Well, Naruto's combat style would likely change a great deal. The Grand Priest's training might introduce him to different forms of combat and strategies. He could learn to sense ki or use it in some way. Also, his understanding of the world and different dimensions might expand. Maybe he would even be able to travel between different universes like the characters in Dragon Ball can. And his power level would be off the charts, making him a force to be reckoned with in the Naruto universe.
He would probably become extremely powerful. The Grand Priest is an incredibly powerful being in the Dragon Ball universe. Naruto, with his already impressive ninja skills and determination, could gain new abilities like energy manipulation or enhanced speed and strength.
He might gain extremely powerful and unique abilities. The high priest could teach him ancient and secret techniques that are not known in the normal ninja world. This would likely make Naruto even more formidable in battles, and perhaps give him a deeper understanding of spiritual or otherworldly powers.
If Naruto gets trained by Goku in fanfiction, it could be amazing. Goku's training often involves pushing the body to its limits. Naruto, who is already used to tough training, would adapt. He might gain the ability to fly like Goku, which would be a huge advantage in battles. Also, Goku's sense of justice and determination could rub off on Naruto, making him even more committed to protecting his village and friends.
In a fanfiction where Naruto is trained by dragons, his power would skyrocket. Dragons are known for their raw power and wisdom. Naruto could learn to harness the elements in ways he never thought possible. For example, he might learn to breathe fire like a dragon or use dragon - scale - like defenses. This training could also open up new storylines, like him having to protect the dragon realm from threats or using his new skills to face off against powerful enemies in the ninja world. His relationships with his friends and allies might also change as they see him in a new light with his dragon - trained powers.
In such a fanfiction scenario, Naruto might gain some really unique powers. The Shinigami could teach him about different forms of spiritual energy which could enhance his already formidable chakra. Maybe he'd learn to manipulate souls or gain a new level of perception.
In this fanfiction, Naruto might gain some unique and deadly water - style techniques from Zabuza. Zabuza is a master of assassination and water - style jutsu. So Naruto could become more stealthy and proficient in close - combat water attacks. He may also learn about the darker side of the ninja world from Zabuza, which could make him more cynical or more understanding of the different kinds of shinobi out there.
His personality might change in several ways. He would probably be more humble as he realizes the vastness of the power he is being exposed to. Also, he could become more of a mentor - like figure to the younger ninjas in Konoha. Since he is getting trained by such a powerful entity, he would have a greater sense of responsibility and would want to pass on his knowledge. He might also become more open - minded, as the Grand Priest's teachings could expose him to new ways of thinking and different cultures if the fanfiction has elements of different universes interacting.
In this fanfiction, Naruto might gain some unique jutsu skills from Itachi. Itachi is extremely powerful, so he could teach Naruto advanced genjutsu or ways to better control his chakra. For example, Naruto might learn how to quickly break free from strong genjutsu attacks, which would be a great advantage in battles against tough opponents.
Well, Naruto would probably become an even more formidable ninja. Batman's skills in strategy, detective work, and various combat techniques could enhance Naruto's abilities.

He could also pick up some of Batman's gadgets and use them in his own ninja way, like using batarangs as a new type of shuriken.
In this fanfiction scenario, Naruto might gain a whole new set of skills and perspectives. Nagato has powerful jutsu like the Rinnegan abilities. He could teach Naruto more about the nature of chakra on a deeper level. Naruto might also learn different combat strategies that are more in line with Nagato's style of fighting, which could make him an even more formidable opponent.
Well, Naruto would probably become an even more formidable ninja. Batman's strategic mind and combat skills could enhance Naruto's own abilities. He might learn new ways of stealth and planning, making him a more well - rounded fighter in the ninja world.
