Amazing Spider-Man (1963 1st Series) #352
"Death Walk!" Part 2 of 2. Guest-starring Nova. Script by David Michelinie. Pencils by Mark Bagley. Inks by Sam de la Rosa. Cover by Mark Bagley and Randy Emberlin.
While Nova battles the Tri-Sentinel from the outside, Spider-Man makes his way inside the deadly robot; but still finds himself hampered by its defensive measures! When the Life Foundation shows up to erase an incriminating computer disk (that Nova has taken), the Tri-Sentinel gets caught in their magnetic blast! Which stops the robot long enough for Spidey to release the Antarctic vibranium in the control center and cause the Tri-Sentinel to explode!
