...Anyway, wasn't Thanos beaten by half dead Nebula when he had the IG?
A plot device is a plot device, and has nothing to do with the power that one can put out or take (usually).
I don't see how your reasoning means anything, and besides, the greatest minds on Earth and lots of help beat Onslaught. Cosmic doesn't mean everything, and it certainly doesn't mean he was weak just because.
Im saying though if the Surfer went all out hed be one helluva threat as well. Most of the heroes who opposed Onslaught werent serious threats. I know he was powerful but he was nowhere near Tyrant or Odin level. Thanos has stood up to both characters prefinal upgrade.
