A Transformation Trinket is an object which is the source of your shapeshifting powers, or at least a focus for them. It is vitally necessary to have your transformation trinket on your person in order to [[PowerMakeover change into]] your SuperpoweredAlterEgo. They're common among {{Henshin Hero}}es, and are almost always activated ByThePowerOfGrayskull

They may take the form of and double as a MagicalAccessory. Belts and belt buckles are common, as are wristbands, jewelry, and, for more recent works, cellphones. Weapons and {{magic wand}}s/staves/etc. also sometimes double as Transformation Trinkets. Sometimes swipe-cards, keys or entry-codes are used in conjunction with the item.

Reliance on a Transformation Trinket can be an AchillesHeel: [[PhlebotinumBreakdown they are subject to theft, loss, and breakage]]. Clever villains may also discover how to jam them and [[BroughtDownToNormal block your transformation ability]]. If your powers are mystical in nature, your trinket might not work unless you have self-confidence or faith in the righteousness of your cause. Beware that chances are you ''will'' be in a dangerous situation where the trinket is just out of reach and you'll be frantically reaching for it saying "IfICanOnlyMove..." The exception is if the object is a ClingyMacGuffin.

They make lovely [[MerchandiseDriven merchandise]] for the kids... [[PeripheryDemographic of all ages]]. So buy one today!

Compare ClothesMakeTheSuperman and PowerUpFood. Tends to be a form of AmuletOfConcentratedAwesome.

''[[TropeCo/TransformationTrinket This item]] is available in the TropeCo catalog.''

!!Examples:

[[foldercontrol]]

