Why, yes, I'd like a piece of your mind.
I'll take this one and that one...

Yuuichi: If you really have amnesia, then how come you said that you were never gonna forgive me?
Makoto: Look, all I do remember is that I have a grudge against you! I just don't remember anything else about my life, ya' got it?!
Yuuichi: I guess I never knew that amnesia could be so convenient.
Kanon

As established elsewhere, amnesia comes up a lot in TV. Amnesia is a funny thing in the real world and can give you lots of strange symptoms.

In TV, it's very weird too, but it's much more specific. Amnesia has several basic attributes in TV land:

1. With surgical precision, amnesia strips you of all information pertaining to personal identity, leaving just about everything else intact. TV Amnesia is a disorder where you forget where you put your keys, but you do not forget what a key is or what it's for. You will forget where you went to school, but not any of the things you learned in school. As a result, the character will retain all of their skills — though they may not know they have them at first.

Interestingly, while this would seem to be Hollywood Science at first glance, this really is how retrograde amnesia works (well, some of the time). "Procedural memory," which governs skills that the brain has automated, appears to be separate from "declarative memory", where you store previous facts and events, and in many cases only one of the two is damaged. And then there's muscle memory, which may or may not be affected by amnesia.

2. In a series with Plausible Deniability, amnesia typically also erases all knowledge of the Masquerade. The character will completely forget that aliens, monsters, vampires and such are real, but will remember that normal people don't believe in such things. This can seem especially odd since, if you don't remember anything, how do you know that aliens and werewolves are any stranger than the sun coming up in the morning and setting at night?note  Even more odd if the character is himself an alien or supernatural being and subsequently "defaults to Muggle" after losing his memory, which is typically the case for those with Alternate Identity Amnesia. Occasionally, this is paired with Fake Memories to create an elaborate deception.

3. With very few exceptions, amnesia is always entirely retrograde: memory loss extends backward from the moment of injury. Anterograde amnesia (the inability to accumulate new memories) has only started to come up in recent years, usually in comedies. Amnesia usually extends back clean to birth. Real amnesia resulting from head trauma or drugs is usually confined to a short period on both sides (before and after) of the incident.note 

4. If a tool of the group the protagonists belong to, the likelihood of abuse of this power is almost never addressed. There's little interest, procedure, or advocacy devoted to making sure someone isn't stealing from, raping, killing or committing other crimes against Muggles and then erasing their memory of it. After all, who cares about Muggles as long as the Masquerade is intact?

5. The amnesia inducer works like a toggle switch (especially in the case of blunt force to the cranium). (Surgeon General's Warning: Definitely NOT Truth in Television.)

Very useful in maintaining that things are No Big Deal. To this end, it's pretty standard for The Men in Black to use this on anyone who's seen too much, often employing a Memory-Wiping Crew. Contrast Exposition Beam. Can cause an Amnesiac Hero to be born.


Examples:

    open/close all folders 

    Anime & Manga 
  • At the end of the first season of the 90s anime adaptation of Sailor Moon, when Usagi mentally wishes to have a normal life, she and the other Inner Sailor Guardians get resurrected, but end up losing their memories of not only being Sailor Guardians, but also of being friends with each other. Luna does not even fix this until the second season, when the Makai Tree Aliens cause trouble in Tokyo.
  • In Pandora Hearts, this is played straight for many of the characters. Gil wishes to know who his master really is, Alice wants to regain her memories of her life before she became a chain, and Oz wants to discover the truth behind his sin. The results are very, very disturbing. Where shall we begin?
    • Ah, the heroine, Alice the Bloody Black Rabbit, a rough girl who used to be a human until her best friend, a stuffed rabbit named Oz, came to life and was used as a tool of destruction against his will. She killed herself to end his suffering and then her soul took over his body, stealing his power, wiping her memories and her sister's in the process.
    • Gilbert, Oz's little servant who used to be Jack's servant Actually, he was Glen's servant, and he acquired amnesia via being STABBED in the back by Jack. Oz is an Artificial Human whose true form is an Animate Inanimate Object; a stuffed plush rabbit that came to life and wound up in his contractor's body that was deaging and believed himself to be human. He lost all his memories of being B-rabbit somehow-the manga hasn't explained that yet.
    • Also, Elliot lost his memories of killing his own family with Humpty Dumpty's help.
  • Masane Amaha in Witch Blade plays this straight with #3 (classic trauma induced amnesia), but this is subverted later when she never gets her memories back.
  • Strawberry Panic!: Amane falls from her horse and forgets that she was going to enter the Etoile election, and her relationship with Hikari. She remembers having been asked to enter, and the rest of the details of her life. (This is surprisingly similar to the post trauma memory loss that is actually but rarely incurred by some people.)
  • In The Big O, a major part of the original plot is that everyone in Paradigm City — and apparently whatever is left of the world, as well — has amnesia of unknown origin. Unable to recall who they were before the incident (but still retaining most of their day-to-day survival skills), everyone begins life anew. Then odd and disturbing reminders start appearing, many years later... The finale implies that they're all characters in an anime series.
  • A Wind Named Amnesia deals with the whole world suffering from sudden amnesia and not a pretty type: people were turned down to almost animal behaviour while only the main protagonist was restored to humanity by psionics and training.
  • Bleach has a similar memory erasing plot device, with the downside that the blank is generally filled in by something random from the person's imagination. It has fun with what the blanks are filled with, such as a particularly strange character who "remembers" that the reason there is a hole in the classroom and a missing student is because an army of monkeys burst into class and dragged him away.
    • They later gain an upgraded version without that particular problem, but by this time half the cast has some level of spirit power, and thus the memory modification fails to one degree or another on them.
      • The third movie has villains that can perform a different method that erases entire characters from others' memories. It's surprisingly thorough to the point where a character who trained like mad to get strong enough to save an erased character forgets his training and thinks he's much weaker than he actually is. It can't erase physical evidence, however, and Crazy-Prepared Urahara immediately notices discrepancies in his notes and memory and figures something's up. And The Hero's powers are so intrinsically tied to having met the erased character that it doesn't work right on him.
  • Kaito of Mermaid Melody Pichi Pichi Pitch presumably gets a bump on the head that causes him to selectively forget everything about Lucia and mermaids. Of course, this turns out to be an evil plot (and a rather lucky one for Michel at that— he gets the energy from Kaito's memories and blackmail to try and convert Lucia to his side).
  • Happens to a lot of Kanon characters, all for reasons relating to the town's miracles and the tragedy seven years ago.
  • In Ranma ˝, Shampoo uses a technique on Akane to erase all memories of Ranma. She remembers every other person and thing, even when not knowing Ranma means she wouldn't know how she became familiar with them. Apparently, Ranma's father is living with her for no discernible reason.
    • Shampoo's amnesia technique has the added benefit of preventing the victim from ever relearning the suppressed memory, so every time Ranma was re-introduced to Akane she'd forget the latest introduction as soon as he left her line of sight.
    • After accidentally smacking his head with a watermelon in a training accident, Kuno retains the formidable skills he gained through his watermelon training, but forgets his name, his pompous demeanor, and how much money he owes to Nabiki (none, but she's not going to say that). Worst of all, his self-restraint is gone, turning his infatuation with the Pigtailed Girl into a stalker obsession that nearly ends badly for her.
    • One anime episode goes beyond this into Loss of Identity; after falling into the pond and hitting his head, Ranma starts thinking of himself as really being a girl. "She" hates violence, wants to give up martial arts, faints at the sight of blood, freaks out and starts crying after being returned to male form, talks about becoming a bride and goes bra shopping with Akane, has to have Akane help her go to the toilet because "she" can't deal with either set of body parts, rebukes Akane for her tomboy ways and, after Akane finally breaks down and admits that this isn't Ranma and she wants the real Ranma back, "she" tells her that it can't happen. Fortunately, as with Laser-Guided Amnesia, Ranma is restored to normal after Akane knocks "her" back into the pool and makes him hit his head again.
  • Asuna of Mahou Sensei Negima! did this to herself so she could live a normal life. Apparently, she didn't notice not having any memory of her past or the planet she was living on, although her apparent age may have allowed her to Hand Wave the bit about her own past.
    • Happens later on to Yue after the Gateport incident randomly scatters Ala Alba across the Magic World. She has the bad luck to land right in front of a magic student on a broomstick, who not only gives her a knock on the head, but accidentally discharges a memory erasure spell, causing her to lose all of her memories except her name.
    • At the start of the series, Negi attempts this on Asuna when she finds out he's a mage. It does not go as planned. Otherwise, Negima avoids this by having the masquerade instead of removing memories of crazy happenings, just prevent them from noticing all the craziness going on.
  • Lelouch Lamperouge from Code Geass uses his Geass to erase his close friend Shirley's memories of him because she found out that he was Zero and the man responsible for her father’s death and she now reluctantly wanted to kill him.
    • Around the same time, the character Viletta gets shot and falls into the bay, hitting her head and getting amnesia almost immediately after learning Zero's identity. Convenient. She gets better. (Seriously, does it even count as a spoiler at this point?)
    • Suzaku Kururugi had repressed memories from the start of the series after, at the age of 10, he killed his dad the ex-Prime Minister of Japan and doomed his homeland to Britannian rule. He was so traumatized that he blocked his own memories of the issue for years, until C.C. forces it out of him in a confrontation between him and Zero (though in her defense, she didn't have any idea of what she was making him see, only using her powers with the intention to stop him). Mao would do this later again via his Geass and some quick wit, cause a Mind Rape for the poor guy).
    • Later on, C.C. loses her powers and is temporally stricken with amnesia; for her, it's even more severe than the usual case, since she reverts to the state she was in at the last point in her life before receiving a Geass: a ten-year-old slave-girl from the Dark Ages. Though she can still speak...whatever modern language they're speaking.
    • Plus, at the start of season two, The emperor uses a memory-manipulation ability to erase all of Lelouch and his classmates' memories regarding Zero, Lelouch's heritage, and Nunnally. Is there anyone in this show who doesn't have amnesia?
    • Lelouch also does this to himself when Mao holds Nunnally hostage; in order to stop him reading his mind and finding out his plan to save her, he tells Suzaku what to do, then mindwipes himself before heading up to face Mao. It works.
    • Anya suffers from frequent loss of memory, having gaps of time where she has no idea what she did. This is due to Marianne taking control of her body. She tries to compensate by documenting everything she does on a blog for future reference.
  • Tsubasa -RESERVoir CHRoNiCLE- appears to do this to Princess Sakura regarding her relationship with Syaoran; the truth is much, much more complicated.
  • In Hana Yori Dango, Tsukasa is afflicted with bizarrely specific amnesia that causes him to retain all of his memories except those specifically related to the series's heroine, his girlfriend Tsukushi.
  • In Interstella 5555, the main characters, an alien music group, are put in a machine that changes their memories to make them believe they are human.
  • Done very literally in Vampire Knight Kaname uses his vampire powers to wipe out Yuki's memories of Maria being in fact Hio, the vampire responsible for the slaughtering of Zero's family. It does not last long, though, as the effects are almost immediately canceled by Hio herself.
  • In Death Note, owners of the titular object have the choice to give it up at any time, losing all memories of it in the process. However, any repercussions suffered as a result of actually using it (half-lifespan lost for those with the Shinigami Eyes, for instance) remain firmly in place.
    • This is a hilarious example of this trope being played absolutely straight. So Light and Misa, for instance, forget not only the existence of the notebooks and their use of them, but also everything incriminating relating to Kira, while retaining the knowledge that the mass-murderer Kira exists. It not only wipes their knowledge of their own guilt, but that of the other, too, right down to the presence of the secret compartment in Light's watch! It barely only makes sense if you assume that they're reconstructing the holes in their memory in order to make sense of them — "I had no means to kill all those people, therefore I can't be Kira, so obviously none of this can have happened".
    • How to Read states that Light's memories of certain events are altered "so that they make sense". For example, he remembers the fact that he met Naomi Misora, but he doesn't remember most of their conversation, because the lies he told her would only make sense if he were Kira.
  • The Wolkenritter of Magical Girl Lyrical Nanoha A's appeared to have been programmed to forget what really happened whenever the Book of Darkness filled all 666 pages. This gap in their memories greatly disturbed Vita when she realized that she couldn't remember what became of their previous masters.
  • In Nanaka 6/17, the title Nanaka, after being told off by the Childhood Friend she kept nagging and then taking a header down some stairs, loses all memory of everything that happened to her after the age of six. Nanaka's six year old personality simply assumes a wish she'd made to grow up right away actually worked.
  • Watanuki from Xxx HO Li C is a very interesting case. His magically induced amnesia is not only partially anterograde (for example, he can't remember the taste of anything he eats, or even remember if he ate it), but it's also done in such a way that he didn't even notice he had it for quite some time. The discovery gave him a tomato related nervous breakdown.
    • Later in the same series, everyone except close friends and relations forget who Yuuko is when she dies. She'd been living on borrowed time and so the universe rewrites itself to be as if she'd died when she was intended to. Actually, part of the reason why Watanuki's desire to see her again seems to manifest such a severe obsession that he'd adopt her mannerisms and wear her clothes, is because of his fear that one day he'll start to forget her too. If he keeps her belongings close to him, he figures that they'll serve as reminders to prevent that from happening.
  • One of the types of mushi in Mushishi can cause this, erasing all of your personal memories up to that point. This is precisely what happened to Ginko as a child, something that also left him unaware of his other condition...
  • Used regularly in Fruits Basket, whenever someone learns too much about the Sohma family, thanks to the local doctor and family member Hatori Sohma. Tohru is threatened with this, Momiji's mother chose to forget him because she could not cope with the curse, and Kana had to go through it after being put through Mind Rape.
  • Implied in Axis Powers Hetalia with Ludwig aka Germany. If this is the case, he probably lost his childhood memories of being the Holy Roman Empire as time passed and he fought in too many wars.
  • A reoccurring plot point in Fushigi Yuugi, first seen when Yui feeds Tamahome a drug to make him forget who he is and turn evil.
    • Second, as Amiboshi turns out to be Not Quite Dead but doesn't remember his past at all. The amnesia was guided by his new family, who are big fans of this trope and try to "help" Miaka by pointing some amnesia her way, too.
      • Done again to Amiboshi by Suboshi, no less. Amiboshi tells his twin to not fight the Suzaku warriors and take the amnesia-inducing juice/soup. Suboshi does and kisses Amiboshi because Suboshi doesn't want to forget Yui, on whom he has a crush.
    • Third, in the OVA series, Tenkou uses MacGuffin Spheres to systematically erase Taka/Tamahome's memories of his allies.
  • Crops up several times in Mx0, like Taiga's memory of the entrance exam and the Lotus-Eater Machine portion of the exam, in which leaving the 'machine' let you pass but erased your memories (which you kept if you failed).
  • In Red Garden, the four main girls remember little more than brief, vague flashes of the night they died and certain events connected to this. This gets resolved later, but it turns out that Laser-Guided Amnesia is a side effect of revival in general.
  • Double Subversion in Tekkaman Blade: D-Boy turns out to have been lying about having amnesia, and remembers everything. Then later, he starts losing his memory for real.
  • In Excel Saga Excel gets amnesia after Il Palazzo shoots her and leaves her for dead. In this case, it's unclear if she repressed her memories or lost her memories because she was hit by a car.
    • In the manga Excel gets this twice. The first time was brief and played for laughs. The second time it lasts a lot longer, and her personality is flipped. It is also suggested this isn't the first times she has lost her memories.
  • Elie gets this twice in Rave Master. She doesn't know her name or how to control her magic, but she can remember how to read a language no longer used in the modern world.
  • In Kenichi: The Mightiest Disciple, Elder Furinji has a technique called, 'Shockwave of Forgetfulness', a soft punch that can cause the victim to lose his memory. He did it once on a crimelord in Thailand to make him forget he was evil, and again on Kenichi- to make him forget about the really expensive drawing Elder bought, which he was going to tell Miu about.
  • Fairy Tail: Jellal, who doesn't remember any of his past crimes or his own terrible life. The only thing he remembers is the name Erza.
  • Some of the Imported Alien Phlebotinum ("M.E.") in Darker Than Black can do this. It's generally used to make people forget about contact with Contractors or to Unperson them.
  • Pai suffers from a supernatural case in 3×3 Eyes. Pai and her grandparents believe that she's an Ordinary High-School Student who lost all of her memories in a bus accident, but in actuality she's a 300-year-old immortal Sanjiyan Unkara who had her memories sealed by The Dragon so she couldn't interfere with their plans. They even gave her and an old couple false memories and photos to give her a "backstory" and a belief that monsters don't really exist.

