Eternia is awakening once more as Masters of the Universe returns to the screen on June 5, 2026, as a bold reimagining of the legendary He-Man franchise, originally inspired by the iconic 1983 animated series He-Man and the Masters of the Universe. As ancient power stirs and old rivalries reignite, heroes and villains alike are drawn into a rising conflict that will decide the future of Eternia.

This guide gathers every known character stepping into the frame, mapping out who stands with He-Man as the next great war for Eternia begins.

Prince Adam, also known as He-Man, is played by Nicholas Galitzine in the upcoming Masters of the Universe live-action film. As the story’s central hero, Adam is a lost prince of Eternia who was separated from his home and the Sword of Power as a child and raised on Earth, unaware of his true heritage. After years in exile, the legendary sword leads him back to a shattered Eternia that has fallen under Skeletor’s tyrannical rule.

Adam must uncover the truth about his past, reunite with allies such as Teela and Man-At-Arms, and embrace his destiny as He-Man.

The film presents Adam as a reluctant but destined hero whose journey takes him from an ordinary life on Earth to the forefront of a cosmic war between good and evil.

In this rebooted storyline, Skeletor, played by Jared Leto, appears as the main villain of Masters of the Universe, reimagined as a tyrannical and power-hungry warlord who has already seized control of Eternia by the time Prince Adam returns. Rather than remaining a distant threat lurking in the shadows, Skeletor is the ruling force of a broken world, with his influence spreading across Eternia and reaching even the legendary Castle Grayskull.

Skeletor is depicted as a powerful dark sorcerer and warrior who draws upon forbidden magic tied to Eternia’s ancient forces, making him one of the few beings capable of rivaling He-Man’s immense power. His abilities, combined with his relentless ambition, establish him as both a physical and ideological opponent for the hero.

Teela is played by Camila Mendes in the upcoming Masters of the Universe live-action film, portraying one of the key heroic warriors of Eternia and a crucial bridge between the kingdom’s royal legacy and the frontline resistance against Skeletor alongside He-Man. As Prince Adam returns to a world already shaped by Skeletor’s dominance, Teela emerges as one of the first major allies to stand against the darkness spreading across Eternia.

The character is portrayed as a symbol of strength, discipline, and leadership rather than relying on traditional magical abilities. Like in most versions of the franchise, Teela is depicted as a peak human combatant whose skills, determination, and battlefield experience make her one of the most capable non-superpowered warriors in Eternia.

In Masters of the Universe, Duncan, better known as Man-At-Arms, is played by Idris Elba and serves as Eternia’s chief military tactician and master weapons engineer. Responsible for designing and maintaining the advanced weaponry and defensive systems that once protected the kingdom, Duncan becomes a vital figure after Eternia falls under Skeletor’s dominance. As the world descends into chaos, he helps organize what remains of the resistance and plays a crucial role in guiding Prince Adam upon his return.

His connection to Adam is largely mentor-like, offering wisdom, leadership, and battlefield experience during the growing conflict. While Man-At-Arms does not possess supernatural powers, he is defined by peak human conditioning, unparalleled combat expertise, and brilliant engineering skills that make him one of the most valuable allies in the fight for Eternia.

The Sorceress of Castle Grayskull, played by Morena Baccarin, appears in the upcoming Masters of the Universe live-action film as the mystical guardian of Eternia’s most sacred and powerful fortress, Castle Grayskull. Serving as the living link between Eternia’s ancient magic and its future, she is entrusted with safeguarding the secrets of Grayskull and protecting the legendary Sword of Power.

As Prince Adam returns to a fractured world threatened by Skeletor’s growing influence, the Sorceress emerges as an important guiding force, helping him understand the greater destiny that awaits him. Deeply connected to the mystical powers of Eternia, she stands as a protector of the balance between light and darkness, making her one of the most influential figures in the kingdom’s fight for survival.

Skeletor’s chief strategist and arcane specialist, Evil-Lyn, is played by Alison Brie in Masters of the Universe. While Skeletor represents raw domination and chaos, Evil-Lyn often serves as the calculating mind behind his empire, using her intelligence and mastery of dark magic to strengthen his grip over Eternia. As one of his most trusted allies, she is deeply connected to the mystical side of his rule, particularly the ancient powers and secrets surrounding Castle Grayskull.

As Prince Adam returns and begins his journey toward becoming He-Man, Evil-Lyn emerges as one of the key forces standing in his way. She sees him not only as a hero but as a direct threat to the order Skeletor has established. Unlike the physically imposing warriors within Skeletor’s ranks, Evil-Lyn’s strength lies in deception and magical control, making her one of the most dangerous opponents in the battle for Eternia.

Beast Man is one of Skeletor’s most feral and intimidating enforcers in the upcoming Masters of the Universe that pulled of the Guinness World Record drone spectacle, serving as a primal extension of his dark army rather than a strategic mind of his own. Although an actor for the character has not been officially confirmed, Beast Man is seen to be brought to life through visual effects to emphasize his savage, beast-like nature in the trailer.

Known for his mystical connection to animals and creatures, he possesses the ability to command beasts across Eternia, making him a dangerous asset within Skeletor’s ranks.

