* In the ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' fanfic ''[[Fanfic/CodePonyEvolution Code: Pony Evolution]]'', Pinkie Pie's normal forth wall breaking is taken UpToEleven by breaking not only the fourth wall of the "show" but ''the fourth wall of the fanfic '''as well'''''
* In the ''WesternAnimation/TotalDramaIsland'' fanfic ''FanFic/TotalSiblingRivalry'', after the author's self-insertion, Chris wonders about buying a new fourth wall.
* In the Hetalia fanfic ''Fanfic/ItsASmallWorldAfterAll'', the characters warn each other not to break the Fourth Wall often so that [[TheFourthWallWillNotProtectYou the fangirls reading the story (including the author) can't get in]]. However, a lot of the characters (usually Japan) end up breaking the Fourth Wall in the middle of the story (via looking up at the ceiling and [[WhoWritesThisCrap complaining to the author]]) and cause a war in the author's note over 'keeping the Fourth Wall up'. Fangirls [[NoKillLikeOverkill obliterate]] the Fourth Wall and take over the fanfic for a chapter, after which everyone agrees on inserting a [[SlidingScaleOfFourthWallHardness Fourth Wall with a door.]]
* In the ''Literature/CastawaysOfTheFlyingDutchman'' fanfic ''[[http://www.fanfiction.net/s/4900100/1/A_Spoof_from_the_Castaways_of_the_Flying_Dutchman A Spoof from the Castaways of the Flying Dutchman]]'', the author spoofs the story in an entertaining way using SelfInsert and brutally honest--sometimes exaggerated or downright made up--ways of depicting the events occurring, all the while beating the shit out of the fourth wall as they move the story along.
-->'''Ben:''' Oh look, a note! (Reads note) Oh fun, I get to sneak out tomorrow. Maybe something interesting will happen in this story.
-->'''Me:''' You mean like a faster update? Like that will ever happen.
* A common source of humour in the ''FanFic/TamersForeverSeries''; often it's the author doing the forth wall breaking with random comments.
* In the ''StarWars''/''WesternAnimation/VeggieTales'' crossover ''FanFic/LarryBoyAndTheLittleManOfPurpleness'', the trailer ends with these lines:
-->'''Han:''' Excuse me as I break character here: To the author: About this dialogue, are you on some form of illegal substance?\\
'''Wedge:''' And could we please have some?
** [[NeverTrustATrailer In context]], however, Han's only breaking the fourth wall in a play they're rehearsing.
* In chapter 6 of the ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' fanfic ''Fanfic/TheMonsterMash'', this is played for a mixture of drama and dark comedy with side orders of GoMadFromTheRevelation and HumansAreCthulhu.
** Pinkie Pie breaking the fourth wall to acknowledge or even directly address the readers and/or the author is something of a RunningGag in [=FiM=] fanfiction in general. Sometimes other characters get in on the act, more often it's waved off as her [[CloudCuckooLander just being Pinkie]].
* In ''Film/TheLastAirbender'' parody ''[[FanFic/BringMeAllYourElderly Bring Me All Your Elderly]]'', the [[WesternAnimation/AvatarTheLastAirbender Animated!Characters]] not only are aware that they are animated (and discuss it very casually), they also leave the Animated!Universe to enter the Movie!Universe, generally blame all unexplained events either on the [[WhoWritesThisCrap fanfic author]] or Creator/MNightShyamalan, read their own fanfic and comments straight off the internet, and basically suffer severe existential crises as a result. The fourth wall itself actually makes a brief appearance at one point in the story, along with a sign that says "fragile."
-->'''Mai:''' But for future reference, guys - try to be careful about breaking the fourth wall around Zuko, okay? He doesn't know, and it tends to freak him out a little.
-->'''Zuko:''' Fourth wall? What wall? Someone broke a wall?
-->'''Mai:''' Nothing, Zuko. Just don't worry about it.
