Undocumented Features

""I am Ayanami Rei shar Atrados tal Vader," she said, "Padawan-in-Shadows to His Divine Shadow Darth Anakyn shar Atrados tal Vader, Grand Duke of Caladan, Chancellor of Santov, and Dark Lord of the Ancient and Obtenebrated Order of the Sith; journeywoman of the Asagiri Katsujinkenryuu; implacable foe of Big Fire. I will not rest until the twisted evil of Big Fire is extinguished from this galaxy... and my war begins here.""

- from Warriors Of The Outer Rim: Blades by Benjamin D. Hutchins with Anne Cross

In the fall of 1991, a burgeoning 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 Dirty Pair, and had seen the first anime fanfics 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 a friend's story and generally let chaos ensue.

Some of his friends (including, among others, John "Truss" Trussell, Rob "ReRob" Mandeville, and MegaZone) collaborated with him on the project; they threw in a Big Bad courtesy of Bubblegum Crisis, 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 "Eyrie Productions Unlimited" -- wrote one. And another. And then some side stories, and more and more...

This is Undocumented Features. Almost a quarter-century after the first story was posted, new stories are still being written in its universe. It is almost certainly the greatest Mega Crossover in all of Fan Fiction, and possibly in all fiction, period. The result is an epic, sprawling Space Opera 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 Rule of Cool.

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:

 * 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.


 * 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.


 * The Exile
 * In a single devastating strike, Maxmillien 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".


 * 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 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 Symphony of the Sword.


 * The New Frontier
 * The next generation of stories which will become the new "present day" of the setting, loosely defined as "what happens after the Federation Civil War". This "new era" has been announced but not yet formally implemented, mainly because EPU has discovered more story material in the years before the Civil War than they previously thought they had.  Eventually, the extant Warriors Of The Outer Rim series will become part of The New Frontier era, and presumably a series will emerge to act as the central arc of the era much as Symphony does for Future Imperfect.

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.

Source List
Where known, each source's contribution(s) to the setting are listed here. Very minor sources are compiled in a Shout-Out listing after.


 * The A-Team
 * Two of the CIs on the Righteous Indignation are based on Hannibal and Murdock.


 * ''Adventure Time
 * Marceline, queen of the vampires, is an old friend of Gryphon's. And a mean guitarist.
 * Flame Princess is apparently the daughter of Surtur.


 * The Adventures of Buckaroo Banzai Across the Eighth Dimension
 * The nods to this one start in the first chapter of the first story, making it the first work of fiction referenced in the series. The later large-scale Cosmic Retcon seems to have rendered it more or less historical fact.
 * The particular style of the protagonists' Mary Sueishness is inspired by the talents of Buckaroo Banzai and the Hong Kong Cavaliers: scientist / pilot / rock star / samurai / superhero / philanthropists.
 * Early in the Symphony of the Sword, Utena spots a watermelon in a hydraulic press in Corwin's workshop; Corwin promises to explain later, just as in the movie, but never does.


 * Ah! My Goddess
 * The Morisato clan on the planet Tomodachi
 * Skuld Ravenhair, mother of Corwin Ravenhair (with Gryphon)
 * By extension, Norse mythology, brought in so that the Norns exist within their proper framework.
 * Peorth is also known as Eris, and seems to favor that guise.


 * Alien Nation
 * Moose MacEchearn's freshman year roommate at Worcester Prep was a Tenctonese boy named Davy Crockett.
 * Comments made by the WPI Dean of Student Life in Duelists of the Rose indicate that the events of the movie happened in the UF 'verse not long after first contact was made with Salusia.


 * American Chopper
 * "Avalon Chopper"
 * Paul Teutul Sr., Obtenebrated Order of the Sith

"Gryphon frowned. "Hmm." He turned away for a moment, rubbing his chin thoughtfully, and then caught Saavik's eye. "Are you pondering what I'm pondering, Commander Saavik?" "I believe so, Captain," Saavik replied, then added with perfect seriousness, "though I must point out that if they called them Sad Meals, children would not buy them.""
 * Animaniacs
 * Wakko, Yakko and Dot are alien orphans raised by Marty and Eiko Rose.
 * The Goodfeathers appear as bullying children at the Warners' old orphanage, and Ralph is a security guard there.

 * Apocalypse Now
 * Part of the plot to Fulcrum of Fate, Part IV, including Master Corto, is an Homage to this film.


 * Appleseed
 * Gryphon spent time as an ESWAT member during the Exile (in the first Exile story to be written, which may not quite be completely in canon anymore.)
 * Olympus was the capital of Earth before being destroyed by GENOM and superseded by Earthdome.


 * Arpeggio of Blue Steel
 * An article from The Hitchhiker's Guide published in the EPU Forums' Featured Documents area in Fall 2014 describes "The Fleet of Fog" which beseiged the nations of Earth between 2012 and 2059 and prevented intervention by off-world allies, causing the global standard of living to plunge and prompting the so-called "Second Diaspora" of human colonization -- until they suddenly vanished.
 * In the Order of the Rose story Underground, the Fleet is briefly mentioned on-screen in such a way as to suggest that they will soon become very important to that story arc.


 * Atomic Robo
 * Robo is the creation, assistant and social secretary of Nikola Tesla. Although Tesla began constructing him in the 1920s, he was abandoned, half-built, for 400 years and wasn't completed until around the turn of the 24th-25th centuries.


 * The Aubrey-Maturin novels by Patrick O'Brian
 * A ship named the HMS Surprise in Manhunt.
 * Avast That Bloody Hammering Day (also in Manhunt).


 * Avatar: The Last Airbender (including The Legend of Korra).
 * The "Avatar" world is called Dìqiú and is a dimensional "neighbor" of the Japanese colony world Zipang; transitions from Zipang to Dìqiú and back again are easy enough (in certain places) that the governments on both sides have quiet but formal handling of such transfers, including mutual passports and such.
 * The contemporary period of Dìqiú is about a hundred years after the events of The Legend of Korra. Korra is still the Avatar, because she appears to be effectively immortal for no known reason; at least, she stopped aging at some point not too long after the events of LoK.
 * Korra is a Hutchins family friend, and served as midwife for both Corwin's birth and the birth of his and Anthy's daughter, Annabelle; she's also Corwin's godmother.
 * Azula at some point was removed from prison by Zuko in order to search for their lost mother, but somehow ended up in the hands of slavers in the "outside" universe, put into cryosleep, and then lost in a glacier on Karafuto, a different Japanese colony world. There she was found in the early 24th century after inspiring a century or two's worth of local folklore.  She took the name "Sarah Inazuma" and after reaching adulthood pursued an... eclectic career across the galaxy (including taking over the entire world of Mojave in less than two years).

