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.
She-Ra is a cartoon debuting in 1985. Also, a series of toys under her name were produced by Mattell. She is the alter ego of Princess Adora and the twin sister of Prince Adam/He-Man. She-Ra was intended to appeal to young girls in the same way that He-Man appealed to young boys.
She-Ra is introduced in the animated movie The Secret of the Sward as Force Captain Adora, a member of the Evil Horde that rules the planet Etheria. Princess Adora discovers that she is the long lost twin sister of Prince Adam of Eternia, having been kidnapped as a baby by the Horde's leader Hordak. She is granted the Sword of Protection, which parallels He-Man's Sword of Power, gaining the power to transform into She-Ra, her secret identity.
