-->--'' from '''[[http://www.eyrie-productions.com/UF/FI/WOR/blades.txt Warriors Of The Outer Rim: Blades]]''' by Benjamin D. Hutchins with Anne Cross''

In the fall of 1991, a burgeoning [[{{Otaku}} anime fan]] named Benjamin D. Hutchins (who had chosen the login name "Gryphon" for the campus computer network) was attending Worcester Polytechnic Institute in Worcester, Massachusetts. He had recently fallen in love with a series called ''LightNovel/DirtyPair'', and had seen the first anime {{fanfic}}s to be posted on the Net written about it by Ryan Mathews and Larry Mann. Gryphon decided to write a ''Dirty Pair'' fanfic as well, and in an effort to demonstrate the possibilities to his friends, he churned out something he initially considered a quick-and-dirty "proof of concept" story in which he brought Kei and Yuri to WPI with a plot device from [[http://www.eyrie.net/Grill/Vault/wizard-of-waccc.txt a friend's story]] and generally let [[HilarityEnsues chaos ensue]].

Some of his friends (including, among others, John "Truss" Trussell, Rob [="ReRob"=] Mandeville, and [[HisNameReallyIsBarkeep MegaZone]]) collaborated with him on the project; they threw in a BigBad courtesy of ''BubblegumCrisis'', they packed it full of WPI in-jokes, and named the story ''Undocumented Features''.

Although Gryphon initially intended for the story to be discarded once the "real" writing began, it soon took on a life of its own. Local reception was so positive that they decided to post it on the rec.arts.anime newsgroup. Much to Hutchins's surprise, everybody who read it wanted a sequel. So the writers -- later to be known collectively as "EyrieProductionsUnlimited" -- wrote one. And another. And then some side stories, and more and more...

This is ''Undocumented Features''. Two decades after the first story was posted, new stories are still being written in its universe. It is almost certainly the greatest MegaCrossover in all of FanFiction, and possibly in all fiction, period. The result is an epic, sprawling SpaceOpera setting that stretches across several thousand years of history and ranges across (and out of) the entire galaxy, written with a sly sense of humor and an almost religious regard for the RuleOfCool.

You wanna step in? You're in for a wild ride.
----
!!''Undocumented Features'' is divided into five sets of stories. They are, in more or less chronological order by internal dating:

:'''[[http://www.eyrie-productions.com/UF/CORE/ Core]]''':The original four stories around which the rest of the series grew. The earliest works, they are also the crudest. They tell the story of how a motley group of college students became a band of immortal, spacegoing heroes. Because of their origins, they tend to be much more "jokey" in tone than the later, more serious works.

:'''[[http://www.eyrie-productions.com/UF/GA/ The Golden Age]]''':The glory years of the Wedge Defense Force, when they were effectively an interstellar United Nations, uniting the galaxy in an era of (mostly) peace and prosperity. But there are enemies lurking in the shadows, enemies who are plotting the downfall of the WDF.

:'''[[http://www.eyrie-productions.com/UF/EX/ The Exile]]''':In a single devastating strike, Maxmillian Largo of GENOM engineers the destruction of the Wedge Defense Force, tarring its members as traitors and villains with terrible efficacy. Gryphon is framed for the mass murder of a group of children and spends the next century or so on the run. Meanwhile, the galaxy falls apart as Largo expands GENOM's reach and all but turns it into a totalitarian government. The Exile period only ends when the War of Corporate Occupation ends and Largo is defeated. Gryphon has in recent years been quite critical of the earliest ''Exile'' writing (roughly 1993 to 1995) and its rather excessively angsty content; he now refers to those stories as his "crap period".

:'''[[http://www.eyrie-productions.com/UF/FI/ Future Imperfect]]''':GENOM has fallen, Gryphon is cleared, the survivors of the WDF emerge from hiding, and the galaxy starts putting itself back together. But just as all seems to be going well, the apocalypse strikes -- Ragnarok, the Final Battle, begins. Through the unexpected intervention of mortal and demimortal agencies, though, the end of all things is averted. In its wake the "second generation" are born, and their adventures begin to move into the foreground, starting with the arrival of [[RevolutionaryGirlUtena Utena Tenjou]] in Midgard, while in the darkness new enemies make their plans. Easily the largest and most diverse segment of the setting. Its crown jewel is the epic ''[[http://www.eyrie-productions.com/UF/FI/SOS/ Symphony of the Sword]]''.

:'''The New Frontier''':The next generation of stories which will become the new "present day" of the setting, this "new era" has been announced but not yet formally implemented. The extant ''[[http://www.eyrie.net/UF/FI/WOR/ Warriors Of The Outer Rim]]'' series will be the main arc of The New Frontier, much in the same way that ''Symphony Of The Sword'' is the central arc of the Future Imperfect era.

Note that stories continue to be written for all eras except the Core; at any time there are, in fact, a number of sub-series which are awaiting completion as the muse strikes various members of the collective.

!!By a conservative estimate, ''Undocumented Features'' includes elements and/or characters from (at the minimum) the following sources:

[[folder:'''Source List''']]

* ''TheAdventuresOfBuckarooBanzaiAcrossTheEighthDimension''

** Dana Sterling, the ''{{Robotech}}'' version of Jeanne Francaix. (Max and Miria's first daughter was named Komilia Jenius in ''Macross'' and Dana Sterling in ''Robotech''. UF splits the difference by calling her Komilia Dana Sterling and using Libby Jenius as an alias.)

** Isamu Dyson and Guld Bowman from ''MacrossPlus'' are both WDF pilots in the ''Rogue Squadron'' Series. Guld is also a Veritech flight instructor with a reputation for deliberately washing out candidates that he doesn't approve of [[spoiler:including Kozue Kaoru, because he resents her natural talent for flying]].

* ''VideoGame/TechRomancer''

* ''Anime/TenchiMuyo''
** Jyurai is located inside a nebula in the Enigma Sector, and as a result is somewhat isolationist and difficult to get to; subsequently its military power is often underestimated. (It's spelled ''Jyurai'' due to the early {{fansub}}s which inspired the creative team.)
** Washuu (likewise spelled "Wasyuu" because of its usage in early {{fansub}}s) is married to Kris "Redneck" Overstreet.
** Ayeka is married to Rob Shannon and is the mother of the Princess Achika.

* ''Literature/TheWarOfTheWorlds''
** The events of this novel are (mostly) historical fact -- the invasion it describes was an expeditionary force of 50 Sarmak Martians, dispatched in 1904, who limited their efforts to the British Isles as a test of equipment and tactics. When the invading force died from Earth diseases, the Sarmak entered hibernation and didn't emerge until the Earth-Mars war of the early 21st Century. The Sarmak are the oldest of the four native races of Mars.
*** The name "Sarmak" is a reference to a Creator/GeorgeAlecEffinger short story, "Mars: The Home Front" (published in the anthology ''War of the Worlds: Global Dispatches''), which used that name for Wells' Martians while they attacked the Barsoomian Martians.
** Skuld's "High-Speed Tactical Insertion System" bears a striking resemblance to the method and appearance of the Martian cylinders.
*** And is nicknamed "the Martian Cannonball."
** The Salusian cruiser HMS ''Thunder Child'' sacrifices itself to protect fleeing refugees from a Covenant invasion force of the colony world New Woking in the ministory "The Honor of Mars: A War Story", echoing the similar sacrifice of an identically-named ship in the novel.
** The Martian Foreign Legion forces in the same story include Sarmak Martians, and utilize both the tripod war machines from the original novel and the sleeker flying craft of the 1953 film adaptation.

* ''{{Wildstorm}}'' comics

(She appears to be the version predating Wildstorm's merger with DC, hence an entry under Wildstorm.)

* ''Videogame/WingCommander''
** The Kilrathi and and their deity Sivar War-God (who is another face of Norse god Tyr Grimjaws).
** The Salusians use the Terran fighter designs from ''Wing Commander'' in the UF-verse.
** Ultimate source of the Church of Man, although the version that appears in UF is greatly mutated from its origins.

* ''Film/XXx''
** Xander Cage is an agent of the IPO.

* ''YoroidenSamuraiTroopers'' (AKA ''RoninWarriors'')

* ''ComicBook/{{Watchmen}}'' -- Although the name of "The Veidt Savings and Loan" bank on Kane's World is a direct reference to ''The Man Who Laughs'' as noted above, it's not out of the realm of possibility for it to be a portmanteau reference to Adrian Veidt as well.

