* ''Fanfic/BlueSky'' justifies this with Wheatley. [[spoiler:His BrainUploading caused him to forget most of his previous life, including his full name. Caroline later on reveals that his full name is ''Stephen'' Wheatley.]]

* ''Fanfic/InvisibleSun'': Professor Utonium's lack of a known given name is lampshaded when Dexter is asked Professor Utonium's name and can only think of "Professor".

----

* In ''Fanfic/TheStoryOfSilverKetchum'', Daenae Malcom goes by [[GenderBlenderName her]] surname "Malcom".
* In the Delia/Giovanni ''Pokémon'' oneshot ''[[https://archiveofourown.org/works/337881 Frayed Ends]]'', Delia notes that she's always been uncomfortable using Giovanni's first name. She instead prefers his last name, Giovanni.
* ''Fanfic/{{Nutricula}}'': After learning the full extent of how Katsuki bullied Izuku, including how he [[SuicideDare goaded him to kill himself]], Eijirou drops his usual friendly nicknames and refers to him as Bakugou. Katsuki grimly recognizes this as a sign of how much respect his OnlyFriend lost for him.
* ''Fanfic/InvisibleSun'': Professor Utonium's lack of a known given name is lampshaded when Dexter is asked Professor Utonium's name and can only think of "Professor".
* ''Fanfic/TheSupermen'': Wesker is generally called by his surname, and seems to prefer this as he is annoyed by Superman constantly calling him "Albert".
* In ''Fanfic/NewHopeUniversityMajorInMurder'', Earl Morale calls all his classmates by their last names. This ends up being an important clue in [[spoiler:finding out what he means when he writes "V's place" in his note- V stands for "Voss," as in Emily Voss, the Ultimate Astronomer (no one else has a name that starts with V)]].
* In the ''Fanfic/JuniorOfficers'' chapter "Heal", it's revealed that [[spoiler:Shellington]] chooses to go by his surname instead of his first name ([[spoiler:Oliver]]) because he believes he won't be taken seriously with his first name.
* ''[[https://archiveofourown.org/works/21828973?view_full_work=true Just Taken]]'', [[Music/SpiceGirls Mel and Emma]] addresses Melanie's mum as Mrs. O'Neil instead of Joan.
* After her breakup with Severus in ''Fanfic/ThePeaceNotPromised'', Lily goes back to using his last name (whereas she would previously use an AffectionateNickname) in order to send a clear message that they're no longer friends.
* ''Fanfic/NoStarsInSight'': Despite living on an abandoned island for nearly forty years with Formora as the only person he's had any form of social contact with, Enduriel continues to address Formora by her family name, Láerdhon. This is meant to demonstrate the TeethClenchedTeamwork between the two.
* ''Fanfic/TarkinsFist'': Most characters refer to Justin Mallory exclusively as Mallory or Mal. The use of his first name, Justin, by his brother Cale is explicitly noted by Mallory himself to sound odd, since everyone refers to him by his last name.

Examples of the LastNameBasis in fan works.

* ''FanFic/BlueSky'' justifies this with Wheatley. [[spoiler: His BrainUploading caused him to forget most of his previous life, including his full name. Caroline later on reveals that his full name is ''Stephen'' Wheatley]].
* ''FanFic/BecauseImNotPopularIllTryToGoOutWithAHero'' has Venom only refer to Peter by his last name.
* Examples from Fanfic/{{the Calvinverse}}:
** ''Fanfic/CalvinAndHobbesIIIDoubleTrouble'' has two characters named Rupert Chill - one human, one alien. The human Chill goes by his last name to avert confusion.
** Dr. Brainstorm of ''Fanfic/CalvinAndHobbesTheSeries'' [[InvokedTrope insists on this.]] [[DefiedTrope It does]] [[DoNotCallMePaul not work.]]

* ''FanFic/DespairsLastResort'': Chiyo Ueda, Arata Miyazaki, and Kazumi Katsuya all do this. Chiyo does it out of politeness (and uses "Ms." or "Mr." on most people), while the other two out of rudeness. Chiyo makes an exception for her ChildhoodFriend Kumiko. [[spoiler: Shortly before Shizuka's execution, Kazumi starts referring to her by first name. Arata calls Takara by her first name after she figures out his crime, but it doesn't last long since he gets executed.]]
* In the ''Fanfic/Gensokyo20XX'' series, we have this to somewhat the case with Mokou who is nicknamed "Huzi", being that her last name, Fujiwara, is alternatively pronounced and spelled Huziwara, leading for her nickname to be Huzi and she is usually referred to as such. Apparently, an age-regressed Reimu thinks her first name is her last name.
* In ''[[https://archiveofourown.org/works/14997911/chapters/34760702 The Horsewomen Of Las Vegas]]'', Wrestling/CharlotteFlair addresses almost everyone by their last names.
* At least one ''Franchise/MassEffect'' fic [[JustifiedTrope justifies]] Commander Shepard only being called by their rank or last name by explaining that no one (Shepard included) actually knows their first name.

