Artemis is Minako's white guardian cat, as well as her advisor.
Nomenclature & Etymology
Artemis was the Greek goddess of the moon and hunting, the twin sister of Apollo and the daughter of Zeus and Leto. She was known as Diana to the Romans.
Artemis is a white short-haired cat with green eyes with pale pink ears and a gold crescent moon on his forehead.
Just like Luna, Artemis was a trusted advisor and confidant to the Queen of the Moon Kingdom. He did his very best to protect the princess and heiress to the throne of Silver Millennium at all costs. When the Moon was invaded by the evil force, Queen Metalia, and her brainwashed Earthling minions, Artemis stayed by Queen Serenity's side as she used the vast energy and power of the Silver Crystal to seal away the enemy for one milenia.
