In the mirror universe, Hoshi Sato III (2248-2277) was a Terran female who ruled as the Empress of the Terran Empire. Like her predecessor Hoshi Sato II, she was a clone of Hoshi Sato I. She was the last of the Sato Dynasty. Empress Sato III reigned from 2267 to 2277, at which time she was killed using the Tantalus field. Grand Admiral Spock then seized the Imperial throne for himself. (TOS - Mirror Universe novel: The Sorrows of Empire)
The Vulcan T'Lara owned holovids of Sato's death, and showed them to Keiko Ishikawa prior to 2375. Keiko's lover Miles "Smiley" O'Brien, the leader of the Terran Rebellion, was sceptical of her claims that Spock had usurped the throne by making the Empress vanish into thin air.
