Not actually badass soldiers from the Alps (though it's a reasonable mistake to make), this is a combination [[VideoGameTropes Video Game Trope]] and ShapeShifting Trope. This describes a game in which the main character can shape-shift into multiple forms. Each form can be used to do something specific - a water-based one to swim, an earth-based one to be TheBigGuy, an air-based one for speed, etc. In some games these would be different characters, forming a party, but in this one it's all the same guy.

Outside of video games, this kind of hero is often headlining a MerchandiseDriven show - after all, more forms means more toys.

[[folder: Action Adventure ]]

* ''VideoGame/TheLegendOfZeldaMajorasMask'' - Link can turn into a Deku, Goron, or Zora, each of which have different abilities. [[spoiler:He can also turn into the Fierce Deity, but that's [[EleventhHourSuperpower reserved for boss battles only]].]]
* ''{{Killer 7}}'' is made up of 7 assassins in one body.
* In ''VideoGame/{{Aquaria}}'', Naija gains [[EnergyBall Energy]], [[CannibalismSuperPower Beast]], [[GreenThumb Nature]], [[FantasticLightSource Sun]], [[{{Animorphism}} Fish]], [[SoulPower Spirit]], and [[FusionDance Dual]] forms from her MagicMusic normal form.
* The protagonist of ''KameoElementsOfPower''.
* In ''VideoGame/CastlevaniaOrderOfEcclesia'' there are three glyphs that change Shanoa's form into a [[{{Catgirl}} cat-woman]], [[OurVampiresAreDifferent bat-woman]], and [[RobotBuddy little robot thing]].
** Years before, Alucard of ''VideoGame/CastlevaniaSymphonyOfTheNight'' could change into a fire-breathing bat, a wolf that can run through enemy or mist. The mist could even be upgraded to DeadlyGas.
** Rush Form in the Sorrow series if Soma Cruz had captured one of the creature's souls that can let him turn into one of them.
* ''Metal Mutant'' has the titular character able to transform on-the-fly into a humanoid cyborg, a dinosaur and a bulky tank-bot; each form is extremely specialized - several enemies can be beaten only with a specific one (for example, only the Dino's bite and tail fire can hit low critters).
* ''Project AlteredBeast'' for the [=PS2=] gave Luke 9 different forms each with their own powers and abilities, these forms include a {{Werewolf}}, Merman, {{Wendigo}}, Garuda, {{Minotaur}}, [[OurDragonsAreDifferent Dragon]], [[spoiler:{{Bear|sAreBadNews}}]], [[spoiler: UWH, aka, Alien]] and a [[spoiler:Weretiger]]
* This is the main gimmick of ''VideoGame/{{Trine}}''. You play as a fighter, an archer, and a mage, all [[SharingABody sharing the same body]].
* In ''VideoGame/{{Bayonetta}}'', the titular heroine and the antagonist Jeanne, can change into a panther, bat, or crow depending on attribute the situation calls for. According to notebooks found in the game, this was just an ability of all Umbran witches.
* Chomp of ''VideoGame/MonsterTale'' can "evolve" into different forms at will.
* The protagonist of ''Videogame/DeadHeadFred'' is a private eye who lost his original head, with his default state being a BrainInAJar. He can equip different heads, each with their own unique abilities.
[[/folder]]

[[folder:Fighting Game ]]
* In the GundamVsSeries, [[HumongousMecha mobile suits]] which use {{Mecha Expansion Pack}}s in their original anime are usually turned into Swiss Army Heroes as a means of representing their unique abilities. The [[Anime/MobileSuitVictoryGundam Victory 2]], [[Anime/MobileSuitGundamSEED Strike]], [[Anime/MobileSuitGundamSEEDDestiny Impulse]] and [[Anime/MobileSuitGundamAGE AGE-2]] Gundams can change freely, while the [[Anime/MobileSuitGundamAGE AGE-1]] can only change one way per spawn (it reverts to its base form when it respawns). The [[OriginalGeneration Extreme Gundam]] plays more traditionally, starting in a base form and tranforming into an upgraded form after filling a meter, but the each form is treated as a separate character and must be chosen before the match starts.
[[/folder]]

[[folder:MMORPG]]

* The Druid class in ''WorldOfWarcraft'' is essentially this. They can access different forms which give them abilities similar to another class (e.g. cat form gives the same combat style as a Rogue, bear gives them better armor so they can tank like a Warrior), act as transport (e.g. travel form, flight form and swimming form) or completely unique (e.g. tree form improves their healing).
* In ''VideoGame/EdenEternal'' the player can cycle through the game's 15 classes at any time:
** Warrior, Knight, and Templar (thankfully not [[KnightTemplar the insane kind]]), tanking.
** Thief, Martial Artist, and Blade Dancer, melee DPS.
** Hunter, Engineer, and Ranger, ranged DPS.
** Cleric, Bard, and Shaman, healing and buffing.
** Magician, Illusionist, and Warlock, magic DPS.

