If Naruto was trained by Whis in fanfiction, his power would reach new heights. His already powerful Sage Mode could be enhanced. Maybe he could enter a new 'Ultra Sage Mode' where his physical and chakra abilities are boosted even more. His shadow clone jutsu could be modified. Instead of just creating clones for distraction or extra attacks, he could create clones with different abilities, like some clones having the ability to sense ki better than the others. This would make his combat strategy more diverse and unpredictable.
Naruto's abilities would be transformed. He might gain the ability to sense ki like in the Dragon Ball universe. This could give him an edge in battles as he could detect enemies from a greater distance. His physical endurance would also improve, enabling him to fight for longer periods without getting tired. His ninjutsu could be combined with Whis - like techniques, creating new and deadly attacks.
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.
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.
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 speed would increase. Goku Black is very fast, and his training could make Naruto move at blistering speeds. Also, Naruto's power attacks would be stronger. Goku Black's training methods would push Naruto to new limits.
If Naruto was trained by Sun Wukong, his physical abilities would likely improve greatly. Sun Wukong is known for his superhuman strength, speed, and agility. Naruto could learn to move faster and hit harder. Also, Sun Wukong's ability to transform might influence Naruto. Naruto already has his own transformation abilities with the Nine - Tails, but he could learn new forms or ways to transform more effectively from Sun Wukong.
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.
Well, if Naruto is trained by Whis in fanfiction, it would be a wild combination. Naruto's already strong willpower and determination would be further enhanced by Whis' training. Whis could help Naruto unlock new forms or levels of power that he never thought possible. For example, Naruto might develop a form that combines his chakra with the kind of energy manipulation Whis teaches. His rasengan could become something far more powerful, perhaps with an added energy blast like a ki - based attack. And his ability to sense opponents could be refined to an even greater degree, allowing him to anticipate attacks much earlier.
Well, Naruto would probably become extremely powerful. Whis' training methods are very unique and strict. Naruto, with his already strong will and determination, could learn new combat techniques and gain a better understanding of energy control. He might even develop some new forms or abilities that combine his ninja skills with Whis' teachings.
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 character would grow in terms of maturity. Facing the challenges of Whis' training, Naruto would gain a deeper understanding of his own power and limitations. He would also become more humble as he realizes how much more there is to learn in the wider multiverse. Moreover, his sense of responsibility would expand as he aims to use his new - found abilities for the greater good not just in his own ninja world but potentially across different realms.
