Transformation Sequence



""It's Morphin' Time!""

- Mighty Morphin Power Rangers

Before the Ordinary High School Student (or a hidden Bad Guy) can access her (or his) secret powers, there must be a power-up. This usually involves a change of form or at least costume, although the precise mechanisms usually vary by type. In Japanese television, this is called (a) henshin. By genre, this usually goes as follows:


 * Magical Girl: Our heroine usually utters a key phrase, accompanied by certain gestures and/or using some sort of magical device, and then hovers into the air over a magical background, then has her clothes disappear as her hero costume glows into existence over her until all her ribbons, jewels, feathers and assorted frippery have formed. Despite being strongly associated with Magical Girls there are several "magical boys" who have comparable sequences, though their outfits are usually more like uniforms or armour.
 * Henshin Hero: Similar to the Magical Girl but usually less elaborate and more awesome, our hero uses his special device (often a weapon) and/or shouts his transformation phrase to turn into his superhero form in a faster but equally flashy sequence, that for some reason often involves lightning, glowing or shining, and the hero announcing himself.
 * Super Mode: An already-powerful hero or villain becomes even more powerful to face the latest threat. While generally not as elaborate as the previous two transformation sequences, it often signifies a more intense upgrade. The raised power level is usually indicated by a colour change, glowing eyes (or hair) or appearance altered in other ways than a wholly new costume and accessories.
 * Monstrous Transformation: A darker and more physical sequence, usually when a humanoid character becomes more monstrous before our eyes -- often involving bulging muscles, ripping clothes, (to various extents) and often implications of pain, especially in a horror-themed series. Werewolves, Jekyll and Hyde, and other magical or chemical induced transformations usually fall under this.
 * Mechanical Sequence: A Humongous Mecha or Power Armour wearing hero gets into battle mode, whether through transforming, combining, adding the gear, and/or just plain launching into battle. Usually contains as much Technology Porn as time and budget will allow, and are very often tool-assisted in some way as the base's machines use mechanical arms and such to remove and add components.
 * Size Increase: An already formidable monster or hero doesn't make many physical changes but simply increases their size massively, often to Kaiju levels.
 * Other Sequences: Ones that aren't covered by or overlap with the above include Mon "evolution" sequences (which are sometimes permanent), characters combining into one, or more mundanely, a Superhero donning their outfit via conventional (if accelerated) means.

Transformation Sequences are good for a show's budget because they provide a large amount of Stock Footage that can be (and often must be) reused each episode. They also provide nice filler for the writers. If a particular transformation sequence occurs multiple times in one episode, a shortened version will often be used after the first time (hopefully).

Rarely is there a special-effects sequence for changing back.

It seems to be an unwritten rule that evil characters almost never get a Stock Footage transformation sequence, instead opting for a special-effects-assisted "insta-transformation", a single sequence in the case of one-shot villains, or just transforming offscreen. This is a good way to spot the Sixth Ranger Traitor or a Noble Demon looking to make a Heel Face Turn somewhere down the line.

Note that many transformation sequences are actually just for the viewer's benefit (and to eat up air time), and the actual change as experienced by the character is instantaneous -- or at least very brief. This might explain why bad guys (almost) never attack a hero during his transformation sequence, although the Dangerously Genre Savvy usually will not let the opportunity slip by. This may result in an unstable Partial Transformation.

Compare Gorgeous Garment Generation, Creation Sequence, Fighter Launching Sequence, Lock and Load Montage, and Suit Up of Destiny.

Anime and Manga
"Ryoma: "What's the matter? Can't even pull off a change without checking the controls?""
 * Cutey Honey is the archetypical transforming Magical Girl, including catchphase, naked transformation, and In the Name of The Moon. However it should be noted that in the original series, Honey's transformation was very short and to-the-point, clocking in at only 5 seconds or so — a far cry from the minute-long lightshows of modern-day Magical Girls.
 * And the live version...well, just look. ("Honey Flash" indeed...)
 * Sailor Moon, with its heavy dependence upon stock footage, used pretty much every variation of the Transformation Sequence over the years and codified the modern Magical Girl transformation.
 * Transformation sequences gradually evolved over the course of each season as the novelty wore off: condensed, "team transformation" sequences created by intercutting the various characters' individual transformation sequences predominate in later episodes.
 * In SuperS, Sailor Moon and Chibi Moon shared a sequence. What would happen if they had to transform separately was never addressed.
 * In Ami Mizuno's Day in The Limelight episode of Sailor Moon R the camera actually cut away from her Sailor Mercury transformation sequence twice. The sequence appears to be happening in real time and her opponent appears to transfixed by the light show.
 * When we actually see a character (namely, Sailor Uranus) transform back on-screen, it apparently requires only an act of will, as opposed to the "By the Power of Greyskull" phrases used for normal transformations. Also, there are a few plot-critical moments at which Sailor Moon is temporarily depowered by a villain, reversing her transformation; these, however, are obviously not voluntary.
 * Amusingly, for all of the girls' transformations, we see Tuxedo Kamen transform three times over the course of the series. Once before Mamoru knew of his alter ego, once with a rose after Usagi outs herself as Sailor Moon to him, and finally, during a meeting with the Outer Senshi. This last one is noteworthy because it's the shortest henshin of the series. After the three lengthy transformations of the Outers, Mamoru transforms fully in the time it takes for a leaf to blow past the screen.
 * Similarly, Tokyo Mew Mew shows Mew Ichigo voluntarily transforming back into her normal form at least twice (with no nudity shown), seemingly just by touching her pendant; in the last episode, the entire team gets their transformations reversed because their powers are no longer needed.
 * Mermaid Melody Pichi Pichi Pitch gives everyone two separate sequences; one if they're in human form, and one if they're mermaids. Also, once they get their first wardrobe and weapon upgrade, it appears that Lucia, Hanon and Rina cannot transform separately until near the end of the season, for the simple reason that the animators didn't make the necessary Stock Footage.
 * Saint October dispenses with glittery body outlines and comes up with things like... fruits falling down from a tree and covering the magical girl. See for yourself.
 * Moldiver parodies the conventions with a transformation that destroys clothing unless the transformee strips naked first.
 * Similarly, Poemi Watanabe's transformation to Puni Puni Poemi automatically strips her bare -- except for her socks, which she has to manually remove before she can complete the sequence.
 * Was done in an adaptation of Zorro (Kaiketsu Zorro, to be exact). Regular Zorro. He transformed.
 * With lightning. And generic Latin music. And one of the first males to ever transform; see Crowning Moment of Awesome.
 * The majority of protagonists, antagonists, and minor enemies in Guyver are capable of changing to and from incredibly strong and sentient beings; the most prominent is the main character, Sho Fukamachi (a.k.a. "Guyver 1").
 * Fullmetal Alchemist: Envy unleashes his gruesome true form inside Gluttony's stomach. Complete with "Oh Crap" expressions from Ed and Ling.
 * Parodied in Hayate the Combat Butler; Hayate once drew a manga about a magical girl that won a manga contest. When he showed it to the other girls at their insistence, the girls noted with some irritation that the transformation sequence was too Moe and full of Fan Service.
 * The Transformation Sequence in Futari wa Pretty Cure is unusual in that it requires both girls in the show to invoke it together; it is also extraordinarily pyrotechnic in appearance.
 * The "implied nudity" present in almost every transformation sequence in anime is only present in the original Pretty Cure and Max Heart; subsequent series have the girls go from civilian clothes straight to glowy shapes which explode into the new outfit.
 * Heartcatch Pretty Cure has the girls wearing dresses made of light in their respective colors at the beginning of the transformation sequence.
 * Suite Precure has brought back the glowing nudity.
 * Mercifully in Yes Precure 5, the individual girls' sequences are very brief and often happen simultaneously via split-screen. Five long transformation sequences may be pretty and cheap but it ain't half boring the umpteenth time.
 * Macross had a mechanically detailed slow-mo sequence of the Valkyrie's shape-shift in the opening, but most times the changes happened lightning-fast, without Stock Footage (in fact, the mecha fighting style shown in Macross depends heavily on moment-by-moment management of the correct transformation mode for the situation). The later Macross series generally followed the lead of the first, although beautifully animated slow-motion transformations (as in Focker's VF-0 transformation in Macross Zero) were retained, these sequences were mostly one-off Fan Service moments.
 * UFO Princess Valkyrie has at least 4 different transformation sequences, all of which provide plenty of Fan Service:
 * Let's not forget doing at least one of them, both ways, at least one per episode.
 * Valkyrie: a fairly standard transformation sequence, triggered by Valkyrie kissing Kazuto.
 * Hydra: another fairly standard transformation sequence, triggered by Akina temporarily removing the seal on Hydra's power.
 * Valkyrie Ghost: an evil-type transformation: involves lots of chains and darkness, appears to be painful, causes manacles to appear around Valkyrie Ghost's wrists.
 * Akidora: fairly standard sequence, this transformation combines Akina and Hydra, averaging their "assets"; introduced in episode 9 of season 2 and used 3 times in that episode alone (full-length every time), plus at least once more during the series. Triggered when Akina and Hydra are annoyed at each other, dissolves if they start feeling friendly toward one another.
 * A unique variant on the Super Mode sub-type appears in Mononoke (and the Bakeneko arc of  ~Ayakashi: Samurai Horror Tales~  from which it was adopted). In it, the Medicine Seller doesn't so much transform, as summon a warrior body to replace his normal one. The elaborately painted patterns on his blue robes and pale face slide off, instead crawling onto his other form's golden robes and dark-skinned face before his original body vanishes in what is unquestionably one of the most unusual transformations ever animated. And each sequence is slightly different from the others, ensuring that the process never becomes redundant. No Stock Footage for the Medicine Seller, that's for sure!
 * Ronin Warriors had multiple Transformation Sequences for different levels of power.
 * Getter Robo, one of the classic Transforming Mecha series, subverted it when the prototype Getter units were destroyed as an enemy attacked in the middle of the transformation sequence. A modern sequel had the heroes pull the same trick against their Evil Counterparts -- after doing their own combination sequence first -- to prove how much more Badass they are.

