Between 2264 and 2270, the USS Enterprise (NCC-1701) was under the command of Captain James T. Kirk. During his tenure as captain, the Enterprise was a major component in many events of Alpha Quadrant history, as well as minor, run-of-the-mill missions. Below is a list of all adventures undertaken by the Enterprise over a six-year period, including the historic five-year mission from 2265 to 2270.



Stardate 1278.4
In an official change-of-command ceremony, Captain James T. Kirk relieved Fleet Captain Christopher Pike. (TOS novel: The Captain's Oath)
Kirk remembered this as the only time he'd met Pike. (TOS episode: "The Menagerie")
Two slightly different versions of the ceremony occur in TOS novel: Enterprise: The First Adventure and TOS comic: "All Those Years Ago...". Since "All Those Years Ago..." takes place immediately after Pike's meeting with Kirk, while The First Adventure depicts a longer voyage. Although they are somewhat contradictory, for ordering purposes, "All Those Years Ago" should take place after the initial chapters of Enterprise: The First Adventure but before the mission shown in the later sections of the book.

Stardate 1278.40
Kirk's first cruise aboard Enterprise was to transport Pike to his next assignment on Draxis II. En route, the Enterprise once again encountered the Tralmanii, a race that Pike had once dealt with before when he commanded the Enterprise. (TOS comic: "All Those Years Ago...")
At Draxis II, the Enterprise delivered medical supplies for the world's colonists. (TOS novel: The Captain's Oath)

Stardate 0000.5
Following the transfer of command from Captain Pike, Kirk expected to be assigned a longer exploration mission. Admiral Kimitake Noguchi ordered Kirk to take the Warp-Speed Classic Vaudeville Company around the Federation Phalanx. The mission proved to be anything but simple, after an encounter with the renegade Klingon, Koronin, and an alien generational ship. (TOS novel: Enterprise: The First Adventure)

Stardate 1297.80
Shortly after Lieutenant Nyota Uhura's assignment to the Enterprise, Captain Kirk and a landing party were taken prisoner by the Klingons. Willing to save her captain and crewmates, Uhura stole a shuttlecraft and eventually rescued the landing party. (TOS comic: "Uhura's Story")
On Kirk's first significant mission after assuming command, the Enterprise was sent to Karabos II to retrieve Starfleet scientists before terraforming comets struck the planet. Kirk's former shipmate Rhenas Sherev and her team recovered irreplaceable information about extinct species in an excavated vault. The Enterprise diverted the comets and helped salvage the Aulacri's heritage. (TOS novel: The Captain's Oath)
Stardate 1305.4
The Enterprise stopped for supplies on Aldebaran III, where Dr. Leonard McCoy took a leave of absence to Starbase 6, and Dr. Elizabeth Dehner and Ensign David Bailey signed aboard. The Enterprise then began a star-mapping mission of Sector Epsilon Z-3, and discovered the mysterious planet Kapeshet. Upon beaming down to Kapeshet, Kirk and his landing party were sent back in time to the 21st century to witness the true first contact between humans and Vulcans. They were subsequently returned to the 23rd century and their memories of the mission were erased. (TOS novel: Strangers from the Sky)
Stardate 1136.2
The Enterprise participated in a first contact with the spider-like Archernarians on Archernar IV. (TOS - Mission's End comic: "Issue 1")

Kirk and Mitchell.

While the Enterprise was on a survey mission to Dimorus, one of the Dimorans attempted to kill Captain Kirk with a poison dart, but the dart was taken by Lieutenant Commander Gary Mitchell. (TOS episode: "Where No Man Has Gone Before" and TOS - My Brother's Keeper novel: Enterprise)

Ship image.

