Spock – full name generally considered unpronounceable by Humans – was a male Human/Vulcan hybrid who lived during the 23rd and 24th century. He became one of the most distinguished and respected figures in the United Federation of Planets.
As a Starfleet officer in the 23rd century, Spock served aboard the starship USS Enterprise as science officer under Captain Christopher Pike, as first officer and science officer under Captain James T. Kirk, and as the commanding officer of the Enterprise during its tenure as a training ship.
In the 24th century, Spock became an adviser to the leadership of the Federation and a celebrated ambassador on their behalf. He disappeared in 2387 after saving the Federation from a supernova that destroyed Romulus and caused the creation of the alternate reality. Spock spent the remainder of his life in the alternate timeline.
