Action Comics #23.4

In "Full Metal Jacket," John Corben returns from the dead—reanimated with Kryptonite at his core—and quickly proves too dangerous for the military to control. After surviving their attempt to eliminate him, he takes the name Metallo and is drawn into a darker path, joining forces with the Scarecrow’s Secret Society. Written by Sholly Fisch and illustrated by Steve Pugh, with colors by Barbara Ciardo and David Curiel, and a striking cover by Aaron Kuder, this pivotal issue redefines the legacy of a classic villain.
