Selina Kyle is kidnapped and taken to an offshore island by Dr. Emile Dorian, a genetic engineer with a fondness for cats. He has created a man-cat hybrid named Tygrus, and wishes to provide him with a mate. He injects Selina with a serum which makes her a cat woman in body as well as in name.. Batman learns of this and comes to the island to rescue Selina. He is captured and forced into a deadly game of cat-and-mouse (or cat-and-bat). Tygrus, as the cat-man, hunts Batman through the island's jungles. With Selina's help, Batman manages to convince Tygrus that Dorian, whom Tygrus reveres as his father, is wrong to experiment with peoples' lives. Tygrus attacks Dorian to free Selina and causes an explosion which destroys the laboratory. Batman and Selina escape, and Tygrus rescues Dorian. He asks Batman to take Dorian back to justice and gives Selina the antidote for her mutation, though what he wants most is for her to stay with him. Batman and Selina leave, taking Dorian with them, and Tygrus remains in lonely exile.
