Batman's Rogue's - R'as ahl Ghul

The last of this set is one of The Dark Knights most prominent adversaries, mostly because the two are somewhat similar in many ways. That villian is R'as ahl Ghul, the immortal bio terrorist who wishes to save the world, by eliminating every single person on the planet. His appearence in the movies certainly helped dictate this, especially since he trained Bruce Wayne personally so that he could continue his work. He really is something else, I gotta say.
