What are some doujutsu in the 'naruto has a rare doujutsu' fanfiction?

In the fanfiction, it could be that Naruto inherits the doujutsu. There might be a hidden lineage that Naruto is a part of, and when the time is right, the doujutsu awakens within him. This could be related to his Uzumaki heritage, which has many secrets yet to be fully explored. It's possible that some long - lost relative had this doujutsu and it has been passed down through the generations, finally emerging in Naruto.

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.

The doujutsu can drive the plot by giving characters unique powers. For example, if a character has a powerful doujutsu, it can make them a target for other characters who want to either steal the power or use it for their own purposes.

Well, in some fanfics, he might obtain them through some ancient ninja magic. Maybe he discovers a hidden scroll or a long - lost temple that grants him the power of all doujutsu.

Another possibility is that Naruto discovers some ancient and long - forgotten ninja art that allows him to either mimic or directly acquire the three doujutsu. It could be hidden in a secret scroll or a lost temple that he stumbles upon during one of his adventures. And this art gives him the ability to have all three doujutsu.

Well, if Naruto has all doujutsu in fanfiction, it means he has access to a whole new set of powers. For example, the Rinnegan's various abilities such as the Six Paths powers. This could lead to some really interesting plot developments, like him being able to use these doujutsu to bring peace to the ninja world in a different way than in the original story. Maybe he could use the Sharingan's genjutsu capabilities to defeat enemies without having to use brute force all the time.

There's also a fanfiction where Sakura's doujutsu is related to seeing the true nature of chakra. In this story, she can detect hidden threats and weaknesses in her allies and enemies alike. It adds a whole new dimension to her character.

The doujutsu from kami might also grant Naruto new offensive capabilities. It could potentially allow him to use some sort of energy projection or manipulation that is unique to this doujutsu. For example, he could fire beams of spiritual energy that can disrupt an opponent's chakra system.

They might obtain new doujutsu powers through genetic experiments. In some fanfictions, evil scientists or rogue ninja might try to combine different bloodlines to create a new and powerful doujutsu. Another way is through a divine encounter. For example, a character could be blessed by a god - like entity in the Naruto universe and be given a new doujutsu power.

One idea could be that the new doujutsu is related to time. Naruto can then see events from the past and future. This would be a huge advantage. He could learn from the mistakes of his predecessors, like Hashirama and Tobirama. Also, he could foresee the plans of his enemies and be better prepared for battles. He might see that Orochimaru is planning a new experiment in the future and stop it before it starts.
