The Return of Kraven

Spider-Man and the Black Cat attempt to confront Kraven. After the latter eludes the two heroes, there are various reports of attacks. Debra Whitman decides to investigate and she, Black Cat, Flash Thompson, and Dr. Connors 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.
