Kakashi would be more reserved but still show his support. He might give Sasuke some advice on being a father based on his own experiences with his team. Shikamaru would be practical, thinking about how the baby will affect the village's future and offering some logical solutions to any potential problems that might come up.
At first, Naruto is probably shocked and confused. He might not understand why the village would take such a harsh step just for hurting Sasuke. He may feel betrayed, especially if he thought he had friends and allies in the village.
Well, Naruto might be furious. He's always been protective of Sakura. He'd probably drop everything he's doing and go after Sasuke to rescue Sakura. Naruto has a strong sense of justice and loyalty, especially towards his friends. And Sakura is one of his closest friends, so he won't stand by and let her be in danger.
She could be heartbroken. Sakura has always loved Sasuke deeply, so his leaving for Naruto would be a huge blow to her. She might initially be in denial, not believing that Sasuke would choose Naruto over her.
A fanfic could explore a scenario where Sasuke decides to teach Naruto some basic Sharingan techniques. Despite Naruto not having the Sharingan, Sasuke believes that Naruto's ability to learn quickly and his unique chakra could allow him to adapt some of the Sharingan's skills. This would strengthen their friendship as they train together and Naruto starts to understand Sasuke's power on a deeper level.
Kakashi would be more of a supportive figure. He has seen Naruto and Sakura grow up, and he would likely be happy for them. He might offer some advice to Naruto on how to handle this new relationship, especially considering the challenges they might face as ninjas. For Sakura, he could give her words of encouragement to be true to her feelings.
Sasuke might initially be a bit aloof but secretly be happy for them. He's always had a complex relationship with Naruto and Sakura, and deep down, he would see that they are good for each other.
Some in the ninja world would likely be shocked at first. The idea of Naruto and Sasuke having a son together goes against the traditional views of many. But those who are close to them, like their friends from Team 7, would probably be supportive. Kakashi, for example, might see it as a new step in the evolution of the ninja world's relationships. However, there would also be those who oppose it, especially from more conservative clans who might fear the implications of such an unorthodox union on their power structures.
They could go on a journey to find a way to heal any negative effects of the Sharingan on Sasuke. Naruto would be by his side every step of the way, providing emotional support. As they travel, they face various challenges, and Sasuke uses his Sharingan to analyze the situation while Naruto uses his brute strength. Their combined efforts make them an unbeatable team.
When Naruto's friends see him with the Spartan armor, it would cause a stir. They would all gather around, asking questions. Some would be excited about the new possibilities it presented, while others might be worried about where it came from and if it was dangerous. Naruto would have to explain what he knew about it, and they would all start brainstorming about how they could use it in their future battles or missions. They might also have to deal with any jealousy or envy that could arise if the armor seemed to give Naruto an unfair advantage.
