In some Black Thunder One Piece fanfiction, there could be a story where the Straw Hats discover a hidden island during a thunderstorm.

As they explore, they have to deal with various traps and enemies that are also after the secrets of the island.
Well, often the main characters are still the Straw Hat crew. But in Black Thunder fanfiction, there might be some original characters added.

In some 'sakura in one piece fanfiction', Sakura could be a long - lost relative of a character in the One Piece world.

One interesting story could be about a pet seahorse that has the ability to predict storms in the One Piece world. It becomes a valuable asset to a pirate crew.

Well, there are fanfictions that delve into Ace's backstory more deeply. They might expand on his childhood, his relationship with his mother, and how he came to be who he was.

For instance, he could form an alliance with Blackbeard in a different context, which would lead to a whole new set of adventures and power dynamics.
One interesting 'One Piece Wano fanfiction' could be about a new character who is a master swordsman from Wano and teams up with Zoro.

There could be a story where a new character joins the Straw Hats and has a special ability that helps them in their journey, like being able to communicate with ancient sea creatures.
Well, there are fanfictions where the One Piece characters react to modern - day Earth things. For example, Luffy's reaction to a smartphone would be hilarious.

It creates really unique and fun crossovers.
There might be a 'ace one piece fanfiction' where Ace travels to a parallel world within the One Piece universe.