    This sealing also has a tragic twist: The Dragon used a minor demon called Houasyou as a basis to "forge" the seal on Pai, who would enforce the seal and keep the Sanjiyan Unkara dormant. But since Pai has a split personality between a Genki Girl and Tsundere, the seal has an unexpected side effect — Houasyou herself lost her memory, and thanks to the Masquerade, she believes that she's Pai. And when the good guys finally confront The Dragon to get her memories back, that means Houasyou has to accept that she's actually a demon and won't be able to be with her love Yakumo because he loves the real Pai, not her.
  • Yu-Gi-Oh! GX: After suffering from nightmares for an unknown period of time because of Yubel being in pain after being shot into space, Juudai was given the most advanced treatments to completely block out his memory of her. This also apparently blocked out his memory of the contest he'd won and the Neo-Spacians that he'd created. He didn't remember Yubel at all, however, until he actually saw her in her own true body again.
  • Yu-Gi-Oh!: In the first series, one of the most important plot points was to recover the memories of the Nameless Pharaoh, aka Yami Yugi. It turns out he himself gave up his memories and bound his soul to the puzzle in order to seal a bigger evil, which had to be defeated near the end of the series.
  • In One Piece, after meeting the cute mermaid Camie/Kaimie/Keymie, Zoro promptly deletes his memory of having met the not so cute mermaid Kokoro through sheer willpower.
    • A more straightforward example occurs later in the Dressrosa Arc with Sugar, who's fruit power not only turns people into toys but erases everyone else's memories of those people. Which makes for some drama when the toys try to get their friends and family to remember them and are seen as defective and taken away, more drama when Robin is turned into a toy, and a Crowning Moment of Awesome when Usopp manages to knock Sugar out and undo her powers causing all the toys to transform back into humans and everyone else to remember them.
    • An even more straightforward example comes in the form of Charlotte Pudding, who ate the Memory-Memory Fruit. This fruit allows the user to pull memories out from someone's head in the form of a strip of film and perform edits on them. The first use seen had our user take a pair of scissors and cut out memories from Reiju that she could've used to inconvenience Pudding later on. Reiju does notice a gap in her memories when she comes to, and Sanji, who had witnessed that point in time in secret, fills Reiju in on what happened.
  • Done to Hisoka in Descendants of Darkness by Muraki in order to erase the memory of the night that Muraki raped him and marked him with a slowly fatal curse. Muraki later removed the memory block when he thought it would be amusing to make him remember it.
  • Milk Crown and its sequels. The protagonist, Oto Tachibana, loses her memory at least three times.
  • Karin: The vampires can hypnotically erase memories of the feeding from the people they bite.
    • In the manga, this happens to Karin herself. Once she's freed of the curse, she no longer has any vampire traits, so her family erases her memory of them in order to allow her to live as a human, who thinks she was orphaned. Apparently, they'd been planning to do so for four years, preparing her mind so that she would only forget about vampires and nothing else.
  • In the second, '80s series of Himitsu no Akko-chan, the title heroine carelessly outs herself as a Magical Girl in front of her whole community of friends. While at first her empowering entity doesn't take it well, stripping Akko of her powers and her reflected image, later settles for a new, stealthier mirror and free Laser-Guided Amnesia for everyone involved.
  • Necrolyzation has this effect on people in Gungrave. It also usually strips the reanimated person of emotions as well. The protagonist undergoes said process and suffers terrible headaches whenever he recovers a fragment of his memory. Conversely, in the videogame he doesn't get the headaches, and never quite gets over his memory loss—with a few crucial exceptions.
  • Masako Natsume from Mawaru-Penguindrum plays this trope to a T by using her laser-guided slingshot to have all Kanba's ex-girlfriends to forget about him at all.
  • In Switch (2002), Kai lost all his memories from before he turned six.
  • In Gunnm, Doc Ido suffered total mental collapse when Desty Novas revealed the dark secret of Tiphares: all of the citizens of Tiphares, such as Novas and Ido, get their brains replaced with chips at the age of nineteen. Unable to live with this revelation, Doc Ido recorded a final farewell to Alita, erased his own memories a feat made relatively easier since he has a chip for a "brain", and started life anew as an ordinary doctor.
  • Washu does this to the OVA Tenchi Muyo! cast in one issue of the manga. Dr. Clay starts attacking the crew via an old assistant robot of Washu's and forces her into a Sadistic Choice - either fight the robot alone and forget the others, or watch as the robot continues attacking everyone she cares for. She chooses the former and erases everyone's memory of her... but only them, which allows Minagi, a clone of Ryoko, to spot Washu taking Ryo-Ohki to the fight site and be able to push the gang into realizing something's wrong. When they confront Washu, she ends up undoing the Amnesia (which pisses Tenchi off that she did so in the first place), but Sasami ends up undoing it on herself while they're gone.
  • Happens to Yumina in one of the bonus episodes of Sound of the Sky, when she and the main cast (except Kureha) get extremely drunk. Their secret distillery is semi-illegal, and Yumina is a priestess, so she conveniently forgets about the whole thing. Somewhat justified since alcohol can have this effect, but it's awfully weird that she doesn't notice having no memories of the previous night, and she doesn't even get a hangover to go with the blackout.
  • In Kamisama Kiss Mikage made Tomoe forget his relationship with Yukiji.
  • Astral in Yu-Gi-Oh! ZEXAL suffers from this. At the beginning of the series he cannot remember anything about his history or purpose, and can only regain his memories by collecting Number Cards with Yuma.
  • Captain Dan in Planet Robo Danguard Ace Ichimonji Dantetsu, the hero's long-lost father turns up with an un-removable mask after 10 years as the villain's mind-controlled slave - the mask has not only removed his memories from before it was put on, but seems (since a convenient memory-viewer establishes that he has no memories prior to the accident that broke the mask's control mechanism...) to have prevented new ones forming - however Dan retains his almost unstoppable willpower, a drive for excellence (and revenge!) AND his ace piloting skills which are practically off the charts... After one too many bumps on the head he gets better.
  • Ramia is struck with this in the third Pretty Sammy OVA, "Super Kiss". She encounters an alien lifeform which absorbs all over evil traits, leaving her to wander the beachside as a kindly young woman as Rumiya and Pixy Misa try to find her - both Tsunami and Sasami have no idea what's going on as Tsunami thinks that Ramia is there... which is a doll in front of her. She quickly remembers everything, though, when she finds Pixy Misa and Pretty Sammy fighting the creature.
  • In the first Pokémon movie, Mewtwo erases everyone's memories of himself, the clones and the island. He tries to do this again to everyone in the sequel, but Meowth stops him—so he just wipes Team Rocket's memories instead.
    • He even did this in Pokémon Live!, though as he hits MechaMew2 with enough of Ash's memories to make him faint, it may have been accidental.
  • In the sequel to Tokyo Ghoul, Haise Sasaki has little memory of the first twenty years of his life. He claims to have little interest in regaining his memories, and insists that he's very happy with the life that CCG has given him. As suspected, at the finale of the original series, the organization captured a critically-wounded Ken Kaneki and erased all record of his existence. It isn't clear how much of his amnesia resulted from psychological trauma, brainwashing, or Arima driving his spear through Kaneki's skull twice.
  • A side effect of the serum that Eren was injected with in Attack on Titan. Levi points out how (in)convenient this is.
  • In the movie sequel to "Sword Art Online" Ordinal scale, most of the original 6,147 Sword Art Online Players have their memories of the game temporary removed after being defeated in the AR game ordinal scale. which is used in creating a AI from a dead player
  • In Dragon Ball, it's revealed that Goku, as a child, fell off a waterfall and bonked his head, erasing any memories he had as the low-class Saiyan warrior Kakarot. This proved to be a good thing as Goku was planned to raze Earth to be sold by Freeza. Instead, he became instrumental to Freeza's defeat. Twice!
  • Overlord (2012): Ainz' first contact with the natives of the new world is with two little girls who are understandably terrified of the giant skeleton who just murdered an armored knight intent on killing them and turned him into an undead abomination. So he edits their memories so they remember he saved them, but not what he looks like (he always wears a mask, a helmet or an illusory face from that point on).

