the sides of the heavy lifter than to send them all independently.
  • The 15 "small" vehicles of Dairugger XV (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 Brave Series The Brave Express Might Gaine 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) Finishing Move, 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.
  • The titular vehicle in Supercar Gattiger is formed by combining its five component cars—the Center Machine, Left Machine, Right Machine, End Machine, and Back Machine.

Comic Books[]

  • Arguably, some incarnations of the Fantastic Four's Fantasti-car, which could separate into sub-vehicles for each of the Four.

Film[]

Live Action TV[]

Video Games[]

  • In the Xbox 360 freeware title Aegis Wing, 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 Wing Commander: 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.
  • Star Force 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.

Western Animation[]

  • A small handful of 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 Re Boot 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.

Mix and Match[]

Several combinations, each of which has a distinct merged form.

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 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. 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.
  • Getter Robo. 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 Yu-Gi-Oh! 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 Yu-Gi-Oh! GX, 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 Sonic X, 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 (which bears a suspicious resemblance to the Starship Enterprise), and the Humongous Mecha E-99, the Egg Emperor (or Eggsterminator in the dub). Additionally, his 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 appropriately reacted when its expectations were crushed).
  • Zettai Muteki Raijin-Oh's featured combination sequence merges the humanoid Ken-Oh, the lion Juu-Oh, and the avian Hou-Oh to form the titular Raijin-Oh.

Video Games[]

Web Comics[]

  • Gofotron in the "GOFOTRON: Champion of the Cosmos" storyline (starts here) in 'Sluggy Freelance, a parody of Voltron. It consists of six sections. Including the crotch.

Western Animation[]

  • The Seacons, Generation 1 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 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 Abomenaticus! (Takes parts from Abominus, Menasor, and Bruticus.)
      • And in Transformers Energon, 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 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.
    • Transformers Robots in Disguise had non-Scramble City types that could still take on different configurations, as well as the Scramble City-type Ruination, who had two preferred formations.
      • Of course, since Ruination was a redecoed G1 Bruticus, this should not be surprising.
    • Transformers likes this. A sub-line called the 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... unconventional. Or, for that matter, 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.


Mecha Expansion Pack Augment[]

A smaller mecha simply attaches to a larger one, usually as a weapon or a bit of armor.

Anime and Manga[]

  • Mazinger Z 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 Jet Pack to allow it fly.
    • Great Mazinger is also powered by a small aircraft docks on its head.
    • UFO Robo Grendizer combines with a space ship to shape a Starship. It also combines with different Jet Packs to allow it move on space, underwater or underground.
  • Lagann of Tengen Toppa Gurren Lagann 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 Arc-Gurren battleship to form the Arc-Gurren-Lagann, and finally that with the moon-sized Hyper-Galaxy DaiGurren to form Hyper-Galaxy Gurren Lagann. Kamina literally cites the Rule of Cool 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.
Cquote1

  Viral: How is he suddenly able to power up like this?! All he did was tack on the mini-Ganmen!!

Cquote2
    • 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 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.
    • You all forgot to mention when the Chouginga Gurren Lagann combines with the hotblood of the Dai-Gurren Brigade to form the mech the series was named after. The resulting combination erupts through the center of a galaxy it stands on top of, is constantly on fire, and has like 13 heads, including one IN THE MOUTH OF ANOTHER.
  • Certain Gundam series had Combining Mecha of this type, most notable among which are the original Gundam, where the combined forms were added due to merchandising concerns.
    • Most notable: Gundam ZZ's titular Gundam was formed by 3 fighters, and Gundam SEED Destiny had the Impulse which was made up by variable fighter jets. In Gundam 00 the titular Gundam can also be powered up by enabling the 0 Raiser as a kind of attached catalyzer.
    • Victory Gundam had not only the titular 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 Gundam Sentinel 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 Brave Series (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 Dennou Coil, 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 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 Mazinger Z with Super Sentai - 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 Pokémon actually do this to evolve.

Film[]

  • The Heisei era Mechagodzilla could dock with a futuristic aircraft called the Garuda for extra firepower and flying capability.

Live Action TV[]

Video Games[]

  • The Huckebein MK III in Super Robot Wars 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 Classic Mega Man and Bass, respectively.
  • An Awesome but Impractical example of this is Nod Avatar Warmech from Command and Conquer 3. It would literally rip pieces off of allied vehicles to upgrade itself; in the end you could have an invisible Giant Robot with dual 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 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 Xenogears, Jessiah's Buntline Gear transforms into a mecha-sized handgun for his son's Renmazuo... with the cockpit as the bullet.
    • Hey, he made sure to fix that little design flaw before he piloted it.
  • The Sturmvogel from Einhander. Once you damage the main body enough, it calls in an armored unit to attach on top, starting the second part of the boss fight.

