When a work is being adapted, liberties with the original will have to be made. Due to time or length constraints, some things may have to be taken out. Sometimes it involves taking out a character who was very important in the original story.

Could happen because of AdaptationDistillation, in a CompressedAdaptation or a PragmaticAdaptation. These characters would usually fall victim to the existence of a CompositeCharacter, with which there is often plenty of overlap. Another possibility is that maybe some aspects of the work [[RefittedForSequel may be saved for]] [[SequelHook potential sequels]].

Related to ChuckCunninghamSyndrome, where a character vanishes without explanation from the original work. Compare DemotedToExtra, where the character does appear but in a much less important role. Contrast CanonForeigner. If a character is cut from an adaptation of an ongoing work but then turns out to be [[ChekhovsGunman extremely important later on]], this could result in an AdaptationInducedPlotHole.

Examples are listed in the original format of the media being adapted from as opposed to the medium they are being adapted to.



[[folder: Adapted from {{Anime}} and {{Manga}}]]
* ''[[Manga/MidoriNoHibi Midori Days]]'': The anime version is only 13 episodes long, whereas the manga is 85 chapters in all. Because of the difference in length, characters like [[BadassAdorable Nao]] and her father, [[MadScientist Shirou]], were left out of the anime, along with [[ForeignExchangeStudent Lucy]].
* Krillin isn't in the live action adaptation ''Film/DragonballEvolution'', even though Piccolo (who appeared much later than Krillin did) is.
* Minamoto Shizuna-sensei is absent from Creator/StudioShaft's TV anime adaptation of ''Manga/MahouSenseiNegima'', and Takahata-sensei pretty much takes over her parts in addition to his own.
* The direct manga adaptation of ''Anime/CodeGeass'' cuts out the [[HumongousMecha Knightmare Frames]], which reduces the scale of the story overall by taking out a hefty chunk of the military aspect. Also removed are characters like Cornelia, who tied heavily into the military part of the anime.
** ''Suzaku of the Counterattack'' cuts out most of the Ashford Academy characters, and [[CompositeCharacter rolls Shirley, Cecile, and Euphemia up into a new character]].
* Nozomi is absent from the anime adaptation of ''Manga/ElfenLied'', despite being the reason the story is called Elfen Lied in the first place (it's a song she sings.)
* Though he still appears in a supporting role, Toji is replaced by Asuka as the pilot of Eva Unit 03 in the ''Anime/RebuildOfEvangelion'' movies. Gaghiel is also replaced by an unnamed, clock-like Angel.
** Due to the condensed nature of the movies, a lot of the Angels were either omitted or made into [[CompositeCharacter Composite Characters]].
* Aoshi, the Oniwabanshuu, and the Hiruma brothers are all omitted from the live-action ''Manga/RurouniKenshin'' film due to [[PragmaticAdaptation pacing issues]]. Aoshi's role as Kanryu's bodyguard and Gohei Hiruma's role as the impostor Battousai [[CompositeCharacter are both given to Jin-e]].
** The second film will feature Aoshi and the Oniwabanshuu (at least Misao and Okina,) alongside the Juppongatana.
* Manga/SailorMoon:
** The following Sailor Guardians do not exist in TheNineties [[Anime/SailorMoon anime]] at all: [[spoiler:Sailor Ceres, Sailor Pallas, Sailor Juno, Sailor Vesta, and Sailor Cosmos]], albeit the first four still appear as characters (specially as villains who undergo a HeelFaceTurn) but never become Sailor Senshi.
** Several villains from the Manga's Shadow Galactica are also nonexistent in the anime's final season.
** Due to practical reasons, [[TeamPet Luna, Artemis, and Diana]] are omitted from most of the ''Theatre/SeraMyu'' musicals.
** Umino does not appear in ''Series/PrettyGuardianSailorMoon''.
* Speedwagon, Jack the Ripper, Dire and Straizo were all removed from the movie adaptation of ''Manga/JojosBizarreAdventure''. The fan response was so negative that the movie has never been released on DVD, ''even in UsefulNotes/{{Japan}}''.
* The 2003 ''Anime/FullmetalAlchemist'' anime cut out a lot of the cast who were introduced partway into the series (the Xingese characters, the Briggs soldiers, etc.) since the anime OvertookTheManga.
** The Video Game "Curse of the Crimson Elixir," which loosely adapted the first few chapters of the manga before beginning its original storyline, almost completely removed Shou Tucker from the game, instead treating him as a PosthumousCharacter as Ed and Al investigate his house just minutes after Scar has killed him.
* Hikari Gosunkugi, one of Akane's [[HopelessSuitor hopeless suitors]], is largely absent during most of the Manga/RanmaOneHalf anime and doesn't make an appearance until much later in the series. Until then, his role was usually given to Sasuke, [[CanonForeigner a character original to the anime]].
* The Bleach Musical was adapted for stage from ''Manga/{{Bleach}}'' but left out several important characters. The most important character they left out was Uryuu Ishida, who is so important to the story that the final arc wouldn't work at all if he wasn't in the story from the beginning.
* ''[[Anime/MagicalGirlLyricalNanohaAs Magical Girl Lyrical Nanoha The Movie 2nd A's]]'' left out Gil Graham and the Liese Twins, who were revealed to be behind the plot of the season. Metafictively speaking, this is because the movie is an in-universe adaptation of these events, and their roles in those events were classified.
* The ''VideoGame/SuperRobotWars'' franchise does this often, as a result of having to tell the plots of 10-20 different HumongousMecha anime all at the same time, along with the OriginalGeneration plotline. Oftentimes, characters from other anime will take up the abandoned roles, but this isn't always true.
** The recent ''Super Robot Wars OE'' reduces ''[[Anime/MobileSuitGundamWing Gundam Wing]]'' and ''[[Anime/MobileSuitGundam00 Gundam 00]]'' to just their respective main characters, Heero and Setsuna, running around in their Gundams intervening in battles. The rest of their supporting cast, including their fellow Gundam pilots, are nowhere to be found.
** In ''VideoGame/SuperRobotWarsJudgment'', the entire "[[Anime/MobileFighterGGundam Devil Colony]]" arc, as its plot comes to a halt upon [[spoiler:Master Asia's death]]. Similarly, [[Anime/MobileFighterGGundam Prime Minister Wong Yun-Fat]] (who was involved in the TV series' final arc that the final battle is based on) and [[Anime/MobileFighterGGundam Urube Ishikawa]] (whose role of manipulating Domon is partially done by Azrael) are given this.
*** In the same game, the [[Anime/{{Dancougar}} Muge Zorbados Empire]] does not exist in ''Judgment''; instead, Shapiro defects to the [[Anime/BlueCometSPTLayzner Gradosians]].
*** This is something of a recurring problem for ''G Gundam'' in ''SRW''. It never has much plot-inclusion and is mostly there to give the player some more Gundams to use. This is probably because most of the series is one long TournamentArc, which would be tough to fit into the typical war story narrative of an ''SRW'' game.
** In ''VideoGame/ShinSuperRobotWars'', the other Shuffle Alliance members are not in the game entirely. Since Gundam Wing was still airing when the game was released, Heero and Zechs were the only characters in the game.
* The [[UsefulNotes/NintendoEntertainmentSystem NES adaptation]] of the ''VideoGame/{{Strider}}'' manga omitted a few characters most notably Yuri (who serves as TheDragon to the BigBad) and the [[MadScientist Director]], who created the MindControlWeapon that's the focal point of the entire plot.
* The "Sanctuary Chapter" OVA adaptation of the Hades saga in ''Manga/SaintSeiya'' removed Harpy Valentine and Radamanthys' PraetorianGuard from the final chapters. This is specially notable for Valentine, who returns much later in the 2nd "Inferno Chapter" OVAs and references a meeting with Seiya that never happened...
* In the anime adaptation of ''LightNovel/TrinityBlood'', many characters from the novels (such as some members from the Vatican and Rosenkreuz Orden) do not appear while some have their roles reduced though some of them do appear in the manga.
* The anime adaptation of ''Manga/{{Berserk}}'' cut out the character Donovan, a mercenary who raped Guts as a child, despite a fair amount of time being devoted to Guts' childhood. This event would lead to Guts' extreme aversion to being touched, which while not completely out of character for him, does seem a bit odd without an explanation.
* The ''Anime/MobileSuitGundam'' novelizations, supposedly being what Creator/YoshiyukiTomino wanted the series to be [[MerchandiseDriven before his sponsors got through with it]], has pretty much the entire original cast of characters, [[CanonForeigner and even a few new ones]], but pares the HumongousMecha roster down to the bare essentials. The Zeons only ever use the iconic Zaku and Dom mobile suits, and a few variants thereof, as well as the telepathically controlled non-humanoid mobile armors Brau Bro and Elmeth (which gets a limited production run unlike in the series) and the massive Big Zam (which does not.) The Federation gets off considerably easier, with only the rather silly looking Guntank being cut, but then they never had very many mobile suits in the original series to begin with. It also adds the G3 Gundam from the MSV series, but that's not much considering it's only a repaint of the original.
* In ''Manga/HonooNoAlpenRose'', Madeleine [[spoiler:AKA the eldest daughter and WhiteSheep of the Toulonchamp family]] is written out of the anime.
* The short-lived manga adaptation of ''Anime/DemashitaPowerpuffGirlsZ'' omitted pretty much every major Powerpuff Girls villain except for Mojo Jojo and Princess.