Stardate 1003.6
Mitchell left the ship for over three months to recuperate. During this time, the Enterprise was ordered to intercept an alien spaceship in the Mandylion Rift, which had registered as traveling at warp 15. On arrival in the Rift, they discovered that the Klingons were also expressing an interest. The aliens issue Kirk and Commander Kaul of the Klingons a challenge: one of each their crewmembers have to scale a mountain; whoever wins will receive the knowledge of their technology. Kirk sent Lieutenant Hounslaw Tanaka, but she failed the challenge and fell to her death. (TOS novel: Captain's Peril)


After Gary returned, the Enterprise was redirected from the Muhlari system to Starbase 31, where she took aboard Admiral Ellen Mangione and her team. Mangione then diverted the ship to a planet in the Klingon Neutral Zone, where they were to check on the Klingon renegades, the M'tachtar. The M'tachtar managed to seize control of the Enterprise and headed for Qo'noS. Thankfully, Captain Kirk and his crew, along with the help of Commander Kang, managed to regain control. (TOS - My Brother's Keeper novel: Enterprise)
The Enterprise was summoned to the Noah system by Emperor MacMurray, who demanded to be worshiped as Emperor of the whole galaxy. Kirk was able to negotiate with MacMurray and was appointed Royal High Minister Plenipotentiary for MacMurray, in what became known as the MacMurray Encounter. (TOS novel: The Galactic Whirlpool)

Ship image.

Shortly after, the Enterprise was dispatched to the planet Tendar on a first contact mission, following the Tendarans' movements towards warp drive. Captain Kirk and Lt. Commanders Spock and Gary Mitchell beamed down to meet the Prime Minister, but instead of being greeted, were arrested and sentenced to life imprisonment. Despite attempts to negotiate by Montgomery Scott, in command of the Enterprise, the Tendarans refused, stating that they wanted to make an example out of the prisoners. (TOS comic: "Prisoners")


The Enterprise attempted to save Mestiko from a rogue pulsar, but was only partially successful. (TOS - Mere Anarchy eBook: Things Fall Apart)

The USS Enterprise approaching the galactic barrier.

Stardate 1312.4
In April 2265, Admiral Saylor ordered the Enterprise to the galactic barrier, where they discovered a disaster marker from the SS Valiant. Kirk ordered the Enterprise to probe beyond the barrier, which resulted in the death of nine crewmembers and the creation of god-like abilities in Gary Mitchell and Dr. Dehner. Kirk decided to maroon Mitchell on Delta Vega, but Mitchell was too powerful and a fight broke out. It was thanks to the actions of Dehner that Mitchell was defeated. (TOS episode: "Where No Man Has Gone Before" and TOS - My Brother's Keeper novel: Republic)
It was stated in Constitution that Kirk had been in command of the Enterprise for 13 months.

Ship image.

Stardate 1321.6
The Enterprise headed for Starbase 33 to be debriefed by Admiral Saylor. En route, they entered the Taurus Reach and stopped off at Vanguard (Starbase 47) for repairs. The repairs were rushed so that the Enterprise could investigate the destruction of the USS Bombay and the Starfleet listening post in the Ravanar system. (VAN novel: Harbinger)
After leaving Vanguard, the Enterprise continued on to Starbase 33 and Kirk was debriefed. Following the debriefing, the Enterprise returned to Earth (a journey of ten weeks) to attend the funeral of Gary Mitchell. On Earth, Janice Rand and Dr. McCoy joined the Enterprise crew. (TOS - My Brother's Keeper novels: Constitution, Enterprise)
Harbinger featured Uhura as already being aboard the Enterprise following "Where No Man Has Gone Before", which is at odds with My Brother's Keeper.

