Masters of the Universe / Teenage Mutant Ninja Turtles: Turtles of Grayskull

When the Power of Grayskull collides with the Heroes in a Half-Shell, the universe gets a lot weirder—and a lot more dangerous. This 2024–2025 Dark Horse miniseries, written by Tim Seeley and drawn by Freddie E. Williams II, merges the sword-and-sorcery realm of Eternia with the sewers of New York City, forcing the Teenage Mutant Ninja Turtles and the Masters of the Universe to team up against a threat that blurs the lines between magic and mutation. Over four issues, it delivers the kind of crossover that feels both inevitable and delightfully unexpected, honoring the distinct tones of each franchise while finding common ground in high-stakes action and character-driven chaos.