[[folder:Adapted from ComicBooks]]
* [[WesternAnimation/TheFantasticFour1978 The 1978 cartoon adaptation]] of the ''ComicBook/FantasticFour'' entirely dispensed with Johnny Storm a.k.a. The Human Torch, and substituted Herbie the Robot, due to The Human Torch's rights not being available as they had been negotiated separately and were with a different company. The reason was '''not''', as is often mentioned, due to worries that children might set themselves on fire trying to imitate the Torch.
* Creator/TimBurton's ''Film/{{Batman}}'' had [[spoiler:SelfDemonstrating/TheJoker as the killer of Bruce Wayne's parents, rather than Joe Chill, the man who shot them in the original comic books. Though the other crook may be Joe Chill himself.]]
* ''Film/BatmanForever'' has [[ComicBook/{{Robin}} Dick Grayson]]'s family murdered by Two-Face, rather than Tony Zucco. Much like with Jason Todd.
* ''WesternAnimation/SpiderManTheAnimatedSeries'':
** Gwen Stacy from ''Franchise/SpiderMan'' is absent in the cartoon (save for one appearance in an AlternateUniverse.)
** The show's adaptation of ''ComicBook/SecretWars'' removed the ComicBook/XMen and ComicBook/TheAvengers, with ComicBook/{{Storm}} and ComicBook/CaptainAmerica instead serving as the lone representatives from their respective teams.
* With Peter Parker's high-school years compressed into the first third of ''Film/SpiderMan1'', you could argue that most of the villains Spider-Man fought in his early years were adapted out of Creator/SamRaimi's [[Film/SpiderManTrilogy trilogy]], for instance Electro, Mysterio, the Vulture, Kraven, and the Kingpin. Also a number of supporting characters, e.g. Mary Jane takes over Liz Allan's role at Midtown High, while her Aunt Anna is replaced by her parents. Joe Robertson's son Randy (who went to college with Peter) and Bugle staffers Frederick Foswell and Ned Leeds also drop by the wayside, and Flash Thompson, who eventually became Peter's friend in the comics, drops from sight after Peter's high-school graduation in the films.
* ''WesternAnimation/TheSpectacularSpiderMan'' had Walter Hardy, the father of Black Cat, as Uncle Ben's killer. In the original comics and most other adaptations, Ben's killer was just a generic burglar.
* ComicBook/{{Hawkeye}} is absent from both ''WesternAnimation/UltimateAvengers'' movies, despite being a major character in ''ComicBook/TheUltimates'', the series the films were inspired by.
** [[WildMassGuessing This is probably because]] Hawkeye's a ComedicSociopath in the Ultimates comics.
** ComicBook/{{Quicksilver}} and ComicBook/ScarletWitch were absent from both films as well, and were replaced by ComicBook/BlackPanther in the sequel.
* ComicBook/AntMan and ComicBook/TheWasp were left out of ''Film/TheAvengers'' and had their spots as founders taken by Hawkeye and ComicBook/BlackWidow. Creator/JossWhedon tried to include Wasp as part of the team, but had to write her out of the script.
** Whedon has also confirmed that Ant-Man will not be present in the sequel, ''[[Film/AvengersAgeOfUltron Age of Ultron]]'', despite the fact that he was the one who created Ultron in the comics. Also, while TheVision will appear, he won't be created by Phineas Horton or possess the brain patterns of WonderMan, as Horton is likely dead of old age in the [[MarvelCinematicUniverse MCU]] (a pavilion bearing his name was seen in ''Film/CaptainAmericaTheFirstAvenger''), and Wonder Man has not yet been introduced in the films. It's also unlikely that Vision will be rebuilt from the remains of the original Human Torch.
** Thanks to [[TwentiethCenturyFox Fox]] owning the film rights to the ''Film/XMen'', Whedon [[ExiledFromContinuity will also be unable to mention]] SelfDemonstrating/{{Magneto}}, the father of {{Quicksilver}} and ScarletWitch. This also means the twins can't be referred to as mutants, leading to some speculation that the two heroes might be [[TheInhumans Inhumans]] in the [[MarvelCinematicUniverse MCU]].
* Logan's childhood friend Rose was omitted from his back story in ''Film/XMenOriginsWolverine'', and much of her role in the plot was given to Sabretooth. As was Dog, Logan's half-brother.
* The BBC's radio adaptation of ''Franchise/{{Tintin}}'' adventures ''Destination Moon'' and ''Explorers On The Moon'' omit Thomson and Thompson. Consequently, Jorgen is solely responsible for the oxygen being used up too fast on the rocket.
* The character of Mort (one of Basin City's few honest cops) was written out of the cinema version of ''SinCity''. In the comics, Mort is the own who picks Hartigan up outside the prison. In the movie, this was done by Bob. (The extended version still includes a scene where Mort visits Hartigan in hospital.)
* Though he does appear near the end of the film, NickFury is replaced by CaptainAmerica as the leader of the Howling Commandos in ''Film/CaptainAmericaTheFirstAvenger''. This is likely due to the fact that Fury apparently does not possess his comic counterpart's [[OlderThanTheyLook slowed aging]] in the movies, and thus would be too young to be a veteran of UsefulNotes/WorldWar2. The fact that Fury is [[RaceLift black in the movies]] might also have complicated things given the [[BlackVikings institutionalized racism a black soldier would've faced in the 40's]].
** Baron Zemo is replaced by one of Arnim Zola's HYDRA mooks as the "killer" of BuckyBarnes.
** Pretty much every retelling of how Captain America was found and unfrozen (''Film/CaptainAmerica1990'', ''UltimateAvengers'', ''TheAvengersEarthsMightiestHeroes'', ''Film/CaptainAmericaTheFirstAvenger'') omits {{Namor}}, the one who caused his frozen body to be found in the first place.
** ''Film/CaptainAmericaTheWinterSoldier'' revealed that ComicBook/TheFalcon's winged flight suit was commissioned by the U.S. Air Force, with [[AllThereInTheManual supplementary material]] clarifying that the military ordered it from [[Film/IronMan Stark Industries]]. This is in contrast to the comics, where the Falcon's wing suit was created by ComicBook/BlackPanther.
** Barring a {{Retcon]} from future films, it would seem the three [[LegacyCharacter replacement]] Caps who filled in for Steve while he was frozen (William Nasland, Jeffery Mace, and William Burnside) have been adapted out as well.
* ''WesternAnimation/IronMan'' used the short-lived Force Works team from the comics, but replaced U.S. Agent with Hawkeye for some unknown reason.
* Every live-action depiction of ''ComicBook/TheIncredibleHulk'' omits Rick Jones, despite that character being an intrinsic element to his backstory and setting Bruce Banner up as a heroic figure willing to risk his life to save another. Interestingly, AngLee's film used a character for the same general purpose, but didn't go all the way and actually name him Jones. Likewise, the real creator of the Hulk, commie spy Igor Drenkov - who Banner told to stop the countdown but didn't - doesn't appear in adaptations with the exception of ''WesternAnimation/TheMarvelSuperheroes'', a MotionComic which used the original comic book panels.
** Betty Ross, Bruce’s eternal MoralityPet, is not brought up once in ''VideoGame/TheIncredibleHulkUltimateDestruction'', she is only mentioned offhand in her father’s, Thunderbolt Ross, file being pointed out as a relative of his; at the time the game was released Betty was dead for a long time in the Comics, and she would only come back years after the game’s release, however the game followed its own continuity by taking several comic sagas into its own narrative inspiration, Betty’s complete neglect is quite jarring.
* In the original ''Comicbook/{{Spawn}}'' comics, Al Simmons was killed by Chapel, a character from RobLiefeld's ''{{Youngblood}}'' series. Rights issues made it impossible for Chapel to appear in [[Film/{{Spawn}} the movie]], so the character Jessica Priest [[{{Expy}} was created as a replacement]].
* In the X-Men comic books:
** Magneto had an infant daughter named Anya, whose death was a major contributing factor to his fall from grace. Another important factor was that while working for the C.I.A. as a Nazi hunter in South America, he captured a Nazi war criminal the C.I.A. wanted to use for its own ends and brought him to justice; to punish him the C.I.A. killed Isabelle, Magneto's personal physician and LoveInterest. Neither Anya nor Isabelle, nor Anya's mother, Magda, appear in ''Film/XMenFirstClass'', which instead presents a missile attack from the U.S. and Soviet navies as the final reason Magneto turns to villainy. However, Magda in the comics is also the mother of Quicksilver and the Scarlet Witch, and since Quicksilver appears in ''Film/XMenDaysOfFuturePast'' with his family, it appears that Magda has some sort of counterpart in the movie universe and now one may speculate if Anya also existed there.
** In the comics, Professor Xavier was crippled by an alien named Lucifer. In the movies, he's accidentally crippled by Magneto.
* ''[[WesternAnimation/BatmanTheAnimatedSeries The New Batman Adventures]]'', ''WesternAnimation/YoungJustice'', and any other adaptation featuring ComicBook/{{Nightwing}} ignore Franchise/{{Superman}}'s role in the character's origin[[note]]In the comics, Superman gave Dick the inspiration for the Nightwing identity, as Nightwing is a hero in Kryptonian mythology[[/note]]. It's especially noticeable since the Nightwing identity [[LegacyCharacter dates back to Krypton]]!
** Although ''Young Justice'' doesn't show ''how'' Dick adopted the Nightwing persona, since it occurs some point during a five year TimeSkip. It's still possible that Superman was involved. When asked, producer Creator/GregWeisman admitted that they hadn't worked out all the details of how Dick chose the name "Nightwing."
* Similarly, in ''WesternAnimation/BatmanTheBraveAndTheBold'', Dick's becoming Nightwing is literally just Batman suggesting the name out of the blue.
* Jason Todd, the second {{Robin}}, was completely skipped over in ''WesternAnimation/BatmanTheAnimatedSeries'' and ''The New Batman Adventures''. Chunks of his origin were also given to Tim Drake, who replaced him as Batman's new partner in the show.
* ComicBook/WonderGirl was the only founding member of the Comicbook/TeenTitans not to appear in the [[WesternAnimation/TeenTitans animated series]]. This was due to the [[ExiledFromContinuity infamously convoluted rights issues regarding the Wonder Woman franchise]].
** Likewise, the original Wonder Girl, Donna Troy, is the only founding Titan not to appear in ''WesternAnimation/YoungJustice'' due to legal issues, though her successor Cassie joins the team in the second season. WordOfGod also says that Donna ''was'' a member of the team during the five year TimeSkip but had left by the time of the second season.
* The SilverAge [[ComicBook/TheAtom Atom]], Ray Palmer, retired and [[PassingTheTorch passed the mantle to]] [[AffirmativeActionLegacy Ryan Choi]] after his ex-wife Jean Loring murdered Sue Dibny during ''ComicBook/IdentityCrisis''. In ''WesternAnimation/BatmanTheBraveAndTheBold'', Palmer simply retired from crime-fighting so that he could focus on his research.
* The character of Lisa Miller is absent from the film adaptation of ''ComicBook/ScottPilgrim'', although she does appear in the animated short. Also, Wallace's boyfriend Mobile never appears in the film. While he doesn't affect the plot much directly, he does spark a fairly important subplot where Wallace decides to move in with him, leaving Scott without a place to live until he takes the plunge and moves in with Ramona. The closest the film comes to this is Wallace telling Scott to move out for no particular reason, and then [[WhatHappenedToTheMouse never bringing it up again.]]
* ''{{Film/Watchmen}}'':
** The [[spoiler:giant squid monster]] is removed, yet the backstory about its creation still seems to exist.
** Bernard and Bernie, the newspaper seller and the kid who hangs around his stand, don't appear except during the big explosion which wipes them out, making you wonder who they are. Though they are put back in the LimitedSpecialCollectorsUltimateEdition, the rest of the cast of their B-plot still either on't show up much, or are cut out entirely (as with Joey and Aline, the feuding lesbian couple).
** Dr. Long, Rorschach's prison psychiatrist, has his role cut down significantly due to time purposes. Thus, his wife and her subplot of leaving him were dropped. Rorschach's land-lady and her kids also went missing.
** Ozymandias originally had three Vietnamese servants, who would later die from him drugging their wine.
** In the comic there is a flashback where a little-seen costumed vigilante named Captain Metropolis calls together a meeting to form a group called Crimebusters. In the film, this role is given to Ozymandias, and the group's name is Watchmen. As a side note, the comic carefully avoided ever using that particular name about any group.
* Tim Drake, Onyx, and all mentions of [[Comicbook/{{Batgirl 2009}} Stephanie Brown]] are cut from ''WesternAnimation/BatmanUnderTheRedHood''. This was likely due to [[ContinuityLockOut the characters and references not being familiar with anyone but existing comic book readers]].
* In the Franchise/{{DCAU}}, Hal Jordan was never a Comicbook/GreenLantern, and his origin was instead given to Kyle Rayner. Hal and ComicBook/{{Aquaman}} were also replaced by John Stewart and Hawkgirl as founding members of the ''WesternAnimation/JusticeLeague'', though Aquaman did make [[DemotedToExtra guest appearances from time to time]].
** Hal got to make a tiny cameo in a later episode of ''JusticeLeagueUnlimited'', where he briefly replaced John thanks to a TimeyWimeyBall.
** Guy Gardner, the Green Lantern before John, was omitted as well. A mugger who looked a ''lot'' like Guy [[MythologyGag did]] [[ContinuityCameo appear]] in the episode of ''SupermanTheAnimatedSeries'' that introduced Kyle and Sinestro, but that's it.
** Barry Allen, the Silver Age Flash, also never appeared in the DCAU, though his job as a forensic scientist was given to his nephew, Wally West, who is the Flash in the DCAU. That said, both a cop in the episode "The Brave and the Bold" and Wally's boss in "Flash and Substance" resemble Barry and in the latter episode, Wally also mentions an uncle who's flying in.
* The adaptation of ''Comicbook/DaysOfFuturePast'' from the ''WesternAnimation/XMen'' animated series completely omitted Kitty Pryde. Her pivotal role in the plot was instead given to Bishop, likely due to his popularity in the comics at the time. In fact, Kitty Pryde was the only major member of the X-Men to never make any sort of appearance in the 90's cartoon. In episodes loosely based off stories she appeared in back in the original comics, her role would usually be given to Jubilee.
* While they added a lot of characters in ''Film/XMenDaysOfFuturePast'' (in the original story, only Magneto, Storm, Colossus, Kitty, and Wolverine survived while Beast and Magneto's younger self were not involved in the story), at the same time a lot of characters were removed from the original story.
** Rachel Grey and Franklin Richards are not present in the bad future, partly because Rachel's parents were dead and Franklin is tied to the Fantastic Four and thus would require too much explanation to include them; movie Kitty meanwhile, as a character from the first three X-Men films, is too young to have lived in the 1970s (in which the "past" part of ''Film/XMenDaysOfFuturePast'' is set), which means her future self could not be sent back in time to the body of her (non-existent) 1970s self.
** The film has Wolverine work with Beast and Xavier rather than the group of X-Men who worked with Kitty in the comic version (Storm, Wolverine, Colossus, Angel and Nightcrawler), and Mystique had her own Brotherhood of mutants helping her, none of whom who appear in the film. At least one of these, Pyro, is justified by being tied into the original films' timeline and so isn't born at this point, as was the X-Men team involved.
** In the comics, the X-Men had to save presidential hopeful Senator Kelly, Professor X and Moira [=MacTaggert=] from being assassinated by the Brotherhood. This is replaced by a very different plot the movie version, and Kelly and [=MacTaggert=] do not appear at all. The Senate Committee at which the assassination attempt took place in the comic version had already been used as the model for the hearing with Kelly, Professor Xavier and Jean Grey (standing in for Moira [=MacTaggert=]) in ''Film/XMen'', the very first film of the movie franchise, so there's another good reason they did not want to use that part again.
* The adaptation of ''ComicBook/SecretInvasion'' in ''WesternAnimation/AvengersEarthsMightiestHeroes'' ignored ComicBook/SpiderWoman and divvied up her role in the plot between Comicbook/{{Mockingbird}} and Comicbook/BlackWidow. ComicBook/{{Elektra}} was also omitted in favor of Viper. Also, though understandable due to the franchise having LoadsAndLoadsOfCharacters, ComicBook/{{Quicksilver}} and the ComicBook/ScarletWitch were left out as well. It's only notable since {{Hawkeye}}, who joined the Avengers in the same issue as them, and ComicBook/BlackPanther, who came much later, ''were'' included as part of the team.
* In ''WesternAnimation/BatmanTheBraveAndTheBold'', Lashina and Stompa were the only members of the Female Furies. Additionally, Mongal replaced Granny Goodness as the Furies' master. In the comics, Tatsu Yamashiro became the vigilante ComicBook/{{Katana}} after her husband and children were murdered by a {{Yakuza}} boss named Takeo. In the show, Tatsu instead became Katana after Takeo murdered her sensei Tadashi. This was mostly due the cartoon's version of Katana being [[YoungerAndHipper far too young to have been married]].
* Oroku Nagi, older brother of the Shredder, never appeared outside of the original ''Franchise/TeenageMutantNinjaTurtles'' comics, where he was a prominent part of his brother's origin. His role in the Hamato Yoshi/Tang Shen love triangle was replaced either by [[WesternAnimation/TeenageMutantNinjaTurtles2003 original character Yukio Mashimi]] or [[WesternAnimation/TeenageMutantNinjaTurtles2012 the Shredder himself]].
* The {{Animated Adaptation}}s of the first two arc of the ''ComicBook/SupermanBatman'' comics had this.
** In ''WesternAnimation/SupermanBatmanPublicEnemies'', the adaptation of the comic of the same name, the future Superman, Pete Ross, the John Stewart Green Lantern, the Super- and Bat-families, the Michael Holt Mister Terrific and the original Flash and Green Lantern were all omitted from the comic. While some were minor (Mister Terrific, Jay Garrick, and Alan Scott only appeared in a scene that led with a fight Superman and Batman had with Captain Marvel and Hawkman), three are notable: the future Superman since he figured into the sub-plot to destroy the Kryptonite meteor, Pete Ross because he was Luthor's Vice President, and John Stewart because he was the only member of Luthor's SuperTeam ''not'' to appear.
** In ''WesternAnimation/SupermanBatmanApocalypse'', based on "The Supergirl from Krypton", Bernadeth, a member of the Female Furies didn't appear, though in the comic, she spent the Furies' fight with Wonder Woman and Big Barda sitting on the sidelines with Granny Goodness. The [[ComicBook/JusticeLeagueOfAmerica Justice League]], [[ComicBook/JusticeSocietyOfAmerica JSA]], Comicbook/TeenTitans, and [[Comicbook/BatmanAndTheOutsiders Outsiders]] were also omitted from the scene at the end when Superman introduces Kara as Supergirl.
* ''WesternAnimation/JusticeLeagueDoom'' is based off Creator/MarkWaid's "Tower of Babel" story, but omits ComicBook/{{Aquaman}}, ComicBook/PlasticMan, Wally West, and Kyle Rayner, and replaces them with Comicbook/{{Cyborg}}, [[Comicbook/TheFlash Barry Allen]], and [[Comicbook/GreenLantern Hal Jordan]]. Also Ra's al Ghul was the lead villain in the original story. In the movie, he's replaced by Vandal Savage and the LegionOfDoom.
* ''Comicbook/JusticeLeagueCryForJustice'':
** Roy Harper had his arm severed by Prometheus. In ''WesternAnimation/YoungJustice'', the arm was instead amputated by generic Cadmus scientists. Also, Roy's bionic arm was created by Comicbook/{{Cyborg}} in the comics, while in the show, LexLuthor provided it.
** Maxwell Lord was the one who killed [[BlueBeetle Ted "Blue Beetle" Kord]] in ''ComicBook/InfiniteCrisis'', but in the show, Kord was murdered by Comicbook/{{Deathstroke}} and Sportsmaster.
** Paul Westfield is entirely removed from ComicBook/{{Superboy}}'s origin, with LexLuthor taking his place as Conner's creator from the very beginning.
* ''WesternAnimation/UltimateSpiderMan'' makes omits the three [[ComicBook/WhiteTiger White Tigers]] who came before Ava Ayala, instead establishing that she [[LegacyCharacter inherited the mantle]] directly from her father. It also skips over the Sons of the Tiger, a trio of martial artists who had the tiger amulet before the original White Tiger.
* ComicBook/BlackPanther's father, King T'Chaka, was killed by Klaw in the original comics, but the identity of his murderer is changed in most adaptations. T'Chaka was killed by Herr Kleiser in ''WesternAnimation/UltimateAvengers 2'', Moses Magnum in ''WesternAnimation/IronManArmoredAdventures'' and M'Baku the Man-Ape in ''WesternAnimation/AvengersEarthsMightiestHeroes'' (albeit in this last case, Klaw appears in the series and his hidden help is what allows M'Baku to kill T'Chaka).
* In ''WesternAnimation/BewareTheBatman'', ComicBook/{{Katana}} takes ComicBook/{{Robin}}'s place as Batman's traditional sidekick. The show intentionally ignores Batman's most iconic foes in favor of [[ReimaginingTheArtifact trying to raise the profile of his more obscure villains]]. For instance, Magpie and Anarky serve the roles traditionally held by Comicbook/{{Catwoman}} and SelfDemonstrating/TheJoker, with some cases bordering on outright {{Expy}} status.
* The ''ComicBook/GenerationX'' TV movie from the 90s had to omit Chamber and Husk due to budgetary reasons, replacing them with two similar characters named Refrax and Buff. Synch was also left out, but no reason was given.
* ''WesternAnimation/JusticeLeagueWar'', adapted from the first arc of the ComicBook/{{New 52}}, ''Justice League: Origins'', replaced ComicBook/{{Aquaman}} with ComicBook/{{Shazam}}.
* ''WesternAnimation/SonOfBatman'' cuts out any Robin that wasn't Dick Grayson (Robin I) and Damian Wayne (Robin V). Aside from the lack of anyone mentioning any other Robin (which could be just that), there are few others ways this can be noticed. Jason Todd (Robin II) is removed as there's no costume monument in the Batcave (which was placed there after he died), and the Lazarus Pits are unable to revive Ra's al Ghul after he was caught in an explosion. Jason was caught in even ''closer'' proximity to an explosion and was revived with a Lazarus Pit. Tim Drake (Robin III) clearly does not exist, since in the comics, Damian usurps the role of Robin from him. Here, there's nothing to suggest there's an active Robin.
* The ''WesternAnimation/HulkAndTheAgentsOfSMASH'' episode "Inhuman Nature" retells the Comicbook/FantasticFour's first encounter with TheInhumans, but with the Agents Of S.M.A.S.H. replacing the FF. A-Bomb is even given the Human Torch's romance plot with Crystal.
* Silver Samurai and Sunfire do not appear in ''Disney/BigHero6'', as the film rights to the ''Film/XMen'' franchise are owned by TwentiethCenturyFox, not Disney or Marvel. Not that they would fit in anyway, since the film's world is now a more tech-based sci-fi world, and mutants with superpowers would seem very out of place.
* The Novelization to ''ComicBook/TheDeathOfSuperman'' yanks out just about ''everyone'' in the DC Universe save for the lineup of the Justice League at the time, Wonder Woman and Batman. This also includes Green Lantern Hal Jordan, who is very a big part of the finale due to the destruction of Coast City.
* In ''Film/TeenageMutantNinjaTurtles2014'', [[spoiler:Hamato Yoshi is nowhere to be seen in this story, with Splinter a mutated rat (not Yoshi himself) who learned ninjitsu from reading books on it. Oroku Saki is not named on camera, but the character himself embodies the name of The Shredder]]. Casey Jones is not in the film as well, despite being in [[Film/TeenageMutantNinjaTurtles the parallel first movie.]]
* ''Series/AKAJessicaJones'' swaps out [[MsMarvel Carol Danvers]] for Patsy Walker as Jessica's best friend. This is because Carol is going to be the subject of the upcoming ''Captain Marvel'' movie, and Marvel likely wanted to avoid any potential conflict.

