* On the first season of ''[[Series/TwentyFour 24]]'', Teri Bauer escapes from the terrorists, only to get into a car accident and become an amnesiac for a few episodes. This is brought on by shock, as she believes her daughter died in the car wreck.
* Liz Lemon's brother on ''Series/ThirtyRock'' averts part three, having suffered a head injury on a skiing trip that stops him from remembering what happened during and after it. His family is careful to pretend that he'll be leaving for it soon. At the end of the episode Liz exasperatedly shouts at him that he's forty, at which point he appears to snap out of it.
** However, given the nature of his injury, it's likely that he would soon forget what she told him.
* ''Series/SixHundredSixtySixParkAvenue'': Danielle seems to have her memory wiped regularly for the last sixty years or so, especially after all the times she's been manipulated into killing someone for Gavin.
* ''Series/{{Angel}}'':
** In the episode "[[http://en.wikipedia.org/wiki/Spin_the_Bottle_%28Angel_episode%29 Spin the Bottle]]", a spell mentally regresses several characters back to their teens, leaving them with no memories of each other. Angel, upon reverting to his mortal identity as Liam, even forgets that he's a vampire! While the others are upset about waking up in a strange place and being inexplicably aged into adults, centuries-old Angel is more freaked out by automobiles and his sudden lack of Irish accent.
** At the end of the fourth season, Angel strikes a deal to magically erase all events related to his son Connor from the minds of his friends and Connor himself. Connor's new, implanted memories are of a suburban human childhood with a {{Muggle}} foster family (who also had their memories altered), rather than one spent in a hell dimension as the mortal son of two vampires. It's even implied that the spell retroactively alters reality to support this new history.
* ''Series/BabylonFive'':
** Sinclair's memories of what happened to him during the Battle of the Line [[spoiler:were erased by the Minbari after they captured and interrogated him.]]
** Artificially induced amnesia is also used on criminals (called the "Death of Personality", the closest thing [=EarthGov=] has to the death penalty), wiping their mind and reprogramming them to be upstanding, law-abiding citizens. First referenced in the episode "The Quality of Mercy", and features in the later episode "Passing Through Gethsemane".
* [[DiscussedTrope Discussed]] on ''Series/TheBigBangTheory'' after Sheldon tries to teach a lecture. Amy suggests destroying the part of the brain containing that memory with a laser. Sheldon declines.
--> '''Sheldon''': No, one small slip of the hand and I'll [[FateWorseThanDeath wind up in Engineering]] making doodads with Wolowitz.
* On ''Series/{{Bones}}'', Dr. Brennan suffers from amnesia about the events of a single night. It may have been caused either by drugs or a [[AWizardDidIt voodoo curse]].



* ''Series/PowerRangersTurbo'': Divatox gets amnesia and starts acting like an ordinary, if uncouth, human -- and she isn't even human, nor has she ever lived like one. Her amnesia was the side-effect of a ''laser'' beam.
** ''Series/PowerRangersRPM'' has Dillon, whose memory was wiped as one of the BigBad's unwilling test subjects prior to the series.
** ''Series/PowerRangersWildForce'': Cole gets amnesia in one episode. He forgets who he is and that he's a Ranger but nothing else.
** ''Series/MightyMorphinPowerRangers'': In one episode, Lord Zedd turned a kaleidoscope into a monster with memory-erasing powers to make the Rangers forget who they are and how to use their powers. They were saved by Bulk and Skull, who tricked the monster into making the monster hit two prisms with his memory-erasing beam, (by passing a prism, it becomes a memory-restoring beam) and restoring the Rangers' memories. The monster made Bulk and Skull forget their recently-acquired knowledge of the Rangers' identities.
* In ''Series/MahouSentaiMagiranger'', a MonsterOfTheWeek puts a spell on TheChick, causing her to forget not only the plot she'd stumbled upon, but ''everything'' to happen since she became a Ranger. Every hour, all new memories are erased, too. Thanks to the broad amnesia, nobody suspects that the intent was to erase ''one specific memory''. Still this trope, since the cutoff point for her memories seems pretty precise.
* ''Series/StargateSG1'':
** Vala loses her memory when a memory-enhancing device malfunctions. Despite the fact that it's mentioned pretty directly at the beginning of the episode that she has very little experience with "normal" Earth-bound human life, her memory loss isn't so severe that she "forgets" how to pass for an earth-born human, or that she ought to have a hard time believing the actual circumstances of her life.
** The same series also gave us "Fallen" in which Daniel, having [[spoiler:[[AscendToAHigherPlaneOfExistence descended from his higher plane of existence]],]] has no idea who he is. This was quite intentional on the part of [[spoiler:the Ascended. Even after Daniel regains memory of his mortal life, his time as an ascended being is very much forgotten, apart from a few glimpses.]]
** There is also an episode where the entire team get their real memories erased and replaced by FakeMemories so that aliens can make them work in a mine.
** And "Fire and Water" from the first season, though in this case the guy in charge overdid it, which the team spotted soon enough.
* ''Series/StargateAtlantis'' also has a hand at this trope in the episode "Tabula Rasa" (not to be confused with the ''Buffy'' episode, though Joss Whedon probably named them both). After contracting an alien virus, the entire Atlantis expedition (save Teyla and Ronon) contracts amnesia, leaving a bunch of bewildered scientists trying to escape soldiers who have forgotten why they're rounding everyone up. The characters also suffered from anterograde amnesia, having some difficulty remembering what they were doing.

