"Machines have inherited the Earth, with Ultron as their All- Father. Mankind's only hope will be a time-torn team in the tradition of Avengers Forever. An early Hulk, Jim Rhodes as Iron Man and a Hela-cursed battle-armor Thor are plucked from the past. The unlikely duo of Vision and Black Widow are drawn from our present. And from the near and not-so-near future, the new Thor and an even newer Captain America, with her own heroic legacy to live up to. Who cries 'Assemble' to this unique group? The one and only Dr. Doom. Caught between Ultron and Doom, can the Avengers find a way to save forever?"--Amazon.com.