[[folder: Adapted from Film]]
* Carl the friar is absent in the tie-in videogame adaption of ''Film/VanHelsing''. So is Chas Kramer from the ''Film/{{Constantine}}'' tie-in game.
* When ''Film/TheProducers'' was adapted into a stage musical of the same name, Lorenzo St. [=DuBois=], a hippie nicknamed LSD, was given this treatment. In the original film, he walks into the ''[[ShowWithinAShow Springtime for Hitler]]'' auditions by mistake and is chosen to play Hitler by virtue of his utter lack of talent. LSD's SoBadItsGood performance as Hitler plays a large role in [[SpringtimeForHitler the play's unintentional and unwanted success]]. In the musical, Franz Liebkind is chosen to play Hitler, but Roger De Bris is the one to perform the role onstage after Franz breaks his leg.
* The TV version of ''{{Series/MASH}}'' drops Duke Forrest, Tom Skerritt's character in [[{{Film/MASH}} the film]], in order to tighten up the cast. Additionally, some of the film's supporting characters (Spearchucker, Lt. Dish, Ho-Jon, etc.) make scattered appearances in the first season, but were all [[ChuckCunninghamSyndrome Brother Chuck]]ed by the second season.
* The LicensedPinballTable for ''Pinball/BramStokersDracula'' omits Mina Murray and Jonathan Harker completely, as neither Winona Ryder nor Keanu Reeves would allow their likenesses to be used. Aftermarket plastics with their images based on prototypes are available, however.
* Similarly, ''Pinball/{{Apollo 13}}'' is completely devoid of Creator/TomHanks, the star of the film. The closest substitute is the astronaut on the backglass, whose face is covered by a OneWayVisor.
* In the Junior Novel version of ''WesternAnimation/TheLegoMovie'', [[spoiler:all of the live-action characters]] are excluded from the film, as is [[spoiler:the plotline with Finn and his father]].
** Similarly, ''The LEGO Movie Videogame'' [[spoiler: keeps Finn, but leaves out everything regarding his father, The Man Upstairs, including taking out his {{foreshadowing}} in Emmet's opening vision.]]
* Omni Consumer Products, the company that turned police officer Alex Murphy into the titular cyborg in the ''Franchise/RoboCop'' film series, is nowhere to be seen in ''RoboCopAlphaCommando''.
* Power Records's book and audio record adaptaion of ''Film/EscapeFromThePlanetOfTheApes'' omits Dr Milo. Zira and Cornelius are instead the only occupants of the spaceship and it is Cornelius who susses out that he and Zira have travelled back in time.
* ''VideoGame/GhostbustersPinball'' is a DigitalPinballTable based on the [[Film/{{Ghostbusters}} first two movies,]] yet Vigo the Carpathian is nowhere to be found.
* When the events of ''Disney/{{Frozen}}'' were incorporated into season 4 of ''Series/OnceUponATime'', the important human characters - Anna, Elsa, Kristoff, and Hans - were brought over. Sven also was brought over. But Olaf is noticeably absent, and the events at the end of ''Frozen'' seem to have been changed so that Hans is still on the loose looking for new schemes to take over Arendelle (perhaps he escaped from the boat that was meant to ship him back to the Southern Isles). A probable reason for Olaf's absence is due to him being pretty superfluous and, meta-wise, too difficult to have around in terms of special effects.
* Creator/{{Sega}}'s ''Pinball/SpaceJam'' {{Pinball}} game is notable for completely omitting Lola Bunny, the BaseBreaker character from the film.

