BLACK PANTHER/NAMOR: DOOMED #3

Emerging from Avengers: Armageddon and Captain America, this issue forces three rulers who cannot stand one another into an alliance. Black Panther, Namor and Doom are targeted by a greater enemy for the single attribute they share, and defeating the Kingkiller requires each of them to subordinate his own agenda, which none of them has ever managed before. Whether this is a working alliance or the beginning of the end for the Marvel Universe's monarchs is the question at hand.
