NYPD Captain George Stacy, Gwen's father, informs Peter and his Aunt May that Marko was uncle Ben's true killer; the deceased Dennis Carradine was Marko's accomplice. At his apartment, while Peter sleeps in his Spider-Man suit to wait for Marko, the symbiote assimilates the suit; Peter later awakens at the top of a building, discovering that his costume has changed to black and his powers are enhanced; however, the symbiote brings out his dark side. Peter locates and battles Marko in a subway tunnel. Discovering that water is Marko's weakness, he opens a pipe, releasing water that reduces Marko to mud and washes him away.
