Naruto would probably be really angry at first. He's a free - spirited person who doesn't like being forced into things. So he'd likely try to fight back right away, yelling at Sasuke about what he's doing.
The ninja community's reaction would be quite mixed. Some, like Naruto's close friends such as Shikamaru and Kakashi, would be supportive. They would likely offer their protection and assistance to Naruto during his pregnancy. However, there would also be those who are more traditional and might view Naruto's pregnancy as a weakness or something that goes against the norms of the ninja world. They could try to isolate Naruto or even oppose Sasuke's relationship with him because of it.
On the other hand, Sasuke could be worried. He may think that Naruto is in some kind of trouble or danger. Given their history and the care they have for each other in the SasuNaru dynamic, Sasuke's concern could lead him to be more protective. He might start investigating the situation on his own to figure out why Naruto is hiding his face and ensure his safety.
Sasuke might also be angry. Angry at the situation, angry at whoever or whatever caused Naruto's amnesia. His anger could fuel his determination to find a cure. He would push himself and Naruto harder in training, hoping that it would jog Naruto's memory, all while trying to hide his true feelings of worry and fear for Naruto's well - being.
He could feel a sense of guilt. Sasuke might think that his actions or their relationship issues pushed Naruto to leave. He may then set out to find Naruto, not only to bring him back but also to resolve their long - standing issues. For example, if there were unspoken words or unresolved fights between them, Sasuke would see this as an opportunity to set things right.
If Naruto were trained by the Hokages in fanfiction, it would be a game - changer. First, his chakra control would improve significantly as they are all masters in that aspect.

People would see him as not just a strong ninja, but one with the blessings and teachings of the greatest Hokages. This would also have an impact on his relationships. His friends might look at him in a different light, with a mix of awe and pride.
