One plot twist could be that the early use of shadow clones makes the Akatsuki target him sooner. They see his potential as a threat and decide to eliminate him while he's still relatively weak. Another could be that Orochimaru becomes interested in Naruto earlier and tries to persuade him to join him, seeing the power he could gain from Naruto's early - developed abilities.
Perhaps a plot twist could be that the shadow clones develop a sort of sentience earlier. They start to act independently and form their own little 'clan' within Naruto. This could lead to some really strange and unique situations where Naruto has to deal with his own clones having different personalities and desires, and he has to figure out how to control them or work with them in a new way.
Naruto learning shadow clones early could also have an impact on his confidence. Success in using the jutsu early on would boost his self - esteem. He'd be more likely to take on challenges and face enemies without hesitation. This new - found confidence could lead him to be more creative in combat situations, coming up with new strategies that combine the use of shadow clones in unexpected ways.
One possible plot twist could be that Naruto discovers he has a natural affinity for a special type of metal that is only found in a hidden realm. This metal has unique properties that can enhance his ninja tools in unexpected ways. Another could be that the smithing skills he learns are actually part of an ancient prophecy. It was foretold that a ninja with Naruto's spirit would master smithing to create a weapon that could save the ninja world from a great threat that is yet to come.
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 possible plot twist could be that his heritage is linked to an enemy he thought was unrelated. So he has to reevaluate his views on the whole conflict.
One idea could be a fanfiction where Naruto uses his shadow clones in a cooking competition. Each clone has a different cooking style, and they work together to create a masterpiece. Another could be about shadow clones being used in a music concert, with each clone playing a different instrument.
One interesting storyline could be a fanfic where a character uses shadow clones to explore different paths in life simultaneously. For instance, one clone might pursue a path of strict ninja training, another could focus on learning about the village's history, and the original character gets to experience the knowledge and skills gained from all these different 'lives' of the clones.
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.
One possible plot twist could be that Naruto's early mastery of the Rasengan catches the attention of Orochimaru much earlier. Orochimaru might see Naruto as a more immediate threat or a potential vessel with even greater potential than before. This could lead to more direct and dangerous attacks on Naruto, forcing him to grow even faster in his combat skills and strategic thinking.
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.
