Spirk is the slash ship between James T. Kirk and Spock from the Star Trek fandom.


Season 1


102 Spirk

Kirk and Spock beam down to M-113 to speak with Professor Crater. They find him among the ruins and yells that he wants them to leave. As Kirk tries to calm him down, Spock wanders and finds the body of Ensign Green. He calls Kirk over and Kirk points out that he beamed onto the ship with them. Spock says that something did and Kirk orders that Enterprise on lock-down. Spock says that they can take Carter with them to find out about the creature, and Kirk agrees. They're suddenly knocked over by a laser and have to take cover from Crater. Spock says that taking him will be difficult, and Kirk tells him that he'll be setting his phaser on stun. Spock says that Kirk will be risking his life for Crater's, but Kirk says that he's only trying to frighten them. Spock points out a way for them to sneak around and they set their plan in motion.

As they try to get the drop on Crater, Spock calls Kirk and Kirk gives him the signal to distract him. Kirk is able to stun him and they both rush to him. Kirk asks where Nancy is, and Crater explains that the last creature on the planet came to them and killed Nancy, then ended up taking her place. Kirk calls the Enterprise and has the three of them beamed out.

Kirk gets a call to the infirmary and rushes down to find Spock injured. Spock tells him that the creature took the form of McCoy and attacked him. They find Crater dead in the next room, and Kirk asks how Spock ended up okay. Spock was just lucky that he's a Vulcan, and has a different genetic make up.

The creature ends up trapping Kirk in McCoy's quarters, just as Spock arrives. Spock tells McCoy to shoot it, since it's killing Kirk, and when he fails to do so, puts himself between Kirk and the creature.


Kirk is distracted while he and Spock play 3D chess, which Spock points out. Kirk's mind is on the Antares, and can't comprehend what happened. Spock expresses his own concerns, but over Charlie. Kirk is confused, and Spock says that he seemed to know what happened to the Antares before anyone else. Charlie then walks in, and Kirk thinks it's a pretty long reach for evidence. They continue their game and Kirk reaches a checkmate. Spock laments that Kirk's illogical approach does have advantages, and Kirk prefers to call in inspired. Spock lets him, and says that the game is his. Kirk asks if Charlie has ever played, and Charlie admits that he hasn't and asks to try. Kirk leaves him in Spock's hands as he leaves.

Kirk and Spock rush to Rand's quarters to rescue her from Charlie, when they are thrown against the wall by Charlie. After Charlie makes Rand disappear, he lets Kirk go for a moment. As Kirk stands he asks Spock how he is. Spock says that his legs are broken, and Kirk angrily tells Charlie to let Spock go. Charlie asks why he should and Kirk says that he needs Spock to help run the ship. Charlie then lets Spock go and storms out.


In the briefing lounge, Captain James T. Kirk and Vulcan science officer Lieutenant Commander Spock are playing three-dimensional chess. Spock warns the captain that he's about to checkmate him on his next move, but the captain is preoccupied with awaiting the bridge's update on the unexplained Earth-vessel distress signal. Kirk notes how Spock plays an irritating game of chess, Spock replies that he wouldn't know the meaning of the word since it's an earth emotion. Kirk makes a surprising move and asks if he really doesn't know the meaning of irritation. Spock says that just because he has a human ancestor doesn't mean he has emotions, but Kirk interrupts him asking about having bad blood. The two receive a call from the transportation room and they head there.

After the Enterprise is attacked by an unknown force, that had attacked the Valiant as well, Kirk supervises repairs on the bridge. He see's Spock looking over medical records of dead crew members. He then see's Spock monitoring Gary Mitchell over the monitor.

After a meeting discussing what to do about Gary, Kirk and Spock are the only one's left in the briefing room. Spock suggests they repair the ship at Delta Vegaas well as strand Gary there. Kirk is against the ideam but Spock tells him that the only other option is likely going to end with Kirk killing Gary before he kills the crew. Kirk is against this as well since Gary is his friends, but Spock tells Kirk that the Captain of the Valiant had most likely faced a similar decision. Kirk then orders the ship to head for Delta Vega.

