Chosen answer: Killer BOB is a demonic entity that emanates from a realm of pure evil known as the Black Lodge, a place that exists on an alternate plane of reality. BOB feeds on human pain and suffering and can travel on earth by possessing human beings and also as an owl. While possessing humans, he commits horrible acts to elicit pain, fear, and suffering from those who are around him, using that as nourishment. BOB possesses Leland Palmer, later forcing him to abuse, rape, and eventually murder his own daughter, Laura, and later to commit suicide.