"Tsubomi is currently transforming. Please wait."
 * Then gleefully subverted with the revelation that the heroes only destroyed one of the machines. The other two formed enough of the machine for their enemies to keep fighting. Of course, one Stoner Sunshine later...
 * This scene seems to be based on the first battle in the Shin Getter Robo manga, though in that version they managed to destroy the partially-formed mecha before it could fight back.
 * Zettai Muteki Raijin Oh took this trope to epic levels early in the Super Robot genre -- Not only does the titular combiner have a gattai sequence, the classrooms of the school transform into a command centre, with the whole structure of the school building rearranging itself. The three pilots do a whole To the Batpole sequence, and the school hall, pool, and sports track all unfold to reveal the three component robots of the titular mecha. As shown Here
 * Taken one step beyond in one of the later Eldoran Series anime, Nekketsu Saikyo Gosaurer Where the school it self turns into the mechas. Observe
 * Spoofed in episode 41 of Keroro Gunsou, where Tamama suggests the squad attack Kogoro during his Transformation Sequence, but Keroro insists they wait until it's finished.
 * In Princess Tutu, you can tell the Dark Magical Girl by the pain she goes through when transforming -- black wings rip out of her back and thorny vines wrap around her as she voicelessly screams. The title character, however, gets a regular Transformation Sequence with glowy body outlines and beautiful water, egg and light imagery.
 * The main character also has a short transformation sequence that takes place when she turns from a duck into a girl, although we see the transformation from the viewpoints of outsiders about as many times as we see the sequence, and it seems like most people simply see it as a bright flash of light followed by a naked girl standing where a duck was a moment earlier. Also, it's a little interesting to note that in comparison to a lot of other magical girl shows, Tutu's transformation sequence is very short -- the main character only disappears into a golden egg for a moment and comes out fully clothed. The promo video made before the show was produced shows a much longer, more traditional transformation sequence, however.
 * Parodied nicely in Genshiken; when forcing Saki to cosplay, a somewhat...unhinged... Ohno, with a creepy laugh and in a sing-song voice, says "Time for all the gentlemen to get out of here, so Saki can begin her transformation sequence".
 * Parodied in Asagiri no Miko where during one monster attack Seiko orders the girls to "Transform!"... And they run into a locker room and laboriously change into their miko clothes.
 * Magical Girl Lyrical Nanoha features long transformation sequences for the heroine and her female comrades. Notable for the nudity of the heroine even when she was a minor, although no secondary sexual characteristics are depicted. In certain cases, even the weapons get their own transformation sequences. In the third season, Nanoha StrikerS, the clothes of the only male on the team explode directly into his Barrier Jacket with no implied nudity in between -- particularly conspicuous next to the consecutive transformation sequences of the females, who have their clothes explode long before the Barrier Jacket appears.
 * Said sequences happen in decreasing frequency through subsequent seasons. A's has the characters perform the transformation sequence twice for the whole season, while StrikerS also had it twice for the main characters only during its 26-episode run. Heck,  who were introduced in the second season did not have a transformation sequence until the third season, and it was very brief. After transformation sequences have been done previously, the characters usually just gets enveloped in a ball of light and transforms in a split second.
 * Doubly subverted in the second episode of the first season where a giant dog of a Jewel Seed monster attacks Nanoha during her Transformation Sequence... only to get tossed away like a rag doll by the powerful barrier it generates.
 * Vita in A's also attacks the bubble of energy surrounding Nanoha while she's transforming. The bubble explodes but she's too late because Nanoha is able to flee from it already fully clothed. This suggests it's possible to attack and disrupt a transforming heroine in Nanoha, it's just difficult.
 * We also see variations on transformations, including one that is virtually instant (Nanoha says simply, "Raising Heart, please?" and her Jacket flows over her), and numerous detransforms that are not only simple but clearly triggered just by willing them.
 * The transformation sequence in The Movie only appears once each for Nanoha and Fate, thankfully. However, the previously missing secondary sexual characteristics were this time included.
 * The Magical Girls of Studio Pierrot each have a Transformation Sequence:
 * Yuu from Creamy Mami has a static one featuring strobe lights and golden rings all around her body, after which she quickly grows into her Older Alter Ego.
 * Persia the Magic Fairy has one that begins with baton-twirling and a brief dance, and continues with heart and bubble imagery. The actual transformation part is quite brief though.
 * Magical Star Magical Emi has one with lots of bubbles and wand-waving, where again the actual transforming part is quite brief.
 * Miho from Magical Stage Fancy Lala grows into her Older Alter Ego while surrounded by floating pink and blue ribbons.
 * Floral Magician Mary Bell has a nudity-free one in which her clothes change into sparkles and re-form themselves as her Magical Girl outfit. She also gains an oversized hairbow.
 * Being one of the older Magical Girl shows, Hana Noko Lunlun has a rather simple transformation: Lunlun points her Transformation Trinket at a nearby flower, and the flower emits rings of colorful light towards Lunlun, thus changing her outfit to whatever she needs at the moment. However, the nudity and floating/dancing-around-in-a-void present in later Magical Girl shows are absent here.
 * Yami Yugi's appearances in the early episodes of Yu-Gi-Oh were usually preceded by a Transformation Sequence. After a while they cut this short, but the dub version left it in for a while afterward.
 * Yu-Gi-Oh the Abridged Series called it "Puberty Power" as Yami Yugi looks like a taller, older version of the regular-flavored Yugi
 * In the second season of Yu-Gi-Oh 5 Ds, when someone starts a Riding Duel on the highway, it reconfigures itself to allow the duelists to enter the Duel Lanes.
 * Then, the transformation sequences at the end of the second season, when Dark Glass summons his D-Wheel and dons his riding duelist outfit in a flash of green computer coding. Placido displays one of the most bizarre sequences ever seen in the franchise when he reveals himself as an android and merges himself with his D-Wheel. Just watch.
 * Yuma gets into the act, too. "Duel Disk, goooo!! Duel Gazer, let's roll!"
 * Subverted in Cardcaptor Sakura, where title character Sakura doesn't change, instead transforming the tiny gewgaw she wears on a necklace into a three foot long staff which she needs in order to use the magic cards. Any changes to her wardrobe are done in an entirely non-magical way. These staff transformations don't use Stock Footage, since Sakura averts Limited Wardrobe hard.
 * Konjiki no Gash Bell featured a parody of the elaborate transformation sequence, with one-shot villain Coral Q able to transform into a variety of forms to counter Gash's spells. He takes great pride in these transformations (with theme song sung by sentai mainstay Hiroki Takahashi), and Kiyomaro counters them by simply saying he blinked and missed them, forcing Coral Q to de-transform and re-transform.
 * Kiyomaro makes Coral Q do it over several times -- for the first two, he did miss it: Coral Q goes from being a laughably tiny half-transformed box-like thing to a ridiculously giant robot in an instant. Kiyomaro makes him do it over twice because he's convinced that he somehow missed a step...and then he gives up trying to figure it out and starts screwing with Coral Q.
 * Capcom has been experimenting with this a lot lately in the Rockman/Mega Man series. Cross Fusion starting in the third season of the EXE/NT Warrior anime, Denpa Henkan/EM Wave Change in the new Ryuusei/Star Force game/anime, and the "Rock On!" ability that underpins the [ZX series.
 * Specifically, in Mega Man ZX Advent, Ashe and Aile get full-on Magical Girl-esque transformations (Vent and Grey's transformations are similar, but much shorter; Grey's appears to be a Painful Transformation).
 * Even earlier, in Mega Man 6, selecting the Rush Jet(pack) and Rush Power would be accompanied by a mini-cutscene (thankfully skippable) that shows Rush teleporting in, transforming, and flying over to Mega Man, who would then fly up or punch. Mega Man 7 streamlined it: Rush teleports, jumps over Mega Man's head, transforms, and falls onto him in the space of a couple of seconds. Interestingly, this was the game where Rush could be hit by enemies and would retreat. No enemies were Genre Savvy enough to take advantage of this except by accident, though.
 * Mega Man X kinda gets one when he enters a Light Capsule. He gets surrounded by glowy lights, a lightning bolt strikes the capsule, the new part appears, and X raises his fist (with the recurrent Audible Sharpness sound) and demonstrates his new power.
 * Double Subversion in Voltron. During one episode, the villains decide to attack Voltron while it is transforming. Unfortunately for them, they find out that a force field protects Voltron while it is transforming.
 * Not true in Voltron Force. In the episode Flash Form Go, Voltron's transformation is repeatedly disrupted by a monster. Turns out 36 seconds is a long time to be defenseless. The team questions why it never happened before, which may mean the above-mentioned scene is no longer canon.
 * Similarly, Gao Gai Gar is surrounded by a tornado of greenish energy during its Final Fusion sequence. This time triple subverted when at least one Monster of the Week was actually able to breach it and attack the machines in the middle of transforming, and had to be distracted by another Brave robot.
 * Gao Gai Gar also had to fight off the second Monster of the Week himself in mid-transformation.
 * It should also be noted that at least twice Gao Gai Gar is shown to perform "Fusion Out" with help of hangar machinery, making it a rare demonstration of the nominal way of ungattai-ing the combined mecha.
 * The earlier Brave show Brave Express Might Gaine had no such protection & actually did get attacked mid-gattai by a Genre Savvy opponent at least once.
 * The title mech of Gravion is surrounded by a huge bubble of turbulent gravity-manipulation as its parts join together. Notable in that even the pilots of the separate machines have to be careful and concentrate on what they're doing, or it's quite capable of knocking them away too.
 * Subverted in Gravion Zwei, where
 * The invincible while transforming part was also subverted in one episode of Vehicle Voltron/ Dairugger XV. Specifically one of the units that made up the left leg was knocked out of formation (and the pilot stunned) leaving Volton hopping around one one leg while the other units that make up the missing leg cover their downed comrade.
 * It also made for an odd logic exercise since for the entire set-up to work they not only had not use the stock footage but actually assemble the titular mecha from the head-down, the exact opposite direction to the normal from the feet up assembly shown in the stock footage.
 * Bleach: subverted for most characters where transformation sequences can be quite straight-forward and practical such as Ichigo transforming from human to shinigami with a simple smack via an appropriate soul-removal tool or popping Kon's pill form into his mouth. It tends to be played straight when seeing a character's power-up transformation sequence for the first time (such as a powerful Arrancar entering Resurrection form or a shinigami activating bankai). However, some shinigami who rarely activate their shikai forms will get a dramatic sequence as well.
 * It was also played straight with the Magical Girl parody of Charlotte Coolhorn in the anime.
 * Averted in Galaxy Fraulein Yuna where one of the characters has a literal three frame transformation from normal clothing to battlesuit. Phenomenally cool.
 * Subverted in UFO Robo Grendizer (Westernized as "Grandizer"). The villains exploited a design flaw in the Grandizer unit -- as it left its ship (its transformation sequence), the pilot's seat took eight seconds to travel from the ship's control center to the robot's. The locals end up developing another support craft for the robot to respond to this, complete with its own full-time pilot.
 * Played straight with the Pilot's transformation sequence, announced with a roaring Dude Fureedo!
 * Subverted in the second episode of Ultimate Girls when Tsubomi and Vivian transform. Instead of the stock animation which is later used, a "now transforming" meter is displayed which looks suspiciously like an Adobe Flash Player loading bar.

