In the mirror universe, James T. Kirk (2233-2267) was a Terran officer in the Imperial Starfleet who commanded the ISS Enterprise in the 2260s. In 2267, Kirk became one of the first to crossover into the primary universe, an event which would serve as a crossroads for the future of the mirror universe.


Early lifeEdit

James T. Kirk was born in a farmhouse in Riverside, Iowa on Earth in 2233. (ST - Mirror Universe Trilogy novel: Dark Victory)

He had an elder brother George Samuel Kirk, Jr., whom he referred to as "Sam" and who later pursued a career as a scientist. As Sam had no interest in a military career and James had no interest in science unless he could manipulate it to make his life easier, neither brother had to worry about the other getting in the way of his career and having to be eliminated. (TOS - Mirror Universe short story: "The Greater Good")

In 2246, Kirk and his family moved to Tarsus IV. That year, the colony suffered a mass famine caused by the virogen plague and Governor Kodos ordered the execution of 4,000 colonists. However, 13-year-old James T. Kirk led a small gang of children to seize the food warehouses and executed Kodos. (ST - Mirror Universe Trilogy novel: Spectre)

This is contradicted by the novel "The Sorrows of Empire" and the RPG "Through a Glass, Darkly", in which Kodos is depicted as still being alive in the 2270s.

While at Starfleet Academy, Kirk murdered an upperclassman named Sean Finnegan, who had been bullying him, with the assistance of Simon Van Gelder. He later commented that "[e]ven death couldn't wipe that stupid grin" off Finnegan's face. (TOS - Mirror Universe short story: "The Greater Good")

Kirk was an early protege of Captain Garth of Izar. In 2254, immediately following his graduation from Starfleet Academy, the young Lieutenant Kirk used his mentor's influence to arrange an assignment on board the ISS Farragut. (Decipher RPG module: Through a Glass, Darkly)

Starfleet careerEdit

Kirk would serve on board the Farragut for three years under the command of Captain Stephen Garrovick. Garrovick took particular delight in humiliating Lieutenant Kirk in front of the entire crew. In revenge, Lieutenant Kirk arranged for Garrovick and two hundred of his crew to be killed by a dikironium cloud creature near Tycho IV after Kirk "hesitated" to fire the ship's phasers against the creature. He later claimed that the night after the massacre was the best sleep he'd had in years. (TOS - Mirror Universe short story: "The Greater Good"; Decipher RPG module: Through a Glass, Darkly)

In the RPG "Through a Glass, Darkly", Kirk is stated to have served on board the Farragut from 2254 to 2257, whereas the short story "The Greater Good" states that Kirk served until 2264.

In the early 2260s, Kirk was romantically involved with Dr. Carol Marcus and the two had a son, David Marcus. However, Carol would keep David's parentage a guarded secret in order to avoid Kirk finding out about him. According to Spock, if Kirk had ever found out that David was his son, he would have killed both David and Carol. (TOS - Mirror Universe novel: The Sorrows of Empire; TOS comic: "The Mirror Universe Saga"; Decipher RPG module: Through a Glass, Darkly)

Road to commandEdit

Several contradictory accounts have been given for when Kirk started serving on board the Enterprise and when he assassinated Captain Christopher Pike.

Through a Glass, DarklyEdit

Kirk moved up in rank to Lieutenant Commander following the Tycho incident and arranged to be assigned to the ISS Enterprise, under the command of Captain Christopher Pike, where he made the acquaintance of Lieutenant Spock, a junior science officer. While on a landing party, Kirk discovered the Tantalus field in the looted laboratory of a dying alien scientist. With this device at his command, Kirk began slowly and systematically working his way up the ladder of command on board the Enterprise.

By 2262, Kirk was first officer on board the ship and later that year he arranged for the "disappearance" of Captain Pike and assumed command of the Enterprise with Spock as his first officer. (Decipher RPG module: Through a Glass, Darkly)

Star Trek: Mirror UniverseEdit

In 2264, in the aftermath of the Farragut disaster, Kirk was promoted to Lieutenant Commander and placed on medical leave while the Farragut remained in Earth Spacedock, having yet to be assigned a new captain. Kirk used his time off to gather information about Christopher Pike, captain of the ISS Enterprise, in order to assassinate him and gain command of the Enterprise. With the help of Spock and Marlena Moreau, Kirk learned that Pike had plunged into alcoholism and was under the influence of the Talosians.

