I really did not know where to place him as far as power goes. There were some good feats but as far as I saw the biggest feat was wrecking Iron man, and as far as I am aware he should have done that anyway, upgrade or no.
But really volstagg took a big blast...I was not convinced. I think he could have been in the parifarary of the blast that destroyed Soldier feild(sorry bears fans) as he was not the target of that blast.
thor on the other hand was the direct target of a same level blast and he was still standing. Then he got hit......OK should he be so powerful that he never gets hit? yes the reporter said Thor was down but that is a cliffhanger. garantee he will be on his feet next issue and will do some damage.
Levitating Asgard and creating that big crevasse impressed me. Plus there's no doubt he's bulletproof nowadays.
The Iron Man fight, though I agree with the outcome, seems kinda weird, as Tony's suit IIRC is not metal, it's cloth with forcefields, nor is it weak to electromagnetic pulses.
