Transformation Trinket
aka: Transformation Trinkets

Magie Bleu. Brand X parfum extraordinaire.

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 change into your Superpowered Alter Ego. They're common among Henshin Heroes and Magical Girls, and are almost always activated By the Power of Grayskull!.

They may take the form of and double as a Magical Accessory. Belts and belt buckles are common, as are wristbands, jewelry, and, since the Turn of the Millennium, cellphones. Weapons and magic wands/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 Achilles' Heel: they are subject to theft, loss, and breakage. Clever villains may also discover how to jam them and 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 "If I Can Only Move..." The exception is if the object is a Clingy MacGuffin.

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

Compare Clothes Make the Superman and Power-Up Food. Tends to be a form of Amulet of Concentrated Awesome.

This item is available in the Trope Co. catalog.

    Anime and Manga 
  • Akazukin Chacha: 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.
  • Cutey Honey 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.
  • Sailor Moon: 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, but dropped after that). The Sailor Starlights used head-mounted microphones, and in 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.
  • Devil Hunter Yohko: finger rings.
  • Tekkaman Blade used small crystal "sculptures." After Blade's crystal is shattered, it's installed into a Humongous Mecha.
  • Pretty Sammy: a baton.
  • Ronin Warriors used crystal marbles. This element wasn't added until around episode 20.
  • 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.
  • 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 Giant Spiders in Hammer Space.
  • Pretty Cure: The first few continuities use cell phone-like items (which weren't actually operatable as cellphones) called Communes, in which their Weasel Mascots lived. Yes! Pretty Cure 5 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, Fresh Pretty Cure! had a handheld kind of cellphone that resembled an electronic notebook, HeartCatch Pretty Cure! has perfume bottles (pictured above), Suite Pretty Cure ♪ has brooches, Smile Pretty Cure! has make-up compacts (complete with powder puffs which appear during the Transformation Sequence), Doki Doki Pretty Cure goes back to cellphones (which are the mascots), Happiness Charge Pretty Cure has compact mirrors, and Go! Princess Pretty Cure goes back to perfume bottles.
  • In Tokyo Mew Mew, 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 Transformation Trinket. Just for the record.
  • The pearls in Mermaid Melody Pichi Pichi Pitch, stored in shell necklaces when not in use and implanted inside the girls' microphones when they transform.
  • Kaitou Saint Tail used what appeared to be a pendant on a chain, but it's an incense holder.
  • Corrector Yui had another wrist-mounted device.
  • Ojamajo Doremi uses the "taps", circular musical instruments which vaguely resemble tambourines. In the second season, they were replaced by similar-looking devices shaped like 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 HeartCatch Pretty Cure! 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, Hana-chan had a transformation device that resembled a compact and was activated through the power of the other girls.
  • Demashita! Powerpuff Girls Z has rings and belt buckles.
  • In Cardcaptor Sakura 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
  • Science Ninja Team Gatchaman has transmutation wristbands. They also tripled as communicators and tracking beacons.
  • In Mahou Sensei Negima!, 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 extremely unusual) and a variety of user-defined costumes.
  • Puni Puni Poemi uses a dead fish. It's that kind of show.
  • In Himitsu no Akko-chan, the protagonist Akko uses a Magic Mirror or compact to transform into anything she wishes.
  • In Prétear, the "trinkets" are actually people, the Knights of Leafe. Himeno merges ("prets") with one to transform into the various Pretear forms.
  • Hana no Ko Lunlun has a magic pin that can change her outfit to suit whatever task is at hand.
  • Persia, the Magic Fairy uses a magic baton.
  • Magical Star Magical Emi uses a magic bracelet.
  • Magical Stage Fancy Lala: Lala uses a magic pen which she wears as a necklace. The pen is decorated with a small clock whose hands spin forward whenever she transforms.
  • Floral Magician Mary Bell uses a pink tambourine.
  • In 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 Transformation Trinket, 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).
  • Digimon has the various incarnations of the Digivice. Instead of transforming the user, however, Digivices transform the user's Bond Creature partner (except in Tamers in the case of Bio-Merging, and in Frontier where there are no partners). Other Transformation Trinkets across the various canons, generally used in conjunction with the Digivice, include the crests, Digimentals, TCG cards and legendary spirits.