[[folder: Platform Game ]]

* ''SuperMarioBros'' - Namely when one of the bros or anyone else is using a TransformationTrinket in stock.
* ''DemonsCrest'' - Firebrand has about five or six different forms, which he can shift between at will.
* ''VideoGame/WonderBoyIIITheDragonsTrap'' allowed the hero to transform into a dragon, lion, mouse, etc. He had to find a room to do the transformation though.
* ''MegaManZX''. You gain the ability to transform into 6 different forms in the first game, and ''15'' different forms in the second. [[spoiler: Plus one secret form in each game.]]
* {{Kirby}} gains various powers depending on what enemy he swallows.
* ''KidChameleon'' gave you various [[HatOfPower masks or helmets]] to transform you into differently-superpowered characters.
* The third ''VideoGame/WizardsAndWarriors'' game allows Kuros to switch between Knight, Thief and Mage at will to suit the situation.

[[/folder]]

[[folder: Role Playing Game ]]

* ''ShadowHearts'', sort of - Yuri can turn into different demons but there are other party members as well.
* The sloth demon's Fade level in ''VideoGame/DragonAgeOrigins''.
* ''MysticArk'' contains a slight variant: while the hero(ine) never changes form, (s)he is joined by two spirits who can each be made to inhabit one of several wooden figurines, bringing them to life as various allies ([[FighterMageThief fighter, mage, cleric, ninja, etc.]]). You can move those spirits around pretty much anytime outside of battle.
* Deoxys from the ''{{Pokemon}}'' games has 4 different forms that can be changed depending on the game in the Advance generation, or using some meteorites in the DS games. The forms are a normal one that acts as JackOfAllStats, a GlassCannon attack form, a StoneWall Defense form and a FragileSpeedster form. Another Pokémon that can change forms is Rotom, each of these forms gives it increased stats compared to its base form (the five forms have the same stats), a different Elemental power, and as of Gen V, its Ghost typing is swapped out for one matching that of the appliance it's possessed.
* The protagonists of ''VideoGame/KingdomHeartsBirthBySleep'' can get spells that let them transform into different [[TheHeartless Unversed]] in the [[UpdatedRerelease Final Mix]] version of the game.
* Most of the ''VideoGame/MegaManBattleNetwork'' games starting with [=BN2=] allow [=MegaMan=] to change into different variants.
** [=BN2=] and [=BN3=] had Style Change, where [=MegaMan=]'s body changes color and a certain part of his body is changed to reflect that Style's element (Heat, Aqua, Elec, or Wood) and specialty. They have one particular attribute (an improved buster, greater defense, more chips per turn, being able to carry more Navi chips and being able to get V4 and V5 Navi chips, turning invisible with each charge shot, being able to change the field, or receiving random good or bag bugs at the start of the battle) combined with one of the four aformentioned elements. You could switch between 2 in [=BN2=] but could only carry 1 in [=BN3=].
** [=BN4=] and [=BN5=] had Double Soul, a combination of this trope and MegaManning, as they are obtained through defeating one of [=MegaMan=]'s allies in battle. [=MegaMan=]'s charge shot is changed and he gains certain other attributes, usually an elemental affinity. It is toggled in-battle instead of on the overworld by discarding a chip corresponding to that soul (i.e., a Wood chip in [=BN5=] Team Colonel gives you Tomahawk Soul), but they each have at least one con (Knight Soul's charge shot is only melee range, Magnet Soul is weak to Wood attacks, etc.) and last for 3 turns, which can be increased using Navi Customizer programs. [=BN5=] also had Chaos Unisons, activated by discarding a Dark Chip, where it's the same form with a different color scheme and your charge shot turns into the Dark Chip you discarded, without the bugs or HP penalty you'd get using it by itself. If you fire at the wrong time, however, you'll turn back to normal and [=MegaMan=] DS will attack you for [[ThirteenIsUnlucky 13]] seconds, and he's invincible during that time, and the time it takes the shot to fully charge increases with each success[[note]]If you pause at the right time, it becomes significantly easier to hit your mark[[/note]]. They also only lasted for 1 turn, period.
*** [=BN4=] and [=BN5=] also had Dark Soul, activated by using Dark Chips constantly. There are a few minor differences such as [=MegaMan=] becoming darker in appearance and his emotion window gaining a malicious expression, and a few major ones such as not being able to go into Full Synchro, the inability to use certain chips, and being able to use Evil Chips and DS Navi Chips. It isn't nearly as useful as Double Soul, as its drawbacks outweigh its benefits.
** [=BN5=] had two Crosses, Bass Cross and Solar ([[VideoGame/{{Boktai}} Django]]) Cross, though they're barely similar to [=BN6=]'s Crosses as they override [=MegaMan=]'s standard form similar to Styles, sans elemental affinity.
