Originally posted by carver9the power source for that armor was an enchanted asgardian jewel [which tapped into the same energies as thor's hammer], given to tony by thor himself... so that's a different type of scenario all together.
What about the armor he used to fight king thor?
however, what that does tell us is that tony is capable of building an armor strong enough to not only contain very powerful asgardian magics, but to also pummel, and take a pummeling from, king thor... and he apparently built said armor rather quickly.
