In such a fanfiction, it could be possible through a dark corruption of Naruto's power. Maybe the Nine - Tails' influence takes over him completely. His powers could go out of control, and with his incredible strength, he might start attacking without restraint, believing that the current world is beyond saving or redemption.
It could be due to a prophecy misinterpretation. Suppose there is a prophecy that Naruto misinterprets as the Leaf Village needing to be destroyed for the greater good. Or perhaps he is tricked by a very cunning enemy who convinces him that the Leaf Village is the root of all the problems in the ninja world.
First off, you need a compelling reason for the world to be destroyed. It could be a natural disaster on a massive scale or a villain with a diabolical plan. Develop characters that have different goals and motivations in the face of this crisis. Also, think about the setting and how it changes as the destruction progresses.
Well, in a fanfiction context, it could be possible if we consider a crossover universe where Naruto somehow ends up in the Star Wars galaxy. Maybe he's brainwashed by the dark side's influence which is similar to some dark forces in his own world. This could lead him to betray the Jedi ideals that he might have adopted during his time there.
In this fanfic, it could be that the power of Olympus has become corrupt. Percy, being a hero with a strong sense of justice, decides that the only way to set things right is to destroy it and start anew. He could first target the symbols of the gods' power, like Zeus' lightning bolt. With the help of his friends from Camp Half - Blood, he might stage a full - scale assault on Olympus, using their combined skills and powers to take on the gods and their defenses.
One possible reason could be a dark turn in his character. Maybe he's been corrupted by some external force like a powerful and evil magic. Another reason might be a misunderstanding. For example, he believes the camp has betrayed him in some way, so he lashes out in anger.
Yes, I recommend novels such as "The Source of the World","The Doomsday Superhero System", and "I Create the Doomsday". They were all novels where the male protagonist wanted to destroy or save the world. I hope you like this fairy's recommendation. Muah ~😗
Well, in fanfiction, anything can be possible. Maybe it could be through some sort of multiverse or magical crossover event. A wizard or a powerful being could have messed with the fabric of reality and made Naruto the son of Thor. It's a wild concept but that's the beauty of fanfiction, it allows for such out - of - the - box ideas.
In a fanfiction where Naruto becomes like Itachi, it could be due to intense training. Naruto might study Itachi's fighting techniques, like his use of the Sharingan-based moves. He could also adopt Itachi's calm and collected demeanor, which is very different from his usual energetic self. For example, he may start to think more strategically in battles, just as Itachi did.
Perhaps a powerful villain has the ability to combine different powers from different universes. This villain targets Naruto and in the process of fighting against this threat, Naruto somehow absorbs the knowledge of the Kamehameha. He then has to figure out how to use it in his own ninja - style way.
Yes, it's possible. One way to write it could be that Naruto meets a character from another universe who knows Hadouken. This character could be a time - traveling Street Fighter expert. Naruto, being the eager learner he is, would be fascinated by this new powerful move. He would start training with this newfound friend, first learning the basic stances and the energy - gathering techniques required for Hadouken.
