One great fem Naruto time travel to the past fanfiction is 'Naruto: Back to the Beginning'. In this story, the female Naruto has to navigate the past with her knowledge from the future. It's really interesting to see how she changes events that she previously regretted. Another one is 'Fem Naruto's Time - Travel Adventure' which focuses more on her relationships with the other characters in the past and how she uses her skills in a different context.
Naruto's power of the Nine - Tails would be a major factor. In the past, the Nine - Tails was feared and hunted. If Naruto shows up with the power under control, it could change how people view the beast. His chakra reserves, which are huge because of the Nine - Tails, could allow him to perform feats that were previously thought impossible in the past, like quickly rebuilding a village or fending off a large - scale invasion on his own.
One major theme is change. The whole idea of time travel implies change. Fem Naruto aims to change the past, which in turn changes the future. This can lead to exploring different possible futures for the Naruto universe. Additionally, the theme of love often pops up. It could be platonic love for her friends or a different kind of love interest that emerges as a result of her time - traveling experiences. She might find herself falling for someone she didn't expect because of the new circumstances in the past.
Orochimaru's experiments and his knowledge of forbidden jutsu would be far ahead of the time he travels back to. He could use this to his advantage, perhaps by creating new techniques based on the limited knowledge of the past. However, he also has to be careful not to change the future too much as his actions in the past could have unforeseen consequences for his future self.
Their relationship could become more of a peer - to - peer one. Since Naruto already has a lot of knowledge and skills from his future self, he might be able to offer new perspectives to Jiraiya. Jiraiya could see Naruto in a new light and start to rely on him more in certain situations.
He would gain a deeper understanding of the history and the people around him. By experiencing the past first - hand, Naruto could see the motives and the struggles of the older generations. This would make him more empathetic towards characters like Itachi. He would realize that there were many hidden factors behind their actions, and this new - found understanding could shape his character into a more mature and complex individual. His relationships with his friends and allies would also be affected as he could share this new knowledge with them.
Well, their relationship would likely become more confident. Since they are already married, Hinata wouldn't be as shy around Naruto as she was in the original timeline. Naruto would also be more aware of Hinata's feelings and his own for her. He would probably be more protective of her right from the start.
At the start, Mito might see Naruto as an oddity due to his strange clothing and modern - day ninja tools. But as they journey through the past, Naruto's courage in the face of danger impresses her. They might start off as comrades, just trying to figure out how to get back to their respective times. However, as they interact more, they realize that they can complement each other's skills. Mito's sealing techniques and Naruto's combat abilities work well together. This cooperation leads to a growing respect for each other. Over time, they develop a relationship that is a blend of friendship, mentorship (both ways to some extent), and a shared sense of purpose that cements their connection in the past.
Their relationship would likely be more complex in the past. Since they are from the future and already married, they would have a deeper connection. But they would also have to hide it from their past selves. Naruto might be more protective of Sakura in the past, and Sakura would be more confident in their relationship.
Maybe the time travel is caused by a mysterious time - space ninjutsu. In the past, Naruto and Sasuke find themselves in a world where their actions can have a huge impact on the future. The kiss could be a spontaneous reaction to the realization that they are the only ones who truly understand each other across time. As the story progresses, they might try to prevent certain tragedies from happening in the past, all while dealing with their new - found and complicated relationship.
