Perhaps a new student named Tiger Lily. She comes to the high school and has her own set of rules and ideas. She wants to take over Peter's group of friends and tries to drive a wedge between Peter and Wendy. She's very competitive and sees Wendy as an obstacle to getting closer to Peter.
A plot could be that Wendy is a new girl in high school who is lonely. Peter Pan, who has always been in the school but never really fit in, befriends her. They start a club together that is like a secret Neverland in the school. However, the school's strict principal, Captain Hook in disguise, tries to shut it down. Peter and Wendy must fight to keep their club and their friendship alive, using their creativity and Peter's unique abilities.
It could also be a new character, perhaps a dark sorcerer who is jealous of the magic in Neverland. This sorcerer might target Emma because she has an unknown power within her that could disrupt his own plans for the magical world. He would try to separate her from Peter Pan and use her power for his own evil deeds.
Captain Hook would be an obvious choice. His hatred for Peter Pan could extend to Moira when she becomes Peter's friend. He might see her as another obstacle in his quest to get revenge on Peter.
Perhaps an older, forgotten enemy of the Lost Boys could resurface. Maybe someone from their past in Neverland who they thought was defeated but has now returned with a vengeance. This could be a character who was once a Lost Boy himself but turned bad due to some dark influence in Neverland.
It could be a new character. Maybe a dark sorcerer who has come to Neverland while Peter was growing up. This sorcerer wants to take over Neverland and sees Peter, with his new adult understanding and power, as the only obstacle. The sorcerer could start to corrupt the island, turning the mermaids and Lost Boys against Peter, making him fight not only for his place in Neverland but also for the very soul of the island.
It could be a group of outcast Lost Boys who have turned bad. They might be jealous of Wendy's special place in Peter's heart and in the group. So they kidnap her in an attempt to show Peter that they are in control now and can disrupt the harmony of the group.
The 'Peter Pan and Wendy 2003 Fanfiction' often plays with the themes of the original story. It may focus more on the theme of growing up, but in a different light. Instead of Wendy simply leaving Neverland to grow up, it could show her internal struggle between the freedom of Neverland and the responsibilities of the real world. The fanfiction might also introduce new magical elements that are related to the characters' personalities, such as Peter's ability to control a new type of magic that was not in the original story.
One popular trope is the 'What - If' scenario. For example, what if Wendy had decided to stay in Neverland permanently? Fanfiction writers often explore this idea, imagining how her life would be different and how it would affect the other characters. Another common trope is the 'Power - Up' where a character, like Wendy, might gain new powers or abilities during her time in Neverland. This can lead to new and exciting adventures.
In this fanfiction scenario, their relationship would transform in many ways. Before the baby, they were like two kids having fun in Neverland. But now, they are parents. Wendy would be the one to teach Peter about the importance of routine and stability for the baby, like proper sleeping and eating times. Peter, on the other hand, would introduce the baby to the wonders of Neverland. Their relationship would be a blend of their old carefree selves and their new parental roles. There might be some arguments as they adjust to their new life, but also many tender moments as they watch their baby grow and discover the world around it.
Peter Pan is definitely a popular character to focus on. His charm, his ability to fly, and his eternal youth make him an interesting subject. Wendy is also a great choice as she brings a sense of normalcy from the real world into the magical world of Neverland. And of course, Captain Hook with his villainous ways and his vendetta against Peter.
