Well, Naruto being trained by Onoki in fanfiction could lead to some interesting power - ups. Naruto's chakra control could be refined further. With Onoki's guidance, he might be able to use his chakra more efficiently when performing jutsu. This could result in him being able to perform more complex and powerful techniques without exhausting himself as quickly. And perhaps Naruto would also inherit some of Onoki's no - nonsense attitude towards enemies, making him a more intimidating opponent.
Naruto's character development under Onoki's training in fanfiction would be multi - faceted. Firstly, his patience would increase. Onoki is not one to tolerate rash behavior, so Naruto would have to learn to be patient. Secondly, his view of power would change. Instead of just relying on his brute strength and the Nine - Tails' chakra, he would start to appreciate the finesse and strategy that Onoki's earth - style jutsu represents. This would make him a more well - rounded ninja. He would also become more diplomatic, as Onoki would surely impart some of his wisdom about dealing with other villages and ninja. Overall, Naruto would transform from a head - strong young ninja into a more calculated and respected figure in the ninja world.
Well, one possible plot could be that Naruto grows up learning Earth - style jutsu from Onoki at a very young age. This gives him a different combat style compared to the original series. He might also inherit Onoki's no - nonsense attitude towards enemies.
His personality might be more serious. Since Onoki is a no - nonsense leader, Naruto could pick up that trait. He might be less impulsive and more calculating in battles.
Well, Naruto would probably gain some really unique magical abilities. Fairy Tail mages are known for their diverse magic, and Naruto could combine his chakra skills with something like Fire Magic or Celestial Magic. He might become even more powerful in combat, with new ways to attack and defend.
Naruto would gain better combat awareness. Kurama's experience in battles can be passed on to Naruto. He'll be able to read his opponents better, know when to attack and when to defend. This will make him a more formidable opponent in combat situations.
Yes, there are likely to be such fanfictions out there. The idea of Naruto being trained by Ichigo combines two very popular anime characters from different series. Fanfiction writers often come up with creative crossovers like this. You can try searching on major fanfiction platforms to find specific works.
One possibility in this fanfiction could be that Naruto gains new and unique combat skills. Monkey D. Dragon is known for his revolutionary ideas and powerful abilities in the 'One Piece' world. Under his training, Naruto might learn different ways of strategizing and approaching battles, perhaps incorporating some of the more unorthodox fighting styles from the 'One Piece' universe. This could lead to Naruto becoming even more formidable, not just in terms of his ninjutsu, but also in his ability to lead and inspire others in a different way, much like how Dragon has an impact on the 'One Piece' world.
Maybe Muu is a long - lost member of a powerful clan that has some special connection to Naruto's Uzumaki heritage. So he takes it upon himself to train Naruto to help him reach his full potential and also to preserve some ancient techniques or secrets related to their clans.
I'm not sure who the specific author of that fanfiction is. There are so many fanfiction writers out there that it's difficult to determine without more research.
