Ra's al Ghul

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.
