[[caption-width-right:330:Autobots, transform and roll out!]]

-> ''"Damn! The plane turned into a frikkin' robot!"''
-->-- '''Hikaru Ichijou''', ''Anime/SuperDimensionFortressMacross''

If one cool vehicle can help the hero out, then more than one can certainly be better, right? But if the hero is out with one, and needs the other, he's up the creek. Not so, for he's driving a Transforming Mecha, which can mechanically rearrange itself into a variety of different machines for different roles.

The most common form of this is humanoid/animaloid robot to vehicle. The vehicle and humanoid form will most often share parts, characteristics and details. For instance, big tough robots will change into trucks and tanks, while light fast robots will shift into fighter jets or sports cars. The design of the robot form is usually done using elements from the vehicle form, making it at least visually plausible that one can become the other without swapping anything out back at the shop. The vehicle form usually has an [[MultiformBalance advantage]], like a higher speed, or the ability to {{masquerade}} as a mundane vehicle.

It is, of course, also possible that the two will not resemble each other in any way, and the transformation will be based on matter replication or other semi-magical technology. The advantage to the mechanical transformation is that it's possible to design a [[MerchandiseDriven toy]] that works almost exactly like the mecha on the show.

The switchover itself will either be a full-blown TransformationSequence in SuperRobot shows, or a lightning-fast parts shuffle in a RealRobot show. There are sometimes exceptions, as with the TelescopingRobot's ability to expand outwards. A reliable source for TechnologyPorn.

A variation, sometimes used in combination, is [[MechaExpansionPack the modular parts system]], with which a mecha can re-equip with different tools and weapons for different jobs, like the FAST packs from ''Anime/SuperDimensionFortressMacross'' or the weapon systems from ''WesternAnimation/{{Centurions}}''. This type of system is in use in real-life militaries, which have such things as up-armoring kits for vehicles and universal hard-points on combat aircraft.

There is also the matter of the vehicle that transforms into the same vehicle, only ''[[RuleOfCool much cooler]]''. These are more common in shows aimed at younger audiences, but appear from time to time throughout the genre. The typical explanation being that the cooler form is the vehicle's true form, while the ordinary one is a disguise.

The physics and logistics of the transformation concept are tenuous at best. Most of the internal space of the vehicle would have to be taken up by the robot's parts, but they usually seem to have cargo and passenger room much like an equivalent mundane craft. The extra weight of the unused robot components would probably reduce the capabilities of the vehicle form, but in most cases it's faster, tougher and overall better than the non-transforming types.

Frequently, it is possible to anticipate if a vehicle will transform into a robot form if it contains strangely [[KibblesAndBits out-of-place elements]] in its design, as if its engineers suddenly decided to ignore the laws of aerodynamics. Examples include strange protruding bulges and unnecessary giant hand-shaped areas. Most of the time, if the characters within a show are not aware of the vehicle's ability to enter a robot mode, they ignore these design quirks prior to the robot's first transformation. Much to their surprise, the robot changes form near the end of the pilot episode or the beginning of the second. Note, though, that there are certainly exceptions, with the tell-tale bits instead being alt-mode bits that are obvious in robot mode. (''{{Transformers}}'' fans refer to these as [[KibblesAndBits kibble]].)

For normal vehicles that transform, see TransformingVehicle, its SisterTrope.


* The Taiwanese military now have them. Well, according to [[http://www.youtube.com/watch?v=EpAvEX2tsr8 this ad]], at least.
* The famous dancing Citroen C4 from [[https://www.youtube.com/watch?v=CLmE4lby_fI this ad]].

