I'm not sure exactly without reading the novel, but typically there would be the hero themselves. They are the central figure around which the story revolves.
There could also be a mentor figure. In many hero - centered novels, there is someone who guides the hero, teaches them skills or gives them important advice. This character might be an old wizard, a wise warrior, or just an experienced person in the world of the story. And then, there might be an antagonist. This is the person or force that opposes the hero. It could be a villain with evil plans, or a natural disaster - like force that the hero has to overcome.
It might be centered around the hero's heart in a more metaphorical sense. Maybe it represents their courage, love, or their capacity for great deeds. For example, if the hero has a 'big heart' in the story, it could mean they are very kind and always ready to help others, which could be a major theme.
The main characters include Percy Jackson, who is well - known from previous stories. Then there's Jason, a brave hero with his own set of skills. Piper is another important character, a strong - willed girl. Leo, the witty and mechanical - minded character, is also a main part of the story. These characters work together, each bringing their unique abilities to face the challenges in the 'heros of olympus graphic novel'.
There could also be characters like Jason Grace. He has his own powers and backstory, and in the overall series, he plays a significant role in the events. His presence might be crucial in the plot of book 3 as well, whether it's in terms of leadership or in dealing with the various challenges the heroes face.
I'm not sure specifically as I haven't read it in full, but likely there is the main character who quits the hero's party. There may also be other members of the party who play important roles, like the leader of the party or a close friend of the protagonist.
Obviously, the hero's wife is one of the main characters. She is likely to be the central figure through whose perspective we see the story unfold. And of course, the hero himself is another main character. Their relationship is likely to be at the core of the plot.
Percy Jackson is one of the main characters. He's a demigod with a lot of power and a big role in the story. He's been part of the previous series too and continues to be a key figure in the 'Heroes of Olympus' graphic novels.
I'm not entirely sure as I haven't read it in detail. But typically, there would be the character who is banished. There might also be members of the hero's party who play a role in the banishment or are relevant to the story later on.
Since I haven't read it, I can't say for sure. But likely there is the character who believes it's their destiny to be the savior, and of course, the hero who needs to be saved.
I'm not entirely sure without reading it, but it probably features characters from the Heroes of Olympus universe like Percy Jackson.
I'm not sure exactly as I haven't read it. But usually in such novels, there could be a protagonist who drives the story forward. Maybe it's a young person on a journey of some kind.