  • In Mai-Otome, the Otome have GEMs, which are magical earrings that run on Applied Phlebotinum.
  • Karin Kokubu from Ai to Yuuki no Pig Girl Tonde Buurin (better known as Super Pig for some) uses a pink compact with to transform into the pig Justice Buurin. The compact stores a pig's snout which is called by the phrase "BA BI BU BE BOorin!", the compact then opens and the snout comes out and attaches to her face in one of the oddest transformation sequences in anime. It also apparently is a form of communication of a king of a planet of alien pigs. This is definitely one of the 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 Chrono Crusade could be considered to be a very untraditional Transformation Trinket. 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.
  • Princess Tutu 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. She's really a duck.
    • Not only that, but it also turns out to be one of the pieces of Mytho's heart, the feeling of hope.
  • Moka from Rosario To Vampire wears a rosary around her neck that only Tsukune can remove. When it's on, she's Outer Moka. When it's off, she's Inner Moka. It's somewhat an inversion though, as the amulet acutally serves as more of a suppressor as Inner Moka is the real Moka and Outer Moka is not.
  • Yu-Gi-Oh! has the Millennium Puzzle that allows the main character to transform into his Super-Powered Alter Ego 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.
  • Animal Detectives Kiruminzoo has the eponymous kirumin compacts for the main characters, while the animilians can transform at will.
  • Kamichama Karin has magic rings that let people transform into Greek gods.
  • In Dragon Ball Z Bulma makes Gohan one (a watch) so he can fight crime as THE GREAT SAIYAMAN! Later on Videl gets one too.
  • Used in the TV adaptation of Skull Man. Coupled with Body Horror and Nightmare Fuel.
  • Fine and Rein of Fushigiboshi No Futago Hime each have a Sunny Luce, a compact that allows them to use the power of The Prominence. They can also use it to call on their Sunny Rod without being transformed.
  • Puella Magi Madoka Magica: '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 Power Crystal of some sort when transformed. And the name is quite literal.
  • Ai from Dragon Crisis! has a transformation trinket that has been imbedded inside her body that lets her transform into a pseudo-werewolf.
  • The two sisters in Makeruna Makendo use an elephant wand and a striped baton.
  • Lime's choker in Jewel BEM Hunter Lime.
  • The Burst Hearts of Pokemon Re Burst.
  • The titular ribbon from Hime-chan no Ribon, which has various handy powers, primarily allowing Himeko to turn herself into whoever she wants for one hour.
  • Shugo Chara! has the Humpty Lock which Amu uses to fuse whichever Guardian Character's egg she needs for the situation to transform. Ikuto uses the Key that is paired with it. Everyone else just directly transforms with their Guardian Character.
  • In Episode 2 of Higurashi: When They Cry Kira, Rika and Satoko were given staves that allowed them to transform into magical girls.
  • Butsu Zone - Sannju's armring.
  • Ao no Exorcist has the Kurikara, a demon-slaying sword. When drawn, Rin becomes covered in blue fire and becomes more demonic looking, with bigger fangs, ears, and Fireball Eyeballs. Unusually, he's actually extremely powerful even when it's sheathed. Then again, Kurikara is more Power Limiter that contains his Demon Heart and Rin is a Half-Human Hybrid who already had Super Strength even before the seals on him were undone.
  • The titular heroine of Nurse Angel Ririka SOS transforms into Nurse Angel using a magical hat which she got as a present.
  • Gatchaman Crowds uses notebooks. That triple as communication devices and a way of becoming Invisible to Normals.
  • In Magi – Labyrinth of Magic, mastery of a Metal Vessel allows it to be this, where the user combines with the Djinn contained within to enter a Super Mode.
  • Umi Monogatari has the Bermuda Stones, which turn Marin and Kanon into priestesses. Which makes it a bad thing when Sedna destroys them.
  • Fate/kaleid liner PRISMA☆ILLYA: The Kaleidosticks allow its users to enter a Magical Girl trance, granting them access to an unlimited supply of mana. The Class Cards also serve a similar function when installed, granting the user access to the powers of the Heroic Spirit it is based off of.
  • In Guardian Fairy Michel, the fairies act as living examples, giving their powers to Michel, who amplifies them.
  • The Triggers in World Trigger are necessary to enter a Trion body, which is super powered and also invincible to anything except Trion attacks. The equipment of the body depends on the programming of the Trigger while the raw power depends on the person using it.

