The Shitennou (四天王; meaning "Four Heavenly Kings") were the four loyal and faithfully devoted generals and bodyguards of Prince Endymion. When they were all possessed by Metalia's vast negative energy, they became evil and served Queen Beryl and the Dark Kingdom. The members were Jadeite, Nephrite, Zoisite, and Kunzite. Each of them were named after a different stone.
