** In the Walkyverse, Faz turned out to be Amber's half-brother, conceived from her dad's extramarital affair. In ''Dumbing of Age,'' Faz is apparently her stepbrother instead.

* ''Anime/DemashitaPowerpuffGirlsZ'': None of ''WesternAnimation/ThePowerpuffGirls'' are related. Professor Utonium also isn't their father, instead having his own son.

* In ''Manga/Naruto1997'' Naruto is the son of the Nine-Tailed Fox. In ''Manga/{{Naruto}}'' the Nine-Tailed Fox is simply sealed inside of Naruto.

* ''Film/BAtmanAndRobin'' sees Batgirl as Alfred's niece instead of Commissioner Gordon's daughter.

** In ''ComicBook/TheMightyThor'', ComicBook/LadySif and Heimdall are siblings, but there's no sign of that in the movies.

** A variation with 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|MarvelComics}}, who is the comic universe's lost sister]]. Also inverted with Fenris. In the comics, he's Loki's son and Hela's brother. Here, [[GenderFlip she]] is simply Hela's servant.

* In both the ''ComicBook/MarvelComics2'' universe and ''Franchise/MarvelCinematicUniverse, Hope Pym is the biological daughter of Janet van Dyne, [[ComicBook/TheWasp the original Wasp]]. While still the bilogical daughter of [[ComicBook/AntMan Hank Pym]], [[ComicBook/UnstoppableWasp Nadia Pym]]'s biological mother is Hank's first wife, Maria Trovaya, with Janet as her surrogate mother.

* In both the ''ComicBook/MarvelComics2'' universe and ''Franchise/MarvelCinematicUniverse, Hope Pym is the biological daughter of Janet van Dyne, [[ComicBook/TheWasp the original Wasp]]. [[ComicBook/UnstoppableWasp Nadia Pym]], while still the daughter of [[ComicBook/AntMam Hank Pym]], her biological mother is Hank's first wife, Maria Trovaya, with Janet as her surrogate mother.

** A combination of this and RelatedInTheAdaptation, but Star-Lord/Peter Quill is normally the son of J-Sonn of Spartax. Here, they are unrelated (and J-Sonn is only vaguely alluded to at most), and is instead the child of Ego the Living Planet, when in the comic, they are unrelated.

** The Ravager. She's usually the illegitimate daughter of [[ComicBook/{{Deathstroke}} Slade Wilson]]. Here, she's merely his [[TheDragon Dragon]]. Justified though, as she's a CompositeCharacter of Isabel Rochev, who's the Ravager's actual civilian identity in this version.
** Jean Loring and [[ComicBook/TheAtom Ray Palmer]] are a married couple in the comics. In the show, she's given an AgeLift and is now old enough to be his mother while Ray mentions a dead fiancee. ''Legends'' reveals that Ray's aforementioned late fiancee was named Ana Loring, making her and Jean a DecompositeCharacter.

*** The Ravager. She's usually the illegitimate daughter of [[ComicBook/{{Deathstroke}} Slade Wilson]]. Here, she's merely his [[TheDragon Dragon]]. Justified though, as she's a CompositeCharacter of Isabel Rochev, who's the Ravager's actual civilian identity in this version.
*** Black Canary III, who is initially introduced as Tina Bolland before [[CanonCharacterAllAlong her real name]] is [[spoiler: Dinah Drake; which is the name of comic book Dinah Laurel Lance's mother]]. Of course, the three Canaries of the show are a strange mix of CompositeCharacter and DecompositeCharacter to the two of the comics, making it hard to tie down which one directly adds up to which other.

*** Eddie Thawne, when compared to his closest comic counterpart Malcolm Thawne: in addition to being [[AdaptationalHeroism a much nicer person]], Eddie has no blood relation to Barry Allen, whereas Malcolm was Barry's identical EvilTwin, which along with ComicBook/{{Impulse}}, gives Barry familiar ties to his arch-foe, Eobard Thawne/Reverse-Flash. [[spoiler: However, while he's not a blood relative of Barry's, Eddie is still an ancestor to Eobard.]]

