One possible plot could be that Naruto, with the power of the Flame - Flame Fruit, becomes even more powerful in combat. He could use the fire - based abilities of the fruit to enhance his existing jutsu, like adding a flaming element to his Rasengan. This would make him a more formidable opponent against enemies, especially those with water - based techniques.
One idea could be that Naruto somehow gains the power of the Flame - Flame Fruit. He could use it to create new and powerful jutsu, like combining the fire nature of the fruit with his own chakra to make a super - heated Rasengan. Another plot could involve Naruto using the fruit's power to protect Konoha from a new and powerful enemy that is immune to normal ninja attacks but vulnerable to the unique flames of the fruit.
In this fanfiction scenario, Naruto eating the chakra fruit could change the entire power dynamic in the Naruto universe. Since chakra is such a fundamental aspect of the world, the fruit could potentially give Naruto the power to rewrite the rules of chakra itself. He could share this new chakra knowledge with his friends and allies, like Sasuke and Sakura. This would make Team 7 an even more formidable force. Maybe Naruto could also use the power from the chakra fruit to heal some of the long - standing wounds in the ninja world, like the rift between the different hidden villages.
In fanfiction, if Luffy ate the Flame - Flame Fruit, he would gain the power of fire. His attacks could be infused with flames, making his Gum - Gum Pistol even more powerful. He could also use fire to defend himself, like creating a wall of flames around himself.
His relationship with his friends might change. They would see him as even more of a powerhouse. Some might be in awe of his new power, while others, like Sasuke, might feel a bit of rivalry. Naruto would also have to learn to control the power of the fruit, which could be a struggle at first. This journey of self - control would make him more mature and responsible. He'd understand the importance of not misusing such a powerful ability and would strive to use it for the good of Konoha and his friends.
In this fanfiction, Naruto's relationships would experience significant shifts. With his friends, they would initially be curious and a bit envious of his new power. However, as time goes on, they would learn to work with it. His relationship with the village elders might change too. They would likely be more cautious about Naruto, fearing the potential destruction that could come with his new, powerful ability. But Naruto, being Naruto, would strive to prove that he can use the Flame - Flame Fruit's power for the good of the village and its people, thus gradually earning their trust back and strengthening his bonds with them in the process.
Another consequence could be on the political side. In the Naruto world, power often has political implications. With the power from the Shinju fruit, Naruto could become a target for those who want to use his power for their own gain. On the other hand, he could also use this newfound strength to bring about a more unified ninja world. He might be able to impose new rules or treaties that would ensure long - term peace, but this could also lead to some resistance from the more traditional ninja clans who don't want to lose their autonomy.
Luffy's character would develop in several ways. With the Flame - Flame Fruit, he'd have to learn to control the fire element. This would require discipline, which is something he doesn't have much of in the beginning. As he masters the power, he'd grow more responsible. Also, his reputation among other pirates and in the world would change. He'd be seen as an even more dangerous and unpredictable foe, which would add to his allure as a pirate captain.
The 'naruto dragon of the darkness flame fanfiction' might be about a unique concept where the Naruto story is intertwined with a dragon having the power of dark flames. It could start with the discovery of this dragon. Maybe a young ninja stumbles upon it in a hidden place. Then, the story could unfold as the ninja tries to understand the dragon's powers and intentions. It could also involve other Naruto characters getting involved, like Sasuke being interested in the dragon's power for his own purposes, or Kakashi trying to protect the village from the potential danger of this new element in the Naruto universe.
One possible plot could be Finn and Flame Princess building their life together in the Land of Ooo. They might face challenges like dealing with old enemies who see their union as a threat. Finn could use his adventuring skills and Flame Princess's fiery powers to protect their new family.
Another idea is that the dying will flame represents Naruto's unfinished business. In the fanfiction, it could be that there's a threat to the Hidden Leaf Village that Naruto was aware of before his death. His dying will flame then becomes a guiding force for his friends and family to uncover the mystery and save the village. It might lead them to hidden secrets or new allies.
