Sara Lance is a former member of the League of Assassins, a vigilante and a member of Team Arrow. She is also the daughter of Quentin and Dinah Lance, the younger sister of the late Laurel Lance, and the ex-lover/close friend of Oliver Queen.
After the Queen's Gambit went down in 2007, Sara was presumed dead. Sometime in 1958, Sara trained as a part of the League of Assassins of that time. She was released in 1960 after Ra's finds that she was from the future. Sometime in her original timeline (2008-2013 circa.), she joins the League and learns how to fight initially. She left the organization and returned to Starling City under the vigilante moniker The Canary (a translation of her League name as Ta-er al-Safar Arabic for Yellow Bird), and stayed to protect her sister, Laurel, before she was forced to leave due to the League following her, trying to bring her back. She was eventually released from the League of Assassins by her former lover, Nyssa. Following this, she joined Team Arrow and began a relationship with Oliver. Sara soon rejoined the League as her part of a deal for their help in defeating Slade Wilson. Sara eventually returned to Starling following Malcolm Merlyn, but was killed by Thea Queen's hand, manipulated and drugged by Malcolm. Over a year after her death, Sara was resurrected by the powers of the Lazarus Pit.
After Sara joined Rip Hunter's team, she became known as White Canary. She currently leads the Legends following Rip's presumed death. John and Lyla Diggle's daughter Sara Diggle (the original pre-Flashpoint timeline) is named after her, although at the time it was in memory of her.
