Transformation Comic

A Transformation Comic is centered around a magical or Applied Phlebotinum transformation of some sort. One variety transforms a main character for the long term, and follows the consequences of this incident; another involves repeated transformation of several characters, and a third variety mixes these. Since transformation as a primary theme tends to appeal to a niche market, most examples are Web Comics, which can be published easily and cheaply, and usually with few or no editorial restrictions on content.

While a Transformation Comic might have some Author Appeal or be slanted towards specific Fan Service and/or Fetish Fuel, transformation can also be used to explore such themes as gender roles, racism, feelings of isolation/not belonging, and the maturation process.

For purposes of this page, examples will exclude comics where transformations occur, but are not central to the storyline or themes.

Types of transformation seen in a Transformation Comic include but are not limited to:
 * Gender Bender - Male to female is most common (First Law of Gender Bending at work), but female to male or either to hermaphrodite are not unknown. This does not include characters who are realistic transsexuals or transvestites, though they may also appear in the strip.
 * Animal Transformation - Human to either anthropomorphic (furry or kemonomimi) or "normal" animal, or vice versa.
 * Species Transformation - Human to alien or magical being, and vice versa.
 * Age Change - Both Overnight Age-Up and Fountain of Youth.
 * Cultural/Ethnicity Change - Black Like Me, White Like Me and so forth. Relatively rare, possibly because Race Tropes are likely to trigger some readers' Berserk Button, and thus it can be easier to deal with them through Fantastic Racism if the author is interested in approaching those subjects.
 * Mental Change - The character becomes Not Himself.
 * Mind Swap - Can be any of these, but applied to two characters at once, sticking them with each other's bodies in a Freaky Friday Flip plot.

If one of the main characters has Functional Magic or Mad Science skills, even more exotic transformations may show up from time to time.

Note that the vast majority of these comics focus on involuntary transformations—either a Curse on a specific individual, or a few characters who transform others as a habit (or hobby).

Anime & Manga

 * There have literally been dozens (if not hundreds) of manga titles (mostly hentai) using gender swaps as the central dramatic (and pornographic) device. So many of them have been based on a Freaky Friday Flip caused by two characters either banging heads or falling down the stairs together that these two plot devices have become recognizable (and lampshaded) manga tropes in their own right. Most of these titles were never translated or exported to the west, but a more or less representative selection can be found here.
 * Ranma ½ is probably the most successful example by far.
 * Futaba Kun Change has the main character change gender whenever aroused.
 * Kämpfer features Gender Bender, Mental Change, and inflated body proportions.
 * Ichinensei ni Nacchattara: Ordinary (male) High School Student gets transformed into Ordinary (female) first grade student. Hilarity Ensues
 * Boku No Shotaiken: Mad Scientist transplants the brain of a suicidal High School student into the body of his recently deceased young wife. Probably the first mainstream Gender Bender manga ever published.
 * Nanaka 6/17: The latter is her physical age, the former the one her mind changes to.
 * Fruits Basket is the current reigning Animorphism champion.
 * Girl in My Dream is a Korean Manwa which starts as a Girl of My Dreams scenario but quickly turns into a Grand Theft Me
 * Puchi D Kemono (NSFW) starts each chapter with an animal that turns into a kemonomimi a few pages later.
 * Return: Bright but nerdy schoolboy Kai wakes up in the body of Troubled but Cute schoolgirl Mariko after dying in a motorcycle accident only to find the best friend who caused the accident seemingly indifferent. Determined on revenge, Kai uses his "diguise" as Mariko to get closer to him, only to find that Tatsuki is not nearly callous as he seems. More complications ensue when Mariko's spirit returns as well. It turns out she was not dead, just comatose, and she's not quite ready to surrender her life and body to a complete stranger.
 * Ame Nochi Hare: Five first-year high school students got caught in a violent thunderstorm and sought shelter in their school building when a lightning strike mysteriously transformed into girls. Complications ensue when they discover their transformations, while temporary, will trigger whenever it rains.
 * Maomarimo: gentle middle school boy Mao gets turned into a girl when he takes his twin sister Akoya's place as their village festival's "sacrificial virgin". She seems more upset by this than he does.
 * CUTExGUY: Another Gender Bender comedy manga but a Shojo one with a female-to-male lead
 * Greater East Asia Co-prosperity Sphere is a Body Horror Fetish manga played for heavy Squick. To summarize, Imperial Japan uses the power of a magical meteor to turn young woman into gigantic, nighmarish organic war machines. Look it up online if you dare with the caveat that once seen it cannot be unseen, no matter how much you should wish it.
 * Animal X: Animorphic dinosaurs hide amongst us. They want our ukes.
 * Your and My Secret: Aggressive girl exchanges bodies with passive boy. everyone seems to think it's an improvement.

