In addition to the Straw Hats, there could be new characters created specifically for this fanfiction. Maybe a powerful pirate captain who starts the holy war in pursuit of some great power. There might also be some important figures from the World Government side, like high - ranking admirals or Cipher Pol agents. And we can't forget about some of the old enemies of the Straw Hats who might team up with them or against them depending on the situation in this holy war scenario.
The Straw Hat Pirates would probably be the main characters. Luffy, with his determination and leadership, would be right in the middle of the action. Zoro, with his powerful swordsmanship, would be crucial in battles. Nami could use her knowledge of the weather to gain an advantage. And other members like Sanji, Usopp, and Chopper would also play important roles.
Obviously, Luffy would be one of the main characters. He's the captain of the Straw Hats and the central figure in the One Piece world. His actions and decisions would greatly influence any future scenarios.
It's hard to say for sure without reading it, but it could include the main characters from One Piece like Luffy, Zoro, and Nami. Maybe some new characters created by the fanfic writer as well.
The Straw Hat crew is bound to be central in the 'One Piece Enhancement Novel'. However, we might also see more of some supporting characters getting a spotlight. Maybe characters like Shanks, who has a deep connection to Luffy, could have more of their backstory explored or play a more significant role in the enhanced story.
Well, it could be about a war between different pirate crews over a powerful and holy artifact in the One Piece world. Maybe the Straw Hats get involved to stop the war and protect the balance of the Grand Line.
Tris and Four would likely still be main characters. Their relationship has been a central part of the Divergent series, and in a post - war scenario, they would be key in leading the rebuilding efforts or in bringing about change.
Sasuke could also be a main character. His power and his complex relationship with Naruto would play a role. He might have his own reasons for wanting to either defeat or control the Beast of War, perhaps related to his quest for power or revenge. And Sakura, with her medical ninjutsu skills and her growth as a fighter, could be crucial in treating the wounded during the battles against the beast. She might also have some unique insights into the nature of the beast based on her studies.
It's also possible that civilians who get caught up in the war in a significant way could be main characters. For example, a scientist who discovers something that could change the balance of the war, or a journalist who is trying to expose the truth about the war to the world. These types of characters can bring a different perspective to the story compared to the military - focused characters.
Shirou is obviously a main character. Often, Saber would still be a major part as well, since she has a strong connection with Shirou in the original story. Other Servants and Masters from the original Holy Grail War concept might also appear.
In many Whitebeard War fanfictions, Marco the Phoenix stands out. His ability to heal and his loyalty to Whitebeard are remarkable. Also, Squard is often a memorable character. His betrayal and then possible redemption can be a very interesting arc within the fanfiction. He adds an element of internal conflict within the Whitebeard Pirates which makes the story more complex.
The golden trio, no doubt. Harry, who has to find his place in a world that has changed so much after the war. Ron, who might be exploring new career opportunities in the wizarding world. Hermione, who could be using her knowledge to bring about positive changes. And don't forget their families. The Weasleys, especially, would be an important part of their post - war lives as they are like a second family to Harry.
