He might even develop some new forms or abilities that combine his ninja skills with Whis' teachings.
If Naruto were trained by Whis in a fanfiction, his physical strength and speed would likely skyrocket. Whis is known for his ability to enhance the capabilities of his trainees.

Maybe he'd be able to use ki in a way similar to how he uses chakra, creating some really interesting battle scenarios.
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.
If Naruto were trained by Whis in a fanfic, it could lead to some really interesting crossovers. Naruto's ninja skills combined with Whis' training could make him a force to be reckoned with. He might even develop some new forms or abilities that are a blend of the Naruto and Dragon Ball universes. For example, he could use his chakra in ways similar to how the Dragon Ball characters use ki, but with his own ninja - style twist.
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 speed would increase, enabling him to move faster than before. Mentally, he would learn new strategies from Whis, which would make his decision - making in battles more efficient.
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.
If Naruto is trained by RWBY fanfiction, his world view could be greatly expanded. RWBY has a different setting and set of values compared to Naruto's world. Naruto might start to see things from a different perspective, like how RWBY characters deal with the concept of Grimm and their own personal growth. This could lead to him evolving not just as a fighter but also as a person, and he might bring back some new ideas to his own village to improve it.
Well, in a fanfiction where Naruto is trained by Deidara, Naruto's creativity in combat would probably skyrocket. Deidara is all about his explosive art, and Naruto could learn to use chakra in ways he hadn't thought of before. Maybe Naruto would start using the environment in a more explosive way during battles, like turning rocks into mini - explosives like Deidara does with his clay. Also, Naruto might have to struggle with Deidara's nihilistic attitude towards life at times, but it could also make him more empathetic towards enemies with different outlooks in the long run.

He could learn more about the secrets of the ninja world from a different perspective, but also risk being influenced by their more amoral views.
In a fanfiction where Naruto is trained by Sanji, it could be really interesting. Sanji could introduce Naruto to the concept of using food as a source of energy in a more direct way. Naruto's rasengan might even get a new variation where he incorporates elements of Sanji's cooking. Maybe he could create a 'Rasengan - Spicy Curry' version. Also, Sanji's loyalty to his crew could inspire Naruto to be more dedicated to his village and friends.
