Spock

Spock is a fictional character in the Star Trek media franchise. A half-Vulcan, half-human science officer and first officer of the starship USS Enterprise in the original series, he later appears as a senior Starfleet officer in films and other media. Spock was born in 2230 to Vulcan ambassador Sarek and human mother Amanda Grayson.

Created by Gene Roddenberry, Spock was portrayed by Leonard Nimoy in The Original Series (1966–1969) and in the subsequent Star Trek films; in the film reboot series beginning with 2009, he is played by Zachary Quinto. Nimoy and Quinto helped define the character’s portrayal, including the Vulcan salute and the phrase Live long and prosper.

Characterized by logic and emotional restraint, Spock often negotiates between Vulcan reason and human emotion. He is known for the Vulcan nerve pinch and for roles in storylines such as the Pon farr mating ritual in Amok Time; his bond with Kirk and his dual heritage are recurring themes across the series and films.

Spock is one of science fiction’s most enduring figures, shaping depictions of science, diplomacy, and cross-cultural friendship in Star Trek. He remains a central reference in popular culture, appearing in books, comics, games, and fan works.
