Superpowers are things that you will never have, things that people could use to save people's lives, things that people could use to ruin the universe....things that could make a difference....
Basically put, superpowers are powers that every superhero (except that bat guy) and supervillain has. They include X-Ray Vision (useful when you're looking at hot chicks), heat vision (useful when you want to make yourself a cup of coffee), flying (you can make airplane noises while flying if you wish), and super strength.
Unfortunately, many of these superpowers come with a superhero weakness, for instance, if you wanted to get rid of Superman, crush him under seven tons of kryptonite or something...
For some reason though, most superheroes have never mastered the arts of reality warping, which is a good thing as it would make comics pretty boring!
Some people use their powers responsibly (like Spider-Man), while others use it to do despicable things (like Doctor Octopus).
So if you fall into nuclear waste or something like that, use your superpowers responsibly!