Although he falls in love with said wife again, he doesn't actually recover his memory-erasing beam, (by passing a prism, it becomes a memory-restoring beam) and restoring the Rangers' memories.

TheTag being is very much forgotten, apart plot-relevant, Troy listens to a voicemail from Chang sent during the amnesiac period, bragging about how he [[spoiler:slept with Shirley]]. This raises many questions about the events of the night; for instance, why did he call ''Troy?''
* On ''Series/{{CSI NY}}'', Mac has
a few glimpses.realistic version where he cannot recall the events immediately preceeding his being shot. His inability to recall random words and names of places, objects, ect, is a real condition called aphasia, and is laser guided in a sense, but averts most of the usual tropes.
* On the original ''Series/{{CSI}}'', Catherine has a drug-induced incident where [[WakingUpElsewhere she wakes up in a motel without recalling exactly how.

* Happens on ''Series/DeadLikeMe'' if a reaper tries to prove their identity with stories from their past.
* ''Series/DoctorWho''
** There In [[Recap/DoctorWhoS6E7TheWarGames "The War Games"]], Jamie and Zoe are returned to their respective times and have their memories altered so that they don't remember The Doctor as part of his punishment from the Time Lords.
** In the following season during the beginning of the Jon Pertwee era, the Doctor
is exiled on Earth by the Time Lords with his knowledge of time travel wiped from his memory to prevent him from repairing his TARDIS and escaping.
** In [[Recap/DoctorWhoS27E9TheEmptyChild "The Empty Child"]]/[[Recap/DoctorWhoS27E10TheDoctorDances "The Doctor Dances"]], Captain Jack cites this as being the reason he left the Time Agents: two years of his life mysteriously deleted.
** [[Recap/DoctorWhoS30E13JourneysEnd "Journey's End"]] features a particularly depressing example of this -- after becoming overwhelmed by a Time Lord's knowledge, Donna Noble's mind is scrubbed of every single memory of her adventures with the Doctor, undoing all of her character development and restoring her initial self-centered nature and lack of intellectual curiosity. Moreover, the Doctor explains that she must NEVER remember him, or she will die. [[spoiler:Or rather, as shown in [[Recap/DoctorWhoS30E17E18TheEndOfTime "The End of Time"]], have her head go asplody with an energy discharge that protects her, but knocks everyone else out in a half-mile radius. However, it's pointed out that this is a security feature, and she'll still die if she gets her memories back.]]
** Series 6 introduces the Silence, who have the power to make people forget about them as soon as they look away. Which means they could be ''anywhere and everywhere''...'''[[ParanoiaFuel and they are.]]''' They
also leave you with a post-hypnotic suggestion. In [[Recap/DoctorWhoS32E2DayOfTheMoon "Day of the Moon"]], the Doctor manages to use their own ability to foil some of their plans by [[spoiler:recording a video of one of the Silence saying "you should kill us on sight" and then broadcasting it during the Apollo 11 landing; everybody then starts to unconsciously kill the Silence and then forgets about it]].
