7In a work of fiction, there are two characters who aren't related in any way. The creator may not have intended for them to be related (at least, not at the time, anyway). But when that work is adapted to another form of media, suddenly the people in charge decided to make them relatives. This can be for a variety of reasons including (but not limited to):
8
9* A [[PragmaticAdaptation pragmatic change]] to eliminate some exposition; it's easier to introduce Alice and Bob as siblings than to introduce Bob as Alice's LikeBrotherAndSister childhood friend [[StayingWithFriends staying at her house]] while his parents are dead, missing, or off being the HeroOfAnotherStory.
10* The characters have something that makes them very similar (be it superpowers, appearance, motivations, what have you), and thus linking them together makes sense thematically.
11* By making the characters relatives the stakes are raised and there's a more personal connection between them than if they were just friends.
12* Avoiding the UnfortunateImplications of an adult being OneOfTheKids by making said adult a (grand)parent, uncle/aunt or an elder sibling to at least one of the kids they're running around with.
13* Trying to [[HideYourLesbians stomp out homosexual undertones]] in the original work by making the affection characters share familial instead.
14* Adding a twist to a remake of a story that is subject to ItWasHisSled.
15* The result of creating a CompositeCharacter or being NamedByTheAdaptation.
16
17May result in an AdaptationNameChange, particularly surnames. When it's specifically love interests being turned into family members in the transition, the casting equivalent would be CastIncest.

33[[folder:Anime & Manga]]
34* In the ''Franchise/AceAttorney'' games, Celeste was Adrian's mentor; in the [[Anime/AceAttorney2016 anime adaption]], they're sisters instead.
35* The ''Anime/AmadaAnimeSeriesSuperMarioBros'' version of ''Momotaro'' turns Mario and Peach into siblings. It's not mentioned directly in the narrative but the two were [[RaisedByGrandparents raised by the same couple]], thus making them related. The short ends on a platonic note, avoiding any [[NotBloodSiblings incestuous undertones]].
36* ''Anime/ArabianNightsAdventuresOfSinbad'': Due to the series being an AdaptationAmalgamation of various stories from ''Literature/ArabianNights'', this happens with [[EvilWizard evil wizards]] Satajit (who was adapted from "Aladdin") and Balba (who was adapted from "The Enchanted Horse"). While in the original story collection these are two standalone stories, and the two wizards are thus unrelated, the anime turns them into brothers, and they frequently team up against Sinbad.
37* The 80s and 2000s adaptations of ''Manga/AstroBoy'' made Atlas, a minor antagonist from the manga, into Astro's "brother."[[note]]The 80s version of Atlas was created from the stolen blueprints that had previously been used to build Astro, while in the 2003 version, he was built by Astro's creator Dr. Tenma.[[/note]]
38* In the Italian dub of ''Anime/AttackerYou'', it’s mentioned You is a cousin of Kozue, the protagonist of ''Manga/AttackNumberOne'' (an earlier volleyball anime that was successful in Italy), even if the two series are completely unrelated.
39* The 2004 ''Manga/BlackJack'' anime features appearances from ''Manga/TheThreeEyedOne'''s Hosuke Sharaku and Chiyoko Wato, but with Chiyoko as Hosuke's older sister rather than his classmate and love interest.
40* When Creator/{{Nelvana}} {{Macekre}}d ''Anime/CardcaptorSakura'' into ''Cardcaptors'', they made two of Sakura's classmates who were clearly fond of each other, with a snarky, cute relationship, into cousins. Then they removed the fact that [[ChildhoodMarriagePromise Meiling]] and Syaoran were cousins by changing Meiling's surname to Rae.
41* ''Manga/{{Chobits}}'': The anime made Yumi Omura the daughter of the owner of the pub where she worked. They weren't related in the manga, where she was just another employee.
42* ''Anime/DigimonAdventure'': Originally, the [=DigiDestined=] hitchhiked with a total stranger. The American dub, with its [[TooSmartForStrangers concerns about stranger danger]], made it so that he's Sora's cousin, thus giving a reasonable explanation why the kids would trust him.
43* The 2007 remake of ''Anime/DoraemonNobitasGreatAdventureIntoTheUnderworld'' adds a subplot absent in the 1985 movie or original manga, where Demaon's [[TheDragon dragon]], Medusa, is actually the mother of Miyoko who sold her soul for a DealWithTheDevil in order to save an infant Miyoko in the past, getting transformed into a Gorgon-like demon in the process.
44* In the ''VideoGame/FZero'' game continuity, Captain Falcon and Jody Summer aren't directly related; one unlockable video in ''VideoGame/FZeroGX'' hints that the two may have been or currently are dating. In the anime ''Anime/FZeroGPLegend'' however, [[spoiler:Jody and Falcon are siblings since in this universe Captain Falcon's identity is Andy Summer]].
45* Several of the Homunculi in the first ''Anime/FullMetalAlchemist2003'' anime are reimagined as "[[CameBackWrong undead]]" family members of several main characters from [[Manga/FullMetalAlchemist the source material]]:
46** Sloth turns out to be [[spoiler:the Elric brothers' mother]].
47** Envy is revealed to be [[spoiler:Hohenheim's first son from long ago, making him the Elrics' half-brother]].
48** Lust is revealed to be [[spoiler:Scar's sister-in-law]].
49** Its version of Wrath is revealed to be [[spoiler:Izumi Curtis' "resurrected" unborn child]].
50* ''Manga/KaguyaSamaLoveIsWar'', which is a modern-day retelling of ''The Tale of the Bamboo Cutter'', has it where Kaguya is related to the emperor's counterpart (who was her love interest in the original story). More specifically, [[spoiler:he's Mikado Shijo, the twin brother of her cousin Maki]].
51* In one of the [[Manga/TheLegendOfZeldaI manga adaptations]] of ''VideoGame/TheLegendOfZeldaI'', Link and Zelda are half-siblings. Link doesn't realize this and [[SurpriseIncest has a crush on Zelda]], but she only likes him in a familial way. Link is half-elf and an illegitimate child from an earlier romance Zelda's deceased mother had, so he was raised separately from Zelda and does not know of his royal heritage.
52* ''Franchise/LyricalNanoha'':
53** ''Manga/MagicalGirlLyricalNanohaINNOCENT'':
54*** ''[=INNOCENT=]'' made Linith and Teana (two characters whose only connection in the original continuity is a MasterApprenticeChain, and they aren't even the same species) into sisters. The same is done with Jail and Quint, which makes their children all cousins. [[spoiler:Somewhat downplayed as the Numbers were all sisters, but not biologically related.]]
55*** Downplayed with the six Nakajima sisters, who were all adopted in the original continuity but were changed to be the biological children of Genya and Quint. [[spoiler:Even more downplayed with Ginga, Subaru, and Nove who were originally Quint's clones.]]
56*** Also downplayed with Uno, Due, Tre, Quattro and Sette who were still Jail's children in the original continuity, but were changed to all be his biological children. Even more downplayed with Uno, who's a female clone of Jail.
57*** Played for laughs when it's jokingly suggested that Sacred Heart is a descendant of Vita's stuffed rabbit.
58*** Vivio is implied to be Nanoha and Fate's [[HomosexualReproduction biological daughter]] instead of being adopted.
59*** Inverted and downplayed regarding Fate. She was never adopted into the Harlaown family in the ''INNOCENT'' continuity since Precia is both alive and sane, but the family bond still exists due to Precia and Lindy being HeterosexualLifePartners who are raising their kids side-by-side.
60** Downplayed with the Takamachi siblings. In ''VisualNovel/TriangleHeart3SweetSongsForever'', Nanoha and Kyouya are half-siblings and Miyuki is their first cousin. In ''Lyrical Nanoha'' proper, there's nothing to suggest that they're not all full-blooded siblings (other than the fact that it would mean that Momoko [[AbsurdlyYouthfulMother gave birth to Kyouya at 14]]).
61* ''Anime/MobileSuitZetaGundam'': In "A New Translation," Stephanie Luio is introduced as Wong Lee's daughter, whereas the original series they weren't related and she was instead his DistaffCounterpart. This would only be canon for the New Translation movies as ''Anime/MobileSuitGundamNarrative'' would introduce her father, Woomin Luio.
62* The ''Manga/MyHime'' manga made Natsuki an older sister to [[spoiler:Alyssa]], when their [[Anime/MyHime anime counterparts]] weren't related.
63* ''Anime/PokemonTheSeries'': Inverted when Professors Kukui and Burnet are colleagues instead of being married like in the games. [[spoiler:This is subverted at the conclusion of the Nebby arc when they get married.]]
64* The ''Anime/SailorMoon'' Cloverway English dub rather infamously made Sailors Uranus and Neptune cousins as something of a lazy fix to cover up the [[HideYourLesbians flirting between the two so it was appropriate for a '90s American kids' show]]. Unfortunately for the {{Moral Guardian}}s, the change not only still made them come across as lesbians, but also ''[[KissingCousins incestuous lesbians]]''. [[SarcasmMode Which was so much better]] [[DubText than just being lesbians]]. What was really ironic was that the change could've worked had Cloverway bothered to edit out any of the flirting between the two. Instead, the scenes were kept and characters repeatedly referred to them as cousins, even when they were villains who would logically have no way of knowing of their civilian identities.[[note]]For instance, Kaolinite captures Neptune in one episode and tells Uranus "Surrender, or this is the end of the road for your cousin here," while in the original Japanese version, she simply calls Neptune "Your friend."[[/note]] It wasn't so much the change itself that's infamous as much as how poorly it was done. It just made the fact that they were trying to hide what was really a lesbian relationship that much more obvious.
65** Pulled again by Cloverway in a fourth season episode. Two one-shot characters were made brothers when they weren't related in the Japanese dub. Due to this the fandom suspects they were supposed to be a gay couple and this was the dubbers' way of hiding that. The fact that one of these characters was targeted by an undisguised [[CampGay Fisheye]] and the other one appears [[GreenEyedMonster to have gotten jealous]] when Fisheye hit on him seems to support this notion. Also the fact that the VictimOfTheWeek had a job stereotypically held by gay men: fashion designer.
66** The Polish dub turned Kunzite and Zoisite into brothers to hide that they were [[MasculineFeminineGayCouple very obviously a gay couple]] in the Japanese dub. Seems to have worked, though Zoisite was such a gay stereotype so obsessed with Kunzite that there was only so much the dubbers could do and sometimes the original romantic intentions slipped through, making it seem like [[BrotherSisterIncest dub!Zoisite was in love with his brother]]. Ironically this change was closer to what their relationship was in the manga; [[AdaptationalSexuality they're a gay couple only in the anime]].
67* This trope is averted hard in all the anime adaptations of ''Manga/SaintSeiya''. In the manga, is eventually revealed the five main characters are [[spoiler: half brothers, and their father is Mitsumasa Kido]]. All the anime versions and spin offs omit this information, leaving the main characters as friends, with only two of them being brothers.
68* The manga ''Sensha Otoko: A True Tank Story'' is an AU of the ''Franchise/FateSeries'' with no supernatural elements. Waver Velvet (who is {{Gender Flip}}ped into a girl) and Diarmuid are siblings and the children of Kayneth and Sola-Ui.
69* In a bit of CanonWelding, the TwistEnding of the 2007 ''Manga/SkullMan'' anime reveals that the main character is actually the father of the title character from ''Manga/{{Cyborg 009}}''.
70* In the 70s manga adaptation of ''[[Manga/SpiderManTheManga Spider-Man]]'', Spidey's primary love interest in the early chapters is a teenage girl named Rumiko "Rumi" Shiraishi. While it's debatable as to whether she's a closer analogue of ComicBook/MaryJaneWatson or Gwen Stacy, Rumi turns out to be Electro's little sister, something that isn't true of either girl in the American version.
71* An odd case in the manga adaption of ''Anime/YuGiOhArcV'': [[spoiler: Yuya came from the future in this continuity, with the other three Yu boys already being in his mind at the start. In the end, Yuzu marries Yusho, and [[KidFromTheFuture all four are her sons]]. They never acknowledged her as their mother during the entire series.]]

75* Sam Simeon of ''ComicBook/AngelAndTheApe'' being related to Grodd was added in the post-Crisis Creator/PhilFoglio book; in UsefulNotes/TheSilverAgeOfComicBooks, he was just a talking gorilla with no explanation whatsoever. Then inverted in the ComicBook/New52, where ''ComicBook/ForeverEvil2013'' introduces Sam (also known as Primeape) as having no relation to Grodd and [[AdaptationSpeciesChange not even a gorilla]], but a human who suffered an accident with enhanced gorilla DNA.
76* ''ComicBook/Batman66'', the comic book continuation of the ''Series/Batman1966'' TV show, has several instances of making characters who originally had no connection to one another related.
77** The Clock King is revealed to be Morris Tetch, brother of the Mad Hatter/Jervis Tetch. This relationship was not alluded to in the show and does not come from the comics, where the Clock King is William Tockman.
78** The one-shot crossing over with ''ComicBook/LegionOfSuperHeroes'' establishes that the villain Egghead is the ancestor of the Legion's enemy Universo.
79** The ''ComicBook/ArchieComics'' crossover reveals through dialogue that Robin and Betty Cooper are second cousins once removed through Robin's Aunt Harriet.
80* ''ComicBook/BatmanLobo'' establishes that Batman and the Joker are twin brothers, with the Joker's real name being given as Joey Wayne and turning to a life of crime because Joe Chill kidnapped him the night his and Bruce's parents were shot.
81* Following the 2010s SoftReboot of ''ComicBook/TheBeano'', the [[AllThereInTheManual website and character guide]] say that ComicStrip/DennisTheMenaceUK's mother Sandra is the sister of Minnie the Minx's mother Vicky, making Dennis and Minnie cousins. They was no prior indication of this, and until the reboot there was a mild ShipTease. (And since fans never let go of a ship, {{Fanon}} now has it that, since 2010s Dennis's Dad is more-or-less confirmed to be 1980s Dennis, Sandra is in fact the previous version of Minnie.)
82* ''ComicBook/DCComicsBombshells'':
83** ComicBook/{{Stargirl}}'s family was the one who found Supergirl's rocket when she was sent to Earth as a baby. Stargirl was also an infant at the time, so they were raised together as sisters.
84** Killer Frost, ComicBook/{{Zatanna}}, and ComicBook/{{Raven}} are the adopted daughters of the Joker's Daughter.
85* ''DC: Earth One'':
86** In ''ComicBook/SupermanEarthOne'', General Zod is Jor-El's brother and hence Superman's uncle.