[[folder:Anime and Manga]]
* The variable fighters of the ''Anime/{{Macross}}'' franchise, which are transforming fighter jets, with each series's main protagonist always piloting one. The titular ''Macross'' class of vessels are ''[[strike: the]]'' [[{{Transformers}} some of the]] largest transforming mecha ever shown on television. The original ''[[Anime/SuperDimensionFortressMacross SDF Macross]]'' was over one kilometer tall. The Battle sections of the later ''New Macross'' class vessels, when transformed into humanoid form, are ''almost a mile tall''. ''Anime/MacrossFrontier'' also has the VB-6 ''König Monster'' variable bomber, which can transform into a walking heavy artillery platform.
** Additionally, there is a reasonable explanation for the use of these mechas (well, at least the fighter-jet-sized ones), something not all [[RealRobot Real]] or SuperRobot shows care to give to the viewers, mind it. In the first few episodes of [[Anime/SuperDimensionFortressMacross the original series]], Roy Focker states that the Valkyries were designed to be able to fight "on even grounds" with the Zentradi. While most GiantRobot shows have mechs almost entirely for RuleOfCool, a quick flash of FridgeBrilliance makes one realize that "on even grounds" doesn't mean tech-wise, but the fact that using Variable Fighters (VF-1's) is the ''only'' way to engage in true infantry-based-warfare with [[AttackOfTheFiftyFootWhatever the Zentradi]], while their jet-based primary form is to provide fast, long-distance travel that would normally be provided by transport planes/choppers, and the Gerwalk transitional form exists (as stated in the show itself) as a VTOL form for difficult terrain when taking off in the Valkyrie form and landing in the Battroid form. There is a certain degree of MundaneUtility to the Gerwalk mode as well, as some supplementary materials state that this is the mode that they use to transport Valkyries around the hanger for maintenance outside of combat; it's also often used to pull off maneuvers that wouldn't be possible with a regular jet, like using the leg boosters to quickly reverse direction and get behind an opponent.
** The original ''Macross'' transformed into a humanoid configuration due to losing a lot of its power conduits during the space fold disaster: the human shape was them taking advantage of the modular nature of the ship to connect the remaining conduits to fire the [[WaveMotionGun Macross Cannon]]. That it looked human-shaped when this happened was apparently coincidental. Later ''Macross'' and ''New Macross'' class vessels keep the transformation because... uh, well, they never really say. RuleOfCool, perhaps. Or because it's the only way to pull off the ''[[RammingAlwaysWorks Macross]] [[MegatonPunch Attack]]'' that was pioneered originally as the ''Daedalus Attack'' as a desperate move in the original series. It ''does'' work.
** While not the UrExample of this trope, ''Macross'' may be responsible for popularizing it, not just because it was brought over to the west as part of ''Anime/{{Robotech}}'', but also because the success of Takatoku's ''Macross'' toy line led to Takara releasing their ''Diaclone'' line which became the basis for ''Franchise/{{Transformers}}''. In fact, the Autobot Jetfire was made from the same mold as the VF-1 Valkyrie from Macross.
* ''Anime/{{Daimos}}'': The titular HumongousMecha was one of the first ones. He could transform into a rocket-shaped spaceship.
* ''Manga/GetterRobo'' in all its incarnations was both a CombiningMecha and a Transforming Mecha.
* Many of the LFO mechs in ''Anime/EurekaSeven'' can transform into land vehicles.
* Franchise/{{Zoids}} were mostly monoform, but Liger Zero from ''Anime/ZoidsNewCentury'' has a modular swap-out system.
* In ''Anime/SonicX'', Tails's plane Tornado II transforms from a plane into a ''really fast'' plane. Later, he adds a bipedal mecha transformation. These come from directly from the games: ''Sonic Adventure'' features Tails's Tornado transforming from one plane into another (with no actual effect, really), while Tails runs around in the bipedal mecha in ''Sonic Adventure 2''.
* All of the robots in ''King of Braves Anime/GaoGaiGar'' could transform. And ''then'' they started [[CombiningMecha combining with each other and bolting extra bits on]].
* Another very early example was Pook (from the slavic (or was it Celtic?) word Pooka, a type of animal spirit) from ''Manga/{{Astroboy}}'', a robot kid who could turn into a variety of animals before his transformation system was destroyed by trying to change into too many things too fast. In the GBA game he also becomes a CombiningMecha, gaining the ability to change into the "heart" of the planet destroying alien robot Garon. Transformers show up a few other times in Astroboy, including Odette, a robot ballet dancer who turns into a swan who was created for a fairytale theme park attraction based on ''Theatre/SwanLake''.
* The SuperRobot ''Anime/{{Raideen}}'', who debuted around the same time as ''Manga/GetterRobo'', was probably the first straight-up example of a giant robot who became a vehicle, turning into a bird-themed aircraft.
* ''Franchise/{{Gundam}}'': In "rough" order.
** ''Anime/MobileSuitGundam'': The original (titular) RX-78-2 Gundam is a partial example, with its core-fighter and G-Fighter components. Unlike many, it's a single suit with one mode, and straddles this trope and CombiningMecha.
** ''Anime/MobileSuitZetaGundam'': The Zeta Gundam which transforms into a plane design for greater speed.
*** A lot of the other mecha in Zeta can transform, including the Methuss, Gaplant and Asshimar. The Hyaku Shiki was designed as a transforming mecha but it didn't quite work. The ''Advance of Zeta'' side-stories add even more.
** ''Anime/MobileSuitGundamZZ'': The ZZ Gundam's G-Fortress mode.
** ''Anime/MobileSuitGundamUnicorn'': continues the trend with the Loto (MS to Tank), Delta Plus, [=ReZEL=] and Ankusha (MS to Flight Form); the latter two can carry friendly MS into battle while transformed. The titular Unicorn also transforms, from an ordinary mobile suit with a Unicorn horn to a [[TurnsRed red-glowing]] [[SuperMode Gundam of death]].
** ''Anime/MobileSuitVictoryGundam'': Victory 1 & 2 Gundams which transform ''and'' combine.
** ''Anime/MobileFighterGGundam'': The Nether Gundam, which can [[WhatKindOfLamePowerIsHeartAnyway turn into a windmill]] (yes, really). The Heaven's Sword Gundam, which has a bird-like flight mode and a fighter mode. And then there's the Devil Gundam, which keeps coming up with more and more new forms as the series goes on.
** ''Anime/MobileSuitGundamWing'': The titular Gundam (known in series as "Unit 1") can go from Bird mode to Mobile Suit mode and back, and [[SuperPrototype Wing Zero]][[note]]The prototype for ''all'' the gundams, making it a double SuperPrototype[[/note]] could transform as well. Epyon transformed into a dragon-shaped mecha. Gundam Wing Endless Waltz changed the designs, however.
*** The Taurus as both mobile suit and mobile doll had a "fighter" mode capable of atmospheric flight and higher speeds.
