It could be about Naruto characters in a high - seas adventure setting. Maybe they're on a ship, facing pirates or other sea - related challenges, while still using their shinobi skills.
One interesting concept could be new and unique jutsu created by the god - level shinobi. For example, a jutsu that manipulates time in a different way than the existing ones in the Naruto universe. Another concept might be the relationships between these super - powerful shinobi and the normal characters. They could act as mentors, or their presence could change the power dynamics in the Hidden Villages.
Kakashi Hatake is another beloved character in Kage - level shinobi fanfiction. His experience and unique abilities can be further developed in stories. He could be in a position where he has to make tough decisions as a Kage - level figure. Tsunade is also a popular choice. Fanfictions can focus on her past experiences and how they shape her actions as a Kage - level shinobi, or her relationships with other powerful characters in the village.
Some fanfictions might explore the personal lives of Kage - level shinobi. For instance, a story about a Kage - level shinobi who is also a single parent trying to balance their duties towards the village and raising their child. Or it could be about the love life of a Kage - level shinobi, how they deal with relationships while being in such a high - profile and dangerous position in the ninja world.
Naruto himself is often a popular choice in these fanfictions. Since he already has a lot of growth potential in the original series, it's easy to take him to a god - level. Sasuke is also popular as he is Naruto's rival and has his own set of powerful abilities. Another popular character could be Madara Uchiha. Given his already strong powers and complex character, fanfiction writers like to take him to new heights in the god - level shinobi concept.
Since it's a Naruto - related fanfic set in the high seas, Naruto is bound to be a central figure. His determination and powerful jutsu would play a key role. However, other characters from the Naruto world would also be involved. For instance, Rock Lee could be there, showing off his unique taijutsu skills on the ship decks or against enemies in the water. And Hinata might be part of the story too, perhaps using her Byakugan to detect hidden threats in the vast ocean or on uncharted islands.
There is a fanfic called 'Beyond Kage'. In this one, the story goes beyond the typical understanding of kage - level power. It explores new abilities and challenges that kage - level shinobi might face, with a really engaging plot that keeps you hooked from start to finish.
Perhaps it's a shinobi who has retired after a long and eventful career. He could be someone who has seen the darker side of the shinobi world and wants to make sure Naruto doesn't go down the wrong path. He might have been a wandering shinobi who finally settles down with Naruto. For example, he could be a shinobi from a different village who has a unique set of skills to teach Naruto.
In a lot of fanfiction, Naruto becomes the God of Shinobi. This is often because the writers want to create a more fantastical version of the Naruto world. By making Naruto a god - like figure, they can introduce new elements such as different power hierarchies, new types of jutsu that are on a divine level, and unique relationships with other characters. It's a way to expand the already rich Naruto universe in a very different direction. For example, in some fanfictions, Naruto as the God of Shinobi has the power to reshape the world or even rewrite the laws of chakra. This not only gives the story a new and exciting plot but also allows for a deeper exploration of the concepts introduced in the original Naruto series.