87** ''ComicBook/TeenTitansEarthOne'': Both subverted and inverted with Rita Farr [[AdaptationNameChange (renamed Rita Markov)]] who is now Tara Markov’s mother [[spoiler:although they're still not biologically related]], but is no longer Garfield Logan’s adopted mother or married to Steve Dayton.
88** In ''ComicBook/WonderWomanEarthOne'', [[spoiler:it's revealed that Wonder Woman is the daughter of Hercules, who raped her mother Hippolyta.]]
89* DC's adaptation of ''Film/DemolitionMan'' was an EarlyDraftTieIn where one of the sewer refugees is Spartan's daughter.
90* In the European ''ComicBook/DisneyDucksComicUniverse'' comics, it was for the longest time assumed that Uncle Scrooge and Grandma Duck were brother and sister, what with her [[MoralityPet being one of the few people that Scrooge respects and act kindly towards]] and her refusing to let him put on airs around her--the idea being that he left the farm to make his fortune and she stayed and used the same grit to be a farmer and home-maker. When ''ComicBook/TheLifeAndTimesOfScroogeMcDuck'' explained their actual relation, that Grandma's son Quackmore married Scrooges youngest sister Hortense (who is about fifteen years younger than Scrooge, explaining the generational gap) and became the parents of Donald Duck, it actually drew headlines.
91* Princess Petra/Spinstress from ''ComicBook/EdgeOfSpiderVerse2022'' is the daughter of Queen Mysteria, her world's version of Mysterio.
92* In ''ComicBook/{{Fables}}'', this happens a lot, in part due to use of CompositeCharacter
93** Snow White becomes the sister of [[Literature/SnowWhiteAndRoseRed Rose Red]]. They hadn't even met in their original stories and Rose's Snow White was a different (and [[AdaptationDyeJob blonde]]) sibling, but they managed to compensate for this by [[CompositeCharacter combining the two Snows]] into one.
94** Jack Frost turns out to be son of the Ice Queen and Jack Horner, who himself is every single other Jack from fairy tales and nursery rhymes (except Jack Sprat).
95** Prince Charming is ex husband of Snow White, Sleeping Beauty ''and'' Cindirella and father of abovementioned Jack Horner.
96** Bigby, better known as the Big Bad Wolf, is son of North Wind, explaining where his power to huff and puff comes from.
97* ''ComicBook/GIJoeReloaded'' makes it so that Snake Eyes and Storm Shadow are half-brothers.
98* Creator/IDWPublishing's ''ComicBook/{{Gobots}}'' miniseries ends with [[CanonWelding strong implications that the GoBots are actually precursors to the]] Franchise/{{Transformers}}, one example being that it is hinted that Road Ranger and Bug Bite are the respective fathers of the Autobots Optimus Prime and Bumblebee.
99* In ''ComicBook/GothamCityGarage'', James and [[ComicBook/{{Batgirl}} Barbara Gordon]] are [[ComicBook/{{Supergirl}} Kara Zor-El]]'s adoptive family. For years, Kara and Barbara thought they were biological sisters.
100* ''ComicBook/HeroesReborn''[='=]s Rikki Barnes's paternal grandparents are implied to be ComicBook/BuckyBarnes and ComicBook/PeggyCarter.
101* ''ComicBook/HannaBarberaBeyond'': In the 2017 ComicBookAdaptation of ''WesternAnimation/TheJetsons'', the Jetsons' RobotMaid Rosie is retconned into George Jetson's mother living with her mind in a robot body.
102* An unusual example in that it wasn't actually an adaptation, just a strip with NoContinuity--when the UK AnthologyComic ''Hoot!'' was [[ComicsMerger merged]] with ''ComicBook/TheDandy'', ''Hoot''[='=]s strip about a troublemaking baby, ''Cuddles'' was combined with ''The Dandy''[='=]s similar strip, ''Dimples''. The first ''Cuddles and Dimples'' strip showed Cuddles' family moving next door to Dimples' and the two babies becoming friends. At some point over the next year, Cuddles' parents stopped appearing and the babies were portrayed as twin brothers.
103* In the ''ComicBook/InjusticeGodsAmongUs'' comics, Connor Hawke's mother is ComicBook/BlackCanary rather than Sandra "Moonday" Hawke. This entails Connor's surname being changed to Lance-Queen.
104* In the ''WesternAnimation/{{Jem}}'' cartoon, Aja and Shana became Kimber's and Jerrica's foster sisters at a young age, but are treated more like close friends. In the [[ComicBook/JemAndTheHologramsIDW IDW comics]], they make it a point to [[HappilyAdopted show that they are all sisters.]]
105* In the 39th issue of the ''ComicBook/JusticeLeagueUnlimited'' tie-in comic, Detective Chimp mentions that he has a cousin named Sam who is a cartoonist, implying that he's related to this continuity's [[ComicBook/AngelAndTheApe Sam Simeon]].
106* In ''ComicBook/LegionOfSuperHeroes2020'', Mon-El's a distant descendant of Superman and ComicBook/{{Superboy}}. He never had any familial ties to Superman in any previous continuity, though the pre-Zero Hour and Retroboot continuities established him to have met Superman during his days as the original Superboy and being mistaken for Clark's older Kryptonian brother before exposure to lead caused him to regain his initially lost memories.
107* The Marvel Comics hero Mercury was originally stated to be the son of Zeus and cousin of Pluto, in a clear case of either SadlyMythtaken or just not caring about accuracy. He was soon retooled as "Hurricane", still a god, but now the son of ''Thor'' and still cousin of Pluto. That was all tossed aside when both were retconned into being the ''ComicBook/{{Eternal|s}} Makkari, and Pluto was retconned into being Warlord Kro, deviant enemy of the Eternals, in disguise, making them now an example of UnrelatedInTheAdaptation.
108* In ''ComicBook/MegaManArchieComics'' series, Ra Moon from ''VideoGame/SuperAdventureRockman'' is the creator of [[VideoGame/MegaMan3 Shadow Man]], [[VideoGame/MegaManV the Stardroids, and Sunstar]], as well as the master of the evil robot Duo fought at the start of ''VideoGame/MegaMan8''. In the original games, absolutely none of these alien robots were said or implied to be connected to one another (not even in [[AllThereInTheManual the manuals]]).
109* ''ComicBook/TheMightyThor'': This series has a habit of completely screwing with the gods' relationships to each other as compared to the [[Myth/NorseMythology source material]]. Even more shocking since not many characters from the myths actually make it into the comic.
110** Sif and Heimdall are siblings in the comic, but have no relation to each other in mythology. The only relatives of the latter that are mentioned are nine mothers and of the former are her son and husband.
111** May have happened to Thor and Tyr, but [[DependingOnTheWriter mythology's not clear on their relationship]] to begin with. In the comic, they're explicitly brothers. One version of Tyr's genealogy has Odin as his dad, which would make him Thor's half-brother, so the comic wouldn't really have changed their relationship. Another version of his parentage gives a completely different figure as his dad, making them unrelated in myth, but related in the comic adaptation.
112* ''ComicBook/MuppetClassics'' had two miniseries where the story was spiced up by making characters who weren't family in the original story relatives in the adaptation.
113** ''[[Myth/RobinHood Muppet Robin Hood]]'' establishes that Maid Marian is Prince John's niece.
114** ''[[Literature/SherlockHolmes Muppet Sherlock Holmes]]'' had the twist of Irene Adler (portrayed by Miss Piggy) turning out to be the adopted sister of Professor Moriarty (portrayed by Uncle Deadly).
115* ''The ComicBook/New52'':
116** ComicBook/WonderWoman is now the daughter of Zeus and aunt of ComicBook/WonderGirl (Cassie). Diana was already Zeus' great-granddaughter and had previously been Cassie's grand-niece but writers often ignored this as it would require them to draw attention to Ares' being Diana's grandfather. Nothing in the New 52 hints Ares is no longer Hippolyta's father meaning this version of Diana is the product of some serious RoyalInbreeding.
117** In the ''The Forever People'', Serafina (the {{Gender Flip}}ped version of Serifan from previous continuity) is Vykin the Black's sister. This also entails giving the blond Serifan a RaceLift.
118** In the Villains Month OriginsEpisode for ComicBook/{{Darkseid}}, he was the brother of Avia, and therefore the brother-in-law of Highfather. (Avia herself remains a PosthumousCharacter.)
119** In ''ComicBook/{{Shazam}}'' back-up strips in ''ComicBook/JusticeLeague'', Billy and his ''ComicBook/{{Flashpoint}}'' friends are now foster-siblings.
120** The New 52 version of Arthur Light (who is [[AdaptationalHeroism not a villain]]) is married to Kimiyo Hoshi, the heroic Dr Light II in the previous continuity.
121** ''ComicBook/Earth2'': Before the New 52, Fury was the daughter of Earth-2's Wonder Woman and ComicBook/SteveTrevor. She is still Wonder Woman's daughter, but she's born illegitimately after her mother was manipulated by Fury's father [[spoiler:Steppenwolf]].
122** In ''ComicBook/JusticeLeagueDark'' #19, it is revealed that Madame Xanadu is the mother of Dr Destiny. Pre-Flashpoint, his mother was established in ''ComicBook/TheSandman1989'' to be a woman named Ethel Cripps.
123** In the ''Superman/Wonder Woman'' tie-in to ''ComicBook/SupermanSavageDawn'', Angle Man is the son of ComicBook/VandalSavage.
124** The valkyrie Gundra, an obscure ComicBook/WonderWoman villain from Earth-2 continuity, is revealed to be the ancestor of a long line of Amazon-haters, whose name evolved over the centuries from "von Gundra" to "von Gunther". As in Paula von Gunther.
125* ComicBook/{{Shazam}}:
126** In the first Post-Crisis revamp, ''ComicBook/ShazamTheNewBeginning'', Captain Marvel's arch-nemesis Dr. Sivanna is his step-uncle (making him a CompositeCharacter with Billy's EvilUncle Ebeneezer) and Uncle Dudley is his ''real'' uncle (instead of [[HonoraryUncle an honorary one]]) named [[AdaptationNameChange Dudley Batson]]. Both were later {{Ret Con}}ned.
127** As a form of CanonWelding, DC Comics made Freddy Freeman (Captain Marvel Jr.) and Kid Eternity brothers after acquiring both characters from separate companies. They had remarkably similar origin stories (RaisedByGrandparents, grandpa died in a boating accident, they got a power that activates ByThePowerOfGreyskull and [[LightningCanDoAnything includes lightning]]), and since the Kid had NoNameGiven until then they could easily [[GivenNameReveal reveal]] he was Christopher "Kit" Freeman.
128** ''ComicBook/ThePowerOfShazam'' adds a couple of these to Mary's backstory. She was still raised by the Bromsfields, but Nora Bromsfield is now a cousin of Marilyn Batson. In addition, Sarah Primm was the sister of Theo Adam, Black Adam's present-day descendant and host body. In the Fawcett comics, Adam didn't need a host body and had no known connection to Primm. Combined with making Theo responsible for the Batsons' death, her backstory goes from "Nurse randomly gives orphaned baby to rich lady rather than tell her her child died" to "Nanny is worried about what her brother might do to orphan, so takes her to live with relatives". (And she'd have done the same for Billy if he hadn't dropped off the grid by then.)
129* If you consider ''ComicBook/SpiderHam'' to be an adaptation of ''ComicBook/SpiderMan'', then the ''Spider-Ham 2099'' story in ''What The-?!'' has Piguel O'Malley refer to Peter Porker as his ancestor. When Creator/PeterDavid created ''ComicBook/SpiderMan2099'', the first thing he decided was that Miguel O'Hara ''wasn't'' descended from Peter Parker.
130* ''ComicBook/SpiderManChapterOne'' makes ComicBook/NormanOsborn and Sandman cousins to explain their similar looking hair. Became this trope once the book was (very quickly) declared out-of-continuity and simply an alternate reality take on the Spidey mythos.
131* In ''ComicBook/StreetFighter'', Alex is descended from the same ancient bloodline as Gill and Urien. [[spoiler: This allows Gill's spirit to return and possess him in the finale of ''Street Fighter Unlimited''.]]
132* In the author's notes page for the first issue of the ''WesternAnimation/{{Superfriends}}'' [[RecursiveAdaptation comic book tie-in]], Creator/ENelsonBridwell reveals that he has decided (in lieu of early scripts naively trying to make her ComicBook/{{Batman}}'s niece) to make Wendy be Harvey Harris' niece, instead. Harvey Harris was a detective who helped young Bruce Wayne learn the ropes of the profession. He also speculates that the Wendy Harris who is ComicBook/{{Hourman}}'s wife on Earth-Two could be her counterpart (the two admittedly look similar). As for Marvin, he was the son of Daniel White and Diana White, the former Diana Prince, who let Wonder Woman assume her identity. All this was intended to explain just ''why'' the Superfriends would let these seemingly-random kids (and their dog) tag along with them on adventures. The former retcon was referenced in ''ComicBook/TheBatmanAndScoobyDooMysteries'', where Harris mentions his niece Wendy briefly.
133* ''ComicBook/SupermanAndBatmanGenerations'': Lois Lane is Supergirl's mother in this continuity, partly due to Supergirl [[RelatedDifferentlyInTheAdaptation being Superman's daughter instead of his cousin]].
134* ''ComicBook/TheSupermanMonster'', a DC Comics {{Elseworld}} consisting of a retelling of ''Literature/{{Frankenstein}}'' with Lex Luthor in the role of Victor Frankenstein and Superman as the monster he creates, has Lois Lane's equivalent Eloise Edge (the story's take on [[CompositeCharacter both Victor Frankenstein's fiancee Elizabeth Lavenza and the monster's bride]]) being the daughter of Morgan Edge's counterpart Burgomaster Edge.
135* In the ''ComicBook/{{Superman}}''/''Literature/{{Frankenstein}}'' {{Elseworld}} mashup ''The Superman-Monster'', the Lois Lane (and Elizabeth) counterpart is Eloise Edge, daughter of Burgomeister Morgan Edge. Lois and the WGBS boss aren't related in normal continuity (and, for that matter, Elizabeth isn't the daughter of the burgomeister, even in adaptations where the burgomeister is a significant character).
136* In ''ComicBook/SupermanRedSon'', Kal-L is the last descendant of Lex Luthor sent back through time, as it was Lex's progeny that ensured that the Earth would become Krypton in the future. Superman was fighting his great-something grandfather the whole time.
