Well, it's not a very common or traditional concept in the One Piece fandom. Luffy is the son of Dragon in the original story. But in the world of fanfiction, some people might explore this idea for the shock value or to create a really different take on the characters and the story's dynamics. However, it would require a lot of creative liberties to make it work within the existing One Piece lore.
In a 'Luffy son of Kaido' fanfiction, the plot could be full of twists. Luffy could start off as a more aggressive character due to Kaido's influence, but gradually find his true self as he spends time with the Straw Hats. There could be a plot where Kaido tries to use Luffy for his own ends, perhaps to take over the Grand Line. The other Yonko might also get involved, seeing Luffy as a potential threat or an opportunity. Luffy's friends would have to deal with the fact that he is related to Kaido, which could cause some rifts in the crew. And as Luffy discovers more about his heritage, he might have to make some difficult choices between loyalty to his friends and his new - found family ties. It could also explore how the world of One Piece would react to the news that Luffy, the up - and - coming pirate hero, is the son of one of the most feared pirates in the world.
In 'luffy vs kaido fanfiction', Luffy's growth and new abilities are often explored. He might develop new forms of his Gear powers to face Kaido. Kaido, being extremely powerful, forces Luffy to push his limits. Fanfictions may also focus on the intense battle scenes, with detailed descriptions of their attacks and counter - attacks.
