It changes the plot in several ways. Firstly, Naruto's new power could make the Leaf Village seem even more powerful, which might attract more enemies or allies. Secondly, his relationships with other characters would be different. Since he can heal, people would rely on him more, like Sakura might not focus as much on her medical skills. And thirdly, it could change the way missions are carried out. With Naruto's healing powers, they could take on more dangerous missions knowing he can patch them up.
Imagine Naruto with all those alien fanfic powers. He could have the power of super strength like some hulking alien species, or the ability to turn invisible like certain stealthy aliens. His combat style would be a wild mix of ninja techniques and alien powers. He could shoot energy beams from his hands or teleport across long distances without using ninja techniques. This would make him a force to be reckoned with not only in his own world but potentially across the universe in a much broader sense.
In this fanfiction, the prototype powers could be something like an early form of chakra manipulation that is different from the traditional Naruto world's chakra use. It might be more raw and unrefined, with the potential for new and unique jutsu.
His hidden powers might be the ability to control all five basic nature types without any training. In the original story, Naruto had to work hard to master different nature types. But in a fanfiction, it could be that he has this innate ability which was hidden all along. This would make him extremely powerful and feared by his enemies.
In some fanfictions, Naruto's multiverse powers are portrayed as a way to bring together different versions of himself. Each version has its own set of skills and knowledge. By merging these aspects, he becomes an even more powerful and complex character, able to solve problems that were previously insurmountable.
One possible new power could be the power to absorb and use any chakra, regardless of its origin. This would make him extremely powerful as he could draw from the chakra of his enemies or even from natural sources like the sun or the earth. He could also gain the power of telepathy on a large scale, being able to communicate with anyone in the world or even across different dimensions. Additionally, he might obtain the power of instant teleportation to any place he desires, which would give him a huge advantage in battles and travels.
Well, he could use Freddy's power of entering people's dreams to fight his opponents in the dream realm. Maybe he would trap his enemies in a never - ending nightmare, causing them mental distress and weakening their will to fight in the real world.
In a Naruto - Superman powers fanfic, perhaps Naruto gets some of Superman's powers accidentally. He struggles to control the new powers like heat vision and super speed along with his own ninja abilities. Superman, on the other hand, discovers he can use chakra in a limited way and they both have to figure out how to use these new combinations of powers effectively.
Perhaps he has the power of elemental control. So, he can manipulate fire, water, air and earth. For example, he could use fire to create barriers or water to douse dark magic attacks. It makes the story more exciting as he has new ways to fight against evil forces.
I recommend "Doomsday: Healing Female Supporting Character". The female protagonist of this book has the healing ability of water. In the apocalypse, she fought together with her teammates and became comrades who could die together. This book was full of healing elements, and there were cute pets. The plot was relaxed and cheerful, very suitable for readers who wanted to relieve stress. I hope you like my recommendation. Muah ~
