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.
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.
To write a good 'Batman and Catwoman Fanfic', you need to get the setting right. Gotham City should be a character in itself. Describe its dark alleys and tall buildings. Also, don't be afraid to add some new elements to their backstories. For example, what if Catwoman had a different reason for becoming a thief? And make their interactions full of tension, whether it's physical combat or a battle of wits.
A fanfic that stands out is 'United They Stand'. It imagines a scenario where the three heroes must put aside their differences and work together. The writer beautifully weaves their backstories into the plot, making it more than just an action - packed adventure. It also explores the relationships between them, like the potential romantic tension between Batman and Catwoman, and the mutual respect between Wonder Woman and Batman.
One great 'Batman Beyond Catwoman' fanfic is 'Shadows of the Night'. It really delves into the complex relationship between Batman and Catwoman in the 'Beyond' universe. The author does an amazing job of portraying Catwoman's character, giving her new layers of depth while still maintaining her alluring and mysterious nature.
One common theme is the love - hate relationship. They are often portrayed as attracted to each other but also at odds due to their different moral compasses. Another theme is the idea of redemption. Catwoman might be on a path to redemption with Batman's influence.
I'm not sure if there is such a fanfic available online. Fanfic websites have a wide variety of content, but this specific one might be hard to find or might not exist at all. It also depends on the rules of the particular fanfic platforms regarding this kind of content.
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.
Character development is key. In a great fanfic, we might see Catwoman evolving in the new world of Batman Beyond. Maybe she's facing new challenges or has new goals. Also, a good plot that ties in elements from the 'Beyond' universe, like the new technology or different social climate in Gotham, makes for an engaging fanfic. The relationship between the two characters should be complex and not just a simple hero - villain dynamic. It could be a love - hate relationship, or they could be reluctant allies at times.
