Spock (mirror)

In the mirror universe, Spock was a Vulcan who served aboard the Terran Empire's ninth Sato Class warship, the ISS Enterprise (NCC-1701). He later went on to become Intendant of the Terran Empire, and is considered, by Terrans, to be one of the main reasons for the downfall of the Terran Empire at the rise of the Klingon-Cardassian Alliance.
