|Commander Spock aboard the ISS Enterprise|
|Title:||First officer, science officer|
In the mirror universe, Spock was a Vulcan Starfleet officer who served on the ISS Enterprise, rising through the ranks to command that vessel before gaining suzerainty of the Terran Empire. Under his leadership, the Empire enacted many reforms which ultimately left it defenseless to an invasion by the Klingon-Cardassian Alliance. (TOS: "Mirror, Mirror", DS9: "Crossover"; Glass Empires)
Fan continuities[edit | edit source]
A Debt of Honor continuity[edit | edit source]
In A Debt of Honor 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. His katra was given to his Federation counterpart, apparently resulting in the two Spocks becoming a single individual. ("The Gift").
In Star Trek: Remington continuity, Spock was the first officer and science officer of the Dominion Grand Fleet's DSS Enterprise in an alternate mirror universe. Kirk's attempt to reform the Dominion was not successful and Spock was executed for attempting to start a revolution against the Dominion. He was executed by and succeeded as first officer by Hikaru Sulu.
- The Kirk who crossed over to the Dominion's mirror universe was from the REM primary universe, not the standard Trek primary universe.
In this continuity, Spock mutinied against Kirk after failing to persuade the captain not to exterminate the Halkans, an action that also caused the Andorians to rebel against the Empire. Spock saw this as evidence of the Empire's predicted decline and fall. Spock rejected Marlena Moreau's suggestion to use the Tantalus Field against Kirk as he believed that would make him as bad as the captain. Instead, Spock had Moreau join him in auxiliary control where he organised a resistance against Kirk. In the process, he recruited Montgomery Scott and Pavel Chekov.
Spock eventually agreed to meet with Kirk to discuss terms. However, this was a trick by Kirk to attempt to eliminate Spock. However, Spock tricked the captain into broadcasting his disdain for the crew over the intercom, which finally caused the majority of the crew to mutiny. After overthrowing Kirk, Spock gave the captain the shuttlecraft Galileo to transport himself and other unwanted crewmembers off the ship. Having ejected Kirk, Leonard McCoy, and Hikaru Sulu, Spock took over as captain and led a resistance against the Empire in an attempt to reform it. (Star Trek Continues: Fairest Of Them All)
