Katie Cassidy Rogers has been a mainstay of the Arrowverse since Arrow first began in 2012. However, her original incarnation, from Earth-1, has recently been confirmed by Arrow co-creator Marc Guggenheim to be making a comeback in the upcoming Crisis on Infinite Earths.

Dinah Laurel Lance of Earth-1 first appeared in the first season of Arrow as the ex-girlfriend of Oliver Queen after his supposed death. Over the course of the show’s first five seasons, Laurel became the vigilante known as the Black Canary and joined Team Arrow to fight crime in Star City before being murdered by the villainous Damien Darhk.
Earth-2 Laurel Lance, formerly known as Black Siren and currently known as Black Canary, first appeared in Arrowverse series The Flash during the latter half of Season 2. She was a part of villainous speedster Zoom’s metahuman army and appeared shortly after her Earth-1 counterpart was murdered by Darhk in Arrow’s fourth season.
Laurel is currently part of Team Arrow aiding Oliver Queen in his mission for The Monitor to prevent the upcoming Crisis from occurring whilst also dealing with the loss of her homeworld Earth-2.
A third Laurel Lance, from the Nazi-ruled Earth-X, made a one-episode appearance in The Flash Season 4 under the moniker Siren-X.
However, it seems as though Earth-1 Laurel is set to return to the Arrowverse in the upcoming Crisis on Infinite Earths. Even though how she returns is still being kept a mystery, with the inclusion of the Legends of Tomorrow and their ally Jonah Hex, it stands to reason that time-travel will be included at some point in the five episodes.
Earth-1 Laurel Lance is the only of the three known Laurel Lances to not be a metahuman with Black Canary’s signature Canary Cry.
Crisis on Infinite Earths is set over five episodes of Arrow, The Flash, Supergirl, DC’s Legends of Tomorrow and Batwoman beginning in December 2019 and concluding in January 2020.
