In the 'Naruto grows horns' fanfiction, how would his friends react to his new appearance?

Sasuke might be initially suspicious. Given their complex relationship, Sasuke would likely want to know the real reason behind Naruto's identity change. But once he understands the motives, he might respect Naruto's decision if it's for a good cause.

Sasuke, who has his own complex relationship with Naruto, would probably be in denial at first. He's seen Naruto as this strong - willed person, and the idea of him having schizophrenia would be hard to accept. But as time goes on, he would become more protective. He might train Naruto in ways to control his mind during the episodes, using his own experiences of mental discipline. As for Kakashi, he would be empathetic. He has his own traumas, and he would do his best to support Naruto, maybe sharing his own stories of dealing with difficult mental states.

His friends' reactions would vary greatly. Shikamaru would be impressed but also concerned about the implications. He'd start thinking about the strategic advantages and disadvantages of Naruto having this power. Choji would be excited and would see Naruto as an even greater protector of the village. Ino would be a bit scared at first, seeing how Naruto's power seems almost uncontrollable when he first shows it. But as she realizes that Naruto has it under control, she would be more supportive. And Hinata would be the most supportive of all. She would be there for Naruto, believing in him no matter what, and would offer her gentle words of encouragement.

Hermione would probably be both curious and concerned. She'd want to research immediately to find out how and why this happened. Ron, on the other hand, might be a bit more in awe at first. He'd likely make some jokes about Harry looking like a strange bird, but still be supportive.

Hermione would probably be very curious at first. She'd immediately start looking through all her books to find any information about such a strange transformation. Ron, on the other hand, might be a bit more freaked out. He'd probably make some jokes at first to cover up his unease, but then he'd be there to support Harry. Ginny would likely be concerned but also find it kind of cool and would try to help Harry get used to his new wings.

His friends from Team 7, like Kakashi, would feel responsible for Naruto's situation. Kakashi would likely use his resources to find a proper shelter for Naruto. Shikamaru and the others might come together to form a sort of support group for Naruto. They would pool their resources, like money and food, and also try to cheer him up by sharing stories and jokes.

Sasuke would be extremely enraged. He has a deep bond with Naruto, and Naruto's death would likely send him on a quest for revenge against Konoha. He might see it as a betrayal of everything Naruto stood for and fought for.

Shikamaru would probably be the most vocal against it. He's a lazy but intelligent character. He would see Naruto's plan as too troublesome and dangerous. He'd tell Naruto that there are too many unknowns and that it's not worth the risk. He might even try to enlist the help of Kakashi or other more experienced ninjas to stop Naruto from going through with it.

His friends would be very shocked at first. Sasuke, for example, might be suspicious of this new Naruto. But once he realizes that Naruto is still the same at heart, he would start to accept it. Sakura would probably be worried about Naruto's well - being and try to find a way to reverse the change if possible.

Sakura might be a bit confused at first. She's focused on her medical ninja training and Naruto's sudden interest in Lunney seems out of left field. But she would probably be supportive in the end, especially if Naruto could show her how Lunney's ideas could be relevant to their lives. Sasuke, on the other hand, would likely be dismissive. He has his own goals and Naruto's newfangled interest might seem like a distraction to him. However, if Naruto could prove that Lunney's concepts could help in their fight against common enemies, Sasuke might change his tune.
