I wish we had more sound motifs in characters like Vader's breathing

What I mean is that there should be more characters with a sound that you can recognize them by. It's a very awesome thing that I don't see much of. The first character that comes to mind is Anakin/Vader with that mechanical breathing. And then there's Spider-Man's Thwip, the sound made by his webs. Other than those two, I cannot think of anyone else with a sound motif and I think it would be really cool to see more of it.
