Well, a Bella Swan and Joker fanfiction could be really interesting. It might explore a scenario where Bella, from the 'Twilight' series, somehow gets transported to the chaotic world of the Joker. Maybe she uses her own kind of 'vampire - like' calmness to deal with the Joker's madness.
Obviously, Bella and the Joker are the main characters. Bella could be a completely original character created for this fanfiction, or she could be a reimagined version of an existing character from another story. The Joker, of course, is the well - known villain from the Batman universe.
One common theme is the clash of different worlds. Bella comes from a more supernatural - tinged world in Twilight, and the Joker is from the gritty, crime - filled Gotham. So, the fanfictions often explore how these two disparate worlds collide when the characters meet.
There's also a possibility that some of the more morally grey characters in Gotham, like Catwoman, could be Bella's allies. Catwoman has her own code of ethics, and she might relate to Bella's struggle between good and evil. They could work together in certain situations, especially if there are mutual benefits involved.
It could work by focusing on their personalities. Bella is often seen as a bit of an outcast in her own world, and the Joker is the ultimate outcast in Gotham. So, they could bond over that feeling of not belonging.
One common theme is the clash of two different worlds. Bella often represents a more innocent or 'normal' world while the Joker is all about chaos and anarchy. Another theme is the idea of transformation. Bella might be changed by her encounter with the Joker, or vice versa.
Perhaps in the fanfiction, Bella is an artist who is intrigued by the Joker's chaotic and dark aesthetic. She tries to capture his essence in her art, but this draws her too close to him. As a result, she finds herself in the middle of the Joker's battles with Batman, and she has to decide whether to side with the 'good' or be swayed by the Joker's allure.
Well, she might be very protective. Since Joker is often in chaotic and dangerous situations, she could be constantly worried about his well - being and try to shield him from harm in the fanfiction world.
One common theme is the idea of opposites attracting. Bella and Joker are very different characters, so this theme of how their differences complement each other is often explored.
In this fanfiction, Bella's vampiric allure might attract the Joker in a different way than he's used to. He could start to see her as a new kind of plaything. Bella, however, might see the Joker as a way to break free from the monotony of her vampire existence. Their interactions would be filled with tension, as Bella tries to keep her vampire identity a secret while the Joker is constantly probing for more information about her.
