There's also 'Harry and Peter: A Different Path'. This one explores what would happen if Harry took a more active role in Peter's superhero world from the start. It delves into their relationship dynamics and how it affects the people around them, like Aunt May and MJ. It's full of action - packed scenes and emotional moments between the two characters.
Well, a really cool 'Peter Parker is Spider - Man' fanfiction could involve him traveling to an alternate dimension where he's not the only Spider - Man. He could learn new skills and ways of being a hero from the other versions of himself. Some fanfictions might also explore what would happen if Peter lost his powers temporarily and had to rely solely on his wits and martial arts training (which he surely has). It would be a great character - building story for him.
One interesting fanfiction could be about Peter and MJ's daily life together in New York, dealing with normal problems while also having to keep Peter's identity a secret. It might show MJ being supportive when Peter has a tough time as Spider - Man.
A really cool fanfiction idea could be Peter in a steampunk - style world. He has to use his spider - skills in a world filled with gears, steam - powered machines and dirigibles. His web - slinging would be different, perhaps having to deal with the mechanics of the world, like using his webs to repair or disable machines.
One great fanfiction could be 'Peter and Mary Jane's New Adventure'. It might focus on their relationship in a new setting, like a different city where they have to face new villains together while also dealing with their personal issues.
One interesting storyline could be Peter and Harry teaming up against a new villain in the city. They combine their skills and resources to take on this threat that neither could handle alone.
A plot could involve Harry getting powers as well, not just from the Goblin formula but in a different way related to some Oscorp experiment. He and Peter then have to figure out how to control their powers together and face a new supervillain created by Oscorp's misdeeds. It would add a new dynamic to their relationship as they both struggle with their newfound abilities.
