In the mirror universe, Hoshi Sato III (2248-2277) was a female Terran who was the Empress of the Terran Empire, and the last of the Sato Dynasty. Like her predecessor Hoshi Sato II, she was a clone of Hoshi Sato I. She reigned from 2267 to 2277, at which time she was killed and usurped by Spock then seized the Imperial throne for himself.

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.
