A while back I read about superheroes as icons. Comic book fans, like all fanatics, usually over-estimate how well known the objects of their devotion actually are.
If you have a minute, try to answer four questions about ten supertypes:
1. Do you know the name/can you picture the character?
2. Know the superpowers (flight, super-strength, explosive flatulence)?
3. Know the secret identity (if any)?
4. Know how the character became super?
3. Wonder Woman
5. The Hulk
6. Captain America
10. Plastic Man
If you're remotely interested, I'll put the answers in the following post.
