. When the Vulcans landed and made their peaceful introduction, however, Cochrane killed the leader with a concealed weapon, then led the townspeople in commandeering the Vulcan ship.

The special opening credits sequence used for "In a Mirror, Darkly" chronicles the history of human warfare and the interstellar domination of the Terran Empire, as opposed to the regular opening sequence depicting peaceful exploration. One of the more notable scenes is a Terran Empire flag being planted on the moon, which may or may not be intended to be in 1969. (The spacesuit being worn is the same as that which the Enterprise crew wears, but commentary on the episodes by their producers indicates that this was simply a matter of convenience, as the CGI model for that suit had already been created.)

 episode "The Alternative Factor". In this episode, the crew encounter a man named Lazarus who appeared to undergo extreme shifts in behavior. After a time, it was discovered that there were two men, one from an alternative antimatter universe who was calm and rational, and another from our universe who was irrational. Both men had a ship that had the ability to send people into the other's universe. The Lazarus from the alternative reality said that there was a corridor of sorts between the universes where he and his counterpart could safely meet. If they met outside the corridor, both universes would be annihilated due to the contact between matter and anti-matter. Lazarus arranged with Captain Kirk

 to trap both him and the other Lazarus in the corridor forever by having Kirk destroy the ship, and at the same time, the ship in the other universe was destroyed as well. Both men were trapped forever in the corridor, one sane, and one not.

The Mirror Universe was first introduced in the original Star Trek episode "Mirror, Mirror". It was established that in the Mirror Universe the United Federation of Planets counterpart was the brutal Terran Empire, run by humans and their Vulcan allies. In the Mirror Universe, the term "Terran" is predominantly used for humans.

 had been turned down by the peaceful Halkans, who did not want to trade for dilithium. They feared the use of the material for war. An ion storm causes a beam-up to go awry, switching the crew with their alternates.

Kirk tries to save the alternate-Halkans from destruction; the common tactic used by the Terran Empire when meeting resistance. He suffers several assassination attempts.

Both Spocks find out the dual nature of the affected officers and work on a way to get them home in time; there is a limit.

Before leaving the Mirror Universe, Kirk gave an impassioned speech in which he told Mirror-Spock that because the Empire would die in a few hundred years, that it was illogical, and Mirror-Spock was illogical for supporting the Empire. He asks Mirror-Spock to work for change, and Mirror-Spock replied that he would consider Kirk's proposal.

About a year after his first crossover, Kirk unknowingly experienced a second encounter with the mirror universe. In "The Tholian Web", the Enterprise encounters the crippled Constitution-class U.S.S. Defiant, which is phasing in and out of existence with Kirk's reality as a result of a localized spatial anomaly. Kirk leads an away team and discovers the crew is dead as a result of the anomaly's effect on the brain. As the Defiant begins to shift out of reality, the away team is beamed out, but Kirk is somehow trapped in the interphase. The Tholians claim this particular area of space and attempt to ensnare the Enterprise in their energy web, but the Enterprise, under the command of Spock, is able to escape and retrieve Kirk from between dimensions. Kirk remarks that during his experience the Defiant was pulled away into another dimension.

What Kirk never knew, but which was established in the Enterprise episode "In a Mirror, Darkly", was the Tholians of the Mirror Universe managed to open a dimensional rift hoping to steal technology from alternate realities. Their efforts also created a temporal rift, connecting from a universe 110 years in Kirk's past. The mirror Tholians sent out a distress call to lure a spacecraft and ensnared the Defiant in their trap, eventually pulling it completely into the mirror universe. So determined were the Tholians to unlock the technological secrets of the future ship that work crews began dismantling the ship before moving the bodies of the crew, several of whom were discovered by the ISS Enterprise away team in the same positions as Kirk had found them.

As a side note, the Tholian tactic of stealing future technology was paralleled in the regular Trek universe. In "Future Tense", 22nd century Tholians attempt to capture a 31st century Federation vessel but are thwarted by Archer's Enterprise.

second-season episode "Crossover", and turned into a story-arc that spanned into the final season, with five Mirror Universe episodes over the course of seven seasons.

On Deep Space Nine, which takes place over 100 years after the original contact with the Mirror Universe, it was revealed that drastic changes had occurred in the Mirror Universe because of the interference of the regular universe's Kirk. Before he left the Mirror Universe, James T. Kirk planted seeds of doubt in the Mirror-Spock's mind about the Terran Empire's brutal tactics. Kirk noted that Spock was a man of honor in both universes, and the Mirror-Spock listened to Kirk's urging for reform. Mirror-Spock's future role on Enterprise and the fate of Mirror-Kirk are unclear, though some have suggested that Mirror-Kirk was assassinated (and was shown in a non-canon Star Trek comic). Mirror-Spock then went on to become Chief of State of the Terran Empire. Mirror-Spock introduced many popular reforms that largely ended the iron-fisted rule of the Terran Empire, especially a vast demilitarization program. However, these reforms were very ill-timed.

