“The Leper from Krypton!”

In "The Leper from Krypton!", Lex Luthor, imprisoned and desperate, unleashes a terrifying new threat: a deadly Kryptonian virus he's engineered, smuggling it to Ventor Caine with the chilling intent of turning Superman into a victim of his own alien biology. Written by Leo Dorfman and brought to life by Ross Andru’s dynamic art and Mike Esposito’s sharp inks, this 1968 classic sees Superman facing a disease as alien as it is deadly. The cover, a striking piece by Neal Adams, captures the grim urgency of the moment.
