* ''Fanfic/BlackbirdArrow'': When Thea freeloads onto Oliver's plane trip to the Himalayas and sees Sara there with him, she initially believes they're trying to hook up again. At this point, [[ShipSinking the last person Oliver wants to be in a relationship with is Sara]].

* In ''[[https://www.fanfiction.net/s/10552763/1/A-Courage-s-Flame A Courage's Flame]]'', the firebender Daisuke, [[AmnesiacHero who can't remember anything but her old name]], is believed by Katara to a girl from the Fire Nation that lived before the 100-year-war just like Aang, since she and Sokka found the two in the remains of the same iceberg. Daisuke, or rather [[Anime/DigimonAdventure02 Daisuke Motomiya]], is from modern-day Earth, having lost her memories and acquired Firebending when she was sent to the Avatar world.

* ''[[https://archiveofourown.org/works/44837788 SCP-136: The Cheese Gremlin]]'' is about the Website/SCPFoundation encounting Plagg the kwami from ''WesternAnimation/MiraculousLadybug'' after he ate a cargo truck worth of cheese. At one point, Plagg tries to refer to a close companion but it always comes out as bubbles. Since the Foundation knows he is a God of Destruction, they belive that he is speaking about an EldritchAbomination with the bubbles [[StarfishLanguage being its actual name]]. He's actually trying to refer to his weilder Adrien, [[{{Geas}} but he is under a spell keeping him from exposing his identity to strangers]].

** Ladybug is initially convinced that the Akuma Wicked Witch is Chloé, due to the latter's volatile nature and having been just been publicly humiliated and effectively disowned by [[AbusiveParent her mother Audrey]]. When she and Chat Noir find Chloé, they discover that she was akumatized into Little Red, a skittish BrokenBird that sees the Witch as her sole protector. The Wicked Witch is actually Alix, who became akumatized out of anger upon learning what happened to Chloé: Ladybug is at a loss as to why Alix would care so much about the school AlphaBitch's feelings, unaware that the two are close friends on the cusp of dating, much less that [[MutualMasquerade Alix and Chloé are witch and familiar]].
* In [[https://nobodyfamousposts.tumblr.com/post/734443964533489664/what-if-adrien-rejection-in-felix-culpa this story]], Marinette [[InternalReveal reveals]] to the rest of their class that Adrien had previously told her that he ''knew'' Lila was decieving everyone, but insisted that "So long as both you and I know the truth, does it really matter?" Alya, Nino and the others swiftly draw the conclusion that Adrien pretended he was on her side in order to [[ManipulativeBastard manipulate her]]... because he knew Lila wasn't ''actually'' a liar. So they're RightForTheWrongReasons, and Adrien finds himself condemned for being a BitchInSheepsClothing while Lila gets to continue PlayingTheVictimCard.

* ''[[http://cartoon.adult-fanfiction.org/story.php?no=600095039 How I Learned to Love the Wild Horse]]:''
** All over the place in regards to [[WesternAnimation/TotallySpies WOOHP's]] conclusions concerning [[Anime/RanmaOneHalf Ranma Saotome]]. They believe he's the leader of a terrorist organization known as the Nerima Wrecking Crew and has come to America for some nefarious purpose, as opposed to trying to escape the shenanigans in Nerima. After getting to third base with him, Clover is convinced that Kodachi is Ranma's psychotic ex-girlfriend who made him go down on her but told him he sucked so she didn't have to return the favor. In reality, Ranma just experimented in his girl form.
** Of course, Ranma makes several false assumptions as well, partially due to thinking his violent UnwantedHarem, HilariouslyAbusiveChildhood, and terrible friends are the norm.

* In ''Fanfic/ASmallButStubbornFire'', Marinette tells her mother that Gabriel and Nathalie must be having some secret fling as they disappear to dark corners, not knowing that Gabriel is Hawk Moth and Nathalie is his loyal follower.

** When Kyoko demands [[SerialKiller Suzembachi]] to tell her why she's kidnapped so many young girls, Suzembachi shoots back it's [[NotSoDifferentRemark the same thing Kyoko does]]. Kyoko takes this to mean she captures young girls to directly feed to Familiars in order to grow new Witches for Grief Seeds, which causes Kyoko to swear off Familiar farming entirely just so she can stop any such comparisons in her mind. What Suzembachi actually meant is that she's cultivating new Witches directly by manipulating vulnerable young girls into becoming Magical Girls, then forcing them to Witch Out and harvest their Grief Seeds, but Kyoko not knowing of the true nature of the link between Magical Girls and Witches doesn't even consider this possibility.

