Agreed on Thor's serious amount of badassery. There is an arguement that that the Silver Surfer is more powerful than Thor, but for most of Surfer's incarnations he was notoriously hard to piss off. But Thor, (unless you were somone like the Hulk who could take a lot a lot of damage,) you just REALLY did not want to get on the wrong side of that guy..
AS for MUA II, I'm unable to get my copy until next Friday, but I've heard that the voice acting for Thor is really bad. Much worse than what was in the first MUA. (And that wasn't quite perfect to begin with..)So I seriously hope his dialogue is a lot of fun, to make up for the bad voice casting..