*** On his quest to be alone the Doctor picks up this trick and uses it to make all of his data in the Inforarium and in all databases that copy from it essentially useless, since it's forgotten as soon as the reader looks away.
** In [[Recap/DoctorWhoS33E1AsylumOfTheDaleks "Asylum of the Daleks"]], [[spoiler:the entire Dalek species]] lose their memories of The Doctor.
** In [[Recap/DoctorWho2012CSTheSnowmen "The Snowmen"]], the Doctor possesses a worm which erases memory. Just touching it will erase
an episode where hour; if it bites you it can erase a lifetime.
** [[Recap/DoctorWhoS34E5TimeHeist "Time Heist"]]:
*** The memory worms return, used by the group to wipe their minds and thus hide their guilt from the Teller.
*** Psi's implants allow him to do this at will. Unfortunately for him, there's no easy restore function, which cost him the memories of his family during an interrogation in order to protect them. He agreed to the heist because the bank holds a device which can restore his memory.
** In [[Recap/DoctorWhoS35E10FaceTheRaven "Face The Raven"]], Rigsy is dosed with Retcon (see the ''Torchwood'' entry above) so he'll forget his being lured to -- and framed for murder on -- the trap street.
** In the Series 9 finale [[Recap/DoctorWhoS35E12HellBent "Hell Bent"]], the climax has the Doctor (who is, at the time, a WoobieDestroyerOfWorlds) preparing to erase someone's memories of him again, this time [[spoiler: Clara Oswald's so he can drop her Only Mostly Dead self on Earth rather than return her to Gallifrey and the moment of her death, which happened two episodes ago]]. The intended victim calls him out on this and he has a HeelRealization. In the end, [[spoiler: he loses his memories of her instead, and while able to reconstruct many of them, he can't recognize her or recall why he went so far for her]].
* Laser guided amnesia is basically
the entire team get their real premise of Creator/JossWhedon's ''{{Series/Dollhouse}}''. They have the technology to erase memories erased and replaced by FakeMemories so that aliens can make them work in then give a mine.
** And "Fire
person FakeMemories, and Water" from the first season, though in this case show proceeds to demonstrate most of the guy in charge overdid it, which conceivable ways of abusing it.
** Controlled amnesia is
the team spotted soon enough.
* ''Series/StargateAtlantis'' also has a hand at this trope
driving plot force in the episode "Tabula Rasa" (not "Needs" (1x08), in which the Dollhouse temporarily erase the memories -- but not the identities -- of Echo (formerly Caroline), Victor (Anthony), Sierra (Priya) and November (Madeline).
** Later, in "Getting Closer" (2x11), [[spoiler: Paul rescues November from another Dollhouse in UsefulNotes/WashingtonDC and takes her back
to be confused Los Angeles, but is allowed to keep her there only on condition of restoring her to her imprint of "Mellie" - the woman Paul fell in love with but deserted after learning she was a doll programmed to spy on him. "Mellie" is restored, but all memory of the ''Buffy'' episode, though Joss Whedon probably named them both).

