Are there any interesting characters in the 'naruto is the horseman of death fanfiction' other than Naruto?

I'm not entirely sure as there could be many different interpretations in such a fanfiction. It might involve Naruto being somehow related to the concept of the Horseman of Death, perhaps having powers or a role similar to that in a unique and alternate Naruto - inspired storyline.

Kakashi could also be a main character. He has lost many people close to him, like his father, Obito, and Rin. Facing the death goddess, he could be in a moral dilemma. He might be tempted to use her power to change the past, but also realizes the consequences that could come with meddling with death. His internal struggle could be a central part of the fanfiction.

For Sasuke, if he had a relationship with a female Naruto, her death would be a huge blow. He might become more reclusive and angry, blaming himself or others for not being able to protect her. He could even go on a quest for vengeance against those he deems responsible.

Well, surely Hinata would be there. As Naruto's wife, she would support him in his role as Uzukage. Maybe Boruto and Himawari would also be involved, learning about their Uzumaki heritage from their father. And there could be some other Uzumaki clan members who have been in hiding and now come out to help Naruto lead the village.

Sakura could be one of the performers, showing off her medical ninjutsu skills in a unique and entertaining way. Sasuke might be a brooding figure who is part of a dangerous acrobatic act. And Kakashi could be Naruto's adviser, helping him run the circus behind the scenes.

One plot idea could be that Naruto, as the Headless Horseman, is on a quest to find his lost head which holds the key to his true power. Another could be that he is wrongly accused of being a villain because of his spooky appearance, and he has to prove his innocence to the Hidden Leaf Village.

There could be Sasuke. Since Sasuke is Naruto's rival and often involved in the same major story arcs, he might play an important role in this fanfiction. His sharingan abilities could interact with Naruto's newfound speed in some interesting ways, either as an ally or an obstacle depending on the plot.

Definitely. Besides Naruto, other characters from the original series could have new roles. For instance, Sasuke could be a sort of rebel within the empire, challenging Naruto's rule in some ways while also having his own reasons for doing so. And then there could be characters from other villages who interact with the Naruto empire in different ways, like trying to form alliances or plotting against it.

Yes, there might be. Since it's a fanfiction, new characters could be introduced. They could be unique in their abilities, like having a power that's a combination of different ninja techniques. Or perhaps there are characters who are trying to fix the shattered world, with strong leadership qualities.

One possible plot could be Percy being chosen as the Horseman of Death due to some ancient prophecy. He might have to travel to the Underworld more often and deal with the spirits there in a new way. Maybe he has to collect the souls of those who are supposed to die but are being held back by dark magic.