While the Enterprise was traveling to Earth for Gary Mitchell's funeral, Captain Kirk tried to compose a letter to Gary's parents. Unable to write the truth about Gary's death, Kirk instead wrote a story about an adventure that Kirk and Mitchell had aboard the Farragut. (TOS comic: "Gary")
While exploring the Sigma Draconis sector, the Enterprise abruptly crashed into a planet composed of a dense liquid that disabled propulsion, shields and weapons. Sigma fishmen encountered the ship and attempted to capture its strange visitors. A freeze gun cannon enveloped the Enterprise in ice to float it to the surface, where deflectors could break the ice and the starship was able to escape the globular planet. (TOS comic: "Nor Any Drop to Drink")
In the Sigma Draconis sector, Kirk and Spock investigated an Eldorian spy ship, only to be abducted by a long distance transporter and forced into a trial by combat on Norus. To rescue them, Montgomery Scott and other officers joined the crew of the Eldorian warship Lebron during its invasion of Norus. (TOS comic: "Menace of the Moloth")
Exploring the Sigma Draconis sector, the Enterprise rescued marooned Thaxians on a junkyard planet. Actually exiled rebels, Captain Kandok and his crew soon took control of the starship. Kirk and Spock warned the homeworld, but rather than assist, Thax aimed nuclear missiles at the Enterprise. Kirk and Spock stormed the bridge, forcing the Thaxians to withdraw and escape in a shuttlecraft. After the shuttle was destroyed by a Thaxian missile, Kirk decided he'd had enough of this sector. (TOS comic: "Planet of Rejects")
An Enterprise probe studying Palnak's planet drew the attention of Palnak in the 33rd century, and he used time travel to bring the probe, Kirk and Spock into the future, where he tried to preserve them as exhibits in his museum. Their disappearance prompted Scotty to launch two rescue shuttlecraft, which were also brought forward in time, but Kirk and Spock were able to escape, and Spock set the temporal equipment to return them all to their original time. (TOS comic: "The Ageless One")
As Kirk and Spock beamed down to Santar, synchronous solar flares of Salgorax and Neptor disrupted the Enterprise's transporter, and they rematerialized on the planet Muton in an adjacent system amidst an invasion by frogmen. They helped a band of Muton native rebels repair their crashed spacecraft, and in return were given a transport to return to the Salgorax-Neptor system. (TOS comic: "Slaves of the Frogmen")
The Enterprise monitored a probe on Nova XIII launched by the Trans-Galactic Zoological Federation. When telemetry abruptly ceased, Kirk and Scott took a shuttle to investigate. They were captured by natives and brought before a government council. With their universal translator damaged, they were unable to communicate. Concerned that they were going to be executed, they escaped and returned to the Enterprise, unable to recover the probe. (TOS comic: "Nova-Thirteen")
Near the Perseant Alpha system, a temporal disruption sent the Enterprise 400 years into the past. The crew found themselves in orbit of Zeltok two weeks prior to its destruction. A shuttle team explored the surface, discovering Karn, the last surviving Zeltok, as well as sentient races of ants and gorillas. Karn refused to be rescued, and a subsequent astral storm returned the Enterprise to the 23rd century. (TOS comic: "Vibrations in Time")
Starfleet ordered the Enterprise to investigate suspicious military activity on Korak. Zodians attacked the starship, then quickly surrendered. They confessed that capture was the only way they thought they could escape from the dangerous planet. An Enterprise shuttle was wrecked by a dinosaur, and the Zodians gave their lives to save the shuttle. (TOS comic: "The Zodian Sacrifice")
Stardate 1026.3
While surveying the supposedly uninhabited Gamma Alpha V, the Enterprise discovered a city populated by android duplicates of historical figures, including George Washington. Spock was abducted by Alexander Lazarus, the androids' creator, but escaped just prior to the planet's destruction. (TOS comic: "The Legacy of Lazarus")
Stardate 1126.1
The Enterprise went to Pollux II to investigate the disappearance of several spaceships in the vicinity. They discovered that the people were being captured by Malok so that he could stimulate emotional responses in them and then absorb the emotions into himself. Malok was defeated when he absorbed emotional Vulcan minds that the Enterprise had intended to transport to Beta IV. (TOS comic: "The Brain Shockers")
Stardate 1248.6
En route through Sector Vega 6 to a rendezvous with Ambassador Mason at Starbase 10, the Enterprise was captured by Chang, a self-proclaimed sorcerer, who threatened to destroy the ship unless Kirk and Spock obtained for him a magical sceptre. After finding the sceptre, they discovered that the quest was merely a ruse to distract them while Chang seized control of the Enterprise, and defeated him. (TOS comic: "Sceptre of the Sun")
Stardate 1483.4
The Traveler hijacked the Enterprise to take him to his homeworld, only to find it in ruins and his people conquered by his brother Niklon. He and an Enterprise landing party overthrew his brother and freed his people. (TOS comic: "Dark Traveler")
Spock was attacked by a huge dinosaur during his survey of Dukar. Atmospheric interference blocked the transporter, and he was forced to kill the animal. During this incident, Queen Lok of the planet Neesan received an empathic impression of the incident and believed it to be an image of her god, Unruho. (TOS comic: "The Cosmic Cavemen")
During their watch on Orthoo, Enterprise security guards lost the Great Eye of Ara, a holy relic. Kirk paid King Yo a fortune in credits for compensatory damages. Unknown to him, guard Red Garvin had stolen the artifact, and it was later recovered. (TOS comic: "Furlough to Fury")


