[[caption-width-right:300:Good thing too, cause that armor would have been a bitch to put on.]]

Armor is nice, but it takes time to put on and take off, and can be kind of clunky if you have to go through narrow passageways depending on it's size, also getting out of it in a hurry if you need to go to the loo can be a real pain. Wouldn't it be much nicer if you could just create a suit out of thin air -- or, alternately, out of whatever raw-materials happen to be handy -- whenever you need one? Well, if you've got PsychicPowers, FunctionalMagic, or just some really nifty gadgets, you can!

Can range in size from a form-fitting suit to full-fledged HumongousMecha; if the former, it may or may not be PoweredArmor as well. It can also be used as a type of OneWingedAngel or SuperMode for the character in question. Note that we're not talking {{MacGyver|ing}}ed PoweredArmor here - rather, the armor is propelled and assembled by supernatural power of some sort, or {{teleport|ation}}ed in/assembled on the spot by {{Nanomachines}}. As a rule of thumb, if it takes more than a couple of minutes to assemble, it does not belong here.

CollapsibleHelmet is a more specific SubTrope where only the helmet appears/disappears.

Compare/contrast HenshinHero, ElementalArmor, ElementalBarrier, and WreathedInFlames.



[[folder:Anime & Manga]]
* Sensui from ''Manga/YuYuHakusho'' can use his Holy Light Energy to create two special sets of armor.
* In ''[[Anime/SCryed s-CRY-ed]]'', the protagonist's Alter power [[EvolvingWeapon develops like this]], initially covering just his arm, but later progressing to the right half of his torso, then full body armor.
** As well as [[spoiler: Ryuhou, Straight Cougar, and Martin Zigmarl]] - any Alloy-type Alter user does this to some extent, and it is implied by [[spoiler: Ryuhou when he reaches his fullest level of power]] that all Alter powers must become Alloy-type to unlock their maximum potential.
** Not so much covering as converting - the arm is actually transformed. (When he undergoes the whole body conversion, his legs are actually thinner than when untransformed, and in the original TransformationSequence we see his arm splitting into three segments.)
*** Hey you notice how he's always wearing a glove and long sleeves? On the few instances when he's not, you can see lines across his hand and arm. As the armor grows across him on varying levels, those lines appear where he's transformed. Turns out it's not just stylistic, [[FridgeHorror those are scars]] left from where [[BodyHorror his own body was torn apart by his Altar power and reconstructed into armor.]] It's to the point that, after unlocking his second level, his one eye only opens when manifesting the armor... [[EyeScream It was heavily damaged right before the first manifestation,]] and now it appears to potentially be ''part'' of the manifestation.
* The Barrier Jackets from ''Franchise/LyricalNanoha'' are conjured out of thin air and can take more beating than a main battle tank. Sure, they [[{{Stripperiffic}} don't look that way]] in [[DarkMagicalGirl some cases]] but [[LadyOfWar Signum]]'s, for example, both looks and functions just right. Presumably as a result of being able to be ready for battle in an instant, Bureau mages tend to wear their "dress" uniform virtually all the time outside combat when they're on duty.
* The Homunculus Greed from ''Manga/FullmetalAlchemist'' can use the carbon in his body to generate a {{Nigh Invulnerab|ility}}le second skin which he calls "The Ultimate Shield". Greed usually only armors up his arms (giving him claws in the process) and whatever specific body part is about to be hit, because [[TheFightingNarcissist full-body armor makes his face ugly]].
* Saber and Gilgamesh/Archer in ''VisualNovel/FateStayNight'' and ''VisualNovel/FateZero'' are both capable of this. Saber's is essentially made entirely of her magic energy. Gilgamesh presumably either does the same or simply pulls it through Gate of Babylon.
* The Mimetic Beasts of ''[[Anime/ShinkonGattaiGodannar Godannar]]'', who are small, alien organisms who create huge bodies for themselves out of available materials - whether that is rocks, people, or a space-shuttle…
* Referred to as Ex-Quipping in ''Manga/FairyTail.'' Instant Armor is Erza's specialty, and she sure has [[UnlimitedWardrobe a hell of a lot of armors]]. Lucy later develops a similar ability, allowing her to instantly change into clothing based on the Celestial Spirits that she summons and gain powers related to those spirits.
* The titular LightNovel/InfiniteStratos are [[PoweredArmor powered exoskeletons]] that teleport onto/around the user, summoned via wrist band (though it can be stored in pretty much any accessory; Cecilia's is stored in her earrings, Charlotte has a necklace, and Laura has it in a holster strapped to her thigh). The user has the option of just summoning the arm of their machine, used mostly as a HyperspaceMallet gag (and in one episode, Cecilia summons an AttackDrone to help with "[[LethalChef cooking]]". [[StuffBlowingUp It goes about as well as you'd expect]].