"Biyomon: Biyomon digivolve to...*fails* Hey! What happened?
 * Tekkaman Blade has a rare male nude transformation sequence. However, the transformation sequence was pretty much dropped after about six or seven episodes. It was replaced with Stock Footage of the Humongous Mecha, Pegas, being deployed.
 * When Saban created their dub of the series, Teknoman, they reinserted the sequence into most episodes that didn't have it. It was even combined with the Pegas launch-sequence, creating a double-length sequence.
 * As for "detransforming", we see it twice. Once willingly and the other when In Tekkaman Blade II, it's given a more magical girl feel when Yumi does it.
 * Moka's super-vampire transformation in the anime version of Rosario to Vampire shows up nearly every time, and seems to have bats flying into her body and increasing her breast size. The DVD version goes a step further and removes the glow from her body, canceling out at least some of the Barbie Doll Anatomy. Come the second season, another, slightly more elaborate one is used.
 * Oh, and apparently this sequence happened in real-time and included a voice-over that was actually part of the sequence. Played for laughs in at least one instance when Moka transformed off-screen... and yet the voice-over describing what was happening could still be heard.
 * Guyver has a rare non-nude transformation sequence, as the Guyver Armor appears over any clothes the user is wearing. It additionally provides an explanation for why the user can't be attacked, as he's protected by a Sphere of Destruction during the transformation. In one of the early episodes, one of the Mooks attempts to grapple the hero in mid-transformation, and gets splattered into a fine meat-paste for his trouble. In another, Sho is chained to his girlfriend so that he cannot transform without killing her.
 * Wedding Peach had two, one for the wedding dress form, and one for their standard Magical Girl Warrior form.
 * To Love Ru: Lala's change into "Dress Form" somehow manages to combine this and Naughty Tentacles. Seriously.
 * Which is, unusually, skipped after just the first two episodes.
 * In To Love-Ru's Show Within a Show, Magical Kyoko, the transformation sequence is subverted. Kyoko, a magical girl, has a cat partner that transforms into her costume -- and only her costume. Kyoko has to manually put it on.
 * Subverted in Blue Dragon where as several robots begin to merge together in a transformation sequence, one of the heroes quickly slices them in half while berating them for thinking she would stand still and wait while they used such a long sequence during battle.
 * The Pretty Sammy series mostly plays it straight with an epileptic seizure-causing bit of Stock Footage, but sometimes parodies aspects of it. One of the first times Sammy transforms ends with her getting kicked down by Pixy Misa as she's posing.
 * Himeno Awayuki of Prétear has seven six available transformations, depending on the Leafe Knight she is merging with; all sequences look pretty similar, though. No special words are used, the process is triggered by joining hands. The de-transformations are also shown occasionally, but they don't get any special footage, and don't necessarily happen at her own will.
 * We get to see her merge with Shin in the manga. The Plant version outfit is actually rather cute. The anime only shows it once for a split second, when Himeno briefly goes through different Pretear forms during the Combined Energy Attack sequence. The transformation, on the other hand, is instantaneous.
 * Interestingly, there's also one episode where Himeno's transformation with Hayate is shown from outside, implying that it does take time (at least enough time for other Knights to comment on it); however, it could be that it was actually longer than usual,.
 * Onmyou Taisenki has a variation, in the form of Shikigami summoning sequences. Interestingly, pretty much everyone has them, and it's a pretty good way of telling how significant a Toujinshi is to the plot: important characters get long personalized sequences, while Mooks and Red Shirts all get the same generic sequence.
 * The Demonic subtype is played straight when the titular character of Naruto pulls out his
 * Do-chan, the sentient Battle Dogi from Ranma 1/2, isn't actually worn. When it finds a suitable master, it flashes into a bolt of lightning that crashes down on its owner, ripping her clothes to shreds (which leaves them naked momentarily,) and reforming on her body. It is also emphatic enough to know precisely when its owner wants to transform.
 * The Impulse Gundam from Mobile Suit Gundam SEED: Destiny uses a variation on the original series' Core Block System to launch -- the cockpit is a transforming fighter, the legs are a separate module and the entire upper body is a third, with extra equipment arriving as a fourth after the main body has combined in mid-air. Shinn is never attacked during that sequence.
 * No such luck for the protagonist of Victory Gundam, despite the Victory and V2 Gundams having very similar combining/transforming sequences to the original RX-78; well over half a battle can and is spent just trying to get all the pieces together without being interrupted or having said parts outright destroyed by the enemy, leading to such gems as Uso having to fight without arms or even legs.
 * Legs are just for decoration. The higher-ups simply don't understand that.
 * In contrast, G Gundam just went for straight up Fan Service. Unless there was some other deeper meaning I missed while watching the latex wrap snugly over Domon Kasshu's buttocks. In close-up.
 * Especially evident when Rain gets a sequence. Parodied with Master Asia's horse, who also gets to suit up.
 * Uta Kata has quite a bit of variety in its transformation sequences for Ichika, depending on which Djinn she summons. Each of her costumes is designed by a different well-known manga or anime artist. Ichika sometimes becomes fully naked, but also changes almost instantly on some occasions.
 * Shugo Chara, by its very nature as a Magical Girl series, has these — though, it adds some twists. There's a part-way "character change" that adds an accessory or two rather than a full costume, and the male characters' transformation sequences are as elaborate as the girls'. Also, Amu gets multiple transformations and . This trope is subverted hilariously on a couple of occasions: on one, Amu goes through the motions without her Transformation Trinket, only realizing too late that it won't work; on another, someone else triggers her transformation by tweaking the activation phrase! "Amu's heart: unlock!"
 * Kaze no Stigma is positively laden with transformation sequences, mainly Ayano Kannagi whipping out her sword Enraiha --- often several times per episode (or at least it felt that way).
 * Saber Rider and The Star Sheriffs has a "4 vehicles transform into one Mecha" every episode.
 * A staple feature of all incarnations of the Digimon franchise, to the point that to many they're the most memorable and recognizable point of the series. Transformation Is a Free Action is (almost) always in full play; however, it's widely implied that evolution takes only as long to happen as it takes for the evolving Digimon to announce their evolution.
 * There are numerous demonstrations that evolution takes next to no time across the franchise, but the most obvious example occurs in Digimon Tamers in the fight against Zhuqiaomon, where he fires an attack at the group, and only then Terriermon evolves, finishing up before the attack hits - i.e., less than a second! Later, the Digimon Savers Short Anime Movie verifies this notion - Agumon's evolution into ShineGreymon is shown both as the usual Transformation Sequence and as it would appear in-universe to the other characters. While the Transformation Sequence is the usual, the outside evolution takes less than five seconds, as demonstrated here starting at the 2:00 mark.
 * Digimon Adventure, despite being the one which set the trend for the franchise, loved playing with this trope on occasion. The forty-ninth episode played it to hilarious effect through combining it with Magic Misfire and Power-Up Letdown:

Patamon: Patamon digivolve to...*fails* Wait a second, I'm still me!

Tentomon: Tentomon digivolve to...*fails* KABU...never mind.

Agumon: Agumon digivolve to...*fails* Greymon! Greymon!! Greymon, yeah I'm Greymon! I'm big and I'm bad...*is stifled*"