137* ''ComicBook/TeenageMutantNinjaTurtlesIDW'':
138** In previous incarnations Karai was either unrelated to the Shredder or related to him by adoption. Here she is his biological granddaughter, making this the first time they’ve been portrayed as blood-related.
139** Hun [[CompositeCharacter is Casey Jones’ father]], when ironically [[WesternAnimation/TeenageMutantNinjaTurtles2003 his original counterpart]] killed Casey’s father.
140** A variation with the Turtles and Splinter. While, like previous versions, Splinter isn’t biologically related to the turtles ''now'', they are the respective {{Reincarnation}}s of a ninja master and his sons, meaning they ''were'' biological relatives in a past life, when prior iterations had no such relation. One could say this technically makes them "spiritually" related.
141* IDW did this a lot in their 2005-2018 run of ''Franchise/TheTransformers'' comics. For example, Arcee and Galvatron were revealed to be siblings in ''ComicBook/TransformersRobotsInDisguise'', while Tracks and Needlenose were likewise in ''ComicBook/TransformersMoreThanMeetsTheEye''. How exactly familiar relationships work in a mechanical species that doesn't engage in sexual reproduction is not explained.
142* ''ComicBook/TransformersVsGIJoe'':
143** The Decepticons Shockwave and Soundwave have had no confirmed familial ties in any other continuity, but this continuity made the two brothers.
144** Most continuities had Serpentor be an ArtificialHuman cloned from various infamous historical figures by Dr. Mindbender. In this comic, he is the future son of Cobra Commander and the Baroness, which also makes him half-brothers with Cobra Commander's son Billy.
145* ''ComicBook/UltimateMarvel'':
146** ''ComicBook/UltimateSpiderMan''
147*** In the main Spider-Man comics the name ComicBook/SpiderWoman has been used by a number of ladies, all of whom have almost nothing do with Spider-Man other than having similar names and powers. In ''Ultimate Spider-Man'' Spider-Woman is Peter Parker's OppositeSexClone; in civilian life she goes by the name Jessica Drew, which happens to be the civilian name of the first Spider-Woman in the mainstream Marvel Universe. Additionally, Tarantula and the [[DecompositeCharacter original]] Scorpion are clones of Peter, too.
148*** In the Ultimate verse Liz Allan is made a CompositeCharacter and thus is not only the alter ego of [[WesternAnimation/SpiderManAndHisAmazingFriends Firestar]], [[spoiler:The Blob]] is now her biological father.
149*** ComicBook/{{Morbius}} is the brother of {{Dracula}}.
150** ''ComicBook/TheUltimates'':
151*** M'Baku the Man-Ape is ComicBook/BlackPanther's older brother.
152*** The ComicBook/RedSkull is the bastard ([[BastardBastard in both senses of the word]]) son of [[spoiler:ComicBook/CaptainAmerica and Gail Richards from the Creator/RepublicPictures serials]].
153*** As opposed to being ComicBook/TheMightyThor's step-brother, ComicBook/{{Loki}} is his half-brother, with Odin fathering both of them.
154*** Gail Richards from the Creator/RepublicPictures ''Captain America'' serials married ComicBook/BuckyBarnes.
155** In ''ComicBook/UltimateFantasticFour'':
156*** ComicBook/DoctorDoom is a descendant of {{Dracula}}. This in turn makes him a distant relative of Morbius.
157*** ComicBook/{{Thanos}} is the father of Ronan the Accuser.
158** While Comicbook/ProfessorX and Moira [=MacTaggert=] of the traditional Marvel Universe have had romantic feelings towards each other, they ended up marrying different people. In ''ComicBook/UltimateXMen'', they did get married and later divorced. This resulted in their respective spouses (Gabrielle Haller and Joseph [=MacTaggert=]) being {{adapted out}}, the sons they had being [[CompositeCharacter the same character]] and two cases AdaptationNameChange (Moira's maiden name in the classic universe was Kinross, "[=MacTaggert=]" being the result of a [[DomesticAbuse very bad]] [[ChildByRape marriage]] and Proteus being named David Xavier).
159* '' ComicBook/TheUnstoppableWasp'': Both inverted and played straight for Nadia Pym, as despite being based on [[ComicBook/MarvelComics2 the Red Queen]] and [[Franchise/MarvelCinematicUniverse Hope van Dyne]], [[ComicBook/TheWasp Janet van Dyne]] serves as a surrogate mother, but isn't her birth mother--that instead being [[ComicBook/AntMan Hank Pym]]'s first wife, Maria Trovaya.
160* ''ComicBook/XMen'': In the main universe, there's no sign that Bolivar Trask and Moira [=MacTaggert=] knew each other in person. In the ''ComicBook/AgeOfApocalypse'', they're married.
161* In the comics based on ''WesternAnimation/YoungJustice2010'', the storyline "Gorilla Warfare" reveals that Primat (a member of the Dreambound in Creator/KurtBusiek's ''ComicBook/Trinity2008'') is the mate of Grodd in this universe, possibly because she's the only named female Gorilla City resident in Franchise/TheDCU. Their son, Simeon, is presumably meant to be Sam Simeon from ''ComicBook/AngelAndTheApe'', who is Grodd's ''grand''son in the comics, but no known relation to Primat.

164[[folder:Fairy Tales]]
165* In Kaja Foglio's "Literature/TheCatOnTheDovrefell" [[https://www.girlgeniusonline.com/funextras/stories/dovrefjell.php webcomic adaptation]], the traveler is Halvor's niece.
166[[/folder]]
167
168[[folder:Films -- Animation]]
169* Franchise/DisneyAnimatedCanon:
170** ''WesternAnimation/{{Bambi}}'': Bambi's father is left vague in the books however it isn't implied to be the Great Old Prince Of The Forest (who is an elderly and seldom seen figure). The Disney adaptation [[CompositeCharacter combines]] Bambi's father with the Great Prince.
171** ''WesternAnimation/{{Frozen|2013}}'' is also loosely InspiredBy ''Literature/TheSnowQueen.'' In the original, Gerda and the Snow Queen are totally unrelated (indeed, the Queen is closer to TheFairFolk); here the Queen (Elsa) and Gerda's equivalent (Anna) are sisters, and their relationship is the main theme of the movie. Early on in development, the two were unrelated. This was changed so that the two could have a closer relationship, originally of the CainAndAbel sort but later of the [[AloofBigBrother distant siblings]] kind.
172** ''WesternAnimation/{{Hercules}}'': The title character is the legit son of Zeus and Hera instead of only Zeus's by a mortal woman.
173* In the film of ''[[WesternAnimation/HortonHearsAWho2008 Horton Hears a Who!]]'' [=JoJo=] is introduced early on as the Mayor of Whoville's oldest child and only son. In the book, [=JoJo=] only appears right at the end, which could easily be the first time he and the Mayor have ever met. See also ''{{Theatre/Seussical}}'' below.
174* ''WesternAnimation/TheLionKingIISimbasPride'':
175** In a few dubs , Kovu is Scar's son. In the original English version of the film, Kovu was originally planned to be Scar's son, but this was changed late in development and a few lines were mentioned clarifying they're not related.
176** In ''Theatre/RomeoAndJuliet'', Mercutio is a kinsman from Prince Escalus; he hangs out with Romeo because he's his friend. However, In TLKII his closest character counterpart, Nuka, is Kovu's (allegedly) half-brother.
177* ''WesternAnimation/MeetTheRobinsons'' was based on the Creator/WilliamJoyce book ''A Day With Wilbur Robinson,'' where the [[NamedByTheAdaptation unnamed]] protagonist meets his friend Wilbur's family. In the film, the protagonist, Lewis, meets Wilbur because [[spoiler:Wilbur is his KidFromTheFuture, a fact not revealed until the third act]].
178* ''WesternAnimation/ThePrinceOfEgypt'': In the ''Literature/BookOfExodus'', Rameses and Moses are commander and soldier. In ''The Prince Of Egypt'', they are CainAndAbel like brothers.
179* ''Literature/RudolphTheRedNosedReindeer'':
180** In the original booklet, Rudolph has parents, but they never make a physical appearance (although he's seen writing a letter to his parents before helping Santa), and they're not members of Santa's team. In the [[WesternAnimation/RudolphTheRedNosedReindeer Rankin/Bass]] special he is Donner's son, while in ''[[WesternAnimation/RudolphTheRedNosedReindeer1998 Rudolph The Red Nosed Reindeer: The Movie]]'' he is Blitzen's son.
181** Comet, Cupid, Dasher, and Blitzen are brothers in ''Rudolph The Red Nosed Reindeer: The Movie''. No such relationship is implied in ''Literature/TwasTheNightBeforeChristmas''.
182* In the original ''Literature/TheSnowQueen'', Gerda and Kai are very close friends and [[ImpliedLoveInterest implied love interests]] who grew up together. In the [[Animation/TheSnowQueen2012 2012 adaptation]], they're biological siblings who were separated until right before Kai gets kidnapped.
183* ''Animation/SonOfTheWhiteHorse'' flips almost every relationship on its head:
184** In the folk tales, Treeshaker, Stonecrumbler and Irontemperer are unrelated, while in the film they're the White Mare goddess' three sons. In most versions of the original story, the White Mare's Son is a separate character from all three.
185** The king, the mysterious old man from the forest and the evil goblin are also originally unrelated characters, but the movie not only reimagined them [[CompositeCharacter as different forms of the same deity]], it also made him the three brothers' missing father and the White Mare's "husband".
186** Oddly, the three princesses who become the brothers' wives ''still'' call the king their father like in the original tales. The movie made this relation metaphorical rather than biological to avoid UnfortunateImplications. The princesses were merely created by the king's magic to be his actual sons' brides.
187* Because Otter is AdaptedOut of ''WesternAnimation/TheWindInTheWillows1985'', but it ''does'' include "Piper at the Gates of Dawn", which features his son Portly, the film makes Portly Badger's nephew instead.
188[[/folder]]
189
190[[folder:Films -- Live-Action]]
191* In the Creator/BarryHumphries vehicle ''The Adventures of Barry [=McKenzie=]'', [=McKenzie=], from Humphries' comic strip in ''Magazine/PrivateEye'', is revealed to be the nephew of his stand-up character Mrs. Edna Everage. The films are apparently canon for Edna because she gets [[UsefulNotes/KnightFever a damehood]] at the end of the sequel and has been Dame Edna ever since.
192* The ''Film/AlvinAndTheChipmunks'' films has Dave adopt the Chipettes, which makes them and the boys all adopted siblings. It however ''didn't'' change the ShipTease between the girls and the boys. They're NotBloodSiblings but it's jarring to see BrotherSisterIncest in the franchise.
193* ''Film/{{Barbarella}}'': For the film, CreepyTwins Stomoxys and Glossina were made into the nieces of the Black Queen, while in the comics they had nothing to do with each other and appeared in different stories. They're still not shown interacting in the film.
194* In ''Film/BatmanAndRobin'', ComicBook/{{Batgirl}} is made Alfred's niece (instead of being Commissioner Gordon's daughter).
195* In ''Film/BlackAdam2022'', Ahk-Ton is the ancient ancestor of Sabbac.
196* In ''Film/{{Casper}}'', the Trio become Casper's uncles.
197* In ''Film/CountDracula1977'', the BBC version of ''Dracula'', Mina and Lucy are sisters whereas in the original novel they were childhood friends.
198* In the original book of ''Literature/TheDevilsArithmetic'', Rivka and Chaya are girls from two different villages who end up in the same concentration camp. In the film adaptation, they're cousins.
199* The ''Series/DoctorWho'' film ''Film/DrWhoAndTheDaleks'' had Susan ''and'' Barbara as Dr. Who's granddaughters (with the surname "Who" no less), with Ian being Barbara's boyfriend.
200* ''Film/{{Dracula 1979}}'' makes Lucy the daughter of Dr. Seward and Mina the daughter of Professor Van Helsing.
201* The ''[[Film/GIJoeTheRiseOfCobra G. I. Joe]]'' [[Film/GIJoeRetaliation Film Series]] sees [[spoiler:Cobra Commander and Baroness being made into siblings in the movies. In the comics, Baroness's brother was an unrelated character who was killed off]].
202* In Creator/JosephConrad's ''Literature/HeartOfDarkness'', Marlow and Kurtz are strangers to one another. In [[Film/HeartOfDarkness1958 the 1958 television adaptation]], Marlow is Kurtz's protégé and adopted son.
203* Kirsty in ''Film/{{Hellraiser}}'' was originally a neighborhood love interest for Larry/Rory Cotton in the novella ''Literature/TheHellboundHeart''. In the movie she becomes his daughter.
204* In the 1968 TV-movie of ''Literature/{{Heidi}}'', Herr Sessemann is Heidi's uncle and Klara is her cousin. This change was probably inspired by ''Literature/TheSecretGarden'', the ''other'' famous children's novel about a young orphaned heroine who helps a wheelchair-bound LonelyRichKid [[ThrowingOffTheDisability Throw Off the Disability]]. Heidi's Aunt Dete, her MissingMom's sister, also becomes the Grandfather's estranged daughter instead of being unrelated to him, as in this version he's [[RelatedDifferentlyInTheAdaptation Heidi's maternal grandfather instead of paternal.]]
205* ''Film/HorrorOfDracula'': Arthur and Lucy are revealed as siblings in this one whereas in the original Arthur was her fiancee. (This also ends ups swapping their spouses. Arther is with Mina in this one and Harker [[spoiler: before being turned and staked by Van Helsing]] is Lucy's fiancee.)
206* ''Film/JemAndTheHolograms2015'':
207** Ms. Bailey is Jerrica's aunt instead of a woman that helps with the Starlight Girls.
208** Rio is [[spoiler:Erica Raymond's, a gender-flipped version of Eric,]] son. In the cartoon, there was only a few years difference between them.
209* It's played with a bit in ''Film/Joker2019''. Arthur Fleck suspects that his biological father may be Thomas Wayne, which would then indicate that him and Bruce Wayne are brothers this time around. However, it's never clarified if it's the case, and Fleck's status as an UnreliableNarrator make it impossible to discern if he and Bruce are related.
210* In ''[[Literature/TedsCavingPage Living Dark]]'', Ted's friend B is changed into his estranged younger brother Brad.
211* Creator/IngmarBergman's and Creator/KennethBranagh's film adaptations of ''Theatre/TheMagicFlute'' both make Sarastro Pamina's father.
