What are the Most Popular Fanfictions Where Naruto Knows Flying Raijin?

The plot could start with Naruto finding an old scroll that contains the secrets of Flying Raijin. He is excited but also a bit intimidated as it seems very complex. He begins to practice in secret, away from the village. As he practices, he discovers that he can use his own unique chakra nature to modify the jutsu slightly, making it more his own.

One of the most popular ones is 'Naruto: Magical Prodigy'. It has a high number of views and reviews. In this story, Naruto is born with magical abilities that are hidden until he reaches a certain age. Then he has to learn how to use them while still being a ninja. It's popular because it gives a fresh take on Naruto's character.

I really liked 'Flying Raijin: A New Era'. In this fanfic, a new character discovers a variation of the Flying Raijin. It's a short but exciting read that shows how the Naruto universe can be expanded with this iconic jutsu. It also has some great dialogue between the characters.

One possibility could be that Naruto has a really tough time at first. He might keep failing to perform the jutsu correctly. Maybe he tries to combine it with his Rasengan technique to create a new and more powerful move. For example, he could think of using the speed of Flying Raijin to quickly deliver a Rasengan to the enemy.

In many fanfictions, the Flying Raijin is often a key element in creating new plot twists. Since it allows for instant teleportation, it can disrupt the normal flow of a fight or a mission. A character might use it to infiltrate an enemy stronghold undetected or rescue someone from a seemingly impossible situation. This changes the direction of the story and keeps readers on their toes.

One great fanfiction could be 'Naruto: The Raijin Prodigy'. In this story, Naruto discovers a hidden scroll about the Flying Raijin early on. He spends countless hours practicing and eventually masters it in his own unique way. This changes the dynamics of many battles in the story.

One interesting plotline could be Naruto using the Raijin no Ken to defeat a powerful new enemy that the regular Naruto powers couldn't handle. Maybe it's an enemy from a different dimension who is immune to chakra but not to the unique abilities of the Raijin no Ken.

The fanfic 'Harry Potter and the Martial Arts Revolution' is quite popular. It features Harry introducing martial arts to the wizarding world, which causes a stir. People are both intrigued and a bit skeptical at first. Another popular one is 'Potter's Martial Arts Adventure', where Harry embarks on a journey that involves using martial arts to solve magical mysteries.

I'm not sure which specific fanfictions are the most popular with this concept. However, you can usually find some good ones on major fanfiction websites like Fanfiction.net or Archive of Our Own. Just search for 'Naruto is Minato's brother' in their search bars and sort by popularity or reviews.

The Raijin Sword in the fanfiction might have an ancient origin. It could be a weapon forged by a powerful ninja clan in the past. Maybe it was created to combat a great evil that once threatened the ninja world. And for some reason, it has now come into Naruto's possession.