On Delta Vega, Kirk and Spock keep an eye on Gary as the crew gathers supplies and repairs the ship. Kirk doesn't like how cold Spock is towards Gary. But Spock just believes he is being logical, since it's most likely that the crew will only barely get the repairs done before Gary awakens. Kirk understands.

Gary wakes up and escapes hurting Spock in the process. Kirk blames himself for Spock getting hurt and finally understands that he has to kill Gary. He tells the Doctor to take Spock to take him back to the Enterprise as he confronts Gary.

After Gary is killed Kirk sits in the Captain's chair, as a recovered Spock enters the bridge. Kirk tells him he wants Gary's record to be clean, since what happened to him wasn't his fault. Spock understands and that he felt for Gary as well. Kirk smirks telling Spock that there's hope for him after all.

Season 2


Overhearing Kirk's conversation with Scotty, Spock says that he finds the situation with the Enterprise unusual. Kirk thinks that Scotty can handle it and asks if Spock found anything with the Tricorder. Spock tells him that he found vibrations that are artificially made, and Kirk send some of security team to survey the area. Spock notices something and Kirk asks what it is. Spock tells him that there is someone following them, and Kirk takes a security member to find them.

Spock suggests that the Enterprise's could probably have to do with the vibrations he read earlier. Kirk suggests a generator and Spock says that it would have to be immense and subterranean. Kirk notices McCoy examining something and goes to join him. Spock then notices the same flower that killed Hendorff before. He yells to Kirk and pushes him out of the way getting hit with the thorns himself. Kirk runs to Spock's side as he collapses, and McCoy starts to try and wake him again. Kirk asks if he's alive, but McCoy says that they need to get him back to the ship. Kirk then calls Scotty to beam them up, but there is something wrong and they're unable to do so.

Spock then awakens and Kirk runs to him to ask how he is. Spock says that he is fine, but is annoyed by McCoy's treatments. Kirk asks what he was trying to do, and Spock explains that he though Kirk was unaware of the plant so he- Kirk interrupts and says that he stepped in front and took the thorns himself. Spock says that it wasn't his intention, that his own clumsiness stopped him from moving away from the thorns. Kirk tells him to just yell next time, he can move as quickly as anyone else. Spock promises to do so. Kirk can't believe that he would try and get himself killed, and asks if Spock knows how much Starfleet invested in him. Spock starts to answer, but Kirk says never mind. He does thank him though, and sends security around the perimeter.

As Kirk laments over the death of his crew members, Spock follows him and says that the deaths were unavoidable. Kirk says that he could have prevented it, but Spock doesn't see how. Kirk believes that they should have beamed up at the first sign of trouble, but Spock reminds him that they were under orders to investigate the planet. Kirk reminds him that he can disregard orders if they're overly hazardous. Kirk doesn't think that this mission was worth three of his men, or his ship, and that he let his guard down. Spock reminds him that Starfleet duty isn't safe, and Kirk did everything a commander would do. He starts to tell Kirk that blaming himself won't help, when he hears the same person from before following them again.

They are taken to Vaal by the figure known as Akuta. Spock does some readings and finds that it generates a great amount of power. Kirk asks if the it's the center of power, but Spock says that farther below the surface. He starts to walk towards it but then is flown back by a force field. Kirk goes to him and asks if he's alright, Spock says that he is and Kirk helps him stand up.

The away team notices the villagers leaving the village, and Kirk asks Spock to follow them as they watch. They watch the villagers "feed" Vaal, and Spock believes that their initial idea was right. That Vaal is no more than a computer. Kirk suggests going in since the field is down, when Vaal's eyes light and the planet starts to shake. The two decide that it's not the way to go, and Spock suggests that the machine might be intelligent. Kirk says that it still needs to "eat" so it can't have that much power. Spock says that it doesn't help much, given that they only have 10 hours to get the Enterprise out of there. Kirk suggests that Vaal is weaker around feeding time and asks Spock to contact the ship to find out how much power they're expending.