212* In the Franchise/MarvelCinematicUniverse:
213** In ''Film/{{Thor}}'' and its sequels:
214*** Variation with ComicBook/{{Hela}} in ''Film/ThorRagnarok''. In the comics, she is ComicBook/{{Loki}}'s biological daughter or [[MultipleChoicePast was at least created by him]]. Here, [[spoiler:she is actually Odin's biological daughter and the [[LongLostRelative long-lost older sister]] of Thor (and Loki by adoption). This means that while she is no longer biologically related to Loki, she ''is'' now related to Thor]]. This also makes her a CompositeCharacter with [[spoiler:ComicBook/{{Angela|AsgardsAssassin}}, who is the comic universe's lost sister]].
215*** In the comics, Frigga is Thor’s stepmother. Here, she is his biological mother.
216** In the comics, ComicBook/{{Ultron}} was built by ComicBook/AntMan and considers him his father. The MCU hadn't [[Film/AntMan1 debuted Ant-Man yet]], so the relationship was transferred to ComicBook/IronMan instead, complete with the resulting daddy issues.
217** In ''Film/GuardiansOfTheGalaxy2014'':
218*** In the comics, [[Characters/GuardiansOfTheGalaxyModern Gamora]] is ComicBook/{{Thanos}}' adopted daughter and top assassin, and [[Characters/GuardiansOfTheGalaxyModern Nebula]] is an independent space pirate who ''claims'' to be his biological granddaughter, but it's left ambiguous as to whether or not this is actually true. In the film, ''both'' women are adopted "daughters" of Thanos, and consider each other sisters. Other "children of Thanos" are shown in ''Film/AvengersInfinityWar'' and ''Film/AvengersEndgame''; in the comics they're Thanos' QuirkyMinibossSquad the "ComicBook/BlackOrder" but for the most part not a family[[note]]Corvus Glaive and Black Dwarf are brothers and Corvus is married to Proxima Midnight; but the rest are unrelated[[/note]] and have no direct connection to either Gamora or Nebula.
219*** In both the comics and film, [[ComicBook/StarLord Peter Quill]] is a HalfHumanHybrid with a human mother. While the original film left the identity of the father open as a SequelHook, WordOfGod stated that it is not J'Son of Spartax as it is in the comics. ''[[Film/GuardiansOfTheGalaxyVol2 Vol. 2]]'' reveals that Quill is now the son of Ego the Living Planet. ''Film/TheGuardiansOfTheGalaxyHolidaySpecial'' subsequently confirms that [[spoiler:Mantis was another of Ego's children, making her Peter's half-sister]].
220** In ''Film/SpiderManHomecoming'', [[spoiler: the Vulture turns out to be Liz Allan's father]]. This ended up making them both {{Composite Character}}s of, respectively, [[spoiler:the ComicBook/UltimateMarvel version of [[ComicBook/UltimateXMen The Blob]] (being a supervillain who's the father of his universe's Liz Allan) and Valeria Toomes from the mainstream continuity (being the Vulture's daughter).]]
221** ''Film/{{Black Panther|2018}}'' films:
222*** [[spoiler:Erik Killmonger turns out to be the cousin of T'Challa and Shuri]], which is a connection that doesn't exist in the comics. By extension, this makes [[spoiler:T'Challa and Shuri's father T'Chaka the older brother of Killmonger's father N'Jobu.]]
223*** There is also Ramonda. In the comics, she is the stepmother of T'Challa and served as a surrogate mother to him after T'Challa's own mother died giving birth to him. In the MCU, Ramonda is T'Challa's biological mother.
224*** Shuri is T’Challa’s half sister in the comics but is his full sister in this universe.
225*** Okoye is W'Kabi's wife.
226** ''Film/AntManAndTheWasp'' portrays Ghost as Elihas Starr's daughter, with [[spoiler:Bill Foster becoming her surrogate father after her real parents are killed]].
227** ''Film/AvengersEndgame'':
228*** [[spoiler:During the TimeSkip, Tony and Pepper end up married. In the comics, during the few times their relationship turned romantic, it never got that far. Combined with RelatedDifferentlyInTheAdaptation, AgeLift, and GenderFlip, Morgan Stark is their daughter; in the comics, Morgan was a male cousin of Tony's around the same age as him (and combined with AdaptationalHeroism as the Morgan of the comics is a CorruptCorporateExecutive and a dick to Tony).]]
229*** [[spoiler:Steve ends up going back in time and marrying ComicBook/PeggyCarter.]]
230** In ''Film/BlackWidow2021'' Yelena Belova and Natasha Romanoff are portrayed as sisters, while their comic counterparts were childhood rivals. In the comics there is flirty back and forth between them. Furthermore, Melina Vostokoff (Iron Maiden) and Alexei Shostakov (Red Guardian) are portrayed as their foster parents... sort of (it was a cover identity, but Yelena [[spoiler:and indeed most of them]] [[ItMeantSomethingToMe felt like it was real]]). Alexei is RelatedDifferentlyInTheAdaptation to Natasha, however, as his comic counterpart was her ex-husband.
231** In ''Film/ShangChiAndTheLegendOfTheTenRings'', ComicBook/ShangChi is made the son of the Mandarin, a character he has no connection to in the comics. This is because his original father, Literature/FuManchu, was [[ExiledFromContinuity off limits for legal reasons]] (as well as widely being considered a racist caricature). This also extends to his sister, Fah Lo Suee (who is [[AdaptationNameChange renamed Xialing]]).
232* In the 1996 film of ''Film/{{Matilda}}'', Miss Trunchbull is the stepsister of [[spoiler: Miss Honey's late mother]] rather than her biological sister as she is in [[Literature/{{Matilda}} the book]]. It seems the screenwriters didn't want the BigBad to be the biological aunt of [[spoiler: Matilda's loving ParentalSubstitute]]. [[Theatre/{{Matilda}} The stage musical]], on the other hand, keeps her as a sister, but [[Film/RoaldDahlsMatildaTheMusical the film of the musical]] also changes her to a stepsister, likely because [[spoiler: Miss Honey and her parents are given a RaceLift, but Trunchbull isn't]].
233* In the 1980 Literature/MissMarple film ''The Mirror Crack'd'', Inspector Craddock is Miss Marple's "favorite nephew". In ''Literature/TheMirrorCrackdFromSideToSide'' (and ''only'' in that book) he calls her "Aunt Jane", but she's only an HonoraryAunt.
234* In ''Film/MortalKombatAnnihilation'', Raiden and Shao Kahn are revealed to be brothers. And later it's revealed that Shinnok is their father. Which isn't canon in the video games, except for the equally non-canon ''[[VideoGame/MortalKombatVsDCUniverse Mortal Kombat vs. DC Universe]]''.
235* The ''ComicBook/NickFury: Agent of S.H.I.E.L.D.'' TV movie made Viper the daughter of Baron von Strucker.
236* ''Film/OzTheGreatAndPowerful'' keeps the Wicked Witches as siblings and also makes Glinda the daughter of the former king of Oz. [[ContinuitySnarl When the former king exists]] in the book series, he has no relation to Glinda, being the father of Ozma (who tends to be AdaptedOut), making the film's Glinda a CompositeCharacter of the two.
237* In ''Literature/PaddingtonBear'', Mrs. Bird was originally the Brown's housekeeper. It would be very unusual for a present-day middle class English family to employ a live-in housekeeper, so in ''Film/Paddington2014'' she is described as a relative, though what relationship she has to any of them is never stated.
238* ''Film/PunisherWarZone'':
239** In its use of characters from both [[ComicBook/ThePunisher the mainstream books]] and [[ComicBook/ThePunisherMAX the MAX series]], makes Jigsaw the nephew of Jennifer Cesare's grandfather, Don Cesare [[spoiler:as Jigsaw didn't appear in the MAX series until the "Girls in White Dresses" arc a few months before the film's release where the Heavy was revealed to be Jigsaw's MAX incarnation]].
240** Nick Cavella's henchmen, Pittsy and Ink, are unrelated thugs in the comic but father and son in the film.
241* ''Literature/TheSecretGarden:'' Both the 1993 and 2020 adaptations make Colin and Mary's respective mothers into twins, presumably to a.) emphasize their BondingOverMissingParents and b.) facilitate the idea that Mary resembles them both. It's combined with UnrelatedInTheAdaptation, since in the book, Lillias was Mary's father's sister, not her mother's. Also see below under "Theatre."
242* ''Film/SilentHillRevelation3D'' makes Claudia and Vincent mother and son, whereas they are unrelated individuals in ''VideoGame/SilentHill3''. Also, the filmmakers apparently forgot this, but in [[Film/SilentHill the original film]], Christabella is Dahlia's sister, which means that Claudia is Heather's aunt and [[KissingCousins Vincent is her cousin]].
243* In the [[Film/SnowWhite1916 1916 film adaptation]] of ''Literature/SnowWhite'', Snow White and the prince are KissingCousins.
244* In ''Film/{{Spectre}}'', we find out that [[spoiler:Blofeld is Bond's older stepbrother and that his entire motivation stems from the belief that their father loved James more]].
245* In the ''Literature/{{Stargirl}}'' book, Hillari Kimble and Danny aren't related. They're siblings in the ''Film/{{Stargirl}}'' film. Hillari now hates Stargirl for [[ItsPersonal getting her brother into a bike accident]], rather than just hating Stargirl because she's an AlphaBitch.
246* In ''Film/StreetFighterTheLegendOfChunLi'', Rose is M. Bison's young daughter.
247* ''{{Film/Timeline}}'': Chris is turned into Professor Johnston's son whereas in the book the latter is only a father ''figure'' for him. Claire becomes Arnaud's sister.
248* May have been intended in the ''Film/{{Transformers|FilmSeries}}'' film franchise when Optimus Prime calls his arch-nemesis Megatron "brother" even thought they're robots. Also making this example a sort of CainAndAbel.
249* Many (but not all, there's a lot of debate in that area, even in ancient times) scholars believe that Achilles and Patroclus were lovers (Patroclus definitely was a close friend and mentor to the somewhat younger Achilles), but they were made cousins (and the age and mentor-student relationship reversed) in the 2004 movie ''Film/{{Troy}}'' and the insistence on this being the reason for their closeness (and Achilles' RoaringRampageOfRevenge when Patroclus is killed) bordered on HaveIMentionedIAmHeterosexualToday. Creator/CleolindaJones mocked this change mercilessly in her parody of the film.
250** This example is a subversion however, as Patroclus and Achilles really were related, albeit in a different way from the movie: Patroclus' grandmother Aegina was Achilles' great-grandmother, making Patroclus Achilles' first cousin once removed.
251** In the same movie, Briseis is the cousin of Hector and Paris while in ''Literature/TheIliad'', she's not even a Trojan.
252* ''Film/WarCraft2016'': Happened to several characters from the game in this film.
253** Orgrim Doomhammer and Durotan were originally from different clans, Blackrock and Frostwolf, and their friendship was considered [[OddFriendship unusual]] among orcs. Here, Orgrim is a Frostwolf and Durotan's second in command.
254** Taria Wrynn, Llane's wife and Lothar's sister, didn't exist in the original and so didn't this link between Lothar and Llane.
255** Garona, who was [[spoiler:Medivh's lover]] (see FanonDiscontinuity) in the original, is implied to be [[spoiler:his daughter]] here.
256* In ''Film/TheWizardOfOz1925'', Dorothy, not Ozma, is the daughter of King Pastoria.
257* ''Film/TheWizardOfOz'' turns the Wicked Witches from ''Literature/TheWonderfulWizardOfOz'' into sisters. Quite a few later adaptations of the book also make this change with some, such as ''Theatre/TheWiz'' and ''Film/TheMuppetsWizardOfOz'', even turning all four of the witches into sisters.
258* ''Film/XMenFilmSeries''
259** ''Film/X2XMenUnited'' did this with Jason Wyngarde/Mastermind by making him a CompositeCharacter of his comic self and William Stryker's unnamed mutant son from ''ComicBook/GodLovesManKills''. This also entailed Jason getting an AgeLift, as his comic counterpart was far too old to have been William's son.
260** ''Film/XMenOriginsWolverine'' makes ComicBook/{{Sabretooth}} Wolverine's half-brother (as opposed to simply being another Weapon X experiment). Though it seemed to be {{Fanon}} before the movie was filmed, due to Dog Logan (Wolverine's half-brother in the comic) having a resemblance to Sabretooth in the end. This also makes him a CompositeCharacter.
261** In ''Film/XMenFirstClass'', Charles Xavier and ComicBook/{{Mystique}} are foster siblings.
262** ''Film/{{Logan}}'' sees Rictor as part of the same program that created ComicBook/{{X 23}}. Additionally, his source DNA/biological father is listed in his file as Dominic Petros[[note]]which itself in an alias in the comics, as his real name is Dominikos Petrakis[[/note]], a.k.a. Avalanche.
263** ''Film/Deadpool2'':
264*** Hope Summers is ComicBook/{{Cable}}'s biological daughter instead of a child he adopts.
265*** Juggernaut wears a helmet to stop his wheelchair-bound brother from reading his mind. He doesn't mention Xavier by name, but he says brother rather than stepbrother.
266[[/folder]]
267
268[[folder:Gamebooks]]
269* ''Literature/LoneWolf'': In ''Fire on the Water'', Lone Wolf meets separately with both Durenese Lord Axim of Ryme and Viveka the mercenary woman, but there is no hint they could be related. In the ''Legends of Lone Wolf'' novelization, those two are father and daughter.
270[[/folder]]
271
272[[folder:Literature]]
273* ''Literature/AlwaysOctober'' (by Creator/BruceCoville):
274** In the original short story "My Little Brother Is a Monster", Jason Burger and his mom adopt Dum Pling / Little Dumpling as a part of their family, but do not share blood with him. In the full novel, Jason is replaced with Jacob Doolittle, whose grandfather Arthur was married twice; his first wife, Tia [=LaMontagne=] (alias Teelamun) had two children, Meer Askanza (the mother of Little Dumpling) and Mazrak. After she disappeared and Arthur remarried, his second wife bore him a son, Jacob's father. This makes Little Dumpling into Jacob's paternal cousin by blood (and by extension his mother into Jacob's aunt), and Mazrak into both Jacob and Little Dumpling's uncle.
275** In the original short story, only one member of the Council of Poets -- Keegel Farzym -- was related to Dum Pling. In this version, another of them is his maternal grandmother Teelamun.
276* In the Franchise/SherlockHolmes spin-off novel ''The Beast of the Stapletons'', a sequel to ''Literature/TheHoundOfTheBaskervilles'' by Creator/JamesLovegrove, the villain is revealed to be [[spoiler:Doctor Mortimer, who Holmes learns is the step-brother of Professor Moriarty]].
