Adaptational Curves
Luke only gets like this when he sucks his gut in.

Sex sells, and thus when adapting a work from the page to the screen, executives often feel that, in the interest of attracting more moviegoers, certain liberties can be taken with casting. And thus, a character described as scrawny or flat-chested in a novel might magically become muscular or buxom in the film based on that novel.

May overlap with Adaptational Attractiveness, though there's no guarantee that the bustier actress or more muscular guy is necessarily more attractive. May also be a result of Dawson Casting or an Age Lift. Male examples of this trope often go hand-in-hand with Adaptational Badass. The opposite of Big Bra to Fill. When fan artists do this, is Self-Fanservice. If this happens gradually within the same series, see Fanservice Pack.

     Anime & Manga 
  • Black Clover: In the manga, it's implied that male mages aren't particularly fit, with the exception of Yami, but in the anime adaptation, all of them are as muscular than Asta, if not more, which undercuts the point that Asta has spent his life training his muscles and is more physically strong than most mages.
  • General Esdeath from Akame ga Kill! was around Sheele's breast size in the manga. The anime increased her to Leone's size.
  • Attack on Titan: Mikasa Ackerman is flat-chested in the manga, as illustrations of her in a sports-bra and a magical girl costume demonstrate. In the anime, on the other hand, she is given a noticeable bust, as displayed in the second opening and a bonus episode where she does exercizes.
  • Ruiko Saten from A Certain Scientific Railgun was flat-chested in the manga, but not so much in the anime. Compare this to this.
  • Daily Life with Monster Girl:
    • Doppel is flat-chested in the manga and anime. In the mobile game, however, she is much more buxom. Uniquely, this is justified due to her abilities as a shapeshifter — though she hasn't demonstrated this particular aspect of her abilities in the source material.
    • Papi has a noticeably larger chest in the anime, presumably to make her look a bit older.
  • Inverted with Final Fantasy VII: Advent Children. While in the original game, Tifa had exaggerated breasts, the follow up movie reduced her cup size because they would have looked jarring on the more realistic character models. Of course, even with reduced breasts, Tifa is still enormously busty.
  • Gate: In the manga, Hamilton is flat chested and teased for looking like a boy. In the anime, she has small breasts.
  • GONZO is rather infamous for this in their adaptations, with notable examples being Strike Witches, Saki, and Linebarrels of Iron.
  • One Piece: The Dressrosa Arc Up to Eleven this, especially with Rebecca. The anime in particular has conspicuously enlarged her breasts and frequently delves into filler by showing her fights.
    • The anime in general has been bad about this since at least Water 7. Women's breasts are noticeably larger in the anime than in the manga. Mostly starting with Nami in her Enies Lobby outfit.
  • In the Yu-Gi-Oh! GX anime, Asuka has large but not unreasonable breasts and long legs. The manga ramps both up a few inches for a more exaggeratedly curvaceous figure.
  • May in Pokémon Ruby and Sapphire has an average sized chest for someone around middle school age but her Pokémon anime counterpart is infamous for changing sizes often, though it's usually at minimum a cup larger than she should - especially for a 10 year-old. When she reappeared in Diamond and Pearl they sized her down to be more similar to the game version.
  • Tsugumomo: The anime version of Kiriha is far more buxom and shapely than her manga counterpart even after the latter's Plot-Relevant Age-Up.
  • In Soul Hunter, Ko Hiko's sister Koshi in the manga was quite tomboyish and petite. In the anime adaptation, not only she plays a different role, but her breasts are much bigger and her clothing shows them off better. The same goes for Dakki in her anime-only One-Winged Angel.
  • In the second anime adaptation of Ushio and Tora, Kagari the kamaitachi is more voluptuous in her human form, compared to her slimmer manga self.
  • Inverted for the High School D×D anime, where Ravel Phenex is depicted with smaller-than-expected breasts, apparently to make her look more like the "little sister" niche she was actively filling (long story). Ishibumi has gone on record stating he considers this artist error, and her appearances in later seasons give her a chest more in line with novel illustrations.
  • In the Sun and Moon chapter of Pokémon Adventures, Professor Kukui is much beefier than his game and anime counterparts. That's what happens when you use Dwayne Johnson as a drawing reference...

