[Zen]

Not only is he the first ever, you have to admire a guy who despite having so many powers, lets face it, he could be an unstoppable force morals aside. Decides to be selfless, decides to fight out of love for the people of earth, he has no childhood trauma, no vengeance plot thickening inside of him, the guy simply does what he does because he can. Sure he might not be the greatest character, batman for example is more interesting (though i hate frank miller's batman :P) , but he is DEFINITELLY the greatest superhero.
