Become the Master of the Universe when you build Eternia's mythical fortress and reveal the secrets hiding within Castle Grayskull!
You'll have the power when you build your own Castle Grayskull. Based on the Masters of the Universe: Classics version, every detail of this castle has been faithfully recreated, right down to the working elevator, turrets and throne room with trap door – the Jawbridge is even activated by the Power Sword! Build this massive fortress using more than 3500 pieces, then battle for Eternia with the 6 included micro action figures: He-Man, Skeletor, Man-At-Arms, Beast Man, the Goddess and the Sorceress. Castle Grayskull was built to protect an unknown source of power – and now you can build it too!
