There's no official information yet. However, if it follows the pattern of the previous books, there will probably be a strong - willed protagonist from one of the districts, someone who has to fight in the Hunger Games. And there will likely be other supporting characters, such as a mentor figure, a love interest, and some rivals within the Games.
Since it's not out yet, we can't be sure. But it could be descendants of the original characters like Katniss and Peeta. Or it might introduce entirely new characters from districts we haven't seen much of before.
Haymitch Abernathy is a key character. He is a former Hunger Games winner and becomes a mentor to Katniss and Peeta. President Snow is also significant. He represents the power - hungry and cruel leadership of the Capitol.
Katniss Everdeen is one of the main characters. She is a strong - willed girl from District 12 who volunteers for the Hunger Games. Peeta Mellark is also a main character. He is from the same district as Katniss and has feelings for her.
Haymitch Abernathy is a key character too. He is the only living victor from District 12 and becomes Katniss and Peeta's mentor in the Hunger Games. He is often drunk but has a lot of knowledge about the Games and how to survive them.
I'm not sure exactly as I haven't read it yet, but I assume there will be characters related to the founders or early influencers in Panem. Maybe some important Capitol figures or leaders from the districts who played a role in setting the stage for the Hunger Games.
The main characters include Katniss Everdeen, a brave and skilled girl from District 12 who volunteers for the Hunger Games. Peeta Mellark, the male tribute from District 12, is another important character. Gale Hawthorne, Katniss' friend back in District 12. And then there's President Snow from the Capitol who is the main antagonist, trying to maintain the Capitol's control over the districts through the Hunger Games.
The main characters include Katniss Everdeen, who is strong - willed and a skilled archer. Peeta Mellark, who is kind - hearted and has a complex relationship with Katniss. And then there's Haymitch Abernathy, who is their mentor and helps them prepare for the games, though he has his own issues due to his past experiences in the games.
It's possible that there will be a character who has a connection to the later main characters in the original Hunger Games story. Maybe a relative or someone who inspired them in some way. This character could be the center of the prequel's plot, and through their story, we can see how the events of the prequel lead to the situation in the original Hunger Games.
The new girl herself would be a main character, of course. She could be named something like Ava. There might also be a male tribute from a different district, like Finn, who becomes her ally. And the Capitol's representative, like Seneca Crane, could also be a significant character as he tries to control the games and the new girl's fate.
The main characters include Katniss Everdeen. She is brave and determined to bring down the Capitol. Peeta Mellark, her counterpart from the games, whose mind has been messed with by the Capitol. And President Snow, the dictator - like leader of the Capitol who will do anything to keep his power. There are also other characters like Gale Hawthorne who plays an important role in the rebellion, and Finnick Odair, who is a strong ally to Katniss in the fight against the Capitol.
The main characters include Katniss Everdeen, a strong - willed girl from District 12. She's a skilled hunter and becomes a symbol of resistance. Peeta Mellark, a baker's son, is another main character. He has a kind heart and forms a complex relationship with Katniss. Then there's Haymitch Abernathy, their mentor who has his own demons but tries to guide them through the Games. And of course, President Snow, the tyrannical leader of the Capitol who will stop at nothing to maintain his power.
