No way. Harry Potter's story revolves around a boy wizard who discovers his magical heritage and battles against the dark wizard Voldemort. It's set in a world that is somewhat parallel to our own but with a hidden magical society. Peter Pan is about a boy who never grows up and his adventures in Neverland. The plots, the character arcs, and the overall concepts are so different. Just because they are both in the realm of fantasy doesn't make Harry Potter Peter Pan fanfiction.
One possible plot could be that Peter Pan takes Harry Potter and his friends to Neverland. There, they encounter the Lost Boys and Tinker Bell. Harry discovers new magic in Neverland that's different from Hogwarts magic. They could also face a common enemy, like a dark force that's trying to take over both Hogwarts and Neverland. The wizards could teach the Lost Boys some basic spells, and in return, the Lost Boys could show them how to fly better than on broomsticks.
One idea could be that Peter Pan takes Harry Potter to Neverland to escape from Voldemort. In Neverland, Harry discovers new magical abilities that are different from those in the wizarding world. He could learn to fly in a more carefree way like the Lost Boys and use his magic in new and exciting environments.
Peter Pan would likely be very curious about Harry's magic wand. He might try to play with it or see what kind of unique spells Harry can do. Harry, on the other hand, would be intrigued by Peter's ability to fly without a broomstick. They could start off with a bit of a friendly rivalry, each showing off their own magical skills.
One great 'Harry Potter' and 'Peter Pan' fanfiction is 'The Lost Boys at Hogwarts'. It combines the magic of Hogwarts with the Neverland charm. The characters from both worlds interact in really interesting ways, like how Peter Pan might react to the spells at Hogwarts. Another good one could be 'Pan in Potter's World' which has a unique take on how the two different magical realms could co - exist.
I think Harry Potter himself would be very interesting. Imagine him in Neverland, a place so different from Hogwarts. He could bring his courage and sense of justice from the wizarding world and apply it in the new setting. His magic skills would also be fascinating to see in the context of Neverland, like how he would use spells against the likes of Captain Hook or other threats there.
Well, to prove it, consider the themes. Harry Potter has themes of friendship, courage, and the fight against evil in a very specific context of a hidden magical world within the Muggle world. Peter Pan has themes of childhood, growing up (or not), and the allure of a fantastical place. The settings are also distinct. Hogwarts and its associated locations are very different from Neverland. And the character development in Harry Potter is a long - term process throughout multiple books, while in Peter Pan, the characters are more static in their nature. So, clearly, Harry Potter is not Peter Pan fanfiction.
Well, it could be really interesting. Maybe Harry would grow up with a sense of adventure and a love for the fantastical similar to what's in Peter Pan stories. He might be more carefree and less burdened by the weight of the wizarding world's problems at first.
Peter Pan might be jealous of Henry. Maybe Henry has something that Peter Pan desires, like a special magical ability or an object. So, to get it for himself, he endangers Henry.
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.
