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.[3] 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.[4] 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[5] (given as "Edosians" 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.

  17. ^ 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 Admiral "Fitzgerald" was never named in dialogue, it can be disregarded and "Barstow" retconned in its place. However, Derr is identified as "Fitzgerald" in the ending credits (and the script), so canon demands that "Fitzgerald" stand as a different role for the same actor, as with other actors in the Trek universe.
