This article is about the 23rd century officer. You may be looking for the commanding officer of the USS Kirk in the 25th century, Thelin (captain).

Thelin th'Valrass was a half-Andorian/half-Aenar thaan who served in Starfleet in the 23rd century. (TAS episode: "Yesteryear"; TOS novels: The Fire and the Rose, The Chimes at Midnight, The Tears of Eridanus)

Biography[edit | edit source]

Commander Thelin served as second-in-command of the USS Ticonderoga. One year after his posting, he was killed in an avalanche during a survey of an unexplored planet. (TOS novel: The Fire and the Rose)

Alternate timelines[edit | edit source]

In an alternate timeline created by the death of Spock in 2237, Thelin became first officer aboard the USS Enterprise in 2264, and continued to serve in that capacity until 2269, when he resigned from Starfleet and joined the Andorian Science Institute. (TAS episode: "Yesteryear"; TOS - Myriad Universes novel: The Chimes at Midnight)

In 2274, Thelin was engaged to Thali sh'Dani but the Eveste Elders would not allow them to mate so they broke up. Due to the trauma of this event, Thelin decided to rejoin Starfleet. He was subsequently promoted to captain and given command of the Enterprise at some point before engaging Khan Noonien Singh.

Thelin was present at the destruction of the Enterprise by Commander Kruge in 2285 and the ravaging of Earth by the Cetacean Probe in 2286. He also led the attempt to reclaim Earth's atmosphere aboard the USS Copernicus, but was stopped when the Klingons invaded Earth.

In the ensuing war, Thelin was promoted to admiral and led forces in combat, including a successful campaign in the Archanis sector. He was then chosen to take the IKS Katai, a Klingon bird-of-prey which Thelin had captured, and deploy the Genesis Device on Praxis, ending the war. After this action, Thelin was considered a war criminal by the Klingons and was voluntarily extradited to the Klingon Empire for trial to maintain the new, fragile peace. (TOS - Myriad Universes novel: The Chimes at Midnight)

In a reality where Vulcans remained a violent and emotional species, Thelin Th'Valrass served in the Interstellar Guard as commanding officer of the IUES Kumari II. Commander Thelin and his first officer, Hikaru Sulu, had a rather antagonistic relationship, until Thelin was killed when a Klingon terrorist detonated a bomb on Thelin's ship and Sulu became commander of the Kumari. It was also mentioned that Thelin served as the Kumari's first executive officer under Commander Lamia until her promotion to general officer rank. (ST - Myriad Universes novel: The Tears of Eridanus)
