He could have the ability to perform kido, which are the spells used by Soul Reapers. This would give him a whole new range of offensive and defensive capabilities. He might also be able to use bankai, a super - powerful form of his zanpakuto. His new powers could include enhanced spiritual perception, allowing him to sense things that normal ninjas can't, like the presence of Hollows or spiritual disturbances.
One of the new abilities Naruto could have with Soul Reaper powers is the use of shikai. This would transform his zanpakuto into a more powerful form with unique abilities. For example, it could have the power to control the elements in a different way than his normal ninja skills. He could also have the ability to traverse between the living world and the Soul Society, which would open up a whole new realm of adventures. His Soul Reaper powers could also give him the ability to heal spiritual wounds, which could be useful when dealing with cursed techniques or dark chakra in the Naruto universe.
Naruto with Soul Reaper powers could have the power of reiatsu manipulation. He could use his reiatsu to intimidate opponents or strengthen his attacks. Another ability could be the use of soul burial, which is a way to send lost souls to the Soul Society. This could be a very interesting addition to his character as he already has a strong sense of justice and helping others. Also, he might be able to communicate with spirits more easily, which could lead to him getting advice or knowledge from the other side.
He could have the ability to use Sonido, which is a high - speed movement technique in the Arrancar world. This would make him much faster than normal ninjas. Also, his zanpakuto could have unique abilities, like the ability to cut through space - time, which would be a huge advantage in battles.
Naruto might gain the ability to tap into a primal energy within him due to his wrath powers. This energy could allow him to heal faster when injured in battle. Also, he could have the power to influence the emotions of his enemies. When they look into his eyes during his wrath - filled moments, they could be filled with fear or hesitation. Additionally, his physical attacks could carry a sort of 'wrath - curse' that weakens his opponents over time as they are continuously exposed to his wrath - powered strikes.
One new ability could be ice - skating at super - speeds. He could glide across water or land, using his ice - skates made of pure ice, and quickly reach his destination or dodge attacks. It would be like a combination of his natural athleticism and his new ice powers.
One new ability could be the power to charge his own body with kinetic energy for enhanced physical attacks. He could deliver punches or kicks that explode on contact, similar to Gambit's charged staff strikes. Another ability would be to create energy barriers by rapidly charging the air around him. This would be a great defensive move, something Naruto currently lacks in his regular skill set. He could also potentially use Gambit's power to sense the energy levels of his enemies from a distance, giving him an advantage in strategizing his attacks.
Another ability could be dark energy projection. Naruto could project bolts of dark energy from his hands or body. This energy could be used to blast away enemies or even to corrupt other things it touches, like sealing jutsu or barriers. It would be a very different and more sinister form of attack compared to his normal Rasengan.
Well, Naruto could gain the ability to heal in a more advanced way. Just as the avatar can sometimes use their connection to the elements to heal, Naruto might be able to do the same with his chakra. He could also have the power to merge with the natural world around him, similar to how the avatar can connect with nature. This would give him an edge in stealth and surprise attacks. Plus, he could develop a new form of sensing, being able to detect not just chakra but also the energy of the elements around him.
One new ability could be the power to heal quickly like some mutants. This would make him even more resilient in battles. He could also have the power to sense danger from a much greater distance. And perhaps he could have the ability to fly, not just by swinging on webs but by using some sort of mutant - based flight power. This would change the way he moves around the city and approaches crime - fighting.
Naruto would gain some really cool (pun intended) new abilities. The ice - making ability would be the most prominent. He could form ice clones, similar to his shadow clones but with the added advantage of being made of ice and potentially having more durability. His sensory abilities might also be enhanced, as Esdeath has a good sense of her surroundings when using her powers. He could detect enemies hidden in the ice or snow. And, like I said before, the time - freezing power. This would allow him to analyze his opponents' moves during the frozen time and come up with the perfect counter - attack. It would add a whole new dimension to his combat skills.
In this fanfiction, Naruto could potentially develop the ability to create dark energy constructs like Raven does. For example, he could form weapons out of this energy, giving him an extra edge in close - combat situations. He may also inherit Raven's power of flight, which would completely change his mobility in battles and how he approaches combat scenarios. Additionally, Naruto could gain the power to absorb and redistribute energy, which could be used to either heal himself or boost his attacks. This new set of abilities would not only make Naruto more powerful but also open up new storylines and character developments within the fanfiction.
He could develop the ability to combine his chakra with his Spider - Man powers. For example, he could infuse his webs with chakra to make them stronger or even give them different properties like being able to cut through objects. Another new ability could be using his shadow clones in combination with his Spider - Man agility. He could send clones to different locations while swinging around with his webs, creating a more complex battle strategy.
