Often, Kushina's son complex is portrayed as extreme protectiveness. She might jump in to defend Naruto at the slightest hint of danger. For instance, if Naruto is about to face a tough opponent in a spar, she may try to stop it.
In some fanfictions, Kushina's son complex can create interesting plotlines. It can be a source of conflict, say when Naruto wants more independence but Kushina is reluctant to let go. It also showcases her strong maternal instincts. This complex can be used to develop Naruto's character as well, as he responds to his mother's intense love and protectiveness, perhaps growing in patience and understanding.
Some fanfictions portray Kushina's angst through her interactions with other characters in the afterlife. She might be angry or sad when talking to Minato about Naruto, blaming herself or him for their son's difficult life. This shows her internal turmoil and angst in a very direct way.
In many Naruto fanfictions, Minato is often portrayed as an even more brilliant strategist and a loving husband. He might be shown using his Hiraishin no Jutsu in creative ways to protect Kushina. For example, in some stories, he uses it to surprise her with little gifts or to show up just in time when she's in danger.
Obviously, Naruto is a central character. Kushina herself often appears, either in flashbacks or in some magical - like resurrected form. Minato, Naruto's father, is also common as he is closely related to Kushina. Then there are Naruto's friends like Sasuke and Sakura. They might play different roles, for example, Sasuke could be more involved in helping Naruto understand his mother's side of the family.
The 'naruto son of evil kushina fanfiction' could potentially be about a lot of things. It may start with a different backstory for Kushina, like she was influenced by some dark force which made her 'evil'. Naruto, being her son, might then be ostracized or have a difficult path in the ninja world. It could also delve into how Naruto discovers the truth about his mother and whether he tries to change her or just accepts the situation and forges his own path. There could be new characters introduced who either help or hinder Naruto in this new scenario.
The idea of Naruto being the secret son of Kushina and Mito in fanfic is a fascinating deviation from the original Naruto narrative. Fanfic authors sometimes like to break the norms and create alternative storylines. This particular concept could potentially change a lot of the story's dynamics. For example, it could lead to different power inheritances or different relationships with other characters. But it's crucial to remember that this is a fan - made concept and not based on the official Naruto storyline which clearly states Naruto's parents as Kushina and Minato.
Typically, it's portrayed as a very deep and affectionate mother - son love. Kushina's love for Naruto is shown as selfless and all - encompassing, even from beyond the grave. Naruto, in turn, has a great admiration and love for his mother that he didn't get to experience fully while she was alive. In some fanfics, this love is also shown through their shared Uzumaki heritage, with Naruto feeling a special connection to his mother because of it.
He'd be more confident. Growing up with Fugaku and Kushina, he'd have a strong family support system. He wouldn't have the same insecurities as in the original story. He might also be more of a natural leader, inheriting Fugaku's leadership skills from the Uchiha clan and Kushina's strong spirit.
In such a fanfiction, the relationship between Naruto and Kushina would be one of mother - son love and mutual respect. Kushina would be protective of Naruto and proud of the man he has become. Naruto would look up to Kushina and value her wisdom. With Hinata, Naruto's relationship would be that of a loving couple. Hinata would support Naruto in all his endeavors. When it comes to Kushina and Hinata, Kushina would likely see Hinata as a worthy partner for Naruto and Hinata would respect Kushina for being Naruto's mother and a strong kunoichi.
Another aspect could be that the fanfiction delves into how Kushina's presence affects Naruto's relationships with others. For instance, his relationship with Sasuke could be different. With a strong maternal figure in his life, Naruto might be more stable emotionally and be able to approach Sasuke in a more understanding way, which could potentially change the whole dynamic of their rivalry and friendship.
