In Naruto fanfiction, one common power - up is related to new jutsu creation. For example, some fanfictions might have Naruto develop a jutsu that combines the power of all five chakra natures in a completely unique way. This could give him an edge over his enemies like never before. Another aspect could be the enhancement of his Sage Mode. Maybe he finds a way to make it more stable and powerful, allowing him to stay in the mode for a much longer time without any negative side effects. There are also fanfictions where Naruto gains the ability to control time, which is a completely new and overpowered concept that makes for really interesting stories.

The 'naruto pain into power fanfiction' could potentially rewrite Naruto's character arc in a unique way. It may show him in situations where he is pushed to his limits by pain, more so than in the original series. This extreme pain could lead to a more profound and perhaps unexpected transformation of his power. For example, he might discover a hidden power within himself that was only unlocked through experiencing a great deal of pain. This could also lead to new plot twists and interactions with characters like Sasuke or Kakashi, as they react to this new, more powerful Naruto who has emerged from his pain.
In certain fanfic concepts, Naruto could get the phoenix power during a near - death experience. His strong will to survive and protect his friends could attract the phoenix spirit.

Well, it could be that Naruto's strong will and his connection to all the other tailed beasts play a role. Since he has befriended the other tailed beasts, their combined energy or some sort of spiritual link might attract the power of the Juubi. For example, in some fanfic concepts, the tailed beasts' collective consciousness decides to merge their powers with Naruto, which includes the Juubi's power as the ultimate form of chakra.
In a fanfiction, Naruto having the power of the sun could potentially have a huge impact on the chakra system. Since the sun is such a powerful energy source, it might disrupt or enhance the existing chakra flow. He could develop new jutsu that are based on solar energy rather than just the normal chakra types. This could lead to a whole new set of skills and abilities that are unique to him, and it would force his opponents to completely re - evaluate their strategies when facing him.
His relationship with his sensei, like Kakashi, would also change. Kakashi would probably be more cautious and try to guide Naruto in using this power responsibly. Naruto's new power could also attract the attention of new characters, either those who want to use him for their own gain or those who want to help him master it. This would bring new dynamics to his relationships.
