PRECRISIS Superman and the Superman who STRUGGLES TO POWERLESS RICH nikkaS LIKE BATMAN AND LEX LUTHOR are two different people
The Superman that "struggles with Lex and Bruce" would still have the edge over the Goku that almost got KOed with a rock:
For anybody to compare these bullshyt comic heroes to anyone else is complete nonsense. These comics are so fukking broken, the damn heroes can't even be touched by anybody else in their universe. That's why you would use the universally accepted version, which would get raped by Goku.
Comic characters have much more source material than almost any other fictional character around, while Goku's anime and manga that have been static for decades, Superman is getting constant new stories every single month and considering he existed LONG before Goku was even a thought, it makes sense that he is going to have much more feats, and probably more impressive feats, than almost anyone.
You can't complain that comic characters are "fukking broken" and too powerful but still weaker than Goku, that's a contradiction. Let's keep it real, Goku is one of the most powerful characters in fiction, but he is still under Superman who is ALSO one of the most powerful characters in fiction.
