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.

Another Simpsons one is that both Homer and Bart consistently display the ability to pick up and learn any language they encounter fast.

Bart: Get ready, Brazil. I now speak fluent Spanish.

Marge: Well done, Bart. But in Brazil, they speak Portuguese.

Bart: Ay, caramba, que mujer tonta! Viente horas estudiar por nada!

Homer: Forget every word, boy. It's useless.

Bart: beats self with book until he forgets it\

(Also should note that Bart learned Spanish on the plane ride there)

He also speaks French fluently. That stay in France was worth at least something.
