If Naruto were the one to leave, it could potentially open up storylines focused on his self-discovery and growth away from his familiar surroundings. It could also impact the balance of power within the series' universe in unexpected ways.
In such a fanfiction, it could lead to a completely different power dynamic within the ninja village. Maybe Naruto's absence would give rise to new challenges and characters stepping up.
If Naruto had left, it might have caused chaos in the village. His absence could have given rise to new villains or changed the relationships among the remaining characters. Also, his journey outside could have introduced him to unexpected allies and challenges.
If Sasuke never left, the story would have taken a completely different turn. The dynamics between Naruto and Sasuke would have been much more straightforward, and their growth might have been along a different path.
Well, Naruto has a very warm and persistent personality. He's always there for his friends, and he has a big heart. In fanfiction, Sakura might see these qualities in Naruto and realize his true value. He's the kind of person who can make her laugh and feel safe, which could be very appealing compared to Sasuke's more brooding nature.
It could be a powerful enemy like Orochimaru. Orochimaru was always interested in Sasuke's potential, but if the plot changes and Naruto gets bitten, Orochimaru might see Naruto as an equally interesting subject to experiment on.
Kakashi might also side with Naruto in this scenario. He has trained Naruto and has a deep bond with him. If Kakashi discovers that Naruto has been wronged, he could choose to follow Naruto rather than the village's orders. Additionally, Hinata might be an ally. Her love for Naruto could make her stand by his side, believing in his good nature no matter what the village says.
In the 'naruto is protected by sasuke fanfiction', Sasuke's protection of Naruto could be multi - faceted. Sasuke, being a powerful ninja, would first of all use his physical strength and speed to block attacks aimed at Naruto. Emotionally, his bond with Naruto would make him extremely vigilant. He might sense Naruto's distress from afar and rush to his aid. In terms of strategy, Sasuke would likely plan their movements carefully when they are in dangerous situations, ensuring Naruto is always in a relatively safe position. His ability to quickly analyze a battle situation and react accordingly would be crucial in protecting Naruto.
Yes, there are such fanfictions in the Naruto fanfiction community. Some fans like to explore unique and creative scenarios in their writing, including this rather unexpected one.
I don't think it's a common type. The typical Naruto fanfictions usually revolve around things like the ninja battles, the growth of the characters, or the complex relationships in a more traditional sense. The concept of one character being the 'property' of another is a bit extreme and not in line with the general feel of the Naruto series. So, it's not likely to be a very common form of fanfiction.
In some fanfictions, Naruto might reject Sasuke because of Sasuke's continuous pursuit of power in a way that endangers others. Naruto, who values friendship and the safety of the village, could see this as a betrayal of their shared values.
It might be for Naruto's own good. Sasuke may believe that Naruto is on a dangerous path that will lead to his downfall. So he captures him to keep him from making bad decisions, like sacrificing himself for the village or something similar. He wants to save Naruto from himself in a sense.
