I'm not sure specifically as it's a fanfiction and can vary greatly. But it could potentially have Naruto characters like Naruto himself or Sasuke, combined with some Tokyo Ghoul characters like Kaneki. Maybe there are also some original characters created for this fanfiction.
In 'naruto ghoul neglected fanfiction', there might be some interesting concepts regarding the power systems. Since it combines two different universes, the way powers interact could be fascinating. For example, how would a jutsu work when a character has ghoul - like abilities? Also, the social structures from both worlds might be blended in unique ways, creating new conflicts and relationships.
A story could revolve around a Naruto character who discovers a group of neglected ghoul - like beings in a hidden part of the ninja world. The character decides to help them integrate into society while facing opposition from those who are afraid of the unknown.
Set your story in a unique location within the Naruto universe that has been affected by the presence of ghouls. This could be a village on the outskirts that has to deal with neglected ghouls. You can explore how the local culture and ninja way interact with these strange beings, and how the characters grow in this complex environment.
Perhaps he's been influenced by someone who gives him bad advice. For example, if someone tells him that natural talent is enough and training is overrated. Also, he could be dealing with some personal problems, like a conflict within his family or among his friends that takes up all his time and mental energy, causing him to neglect training.
He might start to rely on his friends more. For example, Sasuke and Sakura could become his main source of emotional support. He would focus on training with them and sharing his feelings, which in turn helps him to grow stronger and more independent.
In Naruto, the Jinchuuriki were often treated poorly. In fanfiction, this neglect can be explored in many ways. One common approach is to focus on the emotional and psychological impact on the Jinchuuriki. For example, they might feel isolated from the rest of the village due to the fear and prejudice associated with the tailed beasts within them. This can lead to some really interesting character development stories in fanfiction.
In a fanfiction, perhaps neglected Naruto runs away from Konoha and ends up in the same area as Yugito. Yugito, having also faced her own share of hardships, takes Naruto under her wing. They bond over their experiences, and Yugito helps Naruto to better understand his chakra nature by sharing her knowledge of the tailed beasts' chakra. This could lead to Naruto developing new abilities and a newfound confidence.
One reason could be that some fanfiction authors might focus more on other aspects like new jutsu or character relationships outside of the Uchiha clan. They may not fully understand the potential of Sharingan, which has a wide range of abilities from basic perception enhancement to powerful genjutsu. Another factor could be the over - popularity of some other elements in the Naruto universe, like the tailed beasts, which overshadow the Sharingan in their stories.
It might be explored through lack of training or guidance. Since he's godlike, the village might think he doesn't need any help. So, they neglect his development in terms of combat strategies or new jutsu, leaving him to figure things out on his own.
