Star Trek Expanded Universe
For the Avalon Universe counterpart, see Kelvar Garth (Avalon Universe).

Garth (known as Garth of Izar) was a Starfleet line officer on active duty during the 23rd century. (TOS: "Whom Gods Destroy")

The episode gave Garth no other name. Fan fiction has sometimes assumed that this is his surname. FASA materials refer to him as "Kelvar Leonard Garth" (FASA RPG: The Four Years War).

Garth was renowned for his victory at Axanar, which was studied thereafter at Starfleet Academy. James T. Kirk, as a midshipman, regarded Garth as one of his heroes.

After a transporter accident at Antos IV, the indigenes of that world taught Garth to heal through cellular metamorphosis. This apparently drove him mad and Garth attempted to destroy the Antosians but was prevented from doing so. However, Garth killed both his executive officer and second officer. (TOS novel: Garth of Izar)

Garth was court-martialled and charged with murder. He was then sentenced to rehabilitation at the Federation penal colony on Elba II.

In 2268, when USS Enterprise was delivering a new therapy to the colony, Garth masqueraded as Governor Donald Cory and kidnapped both Kirk and Spock. After their release, the therapy was administered to Garth.

Towards the end of Kirk's first five-year mission, Garth was considered fit for duty. He was present at a memorial service for Enterprise officers at Starbase 4. (Star Trek: Phase II: "Going Boldly")


By the 24th century, the Garth Tactical College existed at Starfleet Academy. One of its instructors was Admiral Matthias Jeffries. (The Romulan War: "The Romulan War (Part 1)")