    Comic Books 
  • Donald Blake's cane allows him to transform back to his true form, The Mighty Thor, 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 DC Comics' 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 "unusual" powers to turning the wielder into yet another Flying Brick.
  • Darla Deering uses the "Thing Ring" mentioned in the Western Animation section to summon her Miss Thing armor in FF.
  • Dan Garrett, the first Blue Beetle, 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... except it has attached itself to his spine.
  • Jack Ryder used the Molecular Transducer to turn into The Creeper.
  • Rather than transforming him, Rick Jones' Nega-Bands activated a hyperspace link that allowed him to switch places with Captain Marvel, an alien hero who was stranded in the Negative Zone.
  • The Fly, an Archie Comics hero, originally used a magic ring to transform into his superhuman form; when DC Comics 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 Astro City, Winged Victory's logo-shaped necklace serves this function in her civilian form.

  • Inverted in Wolf, the amulet is supposed to prevent Will (Jack Nicholson) from transforming but at the end he discards it and becomes a full wolf.

  • Hank McCoy makes a serum that temporarily reverts him from "blue Beast" to "Nicholas Hoult" in X-Men: Days of Future Past. 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.

  • The young adult novel The Monster's Ring by Bruce Coville (part of the Magic Shop series) is pretty much about Exactly What It Says on the Tin...a ring that turns the wearer into a monster.
  • In the Rainbow Magic 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.

  • The Spirit Sticks in Magical Girl Policy.

