Batman & RobinArtic fear blankets Gotham City as a shimmering figure of destruction—the treacherous Mr. Freeze—unleashes a cold front of crime. Encased in a subzero cryosuit and allied with the sultry and deadly Poison Ivy—a botanical supermenace from the steamy jungles of South America—Mr. Freeze grips the city in a terrifying reign of villainy. But his iciest wrath is reserved for the only crime-fighting force with the ability to stop him—Gotham's guardians, Batman and Robin, who have a secret new partner of their own . . . Batgirl.
