One interesting aspect could be how Naruto's presence affects the past. Since he has knowledge of the future, his actions could potentially change the future in unexpected ways. And with Kushina raising him, the dynamic with other characters like Jiraiya would also be different. Jiraiya might see a more confident and skilled Naruto, which could lead to different training methods and adventures for Naruto. Also, Naruto's relationships with his peers like Sasuke and Sakura would start from a very different place, as his upbringing by Kushina would shape his personality and values differently.
Well, Naruto's growth as a ninja would be different. Kushina was an Uzumaki, so she could teach Naruto a lot about their clan's techniques and heritage. He might not have to struggle as much to find his identity and power. Also, the time travel element could introduce new villains or change the way existing ones are dealt with. For instance, if Naruto has the knowledge of future events, he could use it to outwit his enemies and protect the village in ways he couldn't in the original story.
In this type of fanfiction, the time travel aspect could bring in many changes. Maybe Naruto travels back in time and gets to be raised by Kushina who was still alive. This would completely change his upbringing. He could be trained by Kushina and Minato together, which would make him an even more formidable ninja at a younger age. And his relationship with the other villagers would be very different as he would have the love and protection of his parents.
A possible plot could be that Naruto and Kushina are sent back in time due to a powerful jutsu gone wrong. Once in the past, they decide to prevent the Nine - Tails attack on Konoha. Kushina, with her knowledge of sealing techniques and Naruto's combat skills, could work together to stop the masked man who released the Nine - Tails. This would save many lives and change the future for the better.
In a 'Naruto Raised by Kushina' fanfiction, the relationship between Naruto and the other villagers could be very different. Kushina would likely be very protective of Naruto, and this might change how the villagers view him. They might see him more as an extension of Kushina, who was respected in the village. Also, Naruto's growth as a ninja could be more focused on his Uzumaki abilities, like strong chakra control and unique jutsu that Kushina could teach him, rather than just his Jinchuriki status.
In a Naruto and Kushina time travel fanfiction, their relationship dynamics would be fascinating to explore. Kushina could see Naruto as he is now, a powerful ninja, and Naruto would get to experience his mother's presence in a new way. They might team up to train together, with Kushina teaching Naruto some of her unique Uzumaki techniques that were lost over time. This could lead to Naruto becoming even more powerful and having new skills to face his enemies.
Well, one possibility is that Naruto with the Rinnegan could use his newfound power to protect Kushina during their time travel. Maybe he can prevent some of the tragedies that happened in the past. For example, he could stop the Nine - Tails attack on the village by controlling the beast in a more efficient way with his Rinnegan powers.
One interesting plot could be Naruto finally getting to meet his mother Kushina in a time travel scenario and learning about his family's past directly from her. He might get some special training from Kushina that only she could provide, like learning some unique Uzumaki clan jutsu.
In some 'naruto and kushina time travel fanfiction', a cool plot point is Naruto and Kushina teaming up in the past. They could use their combined skills to change certain events. For example, they might be able to prevent some of the tragedies that occurred in the original story, like the Uchiha massacre. Naruto could use his knowledge from the future, and Kushina with her strong chakra, would be a great duo.
One possible plotline could be that Naruto discovers a powerful time - travel jutsu. He decides to use it to save his mother Kushina from her tragic fate. Maybe he arrives in the past just in time to prevent the Nine - Tailed Fox attack on the village that led to Kushina's death. He could team up with a younger version of his father Minato and together they fight off the masked man who was behind the attack.
Jiraiya could also be one of the main characters. He was Naruto's mentor and had a connection with Kushina's family. He could play a role in helping them adjust to the time travel and also use their knowledge to his advantage in some ways, like getting intel on future threats.
Obviously, Kushina herself would be a central character. Minato could also be involved, perhaps in a complex relationship triangle with Naruto and Kushina. Then there are other female ninjas like Tsunade. She might be intrigued by Naruto's time - traveling knowledge and get involved in the story. Sakura could also be a potential character. If she somehow gets dragged into the time travel, she might have her own role in the harem - like situation around Naruto.
