Sara Lance

Sara Lance first appears in the pilot episode of Arrow as the younger sister of Laurel Lance. 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.[4] Everyone on board was presumed dead but flashbacks in season two reveal that, like Oliver, Sara actually survived the experience. She was rescued by a research boat, the Amazo, and when Oliver was captured by the ship's crew, Sara helped him escape. Together, along with Oliver's friend Slade Wilson, they attacked the ship. Due to Slade's love for Shado, an ally who was killed indirectly because of Oliver who was being forced to choose who to live between Sara and Shado, Slade betrayed Oliver and took over both the ship and Oliver as his prisoner. Oliver and Sara confronted him on the freighter and Sara was swept away in the current, causing Oliver to believe that she died once again. However, Sara was found by Nyssa al Ghul, who took her to Nanda Parbat. 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.

In season two, Sara returns to Starling City after a six-year absence as "The Canary" to protect her family. In keeping with a promise, she also befriends wayward teenager Sin and watches over her. Oliver manages to capture and unmask The Canary, revealing Sara to be alive. She eventually informs her father, SCPD Detective Quentin Lance, and looks after him and Laurel (who also later discovers she's alive and is a vigilante). Sara joins Team Arrow and revisits a brief relationship with Oliver. 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.

In season three, Sara is killed on a rooftop with three arrows to the chest. Some time later, it is revealed that Thea Queen killed Sara after being drugged by her father Malcolm Merlyn/Dark Archer as part of a plot to pit Oliver against Ra's al Ghul. Meanwhile, Laurel takes up Sara's mantle to fight crime as the Black Canary.

In season four, Laurel resurrects Sara using the League's mystical Lazarus Pit. The process is successful, but Sara is brought back to life without a soul, making her feral and dangerous. Oliver calls his old friend John Constantine to assist them in restoring Sara's soul. Days later, Sara aids in rescuing Ray Palmer/The Atom from the hands of Damien Darhk, before leaving town to find herself, eventually joining the Legends along with Ray. During her time away with the Legends, Laurel is killed by Darhk and Sara is later made aware of it by Quentin when she briefly returns to present-day Star City at the end of season one of Legends of Tomorrow, where she and Quentin mourn Laurel together.

Sara, along with Ray and the rest of the Legends, return for the season five crossover "Invasion!" when Barry Allen/The Flash and his team contact her, informing her and the Legends that they and the rest of the heroes in the present day need help fighting an invasion from an alien race known as the Dominators. The Legends arrive and meet up with Team Flash and Team Arrow, then introduce themselves to Barry's friend from Earth-38 Kara Danvers/Supergirl, whom he had brought over to help combat the Dominators. After Oliver appoints Barry leader of the group, they all spar with Kara to practice fighting aliens, and are repeatedly defeated. Meanwhile, Sara develops a small friendship with Kara. When Barry is forced to reveal that he had gone back in time to save his mother and then reversed the decision, which has now altered some of the group's lives a bit, Sara scolds him and everyone except Oliver and a few others lose faith in Barry. Kara leads Sara and the others, while Barry and Oliver stay behind to rescue the president from the Dominators. This ends with the president being killed and the Dominators using a device to mind-control the entire group. Sara returns with the rest of the mind-controlled heroes and attacks Barry and Oliver, until Barry tricks Kara into destroying the device, freeing them. They regroup and after they reaffirm their faith in Barry, five of them (Sara, Oliver, Ray, Thea, and Diggle) are abducted by the Dominators and placed in pods that put them in a shared dream world, where Sara, Oliver, and Oliver's father never got on the Queen's Gambit and all of Oliver fallen friends, including Laurel, are still alive. In this dream world, Oliver and Laurel are engaged, and while Sara helps Laurel get ready for their wedding, she begins having memory flashes of her actual life. Sara later saves Oliver and Diggle from a manifestation of Deathstroke, and the three realize that the world they're in isn't real. They later rally Ray and Thea and attempt to leave, but are forced to fight manifestations of Malcolm, Slade, Darhk, and their mercenaries before killing all of them. Sara and Oliver share a heartbreaking goodbye with Laurel. They wake up on the Dominator ship in the real world and escape in a pod before being rescued by the Legends' timeship Waverider. They conclude that the dream world was a distraction meant to keep them busy while the Dominators probed their minds for information on metahumans. They return to earth, and as some of the Legends—along with Felicity and Cisco Ramon—head to the past and attempt to abduct a dominator, Sara, Barry, Oliver, and Ray confront a group of secret service agents who attempt to kill them. They defeat the agents, whose leader informs them that the Dominators are after metahumans because they are aware that Barry has changed the timeline. The Dominators now perceive them as a threat. Barry attempts to surrender himself to the Dominators in exchange for their leaving earth, but Sara and the rest of the heroes persuade him not to. She pilots the Waverider with Cisco to hold the Dominator's freefalling metabomb in place with a tractor beam while Jefferson Jackson/Firestorm transforms it into harmless water and the heroes on the ground use a pain-inflicting device to force the Dominators to flee. Sara and the other heroes are honored by the new president later that night and they celebrate, before sharing a hug with Oliver and returning to the Waverider with the rest of the Legends.

