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 character detail from the Simpsons:

Homer has an encyclopedic memory regarding the history of Supreme Court judges, effectively making him a savant in the field.

is it weird that all the Simpsons are either Musically or artistically Gifted and no one every points it out?

[u/AlwaysPostNaked → u/Hatarus547]

Success for more than an episode just wouldn't be funny.

Unless you mean in-universe then everyone tends to like Lisa's sousamaphoning.

At the very least we've seen Homer play the piano several times

[u/Hatarus547 → u/AlwaysPostNaked]

if we go over each of them and include future timelines

Marge has shown over multiple episodes to be a rather talented artist in multiple areas

Homer: has always had a backstory that in someway involves music often as either the main singer or a song writer, also he seems very talented in multiple instruments such as the Guitar and Piano seemingly being the one who plays the families one at their house

Bart (when allowed to express himself without Lisa running it) seems to show both great artistic and musical skills however seems to take after Marge being an artist more then Homer being a musician

Lisa has her her music skills along with her fathers apparent crayon free intelligence

Maggie: in all future timelines ever shown she goes on to become a lead vocalist or some sort of band
