Within the heavyweights, Superman is by far the weakest. Flash, can kill them all in 1s. Green Lantern can create everything you imagine, even without imagination fighting hard, it's the superman level. WW according to the latest numbers, is stronger than Superman and without weaknesses. Superman is average (compared to heavyweights), but he also has weaknesses, kryptonite, red sun, telepathy (he has been controlled more than any other), magic, and surely more. Superman, the greatest and most powerful hero in the world, is a lie.
