He could eat the Pika Pika no Mi (Glint - Glint Fruit) which gives the power of light, allowing him to move at the speed of light and create powerful light - based attacks. And perhaps the Yami Yami no Mi (Darkness - Darkness Fruit) which can absorb other attacks and create a gravitational pull. Combining the powers of light and darkness would be quite a unique and powerful combination for Naruto in this fanfiction.
Well, he might gain new powers which could make him more confident. For example, if one of the devil fruits gives him the power of flight, he would feel more powerful and it could change his approach to battles. He might become a bit more adventurous too, as he explores the limits of his new abilities.
One potential combination could be if Naruto ate the Ope - Ope Fruit (giving surgical - like powers) and the Inu - Inu Fruit (Dog). He could use the Ope - Ope powers to manipulate his body parts while in his Dog form, perhaps making his attacks more precise or his defenses stronger. This would also open up a whole new set of strategies for him in battles. It's all about how the fanfiction author would choose to blend these very different power sets and how Naruto would learn to use them effectively.
Another fanfiction concept could involve Naruto being sent to the One Piece world through some kind of strange ninja jutsu gone wrong. There, he eats a Logia Devil Fruit that allows him to turn into water. He teams up with the Straw Hat Pirates and uses his water - based powers, along with his ninja knowledge of chakra control, to help them in their adventures. For example, he could use his water form to put out fires on the ship or create water - based defenses against enemies.
In most One Piece canon, a person can't eat multiple devil fruits due to the risk of exploding. However, in fanfiction, the rules can be bent. Some fanfictions might allow Luffy to eat multiple devil fruits by creating special circumstances or new powers that counteract the normal limitations. For example, a fanfiction could introduce a powerful magic or a unique ability that enables Luffy to safely consume and control the powers of more than one devil fruit.
In the Naruto universe, Devil Fruits are from One Piece, and Naruto's world has its own power system like chakra. So, it's highly unlikely in the original Naruto story. However, in fanfiction, anything can happen. The author might create some kind of crossover logic to make it possible, like a strange portal connecting the two universes.
The powers of devil fruits can be integrated by having characters discover them in a strange new land that has a connection to both the Naruto and One Piece universes. For example, a portal could open up and Naruto and his friends find a devil fruit tree. They then have to figure out how these new powers work within the context of their own ninja abilities. Maybe the devil fruit powers can be combined with chakra to create even more powerful attacks.
Devil Fruits would make the Chunin Exams far more unpredictable. Some characters could suddenly have powers like flight or super strength. This would disrupt the normal balance of power among the genin. For instance, a character with a Zoan - type Devil Fruit could transform into a powerful beast, giving them an advantage in combat.
Another idea is a Devil Fruit that gives Luffy the ability to transform into different animals. He could turn into a powerful eagle to fly over islands and scout for danger or transform into a strong bear to have enhanced strength and endurance in close - combat battles. This would change his fighting style completely and make for some really interesting interactions with his crew and opponents.
The cultural clash is really interesting too. Naruto comes from a world with a very different culture compared to the DxD world. Adding Devil Fruits into the mix makes it even more complex. For instance, Naruto's values of loyalty and hard work might interact in unexpected ways with the more morally ambiguous elements of the DxD world and the power - hungry nature often associated with Devil Fruit users.
