Tony arrives just as Obadiah is about to execute Pepper. The two ironclad warriors begin a huge, brawling battle that spills into the streets near Stark Industries. Tony flies into the upper atmosphere, drawing Obadiah along with him. Obadiah struggles but before long begins to freeze up -- his suit has the same icing problem that Tony's Mark II had. Obadiah begins to fall back to Earth, leaving Tony hovering above. The older arc reactor begins to lose power rapidly and Tony falls back to Earth, landing on top of his factory, running on auxiliary backup power.
