Kayo

Stepping into the wild, toy-aisle-meets-comics energy of 1989, Kayo made their debut in He-Man #2, brought to life by the distinctive hand of Carol Lay during the Copper Age's anything-goes creative boom. Published under Mattel's banner, this character inhabits a corner of the He-Man universe populated by heavy hitters — sharing pages with Prince Adam, He-Man himself, the sinister Skeletor, Captain Hydron, and the unsettling Optikk. With only a handful of appearances in the catalog, Kayo is a genuine rarity, the kind of deep-cut discovery that makes longtime fans of Masters of the Universe lore sit up and take notice.