[[folder: Adapted from Literature]]
* Numerous characters in the [[Film/HarryPotter film versions]] of ''Literature/HarryPotter''. Some do not appear at all (such as Peeves the poltergeist), some are absent in earlier films, but show up later when they're important with an explanation as to why they've been absent (such as Bill and Charlie Weasley) and some appear in earlier films but are absent in later ones (such as Nearly Headless Nick and Firenze). The same thing happens in the [[VideoGame/HarryPotter video games]], but since there are multiple versions of each game for different platforms (there are five different versions of the first game alone), nearly every non-major character is absent from one game or another without explanation, which leads to apparent cases of RememberTheNewGuy in later games.
* {{Twilight}} ended up cutting several of the human characters and PairTheSpares by having two characters who had their love interests taken out with each other.
* Examples from the various adaptations of ''Literature/LordOfTheRings'':
** Tom Bombadil and his wife Goldberry, together with the Hobbits' entire "Old Forest" adventure, are absent from both film adaptations made so far.
** Glorfindel is absent in both adaptations, too: In the [[Film/TheLordOfTheRings Peter Jackson films]], his role of rescuing Frodo from the Nazgűl and bringing him to Rivendell is given to Arwen. In [[WesternAnimation/TheLordOfTheRings Bakshi's animated adaptation]], his role is given to Legolas.
** Similarly, Prince Imrahil who plays a major role in ''The Return of the King'' is omitted entirely from both the Jackson and the Rankin/Bass version. In the books his role supporting Gandalf's defense of Minas Tirith and his support of Aragorn as King of Gondor are fairly important plot points, as he's the one that figures Aragorn can cure victims of the Nazgűl.
** Beregond is cut from most adaptations. His (and his son's) role as Pippin's friend is [[CompositeCharacter given to Faramir]] in the Jackson films. His role in defending Faramir from premature cremation is simply cut from the same, so Pippin's dash for Gandalf is even more desperate and they only get there ''just'' as the pyre is about to be lit. Purportedly, [[http://tolkiengateway.net/wiki/Beregond_%28soldier_of_Gondor%29#Portrayal_in_Adaptations Ian Hughes']] character was meant to be Beregond, but the name was changed in post-production because the role had been so reduced. ([[AllThereInTheManual Not that you hear either name said onscreen.]])
** Ghan-buri-Ghan and Elrond's sons Elladan and Elrohir are also absent from the Peter Jackson film. Quickbeam the Ent appears in the crowd shots, DemotedToExtra.
* Scarlett O'Hara's children from her first two marriages, Wade Hampton Hamilton and Ella Lorena Kennedy, appear not to exist in the film adaptation of ''Film/GoneWithTheWind''.
* Rita Blakemoor from ''Literature/TheStand'', who was merged into a CompositeCharacter with Nadine. Elements of Nadine's character (particularly the presence of Joe) were also merged with the Lucy character. Fran's mother is dead in the beginning of the TV adaptation. And Dayna is also a CompositeCharacter with another minor character.
* Madge Undersee and her family do not appear in the film versions of ''Film/TheHungerGames'' probably due to casting logistics and length constraints. Katniss instead gets the mockingjay pin (now lacking its BackStory involving Maysilee Donner) from a vendor at the Hob.
* There was a fourth son in ''Literature/TheSwissFamilyRobinson'' book. He got dropped from the Disney movie.
* The ''Literature/WarriorCats'' graphic novel trilogy ''[=SkyClan=] and the Stranger'' (and bonus manga at the end of [=SkyClan=]'s Destiny) is unique among ''Warriors'' mangas in that they try to make ''all'' [=SkyClan=] cats appear, or at least be ''mentioned''. While almost the entire Clan ''is'' in there, the only ones to not show up or be mentioned at all in either the trilogy or the bonus manga are Sagepaw and Egg, for whatever reason.
* Examples from adaptations of ''Literature/AlicesAdventuresInWonderland'':
** Disney's ''Disney/AliceInWonderland'' adaptation leaves out the Duchess, Fish Footman, the Frogman, the cook, the pig baby, the Gryphon and the Mock Turtle (although sequences were storyboarded for those characters) and replaces Pat with the Dodo. The Gryphon and the Mock Turtle were dropped for being "too talkative" (or words to that effect). Earlier drafts omitted Alice's sister.
** Jan Svankmajer's ''Film/{{Alice}}'' omits the Gryphon, the Mock Turtle, the Cheshire Cat and replaces the roles of the Duchess and her cook with the White Rabbit.
** Burbank Films's 1988 ''WesternAnimation/AliceInWonderland'' has the Dodo show Alice the Mock Turtle as opposed to the Gryphon.
** In ''[[Literature/AlicesAdventuresInWonderland Through The Looking Glass]]'', after ringing the bells for the castle, Alice is greeted by a frog. He is omitted in the [[Film/AliceInWonderland1985 1985 TV movie]]. The food whom Alice is introduced to are both absent, perhaps because the writers needed more time for the sequence with the Jabberwocky. Dinah's kittens are also absent due to the story being adapted to take place directly after Alice's trip to Wonderland (as opposed to 6 months later).
** The BBC's 2012 audio adaptation of ''Through the Looking-Glass'' omits Lily. So when Alice asks why she is being assigned the role of White Pawn, the Red Queen tells her to shut up.
** The Red Knight is often left out of adaptations of ''Through the Looking-Glass''. Alice just meets the White Knight without encountering the Red Knight in the first place.
** Dinah and the kittens are absent in the 1998 ''Film/ThroughTheLookingGlass'' film. The story is instead bookended with Alice reading the ''Through the Looking-Glass'' book to her daughter.
* ''Gor'', the film version of ''Tarnsman of Literature/{{Gor}}'', adapts out Tarl's father Matthew, the Older Tarl (Tarl's instructor at arms), Torm the Scribe, Tarl's sword brother Kazrak of Port Kar, the slave girl Sana, Nor the (sentient) spider, Pa-Kur the Master Assassin, Mintar the Merchant, and Tarl's tarn Ubar of the Skies.
* ''Dirk'', the stage adaptation of ''Literature/DirkGentlysHolisticDetectiveAgency'', drops the Monk and his horse, partly to simplify the timeline of events (in the novel, the Monk spends most of the story off on his own doing things that only become significant in retrospect) and partly because incorporating a live horse was beyond the resources of the theatre that originally staged it.
** The pilot episode of ''Series/DirkGently'', based very loosely on the book, also skips the Monk and his horse. And Professor Chronotis. And Michael Wednesday-Week. And the alien. And ... look, it's got Dirk, Richard, Susan and Gordon.
* Due to the novel having LoadsAndLoadsOfCharacters, Terrence Malick's ''TheThinRedLine'' fails to feature several major characters, including Queen the Texan.
* In the animated adaptation of ''Literature/TheChroniclesOfNarnia'' adventure ''The Lion, The Witch and The Wardrobe'', Father Christmas does not appear. Instead Aslan gives the children their weapons. That was also the original plan for the 2005 film before someone designed a Father Christmas who looked more suited to the story.
* Several characters are taken out of Disney's [[Disney/TheJungleBook adaptation]] of ''Literature/TheJungleBook'', perhaps most notably Tabaqui the Jackal. Most of them do not appear in the live action adaptation either (though the second more loyal sequel ''Mowgli's Story'' features Tabaqui and a few others).
* It's not exactly an adaptation, but Bagheera and Kaa don't get roles in ''WesternAnimation/{{Talespin}}''.
* ''Literature/{{Discworld}}'':
** Hrun the Barbarian from ''Literature/{{Discworld}}'' doesn't appear in SkyOne's ''Film/TheColourOfMagic''.
** Professor Pelc, Prehumous Professor of Bibliomancy, doesn't appear in their adaptation of ''Discworld/GoingPostal''.
** Other people omitted from the ''Going Postal'' adaptation are Anghammarad the ancient golem, [[OddJobGods Anoia the Goddess of Things That Stick in Drawers]], most of the Grand Trunk's board, and (by implication) the Guild of Assassins.
** The stage adaptation of ''Discworld/{{Mort}}'' skips the Librarian due to the difficulty the original production had getting an orang-utan costume. It also replaces Rincewind with a wizard called Stibbons (before Ponder appeared in the books) so they could use a "generic" wizard costume rather than Rinso's canonical outfit.
* ''Literature/WatershipDown'': Mainly due to AdaptationDistillation, rabbits not appearing in the film of the book include:
** ThoseTwoGuys (three actually) Hawkbit, Speedwell and Acorn
** PluckyComicRelief Bluebell
** Strawberry, a refugee from Cowslip's warren
** Hyzenthlay's friend Thethuthinang and Nelthilta, the turncoat doe
** Plus the mouse Hazel rescues from a hawk on Watership down, who is actually the character in the book that informs the rabbits that the Efrafans have gathered below the down and are planning to attack.
* From ''Literature/{{Wicked}}'': Liir, Sarima, Nor (and the rest of the family), Nanny, and Yackle (and the rest of the nuns), as well as less important characters like Sir Chuffrey (Glinda's husband) and Shell (Elphaba's brother).
* In the cartoon adaptation of ''Literature/AnimalFarm'', Mollie and Clover are absent. Benjamin the donkey fills in for Clover, if anything.
* The original 1902 stage version of ''Literature/TheWizardOfOz'' removes the Wicked Witch and Toto (who was replaced with a cow named Muriel).
** The 1925 InNameOnly movie version, in addition to changing almost the entire plot, takes this UpToEleven and removes everyone except for Dorothy, the Tin Woodman, the Cowardly Lion, the Scarecrow, Auntie Em, Uncle Henry, and the Wizard. Characters loosely based on those from later books appear in place of the omitted characters.
** In the original novels, Glinda was the Good Witch of the South, and the Good Witch of the North Dorothy met when she first arrived in Oz was a different character. The film version [[CompositeCharacter combined the two into a single character]]... Named Glinda. Due to AdaptationDisplacement, most subsequent adaptations have also had Glinda as the only Good Witch.
** Ozma seems to have fallen victim to this in ''WesternAnimation/LegendsOfOzDorothysReturn'', if the Scarecrow and his friends being in charge of Oz is anything to go by.
* Early ''[[WesternAnimation/ThomasTheTankEngine Thomas and Friends]]'' episodes omitted many one shot or background characters used in ''TheRailwaySeries'' novels they were adapted from, with Thomas or some other recurring engine taking their place. Jinty and Pug are absent in episodes adapted from "The Eight Famous Engines" for example, while, due to lacking budget for a model of The Flying Scotsman, "Tender Engines" was loosely adapted from "Tenders For Henry", with only the engines' tenders being shown in a cameo.
** Numerous characters from the books (including the Mountain and Small Railway Engines) will also never appear in the television series now that it has broken away from ''Literature/TheRailwaySeries''.
* When ''Literature/TheRelic'' was adapted to [[Film/TheRelic film]], Literature/AgentPendergast was written out and Lieutenant D'Agosta was promoted into his role. Pendergast became the BreakOutCharacter of the novel and is featured as the main character of all the novels that follow. The series is informally titled "The Agent Pendergast Series."
** William Smithback, a reporter and recurring character in the Pendergast novels, was also cut from the book, though unlike Pendergast his character traits weren't given to anyone.
* The movie version of ''Franchise/JurassicPark'' leaves out the character of publicist Ed Regis. The character of Gennaro in the movie is a CompositeCharacter of him and the book's Gennaro.
* ''Literature/TheCiderHouseRules'', whose adapted screenplay was written by the novel's author, leaves out Melony entirely.
* In ''Literature/AChristmasCarol'', the Ghost of Christmas Present shows Scrooge two children named Ignorance and Want, whom Scrooge must avoid. A few adaptations don't have the Ghost show Scrooge the children.
* In most adaptations of ''Literature/OliverTwist'', including the musical version ''Oliver!'', Monks and the Maylies are omitted. In Alan Bleasdale's mini-series, Monks and Rose Maylie are retained, but Rose (who retains her original name Rose Fleming) is now Mr. Brownlow's ward.
* The TV movie adaptation of ''TheWestingGame'' lacks Theo Theodorakis, Flora Baumbach, Dr. Denton Deere, and Madame Hoo.
* Beorn, Bolg, Roäc, and the Master of Lake-town are absent from the animated film of ''WesternAnimation/TheHobbit''.
* Bound to happen with ''Literature/LesMiserables'' as it's difficult to adapt a 1500-page book into anything remotely watchable without cutting several characters. The Thenardiers and their children are hit with this often.
** M. Gillenormand frequently gets the ax as well, although after being cut in [[Theatre/LesMiserables the musical]], he was restored in [[Film/LesMiserables2012 the film of the musical]].
* Obviously the amount of characters that encompass ArthurianLegend is immense, and ''Series/{{Merlin}}'' was never going to fit them ''all'' in (in fact, they did the now-rare move of separating the characters Morgana and Morgause, who in many adaptations are combined into a CompositeCharacter), but there were a few key characters that never appeared: Elaine, Galahad and Kay. These three in particular usually make it into other adaptations, and fans of the show often commented on their absence here.
* The original novella ''TheStrangeCaseOfDoctorJekyllAndMrHyde'' is a sort of detective story, and the central character is the AmateurSleuth Mr Utterson. As adapatations typically drop the mystery aspect, his character tends to get Adapted Out or [[CompositeCharacter merged with Dr Lanyon]].
* In order to concentrate on the main love triangle, the musical version of ''Theatre/ThePhantomOfTheOpera'' left out several side characters, most notably Raoul's older brother Philippe and the mysterious Persian--the latter's function as Raoul's guide into the Phantom's realm was [[CompositeCharacter assumed by Mme. Giry]].
* The film adaptations of ''Film/PercyJacksonAndTheOlympians'' have a few. ''The Lightning Thief'' left out several characters, and this notably includes [[spoiler: Ares and Kronos]], two major antagonists of the book and in the latter's case, the BigBad of the entire series. Other characters like Clarisse and Dionysus were also left out. The sequel makes Clarisse, Dionysus [[spoiler:and Kronos]] appear, but Circe got the shaft this time.
* At least one film adaptation of the first book of ''Beau Geste'' left out a particular character who in subsequent books was revealed to be plot-critical in the original book.
* Given that the original books are edging on [[{{Doorstopper}} doorstoppers]], it's understandable that several characters would be missing from the film adaptations of Literature/TheVampireChronicles. Not only minor characters got ignored, though:
** Film/InterviewWithTheVampire axes Louis' younger brother Paul, whose death was the catalyst for Louis' [[DeathSeeker suicidal depression]] in the beginning of the book, replacing him with a brief mention of a dead wife and child who didn't exist in the books. An entire subplot regarding a woman named Babette who Louis secretly advises in running her family was also dropped.
** Film/QueenOfTheDamned is much more liberal with the axe. Louis and Nicolas are both entirely absent, despite being Lestat's love interests and, especially in Nicolas' case, integral to the plot. (It was his violin Lestat played to wake Akasha.) Daniel is also dropped, leaving Armand DemotedToExtra as his plotline revolved mostly around Daniel. Mekare is also missing, apparently having become a CompositeCharacter with her sister Maharet, and Khayman is nowhere to be seen, as much of the backstory was dropped to focus on the modern plot. The Talamasca agent Aaron Lightner has also been removed from the film, with his role as Jessie's mentor being taken over by the CompositeCharacter David Talbot.
* If you like ''Literature/JourneyToTheWest'', you probably know that you'll have a hard time finding any adaptations which don't cut down his role or just remove him entirely, but ''VideoGame/EnslavedOdysseyToTheWest'' does that ''and'' removes Sha Wujing.
* As an adaptation of a [[Literature/ASongOfIceAndFire book series]] with LoadsAndLoadsOfCharacters, ''Series/GameOfThrones'' has a fair number of [[CompositeCharacter Composite Characters]] as well as a fair number of minor characters who have been adapted out completely.
** The most notable example is Jeyne Westerling who has been removed in favor of CanonForeigner Talisa Maegyr - the Westerlings are still mentioned, but have no story significance unlike the books.
** Comments by one of the actors suggest that the character Lady Stoneheart may not be appearing in the TV series either, though it's too early to be sure.
** The Brave Companions are another example. Jaqen, Rorge, and Biter join the Lannister army instead. Their roles after they go over to Roose Bolton are replaced by a group of Bolton men-at-arms led by Locke, Bolton's Dragon.
** Willas and Garlan Tyrell's roles have been delegated to either Loras or Margaery.
** Stannis' main supporters in House Florent (minus his wife) do not appear.
** Cersei's Hired Swords, the brothers Kettleblack are not in the TV series, as is Coldhands. Another example is Barristan Selmy's traveling companion Strong Belwas.
* Margot Verger is entirely absent from the film adaptation of ''[[Literature/TheSilenceOfTheLambs Hannibal]]'', and as a result the manner of death for [[spoiler:her brother, Mason]] changes considerably between the two, since she killed him in the original book.
** Alan Bloom is given only a minor part in ''Film/{{Manhunter}}'' and completely left out of the Hopkins / Norton take of ''Film/RedDragon''. Inverted in ''Series/{{Hannibal}}'' where he's gender swapped and turned into ''Allana'' Bloom, who becomes a major supporting character and Grahams' potential love interest. Ditto Margot Verger, who appears in season 2. Since the show is a lengthy prequel to the original story, both they and every other character get ''greatly'' expanded roles.
* Julia and her sister are entirely absent from the movie version of ''MySistersKeeper''. Julia's absence leads to an entire romantic subplot between her and Campbell being cut, substantially reducing Campbell's screen time.
* ''Literature/CharlieAndTheChocolateFactory'' has LoadsAndLoadsOfCharacters on the Golden Ticket tour as written, but many of the adults have dialogue/plot functions that are easily handed to others. Depending on the adaptation, some are DemotedToExtra, and others fall under this trope.
** [[Film/WillyWonkaAndTheChocolateFactory The 1971 film adaptation]] dropped Mr. Bucket (Charlie's dad), with him suffering DeathByAdaptation before the main action starts.
** [[Film/CharlieAndTheChocolateFactory The 2005 film]] drops Mr. Beauregarde and Mrs. Teavee.
** ''Theatre/TheGoldenTicket'' (an opera) drops ''both'' of Charlie's parents, Mr. Gloop, Mrs. Salt, Mrs. Beauregarde, and Mr. Teavee.
** [[Theatre/CharlieAndTheChocolateFactory The 2013 stage musical]] drops Mrs. Salt and Mrs. Beauregarde -- both Veruca and Violet are rather clearly [[DaddysGirl daddy's girls]] for the change -- though the latter is mentioned in passing in Violet's introductory song.
* Mike Nichols' film adaptation of ''Literature/CatchTwentyTwo'' drops several of the LoadsAndLoadsOfCharacters, including Major [[SpellMyNameWithABlank _____]] de Coverley, Chief White Halfoat, and Ex-PFC Wintergreen.
* ''TwentyThousandLeaguesUnderTheSea'': The character of Conseil is often left out. The notable exception is the Disney version where he's played by PeterLorre. In some more recent adaptations, Conseil is replaced by [[CanonForeigner Professor Arronax's daughter]].
* ''Literature/TheSookieStackhouseMysteries'' TV adaptation, ''Series/TrueBlood'', completely left Bubba out of the show. Though, to be fair, ''True Blood'' started to diverge from the book storylines right around the point Bubba would have been introduced.
* Anime/OnegaiSamiaDon is an AnimatedAdaptation of the book Literature/FiveChildrenAndIt, but the eldest daughter Althea isn't included in the series and CanonForeigner Anne Hopkins takes her in-story spot.
* In the theatrical adaptation of ''Jingle Bells, Batman Smells, P.S.: So Does May'' from the ''Literature/JunieBJones'' books, Junie B.'s little brother Ollie is mentioned, but not actually seen. Likely true for the productions of other titles from the series as well. This is most likely because all of the children are played by real kids and it would be more trouble than it's worth for a production of this type to try to cast a kid that young.
* ''[[Film/TheHungerGamesMockingjay The Hunger Games: Mockingjay Part 1]]'':
** Enobaria is not mentioned here.
** Fulvia and the prep team aren't present due to their roles being taken by Effie.
* Minor characters like Kaitlyn, Lydia and Gus' sisters are not present in ''Film/TheFaultInOurStars''. Van Houten gives Augustus' eulogy to Hazel personally, while Isaac fills the slightly comedic relief role. Some other scenes are also cut to improve the flow (and shorten the length) of the film. Creator/JohnGreen's cameo as the parent of Jackie, the little girl who wanted to try on Hazel's cannula, was also cut.
* In ''Film/VampireAcademy'', this is the fate of several minor characters of [[Literature/VampireAcademy the first novel]]:
** Jeremy, a human housemate of Rose and Lissa, is adapted out. So is the scene where Lissa uses compulsion to convince him to hand over his car keys.
** Teacher Stan Alto is also missing, along with the scene where he publically grills Rose for details on her guardian methods.
** Xander Badica is missing, along with the scene where he asks to taste the blood of Rose.
** The dhampirs Anthony and Mile are missing, along with the scene where they try to force Rose to sleep with them.
** The most important character missing is probably Eddie Castile, Mason Ashford's best friend. He only appears as a party boy in the original novel. He would receive more meaningful roles from ''Frostbite'' onwards, becoming one of the most important supporting characters.

