My fantasy response to that question would be to grab the asker by the collar, get into his face, and growl, “I’m Batman. Tell all your friends about me.”

Instead, I’m Paper.

You Are Paper

Crafty and creative, you are able to adapt freely to almost any situation.
People tend to underestimate you, unless they’ve truly seen what you are capable of.Deep down, you’re always scheming and thinking up new plans.

Your mind is constantly active.  You are quite capable of anything you dream of. You can always figure out a way to get what you want. You can wrap a rock person up in your sheet of trickery.

A scissor person can sneak up and cut you to pieces.

When you fight: No one can anticipate your next move If someone makes you mad: You’ll attack them mercilessly when they’re unprepared.

Are You Rock, Paper, or Scissors?