*** Bass Cross can be obtained on the Japanese version using a promotional e-Reader card or obtained in the overseas version via cheating. You can also obtain it on any version of ''Double Team DS'' on an original DS or DS Lite if you insert a copy of the GBA version that Bass SP has been beaten on. The abilities and colors of this form depend on which version of the game you're playing, Team Colonel's version being silver and Team [=ProtoMan=]'s version being gold.
*** Solar Cross can be obtained in ''Double Team DS'' simply by having a copy of ''Boktai 2: Solar Boy Django'' in the GBA slot. As a reference to the ''Boktai'' series' usage of solar power, there will be a sun on the upper right corner of the screen that powers up the player's attacks if you're jacked in from an area outdoors.
** [=BN6=] introduces the Cross System. In contrast to [=BN5=], Crosses here are mostly like Souls, except that they're activated through a submenu on the Custom Screen instead of discarding a chip and you go back to normal if hit by a element countering yours.
*** There is also Beast Out, the ability to tap into Gregar or Falzar's power, gaining a rapid-fire buster, instantly locking on to the closest enemy, the ability to charge non-dimming elementless chips to perform powerful slash attacks, and they can be combined with Crosses to become even stronger. Because of the massive power exhibited, using this ability leaves [=MegaMan=] exhausted (which is visibly reflected on his emotion window) and he has to go battles without using it for it to recharge, as it lasts for a maximum 3 turns. If you try to do it while the counter is at 0 you'll go into Beast Over, where [=MegaMan=] goes berserk and [[CastFromHitPoints rapidly loses health]] but also goes into autopilot similar to [=BN5=]'s [=DarkInvis=].
** The Japan-exclusive mobile phone game ''Rockman.EXE Legend of Network'' has Trans Arm, which is the same as Double Soul except it only affects your buster as the name implies and the rest of your body is simply recolored.
* Similarly, the ''VideoGame/MegaManStarForce'' games all have different transformations per each game.
** The original has Star Break, activated in battle using a special card. Depending on what version you're playing, you'll turn into Ice Pegasus, Fire Leo, or Green Dragon, each of which have a different charge shot and a Star Force Big Bang activated by countering an enemy's attack. You can obtain the Star Breaks of the other two versions by having a [=BrotherBand=] with people on those versions.
** [=SF2=] has Zerker, Saurian, and Ninja transformations which are similar to Star Break except they can be combined.
** [=SF3=] has Noise Change, which is pretty much the Cross System from [=BN6=] with the one-at-a-time limitation of [=BN3=]'s Styles. There are 6 per version, though there's also [[IneffectualLoner Rogue]] Noise in both versions, obtained by refraining from making any [=BrotherBands=] with other players.
*** Also the immensely powerful titular Black Ace and Red Joker forms.
* In [[AlternateContinuity each]] of the ''VideoGame/BreathOfFire'' games, Ryu can transform into a variety of different dragons, each with differing abilities.
* An example where it's not the PlayerCharacter: One of Many in ''VideoGame/NeverwinterNights2: Mask of the Betrayer'' can change classes at will between [[FighterMageThief barbarian, warlock, and rogue]].

[[folder: Rhythm Game ]]

* Pretty much the whole point of the Hero of ''VideoGame/{{Patapon}} 2'' and ''3'' is to be an extra unit of your class of choice. An extra unit with some pretty awesome trinkets, too...

[[/folder]]

!!Non-video game examples:

[[folder: Anime and Manga ]]

* ''GetterRobo'', with a land-based, sky-based, and water-based form.
* ''{{Betterman}}'' has this power.
* Tony Tony Chopper from ''OnePiece'' has, like all [[VoluntaryShapeshifting Zoan-type users]], three basic forms; however, by using his Rumble Ball (a medication he developed), he expands that number to seven: his reindeer form (fast), his human form (strong), his hybrid form (brainy: he can do an EnemyScan; this is also his usual form, unlike most Zoan users) as well as a form optimized for jumping, defense, striking, and using his antlers. There is yet another form he takes on if he OD's on the Rumble Balls, a [[DangerousForbiddenTechnique terrifying, giant monster]]. Finally, he claims to have developed more during the TimeSkip, but they have yet to be seen.
* ''Anime/ZoidsNewCentury'' features the main character's Giant Robot Liger getting three different sets of armor named [[GratuitousGerman Jäger, Schneider, and Panzer]], which greatly enhanced speed, maneuverability, and firepower, respectively.
* Negi Springfield of ''Manga/MahouSenseiNegima'' can go between forms of his [[BlackMagic Magia Erebia]] [[SuperMode Armationem]], his Agilitas Fulminis oriented more towards [[FragileSpeedster speed and mobility with less offense and defense]] while being more alike to his use of [[BlowYouAway wind]] and [[ShockAndAwe lightning]], the other - his Sim Fabricatus - with [[MightyGlacier greater strength and defense over a loss of speed]]. Of note is that [[KenAkamatsu The author]] likes to reference games and [=RPG=]s throughout the series (this being one of many), so this can be argued to count as a ShoutOut to the game form of this trope.