** ''Anime/AfterWarGundamX'': Both of Witz Su's Airmaster Gundams have plane-shaped flight modes, as the name would imply. Olba Frost's Gundam Ashtaron also has a mobile armor mode.
** ''Anime/MobileSuitGundamSEED'': A large number of them, to the point that most of them transform. The Strike Gundam (the one operated by the protagonist) uses {{Mecha Expansion Pack}}s. Orb's military force mainly consist of Murasames, mass-produced transforming mobile suits, in ''Anime/MobileSuitGundamSEEDDestiny''. There are other examples in ZAFT and the EA as well.
** ''Anime/MobileSuitGundam00'': The Flags (and their European counterpart the Enact) have robot mode and a vaguely airplane like mode, as do the Kyrios and Arios Gundams. The final episode of ''Gundam 00'' contains what has to be the best, albeit likely unintentional lampshading of this trope ever, when BigBad [[spoiler:Ribbons']] Mobile suit transforms from a Mobile Suit into . . . [[spoiler:a slightly different Mobile Suit]].
*** The Flags and Enacts are odd examples because rather than transforming mid-battle like pretty much every other example on this page, they have to be "converted" between forms while at an airbase. Graham Akre is the first pilot to attempt a mid-air transformation, and by the time of TheMovie, the Braves (successors to the Flags) are all capable of doing so.
** ''Anime/SDGundamForce'': Captain Gundam has a Gunvehicle mode.
** ''Anime/MobileSuitGundamAGE'': The Gundam AGE 1 has two MechaExpansionPack that actually replace the arms and legs. The AGE 2 fits the more traditional transformation meaning by transforming into a plane mode, in addition to using removable parts like the AGE 1. By the time the AGE 2 is constructed, it appears that the RedShirt mecha for the Earth faction can use similar designs to the AGE 1. The RedShirt mecha that accompany AGE 3 are the traditional plane[=/=]mech model. The UE [[spoiler: also known as [[HumanAllAlong Vagan]]]] has several mecha which can [[InstantAwesomeJustAddDragons transform into]] [[OurDragonsAreDifferent dragons]].
** ''Anime/MobileSuitGundamIronBloodedOrphans'': The Gundam Kimaris Trooper, piloted by Gaelio Bauduin, can transform into a centaur-like hover mode.
* A mild example, Sonic Divers from ''Anime/SkyGirls'' can transform between Glider Mode (read: jet mode) and Armor Mode (read: mobile suit mode). These transformations are more for functionality than visual, because of their aerial exoskeleton armor structure, Sonic Divers can't perform a flashy transformation without grinding their pilots into meatbag.
* The QT Arms in ''Anime/TheGirlWhoLeaptThroughSpace''. They start off as a spaceship with a circular set of rocket boosters on the back, but can transform into a sort of centaurian humanoid form utilizing the boosters as a set of legs.
* In ''Anime/VipersCreed'', the mechs can transform into a motorcyle-like form for added speed, but the catch is that they can't be too high from the roadway or they can't gain their energy through wireless power. Enemy mecha mooks on the other hand don't have this limitation.
* The Manga/RideBack vehicles from the anime of the same name can switch between a Segway-like standing mode where they have wheels instead of feet for better agility; and a bike like form equivalent to a human doing the splits-which has higher speed.
* Phoron of ''VisualNovel/ShinkyokuSoukaiPolyphonica'' has a bike that can transform into some sort of piano-based music center. Since MagicMusic is fundamental in the world of ''Polyphonica'', this is definitely a good thing.
* ''RinneNoLagrange'' has the Vox units, which transform from a plane into a mecha.
* In ''Anime/CodeGeass'', [[BoisterousBruiser Gino's]] Tristan can turn into a jet and back.
** Lelouch/Zero's Shinkirou could also transform into a Jet/Submarine "Fortress Mode". The MR-1 frames seem to be a mass-produced civilian variation of this, going from truck to mecha.
* In ''Anime/TengenToppaGurrenLagann'', The Arc-Gurren and Chouginga Dai Gurren are multi-kilometric spaceships that double as {{Meta Mecha}}s (the latter, apart of being a MetaMecha of the former, can ALSO become ''the Moon''.
** Most of the Four Generals seem to have multi-mode mecha. Adiane's Sayrune mecha can go from a WingedHumanoid shape with a talking vagina to a hulking scorpion monster. Guame's Gember can switch between a hulking ape-like mode and some kind of woodlouse thing, and Cytomander's Shuzack changes from a WingedHumanoid to a disembodied skull with wings and scythe-arms.
** The Kiyalunga combines this with MechaExpansionPack in that it can transform into a lance and shield that can then be wielded by the King Kittan to form the King Kittan Deluxe.
* Team Rocket in ''Anime/{{Pokemon}}'' has made several of these, including a recent one that goes from digger to piloted mech. They're [[MadeOfExplodium not as durable]] as most examples of the trope.
* ''Anime/ArgentoSoma'': The SARG robots can switch between being a plane and a robot.
* ''Anime/NekketsuSaikyoGosaurer'' has a bunch of mechs that go from being a ELEMENTARY SCHOOL to a bunch of robot dinosaurs.
* The titular characters from ''Anime/{{Karas}}'' can change into jets or tank-racecar hybrids. Their actual transformations are a bit cheaty, as they go through a portal and come out changed on the other side. In the end, though, it doesn't really matter due to RuleOfCool.
* ''Anime/GenesisClimberMospeada'' features two types: the MOSPEADA, [[CoolBike motorcycles]] that can turn into powered armor, and the Legioss, which are similar to the Valkyrie fighters from ''Anime/{{Macross}}''. This was one of Creator/KenichiSonada's first jobs in animation, and he liked the concept enough to reuse it for...
* The [[CoolBike Motoslaves]] that the Knight Sabers ride from ''Anime/BubblegumCrisis''. Transformed, they can either act as independent combat robots or as extended power suits to provide their riders with additional firepower and some aerial mobility.
* ''Anime/MazingerZ'' gets in on the action in ''Anime/ShinMazinger'' by having the titular mech turn into a ''giant fist.''
* The title mecha of ''Anime/NinjaSenshiTobikage''.
* ''Manga/FairyTail'': Jose Porla can transform his entire ''castle'' in a giant mecha.
* ''Anime/PanzerWorldGalient'': The titular HumongousMecha is capable of transforming into a red-and-white jet fighter.
* Beethes, aka Beethoven (yes, that [[Music/LudwigVanBeethoven Beethoven]]) from ''Anime/{{Classicaloid}}'' creates these from large, mostly mechanical objects with MagicMusic. This goes from RuleOfCool to RuleOfFunny when [[BalefulPolymorph he gets turned into a fish temporarily]] and makes a crab mecha out of an oven and kitchen equipment.
* In ''Anime/ID0'' the former racer Rick Ayer has a custom [[AMechByAnyOtherName I-Machine]] that is able to transform into a fast and manoeuvrable jet-like vehicle
* 1990s anime fandubbing house Seishun Shitemasu (guilty of, among other films, the ParodyFandub ''Ranma 1/3: Notes from the Closet'') included the phrase "It even turns into a giant robot!" as an inside joke catchphrase, a reference to its first project, the Gunbuster fandub ''Robotech III: Not Necessarily the Sentinels''.

