The death of Roger Sweet at 91 marks the end of a defining chapter in the history of toys and pop culture. As the creator of He-Man, Sweet helped build one of the most iconic franchises of the 1980s, blending action figures, storytelling, and television into a cultural phenomenon.
Sweet was a pioneering toy designer who worked at Mattel during the 1970s and 1980s. He served as the lead designer in the company’s Preliminary Design Department, where he played a crucial role in shaping original intellectual properties at a time when toy companies were heavily reliant on film tie-ins.
He passed away on Tuesday at the age of 91 after battling dementia. His wife Marlene shared details of his final months, which were marked by serious health struggles.
The creation of He-Man was born out of necessity. In 1976, Mattel turned down a deal to produce toys for Star Wars—a decision that later proved costly when the film became a massive success for Kenner Products after the release of Star Wars: Episode IV – A New Hope.
Struggling to create a successful original action figure line, Sweet experimented with a prototype by modifying a Big Jim figure. He glued it into a fighting stance and added clay to give it a muscular build. This prototype eventually evolved into He-Man, which he successfully pitched to then CEO Ray Wagner.

The He-Man action figure officially launched in 1982 and quickly became a hit.
In 1983, Mattel partnered with Filmation to launch the animated series He-Man and the Masters of the Universe. The show was designed to complement the toy line and expand its narrative universe.
Set on the magical planet Eternia, the story followed Prince Adam, who transforms into He-Man using the Sword of Power. The transformation was marked by the iconic line: “By the Power of Grayskull! I have the power,” a phrase that became deeply embedded in pop culture.
The series ran for 130 episodes between 1983 and 1985, cementing He-Man’s status as a global phenomenon.
Sweet’s final months were difficult. His wife revealed that he suffered a serious fall and “couldn’t remember what happened.” Doctors later discovered two brain bleeds, leading to his admission to the ICU and eventually a memory care facility.
The cost of his care exceeded $10,000 per month, prompting his wife to seek public support. Fans responded strongly, with a crowdfunding campaign raising nearly $94,000, far surpassing its initial goal. The Mattel Foundation also contributed financial support.
The He-Man universe continues to evolve decades after its creation. Amazon and MGM, in collaboration with Mattel, are developing a live-action film titled Masters of the Universe, scheduled for release on June 5.
The film features Nicholas Galitzine as He-Man, alongside Camila Mendes as Teela, Jared Leto as Skeletor, Alison Brie as Evil-Lyn, and Idris Elba as Man-At-Arms.
Born in Akron, Ohio, Sweet pursued higher education at Miami University in Oxford, Ohio, before continuing his design studies at the Institute of Design in Chicago. His career at Mattel would ultimately define his legacy.
