Ra's al Ghul (Arabic: رأس الغول Raʾs al-Ġūl; "Ghoul's Head") is a fictional character, a supervillain who appears in comic books published by DC Comics. Besides being considered to be one of Batman's greatest enemies, given his high status as a supervillain, Ra's al Ghul has also come into conflict with Superman and other heroes in the DC Universe. He is the son of Sensei, the father of Talia al Ghul, Nyssa Raatko, and Dusan al Ghul, and the grandfather of Damian Wayne. His name in Arabic has been translated in the comics as "The Demon's Head".

Ra's al Ghul has been featured in various media adaptions, most notably Batman: The Animated Series, where he was voiced by David Warner, Batman: Arkham City, voiced by Dee Bradley Baker, the films Batman Begins and The Dark Knight Rises where he was portrayed by actor Liam Neeson, and the TV Series Arrow where he is portrayed by actor Matt Nable.

IGN's list of the Top 100 Comic Book Villains of All Time List ranked Ra's as #7.
Ra's al Ghul, literally translated from the Arabic as Head of the Demon, is an international immortal eco-terrorist and an enemy of Batman. Believing that humanity is a blight on the planet, his extremist environmentalism has led him to seek the destruction of modern society. Born centuries ago, he has sustained his life through usage of restorative Lazarus Pits. These centuries of experience have made him an incredible tactical expert and physical combatant, allowing him to establish the League of Assassins. His daughter Talia al Ghul has been romantically involved with Batman, leading to a child between the two named Damian Wayne. Ra's al Ghul was created by Dennis O'Neil and Neal Adams, first appearing in Batman #232. (1971)

Get the Ra's al Ghul mug.
The master of kicking ass. He's an evil genius and I love him. With all my heart. He's unbelievably awesome. He is just as good as Batman at hand-to-hand combat and sword fighting. What a playa!
Ra's al Ghul: Man I'm cool.
Some guy: I agree.
Ra's al Ghul: Of course you agree. If you don't I would kill and rape you.
Some guy: ...
Ra's al Ghul: Hell yeah.
