Batman has many foes, many of whom are wildly theatrical urban criminals. But Ra’s al Ghul is a Super-Villain of a different caliber. Hundreds of years old, Ra’s—which translates from Arabic as “the Demon’s Head”—is leader of the League of Assassins. He was born over 600 years ago, but thanks to repeated exposure to the mystical Lazarus Pits, he’s extended his lifespan many times over.

A dangerous idealist, Ra’s believes the perfect ecological balance can only be achieved by getting rid of a large portion of the human population. To this end, he’s orchestrated numerous attempts at genocide, bringing him into direct conflict with the Batman.

Despite his obvious enmity for Batman, Ra’s sees him as a worthy adversary. For years he tried to have Batman wed his daughter Talia. And although he learned Batman’s secret identity before their first meeting, he refuses to reveal it out of respect for the man he simply refers to as “Detective.” Now the two are bound by blood, as Bruce Wayne and Talia’s son Damian is the grandson of Ra’s al Ghul. But regardless of their familial connection, Batman knows Ra’s is never to be underestimated or trusted. He remains one of the greatest threats the DC Universe has ever known.
