Peter Parker, the Spectacular Spider-Man #089 (1984)
Writer: Bill Mantlo
Artist: Al Milgrom
The Black Cat goes on a search for super powers so she can assist Spider-Man instead of hindering him. The Kingpin agrees to help her. He just enhances her cat abilities using Stillwell’s devices. She acquires cat-like swiftness and whoever tries to harm her is dealt bad luck. Because she’s the Black Cat. Kingpin wants her to destroy Spider-Man, but doesn’t ask her to. I assume her bad luck is supposed to befall him. This issue ends the same as 251 of Amazing Spider-Man. Leading into Secret Wars.
