Obviously Naruto would be one of the main characters. Since it's set in an academy, his classmates like Sasuke and Sakura would likely also be important characters. The academy teachers, such as Iruka - sensei, would probably play significant roles as well.
The main character is Naruto without a doubt. In the academy setting, his friends and rivals are key. Shikamaru, who is known for his intelligence, could be an interesting character in this fanfiction. He might be observing Naruto's op abilities and trying to figure out how to use his own skills to keep up. Ino could also be involved, perhaps having some sort of interaction with Naruto regarding his new - found power in the academy environment.
I'm not sure specifically as there could be many different plots in a 'naruto is op academy' fanfiction. It might involve Naruto having overpowered abilities in an academy setting, like being able to use high - level jutsu easily while others struggle. Maybe he outperforms his classmates in combat training or academic studies due to his new - found op (overpowered) status.
It's hard to say exactly as it's fanfiction, but it could include Naruto - like characters with enhanced, god - like powers. Maybe some new characters created specifically for this fanfic who are leaders or star students in the godlike academy.
Obviously, Naruto and Sakura are the main characters. Naruto, with his determination and unique skills, and Sakura, with her intelligence and growing strength in the academy setting.
In this fanfiction, Naruto is the central figure. Hinata could be another main character. She has always had a crush on Naruto, and in the 'Handsome Academy', she could be shyly trying to get closer to him while also improving her own charm. Kakashi could be a teacher at the academy. He has his own unique charm and could be guiding the students in the ways of the academy, which includes both academic and 'handsome - related' teachings.
It could be Naruto and Ichigo. Since it's a crossover of the two series, these two popular protagonists would likely play important roles in the fanfiction.
Naruto himself is extremely popular in Naruto Academy Fanfiction. His determination and unique personality make him a central figure in many stories. Sasuke is also popular as his rival, and many fanfictions explore their relationship further within the academy setting.
The bijuu are the main characters as they are the focus of the 'goes to Yuki Academy' part. However, depending on how the story unfolds, there might be some side characters like the academy's janitor who has some secret knowledge about the bijuu and ends up helping them in unexpected ways, but still, the bijuu are the central figures.
Obviously Naruto would be one of the main characters. He would be the one bringing his ninja world charm and skills to Gaia Academy. Another could be a student at Gaia Academy who befriends Naruto early on, like a smart girl who helps him understand the academy's rules and curriculum.
Popular characters include Shikamaru. He could be in a fanfiction where he pretends to be even more lazy than he really is to deceive his opponents or teachers. Ino might be a character who pretends to be best friends with someone she doesn't really like to gain some information. And Kiba, along with Akamaru, could pretend to be a different type of ninja - animal duo to surprise their classmates during a practical exam.
I'm not sure specifically who the main characters are in Rocket Academy Fanfiction as it depends on the individual stories written by fans. But it could be students, teachers, or even administrative staff within the Rocket Academy.
