Two legendary worlds collide… and the universe may never be the same again.
What happens when Teenage Mutant Ninja Turtles crash into the mystical realm of Eternia? You get Masters of the Universe / TMNT: Turtles of Grayskull, one of the most exciting and long awaited crossovers in comic book history.

Dark Horse Comics has finally unleashed this powerhouse mashup, and it’s pure nostalgia-fueled chaos with modern storytelling brilliance.
TMNT Meets Skeletor And Everything Goes Wrong
Krang and Shredder’s secret alliance with Skeletor accidentally opens a portal to Eternia. But this isn’t a friendly visit when Utrom mutagen mixes with demon magic, a terrifying purple poison spreads across the land, threatening to destroy reality itself.

Now Leonardo, Raphael, Donatello, and Michelangelo must join forces with the Masters of the Universe to save Eternia.
But there’s one huge problem…
He-Man is missing in action.
And without the most powerful man in the universe, Eternia stands on the brink of collapse.
A War Across Timelines & Universes
This story goes far beyond a simple crossover.
A mysterious villain steals a powerful Time-Scepter, twisting timelines and creating rips across multiple realities. The Ninja Turtles are thrown into a cosmic chase alongside Renet Tilley, apprentice Timestress and fan-favorite TMNT character.

Together, they must locate He-Man and stop the unseen mastermind before all existence collapses into temporal chaos.
A Dream Creative Team
This epic saga is crafted by two modern comic book legends:
- Writer: Tim Seeley (NY Times Bestselling Author)
- Artist: Freddie E. Williams II (Eisner Award Winner)
Their dynamic storytelling and bold, stylized artwork perfectly blend the action, humor, nostalgia, and emotional weight of both franchises.