 * Digimon Frontier plays this with amusing consistency: regardless of the form being transformed into, a single full Spirit Evolution sequence with no cuts will take thirty-two seconds. Lots of Barbie Doll Anatomy, screaming, and pretty lights ensue. It doesn't look like it, but Spirit Evolution is painful, and the amount of pain correlates with how powerful the form is (one word: ew). Takuya's voice actor, Michael Reisz, refused to voice Takuya's final evolution because he didn't want to harm his voice with all the screaming.
 * Dinosaur King uses transformation sequences for the six main dinosaurs (Chomp, Ace, Paris, Terry, Spiny, and Tank). Notably, they change from 2D chibi dinosaurs into CGI realistic dinosaurs. As the series progresses, they shorten these sequences, cutting from the chibi dinosaur straight to the CGI.
 * Inuyasha: Averted with the titular character. He becomes human for the night of the new moon but the transformation has little visible effect on his clothing and there's a brief pulse of power where his hair and eyes change colour and his ears shift from dog-like to human. In the manga, the transformation is almost instantaneous but the anime will draw it out for dramatic effect, especially when returning to his hanyou form. The transformation tends to be more dramatic when goes into his Super-Powered Evil Side mode but again, it's much faster in the manga and much more dramatic in the anime.
 * Both the manga and the anime tend to make Sesshoumaru's transformations into his true form dramatic but this is because he takes his true form so rarely there's clearly something very dangerous or important happening when he does.
 * Getsumen to Heiki Mina (aka Lunar Rabbit Weapon Mina) has gratuitous Fan Service-laden sequences. Complete with Gainaxing. Yes, magical Gainaxing. (Thus.)
 * Also, in the last episode, we find out that everyone else just sees them having a bright light surround them for about half a second, then they are done transforming.
 * Solty Rei showed a member of the RUC team suiting up with her Powered Armor in a fashion reminiscent of this trope, complete with a bit of bounce.
 * Subverted in Moetan. While Ink and Sumi's transformations fit the standard fare, Arks and Karts would be shown observing the naked transformations and drooling and Nosebleeding respectively, showing that the transformations take place in real time.
 * Kirby has a variety of transformation sequences, one for each ability. Most of them are cute and silly, but a few are darn cool.
 * Figure 17 has a short, less flashy sci-fi themed transformation sequence for Tsubasa and Hikaru. It appears to be mostly symbolic, however, because when we see the transformation occurring from "outside" it's just a dome of green light that envelopes the characters.
 * This is also implied to be a little bit negative, in fact -- the need for so much time to transform seems to be a symptom of Hikaru being a malfunctioning Figure. Normal figures are able to transform for combat fast enough to react to an attack; Tsubasa and Hikaru have to transform somewhere safe before getting involved.
 * Angel Blade features one or two of these. They never show a power down or what it looks like to the others in the area. Also since it's Hentai any implied nudity is thrown out the window as it's all plainly visible.
 * Parodied in ''Happy Lesson'. "Activate tutor transformation! Actually, I was wearing these underneath..."
 * Tengen Toppa Gurren Lagann features transformation scenes for each of the "stages" of the Gurren Lagann, featuring a specific background, and their awesomeness increases with the size of the resulting combination. The Chouginga Gurren Lagann scene deserves an special mention because half of it is about how epic sunglasses just got.
 * Actually subverted with the Gurren Lagann itself: when Kamina takes the Lagann and shoves it into Gurren's top, nothing happens. When they pull it off with a transformation sequence, it does! They spend the next episode practicing it -- or rather, Gurren keeps trying to crush Lagann with big-ass rocks to motivate Simon who keeps running away.
 * Itsudatte My Santa does this with the main character Mai getting an adult form, including gratuitous close-ups, including one after the transformation after the co-main character points out her added appeal. Is it any coincidence that it was created by Ken Akamatsu?
 * Some "soul resonances" in Soul Eater take a minute to charge up, noticeably Death the Kid's "Death Cannon" attack, which employs glowyness, dramatic angling, a countdown and a call. His definitely counts as a Transformation Sequence due to the fact they generally involve his guns molding themselves to his body and transforming his forearms into giant cannons.
 * Phoron's One Man Orchestra (before it was built into the bike) in Shinkyoku Soukai Polyphonica has a bit of an elaborate sequence for setting itself up in Crimson S.
 * Hellsing Every time Alucard is granted more of his powers, he recites an elaborate chant to invoke the release system.
 * In Saint Seiya, the Cloths (living suits of armor built to resemble the 88 Constellations) are typically carried around in enormous chests. When the Saint activates his Cloth, the chest shines spectacularly and bursts open (sometimes revealing a spectral construct shaped like Pegasus, a Dragon, a Swan, or whatever constellation the armor represents.) The Cloth within the chest reveals itself, assembled in the rough likeness of the creature from the constellation, before splitting into pieces that fly towards the wearer and clasp onto his body, one at a time. When it is complete, the Saint strikes a pose with the constellation shining in the background.
 * Kurokami has "Synchronization" which is accomplished through a shared transformation sequence of two people, such as This one
 * Pokémon evolutions can take up to thirty seconds on screen. Ash's  was an excellent example. However, after evolving, Pokémon can never change back.
 * The anime series Reideen features a bunch of more or less bishonen guys who transform into mecha-like armor which they may fuse into a Gundam-style mecha. The transformation includes light, they strip naked and then crystallize before becoming armored. After they transform back, they are actually naked and have to look for clothing or try to avoid being seen like that.
 * Natsuru Senou of Kämpfer periodically drops his (yes) Y-chromosome whenever another Kampfer is around in a short display of fan pleasing goodness (at least for the first few times).
 * The second season of Darker Than Black has a Contractor whose power is the ability to summon a gigantic antitank rifle, which involves a sequence, apparently in real time, in which she floats up into the air and the barrel of the gun comes out of her necklace. Given the show's habit of deconstructing every trope it gets its claws into, the fandom is already taking bets on how long it's going to be until she gets attacked in the middle of it.
 * And was entirely baffled when she didn't. Not even once for the whole season.
 * When Erza in Fairy Tail changes her magical armor in mid battle, all the mooks stop what they're doing to ogle her.
 * This is actually something of a subversion. In the manga it is noted that her transformations (actually just exchanging armor, called 'ex-quipping'), is performed astonishingly fast, to the point that it can be used practically in battle. Each transformation is assumed to take less than a second, just long enough for the opponent to go "Ooh, clothes vanishing from Hot Chick With a Sword!" before she's re-dressed in magical armor that lets her kick thirty people's asses at once without even trying.
 * The anime, however, gives her a traditional-style Transformation Sequence which, combined with the over-use of Stock Footage and Instant Runes, and the lack of blood from what should be gaping sword-wounds, makes it significantly less popular than the very-awesome manga.
 * Thankfully, the anime got the hint and got rid of the Transformation Sequence.
 * The anime version of Chrono Crusade gave Chrono a transformation sequence when Rosette unseals the watch and unleashes his true form, complete with his clothes ripping as he grows in size. In the manga, the transformation is never really seen, but seems to be instant.
 * Somewhat spoofed in the manhwa Dorothy of Oz. When Mara activates the boots, her clothes are actually ripped apart and reformed into her witch's outfit, meaning that everyone sees her naked. And yes, the reason why nobody interrupts the sequence is that they're ogling her.
 * Seto no Hanayome has San and Luna transforming into their Idol Singer mode in order to stop a Yakuza War. Nagasumi hangs a lampshade on it.
 * Later on, the Class Representative (by far the most reserved person on the show) spontaneously transforms into 'Yes Amazoness' an amazon warrior as a cover when she accidently confesses her love to San.
 * Nanatsuiro Drops has a strange case in that they wait until the ninth episode to give them to the two Magical Girls, and then we never see them again after that.
 * Hell Girl's Ai Enma has one of these nearly Once an Episode (in the first season, anyway.) However, it's not very traditional.
 * Heroman gives male protagonist Joey one of these, though all that's really changing is the gauntlet. It has a rather Magical Girl vibe which isn't helped by Joey's excessively girly appearance. Heroman himself has a version of one of these early on, where he marches toward the enemy growing larger with each step, but he stops using it after the first couple of goes.
 * In Digimon Data Squad, Lilymon practically strips to become Rosemon... Hey, we're talking about a digimon whose second favorite move is "Forbidden Temptation".
 * Dragonball Z is the shounen version of this trope. Many of the characters have powered up forms and minor to major transformation sequences.
 * All of the Saiyajin who still have their tails can transform into monstrous 50-foot-tall apes when they see a full moon, and most of the Saiyajin featured in the series also master lesser form changes, the first just being developing a glowing aura, and their hair turning gold and standing straight up. This is one of the early examples of a super mode.
 * Inverted form of monstrous change for a couple of villains, when Frieza and Buu have power ups that leave them in a smaller, cuter, but more powerful form. Both Frieza & Cell are also examples of a Bishounen Line.
 * Magic Knight Rayearth embodies this trope. Hikaru, Umi, & Fuu all do this, complete with gratuitous Barbie Doll Anatomy.
 * Despite being from a Super Robot anime, Takuto's transformation into the Galactic Pretty Boy (just go with it) in Star Driver may as well have been taken from Sailor Moon.
 * The Mahou Sensei Negima OVA's give both Asuna and Konoka a Magical Girl-style transformation sequence when they summon their Artifacts. This is purely stylistic, though, as all other Artifact summonings (even when a clothes change is involved) are shown to be instantaneous.
 * The Extra OVA "Magical Girl Yue" takes the chance to parody this. Yue gets a transformations sequence to stylistically summon... normal underwear and clothes. (Plus a Robe and Wizard Hat )
 * Kamichama Karin, as you'd expect. Only two transformations (Karin's main one and Kirio's) actually use Stock Footage, though - Kazune usually skips the sequence and any other transformations are only shown one or twice. The series also averts Out-of-Clothes Experience for the non-stock ones, instead just having the character change out of whatever they were wearing at the time directly to their transformed state.
 * Panty and Stocking With Garterbelt, like the Soul Eater example above, only has the weapons change (although the users do change as well, it's temporary and they change back into their normal clothes shortly after the sequence is done), though it's joined by a sparkly, disco-like enviroinment, switching out of its "normal" Western-style animation and going into traditional anime style... and bringing with it tons of Fan Service and pole dancing.
 * Devil Hunter Yohko was an early entrant in the Magical Girl genre, with it's highly fanservicely sequence. Her younger sidekick's sequence was quicker, and even when 'nude' was done with less fanservice. On the otherhand, Yohko's identical twin cousin's sequence was just as much as Yohko's, with a dark edge.
 * Puella Magi Madoka Magica. It's a Magical Girl series, if an atypical example.
 * Interestingly, the sequences are atypical as well; the sequences are very brief, very quickly put on all parts of the outfit rather than concentrate on each part individually (Mami's was probably the closest to one that did the latter), and the audience only gets to see each one once or twice in the entire series. When they do appear twice, they are animated differently according to the situation, averting Stock Footage. The majority of the "transformations" just end up being the girl briefly glowing and reappearing with new clothes, what it would probably look like in real-time. And
 * Full Moon wo Sagashite gives Mitsuki one when she turns into Full Moon. A rather simplistic sequence is used for the first half of the series, but a more elaborate looking, Magical Girl-type one was used in the second half. Meroko also gets a short sequence when she shapeshifts.
 * Black Jack, oddly enough. In the manga he washes up and puts on his scrubs like any normal surgeon. In the anime there's a fanfare and a light show and what looks for all the world like a Magical Girl transformation. And he's just Badass enough to make it look good.
 * Alma Tandoji of Sacred Seven, he can only do this when Ruri is near him. He then would take a page of Mega Man X which he uses a similar get up for his battle suit.
 * Revolutionary Girl Utena features this. Oddly, the one transforming isn't in charge of the transformation.
 * Mechanical Transformations are surprisingly averted most of the time in Tiger and Bunny. Despite it being a Mecha Superhero action anime with its fare share of plot-less moments, we rarely (with the exception of episode 5, which has a pretty standard one) see the characters getting into their battle outfits. Super Mode transformations happen so quickly that they aren't really a 'sequence', and are usually symbolized by a slight (by anime standards, at least) Battle Aura and glowing eyes. Kotetsu, being the protagonist, gets a couple of Growing Muscles Sequences just for the heck of it.
 * Mononoke features an interesting variation: rather than shifting between forms, the Medicine Seller appears to actually switch places with the "magical" version of himself. During the transition the Medicine Seller's tattoos and clothing patterns dissappear, and his counterpart receives them. There's also a brief moment in one episode where the two versions of the character interact, as the "normal" Medicine Seller hands over a small mirror to his counterpart from off screen to help in a fight.
 * Transformation sequences in Okusama wa Mahou Shoujo are fairly long, but used rarely. Like many other examples, they're instant in real time.
 * In High School DXD, Issei's transformation sequence into his Balance Breaker does take at least 15 seconds in the anime. The first time he gets to use it in the anime is at the final episode though.
 * In the anime of Monochrome Factor, Akira, Kengo, Aya, and Kou all get one.
 * In the anime of Monochrome Factor, Akira, Kengo, Aya, and Kou all get one.

Comic Books

 * The Clown from Spawn becoming the terrifying devil Violator. The detailed transformation in the movie is particularly disturbing.
 * Iron Man occasionally has one, depending on the title and era (for instance, it's very rare to see him activate the suit in an Avengers comic). The most typical one involves assembling the armor from a briefcase. This was abused a bit during the late 90s and early 2000s when every new writer on the Iron Man title introduced their new, super-advanced armor technology, like the SKIN armor, Tin Man and Ablative armor.

Fan Works

 * In WanderingWordsmith's Thawing Permafrost, Pandora the Shikigami explodes into a weird white goo, then reforms into the commanded form if it can manage it; otherwise, it just flips back to its normal form and collapses, exhausted.
 * Kuso Miso Technique's Michishita Masaki has one in this fanvideo into his powerful, naked form.

