Sapphire Styx

Sapphire Styx made her entrance in the very first issue of Marvel Comics Presents in 1988 — a bold debut alongside Wolverine that placed her right at the heart of one of Marvel's most celebrated anthology launches of the Copper Age. Created by the legendary Chris Claremont and John Buscema, she's a villain with enough staying power to earn a spotlight in the Official Handbook of the Marvel Universe and resurface decades later in Wolverine by Saladin Ahmed, proving she left a genuine mark on Logan's rogues' gallery. Her appearances are select and purposeful rather than sprawling, which gives each one a certain weight — the kind of character serious Wolverine collectors know to watch for.
