One plot idea could be that Harry discovers Peter's secret identity as Spider - Man by accident. Maybe he sees Peter changing into his suit in a hidden alley. Then, instead of being angry or jealous, he decides to help Peter in his fight against crime. He could use his Oscorp resources to create new gadgets for Spider - Man.
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.
One great fanfiction could be where Harry discovers Peter's secret as Spider - Man early on. It might explore how their friendship changes and how Harry could potentially help Peter in his superhero duties. Maybe Harry uses his wealth and resources to create better gadgets for Peter.
One plot idea could be that Gwen discovers a new superpower that she has to learn to control, and Peter helps her through the process. This could add a new dynamic to their relationship as they both have different powers and ways of handling them.
In some fanfictions, there could be a story where Harry discovers Peter's secret identity in a unique way. Maybe he stumbles upon Peter changing into his Spiderman suit by accident. Then, their friendship takes a new turn as Harry has to decide whether to support Peter or be angry about the secrecy.
One idea could be that Harry Potter somehow gets transported to Neverland. He could teach the Lost Boys some magic, and they in turn could show him how to have fun in a more carefree way than at Hogwarts. Another idea is that Peter Pan visits Hogwarts and causes chaos with his flying and mischievous nature among the students and professors.
One idea could be that Peter Parker somehow gets transported to the wizarding world of Harry Potter. He could use his spider - sense to detect dark magic or hidden threats that the wizards might not be aware of. Another could be Harry Potter visiting New York and teaming up with Peter Parker to fight a common enemy, like a villain who has both magical and non - magical powers. And perhaps they could exchange skills, with Harry teaching Peter some basic spells and Peter showing Harry how to be more agile in combat without magic.
Well, 'The Bond Beyond Webs' is quite popular. It really focuses on the deep friendship between Harry and Peter. It shows how they support each other through tough times in school and in Peter's superhero life.
One idea could be that Spiderman 2099 has to team up with a group of rebels from a future dystopia to take down a powerful corporation that controls the city. They might face advanced technology and dangerous enforcers.
Their relationship could develop uniquely if Harry becomes a sort of mentor to Peter in the business and science side of things. Since Harry has access to Oscorp's resources, he could teach Peter about advanced technology that could be useful for his Spider - Man activities. This would create a different dynamic from the typical superhero - sidekick relationship.
Another idea is a time - travel fanfiction. Spider - Man could be sent back in time to when his Uncle Ben was still alive. He would have the chance to prevent his uncle's death, but he'd also have to deal with the consequences of changing the timeline, like how it might affect his own development as a hero.
