If Naruto becomes a demon in a fanfic, it could lead to a whole new set of adventures. He might be shunned by the village he once protected. However, this could also be an opportunity for him to discover a new side of his power. He could use his demonic powers for good, but first he would need to overcome the prejudice against him. His relationships with characters like Sasuke and Sakura would be put to the test as they might not trust him immediately.
If Naruto becomes the Demon of the Mist in fanfiction, he might start to lose his sense of self. The title 'Demon of the Mist' implies a certain level of malevolence and mystery that is quite different from Naruto's usual sunny disposition. His ninja way would be severely tested as he tries to balance the new, darker identity with his old values. Maybe he'd be forced to fight against his former allies who see him as a threat now. Also, his appearance could change to something more in line with the image of a demon, which would be a shock to those who know him well.
If Naruto becomes a ghoul in a fanfic, he could potentially use his new powers in unique ways. His ninja skills combined with ghoul abilities like kagune would make him a very formidable fighter. Maybe he'd try to find a way to survive without harming innocent people, like finding alternative food sources or using his powers only against bad guys.
Well, if Naruto goes evil in fanfic, it's a total game - changer. First, his relationships would crumble. Sakura and Sasuke would be devastated. His sensei like Kakashi would try to reason with him but probably fail. And his enemies would be thrilled. They could use his new - found 'evil' side to their advantage and cause more chaos in the ninja world.
In a fanfic scenario where Naruto becomes the Juubi, it's a game - changer. Firstly, his appearance would probably change significantly, maybe having some Juubi - like features. His speed, strength, and the range of his jutsu would increase exponentially. He could use the Juubi's power to heal the land that has been damaged by years of war. However, there would also be those who see him as a threat and try to stop him, believing that no one should possess such power. This would create a lot of conflict and drama in the fanfic.
Well, in a fanfic where Naruto becomes ruthless, the entire ninja world would be in chaos. He's a very important figure, and his change in personality would likely lead to different power dynamics. Villages might be more afraid of him, and he could start making decisions that are more self - centered rather than for the good of all. He might also use his powerful jutsu without much regard for the consequences, like his Rasengan or Sage Mode.
If Naruto becomes greedy in a fanfic, it could lead to a breakdown in his relationships. His friends might not recognize this new, greedy Naruto. For example, Sasuke could see this change as a betrayal of their ideals of friendship and rivalry. Naruto's greed might also make him a target. Enemies could use his greed against him, like dangling the promise of ultimate power in front of him to make him do their bidding.
In some fanfics, if Naruto becomes Kyuubi, he might gain incredible power. He could have enhanced physical abilities like super strength and speed. His appearance might also change, taking on more Kyuubi - like features. Maybe his eyes would turn red like the Kyuubi's, and he could have a more menacing aura. This transformation could make him a more feared and respected figure in the ninja world.
In a fanfic where Naruto becomes an assassin, he might use his ninja skills in a more stealthy and lethal way. His signature jutsus like the Rasengan could be modified for assassination purposes. For example, he could make it smaller and more concentrated to strike vital points precisely.
In a 'Naruto becomes the Batman' fanfic, Naruto might start adopting Batman's methods. He could become more stealthy and rely on his intelligence more. For example, he might use gadgets similar to Batman's utility belt, like smoke bombs or grappling hooks. Also, his approach to justice could change. Instead of his usual straightforward ninja battles, he might start planning more strategically, much like how Batman plans his crime - fighting operations in the dark alleys of Gotham.
If Harry becomes a Naruto fanfic, he might start trying out Naruto - style ninja techniques in the wizarding world. For example, he could attempt to use chakra - like magic to enhance his spellcasting speed or power. It would be a really interesting crossover concept.
