Naruto's chakra control could reach new heights. Whis's knowledge of energy manipulation could be applied to Naruto's chakra system. He could learn to condense his chakra more efficiently, making his attacks more powerful. Also, Naruto might develop new techniques that combine ninjutsu with ki - like elements. His Rasengan, for instance, could be infused with ki to create a more devastating attack.
His physical abilities would likely improve greatly. Whis could train Naruto to have better speed, strength, and agility, much like how he trains Goku and Vegeta in Dragon Ball. Naruto might also gain the ability to sense ki, which would give him an extra sense in battle.
If Naruto was raised by Whis, his abilities would be transformed in multiple ways. Firstly, Whis is known for his time - control training. Naruto could potentially learn to move at incredible speeds or even manipulate time on a small scale in battle. His stamina would also increase exponentially as Whis would likely put him through intense training regimens. Naruto's ability to learn new techniques would be enhanced as Whis could offer different perspectives on combat and energy use. His overall power level would skyrocket, and he might become a more versatile fighter, able to adapt to different types of opponents more easily.
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 raised by Slenderman in fanfiction, his abilities would change drastically. His chakra control might be influenced by Slenderman's otherworldly energy. He could gain the ability to manipulate the environment in a more spooky way, like making the air feel cold and heavy around his opponents. Also, his Rasengan might take on a different form, perhaps with a dark, swirling energy around it.
His physical strength might increase. Dwarves are often depicted as strong, and living among them could mean Naruto has to do a lot of physically demanding tasks like mining or lifting heavy objects. So, he'd likely have more brute force.
His abilities would likely become more brutal. The Espada are known for their raw power and direct combat styles. Naruto might not develop his signature jutsu like the Rasengan in the same way. Instead, he could focus more on melee combat and dark - based energy attacks similar to what the Espada use.
He might gain the ability to transform like Saiyans do. This could give him different power levels and appearances during battles, making him a more versatile fighter.
His abilities would likely become more focused on close - range combat and self - preservation. Hidan is good at getting up close and personal in a fight, so Naruto might develop similar skills. Also, he could learn some of Hidan's unique techniques related to his immortality, although it's not clear if Naruto could fully replicate them. But overall, his combat style would be less about flashy long - range attacks and more about brute force and survival.
He might develop better water - based jutsu skills. Since Ame is a rainy place, he'd have more opportunities to practice with water. His stealth abilities could also be enhanced as Ame's environment might require more sneaking around.
His sense of smell would likely improve significantly. Since the Inuzuka clan has a strong connection with their ninja dogs and are known for their enhanced sense of smell, Naruto would be trained in this area. This could help him in tracking enemies or finding hidden objects much more easily than in the original story.
His combat abilities would likely be more refined. Female Itachi would train Naruto in precision and stealth, enhancing his skills in close - quarters combat. He might also be better at genjutsu as Itachi was a master of it.
His abilities would likely be much more powerful and darker. He might be able to access the Ten - Tails' full power easily. His chakra would be on a completely different level, enabling him to perform extremely powerful jutsus without much effort. He could also have some unique abilities related to the Ten - Tails, like the ability to control the Bijuu more directly.
