One common theme is redemption. Peter B. Parker often has to face his past mistakes and try to make up for them. For example, in many fanfics, he might have failed in a relationship in the past and is now trying to be a better person for it.
Well, it could be due to a number of reasons. Maybe he sacrifices himself to save the city from a powerful villain. In some fanfictions, he might die in a fight against an overwhelming enemy that he just couldn't defeat on his own.
One popular Peter B Parker fanfiction might be those that explore his life in an alternate universe. For example, stories where he has different relationships with other Spider - People. Another could be ones that focus on his growth and development as a hero outside of the main storylines. There are also fanfictions that might center around his family life, like how he copes with being a father in a new and different way.
Another common theme is heroism. Since Peter B. Parker is a superhero, the fanfiction may show how MJ supports him in his heroic deeds, or how his superhero life affects their relationship. For example, he might have to choose between saving the city and being there for MJ at an important moment.
One idea could be that Peter Parker and Captain Marvel are teamed up to face a powerful cosmic threat that's approaching Earth. They initially clash due to their different approaches - Peter is more street - level and cautious, while Captain Marvel is bold and used to dealing with large - scale threats in space. But as they get to know each other better, they start to combine their powers effectively, with Peter using his spider - sense to anticipate the enemy's moves and Captain Marvel delivering powerful blows.
There could be many interesting plotlines in such a fanfiction. Maybe it could start with a strange accident that leads to Ms Marvel becoming pregnant with Peter Parker's child. For example, some sort of magical or scientific experiment gone wrong. Their relationship would then be tested as they deal with the challenges of an unexpected pregnancy. They would have to face the reactions of their friends and families, like Peter's Aunt May and Ms Marvel's own family. Also, they would need to figure out how to balance their superhero duties with the impending parenthood.
One great 'Marvel Peter Parker Fanfiction' is 'Spider - Man: Homecoming'. It really delves into Peter's life as a high - school student while also being Spider - Man. It shows his struggles with balancing school, friends, and his superhero duties in a very relatable way.
Mary Marvel, with her superhuman strength and flight abilities, could come to Peter Parker's aid when he's facing a villain that is too powerful for him alone. Peter, in turn, could use his intelligence and web - slinging skills to help Mary in a more urban or tricky situation. For example, if they were in a city filled with traps set by a villain, Peter could guide Mary through them using his knowledge of the terrain.