[[folder: Crossovers]]

* ''Fanfic/LeaveForMendeleiev'': [[MisplacedKindergartenTeacher Miss Bustier]] worries that transferring into [[SternTeacher Ms. Mendeleiev]]'s class has been hard on Marinette, as she can tell that Marinette's tense when she visits her classroom to help her father give a baking lesson. What she doesn't realize is that Marinette has been ''thriving'' in her new class, having gotten away from her long-time bully and being protected from her by Mendeleiev -- unlike Bustier herself, who pressured Marinette to 'take the high road' and 'set a good example' by enduring Chloe's cruelty. She's not tense because of anything her new teacher did, but because she's returned to a tense environment... one that's gained a reputation for being 'the Akuma Classroom' due to how many akuma have been born from Chloe's unchecked antics.

* In ''WebComic/ScarletLady'', Hawkmoth sees how she hangs back and avoids engaging "The Bubbler" and [[VillainRespect praises her strategy]], believing that she was protecting her Miraculous. In reality, Scarlet just... didn't ''care'' about the Bubbler threatening to send all the guests into the atmosphere.

** After overhearing Alix complain about the full moon and torn clothes, as well as realizing she's starting to smell like wet dog, Juleka becomes convinced that she's also a supernatural being and is a werewolf, and tells the others so that they can spy on her. While correct that she's part of the magical world, Alix is actually a witch. It's Chloe, who happened to be around during those moments, that's the werewolf. Alix was the one complaining because she's the one Chloe entrusts to make sure she doesn't cause any damage when in a feral full moon state.

[[AC:''Manga/MyHeroAcademia'']]

* ''FanFic/ChangingGears'': Aizawa knows that Shoto is only using half of his Quirk but the boy's burn scar causes him to assume the boy has to be careful not to burn himself or others when using the fire half. In reality, Shoto was burned by his mother when she had a psychotic break and he refuses to use his fire to spite his abusive father.

* Similarly, [[http://deusexequus.deviantart.com/art/Rarity-s-Case-638467736 "Rarity's Case"]], a fanart of Recap/MyLittlePonyFriendshipIsMagicS6E22PPOVPonyPointOfView, has Twilight misunderstanding Rarity's scream of "How did I get all these crabs?!"

[[AC:''Anime/{{Naruto}}'']]

* In ''[[https://www.fanfiction.net/s/8073686/4/LATE-Naruto-Life-After-The-Ends LATE Naruto]]'' Sasuke puzzles through Naruto's suddenly more impressive skills, his unrealistic knowledge of others, and the teachers dislike of him and comes to the conclusion Naruto is a full-fledged shinobi sent by the Hokage to keep an eye on the class that's full of clan heirs. His knowledge and skills are due to having several years of being a shinobi under his belt. The teachers' dislike of him is because they don't want a shinobi infiltrating their class. Even Naruto's poor grades and frequent absences can be explained as being bored with classes he's already taken. In reality, Naruto's [[PeggySue from a year in the future]] and everything else comes from being the Kyuubi Jinchuuriki.
* For a brief time in ''[[https://forums.spacebattles.com/threads/orochimama-naruto-si.858340/page-17#post-68282818 Orochimama]]'', Kakashi believed the woman who resembles a female Orochimaru is someone trying to frame the Sannin somehow, thinking that Orochimaru could easily pass himself off as a woman and wouldn't make such an amateur mistake as to just look like himself genderswapped.

* In ''[[https://www.fanfiction.net/s/10759250/6/Unbiased Unbiased]]'', Sasuke learns that Naruto is a jinchuuriki and puzzles out that Madara controlled the Kyuubi via the sharingan after obtaining his brother's eyes. Between that and knowing Itachi is after Naruto, he thinks Itachi wants Sasuke to obtain Mangekyo so he can steal his eyes and control the Kyuubi.

* In ''[[Fanfic/WhatYouKneadNaruto What You Knead]]'', after meeting Kakashi and Naruto telling them he owned a bakery and had been in the reserves for the last few years (which usually doesn’t happen until shinobi are in their forties), Sasuke and Sakura assume their new teacher is half blind, pushing fifty, and out of shape. Kakashi notes that they’ll need to work on what they assume, since in the field it could have gotten them killed.
* ''[[Fanfic/AWrinkleInTimeNaruto A Wrinkle in Time]]'' has many people assume numerous, logical reasons as to why Naruto, Shikamaru, and Lee are so skilled. The three, obviously unwilling to divulge that they're actually from ten years in the future, end up running with most of it.

[[AC:''Anime/NeonGenesisEvangelion'']]

[[AC:''Anime/OnePiece'']]

* ''Fanfic/PokemonMysteryDungeonLostTracksOfTime'': Several characters note how caring Sneasler is of rescuer newcomers Ingo and Emmet. She goes out of her way to help them, understands their train lingo, and even mimics their pointing habits and speeches. On top of this, Ingo and Emmet are both Sneasels, and Ingo is even the same variant that can evolve into a Sneasler. The common assumption is that Ingo and Emmet are her younger brothers. Sneasler denies the claim, but neither Ingo nor Emmet do at any point.

