 Buffy and Angel both battle the same ancient evil, a Possessor who was once Qin, First Emperor of China. As a Possessor, Qin's body loses its temperature fast and he is forced to jump from body to body through the ages, rendering him immortal. In present day Sunnydale and Los Angeles, Qin is attempting to usher in the Year of the Hot Devil and drive humans out of his dimension by resurrecting an ancient dragon frozen in ice from centuries before.
