Thor VS Superman Forum
One punch wouldn't be enough, but continuous punches would certainly knock him out, I didn't say he would get blitzed under normal circumstances though, you brought up the city busting attack which requires Thor to briefly charge, if he does that then yes he will get blitzed.
We haven't seen Thor use AOE attacks against 1 opponent or a group of people comparable to Kryptonian's who will be constantly rushing him, and I still believe they have better combat speed so they will get more strikes in.
Zod can fly? He flew against Superman and they even went into space and back again.
Thor threw his hammer at Iron Man in the Avengers and hit him with it again at the end of their fight. Whedon even said that Thor was 'seeing red' by the end of their fight meaning he wasn't holding back that much. It's clear that the Kryptonian's outclass Iron Man in every stat so they should be able to take more hammer shots.
