Well, in the fanfic, the revival might lead to new alliances and rivalries. Suppose Obito is revived. His past actions might make some people still distrust him, while others might see his revival as a chance for him to make amends. This could create new political and social dynamics. Also, the revived characters could bring back old secrets or knowledge that had been lost. This might be a good thing in some ways, like finding a new way to fight a common enemy, but it could also be dangerous if that knowledge falls into the wrong hands.
One potential consequence could be widespread destruction. The Kyuubi is an extremely powerful force. Buildings would likely be demolished, and many shinobi might be injured or killed trying to combat it. Another consequence could be a shift in the power dynamics within Konoha. Some might see Naruto as a threat, while others might try to use this situation to gain power themselves.
He could be feared by the remaining ninja. Since he has killed all his enemies, others might see him as a ruthless killer rather than a hero. This could lead to isolation as people would be scared to approach him.
One consequence could be that Naruto became extremely powerful all of a sudden. This newfound power might have made his enemies fear him more. For instance, the Akatsuki members who were after him might have had to re - evaluate their strategies.
One consequence could be that he faces opposition from some clan members who might not be ready to accept him as the leader right away. After all, taking over a clan is a big deal.
Well, Minato could be one of the characters. He was Naruto's father and died when Naruto was just a baby. Reviving him would allow Naruto to finally have a proper father - son relationship. Another possibility is Neji. His death was quite tragic during the war, and his revival could bring some interesting plot developments in the fanfic, especially in terms of his relationship with Hinata and the rest of the Konoha 11.
The most obvious consequence would be chaos. Naruto was the hope for the village. His death would likely lead to a great sense of despair among the villagers. Konoha might lose its strength and confidence.
One consequence could be that it makes him an outcast. Controlling the dead is often seen as a dark and forbidden art, so his friends and allies might be afraid of him or turn against him.
One potential consequence could be a loss of his sense of self. If he's raised just as a weapon, he might not develop his own values and emotions fully. He could become a tool for others' purposes without any real understanding of right and wrong. Also, his relationships would be severely affected. His friends might fear him or be used against him. And he may struggle with identity issues, constantly torn between being a weapon and a person with his own will.
There could be negative impacts on characters' bodies. The sudden change in gravity they experience might cause internal injuries. If a character is constantly exposed to abnormal gravity levels, it could affect their chakra flow and overall health, just like how extreme conditions in the real world can harm the human body.
One potential consequence could be that he faces discrimination from other ninja who are jealous or suspicious of his new - found power. Some might see him as a threat and try to undermine him.
