One idea could be that Henry discovers a hidden part of Neverland that Peter Pan had forgotten. Maybe it holds the key to a power that can change the fate of both Neverland and Storybrooke. For example, it could be a magical spring that has the power to grant immortality or the ability to rewrite memories.
One idea could be to have Peter Pan meet characters from other parts of the Once Upon a Time realm in a friendly competition. For instance, a race through the magical forests of Neverland against characters like Alice from Wonderland. This would be a fun and exciting story without any inappropriate content.
I really like 'The New Arrival in Neverland'. In this fanfiction, a new character enters Neverland and changes the dynamics between Peter Pan and the other residents. It has some great descriptions of Neverland that make you feel like you're really there. And then there's 'Peter Pan's Hidden Heart'. This one delves into the emotions that Peter Pan tries to hide, which is really interesting as in the show he often comes across as carefree.
Their relationship could develop through shared dreams. Henry starts having dreams about Peter Pan's past adventures in Neverland, and Peter can sense Henry in his dreams too. This creates a bond as they start communicating through the dream realm, sharing secrets and ideas.
Another theme is the power of friendship. Despite their differences and history of enmity, many fanfictions explore how they could become friends or at least allies. They might find common ground in their shared experiences in Neverland or their mutual love for adventure.
First, know the characters well. Peter Pan is carefree, adventurous, and a bit of a rebel. The reader character should be relatable. Then, create a vivid setting. Describe Neverland in all its glory, from the lush forests to the lairs of the pirates. Also, have a strong plot. Maybe the reader is on a quest to find a way back home or is helping Peter fight a new threat in Neverland.
Perhaps 'Once Upon a Time: The Reader in Peter Pan's World'. This title emphasizes the reader's presence in the world of Peter Pan, which can lead to various interesting storylines.
One great fanfiction is 'The Dark Side of Neverland'. It delves deep into the complex relationship between Peter Pan and Felix. It shows how Felix is extremely loyal to Pan and the lengths he would go to protect Pan's rule in Neverland. The story has a great deal of adventure and mystery, making it a thrilling read.
One great 'Peter Pan Wendy Once Upon a Time Fanfiction' is 'Wendy's New Adventure in Neverland'. It takes Wendy on a different journey in Neverland, exploring her relationships with Peter Pan and the Lost Boys in a fresh way.
