I watched the clip and i guess comic Superman is much stronger then the movies or cartoons that i have seen. I still find it funny that Superman gets beaten up by Doomsday if he has this kind of strength. By just rotating his body to face Doomsday he should create a force strong enough to disintegrate Doomsday instantly.

The problem here is what Animeniax brings up. DB was around for 10(?) years or so before it was ended. Superman is called the worlds oldest Superhero since he was brought to life in the 30's. Thats 80 years for them to just continue to upgrade his powers. Powers that he doesn't seem to earn in any way. They did mention that he trained that fighting style of his, but his actual powers just grow by them selfs.
