Well, for one, Naruto's perspective on life would change drastically. Since he's cursed with immortality, he'd start to question the value of things like honor and sacrifice in a different way. Maybe he'd become more jaded over time. And his relationships? They'd be so complicated. His friends might grow old and pass away, leaving him with only memories. And he'd have to deal with the fact that he can't die no matter how dangerous his battles get.
In such a fanfiction, Naruto might experience extreme loneliness. He would watch his friends and loved ones die while he remains alive. He could also be hunted or studied because of his immortality, constantly on the run from those who want to use his unique condition for their own gains.
His character could develop in a very complex way. At first, he'd probably be confused and scared about the curse. But as time passes, he might use his immortality for good in a more extreme way. For example, he could take on the most dangerous missions without fear of death. However, the constant cycle of seeing people he loves die would also harden him. He might become more calculating and less impulsive, as he realizes the long - term consequences of his actions. He could also gain a deeper understanding of life and death, and maybe try to find a way to break the curse not just for himself, but for others who might be suffering from similar fates.
Maybe Percy tries to break the curse. He could embark on a quest to find a powerful magical artifact or a long - forgotten spell that has the power to reverse his immortality. Along the way, he would face various challenges and meet interesting characters who either help or hinder his journey.
The origin of the cursed sword could be from an ancient and evil clan. Maybe they used dark magic to create it, and it was lost over time until Naruto discovers it by chance. For example, it could have been buried in a forgotten tomb that Naruto stumbles upon during a mission.
If Hogwarts could read the 'The Cursed Child' fanfiction, it would probably be a very strange experience. Since fanfiction often takes the story in different directions. Hogwarts, as an old and traditional magical place, might be quite confused by some of the wilder interpretations of the characters and events. For example, if a fanfiction had a completely different view of the relationship between Harry and his son, it could be like Hogwarts was seeing a distorted mirror of its own world.
The cursed sword could enhance Naruto's physical strength. Since Naruto already has a lot of raw power, the sword might multiply it, making his punches and kicks even more powerful. For example, if he punches an enemy while holding the sword, it could send the enemy flying farther than normal.
Percy would probably develop a greater sense of patience. Since he has all the time in the world, he could learn to wait for the right moment to act. This new - found patience could help him in his adventures and in his attempts to either break the curse or come to terms with his immortality. He might also study various things over the long years, becoming more knowledgeable and wise, which would also shape his character.
Well, in some 'naruto cursed fanfiction', there are stories that focus on the curse marks in a different way. Like, they might expand on how the curse marks could have affected the characters' mental states more severely. Some might also create new curses that are specific to certain clans that were not in the original story. These types of fanfictions can be quite interesting as they add a new layer of mystery and darkness to the Naruto universe.

Another theme could be related to the origin of the curse. It might be something passed down through generations in the Uzumaki clan, or perhaps a result of some forbidden jutsu. This could lead to Naruto having to uncover the mystery behind the curse to break it.
In the original Naruto story, Naruto doesn't have an overarching 'curse' in the traditional sense. Fanfiction with this concept adds a new layer of conflict. The original focuses more on Naruto's journey to become Hokage and gain acceptance, while the cursed fanfiction centers around the challenges brought by the curse.