 * And then there's the title of the early-2014 story Nothing That Is In Between, which is also a line from "Twilight".

 * Fallout
 * The appearance of a Hitchhiker's Guide entry to the lost colony Mojave in the EPU Forums at the end of 2013, with the brief but utterly awesome story of hitchhiker Sarah Inazuma's (AKA Princess Azula of Dìqiú's Fire Kingdom) visit to the planet, suggests that this setting has been promoted from simple shout-out to a full-bore source. (HHGTTG and Babylon Project entries usually foreshadow upcoming prominence in a main storyline.)
 * The presence of Rad-X antiradiation medication in shipboard medical supplies.
 * Azula's favorite pistol during her career as an adventuring space captain -- to the point that it is practically a trademark for "Captain Sarah L. Inazuma" -- is the weapon from Fallout: New Vegas known only as "That Gun". Having rebuilt it from a non-functional piece of junk, she eventually grew tired of having to make its unique ammunition herself and had it converted into a blaster.


 * Farscape

 * GENOM used Ikazuchi cruisers before switching to Galactic Empire equipment.
 * "Scott Bernard" was a meta-fictional in-joke about the Macross Missile Massacre who turned into a Memetic Badass over the years -- until a GENOM splinter cell missed the joke and created a "Scott Bernard" boomer to infiltrate the WDF. The project was mothballed with the fall of the WDF, and inevitably "Scott" awoke and escaped to become a Phlebotinum Rebel during the Exile, without realizing his true nature. He later plays a key role in Manhunt.
 * The Invid initially appeared as a variety of boomer-based robots; a three-part forums-only story released in January 2014 Retconned them into biomorphic race exploited by GENOM.


 * Getter Robo
 * Designed and built by Corwin, and gets considerable screen time in both A Night To Remember and Hunter Rose.
 * Getter radiation is responsible for a number of ... unusual accidents, among others the Incredible Hulk.


 * Ghostbusters
 * A franchise operation in the UF universe, one branch of which got itself in trouble by interfering in a date between Raven and Hellboy.
 * It's implied that Gryphon knew the original Ghostbusters (in their animated avatars) because he insists on addressing Ido of Gunnm as "Egon" (the two are drawn very similarly).
 * Numerous variations on Egon's "I'm terrified beyond all rational thought" line appear throughout the stories, not to mention "I like this plan. I'm proud to be a part of it."
 * Spengler flux, the measurement of the strength of an entity's soul, is named after Egon Spengler.
 * As part of a WDF operation Kei took a job with the Ghostbusters just in time to join them on their last job -- one that left them stuck in a pocket of ultra-slowed time with a demonic entity until they were rescued in the early 25th Century. (Kei escaped before the trap shut on the rest.)


 * Ghost in The Shell
 * "The Major" accompanied Ed Tivrusky when she appeared at Utena and Anthy's wedding.

 * Girls Und Panzer
 * An in-universe document (a page from Galactipedia) to be found on the EPU Forums describes "Armorsport" (also known as "Tankery" and "sensha-dō"), a tank combat sport for girls and women born in the ashes of World War II, which has expanded throughout the galaxy with humanity and is now common on virtually all human-settled worlds.

 * Wapiko is Washuu and Redneck's daughter.


 * Gunbuster
 * Noriko became the mentor, first love interest, and eventual adoptive "daughter" of PCHammer after suffering 200 years of Time Dilation (and the loss of Kazumi).

 * Lynn Minmei, who unlike her canon (and especially her Robotech) counterparts is a rock musician -- frontwoman for "Minmei and the Marauders".

 * Team Fortress 2
 * The Sniper appears as "Mr. Lowrie" in Prescott's Bluff, a ministory posted to the EPU forums in June 2009.


 * Tech Romancer

 * Tenchi Muyo! Ryo-Ohki
 * 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 fansubs which inspired the creative team.)
 * Washuu (likewise spelled "Wasyuu" because of its usage in early fansubs) is married to Kris "Redneck" Overstreet.
 * Ayeka is married to Rob Shannon and is the mother of the Princess Achika.
 * An adult Sasami is the current Empress of Jyurai.

 * Transformers
 * Cybertron is a part of the galactic civilization.
 * Autobots are everywhere humans are, practically.
 * The Beast Warriors entered the UF-verse from a parallel dimension.

 * WALL-E
 * EVE is a prototype robot from Stark Industries, who returns from her first, test mission with not only her designated target but also a legendary lost Minbari ghost ship (The Queen of Ranroon) and WALL-E.


 * The War of the Worlds
 * 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 George Alec Effinger 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
 * Caitlin Fairchild of Gen13 plays a small but critical role in the ministory The Balance; her acquisiton of superpowers occurs well off-screen between the opening and closing of that story. (She appears to be the version predating Wildstorm's merger with DC, hence an entry under Wildstorm.)


 * Wing Commander
 * 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.

 * Xander Cage is an agent of the IPO.


 * Yoroiden Samurai Troopers (AKA Ronin Warriors)
 * Many of the fighters gathered by at Ohtori Institute in Oriphos.

 * Pokémon -- Wapiko has brought home six Jigglypuffs, even though Pokemon aren't supposed to exist in New Avalon.

 * Tom Lehrer -- While jokingly calculating on his fingers how "too much" older he is than Utena in Christmas Rose, MegaZone briefly quotes the song "New Math".
 * A Touch of Frost -- According to Word of God, Corwin's threat to in Sympathy For the Devil was inspired by a moment in that series when the normally-happy-go-lucky Detective Inspector Jack Frost suddenly shifted entirely into Bad Cop mode with a suspect who was about to get away with a crime.

 * The War of the Worlds (The TV series) -- The Sarmak Martians use the Catch Phrase "To life immortal" from this series.
 * 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.
 * Winnie the Pooh -- a small stand of trees on the campus of Deedlit Satori Mandeville Memorial Institue is called "The Single-Acre Wood".
 * Wise Blood -- In Manhunt chapter three, Gryphon resists the urge to quote "Where you are ain't no good unless you can get away from it" from this 1979 film.

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 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 In the Name of the Moon speech.)

