On the topic mentioned previously of Roy being linked to the "B.O.B. Entity":
From the show Twin Peaks
>Bob is an interdimensional entity from the Black Lodge, a realm which exists on an alternate plane of reality. While "possessing" humans, he commits horrible crimes to elicit pain, fear, and suffering in those around him. In a series of promotional trading cards issued for Twin Peaks, his birth date is listed as "From the beginning of time", and his "accomplishments" are listed as "I have survived as long as man has been on earth."
Not saying this is describing Roy, but it gives me the impression that his "true form" is a very old spirit as well.
