Superman #162 2000

Superman #162, published by DC in July 1963, presents "The Amazing Story of Superman-Red and Superman-Blue!" In this classic imaginary tale, Superman attempts to boost his intellect, inadvertently splitting into two distinct beings. Superman-Red marries Lois Lane and settles on a new Krypton, while Superman-Blue marries Lana Lang and remains on Earth. This issue is notable for the first appearance of these dual Supermen and is a beloved non-continuity story that ties up many loose ends in Superman's life.
