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.

His mother served as regent until the boy came of age to rule.

Later, in the Star Trek: Deep Space Nine relaunch novels, Akaar is a veteran admiral in the fleet.

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.

Arex Voice: James Doohan 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. 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. 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 (given as "Edoans" in Alan Dean Foster's novelizations of the animated episodes, but as "Triexians" in Peter David's New Frontier series) and had three arms and legs.

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.
