One possibility is that he would try to change the relationships around him. He might reach out to Sasuke earlier and prevent him from leaving the village. Also, he could be more strategic in dealing with the Akatsuki, since he'd know their plans in advance.
He'd be more confident. In his original Genin days, he was a bit of an underdog, but with his future memories, he'd know his potential. So he'd act more boldly.
In fanfiction, Naruto as a sensei often has a very unique dynamic with his genin team. He might teach them his own unorthodox ninja techniques, like his signature Rasengan. His experiences as a former underdog also shape how he trains his students, emphasizing perseverance and the power of friendship.
Overcoming challenges is also a typical theme. Genin face many difficulties like tough missions, rivalries with other genin teams. Fanfics explore how they deal with these challenges, like Naruto facing off against stronger opponents and finding ways to win through his determination and unique skills.
In such a fanfic, perhaps Naruto is overly nervous during the test. Maybe he fails the written part because he didn't study enough about basic ninja knowledge. For example, he could mix up different types of jutsu classifications. Another possibility is that he fails the practical part. He might lose control of his chakra while performing a simple jutsu, like the Clone Jutsu, which is crucial for genin. This could lead to him not creating enough clones or creating unstable ones that disappear quickly.
Well, one possible plot could be that Naruto fails the test due to his overconfidence. He might rush through the practical parts without properly showing his skills. For example, in the clone jutsu part, he could create clones that are too obvious and lack the finesse required. This would then lead to him having to face the disappointment of his peers and his own self - doubt, which could be a major part of the fanfic as he tries to overcome it and prove himself.
One popular 'genin Naruto fanfic' is 'The Genin Days'. It focuses on Naruto and his friends during their early days as genin, with lots of adventure and character development.
It's highly inappropriate. Naruto and Hinata's relationship in the official story is based on respect, friendship, and eventually love. But this should be presented in a way that is suitable for all audiences. Fanfic should focus on exploring their relationship in a positive, non - sexual way, like their mutual support, understanding, and how they grow together in the ninja world.
Maybe in a story where Naruto is tired of the restrictions within the village and wants more freedom to develop his ninja skills independently as a genin. He might face various challenges and adventures on his own.
Kakashi could also be a main character. He could be the one who has to deal with Naruto's failure in a different way than Iruka. Maybe he has to decide if Naruto is worth another chance. Also, Sakura could be involved. She might initially be disappointed in Naruto but then realizes that there is more to Naruto's failure than meets the eye and tries to support him in her own way.
