West Coast Avengers (1985) #42 l 193

Its the beginning of what is probably the most important story to ever grace the pages of the West Coast Avengers, Vision Quest!  Big changes start here, changes for both the Vision and the Scarlet Witch, changes which reverberate all the way to modern comics.  And John Byrne returns to the Avengers as both artist and writer!  A new era starts here!
