One option is that Bill Cipher is the main antagonist, while a group of Gravity Falls' minor characters band together to be the main characters. For example, the gnomes could be involved, as they have a connection to the forest where lemons might be growing. Wendy could also be part of this group, using her cool - headedness to deal with Bill's lemon - inspired mayhem. And there could be a mysterious lemon - spirit character that is also a main character, guiding the others in their fight against Bill.
Obviously, Bill Cipher himself would be a central character. He could be joined by Dipper Pines, who might be intrigued by the strange lemon - related events that Bill is causing. Mabel Pines could also be involved, perhaps using her creativity to deal with the lemon - themed chaos that Bill brings. Another possible main character could be Soos, who might have some unique insights into the whole lemon - Bill situation.
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.
Well, obviously Harry Potter himself would be a main character. He would be the one to probably first notice the strange influence of Bill Cipher. Then there could be Hermione Granger, with her intelligence, trying to figure out how to combat Bill Cipher's powers using her knowledge of magic. Ron Weasley might also be there, providing his loyalty and humor in the face of this new and terrifying threat.
Well, Bill Cipher would obviously be one of the main characters since it's about his rebirth. There might also be the characters who were associated with him in the original story, like Dipper and Mabel. They could be trying to stop him or figure out what his new plans are.
Well, Bill Cipher himself is obviously a very popular character in this type of fanfiction. He's the main attraction as people are curious about how he'd be as a human or interact with humans.
Ford Pines is another likely character. Given his knowledge of the strange and the supernatural, his encounter with Bill Cipher in a crossover could be full of tension and intellectual battles. He might try to outwit Bill using his scientific knowledge combined with his understanding of the occult.
Well, in some fanfictions, Bill might kidnap Will to gain more power. Maybe Will has some special ability or knowledge that Bill wants to use for his own evil plans.
I think Kakashi would also be a great character to pair with Bill Cipher. Kakashi is very intelligent and experienced. His encounter with Bill Cipher would be full of mind - games as he tries to figure out Bill's motives and powers while also protecting the village from Bill's chaos.
Typically, it's enthusiasts who create 'dragon bill cipher fanfiction'. These could be individuals who have a passion for creating fictional worlds. They might be inspired by other works in the fantasy or mystery genres. Maybe they were thinking about how dragons could interact with something like bills and a cipher, and then decided to put their ideas into a story. It could be someone who loves to write and wanted to explore this unique combination of elements in a fictional setting.
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.
Dipper would be a great character to pair a female Bill Cipher with. Their personalities are so different - Dipper's inquisitive and cautious nature against her more wild and unpredictable self. It could create some really interesting storylines. Mabel could also work well. Her positive and friendly attitude might be a contrast to the female Bill Cipher, leading to some fun and heart - warming interactions.