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

 * Buffy the Vampire Slayer or any other Mutant Enemy production
 * Dragonball
 * Dragonriders of Pern
 * My Little Pony: Friendship Is Magic
 * Naruto
 * Ranma ½
 * The Walking Dead or any other Zombie Apocalypse setting
 * Yu-Gi-Oh

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

We also have a character sheet, with even more tropes.

This Fanfic series contains examples of:
""First United Freespacer Church", Mac said quietly. "We have a moral aversion to getting killed.""
 * Action Girl: Many, many, especially in Symphony of the Sword. Can you count that high? Also the Valkyries and various Einherjar.
 * Actor Allusion
 * Against My Religion: Numerous folks assert that their religion requires them to carry weapons.

""We're waiting for Special Detail. Or Avatar Korra. You don't happen to know where she is?" "We all have to be together for that to work," Karana said seriously. "Only by all our powers combined can we summon the Avatar." The cop blinked.  "Really?" Karana snorted.  "No," she said.  "Don't be a dope.""
 * A God Am I: Largo, Akio, a few others.
 * AI Is a Crapshoot: Mostly averted, except for Largo.
 * Air Vent Passageway: 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."
 * Aliens Speaking English: 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.
 * The Alliance
 * All Planets Are Earthlike: Well, excepting the Single Biome Planets
 * All There in the Manual: Entries from the "Babylon Project Galactic Database" and "The Hitchhiker's Guide to The Galaxy", as well as exclusive short stories, in the EPU Forums.
 * All Your Powers Combined: Mocked in the forums-only story Fire Hazards:

""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.""
 * Alpha Bitch: Elisabeth Broadbank before her Villainous Breakdown, redemption and rebirth; is possibly a mix of this, The Vamp and a kind of Blonde Terrorist Sex Kitten.
 * Alternate Universe: The Trek one in which Gryphon spent part of the Exile.
 * Androids Are People, Too: If they are certified as sentient by the board on Turing III. (See Turing Test below.)
 * Apocalypse How
 * Applied Phlebotinum: Beyond the "ordinary" technologies of the space opera setting, there is the "Overtechnology" controlled by the Wedge folks, even well into the Future Imperfect period.
 * Are You Pondering What I'm Pondering?: Done in perfect Pinky and the Brain style at least once, in Manhunt; variants can be found elsewhere throughout.
 * Arson, Murder, and Jaywalking: 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".
 * Ascended Fanboy: Several fans of the series have managed to join EPU, and have their Author Avatars enter the universe.
 * Author Appeal: 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.

"HK-47: Query: You're a good miniature organic, aren't you? Yes you are. Yes you are."
 * Author Avatar: Numerous.
 * Author Vocabulary Calendar: "Sardonic." One could make a good UF drinking game from this one word.
 * Awesome McCoolname: Quite a few, some of them aversions as they're the names or nicknames of real people, and one spectacular inversion in that the real-world counterpart of MegaZone legally changed his name to match his avatar's.
 * Badass Boast
 * Badass Bookworm: Kaitlyn Hutchins: bespectacled, stuttering musician and deadly samurai, all in one cute, tiger-striped package.
 * Badass Cape: Baron Lord Wolfgang Amadeus Fahrvergnugen is never seen without one.
 * Badass Family: The Hutchins clan; to a lesser degree, Megazone's brood.
 * Badass Longcoat: MegaZone, frequently; also Geoff Depew.
 * Bald of Awesome: MegaZone.
 * Bank Robbery: 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.
 * Big Bad: Surtur, possibly and ultimately; various smaller local Big Bads including Largo in the Core era and Akio Ohtori in recent Future Imperfect stories.
 * Big Damn Heroes: Lots of them. And more showing up all the time.
 * Bi the Way: Kaitlyn, Utena, Anthy, Juri, Azalynn, and possibly dozens of others, mostly in Future Imperfect stories.
 * Blade Spam: The Hyakken no Arashi, which means "storm of a hundred blades" but is actually not an example of Storm of Blades. Asagiri katsujinkenryuu novices who execute the manuever successfully are promoted to journeyman.
 * Blonde Terrorist Sex Kitten:
 * Brainwashed and Crazy: A Jedi agent in a recent story; Shan Bastila for a while; others.
 * Brick Joke: Occasionally in some of Symphony stories someone seems to recognize Utena from her Caught on the Jumbotron moment all the way back in Wounded Rose.
 * Brother-Sister Incest: Strongly implied between Amanda and Garon Dessler; taken to a tragic extreme with Touga and Nanami Kiryuu.
 * The Cameo: Raymond Burr as himself in Aegis Florea, Part Two: Commander Moreau Reprise; assorted Shout Outs)
 * Caped Mecha: The heavily modified Zaku Corwin Ravenhair pilots in a G Gundam exhibition fight.
 * The Caper: In Hellbringer and the After-School Special Mission Force #1: "The Bad Bank Caper".
 * Catch Phrase: PCHammer's "Let's get dangerous", stolen from Darkwing Duck; the series as a whole has one in "I have a message from another time...", which is almost always the first line of the title block.
 * Caught on the Jumbotron: 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.
 * Celebrity Paradox: Inverted and subverted.
 * Characterization Tags: 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.
 * Color Character: The Red Lensman (Kei) and the Green Lensman (Wakaba) are individual people, though other colors like Blue and Grey refer to current assigned duties. In-Universe, we have the Scarlet Sentinel comics.
 * Composite Character: Several:
 * Colonel Slade of the UF Sky Raiders is kind of a cross between Slade from Teen Titans and Colonel Duray of the City of Heroes Sky Raiders.
 * Zuse from An Avatar In New Avalon is a blend of Zuse from Tron: Legacy with Roman Torchwick and Junior (both from RWBY) and classic suit-and-bowler Edward Nygma.
 * Continuity Nod: Both to its own continuity and to those of its sources.
 * Conveniently Unverifiable Cover Story: 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.
 * Cool Airship: Corwin owns one, and it's stored at the top of one of the tallest buildings in New Avalon.
 * Corrupt Corporate Executive
 * Cosmic Retcon: Core 4 (Crossroads) did one in which the many fictional things created by CLULESS became fully integrated into reality, and the self-inserts lost awareness of how their reality seemed to be based on 20th-Century fiction.
 * Cult: The Church of Kalidor, arguably the Church of Man.
 * Cute Machines: Lots. Tiny Robo and Lesser Mazinger, to start with.
 * Cuteness Proximity: Often. They even have HK-47 doing it.

