This issue is a cross-over with Daredevil (vol. 1) #84.

Panel 3 on page 11 is an interesting image. It is intended to succinctly capture the battle between some of Earth's heroes and Mister Kline, the android from 30 centuries in the future. As noted by the footnote in this image, this conflict was chronicled in Daredevil #s 77-84 and Iron Man #s 41-45.

The picture is symbolic. Standing on the palm of each of Mister Kline's hands are key characters from these stories. On Kline's left hand stand (from left to right) Marianne Rodgers, Iron Man and Soulfather/Mikas. Standing on Kline's right hand are: Dardevil, Black Widow, Scorpion, The Owl, and Mister Hyde.
