As the specific story isn't clear, in many of Dahl's stories there are characters that are outsiders in a way. They might not fit in the normal world but during Christmas, they find a place or a purpose. There could also be a mentor - like character who guides the main character through the Christmas adventures, teaching them important lessons about life and the spirit of Christmas.
The main themes in Roald Dahl's Christmas story are likely to include the spirit of Christmas itself. This means things like the festive cheer, the lights, and the decorations all contribute to a feeling of celebration. There might also be a theme of discovery. Maybe the characters discover something new about themselves or others during Christmas. Additionally, a theme of hope could be present. Christmas can be a time when characters look forward to a better future, and Dahl might have incorporated this into his story.
There are various main characters. Some are children with a certain naivete, like Charlie in some of Dahl's works. There are also adults who can be cruel or strange. For example, the witches in 'The Witches' are main characters in the dark story. They are cunning and have their own evil plans.
In 'James and the Giant Peach', James is the main character. He is a young boy who has to deal with a difficult situation at home and then embarks on an adventure inside the giant peach with his new friends like the Centipede, the Earthworm and the Ladybird.
The main characters in 'The Swan' by Roald Dahl are a group of boys. These boys play a crucial role as they are the ones who encounter the swan. Their personalities, which might be a mix of curiosity, naivete, and in some cases, a lack of kindness, are what shape the story. The swan itself can also be considered a main character in a sense, as it is the object of the boys' attention and the victim of their actions. However, the boys are the ones through whom the story's themes of power, cruelty, and moral exploration are mainly expressed.
Since I'm not sure of the exact story, it could be the tortoise itself as one of the main characters. And perhaps there's another animal or a special character that the tortoise has a relationship with, like a kind - hearted bird or a magical little mouse.
Well, there are many. For example, in 'Matilda', Matilda Wormwood is the main character. She is a very smart girl. In 'The BFG', there is the Big Friendly Giant and Sophie. Sophie is a little girl who befriends the BFG. And of course, in 'Charlie and the Chocolate Factory', Charlie is the central figure who gets the golden ticket to enter the factory.
Charlie Bucket is a main character from 'Charlie and the Chocolate Factory'. He is a kind and poor boy who gets a chance to visit Willy Wonka's amazing chocolate factory.
There are also other important characters like Willy Wonka in 'Charlie and the Chocolate Factory' who is the eccentric owner of the chocolate factory. These characters are all very memorable and add to the charm of Dahl's stories.
There's James in 'James and the Giant Peach'. He's a young boy who has a big adventure on a giant peach with his insect friends. And in 'The Fantastic Mr. Fox', Mr. Fox is the main character. He's clever and always manages to outwit the farmers who are trying to catch him. Also, in 'The Landlady', the landlady herself is a very important character with some rather strange behavior.
Main characters can include outcasts. People who don't fit into normal society. They might be the ones to encounter the horror first. Also, there are the victims. These are the characters who are at the mercy of the horror elements in the story. And sometimes there are tricksters. Characters who seem friendly but are actually leading others into horror.