    Comics 
  • In an early Incredible Hulk comic, Betty Ross is kidnapped by baddies and taken to their underground lair. Hulk goes down and rescues her (at the time, the Hulk was intelligent), beats the baddies and proves that he's not evil after all. During the tram back up the mine shaft it's revealed that Betty has forgotten the whole event due to stress. This is while she's still in the same room as the guy who just rescued her.
  • Virtually all of Wolverine's character and most of his plot arcs are based around his adventuring past which he cannot remember — or remembers wrongly. Around the time his origin was finally revealed, it came to light that his Healing Factor works in a psychological capacity as well, and actually scabs over especially hurtful memories.
  • In the 1950s, this was used as the basis for a Heel–Face Turn by Catwoman, in the same story that introduced her now-canonical civilian persona of Selina Kyle.
  • The backstory of the retcon hero The Sentry says that he erased the entire world's memory of his existence. Himself included.
  • The third Flash (Wally West), after years of having his identity public, enlists the aid of the Spectre to erase everyone's memory of his secret identity. People remember both The Flash, and Wally West, but not that they are the same person. They even remember having known his identity, but for some reason can't recall it. In an unexpected side effect, this initially affects Wally himself.
  • In the DC miniseries Identity Crisis, it is revealed that one of the reasons the JLA has been able to keep their identities secret over the years is by having Zatanna strategically erase the knowledge from the minds of any villains who find out. The story was set into motion years before when they attempted to forcibly reform Dr. Light via this method, and it went horribly wrong.
  • Following one of the times his identity was made public, Iron Man used a villain's mind control powers to wipe the memory of everyone on Earth. This is supposedly before the Dork Age of Smug Snake Civil War Tony, although it may have been one of the seeds of this (notably, Captain America was very unhappy).
  • Before Planetary recruited him to become the third man, Elijah Snow lived in a shack in the desert with gaps in his century-spanning memory you could "chuck a nuke through". His work with the field team leads him to prod at these gaps and learn that the mysterious Fourth Man behind Planetary is him, and that The Four forced him to allow the memory blocks after they captured him and his team.
  • Disney Ducks Comic Universe:
    • In Don Rosa's Uncle Scrooge story "Forget It!", Magica uses a wand that causes anyone hit by it to start forgetting things related to words they hear after they hear their name, and uses it on Scrooge and Donald Duck in her latest effort to steal Scrooge's #1 Dime. Hilarity Ensues as Donald and Scrooge forget how to use doors, stairs, and even how to stand up and walk due to Magica's spell. It backfires when she gets away with the dime, but the malfunctioning wand makes her forget why she wanted it in the first place!
    • In Carl Barks' "House of Haunts", Scrooge was also given amnesia by the Beagle Boys by a blow to a specific spot on his head. This gave Scrooge the specific amnesia of forgetting everything that happened since last November. Tapping again apparently is a complete cure.
    • In the Paperinik (Donald's superhero alter ego) stories, Paperinik has candies that wipe memories, normally slipped to people who have somehow found out Paperinik's Secret Identity (notably, the first known victim is the candies' own inventor Gyro, who took them willingly upon being told by Donald. Other stories in which Paperinik has to tell him always end with him wiping out his own memory once again). The candies also reappeared in Paperinik New Adventures, when Angus has stumbled on the secret of the Ducklair Tower and is slipped one after he tells the other journalists the admittedly ridiculous ending of the adventure (that Paperinik and allies had caused to make him not be believed).
    • Also from Paperinik New Adventures, Everett Ducklair has ray guns that cause this effect (and planned to use one on Paperinik to make him forget what he knows of his secrets, but ends up using it on himself to forget Paperinik's secret identity in gratitude for him saving his daughter), and the Time Police is prone to enact memory wipes on people who know too much and are believed can't be trusted with their secret.
    • In Double Duck (set in the same continuity as Paperinik New Adventures) the Agency has the Total Reset Button, a treatment that erases someone's memory of something that is used on former members that quit (they also make them record a video message to prove their identity and that they were paid for their job in case they must recall them in service) or people who know too much. The Agency can reverse it, but it's a difficult procedure that doesn't guarantee full results. Like with Gyro's candies, the memory may sometimes be partially recovered through emotional shock.
  • In Supergirl: Cosmic Adventures in the 8th Grade Belinda flicks a "memory erasure pressure point" on Lena Thorul's head, which makes her forget all about Supergirl's secret identity. Supergirl refuses to believe it worked. The actual amnesia was caused by Streaky the Super-Cat's psychic powers.
  • Mandrake the Magician has had parts of his memory erased several times, usually by well-meaning, but condescending aliens and time-travellers who thinks it's too dangerous to let him remember all the fantastic things he has seen. The poor guy's had a lot of amazing adventures that he will never know about.
  • Not so long ago it happened in Thunderbolts: When they have to kill Songbird, Headsman, Ghost and Paladin betrayed and defeated Scourge and Mr. X, and let her escape. Then Ghost removes this even from Scourge's and X's short-term memory
  • When Maxwell Lord was resurrected in Blackest Night, the first thing he did was to use his Psychic Powers to mindwipe everyone on Earth of all of their memories related to him except for his old Justice League International teammates and the Blue Beetle scarab. He went even further to maintain the illusion by implanting Fake Memories such as Ted Kord committing suicide and Ice trying to murder Guy.
    • Which causes still-unexplained plotholes, as several people implied affected expressly would not be given the storyline. While it's unlikely that, for instance, Kilowog would bring Max up in casual conversation, or that an egomaniac like Manga Khan would give Lord a second thought, Wonder Woman was expressly described as immune to his powers, which is why she was able to kill him in the first place. She's affected like all the rest. However, this is due to the fact, at the time Generation Lost was going on, Wonder Woman was going through a Cosmic Retcon which altered everything about her.
  • One issue of Damage Control had the company hired to repair damage to Xavier's School For Gifted Children from a super-battle. After the repairs were completed and the crew paid, Professor Xavier used his telepathic powers to erase their memories of the school's location and students.
  • Doctor Strange does this on occasion, usually to help people recover their sanity after stumbling into something their minds couldn't handle.
  • In Fleetway's Sonic the Comic, when Super Sonic was split off from Sonic, he completely lost all memory of what he was. He forgot that he was an embodiment of pure malevolent evil. He even lost his super-super-speed and world-destroying powers because he forgot he had them and became just a regular kid for a while. Of course, Super Sonic being normal is exactly as interesting as it sounds, especially since he was portrayed as a borderline loser, and it didn't last.
    • On the other side of the ocean, in Archie Comics' Sonic the Hedgehog, Sonic suffers a bonk on the head and loses all memory of who he is. Dr. Robotnik takes advantage of it and turns him against the Freedom Fighters.
  • In the New 52 version of Stormwatch, the Martian Manhunter wipes the memories of superheroes he's forced to interact with, so they don't know about Stormwatch. When he leaves the team, he wipes all their memories of him. He implies he's done this sort of thing before, which may be considered a Fridge Brilliance Retcon as to why Stormwatch think he's also been a conventional superhero, but the heroes he contacted have never heard of him; he's already wiped their memories of his public career!
  • This was used to explain how Spider-Man was able to rehide his secret identity after Civil War. In One Moment in Time, he convinces Iron Man, Mr. Fantastic and Doctor Strange to help him fix this. A combination of Strange's magic, Reed's nanobots and Tony's Extremis link allow them to erase everyone's memories of Spidey's identity... except for Mary Jane's, which Peter makes sure doesn't happen and Kaine because the spell thinks he is Peter. Peter later broke the spell, unwittingly, during Spider-Island, when he revealed he was one of the many who had spider powers. The knowledge of who he is remains wiped from everyone's memory, but now others can find out.
  • In Red Hood and the Outlaws #19 , Red Hood has S'aru remove every single memory of his that The Joker touched to let him start anew. Unfortunately, this is almost everything he remembers. By the end, he doesn't have the slightest clue who Arsenal or Starfire are.
  • At the end of Tintin Flight 714 Kanrokitoff hypnotically strips everybody of their memories of what happened. Except for Snowy, but he can't tell tales...
  • in Astro City, Beautie can't remember anything from before a time when she was flying over a meadow. If she learns anything about herself before that time, she forgets it too, often within moments. Turns out her creator ordered her to forget it. Sometimes, her distress at her ignorance is strong enough to pre-empt it.
  • In Amulet, Gablian is fond of using memory wiping as a tool, either using the threat of it to get information, or extracting the information anyway if the target refuses, leaving them in an amnesiac state that can take years to recover from. He's also responsible for wiping most of Luger's mind, and Trellis mentions that there are several unexplainable gaps in his memory.
  • In Charles Soule's Daredevil, Matt has somehow forced everybody in the world to forget that he is Daredevil. He only allowed his best friend Foggy to remember.
    • It's revealed that after a fight, the children of the Purple Man decided to "help" Matt by using a machine to broadcast their powers worldwide, telling everyone to forget Matt Murdock was Daredevil and DD was a hero. Matt himself didn't realize it until he went to visit girlfriend Kristen in costume and she was thrown, asking him if he wanted to leave a message with Matt. He went to Foggy to unmask, which caused Foggy to remember but Matt decided it was better Kristen and everyone else didn't.
    • This leads to complications with those DD knows. Elektra no longer remembers so she thinks she was "cheating" on Matt when she was with Daredevil. And Spider-Man notices holes in his memory and forces DD to admit what happened (although not his real name).
    • This actually works out for Matt when Wilson Fisk is elected mayor of New York. When Fisk offers Matt the position of Deputy Mayor, Matt realizes Fisk no longer remembers he's Daredevil and accepts, thinking this is the best way to get in close to Fisk's real plans.
  • Nemesis the Warlock When Nemesis and Purity are waiting in the time wastes, she regains parts of her memory that Nemesis had wiped from her mind. She was recruited by Nemesis to spy on Torquemada after wooing him with a love spell. Though the real reason he made her forget this is because he had also admitted to her that he's far more cruel than he has made himself out to be, having intentionally prolonged the war out of boredom.
    Nemesis: Just because Torquemada is evil, don't assume that must mean that I'm good.
  • In West Coast Avengers, Agatha Harkness removes the Scarlet Witch's memories of her children after it is discovered they don't exist, because the trauma is too much for her to handle.
  • Achille Talon: spoofed at the end of La Traversée du disert. The lieutenant policeman who helped the escaped convicts regrets his betrayal when they attempt to kill all hostages. After Talon punched the wannabe killers, lieutenant tells his sub-lieutenant (who was taken as an hostage) he can now arrest him. Sub-lieutenant smiles and answers the many explosions made him a little amnesic. It's obvious he actually means "I forgive you".
  • Uncanny X-Men: This is one of the powers of the Genoshan Magistrate Wipeout, along with erasing mutant powers.
  • In a Post-Crisis Infinity, Inc. story, Golden Age Wonder Woman's daughter Hippolyta Trevor (Fury) has trouble coping with the fact that not only was her mother and her father General Steve Trevor gone from the mortal realm to be with each other for eternity on Mount Olympus, but that her parents no longer existed in the Post-Crisis DC Universe that emerged. To help Lyta out, her fellow member Brainwave Jr. used his telepathic powers to erase any memory she had of her Pre-Crisis parents, eventually causing her to go on a quest where she discovered that she was the daughter of Helena Kosmatos, who in the Post-Crisis DC Universe was the Golden Age Fury, and that she was adopted and raised by Joan Dale Trevor, the Freedom Fighter known as Miss America, and her husband Admiral Derek Trevor.

