When it comes to interacting with Naruto's friends, Wei Ying would bring a whole new dynamic. He's used to a world full of danger and mystery, so he'd be a bit more cautious than some of Naruto's more carefree friends. But he'd also be very open - minded. For example, with Hinata, he'd be gentle and respectful, as he can sense her shy but strong nature. He'd share his knowledge of spiritual energy with her, which could help her with her Byakugan skills. And he'd be a great addition to their group, always coming up with new and creative ideas during their adventures.
He would probably get along well with Shikamaru. Shikamaru is laid - back but smart, and Wei Ying is also quite intelligent in his own way. They could sit around and strategize together, Wei Ying sharing his experiences from his own world. With Sakura, he might initially seem a bit strange to her, but once she sees his skills, she'd respect him. And he'd be really excited to learn about medical ninjutsu from her.
Wei Ying would be very curious about all of Naruto's friends. He'd be in awe of Choji's unique abilities and would probably try to find a way to combine it with his own powers. When it comes to Kiba and Akamaru, Wei Ying would be amused by their bond. He might try to play some tricks on them at first but then become good friends. His interaction with Ino would be interesting too. Ino is headstrong, and Wei Ying would either clash with her or they'd form a great team, depending on how they first meet.
If the OC is Naruto's brother, he would probably be very protective. He'd interact with Naruto's friends like Sasuke and Sakura in a friendly but also a bit of a bossy way. He'd want to make sure they're not getting Naruto into too much trouble. For example, he might be skeptical of Sasuke at first because of his brooding nature and would keep an eye on him when he's around Naruto.
The members of Root are often cold and calculating. They might initially try to manipulate Naruto's friends, like using false information to drive a wedge between them. For example, they could tell Sakura that Naruto is involved in something dangerous and illegal to make her doubt him.
Naruto would likely become more distrustful at first. He's always been so open and trusting of his friends, so this betrayal would shatter that. He might become more withdrawn, constantly second - guessing people's motives.
It would change it drastically. Naruto is known for his loyalty and friendship. If he were to kill his friends, it would shatter the image of the hero. His friends like Sasuke, Sakura, and Shikamaru are important to the overall story and relationships in the Naruto universe. Their deaths at Naruto's hands would create a huge rift among the other characters.
His friends might be initially shocked. But Naruto being Naruto, they would soon accept it. Sasuke might see Naruto's alien heritage as a new way to gain power and become more interested in working with him again. Sakura would be worried about the potential dangers it could bring to Naruto, and be more protective. Shikamaru might find it all too troublesome at first, but then start to strategize on how to use Naruto's newfound abilities for the village's benefit.
His relationship with Sasuke might be different. With Kurenai's influence, Naruto could be more understanding and patient, which might help him better deal with Sasuke's issues. His bond with Sakura could also change as he may approach her in a more mature way, having learned from Kurenai about relationships.
His friends might be a bit jealous at first. After all, Naruto is suddenly so interested in the Raikage. But they would also be supportive as they know Naruto is always looking to grow stronger. For example, Sasuke might be initially suspicious but then see the potential in Naruto learning from the Raikage.
His friends would be in shock. Kakashi would take charge of the situation. He would gather all the information about what Naruto was doing before he disappeared. Naruto's friends like Choji and Ino would use their respective skills to help in the search. Ino could try to use her mind - reading jutsu on people who were around Naruto before he disappeared. They would all be determined to find Naruto because he is an important part of their team and the village.
Sakura might be initially suspicious. She is a smart girl and would wonder about the butler's intentions. She might keep a close eye on him to make sure he doesn't harm Naruto in any way.
Sakura would probably be both disgusted and amused at the same time. She might scold Naruto for being so unhygienic at first, but then laugh at his silly antics.
