* ''Fanfic/BringerOfDeath'' is first a ''DragonballZ'' fic, and second an attempt to [[DoingInTheWizard plausibly explain the physics of DBZ.]] The result is an epic story that appeals to fans [[WillingSuspensionOfDisbelief unwilling to suspend their disbelief]] in poorly-explained spaceship mechanics, etc.
* [[http://www.fimfiction.net/story/73406/rainbow-in-the-dark The writer of]] ''FanFic/RainbowInTheDark'' uses this as a TitleDrop of the ArcWords to a good effect of this trope.
* The ''Film/BackToTheFuture'' fanfic ''[[http://www.fanfiction.net/s/3993367/1/The_Almanac_Chronicles The Almanac Chronicles]]'' is accurate with respect to geography, as well as history from 1958 to [[spoiler: November 22, 1963, when President John F. Kennedy is ''not'' assassinated [[ForWantOfANail due to a side effect of Biff's fortunes]] ]].
* The fanfic ''[[http://www.fanfiction.net/s/3210906/1/The_Butterfly_Effect_0 The Butterfly Effect 0]]'', based on the [[Film/TheButterflyEffect film]], is accurate with respect to southern New York state geography as well as historical events.
* [[http://www.fimfiction.net/user/kalash93 Kalash93]] puts A LOT of effort and research into his stories. The greatest examples of this so far are the [[http://www.fimfiction.net/story/81159/1/racer-and-the-geek/predawn gun porn and detail about the military equipment]] in ''FanFic/RacerAndTheGeek, and the high levels of realism and detail put into the military aspects of [[http://www.fimfiction.net/story/90939/1/shell-shock/the-tower Shell Shock.]] His erotic pieces greatly avert YouFailSexEdForever. He isn't very fond of using artistic license for anything.
* A lot of details went into the researching behind the locations, schools and universities that appear in the ''TsubasaReservoirChronicle'' [[AlternateUniverseFic real-world AU]] [[http://tvtropes.org/pmwiki/pmwiki.php/FanFic/Freefall Freefall]], as well as [[spoiler: the symptoms of leukaemia, which a main character is diagnosed with early in the plotline.]]
* Half of ''FanFic/HuntingTheUnicorn'' is a CerebusRetcon of [[{{Glee}} Blaine's]] RelationshipSue and KnightInShiningArmor portrayal. The other half is [[DeconstructionFic showing what it would take to produce someone like Blaine.]] Given that the author is studying psychology and read up on medieval chivalry, it isn't surprising that some readers find it so believable.
* The author of ''FanFic/HogyokuExMachina'' asked her high school readers if they could define tuberculosis without using Wikipedia to determine if Ichigo and friends would reasonably know.
** She even checked if ''{{House}}'' airs in Japan to justify Ishida watching the show.
* Fanfic/TheWizardInTheShadows is notable for having lots of accurate throw away references to the Earlier ages of Middle Earth.
* In the ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' fanfiction {{Fanfic/Silent Knight}}, Nightfyre's flightsuit puts constant pressure on her limbs, ensuring proper blood-flow to the brain during stressful maneuvers. This is the same way real life flightsuits work for jet and fighter pilots.
** In the same chapter, Ash Coat notes some materials on the [[spoiler: human sword]] that genuinely act as absurdly sharp material when treated correctly; it's suggested that some {{Applied Phlebotinum}} is employed to sustain this condition.
* Cornova did a lot of research with regards to the ins and outs of the Anime/{{Pokemon}} anime for PokeWars.
** A prime example is how he included an entire chapter on Kaiza, a character from an episode of ''{{Anime/Pokemon}}'' that never made it out of Japan.
** Also, numerous one-shot characters (Duplica, Yas and Kas Gyms, AJ, etc.) are portrayed perfectly in character.
* The author behind ''Fanfic/{{XSGCOM}}'' has an author's notes section after every chapter, where he/she explains from ''exactly'' where in the original works every character, plot-twist and gadget in the chapter came. He does the same for ''Fanfic/HuntedTribes'' and ''Fanfic/NewCaliforniaDreaming''.
* The ''WesternAnimation/TotalDrama'' fanfic writer, Tropers/{{Gideoncrawle}} shows his work [[SignatureStyle routinely]]. In his first story, ''Fanfic/{{Legacy}}'', this is most apparent in the [[DescriptionPorn details]] related to the victim's wound. His later stories have substantial Notes sections that explain the more obscure allusions, among other things.
** His Season 1 reimagining story, ''Fanfic/TheLegendOfTotalDramaIsland'' tends to show his work in-story for such things as inventive solutions to certain problems, and the effects and treatment of hypothermia.
* [=GreenSonic21=], the author of ''FanFic/SonicGenerationsFriendshipIsTimeless'', has clearly done plenty of research on not only pretty much all of the Sonic games, but also [[Anime/SonicX the]] {{WesternAnimation/Sonic|SatAM}} [[WesternAnimation/TheAdventuresOfSonicTheHedgehog cartoons]] and [[ComicBook/SonicTheComic comic]] [[ComicBook/SonicTheHedgehog books]], and it clearly shows. He's even referenced events from [[ComicBook/MyLittlePonyFriendshipIsMagicIDW the FiM comic books]] into the story.
* In most of the ''[[FanFic/NewLookSeries New Look Series]]'' the author, ShinnokRaiden99 has well-conceived characterizations for its main characters and a healthy amount of mythology gags.
* One of the reasons the ''Webcomic/{{Homestuck}}'' fan blog ''FanFic/{{Brainbent}}'' is so popular with fans is because of how accurately and sympathetically it portrays people with mental health issues (except John, who's [[AmbiguousDisorder disorder is unspecified]]). In particular, Autistic readers really like the non-stereotyped portrayal of Autism.
* ''FanFic/FriendshipIsOptimal'' has a lot of accurate science, and the author has clearly done a lot of research on artificial intelligence and philosophy.
** The RecursiveFanfiction ''FanFic/FriendshipIsOptimalAlwaysSayNo'' similarly shows this, with military and medical details being accurately depicted.
* ''[[http://www.potionsandsnitches.net/fanfiction/viewstory.php?sid=2660 Different, Not Defective]]'' features a well-researched and sensitive portrayal of an autistic {{Harry Potter}}.
* FanFic/DividedRainbow, which contains lots of links to phenomenon such as moonbows and lunar phases.
* Aaron12, author of the ''WesternAnimation/DannyPhantom'' fanfic series, ''FanFic/FacingTheFutureSeries'' takes his time research the cartoon, picking up obscure details and other things to avoid {{Continuity Snarl}}s. It only helps to make the series more popular.