Film

 * An American Werewolf in London and The Howling both have werewolf transformation sequences of the most painful and not to mention terrifying kind you can imagine.
 * Underworld and Underworld: Evolution, with static vampires (except for the main vamp boss with the somewhat typical beastly demon-form) but human-werewolf transformations, and their werewolves have inverted knees digitigrade legs.
 * Not much outright transformation was shown in the first movie, the most notable sequence being one shot where two lycans change back, as well as one sequence where a character had an aborted change. The second film had some decent shots of man-to-wolf changes, but they went quick because they were Mooks.
 * There are a number of these in Van Helsing, most notably the werewolves who transform by ripping their skin off.
 * Fright Night had something like this with Evil Ed turning back into a human from being a wolf, and the vampires have 3 stages of transformation.
 * The 80s remake of The Fly, though that happens by degrees over a long period of time. They're also completely terrifying.
 * Ghostbusters has the scene where Dana and Louis turn into Terror dogs; it's quite a disturbing process, though.
 * Also, the sequence where a ghost librarian turns into a hideous ghoul.
 * The 90s remake of The Nutty Professor had some surprisingly gruesome ones with plenty of Body Horror.
 * And the original has Jerry Lewis going through some grotesque transformations quite out of the tone of the rest of the movie.
 * Videodrome is just plain weird in general but the transformation parts are even weirder.
 * Steven Chow's God of Cookery takes this to absurdity with Magical Chef Transformation Scenes. A character (not the lead) takes a power pose, his clothes fly off in all directions and underneath he is already dressed as a chef, all that is required is that he put the trademark hat on.
 * Gremlins has a very important rule: "Don't feed them after midnight." If you do, the Mogwai goes into a slimy cocoon and mutates into a hideous monster. Unfortunately in the movie somebody makes that mistake as well as getting them wet (causing them to multiply, which looks incredibly painful). There are several gruesome gremlin-related transformations in the sequel, including those involving a bat, spider, fruit, electricity, and even a woman!
 * The Witches of Eastwick has the final scene in which the three witches mix up the body parts of a voodoo doll that resembles the main antagonist Daryl (Jack Nicholson) who at first turns into a giant, but then turns into a worm-like thing.
 * The Jekyll and Hyde transformations from The League of Extraordinary Gentlemen.
 * In Mary Reilly, John Malkovich undergoes one of the most gruesome and spectacular Jekyll / Hyde transformations ever committed to screen. Then, afterward, he looks exactly the same.
 * Pretty much every adaptation of the Jekyll and Hyde story, though the transformations are often fairly restrained in the less campy versions.
 * The 1932 film is not very campy, and its transformation sequence was at the time a major breakthrough in special effects.
 * The musical does an interesting variation: Jekyll changes into Hyde by... turning his head to the left, hunching a bit, and having the lighting change. However, if the actor is good enough, it works, especially at the end when he's doing a duet with himself and changing back constantly.
 * The A Nightmare On Elm Street series has quite a few of these. For instance, in Dream Master, fitness girl Debbie is turned into a cockroach and then trapped in a roach motel by Freddy Krueger.
 * Beauty and The Beast has a famous transformation sequence the inverse of a monstrous transformation.
 * Ditto Eustace transformation from dragon to boy in the Voyage of the Dawn Treader film.
 * The sequence at the end of the first Shrek is a double subversion as 1) she is already a monster and 2) she doesn't actually transform. It's also a Shout Out to the scene in Beauty and The Beast.
 * The Marvel Cinematic Universe plays around this:
 * Tony Stark puts on his suit different ways:
 * The Mark II and III armors were placed on him by JARVIS-conrtrolled droid arms, stored either in a safe platform inside his garage or in his helipad. The Mark IV and VI armor are also put on this way.
 * The Mark V travel armor, also known as the "briefcase suit" is what you would imagine it to be, with a button pushed for its handles to appear. Tony then places it across his chest/arc reactor and it assembles neatly around him.
 * The Mark VII is probably the most egregious: Tony would wear tracers on his wrists, with the armor (in a large capsule shape) summoned via voice-activation to latch onto the tracers and form around his body. It is practically useful on-the-go...
 * Bruce Banner, being who he is, can (a) be triggered into becoming the Hulk under stressful conditions or (b) lets it out freely. Whatever is happening could be determined whether he is struggling or he seamlessly transforms.
 * Thor, while spending almost an eternity wearing his Asgardian dress armor,  Mjolnir flies to him and strikes him with lightning, forming his traditional armor. His helmet, apparently, is a separate piece and not always worn.

Literature
"Very slowly things began to happen..."
 * Animorphs: Characters who morphed had to wear tight clothing or risk becoming naked when they remorphed. The latter only occurred once. The books made it quite clear that morphing almost never happened the same way twice, and was usually highly disgusting unless the morpher had an unusual talent for it (as did Cassie).
 * In the Discworld series, both vampires and werewolves can transform, vampires into either a swarm of bats or one really big bat. Not much detail is given to werewolf transformations, but there is at one point a fight between two of them where they're both in a constant state of flux between forms. Angua, the werewolf on the watch and Captain Carrot's girlfriend, is stated to be perfectly comfortable with him seeing her naked in either form, but doesn't want him to see her mid-change.
 * Gaspode is surprised when he sees Angua change -- expecting the usual horror sequence, he instead describes it more like "A full-body sneeze."
 * In Winni Allfours, the protagonist is a girl who wants a pony. When that's denied to her, she chooses to turn herself into a pony. Two whole pages of the small book are dedicated to showing her change from little girl to tubby little pony.

Live Action TV
"Ziggy: Sometimes when I morph, I can't help but notice this gigantic explosion right behind me for no apparent reason."
 * The many and varied Ultraman series usually involve a man-to-giant-alien-robot-thing transformation.
 * Pretty Guardian Sailor Moon (2003-2004) showcased several different transformations managed via digital effects. The results ranged from Moon's clumsy and cringeworthy transform (the first created by the production team) to Dark Mercury's showstopper (the final transform created, after the team had gained months of experience with their tools).
 * As with its animated counterpart, we see only one or two instances of de-transformation, and these also appear to be simple acts of will.
 * Additionally, we get to see one transformation -- Minako to Venus -- from the "outside", as an eyewitness on the scene would. Instead of all the fancy effects, it's an instantaneous, blink-and-you'll-miss-it change that she performs while running, thus validating years of fan speculation.
 * A later sequence, however, has Ami transforming. Unlike Minako, however, she gets a blue glowy thing.
 * They also fondly parodied the trope in one of the supplemental shorts: Mamoru becomes "Tuxedo Mask" just by putting on a tuxedo, top hat and mask, but the one time he does it on camera, it gets all the same fancy shots, edits, and sound effects as the girls' magical transformations.
 * Many, many, many Kamen Rider characters had this... until 1989. Actual sequences were common in the Showa era; even the enemies had transformation sequences, even if they amounted to little more than the camera zooming in on them, blurring a bit, and revealing the monster from its disguise. For the revival era (Kamen Rider Kuuga and onward) they were mostly phased out in favor of transformation special effects done on the fly. Just about the only Heisei series to use honest-to-goodness Transformation Sequences is Kiva, and only then for form changes.
 * In several early Kamen Riders, the pre-change gestures were as epic as the sequences (also not so much nowadays; you may get the Transformation Trinket held in the air during the call of "Henshin.") and enemies sometimes stopped the henshin gestures by attacking during the middle of the gesture, or setting traps that would halt them.
 * Similarly, Kamen Rider Decade has a scene where Yuusuke/Kuuga attempts to transform in order to fight Kaitou/Diend, only to be interrupted mid-pose when Kaitou points his Transformation Trinket, a gun, at Yuusuke's face.
 * The "transformation chivalry" was humorously acknowledged in the first Kamen Rider Den-O movie: the Big Bad's minions attack Ryotaro as he attempts to transform, causing Momotaros to angrily shout "Bastards! You're not allowed to interrupt the transformation sequence!"
 * Brutally subverted in Kamen Rider Double when the Arms Dopant fires a goo "bullet" that plugs up Shotaro's belt, preventing him from transforming.
 * The "chivalry" aspect was parodied in the net-exclusive comedy shorts produced for Double. Kirihiko asks Isaka why he didn't attack when Accel transformed into his Super Mode, Trial. Isaka responds that he was "obeying traffic laws".
 * The Darker and Edgier Heisei series like Kamen Rider Blade and Kamen Rider Faiz tended to have transformation chivalry less frequently, with characters often walking or even fighting in mid-transformation. Debut appearances always played it straight, though; probably best illustrated in the first episode of Blade, where Kazuma's belt orbits his body several times, trailing a "tail" of cards, before finally settling in place around his waist.
 * Transformation chivalry is enforced in some series by the Sphere of Power or other transformation effects being absolutely impenetrable, deflecting attacks and painfully repelling villains who attack in midmorph.
 * Kamen Rider Decade and its Super Sentai counterpart Kaizoku Sentai Gokaiger both feature variations on the theme, since both those shows focus on heroes who can use the powers of their precursors. When Decade changes into a past Rider, it's represented by the usual Transformation Special Effect, except that it's happening to a suited-up Decade rather than an untransformed human as normal. For the Gokaigers, the initial transformation into Gokaigers is a straight Transformation Sequence while their changes into past teams are more simple (usually: team emblem flies out of their Transformation Trinket, lands on their body, and their suit changes in a flash of light), except in the special episodes where they unlock a past team's true power by coming to understand that team; in these cases, they get honest-to-goodness Transformation Sequences based on the originals.
 * Also, these series feature old-school characters with modern effects, and in Kamen Rider terms, modern rules, which means we get to see what several transformation sequences look like in "real life." Kamen Rider Black and Kamen Rider Black RX get to change side-by-side with real-space versions of their classic sequences, and it is awesome. Also, in The Movie, we get to see Shadow Moon's transformation for the first time ever (as in Kamen Rider Black proper, he was in this translucent cocoon-thing until emerging in Shadow Moon form once his powers matured.) Interestingly, Kamen Rider Kiva still has form change sequences when Kiva's doing them (Decade's Kiva changes, like all his changes, are real-space.)
 * Gokaiger's past Ranger powers are the powers of the actual past sentai heroes, meaning few returning characters get to change and fight, so we don't get to see a lot of new old morphs. However, we do get one for  Chojin Sentai Jetman, because he is   However, when the Gokaigers do the above-mentioned focus episode transformation sequences, we get some idea of what the old sequences would look like if made today.
 * Power Rangers: In the earlier seasons, the usage of Stock Footage became quickly grating, as the rangers would look the same at the beginning of the sequence, regardless of what clothes they'd been wearing beforehand or changes in their hairstyle. In later seasons, it became standard to use clever tricks to downplay this; many seasons have the Rangers wearing uniforms or otherwise having a Limited Wardrobe before the (full) sequence begins. In several other seasons, the sequence is cut such that their pre-transformation clothing is hidden during the sequence using close-ups and visual effects.
 * Occasionally, a shorter Stock Footage-free Transformation Sequence was used instead, which, with a very few exceptions, used a much blander and more generic special effect. As seen in "Countdown to Destruction" as well as several other times throughout the various series, the actual transformation is in fact instantaneous and consists of nothing more than a small explosion or just some glowing masking the shift -- the drawn-out sequence is purely for the audience's amusement. We see this in action for the first time in Power Rangers ZEO, where three Rangers dramatically run up and change in-scene. By now you're used to it, several in-scene changes in an episode and the "real morph" saved for the big final battle with the monster, but back then, this was after four years, at a time when it just wasn't done, and there was a lot of HSQ in it.
 * The Mighty Morphin Power Rangers transformation sequences weren't very elaborate... so in "Once a Ranger" a new, snazzier sequence was made for Adam (the second MMPR Black Ranger) so he wouldn't be the only one without.
 * Adam's old morph was Screwed By the Lawyers. At the time, Disney had rights issues with MMPR, so they were forced to scrap the old sequence entirely (with an unfortunately generic song played along with it, as they couldn't get the MMPR music either).
 * The record for most sequences in one season - MMPR season three. We've got civilian to ninja suit, civilian to Ranger (all new ones!), ninja suit to Ranger, Rangers to Metallic Armor mode, and then the five Alien Rangers.
 * Then there's Justin's transformations in Power Rangers Turbo, which have a little bit added compared to the others to show him growing to adult size.
 * Like everything else in Power Rangers, nothing is safe from lampshading by RPM. Not even morph sequences.