Feel free to correct or add anything that previous contributors have overlooked, because there's ''always'' going to be something that previous contributors have overlooked. This list is all but ''guaranteed'' to ''not'' be complete and exhaustive. No one, not even the creators, is sure how many sources have contributed to the setting over the years. (For a quick idea of how densely a single ''UF'' story can be packed with references and sources, check out [[http://www.eyrie-productions.com/Forum/dcboard.cgi?az=read_count&om=2&forum=DCForumID19&viewmode=threaded this thread]] on the EPU Forums. This is, it should be noted, for one of the ''shorter'' pieces. Also check out the quote at the top of this page, which packs ''seven'' references into a single InTheNameOfTheMoon speech.)

!!It has been confirmed that (barring unforeseen circumstances) ''UF'' will ''never'' include elements from:

* ''Series/BuffyTheVampireSlayer'' or any other MutantEnemy production
* ''Manga/DragonBall''
* ''Manga/RanmaOneHalf''[[note]]except for that one reference to Ryouga's getting-lost skills.[[/note]]
* ''Anime/YuGiOh''

A position on this list is by no means permanent, though -- ''TheLordOfTheRings'' once held a place here until the release of the Peter Jackson films.

We also have a [[Characters/UndocumentedFeatures character sheet]], with even more tropes.
----
!!This FanFic series contains examples of:

* ActionGirl: Many, many, especially in ''Symphony of the Sword''. Can you count that high? Also the Valkyries and various Einherjar.
* ActorAllusion
* AgainstMyReligion: Numerous folks assert that their religion requires them to carry weapons.
-->"First United Freespacer Church", Mac said quietly. "We have a moral aversion to getting killed."
* AGodAmI: Largo, Akio, a few others.
* AIIsACrapshoot: Mostly averted, except for Largo.
* AirVentPassageway: Part of the caper plans in ''Hellbringer and the After-School Special Mission Force #1: "The Bad Bank Caper"'' -- as Lain Iwakura says, "Oh, good... I was -hoping- we'd be hitting all the cliches on this job."
* AliensSpeakingEnglish: Strictly speaking, averted, but a remarkable number of species have names that sound like or can be slurred to sound like common names in English. Or Japanese, for that matter.
* TheAlliance
* AllPlanetsAreEarthLike: Well, excepting the {{Single Biome Planet}}s
* AllThereInTheManual: Entries from the "[[Series/BabylonFive Babylon Project]] Galactic Database" and the "The Hitchhiker's Guide to the Galaxy", as well as exclusive short stories, in the EPU Forums.
* AlphaBitch: Elisabeth Broadbank before her VillainousBreakdown, redemption and rebirth; her sister Clarissa is possibly a mix of this, TheVamp and a kind of [[BlondeRepublicanSexKitten Blonde Terrorist Sex Kitten]].
* AlternateUniverse: The Trek one in which Gryphon spent part of the Exile.
* AndroidsArePeopleToo: If they are certified as sentient by the board on Turing III. (See TuringTest below.)
* ApocalypseHow

* ArsonMurderAndJaywalking: [[Series/DoctorWho Rose Tyler's]] BPGD entry lists over a dozen degrees and honors she has earned, and finishes the list with "Bronze medal, Jericho Street Junior School Under-7 Gymnastics Team".
* AscendedFanboy: Several fans of the series have managed to join EPU, and have their {{Author Avatar}}s enter the universe.
* AuthorAppeal: Gryphon -- as he states in another EPU story -- is clearly a fan of the Jazz and Big Band eras, and it shows in many of the background details, ranging from the Art Deco architectural stylings of New Avalon to the choice of music played there on New Year's Eve.
-->"That's me; both hands on the keyboard, one foot in the Swing Age. If I could afford it, I'd drive a car with tail fins."
* AuthorAvatar: Numerous.
* AuthorVocabularyCalendar: "Sardonic." One could make a good ''UF'' drinking game from this one word.
* AwesomeMcCoolname: Quite a few, some of them aversions as they're the names of real people, and one spectacular inversion in that the real-world counterpart of [=MegaZone=] ''changed his name'' to match his avatar's.
* BadassBoast
* BadassBookworm: Kaitlyn Hutchins: bespectacled, stuttering musician ''and'' deadly samurai, all in one cute, tiger-striped package.

* BadassLongcoat: [=MegaZone,=] frequently; also Geoff Depew.
* BankRobbery: In ''Hellbringer and the After-School Special Mission Force #1: "The Bad Bank Caper"''.
* {{Bifauxnen}}: Kaitlyn mistakes Utena for a boy (admittedly at a distance, and Utena is wearing her hair short at the time) the first time she ever sees her in ''Wounded Rose''. Slightly played with in that as soon as they meet face-to-face, Kate has no problem discerning that Utena is very much a girl.
* BigBad: Surtur, possibly and ultimately; various smaller local Big Bads including Largo in the Core era and Akio [[spoiler:"Trigon"]] Ohtori in recent Future Imperfect stories.
* BigDamnHeroes: Lots of them. And more showing up all the time.
* BiTheWay: Kaitlyn, Utena, Anthy, Juri, Azalynn, and possibly ''dozens'' of others, mostly in Future Imperfect stories.
* BladeSpam: The ''Hyakken no Arashi'', which means "storm of a hundred blades" but is actually not an example of StormOfBlades. Asagiri katsujinkenryuu novices who execute the manuever successfully are promoted to journeyman.
* [[BlondeRepublicanSexKitten Blonde Terrorist Sex Kitten]]: [[spoiler:Clarissa Broadbank, once she gets out of high school.]]
* BrainwashedAndCrazy: A Jedi agent in a recent story; Shan Bastila for a while; others.
* BrickJoke: Occasionally in some of ''Symphony'' stories someone seems to recognize Utena from her CaughtOnTheJumbotron moment all the way back in ''Wounded Rose''.

* TheCaper: In ''Hellbringer and the After-School Special Mission Force #1: "The Bad Bank Caper"''.
* CatchPhrase: [=PCHammer's=] "Let's get dangerous", stolen from WesternAnimation/DarkwingDuck; the series as a whole has one in [[ElectricLightOrchestra "I have a message from another time..."]], which is almost always the first line of the title block.
* CaughtOnTheJumbotron: A camera zooms in on Utena (whose bright pink hair probably drew attention to her) during the seventh-inning stretch of the seventh game of the 2404 World Series.
* CelebrityParadox: Inverted ''and'' subverted.
* CharacterizationTags: Liberally used by the fan community surrounding EPU to differentiate the ''UF'' versions of characters from their original source versions; and to distinguish between self insert characters and their real-world counterparts in conversations referencing both.
* {{Cloudcuckoolander}}: Vaughn Gross.
* ContinuityNod: Both to its own continuity and to those of its sources.
* ConvenientlyUnverifiableCoverStory: Utena and the other Cephiran refugees in ''Symphony of the Sword'' get elaborately detailed and ''genuine'' identity records set up for them by Gryphon and [=MegaZone=] -- in other words, by the government of Zeta Cygni -- along with documentation "proving" that they are in fact refugees from a Rim colony wiped out by pirates.
* CorruptCorporateExecutive
* {{Cult}}: The Church of Kalidor, arguably the Church of Man.
* CuteMachines: Lots. Tiny Robo and Lesser Mazinger, to start with.

