Aang is one of the main characters. He's the Avatar, with his unique ability to bend all four elements. Katara also plays a major role. She's a water bender and Aang's friend and ally. Zuko is another key character, initially an antagonist but with a complex character arc.
In 'Best Avatar Graphic Novel', Aang is central as the Avatar. He's on a journey to master the elements and bring balance to the world. Katara is by his side, not only as a water bender but also as someone who offers emotional support. Zuko, the banished prince of the Fire Nation, is constantly evolving in the story. His search for redemption while dealing with his family issues makes him a very interesting main character.

I really don't have enough information to name the main characters. But thinking about common avatar stories, there could be a young avatar who is just discovering their powers. They might be joined by an older, wiser character who has knowledge of the avatar world. There could also be a group of friends or allies who each have their own unique skills and personalities. And of course, there could be an enemy or a group of enemies who are out to disrupt the balance in the avatar world that the main characters are trying to protect.
The main characters could be a mix of old and new faces. The old characters from the Avatar series would bring in the familiarity and the connection to the established story.

They could be from different nations within the Avatar world, each with their own unique abilities and goals, all intertwined with the central theme of the promise in the graphic novel.

And there may be other characters such as the various leaders and warriors of the Na'vi tribes that play significant roles in the story as well.
