Another idea is a crossover with The Chronicles of Narnia. Peter could enter Narnia through some magical portal. He'd interact with the talking animals and the Pevensie children, and his skills in fighting pirates could be useful in Narnia's battles.
One idea could be that Peter Pan and his Lost Boys end up in a different Disney world, like the world of Beauty and the Beast. They might mistake the Beast for a new kind of pirate or monster at first. Another idea is that a Disney princess, say Cinderella, gets whisked away to Neverland by Peter Pan. She could teach the Lost Boys some manners while they teach her how to have more fun. Also, Tinker Bell could get jealous of a new Disney character who catches Peter Pan's attention, like Ariel from The Little Mermaid.
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.
Well, you could write a fanfiction where Peter Pan and Wendy grow up but still remember their adventures in Neverland. They could try to recreate that sense of magic in the real world, perhaps by opening a place where children can experience a bit of Neverland. Or, what if a new villain emerged in Neverland and Peter and Wendy had to team up in a different way than before to defeat them? They might have to use Wendy's more grown - up thinking and Peter's knowledge of Neverland's secrets.
Well, you could write a fanfiction where Peter Pan loses his ability to fly and Wendy has to help him find a way to regain it. It could involve them going on a journey across Neverland, facing various challenges and meeting new characters along the way. They might have to seek the help of the mermaids or the Lost Boys. This would not only test their friendship but also show their growth as characters.
Perhaps in the fanfiction, Peter Pan gets injured during one of his battles with Captain Hook. Jane, who has learned some basic first - aid skills from her own world, takes care of him. This leads to a deeper bond between them, and Peter starts to see Jane in a new light, not just as a visitor to Neverland but as a true friend and an equal.
One idea could be exploring Wendy's life back in London after her adventures in Neverland. Maybe she's having a hard time adjusting and misses Peter terribly. Another could be a story where Peter brings some of the Lost Boys to London for a visit and the chaos that ensues. A third idea might be a tale where Wendy's younger siblings grow up and start to doubt the existence of Peter Pan, but Wendy has to convince them he's real.
One plot idea could be a modern - day Peter Pan who discovers the real world has changed a great deal. He has to adapt to technology and new social norms while still maintaining his Neverland spirit. Another could be a story where Peter Pan meets a character from another fairy - tale realm and they go on an adventure together in Neverland. Maybe a girl from a strict, old - fashioned society stows away on his ship and he has to teach her how to have fun and be free.
One idea could be exploring Wendy's life after she returns from Neverland. Maybe she tries to bring some of the magic back to her own world. For example, she could start a club in her school about the stories of Neverland, but faces disbelief from others.
One idea could be that Baelfire gets lost in Neverland and Peter Pan has to decide whether to help him or use his situation to his advantage. Maybe Baelfire has a special power that Peter Pan wants for himself.
One idea could be that Peter Pan and Merlin meet in a magical realm between Neverland and Camelot. They team up to fight a common enemy, like an ancient evil sorcerer who is trying to steal the magic from both their worlds. Peter's ability to fly and his eternal youth could be combined with Merlin's powerful magic skills to create a really cool adventure.
