Sara Lance based on Black Canary
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. The character is an original character to the television series, created by Greg Berlanti, Marc Guggenheim and Andrew Kreisberg, but incorporates character and plot elements of the DC Comics character Black Canary. Sara was portrayed by Jacqueline MacInnes Wood in the pilot episode, but subsequently by Caity Lotz.
Sara initially goes by the moniker of The Canary, a translation of her Arabic League of Assassins name الطائر الصافر (Ta-er al-Sahfer). She later adopts the code name of White Canary before joining the Legends of Tomorrow, and eventually becoming the captain of the team.
Lotz has appeared as Sara Lance and her superhero persona in crossovers on The Flash, Supergirl and Batwoman, all set within the Arrowverse. The character has also appeared in a digital comic book series.
