Well, one aspect could be the idea of eternal youth. It's not as idyllic as it seems. Peter Pan never grows up, which can be seen as a kind of horror in a way. He's stuck in a limbo of childhood, unable to experience the full range of human emotions and development. Also, the Lost Boys' situation is a bit eerie. They are in Neverland, a place that seems like a dream but also has its dark sides, like the constant battles with pirates.
Peter Pan's shadow became a horror in Neverland. It no longer mimicked Peter's jovial movements. Instead, it grew and grew until it was a towering figure of blackness. It lurked in the shadows of the trees, waiting for unsuspecting fairies to pass by. When it caught them, it wrapped around them, draining their magic and leaving them as lifeless husks. The once - happy place was now filled with fear because of this terrifying shadow.
Well, Peter Pan's shadow can be a horror because it has the ability to be everywhere yet unseen. It could be lurking just around the corner, waiting to pounce. And since it's a shadow, it can blend into the darkness easily. It might also have the power to possess things or people, changing them into something unrecognizable and full of malice, which makes it a truly horrifying element.
Peter Pan is in love with Wendy. Wendy's arrival in Neverland changes things for Peter. She brings a sense of warmth and home - like feeling. Peter is drawn to her because she has qualities that are lacking in Neverland. She can cook, tell stories, and provide a nurturing presence. Peter's love for Wendy is shown through his eagerness to have her stay in Neverland and be part of his world, although he doesn't fully understand the nature of adult - like love.
Emphasize the passage of time in a twisted way. Since Peter Pan doesn't age, show how the outside world moves on without him in a really sad and spooky way. Maybe the people he knew in the real world grow old and die while he remains the same. Also, make Captain Hook's backstory even more tragic and his actions more brutal in his pursuit of Peter Pan.
In many Disney Peter Pan fanfictions, Peter Pan does get hurt. Writers may do this to add depth to his character. When he gets hurt, it can lead to different reactions from the other characters in the story, like Wendy taking care of him. It also allows for a different kind of growth in the story. For example, he might become more cautious or learn a valuable lesson about his overconfidence. And it can also create new storylines where the characters have to find a way to heal him, which can be very interesting to read.
Captain Hook would initially feel victorious. But then he might realize that Peter was an important part of Neverland's balance. Without Peter, the eternal battle that gave his life purpose is gone. He could start to feel lost and even a bit regretful for all the times he tried to kill Peter.
Peter Pan doesn't really have a traditional romantic love story in the classic sense. He has a special relationship with Wendy. Wendy is like a mother figure and a friend to Peter. He enjoys her company and they go on adventures together in Neverland. But it's not a typical grown - up love. It's more of a childish, innocent bond.
Peter Pan could be developed by showing his struggle with the new emotions and responsibilities that come with adulthood. For example, he might feel guilt for leaving Neverland in the past. He could also be developed through his relationships, like having a more complex friendship with the Lost Boys as an adult.
Henry Mills is also commonly paired with Peter Pan in fanfiction. Henry's connection to the world of fairy tales and his inquisitive nature might draw him to Peter Pan. They could form a mentor - mentee relationship, with Peter Pan teaching Henry things about the magic he doesn't know yet, or they could be on opposite sides in a conflict within Storybrooke.
