What kind of doujutsu could Kyuubi give Naruto in the fanfiction?

In 'naruto kyuubi doujutsu fanfiction', a cool concept is the potential for new jutsu creation. Since the Kyuubi is a powerful entity, the doujutsu could enable Naruto (assuming he has it) to combine his regular ninjutsu with the Kyuubi's power in novel ways. Maybe he could create a fire - based jutsu that has the added effect of draining the opponent's chakra, as the Kyuubi is known for its voracious chakra appetite. Also, the doujutsu might have a special mode for communication with other tailed beasts.

It could be a doujutsu that allows him to see the future in fragments. So he can get glimpses of his opponents' next moves or potential threats in the near future.

One interesting concept could be the power dynamics between Naruto and the Kyuubi in relation to doujutsu. Maybe Naruto gains a unique doujutsu ability because of his connection with the Kyuubi. For example, he could have a doujutsu that allows him to better control the Kyuubi's chakra or even see the memories of the Kyuubi's past hosts.

One possible power is the ability to see through illusions more easily. Since the Kyuubi is a powerful entity, a doujutsu from it could give Naruto an edge against genjutsu users. It could break through complex illusions that would otherwise trap him.

Naruto is usually a main character as he has a connection with the Kyuubi. Since he already has the Kyuubi sealed within him, it's logical that he would be the one to potentially unlock or develop the Kyuubi doujutsu. Sasuke might also be involved. His rivalry with Naruto could lead to interesting interactions in relation to the doujutsu, either trying to obtain it for himself or learning to counter it.

There could be original characters as well. In fanfiction, authors often create new characters to add to the story. For example, a new ninja from a hidden village who has a special doujutsu that somehow connects with the Kyuubi's power. This character could become an ally or an enemy to Naruto. They could bring in new plot elements, such as a new form of chakra that is only accessible through the combination of their doujutsu and the Kyuubi's power, which would make for a very exciting and unique story.

It could be in an alternate universe fanfic where the rules of the Naruto world are completely rewritten and Naruto's identity as the kyuubi is central to a new and unique storyline.

One possible doujutsu could be a time - manipulating doujutsu. It allows the user to slow down or speed up time in a small area, giving them an edge in battles. Another could be a soul - reading doujutsu, which enables the user to see the true intentions and past experiences of others by looking into their souls.

Another might be the Byakugan. It gives a wide - range view and can see the chakra points in the body. In fanfiction, new and unique abilities of these doujutsu can be explored. For example, the author might create a situation where the Sharingan can not only copy physical techniques but also mental jutsus.

One possibility is that Naruto's new doujutsu gives him the ability to see chakra in a whole new way. He could use this to detect hidden enemies or weaknesses in his opponents' jutsu. For example, he might be able to see the flow of chakra in a genjutsu and easily break it.
