Expect their friendship/rivalry to be at the center. The fight is not just about who is stronger physically. It's about their bond. In fanfiction, the writers often play with the idea of whether they can still be friends after such an intense battle. It's a very emotional aspect.
Well, in a typical Lee vs Neji fanfic during the Chunin Exam, one key plot point could be Lee's determination to prove himself. He's always been the underdog, but he has an unwavering spirit. Neji, on the other hand, is the prodigy. Their fight might focus on Lee's unique fighting style, like his use of the Eight Gates. Maybe Lee manages to open some gates early on, shocking Neji and the audience. This could lead to Neji re - evaluating his views on hard work vs. natural talent.
It could be quite challenging for them. Without Naruto's unique skills and strategies, they might have to rely more on their own teamwork and individual strengths.
Maybe he realizes the exam is too dangerous or he discovers some unfairness in it. In the original Naruto story, Naruto has faced many difficulties and moral dilemmas during the Chunin Exam. So in the fanfiction, similar situations might push him to quit.
In such a fanfiction, Naruto might use his new and improved Rasengan techniques that he's been secretly practicing. Sasuke, on the other hand, could unveil some new Sharingan powers. It could be a battle full of intense jutsu exchanges and emotional turmoil as they both strive to prove themselves in the Chunin Exams.
In a Chunin Exam Lee vs Neji fanfic, Lee's character development can be seen as he faces Neji. Lee starts off as the plucky underdog. As the fight progresses, he shows more and more of his tenacity. He may grow in confidence as he lands blows on Neji. Neji, who starts as a rather cold and aloof character, might start to respect Lee more as the fight unfolds, which is a big step in his character development.
One possible scenario could be that Sasuke returns just in time to see Sarada's skills in the Chunin exam. He might be filled with pride as he watches her fight. Sarada, on the other hand, would be motivated to show her father what she has learned. It could also be a moment of emotional reunion, especially if they haven't seen each other for a while.
One possible fanfiction could be about Sakura showing off her improved medical ninjutsu skills during the Chunin Exam. She might use her skills to quickly heal her teammates during battles, surprising everyone with her growth.
In this fanfic, Naruto and Sasuke might have an even more intense battle. Naruto could use his new jutsus that he learned from Jiraiya, like the Rasengan variations. Sasuke, on the other hand, might show off his improved Sharingan skills. Maybe he could even start to unlock some of the deeper powers of the Sharingan during the fight. And their fight could also attract the attention of other characters, like Sakura, who might be worried about Sasuke but also amazed by Naruto's growth.
One exciting moment could be when Naruto first unleashes a new jutsu. It would catch Sasuke off - guard and show his growth. Another moment might be when Sasuke activates a new level of his Sharingan, making the battle more intense. Also, if Naruto manages to break through Sasuke's cold exterior and make him remember their bond, that would be a great moment.
