| Description | ||
| Leonard James Akaar (Memory Alpha article) | Friday's Child (TOS) | |
| Son of the late Teer Akaar and his widow Eleen on the planet Capella IV. Born 2267 shortly after his father was killed in a Klingon-induced power struggle, he was named after James T. Kirk and Leonard McCoy, who helped to resolve the local conflict. Leonard James Akaar inherited the title of "teer," or chief, of the Ten Tribes of Capella IV. His mother served as regent until the boy came of age to rule. In the novels, Akaar grows up and joins Starfleet; we first see him serving as chief of security on the USS Excelsior under Captain Hikaru Sulu. Later, in the Star Trek: Deep Space Nine relaunch novels, Akaar is a veteran admiral in the fleet. | ||
| Akorem Laan (Memory Alpha article) | Richard Libertini (Memory Alpha article) | Accession (DS9) |
| Bajoran poet best known for The Call of the Prophets. Traveling in a Bajoran lightship, Akorem was the first to find the Celestial Temple (the wormhole to the Gamma Quadrant); when he emerged about 200 years later, Benjamin Sisko gave up his title of Emissary so that Akorem could take it, a decision Sisko regretted when Akorem advocated a return to the D'Jarras (the Bajoran caste system). Sisko and Akorem went to the wormhole together, and the Prophets decided to send Akorem back to his time and reinstate Sisko as their Emissary. | ||
| Alixus (Memory Alpha article) | Gail Strickland (Memory Alpha article) | Paradise (DS9) |
| Leader of a colony that settled on planet Orellius in 2360, responsible for several deaths because she rejected any form of technologically-based medicine. | ||

However, Almak's fleet opens fire on the Prometheus when he learns that Rekar is no longer in control of it. (Discrepancy Note: The voice-over actor clearly identifies the character as "Almak," but the closed-captioning reads "Almar" and The Star Trek Encyclopedia lists him as "Almar." There must have been a last-minute change that differs from the shooting script.) | ||
| Altovar (Memory Alpha article) | Victor Rivers (Memory Alpha article) | Distant Voices (DS9) |
| Lethean criminal who was caught stealing bio-mimetic gel from Deep Space Nine in 2371. | ||

| Ardra (Memory Alpha article) | Marta DuBois (Memory Alpha article) | Devil's Due (TNG) |
| According to the theology of Ventax II, Ardra was a mythic being from the distant past who promised the population a thousand years of prosperity, followed by enslavement upon her return at the end of that epoch. In 2367, a female con artist was unmasked by Enterprise-D personnel after deceiving the Ventaxians into believing she was the deity by using technology to mimic various phenomena believed to herald Ardra's return. | ||
| Arex (Memory Alpha article) | Voice: James Doohan (Memory Alpha article) | Beyond the Farthest Star (TAS) recurring thereafter |
| Lieutenant Arex, voiced by James Doohan, was a recurring character on Star Trek: The Animated Series which ran on NBC from 1973 to 1974.[1] The series' writers and artists were able to create his unique alien look because the series was animated; creating such a character with a live-action actor in make-up would not have been feasible.[2] The character was later used in Star Trek novels and comics.
Arex was a Starfleet officer assigned to the USS Enterprise as navigator. Arex was a member of a tripedal species (the Edosians) and had three arms and legs.[3] Arex also sometimes took the conn, but he rarely left the ship on landing party missions. |

| Although he may appear to be nervous and lacking in confidence, Reginald "Reg" Barclay is a highly talented Starfleet systems diagnostic engineer. Stationed aboard the Enterprise-D from 2366, Barclay had a tendency to spend more time inside the holodeck than in real social situations. He also suffered from severe transporter phobia in 2369, although he seems to have overcome this psychological barrier. He also spent time at Jupiter Station as Dr. Lewis Zimmerman's assistant on his EMH project.
While stationed aboard the USS Enterprise-E in 2373, and through a strange turn of events involving the Borg, Barclay was able to meet one of his idols, Zefram Cochrane.

