One possible plot twist could be that Naruto's smoke jutsu actually hides a powerful secret technique. For example, instead of just being a simple smoke cover, it could be a way to teleport or to create clones that are undetectable within the smoke. Another twist might be that an enemy figures out a way to turn Naruto's smoke jutsu against him, perhaps by using the smoke to spread a harmful gas or illusion that affects Naruto when he uses the jutsu.
Naruto might become more strategic. Since the smoke jutsu can be used for both offense and defense, he would learn to time it better. For example, he could use it to blind opponents before launching a surprise attack. This would make him seem more calculating rather than just relying on brute force.
The 'Naruto Cataclysm Justu' in fanfiction often involves extremely powerful and destructive techniques. It can be a unique creation by fans to add more high - stakes action to the Naruto universe. For example, it might be a jutsu that can cause massive earthquakes and tsunamis, changing the entire battlefield.
In certain Naruto fanfics, the authors might give Naruto the habit of smoking to show his more grown - up or rebellious side. It could be part of a darker or more mature interpretation of his character. But it's important to note that this is not in line with the canonical Naruto we know from the anime and manga, which focuses on his ninja skills, his journey to become Hokage, and his relationships with his friends.
Characters can be both physically and mentally affected. Physically, they might be injured or killed if caught in the blast of the Cataclysm Justu. Mentally, they could be traumatized by the destruction it causes.
A fanfic could also explore Naruto using the Smoke Jutsu for a rescue mission. Suppose some of his friends are trapped in a building surrounded by enemies. Naruto uses the Smoke Jutsu to cover the area. The smoke is so thick that the enemies can't see. Then he sneaks into the building, rescues his friends, and they all escape under the cover of the remaining smoke.
Well, Naruto could use the Smoke Jutsu to create illusions within the smoke. He might make it seem like there are a hundred Narutos emerging from the smoke, scaring his enemies. This would be a creative use of the basic Smoke Jutsu, adding an element of deception.
It could be a new character, like a young orphan who discovers their Smoke Release ability and then tries to find their place in the ninja world. They might face discrimination at first because of their unknown origin and unique power, but eventually prove themselves.
The Smoke - Smoke Fruit might also create new alliances. Characters who recognize the potential of the fruit's power might team up with the one who has it. This could lead to unexpected partnerships and rivalries, completely changing the political and power landscape in the Naruto world. For example, a group of weaker ninjas could band together with the Smoke - Smoke Fruit user to stand up against stronger clans.
A fanfic could focus on a group of ninjas who specialize in Smoke Release and form a special unit. They are sent on secret missions where their ability to blend in with the smoke and move undetected is crucial. Their relationships and how they work together could be explored, as well as the challenges they face against opponents with different elemental abilities.
