In the fanfiction, if Naruto finds a devil fruit, it could lead to some interesting alliances. Maybe he would team up with some characters who are interested in this new and strange power source. For example, Sasuke might be both intrigued and a bit jealous, which could create a whole new dynamic between them. Also, the Akatsuki might try to steal the power from Naruto, leading to a series of intense battles.
There could be a powerful pirate. In many fanfictions, pirates are always on the lookout for devil fruits to gain more power. A well - known pirate captain might hear about Harry having the fruit and send his crew to steal it. They might use force or trickery to get it from him.
If Naruto ate a Paramecia Devil Fruit, his physical abilities might change drastically. For example, if it was a rubber - like Paramecia fruit, his already acrobatic fighting style could become even more so. He could stretch his limbs to attack from unexpected angles, much like Luffy in One Piece. This would give him an edge in close - combat situations, and his opponents would have a hard time predicting his moves.
If Naruto had the Fire Devil Fruit, his combat style would change drastically. He could combine his existing ninja skills with the power of the fruit. For example, he might be able to infuse his Rasengan with fire, making it even more powerful. Also, his mobility could be enhanced as he could use fire to propel himself in new ways. This would make him a more formidable opponent in battles against strong foes like Sasuke or Pain.
He could end up selling the devil fruit. In some fanfictions, devil fruits are extremely valuable and sought - after items. Harry might not want the power or the responsibility that comes with it, so he decides to cash in on it. But this could also attract all kinds of unwanted attention from powerful and dangerous characters who want the fruit for themselves.
In Naruto fanfiction where Devil Fruits are involved in the Chunin Exams, it could lead to some really interesting scenarios. For example, a character might eat a Devil Fruit and gain unique powers that completely change the dynamics of the exams. They could use abilities like Luffy's stretchiness from the Gomu Gomu no Mi to reach far - off targets or avoid attacks in a creative way.
In a Konoha fanfiction where Naruto has a Logia Devil Fruit, he could have amazing new powers. For example, if it was a fire - based Logia fruit, his Fire Style jutsu could be enhanced to a whole new level. He might be able to transform his body into fire completely, making it difficult for enemies to land a hit on him. Also, this new power could change the power dynamics in Konoha, as he would be even more formidable against threats both inside and outside the village.
One possible scenario in this fanfiction could be Naruto obtaining the ice devil fruit. This would completely change his combat style. He could use ice attacks in combination with his existing ninja techniques. For example, he might freeze an opponent's feet with ice and then follow up with a Rasengan. It would also add a new element to his character development as he'd have to learn to control this new power.
The Fire Devil Fruit could make Naruto more confident. Having such a powerful ability would give him an edge in battles and make him feel more capable. This newfound confidence could also change how he interacts with his friends and allies. He might be more assertive in leading them.
One idea could be that Naruto somehow obtains a Dragon Devil Fruit. He then gains the abilities like flying, breathing fire or some other dragon - like powers. This would completely change the dynamics of his battles in the Naruto universe. He could use his newfound flight to gain a strategic advantage over his opponents and his fire - breathing could be a powerful offensive move.
