There could be a boy from District 4 who is an expert fisherman. He uses his knowledge of water and fishing to survive in the arena. He might form an alliance with the girl from District 12, and together they face the challenges of the 50th Hunger Games. He is also very clever and can outwit other tributes.
Perhaps an older brother who volunteers to take his younger sister's place in the 50th Hunger Games. He has a strong sense of family loyalty and his journey in the Games could be about protecting the other tributes who remind him of his sister.
It could be about a new set of tributes. Maybe there's a tribute from an unexpected district who has a unique skill, like being able to communicate with animals. This skill gives them an edge in the arena, leading to all kinds of new alliances and betrayals.
There could be a mentor character who was a previous Hunger Games winner and is now guiding the new tributes. This character might have their own secrets and motives, and their backstory and how they interact with the tributes can make them a popular and complex character in the fanfiction.
There could be a disabled tribute from an unknown district. Despite his physical limitations, he has a brilliant mind and uses his strategic skills to form alliances and stay alive in the 73rd Hunger Games.
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.
A girl from District 12 could be a great main character. She could be different from Katniss, maybe she's more of a strategist than a hunter. She uses her wits to form alliances and outsmart her opponents in the arena.
A boy from District 4 who is an expert fisherman. He's not just physically strong but also very clever. He could use his fishing skills to catch food in the arena and also use the fishing nets as weapons or to set traps for other tributes. His backstory could be that he wants to win the Games to bring pride back to his district which has been overlooked in recent years.
Perhaps an older tribute from a previously overlooked district. He has been observing the Hunger Games for years and has a secret plan. He has a lot of knowledge about the Capitol's tactics and uses this to outwit the Gamemakers and survive in the 100th Hunger Games.
One main character could be a young girl from District 9, who is really intelligent and uses her wits to survive. She might form an alliance with a boy from District 12, who is known for his speed and agility. They make an unlikely duo but their combined skills help them in the games. There could also be an older tribute from District 7, who has a lot of experience in the forests and uses that to his advantage in the arena.
A girl from District 11 who is an expert at climbing trees and has a strong sense of justice. She could be one of the main characters, using her skills to survive in the arena and also standing up for the weaker tributes.
