When Chibiusa ran away from home and came to stay with Usagi and Mamoru in the twentieth century, King Endymion followed her to Kaguya Island in the guise of Space Knight.
As Space Knight, he protected his daughter and the past versions of his wife and friends while they were unable to transform. After he helped Loof Merrow in a battle against the minions of Coatl, she fell in love with him and later returned the favor by saving him in turn. In the final battle against Dark Plasman, Space Knight revealed his identity and eventually returned to the 30th Century with Chibiusa.
