"I carry my sword in my hand. You carry yours in your heart, and your mind. The way I see it, that gives you a two-to-one advantage in arms. Be fair, Citizen G'Kar."
- – Ta'Lon, to G'Kar
Ta'Lon was a Narn warrior and later an ambassador. He was rarely without his K'tok.
In 2259, just before the Narn-Centauri War, Ta'Lon was captured by a Streib ship while on patrol. After being tortured and experimented upon, he was forced to battle other prisoners via a mind control device. The last gladiator he faced was Captain John Sheridan, who managed to knock him out and disable the control device. Working together, they were able to escape the Streib vessel in a life pod when the EAS Agamemnon tracked down and engaged the ship. Ta'Lon was taken back to Babylon 5 to be treated for his injuries. He was then sent back to Narn and got caught up in the War.
Ta'Lon survived the war, including the Centauri bombardment of Narn itself. Afterwards, he became a bodyguard for Na'Far, a Narn working for the Centauri provisional government. Na'Far was sent to Babylon 5 to try to convince G'Kar to surrender himself. Before Na'Far speaks with G'Kar, Ta'Lon meets with Captain Sheridan for a drink, vowing to repay Sheridan for saving his life. Indeed, Captain Sheridan was glad to see Ta'Lon again and as the two talked, Sheridan wondered with a bit of humor what people would think if he started walking around with Ta'Lon as his bodyguard; to which Ta'Lon answered in an amused voice that people would say what a lucky man Sheridan was because he would live to be 150. The following day, Na'Far nearly succeeded when G'Kar saw how his place may be causing division in the Narn Resistance. However, after the Narn community begged G'Kar to stay, he reconsidered. Ta'Lon, inspired by G'Kar and disgusted with Na'Far, he decided to join the community (and indeed had been one of the instrumental voices in convincing G'Kar to stay).
A few weeks later, G'Kar was arrested for assaulting Ambassador Londo Mollari while under the influence of Dust and placed in station lockup. Ta'Lon kept a vigil outside his quarters for over a month, fasting and remaining awake for days at a time. When G'Kar was released, Ta'Lon became his closest confidante. He explained the revelation he had had, and how the Narn would have to fight to protect Babylon 5 in order for everyone to survive the oncoming Shadow War. Ta'Lon joined the station's new security team along with most of the other Narns on station.
- Ta'Lon first appeared in "All Alone in the Night", but was not named in the episode, listed in the credits simply as "Narn". He would not get a name until his appearance in "A Day in the Strife".