-->'''HK-47''': Query: You're a good miniature organic, aren't you? Yes you are. Yes you are.
* {{Cyberspace}}: Immersive interfaces are in common use, but so are traditional interfaces like modern [=GUIs=] and [=CLIs=].
* DaChief: Gryphon in the IPO, Future Imperfect era.
* DefeatMeansFriendship: Utena beating Vigdis.
* DeusExMachina: Edison Bell.
* DieHardOnAnX: The GA story ''REDNECK: Die Hardly'' is ''Die Hard'' on Salusia. Redneck even gets to say "Yippie-ki-yay, mother fucker!"
* DittoAliens: Subverted -- which is easy to do in text if the author cares to -- with many examples of subspecies and subvarieties of many different alien species -- even those who were DittoAliens in their original sources.
* DividedStatesOfAmerica: As of the early 25th century, there is a Republic of Texas separate from the United States. It is one of the last holdouts when Earthgov forces a OneWorldOrder.
* DoomedHometown: Seriously, how many times has Worcester been destroyed?
* {{Doorstopper}}: The series, as of November 2008, contains some 20 megabytes of ASCII text. If we assume an average word length of 5.1 characters, that's over four million words. Various fans have printed and bound subsets of the stories over the years, and the results have almost always been monstrously huge books.
** Some stories, like ''Hunted Rose'', clock in at over 40,000 words, which is enough to qualify for consideration in the novel category for the Nebula award.
* DoppelgangerCrossover: Inevitable, given the number of sources. The most amusing, though, is a moment when [[Series/StarTrekTheOriginalSeries Pavel Chekov]] takes [[Series/BabylonFive Alfred Bester]] into custody.
* TheDragon: As of the events of ''Code-Name Ultra'', it appears that Clarissa Broadbank has moved into this role for Shockwave Alberto, abandoning her earlier codename of [[spoiler:"Agent A"]] to become [[spoiler:"Falcon Gold"]].
* DueToTheDead: "Stolen Time" is Ben's tribute to his friend Derek Bacon after he died in RealLife in 1996. UF!Derek's ubiquitous series of guidebooks is an extension of this.
* DuelingHackers
* DysonSphere: The Zeta Cygni Dyson Sphere has the Avalon pseudocontinent and the cities of Perth and New Avalon, the home of many of the forces of good. While [[RuleOfCool cool]] and all, the Zeta Cygni sphere has created a lot of problems that they've had to write around (generally by HandWave), such as [[AssPull how it was built]], how to get an [[AWizardDidIt apparent night inside the sphere]], and what they do with [[FridgeLogic all of the energy collected]]. It's from a Core story, so it's pretty impossible to {{Retcon}} now, but had [[WordOfGod Gryphon]] known he'd still be writing in the universe 20 years later, New Avalon would probably be on a Halo.
* ElectricLightOrchestra: "I have a message from another time..."
* EmoTeen: Zoner was one 15 years before it was fashionable.
* EmpathicWeapon: Autobots plus their partners, though which is which depends on your point of view; also, arguably, Ifurita.
* TheEmpire: Numerous, both straight and subverted.
* TheEndOfTheWorldAsWeKnowIt: Ragnarok; averted in that it's, well, averted.
* TheEpic: As a whole, it's an epic story about the Wedge Defenders and their friends and families. ''Symphony of the Sword'' qualifies as an epic on its own.
* EpistolaryNovel: ''Correspondence'', the sequel to ''Star-Crossed'', as a way of fitting Tali'Shukra into the existing canon.
* EternalHero: Most of the Wedge Defenders (the non-traitorous ones, anyway) became immortal Detians, but they also share the element of returning (from the Exile) to take their rightful place as heroes of the galaxy in the Future Imperfect era. Utena is also a form of Eternal Hero, holding the ever-recurring title of Rose Prince. Various other characters may also qualify from their original sources, such as The Doctor, Optimus Prime, and the Valkyrie.
* EternalSeptember: Aversion: the Core stories preceded it, making them a snapshot of Internet culture among early-90s college students, who were the last generation to start using the Internet before it became mainstream. Notably, the first repository of anime fanfic on the net was hosted on WPI's FTP site and administered by [=MegaZone=].
* EverythingsBetterWithPrincesses: Especially princesses like LadyOfWar Amanda. Inverted by [[spoiler:Utena]], who becomes the WarriorPrince.
* TheEvilPrince: Akio Ohtori... but it's not being King that he wants.
* EvilPlan: Akio Ohtori specializes in these, especially [[spoiler:after his death]]. Largo was the biggest contributor of these in the Golden Age.
* EvilKnockoff: The Butcher was a very convincing and effective doppelganger of Gryphon, and kicked off the Exile plot.
* FakeBand: But real within the context of the series, of course: Card No. 1, The Clay Pigeons, The Art of Noise, the [[Series/DoctorWho Cyberband of Mondas]], [[RoboTech Minmay and]] [[{{Macross}} the Marauders]], The Thrashing Gnoberts, numerous unnamed groups
** A special mention should go to ''Cthia.'' Described as "one of the hottest bands in galactic music", it is composed entirely of [[Franchise/StarTrek Vulcans]], playing enormously pretentious rock on traditional Vulcan instruments in perfect blank-face no-emotion style. Cthia, however, is a ''fake'' FakeBand. They are actually a more relaxed rock band who call themselves The Illogics, Vulcans mostly from a subculture that rejected the Surakite way. They created the overcontrolled, emotionless Cthia as a joke, to parody and criticize the Surakites... only to find themselves trapped in the roles when Cthia became a ''hit''. Especially ironic is the fact that "cthia" is a Vulcan word meaning, at its root, "truth".
* FamedInStory: Hell, most of the Wedge Rats are in the history books by now.
* FamousFamousFictional: With an odd twist in that often the fictional citation will be from one of the other sources for ''UF'', and likely to be recognized by the reader ''anyway''.
* FantasticFightingStyle: The Asagiri katsujinkenryuu, among others. The Duelists' Society is built on this trope, testing melée fighting styles from around the galaxy against each other.
* FantasticRacism: Several varieties to choose from.
* FanVerse
* FasterThanLightTravel: No less than four different methods are employed by the various civilizations and organizations in the galaxy.
** Each of which is given distict advantages and disadvantages. [[SuperDimensionFortressMacross Space-fold Drives]] are useless for exploration, horrendously expensive energy-wise but are great for getting fleets around in a hurry. [[Franchise/StarTrek Warp Drives]] are medium fast but very flexible in where you can go. [[StarWars Hyperdrive]] is fast, but travelling down uncharted routes is dangerous. [[Series/BabylonFive Metaspace Drive]] is cheap (for the shipowner -- ships don't necessarily need an installed drive) and fast, but also has risks involved in getting too far off course, as well as the initial cost of setting up the metaspace gates.
** For non-ship-based FTL, there's the IPO's secret [[StargateVerse Stargate network]]. However, it can only get you to places in the network, and there were no {{Precursors}} leaving these things lying around, they're new technology. [[DungeonsAndDragons Sorcerous teleportation]] works well enough, but is limited by the power of the caster. And finally, the [[Series/DoctorWho TARDIS]] can travel to any point in space and time.
* TheFederation
* FictionalHoliday: Trope, thy name is Dantrov.
* {{Fictionary}}: Fragments of Dantrovian, Hyeruulian, Mandalorian, Kryptonian and other languages, including both ''tlhIngan Hol'' and ''klingonaase''.
** Of special note is the language of Funkotron, alleged to be a dialect of English, although this is a matter of some controversy as this excerpt from [[http://www.eyrie.net/UF/FI/SOS/kindness.txt "The Kindness of Strangers"]] shows:
--->'''[[MagicKnightRayearth Fuu Hououji]]:''' Hay-LEE DIT-SHIZZY yo! Granny-anny nevva go unda wit'a SUCKA-FOO SHOOBY-DOO dilly-o! Homeys oughta haul yo SACKY-DUMP slackit-back'a NAR SHADDAA! Prezzy SLUG-TELLY BIZZY-*BAM*!
:::(Literally, "Haley, you worthless sack of shit! My grandmother wouldn't have fallen for a sucker play like that! They ought to trade your useless ass back to [[StarWars Nar Shaddaa]]. The King shot his TV!" The last sentence is functionally equivalent to "Jesus wept.")
* FilmFic: Doc Mui builds a [=DeLorean=], and he and Marty Rose ape ''Film/BackToTheFuture''.
* FirstChurchOfMecha: [[spoiler:Corwin Ravenhair, Norse God of Mecha.]]
* FlyingCar: The "Daytona from Hell".
* TheFunInFuneral: In ''Days of Miracle and Wonder'', Gryphon urges the participants at [[spoiler:[[BubblegumCrisis Nene Romanova]]'s]] funeral to lighten up, because it's what she would have wanted. A CrowningMomentOfAwesome in an otherwise mediocre story.
* FunctionalMagic
* GenreBusting: What started as a sort of ElsewhereFic where heroines from ''LightNovel/DirtyPair'' and a villain from ''Anime/BubblegumCrisis'' meet up with [[SelfInsertFic self-inserts]] from WPI has expanded to a HighFantasy SpaceOpera [[TheEpic epic]] spanning multiple genres.
