History YoungerThanTheyLook / WesternAnimation

** DJ, Leshawna and Trent from the original cast

* In ''WesternAnimation/{{Castlevania}}'' due to accelerated aging ([[{{Dhampir}} being half Vampire]]), Alucard is likely in his early 20s despite looking and sounding much, much older.

* In ''WesternAnimation/AmericanDad'', Stan mistaken a 23-year-old waitress for a fat old man.

** Oskar is established to be 38, yet he looks much older by his being balding and wearing clothing more akin to a senior citizen, including a collarless shirt and a pocket watch.

* Wolfgang in ''WesternAnimation/HeyArnold'' is a fifth-grader, yet is tall and muscular like a senior high school jock. Matter of fact, the rest of the fifth-graders look more like high school students than fifth-graders. While one could argue that it's just an exaggerated perspective the fourth-graders have on kids roughly over a year older than them, [[OlderThanTheyLook it doesn't explain why Harold, a 13-year-old, is smaller than the fifth-graders as well]] (and was even shown getting called a "fruit cup" and a "sissy fat boy" by Wolfgang in one episode too).

** The titular heroine herself is only 17 at the start of the series, but is so [[BoobsOfSteel physically mature]] you could easily mistake her for being in her 20s.

* The titular characters in the ''WesternAnimation/BeavisAndButthead'' episodes where they are middle aged, they’re 45 but look like they’re pushing 60, because of how poorly they take care of themselves.

* ''WesternAnimation/TheOwlHouse'': Eda looks to be in her 50s or 60s, and sounds like it too, but her older appearance is a side effect of a curse she received as a young teenager. Her sister Lilith is actually ''older'' than her even though she looks much younger, with WordOfGod later confirming that they're both in their 40s.

** Strongly [[ImpliedTrope implied]] with Iroh. While neither he nor Ozai have their exact ages stated, Ozai look to be in his late thirties or early forties, while Iroh looks about 20 years older. There's no indication that Azulon had Ozai a lot later, particularly considering Iroh was the rightful heir to the throne.