[[folder: Adapted from Live Action TV]]
* In the original ''Series/GetSmart'' series final season Max and 99 had twins, a boy and a girl. In the 1995 revival series only the (now adult) son is shown, and there's no mention at all of his sister.
* In the ''[[Series/TheBradyBunch Brady Bunch]]'' AnimatedAdaptation ''WesternAnimation/TheBradyKids'' Alice and the parents don't appear, and the dog Tiger is replaced by Moptop.
* The ''Literature/RedDwarf'' novel ''Infinity Welcomes Careful Drivers'' replaces Captain Hollister with a female captain named "Kirk".
* The novel of ''Series/KamenRiderDecade'' omits the Hikari Photo Studio and its owner Eijiro, Natsumi's grandfather. In the series, Tsukasa and friends travel between worlds by changing the backdrop in the studio; in the novel they simply use Tsukasa's camera. Sayo, Tsukasa's sister from TheMovie, also does not exist in the novel.
** The novel has Tsukasa visit the original ''Series/KamenRider'' worlds as opposed to SuspiciouslySimilarSubstitute counterparts, which means Yusuke Onodera (the alternate Series/KamenRiderKuuga) is gone. Since the novel stops after they've visited the nine Heisei Rider worlds, anything that happens afterwards (including the Showa Riders and the CrossOver with ''Series/SamuraiSentaiShinkenger'') is gone too.
* Nurse Christine Chapel, one of the main characters from ''Series/StarTrekTheOriginalSeries'' (and one of only two female leads), is TheUnseen in ''Film/StarTrek2009'' ([=McCoy=] does name-check her but she is not actually seen on-screen), presumably so Uhura can benefit more from TheSmurfettePrinciple. Chapel's absence is {{Handwaved}} in ''Film/StarTrekIntoDarkness'', but even though this confirmed that at least she still exists and is alive in-universe, it didn't go over too well with fans.

