Roger Sweet obit

R.I.P. Roger Sweet, creator of He-Man

After suffering from dementia, Roger Sweet, who created and named He-Man while working at Mattel in the '70s, has died at the age of 91. 

 He was not on the list.

Roger Sweet has died. Best known as the creator of He-Man, Sweet was a preliminary designer at Mattel during the development of the Masters Of The Universe line. Before his death, his wife, Marlene, announced that he was moving to an assisted living facility due to dementia. She confirmed her husband’s death to TMZ. He was 91.

An Ohio native who graduated from Chicago’s Institute of Design in 1972, Sweet moved out to California to work at Mattel after college. While there, the company turned down a contract to produce the toys for Star Wars because of the $750,000 up-front licensing fee. The company had its Preliminary Design Department, where Sweet worked, designing some male action figure ideas to make up for the missed opportunity. Amid his fellow artists submitting ideas like “Robin and the Space Hoods,” Sweet submitted an idea called “Monster Factory,” though he admitted in a 2005 interview, “it was actually a barbarian fantasy.” As for the name, Sweet brainstormed as many as 50 names, including Mighty Man, Megaton Man, Strong Man, and Big Man. When he got to He-Man, a “bell rang in my head[…]it’s just one in a million.” Though he considered himself a “flyspeck on the elephant’s rear end in relation to all the work and talent that other people put into this line,” he supplied “the seed from which the Masters tree grew.”

“I originated and named He-Man,” he said in 2019. “I originated the three prototype models that brought He-Man and Masters of the Universe into existence.”

The “Masters Of The Universe” toy line hit shelves in 1982, with He-Man and Skeletor leading the charge. It was followed by a DC Comics series and, most popular of all, an animated television series, created by Filmation, in 1983. But He-Man And The Masters Of The Universe‘s popularity declined sharply around the time the Dolph Lundgren-led movie hit theaters, with revenue dropping from $400 million to $7 million. Sweet diagnosed the issue as Mattel overselling the product to stores and the declining popularity of the TV show.

Sweet married Marlene in the ’80s, and even had the designers from He-Man build a plaster wedding cake, with “HE-MAN TAKES MARLENE FOR HIS BRIDE” written on the cake and a He-Man figure holding his bride as a topper. He stopped working at Mattel after more than 15 years of service. Since then, he attended numerous Comic-Con events and, according to Marlene, “always loved talking about HE-MAN and MASTERS with all the fans.”

Though the character continued to be remembered fondly and rebooted frequently, Sweet, like many creators, never saw much of the money from its success. In February 2026, shortly after the trailer for a $200 million Amazon-backed reboot was released, Sweet’s wife launched a GoFundMe to cover her husband’s dementia treatments. Unable to continue living at home, the 91-year-old was moved to a care facility, which cost over $10,000 a month and wasn’t covered by Medicare. TMZ reports that Mattel donated $5,000 to the cause, while the fundraiser went on to raise more than $93,000, shattering its $50,000 goal.

“I am having no luck in my goal to reach the producers of the forthcoming He-Man and Masters movie,” she wrote in a March 29 update. “It would be so appropriate if they would dedicate this movie to Roger as the creator of He-Man, and also to Mark Taylor, who created Skeletor.”

Roger Sweet was born in 1935, and grew up in Akron, Ohio. He graduated from Miami University in Oxford, Ohio, and the Institute of Design at the Illinois Institute of Technology. Sweet served as a lead designer at Mattel throughout much of the 1970s and 1980s and worked extensively on the Masters of the Universe toy line. Before working for Mattel, Sweet held design positions with Walter Dorwin Teague Associates, an industrial design firm, and other design companies. He worked on the accounts of such companies as Boeing, Rubbermaid, Hoover, and Procter & Gamble, and on such products as the interior of the Boeing 747 jumbo jet airliner, and the Downy and Scope packages.

In 1976, Mattel's CEO Ray Wagner declined a request to produce a toyline of action figures based on the characters from the George Lucas film Star Wars. Amid the commercial success of the film trilogy and its related merchandise, Mattel attempted to launch several unsuccessful toylines, none of which captured the public's imagination or made a significant dent in the toy market. These included Kid Gallant, a medieval knight; Robin and the Space Hoods, a sci-fi figure; and the daredevil Kenny Dewitt (pronounced "Can He Do It)?"

Sweet was a lead designer for Mattel's Preliminary Design Department throughout much of the 1970s and 1980s