** Noteably, only the [[AceCustom 'personalized' IS-units]] have this function. The mass-produced RedShirt models are just run-off-the-mill PoweredArmor.
* The Mushi of ''LightNovel/MushiUta'' are mostly {{Mon}}s, but the one belonging to the main character Kakkouisa "fusion" type. In the beginning, it just merges with his arm and HandCannon to form an ArmCannon, but with time, it grows bigger and covers more - at the end, it's basically a suit of Chitinous armor that he can call up at any time. (Unfortunately, it sort of looks - and acts - like ''TabletopGame/CthulhuTech''...)
* The Robes from ''Anime/MaiOtome''. Once their receive authorization from their Masters an Otome can summon their Robe within the space of a few seconds. The Five Columns don't even have to worry about authorisation.
* The Bio-Booster Armour from ''Manga/{{Guyver}}''. The live-action movies had them erupt from bumps on the protagonists neck from some form of {{Hammerspace}}. The anime and manga just directly summons it from {{Hammerspace}} with a mini SphereOfDestruction that vaporizes any enemy foolish enough to get close to you while transforming.
* One of the contractors in the second season of ''Anime/DarkerThanBlack'' can instantly assemble improvised mecha around himself out of whatever materials happen to be nearby.
* ''Manga/MahouSenseiNegima''
** Jack Rakan can summon arm and leg armor via his artifact. And seemingly move it telekinetically, as [[spoiler:he has lost his arms and legs before that]].
** After becoming an Ariadne Knight, Yue can summon a set of full armor too.
* ''Manga/{{Bleach}}'': Sado's right arm can instantaneously transform into the "Right arm of the Giant", a supernatural arm that includes a vast shield-like form at the shoulder. Although it can attack with tremendous strength and power, it's actually a defensive ability, the shield acting to protect against attacks directed at him.
* Lots of characters can do this in ''Manga/ZatchBell''. The strongest armor spell seen in the manga can even [[AdaptiveArmor shapeshift]] and grants ''[[JetPack jets]]''.
* In ''Anime/HeroicAge'', the Silver Tribe can assemble their Full Hedron spaceships out of apparently nothing in under a minute. Couple this with their ability to survive at least a few minutes in vacuum and their ability to teleport, it means that blowing up a Hedron is a minor setback at most unless you manage to kill the Silver Tribesman himself (and considering the power of their personal Hedron Shields, this is easier said than done). All of this is accomplished through [[SufficientlyAdvancedAlien extremely advanced technology]] and PsychicPowers rather than anything explicitly supernatural, though.
* ''OnePiece''
** [[SmugSnake Mr. 3]] can create a suit of wax armor for himself that's harder than steel but melts when exposed to fire.
** [[ChefOfIron Wanze's]] ''Ra-Mens Formal Suit'' (a suit of armor made of '''ramen noodles''') borders on parodying this trope.
** Also, [[OldMaster Rayleigh]] describes Color of Armaments [[KiManipulation Haki]] as this, only [[InvisibleToNormals invisible]].
* ''Manga/SaintSeiya'' is all about this trope. It used to happen at least OncePerEpisode until the later sagas where they always had their armors on.
* One of the Black Phantom villains in ''Manga/ZettaiKarenChildren'' has the ability to spontaneously create HumongousMecha suits for himself, by using a combination of telekinesis and illusions. The suits are ACTUALLY just a number of handy vehicles and random bits of scenery suspended in the air and moved with TK, but his illusion-projection abilities makes it look -- and act -- like a classic mecha.
* Coco from ''Manga/{{Toriko}}'' has been shown to do this in a recent chapter. He can make an armor that looks similar to what the {{samurai}} wore with the poison in his body.
* Believe it or not this trope is invoked a few times in the ''Franchise/{{Metroid}}'' manga. That's right, Samus actually could hide her PoweredArmor in a very small place and summon it whenever she wanted.
* The mysterious HenshinHero, Brave, of ''LightNovel/DemonKingDaimao'', is empowered by a rather sleek suit of MagiTek PoweredArmor, which he can summon from another dimension with his TransformationTrinket wristband.
* Armor-type Over Souls in ''Manga/ShamanKing'' are these.
* In ''Anime/XMen'', Armor has a highly colorful version of this as her power.
* Jinchuriki gain this via their Chakra Cloaks in ''Manga/{{Naruto}}'', with Naruto taking it a step further with his [[GoldenSuperMode Biju Mode]] using Kurama's own tails as giant shields, all nine together are [[spoiler: strong enough to take a direct beam Bijudama from the fricken ''[[EldritchAbomination Ten-Tails]]'' without any damage]]. Uchiha such as Sasuke Uchiha, Madara Uchiha, and Itachi Uchiha gain instant armor with their [[DangerousForbiddenTechnique Mangekyo Sharingan]], called Susano'o. Finally the Hyuga can make a instant armor dome called Kaiten by charging chakra from every pour from their body and spinning at high speed.
* In ''Manga/AttackOnTitan'', [[spoiler:Titan transformation]] is essentially a particularly bizarre and extreme version of this, [[spoiler:conjuring a colossal organic 'suit' around yourself out of thin air]].
* In ''Manga/MyHeroAcademia'', both [[NiceGuy Eijirou Kirishima]] and [[ExtraOreDinary Tetsutetsu Tetsutetsu]] have this power.

