In fanfiction, Naruto could control water by forming a pact with a water spirit or entity. This is a common trope in many fictional works. The water spirit could grant him the ability to manipulate water in exchange for something. It could be his protection, or his help in solving a problem related to the water spirit's domain. Through this connection, he can then call upon the water and shape it as he desires.
In some fanfictions, Naruto might control water through special training. Maybe he discovers a hidden jutsu or a unique chakra manipulation technique that allows him to bend water to his will. For example, he could learn from a water - based ninja clan or an ancient scroll.
Naruto could develop his water control abilities through intense meditation. By focusing his chakra and mind, he can better understand the nature of water. He may also study the movements of water in nature, such as how rivers flow and how water droplets form. This knowledge would then be applied to his jutsu, gradually improving his control.
In some Naruto fanfictions, Naruto might control minds through special jutsus. For example, he could use a modified version of the Sharingan's genjutsu ability that he somehow acquires. Another way could be by using his strong chakra to influence the minds of others directly, kind of like a mental wave that disrupts or takes over their thoughts.
Well, it could be that in the fanfiction world, Naruto has a special bond with nature spirits which gives him the power to control animals. He might have to enter a trance - like state to connect with the animals' minds and then be able to order them around. For example, he could use this power to make birds act as spies or have wolves guard a certain area.
Well, in some fanfictions, Naruto might have a special chakra ability related to nature that allows him to communicate with plants on a spiritual level. This connection enables him to command them to grow, move, or even use them as a form of defense or attack. For example, he could make vines entangle his enemies or have large trees block incoming attacks.
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.
Well, in certain fanfic concepts, Naruto could control Kyuubi chakra with the help of unique jutsu or seals. For example, he might discover a new sealing technique that allows him to better manage the flow of the Kyuubi's power. This new seal could work in harmony with his own chakra system, enabling him to draw on the Kyuubi's strength without being overwhelmed. Also, some fanfictions might suggest that his strong emotional bonds, like his friendship with his comrades, give him the extra mental fortitude to control such a powerful chakra source.
Well, it could be related to some new jutsu he discovers in the fanfiction world. Maybe he combines his nature transformation with his unique ability to connect with nature. For example, he first creates a bond with the plants that produce the flower petals, and then he can manipulate the petals as if they were an extension of himself. This could be a result of his growth and exploration of new powers beyond what we see in the original series.
Another possibility is that Naruto is given an ancient artifact or power by some wise old character. This power could be directly related to controlling the Iron Sand. He then has to learn how to master this new ability, which might involve some trial and error. He could initially struggle with controlling the Iron Sand, but as the story progresses, he becomes more proficient and uses it in battles against powerful enemies.
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.
