Well, he might make new friends. In a different school, there could be new magical traditions and spells for him to learn. He'd also face different challenges compared to Hogwarts.
If Harry goes to another school in fanfiction, his character could develop in various ways. He might become more adaptable as he has to get used to a new environment. His views on magic could expand as he's exposed to different teachings. Also, his leadership skills could be tested in a new setting where he doesn't have the same status as at Hogwarts. He may have to prove himself all over again, which could make him more determined and self - reliant.
He could also meet some sort of dark wizard or villain that is even more powerful than Voldemort in this new world. This would pose a great threat to Harry and force him to use all of his skills and knowledge, both from his own world and what he's learned in the new one, to defeat the enemy.
Well, he could face a whole new set of challenges. Maybe the magic there works differently. For example, spells he uses on Earth might not have the same effect, or he could encounter a powerful dark force that he has to figure out how to defeat without the help of his usual Hogwarts friends and professors. He'd have to rely on his own wits and the skills he's learned over the years to survive and overcome difficulties.
Maybe he'll have to learn a whole new type of magic. In the other world, the rules of magic could be completely different. Instead of using wands, they might use their minds directly to cast spells. So Harry would have to adapt quickly to survive and figure out how to use this new magic system.
He might struggle to adapt at first. In a muggle school, there are no magic classes or flying broomsticks. Harry would have to deal with normal academic subjects like maths and history. He'd also have to hide his magical abilities, which could be really hard when he's used to using magic for so many things in Hogwarts.
He might make a whole new set of friends. Different schools in the Harry Potter universe have their own unique cultures and student bodies. For example, if he went to Durmstrang, he'd be exposed to a more competitive and dark - arts - leaning environment. This could change his perspective on magic and his place in the wizarding world.
Well, he might face a whole new set of magical rules and traditions. Canadian magic could be more nature - based perhaps, with a focus on the vast wilderness there. He could make friends with local Canadian wizards and witches who have different accents and ways of doing magic compared to his British friends.
Well, it might be about Harry facing a whole new set of challenges in a so - called 'killer school'. Maybe there are extremely difficult and dangerous courses. For example, he could be learning spells that are not just for defense but for actual combat in a life - or - death situation. And he may encounter new enemies who are far more brutal than the Death Eaters.
Well, in such a fanfiction, perhaps Harry goes to school in Egypt to escape the danger at Hogwarts. There, he has to adapt to a completely different educational system. He could make new friends who have different cultural backgrounds and magical heritages. The school in Egypt might focus more on ancient magic, and Harry would have to work hard to catch up as he's used to the European style of magic education.