277* The book ''By Pipe or Pen'' is a prequel for several fairy tales, but the big twist of who the two protagonists, Felix and Robin, become means Literature/ThePiedPiperOfHamelin is the half brother of [[spoiler:''Literature/{{Rumpelstiltskin}}''.]]
278* ''Literature/TheMistsOfAvalon'' practically condenses all of Myth/ArthurianLegend into one TangledFamilyTree, possibly just to facilitate [[AuthorAppeal lots of incest]].
279** Most notably, this is the TropeCodifier of Morgan ([[MyNaymeIs or in this series, Morgaine]]) le Fay being Mordred's mother instead of Morgause (his foster mother in this version). Also, Igraine and Viviane (Myth/TheLadyOfTheLake) are sisters (as is Morgause, [[RelatedDifferentlyInTheAdaptation who's normally Igraine's daughter]]). Igraine's father is [[DecompositeCharacter the first]] Merlin, whose youngest daughter is Niniane. Viviane is also the biological mother of Lancelet, as opposed to his foster mother, meaning that he is now KissingCousins with both Morgaine and Arthur. She's also the mother of Balan, which becomes his motive for killing his (now adoptive) brother Balin.
280** Gwenhwyfar's sister is set up to be this setting's version of Isolde, [[AbortedArc only to suddenly die]] before that story can happen. Meanwhile Maleagant [[MamasBabyPapasMaybe may or may not]] be their half-brother. ([[VillainousIncest This doesn't stop him from raping Gwen]].) The Elaine of Corbenic analogue is their cousin, whose father is King Pellinore. Nimue ([[DecompositeCharacter who's different than Niniane or Viviane]]) is her and Lancelet's daughter.
281* In Evangeline Walton's ''The Song of Rhiannon'', a retelling of the third branch of Literature/TheMabinogion, Manawyddan, who is Pryderi's step-father in the original legend, is his biological father instead, having conceived him of Pwyll's behalf after the latter realized he was infertile. Everybody however still believes the boy to be Pwyll's son.
282* In ''Literature/TheSquiresTales,'' Tristram and Dinadan are brothers who hardly know each other instead of being friends.
283** Bedivere is referred to as both Kai and Arthur's cousin. (Whether that means he's related to both of them by blood or he's Arthur's cousin by adoption isn't clear.) In contrast, Culloch and Arthur are UnrelatedInTheAdaptation.
284** Luneta is the daughter of Gaheris and Lynet, which also makes her Ywain's cousin.
285* ''Literature/TheSurvivingTwins'' is a retelling of ''Literature/SnowWhiteAndRoseRed'' that reveals [[spoiler:the dwarf]] to be [[spoiler:the girls']] father whose memories have been stolen.
286* ''Literature/ATaleOf'':
287** ''A Tale of the Wicked Queen'' has the Queen from ''WesternAnimation/SnowWhiteAndTheSevenDwarfs'' being the daughter of [[spoiler:the Man in the Mirror]]. This explains her obsession with it. [[spoiler:Her father was extremely abusive and hated his daughter in life. He died scorning her and ended up causing her to have [[IAmNotPretty major self-esteem issues]]. As the Slave, however, he cannot tell a lie and is forced to tell her what she wants. She takes comfort in having her father tell her that she is the [[WorldsMostBeautifulWoman most beautiful in all the land]].]]
288** In ''A Tale of the Sea Witch'' Ursula is Triton's sister. This is reused from early ''WesternAnimation/{{The Little Mermaid|1989}}'' scripts.
289** ''A Tale of the Dark Fairy'' reveals that Maleficent is the adopted niece of Cinderella's Fairy Godmother. Maleficent is also the mother of [[spoiler:''Aurora'', who was born from a [[TrulySingleParent magical spell]].]]

291
292[[folder:Live-Action TV]]
293* ''The New Addams Family'':
294** The show is a remake of ''Series/TheAddamsFamily'' that used elements of [[Film/TheAddamsFamily the film series]]. The remake of the original series' HalloweenEpisode "Halloween with the Addams Family" had the notable change of making it so that the two crooks attempting to rob the Addams Family were father and son.
295** Like the movies, this series made Fester into Gomez's brother instead of Morticia's uncle, but kept Grandmama as Gomez's mother instead of making her Morticia's mother as the movies did, so for the first time in the franchise, Grandmama and Fester were mother and son instead of just in-laws.
296* ''Series/AllTheLightWeCannotSee'': In the book, Mme. Manec is Etienne's KindlyHousekeeper. In the show, she is his sister and thus also Daniel and Marie-Laure's aunt.
297* In ''Series/AlteredCarbon'' [[spoiler: Reileen]] was compiled with Takeshi Kovacs' unnamed sisters. [[spoiler: And acquired an almost incestuous obsession with him.]]
298* The ''Series/{{Arrowverse}}'':
299** ''Series/{{Arrow}}'':
300*** Thea Dearden Queen is basically Mia Dearden reinvented as Ollie's sister. Additionally, she turned out to be the biological daughter of Malcolm Merlyn, ComicBook/GreenArrow's ArchEnemy in the comics, after having an affair with Oliver's mother. For the matter, Walter Steele becomes Oliver and Thea's stepfather while in the comics he's just a minor character.
301*** Yao Fei and Shado are re-imagined as father and daughter. The comic book counterparts have never even met.
302*** Nyssa Al-Ghul (Nyssa Raatko) [[spoiler: was married to Oliver]] in the show. They are total strangers in the comics.
303*** Noak Kuttler aka The Calculator, a ''ComicBook/BirdsOfPrey'' villain, becomes the father of Felicity Smoak, a minor ''ComicBook/FirestormDCComics'' character.
304*** Husband and wife John Diggle and Lyla Michaels-Stewart/Harbinger ended up becoming this after season 7 revealed that Diggle was a case of CanonCharacterAllAlong: [[ComicBook/GreenLantern John Stewart]] (which ended up leading to ExpyCoexistence in the comics, as Diggle was ported over to the comics prior to this point). In the comics, Stewart and Harbinger were only allies. Also, thanks to [[spoiler:Ollie's son becoming a DecompositeCharacter, they're the parents of Connor Hawke]].
305** ''Series/TheFlash2014'':
306*** The show makes Barry an honorary member of the West family, after they took him in when Barry's mom was murdered and dad was jailed for it. While Barry does see Joe West as something of a ParentalSubstitute, his relationship with Iris West is unchanged, making it more of a ChildhoodFriendRomance in this verse.
307*** Also involving the West family, Wally West is introduced as the brother/son that Iris and Joe [[LongLostRelative never knew they had]], where in the comics he's Iris' nephew. This in turn makes Barry his surrogate brother instead of his uncle or merely his aunt's boyfriend.
308*** In the comics, Axel Walker is a LegacyCharacter inspired by the original Trickster. In the show, he turns out to be the original Trickster's bastard son. As the main Trickster is played ([[Series/TheFlash2014 as]] [[WesternAnimation/JusticeLeague always]]) by Creator/MarkHamill, we ''did'' get to hear the appropriate line from ''Film/TheEmpireStrikesBack'' when their relationship, a surprise to the viewer ''and'' the second Trickster, was revealed.
309*** Ronnie Raymond and Caitlin Snow are engaged throughout the first season and then married as of the first season finale. In the ''ComicBook/FirestormDCComics'' comics, they're ''enemies'' as Caitlin's comics counterpart is an evil supervillain, Killer Frost. Caitlin did eventually start turning into Killer Frost thanks to WithGreatPowerComesGreatInsanity, but by that point [[spoiler:she had been widowed for some time, as Ronnie had made a HeroicSacrifice almost immediately after they eloped]].
310*** Jesse Quick is the daughter of WWII heroes Johnny Quick and Liberty Belle in the comics; in the show she's the daughter of CanonForeigner Harrison Wells.[[note]]Well, an AlternateUniverse Wells; the main-universe Wells died childless.[[/note]]
311*** Savitar is [[spoiler: Iris' fiancé through his own past/alternate self, Barry]].
312*** [[spoiler:In ''DC Rebirth'', Barry had a daughter named Nora with Jessica Cruz, the first female ''ComicBook/GreenLantern'' from Earth. Here, Iris is her mother]].
313*** Jay Garrick and Barry Allen have no familial connection in the comics. On the show [[spoiler: Jay is the AlternateUniverse counterpart of Barry's father Henry Allen, giving them a kind of father-son relationship, biologically at least. Likewise, Jay's wife Joan Williams, who also has no family-relationship with Barry in the comics, is a doppelganger of his mother Nora Allen in this verse.]]
314** ''Series/LegendsOfTomorrow'': The show features Sara Lance donning the White Canary identity, making the character related to the entire ComicBook/BlackCanary family. In the comics, the White Canary is [[AdaptationalHeroism a villain]] and self-appointed ArchEnemy of Black Canary.
315** ''Series/{{Supergirl 2015}}'':
316*** The show re-imagined Non, one of General Zod's CoDragons in ''Film/SupermanII'' and the comics, as ComicBook/{{Supergirl}}'s EvilUncle through his marriage to her mother's EvilTwin. This also makes him a part of ComicBook/{{Superman}}'s extended family.
317*** The show's version of Otis is the brother of Mercy Graves.
318** ''Series/SupermanAndLois'':
319*** [[spoiler: In the ''ComicBook/{{Steel}}'' comics, Natasha Irons is the titular character's niece. Here, Natasha is the daughter of Steel and an alternate universe version of Comicbook/LoisLane.]]
320*** In a Season 1 twist, [[spoiler:Morgan Edge is revealed to be Lara Lor-Van's son from a prior marriage, and thus Superman's older half-brother]].
321* ''Series/BattlestarGalactica2003'':
322** WordOfGod from the showrunners of the ''Galactica'' prequel ''Series/{{Caprica}}'' is that the Eights are based on Admiral Adama's deceased half-sister Tamara. Which, if true, means that she is in fact, like, a niece.
323** Boomer is also an instance of Number Eight in the re-imagined series, so this Lieutenant Boomer and Lieutenant Athena are "identical twins", whereas the original ''Galactica'''s Lieutenant Boomer ([[GenderFlip who was a man]]) and Lieutenant Athena were completely unrelated.
324* ''Series/TheBoys2019'': [[Recap/TheBoysS03E07HereComesACandleToLightYouToBed The penultimate episode of Season 3]] reveals that the unrelated in the comics [[spoiler:Soldier Boy and Homelander]] are here father and son, respectively.
325* ''{{Series/Camelot}}'' does likewise - Morgan and Arthur are related through Uther rather than Igraine.
326* ''{{Series/The Chosen|TVSeries}}'': In Literature/TheFourGospels, Simon the Zealot and the lame man at the Pool of Bethesda have zero relation to one another. In the show, Simon and the man [[NamedByTheAdaptation (given the name Jesse here)]] are brothers.
327* In ''ComicBook/CloakAndDagger'' comics, Tyrone Johnson had a friend called Billy who he saw get shot by a cop. In the [[Series/CloakAndDagger2018 TV series]], Billy was his older brother.
328* In ''Series/DoomPatrol2019'', Niles Caulder is Dorothy Spinner's father. In the comics, they were not related and the only information given about Dorothy's parentage was that she was raised by AbusiveParents who were retroactively established to be her adoptive parents in John Arcudi's run with no information given about her biological parents aside from her birth mother still being alive, but unable to meet with her for unexplained reasons.
329* "[[Recap/FateTheWinxSagaS1E6AFantaticHeart A Fanatic Heart]]", the last episode of season 1 of ''Series/FateTheWinxSaga'' reveals that [[spoiler:Beatrix was adopted and raised by Sky's father]], technically making them adopted siblings. [[spoiler:Sky had no such connection to any of the Trix]] in the ''WesternAnimation/WinxClub''.
330* ''Series/TheFlash1990'':
331** The series re-imagined Jay Garrick as Barry Allen's older brother. In the comics, Jay Garrick is merely Barry's predecessor as ComicBook/TheFlash.
332** During the series's later crossovers with the ''Arroverse'', it's revealed Barry and Tina got married. In the comics, Barry never even met Tina, who interacted with Wally West shortly after Barry died.
333* ''Series/GameOfThrones''
334** A major StoryArc in Season 5 has [[spoiler:Sansa Stark]] being put in an ArrangedMarriage with [[spoiler:Ramsay Bolton]]. In [[Literature/ASongOfIceAndFire the source material]], this storyline [[CompositeCharacter belongs to Jeyne Poole, the first spoiler-tagged character's best friend]].
335** An inverted example happens in Season 6. In the source material, Arya Stark is the actress playing "Sansa" in the Essos theater group. The show pulls a DecompositeCharacter move by making a CanonForeigner unrelated to the Starks fill the role and giving Arya a slightly altered arc.
336** [[spoiler: The Season 7 finale reveals that Rhaegar Targaryen and Lyanna Stark eloped and secretly married. While a very popular theory (if not the most) among book readers, the source material has yet to officially confirm this matter.]]
337* In the Creator/SkyOne adaptation of ''Film/GoingPostal'', "Princess", the very young clacks tower operator, becomes the granddaughter of Grand Trunk engineer Mr Pony.
338* Freddy Martinez and Cara, best friends in the ''Literature/{{Goosebumps}}'' book ''Literature/VampireBreath'', are said to look like siblings. When it was adapted into a TV episode, they are actually siblings. [[spoiler:They learned that they're vampires and Count Nightwing is their grandpa. While in the book, only Fred is a vampire, while Cara becomes a werewolf...]]
339* ''Series/{{Gotham}}'':
340** Silver St. Cloud is a member of the Dumas Family (a.k.a. the Order of St. Dumas).
341** Jervis Tetch's Alice is his sister. [[BrotherSisterIncest This does not alter the nature of his obsession with her in any way]].
342** In the comics, Jim Gordon was married first to Barbara Kean and then to Sarah Essen, and Leslie Thompkins has never been married (she's occasionally Alfred's LoveInterest) but they’re married here.
343* ''Series/TheHauntingOfHillHouse2018'': In the original novel, the characters come from different families and are not at all related to each other. The Netflix adaptation shows all the main characters as part of the Crain family, with most of the major characters being siblings and the children of Olivia and Hugh Crain.
344* The [[Series/HawaiiFive0 remake]] of ''Series/HawaiiFiveO'' made Chin Ho and Kono cousins.
345* In ''Series/Hawkeye2021'', Kate's aunt, whose apartment she's using as a base, is Moira Brandon. In the comics, Moira Brandon is the previous owner of the building that became the Comicbook/WestCoastAvengers Compound. First mentioned as an UnseenCharacter in the eighties, she made one appearance (and died) in ''Avengers West Coast'' #100, more than a decade before Kate's comic book debut, and there is no known connection between them.