That night, Spock tells Kirk that the village isn't ideal, but it is viable. Kirk thinks that McCoy was right, that the people are existing and not living. Spock says that if they destroy the Vaal, then it would be a violation of the noninterference directive, but Kirk says that they're people and should have the opportunity to choose. They owe it to interfere, but Spock points out that Starfleet would think otherwise. Kirk says that he'll take his chances and tells Spock to have a look around. Spock quickly returns and tells Kirk that all the villagers have disappeared.

As the Kirk attempts to contact Vaal, lightning starts to storm overhead. He and Spock attempt to run away but Spock is struck by lightning and goes unconscious. Kirk then carries him back to the village. He calls for McCoy and places Spock down and he comes to consciousness. McCoy tells him that it's not serious as the villagers return and attack them.

Kirk gets an idea and has Spock follow him to Vaal. He calls Scotty to fire on Vaal when he gives the order. Spock reads that Vaal is getting weaker and Kirk says that pulling the Enterprise away must have done so. Spock theorizes that firing on it would cause it to weaken further and eventually run out of power, which Kirk was planning on. He calls Scotty to fire and he does so. Spock reads that Vaal is trying to reinforce the field and Kirk wants to see how long he can hold out. As Vaal explodes, he tells Scotty to cease fire and Spock reads that the power is gone. Vaal is dead.

Kirk is walking down the halls of the Enterprise when McCoy calls him over to him and Spock. Spock says that he doesn't think they did the right thing on the planet, but McCoy insists that they did. Kirk sees it as a lesson on what happens when the machines do to much for them, and Spock asks if Kirk is familiar with the story of Adam and Eve. Kirk is and Spock suggests in such an analogy, they have given the people "the apple" and have driven them out of paradise. Kirk sarcastically asks if he's casting him in the role of Satan, and Spock starts to say he isn't when Kirk asks if there's anyone on the ship who even remotely looks like Satan, as he and McCoy circle Spock. Spock realizes they're referring to him and says that he doesn't. Kirk didn't think that he would and walks off with McCoy.


As they knock out the mobsters, Kirk tells Spock and McCoy to get to the radio station, so that they can call Uhura and can get themselves beemed up. Spock says that Kirk has to come, and Kirk says that he will. He just needs to grab Okmyx first. The three then separate.

As Okmyx tries to keep Spock and McCoy, Kirk shows up and threatens his goons. The mobsters are backed into a corner as Kirk asks Spock that he thought he was supposed to return to the ship. Spock says that they did, but Kirk getting kidnapped required them to return. Kirk's thinks that might be fore the best and asks if he figured out anything from the computer. Spock didn't find anything, as logic doesn't seem to apply here and Kirk asks if a hunch is okay. Spock's not a fan, but he doesn't see an alternative. Kirk then has two of the mobsters switch clothes with him and Spock.

They exit the building and hop into the car outside, but they're both unable to drive it. Spock explains the parts of the car and Kirk is able to drive it, although not very well. Once they arrive at Kracko's, Spock says that Kirk is an excellent Captain, but not a very good driver. Kirk asks if it was that bad, and Spock confirms so. They hop out of the car and Kirk notices the guards, but doesn't think they'll be able to stun them out in public. Spock suggests getting close when a boy runs up and asks if they're putting a hit on Kracko. He tells them that he can fix the problem, which Spock objects to, but Kirk wants to hear him out. They strike a deal and the kid is able to get close to the guards and so that Kirk and Spock knock them out easily.

They enter but are quickly captured by Kracko. Kirk is able to get Kracko alone and starts to play up the part of a gangster, getting Spock to follow along. He tells them that the Federation is taking over and walks over to the desk. He sits down and tells Spock to sit down with him. Spock joins and mimics him as Kirk places his feet on the desk.

