It’s official! Mattel announced via press release what we all knew was coming: the Masters of the Universe x Teenage Mutant Ninja Turtles crossover line, called Turtles of Grayskull. The line will be available starting in January 2024 and celebrates the 40th anniversary of the Teenage Mutant Ninja Turtles. The Turtles will don Eternian-style battle gear and Skeletor in Turtle-inspired armor.

From Mattel:

The partnership between Masters of the Universe and Teenage Mutant Ninja Turtles allows fans to create new storytelling moments with the Turtles of Grayskull line which outfits characters including Leonardo and Raphael, Donatello, and Michelangelo with Eternian-style battle gear, and He-Man from Masters of the Universe will battle his Mutagen Mutation while Skeletor will don Turtle-inspired Armor. Merging these worlds, which are both narratively jam-packed with creative possibility, unlocks even more storytelling opportunities for fans across both brands.

“Bringing the Teenage Mutant Ninja Turtles into Masters of the Universe is a dream come true for many action figure fans. This is an unprecedented moment to collide fan-favorite properties – never been done before in the rich history of both brands,” said PJ Lewis, VP and Global Head of Action Figures at Mattel. “This collaboration represents two great brands that will ignite the imaginations of fans young and old alike.”

Although we just have a poster of characters that accompanied the press release, an image of Leonardo as a Turtles of Grayskull surfaced from at Toy Fair earlier this month.