[[folder:Comic Books]]
* While none of these appear in ''ComicBook/AmericanBornChinese'', the trope is discussed and deconstructed in a rather philosophical way. In an early scene, the child protagonist tells an old woman that he wants to be a ''[[Franchise/{{Transformers}} transformer]]'' when he grows up. After she gets a brief explanation of the concept, the woman uses it to illustrate a point to the kid: [[BeYourself anyone can become something they aren't, but have to sacrifice their soul to do so.]] This is the core theme of the whole book.
** Assuming you take the old woman literally, this means that every single example on this page has [[DealWithTheDevil had congress with the devil.]] Good to know!

* ''Fanfic/ACrownOfStars'': In this story Asuka has a red HumongousMecha capable to turn into a jet fighter with space-travelling capabilities.
* Theecat's totemen in ''Fanfic/TheKeysStandAlone: The Soft World''. They can shift into all kinds of useful forms, and can also combine to make more useful forms.

* In ''Film/{{Spaceballs}}'', the villains' Spaceball One flagship transforms into Mega-Maid, a giant {{Fembot}} equipped with a vacuum cleaner to suck up Druidia's atmosphere.
* The agents' cars in ''Film/MenInBlack'' can transform from a mundane car (an LTD in the [[Film/MenInBlack first film]], a Mercedes-Benz in the [[Film/MenInBlackII second]]) into a superpowered jet-propulsed car at the touch of a BigRedButton.
* In the ''Film/JamesBond'' film ''Film/TheSpyWhoLovedMe'', Bond's Lotus Esprit can also become a really fast submarine.
* ''Film/SkyCaptainAndTheWorldOfTomorrow'' (2004) had airplanes that could transform in mid-dive into submersibles. The hero doesn't bother pointing this out to the DamselScrappy who's in the cockpit with him, so she's rather annoyed.
* Centauri's car in ''Film/TheLastStarfighter'' took the angular wedge design of the [=DeLorean=], turned it UpToEleven, then made it a ''transforming'' FlyingCar and CoolStarship.
* The titular ''Film/{{Taxi}}'' deploys spoiler wings and gains about 500 hp at the touch of a button.
* In ''Film/{{Big}}'', a prototype toy transforms from a robot into a skyscraper, and Creator/TomHanks' character suggests that the robot transform into something more fun, like an insect or a [[EverythingsBetterWithDinosaurs dinosaur]].
* Downplayed in the ''Franchise/StarWars'' prequels with the Trade Federation "Vulture Droid." Although primarily used as a fighter, its "wings" can reconfigure into four legs. However, this is only seen in a couple of shots.

* OlderThanTelevision: In what may be the earliest example of this trope, there was "The Terror", a vehicle from Creator/JulesVerne's ''Literature/MasterOfTheWorld'' (1904) which could become an airplane, a submarine & some kind of tank/armoured car that could move so fast it could not be seen by the naked eye.
* Travis S. "Doc" Taylor used transforming mecha in his ''One Day on Mars'' series of Hard SciFi books. Marine issue Mechs had 3 modes: Fighter, Bot and a hybrid Eagle mode with talons hanging down. Army tanks would switch into 2 modes: Hovertank and Bot. Justified throughout the book as assisted by AI and made enemies worry about 3 different styles of attack, rather then one.

[[folder:Live-Action TV]]
* ''Series/AmbassadorMagma'', by Osamu Tezuka is the possible TropeMaker. The giant robot was capable of transforming into a rocket.
* Most seasons of ''Franchise/SuperSentai'' and ''Franchise/PowerRangers'' have at least one mecha that can both [[CombiningMecha combine]] and transform on its own.
** The Rescue Megazord from ''Series/PowerRangersTurbo'' and its counterpart VRV Robo from ''Series/GekisouSentaiCarranger'' is a CombiningMecha made of five Transforming Mecha.
** The Dinozords from the first season of ''Series/MightyMorphinPowerRangers'' combined into a tank which would then be transformed into the humanoid battle mode, often without ever firing a shot. There was an instance of it transforming back to tank mode to knock Goldar over before switching to battle mode again.
** One pre-''Power Rangers'' ''Sentai'', ''Series/DenshiSentaiDenziman'', had the Daidenzin, which could transform from the space shuttle-like [=DenziFighter=] into the {{Super Robot}}esque Daidenzin.
* Some of the ''Franchise/KamenRider'' series in the Heisei era have these, albeit in a smaller scale compared to its sister series Super Sentai. Examples include:
** ''Series/KamenRider555'' has Autobajin, a motorcycle that can transform into an autonomous human-sized robot which can assist the eponymous Rider in combat. [[TheRival Kamen Rider Kaixa]] has one that changes into a bipedal walker that specializes in the MacrossMissileMassacre trope.
** ''Series/KamenRiderGaim'' probably has one of the stranger examples of this trope, as the Riders are able to summon a giant transforming watermelon. It can transform to either a humanoid robot mode or a flight mode. And despite possessing one of the most ridiculous concepts for a Transforming Mecha, this series is known for being one of the darkest installments of the Kamen Rider franchise.
** In some Kamen Rider series, the heroes are able to utilize small robotic allies that usually disguise themselves by transforming into everyday objects. Examples are the Disk Animals in ''Series/KamenRiderHibiki'', the Candroids in ''Series/KamenRiderOOO'' and the Foodroids in ''Series/KamenRiderFourze''
* ''Series/KnightRider'' managed to include this in a couple ways. In the original series, the fourth season introduced both "C" mode (Convertible) and Super Pursuit Mode. C mode had the hardtop (with t-tops) somehow folding away behind to make a convertible out of KITT. SPM had various pointy bits and a rocket booster pop out of places to allow a huge speed boost. In the new pilot, KITT did something of the reverse - he was able to disguise himself as a more mundane, base model Mustang to avoid standing out quite so much. It's unknown at this time how much that particular transformation might impact performance, or what other transformations might be possible.
** In the series proper, KITT transforms into other Ford ProductPlacement Opportunities - er, I mean ''vehicle types'', for specialized situations, like an F-150 for off-road.
** KARR in the new series could transform from a Mustang like KITT into a very scary wheeled exosuit bristling with machine guns and missile launchers. In the original series as well as the new, KARR is voiced by Peter Cullen which makes this a very full circle ShoutOut to the man and [[WesternAnimation/TheTransformers one of his most famous roles]].