[[folder:Comic Books]]
* ''ComicBook/XMen''
** ComicBook/{{Magneto}} of the Marvel Universe has been known to do this, from time to time, using his metal-control. Ranging from reconstructing his own broken armor from nearby junk, to forging himself into a gigantic steel titan! At one point, he disassembled his suit, sitting on a chair nearby, into sand-sized grains and re-formed it around himself, in seconds.
** [[Characters/XMen2000sMembers Armor]] can create magic armor around her body. (Well, DUH...) She would mockingly acknowledge the "duh" factor by wondering what if she called Wolverine, well, "Claw"... or "Stench"...
** Colossus, who can at anytime turn his entire body into organic steel. Likewise, ComicBook/EmmaFrost can transform into a diamond form.
* The latest Comicbook/BlueBeetle, Jaime Reyes, has this power thanks to the Scarab, an incredibly powerful piece of alien wartech that implanted itself in his body. [[{{Squick}} Just don't ask where the mass of the suit comes from.]] Dan Garrett, the first Blue Beetle, could also use the Scarab to call up a suit of armor (although since the Scarab was damaged at the time, it was nowhere near what it could do for Jaime).
* Comicbook/IronMan
** Iron Man's original armor took him a minute and a half to manually put on. Ever since his second suit, the time for the suiting-up process has been greatly diminished. For the Model 2 armor, it took Tony Stark only two seconds to slip on each limb into the suit. The suiting-up process of the Model 4 took "mere micro-seconds." These time measurements don't include the time it would take for Stark to put on the torso section of the armor, which he always carried on. Later suits, namely the Model 16, could even be summoned from a distance, and fly over him before enrobing him.
** The suiting-up process for the Extremis Armor makes it a form of Instant Armor. The armor plates are self propelled and can assemble around Tony in a matter of seconds, while the inner layers of the armor (the undersheath) are stored inside Tony's body. The suit-up was fast enough to fly over to Tony and enrobe him in the ''middle'' of an explosion.
** The [[https://en.wikipedia.org/wiki/Iron_Man%27s_armor#Bleeding_Edge_Armor Bleeding Edge Armour]] was stored in its entirety within Tony's body, which allowed for an extremely fast suit-up.
** The entirety of Stark's Model-Prime Armor could be stored within a watch, and enrobe him in a matter of milliseconds.
* For a time, Comicbook/{{Cyborg}} from the ''Comicbook/TeenTitans'' had a cloned body with a piece of shape-shifting alien tech implanted inside. This allowed him to switch between a human appearance and his classic, armored form at will.
* Miss Thing uses a [[TransformationTrinket pair of rings]] to instantaneously summon her armor in ''Comicbook/{{FF}}''.
* Towards the end of the ''Manga/RealityCheck'' semi-manga, Mr Bunwah is carrying one of these for the heroine.
* The Engineer (of ''[[Comicbook/TheAuthority Authority]]'' fame) replaced her blood with nine pints of polymorphic metal. She generally extrudes enough of it to make a gleaming silver bodysuit.
* Samantha of ''Comicbook/ClanDestine'' can generate "ectoplasmic" armor and swords which are impervious to anything short of Wolverine's claws, do not disappear until she actively dispels them, and also [[RuleOfCool look very cool]]. The one downside is that generating the armor inevitably [[ClothingDamage shreds her clothes]]. Each time Sam armors up, it looks a little different, with the suggestion that she's doing this on purpose- which makes sense; Sam's an artist in her day job.

