Stålmannen #4/1979

In "Kampen mot kryptoniten!", Stålmannen faces a new threat when an experimental ray transforms him once again, echoing a past incident that turned all Kryptonite on Earth to iron. As he recovers, Lois Lane and Jimmy Olsen cover the aftermath of a space launch, while Perry White and Morgan Edge react to the chaos—only for Stålmannen to confront the villains behind the attack, with Professor Bolden’s research playing a key role in the unfolding crisis.

In "Kryptonitpesten!", Smallville’s townspeople suddenly turn green, and Superboy feels the sickening pull of Kryptonite on his body. Suspecting the Kryptonite Kid is behind the strange transformation, he races into space to confront the culprit. But when he finally faces the Kid, the truth proves far more complicated than he imagined.
