In the broadest part of his plans, the High Evolutionary plots to construct a bomb that will genetically alter all life on Earth. He sends the Gatherers and a superhuman team known as the Sensors to Wakanda to obtain vibranium necessary for completion of the bomb. Unbeknownst to the Evolutionary, one of the scientists he has forced into his service is Bill Foster, who surreptitiously alerts the Black Panther to the situation. The Panther and the West Coast Avengers defend Wakanda but are unable to prevent the theft of the vibranium. Coincidentally, estranged Avengers Moon Knight, Tigra, and Mockingbird happen upon the High Evolutionary's citadel in the Savage Land and rescue Foster, who recovers his Giant-Man powers. With the security of his base compromised, he relocates his base to the floor of the Pacific Ocean.