 * Taken to its logical extreme by Flynn in the same episode, where
 * Surprisingly subverted in Mighty Morphin Power Rangers the Movie. In the time it takes for the rangers to suit up, the bad guys flee the scene.
 * Power Rangers gets extra trope mileage thanks to the Humongous Mecha. Entrance, transformation and combination for a triple trope score combo!
 * And it is also seen in Saban's Masked Rider. It's brand new, as Kamen Rider Black RX's change was nothing but the belt appearing and getting glowy, at which point the transformed Black RX would be seen in real-space (in fact, several old Riders' transformation sequences are elaborate belt-summoning and activations without showing the actual suit formation.) but it looks very much like something you'd see in old-school KR. The form changes are RX stock. Also, Robo Rider gets to transform onscreen (no sequence) where Shadow Moon didn't.
 * Big Bad Beetleborgs had the drawn characters leap from the comic book which opens up, then the kids, drawn up as a comic book page, standing side by side. The armor appears slowly, then the three Beetleborgs step forth, with the Koosh Explosions turning into real flashes of yellow light as the Borgs go from comic-booky to real life Metal Heroes. Later in the series, the pictures of the kids morph their chosen suits.
 * VR Troopers gets them, with the VRT actors' faces beneath what's mostly the Metal Heroes' original Japanese transformations. Holding up the Virtualizer pendants is new.
 * Speaking of the Metal Heroes franchise, the Space Sheriff Trilogy makes it perfectly clear that the Transformation Sequence is for our benefit. After an instant "flash of light, morphed now!" change, we'd get "[Hero name] takes 0.0[small number] seconds to equip his suit. Let's take another look at the [morph command] process." and then the changing sequence, which is a flashback.
 * Kaizoku Sentai Gokaiger vs. Space Sheriff Gavan the Movie shows that the Gokaigers actually morph even faster than a Space Sheriff.
 * Superhuman Samurai Syber Squad gets a hybrid of the real-space scenes and the stock footage sequences. Sam striking the 'power chord' on his guitar is half new footage (constant angle-changing for drama. The alternate angle is stock footage.) as is his transforming into energy and flying into the computer. The energy entering the Servo form on the screen and Servo flying into action is stock footage, as well as Servo's 'decompressing' into his proper size. (The original series is a Spiritual Successor of the Ultra Series, so decompression replaces the heroic Make My Monster Grow to building size.)
 * Kamen Rider Dragon Knight gets a much fancier transformation than the Kamen Rider Ryuki original did, complete with the monster-repelling Sphere of Power seen in more recent Japanese KR series. No stock footage sequence, though - it's all real-space, like modern KR. However, one small part is stock footage: the closeup of the Advent Deck being inserted and spinning is the same every time. Of course, that didn't save 'em much time and money, as there were thirteen Riders and one Advent Master, and we only saw some characters change once.
 * An earlier Filmation production of Shazam! from the 1970s had the magic-word-and-lightning transformation between Billy Batson and Captain Marvel. It was usually paired with a similar show, Isis, which had its own transformation sequence.
 * In a case of typical Filmation cheapness, the detransform from Captain Marvel back to Billy was handled by simply running the transform footage backwards, even though that meant the sequence ended with a lightning bolt unstriking Billy.
 * In the 1970s The Incredible Hulk series, David Banner (Bill Bixby) would transform into The Hulk (Lou Ferrigno) using the same sequence of events, involving multiple close-ups of Bill wearing coloured contacts, then the his skin turning green, the shirt tearing on his back and then a full shot of the Hulk, whipping off the remnants of the shirt.
 * The 1970s Wonder Woman series actually had two different Tranformation Sequences. In the first season it was essentially a slow-motion montage of Lynda Carter spinning in place in different stages of the change. Starting in the second season, though, a much shorter and more dramatic sequence was used where Carter would spin, there would be an optical of an explosion over her, and then she would appear in costume. The latter has become subject to much parody. (As well as an homage in an episode of Justice League Unlimited)
 * It should be noted that the original transformation sequence was an almost erotic striptease-like affair. Apparently it was too expensive to film, and the explosion-transformation was used as a money saving device.
 * The Twilight Zone pulled off an impressive transformation scene despite limited special effects in The Howling Man. A man walks down a pillar-lined hallway as the camera follows alongside him. As he passes behind each pillar, he gets more and more demonic (ending with a cliche horns and tail Satan). It's cut so that it appears to be one long take, but there's no effects on screen at any point.
 * This technique is also used for the Wolf Man transformation in the 1935 film Werewolf of London.
 * Masters of low-budget kid shows, Sid and Marty Krofft had a few of these. "Activate Electra-Change!" turned Lori and Judy into Electra-Woman and Dyna-Girl, and a magic horn turned the junky Schlep Car into Wonderbug.
 * Wonderbug's sequence was actually cheaper-looking during the actual show than it was in the opening, which was quite a feat.
 * The Mystic Knights of Tir Na Nog, the ancient Irish Power Rangers.
 * Manimal, starring Simon MacCorkindale. Though he could transform into any animal, there were transformation sequences only for three animals.
 * And they never explained why he always returned to human form fully clothed despite the transformation sequence's clear depiction of his clothes ripping.
 * George's werewolf transformation in Being Human, heavily influenced by An American Werewolf in London.
 * "POWER ON!" By pressing the team's distinctive phoenix insignia, Captain Power and his cohorts would activate the Power Suits which would transform from "patterned longjohns" worn under their uniforms, into actual plate armor with weaponry and personalized devices. Heavy damage to the Power Suit would make them fade back into their inactive shape.
 * Kitchen Nightmares -- in the UK show at least -- has Gordon Ramsay "transform" from normal everyman into Super-Badass-Chef-Ready-to-Save-the-Fucking-Day by stripping out of his civilian clothes into a brand-spanking new chef's coat. Estrogen rises predictably.
 * KITT in the last season of Knight Rider and KI 3 T in the 2008 TV movie and show.

Music Videos

 * The first segment of Michael Jackson's Thriller has Michael transforming into a werepanther.
 * There's also Michael turning into an Optimus Prime-esque Transformer at the end of Moonwalker.
 * Weird Al Yankovic undergoes a transformation sequence at the start of his video "Fat" that fortunately does not strip him nude in the process.
 * Similarly enough, the music video for "Right Here, Right Now" has a transformation sequence based on the theory of evolution.

