A great plotline is her relationship with the other female ninjas in Konoha. For instance, how she became friends with some of them or how they supported each other. Also, fanfics could explore how Kushina's Uzumaki heritage affected her relationships within the village in more detail. This could involve her being seen as both an asset and a potential threat due to her clan's power. It could also show how she overcame any prejudices or suspicions from others. This would make for a really engaging and complex story.
One interesting plotline could be Kushina's time as a genin. Maybe she had some unique adventures or challenges during her early days as a ninja. Another could be her interactions with other Uzumaki clan members who might have had different powers or knowledge.
Some fanfics might have a plotline where Kushina has to use her sealing techniques in unexpected ways. For example, to stop a powerful and ancient evil that has been awakened. This would not only showcase her skills but also her intelligence and resourcefulness. It could also lead to her forming alliances with other characters she might not have otherwise interacted with, creating new and interesting character dynamics.
One interesting plotline could be Kushina's influence on Naruto's chakra control. Since she was a jinchuriki too, fanfics might explore how she could have taught Naruto some unique techniques related to the Nine - Tails' chakra if she had been alive longer.
One of the main themes is love. Not just the mother - son love between Naruto and Kushina, but also how Kushina's love for Naruto can be a driving force in the story. For instance, in some fanfics, Kushina's love gives Naruto the strength to overcome great challenges. Also, the theme of sacrifice is common. Kushina sacrificed herself for Naruto, and fanfics often expand on this idea, showing how Naruto honors her sacrifice and what it means for his character development. In addition, there's often a theme of discovery, where Naruto discovers more about his mother and his own identity as an Uzumaki.
One great fanfic could be 'The Uzumaki Legacy'. It delves into how Naruto and Kushina's relationship might have been different if Kushina had survived. It shows Naruto learning more about his mother's past and how it could have influenced his journey as a ninja. Another is 'Uzumaki Bonds' which focuses on the strong family bond between them, even in the face of the challenges Naruto faces in the Naruto universe.
One possible plotline could be Kushina teaching Naruto some basic ninja skills in secret. Since Naruto is so young, it would be a really cute and heartwarming scenario, with Kushina being a loving and protective mother. Another could be Naruto accidentally stumbling upon some of Kushina's old memories or secrets related to the Uzumaki clan, which then sets off a chain of events that involve both of them on an adventure within the village.
Another reason is the emotional depth. Kushina was a powerful and loving character. Writing fanfics about her and Naruto allows for a lot of emotional storytelling. There can be so many different ways to show their love for each other, from her protecting him in new ways to her teaching him things that he missed out on. It's a way for fans to explore different emotional landscapes within the Naruto world.
There are fanfics that center around the Uzumaki clan's origin. Some might describe how they came to be so powerful in sealing. A really good one could be a story where the Uzumaki clan members who survived the destruction of their village, other than Naruto's mother, come back and help Naruto understand his heritage better. They could teach him things that even Jiraiya didn't know about the Uzumaki.
One interesting Clan Uzumaki fanfic could be 'The Uzumaki's Resurgence'. It focuses on a young Uzumaki descendant who discovers hidden powers within the clan and uses them to protect the village. Another good one is 'Uzumaki Legacy', which delves into the ancient secrets of the clan and how they are passed down through generations.
One plot idea could be Jiraiya training Kushina. Since he was a great ninja and had a lot of knowledge, he could pass on some unique jutsu or survival skills to her. This would not only strengthen Kushina but also create a bond between them based on mentorship.
One interesting plotline could be Naruto finding a hidden journal of Kushina's that reveals secrets about their family or the village. Another is Kushina guiding Naruto in his dreams to master a new jutsu.
Another plotline could be that Naruto discovers he has a connection to an ancient and powerful clan that was thought to be extinct. This new connection could bring him new allies, new jutsu, and a whole new set of challenges as he tries to balance his loyalty to Konoha with his newfound heritage.