The Enterprise shaken by a cosmic storm

Stardate 20:0605

Medical personnel rescued an escape pod but couldn't save its pilot from a deadly infection, discovering that his people on Zargot were suffering from a plague. A cure was believed possible using herbs from a neighboring planet, so Captain Kirk took a shuttlecrawler to the surface of Coltac. While harvesting the herbs, they repelled two large dinosaurs with phaser fire. Doctor Leonard McCoy and Ixta succeeded in making an antidote. (TOS comic: "Target: Zargot")

Stardate 20:16.45

Infectious pollen on Crucial III incited Hurst's landing party to mutiny, exiling Kirk and McCoy in the damaged Space Bug 7. They made a rough landing on Vultra, where military leader Zella warned of an extinction-level crisis, but rather than ask for help, he and his science advisor commandeered the space wagon and fled the planet. The Enterprise's first officer, Commander Spock, cured the mutineers with an antitoxin, and Hurst immediately set out to rescue Kirk and McCoy. Before leaving, Kirk provided the Vultrans with engine modifications to create viable starships out of existing spaceships so their civilization could find a new homeworld. (TOS comic: "The Crucial Element")
Stardate 24.09.45 - 25.00.10
This period saw the Enterprise hit by a cosmic storm generated by a supernova; the starship rode out the storm without incident, but after Spock noticed a problem with the star camera and had the ship's repair wagons launched to conduct repairs. Jackson, aboard one of the wagons, noticed the Enterprise had entered orbit of a planet which the Enterprise's computers had not detected. Captain Kirk ordered the wagons back aboard and the ship's computers disconnected to try and fix their problems, but as the crew attempted to carry out the order they found the computer resisting, and received a message commanding them to stop. The Enterprise was then remotely piloted in to land on the planet's surface.

The Enterprise landed on the Robots' planet's surface

Once the Enterprise had landed the native Robots who had taken control of the ship demanded the crew disembark and then neutralized them with their energy weapons. Some of the Enterprise crew were later able to escape, but were then found by the Robots again, who demanded Captain Kirk and Mr. Spock comply in removing a power rod from the Enterprise to help resupply the Robots' own dwindling energy supplies, or risk the Robots harming the rest of the crew.
Kirk agreed, but also plotted against the Robots, using a cobalt container to transport the power rod once it was removed from the Enterprise's power unit. The combination of power rod and cobalt container created an explosive devise which would react fifteen minutes after its creation. Not quite as planned, but to the same eventual outcome, Kirk was able to get the sabotaged power rod to the Robots' power unit, causing it to explode and making the Robots shut down, allowing the Enterprise to depart. (TOS comic: "Life Form Nonexistent")

