History Main / DualAgeModes

* Signal in the manga/anime ''Twin Signal'' has two forms: An adult {{Bishonen}} form, and a childlike SuperDeformed mode with an insane [[TrademarkFavoriteFood love for chocolate.]]

* 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 their proper age, at the cost of de-aging the other down to about five.

* [[spoiler: Mithos/Yggdrasil]] from the game ''TalesOfSymphonia''.

* [[spoiler:Cereza/Bayonetta]] in ''{{Bayonetta}}''.

* In ''AhMyGoddess'', Belldandy mentions that the three goddesses are each a representation of time. Belldandy represents the Present, so when she uses too much of her power, she just needs to sleep. However, when her sisters use too much power, Urd, representing the Past, reverts into a child form, while Skuld, representing the Future, grows up into a teenage form.

* Tom Hanks' character in ''[[Big]]''.

* Dave Bowman in ''[[TwoThousandTen 2010]]''

* [[{{Naruto}} Juugo]] turns into a child when he gives Sasuke some of his flesh to heal him; he turns back into an adult after absorbing one of the samurais.

* The titular ''Game/SpaceAce'' in the laserdisc video game is turned into a child as a result of the BigBad Borf's "Infanto Ray". During certain parts of the game, the player has the chance to "energize" Ace and turn him back to his adult form for a short time; adult Ace sequences tended to be more about fighting villains while child Ace spent most of his time trying to avoid or escape enemy attack.

* Link in ''TheLegendOfZeldaOcarinaOfTime'', by way of TimeTravel. Also [[spoiler:Midna]] in ''TwilightPrincess'', who spends most of the game in SleepModeSize.

* Vivio and Einhart of ''MagicalGirlLyricalNanoha'' [=ViVid=] both have their normal, elementary school forms, and their teenage forms they use in combat.

* ''SpacePirateMito'' is an alien that [[OlderThanTheyLook looks like a third grader,]] [[ReallySevenHundredYearsOld despite being over ten thousand years old]], but has a [[PowerArmor mail suit]] that she uses for combat that looks like an adult human. She has similar suits for [[MobileSuitHuman just masquerading as a human adult]], and a good deal of the conflict in the first half of the series comes from trying to get her half-human son to accept her actual, childlike, form, when for most of his life he's only seen her in mail-suit form.

* Jewelry Bonney of 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.

See also OlderAlterEgo for a child who gets powers in adult form, and SleepModeSize for a powerful adult [[ModeLock 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.

* Similar to [[IAmNotShazam "Captain Marvel"]], MalibuComics' ''{{Prime}}''. He also had a DistaffCounterpart called "Elven."

* Miss Hinako in ''RanmaOneHalf'' has the default form of a girl of about eleven years, and turns into a [[HelloNurse 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 PressurePoints.

There are a lot of characters who can [[VoluntaryShapeshifting change their shape]]. Some have fewer options than others, and a lot are limited to only [[SwissArmyHero a handful of forms]]. One common set includes an aged pair: the same general appearance, in a childlike and an adolescent or adult form. Often, one will be the natural form for the character, with the other being invoked by some [[InvoluntaryShapeshifting external trigger]]. But most of the time, the child form will be used only to make the character look more innocuous or relatable.
