Like I said, Supermans powers are not really original. look at the other fictional characters before comic books came out. look at the olympian gods and the egyption gods. they can fly and they have superhuman strength. i dont know why they're picking on marvel for copying superman. Superman is not really original. i can even go further back before they had olympian gods /egyption gods and that is the christian holy bible. they had Celestial beings that are called heavenly angels , guardian angel , archangels and seraphim. they had superhuman strength and super speed and thats not all the powers they have. heavenly beings are also shape shifters with magical powers and they also have supreme science to back them up. in otherwords heavenly beings are more powerful than the justice league and superman put together. if i had to put money on a fight my money would be on heavenly angels. the justice league would be defeated and destroyed by the heavenly angels Vanguard of Heaven, guardians of the Universe.
well its true... He was strong enough to be an immediate problem-solver so they opted to make him a looney so that when the Skrulls were about to launch their Secret Invasion they simply accused him of been responsible for that (because of the Void the dark aspect of his self/power) so unable to determine if that was true or not he fled the planet in self-imposed agony leaving the rest of the heroes to deal with the situation !!
