Arkady Duvall is an enemy of Jonah Hex and an outlaw in Batman: The Animated Series. He is also the son of Ra's al Ghul, although Ra's soon realized he was too cruel and unstable to ever take over his empire. He once attended a rich school and learned swordsmanship and later went to America and did something horrible to a woman in the east. He left to join his father Ra's al Ghul in his attempt to destroy all the railroads in America. Not caring for his father's ecological goals, Arkady was only interested in forging an empire for himself.
