John Byrne transforms the West Coast Avengers! But first, the team must survive showdowns with the Defi ler and the Night Shift - and Mockingbird is haunted by the terrible specter of the Phantom Rider! Then, Byrne takes charge - and the legendary writer/artist immediately leaves his mark on the Whackos with a startling transformation for the Vision! As the team grapples with what's happened to their old friend, Vision's wife the Scarlet Witch descends into darkness - and learns shocking revelations about her children! Amid the chaos, the U. S. Agent muscles his way onto the roster, the bizarre Great Lakes Avengers assemble, and a Golden Age legend blazes his way back from the grave!