[[folder:Anime and Manga]]
* ''AkazukinChacha'': a little unusual in that there were actually three Transformation Trinkets-- shared among the three leads-- which had to be combined for Chacha to transform.
* ''CutieHoney'' has her choker. In ''Cutey Honey Flash'', she has a matching ring, and in ''Cutie Honey: The Live'', her trinket is a pendant that turns into the classic choker when she transforms.
* ''Franchise/SailorMoon'': Usagi and Chibiusa used jeweled brooches, while the other Solar-System Senshi used wands. Usagi also had a Disguise Pen (which was used in the first two seasons of the [[Anime/SailorMoon anime]], but dropped after that). The Sailor Starlights used head-mounted microphones, and in [[Series/PrettyGuardianSailorMoon the live action series]], as well as their transformation items (now bracelets), the girls had cellphones which they could use to disguise themselves. Heck, at one point Sailor Moon even used ''the Holy Grail'' to become Super Sailor Moon... or at least something ''called'' that for a while, then officially named the Cálice.
* ''DevilHunterYohko'': finger rings.
* ''Anime/TekkamanBlade'' used small crystal "sculptures." After Blade's crystal is shattered, it's installed into a HumongousMecha.
* ''PrettySammy'': a baton.
* ''RoninWarriors'' used crystal marbles. This element wasn't added until around episode 20.
* ''[[LyricalNanoha Magical Girl Lyrical Nanoha]]'': the weapon ''itself'' transforms into a pendant, keychain, badge, card, or other item when not in use, and is activated to transform both itself and its user.
** Vivio's is a more traditional MagicalGirl Transformation Trinket, since it retains its form while changing Vivio to her [[OlderAlterEgo teenage Magical Girl form]]. Oh, and it's a [[BunniesForCuteness bunny plushie]].
* Avoided in the ''{{Guyver}}'' anime, where Sho Fukamachi grows telepathic transmitters on the back of his neck that summon the Guyver armor.
* ''{{Spider Riders}}'': had a wristband like device called a Manacle that was used not just for transformations, but also for keeping their GiantSpiders in HammerSpace.
* ''Anime/PrettyCure'': The first few continuities use cell phone-like items (which weren't actually operatable as cellphones) called Communes, in which their {{Weasel Mascot}}s lived. ''Anime/YesPrettyCure5'' uses the wrist-mounted Pinky Catch, then goes back to the cell phone (but without mascots inside), this time called Cure-Mo. On the other hand, ''Anime/FreshPrettyCure'' had a handheld kind of cellphone that resembled an eletronic notebook, ''HeartcatchPrettyCure'' has perfume bottles (pictured above), ''Anime/SuitePrettyCure'' has brooches, ''Anime/SmilePrettyCure'' has make-up compacts (complete with powder puffs which appear during the TransformationSequence), ''Anime/DokiDokiPrettyCure'' goes back to cellphones and ''Anime/HappinessChargePrettyCure'' has compact mirrors.
* In ''Manga/TokyoMewMew'', the girls didn't originally need transformation pendants, but they were added for the anime. Unlike how they are portrayed in the former page image, the pendants were only part of chokers ''while'' transformed, not before, when they were just carried around like a normal TransformationTrinket. Just for the record.
* The pearls in ''MermaidMelodyPichiPichiPitch'', stored in shell necklaces when not in use and implanted inside the girls' microphones when they transform.
* ''KaitouSaintTail'' used what appeared to be a pendant on a chain, but it's an incense holder.
* ''Anime/CorrectorYui'' had another wrist-mounted device.
* ''Anime/OjamajoDoremi'' uses the "taps", circular musical instruments which vaguely resemble tambourines. In the second season, they were replaced by similar-looking devices shaped like [[FlowerMotifs flowers]]. In the third season, they used circular wrist-mounted devices that were attached to rings. Finally, in the fourth season, they use the "Cologne Taps": perfume bottles which, like the ''HeartcatchPrettyCure'' example above, trigger the transformations with a couple of spritzes; it doesn't help that both series have the same character designer.
** And while we're at it, [[SixthRanger Hana-chan]] had a transformation device that resembled a compact and was activated through the power of the other girls.
* ''Anime/DemashitaPowerpuffGirlsZ'' has rings and belt buckles.
* In ''Manga/CardcaptorSakura'' it's the trinket ''itself'' that transforms, not the magic user. (Her own personal fangirl provides the costumes.)
** It is a key-like pendant that transforms into a wand, by the way
* ''Anime/ScienceNinjaTeamGatchaman'' has transmutation wristbands. They also tripled as communicators and tracking beacons.
* In ''MahouSenseiNegima'', anyone can form a contract with a mage to draw on their power. This contract produces a tarot card, which can be used, among other things, to summon a weapon (sometimes [[ImprobableWeaponUser extremely unusual]]) and a variety of user-defined costumes.
* ''PuniPuniPoemi'' uses a dead fish. It's [[GagSeries that kind of show]].
* In ''Manga/HimitsuNoAkkoChan'', the protagonist Akko uses a MagicMirror or compact to transform into anything she wishes.
* In ''{{Pretear}}'', the "trinkets" are actually people, the Knights of Leafe. Himeno merges ("prets") with one to transform into the various Pretear forms.
* ''HanaNoKoLunlun'' has a magic pin that can change her outfit to suit whatever task is at hand.
* ''PersiaTheMagicFairy'' uses a magic baton.
* ''MagicalStarMagicalEmi'' uses a magic bracelet.
* ''MagicalStageFancyLala'' uses a magic pen which she wears as a necklace. The pen is decorated with a small clock whose hands [[OlderAlterEgo spin forward]] whenever she transforms.
* ''FloralMagicianMaryBell'' uses a pink tambourine.
* In ''Manga/{{Bleach}}'', after the Soul Society Arc, Ichigo is given a pendant that ejects his {{shinigami}} soul from his body so he can fight monsters. It beats the hell out of his earlier TransformationTrinket, which is a glove Rukia wears while she ''punches him in the face''; and Kon, a modified soul inside a candy that displaces his own. Although Kon is still somewhat useful, because Ichigo's body is essentially dead when Ichigo leaves it.
** When Rukia is in the real world she uses her own mod soul called "Chappy", which has an irritatingly cute personality (this was what she apparently tried to obtain when Ichigo ended up with Kon).
* ''Franchise/{{Digimon}}'' has the various incarnations of the Digivice. Instead of transforming the user, however, Digivices transform the user's BondCreature partner (except in ''Tamers'' in the case of Bio-Merging, and in ''Frontier'' where there are no partners). Other {{Transformation Trinket}}s across the various canons, generally used in conjunction with the Digivice, include the [[Anime/DigimonAdventure crests]], [[Anime/DigimonAdventure02 Digimentals]], [[Anime/DigimonTamers TCG cards]] and [[Anime/DigimonFrontier legendary spirits]].
* In ''{{Mai-Otome}}'', the [[MagicalGirl Otome]] have [=GEMs=], which are magical earrings that run on AppliedPhlebotinum.
* Karin Kokubu from ''AiToYuukiNoPigGirlTondeBuurin'' (better known as Super Pig for some) uses a pink compact with to transform into the pig [[AnimalSuperheroes Justice Buurin]]. The compact stores a pig's snout which is called by the phrase [[ByThePowerOfGreyskull "BA BI BU BE BOorin!"]], the compact then opens and the snout comes out and attaches to her face in one of the oddest [[TransformationSequence transformation sequences]] in anime. It also apparently is a form of communication of a king of a planet of [[AlienAnimals alien pigs]]. This is definitely one of the [[WidgetSeries more interesting trinkets]].
* Guy Shishioh from ''GaoGaiGar'' could in fact be considered the trinket himself, as he does technically 1) As cyborg guy have the power batteries that make him go hyper mode integrated into his body, where as 2) Being Evoluder Guy, he literally becomes part of the machines he pilots.
* The pocket watch in ''ChronoCrusade'' could be considered to be a very untraditional TransformationTrinket. When Chrono opens the watch, it allows him to turn into his true form--but the watch is what ''keeps'' him looking like a young normally. It doesn't make him transform so much as it removes the seal on his powers.
* ''Anime/PrincessTutu'' has a pendant for the main character, Ahiru. However, it's not just so she can turn into Princess Tutu--it's also so she can turn into a ''girl''. [[FirstEpisodeSpoiler She's really a duck]].
** Not only that, but [[spoiler:it also turns out to be one of the pieces of [[DismantledMacGuffin Mytho's heart]], the feeling of hope]].
* [[SplitPersonality Moka]] from ''RosarioToVampire'' wears a [[CreepyCoolCrosses rosary]] around her neck that [[OnlyTheChosenMayWield only Tsukune can remove]]. When it's on, she's [[NiceGirl Outer Moka]]. When it's off, she's [[{{Badass}} Inner Moka]]. It's somewhat an inversion though, as the amulet acutally serves as more of a [[SealedEvilInACan suppressor]] as [[spoiler:Inner Moka is the real Moka and Outer Moka is not.]]
* ''Anime/YuGiOh'' has the [[AmuletofConcentratedAwesome Millennium Puzzle]] that allows the main character to transform into his SuperPoweredAlterEgo when in danger.
** The Millennium Ring also hosted an ancient egyptian spirit who could could take control of his descendant's body when wearing it. The third alter ego, Yami Marik completely averts this trend, though the normal Marik was able to go into the Millenium Ring, sharing a body with both Yami and Normal Bakura, but not able to physically manifest himself like the two spirits of the millennium items are.
* ''AnimalDetectivesKiruminzoo'' has the eponymous kirumin compacts for the main characters, while the animilians can transform at will.
* ''KamichamaKarin'' has magic rings that let people transform into [[GreekMythology Greek gods]].
* In DragonballZ Bulma makes Gohan one (a watch) so he can fight crime as [[LargeHam THE GREAT SAIYAMAN]]! Later on Videl gets one too.
* Used in the TV adaptation of SkullMan. Coupled with BodyHorror and NightmareFuel.
* Fine and Rein of ''Anime/FushigiboshiNoFutagoHime'' each have a Sunny Luce, a compact that allows them to use the power of [[TheForce The Prominence]]. They can also use it to call on their [[MagicWand Sunny Rod]] without being transformed.
* ''Anime/PuellaMagiMadokaMagica'': 'Soul Gems'. Kept as a ring most of the time, turned into a faberge egg looking thing when transforming or using magic untransformed, then becomes a PowerCrystal of some sort when transformed. [[spoiler: And the name is [[SoulJar quite literal]]]].
* Ai from ''LightNovel/DragonCrisis'' has a transformation trinket that has been imbedded inside her body that lets her transform into a pseudo-werewolf.
* The two sisters in ''MakerunaMakendo'' use an elephant wand and a striped baton.
* Lime's choker in ''JewelBEMHunterLime''.
* The Burst Hearts of ''PokemonReBurst''.
* The titular ribbon from ''HimechanNoRibon'', which has various handy powers, primarily allowing Himeko to turn herself into whoever she wants for one hour.
* ''ShugoChara'' has the Humpty Lock which Amu uses to fuse whichever Guardian Character's egg she needs for the situation to transform.
* In Episode 2 of ''HigurashiNoNakuKoroNi Kira'', Rika and Satoko were given staves that allowed them to transform into magical girls.
* In ''Anime/MiraculousLadybug'', Marinette has a pair of earrings that let her transform into a Ladybug-themed hero, while her love interest has a ring that does the same, but with a cat theme.
* ''Manga/ButsuZone'' - Sannju's armring.
* ''Anime/AoNoExorcist'' has the Kurikama, a demon-slaying sword. When drawn, [[AntiAntiChrist Rin]] becomes [[WreathedInFlames covered in blue fire]]. Unusually, he's actually extremely powerful even when it's sheathed.
* The titular heroine of ''Manga/NurseAngelRirikaSOS'' transforms into Nurse Angel using a magical hat which she [[ChekhovsGift got as a present]].
* ''Anime/GatchamanCrowds'' uses ''notebooks''. That triple as communication devices and a way of becoming InvisibleToNormals.
* In ''[[Manga/MagiLabyrinthOfMagic Magi - The Labyrinth of Magic]]'', mastery of a Metal Vessel allows it to be this, where the user [[FusionDance combines with]] the Djinn contained within to enter a SuperMode.

