In 'Hercule Poirot's Christmas', the main character is, of course, Hercule Poirot. He is a meticulous detective with an egg - shaped head and a remarkable ability to understand human nature. The other characters include the family members of the victim, such as the patriarch's sons and daughters, each with their own secrets and motives that Poirot has to explore.
In 'The Night Before Christmas', the main character is Santa Claus himself. He is the mysterious figure who arrives on his sleigh with reindeer, bringing joy and presents to children. The family in the house waiting for his arrival can also be considered important characters as they are part of the mystery of Santa's visit and the magic of Christmas.
I'm not sure specifically as I haven't read it in detail, but it could be a detective trying to solve the crime, or some ordinary people who get caught up in the mystery.
I'm not entirely sure, but it could be the main character from Hogwarts Mystery. Maybe their friends from different houses too, like the Gryffindor, Hufflepuff, Ravenclaw, and Slytherin friends they've made throughout the game.
In 'A Christmas Carol', Ebenezer Scrooge is a main character. He is a stingy old man at the start. Then there are the spirits - the Ghost of Christmas Past, the Ghost of Christmas Present, and the Ghost of Christmas Future. Bob Cratchit, Scrooge's clerk, is also important, along with Tiny Tim, Bob's sick son.
The Doctor is obviously one of the main characters. He's the time - traveling hero who gets into all sorts of adventures.
The elves are also main characters. They are the ones who work hard in the North Pole making toys. They are often depicted as small, nimble, and very creative beings in Action Christmas Stories.
The main characters might also include children. They could be the ones who are most excited about Christmas on the prairie. They might be looking forward to getting a small gift, seeing the Christmas decorations, or eating a special treat. Their innocence and joy could be a central part of the stories in 'Prairie Christmas Stories'.
Also, there could be some Christmas - specific characters like Santa Claus or elves if the stories have a more magical take on Christmas. They would interact with Thomas and add to the festive feel of the stories.
The main characters are surely the Avengers themselves. This includes Iron Man (Tony Stark), Captain America (Steve Rogers), Thor, Hulk, Black Widow, and Hawkeye. They are the ones who would be at the center of any story in the 'Avengers Christmas Stories' collection, whether they're saving Christmas or just having a holiday celebration together.
In some of the stories, there are also kind-hearted adults. These adults might be a simple baker or a poor fisherman. They show great compassion towards the children or other needy people. For example, an old woman who shares her last piece of bread with a hungry child. They play important roles in spreading the Christmas spirit.
Maybe Santa Claus and his elves are the main characters. They are very common in Christmas stories.
