Roger Sweet, the legendary toy designer who gave the world the muscular hero He-Man and other characters from the cult "Masters of the Universe" franchise, has died at the age of 91. Mattel announced his death on Tuesday but did not disclose a cause. Sweet lived in Lake Stevens, Washington, about 50–55 kilometers (30–35 miles) northeast of downtown Seattle. The quiet suburb is known for its namesake lake, scenic views of the Cascade Mountains, and family-friendly atmosphere, making it popular with people who work in the tech or aerospace sectors. The choice of region was not accidental: Washington state and the Seattle area attract people who value privacy, proximity to nature, and a quieter pace of life compared with the bustle of Southern California. For Sweet, the move may have offered a respite from the entertainment industry and a chance to find inspiration in the quiet life of the Pacific Northwest.
The story of He-Man’s creation began with a missed opportunity. Several months before the release of Star Wars in 1977, George Lucas offered Mattel the toy license for the forthcoming blockbuster, but the company declined. The deal went to rival Kenner, which turned it into a goldmine. To make amends, Mattel tasked Sweet with coming up with a counterpunch.
"Market research showed that kids liked three things: barbarian fantasy, futuristic military themes like Star Wars, and modern military themes like G.I. Joe," Sweet said in a 2019 interview. He took a 24-centimeter figure, gave it a dynamic pose, broadened the shoulders, and added a massive amount of clay. Thus was born "the most powerful man in the Universe" — nearly naked, sculpted muscles, wielding an axe and shield.
Released in 1982, He-Man became the centerpiece of an entire Masters of the Universe line, which included the skull-like villain Skeletor and the hero’s sister She-Ra, also created by Sweet. The toy was an instant hit and spawned the animated series He-Man and the Masters of the Universe (1983–1985), whose battle cry "I have the power!" echoed across American schoolyards.
In its first three years Mattel sold more than 125 million toys in the line. It was a powerful breakthrough in an overcrowded boys’ toy market dominated by Transformers and Voltron. However, by the late 1980s the franchise’s popularity waned, especially after the 1987 live-action movie starring Dolph Lundgren as He-Man flopped at the box office.
After leaving Mattel in 1991, Sweet largely led a reclusive life, appearing occasionally at conventions. In his 2005 memoir Master of the Universe he accused company executives of trying to take credit for his work and lamented that he did not receive fair compensation: "For three years in a row my bonus was only 50% of my salary."
In recent years the franchise has enjoyed a resurgence. In 2021 Netflix released the rebooted series Masters of the Universe: Revelation, and Sweet’s toys were inducted into the National Toy Hall of Fame. In June 2025 Amazon and Mattel will release a new feature film starring Nicholas Hoult, Jared Leto, and Idris Elba.
Despite disagreements with his employers, Sweet retained his love for his creation until the end of his life. When he married Marlin, the top of the wedding cake was decorated with He-Man and She-Ra figures, and the inscription read: "He-Man takes Marlin as his wife." "I always wanted to be He-Man, but I couldn't," the designer admitted. "And I knew that almost every guy in the world wanted the same thing." Those who want to explore Sweet’s legacy further should visit the Museum of Pop Culture (MoPOP) in downtown Seattle. Although it does not have a permanent exhibit dedicated solely to toys, it regularly hosts exhibitions on video games, animation, and science fiction where artifacts from the He-Man universe may appear. Additionally, the Seattle region, including Redmond with Nintendo of America’s offices, is an important hub for the entertainment and design industries, underscoring Sweet’s connection to the area.
