The tension between the nonhuman substance and the human appearance—or even human ambitions—of androids is the dramatic impetus behind most of their fictional depictions. Some android heroes seek, like Pinocchio, to become human, as in the film "Bicentennial Man", or Data in "". Others, as in the film "Westworld", rebel against abuse by careless humans. Android hunter Deckard in "Do Androids Dream of Electric Sheep?" and its film adaptation "Blade Runner" discovers that his targets appear to be, in some ways, more "human" than he is. Android stories, therefore, are not essentially stories "about" androids; they are stories about the human condition and what it means to be human.
