"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. The initial group of characters and premise were created by Filmation, while the characters introduced later were designed by Mattel. Mattel provided financial backing for the show, as well as an accompanying toyline. The series premiered in 1985 and was cancelled in 1986, after 2 seasons and 93 episodes.
On March 22, 1985, Filmation released an animated movie based on the series titled, He-Man and She-Ra: The Secret of the Sword. The film is composed of five episodes from the She-Ra television series: "Into Etheria", "Beast Island", "She-Ra Unchained", "Reunions" and "Battle For Bright Moon".
