Naruto's abilities would undergo a major transformation. Shao Kahn's training would probably focus on toughening Naruto up both physically and mentally. Physically, Naruto would gain more muscle mass and become stronger, which would enhance his taijutsu. Mentally, he would learn to be more strategic in a different way than in the ninja world. His chakra abilities would be refined. Instead of relying mainly on his shadow clones and rasengan, he could learn to infuse his chakra with different elements in new ways, inspired by Shao Kahn's combat techniques. This would make Naruto a more unpredictable and powerful opponent, as he would have a whole new set of skills and a different approach to combat.
His physical abilities would likely improve a great deal. Shao Kahn could teach Naruto more about brute force and raw power, enhancing Naruto's already impressive strength. His combat skills would also become more diverse, incorporating some of Shao Kahn's signature moves.
If Naruto is trained by Shao Kahn in fanfiction, it would be a wild mix of two different fictional universes. Naruto, who is used to the shinobi way of life, would be exposed to Shao Kahn's world of Outworld. Shao Kahn could introduce Naruto to more aggressive and perhaps darker forms of combat. This might change Naruto's personality a bit, making him more of a no - nonsense fighter. Also, Naruto might learn some new ways to enhance his physical strength, which could be a great addition to his existing skills.
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.
Naruto would probably develop a more diverse set of combat skills. With Edward's training, he could incorporate more acrobatic maneuvers into his fighting style, similar to how Edward moves on ships and during battles. His perception skills would also be sharpened as he learns to read the intentions of his opponents in different ways. For example, instead of relying solely on his ninja senses, he could learn to read body language like a pirate. His ability to adapt to new environments would be enhanced as well, since Edward has experience in various terrains and situations.
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.
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 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.
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.
