%%ZCE * Dave Bowman in ''[[Film/TwoThousandTenTheYearWeMakeContact 2010]]''.

* Foster from Keith Laumer's ''[[http://www.webscription.net/10.1125/Baen/0743488555/0743488555.htm A Trace of Memory]]'' goes from an old man to a youth in the space of an evening... but loses his memory in the process. It turns out this happens to him [[spoiler: indeed, his entire species]] on a regular basis. The plot is motivated by his friend's quest to restore Foster's memory, and TheReveal has to be seen to be believed: it's one of the cheekiest [[TomatoSurprise twist endings]] in all of literature - cleverly foreshadowed, but still quite shocking in its chutzpah.

%%* ''ComicBook/{{Shazam}}''. Ten year old Billy can transform into Captain Marvel by saying a magical word.

%%* Similar to ''ComicBook/{{Shazam}}'', ComicBook/TheUltraverse's ''Prime''. He also had a DistaffCounterpart called "Elven".

** Miss Hinako has the default form of a girl of about eleven years, and turns into a [[MsFanservice curvaceous]] twenty-something by [[EnergyAbsorption absorbing]] LifeEnergy, {{Battle Aura}}s and KiAttacks. Although it's never addressed in the source material, it seems likely that her adult form is her true age, and her child form is the result of slowed aging due to Happosai giving her EnergyAbsorption powers via altering her metabolism with {{Pressure Point}}s to cure a childhood illness.

* Link in ''VideoGame/TheLegendOfZeldaOcarinaOfTime'', by way of TimeTravel. Also [[spoiler:Midna]] in ''[[VideoGame/TheLegendOfZeldaTwilightPrincess Twilight Princess]]'', who spends most of the game in SleepModeSize.

* Subverted with one ''WesternAnimation/DextersLaboratory'' episode where Dexter and Dee Dee plan to become adults in order to watch an R-rated movie. By mistake, Dee Dee knocked over the wires of the aging machine, then re-plug them in the opposite sockets, causing the machine to go sour, [[FountainOfYouth turning everyone into babies]], leaving Dexter and Dee Dee's ages unchanged.

* The slightly obscure manga(?) ''1520'' has an interesting version of the trope. The two main characters, a 15 year old prince and a maid from opposing kingdoms, eat a magical cake by accident that transforms them into ten year old children. Whenever the maid laughs or the prince sheds a tear, that individual will return to his or her proper age, at the cost of de-aging the other down to about five.

* In Manga/MillenniumSnow, Yamimaru (the vampire's bat companion) can take on human form as either a strong young man or an adorable little boy.

* Juugo from ''Manga/{{Naruto}}'' turns into a child when he gives Sasuke some of his flesh to heal him; he turns back into an adult after absorbing absorbing a samurai's corpse.

See also OlderAlterEgo for a child who gets powers in adult form, and SleepModeSize for a powerful adult [[ShapeshifterModeLock Mode Locked]] into a child form. If the character just ages from childhood to adulthood by normal means, it's a PlotRelevantAgeUp or TimeSkip. If a child is forcibly transformed into an adult, it's OvernightAgeUp; the inverse is FountainOfYouth.

* Jewelry Bonney of ''Manga/OnePiece'' does this. She could change her age to any other amount too. And does change the ages of others as well, as a combat technique. She and her crew wear undersized clothes, possibly so they become right-size when they're changed into kids as a disguise.
