Main article: List of villains in The Batman
Batman, Robin and Batgirl have faced a slew of evil doers from the classic Batman Rogue's Gallery. Using some of the comic's most famous villains, The Batman's writers have created a unique spin on some classic characters (Poison Ivy’s origins, for instance), while introducing some of their own non-comic-book-based baddies. Some main villains of the comic book, such as Two-Face, Scarecrow, and Ra's al Ghul, are not included in the show. This was due to an agreement with Warner Bros. not to use them because of the movies Batman Begins and The Dark Knight.