    Fairy Tales 

    Fan Works 
  • In Stuck in a World of Fiction the protaganist's memory is almost completely erased in the process of being sent from the real world to the world of Mass Effect . It's later revealed 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 Inverted/Subverted trope
  • Reconnected: West is unable to remember anything before she arrived in Traverse Town at age six, including her real name.
  • In Kyon: Big Damn Hero, Nagato does this to Kyon, Mikuru, and Kanae every night to stop them remembering years and years of training. It's also hinted she does it to stop Kyon remembering kissing her...
  • In Pokémon Mystery Dungeon: Silver Resistance Char, the protagonist, has this to the extent that he doesn't even remember his own name (Char being a nickname given by Saura). Subverted with Saura, who we thought was invoking this trope after being Mind Raped.
  • In the Steven Universe fanfic Long-Term Memories, people who break free of Spinel's mindcontrol forget everything that happened during their posession. Connie forgets one afternoon, Steven forgets two whole days, and Amethyst forgets nearly an entire week.
  • A Star Wars fanfic called Innocence sees Vader suffering brain damage after a crash into Rebel territory. When he learns the facts of his career, he decides he'd rather start as a new man. While he's unsuccessful in getting rid of his breathmask, he adopts some less intimidating prosthetics and swaps his black cape for green coveralls. He rediscovers his engineering talent with Han as a mentor/bodyguard, and after helping the pilots get even with an obnoxious commander, is ultimately accepted as a comrade.
  • Mistakes depicts the nation-tans of Axis Powers Hetalia as unable to disobey a direct order from their human leaders. Thus, 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.
  • In the CLANNAD fanfic An End To All Things, this is the result of some sort of accident, and is the reason why Okazaki doesn't quite remember Kotomi.
  • Friendship Is Optimal The Law Offices Of Artemis Stella And Beat: Vibrant can't remember exactly what happened to her that led to her Brain Uploading into Equestria, beyond that it was "something really bad." Given that she was murdered and the procedure was done to save her, this is probably a good thing.
  • A Shadow of the Titans: After arriving in the Teen Titans world, Jade completely forgets having first ended up in the Pocket Dimension inhabited by the Cackler. Whether this is his doing or incidental is unknown.
  • The Calvin and Hobbes: The Series TV movie "Invasion" has part of Calvin's memory being erased as a side effect of the MTM's Mind Probe. Pretty all of his memories after the original comic strip, undoing all his Character Development. The fear of Socrates' prank manages to restore it.
  • In Let the Heart decide, Saki falls down and hits her head in the hot springs, and as a result, starts thinking Hisa is her older sister instead of Teru.
  • In Origins, a Mass Effect/Star Wars/Borderlands/Halo Massive Multiplayer Crossover, one of the villains is revealed to have had this done. More specifically, after the Eridian Reform faction created Sarah to uphold the Mantle of Responsibility in their stead, she decides they are the ones in need of punishment for breaking the rules they themselves have laid down. After subduing her, they both mind-wipe their "Selfless Servant" and suppress any emotions she might feel. Which makes sense, considering she went into an Unstoppable Rage after she found out what they'd done to try to get out of doing their sacred duty.
  • In Mega Man Reawakened, coming back from the dead leaves Robert with little memory of his human life at first.
  • In The Student Prince, Merlin uses his magic to wipe Arthur's memory of what happened after kissing Arthur to lift a spell and bring him back to his senses.
  • Discussed in one chapter of The Twilight Child, 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 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.
  • The Bridge gives us Monster X. Other than scattered, almost nightmarish still flashes of a kaiju 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.
    • Leads to him joining the Big Bad's forces, after the latter promises to restore his memories.
  • In Friendship Is Magical Girls, Twilight has a spell designed to erase memories, which she uses to maintain The Masquerade. The only time it doesn't work is on Rainbow Dash in their first encounter; while she doesn't remember the details, she knows afterwards that she's met Twilight before, and that there is something she can't remember. This leads to her hounding Twilight until Celestia orders her to undo the spell and explain things. It's implied the whole reason this happened is because Rainbow's status as an Element Bearer protected her on some level.
  • In Deserted Distractions, Yami Bakura can erase memories, and he plans to do so to Tea so Yami Yugi won't come after him.
  • Lupine Tree Has the "Other," a human soul whose memory was damaged in the process of being brought to Equestria. Has type 1 Laser-Guided Amnesia.
  • Invoked in Thousand Shinji when Shinji wonders if he can have this to forget the damned 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?”
  • There are increasingly obvious hints in Universe Falls, 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 Rose Quartz had their memories erased with the help of 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, their reactions hinting it had something to do with Bill Cipher.
  • In Secrets Ron and Hermione ask Harry to Obliviate their knowledge of Horcruxes after Voldemort's defeat so that no other dark wizards can learn of the technique from them.
  • Escape From the Moon: Doa has no problems functioning like a normal pony, but suffers Loss of Identity every time she wakes up from her odd dreams of dying. It stops working after she regains her full memories in chapter 6.
  • In Weight Of The World 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 (erasing memories of what Atlas did to them), and himself.
  • In Anonymooses Monster Girl Saga, Laven wakes up the beginning of the story unable to remember who he is. While he retains his procedural memory, he can't even remember his own name - he takes a new one from a bed of lavender flowers. As the story progresses, he experiences flashes of his original life.
  • In the True Blood fanfic How Could You Forget, Antonia ends up erasing Bill Compton's memories instead of Eric Northman's. Bill remembers that he's a vampire, and that he can play the piano, and not much else. He also has a few memories of his maker Lorena, and Jessica has to help Bill re-learn just enough about the vampire politics in Louisiana so that he can go out in public and not give away his amnesia to other vampires, since he is their King.
  • In Spa Day, Missy cannot recall why she regenerated but she can tell that it was not a pleasant experience.

    Film — Animated 
  • Happens to Barbie, Ken and Raquelle at the end of Barbie: A Fairy Secret. When all is taken care of, Princess Graciella sends the three home, but their memories of the fairies and Gloss Angeles are erased, and they think it was all a dream.
  • When Elsa in Frozen accidentally hits her sister, Anna, in the head with her ice magic, her parents bring them to a troll colony to save her. The oldest troll then alters Anna's memories of Elsa's magic so she won't remember her sister has powers "to be safe". The grown up Anna later learns of Elsa's powers and accepts them, but she never regains her old memories.
  • In Hotel Transylvania, Dracula tries to do this on Johnny and fails due to Johnny's contact lenses blocking the effect.
  • Literal example in Pixar's Jack-Jack Attack, and explicitly shown in a cut scene from The Incredibles. Plays a little like mind rape, since Huph is trying to hold on to the original version of the events.
    • It proves to be not quite laser-guided enough at the start of the sequel when Agent Dicker does the same thing to Tony, after Bob had advised him that Tony had inadvertently seen Violet in costume but out of her mask. Dicker removes Tony's memory of having discovered Violet's identity, but in the process also inadvertently wipes his memory of agreeing to go on a date with her that Friday, resulting in her getting stood up. This causes some conflict between Violet and Bob when she realises what happened.
  • The final resolution of Phineas and Ferb The Movie: Across the 2nd Dimension: all the kids agree to have their memories of the day wiped in order to keep Perry. Isabella used this to give Phineas a Forceful Kiss, knowing she wouldn't remember. Though Perry kept a secret stash of photos on his digital camera.
  • Used in Wreck-It Ralph by King Candy to make everyone forget that Vanellope Von Schweetz is the actual ruler of Sugar Rush instead of a glitch.

    Film — Live-Action 
  • Discussed in The Adjustment Bureau. The adjusters threaten to reset David: "Your emotions, your memories, your entire personality will be expunged."
  • The entire Bourne (Identity, Supremacy, Ultimatum) series of films have a protagonist who has amnesia induced by a psychotic break while on a mission. His amnesia could be organic as well as psychological, since it's implied that he and his fellow assassins are/were taking some sort of medication to supplement their conditioning, and he's obviously not taking it anymore. It could be why he can't recover any of his memories, despite his best efforts.
  • A strange mix of anterograde and retrograde amnesia is played for laughs in Clean Slate, where Dana Carvey's character has forgotten his entire past and forgets the events of each day as soon as he goes to sleep.
  • In Cypher, Applied Phlebotinum is used as a brainwashing tool in order to turn employees of a Mega Corp. into unknowing corporate spies. Whilst they don't completely forget about their formers lives, the corp makes their new "fake" lives such a facsimile of the old one that they never notice.
  • The central premise of Dark City. A man wakes up with no memories of his identity, but has lingering emotional resonance with certain people and places. How much of his personality is truly his remains a mystery — it's implied that his love for his wife is genuine, but at the same time, he's also driven to visit Shell Beach, a place everyone's visited but nobody can describe its location. It doesn't exist, until the end when he makes it exist. He finds his mindwiped wife there, and the movie ends before revealing whether her feelings toward him were genuine or induced.
  • One skillfully executed example is the 2004 film Eternal Sunshine of the Spotless Mind, which concerns a company that can specifically erase your memory of a particular person, used (for example) when a subject wishes to forget a devastating love affair. The explanation of the process is mainly technobabble, but is believable and internally consistent, with some noticeable secondary memory loss.
  • The plot of The Forgotten revolves around the protagonist realizing that no one remembers that her missing son even existed (even her husband), except for her. In the end, she discovers that it's all a part of an alien experiment to test parental connection to their children. She's the outlier, who retains her memories, even when the alien manages to forcibly rip the memories of her son's life from her. Luckily, she still remembers being pregnant, causing the memories to come back. The alien is punished by his superiors for his failure, and her son is brought back, along with the other kids.
  • In Jupiter Ascending, the space police and bounty hunters come standardly equipped with the ability to make people on the worlds they're visiting forget any of the things they see that are out of the ordinary, including inducing laser-guided amnesia and building back structures that were damaged in combat that the visitors were involved in. However, the fact that people that may have been killed during the fight wasn't brought up.
  • Invoked in the Korean Lost and Found. After a car accident reunites her with her high school crush, the protagonist pretends to have amnesia so that he'll have to take of her. Her doctor lampshades it, saying she seems to have gotten "TV amnesia" that wiped her memory but left all her other skills intact.
  • The Neuralizer from Men in Black, also known as the "flashy thing". It can be set for a specific length of time and leaves the victim in a brief trance so a cover story can be planted to maintain Plausible Deniability. Agents are also issued special sunglasses to prevent accidental self-neuralization.
  • The Paycheck film features literally Laser Guided Amnesia (neurons destroyed with lasers), as a method to prevent engineers to trade out top secret technology after finishing their assignment.
    • It also appears to work flawlessly, but can only be used for erasing short periods of time (up to a few weeks). For longer periods, they switch to a chemical agent which is supposed to do the same job. It doesn't work quite as well, leaving behind pieces of memories.
    • In the original Philip K. Dick short story, this is basically what motivates the protagonist to have to seek out the company that hired him and a find a way back in, since the memories are literally burned meaning there's no way to co-operate with the police (who know he's been up to something illegal) and thus avoid prosecution.
  • In the 2009 film Push, there exist people called Wipers, who can temporarily or permanently erase memories, useful as there are other people in that universe who can read minds and memories. Wipers can wipe all memory up to a certain point, or try to wipe only certain memories relating to specific topic, but the accuracy of the wipe is determined by their skill. Pushers can do the opposite and convince someone that a specific event really happened, when it really didn't (then again, this is just a more effective means of something humans can already do perfectly well, since memory is a very pliable thing). They can also convince someone that something didn't happen, making them think that the real memory was imagined.
  • Happens to Alice and Spence Parks in the first Resident Evil movie as a side effect of being rendered unconscious by sleep gas.
  • In Superman II, among many other superpowers that pop up out of nowhere, Superman is revealed to have the ability to remove specific memories with a kiss. This becomes a bit more disturbing in Superman IV: The Quest for Peace, where he comes pretty close to using this power as a date rape drug.
  • In White Tiger, "Naydenov" cannot remember his true name, his military unit, his date of birth or where he went to school. He can remember how to drive a tank, though.
  • In The Wolfman (2010), it's not so much that he forgot, but rather Lawrence's memories were rewritten so that real memories of his werewolf father killing his mother were made to appear that she had killed herself with a razor.
  • X-Men Film Series
    • X-Men Origins: Wolverine features quite possibly one of the most painful instances of this trope. An antagonist loads a gun with Adamantium bullets, knowing he can't kill Wolverine with them, but intends to give him Laser Guided Amnesia by shooting him in the head. He succeeds, wiping Wolverine's memory with no other side-effects. Wolverine's "memories don't grow back", but his ability to speak, read, walk, recognize police cars, hide from police cars, etc, do.
    • In X-Men: First Class, Charles uses a kiss goodbye to wipe out Moira's memories the last few weeks, and of where he and the newly formed X-Men are. This is notably against his current philosophy in the comics, but very much in keeping with his modus operandi in the comics produced in the early 1960s.

