Castle Grayskull - King Grayskull

King Grayskull

In the 2002 remake of He-Man, it is revealed that Castle Grayskull was once home to King Grayskull, an ancestor of Prince Adam, who died defending his kingdom and Eternia as a whole from Hordak.

Upon his death, King Grayskull transferred his power into his sword that now forms the basis of He-Man's power. His wife Veena became the first Sorceress, and his advisers became the Council of Elders. He also had an enormous green lion as a mount, bearing the same armor as Battle Cat, and is presumably where Battle Cat gains his powers.
