Well, it might be that a Naruto fanfiction writer decides to give a Naruto character the Dark Dark Fruit ability. For example, Naruto himself could gain this power. This would completely change his fighting style. Instead of relying solely on his Rasengan and Sage Mode, he could use the Dark Dark Fruit's powers to absorb attacks or create a dark - matter - like substance to trap his enemies. It would be a really interesting twist on his character development.
There are also side characters in Dark Dark Fruit fanfiction that gain popularity. These could be characters who are friends or allies of the Dark Dark Fruit user. They might have unique abilities that complement the powers of the Dark Dark Fruit, and their relationships with the main character add depth to the story.
There might be a fanfiction where the Dark Dark Fruit is the key to unlocking a hidden realm in the story's universe. The protagonist, having the Dark Dark Fruit, embarks on a journey to explore this realm, encountering strange creatures and uncovering secrets along the way. In this fanfiction, the author could play with the concept of darkness as not just a power, but also a source of mystery and discovery.
The Dark Dark Fruit could enhance Luffy's physical strength in a different way. Instead of just relying on his rubber body, the fruit's power could give him a more menacing presence in battle. He could use the darkness to absorb attacks and then redirect that energy, making his counter - attacks even more powerful. For instance, if an enemy throws a punch, Luffy could use the dark power to suck in the force of the punch and then send it back double - strength.
I recommend One Piece: The Dark Age. The main character has the most ferocious ability in the world because he ate the Dark Fruit. Combined with your given requirements, it should meet the needs of the main character to have many different abilities. I hope you like this fairy's recommendation. Muah ~😗
One possibility is that the Dark Dark Fruit's appearance in Naruto fanfiction would lead to a re - evaluation of power structures. In the Naruto world, power is mainly determined by chakra levels and ninja skills. But with the Dark Dark Fruit, a new form of power is introduced. This could cause some characters to feel threatened, while others might see it as an opportunity to gain an edge. For instance, the Akatsuki might try to recruit the bearer of the Dark Dark Fruit to further their goals.
In such a fanfiction, perhaps Luffy's character would change drastically. The dark dark fruit might give him new powers like controlling shadows more intensely than Blackbeard. He could use it to create shadow clones of his crew for strategic battles, adding a new and darker dimension to his fighting style.
The World Government could become the main antagonist. They would see Luffy's new power as a threat, especially if he starts using it in ways that oppose their rule. They might send out their strongest agents, like the Admirals, to take Luffy down. The Admirals could have developed new techniques to deal with the dark dark fruit powers, making them a formidable foe for Luffy.
One interesting concept could be Luffy having to deal with the corrupting influence of the Dark Dark Fruit. Maybe he struggles to maintain his usual carefree and positive attitude while using its powers. For example, the power might make him more withdrawn at first as he tries to figure out how to control it without losing his sense of self.
