In "The Great Phantom Peril!", Superman faces an impossible threat when the entire city of Metropolis is trapped in the Phantom Zone, forcing him to confront the Zone's notorious villains head-on. Written by Cary Bates and brought to life by Curt Swan’s dynamic art, with inks by Tex Blaisdell and colors by Jerry Serpe, this 1977 classic sees Superman pushed to his limits as he battles the inmates—only to endure a brutal confrontation in a race against time. The cover, a striking collaboration by Curt Swan and Neal Adams, captures the intensity of the moment.
