Star Trek: Fragile Glass

As the mirror Captain Kirk, Scott, Dr. McCoy, and Uhura return to their own reality, Spock arrests Kirk and assumes command of the I.S.S. Enterprise NCC-1701. Marlena questions Spock for not immediately killing Kirk, but the Vulcan feels the need to cover his bases and the two agree to an alliance…and perhaps more. Spock beams down to Halka and convinces the Council not to resist when Starfleet begins mining dilithium without the Halkans’ consent, thus sparing their civilization and allowing them to continue championing peace. Meanwhile, a Klingon war fleet led by Lord Skarl arrives in orbit, intent on destroying the Enterprise. In the brig, Kirk and Sulu ally to oust Spock, and take advantage of the Klingons’ diversion to escape and try to reclaim the ship. Their efforts fail, though, as Marlena uses the Tantalus field to eliminate most of Kirk’s loyal soldiers. Spock has Scotty connect the Tantalus field to the ship’s main power and uses it to wipe out the Klingon fleet with the push of a button. Kirk, Sulu, and Uhura storm the bridge, though they are defeated and Kirk is killed. Captain Spock, now with command of both the ISS Enterprise and a powerful weapon, and holding a treaty with the Halkans, is recognized by Starfleet command and begins an effort to reshape the way the Terran Empire operates.
