Nicholas Galitzine as Prince Adam and He-Man
Nicholas Galitzine plays the film’s central hero in both identities. Prince Adam has spent years away from Eternia, but the Sword of Power pulls him back to a kingdom controlled by Skeletor. His task is not simply to transform into He-Man. He must accept the responsibility attached to that power and reconnect with the people he left behind.
Camila Mendes as Teela
Camila Mendes plays Teela, one of Adam’s closest allies after he returns home. Teela stands beside Adam in the fight against Skeletor and remains one of his closest allies as he returns to Eternia.
Idris Elba as Duncan and Man-At-Arms
Idris Elba plays Duncan, better known as Man-At-Arms. He is one of Adam’s closest allies and a key member of the team fighting to reclaim Eternia.
Jared Leto as Skeletor
Jared Leto takes on Skeletor, the ruler who has left Eternia shattered during Adam’s absence. This version leans into the villain’s theatrical, fantasy-heavy presence. Skeletor is the main force Adam, Teela and Duncan must confront if they are to reclaim the kingdom.
Alison Brie as Evil-Lyn
Alison Brie plays Evil-Lyn, one of the franchise’s most recognisable antagonists and an important figure on Skeletor’s side. The casting adds a performer with strong comic timing to a villainous role inside the movie’s knowingly playful fantasy world.
The royal family and Eternia’s allies
James Purefoy appears as King Randor, while Charlotte Riley plays Queen Marlena. Morena Baccarin is the Sorceress, a major figure in Eternia’s magical mythology. Jóhannes Haukur Jóhannesson plays Malcolm, also known as Fisto, expanding the group of recognisable Masters around He-Man.
Kristen Wiig voices Roboto
Kristen Wiig provides the voice of Roboto. The casting matches the film’s willingness to bring humour into its fantasy adventure, while keeping the character connected to the technology and spectacle of Eternia.
