Perhaps they start off as enemies, not knowing their relation. But as the story unfolds, through various battles and interactions, they begin to suspect that there is more to their connection. It could be that they both have a strange mark on their body that is only found in their family, which leads them to uncover their relation. And then they have to decide whether to continue as enemies or join forces.
On a more emotional level, it could mean a lot to Naruto and Konan themselves. Naruto, who has always been searching for family, would gain a new family member. And Konan, who has lost so much, might find a new purpose or connection through this relation. It could lead to some really interesting character development for both of them.
In some fanfictions, there could be a situation where Naruto is affected by a powerful genjutsu that no one else can break. Konan, with her unique skills and perhaps some knowledge about the caster of the genjutsu, manages to save Naruto. It could be that she has to go through a series of trials or battles to get to the source of the genjutsu and free Naruto. This could also lead to a deeper connection between Naruto and Konan as they work together to find out who is behind the genjutsu and prevent further attacks.
One possible plotline could be Naruto's struggle to keep up in his ninja training due to malnourishment. His body might not be as strong as his peers', so he has to find ways to overcome this, like secretly foraging for food or relying on the kindness of some villagers who see his plight. Another could be that his malnourishment is a result of being ostracized, and as he tries to improve his situation, he also starts to question the village's treatment of him.
In a plotline, Naruto could be caught in a natural disaster that occurs near Kumo. The Kumo shinobi, with their strong sense of honor and duty, rescue Naruto. Once rescued, Naruto could learn some unique Kumo - style jutsu or training methods while he is there, which he later brings back to Konoha to improve his own skills and share with his comrades.
One possible plotline could be Naruto growing up on his own, learning survival skills at a very young age. He might become more cynical towards the idea of family. Another could be that he meets someone who becomes like a surrogate family, and through this relationship, he starts to heal his inner wounds. He could also start to search for the reasons why his family abandoned him, leading to a journey of self - discovery.
One possible plotline could be that Team 7 is influenced by an outside force, like a powerful enemy who has a way to manipulate their minds. They start to believe false information about Naruto that makes them turn against him. For example, they might be made to think Naruto is secretly working for their arch - enemies. Another plotline could be jealousy within the team. Maybe Sasuke gets jealous of Naruto's growing power and influence in the village and decides to frame him for something, causing the rest of the team to turn their backs on Naruto.
One possible plotline could be that Naruto is caught in a powerful enemy's fire - based jutsu during a battle. Maybe the enemy has some vendetta against him and wants to see him suffer. Another could be that Naruto sacrifices himself by jumping into a burning building to save civilians. He might then struggle to survive the intense heat and his injuries.
In a Naruto betrayed by friends fanfiction, a plot might involve Naruto's friends believing he's been corrupted by a new and powerful jutsu he's developed. They think it's changing him for the worse and decide to take action against him. This could lead to a big confrontation where Naruto is heartbroken at their lack of trust. Also, it could be that a secret from Naruto's past is revealed, and his friends, feeling deceived, betray him without really understanding the whole situation.
A possible plotline is that Naruto is killed by a powerful curse placed on him as a child. Maybe it was a curse from a long - forgotten enemy of the Uzumaki clan. His death would cause a chain reaction. Hinata might be so heartbroken that she devotes her life to finding a way to bring him back. Sasuke, on the other hand, could go on a dark path of revenge, believing that Konoha didn't do enough to protect Naruto. And Kakashi would be filled with guilt for not being able to safeguard his student.
One possible plotline could be that Naruto is targeted by a powerful new enemy in the village who is secretly working for an outside force. This enemy manages to catch Naruto off - guard and beats him up to send a message to the Hokage. Another plotline might involve Naruto being framed for a crime he didn't commit, and as a result, some of the villagers turn on him and he gets beaten up in the chaos. Or perhaps in a sparring match gone wrong with a much stronger opponent who doesn't hold back enough, Naruto ends up getting beaten up badly.
