Roy Batty, model number N6MAA10816, is the leader of the renegade Nexus-6 replicants and the main antagonist of Blade Runner. He is very intelligent, fast, and skilled at combat, and yet still learning how to deal with developing emotions. He blew a few of his fellow replicants on what is inevitably a fruitless search for more life. As hope slowly fades away and his friends are eliminated one by one, it is his experience that brings up the question of "What is human?"
