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 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.
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 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.
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 interesting concept could be the interaction between magic in the Harry Potter world and the Neverland magic in Peter Pan's realm. For example, how would a Hogwarts student react to flying without a broom in Neverland? Another concept might be the characters' crossovers. Imagine Harry Potter and his friends meeting Peter Pan and the Lost Boys. They could learn different survival skills from each other, with Harry's group teaching about potions and spells, and Peter Pan's group showing how to live freely in the wilds of Neverland.
There's a fanfic that combines the Forbidden Forest in 'Harry Potter' with the jungles of Neverland. In this story, characters from both universes explore this new and dangerous area. It's creative because it makes you wonder how a centaur would react to a mermaid from Neverland. Also, the fanfiction 'Magic Merge: Potter and Pan' where the two different types of magic start to blend and create new spells is really imaginative.
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.
