History HappilyAdopted / FanWorks

*** [[WesternAnimation/DannyPhantom Danny]] getting his family to adopt Dani after she becomes a looper.
*** [[Franchise/{{Kirby}} Meta Knight]] adopting both [[WesternAnimation/TotalDrama Duncan]] and [[VideoGame/PaperMarioTheThousandYearDoor Vivian]].

* In ''Fanfic/HarryPotterAndTheIcePrincess'', while [[spoiler:Harry isn't officially adopted by Elsa's parents, they make him a ward of Arendelle when he comes to visit the summer before third year, granting him similar protection to the spells that kept him safe at the Dursleys so long as the trolls perform appropriate rituals]].

** Happens on occasion, both on a temporary basis (variant loops with adoption) or on a permanent basis (one looper adopting another).

* The ''Series/BuffyTheVampireSlayer''/''Series/{{Angel}}'' fic "[[https://www.fanfiction.net/s/6354962/1/All-Through-the-Night All Through the Night]]" depicts Wesley succeeding in his plan to abduct the infant Connor, as he then took him to Sunnydale for safety, even providing paperwork so that Buffy can register herself as Connor's mother.

** ''Fanfic/TheMLPLoops'': Considering Equestria is built on ThePowerOfFriendship, it shouldn't be surprising that this happens pretty often.
*** When Fluttershy first looped into ''TabletopGame/{{Warhammer 40000}}'', she found an infant in a stasis pod and raised him as her son. This turned out to be Leman Russ, Primarch of the Space Wolves. He proudly refers to Fluttershy as "Little Mother," and it was her influence that kept him sane enough that he became an Anchor and started his entire universe looping. Because of the quasi-logic of variant loops, it's not uncommon for them to find themselves in a loop where they are biological mother and son. But even when they're not, he still treats her as his mother.

* ''Fanfic/HalfPastAdventure'': Despite a bit of GeneHunting in the first chapter, Macy overall seems extremely happy with her adopted family.

* In ''[[https://www.fanfiction.net/s/1607730/1/Know-Thyself-the-Prelude Know Thyself- the Prelude]]'', Franchise/HarryPotter is unplugged from Franchise/TheMatrix and is swiftly adopted by the crew of the ''Nebuchadnezzar'', with Trinity and Neo as his parents while Tank and Morpheus are the fun uncle and strict grandfather respectively (although Harry is 'officially' down as Morpheus's apprentice for the purpose of justifying his presence on the crew).

* ''Fanfic/ItsNotTheRaptorDNA'': Rexy, the TyrannosaurusRex from ''Film/JurassicPark'' takes Elise under her wing after [[MamaBear saving her from a prion-infected Triceratops]].

* In ''[[https://www.fanfiction.net/s/1826305/1/The-Key-To-Marauding The Key to Marauding]]'', when Dawn Summers finds herself in Hogwarts during the Marauders' era, [[spoiler:once she decides to remain in her new world even after Buffy and the others find her]], she is adopted by James's parents, to the extent that she is down on some Ministry paperwork as 'Dawn Summers-Potter' up to the time of ''Literature/HarryPotterAndTheOrderOfThePhoenix''.
* The ''Series/StargateSG1'' fanfic ''[[https://www.fanfiction.net/s/3070319/39/Bless-the-Children-Gen-Version Bless the Children]]'' has an interesting twist of this concept, as Daniel Jackson ends up adopting a clone of himself created by an alien culture who unintentionally gave the clone the memory of the traumatic death of Daniel's parents when he was eight years old. Even before he learned that Daniel was technically him, 'Danny' referred to Daniel as 'Daddy' after a violent nightmare and came to consider him and the rest of SG-1 family, with the [[https://www.fanfiction.net/s/3070316/47/Bless-the-Children-Ship-Version 'Ship version]] of this story adding to this dynamic when Daniel and Samantha Carter develop feelings for each other. Having learned of his identity and connection to Daniel, Danny actually encouraged him and Sam to get together because he wants them to be happy, [[spoiler:which culminates in Daniel and Sam getting married and Sam learning that she's pregnant, with Danny shown to be very excited at the idea of being a big brother]].

* ''Fanfic/WinterInLifsHolt'' sees Hiccup and Astrid adopt Astrid’s niece, Ætta, after the deaths of Ætta's parents; her father (Astrid's older brother) was lost at sea and her mother died of an illness. The girl is soon freely invited to call Stoick 'Granpa Stoick' and [[spoiler:even unofficially claims one of Toothless's hatchlings as her future dragon]].

