And if Iron Man is truly no more, what of Pepper, Rhodey and the Stark Resilient team? With revamped rogues from Iron Man's past on the loose - and the murderous Spymaster finally making his move - all their lives are at stake, and one will be a horrible casualty in Stark's war against Hammer Industries.
