The relationships in the fanfiction would be different. Naruto's friends and allies might react in various ways to his act of killing Kakuza. Some might support him if Kakuza was truly evil, but others might be shocked and question Naruto's actions. This is different from the original where Naruto's actions usually get a more unified positive response from his comrades.
Well, in the original storyline, there might not be a character named Kakuza at all. So right off the bat, this is a new addition. If Naruto kills Kakuza in the fanfiction, it would show a darker side of Naruto perhaps. In the original, Naruto is always about redemption and saving his enemies. But here, if he kills, it's a deviation from his usual character trait.
One possible motive could be that Kakuza has committed some heinous crimes against the Hidden Leaf Village. Maybe he has been involved in secret attacks on the village or has been plotting something really bad that would endanger the lives of many villagers. Naruto, being the protector of the village, would then take it upon himself to stop Kakuza by any means necessary, which unfortunately might end up in killing him.
In the original storyline, Yagura was the Fourth Mizukage who was being controlled by Obito. He was more of a victim. But in this fanfiction, Naruto kills him, which is a huge deviation as Naruto is usually about saving people. In the original, Naruto tries to understand and redeem his enemies, not kill them outright.
Well, in the original Naruto storyline, Minato is Naruto's father and he sacrificed himself to save the village and Naruto. So, in the fanfiction where Minato kills Naruto, it completely goes against this fundamental relationship. It changes the very essence of Minato's character from a self - sacrificing hero to a killer.
In the original, Naruto is the protagonist who is on a journey to become Hokage and gain the respect of the village. If Kushina kills Naruto in the fanfic, then all the dreams and hopes associated with Naruto are shattered. The whole narrative arc of the series is disrupted, and it could lead to a much darker and more despair - filled story for the other characters in the Naruto universe.
A significant difference would be the power dynamics. In the original, Naruto gains power through his own hard work, training, and the power of the Nine - Tails. In a fanfiction where he marries Kushina, there could be new power - sharing elements. Maybe they combine their Uzumaki chakra in unique ways. Also, the social aspect is different. In the original, Naruto is seen as an orphan trying to find his place. Here, he is part of a powerful couple. This changes how the other characters interact with him and how the story progresses in terms of village politics and alliances.
The original Naruto is about growth, friendship, and heroism. Naruto is depicted as a heroic figure who would never harm his family. In this fanfiction, the concept of Naruto as a 'god' and his act of killing his family introduce a very dark and uncharacteristic element. It changes the entire tone of the Naruto world from one of hope and perseverance to a much darker, more tragic one.
It alters the theme of the original Naruto story. The original story often emphasized forgiveness and the power of friendship. In this fanfiction, if Naruto kills Haku, it might shift towards a darker theme of sacrifice and the harshness of the ninja world. This could also change how the other characters develop. For instance, Sakura might view Naruto differently, either fearing him or seeing him as a more decisive and perhaps colder hero. And Naruto himself might struggle with guilt or a new - found sense of power that comes from taking a life, which would be a huge departure from his usual self in the original storyline.
One scenario could be that Orochimaru tries to take over Sasuke's body again. Naruto, being Sasuke's friend, would do anything to stop it. He could use his Uzumaki bloodline powers, like the Adamantine Sealing Chains, to bind Orochimaru and then use a powerful attack to finish him off. Another possibility is that Orochimaru has created a new, even more dangerous experiment that endangers the entire ninja world. Naruto, as the hero, steps up and uses his Sage of Six Paths powers (if he has access to them in the fanfiction) to kill Orochimaru.
It can be different in that it doesn't center around the ninja battles and power struggles as much. Instead, it might focus on the civilian side of things, like their social hierarchies or family dynamics which are not the main focus in the original.
Well, in 'naruto psionic fanfiction', Naruto or other characters have psionic abilities which are not present in the original. For example, in the original, Naruto relies on chakra and ninja techniques, but in psionic fanfics, they can have mind - related powers like telepathy or telekinesis.