* Happens often in the ''FanFic/CalvinAtCamp'' series, especially when [[TheHauntedMansion the Hitchhiking Ghosts]] are involved.
* ''Fanfic/SweetiesMansion'': Pinkie Pie still has this ability even as a [[BrainwashedAndCrazy brainwashed]] ghost that is out to kill Sweetie Belle. [[spoiler:Upon catching her, Sweetie gains this ability as well and unintentionally calls the author out for the direction the story is going when she's in LotusEaterMachine.]]
* In Chapter 13 of Part 2 in ''FanFic/ClashOfTheElements'', after giving a eulogy to [[spoiler: Smithy, Dimentio mentions to the audience about how he will "satisfy their desire for entertainment.]] Of course, [[{{FridgeHorror}} when one takes into consideration his powers]] and that beyond the computer screen [[{{FridgeBrilliance}} would probably qualify]] [[{{OhCrap}} as another dimension for him...]]
* Utilized by ''FanFic/AdventCrossoverCrisis''; the author gets [[MarvelComics SheHulk and DeadPool]], two renowned fourth wall breakers, to address the audience directly in the opening to explain the fic in greater detail.
* ''WebAnimation/TurnaboutStorm'': [[WesternAnimation/MyLittlePonyFriendshipIsMagic Pinkie Pie]] gets a few of these moments, as it's usually done with her. She even [[ReadingAheadInTheScript had read some of the script beforehand]] to have an idea of what to do while investigating.
* At the end of ''FanFic/PaperMarioX 2: The Thousand Year Door'', [[Franchise/TheLegendOfZelda Link]] puts out a velved box out of his bag. Inside includes a ring which he uses to propose to Zelda. The very last line is Link addressing to the audience: "Can you guess what I'm going to do?"
* ''Fanfic/ImperfectMetamorphosis'': In a rare totally serious example, [[PhysicalGod Yukari]] inadvertently weaponizes this against [[spoiler: [[EldritchAbomination Yuuka]]]] when she reaches into her soul and generally rips things apart. [[spoiler: This leads to Yuuka periodically taking over the narration and speaking directly to the reader, as well as adjusting her myriad plans to manipulate the established narrative.]]
** The first hint towards this comes in a memorable MadnessMantra ("It can't be. Just words on a page. It's all paper. And not even real paper.") which [[spoiler: Yuuka]] keeps muttering to herself while ignoring being pummelled into the dust by Yukari.
* The ''Blog/ReadingRainbowverse'' has as its central concept the idea that various ponies are commenting on comics and answering questions. That's not this trope. What is this trope is when a reader pointed out to Gilda her blog had been hijacked by a mysterious "mod" person, resulting in the two having a bit of a tussle.
* ''FanFic/ANewOrder'': Helios does this when speaking with the ghost of Queen Serenity. He and she both know the secret of the Time Gates (him because he read her mind) but he asks her to explain it anyway because the people on the fourth wall don't know.
* In the ''Manga/MedakaBox'' fanfic ''Fanfic/WorldAsMyth'', Misogi Kumagawa recognizes when bold font and italics are used in dialogue.
** Anshin'in seems to be aware of the events of the original manga.
* Like the source material, the ''{{Manga/Bleach}}'' fanfics ''[[https://www.fanfiction.net/s/6902577/1/Phases-of-the-Moon Phases of the Moon]]'' and ''[[https://www.fanfiction.net/s/8222340/1/Chasing-the-Moon Chasing the Moon]]'' have [[{{Omake}} Omakes]] at the end of each chapter. These omakes leave the FourthWall fairly intact. However, in the companion fic ''[[https://www.fanfiction.net/s/10332014/1/The-Trials-of-Kurosaki-Karin The Trials of Kurosaki Karin]]'', the omakes involve [[OriginalCharacter Original Characters]] [[ThoseTwoGuys Masaryu and]] [[EnsembleDarkhorse Kohaku]] breaking the Fourth Wall with impunity as they discuss the events of the story and interact with the audience ''Arrancar Encyclopedia'' style.
