Species : Humans
A longtime friend of Captain Kirk, Gary Mitchell was the helm officer of the USS Enterprise in 2265 when the ship attempted to explore beyond the edge of the galaxy. He was born and raised in Eldman city and was 23 at the time of the mission. Mitchell was 5 feet 9 inches tall and weighed between 160 and 169 pounds. He had a very high ESP rating for a Human being - his esper rating was 091, his aperception quotient was 20/104, and his Duke-Heidelburg Quotient was 261. On Deneb IV Mitchell showed a marked ability in sensing the telepathic communication used by the natives, allowing him to carry on long telepathic communication with them on three occasions. As a child he displayed a better than average ability in guessing games and showed some and ability in elementary magician's tricks. There was a strong tendency towards esper orientation in his maternal bloodline, dating back through at least six generations. One of his female ancestors was known to be interested in spiritual readings.
At the academy Mitchell studied under Lieutenant Kirk, and devised a plan to lessen the demands of the class by aiming a 'little blonde lab technician' at Kirk. Mitchell claimed to have outlined her whole campaign for her, apparently with great success as Kirk recalled that he had nearly married the girl.2 The two would go on to serve together after the academy; on a mission to Dimorus Mitchell stepped in the way of a poison dart thrown at Kirk by the rodent-like beings which inhabited the planet. He almost died as a result.
His ESP abilities were boosted to god-like levels by the USS Enterprise's encounter with the energy barrier at the edge of the galaxy. Mitchell subsequently became more and more arrogant about his powers, considering Humans as lowly beings worthy of contempt. He was killed by Kirk with the assistance of Elizabeth Dehner, who had developed powers close to Mitchell's during the same incident.3