[[folder:Newspaper Comics]]
* A weird place for one of these...the old ''ComicStrip/{{Heathcliff}}'' cartoon ''WesternAnimation/HeathcliffAndTheCatillacCats''. The namesake car moves from car to boat to..um, house trailer, I guess.

[[folder:Tabletop Games]]
* ''TabletopGame/BattleTech'':
** The first edition featured Land-Air Mechs, which are Battlemechs that are able to transform into fighter craft. The originals were licensed designs based on the Macross Valkyrie Fighters above, though they later received new art original to ''[=BattleTech=]''. They also somewhat subvert the trope in that they're acknowledged as highly specialized and somewhat extravagant niche units, not really competitive with either pure 'Mechs or pure aerospace fighters in their respective roles and of course requiring pilots specifically cross-trained to handle them competently in ''all'' of their possible modes ('Mech, fighter, and depending on the design possibly [[MilitaryMashupMachine a hybrid "[=AirMech=]" configuration]]). The Succession Wars destroyed all but one of the factories that built these advanced mechs, making them all but impossible to keep running due to their LostTechnology, and their virtual extinction was a way for FASA to wring their hands of the [[ExecutiveMeddling messy lawsuit]] that these mechs and other licensed designs caused. Later editions limited them to the Tech level 3 rules, an optional ruleset for more realism and/or advanced technology.
** The Novels made mention of a variant developed by the Clans that had two pilots, one a [=MechWarrior=] one and the other an Fighter Pilot. Given how marginalised the Pilot bloodlines are in the Clans' eugenics programs, it resulted in a rocky working relationship as the best of times and both pilots fighting for control doomed the project.
** A number of other more recent Land-Air Mechs have popped up but none have reached full scale production and most were {{Flawed Prototype}}s at best. The Manei Domini produced three LAM models outfitted with ultra-light weight Clan technology, but outrageous costs and mediocre performance even with [[BrainComputerInterface augmented pilots]] made them a rarity. There was a brief attempt to make a ''flying'' SpiderTank in the Scorpion LAM, which failed to ever fly, and sat mothballed for close to 400 years; when rediscovered, the prototype was used to improve the ride quality in standard Scorpion quadmechs.
** It has to be mentioned that with the tabletop ruleset at the time of their introduction, [=LAMs=] were a pain to deal with. While they couldn't compete in either Mech or Fighter mode, the hybrid [=AirMech=] form was a nigh unhittable FragileSpeedster perfectly capable of taking down 'Mechs twice its weight, thanks to the insane to-hit modifiers their speed provided.
* The first chapter of ''Shards of the TabletopGame/{{Exalted}} Dream'' features a voidfighter design capable of converting from space fighter to warstrider form. The first prototype was known as the ''Scarlet Empress'', and is so far the only one to be piloted by a non-Solar.
* ''TabletopGame/{{Mekton}}'' has this, although it can get a bit pricey, especially when you have multiple forms.

* ''Franchise/{{Transformers}}'', obviously enough, and probably the most famous example in the west. The [[HigherTechSpecies higher capability]] is somewhat of a JustifiedTrope here, as some ''[[Really700YearsOld individual Transformers]]'' are [[TimeAbyss older than our whole species.]] Also notable for being [[RidiculouslyHumanRobots sentient]] rather than piloted (although half of the [[MerchandiseDriven original toys]] were repainted from Japanese toys that ''were'' supposedly piloted; the other half were to-scale objects like Penny Racers, radios, cassette players, and even handguns that transformed into robots).
** Worth noting is that a number of Transformers have more than two modes... In fact, there's a few with six, and one with ''ten''.
*** Later installments into the franchise would go on to show that transformation is not just present in the Transformers themselves, but can be found in almost ''every'' aspect of their society. Animal species, weapons, ships, ''buildings'' and in certain continuities ''their entire home planet'' of Cybertron (also [[PhysicalGod their god, Primus]]) are capable of transformation.
*** [[{{Franchise/TransformersAlignedUniverse}} The latest franchise]] ups the ante with Shifters, a Transformers sub-species that can transform into ''[[UpToEleven anything]]''! Understandably, they are [[ToylessToylineCharacter Toyless Toyline Characters]].
* The Baterra from ''Toys/{{Bionicle}}'' could shapeshift into anything, including trees and rocks, but avoided taking on the shapes of other people out of choice. [[ToylessToylineCharacter Sadly, they never appeared as sets]], [[WhatCouldHaveBeen although there were plans]]. Toys that ''did'' shapeshift were the Bohrok/Bohrok-Kal (into balls) and the Vahki (bipedal to quadruped).