[[folder:ComicBooks]]
* Donald Blake's cane allows him to transform back to his true form, TheMightyThor, God of Thunder, and the cane itself transforms into the hammer Mjolnir.
* Likewise, Eric Masterson (AKA 'Thunderstrike') used his cane (AKA the enchanted mace 'Thunderstrike') to transform into his heroic alter ego (...''Thunderstrike').
* The H.E.R.O. dials in various incarnations of DCComics' ''Comicbook/{{Dial H for HERO}}''. The twist is the dial's user will turn into a ''different'' superhero each time, completely at random. And the dials seem to prefer [[WhatKindOfLamePowerIsHeartAnyway "unusual" powers]] to turning the wielder into yet another FlyingBrick.
* Darla Deering uses the "Thing Ring" mentioned in the WesternAnimation section to [[InstantArmor summon her Miss Thing]] armor in ''Comicbook/{{FF}}''.
* Dan Garrett, the first BlueBeetle, had the Scarab, which would transform him if he held it and spouted his magic word. Jaime Reyes, the third Blue Beetle, has the Scarab too... [[BodyHorror except it has attached itself to his spine]].
* Jack Ryder used the Molecular Transducer to turn into ComicBook/TheCreeper.
* Rather than transforming him, Rick Jones' Nega-Bands activated a hyperspace link that allowed him to switch places with [[{{Captain Mar-Vell}} Captain Marvel]], an alien hero who was stranded in the Negative Zone.
* The Fly, an ArchieComics hero, originally used a magic ring to transform into his superhuman form; when DCComics gained licensed use of the Archie superhero characters and rebooted them under the Impact Comics imprint, it was changed to a fly-in-amber amulet.
* From ''ComicBook/AstroCity'', Winged Victory's logo-shaped necklace serves this function in her civilian form.

[[folder:EasternAnimation]]
* In ''TheNewAdventuresOfHanuman'', Maruti uses a mace-shaped locket to turn into Hanuman.
[[/folder]]

[[folder: Fan Works]]
* George's ring in ''Fanfic/WithStringsAttached''. Also [[SoulJar contains part of his soul]]. And yes, he does lose it once.
[[/folder]]

[[folder:{{Film}}]]
* Inverted in ''Film/{{Wolf}}'', the amulet is supposed to ''prevent'' Will (JackNicholson) from transforming but at the end he discards it and becomes a full wolf.
* The titular mask from the 1994 comedy ''Film/TheMask'' (and its comic counterpart).
* In ''[[Film/IronMan Iron Man 2]]'' Tony has a suitcase which turns into and equips him with one of his Iron Man armour variations via something that is pretty much a TransformationSequence.
* In {{Disney}}'s ''The Shaggy Dog'', Dean Jones gets hold of an ancient talisman with an [[AltumVidetur ominous Latin]] inscription that turns him into the titular carpeted canine.
* Hank [=McCoy=] makes a serum that temporarily reverts him from "blue Beast" to "Nicholas Hoult" in ''Film/XMenDaysOfFuturePast''. [[spoiler:It comes to save him as a Sentinel is about to attack, as the serum not only disguises him but cloaks his X-gene as well.]]
[[/folder]]

[[folder:{{Literature}}]]
* The young adult novel ''The Monster's Ring'' by Creator/BruceCoville (part of the ''Literature/MagicShop'' series) is pretty much about ExactlyWhatItSaysOnTheTin...a ring that turns the wearer into a monster.
* In the ''Literature/RainbowMagic'' series, the 2 heroines of the series have been given lockets containing fairy dust, which turn them into fairies (by making them shrink and grow wings) when opened.
* ''Literature/InterstellarPig'' by William Sleator features this in the form of the equipment chosen by Barney that allows him to transform into any of the aliens he is battling; he becomes a carnivorous lichen.
* ''FlossieTeacakes'' has a magical coat that magically transforms her into an 18-year-old
* ''ComeOnOssie'', a book by the same author as ''Flossie'', main character Oswald uses his grandfather's medal to turn into an 18-year-old.
* The second book of ''Literature/TheDresdenFiles'', ''Literature/FoolMoon,'' has fur belts that turn FBI agents into rampaging werewolves.
* In the second book of the ''Literature/YoungWizards'' Series, Kit has to use a whalesark, or the essence of a deceased whale's nervous system, to transform into that whale.
[[/folder]]