    Live Action TV 
  • Kamen Rider 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 Super Mode:
    • 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 Shin Kamen Rider: Prologue; let's just say that its protagonist is closer to (a gorier version of) The Incredible Hulk than a Kamen Rider...
    • 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.
    • Kamen Rider Agito'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 Iron Man, suitcase version.)
    • The Riders of Kamen Rider Ryuki, Kamen Rider Blade and Kamen Rider Decade 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 Kamen Rider Faiz fulfill two expectations at once, by using cellphones that slot into their belts.
    • The Riders in Kamen Rider Hibiki don't use belts but rather soundwave-activated items to transform.
    • The various Riders in Kamen Rider Kabuto use "Zecters" (robot insects or, in one case, arachnid) that usually mount on the belt buckle; TheBee and Kabutech Riders from The Movie put theirs on wristbands, and Drake and Sasword use their weapons as their trinkets instead.
    • Den-O, who has a train motif, uses a smart-card akin to the Suica system, with the belt acting as the card reader.
    • Kiva's Transformation Trinket is Kivat, his kinda-sorta-robot bat sidekick. Kivat's bite causes the belt (and Fangire Game Face Facial Markings) to appear, and Wataru places Kivat into place as the buckle to initiate transformation. The IXA system requires the IXA Knuckle weapon, which links up with the belt that totally wasn't there before 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.)
    • Kamen Rider Double 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 drug-like effects of the Gaia Memory. The Monsters of the Fortnight uses Memories without Drivers, whereas major characters possess Drivers.
      • For Double himself, he's made up of two people through Sharing a Body. 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 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 Xtreme Memory is used, it's a proper Fusion Dance 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.
    • Kamen Rider OOO follows in the tradition of 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 Rule of Three is a recurring motif, this isn't accidental.
    • Kamen Rider Fourze 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 Zodiarts use Zodiarts Switches to transform, and the Horoscopes have special unique Switches.
    • Kamen Rider Wizard 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 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? Actually, it's the Phantom monster inside him, whose powers he can draw because he was Badass enough to resist the "drive you to despair and burst out of you" process.
    • Kamen Rider Gaim 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. It's a Double situation where the Driver makes a harmful power source safe. Which will come in handy when the Alien Kudzu that spawns the fruits that the Lock Seeds are made from replaces all plant life, as it is expected to in ten years.
    • Kamen Rider Drive has a fancy belt, and it's called... wait for it... the Drive Driver. However, it's actually a Robot Buddy type AI that is actually actually the inventor of the tech, saved by Brain Uploading. We think. Shinnosuke calls him "Mr. Belt." (Belt-san.) Its ever changing display is full of Mythology Gags, taking on a face like Kivat (the last sentient belt) or a spinning wheel that resembles the turning of the turbines in the Typhoon belts. But for the first time since Kamen Rider Amazon, the belt isn't the full transformation device. It is a two-parter where the Shift Cars are placed in the arm-worn Shift Brace, for a transformation process that's nigh identical to that seen in ToQger, which it airs alongside, while it requires the belt to detect and process the powers of the shift car inserted, as seen in episode 3 where he can't transform until Tridoron delivers it Just in Time and he dons it, despite the fact that he'd already been wearing the Shift Brace and had a Shift Car.
    • Subverted in Kamen Rider: The First and The Next, remakes of the original series and Kamen Rider V3 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 Gratuitous English. Some of the best belong to Faiz (which may have the sexiest voice of any Transformation Trinket), 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).
  • Power Rangers and Super Sentai 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 Gekiranger and the sunglasses-styled Solar Morphers in Jungle Fury, for example. The Dino Buckler is the most iconic, being the original Power Morpher seen in Mighty Morphin' Power Rangers, and was belt-worn while transformed.
    • Then there's the Power Rangers S.P.D. 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 Early Installment Weirdness: We actually don't see change devices until the fourth series. In Himitsu Sentai Goranger, the unmorphed Ranger jumps and yells "Go!" and a Repeat Cut has them fly through the air again, but now suited (meaning we also don't get the first Transformation Sequence in season one, either.) In J.A.K.Q. Dengekitai, 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 Battle Fever J the heroes say "Fever!" and turn around once, though the first time, they actually had to physically put on the suits. (This was most likely an artifact of the show's original intentions of being a Japanese adaptation of Captain America.)
    • Kaizoku Sentai Gokaiger follows in the tradition of Kamen Rider Double and Kamen Rider OOO in that the cell phone morphers (the Mobirates) are just holders for the real transformation trinkets, the Ranger Keys: the 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.
      • Power Rangers Turbo 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 The Movie.
    • Before them, Mighty Morphin' Power Rangers' Power Coins did way more than morph the Rangers (which, under special circumstances, they could do without the morphers.)
    • In Power Rangers RPM, it's Engine Cells. A variety of them are placed in a variety of things, including the morphers (cell phones for the primary colors, wrist-worn for Green and Black, weapons for 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 Core Medals.
    • In Engine Sentai Go-onger, which is a more lighthearted series, the Engine Souls are more plot points. An Engine is an alien Robot Buddy that can only operate for so long at its proper Humongous Mecha size under Earth's conditions, and after a time will revert to Sleep-Mode Size, which takes the form of an Engine Cast (the toy-sized body) and an Engine Soul (exactly 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.
    • Zyuden Sentai Kyoryuger, 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 Sixth Ranger, who was born before the existence of guns and uses a large wrist-worn crossbow-like device, and the first two Guest Star Party Members, 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 To Q 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.
    • Shuriken Sentai Ninninger goes back to the logic of Kyoryuger's weapon-based trinkets, this time using large swords and transformation shurikens for the ninja theme.
      • The sixth ranger's got it worse: His is based on a cheeseburger phone, with his golden Shuriken being the cheese.
  • The Ultra Series typically has the human host of each title character use an activator device to initiate the change.
  • Madan Senki Ryukendo is another case of the weapon itself being the transformation item.
  • On The Mystic Knights of Tir Na Nóg, the Mystic Weapons are also the transformation trinkets.
  • In Superhuman Samurai Syber-Squad, 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 Rule of Cool or Rule of Funny, 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 Stargate SG-1 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.
  • Tomica Hero Rescue Fire combines this with Calling Your Attacks 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.
    • Subverted in Tomica Hero Rescue Force, its predecessor. While they indeed use a device to transform (specifically, the Nintendo DS-shaped Rescue Commander and an activation card), they have to enter transformation tubes similar to the aforementioned JAKQ, which gives them their suits. The exception is the movie-exclusive R0, whose suit comes from his vehicle.
  • 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.
  • Once Upon a Time:
    • Similar to the Wolf one above; 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.
    • Regina gives mermaid Ariel a bracelet that allows her to assume human form, but with an Equivalent Exchange element that forces another person to become a mermaid. Later, after Regina's Heel–Face Turn, she alters the bracelet so that Ariel can assume both human and mermaid forms whenever she desires, without any negative impacts.
  • BIMA Satria Garuda has the red Power Stone for the hero, while apparently differently colored ones are used by villains.

