[Marvel/DC] What are some things characters are known for but were only added in later on to their characterization?

Like Mr.freeze and his wife, or Superman and his flying.

was Barbara Gordon always a genius hacker, was Spider-Man always almost as smart as Reed Richards?

Hank Pym hitting his wife. There was one story like 20 years after he had debuted as a noble heroic character where it happened amidst a mental breakdown and he's unable to ever live that moment down. Now Hank is always slightly mentally unstable and tends to be a bad husband when that's not at all how the character started out.