Comics

 * The original Captain Marvel is a small boy who has a Plot-Relevant Age-Up when in his powered form. Every so often, the fact that he's essentially a child in a grown man's body becomes a plot or characterization point.
 * Similar to Captain Marvel above, Amethyst, Princess of Gemworld ages up to an adult woman from a 12-year-old girl when she visits her home dimension, due to time moving at different rates in the two universes.
 * Incredible Hulk: Mild-mannered doctor transforms into monstrous creature whenever he gets angry.
 * Billy the Cat: A boy who is cruel to animals is punished by being (depending on the medium) transformed or put into the body of a cat. In the animated series this is more of a Freaky Friday Flip.
 * Safe Havens: Samantha Argus is a grad student at Havens University who has unlocked the genetic code that allows her to transform anyone or anything, including herself.
 * Jimmy Olsen during the Silver Age couldn't go more than an issue or two without undergoing some bizarre transformation or mutation. Just about every kind on the list you can think of aside from Gender Bender (unnecessary because of his status as a Wholesome Crossdresser?)
 * Superboy actually was on the receiving end of a Silver Age Gender Bender once, and (also as Superman), went through quite a few transformations of his own during the Silver Age. Frequently caused by exposure to Red Kryptonite, here's a very partial list of transformations: split into two people, given the head of an ant, turned into a non-superpowered giant, turned into an infant with an adult mind, and many, many more.

