Well, there might be a mysterious soul that only Naruto can see. This soul could have some important information about a coming disaster. And also, the soul of a long - lost relative. Interacting with this relative's soul could give Naruto a new perspective on his family and his place in the ninja world. It could also help him develop his abilities further.
Well, it could make the plot more complex. For example, he might be able to see the souls of the enemies before they attack, thus getting an advantage in battles. He could also use this ability to communicate with the spirits of the dead ninjas and gain some unique knowledge or skills from them.
Naruto himself is always interesting. In fanfiction, he might have different personality traits or powers that make him even more engaging. His determination and never - give - up attitude always shine through.
Well, it could mean he has a very dark and powerful ability. Maybe it makes him feared by many in the fanfiction world. It might also change his relationships as others could be scared of him or try to use him for this power.
Sasuke, on the other hand, would be more calculating. He'd study the enemies' patterns carefully. In the Dark Souls setting, he'd likely focus on finding the most powerful weapons and armor. He might even try to master some of the Dark Souls - specific combat techniques. His Sharingan would give him an edge in quickly analyzing the situation, much like it does in the Naruto series when he faces tough opponents.
Well, it could make some characters view him as strange or special. His friends might be curious and a bit wary at first. For example, Sasuke might be initially skeptical but later come to rely on Naruto's unique ability in some situations. And Sakura could be both scared and intrigued, which would add new layers to their friendship dynamics.
Naruto's ability to see the dead would be a game - changer in his relationships. It would add a new layer of complexity. Some villagers who already had a negative view of him might use this as more fuel for their dislike. But his true friends would support him. Naruto could communicate with the dead shinobi and learn from their experiences. This new knowledge could be shared with his comrades, making him an even more valuable asset to the group and deepening their relationships.
If Naruto sees a future where he and Sakura are not as close as they are in the present, he might start to distance himself from her, thinking it's for the best. Or on the other hand, he could try to change the future by being more open and communicative with her. Also, with Sasuke, if he sees a future where Sasuke is in more danger than he thought, he would redouble his efforts to keep Sasuke safe and this would likely deepen their complex relationship.
Sasuke is often a common character. Since they have such a deep relationship in the original Naruto story, it's likely they'll interact in the alternate universe too. Kakashi could also be a common one. He was Naruto's teacher, so it makes sense for him to be around in different universes. And Sakura, as part of the original team, is also likely to interact with Naruto in these fanfictions.
Obviously Naruto himself would be a main character, in his dark form. There might also be other characters like Sasuke. Sasuke might be in a position of either trying to stop Naruto or joining him in his dark deeds. And Sakura could also be there, perhaps as a voice of reason trying to bring Naruto back from the darkness.
Well, Naruto's ability to see chakra can give him a huge advantage in combat. He can easily detect an opponent's chakra flow and predict their moves. For example, if an enemy is gathering a large amount of chakra in their hands for a powerful attack, Naruto can see it and dodge or counter - attack before the attack is launched. This allows him to be more proactive in battles instead of just reacting to his opponent's visible actions.