** Within {{Fanfiction}}: ''UF'' starts as {{Self Insert|Fic}} ElsewhereFic. Since many of the {{Author Avatar}}s have bands, SongFic (in concert!) was inevitable. RecursiveFic was soon made, and then added into the canon (some of it FilmFic). The Exile brings a whole era of DarkFic. Once that's over they have children with their waifus to make it KidFic, which evolves into full-blown NextGenFic in ''Warriors of the Outer Rim'' and ''Symphony of the Sword'' (itself a {{Continuation}} of ''RevolutionaryGirlUtena''). Then the Franchise/{{X-Men}} come over from an {{Alternate Universe|Fic}} and teach the UF universe's versions of themselves in an HighSchoolAU. Not to mention the in-universe SlashFic, or PatchworkFic of [[Series/BattlestarGalacticaClassic three]] [[Series/BattlestarGalacticaReimagined different versions]] of ''Battlestar Galactica'', or the FixFic elements that give Darth Vader a second chance. And somehow, it all blends together as a cohesive narrative.
* GenreSavvy
* GeniusDitz: Mirai Morisato. Although she initially gives every impression of being nothing more than a fashion-obsessed airhead, as of the events of ''Code-Name Ultra'' it's clear that Mirai is a genius at public relations and managing media -- to the point where her airhead persona may actually be little more than ObfuscatingStupidity.
* GenkiGirl: Most notably Ayami Nakajima, Admiral of the Confederate Freespacers, and more energetic at 8 in the morning than it should be legal to be.
* GentleGiant: Moose.
* GirlsLoveStuffedAnimals: Kaitlyn and "Seven", her ragged stuffed tiger; oddly implemented with Amanda's rag doll of her own brother.
* GratuitousJapanese: In addition to CallingYourAttacks and NamedWeapons the terms [[SeizaSquirm seiza]], {{kiai}}, "sou ka", and osensei make appearances.
* HappilyAdopted
* [[HauledBeforeASenateSubCommittee Hauled Before the Jedi Council]]: Bastila Shan, the Repo Men, Chad Collier, Utena Tenjou, and many more find themselves faced with a hearing before the cameras in ''The Revolution Will Be Televised''.
* HeelFaceTurn: Several, particularly in the Future Imperfect era.
* HermeticMagic
* HeroesWantRedheads: Gryphon and Kei, Redneck and Washuu, Hammer and Eiko... and that's just in the Golden Age. Many of them are [[RedheadedHero Redheaded Heroes]] in their own right, though -- especially Kei.
* {{Homage}}: One of the first AscendedFanboy avatars, who goes by the name "[=PCHammer=]", has absconded with WesternAnimation/DarkwingDuck's entire schtick.
* HumansByAnyOtherName: The various human cultures scattered throughout the galaxy, apparently evolving independently of each other.
* HumongousMecha
* ImGoingToDisneyWorld: Shouted by the Butcher of Musashi in part 6 of ''Manhunt''.
* IdiotBall: The entire Exile plot. The WDF's biggest enemy is known for being able to make robots that appear human. So when video surfaces showing their commander supposedly cheerfully gunning down little kids, a lot of them (including his girlfriend) immediately believe it's him, instead of a Buma.
* IdiosyncraticEpisodeNaming: ''The Symphony of the Sword'' is divided into major segments called, predictably, "symphonies", which are numbered. Each symphony is further divided into smaller segments whose names always include a term for a part of a symphony or some other small work of classical music: movements, pavanes, preludes, interludes, intermezzos, fanfares, entr'actes, and so on.
* IdolSinger: Numerous.
* IDoNotOwn: Averted entirely; EPU does not use disclaimers at all.
* IfItsYouItsOkay: Utena and Anthy; inverted with Kaitlyn and Miki.
* IHaveManyNames: Gryphon's many aliases during the Exile era plus his string of titles -- including but not limited to The Midgard-Knight, Fleet Captain Hutchins, Admiral Hutchins of the IPSF, Chief Hutchins of the IPO, Kaichou, the Big Kahuna, and He-Who-Could-Not-Run-Things-Without-Ruri -- is the biggest example, but there are others, not the least of which is Corwin's own list of titles.
* ImmortalityBeginsAtTwenty: The undying and unaging aspects of Detian immortality don't normally kick in until physical maturity.
* ImmortalityImmorality: Subverted, in that immortality is the reward for great and selfless service to the galaxy.
* InstantAIJustAddWater: EVE and WALL•E.
* InstantExpert: By the Future Imperfect era, "skillsofts" -- skills rendered into software form which can then be downloaded into the brain -- are available.
** In ''Weapon of Choice'', Skuld suggests that Laura Kinney take an install or two to alleviate the boredom of a medical procedure, and offers her a choice of the three skillsofts she has on hand: knitting, Centauri drunken boxing, and "how to draw comics the Bacon Comics way".
* InstantRunes
* IntellectualAnimal: Many of the creatures and species created by the Wedge Defense Force's Life Services Division, including Gojira Nakajima and arguably neotigers like Kaitlyn's "pet," Sergei.
* TheInternetIsForPorn: When Dorothy declares that her dorm room bed will be insufficient to the task of supporting both her and one other person, Corwin asks her where she got that idea. She replies, "UseNet". (Corwin then mutters, "Stop reading the alt.sex groups.")
* InTheNameOfTheMoon
* IntimateHealing: Azalynn to Saionji in ''Azalynn's Winter Holiday''.
* {{Invisibility}}
* IsThatWhatTheyreCallingItNow: This exchange from ''Symphony of the Sword No.1, 3rd Movement: A Rose for the New Year'':
-->'''Sylvie Daniels:''' Do you ever dream about me? Guy does sometimes. Don't'cha, Guy?
-->'''Guy Morgan:''' Yeah. Usually you're torturing me.
-->'''Sylvie Daniels:''' Oh, -really-. Is -that- what they're calling it these days?
** Azalynn also uses it absolutely straight with Saionji in ''Azalynn's Winter Holiday''.
* IWantMyBelovedToBeHappy: Corwin, Utena, and Anthy all have this trope in spades. It's why Corwin bows out of the potential LoveTriangle between them, and why Anthy brings him back in.
* IWantYouToMeetAnOldFriendOfMine
* {{Joisey}}: The WDF battleship ''New Jersey'' in ''Second Chances Are Illogical'', which comes complete with a "Welcome To The Garden State Parkway" sign affixed in the turbolift.
* TheJoyOfX: Derek Bacon's series of "So You/You're..." help books.
* JumpedAtTheCall
* KnockingOnHeathensDoor: The Campus Crusade for Kalidor in the WPI segments of ''The Symphony of the Sword".
* {{Kwyjibo}}: Lying Bastard Scrabble.
* LifeImitatesArt: In ''Second Chances'' (releaed in late 2003), the Mythbusters are seen on TV attempting to recreate "the famous 'Captain James Kirk makes a cannon on a primitive planet' legend," as seen in the original ''Trek'' episode "Arena". During the 2009-2010 season, the real ''Mythbusters'' actually did this for a Viewer's Choice episode. (One wonders if the Viewer in question was a ''UF'' reader...)
* LittleStowaway: Nadia and Jean of ''NadiaTheSecretOfBlueWater'', accidentally, on the SDF-17.
* LoadsAndLoadsOfCharacters: The [[Characters/UndocumentedFeatures character sheet]] has over a hundred recurring characters, and it's nowhere near complete.
* LoadsAndLoadsOfRaces: Which is only to be expected given the abundance of SF and Fantasy sources contributing to the setting, a few of which are listed on Loads And Loads of Races themselves.
* LoveDodecahedron: Several of the core characters are involved in what amount to stable extended polyamorous relationships.
* LoveTriangle: Several, of different varieties. At least two stable [[TriangRelations Type 8]] relationships form during the course of ''Symphony of the Sword'', but other triangles including some with unrequited love are also present. Gryphon himself, despite having occasional friend-lovers all over the galaxy, seems to be in a stable (and fully informed) Type 7 with Kei and Skuld.
* LovelyAngels: [[LightNovel/DirtyPair Kei and Yuri]], of course!
* MayflyDecemberRomance: Averted with Keiichi and Belldandy Morisato; as of the Future Imperfect era, they've passed their 200th anniversary (and still going strong!).
* MechanicalLifeforms: The Transformers, who also have {{Heart Drive}}s.
* MadeOfIndestructium: The setting has at least three indestructible metals, mostly from Marvel comics: Adamantium (which is technological in origin and seems to have been designed to be magic-resistant), adamantite (a similar compound which plays well with magic but which is poisonous if used internally), and uru (similar to adamantite but much heavier). Presumably vibranium is also available, given the presence of Captain America in the setting.
* MagicFromTechnology
* MegaCrossover: The UrExample.
* MetaFic: The conclusion of the Core stories.
* MexicanStandoff: A three-way standoff is described as a "Carggian standoff." Another character replies, "Well, we moved from Mexico when you showed up."
* MistakenForMurderer: Gryphon, during the Exile.
* MoralityChip: Larry Mann was ordered by Largo to create Iczer-2 without one, because Iczer-1 had shown too much moral compass to be of any use to him. (She gets better in spite of this.)
* MoreDakka: [=ReRob's=] Thundergod.
* {{Motifs}}: The bench on the SDF-17 is where many of the major changes to Marty Rose's life occur.
** AnimalMotifs: Most notably Kaitlyn's obsession with tigers.
** FairytaleMotifs: Used as a {{reconstruction}} of tropes {{deconstructed}} in ''Anime/RevolutionaryGirlUtena''. A fairy-tale romance with a god can end in a happy marriage, even if [[spoiler:it's an OT3 marriage]]. A witch can be a mother and a maiden at the same time. An order of knights can selflessly protect women from harm, but its most powerful members are women themselves.
** FlowerMotifs: Good God, the roses. See SomethingAboutARose.
** NumerologicalMotif: The Discordian {{Arc Number}}s 17 and 23 appear as the the ship numbers for the SDF-17 Wayward Son and SDF-23 Wandering Child.
* MultinationalTeam: In the Future Imperfect and New Frontiers eras, the IPO.
