in the movies, which changed it from the original, in the comic books Asgardians are gods, also doing characters worse? are you talking about wasp, which was the exposition character, which they didn't give all that much screen time or dialogue lines, which considering she was an exposition character they did rather well, or Hulk which they made somewhat more intelligent because the dumb hulk from the original cartoon because in a team scenario would be annoying and uninteresting, or maybe you meant Hawkeye which they manage to make him into an actually badass character despite being just a guy with a bow, or how they changed captain america into a character that wasn't boring and dull
