The main characters might include the regular One Piece crew, but perhaps there's also a new character who is the 'gamer' in the story. This gamer character could be the catalyst for all the new gaming - related events that happen in the fanfic. They might befriend the Straw Hat Pirates and teach them about the strange game - like mechanics that are now a part of their world. Or, it could be that one of the existing characters, say Usopp, discovers a strange device that gives him gamer - like powers, and then he becomes a central figure in this new type of adventure within the One Piece world.
It's hard to say without reading it, but it could be the original One Piece characters like Luffy, Zoro, and Nami, just with new roles or abilities related to the gaming aspect.
Most likely the main characters would still be the Straw Hat crew. Luffy would surely be a central figure as he is in the original One Piece. His carefree and determined nature would probably be adapted to fit the gamer - style story.
Luffy is usually one of the most popular characters. His carefree and determined nature in the original One Piece makes him a great fit for the gamer fanfic world. He can be the one leading the crew on in - game adventures and taking on powerful foes. Another popular one is Zoro. His badass swordsmanship skills are always exciting to read about in the context of a gamer fanfic, where his skills can be further enhanced or have new twists.
In 'one piece the gamer fanfic', it may center around a gamer who somehow gets transported into the One Piece world. This person then uses their knowledge of games to interact with the characters and situations in the One Piece universe. They could introduce new strategies for battles, like using game - style combo attacks, or they might even try to 'hack' the world's rules in a sense, creating a really unique and exciting story full of unexpected twists and turns.
Ace was also a very popular character in One Piece gamer fanfiction before his death. His fire - based powers and his connection to Luffy made him a great addition to any story. In fanfictions, he could be a powerful ally or a challenging boss depending on the plot. Trafalgar Law is also getting more popular in these types of fanfictions. His devil fruit ability and his complex personality make for some interesting plot twists in a gamer - style One Piece story.
Perhaps there's a family that is part of a secret organization in the One Piece world. The main characters could be the parents who are high - ranking members and their children who are being trained to take over in the future. They might be involved in espionage and other undercover operations.
Maybe it's a new pirate crew led by a character with a Devil Fruit power that can nullify the OC's Gamer abilities. This pirate captain is extremely ambitious and wants to rule the New World. He views the OC as an obstacle in his path because the OC has the potential to disrupt his plans, especially if they can use their Gamer skills to form alliances against him.
In many of these fanfics, All Might also plays an important role. Since he's Izuku's mentor, he often interacts with Izuku as he discovers and hones his gamer - related powers. And Bakugo Katsuki is usually there too. His rivalry with Izuku adds an extra layer of tension and drama to the story, especially when Izuku starts to gain an edge with his gamer skills.
It might have a group of friends who are all gamers. They could each have different gaming styles and personalities, like one who is super competitive, another who is more into the story aspect of games, and they all come together to form a unique dynamic within the fanfic. For instance, they might team up to compete in a big gaming tournament.
I don't know the specific main characters in 'the ninja gamer fanfic' as it can vary greatly depending on the author's creation. But it could be a ninja - named protagonist like 'Kai' who is also a top - notch gamer.
Often, the main character is the gamer who has been inserted into the DxD world. He brings a fresh perspective and different set of skills compared to the native characters.
