In 2155, he was serving in the operations divison of the ISS Enterprise. That year, he was the test subject for a demonstration of the new agony booth designed by Major Malcolm Reed and Doctor Phlox. Reed was uncertain of the nature of Terev's transgression, believing that he was late for a duty shift, but noted that "all Tellarites are guilty of something." (ENT episode: "In a Mirror, Darkly")
- It is unknown if Terev has a counterpart in the primary universe, though the performer who played him also played a number of Tellarites in other episodes.
- Terev either died in the destruction of Enterprise or the later destruction of the ISS Avenger
