What are some possible themes in a 'naruto is an old man fanfiction'?

Maybe in the fanfiction, there's a new enemy that targets the old - timers like Naruto and Yamato because of their past achievements. They are forced to come out of retirement and use their rusty but still formidable skills to defend themselves and the village. They might also have to train some inexperienced shinobi along the way to help in the fight.

One common theme is the passing of the torch. Since Naruto is old, he often imparts his knowledge and skills to the younger generation.

One possible plotline could be Naruto using his knowledge from the future to prevent certain tragedies. For example, he might stop the death of a beloved character like Jiraiya.

One common theme is the passing of the torch. Since the old man Naruto is godlike, he has a lot to teach the younger generation. Another theme is redemption. Maybe Naruto has made some mistakes in his life and in his old age, he tries to make up for them with his newfound power.

One possible theme could be the fear of the unknown. Since we don't know much about this toe, it could represent something mysterious and scary that the old man has to deal with.

Perhaps the story could focus on Old Man Naruto's relationship with Yamhoto. They could be reminiscing about their adventures together. Yamhoto might be facing some sort of trouble, and Naruto, despite his old age, decides to help him out, showing his loyalty and friendship.

One possible theme could be the deconstruction of the hero archetype. Since it's about Naruto not being a hero, it might explore what it really means to be a hero and how Naruto fails to meet those criteria.

A common theme might be the exploration of taboos. Since having sex with an old man might be considered outside the norm in many cultures, stories could be using this as a way to break boundaries and shock the reader. Another theme could be the search for wisdom or experience. The old man is often seen as having more life experience, and in the context of a sexual relationship in the story, it could be about a younger person seeking something from the older one, like knowledge or a different kind of connection.

One possible theme could be wisdom. Old men in Chinese stories are often depicted as wise figures, passing on their knowledge and life experiences.

As I don't know the story, it could potentially have themes like wisdom since it involves an old man. Old characters in stories often carry wisdom.
