JF Sebastian Genetic Design (Grey)

J. F. Sebastian is a genetic designer, working for Tyrell/Rosen. He is stuck on Earth due to his medical condition, “Methuselah Syndrome,” which also gives him something in common with the Nexus 6 Replicants, namely accelerated aging. With the Bradbury Building all to himself, he makes the most of his gifts, even making his own Toy-friends.
