In the 'Mouse Guard Graphic Novel', the main characters are a group of mice that form the Mouse Guard. Saxon is a strong and fearless mouse. Kenzie is the brains behind many of their plans. Lieam is young but very capable. There are also other mice that they interact with in their community, like the elders who give them advice and the common mice they are sworn to protect. Each character has their own backstory and development throughout the stories in the graphic novel.
The main character is surely the guard. There could be a villain or a group of antagonists that he has to face. Maybe there's also a mentor figure for the guard, someone who has taught him the skills he needs for his job and offers him advice throughout the story.
Since I don't know the exact 'the mouse graphic novel', it's difficult to say. But likely, the mouse itself would be a main character. There could also be other animals like cats, birds, or other mice that play important roles, either as friends or foes of the main mouse character.

Given the title 'little mouse graphic novel', the little mouse is the central character. However, it could be accompanied by other characters. There might be an owl that serves as a wise guide in the mouse's adventures. There could also be a family of squirrels that the mouse befriends. And don't forget about potential antagonists, like a group of naughty rats that try to take over the mouse's territory. All these characters would interact with the little mouse and help drive the story forward.
Obviously, the cat and the mouse are the main characters. The cat is probably the pursuer, always on the lookout to catch the mouse. And the mouse is the one being chased, using its wits to escape the cat's clutches. There might be other minor characters as well, like a bird or a fish that might play a small part in the story, but the cat and the mouse are the stars.
I don't know for sure, but it's likely that the mouse girl herself is one of the main characters. There might also be her friends or family members, like a wise old mouse that gives her advice, or a younger mouse sibling she has to protect.
