* In ''Fanfic/UnmaskerUnleased'', there are various hints that Marinette is actually Ladybug, but Cat Noir never connects the dots. The red domino mask and ribbons in her pigtails when she becomes Unmasker, which has an effect on him. How natural Unmasker is able to swing around with her vines. Being able to anticipate his moves. Her flirtatious and playful behavior, and use of calling him [[AffectionateNickname Kitty]]. Luka's vagueness on Ladybug needing to stay hidden. Unmasker/Marinette's several near [[FreudianSlip Freudian Slips]]. To be fair Cat Noir is very focused on trying to get through to Marinette and Ladybug did a good job in fooling him back in ''[[Recap/MiraculousLadybugS03E14Kwamibuster Kwamibuster]]'' by making him see Ladybug and Marinette as separate people.

* Buffy basically accuses the rest of Angel Investigations as having done this in ''[[http://offline.buffy.de/outlink_en.php?module=/webserver/offline/www.destructo-girl.com/reads/fanfiction/nockels-deb/letterriley01.htm A Letter to Riley]]''; they spent weeks watching Angel become increasingly obsessed with Darla and never suspected there was anything 'unnatural' about it, and yet Giles deduced that Angel was under a spell after talking with him for just an hour when he hadn't even seen Angel in over a year.

* A moment of this kicks off ''Fanfic/CrumblingDown'', as Lila attempts to kill Ladybug by pushing a wall onto her and then [[EvilGloating gloats about it]], unaware that Alya saw and [[CaughtOnTape filmed the whole thing]].

** It's been over a year since Princess Luna's return; Moondancer's known ''something'' was off about the night sky, but didn't realize that the image of the Mare in the Moon was gone from its usual spot until Princess Celestia pointed it out. Moondancer herself is surprised she didn't realize this sooner and chalks it up to being preoccupied by wallowing in her own misery.

* In ''Fanfic/OSMUFanfictionFriction'', Oscar is teleported from the Shower Room of Precinct 13579 to the Lab and doesn't notice because he's too busy talking to Oswald. Likewise, Oren and Owen are also unaware they're teleported to the Lab. Oswald averts the trope because he's the only one who ''is'' aware of where he is, and begins having a NakedFreakOut.

* In ''[[Fanfic/RateThis Rate This (Trust Is Hard to Come By]]', Lila ''does'' see the dark red -51 floating over her head while checking her vanity. But she [[UnusuallyUninterestingSight dismisses this]] as just another oddity caused by some random akuma, without considering what it might mean. She also fails to notice everybody she passes by on her way to school reacting with shock and disgust, blissfully unaware that the number indicates just how much Ladybug ''despises'' her [[CelebrityLie self-declared "best friend"]]. By the time she finally learns what's going on, it's far too late.

* In ''[[https://unmaskedagain.tumblr.com/post/189474563797/rate-this-trust-is-hard-to-come-by Rate This (Trust is Hard to Come By)]]'', Lila ''does'' see the dark red -51 floating over her head while checking her vanity. But she [[UnusuallyUninterestingSight dismisses this]] as just another oddity caused by some random akuma, without considering what it might mean. She also fails to notice everybody she passes by on her way to school reacting with shock and disgust, blissfully unaware that the number indicates just how much Ladybug ''despises'' her [[CelebrityLie self-declared "best friend"]]. By the time she finally learns what's going on, it's far too late.

* ''[[https://archiveofourown.org/works/29579046/chapters/72699462 A Little Knowledge Is A Dangerous Thing]]'': After hitting Izuku hard enough to severely injure his spine, accidentally crippling him, All Might chides Katsuki for sending up a distress flare, failing to notice his successor is currently sprawled right next to Katsuki in a growing puddle of his own blood. He then attacks Katsuki, only stopping when he finally notices Izuku and [[MyGodWhatHaveIDone realizes what happened]].

* PlayedForDrama in ''Fanfic/AmazingFantasy''. In her rush to meet up with Martin to participate a raid on a Demons hideout, Melissa [[spoiler:neglected to insert the last two screws of the electric eel cage, which allowed it to shatter and electrocute Max]].

* In ''Fanfic/DragonsButterfliesAndWhoKnowsWhatElse'', Mirabel and Hiccup manage to get all but one of the donkeys when trying to round them all up, that donkey accidentally destroys the entire stock of china in a china-shop. This gives Alma an excuse to show Mirabel that she can't be relied on, treating this one misstep (including the fact that she had to use a machine to accomplish this) as though it invalidates everything else.

* In ''Fanfic/KimberlyTsGargoyles'', when gargoyles of the New Orleans clan initially invite the Manhattan Clan for a holiday, Elisa and Fox initially assumes that the New Orleans gargoyles consider the entire clan unmated because they aren't acknowledging her bond with Goliath, but Goliath soon clarifies that the New Orleans gargoyles just hadn't [[TheNoseKnows registered his scent marker yet]]. At this point, the only members of the New Orleans clan to have met the Manhattan Clan were Adam and Rebecca, and Adam's half-human status means he has a poor sense of smell while Rebecca had been fawning over Brooklyn so much that Goliath observed he wasn't sure Rebecca had even noticed his ''color'', never mind his scent. Goliath later admits that he fell victim to a similar oversight when he met the Avalon clan, reflecting that in hindsight he was already subconsciously aware of his feelings for Elisa by the time he met this clan and so didn't pay attention to their scents as he wasn't looking for another mate.

