Strange #275

Spidey and Nova witness the robbery of a container of rare Antarctic vibranium. They trace the thieves back to a complex run by the Life Foundation and discover that the vibranium is being used as a fail safe for the Tri-Sentinel which the Foundation plans on using for their own protection. Despite Spidey's protests, the Tri-Sentinel is activated and immediately reverts to its original programming, the destruction of nuclear power plants. With the deadly robot on a rampage, Spidey and Nova have a fight on their hands.
