What are the possible applications of Naruto's ink control in fanfiction?

He could use it for defense. For instance, creating a huge storm to block enemy attacks or a thick fog to hide his village from invaders.

He could use it to unlock metal locks without a key. Just by using his magnetism control, he can manipulate the tumblers inside the lock.

One unique application could be that he uses it to relive his training days and improve his skills even more. He can go back to his time with Jiraiya and learn from his mistakes during training. Another is that he can slow down time during a battle to dodge attacks that are otherwise too fast for him.

He could use it for stealth. For example, he could create paper clones that are much quieter and less detectable than his normal clones. These paper clones could be used to spy on enemies or gather information without being noticed easily.

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.

He could use it for various things. For example, he could create barriers of water to protect himself or others. He might also be able to manipulate the flow of liquids in a chemical experiment in the fanfiction world, leading to new discoveries. Another application could be in firefighting, where he can control any liquid and use it to extinguish fires more effectively.

One interesting application is his ability to create entirely new jutsus by combining different elements. For instance, he could mix fire and wind to create a super - heated blast that's more powerful than either element alone.

Naruto could use chakra strings in fanfiction for communication. He might be able to send vibrations through the strings to other ninja who are also attuned to chakra, like a secret code. Also, in combat, he could use the strings to set up traps. He could string them across a path and when an enemy steps on them, he can either trip the enemy or use the connection to launch a surprise attack.

Naruto might also use his blood control to enhance his physical abilities. For example, he could increase the oxygen - carrying capacity of his blood to boost his stamina. Or he could control the blood flow to his muscles to increase their strength momentarily. This would make him an even more formidable opponent in combat, and these applications would make for some really interesting scenarios in the fanfic.

It could be from some sort of ancient ninja training that was lost and he somehow discovers it. Maybe there's a hidden scroll or a hermit who teaches him this fire - controlling ability.
