I can't take it anymore.
If your talking about a stable Superman, (Superman Returns version) Super Saiyan Goku kills him.
Comics are weird, there are great comics, but a Super Heroes' power various too much to say any feat is accurate, some comic books contradict others. In DC, Laws, rules=Nothing. But in the Shonen Jump Manga, and a Superman movie, powers aren't contradicted, they stay the same. What I mean by a stable Superman is a Superman that's powers aren't contradicted and virtually abides by the laws of physics, (When Routh grabs a plane by its wing, the wing comes off)
So yeah, Super Saiyan Goku FTW.
