In the mirror universe, Lieutenant Hikaru Sulu (2237-2267) was the Terran security chief, helmsman and second officer aboard the Terran Empire starship ISS Enterprise, under Captain James T. Kirk. Sulu had a scar on his face from unknown reasons and had an infatuation with the ship's communications officer, Lieutenant Nyota Uhura.
In 2267, four crewmembers of the USS Enterprise crossed over into the mirror universe during a transporter malfunction while attempting to transport through an ion storm. In their attempt to escape, it was the mission of Lieutenant Nyota Uhura to distract Sulu from his security display, which she was successful in manipulating.
When Spock received orders to assassinate Kirk for disobeying the Empire's orders to annihilate the Halkans, Sulu arrived with a security squad and had previously warned Spock that if the Vulcan was not able to command the ship, he would take command. Sulu tried to assassinate both Spock and Kirk and make it appear as though they killed each other after a fierce battle. He hoped to become the Enterprise's captain, and undoubtedly make Uhura the "captain's woman".
Sulu would, in turn, be defeated when the "captain's woman", Marlena Moreau, utilized the Tantalus field against Sulu's posse, allowing the four members of the USS Enterprise to return back to their universe. (TOS episode: "Mirror, Mirror")
Soon after the four crewmembers returned to their own universe, Sulu was "neutralized" by Lieutenant Robert D'Amato at the same time that Spock killed Kirk, solidifying Spock's command of the Enterprise. (TOS - Mirror Universe novel: The Sorrows of Empire)
In 2293, Sulu commanded the ISS Excelsior. Sulu had attempted to take over the Terran Empire and was deemed a traitor. While being chased by the ISS Enterprise-A, which was commanded by Pavel Chekov, who wanted to kill Sulu for not having included him in his plans to take control of the Empire, Sulu and his crew were caught in the Janus Vortex. During the event, he and his crew were transported into another universe, where they exchanged places with their counterparts in that reality.
Now in command of the USS Excelsior, Sulu attempted, and nearly succeeded, in leading the Klingons and the Romulans into a war against the Federation. However, before he was able to do so, the USS Excelsior was pulled inside the Janus Vortex, where they encountered their counterparts. In-between dimensions, a battle erupted between the two until Sulu's counterpart deployed a dilithium warhead which catapulted both crews back to their own realities.
