The youngest cast member of Star Trek: The Original Series, Pavel Chekov (Walter Koenig) began his Star Trek career as an ensign aboard the USS Enterprise of Captain James T. Kirk (William Shatner). Chekov joined TOS at the beginning of the show’s second season and most often served as the ship’s navigator. Chekov was exceptionally proud of his Russian heritage and took every opportunity to highlight the supposed history of his homeland, although most of his “facts” were incorrect. Throughout TOS and its subsequent films, Chekov proved to be a loyal and competent Starfleet officer.
