Roger Sweet was one of the original designers who helped to develop the popular Masters of the Universe toy line for Mattel. He developed the exaggerated physique, the action stance, and the swivel-action waist of the characters. Roger Sweet also originated the name "He-Man". The character was intended to be generic so that it be used in all sorts of ways, from sci-fi to fantasy to real-world situations. Roger Sweet continued to work on the toy line throughout its original span, contributing to the line by originating many of the characters, vehicles and playsets.