[[folder:Video Games]]
* ''BulkSlash'' has you piloting a mech with an alternate jet form.
* ''GunMetal'' also has you piloting a mech with an alternate jet form.
* The UsefulNotes/NeoGeo BeatEmUp game ''Robo Army'' had a power-up that temporarily morphed the player character into a "Power Buggy", an invincible dunebuggy-type car that could barrel through hordes of enemies.
* The VideoGame/CustomRobo series has the Lightning Sky class of robos, which transform into fighter jets.
* The Interceptor car in the ''VideoGame/SpyHunter'' series, which can become a boat, a motorcycle, and sometimes a jet plane.
* A slew of original mecha in ''VideoGame/SuperRobotWars'', notably the Wildraubtier & R-1 (which are ''Macross'' or ''Gundam'' style planes-to-robots) and the Grungust series (which take cues more from ''Daitarn 3'').
** ''VideoGame/SuperRobotWars W'' contains a ''ship'', the Valstork, that transforms into the giant humanoid Valguard by [[CombiningMecha augmenting itself with its in-house mech Valhawk]], which itself has a plane Air Force mode and a humanoid Close Combat mode. When they [[CombiningMecha fuse with the Armstra ship]] into the even more massive Valzacard, the Arm Arcus transforms into a sword or a bow for it to wield.
** Aussenseiter and Dygenguar's combination attack, which transforms Aussenseiter into... a giant mecha horse. Which Dygenguar mounts. And then Dygenguar produces a sword no less than three times the length of itself. That's about when Trombe! is reaching its climax in the song, and you REALLY should have been running a long time ago.
** AND R-GUN! A Gundam-ish mecha transformed into a [[Main/{{BFG}} GUN?!]] Nice for you to get gunned-to-crap by [[CallingYourAttacks METAL! GENOCIDER!]]
*** To clarify, the R-Gun was intended to be a gun (as its name suggests) for the [[SuperRobot S!R!X!]] in the first place. Cue [[TheHero Ryuusei]] crying [[PunctuatedForEmphasis HYPER! TRONIUM! BUSTER! CANNON!]] for god's sake!
* The three main Agency vehicles in ''VideoGame/{{Crackdown}}'' all transform into bigger and badder forms as the player's Driving Skill rises. The Supercar turns into a machinegun-packing batmobile, the SUV turns into a monster-truck that can jump and drive up walls, and the Truck turns into... an even bigger and badder truck with a nitro-booster for maximum ramming power. No attempts are made to justify the blatantly impossible transformations. It happens because it's ''[[RuleOfCool cool]]''.
* In ''VideoGame/GunstarHeroes'' (both the original and the GBA remake), Green uses an ancient vehicle known as Seven Force. It has seven different variations. And you have to fight them all.
* ''VideoGame/ViewtifulJoe'' has the Six Machine, a transforming vehicle with six forms: A humongous mecha, a car, a jet, a submarine, a subterrine, and a cannon.
* In ''VideoGame/{{Xenosaga}}'', the E.S. Dinah could transform from a starship to a mecha and back; only about half the ship was used in the mecha form, leaving the rest to be used as a large energy weapon or just left floating in orbit. The E.S. Naphtali could also transform from a cruise mode to combat mode.
** Though the Dinah is more of a combiner, as its head is formed from a flying motorcycle that turns into a bed.
* In ''VideoGame/XenobladeChroniclesX'', Skells are capable of transforming into a vehicular mode, depending on their weight type. Light Types transform into nimble motorcycle-esque vehicles, Medium Types transform into slower but more stable four-wheelers, and Heavy Types employ tank treads.
* In ''VideoGame/CommandAndConquerRedAlert3'', the Empire's Tengus (anti-infantry mecha and anti-air jet) and [=VXs=] (anti-air mecha and anti-tank chopper). The Sea-Wing/Sky-Wings are more MilitaryMashupMachine.
** Dunno if it's intentional or not but the Mecha Tengu [[http://27.media.tumblr.com/NAJN8JTZ6jz9z4ocLT05SnPTo1_500.jpg stylistically resembles]] a [[{{Anime/SuperDimensionFortressMacross}} Variable Fighter in Gerwalk mode]]. Even the transformation and hovering movement is similar.
* In ''VideoGame/MischiefMakers'', each member of the Beastector has their own unique Transforming Mecha, which resembles the same animal as its pilot.
* ''VideoGame/RType'' TL series fighters transform into mecha when attached to force devices. They also use a different WaveMotionGun when transformed.
* The Terran Viking units in ''VideoGame/StarcraftII'' transform from a fighter with anti-air missiles to a mech with anti-ground machine guns. They're best used for raiding as the name suggests, fly up behind the enemy's defenses to their resources and transform to mow down their workers before their forces move back there.
** The fluff in the campaign mode describes a trait that Vikings have that's somewhat unique to this trope: The cockpit of the Viking transforms, too. Viking pilots have to be nimble enough to avoid the massive pieces of shifting machinery, and most rookie pilots end up losing a limb or two.
** Hellions/hellbats are a reverse example; originally a fast dune-buggy-like skirmish vehicle, the Hellion was retrofitted with the ability to transform in the game's first expansion, becoming a slower, but tougher close-combat mech.
* ''VideoGame/TheGuardianLegend'''s main character, a RobotGirl who takes a humanoid form during the dungeon crawling parts of the game, then switches to spaceship form for some VerticalScrollingShooter action.
