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.
She could be a complex character. Maybe she has her own dark past that influences how she raises Joker. For example, if she had a difficult childhood herself, it might make her either over - indulgent or overly strict with Joker. In the fanfiction, she might also have some unique skills or knowledge that she passes on to Joker, like a special way of thinking or a particular skill in surviving in Gotham's underworld.
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.
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.
Her presence can introduce a whole new layer of backstory. For instance, if the fanfiction focuses on Joker's origin, Bella's relationship with him can be a key factor in shaping who he becomes. It could be that her actions or inactions lead to his transformation into the Joker.
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.
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.
There's a fanfiction titled 'Bella and the Joker's Unlikely Alliance'. In this story, Bella's unique personality somehow catches the Joker's attention, and they end up in a strange alliance. It delves deep into their complex relationship, showing how two very different characters can be drawn together. The author does a great job of creating a believable scenario where they have to rely on each other in a rather chaotic world they find themselves in.
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.
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's hard to define the exact characteristics without having a lot of examples. But generally, it might involve the character 'joker' in some sort of uncharacteristic or forced situation, perhaps with a 'lemon' aspect which could imply some sort of romantic or sensual undertone in a rather forced way within the context of the fan - created story.
