History NamedByTheAdaptation / FanWorks

** In ''Fanfic/LostAndFound'', she was given the name Chiharu Tanaka.

** The Wizard, who in the base game signs only as "M. Rasmodius", in the mod the "M" stands for "Magnus".

* The female protagonist from ''Portable'' is generally given the names Minako (a feminine variant of Minato, the male protagonist's manga name) or Hamuko (made by splitting the radicals of the last character in "protagonist"/主人公 and interpreting them as katakana; i.e. ハム/"hamu" instead of 公/"kou"). Fans in Japan once used the name Kimiko (a pun on "kimi" also meaning "you"), but it has largely fallen out in favor of the other two.

** ''Stars Above'' (which crosses over ''Manga/LuckyStar'' with ''Anime/PuellaMagiMadokaMagica''), names Konata's unnamed co-worker[[note]]the one who dressed up as [[LightNovel/HaruhiSuzumiya Yuki]][[/note]] Aya, after Creator/AyaHirano (even though Ayano was already named after her and Hirano herself appears in the source anime and manga at one point each).

[[AC:''LightNovel/DateALive'']]
* In the ''LightNovel/DateALive'' Movie ''[[Anime/DateALiveMayuriJudgement Mayuri Judgement]]'', the eponymous Mayuri had no last name. In ''Fanfic/DateAReLive'', she gains one in the form of Seraphina.

** Giorno's father is named Jacopo Giovanni. [[AdaptationExpansion Additionally, it's stated that Giorno goes by "Giovanna" as his last name to spite him.]]

** Chapter 7 of ''Diplomacy Through Schooling'' gives Suburst's late father the name Sunspot.

* The ''Pokémon'' oneshot ''[[https://www.fanfiction.net/s/12129411/1/Confrontation Confrontation]]'' gives James the full name of "James Miles William Roseworth". His rich parents are named George and Evangeline.

* In the ''Pokémon'' fic ''Fanfic/TheMyamotoProject'', James' last name is "Rochester", befitting his wealthy parentage.
* The ''Pokémon'' oneshot ''[[https://www.fanfiction.net/s/8534892/1/Of-Construction-and-Seduction Of Construction and Seduction]]'' gives Jessie's mother Miyamoto the surname of "Munasai".
* ''Fanfic/PokemonClefairyTales'' takes WordOfSaintPaul regarding Brock's surname (Harrison, according to Eric Stuart, his English voice actor) and runs with it. The existing {{fanon}} for Misty's surname and Lt. Surge's given name (respectively, Waterflower and Mathias) was also applied here. The series also gives Erika's and Sabrina's respective surnames as [=LaFleur=] (in keeping with Erika's GreenThumb thematic) and D'Avalon ([[ShownTheirWork inspired by Sabrina's French name]], [[GeniusBonus derived from a certain Arthurian character]], "Dee-AH-va-LAWN").

** Calem's surname is given as "Reyes", due to the author headcanoning him as Filipino (or the Pokemon equivalent thereof) and Reyes having a "Y" in it (as in ''[[VideoGame/PokemonXAndY Pokemon Y]]'').