* Mr. Heli Robo at the beginning of Stage 6 in ''VideoGame/{{Contra}}: Shattered Soldier''.
* Turbo Man in ''VideoGame/MegaMan7'', Ground Man in ''VideoGame/MegaManAndBass'', Galaxy Man in ''VideoGame/MegaMan9'', & Nitro Man in ''VideoGame/MegaMan10''; as well as Ride Boarski of ''VideoGame/MegaManX7''.
* ''VideoGame/LostPlanet: Extreme Condition'' has the [=GAB-25=] [[AMechByAnyOtherName Vital Suit]] that can change from being a [[SpiderTank quadrupedal mech]] to high speed DrillTank. It also has the [=GTF-13=] which can transform between MiniMecha and jet-propelled snowmobile modes.
* ''VideoGame/StarFox2'' gave the Arwings and two other spacecraft a walking mech form-convenient for fighting on planets and inside battleships. This feature would later be carried over (along with a transforming Landmaster) to ''VideoGame/StarFoxZero''.
** [[spoiler: General Pepper's Ace Custom flagship]] in ''VideoGame/StarFoxAssault'' however, is this, its battle form using its wings as melee weapons.
* The protagonist of ''VideoGame/{{Thexder}}'' is obviously inspired by ''Anime/SuperDimensionFortressMacross'', transforming from a bipedal robot into a jet fighter. In the sequel, it attacks with {{Roboteching}} missiles, too.
* In ''VideoGame/TwistedMetal Black'', Sweet Tooth's truck can transform into a humanoid robot.
* In ''VideoGame/SakuraWars: [[VideoGame/SakuraWarsSoLongMyLove So Long, My Love]]'', the [=STARs=] are capable of transforming between a traditional bipedal form and a jet-like flight mode.
* The Eidolons from ''VideoGame/FinalFantasyXIII'', surprisingly enough, turned out to be these.
* ''VideoGame/RaidouKuzunohaVsTheSoullessArmy'' comes with FinalBoss the Soulless God Yasoumagatsu and the earlier Soulless God Oumagatsu, monstruous battleship/[[Anime/NeonGenesisEvangelion Evangelion]] hybrids capable of easily switching between forms. The transformation scene is ''awesome''.
* Several ''VideoGame/RaySeries'' bosses, including ''Ray Storm'''s first boss, and Sem-Strut in ''Ray Crisis''.
* The Vic Viper from ''VideoGame/{{Gradius}}'' appears in transformable form in ''VideoGame/ZoneOfTheEnders''.
** Also from the second game is the mook frame, NARITA, preferring to use its entire body as a weapon and transforms to ram into enemies.
** Tyrant and Nebula from the first game also counts as this which they go into during their second phase.
** Jehuty itself has a similar transformation by spreading its arms and wings, straightens its legs and its cockpit...faces forward.
* [[spoiler:Yami]], from ''VideoGame/{{Okami}}'' as a SequentialBoss. The presence of a Mecha in a game set in Ancient Japan is justified by the implication that [[spoiler:Yami, as well as being the God of Darkness is the [[ScienceIsBad creator-god of technology]].]]
* VideoGame/{{Starhawk}}, the upcoming SpiritualSuccessor to VideoGame/{{Warhawk}} has these as the [[http://www.youtube.com/watch?v=i08a0o-xpfw&feature=player_detailpage#t=49s standard, flying vehicle]].
* ''C.O.R.'', a GameMod for ''VideoGame/UnrealTournament2004'', was team deathmatch with transforming mecha, and awesome.
* ''VideoGame/ShogoMobileArmorDivision'' is a rare case of a FirstPersonShooter with Transforming Mecha.
* In ''[[VideoGame/TheLegendofZeldaCDIGames Link: The Faces of Evil]]'', Militron after his first defeat turns into a flying tank-chariot thing with spikes all over him to escape. He is seen transforming back in a cutscene prior to his second encounter, and after he is defeated again, his armor falls off, revealing a feeble old man underneath.
** This is also true with Iron Knuckle from ''Zelda: The Wand of Gamelon'', who instead turns into a spiky jet-chariot thing to escape after his first defeat, and after he is defeated again, his armor cracks open, causing his heart to fall out.
* ''VideoGame/FutureCopLAPD'' has the x-1 alpha that transforms between a battle walker and a hover car.
* ''VideoGame/BattleEngineAquila'' has the battle engines, which can turn change between jet mode and walker mode. However, in flight mode the battle engine must divert its DeflectorShields to propulsion, and even then it can only remain airborne for relatively short periods. In a world flooded by GlobalWarming, the battle engine must make use of [[ImprovisedPlatform any land, debris, or enemy airship or watercraft]] to land on to recharge lest it lose power, fall into the water [[SuperDrowningSkills and start to flood]].
* ''VideoGame/KidIcarusUprising'' features the Great Sacred Treasure, which transforms into nearly half a dozen modes in the fight against [[spoiler:Hades.]]
* ''VideoGame/AnarchyReigns'' has Garuda, who transforms into a jet and can be ridden on by his teammates in co-op modes.
** Aswell as the [[MechaMook Gargoyles]], who resemble Garuda, except with [[CyberCyclops one eye]] and plasma arms.
* The UsefulNotes/PCEngine shmup ''Psychic Storm'' had four ships that could transform into huge bio-mechanical creatures.
* In ''VideoGame/PhantasyStarIII'', the cyborg Wren could transform into an aeroplane, jet scooter and submarine once the required parts are obtained. Unfortunately, the Wren in ''VideoGame/PhantasyStarIV'' no longer seems to have this ability.
* VideoGame/ArmoredCore features quite a few of these.
