What are the coolest applications of Naruto's multiverse powers in fanfiction?
One cool application is that Naruto can use his multiverse powers to change the fates of his friends. For example, if Sasuke died in his own universe, he could use these powers to find a universe where Sasuke is alive and bring that Sasuke to his world. Another cool thing is he can learn new jutsu from different universes. Maybe in one universe, there's a super - powerful fire - style jutsu that he can bring back and use in his own world.
In fanfiction, the coolest application of Naruto's multiverse powers could be to rewrite the entire ninja history. He could go back to the very beginning of the ninja world in different universes and change things like the origin of the tailed beasts or the formation of the hidden villages. This would have a huge impact on his own universe. He could also use these powers to communicate with long - dead ninja legends from other universes, getting their wisdom and using it to better his own skills and the state of his world.
Well, in fanfiction, Naruto might use his multiverse powers to prevent disasters. Say there's a prophecy in his universe about a great cataclysm. He could use his powers to jump to other universes and find out how they averted a similar disaster. Then he could bring back that knowledge or even enlist the help of powerful beings from those universes. Also, he could use these powers to create a sort of 'ninja utopia' by gathering the best aspects of different ninja worlds. He could take the peaceful nature of one universe, the advanced technology of another, and combine them in his own world.
