One possible scenario in this fanfiction could be Joker and Harley Quinn finding themselves in the world of Twilight. Maybe they would disrupt the vampire - human dynamics there. Joker might see the vampires as new playthings, while Harley could be intrigued by the idea of a different kind of 'love' like the one between Bella and Edward. But they would also bring their own brand of chaos.
Joker would probably see the Twilight world as a new playground. He might try to mess with the Cullens, seeing them as too 'perfect' and in need of some chaos. Harley, on the other hand, could be fascinated by the idea of eternal love in the Twilight series. She might even try to get involved in the relationships, perhaps causing some jealousy or misunderstandings.
I really like the fanfiction 'The Dark Romance of Joker and Harley'. It has a great take on their relationship, showing how they both feed off each other's madness. 'Harley Quinn's Revenge' is also good. Here, Harley decides to take revenge on the Joker for all the wrongs he has done to her. It's an exciting read as it shows a different side of Harley. Then there's 'Joker's Secret Plan' which involves a lot of mind - games between the two characters, making it a very engaging fanfiction.
One great 'Harley Quinn Joker Fanfiction' is 'Mad Love Reimagined'. It delves deeper into the complex relationship between Harley and Joker, exploring Harley's psyche as she falls deeper into the Joker's chaotic world. The writing style is vivid and really brings out the twisted nature of their relationship.
Harley's character could develop in many ways. She might become more protective and motherly, which is a big change from her usually wild and carefree self. This new - found sense of responsibility could make her question her relationship with Joker and the life of crime they lead.
They're popular because their relationship is so complex and intense. The Joker is this chaotic, unpredictable character and Harley is completely devoted to him, despite his abuse. It makes for a really interesting dynamic to explore in fanfiction.
In a fanfiction, Harley Quinn could form an unexpected alliance with Batman against the Joker. She realizes that the Joker's madness is too much and she wants out. Batman, seeing an opportunity to use Harley's knowledge of the Joker's operations, agrees to protect her if she helps him take down the Joker. This would be a huge shift in the typical relationships between these characters.
One great fanfiction could be about Harley Quinn finally breaking free from the Joker's control. In this story, Batman might be the one to help her see the truth. He could offer her a chance at redemption and a new life away from crime. Harley would then have to struggle with her feelings for both the Joker and the idea of a new life without him. This could lead to some intense and emotional scenes between the three characters.
The fanfiction about Harley Quinn and Joker's 'hurt' relationship often explores the dark and complex nature of their bond. It might show how their toxic relationship affects them and those around them. For example, in some stories, Harley's loyalty to Joker despite his abuse is a central theme, highlighting the psychological hold he has on her.