Western Animation[]

  • The Mini-Cons from Transformers Armada were mostly this.
    • To confuse the matter, several Mini-con teams could combine into something larger - Perceptor was the mean three Minicons combined into a robot, but other teams could combine into Transformer-sized weapons; the Star Saber, Skyboom Shield and 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")

  • Robots in Disguise - Optimus + Ultra Magnus (aka "Omega Prime")
  • Robots in Disguise - Optimus + his vehicle mode's rear section (aka "Battle Mode")
  • Armada - Optimus + Jetfire (aka "Jet Convoy" and "Jet Optimus" at different times; see Inconsistent Dub.)
  • Armada - Optimus + Overload
  • Armada - Optimus + Jetfire + Overload
  • Armada - Optimus + his vehicle mode's rear section (aka "Super Mode")
  • Armada - Megatron/Galvatron + Tidal Wave
  • 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")
  • Energon - Optimus + Omega Supreme + super mode drones
  • 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.") (Overly Long Gag Again.)
  • Cybertron - Megatron/Galvatron + Nemesis Breaker (aka "Dark Claw Mode")
  • And in the second movie, Transformers: Revenge of the Fallen - Optimus + Jetfire (again)
  • And in the third movie, Transformers: Dark of the Moon, Optimus + his vehicle mode's rear section (as usual.)
Cquote2
  • The GoBots line had Courageous and Grungy in such roles.

Other[]

  • The 1989 Japan-only line of Zoids had Shoteagle, Gorgolauncher, and Thundercannon which plugged into larger "grade up" types after transforming into a BFG.

Other[]

Anime and Manga[]

  • Parodied in One Piece, 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 pants, 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 Kurosai FR-U #4 combining with BrachioTank #5 to form the humanoid "Iron Pirate Franky Shogun".
    • Similarly, there's Mecha-Shiva from The Venture Bros. Frankly, it's not worth explaining other than the fact that it's part of a Fake Action Prologue.
    • At least, One Piece protagonists are physically strong enough to "combine". Normal people, on the other hand... courtesy of Sluggy Freelance, see 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 Martian Successor Nadesico, which includes both a Mix-And-Match style robot (an Expy of Getter Robo) and two augmentations for its Mid-Season Upgrade, Gekiganger V (Dragonganger and Spaceganger).
  • Getter Robo is the ultimate example of Combining Mecha 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 an entire freakin' GALAXY.
  • The Scavengers team from 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 Super Dimension Fortress Macross, the titular vessel was originally a Supervision Army gunship capable of space travel. When it 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 Humongous Mecha, with these ships taking the place of its arms. In the visual continuity sprouting from 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 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.
  • Kotetsu Jeeg, from the creator of Mazinger Z and Getter Robo, 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 Humongous Mecha. In the Revival-slash-Alternate Universe sequel Koutetsushin Jeeg, a transforming motorcycle forms the head of the titular mecha, which otherwise functions exactly like its precursor.
    • Which was probably the inspiration for the Headmasters of various Transformers series, which were people in special Powered Armor 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 Yu-Gi-Oh! 5D's, 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 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.
  • Mirai Robo Daltanious, 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.
  • In the two-part Kid Icarus short "Palutena's Revolting Dinner" from Studio Shaft, the vegetables (brought to life thanks to a rejuvination potion) fuse together to form a giant vegetable creature.

Video Games[]

  • In No More Heroes Travis Touchdown's favorite show Pure White Lover Bizarre Jelly is about three magical girls with mecha that combine to form Pure White Giant Glastonberry.
    • In the sequel, he has a version of it built for himself in the event that he's ever staring down a giant robot.
  • This was the main gimmick of the Capcom Shoot'Em Up Side Arms: 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, Blizzard showcased a new unit for the Terrans: The Terra-tron, which is formed by combining ALL OF THE BUILDINGS IN THE AREA into a huge mecha. It is loaded with shout-outs to other famous uses of this trope, just listen to its dialogue.
  • The special infected in this Left 4 Dead Fan Art.
  • In The Matrix: Path of Neo, the final boss is a giant Agent Smith constructed by all the Smiths from various debris, topped with giant sunglasses ripped from a billboard.

Web Comics[]

Western Animation[]

  • Megas XLR 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 elicit shock from the Evil Overlord: "I thought I was evil. That's just mean." Though ironically, it still manages to give Megas the needed power boost to defeat said Evil Overlord.
    • 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 Family Guy apparently have the power to form Crippletron, and unlike the other parody examples, the thing actually works.
  • In the fight on Celebrity Deathmatch between n* Sync and The Backstreet Boys, 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"
      • n*Sync did form some spinning rotor-like object that had their toenails as blades
  • The villains of The Fairly Odd Parents Halloween Episode were four pumpkin-like robots called the Jack O'Bots who formed into one big machine called the Pumpkinator (or rather, the four popular kids wearing the costumes when Timmy made his wish).
  • Anubian in Huntik is a monster that acts like a Combining Mecha. Five flying bug-eyeball-things combine with a torso to create the creature.
  • Dexter's Laboratory 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.
  • Adventure Time did this with the Body parts people that the Magic Man created.
