Pharaoh 90

Pharaoh 90 is the final antagonist of Sailor Moon S, and the one behind all the events. He had Germatoid possess Doctor Tomoe, and his most powerful servant, Mistress 9, the Sovereign of Silence, possess Tomoe's daughter Hotaru. Mistress 9 and the Bureau of Bad Behavior wanted the Purity Chalice to awaken him, but Sailor Moon got it first.

Eventually Mistress 9 was able to get the Purity Chalice and awaken Pharaoh 90, who came to Earth. Sailor Moon attacked him, but he was unaffected and blasted her with a red energy wave. He also shot an energy wave at Mistress 9, but Sailor Moon protected her, as killing Mistress 9 would kill Hotaru as well. Pharaoh 90 began to bring the Silence about the world to destroy it. Hotaru was able to overpower Mistress 9 from within, destroying her, and awaken as Sailor Saturn. She attempted to destroy Pharaoh 90 from within by destroying his core, but was unable to. Sailor Moon received power from the other Sailor Scouts, transformed into Super Sailor Moon without the Purity Chalice, entered Pharaoh 90, and destroyed his core, completely destroying him.

Pharaoh 90 has the appearance of a giant dark energy orb.
