Yes, definitely. They offer additional stories and perspectives that you might not get from the anime or manga alone. For example, they might explore the backstories of some minor characters in more detail.
Yes, it is quite common. 'One Piece' has a huge and passionate fan base. Fanfiction allows fans to explore their creativity and their love for the series in different ways. They can create new adventures for the Straw Hat crew, or explore different relationships between characters. So, a lot of 'One Piece' fans enjoy reading fanfiction to get more of the 'One Piece' world that they love.
In a fanfiction where Naruto is a fishman in One Piece, Naruto would face new challenges. For example, dealing with the discrimination that some fishmen face in the One Piece world. But he'd also have new opportunities. He could use his fishman physiology to swim faster and deeper, discover hidden treasures, and maybe even find a way to connect the ninja world with the pirate world. His Nine - Tailed Fox chakra might also have some interesting interactions with the strange powers in One Piece.
The unique aspect is that it combines the familiar characters of One Piece with the concept of reaction. It's fun to see how characters like Luffy or Zoro would react to things they might not have known before, like modern technology or different interpretations of their own stories.
Some fans might like it. They could see it as a way to show Naruto's strict parenting side and how he is trying to instill good values in Boruto. It would add a new dimension to their relationship.
Some fans would be very disappointed. Naruto is a character that represents hope and friendship in the original series. So seeing him die alone in a fanfiction goes against the positive themes of the original. They might not like this dark take on the character.
There would be a lot of mixed reactions. Some hardcore fans who have dedicated a lot of time to writing Naruto fanfiction might feel betrayed. On the other hand, there are those who are more focused on the official Naruto products like the anime, manga, and games, and might not be as affected. However, overall, it would create a stir in the Naruto fan community and lead to a lot of discussions and debates.
Some fans might express their disapproval in a civilized way, like leaving comments on the relevant platforms explaining why they think it's a wrong portrayal. But at the same time, others may accept it as a form of creative freedom within the fanfiction world, as long as it's clearly labeled as an alternate and non - canonical view.
Some fans would be extremely shocked and angry. Kushina is a beloved character, and Naruto slapping her goes against the loving relationship they should have as mother and son. They might feel that it's a disrespect to the original story's characters and themes.