Video Games
"Marius: What I saw next was not meant for mortal eyes!"
 * Princess Waltz has a transformation sequence Magical Girl style, but despite it being a hentai game, the fanservice level isn't worse than you average Sailor Moon episode (albeit minus the glowing Barbie Doll Anatomy effect.
 * Sonic the Hedgehog regularly delves into this trope with the titular character's Eleventh Hour Super Powers. The most notable are Super Sonic and most related transformations, and Excalibur Sonic.
 * Subverted in Disgaea, when Etna shoots two Sentai members during a transformation sequence because, hey, they were wide open during it. Turns out that was the dumbest thing she could have done...
 * Then again Disgaea 3 and the PSP remake of Disgaea 2 plays this straight with the "magichange" feature (which allows a monster type unit to "merge" with a humanoid unit by acting as a weapon for them), although only the monster unit transforms.
 * One of the combination attack animations in Disgaea 4 a Promise Unforgotten has the participants put on a simplistic, multi-person centipede costume, accompanied by dramatic visuals, sound effects, and camera angles.
 * Also features a brief one when monsters combine for the size increasing type of transformation.
 * Parodied in Silent Hill 3 (Of all places...) when Heather equips her ridiculous Princess Heart outfit, triggering a lengthy transformation.
 * The early Mario and Castlevania games actually pause the action around the player character while he's transforming, though the change in form was fairly instantaneous and without frills otherwise.
 * The SRX from Super Robot Wars has an impressive combinations transformation which has its own theme called "Variable Formation".
 * The Breath of Fire series is the king of this trope for video games, since the main character of each game (all named Ryu) can transform into a dragon, with a more elaborate sequence in each game. Furthermore, in the first and third games, a second character has a transformation sequence (Karn in Bo F 1, and his Fusions; Rei in Bo F 3, and his Weretiger transformation), and the fourth game's antagonist, Fou-Lu, is playable and can also transform into a dragon in a sequence largely identical to Ryuu's.
 * Saga Frontier: Red had one but nobody could see it because he needed to maintain his Secret Identity. But a good Secret Identity Change Trick (Power Outage, Mecs only in party, Characters stunned/blinded) allows him to go Alkaiser no problem.
 * The Legend of Dragoon has individual anime-like transformations for every single playable character in the game, as they turn into their Dragoon forms. One villain also gets a mid-battle transformation into a Dragoon with his own sequence. Dart, the main character, gets a second Dragoon form late in the game with an even more over-the-top sequence.
 * Luckily there was a menu option to replace the sequence with a much shorter "Normal form * Flash* Dragoon form" sequence.
 * But you still got the full transformation sequence of the character who initiated the "transform all" Special command.
 * Saiyuki: The Journey West features characters who can transform into monsters. Each one has an elaborate transformation sequence and an equally elaborate reversion sequence. Furthermore, there's two more sequences for transformation and reversion used in cutscenes (even though they otherwise use the same sprites!)
 * More minor transformation sequences are used in Final Fantasy VII (Vincent's Limit Break) and Wild Arms 2 (Ashley's transformation into Knight Blazer). These pretty much are of the "original character fades out, new form fades in" variety rather than the flashy sequences mentioned above, though.
 * This trope is arguably the entire point of Final Fantasy X 2. Luckily, there's an option to shorten or turn off the transformation sequences after the first time the girls have changed into their new Dresspheres.
 * The character of MOMO in Xenosaga gets powerups that can be used once per fight that include transformation sequences.
 * Mega Man ZX "Model X! Model Z! Megamerge!"
 * Every single villain and hero also transform in the Star Force games, though admittedly usually everyone except for Geo gets theirs shortened to a quick fade to white and back.
 * The Tekken series has quite a few. Including Devil Jin's ending from the fifth game and Ogre's transformation into True Ogre in Tekken 3.
 * Transformation sequences were an oft-requested feature in City of Heroes, and a small set of four costume-change emotes are now available as part of the Magic Booster Pack (released in Spring 2009). Another half-dozen or so became available with Issue 15, and each of the origin-themed expansion packs adds one or two as well. They run the gamut from reminding you of Wonder Woman ("Spin") to Captain Marvel ("Lightning") to being reminiscent of the arrival of time travelers in the various Terminator movies ("Energy Morph").
 * Kheldians and Nictus, the game's resident body-stealing shape-shifting aliens, follow this trope to a T. Switching into their forms involves a moment of concentration and a big, screen-shaking flash of Kheldian/Nictus energy, whereas switching back just makes the human silently pop into existence where the alien used to be.
 * Super Smash Bros. Melee has a relatively quick transformation sequence between Zelda and Sheik. This is lengthened in Brawl because of loading, and Pokémon Trainer goes through a similar "transformation" when switching Pokémon, but the character transforming cannot be damaged or intercepted from the time the sequence starts to when it ends. There is still a lag period at the end, though.
 * Altered Beast has a momentary pause before buffing up when one of the magical floating steroid balls is collected, followed after a third time by a transformation sequence to make you into a werewolf, dragon, or giant cuddly bear with halitosis. The werewolf one is particularly detailed.
 * The Japan- and Europe-only PS 2 game Project Altered Beast has horrifying transformations. The player takes the role of a "Genome Cyborg" investigating a town that has been overrun with "Genome Mist" transforming all its inhabitants into horrifying monstrosities. The main character appears as a human but has the ability to take various forms. No matter which form is chosen, it is accompanied by a gruesome CGI video detailing every aspect of the transformation as limbs blow up and regrow and various organs are mutilated and reshaped, with no limit on the amount of gore.
 * Diablo 2: In the cutscene before Act IV narrated by Marius, he has the misfortune to witness The Wanderer's horrific transformation into Diablo. Spikes burst out from his back, his face distorts horribly, and it ends with Diablo casting aside what's left of his human shell like a dirty rag.


 * Pokémon evolution features the creature fading into its outline, and then the outline shifting into the new evolution, before fading back in. You can glitch this process in the first game, resulting in a near-endless stream of (impossible) evolutions.
 * The Legend of Zelda Majoras Mask has earned its fame as the darkest of the Zelda titles partially due to the transformation scenes, which involve Link gasping and cringing to the background transformation sound effects, culminating in a scream as the sequence finishes. Skippable by pressing a button, but only after the first time. Transforming back triggers a short scene involving a halo effect around his head as he pulls the mask off, reappearing as human.
 * Gitaroo Man's can be seen here about a minute into the video. His transformation is sort of rushed in further levels, though.
 * In Mass Effect 2, when Harbinger engages his Villain Override and takes control of a Collector, the Collector's body goes through one of these. Note that he is not invulnerable during the transformation sequence, allowing a quick-witted player to whittle down his shields and armor before he starts attacking. The transformation sequence elevating him above most structures serving as cover certainly helps getting a few good shots in.
 * Prototype: Alex Mercer goes through a lot of morphing, but acquiring a power during a cutscene, the camera zooms in for a sequence with writhing sinews of biomass in the full spectrum of color from black to grey consuming him before he emerges with his new Red Right Hand.
 * You can also do the long version of the sequence at any time by holding the D-pad for the quick-change instead of just pressing it. This lets you see the sequence for powers you acquire as upgrades like muscle mass, whipfist, and the vision powers.
 * Command and Conquer Red Alert 3 has the Empire's Tengu launching into a backflip and transforming mid-air when switching between mecha and jet forms. In-game.
 * To a smaller extent, the Striker VX does it as well. The intro even shows it extending two spindly legs just prior to landing then folding back it's propeller before firing off-screen.
 * Or for that matter, every single amphibious unit in the game does a Transformation Sequence when going from land to water or the opposite; from Allied Prospectors expanding an air cushion to Soviet Stingrays extending six legs and climbing ashore, Spider Tank style.
 * Ar Tonelico 3 did this in a reverse effect. Reyvateils remove their clothes during their zoom-in transformation sequences. Strangely enough, they reequip their clothes in a flash when they begin using their ultimate attacks.
 * Carbuncle from Puyo Puyo, in this commercial, does the usual intro... right before Carbuncle transforms into a handheld with Carbuncle himself inside it.

Webcomics
"Riley: You know, by the time you transform, the world could have already been destroyed.
 * In Holiday Wars, April Fools' Day is a shapeshifter and in between forms he turns into a giant glob resembling an ink blot, as seen in this strip.
 * Played straight and parodied twice in the GOFOTRON arc of Sluggy Freelance.
 * Played straight in this Dresden Codak comic
 * In Union of Heroes there is an animated transformation sequence of Munin changing from his human to his raven form and flying away.
 * Alex in the webcomic Angel Moxie has a sequence, though it only occurs a couple of times the second time it crops up has a lampshade hanging.

Alex: It's my moment. Let me have it."


 * Later,.
 * Quite obviously gets quite a bit of use in El Goonish Shive. Here's one of the earliest examples, that even got a fan animation once!
 * Lampshaded in this Megatokyo strip.
 * Parodied in Head Trip.
 * Sexy Losers parodies the Sailor Moon example with... obvious results.
 * Sparkling Generation Valkyrie Yuuki, of course.
 * Xkcd: When he hears a cry for help, Sagan-Man whirls around and dons a cape.
 * Parodied (along with the idea with the idea that all lesbian characters must be stereotypically 'butch' and own loads of cats) in this Red String guest comic by Megan Gedris.
 * Mahou Shounen Fight features one here for protagonist Mike Smith; note that he isn't stripped completely naked as he keeps his Mantis Man underwear on.
 * Much to her horror, Tohsaka gets one in Fate/hollow ataraxia thanks to the Kaleidostick.
 * Parodied in Kid Radd. "Magical Maid Robo Sheena!"

Web Original

 * In Arcana Magi Zero, when Alysia Perez calls for Saga and Megumi Miyazaki calls for Fable, their magic circles would go through their bodies forming their magical outfits and armor.
 * Yuki Shimizu in The Impossible Man has a Transformation Sequence off scene. The plausible reason was to hide her identity from everyone, even her co-workers. Unfortunately her co-workers already figured out her secret identity and she know its too, but she still goes off scene in their presence when there are no vilains around to transform.
 * Linkara's had a few Power Rangers styled ones in Atop the Fourth Wall', and then there's Spoony turning into Dr Insano in Kickassia''