** The most famous example is the final boss of Master of Arena, Nineball Seraph which could often travel faster by converting into a bird-like mode. It's also insanely powerful and sturdy for a transforming mech and is decked out with Beam Spam
*** It also returned as a final boss in ACE: R if the player is on their 11th playthrough and it's been pumped with steroids now featuring Primal Armor from the [=PS3=]-era games, a cloaking mode, Attack Drones and a wave motion cannon in its chest. The best part? You get to take it out for a joyride in an unlockable mission.
** In Armored Core 3, there is a blue MT model possessing a walker and flight mode. Taking it out while in walker mode is a first priority since it unloads powerful beam shots.
** In Nexus, there is yet another transforming mech which appears to be a prototype for the Pulverizers in Last Raven.
* ''VideoGame/Kirby64TheCrystalShards'' features the HR-1, a towering robot that transforms into a rocket-mode for the second half of the battle and attacks using scissors.
** ''VideoGame/KirbyPlanetRobobot'' has the Robobot Armor. While it is capable of PowerCopying, one of them becomes an auto-scrolling jet, aswell as a super fast racecar.
* ''VideoGame/AirMech'', drawing obvious and loving inspiration from ''VideoGame/HerzogZwei'', has the player piloting a robot that transforms into some kind of aircraft to command a variety of drone units on the ground.
* VideoGame/MarioAndLuigiDreamTeam has the Giant Luigi opponents Earthwake and Robo Drilldigger. The former is a mecha made of buildings that can transform into a flying swarm of them and a gigantic hammer, the latter a robot made of drill pieces that can become a tank or a flying vehicle in order to use different attacks.
* The UsefulNotes/AtariJaguar launch title ''Cybermorph'' has the player control a spacecraft that shape-shifts into different forms based on how the player flies. The sequel, ''Battlemorph,'' expands the idea with submersible and subterranean modes.
* ''VideoGame/{{Vanquish}}'' has the Argus, which transforms between a SpiderTank and a humanoid robot; View Hounds, which transform from helicopter drones to ground robots that use the blades as swords; and the BIA, which transforms from a humanoid to a scorpion.
* In ''[[VideoGame/TimeCrisis Time Crisis 5]]'', [[spoiler: [[BigBad Robert]] [[RogueProtagonist Baxter]]]] has a robot that starts out as a ChickenWalker, but then becomes a giant robot that [[spoiler: Robert]] himself will pilot.
* ''VideoGame/ScrapMechanic'', a construction sandbox game, contains the Controller gadget, that allows the players to create their own transforming constructions. With the game's system of DesignItYourselfEquipment, there's practically no limit on what sort of vehicles the players will be able to create.
* ''VideoGame/{{Strikers 1945}}'' features bosses that appear to be UsefulNotes/WorldWarII-era war machines at first...before transforming into mecha that [[AnachronismStew could not have been possible with 1940's-era technology]].
* In ''VideoGame/{{Overwatch}}'', the character Bastion can transform from his bipedal robot form to a either stationary turret or a tank.
* ''VideoGame/WildArms2'' and ''VideoGame/WildArms3'' feature the Dragon Caliber, Lombardia. He's a living mechanical "dragon" who can transform into a jet, and becomes your GlobalAirship after defeating him. He even gets a Gundam-style launch sequence in his very first appearance.
* In ''Franchise/TheElderScrolls'' series, the [[OurDwarvesAreDifferent Dwemer]] crafted Numidium is a [[RealityWarper Reality Warping]] HumongousMecha prominent in the backstory, and then as a major plot point in ''[[VideoGame/TheElderScrollsIIDaggerfall Daggerfall]]''. [[TheConqueror Tiber Septim]] used it to complete his conquest of Tamriel, something he likely would not have been able to do without it. It was so massive and so powerful that merely ''activating it'' warped time and reality, [[TimeCrash right up to affecting even the ''God of Time'' himself]]. [[https://i.imgur.com/wULJ9.jpg Here is a size comparison]], with the tiny specks at the bottom being full-sized people. Numidium was ''usually'' anthropomorphic, but could apparently change its shape from time to time. Considering its reality-warping abilities and how it was [[AnthropomorphicPersonification walking exemplification of refutation]], it makes sense that Numidium would not necessarily stick to one discrete shape.

* In [[http://theoryofeverythingcomics.com/god/ God(tm)]] a [[http://theoryofeverythingcomics.com/god/01/GOD01_06a.htm cappuccino machine]] is stuck in guardian mode and a [[http://theoryofeverythingcomics.com/god/01/GOD01_19a.htm Mormon Robot]] transforms into a [[http://theoryofeverythingcomics.com/god/01/GOD01_21a.htm bicycle]].
* ''ComicStrip/ThePerryBibleFellowship'': Magnimus and Refridgeron. 1) http://pbfcomics.com/121/ 2)http://pbfcomics.com/156/
* In ''Webcomic/BobAndGeorge'', [[http://www.bobandgeorge.com/archives/001023c Treble. Merging with Bass in the process.]]

[[folder:Western Animation]]
* The ''Ghostbuggy'', or "GB", from ''WesternAnimation/FilmationsGhostbusters'' (No, [[Franchise/{{Ghostbusters}} not the]] [[WesternAnimation/TheRealGhostbusters famous ones]]); this could transform into an airplane, a hovercraft, a snowmobile, and other vehicles. "[[NewPowersAsThePlotDemands Did I mention, it also travels in time?]]"
