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.
His students could also include some new students from families that have recently joined the wizarding world. Harry, who has always been inclusive, would be a great teacher for these students who are still adjusting to the magical world. He would be able to guide them through the new and often overwhelming experiences at Hogwarts, just as he was once guided by his own teachers.
Some of the more progressive magical families like the Weasleys might side with Harry. They've always been on the side of good and if Harry shows that his rule would bring positive changes to the wizarding world, they'd be his allies.
The students could range from first - years who are just starting to learn about magic to seventh - years who are about to graduate. Harry would have to adapt his teaching methods to suit the different levels of knowledge and skills among the students. He might also have some students who are particularly interested in his adventures and would be eager to learn more about the Dark Arts from him directly.
Harry's character would likely become more hardened. In Mandalore, he'd face different challenges than in the wizarding world. He'd have to be more physically tough, which would make him more confident in his own abilities. His sense of justice would also expand as he learns about the Mandalorian code. He might become more of a lone wolf, relying on his own skills rather than always having his friends by his side as he did in Hogwarts.
Perhaps Harry Potter becomes a teacher of Quidditch. He was an excellent Quidditch player himself. He would train the students in new strategies and techniques. He could also share his experiences of playing in important matches. He might organize special Quidditch tournaments within the school that have different rules and challenges compared to the regular ones, making the sport more interesting for the students.
Another possibility is that he becomes a fox. Foxes are clever and sly, which are qualities that Harry has developed over the years. As a fox, he could use his wits to outsmart his opponents. He could also easily blend into the forest environment, which would be handy for hiding or sneaking around.
Perhaps some of the magical creatures that Harry has befriended over the years, like the centaurs or the house - elves, could become his allies. They could offer their unique skills and knowledge to help Harry in his new role, and Harry, in turn, could work towards better rights and treatment for them in the wizarding world.
It could be Spider - Man. Harry Potter might relate to Peter Parker's journey of having great power and great responsibility. Just as Harry has to deal with his own powers as a wizard and the burden of saving the wizarding world, Peter has to balance his normal life with his superhero duties.
Hermione could be a main character. As a very intelligent witch, she might assist Harry in his teaching, like helping him prepare complex lessons or providing additional knowledge to the students. For example, when Harry is teaching about ancient spells, Hermione could offer insights from the books she has read.
He would probably be a very inspiring teacher. He has so much real - life experience with magic, from fighting dark wizards to solving mysteries. He could teach Defense Against the Dark Arts in a way that no one else could, sharing his own combat strategies and knowledge of dark creatures. His students would surely be in awe of him and eager to learn from his adventures.
Another potential rival could be a group of dark wizards who use street racing as a cover for their illegal activities. They see Harry as an obstacle to their operations and try to eliminate him from the racing scene. Harry has to not only compete with them on the race track but also fight against their dark magic in order to protect himself and the other racers.
