He-Man is a superhero and the main protagonist of the sword and planet Masters of the Universe franchise, which includes a toy line, several animated television series, comic books and a feature film. He-Man is characterized by his superhuman strength and in most variations, is the alter ego of Prince Adam. He-Man and his friends attempt to defend the secrets of Castle Grayskull, the planet Eternia, and the rest of the universe from the evil forces of his archenemy Skeletor.

The character was created by designer Roger Sweet, who intentionally created the character in such a way for him to be abstract and generic enough to be applied into any context and genre; Sweet also chose the name "He-Man" for being generic. Presenting three different versions of the figure to Mattel—including a soldier and a spaceman—the barbarian version of the character was chosen and developed into the character's current form.

The television series He-Man and the Masters of the Universe mushroomed the selling of Mattel's toys and was a hit success in the 1980s, gaining 9 million viewers in its first year in the USA alone and being broadcast to at least 37 countries.

He-Man has achieved gay icon status and amassed an LGBT following due to his perceived homosexuality. According to various insiders and employees, Mattel is aware of He-Man's gay icon status and following, and his perception as a gay man something to which the company is sympathetic.
