Without having read 'Prodigal Days: The Untold Story', it's impossible to determine the main characters. They could be ordinary people who found themselves in extraordinary situations during those prodigal days, or perhaps well - known figures whose untold stories are being revealed.
Since I don't know the details of this 'Prodigal Days: The Untold Story', I can't say for sure who the main characters are.
I'm not sure specifically as I haven't read it. It could be about a period of time full of wasteful or wayward behavior ('prodigal days') that has some hidden or unspoken aspects ('the untold story').
The main characters are likely to be the Original vampires like Klaus, Elijah, and Rebekah.
The main characters in the prodigal son story are the father and the two sons. The prodigal son is the one who takes his inheritance early and goes off to live a wild life. The other son stays at home and works on the family property. And the father, who shows great love and forgiveness towards the prodigal son.
The Prodigal Son story features three key characters. The prodigal son is at the center of the narrative. He's young and impulsive, choosing to leave his family and waste his inheritance. His father is a very important character. He is loving and forgiving, showing great mercy when his son returns. The older brother also plays a significant role. He's more dutiful but also shows envy and a lack of understanding when his wayward brother is welcomed back.
The main character in the 'prodigal wife story' is the wife. However, depending on the nature of the story, there could be other significant characters. Her husband is likely to be involved as her actions will impact their relationship. Maybe there are neighbors or community members who notice her prodigal behavior and have an opinion about it. Additionally, if the story has a moral or redemptive arc, there could be a mentor - like figure who tries to guide the wife back to more responsible behavior.
In the 'Karate Kid Untold Story', the Karate Kid is surely one of the main characters. But there might be a mentor figure from his early days who taught him some basic martial arts principles. There could also be some local kids who were part of his karate - learning group at the very beginning. These kids could have different personalities and goals, some might be in it just for fun while others were more serious. And his family, especially his father who might have had an opinion on his son's interest in karate, would also be key characters in this untold story.
I'm not sure exactly who the main characters are without more information. But they could be the prisoners who planned and executed the escape.
The main character would definitely be the Karate Kid. Alongside him, his sensei would be a key figure. There could be other important characters such as his family members. His mother or father might be more involved in this untold story, perhaps they had some reservations about his karate training initially. And there could be a local bully or a group of bullies with more complex backstories than just being the antagonists, which could add more depth to the overall story.
In this 'Family Guy The Untold Story', the main characters remain the familiar faces from the regular 'Family Guy' series. Peter Griffin, the overweight and clumsy father figure, is bound to be a central part of the story. His wife Lois, who has to deal with Peter's craziness while taking care of the family. Stewie, the baby with a sophisticated vocabulary and grand plans, is a character full of surprises. Meg, the daughter who often endures a lot of family - related embarrassments. And Brian, the family dog who is not just a pet but an integral part of the family's adventures. Additionally, other characters from the town like Glenn Quagmire and Cleveland Brown might also make appearances and contribute to the story.
I don't know for sure as I haven't read or watched it. Maybe some of the characters from the first 'The Great Escape' return, like the ones who were the masterminds behind the initial escape plans.
