Template:InfoboxCharacter King Endymion was the name taken by Mamoru Chiba during the reign of Neo-Queen Serenity in the distant future. He did not appear for very long in either the anime or manga, so there is very little known about him. He was always seen wearing a lavender tuxedo and a white mask.
In the manga and musicals, he could still use the attack Tuxedo La Smoking Bomber, and possessed the Golden Crystal.
During the second season of the anime, King Endymion sent nightmares to his past self, which caused Mamoru to break up with (and act cold towards) Usagi in order to prevent her from being killed as was depicted in his dreams. This was, however, not the King's intent; he wanted Mamoru and Usagi's bond to be stronger in order to help them survive the onslaught of the Black Moon Clan and Wiseman.
