Writers keep it fresh by changing Naruto's relationships in each loop. Maybe in one loop, he becomes best friends with Sasuke right away, or he has a different relationship with his teachers. This alters the dynamics and keeps the story engaging. Also, they might change the rules of the time loop as the story progresses. At first, it seems like Naruto has to relive the same day, but later it becomes more complex, like he has to change specific events in different time periods to break the loop.
They often introduce new characters or bring back old ones in unexpected ways. For example, a minor character from the original series might turn out to be key to breaking the time loop.
In some fanfictions, a time loop might be caused by a powerful curse. The twist comes when Naruto discovers that the only way to break it is by making a huge sacrifice, like giving up his dream of becoming Hokage. This forces him to re - evaluate his priorities and makes for a very interesting read. It adds a new layer of depth to his character as he struggles with this difficult choice.
Writers often develop Naruto's character by emphasizing his growth in understanding Itachi. At first, Naruto might be full of anger towards Itachi because of what he did to Sasuke. But as the fanfiction progresses, he could start to see the bigger picture and become more empathetic. For Itachi, his character can be developed by showing more of his internal struggle. He has to balance his loyalty to the village with his love for his brother.
Some writers justify it by creating a situation where Sasuke has to make a great sacrifice. For example, he might give his life to protect Naruto or the Hidden Leaf Village from an overwhelming threat. His selfless act in these scenarios is seen as a way to atone for his past mistakes and show his growth as a character.
Writers often portray their relationship as a contrast. Unfresh sans is usually more serious and reserved, while fresh sans is carefree and energetic. They might start as two characters who don't understand each other but gradually develop respect.
Sasuke could also be a character who breaks the time loop. He is highly intelligent and has a thirst for power and knowledge. If he realizes that he is in a time loop, he would likely be very intrigued and start investigating. His Sharingan might give him some insights into the nature of the loop and help him find a way to break it.
First, create an interesting premise for the time loop. It could be a curse, a scientific experiment gone wrong, or a mysterious force. Then, focus on the character's growth. As they repeat the loop, they should learn something new each time. Also, vary the events in the loop slightly to keep it engaging.
The time loop in Evangelion time loop fanfiction affects the plot in multiple ways. Characters get the opportunity to redo actions, so they can avoid past mistakes. This might mean that battles with Angels are fought differently. Also, relationships between characters can be rewritten. If Shinji, for example, has a different attitude towards Asuka in a new loop, it will influence how they interact and the events that follow. It basically gives the story a chance to deviate from the original path and explore new storylines.
They often combine different traits from existing Naruto characters. For example, a new character might have Naruto's determination and Sasuke's cool - headedness. Or they give the character a unique power that is not in the original series, like the ability to manipulate light in various forms. Also, they might create a character with a strange backstory, such as being raised by a mythical creature in the Naruto world.
They create unique storylines by mixing different elements from the Naruto world. Maybe they combine a forgotten ninja art with a modern - day problem in the shinobi world. Writers also like to give Naruto new goals that are different from what he had in the original series. This could be something like trying to reform the entire ninja education system. They also add new characters that bring fresh conflicts and relationships into the story.
Writers can keep the characters in - character by closely studying their original personalities. For Naruto, his core traits are his determination and his loyalty.