Stardate 24:12.17

While exploring a new region of space, a starship resembling a huge, living eagle attacked the Enterprise. After disabling the strange vessel, David Bailey and others visited in a space bug to offer assistance, discovering what appeared to be a group of humanoid refugees kidnapped by Agonites. Kirk and Spock recovered the humanoids and resettled them on nearby class M planet, leaving them with provisions and weapons. Shortly afterward, however, a dozen of the space eagles arrived, and Kirk learned from Roggaf of Agoni that they were galactic police officers, and the "refugees" were actually convicted criminals. To make up for his interference, Kirk recaptured the criminals and turned them over to the Agonites. (TOS comic: "The Eagles Have Landed")
Kirk led a diplomatic mission to Angoma, where citizens have been mysteriously disappearing. The culprit: a long distance transporter, which trapped Kirk's team in a Mantis zoo. Bailey tracked the beam's path, leading the Enterprise to the Mantis planet. Spock led a search party, but Kirk's team had already used the transporter to escape to another world. Spock's team followed, rescuing them from cannibals. (TOS comic: "Beware the Beast")
While exploring the Hytar Nuofo system, the Enterprise was assaulted by Hytaran spaceships whose commander said he thought they were enemy Nuofons. Kirk attempted to visit Nuofo as a mediator, but his exploration rocket was shot down and his landing party apprehended. When more ships attacked, Kirk launched an all-out assault on Nuofo, which surrendered. Peace was short-lived, however, when Nuofo's city was suddenly struck by missiles from a mutual enemy, Desta. After the Enterprise drove off a Destan fleet, both governments held democratic elections and were reunited under new President Juf. (TOS comic: "The Third Party")

Stardate 25:11.23

During a diplomatic visit to Galactic Union world Stai, everything went well until Union Officer Ruf forced Kirk to leave by threatening the lives of Da Nek's son and other children housed on neighboring planet Vrex. Angered by Ruf's bullying tactics, Kirk sent a landing party and four shuttles to Vrex to retrieve the kids, but his crewmen were captured and Kirk was placed in a brainwashing machine. An armed rescue team recovered the crew, and Spock was able to reverse the brainwashing. After the children were brought home, the Staians formally quit the Union. (TOS comic: "The Children of Stai")

Stardate 48 12.46

The Enterprise was caught within a self-sealing oxygenless gas cloud around a mysterious planet. A contingent of warlike, non-humanoid Balants attempted to commandeer the Enterprise to escape their homeworld. Kirk and Spock beamed down in environmental suits to visit an underground city, where they learned about the Balants from their cousins the Kalins. Meanwhile, the Balant leader broke through an airlock onto the Enterprise, but oxygen exposure vaporized him. Kirk explained to the remaining Balants that they could not survive without their protective gas cloud and must learn to live with the Kalins. (TOS comic: "Skin Deep")
Stardate 1512.2
The Enterprise made first contact with Balok, commander of the Fesarius, representative of the First Federation. David Bailey transferred to the Fesarius as an exchange officer. (TOS episode & Star Trek 12 novelization: The Corbomite Maneuver)

Ship image.

After being promoted to helmsman, Hikaru Sulu led his first landing party on an uncharted world that held archaeological ruins. A member of Sulu's team accidentally triggered an ancient security system and geologist Vanani Manprasad was killed. Sulu confided with friend and shipmate Janice Rand about his self-doubt as to whether or not he was truly bridge officer material. Sulu got over his doubts after Kirk cleared him of all wrong-doing in the matter and assured him that the Helm was still his if he wanted it. (TOS short story: "The Landing Party")

Harry Mudd's cargo.

