Masters of the Universe

In "Masters of the Universe," the malevolent Skeletor harnesses the power of the Cosmic Key, granting him near invincibility as he seizes Castle Grayskull and captures the Sorceress, draining her life-force. He awaits the celestial alignment of Eternia's moon with the Great Eye of the Universe to gain ultimate power. Meanwhile, brave warrior He-Man teams up with Gwildor, the Key's inventor, who possesses another version. During a fierce confrontation, one Key accidentally ends up on Earth, where teenagers Julie and Kevin discover it. Soon, both He-Man and Skeletor's armies descend on Earth, vying for control of this powerful artifact.
