To write these characters in a modern high school setting, first, study the original characters well. Celaena is fearless in the original, so in high school, she could be fearless in standing up to bullies. She might be the girl who wears black all the time and has a mysterious air about her. Chaol could be the military - like student, maybe part of the ROTC program at school. He's always serious and focused. Dorian could be the guy who throws the best parties but also secretly studies a lot. You can also add new characters like the mean girl who is jealous of Celaena's popularity or the nerdy kid who becomes Celaena's unlikely friend and helps her with her studies.
In a high - school setting, Sakura would probably be very popular due to her kind heart and strong will. She'd be involved in various extracurricular activities. Shikamaru would be the type to avoid the spotlight, but his intelligence would not go unnoticed. As they interact more, Sakura could help Shikamaru come out of his shell a bit. He could, in turn, teach her to be more patient and think things through more carefully, which would further develop their characters.
One idea could be Celaena as the new student at high school who is secretly a badass assassin in training. She gets involved in a mystery where students are disappearing and she uses her skills to solve it. Another could be a high school version of the Throne of Glass tournament, where students compete in various challenges like in the books.
In high school, Luffy would be the outgoing and fearless type. He'd be the one to always speak his mind, no matter what. He might not be the best at academics, but he'd be super popular because of his friendly and adventurous spirit. He'd be the first to volunteer for any exciting activities or challenges. Nami, on the other hand, would be more studious. She'd be focused on getting good grades and would be quite popular among the teachers. However, she could also be a bit bossy at times, especially when it comes to group projects or getting things done in an organized way.
Deidara's impulsive nature might lead him to make decisions quickly without much thought, which would worry Sakura. But his passion for art could be inspiring to her. Sakura's determination and hard - working attitude could seem boring to Deidara at first, but as they interact more, he would realize how valuable those traits are. In group projects, for example, Sakura's organization skills and Deidara's out - of - the - box ideas could make their team stand out, showing how their personalities can both clash and work well together in a high school environment.
In high school, their relationship could start with small things like sharing Pokémon treats during lunch break. As time passes, they might study together for Pokémon biology classes. Ash could help Serena train her Pokémon in the schoolyard, which would bring them closer.
In the high school, there could be a Pokémon daycare center where students can leave their Pokémon during classes. Ash and Dawn could volunteer at this daycare, taking care of the Pokémon and teaching them new tricks. This would also be a place where Pokémon interact with each other, leading to some fun and chaotic situations.
In a high school setting, Inuyasha's brash nature might get him into trouble. Kagome, being kind - hearted, would probably help him out. Their relationship could start as a friendship where Kagome tutors Inuyasha. As time goes on, they might realize their deeper feelings during a school event like a dance or a sports competition.
Develop Grimmjow's character by showing his loyalty to his small group of friends in high school. He may seem rough on the outside, but he would do anything for his friends. In contrast, Ichigo is more of a loner type who is focused on his studies and family. When they interact, Grimmjow's extroverted nature starts to draw Ichigo out of his shell. You can also show Grimmjow's pride in his appearance, always wearing the coolest clothes, while Ichigo is more simple. This contrast can lead to some interesting exchanges between them.
Sakura might become more confident in her own abilities. In high school, she's exposed to different ideas and people like Deidara. His wild and free - spirited approach to art could make her less afraid to take risks in her own work. For Deidara, being around Sakura could make him more empathetic. He'd have to learn to work with someone who has a different mindset, which could make him more understanding of others in general.
To write a character for an Alex Rider high school fanfic, consider the different types of personalities you can find in a high school. There could be the over - enthusiastic teacher's pet who always gets in Alex's way. This character could be constantly trying to impress the teachers and expose Alex's secret activities. Or you could have a loner character who has a hidden talent for martial arts. They initially seem unapproachable but end up being a great ally to Alex when they discover his real identity.