[[folder:LiveActionTV]]
* ''Franchise/KamenRider'' series: for nearly all Riders, a belt. In the Heisei era, the belt generally works in conjunction with a second item, sometimes to access a SuperMode:
** [[Series/KamenRiderAmazon Amazon]] lampshades and subverts this. Amazon is always wearing a giant, rather goofy-looking belt buckle, but it's NOT his transformation trinket (his bracelet is).
** Averted with the {{deconstruction}} movie ''Film/ShinKamenRiderPrologue''; let's just say that its protagonist is closer to (a gorier version of) Comicbook/TheIncredibleHulk than a Kamen Rider...
** [[Series/KamenRiderKuuga Kuuga]]'s belt is effectively a one-time item; after his first transformation, it merged with his body (and even appears on X-rays!), emerging only when he needs it.
** ''Series/KamenRiderAgito'''s G3 had none. He was ''all'' tech, and had to physically don his battle suit (with a bit of automated finishing-up as parts lock into place; think IronMan, suitcase version.)
** The Riders of ''Series/KamenRiderRyuki'', ''Series/KamenRiderBlade'' and ''Series/KamenRiderDecade'' slot cards into their equipment to access their transformations, equipment, and special attacks.
*** In Ryuki, though, the cards don't activate transformation: the card ''holder'' generates the belt, and transformation is activated when the holder is placed in it.
** The Rider Gears in ''Series/KamenRiderFaiz'' fulfill two expectations at once, by using cellphones that slot into their belts.
** The Riders in ''Series/KamenRiderHibiki'' don't use belts but rather soundwave-activated items to transform.
** The various Riders in ''Series/KamenRiderKabuto'' use "Zecters" (robot insects or, in one case, arachnid) that usually mount on the belt buckle; [=TheBee=] and Kabutech Riders from TheMovie put theirs on wristbands, and Drake and Sasword use their weapons as their trinkets instead.
** [[Series/KamenRiderDenO Den-O]], who has a train motif, uses a smart-card akin to the [[http://en.wikipedia.org/wiki/Suica Suica system]], with the belt acting as the card reader.
** [[Series/KamenRiderKiva Kiva]]'s Transformation Trinket is Kivat, his kinda-sorta-robot bat sidekick. Kivat's bite causes the belt (and Fangire GameFace FacialMarkings) to appear, and Wataru places Kivat into place as the buckle to initiate transformation. The [[PoweredArmor IXA system]] requires the IXA Knuckle weapon, which links up with the belt that ''totally'' wasn't there before [[AWizardDidIt simply being in place]] when its user needs to trigger a transformation - no special effects, no sound, nothing, just having appeared between shots. The show generally acts as if the Knuckle is the only part that matters, as seen in episodes where you get this sequence: (1) User is hit hard enough to demorph. (2) IXA Knuckle goes flying. (3) Knuckle is picked up and used, activated by linking it with the belt that's now inexplicably around the new user's waist despite not having been there before. (The belt ''is'' manually attached in the suit's first few appearances though... but only the first few.)
** ''Series/KamenRiderDouble'' does things a little differently, as it is not the Drivers (belts) that do the transformations, but "Gaia Memory" modules. A Driver only protects the user from the [[PsychoSerum drug-like]] effects of the Gaia Memory. The [[MonsterOfTheWeek Monsters of the Fortnight]] uses Memories without Drivers, whereas major characters possess Drivers.
*** For Double himself, he's made up of two people through SharingABody. Shotaro, who forms the body, places the Double Driver buckle on his waist (only the buckle; the ''strap'' is generated from it. Several series' belts are this way.) This causes a copy of the whole apparatus to appear on Philip's waist. Both then insert a Memory for [[ElementalPowers element]] (Philip) and fighting style (Shotaro.) The Memory used by Philip is teleported from his buckle to Shotaro's, who then invokes the transformation. Philip's body passes out as his soul is now within the Double body. When the Fang Memory is used, the suit appears on Philip and it's Shotaro's body that's left uninhabited. When the [[SuperMode Xtreme Memory]] is used, it's a proper FusionDance with both bodies and minds merged into Double. Of course, the two-in-one thing creates some problems, since if they lose synch Double becomes paralyzed, and blocking the driver slot can ruin the transformation.
**** With the belt being manual for Shotaro and just appearing on Philip, ''both'' methods of belt summoning are featured in one rider.
** ''Series/KamenRiderOOO'' follows in the tradition of [[Series/KamenRiderDouble Double]], with the belt buckle (the OOO Driver) being a holder for the ''real'' Transformation Trinket, the Core Medals. Eiji then activates the medals by scanning them with a ''third'' device (OOO Scanner) that manifests on the belt whenever he puts on the buckle. As the RuleOfThree is a recurring motif, this isn't accidental.
** ''Series/KamenRiderFourze'' returns to the belt buckle (the Fourze Driver) being the ''real'' Transformation Trinket rather than the collectible items (the Astro Switches). After putting the buckle on, Gentaro flips the buckle's four front switches (not to be confused with the Astro Switches) on, initiating a 3-2-1 countdown after which he pulls a side lever to transform. The Astro Switches activate different weapons on the arms or legs, and certain special ones enable form changes. However, the [[MonsterOfTheWeek Zodiarts]] use Zodiarts Switches to transform, and the [[CoDragons Horoscopes]] have special unique Switches.
** ''Series/KamenRiderWizard'' has the [=WizarDriver=] belt, which unlike most belts is actually worn full-time: most of the time it's in a scaled-back form, having maybe a little larger belt buckle than can be found in real life but it's not too outrageous. Even in this form it can activate most of Wizard's [[RingOfPower Rings of Power]], as all he has to do is hold his ringed hand in front of it. When it's time to fight, ''then'' he can turn the thing to the full version that can activate his transformation rings as well. Which of them is the source of his power? [[spoiler: Actually, it's the Phantom monster inside him, whose powers he can draw because he was {{Badass}} enough to resist the "mental Xenomorph" process.]]
** ''Series/KamenRiderGaim'' has each Rider using a Sengoku Driver belt, which transforms them after placing a Lock Seed into the belt's empty slot. The belts initiate the transformation, but the actual power to transform comes from the Seeds.
** Subverted in ''Film/KamenRiderTheFirst'' and ''[[Film/KamenRiderTheNext The Next]]'', [[TheRemake remakes]] of [[Series/KamenRider the original series]] and ''Series/KamenRiderV3'' respectively. The "Hoppers" have their traditional Typhoon belts, but no actual transformation is involved - instead, they simply change into their costumes by removing the civilian clothing worn over them and donning their helmets. Sometimes it's even hard to tell when transformation ''takes place,'' as we cut from an un-suited Rider spinning the Typhoon's wheel to the suited Rider donning the helmet, with no 'ceremony' whatsoever. The ''entire suit'' is like the IXA belt: just in place as needed, no attention called to it, when did that get there?
** Interestingly, in some of the older series, posing and saying "henshin" causes the belt to appear in place and activate, without existing beforehand or actually being interacted with in any way. Sometimes it doesn't even appear to activate transformation - it just appears before the rest of the suit out of habit.
** A number of modern belts shout out the names of forms and attacks, sometimes with GratuitousEnglish. Some of the best belong to Faiz (which may have the sexiest voice of any TransformationTrinket), Decade (which has a trademark stutter when announcing finishers--"Final Attack Raido Hi-hi-hi-hibiki", for example), and Wizard (which sings on a loop while primed and waiting to activate a ring).
* ''Franchise/PowerRangers'' and ''Franchise/SuperSentai'' have gone through various Transformation Trinkets over the years. Wrist-worn devices are the most common, though cell phone morphers are being seen more often lately, but there are exceptions. The glove-style [=GekiChangers=] in ''[[Series/JukenSentaiGekiranger Gekiranger]]'' and the [[CoolShades sunglasses]]-styled Solar Morphers in ''[[Series/PowerRangersJungleFury Jungle Fury]]'', for example. The [[Series/KyoryuSentaiZyuranger Dino Buckler]] is the most iconic, being the original Power Morpher seen in ''Series/MightyMorphinPowerRangers'', and was belt-worn while transformed.