** ''Series/LegendsOfTomorrow'': In the comics, Connor Hawke is Oliver's bastard son and successor as Green Arrow. Here, he's merely someone inspired to take up Oliver's superhero mantle. This is a result of him being turned into a DecompositeCharacter, as his original status as Oliver's illegitimate son was given to William Clayton in the show. [[spoiler: Instead, he's John Diggle's son. If that's the case, then he is also RelatedInTheAdaptation to Lyla Michaels, Harbringer from the comics, who is John Diggle's wife.]]

** In ''[[Series/PowerRangersLightspeedRescue Lightspeed Rescue]]'' and ''[[Series/PowerRangersMysticForce Mystic Force]]''; their ''Sentai'' counterparts ''[=GoGoV=]'' and ''[[Series/MahouSentaiMagiranger Magiranger]]'' were {{Super Family Team}}s composed of siblings, but none of the core ''Lightspeed'' Rangers were related[[note]]''Lightspeed''[='s=] Pink and Titanium Rangers were siblings, but Titanium was a CanonForeigner that didn't exist in ''Sentai''[[/note]] and family relations of the Mystic Rangers were drastically reduced: the Blue and Pink Rangers were sisters, and only the Red Ranger was related to supporting characters instead of the entire team.

** Happens again with ''ComicBook/{{Nightcrawler}}''. The movies give no indication that ''ComicBook/{{Mystique}}'' and Azazel are his parents like they are in the comics. Though the only "hint" of possible relations between Nightcrawler and Mystique is a scene in ''X2''.

* ''ComicBook/UltimateSpiderMan'': Ben Reilly, who is Peter's clone in the main comics (sometimes referred to as his "brother" or [[UncannyFamilyResemblance identical cousin]]), is an unrelated lab assistant in the Ultimate verse.

* In ''WesternAnimation/VoltronLegendaryDefender'', [[spoiler: Romelle and Allura are unrelated, as Romelle was born in a secret Altean colony millennia after Allura went into stasis. This contrasts their relationship in the original ''Anime/{{Voltron}}'' show, where they are cousins]].

* ''Film/{{Banlieue 13}}'' has Lola being changed from Leito's sister in the original to his ex-girlfriend in the remake ''Film/BrickMansions''.
* In the Franchise/MarvelCinematicUniverse:

** A variation with 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).

In the comics, he's Loki's son and Hela's brother. Here, he's simply Hela's servant.

* ''[[Film/GIJoeTheRiseOfCobra G. I. Joe]]'' shows no sign that Heavy Duty and Roadblock are cousins.
* ''Film/JemAndTheHolograms'' has thiswith Shana and Aja. They're Kimber and Jerica's foster sisters in the cartoon however here they are barely acquainted. They're still their foster siblings but the close bond between them from childhood is lost.
* ''Film/FantasticFour2015'': rather than have Susan and Johnny Storm be blood siblings, Susan was adopted into the Storm family. This was done so they could give Johnny a RaceLift to increase the team's diversity without having to do the same to Sue.

* ''Series/{{Arrow}}'':
** The Ravager. She's usually the illegitimate daughter of [[ComicBook/{{Deathstroke}} Slade Wilson]]. Here, she's merely his [[TheDragon Dragon]]. Justified though, as she's a CompositeCharacter of Isabel Rochev, whom the Ravager's actual civilian identity in this version.
** Black Canary III, who is initially introduced as Tina Bolland before [[CanonCharacterAllAlong her real name]] is [[spoiler: Dinah Drake; which is the name of comic book Dinah Laurel Lance's mother]]. Of course, the three Canaries of the show are a strange mix of CompositeCharacter and DecompositeCharacter to the two of the comics, making it hard to tie down which one directly adds up to which other.
* ''Series/TheFlash2014'':
** Eddie Thawne, when compared to his closest comic counterpart Malcolm Thawne: in addition to being [[AdaptationalHeroism a much nicer person]], Eddie has no blood relation to Barry Allen, whereas Malcolm was Barry's identical EvilTwin, which along with ComicBook/{{Impulse}}, gives Barry familiar ties to his arch-foe, Eobard Thawne/Reverse-Flash. [[spoiler: However, while he's not a blood relative of Barry's, Eddie is still an ancestor to Eobard.]]
** 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]]
* ''Series/LegendsOfTomorrow'': In the comics, Connor Hawke is Oliver's bastard son and successor as Green Arrow. Here, he's merely someone inspired to take up Oliver's superhero mantle.

