* At the end of ''Eternal Ring'', [[spoiler:the God-child understanding what death is due to his sorrow over Lyta's death causes him to instantly physically mature into an adult.]]

** ''VideoGame/TheLegendOfZeldaBreathOfTheWild'': Purah, one of the Sheikah's leading magitek researchers, is Impa's older sister, but due to an accident while experimenting with age-reversing tech, she physically resembles a six-year-old girl when Link meets her. By the time ''[[VideoGame/TheLegendOfZeldaTearsOfTheKingdom Tears of the Kingdom]]'' begins, however, Purah is considerably older, more closely resembling her teenage counterpart in ''VideoGame/HyruleWarriorsAgeOfCalamity''. While there was a TimeSkip between games, it was only four or five years at the minimum. Exploring Purah's lab in Hateno, however, Link can find one of her diaries, which reveals she worked out the kinks in this tech and aged herself up to her physical prime.

** ''VideoGame/TheLegendOfZeldaMajorasMask'' lets Link turn Cucco chicks into grown roosters in an instant using the Bremen Mask. This is significant because their owner, Grog, felt that not seeing the Cuccos grow up was the only true regret he had in the face of Termina's imminent destruction. The Fierce Deity Mask, when worn, makes Link taller, look more like an adult, and his battle cries are taken from his adult form from ''Ocarina of Time''.

** In ''Series/PowerRangersZeo,'' Billy got turned into an old man for two episodes. (They were his LAST two episodes. old Billy is TheNthDoctor being used to cover for the actor saying ScrewThisImOuttaHere to behind-the-scenes {{Jerkass}}itude.)

* Vivio turns into an adult in ''Anime/MagicalGirlLyricalNanohaStrikers'' [[spoiler: when the Cradle's defense system forces her to battle Nanoha. She returns to her original age once the [[AppliedPhlebotinum Relic]] inside her is destroyed.]]

* In ''Manga/NegimaMagisterNegiMagi'', in a large ShoutOut to ''Manga/MarvelousMelmo'', Negi's NonHumanSidekick Chamo produces a jar of candies that alter one's age (specifically, the red ones for older, blue ones [[FountainOfYouth for younger]]). Of course, when he uses them, several of his students notice that [[SheIsAllGrownUp He is All Grown Up]] without actually recognizing him.
** Apparently they're based on a spell [[ReallySevenHundredYearsOld Evangeline]] invented to make up for her body's age. Once the gang gets more friendly with her, she provides them apparently for free (the knock-offs are expensive).
* As partially mentioned above, the entire premise of ''Manga/MarvelousMelmo'' is based around age-changing pills: the titular character, a nine-year-old girl, can use some of those to age herself into a 19-year-old girl or an old lady, as well as turn into a baby.

* Of course, we also have to mention [[ComicBook/{{Shazam}} Captain Marvel]], a boy who transforms into an adult superhero. This actually causes a problem when he gets involved with a superheroine his own age, and they have to break up because their teammates, who don't know Marvel's civilian identity, would take it the wrong way. That may have been the origin of Major Might's very brief affair with Amazonia in ''Webcomic/LoveAndCapes''.

* Was once used by Mojo on the ComicBook/NewMutants. It also turned them evil.

* Probably the most famous film example of this trope is the 1988 Tom Hanks movie ''Film/{{Big}}''.
* The former TropeNamer, ''[[Film/ThirteenGoingOnThirty 13 Going On 30]]''.
* The movie ''Film/FreakyFriday2003'', though that's more of a [[FreakyFridayFlip body switch deal]].
** Speaking of which, there were also '80s classics like ''Vice Versa'' and ''Like Father Like Son''.
** And ''Film/SummerSwitch.''
** And, of course, the original ''Film/{{Freaky Friday|1976}}''
* Another one from 1988 - the MadeForTVMovie ''Fourteen Going On Thirty''.
* Italian film ''[[http://www.imdb.com/title/tt0164519/ Da grande,]]'' which actually predates Hanks' ''Big''.
* Creator/AdamSandler's ''Film/{{Click}}'' uses a ratcheting variation, to familiar {{Aesop}}ic ends.

* It's not overnight, but the characters that were teens live temporarily as adults in ''Film/JumanjiWelcomeToTheJungle''

* In the children's book ''Magic by the Lake'' by Creator/EdwardEager, the protagonists are four siblings (three girls, one boy). Two of the girls wish themselves into teenagers and go on a double date, and their brother and sister have to chase them down and undo the wish before the date goes too far.

* In ''Literature/FlossieTeacakesFurCoat'', the eponymous 10-year-old longs for the fun and independence of her older brother and sister. When she puts on her sister's fur coat and does up the magical third button, she becomes the 18-year-old Floz.
** There's a boys' version by the same author, Hunter Davies, entitled ''Literature/ComeOnOssie'', featuring a boy called Oswald who turns into an 18-year-old when he borrows his grandfather's medal. There are several sequels to both books.
* In ''Literature/FiveChildrenAndIt'' by Creator/ENesbit the older four get annoyed with how they have to chase their baby brother around all the time, so they wish him into a grownup. Unfortunately, he didn't learn all of the lessons associated with growing up, such as not being a total prat, and turns out to be even more annoying this way.

* In ''Literature/{{Replica}}'' #16, ''Happy Birthday, Dear Amy'', Amy, Number Seven mysteriously ages into her twenties overnight on her thirteenth birthday. [[spoiler:The rapid aging was caused not by Amy's unusual genetics, but by [[AppliedPhlebotinum some sort of implant]], and she reverts to being a teen [[NoOntologicalInertia when it is destroyed]].]]
* Jake in the ''Literature/{{Animorphs}}'' book ''The Familiar''. He wakes up as a young adult in a world where the Yeerks control the Earth. By the end of the book, he's back to being a young teen, though.

