The She-Ra: Princess of Power toy line was introduced by Mattel in 1984 as a spin-off of the highly successful Masters of the Universe toy line. While Masters of the Universe was primarily marketed to boys, She-Ra was designed to appeal to a young female audience, featuring a female protagonist and a cast of heroic princesses. The line included action figures, vehicles, and playsets set in the magical world of Etheria. The central character was Princess Adora, who could transform into the powerful warrior She-Ra. The toy line was accompanied by a media franchise that included an animated television series and a feature film, helping to establish She-Ra as an iconic character in 1980s pop culture.
