There might be a secondary character who is a mentor - like figure. They could have been a previous Hunger Games winner and now they are guiding the main character with their knowledge and experience. They might offer advice on strategies for survival, like how to make the best use of the resources in the arena.
Another main character could be an antagonist, someone who is very competitive and ruthless in the Hunger Games. They see the main character as a major threat and will do whatever it takes to eliminate them. This character might have some special skills or advantages that make them a formidable opponent in the arena.
Obviously, 'Merome' which is likely a combination or reference to two main characters. But without reading the specific fanfic, it's hard to say exactly who they are. They could be original characters created for the fanfic within the Hunger Games universe.
I'm not sure specifically as it depends on the fanfic. But it could be a new set of tributes from different districts. Maybe a strong - willed girl from District 4 and a smart boy from District 11.
Most likely, the main characters would be the well - known members of Magcon. They could be Nash Grier, Cameron Dallas, etc.
It's hard to say without reading the fanfic specifically, but it could be characters who are part of the Capitol elite. Maybe a game - maker who has a different view on the Hunger Games than others in the Capitol.
I'm not sure specifically as I haven't read this fanfic. But it could be new tributes created by the fanfic author.
There could also be a plot where the main character discovers a secret about the Hunger Games that no one else knows. Maybe it's a way to hack the system that controls the arena or a hidden passage that leads to safety. This discovery then changes the whole dynamic of the Games for them, and they use it to their advantage while also trying to keep it a secret from the Gamemakers.
A young, brave pilot from a small, rebel - affiliated starship could be a main character. He's got great flying skills and uses them to his advantage in the arena. For instance, if there are flying obstacles or challenges, he can navigate through them easily.
Since I don't know the exact fanfic, it could feature well - known victors like Katniss Everdeen and Peeta Mellark. They are central characters in the Hunger Games series and are likely to be important in a fanfic about victors.
Obviously Naruto himself could be a main character. He has the skills and the charisma. Sasuke could also be a main character. His brooding nature and powerful ninja abilities would make him a force to be reckoned with in the Hunger Games arena. Sakura, with her medical ninjutsu and growing combat skills, could also be a key character.
I'm not sure specifically as it's a fanfic, but they could be some original characters created by the fanfic author who are outsiders in the Hunger Games world. Maybe a group of young rebels who are determined to change the system.
