The combined forces of the remaining ninja clans in Konoha could also pose a threat to evil Naruto. If they put aside their differences and work together, they could pool their resources, jutsu, and manpower to try and halt Naruto's rampage. Although Naruto is extremely powerful, the collective strength of the village's ninja clans could potentially be enough to subdue him.
One possible motive could be a sense of betrayal. Maybe Naruto felt constantly ostracized in Konoha despite his efforts to be accepted, and over time, that bitterness turned into pure hatred. For example, if he was always treated as an outcast by the villagers even after saving them multiple times, it could drive him to destroy the very place that never truly welcomed him.
One interesting aspect could be seeing how the characters in Konoha react to a darker version of Naruto. They might be shocked, scared or even try to find a way to 'save' him. It could also show a different side of the Konoha community's values and how they handle such a drastic change in a well - known character.
Konoha's perspective may shift from trust to suspicion. They might start to question all of Naruto's actions, even the ones that were previously seen as heroic. It's like a crack in the foundation of their relationship with Naruto.
Konoha would initially be in shock. Naruto is a hero to many in the village, and his sudden departure with Itachi, who was once considered a traitor, would cause a lot of unrest. The villagers might start to question the leadership of the village, wondering why Naruto left and if there was something they could have done to prevent it.
Well, in some fanfictions, Naruto might outsmart Konoha by using his unique knowledge of the village's secrets that others don't know. For example, he could use his understanding of the old tunnels under Konoha to his advantage in a situation where he needs to escape or gain an upper hand in a conflict.
Ruby's speed and scythe - wielding skills could be very useful in Konoha. Her semblance of super speed would make her a formidable opponent in combat. She could quickly dodge ninja attacks and surprise her enemies. Her scythe could be seen as a unique and powerful weapon in the ninja world. Weiss's glyphs and ice magic would also be a great asset. She could use her ice to create barriers or freeze enemies in place, which is similar to some water - style jutsu. Her summoning of the Arma Gigas could be a new and powerful addition to the battles in Konoha.
One possible reason could be that Naruto feels betrayed by Konoha. Maybe he discovers some dark secrets about the village that make him lose faith in it. For example, if he finds out that the village elders were involved in unethical experiments or plots against his friends or family, he might not want to help.
They could bring new ideas. For example, if they come from a different place, their cultural ideas might influence Konoha's fashion or food. Their presence might also inspire the local kids to work harder in their ninja training, seeing two new and exciting role models.
It would be a huge blow to Konoha. Naruto is a hero in the village, and his departure would leave a big leadership void. The villagers would also lose a great source of inspiration. Hinata is from a respected clan, and her leaving would also have an impact on the clan's standing in the village. Morale among the ninjas might drop as they see two important figures leave.
