Iron Man, Vol. 1

An object of unknown origin appears in front of Doom in his chambers, and he takes it for study. It is incredibly old and of mystical origin, but little else is known about it. He soon learns that a similar object appeared before Iron Man. When Tony refuses to sell it, he tries to take it by force. The two objects couple together, and when the two armored warriors get close to them, they are both engulfed in some sort of black light.
