The story could start with Naruto showing amazing potential early on. Kushina would be proud and continue to train him. As he grows, he might face challenges that are different from the original Naruto. Maybe stronger enemies would target him earlier. But with his godlike powers and Kushina's guidance, he would overcome them easily.
In such a fanfiction, Naruto being godlike could mean he has extraordinary abilities. Kushina might raise him with a lot of love and also train him rigorously. He could quickly master things like chakra control and ninjutsu. This Naruto could be more of a prodigy and perhaps change the entire ninja world much faster than in the original story. He might also inherit some of Kushina's unique traits in a more amplified way.
I'm not sure specifically as there could be many different plots in such a fanfiction. It might involve Naruto having some god - like powers but being rejected or abandoned by his mother Kushina for various reasons, perhaps due to fear of his power or some dark influence.
Maybe an ancient evil that has been awakened. This entity is so powerful that it takes the combined godlike powers of Naruto and Kushina to stand against it. The antagonist could have some connection to the origin of chakra or an old, forgotten curse.
In a 'Naruto raised by Kushina' fanfiction, it could be a heartwarming story. Kushina would likely be a very protective and loving mother. She'd teach Naruto about the Uzumaki clan heritage from a young age. Naruto might grow up more confident and less of an outcast as Kushina would be there to shield him from some of the village's harshness.
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.
One possible plot could be that Naruto grows up with a strong mother figure. Kushina might teach him early on about his Uzumaki heritage, which could make him more confident. He might also learn her unique chakra control techniques much earlier, leading to him being more advanced in his ninja skills at a younger age.
In this fanfiction, their relationship would evolve in a very special way. Naruto, with his newfound godlike status, would be more in tune with Kushina's emotions. He would be able to sense if she was having a bad day or if the baby was causing her discomfort. He would use his powers to comfort her, like creating a warm, soothing energy around her. Kushina would be in awe of Naruto's growth but also rely on him more. They would talk about how to raise their child, with Naruto's experiences as a hero and Kushina's wisdom combining to form a unique parenting plan for their soon - to - be - born baby.
Well, a frequent theme is the exploration of Naruto's new - found godlike abilities in relation to his love for Kushina. It could be that his powers are somehow connected to his feelings for her. Another common aspect is the emotional healing that comes from their relationship. Naruto may have had a tough life, and his connection with Kushina in these fanfictions can be a source of comfort and growth. Additionally, there might be themes of heroism, where Naruto, with his godlike powers, is seen as a hero in Kushina's eyes and vice versa.
There could be a fanfiction where Naruto discovers that Kushina had a secret technique that she never got to fully use. Naruto, being the determined character he is, masters this technique and becomes an even greater hero. This could involve him using the technique to save his friends from a seemingly impossible situation, like a powerful enemy attack on the village.
