She-Ra: Princess of Power is an American animated television series produced in 1985 by Filmation. A spin-off of Filmation's He-Man and the Masters of the Universe series, She-Ra was aimed primarily at a young female audience to counterbalance He-Man's popularity with young males. Unlike the He-Man cartoon, which was based on the Masters of the Universe toy line by Mattel, the creation of She-Ra was a collaboration between Filmation and Mattel.