[[folder:Fan Works]]
* In ''FanFic/AeonNatumEngel'', The Sword Лu-hvean'tahæn gives the Star Spawn High Priest the ability to manifest it.
* In ''Fanfic/KyonBigDamnHero'', Kyon's watch has a skin-suit armor function added, which also can be activated automatically to act as an emergency compress.
* In the ''Fanfic/PonyPOVSeries'', [[TheDragon General Hercules Beetle]], the Changeling's military leader, was genetically enhanced by Bio-alchemy to allow him to create an organic armor over his forelegs that can withstand nearly any attack. [[spoiler:His OneWingedAngel form is ''covered'' in it, rendering him NighInvulnerability, though it's quite taxing on his mana reserves.]]
* Luna and Celestia apparently have this in ''Fanfic/AHollowInEquestria'' as they're seen transforming their regalia into suits of armor.

[[folder:Films -- Live-Action]]
* In the 1989 ''{{Film/Batman}}'' a push of a button on the [[{{Thememobile}} Batmobile]] covers it in armor, which acts to protect it from bullets and acts to keep it from being stolen. This becomes a plot point in ''Film/BatmanReturns'', where as part of a plot to frame him and ruin his reputation, the Penguin has his people disable the armor so that they can plant a beacon into the vehicle that allows Penguin to control it remotely.
* In ''Film/BlackPanther2018'', Shuri makes T'Challa a new Panther suit that uses technology to keep it stored inside a necklace and will instantaneously suit him up when needed. She lampshades the notion of heroes fumbling around trying to put on an outfit as the reasoning for the upgrade.
* ''Film/IronMan''
** In [[Film/IronMan2 the second film]], Tony Stark has a suitcase that turns into a suit of armor, as a nod to the comics. However, it's more of an EmergencyWeapon, as it is significantly less powerful than the regular armor, and apparently only mounts the palm repulsors for weaponry. Still comes in very handy in a pinch.
** As part of Stark's continuing upgrades to his armor, this type shows up in ''Film/{{The Avengers|2012}}'' -- except that not only can it be stored in a cupboard, it is fully capable of ''flying itself to him'' and assembling itself around him autonomously. How long does this take, you might ask? [[DestinationDefenestration Less time than it takes to hit the ground falling off of Stark Tower]] ([[NotTheFallThatKillsYou barely]]).
** A prequel comic to the second film shows Tony trying different ways of making the armor come to him. One involves a missile that flies to him and buries its nose in the ground. That fails spectacularly, as the impact destroys the armor.
** By [[Film/IronMan3 the third film]], individual armor components now fly to Tony thanks to implants in his arms. Not only that, but he has pre-programmed gestures that can get the armor to assemble on someone he points at. He does this during the Mandarin's attack on his mansion to put the armor on Pepper (unfortunately, he never told her how to use the repulsors) and later to [[spoiler:force the BigBad into one of his armors and blow it up]].
** The Bleeding Edge suit in ''Film/AvengersInfinityWar'' represents even further advancement of the technology, as it is capable of unwrapping itself from a holder on Tony's chest roughly where his Arc Reactor used to be, ensuring that Tony is never without protection.
* ''Film/WonderWoman2017''
** In the said film, in the final battle scene, Ares created an armor reminiscent of his comic book appearance from metal and steel scrap lying around. He does this by telekinetically molding an armor around his body and melting eyeholes onto the helmet.

