His combat abilities would become more diverse. Madara could teach him new forms of taijutsu and ninjutsu. For example, Naruto might learn some of Madara's signature space - time ninjutsu, which would give him an edge in battles. His chakra control would also improve as Madara is very proficient in chakra manipulation.
Naruto's abilities would change in multiple ways if trained by Madara in a fanfic. His perception of the world around him during combat would become sharper. Madara could teach him how to sense opponents in a more detailed way, similar to how Madara was able to detect threats from afar. Naruto's Rasengan and other signature moves might be modified. Madara could show him how to add more power or new elements to these moves. His ability to endure in long - term battles would also increase as Madara would likely train him to have greater stamina. And his connection to the Nine - Tails would potentially be enhanced in ways that we can't even imagine, as Madara has a lot of knowledge about tailed beasts.
For Naruto, being trained by Madara could mean he learns how to counter Uchiha - specific techniques more effectively. His physical strength might also increase due to the intense training. Sasuke would be able to better harness his hatred and turn it into a more focused power source. Madara's teachings could expose them to ancient jutsu and knowledge that would give them an edge over their enemies. Their teamwork might also be affected, as they would both be influenced by Madara's way of thinking.
His abilities would be enhanced greatly. He could have better chakra control. For instance, he could use chakra more efficiently and might be able to perform jutsu with less effort. His physical abilities like strength, speed and agility would also improve. He could run faster than normal ninjas and jump higher.
If Naruto was trained by Danzo and joined Team 7 in a fanfic, his abilities would change significantly. Danzo's training would probably give him a more strategic mindset. He could be more proficient in using weapons and stealth. In Team 7, he'd learn to coordinate with Sasuke and Sakura. His chakra control might improve in different ways, and he could develop new jutsu that are a combination of what he learned from Danzo and what he discovers while on missions with Team 7.
Naruto would likely become more serious. Madara's influence would probably make him less impulsive. For instance, he would think twice before charging into battle without a proper plan.
Naruto's abilities would change significantly. Ichigo has unique spiritual powers, and through his training, Naruto might develop a form of 'spiritual chakra'. His ninjutsu could become more powerful as he combines the new understanding of energy with his existing chakra control. Also, Naruto's combat strategy would shift as he learns from Ichigo's more direct and aggressive fighting style.
If trained by Sanji, Naruto's sensory abilities could get better. Sanji has a good sense of smell which he uses in various situations. Naruto could learn to use his senses more effectively, not just relying on his chakra senses. Also, Naruto's ability to endure pain might increase. Sanji has endured a lot in his life, and he could pass on some of that mental toughness to Naruto, allowing him to push through tougher battles and train harder without getting worn out as easily.
His confidence might increase even more. Female Madara is a strong figure, and being trained by her would give Naruto a sense of having access to greater power. So he would be more self - assured in his actions.
Naruto would probably develop a more diverse set of combat skills. With Edward's training, he could incorporate more acrobatic maneuvers into his fighting style, similar to how Edward moves on ships and during battles. His perception skills would also be sharpened as he learns to read the intentions of his opponents in different ways. For example, instead of relying solely on his ninja senses, he could learn to read body language like a pirate. His ability to adapt to new environments would be enhanced as well, since Edward has experience in various terrains and situations.
In a fanfic scenario where Naruto has Madara's eyes, it would be a game - changer for his abilities. First off, the basic Sharingan abilities would boost his combat awareness. He'd be able to react faster and with more accuracy. The more advanced forms of the Sharingan, like the Eternal Mangekyo Sharingan if he were to achieve it, could grant him access to powerful techniques. For example, he might be able to use space - time ninjutsu similar to Madara. This would not only change the way he fights but also how he strategizes in battles, as he would have a whole new set of tools at his disposal.
His relationship with Sasuke might be affected. Naruto might approach Sasuke differently, with new strategies learned from Zetsu. He could be more secretive about his intentions towards Sasuke, which might either make Sasuke more curious or more distrustful. With his friends in Konoha, they might be a bit wary of Naruto at first because of his new training source. But once they see that Naruto is still on their side, they would support him.
