About me: Skeletor is the main antagonist of the Masters of the Universe , and is the most evil being and most dangerous threat on Eternia. His only goal is power, and to that end he will not rest until he possesses the secrets of Castle Grayskull, whereby he could become master of the universe. This places him in direct conflict with the only man powerful enough to stop him, He-Man.
Skeletor was formerly a warlord known as Keldor who trained under Hordak. He gathered a small band of warriors to attack the Hall of Wisdom. They encountered resistance from Captain Randor and his officers; Keldor fought Randor personally, wielding two swords with astounding proficiency, but when Randor disarmed him, Keldor threw a vial of acid at him, which backfired with drastic results. Randor deflected it with his shield, and the acid splashed on Keldor's face.
Kronis called the retreat, and Evil-Lyn took Keldor to Hordak's sanctuary, where Keldor summoned Hordak to save his life. Keldor agreed to pay whatever price Hordak wished for his life, and Hordak transformed him, stripping the damaged tissues from his skull and dubbing him Skeletor; Keldor's head had been completely stripped of soft tissues, leaving only a floating skull. When Keldor saw his new appearance, he laughed maniacally, the incident perhaps shattering whatever sanity he had left.
