One great fanfiction could be about Catwoman's origin story within the animated series' universe. Maybe she starts as a small - time thief in Gotham's slums and gradually rises to become the iconic cat burglar we know. She could have a complex relationship with Batman that is explored more deeply, like her internal struggle between her feelings for him and her life of crime.
An interesting idea is to write a story where Catwoman discovers a secret about Batman's past that even he doesn't know. This could lead to a strange alliance between them as they both try to figure out what the discovery means. It would also add a new layer to their relationship.
One scenario in the fanfiction could be that Batman gets jealous when he sees Catwoman flirting with a rich businessman during one of her heists. He might start to question her motives and their relationship. This jealousy could cause him to act out of character, perhaps being more aggressive or possessive towards Catwoman than he normally would be. And Catwoman, being the independent character she is, would not take kindly to this sudden change in Batman's behavior, leading to a rift between them that would be interesting to explore in the story.
One idea could be a fanfiction where Poison Ivy teams up with another villain, like the Joker. They could have a really strange alliance. Maybe she uses her plant powers to help him with one of his crazy schemes, but in the end, she double - crosses him because she realizes his plans are too chaotic even for her. It would be an interesting exploration of her character and how she interacts with other villains in the Batman universe.
A way to develop their relationship in this type of fanfiction is through joint parenting. They might have different approaches to raising their kids. Batman could be very strict about discipline and training, while Catwoman might be more lenient and focus on teaching the kids about the importance of freedom. Through these differences, they learn to understand each other better and grow closer as a couple. Also, they could face external threats to their family which forces them to rely on each other more, strengthening their bond.
She might be very surprised at first. After all, Batman is not one to show his emotions so openly. But then she would likely be overjoyed. She has deep feelings for Batman too, and this proposal would be a confirmation of their complex relationship.
The Penguin often makes an appearance. He can add an extra layer of chaos and villainy to the story. His devious plans can either get in the way of Batman and Catwoman's relationship or be a catalyst for them to work together more closely.
One interesting concept could be exploring Batman's early days as a vigilante in fanfiction. Writers might show his struggles with learning to fight crime effectively while also dealing with his own inner demons.
One popular theme is redemption. Catwoman, being a thief, might be on a path to redemption with Batman's influence. Another theme is the power of love. Their relationship, whether it's a romantic one or a complex friendship, can change the course of their actions. Also, the exploration of their dual identities is quite common. How they balance their normal lives with their masked personas and how that affects their relationship with each other.
Well, in fanfiction about Batman and Catwoman from Batman Returns, one common theme is their love - hate relationship. They are both complex characters. Batman is all about justice and order, while Catwoman is more of a free spirit. In some fanfics, they end up teaming up against a bigger threat. This shows how their relationship can be more than just the cat - and - mouse chase we see in the movie. They can be allies, and that transformation is quite fascinating to read about.