    Manhua 
  • In Infinity Game the previous DM erased all of Trishia's memories (which he created in the first place) and made her Dwarven Defender 00 (D.D.) so she could serve the next Game Master. When Long Wei, the new Game Master, keeps up his DM title so he can enter the game he created, he makes D.D. control the game and forget who the Game Master is so the game is fair.
    • At the end Long Wei does this to the rest of the team. As the RPG Society are trying to take over the alternative world with their previous game (so the players who were erased could come back - of course, doing this erases the current players, even if they're already dead) they froze the flow of time and the war between the them and Long Wei was slow, if he waited until after the war to bring them back to life and send them to the real world it'd be fifty years in the future. He hopes doing this will mean they aren't traumatised by all the events, but they're all vaguely aware something isn't right.

    Music 
  • In the third chapter of mind.in.a.box's story, Black is rescued by the Sleepwalkers when his supervisor tries to erase Black's identity after he learned too much about his supervisor's operations. However, they were either too late or blanked out part of his memory, as he later can't even recall them ("Sleepwalkers?... never heard... what are they?") them and has trouble remembering his name later on.

    Podcasts 
  • Tellie from Sequinox forgot most of the information it needed to tell the Sequinox girls because Caiden ran over it when it first appeared to him. It slowly regains memories, usually right after they could have been useful.
  • The Adventure Zone: Balance: The voidfish has the power to erase people's memories of everything it eats to Cosmic Retcon levels. These memories can be restored by drinking its fluids, by dying, or when the voidfish beams the memories across the planar system.

  • Our Miss Brooks: "Mr. Conklin is Honored" begins with Mrs. Davis relating her sister Angela's recent brush with laser-guided amnesia. Later, Mr. Conklin fakes a case of his own.

    Tabletop Games 
  • Both Vampire: The Masquerade and Vampire: The Requiem have a power called The Forgetful Mind as part of the Dominate Discipline. It allows the vampire to go in and literally rewrite a person's memories by telling them what "really" happened. It's usually used to protect the Masquerade; however, it's made clear that it only really works on more recent memories, and if the account isn't completely comprehensive, cognitive dissonance will ensue.
  • Mages in Shadowrun can learn a spell called Alter Memory, which allows them to do exactly that: alter a single memory, including suppressing it entirely, although the subject can recover it either through willpower or magical help. The government of Tír Tairngire cultivates a fruit called laésal, which can be processed into laés, a drug that can erase up to twelve hours of memory upon consumption and that erasure is complete; it actually "formats" the physical storage of short-term memory in the brain. Leäl is a street drug derivative commonly used as a date-rape drug that removes up to two hours of memory. Cutting cocaine with leäl creates "pixie dust." Snorting it grants increased Charisma, Perception, and High Pain Tolerance, but also shreds your nasal cavities; fortunately, it removes the last few minutes of memory so you won't recall the agony.
  • Dungeons & Dragons has the "Forget" spell as its most basic, and a whole slew of other memory-erasing or memory-rewriting spells from non-core books, like "Forget Past" (Oriental Adventure), "Otto's Tones of Forgetfulness", "Rary's Memory Alteration" (Greyhawk Adventures), "Modify Memory", "Memory Wrack" (Tome of Magic), "Brainkill" (The Complete Book of Necromancers), the psionic science "Mindwipe" (The Complete Psionics Handbook), etc.
    • Holy slayers (assassins) in Al-Qadim sometimes use a "Blade of Forgetfulness": everyone seeing it swung in a certain pattern suffers a complete memory lapse regarding everything that just happened and is about to happen (up to 3 rounds before and after). Not too hard to guess what sort of events tend to be forgotten this way, is it? Those attacked with such swords are very likely to shake off this effect, but usually this doesn't matter anymore.
    • The Dark Powers of Ravenloft do this to beings in the Demiplane of Dread quite regularly, mostly to preserve certain conditions. For example, anyone who takes up residence in the domain of Darkon will forget having ever lived anywhere else within a few months of doing so, and will believe that they and their ancestors have always been from there.
    • The Shadow that transports people, things and beings too monstrous to fall under the people category from undefined fantasy worlds to Earth in the Urban Arcana setting for d20 Modern as a side-effect also strips their memories of any details of those worlds - in effect, they know who they are, but not where they come from beyond Standard Fantasy Setting.
  • In GURPS Black Ops, the agents of "The Company" have a drug they can slip to someone who has Seen Too Much. They get what seems to be a nasty one-week case of flu, and forget what happened right before getting drugged. The Infinity Patrol from GURPS Time Travel have Eraser, which fits this trope even better — the drugged person blacks out for a bit, and wakes up without memory of the time immediately preceding the drugging. In Black Ops the existence of aliens and monsters must be kept secret, and the Infinity Patrol cannot let anyone know that parallel universes exist.
  • In Magic: The Gathering, Jace, the Mind Sculptor's ultimate ability wipes its targets' minds clean of all their spells, deleting their decks and blocking access to their hands.
  • The new M-X-Saber Invoker who suddenly joined the X-Sabers in the Yu-Gi-Oh! TCG? He's actually Souza, but he lost most of his memories.

    Theater 
  • In Richard Wagner's Götterdämmerung, Siegfried is drugged to forget that he ever met Brunnhilde, but remembers killing the dragon Fafner and all his other early deeds (closely following the plot first found in Völsunga saga). Later, Siegfried steals the Ring from Brunnhilde, but promptly forgets this.
  • Fuddy Meers: The condition that Claire has, wiping her memory clean every day. Interestingly enough, she can recall distant memories easily with a little help.