[[/folder]]

[[folder: Comics ]]

* Aaron Stack aka Machine Man has all sorts of handy devices.

[[/folder]]

[[folder: Literature ]]

* The titular characters in the ''Literature/{{Animorphs}}'' series are this in spades. By the end of the series, each of the main characters has an arsenal of close to fifty animal forms in a wide variety of different shapes and sizes, though each character has a main group of 4-5 forms that they use most frequently, like a favorite battle form (Rachel's grizzly bear, for example) or a favorite bird of prey form for aerial recon. Most books in the series has them acquiring a new animal form which has abilities that will be particularly useful on their next upcoming mission. For example, on a mission when they needed to retrieve [[MacGuffin a special item]] from a pitch-black room, they acquired a bat form and used its natural echo-location to safely navigate through the room.
* Frank Zhang of {{The Heroes of Olympus}} also shows shades of this. Becoming an eagle, grizzly bear, and an elephant to take on a giant. [[spoiler: Also, having encountered basilisks early in "The Son of Neptune" Iris, the goddess of the Rainbow informs him that having a weasel is the best way of taking down basilisks. Later in the book after he discovers his shapeshifting abilities he is seen tearing through basilisks in weasel form and the basilisks are slithering away from him in terror.]]

[[/folder]]

[[folder: Live-Action TV ]]

* There are many ''Franchise/KamenRider'' examples, where the hero can change into different forms that specialize in different weapons and/or fighting styles. ''Series/KamenRiderBlackRX'' started the idea for the franchise with his Robo Rider and Bio Rider forms, but ''Series/KamenRiderKuuga'' really got it going.
** Taken to ridiculous extremes in ''Series/KamenRiderDecade'', where the main character not only has access to his own powers but also the powers and forms of every previous main Kamen Rider of the Heisei era.
** After Decade, ''Series/KamenRiderDouble'' and ''Series/KamenRiderOOO'' let the heroes mix and match several aspects of their powers. Double had two halves with three variations each (plus three unique combos) for a total of 12, while OOO has three parts with five variations (plus a unique combo) for a grand total of '''126''' (not counting parts used in movies and promo materials, which drive the number up even further).
* Even Decade is overshadowed by the ''Series/KaizokuSentaiGokaiger'', who have access to ''all 34 previous SuperSentai teams'', for a total of nearly 200 powersets (though each individual Gokaiger usually only uses the member of each past team that matches up with their own color, while the SixthRanger uses only the 15 other Sixth Rangers).

[[/folder]]

[[folder: Web Comics ]]

* In ''Webcomic/ElGoonishShive'', Elliot and Grace both have forms with which they can fly magically. Grace's flying form also has claws that can slowdown an opponent's HealingFactor when she attacks with them.

[[/folder]]

[[folder: Western Animation ]]

* This trope is ''WesternAnimation/{{Ben 10}}'''s entire gimmick. The titular hero wears the [[ImportedAlienPhlebotinum Omnitrix]] capable of temporarily transforming him into a number of alien forms, each with it's own powers and weaknesses.
* From the same company is Rex of ''GeneratorRex'', who can change parts of his body into various weapons and tools as needed, [[spoiler: and was even born in Switzerland]].
* One episode of ''WesternAnimation/MenInBlack TheAnimatedSeries'' involves Agent J being given superpowers. It was supposed to make him a FlyingBrick but the source of the powers was replaced with a Swiss Army Knife. So Agent J turned into a literal Swiss Army Hero, his arms turning into the various tools on one of those knives.
* In the {{retool}}ed second season of the ''WesternAnimation/IronMan'' cartoon, Iron Man upgraded his armor so that it could shift into a different design for every situation (subterranean armor, underwater armor, stealth armor, "samurai" armor, etc.). Note that while the concept of such armors is nothing new as the comics did the same, this is a blatant case of how MerchandiseDriven this trope can be, as each form had its own toy.