* Romelle is Allura's cousin in the original ''Anime/{{Voltron}}'' show. In ''WesternAnimation/VoltronLegendaryDefender'', the two are unrelated, [[spoiler:as Romelle was born in a secret Altean colony millennia after Allura went into stasis.]]

* ''Film/XMen''

* ''Series/{{Arrow}}''

* ''Series/TheFlash2014''

* Played straight ''and'' inverted at the same time with the New Enchanted Forest version of [[Disney/{{Cinderella}} the Tremaine family]] in ''Series/OnceUponATime''. The "wicked stepmother" (in addition to being [[spoiler: 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.

* ''Franchise/MyLittlePony'': In the [[WesternAnimation/MyLittlePonyG3 third generation cartoons]] that aired around the TurnOfTheMillennium, the characters Cheerilee and Scootaloo were sisters. In ''WesternAnimation/MyLittlePonyFriendshipIsMagic'', which premiered in late 2010 after the close of G3, Cheerilee is simply the town schoolteacher and has no relations to Scootaloo, reassigned as a young filly, beyond the typical teacher-student relationship she has with all her other students.

* Played straight with Heavy Duty and Roadblock in ''[[Film/GIJoeTheRiseOfCobra G. I. Joe]]'', as there aren't any hints of them being cousins.

* In ''Series/LegendsOfTomorrow'', Connor Hawke. In the comics, he's Oliver's bastard son and successor as Green Arrow. Here, he's merely someone inspired to take up Oliver's superhero mantle. This is a result of him being turned into a DecompositeCharacter, as his original status as Oliver's illegitimate son was given to William Clayton in the show. [[spoiler: Instead, he's John Diggle's son. If that's the case, then this plays straight with Lyla Michaels, Harbringer from the comics, who is John Diggle's wife.]]

* In the ''ComicBook/New52'', Billy and his ''ComicBook/{{Flashpoint}}'' friends are now foster-siblings. Played straight, however, in that he and Mary, former [[LongLostRelative long-lost twins]], no longer seem biologically related. (Also, she seems to be older than him.)
* ''ComicBook/TeenTitansEarthOne'': Played straight when [[spoiler:both Elinore Stone and Slade Wilson who are no longer biologically related to the children that they each raised, [[Comicbook/{{Cyborg}} Victor Stone]] and Joseph Wilson respectively]].

* ''Manga/MagicalGirlLyricalNanohaINNOCENT'': Happens with Fate, who was never adopted into the Harlaown family due to Precia being alive and sane in this continuity. Of course, it's downplayed due to [[HeterosexualLifePartners Precia and Lindy]] raising their children side by side.

* Played straight with ''Literature/{{Babar}}''. In the books Babar married [[KissingCousins his cousin]] but in the animated adaptations he marries a [[ChildhoodFriendRomance childhood friend]].

* ''WesternAnimation/VoltronLegendaryDefender'': [[spoiler: Romelle is Allura's cousin in the original ''Anime/{{Voltron}}'' show. Here, the two are unrelated, with Allura being about 10,000 years older.]]

* In the ''ComicBook/New52'', Billy and his ''ComicBook/{{Flashpoint}}'' friends are now foster-siblings. {{Inverted}}, however, in that he and Mary, former [[LongLostRelative long-lost twins]], no longer seem biologically related. (Also, she seems to be older than him.)