** Then there's the ''Series/PowerRangersSPD'' A-Squad. Their ''unmorphed uniforms'' are their morphers, apparently: Ranger-colorcoded energy flows from the colored portions of their uniforms to become the Ranger suits.
** A bit of EarlyInstallmentWeirdness: We actually don't see change devices until [[Series/DenshiSentaiDenziman the fourth series]]. In ''Series/HimitsuSentaiGoranger,'' the unmorphed Ranger jumps and yells "Go!" and a RepeatCut has them fly through the air again, but now suited (meaning we also don't get the first TransformationSequence in season one, either.) In ''Series/JAKQDengekitai,'' the heroes must enter "strengthening capsules", little booths that suit them up. There's a set on the base and a set on their plane. In ''Series/BattleFeverJ'' the heroes say "Fever!" and [[EverythingsBetterWithSpinning turn around once]], though the first time, they actually had to physically put on the suits. (This was most likely [[TheArtifact an artifact]] of the show's [[WhatCouldHaveBeen original intentions]] of being a Japanese adaptation of CaptainAmerica.)
** ''Series/KaizokuSentaiGokaiger'' follows in the tradition of ''Series/KamenRiderDouble'' and ''Series/KamenRiderOOO'' in that the cell phone morphers (the Mobirates) are just holders for the ''real'' transformation trinkets, the Ranger Keys: the [[BroughtDownToNormal dispersed]] essences of every single previous Ranger, materialized in the form of individual Yale keys. Indeed, when past Rangers gets their hands on their respective key, the reabsorbing of its power reverts it back into their own morpher.
*** ''Series/PowerRangersTurbo'' also had the keys be the real power source: the keys were put in a number of devices, and got all glowy to make other things happen (in the manner of several mystical power sources that reserve the right to occasionally do more than what they're normally used for.) However, it's easy to forget because they do this much less after TheMovie.
** Before them, ''Series/MightyMorphinPowerRangers''[='=] Power Coins did way more than morph the Rangers (which, under special circumstances, they could do without the morphers.)
** In ''Series/PowerRangersRPM,'' it's Engine Cells. A variety of them are placed in a variety of things, including the morphers (cell phones for [[PowerTrio the primary colors]], wrist-worn for [[ThreePlusTwo Green and Black]], weapons for [[SixthRanger Gold and Silver]]) and the Zords (to make them grow, because they're pocket-sized by default). However, they're much less of a plot point unto themselves than Ranger Keys or Turbo Keys, let alone Power Coins or [[Series/KamenRiderOOO Core Medals]].
** In ''Series/EngineSentaiGoOnger'', which is a more lighthearted series, the Engine ''Souls'' are more plot points. An Engine is an alien RobotBuddy that can only operate for so long at its proper HumongousMecha size under Earth's conditions, and after a time will revert to SleepModeSize, which takes the form of an Engine Cast (the toy-sized body) and an Engine Soul (''exactly'' [[OurSoulsAreDifferent what the name implies]].) When an Engine Soul is placed in a weapon, that allows the Engine to operate it from within. When placed in the morpher, the morpher creates a little cartoony hologram of the Engine. The Change Souls that power the morphers for transformation, however, aren't the soul of anything, and only do that.
** ''Series/ZyudenSentaiKyoryuger'', being a dinosaur series, decides that the most logical choice for the transformation trinkets is a large gun in which a battery is inserted. The guns, however, are more like the aforementioned belts belonging to Kamen Riders Double, OOO, and Wizard; the batteries, charged up with the user's bravery, are what cause the transformation. The exceptions are the SixthRanger, who was born before the existence of guns and uses a large wrist-worn crossbow-like device, and the first two {{Guest Star Party Member}}s, who are already dead and now manifest as spirits that can channel their bravery directly into their batteries.
** Kyoryuger's successor ToQger returns to the wrist devices for the main five. However, they're two-piece: a model of each Ranger's personal train car mecha is inserted into the ToQ Changer. Yes, they are interchangeable. Each train comes with a model to be used in the Changer to summon it, or in some cases use its power at small size. They're similar to the Beast Batteries of Kyoryuger.
* The ''Franchise/UltraSeries'' typically has the human host of each title character use an activator device to initiate the change.
** For the first one, Series/{{Ultraman}}, it was called a "Beta Capsule".
** Interestingly, [[Series/ReturnOfUltraman Ultraman Jack]] [[AvertedTrope averted]] this, transforming simply through an act of will.
** In the Ultra Series, the device is usually a handheld wand-thing.
* ''MadanSenkiRyukendo'' is another case of the weapon itself being the transformation item.
* On ''Series/TheMysticKnightsOfTirNaNog'', the Mystic Weapons are also the transformation trinkets.
* In ''SuperhumanSamuraiSyberSquad,'' the procedure was more involved than most cases: Sam had to bring up the Servo program on his computer, and then play a certain chord on his guitar. The process was automated in a wrist-worn device, so he ''can'' just push a button if he wants, but only seems to do this when he can't do the normal procedure from home.
** For the others, each says a code and does a pose. For Tanker, he tends to clap his drumsticks together, giving a jolt of electricity nobody but the viewer seems to see, when saying his phrase. This seems to be RuleOfCool or RuleOfFunny, because there is really ''no'' reason a totally-non-electronic pair of wooden drumsticks would (or could) have anything to do with the program.
* In the ''Series/StargateSG1'' episode "Foothold", the aliens use a device to appear as members of the SGC. Later in the episode, Sam Carter gets ahold of one of these devices and uses it to turn into her teammate Daniel Jackson.
* The Makai Knights of ''{{Garo}}'' transform by using their weapons to draw circles in the air.
* ''Series/TomicaHeroRescueFire'' combines this with CallingYourAttacks the device in this case is a ''megaphone'' they have to yell ''"Chakusou!"'' into. Fire-4 and Fire-5 use their weapons (swords with microphpones in the hilt) to transform.
* ''{{Series/Merlin}}'' had two villains with these in the episode "Gwaine". They used them to take the identities of knights they killed. They were crystals of some type, activated with a bit of the victim's blood.
* ''Series/OnceUponATime'' has an example similar to the ''Wolf'' one above; [[spoiler: Red Riding Hood's signature red cape is what keeps her genetic werewolf form condition at bay every full moon]]. She often forgoes it when she needs to transform as a distraction, however.
* ''Series/BIMASatriaGaruda'' has the red Power Stone for the hero, while apparently differently colored ones are used by villains.