** When Umbridge tries to arrest Remus for not informing the Ministry of his lycanthropy, Frank Longbottom informs her that Remus had registered his condition with the Ministry back in 1980, and that she can't arrest Remus simply because no one at the Ministry bothered to check his files.

* In ''[[https://archiveofourown.org/works/17733968 the art of living lies and letting go]]'', Marinette's and Adrien's identities are exposed early on. After a few months of the city freaking out, everything largely goes back to normal, except sometimes Marinette and Adrien get out of tests by pointing out that they were too busy saving the city to study. However, Lila still pretends to be Ladybug's best friend.

* In ''[[https://archiveofourown.org/works/22799041 Blessed]]'', Lila decides that the best way to deal with her critics Marinette and Nathaniel is to slander them both by claiming she witnessed Nathaniel threatening Marinette, forcing her to stay in a romantic relationship with him. This causes everyone to [[LiarRevealed realize she's a liar]] -- because here, the two aren't just [[RelatedInTheAdaptation siblings]], but [[RelativeError fraternal twins]]. Yet she failed to pick up on the fact they ''had the same last name''.
* This bites Chat Noir in the backside in ''Fanfic/BurningBridgesBuildingConfidence''. When Cole sees him [[AchillesInHisTent sitting on the sidelines]] and watching Ladybug fight alone, he blithely informs her that he's not ''going'' to help... not until Ladybug [[EntitledToHaveYou agrees to start dating him]]. He fails to notice that Master Fu is in the same alleyway, and is less than pleased by his BetrayalByInaction.

* A moment of this kicks off ''Fanfic/CrumblingDown'', as Lila attempts to kill Ladybug by pushing a wall onto her and then [[EvilGloating gloats about it]], unaware that Alya saw and filmed the whole thing.

* Throughout ''Fanfic/TheKarmaOfLies'', Adrien plays TheCharmer, fully expecting others to be swayed by his smile and reassuring claims. He's so used to glossing over and dismissing the negative feelings of others -- especially Marinette[=/=]Ladybug -- that he fails to pick up on how badly his usual tactics are failing. A perfect example of this is during the live interview, where he doesn't notice how unwelcome he is or how his behavior is [[NotHelpingYourCase turning the crowd against him]] until they start [[WhatTheHellHero calling him out]].
* ''Fanfic/OhYouDontHaveToDoThatCommunication'': An akumatized Lila disguises herself as Marinette as part of a plan to ruin her reputation; however, she gets exposed as an imposter, knocked out and cured. Upon reawakening, she doesn't notice that she's back to her normal form and attempts to continue the plan, unintentionally revealing her true nature to everyone else, since she's no longer able to claim that she's BrainwashedAndCrazy.

** During their Heroes vs. Villains exercise, Katsuki is able to distract the other team so well that they completely miss Ochako floating through a window and making her way towards the bomb.

* In ''Fanfic/{{About Last Night|MyLittlePony}}'', Pinkie Pie, who knows all details about all her friends, doesn't recognize Rarity's double is not her.

** It's been over a year since Princess Luna's return; Moondancer's known ''something'' was off about the night sky, but didn't realize that the image of the Mare in the Moon was gone from its usual spot until Princess Celestia pointed it out. Moondancer herself is surprised she didn't realize this sooner, and chalks it up to being preoccupied by wallowing in her own misery.

** [[spoiler:In the same chapter, it's noted that Neighsay's captors missed his teleportation pendant, and that it still has magic. He intends to use this to his advantage.]]

* ''Fanfic/TheEchoRemainsButTheSongIsNotTheSame'': While Team Eight is helping an elderly couple move, one of their clients remarks that they've chosen a smaller apartment since their children don't live with them anymore. Sakura is about to ask what happened before Chouji stops her, silently drawing her attention to a memorial alter that she hadn't noticed.

** In Act II, after fighting off a vampire agent in Ashton City, Moka fails to realize several obvious things (the agent's [[FightingFingerprint fighting style]], personal knowledge of Moka, and voice over the radio) that prove the agent's identity as her sister Akua, even [[GenreBlindness dismissing the odd coincidence]] that Akua and Kahlua just ''happened'' to show up at Yokai Academy right after the gang returned there from Ashton City. It isn't until Act III chapter 42, where the group discovers from Hokuto that Akua and Kahlua lied and Fairy Tale is not only still active, but coming to Yokai Academy for a full-scale attack, that Moka puts it together; she promptly {{lampshade|Hanging}}s how blind she was to ''not'' have put it together beforehand.

