Chapter IV: The Return of Kraven

Spider-Man teams with the Black Cat in an attempt to confront Kraven the Hunter. After Kraven eludes the two heroes, there are various reports of attacks. Debra Whitman decides to investigate and she, Black Cat, Flash Thompson, and Dr. Curt Connors hunt for clues, and succeed in identifying the DNA as female. It turns out that Dr. Crawford had been given the same serum that drove Kraven crazy, in order to heal her from a fatal disease; unfortunately, it mutated her into a feral form. Luckily, Dr. Connors creates a serum that restores Dr. Crawford’s mind, allowing her to live as Kraven’s equal.
