Back story Born in the 23rd century (human time) of
Sarek (
vulcan) and
Amanda Grayson (human), his mixed heritage was cause of a troubled childhood. Pure vulcan children repeatedly bullied him on
their home world (Vulcan) to incite his human emotions. For a time, he grew up alongside his older half-brother Sybok, until Sybok was cast out from Vulcan for rejecting logic. Spock has a human adoptive sister,
Michael Burnham . Spock was betrothed to T'Pring during his childhood. Sarek supported Spock's scientific learning and application to the Vulcan Science Academy. . Spock rejects his acceptance into the Vulcan Science Academy on the basis that they would never fully accept someone who was only half-Vulcan. Because Spock did not enter the VSA and sought to join
Starfleet instead, he did not speak to his father for the following 18 years. Spock also appeared in the second pilot, "
Where No Man Has Gone Before", which was broadcast initially as the third episode. During the events of that pilot, Spock became concerned at the risk to the ship posed by Lieutenant Commander Gary Mitchell (
Gary Lockwood) and suggested possible solutions to Captain
James T. Kirk (
William Shatner). The earliest appearance of Spock in the series as broadcast was in "
The Man Trap". When he needs to knock out an evil version of Kirk in "
The Enemy Within", he uses a
Vulcan nerve pinch, marking the first appearance of that iconic move. Spock and Chief Engineer
Montgomery "Scotty" Scott (
James Doohan) work together to rejoin the good and evil versions of the Captain, which had been split following a
transporter accident. During "
Miri", he finds himself to be the only member of the landing party to be immune to the physical effects of the disease affecting human adults on the planet. However, he realizes that he is probably a carrier and could infect the
Enterprise if he were to return. Doctor
Leonard McCoy (
DeForest Kelley) manages to devise a cure, allowing the team to return to the ship. on the
USS Enterprise|upright=1.0|left When Simon van Gelder enters the bridge armed with a
phaser in "
Dagger of the Mind", Spock subdues him with a nerve pinch. He later conducts a
mind meld with van Gelder as part of the investigation into the activities of the nearby colony. After power to the colony is shut down, and a protective force field drops, Spock leads an away team to rescue Kirk. Spock is reunited with Christopher Pike (
Sean Kenney) in "The Menagerie". Pike had been promoted to Fleet Captain but suffered an accident, resulting in severe burns and confining him to a wheelchair and restricting his communication to yes/no answers via a device connected to his
brainwaves. Spock commits
mutiny and directs the ship to travel to Talos IV, a banned planet. He recounts the events of "The Cage" under a tribunal to Kirk, Pike and Commodore Jose I. Mendez (
Malachi Throne). As the
Enterprise arrives at the planet, Mendez is revealed to be a Talosian illusion. At the same time, the real Mendez communicates from Starfleet, giving permission for Pike to be transported to the planet, and all charges against Spock are dropped. In "
The Galileo Seven", Spock leads a landing party on the shuttlecraft
Galileo, which is damaged and pulled off its course before landing on the planet Taurus II. Lieutenant Boma (
Don Marshall) criticizes Spock's fascination with the weaponry of the natives after the death of Lieutenant Latimer (Rees Vaughn) at their hands. After Scotty uses the power packs of the party's phasers to supply enough energy to get the damaged shuttle back into orbit, Spock decides to dump and ignite the remaining fuel to attract the attention of the
Enterprise. The procedure is successful and the crew on the shuttle are rescued. Spock encounters old acquaintance Leila Kalomi (
Jill Ireland) in "
This Side of Paradise" after joining an away team to the planet Omicron Ceti III. After being affected by mind-altering spores, Spock begins acting out of character and with overt emotion, engaging in a romantic liaison with Kalomi, whom Spock had previously rejected when she made advances toward him. The impact of the spores on him is cured after Kirk goads him into anger, and once freed of the effects, Spock is able to initiate a solution which cures the rest of the crew. Spock attempts to mind meld with the non-humanoid Horta in "
The Devil in the Dark". Following the mind meld, Spock relays the history of the Horta and is able to create peace between the aliens and a nearby colony. Both Spock and Kirk undertake
guerrilla warfare against the occupying
Klingon forces on the planet Organia, prior to the establishment of the Organian Peace Treaty in "
Errand of Mercy". To restore the timeline, he travels with Kirk back to 1930's New York City in "
The City on the Edge of Forever". He uses technology of that period to interface with his
tricorder over the course of the weeks they spend in the period before witnessing Edith Keeler's (
Joan Collins) death.