** Also the [[SakuraTaisen Teikokukagekidan Hanagumi]], even more so than in their source material; the ''UF'' version has members from several different planets, including a Hoffmanite and a Salusian.
* MushroomSamba: Storm's mellow time on Funkotron in ''Lost and Found''.
* MyKungFuIsStrongerThanYours: Inevitable given all the conflicts, but also this exchange in ''Symphony of the Sword:''
-->'''Kaitlyn Hutchins:''' S-s-say it. S-SAY IT!
-->'''Juri Arisagawa:''' ... Kaitlyn's kung fu is best.
* MyNaymeIs: Hyeruulian names ''look'' alien, but usually can be pronounced like English or Japanese names -- for instance, M'yl'ya "Emmy" Kyn'o'bi, the distant descendant of Master O'bi-Wann Kyn'o'bi, and Uum'y R'yuu-z'ky, Rune Knight of the Sea. Of course, the Hyeruulians insist that non-native speakers are missing certain subtle elements of the pronunciation that only they can hear.
* MythologyGag: Often very subtle, and sometimes a CrowningMomentOfAwesome.
** Example: In the forums-only story ''[[http://www.eyrie-productions.com/Forum-docs/DCForumID24/86.html Correspondence III: 2400-2410]]'' it's mentioned that a space station named Terok Nor was considered and then dismissed as a possible location for the Babylon project. "Terok Nor" is the original Cardassian name of the space station that is better known as [[Series/StarTrekDeepSpaceNine Deep Space Nine]]; the mention is a joking reference to the accusations that the concepts behind ''Series/StarTrekDeepSpaceNine'' were stolen from an early presentation about ''Series/BabylonFive'' made by Creator/JMichaelStraczynski to Paramount executives in an attempt to get backing for the latter show.
** The first time we see Utena Tenjou in ''The Symphony of the Sword'', her hair is cut short (we learn why several stories later). Although UF!Utena is very much from the TV series, she starts off looking like Movie!Utena -- at least until she lets her hair grow back out.
* NamedWeapons: Most of the {{Cool Sword}}s, especially in ''Symphony of the Sword'', are named. Liza Shustal even instructs Juniper on the importance of named weapons.
* NamesToRunAwayFromReallyFast
** Myron Dween. At first you think, oh, that's kind of an EmbarrassingFirstName, [[Franchise/TheHitchhikersGuideToTheGalaxy mostly harmless]]. But then you realize: this guy is ''Funkotroni'', and is a ''total square''. Something is definitely wrong here, [[spoiler: and indeed he was [[EvilChancellor working for GENOM]]]].
** Darth Venger (as is traditional for a Sith Lord)
** Akio Ohtori, but only if you get the connection from the anime that [[spoiler:Akio means "morning star", which is connected to both the planet Venus (love) and Lucifer (evil)]].
* NextGenFic: The ''Symphony of the Sword'' and ''Warriors of the Outer Rim'' story cycles are about the {{Author Avatar}}s' children and their friends.
* NeverBringAKnifeToAGunFight: "Overstreet's First Law of Tactics", stated, restated and expanded throughout the stories. First, from ''The Quagmire Project'':
-->Take a stick to a fistfight.\\
Take a knife to a stickfight.\\
Take a gun to a knifefight.\\
Stay out of a gunfight.
** In ''Symphony of the Sword'':
---> '''Percy "Techie" Mui:''' (to his son) To paraphrase Admiral Overstreet, bring a knife to a fistfight, a gun to a knife fight, grenades to a gunfight -- oh, hell, if you know where it's going to be beforehand, mine the area. If all else fails, there's your friend, the air strike.
** Then, "Gryphon's Expansion of Overstreet's Law of Tactics":
--->Take a stick to a fistfight.\\
Take a knife to a stickfight.\\
Take a gun to a knifefight.\\
Take a 'Mech to a gunfight.\\
Bring a lance to a 'Mech fight.
*** Followed by "Matrix Dragon's Expansion of Gryphon's Expansion":
---->If all else fails, bomb the planet.
*** And finally, "Julzz' Commentary":
---->And if all else fails, bring your friendly neighbourhood God.
* NGOSuperPower: Many, including GENOM, the Wedge Defense Force, and the International Police Organization.
* NiceHat: An unidentified extra in ''Lost and Found'' -- implied to be a thug who is trounced between scenes -- says this about Magneto's helmet, which is indeed a classic example of the trope.
* NoBisexuals: Averted in the Future Imperfect era -- there are several in the primary cast of ''Symphony of the Sword''.
* NoOSHACompliance: {{Lampshaded}} in ''Road Trip to Naboo Part 4''.
* NoodleIncident: Frequent references are made to incidents which occur in stories that are either being planned or in the process of being written but have never been published. Especially notable are two planned ''Symphony of the Sword'' stories that were announced back in 2002 but never finished due to Gryphon developing writer's block and deciding it was easier to just move on to the next Arc.
* NothingIsScarier: Hammer retreats to Utopia Planitia after Sonset, and finds an abandoned base with dead bodies lying around and all the lights turned off. Of course, everyone had just left due to GENOM's EvilPlan coming to fruition, but it sure was creepy anyway.
* NotADate: Corwin and Utena go on many of these before they wise up.
* NotMeThisTime: Mojo Jojo is quite upset, annoyed and put out when everyone assumes he must be part of the Big Fire attack on prom night -- especially since it preempts, upstages, and ruins the plan he ''did'' have to attack the girls at their graduation! CURSES!
* ObfuscatingStupidity: Prince Garon of Gamilon, Devlin Carter to a lesser degree.
* OldShame: According to Word of God, some of the Core, as well as Gryphon's "Crap Period" during the early part of the Exile.
* {{Omake}}: Mini-stories, entries from ''The Hitchhiker's Guide To The Galaxy'', excerpts from the Babylon Project Database, and TV listings for New Avalon, among other goodies, available only on the EPU Discussion Forums.
* OneSteveLimit: Being a fusion of so many stories, violating this was inevitable. We have two [[ArtificialIntelligence machine intelligences]], [[MegaZone23 EVE]] and [[WesternAnimation/WallE Eve]]. [[{{Project A-ko}} Eiko Rose]] and [[RevolutionaryGirlUtena Eiko Kageshoujo]] were both originally named [[AscendedExtra Girl A]] in Japanese. But the strangest has to be two [[StarWars Anakins]], Anakin Skywalker and [[SpellMyNameWithAnS Anakyn]] shar Atrados, who were split from the same source character at different ages and given radically different backgrounds.
* OneWorldOrder: Ruthlessly enacted by Earthgov during the period covered by the later installments of ''Symphony Of The Sword''
* OrganicTechnology: Jyuraian spaceships.
* OurElvesAreDifferent: Most of them are actually Celestial beings native to the lower heavens ([[NorseMythology Alfheim and Svartalfheim]]), akin to but less powerful than angels. Hyeruulian elves are believed to be the descendants of "colonists" who moved to Midgard.
* OutDamnedSpot: Marty Rose, in ''Dies Irae''.
* PatchworkFic: EPU gleefully mixes and matches elements from sources that have multiple continuities with a wild abandon that carries the reader along with its audacity. A good case in point would be the native and extradimensional versions of many of the Franchise/{{X-Men}} who now coexist in the UF universe.
* PhlebotinumRebel: Scott Bernard.
* PhysicalGod: Lots of 'em, including the whole Norse Pantheon, Eris and Vaughn; Corwin Ravenhair; subverted by Hiroshi Morisato, who although he is half-divine has chosen to embrace his mortal side.
* PillarOfLight: A permanent pillar emanates from Odin's palace in Asgard.
* PlanetOfHats
* {{Planetville}}: Some are imported whole from source material; others, native to the setting, are [[JustifiedTrope justified]] by the explanation that many colonies were settled almost entirely by specific racial/cultural groups -- for instance Tomodachi, Ishiyama and the other Japanese worlds.
* PleasurePlanet: Disney's World
* PlotRelevantAgeUp: Vigdis.
* {{Polyamory}}
* PostModernism: As a MegaCrossover in a ScienceFantasy setting, this is to be expected, but it goes far beyond that. Incorporating the entire storyline of ''Anime/RevolutionaryGirlUtena'' certainly helps, providing plenty of {{deconstruction}}, metatropes, and shadow girls. But even from the very first story, what is theoretically a SelfInsertFic has [[RealPersonFic real people]] vastly outnumbering the three fictional anime characters; by the end of the Core, it's also a MetaFic InSpace. See the entry on GenreBusting above.
* ThePowerOfRock: Especially prevalent with the Freespacer military operations and in ''Symphony of the Sword''.
* {{Precursors}}: Several sets, most notably the Atlanteans and the Mandaloreans, who existed several thousand years before the "current era". The creators of Halo, however, are even more ancient, having been tentatively dated to at least a ''quarter million'' years in the past.
* ProudWarriorRaceGuy: Well, besides the Klingons, several different varieties.
* PunchClockVillain: The Big Fire accountants forced into being field agents by their Q-Boss, Earl, in ''The Antianeira Incident''.
* RapeAsDrama: Well-handled: Both Kaitlyn and Utena have rapes in their backstories -- Kaitlyn's more violent than Utena's MindScrew seduction by Akio -- and it takes them both years and much support by friends and family to get over the lingering psychological aftereffects, even as both go on to be BigDamnHeroes.
