Alternate timelines and realities[]
Yesterday's Enterprise timelines[]
In an alternate timeline created when the USS Enterprise-C was accidentally sent through a temporal rift from 2344 to 2366, the Federation had been at war with the Klingon Empire for almost 20 years as the Enterprise-C's disappearance resulted in the destruction of the Klingon colony Narendra III. In this timeline, Tasha Yar never encountered Armus and, consequently, did not die in 2364. By 2366, she was an officer in a far more militarized Starfleet than that of the proper timeline.
This Tasha Yar traveled back in time aboard the Enterprise-C and ended up in 2409 after the temporal rift was destabilized. After returning to 2344, Tasha was captured shortly before the ship's destruction. She agreed to become the consort of General Volskiar in order to save the lives of the ship's surviving crewmembers. She gave birth to a half-Romulan daughter, Sela, and died in 2349 while trying to escape back to Federation space. (TNG episode: "Yesterday's Enterprise"; TNG novel: Death in Winter; TOS novel: Vulcan's Heart; STO mission: "Temporal Ambassador")
Following the attempted escape, Sela believed her mother to have been executed. Yar and the Enterprise-C survivors from 2344 and 2409 were transferred to a Tal Shiar prison camp on Pictae. Following the destruction of Romulus in 2387, the Tal Shiar abandoned the planet. Yar grew old on the planet and passed away in the early 25th century. The T'nae from the alternate 2409 was the only survivor. Sela learned the truth about her mother's later life during a mission to rescue T'nae, whose presence caused temporal anomalies. (STO - Yesterday's War mission: "Survivor")
In an alternate version of this timeline, the crew of the Battleship USS Enterprise slowly became mad due to the convergence of different timelines and the conflict between Q and Trelane. This version of the crew, including Lieutenant Yar, were killed. (TNG novel: Q-Squared)
In an alternate timeline beset by the Q Continuum's temporal anomaly crisis, Warship Tasha Yar was pulled into the year 2380 of that amalgamated timeline. She joined Starfleet to help Q resolve the crisis. (ST video game: Timelines)
Borg Queen[]
In an alternate reality where the Section 31 artificial intelligence Control merged with the Borg, the Control Borg was an interstellar nation based on magnetized nanomachines. The nation's monarch was the Control Borg Queen. In the 2410s decade, Tasha Yar was the queen of the Control Borg. Her daughter Sela was a Starfleet officer and commanded the Iconian Alliance starship USS Enterprise-F following the assimilation of the galactic powers by the Control Borg. Sela tried to shoot Yar but was stopped by her personal shield. Yar replied, "Long live the queen." She was stopped from assimilating the Iconian World Heart in the Solanae Dyson Sphere by the Aetherian leader Grendat-Bex. Yar returned to her ship, the Control Borg Queen Octahedron. In aerial combat, the combined forces of the Iconian Alliance, Aetherian Concordium and Khitomer Alliance destroyed the Borg octahedron, seemingly killing Queen Tasha. (STO - Kings & Queens mission: "Situation Under Control")
Other timelines[]
In another alternate timeline in which Starfleet ceased to exist after the late 23rd century, Tasha Yar was in a romantic relationship with Ro Laren in the 2360s. (TNG - The Last Generation comic:[citation needed])
In another alternate timeline, Yar lived as an anomaly on an Earth circa 2013. This version of Yar was a mutant with telepathic ability. She was used to send the consciousness of the 21st century Kitty Pryde into Pryde's body in the past in a bid to avoid Kang. A Sentinel killed Yar, but not before she accomplished her task. (TNG comic: "Second Contact")
In an alternate reality, Yar was the tactical officer of the US Enterprise, which was under the command of Wesley Crusher, in 2380. She held the rank of lieutenant commander.
In another alternate reality, Yar was the tactical officer of the United Earth Space Probe Agency vessel Enterprise before it was captured by the Klingon Empire and became the IKS Qu'. She was killed while trying to escape from the Klingons. By 2380, Captain Picard was the only surviving member of the original crew. (TNG novel: Q & A)
