How a failed Conan the Barbarian toy deal birthed the Masters of the Universe
In short: After passing on Star Wars, Mattel sought a new hero for boys. When a planned Conan the Barbarian collaboration collapsed, the company pivoted to create its own muscular icon. The result was He-Man, a global phenomenon that briefly outsold Barbie and redefined the landscape of children's television and toy marketing.
In 1976, Mattel famously declined to produce toys for Star Wars, a decision that left the company eager to capture the boys' action figure market. By 1982, Mattel had developed its own line, Masters of the Universe. The project was not without controversy; the creators of the film Conan the Barbarian sued Mattel in 1984, alleging that He-Man was merely a copy of their character. The court dismissed the claim, ruling that the concept of a muscular hero—a 'hunk'—could not be copyrighted.
The character's design was a collaborative, if contested, effort. Creative lead Roger Sweet developed three prototypes, while artist Mark Taylor provided sketches that informed the final look. To avoid limiting marketing potential, Sweet chose the generic name He-Man. The toy line was launched alongside mini comics that provided rich backstories, encouraging children to collect the entire set. These comics, some produced by DC, introduced Prince Adam as He-Man's secret alter ego, a narrative choice that deepened the franchise's lore.
The transition to television was equally strategic. Mattel collaborated with the studio Filmation to produce an animated series, which debuted in 1983. By airing the show through syndication rather than a traditional network, Mattel bypassed early rejections and reached a massive audience. At its peak in the mid-1980s, the toy line generated $400 million in annual sales, briefly surpassing Barbie. The series itself, spanning 130 episodes, became a cultural touchstone, with its protagonist’s transformation cry—'By the power of Grayskull, I have the power!'—becoming one of the most recognizable catchphrases in animation history.
The franchise's influence extended beyond mere sales. The success of the show, which was the first syndicated series based on a toy, fundamentally altered the market for children's programming. While the original run concluded in the mid-1980s, the brand has seen numerous reboots and adaptations, proving the enduring appeal of the battle between He-Man and the villainous Skeletor for the secrets of Castle Grayskull.