    Video Games 
  • A justified version comes from Another Code, where the Trace has this as one of its functions as a memory control machine. The intent was for it to be used to help remove particularly traumatic memories from people like soldiers or victims.
  • A perhaps more realistic version appears in Super Robot Wars Advance. One of the protagonists starts off with almost complete amnesia — he can remember instinctive stuff drilled into him, but he can't remember what it's for. His personality is also completely different from his normal personality, and he's noted as "strange" by a lot of the other characters.
    • In Super Robot Wars Z3: Jigoku-hen, the characters from series not in the game have been forgotten about for reasons not entirely made clear. Every time someone tries to think of them (usually going "Wait...wasn't there other people we used to travel with") they immediately get a headache and then forget what triggered that thought. This includes the original Aquarion characters, and even extends to characters in the game. When Kei from Orguss first shows up having come from a dimensional rift nobody can remember him, but after a headache they suddenly can, while Kei himself initially remember the original Aquarion people, but after another headache suddenly can't remember who he was thinking about. Interestingly this includes all previous original protagonists, but not the villains so Aim Liard is the only Sphere holder they can remember, causing everyone to associate Sphere's with villains.
  • In the Street Fighter series, Cammy's amnesia erases all memory of her being a doll of Bison, but doesn't erase her fighting skills. This, despite the fact that she wasn't born, but created simply to be a vessel of Bison's soul.
    • A similar, more recent Street Fighter example of an amnesiac is the French soldier Abel. Much like Cammy in the previous example, Abel is actually a cloned Shadaloo soldier and potential candidate for an alternate body container for Bison. Also parallel to Cammy, Abel is rescued from Shadaloo by a mercenary team.
  • Planescape: Torment both honors and averts this. At first, the nameless main character can't remember his skills, his identity, or anything about the world he lives in, except the language — a seeming aversion. But as the game progresses, it becomes clear that he isn't learning new skills and abilities, but remembering them; he frightens a hedge witch arguably frightens, since the "hedge witch" is Ravel in a different form by mastering years' worth of magic training in seconds.
  • People who have recently died in Ghost Trick lose their memories, and recover them again with varying degrees of speed and depth. Sissel forgets not only his identity, but the meaning of many basic concepts such as "prison cells" and "science", as well as how to read. Except he hasn't. Sissel can't remember them because he's even forgotten what he originally looked like... a cat, who never understood those concepts in the first place.
  • In Kingdom Hearts: Chain of Memories, Sora gradually loses some memories and has others rearranged. Recovering them leaves him in a coma for a year, causing him to forget everything that happened while his memories were scrambled. And for some reason, when Sora doesn't have his memories, everyone who knew him doesn't remember him, either! This is clarified in Kingdom Hearts II, where Kairi is barely able to remember that there was a second boy she hung out with. Selphie cannot even recall that there was ever somebody Kairi hung out with other than Riku.
  • Messed around with in the beginning of Kingdom Hearts II. When Sora, Donald, and Goofy forget their fighting skills, they have to relearn them all. Convenient, since the player's also learning a new fighting system. However, Sora's basic combo in Kingdom Hearts II is more precise and polished than in the original game, and according to Word of God reflects his growing skills as a swordsman, while Donald's magic is visually distinct from Sora's in Kingdom Hearts II, when they shared the same spells in Kingdom Hearts. On the other hand, Roxas in the prologue had his memory wiped by Namine so he would have a normal life before he had to reunite with Sora.
  • It was used in Kingdom Hearts: 358/2 Days for Roxas. After growing close to another member of the organization, a girl named Xion, he discovers that Xion is actually an artificial replica of him that's been slowly eating away his life energy just by existing. The only way to stop it all is for one of them to die. Xion ends up committing suicide by best friend and gets erased from everyone's memory. In the end, Roxas is left with nothing but rage and a great sense of loss, without fully understanding why he's feeling these things.
  • Gig from Soul Nomad & the World Eaters has Laser-Guided Amnesia about everything before being Gig (which doesn't really bother him all that terribly, truth be told). He turns out to have once been the legitimate Master of Death of Haephnes, Vigilance. He was slain by Median and his soul was converted into his current form by Drazil, the Dimension Lord of a neighboring world, before being set loose on the world he was once responsible for.
  • A minor example occurs in Mass Effect 2, where if you saved the rachni queen in the first game, you meet an asari on Illium. She says that the queen saved her life, but she can't remember where the rescue occurred because the queen removed the information from her mind: "It's not painful, but I simply don't remember."
  • Almost all of the townspeople from Final Fantasy Fables: Chocobo's Dungeon is afflicted with this, due to the influence of the Bell of Oblivion. Trying to remember even the simplest things becomes painful for them, and it's up to Chocobo to dive into their memories and recover the missing pieces.
  • In Final Fantasy VII, Cloud Strife has a rather severe case of amnesia, due to multiple traumatic events, that led to him wiping his friend Zack from his mind and replacing Zack with himself. Therefore, Cloud, who had been just a common grunt in Shinra's army who failed to make it into SOLDIER, believes he was a SOLDIER First Class and now is a mercenary in Midgar — something Zack told him he wanted to do. He also can't remember anything that happened after he (Zack) faced Sephiroth in one of Shinra's Mako Reactors.
  • In Final Fantasy VI, Terra begins the game with almost no memories of her past. Some reemerge quickly, while others do so only slowly. And traumatically.
  • In Final Fantasy VIII the main characters almost all have amnesia which has been caused by the use of guardian forces. With the exception of Irvine who had never used them, all of them had forgotten that they grew up together in an orphanage. Fate still causes them to find each other and work together.
  • In Final Fantasy IV, Yang washes up in the Kingdom of Baron having lost his memory and so becomes a member of the local guards. He fights the party when encountered and has his memory restored by being beaten, after which he rejoins the party.
  • Subverted in Final Fantasy X as Tidus does have a full recollection of all of his memories but keeps having to pretend to have amnesia caused by Sin's toxins as he has no knowledge about the world of Spira and his being from Zanarkand seems completely impossible to the residents. His skill as a blitzball player is what makes him go along with the party and find out what is going on. One could wonder why he never does develop actual amnesia though as he is exposed to Sin quite often during the game.
  • The main character of Vagrant Story, Ashley Riot, is a classic example in that while he's an amnesiac about events, he's still the perfect agent. He does start with only basic battle skills, though, and remembers them gradually over the course of the game. It does take a Dark-filled city of the dead to do it, though.
  • King Varian Wrynn, the hero of World of Warcraft: the Comic, was kidnapped, cursed to forget his identity and dumped in a hostile shore, so Onyxia, the villain, could rule his kingdom through his doppelgänger.
  • In Lost Odyssey, Gongora gives Jansen a device to use in case Kaim or Seth recover their memories. Not the first time Gongora ever used them, and Jansen throws it at a guard instead.
  • Knights of the Old Republic has an important plotline revolving around amnesia. The amnesia is the player-created protagonist's, who is in fact a specific backstory character and not the generic grunt he/she seemed to be. Yes, there are some false memories involved.
    • It should also be mentioned that this is meta in a quite ridiculous degree, given that KotOR is a role-playing game. It manages to neatly explain how your apparently adult and very capable soldier/rogue/mage doesn't know how to put on clothes or open doors. While it's just teaching you how to work the game mechanics, it has an in story explanation that your memories have been messed with perhaps a little too well.
  • Happens three times (at least if you're after the good ending) in Cave Story. To injured robots. The third time, Curly actually forgets everything that happened since the last time she woke up with amnesia.
  • In the new thirteenth ending of Chrono Trigger DS, Anti-Hero Magus attempts to rescue his sister, who has fused with a monstrous entity, and fails. She sends him back to 1000 A.D. with no memory of who he was or where he came from. If this memory loss is meant to be a deliberate act of mercy, it fits this trope; if accidental, it's Easy Amnesia. Either way, it's strongly implied that the amnesiac Magus is Guile of Chrono Cross.
  • In Xenogears, the Limiter causes an entire planet to forget whatever The Chessmaster Krelian wants them to forget, from history to the existence of entire continents. Naturally, the heroes move to undo this.
    • The protagonist himself has amnesia thanks to multiple personalities having memories of most of his life before he turned fifteen.
  • A lot of adventure games exhibit this, simply by not giving the player much information about the setting they're exploring.
  • The ending of Sly 3: Honor Among Thieves has Sly forgetting his identity after the final boss fight to his rival Inspector Carmelita Fox, with her telling him that he's actually her Interpol partner and the two escape the island. He later leaves clues for his teammates that he's faking this so that he can pursue a romantic relationship with Carmelita.
  • Guillo from Baten Kaitos Origins remembers absolutely nothing from before meeting Sagi. And everyone, especially Guillo, were much better off that way.
  • Lampshaded in Wild Arms XF. Early in the game, Labrynthia believes that Clarissa must be Princess Alexia due to their striking resemblance. When Clarissa denies it, Labrynthia hypothesizes that she must have lost her memory in the accident that was supposed to have killed Alexia. Clarissa responds with this gem: "What? That only happens in stories! Real people don't lose their memories that easily!" Later on, it turns out that both Clarissa and Alexia were in an accident at age three, which lead to both of them losing all their memories and being mistaken for each other. So Clarissa really is Alexia with amnesia, just not the Alexia that Labrynthia knew.
  • Neku in The World Ends with You starts out not remembering anything before him waking up on the Scramble Crossing. It later turns out that Neku's memories were his entry fee, but even then he still has some missing. This is later explained when Joshua, the resident Magnificent Bastard reveals that he'd 'held on' to some of Neku's memories — namely the missing ones, which showed Joshua killing Neku.
  • In the RPG Hype The Time Quest, the Titular character is turned into stone and sent 200 years in the past. And when he wakes up, he doesn't even know what button to push to draw his sword!
  • In the end of Mega Man Battle Network 5, Lord Wily does it to his son Dr. Regal. If it weren't for the fact that the former is the series Big Bad, it was just a Shoot the Dog scenario, and an amnesiac Regal loses all of his grudge against humanity.
  • In the bad ending of Mega Man X5, this was inflicted on the title character by Dr. Light so the former will not have any memories of Maverick Zero. Furthermore, any information regarding Zero will be rejected by the same programming that erased X's memory in the first place.
  • Played painfully straight in the campaign mode of Tekken 6, where protagonist Lars Alexandersson has his memory wiped by an explosion in the lab where he found Alisa and it only returns after he squares off against Heihachi Mishima, his father.
  • Phantasy Star: Any CAST that comes back online after the Great Blank exhibits near-total amnesia. Bodies of CASTs that were terminated beforehand are unaffected, as Ogi demonstrates by taking over two separate bodies. As he explains, the head stores the majority of the actual memory and the entire personality of the CAST while the body holds sub-memory the CAST uses. The amnesia is literally laser-guided, as Mother Trinity employed Photon Noise in an attempt to kill the CASTs that fought against her. The memory damage forced the CASTs offline to prevent total system failure. Those on the moon were purged to a "man", since Mother could not use Photon Noise there without damaging herself. That's not to say she wasn't compromised already...
  • In NetHack, reading a scroll of amnesia or being successfully attacked by a mind flayer will wipe random parts of the character's memory including any levels which have been mapped. Also the names of items in the inventory will revert to their unknown name state.
  • Averted in Mega Man Zero, where Zero's so-called "hibernation sickness" affects motor skills and speech as well as his memory of his past life. In addition, some characters suspect that he may also suffer from anterograde amnesia. note 
  • Alex Mercer of [PROTOTYPE] wakes up on an autopsy table after having apparently been shot to death. He has no memory of his own identity or why a black ops organization is trying to kill him. Much of the game revolves around his slowly uncovering the truth, revealing that the reason he doesn't have any memories is because he's not Alex Mercer. He's The Virus with a physical body created from Mercer's corpse.
  • Weiss in Agarest Senki 2 starts off with him killing a servant of a god and a god. He then gets flung out in the middle of nowhere and gets amnesia as a result. He also gets his level reduced from level 99 all the way back down to level 1. And then in a similar fashion as [PROTOTYPE], Weiss isn't really "Weiss" but instead Chaos aka the god Weiss supposedly killed in the opening! And the real Weiss himself who was the level 99 Weiss actually didn't kill Chaos, but instead got himself killed!
  • The Conduit: in the tie-in comic book "Orange Lights", The Men in Black use specially-designed orange lights to erase Gordon Well's knowledge of the truth behind the Drudge invasion before he can share it to his listeners.
  • In Disgaea: Hour of Darkness, Maderas targeted and stole all of Etna's memories related to King Krichevskoy and her promise to him to blackmail her into working for him, while leaving enough information to know they're important to make sure she complies.
    • Disgaea 2: Cursed Memories combines this trope with Sealed Evil in a Can. Rozalin is the reincarnation of Overlord Zenon. She can remember this only when the seal holding these memories back is broken.
      • Zenon's curse also causes this to every resident of Veldime. They become demons, and start to forget the lives they had before transforming. A couple of the minor characters around town mention the potential Fridge Horror involved; perhaps it would be better to remain demons than to regain their conscience and have to remember what they did while they were monsters.
  • In Dissidia: Final Fantasy it was heavily implied that the Warriors of both Cosmos and Chaos were under the effect of this trope. This was confirmed in the sequel, and given more explanation: the war between the gods is part of a "Groundhog Day" Loop that has been going on for several cycles. When a Warrior is summoned into the world, they are stripped of their memories as result of Shinryu's Purification ritual. As the characters fight on, however, they gradually start to regain more memories about their homelands, though the rate varies form person to person. Should a character fall in battle, they undergo the same purification ritual, reviving them for the next cycle but once again robbing them of their memories.
  • Averted in Tales of the Abyss: Whatever turned main character Luke fon Fabre into an Amnesiac Hero, after he was kidnapped at the age of ten, wiped him clean: He had to re-learn things such as walking and talking from scratch. The first Plot Twist, which is that he is a clone, also justifies it: since he was decanted during the kidnapping, of course he would not have memories or knowledge. The original he, who is still around, is perfectly functional, except for a serious case of Cloning Blues.
  • In Tears to Tiara 2, Hamil doesn't remember anything prior to seven years ago. The first thing he remembers is his father Hasdrubal being burnt alive in front of him and Izebel laughing like mad behind him. His memories were erased and stored in the Sword of Melqart to ensure that the secrets of the Barcids family does not fall into the hands of The Empire.
  • The protagonist of Legend Of Kalevala doesn't remember anything important except that his wolf-like body is an odd piece of work. The main thing he has forgotten is that it's not his body; he's the Brain Uploading replica of a human scientist.
  • Fire Emblem:
    • In Fire Emblem: Radiant Dawn, on the second playthrough, Ike regains a piece of his memory Sephiran erased from him to protect him and Mist. As a child, he witnessed his father Greil/Gawain kill his mother Elena when unde the effect of the Fire Emblem itself, and went temporarily insane.
    • Fire Emblem Awakening:
      • The Avatar is afflicted by this and s/he ends up taken in by Chrom and his Badass Crew, the Shepherds. With good reason: it turns out s/he is the Apocalypse Maiden of the game, whose future self (who was possessed by Grima, the fell dragon) was the cause of the amnesia in the first place when he/she tried to merge with The Avatar.
      • Similarly, at some point the Shepherds can recruit a character named Morgan who also suffers of this. He or she can only remember one person: his mother/her father... the aforementioned Avatar.
  • Flashback starts with the protagonist escaping from a base being chased by soldiers. He ends up crash-landing on Titan. He has no memories before that. He also has a holo-cube containing a message of him telling himself to find a friend of his in an underground city. After finding the friend, he plugs you into a machine that restores your memories (at least, up to the moment when they were recorded). They reveal that your character has discovered Aliens Among Us and has developed a device that can detect them. As a precaution, he had his memories recorded and gave the recording to a friend. The aliens kidnapped him, wiped his memory, and planned to kill him. The protagonist has managed to escape, starting the events of the game.
  • Rodi from the game Shining the Holy Ark suffers this after a cave-in knocks him on the head. It's used to explain away the fact he's forgotten all his skills he displayed in the fight where the player must attack him. Eventually his memories and skills come back as you play through the game.
  • In Pokémon Mystery Dungeon: Rescue Team, prior to the main storyline, the main character loses all of his/her memories from when he/she was a human. Subverted somewhat in that this was by the player's own decision when he/she took on the task of saving the Pokemon world.
  • I Miss the Sunrise has Ros, who can remember everything except what happened before s/he was put in stasis.
    • Anyone can have this, actually, and it is a necessary side effect of immortality; Typelog has devised a system allowing people to replace unused memories with ones they currently need.
  • Played with in Snatcher, where Gillian Seed and his wife, Jamie, remember nothing about who they are or where they come from, though they somehow find out their names and the fact that they are married.
  • In Tokyo Xanadu, Asuka Hiiragi, one of the main characters, is able to use a spell called "Erase" from her phone that can wipe the memories of anyone who gets pulled into the Eclipse. Subverted with the main party who are Wielders, people who are able to fight the Greed, even if they haven't awakened to their soul device.
  • In Fallout 3, Dr. Zimmer's escaped android A-321 has undergone a memory wipe via circuit neuralizer, along with Magic Plastic Surgery courtesy of Dr. Pinkerton and renaming himself Harkness.
  • In Ib, the dolls inflict this on Garry if he fails their little game, causing him to forget what he learned about Mary. It doesn't last though; Mary attempting to knife him jogs his memory.
    • Also, this seems to happen to any human who escapes the gallery. In any endings where Ib and/or Garry escape, they lose all memories of their journey. It's only in the Golden Ending, "Promise of Reunion," that they remember anything, since Ib gave Garry her handkerchief previously and seeing it triggers their memories.
  • In Disney Princess Enchanted Journey, your character can't remember anything other than her name and appearance.
  • Played for laughs (along with everything else) in Escape from Monkey Island, when you need to retrieve exposition from Monkey Island's resident hermit, Herman Toothrot. Basically, whenever hit in the head, Herman forgets everything prior to the specific concussion; moreover, in order to restore his memory, he need only be bonked again, but it has to be with the same item that hit him originally. Thus engages a sequence in which you have to learn the earliest object that he remembers waking up next to, find that object, and chuck it at his head. Of course, you can cause new bouts of amnesia by throwing the wrong thing. Eventually you find what clocked him when he was originally shipwrecked on the island and learn his whole backstory.
  • In Yu-Gi-Oh! BAM, youu can't remember anything about yourself or your past, but you are highly skilled at BAM.
  • In Remember Me, the Sensen brain implant technology allows for memories to be shared, altered, or deleted. In one of Nilin's memory remixes, she finds out that her father is responsible for creating the technology, using it to remove the memory of the car crash she and her mother were in so that she would never remember her mother blaming her for it.
  • Averted in Phantom Dust. Characters affected by memory-destroying dust don't remember their names or anything about themselves, but data logs reveal they also often forget more common knowledge, such as the fact that plants need sunlight to grow.
  • Fallen London has Lethean Tea-Leaves, which will reset your character's Ambition and let you pursue a different one. Normally you buy these with Fate, but if you pursue the "Light Fingers" Ambition, one of your major antagonists will give you a serving as your Last Chance to Quit, with the caveat that if you don't and he catches you fooling around in his business, you'll be Buried Alive. (He can't just kill you because you'd just get better.) If you don't take this offer, the leaves find another use when a kidnap victim has been brainwashed into loving her prison...
  • Team Fortress 2: "The Naked And The Dead" reveals that the Medic is easily capable of replacing the Demoman's missing eyeball, and has in fact done so on several occasions. The problem is that Demoman's eye socket is haunted, causing the eye grows batwings and attacks the rest of the team every Halloween.
    Demoman: Wait, why don't I remember any of this?
    Medic: Oh, that. I scooped that part of your brain out so you'd stop asking me.
    -beat-
    Demoman:
    ' Aye, fair enough.

