Well, Naruto's power would be severely reduced. Kurama was a huge source of his chakra and strength. Without Kurama's power, Naruto would have to rely more on his own natural abilities and the skills he has learned over the years. He might become more like his early self, having to strategize and train harder to face strong opponents.
Naruto's power might progress in several ways. Firstly, Kurama's serious training could involve better chakra control. Naruto could learn to access Kurama's chakra more efficiently without losing himself to the fox's rage. For example, he might be able to create more powerful and refined Rasengan variations. Secondly, Kurama could teach Naruto some of the ancient fox - related jutsus that have been lost over time. This would give Naruto an edge in battles, making him a more formidable opponent.
After Kurama's death, Naruto faced new challenges. His chakra reserves were reduced, but he continued to guide and inspire the younger generation of ninjas. He also had to adapt his fighting strategies without Kurama's immense power.
Well, he might have enhanced physical strength. Since Kurama is involved, Naruto could potentially have better control over chakra, which would boost his combat abilities significantly. For example, his Rasengan could be more powerful and easier to form.
Well, Kurama might train Naruto by teaching him how to better control and access chakra. Since Kurama has a vast amount of chakra, it could show Naruto unique ways to harness and use it. For example, it could guide Naruto in creating more powerful and complex jutsu by using their combined chakra in a more efficient way.
Well, it would significantly boost his power. The Rinnegan is an extremely powerful dojutsu. Naruto already has his vast chakra reserves and Sage Mode. With the Rinnegan, he could gain new abilities like the Six Paths techniques. He might be able to manipulate gravity, use the Outer Path to revive the dead (though this has its own moral and plot implications in the fanfiction world). His combat capabilities would be off the charts, making him one of the most formidable characters in the fanfiction universe.
The Kurama Brothers could be entities that have a similar origin to Kurama. They might have been part of the same chakra - based creation in the Naruto universe. They could possess some of Kurama's traits like great power and a connection to the natural energy in the world. They are often depicted as having their own personalities, with one being more hot - headed and the other more calm and calculating. Their relationship with Naruto usually involves them using their powers and knowledge to help Naruto grow as a ninja and a person. They might also have their own goals and motives that are intertwined with Naruto's journey.
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.
I have no definite answer for you. The availability of a comic after a character's death like New Power Girl often hinges on fan demand, creative direction, and publisher decisions. You might want to check comic forums or official announcements for any updates.
