Well, Naruto might develop the ability to use his shadow clones in new ways with Superman's powers. Since he's so strong and fast now, his clones could be used to perform complex maneuvers that were previously impossible. Also, he could develop a new form of sensing ability. Just as Superman can sense danger from afar, Naruto could combine that with his own natural sensing skills to detect threats even more accurately, not just in the physical world but also in the spiritual and chakra - related aspects.
In this fanfiction, Naruto could develop the ability to transfer Superman's powers to others temporarily. He's always been about sharing and teamwork. So, he could give his friends a boost of super - strength or flight for a short time. Another new ability could be using his Superman - like powers to travel between different dimensions. He already has some experience with other - worldly places in the Naruto universe, and with these new powers, he could explore even more, and maybe even bring back new knowledge or powers from those dimensions to help his village and the ninja world.
He could develop the ability to combine his chakra with Superman's powers. For example, he might be able to use his Rasengan while flying at super - speed. Or he could infuse his chakra into his heat vision to make it even more powerful.
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.
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.
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.
He could develop a 'Flash - Clone Jutsu'. He'd use his super - speed to create clones that are almost indistinguishable from his real self due to the speed at which they are created. Another technique could be 'Speed - Healing'. Since the Flash has a fast metabolism which aids in healing, Naruto could develop a similar ability where his wounds heal much faster when he uses his speed chakra.
Well, it could be something like the ability to control elements in a completely new way. For example, instead of just the basic five elements in Naruto, the new bloodline might allow for the manipulation of light or dark energy. Maybe it gives the power to teleport short distances instantly, which would be a huge advantage in battles.
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.
He might gain some of Madara's Sharingan - related abilities. Maybe he could use some of the advanced genjutsu techniques that Madara was proficient in. Since Madara had strong chakra, Naruto could also potentially have an increase in his own chakra levels or a new way to manipulate chakra, like Madara's ability to control the Susanoo.
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.
Another ability Naruto could develop is enhanced stealth. Itachi is known for his stealth and ability to move undetected. During the three - year training, Itachi could teach Naruto how to move more quietly, hide his chakra signature better, and approach opponents without being noticed. This would give Naruto an edge in combat, especially when facing more powerful opponents where a surprise attack could be crucial.
