They could have all sorts of adventures. Maybe they'd get sorted into different houses and have to deal with the rivalries that come with that. Percy might use his water - controlling abilities in the Hogwarts' lake, and Thalia could use her lightning powers during a stormy Quidditch match. Nico could explore the Hogwarts' underground secrets, using his underworld - related skills to uncover hidden chambers.
Well, they could find themselves in the middle of a mystery involving a dark wizard at Hogwarts. Percy's leadership skills would come in handy as they try to figure out what's going on. Thalia would be great at protecting the group with her physical strength and lightning. Nico could communicate with any ghosts in the castle to gather information. They'd also have to adapt to the different magical subjects like Transfiguration and Potions.
In this kind of fanfiction, they might face challenges adjusting to the new magical environment. Percy could be confused by the different types of magic in Hogwarts compared to his own demigod powers. Nico might struggle with the more structured and rule - bound nature of Hogwarts. Thalia could find it interesting but also be a bit rebellious against some of the Hogwarts traditions.
Percy would probably be very friendly and try to form study groups with the Hogwarts students. He's used to being a leader, so he might even start some new clubs. Thalia would be a bit more standoffish at first, but once she gets to know some students, she'd be very protective of them. Nico would be the mysterious one. The Hogwarts students might be a bit scared of him at first, but once they see his softer side, they'd become friends.
Perhaps a new character introduced in the fanfiction. A seemingly friendly newcomer who infiltrates their group, gains their trust, and then betrays them at a crucial moment. This character could be working for an enemy force, either from the Titans or some other ancient power that wants to see the downfall of Percy, Thalia and Nico.
Well, it would be quite chaotic. Percy could teach a water - based magic class, perhaps something related to controlling water elements. Thalia, with her electric powers, might teach a class on lightning - like spells. Nico, being the son of Hades, could teach about the darker aspects of magic, like dealing with the undead. But they would also have to adapt to Hogwarts' rules and traditions which would be a hilarious and challenging process.
Well, perhaps Percy and Nico could be transferred to Hogwarts through some sort of magical accident. Maybe they'd have to deal with the different magical system there compared to their own world. They could make new friends among the Hogwarts students and get involved in the typical Hogwarts adventures like the Triwizard Tournament or dealing with a new dark threat.
They might have all kinds of adventures. Ichigo could use his Soul Reaper powers in the magical world of Hogwarts. Maybe he'd face off against dark wizards with his zanpakuto. Dark Ichigo, being more chaotic, might get into trouble with the Hogwarts rules and end up in a duel with some of the more hot - headed students.
In a fanfiction where they go to high school, Percy would likely be popular for his heroic deeds and good looks. He might join the swim team and break all the records. Thalia could be the cool girl who rides a motorcycle to school and gets into trouble for parking it in the wrong place. Nico would be the mysterious new kid. There could be a plot where they have to team up to stop a monster that is lurking in the school basement.
They could be like siblings. Percy and Thalia might act as the older siblings, protecting and guiding Nico. Percy, with his leadership skills, and Thalia, with her combat abilities, would be great at looking out for the younger Nico. They could also be like cousins, with a close - knit bond but still having their own individual family heritages that sometimes create interesting dynamics.
Percy and Nico might grow closer as they face new challenges together in Hogwarts. Thalia could initially be a bit of an outsider to their relationship but then gradually become more involved. Percy could act as a mediator between Nico and Thalia at times.
The students would be in awe. Percy's heroic deeds would make him a star among the students. They would be eager to learn from him. Thalia's cool and powerful aura would intimidate some but also draw others. Nico's dark and mysterious nature would fascinate the more adventurous students. Some might be scared at first, but overall, they would be excited to have such different and powerful teachers.
