Naruto himself is often a central character. He might be exploring the secrets of Naruto Mountain or having some kind of adventure there. Sasuke could also be there, perhaps on a mission related to the mountain. Sakura might be involved too, using her medical skills to help those in need during an event on the mountain.
One interesting story could be about a hidden training ground discovered on Naruto Mountain. There, a young ninja finds a scroll with ancient techniques that were long forgotten. This discovery sets off a chain of events where they have to protect the scroll from various villains who also get wind of its existence.
Well, it could be about Naruto having some sort of special connection with the old man of the mountain. Maybe he discovers some ancient power or knowledge related to it. For example, the old man of the mountain might teach Naruto a unique jutsu or give him a task that will change the course of the ninja world.
Naruto is the central character as per the title. The old man of the mountain is another key character. Additionally, Iruka sensei might be included. He has always been important to Naruto's development. In this fanfiction, he could be the one who tells Naruto some old tales about the old man of the mountain, which sparks Naruto's interest in the first place. And there could be new characters created specifically for this fanfiction that are related to the old man of the mountain's world, like some sort of guardians or servants of the old man.
In Naruto fanfics, the'mountain of corpses' could be a central plot device. It might be something that the main character has to witness or deal with. This could be a turning point in their journey, pushing them to seek greater power or change their view on the ninja world. It could also be related to some sort of ancient prophecy or curse that causes such mass destruction. Maybe the fanfic is set in an alternate universe where the normal rules of the Naruto world are distorted, and this'mountain of corpses' is a common sight in battles.
Sakura would be extremely distraught. She has always cared deeply for Naruto, and seeing him in such a dangerous situation would make her rush to his aid immediately. She might use her medical ninjutsu to heal him if he's injured. Kakashi, on the other hand, would be shocked but also proud that Naruto has the courage to face his inner demons in such a drastic way. He would try to understand Naruto's motives and help him get back on track.
In some cases, the Mountain might be paired with other powerful warriors from different regions in fanfiction. For example, a character from Essos who has a unique fighting style. This could lead to some epic battles and exchanges of combat techniques in the fanfiction.
It can create a very dark and somber mood. The sight of a mountain of corpses is likely to shock the characters and the readers. This can drive the plot forward as characters react to such a horror. For example, a character might be motivated to find the cause and seek revenge.
Alma, Ennis's wife, is another character that shows up often in fanfiction. Her role as the woman caught in the middle of Ennis's conflicted feelings for Jack gives her a unique place in the story, and fanfiction can explore her side of the story more fully.
