* Mordred in ''WesternAnimation/JusticeLeague''. This is bad enough, but infinitely preferable to [[spoiler:ending up with [[AgeWithoutYouth eternal life without eternal youth]] in "[[Recap/JusticeLeagueUnlimitedS1E3KidStuff Kid Stuff]]"]].

* Yugo from ''WesternAnimation/{{Wakfu}}'' still looks like a kid in the Special episodes that take place years after the series proper. He's not exactly thrilled about this since all of his friends have grown up normally. This is taken to a whole new level in season 3, when this disparity starts to bother him when facing the possibility of dating Amalia. When they were both very young (at the start of the show, Yugo was 12 and Amalia was 13), there was nothing wrong, but now in their 20s, Yugo feels like she'd be ridiculed for dating someone who is still in the body of a kid and saddened by the fact that he will live long enough to see her grow old and die, possibly before his body even starts to look like her current age. This is despite the fact she wants to be with him still. In Season 4, [[spoiler:later on, Yugo is forcefully grown into an adult after being temporarely used as a wakfu farm; after the battle against the Necron is over Yugo completely drops all of the previous insecuirities he had in pursuing a relationship with Amalia, they marry right away at the end of the Season]].

* Likewise with [[https://en.wikipedia.org/wiki/Walter_Tetley Walter Tetley]] (the voice of Sherman on ''WesternAnimation/RockyAndBullwinkle''), who either had a condition akin to Kallmann syndrome, or--if costar Bill Scott wasn't just joking--was castrated at his mother's behest so he could keep taking child roles. Unlike Beals, who stood only four and a half feet (137 cm) tall his whole life, Tetley eventually reached a more typical--if still below average--height--of 5'5" (165 cm) after medical treatment.

* ''ComicBook/SevenSoldiers'':
** Another work by Morrison, ''Seven Soldiers: Bulleteer'' explored the concept of eternal youth in the superhero community through Alix Harrower (Bulleteer) discovering her husband had an obsession with a website called "Eternal Superteens" which is essentially a website for eternally young superheroines performing pornographic super feats. He was having an online affair with a woman named Sally Sonic, a 75-year old British woman trapped in a teenage body, who has been [[BreakTheCutie broken beyond repair]] from decades of being used and abused when all she wanted to do was be a hero.
** Given a different twist with Ed Stargard in ''Seven Soldiers: Manhattan Guardian'', formerly part of the kid gang the Newsboys of Nowhere Street under the name Baby Brain. When we see him in the present, it turns out he didn't grow up, but he ''did'' grow old. He looks like an old man with the proportions of a baby, and is hooked up to machines to support him against the frailties of both.

* It's ambiguous in ''Manga/GunslingerGirl'' but {{fanon}} has the eponymous girls stuck at the same age as when they were first turned into cyborgs. Given that the cyborg girls often have a PrecociousCrush on their handler, never growing old enough so that he might comfortably return those feelings is one of the few aspects of being a cyborg that annoy them. In one story, Jose warns another handler that some of the cyborgs can be pretty manipulative, pointing out that his cyborg Henrietta might be an eleven-year-old girl, but she's had years of experience in that.

* Manifestation can physically de-age mutants in the ''Literature/WhateleyUniverse'', although so far most of the cases shown have been induced.
** Eldritch physically is a 31-year-old in a healthy 18-year-old golem, but mentally is a shell-shocked 31-year-old ex-Marine with fragmented memories spanning millenia.

* In the Human in Equestria genre of ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' fanfiction, it is a popular trope for the protagonist to be a male adult human that turns into a young filly after being isekai'd into the show.

* [[spoiler:Porky]] in ''VideoGame/Mother3'' - and is also a [[spoiler:TimeAbyss. However, he is a special case. While he aged physically - by the time you encounter him he's a decrepit old man on life support - mentally he's still the selfish spoiled brat he was in ''VideoGame/EarthBound''.]]

* In ''Series/SoWeird'' episode Rebecca, an old friend of Fiona's mother bumps into her again- not that she would recognize her, as Rebecca looks exactly the same as they did 30 years or so ago as teenagers. Turns out she's not trapped in time, it just takes her 100 years to age a normal person's one year. Go figure.