"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*!"
 * Cyberspace: Immersive interfaces are in common use, but so are traditional interfaces like modern GUIs and CLIs.
 * Da Chief: Gryphon in the IPO, Future Imperfect era.
 * Defeat Means Friendship: Utena beating Vigdis.
 * Deus Ex Machina: Edison Bell.
 * Die Hard on an X: The GA story REDNECK: Die Hardly is Die Hard on Salusia. Redneck even gets to say "Yippie-ki-yay, mother fucker!"
 * Ditto Aliens: 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 Ditto Aliens in their original sources.
 * Divided States of America: 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 One World Order.
 * Doomed Hometown: Seriously, how many times has Worcester been destroyed?
 * Doorstopper: As of June 2014 the series contains some 27.4 megabytes of ASCII text. If we assume an average word length of 5.1 characters, that's over five and a half 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.
 * Doppelganger Crossover: Inevitable, given the number of sources. The most amusing, though, is a moment when Pavel Chekov takes Alfred Bester into custody.
 * The Dragon: 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 to become.
 * Due to the Dead: "Stolen Time" is Ben's tribute to his friend Derek Bacon after he died in Real Life in 1996. UF!Derek's ubiquitous series of guidebooks is an extension of this.
 * Dueling Hackers
 * Dyson Sphere: 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 cool and all, the Zeta Cygni sphere has created a lot of problems that they've had to write around (generally by Hand Wave), such as how it was built, how to get an apparent night inside the sphere, and what they do with all of the energy collected. It's from a Core story, so it's pretty impossible to Retcon now, but had Gryphon known he'd still be writing in the universe 20 years later, New Avalon would probably be on a Halo.
 * Electric Light Orchestra: "I have a message from another time..."
 * Emo Teen: Zoner was one 15 years before it was fashionable.
 * Empathic Weapon: Autobots plus their partners, though which is which depends on your point of view; also, arguably, Ifurita.
 * The Empire: Numerous, both straight and subverted.
 * The End of the World as We Know It: Ragnarok; averted in that it's, well, averted.
 * The Epic: 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.
 * Epistolary Novel: Correspondence, the sequel to Star-Crossed, as a way of fitting Tali'Shukra into the existing canon.
 * Eternal Hero: 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.
 * Eternal September: 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.
 * Ethical Slut: Pretty much the universal perception of the Dantrovians.  It's not exactly wrong, either.
 * Everyone Went to School Together: At WPI, of course.
 * Everything's Better with Princesses: Especially princesses like Lady of War Amanda. Inverted by, who becomes the Warrior Prince.
 * The Evil Prince: Akio Ohtori... but it's not being King that he wants.
 * Evil Plan: Akio Ohtori specializes in these, especially . Largo was the biggest contributor of these in the Golden Age.
 * Evil Knockoff: The Butcher was a very convincing and effective doppelganger of Gryphon, and kicked off the Exile plot.
 * Fake Band: But real within the context of the series, of course: Card No. 1, The Clay Pigeons, The Art of Noise, the Cyberband of Mondas, Minmay and the Marauders, Baron Zoria and the Circle of Horns, The Thrashing Gnoberts, Discarded Weapons, 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 Vulcans, playing enormously pretentious rock on traditional Vulcan instruments in perfect blank-face no-emotion style. Cthia, however, is a fake Fake Band. 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".
 * Famed in Story: Hell, most of the Wedge Rats are in the history books by now.
 * Famous, Famous, Fictional: 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.
 * Fantastic Fighting Style: The Asagiri katsujinkenryuu, among others. The Duelists' Society is built on this trope, testing melée fighting styles from around the galaxy against each other.
 * Fantastic Racism: Several varieties to choose from.
 * Fan Verse
 * Faster-Than-Light Travel: No less than four different methods are employed by the various civilizations and organizations in the galaxy.
 * Each of which is given distinct advantages and disadvantages. Space-fold Drives are useless for exploration, horrendously expensive energy-wise but are great for getting fleets around in a hurry. Warp Drives are medium fast but very flexible in where you can go. Hyperdrive is fast, but travelling down uncharted routes is dangerous. 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 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. Sorcerous teleportation works well enough, but is limited by the power of the caster. And finally, the TARDIS can travel to any point in space and time.
 * The Federation
 * Fictional Document: A fair number exist, and the count keeps growing:
 * The various Bacon Group comics, some of which surface in text form as UF stories.
 * Text from Derek Bacon's series of advice and self-help books (see Here, Read This, below) has not really appeared "on-screen" in significant quantities, but entries from their tables of contents and indices have.
 * The late-2013-to-early-2014 surge of stories based on and growing out of Avatar: The Last Airbender have resulted in several books written by various Avatar characters, mainly Sokka, being added to the list. These include Crazy from the Heat, The Adventures of Snow Savage and Dirt Girl, To Wang Fire, Thanks for Everything! Ty Lee, and the classic children's book The Princess in the Moon, all by Sokka, and (apocryphally, at least) Ty Lee's Master Sokka, You're Drunk!
 * There is an entire subforum on the EPU Forums for in-universe documents that add a little something extra to one's enjoyment of existing stories -- or foreshadow upcoming releases.
 * Above and beyond any of these other efforts is Challenging the Cold Silence: The Inside Story of Project Phoenix Flight, a coffee-table book about Dìqiú's first manned moon landing which appeared in a Symphony of the Sword installment. This massive volume is being written and illustrated in its entirety for PDF release by Gryphon and other EPU staff members.  Excerpts and other in-universe documents about it are available in the mean time.
 * Fictional Holiday: 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 "The Kindness of Strangers" shows:


 * (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 Nar Shaddaa. The King shot his TV!" The last sentence is functionally equivalent to "Jesus wept.")

"Would you rather I made up painfully awkward, obviously contrived Future Slang the way they do in cyberpunk-themed RPGs? Chummer."
 * Film Fic: Doc Mui builds a DeLorean, and he and Marty Rose ape Back to The Future.
 * First Church of Mecha:
 * Flying Car: The "Daytona from Hell".
 * The Fun in Funeral: In Days of Miracle and Wonder, Gryphon urges the participants at funeral to lighten up, because it's what she would have wanted. A Crowning Moment of Awesome in an otherwise mediocre story.
 * Functional Magic
 * Future Slang: Generally averted, unless it comes from one of the sources to begin with.