In this reimagined story, Beast Man is positioned as one of the earliest physical threats faced by Prince Adam and the resistance. He embodies the raw, untamed violence of Skeletor’s regime rather than its political or magical sophistication. His presence reinforces the idea that Eternia is ruled not only through sorcery and strategy, but also through fear, brutality, and overwhelming physical force.

Just like Beast Man, Cringer’s voice actor has not been officially announced. However, Cringer is part of the upcoming Masters of the Universe film as the loyal but timid feline companion of Prince Adam, playing a key emotional and symbolic role in He-Man’s journey. Throughout the story, Cringer also provides comic relief, reflecting Adam’s humanity even as he embraces his destiny as He-Man.

In this reimagining of the classic 1983 mythology, Cringer shares a deep bond with Adam long before they are drawn back into the chaos of Eternia. As Adam discovers his true destiny and reconnects with the Sword of Power, Cringer is also swept into the transformation of that world, hinting at his iconic dual nature.

While often fearful and reluctant in his ordinary form, Cringer is destined to become the mighty Battle Cat, one of He-Man’s greatest allies in the fight against Skeletor’s forces.

Trap Jaw is played by Sam C. Wilson in the upcoming Masters of the Universe live-action film, portraying one of Skeletor’s most fearsome cybernetic enforcers and a key member of his inner circle of villains. Functioning as a recurring physical threat during the early stages of the conflict, he frequently clashes with He-Man and the resistance as they regroup against Skeletor’s domination.

His character is built around aggression and adaptability in combat, with his iconic mechanical arm capable of being fitted with different weapons depending on the battle.

In the film, Trap Jaw is depicted as a brutally enhanced warrior who embodies the fusion of dark magic and industrial weaponry that defines Skeletor’s regime. Operating as a frontline executioner and hunter, he is often tasked with tracking down threats to Skeletor’s rule, especially Prince Adam after his return to Eternia.

In Masters of the Universe, Fisto, played by Jóhannes Haukur Jóhannesson, is a powerful heroic warrior of Eternia and one of Man-At-Arms’ closest allies in the resistance against Skeletor’s rule. Traditionally connected to Duncan as his younger brother, Fisto shares a strong bond with the kingdom’s defenders and becomes an important part of the heroic forces rallying around Prince Adam as he returns to Eternia.

His defining trait is his iconic metal fist, which is expected to be adapted into live action as a heavily engineered and weaponized arm that amplifies his power in close-quarters combat. While he does not possess magical abilities like the Sorceress or Skeletor, Fisto’s strength lies in his elite hand-to-hand combat skills.

Combined with his powerful prosthetic arm, he becomes a formidable force on the battlefield, capable of going toe-to-toe with some of the most dangerous warriors in Skeletor’s army.

Based on the confirmed cast listings, James Apps is set to portray Spikor in the upcoming live-action Masters of the Universe. The character is expected to be brought to life through CGI to emphasize his iconic spiked appearance and unnatural durability. Within the story, Spikor functions as a fearsome but relatively straightforward agent of Skeletor’s dominance. 

In this reimagined version of the franchise, Spikor serves as a frontline combatant in the war against Prince Adam and the heroic resistance. His presence adds to the film’s vision of a fractured Eternia populated by hybrid creatures, monstrous warriors, and magically enhanced soldiers battling over the remnants of Castle Grayskull’s power. 

Roboto, voiced by Kristen Wiig in the upcoming Masters of the Universe film, brings a distinct personality to the character’s mechanical nature, often balancing emotionless logic with a growing curiosity about humanity, courage, and heroism. Traditionally depicted as a battle robot with interchangeable weapon arms, Roboto is expected to retain many of those classic traits in the live-action adaptation. 

In this reimagining of the franchise, Roboto is portrayed as a heroic artificial intelligence and a loyal ally of Eternia’s resistance, blending classic science-fiction elements with a more grounded and character-driven interpretation. Created through Man-At-Arms’ advanced engineering, Roboto becomes an important supporting figure as Prince Adam returns to Eternia and begins gathering allies in the fight against Skeletor. 

Goat Man, played by Hafþór Júlíus Björnsson, is one of Skeletor’s most physically imposing enforcers in the upcoming Masters of the Universe. Built to embody pure battlefield intimidation, he serves as a brute-force weapon whose role is to smash defensive lines and spread fear among the scattered remnants of Eternia’s resistance, reinforcing Skeletor’s dominance through sheer strength.

Much like Björnsson himself, Goat Man is defined by his overwhelming physical presence. Brought to life through prosthetics and visual effects that emphasize his monstrous build and animalistic features, the character is expected to function less as a strategist and more as a destructive force of nature unleashed during the film’s biggest battles.

Mekaneck, played by James Wilkinson, appears in Masters of the Universe as one of Eternia’s heroic warriors and a reconnaissance specialist within the resistance against Skeletor’s rule. In this reimagined version, he is integrated into Man-At-Arms’ broader defensive network, serving as a crucial intelligence-gathering asset as Prince Adam returns and the heroes work to rebuild their fractured forces.

Acting as the eyes of the resistance, Mekaneck operates on the edges of major battles, providing vital information that helps guide He-Man and his allies. His role highlights that the war for Eternia is fought not only with swords and sorcery but also with intelligence, awareness, and precise timing.
