Pharaoh 90  

Master Pharaoh 90, 師・ファラオ90

Master Pharaoh 90 (師・ファラオ90, Masutā Farao 90?) is a malevolent alien from "Tau Ceti Star System." Its origins are unknown and it appears as a huge black sphere with tentacles. In the manga, its goal was to merge itself with Earth and make it its home. However, in the anime, it wanted to destroy Earth by bringing about the Silence. It provided the daimon egg of Mistress 9 to Professor Tomoe, taking advantage of his desire to save his daughter. In reality, Pharaoh 90 simply needed a body for Mistress 9 so that she could open a portal for it. The character was destroyed by Sailor Moon and Sailor Saturn in the anime but driven back to Tau Ceti and sealed away forever in the manga. Like all of the head villains in the manga, Pharaoh 90 is later revealed to be an incarnation of Chaos, the ultimate enemy of the series.
