If Naruto is in a new scenery, like a more peaceful village, he might develop a calmer side. He won't always be in fight - or - flight mode. Sakura could develop more confidence if she's in a place where her medical skills are highly valued. For Sasuke, if he's in a place with different ideals about revenge, he might question his own motives more.
One idea could be Naruto being transported to a modern-day city. He'd be shocked by the tall buildings and cars. Another could be him ending up in a different ninja village with unique customs. For example, a village that focuses more on stealth and illusion techniques than Konoha. It would be interesting to see how he adapts and uses his skills in these new environments.
A third theme could be renewal. When there's a change of scenery, it can symbolize a fresh start for the characters. They might have new relationships, new goals, or a new outlook on life. This is often seen when the village is rebuilt in a different way after a disaster.
There's also 'Naruto in the Mysterious Land'. In this fanfiction, Naruto is transported to a completely unknown land filled with strange creatures and magic. His ninja skills are put to the test in this new and exciting environment. It offers a fresh take on the Naruto universe.
First, he needs to plan out the changes carefully. Decide which aspects of the story, like characters or plotlines, he wants to modify. Then, he should make sure the changes are consistent with the overall theme of the Naruto world. For example, if he's changing a character's personality, it should still fit within the established ninja culture.
In a 'naruto with sharingan fanfic', Naruto's new power could also change the way battles are fought. With the Sharingan, he can predict his opponents' moves more accurately. This might make some of his previous opponents, who were evenly matched with him before, seem much weaker. It could also force his enemies to come up with new strategies to counter his enhanced abilities, which in turn would change the overall military and strategic landscape of the Naruto universe.
A demonic Naruto could also change the social dynamics. If his appearance became more demonic, some villagers might fear him, while others might see him as a savior. This could lead to a split in the village, with some supporting Naruto and others trying to get rid of him. His friends would also have a hard time as they try to convince everyone that Naruto is still the same person deep down. And his relationship with characters like Sakura and Kakashi would be put to the test as they try to help him control his new powers.
The popularity might come from the unique pairing of Hermione and Fleur. They are both strong, intelligent female characters in the Harry Potter universe. Their combined skills and personalities make for an interesting dynamic. Also, the idea of a change of scenery allows for a lot of creativity. Writers can take them to different magical places and create all sorts of new adventures.
One great fanfiction could be 'Hermione and Fleur's Magical Adventure'. In this, they might go on a journey through different magical lands, encountering unique creatures and spells. Another could be 'The New Scenery for Hermione and Fleur' where they explore a hidden part of the wizarding world. There's also 'Hermione, Fleur and the Mysterious Realm' which has them facing challenges in a previously unknown magical realm.
Naruto's character could develop a sense of pride that he didn't have before. This Super Saiyan 3 form is something extraordinary, and he might start to show it off a bit. But at the same time, he would also have to learn humility. If he becomes too arrogant, his friends might distance themselves from him. So he would be in a constant struggle between showing off his power and being the humble ninja he was raised to be. Also, his leadership skills might improve as he now has a power that others look up to, and he would need to lead by example when it comes to using this power responsibly.
