Writer: David Michelinie
Artist: Erik Larsen
Magneto decides to go after Spider-Man himself. Flash is training to become a boxer. Spider-Man decides to test his powers out and goes to an automobile wrecking yard by the bay. He blasts a stack of cars with an immense energy blast. He lifts a multi-ton barge as if it didn’t weigh anything. Magneto arrives and fights him. He attacks using a crane. Spider-Man unintentionally turns the crane into glass. Magneto throws some cars at Spidey, but he makes a giant bat out of webbing and knocks them out to the bay. Using his much more advanced hearing and sight, he discovers one of the cars hit a boat. He can’t web out there to save them, but discovers he can fly and carries the boat to safety.
