Dr. Doom and the Red Skull together again! And what is the fate of the original Captain America, Steve Rogers -- and how can he help save himself from the accidental trap he's found himself in? All this and more -- as the Avengers and the FF battle insane odds to save Marvel's Fallen Son!
Plus, ‘Siege’ tie-in!! The Siege brings Ragnarok to Asgard! The Shining City of Thor and his brothers in arms faces destruction on the greatest scale it’s ever suffered, at the hands of Norman Osborn and his Dark Avengers. But the Norse heroes have bigger problems, when Thor fights Thor! The evil Thor clone has come to kill the God of Thunder and take his place. Even if Asgard survives the Siege…will Thor survive Ragnarok?!!
Also, Tony and Pepper, trapped in Tunguska by Madame Masque, play the ultimate game of truth or dare at the business end of a very loaded gun. Is Tony strong enough and smart enough to escape the clutches of a woman who burns to see him suffer? And halfway around the world, the Black Widow joins Maria Hill, and they summon the most good of all the good guys... Captain America! But is he willing to come to Tony's aid?
