One memorable scene could be when Naruto is about to be attacked by a powerful enemy. Kushina suddenly appears, her red hair flowing in the wind, and she uses her chakra to create a shield around Naruto. She stands firm, glaring at the enemy, and says something like 'You will not touch my son.' It's a very powerful moment that shows her determination to protect Naruto.
Perhaps there's a scene where Naruto is being bullied or ostracized in the village. Kushina finds out and she goes around the village, talking to the villagers and making them understand that Naruto is a precious boy. She doesn't let anyone's negative attitude towards Naruto slide and shows her protectiveness by standing up for him in the social aspect.
She might physically stand in harm's way. For example, if there's a threat approaching Naruto, Kushina would put herself between Naruto and the danger. Just like how a mother bear protects her cub.
One common scenario is when they are facing a powerful enemy. Sasuke would put herself in harm's way to protect Naruto. Another scenario could be when Naruto is in an emotional distress. Sasuke would be there to comfort and protect him from any further harm. For example, if Naruto is feeling down because of the villagers' attitude towards him, Sasuke would stand up for him and make sure no one takes advantage of his vulnerable state.
One heartwarming scene could be Kushina taking care of sick Naruto. She might make his favorite soup and sit by his bedside, telling him stories of his father. This shows her love and care for him.
Yes, there are likely some fanfictions out there with this premise. Fanfiction often takes creative liberties with the original Naruto story. Writers might explore how this relationship would change the story's dynamics, character interactions, and plotlines. It could lead to very different character development for Naruto and how he is related to other characters in the Naruto universe.
There could be a scene where a powerful and mysterious ninja appears and tries to put a seal on the Nine - Tails within Naruto to limit its power. Naruto, sensing the danger, immediately activates his Kyuubi Chakra Mode. He would then engage in a fierce battle with this ninja. He would be so focused on protecting the Nine - Tails that he would not back down even when facing seemingly impossible odds. And in a more emotional scene, Naruto might have a conversation with the Nine - Tails inside his mind, promising to always protect it from any harm.
One consequence could be Naruto's emotional breakdown. Since Kushina is his mother, her betrayal would be a huge blow to him psychologically. He might start to doubt himself and his place in the world.
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.
They would likely develop a complex relationship. On one hand, Kushina is his sensei, so there would be a sense of respect and authority. But on the other hand, Naruto knows she is his mother in the original story, so there might be an underlying emotional bond. It could be a relationship where Naruto looks up to Kushina as a mentor but also feels a deep connection that is different from a typical student - teacher relationship.
There might be some fanfictions with such a concept, but this is a rather unorthodox and not in line with the positive themes of the original Naruto series. In the original story, Kushina is Naruto's mother, and their relationship is based on family love and the greater Ninja world narrative.
One reason could be that she lost so much time with Naruto due to her early death in the original story. So in the fanfiction, she's overcompensating for that lost time by being possessive.
