But, as the season moves forward, Gotham may pull strings behind-the-scenes to ensure another favorite villain makes their way to television.
And, now, one of the show’s executive producers is playing coy when it comes to the possible debut of Harley Quinn.
The star even teased that Barbara will have a “massive character reveal” at the end of this season, perhaps signaling the start of Harley Quinn’s reign.
And, in the past, Richards did tell CinemaBlend the villain would fit right in with Gotham’s current roster.
The regular cast features: Ben McKenzie as Detective James Gordon, Donal Logue as Harvey Bullock, David Mazouz as Bruce Wayne, Morena Baccarin as Leslie Thompkins, Sean Pertwee as Alfred, Robin Lord Taylor as Oswald Cobblepot/The Penguin, Erin Richards as Barbara Kean, Camren Bicondova as Selina Kyle/the future Catwoman, Cory Michael Smith as Edward Nygma/the future Riddler, Jessica Lucas as Tabitha Galavan, Chris Chalk as Lucius Fox, Drew Powell as Butch Gilzean, Maggie Geha as the future Poison Ivy, Michael Chiklis as Detective Nathaniel Barnes, and Benedict Samuel as Mad Hatter.
