The main characters could be a combination of the most powerful or iconic figures from both. In Emerald Twilight, it could be the protagonist who has some extraordinary ability. In the Harry Potter world, it could be Dumbledore or Voldemort. Their interactions, whether it's a fight or an alliance, could be central to the fanfiction's plot. Also, there could be new characters created by the author to drive the crossover narrative forward.
Since it's a crossover, it might feature the central hero from Emerald Twilight. And in the Harry Potter side, it could include characters like Ron. However, the author might also introduce original characters that are important for the crossover plot, characters that act as a bridge between the two different universes and their storylines.
I'm not sure specifically as it depends on the particular fanfiction. But it could be a mix of the main characters from Emerald Twilight and some well - known characters from Harry Potter, like Harry himself or Hermione.
One interesting concept could be the combination of the Emerald Twilight storyline with the magical world of Harry Potter. Maybe it involves characters from Emerald Twilight having to adapt to the rules of magic in the HP universe, like a superhero trying to use their powers in Hogwarts.
Without reading the 'emerald twilight graphic novel', it's difficult to determine the main characters. But in many graphic novels, there's often a central character who drives the story forward. This character could be a young adventurer, or perhaps an older, more experienced figure.

For example, there could be a wise mentor type of character, or a feisty and impulsive sidekick.
Hal Jordan is one of the main characters. His actions drive the story forward. Also, there are other Green Lanterns like Kilowog who play important roles in the events of the graphic novel.
Sinestro can be an interesting character to focus on in an 'emerald twilight fanfic'. His relationship with the Green Lanterns, especially Hal Jordan, was complex.

Also, Guy Gardner has a fiery personality. Focusing on him could add a lot of action and conflict to the fanfic as he reacts to the events of Emerald Twilight.
One interesting story could be where the magical world of Harry Potter intersects with the vampire - werewolf lore of Twilight in Hogwarts. Maybe a Twilight character ends up at Hogwarts as an exchange student and has to navigate the magical classes and the politics within the school, all while hiding their true nature as a vampire or werewolf.
Bella could also be a main character. She might be the one who bridges the two worlds. Her connection to both the human and supernatural in Twilight could help her in Sky High, where she'd have to navigate a school full of students with extraordinary abilities while also dealing with her own unique situation.
