Skeletor, a demonic dictator, awakens in Eternia, the first planet of creation. With dark legions at his command, he's on the march, hell-bent on seizing Eternia's kingdoms, and its ultimate treasure, Castle Grayskull, an old fortress of mystery thought to house the universe's greatest power. It's up to Yuri Lowenthal's He-Man and his brave band of rookie heroes to stop Skeletor and restore order. Both sides are equipped with enchanted Power Weapons that transform them into Masters of the Universe's Primal Powers. It's Master vs. Dark Master, He-Man vs. Skeletor in a battle for control of Eternia, Castle Grayskull, and our collective fate. Who will be crowned Master of the Universe at the end?