* The [[OurDragonsAreDifferent Manaketes]] in the ''Franchise/FireEmblem'' series generally require an item called a dragonstone to transform into their true forms. As dragons, they generally have little trouble destroying the opposition, but once the stone runs out of uses and breaks, they're helpless [[TooAwesomeToUse unless you can somehow manage to find a new one]]. Story wise, Bantu, Fa, and Myrrh all get their stones stolen from them; the former simply requesting that you catch the thief responsible so he can help you (This happens on two occasions in two different games, no less), and the latter two needing to be rescued from the enemy.
** Remedied in ''VideoGame/FireEmblemAwakening'', where dragonstones are apparently common enough to be purchased from shops, despite the fact that manaketes have become a race of the legends. The same game introduces the [[HairRaisingHare Taguel]] race, who require beaststones to transform (Which likewise, can be purchased from shops). Both races can simply opt to rely on the strength of their human forms by taking up a normal class, as well.
* Link gets a few of those in several games.
** In ''VideoGame/TheLegendOfZeldaMajorasMask'', several masks are used to transform Link into other races, and the Fierce Deity Mask transforms him into... guess what.
** In ''VideoGame/TheLegendOfZeldaTwilightPrincess'', Zant curses Link into permanent Wolf form using a black crystal. After the curse is broken, Midna is able to use it to transform Link at any given time. Also, the first set of PlotCoupons essentially act like this for Midna.
* ''ViewtifulJoe'' has the V-Watches. Henshin a go-go, baby!
* ''KingdomHearts'' outright states that Sora's newer, black clothes are the TransformationTrinket for his Drive-Forms and the only thing that actually changes when he "drives". (Except for Anti-Form, where his whole appearance changes to that of a [[TheHeartless Heartless]]) They also help him absorb MP from the air, which is why the Magic-system in ''KingdomHearts II'' differs from that of the first part.
** More from ''KingdomHearts'', in ''BirthBySleep'' the pieces of armor that Terra, Aqua and Ven wear in their traveling clothes are used to activate the transformation into their full armor.
*** All together now: [[http://images3.wikia.nocookie.net/__cb20100206004944/kingdomhearts/images/f/fe/ArmorSummon.png IT'S MORPHIN' TIME!]]
* The biometals in ''MegaManZX'' and Geo's Transer/Star Carrier (With Omega-xis) in ''MegaManStarForce''. Most morphing adversaries in ''Star Force 2'' use Ancient Star Carriers, which are exactly the same only built directly with Murian technology.
** The anime version of ''MegaManBattleNetwork'' had Synchro Chips combined with the already existing [=PETs=]. The transformation only works in areas that has enabled Net Navis to manifest in the real world.
* Seems in every [[SuperMarioBros Mario Game]], there's a [[PowerUp new item]] that gives Mario and Luigi a new form in addition to new abilities.
** In ''SuperMarioBros'', it began with the famous Super Mushroom (doubles Mario's size and grants an extra HitPoint), the Fire Flower (shoot fireballs) and Super Star ([[InvincibilityPowerUp invincibility]]).
** ''[[VideoGame/SuperMarioBrosTheLostLevels Super Mario Bros.: The Lost Levels]]'' (the Japanese sequel) introduced the infamous PoisonMushroom, which inflicted damage instead of powering up Mario.
** ''VideoGame/SuperMarioBros3'' introduced the Super Leaf that turned Mario into Raccoon Mario (raccoon ears and a tail, limited flying/gliding abilities). Later in the game there's the Frog Suit (precision swimming), Tanooki Suit (Raccoon abilites plus transformation into a Tanooki statue that can crush virtually any enemy), and even the rare Hammer Suit (throw incredibly lethal hammers, the shell itself is impervious to fireballs). The GBA version of this added a "Feather" granting ''Cape Mario'', like in VideoGame/SuperMarioWorld.
** ''VideoGame/SuperMarioWorld'' retained the original three powerups, replacing the Leaf with the Feather for Cape Mario. A rare balloon powerup inflates Mario, allowing him to float in the air for a limited time.
** ''VideoGame/SuperMarioLand'' was like a handheld ''expy'' of the NES classic, with the orignal power ups, only the Fire Flower is replace by a flower that turns Mario to Superball Mario.
** ''VideoGame/SuperMarioLand2SixGoldenCoins'' continues the tradition with the original three power-ups and a new flying ability, this time a carrot that gives Mario bunny ears that make him fly for a bit. Also, because of the graphics for the black-white gameboy, Fire Mario had a feather on his head here. Also during the final battle with Wario, the villain goes through the three power ups (no star) in the fight.
** ''VideoGame/SuperMario64'': Ditch all the powerups for three hats: The blue cap make Mario invisible (and thus, invulnerable) and able to pass through certain walls; the Metal Cap turns Mario into an invincible heap of walking metal (complete with a remix of the Super Star music), and the red Wing Cap allows limited flight. ''Super Mario 64 DS'' however made invisibility exclusive to Luigi, metal exclusive to Wario, Yoshi gets to spit fireballs, and Mario can blow-up like in ''VideoGame/SuperMarioWorld'' or gets a feather and become Wing Mario.
** ''VideoGame/SuperMarioSunshine'' didn't have Mario change forms, but his talking-weapon of choice, FLUDD can switch modes with the right power up, to have Mario hover, jet up in the sky or to run with SuperSpeed.
** ''VideoGame/NewSuperMarioBros'' retains the Super Mushroom and the Fire Flower. There was also a temporary transformation with a Mega Mushroom, turning the user (even a boss used one!) into a giant unstoppable machine! There's also a new power-up, a blue shell that turns Mario or Luigi into Shell Mario (slide along the ground just like a turtle shell, knocking out everything in your path). There's also the Tiny Mushroom, turning Mario into a ''tiny'' OneHitPointWonder that can float through the air, fit into incredibly small pipes, and and [[WalkOnWater run across water]].
** There are seven forms this time in ''VideoGame/SuperMarioGalaxy'' (it even brought the Fire Flower to 3-D, if only temporarily). There's also an opposite called the Ice Flower that grants Ice Powers. The ''Super Star'' was replaced by a Rainbow Star wih an added speed boost, and this game has two flying abilities: a Red Star (exclusive to the HubLevel, sorry) turns Mario into Flying Mario, and a Bee Mushroom that gives him the hovering Bee Suit. There's even a Boo Mushroom that turns him into, (yep, you guessed it) Boo Mario who can float in the air and pass through certain walls. And finally there's the Spring Mushroom which turns Mario into Spring Mario and grants him super-jumps.
** ''VideoGame/NewSuperMarioBrosWii'' has an Ice Flower which grants different ice powers from the ''Galaxy'' version, a Propellor Mushroom for the new flying form (a jumpsuit with a propellor on the top), and a Penguin Suit (ice powers, slide into enemies, ''and'' improved swimming). There's also the Mini Mushroom from the DS version and the usual Super Mushroom, Fire Flower and Super Star.
** ''VideoGame/SuperMarioGalaxy2'' continues the tradition, bringing over almost all of the powerups from the first game, and introducing some new powerups: the Drill, which lets Mario burrow through dirt, the Cloud Flower, which allows Mario to create his own cloud platforms, and the Rock Mushroom, which turns Mario into a rolling rock to plow through enemies and smash into things. Yoshi also has his own powerups: a Dash Pepper that makes him run really fast for a time, a Blimp Fruit which allows Yoshi to float into the air for some time, and a Bulb Berry that lets Yoshi unveil hidden platforms (similar to the Matter Splatter levels of the first game, only Yoshi provides his own spotlight).
** ''VideoGame/SuperMario3DLand'' saw the return of Tanooki Mario minus the flight and statue capabilities ([[spoiler:in the normal world version anyway]]), the power-up based hit point system (thankfully Mario's default form is super this time) and the first ever appearance of an unlimited fire flower in a 3D Mario game. It also introduced the boomerang flower, [[ExactlyWhatItSaysOnTheTin which allows Mario to throw boomerangs]].
** ''VideoGame/NewSuperMarioBros2'' also brings back the Super Leaf from Super Mario Bros 3, this time granting the flight capabilities(and the return of the P-meter). There's even a Invincibility Leaf that turns Mario into the near invincible White Raccoon Mario if the player loses 5 lives in one world.
*** Speaking of new, the Gold Flower is introduced in this game, granting Mario and Luigi a more powerful fireball attack that creates shockwaves and can take out many enemies, giving the player more coins. This power lasts till you complete the level or get hit (demoting you to Fire Mario/Luigi in both cases).
** ''VideoGame/NewSuperMarioBrosU'' sees the return of the Super Mushroom, Fire Flower, Ice Flower, Mini Mushroom, [[spoiler: [[VideoGame/NewSuperMarioBrosWii Propeller Mushroom, and Penguin Suit]]]]. It also sees the introduction of the Super Acorn (which turns the recipient into a Flying Squirrel form, effectively a modified Raccoon Suit that looks like a circus costume) and the P-Acorn (which turns the recipient into P-, a powered-up Flying Squirrel form capable of infinite flight).
** ''VideoGame/SuperMario3DWorld'' sees the return of the ''3D Land''-style Tanooki form. It also is shown to feature a Cat Bell that gives the recipient a Cat Suit (no, not [[CatSuit that kind]]) that allows them to run up walls and tackle enemies, among other things.
* ''[[VideoGame/PokemonDiamondAndPearl Pokémon Platinum]]'' has two items for the purposes of transforming two Pokémon between their alternate forms. The Platinum Orb allows Giratina take on its Origin Forme in the real world, and the Gracidea flower allows Shaymin to take on its [[{{Flight}} Sky Forme]]. For the latter though, the transformation does not work at night and it can be canceled by Shaymin being [[StandardStatusEffects frozen.]]
** ''Videogame/PokemonXAndY'' introduces "Mega Evolutions", which allows a small selection of pokémon to take on their SuperMode forms during battle. The TransformationTrinket required to make it work comes in two parts: a Mega Stone to be held by the pokémon, with every pokémon that is able to mega evolve needing a specific stone, and a Mega Ring (or bracelet) to be held by the trainer, which is used to actually trigger the evolution.
* In addition to the usual MegaManning, some ''{{Kirby}}'' games have Copy Essences lying around that grant an ability when touched. In ''[[VideoGame/KirbySuperStar Milky Way Wishes]],'' this is the only way to use special abilities (they're permanent and can be switched at will though).
** Later games give Kirby a [[InfinityPlusOneSword souped-up special ability]], usually in the form of a wand or sword. The item bounces around the screen in place of an Ability Star when you let go of it, implying that it's the source of the ability instead of Kirby's copying power.
* In ''MuppetMonsterAdventure'' , the main character Robin the Frog can channel the powers of the monsters that his uncle Kermit and his friends have been transformed into with the help of special amulets. The Werebear amulet turns him into a werebear with the power to climb any climbable surface, the Muck Monster one turns him into a swamp creature with the power to swim underwater, the Nose-feratu one gives him flight and turns him into a bat, the [=KerMonster=] one turns him into a frankenstein-like creature with super strength, and the Bride of [=KerMonster=] one turns him into a Bride Of Frankenstein-like character with a superpowerful karate chop that can smash down doors.
* ''SilentHill3'' has the Princess Heart Transform Costume, which is activated by a key-shaped trinket.
* ''SonicTheHedgehog'', once you collected the required GreenRocks. The most famous being the seven [[MineralMacGuffin Chaos Emeralds]] to become [[SuperMode Super]], on in [[ActionGirl Blaze's]] case, the seven Sol Emeralds. The ''{{Sonic Storybook Series}}'' also bring us two new forms thanks to the seven [[SonicAndTheSecretRings World Rings]], and four [[SonicAndTheBlackKnight Sacred Swords]].
** Sonic Colors (and the Sonic Colors stages of Sonic Generations) had them in the form of the Wisps, small aliens who would allow Sonic to change into different forms for a brief period of time.
* The sequel for ''NiGHTSIntoDreams'' features persona masks that transform the Nightmaren in a Dolphin, Rocket and finally a Dragon.
* In ''VideoGame/{{Amagon}}'', Amagon only becomes able to transform into Megagon once the Mega-key is found.
* In ''VideoGame/TheLegendOfDragoon'', the main cast members possess colored crystal orbs called Dragoon Spirits that allow them to change into winged, armored warriors, complete with TransformationSequence.

