History LaserGuidedAmnesia / FanWorks

* ''Fanfic/{{Mistakes}}'' depicts the nation-tans ''as unable to disobey a direct order from their human leaders. Thus, [[spoiler:when Japan finds out the horrible things being done to his brothers and his boss tells him to forget about it, not even meaning it entirely literally, Japan ''does'']].

* ''Fanfic/InvaderZimABadThingNeverEnds'': According to Skoodge, for some reason Zim doesn't remember all the bullying that Red and Purple put him through when they were younger, thinking instead that they were always great friends. It's speculated in-unverse that something so traumatic happened that his mind simply blanked it all out and worked around it.

** In ''To Rule Alone, to Build Together'', there's a {{Glamour}} that prevents people outside of Paris from learning about Hawkmoth and his war for the Miraculous in Paris, and also removes their memories of such events when they leave the city. This is demonstrated in a chapter of ''From His Vantage Upon the Moon'' has Princess Shuri, alongside her cousin N'Jadaka and her father T'Chaka, finds out about the Miraculous while in the city for a prosthetic demonstration and get up in an akuma attack when Princess Fragrence goes after Shuri. However, the moment they leave Paris air space, they soon forget about akumas mid-sentence

* ''Fanfic/TheBridge'' gives us Monster X. Other than scattered, almost nightmarish still flashes of a kaiju [[spoiler:heavily implied to be King Ghidorah]] attacking a planet, and some operation being done to stop him, he can't remember a thing prior to a certain point. He even forgot his own name, thus being christened ''X''. This has had no impact on numerous skills he's had, but he can't recall how he learned them. For all intents and purposes, his entire past previous to being the monstrosity he is now is a blank sheet. This leads to him joining the BigBad's forces, after the latter [[DealWithTheDevil promises]] to restore his memories.

[[AC:''WesternAnimation/KungFuPanda'']]

* The ''Franchise/SpiderMan'' fic "[[https://archiveofourown.org/works/49689625/ Jackpot]]" presents Peter and Mary Jane finding a genie in an alternate post-''ComicBook/OneMoreDay'' world where they didn't take Mephisto's deal and Aunt May died, leaving them both on the run from the pro-Registration forces. Peter uses one of his wishes to make this specific wish; " I wish for the world to forget that Peter Parker is Spider-Man, that only MJ and I, and the people that love and care for us, truly love and care for us, will remember that I’m Spider-Man." As the genie confirms, the world still recalls that Spider-Man exposed his identity, but nobody actually remembers it now beyond certain of Peter's friends, and those friends will only confirm their knowledge whenever Peter talks with them.

* ''Fanfic/AFrozenFlower'': This is one of the PsychicPowers that ''lamberos'' have, which they can use to extract specific memories from someone and replace it with chosen memories at their discretion. Oz uses this power in Chapter 4 to convince Oscar that he never tried to kill Orchid nor was he nearly killed by her and that he was asleep at home for the entire night, just before extracting all memories related to the attempted murders.

** When Lux tells her friends in the Demon Realm about her adventures in Amphibia, it's revealed that she doesn't remember [[spoiler:being possessed by the wolf spirit and speaking with the spirit of the Titan]]. This gets subverted once she's informed that [[spoiler:she has two hearts now]]. However, she doesn't recall [[spoiler:them telling her about the other two humans who'd come to the Demon Realm yet]].

* ''Fanfic/TheBridge'' gives us Monster X. Other than scattered, almost nightmarish still flashes of a kaiju [[spoiler: heavily implied to be King Ghidorah]] attacking a planet, and some operation being done to stop him, he can't remember a thing prior to a certain point. He even forgot his own name, thus being christened ''X''. This has had no impact on numerous skills he's had, but he can't recall how he learned them. For all intensive purposes, his entire past previous to being the monstrosity he is now is a blank sheet.

* ''Fanfic/LupineTree'' Has the "Other," a human soul whose memory was damaged in the process of being brought to Equestria. Has type 1 Laser-Guided Amnesia.