* ''Franchise/StarTrek'':
** First used in the ''Series/StarTrekTheOriginalSeries'' episode "[[Recap/StarTrekS2E12TheDeadlyYears The Deadly Years]]", in which the ''Enterprise'' crew discover a planet where the colonists are afflicted with a rapid aging syndrome and are affected by it themselves.
** ''Series/StarTrekTheNextGeneration'' does the "adults becoming elderly" version a few times:
*** In the "[[Recap/StarTrekTheNextGenerationS2E7UnnaturalSelection Unnatural Selection]]", the ''Enterprise'' receives a distress call from the ''USS Lantree'', where they find everyone dead from rapid aging, and must find the cause before scientists on a research colony suffer the same fate.
*** "[[Recap/StarTrekTheNextGenerationS6E3ManOfThePeople Man of the People]]" has Deanna aging as a side-effect of a psychic ambassador using her energies to influence the outcome of his mission.

* ''[[Series/SabrinaTheTeenageWitch Sabrina The Animated Series]]'' used it in one episode.
* "Brief Candle," from season one of ''Series/StargateSG1'', finds Jack O'Neill infected by Goa'uld nanites which send him flying into old age.
* The TV Show ''BigJohnLittleJohn'' was half this trope and half FountainOfYouth as the titular character switched back and forth between childhood and adulthood at least once an episode.

* In ''Series/PowerRangersDinoThunder'', Cassidy, Devin, and other citizens of Reefside (as well as a pop star) were turned elderly by an youth stealing vacuum monster.
** A donkey-pomegranate-vacuum monster!
** In ''Series/PowerRangersZeo,'' Billy got turned into an old man for two episodes. (They were his LAST two episodes. old Billy is TheNthDoctor being used to cover for the actor saying ScrewThisImOuttaHere to behind-the-scenes {{Jerkass}}itude.)

* The fifth season ''Series/{{Supernatural}}'' episode "The Curious Case of Dean Winchester" involves a poker game played using years as stakes; Dean doesn't fare very well in the game and ages rapidly. He gets better.
* ''Series/{{Smallville}}'' has an episode where two kryptonite-infected teenagers hook up at a party and have a baby...one week later. Clark and Lana end up taking care of the child as he rapidly ages from infant to child before exploding from the effects of rapid aging.

* ''Series/DoctorWho'': Jo Grant is aged into old age when caught in the effect of the battling time flow analogues created by the Master and the Doctor. She gets better.
* ''Series/{{Merlin|2008}}'' used a spell to turn himself into a white-bearded elderly version of himself a few times--and it wasn't just a glamour, as he became noticeably more crotchety and complained about old-person maladies while under the spell. [[spoiler: The last scene of the series finale reveals that he eventually got there the hard way.]]

* Played straight in the video game series ''VideoGame/TheSims''. The characters "poof" from one age group to another once the requisite time has passed. In the first game this only applies to babies becoming children - children never become adults and adults never grow old - but from the second onwards it affects everyone.

* Getting hit by a Magician's spell without armor in ''[[VideoGame/GhostsNGoblins Ghouls 'n Ghosts]]'' turns Arthur into an old man.

* At the end of ''Eternal Ring'', [[spoiler:the God-child understanding what death is due to his sorrow over Lyta's death causes him to instantly physically mature into an adult.]]

* ''WesternAnimation/AmericanDragonJakeLong'': "Young At Heart."

* In the ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' episode [[RecapMyLittlePonyFriendshipIsMagicS9E22GrowingUpIsHardToDo Growing Up is Hard to Do]], the Cutie Mark Crusaders get magically transformed into adult mares when they wish on a magical flower. If Apple Bloom's wish is anything to go by, it made them as old as their sisters.

In ''VideoGame/XenobladeChronicles3'', [[spoiler:the rebuilt Colony Omega rapidly ages the reborn Miyabi, Cammuravi, Mwamba, and Hakt to be near Homecoming]]. The process is seen on-screen when [[spoiler:the reborn Ethel uses it to become physically old enough to fight again]].

* Three episodes of ''WesternAnimation/DextersLaboratory'' deal with the mental mechanics. In one, he wishes to stay up late to watch scary movies, so makes himself older. But thanks to Dee Dee's antics, he overshoots, becomes elderly, and is unable to stay awake to watch. In the second, he is too small in size to ride amusement park attractions, and ends up giving himself a case of [[AttackOfThe50FootWhatever size change]] instead. And in the third, he becomes a teenager... but instead of becoming a handsome lad, he becomes an absolute {{Nerd}} with pimples and crooked teeth.

** Yet another MLP example -- at the climax of the [[Fanfic/RainboomsAndRoyalty Dashverse]] story ''Hot Heads, Cold Hearts, and Nerves of Steel'', [[BigBad Sombra's]] attempt to steal the lifeforce of the kidnapped foals to [[PoweredByAForsakenChild empower himself]] causes them to physically age up at least ten years each, though their mental state stays the same. This gets reversed after Sombra is defeated.

* In the ''WesternAnimation/InvaderZim'' fic ''Fanfic/GazDreamsOfGenie'', Gaz ends up magically aged into adulthood when [[spoiler: her third wish results in her [[BecomingTheGenie becoming a genie]]]].
