Well, one possibility is that Bakugou is initially frustrated with the hero society in the fanfic. Maybe he feels overlooked or misunderstood. The League of Villains could approach him, promising a place where he can use his power more freely without the restrictions of the hero rules. And he might be tempted by their offer, leading to his joining.
Overall, 'A Mere Cypher' is a novel that combines mystery and drama. It keeps you guessing with its plot twists and develops characters that you can really connect with. There are layers of subplots that add depth to the story.
One popular 'bill cypher fanfic' might be those that explore his backstory in the Gravity Falls universe. Maybe a fanfic where he forms an unexpected alliance with one of the main characters.
One interesting storyline could be exploring the backstories of the League of Villains members in more depth. For example, delving into how Tomura Shigaraki became the way he is. Maybe he had a tragic past that led him to embrace villainy. Another could be a story where the League of Villains teams up with an unexpected group for a common goal, like a group of anti - hero vigilantes. It would create a lot of moral and ethical dilemmas for both sides.
His aggression might become more unhinged. Without the moral compass of the hero side, he could be more willing to use excessive force. He'd still be competitive, but now it would be against heroes instead of his fellow hero trainees.
Tomura Shigaraki is a very popular character to write about. His complex personality and his connection to All For One make him an interesting subject. His journey from a seemingly lost and angry young man to a powerful villain leader has a lot of potential for exploration. Dabi is also quite popular. His mysterious past and his relationship with the Todoroki family add depth to his character. Writers can play with the idea of his motives and what he really wants out of his villainous actions.
Another possibility is that some of the other supernatural beings in Gravity Falls could be the antagonists. They might see Dipper's association with Bill, even as a human, as a threat to the balance in the town. For example, the gnomes or the manotaurs could oppose their friendship and try to drive them apart, seeing Bill as a potential source of chaos no matter his form.
First, you should really study Bill Cipher's character from Gravity Falls. Know his motives, his powers, and his personality traits. Then, come up with an interesting concept. It could be something like 'What if Bill Cipher landed in a modern - day city?'.
One possible plot could be that Bill Cypher, in human form, befriends Dipper while hiding his true chaotic nature. As they get closer, Dipper starts to notice strange things about his new friend. Eventually, Bill reveals his true self but by then Dipper has grown to understand him a bit and tries to find a way to either change Bill or at least keep his chaos in check.
😋I recommend the following novels to you:
"The Unparalleled Prince's Defiant Wife"
This was an Eastern fantasy romance novel. The main character was a top-notch assassin from the modern era. She transmigrated to the Southern Cloud Nation and became a good-for-nothing ugly girl. However, her strength was that of a genius all-elemental Summoner. She appeared as a black-bellied and evil person, so it was not difficult for her to be a villain. At the same time, there was also a useless prince from the Feng Prince residence who was pestering her endlessly. The entire plot was very subversive. I hope you like this fairy's recommendation.
