Naruto's abilities would change significantly. Firstly, his chakra control would be on a whole new level. Growing up in a temple, he'd have ample time for meditation and self - discovery, which would lead to better chakra manipulation. His taijutsu could be more like a martial art form practiced in the temple, emphasizing fluidity and economy of movement. In terms of ninjutsu, he might be able to draw on the spiritual energy of the temple, creating jutsu that are not only powerful but also have a calming or purifying effect. His sensory abilities would also be sharpened as he'd be attuned to the subtle energies around him, making him better at detecting enemies and their intentions.
His chakra control would probably be better. In a temple, he might learn meditation techniques that help him master his chakra more effectively. Also, his physical abilities could be more refined in terms of balance and grace, like a monk's movements.
Naruto's combat style would be more refined. Sakumo was a highly skilled ninja, and he would teach Naruto better swordsmanship skills perhaps. Naruto's taijutsu could also be more precise and calculated. Also, Naruto might develop better chakra control earlier, as Sakumo could instill in him the importance of efficient chakra usage from a young age.
Naruto could have a greater control over his chakra. Since Kushina would be there to guide him, he would likely avoid some of the pitfalls he faced in the original story. His physical strength might also be enhanced as Kushina could train him in ways that utilize his Uzumaki bloodline more effectively.
Naruto's ability to control the Nine - Tails would be enhanced. Since the Sage has a deep understanding of the tailed beasts, he could teach Naruto how to fully harness the power of the Nine - Tails without the usual struggle. This would make Naruto not only stronger but also more in tune with the beast's power, allowing him to use it more effectively in combat. He could also potentially communicate with the Nine - Tails on a much deeper level, leading to new forms of cooperation between them.
His physical abilities would be enhanced. Constantly running, climbing, and fighting in the forest would make him stronger and more agile. His stealth skills would be top - notch as he'd have to hide from the forest's predators.
He'd probably be more confident. Kushina's love and support would make him feel secure. He wouldn't have that same loneliness - driven need for attention like in the original story.
His personality would likely be more stoic. Kisame is a rather reserved and tough character, and growing up with him would probably make Naruto less exuberant. He might not be as quick to trust others as he is in the original story.
Naruto's training would likely be more intense and survival - based. Zabuza was a tough and unforgiving trainer in his own right. He might push Naruto to his physical and mental limits from a young age, making Naruto more resilient in combat. For instance, instead of the relatively structured training in the Hidden Leaf, Naruto could be thrown into real - life combat situations early on to learn quickly.
His sense of humor would be different. Anko has a dry and sometimes dark sense of humor. So Naruto might crack jokes that are a bit more on the sarcastic side and less goofy. For instance, instead of his usual over - the - top pranks, he might play more calculated and sneaky pranks inspired by Anko. Also, he would be more confident in his own abilities from an earlier age, as Anko would encourage him to trust his instincts.
Mentally, Harry would be more in tune with the Force. This would give him an edge in sensing danger and the intentions of others. His ability to resist the Imperius Curse might be stronger due to Jedi mental training. Instead of using spells for divination, he could use the Force to foresee events. And his telepathy - like abilities from the Force could be used in place of some magical communication spells.
Her Semblance could be more destructive. Instead of using it mainly for mobility and quick attacks, it might be used to cause widespread chaos. For example, instead of just dashing in and out of battles, she could use her speed to create tornado - like effects that cause more damage to her enemies.
