In the fanfiction, the plot could revolve around Naruto being influenced by a powerful and evil organization. They manipulate him into believing that the only way to bring peace is through force and killing. As he becomes a cold - blooded killer, we would see him going against his former comrades. There would be intense battles where Naruto uses his new - found ruthless tactics. His character arc would be a dark descent from a hopeful hero to a feared killer.
One possibility could be a great tragedy that befalls him. For example, if all his friends were brutally killed in front of him by an enemy he couldn't defeat at that time. This might shatter his belief in the goodness of the world and drive him to become cold - blooded in order to seek revenge. He would start to see killing as the only way to get justice.
In this fanfiction, Naruto becoming a guardian might mean he has to learn new rules and powers related to guardianship. He could start by befriending other guardians and learning from them. His journey would be about not only protecting but also understanding this new role. He might face challenges from those who don't trust a ninja in a guardian's role, but he'd prove himself with his determination and strength.
Well, the plot could involve Naruto getting tired of the shinobi life. He might start hanging out with the wrong crowd in the village, like some small - time thugs. He could use his ninja skills in illegal ways, for example, stealing valuable scrolls not for the good of the village but for his new 'gang'. His friends like Sasuke and Sakura would be shocked and try to bring him back to the right path.
Some writers may be attempting to analyze the character from a different psychological perspective. By portraying Naruto as a cold - blooded killer, they could be exploring how his upbringing or the events in the Naruto universe could have potentially led to a different, more sinister outcome. It might also be a form of creative rebellion against the traditional view of Naruto as a hero. However, this is a very extreme deviation from the original character, and not all fans would be receptive to such a portrayal.
The plot could start with Naruto discovering his true heritage as the son of King Cold. This would shock the ninja world. He might then have to deal with people's fear and mistrust of him. Meanwhile, he could start to develop some of King Cold's powers, like the ability to survive in extreme cold or have some sort of energy - based attacks similar to those in Dragon Ball. And he would have to decide whether to embrace his new identity or reject it and continue to be just a ninja.
One common plot element could be a character, perhaps Naruto himself, being corrupted or forced into a life of killing. Another might be the exploration of the darker side of the ninja world, like the underbelly of the Hidden Villages. There could also be a focus on revenge as a motivation for the cold - blooded killing.
No. Naruto is known for his warm - hearted and determined nature in the original series. Fanfiction that portrays him as a cold - blooded killer goes against the fundamental character traits that the majority of fans love about him.
Well, in this fanfiction, Naruto could start off as an outcast in the High School DxD world because of his different upbringing. However, his determination and strong will would soon attract the attention of the main characters. He could form an alliance with Issei and the others. Naruto's ability to sense danger and his combat experience would be a great asset. For example, when facing powerful enemies, he could quickly analyze their weaknesses and come up with strategies, just like he did against the Akatsuki in his own world.
If Naruto becomes a Joker fan in the fanfiction, his new look could be really different. He would probably ditch his orange jumpsuit for something more in line with the Joker's style. A long, tattered purple coat perhaps, with some dark makeup around his eyes to give him that menacing look. His shoes could be replaced with some clown - like shoes, and he might carry around a few 'joker - ish' accessories like a deck of cards or a fake flower that sprays water. His overall appearance would be a blend of his ninja - like physique and the Joker's flamboyant and chaotic style.
The plot could involve Naruto using his ninja skills in the world of exorcism. He might use his shadow clone jutsu to outnumber demons. For example, he could send clones to different areas to search for and fight demons while he focuses on the stronger ones. His Rasengan could be modified to have an exorcising effect, perhaps by infusing it with spiritual energy.
