Pharaoh 90

The animated version looks nothing like its manga or Crystal counterparts. Here it is a colossal, planet-sized sphere of black energy trailing dark tentacles, with no eyes to speak of, communicating only in growls and low moans. At its center it can tear open a vast hole and loose its attacks straight through that opening.

Its single obsession is unleashing the Silence upon Earth, an unstoppable wave of ruin, and it counts on the planet's destruction to draw the Holy Grail to it. Beneath that goal runs a streak of cruelty and calculation: it steers Professor Tomoe into hosting Germatoid and plants Mistress 9 inside Hotaru. Loyalty means nothing to it, and it registers not a flicker of feeling when one of its own energy blasts badly wounds Mistress 9.

The entity supplies Professor Tomoe with the Daimon pod carrying Mistress 9 and sends Germatoid to seize the professor's body after a laboratory blast engulfs him and his young daughter Hotaru. Its scheme relies on Tomoe harvesting Pure Heart Crystals to revive Mistress 9, the Messiah of Silence, so she can claim the Holy Grail and call the Silence into being. Once that groundwork is laid, it begins wiping out all life. Struck from Earth, it answers with a massive beam fired from orbit, strong enough to nullify Moon Cosmic Power, and after the Grail summons it, sweeping energy blasts carve open the ground in every direction.

Hotaru undoes Mistress 9 and rises as Sailor Saturn, slipping inside Pharaoh 90 to strike its core. Unable to keep Saturn from spending her own life in the effort, Sailor Moon produces a Pure Heart brighter than the Holy Grail itself and becomes Super Sailor Moon. Carrying the strength of the other Guardians, she enters the entity at the last moment and adds her power to Saturn's final blow, wiping it out for good. Many take it to be the Silence itself given form.