* ''Series/{{Torchwood}}'': {{Retcon}}, a drug that not only induces specific partial amnesia but encourages the recipient's mind to "fill in the blanks", which usually prevents the victim from realizing they've been "retconned". A single image, say an alien murder weapon, can trip the amnesia if you're clever.
** Also in ''Torchwood'', Gwen [[spoiler:ends up admitting her affair with Owen to Rhys and after clearing her conscience, gives him a drink with Retcon in it, so he doesn't remember.]]
** In an aversion of #4, it's revealed late in the first series that [[spoiler:Suzie Costello, before she died, had been going to a support group and gushing to one man about everything she needed to get off her chest from her job, then retconning him ''every week, for years.'' Given that {{retcon}} isn't generally applied more than once to anyone for fear of unknown overdose effects, and the guy is pretty nuts by the time they find him, this is horrifying.]]
* ''Series/{{Smallville}}'' erases the memories of anyone who finds out about Clark's real identity. Really. It doesn't matter how you found out, what you saw, or what he did under the influence of this week's {{phlebotinum}}. Your memory ''will be wiped'', often without explanation. Amnesia is the Smallville Flu.
** In the very first episode, Jeremy forgets everything after [[PsychoElectro electrocuting]] [[HoistByHisOwnPetard himself]].
** Lana, Jonathan and Pete forget everything after [[spoiler:they are cured of the nicodemus flower's toxin.]]
** Chloe forget all about Clark's secret after [[spoiler:the parasite inside her is removed.]]
** Judging by what happened to Lois's memory after her love potion wore off, the writers seem to think that all drugs erase your memory. Really, a love potion does that? You wake up next to someone with no clue as to what happened? Popping paracetamol must be a risky business in Smallville.
** We've lost count of the number of times a bump on the head has wiped Lana's memory of seeing some super heroics.
** However, one notable exception to all this is Javier Ramirez in ''Subterranean'', who does find out and does not get amnesia by the end of the episode.
** This was used often in the first and second season to allow the advertisers to imply that the final conflict between Lex and Clark was at hand. It never was.
** In more recent seasons, nearly every important cast member but Lex is in the know, so there's less need for this. The superhero cameos learn quickly, but keep the secret since they're on the same side.
** In a rare example of plot-central, rather than "convenient", amnesia, Season 3 has Lex undergo a mind-wipe disguised as electroshock therapy for his supposed schizophrenia. The writers apparently didn't know that electroshock therapy is an extreme treatment for depression, not schizophrenia, and that it only removes ''minutes'' of memory, not months.
** Lois and Sheriff Adams see Clark use his powers in "Blank". Luckily, the [[DifferentlyPoweredIndividual metahuman]] he just met can erase the last few moments of someone's memory and he owes Clark a favor.
** In ''Freak'', Daniel [[spoiler:and later Chloe]] has their memory of Lex's secret lab wiped after being experimented on. [[spoiler:After the viewers see the trauma Chloe goes through as Lex's lab rat, it's possibly [[IgnoranceIsBliss best for her to forget]].]]

* ''Series/{{Angel}}'':
** In the episode "[[http://en.wikipedia.org/wiki/Spin_the_Bottle_%28Angel_episode%29 Spin the Bottle]]", a spell mentally regresses several characters back to their teens, leaving them with no memories of each other. Angel, upon reverting to his mortal identity as Liam, even forgets that he's a vampire!

* On the first season of ''[[Series/TwentyFour 24]]'', Teri Bauer escapes from the terrorists, only to get into a car accident and become an amnesiac for a few episodes. This is brought on by shock, as she believes her daughter died in the car wreck.
* In the ''Series/KateModern'' episode "I can't remember anything!", Kate realises she has no memories of anything that happened that day, the 3rd of August 2007.
* In the first season of ''Series/{{Lost}}'', Claire returns from her kidnapping with no memories of anything after the season-starting plane crash. (Which was a month or so according to "in-show" time.) The memories came trickling back, and she finally remembered what the Others did to her (which included pumping her full of drugs, making the amnesia a little more realistic).



