History ParentalSubstitute / FanWorks

** Princess Celestia and Princess Luna were raised by the Equestrian Founders, seeing Starswirl the Bearded especially as a father figure. Part of the reason Luna grew jealous of Celestia and turned into Nightmare Moon was she felt, incorrectly, that she was the UnFavorite in Starswirl's eyes.

* ''Fanfic/ACrownOfStars'' (''Anime/NeonGenesisEvangelion'' and other): Misato was Shinji and Asuka's guardian and caretaker during the Angel War, at the end of the which she got killed. During the story Daniel brought her back, and she dedicated herself to fight to rebuild the post-Third Impact world as a way to atone for neglecting her wards during the War.

After their explanations Misato agrees to be Rei's guardian, too.
* ''Manga/Evangelion303'' (''Anime/NeonGenesisEvangelion''): Ritsuko took care of Shinji for a short while when his father sent him away after his mother's death.

When they summoned him back, Misato became his guardian. She also became Asuka's caretaker when the Sohryu family arrived on Tokyo-3. After considering she had ruined her daughter's life utterly Kyoko thought it would be for the best if Misato adopted Asuka, but Misato talked her out of it.
* ''Fanfic/OnceMoreWithFeeling'' (''Anime/NeonGenesisEvangelion''):

* ''Fanfic/TheOneILoveIs'' (''Anime/NeonGenesisEvangelion''): Misato took Shinji and Asuka in when they were summoned to Tokyo-3. Shinji also looks up to Kaji and often goes to him for help, advice or counseling. Several times He has wished that Kaji was his real father.

--->''"After my mother died, I was practically raised by NERV. Despite living with them, my father never really cared much about me, and my stepmother was 'almost afraid of me', as she said it. So I was mostly in custody by someone from NERV; send from one guardian to another. But those were the same; only when I got good grades or even more so when I was good in training, I got praise. Even Misato wasn't much better..."''\\

* ''Fanfic/ToHellAndBackArrowverse'' (''Series/{{Arrowverse}}''): Slade Wilson and Shado Gulong served as this to Oliver Queen, Barry Allen, Kara Zor-El and Kal-El during their time on Lian Yu.

* ''Fanfic/EscapeFromTheMoon'' (''WesternAnimation/MyLittlePonyFriendshipIsMagic''): In the sequel ''The Mare From the Moon'', per canon, Twilight is this to Spike, but it’s made more visible as Twilight actually refers to him as her son here, ''especially'' when Spliced starts calling her out on [[spoiler: her inadvertent stunting of his growth]].
* ''Fanfic/FallingBackwards'' and its sequel ''Flying Forwards'' (''WesternAnimation/MyLittlePonyFriendshipIsMagic''): Both stories have a rather sad variation on this trope. In it, Rainbow Dash receives brain damage after stunt gone wrong that leaves her mentally regressed to a child and ends up imprinting on Twilight as her mother. With no apparent way to fix her friend available, other than just shipping her off to a mental asylum and feeling guilty [[MyGreatestFailure over her failure to fully save her friend]], Twilight reluctantly takes Rainbow in and plays along with the whole "mommy" thing until a way to cure her can be found. [[spoiler: Ultimately no cure is found and with no other options available, Twilight [[FountainOfYouth physically regresses her to match her mental state]], so she at least has a second chance at life and accepts her new role as Rainbow's mother.]]

Despite her protests that she's just looking out for a student, she lets her live with her, packs her lunches, and makes sure she is properly punished when she does something wrong. ''Everyone'' lampshades it.

* ''Fanfic/RainbowDoubleDashsLunaverse'' (''WesternAnimation/MyLittlePonyFriendshipIsMagic''):

* ''Fanfic/SophisticationAndBetrayal'' (''WesternAnimation/MyLittlePonyFriendshipIsMagic''): The protagonist's boss Pipe Wrench becomes something of a father figure to him. Pipe Wrench's wife similarly becomes something of a mother figure, and both provide advice on how to deal with various personal problems he encounters.
* ''Fanfic/TheTwilightChild'' (''WesternAnimation/MyLittlePonyFriendshipIsMagic''): Played with when Princess Celestia admits she sees Twilight as a daughter, and Twilight points out she already has parents, whom she loves dearly. Doesn't mean she isn't touched, though.
* ''Fanfic/TheWitchOfTheEverfree'' (''WesternAnimation/MyLittlePonyFriendshipIsMagic''): Celestia was a parental substitute for Sunset before their fight, but she didn't directly acknowledge it, leading Sunset to become [[GreenEyedMonster jealous of Cadance]] for Celestia having officially adopted her. [[spoiler: After their reconciliation, Celestia starts actually calling Sunset her daughter.]]

* ''Fanfic/TheVow'' (''WesternAnimation/KungFuPanda''): Lianne comes to hold in her heart Lord Goa and Lady Jing, Shen's kindly parents, like second parents. In particular, she regards Lord Goa a true father her biological father has [[ParentalNeglect never been able to be to her]].

