Maybe there are some human characters too, if the story involves the connection between humans and dogs. It could be a scientist who was involved in some experiment that led to the current situation, or a group of survivors who encounter the dogs and have to decide whether to help them or not. However, since it's about the last dogs, the focus would likely be mainly on the dogs' perspective and their journey.
There could be different types of dogs with different personalities. For example, there might be a young and curious pup who is just starting to understand the harshness of the world they live in. And there could be an older, wiser dog who has seen more of the world's decline and tries to guide the younger ones. There may also be some antagonist characters, perhaps other animals that compete with the dogs for the scarce resources in this dystopian setting.
Dystopian novels usually explore themes like the breakdown of society, loss of freedom, and the struggle for survival. In the case of 'The Last Dogs: The Vanishing', it could be that the vanishing refers to the disappearance of something important in the world of the last dogs. Maybe it's their natural habitat, or other species they depend on. The story might follow the dogs as they try to adapt and find a way to keep their kind alive in a world that is increasingly hostile.
Since the novel is about a vanishing game, the main characters might be those who are directly affected by the game's disappearance. It could be a group of friends who used to play the game together and now are on a quest to find out why it's vanishing. Or perhaps it's a single character, like a young person who discovers this vanishing game and tries to uncover its secrets, while also dealing with personal issues along the way.
The main characters in 'the vanishing half historical fiction' could be diverse. There might be a character who is a historian or a storyteller in the story, whose job is to document the history of the 'vanishing half'. There could be a mother figure trying to protect her children from the forces that are causing the vanishing. And perhaps a young man who is in love with a girl from the 'vanishing half' and is trying to find a way to save her and her community from disappearing in the historical context.
The two main characters are usually the driver and the hitchhiker. The driver is the one who offers the ride and is often left perplexed by the vanishing of the hitchhiker.
I don't know as I haven't read it. But likely, the vanishing girl herself is a main character.
In 'the pawn dystopian novels', it's possible that the main characters are not just the pawns but also those who control them. However, the focus is more on the pawns. They could be individuals from different backgrounds, like a factory worker, a student, or a street vendor, all of whom are affected by the dystopian system. Their stories of trying to resist or adapt to this new world order would be central to the narrative. For example, a young 'pawn' might discover a way to fight against the oppressors and inspire others to do the same, becoming a key figure in the story.
Since I don't know the details of the story, it's difficult to say. But probably the star soldiers themselves are main characters. There might also be some sort of authority figures in the star soldier organization or perhaps some characters on Earth who play important roles before it vanishes.
Juliette is a main character. She has a special power that she has to deal with in this dystopian world. Adam is also important. He has a connection with Juliette and they go through a lot together. Warner is another key character. He's complex, being both a villain and someone with his own motives and desires.
Thomas is one of the main characters. He is a newcomer to the Glade and plays a crucial role in trying to find a way out of the maze. Another important character is Minho, who is a Runner. He has explored a lot of the maze and has valuable knowledge about it. There's also Newt, who is like a leader figure in the Glade.
One of the main characters is Emiko, the Windup Girl. She is a product of genetic engineering and endures a lot of mistreatment. Anderson Lake is a key figure, an American businessman who gets entangled in the complex politics and power struggles of the novel's setting. There is also Hock Seng, who has his own story of survival and trying to make the best of the difficult situation in this dystopian society.
