A Gravity Falls fanfic I've had on the back-burner involves a man named Fell Williams responsible for most of the conflict. Fell is a greedy hunter of the paranormal who makes sure he stays employed by taking advantage of the monsters he hunts and the general public's lack of knowledge on the subject. Just some of his crimes include: * Feeding people human flesh so they turn into wendigos for him to hunt. * Killing the head of a vampire clan but letting the others go, relying on the resulting power vacuum to increase his business. * Capturing ghosts and, instead of excorcizing them, enslaving them and forcing them to haunt other houses so the residents will hire him. * Framing his own father, another paranormal hunter, as a fraud to increase his own reputation and garner sympathy. * Abducting Dipper and trying to murder his family, children included. Thing is, Fell actually dies rather early in the story, just a few chapters in. The rest of the story is about Dipper, Mabel, and their respective families undoing all the damage he's done. As such, Fell Williams remains the primary antagonist even long after his own death. Would the idea of a man being so evil that he continues to influence the story from beyond the grave sound like an interesting idea? Or does it just come off as adding a gimmick for the sake of a gimmick?