* The accessories in ''VisualNovel/PrincessDebut'' let your main character don one of 20 different ballroom-ready costumes.
* In ''VisualNovel/LongLiveTheQueen'' you will need to go through quests to obtain your mother's magic crystal in order to officially become a magical girl and get the sparkly transformation sequence. After doing it once, though, the crystal becomes part of you, so you can't lose it.

[[folder:Web Comics]]
* Myan's collar in {{Cat Nine}} allows her to transform into a {{cat girl}} or various animals. Removing it turns her back to normal and removes other powers (like human speech) in the process.
* In ''SluggyFreelance'', Zoe's transformations into a camel are tied to a necklace given to her by Torg. She ''wishes'' she could conveniently lose the necklace somewhere, but after her first transformation it changed into a seemingly unremovable tattoo. Zoe doesn't mind the tattoo itself too much, but desperately wants to get rid of it so her friends can't turn her into a camel whenever they're feeling mischievious.
* Yuuki in ''Webcomic/SparklingGenerationValkyrieYuuki'' (a parody of MagicalGirl shows) transforms by use of a brooch. The brooch turns its user into a magical girl (technically, a Valkyrie) which is unfortunate for Yuuki, who was [[GenderBender originally a guy]].
** It's not so much a brooch as a magical jewel ''embedded in her chest''. Which does deal with the whole "broken, lost or stolen" thing - if any of those happened, Yuuki would be much more worried about bleeding to death than not having access to Valkyrie powers.
* Each member of the ''Webcomic/{{Panthera}}'' team has an amulet on a necklace "that contain[s] minerals that ease the transformation and help focus [their] elemental power" [[http://www.pantheracomic.com/?p=664]].
* In ''Webcomic/ElGoonishShive'', the Transformation Gun derived Cat Belt which has two buttons "Feline" and "Human".
* ''Webcomic/{{Darkbolt}}'' has the Demon Orbs which transforms the 'soul merged' humans into their demon armors. In one case the Phoenix Samurai changes due to an angel.
* In ''Webcomic/ToPreventWorldPeace'', every MagicalGirl has one. Focus items can be summoned at will (sorta like Sora's keyblade) and are necessary for transforming. If they ever break . . . it's not good.
* ''Webcomic/{{Homestuck}}'' has the rings and scepters of the Prospitian and Dersite monarchs, which apply the powers granted by the players' prototypings to the user. They don't work for humans though.