Not long after Mirror-Spock's demilitarization drive, the Terran Empire encountered the Alliance. In the Mirror Universe, the Alliance is a unified government of the Klingon

This implies that the Romulans are an independent empire, much like they are in the "prime" reality or universe. It also means that, unlike other races such as the Vulcans and Andorians, the Romulans were able to resist the Terran Empire and to survive the mirror equivalent of the Earth-Romulan War, assuming that one took place to begin with.

The Bajorans of the Mirror Universe were ruled by the Terran Empire but later sided with the Alliance and became masters of Terran slave forces. Notable among them was Intendant Kira, the counterpart to the normal universe's Kira Nerys. Intendant Kira was a ruthless, sadistic hedonist; she was outwardly bisexual

Smiley never married or had children, but eventually became a high ranking cell leader in the Terran Resistance — and after Mirror-Sisko's death, perhaps the leader.
  • Bareil Antos is also still alive, but never became a Vedek (religious leader). In the mirror universe, Bareil was a thief and petty criminal.
  • Vic Fontaine also makes an appearance, working alongside Mirror-Ezri. Inexplicably, he is not a hologram in the Mirror Universe, and the moment is played as comical. He was killed by Bashir shortly after making his appearance.


Eventually, the Terran Resistance captured Mirror-Terok Nor and used it as a base of operations, and built a Mirror-Defiant using plans stolen from the normal universe.

Novels

Besides the various canon productions depicting the mirror universe, it was the basis of many novels and comics, however as each TV series made its own mark on the continuity of the Mirror Universe the histories and futures established for the universe in non-canon works began to contradict canon. Most recently several Mirror Universe novels have been published in the DS9 Relaunch series and the Star Trek: Mirror Universe series which integrate new non-canon stories into the complete canon Mirror Universe.

The I.S.S. Enterprise obtains the Genesis technology developed by Dr. Carol Marcus then enters our universe to spearhead the Empire's intended conquest of the Federation. Meanwhile, in the "real" universe, Captain Styles of the Excelsior has arrived at Regula I, where Kirk and crew have found temporary safe haven, to take them back to Earth to stand trial for their mutinous actions (as depicted in Star Trek III). When they encounter a mystery attacking ship, Styles overconfidently believes the Excelsior can defeat the attacker, which is an "outdated" Constitution-class ship, but it turns out to be the I.S.S. Enterprise under the command of Mirror-Kirk. The Mirror-Enterprise crew easily overpowers the inexperienced Excelsior crew, taking over the advanced vessel, and Mirror-Kirk dispatches Mirror-Spock (who despite his words at the end of "Mirror, Mirror" had elected to return to Mirror-Kirk's side after all, after logically deducing that the efforts of any one single man would be a useless gesture against the Empire). Mirror-Sulu and Mirror-Chekov travel to Vulcan (aboard Kruge's Klingon bird-of-prey, captured by Kirk during Star Trek III and confiscated by Styles when taking custody of the Enterprise survivors) to find Spock, still recovering from the fal-tor-pan ritual on Vulcan. Kirk and his own crew manage to escape and take over the I.S.S. Enterprise, which is destroyed by remote control by the Mirror-Kirk; the real Kirk's crew survives by escaping in the ship's saucer section.

After retaking the Excelsior from Mirror-Kirk (and placing the Mirror-Enterprise crew in stasis
Stasis (medicine)

), Kirk takes command of Excelsior and takes it to the Mirror Universe in a gambit of impersonating Mirror-Kirk yet again. His plan is to break the back of the Empire's planned invasion by taking command of the Imperial fleet aboard Excelsior, then turning on the fleet at the critical moment. One Empire officer, a Captain Blaine, is suspicious of Kirk's intentions; however, rather than suspecting Kirk is in fact his counterpart from the other (our) universe, he is familiar with Mirror-Kirk's history of advancing through the ranks by use of treachery and intrigue and thinks Kirk is out to take control of the Empire for himself.

 researches Imperial history to help familiarize the crew with the Mirror Universe and its history, so as to better portray their own counterparts. Her research reveals the likely point of divergence between the two universes - the Romulan War. In our universe, Earth and Romulus fought their war in deep space. In the Mirror Universe, the war was fought in Earth's solar system, and Earth lost. The Romulans held Earth for ten years until a resistance overthrew them. This resistance did not disband once the Romulans were deposed, however; rather, its leaders proclaimed that Earth would no longer be conquered, but rather would be the conquerors themselves. Thus did the resistance movement form the seeds of what would eventually become the Terran Empire.

Meanwhile, Mirror-Spock reaches Vulcan, where he engages in a mind meld with the recovering Spock of our universe. However, once Mirror-Spock touches his mind, Spock is able to reflexively initiate a meld of his own. In the ensuring battle of minds, Spock draws strength to restore his mind, and at the same time, Mirror-Spock becomes reconciled to "our" Spock and the two make common cause to stop the Empire. The two Spocks use the captured Klingon ship to cross into the Mirror universe.

