Some students would be super excited. The younger students especially would be thrilled to see cute Pokémon like Eevee around the castle. They would be eager to learn from them and make friends with the Pokémon.
Naruto would be very friendly and outgoing, quickly making friends with many Hogwarts students. He'd be eager to share his ninja stories and learn about magic from them. Sasuke would be more aloof at first. He might only interact with students who he sees as strong or useful. Gaara would be a bit of an enigma. Some students might be intimidated by him, but those who get to know him would find his quiet strength appealing.
They would probably be shocked at first. I mean, Hogwarts reading fanfiction? It's a strange concept. But then they might be really curious about what Hogwarts is reading. They could try to get their hands on the same fanfiction to see what all the fuss is about.
Some students might be in awe of him. His demigod status and the stories he could tell about fighting monsters would be really cool to them. Others might be a bit jealous, especially those who pride themselves on being pure - blood wizards and think their magic is superior. But then there would be those who would be friendly and curious, like the Weasley twins. They would probably want to team up with him to pull some epic pranks using his unique skills.
Well, in certain fanfictions, the train itself serves as a training ground. The journey on the Hogwarts Express could be filled with challenges like hidden mazes within the train cars. Students would have to use their magic skills to navigate through these mazes, which would improve their problem - solving abilities and magical proficiency. Also, the conductors or other magical beings on the train could give impromptu lessons or tests to the students.
The count of story missions in Hogwarts Legacy is hard to pin down exactly. Roughly, there are about 30, but it could be more or less depending on your gameplay style and exploration of the game world.
Percy's power over water could be used in potions class. He could manipulate water elements in the potions, perhaps making it easier to create certain water - based elixirs. Also, in Defense Against the Dark Arts, his combat skills as a demigod could be combined with defensive spells. For example, he could use his sword - fighting skills along with a Shield Charm to fend off attacks.
I think there are around 30 main story missions in Hogwarts Legacy. But it might vary depending on how you play and if you count some side quests as part of the main story.
