Character development is key. Dipper might start out as a bit naive about Bill's true nature but as the story progresses, he could become more cynical or more determined. Bill, on the other hand, could show some unexpected sides, like a moment of vulnerability or a different motive than just chaos. This makes the characters feel more real and engaging. Also, a great fanfic in this genre will often have a unique take on the Gravity Falls universe. Maybe it explores a part of the town that was never shown in the show or has a different set of rules for magic. All of these elements combined can make for an excellent Bill Cipher x Dipper fanfic.