    Visual Novels 
  • In Rewrite this is one of Shizuru's powers.
    • In addition Kotarou starts the main story with this.
  • In Duel Savior Destiny for the resolution of Mia Touma's route, she has her memories wiped at the end so that she doesn't have to bear the weight of events that occurred in her story line.
  • A justified version comes from Another Code, where the Trace device has this as one of its functions as a memory control machine. The intent was for it to be used to help remove particularly traumatic memories from people like soldiers or victims.
  • In Fate/stay night, Heavens Feel route, Shirou gets a form of anterograde amnesia when he loosens the binding on Archer's arm. It becomes more typical retrograde amnesia later on.

  • Shiki in Tsukihime had his previous memories of his life among the Nanaya clan magically erased by Makihasa after his incident with SHIKI. In fact, he doesn't even remember they existed for the most part and initially thinks of himself as SHIKI, the real son of Makihasa Tohno. Later, Akiha informs him that his memories cannot be replaced and that all records of his previous life were destroyed years ago. But he doesn't really care.
  • In the visual novel True Remembrance, destroying memories is used as a method of treating depression.
  • In Eien no Aselia before the story started Yuuto made a Deal with the Devil to save his little sister. The game starts when the devil in question (a sentient weapon) forces him to complete the contract and at the same time restores his memory of having made the deal. Later, Tokimi wipes his memory again when said sword is destroyed and he is rendered unable to fight.
  • In To the Moon it is revealed that Johnny's mom made him take beta blockers in his childhood in order to make him forget everything before that, including his dead twin brother Joey, it is heavily implied that the reason for this was to mold Johnny as Joey's Replacement Goldfish in his mom's mind.
  • In Dangan Ronpa, 14 of the 15 students of Hope's Peak Academy lost their memories of the two years they spent together. This also erased their memories of "The Biggest, Most Awful, Most Tragic Event in Human History" or "The Tragedy" for short. The only student who did not lose her memory was the mastermind behind The Tragedy and her twin sister, the secret 16th student. However, even though Toko lost her memories, her Split Personality Genocider Syo/Genocide Jack did not.

    Web Comics 
  • Averted in Miamaska: Amity suffers a concussion and has memory problems of what happened for the next six days. She still has fuzzy memories of what occurred beforehand, though.
  • Funny Farm: Mavis forgets two years of her life thanks to a time bomb subconsciously implanted by a cult hypnotist. Later, Boe gets short-term amnesia from an explosion, causing him to forget what happened just prior, including his realization of his love for Mileena. Eventually, he remembers that there was some sort of love confession, though the details are fuzzy. The trope's subverted when it's revealed that the apparent amnesiac is not Boe at all, but Orwell pretending to be Boe and using amnesia as an excuse to not remember specifics.
  • After Wanda finishes interrogating Jillian in Erfworld, the guard comments on the "fascinating" things he overheard and tries to ask a few questions. Wanda tosses some magic powder in his face and tells him, "You heard only the screams for mercy."
  • In The Spider Cliff Mysteries, characters forget that a single day occurred. This was self-inflicted.
  • The Oracle of The Order of the Stick has a charm on his valley that prevents supplicants from remembering anything of their experience there, other than the answer they received for their questions. Among other things this keeps it unknown that the Oracle is a mere kobold, who is less than helpful to his customers. Roy (in ghost form) is able to bypass this when he is banished from the valley back to the afterlife.
    • Also, after his resurrection, Roy cannot remember well any of the time he spent in Lawful Good Heaven (though he remembers the pre-Heaven limbo).
    • Roy exploits this when being judged for entry into the Lawful Good Heaven and his treatment of the Oracle is brought up as a mark against him.
    Bureaucratic Deva: Dangling an oracle out of a window?
    Roy: Really? I don't remember that one.
  • In Freefall, Ecosystems Unlimited developed a number of devices to induce retrograde and anterograde amnesia in Bowman's Wolves, Justified as they created the species and specifically designed them to respond to the devices. A remote emits a sound that knocks the subject out and erases the last few minutes of her memory, while a drug paralyzes the hippocampus for several hours preventing the formation of long-term memory. Hilarity Ensues when Florence is given the drug and ends up wandering the E.U. facility with no idea what she's doing, trying to keep track of thoughts with sticky notes.
  • In Errant Story, when the elf Sarine has some emotional memories of her human husband and half-elf child come up one night, her human traveling companion Jon confronts her. Impulsively, she jumps him. The next day, when he awkwardly tries to bring it up, she casts a memory charm on him, leaving him deeply distrustful of her. He can tell that his memories were manipulated somehow, and whatever was removed, he assumes, must have been far worse than a one-night stand.
  • Earthsong features this trope on any character arriving there, due to the transport process. They still have a "remnant," a memory of the last thing they did before being transported to Earthsong. The two known exceptions to this pattern are Nanashi, who remembers everything of her past life after having wielded the Sideran weapons, and Willow, who doesn't even have a remnant. Considering that Willow is Earthsong's Eve, she probably never had a memory to lose yet.
  • Jigsaw in Last Res0rt has a relatively realistic bout of amnesia surrounding how she became a vampire. To complicate matters, she then apparently proceeds to feed in her sleep, allowing her to go for almost three months before Daisy actually has the presence of mind to just TELL HER she's a vampire.
  • In Sluggy Freelance, the Harry Potter-style wizards have the Forgetyoubliviate spell for this. It's used to erase Torg's memories of Hoggelrynth, and one inadvertently erases everyone's memories of Millard Stoop.
  • In Fleep, the amnesia is so laser-guided that the affected character doesn't even realize he has amnesia (at first). He walks into a phone booth in San Francisco; several years later, he wakes up inside a phone booth on a completely different continent—and with no memory of the intervening events, he thinks he's still in that booth in California.
  • Mixed Myth actually came up with two clever explanations for why the Sphinx Tamit can't remember anything besides her name. Her first explanation is that, since she's immortal, she has to periodically remove her memories with magic to prevent being overwhelmed. It's eventually revealed that this isn't true, and that she's the Anthropomorphic Personification of Mystery, so she's cursed to be a mystery to herself—remembering her true identity triggers the magic that causes her to immediately forget everything.
  • Several varieties of this exist in Blip: both witch spells and vampire breath are capable of erasing memories. K also has dream amnesia, where she regularly has lucid dreams, but can only remember them as she's dreaming.
  • In Bob and George, this is why some characters don't remember encountering their future selves.
  • Schlock Mercenary: Petey (the AI of a space battleship) is ordered to "repress and deny" all instances of the "ghost in the plumbing" incident, so that he doesn't go insane an kill everyone on board.

  • In Gunnerkrigg Court, Coyote removes the memory of Ysengrin's insane attack on Antimony from his mind, against his will. This apparently isn't the first time this has happened, by far.
  • In the Buildingverse both Aziraphale and Crowley (Girls Next Door) and Jareth (Roommates) can do this but in different ways (the former two mind wipe you the later manipulates your time perception the effect is quite similar) and success rate (Jareth failed once). Both comics played with and lampshaded the dubious morality of this.
  • Off-White has a self imposed example. Iki deliberately forgot his life as Skoll, the sun chaser. It took a encounter with his brother Hati for him to remember.
  • morphE begins with 8 normal humans waking up inside crates in the back of a truck. When they discuss their last memories the only interesting thing anyone can remember is that they were working on a missing person investigation and saw a bright blue flash.
  • In Free Spirit, a witch travels to Earth every 100 years to grant a random mortal's wish. Once she finishes granting the wish, and returns to her homeworld, the mortal and anyone else that the witch encountered forgets about meeting her.

  • My Little Pony: The Mentally Advanced Series: In "Rainbow Dash Presents: Spiderses", Big McIntosh, unlike Twilight, doesn't remember that he's in a story being read by Celestia. Celestia Lampshades this.
  • The Alpha AI introduced to viewers in Red vs. Blue: Reconstruction deliberately severed its memories from itself some time ago as a coping mechanism for the torture inflicted upon it by Project Freelancer. Those severed memories formed the Epsilon AI, which merely "suppressed" them (after going insane for a period).
  • The SCP Foundation makes extensive use of amnesia-inducing drugs, which come in (at least) three different flavors: class A, class B, and class C. One erases just memories of the recent past, one erases memories of both recent and medium term past, and one erases pretty much all memories. However, the writers can't agree on whether or not class A is the least powerful or most powerful kind.
    • When being Necessarily Evil to save the world is taken to horrifying extremes, the personnel who Did What They Had To Do can ask to have their memories of what they did wiped.
    • If a Brown Note has only mental effects, there's a good chance the victim can be cured simply by erasing all memories of being exposed to the Brown Note.
    • The Foundation has SCP-055, "the Self-Keeping Secret". As soon as anyone walks out of the room containing SCP-055 they forget any facts about it; same goes for looking away from a photo of it. No one can even remember that they're in possession of an amnesia inducing entity: Foundation personnel will frequently come across the SCP-055 database entry, freak out about the fact that there's an unknown entity right inside their base, and then promptly forget about it.
    • SCP-1655 ("Sorrow Tick"). When it bites a person, everyone that person knows suffers a very selective form of amnesia that applies only to the victim. They don't remember the person, can't sense them in any way, and if touched by the person they feel increasing disgust and discomfort.
  • The reason Myosotis became The Trader of Stories - she has amnesia and wants to discover what she's forgotten and why.
  • Neither Juliana nor Shalise can remember how they ended up in Hell in Void Domain.
  • Welcome to Night Vale: It turns out Cecil can't remember anything of his teen years, including his internship at Night Vale Community Radio and his brother.
  • In Worm, Bonesaw of the Slaughterhouse Nine creates a plague which inflicts retrograde amnesia. She uses it against the heroes and villains that have gathered to destroy the Nine as a final resort. The heroes and villains fall apart as while they remember they're fighting the Nine they don't remember who's in the Nine.
    • Every parahuman sees a vision of two massive entities when they or somebody nearby triggers, though the content varies. Aside from Miss Militia they immediately forget what they saw or even that they saw it. This is a safety measure installed by Scion to prevent humans learning too much about the nature of the entities.
    • The Eden entity had planned to use this as part of her Long Game, removing any memories or thoughts that would make others suspicious of her.