Also seen during this storyline is the counterpart of Kirk's son, David Marcus - still very much alive in the Mirror Universe, and leading a resistance cell against the Empire.

The Empire accepts Kirk's proposal to align with the Romulans and Klingons to defeat the Federation, Klingons and Romulans. However, Kirk and Scott have a plan to disable the entire fleet of Empire ships, then, when sufficiently defeated, disable the Romulan and Klingon ships (correctly suspecting both parties would turn their guns on Excelsior once the battle had ended) and return home. The empire, however, already had its own Excelsior built; they had studied the Federation ship earlier in the arc, and used the data gleaned from this examination for help in making their own Excelsior operational. The Mirror-Excelsior is under the command of Captain Blaine, who had evidently convinced others within the Empire's Admiralty of Kirk's duplicity. Fortunately, Scotty had deliberately screwed up the Excelsior's systems before Empire technicians studied them, giving their scanners false readings; as a result, the Mirror-Excelsior cannot draw enough power to operate and is easily defeated.

The Excelsior then returns to the Federation, having dropped off their mirror counterparts in shuttles. When Mirror-Kirk awakens, he tries to contact the nearest Imperial vessel for assistance - not realizing he and his crew have been branded as traitors after the real Kirk's actions left the Imperial fleet crippled. The I.S.S. Nogura picks up Mirror-Kirk's distress signal, and after verifying the identity of those aboard, destroys the shuttle, killing all aboard. Of the Mirror-Enterprise crew, only Mirror-Spock survives, and he elects to join David Marcus' resistance cell.

After returning to his own universe, Kirk gives a reporter an exclusive on how he and his crew saved the Federation from an invasion about which they would have never known. Her reports in the mass media paint the Enterprise survivors as heroes, much to the consternation of Starfleet brass who still wanted Kirk court-martial

ed. In the end, facing a public-relations nightmare if they proceeded with a full trial, Starfleet reluctantly gives Kirk full command of the Excelsior, ostensibly for an extended shakedown cruise to help work out all the bugs in its system. With the exception of Spock (who is assigned to a command of his own, the science vessel Surak), Kirk's entire crew joins him on this new mission.

-- is set sometime after the original series episode "Mirror, Mirror". In the game, Captain Hikaru Sulu and the crew of the U.S.S. Excelsior swap places with the crew of the I.S.S. Excelsior thanks to a localized stellar ion storm. They are hunted by Mirror-Chekov, who commands the I.S.S. Enterprise, and assisted by the Mirror-Klingons and Mirror-Romulans. During their trek home, the Excelsior crew encounter Mirror Universe variations of the original series' missions, including the M-5 multitronic computer, a giant space-amoeba and a Doomsday Machine, although the latter is under the escort of the ISS Constellation and ISS Intrepid.

While the game takes place at some point during the era of the Star Trek films, it is unclear exactly when. The Enterprise has not yet been decommissioned, but Sulu is in command of the Excelsior, placing the game somewhere in the timeframe of "Star Trek V: The Final Frontier" and "Star Trek VI: The Undiscovered Country". Spock has not yet completed his coup d'état—the Empire contacts Mirror-Chekov several times during his mission to capture Sulu—but there is still much time for that to occur in the Mirror Universe timeline. There is no indication the character of Kirk, either version, is involved in the storyline.

Star Trek: Starfleet Command is a computer game based on the table-top wargame Star Fleet Battles. It simulates starship operations, and ship-to-ship combat and fleet warfare in the Star Trek universe....

, a player who eventually joins the Starfleet Special Forces during the Federation campaign will be launched on a series of missions involving the mirror universe. It begins with an encounter involving the destroyer USS Boston during an experimental "star tap" test, capturing the player's counterpart (in exactly the same ship as the player's main vessel) when the player is accused of crimes against other empires, and a showdown on Earth against a fleet of Doomsday Machines led by the mirror counterpart of Matthew Decker, who is supreme commander of the Imperial forces.

Star Fleet Command II

The game Star Fleet Command II features a series of scenarios in which the Mirror Universe Imperial Starfleet attacks the Federation. At first, the Imperial vessels show up and cause quite a stir. A destroyer is taken into custody, revealing all sorts of strange things such as an agony booth. Captain Decker is captured in one of the scenarios and eventually, the player must fight himself and an identical ship. Commodore Decker is the leader of the invaders and in an ironic twist, reactivates a squadron of "planet killers", c.f. "The Doomsday Machine" of TOS in order to destroy Earth.

Other ramifications

While in the "Alternative Factor", the Lazarus of the alternate universe said that to meet his counterpart would cause the destruction of both his and our universe, while in later episodes characters met their counterparts in the Mirror-Universe and the meetings did not cause any apparent damage to either universe. This apparent discrepancy is explained by the explicit statement made in the episode that the alternate Lazarus is from an anti-matter universe; it has long been established in "Star Trek" canon that physical contact between matter and its anti-matter counterpart is catastrophic.
