He-Man creator Roger Sweet dead at 91 -- the Mattel toy designer who bulked up a Big Jim figure into the musclebound barbarian that launched the entire Masters of the Universe empire back in 1982 just passed peacefully at a care facility after a long battle with dementia. Yeah the guy who got a bonus check and zero royalties while his creation printed billions for the company had fans scrambling a GoFundMe to cover his final months.