Kirk was ordered to report to what the Terran Empire euphemistically referred to as a "grief counselor." Although he was confident that Starfleet Command would not discipline him as his actions were consistent with Starfleet's rules of promotion, Kirk was concerned that the survivors of the dead Farragut crewman would attempt to seek their revenge by bribing the grief counselors. In order to avoid such an eventuality, Kirk requested that he be allowed to have the required psychiatric sessions with Doctor Simon Van Gelder, an old friend of his from Starfleet Academy who was by then the second-in-command of the Tantalus Penal Colony. Starfleet Command granted his request.

Borrowing one of the shuttles belonging to his brother Sam, who did not inquire as to the purpose to which James intended to put the shuttle, Kirk traveled to the Tantalus colony posing as a Bureau of Mental Hygiene official named Dr. James and visited Van Gelder. He agreed to give Kirk a positive psychiatric review on the condition that Kirk helped him leave the colony so that he would not be implicated in Tristan Adams's attempts to actually rehabilitate people (which were contrary to official Imperial policy). Once Kirk agreed, Van Gelder started a prison revolt as a distraction.

During the confusion, Kirk, Van Gelder and Marlena went down into the colony's vault where all of the personal items confiscated from the inmates were stored. It was in the vault that Kirk discovered the Tantalus field and tested it on Van Gelder, killing him.

Once Kirk transferred over to the Enterprise, Spock requested that Kirk eliminate Pike's first officer, Number One, who had had numerous conflicts with Spock and had him reprimanded, and promote him to the position of first officer of the Enterprise once he took command. Kirk agreed to these terms and then assassinated Pike and Number One, gaining command for himself and the first officer's position for Spock. (TOS - Mirror Universe short story: "The Greater Good")

Mirror Universe TrilogyEdit

Kirk was assigned as first officer aboard the ISS Enterprise in 2264, under the direct command of Captain Christopher Pike.

Kirk remained as first officer under Pike until 2266, when he seized upon the opportunity to kill him. Whilst out patrolling at the edge of the Empire, the ship encountered the First Federation vessel Fesarius, commanded by Commander Balok. Pike wanted to claim the vast Fesarius for himself and sent Kirk and a landing party over to acquire the vessel. They were greeted by Balok, but Kirk simply killed him and raided his laboratory for any useful technology. One piece of technology he came across was the Tantalus field, which Kirk was able to use to assassinate Pike and assume command of the Enterprise. (ST - Mirror Universe Trilogy novel: Dark Victory)

Captain of the EnterpriseEdit

In 2264, the Enterprise departed on a five-year mission of exploration and conquest under Kirk's command. (Decipher RPG module: Through a Glass, Darkly)

Kirk's first official action as captain of the Enterprise was to suppress the Gorlan uprising by completely destroying the planet Gorlan. Kirk ordered an orbital bombardment on the planet, killing almost every living thing on the planet's surface and turning the surface into rubble and glazed glass. Further bombardment from the imperial ship caused the planet to crack open like an eggshell and killed all who did not escape Gorlan. Only a few thousand Gorlan managed to escape the planet and they became space pirates.

In 2265, Kirk's second action as captain was the execution of 5,000 colonists on Vega IX after they threatened to secede from the Terran Empire. Responding to the crisis, Kirk's security forces were easily able to round up all of the conspirators. Kirk quickly realized that it was the children who had prompted their parents to stage the coup, having gained great powers of suggestion over their parents and other adult blood relatives due to exposure to the strange properties of a meteorite that had landed outside the main Vegan settlement, Orbis.

