The main character is clearly the boy. But we can speculate about other potential characters. If this is a mystery - type story, there could be a detective - like character who catches the boy in the shiny bikini. In a more humorous story, there could be a group of onlookers who become important characters as they react to the boy being caught in the shiny bikini. Without more information from the story itself, it's hard to be certain about all the main characters.
Based on just the title, the only obvious main character is the boy. However, depending on the nature of the story, there might be other important characters. For example, if it's a story set at the beach and the boy is caught by a lifeguard while wearing the shiny bikini, then the lifeguard would be another main character. Or if it's a story about a fashion show gone wrong and the boy is caught by the show organizers, they would be significant characters too.
I'm not sure specifically what this 'boy caught in shiny bikini story' is about as the title is rather unclear. It could potentially be a story where a boy is found or gets into a situation while wearing a shiny bikini, perhaps in a comical or unexpected context.
Obviously, the main characters are the boy and his grandmother.
There could be a wide range of characters. It might have a young boy as the protagonist who is always curious about the shiny things around him. And there could be his friends, like a smily little girl who is always optimistic. There might also be some antagonists, perhaps a jealous character who tries to take away the shiny things that bring smiles to others.
Well, there would definitely be the boy himself. Maybe his best friend who catches him in the situation.
It's possible that the main characters are a group of friends. They might all have different goals when it comes to shiny Pokemon. One could be interested in collecting as many shiny Pokemon as possible, while another might be focused on finding a specific shiny Pokemon that has a special meaning to them. And throughout the stories in 'First Shiny Pokemon Stories', we follow their adventures and experiences with shiny Pokemon.
Maybe a memorable one is when a boy stole a bikini thinking it was a prank, but it turned into a big problem when the owner found out and told his parents. He then learned a valuable lesson about respecting others' property.
Obviously, Ash is one of the main characters. He is the trainer who catches the shiny Pokemon. His Pikachu also plays a significant role, as it's always by Ash's side and could potentially have some interesting interactions with the shiny Pokemon.
The main characters are Spongebob, Patrick, and Sandy. Spongebob is the enthusiastic and optimistic sponge. Patrick is his dim - witted but loyal friend. And Sandy is the tough and intelligent squirrel from Texas.
As I don't know the specific 'Caught 2015' work, it's difficult to say who the main characters are. But if it's about a crime, the main characters could be the criminal, the detective or police officer who caught them.
I don't know as I haven't read the novel. It could be a male protagonist who is the central figure in the story.
