* ''Fanfic/DanganronpaParadiseLost'''s deuteragonist is Shion Nanashi, a green-haired amnesiac unusually skilled in robotics and with a massive guilt complex, who Monokuma quickly hints that he knows personally. It eventually comes to light that she is an amnesiac [[VideoGame/DanganronpaAnotherEpisodeUltraDespairGirls Monaca Towa]].

* In ''[[https://archiveofourown.org/works/38650416/chapters/96624921 Magia: A New Hope]]'', Ashley runs into Yoshida Tamura, an IdenticalStranger to Homura who experiences visions of Homura's past timelines.

* In ''Fanfic/TheVictorsProject'', District 11's first Victor, Orchus, runs away from the district years after his victory and lives in the woods for several years.

* In ''Fanfic/BlackStarPersona5'', [[VideoGame/Persona5 the Phantom Thieves]] fight against [[GreaterScopeVillain Hastur]], [[AnthropomorphicPersonification a manifestation of humanity's fear of an unknown future]] after [[CorruptPolitician Shido's]] change of heart and [[DarkMessiah Yaldabaoth]]'s defeat in the main game. Hastur bears many {{s|uspiciouslySimilarSubstitute}}imilarities to [[VideoGame/Persona2 Nyarlathotep]], from their [[InYourNatureToDestroyYourselves views on humanity]] right down to having the same {{Catchphrase}} ("That's a contradiction."/"You contradict yourself.") [[WordOfGod The author]] has confirmed that Hastur is in fact Nyarlathotep under a different alias, who had managed to return from his banishment at the end of the second game due to humanity's fear creating a hole in the Collective Unconscious which allowed him to escape.

* ''Fanfic/IgnitedSpark'': Daikoku Yaoyorozu at first appears to simply be Momo's controlling and overbearing father, created for the fic just like Itsuka's parents. But then it's revealed he lives a double life as Flect Turn, the BigBad from the ''World Heroes Mission'' movie.

* ''Fanfic/BreathOfTheWild'' features a sand seal named Kali. She's mainly featured the "Naboris" arc as the sand seal Link rides to battle Naboris itself. The only things notable about her is her [[PinkIsFeminine pink color]] and her immediate affection towards Link. She's revealed to be Epona's reincarnation in a sand seal form, and Zelda returns her to her natural horse form so that she may once again act as Link's loyal battle steed against Ganon.

* This happens a lot in ''Fanfic/{{ResonanceDays}}'' as a result of the specifics of the afterlife setting. Magical girls who become witches before dying do not identify with their old name upon arriving in the afterlife, instead using their witch name, meaning that a great deal of characters are actually the witch form of canon characters who simply don't remember or use their old name.

** Margot is actually Kirika Kure from ''Manga/PuellaMagiOrikoMagica''; the [=AO3=] version gives this away bybusing her canonical Witch name, Latria. The Madam whom she works for is Oriko Mikuni herself, though she's not a witch and simply [[EveryoneCallsHerBarkeep prefers to go by her title]].

* ''Fanfic/ABrightFlash'''s narrator is initially left unknown, even as he begins giving details eerily similar to Godzilla's origin story. The final line reveals that Godzilla was the NarratorAllAlong.

* ''Fanfic/{{Frenzy}}'' concerns Sonic investigating a SerialKiller, with their first victim being Amy Rose. The culprit is eventually revealed to be [[VideoGame/SonicTheHedgehogCD Metal Sonic]].

* ''WebOriginal/ABrightFlash'''s narrator is initially left unknown, even as he begins giving details eerily similar to Godzilla's origin story. The final line reveals that Godzilla was the NarratorAllAlong.

* ''Fanfic/SixesAndSevens'' introduces original character Emily, but the prologue implies and a later chapter confirms that she's actually this fic's version of [[ComicBook/TheInvaders Jacqueline Falsworth]].

* The second episode of ''WebVideo/SwordArtOnlineAbridged'' featured Jeffrey, a NightmareFuelStationAttendant comic relief character who believed that Jesus was ordering him to kill people. By the sixth episode, he returns as the founder of the Laughing Coffin guild, wearing a cloak and carrying a cleaver, revealing himself to be the show's version of [=PoH=].

* ''Fanfic/SharingTheNight'': Chapter 12 introduces a number of [=OCs=] to populate the ancient past. One of them is Couscous, an ambassador sent from the dragon empires to the alicorn city of Utopia. Later on, it's revealed that [[spoiler:he is in fact Discord, or at least the person that Discord was born as. What do you get when you take a magic-less pony, have his fire of life torn out by an angry alicorn, fill him with dragonflame to replace it, have him survive the apocalyptic rain of stars that destroyed civilization and gave magic to mortal life and then leave him to ponder the ruins of the world and the deaths of everyone he knew? As it so happens, you get a pony-dragon hybrid with extremely powerful and unique magic, who then sets out to create his own perfect dream world to replace the sad ruins of reality with.]]

* A retroactive example happens in the ''FanFic/BrideOfDiscord'' "verse", where Red Shoes, an OC who goes on to marry Pinkie Pie, is revealed to be Cheese Sandwich using a fake identity to avoid his ex-marefriend, who he thinks is out to get him, after said character was introduced in the show proper and the creator began to ship him with Pinkie.

* ''Fanfic/{{Frenzy}}'' concerns Sonic investigating a SerialKiller, with their first victim being Amy Rose. The culprit is eventually revealed to be [[VideoGame/SonicCD Metal Sonic]].
