Ukrainian in descent, Yar was born on a failed Federation colony on planet Turkana IV. Her parents were killed when she was only five, and she spent much of her childhood in a bitter struggle for survival, evading rape gangs and caring for her younger sister Ishara. TNG Legacy. One of the few "normal" aspects of her childhood was her ownership of a pet cat that she protected. Tasha escaped from Turkana IV at the age of 15, choosing to join Starfleet. As a Starfleet officer she impressed Captain Jean-Luc Picard with her courage in rescuing a wounded colonist, making her way through a Carnellian mine field. Thus Picard requested that she be transferred to the Enterprise-D in early 2364. In 2364, Yar transported Captain Picard to the Enterprise-D when he took command of the ship. TNG All Good Things.... While under the influence of the Psi 2000 virus in early 2364, Tasha became intimate with Data. Yar was killed in late 2364 while participating in a rescue mission on planet Vagra II. Tasha, knowing her line of work entailed considerable risk, left a holographic farewell to her comrades in which she thanked her shipmates for being part of her life. TNG (Season 1). Data kept a small holographic portrait of Tasha, and he considered it one of his most precious personal possessions. TNG The Measure of a Man. In the alternative timeline created when the Enterprise-C vanished from its proper place in 2344 into a temporal rift, Enterprise-D Security Chief Tasha Yar did not die at planet Vagra II in 2364. Instead, she remained as security officer aboard the Enterprise-D during a war between the Federation and the Klingons. The alternate Yar was on duty when the Enterprise-C emerged from a temporal rift, and she served as liaison between the two ships, working closely with Lt. JG Richard Castillo, with whom she became romantically involved. When it was learned that the Enterprise-C had to return to the past, the alternate Yar volunteered to return with that ship, despite the knowledge that the mission meant virtually certain death. TNG Yesterday's Enterprise. No direct evidence survived of the existence of the alternate Yar after the return of the Enterprise-C to the past. However, in 2367, a Romulan operative named Sela began a series of covert operations against the Klingon government. Sela was apparently the child of Yar and a Romulan general who had captured the Enterprise-C bridge crew at Narendra III. The Romulan general agreed to spare the bridge crew if Yar agreed to become his consort. Sela was born a year later, in 2345. Sela claimed that the alternate Yar was killed trying to escape when Sela was four. TNG Redemption, Part 1 & 2. In 2368, Cmdr. Riker mentioned Tasha Yar when Worf wanted to commit suicide after he was paralyzed in accident. TNG Ethics.
