Naruto might initially be shocked and hurt. After all, being expelled by his own family is a huge blow. But being 'godlike', he could quickly turn that pain into determination. He might decide to prove his worth and show his family that they made a big mistake.
Well, one possible plot could be Naruto leaving Konoha and finding a new group of allies who are also outcasts. They then form a powerful team to prove themselves to Konoha.
Iruka Sensei is often one of the characters. He has always been like a father figure to Naruto to some extent. In these fanfictions, he may offer Naruto a place to stay and continue to train him. Another one could be Jiraiya. He might take Naruto under his wing more so than in the original story, seeing Naruto's potential and his difficult situation.
Another plot could be Naruto's journey of self - discovery. After being kicked out, he realizes his own worth independent of his family name. He may focus on developing his skills even more, like his ninjutsu and his ability to make connections with people. He might start to understand that family doesn't have to be blood - related.
One possible reason could be his unruly behavior. Naruto is known to be a bit of a troublemaker in the series, always pulling pranks. In fanfiction, this might be exaggerated, and the orphanage might not be able to handle it anymore. Another reason could be that he's suspected of being involved in something dangerous or illegal, even if he's innocent. For example, if there are strange incidents around the orphanage and Naruto is the easy target to blame because of his reputation.
One possible reason could be his prankster nature. Maybe he played one too many harmless but annoying pranks on the staff or other orphans, and they decided they'd had enough. Another reason might be the fear of the Nine - Tails within him. Even if the people in the orphanage didn't fully understand what it was, they could sense something dangerous about Naruto and wanted to distance themselves from him for safety reasons.
Xander could be a creator or an owner. Maybe he is the person behind a brand, a story, or a platform. And he kicked out fanfiction because he wants to protect his original creation from being overshadowed or misinterpreted by fan - made stories. It's also possible that Xander is a figure within a community who has a particular vision for the content that should be present, and fanfiction didn't fit into that vision.
Another possibility is that in the fanfiction, Spider - Man's identity was revealed in a way that put the entire Avengers team at risk. The Avengers might then decide to distance themselves from him to protect their own secrecy and safety. This could involve kicking him out of the group to avoid any further potential threats associated with his exposed identity.
It could also be related to external forces. Maybe an enemy of the family or the village plants false evidence that makes Naruto seem like a danger. Since he is 'godlike', the family might believe the false accusations more easily, fearing his power, and expel him. Also, there could be a power struggle within the family, and those in power see Naruto's 'godlike' nature as a threat to their authority and use some excuse to kick him out.
