Avatar - Ideas

Ok now that I've started second life and seen different examples of avatars i'm starting to think of mine.Looking at different peoples ideas I feel that when I create my avatar I would like to show a hidden meaning behind my avatar and show it. For example like hiding behind a mask,like some people what people see in a person might not be the real them, they're hiding behind an identity.

Superheros are a good example of this so maybe I could be a superhero?