* In ''WesternAnimation/DannyPhantom'' fanfic ''Fanfic/{{ResurrectedMemories}}'': The Fentons have adopted [[OppositeSexClone Dani]] into the family after the Disasteroid incident.

* The ''Literature/{{Twilight}}'' fic ''[[https://www.fanfiction.net/s/8146758/1/Roses-in-Winter Roses in Winter]]'' has Angela Weber swiftly taken in by the Cullens after her biological parents are presented as incompetent at best and explicitly abusive at worst. Not only does Emmett freely refer to himself as Angela's big brother, but shortly after Angela learns the truth about the Cullens, while she's falling asleep, she mentions that she'd give anything for Esme to be her mother. The bond becomes so deep that even ''the Volturi'' recognise that Angela's compassion makes her so like Carlisle she might as well be his biological daughter.

* In the later installments of ''Fanfic/SkyholdAcademyYearbook'', [[VideoGame/DragonAgeInquisition Cassandra Pentaghast]] and her husband are the parents of an adopted baby boy.

* The Project Motherhood series by Gamer95 on Fanfiction.Net runs almost entirely on this trope, having female or sometimes genderswapped versions of fictional characters rescuing Harry Potter [Sometimes Crona from Soul Eater or Isaac from The Binding of Isaac] from an intensely abusive living condition and raising them as their own child.

* ''Fanfic/HalfPastAdventure'': Despite a bit of GeneHunting in the first chapter, Macy overall seems extremely happy with her adopted family.

** Averted with the [[spoiler: Founding Father of the Purifiers. ]]Like Itzak, he was found after his family was slaughtered in ethnic cleansing during the Global Civil War. However, the family that adopted him subjected him to horrific abuse. [[spoiler: His ethnic cleansing campaign forty to fifty years later was as much revenge against those who shared the blood of his adoptive family as it was to obtain more ''Lebensbraum'' for his followers.]]

* ''[[https://www.fanfiction.net/s/11178093/1/My-Simpsons-Guy-Story My Simpsons Guy Story]]'' sees Meg Griffin essentially adopted by the Simpsons after she spends a summer in Springfield as a child as part of a student exchange program. When they reunite with Meg in her teens, Meg falls in love with Bart, with Homer and Marge being far more supportive parents to her than Peter and Lois.

* ''Fanfic/BloodThatFlows'': Momoko Takamachi [[spoiler:(aka, Lina Inverse)]] adopts Fate Testarossa instead of Lindy, making Fate and Nanoha sisters. Both are quiet pleased by the arrangement. Years later, [[spoiler:Yuuno and Arisa do this for Caro]].

* In ''Fanfic/AvengersInfiniteWars'', when the Avengers express their discomfort about the Jedi Order basically taking infants from their families to train them as Jedi, after a mission leads to the Avengers rescuing FOrce-sensitive infants from Seperatist bounty hunters, Obi-Wan in particular recommends that the Council allow the Avengers to retain custody of the orphans to give them a better understanding of the Order. As a result, the Avengers become the guardians of the Force-sensitive infants Mara Jade and 'Baby Yoda'.

* ''[[https://www.fanfiction.net/s/3070319/39/Bless-the-Children-Gen-Version Bless the Children]]'' has an interesting twist of this concept, as Daniel Jackson ends up adopting a clone of himself created by an alien culture who unintentionally gave the clone the memory of the traumatic death of Daniel's parents when he was eight years old. Even before he learned that Daniel was technically him, 'Danny' referred to Daniel as 'Daddy' after a violent nightmare and came to consider him and the rest of SG-1 family, with the [[https://www.fanfiction.net/s/3070316/47/Bless-the-Children-Ship-Version 'Ship version]] of this story adding to this dynamic when Daniel and Samantha Carter develop feelings for each other. Having learned of his identity and connection to Daniel, Danny actually encouraged him and Sam to get together because he wants them to be happy, [[spoiler:which culminates in Daniel and Sam getting married and Sam learning that she's pregnant, with Danny shown to be very excited at the idea of being a big brother]].
** On a wider note, Danny also refers to Jack O'Neill as 'Uncle Jack', and is told that he can consider General Hammond and Catherine Langford his new grandparents.

* ''[[https://www.fanfiction.net/s/11178093/1/My-Simpsons-Guy-Story My Simpsons Guy Story]]'' sees Meg Griffin essentially adopted by the Simpsons after she spends a summer in Springfield as a child; when they reunite in her teens, Meg falls in love with Bart, with Homer and Marge being far more supportive parents to her than Peter and Lois.