* ''Series/StarTrekTheOriginalSeries'':
** Episode "Requiem for Methuselah". Spock uses the Vulcan Mind Meld to remove Kirk's memories of Rayna Kapek to relieve his grief over her death. Spock's gesture (literally) is a CrowningMomentofHeartwarming. Perhaps because it's one of the rare instances when Kirk seems truly and deeply affected by the loss (and you get the feeling Spock -- at best -- has the ability to ease Kirk's pain somewhat, rather than perform a truly Laser Guided procedure). As for [[HoYay other interpretations]] of the scene: well, those are inevitable...
** See also the episode "The Paradise Syndrome", where Kirk's memory is zapped by an alien device, to later be restored by a mind meld with Spock.
* ''Series/StarTrekTheNextGeneration'':
** Episode "Conundrum". The ''entire crew'' suffers from LaserGuidedAmnesia, forgetting who they are, but not their skills. Only the audience knows that the first officer is out of place. This effect is intentional, though, as part of an alien plot.
** In a similar episode, "Clues", the entire crew realizes after an unexplained wormhole jump that they are missing one day of memory. Subtle hints suggest that Data knows more about what was going on, but all of the clues lead to a real conspiracy theory. [[spoiler:The ''Enterprise'' had encountered extremely xenophobic aliens who did not want their existence known. To end hostilities, Picard allowed their memories of that day to be wiped. Data, the only one unaffected by the process, was commanded never to reveal what happened.]]
* ''Series/StarTrekVoyager'':
** A two-part episode, "Workforce", was based on this. Almost the entire crew was captured by aliens and put to work on some planet after having their memories scrambled.
--->'''[[http://docohobigfinish.blogspot.co.uk/2012/10/voyager-season-seven.html Doc Oho]]''' ''If you were going to wipe Sevenís mind and give her a job, then an Efficiency Monitor is just about the perfect fit! Tuvok is a riotous sort of fellow who belly laughs when he [[DontExplainTheJoke spots the logic in jokes]]! Canít we just stay on this planet? These are genuinely more likable versions of all of the regular characters!''
** In another episode, some Hirogen capture the ship, suppress almost everyone's memories, implant false memories, and hunt the crew through a variety of holodeck simulations.
** A justified example with the Doctor, who, being a hologram, is a computer program. When an experience ends up nearly causing a cascade failure (i.e. total collapse of AI personality), Janeway has his memories of the experience wiped, as well as all the logs. All crewmembers are ordered never to mention it to the Doctor. However, he later starts finding clues, such as a stitch of his own invention that he applied to Harry Kim during this event, or a picture of a crewmember he doesn't recognize. This nearly leads to another cascade failure.
** "Unforgettable". The humanoid Ramura race give off a pheromone that has an odd effect on other beings. A few hours after the Ramura leaves their presence, the other being completely forgets ever having met them.
* ''Series/StarTrekEnterprise'' did a good episode about anterograde amnesia caused by alien parasites. T'Pol had to tell Archer the whole story again each day for years. Good thing for Vulcan patience.
* The amnesia pills used in the BritishTV series ''Series/{{UFO}}''.
** Used with a twist in one episode, in which a woman who wants to kill her husband gets the amnesia treatment after killing a UFO pilot instead - but the amnesia doesn't affect her desire to kill her husband, and SHADO can't interfere without revealing their secrets.
* In ''Series/SabrinaTheTeenageWitch'', mortals who are exposed to magic will often be forced to lose all memories of the magic. Sabrina's early season love interest, Harvey, had his memory erased for this reason so many times that he eventually became immune to the memory-erasing spell, forcing Sabrina and her aunts to bring him in on TheMasquerade.
* Liz Lemon's brother on ''Series/ThirtyRock'' averts part three, having suffered a head injury on a skiing trip that stops him from remembering what happened during and after it. His family is careful to pretend that he'll be leaving for it soon. At the end of the episode Liz exasperatedly shouts at him that he's forty, at which point he appears to snap out of it.
** However, given the nature of his injury, it's likely that he would soon forget what she told him.
* On ''Series/{{Bones}}'', Dr. Brennan suffers from amnesia about the events of a single night. It may have been caused either by drugs or a [[AWizardDidIt voodoo curse]].
* Used in the series finale of ''Series/ThirdRockFromTheSun'' -- with permission, Dick conks Mary over the head with an alien device that somehow [[WillingSuspensionOfDisbelief selectively erases her memory]] of their relationship, so that she can go on without him on Earth.

to:

