History ThickerThanWater / FanWorks

* In ''[[https://www.fanfiction.net/s/9928169/8/Panzer-und-uni Panzer und uni]]'', even though Isla Sato is an extreme {{Jerkass}}, an incompetent commander, a bully toward those she doesn't like, and responsible for [[MoralEventHorizon shooting at an enemy flag tank while its commander is rescuing a member of Sato's team, thereby endangering rescuer and rescued]], her younger sister Megan still cares for her. When Isla's actions catch up to her and she gets kicked off the team, expelled and disowned, Megan asks Miho to serve as a reference for Isla so she can get a job more easily- Miho accepts, knowing she'd do the same for her own sister, Maho.

** Orion is probably the most extreme example of this. He is so loyal to his family that he seems to make it his life purpose to uphold the honour of its name and its legacy, and will always defend his relatives whenever someone (usually Sirius) badmouths them. However, it's obvious that he's not particularly fond of most of them either, barring his sister, wife and children -- and he prefers to seclude himself in his study than deal with their antics whenever there is a family gathering.

* In Fanfic/RainbowDoubleDashsLunaverse, Night Light refuses to believe that Twilight could have done anything wrong. He sees his daughter's [[spoiler: fugitive status]] as being entirely Trixie's fault -- it's actually both of theirs -- and is entirely willing to [[DisproportionateRetribution let Ponyville remain in ruins to get back at the latter.]] ''At the Grand Galloping Gala'', [[spoiler:Ditzy]] calls him out on it by using her own motherhood to give herself the high ground and deflect his attempts to use this.
* In ''FanFic/TheMasksWeWear'', Zuko refuses to betray his father despite the fact that he (Ozai) burned him.

* Defied epically by Corrin in Fanfic/ABrighterDark.

* Averted in ''[[http://archiveofourown.org/series/712947 Laurel Lance Character Studies]]'', where Thea displays more loyalty to Laurel than to her brother Oliver. To the point that she outright states Laurel deserves better than him; and after (repeatedly) begging Laurel to "scream about what an ass my brother is" Laurel's confessions/rants make Thea angry enough to avoid Oliver ''for days''. Although a case could be made that she ''is'' choosing family, it just isn't her blood.
* Subverted in ''Fanfic/NeitherABirdNorAPlaneItsDeku''. Even after learning about the wonders of Krypton and his biological father's efforts to save him from his planet's destruction, Izuku can't help but feel a stronger connection to his adoptive parents than his birth parents. As far as he's concerned, the Midoriyas are his real parents.
-->'''Izuku:''' I-I mean, my mom and dad didn't make me, but they're the ones who raised me. They're the ones who taught me right from wrong. They're the ones who always tried to make me feel okay with being, well, me. Jor-El and Lara Lor-Van gave me life, but as far as I'm concerned, Inko and Hisashi Midoriya are my real parents.
* Discussed and subverted in ''Fanfic/OnlyFlowersFall''. Lillie disowns her previously abusive mother but others, including her brother Gladion, tell her she should forgive her because they're blood. Even Lillie is confused on what she should do until her maternal figure Professor Burnet explains that she shouldn't forgive Lusamine just because they're related.
-->''You’re being cruel, they say. She’s your mother, and you’re her child. You need to reconcile someday, so why are you holding back? She told you that she’s sorry. What more do you want?\\
(You want your childhood back.)''

* ''Fanfic/TheBridge'': Defied with the Godzilla Junior, who was adopted and raised by a human mother he imprinted on and then Godzilla Senior, who had no genetic tie to him outside of being the same species. The assumption he yearns to find his birth parents to find out why his egg was abandoned so he can know his "real family" is brought up a few times and shredded. He holds no ill will to his biological parents, but is entirely apathetic to finding them or seeing if they are still alive. To him, Azusa and Senior are and were his "real parents".
* This is one of the main themes of ''Fanfic/TheBlackSheepDogSeries''.
** Sirius is told by his CoolUncle Alphard that no matter how much he hates his family and try to deny their blood ties, he can never change the fact that he is a Black. Indeed, despite having run away, Sirius is still living off on his family's wealth (i.e. the inheritance he got from Alphard), and the readers see that, despite his defiance, he is still very much no different from the rest of his clan. He also gets surprisingly defensive when Frank accuses his parents as being Death Eaters.
** Alphard himself couldn't help but miss his ancestral home whenever he's away despite not being able to stand most of his kin and goes through great lengths to avoid interacting too much them whenever he does come to visit. He muses that this sentimentality must be caused by the "siren song of [his] blood".

--->''"They may be a -- difficult bunch -- but they are my family. If I don't defend them, no one else will."''

All of his mutually acknowledged family like Biollante and Xenilla are also adoptive.
