There's a fanfiction where Naruto is given a doujutsu by an ancient sage. This doujutsu gives him the ability to see the chakra flow in extreme detail. As a result, he can predict his opponents' moves more accurately and even disrupt their chakra systems with precision strikes. It makes for some really intense battle scenes.
One fanfiction could be 'Naruto: The Doujutsu Master'. In this, Naruto might inherit a powerful doujutsu through some unique plot twist, like a long - lost bloodline connection. He then has to learn to control it while still using his regular ninja skills.
In a certain fanfiction, Naruto's doujutsu is related to time manipulation. He can slow down or speed up time within his field of vision. This power completely changes the dynamics of his battles. He uses it not only in combat but also to save his friends from dangerous situations that would otherwise be impossible to avoid.
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 major theme is the exploration of the origin of the doujutsu. Is it something that was always within Naruto but just dormant? Or is it a gift from a mysterious source? Also, the theme of using the doujutsu for the greater good of the village is quite common. Naruto, being the selfless hero he is, would try to use this new power to protect Konoha from threats, both internal and external. In some fanfictions, the doujutsu also has a connection to Naruto's family history, which adds an element of mystery and intrigue to the story. This connection might lead to revelations about his parents or other relatives that he didn't know before.
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.
Well, I'm not sure of the exact titles of all 'Naruto has a doujutsu' fanfictions, but you can start your search on fanfiction websites. Look for tags like 'Naruto', 'doujutsu'. You might find some real gems. One possible plot in these fanfictions could be that Naruto's doujutsu gives him the ability to see through illusions more easily. This could have a huge impact on his fights against opponents like Itachi or Obito, who are known for their powerful genjutsu.
One interesting fanfiction could be where Naruto gets the Rinnegan and uses it to bring a new era of peace in the ninja world. He might use its powers to understand the true nature of chakra better and teach others. Another could be a story where Naruto has the Rinnegan and teams up with Sasuke in a whole new way, combining their powers in unexpected and powerful combinations.
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.
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.
A typical aspect is the training montages. Since he has a powerful bloodline, there are often scenes where Naruto has to train hard to fully master the powers it bestows. Also, his bloodline powers usually play a crucial role in battles, allowing him to defeat stronger opponents or turn the tide of a fight. For instance, he might use a bloodline - based jutsu to counter an enemy's ultimate attack.
One interesting fanfiction could be 'Naruto: The Wood Style Prodigy'. In this, Naruto discovers he has an affinity for Wood Style early on and has to hide it from the village at first. Another is 'Wood Style Naruto: A New Path' where he learns Wood Style from an ancient scroll and uses it to revolutionize the way ninjas fight in the Hidden Leaf. There's also 'Naruto's Wood Style Adventure' which focuses on Naruto using Wood Style to explore uncharted regions of the ninja world.
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.