- Gryphon

"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?"
 * Genre Busting: What started as a sort of Elsewhere Fic where heroines from Dirty Pair and a villain from Bubblegum Crisis meet up with self-inserts from WPI has expanded to a High Fantasy Space Opera epic spanning multiple genres.
 * Within Fan Fiction: UF starts as Self-Insert Fic Elsewhere Fic. Since many of the Author Avatars have bands, Song Fic (in concert!) was inevitable. Recursive Fic was soon made, and then added into the canon (some of it Film Fic). The Exile brings a whole era of Dark Fic. Once that's over they have children with their waifus to make it Kid Fic, which evolves into full-blown Next Gen Fic in Warriors of the Outer Rim and Symphony of the Sword (itself a Continuation of Revolutionary Girl Utena). Then the X-Men come over from an Alternate Universe Fic and teach the UF universe's versions of themselves in an High School AU. Not to mention the in-universe Slash Fic, or Patchwork Fic of three different versions of Battlestar Galactica, or the Fix Fic elements that give Darth Vader a second chance. And somehow, it all blends together as a cohesive narrative.
 * Genre Savvy
 * Genius Ditz: 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 Obfuscating Stupidity.
 * Genki Girl: Most notably Ayami Nakajima, Admiral of the Confederate Freespacers, and more energetic at 8 in the morning than it should be legal to be.
 * Gentle Giant: Moose.
 * Girls Love Stuffed Animals: Kaitlyn and "Seven", her ragged stuffed tiger; oddly implemented with Amanda's rag doll of her own brother.
 * "Glad to Be Alive" Sex: Occurred in mass quantities after the Ragnarok, producing the so-called "Ragnarok Wave" some nine months later.
 * Gratuitous Japanese: In addition to Calling Your Attacks and Named Weapons the terms seiza, Kiai, "sou ka", and osensei make appearances.
 * Happily Adopted
 * Harmful to Touch: Touching another Lensman's lens induces pain, and eventually death if held for long enough. However, it is possible to carry them around in boxes and such -- you can steal a lens, but you could never use it.  Skuld was smart enough to prevent them becoming Artifacts of Death though; after a Lensman dies, his Lens simply becomes inert.
 * 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.
 * Heel Face Turn: Several, particularly in the Future Imperfect era.
 * Hermetic Magic
 * Heroes Want Redheads: Gryphon and Kei, Redneck and Washuu, Hammer and Eiko... and that's just in the Golden Age. Many of them are Redheaded Heroes in their own right, though -- especially Kei.
 * Homage: One of the first Ascended Fanboy avatars, who goes by the name "PCHammer", has absconded with Darkwing Duck's entire schtick.
 * Humans by Any Other Name: The various human cultures scattered throughout the galaxy, apparently evolving independently of each other.
 * Humongous Mecha
 * I Do Not Own: Averted entirely; EPU does not use disclaimers at all.
 * I Have Many Names: 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.
 * I Want My Beloved to Be Happy: Corwin, Utena, and Anthy all have this trope in spades. It's why Corwin bows out of the potential Love Triangle between them, and why Anthy brings him back in.
 * I Want You to Meet An Old Friend of Mine
 * I'm Going to Disney World: Shouted by the Butcher of Musashi in part 6 of Manhunt.
 * Idiot Ball: 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.
 * Idiosyncratic Episode Naming: 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.
 * Idol Singer: Numerous.
 * If It's You It's Okay: Utena and Anthy; inverted with Kaitlyn and Miki.
 * Immortality Begins At Twenty: The undying and unaging aspects of Detian immortality don't normally kick in until physical maturity.
 * Immortality Immorality: Subverted, in that immortality is the reward for great and selfless service to the galaxy.
 * Instant AI, Just Add Water: Eve and WALL-E.
 * Instant Expert: 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".
 * Instant Runes
 * Intellectual Animal: 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.
 * The Internet Is for Porn: 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.")
 * In the Name of the Moon
 * Intimate Healing: Azalynn to Saionji in Azalynn's Winter Holiday.
 * Invisibility
 * Is That What They're Calling It Now?: This exchange from Symphony of the Sword No.1, 3rd Movement: A Rose for the New Year:

"Kaitlyn Hutchins: S-s-say it. S-SAY IT! Juri Arisagawa: ... Kaitlyn's kung fu is best."
 * Azalynn also uses it absolutely straight with Saionji in Azalynn's Winter Holiday.
 * 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.
 * The Joy of X: Derek Bacon's series of "So You/You're..." help books.
 * Jumped At the Call
 * Knocking on Heathens' Door: The Campus Crusade for Kalidor in the WPI segments of ''The Symphony of the Sword".
 * Kwyjibo: Lying Bastard Scrabble.
 * A Lady on Each Arm: Both Gryphon and Yoneda at the end of Aegis Florea 2.
 * Large and In Charge: Derek Bacon, MegaZone.
 * Life Imitates Art: 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...)
 * Little Stowaway: Nadia and Jean of Nadia: The Secret of Blue Water, accidentally, on the SDF-17.
 * Loads and Loads of Characters: The character sheet has over a hundred recurring characters, and it's nowhere near complete.
 * Loads and Loads of Races: 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.
 * Love Dodecahedron: Several of the core characters are involved in what amount to stable extended polyamorous relationships.
 * Love Triangle: Several, of different varieties. At least three stable 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.
 * Lovely Angels: Kei and Yuri, of course!
 * Mayfly-December Romance: Averted with Keiichi and Belldandy Morisato; as of the Future Imperfect era, they've passed their 200th anniversary (and still going strong!).
 * Mechanical Lifeforms: The Transformers, who also have Heart Drives.
 * Made of Indestructium: 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.
 * Magic From Technology
 * Mega Crossover: The Ur Example.
 * Meta Fic: The conclusion of the Core stories.
 * Mexican Standoff: A three-way standoff is described as a "Carggian standoff." Another character replies, "Well, we moved from Mexico when you showed up."
 * Mistaken for Murderer: Gryphon, during the Exile.
 * Morality Chip: 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. (Iczer-2 gets better in spite of this.)
 * More Dakka: ReRob's Thundergod.
 * Motifs: The bench on the SDF-17 is where many of the major changes to Marty Rose's life occur.
 * Animal Motifs: Most notably Kaitlyn's obsession with tigers.
 * Fairy Tale Motifs: Used as a Reconstruction of tropes Deconstructed in Revolutionary Girl Utena. A fairy-tale romance with a god can end in a happy marriage, even if . 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.
 * Flower Motifs: Good God, the roses. See Something About a Rose.
 * Numerological Motif: The Discordian Arc Numbers 17 and 23 appear as the the ship numbers for the SDF-17 Wayward Son and SDF-23 Wandering Child.
 * Multinational Team: In the Future Imperfect and New Frontiers eras, the IPO.
 * Also the 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.
 * Mushroom Samba: Storm's mellow time on Funkotron in Lost and Found.
 * My Kung Fu Is Stronger Than Yours: Inevitable given all the conflicts, but also this exchange in Symphony of the Sword:

