Spock (mirror)

Half-Vulcan first officer on the I.S.S. Enterprise in the mirror universe who correctly deduced that the crewmembers who returned from Halka were not his own people, but counterparts from a United Federation of Planets. Along with [[Marlena Moreau (mirror) he helped them return to their own universe. Before returning home, Captain Kirk of the U.S.S. Enterprise urged Spock to work to reform the Terran Empire into a civilized society to avert its predicted collapse.

In one fan's timeline, Spock went on to become the Empire's commander-in-chief, but was overthrown by the Imperial Starfleet shortly thereafter because of the influence the Halkans carried in his government.