346* In the made-for-tv movie ''{{Series/Hercules}}'':
347** Antaeus - one of the many enemies Hercules fought during his labors - is made [[spoiler:Herc' true father instead of Zeus]].
348** Iole is made the daughter of Eurystheus and Megara.
349* ''Series/HerculesTheLegendaryJourneys'': Aphrodite, Apollo, and Artemis are all the children of Zeus and Hera. In the original myths, Apollo and Artemis were the children of Zeus and Leto, while Aphrodite was either created spontaneously when Ouranos' genitals were thrown into the sea or was the daughter of Zeus and Dione.
350* In ''Series/JessicaJones2015'', [[ComicBook/JessicaJones Jessica]] is the adopted sister of ComicBook/PatsyWalker, a character she has no connection to whatsoever in the comics.
351* ''Series/{{Krypton}}'' takes a cue from ''ComicBook/SupermanEarthOne'' and makes [[spoiler:General Zod the uncle of Superman.]]
352* In the ''Literature/LandOfOz'' books, Princess Langwidere is merely the niece of the King of Ev. In ''Series/EmeraldCity'', she is his daughter.
353* In the novel of ''Series/TheLeftovers'', Matt and Nora are not related at all; in the television adaptation, they are brother and sister.
354* ''Series/LetTheRightOneIn'': Mark (Håkan's equivalent) is the father of Eleanor (originally Eli) here. Originally they weren't related at all.
355* In ''Series/LukeCage2016'':
356** Cottonmouth and Black Mariah are now cousins; they originally had no connection to one another. The second season ties a third previously-unrelated villain into the family, bringing in Nightshade as Mariah's estranged daughter.
357** [[spoiler:Luke Cage and Diamondback]] are made half-brothers. They were always friends-turned-enemies in the comics, but now [[spoiler: Diamondback is a BastardBastard and has resentment for their father's legitimate son to fuel his hatred.]]
358* ''{{Series/Merlin 2008}}'':
359** Morgana turns out to be Arthur's half-sister through Uther. Traditionally, Arthur's mother Igraine is their shared parent.
360** Inverted with Gawain. He's Morgause's son in most of the legends, but here is a separate character. Morgause isn't even old enough to be his mother. Agravaine was also Morgause's son in the legends and actually Arthur's ''nephew'' - but in the series is Arthur's uncle, and is unrelated to Morgause because he's Igraine's brother and [[UnrelatedInTheAdaptation Morgause is no longer Igraine's daughter]].
361* ''Series/TheOldenDays'', a GagDub sketch based on ''Series/Rush1974'', uses footage of Miss Hawk (Mary Ward) as Ma Frontbottom, the Governor's mother. Miss Hawk had no relationship to Commissioner Fitzalan in ''Rush''.
362* Happens at several points in ''Series/OnceUponATime''. Due to the ArcWelding between several different tales, unrelated stories and characters are tied together into the same family.
363** Literature/{{Rumpelstiltskin}} is the son of [[spoiler: Literature/PeterPan]].
364** Regina, the Evil Queen from ''Literature/SnowWhite'', is the daughter of [[Literature/AliceInWonderland the Queen of Hearts]] (who is also the miller's daughter from ''Literature/{{Rumpelstiltskin}}'', with the Evil Queen being a GenderFlip of the baby from that story), and the sister of [[Literature/TheWonderfulWizardOfOz the Wicked Witch of the West]].
365** The families of Regina and Rumple are also tied to Snow White and Prince Charming through Emma, Neal, and Henry.
366** [[Literature/TheSnowQueen Gerda]] is the mother of [[WesternAnimation/{{Frozen|2013}} Elsa and Anna]], and the original Snow Queen is her sister Ingrid.
367** Played straight ''and'' inverted at the same time with the New Enchanted Forest version of [[WesternAnimation/{{Cinderella}} the Tremaine family]]. The "wicked stepmother" (in addition to being [[spoiler:Literature/{{Rapunzel}}]]) is actually Tremaine's ''first'' wife, meaning he's the biological father of Anastasia and Drusella and the stepfather of Ella; the exact reversal of the traditional version.
368** In the spinoff series ''Series/OnceUponATimeInWonderland'', it's implied but never confirmed that the Red Queen of Wonderland (who later marries the Knave of Hearts, who is actually [[Myth/RobinHood Will Scarlet]]) was one of Literature/{{Cinderella}}'s stepsisters. (Since they're so often combined in adaptations, it should be noted that the Red Queen and the Queen of Hearts are not the same person in ''Once'', although the former was a friend and pupil of the latter in this version, [[AdaptationOriginConnection whereas the originals didn't meet]]).
369** The seventh season has Henry fulfilling the traditional role of Cinderella's prince, so now Cinderella's prince is the son of Snow White's Evil Queen.
370** The version of [[Literature/AliceInWonderland Alice]] who appears in Season 7 is the daughter of [[Literature/PeterPan Captain Hook]] and [[Literature/{{Rapunzel}} Mother Gothel]].
371* The [[Series/OrphanBlack7Genes Japanese remake]] of ''Series/OrphanBlack'' made the counterpart of Sarah Manning and Helena's birth mother Amelia and the counterpart of Siobhan Sadler (Sarah's foster mother) sisters. They're complete strangers to each other in the original.
372* ''Series/{{Peacemaker|2022}}'' does this by way of CompositeCharacter, having Christopher's father Auggie Smith also be the racist supervillain White Dragon. In the comics, White Dragon was a completely unrelated character named William Heller.
373* The ''Creator/AgathaChristie's Series/{{Poirot}}'' often adds familial relationships not present in the original ''Literature/HerculePoirot'' novels.
374** The adaptation of ''Literature/CardsOnTheTable'' adds a mother-daughter relationship between two of the suspects, partly in order to make [[spoiler:the older woman's protection of the younger woman]] more plausible.
375** In ''Third Girl'', Frances Cary becomes a half-sister of Norma Restarick, whose father left her mother for her teacher, Miss Battersby, with whom he had a relationship.
376** The adaptation of ''Literature/AppointmentWithDeath'' makes both Dr. Theodore Gerard and Dame Celia Westholme the actual, biological parents of Jinny Boynton. In the novel, Jinny is the only biological child of Mrs. Boynton, is unrelated to Celia Westholme, and is the eventual LoveInterest of Dr. Gerard.
377** Agent Colin Lamb from ''Literature/TheClocks'' is heavily in the books to be the son of Superintendent Battle. In the adaptation, he's renamed to Colin Race, and is explicitly said to be Colonel Race's son.
378* The main characters of ''Series/ThePrincessWeiYoung'' are highly fictionalised versions of historical figures, and the series takes liberties with how some of them were related to each other. Historically Tuoba Hong was the son of Consort Li (fictionalised as Li Chang Le) and the step-son of Empress Feng (fictionalised as Xin Er). In the series Hong is the son of Xin Er and [[UnrelatedInTheAdaptation isn't related to Chang Le]], who died before he was born.
379* In the TV adaptation of ''Series/Runaways2017'', Molly is now Gert's adopted younger sister.
380* ''Series/RuyisRoyalLoveInThePalace'': Records are scarce, but it's unlikely Empress Xiaojingxian was closely related to Empress Nara. (In fact it's debatable if they even belonged to the same clan.) In the series, on the other hand, they're aunt and niece.
381* ''Series/{{Smallville}}'': Doomsday is the son of General Zod and Faora (he was conceived from their genetic samples and experimented on to receive his advanced powers).
382* ''Series/TheSnowQueen2002'': The witch, the princess, and the robber girl's mother are turned into the Spring Witch, the Summer Princess, and the Autumn Robber, {{Anthropomorphic Personification}}s of the seasons like the Snow Queen, and are the Snow Queen's sisters.
383* Done multiple times in adapting ''Franchise/SuperSentai'' into ''Franchise/PowerRangers'':
384** In ''[[Series/MightyMorphinPowerRangers Mighty Morphin' Power Rangers]]'', Season 3 introduces Rita Repulsa's family; her brother Rito Revolto and father Master Vile. While Vile's and Rito's counterparts were father and son in ''[[Series/NinjaSentaiKakuranger Kakuranger]]'', Rita's was part of [[Series/KyoryuSentaiZyuranger another series]] altogether. Additionally, Dai Satan was Witch Bandora's boss and [[Series/GoseiSentaiDairanger Emperor Gorma XV]] likewise never met Bandora, Yokai Daimao, and Gasha Dokuro, but Lord Zedd, [[CompositeCharacter a fusion of Dai Satan and Emperor Gorma XV/Lt. Colonel Shadam]][[note]]with a side of DecompositeCharacter as Dai Satan's footage was used for Lokar and the Gorma costume was the basis for [[Series/PowerRangersWildForce Master Org]] years later[[/note]], married Rita and thus has Rito and Vile as in-laws.
385** ''[[Series/PowerRangersMegaforce Megaforce]]'' would do something similar, making Vrak, the counterpart of ''Series/TensouSentaiGoseiger'''s main antagonist, Brajira, part of the Royal family of the Armada, whereas in ''Series/KaizokuSentaiGokaiger'' Brajira never personally met any of the Zangyack's royal family.
386** Inverted ''and'' played straight in ''[[Series/PowerRangersNinjaSteel Ninja Steel]]''. In ''[[Series/ShurikenSentaiNinninger Ninninger]]'', the Red and White Rangers were siblings and the other core Rangers were their cousins, while [[SixthRanger Starninger]] was unrelated to them. In ''Ninja Steel'', the core Rangers are unrelated while the Red and Gold Rangers are brothers.
387** During their appearance on ''Ninja Steel'', it's revealed that Tommy and Kat got married. None of the Sentai Rangers that made up Tommy married their respective series' Pink Ranger[[note]][[Series/KyoryuSentaiZyuranger Burai]] died, [[Series/GoseiSentaiDairanger Kōu]] was a kid, and ''Series/NinjaSentaiKakuranger'' and ''Series/BakuryuuSentaiAbaranger'' didn't even have a respective Pink Ranger for their teams (though Asuka was married to one of the villains in the latter)[[/note]].
388** ''Series/PowerRangersOperationOverdrive'''s Thrax-while sharing a counterpart to Bandora's son Kai-his Sentai counterpart from Overdrive isn't related to Witch Bandora either, nor Dai Satan, Emperor Gorma XV, or Lt. Colonel Shadam.
389** ''Series/PowerRangersMysticForce''...kinda does this? While Witch Bandora and [=MagiMother=] are played by the same actress, it's only in Mystic Force that they're the same person. Inverted and somewhat played straight with the main Ranger team as well. In ''Series/MahouSentaiMagiranger'', the entire team is related ''somehow'', but not in Mystic Force; in fact, Mystic Force plays more into the UnrelatedInTheAdaptation trope. Nick is the only character related to Leonbow and Udonna. Daggeron is only connected as a 3rd mentor and never marries any of the female members of the team nor is in any relationships with them beyond mentor[[note]] to most of the team[[/note]]/student[[note]] of Leonbow prior to the start of the show[[/note]]/fellow Ranger. Madison and Vida Rocca are sisters, but they don't have any other siblings. None of the other characters are mentioned as having siblings save Nick, who was adopted and has at least 1 sibling-an older sister.
390* ''Series/TrueBlood'': Tara and Lafayette were not related in ''Literature/TheSouthernVampireMysteries'', but in the show, they are cousins.
391* ''Series/TheTwilightZone1985'': In "Shadow Play", two [[DreamPeople characters]] in Adam Grant's [[RecurringDreams recurring nightmare]], Father Grant and Carol Ritchie, are his late father and his sister in the real world. In the [[Recap/TheTwilightZone1959S2E26ShadowPlay original episode]], the priest was Father Beaman, an actual priest who died when Adam was ten years old, while it is never said whether or not Carol is based on anyone from Adam's real life.
392* In the English dub of ''Series/{{Ultraman}}'', TagalongKid Hoshino is the younger brother of Fuji, the sole woman on the team. Although quite fitting, given the two's relationship, the problem is that Fuji is shown to have a little brother later on in the original Japanese version. The dub adjusts by changing the later-introduced kid to ''one of'' Fuji's brothers.
393* ''Series/TheWalkingDead'':
394** The Greene family ZigZagged this as the family relationship got shuffled a bit. In the comics, Hershel only had one late wife, while the TV show [[DecompositeCharacter split them in two]]. Of his canonical children, only Maggie retained her original status being his child from his first wife. Shawn was only his stepson here, while Arnold became the nephew of his first wife instead. The rest of the canonical children were AdaptedOut and was filled/replaced by [[CanonForeigner a daughter named Beth]].
395** Another possible remix. In the comics, Tyreese has a daughter named Julie. In the show, he has a younger sister named Sasha with no sign of Julie.
396** Speaking of Tyreese, he and Carol are essentially in a Common-Law marriage in the comics. They're not related at all in the show, and their only StoryArc together are during Season 4 and the premiere of the fifth involving her {{mercy kill}}ing his LoveInterest [[CanonForeigner in the show]] and them being stuck in the same party after their home base is destroyed.
397** Lilly Chambler became related to the Chambler ([[AdaptationNameChange Chalmers in the comics]]) family in virtue of being a CompositeCharacter of Lily Caul (her main counterpart) and April Chalmers. This also extends to Lilly's daughter Meghan, Caul's [[SparedByTheAdaptation stillborn child in the comics]].
398** Due to [[spoiler:Andrea]]'s [[DeathByAdaptation early death in the show]], Michonne fills her role in the comics as Rick's {{second|Love}} (Common Law) wife and stepmother to his children.
399[[/folder]]
400
401[[folder:Puppet Shows]]
402* In ''Film/TalesFromMuppetlandTheFrogPrince'', Robin not only isn't Kermit's nephew, he [[ForcedTransformation isn't really a frog]]. They gain their relationship in ''Series/TheMuppetShow'' and it's been that way ever since.
403[[/folder]]
404
405[[folder:Radio]]
406* Creator/TheBBC Radio Four series ''The Rivals'', in which Inspector Lestrade assists great 19th century detectives other than Literature/SherlockHolmes, the episode based on Arthur B. Reeve's ''Constance Dunlap, Woman Detective'', makes Dunlap into Lestrade's niece. This involves AdaptationalNationality (Reeves's Constance was American), probably AgeLift (Reeves's Constance was a married woman; the BBC version has just left university) and if not AdaptationalHeroism, exactly, then Adaptational Lawfulness (Reeves's Constance was a criminal as much as a detective).
