Were there any One Piece Doujinshi novels where the main character ate a bamboo demon fruit and partially turned into a bear, and was a brother of Luffy Ace?

😋I recommend you a Doujinshi novel called One Piece: Warcraft System, I Summon the Undead Army! The main character, Reg, had transmigrated to the Endless War Country, which was filled with souls. He had obtained the Monster Weapon Burst System, which allowed him to fuse with all kinds of demonic fruits! He could also summon the undead race and make them grow stronger. Conquering, plundering, conquering the sea, the sky, and the land, becoming the strongest existence! I hope you like my recommendation.😗

One Piece's demonic fruit ability users were Rolonoka Sauron and Nami respectively.

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.

😋I recommend the following Doujinshi novels to you, the main character must be Luffy: [Reborn in One Piece World: The story of the protagonist, Luffy, Ace, and Sabot becoming brothers and fighting hard for their beliefs in One Piece World.] "Starting from Luffy to save the world": A fledgling system, after being attacked by two bald heads, began to kill its host and merged into one. Luffy lost his rubber fruit and began a new life with the dream of saving the world. [One Piece: Super Pirates: Traversing the world of One Piece and becoming a supernova like Luffy is far from enough for Chen Feng, who owns a pirate group.] I hope you like this fairy's recommendation.

I recommend Two Doujinshi novels, One Piece: The Descent of the Flame Emperor and One Piece: The Flame Emperor Ace, to you. The main characters are both Ace. "The Descent of Emperor Yan" was the story of Ace's hard work in the pirate world after eating the Burning Fruit. In "The Descent of Emperor Yan," Ace had the Strange Fire system in Battle Break, which could effectively burn any enemy. I believe that you will enjoy reading both novels.(^^·)~ Stars.

I don't know of any novels about Chen Hua transmigrating to One Piece and eating the Thunder Fruit. However, if you are looking for such novels, I can recommend some websites such as Qidian Chinese Network, Xiaoxiang Academy, etc. You can search for similar novels on these websites and read them.

Hello, I'm a fan of online literature. According to my knowledge of online literature, the plot you mentioned is a novel called One Piece: Asura's Road. In this novel, the protagonist transmigrated to the world of One Piece and became a Shura with the empress. Shura were a type of human with powerful combat abilities. They could obtain great power by devouring the Demon Fruit.

The protagonist of One Piece had an Air Fruit that could materialize the air and summon a creature that could devour items-the phone bug. This phone bug could eat all kinds of materials, including metal, wood, and even seawater, and turn them into different powerful attacks. Therefore, One Piece might be a novel that met the requirements of the question. If you are interested in this novel, you can go and take a look. I hope you like this fairy's recommendation. Muah ~😗
