Fanfiction about Harley Quinn and Batman in Arkham Knight: What are some interesting plot ideas?

One common theme is Harley Quinn's relationship with the Joker. Even in the Arkham Knight setting, her past with him often plays a big role in the fanfictions. Another theme is her interactions with Batman. Since they are adversaries in the game, fanfictions might explore different aspects of their confrontations or even rare moments of cooperation.

One idea could be Harley Quinn trying to reform herself and Batman being reluctantly drawn into helping her. Maybe she has some crucial information about a new villain in Gotham and in exchange for her safety and a chance at a new life, she offers to work with Batman.

One plot idea could be that Harley Quinn is being hunted by a new super - villain in Gotham who wants to use her knowledge of the Joker's operations against him. Batman, despite their past differences, decides to save Harley because he realizes she could be a key in preventing a much larger threat to the city. He manages to rescue her from a dangerous trap set by the new villain and in the process, Harley starts to see Batman in a new light, not just as an enemy but as someone who actually cares about her well - being.

One idea could be that Harley Quinn tries to reform herself to be worthy of Batman's trust. Maybe she starts secretly helping Batman take down other villains in Gotham. Another could be a situation where they are forced to team up against a common, extremely powerful enemy, like a new supervillain who has a plan to destroy Gotham. And a third idea is that Harley Quinn has a change of heart about the Joker after seeing how Batman is constantly fighting for good, and she begins to see Batman in a new light, leading to a complex relationship between them.

Well, a great plot idea might be delving deeper into the relationship between Batman and his rogues gallery in the aftermath. For example, how the villains react to Batman's continued presence or absence. Some might see it as an opportunity to take over Gotham, while others might be secretly glad he's still around to keep a certain order. Also, exploring the technological fallout. With all the advanced tech used during Arkham Knight, there could be some unforeseen consequences like tech falling into the wrong hands or new, unexpected uses for it.

One idea could be exploring how the Knightfall event affects Batman's relationships with his allies in the Arkham Knight universe. Maybe some of them start to question his methods more deeply.

One interesting plot idea could be a fanfiction where the Joker somehow comes back to life in Arkham Knight. Maybe he was only in a coma and wakes up with a new, even more deranged plan to take over Gotham. He could start by manipulating the inmates in Arkham again, creating chaos from within the asylum.

In this fanfiction, it could be interesting if Catwoman discovers a secret about the Arkham Knight that Batman has overlooked. She could use this knowledge to her advantage, either to make a deal with the Arkham Knight or to help Batman. For example, she might find out that the Arkham Knight has a weakness related to a certain location in Gotham that was important to his past. Catwoman could then lead Batman there to take down the Arkham Knight.

The Harley Quinn DLC story in Batman Arkham City often focuses on Harley's own adventures and misadventures within Arkham City. It shows her loyalty to the Joker and her attempts to carry out his plans in her own chaotic way.

One key event is her attempts to carry out the Joker's unfinished plans. She also has a big showdown with Batman at her lair. Another event is when she teams up with other villains to try and take over Gotham.
