The "Masters of the Universe" were first introduced as a toy series by Mattel in 1982. The figures and accessories quickly became a huge success. The brand was later developed further as an animated series and in the form of comics, which still have a large fan base today.

The Masters of the Universe are a group of characters from the action figure series and animated series of the same name from the 1980s. The main character is He-Man, a muscular hero with a magical sword power who defends the planet Eternia from the evil forces of Skeletor and his army. Masters of the Universe also includes a number of other characters such as Teela, Man-At-Arms, Orko, Ram-Man, Beast Man and Mer-Man. Each character has their own unique abilities and traits that are used in the fight against the evil forces of Skeletor.

Mattel has been releasing old classic action figures in modernized editions since 2008. The Masters of the Universe have experienced a renaissance in recent years, with the release of new toys, comics, and a remake of the animated series on Netflix.
