Superman-Red and Superman-Blue

Sensational events ensue when the malfunctioning of a complex “brain-evolution machine” in the Fortress of Solitude accidentally transforms Superman into two identical Supermen, one clad in a blue costume and the other in red one, each endowed with the super-intellectual 100 times as powerful as the original.

Armed with their vastly increased super-powers, the two benevolent Superman, referred to as Superman-Blue and Superman-Red, set out to fulfill: together the two Supermen re-create the exploded planet Krypton to its last topographical detail; alter the atomic structure of Kryptonite, rendering harmless to Kryptonians; enlarge the bottle city of Kandor; provide a water-world home in outer space for Lori Lemaris and the other Atlantean mer-people; and bring about the total eradication of crime, warfare, and evil by flooding the Earth with a potent “anti-evil ray” of their own invention.

Now with these and other great tasks completed, Superman-Blue and Superman-Red marry Lana Lang and Lois Lane respectively and settle down to lives of wedded bliss (S No. 162: “The Amazing Story of Superman-Red and Superman-Blue!").
