Despite being a main character in the original series, he has a decidedly small role in the comic. Billy's hourglass was possibly the most complicated and confusing hourglass Grim had ever seen. Grim notes that it was somehow tied with Mandy's, and that Billy would either die shortly before or after she did. Though Billy apparently dies at a young age, possibly due to his own stupidity (the original fanfiction mentions that he is killed in an explosion caused by him lighting a fart at a gas station), he proves to be too much of an annoyance for either Heaven or Hell, leaving him a wandering spirit on Earth. At this time, Billy whereabouts are unknown and the possibility of another appearance has not been ruled out.
