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.
Using the smoke jutsu could make Naruto more aware of his surroundings. He has to be careful not to get caught in his own smoke or use it in a way that doesn't give away his position to smarter enemies. This would develop his observational skills. Also, if he uses the jutsu to rescue people by creating a smoke screen to hide their escape, it would show his growth as a hero who not only fights but also protects. He could start to be seen as more of a tactician and a selfless shinobi, which would be a big step in his character development.
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.
His character could develop in a more spiritual way. If the pipe has some sort of special power or significance, it could lead Naruto to explore the spiritual side of the ninja world more. He may start to understand the deeper meaning behind the ninja code and how it relates to the balance of nature, which in turn makes him a more well - rounded and respected ninja.
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.
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.
Naruto might become more cautious. Losing an arm would make him realize his vulnerability more. He would probably be more strategic in battles, relying less on brute force and more on his intelligence and remaining ninja skills.
Naruto's character would likely become more self - reliant. Without a mother figure, he'd have to learn to take care of himself from a young age. This could make him more independent in his decision - making and less likely to rely on others for emotional support.
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.
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.
Naruto would likely become more distrustful at first. He's always been so open and trusting of his friends, so this betrayal would shatter that. He might become more withdrawn, constantly second - guessing people's motives.
Naruto would likely become more independent. Without his parents' attention, he would have to fend for himself more. He might grow up quicker and be more self - reliant. For example, he would have to learn to cook and clean for himself at a much younger age.
