Maybe there's a castaway as the main character. They might be someone who was in a shipwreck and now has to fend for themselves at sea. There could also be other characters that appear in the character's memories or hallucinations, like their family or friends from back home, which would add depth to the story.
I'm sorry, without reading the graphic novel, I can't tell who the main characters are.
Since I haven't read 'the sea of monsters the graphic novel' specifically, I can only guess. There might be a main character who is a young person with a mysterious past. This character could be driven by a desire for adventure or to prove themselves. There could also be an older mentor figure who guides the younger ones. And perhaps there are some side characters who add humor and variety to the story, like a bumbling but kind - hearted sailor or a sassy magical creature that they encounter on their journey through the sea of monsters.
There's no way to tell for sure, but it might be a sea captain and a mermaid. The sea captain could be on a quest related to the pearl, and the mermaid might be protecting it or have a connection to it.
I'm not entirely sure, but it could be some brave adventurers or heroes.
Since it's called 'queen of the sea graphic novel', the queen is likely the central character. There could be antagonists too, like a power - hungry warlord from another part of the sea or a group of mutinous pirates. Maybe there are also characters who are loyal to the queen, such as her guards or her childhood friends who play important roles in her story, like helping her make difficult decisions or providing emotional support during tough times.
It might feature the captains of the various pirate ships. These could be characters who are on a quest for the ultimate treasure, and they lead their crews through dangerous waters and against powerful enemies. There could also be some side characters like the shipwrights or the tavern keepers who play important roles in the story by providing resources or information.
I'm not certain as I haven't read it, but I assume the girl from the sea is a main character for sure.
Well, the main characters start with Captain Nemo. He is a very interesting character as he has his own reasons for staying away from the surface world and exploring the deep sea. Professor Aronnax is a learned man who gets the opportunity to study the ocean in a way no one else has. His servant Conseil is a bit of a sidekick but also has his own charm. And Ned Land, the harpooner, adds some action and a different view. He is more concerned with getting back to the surface and his normal life at times. He provides a contrast to the more academic characters.
The main characters are likely Captain Nemo, Professor Aronnax, Conseil, and Ned Land.
I'm not sure exactly, but surely the girl from the sea is one of the main characters. There might be some characters from the land who interact with her as well.