Stardate 1329.8
While on patrol, the Enterprise rescued four survivors from a damaged freighter. One of the survivors was discovered to be con man Harry Mudd, while the others were three "beautiful" women. It was thanks to the efforts of Mudd and his women that the Enterprise obtained replacement lithium crystals from Rigel XII. (TOS episode & Mudd's Angels novelization: Mudd's Women)
Stardate 1672.1
An unusual ore on Alfa 177 caused a transporter malfunction, splitting Kirk into good and evil versions. While the transporter was under repair, Sulu's landing party suffered as temperatures plummeted. Spock and Montgomery Scott successfully re-integrated Kirk's two halves, and the landing party was beamed up, saving them from freezing to death. (TOS episode & Star Trek 8 novelization: The Enemy Within)
Stardate 1513.1
On a routing medical resupply mission to M-113, it was discovered that Professor Robert Crater's wife Nancy had been murdered by an M-113 creature who assumed her identity. Several crewmen were killed by the creature before it was located and destroyed. (TOS episode: "The Man Trap", TOS - Star Trek 1 novelization: The Unreal McCoy)
Stardate 1704.2
On collapsing planet Psi 2000, an Enterprise landing party was infected by the Psi 2000 virus. As it spread quickly throughout the crew, Kevin Riley shut down the warp engines, stranding the Enterprise in a decaying orbit. Scott initiated a cold-start of the warp drive, triggering a breakaway that threw the starship out of orbit and three days into the past. (TOS episode & Star Trek 1 novelization: The Naked Time)
Stardate 1704.2
En route to Psi 2000, the Enterprise left a large survey team on the surface of Tlaoli IV. Following the incident at Psi 2000, resulting in the Enterprise being flung back in time three days, the Enterprise returned to Tlaoli early. On arrival back at the planet, they discover that half of the team had disappeared. Captain Kirk led a cave expedition team and found his team, but both he and Lieutenant Sulu were transposed in time, by a Jim Kirk from 2247, and Captain Sulu from an alternate 2287. The situation was later resolved by traveling into the various timeframes and restoring the natural course of events. (TOS - The Janus Gate novels: Present Tense, Future Imperfect, Past Prologue)
The Janus Gate trilogy became an alternate reality upon itself because it occurred in the three day pocket of time, leaving the characters with no memory of the events afterwards.
An atmospheric storm disrupted the transporter, scattering the ship's landing party on a desert planet. Nyota Uhura was stranded in a desert and forced to wait for the storm to pass before Scott could beam her back. She waited in an oasis and bonded with a strange creature, singing to it in Swahili. (TOS - Waypoint short story: "Daylily")
Stardate 1533.6
The USS Antares transferred refugee Charlie Evans to the Enterprise, but the 17-year-old boy had been imbued with psychokinetic powers by Thasians and was unable to live safely with others. (TOS episode & Star Trek 1 novelization: Charlie X)
Stardate 1699.0
The Enterprise was summoned to the Federation colony on Alpha Proxima II to deal with a viral epidemic, along with the USS Constellation. While Captain Kirk and Commodore Matthew Decker strived to keep the planet running, Dr. McCoy and Dr. Lewis Rosenhaus struggled to find a cure, and eventually succeeded. The cause of the virus was later revealed to be from a Malkus Artifact that was unleashed by Tomasina Laubenthal, chief of police on the colony. (TOS - The Brave and the Bold, Book One novella: The First Artifact)