[[folder: Adapted from Newspaper Comics]]
* ''WesternAnimation/GarfieldAndFriends'' removed Blue and Cody from the ''ComicStrip/USAcres'' cartoons. Also, in a rather odd example, [[http://www.youtube.com/watch?v=pGLVl5WEf5g one]] ''U.S. Acres'' quickie was an adaptation of [[http://www.garfield.com/usacres/vault.html?yr=2010&addr=100803 this]] comic, but it removed Sheldon.
** Arlene, Garfield's (ir-)regular girlfriend from [[ComicStrip/{{Garfield}} the strip]], was also missing from the show. Reportedly, this was at creator Jim Davis's request – [[ExecutiveMeddling the suits apparently wanted her acerbic personality toned down]] ([[ArsonMurderAndJaywalking and they disliked her buck-teeth]]) and Davis was unwilling to allow the changes. Garfield eventually got a different girlfriend, [[CanonForeigner Penelope]], later in the cartoon's run.
** Every woman other than Dr. Liz Wilson that Jon dated or attempted to date is also absent, in favor of playing up Jon's futile attempts to woo Liz.
** The unnamed Spiders (whose antics fill many a Sunday strip) are missing, though mostly because those strips only became commonplace after the cartoon ended.
* [[WesternAnimation/BabyBlues The cartoon version]] of ''ComicStrip/BabyBlues'' got rid of Hammie and Wren, as it focused on when Zoe was a baby and neither were born yet.
* Michael Caesar is completely absent from ComicStrip/TheBoondocks cartoon series, despite being Huey's best friend and the second most frequently seen character in the comic strip.

