According to executive producer John Stephens, the final season will take influence from the comic book arcs No Man's Land, Zero Year, and at least one other unspecified storyline that he says "if I tell you what it is it really does spoil the story."
Sharing a common goal, Bruce Wayne, Alfred Pennyworth, and Lucius Fox will become the "strongest team" of the season, with Alfred training Bruce and Lucius providing him with gadgets. This will propel Bruce's transformation into Batman. Bruce will infiltrate various gangs that have taken control of the city, adopting different disguises in the process.
Leslie Tompkins will go through a radical change this season, while Edward Nygma will first appear living in a public library, while naked, mumbling to himself, and covered in riddle-themed tattooes.
