The Stark-Roxxon War (Iron Man, Volume 1)

With his company restored, Tony Stark's first order of business is getting Stark Unlimited back out of the weapons game. But a multinational company doesn't just stop selling weapons overnight, and the board is more concerned with profit margins than super-hero ethics. Now they've made a deal with the devil: Stark Unlimited is for sale, and the highest bidder represents the combined might of Tony's two biggest competitors, Roxxon and A.I.M.! But they're ready for the old Tony Stark. This one? He's a lot angrier than he used to be. New armor, old enemies and unbelievable twists abound in this fresh take on a fury-powered Iron Man!
