* 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'''''
* ''Fanfic/TheChildOfLove'': In chapter seventh's omake, Asuka berates the author because he is lazy and hasn't updated his website.
* ''Fanfic/SOE2LoneHeirOfKrypton'': The characters frequently break the fourth wall in the omakes: the author and Asuka talk about his discarded ideas, Asuka complains of a thug breaking the fourth wall when he accused her of doing blatant shout-outs, Shinji gets a present of the author, or the author decides to address the characters.
* 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 [[Franchise/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.
* Fanfic/TheIronHorseEverythingsBetterWithRobots has [[WesternAnimation/MyLittlePonyFriendshipIsMagic Pinkie Pie and Discord]] both make reference to things that only happened in the [[ComicBook/MyLittlePonyFriendshipIsMagicIDW comics]]. When questioned about it, they give the same reply:
--->'''Pinkie Pie/Discord''': Itís canon to the comics, donít worry about it.
* At the end of ''FanFic/PaperMarioX 2: The Thousand Year Door'', [[Franchise/TheLegendOfZelda Link]] puts out a velvet 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.
* Sweetie Belle does that in the beginning of WebComic/MoodyMarkCrusaders.
* In ''FanFic/{{Amber Night and the Curse of the Diabolical Pastry Thief}}'', a ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' fanfic, Amber Night is apparently no stranger to the "sadistic hairless chimpanzee pounding away it the keyboard that controls the fate of the pastryless pony" on the other side of the fourth wall, demonstrated in the beginning when she grows inspired by his monologue without having heard it, and again later on when she [[spoiler:convinces him to disable the gym's laser defense systems]].
* Super Smash Bros fanfiction ''FanFic/TenRandomCharacters'' suffers varied degrees of abuse from the characters, and often, the author. It is broken so frequently that the wall is given a codename, the Norfair Alley. Sometimes, this trope is quite literal. Taken [[UpToEleven Up to Eleven]] in [[spoiler:Chapter 11, in which a mob of fangirls invades after the fourth wall quite literally falls down dead]].
* ''[[https://www.fanfiction.net/s/6125021/6/The-Staircase-Time-Froze The Staircase Time Froze]]'':
-->'''Ginny:''' (thinking) ''I can't believe that was only yesterday. It seems like one day lasted several chapters for no particular reason.''
* The original Fanfic/DantesNightAtFreddys was no slouch when it came to LeaningOnTheFourthWall, but its sequel, ''Animatronic Boogaloo'' went so insane that, around chapter 8 and especially in chapter 9, the author describes the events as, "Dante and [[spoiler:MJTR]] destroy the fourth wall, take it around back, and beat it with its own body."
* In Fanfic/NewReality, Mithos jumps into the real world to kidnap the heroine, making it an In-Universe example.
* In the CrackFic ''[[https://www.fanfiction.net/s/9500873/1/There-s-Someone-Else There's Someone Else]]'', Tira remarks that she's been taunting Patroklos "throughout the whole [[VideoGame/SoulSeries game]]".
* Team Rocket occasionally pulls this off in the ''Franchise/{{Pokemon}}'' fanfic ''FanFic/ThePowerThatsInside''.
-->'''Jessie''': What could we even use this thing as, a cannon?\\
'''James''': None of this is canon, Jessie.
* In the [=MST=] treatment of ''FanFic/TomSwiftAndHisWarTank,'' Joel and the bots become so frustrated at Ned's stupidity that they run out of ways to riff him and are forced to ask the readers for help.
* Fan game ''VideoGame/RakenzarnTales'' has two primary offenders: Axel Akamura, an OC who's implied to be from outside of Rakenzarn like Kyuu, and Deadpool himself, who even does his own special skill descriptions.
* Much like [[WesternAnimation/{{Beetlejuice}} the cartoon]] on which they're based, ''FanFic/{{Cinderjuice}}'' and its sequel take any number of shots at the fourth wall. One reviewer asked whether the fourth wall had killed the author's father, since it gets shattered with so much frequency.
* In the ''House'' fanfic "Iggy Pop Go The Zombies" a literal piece of wall collapses when another character tells House, "Quit making that face, you look like Bertie Wooster."
* The ''Franchise/{{Metroid}}''-''Franchise/{{Kamen Rider}}'' crossover fic, ''[[https://www.fanfiction.net/s/11772125/1/Metroid-Kamen-Rider-Generations-Full-Series Metroid: Kamen Rider Generations]]'', has such examples.
** Stage 7, the ''Series/{{Kamen Rider Drive}}'' tribute chapter shows [[spoiler:Shinnosuke's shocking expression when Samus wakes up in the Drive Pit as he and the others attempt to forcibly dissect her Fusion Suit, he says while bringing up his series' main writer, "Is it just me or was the writer fond of police dramas?!"]]
** Stage 17, where Samus, Takatora, Mitsuzane, and Go confront a [[BackFromTheDead resurrected Kaito Kumon]], after they transformed, the song "Supernova" from ''Series/{{Kamen Rider Kiva}}'' plays, leading Go to tell the writer the music is inappropriate, much to Takatora's annoyance.
--->'''Go:''' HEEEYYY! This is NOT Kamen Rider Kiva! Why bother play ''that'' damn music?!
--->'''Takatora:''' Jesus Christ! Eyes on the battlefield, Shijima-kun! Who are you talking to, anyway?
--->'''Go:''' It's the writer! Nah, whatever.
