The series is based on the DC Comics character Kate Kane / Batwoman, a costumed vigilante created by Geoff Johns, Grant Morrison, Greg Rucka, Mark Waid, and Keith Giffen.

Ruby Rose stars as Kate, and is joined by main cast members Rachel Skarsten, Meagan Tandy, Nicole Kang, Camrus Johnson, Elizabeth Anweis and Dougray Scott.

Batwoman was picked up for a full season by The CW in October 2019, and filming took place primarily in Vancouver, British Columbia.

Two are Sara Lance, Paragon of Destiny and Kara Danvers, Paragon of Hope but, to find two more, Clark Kent, Lois Lane, and Iris West-Allen must locate a Superman who has suffered "more than any mortal man" while Kate and Kara search for the "Bat of the Future", complicated by Lex Luthor stealing the Book in order to kill Supermen across the multiverse.

Elsewhere, Sara, Barry Allen, Mia Smoak, and John Constantine take Oliver's body to a Lazarus Pit to resurrect him, but it fails.

The series, said to only be a "script-development deal", was written by Caroline Dries, who would also serve as an executive producer with Greg Berlanti, Sarah Schecter, and the character's co-creator Geoff Johns.
