Well, in some fanfic concepts, Kurama might release Naruto's potential by sharing its own chakra in a more direct and unrestricted way. Maybe it could be like a full-on infusion of Kurama's power, which then unlocks hidden abilities within Naruto that were previously dormant due to Naruto's own self - imposed mental blocks or lack of proper training to handle such power.
One consequence could be that Naruto became extremely powerful all of a sudden. This newfound power might have made his enemies fear him more. For instance, the Akatsuki members who were after him might have had to re - evaluate their strategies.
Naruto would likely become more powerful. With the Yin Kurama, his combat abilities could increase significantly. He might also become more mature as he has to deal with the added responsibility of this new power. For example, he would need to be more cautious in using it so as not to harm others accidentally.
Another plotline might be that Kurama, having been with Naruto for so long, has some unfinished business related to the ninja world. He enlists Boruto's help to complete it. This could involve uncovering secrets from the past or righting some old wrongs. And along the way, Boruto would grow as a ninja and as a person.
One potential consequence could be that he faces discrimination from other ninja who are jealous or suspicious of his new - found power. Some might see him as a threat and try to undermine him.
Well, it could be about a high - tech world where Naruto has a mecha version of Kurama. Maybe the plot involves fighting new and powerful enemies that can only be defeated with the combined strength of Naruto and his mecha Kurama. The fanfic could also explore how Naruto bonds with this mechanical version of Kurama, different from his connection with the original Kurama.
For Naruto, it would be a whole new experience. He'd be constantly trying to communicate with the mecha Kurama, learning its quirks. Shikamaru might be the one thinking about the strategic uses of mecha Kurama in battle. He'd be coming up with plans on how to best utilize it. As for Kurama, he could be in an internal struggle. Part of him would want to stay relevant in Naruto's battles, while another part would be curious about this new mechanical version of himself and how it could help Naruto in the long run.
In fanfic, Kurama could improve Naruto's body by melding their life forces in a new way. This new connection might give Naruto enhanced senses. His eyesight could become sharper, allowing him to spot enemies from a greater distance. His hearing could be more acute, enabling him to detect stealthy movements. Moreover, this could also lead to an increase in Naruto's overall stamina, as Kurama's energy constantly revitalizes his body, making him able to endure long - drawn - out battles or intense training sessions.
Perhaps Kurama has some hidden ability that allows it to manipulate matter at a fundamental level. Using this ability, it could assemble atoms and molecules to construct a new body for Naruto. This process might be tied to the Kekkei Genkai in the fanfic, where the unique genetic trait plays a role in how the body is formed and stabilized.
Well, in some fanfics, the story might start with Naruto getting a premonition or some kind of sign that Kurama is suffering under the seal. So, he decides to free Kurama. He then embarks on a journey to find a way to break the seal. Along the way, he meets various characters from the Naruto universe who either help or hinder his progress. Once he finally frees Kurama, they team up to face a greater threat to the ninja world that neither could have faced alone.
