He-Man Creator Roger Sweet Dies at 91 After Battle With Dementia

Roger Sweet, the toy designer credited with creating the He-Man character and helping launch one of the most beloved franchises of the 1980s, has died at age 91. Sweet's wife, Marlene, confirmed to TMZ that he passed away peacefully on Tuesday morning, April 28, at the care facility where he had been living while battling dementia.

A Health Decline That Touched His Fans

Sweet's condition had come to public attention just months before his death. In February 2026, Marlene revealed that her husband had suffered a frightening fall while walking alone and was unable to remember what had happened. Medical evaluation revealed two brain bleeds, and Sweet was hospitalized in the ICU before being transitioned to a memory care facility — a level of care that came with a monthly price tag exceeding $10,000.

To help cover those costs, Marlene launched a GoFundMe campaign that quickly exceeded expectations. Fans who had grown up watching He-Man on television in the early 1980s responded with remarkable generosity, pushing the fundraiser well past its original $50,000 goal and ultimately raising nearly $94,000. The Mattel Foundation contributed $5,000 to the effort, a meaningful gesture from the company whose history Sweet had helped shape.

The Creation of He-Man

Sweet worked at Mattel during the 1970s and 1980s, and he is widely credited with developing the He-Man concept after pitching multiple versions of a muscular, sword-wielding action figure hero to the company. The character became the centerpiece of "He-Man and the Masters of the Universe," an animated television series that debuted in 1983 and became a cultural phenomenon.

At its peak, the franchise was one of the most commercially successful toy lines in history. He-Man became a defining figure for an entire generation of children — his catchphrase, "I have the power!," lodged itself in popular memory in a way that few fictional characters manage. Sweet's role in conceiving the character has been the subject of some ongoing discussion in toy history circles, given the collaborative nature of development at large companies like Mattel, but his central contribution has been widely acknowledged.

A Legacy Still in Motion

Sweet's death comes as a new live-action "Masters of the Universe" film from Amazon MGM Studios and Mattel is scheduled for release this summer — a measure of how durable and commercially relevant the franchise he helped create remains nearly five decades later. Marlene told TMZ she had been attempting to reach the producers of the film in hopes that they would dedicate it to Roger.

The timing gives Sweet's passing a particular weight. He created something that outlasted the era in which it was made, survived the shift away from hand-drawn animation, and is now returning to theaters as a major studio production. That kind of cultural endurance is rare in any creative field, let alone in the competitive and trend-driven world of children's toys.

Remembered by a Generation

The outpouring of support for Sweet's GoFundMe campaign — which came from fans who have long since grown into adults — said something about the lasting impression his work made. He-Man was not a brand they consumed passively; for many, it was a formative part of childhood. The donations, the messages, and the response from the broader pop culture community reflected the degree to which Sweet's creation had stayed with people long after the cartoons ended and the toys were packed away.

Roger Sweet is survived by his wife, Marlene. He was 91.
