Mistress 9

Mistress 9 is a Daimon from Tau Nebula; an evil spirit who serves Pharaoh 90. She is an evil female entity from "Tau Star System" who has come to Earth to help open a gateway for her master, Pharaoh 90. She possesses Hotaru Tomoe's body (to varying degrees of intensity). After taking control of Hotaru's body, she ages it up to that of a 30-year-old with incredibly long dark hair, purple eyes, and dark purple lipstick. She wears a dark blue sleeveless top with white beads and a long white dress. She also wears earrings with white beads. The Death Busters are frequently striving to awaken Mistress 9 deep within her host, Hotaru. When Hotaru meets Chibiusa and the latter shows her the Silver Crystal, Mistress 9 becomes aware of its power and later steals it from Chibiusa (along with her soul), sending her into a comatose state.

When Mistress 9 overpowers Hotaru's mind and body, it becomes that of a grown woman. Her facial features are maniacal and there is little resemblance to the girl whose body she has taken over. Her purpose is to create an opening to the Tau Ceti Star System so that Pharaoh 90 can access and assimilate himself into Earth. her arch enemy is sailor moon. she is the supreme commander of the mighty female lords army
