A very specific variety of IntercontinuityCrossover that has proven so popular and spawned so many instances that it practically counts as its own genre: a ''Manga/RanmaOneHalf / Franchise/SailorMoon'' crossover in which girl-form Ranma becomes a member of the Sailor Senshi, or otherwise takes up the role of MagicalGirl. It is so called because Ranma almost always ends up in the SailorFuku-styled uniforms of the Senshi. ("Fuku" by itself is just Japanese for "clothes".)

This is a variety of fic particularly prominent during the '90s, as these were the two most prominent {{shojo}} and {{shonen}} series at the time; it still remains surprisingly popular.

If you want the other kind of Fuku Fic, the one that actually takes place in school and doesn't have anything to do with Ranma or Sailor Moon in some cases, check HighSchoolAU. Not to be confused with a [[TrollFic Fuk U Fic]].

* One of the best examples extant, and probably the trope maker, is ''[[http://www.ranmafics.com/Stories/Lines_of_Destiny/ Lines of Destiny]]'' by Louis-Philippe Giroux. Sadly, it's a DeadFic.
* There is an entire website dedicated to this concept, the ''Temple of Ranma's Senshi Seifuku'', located at the predictable URL of [[http://www.fukufics.com/ www.fukufics.com]].
* Although for the moment it's a DeadFic, Mark "Togashi Gaijin" Shurtleff's ''[[http://gaijinsrealm.com/relabs/index.shtml Relatively Absent]]'' is both an excellent example and an excellent [[SubvertedTrope subversion]] of the concept.
** Also on the same website is Shurtleff's incomplete ''[[http://gaijinsrealm.com/ten/index.shtml Ten of Two]]'', another subversion in which Ranma does not just join the Sailor Senshi, he ''becomes'' the Sailor Senshi. ''All'' of them.
*** Both fics are not just dead but also permanently removed from the internet with Togashi Gaijin's recent departure from the fanfiction business.
*** However, they are still available to an extent through the Internet Archive's Wayback Machine.
* Similarly, Rob "Kenko" Haynie's ''[[http://www.fanfiction.net/s/380988/1/ Paragon]]'' subverts the usual arrangements.
** Haynie's approached the FukuFic from several unusual directions. In addition to ''Paragon'', there's ''[[http://www.fanfiction.net/s/5507657/1/CATS CATS]]'' (complete) and ''Crossed Moon'' (incomplete, with only a [[http://www.knology.net/~kenjiko2/Textfiles/Crossmoonprotemp.txt prologue]] and [[http://www.knology.net/~kenjiko2/Textfiles/CrossMoon1Atemp.txt chapter one]] extant). Both are... different and both are quite good.
* ''[[http://www.fanfiction.net/s/28349/1/Sailor_Ranko Sailor Ranko]]'', by [[http://www.fanfiction.net/u/10379/Fire Duncan "Fire" Zillman]], is a fairly straightforward version with Ranma as an [[Main/{{AscendedFanboy}} Ascended Fangirl]]'s reincarnation...
** ...but Zillman's ''[[http://www.fanfiction.net/s/26926/1/Destinys_Child Destiny's Child]]'' is a much more byzantine one which has, among other things, Ranma being over ''four hundred years old'' by the time the Senshi show up. With training from [[LightNovel/{{Slayers}} Lina Inverse]].
* ''[[http://www.sailorranko.com/ The Adventures of Sailor Ranko]]'' is an entire ''webcomic'' based on this premise. More specifically, based on Zillman's story from the previous entry (evidently).
** If it continues long enough, it will most likely cover Twice in a Millennium and then Burger Becky's Sailor Ranko stories as well. And considering that Becky is involved in creating the comic...
*** Sadly it appears both the webcomic and Becky's stories are {{Dead Fic}}s.
* Stephen Tsai's ''[[http://www.fanfic.net/pub/Anime/FanFictions/Ranma/Sailor-Ranma/ Bishoujo Senshi Sailor Ranma]]'' is an early (1993 or -94) ''Ranma-Sailor Moon'' [[Main/{{Fusion}} Fusion]]. Ranma ''is'' Sailor Moon, his main fiancées are the Inner Senshi, and his magical advisor is P-chan. Usually played for laughs; for example, Ranma refuses to use the Moon Tiara Magic attack because it's too girly, and uses a Mouko Takabisha instead to finish off youma -- prompting P-chan to comment that it's many episodes too early to have learned that.
* Ozzallos' ''[[http://www.fanfiction.net/s/2797728/1/ Heir To The Empire]]'', written 2006-7, proves the subgenre is far from dead and can still spring some surprises on even the most jaded reader.
* The as-yet incomplete ''[[http://www.genom-research.com/sfr/stories/drafts/SSMM Shin Silver Millennium Monogatari]]'' by Suika Roberts is interesting in postulating a highly [[{{Magitek}} technomagical]] Moon Kingdom that fell ''half a million years ago''; Ranma is ''not'' a senshi, but the reincarnation of Beryl's little sister, who was in Serenity's palace guard. It isn't ''quite'' a pure Fuku Fic in that there are tiny {{Shout Out}}s to ''Anime/NeonGenesisEvangelion'' scattered throughout.
* ''[[http://www.fanfiction.net/s/3880683/1/Contrast_Match Contrast Match]]'' by Weebee
** Unfortunately, weebee doesn't seem to be able to continue the story.
*** A fan, however, is picking it up, fine tuning some old chapter grammar and such, and hoping to continue the story to the end. [[http://www.fanfiction.net/s/6765488/1/ You can find it here.]]
* ''[[http://www.fanfiction.net/s/3312373/1/ Reflections of Ruin]]'' manages to combine ''Ranma ½'', ''Sailor Moon'', '''and''' LovecraftianFiction.