407[[/folder]]
408
409[[folder:Theatre]]
410* ''Theatre/{{Beetlejuice}}'': In the film, Juno was merely BJ’s former boss. Here, she’s his ''mother''.
411* In Verdi's opera ''Falstaff'', based on ''Theatre/TheMerryWivesOfWindsor'', this trope is both played straight and inverted as Anne Page becomes [[AdaptationalNameChange Nannetta]] Ford, with her now-father Master Ford taking on Master Page's role in the action (the latter being {{Adapted Out}}) as well as his own, and her original mother Meg Page relegated to a smaller role.
412* In the stage adaptation of "Farewell, my Turnabout" from ''VisualNovel/PhoenixWrightAceAttorneyJusticeForAll'', Celeste Inpax is Adrian Andrews's cousin rather than her mentor.
413* In the 2014 American musical adaptation of ''WesternAnimation/{{The Hunchback of Notre Dame|Disney}}'', Claude Frollo is Quasimodo's uncle, his brother Jehan being the father.
414* In ''Theatre/TheKansasCollection'', Glinda is sisters with the Wicked Witch of the East. The Wicked Witch was once good before finding the Slippers.
415* Garsington Opera's version of ''Theatre/LOrfeo'' made the messenger Sylvia also Eurydice's mother, making the moment where she had to break the news of her death even more tragic.
416* In the [[Theatre/TheLittleMermaid stage musical]] of Disney's ''WesternAnimation/{{The Little Mermaid|1989}}'', Triton and Ursula are siblings. This ''was'' part of Disney's original concept for the movie, but it was [[WhatCouldHaveBeen dropped in development.]]
417* In ''Theatre/TheMarriageOfFigaro'', Barbarina is the daughter of the gardener Antonio, and Susanna's cousin, while Cherubino is a page with no connection to the judge Don Curzio. In ''¡Figaro! (90210)'', a 2015 adaptation of the opera reset in contemporary Beverly Hills, Barbarina's counterpart "Barbara" [[UnrelatedInTheAdaptation isn't related to Susana or to Atzuko (Antonio)]], but is the daughter of the Count and Countess's counterparts, Paul and Roxanne Conti. Meanwhile, "Li'l B-Man", Cherubino's counterpart, is the son of Don Curzio's [[GenderFlip gender-flipped]] counterpart Donna Curson.
418* In ''VideoGame/Persona3'', The male protagonist and female protagonist of ''Persona 3 Portable'' were counterparts that existed in parallel dimensions. While they still take each other's place in ''Theatre/Persona3TheWeirdMasquerade'', they are siblings there, with the performance featuring either one being the world where the other sibling died in their backstory.
419* WordOfGod is that the ''[[Anime/PokemonTheSeries Pokémon]]'' musical ''Theatre/PokemonLive'' implies that Giovanni is Ash's biological father. Delia was a part of Team Rocket as a teen and dated Giovanni, but left after meeting her future husband.
420* In ''Literature/TheQueenOfSpades'', Liza, while still a distant relative of the Countess, is treated pretty much as a servant, or even worse sometimes (it's mentioned that her salary is paid very inaccurately). In the [[Theatre/TheQueenOfSpades opera]], however, she is the Countess' granddaughter, thus having a much better social standing.
421* In the original cartoon version of ''WesternAnimation/ReallyRosie'', Chicken Soup is Rosie's [[PuppyLove "boyfriend."]] In the 1980 stage musical, which played off-Broadway and is now a staple of schools and children's theatre, he's her AnnoyingYoungerSibling. Kathy and Alligator also became brother and sister.
422* ''Theatre/TheSecretGarden:'' [[LostInImitation As in multiple films]], Mary's mother [[NamedByTheAdaptation Rose]] and Colin's mother Lily ([[AdaptationalNameChange whose name was Lilias in the book]]) were twin sisters, while in the [[Literature/TheSecretGarden book]], Mary's father was Lilias's brother.
423* In ''Theatre/{{Seussical}},'' [=JoJo=] is an AscendedExtra and the Mayor of Whoville's son, a move which was repeated in the ''[[WesternAnimation/HortonHearsAWho2008 Horton Hears a Who!]]'' film.
424* In the original penny dreadful and early theatrical treatments of ''Theatre/SweeneyToddTheDemonBarberOfFleetStreet'', Johanna has no personal connection to Sweeney and only investigates him because she suspects her missing boyfriend has been done in by the SerialKiller barber. Starting in the 1973 stage adaptation, she's Todd's daughter, whom his arch-enemy adopted after having convicted him on a false charge.
425* In the 1994 musical ''A Tale of Literature/{{Cinderella}}'' (not to be confused with ''Theatre/RodgersAndHammersteinsCinderella''), Cinderella's fairy godmother, La Stella, is also her grandmother, the mother of her MissingMom Giametta.
426* In the 2013 Starkid musical, ''Theatre/TwistedTheUntoldStoryOfARoyalVizier'' (a parody/retelling of Disney's ''WesternAnimation/{{Aladdin}}''), Ja'far is revealed to be [[spoiler:Jasmine]]'s father.
427* ''Theatre/AVeryPotterSequel'', Draco finds out that he is not truly Lucius's son, but rather his biological father is ''[[spoiler:Dobby]]'', born after Narcissa had an extramarital affair with him.
428* ''Theatre/{{Wicked}}'':
429** Subverted. In the [[Literature/{{Wicked}} original book]] it's intentionally vague if Nessarose is [[MamasBabyPapasMaybe Frexspar's or Turtle Heart's daughter]]. The musical AdaptedOut Turtle Heart, making Nessarose into Frex's biological daughter for sure. [[Literature/ALionAmongMen Two books later]] it was confirmed that Nessarose is also Frexspar's daughter in book canon.
430** This trope is played straight in books and musical alike with Nessarose and Elphaba, though: the two wicked witches in ''Literature/TheWonderfulWizardOfOz'' aren't related, but here they're sisters [[spoiler: (actually half-sisters)]], as in [[Film/TheWizardOfOz the classic film]].
431* In ''Theatre/TheWiz'', Addapearle, The Good Witch Of The North, mentions that she is the sister of the Wicked Witch Of The East, Evamean. It also makes her sisters with Evillene, the Wicked Witch Of The West.

434[[folder:Video Games]]
435* ''VideoGame/AliceInTheMirrorsOfAlbion'', which is set in the FairyTaleFreeForAll city of Albion, has the ''Literature/LittleRedRidingHood'' appear as [[Literature/AliceInWonderland the Mad Hatter]]'s niece.
436* In ''VideoGame/CapsuleServant'', Master Artoria has Lancelot and Bedivere as brothers in addition to her actual brother Kay. Downplayed with Gawain and Mordred, who are still related to her but as respectively her father[[note]]rather than nephew[[/note]] and cousin.[[note]]rather than child[[/note]]
437* ''VideoGame/CastlevaniaDraculaX'', a [[ReformulatedGame remixed]] and {{pragmatic|Adaptation}} port of ''VideoGame/CastlevaniaRondoOfBlood'' for the SNES, made Annette and Maria siblings whereas they were unrelated in ''Rondo'' proper. The original English localization of ''[[VideoGame/CastlevaniaSymphonyOfTheNight Symphony of the Night]]'' actually kept this change in, leading many to continue to believe they're sisters even after the matter was officially cleared up.
438* ''VideoGame/FateGrandOrder'':
439** Though they lived centuries apart in their original lives, Arjuna and Minamoto no Raikou are half siblings. Arjuna's father is the Hindu God Indra and Raikou's father is the Shinto God Gozu Tennō, but in the Nasuverse, the two gods are one and the same.
440** It is revealed that Morgan Le Fay and the Lady of the Lake are split personalities of each other. This means the Lady of the Lake's adopted son, Lancelot, is the adopted sibling of Morgan's children Agravain, Gawain, Gaharis, Gareth, and Mordred.
441* Zig-zagged with ''VideoGame/HarvestMoon''. The transition of ''VideoGame/HarvestMoon64'' to ''VideoGame/HarvestMoonBackToNature'' changed a large portion of the characters' relationship with one another.
442** Karen used to be Sasha's and Gotz's daughter; however, in ''Back To Nature'' her father became Jeff, who was originally Elli's father figure (and [[WifeHusbandry love interest]]). Gotz is now a widower.
443** Stu is Elli's little brother in ''Back To Nature''. Originally he was unrelated.
444** Rick was originally Gray's and Ann's cousin. In ''Back To Nature'' he is Popuri's older brother instead, despite still looking related to Ann (they're redheaded while Popuri has pink hair).
445* In the original ''VideoGame/MetalGear'' games for the [=MSX2=], Big Boss was simply Solid Snake's commanding officer who ends up becoming his nemesis. When the franchise was later revived with ''VideoGame/MetalGearSolid'', Solid Snake was revealed to be Big Boss's son, or more specifically a genetically modified clone of him, with one CODEC conversation implying that Big Boss imparted that knowledge to Snake during the events of ''VideoGame/MetalGear2SolidSnake'', even though no such scene actually occurs in that game. This eventually allowed a younger version of Big Boss to be introduced in the prequel ''VideoGame/{{Metal Gear Solid 3|SnakeEater}}'', where he goes under the codename [[LegacyCharacter Naked Snake]].
446* The ''Hēibái Wúcháng'' in Taoist mythos are not related, but Kuromujō and Shiromujō in ''VideoGame/{{Onmyoji|2016}}'' are actual siblings.
447* ''VideoGame/PokemonGoldAndSilver'':
448** No relationship between Silver and Giovanni was ever specified in the original games. In the remakes, as per ''Manga/PokemonAdventures'', Silver is Giovanni's son, and the way Silver is treated (as seen in Celebi's DLC event) is the reason he wants to wipe out Team Rocket itself.
449** While Clair and Lance were originally unrelated, ''[[UpdatedRerelease Pokémon Crystal]]'' obliquely implies that they are -- the guard stationed at the entrance of the Dragon's Den explicitly declares that the master is Clair's grandfather, while one of the master's attendants implies that Lance has a StrongFamilyResemblance to the master. ''Manga/PokemonAdventures'' and ''[[VideoGameRemake Pokémon HeartGold and SoulSilver]]'' would make their relationship as cousins explicit.
450* In ''VideoGame/{{The Punisher|THQ}}'', Jigsaw turns out to be the son of Howard Saint, the BigBad of [[Film/ThePunisher2004 the 2004 live-action movie]].
451* [[VideoGame/SpiderMan3 The tie-in game for]] ''Film/SpiderMan3'' made ComicBook/{{Morbius}} and Shriek husband and wife--despite their comics counterparts being enemies in ''ComicBook/MaximumCarnage'', where the latter also had the hots for the titular ComicBook/{{Carnage}}.
452* In ''VideoGame/XMenOriginsWolverine'', John Wraith is heavily implied to be ComicBook/{{Nightcrawler}}'s father. This actually lines up rather nicely, indicating Nightcrawler got his teleportation powers from Wraith and his blue skin from ComicBook/{{Mystique}}, who was Wraith's lover in this continuity.
453[[/folder]]
454
455[[folder:Web Animation]]
456* ''WebAnimation/KnightsOfTheOldRepublicCinematicUniverse'': Visquis and Saquesh, the two Quarren crime lords based on Nar Shaddaa, are brothers in this universe, whereas they weren't stated to be related in the [[VideoGame/KnightsOfTheOldRepublicIITheSithLords source material]]. After Hanharr kills Saquesh and lies to Visquis that Meetra Surik did it, Visquis gets [[YouKilledMyFather a more personal reason to capture the Jedi Exile]] than he has canonically.
457* In the Myth/RobinHood legends, Guy of Gisbourne is a hitman hired by the Sheriff of Nottingham. In the cyberpunk miniseries ''WebAnimation/Sherwood2019'', Lord Nottingham and Gisbourne are father and son.
458[[/folder]]
459
460[[folder:Webcomics]]
461* ''Webcomic/ArthurKingOfTimeAndSpace'':
462** In the modern day setting, Guinevere is the biological mother of both Mordred and Galahad; their respective fathers remain the same. Morgan is Mordred's mom in the space arc, as is common in modern works.
463** Pelleas is related to the Pellinore family, since he fits their FamilyThemeNaming.
464* In the ''ComicBook/{{Batman}}'' comics, Duke Thomas was just a partner of Batman's. In ''Webcomic/BatmanWayneFamilyAdventures'', much like Dick Grayson, Jason Todd, Tim Drake, and Cassandra Cain, Duke is adopted by Bruce.
465* ''Webcomic/DarthsAndDroids'':
466** Rey is [[spoiler: Rey Solo, the daughter of Jim's serial identity-stealing character (the film's Han Solo) and Princess Organa (Leia)]].
467** Kylo Ren is [[spoiler: the son of the ''actual'' Han Solo whose identity Jim's character stole (the film's Greedo)]].
468* ''Webcomic/DumbingOfAge'': Played straight with Clint, when Ruth and Howard's grandfather suddenly turns out to be the Dumbiverse version of [[http://www.shortpacked.com/index.php?id=112 a character]] who appeared in a single ''Shortpacked!'' strip. Of course, in that appearance it's never specifically stated he's ''not'' Ruth's grandfather.
469* ''Webcomic/{{HSETAU}}'': Karkat and Kanaya are brother and sister, and Tavros is Nepeta's nephew.
470* In ''Kid Beowulf'' (an AlternateUniverse retelling of Literature/{{Beowulf}}), Beowulf is related to all three of his adversaries - Grendel is his non-identical twin brother, Grendel's mother is the mother of both of them, and the dragon is his grandfather (as is Hrothgar).
471* ''Webcomic/MoringMarkTOHComics'' takes several cases of characters being AmbiguouslyRelated in ''WesternAnimation/TheOwlHouse'' and makes the relationships more definitive:
472** The two potion track witches from Eda's WholeEpisodeFlashback show up several times in the present day as [[HomosexualReproduction Boscha's mothers]].
473** Vee is adopted by Camila and has several strips devoted to her and Luz's relationship as sisters. In canon, she is shown to still be treated as a member of the family by the time of the epilogue, but her legal status went unspecified.
474* In ''Webcomic/TransformersLegends'', Windblade is the little sister of Nijika, the Zamojin android from the original '80s ''[[WesternAnimation/TheTransformers Transformers]]'' cartoon.