** [[spoiler:Noriko]], too. Which contributes to her eventually going {{Yandere}} and doing it to [[spoiler:Hammer, of all people]].
* RaygunGothic: Usually a deliberate design aesthetic chosen by architects and artists within the setting; for instance, both New Avalon and Asgard have a lot more Art Deco elements than one might expect.
* RealLifeWritesThePlot: At one remove, maybe -- Sumire's self-exile from the Hanagumi in the backstory of ''Aegis Florea 2'' seems to reflect MichieTomizawa's retirement from ''SakuraTaisen'', complete with swansong and farewells.
** Numerous small moments throughout ''Symphony of the Sword'' -- such as the Art of Noise looking for "Batherson's College" in Toronto, the Crunch-and-Munch guy at the hockey game, and Utena and Saionji belatedly remembering the principle of specific heat -- are based on events that actually occurred to members of the writing team.
* RealPersonFic: Other than the {{Author Avatar}}s themselves, sorta kinda:
** A number of 20th-21st Century figures appear in the 25th Century courtesy of the WDF's "Project Hero", which gave selected outstanding persons the Omega-2 immortality treatment. Most notable among them is Jackie Chan, who is an Expert of Justice in the ''Symphony of the Sword'' era.
** A short story set in the early Golden Age told of [[spoiler:how the WDF enacted a special plan to give former NASA astronauts a chance to walk on the moon.]]
** A number of real people appear in Valhalla or in forces dispatched from Valhalla -- for instance, Virgil "Gus" Grissom shows up at the end of ''Clarion Call''.
** As noted in the sources folder above, a number of television personalities have counterparts in ''UF'''s 25th Century who have appeared "on screen", including but not limited to the Series/MythBusters and the Teutuls of ''Series/AmericanChopper''. However, none of them have actually been the focus of a story of their own, so they only count as Real Person Fic on a technicality.
** [[http://www.eyrie-productions.com/Forum-docs/DCForumID25/1.html Nikola Tesla]] is regarded as one of the greatest inventors in Galactic history, to the point that ''he'' tutored ''Skuld''.
* RedemptionEqualsDeath: So, so averted. Most [[TheAtoner Atoners]] end up working with the good guys.
* RememberTheNewGuy: This trope has been part of UF since Hammer was introduced, and handwaving how The New Guy had avoided being on-screen until then was raised to an art form with [[http://www.eyrie-productions.com/UF/EX/SC/corr-omni.html Correspondence]]
* RememberWhenYouBlewUpASun: Oh so many.
* RescuedFromTheScrappyHeap: As one fan once said, "''UF is where characters go to become awesome again after their original writers forget how to treat them right.''"
* ReWrite: Several stories have ended up being rendered obsolete by later story developments, and have been or are going to be rewritten to fit back into continuity -- such as the pre-Future Imperfect story ''[[http://www.eyrie-productions.com/UF/FI/cybertron.txt Cybertron Dreams]],'' now known as ''[[http://www.eyrie-productions.com/UF/FI/TF/CR/ Cybertron Reloaded]]'', and the epic "Day of Infamy".
* RewritingReality: Everything starts with the program [=CLULess=], which materializes both the [[LightNovel/DirtyPair Lovely Angels]] and [[BubblegumCrisis Largo]] -- along with a load of PoweredArmor and MechaMooks. Eventually we discover that it even remade the entire UF-verse into the PatchworkFic we know and love.
* RichBitch: Again, Liza Broadbank before her HeelFaceTurn; again, her sister Clarissa has this too.
* RichIdiotWithNoDayJob: Subverted by Prince Garon of Gamilon, who is using ObfuscatingStupidity to keep from being named as heir to the Gamilon Empire in favor of his younger sister Amanda, who not only wants the position, but whom he feels is much better suited to the job.
* RobotGirl
* RobotWar
* {{Roboteching}}: Used as a verb from the first story on.
* RougeAnglesOfSatin: Deliberate invocation in ''Last Transport'', to demonstrate Kid Flash's rather spastic -- and unintentionally funny -- typing style.
* '''RuleOfCool''': Everything. It's the editorial main objective.
* RunningGag: "Taco night"; Derek Bacon's series of "So You/You're..." guidebooks, which seem to have a volume to cover ''every'' unlikely extremity a character might find himself in.
** Subverted by the seemingly endless list of Dantrovian religious holidays celebrated by Azalynn. Although she appears to be making them up on the spot as needed or convenient, most of them, regardless of how strange or silly they are, are apparently real.
*** Mostly, they were made up by the Dantrovians due to the more conservative views of other races on the subject of sex in order to allow them more freedom there.
** Also, according to WordOfGod:
--->It's kind of an undeclared running joke in the UF universe that everyone you meet named Carter is related. Devlin's late, unlamented father was the notorious gangster Jack Carter of ''Film/GetCarter'' fame ([[MaxHeadroom Edison]] and [[Series/StargateSG1 Samantha]] are presumably Jack's estranged brother and sister). Somewhere a ways back and off on another branch in their family tree, you can find the mystic and dream explorer [[CthulhuMythos Randolph Carter]] of Boston (1874-1932?).\\
\\
[[JohnCarterOfMars Martian warlord John Carter's]] provenance as part of that same clan is harder to establish, since he himself doesn't know when he was born, but family legend claims him as the one who (ca. 1650) established what would become the American branch of the family, and thus as a fairly distant ancestor of Randolph's.\\
-- Gryphon, 3 December 2011
* SadisticTeacher: Professor Aaron Harris at WPI.
* SantaClaus: By the beginning of ''Azalynn's Winter Holiday'', Saionji (after having been trounced by Kaitlyn) has somehow acquired a new sword to replace the one she destroyed. As he was disoriented and not a little crazy at the time, he's not quite sure where it came from. He remembers a man in red with white hair and a beard giving it to him and telling him to do better with it than he did with its predecessor, but isn't sure if that were a hallucination or not, and notes that he wasn't a good enough boy that year to get a present from Father Christmas.
* ScaryDogmaticAliens: The Covenant, most of the Kilrathi.
* ScaryShinyGlasses: Kaitlyn when she confronts Garcia in ''Hunter Rose''.
* ScienceFantasy: ''UF'' qualifies in every conceivable way by mixing SciFi and {{Fantasy}} almost seamlessly.
* SciFiWritersHaveNoSenseOfScale: averted, surprisingly. Most everyone in the story happily lives in one spiral arm of the galaxy, with a coreward and rimward frontier. And then, there's this from Gryphon on the forums:
-->"Assuming she's in another [galaxy] and not somewhere in the colossal void in between the galaxies, that leaves us with only (at best modern scientific estimate) about 124,999,999,999 more to check, each containing somewhere around 500 billion solar systems. Even with a [[Series/DoctorWho TARDIS]] - even if it somehow only took one second to check each entire galaxy and move on to the next one - that search would take just under 4,000 years."
* SdrawkcabName: The realm of Oriphos, which occupies the cosmological mirror-opposite position to Cephiro.
* SelfInsertFic: And how! Practically the UrExample. However, this has been averted in the Future Imperfect era, where the focus has begun to shift to a "second generation" of protagonists, some of whom are the children of the self-inserts.
* SexFaceTurn: Saionji's "rehabilitation" via having sex with Azalynn.
* ShadowArchetype
* ShiningCity: New Avalon
* ShoutOut: See the Shout Out section in the Sources folder, above.
* ShowWithinAShow: Many, including ''[[Series/StarTrekTheOriginalSeries Battlecruiser Vengeance]]'', ''[[SakuraTaisen The Adventures of Red Lad]]'', the ''[[SakuraTaisen Crimson Lizard]]'' series of movies, ''[[Series/AmericanChopper Avalon Chopper]]'', ''[[Series/DoctorWho Dalek]] [[Film/JamesBond 207]]'', and the ''New Century {{Zatoichi}}'' films. "TV listings" for New Avalon are occasionally posted to the EPU forums listing even more programs, along with fun capsule descriptions.
** Special mention should be made of ''Professor Enigma,'' a BBC-TV series that has been running almost continuously for 500 years. Based on the adventures of the "real" [[Series/DoctorWho Doctor]] -- who has actually made a guest appearance on the show -- its current Professor is played by actress and former Companion Rose Tyler; its production staff travels around the galaxy in a real, if decrepit, TARDIS to film on location.)
* SingleBiomePlanet: Lampshaded by "[[TheyCallMeMisterTibbs Ice Planet Halloran V]]" -- yes, that's what it's officially called.
* SlashFic: In-universe example: in chapter 3 of ''Manhunt'', Vanessa Leeds reports (as part of her intelligence gathering efforts on the galaxy-wide Net) discovering the existence of FoeYay slash fans shipping Largo and Gryphon, much to the latter's disgust.
* SnowballLie: ''Cthia'' -- see FakeBand, above.
* SomethingAboutARose: Since the arrival of Utena Tenjou in Midgard and the founding of the Duelists' Society, Rose Duels have become the most common form of martial arts exhibition among the Ragnarok Wave, their families, friend and acquaintances. And [[Series/StarTrekTheNextGeneration Captain Picard]] in a Rose Duel is definitely RuleOfCool.
