Kirk as Ike Clanton at Tombstone
Ike Clanton was a 19th century Human gunman who was involved in the shootout at the OK Corral on October 26, 1881. Ike was one of two survivors on the losing side of the duel.
In 2268, James T. Kirk was identified as Ike Clanton in a bizarre recreation of the duel created by the Melkot. (TOS: "Spectre of the Gun")
