In the storyline of the franchise, it is the target of numerous attacks by Skeletor, Hordak and the Snake Men, all of whom believe that the secrets inside will allow them to conquer Eternia and the entire universe, and become the titular Masters of the Universe. Castle Grayskull plays a key role in the transformations of both He-Man and his twin sister She-Ra in the 1983-1985 He-Man and the Masters of the Universe series, and in its 1985-1987 spinoff/sister series She-Ra: Princess of Power.
Gary S. Cross, professor of modern history at Pennsylvania State University, writes that Castle Grayskull is emblematic of the making of a boy-man culture beginning in the 1980s.
