Percy would likely be very critical of their lifestyle. He comes from a world where family is important and they support each other in the face of danger. The Dursleys, on the other hand, seem to shun anything out of the ordinary and are unkind to Harry. Percy might try to show them a different way of living, with more love and acceptance, though they probably wouldn't listen.
Well, Percy would probably be really confused by the Dursleys' strange behavior. He's used to the world of demigods, and the Dursleys are so ordinary yet so mean in their own way. He might use his powers on accident and freak them out, like making water from the tap go wild when Dudley is being a bully.
In this fanfiction concept, imagine Savitar being from a different dimension and accidentally stumbling into the Percy Jackson universe. He doesn't understand the rules at first. The demigods are initially scared of him because of his speed and strange powers. But Annabeth, being the smart one, figures out a way to communicate with him. Through their interactions, Savitar starts to question his own motives and actions, leading to a character arc where he may even end up helping the demigods against a greater threat.
Well, Daphne in the 'Daphne meets the Dursleys fanfiction' would probably interact with the Dursleys in a very cautious way at the start. She would be observing their behavior towards Harry closely. Once she realizes the extent of their nastiness, she could try different approaches. She might try to reason with them, explaining how wrong it is to treat a child like that. When that doesn't work, she could use her magical abilities to disrupt their daily routine in a harmless but annoying way, like making the TV constantly change channels or the kettle never boil. This would be her way of getting back at them for their treatment of Harry and also a way to show them that there are forces they don't understand.
A typical scenario could be Percy seeking Poseidon's help. For example, if Percy is in a tough battle against a powerful enemy, he turns to his father. Another is Poseidon coming to Percy to give him a task, like protecting a certain sacred place in the ocean.
Well, they might start comparing their heroic deeds. Percy could talk about his adventures with the Greek gods and monsters in the modern world, like fighting the Minotaur in a New York museum. Theseus would probably share his own tales of slaying the Minotaur in the labyrinth long ago. They could also end up teaming up to face a new threat that emerges in the fanfiction world, perhaps a powerful new monster created by an angry god.
Well, it could be really cool. Percy's water powers and his demigod skills might clash or collaborate with the Avengers' superpowers. For example, he could use his water - controlling abilities to help Thor with his lightning strikes, making them even more powerful. Maybe he and Captain America would bond over their sense of duty and leadership. It would be an epic crossover full of action and adventure.
The story in the fanfiction could start with Percy getting lost and somehow ending up in the world of the Unwanteds. At first, he might be confused and on guard. But as he starts to understand the Unwanteds and their situation, he decides to help. He could use his ability to communicate with sea creatures to get information or assistance. The Unwanteds could be amazed by Percy's powers and his connection to the gods. They might ask him to train them in combat or survival skills. And in return, the Unwanteds could share their unique magical arts with Percy, which could give him an edge in future battles in his own world.
