Prince Adam (Revelation)

The son of King Randor and Queen Marlena, Prince Adam is an important character in Masters of the Universe: Revelation, and the human-persona of He-Man.

Battle against Skeletor
When Skeletor attacked Castle Grayskull, Adam was at the Royal Palace with Teela and was the first one to be allerted through a telepathic message from the Sorceress. Adam informs the palace guards and Teela that they must head to Grayskull immediately and protect Eternia. After everyone has left the palace, Adam calls upon the power of Grayskull and transforms himself into He-Man. He is later killed by Skeletor whilst in the form of He-Man, although only few are aware that he and He-Man were one in the same.

After the battle, King Randor and Queen Marlena were behest with the loss of He-Man, but the King becomes outraged when it is revealed that Adam and He-Man were the same person, a fact only shared by Cringer and know by Duncan and Orko. Queen Marlena reveals that she had figured out her son's secret on her own accord. Teela feels equally betrayed by this revelation for having been lied to by Adam and all those close to her.

Adam was awarded a place in Preternia, the Eternian heaven for all the heroic deeds he had performed during his lifetime. There he met many other heroes of Eternia's past, many of whom had carried the Sword of Power before him. However, unlike the others, Adam chose to present himself in his weaker form in the afterlife instead of his guise as the most powerful man in the universe.

Some time passed, and Eternia was slowly but surely dying because all it had lost it's magic. Teela and a new group of allies went in search of the two halves of the Sword of Power to save their planet from destruction. One half of the sword was to be found in Subternia, and the other in Preternia. In fact, when they arrived in the afterlife, they were met by Adam, who carried the sword on his back and offered it to them freely. One of Teela's companions, Roboto, managed to reforge the two halves of the sword in the Central Tower of Preternia and Adam make the decision to leave the afterlife despite the gift that had been given to him there.

Back in the land of the living, Adam was reunited with Duncan and Cringer inside Grayskull, which had taken on it's true form of the Hall of Wisdom. Down in the heart of the hall, Adam once again called upon the power of Grayskull. Magic was restored to the planet, as Castle Grayskull, the Sorceress and Evil-Lyn regained their full power. But just before Adam was to transform into He-Man, he was stabbed in the back by Skeletor, who was also restored, using his Havoc Staff. Mortally wounded, Adam collapsed onto the ground while Skeletor took the Sword of Power from him and invoked the Power of Grayskull for himself.
