One interesting aspect is seeing Naruto's determination. In the original series, he is known for his tenacity in becoming a great ninja. In these fanfictions, that same determination is applied to his learning, which is inspiring. Another aspect is how the fanfiction can fill in gaps in the original story about his education.
One popular 'Naruto learns to read and write early' fanfiction might be 'Naruto's Early Education'. It focuses on how Naruto overcomes his initial difficulties in learning these basic skills in a creative way. Another could be 'The Young Naruto's Literacy Journey' which shows how his friends and mentors play a role in his learning process.
In fanfiction, if Naruto learns Rasenshuriken early, he might become a much stronger shinobi much earlier. He could use it to surprise his opponents and gain an edge in battles. For example, he could have used it against Orochimaru during their early encounters and potentially changed the outcome of those battles.
One possible consequence is that he might become more confident earlier. With the Rasengan in his arsenal sooner, he could face opponents more bravely in the early stages of his ninja journey. This newfound power could also make him a target for stronger enemies who see him as a potential threat.
In this kind of fanfiction, Naruto might become much stronger early on. He could use the Kage Bunshin to train in ways he couldn't before. For example, he could send clones to learn different jutsu simultaneously, which would greatly accelerate his growth as a ninja.
Well, one possible plot development could be that Naruto immediately starts training in the unique abilities related to his heritage. For example, if his heritage involves some special jutsu, he might quickly master it and use it to gain recognition in the village. This could change his relationship with his peers as they see him in a new light.
He might become more confident. Knowing his heritage early gives him a sense of belonging that he lacked before. So instead of constantly seeking attention in a brash way, he could be more self - assured and focused on his new - found purpose.
Well, one possibility is that he becomes much stronger early on and is able to take on tougher opponents. Maybe he could save his friends from more dangerous situations sooner. For example, he might be able to defeat Orochimaru earlier in the story, preventing him from causing more harm to Konoha.
One possible plot could be that Naruto discovers an ancient scroll that has a simplified version of the Rasengan technique. He spends days secretly practicing it in the forest, facing initial failures but gradually getting the hang of it. With his new - found skill, he surprises his friends and even manages to use it in a sparring match against Sasuke, changing the dynamics of their rivalry early on.
His confidence would likely skyrocket. Having such a powerful jutsu early on would make Naruto feel more capable and less like the underdog. He might be more assertive in his actions and decisions.
