The plot could also involve Lincoln trying to understand the chaotic nature of Bill Cipher's world. Bill might see Lincoln as an interesting plaything and start causing chaos in Lincoln's life. Lincoln then has to use his wits and the lessons he's learned from his large family to deal with Bill's antics.
Well, one possible plot could be that Lincoln, being his curious self from 'The Loud House', stumbles upon a strange dimension where Bill Cipher exists. Bill, being his mischievous self, might try to trick Lincoln into making some wild deals. Maybe Lincoln has to find a way to outwit Bill to get back home to his family.
Perhaps Lincoln is on some sort of adventure in his own world when Bill Cipher finds a way to cross over. Bill starts messing with the Loud family, and Lincoln feels responsible for stopping him. He teams up with his siblings in some creative ways to counter Bill's magic and send him back to his own realm.
Lincoln is a down - to - earth kid who values family and normalcy. Bill Cipher, on the other hand, is a chaotic and malevolent being. So, Lincoln would be constantly trying to bring order and protect what he loves, while Bill would be all about disrupting that order just for fun.
Perhaps Bill Cipher enters Will's dreams and slowly manipulates his mind. As he 'gets' Will, he starts to change Will's perception of reality. Will, being a more innocent or naive character, might not realize what's happening at first. This could lead to a story where Will has to fight against Bill's control over his mind and soul, creating a tense and psychological plot.
I'm not entirely sure specifically what that fanfiction is about. It could potentially be about Bill Cipher achieving or obtaining Will Cipher in some way, perhaps in a strange or otherworldly scenario within the context of the Gravity Falls universe. It might involve some sort of power play or a very unique plot device that only fans who have read it would know for sure.
A possible plot could be that Lincoln is kidnapped by a mysterious figure who has a vendetta against the Loud family. The kidnapper takes Lincoln to a remote location. Lincoln, being the brave character he is, tries to figure out the kidnapper's motives while also looking for an opportunity to escape. Meanwhile, his sisters and parents are following every lead they can find, from Lincoln's friends to any strange activity in town. The fanfiction could build up the tension as Lincoln tries to outwit the kidnapper and his family races against time to find him.
One idea could be Bill Cipher getting trapped in a human form and having to navigate the strange world of human emotions and social norms. It would be a comical yet thought - provoking plot as he tries to understand things like friendship and love while still having his devious nature.
One possible plot could be that Bill takes Mabel to his dimension. There, Mabel has to use her wits and creativity to outsmart Bill. Maybe she befriends some of the strange creatures in Bill's realm who help her in her escape plan.
In a fanfiction, Bill Cipher could be a hidden power that was sealed away long ago in the Naruto world. When accidentally released, he starts to reshape the world according to his own chaotic vision. Naruto, with his unwavering belief in his friends and the power of the Nine - Tails, would be the one to stand up against Bill and try to return the world to normal.
One aspect of Bill Cipher and Dipper fanfiction is the exploration of their complex relationship. Bill is often depicted as a menacing and powerful entity, while Dipper is curious yet cautious. In many fanfictions, Dipper might be lured into Bill's schemes, creating a lot of tension and drama. It's a great way to expand on the personalities and potential interactions that were only hinted at in the original show.
One great Bill Cipher fanfiction is 'The Cipher's Game'. It has an interesting plot where Bill interacts with the main character in a dream - like world filled with strange and mind - bending challenges. The author does a wonderful job of capturing Bill's chaotic and mischievous nature.
Dipper Pines could be one of the main characters. He might be the one who first discovers Bill's transformation and tries to figure out if it's a trick or if Bill is truly changing. His inquisitive nature would make him a great foil to Bill's new human self.