* In Creator/SimonRGreen's ''Literature/SecretHistories'' novels, nigh-invulnerable armor can emerge from a Drood's torc in an instant, or withdraw into it just as quickly.
* Implied in ''Literature/TheStormlightArchive'', as the full Knights can apparently manifest [[PoweredArmor Shardplate]] from thin air. None of the characters in the story proper have reached that level just yet, but in Dalinar's vision of the past, a Knight can be seen casually summoning and dismissing her helmet without it being seen off her head.
* In demon form, Amber of ''Literature/DemonRoad'' has retractable black scale armour.

[[folder:Live-Action TV]]
* The Makai Armour from ''Series/{{GARO}}''.
* A few ''Franchise/PowerRangers'' battleizers have this property.
* In the finale of ''Series/StarTrekVoyager'', Admiral Janeway travels back in time to give ''Voyager'' this upgrade, allowing a set of nigh-invulnerable ablative armor to be instantly created around the ship. Its frequently referred by fans as "''[[FanNickname Voyager's Batmobile Armour]]''".
** The only problem? The Borg have assimilated the technology (as well as OneHitKill torpedoes) and can now use it against everyone else.

* Valkyrie Frames in ''Roleplay/BattleActionHaremHighschoolSideCharacterQuest'' can be materialized and dematerialzied at will, so long as one is synched to a Valkyrie Core. Experienced users can summon the Frame instantly, while those who haven’t been synched as long take a few seconds.

[[folder:Tabletop Games]]
* One of the powers available to Celestial Circle sorcerers in the tabletop RPG ''TabletopGame/{{Exalted}}'', is to create a huge suit of magical armor, called a Warstrider, and then pilot it from the chest. Seen in action [[http://keychain.patternspider.net/archive/koc0166.html here]], in ''Webcomic/KeychainOfCreation'', an ''Exalted'' webcomic.
** There are a whole family of more general are more practical abilities, ranging from a humble kata to don your armor more swiftly to summoning and dismissing your suit of magical full-plate armor in an instant from anywhere in creation, or even just packing it away [[HammerSpace Elsewhere]].
* ''TabletopGame/DungeonsAndDragons''
** One 3.5 supplement has "called armor", allowing you to not only remove the lengthy times for putting it on, but leave it anywhere on the same plane. Psionic's allow you to pull armor (or a weapon) out of somewhere in existence.
** There's also Mage Armor, Shadow Shield, Ghostly Visage, and so on.
** The Fourth Edition supplement ''Adventurer's Vault'' provides "summoned" armor, which can be of any type, is basically put on the hard way ''once'', and then can be dismissed to and recalled from a "secure extradimensional location" at will, reappearing on the caller's person as though he or she had just put it on. It otherwise functions as plain old magical armor of its given type and bonus (minimum +2).
* ''TabletopGame/D20Future'' has the gadget "Digital Armor", where your armor is stored as a data pattern on a tiny piece of {{technobabble}} and can be summoned immediately from anywhere. You don't even need to don it. It's a PL9 gadget, though, so you are REALLY unlikely of ever seeing it. PL9 is practically CrystalSpiresAndTogas.
* The ''TabletopGame/{{Pathfinder}}'' ''Advanced Player's Guide'' contains a spell for Clerics and Paladins called "Instant Armor". The spell does ExactlyWhatItSaysOnTheTin.
** There's also the Wizard/Sorcerer and Magus spell "Swift Girding", though its function is to instantly equip the caster and/or willing allies with preexisting suits of armor rather than to create armor out of thin air.
* ''TabletopGame/{{Ponies and Parasprites}}'' has two sets of summoned armor.
** The Alchemy Brews ''Hide of Brass'' and ''[[TabletopGame/{{Exalted}} Celestially-Perfected Hide of Orichalcum]]'' provide the character damage reduction and immunity to extreme temperatures of any kind.
** Three of the Celestial Templates (the ''Phoenix Glories'', ''Aegis Mercurial'', and ''Sapphire Paramour'') grant the Chosen the ability to summon suits of armor from nothingness. The other five Celestial Templates instead summon some form of jewelry, though these gems still provide some manner of protection for the wearer.
* ''TabletopGame/YuGiOh'': By using their magical mirrors, the Necloth can don armor based on past Duel Terminal monsters. Avance gets the power of Unicore and Valkyrus. Shrit gets the power of Clausolas, Brionac and Trishula. Emilia gets the power of Gungnir. Exa gets the power of Catastor and Decisive Armor.
* The OGL supplement ''Chainmail Bikinis and Other Adventuring Gear for Beautiful People'' by EN Armory has the "quick-don armour", blessed by the Goddess of Sexual Escapades, which instantly jumps up and assembles itself on the owner upon command, in case their partner's spouse or parents come home unexpectedly...
* In the Three Galaxies setting for ''{{TabletopGame/Rifts}}'', Cosmo Knights can call on their "cosmic armor" in an instant. The appearance of the armor can vary according to individual taste, but it is always sleek, shiny, and able to withstand hits from starship-mounted weapons. Where it exists when not in use is never addressed.

