Mistress 9

Mistress 9 was awakened when Hotaru's body could no longer stand the effects of being an animated corpse. She stole Chibi-Usa's Silver Crystal when Chibi Usa came to save her friend from being killed by the outer senshi. Mistress 9 is Master Pharoah 90's partner from the old world. Her job is to bring about the ressurection of Master Pharoah 90. When he is resurrected, she tries to cast off Hotaru's body, but Hotaru's remaining soul will not allow her to reign free and traps her within the body that was once Hotaru. When Hotaru's soul escapes, Mistress 9 is then transformed into a huge monster, which lends all it's strength to Master Pharoah 90 and the Tau Star System. It is then killed by Super Sailormoon and Sailorsaturn.
