Naruto's character would change significantly. He'd likely be more self - assured as he grows up under Beerus. He may not have the same sense of community as he did in Konoha since Beerus is more of an individualistic being. He might also be more patient and less likely to jump into action without thinking, having learned from Beerus' more calculated ways.
If Naruto was raised by Beerus in fanfiction, his character would transform in multiple ways. He would inherit some of Beerus' nonchalance towards minor things. His boisterousness might be toned down a bit. Instead of always seeking approval from others like he did in Konoha, he'd be more self - reliant. He would also have a different view on power. In Konoha, power was about protecting the village and friends, but with Beerus, power might be more about self - preservation and dominance in a different sense. His sense of humor might also change, becoming more sarcastic like Beerus at times.
His personality might be more rough around the edges. Kumo has a tougher environment, so he'd likely be more assertive.
His character would become more edgy. He might be more into self - expression through art and destruction like Deidara. Naruto's positive and naive side could be toned down a bit.
Naruto's character would become more in tune with Arachne's characteristics. He could be more patient and calculating. Since Arachne is often associated with webs and traps, Naruto might be more strategic in his battles and less impulsive. He may also have a different sense of loyalty, not being as blindly loyal to a village as he was in the original story.
He'd be more cynical. Jenova is a malevolent force, so Naruto would likely lose his optimistic outlook.
Naruto's personality would likely be more reserved. Instead of being the loud and boisterous Naruto we know, he might be quieter, observing from the shadows more often. Since foxes are often solitary animals, he might have a harder time making friends initially. But on the positive side, he'd be extremely adaptable, able to survive in tough conditions just like a fox in the wild.
He'd be more cynical. Orochimaru's ways would make Naruto question the goodness in people.
Naruto's character would change a great deal. Since Acnologia is a powerful and somewhat menacing figure, Naruto would probably be more aggressive. He might not value the same things as the original Naruto, like the bonds of friendship within the village. Instead, he could be more focused on his own strength and survival. He might also be more distrustful of others, having grown up under the tutelage of someone like Acnologia.
Naruto would become more of an anti - hero. His actions wouldn't always be in line with the traditional good - guy values. He might break rules more often and be less concerned about what others think of him. His appearance might also change, perhaps taking on some of Joker's flamboyant or menacing style.
If Naruto was raised by Slenderman in fanfiction, his abilities would change drastically. His chakra control might be influenced by Slenderman's otherworldly energy. He could gain the ability to manipulate the environment in a more spooky way, like making the air feel cold and heavy around his opponents. Also, his Rasengan might take on a different form, perhaps with a dark, swirling energy around it.
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.