Future's End (VOY) Relativity (VOY) |
| A native of the 29th century, he is the pilot of the Federation timeship Aeon in one timeline, and captain of the Federation timeship USS Relativity in another.
Braxton traveled to the year 2373 to destroy the USS Voyager to stop it obliterating Earth's Solar System in the 29th century with a temporal explosion. In confronting Voyager, Braxton's ship was thrown back in time, where it crash-landed on Earth in 1967. Braxton survived the crash, but became separated from his ship which was salvaged by entrepreneur Henry Starling, leaving Braxton homeless and destitute. Captain Janeway and her crew tracked down the Aeon, destroying it and preventing the destruction of Earth in the 29th century. A new timeline was created and allowed Braxton to instead escort Voyager back to the 24th century. In a later episode, Braxton commanded the Relativity in an effort to prevent a saboteur from destroying Voyager with a weapon designed to fracture spacetime. Recruiting Seven of Nine to help, the crew of the timeship discovered an older version of Braxton who suffered temporal psychosis and blamed Voyager for his circumstances; this Braxton was forced to retire after the stress of cleaning up after Voyager. He was apprehended and the younger Braxton on the Relativity arrested. The different versions of Braxton were re-integrated to stand trial, but he was guaranteed leniency in exchange for revealing the precise moment he boarded Voyager to plant the weapon. |

| A proud young Romulan officer who served aboard the Praetor's flagship Bird-of-Prey in 2266. He dispatched a coded message to the Praetor while the ship was under cloak, thereby breaking the "rule of silence." For this infraction, he was reduced two steps in rank. Later, he was ordered to place a nuclear warhead with a proximity fuse among the debris that was to be jettisoned from the ship. This maneuver succeeded in severely damaging the Enterprise. Decius was viewed by the ship's elder Centurion as having powerful friends who may not appreciate his being demoted, and which could mean danger for the ship's Commander. | ||
| Willard Decker (Memory Alpha article) | Stephen Collins (Memory Alpha article) | TMP |
| Captain of the USS Enterprise before joining with V'ger, son of Commodore Matt Decker[5].

In "The Squire of Gothos," DeSalle is part of the landing party that encounters Trelane. In "This Side of Paradise," DeSalle discovers that the colonists on Omicron Ceti III are the only life forms to survive exposure to the planet's Berthold rays. He also performs a quantitative analysis of the crops being grown by the colonists. In "Catspaw," DeSalle commands the Enterprise while Captain Kirk, Commander Spock and Lieutenant Commander Scott are being held prisoner on the surface of Pyris VII. He directs the crew's effort to pierce an alien force field to rescue the landing party. (Conjecture: The Star Trek Concordance, by Bjo Trimble, lists his first name as "Vincent.") | ||

| Donatra (Memory Alpha article) | Dina Meyer (Memory Alpha article) | NEM |
| Romulan commander of the IRW Valdore. She attempts to ingratiate herself to Praetor Shinzon by flirting with him, but he prefers that she demonstrate her allegiance by watching Commander Suran, whose impatience and lack of respect have given Shinzon pause. Donatra fears that a war with the Federation will mark Romulan children for generations to come. She eventually rejects Shinzon and fights with the Enterprise-E against the Reman Warbird Scimitar. Although the Valdore is severely damaged in battle, Donatra is able to offer aid to the ram-damaged Enterprise after the Scimitar is destroyed. | ||

Later, when Elaan sheds tears (which act as a "super love potion") because she feels that nobody likes her, Kirk wipes them away and immediately becomes biochemically attracted to her.

Fitzgerald has no choice because Spock cannot prove that Kirk's life is in danger. (Casting Note: Richard Derr also played Commodore Barstow in "The Alternative Factor." In the interest of continuity, some Star Trek fans have suggested that, since "Fitzgerald" was never named in dialogue, it can be disregarded and "Barstow" retconned in its place. However, "Fitzgerald" is identified in the script and in the ending credits, so, regardless of the oversight regarding the actor's two roles, canon demands that "Fitzgerald" should stand.) | ||
