I forget how to describe Amnesia Episode here. Where am I?
Amnesia is in a unique position to provide drama for any sort of serial. It's scary to think that one's memories could suddenly be taken away, it can be used to take someone out of the action for a while, or it can be Played for Laughs
, in which case, it will play off of Mistaken Identity
. This is when an entire episode or story arc's plot revolves around a character getting amnesia.
Generally goes hand in hand with Easy Amnesia
and sometimes Identity Amnesia
. Not to be confused with Aesop Amnesia
Anime and Manga
- The One Piece anime has the filler arc " Ocean's Dream" where a seahorse stole all the memories of the protagonists (with the exception of Nico Robin) since they are joined in the Straw Hat crew causing them returnback to their original characterizations. At the end, Luffy defeat the seahorse and all return to normality.
- The Ranma ½ episode "Am I Pretty" has Ranma suffering a more serious than usual bop on the head while in girl mode and forgetting he was ever a boy. The episode plays it for laughs as everyone struggles to deal with a very stereotypically female Ranma who is the polar opposite of their usual self. Fortunately, Status Quo Is God kicks in and everything is back to usual by the episode's end with Ranma's memories restored.
- The Magic Kingdom of Landover series has this as the central plot of The Tangle Box, where King Ben, evil sorceress Nightshade, and dragon Strabo are all trapped in the titular box and stripped of their memories. Made awkward because Amnesia-Ben and Amnesia-Nightshade start to fall in love when they are normally very bitter enemies.
- The Addams Family has the aptly named episode "Amnesia in the Addams Family", in which this happens to Gomez after he gets hit on the head with a club.
- Batman. In almost every episode centering on the supervillain King Tut ("The Curse of Tut"/"The Pharaoh's in a Rut", "The Spell of Tut"/"Tut's Case is Shut", "King Tut's Coup"/"Batman's Waterloo", "The Unkindest Tut of All"), the Egyptologist Professor William McElroy is hit on the head and forgets who he really is, thinking he's the historical King Tut instead. At the end of the episode he's hit on the head again and reverts to his standard personality.
- The Buffy the Vampire Slayer episode "Tabula Rasa" features the Scoobies all getting mass amnesia as a result of a fireplace igniting Lethe's bramble, accidentally causing a Laser-Guided Amnesia spell she crafted to become enhanced.
- Doctor Who: In "Human Nature"/"The Family of Blood", the Doctor voluntarily gave himself amnesia to escape some aliens who are basically psychic bloodhounds. His companion, Martha, has to try and manage the amnesiac Doctor so he doesn't get into trouble until it is safe to put his memories back. Things get complicated when the aliens turn up anyway and the Doctor loses the MacGuffin that contains his memories.
- Gilligan's Island
- In the 1st season episode "Forget Me Not", the Skipper gets amnesia when a pole hits his head. When the Professor tries to cure him with hypnosis, he first reverts him to childhood and then makes him think it's still World War II. Hilarity Ensues.
- In the 3rd season episode "The Second Ginger Grant", Mary Ann is hit on the head and loses her memory, thinking that she's actually Ginger Grant. When the Professor tries to snap her out of it with hypnosis, Gilligan ends up hypnotized into thinking he's Mary Ann. Obviously Played for Laughs.
- Stargate SG-1 episode "Memento Mori" has team member Vala getting amnesia and lost in somewhere in America believing herself to be an ordinary human woman and disbelieving in aliens after she was kidnapped and hooked up to a Mind Probe. Exactly why she defaulted to that state, being a Human Alien, is left unexplained.
- Stargate Atlantis: In "Tabula Rasa", the entire population of the city, save for Pegasus Galaxy natives Teyla and Ronon, wind up with amnesia, of the "constantly forgetting things" variety. On top of this, the episode begins In Medias Res, so it's not clear for some time what's going on.
- Star Trek: The Next Generation has the epsiode "Conundrum" in which the entire crew is given amnesia by an alien posing as the first officer.
- Season 12 of Supernatural has an episode where Dean slowly loses his memory after a witch the Winchester brothers are hunting casts a spell on him. This is Played for Laughs at first but gradually becomes more serious with the progression of the memory loss as the reality of Dean forgetting everything about his loved ones and his concept of himself sets in.
- The Twilight Zone (1959). In the very first episode, "Where is Everybody?", a man finds himself walking along a road with no idea who he is. The episode shows him discovering and exploring a deserted town, trying to find out his true identity and what's going on.
- Code Lyoko had an episode involving one of the main characters getting amnesia, which eventually spreads to the rest of the school. The amnesia is the result of nanomachines being taken over by XANA. The episode is aptly named "Amnesia".
- Family Guy does this in the episode "Big Man on Hippocampus" where Peter gets amnesia and reverts back to living his bachelor lifestyle. Lois spends the episode trying to jog his memory but it seems she fails and Quagmire starts hitting on her. And that is when Peter reveals he got his memory back not long after losing it and was just faking most of it because he enjoyed the opportunity to relive his single days.
- Dastardly and Muttley in Their Flying Machines had an episode in which Dick Dastardly loses his memory after falling out of his plane and landing on his head. Klunk takes command of the Vulture Squadron as he and Zilly try to restore Dastardly's memory.