Stardate 17:01.02

After shore leave on resort world Lado, the Enterprise entered a subspace parallel universe in quadrant Mark 1, discovering a stasis chamber containing the James T. Kirk from the previous Big Bang cycle of the universe. Kirk's predecessor demanded a fencing duel with the current Kirk in order to create a turning point in predestination. Aiding him was a USS Enterprise decoy replica that shot at the Enterprise during the duel. When Kirk refused to kill his predecessor, it created the moment of free will, and the predecessor faded from existence. (TOS comic: "The Choice")
Stardate 1709.2
A reluctant Keras commanded the Romulan bird-of-prey ChR Gal Gath'thong in its attempt to incite war with the Federation by destroying Outpost 4 and other Earth Outpost Stations located along the Federation side of the Romulan Neutral Zone. The Enterprise engaged and destroyed the invading vessel. (TOS episode & Star Trek 1 novelization: Balance of Terror)
Kirk, Spock and Scott made first contact with the felinoid Skurians, but Scott offended supreme head Zeldon, who responded by locking the officers in a zoo with humanoid cavemen. During their jailbreak, Kirk saved Ambassador Meng's life. In gratitude, Meng had them officially freed and returned their communicator, hoping that one day their species might understand each other. (TOS comic: "Captives in Space")
Enterprise crew set up a small expeditionary team on Selkye led by Professor Richard Spellman. McCoy became enamored with cute, little beavos on the planet and kept one as a pet. McCoy soon became sick and weak, while a corpse recovered from the surface suddenly reanimated. Events repeated the next day after Uhura cared for the beavo. The Enterprise returned to Selkye, rescuing the science team from a group of Selkye toad humanoids. The parasitic beavos had drained life energy from the scientists and transferred it to the corpses. (TOS comic: "Planet of the Dead")
An expanding Taragon colony suddenly faced spontaneous bursts of insanity among the colonists, as well as volcanic eruptions and other natural disasters. The Enterprise responded to their distress calls and investigated. Kirk and Spock suspected intelligent lifeforms capable of telepathy might be responsible, eventually discovering a massive, non-humanoid Taragon lifeform living underground that was able to replicate objects and people. Frightened of the encroaching colony, it had tried to make everyone leave. In exchange for its protection, it agreed to help fashion new buildings and equipment for the colonists. (TOS comic: "What Is This Thing Called Spock?")
Uhura picked up lifeform sounds near a volcano that was due to erupt imminently on planet Alpha 332. Kirk and Spock beamed down to help, finding a group of Parraca praying to the volcano. Kirk and Spock effected an evacuation, but the two were then captured by a group of ape-like Turracas on the other side of the volcano. They would not heed similar warnings, and Kirk and Spock beamed up before they could be sacrificed to the volcano. (TOS comic: "The Gods Have Come!")
The Enterprise responded to frantic distress calls from Ynobe II, where they found the planet being terrorized by trillig robots. Kirk, Spock and Scott shut down the robot factory and apprehended the person responsible, restoring peace on the world. (TOS novella: Trillions of Trilligs)
Stardate 7000
The Enterprise visited Ecnal, which was beset by an unexplained planet-wide loss of life energy. Kirk, Spock, McCoy and Janice Rand explored the surface, discovering the culprit: an alien Lerow rocket stealing the life energy. The landing party learned that the Lerows were acting out of desperation to restore their dying homeworld. The Lerows were given an energy converter and they departed gratefully. (TOS comic: "Planet Ecnal's Dilemma")
Kirk and Spock were gassed while visiting Raylo, leaving Kirk hypnotized. Spock and McCoy followed Kirk through a cave where he climbed into a stasis chamber. The device began draining his electrical energy for Doctor Rycho, who used the energy to power Mortard robots. Spock theorized that communicators could disrupt stasis. When Kirk answered Spock's hail, the equipment shorted out, Kirk broke free, and Rycho was apprehended. (TOS comic: "Rescue at Raylo")
On previously uncharted Noriga, Kirk and Spock signed a treaty with the natives, who were a humanoid race of varying heights. When Kirk and Spock beamed back to the Enterprise, however, they found they'd had mysteriously shrunk like the Norigans. Quickly returning, they learned that a mutagen purposefully launched into the atmosphere shrank people to a size inversely proportional to their age. Kirk and Spock grew back to normal after a few days. (TOS comic: "The Unchartered World")

Stardate 17:23.4

Following a mission on Kynardi, the Enterprise discovered that the inhabitants of Argylus suffered from an epidemic that killed anyone who reached 13 years of age, a disease that infected the landing party. The starship hastily traveled to Ominnus in order for the crew to retrieve herbs needed to synthesize a cure. (TOS comic: "Child's Play")

