Naruto might be able to transform matter into energy and vice versa. This would give him an incredible power source. He could convert the surrounding air into a powerful blast of energy, or take a blast of enemy energy and turn it into harmless matter, like water or sand.
He could potentially develop the power to heal any injury instantly. Since DNA controls the building and repair of the body, by manipulating it, Naruto might be able to direct cells to regenerate at an accelerated rate, similar to how some real - world organisms can regenerate lost limbs.
In fanfiction, Naruto could potentially control a wide variety of animals. For example, he could control small and nimble animals like squirrels. Squirrels are quick and resourceful, which could be useful in various situations. He may also have control over larger animals such as bears. Bears are strong and intimidating, and Naruto could use their strength for protection or combat. Another possibility is that he can control dolphins if the story involves water - related scenarios. Dolphins are intelligent and friendly, and they could help Naruto in underwater missions or just be his companions in a more aquatic - themed fanfiction.
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.
He could develop the ability to combine the power of the Sharingan with the Nine - Tails' chakra. Maybe he could use the Sharingan to better control the Nine - Tails' power, for instance, seeing the flow of the chakra inside him more clearly. This could lead to new jutsu that are a fusion of Uchiha and Uzumaki techniques.
He could develop the ability to use the Six Paths Sage Mode more effectively. Since the Rinnegan is related to the Sage of Six Paths, it would enhance his connection to that power. He might also gain the ability to create chakra chains similar to those of the Uzumaki clan but with an added Rinnegan - powered twist.
He could develop the ability to transform into a more powerful form that combines the features of all nine tailed beasts. Maybe he could have nine tails of different colors or shapes, each representing a different tailed beast, and with each tail comes a special power.
He could develop enhanced physical abilities. Since he can't rely on chakra, he might focus on building muscle strength and speed through intense physical training. He could also become an expert in using various ninja tools. For example, he could master the use of shuriken and kunai in ways that others haven't. Another ability could be better observational skills. He'd need to be more aware of his surroundings and his opponents' movements without the help of chakra - based sensing techniques.
Well, there are several platforms. Fanfiction.net is a classic. It has been around for a long time and has a vast number of Naruto fanfictions. AO3 is also a good option. It not only has a great search function but also allows for more diverse and complex fanfictions. You could also try Wattpad. While it has a wide range of stories, you need to search specifically for Naruto fanfiction, but you might find some hidden gems there.
He could gain the ability to absorb chakra on a much larger scale. With his greedy nature, he might use this to hoard chakra from others, making himself super - powerful. He could also gain the power to control the six paths, which he might use to dominate others rather than for the common good.
He could develop the ability to use the Preta Path more effectively. This path allows the user to absorb chakra, and Naruto could use it to nullify enemy attacks that rely on chakra. For instance, if an enemy uses a powerful fire - style jutsu that is chakra - based, Naruto could absorb the chakra of the attack, rendering it useless.
