There are many different main characters. Some are brave explorers who venture into unknown lands or spaces. They are the ones who drive the action forward and face various challenges.
Often, the main characters are ordinary children. They could be a little boy or girl who lives in a small town or a big city. They might be shy or outgoing, but they always have some special qualities that make them stand out in the story.
Darwin is also a key character. He's Gumball's best friend and often accompanies him in their adventures, including those related to the ghost stories. Their friendship brings a lot to the table in terms of how they react to the spooky situations.
Since we don't have more information about these stories, the main characters could range from ordinary people like a young boy or girl on a journey, to more extraordinary characters like a wizard or a brave knight. Maybe there are also groups of characters as the main focus in some stories, such as a family or a team of adventurers.
Goku from 'Dragon Ball' is a classic. He is a Saiyan who loves to fight and is always looking for stronger opponents. His story spans from being a young boy on Earth to becoming one of the most powerful beings in the universe. His simplicity, love for food, and his unyielding will to protect his friends and family make him a great character. His battles are epic and the story keeps evolving with new threats and power - ups.
Anais can be part of the scary stories as well. She may be small but she's quite brave and often helps Gumball and Darwin out when they're in a spooky situation. For example, she might use her intelligence to figure out a way to escape from a haunted place or deal with a menacing creature.
The players of the Heat are likely the main characters. They are the ones on the court, facing challenges, making plays, and winning or losing games.
A young girl who is brave and curious. She might be the one who discovers the Green Man in the first place and then joins him on some of his adventures. She could bring a different perspective, being a human without any special powers but with a great deal of courage and determination. For example, in a story where they face a dangerous monster, she uses her wits to outsmart it while the Green Man uses his powers. Her character shows that ordinary people can also play important roles in extraordinary situations.
The main character is probably the person who wrote 'Amazing Grace'. Maybe it was John Newton.
There might be her friends or family members as important characters too. For example, her best friend who might be the first to notice when she's acting strange because of her superhero life. Or her parents, if they are still in the picture, and she has to keep her identity a secret from them.
Since I don't know the specific 'Amazing Grace short story', it's hard to say for sure. But it's likely that Grace is one of the main characters. There could also be other characters like her friends, family members, or people she meets during her journey.
