Well, if Kami gives Naruto a bloodline in fanfiction, it could completely transform his abilities. He might gain powers that are way more unique and powerful than his normal jutsu. For example, he could have some sort of elemental bloodline that allows him to control a new type of energy. This would make him even more of a force to be reckoned with in battles against tough opponents like Sasuke or the Akatsuki members.
Well, if Naruto were to obtain a bloodline from Kami in a fanfic, it would be a huge game - changer. His physical and mental capabilities could skyrocket. He could have new jutsu that are on a whole different level, perhaps being able to heal at an accelerated rate or even have some sort of spiritual connection that allows him to foresee events. It would also likely cause a stir among the other ninja, who would either be in awe or fear of his newfound powers.
Maybe a magical amulet. This amulet could have special powers like protecting Naruto from genjutsu or enhancing his chakra control. Since Kami is a powerful entity in the Naruto universe, it makes sense for the gift to have some kind of extraordinary ability.
The symbiote might also have an impact on Naruto's personality. Since symbiotes often have their own sort of consciousness, it could lead to some internal conflict within Naruto. He might have to struggle to keep his own values while dealing with the symbiote's influence. On the other hand, if he can master it, he could gain a new level of confidence. Maybe it would give him an edge in his battles against stronger opponents like Sasuke or the Akatsuki members.
One possible plot could be that Naruto's new doujutsu gives him the ability to see the chakra flow in a more detailed way. This would enhance his combat skills as he could predict his opponents' moves better. He might also use it to understand the nature of different jutsus more clearly.
Sasuke could also be a great main character for this kind of fanfiction. With his already complex character arc in the original series, adding the kami bloodline to his story could take it in new and exciting directions. He could struggle with the power of the bloodline, perhaps fearing it would make him too much like those he has fought against in the past, or he could use it to seek revenge in a more powerful way than before.
One possibility is a space - time bloodline. This would allow Naruto to teleport or manipulate space in some way, similar to how Minato could use the Flying Thunder God Technique, but perhaps with more unique applications. It would give him a huge advantage in combat, being able to surprise his enemies and quickly get out of dangerous situations.
A story could revolve around a conflict between different clans due to the discovery of the kami bloodline. Some clans might see it as a threat to their power, while others might want to ally with the bearer of this bloodline. This would set off a chain of events including battles, political intrigue, and the forging of new alliances within the Naruto world.
His relationship with the older generations like Kakashi and Tsunade could shift. They would see Naruto as a more mature and capable ninja. Naruto could use the insights from his doujutsu to contribute more to the decision - making in the village, and they would respect his opinions more.
If the gift is a powerful weapon, it could give Naruto an edge in battles. For example, if it's a sword that can cut through any defense, he can face stronger opponents more easily, thus changing the course of his battles and his overall journey.
