There were a few novels that were similar to Luffy's brother that he could recommend. Among them, One Piece: The Fruit of Rotation and One Piece World's Cultivation Journey are two novels recommended to you. The main character of One Piece: The Twirling Fruit was Luffy's subordinate. In the later stages, he was a BOSS, but he was not invincible. The main character in One Piece World was Luffy's brother. He became stronger step by step in One Piece and protected his brother. These two novels might meet your requirements for Brother Luffy.
Common themes in 'naruto luffy brother fanfiction' include power - sharing. Given their unique abilities, fans like to write about how they would teach each other or combine their powers. Also, friendship is a big theme. Even though they are brothers in these stories, their relationships with other characters from their respective worlds are still important, and the fanfictions often explore how they maintain those friendships while being brothers. And of course, there's the theme of family. The idea of them being brothers brings in a whole new family dynamic that wasn't present in the original stories.
Well, there is some 'naruto luffy brother fanfiction'. Some of them explore how their different powers would interact if they were brothers. For example, Naruto's ninjutsu and Luffy's Devil Fruit abilities could make for some really exciting adventures together. Also, the different worlds they come from, the Hidden Leaf Village and the Grand Line, could be combined in creative ways in these fanfictions.
They could go on an adventure to find a powerful treasure that combines the power of the One Piece and some kind of ninja - related artifact. Maybe they'd have to fight against a new enemy that is a combination of pirates and rogue ninjas. They might travel to new islands where Naruto's ninjutsu would be useful for exploring hidden caves, and Luffy's stretching ability would help them reach high places or cross large gaps.
Naruto might give Luffy training in stealth. Since Naruto is a ninja, he is well - versed in moving around unnoticed. Luffy, on the other hand, is more of a straightforward fighter. So Naruto could show him how to approach enemies without being detected first, which would be a new and useful skill for Luffy in his pirate adventures.
One common theme is family. Since it's about Luffy's brother OC, family bonds are often explored. The OC may have a different upbringing but still shares a deep connection with Luffy. Another theme is loyalty. The OC usually ends up being loyal to Luffy and his crew, just like the other Straw Hats.
In a Naruto - is - Luffy's - brother fanfiction, their relationship could be filled with a lot of chaos and fun. Given Naruto's love for ramen and Luffy's love for meat, mealtime would be quite an adventure. They both have a strong sense of justice. Naruto would understand Luffy's desire to become the Pirate King as he has his own goal of becoming Hokage. They'd share stories of their adventures, and Naruto could introduce Luffy to the concept of chakra, while Luffy would show Naruto the wonders of the Grand Line. Their bond would be unbreakable as they face challenges together.
I recommend "One Piece's Little Brother Save Me". The plot of this book is about the main character being a "vessel" and being hunted down by Lord Eam, the Void Throne. He uses the "Little Brother Save Me System" to become stronger. Although it was slightly different from the original novel, it was still very interesting. I hope you like this fairy's recommendation.