[[folder: Adapted from Radio]]
* In the original BBC radio version of ''The Flight of the Conchords'', the optimistic New Zealanders trying to make it big in Britain have an even more optimistic CloudCuckoolander manager, played by Welsh character actor Rob Brydon. Sadly, the magnificent Brydon who did so much to make the radio series work is dropped completely from the TV adaptation.

[[folder: Adapted from Tabletop Games]]
* The animated adaptations of the ''QueensBlade'' gamebooks took some liberties towards some characters and plot events:
** Hans (Hobby Japan's collective WordOfGod and AuthorAvatar) does not appears in the animated TV series, but he appears in the CD dramas and the videogames, His role is replaced in the anime by [[CanonForeigner The Head Archangel]] instead.
** Nyx doesn't appear in the first season, as the producers of the anime seems to run out of episodes for including her (other than a brief cameo), not to mention she's not very important, plot-wise, for the story (despise having a designated voice actress). She appears in the second season for real.
** Alice, the main protagonist of the ''Queen's Gate'' novels and gamebooks, only appears in the ''Queen's Gate Spiral Chaos'' game and she doesn't appear in the anime. Also, neither her friends nor her family in Europe and her backstory from the novels are mentioned anywhere in the game.
** While she is a crossover character in the ''Queen's Gate Spiral Chaos'' game, [[VideoGame/BlazBlue Noel Vermillion]] is the only character from her universe who appears, and despise being mentioned in the game and being the main motivation for her for being in the game, Jin Kisaragi doesn't not appear in the game. This is somewhat egregious, as while the events of the game are not canon for the ''VideoGame/BlazBlue'' universe, both characters are vital for [[spoiler:Hazama aka Yuuki Terumi]] for his plans to work and he's not mentioned anywhere.
** Also, none of the characters from the ''Sword of the Unicorn'' novels appears anywhere, as the events of those novels are not canon, since the novels took some liberties with the already established backstory. (For beginners, there's ''no QB tournament here'')

[[folder: Adapted from Theater]]
* In the UK version of ''WesternAnimation/{{Shrek}}: The Musical'', The Magic Mirror is absent. Instead, Lord Farquaad gets the information he needs from The Gingerbread Man. A couple of fairy tale characters were also left out and replaced with characters that would be more recognisable to the UK audience.
** The Magic Mirror also tends to be cut when it is performed in community theaters, because the Magic Mirror uses motion capture and most theaters can't afford that. Gingy, like above, gives the information.
* There were originally six greasers in ''{{Grease}}'', but the number was shortened to five when the show was tweaked for Broadway audiences. The principal of Rydell High and a few other characters were also cut. A remake of this version (titled ''The Original Grease'') was produced in 2011 and re-instated some of the scrapped characters, with the exception of the principal.
* The film version of ''Film/PaintYourWagon'' removed Ben's daughter Jennifer and her LatinLover Julio, who were the ''primary couple'' in [[Theatre/PaintYourWagon the original show]].
* The film version of ''Theatre/{{Camelot}}'' eliminated Nimue and Morgan le Fey, both of whom appeared in one-scene each in the original play. Morgan le Fey is also absent from many modern productions.
* TheMusical version of ''Theatre/{{Chicago}}'' eliminated the role of Jake, a reporter who served as the AudienceSurrogate.
* In the film version of ''Theatre/OnTheTown'', Claire's fiancé Pitkin is absent, which serves to remove the adulterous implications of her affair with Ozzie.
* The film version of ''Theatre/AnimalCrackers'' entirely eliminated the part of Wally Winston, a society gossip columnist (who, like many other such characters from contemporary plays and movies, was a NoCelebritiesWereHarmed version of Walter Winchell). His love interest, Arabella, was made a CompositeCharacter.
* Rooster and Lily, Hannigan's brother and his significant other, are two major antagonists who are cut from the 2014 version of ''Film/{{Annie|2014}}''. Considering their role in [[Theatre/{{Annie}} the source musical]] as the ones who act as Annie's fake parents, [[RaceLift that wouldn't necessarily work out here.]] Their part in [[VillainSong "Easy Street"]] is given to Guy.
* ''Film/IntoTheWoods'':
** The Narrator. The majority of his lines are now said by the Baker through a voice over. (This works in favor of the film's ending.) Cinderella's drunkard father is also said to have [[DeathByAdaptation passed away]] shortly after marrying her stepmother. And, for obvious reasons, Snow White and Sleeping Beauty don't get their cameos like in the musical; Cinderella's Prince is still a cad, but Disney probably didn't want to make two of their leading ladies into TheMistress.
** Rapunzel's twins were cut. They wouldn't make sense in the compressed time-frame, contributed little to the plot, and [[WhatHappenedToTheMouse disappeared during Act Two]].