** A possibly invoked example in the Gladion Interlude: Gladion's Umbreon tries to point his trainer to a group of girls in swimsuits playing at a beach. Gladion then comments that Umbreon would prefer him to peek on them rather than reading his [[PornWithPlot Alphanegan Chronicles]]. Umbreon was actually trying to tell him that his sister Lillie was one of them, [[FailedASpotCheck but he slips up and nods]], [[DelayedReaction and then realizes what Gladion said]]. Cue FacePalm.

[[AC:''Anime/PuellaMagiMadokaMagica'']]
* ''[[https://archiveofourown.org/works/32241079/chapters/79905451 Heartstrings]]'' (Registered users only)

** When this Homura later meets up with Mami under different circumstances and demonstrates her skill level to her and makes mention of her years of experience as a magical girl while leaving out that she's a time traveler Mami, who craves companionship and sees things that she doesn't know in Homura's skills, assumes that Homura is older than her. This is then followed by Mami asking Homura to be her sempai, which flummoxes Homura and leads to an ongoing joke after it is clarified about 'Homura-Sensei'

* ''[[https://archiveofourown.org/works/47869699/chapters/120683302 Plan 47]]'' Madoka and Sayaka, while reading into Homura's strange mixture of warnings, hesitations, and odd reaction to affection that comes as a result of her TimeLoopFatigue and come to the completely logical conclusion..that Homura is being mind controlled and her abrupt adjustments, as a result of the aforementioned plan 47's reactions being unexpected are a result of her trying to fight off the mind control and warn them.

* ''Fanfic/TheSoulmateTimeline:''
** When trying to figure out the nature of a SharedDream she had with Homura which featured the aftermath of a battle with Walpurgisnacht, Madoka and Mami come to the conclusion that Homura has battled a Walpurgisnacht multiple times...because she is incredibly unlucky and that her odd behavior comes from having lived through two [[HeroKiller Walpurgisnacht]] battles where she was the sole survivor. Being a time traveler fighting the same Walpurgisnacht again and again doesn't cross either of their minds.

* In ''[[https://www.fanfiction.net/s/12986165/4/A-Monster-s-Marriage A Monster's Marriage]]'', Roman Torchwick believes that Jaune Arc is a crime boss who has managed to become ''the'' major player in the criminal underworld when he wasn't paying attention, since Jaune has managed to be connected to and well-liked by almost every other high-ranking criminal in the city. In reality, Jaune is an oblivious NiceGuy who befriended these criminals through [[VillainsOutShopping rather mundane means]] or through his wife Cinder, who ''is'' technically a crime boss. In fact, [[LockedOutOfTheLoop Jaune is unaware that most of his friends and acquaintances are villains]] for most of the story.

* ''[[https://archiveofourown.org/works/8249843/chapters/18904520 at least it was here]]'': When Jaune walks into the kitchen without a shirt on, everyone sees that he has a long line of hickies along his chest. Since everyone ([[ObliviousToLove except Jaune]]) knows that Pyrrha is in love with him, they angrily order him to put a shirt on, hoping Pyrrha won't notice. They are unaware that [[FriendsWithBenefits Pyrrha was the one who gave him the hickies]]. As an extension of this, both Jaune and Pyrrha are convinced that the other isn't interested in dating and refuse to even bring up the idea out of fear of ruining their friendship, while everyone else (''especially'' [[ShipperOnDeck Nora]]) wonder when they'll get their act together.

** ''FanFic/ProfessorArc'' and its sequel ''FanFic/HeadmasterArc'': The story is the result of Jaune becoming a professor at Beacon as [[GoneHorriblyRight his falsified credentials have made him seem too experienced to be a student]]. Much of the humor and plot is drawn from people making wrong assumptions based off his supposed expertise. Even [[spoiler:Cinder]], one of the few to realize that Jaune's credentials are falsified, draws the conclusion that [[spoiler:he's likewise a criminal with an agenda. She is ''technically'' correct in that his falsified credentials are illegal, and he ''has'' an agenda -- it's just that it's nowhere near what she thinks it is]].
** ''[[Fanfic/WhiteSheepRWBY White Sheep]]'':

** More PlayedForDrama here, but in ''Fanfic/RelicOfTheFuture'' Jaune is believed to be a descendant of the Ashari, instead of a time traveler, by both Salem and Ozpin. They still think he's an invaluable asset to their respective sides of the ForeverWar, but they could not be more wrong about his origins.