475[[/folder]]
476
477[[folder:Web Videos]]
478* In ''WebVideo/TheAutobiographyOfJaneEyre'', Adele is the biological daughter of Rochester and [[spoiler: his first wife "M.", whose postpartum depression after Adele's birth and resulting self-medication with drugs led to her current status as the MadwomanInTheAttic.]] In [[Literature/JaneEyre the original novel]], Adéle is just Rochester's ward, the abandoned daughter of his ex-mistress Céline Varens (although Céline claimed Rochester was her father, [[MamasBabyPapasMaybe he doesn't think he is]]), and [[spoiler: she has no connection to his mad wife Bertha.]]
479* ''WebVideo/TheLizzieBennetDiaries'' {{inverted|Trope}} this several times:
480** The Bennet family ZigZagged this as the family relationship got shuffled a bit. In [[Literature/PrideAndPrejudice the novel]], there are five Bennet sisters. Here, only the eponymous protagonist, Jane, and Lydia retained their original status as sisters. Mary was only their (paternal) cousin here, while Kitty became [[AdaptationSpeciesChange Lydia's pet cat instead]].
481** Mr. Collins in the novel is a cousin to the Bennet girls who wants [[KissingCousins to marry one of them]] (specifically, Jane first before setting his sights on Lizzie), then ultimately settles for Lizzie's best friend Charlotte Lucas after being rejected. Here, he is not related to the Bennets and he never marries Charlotte (he becomes her boss instead).
482* ''WebVideo/ThePerfectCastlevaniaTimeline'':
483** While [[VideoGame/Castlevania1986 Simon Belmont]]'s father was never identified in the original game timeline, the series hypothesises his father to have been Desmond, the protagonist of ''VideoGame/CastlevaniaOrderOfShadows''.
484** Shanoa's MysteriousPast is never elaborated on in ''VideoGame/CastlevaniaOrderOfEcclesia'', what with her being an AmnesiacHero. ''The Perfect Castlevania Timeline'' reveals in ''Chapter VII: The Heroic Morris Clan'' that she is descended from [[VideoGame/CastlevaniaCurseOfDarkness Hector and Julia]].
485* In "[[https://www.youtube.com/playlist?list=PLdPXC4UCSSwHojxa1avDzmvLN9_lwqDPr What if DC and Marvel Share the Same Cinematic Universe]]", Ego planted a seed on Krypton which, due to the innate power of Kryptonian psychology, became the being known as Doomsday. This would also make it and Peter Quill half-brothers [[PracticallyDifferentGenerations thousands of years apart]].
486[[/folder]]
487
488[[folder:Western Animation]]
489* In ''[[WesternAnimation/AvengersAssemble Avengers: Black Panther's Quest]]'', the Barons Zemo are descended from Morgan le Fey. This is not the case in the original comics.
490* ''Franchise/DuckTales'':
491** In the original [[WesternAnimation/Ducktales1987 1987 series]], Bubba the Caveduck was apparently a random prehistoric duck that ended up [[ContemporaryCaveman coming back to the present]] with Scrooge and the others during a TimeTravel excursion. In the [[WesternAnimation/Ducktales2017 2017 reboot]], it's shown that Bubba is actually a prehistoric ancestor of the [=McDuck=] Family [[spoiler:which regrettably meant that he had to stay in his own time rather than become a series regular]].
492** The reboot's series finale reveals that [[spoiler: Webby Vanderquack is ''also'' a [=McDuck=] -- she's Scrooge's daughter via cloning, created by F.O.W.L. to use against him. By extension, her clones May and June (who are based off two of Daisy's triplet nieces in the comics -- Webby herself is a CompositeCharacter with April, the third triplet) are also Scrooge's daughters.]]
493* ''WesternAnimation/{{Gargoyles}}'':
494** WordOfGod says that the events of ''Theatre/AMidsummerNightsDream'' are at least loosely based on [[TheFairFolk Oberon and Titania]]'s actual past, but that in this version Oberon's interest in the changeling child comes from him being [[HalfHumanHybrid his son with a mortal woman]].
495** WordOfGod says that in this show's version of Arthurian myth, Nimue is Arthur's biological half-sister but was switched for the [[ChangelingTale changeling]] Morgana le Fay.
496* ''WesternAnimation/GIJoeTheMovie'' turned Lt. Falcon into Duke's half-brother. The later ''WesternAnimation/GIJoeRenegades'' series take it a step further by revamping him into Duke's full-blooded brother Vincent Hauser, who is considerably younger in this incarnation (not even old enough to join the military yet).
497* ''WesternAnimation/GuardiansOfTheGalaxy2015'' sees Korath as one of Thanos' "children" and thus is the adopted brother of Gamora and Nebula, whereas even the film suggests Korath is a member of the Kree Empire.
498* ''WesternAnimation/HeManAndTheMastersOfTheUniverse2002'' made Man-At-Arms and Fisto brothers. Also there was some implication (though never confirmed) that either Man-At-Arms or Fisto was Teela's biological father. In the Filmation cartoon Teela was Man-At-Arms' adopted daughter and her biological father was an unnamed soldier who had died years before, while in the original minicomics Teela was a clone of the Sorceress created by Skeletor.
499* ''WesternAnimation/HeManAndTheMastersOfTheUniverse2021'': The season 3 finale reveals [[spoiler: Hordak]] is Evil-Lyn's father. In all previous continuities, they have been unrelated.
500* In ''WesternAnimation/TheIncredibleHulk1996'', Ogress is one of the Gamma Warriors cloned from the Hulk's DNA, in contrast to the comics, where she was simply a lawyer who was mutated by the Leader's gamma bomb.
501* Both inverted and played straight with Madame Masque in ''WesternAnimation/IronManArmoredAdventures'' as she's reimagined as the Iron Monger's daughter, yet her comic book father, Count Nefaria, also appears.
502* ''WesternAnimation/LittleShop'', the AnimatedAdaptation of ''Film/LittleShopOfHorrors'', makes Audrey into Mr. Mushnik's daughter, rather than just his employee.
503* In ''WesternAnimation/MarvelsSpiderMan'', Gwen Stacy turns out to be [[spoiler: the niece of Raymond Warren/The Jackal]].
504* ''WesternAnimation/MyAdventuresWithSuperman'' portrays Silver Banshee and the series' version of Mist as siblings, despite Silver Banshee having never been related to any character who goes by the Mist identity in the comics.
505* ''WesternAnimation/MyLittlePonyFriendshipIsMagic'':
506** In the [[WesternAnimation/MyLittlePonyRescueAtMidnightCastle original TV special]], Scorpan was [[TheDragon Dragon]] to Tirek. In ''Friendship is Magic'', the two are brothers. In both cases, Scorpan pulled a HeelFaceTurn and helped the ponies defeat Tirek.
507** In [[WesternAnimation/MyLittlePonyG3 the franchise's previous incarnation]], Rarity and Sweetie Belle are unrelated. In ''Friendship is Magic'', the two are sisters, with Rarity being the elder of the two.
508* ''WesternAnimation/TheNewAdventuresOfJonnyQuest'' introduced a redheaded young girl named Jessie as a potential new companion for the heroes. The character was revived for ''WesternAnimation/JonnysGoldenQuest'', ''WesternAnimation/JonnyQuestVersusTheCyberInsects'' and ''WesternAnimation/TheRealAdventuresOfJonnyQuest'', where she was reimagined as Race Bannon's daughter.
509* In the 2014 ''WesternAnimation/RainbowBrite'' reboot [[spoiler:Brian]] is a descendant of [[spoiler:Krys]]. In the original continuity they co-exist in the same time period, but never meet each other.
510* ''WesternAnimation/SabrinaSecretsOfATeenageWitch'':
511** Shinji is Enchantra's son.
512** Enchantra and Della ([[AdaptationNameChange renamed Spella]]) are sisters.
513* In the ''Donkey Kong'' segment of ''WesternAnimation/SaturdaySupercade'', Pauline was Mario's niece, rather than girlfriend. (Luigi had not debuted in ''VideoGame/MarioBros'' yet, making this adaptation very HilariousInHindsight.)
514* ''WesternAnimation/SevenLittleMonsters'' establishes that the titular monsters are siblings, when the original book, in spite of depicting the monsters living in the same house, gave no indication whatsoever that they were related.
515* ''WesternAnimation/SheRaAndThePrincessesOfPower'':
516** Adora and Catra are turned into Shadow Weaver's adopted daughters.
517** Castaspella is turned into King Micah's sister, making her Queen Angella's sister-in-law and Glimmer's aunt. This entails Castaspella getting a RaceLift, since this version of Micah is Asian.
518* ''WesternAnimation/SkylandersAcademy'':
519** Cynder is the daughter of Malefor.
520** At the end of the show, [[spoiler:[[BigGood Master Eon]] reveals to [[BigBad Kaos]] and the audience that he is the latter's father. And since Eon also adopted Spyro when he was an orphan, this makes Spyro and Kaos adoptive brothers.]]
521* ''WesternAnimation/TheSpectacularSpiderMan'':
522** In the ''ComicBook/SpiderMan'' comics ComicBook/SilverSable and Silvermane are a completely unrelated mercenary and gangster. In ''The Spectacular Spider-Man'' Silver Sable is Silvermane's villainous daughter. Thus her [[AdaptationNameChange real name was changed]] from [[PropheticNames Silver Sablivona]] to Sable Manfredi.
523** The series also combines this trope with CompositeCharacter. In the comics Uncle Ben's killer is a nameless street thug. In the cartoon, he's [[spoiler:ComicBook/BlackCat's]] father [[spoiler:The Cat]].
524** In the comics, Liz Allan has a step-brother named Mark Raxon with whom she's very close; in this series they're blood siblings with the surname Allan.
525* ''WesternAnimation/SpiderMan1967'' had Mary Jane Watson as the niece of [[TheCommissionerGordon Captain Stacy]], to whom she was unrelated in the comics. This let her [[CompositeCharacter carry some of the role of Gwen Stacy]], Spidey's other major love interest in the comics, who wasn't used in the series.
526* ''WesternAnimation/SpiderManTheAnimatedSeries'' sees the ComicBook/RedSkull as the father of Electro and the Chameleon (the former being Electro in-name and costume only, the latter was adopted). Also inverted with the latter as the Chameleon isn't the half-brother of Kraven.
527* ''Franchise/TeenageMutantNinjaTurtles'': Karai in the original Mirage comics was simply Shredder's top agent. In the [[WesternAnimation/TeenageMutantNinjaTurtles2003 2003 cartoon]], she is his adopted daughter. In the [[WesternAnimation/TeenageMutantNinjaTurtles2012 2012 cartoon]], she appears to be Shredder's biological daughter, but it's later revealed he kidnapped her in infancy and raised her, but she's actually Splinter's biological daughter (making her the turtles 'step'-sister.) In ''WesternAnimation/RiseOfTheTeenageMutantNinjaTurtles'', Karai is Splinter's distant ancestor and founder of the Hamato clan. [[spoiler:This is in ''addition'' to being the Shredder/Oroku Saki's biological daughter (making Splinter and Shredder related as well).]]
528* ''WesternAnimation/TeenTitansGo'': The ComicBook/DoomPatrol are introduced in the sixth season, with the show's interpretations of Robotman and Negative Man (or rather, [[GenderFlip Negative Girl]]) being Beast Boy's adoptive siblings (which by extension makes Elasti-Girl their adoptive mother as well as Beast Boy's) and the Chief [[CompositeCharacter taking Mento's place as Beast Boy's adoptive father]].
529* In the original ''WesternAnimation/TinyToonAdventures'', one of the major {{running gag}}s for the show was Buster and Babs Bunny clarifying that they weren't related when they introduced themselves. In the ''[[WesternAnimation/TinyToonsLooniversity Looniversity]]'' reboot, however, they're [[HalfIdenticalTwins fraternal twins]].
530* ''WesternAnimation/TotalDramaRama'': In the episode "Dissing Cousins", ''WesternAnimation/TotalDrama Pahkitew Island'' competitors [[HarmlessVillain Max]] and [[PrincessPhase Ella]] are written in the series as the respective cousins of ''Total Drama Island'' contestants [[BigFun Owen]] and [[PerkyGoth Gwen]], despite having never interacted with them in the original series.
531* In the British television series, ''WesternAnimation/{{TUGS}}'', Ten Cents and Sunshine were best friends, and were both male. In the American translation, ''WesternAnimation/SaltysLighthouse'', Sunshine [[ShesAManInJapan became female]] and Ten Cents' younger sister.
532* In ''WesternAnimation/VoltronLegendaryDefender'', Haggar is Zarkon's wife and Lotor's mother. This serves as a MythologyGag as Haggar's ''Anime/{{Golion}}'' counterpart is Zarkon's counterpart Daibazaal's mother.
533* ''WesternAnimation/WackyRaces2017'' established that the Gruesome Twosome are brothers, when [[WesternAnimation/WackyRaces the original cartoon]] never indicated that they were related.
534* ''WesternAnimation/XMenEvolution'': Xavier and Juggernaut are changed from step-brothers to half-brothers.
535* ''WesternAnimation/YoungJustice2010'':
536** Cheshire becomes the sister of Artemis, and therefore the daughter of the original Huntress and Sportsmaster. This entails Artemis and Huntress getting a RaceLift.
537** ComicBook/MartianManhunter and Miss Martian are uncle and niece, while they're unrelated in the comics. WordOfGod confirms that this is true, despite the revelation that [[spoiler:M'gann is actually a White Martian]], later, [[spoiler:Ma'alefa'ak also is changed from Martian Manhunter's brother to Miss Martian's]].
538** Lynn Stewart, ComicBook/BlackLightning’s ex-wife, is also the sister of John Stewart, the ComicBook/GreenLantern.[[note]]Her name being Stewart was intentional on the part of her creator, Tony Isabella. He didn’t make her John’s sister but decided to leave the door open if someone else wanted to do it. This just happens to be the first time someone took the opening.[[/note]]
539** [[ComicBook/DoctorFate Nabu]] was one of [[Characters/DCComicsVandalSavage Vandal Savage]]'s countless children. Season 4 subsequently reveals that the Atlantean sorcerer Arion was also Savage's grandson.
540** PlayedWith: In the comics, Halo's real name was Violet Harper, but she had no connection to [[ComicBook/GreenArrow Roy Harper]]. Here, Halo uses a pseudonym, and Roy casually offers his surname when she can't come up with one. Similarly, in the comics, Guardian's real name is Jim Harper. In the show he's a Roy's "uncle", who is actually his clone artificially aged to adulthood.
541** Baron Bedlam is now the Markov children's EvilUncle.
542** Onyx is the granddaughter of Will Everett, the ComicBook/AllStarSquadron member Amazing-Man.
