Writer: David Michelinie
Artist: Mark Bagley

Spider-Man and Nova discover that Carlton Drake has rebuilt the Tri-Sentinel. Drake tries to send it after Spider-Man, but the Tri-Sentinel overrides the controls and returns to Loki’s original directive of destruction. Spider-Man and Nova fight it. Drake put antarctic vibranium in a sealed container in its brain as a fail safe (i.e. when the container is opened, the Tri-Sentinel’s brain will melt). Spider-Man enters the head, but gets trapped in a force field bubble. Nova gets trapped in some coils it shoots.
