Spock (mirror)

In the mirror universe, Spock was first officer of the ISS Enterprise in 2267. Like his counterpart, Spock was a logical being who was loyal to his captain, James T. Kirk, and chose to warn him when he was ordered by the Terran Empire to kill him and take command if he did not launch an attack against the Halkans in retribution for their refusal to negotiate with the Empire.

Based on his captain's apparently erratic behavior, Spock correctly deduced that Kirk had actually been accidentally replaced by his counterpart from our universe, and devised a means of returning Kirk, Scotty, McCoy, and Uhura to their original ship.

Before Kirk left, believing that Spock would one day become captain of the Enterprise, he planted a seed of doubt about the inevitability of the Empire, asking Spock if violence was the only logical answer. Spock promised to consider Kirk's words. 

As Kirk predicted, Spock later on became the captain of the Enterprise. Spock used the ship as a power base to accumulate influence, and eventually rose to become leader of the Terran Empire. He instituted major reforms, turning the Empire into a more peaceful and less aggressive power. Unfortunately, Spock's reforms left the Empire unprepared to fight the united Klingon-Cardassian Alliance, who conquered the entire Terran Empire, enslaving the Terrans themselves as well as the Vulcans. 

Other continuities
In A Debt of Honor Spock went on to become the Empire's Commander-in-Chief as portrayed on DS9, but was overthrown by the Imperial Starfleet shortly thereafter because of the influence the Halkans carried in his government.