* In ''Fanfic/GreyjoyAllaBreve'', Tywin is murdered by someone using Petyr Baelish's own knife - which he had lost a few moments before the murder took place. Given his enmity with Varys the Spider, several comments made and Tyrion's (who has been taken prisoner by the North and has a legendary hatred of his father) friendship with Varys and dislike of Baelish, the latter comes up to the logically sound conclusion that Varys and Tyrion have made an alliance to kill Tywin Lannister and frame him, thus getting rid of an enemy and allowing Tyrion to claim Casterly Rock. Unfortunately, [[spoiler:the real killer is [[LittleMissBadass Arya Stark]], who was Tywin's cupbearer without Tywin knowing her real identity: she stole Baelish's knife without him noticing and then took advantage of being alone with Tywin to kill the man - and then Sandor Clegane helped her to erase the few existing clues so she is not found out.]]

* In ''Fanfic/PadawansReturn'', when Ahsoka Tano from the time of the Empire finds herself in the past during the events of ''Film/ThePhantomMenace'', she immediately becomes concerned at anything that might lead to Palpatine become interested in Anakin's potential in the Force even before events lead to her becoming Anakin's new Master. However, this is because she believes that Palpatine killed Anakin in her future, as she was sent back before becoming aware that Anakin survived to become Darth Vader.

* In ''[[FanFic/{{Internship}} Deputy]]'' Taylor correctly deduces that Amy is gay and then ''incorrectly'' deduces Carol is a homophobe who mistakenly thinks Taylor is trying to seduce Amy. Amy finds this very amusing as Carol actually thinks Taylor will seduce Amy into ''villainy''. Much later Danny, based on a conversation with Carol, comes to a very similar conclusion as Taylor.

* ''Fanfic/PoundTheTable'': J. Jonah Jameson has long since clued into the fact that the teenage freelancer Peter Parker doesn't just ''happen'' to be able to get good pictures of Spider-Man when no one else can. After all, his staff has experience reporting and photographing in everything from natural disasters to active warzones, and they can't get a single good picture of him, so there's no way a random teenager can without there being ''something'' more to it. The conclusion he comes to, however, is that Spider-Man is blackmailing a desperate teenager into being his personal photographer to better aid in his GlorySeeker ways. Consequently, [[spoiler:Jonah has been quietly stowing away all the royalties Peter has been unknowingly earning for his photography into a trust fund to be paid out when he turns eighteen, so he can "get away from that menace."]]

* ''Fanfic/TheAmazingSpiderLuzInAcrossTheOwlVerse'': After the battle with [[TheDreaded Ingrimaxus]] and seeing Luz's contribution to it, Belos comes to the conclusion that Luz is in fact a human-witch hybrid and Eda's daughter, believing her to be a unique being that could potentially come about by the mating of witches and humans. Lilith, who knows enough about Luz to know that's not even remotely true, is noticeably dumbstruck as to how he could have possibly come to this conclusion and takes it as further confirmation that Belos [[NotSoOmniscient is full of shit]].

* In ''Fanfic/OnceMoreWithFeeling'', Misato believes Kaji is peering at her cleavage when he's merely checking if she's still wearing her cross necklace. Kaji humorously notes she predictably leapt "to the wrong -but perfectly understandable- conclusion".

** Ladybug is initially convinced that the Akuma Wicked Witch is Chloe, due to the latter's volatile nature and having been just been publicly humiliated and effectively disowned by [[AbusiveParent her mother Audrey]]. When she and Chat Noir find Chloe, they discover that she was akumatized into Little Red, a skittish BrokenBird that sees the Witch as her sole protector. The Wicked Witch is actually Alix, who became akumatized out of anger upon learning what happened to Chloe, though Ladybug is at a lost as to why Alix would care so much about the school AlphaBitch's feelings, unaware that the two are close friends, much less that [[spoiler:[[MutualMasquerade Alix and Chloe are witch and familiar]].]]

* In ''[[http://www.fimfiction.net/story/317629/1/sunset-shimmer-has-crabs/and-theyre-huge Sunset Shimmer Has Crabs]]'', [[ExactlyWhatItSaysOnTheTin said former villain has crabs......]] [[spoiler:the edible, water dwelling kind, infesting her room. Everyone assumes that she has the STD type crab]].

** When Kyoko demands [[SerialKiller Suzembachi]] to tell her why she's kidnapped so many young girls, Suzembachi shoots back it's [[NotSoDifferent the same thing Kyoko does]]. Kyoko takes this to mean she captures young girls to directly feed to Familiars in order to grow new Witches for Grief Seeds, which causes Kyoko to swear off Familiar farming entirely just so she can stop any such comparisons in her mind. What Suzembachi actually meant is that she's cultivating new Witches directly by manipulating vulnerable young girls into becoming Magical Girls, then forcing them to Witch Out and harvest their Grief Seeds, but Kyoko not knowing of the true nature of the link between Magical Girls and Witches doesn't even consider this possibility.
