The following is a list of characters that have appeared in the television series The Batman, which ran from September 11, 2004 to March 22, 2008. The animation style bears a strong resemblance to that of Jackie Chan Adventures, since Jeff Matsuda was the chief character designer for both shows. Many of the supervillains who appear in the series (especially in their designs), like the characters Joker, Penguin and Riddler, are very different from those of their comic counterparts. While many characters adapted from the mainstream DC comics appear, some of them only appeared in the show's tie-in comic called The Batman Strikes. Characters that were planned for a guest appearance but ultimately did not appear were Wonder Woman,[1] Bizarro,[1] Vigilante,[2] and Owlman.[3]
