Artemis is the advisor to Minako Aino / Sailor Venus.
In the Pretty Guardian Sailor Moon, Artemis was a plush white cat with green eyes and a golden collar that has a golden crescent moon pendant.
His personality was less critical but more advising. Artemis was at first the only one Minako trusted, though later in series she confided with Rei and eventually became friends with the rest of the girls. Artemis was the one who gave the Sailor Senshi the Sailor Star Tambourines.
