Fan Casting Ra's Al Ghul in Batman: The Brave and the Bold

An immortal assassin who is hundreds of years old, the leader and creator of the League of Assassins, Talia's father, Damian's grandfather, and Bruce's mentor. Ra's is a megalomaniac who plans to destroy Gotham with his army of Man-Bats and then dominate and reshape the world to his will. Whenever he dies, he is resurrected by the Lazarus Pit, and the constant use of it has driven him increasingly insane and given him supernatural abilities. Ra's is a cold-blooded killer and a master of the martial arts.
