I'm not sure exactly as I haven't read the whole novel, but likely the newbie is one of the main characters. There might also be characters who are in contrast to the newbie, like those who are initially stronger but get overshadowed.
Since it's about a newbie who is too strong, the newbie must be a central character. There could be mentors or antagonists. Mentors who try to guide the newbie's use of their strength, and antagonists who see the newbie as a threat to their own power or goals. For example, an antagonist might be a powerful figure in the existing power structure who wants to keep the newbie in check.
The newbie is surely a main character. There may also be supporting characters like friends or comrades of the newbie. These friends could either be those who are inspired by the newbie's strength or those who are protected by the newbie. Their relationships with the newbie would play an important role in the story's development.
The unique plot might be the key. A newbie being overly strong goes against the common tropes, creating unexpected twists and turns in the story.
The main character is obviously the dad who is too strong. And there are probably his family members like his wife and children as important characters as well.