Stardate 18:06.9

In the Sol system, the Enterprise recovered the stasis chamber of Alfred Bleikoff, a noted pacifist cryogenically frozen in the 1990s. Unknown to the crew, Bleikoff's brain had been surgically replaced with a mechanical one during the intervening years, presumably to prepare Earth for an invasion. Kirk, Spock, McCoy and Scott received an electrical jolt while reviving Bleikoff which immunized them from Bleikoff. Bleikoff campaigned on Earth for peace, using powers of mass hypnosis to sway large sections of the population to deactivate the Earth's planetary defense system. Before a vote could be taken, Kirk was able to deactivate Bleikoff. (TOS comic: "Prophet of Peace")

Stardate 18:09.2

The Enterprise explored the planet K-G. Unfortunately, the planet was home to a plant species that threatened the galaxy. Capt. Kirk was forced to exterminate all plant life on the planet, as it bore too great of a threat to the rest of the galaxy. (TOS comic: "The Planet of No Return")
A Klingon scientist at a military research outpost developed a weapon of mass destruction with limitless range capable of destroying a planet. He tested it by luring the Enterprise to Seggor, then using his experimental granulator cannon on Crewman Hoskins, who collapsed to dust after being touched by Kirk. As a further demonstration, the weapon destroyed Kirk's shuttle through its shields. Kirk retreated, prepared to send a message that Earth must surrender to avoid destruction. Scott disobeyed orders and beamed down to Seggor, where he sneaked into the base and sabotaged the cannon's blast hatch. When fired at the Enterprise, the weapon overloaded and destroyed the base. (TOS comic: "The Klingon Ultimatum")
During Kirk and Spock's diplomatic meeting with officials on Fornia, the planet was bombarded from orbit and then invaded. As troops spread out, Klingon Commander Tharrk demanded surrender to prevent further devastation. Kirk and Spock hid, then devised a strategy to take out the Klingon battle cruiser by tricking its crew to fire on a mirrored satellite, which reflected the beam back and caused heavy damage to the cruiser. Kirk and Spock subdued Tharrk and promised that future aggression would be defended by the Federation. (TOS comic: "Smoke and Mirrors")
Stardate 1831.5
While the Enterprise transported medical supplies to Beta Carinae, Lt. Commander Spock and Lieutenant Sulu were charged with transporting Prince Vikram back to his homeworld, Angira. (TOS novel: Shadow Lord)

Stardate 18:41.2

The Enterprise beamed down a survey expedition after large deposits of valuable ores were detected on Beta II. In fact, the mineral deposits had been faked by Klingons to lure the Enterprise there and replace Captain James T. Kirk with a duplicate. The Enterprise left Beta II after being ordered to escort Omegan ambassador T'Ki home, but returned in pursuit of the duplicate Kirk, who had fled after the crew mutinied against him. Back on Beta II, Spock exposed the Klingon plot and rescued the real Kirk. (TOS comic: "The Enterprise Mutiny")

Stardate 19:03.4

The Enterprise came across a strange belt of uncharted asteroids near the Nabu system. The Enterprise was then caught in a electronic field shielding the planet. Capt. Kirk then led a landing party to investigate. The planet was revealed to be a penal colony that would blow at some point. Kirk and the Enterprise were then able to escape before the planet exploded. (TOS comic: "The Devil's Isle of Space")

Stardate 19:24.3

On Neesan, Kirk, Scott and McCoy discovered Tol tribesmen worshipping a stone idol of Spock, made from an image their telepathic leader Lok-the-Wise had seen in a vision. The landing party was about to be executed for trespassing on scared ground when Spock materialized in front of the tribe, instantly being hailed as spiritual leader Unruho. An invading tribe of Kovars overran the land, destroyed the statue and prepared to kill Kirk and Scott. Spock used the transporter to appear and disappear, convincing many of the Kovars that he was Unruho, and prompting the Tols and Kovars to pledge going forward in peace. (TOS comic: "The Cosmic Cavemen")

Stardate 19:24.8

While exploring Kujal, Kirk, Spock and Uhura were captured by Kujalans, humanoid colonists who had been shrinking for three generations due to strange stellar radiation. After learning of their history, they offered to find a solution to their problem.
