10. Green Lantern

Since the name in itself is Green Lantern, you realize that this is a superhero that contains something which is symbolizing the color green, and you are not way off the mark. The power or rather the superpower of the Green Lantern is basically a ring that controls the superhero, ensuring that the person can do justice, and also take care of the world that he or she is in. The Green Lantern has been responsible for taking care of the earth, and the superpower basically lies within the ring, which has extraordinary capabilities to transform into anything as desired by the person controlling the ring. However, you need to remember that it is the ring that chooses a person worthy of it, not the other way around.
