Ra's al Ghul, sometimes written Rā's al Ghū (voiced by David Warner) is a DC Comics supervillain and an enemy of Batman. His name is Arabic for "the ghoul's head" (the Demon's Head, see Algol). Created by writer Dennis O'Neil and artist Neal Adams, he was introduced in Batman #232's "Daughter of the Demon" (June 1971). He has also come into conflict with Superman and other DC Comics superheroes.
Little is known of the early years of the nearly immortal Ra's, but it is accepted that he has lived for many centuries due to the Lazarus Pits' mysterious brews that restore his youth. A brilliant master of strategy and organization, Ra's al Ghul's goal is to save the Earth from ecological devastation by destroying most of its population. He recognizes Batman as both a worthy foe and a possible ally--except that Batman cannot accept his dystopian worldview. Batman also shares a love-hate relationship with Ra's daughter, the beautiful Talia. Ra's also commands a legion of followers dedicated to bringing his version of an earthly paradise to fruition.
