Are you kidding? The only man, and this is man mind you, not meta-human, not mutant, not alien -- regular man -- that could ever beat him was and is Batman. Batman, on every occasion has beaten Superman to within an inch of his life, but for mitigating circumstances, decided against finishing the job.
Clips, if you\'re going to read any new comics other then that atrocious JLA\\Avengers crap, I recommend picking up Superman Red Son, The Ultimates volume 1 (which collects issues 1 - 6), Green Arrow: Quiver, and Y-The Last Man book 1. Every one of those comics will surprise you and make you a very happy comicbook fan. Trust me.
