The seventh episode of the animated Star Trek series premieres on NBC, written by original series cast member Walter “Chekov” Koenig, who is not reprising his role for the animated series. 
Stardate 5554.4: A visit to a previously uncharted planet reveals an advanced laboratory, and a race of mobile plant life, the Phylosians. These beings prove to be friendly enough when they cure Sulu of the effects of a local poison. But when an a flock of airborne creatures aid in the abduction of Spock, a seemingly giant human being appears, claiming to be the long-lost Dr. Keniclius – a geneticist who was banished for his attempts to create a master race during the disastrous Eugenics Wars. Keniclius claims that he needs Spock to create a clone-army of beings to “enforce” peace upon the entire galaxy – but after seeing that the Phylosians have a hangar full of spacecraft, Kirk is suspicious of Keniclius’ goals.
