What could be the plot of a 'Catwoman whips Batman' fanfic?

I'm not sure it's super popular. While the idea of Catwoman and Batman having a complex relationship is well - loved, the specific idea of Catwoman whipping Batman might be a bit more niche. However, in a community as large as the Batman fan community, there are bound to be some who enjoy exploring this more edgy and unusual concept.

One possible plot could be that Catwoman discovers she's pregnant and has to decide whether to tell Batman. She might be worried about how he'll react, considering their complex relationship. Maybe she tries to keep it a secret at first, but as the pregnancy progresses, it becomes harder to hide. Batman, on the other hand, might start to notice some changes in her behavior and become suspicious.

Here's a plot twist: Catwoman steals a powerful artifact that she believes is being misused by a powerful figure in Gotham. However, it turns out that the artifact is the key to a much greater threat that only Batman can understand. Now Catwoman has to work with Batman to put the artifact back where it belongs and stop the impending doom, all while dealing with their complex relationship.

Well, it could start with Batman finally realizing his deep love for Catwoman. Maybe they decide to have a secret wedding to avoid their enemies finding out. Their friends from the Gotham underworld and Batman's allies could be in attendance, creating a very unique mix of guests at the wedding.

A popular 'Batman and Catwoman Fanfic' is 'The Thief and the Dark Knight'. It's set in an alternate Gotham where Catwoman is on a mission to steal a precious artifact, and Batman has to stop her while also dealing with his growing feelings for her. There are also some really good ones on Archive of Our Own, like 'Gotham's Lovers' which shows their relationship from the perspective of the citizens of Gotham.

A fanfic could explore what would happen if Catwoman found out Batman's true identity before he was ready to reveal it. Maybe she uses this knowledge to try and protect him from a threat that is specifically targeting Bruce Wayne, and in the process, their relationship takes an unexpected turn.

There's a fanfic called 'Midnight Rendezvous'. In this one, the setting of Gotham at night is vividly described. The encounters between Batman and Catwoman are filled with tension and passion. The writer has a unique style of writing their dialogues, which makes it a very engaging read.

A great plot could be that there's a masked vigilante hunter in Gotham who targets both Batman and Catwoman. They have to hide from this hunter while also trying to figure out who it is. Along the way, they take refuge in an abandoned part of the city and during this time of forced proximity, they have deep conversations about their motives, their pasts, and what they really want for the future of Gotham.

One possible plot twist could be that Catwoman is forced to work undercover for one of Batman's enemies to protect Batman, but Batman doesn't know. This would create a lot of tension between them as he tries to figure out why she seems to be acting strangely.

One popular theme is their romantic relationship. Writers often explore how they fall in love despite being on different sides of the law. Another is their team - up against other villains. They both have unique skills, and a fanfic could focus on how they combine their abilities to take down a powerful foe. Also, there are stories about Catwoman's backstory and how Batman comes to understand her more deeply through that.
