Well, he'd probably be super powerful. The Tenseigan gives amazing abilities like enhanced strength and unique ocular jutsu. Naruto already has his own strong chakra and skills, so with the Tenseigan, he could take on much tougher enemies. Maybe he could even use it to bring more peace to the ninja world in the fanfic.
In a fanfic where Naruto has the Tenseigan, it would open up a whole new world of possibilities. First, his sensory abilities would be off the charts. He could detect enemies from much further away. Second, the Tenseigan - based attacks he could create would be formidable. For example, he could fire energy blasts with incredible precision. Also, his understanding of the ninja world's secrets might deepen, as the Tenseigan often comes with knowledge related to the Otsutsuki clan. This could lead him to discover new ways to protect his village and friends.
If Naruto had the Tenseigan in fanfic, it would change his fighting style completely. He'd no longer rely solely on his Nine - Tails chakra and Rasengan - like techniques. With the Tenseigan's power, he might be able to control gravity or manipulate energy in ways he couldn't before. It would also make his enemies more cautious of him, and he'd likely be a key figure in any major conflicts in the story.
If Naruto had the Tenseigan in fanfiction, he would likely become extremely powerful. His combat abilities would be enhanced, as the Tenseigan gives access to powerful jutsu. He could also gain new ways to sense chakra and enemies, making him even better at tracking and anticipating attacks.
Well, he would probably become extremely powerful. The Tenseigan has some amazing abilities, so Naruto could use it to enhance his already formidable skills like his Rasengan and his Sage Mode. He might be able to take on even stronger enemies with ease.
If Naruto had the Sharingan in fanfic, he'd likely become even more powerful. His combat skills would improve as he could use the Sharingan to predict his opponents' moves more accurately. He might also be able to use some of the unique jutsus associated with the Sharingan. For example, he could potentially learn to use Amaterasu if the fanfic writer allows for that kind of power combination.
He would likely become even more powerful. The Sparda is a very powerful weapon/entity in its own right, so combined with Naruto's skills, he could be nearly unstoppable.
In a fanfic, Naruto with the Rinnegan and Sharingan would have a whole new set of challenges. He would have to deal with the jealousy and fear of other ninja villages. His own village might also be divided on how to handle his new powers. On the positive side, he could use these eyes to better understand the history of the ninja world. For example, the Rinnegan might give him insights into the Sage of Six Paths' true intentions, and the Sharingan could help him uncover secrets about his own family. He would also have to train hard to fully utilize the combined potential of these two powerful eyes, which could lead to some interesting training arcs in the fanfic.
He would probably become an even more formidable fighter. The Blades of Chaos could add a new dimension to his combat style, allowing him to perform more acrobatic and powerful attacks.
Well, he could use the power to control plants during battles. He might be able to create thick vines to trap his enemies or make plants grow rapidly to block attacks. It would add a whole new dimension to his combat abilities.
His character would likely become more complex. With the Tenseigan's power, he would face new challenges and responsibilities.
If Naruto had Yang's weapons in a RWBY fanfic, it would change the dynamics of battles. Naruto's chakra could give a new edge to the weapons. He might also modify the weapons a bit using his ninja knowledge. For example, he could find a way to attach some of his ninja tools to the gauntlets. And his fighting style would mix the brute force of Yang's attacks with his own ninja agility.
He could gain new stealth abilities. Kikaichu are known for their ability to be discreet, so Naruto might be able to spy on enemies more effectively.
