James T. Kirk (android)

The Kirk android on Exo-III, demonstrating its knowledge of Kirk's brother

In 2266, Roger Korby used the android duplicator to make a very close copy of Captain Kirk, the Kirk android. Although initially intended only to impress Kirk and gain his cooperation in exploiting a new planet, the duplicate served to impersonate him once Korby realized his cooperation was not forthcoming.

During the copying of his memories into the android, Kirk had held a marked antagonism towards his first officer in the forefront of his consciousness, repeating the phrase "Mind your own business Mr. Spock! I'm sick of your half-breed interference, do you hear?" Aboard the USS Enterprise on a mission for Korby, the duplicate used Kirk's phrase in order to avoid Spock's observation. As it was, however, completely out of character, the phrase alerted Spock to the fact that his captain was in trouble.

Back under the surface of Exo III, the android duplicate was destroyed by Andrea when it rebuffed her sexual advance, terming her wish to kiss "illogical". She was armed with a laser pistol, since Korby had just ordered her to protect the cavern base from Spock's landing party. (TOS: "What Are Little Girls Made Of?")

Andrea's dreadful reaction followed from the logical and emotional confusion Kirk had stirred by desiring her – or seeming to do so – even after she explained to him "I am not programmed for you". The Kirk android, whose duplication was finished before this romantic scene, remained ignorant of their history.

The Kirk android was played by William Shatner for frontal shots, and by Eddie Paskey from the back when appearing at the same time as the real Kirk.
