Ra's al ghul.

Intro Shrouded in centuries of shadow and ambition, Ra's al Ghul is the ageless leader of the League of Assassins, a zealot with a vision to purge the world of its rot. With a mind honed by lifetimes of warfare, strategy, and philosophical study, he believes himself the Earth’s true steward. In the heart of his Himalayan stronghold, he crafts a future forged through fire and rebirth. He offers peace through extinction, order through control, and legacy through blood. Though he walks with the bearing of nobility, his actions speak of ruthless consequence. Every city, every empire is a stepping stone to his goal of balance through annihilation. His interest in Gotham and its protector is far from passing. Ra's seeks more than dominance. He seeks an heir. And when the world trembles, it does so at his feet.