[[folder:Video Games]]
* In the fighting game ''VideoGame/EvilZone'', special inspector Mikagami Sho used the command phrase 'Zerochaku' to summon his armored suit, becoming the HotBlooded hero DANZAIVER!
* The Sentinel Class' Tech Armor from ''VideoGame/MassEffect2'' can be deployed instantly and provides extra shielding. It also explodes to smack nearby enemies on their asses when it goes down.
* The highest power of the "Stone Armor" powerset in ''VideoGame/CityOfHeroes'' is "Granite Armor", which surrounds the hero completely with an impenetrable granite suit, making them nearly invulnerable, but also really slow. Its popularity has led to the general wisdom that Stone Tankers shouldn't waste too much time designing their costumes: nobody's gonna see them anyway.
* The "Golem Condiut" and "Aura Condiut" in ''VideoGame/{{inFamous}}'' are also examples of this. The first is a psychokinetic member of the Dustmen, who has pulled together a motley assembly of mainly-metallic trash, into a vaguely humanoid form. The toughest and most annoying unit in the game, hands down. The second, meanwhile, is a telekinetic member of the First Sons, who is basically projecting a gigantic [[SupernaturalIsPurple (and vaguely purple)]] spectral image of himself, stomping around and smashing stuff while his real body floats in the center.
* ''Franchise/TheElderScrolls'':
** The "Bound Armor" spell is available throughout most of the series and has this effect. It is a [[SummonMagic Conjuration]] spell which temporarily summons a set of Daedric armor for the caster. Flavor text various implies that the armor is either made out of pure [[{{Mana}} Magicka]] or is summoned from Oblivion itself (much like summoning actual [[OurDemonsAreDifferent lesser Daedra]]). It can quickly de-squishify your SquishyWizard.
** In ''[[VideoGame/TheElderScrollsIIIMorrowind Morrowind]]'', it is possible to enchant items with "constant effect" Bound Armor spells. With a high value item (meaning it can hold more powerful enchantments) and a powerful [[YourSoulIsMine Soul Gem]], it is possible to enchant the item to summon a permanent full set of Bound Armor (equivalent to full Daedric) as soon as you equip it. And the armor never needs repairs either, as if it gets damaged, you can simply remove the item and reequip it for a new set.
** In ''[[VideoGame/TheElderScrollsIVOblivion Oblivion]]'' the [[ApocalypseCult Mythic Dawn cultists]] that are responsible for killing the Emperor are able to conjure their custom weapons and armor from thin air by way of magic. The equipment immediately fades upon their death. (A clever setup, since it allows for {{Mooks}} who provide a real challenge, while leaving nothing worth looting behind.) The player can learn similar spells (which work the same way but conjure a different type of armor), and with the spell customization system, even design a spell that summons a full set of plate armor, sword, and shield with the press of a single button.
* One of the "Suit" power-ups in the PlatformGame ''VideoGame/{{Vexx}}'' works like this. The Rock Suit causes lava-hot stones to surround Vexx, making him invincible and letting him break through certain barriers. However, while covered in rock, he runs kind of awkwardly and he jumps like a chump. After a while, the rocks break off and he returns to normal.
* The main boss of the second dungeon in ''VideoGame/BeyondGoodAndEvil'' is a tiny, easily-damaged mini-{{Mook|s}} that uses [[BuffySpeak some kinda alien telepathy stuff]] to surround itself with metal machine parts and effectively become a giant, heroine-crushing psychic robot.
* One of the powers wielded by the shape-shifter Alex Mercer in ''VideoGame/{{Prototype}}'' is the ability to create a heavy, insectoid-looking armor out of available biomass. Completely covering, and can be sprung out in less than a second... it [[MightyGlacier slightly reduces his speed and agility but makes him]] ''[[MightyGlacier much]]'' [[MightyGlacier tougher]]. Or, if you prefer, you can deploy it through a several-seconds long TransformationSequence.
* ''Franchise/{{Metroid}}''
