Sara Lance, also known by her alter-ego White Canary, is a fictional character in The CW's Arrowverse franchise, first introduced in the 2012 pilot episode of the television series Arrow, and later starring in Legends of Tomorrow.

It's shown that five years prior to the beginning of the series, she was having a secret affair with her sister's boyfriend Oliver Queen and was with him on his family yacht when it shipwrecked.

She and Nyssa became lovers, and Sara became a deadly fighter with the League of Assassins under the name Ta-er al-Sahfer, roughly translated to "Yellow Bird" or "Canary" from Arabic.

She aids him and his colleagues Felicity Smoak, John Diggle, and Roy Harper in taking down a drug-enhanced Slade Wilson, with help from the League of Assassins, which requires Sara to return to Nanda Parbat.

Some time later, it is revealed that Thea Queen killed Sara after being drugged by her father Malcolm Merlyn as part of a plot to pit Oliver against Ra's al Ghul.

Sara briefly returns in season six when she receives a call from her sister's doppelgänger, the recently reformed criminal from Earth-2 Laurel Lance / Black Siren, who informs her that Quentin had been seriously injured in the battle against Ricardo Diaz and is in the hospital.

The doctor comes and informs everyone present that Quentin has died from lack of oxygen to his brain during surgery, leaving Sara, Laurel, Oliver, and the rest of Team Arrow devastated.

Later, as Oliver (under the direction of the FBI) announces to the world on live TV that he is the Green Arrow, before being taken to prison, Sara and Laurel mourn together over Quentin's body.

Though Sara is slow to return his feelings, Snart eventually hints at his love for her and expresses a desire to have a future with her near the end of the season after they destroy the Occulus.

Snart, however, ends up sacrificing himself to destroy the Occulus in Ray Palmer's place, and Sara kisses him for the first and final time before leaving with the rest of the team before the Vanishing Point explodes.

In the four-part crossover "Crisis on Earth-X", Sara travels to 2017 to attend the wedding of Barry Allen and Iris West, where she has a one-night stand with Supergirl's adoptive sister Alex Danvers.

In season four of Legends focuses on Sara leading the team to track down magical "fugitives" of mythology from around the timestream, with the support of Ava and the Time Bureau.

In season five, after the Time Bureau is no more, Ava is co-captain of the Waverider and helps the team track down the "encores", evil criminals returned from hell to different points on the timeline.

Sara and the Legends try to get to Gwyn Davies in New York, the person who invented time travel, in order to help them get back home.

According to Arrow executive producer Andrew Kreisberg, Sara was originally meant to be Ravager but they decided to give that role to Summer Glau's character Isabel Rochev instead.
