In some versions of this fanfiction, Harry could use his power over the weather to create a diversion during a battle. He might summon a thick fog to hide his allies' movements or a strong wind to blow away the dark spells of the enemies. By controlling the weather, he becomes a strategic asset in the fight against the forces of evil.
Foxes are quite common. Given Naruto's connection with the Nine - Tailed Fox, it makes sense that in fanfiction, he might be able to control other foxes. They can be used for scouting or as distractions in battles.
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.
In this fanfiction, Naruto's ability to control shadows could be related to his connection with the Nine - Tails. Maybe the power of the Nine - Tails unlocks this new ability within him. He could use the shadows to form shields against attacks, or even to travel quickly from one place to another by using the shadows as a sort of transportation network within the ninja world.
The Akatsuki members might also be antagonists. Since they're after the tailed beasts, Naruto with his additional power of lightning control would be a prime target. They might send their most powerful members like Pain or Itachi to deal with him.
Well, it could be about Naruto using his chakra to control paper in unique ways. Maybe he creates paper constructs for battle or uses it to send secret messages.
In a 'Naruto controls necromorphs' fanfiction, Naruto would bring his own set of values from the Naruto universe. His sense of justice and protection might lead him to try and use the necromorphs for good, like using them to protect a village or an area from other threats. However, he would also have to deal with the fact that necromorphs are grotesque and often uncontrollable creatures in their own right.
Obviously Naruto would be the main character as he has the power to control vacuums. His friends like Sasuke and Sakura could also be involved. Sasuke might be skeptical at first about this strange new ability of Naruto's. Sakura could be trying to find a scientific explanation for it, thinking it has something to do with Naruto's unique chakra nature.
