If adopted by Shino in fanfiction, Naruto's character could change in several ways. For one, he'd likely become more attuned to nature, since Shino has a strong connection to the bugs in nature. Also, his fighting style might become more strategic and less brute - force - oriented. Shino could teach him to use his surroundings and opponents' weaknesses better. And Naruto's sense of family might shift. Instead of always longing for the acceptance of the village as a whole, he'd have a more personal family unit with Shino, which could make him more content and less desperate for validation from others.
His confidence could take on a different form. Naruto is usually loud about his confidence, but with Shino as his adoptive father, he might develop a quieter, more self - assured confidence. Shino could show Naruto that true strength doesn't always need to be shown off. This would lead to Naruto being more of a thinker and less of a show - off in combat situations, which would be a significant change to his character.
Well, one possibility is that Shino, with his calm and observant nature, could teach Naruto a different way of looking at things. Maybe he'd train Naruto in his unique bug - related jutsus, which would give Naruto an edge in combat. Also, Shino's quiet support could help Naruto deal with his inner demons in a more introspective way.
In fanfiction, Naruto and Shino's friendship can be really interesting. Naruto's exuberant personality contrasts with Shino's more reserved nature. For example, Naruto might be the one to drag Shino into all sorts of adventures, while Shino would use his intelligence and bug - related skills to get them out of trouble. Their friendship could also develop over training sessions, with Naruto learning about Shino's unique abilities and respecting him more for it.
In a fanfiction regarding Shino's eyes, his eyes might be the key to an ancient shinobi technique. For example, his eyes could unlock a hidden jutsu that was lost for centuries. This jutsu could be related to insect control in a more profound way, like being able to communicate with all insects on a spiritual level, not just the ones he summons. This would give him a huge advantage in both intelligence - gathering and combat.
In some fanfictions, Shino's time travel forces him out of his comfort zone. He may be more reserved in the original series, but when he travels through time, he has to be more outspoken to get things done. For example, if he travels back to a time when his clan was in trouble, he has to be more assertive in protecting them. This makes him grow as a character, becoming more confident in his abilities.
Well, in some fanfiction, their friendship is shown as a slow - burning one. Naruto doesn't quite understand Shino at first because of his bug - like appearance and quiet ways. But as they work together on missions, Naruto begins to see Shino's loyalty and strength. Shino, on the other hand, admires Naruto's determination.
They could start by sharing common goals. For example, they both want to protect Konoha. Working towards this goal side by side can bring them closer. They might have conversations during their guard duties about their dreams and fears.
Naruto's character would likely become more confident. With a family structure provided by Mikoto, he would feel more secure. He might also become more mature as he is exposed to the Uchiha way of life. For example, he could learn discipline and patience more quickly. His understanding of the ninja world would expand as he learns from Mikoto about different clans and their relationships.
Naruto would likely become more calm and calculating, taking after Shikaku's personality traits.
Naruto would likely become more reserved. Since Kisame is not as expressive as some of Naruto's friends in the Leaf Village, Naruto would pick up on that. His fighting style would also change. He'd probably be more stealthy and calculating, learning from Kisame's experience. For example, instead of his usual head - on attacks, he'd start to use more misdirection and ambush tactics.
His character might become more refined. Yugao's influence could lead to Naruto having better manners and a more composed demeanor.
