Well, for one thing, Naruto would likely become an even more formidable fighter. Yoda's training methods are quite different from what Naruto is used to in the Hidden Leaf Village. Yoda could impart his knowledge of the Force, which might interact in strange and interesting ways with Naruto's own chakra. Maybe Naruto would start using a lightsaber - like weapon in addition to his kunai and shuriken. His mental and spiritual growth would also be significant, as Yoda is known for his deep wisdom. This could change Naruto's approach to his enemies and his friends, making him more of a spiritual and philosophical ninja - Jedi hybrid.
Well, perhaps a plot twist could be that during the training, Anakin discovers that Yoda has a secret connection to the Sith. This would completely shatter his view of the Jedi Order and his trust in Yoda, leading to a very different path for his character.
Anakin might develop more self - control earlier. Yoda's wisdom and unique training style could help him better understand his emotions and not be so easily swayed by fear, which was a major factor in his fall to the dark side in the original story.
In a Star Wars fanfic where Anakin was trained by Yoda, Anakin might have better control over his emotions. Yoda's wise teachings could have steered Anakin away from the dark side. He might have learned more about the Force in a balanced way, rather than being influenced by Palpatine's dark whispers.
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.
Anakin's skills would develop more holistically. Yoda could teach him to use the Force in subtler ways, not just for combat. His lightsaber skills might become more refined in a different style, influenced by Yoda's own unique approach to combat.
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.