    Western Animation 
  • American Dad!:
    • Stan forgets his anniversary, then tries to avoid a fight by using CIA technology to erase the last 24 hours of Francine's memory. Unfortunately, an error results in her losing 24 years, reverting her to the wild party girl she was before she met him.
    • In another episode, we find out that Stan avoids unpleasant topics by going to a "marriage counselor" who uses hypnosis to erase Francine's memory of whatever she wanted to talk about. Eventually Stan ticks him off and he brings the memories back, kickstarting the plot of the episode.
  • An odd combination with Time Travel: in Danny Phantom, after the evil Danny from the future is defeated, Danny's Secret Identity is revealed, and the whole thing is prevented from happening. The people who already know Danny's secret identity seem to remember the erased events, but the ones who didn't don't.
    • The events were only erased up until Danny took the test it seemed (Jazz is still outside the room, waiting to catch Dark Danny but stops when she sees it's the real one in there).
  • Chip 'n Dale Rescue Rangers had an episode where the Rangers were traveling in France and Dale suffered a blow to the head, whereupon he completely forgot everything about himself and his friends, including his affinity for Hawaiian shirts and practical joking. He was found by a French doppelganger for Fat Cat who turned him into his own personal super-soldier, Ram-Dale. Hilarity Ensues when he finally catches up with the Rangers and tries to kill them. In the end, another blow to the head restores his memory.
  • Code Lyoko:
    • Aelita has no memories of her life before the Supercomputer was turned back on and she woke up on Lyoko—including the fact she was human, thus she's believed to be an AI by everyone including her. It is revealed at the end of Season 2 that XANA had stolen those memories, and uses them to link Aelita's life to the continued working of the Supercomputer.
    • In Season 1 episode "Amnesia", nanomachines created by XANA are causing memory wipes typical for this trope, affecting Ulrich among others.
  • In Codename: Kids Next Door, this is standard procedure for operatives that retire upon turning thirteen years old. (Referred to as "decommissioning".) This is not without justification, seeing as those who have refused the procedure and escaped (such as Numbuh Five's sister Cree) have become some of their worst enemies. The process can be reversed, however, as it was in "Operation: Z.E.R.O." Another episode reveals that not every operative is decommissioned at age thirteen. Some, like Maurice, act as deep-cover agents who are still loyal to the K.N.D. despite not being kids anymore.
  • In Dexter's Laboratory, Dexter is shown erasing his parents' memories of his lab after enlisting their help in defeating a giant monster in the presumptive Grand Finale. Later, his pet monkey erases Dexter's memory of monkey's superpowers. In an earlier episode, Dex accidentally says that he has a lab, prompting Dee Dee to respond "Smooth move, Dexter. Now you'll have to erase Mom and Dad's memories... again!"
  • Captain Hero from Drawn Together appears to be able to do this by stripping unconscious bodies and violating them.
  • Jorgen Von Strangle of The Fairly OddParents! often uses this to erase kids' memories when they reveal the existence of their godparents.
    • As the main character, Timmy Turner would never lose his fairies, so this is used to erase the memory of his friends and family in every episode that, for some reason, he is forced to reveal his fairies existance (most of the times in an attempt to save them and defeat the Big Bad).
  • Parodied in Family Guy when Lois used the neuralizer on Chris when he doesn't stop saying "boobies" after the Griffins visited the nudist family's house.
  • Parodied mercilessly on Futurama whenever Calculon and the cast of All My Circuits take the stage.
    • Also played somewhat-straight in "The Why of Fry," when Nibbler wipes Fry's mind clean of the Brainspawn incident.
  • Gargoyles:
    • In an episode, an alien uses his advanced technology to induce temporary amnesia in Elisa with the intent of erasing what he believes are her false memories of the Gargoyles as her friends (she is told that her true memories will return in a few days). Elisa is then understandably freaked out by her first post-mindwipe encounter with Goliath. Fortunately, her gun wasn't loaded when she pulled it on him. This in turn is the key for Goliath figuring out that something is wrong with Elisa's memory, as she not only didn't recognize him, but she also didn't know her gun was empty, a condition that had existed for at least a month in-story at the time.
    • Puck's first appearance where he eventually reverses the entire city's human/gargoyle status. Everyone thinks their current body is the one they've always had, but all their other memories remain intact and our heroes quickly figure out something is up just by logical reasoning, like the former gargoyles remembering being able to fly and humans-turned-gargoyles insisting they can't despite having wings.
  • Generator Rex
    • Rex has a chronic variety of this. He's lost his memory several times in the past, for reasons that probably relate to his powers. Why this keeps happening has yet to be explained.
    • In "Six Minus Six" Agent Six loses six years of memory saving Rex from a machine that was going to delete Rex's instead (because Rex apparently goes crazy if he resets, and if that happens Six has to kill him). It was never fixed via Reset Button. That means not only does he not remember Rex, Holiday or Bobo, but he doesn't even remember the Event that caused the EVOs (heck, he barely knows what an EVO is). He only stayed with Providence and trying to be the man he used to be because of Rex's unwavering trust him, even as he was six years ago (an unrepentant, mercenary Jerk Ass).
  • Gravity Falls episode "Society of the Blind Eye" gives us a memory erasing gun, which the titular society uses to erase anyone's memories of an encounter with one of the town's anomalies, because they think Ignorance Is Bliss. It's shown that whenever they erase a memory,s one stray thoughts get lost as well; Lazy Susan, after having her memory of the gnomes erased, apparently forgot which gender she was. Old Man McGucket erased his memory so many times that he eventually became the 'Local kook' he is in the present. However, in the end the memory gun becomes the only thing that can destroy Bill Cipher…by erasing the current mind he's inhabiting. Memories can be restored by reminders of those memories, though this can take time.
  • Harvey Birdman, Attorney at Law gave this a Lampshade Hanging: After getting sprayed with "amnesia gas", Harvey wakes up and immediately comments, "What happened? I don't remember anything from specifically the past couple days."
  • Kim Possible avoided this in the episode "Clean Slate", in which Kim has amnesia, and is pretty much square-peg-round-hole moronic until they manage to restore most of her memories.
  • The Legend of Korra: After being eaten by a huge Dark Spirit, Korra washes up on the shores of the Fire Nation with no memories of who she is or how she got there. It took a spiritual healing session for her to remember her purpose and meditation in the Tree of Time to fill the rest of the gaps.
  • Phineas and Ferb: In "Happy Birthday Isabella", it seems like the OWCA has become more frivolous about using memory-erasing technology. Stacy almost fell victim to this.
  • Rick and Morty's Rick has done this several times to Morty.]] They spend a whole episode watching the erased memories. Think of it as "a Clip Show made of...clips you never saaawww!!!"
  • In She-Ra: Princess of Power, it's stated that after baby Adora was kidnapped by Hordak and taken away, the Sorceress erased the Eternia people's memories of the missing Princess; only King Randor, Queen Marlenna, Man-At-Arms and the Sorceress herself know the truth. But then, that's Magical Amnesia for you.
  • The Simpsons:
    • Spoofed on an episode:
    Burns: Fiddle-faddle, everyone knows our mutants have flippers. Oh! I've said too much. Smithers, use the amnesia ray.
    Smithers: You mean the revolver, sir?
    Burns: Precisely. Be sure to wipe your own memory clear when you've finished.
    • Also invoked by Homer in one episode, who wakes up with no memory of only the night before because he drank a special cocktail that erased the last 24 hours from his memories so he could forget the planning his family was doing to create a surprise party for him.
  • Teen Titans plays with this in its Series Finale. Terra comes Back from the Dead and appears to have lost her memory. Possibly a side effect from being brought back from her petrified state. However its implied that she's merely faking amnesia.
  • In TRON: Uprising, it's established that any program who loses their Identity Disc starts having a glitch in the form of temporary bouts of memory loss, and eventually becomes a 'stray' - unable to hold any long-term or short-term memories, and even unable to have a notion of 'self'. Unfortunately for Beck, he has his Disc nicked in the episode "Identity", and is almost tricked into going with the Military before he gets his disc back.
  • Happens in the Young Justice episode "Bereft", where villain Psimon psychically attacks Miss Martian, erasing her memories for the past six months and also erasing everyone's memories of the past six months too since they were all mentally connected with Miss Martian at the time. This leaves Superboy a mindless berserker, Artemis and Megan strangers to everyone else and Robin, Kid Flash and Aqualad ignorant of the mission.

    Real Life 
  • Studies of a drug called U0126 suggest that it might actually be able to induce Laser-Guided Amnesia: see http://www.nature.com/news/2007/070305/full/070305-17.html
  • A common side-effect of the so-called "rape drug" sedatives Rohypnol and GHB (gamma-hydroxybutyrate) is retrograde amnesia, covering the time span the victim was under the drug and usually a short while previous to ingesting it.
    • Likewise, imbibing heroic amounts of alcohol can induce retrograde amnesia — GHB shares many of the biochemical processes, but is far [more?] rapid in effect, which is why it's such an insidious thing to spike a drink with.
    • All benzodiazepines (i.e. drugs in the Valium family, of which Rohypnol is one) can potentially cause retrograde amnesia, but some more than others. Doctors and dentists sometimes deliberately choose Ativan (lorazepam) for its strong tendency in this direction, which makes it ideal for sedating patients prior to unpleasant procedures. Some things you'd be thankful not to recall in great detail.
    • Ketamine, an anesthetic drug used in veterinary medicine, causes amnesia from onset to awakening. This makes it very useful for use in animals (it's hard to treat an animal who has a subconcious aversion towards you after they've been under), but also makes it very illegal to handle without supervision of a licensed veterinarian.
  • Many severe accident victims lose memory of the accident as a result of the trauma. Memories don't quite form instantly, so if something happens to interrupt your brain's function (such as your head slamming into the pavement) the memory of the event will never have a chance to form in the first place.
  • And of course the whole repressed memory thing, where the mind blocks out painful memories so we're only disturbed on the subconscious level. Though the nature of this and even whether or not it exists is controversial. The serious research is being done here.
  • There was once an English footballer named Mills who spent the night in his rival player's house after getting hit on the head. He very specifically couldn't remember the events of the match in which the accident happened... or what team he played for. Everything else was absolutely fine. Fortunately, this didn't last long.
    • Daniel Agger of Liverpool got a nasty concussion during a match against Arsenal. He said he doesn't remember the match at all.
    • Same with the time when John Terry was knocked out after being kicked in the head against Arsenal (who seem to have a thing about causing head injuries) a couple of seasons back, he apparently couldn't remember anything that happened after coming out the tunnel for the second half: https://www.youtube.com/watch?v=8GEB-TYLMmQ
  • Stephen King wrote Cujo during his drinking days. He vaguely remembers writing the book, but only the Broad Strokes of the process. He can't remember the specifics or how he came up with what he feels were the best parts of the story.
  • Unsolved Mysteries once had an amnesia story where a man shows up in a town with absolutely no memory of his past or identity. A man gives him a job, and a customer came in and realized that he was operating an old-style adding machine so efficiently that he must have worked on them professionally in the past, which they used as a first step in figuring out his identity.
  • A woman who had an accident and lost several years of memory, including that of her husband, was the inspiration for the film The Vow.
  • Due to being high as a kite while doing it, Carrie Fisher had no memory of taking part in The Star Wars Holiday Special.
  • Likewise, David Bowie's cocaine addiction was so bad during The '70s that he retained little to no memory of recording his album Station to Station.
  • In a darker example, Mick Foley does not remember the second half of his (in)famous Hell in A Cell match with The Undertaker due to the injuries suffered in that match.
  • Epileptics can sometimes remember up to the very moment the seizure begins, then have a blank during the seizure and for several minutes after. For example, they may not remember such acts as standing up from being trapped in a corner, or even painful actions such as having a nail snapped back into place. Sometimes the only reason an epileptic knows they have had a seizure may be because of these suspicious blanks in their memories.
  • Combined with Implausible Deniability at a number of American congressional hearings. Refusing to answer or being caught lying can have serious consequences, but it's more difficult to prove someone doesn't remember something. Consequently a number of to-remain-nameless officials over the years have gone before congress and the nation and mysteriously forgotten what should be quite memorable actions, people they've met, things they've talked about, and policies of their own department. In some instances these performances would, if taken at face value, raise serious concerns about the mental competence of the individuals in question.
