Ra's al Ghul, sometimes written Ra's al Ghul (Arabic: ?), is a DC Comics supervillain and is one of Batman's greatest enemies. His name in Arabic has been translated in the comics as "The Demon's Head" and references the name of the star Algol. Created by writer Dennis O'Neil and artist Neal Adams, he was introduced in Batman #232's "Daughter of the Demon" (June 1971). Given his high status as a supervillain, he has also come into conflict with Superman and other superheroes in the DC Universe. Ra's al Ghul has been featured in various media adaptions, most notably the 2005 Christopher Nolan film, Batman Begins, where he was portrayed by actors Liam Neeson and Ken Watanabe, the latter being a successful decoy.
