One possible plotline could be Naruto's journey of self - discovery. Left behind, he might start to question his place in the team and in the war. He could then go on to train alone, finding new jutsu and becoming stronger in isolation. This would lead to a more powerful and self - reliant Naruto emerging, ready to rejoin the fight on his own terms.
Maybe Naruto, being left behind, stumbles upon a hidden place or an ancient power source. He has to figure out how to use this new power without his team's support. Along the way, he meets some unexpected allies who also have been overlooked or left behind. Together, they form a new kind of unit and return to the war with a different perspective and new strategies.
In a fanfic, if Naruto is left behind by his team, he might first feel a sense of abandonment. He could then use this as motivation to train harder on his own. For example, he might discover new jutsu or ways to improve his skills. He could also cross paths with other characters who help him grow in different ways, like an old hermit who teaches him some unique wisdom.
One possible plotline could be Naruto's struggle with self - worth. Since his family neglects him, he might constantly doubt his value. He could start to seek validation from other sources like his friends or mentors in the ninja academy. For example, he may pour all his energy into training to prove that he's worthy despite his family's lack of attention.
One possible plotline could be Naruto feeling a great sense of betrayal. He might go off on his own journey to become stronger in a different way than in the original story. Maybe he meets new allies who help him discover new powers or techniques.
Maybe in the fanfic, Naruto and Hinata work together to rebuild the village. They use their unique skills and influence. Naruto, with his leadership skills and powerful jutsu, and Hinata, with her Byakugan and knowledge of the Hyuga clan's techniques. Their teamwork could strengthen their bond even more. And also, they might encounter some old enemies who are trying to take advantage of the post - war confusion, and they have to fight side by side again.
One possible plotline could be exploring their shared heritage. Maybe they discover they are brothers early on and team up against the darker forces in the Naruto universe. They could use their combined powers to bring about a new era of peace in the shinobi world.
Well, it might be that Rias sees Naruto as a rival in terms of power or influence in a new setting. So, she uses her devilish powers to abuse Naruto. In the story, Naruto could start out confused and hurt but then draw on his ninja training and positive relationships back home to slowly turn the tables and make Rias see the error of her ways. Maybe he even teaches her about friendship and loyalty, which are concepts not as prominent in her world.
Maybe the story focuses on Naruto learning about leadership from Hashirama. Hashirama was the first Hokage and had great leadership skills. He could teach Naruto how to make tough decisions for the good of the village, how to inspire the people, and how to deal with political situations within and outside the village.
Well, it could start with Anko being given false information about Naruto. Let's say someone convinces her that Naruto is secretly working with an old enemy of Konoha. She then starts to spy on Naruto. As she does this, she uncovers some things that seem to confirm the false information, but in reality, they are just coincidences or set - ups. So, she feels she has no choice but to betray Naruto to protect the village. It could also be that Anko has her own ambitions that conflict with Naruto's goals for the village, and she sees betraying him as a way to achieve her own ends.
At first, he would be shocked and hurt. Naruto values his team highly. However, he has a strong will. So he would quickly turn his feelings into motivation. He could start exploring new places to gain more experience and knowledge. He might also try to understand why his team left him behind, and use that knowledge to better himself and his relationships with them.
One possible plotline could be Naruto growing up with his uncle and learning different jutsu from him. His uncle might have a unique style of teaching that helps Naruto develop his skills faster. Maybe his uncle also has some secrets about Naruto's family that he gradually reveals as Naruto gets older.
