Spider-Man [Peter Parker]; The Prowler [Hobie Brown]; J. Jonah Jameson; Robbie Robertson; Gwen Stacy; Mindy (Hobie's Girlfriend, reference only)
Spidey and the Prowler fight. The Prowler gets away using a gas bomb, then plans another robbery to make himself (Hobie) a hero when the loot is recovered. Peter anticipates the move and gets there during the robbery. This time the Prowler's gas has no effect and Peter unmasks him to find a well-intentioned kid like himself. Spidey lets him go.