* SongFic: Pretty much any story with a performance by the Art of Noise in it turns into this for a while.
* SpaceOpera
* SpaceWestern: ''Star-Crossed'' is this to a tee. Settlers are trying to make a living in a hostile land when two strangers come into town, trying to escape their violent past. On a Franchise/{{Halo}}.
* SpeechImpediment: Kaitlyn Hutchins, with various subversions -- her stutter vanishes when speaking with Marty Rose or [[spoiler:either of her lovers]], and [[spoiler:it disappears entirely in her early 20s for reasons that are not yet fully explained]]. As is not uncommon in the real world, it also vanishes when she sings.
** EpilepticTrees: Could Kaitlyn's stutter have been caused by being exposed to [=NeuroKill=] in utero during ''Days of Miracle and Wonder''?
* SpinOff: ''[[http://www.eyrie-productions.com/HL/ (Gryphon and Zoner Get) Hopelessly Lost]]'', now being [[ContinuityReboot recreated]] as ''[[http://www.eyrie-productions.com/TIA/ Bubblegum Crisis: The Iron Age]]''.
* StarcrossedLovers: Gryphon and Tali from ''Star-Crossed'', natch.
* SteamPunk: The entire tech base of the planet Ishiyama -- including their ''spacecraft''; also, Corwin shows a fondness for steampunk designs, as evidenced by the construction of Tiny Robo. And for the ultimate example: after Ragnarok, the stability of the universe is maintained by a steam-powered Babbage-style difference engine of truly gargantuan proportions.
* SubspaceAnsible
* SubspaceOrHyperspace: Both and more. (See FTL Travel above)
* SuccessionCrisis: Instability in Cephiro drives a lot of the action in Symphony of the Sword.
* SuperHero
* SuperRegistrationAct
* TakeThat:
-->"... what was the name of the guy on Old Earth, the twentieth-century industrialist? Richest guy in the world, went totally nuts?"
-->"Bill Gates?" said Kei.
* TannhauserGate: Played with in chapter six of ''Cybertron Reloaded'':
-->The point was, she really -had- seen attack ships on fire off the shoulder of Orion (if by "the shoulder of Orion" you meant Betelgeuse), really -had- watched C-beams glitter in the dark near the Tanhauser gate. She'd grown accustomed to seeing epic things happen with slightly alarming regularity as a kid; had even, in some ways, started to think she might be getting a little bit jaded.
* {{Terraform}}
* ThatManIsDead: Liza Broadbank, after watching her life come crashing down around her and rebuilding it from scratch, renames herself Liza Shustal.
* ThemeNaming: The world, cities and nations of Ishiyama -- the planet where the local version of ''SakuraTaisen'' took place -- are named for members of the ''SakuraTaisen'' production team. Other planets often have names appropriate to their [[PlanetOfHats "specialties"]], such as Terpsichore III, the site of a music conference; Heston's Planet, homeworld of Mojo Jojo; and Kane's World, home to Batman.
* ThemeTuneCameo: Occasionally pieces of music from various soundtracks show up in the story as "native" compositions -- for instance, "Scarlet no Gakuen" from ''RevolutionaryGirlUtena'' became a piece Kaitlyn wrote for her school orchestra, inspired by Utena.
* ThisIsADrill
* ThisIsNotADrill
* ThisIsSomethingHesGotToDoHimself: Numerous instances both directly invoked and simply demonstrated. Most recently seen in ''Weapon of Choice'' when Laura Kinney declares that facing Kimura is something she must do herself, without help from Gryphon's forces.
* ThoseWackyNazis
* TimeToUnlockMoreTruePotential
* TimeTravel
* ThereIsOnlyOneBed: Played for laughs (well, mostly) in ''Wounded Rose'', where six people try to jam into one motel bed on the road back from Toronto. Kaitlyn, Utena, Amanda, and Azalynn end up on the single queen-sized mattress.
* ToThePain: Kaitlyn to Garcia in ''Hunter Rose'', only it's done telepathically and out of sight of the readers; we just see Garcia surrender after he views Kaitlyn's threat.
* TransformationSequence: The Rune Knights; also, in ''[[http://www.eyrie-productions.com/UF/FI/SOS/knights-3.txt Knights of the Tenth World, Part 3: Endgame]]'', Utena undergoes at least ''three'' involuntary transformation sequences in less than 15 minutes.
* TrappedInAnotherWorld: They get so many of these that they have a ''guidebook'' -- "So You've Just Arrived From A Parallel Universe" -- for newcomers, and cops on the beat in New Avalon have a standard procedure for dealing with them.
* TrueArtIsIncomprehensible: Satirized with Ragulin of the ''Ecole Musico-Technologique'' and his pretentiously avant-garde "l'Experience Sonique" in ''[[http://www.eyrie.net/UF/FI/SOS/city-of-light.txt The Rose that Blooms in the City of Light]]''; further mocked by Ragulin himself much later, after he has an epiphany and becomes an itinerant bluesman. [[invoked]]
* TuringTest: Administered by the Turing Institute on the planet Turing III. {{Artificial Intelligence}}s that pass this test are certified as sentient beings in the United Federation of Planets. However, applications have to be [[ServantRace submitted by their owners]], which given the strong AndroidsArePeopleToo nature of the setting, many of the characters view it as a form of slavery.
* UntoUsASonAndDaughterAreBorn: Lampshaded by Kozue (herself the twin of Miki). She notes that her peer group has Guy and Priss Morgan, Chip and Reiyna Mui, and Achika and Tenchi Shannon.
* VirtualSoundtrack: In virtually every EPU piece longer than a short-short since the late 90s.
* VoiceOfTheResistance: Network 23, Big Time TV, and even the BBC! TropeNamer Susan Ivanova doesn't broadcast; she likely has her hands full dealing with Derek Bacon, her CO on B6.
* WarriorHeaven: Valhalla, natch
* WarriorPrince: Actually "hard-coded" into the nature of Cephiro, where he acts as a roving "correction mechanism". Examples include Dios and ultimately [[spoiler:Utena Tenjou]].
* WaveMotionGun: Several varieties, from several sources, including the TropeNamer from ''UchuuSenkanYamato''.
* WhatMeasureIsANonHuman: Instead of a hidden moral value, it can actually be measured in terms of Spengler flux. [[ArtificialIntelligence ACIs]] run a wide range from barely sentient to emitting three times the Spengler radiation of average humans.
* WhamEpisode: ''Hunted Rose''
* WhamLine
-->"Blind we are," [[spoiler:Yoda]] said softly, as if only to himself. Then, in a slightly louder voice, he added, "Blind we have ''been''. Since the time of Nemo shar Atrados... blind we have been."
* WhoWantsToLiveForever: Subverted -- his loved ones decide to get the immortality treatment as well. Then the people who care about ''them'', until ''every single Wedge Rat'' is immortal. As are their descendants.
** Played somewhat straight in ''Aegis Florea 2'' when [[spoiler:Sumire]] is revealed to have, as a result of a combination of this Trope, VictoryIsBoring and [[spoiler:her own unrequited love for Gryphon]], spent the previous forty years in the throes of a HeroicBSOD until [[spoiler:Kei]] reboots her with a WhatTheHellHero[=/=]TheReasonYouSuckSpeech that is so scathing and insulting that she cannot help but to rouse from her self-imposed emotional stupor and get angry.
* WolverineClaws: A common cybermod, actually called "wolvers" in-world. After he arrives in the UF-verse, Wolverine is annoyed when he finds that he cannot sue for the misappropriation of his name.
* [[TheTokyoFireball The Worcester Fireball]]: See Doomed Hometown above.
* WorldTree: Yggdrassil, the original ash tree.
* WorthyOpponent: Hans von Hammer of Big Fire, at least to Biggles and Kozue Kaoru. (And vice-versa.)
* WriteWhoYouKnow: To the point that all but ''three'' of the many characters in the first story are real people.
* YouAlreadyChangedThePast: TimeTravel in UF mostly works in this way, from [[spoiler:Tobernel]]'s literal SelfFulfillingProphecy to Doc Mui having to go back and [[RetroactivePreparation save himself in the past]]. But then there are more {{Timey Wimey|Ball}} moments where characters go back in time to SetRightWhatOnceWentWrong before fading away into non-existence (though that was apparently orchestrated by resident [[DeusExMachina deus ex machinist]] Edison Bell).
* YouKillItYouBoughtIt: Akio kills Zagato and takes his place as High Priest of Cephiro. [[spoiler:Anthy later kills him, and winds up becoming High Priest herself.]]
* YouMeanXmas: Various alien holidays held at about the same time on the Galactic standard calendar, including of course the inevitable Dantrovian excuse for an ... intimate experience with like-minded individuals.
* {{Zeerust}}: Much of the civilized galaxy feels like the late 20th-early 21st century with Space Opera accoutrements. For example, 25th-century Toronto is essentially identical to Toronto ''now.'' New Avalon, a planned city built from scratch at the beginning of the 25th century, is deliberately designed to feel like a New England city circa 2000 AD. Lampshaded in one of the stories where a character says "Whenever we set out to build new things nowadays, we realize all our best stuff was made in the twentieth century, but it got knocked down, and we want it back, so we build it again." Within the setting, some 25th-century sociologists believe this is the result of having large numbers of immortals born in the 20th in the population, imposing their tastes and familiarities on the culture as a whole.)

