Well, it could be about a dark version of Naruto having the power or the need to consume souls. Maybe it's a twisted take on his character where he's no longer the hero we know, but a being driven by some dark force to feed on souls for power or survival.
It could be comical. Just the idea of Toothless trying to eat Hiccup is absurd considering their strong bond in the normal storyline. It would be like a cat suddenly trying to eat its owner in a really silly way.
Obviously Naruto himself would be a main character, in his dark form. There might also be other characters like Sasuke. Sasuke might be in a position of either trying to stop Naruto or joining him in his dark deeds. And Sakura could also be there, perhaps as a voice of reason trying to bring Naruto back from the darkness.
In some 'dark luffy fanfiction', Luffy could be possessed by an evil entity. This entity twists his mind and makes him see his friends as enemies. So, he begins to attack the people he once cared for deeply. The crew has to find a way to save Luffy from this dark influence without hurting him, which creates a lot of tension and drama.
One interesting concept could be a darker version of Luffy's leadership. Instead of his usual carefree and positive leadership, it might show a more calculating and perhaps even ruthless side in making decisions for the crew's survival in extremely tough situations.
Some dedicated One Piece fan forums might also be a good place to look for 'dark luffy fanfiction'. Members often share their own works or recommend stories they've read.

Well, if Harry ate a devil fruit in fanfiction, he might gain some extraordinary powers. For example, if it was a Logia - type devil fruit, he could transform into an element like fire or water. This would completely change his abilities and how he interacts with the world around him. He could use these new powers to fight against his enemies in a whole new way.
The main difference is in Luffy's character. In the original, he is all about friendship, freedom and having fun. But in the 'luffy dark side fanfiction', he may be more self - centered and less concerned about the well - being of others.
Well, if Naruto ate a Logia Devil Fruit in fanfiction, he would likely gain some amazing new powers. Logia fruits often give the ability to transform into an element. Naruto could potentially combine his existing ninja skills with the power of the Logia fruit. For example, if it was a fire - based Logia fruit, he could use his Rasengan and infuse it with the power of fire from the fruit, making it an even more powerful attack.
He might gain an enormous boost in his chakra reserves. This could make his jutsus much more powerful and enable him to perform complex techniques with ease.
