Spock

Spock is a fictional character in the Star Trek media franchise. Portrayed by Leonard Nimoy, he is one of the three central characters in the original Star Trek series (1966–69), alongside Captain James T. Kirk (William Shatner) and Dr. Leonard "Bones" McCoy (DeForest Kelley). On that series, Spock served as first officer and science officer of the starship Enterprise. Spock's mixed human–Vulcan heritage serves as an important plot element in many of the character's appearances. As one of the most popular Star Trek characters, Spock has made return appearances in many later installments of the franchise.

Spock was played by Nimoy in the original Star Trek series, Star Trek: The Animated Series, eight of the Star Trek feature films, and a two-part episode of Star Trek: The Next Generation. Multiple actors have played the character since Nimoy; the most recent portrayal is Ethan Peck, who since 2019 has portrayed Spock at an earlier period of his career than the original series, appearing in the second season of Star Trek: Discovery, in Star Trek: Short Treks, and as a main character in Star Trek: Strange New Worlds. Additionally, Zachary Quinto played an alternate-reality version of Spock in the feature films Star Trek (2009), Star Trek Into Darkness (2013), and Star Trek Beyond (2016). Although the three films are set in the aforementioned alternate reality, Nimoy appears in the first two as the original timeline's Spock.
