The historical Tombstone outlaws of 1881 whose identities the Melkotians imposed on Kirk, Spock, McCoy, Scott and Chekov, condemning them to face the Earps at the O.K. Corral.
The Clanton gang was a group of cowboys and rustlers in Arizona Territory who lost the gunfight at the O.K. Corral on 26 October 1881. The Melkotians draw the scene from Kirk's memory as a means of execution after the Enterprise ignores a warning buoy.
In Spectre of the Gun, the landing party find themselves in a half-built Tombstone where everyone takes them for the gang. Kirk is Ike Clanton, Spock and McCoy are Frank and Tom McLaury, Scott is Billy Claiborne and Chekov is Billy Clanton. Wyatt, Virgil and Morgan Earp and Doc Holliday mean to kill them at five o'clock.
Chekov is shot by Morgan Earp over a woman. Spock deduces that nothing there is real unless they believe it, and a mind meld leaves the others certain the bullets cannot harm them. Kirk beats Wyatt Earp but will not kill him.
