In "Better Dying Through Chemistry," Clark Kent's life takes a bizarre turn when an accident with a chemical vat transforms him into a new, Superman-like being named Chemo. Written and illustrated by John Byrne, this 1987 Action Comics issue pairs Superman with the Metal Men in a tense showdown against a powerful, uncanny doppelgänger. The cover, also by Byrne, captures the moment of transformation with striking clarity.
