The original 1987 Masters of the Universe movie overlooked some of the franchise’s best characters, both in He-Man and Skeletor’s factions.

However,the 2026 movie is already set to break away from the typical structure of most adaptations, asMasters of the Universesees a ten-year old Adam crash-landing on his mother’s homeworld, spending twenty years on Earth and only just becoming reacquainted with his heritage in his thirties. As such, Adam will have to become reacquainted with his royal bloodline.
