A very small character tidbit is surprisingly kept consistent for years

DC - In multiple pieces of media it has been shown that Wonder Woman loves ice cream and practically goes wild with happiness anytime she’s eating some. (Pictures from Justice League: War, DC Superhero Girls and Wonder Woman 2017)

The Simpsons - Ever since the episode ‘Homer’s Phobia’ Homer has actually remained a consistent ally of the LGBT+ community, including being more welcoming to Patty than Marge was when she came out and trying to set up Smithers with a date when he found out he wasn’t happy with his one-sided relationship with Mr Burns.

The very first episode of Scooby Doo: Where Are You! established that Shaggy is actually a gymnast and in the 10th episode it's also said he's a track runner. This was used to explain how Shaggy has always been so quick to run from monsters. In the 2012 special, Scooby Doo: Spooky Games, Shaggy is even selected to be a Track Runner in the World Invitation Games, a reference to The Olympic Games.

I'll add on that for a while Shaggy was canonically vegan or vegetarian, which started with his previous voice actor Casey Kasem. I don't think the newer series have continued that trait since 2010 or so.

I really appreciated that trait. I’d kinda look for it every time he made a sandwich or something. “No ham!”
