History Main / PersonalitySwap

'''Jade:''' ''[gives Jackie an "Uncle smack"]'' I do not know such spells. Jade has Uncle's ''[[LifeEnergy chi]]'', not his ''brain''.\\

* In an episode of TheLionKing spinoff "Timon and Pumbaa", the titular pair think they're going to die as a result of eating poison bugs. During their "last days", the pair undergo a personality swap-the usually [[JerkAss selfish and greedy]] Timon gives away all his earthly posessions and finds joy in kindness and generosity, while the formerly kind-hearted Pumbaa becomes self-centered and vain, wanting to live it up before he goes out. Naturally, when it is revealed that death isn't imminent, the pair revert to their usual personalities.

* Parodied in the FourthWallMailSlot in one volume of ''{{Eyeshield 21}}'' - A reader asks what would happen if [[HeroicSociopath Hiruma]] and [[TeamMom Mamori]] switched personalities. They come to the conclusion it's best the way it is.

* An episode of ''SabrinaTheTeenageWitch'' has this happen to Zelda and Hilda who willingly purchase some pairs of magical 'Walk in my Moccasins' to get a better perspective on each other.

* This actually ''is'' involved with a FreakyFridayFlip in TheWorldGodOnlyKnows. [[spoiler:Yui and Keima]] switch bodies but otherwise act like their normal selves...until later in the arc when they begin assuming the personality of the other person when [[spoiler:Keima gets flustered by close physical contact with his own body like Yui did not long before and Yui starts picking up on masculine pronouns and things.]] Things go back to normal before the situation can degenerate any further, however. The implication is that [[spoiler:the runaway spirit over time would have basically [[TheMindIsAPlaythingOfTheBody modeled them into the bodies they possessed]] in an attempt to gain its resurrection.]]

* One episode of ''TheSimpsons'' has Bart and Lisa swap social positions (if not total personalities) after a IneptAptitudeTest. Bart becomes the good student when he finds that his career path is in law enforcement and is given the Hall Monitor position. Lisa, finding her path to be as just a homemaker, starts acting out and hanging with the bad girls. Their personalities don't ''exactly'' switch, however: Bart basically becomes a justified thug while Lisa uses her intelligence to best effect when rebelling against everybody. The Status Quo gets restored when Bart takes the fall for Lisa's theft of the teachers' guides because even he recognizes that she has a better future than he does.

* ''DragonTales'' did this to Zak and Wheezie in one episode via a magic statue. As they share the same body, the FreakyFriday plot wouldn't be an option anyway.
* In the ''KimPossible'' episode "Bad Boy", AppliedPhlebotinum causes {{Sidekick}} Ron to gradually become evil while MadScientist Drakken turns good.

* This happens in an episode of ''SpongeBobSquarePants'' where Squidward gets electrocuted by his electric fence [[LightningCanDoAnything and gets a personality similar to SpongeBob's]], and then at the end of the episode where [=SpongeBob=] gets electrified by the same fence and ends up with a personality like Squidward's.

* The ''EdEddNEddy'' episode "Mirror, Mirror on the Ed" has the Eds daring each other to act like another Ed. [[TheDitz Ed]] imitates Eddy ("I'll do anything for cash, 'cause I'm short."), [[TheSmartGuy Edd]] imitates Ed ("Gravy!"), and [[{{Schemer}} Eddy]] imitates Edd ("Oh, the insanitary! My skinny arms cannot bear the weight.")
* ''TimeSquad'' does this without a plot device at all- after a fierce argument, the fussy, cultured Larry and overly manly Buck cordon off the space station to avoid each other, only to realise that everything they like is on the other one's side of the station. So out of boredom, Buck starts learning gourmet cooking, while Larry is irresponsible with a {{BFG}}.
* ''PhineasAndFerb'' played with this in one episode. Everyone's roles and {{Catch Phrase}}s were shuffled around. Doofinshmirtz built a giant city (with Norm as the guy who sat around and occasionally spoke), while Vanessa (who underwent a ClothingSwitch with Candace to Lampshade the whole thing) tried to tell her mom. He even expected Perry to show up ("Hey, where's Perry the Platypus?"), but Perry was unable to get to Major Monogram because of a pet-cone. Meanwhile, Phineas built a machine that would spread a rainbow over [[LargeHam The Entire TRI-STATE AREA!!!]], only for Perry, who was unable to see past pet-cone, hit the [[ContractualGenreBlindness self-destruct button on it]]. He sneezes ("Bless you, Perry the Platypus!"), and Phineas removes the cone. Perry then rushes to the docks, where Doofenshmirtz's city has sunk (before Vanessa could get her mom there). Doof delivers the "Oh, there you are Perry The Platypus." and Candace and Vanessa meet up at a store, and presumably switch clothes offscreen.