[[folder: Adapted from Toys]]
* Each and every Transformers toyline has characters that aren't added to the TV shows, comics, or movies.
** The G1 cartoon had the Monsterbots and the Duocons (as well as the toys made for the original line after the show was cancelled).
** Almost all Generation 2 characters, especially the PAL-region exclusive figures.
** WesternAnimation/BeastWars had several dozen examples, as did BeastMachines.
** Many of these characters were eventually used throughout the ExpandedUniverse, or in other media. However, some characters have [[http://tfwiki.net/wiki/Category:Toy-only_characters never made the jump to fiction]].
* This also applies to every generation of the ''Franchise/MyLittlePony'' franchise to be adapted.
** The current fourth iteration of the toyline has Lily Blossom, a Pegasus with a unique design (something normally reserved for major characters) who was part of the early wave of releases along with the six leads from [[WesternAnimaton/MyLittlePonyFriendshipIsMagic the TV series]], yet has never appeared in the show.
* The ''Film/MastersOfTheUniverse'' film dumped Orko for a stand-in character who filled the same role in [[Franchise/MastersOfTheUniverse the franchise]]. This is HandWave[=d=] when one of the titular Masters claims that Skeletor has captured a number of their allies.

[[folder: Adapted from Video Games]]
* The live action film version of ''[[VideoGame/TheKingOfFighters King of Fighters]]'' omitted the vast majority of the cast, in favor of focusing on Kyo, Iori, Mai, Terry, and Rugal.
* The featureless player character from ''VideoGame/KantaiCollection'', The Admiral, was not made into a leading character or someone with known features in [[Anime/KantaiCollection the Anime]]; he is an unseen figure instead, mentioned offhand by others, taking a different approach from other [[AnimatedAdaptation Anime Adaptations]] of popular works like ''Anime/TheIdolmaster'' and ''Anime/SuperSonico'', where The Producer and The Manager were given features and sufficient characterization.
* In the anime adaption of ''[[VideoGame/DisgaeaHourOfDarkness Disgaea]]'', Big Sis Prinny is left out, which is important as [[spoiler:she's Laharl's mother and her death is the reason he's so bitter towards Love]].
* A few ''Franchise/{{Pokemon}}'' characters never appeared in the [[Anime/{{Pokemon}} anime]]. With [[MisplacedRetribution Pikachu's actions]] in the Porygon episode causing a seizure incident, its evolutions will never appear in anything bigger than a cameo in any anime episode. Quite a number of human characters do not appear as well, including Gym Leader Janine, some of Generation IV Frontier Brains, Blue's sister Daisy, and several Elite Four members.
** Team Plasma was also thought to be this for a while, after their first appearance was cancelled after the [[TooSoon Tohoku Earthquake]]. But the depiction of the team from ''VideoGame/PokemonBlack2AndWhite2'' ended up appearing as [[ArcVillain Arc Villains]] after the Unova League tournament.
** Pokemon protagonists often pop up in cameos but Leaf, the female protagonist for the Kanto remakes, has yet to appear. None of the Unova protagonists have popped up either.
** Some of the rival characters went through this. The rival from ''Gold and Silver'' was adapted into Paul, but Brendan only gets a brief cameo and Wally, Hugh, and Calem don't even get that much.
* Though his minions and many elements of ''Videogame/SuperMarioBros2'' appear in {{Animated Adaptation}}s of the ''Franchise/SuperMarioBros'' series, Wart has yet to appear in any of them, Bowser/King Koopa usually acting as a CompositeCharacter for them both. He did make the odd appearance in the comics however.
** Tatanga was conspicuously absent from the comic adaptation of ''VideoGame/SuperMarioLand2SixGoldenCoins''.
* In the ''VisualNovel/{{Clannad}}'' VisualNovel, Kappei was actually an important (if late introduced) character with his own ending and everything, but so far has not appeared in any ''Clannad'' anime adaptation ever.
* When ''Popotan'' got its adaptation, some characters disappeared completely. One of them was the main character.
* Knuckles, Metal Sonic and Amy were skipped by ''WesternAnimation/SonicSatAM'' as a result of the show's [[SpotlightStealingSquad focus on its original characters]]. In fact, only three of its characters came from the games.
** Tails and Amy Rose are not in ''WesternAnimation/SonicUnderground''. In fact, Amy wasn't in ''any'' animated ''Sonic'' material until ''Anime/SonicX'', [[OlderThanTheyThink which led many detractors to believe she was created for that show]].[[labelnote:†]] Amy's creation predates that of every other character in the franchise aside from Eggman/Robotnik and Sonic himself. Yes, she even predates ''Tails'' – despite her introductory game ''VideoGame/SonicCD'' coming out several months after ''[[VideoGame/SonicTheHedgehog2 Sonic 2]]'', it actually started development earlier (which is why the game has an EasterEgg of Tails saying "See You Next Game").[[/labelnote]]
* The live-action film adaptation of ''Film/PhoenixWrightAceAttorney'' had to drop nearly all of the third case and a good chunk of the second, so quite a few characters were cut. Most notable were April May (whose role was taken over by [[CompositeCharacter Redd White]]), Cody Hackins, Wendy Oldbag, Jack Hammer, and Will Powers. Every character introduced in the fifth case, "Rise from the Ashes", is also missing. However, given that that case wasn't in the original GBA game, instead being added to the UpdatedRerelease for the DS as an epilogue of sorts, that's kind of understandable.
* ''VideoGame/{{Wing Commander}}'s'' PlayerCharacter, Christopher Blair, is all but written out of most of the ''Literature/WingCommander'' novels, save for ''Heart of the Tiger'' and ''The Price of Freedom'', both novelizations of the games. The books instead tend to focus on the exploits of either Admiral Tolwyn or [[BreakOutCharacter Jason Bondarevsky]], [[HeroOfAnotherStory or a number of Blair's wingmen from the games.]]
* ''VideoGame/MetroidPrimePinball'': Of the five main bosses from ''VideoGame/MetroidPrime'', Flaahgra is the only one to make no appearance.
* The [[Manga/KingdomHeartsI manga adaptation]] of ''VideoGame/KingdomHearts'' left out Deep Jungle, the ''Disney/{{Tarzan}}'' world, due to rights issues. Also, subsequent games have acted like [[CanonDiscontinuity the world never existed]], leaving a minor plot hole.
** Of the still-legitimate worlds in the series, [[WesternAnimation/TheNightmareBeforeChristmas Halloween Town]] was also adapted out despite its massive popularity. ''Manga/KingdomHeartsII'' also excludes [[Disney/TheLittleMermaid Atlantica]], [[Franchise/PiratesOfTheCaribbean Port Royal]] and the [[Disney/TheLionKing Pride Lands]], while ''Manga/KingdomHearts358DaysOver2'' excludes, in a bit of irony, [[Disney/{{Hercules}} Olympus]] [[RecurringLocation Coliseum]].
* In two manga adaptations of the [[FireEmblemJugdral Fire Emblem: Genealogy of the Holy War]] games, different characters hqave been cut out:
** Mitsuki Oosawa manga: Holyn and Beowulf, prospect love interests for Ayra and Raquesis, disappear from the story -- while Ayra [[BelligerentSexualTension hooks up with Lex]] and [[LadyAndKnight Raquesis with Finn.]] (after having her BrotherSisterIncest deal with Eldigan cranked UpToEleven [[spoiler: until he dies]]) This was presumably done to avert DerailingLoveInterests - [[FridgeLogic which doesn't explain]] why Oosawa kept an expy of Eldigan's canon wife Grahnye around [[DieforOurShip and made her a total asshole]], while still capable of making a LoveTriangle between Ferry, Lewyn and Sylvia without derailing the loser (Sylvia, who instead is very sympathetic).
** Nea Fuyuki manga: Sylvia's children Leen and Corple. (And in the meantime, [[spoiler: Leen's love interest Ares has his eyes set on Princess Julia instead]]). Fuyuki allegedly said in author's notes that she ''wanted'' to keep them around, but time restrains didn't allow her to.
* The first ''Franchise/BreathOfFire'' manga, which adapted [[VideoGame/BreathOfFireI the first game]], omitted the QuirkyMinibossSquad almost entirely (only 1 out of its 4 members appears) despite being the main enemies for a fourth of the game.
** The AudioAdaptation of ''VideoGame/BreathOfFireIII'' drops entire arcs out of the Childhood Chapter, which led to characters such as Rei, Teepo, Palet and the entire TournamentArc not featuring in there.
* In the ''Franchise/MassEffect'' ExpandedUniverse, it's fairly common for Commander Shepard to be entirely absent, due to very customizable nature of the character (in terms of gender, ethnicity, background, and major plot decisions). The writers tend to take it as an opportunity to [[WorldBuilding flesh out the wider universe instead]].

[[folder: Adapted from Web Original]]
* In the original ''Series/{{Noob}}'' webseries, an EvilAllAlong character was introduced under the context's equivalent of a fake identity that lasted a few episodes. The novel and comic first show the character under her real identity. The fake one is mentionned in the novel, but seemingly completely disappeared in the comic [[SubvertedTrope before briefly showing up in a comic-only subplot]].

[[folder: Adapted from Western Animation]]
* When ''WesternAnimation/FluppyDogs'' was adapted into an hour-long Television Movie, there was a sixth Fluppy named Fanci who did not appear in the film at all.
* The [[Film/TheLastAirbender film adaptation]] of ''WesternAnimation/AvatarTheLastAirbender'' ommited Suki, The Warriors of Kyoshi, Jet, and King Bumi.
* The [[Film/InspectorGadget live-action film adaptation]] of ''WesternAnimation/InspectorGadget'' by Creator/{{Disney}}, aside from other notable changes made to the source material, completely omits Dr. Claw's international crime organization M.A.D., instead having him assisted by a goon named Sykes and a MadScientist named Kramer. The sequel also avoids using M.A.D., instead having Claw assisted by a pair of crooks names Brick and [=McKibble=] and later hiring three criminals known as Squint, Jungle Bob, and the Ninja, though ironically the latter two were M.A.D. agents in the original cartoon.
