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.
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.
Edward might be extremely protective. He already has a strong urge to keep Bella safe, but with the added connection to the Joker, he'd be on high alert. He might be worried about the Joker's influence on Bella and try to keep her away from that part of her life.
She might become more protective. As Silas's sister, she would have a natural inclination to safeguard him, which could make her more assertive.
Well, Bella Swan as a SHIELD agent might bring some unique skills. Maybe her knowledge of the supernatural world in the Twilight universe could give her an edge in dealing with otherworldly threats that SHIELD sometimes encounters. She could be assigned to a special unit that focuses on such threats, using her past experiences to her advantage.
Well, one possibility could be that Bella Swan has to deal with the chaos that comes with being the Joker's daughter. Maybe she struggles to balance her normal life, like in Forks, with the dark and unpredictable world of her father. She might have some of the Joker's traits, like a wild sense of humor but also a bit of madness that she has to control.
One key element is the clash of different universes. Bella Swan comes from the relatively normal (compared to the Suicide Squad's world) world of Twilight. So, when she's thrown into the Suicide Squad's world led by the Joker, there's a big contrast in values, powers, and the general way of life. Another element is the relationship between Bella and the Joker. It could be a relationship of enmity, where the Joker sees Bella as a new plaything or an ally in some strange plan he has. Or it could be a more complex relationship where Bella tries to understand the Joker's madness and maybe even reform him. Also, the action and adventure elements are important. The Suicide Squad is known for its dangerous missions, and Bella getting involved in those adds a lot of excitement to the fanfiction.
She might be portrayed as a villain by showing her being manipulative. For example, she could use her relationship with other characters to get what she wants, like using Edward's love for her to control his actions or decisions.
Well, in some fanfictions, she might be depicted as the devil through her actions. Maybe she's shown as being manipulative, using her charm to get what she wants from others, much like how the devil is often portrayed as a tempter in traditional stories.
Klaus would probably be very intrigued by Bella. He's used to getting his way with most people, but Bella is not easily swayed. So he might start by trying to charm her, but she would be resistant. For example, he could offer her power or protection, but she would be more concerned about her own values and the people she cares about in Forks.
The story would change drastically. For starters, her relationship with Edward would be very different. Instead of being the vulnerable human he has to protect, she would be a powerful being in her own right. Their dynamic might shift from protector - protected to more of an equal partnership, or even a power struggle if their goals don't align.
