Batman faces Two-Face -- formerly Bruce Wayne's friend, District Attorney Harvey Dent -- in stories from the 1940s to today. Once, he was Gotham City's crusading District Attorney Harvey Dent. But when a criminal threw acid in his face, disfiguring his left side, Dent lost his grip on sanity and became the villain known as Two-Face. Making every decision with the help of a two-sided coin -- one scarred, the other undamaged -- Two-Face became one of Batman's greatest adversaries. Every step of the way, Batman has tried to help his friend leave the path of evil and remember that he was once a force for justice. These are the best of Batman's battles with Two-Face, including work by Batman creator Bob Kane, as well as writer Dennis O'Neil, artist Neal Adams, animation legend Bruce Timm and many others.
