Spock – full name generally considered unpronounceable to Humans – was a male Human/Vulcan hybrid who became one of the most distinguished and respected figures in the United Federation of Planets.

As a Starfleet officer in the 23rd century, he 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 vessel. 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 died on New Vulcan in 2263 of the alternate reality.