* Happened in one ''Literature/LabyrinthsOfEcho'' {{flashback}}-sequel when Max needed to get some self-control very quick and Shurf Lonli-Lokli with his current LawfulStupid personality keeping his old ChaoticStupid personality down wanted some rest. So when Max mentioned that it would be cool to "feel myself in your skin", Shurf, as the biggest BadassBookworm around, knew about an old spell that can do this. The Exchange of Ulviar, or Candle of Fittekh exchanges "Shadows" -- no one yet managed to articulately explain what these are, but they can be contacted and manipulated and this spell effectively swaps the participants' personalities and talents. It got two names after the inventors and first known users, an ancient elven king and his court healer. The legend says that Ulviar got Healer's call and Fittekh got ambitions and enough of political talents to halfway organize a coup before the spell's duration ended, leaving the king with new respect to the healer's altruism and the healer impressed by the self-restraint of his king who normally didn't act as HotBlooded as was inclined.

* Happens in an episode of ''{{Seinfeld}}'' to Jerry and Kramer when they switch apartments.

* On ''NewsRadio'', meek man-child Matthew becomes the office jerk after he asserts himself to Bill (by punching his lights out), who in turn takes Matthew's place as the meek one. [[StatusQuoIsGod The status quo]] is restored when Bill, trying to defend Matthew, accidentally slaps him in the face, causing Matthew to snap out of his power trip.

* In ''QuantumLeap'', a freak accident switches Sam and Al's roles, with Al now trapped in time and Sam as a computer projection finding advice and information. The switch also makes Al more virtuous and Sam more lecherous, confounding them both.
* On ''ThirtyRock'', when Liz gets a job hosting her own talk show, it gives her AcquiredSituationalNarcissism and she starts acting like a delusional diva... in other words, like Jenna. Meanwhile, Frank is promoted to show runner on TGS and starts acting (and looking!) like Liz.
* Happened a few times on ''HomeImprovement''. Every so often Tim would shift character positions with someone else as they act more impulsive like Tim would normally. When Wilson was thinking of moving back to where he use to live with his (now deceased) wife because her memory was fading, they actually swapped sides of the fence as Tim gives him advice on how to remember departed loved ones. When Al took on as a guest host for a cooking show and Tim took up as a dedicated assistant, Al ended up being arrogant and refused the practical advice Tim would give.

* Apparently, one of the plans in CrashTwinsanity, was to make it so that when they go to the [[{{BizarroWorld}} Tenth Dimension]], Crash and Cortex switch personalities, unfortunately, this was removed from the game.

* On ''[=~30 Rock~=]'', when Liz gets a job hosting her own talk show, it gives her AcquiredSituationalNarcissism and she starts acting like a delusional diva... in other words, like Jenna. Meanwhile, Frank is promoted to show runner on TGS and starts acting (and looking!) like Liz.

* The 2nd part of the ''StarTrek'' audio book ''Spock VS Q'' has this befall the titular characters after a casual handshake. [[HilarityEnsues Utter hilarity ensues.]]

* In the ''StarTrekTheNextGeneration'' episode "Transfigurations" Dr. Crusher finds that to save a shuttle crash victim she needed someone to volunteer a neural link to help regulate their brain functions. Geordi volunteers and because the individual was undergoing a type of [[AscendToAHigherPlaneOfExistence Ascending to a Higher Plane of Existence]] transformation the leftover impression gave Geordi an amazing boost in confidence especially with romantic pursuits.

* Apparently, one of the plans in Crash: Twinsanity, was to make it so that when they go to the [[{{BizarroWorld}} Tenth Dimension]], Crash and Cortex switch personalities, unfortunately, this was removed from the game.

* ''What's New, ScoobyDoo?'': In "A Terrifying Round with a Menacing Metallic Clown": Due to Velma's [[WhyDidItHaveToBeSnakes coulrophobia]] and Shaggy's desire to win a mini-golf tournament, meaning nothing is going to stop him, they switch personas (and positions within the Mystery Inc. gang) for an episode when a MonsterClown shows up... mostly.

* An episode of Rugrats uses a variation on ClothesMakeTheManiac. Whilst in the park, Chuckie and Angelica manage to switch shoes. Chuckie slowly becomes more bossy and condescending to poor Tommy, while Angelica mellows out and become afraid of everything. [[spoiler: However, the whole ordeal turns out to be AllJustADream that Tommy had after hearing his dad comment 'I'd hate to be in that guy's shoes,' whereafter Angelica lied and said that if you put on someone else's shoes, you become that person.]]

* ''AmericanDad'': In "Rough Trade", Stan is sentenced to house arrest for driving drunk, and Roger sets out to prove he can be a provider. Roger becomes the family role model, Stan becomes the obnoxious drunk.