Western Animation
"Jonathan: (after the band changes back) Alright! Great job, gang!
 * W.I.T.C.H.
 * Winx Club and its Spin-Off Pop Pixie
 * Centurions -- About a 15-second sequence, as all the various parts of the chosen weapons system would beam in and attach to the hero's exo-frame, ending with the helmet rudely clamping on to the head. Often showed all three heroes transforming back-to-back, and had the same trigger phrase: "Power Xtreme!" (Later episodes of the show usually skipped the stock footage, and just showed the pieces appearing and attaching all at once. The two Sixth Rangers added later never even got the stock footage versions).
 * He-Man and The Masters of The Universe, when it was a Filmation production, got maximum mileage out of Prince Adam's transformation into He-Man with lots of digital pyrotechnics for very little physical change. (He-Man looked identical to Adam except for a tan and a deeper voice; how nobody put two and two together is baffling.) If Cringer was present, his transformation into Battle Cat would further pad the scene.
 * He-Man's twin sister She Ra had a similar sequence, but it was actually longer (and more sparkly). Like Cringer becoming Battle-Cat, She-Ra's talking horse Spirit would become the winged unicorn Swiftwind.
 * In contrast, in the more recent 2004 series, He-Man's transformation takes mere seconds and he looks almost nothing like Prince Adam, though it retains its predecessor's Stock Footage ability to be used time and time again.
 * Spoofed in an episode of Invader Zim. Gir begins a Transformation Sequence, complete with music, lights, and midair spinning... and then simply steps into his dog costume and zips it up.
 * Curiously, the original appearance of the Transformers in the West did not include overt transformation sequences. The characters would make the switch between robot and vehicle/device forms wherever they were standing in complete continuity with the scene (although they always transformed the exact same way). This is more cultural than cost; newer series such as the shows of the Unicron Trilogy, which were actual anime, frequently featured such scenes, and the Japanese Alternate Continuity third season of Generation 1 featured transformation sequences for new characters only (old ones kept scene continuity). Transformers Animated is generally in-scene but faster than G1, unless the bot in question is about to do something important (e. g., Megatron transforming for the first time after being rebuilt and telling the Decepticons to "Transform and Rise Up").
 * 'Transformers Animated also had the Autobots using Japan-esque transformation sequences in the final episode, mostly for dramatic effect.
 * Magical Girl-esque variant with  in "Transwarped".
 * Beast Wars didn't have the music and lights, but did consider them a free action, such as Cheetor going into robot mode while outrunning a fireball.
 * The were more or less free actions considering that many of them had forms that had the same parts for legs or otherwise the ability to fly. Rattrap shows this shortly after acquiring his transmetal form and used the momentum from his motorized wheels to transition into a flying leap so that he could aim a few gunshots at Megatron without stopping.
 * Rescue Bots is probably the first western Transformers series to use transformation sequences on a regular basis.
 * Ben 10 has ten unique, albeit recycled, sequences. There's one for each alien creature Ben has the ability to change into (though Grey Matter's didn't actually get used until season two). Two more are added in season two, but one was lost after the events of "Ghostfreaked Out". Some are longer and more detailed than others, but all follow the same pattern of showing the change progressing outward from his wrist. Sometimes a simple green flash of light is substituted for the transformation, and red light is always used for Ben changing back. Seasons three and four added more new aliens, but no new sequences, oddly enough. Future-Ben supposedly had ten thousand alien forms but we didn't (obviously) didn't see all of them.
 * And one-shot villain Doctor Viktor gets his own Transformation Sequence, going from oversized scientist into Frankenstein-ish monster. It's only used once, though.
 * Ben 10 Alien Force also has the sequences, and he's gained an irritating tendency to say the name of each creature he's turned into when he's done. The changes are actually instantaneous, as he's shown an ability to simply switch between forms in seconds when needed. It also regularly shows him changing back. Both of the latter use the same "glowing green dots" effect.
 * One particularly humorous moment has Ben's parents (who have forbidden him from using the Omnitrix) managing to catch him in the act during one of his (around 10-second) sequences, in episode 20 of Alien Force.
 * The old Spider-Woman cartoon series features a transformation sequence for Jessica Drew to change into the titular heroine.
 * In Avatar: The Last Airbender the Avatar State has this happen with a pause that is clearly in real time, with most people just too scared to react when they see it. Azula commits a dire breach of anime etiquette.
 * It should be noted that Aang did try and protect himself, as he made himself a little cocoon out of crystals to cover himself. Wait a minute, that means this could of all been avoided if it weren't for Power Floats!
 * He learned from that event, though, and by the time the Avatar state kicks in again, it's instantaneous.
 * An Animated Adaptation of Shazam! featured Billy, Mary, and Freddy, and a drawn-out transformation sequence. Unlike most, they had sequences for transforming back to normal as well, and a variety of different stock sequences for various combinations of the main characters, transforming singly, in pairs, or all three at once. (Interestingly, the comic version is specifically stated to be instantaneous. In the 1970s it was furthermore stated that, between the speed of transformation and the blinding flash, most people don't know that Billy is Captain Marvel, even when he transforms right in front of them, though that hasn't carried over to post-crisis versions of the character)
 * In fact, Filmation in general. In addition to the ones mentioned above (He-Man, She-Ra, Shazam), there was also Web Woman, Super Strech and Microwoman, Fantastic Voyage, Filmations Ghostbusters (the 1986 cartoon), and Bravestarr (30-30 had transformation sequences when he went from bipedal to quadrupedal and back), just to name a few.
 * Hanna-Barbera's late 1970s Fred and Barney Meet The Thing featured The Thing (from the Fantastic Four) as a teenager (implied in one episode to be due to a "cure" gone wrong), but he could become the Thing by touching his rings together and announcing "Thing Ring, Do Your Thing". This also had a reverse transformation sequence, without a required phrase.
 * The series was mostly humorous in intention, and it even spoofed itself. At least one episode had the hero retreat to a nearby doorway to transform, only to be interrupted by an old woman exiting the door. She stopped long enough to give him a lecture.
 * Like Filmation, Hanna-Barbera was also good at filling time with these sequences. In addition to the Thing, there was also the Mighty Mightor (with a sequence very similar to He-Man, but predating it by twenty years), the Arabian Knights, the Impossibles, the Super Globetrotters, the Super Friends (in the Wonder Twins' segments), Wonder Wheels, Mighty Man and Yukk, the Drak Pack, and even the Swat Kats.
 * Hanna-Barbera also spoofed this trope with one version of Captain Caveman. On The Flintstones Comedy Show, he worked as a copy boy named Chester at a stone-age newspaper, disguising himself with a pair of glasses and his cape folded into a bowtie. Despite the minimal disguise, he still required a coat rack and an elaborate transformation sequence (which included heroic music, explosions, lightning bolts, rockets, fireworks, and stars, and was loud enough so that the entire city of Bedrock could hear it) to become Captain Caveman.
 * In Banana Man it's triggered whenever Eric eats a banana. Its most famous form is in the Opening Credits, in which Eric sprouts muscles and grows two feet.
 * Freakazoid! Had quite a variety of them in different episodes. One had him meeting a werewolf, who used the classic Universal sequence of a still of the human actor, a series of transitional paintings, and finally the actor in full makeup. Freakazoid then says "I can do that too!" and sits in the same chair, transitioning through a series of paintings of him doing weird faces, plus a few random cameos from other characters, before arriving at himself.
 * Subvert a bit, with Jerrica "Jem" Benton of Jem and The Holograms, which is only a "Showtime, Synergy" to summon Jem hologram and a "Show's Over, Synergy" to remove the Jem hologram -- the answer is usually a pink light and very quick.
 * The Powerpuff Girls: In the episode "Super Zeroes," the girls each try to change their look to be more like the super hero in their favorite comic books, complete with such elaborate transformations that, by the time they're done, the monster has left town.
 * In Spider-Man and His Amazing Friends, Spider-Man's amazing friends could do it, to his envy (since he has to actually put on his costume).
 * In the short lived and mostly forgotten 1999 animated series Spider-Man Unlimited (nothing to do with the comic with the same name) he finally got one via nanotech.
 * The 90's cartoon King Arthur and The Knights of Justice had a transformation sequence for each of the knights as they put on their battle armor. Sometimes it was further padded by transforming their horses.
 * Subverted somewhat in Danny Phantom, as the transformation sequence there is refreshingly simple and short, while still being rather stylish with a chance to play around with it and not use Stock Footage. Whenever the titular character wants to transform into the titular alter-ego he simply focuses for a few seconds, a ring of blue white light appears, bisects and travels over him, leaving one superhero in place. Easy, done.
 * Big Bad and Evil Counterpart Vlad has an almost identical Transformation Sequence, except that his ring of energy is black.
 * Monster Buster Club: "MBC, poooooooower up!!"
 * Mummies Alive had this.
 * Most of the time after the first few episodes this happened in Static Shock, even though his costume was just regular clothes altered by the hero to obscure his identity.
 * The Nickelodeon TV movie Groove Squad, which was about three cheerleaders who could transform into, you guessed it, superpowered cheerleaders by drinking a magical red juice. After they drank said juice, the girls went through a rather overdone transfomation sequence to change into their superheroine forms.
 * In ThunderCats and reboot ThunderCats (2011)
 * The Hero Lion-O's weapon, the Sword of Omens, has a stock transformation sequence via By the Power of Greyskull where the blade lengthens from dagger to longsword while sparking impressively and shooting Sword Beams, recreated shot-for-shot in the reboot.
 * Mumm-Ra, lead villain has a stock transformation sequence with a By the Power of Greyskull into a more intimidating One-Winged Angel. Incidentally, he also becomes a lot less clothed in the transformation.
 * Mon-Star, main villain of Silverhawks, had a very similar transformation sequence to Mumm-Ra. One interesting note is that he grows metal spikes from various parts of his body, which is animated in a way that looks fairly painful, but no mention of pain is made.
 * This was one of the reasons that the Avengers cartoon was so poorly received by fans of the comic. Ant-Man, Wasp, Falcon, and Hawkeye all got elaborate Transformation Sequences that involved being covered by armor that was, for the purposes of their abilities, completely unnecessary. It didn't help that it added to the fact that none of these characters were wearing anything remotely like their comic book costumes.
 * Parodied in the South Park episode "Good Times With Weapons," in which the kids buy some real ninja-weapons that -- in their imaginations -- transform them into crime-fighting ninjas through a lightning-transformation sequence... and who end up almost putting Butters's eye out with a ninja-star, as a parody of the potential harm caused by violent cartoons.
 * Done again in "Coon vs. Coon & Friends", when Bradley plays a superhero called Mint-Berry Crunch who has superpowers he could call upon by turning in place and saying the magic word, "Shablagoo!"
 * There's also "Korn's Groovy Pirate Ghost Mystery", in which the band is faced with a lynch mob of townspeople and titlar pirate ghosts. Although they're generally a parody of archtypical protagonists in Scooby-Doo-type mystery shows in this episode, Korn launches into an obtuse transformation sequence that turns them into... . Even the pirate ghosts are stunned.

Cartman: That didn't help at all.

Head: We know. It's just cool to do."


 * Played almost completely straight in the Tiny Toon Adventures short "The Amazing Three", when Babs breaks out the "Acme Loo Wonder Makeup Kit" -- complete with a outer space-themed Love Bubbles background and Orbital Shot (possibly a Shout Out to Sailor Moon, but it also predates the anime by a year, so this could be wrong).
 * Lampshaded and spoofed in Megas XLR: when a group of Magical Girls confront Jamie, they transforms. Jamie just stands there waiting patiently and bored, until they finally finish after more than a minute.
 * Even better, the Sailor Moon Expy had a longer sequence than the others, so while the other girls were already done and posing, she kept spinning and spinning and spinning...
 * in The Little Mermaid, Ariel's transformation when turning from mermaid to human. + 1 as she's mostly naked afterward.
 * There's another transformation sequence in the same movie, though without the nudity. All the in-between stages of Ursula's transformation into Vanessa are extremely creepy, and her Evil Laugh doesn't help.
 * Snow White and The Seven Dwarfs brings us the awesome transformation of the Wicked Queen to her witch form.
 * Super Chicken and his Super Sauce.
 * She-Hulk's transformation scene in the 1990s Incredible Hulk episode "Doomed" is still venerated for graphic depictions of female muscle growth and Breast Expansion while Jennifer Walters apparently has an orgasm.
 * Hal Jordan also got one of these in Green Lantern First Flight.
 * Brother Bear has the scene near the beginning of the film where Kenai is actually transformed into a bear as punishment for betraying his late older brother.
 * Disney's Atlantis the Lost Empire has the scene where Cree Summer's character, Kidagakash, is transfomed into a beautiful goddess-like sprite after merging with the Atlantean Crystal.
 * In the Voltron Force episode "Flash Form a Go", the force meets an enemy that refuses to follow transformation chivalry, ramming the lions apart whenever they try to form Voltron, an act that takes precisely 36 seconds, according to Daniel.
 * Super Duper Sumos: The sumos goes through a transformation sequence to become "Sumo-Sized."
 * In Teen Titans, Cyborg had a rather epic one in The End: Part 1. He connects himself to the main Titans Tower power system, unloads some very big guns against a glowing white background with crackling electricity and shoots Slade and his minions with the mother of all sonic blasts. ...Doesn't stop Slade, but it was worth a shot. Unfortunately, this is never used again.
 * Kaeloo, Once an Episode. Somewhat odd as she has been shown on many occasions to be able to transform into her Bad Kaeloo form near-instantly.