"Take a stick to a fistfight. Take a knife to a stickfight. Take a gun to a knifefight. Stay out of a gunfight."
 * My Little Panzer: Tiny Robo and Lesser Mazinger.
 * My Nayme Is: 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.
 * Mythology Gag: Often very subtle, and sometimes a Crowning Moment of Awesome.
 * Example: In the forums-only story 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 Deep Space Nine; the mention is a joking reference to the accusations that the concepts behind Star Trek: Deep Space Nine were stolen from an early presentation about Babylon 5 made by J. Michael Straczynski 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.
 * A Mythology Is True: The Vikings had it right.  Every other culture's religion, human or otherwise, is either completely off-base or a set of "skins" laid over the Norse gods.  For instance, the Kilrathi god of war, Sivar, is just a different face of Tyr Grimjaws.
 * Named Weapons: Most of the Cool Swords, especially in Symphony of the Sword, are named. Liza Shustal even instructs Juniper on the importance of named weapons.
 * Names to Run Away From Really Fast
 * Myron Dween. At first you think, oh, that's kind of an Embarrassing First Name, Mostly Harmless. But then you realize: this guy is Funkotroni, and is a total square. Something is definitely wrong here,.
 * Darth Venger (as is traditional for a Sith Lord)
 * Akio Ohtori, but only if you get the connection from the anime that.
 * Next Gen Fic: The Symphony of the Sword and Warriors of the Outer Rim story cycles are about the Author Avatars' children and their friends.
 * Never Bring a Knife to A Gun Fight: "Overstreet's First Law of Tactics", stated, restated and expanded throughout the stories. First, from The Quagmire Project:

"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."
 * In Symphony of the Sword:

"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."
 * Then, "Gryphon's Expansion of Overstreet's Law of Tactics":

"If all else fails, bomb the planet."
 * Followed by "Matrix Dragon's Expansion of Gryphon's Expansion":

"And if all else fails, bring your friendly neighbourhood God."
 * And finally, "Julzz' Commentary":

"That was actually the script written by a film student in Olympus before the Olympus Fall/Earth Alliance Restructuring before the War of Corporate Occupation. Inexplicably, it got made into a made-for-TV movie, hence the major historical inaccuracies. It sometimes turns up on the late-late-late-late-night movie channel in various broadcast zones."
 * NGO Superpower: Many, including GENOM, the Wedge Defense Force, and the International Police Organization.
 * Nice Hat: 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.
 * No Bisexuals: Averted in the Future Imperfect era -- there are several in the primary cast of Symphony of the Sword.
 * No OSHA Compliance: Lampshaded in Road Trip to Naboo Part 4.
 * Noodle Incident: 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.
 * Nothing Is Scarier: 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 Evil Plan coming to fruition, but it sure was creepy anyway.
 * Not a Date: Corwin and Utena go on many of these before they wise up.
 * Not Me This Time: 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!
 * Obfuscating Stupidity: Prince Garon of Gamilon, Devlin Carter to a lesser degree.
 * Old Shame: 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.
 * One Steve Limit: Being a fusion of so many stories, violating this was inevitable. We have two machine intelligences, EVE and Eve. Eiko Rose and Eiko Kageshoujo were both originally named Girl A in Japanese. But the strangest has to be two Anakins, Anakin Skywalker and Anakyn shar Atrados, who were split from the same source character at different ages and given radically different backgrounds.
 * One World Order: Ruthlessly enacted by EarthGov during the period covered by the later installments of Symphony Of The Sword.
 * Only Known by Their Nickname: MegaZone.
 * Organic Technology: Jyuraian spaceships.
 * Our Elves Are Better: Most of them are actually minor Celestial beings native to the lower heavens (Alfheim and Svartalfheim), akin to but less powerful than angels. Hyeruulian elves are believed to be the descendants of "colonists" who moved to Midgard.
 * Out, Damned Spot!: Marty Rose, in Dies Irae.
 * Patchwork Fic: 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 X-Men who now coexist in the UF universe.
 * Phlebotinum Rebel: Scott Bernard.
 * Physical God: 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.
 * Pillar of Light: A permanent pillar emanates from Odin's palace in Asgard.
 * Planet of Hats
 * Planetville: Some are imported whole from source material; others, native to the setting, are 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.
 * Pleasure Planet: Disney's World
 * Plot-Relevant Age-Up: Vigdis.
 * Polyamory: Practiced by a good contingent of the cast, with a notable exception being Martin Rose. The Symphony cast are still wearing their Rose Seals years after the tournament ended, and they still represent engagement rings to Anthy even if she is married to Utena.
 * Post Modernism: As a Mega Crossover in a Science Fantasy setting, this is to be expected, but it goes far beyond that. Incorporating the entire storyline of Revolutionary Girl Utena certainly helps, providing plenty of Deconstruction, metatropes, and shadow girls. But even from the very first story, what is theoretically a Self-Insert Fic has real people vastly outnumbering the three fictional anime characters; by the end of the Core, it's also a Meta Fic In Space. See the entry on Genre Busting above.
 * The Power of Rock: 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.
 * Pregnant Badass: Anthy, in assorted stories released between 2003 and 2013.
 * Proud Warrior Race Guy: Well, besides the Klingons, several different varieties.
 * Psycho Serum: Several have been mentioned over the years, but one we see in use is "Comet", a drug which boosts firebenders well past Sozin's Comet levels (hence its name).  As of the Fifth Symphony, it's starting to appear in Republic City on Dìqiú.
 * Punch Clock Villain: The Big Fire accountants forced into being field agents by their Q-Boss, Earl, in The Antianeira Incident.
 * Rape as Drama: Well-handled: Both Kaitlyn and Utena have rapes in their backstories -- Kaitlyn's more violent than Utena's Mind Screw 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 Big Damn Heroes.
 * , too. Which contributes to her eventually going Yandere and doing it to.
 * Raygun Gothic: 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.
 * Real Life Writes the Plot: At one remove, maybe -- Sumire's self-exile from the Hanagumi in the backstory of Aegis Florea 2 seems to reflect Michie Tomizawa's retirement from Sakura Taisen, 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.
 * Real Person Fic: Other than the Author Avatars 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
 * 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 Myth Busters and the Teutuls of American Chopper. 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.
 * Nikola Tesla is regarded as one of the greatest inventors in Galactic history, to the point that he tutored Skuld.
 * Redemption Equals Death: So, so averted. Most Atoners end up working with the good guys.
 * Reference Overdosed: Just check out the Sources section on this page if you have any doubts.
 * Remember When You Blew Up a Sun?: Oh so many.
 * Retcon: As the creative team's skills increased over the years, there have been retcons both large and small of earlier details.
 * Core 4 (Crossroads) did a Cosmic Retcon, where many fictional things became fully integrated into reality, and the self-inserts lost awareness of how their reality seemed to be based on 20th Century fiction.
 * Exodus Climber, a three-part forums-only story released in January 2014, seamlessly Retconned GENOM's Invid mecha from a variety of boomer-based robots to a biomorphic race exploited by GENOM.
 * An early story, Altered Appleseed, was binned during a reorganiztion of arcs and their component stories in 2014. According to EPU staff member Phil Moyer, there was an in-universe explanation for its existence:

