Belasco

A sorcerer of immense dark power, Belasco is an ancient human who bargained with Elder Gods for near-immortality, gaining mastery of black magic and dominion over Limbo, the demon-filled dimension he rules as its tyrannical overlord.

Belasco slithered out of the Bronze Age in 1982, conjured by Chris Claremont and Brent Anderson in the pages of Uncanny X-Men #160 — a collector-significant debut that immediately announced him as a force to be reckoned with in Marvel's darker corners. This sorcerous villain has haunted some of Marvel's most beloved series across four decades, from Magik (Illyana and Storm Limited Series) and New Mutants to more recent appearances in Mary Jane & Black Cat, proving his sinister staying power. His shadowy presence has put him in the company of icons like Wolverine, Storm, and Colossus, and his reach across 44 years of publication speaks to a character whose menace never quite goes out of style. For fans who love their Marvel mythology steeped in the supernatural, Belasco is exactly the kind of deep-cut villain whose appearances are always worth hunting down.
