* In the ''Franchise/MassEffect'' {{self insert fic}} ''FanFic/MassVexations'', AuthorAvatar Art goes through pretty much the entire fic noting the events of the game as they go on. He ends up lampshading just about everything he notices, including making an offhand comment about one of the game's PlayingWithSyringes examples.
* ''Fanfic/DoingItRightThisTime'': The people hiding together with Shinji in the shelter know how the “HumongousMecha versus {{Robeast}}/{{Kaiju}}” thing works:
-->''"The military must've hit the Angel with something big," a man in NERV uniform replied. "Either an N2 mine or a fuel-air explosive."''\\
''"Never works in the movies," a third voice muttered.''\\
''There was another, longer vibration. "And that," the NERV employee continued with a proud grin, "is the secret anti-kaiju weapon that will work!"''
* Several characters in ''[[Fanfic/TotalDramaComebackSeries Total Drama Battlegrounds]],'' though [[TheAtoner Heather]] deserves special mention after seeing [[CheerfulChild Rodney]] die in one of the virtual reality challenges:
-->"But see, in every movie that's science-fiction or fantasy or the like, [[InfantImmortality the kid always makes it]]. This time [[SubvertedTrope he didn't]], and thus, this queen has broken the unwritten rule for such movies. Even an [[IKnowKarate Asian martial artist cliché]] or the [[AmericaSavesTheDay American commando cliché]] cannot defeat someone who is breaking the unwritten rules. But as I said, I didn't want to say this out loud, or [[ClosetGeek I'd look weird]]."
* ''Fanfic/{{Luminosity}}'': Bella realizes that her life is a RomanceNovel. Relying on her status as the protagonist may be part of why she makes some risky decisions.
* In ''FanFic/HarryPotterAndTheMethodsOfRationality'', Eliezer's characters are frequently utilizing their knowledge of fiction tropes, although each character is savvy in only a few genres.
** When [=McGonagall=] tells Harry what really happened to his parents (Harry had been raised by his aunt and her husband with no explanation), Harry starts asking her which plot hooks might be left dangling, frequently making analogies to ''Literature/TheLordOfTheRings''.
** Hermione does frame events around her as if she were in a story (early on, she wants [[WrongGenreSavvy a romance between her and Harry]]), but she's more often seen trying to convince Harry that he isn't in a story, and that he should stop trying.
** Draco likes to compare his own behaviour to the heroes in the opera/play performances that his father takes him to see.
** Daphne Greengrass, like most of the girls, views events like a romance plot, and tries to invoke her own romance with Neville during one of the battles between the first-year armies.
** Dumbledore likes to frame himself as the wizard Gandalf from ''Literature/TheLordOfTheRings'', and conversations between him and students are often framed in "young heroes" and "mysterious old wizard" terms.
** Quirrel and Harry often discuss the finer points of how to manipulate others, referencing stories and contrasting them with reality as they do so. "The role people play" is an element of Eliezer's writing that comes out frequently in this character.
* ''Fanfic/CalvinAndHobbesTheSeries'' has the titular duo, though in different ways: Calvin knows a lot about sci-fi movies.
* Arcanus in the ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' fanfic ''FanFic/{{Whispers}}'' is stated in-universe to have become this by reading a lot. He demonstrates it by [[LampshadeHanging lampshading]] a case of InnocentInnuendo.
* ''Fanfic/ChildrenOfTime'' has [[WesternAnimation/SherlockHolmesInTheTwentySecondCentury Beth Lestrade]] is quite firmly OneOfUs, an obsessive Sherlockian and a [[{{Fangirl}} geek]] for several more fandoms, with a habit of making [[FandomNod Fandom Nods]] and inducing Holmes to deliver a few [[TakeThat Take Thats]].
* Captain Kanril Eleya of ''Fanfic/{{Bait and Switch|STO}}'' and related ''VideoGame/StarTrekOnline'' fics displays flashes of this on occasion. In the side story [[https://www.fanfiction.net/s/10371318/1/An-Anomalous-Nightmare "An Anomalous Nightmare"]], she rapidly makes the connection between the strange behavior of her crew and the NegativeSpaceWedgie the USS ''Bajor'' is stuck in.
--> "And the connection to that grav anomaly is?" [[TheMedic Warragul]] gives me a funny look and I scoff at him. "Oh, come on, we all know that's where this is headed. Every time we or anyone else hit an unexplained anomaly like this in the past it's made ''something'' weird happen."
** Part of the explanation is, she's a fan of TurnOfTheMillennium Earth science fiction (although not ''Franchise/StarTrek'' because [[CelebrityParadox that would be silly]]).
* In the ''Series/BuffyTheVampireSlayer'' / ''ComicBook/PowerGirl'' fan fic story ''FanFic/OriginStory'', Xander Harris was a comic book geek. Alexandra Harris has all of his memories. She is thus often able to predict what the various Marvel Comics heroes will do before they think of doing it.
* Due to his fondness for videogames (especially [=RPGs=]), Literature/HarryPotter is quick to spot important plot points in ''[[https://www.fanfiction.net/s/11669575/5/For-Love-of-Magic For Love of Magic]]'', such as referring to Hagrid's mention of "You-Know-What in Vault 713" as being a "side quest note", correctly guessing there was a prophecy regarding himself and Voldemort, and figuring out Voldemort has a SoulJar.