* ''Series/StarTrekTheOriginalSeries'':
''Series/KamenRiderDecade'': Tsukasa has this. Subverted as he knows his name, the fact that he is from another world, and recognizes specific people and places in detail.
** Episode "Requiem Averted in ''Series/KamenRiderKiva'', in which Wataru finds himself taking care of an Amnesia victim who can't remember his life, but also can't remember basic stuff like how to use chopsticks, what is and isn't edible, or even that fish survive in the water (when we first see him, he's taking carp out of a river to "save them from drowning.") Aside from speaking normally, he's basically regressed back to an infant. This is mostly played for Methuselah". Spock uses laughs, though.
** [[Series/KamenRiderDenO Kamen Rider Zeronos]] has
the Vulcan Mind Meld power to remove Kirk's [[InvokedTrope invoke this]] [[InvertedTrope on others]] by simply ''transforming''. The explanation is that his [[TransformationTrinket Zeronos cards]] run on people's memories of Rayna Kapek to relieve himself. After he's done using the card, that person forgets who he is. [[spoiler: The Zeronos Cards that enable his grief over her death. Spock's gesture (literally) is a CrowningMomentofHeartwarming. Perhaps because it's one of [[SuperMode Zero Form]], on the rare instances when Kirk seems truly and deeply affected by the loss (and you get the feeling Spock -- at best -- has the ability to ease Kirk's pain somewhat, rather than perform a truly Laser Guided procedure). As for [[HoYay other interpretations]] of the scene: well, those are inevitable...

happened to Lois's memory after her love potion wore off, the writers seem to think that all drugs erase your memory. Really, a love potion does that? You wake up again two months later next to someone with no clue as to what happened? Popping paracetamol must be a risky business in Smallville.
** We've lost count of the number of times a bump on the head has wiped Lana's
memory of seeing some super heroics.
** However, one notable exception to all this is Javier Ramirez in ''Subterranean'', who does find out and does not get amnesia by the end of the episode.
** This was used often in the first and second season to allow the advertisers to imply that the final conflict between Lex and Clark was at hand. It never was.
** In more recent seasons, nearly every important cast member but Lex is in the know, so there's less need for this. The superhero cameos learn quickly, but keep the secret since they're on the same side.
** In a rare example of plot-central, rather than "convenient", amnesia, Season 3 has Lex undergo a mind-wipe disguised as electroshock therapy for his supposed schizophrenia. The writers apparently didn't know that electroshock therapy is an extreme treatment for depression, not schizophrenia, and that it only removes ''minutes'' of memory, not months.
** Lois and Sheriff Adams see Clark use his powers in "Blank". Luckily, the [[DifferentlyPoweredIndividual metahuman]] he just met can erase the last few moments of someone's memory and he owes Clark a favor.
** In ''Freak'', Daniel [[spoiler:and later Chloe]] has their memory of Lex's secret lab wiped after being experimented on. [[spoiler:After the viewers see the trauma Chloe goes through as Lex's lab rat, it's possibly [[IgnoranceIsBliss best for her to forget]].]]

** The same series also gave us "Fallen" in which Daniel, having [[spoiler:[[AscendToAHigherPlaneOfExistence descended from his higher plane of existence]],]] has no idea who he is.

After contracting an alien virus, the entire Atlantis expedition (save Teyla and Ronon) contracts amnesia, leaving a bunch of bewildered scientists trying to escape soldiers who fail have forgotten why they're rounding everyone up. The characters also suffered from anterograde amnesia, having some difficulty remembering what they were doing.
* ''Series/StarTrekTheOriginalSeries'':
** Episode "Requiem for Methuselah". Spock uses the Vulcan Mind Meld
to enter Brakebills remove Kirk's memories of Rayna Kapek to relieve his grief over her death. Spock's gesture (literally) is a CrowningMomentofHeartwarming. Perhaps because it's one of the rare instances when Kirk seems truly and deeply affected by the loss (and you get the feeling Spock -- at best -- has the ability to ease Kirk's pain somewhat, rather than perform a truly Laser Guided procedure). As for [[HoYay other interpretations]] of the scene: well, those are inevitable...

