Writer: David Michelinie

A man just built a machine that he wants to use to study Spider-Man’s powers. Spider-Man agrees, but it starts taking away his powers and he jumps out of the beam. At an airport he fights and defeats The Femme Fatales. Including Mindblast, Whiplash, Bloodlust, and Knockout. He then decides he doesn’t want MJ or Aunt May to ever lose him, so he goes back to the scientist and says he wants to stand in the machine until it takes away his powers forever.
