Naruto controlling iron may also have implications for the overall world - building in the fanfiction. The availability and manipulation of iron could impact the economy and technology of the ninja world. Maybe new types of iron - based ninja tools are developed, or there are changes in how villages mine and trade iron resources.
It could also change his relationship with other characters. Some might be in awe of his new power, while others might be jealous or fearful. For example, his rivals might see him as an even greater threat now and try to find ways to counter his iron - controlling abilities. This could lead to new story arcs centered around power struggles.
One implication is that it changes his fighting style. Instead of relying solely on his Rasengan or Shadow Clones, he can now use the Iron Sand for both offense and defense. He could create Iron Sand shields or use it to immobilize opponents, adding a new dimension to his combat abilities.
When Naruto controls minds in fanfiction, it can have a significant impact on the Naruto universe. It can rewrite the moral code of the story. Is it right for him to control someone's mind? This ethical dilemma can create complex storylines. It can also make Naruto a more complex character, as he has to deal with the consequences of using such a powerful ability.
One consequence could be that it makes him an outcast. Controlling the dead is often seen as a dark and forbidden art, so his friends and allies might be afraid of him or turn against him.
One potential application is in offensive combat. Naruto could shape the gold dust into sharp projectiles and launch them at his foes, like shurikens but made of gold. Also, he could use the gold dust to immobilize opponents by binding them with it, as it can be manipulated to his will. In the fanfiction, this would make him a more versatile fighter, able to adapt to different battle situations with this new ability.
One possibility is that it could be related to some ancient bloodline limit that was dormant in Naruto all along and somehow got activated. Another could be that he received some sort of special training or exposure to a unique chakra source that granted him this power.
The use of chakra chains by Naruto in fanfiction could also have implications on his character development. It could represent a new level of maturity or power for him. He may start to see himself in a different light, more confident and in control. This new ability could also make him more introspective as he tries to understand the origin and full potential of the chakra chains. It could even lead to him exploring new aspects of his chakra nature that he hadn't considered before, which in turn could open up new paths for his growth as a character.
One implication could be in the area of healing. If Percy can control blood, he could potentially direct it to areas of the body that need repair. For example, if someone has a cut, he could make the blood clot faster by controlling its flow and the platelets within it. This would make him a very valuable asset in any medical emergency within the world of the fanfiction.
One implication could be in combat. He could potentially use the blood of his enemies against them. For example, if an opponent is bleeding, he could make the blood blind them or make their movements sluggish by interfering with the normal blood flow.
There could be a power struggle within the wizarding world. Some pure - blood families who have long held influence in the Wizengamot might oppose Harry's control. This could lead to internal conflicts, maybe even a split in the wizarding community between those who support Harry and those who don't.
One potential power - up could be increased speed. Lightning is fast, so Naruto might be able to move at lightning - like speeds. Another could be enhanced strength in his attacks, as lightning can add a powerful jolt to his punches or kicks.