** And GratuitousJapanese (this has since been removed from the story).
* ''[[http://www.fanfiction.net/s/3605736/1/Fist_of_the_Moon Fist of the Moon]]'', in which a ''very'' different version of ''Sailor Moon R'' is presented. Due to Ranma's influence and training, all of the Senshi become much more powerful and have abilities they don't in canon (Sailor Mars can ''fly''). Features a Ranma/Usagi pairing so there is plenty of Mamoru and Akane bashing earlier on, but both never stray into RonTheDeathEater territory and eventually get better as the story progresses. Completed, with 18 chapters.
* Not Ranma, but a similar idea plays out in ''[[http://www.fanfiction.net/s/273677/1/Sailor_Hellblazer Sailor Hellblazer]]'' where [[ComicBook/{{Hellblazer}} John Constantine]] accidentally winds up invoking a henshin pen meant for his niece and gets stuck with the role. Yes, '''THAT''' John Constantine.
* ''[[http://www.fanfiction.net/s/3530833/1/A_boy_in_the_hand A boy in the hand]]'' by [[http://www.fanfiction.net/~dogbertcarroll Dogbertcarroll]], a lighthearted (and recently-updated) story featuring a Ranma/Hotaru pairing. Note that there are two somewhat different versions of this fic on the Net -- the Fanfiction.Net version linked above, and one found on the Anime Addventure (below).
** It should probably be noted that Ranma actually becomes a Mask instead of a Senshi.
* While not primarily or solely about ''Sailor Moon''/''Ranma ½'' crossovers, ''[[http://addventure.bast-enterprises.de Anime Addventure]]'' (a choose/add your own story type site with multiple branches, storylines, and restart points) inevitably contains a number of fuku fic plotlines.
* What better way to tell that this has become an entire genre? Why, when a [[DeconstructedTrope deconstruction]] of it is [[http://www.fanfiction.net/s/5993481/1/The_Unwritten_Tales created]], of course!
* Fanfiction writer [[http://www.yggdrasil.org Chris Angel]] gave an example of how he thought a proper ''Ranma ½''/''Sailor Moon'' fic should go. It can be found [[http://www.yggdrasil.org/cross/oneshots/different.txt here]]. Unfortunately, it's only a one-shot, but the ending is great.
* ''[[http://www.asynjor.com/fanfic/sharp.html Featherbrite's Tale]]'' by Gregg "Metroanime" Sharp (located about one-third of the way down the linked page) is a FukuFic in which ''Sailor Moon'' is still fictional, but Ranma and the rest of the cast become ersatz Senshi anyway. As the winner of ''The Bet'', it is naturally predicated on one tiny change made to Ranma's life. Sadly, it's a DeadFic, twice over: Sharp got to 14 chapters of a first version, then began a rewrite that got as far as the sixth chapter, before abandoning the project entirely. However, clever readers can work out the probable ending from the information available to them by the end of the last extant chapter of the first version.
* An interesting take on this is ''FanFic/TheReturn'', where the fuku in question causes so much LossOfIdentity that Ranma becomes quite arguably an original character, even taking to using a different name.
** Written, unsurprisingly, by one of the Temple of Ranma's Senshi Seifuku forum admins.
* In the prologue of ''LemonSherbet'', a Ranma/Sailor Moon crossover lemon by John Biles, Ranma has a brief run-in with the author and actually attempts to ''veto'' the fic because of this trope. He only agrees to participate after a promise not to become a senshi (and some blackmail). [[spoiler: He never said anything about becoming a Kamen, though. While female.]]
* An interesting variation on the theme can be seen in the DeadFic ''[[http://web.archive.org/web/20070206170631/www.fanfic.net/~makoto/actamain.htm A Call To Action]]'' by Mike Koos, in which it's not Ranma but Nabiki Tendo who's Sailor Terra.
* ''[[http://www.fanfiction.net/s/2344075/1/Bishonen_Senshi_Sailor_Moon Bishonen Senshi Sailor Moon]]'' by Ryo Wolf. Ranma becomes Sailor Moon, Ryouga is Mercury, Konatsu and Ryu Kumon are Mars and Jupiter, oh, and Luna is a squirrel (according to Ranma). And yeah, the Senshi are all girls, whether they want to be or not. Sadly it appears to be a DeadFic.
* ''HalfMoon'', by SKJAM!, has a slight twist -- Usagi is the third Tendou sister instead of Akane, so the events of both ''Sailor Moon'' and ''Ranma ½'' are happening at the same time...
* In the early 1990s, one of the FIDONet discussion groups was the site of a ''Series/BabylonFive'' fanfic titled ''Sailor Babylon'', which among other things had G'Kar turning into a Senshi.
* There's a wiki that has nearly every fukufic on the internet with updates and descriptions. [[http://wiki.fukufics.com/fic:index]]
* The fanfic ''Fanfic/NoChanceForFate'' is a very thorough deconstruction of the common Fuku Fic tropes - all while keeping the story and characters intact. Not only does Ranma not become a Senshi, but common plots in this kind of crossover are either deconstructed, subverted or averted, which also extends to the canon source material. Additionally, countless lampshades are hung together with lots of snarking about things like clichè plots. Nevertheless, the story despite - or because of - it, is a good read.
