James T. KirksEdit
Other versions of James T. KirkEdit
In an alternate timeline in which John Frederick Paxton destroyed Starfleet Command and ended the talks for the Coalition of Planets in 2155, James T. Kirk became resentful of aliens in general and Vulcans in particular when the Interstellar Coalition starship ICV Vanik destroyed a transport carrying his wife and son. By then, he was serving as first officer aboard UESS Enterprise under Captain Christopher Pike. Six months later, in 2264, had to face his prejudices when the Enterprise carried Lady T'Pol to Babel to negotiate United Earth's admission to the Interstellar Coalition.

In another alternate timeline in which the Vulcans had remained a violent and emotional species, James T. Kirk commanded the IUES Enterprise I, a Charter-class starship of the Interstellar Guard in service in the 2260s. Many of his crewmates went on to have successful careers in the Guard, including his first officer, Gav, who became a Brigadier General in the Security Bureau, tactical officer Lamia, who became a Major General on Field Marshal Thelianaresth th'Vorothishria's staff, and astrophysicist Hikaru Sulu, who served as Captain of the IUES Kumari II, the flagship of the IG Fleet.