* ''Fanfic/ThisBites'': Partially due to having a different naming convention, all of the Straw Hats call Cross by his last name instead of Jeremiah. This is also on account of Cross much preferring to be referred to as his last name instead of Jeremiah, or any variation thereof.
* ''Fanfic/ChrysalisVisitsTheHague'': The lawyer Alexander Estermann keeps this going, much to the point that the ''narration'' sticks to just referring to him as Estermann, reflecting his somewhat stuck-up professionalistic nature.
* Rei tells Kaworu to call her by her last name in chapter 11 of ''Fanfic/AdviceAndTrust'' [[spoiler:since she lost all her memories of him after dying in the battle against the 16th angel (her latest memory backup having been just before meeting him).]]

* ''Fanfic/WhereTalentGoesOnVacation''

* In ''Fanfic/NeitherABirdNorAPlaneItsDeku'', only a handful of characters have addressed Izuku by his given name: his parents, [[spoiler:Firestorm, and Alexis Luthor]]. The rest address him as "Midoriya" except for Bakugou, who calls him "Deku". This is particularly noticeable when Izuku is conversing with his parents, as he's still referred to in the narration as "Midoriya" even as his parents are referred to by their given names.
* In the ''VideoGame/HotlineMiami'' custom campaign serie ''Cold War'', the protagonist John Whitefield hates his first name and ask to be called Whitefield.
* ''Fanfic/RainbowDoubleDashsLunaverse:'' In "Nightmares Yet to Come", Midnight tends to refer to ponies by their second name exclusively (though apparently if they have a title, she'll use that as well). Her introduction mentions she does this to Trixie, who ''hates'' being called by her last name of Lulamoon due to childhood taunting, despite many attempts on Trixie's part to get her to do otherwise. So far, what she does with ponies who have only one name (like Applejack, or Raindrops) is unclear.
* In ''Webcomic/RWBYAUBirds'', RebelliousPrincess Weiss calls Blake by her surname "Belladonna".
* ''[[Creator/SetaSuzume Salvaged]]'': Johanna calls the other District 7 victors besides Blight (Kayta Hiro, Reinhold Meyer, and Khamphan "Champion" Larch) by their last names.
* In ''Fanfic/TheStoryOfSilverKetchum'', Daenae Malcom goes by [[GenderBlenderName her]] surname "Malcom".
* In the Delia/Giovanni ''Pokémon'' oneshot ''[[https://archiveofourown.org/works/337881 Frayed Ends]]'', Delia notes that she's always been uncomfortable using Giovanni's first name. She instead prefers his last name, Giovanni.
* ''Fanfic/{{Nutricula}}'': After learning the full extent of how Katsuki bullied Izuku, including how he [[SuicideDare goaded him to kill himself]], Eijirou drops his usual friendly nicknames and refers to him as Bakugou. Katsuki grimly recognizes this as a sign of how much respect his OnlyFriend lost for him.
* ''Fanfic/InvisibleSun'': Professor Utonium's lack of a known given name is lampshaded when Dexter is asked Professor Utonium's name and can only think of "Professor".

* ''Fanfic/InfinityTrainBlossomverse'': If a story has Paul London in it, he usually goes by his last name. Also a OneSteveLimit since there's another [[Anime/PokemonTheSeriesDiamondAndPearl Paul]] that's traversing the Train. Lampshaded in ''Fanfic/InfinityTrainVoyageOfWisteria'' when Amelia asks for Paul and London looks up and she has to clarify with "The one with purple hair."

* ''TarkinsFist'': Most characters refer to Justin Mallory exclusively as Mallory or Mal. The use of his first name, Justin, by his brother Cale is explicitly noted by Mallory himself to sound odd, since everyone refers to him by his last name.

* ''[[Creator/SetaSuzume Salvaged]]'': Johanna calls the other District 7 victors besides Blight (Katya Hiro, Reinhold Meyer, and Khamphan "Champion" Larch) by their last names.

* ''[[Creator/SetaSuzume Salvaged]]'': Johanna calls the other District 7 victors by their last names.