Web Comics

 * Misfile. Ash is a Gender Bender and Emily has been hit with a Fountain of Youth. The former is used to deconstruct most gender bender tropes and the latter is a very subtle use of the trope as she's only "lost" two years. They just happen to have been two very important years from her perspective.
 * Abstract Gender. Brian and Ryan are both on a Gender Bender; Brian (who likes it) can go back to his original form, while Ryan (who doesn't) can't, a cause of considerable irritation on the latter's part.
 * El Goonish Shive: From Gender Benders to shapeshifting, magic to mad science, EGS showcases every form of transformation known to Dan.. Every major character has been transformed at least once. In fact, one could even argue that a character isn't truly a main character until they've been transformed at least once.
 * Sparkling Generation Valkyrie Yuuki. Yuuki, of course, is a Gender Bender for the long haul. Hermod and Loki are both currently in Animal Transformation, with Loki additionally being a plushie.
 * Zebra Girl. The title character is permanently stuck with the body of a demon. Probably the least Fan Service-y example of the genre—the fact that Sandra's every bodily secretion is now incredibly acidic might have something to do with that.
 * They did have a quick scene where fanservice was alluded to, but offscreened, early on. Later, some more explicit fanart of the incident was drawn, but nothing too revealing.
 * Urgent Transformation Crisis is surprisingly serious about its subject matter. The transformations are usually one-way, less fan-servicey than normal, and the implications are taken far more seriously than in other strips of this nature. Hard-to-reverse transformation with life-changing effects would be a crisis, after all.
 * The Wotch. The title character and most other magic users in the strip tend to rely heavily on transformation spells. Interestingly, due to the nature of her powers, Anne is unable to be a Gender Bender herself. But she and her friends have undergone many transformations, some voluntarily. A number of supporting characters are permanently genderbent, with a special mention going to Mingmei, who has a trifecta of Gender Bender, Fountain of Youth and Asian Like Me. She used to have Not Himself as well, but her personality seems to have reintegrated. There are also a Werewolf, a werecat, a couple who swap bodies every so often as a Running Gag (and, amusingly enough, she enjoys it and wants to keep it up), and a formerly-human centaur, just in case the gender games weren't enough.
 * Cheer. A spin-off of The Wotch, featuring a quartet of Gender Bender cheerleaders, as well as an additional White Like Me Gender Bender (Peter Hall) who (unlike three of the other four) knows exactly what's happened to her. All of the Wotch regulars make appearances as well. One of the cheerleaders
 * Troop 37 focuses on a ten-year-old boy turned into a sixteen-year-old girl for reasons that, as a rule, are not to be explained. Written by first caller.
 * MSF High features frequent transformations (in which the victim always, always winds up female), mostly at the hands of the nurse, or occasionally Lovable Rogue Rainer. The victims have the option of reversing them at the end of the day, but seldom do, for various reasons. The artist of its predecessor, High School Changed Me, quit over, ahem, Creative Differences and later put a Take That in his own strip when a familiar-looking Spear Carrier wishes to be turned into a woman.
 * Note that Rainer has reversed transformations for multiple reasons, and more recently, a girl has been turned into a guy. Also has an active forum roleplay.
 * Discordia is a low-key strip about a man who's been transformed into a woman. A character also has the power to transform anyone but the aforementioned, but she's an innocent, albeit half-god, little girl, and mostly uses it on command. A consequence of her innocence, however, is that she can't produce a male form - even if the target started that way.
 * Panthera: A webcomic about a group of high school teens who transform into Big Cats in order to help their chemistry teacher wage war on some kind of "Evil Organization".
 * Sailor Sun is about an actor permanently stuck as an actress, who always manages to just miss Those Two Guys switching each others' genders as a prank, and the "actress" playing The Wotch using Gender Bender powers. Not to mention that authorities on the subject have claimed it too risky for some reason.
 * I Dream of a Jeanie Bottle by the same author is about a guy permanently stuck as an I Dream of Jeannie-style genie with her best friend being her master.
 * Accidental Centaurs is Exactly What It Says on the Tin - two scientists become centaurs after an exploding teleporter sends them to a world where centaurs are real and humans are mythical. Other transformations ensue, usually at the behest of a tame genie, and a crossover with The Wotch ended with one of the main characters getting some of her powers...and the same basic move.
 * New World has a large number of magical transformations, most of which involve both genderbending and either age regression or furry transformation (or in the case of Mina, all three at once). It has since been rebooted as a straight Gender Bender comic, Spiderwebs...and then re-re-booted as New World again.
 * Crossworlds began as a side story to Accidental Centaurs and is tied to The Wotch through it. While its plot isn't entirely tied into transformation, the artist uses it often enough that it seems to qualify. (That, and the artist draws transformation art on his other website seems to help.)
