In the alternate mirror universe James T. Kirk was the commanding officer of the Dominion Grand Fleet starship DSS Enterprise. Much like in the "primary" mirror universe, this version of Kirk was switched with his primary universe counterpart, though unlike the "primary" mirror universe, the primary Kirk's attempts to cause reform failed, and Spock was caught attempting to kill Kirk. Spock was quickly executed and succeeded as first officer by Hikaru Sulu. (Star Trek: Remington)
