Overview
Masters of the Universe (sometimes referred to as the He-Man or She-Ra series) is a sword and planet-themed media franchise created by Mattel. The main premise revolves around the conflict between He-Man (the alter ego of Prince Adam) and Skeletor on the planet Eternia, with a vast lineup of supporting characters in a hybrid setting of medieval sword and sorcery, and sci-fi technology. A follow-up series, She-Ra: Princess of Power revolves around He-Man's sister She-Ra and her rebellion against The Horde on the planet Etheria. Since its initial launch, the franchise has spawned a variety of products, including multiple lines of action figures, six animated television series, several comic series, video games, books and magazines, a daily newspaper comic strip, and two feature films (one animated, one live action).
Series overview and main characters
He-Man and the accompanying Masters of the Universe franchise would make their debut in 1982 with Mattel's release of the original "Masters of the Universe" 5.5-inch action-figure toy line. Masters of the Universe, often abbreviated as MOTU, would begin its mythos through the minicomics that accompanied the toys throughout the 1980s. These initial mini comics were soon followed by several children's books and issues of DC Comics. However, the Masters of the Universe franchise would become best known through Filmation's groundbreaking He-Man and the Masters of the Universe animated series. Debuting in the fall of 1983, the Filmation series ran 130 episodes over two seasons until November 1985.
Since its inception, Masters of the Universe has usually placed its focus on the two primary characters, the blond muscular He-Man, "the most powerful man in the Universe," and his nemesis, the evil skull-faced, blue-skinned sorcerer Skeletor and their many moral-themed encounters on the planet Eternia. Set in a hybrid world of sword and sorcery and technological sci-fi, He-Man battles with Skeletor to prevent him from conquering Eternia and discovering the secrets of Castle Grayskull—a mysterious ancient fortress with a skull-shaped facade, containing great power and magic. As with many toy franchises that have been transferred to several different media, there are a number of story differences between the various versions of Masters of the Universe.