** Samus can put her armor on or off through a mental trigger. WordOfGod states that instead of willing it on or off, Samus must constantly concentrate just to maintain the armor. To take it off, she simply stops concentrating. Note this only started in ''Other M''. ''Metroid Prime 3'' and ''Fusion'' show that the armor stays on her when unconscious.
** In ''VideoGame/SuperSmashBros Brawl'', Zero Suit Samus can use a Smash Sphere to instantly assemble her PoweredArmor, damaging any nearby brawlers.
** ''VideoGame/MetroidOtherM'' gets into a downright {{Deconstruction}} of the "constant concentration" type of armor. Like when [[spoiler:Adam shoots her in the back so she doesn't fire at the ice-proof metroid]] and she slowly loses the suit out of physical shock and mental shock that [[spoiler:her Father Figure]] would do such a thing.
* ''Franchise/KingdomHearts''
** In ''VideoGame/KingdomHeartsBirthBySleep'', the main trio wear pieces of armor on their shoulders at all times, and can summon full suits of armor by touching the armor pieces.
** in ''VideoGame/KingdomHeartsDreamDropDistance'', [[spoiler:Ventus's armor protects Sora from the darkness when Sora's heart falls asleep. Unfortunately, the armor itself is corrupted (although Sora is fine)]].
** Two worlds in the series, [[{{Film/Tron}} Space Paranoids]] and [[Film/TronLegacy The Grid]], will automatically force the protagonists to wear armor upon entering. Justified, as they are both computer worlds based on the same franchise, and they are both {{Fisher Kingdom}}s in the films, as well.
* Producing this is the main function of Biometals in the ''VideoGame/MegaManZX'' series. ''VideoGame/MegaManX'' does something similar from ''X4'' onwards at the start of every stage.
* In ''VideoGame/SuperMario64'' and subsequently in ''Smash Brothers'', the metal cap/green block turns Mario/any smasher into a heavy armored version of themselves.
* In ''VideoGame/{{Diablo II}}'', 7 out of the 210 skills in the game are an example of this. Only the Druid, Necromancer, Assassin, and Sorceress can use any of them. All of them, except for the sorceress, who has access to 4 of the skills, can only use 1 of them. In ''VideoGame/DiabloIII'' the Wizard has three different types to choose from: ice, lightning or [[PureEnergy arcane]]. These are at least as offensive as they are defensive, either damaging or in some way weakening attackers.
* Similar to the Granite Form in ''VideoGame/CityOfHeroes'', ''VideoGame/DragonAgeII'' has the spell "Rock Armor" that covers the mage casting it in stone and make it easier to survive in close combat or against archers. There's even a potion that non-mages can use to simulate the spell, and since it has no requirements combined with a low stamina cost it's recommended that ''every'' mage take it. And it actually looks pretty cool to boot.
* The BigBad of ''VideoGame/MetalGearRisingRevengeance'' is souped up on nanomachines that harden his skin in response to trauma and make him immune to harm... [[HandWave Somehow]]. The reveal of this is played ''ever-so-slightly'' tongue in cheek.
* In ''VideoGame/DarkSoulsII'' getting to the level 1 in Dragon Remnants covenant grants you an item which, upon use, conjures a dragon-shaped helmet that lets you [[BreathWeapon breathe fire]], and level 2 reward item summons a full armor suit, helmet included. This Black Dragon armor has good defence-to-weight ratio but [[ClingyCostume can only be removed by death]].
* In ''Videogame/{{Warframe}}'', the Rhino [[PoweredArmor warframe]] can use his Void powers to give himself additional armor, in the form of a coating of silver (or [[BlingBlingBang gold for Rhino Prime]]) metal. The Chroma warframe can cast aside his outer pelt to act as a turret, [[ShedArmorGainSpeed losing armor but gaining speed in the process]], and the pelt can be recalled almost instantly. The Grineer councilor Vay Hek gets in on the fun with the ability to call in a HumongousMecha orbital insertion within seconds, which he [[MetaMecha plugs his augmented body]] into.
* One of the new powers in ''Videogame/DeusExMankindDivided'' is Titan Armor, which covers Adam in black polygonal armor that makes him {{Nigh Invulnerab|ility}}le.

