Who is Artemis in Sailor Moon?

Artemis is a white, male cat who first appears in the “Sailor Moon” manga in Act 7, “Mamoru Chiba, Tuxedo Mask,” and in the original anime, he debuts in episode 33, “Enter Venus, the Last Sailor Guardian.” He is the guardian and advisor to Minako Aino, also known as Sailor Venus, and was sent by Queen Serenity from the Moon Kingdom to Earth, along with Luna, to awaken the Sailor Scouts and help them in their mission to protect the world.

Fun fact: Artemis is named after the Greek goddess of the moon, hunting, and chastity, which is fitting for his role as a guardian.


Artemis’s origin in the “Sailor Moon” series traces back to the Silver Millennium, the era of the Moon Kingdom that existed thousands of years ago. He, along with Luna, served Queen Serenity, the ruler of the Moon Kingdom, and the Sailor Scout, who were the protectors of the Solar System.


Artemis, just like Luna, is more than just a cat. They are both alien beings from the planet Mau, possessing higher intelligence, the ability to talk, and extended lifespan.

In the “Sailor Moon” series, there are instances where Artemis, along with Luna and Diana, are transformed into a human-like form. This transformation happens in the manga during the “Dream” arc and is also depicted in the “Sailor Moon Eternal” film, which is based on this arc. In this human-like form, Artemis appears as a young man with white hair.

Although they occasionally bicker and tease each other, Artemis and Luna share a deep bond through their goal of protecting the Sailor Scouts. Eventually, Artemis and Luna become romantically involved, and in the “Sailor Moon” manga and the “Sailor Moon Crystal” anime adaptation, they have a kitten together named Diana, who later serves as Sailor Chibi Moon’s guardian.

Artemis’ Special Powers

Artemis is no where near as powerful as the Sailor Scouts, but he does have a few special powers that are invaluable in the series.


Artemis can communicate with Luna and the Sailor Senshi telepathically, allowing him to relay important information or advice without being physically present.

Ability to speak to humans

Both Artemis and Luna possess the ability to speak human languages fluently, which is crucial for their role as guides and mentors to the Sailor Senshi.


In the “Sailor Moon” manga and “Sailor Moon Crystal,” Artemis has the ability to transform into a human-like form. This ability is used sparingly and typically reserved for special occasions or side-story episodes, but when he does transform, Artemis appears as a human with white hair, retaining his crescent moon symbol on his forehead. Artemis does not ever shapeshift in original 1990s anime series.

Does Artemis Ever Die?

Artemis does not die permanently; however, there is a moment in the manga and its adaptation “Sailor Moon Crystal” where Artemis, along with Luna and Diana, sacrifices himself to help the Sailor Scouts. During the final arc, “Sailor Stars,” the three guardian cats are turned to stone while protecting Princess Kakyuu. Later, they use their remaining power to create a shield to protect the Earth from a devastating attack, a selfless act that results in their apparent death, but they are eventually revived when Sailor Moon defeats the ultimate enemy, Chaos, and restores peace to the universe.
