It could also be a new power he discovers. In many fanfictions, the author gives Naruto unique abilities that are not part of the original story. So, this could be a power that is specifically designed to deal with the heartless. Maybe it has something to do with his connection to the nine - tailed fox. The fox's power might be modified or used in a new way to control these heartless entities.
Well, it might be related to his ability to understand and empathize with others. Naruto has a big heart and can often see the good in people. Maybe in this fanfiction, he uses this empathetic side to connect with the heartless on some level, and then gain control over them. He could be reaching out to whatever small bit of 'heart' or consciousness they might still have.
In fanfiction, it could be through his strong chakra control. Naruto has always had amazing control over his own chakra, and perhaps he can manipulate the 'heartless' by infusing his chakra into them in a certain way, influencing their actions or behaviors.
Well, in some fanfictions, Naruto might control the heartless through his strong will and the power of his chakra. Maybe he uses some new jutsu he developed specifically for this purpose.
Another issue could be resistance from other forces. There might be some dark entities or villains who don't want Naruto to control the heartless. They could try to stop him, either by directly attacking him or by using their own powers to counteract his control methods.
A great 'Naruto Control Heartless' fanfic is 'Naruto: Heartless Redemption'. This story delves deep into Naruto's psyche as he tries to control his newfound heartless nature. It starts with Naruto experiencing a great loss that causes him to shut off his emotions. As the story progresses, he has to learn how to balance this new side of him with his true self. The fic also has some amazing fight scenes where Naruto uses his heartless state to his advantage, making for a really engaging read. It also explores the relationships he has with his friends and how they react to this change in him.
One challenge could be that the heartless have a very different nature compared to the beings Naruto is used to dealing with. Their lack of emotions might make it difficult for him to find a way to connect and control them.
The main character is usually Naruto in 'Naruto Control Heartless' fanfics. However, other characters like Jiraiya can be crucial too. Jiraiya might be shown as a mentor figure trying to understand what has happened to Naruto and help him. Additionally, characters from the Akatsuki, like Itachi, can be involved as their motives and actions can be intertwined with Naruto's new heartless self. For example, Itachi's past actions and secrets could have an impact on how Naruto views the world in his heartless state.
Well, it could change a lot. For example, he might be able to prevent some of the tragic events that happened in the original. He could stop the deaths of his comrades like Jiraiya. He could also reshape the ninja world order more quickly, maybe by eliminating the root cause of the shinobi wars directly.
In some fanfictions, it could be due to a new jutsu he discovers. Maybe during a secret training session in an ancient scroll, he finds a forbidden technique that allows him to control people.
Well, in some fanfictions, Naruto might gain the ability to control nature through intense training with a hermit or some ancient spirit. For example, he could be led to a hidden grove where the essence of nature is concentrated, and by communing with it over time, he gradually unlocks the power to control nature.
Maybe it could be through some sort of magical jutsu. Naruto is known for his unique ninjutsu skills in his own universe. He might have developed a new jutsu that allows him to connect with and control the Hulk's mind. For example, it could be a jutsu that detects and manipulates gamma radiation, which is what created the Hulk. Or perhaps he found a way to use his chakra in a new way to interface with the Hulk's rage - powered form.
Another possibility is that Naruto acquires the ability to control the weather from a powerful artifact. He might stumble upon an ancient relic during one of his adventures. This artifact has the power to control the weather, and once Naruto touches it or figures out how to use it, he gains this extraordinary ability. It could be that the artifact was created by a long - forgotten civilization that had mastered the art of weather manipulation.
