James T. Kirk (alternates)

Throughout the history of the universe, there have been multiple timelines, alternate realities and parallel universes that have all contained versions of James T. Kirk, as well as various clones and replicants.

Coalition timeline
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 destroyed a transport carrying his wife and son. By then, he was serving as first officer aboard UESS 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.

Klingon James T. Kirk
In the quantum rift, a reality in which James T. Kirk was a Klingon briefly intersected with the reality of the Enterprise. 

Duplicates
A copy of Kirk was made when the android duplicate of Roger Korby made one of him when Kirk refused to do what he asked. 

Another Kirk was created from transporter malfunction. This Kirk was seen as an evil and alter ego of Kirk.