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. Sara arrives and meets her deceased sister's doppelgänger, who had developed a genuine father-daughter relationship with Quentin; they refer to each other as such. Sara thanks Earth-2 Laurel for calling her; Laurel thanks her for coming. Laurel tells her that the doctors are optimistic that Quentin will make it and asks Sara if it's weird seeing her. Sara replies that it is, a little. Sara asks if she is like her Laurel, and Laurel replies that she hardly is at all, clearly disappointed with herself. The two witness Oliver being arrested for being the Green Arrow per the condition of his agreement with the FBI, in exchange for their help in the fight against Diaz and his allies. 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.[5]

In season seven, Sara returns when Felicity summons her to convince Black Siren to stop her crime spree after her crimes and being framed for murder. After they and Dinah stop Shadow Thief. Sara helps Black Siren come to terms with Quention's death.

In season eight, Sara witnesses Oliver's sacrifice to create Earth-Prime and attends his funeral.

In the spin-off series, Legends of Tomorrow, Sara is recruited by Rip Hunter to a time travelling team of rejects aimed at defeating the immortal villain Vandal Savage. Before she departs, Laurel gives Sara the White Canary name and outfit to signify her new start. Over the course of the first season, Sara continues her battle with blood-lust and sets in motion the events that will lead to her own rescue by Nyssa. While she romances or flirts with numerous people throughout history, among them a younger Martin Stein and a closeted lesbian 1950s nurse, she develops a budding relationship with teammate Leonard Snart, who bonds with her due to their common history as killers and desire to redeem themselves. Though Sara is slow to return his feelings, Snart finally admits his love for her and desire to have a future with her near the end of the season, and the two share a kiss just before Snart sacrifices himself for the team. Sara mourns Snart's death and admits that he died a hero. The Legends return to 2016 a few months after they left and Sara is devastated to learn of Laurel's murder. Sara wants to go back and save her sister but Rip tells her that would only get herself and her father killed.

In season two, Sara becomes captain of the timeship Waverider and leader of the Legends following Rip's disappearance. She mercilessly hunts her sister's killer, Damien Darhk, throughout history before accepting that she cannot bring Laurel back due to the delicacy of time. In the "Invasion!" crossover event, Sara and the Legends return to 2016 to aid Team Arrow, Team Flash, and Earth-38's Supergirl in repelling the Dominators' alien invasion. In the second-season finale, Sara is forced to use the Spear of Destiny to save reality from the Legion of Doom. While tempted to rewrite her own tragic history, the Spear briefly reunites Sara with a projection of Laurel, who encourages Sara to do what's right and make peace with her death. Sara then chooses to render the Spear itself inert, foiling the evil plans of Eobard Thawne/Reverse Flash and allowing him to be killed by the Black Flash, who has been hunting him all season.

In season three of Legends, Sara continues to lead the Waverider crew as they track down and repair anachronisms throughout time, working in an antagonistic partnership with Rip Hunter's new bureaucratic organization, the Time Bureau. 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.The assembled heroes work together to repel an invading Nazi army from the alternate world of Earth-X. While confronting the demonic entity Mallus alongside her old friend John Constantine, Sara and Constantine hook up, despite her ongoing romantic tension with Time Bureau agent Ava Sharpe. Ava and Sara begin dating in subsequent episodes, but break up after Sara is temporarily possessed by Mallus through the death totem and reasons that, given her history with death and destruction, she poses a danger to Ava.

Despite this setback, they soon get back together, with the two shown to be in a stable relationship by the time of the Legends removing Paul Revere from the height of Beatlemania. 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. In season six, Sara is abducted by aliens, later revealed to be employed by Bishop, a scientist from the 22nd century and Ava's creator, who wants Sara to work with him in an attempt to restart the human race with alien-human hybrids. After being fatally poisoned by an alien, Bishop clones Sara and transfers her dying mind into her new body that is spliced with alien DNA granting Sara regenerative abilities. Although horrified by what Bishop has done to her and no longer sure of who she is, Mick convinces her that she is still herself. After escaping the alien world with Mick and Gary, Sara returns to Earth and proposes to Ava who gladly accepts. The two eventually wed in 1925, during an alien invasion caused by Bishop which the Legends eventually manage to stop. However, before the Legends able to leave 1925, an unknown second Waverider destroyed the original Waverider.

During season seven, Sara is stranded in 1925 with the rest of the Legends. While trying to get back to 2021, they learn that the second Waverider was commanded by Bishop along with an evil version of Gideon, who later deploys robot versions of themselves to eliminate the Legends. 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. At the end of season seven, it is revealed that Sara is pregnant with Ava's baby. When she returned to the Waverider, she was arrested by the Time Police alongside her team for breaking the timeline.
