Emmett Vale

A scientist who discovers the rocket that brought Kal-El to Earth, Emmett Vale becomes convinced Superman poses an alien threat to humanity. He captures criminal John Corben and surgically transforms him into the Kryptonite-powered cyborg Metallo to serve as his weapon against the Man of Steel.

A shadowy figure woven into the very fabric of Superman's post-Crisis reinvention, Emmett Vale made his mark in John Byrne's landmark The Man of Steel #1 in 1986 — one of the most consequential debut issues in DC history. Though his catalog footprint is modest, the company he keeps is anything but: Vale's pages are shared with Superman himself, Lois Lane, and the fearsome Metallo and John Corben, placing him squarely at the heart of the Man of Steel's world. Across nearly four decades, he surfaces in the flagship titles Action Comics and Superman, a quiet testament to his staying power in the mythology Byrne rebuilt from the ground up. For collectors chasing the DNA of the modern Superman era, Vale is one of those intriguing threads hiding in plain sight.