** A two-part episode, "Workforce", was based on this. Almost the entire crew was captured by aliens and put to work on some planet after having their memories scrambled.
--->'''[[http://docohobigfinish.blogspot.co.uk/2012/10/voyager-season-seven.html Doc Oho]]''' ''If you were going to wipe Sevenís mind and give her a job, then an Efficiency Monitor is just about the perfect fit! Tuvok is a riotous sort of fellow who belly laughs when he [[DontExplainTheJoke spots the logic in jokes]]! Canít we just stay on
this fails planet? These are genuinely more likable versions of all of the regular characters!''
** In another episode, some Hirogen capture the ship, suppress almost everyone's memories, implant false memories,
and she remembers enough to become obsessed hunt the crew through a variety of holodeck simulations.
** A justified example
with doing magic.
* In ''Series/{{Shadowhunters}}'', Jocelyn hired Magnus to erase Clary's
the Doctor, who, being a hologram, is a computer program. When an experience ends up nearly causing a cascade failure (i.e. total collapse of AI personality), Janeway has his memories of the experience wiped, as well as all the logs. All crewmembers are ordered never to mention it to the Doctor. However, he later starts finding clues, such as a stitch of his own invention that he applied to Harry Kim during this event, or a picture of a crewmember he doesn't recognize. This nearly leads to another cascade failure.
** "Unforgettable". The humanoid Ramura race give off a pheromone that has an odd effect on other beings. A few hours after the Ramura leaves their presence, the other
being attacked completely forgets ever having met them.
* ''Series/StarTrekEnterprise'' did a good episode about anterograde amnesia caused
by alien parasites. T'Pol had to tell Archer the whole story again each day for years. Good thing for Vulcan patience.
* ''{{Series/Supernatural}}'':
** After Dean nearly gets Ben and Lisa killed one last time, he asks Castiel to do him
a monster when favor by wipe any memory they ever had of him.
** It's revealed in season eight that upper-level angels have been coercing other angels for centuries and then violently removing any memory of the coercion ever happening. In fact, they remove any memory that the upper-level angels even exist.
** In season six, Sam has a wall in his head separating him from all the bad things that happened in the eighteen months after his body was saved from Hell while his soul spent quality time with TheDevil. The main symptom of this wall is that he neither remembers the horrors he committed while soulless nor the ones he endured while in Hell.
* Used in the series finale of ''Series/ThirdRockFromTheSun'' -- with permission, Dick conks Mary over the head with an alien device that somehow [[WillingSuspensionOfDisbelief selectively erases her memory]] of their relationship, so that
she was can go on without him on Earth.
* ''Series/{{Torchwood}}'': {{Retcon}},
a child.drug that not only induces specific partial amnesia but encourages the recipient's mind to "fill in the blanks", which usually prevents the victim from realizing they've been "retconned". A single image, say an alien murder weapon, can trip the amnesia if you're clever.
** Gwen [[spoiler:ends up admitting her affair with Owen to Rhys and after clearing her conscience, gives him a drink with Retcon in it, so he doesn't remember.]]
** In an aversion of #4, it's revealed late in the first series that [[spoiler:Suzie Costello, before she died, had been going to a support group and gushing to one man about everything she needed to get off her chest from her job, then retconning him ''every week, for years.'' Given that {{retcon}} isn't generally applied more than once to anyone for fear of unknown overdose effects, and the guy is pretty nuts by the time they find him, this is horrifying.]]
* Played straight on ''Series/{{Tracker}}''. Cole is shocked by his collector device due to an instability, and loses all memory of who and what he is, until Mel helps him restore it.
* The amnesia pills used in the BritishTV series ''Series/{{UFO}}''.
** Used with a twist in one episode, in which a woman who wants to kill her husband gets the amnesia treatment after killing a UFO pilot instead - but the amnesia doesn't affect her desire to kill her husband, and SHADO can't interfere without revealing their secrets.



* ''Series/EmeraldCity'':
** Lucas can't remember who he is, or anything before his attempted crucifixion. [[Recap/EmeraldCityS1E6BeautifulWickedness "Beautiful Wickedness"]] reveals that his amnesia [[spoiler:was deliberately magically induced]].
** In [[Recap/EmeraldCityS1E10NoPlaceLikeHome "No Place Like Home"]], Tip punishes Eamonn for the murder of [[spoiler:Tip's parents, by erasing the memory of Eamonn from his wife and daughter]].



** The Foundation has [[http://www.scp-wiki.net/scp-055 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.\\\

** [[http://www.scp-wiki.net/scp-1655 SCP-1655 ("Sorrow Tick").]] When the SCP-1655 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.
