Why was “Masters of the Universe” canceled?
“Masters of the Universe” wasn’t really canceled. It ended when Mattel decided to get Filmation to animate their new toy, She-Ra: Princess of Power. She-Ra went into production just as He-Man was ending. The series may have continued for a third season, but She-Ra was given main priority. As a result, He-Man went from being the star to the guest star. She-Ra lasted 93 episodes compared to He-Man’s successful 130 episodes, She-Ra was actually cancelled by Mattel due to poor sales. Filmation stopped producing the show after the poor run of 28 new episodes.
