Master Menace

Master Menace is a brilliant, scheming supervillain native to the Squadron Supreme's alternate Earth (Earth-S), where he serves as a persistent thorn in the side of that world's heroes, relying on intellect and technology rather than superhuman power.

A cunning villain who slithered into Marvel's alternate-reality tapestry when Mark Gruenwald and Paul Ryan introduced him in Squadron Supreme #6 in 1986, Master Menace is one of the Copper Age's more intriguing antagonists — a schemer operating in the shadow of powerhouses like Hyperion and Nighthawk. His footprint spans a respectable 24 years across titles like Squadron Supreme and Exiles, suggesting a staying power that belies his modest appearance count. If you're drawn to the rich world-building of Marvel's parallel Earths, Master Menace is exactly the kind of deep-cut character who rewards the curious collector willing to dig in.
