Fan Casting Greater-Scope Villain in Sort by Tropes

A Greater-Scope Villain is a threat/villainous presence that's more dangerous, affects more people, or is more significant than the story's current Big Bad in the setting as a whole, but isn't causing the conflict of the immediate story (and may have little to do with it at all). While the Big Bad is directly responsible for the current story — the Big Bad is the villain whom the heroes are attempting to defeat — a Greater-Scope Villain isn't a major force in the plot, only a major force in the background.