    Video Games 
  • The Manaketes in the Fire Emblem series generally require an item called a dragonstone to transform into their true forms. As dragons, they tend to have little trouble destroying the opposition, but once the stone runs out of uses and breaks, they're helpless 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 Fire Emblem Awakening, 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 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.
    • While not a Manakete, the Avatar in Fire Emblem Fates (Along with any of their potential children) can also use a Dragonstone to transform. In their case, it's needed to retain their sanity and avoid going on a rampage like when their power first awakened.
  • Link gets a few of those in several games.
    • In The Legend of Zelda: Majora's Mask, several masks are used to transform Link into other races, and the Fierce Deity Mask transforms him into... guess what.
    • In The Legend of Zelda: Twilight Princess, 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 Plot Coupons essentially act like this for Midna.
  • Viewtiful Joe has the V-Watches. Henshin a go-go, baby!
  • Kingdom Hearts outright states that Sora's newer, black clothes are the Transformation Trinket 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 Heartless) They also help him absorb MP from the air, which is why the Magic-system in Kingdom Hearts II differs from that of the first part.
  • The biometals in Mega Man ZX and Geo's Transer/Star Carrier (With Omega-xis) in Mega Man Star Force. 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 Mega Man Battle Network 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 Mario Game, there's a new item that gives Mario and Luigi a new form in addition to new abilities.
    • In Super Mario Bros., it began with the famous Super Mushroom (doubles Mario's size and grants an extra Hit Point), the Fire Flower (shoot fireballs) and Super Star (invincibility).
    • Super Mario Bros.: The Lost Levels (the Japanese sequel) introduced the infamous Poison Mushroom, which inflicted damage instead of powering up Mario.
    • Super Mario Bros. 3 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 Super Mario World.
    • Super Mario World 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.
    • Super Mario Land 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.
    • Super Mario Land 2: 6 Golden Coins 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.
    • Super Mario 64: 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 Super Mario World or gets a feather and become Wing Mario.
    • Super Mario Sunshine 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 Super Speed.
    • New Super Mario Bros. 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 One-Hit-Point Wonder that can float through the air, fit into incredibly small pipes, and and run across water.
    • There are seven forms this time in Super Mario Galaxy (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 Hub Level, 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.
    • New Super Mario Bros. Wii 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.
    • Super Mario Galaxy 2 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).
    • Super Mario 3D Land saw the return of Tanooki Mario minus the flight and statue capabilities (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, which allows Mario to throw boomerangs.
    • New Super Mario Bros. 2 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).
    • New Super Mario Bros. U sees the return of the Super Mushroom, Fire Flower, Ice Flower, Mini Mushroom, 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-<recipient>, a powered-up Flying Squirrel form capable of infinite flight).
    • Super Mario 3D World 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 that kind) that allows them to run up walls and tackle enemies, among other things.
  • Pokémon
    • 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 Sky Forme. For the latter though, the transformation does not work at night and it can be canceled by Shaymin being frozen.
    • Pokémon X and Y introduces "Mega Evolutions", which allows a small selection of pokémon to take on their Super Mode forms during battle. The Transformation Trinket 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 Key Stone to be held by the trainer (usually in the form of an accessory such as a ring or braclet), which is used to actually trigger the evolution.
  • In addition to the usual Mega Manning, some Kirby games have Copy Essences lying around that grant an ability when touched. In 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 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 Muppet Monster Adventure , 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.
  • Silent Hill 3 has the Princess Heart Transform Costume, which is activated by a key-shaped trinket.
  • Sonic the Hedgehog, once you collected the required Green Rocks. The most famous being the seven Chaos Emeralds to become Super, on in Blaze's case, the seven Sol Emeralds. The Sonic Storybook Series also bring us two new forms thanks to the seven World Rings, and four Sacred Swords.
  • The sequel for Ni GHTS Into Dreams features persona masks that transform the Nightmaren in a Dolphin, Rocket and finally a Dragon.
  • In Amagon, Amagon only becomes able to transform into Megagon once the Mega-key is found.
  • In The Legend of Dragoon, the main cast members possess colored crystal orbs called Dragoon Spirits that allow them to change into winged, armored warriors, complete with Transformation Sequence.

