Technically, Kate Kane wasn’t the only character to adopt the Batwoman persona in DC’s comic book universe.
Based on the characters from DC, Batwoman is from Berlanti Productions in association with Warner Bros. Television with executive producers Greg Berlanti, Caroline Dries, Geoff Johns, and Sarah Schechter.
Almost 50 years before Kate debuted in 2005, Kathy Kane became the first superhero to use this alias in 1956 during the Silver Age.
Season 2 is still expected for a January 2021 premiere date.
