In some fanfictions, Naruto might control ink through special chakra manipulation. He could use his own unique chakra nature to give life to the ink, making it move and form shapes as he desires. For example, he might infuse his wind - style chakra into the ink to make it flow like a gentle breeze, or use his strong willpower to direct the ink's movements.
One possible application is for stealth and deception. Naruto could use the ink to create illusions of himself or other objects, confusing his enemies. For example, he could make it seem like there are multiple Narutos on the battlefield.
He could control elements like water, which would allow him to create powerful waterfalls or form water - based defenses. Fire is also a possibility, enabling him to shoot out intense flames. Another type could be earth, where he can manipulate the ground to create barriers or traps.
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.
It could also have implications for the Hulk himself. Usually, the Hulk is a wild and uncontrollable force. But with Naruto in control, he might be able to be used in more positive ways. The Hulk could be directed to help rebuild instead of just destroy. And from a character development perspective, the Hulk might learn to control his rage better under Naruto's influence, and Naruto might learn new things about power and responsibility from having to control such a powerful being.
Another option is to follow Naruto fanfiction groups on social media platforms. People often post links to their favorite fanfictions there. Just be sure to check the content carefully as not all fanfictions are of the same quality, but you might find some really cool Naruto ink fanfiction this way.