"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 Get Carter fame (Edison and 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 Randolph Carter of Boston (1874-1932?). 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."
 * 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 Cybertron Dreams, now known as Cybertron Reloaded, and the epic "Day of Infamy".
 * Rewriting Reality: Everything starts with the program CLULess, which materializes both the Lovely Angels and Largo -- along with a load of Powered Armor and Mecha-Mooks. Eventually we discover that it even remade the entire UF-verse into the Patchwork Fic universe we know and love.
 * Rich Bitch: Again, Liza Broadbank before her Heel Face Turn; again, her sister Clarissa has this too.
 * Rich Idiot With No Day Job: Subverted by Prince Garon of Gamilon, who is using Obfuscating Stupidity 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.
 * Robot Girl
 * Robot War
 * Roboteching: Used as a verb from the first story on.
 * Rouge Angles of Satin: Deliberate invocation in Last Transport, to demonstrate Kid Flash's rather spastic -- and unintentionally funny -- typing style.
 * Rule of Cool: Everything. It's the editorial prime directive.
 * Running Gag: "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 Word of God:

- Gryphon, 3 December 2011

""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 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.""
 * Sadist Teacher: Professor Aaron Harris at WPI.
 * Santa Claus: By the beginning of Azalynn's Winter Holiday, Saionji (after having been trounced by Kaitlyn) had 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 was a hallucination or not, and notes that he wasn't a good enough boy that year to get a present from Father Christmas.
 * Scary Dogmatic Aliens: The Covenant, most of the Kilrathi.
 * Scary Shiny Glasses: Kaitlyn when she confronts Garcia in Hunter Rose.
 * Science Fantasy: UF qualifies in every conceivable way by mixing Sci Fi and Fantasy almost seamlessly.
 * Sci-Fi Writers Have No Sense of Scale: 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:

""Upotte!! with airplanes". The cast appeared to consist mainly of personified World War II fighter aircraft (with character traits inspired by quirks of the aircraft, in the style of the gun girls of Upotte!!), who attend various rival high schools and do aerial battle (at the controls of, erm, "themselves", Arpeggio-like) for interscholastic prestige (à la Girls und Panzer)."
 * Sdrawkcab Name: The realm of Oriphos, which occupies the cosmological mirror-opposite position to Cephiro.
 * Self-Insert Fic: And how! Practically the Ur Example. 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.
 * Sex Face Turn: Saionji's "rehabilitation" via having sex with Azalynn.
 * Shadow Archetype
 * Shining City: New Avalon
 * Shout-Out: See the Shout-Out section, above.
 * Show Within a Show: Many, including the Battlecruiser Vengeance franchise (a long-running Klingon TV show/movie property with many different films and sequel series), The Adventures of Red Lad, the Crimson Lizard series of movies, Avalon Chopper, Dalek 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" 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.)
 * Of particular interest as of late summer 2014 is Fly Girls!, an entire anime/manga series being created out of wholecloth by the EPU Forum members in a strange, interactive semi-roleplay manner. Inspired by a dream he had, Gryphon described it as


 * Posters on the EPU forum began creating the "canon" for Fly Girls! by spontaneously discussing their "memories" of their favorite episodes, characters and moments in the show and/or manga (and movies, and OVAs), which are slowly being accumulated into a single comprehensive document.

""... 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."
 * Single Biome Planet: Lampshaded by "Ice Planet Halloran V" -- yes, that's what it's officially called.
 * Slash Fic: 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 Foe Yay slash fans shipping Largo and Gryphon, much to the latter's disgust.
 * Snowball Lie: Cthia -- see Fake Band, above.
 * Something About a Rose: 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 Captain Picard in a Rose Duel is definitely Rule of Cool.
 * Song Fic: Pretty much any story with a performance by the Art of Noise in it turns into this for a while.
 * Space Opera
 * Space Western: 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 Halo.
 * Speech Impediment: Kaitlyn Hutchins, with various subversions -- her stutter vanishes when speaking with Marty Rose or, and . As is not uncommon in the real world, it also vanishes when she sings.
 * Epileptic Trees: Could Kaitlyn's stutter have been caused by being exposed to NeuroKill in utero during Days of Miracle and Wonder?
 * Spin-Off: (Gryphon and Zoner Get) Hopelessly Lost, now being recreated as Bubblegum Crisis: The Iron Age.
 * Star-Crossed Lovers: Gryphon and Tali from Star-Crossed, natch.
 * Stealth Hi Bye: Megazone is always doing this accidentally, and he doesn't understand why.  Or how:  he's a big, hulking guy wearning a big black coat and usually has a shaved head -- he's not exactly easy to overlook.
 * Stealthy Colossus: Megazone; see Stealth Hi Bye above.
 * 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.
 * Subspace Ansible
 * Subspace or Hyperspace: Both and more. (See FTL Travel, above.)
 * Succession Crisis: Instability in Cephiro drives a lot of the action in Symphony of the Sword.
 * Superhero
 * Superhero Paradox: The Ultramen left Earth in the 20th century when they realized they were actually attracting the giant monsters they were ostensibly defending the Earth from.
 * Super Registration Act
 * Take That:

"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."
 * Tannhauser Gate: Played with in chapter six of Cybertron Reloaded:

