King Hiss

King Hiss is the ruler of the Snake Men, an ancient and treacherous faction of serpent warriors on Eternia. Beneath his humanoid disguise writhes a mass of hissing snakes, making him one of He-Man's most dangerous foes.

Few villains in the Masters of the Universe mythology carry quite the reptilian menace of King Hiss, who slithered onto the scene in 1985 — deep in the Bronze Age — courtesy of creators Steven Grant and Bruce Timm. Ruling his own corner of Eternia's rich tapestry, he keeps genuinely dangerous company, sharing pages with He-Man, Prince Adam, Skeletor, Rattlor, and The Sorceress across titles like King of the Snake Men and the Masters of the Universe Annual. His publishing life stretched a remarkable 26 years from 1985 to 2011, a testament to how deeply this Snake Men sovereign burrowed into the franchise's lore. For collectors drawn to Eternia's wilder, more sinister edges, King Hiss is an essential — and delightfully cold-blooded — piece of the puzzle.
