He would have to struggle to keep his good nature while having these new, potentially dangerous powers.

One possible plot twist could be that Naruto, after learning more about Itachi's sacrifices for the village, starts to idolize him in a way that changes his own ninja path.

Maybe in this fanfiction, Naruto is exposed to a powerful dark jutsu that slowly corrupts his mind. As he becomes insane, he begins to abandon the values he once held dear.

In this fanfiction, a possible plot twist is that Naruto's transformation into a Jashinist causes a rift in the ninja world. Some villages see him as a threat and form alliances against him.

In the fanfiction, Percy might be chosen by some divine force to become an angel. As an angel, he may have to face the challenges of living in the celestial realm while still having ties to the mortal world.

Well, perhaps Percy discovers that he has some hidden angelic heritage all along. But due to some misdeed or a curse, he becomes a fallen angel. His friends from the Percy Jackson world might not recognize him or might be afraid of him at first. He has to prove that he's still the same Percy on the inside while dealing with new angel - like powers that he doesn't fully understand. He could also be on a quest to redeem himself in the eyes of the angelic realm, which would involve facing powerful angelic enemies and solving ancient angelic mysteries. This would be a great way to blend the two different mythologies of Percy Jackson and the concept of fallen angels.
