His performance against bricks seems to vary a lot.
I'm still of the opinion that his physical attributes and even his effectiveness against bricks are criminally underrated, as well.
He's got plenty of insane lifting feats, even though he's scientist first and definitely not your typical "strong guy".
But I digress. Against heralds, his versatility and asborption would certainly prove more useful than sheer physical might (I'm just saying that Tony is not lacking in that department, even though some writers want us to see it that way).