To teach the children a lesson about the responsibilities of power in a harsh world, Kirk had 5,000 parents executed and then recommended that imperial administrators round up the psychic children and ship them off to Vulcan for study and possible training as intelligence agents or even assassins. However, the shuttle carrying the children veered off course and was never seen again. (TOS episode: "Mirror, Mirror"; ST - Mirror Universe Trilogy novel: Preserver; Decipher RPG module: Through a Glass, Darkly)

Later that year, Kirk launched a devastating attack against the Romulan Star Empire which destroyed much of their industrial base, providing what was considered to be a "necessary show of force" against them. (Decipher RPG module: Through a Glass, Darkly)

At some point, Kirk was duplicated due to a transporter malfunction. He would later describe his duplicate as "weak-willed" and "simpering". (ST - New Visions comic: "The Mirror, Cracked")

During a visit to the planet Exo III, Kirk destroyed Ruk, the last surviving member of a society of androids which had turned on their masters and killed them. (TNG - Mirror Universe novel: The Worst of Both Worlds)

In 2267, Kirk executed Chief of Security Ben Finney for plotting against him. Afterwards, Lieutenant (j.g.) Hikaru Sulu assumed Finney's rank and position.

This is contradicted by the comic miniseries: "Mirror Images", in which Sulu is depicted as already being Chief of Security in 2264.

Shortly after Finney’s execution, Lieutenant Commander Spock seized control of the Enterprise and directed it on a course for the forbidden planet of Talos IV, after imprisoning Captain Kirk and Commodore Mendez of Starbase 11. This "mutiny" was actually a ruse by Kirk and Spock to allow the Enterprise to approach the planet and bombard it, in order to destroy the Talosians, whose power of mental illusion posed a threat to the Empire. For their actions, both men earned medals from the Empire and Spock was promoted to the rank of Commander.

When an imperial colony on Cestus III was attacked and occupied by the Gorn, the Imperial Starfleet, including the Enterprise, launched a retaliatory raid on the planet which was interrupted by the arrival of advanced alien beings who referred to themselves the Metrons. The Metrons forced Kirk and his Gorn counterpart into a duel to the death. Kirk won by fashioning a makeshift gunpowder weapon, but paused before killing him. Kirk wanted to torture the Gorn for information about his species before dispatching him. However, the Metrons interpreted his action as a show of mercy, and banished Kirk and the Enterprise from Gorn space by creating a vast energy barrier around it.

Later on, Kirk ended the conflict between Eminiar VII and Vendikar by bombarding both planets until they were forced to surrender to the Empire. He also dealt with a threat to Imperial mine workers on Janus VI, capturing the silicate creature stalking them and seizing its eggs for study. Kirk later put down a minor Klingon incursion into the Organia system before the Klingons could land on the planet Organia.

Later on, an incident caused Kirk to accidentally time travel to Earth in the 1930s. While there, Kirk saved Edith Keeler from her destined death in an automobile accident and then told her about the century's future history so that the two of them could rule together. During this time, Kirk and Keeler conceived a son, James T. Keeler. However, Kirk's crew thwarted his plans for world domination by rescuing him from his temporal marooning.

When the Deneva colony was invaded by neural parasites, Kirk destroyed most of the life on the planet in order to guarantee the eradication of the parasites. Kirk justified his decision based on Imperial policy, claiming that the fact that his brother Samuel lived at the colony, and that he and Samuel hated each other, had no bearing on his actions. (Decipher RPG module: Through a Glass, Darkly)

When his chief engineer Montgomery Scott was accused of the brutal murders of three women on Argelius II, Kirk ensured that the charges against Scott were dropped without an investigation taking place. (TOS - Mirror Universe novel: The Sorrows of Empire)

As in the primary universe, the murders were presumably committed by Redjac while in control of Scott's body.

Kirk later oversaw the conquest of Gamma Trianguli VI and Coridan as new subjects of the Empire. (Decipher RPG module: Through a Glass, Darkly)

Later, Kirk visited the planet Halka. The Empire had noted the Halkan homeworld's vast dilithium reserves and threatened to destroy the Halkans if they did not comply. When Kirk's landing party attempted to beam up from the Halkan homeworld, an ion storm crossed him with his parallel from this universe, beaming him right inside his duplicate's clothes in a one-in-a-million transference, which read to Winston Kyle's board as a "wobble" in the power beam of the transporter.