* Subverted in ''Literature/SailorNothing'', where Himei's TransformationTrinket is an enchanted version of a cheap plastic pendant she bought as a MagicalGirl fangirl. She then proceeds to muse:
-->Was the Holy Grail a 7-11 Big Gulp cup that someone spiffied up? The magic of it all was very dazzling, but I should have KNOWN something was wrong from the start. This wasn't how it [[YouWatchTooMuchX happened on TV]]. It wasn't this much of a hack job.
* The Dimensional Guardians from the web fiction serial ''Literature/DimensionHeroes'' use bands called Guardian Bands to transform into their battle armor. Before the protagonists discovered their powers, they were often thought of as pieces of jewelry.
* The ''ArcanaMagiUniverse'' features [[TransformationTrinket Transformation Trinkets]] in the form of jewelry; bracelets, rings, brooch, lockets, pendants. They all turn into weapons.
* In ''TheImpossibleMan'', Yuki has a TransformationTrinket in the form of a brooch that turns into her staff Tsubasa.
* [[WebVideo/TheRemarkableJourneyOfHigginsVonHiggings Higgins von Higgings]]' AmuletOfConcentratedAwesome.
-->''"The medallion!?"''
-->'''''"HOOOOOO!"'''''
* Linkara's Power Morpher and Zeonizer in ''WebVideo/AtopTheFourthWall''.
* Oingo uses a belt buckle for his disguises in ''WebVideo/VaguelyRecallingJoJo'', but it still has the flaw of giving him a shirt labelled Oingo.

[[folder:WesternAnimation]]
* In the ''Film/AceVentura'' episode "Howl of The Weremoose", Drew Talbit uses a moose talisman to change into his weremoose form. It is also revealed that smashing the talisman will break the curse and turn all the weremoose ghouls back to normal. Unfortunately, Ace doesn't read the fine print which says he who destroys the tailsman gets the antlers of the grand high moose himself.
* ''WesternAnimation/{{Ben 10}}'': Ben wears the Omnitrix on his wrist, and frequently calls it a [[GadgetWatches watch]] (even though it isn't).
** Subverted by Ben not originally knowing the device's true title, and the Nickname sticking.
** As the series went on he started calling it by the Omnitrix and stopped calling it "The Watch" altogether.
* One episode of ''WesternAnimation/DannyPhantom'' involved an amulet necklace that would turn the wearer into a dragon whenever they get angry.
* ''WesternAnimation/ElTigre: The Adventures of Manny Rivera'': a spinning belt buckle.
* In ''WesternAnimation/FredAndBarneyMeetTheThing'', The Thing from ''ComicBook/FantasticFour,'' instead of being permanently changed into a rocklike form, could go back and forth at will using a ring. The ''Franchise/FantasticFour'' guest appearance in ''{{Spider-Man The Animated Series}}'' saw him being given this ability by Doctor Doom, but, of course, [[StatusQuoIsGod he doesn't get to keep it for good]].
* ''WesternAnimation/HeManAndTheMastersOfTheUniverse1983'': He-Man had the Sword of Power.
* Jerrica Benton's Jem Star Earrings from ''[[WesternAnimation/{{Jem}} Jem and the Holograms]]''.
* In the Creator/HannaBarbera cartoon ''Mighty Mightor'', Tor had a magical club that he used to transform into the title character.
* In ''WesternAnimation/MyLittlePonyFriendshipIsMagic'', [[spoiler:The Elements of Harmony become the method by which Twilight becomes an [[WingedUnicorn Alicorn]].]]
** The six {{MacGuffin}}s obtained over the course of Season 4 become the keys for the Chest of Harmony, which transforms the Mane Six into [[SuperMode Rainbow Power mode]].
** In ''WesternAnimation/MyLittlePonyEquestriaGirlsRainbowRocks'', the Humane Six's MagicalGirl forms are activated by their [[ThePowerOfRock musical instruments]].
* ''WesternAnimation/PopPixie'' has the Magic Pops, which let the pixies transform into Pop Pixie form and get a major power boost.
* ''PrincessGwenevereAndTheJewelRiders'' used {{Power Crystal}}s.
* She-Ra from ''WesternAnimation/SheRaPrincessOfPower'' had the Sword of Protection, which was basically the Sword of Power with a few extra tricks and a jewel.
* ''WesternAnimation/SheZow'': [[TheEponymousShow SheZow]]'s Glamazon Power Ring, probably also the source of all of Guy's powers. Also counts as a ClingyMacGuffin.
* The Skysurfers from ''WesternAnimation/SkysurferStrikeForce'' use watches called Digitrans to transform themselves into their hero identities and their cars into flying surfboards.
* 1950s cartoon ''TomTerrific'' was able to morph into anything thanks to his magic funnel.
* ''WesternAnimation/{{WITCH}}'' had the Heart of Kandrakar/Candracar. The funny thing about it is that it had to be used for ''all five girls'' to transform and if one of them wasn't around when Will used it, she had to transform them then.
* In ''WesternAnimation/WinxClub'', the Mythix wands are required to unlock the Mythix transformation and are seen in the ''Main/TransformationSequence''.
* Lance and Ilana have watches that allow them to put on/transform into their Manus and Corus armor, respectively. Octus, already being a robot, doesn't need one of these, as he's able to merge all three of them into the ''{{Sym-Bionic Titan}}''.
* In order for the titular hero of DragonBooster to transform, he needs an Amulet (which holds a "key" of sorts) and Gauntlet. If he loses either one, he is stuck in his civilian form. It also requires that he shout a [[ByThePowerOfGreyskull Catchphrase]], but that's another trope entirely.