 * Exiern is the story of a barbarian adventurer turned into a woman by a sorcerer's spell gone awry. Hilarity and Fan Service ensue in equal measure, as well as other characters transforming in various ways. The sub-comic Dark Reflections takes the same plot and spins it around as a What If the hero didn't save the princess in time. In this version the gender-changed hero/heroine ends up mind-controlled by the Big Bad and becomes his bimbo Dragon.
 * The fancomic Char Cole details a Pokémon journey from the perspective of a human-turned-Charmander.
 * ''Synthea is a trope-filled comic about a amnesiac woman ending up in a Stasis pod right before death being woken up in the distant future by a good Mad Scientist using experimental ancient biotech that gave her a body with the consistency of lime jello—a so called Slime-Girl. Synthea gains some powers from the shift—she can change shape at will, stretching, punching, creating mallets, etc, but her control over her body is very limited, as she oozes and drips all over the place. She even has to sleep in a barrel as when unconscious she reverts to a big puddle. She's also apparently physically immortal—she's been cut up, blown up, and vacuumed up by a sapient humanoid vacuum with little more than a headache.
 * The two sets of webcomics based on Erika's New Perfume are minor forms of this, as they play on the transformations of Marie and Sarah but do not so far include any more from there.
 * The Dragon Doctors - Four magical doctors, a shaman/therapist, a surgeon, a magical scientist, and a wizard all get their respective genders reversed in the first chapter while trying to cure a cursed valley that causes everything within it to be female. They wind up stuck that way, and deal with that as they continue to diagnose and cure unusual diseases, curses and other problems—their methods often involving additional transformations—in a Schizo-Tech fantasy setting.
 * Demon Eater has demons that change form every time they eat another demon. It's a dog eat dog world for reals. Saturno the main character has so far been in 30 different forms and counting.
 * The Key to Her Heart follows a part-time Gender Bender's relationship with a closeted lesbian, and occasionally features further one-off transformations, especially in dreams. Since it's marketed as an adult comic and has a graphic sex scene at least per chapter, any Fetish Fuel is purely intentional.
 * Gender Swapped is similar to Misfile and Abstract Gender in that the main characters have to deal with a form of permanent Gender Bender. There's also some age regression involved.
 * She !s me (Oh no! I'm a girl!) The story of a guy who one day wakes up as a gal. Don't think of this as a funny bodyswitch comedy, but as a serious evaluation about the question "What would you really do if ...?"
 * Paradigm Shift is a Buddy Cop Comic centered around werecreatures being real.
 * The Good Witch begins with the former holder of the title passing it on to a transgirl named Angel, fulfilling her wish to be a genetic girl (and retconning everyone's memory that this had always been the case.) As the Good Witch, Angel has amazing transformation powers...that she's severely abusing.
 * Spinnerette: A Freak Lab Accident leaves a mild-mannered grad student Multi-Armed and Dangerous; any resemblence to another costumed webslinger is purely intentional - and hilarious.
 * Jet Dream concerns the adventures of a Blackhawk style Multinational Team of aviators, the Thunderbird Squadron, after being transformed from T-Birds to T-Girls.
 * Dream Tales comics feature growing and shrinking as well as age regression themes.
 * The Beast Legion is completely built on the concept of transformation & magic. Most of the characters have their own pieces of armore called 'Beast Transfers' that allow them to turn into Mystical beasts with Awesome powers.
 * Somewhere Different, about a boy who is run over by some scientists, who bring him to their lab to heal him but also take the opportunity to experiment on him
 * T Random Watch has Grant and Amy both experience transformations, as well as one of the government agents.
 * Type Trainer, a Pokémon fancomic about Ash getting turned into a Pikachu.
 * Jill Trent Science Sleuth, the Remix Comic version, features a male hero transformed by the wonder element Femavium into a woman with the proportional brain cells of 58 girls.
 * 1-600 is a comic about a boy who finds a mysterious number that allows you to turn into an animal once called. Read it here http://www.1-600.net/
 * Witchprickers: Ilemauzer, a timid familiar bat, asks the cheery Old Scratch to turn her into a human, only to turn into a Humanoid Animal instead.
 * High School Changed Me: the predecessor to MSF High. While not the premise of the web comic, transformations into other species or genderbending were quite common.
 * Skin Deep reverses the usual take on this subject since the main characters are all mythological creatures transformed into humans. In this case human is the transformation.
 * The website TGComics.com (mostly NSFW) is devoted to gender transformation comics, many of which are less pornographic than you'd think. While TGComics.com focuses on original art (including a large number of works created with Poser and similar programs), sister site TGCaps.com is devoted to TG Remix Comics.
 * Wereworld: revolves around Steve, a cyborg who comes to the eponymous planet looking to make his body stop rejecting the implants. The planet, Sidra, is inhabited by several species of human-animal transforming hybrids.
 * Rubys World has the main character turned into a nine foot tall giantess, though this soon becomes the least of her problems.
 * Ruby Nation continues Ruby's story, as well as introducing Elise, a girl who has apparently sprouted large metal wings.
 * Shifters is a Web Comic heavily involved with Werecreatures.
