The Dark Knight of Gotham City confronts a dastardly duo: Two-Face and the Riddler. Formerly District Attorney Harvey Dent, Two-Face incorrectly believes Batman caused the courtroom accident which left him disfigured on one side; he has unleashed a reign of terror on the good people of Gotham. Edward Nygma, computer-genius and former employee of millionaire Bruce Wayne, is out to get the philanthropist; as The Riddler he perfects a device for draining information from all the brains in Gotham, including Bruce Wayne’s knowledge of his other identity. Batman/Wayne is/are the love focus of Dr. Chase Meridan. Former circus acrobat Dick Grayson, his family killed by Two-Face, becomes Wayne’s ward and Batman’s new partner Robin the Boy Wonder.
