Cyberex

A menacing presence from the earliest days of Marvel's cosmic frontier, Cyberex burst onto the scene in 1968's Captain Marvel #8 — a Silver Age debut crafted by Arnold Drake and Don Heck right at the heart of one of Marvel's most ambitious new mythologies. Sharing those charged early pages with Mar-Vell, Carol Danvers, Colonel Yon-Rogg, and Medic Una, Cyberex is woven into the very foundation of a corner of the Marvel universe that would grow into something legendary. With appearances catalogued across an impressive four-decade span, this character's footprint stretches well beyond a single era, and Essential Captain Marvel ensures those classic stories remain accessible to curious collectors. Rare in count but rich in pedigree, Cyberex is exactly the kind of deep-cut Silver Age find that rewards fans who love digging into where it all began.
