extremis powers were pretty badass. comparing them to the chitauri... no contest lol.
maybe feige meant extremis in another sense though? perhaps tony uses it to internalise his armour?
how did pepper shoot killian at the end with no arc reactor powering the arm? in iron man 1 tony had the arc connected to his arm when he was figuring out repulsor blasts, yet by iron man 3 the logic seems to be that the suits have many different power sources. kind of defeats the purpose of a central arc reactor, i dunno.