* "[[https://www.fanfiction.net/s/7176396/1/Of-Finding-Innocence Of Finding Innocence]]" (''Series/{{Castle}}''): While the main focus is Kate Beckett forming a relationship with Richard Castle while she's still an officer and he's writing Derrick Storm, equal importance is given to Kate's developing role as Alexis's second mother figure. While Alexis never forgets that Meredith is her biological mother, Kate is an important maternal influence in Alexis's life when Meredith just 'forgets' to be there for her daughter, with the seven-year-old Alexis eventually calling Kate 'Momma' to distinguish her from Meredith (although by her teens she has settled into calling Kate 'Mom').

* ''Fanfic/Property Of'' (Film/TransformersFilmSeries): When Annabelle Lennox is taken to Cybertron as part of a twisted 'pet trade' set up by a group of Decepticons, she is purchased by Ironhide. While most Cybertronians are unaware that humans are sentient and humans believing that they all know about the trade in full, when Sam and Mikaela (who have been purchased by Bumblebee) are brought to Ironhide's place of residence to try and calm Annabelle, they calm Annabelle by convincing her that Ironhide sees himself as her father figure, with Ironhide becoming fond of 'Softspark' even before he learns that humans are sentient.

* ''[[https://www.fanfiction.net/s/5463870/1/Property-Of Property Of]]'' (Film/TransformersFilmSeries): When Annabelle Lennox is taken to Cybertron as part of a twisted 'pet trade' set up by a group of Decepticons, she is purchased by Ironhide. While most Cybertronians are unaware that humans are sentient and humans believing that they all know about the trade in full, when Sam and Mikaela (who have been purchased by Bumblebee) are brought to Ironhide's place of residence to try and calm Annabelle, they calm Annabelle by convincing her that Ironhide sees himself as her father figure, with Ironhide becoming fond of 'Softspark' even before he learns that humans are sentient.

* ''Fanfic/PeterParkerNeedsAHug'': This ''Franchise/SpiderMan'' crossover with ''Webcomic/BatmanWayneFamilyAdventures'' has the web-slinger arrive in Gotham (because of a TrappedInAnotherWorld scenario). It takes a while, but eventually he opens up to the Bats and Batman becomes his mentor/father figure. Considering how the fic starts shortly after the events of ''Spider-Man: No Way Home'', the Bat family was ''exactly'' what the poor kid needed.

[[folder:General]]

* ''Anime/NeonGenesisEvangelion'': As in canon, in '''''MANY''''' fics portray Misato as this for Shinji and Asuka. Sometimes, that role extends to other characters as well.
* ''VideoGame/KnightsOfTheOldRepublic'': It's hard to find a fanfic for this setting where this trope ''isn't'' in play when it comes to Carth and Mission. Mission's a SatisfiedStreetRat who is either an orphan or abandoned by her parents, with her only known family being a deadbeat older brother. Carth lost his wife and son in a Sith attack, and his son would have been roughly Mission's age. [[spoiler: You later find he's alive, but training as a Sith.]] He's the only one in the party that speaks up about Mission's young age, and tries to take a protective role. So, it was an easy assumption for the fanbase to roll with.
* ''Manga/FullmetalAlchemist'': There are some fanfics that have Edward put in this role. Bonus points if he's the oldest child in an abusive or neglecting household who takes care of the kids more than the actual "parent" does. Many fics also put [[AFatherToHisMen Roy Mustang]] in this role for Ed and Al, sometimes adding Riza Hawkeye in as a mother figure as well.
* ''WesternAnimation/MyLittlePonyFriendshipIsMagic'':
** In a lot of fanfictions, it's popular to have the Cakes killed off and have Pinkie Pie as the closest thing to a relative for the Cake twins, leaving her as the ParentalSubstitute.
** Similarly, it's common for Scootaloo to be an orphan or have a neglectful home/AbusiveParents and end up being taken in by someone (examples range from members of the Mane 6 [with Twilight and Rainbow Dash being most common] to background ponies to even ''Discord''; crossovers also sometimes have characters from other fandoms taking her in) who becomes this trope for her.

[[/folder]]

* ''Fanfic/IfWishesWerePonies'': Seeing as how this is a Harry Potter crossover, there are numerous examples:

** Dumbledore is legally recognized as this to Harry, and he tries to make the Weaselys this trope for the boy. [[LockedOutOfTheLoop For numerous reasons]], it doesn't happen.

* ''[[https://www.fanfiction.net/s/13069418/1/A-Nightmare-on-Steven-Street A Nightmare on Steven Street]]'' (''WesternAnimation/StevenUniverse'' and ''Film/ANightmareOnElmStreet''): In [[https://www.fanfiction.net/s/13071232/1/A-Nightmare-on-Steven-Street-Prequel the prequel]], little Freddy Krueger comes to view Rose Quartz as this.

* ''Fanfic/NeonGenesisEvangelionSenshiNoMichi'' (''Anime/NeonGenesisEvangelion'' and ''VideoGame/StreetFighter''): Gouken took care of Shinji and Asuka after they were abandoned. As a result of being raised and trained in martial arts by a caring mentor in a peaceful, quiet environment, both children became more emotionally stable, balanced and focused than their canon selves; to the point that Asuka does not even want to think where she might be without his teachings.
