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.
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.
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.
In a fanfic where Naruto is trained by Madara, Naruto might gain some extremely powerful and unique jutsu. Madara is a very skilled and experienced shinobi. He could teach Naruto some ancient and forbidden techniques that are not known in the regular Naruto world. This could make Naruto an even more formidable opponent, perhaps with a new style of combat that combines his own natural abilities with Madara's dark and powerful knowledge.
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.
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.
Well, in such a fanfiction, Madara's training might enhance Naruto's physical strength. He could teach Naruto some advanced Uchiha techniques which Naruto can combine with his own Uzumaki powers. For example, Naruto might learn better chakra control from Madara, enabling him to use his Rasengan more effectively and with less chakra waste.
His speed would increase a great deal. Whis is very fast and could teach Naruto how to move more swiftly. Also, Naruto's chakra control might be enhanced, allowing him to perform more complex jutsus with less effort.
If Naruto was trained by Shang Tsung, his abilities would likely become much more diverse. Shang Tsung has a lot of knowledge about different fighting styles and dark magic. Naruto might learn some sneaky and underhanded tactics which are not typical in his usual ninja training. His chakra control could also be enhanced in new ways, perhaps to mimic some of Shang Tsung's shape - shifting abilities on a basic level. For example, he could use his chakra to change his appearance slightly to deceive opponents, adding a whole new dimension to his combat skills.
