However, it might also attract unwanted attention. Other villains or even some of the shinobi villages could see Naruto with Kisame's sword and assume he has some sort of alliance with Kisame or the Akatsuki. This could lead to him being targeted or distrusted by others.
On a more personal level, Naruto might struggle to master the use of the sword. It's a different type of weapon compared to what he's used to, like his kunai and shuriken. He'll have to learn new techniques and how to integrate the sword into his fighting style, which could be a difficult and time - consuming process.
Iruka could be an important character. He's always been like a father figure to Naruto, and now with this new revelation, he might have to help Naruto deal with it. Hinata could also be in the story, and her feelings for Naruto could be complicated by his connection to Kisame. And then there could be some original characters created just for this fanfiction, like a ninja who was a former ally of Kisame and has some information for Naruto.
Well, in some fanfictions, Naruto might defeat Kisame in a battle and take the sword as a trophy. Maybe he uses his newfound Sage Mode powers or some other advanced jutsu to overpower Kisame and claim the sword.
One possible consequence could be that Naruto gains a new and powerful weapon. This sword might have unique abilities that could enhance his combat skills. He could use it to intimidate his enemies or as a last - resort weapon when his regular jutsu are ineffective.
In a fanfic of Kisame and Itachi taking Naruto, it might explore the relationship between the two Akatsuki members and Naruto. Itachi has his own complex reasons for his actions, and Kisame is his loyal partner. When they take Naruto, Itachi might be conflicted as he has a connection to Naruto through Sasuke. They could end up in a situation where they have to make a choice about what to do with Naruto.
When Naruto absorbs Zetsu in the fanfiction, it could impact his mental state as well. Zetsu has been involved in many dark and devious plans. Naruto might have to struggle with the knowledge and influence of those. However, on the positive side, Naruto could use Zetsu's ability to communicate with the plants and gather intelligence from the natural world. This would expand his range of information sources and give him an edge in strategic planning during battles.
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 possible consequence is that Naruto's body might not be able to handle Kurama's full power all at once. It could lead to physical harm or even death if not managed properly. Also, his relationships with Sakura, Sasuke and others would be in jeopardy as they might not recognize the Naruto under Kurama's control.
