The Melkotians, also called Melkots, are a telepathic alien race with whom first
contact was made in 2268. The Melkotians spurned, by the use of an orbiting warning buoy, the Enterprise's initial contact overtures. When Enterprise captain Kirk ignored the Melkotian warning, the aliens subjected Kirk and company to an elaborate charade in which images from Kirk's memory where intended to be the device of their deaths. The Melkotians' drama took the form of the famous gunfight at the OK Corral at Tombstone, Arizona, on Octobber 26, 1881, between the Earps and Clantons, a fight that the Clantons lost. Kirk and members of his Enterprise crew were to fill their shoes, but managed to avoid death in the legendary gun battle. Kirk was later successful in opening diplomatic relations with the reclusive Melkotians.
