Perhaps it focuses on her relationship with her father, Captain Hook. She might struggle between loving him and seeing his wrongdoings. For example, she could try to convince him to stop his revenge against Peter Pan. There could also be a sub - plot about her making friends with the Lost Boys, which would create a lot of tension considering her father's enmity with them.
It could be about the daughter's adventures in Neverland. Maybe she tries to change the way pirates are seen there.
Obviously, Captain Hook's daughter would be a main character. And Captain Hook himself would play a significant role as well.
Perhaps Peater Pan's Daughter is on a mission to retrieve a magical item that has been stolen by the pirates led by Harry Hook. She infiltrates their ship and tries to steal it back, but Harry Hook catches her. Instead of punishing her immediately, he becomes intrigued by her. As they interact more, they realize they have more in common than they thought, and a relationship begins to form between them. This could involve a lot of adventure, like exploring hidden caves in Neverland and having to work together to defeat magical guardians of the caves.
She is often rebellious. Since her father is a villain, she might want to oppose his ways and create her own path.
Well, one possible plot could be that Harry discovers his true heritage as Captain Hook's son. This might lead to him having some unexpected pirate - like abilities. He could have a natural skill with a sword, for example. And perhaps he would be drawn to the sea more than he is to Hogwarts. He might struggle to fit into both the wizarding world and the pirate world he's suddenly connected to.
A third theme is the exploration of their backstories. Fanfic authors often like to fill in the gaps in their original stories. So we might see stories about how Captain Hook lost his hand in a different way related to Gothel, or how Gothel came to be so obsessed with youth in relation to Hook's own desires for immortality.
One interesting plot could be the daughter's struggle to break free from her father's villainous shadow. Maybe she tries to make amends for his wrongdoings in Neverland.
Captain Hook's origin story varies depending on the version. In some, he was a pirate who had a run-in with Peter Pan and lost his hand to a crocodile.
Adventure is also a big theme. They are often on some sort of quest or journey together. For example, they might be searching for a magical artifact while also dealing with their feelings for each other. And there's also the theme of trust. Since they come from different sides, learning to trust each other is a crucial part of many fanfics.
One common theme is redemption. Captain Hook often has a past full of misdeeds, and in these fanfics, his relationship with Emma Swan can be a part of his journey towards redemption. For example, in many stories, he tries to change for her.
Captain Hook was sailing on the sea one day. He saw an island in the distance. As he got closer, he noticed strange lights. His crew was a bit scared, but Hook was curious. When they landed, they found a magical forest. There were fairies flying around. Hook was about to catch one when he heard a strange noise. It was a big, friendly bear. The bear told Hook that this was a peaceful place. Hook decided to stay for a while. At night, he lay under the stars, listening to the bear's stories, and soon fell asleep.