* ''Webcomic/SonicTheComicOnline'': Tikal is accidentally [[FishOutOfTemporalWater transported 8000 years into the future]] to the present day. Unfortunately, she remembers [[AndIMustScream being trapped with Chaos for 8 millennia]] in constant fear and pain. To save her sanity Ebony decides to mind-wipe her.
* Adrien reluctantly uses his magic to erase [[spoiler:Marinette's memories of seeing his cat ears and tail through his glamour]] in ''Fanfic/SpellboundLilafly''. He hates himself for it afterward, but Tikki and Plagg quietly approve. It's not permanent, though; the memories are only suppressed, and could eventually bubble back up to the surface.
* In ''[[https://www.fanfiction.net/s/9279403/1/Stuck-in-a-World-of-Fiction Stuck in a World of Fiction]]'' the protagonist's memory is almost completely erased in the process of being sent from the real world to the world of ''Franchise/MassEffect''. It's later revealed [[spoiler: there is more to the memory loss than simply how he got there, as the Reaper's efforts to make him a super soldier included implanting entire other minds and overwriting his own,]] but it still qualifies for this trope as he still remembers every detail of the games, and most of what he'd ever watched in terms of media. His memory is also otherwise perfect, perhaps making this an [[PlayingWithATrope Inverted/Subverted trope]]
* In ''Fanfic/TheStudentPrince'', Merlin uses his magic to wipe Arthur's memory of what happened after [[spoiler:kissing Arthur to [[TrueLovesKiss lift a spell]] and bring him back to his senses]].
* ''Fanfic/ThereWasOnceAnAvengerFromKrypton'':
** It's established by WordOfGod that in this universe, while Asgardians remember that Hela existed, everyone except for Odin has had their memories that she's his true firstborn child erased.
** In ''From His Vantage Upon the Moon'', after Max and Kanjigar defeat a Forever Knight patrol looking for Trollmarket, the Ancient One wipe the Knights' memories of the exact location where the fight happened, thus throwing them off the trail.
* In ''Fanfic/ThisBites'', Cross advises the [[BenevolentConspiracy New World Masons]] to utilize this to prevent people from finding out about the organization. For example, [[spoiler:Tsuru]] had learned a way of using her [[spoiler:Wash-Wash Fruit]] to wipe away memories of anyone who discovers the group, such as Vice Admiral Komei.
* Invoked in ''Fanfic/ThousandShinji'' when Shinji wonders if he can have this to forget the damned [[spoiler:[[OurDemonsAreDifferent Keeper of Secrets]].]]
-->“Yes, that’s part of the same damn debriefing I keep hearing. Incidentally, isn’t there some way to give me laser guided amnesia instead of just wiping out the past three months when we’re done here?”
* Discussed in one chapter of ''Fanfic/TheTwilightChild'', when Twilight Sparkle learns several surprising things about her future all at one, and talks about them with Princess Celestia. In theory, Princess Celestia could erase her memories. Twilight Sparkle asks her if she could, Celestia asks if Twilight wants those memories removed, Twilight asks if she ''would''. Celestia responds with an emphatic "never".
** Actually happens to the main character, over several chapters at the hands of [[spoiler:the Nightmare possessing her]], starting with the memories of her father. She doesn't even notice until she realises she can't remember her father's name.
* ''Fanfic/TwoLetters'': When Marinette retired, she lost all of her memories relating to being Ladybug and the Guardian of the Miracle Box. However, she retained the memories of the ''civilian'' side of her life, along with some WistfulAmnesia regarding her time as a superhero. Luka is particularly worried about how she seemed accustomed to putting everyone else's needs and wants ahead of her own, to the point that he's spent months convincing her that she doesn't have to constantly defer to ''his'' judgment and cater to his every whim.
* ''Fanfic/UniverseFalls'':
** There are [[{{Foreshadowing}} increasingly obvious hints]], starting with the chapter "Gems and Journals", that the Crystal Gems deliberately had their memories of the Author of the Journals erased. "Lost and Found" reveals [[spoiler:''Rose Quartz'' had their memories erased with one of the ray-guns used by the Society of the Blind Eye, and hid their memories in Lion's mane. The Gems are rather distressed when they get their memories back and find out why in the process; in "Chille Tid, Part 2" Garnet reveals to the kids that it was because the Gems were tricked into a deal with [[GreaterScopeVillain Bill Cipher]] and got possessed, and he did... ''[[MindRape something]]'' to them as he was forced out of their bodies]].
** In the three-part Arc 8 finale "Rifts", "Memories", and "Dimensions", [[spoiler:Steven and Dipper are trapped as [[FusionDance Stepper]] after Bill damages Steven's Gem and tricks Stepper into giving up his [[SpellBook shield journal]], which contains all of Steven and Dipper's memories. This means Stepper only remembers things that happened while he was fused, and doesn't remember who Steven and Dipper were or even that he was a fusion in the first place]].
* In ''Fanfic/WhatIfTheYeerksWereTheGoodGuys'', the full members of the Sharing try to introduce a woman to the Yeerks; she freaks out so much that they have to sedate her and use a machine to remove her memories of the past twenty minutes.
* In the ''WesternAnimation/WinxClub'' canon, the Wizards of the Black Circle only wiped Klaus' memories of his wife Morgana, which left a plot hole -- did not anyone notice she was missing? In ''Fanfic/YouWereMyBestFriend'', this is fixed by extending the amnesia laser to everyone who ever met Morgana. Her dance studio passes ownership to one of the instructors, Ms. Matthews, with no one remembering it used to belong to Madame Morgana.
* In ''Fanfic/WeightOfTheWorld'' [[spoiler: Canada's Semblance is revealed to be memory erasure. Before discovering this he accidentally uses it on Russia (to make him forget about Aura), a hotel owner (to stop him from calling the police) America ([[PlayingWithSyringes erasing memories of what Atlas did to them]]), and '''himself'''.]]
* The protagonist of ''Fanfic/WithThisRing'' retains his memory of most DC settings, but has entirely forgotten the ''WesternAnimation/YoungJustice2010'' universe where he arrived. He later discovers that a similar phenomenon has occurred for alternate versions of himself in other universes such as Teen Titans or The Boys; they have each forgotten the specific setting they've landed in.
* PlayedForLaughs in ''Fanfic/ZimTheWarlordIrkenReversion'', as Zim smugly reveals that he erased Dib's memories of the aftermath of "Bolongius Maximus", and that's why Dib can't remember how they reversed their transformation into baloney. It's implied Zim did this just for his own amusement.
