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 being used in the "Teen Titans" animated series, which aired on Cartoon Network. This season also sees the destruction of Batman's original Batmobile, which is replaced by an updated version in later episodes.
