Prince Adam of Eternia, son of King Randor and Queen Marlena (an earthling), who ruled the Kingdom of Eternia on the planet of the same name. The Sorceress of Castle Grayskull endowed Prince Adam with the power to transform into He-Man, which Adam did by raising his Power Sword and proclaiming, "By the power of Grayskull..." Once the transformation was complete, he would continue, "...I have the power!". Prince Adam's pet was a cowardly green tiger named Cringer. When Adam became He-Man, he transformed Cringer into a brave armored green tiger named Battle Cat by pointing his sword at him – an ability Adam discovered accidentally during one of his transformations into He-Man. Cringer, naturally, cowered in fear at seeing what Adam had become; while reassuring him that nothing had really changed, Adam pointed the sword of power at Cringer, which sent a bolt of energy toward the tiger and transformed him. Battle Cat served as He-Man's steed and fierce fighting companion ever since. He-Man possessed one-half of the Power Sword; Skeletor had the second half, and used it as his main weapon. When joined, the two halves of the Power Sword will provide the key to Castle Grayskull (this is why the two figures' swords could combine into one, when the action figures were initially released). In one early illustrated story, He-Man and Skeletor united their two Power Sword halves to form the true Power Sword, defeating a common enemy