""Blind we are," 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.""
 * Terraform
 * That Man Is Dead: Liza Broadbank, after watching her life come crashing down around her and rebuilding it from scratch, renames herself Liza Shustal.
 * Theme Naming: The world, cities and nations of Ishiyama -- the planet where the local version of Sakura Taisen took place -- are named for members of the Sakura Taisen production team. Other planets often have names appropriate to their "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.
 * Theme Tune Cameo: Occasionally pieces of music from various soundtracks show up in the story as "native" compositions -- for instance, "Scarlet no Gakuen" from Revolutionary Girl Utena became a piece Kaitlyn wrote for her school orchestra, inspired by Utena.
 * This Is a Drill
 * This Is Not a Drill
 * This Is Something He's Got to Do Himself: 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.
 * Those Wacky Nazis: Still lurking about in the 25th century, and led by the Red Skull.
 * Time to Unlock More True Potential
 * Time Travel: With at least four Time Lords and their TARDISes, not to mention other methods, it's almost casual.
 * There Is Only One Bed: 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.
 * To the Pain: 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.
 * Transformation Sequence: The Rune Knights; also, in Knights of the Tenth World, Part 3: Endgame, Utena undergoes at least three involuntary transformation sequences in less than 15 minutes.
 * Trapped in Another World: 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.
 * True Art Is Incomprehensible: Satirized with Ragulin of the Ecole Musico-Technologique and his pretentiously avant-garde "l'Experience Sonique" in The Rose that Blooms in the City of Light; further mocked by Ragulin himself much later, after.
 * Turing Test: Administered by the Turing Institute on the planet Turing III. Artificial Intelligences that pass this test are certified as sentient beings in the United Federation of Planets. However, applications have to be submitted by their owners, which given the strong Androids Are People, Too nature of the setting, many of the characters view it as a form of slavery.
 * The "Unicorn In The Garden" Rule: Everything that's happened and been written in the UF universe since 1991 ultimately traces right back to the discovery of the HoloDecStation and CLULESS in the first Core story.
 * Unto Us a Son and Daughter Are Born: 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.
 * Velvet Revolution: The Tau Ceti revolution was relatively short-lived; after the planet's Psi Corps were cleaned up, Earth Alliance more or less wrote off the colony. The expectation was, however, that neither side was ready for a galactic civil war quite yet, but the war was indeed coming.
 * Virtual Soundtrack: In virtually every EPU piece longer than a short-short since the late 90s.
 * Voice of the Resistance: Network 23, Big Time TV, and even the BBC! Trope Namer Susan Ivanova doesn't broadcast; she likely has her hands full dealing with Derek Bacon, her CO on B6.
 * The War of Earthly Aggression: GENOM, Earthforce, etc. want to take over Known Space. Earth is usually not on the side of the good guys in UF.
 * Warrior Heaven: Valhalla, natch.
 * Warrior Prince: Actually "hard-coded" into the nature of Cephiro, where he acts as a roving "correction mechanism". Examples include Dios and ultimately.
 * Wave Motion Gun: Several varieties, from several sources, including the Trope Namer from Uchuu Senkan Yamato.
 * What Measure Is a Non-Human?: Instead of a hidden moral value, it can actually be measured in terms of Spengler flux. ACIs run a wide range from barely sentient to emitting three times the Spengler radiation of average humans.
 * Wham! Episode: Hunted Rose
 * Wham! Line


 * Who Wants to Live Forever?: 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 is revealed to have, as a result of a combination of this Trope, Victory Is Boring and, spent the previous forty years in the throes of a Heroic BSOD until  reboots her with a What the Hell, Hero?/"The Reason You Suck" Speech that is so scathing and insulting that she cannot help but to rouse from her self-imposed emotional stupor and get angry.
 * Whole-Plot Reference: Part of the plot to Fulcrum of Fate, Part IV, including Master Corto, is an extended reference to Apocalypse Now.
 * With Great Power Comes Great Insanity: One of the side effects of most of the Psycho Serums that appear in the setting, most notably "Comet".
 * Wolverine Claws: 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.
 * The Worcester Fireball: See Doomed Hometown above.
 * World Tree: Yggdrasil, the original ash tree.
 * World-Healing Wave: When the Cephiran Trinity revolutionizes the world of Cephiro. It doesn't bring all the good guys back to life, since that would kind of defeat the MKR plot, but most of the world's physical damage is fixed.
 * Worthy Opponent: Hans von Hammer of Big Fire, at least to Biggles and Kozue Kaoru. (And vice-versa.)
 * Write Who You Know: To the point that all but three of the many characters in the first story are real people.
 * You Already Changed the Past: Time Travel in UF mostly works in this way, from 's literal Self-Fulfilling Prophecy to Doc Mui having to go back and save himself in the past. But then there are more Timey-Wimey Ball moments where characters go back in time to Set Right What Once Went Wrong before fading away into non-existence (though that was apparently orchestrated by resident deus ex machinist Edison Bell).
 * You Kill It, You Bought It: Akio kills Zagato and takes his place as High Priest of Cephiro.
 * You Mean "Xmas": 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.) As Gryphon put it succinctly in the EPU forums on 13 August 2014, "The UF universe in the 25th century is the future of the past."

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 Kei (...and Skuld, and Sumire Kanzaki, and ...)
 * Megazone and Yuri
 * Rob Shannon and Ayeka
 * Redneck and Wasyuu
 * Hammer and Eiko
 * This is not just about 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.
 * 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).
 * After her revival and introduction to the "Big Universe" beyond Dìqiú (and a subsequent improvement in her sanity), Azula spent at least some of her teenage years as the drummer in a girl-garage band called "Discarded Weapons" with Laura Kinney (who plays bass guitar).
 * Here, Read This. Derek Bacon's interminable series of advice and self-help books for the person in an unusual situation is well past Running Gag territory and turning into a trope. A few confirmed titles:
 * So You Just Arrived from a Parallel Dimension
 * So You Aren't the Master Race: Coping with the End of Your Civilization's Dreams of Conquest
 * So You Became Unstuck in Time
 * So You're Not Who You Thought You Were: Coping With Manchurian Deprogramming
 * So You've Adopted A Kilrathi
 * So You've Just Crawled Out of a Vault: Surviving in a Post-Apocalyptic World
 * So You Fell From A Great Height: A Celestial Outcast's Survival Guide to the Mortal Plane
 * So You Are Falling from a Great Height (Which is, according to Word of God, 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
 * So You Escaped the Robot Apocalypse
 * So You Got Shot
 * So You Come From Ye 17th Centurie (co-written with Samuel Pepys)
 * 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.
 * So You're Batshit: A Survival Guide to Mental Instability, written not by Derek Bacon but by Wade Wilson.

Shustal!