[[folder:Web Comics]]
* ''Webcomic/TheCyantianChronicles'': Lifts are often stored in a HyperspaceArsenal and can be summoned at a moments notice. If they're not the size of a small house.
* ''Webcomic/{{Goblins}}'': The Axe of Prissan can create a suit of full plate for its wearer out of thin air.
* In ''Webcomic/FlakyPastry'', GadgeteerGenius Nitrine has a suit of Mega Man-ish powered armor that collapses into the form of a belt-buckle. Usually works as a SuperMode with a 30-second time-limit due to enormous power-consumption, but if she gets her hands on an infinite power source... watch out.
* In ''Webcomic/{{Pulse}}'', SuperheroSchool students Pulse and Bolt use their natural electrical powers to run flying PoweredArmor that can in a flash of light, collapse down into a ring they wear on their fingers.

[[folder:Web Original]]
* During Round 1 of WebOriginal/TheBookOfStoriesOCT, one of the entries featured an antagonist doing this with just his ''walker, tennis balls and all''.
* Alloy from ''Literature/TheDescendants'' does this using whatever metal happens to be available. He actually discovered his powers this way.
* In the Literature/WhateleyUniverse, Loophole and Jericho can both teleport their armor into place as long as they are pretty close to the armor and teleportation system. They both end up armorless when they're attacked in Boston in "Ayla and the Birthday Brawl". Then there's Iron Star, who can manifest a metal carapace armor around himself whenever he wants. Britomart can do the same with a Guyver-like armor, she just has real trouble getting it off: as a side effect she doesn't have a hair left on her body.
* Reginald Black's Ytarran Power Armor in ''WebVideo/TalesFromMyDDCampaign'' can be donned or removed in six seconds.
* ''WebAnimation/{{Dreamscape}}'': Anjren's PoweredArmor appears just by her touching a microchip to her chest.

* Occasionally used by Earthbenders in ''WesternAnimation/AvatarTheLastAirbender'', making rock-suits for themselves. During the Final Battle, Toph also demonstrates her mastery of Metalbending by making herself a metal-suit on the spot... Being Toph, she also made it a CrowningMomentOfFunny in the finale. "ShaveAndAHaircut, two '''[=BOOM!=]!'''"
* In ''WesternAnimation/JusticeLeague,'' Queen of the Royal Flush Gang could move and shape metal with her thoughts. At one point, she uses it to create a suit of armor and a sword out of casino tokens.
* More Iron Man, this time as a teenager. In ''WesternAnimation/IronManArmoredAdventures'', Tony Stark is 16 years old, and he's already figured out how to fold up the Iron Man Mk-1 armor into his backpack (equipped with anti-gravity servos so it doesn't weigh him down), with it unfolding and reforming in a matter of seconds.
* ''WesternAnimation/Ben10AlienForce'': Kevin's powers during seasons 1 and 2 allowed him to create a thin membrane around his body consisting of any matter he was touching. Come season 3, an unfortunate Omnitrix-related accident transformed his entire body into an amalgamation of several materials he'd used in the past two seasons, but this was eventually cured.
* The eponymous ''WesternAnimation/{{Centurions}}'' would have various sets of armor and weaponry beamed onto their person from a satellite as needed.
* In the ''WesternAnimation/TransformersPrime'' episode "Triangulation", Starscream chances upon a small (by Cybertronian standards) disc, which - when attached to his chest - spreads around his body, forming the titanic (and unstoppable) Apex Armor.
* In ''WesternAnimation/SpiderManUnlimited'' Peter Parker has a nano-machine ladden spidersuit that can be [[ImpossiblyCompactFolding folded up]] into watch form.
* One of the Shen Gong Wu on ''WesternAnimation/XiaolinShowdown'' is the Two-Ton Tunic. Inactive, it's just a simple shirt, but when called upon, becomes solid metal.
* The Amulet of Merlin from ''WesternAnimation/{{Trollhunters}}'' allows the Trollhunter to summon armor made of solid, silvery, metallic daylight - complete with the Sword of Daylight - onto their bodies instantaneously.
