Well, it would be really cool. Naruto could use his ghoul powers to sense other beings in a different way than with his normal ninja senses. His speed and strength would likely increase a great deal. In the story, he might start to struggle with the urge to feed on humans like a normal ghoul. This could create an internal conflict for him, which would add a new layer of depth to his character. And in battles, instead of just relying on Rasengan and other ninja techniques, he could use his ghoul abilities to surprise his enemies.
If Naruto had ghoul powers in fanfiction, it would change the story drastically. For one, his combat style would be very different. Ghoul powers involve using kagune, which are like weapons made from the ghoul's body. Naruto's usual ninjutsu and shadow clone jutsu would be combined with these new powers. He might be able to use his chakra to enhance his kagune attacks. Also, his relationship with his friends could change. Some might be afraid of his new, more monstrous side. And his role in the ninja world would shift as he'd have to hide his ghoul nature from those who would hunt him if they knew.
If Naruto had avatar powers in fanfiction, the storyline would be turned on its head. His character development would take a new direction. He could use the avatar state not just for fighting, but also for diplomatic purposes. Imagine him using the power to show unity among the villages. His power level would be off the charts, which means the power balance in the Naruto universe would be disrupted. This would lead to a reshuffling of alliances. Some characters might side with Naruto because of his newfound strength, while others might try to undermine him out of fear.
If Naruto had Superman's powers in fanfiction, it would change everything. His village would be almost invincible. With Superman - like powers, Naruto could fly around and keep an eye on all the hidden villages, preventing any surprise attacks. His super strength could be used to rebuild the village in no time after any destruction. Also, his x - ray vision could be used for various things like finding hidden traps or enemies. The power dynamic in the ninja world would shift completely, and Naruto would become an even greater legend.
If Naruto had Law Fruit powers in fanfiction, the story would change drastically. He could use the powers to create and enforce his own rules in battles. For example, he could nullify his opponents' jutsu by declaring it 'illegal' within his defined law area. This would give him a huge advantage and change the power dynamics in fights against strong foes like Sasuke or Pain.
If Naruto had Esdeath's powers, the plot would change drastically. Naruto's usual jutsu-based combat would be replaced by Esdeath's ice powers. His fights would be more one - sided as Esdeath's powers are extremely powerful. For example, in battles against Akatsuki members, he could freeze them instantly instead of engaging in long - drawn - out battles. Also, his relationships with his friends might change as his new powers could make some of them fear or envy him.
His relationship with his teachers would also be different. Iruka would be extremely proud but also a bit worried about Naruto getting too cocky with his powers. Kakashi, on the other hand, would be more focused on training Naruto to control and master these powers. Naruto's new powers could also attract the attention of other ninja villages. This would put pressure on his relationships with the people in his own village as they might see him as a potential target or a valuable asset. Some might be jealous, while others would be more eager to be his ally.
His friends in Konoha like Shikamaru and Kiba would see Naruto in a new light. They might rely on him more for protection, but also feel a bit of distance because of his elevated status. Naruto would have to work hard to maintain his old friendships and show them that he's still the same person deep down.
Well, if Naruto had Gambit's powers, his combat style would be drastically different. Gambit can charge objects with kinetic energy and make them explode on impact. Naruto could use this power in combination with his shadow clones. He could send clones with charged kunai or shuriken towards the enemy, creating a more explosive and unpredictable attack. This would give him an edge in battles, especially against stronger opponents like Pain or Madara. Also, Naruto's ability to adapt and strategize would be enhanced with this new power, as he could use Gambit's powers in creative ways to surprise his foes.
If Naruto had Quincy powers, his combat style would be drastically different. Quincy powers in 'Bleach' are mainly about manipulating spiritual energy in a very precise way. Naruto, who is used to his chakra-based techniques like Rasengan, would now have the ability to fire spiritual arrows or create constructs out of spiritual energy. This could potentially make him even more powerful in battles against the likes of Sasuke or the Akatsuki. His Sage Mode could also interact in interesting ways with the Quincy powers, perhaps enhancing the range and precision of his spiritual attacks.
His relationships would change a great deal. His friends might feel a bit overshadowed by his new power. For instance, Sasuke might feel even more compelled to compete with Naruto, but also realize the futility of it. His relationship with Sakura could become a bit strained as she might be in awe and a bit intimidated by him now.
Well, if Naruto had starfire powers in fanfiction, he could probably use it to enhance his existing jutsu. For example, his Rasengan might be infused with starfire energy, making it more powerful and having additional effects like burning or blinding opponents. Also, it could change his battle strategies as he'd have a new and different type of power to rely on.
