Obviously Naruto is the main character as it's in the title. But often, characters like Sakura, Hinata, and even Kakashi might be involved. Sakura could be the one Naruto tries to impress with his godlike and pervy antics. Hinata might be the shy observer or the one Naruto has some special pervy - like moments with. And Kakashi could be the one who has to keep Naruto in line when his pervy side goes a bit too far while also being amazed by his godlike powers.
Naruto is the central figure, of course. However, in these fanfictions, Tsunade might also play a role. Given her status and power, Naruto's godlike abilities and pervy nature could create some interesting interactions with her. Also, Sasuke could be involved. He might be annoyed by Naruto's pervy side but also respect his godlike powers. Their relationship could be explored in a new light within this type of fanfiction.
Obviously Naruto is a main character as it's a Naruto fanfiction. His character with the godlike mokuton powers would be central to the story. Sasuke might also be involved. Their relationship could be explored further, especially with Naruto's new - found power. Sasuke might be in awe, jealous, or try to compete with Naruto in different ways.
Obviously Naruto himself. Since it's about his godlike speed, he's the central figure. Sasuke is also likely to be involved as his rival. Their interactions, with Naruto's speed being a major factor, can create intense and exciting storylines.
Obviously, Bella is a main character. Edward is often still involved as her love interest. Even if Bella is godlike, their relationship can be explored in new ways, like how Edward copes with Bella's new - found power.
Well, Naruto is obviously a main character in most of these. But there could also be Sasuke. He might be either an ally or an adversary in relation to the dagger. For example, if the dagger has a power that can either be used for good or evil, Sasuke could be tempted by its darker potential.
Some fanfictions might also include characters like Kakashi in important roles. As Naruto's former teacher, he could be a guiding figure or someone who has to adapt to Naruto's new level of power. He might also be involved in trying to keep Naruto's power in check if it starts to have negative effects on the ninja world.
Naruto himself is often a main character in naruto helmet fanfiction. Since he is the protagonist of the original series, it makes sense that he would be involved with a special helmet in fan - created stories. He could discover the helmet's powers and use them to become even stronger.
Naruto himself is often involved. Since he's the main character of the original series, in fanfiction with loopholes, he might use some loophole to achieve his goal of becoming Hokage faster or getting stronger in a unique way. Sasuke could also be a main character in such fanfictions. He might find a loophole to deal with his quest for revenge or his power - seeking in a different manner.
In many Naruto scream fanfiction, Kakashi Sensei can also play an important role. He might be trying to teach Naruto how to control his scream in a more strategic way, or he could be using Naruto's scream as a signal during a mission. Also, characters like Jiraiya might be involved. Jiraiya could be training Naruto to use his scream as a form of attack or defense, as part of some new and unique jutsu.
Definitely Naruto as the victim of hypothermia. Shikamaru could also be involved. He might be the one strategizing the rescue mission, using his intelligence to figure out where Naruto could be in the cold environment. And Hinata might be there too, her concern for Naruto adding an emotional aspect to the story.
Obviously Naruto himself is a main character. He is the one with the pacemaker so he is central to the story. Sasuke might also be involved. He could be initially skeptical of Naruto's new situation with the pacemaker but then come around to help. Sakura too, as a medical ninja, she could play a crucial role in understanding and perhaps even trying to modify the pacemaker.
