Captain James Tiberius Kirk - Star Trek - The Original Series

James Kirk from Star Trek - The Original Series played by William Shatner

James Kirk is a fictional male Human captain in the Star Trek - The Original Series television series who was played on screen by William Shatner, Christopher Pine. James Kirk holds the rank of Captain within the USS Enterprise NCC-1701A.

Captain Kirk is synonymous with USS Enterprise NCC-1701A although he was not the first captain of the ship. The first captain was Christopher Pike but he didn't last long because the broadcasters and producers didn't like him. Christopher Pike had a more prominent role in the rebooted film series as he was the one who got Kirk to enrole at Space Academy and appeared in the first two films before being killed.

Captain Kirk's Main Enemies

During his tenure as Captain, he has had many encounters with Romulans and Klingons.

During his years, he had to visit planets which modelled on old periods of time. He has encounter Romans, World War II and a planet modelled on the 1920's Prohibition period. When reminded of the Prime Directive in the period of old, he counters by saying that the planets already been corrupted, he's just trying to sort things out.

Khan Noonien Singh

His most memorable solo enemy is Khan Noonien Singh who he defeated in Space Seed but then who came back for revenge in Star Trek II, the Wrath of Khan. In the re-imagined storyline, Kirk and Spock face John Harrison whose real name is Khan.

Khan is a genetically engineered human who was found in stasis. When Khan and his people start causing trouble onboard the Enterprise, Kirk has no option but to set them down on a planet. Years later, Pavel Chekov encounters Khan on a desert planet. Khan wants access to the Genesis machine.


The Klingons are the most memorable alien race enemies of Captain Kirk. Romulans are also notable but not as memorable. Everyone remembers the Klingons.

The first time Kirk encounters the Klingons is in Errand of Mercy. The Klingons under the leadership of Kor takes control of the planet Organia after Kirk and Spock have beemed down to the planet. The planet resembles a medievel environment and the inhabitents are relunctant to overthrow the Klingons. Kirk and Spock must somehow force the Klingons to leave.

The prime directive of the United Space Federation is not pass on technology to civilisation that are not technically advanced enough to have come up with the technology themselves. Kirk blatantly breaks this after he becomes aware that Klingons are arming and teaching one faction on a planet to kill the other. This is documented in A Private Little War.

Kirks death is at the hands of Doctor Tolian Soran in the film Star Trek VII, Generations after being pushed off a cliff.

Captain Kirk's Early Years

Captain James Tiberius Kirk played by Chris Pine

In the original timeline, Kirk was born in Riverside, Iowa but in the Rebooted version, he was born out in space during an Romulan attack on the ship his father was captain of.

Much of his teenage years and his entry into Space Academy comes from the beginning of Star Trek XI where he was a deliquent and a tear away before being given another chance by Christopher Pike. He takes up the offer and graduated in a speedy time but he is not yet Captain of the Enterprise. The first Captain is Spock in the film before Spock is forced to stand down.

Despite his initial disagreement with Spock, they become life long friends. Kirk also counts Doctor Leonard Bones McCoy as a close friend who as we see helps Kirk get through the Space Academy.

Captain Kirk's Relationship with Women

Kirk comes across as a womaniser trying his luck with an Orion female and then with Lieutenant Uhura, both conquests fail. In the episode Plato's Stepchildren, Kirk kisses Uhura which is the first inter-racial kiss ever seen on television.

In Star Trek II, the Wrath of Khan, we learn he had a tryst with Doctor Carol Marcus had that produced a son Jason who is killed by a Klingon in Star Trek III, the Search for Spock. In the updated version of the storyline, Kirk comes across Eve Marcus when he's having to deal with a threat from John Harrison, an Federation agent turned terrorist.
