* ''Fanfic/TheBoyWithoutAFairy'' (a darker retelling of ''Videogame/TheLegendOfZeldaOcarinaOfTime''): Link sees Saria as this due to her being the most involved in raising him as a baby. As the story progresses he begins to see Navi as this too much to her guilt.

* ''Fanfic/LightingCandles'': A tragic example. Tadashi lost his parents when he was a little kid (roughly eleven years before the events of ''Big Hero 6'', and as such spent most of his life without a father figure. So, when he gets to college, he ends up seeing Professor Callaghan as this trope, as the man always encourages him to do his best, helps him out during his worst moments, and gives a lot of useful advice. So you can imagine Tadashi's horror when he learns who started the fire...

* ''Fanfic/PeterParkerNeedsAHug'': This ''Franchise/SpiderMan'' crossover with ''Webcomics/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.

* ''Fanfic/MomentaryWeakness'' (''VideoGame/XenobladeChronicles3''): PlayedForLaughs. Eunie mentions she was going to ask Gray and Rozana to be her parents, but after hearing about [[HasTwoMommies Mio's situation]] she decides she'll hold out for more.

* ''Fanfic/BlueMoon'' (''Literature/{{Twilight}}'' and ''Series/BuffyTheVampireSlayer''): Giles recalls his own bond with Buffy when reading about Francesca, a vampire slayer who was captured, turned and killed by the Volturi, as the diaries of Francesca's Watcher, Sir Richard Gladwin, make it clear that he had a similar relationship with Francesca to Giles's bond with Buffy. [[spoiler:Francesca clearly reciprocated this affection; even after she faked her death to escape the Volturi, when she learned that Sir Gladwin was dying, she went to see him despite the risk so that she could assure him that she had survived and was happy]].

** In the second fic, Aqua and Terra seem to be attempting to do the same for Naminé and [[NamedInTheAdaptation Kiru (the Riku Replica)]], along with their canon role as this for Ventus.

* In ''[[https://www.fanfiction.net/s/14199641/1/Spider-Ninja Spider-Ninja]]'', Petra Parker was raised by Master Splinter and considers him her father. She later mentions to [[spoiler: Black Widow]] that she views April as a mother figure.

* Numerous ''Franchise/SpiderMan'' crossover fics have the web-slinger arrive in Gotham (either willingly or because of a TrappedInAnotherWorld scenario), and Batman becomes his mentor/father figure. Depending on the writer, Batman serves as either a superhero coach, a mentor, or (if Peter Parker is separated from Aunt May or ConvenientlyAnOrphan) an adopted father.

** It is [[ImpliedTrope implied]] that [[StreetUrchin Sanakan and Hugh]] see their {{mentor}} Kyril as this, as he gives them a home, food, and strength, despite having every right to turn them away.

** Olga was this to Chloe after saving the half-elf from slavery and raising her by herself in the Black Fortress. As Chloe grew up into the [[NumberTwo loyal vassal]] Olga wanted and needed her to be, the two of them would later become each other's LivingEmotionalCrutch.

* ''Fanfic/GodsAngelsAndKings'' -- ''Hail To The King'' (''Anime/NeonGenesisEvangelion'' and ''Franchise/{{Godzilla}}''): When Shinji was unable to synch with Unit 01 Misato decided to take him in, and she also became Asuka's guardian when she arrived to Tokyo-3.

* ''Anime/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.

--->'''Harshwhinny:''' ''[to Dash and Sunset]'' I am contacting your parents and informing them of the incident.\\

** Serizawa was this to Vivienne Graham like in canon's AllThereInTheManual materials, and she has a ''[[HeroicBSOD severe]]'' [[HeroicBSOD BSOD]] after she learns of his death. The BalefulPolymorph even calls him "father" a few times in both Japanese and [[AnimalTalk Kaiju Talk]] afterward.

* ''Fanfic/DanganPinguino'': Chisa winds up serving as this to Chiaki, with their interactions feeling much closer to a mother-daughter relationship, rather than of a teacher and a student. [[LampshadeHanging Lampshaded]] by Dastardly, who [[TastesLikeDiabetes practically pukes]] from seeing them together like that.

* ''Fanfic/ALoudAmongDemons'' Millie and Moxxie are slowly becoming this to Lincoln. While Moxxie is slow to realize he is starting to think of Lincoln as his son, Millie has zero problems explicitly referring to herself as the human boy's mother. Eventually, Lincoln calls the two "Mom and Dad", much to Millie's joy.
