Their relationship can be developed through shared experiences. For example, when they face a tough villain together, they start to understand each other's fighting styles and strategies better. This mutual respect can lead to a deeper bond. Also, having them save each other's lives can strengthen their connection. Like when Miles Morales is in a dangerous situation and Spider Gwen swoops in to rescue him, it shows how much they care about each other's well - being.
One idea could be that Spider Gwen and Miles Morales have to team up to stop a new villain who has the ability to manipulate time. This would put their relationship to the test as they struggle to work together while also dealing with the chaos of the altered timelines. Another plot could involve them traveling to an alternate dimension where their roles are reversed, and they have to learn to adapt to each other's usual situations. A third idea is that they discover a long - lost relative who has superpowers and they must decide whether to trust this new person or suspect them of having ulterior motives.
One idea could be that Miles and Gwen team up to stop a new villain who can manipulate time. They have to race against the clock to figure out the villain's weakness before the city is frozen in a time loop. Another could be that they discover a parallel dimension where they are the only superheroes left and have to find a way to restore their respective universes.
In my opinion, Kingpin would be a crucial character to include. He could be the mastermind behind a new threat that Miles and Gwen have to face. His power and influence in the criminal underworld would make for a great source of conflict. Then there's also Silk. She has her own set of powers and a connection to the Spider - Verse. Her presence could add more depth to the relationships between the characters and bring in some new plot elements related to the Spider - powers and their origins.
There's a fanfiction called 'The Web of Bonds' which is quite interesting. It takes a more emotional approach to their relationship. It shows how Miles and Gwen support each other through tough times and how their bond grows stronger as they face different challenges in the world of superheroes.
One common theme is the exploration of their relationship in different universes. Since they are from the Spider - Verse, fanfics often play with the idea of how their relationship could develop in various alternate realities.
In Gwen Stacy and Miles Morales fanfic, the characterizations are really interesting. The writers can take the base personalities of these two characters from the comics or movies and expand on them. They might give Gwen more of a rebellious streak when she's with Miles or show Miles as being more vulnerable around Gwen.
One great fanfiction is 'Parallel Hearts' where Miles and Gwen team up to face a new villain in an alternate dimension. It has great character development and action scenes.
The plot is also crucial. It could be something that involves them working together against a new villain. Maybe a villain from another dimension who is trying to disrupt the balance in their world. A plot that keeps the readers on their toes and makes them eager to find out what happens next is always great in fanfiction.
Fanfiction.net is also a classic option. It has been around for a long time and has a huge database of fan - created stories. Check their Marvel or Spider - Man sections and specifically look for stories that involve Spider - Gwen and Miles Morales.
