This Batman-Batgirl storyline differs from the comic books. In previous incarnations of the story, Batman's first partner is Dick Grayson, who becomes Robin and joins Batman as his apprentice, later leaving to become Nightwing. The decision for Batgirl to be Batman's first sidekick in The Batman was due to Robin not permitted to be used in the show due to him being used in the Teen Titans animated series, which aired on Cartoon Network and due to the Bat-embargo (a restriction in place regarding usage Batman's allies and enemies in multiple animated shows based on the comics). This season also sees the destruction of Batman's original Batmobile, which is replaced by an updated version for the remainder of the series.
