Maybe some young mutants that Harry discovers during his travels in the Muggle world. He could sense their powers and offer them a place at his new school.
His own children could be among the first students. They would bring their own experiences of growing up with Harry Potter as a father, and also their unique magical abilities. And Neville Longbottom's children might also be there. Neville has always been a great friend of Harry's and his kids would inherit Neville's strong sense of justice and love for plants, which could add a different dimension to the student body.
In the fanfiction, the first students could be a mix of young wizards and witches who have shown exceptional magical abilities but didn't fit into the traditional Italian magical schools. There might be a young wizard who has an affinity for ancient Roman magic but was not encouraged in his previous school. And a witch with a talent for transfiguration but was bullied in her old place. Harry Potter's new school in Italy could be their new home, where they can explore their magic freely.
One possibility is that Harry Potter, using his knowledge of magic and experiences, decides to create a school for mutants. He could use spells to protect the school from the outside world and those who might fear the mutants. He might also teach the mutants how to control their powers, just as he learned to control his magic at Hogwarts.
Harry Potter himself could be a mutant in the fanfic. He might discover he has mutant powers on top of his wizarding abilities, like the power to heal without using magic spells. This would make his character even more complex and powerful.
Well, it depends on the specific fanfiction. There are countless fanfictions out there, and each writer can have their own take on it. Some may choose to make Harry Potter a powerful mutant, perhaps by giving him unique genetic mutations that enhance his wizarding abilities or give him entirely new powers. However, not all fanfictions will follow this concept. Some might stick closer to the original idea of Harry as a wizard without any mutant aspects.
Hermione is often a popular character in such fanfictions. Her intelligence can be combined with mutant - like powers, say super - intelligence where she can process information at an even faster rate. She could use this to solve complex magical and mutant - related problems.
Well, it could be a wild mix of magic and mutation. Maybe Harry Potter uses his magic to accidentally create a mutant in the world of 'sch' (whatever that is in the fanfiction context). It could lead to a whole new set of adventures as he tries to deal with the consequences of this creation, like trying to find a way to control or help the mutant.
He could meet a brilliant but eccentric teacher. This teacher might be an expert in a very rare branch of magic that Harry has never heard of before. The teacher could take Harry under their wing and teach him things that Dumbledore or the other Hogwarts teachers never did.
It could be a mix of students from different houses. In Hogwarts, students from all four houses come together for classes. Harry, having experienced the unity and rivalry among the houses, would be able to handle the diverse group of students well. He might encourage more inter - house cooperation in his classes, breaking down some of the traditional house rivalries.
Harry Potter himself is often a popular character in such fanfiction. Writers like to explore how he would interact with mutant wizards, maybe he would befriend them and help them fight against discrimination. Hermione is also popular as she could be intrigued by the new forms of magic mutant wizards possess and study them.
