In some fanfictions, one could be the Sharingan, which gives abilities like seeing chakra and predicting moves. Another might be the Byakugan, with its great vision powers. And the third could be something unique like the Ketsuryugan, which could have powers related to blood manipulation.
In many 'naruto has 3 bloodlines' fanfictions, the first bloodline could be the Uzumaki's strong life force and large chakra reserves, which is almost like a bloodline trait considering how unique it is among the ninja clans. Then, there's the Hyuga's Byakugan, with its ability to see the chakra network and almost 360 - degree vision. For the third bloodline, it could be a fictional one created by the author, like a bloodline that allows the user to manipulate time on a very small scale, which would add a really interesting dynamic to the Naruto universe.
In the 'naruto has 3 bloodlines' fanfiction, these bloodlines can have a profound impact on the story. For instance, if one of the bloodlines allows Naruto to communicate with animals in a special way, it could lead to new alliances and ways of gathering information. A bloodline that enhances his ninjutsu in a unique way might make him the target of other villages or rogue ninjas who want to steal his power. And a bloodline that gives him the ability to heal others more effectively could change his role within the village from just a fighter to also a healer, which would completely shift the relationships he has with other characters and the overall direction of the story.
The six bloodlines in the 'naruto has 6 bloodlines fanfiction' could be really diverse. It might start with the Senju bloodline which is known for its great chakra reserves and strong life force. Then there could be a bloodline related to some sort of space - time manipulation, like a new version of the Kamui ability. There might also be a bloodline that gives the user the ability to communicate with animals in a more profound way, similar to but different from the Inuzuka clan's bond with dogs. Since it's a fanfiction, the author has a lot of creative freedom to come up with these bloodlines.
Well, if Naruto has three bloodlines in fanfiction, it could greatly enhance his abilities from the start. For example, one bloodline might give him enhanced physical strength, another could provide unique ninjutsu capabilities, and the third might offer some sort of special perception. This would likely make him more confident earlier on as he wouldn't have to struggle as much with basic power levels. It could also lead to him being more isolated as others might fear or envy his multiple powers.
In some fanfictions, Naruto might be given the Uchiha bloodline, which could potentially grant him the Sharingan. Another common one is the Senju bloodline, as it was very powerful and associated with Hashirama Senju. Some might also give him the Hyuga bloodline for the Byakugan.
One interesting combination could be the Uchiha bloodline with the Uzumaki bloodline. The Sharingan from the Uchiha and the massive chakra reserves and sealing abilities of the Uzumaki could create a really powerful Naruto. Another could be the Hyuga bloodline combined with the Uzumaki. The Byakugan's visual prowess along with the Uzumaki's chakra would give Naruto enhanced perception and more chakra to use for powerful jutsu.
Maybe he uses some kind of special jutsu. It could be a new form of his shadow clone jutsu where the clones are able to analyze and then copy the bloodline traits of the opponents they encounter.
The new combinations of abilities from the six bloodlines make it interesting. It allows for unique character development and power - ups that we don't see in the original Naruto story.
For Naruto in fanfiction, the three bloodlines could be really interesting. He could have the Rinnegan as one bloodline, which would open up a world of powerful and unique abilities like the Six Paths techniques. Another could be the Ice Release bloodline from the Yuki clan, allowing him to control ice in various forms. And finally, the Magnet Release bloodline from the Sand village, which would let him manipulate magnetic forces. These bloodlines would completely change the way he fights and is perceived in the Naruto universe.
One interesting ability would be combining the Uchiha's fire - based jutsu from the Sharingan with the Uzumaki's chakra - enhancing abilities. This could create some really powerful and unique fire - type attacks. And with the Hyuga's Byakugan, he could precisely target weak points in an opponent's chakra system while using his own powerful chakra punches. He might also be able to use the Nara's shadow - binding techniques in a more enhanced way with his newfound power boost.
In this fanfiction, the Sharingan from the Uchiha clan is an obvious choice. It has so many abilities like the ability to copy jutsu and predict movements. Naruto could become even more of a prodigy if he absorbs it. Also, the Aburame clan's ability to control bugs could be quite interesting. Naruto could use bugs for reconnaissance or even in combat in ways that are different from his normal fighting style. And the Inuzuka clan's connection with animals, if Naruto could absorb that bloodline, he might be able to form a stronger bond with his summons or other animals in the wild.