!! ''Undocumented Features'' is large enough to have created its own internal tropes:
* '''Married Mai Waifu For Real.''' A significant percentage of the Author Avatars end up married to or in permanent long-term relationships with various hot fictional babes. Just to name a few:
** Gryphon and [[LightNovel/DirtyPair Kei]] (...and [[Manga/AhMyGoddess Skuld]], and [[SakuraWars Sumire Kanzaki]], and ...)
** Megazone and [[LightNovel/DirtyPair Yuri]]
** Rob Shannon and [[TenchiMuyo Ayeka]]
** Redneck and [[TenchiMuyo Wasyuu]]
** Hammer and [[ProjectAKo Eiko]]
** This is not just about [[HappilyEverAfter getting the girl]]. These are full-fledged relationships; the characters have children, and have to balance work and their family life.
* '''I'm With The Band.''' Pick a character, any character. They are, or were, part of a rock band or its hangers-on.
** [[Manga/AhMyGoddess Belldandy and Keiichi]]? College garage band.
** Princess Amanda of Gamilon? Private band with her brother and their bodyguards.
*** As well as Kait's old guitarist.
** [=PCHammer=]? Lead singer of the Clay Pigeons, biggest band in the galaxy at one point.
** Most of the early parts of ''Symphony of the Sword'' revolve in part around Kaitlyn Hutchins' band The Art of Noise (named for the 20th century British techno band the same way singer Englebert Humperdinck took the name of an 18th century composer).
* '''Here, Read This.''' Derek Bacon's interminable series of advice and self-help books for the person in an unusual situation is well past RunningGag territory and turning into a trope. A few confirmed titles:
** ''[[TrappedInAnotherWorld So You Just Arrived from a Parallel Dimension]]''
** ''[[ANaziByAnyOtherName So You Aren't the Master Race: Coping with the End of Your Civilization's Dreams of Conquest]]''
** ''[[SlaughterhouseFive So You Became]] UnstuckInTime''
** ''[[TomatoInTheMirror So You're Not Who You Thought You Were]]: [[ManchurianAgent Coping With Manchurian]] {{Deprogram}}ming''
** ''So You've Adopted A Kilrathi''
** ''[[AfterTheEnd So You've Just Crawled Out of a Vault: Surviving in a Post-Apocalyptic World]]''
** ''So You Fell From A Great Height: [[FallenAngel A Celestial Outcast's Survival Guide to the Mortal Plane]]''
** ''So You Are Falling from a Great Height'' (Which is, according to WordOfGod, a different book entirely from the previous title -- this one is a manual for people who've just been ejected from high-flying aerospacecraft and/or defenestrated from tall buildings...)
** ''So You're Dead: A Non-Survivor's Guide To Valhalla''
** ''So You're Unexpectedly In a War Zone''
** ''So You Don't Want the Creature to Eat You''
** ''[[Series/BattlestarGalacticaReimagined So You Escaped the Robot Apocalypse]]''
** ''So You Got Shot''
** ''So You Come From Ye 17th Centurie'' (co-written with SamuelPepys)
** ''So You've Just Returned From Beyond The Outer Rim''
** ''So You Want to Be a Space Cowboy: A Guide to Starfighter Piloting''
** ''So You Probably Shouldn't Have Eaten That''
** ''So You Come From Australia''
*** In-universe market research allegedly shows that these last two volumes are almost always purchased as a set.
