Without having read the graphic novel, it's hard to say precisely. However, it's common for this type of story to have a protagonist who is trying to achieve the status of 'king of the hill'. There could be an antagonist who stands in his way, and perhaps some side characters like his family or comrades who either support or complicate his efforts. Maybe there's a wise old character who gives advice, or a young upstart who challenges the main character's claim to the 'hill' in different ways.
I don't know for sure since I haven't read it. But it could have a lead character who is the main contender for the 'king of the hill' title. There might also be some friends or foes around him that play important roles in his journey.
Since I haven't had the chance to read the 'king of the hill graphic novel', I can only speculate. There may be a central character, let's call him Jack for example. Jack might be ambitious and determined to be the king of the hill. Around him, there could be his best friend Tom, who is always there to back him up, and a rival named Bill who is constantly trying to outdo Jack. There might also be a female character, say, Lucy, who has her own ideas about who should be the king of the hill and tries to influence the outcome through her own means. These are just possible characters based on what we generally expect from stories about competing for a top position like 'king of the hill'.
