In some fanfictions, Luffy's Devil Fruit is indeed considered the strongest. His Gum - Gum Fruit gives him unique abilities like stretching his body in incredible ways. In fan - created stories, these abilities can be enhanced even further, making him almost unbeatable.
😋I recommend the following novels to you:
1. " My Trash Fruit ": The protagonist has the ability of the Devil's Fruit to abolish everything and is determined to become the most awesome leader.
2. " I Abandoned the Magical Beast Seed, Creating the Mythological Era ": The protagonist travels through the foreign world and has the ability of the Demon Fruit. Together with the gods and devils behind him, he creates a mythological world.
3. " Top Grade Demon Fruit System ": The protagonist's pig trotter soul transmigrated to another world, possessing the heaven-defying Demon Fruit System, farming, leveling up, face-slapping, and posturing.
4. " Devil's Fruit Merchant ": The protagonist becomes a devil's fruit merchant, supplying the fruits that the gods like.
5. [The Devil's Fruit in the American Manga: The main character only wants to eat all the Devil's Fruit in the American Manga world. There is no enemy that the Devil's Fruit cannot defeat!]
The above novels are full of fantasy, and the demon fruit is an important element. I hope you will like my recommendation.
Imagine Luffy ate a devil fruit that gave him the power to control minds. This would be a very different power compared to his current Gum - Gum abilities. His crew would have to trust him completely not to abuse this power. There could be ethical discussions within the crew. Also, in terms of leadership, Luffy might have an easier time getting others to follow his plans, but it could also create some tension if the crew felt he was relying too much on his mind - control powers instead of his natural leadership qualities.
The Fire Devil Fruit could make Naruto more confident. Having such a powerful ability would give him an edge in battles and make him feel more capable. This newfound confidence could also change how he interacts with his friends and allies. He might be more assertive in leading them.
I recommend the two novels, One Piece: I'm a Big Boss and Naruto: The Demon's Law, to you. The main character of One Piece I Am a Big Boss became the West Ocean mafia in the world of One Piece. He ate the fruit of the Demon's Eye and became the world's big boss. Meanwhile, the main character of Naruto Demon Law, Medicine Master Yu, awakened the Demon Fruit in Naruto World, and the human puppets he created also had the ability of the Demon Fruit. I hope you like my recommendation.
If Luffy ate a different devil fruit, his entire power set and character would change drastically. For example, if he ate a Logia type like the Smoke - Smoke Fruit, his fighting style would be more about evasion and stealth. He could turn into smoke to avoid attacks, and his stretching abilities would be gone. His crew might also have to adjust their battle strategies around his new powers.
If Naruto ate a Paramecia Devil Fruit, his physical abilities might change drastically. For example, if it was a rubber - like Paramecia fruit, his already acrobatic fighting style could become even more so. He could stretch his limbs to attack from unexpected angles, much like Luffy in One Piece. This would give him an edge in close - combat situations, and his opponents would have a hard time predicting his moves.
If Naruto had the Fire Devil Fruit, his combat style would change drastically. He could combine his existing ninja skills with the power of the fruit. For example, he might be able to infuse his Rasengan with fire, making it even more powerful. Also, his mobility could be enhanced as he could use fire to propel himself in new ways. This would make him a more formidable opponent in battles against strong foes like Sasuke or Pain.
One of the main things that make it strong in fanfiction is the creative use of its basic properties. Writers can make Luffy use his stretching in ways that are not shown in the original manga or anime. He could stretch his internal organs to survive otherwise fatal blows. Or he could use his stretched body to create complex structures for defense or to launch multi - directional attacks. This freedom of creativity in fanfiction enhances the perceived strength of his Devil Fruit.
