One possible consequence could be that Naruto's body takes a huge toll. Since Kurama is such a powerful entity, summoning him might drain Naruto's chakra to a dangerous level, leaving him vulnerable after the summon. In some fanfictions, he might even pass out immediately after Kurama is summoned.
Another consequence could be the reaction of other characters. Some characters might be in awe of Naruto's ability to summon Kurama, while others might be afraid. This could lead to a change in how they interact with Naruto. Enemies might become more cautious, and allies might either be more trusting or start to fear Naruto's new - found power.
Well, Naruto's mental state could be affected. Since Kurama has a very strong will, Naruto might have to struggle more to keep his own personality intact while merged. On the other hand, it could also lead to a deeper understanding between them, which in turn could result in Naruto being able to access Kurama's memories and knowledge. This could give him an edge in battles as he might learn about ancient fighting techniques or secrets of the ninja world.
One possible consequence is that Naruto's body might not be able to handle Kurama's full power all at once. It could lead to physical harm or even death if not managed properly. Also, his relationships with Sakura, Sasuke and others would be in jeopardy as they might not recognize the Naruto under Kurama's control.
In fanfiction, it could also attract unwanted attention. If Naruto summons Rashomon in a public place or during a battle, it might draw the eyes of even more powerful enemies or villains who would then target him specifically because they see him as a threat with this newfound ability. For example, some secret organizations might see him as a potential tool or a danger to their plans and start to plot against him.
One consequence could be a change in Naruto's identity. He might have a different view of himself and his place in the ninja world. Another is that his relationship with the other characters, like Sasuke or Sakura, could be altered as they might view him differently. Also, his power origin might be more directly related to Kurama, and he could have access to different forms or abilities earlier.
One consequence is a change in his physical strength. Kurama provided Naruto with a huge boost in power, so without it, he might not be as strong in terms of brute force. However, this could also force him to become more strategic in combat.
One consequence could be a huge power boost. Naruto would become extremely strong, which might change the power balance in the fanfiction world. Enemies would be more cautious of him, and allies might rely on him more. Another consequence could be the internal struggle. The Kyuubi has its own will, so Naruto might have to constantly fight to maintain control when it's summoned.
One possible plotline could be that Naruto, due to some external influence or his own preoccupations, fails to communicate with Kurama as he used to. This might lead to Kurama feeling lonely and neglected. For example, if Naruto gets involved in a complex political situation in the village, he might focus all his attention on that and forget about the bond he has with Kurama.
Sure. In fanfiction, writers have the freedom to reimagine things. Naruto's Kurama is a powerful and iconic part of the Naruto series. If it were to be a Sacred Gear in a fan - made crossover story, it could bring a whole new dynamic. For example, it might interact differently with other characters or have different abilities in the context of the new setting.
In this 'fem kurama is possessive of naruto fanfiction', Fem Kurama might have some complex character traits. Her possessiveness could indicate that she is extremely loyal to Naruto. However, this loyalty can be misconstrued as over - possessiveness. She may be a bit controlling, thinking she knows what's best for Naruto. At the same time, she could be a very emotional character, with her possessiveness being a manifestation of her deep affection for Naruto. This could lead to her being impulsive at times, especially when she feels Naruto's safety or their relationship is being threatened.
It could also be due to a misunderstanding. Suppose Naruto accidentally does something that Kurama misinterprets as a threat to its own existence. For example, if Naruto tries a new jutsu that Kurama wrongly perceives as an attempt to suppress it further.
