The relationship between Catwoman and Dick Grayson can be depicted as a detective - informant relationship. Catwoman has her ears to the ground in the criminal underworld and provides Dick with valuable information. Dick has to trust her, which is difficult for him given her past. Another portrayal could be that of a cultural exchange. Catwoman comes from a more street - smart and self - serving background, while Dick has the discipline and training of the Bat - family. They teach each other about their different ways of life. It could also be shown as a relationship of convenience. They both need something from each other at a particular moment. For example, Catwoman needs protection from a certain enemy, and Dick needs her help to infiltrate a criminal organization. So they form a temporary alliance that may or may not develop into something more.
Their relationship could be portrayed as a mentor - mentee relationship. Catwoman, with her years of experience, could be teaching Batman Beyond some of the more subtle aspects of crime - fighting, like how to read a criminal's motives just by observing their body language. Another way is to show them as rivals in a different sense. Instead of just fighting over loot, they could be competing to solve a mystery first. Or, they could be portrayed as reluctant allies. They don't trust each other completely, but they know that they need to work together to stop a greater evil.
A good plot could be that Catwoman steals a valuable item that has some connection to Dick Grayson's past. Dick, as Nightwing, tracks her down. Instead of fighting, they start to talk and realize that there are bigger forces at play trying to frame Catwoman for a crime she didn't commit. They then join forces to clear her name and expose the real villains. Or, there could be a story where Catwoman and Dick Grayson meet at a masquerade ball in Gotham. They don't know each other's identities at first and end up sharing a dance and a deep conversation. Later, when they discover who they really are, they have to deal with the fact that they are on different sides of the law but still have feelings for each other. Also, a plot could be about Catwoman teaching Dick Grayson some of her stealth skills, and in return, Dick teaches her some acrobatic moves. This leads to a closer relationship between them and they end up using their combined skills to stop a major crime in Gotham.
Dick Grayson's character could become more self - reliant in this fanfiction scenario. He would have to figure things out on his own, like dealing with villains and protecting the city. This self - discovery process could lead to a more complex character. Instead of relying on Batman's resources and guidance, he might create his own methods and tools. His relationships with other characters would also be different. For example, his connection with Alfred might be less formal since there's no Batman - Robin connection. This would all contribute to a different kind of character development for Dick Grayson.
One way to develop their relationship is through a shared mission. Maybe they both want to take down a powerful and corrupt organization in Gotham. They start working together reluctantly, but as they face challenges together, they begin to trust each other. Dick could start to see the good in Red X, and Red X could start to admire Dick's skills and sense of justice. They might even exchange some of their skills and knowledge, like Dick teaching Red X some combat moves and Red X showing Dick some stealth techniques. Another aspect could be that they discover they have a common enemy from their pasts, which binds them together.
Their relationship could be portrayed as more of a partnership in the Clone Wars. Instead of just a romantic couple, they could be shown as two people with different skillsets who are equally important in achieving victory. For example, Padme could be more involved in the military strategy discussions with Anakin, using her political knowledge.
Rather than the Cheshire Cat being the mysterious figure that it usually is, it could be shown as a more vulnerable character in relation to Alice. Maybe it depends on Alice for some kind of emotional support. This would flip the typical dynamic and show a different side of the cat. For instance, when the cat is facing a threat that it can't easily disappear from, it turns to Alice for help.
Their relationship could be portrayed as a mentor - mentee one, where She - Hulk looks up to Hulk for his experience in dealing with his powers and the world of superheroes. Another way is to show them as rivals, competing to see who can save more people or defeat more villains in a given time. This would add a new dynamic to their interactions.
Ancalagon could also be shown as more intelligent. Maybe in fanfic, he's not just a brute force but a master strategist, planning his moves carefully in the stories. He could outwit other characters through his cunning.
In fanfic, their relationship can be less hostile. For example, Snape may not be as harsh with Harry in class as he was in the books. He could be more understanding of Harry's situation, especially considering Harry's role in the fight against Voldemort.
Their relationship could be portrayed as a mentor - mentee relationship in a different way. Instead of Orochimaru trying to use Naruto for his own gain, he could genuinely see Naruto's potential and guide him in the ways of some of the more esoteric jutsu. For example, Orochimaru could teach Naruto about the secrets of the snake contract without any ulterior motives. Another way is to show them as reluctant allies. Maybe there's a common enemy that is so powerful that they have no choice but to work together, and over time, they start to respect each other's abilities.
