aid of a fleet of Phylosian ships and a giant clone of Spock that he's created by transferring Spock's consciousness into it, leaving Spock's original body a mindless shell. The newly awakened Spock Two uses his Vulcan telepathic abilities to mind meld with his original self and save his life. The two Spocks, in concert with Captain James T. Kirk, convince Keniclius that the need for his plan no longer exists. Spock Two and Keniclius Five devote themselves to restoring the Phylosian civilization as Spock One departs with his shipmates. Production Walter Koenig joined the main cast of Star Trek: The Original Series during the second season as Pavel Chekov and continued to appear in the series until it was cancelled at the end of season three. Although the remaining main cast of the series were hired as voice actors for Star Trek: The Animated Series, Koenig was not brought in due to financial constraints. He only found out about his omission from the show when Sackett announced it on stage at a Star Trek convention he was attending. His character was replaced by a new animated character voiced by James Doohan. Koenig first became involved with writing a script for The Animated Series after he asked Susan Sackett, Star Trek creator Gene Roddenberry's assistant, to type up some writing he was working on. After reading it through, she thought it was good and passed it to Roddenberry, who agreed and asked Koenig if he was interested in writing for the animated show. He accepted the offer, and started working on a plot involving cloning which was inspired by newspaper articles about the subject, becoming the first actor from Star Trek to write for the franchise. He found the writing process for "The Infinite Vulcan" "unbearable". This was due to interference from Roddenberry, resulting in Koenig producing ten drafts of the screenplay, and because of Koenig's frustration in not otherwise being involved in the series. He could not understand why so many redrafts were required, a view shared by story editor/associate producer D.C. Fontana. Roddenberry was keen in particular to make use of the benefits of an animated medium, by including things which could not have been shown on a live-action series. These included "talking vegetables" as characters, which Koenig said were not his idea but were so silly as to not be worthy of a fight. David Alexander, in