     Comic Book 
  • Salem is larger in Chilling Adventures of Sabrina than he is in Sabrina the Teenage Witch.
  • Most comic-book adaptations of the John Carter of Mars books have seen fit to portray Green Martian females with breasts. In the original books, it's not clear that they have breasts, or that they nurse their young.
  • Jem's IDW comics changed the body types of several characters. Aja and Stormer gained weight, Shana is curvier, Roxy is more muscular, and Rapture has larger hips.
  • In the comic book adaptation of Guards! Guards!, the single panel flashback to Mistress Garlick the witch declaring that Carrot's sword is "the most unmagical sword I've ever seen", does not fit the "peas on an ironing board" description in Wyrd Sisters (although it's clearly an interpretation of Magrat otherwise).
  • The comic adaptation of Lost in Space has more curvy versions of both Penny and Judy.
  • Power Rangers comics tend to portray the women as more curvaceous and gives all the male heroes a Heroic Build, making them much more muscular than the relatively thin stuntmen and women that play them in the live action show.
  • Sally Acorn and Bunnie Rabbot of Sonic SatAM had somewhat feminine proportions, but were still clearly Funny Animals. Many artists of the Archie Comics' Sonic the Hedgehog comic book have drawn the two (and many other recurring Mobians) as full on Petting Zoo People, with Bunnie's cyborg limbs even canonically redesigned just to fit this. This was downplayed as the comics tried to emulate the games' design style more. Going even deeper to the source games has Ricky, who Sally is based off. Ricky is a non-anthropomorphic (male) squirrel.

     Fan Works 
  • The Black Emperor: Owing to some intensive training with Sayoko, Lelouch has a more muscular build than his canon counterpart does.
  • In Child of the Storm, the formerly short and skinny Harry hits a growth spurt thanks to his grandmother correcting malnutrition stunted growth and setting a proper diet and being a teenager whose dad happens to be Thor. Additionally, hand to hand combat training leads to him putting on additional muscle, something noticed and appreciated by an increasing number of straight/bi female students, and gay/bi male friends. The result is that part way through 3rd year, he can pass for 15/16, and by the time he's around 14 and a half, he can pass for 17/18.
  • Code Geass: The Prepared Rebellion:
    • Lelouch is a good deal more muscular than in canon, thanks to being more willing to exercise.
    • Sayoko is quite bustier than she was in canon, having D-cup breasts.
  • Evangelion 303: Due to being twenty-one, stopping exercise due to a plane crash that rendered her comatose for several months and a change in diet, Asuka is more stacked than she was in the original show.
  • Pokémon Reset Bloodlines:
    • Misty has a more impressive figure than she did in the anime. This is justified, because she's five years older than she was in the original timeline and closer in age to her sisters in the original show, who were quite curvy.
    • This applies to other characters who have aged up, including Ash and May. Iris however is stated to not be particularly curvy.
  • Coreline: Multiple Alternate Self versions of characters that appear are mentioned to have more muscles than their canon version. Justified because many of those Alternates (that have appeared so far) are superhero versions of a character and several of these are shown (or at least heavily implied) to have taken Boxing Lessons for Superman (or at least gotten some exercise as a general part of their taking as level in badass).
  • While fairly curvy in canon, Nabiki Tendo in Anything Goes Game Changer is not only more obviously fit, but has a bust comparable to Akitsu.

     Film — Animated  
  • Pohatu from BIONICLE had scrawny arms and a tiny upper-body (what with his gear-function being in his hip) as a toy, but, overlapping with Adaptational Attractiveness, has a normal body and more proportional arms in the Direct-to-DVD film. Sidorak from the third movie is also much more buff than his scraggy toy.

     Film — Live Action  
  • Baywatch has this spades - compare David Hasselhoff's Mitch Buchannon to Dwayne Johnson's, Alexandra Paul's Stephanie Holden to Ilfenesh Hadera's, Alexandra Daddario's Summer Quinn to Nicole Eggert's.
  • In Daredevil, the Kingpin, who in the comic looks like a fatty but Word of God states is all muscle, is played by Michael Clarke Duncan.
  • In the original novel Emmanuelle: The Joys of a Woman, the eponymous character becomes fascinated by Bee because the latter is almost breastless. In the film Emmanuelle, Bee was played by Marika Green, who was definitely not flat-chested.
  • Some characters in the Harry Potter movies were more muscular than their book counterparts. Ron, for instance, was described as tall and skinny in the books, while Rupert Grint was rather buff in the later movies. Similarly, Neville was short and chubby in the first few movies, fitting his appearance in the books, but puberty was really kind to Matthew Lewis, who became tall and muscular in the later films.
  • When Jennifer Lawrence was chosen to play the lead in the film adaptation of the The Hunger Games, enraged fans almost immediately complained that she was too voluptuous to play Katniss Everdeen, for whom being perpetually underfed was a defining trait. Jennifer Lawrence's response was that she didn't want to perpetuate women's Weight Woe.
  • The American-made Mighty Morphin' Power Rangers: The Movie featured the characters wearing redesigned costumes that were plated like Power Armor rather than the usual spandex, and made the characters look more muscular than they do on the regular TV show.
  • In On Her Majesty's Secret Service Blofeld is portrayed by Telly Savalas, a fairly buff dude. In the books, Blofeld is described as someone whose "muscle has all turned to fat."
  • In the book of The Running Man, protagonist Ben Richards is described as "scrawny" and "pre-tubercular". In the film, he's played by Arnold Schwarzenegger.
  • In Spider-Man, the spider bite that gave Peter Parker his powers also makes him slightly buffer. In the original comics, The Amazing Spider-Man films, and many other incarnations, the spider bite had no such effect.
  • Star Wars:
    • Some versions of the poster for the original Star Wars movie exaggerated Princess Leia's proportions, to a Fanservice -ish degree.
    • The late-90's toy line based on the series had a tendency to make the male characters far more muscular than they were in the films. It got to the point that Mark Hamill saw a figurine and remarked, 'Dear God, they put me on steroids!'
  • In the X-Men comics, Wolverine is a Pint-Sized Powerhouse at 5'2". The films cast the 6'2" and very ripped Hugh Jackman to play him.