* This actually ''is'' involved with a FreakyFridayFlip in TheWorldGodOnlyKnows. [[spoiler:Yui and Keima]] switch bodies but otherwise act like their normal selves... until later in the arc when they begin assuming the personality of the other person when [[spoiler:Keima gets flustered by close physical contact with his own body like Yui did not long before and Yui starts picking up on masculine pronouns and things.]] Things go back to normal before the situation can degenerate any further, however. The implication is that [[spoiler:the runaway spirit over time would have basically [[TheMindIsAPlaythingOfTheBody modeled them into the bodies they possessed]] in an attempt to gain its resurrection.]]

** Also happened, thanks to sunspots, with Sabrina and Libby. However, they did not act ''exactly'' like each other -- Libby went from being, well, TheLibby to a FriendToAllLivingThings, and Sabrina went from being her normal self to militaristic would be EvilOverlord with plans to TakeOverTheWorld (with a little prodding from Salem).

* ''Dragon Tales'' did this to Zak and Wheezie in one episode via a magic statue. As they share the same body, the FreakyFriday plot wouldn't be an option anyway.
* In the ''KimPossible'' episode ''Bad Boy'', AppliedPhlebotinum causes {{Sidekick}} Ron to gradually become evil while MadScientist Drakken turns good.
** In the PostScriptSeason episode ''Stop Team Go'', the same AppliedPhlebotinum is now turned into a MirrorMoralityMachine and causes instant [[CharacterAlignment alignment]] switches. Team Go becomes evil and [[TheDragon Shego]] turns good to become Kim's best friend; The [[FoeYay KiGo]] [[LesYay shippers]] {{squee}} as their dreams almost become {{canon}}.
* ''{{Inhumanoids}}'' had Magnokor and Metlar switch alignment after the former boosted their magnetic powers through a [[GreenRocks boulder of galvacite]] to finally defeat their arch-enemy.

-- ''JackieChanAdventures'', "Chi of the Vampire"

* In the ''JackieChanAdventures'' episode "Chi of the Vampire" a ChineseVampire absorbed several characters' [[LifeEnergy chi]]; which mean they needed 'chi transfusions'. This led to Tohru becoming like Jade, and Jade becoming like Uncle, providing the above quote.

* This actually ''is'' involved with a FreakyFridayFlip in TheWorldGodOnlyKnows. [[spoiler:Yui and Keima]] switch bodies but otherwise act like their normal selves... until later in the arc when they begin assuming the personality of the other person when [[spoiler:Keima gets flustered by close physical contact with his own body like Yui did not long before and Yui starts picking up on masculine pronouns and things.]] Things go back to normal before the situation can degenerate any further, however. The implication is that [[spoiler:the runaway spirit over time would have basically modeled them into the bodies they possessed in an attempt to gain its resurrection.]]

** A similar thing happened in another episode where the Simpsons got a pool and Bart ended up breaking his arm and had to be cooped up in the house all summer. Lisa became wildly popular with the other kids while Bart became bitter and reclusive. However, Lisa's popularity fades when Martin gets an even better pool, and the Status Quo is restored.

[[AC:LiveActionTV]]

[[AC:Manga & Anime]]
* One confusing episode of ''MartianSuccessorNadesico'' centered around several of the characters' minds being linked together by the enemy robots (or something like that). While they were connected, they were unable to consciously control their own bodies, which were then taken over by their suppressed personality traits. It led to ActionGirl Ryoko cowering in fear, MsExposition Inez refusing to explain things, and eternal sadsack Jun [[CrowningMomentOfFunny grabbing a machine gun and running around in search of things to shoot.]]
* Parodied in the FourthWallMailSlot in one volume of ''{{Eyeshield 21}}'' - A reader asks what would happen if [[HeroicSociopath Hiruma]] and [[TeamMom Mamori]] switched personalities. They come to the conclusion it's best the way it is.
* ''AxisPowersHetalia'' has [[StraightMan Germany]] and [[TheDitz Italy]] try and act like each other in one comic.
* ''MariaHolic'' has Matsurika use SleepLearning to change Kanako from a giddy, rambling idiot into someone closer to a ClassRepresentative. To Mariya's surprise, while Kanako's personality is much more stubborn, her [[LovableSexManiac perversions]] haven't changed a bit.
* The third episode of ''MakaiSenkiDisgaea'' has Etna and Flonne exchanging everything but their actual identity. [[FetishFuel This includes their clothes]].

* Apparently, one of the plans in Crash: Twinsanity, was to make it so that when they go to the [[{{BizarroWorld}} Tenth Dimension]], Crash and Cortex switch personalities, unfortunately, this was removed from the game.

** Additionally, ''The New Adventures Of Winnie The Pooh'''s episode "Sham Pooh" features Pooh losing his appetite, causing the gang to suspect that he's not, in fact, Pooh. It is then determined that Owl is actually Pooh, Gopher is Owl, Piglet is Gopher, and Rabbit is Piglet. The characters act accordingly up until Pooh starts eating honey again.

* The third episode of the ''{{Disgaea}}'' anime has Etna and Flonne exchanging everything but their actual identity. [[FetishFuel This includes their clothes]].
