Daughter of Zeus and Leto, Artemis is the virgin goddess of the hunt, child birth and fertility, also a member of the Twelve Olympians, together with her twin brother, Apollo, the god of arts. Depicted as a beautiful young woman, she is always said to carry her silver bow and arrows, and one of her main tasks was to protect the forests and hills. The deer and the cypress were sacred to her. As one of the most venerated deity in the Ancient Greece, her figures appears constantly in various myths, usually as the one who executes punishments upon mortals who broke their oaths or has offended the gods. All of her female followers are said to take a vow of maidenhood. Callisto was one of Artemis' loyal companions, but Zeus raped her and as a result, she is transformed into a bear by Artemis. Orion, another loyal companion who was also a valiant hero, was killed by a scorpion. Artemis then asked her father to resurrect him, and Zeus placed him among the stars. Later in history, she started to be associated with the Moon, overshadowing Selene, the personification of the Moon itself. She is known as Diana in the ancient Rome.
Artemis was worshiped as a many-breasted earth mother in Ephesus.
Artemis is one of the four Deities exclusive to the Kyūyaku version of Megami Tensei II, alongside Zeus, Leto, and Apollo. She roughly has the same stats as Vishnu.
Shin Megami Tensei IMAGINE
"One of the twelve Olympian deities of Greek mythology. The goddess of hunting and virginity. She is also recognized as a moon goddess, and is identified with the Greek goddess Selene and the Roman goddess Luna. She and her twin brother, the sun god Apollo, are the children of Zeus and Leto. Artemis is an expert archer and bears the title "Lady of the Long Arrow." The arrows she shot were said to kill their targets painlessly. Strong-willed, she was also given to pitiless acts of cruelty. In ancient times, the moon was though to possess great magic power. Because the moon changes its face as it waxes and wanes, it was seen as another face of Artemis, who formed a trinity along with the underworld goddess Hecate and the moon goddess Selene."

Artemis is the ultimate Persona of Maya Amano. In order to get her, the player must successfully collect the Blue Swan Mask inside Mt. Iwato. Artemis' appearance seems more futuristic with the polygons attached onto her body parts with violet blue and white serving as primary colors, in contrast to Maya's initial persona, Maia, who wears traditional clothing in red and black. Artemis reflects all magical attacks, but in turn is weak against physical attacks. Her attacks consist in dealing Ice damage, and the Crescent Mirror can be used to perform the Grand Cross fusion spell.

Artemis returns as Maya Amano's ultimate Persona, with minor cosmetic changes. She can only be summoned once her material card has been acquired on Mt. Iwato. Her stats remain almost unchanged, but her skills have been altered somewhat.