He found himself aboard the USS Enterprise in a different world than the one that he knew. Upon his counterpart's return to the primary universe, Spock noted it was more difficult for the barbaric mirror universe landing party to behave civilized than it was for the civilized crew to feign barbarity on the other side. After being imprisoned by Spock, he offered him fantastic bribes to get his command back. Spock proceeded to place the captives on the transporter, to wait for when the crew from his landing party reciprocated the action, and beamed themselves back into the places of the duplicates.

After the landing parties returned to their respective universes, the Spock of the primary universe told his Captain Kirk and Doctor Leonard McCoy that he found their counterparts to be "brutal, unprincipled, uncivilized, treacherous; in every way splendid examples of Homo sapiens, the very flower of Humanity." (TOS episode: "Mirror, Mirror")

During the second known crossover in 2370, Intendant Kira told her counterpart Major Kira Nerys that Kirk's situation changed radically upon his return. The Spock from his own universe had relieved him of command and gained Kirk's Tantalus secret and the loyalty of his woman. Kirk's counterpart had strongly encouraged them to attempt to overthrow and change the Empire's negative effects on the galaxy.

Upon relaying this information to Dr. Julian Bashir from the primary universe, he noted that the events leading to Kirk's overthrow was something he read at Starfleet Academy. (DS9 episode: "Crossover")

Star Trek: Mirror UniverseEdit

Upon Kirk's return to his own universe, Spock attempted to reason with Kirk to spare the Halkans for their refusal to trade with the Empire. He made the logical argument that annihilating the Halkan civilization would hinder the Empire's mining of the planet, only to be ignored by a vengeful Kirk. Spurred by the words of the parallel Kirk and what he'd seen in his mind meld with the parallel McCoy, Spock strangled Kirk to death in his own quarters and assumed command of the Enterprise. Kirk's corpse was disposed of with the Tantalus Field and his confederates (including Security Chief Sulu) were eliminated. (TOS - Mirror Universe novel: The Sorrows of Empire)


The Terran Empire named the capital city of Cestus III after Kirk, although the Klingon-Cardassian Alliance would change the city's name from Kirk City to Gorkon City after the fall of the Terran Republic. (VOY - Mirror Universe novel: The Mirror-Scaled Serpent)

By the 24th century, Kirk was an important historical figure, especially to Terrans, although opinions concerning him were mixed. Noonien Soong considered him an example of a military officer who deprived Terran science of valuable discoveries. However, Jean-Luc Picard held Kirk in high esteem, and in fact wondered if things would have gone better for the Terran race had Spock been assassinated instead of Kirk. Picard also wondered if Kirk's actions on Exo III might not have prevented Terrans from being conquered by androids, rather than the Alliance. (TNG - Mirror Universe novel: The Worst of Both Worlds)

An earlier novel, Dark Mirror, which featured Picard, did feature an alternate history where Kirk killed Spock. In that permutation of the mirror universe, the Terran Empire survived until well into the 24th century and the Alliance never rose to power.

Mirror Universe TrilogyEdit

In this alternate reality, Kirk became Starfleet's commander-in-chief within five years of the transporter accident, and five years later became Emperor Tiberius by assassinating Androvar Drake. He only reigned for a few months before being overthrown by Spock, but in that short time he became the most depraved dictator in the Terran Empire's history. He instigated a number of purges, killing many of his former officers, including Marlena Moreau. After his ousting he went to the Klingons and Cardassians and talked them into helping him reclaim the Empire. As a result humans and Vulcans became enslaved by the Klingon-Cardassian Alliance. In the tradition of Commander Jonathan Archer, plagued and growing obsessed with his counterpart, Tiberius increasingly despised his own over the years, eventually calling him and all that dwell in the other universe "ghosts". (TOS novels: Spectre, Dark Victory)


In this timeline Kirk died fighting the Klingons in the Mutara sector. (STA novel: Three)
