One good 'Joker Harley Quinn OC fanfiction' could be one where the OC is a new villain in Gotham who tries to disrupt the relationship between Joker and Harley Quinn. Maybe they start by causing misunderstandings between them, like forging messages from Harley to Joker saying she's leaving him for someone else. This could lead to a whole new dynamic where Joker is on a rampage looking for Harley, while Harley is confused as to why Joker suddenly turned on her.
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.
To write a 'Joker Harley Quinn OC fanfiction', start with research. Watch all the Batman movies and shows that feature Joker and Harley Quinn to really understand their characters. When creating your OC, give them unique traits that will make them stand out. For the plot, consider starting with a bang. Maybe your OC witnesses a major event between Joker and Harley, like a big fight, and that's what draws them into the story. As you write, make sure to keep the dialogue in - character for both Joker and Harley Quinn, and show how your OC changes and grows throughout the story.
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.
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.
