Well, they could start off not getting along so well. Peter might be a bit overprotective or skeptical of Miles at first. But as the story unfolds, they realize they have a lot in common. They could end up sharing their stories about becoming Spider - Man and how they deal with the pressures of being a superhero. They might also explore each other's neighborhoods and learn from the different cultures there.
Perhaps a new villain created specifically for the fanfiction. A mad scientist who has been studying the powers of Spider - Man and has developed a way to nullify their powers temporarily. This would force Peter and Miles to rely on their wits and non - power - related skills to defeat him.
I really like 'Peter and Miles: The Mentor - Protégé Relationship'. This fanfic beautifully portrays how Peter takes Miles under his wing and guides him in the world of being a superhero. There's also 'Miles Morales: Learning from Peter Parker'. In this story, Miles has to adapt to Peter's more experienced style of heroics. 'Spider - Man Duo: Peter and Miles' is a great read too. It shows their friendship evolving as they fight crime side by side.
A major theme is the passing of the torch. Peter, being the more experienced Spider - Man, imparts his knowledge to Miles. And then there's the theme of identity. Both characters struggle with their dual identities as normal people and superheroes, and in fanfiction, this is often explored in the context of their relationship with each other.
There's a fanfiction called 'The Two Spiders'. In this, Peter and Miles have to deal with a reality - bending threat. It delves deep into their relationship, with Peter acting as a mentor to Miles, and Miles bringing in his fresh perspective. It's full of action and heart - warming moments.
Another theme is the exploration of their different backgrounds. Peter B is from a different era and has his own set of experiences, while Miles is a modern - day hero. Fanfictions often play with how these differences interact. For example, in some stories, Miles teaches Peter about new technology while Peter teaches Miles about the old - school ways of being a hero. It makes for an interesting dynamic.
The relationship in this fanfiction is a source of great character development. Peter B Parker might be a bit jaded at times, but Miles Morales' enthusiasm can reignite his passion. For example, Miles' unique powers and his way of using them can inspire Peter to think differently about his own abilities. They also might have some comical moments together, like when Miles tries to teach Peter some new - age lingo or technology that Peter is not familiar with.
In some fanfictions, the cultural differences between Peter and Miles are explored. For example, Miles' Afro - Latino heritage adds a new dimension to their relationship. Also, the different generations of being a Spider - Man come into play. Peter has been around longer and has a more traditional approach, while Miles brings in fresh, modern ideas.
One popular plot is the 'passing - the - torch' concept. Peter B Parker, seeing the potential in Miles Morales, decides to train him to be a better Spider - Man. This involves teaching Miles about his powers, combat skills, and the great responsibility that comes with being a superhero.
