A third storyline might revolve around Naruto's older age making him a symbol of hope for an aging Konoha. As the village ages, it may face new challenges like a declining population of ninja. Naruto, with his experience and continued strength, could inspire a new wave of recruitment and training, ensuring Konoha's future as a strong ninja village.
One possible storyline is that Naruto uses his age - related wisdom to prevent conflicts that were previously inevitable in Konoha. For instance, he might foresee political unrest and take steps to stop it before it starts.
Another storyline could be that Naruto, being older, has traveled more extensively outside of Konoha. So, he brings back new techniques and knowledge, which he then uses to improve Konoha's defenses or its standing among other ninja villages. This could involve him training a new generation of ninja in these foreign - inspired skills.
Perhaps in this fanfiction, there is a dark prophecy that Naruto misinterprets as Konoha being the source of all evil in the ninja world. So, in his attempt to 'save' the world, he decides to destroy Konoha. Also, it could be that an evil entity has merged with Naruto, and the combined power has a grudge against Konoha for some past event.
One possible storyline could be that they leave Konoha in search of a new way to train. Maybe they've grown tired of the traditional methods in Konoha and believe they can learn more outside. They could encounter new ninja clans with unique abilities that they can incorporate into their own skills.
Often, if Naruto is older in fanfiction, he may take on different leadership roles within Konoha. Maybe he's already part of the decision - making council or something similar. His age could also mean he has a deeper understanding of the village's history and secrets, which could play out in various plotlines. He could be mentoring the younger generation in a more hands - on way, passing on his unique experiences.
One possible storyline could be Naruto getting new and unique powers from the fanfiction elements. For example, if the fanfiction has a concept of time - traveling powers, Naruto might use it to go back in time and change certain events in the Naruto universe, like preventing some of the major tragedies that happened in his past.
A possible storyline is that Naruto is framed for a crime he didn't commit in Konoha. Despite his efforts to prove his innocence, the village turns against him. This betrayal makes him lose faith in Konoha. He then decides to leave and start a new life elsewhere. As he leaves, he vows to find a way to expose the real culprits and make Konoha realize their mistake. He travels to different lands, learning new skills and making new allies who help him in his quest for justice against Konoha.
Naruto might forgive Konoha because he realizes that holding a grudge won't solve anything. He has seen the destruction that hatred can cause, like during the Pain arc. So, he chooses to forgive in order to move forward and bring about positive change. Another reason could be his respect for the previous Hokages and their ideals for Konoha.
One possible storyline could be that Naruto, feeling constantly neglected, decides to leave Konoha in search of a place where he can be truly accepted. He might stumble upon a hidden village that has its own unique ninja culture and there he begins to train in new and different ways, far from the scorn he faced in Konoha.
One possible storyline could be that his older sister was sent away on a secret mission when Naruto was young. Years later, she returns, having gained great power and knowledge. She then helps Naruto in his journey to become Hokage, teaching him advanced jutsu and giving him emotional support during tough times.
One possible reason could be that Naruto discovers some dark secrets about the village leadership that go against his values. For example, if he finds out that they have been using underhanded means to maintain power.
Another reason might be that Naruto is seeking a greater purpose. In the fanfiction, his 'godlike' state could make him realize that there are threats out there that he can't face while being tied to Konoha. He may leave to protect the world on a larger scale, believing that he can be more effective away from the village.
