For Naruto, it could accelerate his growth not just in terms of power but also in maturity. Spending a long time alone in the chamber, he might have deep self - reflections and come out with a better understanding of his purpose and responsibilities.
One idea could be Naruto using the hyperbolic time chamber to train intensively for a new and extremely powerful jutsu. He could emerge with a whole new set of skills that surprise his friends and foes alike.
Harry Potter himself is very common. Writers often explore what he would do if he had more time in the Time Chamber, like further training in magic or trying to understand his connection to Voldemort better.
One interesting plot could be a character going back in time in the Time Chamber to prevent a major tragedy that happened in the wizarding world. For example, they might try to stop the first rise of Voldemort.
It could also be a result of a powerful curse or blessing. For instance, he might be cursed by an old enemy with the ability to control time as a side - effect, but he then learns to master it. Or, it could be a blessing from a sage or some other powerful being who sees Naruto's potential and gives him this unique ability to help him save the world.
One idea could be to have Naruto find the Ocarina of Time in the Hidden Leaf Village. Maybe it was left there by a wandering traveler from the 'Ocarina of Time' world. Naruto, being curious, starts to play it and unknowingly opens a portal to the world of 'Ocarina of Time'. He then has to navigate this new world, using his ninja skills and making new friends and allies there.
The 'naruto god of time fanfiction' could potentially explore how Naruto's life changes when he becomes the so - called 'god of time'. He might be able to rewrite history in a way that benefits the ninja world. For example, he could stop the Uchiha massacre by going back in time and resolving the conflicts between the Uchiha clan and the Hidden Leaf Village. This would not only save Sasuke from a life of revenge but also change the entire power balance and future events in the Naruto story. It could also introduce new villains or allies who are interested in Naruto's time powers.
I'm not entirely sure if there is a specific 'Naruto Sings Time of Dying' fanfiction. Fanfictions cover a wide range of scenarios and ideas. It could be that such a unique concept exists, but it might also be a very niche or even new idea that hasn't been written yet. You could also try reaching out to Naruto fan communities on social media platforms to ask if anyone has come across such a fanfiction.
One great Tobirama time - travel fanfiction is 'Tobirama's Second Chance'. In this story, Tobirama travels back in time and uses his knowledge to prevent some of the future tragedies in the Naruto world. It's really interesting to see how he interacts with the past versions of the characters.
It could be about many things. Maybe it's a fanfiction that plays with the concept of time in the Naruto universe and involves a character with a unique braid in some significant way.
