Iron Man: Extremis #5 by Adi Granov and Warren Ellis

2005 Marvel Comics – First Printing in Fine/Very Fine condition – this one has a slight spine roll.

Maya watches as Tony’s body scabs over and begins repairing itself. Eventually, it cracks open and Tony emerges, better than ever. He reveals that he made some modifications to Extremis by creating his undersheath inside his body and storing it in his bones. With it, he can control the armor directly from his brain and proves it by armoring up with a thought. Using his new ability to communicate with satellites, Stark takes off after Mallen.
