His powers would still be based on chakra, but he'd have to adapt them. His jutsus like the Fireball Jutsu could be modified to work with the elements in RWBY, like using Dust to enhance it. His Sage Mode would give him an even greater boost in combat against the Grimm.
If Naruto was reincarnated in RWBY, his powers would be a mix of his original ninja abilities and some new adaptations. His ability to create shadow clones would remain, but he might use them differently. For example, he could send clones to scout for Grimm in a wider area. His Rasengan would be a powerful close - combat move, and he could potentially combine it with RWBY - related elements, like infusing it with Dust energy. Also, his Nine - Tails chakra would make him extremely powerful, and he'd have to learn how to control it in this new world so as not to cause too much destruction.
Well, it could be really interesting. Naruto's skills and determination would make Jaune a much more powerful fighter. He might bring some of his ninja techniques to the RWBY world. For example, his Shadow Clone Jutsu could be used in battles or for training, just like how he did in the Naruto world. Also, his never - give - up attitude would inspire the other characters in RWBY.
He'd be extremely powerful. Accelerator's power of vector manipulation would give Naruto a whole new level of combat ability. He could deflect attacks with ease and launch powerful counter - attacks. His movement would also become more precise and unpredictable.
His powers would be a really interesting mix. Naruto's ability to use shadow clones could be on a whole new level. Instead of just creating a few dozen clones, he could create hundreds or even thousands like the Hulk can multiply his strength in some versions. And his Nine - Tails chakra might combine with the Hulk's rage - induced power. So when he's in his Hulk - like form, he would not only be physically strong but also have the added boost of the Nine - Tails' power, making him an almost unstoppable force. He could also potentially use the Hulk's jumping ability to traverse long distances quickly, which would be a new addition to his ninja - like mobility.
He might have a combination of his ninja powers and some sort of fire - based quirk from Endeavor. His Rasengan could be enhanced with fire, creating a really powerful and destructive attack.
His powers could be a mix of ninja skills and Thanos - like abilities. He might have enhanced physical strength similar to Thanos. His Rasengan could potentially be charged with some sort of energy related to the Infinity Stones. Also, his ability to sense chakra might be modified to sense other forms of power. Maybe he could even teleport like Thanos does in the comics, which would give him a huge advantage in combat.
He would likely have a combination of his existing ninja powers and Asgardian powers. So, he could still use his shadow clones, but also be able to summon lightning like Thor. Maybe he could even use his chakra to enhance his Asgardian abilities further.
He'd probably have some enhanced Sharingan abilities. Maybe he could awaken the Mangekyou Sharingan more easily and have unique powers associated with it. His chakra levels could also be different, perhaps even more powerful due to his Uchiha blood. He might also have an innate understanding of space - time ninjutsu like Madara did.
Naruto's powers would be a strange mix. He could inherit Orochimaru's ability to regenerate, but in a more Uzumaki - style way. His rasengan could be infused with snake venom or some sort of snake - based chakra. And he might be able to use Orochimaru's body - switching jutsu in a modified form, perhaps using it not for evil but for strategic purposes in battles.
The reincarnation of Naruto in RWBY fanfiction would have a profound impact on the plot. Naruto's experience with different types of combat and his knowledge of various jutsus would give him an edge. His presence could also disrupt the existing power balance in the RWBY universe. For instance, the academies in RWBY might start to incorporate some of Naruto's training methods. Moreover, Naruto's backstory of being an outcast and then rising to be a hero could inspire some of the characters in RWBY who are also facing their own challenges. His relationships with the other characters would be complex. He might initially be seen as an oddity but would gradually earn their respect through his actions.
If Naruto was the grandson of Madara and Tsunade in a fanfiction, his powers would be a unique combination. Tsunade's influence could give him the ability to create and manipulate chakra in a more efficient way for medical purposes. He might be able to heal not only physical wounds but also mental and chakra - related imbalances. From Madara, he could inherit the power to manipulate space - time, like Madara's use of the Rinnegan for teleportation. His Rasengan could then be used in conjunction with this space - time manipulation, allowing him to surprise his opponents. His power level would be off the charts, and he would need to learn to control these new abilities, which could be a central part of the fanfiction's plot.
