If you could have one super power which would it be? Just one, no cheating.
Would you fly like Superman? And where would you go?
The power of invisibility is a good one; if you had this power how would you utilize it?
Super strength is a common trait in most heroes.
How about ESP? Think about what you could accomplish if you could read people’s minds.
Another great one would be super genius. Would you solve the world’s economic problems with it, or find the cure to cancer? Would you figure out how the human race could give up its dependence on fossil fuels?
Remember though, power can corrupt and effect one's perspective. When you have these special abilities there is always the moral angle to consider. Selfish and prideful feelings could sway ones decency to the point an honorable citizen could deviate and cross the line. The personal perception between hero and villain blurs when egotism and selfish needs creep into the picture.