* “[[https://www.fanfiction.net/s/12638414/1/Pokemon-Dark-Multiverse Pokemon: Dark Multiverse]]” has a rare example of Franchise/{{Batman}} doing this when Bruce Wayne finds himself in the [[Anime/PokemonTheSeries Pokemon world]] and wonders why his Dark Knight counterparts are after Dawn and Serena as he can’t find anything that might connect them, not asking the right questions for them to realise that Dawn and Serena have a friend in common.
* Probably an excusable oversight as he doesn’t spend much time with Rogue whatever side they’re both on, but in ''Fanfic/SpiderX'', Lance didn’t realise that Rogue was now able to touch people again for over a week before he officially ‘defected’ to live at the mansion, and only realised things had changed when he saw Scott without his glasses (the power nullifier Peter had developed for Rogue being adapted for Scott and Jamie).

* Buffy basically accuses the rest of Angel Investigations as having done this in ''[[http://offline.buffy.de/outlink_en.php?module=/webserver/offline/www.destructo-girl.com/reads/fanfiction/nockels-deb/letterriley01.htm A Letter to Riley]]; they spent weeks watching Angel become increasingly obsessed with Darla and never suspected there was anything 'unnatural' about it, and yet Giles deduced that Angel was under a spell after talking with him for just an hour when he hadn't even seen Angel in over a year.

* In ''FanFic/TheBoyWhoDiedALot'', Madam Hooch refuses to entertain the notion that the bludgers have been sabotaged, insisting that nothing can get past her wands.
* ''Fanfic/TheChosenSix'';

* In ''[[https://archiveofourown.org/works/17733968 the art of living lies and letting go,]]'' Marinette's and Adrien's identities are exposed early on. After a few months of the city freaking out, everything largely goes back to normal, except sometimes Marinette and Adrien get out of tests by pointing out that they were too busy saving the city to study. However, Lila still pretends to be Ladybug's best friend.

* This bites Chat Noir in the backside in ''FanFic/BurningBridgesBuildingConfidence''. When Cole sees him [[AchillesInHisTent sitting on the sidelines]] and watching Ladybug fight alone, he blithely informs her that he's not ''going'' to help... not until Ladybug [[EntitledToHaveYou agrees to start dating him]]. He fails to notice that Master Fu is in the same alleyway, and is less than pleased by his BetrayalByInaction.

* ''FanFic/RosarioVampireBrightestDarkness'':

* This is one of Olive's character traits in ''Fanfic/AFrozenFlower''. As Oprah notes, "Olive could be so wrapped up in something, she couldn't see what was right under her nose", shown when the agent pops out of the park's tube entrance and doesn't notice that the park is completely annihilated until after Oprah tells her to look at her surroundings. Even when Olive ''does'' notice, the first question she asks is if the damage was caused by a tornado and not if it was Orchid's (the actual culprit's) doing.

* ''[[Fanfic/CheshireMiraculousLadybug Cheshire]]'': When returning from Alix's birthday party, Marinette fails to register just how many Miraculi she's wearing. Namely, that she wound up with [[spoiler:four: Plagg, Kaalki, Lirii and ''Pollen'']].

* ''[[Fanfic/TheWolvesInTheWoodsMiraculousLadybug The Wolves in the Woods]]'': After Strikeback is dealt with, Ladybug is in such shock over how the akuma was taken down that she fails to notice [[spoiler:her room isn't unoccupied when she returns]]. As a result, [[spoiler:Ms. Diamandis learns her secret identity]].

* In ''[[Fanfic/AboutLastNightMyLittlePony About Last Night]]'', Pinkie Pie, who knows all details about all her friends, doesn't recognize Rarity's double is not her.

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

* PlayedForDrama in ''Webcomic/StevenUniverseGoneWrong''. After racing to the beach house, Greg's relieved to see his son seemingly none the worse for wear, other than seeming pinker than usual. He fails to notice [[spoiler:his son's body]] lying on the couch, leading to mounting tension as it gradually dawns upon him that something's wrong.

* ''Fanfic/FeralnetteAUBigFatBreak'': During the denouncement of ''Even a Worm Will Turn'', Adrien fails to notice the DeathGlare his father is giving him as he embraces Felix. [[spoiler:Gabriel himself fails to notice that his conference call with Amelie is still running, meaning she witnesses and calls him out on giving both boys such a withering look.]]

** Dib does this twice in the first chapter — first, when he overlooks the Big Red Button on the Spittle Runner's console, and later when he's trying to escape Norlock's castle and doesn't see a nearby window right away.
** In Episode 2, Dib is keeping an eye out for Zim at the Parent Teacher conference, and yet Zim's whole group sneaks up behind him.
** At the start of Episode 4, Zim and Skoodge somehow fail to notice [[CanisMajor Phil]] in the same room as them, despite his size.
** In Episode 7, when Dib and Steve are hiking through the woods to reach the unburied Meekrob ship, they completely miss a dirt road leading right there. Though Dib comments it wasn't on the map, so it's not entirely their fault.
** Also in Episode 7, Zim fails to notice Dib and Steve's presence in the Children of the Bright and Shining Saucer camp, until they speak up.
** In Episode 16, Team Save Earth fail to notice the monster army attacking the city until Mortos points it out to them.