    Visual Novel 
  • The accessories in Princess Debut let your main character don one of 20 different ballroom-ready costumes.
  • In Long Live the Queen 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.

    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 Sluggy Freelance, 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.
  • In Agents of the Realm, each Agent has an amulet made from part of the Provenance which enables transformation into Frills of Justice.
  • Yuuki in Sparkling Generation Valkyrie Yuuki (a parody of Magical Girl 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 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 Panthera team has an amulet on a necklace "that contain[s] minerals that ease the transformation and help focus [their] elemental power" [1].
  • In El Goonish Shive, the Transformation Gun derived Cat Belt which has two buttons "Feline" and "Human".
  • 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 To Prevent World Peace, every Magical Girl 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.
  • 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.
  • Magical 12th Graders: The pin, a magical artifact that can transform anyone into a magical girl (including boys, though their outfits are suitably masculine). The cubics, little pieces of the pin that broke off, can be used for the same purpose, though they're less powerful.

    Western Animation 
  • In the Ace Ventura 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.
  • The Omnitrix from Ben 10 is Clingy MacGuffin that lets Ben turn into (initially) ten different aliens. The watch tends to not turn him into the alien he wants hinting that the device might be sentient.
  • One episode of Danny Phantom involved an amulet necklace that would turn the wearer into a dragon whenever they get angry.
  • El Tigre: The Adventures of Manny Rivera: a spinning belt buckle.
  • In Fred and Barney Meet the Thing, The Thing from Fantastic Four, instead of being permanently changed into a rocklike form, could go back and forth at will using a ring. The Fantastic Four guest appearance in Spider-Man: The Animated Series saw him being given this ability by Doctor Doom, but, of course, he doesn't get to keep it for good.
  • He-Man and the Masters of the Universe (1983): He-Man had the Sword of Power.
  • Jerrica Benton's Jem Star Earrings from Jem and the Holograms.
  • In the Hanna-Barbera cartoon Mighty Mightor, Tor had a magical club that he used to transform into the title character.
  • In My Little Pony: Friendship Is Magic, the six Plot Coupons obtained over the course of Season 4 become the keys for the Chest of Harmony, which transforms the Mane Six into Rainbow Power mode.
  • Pop Pixie has the Magic Pops, which let the pixies transform into Pop Pixie form and get a major power boost.
  • Princess Gwenevere and the Jewel Riders used Power Crystals.
  • She-Ra from She Ra Princess Of Power had the Sword of Protection, which was basically the Sword of Power with a few extra tricks and a jewel.
  • SheZow: SheZow's Glamazon Power Ring, probably also the source of all of Guy's powers. Also counts as a Clingy MacGuffin.
  • The Skysurfers from Skysurfer Strike Force use watches called Digitrans to transform themselves into their hero identities and their cars into flying surfboards.
  • 1950s cartoon Tom Terrific was able to morph into anything thanks to his magic funnel.
  • W.I.T.C.H. had the Heart of Kandrakar/Candracar. The funny thing about it is that all five girls used the same trinket. Anyone not around when Will used it wouldn't transform and couldn't until they met up with Will.
  • In Winx Club, the Mythix wands are required to unlock the Mythix transformation and are seen in the Transformation Sequence.
  • 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 Dragon Booster 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 Catchphrase, but that's another trope entirely.
  • Each of the three main characters of Lolirock has one of these, and it glows as soon as the transformation starts. In one episode, Iris loses hers, and she doesn't realize it until when she wanted to transform (it is hanging from her neck, after all).
  • In Miraculous Ladybug, 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.
  • Dragon Tales has a unique spin on the trope- two kids utilize a magical dragon scale (in conjunction with a chant) to travel to and from Dragon Land. So it's a Transportation Trinket.