     Live-Action TV  
  • The 2000 Syfy adaptation of Dune cast the noticeably voluptuous Barbora Kodetova as Paul's love-interest Chani, who was supposed to be slender and devoid of body fat. It's probably just a coincidence that the uncensored version of the mini-series featured Kodetova in a topless scene...
  • Generally inverted in The Flash (2014).
    • Barry Allen is usually drawn as a highly muscular man in the comics, but is given a Geek Physique.
    • Francisco "Cisco" Ramone trades his bodybuilder-like figure for a shorter, slightly stouter frame.
    • Savitar is drawn as a Walking Shirtless Scene with the muscles to match, but the show gives him the same scrawny build as Barry, since Savitar is just an alias used by Barry's evil future self.
  • Game of Thrones:
    • Missandei is quite a few years older than her counterpart in the A Song of Ice and Fire series, who's only about eleven, and thus more shapely.
    • In the books, Brienne has a stocky, masculine physique and no bosom at all. Osha is lithe and barely looks like a woman. Both have more feminine figures in the show.
  • Power Rangers: What the movie and comics do for the show, the show itself does compared to its Japanese Super Sentai material. In Sentai, the boys are Bishounen and the girls are often reverse-Dawson Casting cases; everyone's younger and slenderer than you'd expect. In PR, you'll find considerably more muscles on the boys, and more curves (and muscles, though the full-on Amazon-looking cases are rare) on the girls. One of the best cases is is Gekiranger/Jungle Fury. Rio looks like he belongs in a boy band. He looks masterful in a smooth, aristocratic sort of way. Dai Shi looks like he could dismantle you without summoning his battle armor, and fitting with the lion theme is generally more feral-looking.
  • Jane Rizzoli is described as "plain" in the source books, but is played on television by Angie Harmon, who is...not.
  • Saturday Night Live once poked fun at Harry Potter, in which guest host Lindsay Lohan was playing Hermione, returning to Hogwarts after summer vacation, having developed a pair of gigantic breasts, and unintentionally drawing so much attention to them that neither Harry nor Ron can keep his eyes off them. This also was Lohan poking fun at herself, as at the time, she was developing and blossoming, and her breasts grew naturally large, and thus many people were speculating that they were fake.
    • Coincidentally or not, this exact scenario is also a well-worn plot device in Harry Potter fanfiction.
  • The TV version of The Walking Dead gave the already beautiful Maggie Greene height and bust-size upgrades by casting Lauren Cohan.
  • In the Archie comics Ethel Muggs is an awkward skinny brunette. As played by Shannon Purser on Riverdale she's got reddish hair and a much curvier figure.

     Video Games 
  • An in-universe version occurs in Dragon Age II, where Varrick's initial story makes Bethany much bustier than she is in the "true" story.
  • Sonic Boom (and its accompanying animated series) feature a more muscular version of Knuckles than has appeared in previous works.
  • Promotional art from BlazBlue: Cross Tag Battle has the cast from RWBY depicted with more notable busts than they had in their original series. Even Yang.



     Western Animation  
  • Blackarachnia's toy from in the Beast Wars line was a Palette Swap of the stocky and fat Tarantulas. The show gave her a more realistic black widow spider mode, and her robot form was modeled after a thin but well-endowed exotic dancer.
  • Sally from Sonic SatAM is loosely based on Ricky, who is non-anthro and male (though in the 90s he was female in English countries). Sally has a more feminine figure than most Sonic characters.
