He-Man and the Masters of the Universe had done extremely well for Mattel. The one problem; the show was targeted towards the male species! Working closely with Filmation once again, Mattel created She-Ra, the twin-sister of He-Man. The action figure for girls was launched and initially everything went well.

Mattel once again asked Filmation to create sixty-five episodes of She-Ra Princess of Power. As before they wanted a simple cartoon that advertised their action figures and nothing more. As production on the He-Man and the Masters of the Universe series was halfway through season two, Filmation began animating She-Ra Princess of Power. The problem they faced was that according to the toy line She-Ra's greatest threat came from "jealous beauty" Catra. The Evil Horde from the Masters of the Universe action figure line had yet to be featured in the He-Man animated series, so a decision was made to have the Evil Horde as She-Ra's villains!

Filmation and Mattel planned something big to launch She-Ra Princess of Power, so they combined the first five episodes that had been animated, known collectively as "The Sword of She-Ra," and pieced them together renaming the film "The Secret of The Sword." It may not have broke box office records, but it was a good start for the She-Ra series.

This time around the writers were even stronger and more cohesive than they had been for the start of the He-Man and the Masters of the Universe series. Larry DiTillio, Bob Forward, J. Michael Straczynski and Robert Lamb shaped the world of Etheria.

Unlike the He-Man series, She-Ra had less limited animation due to a slightly larger budget, more consistent writing and most notably, superb visual direction from the ex-storyboard staff who were now directors, Tom Tataranowicz the man to watch!

Unfortunately even though the series was very good it was not as profitable as the He-Man series had been. Mattel wanted one last push so they gave the green light for a second season of twenty-eight episodes to be produced. These episodes had some of the best animation and directing that Filmation had ever seen. Sadly sales plummeted and the worlds of Eternia and Etheria were no more.

She-Ra Princess of Power had a total of one ninety-three animated episodes and one theatrically released movie.