Season two and three During the premiere episode of the second season, "Amok Time", Spock begins to undergo
pon farr, the Vulcan blood fever, and must mate in the next eight days or die. Kirk disobeys Starfleet orders and takes the
Enterprise to the planet Vulcan so that Spock can undergo the mating ritual. When they arrive, he is reunited with T'Pring (
Arlene Martel), his wife, who wishes to instead be with Stonn (
Lawrence Montaigne), a full-blooded Vulcan. She demands the ritual kal-if-fee fight and selects Kirk as her champion. Kirk accepts without knowing this is a fight to the death. McCoy persuades
T'Pau (
Celia Lovsky) to let him hypospray Kirk to alleviate the issues with Vulcan's thinner atmosphere and make the fight fair. Spock seemingly kills Kirk in the fight. McCoy orders Kirk transported to
sickbay, while Spock is told by T'Pring that it was all a game of logic which would let her be with Stonn no matter the outcome. No longer feeling the effects of the pon farr, Spock returns to the
Enterprise where he discovers that McCoy had injected Kirk with a paralyzing agent which merely simulated death and that the Captain was still alive. Following a transporter accident which transports Kirk, McCoy, Uhura and Scotty to a
Mirror Universe and swaps them with their counterparts in the episode "
Mirror, Mirror", they encounter a different version of Spock. Sporting a beard, he grows suspicious of the activities of the suddenly changed personnel and under Starfleet orders, attempts to kill Kirk. Mirror-Spock is knocked unconscious, and is treated by McCoy while the others head to the transporter to attempt to return to their universe. Spock awakes and mind melds with McCoy to discover why Kirk did not have him killed. Discovering what took place, he agrees to help them return and as he mans the transporter controls, Kirk implores him to take control and save not only the ship but his Terran Empire from implosion at the hands of tyrants. The switch is once again successful, and the crew members return to their relevant universes.
The Motion Picture and the film series At the beginning of
Star Trek: The Motion Picture (1979), Spock is no longer serving in Starfleet, having resigned and returned home to pursue the Vulcan discipline of
Kolinahr. Unable to complete the Kolinahr ritual after he senses the coming of
V'ger, he rejoins Starfleet to aid the
Enterprise crew in their mission. During the film's flashback, set 19 years after the events of "
Unification", and as depicted in the comic miniseries
Star Trek: Countdown, Ambassador Spock (Nimoy) promises the Romulans he will use Vulcan technology to save them from a rogue supernova that threatens to destroy their Empire. He pilots an advanced starship equipped with red matter, a powerful substance able to create artificial
black holes. The mission is only partially successful, and in the aftermath, Spock is pursued into the
past by Nero (
Eric Bana), a Romulan driven mad by the loss of his homeworld and family, setting into motion the events of the film. In the film's opening act, Nero's ship emerges in the year 2233, and through its interaction with the inhabitants, inadvertently creates an "alternate, parallel 'Star Trek' universe". Twenty-five years later, in the new reality, Spock's ship emerges and Nero captures him and the red matter. Stranded in the alternate past, the
prime version of Spock helps the
alternate, younger version of himself and Kirk (
Zachary Quinto and
Chris Pine, respectively) thwart Nero's attempt to destroy the Federation. The film also features
Jacob Kogan in several scenes depicting Spock's childhood, including his abuse at the hands of other Vulcan children due to his half-Human heritage, and his relationship with his parents (
Ben Cross and
Winona Ryder). The film also depicts Kirk and Spock's initial clashes at Starfleet Academy, and the gradual development of their friendship based on shared mutual respect, A major change in characterization from the primary timeline is alternate Spock's involvement with alternate
Uhura (
Zoe Saldaña), his former student. At the end of the film, the young Spock opts to remain in Starfleet while his older self stays in the altered universe to aid the few surviving Vulcan refugees, as Nero had destroyed Vulcan, Spock's home planet.
Star Trek Into Darkness (2013) In
Star Trek Into Darkness, Spock Prime is described as living on 'New Vulcan' while the younger Spock remains aboard the
Enterprise, struggling with the loss of his home world, as well as his relationships with
Uhura and
James T. Kirk. Spock nearly dies protecting a planet from an active volcano, but Kirk breaks the Prime Directive and saves him. Spock Prime is contacted by Spock on the
Enterprise, to find out details on Khan. Spock Prime initially reminds his alternate self that he will not interfere with the events in the alternate timeline. That being said, he then informs Spock that Khan was a dangerous man, and the greatest threat that the
Enterprise ever faced in his own timeline, and warns that he is likely as dangerous in Spock's alternate timeline as well. When asked whether Khan was defeated, Spock Prime answers that he eventually was defeated, but at great cost (referring to the events of
Star Trek II: The Wrath of Khan). When Kirk contracts radiation poisoning and dies in front of Spock (a transposed parallel of events in the prime timeline where Spock dies in front of Kirk), an enraged and vengeful Spock attempts to kill Khan to avenge Kirk before Uhura informs him that Khan's regenerative blood can revive Kirk. Nearly a year later, Spock remains as Kirk's chief science officer and executive officer as the
Enterprise departs on its first five-year mission of deep-space exploration.
Into Darkness would be Nimoy's final appearance as Spock Prime, as well as the last role of his career. He died in 2015, shortly before production began on
Star Trek Beyond.
Star Trek Beyond (2016) In
Star Trek Beyond, Spock receives word that Ambassador Spock (Spock Prime) has died. Impacted by this, Spock later tells McCoy that he intends to leave Starfleet to continue the ambassador's work on New Vulcan. At the end of the film, Spock receives a box containing some of Ambassador Spock's personal effects, and reflecting on a photograph of the older crew of the
Enterprise from the series' original timeline, he chooses to remain in Starfleet.
Star Trek: Discovery portrays Spock in
Star Trek: Discovery and
Star Trek: Strange New Worlds. In August 2018, it was announced that
