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.
Well, considering the title, there might be a lead shinobi character who is highly skilled and brave. Maybe there are also some supporting characters like a wise old shinobi mentor or a young apprentice. And since it's set on the high seas, there could be some non - shinobi characters as well, such as a ship captain or a mermaid who interacts with the shinobi in different ways.
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.
Obviously, Naruto is one of the main characters since it's about his retired life as a shinobi. Sakura could also be a main character, perhaps she still works as a medical ninja and has a different relationship with Naruto now that he's retired. Another could be Boruto, Naruto's son, as he would be affected by his father's retired status.
Obviously, Naruto is one of the main characters as it's about him being a shinobi god. His friends like Sasuke and Sakura are likely to be important as well. They might support Naruto in his new role or have their own story arcs related to Naruto's transformation.
Sometimes, characters like Kakashi could also take on a different role in these fanfics. He might be faced with moral dilemmas that are far more complex than in the original series due to the darker nature of the story. And there could be antagonist characters that are original to the fanfic, like a powerful and evil shinobi leader who is trying to reshape the ninja world according to his dark vision.
Most likely Naruto himself could be one of the main characters as he has always been associated with the idea of peace in the Naruto series. He might be leading the efforts to bring about a more peaceful ninja world.
Obviously Naruto would be one of the main characters as the title implies he's the 'god of shinobi'. Sasuke could also be a main character as he has a long - standing relationship with Naruto in the original Naruto story. Sakura might be in it too, since she was part of Team 7 with Naruto and Sasuke.
There could be some original characters as main characters too. For instance, a young shinobi from a small, unknown village who rises to prominence during the Third Shinobi War. This character could bring a fresh perspective and unique abilities to the story, interacting with the well - known Naruto characters and changing the course of the war in the fanfic.
In this type of fanfic, the main characters usually include those that are iconic in their respective universes. For Naruto, it could be the main protagonists like Naruto Uzumaki, who is known for his never - give - up attitude and powerful ninjutsu. For the Percy Jackson side, Percy is a likely candidate with his ability to control water and his heroic nature. The 'unpredictable shinobi' might be a new character created specifically for this fanfic, or it could be an existing Naruto character with some new and unexpected traits added to them due to the crossover. They would interact with other main characters from both worlds, leading to various adventures and conflicts.
I don't know for sure as I haven't read this fanfic. But it's likely to have characters from the Naruto universe. Maybe Naruto himself could be one of the main characters, or perhaps some new characters created by the author related to this 'ashikabi' concept.
