There is only one real Superman.'Faster than a speeding bullet! More powerful than a locomotive! Able to leap tall buildings in a single bound! Look, up in the sky! It's a bird! It's a plane! It's Superman! Yes, it's Superman, strange visitor from another planet, who came to Earth with powers and abilities far beyond those of mortal men. Superman, who can change the course of mighty rivers, bend steel in his bare hands, and who fights a never-ending battle for truth and for justice."
Yet, that Superman was a fictional character.
I know the real Superman and His name is Jesus.
