Color: White
Sex: Male
Favorite Scout: Minako/Sailor Venus
Artemis is Minako's Guardian Cat, much the same as Luna is to Usagi. He was alive during the Silver Millenium, and was an advisor to Neo Queen Serenity. When Neo Queen Serenity sent everyone into the future, she gave Artemis and Luna the task of finding all the scouts once they were on earth. While Luna was working in Tokyo, Artemis searched in France. It was there that he found Minako, the first scout. Minako fought evil in France as Sailor V until Luna found all the other scouts. Once that happened, Artemis brought Minako to Tokyo to join all the other scouts to form the Sailor Senshi.
Artemis has always had a crush on Luna, and later on in the series, they finally get together. They soon learn about Diana, their daughter from the future, who would be the Guardian cat of ChibiUsa. (Don't ask how a white cat and a black cat mate and make a purplish-pink cat! ^_^)
Artemis is also control central, the place that Luna would report to about their findings. Eventually she found out that it was Artemis because Artemis messed something up and Luna heard his voice.