As they exit the building, Kirk runs to the car but Spock momentarily stops him. He asks if they must and Kirk says that it's faster than walking. Spock says it's not as safe and Kirk asks if he's afraid of cars. Spock insists that he isn't, but Kirk's driving does. Kirk insists that he has the hang of it and tells Spock to get in. They then drive off back to Okmyx's.

Kirk comes up to Spock and McCoy and says that they have been brooding since they left the planet. Spock says that he hasn't but does have reservations over the way they left the Ionians. Kirk summizes that Spock doesn't think it's a good idea to leave criminals in charge, and Spock confirms as wells as expressing concerns over how Kirk plans to explain the results to Starfleet. Kirk comes up with his own idea, but Spock doesn't find it all together, very logical.


As everyone on the bridge waits for Spock's analysis of the debris Spock tells Kirk that it is what's left of the SS Beagle. He finds no signs of bodies, and Kirk concludes that there's a chance that the crew survived. He asks Spock to trace back where the debris likely came from, and Spock does so. As they head towards the planet, Spock points out that he believes Kirk knew the captain of the Beagle. R. M. Merik. Kirk confirms this as they reach the planet, which is strikingly similar to earth. Kirk asks what era, and Spock says it's pre-warp. A program from the planet is placed on screen and it shows that the planet is a mix of the 20th century and old Rome. Spock says that one of the men on screen was the first officer of the Beagle and Kirk tells him to ready the transporter room.


Kirk asks Spock what he makes of the cat, and Spock says that it's an interesting creature. He feels rather drawn to it. Kirk gives him a smile and asks the rest of the crew for anything they can find on their guest, but no one can find anything. He asks Spock for a historical report and Spock tells him all the he can, including war heads being launched on that day. Kirk asks if warheads were the biggest problem of the era and Spock confirms so.

Behind the Scenes

Marshak and Culbreath“There's a great deal of writing in the Star Trek movement now which compares the relationship between Alexander and Hephaistion to the relationship between Kirk and Spock -- focusing on the closeness of the friendship, the feeling that they would die for one another --”
Roddenberry“Yes, there's certainly some of that, certainly with love overtones. Deep love. The only difference being, the Greek ideal ... we never suggested in the series ... physical love between the two. But it's the ... we certainly had the feeling that the affection was sufficient for that, if that were the particular style of the 23rd century." (He looks thoughtful.) "That's very interesting. I never thought of that before.”
Where No Man ... The Authorized Biography of William Shatner
ET“You don't mention Captain Kirk by name, but you drop several Easter eggs alluding to the future Enterprise captain. In Michael and Spock's final goodbye, Michael advises him to find his "opposite," who can guide him. Can you confirm that's Kirk you're alluding to?”
Michelle Paradise“Absolutely. That is definitely Kirk.”

Spock/Kirk is considered to be the first ever fan fiction pairing, at the very least the first to be documented and to reach a wider audience. While other pairings such as Napollya were also created at the time, they didn't have the same staying power as K/S.

After the reboot fanfiction writers would take situations and moments from the original timeline and re-write them in the style of the reboot.

September 15th is considered "Spirk Day" as it's the anniversary date of when Amok Time aired. One of the episode's most often cited for shipping Spirk.

On AO3, Spirk is the most written ship for both Kirk and Spock. It is also the most written relationship in the Star Trek, Star Trek: The Original Series, Star Trek: The Original Series (Movies) and the Star Trek: The Alternate Original Series tags, the second most written in the Star Trek: The Next Generations (Movies) tag and the ninth most written in the Star Trek: The Next Generation tag.

  • Many consider Spock/Kirk to be the first ever slash pairing and Star Trek the first time we see the start of modern fandom.
  • K/S was the first 'ship' that got widely popular and accepted. It's one of the most important pairings in the shipping history.
  • In a parody episode of Legends of Tomorrow, Ava and Sara are made into versions of Spock and Kirk and end their episode with a kiss[2].
