I'm pretty sure Killian makes it to the final battle,according to the lego sets
He injects himself with the extremis virus![]()
I'm 100% that's Killian here fighting/flipping Iron Man and it supports the fact that he's infected![]()
We know that the extremis virus enhances the humans physically and makes them able to fight Iron man with their bare hands.
and the Iron Man suit there is the Heartbreaker, which has no mention at all as I mentioned.
