Natassia "Tasha" Yar grew up avoiding the rape gangs and died at the "hands" of Armus ("Skin of Evil").

When the Enterprise-C came through a rip in time from year 2344 to year 2366, it caused a changing of history: the Klingons never became friends with the Federation and Tasha Yar never died ("Yesterday's Enterprise"). Tasha was sent through the rip to repair the original timeline along with Enterprise-c, apparently to survive and bear a daughter Sela with a Romulan in year 2344. Sela later became a Romulan operative ("Redemption", "Unification").

She has a sister Ishara Yar ("Legacy").
