Biography
Endymion resided in The Golden Kingdom in Elysion with his four guardians, the Shitennou. He fell in love with Princess Serenity and met her as often as possible, but the two lovers are found out and separated by Kunzite and Sailor Venus.

He died defending the Moon Kingdom from Queen Beryl's forces, now led by his brainwashed former guardians. Princess Serenity committed suicide in despair.

After Tuxedo Mask is mortally wounded, the Silver Crystal is released from Sailor Moon's body, and the couple are revealed as reincarnations of Serenity and Endymion. He is kidnapped by the Dark Kingdom shortly after, but not before a piece of the Silver Crystal is placed inside of him by Serenity in order to try and save him. He becomes possessed by Metaria, and he tries to take the Silver Crystal from Sailor Moon. Sailor Moon uses the Legendary Sword against him, injuring him, and releases the piece of Silver Crystal, as well as releasing him from Meteria's control.
